Item 1A. Risk Factors

Current report

We do not currently have sufficient working capital to fund our planned operations for the next twelve months and substantial doubt exists as to our ability to continue as a going concern.*

Current report

For the nine months ended September 30, 2026, we had incurred a net loss of $52.5 million and used $44.6 million of cash in operations. As of September 30, 2026, we had an accumulated deficit of $341.7 million and cash and cash equivalents of $87.7 million. We expect to continue to generate operating losses and have significant cash outflows from operating activities for at least the next few years. Until we can generate sufficient revenue, if ever, to fund our operations, we will need to finance future cash needs through sales of one or more priority review vouchers, if received, public or private equity offerings, license agreements, debt financings or restructurings, collaborations, strategic alliances and marketing or distribution arrangements, and there can be no assurance that such arrangements will be available to us on a timely basis, or, if available, will be available on terms acceptable to us. Without alternative financing or proceeds from other strategic alternatives, we believe, based on our current operating plan, that our cash and cash equivalents as of September 30, 2026 will be insufficient to fund our operations and debt obligations for at least twelve months following the issuance date of our unaudited financial statements included elsewhere in this Quarterly Report. These conditions raise substantial doubt about our ability to continue as a going concern.

Current report

The perception of our ability to continue as a going concern may make it more difficult for us to obtain financing for the continuation of our operations and could result in the loss of confidence by investors and employees. If we are not able to obtain the necessary additional financing on a timely or commercially reasonable basis, we will be forced to delay or scale down some or all of our development activities (or perhaps even cease the operation of our business). If we are unable to continue as a going concern, our stockholders may lose some or all of their investment in the Company.

Current report

In the second quarter of 2026, we completed two pre-BLA meetings with the FDA. In these meetings, the FDA generally agreed with our proposed approach to the overall content and format of the BLA, including the structure of the integrated summaries of efficacy and safety, and indicated that our drug substance and drug product analytical comparability strategies following the transfer of TA-ERT manufacturing to a global biologics contract manufacturer appeared reasonable to support the BLA. The FDA also requested that we initiate our TrAnsform confirmatory study during the FDA’s review of the BLA. We completed the first PPQ batch in July 2026, and data from this batch will be included in the BLA; we expect to complete the second PPQ batch in December 2026 and to provide data from that batch prior to the mid-cycle of the FDA’s review. However, feedback from the FDA in pre-BLA meetings is not binding, and during its review of our BLA the FDA may disagree with our approach, including with respect to analytical comparability, the adequacy of our PPQ data, the use of our integrated clinical and natural history data, or the design of our confirmatory study. If we are unable to complete the second PPQ batch on our anticipated timeline, or if its results are not satisfactory, the FDA’s review of our BLA could be delayed or the FDA could issue a Complete Response Letter.

Current report

Even if we obtain accelerated approval, under the Food and Drug Omnibus Reform Act of 2022 (“FDORA”), the FDA may use expedited procedures to withdraw approval if, among other things, our confirmatory trial fails to verify the predicted clinical benefit of TA-ERT, we fail to conduct the confirmatory trial with due diligence, or other evidence demonstrates that TA-ERT is not shown to be safe or effective under its conditions of use. Enrolling and completing a randomized, controlled confirmatory trial in a small pediatric population with a rapidly progressing, fatal disease may be particularly challenging, including because caregivers may be unwilling to enroll children in a trial in which they may be randomized to standard of care, particularly once TA-ERT is commercially available. In addition, although in March 2026 the FDA granted accelerated approval to another therapy for a neuronopathic mucopolysaccharidosis based on reductions in CSF heparan sulfate, the FDA’s decisions with respect to other product candidates are not necessarily predictive of the outcome of its review of our BLA, and the FDA’s approach to surrogate endpoints in rare neurodegenerative diseases continues to evolve.

Current report

We may not receive a rare pediatric disease priority review voucher for TA-ERT, and, even if we do, we may not be able to sell it on favorable terms, on a timely basis or at all.*

Current report

TA-ERT has received Rare Pediatric Disease Designation from the FDA. In February 2026, the Mikaela Naylon Give Kids a Chance Act, enacted as part of the Consolidated Appropriations Act, 2026, reauthorized the FDA’s rare pediatric disease priority review voucher program for drugs and biologics designated as such through September 30, 2029, subject to the conditions of the statute. A voucher is awarded only upon approval of a qualifying application that meets the statutory requirements, and the FDA may determine that our BLA does not qualify. Our current funding plans contemplate the potential sale of one or more priority review vouchers. If we do not receive a voucher, or if we are unable to sell a voucher we receive at an attractive price or on a timely basis, including as a result of changes in the supply of or demand for vouchers, our liquidity and ability to fund our operations, including the commercial launch of TA-ERT and repayment of the Avenue Loans, could be materially adversely affected. In addition, the program may be modified or allowed to lapse in the future.

Current report

In addition, no amounts were drawn under Tranche 2 prior to the expiration of its original availability period on September 30, 2026. In November 2026, we entered into an amendment to the Avenue Loan Agreement (the “Avenue Amendment”) pursuant to which, among other things, Tranche 2 was increased to up to $15.0 million and made available between January 1, 2027 and March 31, 2027, and Tranche 3 was made available between July 1, 2027 and December 31, 2027 at the discretion of the Lender. The Avenue Amendment also extended the interest-only period under the Avenue Loans through March 31, 2027. Our ability to draw Tranche 2, and to further extend the interest-only period through October 31, 2027 and thereafter through October 31, 2028, is subject to the satisfaction of certain conditions, some of which are outside of our control, and Tranche 2 may expire before the end of its availability period in certain circumstances. If we do not satisfy these conditions, we will not be able to borrow under Tranche 2, and we will be required to begin making monthly principal payments in April 2027. The Lender may decline to fund Tranche 3 or the Discretionary Tranche 4 in its sole discretion. In addition, the Avenue Loan Agreement restricts our ability to transfer assets, including intellectual property, and to make investments in subsidiaries, and the Separation of Adrenyx required Avenue’s consent, including for the release of Avenue’s lien on the assets contributed to Adrenyx.

