Current report

Additionally, we are currently conducting and may in the future conduct clinical trials that utilize an “open-label” trial design. An “open-label” clinical trial is one where both the patient and investigator know whether the patient is receiving the investigational therapeutic candidate (as opposed to an existing approved drug or placebo). Open-label trials typically test only the investigational therapeutic candidate and sometimes may do so at different dose levels. For example, our ongoing Phase I/II clinical trial of AMT-130 is designed as an open-label trial following a 12-month core study period during which certain patients received a sham surgical procedure. Certain of these patients have crossed over to treatment and are now subject to long-term, unblinded follow-up monitoring for a period of five years. Open-label trials are subject to various limitations that may bias the interpretation of the data. Open-label trials may be subject to a “patient bias” where patients perceive their symptoms to have improved merely due to their awareness of receiving an experimental treatment. In addition, open-label trials may be subject to an “investigator bias” where those assessing and reviewing the physiological outcomes of the clinical trials are aware of which patients have received treatment and may interpret the information of the treated group more favorably given this knowledge. Accordingly, the results from our open-label trials, including early indications of potential efficacy, may not be predictive of future clinical trial results.

of surrogate endpoints, which may be utilized due to the challenges inherent in designing and conducting clinical trials for severe diseases that progress slowly and that affect small patient populations. For example, in the course of our interactions with the FDA and EMA, the regulatory authorities may disagree with our interpretation of the interim safety and efficacy data we have received to date, including our determinations of statistical significance and the utility of post hoc analyses we conduct with respect to interim clinical data. Since AMT-130 is based on our novel gene therapy technology, we are unable to predict how regulatory authorities will interpret our data or whether they will agree with our interim conclusions or trial design or whether those data may be utilized in later-stage or registrational trials. We may be required by such regulatory authorities to conduct additional randomized studies of AMT-130 beyond our existing planned clinical trials, which would be costly and would significantly delay the potential approval of AMT-130. We may not be able to commit sufficient capital to support additional clinical studies of AMT-130, in which case we may need to secure a development partner for AMT-130. Such partnerships may not be available, in which case we may not be able to fully fund the AMT-130 program through to regulatory approval.

Current wording

There are numerous factors that could impede or otherwise negatively impact our further development of AMT-130, including, but not limited to, patient safety issues, our failure to demonstrate sufficient clinical efficacy or durability of response data to warrant further development, delays in our ability to enroll patients or challenges with potential development partners, clinical trials or regulatory authorities. Any one or combination of these factors could force us to halt or discontinue the ongoing clinical trials of AMT-130. Certain of these risk factors are heightened in the context of drug development for rare diseases like Huntington’s disease and novel investigational products like gene therapies in which non-traditional study designs are utilized to demonstrate efficacy and safety, including open-label studies, single arm studies, studies utilizing active comparators or natural history data, biomarkers or other forms of surrogate endpoints, which may be utilized due to the challenges inherent in designing and conducting clinical trials for severe diseases that progress slowly and that affect small patient populations. For example, in the course of our interactions with the FDA and EMA, the regulatory authorities may disagree with our interpretation of the interim safety and efficacy data we have received to date, including our determinations of statistical significance and the utility of post hoc analyses we conduct with respect to interim clinical data.

An element of our strategy is to use our gene therapy technology platform to expand our product pipeline and to progress our product candidates through preclinical and clinical development ourselves or together with collaborators. To date, we have only been successful in obtaining regulatory approval for one product, HEMGENIX®, our gene therapy for the treatment of hemophilia B, which was approved for commercialization by the FDA and the EMA in November 2022 and February 2023, respectively. AMT-130 is our investigational gene therapy candidate for the treatment of Huntington’s disease that utilizes our proprietary, gene-silencing miQURE platform and incorporates an AAV vector carrying a miRNA specifically designed to silence the huntingtin gene and the potentially highly toxic exon 1 protein fragment, which is currently in ongoing Phase I/II studies in the U.S. and Europe. In addition to AMT-130, we are also developing other investigational gene therapies, including AMT-260 for the treatment of MTLE, AMT-162 for the treatment of SOD1 ALS and AMT-191 for the treatment of Fabry’s disease. Although we currently have a pipeline of programs at various stages of development, including an approved product, we may not be able to identify or develop product candidates that are safe and effective. Even if we are successful in continuing to build our pipeline, the potential product candidates that we identify may not be suitable for clinical development.

