    CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

     

    Statements made in this Quarterly Report on Form 10-Q that are not statements of historical or current facts are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended. Forward-looking statements discuss our business, operations and financial performance and conditions, as well as our plans, objectives and expectations for our business operations and financial performance and condition. In some cases, you can identify forward-looking statements by terminology such as “aim,” “anticipate,” “assume,” “believe,” “contemplate,” “continue,” “could,” “design,” “due,” “estimate,” “expect,” “goal,” “intend,” “may,” “objective,” “plan,” “predict,” “positioned,” “potential,” “seek,” “should,” “target,” “will,” “would” and other similar expressions that are predictions of or indicate future events and future trends, or the negative of these terms or other comparable terminology. In addition, statements that “we believe” or similar statements reflect our beliefs and opinions on the relevant subject only. These forward-looking statements, which are subject to risks, uncertainties and assumptions about us, may include projections of our future financial performance, our anticipated growth strategies and anticipated trends in our business.

    You should understand that the following important factors could affect our future results and could cause those results or other outcomes to differ materially from those expressed or implied in our forward-looking statements:

    •
    uncertainties in obtaining successful non-clinical or clinical results that reliably and meaningfully demonstrate safety, tolerability and efficacy profiles that are satisfactory to the U.S. Food and Drug Administration (“FDA”), European Medicines Agency ("EMA") and other comparable regulatory authorities for marketing approval for nomlabofusp (nomlabofusp is the International Nonproprietary Name and the United States Adopted Name for CTI-1601 ) or any other product candidates that we may develop in the future and unexpected costs that may result therefrom;
    •
    delays in patient recruitment for our clinical trials (including as a result of the impact of FDA approval of competitive products for the treatment of Friedreich's ataxia ("FA"), and/or the impact of other clinical trials of competitive products), delays as a result of clinical and non-clinical results and/or FDA's request for additional information or studies (whether clinical or non-clinical), changes in clinical protocols, adverse events, regulatory restrictions, including additional clinical holds, and milestones for nomlabofusp;
    •
    our ability to successfully execute our ongoing open label extension trial (“OLE”) and our pediatric PK run-in trial, including the timing of site initiations and the rate of patient enrollment;
    •
    our ability to benefit from participating in the FDA’s Support for Clinical Trials Advancing Rare Disease Therapeutics (“START”) pilot program for the development of nomlabofusp;
    •
    uncertainties associated with the clinical development and regulatory approval for nomlabofusp, including potential delays in the commencement, enrollment and completion of clinical trials, the timing of a potential Biologics License Application (“BLA”) submission for accelerated approval, including our ability to supply to the FDA all required data for the FDA to review and accept an accelerated application, or any other product candidates that we may develop in the future;
    •
    the difficulties and expenses associated with obtaining and maintaining regulatory approval for nomlabofusp or any other product candidates we may develop in the future, and the indication and labeling under any such approval;
    •
    how long we can continue to fund our operations with our existing cash, cash equivalents and marketable securities and our estimates regarding future results of operations, financial position, research and development costs, capital requirements and our access and needs for additional financing;
    •
    our expectations regarding the use of proceeds from future financings, if any;
    •
    our ability, and the ability of third-party manufacturers we engage, to optimize, scale and validate nomlabofusp or any other product candidate’s manufacturing process and to manufacture sufficient quantities of clinical supplies, and, if approved, commercial supplies of nomlabofusp or any other

     


     

    product candidates that we may develop in the future and our ability to maintain our relationships and contracts with our key vendors and to identify and contract with alternate or secondary key vendors;
    •
    our ability to realize any value from nomlabofusp and/or any other product candidates we may develop in the future in light of inherent risks and difficulties involved in successfully bringing product candidates to market and the risk that the product candidates, if approved, will not achieve broad market acceptance;
    •
    our ability to comply with regulatory requirements applicable to our business and other regulatory developments in the United States and other countries;
    •
    the size and growth of the potential markets for nomlabofusp, if approved, or any other product candidates that we may develop in the future, the rate and degree of market acceptance of nomlabofusp or any other product candidate, if approved, that we may develop in the future and our ability to serve those markets;

    LARIMAR THERAPEUTICS, INC.

    NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

    (Unaudited)

    1.
    Description of Business and Basis of Presentation

    Larimar Therapeutics, Inc., together with its subsidiary (the “Company” or “Larimar”), is a clinical-stage biotechnology company focused on developing treatments for patients suffering from complex rare diseases using its novel cell penetrating peptide technology platform. Larimar's lead product candidate, nomlabofusp (nomlabofusp is the International Nonproprietary Name and the United States Adopted Name for CTI-1601), is a subcutaneously administered, recombinant fusion protein intended to deliver human frataxin ("FXN"), an essential protein, to the mitochondria of patients with Friedreich’s ataxia ("FA"). FA is a rare, progressive and fatal disease in which patients are unable to produce sufficient FXN due to a genetic abnormality.

    Larimar has completed two Phase 1 clinical trials and a Phase 2 dose exploration trial, and has an ongoing Phase 2 OLE trial in patients with FA and an ongoing run-in study in adolescent patients with FA.

    In May 2021, the Company reported positive top-line data from its Phase 1 FA program after completing dosing of the single ascending dose ("SAD") trial in December 2020 and of the multiple ascending dose ("MAD") trial in March 2021. Data from these trials demonstrated proof-of-concept by showing that daily subcutaneous injections of nomlabofusp for up to 13 days resulted in dose-dependent increases in FXN levels from baseline compared to placebo in all evaluated tissues (buccal cells, skin, and platelets). There were no serious adverse events associated with either the MAD or SAD trials.

    In May 2023, the Company reported preliminary unblinded top-line data from the 25 mg cohort of the Phase 2 four-week, placebo-controlled, dose exploration trial of nomlabofusp in FA patients. Data from the cohort indicated nomlabofusp was generally well tolerated and showed increases in FXN levels from baseline compared to placebo in all evaluated tissues (skin and buccal cells) at day 14.

    In July 2023, the FDA cleared initiation of a second cohort (50 mg) of the four-week, placebo-controlled, Phase 2 dose exploration trial of nomlabofusp in patients with FA and the initiation of the OLE trial with daily dosing of 25 mg.

    In February 2024, the Company reported positive top-line data and successful completion of the Phase 2 dose exploration study. Nomlabofusp was generally well tolerated throughout the four-week treatment periods, had a predictable pharmacokinetic profile and led to dose dependent increases in FXN levels in all evaluated tissues (skin and buccal cells) after daily dosing of 14 days followed by every other day dosing until day 28 in the 25 mg and 50 mg cohorts. Participants in the 25 mg (n=13) and 50 mg (n=15) cohorts were randomized 2:1 to receive subcutaneous injections of nomlabofusp or placebo. Patients who completed treatment in the Phase 2 dose exploration study or who previously completed a prior clinical trial of nomlabofusp are eligible to screen and possibly participate in the OLE study.

    In March 2024, Larimar dosed the first patient in the OLE trial, evaluating daily subcutaneous injections of 25 mg of nomlabofusp self-administered or administered by a caregiver. The OLE study will evaluate the safety and tolerability, pharmacokinetics, and frataxin levels in peripheral tissues as well as other exploratory pharmacodynamic markers (lipid profiles and gene expression data) following long-term subcutaneous administration of nomlabofusp. In addition, following the completion of enrollment, as well as at least one participant completing one year of dosing, clinical assessments collected during the study will be compared to data from a matched control arm derived from participants in the Friedreich’s Ataxia Clinical Outcome Measures Study ("FACOMS") database.

    On May 30, 2024, Larimar announced that the FDA's Center for Drug Evaluation and Research ("CDER") had selected nomlabofusp as one of a few programs for participation in the Support for Clinical Trials Advancing Rare Disease Therapeutics ("START") Pilot Program. The objective of the program is to accelerate the development of drugs for rare diseases that lead to significant disability or death by facilitating frequent advice and regular communication with the FDA staff to expedite the review process of biologics and drugs.