Risks Related to the Separation of Adrenyx and Planned Distribution

Current report

The separation of our CRHX-101 (formerly known as SPR202) program into Adrenyx and the planned distribution of Adrenyx shares to our stockholders may not be completed on the anticipated timeline or at all, may not achieve the intended benefits, and could disrupt our business and divert management attention.*

Current report

In November 2026, our board of directors approved a plan to separate our CRHX-101 program (the “Separation”) into Adrenyx Biosciences, Inc., our wholly-owned subsidiary. We currently intend to distribute all of the outstanding shares of Adrenyx common stock to our stockholders on a pro rata basis (the “Distribution”), although our board of directors has not yet approved the Distribution or set a record date for the Distribution. The Distribution is subject to a number of conditions, including approval by our board of directors, the effectiveness of a registration statement filed by Adrenyx with the SEC, and the approval for listing of Adrenyx common stock on Nasdaq. Our board of directors may abandon or modify the planned Distribution at any time. We may not satisfy these conditions, and the Distribution may be delayed or may not occur at all.

Current report

We have incurred, and expect to continue to incur, significant costs in connection with the Separation and the planned Distribution, including legal, accounting, tax and advisory fees, many of which will be incurred whether or not the Distribution is completed. The Distribution requires significant time and attention from our management and board of directors, which could divert attention from our planned BLA submission for TA-ERT, the FDA’s review of our BLA and our preparations for the potential commercial launch of TA-ERT. Certain of our officers and directors are expected to serve as officers or directors of, or consultants to, Adrenyx, and may have actual or apparent conflicts of interest with respect to matters involving both companies, including the negotiation and administration of the agreements governing the Separation and the Distribution. Following the Distribution, we will provide certain transition services to Adrenyx under the transition services agreement we entered into in November 2026, which could further burden our limited personnel and resources.

Current report

The Distribution is intended to be a taxable transaction for U.S. federal income tax purposes. We may recognize taxable gain, and our stockholders may be treated as receiving a taxable distribution, in each case based on the fair market value of the Adrenyx shares at the time of the Distribution, which cannot be predicted, and our ability to offset any such gain with our NOLs and other tax attributes may be limited. Following the Distribution, we will no longer own the CRHX-101 program, and the trading price of our common stock may decline to reflect the Distribution. We cannot predict the trading prices of our common stock or Adrenyx common stock following the Distribution, and the combined trading prices may be less than the trading price of our common stock prior to the Distribution. Under the Separation Agreement, liabilities relating to the CRHX-101 program are allocated between the Company and

Current report

Adrenyx, and we and Adrenyx have agreed to indemnify one another for certain liabilities arising from the Separation and planned Distribution.

Current report

In November 2026 in connection with the Separation, Adrenyx issued secured convertible promissory notes to a leading institutional biotechnology investor, which are secured by substantially all assets of Adrenyx. Prior to the Distribution, Adrenyx’s results, including its financing activities, are consolidated in our financial statements and may increase our reported net loss and liabilities, and any conversion of such notes or other Adrenyx financings will dilute our stockholders’ indirect interest in Adrenyx.

Current report

Under the BioMarin License Agreement, we are obligated to pay BioMarin up to $25.5 million upon the achievement of certain milestones for the first MPS IIIB product and up to an aggregate of $100.0 million per licensed product upon the achievement of certain sales milestones, as well as tiered royalties ranging from the high-single digits to the low-double digits on annual net sales of licensed MPS IIIB products, subject to certain customary reductions and floors. BioMarin may terminate the BioMarin License Agreement if we challenge the licensed patents, cease all material research and development activity for licensed products for a specified period of time, materially breach the agreement and fail to cure such breach within a specified period, or become subject to bankruptcy or insolvency. Termination of the BioMarin License Agreement would result in the loss of our rights to TA-ERT and would materially harm our business.

Current report

Moreover, any name we have proposed to use with our product candidates in the United States must be approved by the FDA, regardless of whether we have registered it, or applied to register it, as a trademark. The FDA typically conducts a review of proposed product names, including an evaluation of potential for confusion with other product names. If the FDA (or an equivalent administrative body in a foreign jurisdiction) objects to any of our proposed proprietary product names, it may be required to expend significant additional resources in an effort to identify a suitable substitute name that would qualify under applicable trademark laws, not infringe the existing rights of third parties, and be acceptable to the FDA. Similar requirements exist in Europe. Furthermore, in

Separation and Distribution Agreement

Current report

On November 6, 2026, our board of directors approved a plan to separate and contribute our CRHX-101 program into Adrenyx (the “Separation”). We currently intend to distribute all of the outstanding shares of Adrenyx common stock to our stockholders on a pro rata basis (the “Distribution”), in a transaction that is intended to result in two independent public companies, although our board of directors has not yet approved the Distribution or set a record date for the Distribution.

Current report

Also on November 6, 2026, we and Adrenyx entered into a series of agreements, including a separation and distribution agreement (the “Separation Agreement”) and a transition services agreement (the “Transition Services Agreement”). Pursuant to the Separation Agreement, among other things, we contributed to Adrenyx certain assets and liabilities relating to the CRHX-101 program as part of the Separation, including assignment of the HBM License Agreement. The Separation Agreement sets forth the conditions to, and the procedures for effecting, the Distribution, subject to approval by our board of directors.

Current report

We will provide certain services to Adrenyx for a period of up to 12 months following the Distribution, subject to extension, compensated by Adrenyx as provided in the Transition Services Agreement.