As discussed further under “Recent Business Developments—Lexington Transaction”, in June 2024 we entered into the APA with Genezen pursuant to which we agreed to sell to Genezen and Genezen agreed to purchase certain assets and assume certain liabilities related to the Lexington Facility and our prior manufacturing operations in Lexington, Massachusetts. Pursuant to the APA, Genezen agreed to acquire the manufacturing equipment and related manufacturing operations along with certain other assets associated with the Lexington Facility and to extend offers of employment to a majority of the uniQure employees located at the Lexington Facility. The Lexington Transaction closed on July 22, 2024.

Previous wording

In connection with the closing of the Lexington Transaction, we and Genezen entered into certain additional agreements, including (i) a commercial supply agreement pursuant to which Genezen will manufacture and supply for our requirements of HEMGENIX® pursuant to our manufacturing and supply obligations to CSL Behring, (ii) a development and other manufacturing services agreement pursuant to which Genezen will manufacture, supply and provide certain development services to support the requirements of our investigational gene therapy programs and for other services related to the manufacture of HEMGEMIX®, (iii) a transition services agreement pursuant to which each party will provide transitional services to the other related to the operation of the Lexington Facility for a period following the closing of the Lexington Transaction, and (iv) an assignment and assumption of the lease agreement for the Lexington Facility, along with other customary agreements. As a component of our broader efforts to focus our business and reduce operating expenses, the Lexington Transaction is expected to reduce our cash burn as a result of a reduction in facility and personnel-related costs, among others. The Lexington Transaction may not ultimately reduce our operating expenses to a magnitude consistent with our expectations. In addition, we may be exposed to additional costs and risks related to or as a result of the Lexington Transaction, including, without limitation (i) additional expenses associated with outsourcing certain manufacturing and development services, as well as our contractual obligations and minimum financial commitments to Genezen under the CSA and the DMSA, (ii) supply-related risks related Genezen’s ability and capacity to satisfy our continued obligations to CSL Behring and the supply of our other product candidates, including AMT-130, (iii) contractual default under our agreements with Genezen or with CSL Behring, and (iv) other third-party risks relative to our partnership with Genezen (see “—Risk Related to our Reliance on Third Parties). The occurrence of any of the foregoing or any other risks as a result of or related to the Lexington Transaction could considerably harm our business and impact our financial condition and results of operations.

Our proprietary manufacturing process leveraging insect cells and baculoviruses to produce to AAV-based gene therapies is highly complex and is regularly subject to variation or production difficulties. Issues with any of our manufacturing processes, even minor deviations from our standard processes, could result in insufficient yield, product deficiencies or manufacturing or supply failures that could result in adverse patient reactions, lot failures, insufficient inventory, product recalls and product liability claims. Additionally, we and our third-party manufacturers, including Genezen, may not be able to scale up some or all our manufacturing processes as necessary and on our desired timelines to meet the demands of our clinical product pipeline, which may result in delays in regulatory approvals, inability to produce sufficient amounts of clinical or commercial product, or otherwise adversely affect our business.

Previous wording

Prior to the Lexington Transaction, we manufactured HEMGENIX® at the Lexington Facility, which is optimized to meet HEMGENIX® product specifications and the commercial manufacturing and supply obligations under our collaboration with CSL Behring. Following the Lexington Transaction, Genezen is responsible for the manufacturing and supply of HEMGENIX® at the Lexington Facility, though we remain contractually obligated to CSL Behring consistent with the terms of the collaboration. While uniQure will have priority and preferential status with Genezen, Genezen may not have sufficient capacity to support our other development programs or those of its other customers, which may negatively impact our businesses and abilities to advance development goals unrelated to HEMGENIX® and our obligations to CSL Behring. The manufacturing of HEMGENIX® pursuant to our obligations under the CSL Behring Agreement is expensive and requires the dedication of significant resources, notwithstanding the Lexington Transaction and our subcontracting to Genezen. In September 2022, CSL Behring notified us of its intent to transfer manufacturing technology in the coming years related to HEMGENIX® to a third-party contract manufacturer to be designated by CSL Behring in the future. Until CSL Behring identifies and designates a new manufacturer capable of supporting the commercial requirements of HEMGENIX®, we will continue to incur significant costs associated with the manufacturing and supply of HEMGENIX®. Moreover, as Genezen will be the entity that is actually engaging in the manufacture of HEMGENIX, should Genezen encounter a manufacturing issues or is unable to provide a sufficient supply of HEMGENIX, we may be unable to fulfil our contractual commitments to CSL Behring and may, thus, face contractual liabilities.

