Allovir Inc

Overview

AlloVir, Inc. (“AlloVir”) is a biopharmaceutical company. AlloVir’s initial focus was on developing highly innovative allogeneic T cell therapies to treat and prevent devastating viral diseases. AlloVir’s innovative and proprietary virus-specific T cell (“VST”) therapy platform allows AlloVir to generate off-the-shelf VSTs designed to restore immunity in patients with T cell deficiencies who are at risk from the life-threatening consequences of viral diseases. This included: (1) posoleucel (ALVR105), an investigational off-the-shelf multi-virus-specific T cell therapy, which targeted six viral pathogens in immunocompromised individuals: adenovirus (“AdV”), BK virus (“BKV”), cytomegalovirus (“CMV”), Epstein-Barr virus (“EBV”), human herpesvirus-6 (“HHV-6”) and JC virus (“JCV”); (2) ALVR106, an allogeneic, off-the-shelf VST therapy candidate developed to target devastating diseases caused by four respiratory viruses: human metapneumovirus (“hMPV”), influenza, parainfluenza virus (“PIV”) and respiratory syncytial virus (“RSV”); and (3) ALVR107, an allogeneic, off-the-shelf VST therapy candidate designed to target hepatitis B (“HBV”)-infected cells with the aim of curing chronic HBV infections. On December 22, 2023, AlloVir announced the discontinuation of three Phase 3 registrational trials of posoleucel following separate, pre-planned Data Safety Monitoring Board, futility analyses that concluded the studies were unlikely to meet their primary endpoints. Specifically, AlloVir discontinued a multicenter, randomized, double- blind, placebo-controlled Phase 3 trial comparing posoleucel to placebo for the prevention of infection or disease due to AdV, BKV, CMV, EBV, HHV-6, or JCV in high-risk adult and pediatric patients after undergoing an allogeneic hematopoietic stem cell transplant. AlloVir also discontinued two multicenter, randomized, double- blind, placebo-controlled Phase 3 trials of posoleucel – one for the treatment of virus-associated hemorrhagic cystitis and the second for the treatment of adenovirus infection—both after allogeneic hematopoietic cell transplant. At this time, AlloVir does not intend to resume development of posoleucel or any other product candidates. In December 2023, AlloVir announced the decision to conduct a comprehensive review of strategic alternatives focused on maximizing shareholder value. AlloVir also engaged Leerink Partners LLC as its exclusive strategic financial advisor to assist in the process of exploring strategic alternatives, including the merger with Kalaris Therapeutics, Inc. (“Kalaris”).

In connection with the evaluation of strategic alternatives and to maximize capital preservation, AlloVir implemented a plan to reduce its workforce by approximately 95%. This workforce reduction plan was approved in January 2024, took place primarily during the first quarter of 2024, and was substantially completed by April 15, 2024.

On November 7, 2024, AlloVir, Kalaris and Aurora Merger Sub, Inc., a wholly-owned subsidiary of AlloVir (“Merger Sub”) entered into an agreement and plan of merger (the “merger agreement”), which contains the terms and conditions of the proposed merger. Pursuant to the Merger Agreement, among other matters, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, at the effective time of the Merger (as defined below), Merger Sub will merge with and into Kalaris, with Kalaris surviving as a wholly-owned subsidiary of AlloVir. This transaction is referred to in this Annual Report on Form 10-K as the “merger.” At the effective time of the merger, AlloVir is expected to change its name to “Kalaris Therapeutics, Inc.” and continue to be listed on The Nasdaq Capital Market, but trade under the ticker symbol “KLRS”. The surviving corporation following the merger is referred to in this Annual Report on Form 10-K as the “combined company.”

The merger is expected to close in the first quarter of 2025, subject to the satisfaction or waiver of various conditions, by each of the parties, at or prior to the closing of the merger, including, among other things, (i) the approval by AlloVir stockholders of (a) the issuance of shares of AlloVir common stock, which represent more than 20% of the shares of AlloVir common stock outstanding immediately prior to the merger, to Kalaris stockholders pursuant to the terms of the merger Agreement and pursuant to Nasdaq Listing Rule 5635(a) and (b) the change of control of AlloVir resulting from the merger, (ii) the adoption of the merger agreement by the requisite Kalaris stockholders, (iii) AlloVir’s net cash at the closing of the merger being no less than $95.0 million and (iv) other customary closing conditions. The merger was unanimously approved by the AlloVir board of directors. AlloVir is holding a special meeting of its stockholders on March 12, 2025, at 9:00 AM Eastern Time unless postponed or adjourned to a later date, in order to obtain the stockholder approvals necessary to complete the merger and related matters. If the merger is completed, the business of Kalaris will continue as the business of the combined company.

At the effective time of the merger, each issued and outstanding share of Kalaris common stock will be converted into the right to receive a certain number of shares of AlloVir common stock based on an exchange ratio (the “exchange ratio”). Under the exchange ratio formula in the merger agreement, upon closing of the merger, on a pro forma basis and based upon the number of shares of AlloVir common stock expected to be issued in the merger, it is expected that pre-merger Kalaris stockholders will own approximately 75.34% of the combined company and pre-merger AlloVir stockholders will own approximately 24.66% of the combined company, in each case, on a fully-diluted basis (excluding any shares reserved for future equity awards). Under certain circumstances, the ownership percentages may be adjusted upward or downward based on the level of AlloVir’s net cash at the closing of the merger.

The exchange ratio, and related pro forma ownership, assumes (a) a valuation of AlloVir of $116.0 million, which is subject to adjustment to the extent that AlloVir’s net cash at closing of the merger is above or below $100.0 million by more than $1.0 million (provided that AlloVir’s net cash at closing of the merger shall be no less than $95.0 million), in which case AlloVir’s valuation will be adjusted on a dollar-for-dollar basis by the difference of (i) its net cash at closing of the merger and (ii) $100.0 million, and (b) a valuation for Kalaris of $347.0 million.

Pursuant to the merger agreement, Kalaris is permitted to enter into a series of financings to fund its operations prior to the closing of the merger in an amount not to exceed $15.0 million in the aggregate on a to be converted post-money basis, with up to $7.5 million to be provided by AlloVir and up to $7.5 million to be provided by existing Kalaris stockholders (the “Additional Permitted Bridge Financing”). On January 10, 2025, as a part of the first tranche of the Additional Permitted Bridge Financing, Kalaris issued a convertible promissory note in an aggregate principal amount of up to $7.5 million to AlloVir (the “AlloVir Note”) under which AlloVir funded a principal amount of $3.75 million, and Kalaris issued convertible promissory notes in an aggregate principal amount of $3.75 million to existing Kalaris stockholders. Prior to the closing of the merger, Kalaris has the opportunity to receive an additional $7.5 million in the second tranche of the Additional Permitted Financing of which $3.75 million would be provided by existing Kalaris stockholders and the remaining $3.75 million would be provided by AlloVir. However, Kalaris no longer expects the second tranche of the Additional Permitted Financing to be funded. Upon the closing of the merger, the AlloVir Note will be cancelled and the aggregate amount outstanding under the AlloVir Note will be added to AlloVir’s net cash.

If AlloVir is unable to satisfy certain closing conditions to the merger agreement, or if other mutual closing conditions to the merger agreement are not satisfied, Kalaris will not be obligated to complete the merger. If the merger agreement is terminated under specified circumstances, AlloVir could be required to pay Kalaris a termination fee of $3.48 million or Kalaris could be required to pay AlloVir a termination fee of $10.41 million. In addition, in certain circumstances upon the termination of the merger agreement, AlloVir could be required to pay the reasonable costs and expenses of Kalaris in an amount not to exceed $580,000, or Kalaris could be required to pay AlloVir’s reasonable costs and expenses in an amount not to exceed $580,000.

AlloVir and Kalaris believe that combining the two companies will result in a combined company with promising science, a strong leadership team and substantial capital resources, positioning it to become a biopharmaceutical company focused on developing Kalaris’ lead product candidate, TH103.

AlloVir expects to devote significant time and resources to the completion of the merger. If the merger is not completed, AlloVir will reconsider its strategic alternatives and may pursue one of the following courses of action, which AlloVir currently believes are the most likely alternatives if the merger is not completed:

•

Pursue another strategic transaction similar to the merger. AlloVir may resume its process of evaluating other candidate companies interested in pursuing a strategic transaction and, if a candidate is identified, focus its attention on negotiating and completing such a strategic transaction with such candidate.

•

Continue to operate its business. AlloVir could elect to continue to operate its business and pursue licensing or partnering transactions. To continue to operate its business, AlloVir would require a significant amount of time and financial resources, and AlloVir would be subject to all the risks and uncertainties involved in the development of product candidates. There is no assurance that AlloVir could raise sufficient capital to support these efforts, that its development efforts would be successful or that it could successfully obtain the regulatory approvals required to market any product candidate it pursued.

•

Dissolve and liquidate its assets. If AlloVir is unable, or does not believe that it is able, to find a suitable candidate for another strategic transaction, AlloVir may dissolve and liquidate its assets. In that event, AlloVir would be required to pay all of its debts and contractual obligations and to set aside certain reserves for commitments and contingent liabilities. If AlloVir dissolves and liquidates its assets, there can be no assurance as to the amount or timing of available cash that will remain for distribution to AlloVir’s stockholders after paying AlloVir’s debts and other obligations and setting aside funds for commitments and contingent liabilities.

AlloVir’s future operations are highly dependent on the success of the merger and there can be no assurances that the merger will be consummated successfully. There can be no assurance that the strategic review process or any transaction relating to a specific asset, including the merger or any AlloVir asset sale, will result in AlloVir pursuing such a transaction(s), or that any transaction(s), if pursued, will be completed on terms favorable to AlloVir and its stockholders in the existing AlloVir entity or any possible entity that results from a combination of entities. If the strategic review process is unsuccessful, its board of directors may decide to pursue a dissolution and liquidation of AlloVir.

AlloVir’s proprietary VST manufacturing platform enables the rapid, robust and reproducible generation of single-virus and multi-virus specific cell therapeutic candidates for clinical use. AlloVir’s VST production process selectively expands polyclonal (CD4+ helper and CD8+ cytotoxic) virus-targeted T-cell populations. The critical components of AlloVir’s off-the-shelf VST platform, for which patents are issued and/or pending, include:

•

Methods of identifying immunodominant viral antigens in target viruses;

•

Cytokin TM, AlloVir’s selection algorithm to identify healthy donors from whom to generate VSTs that provide coverage to over 95% of patients in AlloVir’s targeted populations;

•

Methods of rapidly and selectively expanding polyclonal VSTsex vivo; and

•

Cytomatch TM, AlloVir’s algorithm to choose the appropriate partially human leukocyte antigen (“HLA”)-matched off-the-shelf VST therapy to deliver to each patient.

AlloVir has applied this expertise in the development of additional product candidates that may benefit high-risk individuals:

•

ALVR106 is AlloVir’s second off-the-shelf, multi-VST product candidate that targets devastating respiratory diseases caused by hMPV, influenza, PIV, and RSV. A Phase 1b/2 proof of concept clinical study of ALVR106 has completed enrollment of patients in Part A of the trial. AlloVir has stopped development of ALVR106, including discontinuing the trial pending the outcome of its review of strategic alternatives.

•

ALVR107 is AlloVir’s preclinical stage product candidate designed to target HBV-infected cells and with the aim of curing chronic HBV infections. Preclinical and investigational new drug application (“IND”)-enabling studies of ALVR107 to treat and cure HBV were completed in 2022 to support advancement into a proof of concept (“POC”) study. AlloVir has stopped clinical development of ALVR107 pending the outcome of AlloVir’s review of strategic alternatives.

AlloVir’s Highly Innovative Allogeneic VST Therapy Candidates

AlloVir’s pipeline of allogeneic, off-the-shelf VST therapy candidates is designed to restore virus-specific T-cell immunity in patients suffering from, or at risk for, life-threatening viral diseases. AlloVir’s proprietary VST therapy platform can be used to generate allogeneic cell therapies targeting single or multiple viruses at commercial scale. AlloVir owns worldwide development and commercialization rights to all of AlloVir’s cell therapies.

Posoleucel

AlloVir’s lead product candidate, posoleucel, is a multi-VST therapy targeting six viral pathogens: AdV, BKV, CMV, EBV, HHV-6 and JCV, which has the potential to fundamentally transform the treatment landscape for immunocompromised individuals.