Current report

The Distribution is expected to be completed in the first half of 2027, with a private placement of Adrenyx equity securities expected to be completed in connection with the Distribution, subject to the satisfaction or waiver of certain conditions, including the effectiveness of a registration statement filed by Adrenyx with the SEC, approval of the listing of Adrenyx common stock on Nasdaq, and our board of directors having declared the Distribution. Approval by our stockholders is not required as a condition to the consummation of the Distribution. The Distribution is intended to be a taxable transaction for U.S. federal income tax purposes. There can be no assurance that the Distribution will be completed on the anticipated timeline, on the anticipated terms or at all.

Private Placement Financing

Previous report

On August 7, 2026, we entered into a Stock Purchase Agreement (the “Purchase Agreement”) with the National MPS Society and the Cure Sanfilippo Foundation (the “Purchasers”), pursuant to which we agreed to sell and issue to the Purchasers 121,203 shares of the Company’s common stock in a private placement transaction (the “Private Placement”). The purchase price per share was $45.38. The closing of the Private Placement occurred on August 10, 2026 (the “Closing”). The total gross proceeds we received at the Closing was $5.5 million. The proceeds will be used to partially fund the Company’s planned open-label, single-arm early access program to provide TA-ERT for the treatment of MPS IIIB in children.

As of June 30, 2026, we had cash and cash equivalents of $96.3 million. In October 2020, we consummated our initial public offering and issued 92,000 shares of common stock for net proceeds of $93.4 million. In February 2023, we completed a private placement for net proceeds of $50.9 million. In April 2023, we received a $15.0 million upfront payment under a collaboration and license agreement with Kaken Pharmaceutical Co. Ltd. In October 2025, we completed a private placement for total net proceeds of $46.6 million. On January 7, 2026, we entered into the Avenue Loan Agreement, which makes available to the company term loans in an aggregate principal amount of up to $50.0 million, subject to the company’s achievement of certain regulatory milestones, which we may not achieve. On April 22, 2026, we closed our previously announced underwritten public offering of 1,150,000 shares of our common stock and pre-funded warrants to purchase up to 50,000 shares of our common stock, and we granted the underwriters a 30-day option to purchase up to 180,000 additional shares of common stock, which was exercised in full. The net proceeds to us from the offering were $64.4 million. Additionally, in August 2026 we completed a private placement for gross proceeds of $5.5 million.

We may seek additional capital through a combination of equity offerings, debt financings, strategic partnerships and alliances, and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a stockholder. The incurrence of indebtedness would result in increased fixed payment obligations and could involve certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire or license intellectual property rights, and other operating restrictions that could adversely impact our ability to conduct our business. For example, on January 7, 2026, we entered into the Avenue Loan Agreement, which contains covenants restricting, among other things, our ability to incur additional indebtedness, liens, guaranties, mergers and consolidations, substantial asset sales, investments and loans, certain corporate changes, transactions with affiliates and fundamental changes. If we raise additional funds through strategic partnerships and alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or current or future product candidates, or grant licenses on terms unfavorable to us.

We are a late-stage biopharmaceutical company incorporated in 2016, and our operations to date have focused primarily on raising capital, establishing and protecting our intellectual property portfolio, organizing and staffing our company, business planning, and conducting preclinical and clinical development of, and manufacturing development for, our product candidates. Additionally, as an organization, we have not yet demonstrated an ability to successfully complete clinical development, obtain regulatory approvals, manufacture a commercial-scale product, or conduct sales and marketing activities necessary for successful commercialization. As we build our capabilities and expand our organization, we have not yet demonstrated an ability to overcome many of the risks and uncertainties frequently encountered by companies in new and rapidly evolving fields, particularly in the biopharmaceutical area. Consequently, any predictions about our future performance may not be as accurate as they would be if we had a history of successfully developing and commercializing biopharmaceutical products.

Investment in biopharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and significant risk that any potential product candidate will fail to demonstrate adequate effectiveness in the targeted indication or an acceptable safety profile, gain regulatory approval and become commercially viable. We have no products approved for commercial sale and have not generated any product revenue to date, and we continue to incur significant research and development and other expenses related to our ongoing operations. As a result, we are not profitable and have incurred significant net losses since our inception. If our product candidates are not successfully developed and approved, we may never generate any revenue. For the six months ended June 30, 2026 and 2025, we reported net losses of $28.5 million and $16.1 million, respectively. As of June 30, 2026, we had an accumulated deficit of $317.7 million.

We intend to seek FDA approval of TA-ERT for MPS IIIB through the accelerated approval pathway.

Previous wording

We intend to submit a biologics license application (“BLA”) seeking accelerated approval of TA-ERT for MPS IIIB based on existing clinical data, however there can be no assurance that such submission or application will be accepted for filing by the FDA or that approval will be granted on a timely basis, or at all. For example, in March 2024, in a type C meeting with the FDA, the FDA confirmed that CSF HS-NRE is deemed to be a biomarker reasonably likely to predict clinical benefit and could serve as a basis for accelerated approval. The FDA also confirmed that the completed clinical and nonclinical studies of TA-ERT were sufficient for a BLA submission and provided guidance around key design elements of a confirmatory trial (placebo-controlled 5-year study in 14 patients), which must be initiated prior to potential accelerated approval of TA-ERT.