    In September 2024, the Company received access to the Medicines and Healthcare Regulatory Agency ("MHRA”) Innovative Licensing and Access Pathway (“ILAP”) for the treatment of adults and children with FA. The ILAP is facilitating patient access to novel treatments by accelerating time to market through opportunities for enhanced engagements with UK regulatory authorities and other stakeholders. Along with the receipt of the ILAP designation, nomlabofusp has already been granted orphan drug designations in the U.S. and the European Union (the “EU”), and access to the PRIME scheme in the EU.

    In December 2024, the Company reported positive initial data from the ongoing OLE study. This data included safety, FXN levels, clinical, pharmacokinetic data and dose escalation:

    7


     

    •
    Nomlabofusp was generally well tolerated for up to 260 days in subjects. The most common adverse events were injection site reactions, with most being mild, brief in duration, and self-limited. Two participants had serious adverse events (one seizure and one anaphylactic reaction) that resolved within 24 hours and withdrew from the study;
    •
    Long-term 25 mg tissue FXN levels showed positive mean change from baseline of 1.32 pg/μg in buccal cells and 9.28 pg/μg in skin cells at Day 90 and that 25 mg of nomlabofusp increased and maintained tissue FXN levels over time, increasing from a mean level of 15% of HV at baseline to 30% in buccal cells and from 16% to 72% in skin cells at Day 90;
    •
    Tissue FXN levels appear to reach steady-state levels by Day 30 in buccal cells;
    •
    Early clinical data showed trends toward improvement across a number of clinical outcomes for long-term 25 mg daily nomlabofusp including: (1) decreased values indicating early trends towards improvement in the Modified Friedreich's Ataxia Rating Scale (mFARS) and the FARS-Activities of Daily Living ("ADL"), Modified Fatigue Impact Scale and 9 hole peg test at 90 days relative to baseline;
    •
    Key pharmacokinetic data showed rapid absorption after subcutaneous administration with exposure appearing to reach steady state in plasma by day 30 with no further accumulation, which is consistent with data from our Phase 1 and Phase 2 studies.

    Also in December 2024, Larimar announced that it was increasing the dose in the OLE to 50 mg of nomlabofusp daily for then currently enrolled and all future OLE study participants. In March 2025, the Company announced that its Safety Monitoring Team has deemed anaphylaxis as an adverse drug reaction likely associated with nomlabofusp and therefore, Larimar expects to see additional reactions. To reduce the risk of allergic reactions, including anaphylaxis, Larimar amended the OLE protocol to administer premedication for the first month of dosing. The OLE study is ongoing with seven sites activated and participants continuing to enroll. Active study participants are currently receiving the 50 mg dose of nomlabofusp. The Company plans to provide an update on OLE data on at least 30 to 40 study participants, some of whom have been receiving nomlabofusp for more than a year, in September 2025.

    In January 2025, the Company initiated dosing of adolescents (12-17 years old) in a pharmacokinetic ("PK") run-in study for pediatric patients with FA. Study participants in the PK run-in study were randomized 2:1 to receive either nomlabofusp at a weight-base dose expected to match the PK of adults receiving the 50 mg dose, or placebo, daily for seven days. Dosing of this adolescent PK run-in study was completed in March 2025. Following assessment of safety and PK data, participants will be eligible to screen for the OLE study. The data from this cohort is expected to be presented in the nomlabofusp program update in September 2025.

    In February 2025, FDA accepted the data supporting the comparability of the lyophilized drug product to the frozen solution and agreed with Larimar’s plans to introduce the lyophilized product into its clinical development program in mid-2025. The frozen solution is the dosage form currently being used in the OLE. The lyophilized drug product is the formulation that Larimar intends to commercialize.

    In March 2025, the Company announced that FDA stated as part of a START pilot program that it is open to considering the use of FXN concentration as a reasonably likely surrogate endpoint (“RLSE”) and the acceptability of FXN’s concentration as an RLSE to support approval will be a matter of review in a future marketing application. FDA recommended focusing on assessments of skin FXN concentrations rather than buccal FXN concentrations due to more consistent sampling and less variability. FDA acknowledged that data the Company recently submitted appear to support a relationship between increased FXN concentrations in skin cells and relevant tissues such as the heart, dorsal root ganglion and skeletal muscle. FDA also acknowledged that the nonclinical studies the Company submitted were performed at relevant human doses. FDA also suggested that the Company consider exploring the relationship between increases in FXN in skin and changes in pharmacodynamic (PD) markers such as lipid profiles and/or clinical measures to provide additional support for the use of FXN as an RLSE. The Company continues to interact with the FDA under the START pilot program, including seeking feedback on the adequacy of the safety data set for a BLA submission seeking accelerated approval targeted for the end of 2025.

    Additionally, the Company has obtained feedback from both FDA and EMA on the global Phase 3 study protocol, and the Company is on track to initiate the study by mid-2025 with potential sites in the U.S., E.U., U.K, Canada, and Australia.

    The Company is subject to risks and uncertainties common to pre-commercial companies in the biotechnology industry, including, but not limited to, development and commercialization by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with governmental regulations, failure to secure regulatory approval for its drug candidates or any other product candidates and the ability to secure additional capital to fund its operations. Product candidates under development will require extensive non-clinical and clinical testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel, infrastructure and extensive compliance-reporting

    8


     

    capabilities. Even if the Company's drug development efforts are successful, it is uncertain when, if ever, it will realize significant revenue from product sales.

    Basis of Presentation

    The condensed consolidated financial statements include the accounts of Larimar and its wholly owned subsidiary. All intercompany balances and transactions have been eliminated. The accompanying condensed consolidated financial statements have been prepared in conformity with U.S. Generally Accepted Accounting Principles ("GAAP").

    The condensed consolidated balance sheet as of December 31, 2024 was derived from the Company’s audited financial statements but does not include all disclosures required by GAAP. The accompanying unaudited condensed consolidated financial statements as of March 31, 2025 and for the three months ended March 31, 2025 and 2024, have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2024 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 24, 2025.

    In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the Company’s condensed consolidated financial position as of March 31, 2025, condensed consolidated results of operations for the three months ended March 31, 2025 and condensed consolidated statement of cash flows for the three months ended March 31, 2025 have been made. The results of operations for the three months ended March 31, 2025 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2025.

    Liquidity and Capital Resources

    The Company’s condensed consolidated financial statements have been presented on the basis that it will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business.

    Since its inception, the Company has incurred significant recurring operating losses and negative cash flows from operations. The Company has incurred net losses of $29.3 million and $14.7 million for the three months ended March 31, 2025 and 2024, respectively. In addition, as of March 31, 2025, the Company had an accumulated deficit of $298.4 million. The Company expects to continue to generate operating losses for the foreseeable future. As of March 31, 2025, the Company had approximately $157.5 million of cash, cash equivalents and marketable securities available for use to fund its operations and capital requirements.

    The Company has funded its operations to date primarily with proceeds from sales of common stock and proceeds from the sale of prefunded warrants for the purchase of common stock, the acquisition in 2020 of cash, cash equivalents and marketable securities upon the merger with Zafgen, Inc. ("Zafgen") and, prior to the 2020 merger with Zafgen, capital contributions from Chondrial Holdings, LLC.

    In accordance with Accounting Standards Update (“ASU”) No. 2014-15, "Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern", the Company has evaluated whether there are certain conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that these condensed consolidated financial statements are issued. As of the issuance date of these condensed consolidated financial statements, the Company expects its cash, cash equivalents and marketable securities will be sufficient to fund its forecasted operating expenses and capital expenditure requirements for at least twelve months from the date these financial statements are issued, into the second quarter of 2026. If the timing of the Company's clinical assumptions are delayed or if there are other forecasted assumption changes that negatively impact its operating plan, the Company would reduce expenditures in order to further extend cash resources.