Previous wording

Following such transfer, Genezen may experience challenges in adapting the Lexington Facility to meet the manufacturing and supply needs for products other than HEMGENIX® as a result of excess capacity or the ability to adapt to new processes, among other challenges. Any problems or limitations with respect to our manufacturing processes or facilities, including the existing commercial supply and manufacturing obligations to CSL Behring, could make us a less attractive collaborator for academic research institutions and other parties, which could limit our access to additional attractive development programs or sources of capital, result in delays in our clinical development or marketing schedules and materially harm our business.

Previous wording

We currently rely, and expect to continue to rely, on third parties for the production of our preclinical study and planned clinical trial materials and, therefore, we can control only certain aspects of their activities. Prior to the Lexington Transaction, we manufactured HEMGENIX® in-house at the Lexington Facility. Following the Lexington Transaction, we will rely on Genezen for the production of HEMGENIX® and will have preferential access to the Lexington Facility for the production of materials related to AMT-130 and AMT-191 programs under separately negotiated development and supply arrangements. The facilities used by Genezen and our other contract manufacturers to manufacture certain of our product candidates must be reviewed by the FDA pursuant to inspections that will be conducted after we submit a BLA to the FDA. We do not control the manufacturing process of, and are completely dependent on, Genezen and our other contract manufacturing partners for compliance with the cGMP for the manufacture of our products and product candidates. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or other regulatory bodies, we will not be able to obtain and/or maintain regulatory approval for our products manufactured by third parties. In addition, we have no control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product candidates or if it withdraws any such approval in the future, we may need to find alternative third-party manufacturers, which may not be available and which would significantly impact our ability to develop, obtain regulatory approval for or market our product candidates, if approved.

Moreover, if the Lexington Facility we or our other third-party manufacturers are not able to manufacture a sufficient amount of our product candidates for clinical studies or eventual commercialization, or if a sufficient supply of HEMGENIX® consistent with our manufacturing and supply obligations to CSL Behring, our development programs and commercial prospects will be harmed. If the Lexington Facility or our other third-party manufacturers cannot produce an adequate amount of our drug substance and product in compliance with the applicable regulatory requirements, we may need to contract with a third party to do so, in which case third party manufacturers may not be available to us on favorable terms or at all. The addition of a new manufacturer may also require FDA, EMA, EU, and other regulatory authority approvals, which we may not be able to obtain.

Our development and manufacturing processes and those of our third-party contract manufacturers involve the use of viruses, chemicals, other potentially hazardous materials and produce waste products. Accordingly, we and our third-party manufacturers are subject to national, federal, state, and local laws and regulations in the U.S. and the Netherlands governing the use, manufacture, distribution, storage, handling, treatment, and disposal of these materials. In addition to ensuring the safe handling of these materials, these laws and regulations impose increased safeguards and security measures for many of these agents, including controlling access and screening of entities and personnel who have access to them, and establishing a comprehensive national database of registered entities. In the event of an accident or failure to comply with environmental, occupational health and safety and export control laws and regulations, we or our third-party contract manufacturers could be held liable for damages that result, and any such liability could exceed our assets and resources, and could result in material harm to our business, financial condition, and results of operations.

The manufacture of our AAV gene therapies is complex and requires significant expertise. Even with the relevant experience and expertise, manufacturers of gene therapy products often encounter difficulties in production, particularly in scaling out and validating initial production and ensuring that the product meets required specifications. These problems include difficulties with production costs and yields, quality control, including stability and potency of the product, quality assurance testing, instances of operator error, shortages of qualified personnel, as well as compliance with strictly enforced federal, state, and foreign regulations. In the past and prior to the Lexington Transaction, we have manufactured certain batches of product candidates intended for nonclinical, clinical and process validation purposes that have not met all our pre-specified quality parameters. To meet our expected future production needs and our regulatory filing timelines for gene therapy product candidates, Genezen will need to complete the validation of our manufacturing processes and methods for each program, and we may need to develop and validate new or larger scale manufacturing processes and methods to meet our needs. If Genezen or any other third-party manufacturer we contract with is unable to consistently manufacture our gene therapy product candidates or any approved products in accordance with our pre-specified quality parameters and applicable regulatory standards, it could adversely impact our ability to validate our manufacturing processes and methods, to meet our production needs, to file a BLA or other regulatory submissions, to develop our other proprietary programs, to conserve our cash, or to receive financial payments pursuant to our agreements with third parties.

Regulatory authorities in some jurisdictions, including the U.S. and the European Union, may designate drugs for relatively small patient populations as orphan drugs. While certain of our product candidates, including AMT-130, have received orphan drug designation, there is no guarantee that we will be able to receive such designations in the future. The FDA may grant orphan designation to multiple sponsors for the same compound or active molecule and for the same indication. If another sponsor receives FDA approval for such product before we do, we would be prevented from launching our product in the U.S. for the orphan indication for a period of at least seven years unless we can demonstrate clinical superiority.