We intend to submit a biologics license application (“BLA”) seeking accelerated approval of TA-ERT for MPS IIIB based on existing clinical data; however, there can be no assurance that such submission or application will be accepted for filing by the FDA or that approval will be granted on a timely basis, or at all. In March 2024, in a Type C meeting between the FDA and Allievex, the prior sponsor of TA-ERT, the FDA indicated that it considered cerebrospinal fluid heparan sulfate non-reducing end (“CSF HS-NRE”) to be a biomarker reasonably likely to predict clinical benefit and could serve as a basis for accelerated approval. The FDA also indicated that the completed clinical and nonclinical studies of TA-ERT appeared sufficient to support a BLA submission and provided guidance around key design elements of a confirmatory trial (placebo-controlled 5-year study in 14 patients), which, under the FDA’s more recent guidance to us, we must initiate during the FDA’s review of our BLA as a condition of potential accelerated approval. Our current design for this study, which we refer to as TrAnsform, is a randomized, single-blind, parallel-group, controlled, multicenter study evaluating the safety, tolerability and efficacy of intracerebroventricular (“ICV”)-administered TA-ERT compared to standard of care in children 1 to 5 years of age with severe (non-attenuated) MPS IIIB, with cognition as the primary objective.

We also held two Type B meetings with the FDA ahead of our anticipated BLA submission for TA-ERT; the first in December 2025 to discuss our clinical data and regulatory strategy, and the second in January 2026 to discuss CMC requirements. During the December 2025 meeting, the FDA confirmed that the integrated study data from interventional clinical studies of TA-ERT and the available natural history data could potentially serve as an adequate and well-controlled study for purposes of the FDA’s review of the effects of TA-ERT on CSF HS-NRE, which could serve as a surrogate endpoint to support an accelerated approval. Following the January 2026 CMC meeting, the FDA considered the company’s plan to address DP PPQ batch requirements for the BLA submission, and in the official meeting minutes, the FDA shared its requirement for one DP PPQ batch at the time of BLA submission and data from a second DP PPQ batch prior to midcycle of BLA review.

Based, in part, on these discussions, we intend to submit the BLA for TA-ERT for the treatment of MPS IIIB in the fourth quarter of 2026, and if successful and FDA approval is received, potentially commercially launch in mid-2027. However, even if we submit the BLA as planned, we may be unsuccessful in providing sufficient evidence of CSF HS-NRE to predict clinical benefit in support of an accelerated approval, and after reviewing our BLA submission, the FDA may ultimately issue a Complete Response Letter. For example, the FDA has in the past rejected accelerated approval following submission of a BLA under accelerated approval pathway by another company focusing on the treatment of an ultra-rare neurodegenerative disease, in part due to uncertainty regarding the appropriateness of the proposed surrogate endpoint, and the FDA may reject similar BLA applications in the future. If our BLA submission is viewed as having similarities to another BLA submission that was previously rejected by the FDA, this could impact the likelihood of success of our BLA application or could influence investor perception of our likelihood of success, which could cause the price of our common stock to decline, and could harm our business, financial condition, results of operations and prospects. If the FDA rejects CSF HS-NRE as a surrogate endpoint, we may be required to conduct longer-term follow up, to enroll additional patients in our current study, or to perform a new clinical study, all of which could be challenging with an ultra-rare and fatal genetic disease like MPS IIIB and could make us experience significant delays in, or could prevent us from, obtaining accelerated regulatory approval. Failure to obtain accelerated approval would result in a longer time period to commercialization, if any, and would increase the cost of development and harm our competitive position in the marketplace.

Previous wording

Before obtaining regulatory approvals for the commercial sale of a product candidate, we must demonstrate through lengthy, complex, and expensive preclinical testing and clinical trials that a product candidate is both safe and effective for use in each target indication. Clinical trials often fail to demonstrate safety and efficacy of the product candidate studied for the target indication. Most product candidates that commence clinical trials are never approved by regulatory authorities for commercialization. We are seeking to develop treatments for MPS IIIB and congenital adrenal hyperplasia (“CAH”). We intend to seek accelerated approval of TA-ERT for MPS IIIB based on existing clinical data. As a condition of seeking such approval of a BLA from the FDA, we will initiate a confirmatory Phase 3 trial, which must be initiated prior to potential accelerated approval of TA-ERT. We intend to submit the BLA for TA-ERT for the treatment of MPS IIIB in the fourth quarter of 2026, and if successful and FDA approval is received, potentially commercially launch in mid-2027. Additionally, any safety concerns observed in any one of our clinical trials in our targeted indications could limit the prospects for regulatory approval of TA-ERT and our other current product candidates in other indications.

Preclinical and clinical drug development involves a lengthy and expensive process with uncertain outcomes, and results of earlier studies and trials may not be predictive of future trial results. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of TA-ERT and our other current and future product candidates.*

Previous wording

Before obtaining marketing approval from regulatory authorities for the sale of any of our product candidates, we or our collaborators must conduct extensive trials to demonstrate the safety and efficacy of the product candidates in humans. Preclinical and clinical testing is expensive and difficult to design and implement, can take many years to complete, and its outcome is inherently uncertain. A failure of one or more preclinical or clinical trials can occur at any stage of testing. The results of preclinical studies and early clinical trials of TA-ERT and preclinical studies of SPR202 may not be predictive of the results of later-stage clinical trials, and interim results of a trial do not necessarily predict final results. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. For example, we plan to use doses in our clinical trials for TA-ERT that may not be safe or efficacious doses. As such, our hypotheses of efficacy may not show the desired clinical results. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or safety profiles, notwithstanding promising results in earlier trials. Moreover, preclinical and clinical data is often susceptible to varying interpretations and analyses. For example, the Tildacerfont as Antidepressant Medication and Relief in Depression (“TAMARIND”) Phase 2 study of tildacerfont in major depressive disorder (“MDD”) was discontinued in the first quarter of 2026 following a serious adverse event in which a patient experienced a significant elevation of liver enzymes. The prior sponsor of TA-ERT, Allievex Corporation (“Allievex”), discontinued clinical development due to financial constraints.