AlloVir’s initial focus was to develop posoleucel in immunocompromised hematopoietic cell transplantation (“HCT”) and solid organ transplantation (“SOT”) patients who are at high risk for life-threatening viral infections as follows:

•

Treatment of virus-associated hemorrhagic cystitis (“HC”) (BKV and/or AdV) in HCT patients

•

Treatment of AdV infections in HCT patients

•

Prevention of multi-virus infections (AdV, BKV, CMV, EBV, HHV-6 and JCV) in HCT patients

•

Treatment of BKV infections in kidney transplant patients

Based on the strength of the posoleucel Phase 2 data for both treatment and prevention, the FDA granted posoleucel Regenerative Medicine Advanced Therapy (“RMAT”) designation for three indications—for the treatment of HC caused by BKV, for the treatment of AdV infection in adults and children following allo-HCT, and for the prevention of clinically significant infections and disease caused by posoleucel’s six target viruses. Similarly, based on data generated from the Phase 2 POC treatment trial and the critical medical need, the European Medicines Agency (“EMA”) has granted posoleucel PRIority Medicines (“PRIME”), designation for the treatment of serious infections with AdV, BKV, CMV, EBV and HHV-6. Posoleucel was one of the first seven investigational therapies to receive both PRIME and RMAT designations and, to AlloVir’s knowledge, is the only investigational therapy to receive three RMAT designations. In addition, the FDA also granted posoleucel Orphan Drug Designation for the treatment of virus-associated HC, and the EMA granted Orphan Medicinal Product designation to posoleucel for its targeted viruses in HCT patients, including for the potential prevention of infections or disease by these viruses.

ALVR106: VST Therapy for the Treatment of Patients with Respiratory Viruses

Acute respiratory tract infections due to respiratory viruses including RSV, influenza, PIV, and hMPV are a major public health concern. For example, RSV-induced bronchiolitis is the most common reason for hospital admission in children less than one year of age. The lack of approved antiviral agents to treat many respiratory viruses underscores the need for alternative treatment and prevention strategies.

ALVR106 is an allogeneic, off-the-shelf VST therapy designed to treat or prevent four common respiratory viruses, RSV, influenza, PIV, and hMPV. A Phase 1/2 proof of concept clinical trial of ALVR106 to target severe respiratory diseases in high-risk populations was initiated in 2022. Part A of the trial completed enrollment, however AlloVir has discontinued this trial pending the outcome of AlloVir’s review of strategic alternatives.

ALVR107: VST Therapy for the Treatment of Hepatitis B Virus

Hepatitis B Virus

The global prevalence of HBV has been estimated to be between 292 and 360 million people with approximately 260 million people living with chronic HBV infection.

Chronic HBV infection is associated not only with significant morbidity and mortality, but also with weak or absent endogenous HBV-specific T-cell reactivity. In contrast, clinical recovery and effective antiviral therapy are associated with sustained viral control by HBV-specific T cells. An off-the-shelf VST therapy that could enable functional cure of HBV would meet a critical unmet medical need.

ALVR107

ALVR107 is an allogeneic, off-the-shelf VST therapy designed to lead to functional cure of patients with HBV. ALVR107 is comprised of a bank of VSTs manufactured from eligible third-party healthy donors who are pre-screened for infectious agents and disease risk factors. These donors are chosen to reflect and accommodate the HLA diversity of the patient population. Preclinical and IND-enabling studies of ALVR107 to treat and cure HBV were completed in 2022 to support advancement into a POC study.

Competition

The biopharmaceutical industry is characterized by rapidly advancing technologies, intense competition and strong emphasis on proprietary products. While AlloVir believes that its innovative and proprietary technology, the expertise of its executive and scientific team, and its access to cell therapy process development and manufacturing expertise at ElevateBio and BaseCamp provide the company with competitive advantages,

AlloVir faces potential competition from many different sources, including pharmaceutical and biotechnology companies, academic institutions and public and private research institutions. VST therapies that AlloVir may successfully develop and commercialize may compete with existing therapies and new therapies that may become available in the future.

Many of AlloVir’s competitors, either alone or with their collaborators, may have a more established presence in the market and significantly greater financial, technical and human resources than it has. The competitors also compete with AlloVir in recruiting and retaining qualified scientific, sales, marketing and management personnel. Smaller or early-stage companies may also prove to be significant competitors through collaborative arrangements with large and established companies.

AlloVir’s commercial potential could be reduced or eliminated if its competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, or are less expensive than any product(s) that AlloVir may develop. AlloVir’s competitors may also obtain FDA or other regulatory approval for their products faster than AlloVir may obtain approval for its product(s), which could result in AlloVir’s competitors establishing a strong market position before AlloVir is able to enter the market or make its development more complicated.

Cell Therapies

There are currently no FDA-approved cell therapies for treating or preventing the viral diseases and infections AlloVir is targeting. Atara Biotherapeutics, Inc.’s Ebvallo™ (tabelecleucel), an off-the-shelf, allogeneic T-cell immunotherapy, for HCT and SOT patients with EBV+PTLD (EBV-associated post-transplant lymphoproliferative disease), received European marketing authorization in December 2022.

Antivirals

There are currently no FDA or EMA-approved antiviral therapies for treating most viral diseases and infections in the post-transplant setting, and current antiviral therapies are associated with significant toxicity, including renal insufficiency and bone marrow suppression. Despite the availability of antivirals for some of the viral diseases AlloVir is targeting, patients continue to experience high levels of morbidity and mortality. Additionally, the effectiveness of these antivirals is limited due to the emergence of drug resistance. Similarly, there are limitations to prophylactic approaches, such as vaccines, which may not work well in immunosuppressed patients, the elderly, and the very young who are unable to mount an effective immune response.

Intellectual Property

AlloVir strives to protect its intellectual property, including by obtaining, maintaining, defending, and enforcing patent protection in the United States and internationally for AlloVir’s proprietary technology, improvements, platforms, product candidates and components thereof, novel biological discoveries, new therapeutic approaches and potential indications, and other inventions that are important to AlloVir’s business. For AlloVir’s product candidates, generally AlloVir initially pursues patent protection covering compositions of matter, methods of production, and methods of use. Throughout the development of its product candidates, AlloVir will seek to identify additional means of obtaining patent protection that would potentially enhance commercial success, including through additional pharmaceutical formulations, methods of use and production.

As of December 31, 2024, AlloVir’s patent portfolio includes ten patent families exclusively in-licensed from Baylor College of Medicine (“BCM”) in AlloVir’s field (one of which is co-owned by AlloVir) and one patent family wholly owned by AlloVir. These families include issued and pending patents related generally to allogeneic, off-the-shelf, single and multi-VST cell therapies, and specifically to posoleucel, ALVR106 and ALVR109, various potential preclinical product candidates including ALVR107 and ALVR108, and clinical and backup processes for generating VST-cell products and banks. Specifically, AlloVir wholly owns two pending PCT applications and exclusively in-licenses at least seven issued U.S. patents, 74 patents issued in foreign jurisdictions, and 71 patent applications pending worldwide. AlloVir’s issued patents are expected to expire between 2030 and 2038, and any patents that may issue from AlloVir’s pending patent applications are expected to expire between 2030 and 2043, absent any patent term adjustments or extensions. As to the patent term extension to restore patent term lost during product development and the FDA regulatory review process, the restoration period cannot be longer than five years and the total patent term including the restoration period must not exceed 14 years following FDA approval.

AlloVir’s portfolio related to posoleucel includes two patent families exclusively in-licensed from BCM, directed to multi-VST compositions and methods of making and using such compositions therapeutically. The first family includes two issued U.S. patents with claims directed to AlloVir’s clinical and backup methods of making multi-VST cell lines and related patent applications are pending in the U.S. and Europe. Patents in this family are expected to expire in 2030, absent any patent term adjustments or extensions. The second family includes one issued U.S. patent with claims directed to methods of making posoleucel, one issued European patent with claims directed to methods of making multi-VST compositions including posoleucel and ALVR106, and a second issued European patent with claims directed to compositions of multi-VST compositions including posoleucel and ALVR106, made via such methods. The first European patent is validated in 19 European states, and the second in 21 European States, each including Denmark, France, Germany, Spain and the United Kingdom (“UK”). Related patent applications are pending in the U.S. and in Europe. Patents in this family are expected to expire in 2033, absent any patent term adjustments or extensions as noted above. AlloVir’s portfolio related to posoleucel also includes one patent family wholly owned by AlloVir with two pending PCT applications directed to doses and dosing regimens for treating BK viremia and BK disease in subjects, including solid organ transplant patients using VST compositions such as posoleucel. As part of AlloVir’s alternative strategic direction, AlloVir has decided not to proceed with nationalizing and prosecuting these PCT applications, and it is expected that they will be abandoned.

AlloVir’s portfolio related to its ALVR106 product candidate includes the two patent families discussed above with respect to posoleucel as well as a patent family directed to the ALVR106 product and methods of making and using the same therapeutically. This patent family includes one U.S. pending patent application and pending patent applications in Australia, Canada, Europe, and Japan. Any patents that may issue from this patent application are expected to expire in 2040, absent any patent term adjustments or extensions. Additionally, AlloVir’s portfolio related to its ALVR106 product candidate includes a patent family with one granted U.S. patent and other applications pending in ex-U.S. jurisdictions with claims directed to VSTs targeting ALVR106 antigens hMPV and PIV. The U.S. patent, and any patents that may issue from the pending patent applications are expected to expire in 2036, absent any patent term adjustments or extensions.

AlloVir’s portfolio licensed from BCM also includes a patent family related to its ALVR109 product candidate and methods of treating COVID-19 and other coronavirus infections using the same. This patent family includes one U.S. pending patent application, and 1 pending patent applications in Europe. Any patents that may issue from the patent applications in this family are expected to expire in 2041, absent any patent term adjustments or extensions.

As part of AlloVir’s alternative strategic direction, AlloVir has decided to abandon its patent family licensed from BCM related to VST compositions, including its ALVR107 and ALVR108 product candidates, and methods of making and using the same therapeutically. The PCT application in this patent family was allowed to expire with no nationalizations filed, and AlloVir presently intends to allow the pending application in Taiwan to passively abandon.

AlloVir’s portfolio further includes other patent families related to its VST technologies. For example, AlloVir’s portfolio includes one patent family that includes one pending patent application in each of the U.S. and Europe related to AlloVir’s process of selecting donors for VST generation and AlloVir’s methods of matching patients with suitable VST-cell lines; one patent family that includes one pending patent application in each of the U.S. and Europe related to methods for the prophylactic treatment of viral infections; one patent family with one issued U.S. patent, five issued foreign patents, and pending patent applications in the U.S. and foreign jurisdictions including Australia, Canada, Europe, and Japan, directed to methods of identifying peptides that are likely to be immunogenic or, as is discussed already above, directed to VSTs targeting ALVR106 antigens hMPV and PIV; one patent family including one pending patent application in each of the U.S. and Europe directed to universal antigen-specific T cells compositions and methods of making and using the same; and one patent family including 12 issued patents (including a European patent validated in 7 European states) and 2 pending patent applications with claims directed to methods of rapidly expanding T-cells. Patents in the T-cell expansion family are expected to expire in 2032, and any patents that may issue from the immunogenicity family, the donor selection family, the methods for prophylactic treatment family, or the universal antigen- specific T cell family are expected to expire in 2036, 2040, 2040, and 2041, respectively, absent any patent term adjustments or extensions.

Individual patents extend for varying periods depending on the date of filing of the patent application or the date of patent issuance and the legal term of patents in the countries in which they are obtained. Generally, patents issued for regularly filed applications in the United States are granted a term of 20 years from the earliest effective non-provisional filing date. In addition, in certain instances, a patent term can be extended to recapture a portion of the U.S. Patent and Trademark Office (the “USPTO”), delay in issuing the patent as well as a portion of the term effectively lost as a result of the FDA regulatory review period. However, as noted, as to the FDA component, the restoration period cannot be longer than five years and the total patent term including the restoration period must not exceed 14 years following FDA approval.

AlloVir also relies on trade secrets relating to product candidates and seek to protect and maintain the confidentiality of proprietary information to protect aspects of its business that are not amenable to, or that it does not consider appropriate for, patent protection. It is AlloVir’s policy to require its employees, consultants, outside scientific partners, sponsored researchers and other advisors to execute confidentiality agreements upon the commencement of employment or consulting relationships with AlloVir. These agreements provide that all confidential information concerning AlloVir’s business or financial affairs developed or made known to the individual during the course of the individual’s relationship with AlloVir is to be kept confidential and not disclosed to third parties except in specific circumstances. AlloVir’s agreements with employees and consultants also provide that all inventions conceived by the employee or consultant in the course of employment or consulting relationships with AlloVir or from the employee’s or consultant’s use of AlloVir’s confidential information are AlloVir’s exclusive property and require such employees and consultants to assign their title, right and interest in such inventions to AlloVir. Although AlloVir takes steps to protect its proprietary information and trade secrets, including through such contractual means with its employees and consultants, third parties may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to AlloVir’s trade secrets, including through breaches of such agreements with AlloVir’s employees and consultants. Thus, AlloVir may not be able to meaningfully protect its trade secrets.