    The Company has not yet commercialized any products and does not expect to generate revenue from the commercial sale of any products for several years, if at all. The Company expects that its research and development and general and administrative expenses will continue to increase and, as a result, that it will need additional capital

    9


     

    to fund its future operating and capital requirements. Unless and until the Company can generate substantial revenue, management continuously evaluates different strategies to obtain the required funding for future operations. These strategies include seeking additional funding through a combination of public or private equity offerings, debt or royalty financings, collaborations and licensing arrangements, strategic partnerships with pharmaceutical and/or larger biotechnology companies, or other sources. The incurrence of indebtedness would result in increased fixed payment obligations and the Company may be required to agree to certain restrictive covenants, such as limitations on its ability to incur additional debt, limitations on its ability to acquire, sell or license intellectual property rights, minimum required cash balances and other operating restrictions that could adversely impact the Company's ability to conduct its business. Any additional fundraising efforts may divert the Company's management from their day-to-day activities, which may adversely affect its ability to develop and commercialize its product candidates.

    There can be no assurance that the Company will be able to raise sufficient additional capital on acceptable terms, if at all. If such additional financing is not available on satisfactory terms, or is not available in sufficient amounts, or if the Company does not have sufficient authorized shares, the Company may be required to delay, limit, or eliminate the development of business opportunities and its ability to achieve its business objectives, its competitiveness, and its business, financial condition, and results of operations will be materially adversely affected. The Company could also be required to seek funds through arrangements with collaborative partners or otherwise at an earlier stage than otherwise would be desirable and it may be required to relinquish rights to some of its technologies or product candidates or otherwise agree to terms unfavorable to it, any of which may have a material adverse effect on the Company's business, operating results and prospects. In addition, geopolitical tensions, volatility of capital markets, and other adverse macroeconomic events, including those due to inflationary pressures, rising interest rates, bank instability and the ability of the U.S. government to manage federal debt limits as well as the potential impact of other health crises on the global financial markets may reduce the Company's ability to access capital, which could negatively affect its liquidity and ability to continue as a going concern.

    If the Company is unable to obtain sufficient funding when needed and/or on acceptable terms, the Company may be required to significantly curtail, delay or discontinue one or more of its research and development programs, the manufacture of clinical and commercial supplies, product portfolio expansion, commercialization efforts and/or commercial operations, which could adversely affect its business prospects, or the Company may be unable to continue operations.

    2.
    Summary of Significant Accounting Policies

    Use of Estimates

    The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. This process involves reviewing open contracts and purchase orders, communicating with our personnel and outside vendors to identify services that have been performed on our behalf and estimating the level of service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the accrual of research and development expense, the recording as prepaid expense of payments made in advance of the actual provision of goods or services, valuation of stock-based awards and valuation of leases. Due to inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in these estimates. On an ongoing basis, the Company evaluates its estimates and assumptions.

    Research and Development Costs

    Costs associated with internal research and development and external research and development services, including drug development, clinical studies and non-clinical studies, are expensed as incurred. Research and development expenses include costs for salaries, employee benefits, subcontractors, facility-related expenses, depreciation, stock-based compensation, third-party license fees, laboratory supplies, and external costs of outside vendors engaged to conduct discovery, non-clinical and clinical development activities and clinical trials as well as to manufacture clinical trial materials, and other costs. The Company recognizes external research and development costs based on an evaluation of the progress to completion of specific tasks using information provided to the Company by its key service providers.

    10


     

    Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. Such prepaid expenses are recognized as an expense when the goods have been delivered or the related services have been performed, or when it is no longer expected that the goods will be delivered, or the services rendered.

    Upfront payments, milestone payments and annual maintenance fees under license agreements are currently expensed in the period in which they are incurred.

    Patent Costs

    All patent-related costs incurred in connection with filing and prosecuting patent applications are expensed as incurred due to the uncertainty about the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses.

    Stock-Based Compensation

    The Company measures all stock-based awards granted to employees and directors based on the fair value on the date of grant using the Black-Scholes option-pricing model. Compensation expense of those awards is recognized over the requisite service period, which is the vesting period of the respective award. Typically, the Company issues awards with only service-based vesting conditions and records the expense for these awards using the straight-line method. The Company accounts for forfeitures as they occur.

    The Company classifies stock-based compensation expense in its consolidated statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

    Prior to May 28, 2020, the Company had been a private company and lacked company-specific historical and implied volatility information for its common stock. Prior to January 1, 2023, the Company estimated its expected common stock price volatility solely based on the historical volatility of publicly traded peer companies. Beginning on January 1, 2023, based on the availability of sufficient historical trading data of the Company's own common stock on the Nasdaq Global Market to calculate accurately its volatility, the Company began blending its volatility starting from June 2020 (following its merger with Zafgen in 2020) to the date of each stock-based award, and weighing the volatility of its peer group for the amount of time from May 31, 2020 backwards so that the blended volatility equals the expected term of the related stock-based award. The expected term of the Company’s stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield considers the fact that the Company has never paid cash dividends on common stock and does not expect to pay any cash dividends in the foreseeable future.

    Net Loss Per Share

    Basic net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period.

    Diluted net loss per share attributable to common stockholders is computed by dividing the diluted net loss attributable to common stockholders by the weighted average number of common shares, including potentially dilutive common stock equivalents assuming the dilutive effect of outstanding stock options, outstanding restricted stock units, and unvested restricted common shares, as determined using the treasury stock method. For periods in which the Company has reported net losses (all periods since inception), diluted net loss per common share attributable to common stockholders is the same as basic net loss per common share attributable to common stockholders, since dilutive common stock equivalents are not assumed to have been issued if their effect is antidilutive.

    The Company excluded 9,564,550 and 6,555,145 common stock equivalents outstanding as of March 31, 2025 and 2024, respectively, from the computation of diluted net loss per share for the three months ended March 31, 2025 and 2024 because they had an anti-dilutive impact due to the net loss incurred for the periods presented.

    Segment Information

    Operating segments are defined as components of an enterprise for which separate discrete information is available for evaluation by the chief operating decision maker, or decision making group, in deciding how to

    11


     

    allocate resources in assessing performance. The Company is managed on a consolidated basis and has one operating and reportable segment related to the development of clinical and preclinical product candidates for the development of the Company’s proprietary new therapies, primarily nomlabofusp, the Company's life science segment. The Company’s chief operating decision maker (“CODM”) is the Company's chief executive officer ("CEO").

    The accounting policies of the life science segment are the same as those described in the summary of significant accounting policies. The CODM assesses performance for the Company and its reportable segment based on net loss, which is reported on the consolidated Statements of Operations. The measure of segment assets is reported on the balance sheet as total consolidated assets. All long-lived assets are located in the U.S.

    To date, the Company has not generated any product revenue. The Company expects to continue to incur significant expenses and operating losses for the foreseeable future as it advances product candidates through all stages of development and clinical trials and regulatory approval.

    The CODM uses consolidated financial information, including consolidated net loss, to evaluate performance, forecast future period financial results, allocate resources for the company by, among other things, comparing budgeted to actual results.

    The table below summarizes the significant expense categories regularly provided to the CODM for the three months ended March 31, 2025 and 2024:

    Recently Issued and Adopted Accounting Pronouncements

    From time to time, new accounting guidance is issued by the FASB or other standard setting bodies that is adopted by us as of the effective date or, in some cases where early adoption is permitted, in advance of the effective date. We have assessed the recently issued guidance that is not yet effective and believe the new guidance will not have a material impact on the consolidated results of operations, cash flows or financial position.

    In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 requires disclosure of incremental segment information on an annual and interim basis. The amendments also require companies with a single reportable segment to provide all disclosures required by this amendment and all existing segment disclosures in ASC 280, Segment Reporting. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods beginning after December 15, 2024. The Company adopted ASU 2023-07, effective December 31, 2024, in these consolidated financial statements. ASU 2023-07 only impacted the disclosures and did not impact the consolidated financial statements. See Note 2, Segment Information, for disclosures related to the adoption of ASU 2023-07.

    Recently Issued Accounting Pronouncements Not Yet Adopted

    In December 2023, the FASB issued ASU No. 2023-09, “Improvements to Income Tax Disclosures (Topic 740),” which requires entities to disclose in their rate reconciliation table additional categories of information about federal, state and foreign income taxes as well as additional information about reconciling items if certain

    12


     

    quantitative thresholds are met. This ASU will require all entities to disclose income taxes paid, net of refunds, disaggregated by federal (national), state and foreign taxes for annual periods and to disaggregate the information by jurisdiction based on a quantitative threshold. All entities are required to apply the guidance prospectively, with the option to apply it retrospectively. The ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company has determined it will adopt this ASU on January 1, 2025, the adoption of which is not expected to have a material impact on the Company’s consolidated results of operations or cash flows.