In the United States, we are not permitted to market TA-ERT or any other current or future product candidates until we receive regulatory approval from the FDA. The process of obtaining regulatory approval is expensive, often takes many years following the commencement of clinical trials and can vary substantially based upon the type, complexity, and novelty of the product candidates involved, as well as the target indications and patient population. Approval policies or regulations may change, and the FDA has substantial discretion in the drug approval process, including the ability to delay, limit, or deny approval of a product candidate for many reasons. Despite the time and expense invested in clinical development of product candidates, regulatory approval is never guaranteed. Neither we nor any future collaborator is permitted to market TA-ERT or any other current or future product candidates in the United States until we receive approval of a new drug application (“NDA”) or BLA from the FDA. Similar requirements and risks are applicable in foreign markets. We have not previously submitted an NDA or BLA to the FDA, or similar drug approval filings to comparable foreign authorities.

Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the United States, including additional preclinical studies or clinical trials as clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, including a number of countries in the EU, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our product candidates is also subject to approval.

A severe or prolonged global economic downturn could result in a variety of risks to our business. For example, inflation rates, particularly in the United States, have increased to levels not previously seen in years, and increased inflation may result in increases in our operating costs (including our labor costs), reduced liquidity and limits on our ability to access credit or otherwise raise capital on acceptable terms, if at all. In addition, the U.S. Federal Reserve and equivalent foreign entities have raised, and may again raise, interest rates in response to concerns about inflation, which, coupled with reduced government spending and volatility in financial markets may have the effect of further increasing economic uncertainty and heightening these risks. Risks of a prolonged global economic downturn are particularly true in Europe, which is undergoing a continued severe economic crisis. A weak or declining economy could also strain our suppliers and manufacturers, possibly resulting in supply disruption. Any of the foregoing could harm our business and we cannot anticipate all of the ways in which the current economic climate and financial market conditions could adversely impact our business.

We operate in a global economy, which includes utilizing third-party suppliers in several countries outside the United States. There is inherent risk, based on the complex relationships among the United States and the other countries in which we conduct our business, that political, diplomatic, and national security factors can lead to global trade restrictions and changes in trade policies and export regulations that may adversely affect our business and operations. The current international trade and regulatory environment is subject to significant ongoing uncertainty. The U.S. government has announced imposition of substantial tariffs affecting a wide range of products and jurisdictions and has indicated an intention to continue developing new trade policies, including with respect to the pharmaceutical industry. In response, certain foreign governments have announced or implemented retaliatory tariffs and other protectionist measures. These developments, including legal challenges to such tariffs, have created a dynamic and unpredictable trade landscape, which may adversely impact our business, results of operations, financial condition and prospects. The Bureau of Industry and Security, U.S. Department of Commerce, has initiated an investigation to determine whether pharmaceutical ingredients, including finished drug product, manufactured outside the United States, pose a national security risk and should be subject to additional tariffs. Based on this investigation, on April 2, 2026, the President issued a proclamation imposing up to a 100% tariff on certain patented pharmaceuticals and associated pharmaceutical ingredients. These tariffs will become effective September 29, 2026, unless they are “expressly reduced, modified, or terminated.”

In February 2026, the U.S. Supreme Court held that the International Emergency Economic Powers Act does not authorize the imposition of tariffs, and the administration has since imposed or announced tariffs under other statutory authorities. In April 2025, the Bureau of Industry and Security of the U.S. Department of Commerce initiated an investigation under Section 232 of the Trade Expansion Act of 1962 to determine whether imports of pharmaceuticals and pharmaceutical ingredients, including finished drug products, pose a national security risk. Based on this investigation, on April 2, 2026, the President issued a proclamation imposing a tariff of up to 100% on certain imported patented pharmaceuticals and associated pharmaceutical ingredients, which became effective for most importers, including us, on September 29, 2026. The proclamation provides for reduced rates or exemptions in certain circumstances, including reduced rates for products from certain jurisdictions that have current or forthcoming trade and security framework agreements with the United States, such as the EU, Japan and South Korea, and a 0% rate for certain orphan drugs that satisfy specified conditions. There can be no assurance that TA-ERT or the materials we import will qualify for any reduced rate or exemption, or that the scope, rates or exemptions under the proclamation will not change.

As is the case with biopharmaceuticals generally, it is likely that there may be side effects and adverse events associated with the use of TA-ERT and our other current and future product candidates. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics. Undesirable side effects caused by TA-ERT and our other current and future product candidates could cause us or regulatory authorities to interrupt, delay, terminate or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign authorities. For example, in the first quarter of 2026, the TAMARIND Phase 2 clinical trial of tildacerfont in MDD was discontinued following a serious adverse event in which a patient experienced a significant elevation of liver enzymes. In addition, although in clinical trials TA-ERT has demonstrated an adequate safety profile in a serious and fatal disease for which no treatment is currently available, the most frequent treatment-emergent adverse events (TEAE) by preferred term (reported in ≥40% of participants) was vomiting (22 [100%]), followed by pyrexia (20 [90.9%]), upper respiratory tract infection (17 [77.3%]), pleocytosis (11 [50.0%]), COVID-19 infection (10 [45.5%]), and diarrhea (9 [40.9%]). Four (18%) patients discontinued treatment, although three (14%) discontinuations were due to hydrocephalus, a known complication of MPS IIIB. Adverse events related to the intracerebroventricular (“ICV”) device were consistent with other therapies administered by the ICV route.