Sponsored Research, Collaboration, License and Other Agreements

Amended and Restated Exclusive License Agreement with BCM

In June 2017, AlloVir signed a License Agreement (the “License Agreement”), with BCM, whereby AlloVir acquired a royalty-bearing, worldwide, exclusive license to BCM’s rights in Subject Technology and related patent rights in the field of viral infection. In May 2020, AlloVir entered into an amended and restated exclusive license agreement (the “A&R License Agreement”), with BCM, pursuant to which AlloVir obtained (a) an exclusive worldwide license, with the right to sublicense, under certain patent rights and other intellectual property rights of BCM, to make, have made, use, market, sell, offer to sell, lease, import and export products in a particular field, except that such license is non-exclusive within a particular subfield, and in addition with respect to certain patent rights such license is limited to two particular subfields, and (b) an exclusive, worldwide sublicense, with the right to further sublicense, under all patent rights and other intellectual property rights that are exclusively licensed to BCM by a certain third party licensor, to make, have made, use, market, sell, offer to sell, lease, import and export products in the same field. AlloVir’s rights are subject to the rights of the U.S. government and certain rights retained by BCM.

Unless earlier terminated, the A&R License Agreement will expire on a country-by-country basis with respect to a product upon the later of (a) the expiration of the last to expire valid claim of a patent or patent application covering such product in such country or (b) 10 years after the first commercial sale of such product in such country. AlloVir may terminate the A&R License Agreement in its entirety at any time for convenience upon a certain number of days’ written notice. BCM may terminate the A&R License Agreement in its entirety for AlloVir’s uncured material default.

BCM maintains control of all filing, prosecution and maintenance of its patent rights licensed by AlloVir, and AlloVir is responsible for all related costs and expenses during the term of the agreement. AlloVir also reimbursed BCM for costs and expenses (including reasonable legal fees and expenses) incurred prior to the effective date of the agreement with respect to the filing, prosecution and maintenance of the patent rights licensed by AlloVir. If BCM licenses the patent rights licensed by AlloVir to third parties for additional fields of use, AlloVir’s responsibility for patent-related costs and expenses will be reduced on a pro-rata basis.

Under the A&R License Agreement, AlloVir must use commercially reasonable efforts to develop and commercialize one or more products in certain countries. As partial consideration for the rights conveyed by BCM under the original agreement executed in June 2017, AlloVir paid BCM a non-refundable license fee of $250,000. During the term of the A&R License Agreement, AlloVir is obligated to pay BCM a non-refundable annual license maintenance fee of $20,000 on the first through fourth anniversaries of the original agreement date and $40,000 beginning on the fifth anniversary of the original agreement date, but beginning with the fifth anniversary of the original agreement date, license maintenance fees are fully creditable against royalty revenue due in the applicable year. AlloVir is required to pay certain milestone payments upon the achievement of specified clinical, regulatory, and sales milestones. In the event that AlloVir is able to successfully develop, launch and commercialize a product under the A&R License Agreement, total milestone payments could exceed $40.0 million. BCM is also eligible to receive tiered royalties at percentage rates ranging from less than 1% to the low single-digits, on net sales of any products that are commercialized by AlloVir or AlloVir’s sublicensees that incorporate, utilize or are made with the use of, the intellectual property licensed by AlloVir. To the extent AlloVir sublicenses its license rights under the A&R License Agreement, BCM would be eligible to receive tiered sublicense income at percentage rates in the mid-single to low double-digits.

In November 2020, AlloVir entered into the First Amendment (the “License Amendment”), to the A&R License Agreement. Under the License Amendment, AlloVir assumed responsibility from BCM for the filing, prosecution and maintenance of the patent rights licensed by AlloVir from BCM under the A&R License Agreement that are in common with the License Agreement. Further, BCM also transferred to AlloVir the right of enforcement against third parties for any suspected infringement of any claims in such patent rights or misuse, misappropriation, theft or breach of confidence of other proprietary rights.

Exclusive License Agreement with BCM

In November 2020, AlloVir signed a second License Agreement (the “Second License Agreement”), with BCM, whereby AlloVir acquired a royalty-bearing, worldwide, exclusive license to BCM’s rights in Subject Technology and related patent rights outside the field of viral infection (all fields other than those covered by the License Agreement Amendment noted above).

Unless earlier terminated, the Second License Agreement will expire on a country-by-country basis with respect to a product upon the later of (a) the expiration of the last to expire valid claim of a patent or patent application covering such product in such country or (b) 10 years after the first commercial sale of such product in such country, provided that the Second License Agreement shall not expire later than March 25, 2040. AlloVir may terminate the Second License Agreement in its entirety at any time for convenience upon a certain number of days’ written notice. BCM may terminate the Second License Agreement in its entirety for AlloVir’s uncured material default.

Under the Second License Agreement, BCM transferred to AlloVir control of all filing, prosecution and maintenance of the patent rights licensed by AlloVir, and AlloVir is responsible for all related costs and expenses during the term of the Second License Agreement. BCM also transferred to AlloVir the right of enforcement against third parties for any suspected infringement of any claims in the patent rights or misuse, misappropriation, theft or breach of confidence of other proprietary rights. AlloVir also reimbursed BCM for costs and expenses (including reasonable legal fees and expenses) incurred prior to the effective date of the Second License Agreement with respect to the filing, prosecution and maintenance of the patent rights licensed by AlloVir, to the extent not already paid by AlloVir under the A&R License Agreement.

Under the Second License Agreement, AlloVir must use commercially reasonable efforts to develop and commercialize one or more products in certain countries. As partial consideration for the rights conveyed by BCM under the Second License Agreement, AlloVir paid BCM a non-refundable license fee of $125,000. During the term of the Second License Agreement, AlloVir is obligated to pay BCM a non-refundable annual license maintenance fee of (a) $20,000 for the first through fourth anniversary of the effective date of the Second License Agreement, and (b) $40,000 for the fifth anniversary of the effective date and continuing thereafter, but beginning with the fifth year, license maintenance fees are fully creditable against royalty revenue due in the applicable year. AlloVir is required to pay certain milestone payments upon the achievement of specified clinical, regulatory, and sales milestones. In the event that AlloVir is able to successfully develop, launch and commercialize multiple products under the Second License Agreement, total milestone payments could exceed $30.0 million. BCM is also eligible to receive tiered royalties at percentage rates ranging from less than 1% to the low single-digits, on net sales of any products that are commercialized by AlloVir or AlloVir’s sublicensees that incorporate, utilize or are made with the use of, the intellectual property licensed by AlloVir. To the extent AlloVir sublicenses its license rights under the Second License Agreement, BCM would be eligible to receive tiered sublicense income at percentage rates in the mid-single to low double-digits.

Collaboration Agreement with BCM

In November 2020, AlloVir entered into a Research Collaboration Agreement (the “Research Agreement”), with BCM, under which AlloVir agreed to pay BCM for performing certain research activities under the direction of Dr. Ann Leen commencing on January 1, 2021, and continuing for a three-year period thereafter. The Research Agreement requires AlloVir to make payments to BCM totaling approximately $6.0 million over the term of the Research Agreement. In August 2023, the term of the Research Agreement was extended for an additional year, expiring December 31, 2024. In March 2024, the term of the Research Agreement was extended to December 31, 2025.

Redeemable Preferred Stock Redemption Agreement

In September 2018, AlloVir entered into a redeemable preferred stock redemption agreement (“Redemption Agreement”), to redeem shares of its Series A1 convertible preferred stock held by certain investors, including executive officer Ann Leen, director and former executive officer Juan Vera and entities affiliated with director, Malcolm Brenner and former director, John Wilson (or their affiliates). Pursuant to the Redemption Agreement, for a period of 20 years from the date of the first commercial sale of Viralym-M by AlloVir, AlloVir is obligated to make earnout payments to such investors on at least an annual basis. The earnout payments will be 10% of AlloVir’s net sales of Viralym-M, which number will be reduced to a high single-digit percentage if certain events occur. Specifically, royalties due to third parties for the sale of Viralym-M are subtracted from the earnout payments due to the investors. Further, if the investors receive at least $50,000,000 in earnout payments from AlloVir during the three-year period after the first commercial sale of Viralym-M, the earnout payment percentage will be reduced.

CPRIT Grant

In August 2017, AlloVir was awarded a grant (the “CPRIT Grant”) from the Cancer Prevention and Research Institute of Texas (“CPRIT”). The CPRIT Grant required that AlloVir grant CPRIT a non-commercial license to technology developed under the grant and pay CPRIT a share of revenue on sales of commercial products developed using CPRIT funds equal to low single digits of revenue until such time as CPRIT has been paid an aggregate amount equal to 400% of the grant award proceeds.

Manufacturing

AlloVir’s versatile VST manufacturing platform supports the rapid, robust and scalable generation of single- and multi-virus specific cell therapeutic candidates for clinical use. AlloVir leverages Cytokin™, its proprietary algorithm to select donors from whom to generate VSTs such that there is broad patient HLA coverage through an efficient set of donors. Virus-specific T-cells from individual healthy seropositive donors are expanded in a fully good manufacturing practices (“cGMP”), compliant process, which is scaled to produce hundreds of patient doses from each manufacturing run. AlloVir’s VST cell therapies are maintained in a cryopreserved state ready for “off-the-shelf” use. Cytomatch™, AlloVir’s proprietary algorithm for HLA matching, identifies the best VST cell line for each patient. In combination, these elements allow AlloVir to efficiently build its global supply chain to serve patients who could benefit from its highly innovative off-the-shelf VST therapy candidates.

Government Regulation

In the United States, biological products, are subject to regulation under the Federal Food, Drug, and Cosmetic Act (“FD&C Act”), and the Public Health Service Act (“PHS Act”), and other federal, state, local and foreign statutes and regulations. Both the FD&C Act and the PHS Act and their corresponding regulations govern, among other things, the research, development, clinical trial, testing, manufacturing, quality control, safety, efficacy, labeling, packaging, storage, record keeping, distribution, reporting, marketing, promotion, advertising, post-approval monitoring, and post-approval reporting involving biological products. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources, and AlloVir may not be able to obtain the required regulatory approvals.

U.S. Biological Products Development Process

The process required by the FDA before a biological product may be marketed in the United States generally involves the following:

•

completion of nonclinical laboratory tests and animal studies according to good laboratory practices (“GLPs”) and applicable requirements for the humane use of laboratory animals or other applicable regulations;

•

submission to the FDA of an application for an investigational new drug application (“IND”) which must become effective before human clinical trials may begin;

•

approval of the protocol and related documentation by an independent institutional review board (“IRB”) or ethics committee at each clinical trial site before each study may be initiated;

•

performance of adequate and well-controlled human clinical trials according to the FDA’s regulations commonly referred to as good clinical practices (“GCPs”), and any additional requirements for the protection of human research subjects and their health information, to establish the safety and efficacy of the proposed biological product for its intended use;

•

preparation of and submission to the FDA of a biologics license application (“BLA”) for marketing approval that includes sufficient evidence of establishing the efficacy, safety, purity, and potency of the proposed biological product for its intended indication, including from results of nonclinical testing and clinical trials;

•

satisfactory completion of an FDA inspection of the manufacturing facility or facilities where the biological product is produced to assess compliance with current good manufacturing practices (“cGMPs”) to assure that the facilities, methods and controls are adequate to preserve the biological product’s identity, strength, quality and purity and, if applicable, the FDA’s current good tissue practices (“cGTPs”) for human cellular and tissue products;

•

potential FDA audit of the nonclinical study and clinical trial sites that generated the data in support of the BLA;

•

review of the product candidate by an FDA advisory committee, where appropriate and if applicable;

•

payment of user fees for FDA review of the BLA (unless a fee waiver applies); and

•

FDA review and approval of the BLA, resulting in the licensure of the biological product for commercial marketing.

Before testing any biological product candidate, in humans, the product candidate enters the preclinical testing stage. Preclinical tests, also referred to as nonclinical studies, may include laboratory evaluations of product biological characteristics, chemistry, toxicity and formulation, as well as animal studies to assess the potential safety and activity of the product candidate. The conduct of the preclinical tests must comply with federal regulations and requirements including GLPs, if applicable.