    In November 2024, the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, which requires disaggregated disclosures in the notes of the financial statements of certain categories of expenses that are included in expense line items on the face of the income statement. This ASU is effective for annual periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company will evaluate the impact adopting ASU 2024-03 will have on the Company's consolidated financial statements and disclosures.

    Fair Value Measurements and Marketable Securities

    Fair Value Measurements

    The Company’s assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2025 and December 31, 2024 are measured in accordance with the standards of ASC 820, "Fair Value Measurements and Disclosures", which establishes a three-level valuation hierarchy for measuring fair value and expands financial statement disclosures about fair value measurements. The valuation hierarchy is based on the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:

     

    Level – 1

    Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

     

     

    Level – 2

    Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

     

     

    Level – 3

    Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

    The Company’s financial instruments consist primarily of cash, cash equivalents, marketable securities, accounts payable and accrued liabilities. For accounts payable and accrued liabilities, the carrying amounts of these financial instruments as of March 31, 2025 and December 31, 2024 were considered representative of their fair values due to their short term to maturity.

    The accrued interest receivable related to the Company’s investments was $1.1 million as of March 31, 2025 and December 31, 2024, respectively, and is included in prepaid expenses and other current assets on the condensed consolidated balance sheets.

    The Company classifies its money market funds and U.S. treasury bills, which are valued based on quoted market prices in active markets with no valuation adjustment, as Level 1 assets within the fair value hierarchy.

    The Company classifies its investments in U.S. government and agency securities, corporate commercial paper, and corporate bonds, if any, as Level 2 assets within the fair value hierarchy. The fair values of these investments are estimated by taking into consideration valuations obtained from third-party pricing services. The pricing services utilize industry standard valuation models, including both income- and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker/dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities, prepayment/default projections based on historical data and other observable inputs.

    As of March 31, 2025 and December 31, 2024, the unrealized losses for available-for-sale investments were non-credit related, and the Company does not intend to sell the investments that were in an unrealized loss position, nor will it be required to sell those investments before recovery of their amortized cost basis, which may be maturity. As of March 31, 2025 and December 31, 2024, no allowances for credit losses for the Company’s

    14


     

    investments were recorded. During the three months ended March 31, 2025 and 2024, the Company did not recognize any impairment losses related to investments.

    As of March 31, 2025 and December 31, 2024, the Company's cash equivalents and marketable securities consisted of a U.S. government money market fund, U.S. Treasury Bills and U.S. government and agency securities, all held in our name in a separate custody account with U.S. Bank. The U.S. government money market fund has same-day liquidity access and the U.S. government and agency securities all have maturities of 360 days or less.

    Stockholders’ Equity and Stock Options

    Common Stock and Prefunded Warrants

    On May 28, 2020, the Company entered into a securities purchase agreement with certain accredited investors (the “Purchasers”) for the sale by the Company in a private placement of 6,105,359 shares of the Company’s common stock and prefunded warrants to purchase an aggregate of 628,403 shares of the Company’s common stock, for a price of $11.88 per share of the common stock and $11.87 per prefunded warrant. The prefunded warrants were exercisable at an exercise price of $0.01 and were exercisable indefinitely. In August 2023, the 628,403 shares of prefunded warrants were exercised and the Company received cash proceeds of six thousand two hundred and eighty-four dollars. The private placement closed on June 1, 2020. The aggregate gross proceeds for the issuance and sale of the common stock and prefunded warrants were $80.0 million, transaction costs totaled $4.6 million and resulted in net proceeds of $75.4 million. The Company’s Registration Statement on Form S-3, filed with the SEC on June 26, 2020, registered the resale of 6,105,359 shares of common stock sold and the 628,403 shares of common stock underlying the prefunded warrants. MTS Health Partners served as placement agent to the Company in connection with the private placement. As partial compensation for these services, the Company issued MTS Health Partners 35,260 shares of common stock.

    As of March 31, 2025, the Company’s Ninth Amended and Restated Certificate of Incorporation, as amended, authorized the Company to issue up to 115,000,000 shares of common stock, par value $0.001 per share, of which 64,027,892 shares were issued and outstanding, and up to 5,000,000 shares of undesignated preferred stock, par value $0.001 per share, of which no shares were issued or outstanding. The voting, dividend and liquidation rights of the holders of the Company’s common stock are subject to and qualified by the rights, powers and preferences of the holders of the preferred stock. Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders. Common stockholders are entitled to receive dividends, as may be declared by the board of directors of the Company (the “Board”), if any. No cash dividends have been declared or paid to date.

    In February 2024, the Company completed an underwritten public offering in which the Company issued and sold 19,736,842 shares of its common stock at a public offering price of $8.74 per share. The Company received net

    16


     

    proceeds of approximately $161.8 million after deducting underwriting discounts, commissions and other offering expenses.

    ATM Agreement

    In November 2022, the Company entered into a sales agreement (the "2022 ATM Agreement") with Guggenheim Securities, LLC in connection with the establishment of an “at-the-market” offering program under which the Company could sell up to an aggregate of $50.0 million of shares of common stock (the “ATM Shares”) from time to time.

    In February 2024, in connection with the underwritten public offering described above, the Company terminated the 2022 ATM Agreement. No ATM Shares were ever sold pursuant to the 2022 ATM Agreement.

    In May 2024, the Company entered into a sales agreement (the "2024 ATM Agreement") with Guggenheim Securities, LLC in connection with the establishment of an “at-the-market” offering program under which the Company could sell up to an aggregate of $100 million of shares of common stock (the “ATM Shares”) from time to time. To date, no sales of common stock have been made under the 2024 ATM Agreement.

    2020 Equity Incentive Plan

    The Board adopted the 2020 Equity Incentive Plan (the "2020 Plan") on July 16, 2020 and the stockholders of the Company approved the 2020 Plan on September 29, 2020. The 2020 Plan replaced the predecessor plans (the "Prior Plans") that the Company assumed following its merger with Zafgen in May 2020. Options outstanding under the Prior Plans will remain outstanding, unchanged, and subject to the terms of the Prior Plans and the respective award agreements, and no further awards will be made under the Prior Plans. However, if any award previously granted under the Prior Plans, expires, terminates, is canceled, or is forfeited for any reason after the approval of the 2020 Plan, the shares subject to that award will be added to the 2020 Plan share pool so that they can be utilized for new grants under the 2020 Plan.

    The 2020 Plan provides for the grant of incentive stock options (“ISOs”), nonstatutory stock options (“NSOs”), stock appreciation rights, restricted stock awards, restricted stock unit awards, performance-based
    restricted stock units, and cash or other stock-based awards. ISOs may be granted only to the Company’s employees, including the Company’s officers, and the employees of the Company’s affiliates. All other awards may be granted to the Company’s employees, including the Company’s officers, the Company’s non-employee directors and consultants, and the employees and consultants of the Company’s affiliates.

    The maximum number of shares that may be issued in respect of any awards under the 2020 Plan is the sum of: (i) 1,700,000 shares plus (ii) an annual increase on January 1, 2021 and each anniversary of such date thereafter through January 1, 2030, equal to the lesser of (A) 4% of the shares issued and outstanding on the last day of the immediately preceding fiscal year, or (B) such smaller number of shares as determined by the Board (collectively, the “Plan Limit”). The maximum aggregate number of shares that may be issued under the 2020 Plan is 8,000,000 over the ten-year term of the 2020 Plan.

    As permitted by the 2020 Plan, the Company added 2,552,603 and 1,756,363 shares available for grant to the 2020 Plan on January 1, 2025 and January 1, 2024, respectively. As of March 31, 2025, 537,542 shares of common stock were available for grant under the 2020 Plan.

    During the twelve months ended December 31, 2024, options to purchase 1,242 shares issued under the Prior Plans were cancelled and became available for grant under the 2020 Plan. No such options were cancelled in the three months ended March 31, 2025.

    Restricted Stock Unit Grants

    During the three months ended March 31, 2025, the Company granted 344,988 shares of RSUs, which vest annually over four years to employees under the 2020 Plan. The RSUs have a weighted-average grant date fair value of $3.46 per unit.