In addition, if the FDA or a comparable foreign regulatory authority approves a product candidate, the manufacturing, quality control, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion, import, export, and recordkeeping for the approved product will be subject to extensive and ongoing regulatory requirements. The FDA and comparable foreign regulatory authorities also require submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMP requirements and GCP for any clinical trials that we conduct post-approval. Later discovery of previously unknown problems with a product candidate, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:

In addition, if the FDA or a comparable foreign regulatory authority approves a product candidate, the manufacturing, quality control, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion, import, export, and recordkeeping for the approved product will be subject to extensive and ongoing regulatory requirements. The FDA and comparable foreign regulatory authorities also require submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMP requirements and GCP for any clinical trials that we conduct post-approval. Later discovery of previously unknown problems with a product candidate, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in the FDA or comparable foreign regulatory authorities taking actions to, among other things:

Advertising and promotion of any product candidate that obtains approval in the United States will be heavily scrutinized by the FDA, the U.S. Federal Trade Commission, the Department of Justice (“DOJ”), the Office of Inspector General of the U.S. Department of Health and Human Services (“HHS”), state attorneys general, members of the U.S. Congress, and the public. Additionally, advertising and promotion of any product candidate that obtains approval outside of the United States will be heavily scrutinized by comparable foreign entities and stakeholders. Violations, including actual or alleged promotion of our products for unapproved or off-label uses, are subject to enforcement letters, inquiries, and investigations, and civil and criminal sanctions by the FDA, DOJ, or comparable foreign authorities. Any actual or alleged failure to comply with labeling and promotion requirements may result in fines, warning letters, mandates to corrective information to healthcare practitioners, injunctions, or civil or criminal penalties.

The ability of the FDA or comparable foreign regulatory authorities to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes. Average review times at the authorities have fluctuated in recent years as a result. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable.

In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable. In addition, in 2025, HHS implemented significant workforce reductions, including at the FDA, and the FDA has experienced substantial turnover in senior leadership and review staff, which could affect the FDA’s ability to meet review goal dates, conduct pre-license inspections and respond to sponsor communications in a timely manner.

Previous wording

Disruptions at the FDA and other agencies or comparable foreign regulatory authorities may also slow the time necessary for new drugs to be reviewed and/or approved, which would adversely affect our business. For example, over the last several years, including during the government shutdown that began on October 1, 2025, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.

Current federal appropriations for many agencies, including the FDA, are provided under a continuing resolution that expires on December 11, 2026, and a lapse in appropriations thereafter could occur during the FDA’s review of our planned BLA for TA-ERT.

In addition, recently there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several 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 government payor programs, and review the relationship between pricing and manufacturer patient programs. For example, the Inflation Reduction Act of 2022 (“IRA”) among other things, (1) requires HHS to negotiate the price of certain single-source biologics that have been on the market for at least 11 years covered under Medicare as part of the Medicare Drug Price Negotiation Program (the “Medicare Drug Price Negotiation Program”), and (2) imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation on an annual basis. Each year up to twenty (20) products will be selected by HHS for the Medicare Drug Price Negotiation Program. Products subject to the Medicare Drug Price Negotiation Program are expected to experience a significant reduction in reimbursement from the Medicare program on a per unit basis.

HHS selected 10 products for 2026 and 15 products for each of 2027 and 2028, and may select up to 20 products per year beginning in 2029. Although the IRA, as amended by the “One Big Beautiful Bill Act” (“OBBBA”), excludes from negotiation certain drugs and biologics that are designated for, and approved only for, one or more rare diseases or conditions, and delays negotiation eligibility for such products until they no longer qualify for the exclusion, TA-ERT may not qualify for or maintain this exclusion, including if it is approved for additional indications, and the exclusion may be modified in the future. Products subject to the Medicare Drug Price Negotiation Program are expected to experience a significant reduction in reimbursement from the Medicare program on a per unit basis.

For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively the “Affordable Care Act”), was enacted in the United States. There have been executive, judicial and Congressional challenges to certain aspects of the Affordable Care Act. While Congress has not passed comprehensive repeal legislation, several bills affecting the implementation of certain taxes under the Affordable Care Act have been signed into law. For example, on August 16, 2022, the IRA was signed into law, which among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in Affordable Care Act marketplaces through plan year 2025. The IRA also eliminates the “donut hole” under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating a new manufacturer discount program. It is possible that the Affordable Care Act will be subject to judicial or Congressional challenges and amendments in the future. It is unclear how any such challenges and the healthcare reform measures of the second Trump administration will impact the Affordable Care Act and our business.

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. For example, on July 4, 2025, the annual reconciliation bill, the “One Big Beautiful Bill Act” (“OBBBA”) was signed into law which, is expected to reduce Medicaid spending and enrollment by implementing work requirements for some beneficiaries, capping state-directed payments, reducing federal funding, and limiting provider taxes used to fund the program. OBBBA also narrows access to ACA marketplace exchange enrollment and declines to extend the ACA enhanced advanced premium tax credits, set to expire at the end of 2025, which, among other provisions in the law, are anticipated to reduce the number of Americans with health insurance. Congress is considering proposed legislation intended to further reduce healthcare costs with alternatives to replace the expiring ACA subsidies.

Previous wording

The current administration is pursuing policies to reduce regulations and expenditures across government including at HHS, the FDA, the Centers for Medicare & Medicaid Services (“CMS”) and related agencies. These actions, presently directed by executive orders or memoranda from the Office of Management and Budget, may propose policy changes that create additional uncertainty for our business. For example, the current administration has announced agreements with certain pharmaceutical companies that require the drug manufacturers to offer, through a direct to consumer platform (“TrumpRx”), U.S. patients and Medicaid programs prescription drug Most-Favored Nation pricing equal to or lower than those paid in other developed nations, with additional mandates for direct-to-patient discounts and repatriation of foreign revenues. Other recent actions, for example, include (1) directives to reduce agency workforce and cut programs; (2) directing HHS and other agencies to lower prescription drug costs through a variety of initiatives, including by improving upon the Medicare Drug Price Negotiation Program and establishing Most-Favored-Nation pricing for pharmaceutical products; (3) imposing tariffs on certain imported pharmaceutical products; and (4) as part of the Make America Healthy Again (“MAHA”) Commission’s recent Strategy Report, working across government agencies to increase enforcement on direct-to-consumer pharmaceutical advertising. Additionally, the current administration recently called on Congress to enact “The Great Healthcare Plan,” to codify and expand Most-Favored Nation pricing, lower government subsidies to private insurance companies, increase healthcare price transparency, expand pharmaceutical drugs available for over-the-counter purchase, and enact restrictions on pharmacy benefit manager, or PBM, payment methodologies, among other things. These actions and policies may significantly reduce U.S. drug prices, potentially impacting manufacturers’ global pricing strategies and profitability, while increasing their operational costs and compliance risks. In June 2024, the U.S. Supreme Court’s Loper Bright Enterprises v. Raimondo decision greatly reduced judicial deference to regulatory agencies, which could increase successful legal challenges to federal regulations affecting our operations. Congress may introduce and ultimately pass health care related legislation that could impact the drug approval process and make changes to the Medicare Drug Price Negotiation Program created under the IRA. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our product candidates, if approved.