Prior to beginning the first clinical trial with a product candidate in the United States, an IND must be submitted to the FDA and the FDA must allow the IND to proceed. An IND is an exemption from the FD&C Act that allows an unapproved product candidate to be shipped in interstate commerce for use in an investigational clinical trial and a request for FDA allowance that such investigational product may be administered to humans in connection with such trial. Such authorization must be secured prior to interstate shipment and administration. In support of a request for an IND, applicants must submit a protocol for each clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IND. In addition, the results of the preclinical tests, together with manufacturing information, analytical data, any available clinical data or literature and plans for clinical trials, among other things, must be submitted to the FDA as part of an IND. An IND must become effective before human clinical trials may begin. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the 30-day time period, raises safety concerns or questions about the proposed clinical trial. In such a case, the IND may be placed on clinical hold or partial clinical hold. In this case, the IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can begin. Submission of an IND therefore may or may not result in FDA allowance to begin a clinical trial.

In addition to the submission of an IND to the FDA before initiation of a clinical trial in the United States, certain human clinical trials involving recombinant or synthetic nucleic acid molecules are subject to oversight of institutional biosafety committees (“IBCs”), as set forth in the National Institutes of Health (“NIH”) Guidelines for Research Involving Recombinant or Synthetic Nucleic Acid Molecules (“NIH Guidelines”). Under the NIH Guidelines, recombinant and synthetic nucleic acids are defined as: (i) molecules that are constructed by joining nucleic acid molecules and that can replicate in a living cell (i.e., recombinant nucleic acids); (ii) nucleic acid molecules that are chemically or by other means synthesized or amplified, including those that are chemically or otherwise modified but can base pair with naturally occurring nucleic acid molecules (i.e., synthetic nucleic acids); or (iii) molecules that result from the replication of those described in (i) or (ii). Specifically, under the NIH Guidelines, supervision of human gene transfer trials includes evaluation and assessment by an IBC, a local institutional committee that reviews and oversees research utilizing recombinant or synthetic nucleic acid molecules at that institution. The IBC assesses the safety of the research and identifies any potential risk to public health or the environment, and such review may result in some delay before initiation of a clinical trial. While the NIH Guidelines are not mandatory unless the research in question is being conducted at or sponsored by institutions receiving NIH funding of recombinant or synthetic nucleic acid molecule research, many companies and other institutions not otherwise subject to the NIH Guidelines voluntarily follow them.

Clinical trials involve the administration of the biological product candidate to healthy volunteers or patients under the supervision of qualified investigators who generally are physicians not employed by, or under, the control of, the trial sponsor. Clinical trials are conducted under written study protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria and the parameters to be used to monitor subject safety, including stopping rules that assure a clinical trial will be stopped if certain adverse events should occur.

An IRB representing each institution participating in the clinical trial must review and approve the plan for any clinical trial before it commences at that institution, and the IRB must conduct continuing review and reapprove the study at least annually. The IRB must review and approve, among other things, the study protocol and informed consent information to be provided to study subjects. An IRB must operate in compliance with FDA regulations. An IRB can suspend or terminate approval of a clinical trial at its institution, or an institution it represents, if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the product candidate has been associated with unexpected serious harm to patients.

Some trials are overseen by an independent group of qualified experts organized by the trial sponsor, known as a data safety monitoring board or committee (“DSMB”). This group provides authorization as to whether or not a trial may move forward at designated check points based on data from the ongoing study that are available to the DSMB members.

Certain information about certain clinical trials must also be submitted within specific timeframes to the NIH for public dissemination on its ClinicalTrials.gov website.

Clinical trials typically are conducted in three sequential phases that may overlap or be combined:

•

Phase 1. The investigational product is initially introduced into healthy human subjects and tested for safety. In the case of some products for severe or life-threatening diseases, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.

•

Phase 2. The investigational product is evaluated in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance, optimal dosage and dosing schedule.

•

Phase 3. The investigational product is administered to an expanded patient population to further evaluate dosage, clinical efficacy, potency, and safety in an expanded patient population at geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit ratio of the product and provide an adequate basis for approval and product labeling.

In some cases, FDA may require, or firms may voluntarily pursue, post-approval clinical trials, sometimes referred to as Phase 4 clinical trials, after initial marketing approval. These clinical trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication, particularly for long- term safety follow-up. During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data, and clinical trial investigators. Annual progress reports detailing the results of the clinical trials must be submitted to the FDA. Written IND safety reports must be promptly submitted to the FDA and the investigators for serious and unexpected adverse events, any findings from other studies, tests in laboratory animals or in vitro testing that suggest a significant risk for human subjects, or any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. The sponsor must submit an IND safety report within 15 calendar days after the sponsor determines that the information qualifies for reporting. The sponsor also must notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction within seven calendar days after the sponsor’s initial receipt of the information. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. The FDA or the sponsor, acting on its own or based on a recommendation from the sponsor’s data safety monitoring board, may suspend a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the biological product has been associated with unexpected serious harm to patients.

Concurrent with clinical trials, companies may complete additional animal studies and also must develop additional information about the physical characteristics of the biological product as well as finalize a process for manufacturing the product in commercial quantities in accordance with cGMP and as applicable cGTP requirements. To help reduce the risk of the introduction of adventitious agents with use of biological products, the PHS Act emphasizes the importance of manufacturing control for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the sponsor must develop methods for testing the identity, strength, quality, potency and purity of the final biological product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the biological product candidate does not undergo unacceptable deterioration over its shelf life.

U.S. Review and Approval Processes

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, the results of product development, nonclinical studies and clinical trials are submitted to the FDA as part of a BLA requesting approval to market the product for one or more indications. The BLA must include results of product development, laboratory and animal studies, human studies, information on the manufacture and composition of the product, proposed labeling and other relevant information.

Within 60 days following submission of the application, the FDA reviews a BLA submitted to determine if it is substantially complete before the FDA accepts it for filing. The FDA may refuse to file any BLA that it deems incomplete or not properly reviewable at the time of submission and may request additional information. In this event, the BLA must be resubmitted with the additional information. The resubmitted application also is subject to review to determine if it is substantially complete before the FDA accepts it for filing. In most cases, the submission of a BLA is subject to a substantial application user fee, although the fee may be waived under certain circumstances. Under the performance goals and policies implemented by the FDA under the Prescription Drug User Fee Act (“PDUFA”) for original BLAs, the FDA targets ten months from the date FDA files the application (i.e., the filing date) in which to complete its initial review of a standard application and respond to the applicant, and six months from the filing date for an application granted priority review by FDA. The FDA does not always meet its PDUFA goal dates, and the review process is often significantly extended by FDA requests for additional information or clarification.

Once the submission is accepted for filing, the FDA begins an in-depth substantive review of the BLA. The FDA reviews the BLA to determine, among other things, whether the proposed product is safe, pure and potent, for its intended use, and whether the product is being manufactured in accordance with cGMP to ensure its continued safety, purity and potency. The FDA may refer applications for novel biological products or biological products that present difficult or novel questions of safety, efficacy, or quality to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. During the biological product approval process, the FDA also will determine whether a Risk Evaluation and Mitigation Strategy (“REMS”), is necessary to assure the safe use of the biological product. If the FDA concludes a REMS is needed, the sponsor of the BLA must submit a proposed REMS; the FDA will not approve the BLA without a REMS, if required.

Before approving a BLA, the FDA typically will inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Where applicable, the FDA also will not approve the product if the manufacturer is not in compliance with the cGTPs. These are FDA regulations that govern the methods used in, and the facilities and controls used for, the manufacture of human cells, tissues, and cellular and tissue-based products (“HCT/Ps”), which are human cells or tissue intended for implantation, transplant, infusion, or transfer into a human patient. The primary intent of the CGTP requirements is to ensure that cell and tissue-based products are manufactured in a manner designed to prevent the introduction, transmission and spread of communicable disease. FDA regulations also require tissue establishments to register and list their HCT/Ps with the FDA and, when applicable, to evaluate donors through appropriate screening and testing. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical sites to assure that the clinical trials were conducted in compliance with IND study requirements and GCP requirements. To ensure cGMP, cGTP and GCP compliance, an applicant must incur significant expenditure of time, money and effort in the areas of training, record keeping, production and quality control.

Under the Pediatric Research Equity Act (“PREA”), a BLA or supplement to a BLA for a novel product (e.g., new active ingredient, new indication, etc.) must contain data to assess the safety and effectiveness of the biological product for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDA may grant deferrals for submission of data or full or partial waivers. Unless otherwise required by regulation, PREA does not apply to any biological product for an indication for which orphan designation has been granted.

After the FDA evaluates a BLA and conducts inspections of manufacturing facilities where the investigational product and/or its drug substance will be produced, the FDA may issue an approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications. A Complete Response Letter will describe all of the deficiencies that the FDA has identified in the BLA, except that where the FDA determines that the data supporting the application are inadequate to support approval, the FDA may issue the Complete Response Letter without first conducting required inspections, testing submitted product lots, and/or reviewing proposed labeling. In issuing the Complete Response Letter, the FDA may recommend actions that the applicant might take to place the BLA in condition for approval, including requests for additional information or clarification. The FDA may delay or refuse approval of a BLA if applicable regulatory criteria are not satisfied, require additional testing or information and/ or require post-marketing testing and surveillance to monitor safety or efficacy of a product.

If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, including to subpopulations of patients, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings precautions or interactions be included in the product labeling. The FDA may impose restrictions and conditions on product distribution, prescribing, or dispensing in the form of a REMS, or otherwise limit the scope of any approval. The FDA also may condition approval on, among other things, changes to proposed labeling or the development of adequate controls and specifications. Once approved, the FDA may withdraw the product approval if compliance with pre- and post-marketing requirements is not maintained or if problems occur after the product reaches the marketplace. The FDA may require one or more Phase IV post-market studies and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization, and may limit further marketing of the product based on the results of these post-marketing studies.

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biological product intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States and for which there is no reasonable expectation that the cost of developing and making a drug or biological product available in the United States for this type of disease or condition will be recovered from sales of the product. Orphan product designation must be requested before submitting a BLA. After the FDA grants orphan product designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan product designation does not convey any advantage in or shorten the duration of the regulatory review and approval process.

If a product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the disease for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications, including a full BLA, to market the same biologic for the same indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity or if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or the same drug or biologic for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver of the BLA application user fee.

A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. In addition, orphan drug exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or, as noted above, if the second applicant demonstrates that its product is clinically superior to the approved product with orphan exclusivity or the manufacturer of the approved product is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition.

Orphan drug designation may also entitle a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers.

Expedited Development and Review Programs

The FDA has various programs, including Fast Track designation, breakthrough therapy designation, accelerated approval and priority review, that are intended to expedite or simplify the process for the development and FDA review of drugs and biologics that are intended for the treatment of serious or life-threatening diseases or conditions. To be eligible for fast track designation, new drugs and biological product candidates must be intended to treat a serious or life-threatening condition and demonstrate the potential to address unmet medical needs for the condition. Fast Track designation applies to the combination of the product and the specific indication for which it is being studied. The sponsor of a new drug or biologic may request the FDA to designate the drug or biologic as a fast track product at any time during the clinical development of the product. One benefit of fast track designation, for example, is that the FDA may consider for review sections of the marketing application on a rolling basis before the complete application is submitted if certain conditions are satisfied, including an agreement with the FDA on the proposed schedule for submission of portions of the application and the payment of applicable user fees before the FDA may initiate a review.

Under the FDA’s breakthrough therapy program, a sponsor may seek FDA designation of its product candidate as a breakthrough therapy if the product candidate is intended, alone or in combination with one or more other drugs or biologics, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that it may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Breakthrough therapy designation comes with all of the benefits of fast track designation, which means that the sponsor may file sections of the BLA for review on a rolling basis if certain conditions are satisfied, including an agreement with the FDA on the proposed schedule for submission of portions of the application and the payment of applicable user fees before the FDA may initiate a review. The FDA may take other actions appropriate to expedite the development and review of the product candidate, including holding meetings with the sponsor and providing timely advice to, and interactive communication with, the sponsor regarding the development program.

A product candidate is eligible for priority review if it treats a serious or life-threatening disease or condition and, if approved, would provide a significant improvement in the safety or effectiveness of the treatment, diagnosis or prevention of a serious disease or condition. The FDA will attempt to direct additional resources to the evaluation of an application for a new drug or biological product designated for priority review in an effort to facilitate the review. Under priority review, the FDA’s goal is to review an application in six months once it is filed, compared to ten months for a standard review. Priority review designation does not change the scientific/medical standard for approval or the quality of evidence necessary to support approval.