    As of March 31, 2025, total unrecognized compensation expense for RSUs was $3.2 million, which is expected to be recognized over a weighted-average period of 2.76 years.

    Performance-Based Restricted Stock Unit Grants

    In January 2025, the Company granted performance-based RSUs (the "January 2025 PSU Awards") to each of the executive officers of the Company under the 2020 Plan. Each award was expressed as a target number of RSUs. With respect to the January 2025 PSU Awards, the Board established specified regulatory-related performance criteria and a corresponding performance period over which such performance criteria must be achieved, the satisfaction of which are conditions to earning the January 2025 PSU Awards and vesting of the underlying RSUs. As of March 31, 2025, January 2025 PSU Awards were outstanding covering 200,000 common stock underlying RSUs.

    The grant date fair value of the performance-based RSUs was $3.46 per unit based on the grant date closing price per share. As of March 31, 2025, the underlying performance criteria of the January 2025 PSU Awards were determined to be not probable of achievement, and no stock-based compensation expense was recognized for the three months ended March 31, 2025.

    Commitments and Contingencies

    Intellectual Property Licenses

    The Company is party to an exclusive License Agreement (the “WFUHS License”), dated November 30, 2016, as amended, with Wake Forest University Health Sciences (“WFUHS”) and an exclusive License Agreement (the “IU License”), dated November 30, 2016, as amended, with Indiana University (“IU”). Such agreements provide for a transferable, worldwide license to certain patent rights regarding technology used by the Company

    19


     

    with respect to the development of nomlabofusp. Both agreements continue from their effective date through the last to date of expiration of the licensed patents, unless earlier terminated by either party in accordance with their terms.

    In partial consideration for the right and license granted under these agreements, the Company will pay each of WFUHS and IU a royalty of a low single digit percentage of net sales of licensed products depending on whether there is a valid patent covering such products. As additional consideration for these agreements, the Company is obligated to pay each of WFUHS and IU certain milestone payments of up to $2.6 million in the aggregate upon the achievement of certain developmental milestones, which commenced with the enrollment of the first patient in a Phase 1 clinical trial. The Company enrolled the first patient in its SAD trial on December 11, 2019 and paid WFUHS and IU less than $0.1 million. The Company will also pay each of WFUHS and IU sublicensing fees ranging from a high-single digit to a low double-digit percentage of sublicense consideration depending on the Company’s achievement of certain regulatory milestones as of the time of receipt of the sublicense consideration. The Company is also obligated to reimburse WFUHS and IU for patent-related expenses. In the event that the Company disputes the validity of any of the licensed patents, the royalty rate would be tripled during such dispute. The Company is also obligated to pay to IU a minimum annual royalty of less than $0.1 million per annum.

    In the event that the Company is required to pay IU consideration, then the Company may deduct 20% of such IU consideration on a dollar-for-dollar basis from the consideration due to WFUHS. In the event that the Company is required to pay WFUHS consideration, then the Company may deduct 60% of such WFUHS consideration on a dollar-for-dollar basis from the consideration due to IU.

    In October 2022, the Company initiated dosing of a Phase 2 study. Pursuant to the terms of both the WFUHS License and the IU License, the company recognized milestone expense of $0.3 million within research and development expenses.

    Both agreements continue from their effective date through the last date of expiration of the licensed patents, unless earlier terminated by either party in accordance with their terms.

    Leases

    Bala Cynwyd Office Space

    On August 8, 2019, the Company entered into an operating lease for office space in Bala Cynwyd, Pennsylvania, effective as of December 15, 2019, for a period of three years and six months with an option to extend the lease for three additional years. Due to required tenant improvements to be completed by the landlord, the Company did not take immediate possession of the leased property and the lease term commenced on February 15, 2020.

    On March 9, 2023, the Company executed a lease extension agreement on its original 4,642 square footage of office space in Bala Cynwyd, Pennsylvania (which was set to expire in August 2023) and agreed to lease an additional 3,462 square feet of office space from the same landlord.

    The lease extension on the original 4,642 square footage commenced on September 1, 2023 and the Company recorded a right of use asset and lease liability of $0.5 million as of that date.

    The new lease on 3,462 additional square footage commenced on October 1, 2023 and the Company recorded a right of use asset and lease liability of $0.3 million as of that date.

    The right of use assets and lease liabilities with both of these leases are reflected in the financial statements for three months ended March 31, 2025 as are the right of use asset and lease liability of the Company's Boston office space discussed below.

    Boston Office Lease

    In connection with the Company's 2020 merger with Zafgen, on May 28, 2020, the Company acquired a non-cancellable operating lease for approximately 17,705 square feet of office space (the “Premises”). The lease expires on October 30, 2029. As part of the agreement, the Company was initially required to maintain a letter of credit, of $1.3 million. In October of 2024, upon the agreement with the landlord that we had achieved certain clinical development milestones required in the lease, this letter of credit was reduced to $0.6 million. During both periods presented, this cash deposit is classified as restricted cash within the condensed consolidated financial statements. In addition to the base rent, the Company is also responsible for its share of operating expenses, electricity and real estate taxes, which costs are not included in the determination of the leases’ right-of-use assets or lease liabilities.

    20


     

    The right-of-use asset is being amortized to other income/(expense) over the remaining lease term as a result of the sublease described below.

    On October 27, 2020, the Company entered into a sublease agreement (the “Sublease”) with Massachusetts Municipal Association, Inc. (the “Subtenant”), whereby the Company sublet the entire Premises to the Subtenant. The initial term of the Sublease commenced on December 4, 2020 and continues until October 30, 2029. In connection with the Sublease, the Company evaluated the need for impairment under ASC 360 "Impairment Testing: Long-Lived Assets Classified as Held and Used," and determined there was no impairment.

    The Sublease provided for an initial annual base rent of $0.8 million, which increases annually up to a maximum annual base rent of $1.0 million. The Subtenant also is responsible for paying to the Company future increases in operating costs (commencing on January 1, 2022), future increases in annual tax costs (commencing July 1, 2021) and all utility costs (commencing March 1, 2021) attributable to the Premises during the term of the Sublease. As part of the Sublease, the subtenant deposited a letter of credit in the amount of $0.8 million to assure their performance under the sublease. If there are no uncured events of default under the sublease, the amount of this security deposit decreases over time to $0.4 million on the sixth anniversary of the Sublease. The Company records sublease income on this sublease on a straight-line basis as a component of other income/(expense).

    Lab Space

    On November 5, 2018, the Company entered into an operating lease for office and lab space in Philadelphia, Pennsylvania, effective as of January 1, 2019, and expiring on December 31, 2020 with an option to extend the lease for two additional years. On August 4, 2020, the Company executed the first option to extend the lease for an additional year, expiring on December 31, 2021. On August 9, 2021, the Company executed the remaining option to extend the lease for an additional year, expiring on December 31, 2022. In September 2023, the Company extended this lease for an additional year with the option to terminate with four months' notice. On March 28, 2024, the Company gave the requisite notice and vacated the property in May 2024.

    On October 16, 2023, the Company entered into an operating lease for alternate lab space in King of Prussia, Pennsylvania for a period of four years. Due to required tenant improvements to be completed by the landlord, the Company did not take immediate possession of the leased property. The actual lease term commenced on May 10, 2024. Upon commencement of the lease term, the Company recorded a right of use asset and lease liability of $0.5 million which are reflected in these condensed consolidated financial statements.

    Lease Expense

    Expense arising from operating leases was $0.1 million during each of the three months ended March 31, 2025 and 2024. For operating leases, the weighted-average remaining lease term for leases at March 31, 2025 and December 31, 2024 was 4.2 and 4.5 years, respectively. For operating leases, the weighted average discount rate for leases at March 31, 2025 and December 31, 2024 was 11.0%. The Company has not entered into any financing leases.

    Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

    The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q (“Quarterly Report”), and the audited consolidated financial statements and notes thereto and management’s discussion and analysis of financial condition and results of operations for the year ended December 31, 2024 included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 24, 2025 (the "2024 Annual Report"). Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks, uncertainties, and assumptions. These statements are based on our beliefs and expectations about future outcomes and are subject to risks and uncertainties that could cause our actual results to differ materially from anticipated results. We undertake no obligation to publicly update these forward-looking statements, whether as a result of new information, future events or otherwise. You should read the “Risk Factors” section included in our 2024 Annual Report, in addition to the "Risk Factors" and “Cautionary Note Regarding Forward-Looking Statements” sections of this Quarterly Report for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

    Overview

    We are a clinical-stage biotechnology company focused on developing treatments for patients suffering from complex rare diseases using our novel cell penetrating peptide ("CPP") technology platform. Our lead product candidate, nomlabofusp (nomlabofusp is the International Nonproprietary Name and the United States Adopted Name for CTI-1601), is a subcutaneously administered, recombinant fusion protein intended to deliver tissue frataxin ("FXN"), an essential protein, to the mitochondria of patients with Friedreich's ataxia (“FA”). FA is a rare, progressive, and fatal disease in which patients are unable to produce sufficient FXN due to a genetic abnormality. Currently, there are no treatment options that address the core deficit of FA, low levels of FXN. Nomlabofusp represents the first potential therapy designed to systemically increase FXN levels in patients with FA.

    We believe that our CPP platform, which enables a therapeutic molecule to cross a cell membrane in order to reach intracellular targets, has the potential to enable the treatment of other rare and orphan diseases. We intend to use our proprietary platform to target additional orphan indications characterized by deficiencies in or alterations of intracellular content or activity.

    Since our inception, we have devoted substantially all of our resources to developing nomlabofusp, building our intellectual property portfolio, developing third-party manufacturing capabilities, business planning, raising capital, developing sales and marketing capacities, and providing general and administrative support for such operations.

    Nomlabofusp Program Update

    We have completed two Phase 1 clinical trials and a Phase 2 dose exploration trial, and have an ongoing Phase 2 OLE trial in patients with FA and an ongoing run-in study in adolescent patients with FA.

    In May 2021, we reported positive top-line data from our Phase 1 FA program after completing dosing of the single ascending dose ("SAD") trial in December 2020 and of the multiple ascending dose ("MAD") trial in March 2021. Data from these trials demonstrated proof-of-concept by showing that daily subcutaneous injections of nomlabofusp for up to 13 days resulted in dose-dependent increases in FXN levels from baseline compared to placebo in all evaluated tissues (buccal cells, skin, and platelets). There were no serious adverse events associated with either the MAD or SAD trials.

    In May 2023, we reported preliminary unblinded top-line data from the 25 mg cohort of the Phase 2 four-week, placebo-controlled, dose exploration trial of nomlabofusp in FA patients. Data from the cohort indicated nomlabofusp was generally well tolerated and showed increases in FXN levels from baseline compared to placebo in all evaluated tissues (skin and buccal cells) at day 14.

    In July 2023, the FDA cleared initiation of a second cohort (50 mg) of the four-week, placebo-controlled, Phase 2 dose exploration trial of nomlabofusp in patients with FA and the initiation of the OLE trial with daily dosing of 25 mg.

    In February 2024, we reported positive top-line data and successful completion of the Phase 2 dose exploration study. Nomlabofusp was generally well tolerated throughout the four-week treatment periods, had a predictable pharmacokinetic profile and led to dose dependent increases in FXN levels in all evaluated tissues (skin

    23


     

    and buccal cells) after daily dosing of 14 days followed by every other day dosing until day 28 in the 25 mg and 50 mg cohorts. Participants in the 25 mg (n=13) and 50 mg (n=15) cohorts were randomized 2:1 to receive subcutaneous injections of nomlabofusp or placebo. Patients who completed treatment in the Phase 2 dose exploration study or who previously completed a prior clinical trial of nomlabofusp are eligible to screen and possibly participate in the OLE study.

    In March 2024, we dosed the first patient in the OLE trial, evaluating daily subcutaneous injections of 25 mg of nomlabofusp self-administered or administered by a caregiver. The OLE study will evaluate the safety and tolerability, pharmacokinetics, and frataxin levels in peripheral tissues as well as other exploratory pharmacodynamic markers (lipid profiles and gene expression data) following long-term subcutaneous administration of nomlabofusp. In addition, following the completion of enrollment, as well as at least one participant completing one year of dosing, clinical assessments collected during the study will be compared to data from a matched control arm derived from participants in the Friedreich’s Ataxia Clinical Outcome Measures Study ("FACOMS") database.

    On May 30, 2024, we announced that the FDA's Center for Drug Evaluation and Research ("CDER") had selected nomlabofusp as one of a few programs for participation in the Support for Clinical Trials Advancing Rare Disease Therapeutics ("START") Pilot Program. The objective of the program is to accelerate the development of drugs for rare diseases that lead to significant disability or death by facilitating frequent advice and regular communication with the FDA staff to expedite the review process of biologics and drugs.

    In September 2024, we received access to the Medicines and Healthcare Regulatory Agency ("MHRA”) Innovative Licensing and Access Pathway (“ILAP”) for the treatment of adults and children with FA. The ILAP is facilitating patient access to novel treatments by accelerating time to market through opportunities for enhanced engagements with UK regulatory authorities and other stakeholders. Along with the receipt of the ILAP designation, nomlabofusp has already been granted orphan drug designations in the U.S. and the European Union (the “EU”), and access to the PRIME scheme in the EU.

    In December 2024, we reported positive initial data from the ongoing OLE study. This data included safety, FXN levels, clinical, pharmacokinetic data and dose escalation:

    •
    Nomlabofusp was generally well tolerated for up to 260 days in subjects. The most common adverse events were injection site reactions, with most being mild, brief in duration, and self-limited. Two participants had serious adverse events (one seizure and one anaphylactic reaction) that resolved within 24 hours and withdrew from the study;
    •
    Long-term 25 mg tissue FXN levels showed positive mean change from baseline of 1.32 pg/μg in buccal cells and 9.28 pg/μg in skin cells at Day 90 and that 25 mg of nomlabofusp increased and maintained tissue FXN levels over time, increasing from a mean level of 15% of HV at baseline to 30% in buccal cells and from 16% to 72% in skin cells at Day 90;
    •
    Tissue FXN levels appear to reach steady-state levels by Day 30 in buccal cells;
    •
    Early clinical data showed trends toward improvement across a number of clinical outcomes for long-term 25 mg daily nomlabofusp including: (1) decreased values indicating early trends towards improvement in the Modified Friedreich's Ataxia Rating Scale (mFARS) and the FARS-Activities of Daily Living ("ADL"), Modified Fatigue Impact Scale and 9 hole peg test at 90 days relative to baseline;
    •
    Key pharmacokinetic data showed rapid absorption after subcutaneous administration with exposure appearing to reach steady state in plasma by day 30 with no further accumulation, which is consistent with data from our Phase 1 and Phase 2 studies.

    Also in December 2024, we announced that we were increasing the dose in the OLE to 50 mg of nomlabofusp daily for then currently enrolled and all future OLE study participants. In March 2025, we announced that our Safety Monitoring Team has deemed anaphylaxis as an adverse drug reaction likely associated with nomlabofusp and therefore, we expect to see additional reactions. To reduce the risk of allergic reactions, including anaphylaxis, we amended the OLE protocol to administer premedication for the first month of dosing. The OLE study is ongoing with seven sites activated and participants continuing to enroll. Active study participants are currently receiving the 50 mg dose of nomlabofusp. We plan to provide an update on OLE data on at least 30 to 40 study participants, some of whom have been receiving nomlabofusp for more than a year, in September 2025.

    In January 2025, we initiated dosing of adolescents (12-17 years old) in a PK run-in study for pediatric patients with FA. Study participants in the PK run-in study were randomized 2:1 to receive either nomlabofusp at a weight-base dose expected to match the PK of adults receiving the 50 mg dose, or placebo, daily for seven days. Dosing of this adolescent PK run-in study was completed in March 2025. Following assessment of safety and PK

    24


     

    data, participants will be eligible to screen for the OLE study. The data from this cohort is expected to be presented in the nomlabofusp program update in September 2025.