In addition, certain foreign activities related to drugs, biologics, and research, especially with regard to China, have come under increased scrutiny in the United States. Chinese contract manufacturing organizations may become subject to legislation, trade restrictions, sanctions, tariffs and other regulatory requirements by the U.S. government, which could restrict or even prohibit our ability to work with such entities. For example, on December 18, 2025, President Trump signed the National Defense Authorization Act for Fiscal Year 2026 (“NDAA”) into law. On June 8, 2024, the Department of Defense released the annual 1260H List which included a number of contract manufactures, making them biotechnology companies of concern. The BIOSECURE Act prohibits U.S. federal agencies from entering into or renewing any contract, loan, or grant with any entity that uses biotechnology equipment or services produced or provided by a “biotechnology company of concern” to perform that contract. The BIOSECURE Act also prohibits U.S. government loan and grant recipients from using federal loan or grant money to enter into contracts with entities that use equipment from “biotechnology companies of concern” in the performance of any federal prime contract or subcontract. The Office of Management and Budget (“OMB”) of the U.S. Government will issue a list of “biotechnology companies of concern,” which will include certain companies that are identified on the U.S. Department of Defense’s annual List of Chinese Military Companies, also known as the 1260H List, other entities which the U.S. Government has deemed as such pursuant to a separate designation process, and certain subsidiary, parent, and successor entities of the foregoing. The BIOSECURE Act includes a safe harbor provision providing that the restrictions do not apply to equipment or services that were formerly but are no longer provided by a “biotechnology company of concern.” The BIOSECURE Act also includes a grandfathering provision providing that the prohibitions shall not apply for a five-year period to biotechnology equipment or services produced or provided under a contract or agreement entered into before the applicable effective date. Under the NDAA BIOSECURE Act related language we may be restricted in our ability to work with certain Chinese biotechnology manufacturing companies to the extent we would contract with, or otherwise receive funding from, the U.S. government. In addition, if we, our suppliers, or our customers were to be designated under the NDAA BIOSECURE Act related language, this could potentially cause harm to our business, financial condition, results of operations and prospects.

Moreover, in order to obtain reimbursement for our products in some European countries, including some EU Member States, we may be required to compile additional data comparing the cost-effectiveness of our products to other available therapies. The Health Technology Assessment (“HTA”) of medicinal products is becoming an increasingly common part of the pricing and reimbursement procedures in some EU Member States, including those representing the larger markets. The HTA process is the procedure to assess therapeutic, economic and societal impact of a given medicinal product in the national healthcare systems of the individual country. The outcome of an HTA will often influence the pricing and reimbursement status granted to these medicinal products by the competent authorities of individual EU Member States. The extent to which pricing and reimbursement decisions are influenced by the HTA of the specific medicinal product currently varies between EU Member States. In December 2021, Regulation No 2021/2282 on HTA, amending Directive 2011/24/EU, was adopted in the EU. This Regulation, which entered into force in January 2022, began to apply on January 12, 2025 through a phased implementation. The Regulation initially applies to new active substances for oncology and advanced therapy medicinal products. It will be expanded to orphan medicinal products in January 2028, and to all centrally authorized medicinal products as of 2030. Select high-risk medical devices will also come into scope in 2026. It is intended to boost cooperation among EU Member States in assessing health technologies, including new medicinal products, and providing the basis for cooperation at EU level for joint clinical assessments in these areas. The Regulation permits EU Member States to use common HTA tools, methodologies, and procedures across the EU to identify promising technologies early, and continuing voluntary cooperation in other areas. Individual EU Member States will continue to be responsible for assessing non-clinical (e.g., economic, social, ethical) aspects of health technologies, and making decisions on pricing and reimbursement. If we are unable to maintain favorable pricing and reimbursement status in EU Member States for product candidates that we may successfully develop and for which we may obtain regulatory approval, any anticipated revenue from and growth prospects for those products in the EU could be negatively affected.

In addition, on December 11, 2025, the European Commission, the Parliament and the European Council reached a political agreement on a comprehensive overhaul of EU pharmaceutical legislation (the “Pharma Package”). The reform has been under negotiation since the European Commission submitted its proposal in April 2023. This package—comprised of a new directive and regulation to replace existing legislation—aims to modernize the EU framework. The political agreement is still subject to formal approval by the European Parliament and Council. If approved in the form proposed, the Pharma Package will, among other changes, reduce the baseline market protection period by one year, with limited opportunities for extensions, capped at a maximum of eleven years. The reform will also significantly reshape the incentives regime for orphan medicinal products, by introducing “breakthrough” orphan medicinal products – those addressing diseases with no available medicinal treatment – which will benefit from 11 years of market exclusivity. A decrease in market exclusivity opportunities for our product candidates in the EU could impact the commercial prospects of our product candidates.