Additionally, a product candidate may be eligible for accelerated approval. Drug or biological products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic benefit over existing treatments may receive accelerated approval, which means that they may be approved on the basis of adequate and well-controlled clinical trials establishing that the product has an effect on a surrogate endpoint that is reasonably likely to predict a clinical benefit, or on the basis of an effect on an intermediate clinical endpoint other than survival or irreversible morbidity, taking into account the severity, rarity, or prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA generally requires that a sponsor of a drug or biological product receiving accelerated approval perform adequate and well-controlled post-marketing clinical trials with due diligence and, under the Food and Drug Omnibus Reform Act of 2022 (“FDORA”), the FDA is now permitted to require, as appropriate, that such trials be underway prior to approval or within a specific time period after the date of approval for a product granted accelerated approval. In addition, for products being considered for accelerated approval, unless otherwise informed by the FDA, the FDA generally requires, that all advertising and promotional materials intended for dissemination or publication within 120 days following marketing approval be submitted to the agency for review during the pre-approval review period, and that after 120 days following marketing approval, all advertising and promotional materials must be submitted at least 30 days prior to the intended time of initial dissemination or publication. Under FDORA, the FDA has increased authority for expedited procedures to withdraw approval of a drug or indication approved under accelerated approval if, for example, the confirmatory trial fails to verify the predicted clinical benefit of the product.

RMAT Designation

As part of the 21st Century Cures Act, enacted in December 2016, Congress created the Regenerative Medicine Advanced Therapy, designation to facilitate an efficient development program for, and expedite review of, a product candidate that meets the following criteria: (1) it qualifies as a RMAT, which is defined as a cell therapy, therapeutic tissue engineering product, human cell and tissue product, or any combination product using such therapies or products, with limited exceptions; (2) it is intended to treat, modify, reverse, or cure a serious or life- threatening disease or condition; and (3) preliminary clinical evidence indicates that the drug has the potential to address unmet medical needs for such a disease or condition. A sponsor may request that the FDA designate a drug as a RMAT concurrently with or at any time after submission of an IND. The FDA has 60 calendar days to determine whether the drug meets the criteria. A BLA for a regenerative medicine therapy that has received RMAT designation may be eligible for priority review or accelerated approval through use of surrogate or intermediate endpoints reasonably likely to predict long-term clinical benefit, or reliance upon data obtained from a meaningful number of sites. Benefits of RMAT designation also include early interactions with FDA to discuss any potential surrogate or intermediate endpoint to be used to support accelerated approval. A regenerative medicine therapy with RMAT designation that is granted accelerated approval and is subject to post-approval requirements may, as appropriate, fulfill such requirements through the submission of clinical evidence from clinical trials, patient registries, or other sources of real world evidence, such as electronic health records; the collection of larger confirmatory data sets; or post-approval monitoring of all patients treated with such therapy prior to its approval. Like some of FDA’s other expedited development programs, RMAT designation does not change the standards for approval but may help expedite the development or approval process.

Post-approval Requirements

Rigorous and extensive FDA regulation of biological products continues after approval, particularly with respect to cGMP requirements, as well as requirements relating to record-keeping, reporting of adverse experiences, periodic reporting, product sampling and distribution, and advertising and promotion of the product. AlloVir currently relies, and may continue to rely, on third parties for the production of clinical and commercial quantities of any products that AlloVir may commercialize. Manufacturers of AlloVir’s products are required to comply with applicable requirements in the cGMP regulations, including quality control and quality assurance and maintenance of records and documentation. Other post-approval requirements applicable to biological products, include reporting of cGMP deviations that may affect the identity, potency, purity and overall safety of a distributed product, record-keeping requirements, reporting of adverse effects, reporting updated safety and efficacy information, and complying with electronic record and signature requirements. As part of the manufacturing process, the manufacturer is required to perform certain tests on each lot of the product before it is released for distribution. After a BLA is approved for a biological product, the product also may be subject to official lot release. If the product is subject to official release by the FDA, the manufacturer submits samples of each lot of product to the FDA together with a release protocol showing a summary of the history of manufacture of the lot and the results of all of the manufacturer’s tests performed on the lot. The FDA also may perform certain confirmatory tests on lots of some products before releasing the lots for distribution by the manufacturer. In addition, the FDA conducts laboratory research related to the regulatory standards on the safety, purity, potency, and effectiveness of biological products.

Manufacturers also must comply with the FDA’s advertising and promotion requirements, such as those related to direct-to-consumer advertising, the prohibition on promoting products for uses or in patient populations that are not described in the product’s approved labeling (known as “off-label use”), industry-sponsored scientific and educational activities, and promotional activities involving the internet. Discovery of previously unknown problems or the failure to comply with the applicable regulatory requirements may result in restrictions on the marketing of a product or withdrawal of the product from the market as well as possible civil or criminal sanctions.

Failure to comply with the applicable United States requirements at any time during the product development process, approval process or after approval, may subject an applicant or manufacturer to administrative or judicial civil or criminal sanctions and adverse publicity. FDA sanctions could include refusal to approve pending applications, withdrawal of an approval, clinical holds, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, product detentions or refusal to permit the import or export of the product, restrictions on the marketing or manufacturing of the product, injunctions, fines, refusals of government contracts, mandated corrective advertising or communications with doctors or other stakeholders, debarment, restitution, disgorgement of profits, or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us.

Biological product manufacturers and other entities involved in the manufacture and distribution of approved biological products, and those supplying products, ingredients, and components of them, are required to register their establishments with the FDA and certain state agencies, and they are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. Manufacturers and other parties involved in the drug supply chain for prescription drug products must also comply with product tracking and tracing requirements and for notifying the FDA of counterfeit, diverted, stolen and intentionally adulterated products or products that are otherwise unfit for distribution in the United States. Additionally, discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved BLA, including withdrawal of the product from the market. In addition, changes to the manufacturing process or facility generally require prior FDA approval before being implemented and other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

Marketing Exclusivity

A patent claiming a new biological product may be eligible for a limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, which permits a patent restoration of up to five years for patent term lost during product development and FDA regulatory review. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the effective date of an IND and the submission date of a BLA plus the time between the submission date of a BLA and the approval of that application. Only one patent applicable to an approved biological product is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. In addition, a patent can only be extended once and only for a single product. The USPTO, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration.

The Affordable Care Act (“ACA”), signed into law on March 23, 2010, includes a subtitle called the Biologics Price Competition and Innovation Act of 2009 (“BPCIA”), which created an abbreviated approval pathway for biological products shown to be biosimilar to, or interchangeable with, an FDA-licensed reference biological product. This amendment to the PHS Act attempts to minimize duplicative testing. Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of safety, purity, and potency, can be shown through analytical studies, animal studies, and a clinical trial or trials. Interchangeability requires that a product is biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product and, for products administered multiple times, the biologic and the reference biologic may be switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic.

FDA will not accept an application for a biosimilar or interchangeable product based on the reference biological product until four years after the date of first licensure of the reference product, and FDA will not approve an application for a biosimilar or interchangeable product based on the reference biological product until twelve years after the date of first licensure of the reference product. “First licensure” typically means the initial date the particular product at issue was licensed in the United States. Date of first licensure does not include the date of licensure of (and a new period of exclusivity is not available for) a biological product if the licensure is for a supplement for the biological product or for a subsequent application by the same sponsor or manufacturer of the biological product (or licensor, predecessor in interest, or other related entity) for a change (not including a modification to the structure of the biological product) that results in a new indication, route of administration, dosing schedule, dosage form, delivery system, delivery device or strength, or for a modification to the structure of the biological product that does not result in a change in safety, purity, or potency.

The BPCIA is complex and continues to be interpreted and implemented by the FDA. In addition, government proposals have sought to reduce the 12-year reference product exclusivity period. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate impact, implementation, and impact of the BPCIA is subject to significant uncertainty.

In addition to exclusivity under the BPCIA, a biological product can obtain pediatric market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing exclusivity periods for all formulations, dosage forms, and indications of the active moiety. This six-month exclusivity, which runs from the end of other exclusivity protection, may be granted based on the voluntary completion of a pediatric study in accordance with an FDA-issued “Written Request” for such a study, provided that at the time pediatric exclusivity is granted there is not less than nine months of term remaining.

U.S. Foreign Corrupt Practices Act, U.K. Bribery Act and Other Laws

The U.S. Foreign Corrupt Practices Act of 1977 (“FCPA”) prohibits United States corporations and individuals from engaging in certain activities to obtain or retain business or secure any improper advantage, or to influence a person working in an official capacity. It is illegal to pay, offer to pay or authorize the payment of anything of value to any employee or official of a foreign government or public international organization, or political party, political party official, or political candidate in an attempt to obtain or retain business or to otherwise influence a person working in an official capacity. The scope of the FCPA also includes employees and officials of state- owned or controlled enterprises, which may include healthcare professionals in many countries. Equivalent laws have been adopted in other foreign countries that impose similar obligations.

Our operations are also subject to non-United States anti-corruption laws such as the U.K. Bribery Act 2010, or (the “Bribery Act”). As with the FCPA, these laws generally prohibit AlloVir and its employees and intermediaries from authorizing, promising, offering, or providing, directly or indirectly, improper or prohibited payments, or anything else of value, to government officials or other persons to obtain or retain business or gain some other business advantage. Under the Bribery Act, AlloVir may also be liable for failing to prevent a person associated with AlloVir from committing a bribery offense.

AlloVir is also subject to other laws and regulations governing AlloVir’s international operations, including regulations administered by the governments of the United Kingdom and the United States and authorities in the European Union, including applicable export control regulations, economic sanctions and embargoes on certain countries and persons, anti-money laundering laws, import and customs requirements and currency exchange regulations, collectively referred to as trade control laws.

Failure to comply with the Bribery Act, the FCPA and other anti-corruption laws and trade control laws could subject AlloVir to criminal and civil penalties, disgorgement and other sanctions and remedial measures, and legal expenses.

Government Regulation Outside of the United States

In addition to regulations in the United States, AlloVir is subject to a variety of regulations in other jurisdictions governing, among other things, research and development, clinical trials, testing, manufacturing, safety, efficacy, labeling, packaging, storage, record keeping, distribution, reporting, advertising and other promotional practices involving biological products as well as authorization and approval of AlloVir’s products. Because biologically sourced raw materials are subject to unique contamination risks, their use may be restricted in some countries.

The requirements and processes governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. In all cases, the clinical trials must be conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

If AlloVir fails to comply with applicable foreign regulatory requirements, AlloVir may be subject to, among other things, fines, suspension of clinical trials, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Clinical Trials Regulation

Approvals from regulatory authorities in foreign countries are required prior to the commencement of clinical trials or marketing of the product in those countries. Certain countries outside of the United States have a similar process that requires the submission of a clinical trial application much like the IND prior to the commencement of human clinical trials. In the European Union, for example, a Clinical Trial Application (“CTA”) must be submitted for each clinical trial to each country’s National Competent Authority (“NCA”) and at least one independent Ethics Committee (“EC”), much like the FDA and an IRB, respectively. Once the CTA is approved in accordance with a country’s requirements, the corresponding clinical trial may proceed. Under the current regime (the EU Clinical Trials Directive 2001/20/EC and corresponding national laws) all suspected unexpected serious adverse reactions to the investigational drug that occur during the clinical trial have to be reported to the NCA and ECs of the European Union Member State where they occurred.

In April 2014, the European Union adopted a new Clinical Trials Regulation (EU) No 536/2014, which is set to replace the current Clinical Trials Directive 2001/20/EC. It will overhaul the current system of approvals for clinical trials in the European Union.

Specifically, the new Clinical Trials Regulation, which will be directly applicable in all Member States (meaning that no national implementing legislation in each European Union Member State is required), aims at simplifying and streamlining the approval of clinical trials in the European Union. For instance, the new Clinical Trials Regulation provides for a streamlined application procedure via a single entry point and strictly defined deadlines for the assessment of clinical trial applications. It is expected that the new Clinical Trials Regulation will come into effect following confirmation of full functionality of the Clinical Trials Information System, the centralized European Union portal and database for clinical trials foreseen by the new Clinical Trials regulation, through an independent audit, which is currently expected to occur in January 2023.