We rely, in part, upon a combination of forms of intellectual property, including in-licensed and owned patents to protect our intellectual property. Our success depends in large part on our ability to obtain and maintain this protection in the U.S., the European Union, and other countries, in part by filing patent applications related to our novel technologies and product candidates. Our patents may not provide us with any meaningful commercial protection, prevent competitors from competing with us or otherwise provide us with any competitive advantage. The patents we own currently are and may become subject to future patent opposition or similar proceedings. Additionally, the patent prosecution process is expensive, time-consuming, and uncertain, and in certain instances we have chosen, and in the future we may choose, not to file and prosecute all necessary or desirable patent applications. For example, our defense of certain patent cases in each of Canada, the United Kingdom, the Netherlands and the U.S. pertaining to licensed rights of etranacogene dezaparvovec was assumed by CSL Behring on October 11, 2023. These oppositions and future patent oppositions may result in loss of scope of some claims or the entire patent and, with respect to our rights under the CSL Agreement, could affect CSL’s successful commercialization of HEMGENIX® and, in turn, could negatively impact our financial position. Additionally, our competitors may be able to circumvent our owned or licensed patents by developing similar or alternative technologies or products in a non-infringing manner.

We had a net loss of $121.9 million in the six months ended June 30, 2024, and a net loss of $308.5 million in the year ended December 31, 2023. We incurred a gain of $329.6 million in year ended December 31, 2021; however, such gain was primarily attributable to one-time license revenue from CSL Behring. We have incurred significant losses in the years prior to 2021. As of June 30, 2024, we had an accumulated deficit of $1,012.3 million. In the past, we have financed our operations primarily through the sale of equity securities and convertible debt, venture loans, upfront payments from our collaboration partners and, to a lesser extent, subsidies and grants from governmental agencies and fees for services. We expect to finance our operations in 2024 and through the end of 2027 primarily from our existing cash, cash equivalents, and cash resources. We have devoted substantially all our financial resources and efforts to research and development, including preclinical studies and clinical trials. We expect to continue to incur significant expenses and losses over the next several years, and our net losses may fluctuate significantly from quarter to quarter and year to year.

We had a net loss of $166.3 million in the nine months ended September 30, 2024, and a net loss of $308.5 million in the year ended December 31, 2023. We incurred a gain of $329.6 million in year ended December 31, 2021; however, such gain was primarily attributable to one-time license revenue from CSL Behring. We incurred significant losses in the years prior to 2021. As of September 30, 2024, we had an accumulated deficit of $1,056.7 million. In the past, we have financed our operations primarily through the sale of equity securities and convertible debt, venture loans, upfront payments from our collaboration partners and, to a lesser extent, subsidies and grants from governmental agencies and fees for services. We expect to finance our operations in 2024 and through the end of 2027 primarily from our existing cash, cash equivalents, and cash resources. We have devoted substantially all our financial resources and efforts to research and development, including preclinical studies and clinical trials. We expect to continue to incur significant expenses and losses for the foreseeable future, and our net losses may fluctuate significantly from quarter to quarter and year to year. We anticipate that we will continue to incur net losses for the foreseeable future as we:

As of June 30, 2024, we had $100.0 million of outstanding principal of borrowings under the 2024 Amended Facility. In July 2024, in connection with the closing of the Lexington Transaction, we repaid $50.0 million of the principal outstanding. We are required to repay the remaining outstanding principal balance of $50.0 million upon the maturity date of the 2024 Amended Facility in January 2027. We might not be able to finance our operations from our existing cash, cash equivalents, and cash resources consistent with our expectations if we are not able to refinance the 2024 Amended Facility prior to the January 2027 maturity date. We could in the future incur additional debt obligations beyond our borrowings from Hercules. Our existing loan obligations, together with other similar obligations that we may incur in the future, could have significant adverse consequences, including:

Previous wording

Our 2024 Amended Facility bears a variable interest rate with a fixed floor. The U.S. Federal Reserve has raised, and may in the future further raise, interest rates to combat the effects of recent high inflation. An increase in interest rates by the Federal Reserve has and could in the future cause the prime rate to increase, which has and could in the future increase our debt service obligations. Significant increases in such obligations could have a negative impact on our financial position or operating results, including cash available for servicing our indebtedness, or result in increased borrowing costs in the future