    In February 2025, FDA accepted the data supporting the comparability of the lyophilized drug product to the frozen solution and agreed with our plans to introduce the lyophilized product into our clinical development program in mid-2025. The frozen solution is the dosage form currently being used in the OLE. The lyophilized drug product is the formulation that we intend to commercialize.

    In March 2025, we announced that FDA stated as part of a START pilot program that it is open to considering the use of FXN concentration as a reasonably likely surrogate endpoint (“RLSE”) and the acceptability of FXN concentration as an RLSE to support will be a matter of review in a future marketing application. FDA recommended focusing on assessments of skin FXN concentrations rather than buccal FXN concentrations due to more consistent sampling and less variability. FDA acknowledged that data we recently submitted appear to support a relationship between increased FXN concentrations in skin cells and relevant tissues such as the heart, dorsal root ganglion and skeletal muscle. FDA also acknowledged that the nonclinical studies we submitted were performed at relevant human doses. FDA also suggested that we consider exploring the relationship between increases in FXN in skin and changes in pharmacodynamic (PD) markers such as lipid profiles and/or clinical measures to provide additional support for the use of FXN as an RLSE. We continue to interact with the FDA under the START pilot program, including seeking on the adequacy of the safety data set for a BLA submission seeking accelerated approval targeted for the end of 2025.

    Additionally, we have obtained feedback from both FDA and EMA on the global Phase 3 study protocol and we are on track to initiate the study by mid-2025 with potential sites in the U.S., E.U., U.K, Canada, and Australia.

    Financing Activities, including Recent Material Financings

    We have funded our operations to date primarily with proceeds from sales of common stock, proceeds from the sale of prefunded warrants for the purchase of common stock, the acquisition in 2020 of cash, cash equivalents, marketable securities and restricted cash upon the merger with Zafgen, Inc. ("Zafgen") and, prior to the 2020 merger with Zafgen, capital contributions from Chondrial Holdings, LLC.

    In February 2024, we completed an underwritten public offering in which we issued and sold 19,736,842 shares of our common stock at a public offering price of $8.74 per share. We received net proceeds of approximately $161.8 million after deducting underwriting discounts, commissions and other offering expenses.

    In May 2024, we entered into a Sales Agreement (the "2024 ATM Agreement") with Guggenheim Securities, LLC in connection with the establishment of an “at-the-market” offering program providing for the sale of up to an aggregate of $100 million of shares of our common stock from time to time. To date, we have made no sales under the 2024 ATM agreement.

    Critical Accounting Policies and Significant Judgments and Estimates

    Our condensed, consolidated financial statements are prepared in accordance with Generally Accepted Accounting Principles ("GAAP"). The preparation of our consolidated financial statements and related disclosures requires us to make estimates and assumptions that affect the reported amount of assets, liabilities, costs and expenses, and related disclosures. We believe that the estimates and assumptions involved in the accounting policies described below may have the greatest potential impact on our consolidated financial statements and, therefore, consider these to be our critical accounting policies. We evaluate these estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions and conditions.

    Research and Development Expense

    Costs for certain research and development activities, such as manufacturing, non-clinical studies and clinical trials are generally recognized based on the evaluation of the progress of completion of specific tasks using information and data provided by our vendors and collaborators, and accordingly, are considered an area of significant judgment and management’s review of manufacturing, non-clinical and clinical expenses. This process involves reviewing open contracts and purchase orders, communicating with our personnel and outside vendors to identify services that have been performed on our behalf and estimating the level of service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. We work with vendors and suppliers to ensure that our estimates of our research and development expenses are reasonable. We expect to increase our investment in research and development in order to advance nomlabofusp through additional clinical trials. As a result, we expect that our research and development expenses will continue to

    25


     

    increase in the foreseeable future as we pursue clinical development of nomlabofusp and/or any other product candidates we develop.

    Stock Compensation Expense

    We measure all stock-based awards granted to employees and directors based on the fair value on the date of grant using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires the use of highly subjective assumptions which determine the fair value of stock-based awards. The assumptions used in our option-pricing model represent management’s best estimates. These estimates are complex, involve a number of variables, uncertainties and assumptions and the application of management’s judgment, and thus are inherently subjective. If factors change and different assumptions are used, our stock-based compensation expense could be materially different in the future.

    Prior to May 28, 2020, we were a private company and lacked company-specific historical and implied volatility information for our common stock. Prior to January 1, 2023, the Company estimated its expected common stock price volatility solely based on the historical volatility of publicly traded peer companies with comparable characteristics including enterprise value, risk profiles and position within the industry. Beginning on January 1, 2023, the Company began blending its historical data starting in June 2020 (following its merger with Zafgen in 2020) with its historical peer group. We regularly evaluate our peer group to assess changes in circumstances where identified companies may no longer be similar to us, in which case, more suitable companies whose share prices are publicly available would be utilized in the calculation. We expect to continue to do so until we have full historical data regarding the volatility of our own traded stock price.

    The expected term of our stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield considers the fact that we have never paid cash dividends on common stock and do not expect to pay any cash dividends in the foreseeable future.

    Compensation expense of those awards is recognized over the requisite service period, which is generally the vesting period of the respective award. Typically, we issue awards with only service-based vesting conditions and record the expense for these awards using the straight-line method. We account for forfeitures as they occur.

    In January, 2025, our Board of Directors ("Board") approved the issuance of an aggregate of 200,000 performance-based restricted stock units ("RSUs") to certain of our executive officers (the "January 2025 PSU Awards"). The Board established specified performance criteria and a corresponding performance period over which such performance criteria must be achieved, the satisfaction of which are conditions to earning the January 2025 Awards and vesting of the underlying RSUs. As of March 31, 2025, the underlying performance criteria of the January 2025 PSU Awards were determined to be not probable of achievement, and no stock-based compensation expense was recognized for the three months ended March 31, 2025.

    We classify stock-based compensation expense in our consolidated statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

    Financial Operations Overview

    Revenue

    To date, we have not generated any revenue from product sales, and do not expect to generate any revenue from the sale of products in the foreseeable future. If our development efforts result in clinical success and regulatory approval or collaboration agreements with third parties for our product candidates, we may generate revenue from those product candidates or collaborations.

    Operating Expenses

    The majority of our operating expenses since inception have consisted primarily of research and development activities, and general and administrative costs.

    26


     

    Research and Development Expenses

    Research and development expenses, which consist primarily of costs associated with our product research and development efforts, are expensed as incurred. Research and development expenses consist primarily of:

    •
    third-party contract costs relating to research, formulation, manufacturing, non-clinical studies and clinical trial activities;
    •
    employee related costs, including salaries, benefits and stock-based compensation expenses for employees engaged in scientific research and development functions;
    •
    external costs of outside consultants and vendors;
    •
    payments made under our third-party licensing agreements;
    •
    sponsored research agreements;
    •
    laboratory consumables; and
    •
    allocated facility-related costs.

    At this time, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the clinical and commercial development of nomlabofusp, or any other product candidates we develop. We are also unable to predict when, if ever, material net cash inflows will commence from sales of our product candidates. The duration, costs, and timing of clinical trials and development of nomlabofusp or any other product candidates we develop will depend on a variety of factors, including:

    •
    the scope, rate of progress and expense of clinical trials and other research and development activities;
    •
    clinical trial results;
    •
    uncertainties in clinical trial enrollment rate or design;
    •
    significant and changing government regulation;
    •
    the timing and receipt of any regulatory approvals;
    •
    the influence of the FDA or other regulatory authorities on our clinical trial design and timing;
    •
    establishing manufacturing capabilities or making arrangements with third-party manufacturers and risk involved with development of manufacturing processes, FDA pre-approval inspection practices and successful completion of manufacturing batches for clinical development and other regulatory purposes;
    •
    our ability to obtain and maintain patent and trade secret protection and regulatory exclusivity for our product candidates; and
    •
    our ability to recruit and retain key research and development personnel.

    A change in the outcome of one or more of these variables with respect to the development of a product candidate could significantly change the costs, timing and viability associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to require us to conduct additional non-clinical or clinical trials beyond those that we currently anticipate will be required for the completion of clinical development of a product candidate, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development.