Drug Review and Approval

In the European Economic Area (comprised of the European Union Member States plus Norway, Iceland and Liechtenstein) (“EEA”), medicinal products, including advanced therapy medicinal products (“ATMPs”), are subject to extensive pre- and post-market regulation by regulatory authorities at both the EEA and national levels. Under Article 2(1) of Regulation (EC) No 1394/2007 (“the ATMP Regulation”) ATMPs comprise gene therapy products, somatic cell therapy products and tissue engineered products. Somatic cell therapy products comprise cells that have undergone substantial manipulation so that biological characteristics, physiological functions or structural properties relevant for the intended clinical use have been altered, where such cells are to be administered to human beings in order to cure, diagnose or prevent disease. AlloVir believes that its current products are somatic cell therapy medical products which would be regulated as ATMPs in the EEA.

To obtain regulatory approval of ATMP in the EEA, a marketing authorization application (“MAA”) must be submitted under the centralized procedure administered by the European Medicines Agency (“EMA”). The centralized procedure provides for the grant of a single marketing authorization by the European Commission that is valid across all of the EEA. As provided for in the ATMP Regulation, the scientific evaluation of MAAs for ATMPs is primarily performed by a specialized scientific committee called the Committee for Advanced Therapies (“CAT”). The CAT prepares a draft opinion on the quality, safety and efficacy of the ATMP which is the subject of the MAA, which is sent for final approval to the Committee for Medicinal Products for Human Use. The CHMP recommendation is then sent to the European Commission, which adopts a decision binding in all EEA Member States. The maximum timeframe for the evaluation of an MAA for an ATMP is 210 days from receipt of a valid MAA, excluding clock stops when additional information or written or oral explanation is to be provided by the applicant in response to questions of the CAT and/or CHMP. Clock stops may extend the timeframe of evaluation of a MAA considerably beyond 210 days. Where the CHMP gives a positive opinion, the EMA provides the opinion together with supporting documentation to the European Commission, who make the final decision to grant a marketing authorization, which is issued within 67 days of receipt of the EMA’s recommendation. Accelerated assessment may be granted by the CHMP in exceptional cases, when a medicinal product is of major interest from the point of view of public health and, in particular, from the viewpoint of therapeutic innovation. If the CHMP accepts such a request, the timeframe of 210 days for assessment will be reduced to 150 days (excluding clock stops), but it is possible that the CHMP may revert to the standard time limit for the centralized procedure if it determines that the application is no longer appropriate to conduct an accelerated assessment.

The application used to submit the BLA in the United States is similar to that required in the European Union, with the exception of, among other things, certain specific requirements set out in the ATMP Regulation, for example certain particulars to be contained in the summary of product characteristics. A MAA holder for an ATMP in Europe must also put in place a system to ensure that each individual product, and its starting and raw materials, can be traced through the sourcing, manufacturing, packaging, storage, transport and delivery to the relevant healthcare institution.

Now that the UK (which comprises Great Britain and Northern Ireland) has left the European Union, Great Britain will no longer be covered by centralized marketing authorizations (under the Northern Irish Protocol, centralized marketing authorizations will continue to be recognized in Northern Ireland). All medicinal products with a current centralized marketing authorization were automatically converted to Great Britain marketing authorizations on January, 1 2021. For a period of two years from January 1, 2021, the Medicines and Healthcare products Regulatory Agency (“MHRA”), the UK medicines regulator, may rely on a decision taken by the European Commission on the approval of a new marketing authorization in the centralized procedure, to more quickly grant a new Great Britain marketing authorization. A separate application will, however, still be required.

Data and Marketing Exclusivity

The EEA also provides opportunities for market exclusivity. Upon receiving a marketing authorization in the EEA, innovative medicinal products generally receive eight years of data exclusivity and an additional two years of market exclusivity. If granted, data exclusivity prevents generic or biosimilar applicants from referencing the innovator’s preclinical or clinical trial data contained in the dossier of the reference product when applying for a generic or biosimilar marketing authorization during a period of eight years from the date on which the reference product was first authorized in the EEA. During the additional two-year period of market exclusivity, a generic or biosimilar marketing authorization can be submitted, and the innovator’s data may be referenced, but no generic or biosimilar product can be marketed until the expiration of the market exclusivity period. The overall ten-year period will be extended to a maximum of eleven years if, during the first eight years of those ten years, the marketing authorization holder obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to authorization, is held to bring a significant clinical benefit in comparison with existing therapies. Even if an innovative medicinal product gains the prescribed period of data exclusivity, another company may market another version of the product if such company obtained marketing authorization based on a MAA with a complete independent data package of pharmaceutical tests, preclinical tests and clinical trials.

Orphan Drug Designation and Exclusivity

Products with an orphan designation in the EEA can receive ten years of market exclusivity, during which time “no similar medicinal product” for the same indication may be placed on the market. A “similar medicinal product” is defined as a medicinal product containing a similar active substance or substances as contained in an authorized orphan medicinal product, and which is intended for the same therapeutic indication. An orphan product can also obtain an additional two years of market exclusivity in the European Union where an agreed Pediatric Investigation Plan for pediatric studies has been complied with. No extension to any supplementary protection certificate can be granted on the basis of pediatric studies for orphan indications.

The criteria for designating an “orphan medicinal product” in the European Union are similar in principle to those in the United States. Under Article 3 of Regulation (EC) 141/2000, a medicinal product may be designated as an orphan medicinal product if it meets the following criteria: (1) it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; (2) either the prevalence of such condition must not be more than five in 10,000 persons in the European Union when the application is made, or without the benefits derived from orphan status, it must be unlikely that the marketing of the medicine would generate sufficient return in the EEA to justify the investment needed for its development; and (3) there exists no satisfactory method of diagnosis, prevention or treatment of such condition authorized for marketing in the EEA, or if such a method exists, the product will be of significant benefit to those affected by the condition, as defined in Regulation (EC) 847/2000. Orphan medicinal products are eligible for financial incentives such as reduction of fees or fee waivers and are, upon grant of a marketing authorization, entitled to ten years of market exclusivity for the approved therapeutic indication. The application for orphan drug designation must be submitted before the application for marketing authorization. The applicant will receive a fee reduction for the MAA if the orphan drug designation has been granted, but not if the designation is still pending at the time the marketing authorization is submitted. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

The ten year market exclusivity may be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for orphan designation, for example, if the product is sufficiently profitable not to justify maintenance of market exclusivity. Otherwise, orphan medicine marketing exclusivity may be revoked only in very select cases, such as if:

•

it is established that a similar medicinal product is safer, more effective or otherwise clinically superior;

•

the marketing authorization holder consents to a second orphan medicinal product application; or

•

the marketing authorization holder cannot supply enough orphan medicinal product.

From January 1, 2021, a separate process for orphan drug designation will apply in Great Britain. There will be no pre-marketing authorization orphan designation (as there is in the EEA) and the application for orphan designation will be reviewed by the MHRA at the time of the marketing authorization application. The criteria are the same as in the EEA, save that they apply to Great Britain only (e.g. there must be no satisfactory method of diagnosis, prevention or treatment of the condition concerned in Great Britain).

Pediatric Development

In the EEA, companies developing a new medicinal product must agree upon a Pediatric Investigation Plan (“PIP”) with the EMA’s Pediatric Committee (“PDCO”) and must conduct pediatric clinical trials in accordance with that PIP, unless a waiver applies, (e.g., because the relevant disease or condition occurs only in adults). The PIP sets out the timing and measures proposed to generate data to support a pediatric indication of the drug for which marketing authorization is being sought. The marketing authorization application for the product must include the results of pediatric clinical trials conducted in accordance with the PIP, unless a waiver applies, or a deferral has been granted by the PDCO of the obligation to implement some or all of the measures of the PIP until there are sufficient data to demonstrate the efficacy and safety of the product in adults, in which case the pediatric clinical trials must be completed at a later date. Products that are granted a marketing authorization with the results of pediatric clinical trials conducted in accordance with the PIP are eligible for a six month extension of the protection under a supplementary protection certificate (if any is in effect at the time of approval) even where the trial results are negative. In the case of orphan medicinal products, a two year extension of the orphan market exclusivity. This pediatric reward is subject to specific conditions and is not automatically available when data in compliance with the PIP are developed and submitted.

PRIME Designation

In March 2016, the EMA launched an initiative to facilitate development of product candidates in indications, often rare, for which few or no therapies currently exist. The PRIME scheme is intended to encourage drug development in areas of unmet medical need and provides accelerated assessment of products representing substantial innovation, where the marketing authorization application will be made through the centralized procedure. Eligible products must target conditions for which where is an unmet medical need (there is no satisfactory method of diagnosis, prevention or treatment in the EEA or, if there is, the new medicine will bring a major therapeutic advantage) and they must demonstrate the potential to address the unmet medical need by introducing new methods of therapy or improving existing ones. Products from small- and medium-sized enterprises may qualify for earlier entry into the PRIME scheme than larger companies. Many benefits accrue to sponsors of product candidates with PRIME designation, including but not limited to, early and proactive regulatory dialogue with the EMA, frequent discussions on clinical trial designs and other development program elements, and accelerated marketing authorization application assessment once a dossier has been submitted. Importantly, a dedicated Agency contact and rapporteur from the Committee for Human Medicinal Products (“CHMP”) or Committee for Advanced Therapies are appointed early in PRIME scheme facilitating increased understanding of the product at EMA’s Committee level. A kick-off meeting initiates these relationships and includes a team of multidisciplinary experts at the EMA to provide guidance on the overall development and regulatory strategies. Where, during the course of development, a medicine no longer meets the eligibility criteria, support under the PRIME scheme may be withdrawn.

Post-Approval Controls

Following approval, the holder of the marketing authorization is required to comply with a range of requirements applicable to the manufacturing, marketing, promotion and sale of the medicinal product. These include the following:

•

The holder of a marketing authorization must establish and maintain a pharmacovigilance system and appoint an individual qualified person for pharmacovigilance, who is responsible for oversight of that system. Key obligations include expedited reporting of suspected serious adverse reactions and submission of periodic safety update reports (“PSURs”).

•

All new MAAs must include a risk management plan describing the risk management system that the company will put in place and documenting measures to prevent or minimize the risks associated with the product. The regulatory authorities may also impose specific obligations as a condition of the marketing authorization. Such risk-minimization measures or post-authorization obligations may include additional safety monitoring, more frequent submission of PSURs, or the conduct of additional clinical trials or post-authorization safety studies. RMPs and PSURs are routinely available to third parties requesting access, subject to limited redactions.

•

All advertising and promotional activities for the product must be consistent with the approved SmPC and therefore all off-label promotion is prohibited. Direct-to-consumer advertising of prescription medicines is also prohibited in the European Union. Although general requirements for advertising and promotion of medicinal products are established under European Union directives, the details are governed by regulations in each European Union Member State and can differ from one country to another.

Brexit and the Regulatory Framework in the United Kingdom

In June 2016, the electorate in the United Kingdom voted in favor of leaving the European Union (commonly referred to as “Brexit”). Thereafter, in March 2017, the country formally notified the European Union of its intention to withdraw pursuant to Article 50 of the Lisbon Treaty. The United Kingdom formally left the European Union on January 31, 2020. A transition period began on February 1, 2020, during which European Union pharmaceutical law remained applicable to the United Kingdom, and ended on December 31, 2020. Since the regulatory framework for pharmaceutical products in the United Kingdom covering quality, safety and efficacy of pharmaceutical products, clinical trials, marketing authorization, commercial sales and distribution of pharmaceutical products is derived from European Union Directives and Regulations, Brexit could materially impact the future regulatory regime which applies to products and the approval of product candidates in the United Kingdom, as the United Kingdom legislation now has the potential to diverge from European Union legislation. It remains to be seen how Brexit will impact regulatory requirements for product candidates and products in the United Kingdom in the long term. The MHRA has recently published detailed guidance for industry and organizations to follow now the transition period is over, which will be updated as the United Kingdom’s regulatory position on medicinal products and medical devices evolves over time.

Coverage and Reimbursement

Sales of AlloVir’s products would depend, in part, on the extent to which AlloVir’s products would be covered by third-party payors, such as government health programs, commercial insurance and managed healthcare organizations. In the U.S., no uniform policy of coverage and reimbursement for drug or biological products exists. Accordingly, decisions regarding the extent of coverage and amount of reimbursement to be provided for any of AlloVir’s products would be made on a payor-by-payor basis. The process for determining whether a third-party payor will provide coverage for a product may be separate from the process for setting the price or reimbursement rate that the payor will pay for the product once coverage is approved. Third-party payors are increasingly challenging the prices charged, examining the medical necessity, and reviewing the cost- effectiveness of medical products and services and imposing controls to manage costs. The coverage determination process is often a time-consuming and costly process that would require AlloVir to provide scientific and clinical support for the use of its products to each payor separately, with no assurance that coverage and adequate reimbursement would be obtained.