In October 2023, we commenced a restructuring of our business to reprioritize our portfolio of development candidates, conserve financial resources and better align our workforce with current business needs. In June 2024, we announced the sale of the Lexington Facility and related manufacturing assets in conjunction with our broader efforts to reduce operating expenses and cash burn. In addition, in August 2024, we announced the outcome of our strategic review intended to conserve capital, streamline operations and ensure sufficient cash resources to advance multiple clinical-stage programs through potentially meaningful milestones. This restructuring, inclusive of the sale of our Lexington facility and associated employee transitions to Genezen, involves the elimination of approximately 65% of our global workforce, or approximately 300 roles across the Company, and is subject to the review by our Amsterdam-based works council, which is expected to be completed in the third quarter of 2024. We anticipate that the restructuring will be substantially complete in the fourth quarter of 2024. We may encounter challenges in the execution of these and future restructuring efforts, and these challenges could impact our financial results.

Previous wording

Although we believe that these actions will reduce operating costs, we cannot guarantee that these restructuring efforts will achieve or sustain the targeted benefits, or that the benefits, even if achieved, will be adequate to meet our long-term expectations and the needs of our business. As a result of these restructuring efforts, we will likely incur additional costs in the near term, including cash expenditures for employee transitions, notice periods and severance payments, costs associated with employee benefit programs and related restructuring facilitation and transaction costs. Additional risks associated with the continuing impact of these restructuring efforts include employee attrition beyond our intended reduction in force and adverse effects on employee morale (which may also be further exacerbated by actual or perceived declining value of equity awards), diversion of management attention, adverse effects to our reputation as an employer (which could make it more difficult for us to hire and retain new employees in the future), potential understaffing and potential failure or delays to meet development targets due to the loss of qualified employees or other operational challenges. If we do not realize the expected benefits of our restructuring efforts on a timely basis or at all, our business, results of operations and financial condition could be adversely affected.

Following periods of such volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Because of the potential volatility of our stock price, we may become the target of securities litigation in the future. In addition, notwithstanding protective provisions in our articles of association and available to us under Dutch corporate law, market volatility may lead to increased shareholder activism if we experience a market valuation that activist investors believe is not reflective of the intrinsic value of our ordinary shares. Activist campaigns that contest or conflict with our strategic direction or seek changes in the composition of our board of directors could have an adverse effect on our operating results and financial condition. Securities litigation or shareholder activism could result in substantial costs and divert management’s attention and resources from our business.

Our directors, executive officers and major shareholders holding more than 5% of our outstanding ordinary shares, in the aggregate, beneficially own approximately 26.9% of our issued shares (including such shares to be issued in relation to exercisable options to purchase ordinary shares) as of June 30, 2024. As a result, if these shareholders were to choose to act together, they may be able, as a practical matter, to control many matters submitted to our shareholders for approval, as well as our management and affairs. For example, these persons, if they choose to act together, could control the election of the board of directors and the approval of any merger, consolidation, or sale of all or substantially all our assets. These shareholders may have interests that differ from those of other of our shareholders and conflicts of interest may arise.

The Lexington Transaction may not ultimately reduce our operating expenses to a magnitude consistent with our expectations. In addition, we may be exposed to additional costs and risks related to or as a result of the Lexington Transaction, including, without limitation (i) additional expenses associated with outsourcing certain manufacturing and development services, as well as our contractual obligations and minimum financial commitments to Genezen under the CSA and the DMSA, (ii) supply-related risks related Genezen’s ability and capacity to satisfy our continued obligations to CSL Behring and the supply of our other product candidates, including AMT-130, (iii) contractual default under our agreements with Genezen or with CSL Behring, and (iv) other third-party risks relative to our partnership with Genezen (see “—Risks Related to our Dependence on Third Parties”). The occurrence of any of the foregoing or any other risks as a result of or related to the Lexington Transaction could considerably harm our business and impact our financial condition and results of operations.

There are numerous factors that could impede or otherwise negatively impact our further development of AMT-130, including, but not limited to, patient safety issues, our failure to demonstrate sufficient clinical efficacy or durability of response data to warrant further development, delays in our ability to enroll patients or challenges with potential development partners, clinical trials or regulatory authorities. Any one or combination of these factors could force us to halt or discontinue the ongoing clinical trials of AMT-130. Certain of these risk factors are heightened in the context of drug development for rare diseases like Huntington’s disease and novel investigational products like gene therapies in which non-traditional study designs are utilized to demonstrate efficacy and safety, including open-label studies, single arm studies, studies utilizing active comparators or natural history data, biomarkers or other forms