The reform has been under negotiation since the European Commission submitted its proposal in April 2023. The Pharma Package, comprised of a new directive and regulation to replace existing legislation, aims to modernize the EU framework. The Council formally adopted its first-reading position on the Pharma Package on September 28, 2026. The legislation is still subject to formal approval by the European Parliament, following which it will be published in the Official Journal of the European Union and enter into force. The Pharma Package encompasses a broad range of measures, including changes to regulatory data and market protection periods, including an eight-year regulatory data protection period and a one-year market protection period, with opportunities for additional periods of market protection subject to specified conditions and a maximum combined regulatory protection period of eleven years; changes to the orphan medicinal product framework, including a reduction in the standard period of orphan market exclusivity from ten to nine years, an eleven-year period of orphan market exclusivity for certain “breakthrough” orphan medicinal products, and changes to the incentives available for additional orphan indications; and an expansion of the “Bolar” exemption to permit certain activities relating to generic and biosimilar medicines while relevant intellectual property rights remain in force, including submissions for procurement tenders. A decrease in market exclusivity opportunities for our product candidates in the EU, combined with the expanded Bolar exemption, could open them to generic or biosimilar competition earlier than under the current regime, potentially impacting reimbursement status and the commercial prospects of our product candidates. A decrease in market exclusivity opportunities for our product candidates in the EU could impact the commercial prospects of our product candidates.

In order to market and sell our product candidates in other jurisdictions, we must obtain separate marketing approvals for those jurisdictions and comply with their numerous and varying regulatory requirements. We may not obtain foreign regulatory approvals on a timely basis, or at all. The approval procedure varies among countries and can involve additional testing. The time required to obtain approval may differ substantially from that required to obtain FDA approval. The regulatory approval process outside the United States generally includes all of the risks associated with obtaining FDA approval. In addition, in many countries outside the United States, product reimbursement approvals must be secured before regulatory authorities will approve the product for sale in that country. Obtaining foreign regulatory approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our product candidates in certain countries. Further, clinical trials conducted in one country may not be accepted by regulatory authorities in other countries and regulatory approval in one country does not ensure approval in any other country, while a failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory approval process in others. Our failure to obtain approval of our product candidates by foreign regulatory authorities may negatively impact the commercial prospects of such product candidates and our business prospects could decline. Also, if regulatory approval for our product candidates is granted, it may be later withdrawn. If we fail to comply with the regulatory requirements in international jurisdictions and receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential for our product candidates will be harmed and our business may be adversely affected.

We intend to seek to in-license or acquire development and commercial-stage product candidates in disorders that have the potential to complement our existing portfolio. Our current product candidates are generally in-licensed from or derived from partnerships with other pharmaceutical companies. If we decide to pursue the development and commercialization of any additional product candidates, we may be required to invest significant resources to acquire or in-license the rights to such product candidates or to conduct drug discovery activities and we may be unable to in-license the rights on reasonable terms if at all. We do not currently have the necessary drug discovery personnel or expertise adequate to discover and develop an additional product candidate on our own. Any other product candidates will require additional, time-consuming development efforts, and significant financial resources, prior to commercial sale, including preclinical studies, extensive clinical trials, and approval by the FDA and applicable foreign regulatory authorities. All product candidates are prone to the risks of failure that are inherent in pharmaceutical product development, including the possibility that the product candidate will not be shown to be sufficiently safe and/or effective for approval by regulatory authorities. In addition, we may not be able to acquire, discover, or develop any additional product candidates, and any additional product candidates we may develop may not be approved, manufactured, or produced economically, successfully commercialized or widely accepted in the marketplace, or be more effective than other commercially available alternatives. Research programs to identify new product candidates require substantial technical, financial, and human resources whether or not we ultimately identify any candidates. If we are unable to develop or commercialize any other product candidates, our business, financial condition, results of operations and prospects will suffer.

For a description of the Avenue Loan Agreement and the Avenue Amendment, see Note 6, “Debt — Avenue Loan,” and Note 13, “Subsequent Events—Amendment to Avenue Loan Agreement,” financial statements included elsewhere in this Quarterly Report.

Previous wording

The Avenue Loan Agreement contains customary representations, warranties and covenants, including covenants by the company limiting, amongst other things, additional indebtedness, liens, guaranties, mergers and consolidations, substantial asset sales, investments and loans, certain corporate changes, transactions with affiliates and fundamental changes. These covenants may limit our ability to engage in certain transactions that may be in our long-term best interest, including entering into a change in control transaction. While we have not previously breached and are currently in compliance with the covenants contained in the Loan Agreement, we may breach these covenants in the future. Our ability to comply with these covenants may be affected by events and factors beyond our control. In the event that we breach one or more covenants, the Agent may choose to declare an event of default and require that we immediately repay all amounts outstanding under the Loan Agreement, terminate any commitment to extend further credit and foreclose on the collateral.

Tranche 3 or the Discretionary Tranche 4 is subject to the Lender’s approval. On April 22, 2026, we closed our previously announced underwritten public offering of 1,150,000 shares of our common stock and pre-funded warrants to purchase up to 50,000 shares of our common stock, and we granted the underwriters a 30-day option to purchase up to 180,000 additional shares of common stock, which was exercised in full. The net proceeds to us from the offering were $64.4 million. Additionally, in August 2026 we completed a private placement for net proceeds of $5.5 million.

Lender may also elect to convert up to $4.0 million of the principal amount outstanding under the Avenue Loan Agreement into shares of our common stock at a price of $60.00 per share. In August 2026, we entered into a stock purchase agreement pursuant to which we agreed to sell and issue 121,203 shares of common stock in a private placement transaction. If these additional shares of common stock, and the shares of common stock issued or issuable pursuant to such pre-funded warrants and warrants, are resold, or if it is perceived that they will be resold, in the public market, the trading price of our common stock could decline.