In the United States and in other countries, patients generally rely on third-party payors to reimburse all or part of the costs associated with their treatment. Adequate coverage and reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and commercial payors is critical to new product acceptance. The ability to successfully commercialize product candidates depends in part on the extent to which coverage and adequate reimbursement for these products and related treatments are available from government health administration authorities, private health insurers and other organizations. Government authorities and other third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. The availability of coverage and extent of reimbursement by governmental and private payors is essential for most patients to be able to afford treatments such as cell or gene therapy products. Sales of these or other product candidates will depend substantially, both domestically and abroad, on the extent to which the costs will be paid by health maintenance, managed care, and similar healthcare management organizations, or reimbursed by government health administration authorities, private health coverage insurers and other third-party payors. If coverage and adequate reimbursement are not available, or are available only to limited levels successful commercialization may be difficult. Even if coverage is provided, the approved reimbursement amount may not be high enough to establish or maintain pricing sufficient to realize a sufficient return on its investment. For products administered under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs. Additionally, separate reimbursement for the product itself or the treatment or procedure in which the product is used may not be available, which may impact physician utilization.

There is also significant uncertainty related to the insurance coverage and reimbursement of newly approved products and coverage may be more limited than the purposes for which the medicine is approved by the FDA or comparable foreign regulatory authorities. In the United States, the principal decisions about reimbursement for new medicines are typically made by the Centers for Medicare & Medicaid Services (“CMS”) an agency within the U.S. Department of Health and Human Services (“HHS”). CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare, and private payors tend to follow CMS to a substantial degree. Factors a payor considers in determining reimbursement are based on whether the product is:

•

a covered benefit under its health plan;

•

safe, effective and medically necessary;

•

appropriate for the specific patient;

•

cost-effective; and

•

neither experimental nor investigational.

Net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States.

Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. Reimbursement is not guaranteed for any product candidate that is commercialized.

In addition, many pharmaceutical manufacturers must calculate and report certain price reporting metrics to the government, such as average sales price (“ASP”) and best price. Penalties may apply in some cases when such metrics are not submitted accurately and timely. Further, these prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs.

Many third-party payors are increasingly limiting both coverage and the level of reimbursement of new drugs. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. Many pharmaceutical manufacturers must calculate and report certain price reporting metrics to the government, such as ASP, and best price.

Further, these prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States.

In addition, in some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing vary widely from country to country. For example, the European Union provides options for its Member States to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost effectiveness of a particular product candidate to currently available therapies. A Member State may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements. Historically, products launched in the European Union do not follow price structures of the U.S. and generally prices tend to be significantly lower.

Other Healthcare Laws and Compliance Requirements

In the United States, AlloVir’s current and future operations are subject to regulation by various federal, state and local authorities in addition to the FDA, including but not limited to, CMS, other divisions of the HHS, (such as the Office of Inspector General, Office for Civil Rights and the Health Resources and Service Administration), the U.S. Department of Justice (“DOJ”) and individual U.S. Attorney offices within the DOJ, and state and local governments. AlloVir’s clinical research, sales, marketing and scientific/educational grant programs may be subject to the following laws, each as amended, as applicable:

•

the federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully soliciting, receiving, offering or paying any remuneration (including any kickback, bribe, or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce, or in return for, either the referral of an individual, or the purchase, lease, order, arrangement or recommendation of any good, facility, item or service for which payment may be made, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs; a person or entity does not need to have actual knowledge of the federal Anti-Kickback Statute or specific intent to violate it to have committed a violation. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand, and prescribers, purchasers and formulary managers, among others, on the other. Violations are subject to civil and criminal fines and penalties for each violation, plus up to three times the remuneration involved, imprisonment, and exclusion from government healthcare programs. In addition, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False Claims Act or federal civil money penalties statute;

•

the federal civil and criminal false claims laws and civil monetary penalty laws, including the False Claims Act, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, false or fraudulent claims for payment to, or approval by, Medicare, Medicaid, or other federal healthcare programs, knowingly making, using or causing to be made or used a false record or statement material to a false or fraudulent claim or obligation to pay or transmit money or property to the federal government, or knowingly concealing or knowingly and improperly avoiding or decreasing or concealing an obligation to pay money to the federal government. A claim that includes items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim under the False Claims Act. Manufacturers can be held liable under the False Claims Act even when they do not submit claims directly to government payors if they are deemed to “cause” the submission of false or fraudulent claims. The False Claims Act also permits a private individual acting as a “whistleblower” to bring actions on behalf of the federal government alleging violations of the False Claims Act and to share in any monetary recovery;

•

the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) which created additional federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g., public or private) and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false, fictitious, or fraudulent statements or representations in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

•

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 (“HITECH”) and their respective implementing regulations, including the Final Omnibus Rule published in January 2013, which impose requirements on certain covered healthcare providers, health plans, and healthcare clearinghouses as well as their respective business associates that perform services for them that involve the use, or disclosure of, individually identifiable health information, relating to the privacy, security and transmission of individually identifiable health information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, there may be additional federal, state and non-U.S. laws which govern the privacy and security of health and other personal information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts;

•

the federal transparency requirements under the ACA, including the provision commonly referred to as the Physician Payments Sunshine Act, and its implementing regulations, which require applicable manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to CMS, information related to payments or other transfers of value made to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), certain other licensed healthcare practitioners and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members;

•

federal government price reporting laws, which require AlloVir to calculate and report complex pricing metrics in an accurate and timely manner to government programs;

•

federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers; and

•

analogous state and foreign law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any third-party payor, including commercial insurers or patients; state laws that require pharmaceutical companies to comply with the industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare providers and other potential referral sources; state and local laws that require the licensure of pharmaceutical sales representatives; state laws that require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures and pricing information; and state and foreign laws that govern the privacy and security of health information in some circumstances. These data privacy and security laws may differ from each other in significant ways and often are not pre-empted by HIPAA, which may complicate compliance efforts.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of AlloVir’s business activities could be subject to challenge under one or more of such laws.

Government enforcement agencies have shown increased interest in pharmaceutical companies’ product and patient assistance programs, including reimbursement support services, and a number of investigations into these programs have resulted in significant civil and criminal settlements. In addition, at least one insurer has directed its network pharmacies to no longer accept co-pay coupons for certain specialty drugs the insurer identified. In addition, in November 2013, the CMS issued guidance to the issuers of qualified health plans sold through the ACA’s marketplaces encouraging such plans to reject patient cost-sharing support from third parties and indicating that the CMS intends to monitor the provision of such support and may take regulatory action to limit it in the future. The CMS subsequently issued a rule requiring individual market qualified health plans to accept third-party premium and cost-sharing payments from certain government-related entities. In September 2014, the OIG of the HHS issued a Special Advisory Bulletin warning manufacturers that they may be subject to sanctions under the federal Anti-Kickback Statute and/or civil monetary penalty laws if they do not take appropriate steps to exclude Part D beneficiaries from using co-pay coupons. Accordingly, companies exclude these Part D beneficiaries from using co-pay coupons. It is possible that changes in insurer policies regarding co-pay coupons and/or the introduction and enactment of new legislation or regulatory action could restrict or otherwise negatively affect these patient support programs, which could result in fewer patients using affected products, and therefore could have a material adverse effect on AlloVir’s sales, business, and financial condition.

Third party patient assistance programs that receive financial support from companies have become the subject of enhanced government and regulatory scrutiny. The OIG has established guidelines that suggest that it is lawful for pharmaceutical manufacturers to make donations to charitable organizations who provide co-pay assistance to Medicare patients, provided that such organizations, among other things, are bona fide charities, are entirely independent of and not controlled by the manufacturer, provide aid to applicants on a first-come basis according to consistent financial criteria and do not link aid to use of a donor’s product. However, donations to patient assistance programs have received some negative publicity and have been the subject of multiple government enforcement actions, related to allegations regarding their use to promote branded pharmaceutical products over other less costly alternatives. Specifically, in recent years, there have been multiple settlements resulting out of government claims challenging the legality of their patient assistance programs under a variety of federal and state laws. It is possible that AlloVir may make grants to independent charitable foundations that help financially needy patients with their premium, co-pay, and co-insurance obligations. If AlloVir chooses to do so, and if AlloVir or its vendors or donation recipients are deemed to fail to comply with relevant laws, regulations or evolving government guidance in the operation of these programs, AlloVir could be subject to damages, fines, penalties, or other criminal, civil, or administrative sanctions or enforcement actions. AlloVir cannot ensure that its compliance controls, policies, and procedures will be sufficient to protect against acts of its employees, business partners, or vendors that may violate the laws or regulations of the jurisdictions in which AlloVir operates. Regardless of whether AlloVir has complied with the law, a government investigation could impact AlloVir’s business practices, harm its reputation, divert the attention of management, increase its expenses, and reduce the availability of foundation support for its patients who need assistance.

On December 2, 2020, HHS published a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers (PBMs), unless the price reduction is required by law. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a safe harbor for certain fixed fee arrangements between PBMs and manufacturers. Implementation of this change and new safe harbors for point-of-sale reductions in price for prescription pharmaceutical products and PBM service fees are currently under review by the current U.S. presidential administration and may be amended or repealed. Although a number of these and other proposed measures may require authorization through additional legislation to become effective, and the current U.S. presidential administration may reverse or otherwise change these measures, both the current U.S. presidential administration and Congress have indicated that they will continue to seek new legislative measures to control drug costs.

Law enforcement authorities are increasingly focused on enforcing fraud and abuse laws, and it is possible that some of AlloVir’s practices may be challenged under these laws. Efforts to ensure that AlloVir’s current and future business arrangements with third parties, and AlloVir’s business generally, will comply with applicable healthcare laws and regulations will involve substantial costs. If AlloVir’s operations, including its arrangements with physicians and other healthcare providers, are found to be in violation of any of such laws or any other governmental regulations that apply to it, AlloVir may be subject to penalties, including, without limitation, administrative, criminal and/or civil penalties, damages, fines, disgorgement, reputational harm, imprisonment, the exclusion or suspension from federal and state healthcare programs such as Medicare and Medicaid and debarment from contracting with the United States government, and/or the curtailment or restructuring of AlloVir’s operations, as well as additional reporting obligations and oversight if AlloVir becomes subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws. If any of the physicians or other healthcare providers or entities with whom AlloVir expects to do business are found to be not in compliance with applicable laws, they may be subject to similar penalties.

The risk of AlloVir’s being found in violation of these laws is increased by the fact that many of these laws have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Any action against AlloVir for violation of these laws, even if AlloVir successfully defends against it, could cause AlloVir to incur significant legal expenses and divert its management’s attention from the operation of its business. The shifting compliance environment and the need to build and maintain a robust system to comply with multiple jurisdictions with different compliance and reporting requirements increases the possibility that a healthcare company may violate one or more of the requirements. Efforts to ensure that AlloVir’s business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial cost.

Data Privacy and Security Laws

AlloVir may also be subject to data privacy and security laws in the United States and various jurisdictions around the world in which AlloVir operates or from which AlloVir collects or otherwise processes personally identifiable information, or personal information. In the United States, HIPAA, imposes privacy, security and breach reporting obligations with respect to individually identifiable health information upon “covered entities” (health plans, health care clearinghouses and certain health care providers), and their respective business associates, individuals or entities that create, received, maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity. HIPAA mandates the reporting of certain breaches of personal information to HHS, affected individuals and if the breach is large enough, the media. Entities that are found to be in violation of HIPAA as the result of a breach of unsecured protected health information, a complaint about privacy practices or an audit by HHS, may be subject to significant civil, criminal and administrative fines and penalties and/or additional reporting and oversight obligations if required to enter into a resolution agreement and corrective action plan with HHS to settle allegations of HIPAA non-compliance. Even when HIPAA does not apply, according to the Federal Trade Commission or the FTC, failing to take appropriate steps to keep consumers’ personal information secure constitutes unfair acts or practices in or affecting commerce in violation of Section 5(a) of the Federal Trade Commission Act (“the FTCA”) 15 U.S.C § 45(a). The FTC expects a company’s data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities. Individually identifiable health information is considered sensitive data that merits stronger safeguards.