    General and Administrative Expenses

    General and administrative expenses consist primarily of personnel costs, consisting of salaries, related benefits and stock-based compensation, costs related to our executive, finance, information technology, and costs related to other administrative functions. General and administrative expenses also include insurance expenses and professional fees for auditing, tax, and legal services, including legal expenses to pursue patent protection for our intellectual property. We expect that our general and administrative expenses will increase in the foreseeable future as we hire additional employees to implement, improve and scale our operational, financial, commercial and management systems.

    Research and development expenses

    Research and development expenses for the three months ended March 31, 2025 increased $13.6 million compared to the three months ended March 31, 2024. The increase was primarily driven by an increase of $7.1 million in nomlabofusp manufacturing costs, an increase of $2.8 million in clinical costs primarily associated with the ongoing pediatric study which started and completed patient enrollment in the quarter ended March 31, 2025 and the start of our planned global Phase 3 study in the first quarter of 2025, an increase of $1.6 million in personnel expense due to increased headcount, and an increase of $1.2 million in consulting fees.

    General and administrative expenses

    General and administrative expenses for the three months ended March 31, 2025 increased $0.8 million compared to the three months ended March 31, 2024. The increase in general and administrative expenses was primarily driven by an increase of $0.7 million in personnel expense, an increase of $0.5 million in consulting fees primarily associated with commercial activities, partially offset by a decrease of $0.3 million in stock compensation expense.

    Other income (expense), net

    Other income (expense), net was $1.9 million income in the three months ended March 31, 2025 compared to $2.1 million income in the three months ended March 31, 2024. Other income consists primarily of interest income.

     

    Liquidity and Capital Resources

    Since our inception, we have not generated any revenue from any sources, including from product sales, and have incurred significant operating losses and negative cash flows from our operations. We have devoted substantially all of our resources to developing nomlabofusp, building our intellectual property portfolio, developing third-party manufacturing capabilities, business planning, capital raising, and providing general and administrative support for such operations.

    Net cash used in operating activities

    During the three months ended March 31, 2025, operating activities used $26.5 million of cash, resulting from our net loss of $29.3 million, adjusted for noncash expenses of $1.1 million and changes in our operating assets and liabilities resulting in a source of cash of $1.6 million. Our net loss was primarily attributed to research and development activities related to our nomlabofusp program and our general and administrative expenses as described above. Noncash expenses are primarily stock-based compensation expenses. The change in operating assets and liabilities was primarily due to an increase in accounts payable and decrease in both prepaid expense and accrued expenses.

    During the three months ended March 31, 2024, operating activities used $10.4 million of cash, resulting from our net loss of $14.7 million, adjusted for noncash expenses of $1.6 million and changes in our operating assets and liabilities resulting in a source of cash of $2.7 million. Our net loss was primarily attributed to research and development activities related to our nomlabofusp program and our general and administrative expenses as described above. Noncash expenses are primarily stock-based compensation expenses. The change in operating assets and liabilities was primarily due to an increase in accounts payable and accrued expenses.

    Net cash provided by (used in) investing activities

    During the three months ended March 31, 2025, investing activities provided $14.4 million primarily from $67.0 million of cash provided by maturities of marketable securities, partially offset by the purchase of $52.3 million in marketable securities.

    During the three months ended March 31, 2024, investing activities used $68.4 million of cash to purchase $84.9 million of marketable securities, partially offset by $16.5 million of cash provided by maturities of marketable securities.

    Net cash provided by financing activities

    During the three months ended March 31, 2025, there were no financing activities.

    During the three months ended March 31, 2024, financing activities provided approximately $162.2 million of cash flows primarily from an offering of common stock.

    Operating Capital Requirements

    We have not yet commercialized any products and do not expect to generate revenue from the commercial sale of any products for several years, if at all.

    We have to date incurred net losses. We incurred net losses of approximately $29.3 million and $14.7 million for the three months ended March 31, 2025 and 2024, respectively. As of March 31, 2025, we had an accumulated deficit of $298.4 million and cash, cash equivalents and marketable securities of $157.5 million, excluding restricted cash of $0.6 million.

    Losses have resulted principally from costs incurred in connection with research and development activities, and general and administrative costs associated with the development of nomlabofusp and our operations. We expect to incur significant expenses and operating losses for the foreseeable future as we expect to continue to incur expenses in connection with our ongoing activities, if and as we:

    •
    continue to advance the development of nomlabofusp through additional clinical trials, including related manufacturing costs;
    •
    seek to identify and advance development of additional product candidates into clinical development and identify additional indications for our product candidates;
    •
    seek to obtain regulatory approvals for nomlabofusp and other potential product candidates;
    •
    identify, acquire or in-license other product candidates and technologies;
    •
    maintain, leverage and expand our intellectual property portfolio; and
    •
    expand our operational, financial, commercial and management systems and personnel, including personnel to support our clinical development and future commercialization efforts and our operations as a public company.

    29


     

    We anticipate that our current cash, cash equivalents and marketable securities will fund operations into the second quarter of 2026. If we encounter unexpected delays in our clinical trials or if there are other unanticipated changes to our operating plan from our current assumptions that negatively impact our operations, we may reduce expenditures in order to further extend our existing cash resources. Until we can generate substantial revenue, if ever, we expect to seek additional funding through a combination of public or private equity offerings, debt/royalty financings, collaborations, strategic alliances and licensing arrangements or other sources. The incurrence of indebtedness would result in increased fixed payment obligations and we may be required to agree to certain restrictive covenants, such as limitations on our ability to incur additional debt, minimum cash balances, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates.

    There can be no assurance that we will be able to raise sufficient additional capital on acceptable terms, if at all. If such additional financing is not available on satisfactory terms, or is not available in sufficient amounts, or we do not have sufficient authorized shares, we may be required to delay, limit, or eliminate the development of business opportunities and our ability to achieve our business objectives, our competitiveness, and our business, financial condition, and results of operations will be materially adversely affected. We could also be required to seek funds through arrangements with collaborative partners, strategic alliances or otherwise at an earlier stage than otherwise would be desirable and we may be required to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us, any of which may have a material adverse effect on our business, operating results and prospects. In addition, geopolitical tensions including regional conflicts around the world, adverse macroeconomic events, including those due to inflationary pressures, rising interest rates, banking instability, monetary policy changes, changes in trade policies, including tariffs (including tariffs and trade protection measures that have been or may in the future be imposed by the U.S. or other countries), economic slowdowns or recessions, health epidemics, unforeseen emergencies and other outbreaks of communicable diseases could disrupt our operations, the operations of third parties on which we rely or the operations of regulatory agencies we interact with in the development of nomlabofusp and any other product candidates that we may develop which may reduce our ability to access capital, which could negatively affect our liquidity and ability to continue as a going concern.

    If we are unable to obtain sufficient funding when needed and/or on acceptable terms, we may be required to significantly curtail, delay or discontinue one or more of our research and development programs, the manufacture of clinical and commercial supplies, product portfolio expansion and/or pre commercialization efforts, which could adversely affect our business prospects, or we may be unable to continue operations. Certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates.

    Off-Balance Sheet Arrangements

    During the periods presented we did not have, and we currently do not have, any off-balance sheet arrangements, as defined under applicable SEC rules, such as relationships with unconsolidated entities or financial partnerships, which are often referred to as structured finance or special purpose entities, established for the purpose of facilitating financing transactions that are not required to be reflected on our balance sheets.

    Item 3. Quantitative and Qualitative Disclosures about Market Risk

    We are a "smaller reporting company" as defined by Rule 12b-2 of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and are not required to provide the information under this item.

    Item 4. Controls and Procedures

    We maintain “disclosure controls and procedures,” as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, to allow timely decisions regarding required disclosure.

    The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

    With respect to the quarter ended March 31, 2025, under the supervision and with the participation of our management, we conducted an evaluation of the effectiveness of the design and operations of our disclosure controls and procedures. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective.

    Management does not expect that our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control systems are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in a cost-effective control system, no evaluation of internal control over financial reporting can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been or will be detected.

    Changes in Internal Control Over Financial Reporting

    There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the fiscal quarter ended March 31, 2025 which have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