Regulators and legislators in the U.S. are also increasingly scrutinizing and restricting certain personal data transfers and transactions involving foreign countries. For example, the Biden Administration’s executive order Preventing Access to Americans’ Bulk Sensitive Personal Data and United States Government-Related Data by Countries of Concern as implemented by Department of Justice regulations issued in December 2024, prohibits data brokerage transactions involving certain sensitive personal data categories, including health data, genetic data, and biospecimens, to countries of concern, including China. The regulations also restrict certain investment agreements, employment agreements and vendor agreements involving such data and countries of concern, absent specified cybersecurity controls. Actual or alleged violations of these regulations may be punishable by criminal and/or civil sanctions, and may result in exclusion from participation in federal and state programs.

In addition, certain states govern the privacy and security of health information and/or other personally identifiable information, some of which are more stringent than HIPAA and many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts. Failure to comply with these laws, where applicable, can result in the imposition of significant civil and/or criminal penalties and private litigation. For example, California recently enacted the California Consumer Privacy Act (“CCPA”) which created comprehensive individual privacy rights for California consumers (as defined in the law) and placed increased privacy and security obligations on entities handling personal data of consumers or households. The CCPA required covered companies to provide certain disclosures to consumers about its data collection, use and sharing practices, and to provide affected California residents with ways to opt-out of certain sales or transfers of personal information. While there is currently an exception for protected health information that is subject to HIPAA and/or that is collected, used, or disclosed in clinical trial research, as currently written, the CCPA may still impact AlloVir’s business activities. The uncertainty and enforcement surrounding the implementation of CCPA exemplifies the vulnerability of AlloVir’s business to the evolving regulatory environment related to personal data and protected health information. The CCPA may increase AlloVir’s compliance costs and potential liability. The CCPA marks the beginning of a trend toward more stringent privacy legislation in the U.S., which could increase AlloVir’s potential liability and adversely affect its business.

Additionally, the CCPA was amended by the California Privacy Rights Act (“CPRA”) which as of January 1, 2023 has imposed additional obligations on companies covered by the legislation. The CPRA significantly modified the CCPA, including by expanding consumers’ rights with respect to certain sensitive personal information. The CPRA also created a new state agency that will be vested with authority to implement and enforce the CCPA and the CPRA. The effects of the CCPA, as modified by the CPRA are potentially significant and may require AlloVir to modify its data collection or processing practices and policies and to incur substantial costs and expenses in an effort to comply and increase AlloVir’s potential exposure to regulatory enforcement and/or litigation.

Similar laws have been passed in numerous other states and other states have proposed similar new privacy laws. Such proposed legislation, if enacted, may add additional complexity, variation in requirements, restrictions and potential legal risk, require additional investment of resources in compliance programs, impact strategies and the availability of previously useful data and could result in increased compliance costs and/or changes in business practices and policies. The existence of comprehensive privacy laws in different states in the country would make AlloVir’s compliance obligations more complex and costly and may increase the likelihood that AlloVir may be subject to enforcement actions or otherwise incur liability for noncompliance. There are also states that are specifically regulating health information. For example, Washington’s My Health My Data Act, which became effective on March 31, 2024, regulates the collection and sharing of health information, and the law also has a private right of action, which further increases the relevant compliance risk. Connecticut and Nevada have also passed similar laws regulating consumer health data. In addition, other states have proposed and/or passed legislation that regulates the privacy and/or security of certain specific types of information. For example, a small number of states have passed laws that regulate biometric data specifically. These various privacy and security laws may impact AlloVir’s business activities, including AlloVir’s identification of research subjects, relationships with business partners and ultimately the marketing and distribution of AlloVir’s products. State laws are changing rapidly and there has been discussion in the U.S. Congress of a comprehensive federal data privacy law to which AlloVir could become subject, if enacted.

The collection, use, storage, disclosure, transfer, or other processing of personal information regarding individuals in the European Economic Area, or EEA, including personal health data, is subject to the EU GDPR, which became effective on May 25, 2018. Following Brexit, the EU GDPR has been incorporated into UK laws (“UK GDPR” and together with the EU GDPR, “GDPR”). The GDPR is wide-ranging in scope and imposes numerous requirements on companies that process personal data, including requirements relating to processing of special categories of data (such as health data), where required obtaining consent of the individuals to whom the personal data relates, providing information to individuals regarding data processing activities, implementing safeguards to protect the security and confidentiality of personal data, providing notification of data breaches, conducting data protection impact assessments for high risk processing activities and taking certain measures when engaging third-party processors. The GDPR also imposes strict rules on the transfer of personal data to countries outside the European Union and the UK, including the United States, and permits data protection authorities to impose large penalties for violations of the GDPR, including potential fines of up to €20 million (£17.5 million) or 4% of annual global revenues, whichever is greater. The GDPR also confers a private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek judicial remedies, and obtain compensation for damages resulting from violations of the GDPR. Despite Brexit, the EU and UK GDPR remain largely aligned. Currently, the most impactful point of divergence relates to transfer mechanisms (i.e., the ability for EU/UK companies to transfer personal information to third countries, including the United States), because it requires AlloVir to implement a variety of different contractual clauses approved by EU or UK regulators. This complexity and the additional contractual burden increase AlloVir’s overall risk exposure.

There may be further divergence in the future, including with regard to administrative burdens. The UK government has confirmed that transfers of personal information from the UK to the EEA remain free flowing. The UK Government introduced the Data Protection and Digital Information Bill failed in the UK legislative process. A new Data (Use and Access) Bill (“UK Bill”) has been introduced into parliament. If passed, the final version of the UK Bill may have the effect of further altering the similarities between the UK and EEA data protection regime and threaten the UK adequacy decision from the European Commission. The respective provisions and enforcement of the EU GDPR and UK GDPR may further diverge in the future and create additional regulatory challenges and uncertainties.

In the EEA, the NIS 2 Directive (“NIS 2”) is replacing the cybersecurity legal framework under the current NIS framework, aiming to ensure a high level of cybersecurity in the region. NIS 2 brings new medium and large organisations providing services in the EEA within scope of the legal framework. It extends to additional sectors and expands the list of in-scope healthcare organisations, including to certain providers engaged in research and development of medicinal products. The new regime imposes direct obligations on management in respect of an in-scope organization's compliance with NIS 2, requires covered organisations to put in place certain cyber risk management measures, strengthens incident reporting requirements and provides supervisory authorities with a greater oversight. The majority of obligations will come into force when national legislation implementing NIS 2 becomes effective in the relevant EU Member State. EU Member States had until 17 October 2024 to transpose NIS 2 into national legislation, although many countries have still not completed the transposition. As such, the cybersecurity regulatory landscape in the EU is currently fragmented and uncertain. To the extent AlloVir is subject to NIS 2, AlloVir will require additional investment of our resources in compliance programs. Under NIS 2 companies may be subject to administrative fines of up to the higher amount of €10 million or 2% of worldwide turnover.

Additionally, AlloVir does business around the world and many other foreign jurisdictions have passed data privacy and security legislation and others are considering various proposals for new and/or amended privacy and data protection laws. Complying with these laws, if enacted, would require significant resources and leave AlloVir vulnerable to possible fines and penalties if AlloVir is unable to comply. The regulatory framework governing the collection, processing, storage, use and sharing of certain information is rapidly evolving and is likely to continue to be subject to uncertainty and varying interpretations. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with AlloVir’s existing data management practices or the features of AlloVir’s services and platform capabilities. Any failure or perceived failure by AlloVir, or any third parties with which AlloVir does business, to comply with AlloVir’s posted privacy policies, evolving laws, rules and regulations, industry standards, or contractual obligations to which AlloVir or such third parties are or may become subject, may result in actions or other claims against AlloVir by governmental entities or private actors, the expenditure of substantial costs, time and other resources or the incurrence of significant fines, penalties or other liabilities. In addition, any such action, particularly to the extent AlloVir were found to be guilty of violations or otherwise liable for damages, would damage AlloVir’s reputation and adversely affect its business, financial condition and results of operations.

Healthcare Reform

In the United States and some foreign jurisdictions, there have been, and likely will continue to be, a number of legislative and regulatory changes and proposed changes regarding the healthcare system directed at broadening the availability of healthcare, improving the quality of healthcare, and containing or lowering the cost of healthcare. For example, in 2010, the ACA was enacted which includes changes to the coverage and payment for products under government health care programs. Among other things, the ACA:

•

increases the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program;

•

extends the Medicaid Drug Rebate Program to utilization of prescriptions of individuals enrolled in Medicaid managed care plans;

•

establishes annual fees and taxes on manufacturers of certain branded prescription drugs;

•

creates a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.; and

•

expands the entities eligible for discounts under the PHS Act’s pharmaceutical pricing program, also known as the 340B Drug Pricing Program.

Other legislative changes have been proposed and adopted in the United States since the Affordable Care Act was enacted. The Budget Control Act of 2011, among other things, included aggregate reductions to Medicare payments to providers of 2% per fiscal year. These reductions went into effect on April 1, 2013, and, due to legislation amendments to the statute, including the Bipartisan Budget Act of 2018, will stay in effect through 2031, unless additional Congressional action is taken. On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. In December 2018, CMS published a final rule permitting further collections and payments to and from certain ACA qualified health plans and health insurance issuers under the ACA risk adjustment program in response to the outcome of the federal district court litigation regarding the method CMS uses to determine this risk adjustment. Since then, the ACA risk adjustment program payment parameters have been updated annually. In addition, CMS published a final rule that would give states greater flexibility, as of 2020, in setting benchmarks for insurers in the individual and small group marketplaces, which may have the effect of relaxing the essential health benefits required under the ACA for plans sold through such marketplaces. Further, on May 30, 2018, the Right to Try Act was signed into law. The law, among other things, provides a federal framework for certain patients to request access to certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right to Try Act.

On March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law, which eliminated the statutory Medicaid drug rebate cap, set at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024. These laws and regulations may result in additional reductions in Medicare and other healthcare funding and otherwise affect the prices AlloVir may obtain for any of our product candidates for which AlloVir may obtain regulatory approval or the frequency with which any such product candidate is prescribed or used.

Additionally, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, there have been several recent U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs.

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. Additional legislative changes may be enacted or the FDA or foreign regulations, guidance or interpretations may be changed which could impact the ability to obtain regulatory approvals. In the U.S., the European Union and other potentially significant markets, government authorities and third-party payors are increasingly attempting to limit or regulate the price of medical products and services, particularly for new and innovative products and therapies, which has resulted in lower average selling prices for certain products in certain markets. For example, in the U.S., there have been several recent Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. At a federal level, President Trump reversed some of President Biden’s executive orders including rescinding Executive Order 14087 entitled “Lowering Prescription Drug Costs for Americans”. President Trump may issue new executive orders designed to impact drug pricing. A number of these and other proposed measures may require authorization through additional legislation to become effective. Congress and the Trump administration have indicated that they will continue to seek new legislative measures to control drug costs.

In August 2022, the IRA was signed into law. The IRA includes several provisions that could impact AlloVir’s business to varying degrees, including provisions that create a $2,000 out-of-pocket cap for Medicare Part D beneficiaries, impose new manufacturer financial liability on all drugs in Medicare Part D, allow the U.S. government to negotiate Medicare Part B and Part D pricing for certain high-cost drugs and biologics without generic or biosimilar competition, require companies to pay rebates to Medicare for drug prices that increase faster than inflation, and delay the rebate rule that would require pass through of pharmacy benefit manager rebates to beneficiaries. Further, under the IRA, orphan drugs are exempted from the Medicare drug price negotiation program, but only if they have one orphan designation and for which the only approved indication is for that disease or condition. If a product receives multiple orphan designations or has multiple approved indications, it may not qualify for the orphan drug exemption. The implementation of the IRA is currently subject to ongoing litigation challenging the constitutionality of the IRA’s Medicare drug price negotiation program. The effect of IRA on AlloVir’s business and the healthcare industry in general is not yet known. AlloVir expects that additional U.S. federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that the U.S. Federal Government will pay for healthcare drugs and services, which could result in additional pricing pressures.

At the state level, legislatures are increasingly passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third-party payors or other restrictions could harm AlloVir’s business, financial condition, results of operations and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for AlloVir’s drugs or put pressure on AlloVir’s drug pricing, which could negatively affect AlloVir’s business, financial condition, results of operations and prospects.

Human Capital

As of December 31, 2024, AlloVir had 6 full-time employees. None of AlloVir’s employees are represented by labor unions or covered by collective bargaining agreements. AlloVir considers its relationship with AlloVir’s employees to be good.

AlloVir’s human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating its existing and new employees, advisors and consultants. The principal purposes of AlloVir’s equity incentive plans are to attract, retain and reward personnel through the granting of equity-based compensation awards in order to increase shareholder value and the success of the company by motivating such individuals to perform to the best of their abilities and achieve AlloVir’s objectives.
