Revenue for the year ended December 31, 2025 $16.1 million compared to $27.1 million in 2024, a decrease of $11 million primarily driven by a $10.7 million decrease in collaboration revenue and a $6.1 million decrease in contract manufacturing revenues, offset by a $5.8 million increase in license revenues.
Cost of contract manufacturing revenues Nil for the year ended December 31, 2025, compared to $17.1 million in 2024, following the divestment of the Lexington facility in 2024.
Research and development expenses $140.7 million for the year ended December 31, 2025, compared to $143.8 million in 2024, a decrease of $3.1 million primarily driven by a $26 million decrease in total other research and development expenses, offset by a $22.9 million increase in total direct research and development expenses.
Selling, general and administrative expenses $65.5 million for the year ended December 31, 2025, compared to $52.7 million in 2024, an increase of $12.8 million primarily driven by a $9.4 million increase in professional fees, a $3.6 million increase in employee and contractor-related expenses, and a $2.8 million increase in other expenses.
Cash, cash equivalents and investment securities $622.5 million as of December 31, 2025, compared with $367.5 million as of December 31, 2024, a net increase primarily attributable to proceeds of approximately $404.2 million raised through public offerings of ordinary shares and prefunded loans.
AMT-130: A novel one-time administered treatment for Huntington's disease. Demonstrated statistically significant slowing of disease progression in Phase I/II study. However, the FDA recommended a Phase III randomized double-blind sham surgery-controlled study for further evidence. Regulatory discussions are ongoing, with plans for a 4-year analysis in Q3 2026.
AMT-191: Gene therapy for Fabry disease. Preliminary data showed elevated alpha-Gal A enzyme activity and successful withdrawal from enzyme replacement therapy for all 11 patients. Dosing paused at mid and high doses due to dose-limiting toxicity in two patients.
AMT-260: Gene therapy for mesial temporal lobe epilepsy. Initial data showed reduction in seizure frequency with no serious adverse events. Enrollment in the second cohort is ongoing, with updates expected in Q2 2026.
Huntington's Disease (HD) Market: Expanded engagement with U.S. and ex-U.S. regulators and healthcare providers. Actively pursuing named patient and early access programs outside the U.S. to expedite access to AMT-130.
Fabry Disease Market: Positioning AMT-191 as a one-time gene therapy to compete with chronic enzyme replacement therapies.
Temporal Lobe Epilepsy Market: Targeting patients with drug-resistant epilepsy through AMT-260, addressing unmet needs in seizure reduction and quality of life.
Financial Position: Cash, cash equivalents, and investment securities totaled $622.5 million as of December 31, 2025, ensuring funding into the second half of 2026.
R&D Expenses: Decreased by $3.1 million year-over-year, primarily due to reduced costs from the 2024 divestiture of the Lexington manufacturing operation.
Selling, General, and Administrative Expenses: Increased by $12.8 million year-over-year, driven by preparation for AMT-130 commercialization and professional fees.
Regulatory Strategy: Focused on engaging with U.S. and ex-U.S. regulatory authorities to define pathways for AMT-130 approval, leveraging natural history data to address FDA feedback.
Pipeline Development: Advancing AMT-130, AMT-191, and AMT-260 with plans for further data generation and regulatory discussions in 2026.
Regulatory Hurdles: The FDA has strongly recommended a Phase III randomized double-blind sham surgery-controlled study for AMT-130, which could delay the approval process. The company disagrees with the FDA's interpretation of the Phase I/II data, creating uncertainty around the regulatory pathway.
Clinical Trial Challenges: The FDA highlighted the absence of treatment effects relative to sham subjects in the U.S. Phase I/II study after 12 months, raising concerns about the efficacy of AMT-130 in the short term. Additionally, the company faces challenges in designing a feasible and ethical Phase III trial.
Patient Recruitment and Retention: A multiyear sham-controlled study could impose significant risks and burdens on patients, potentially affecting recruitment and retention rates. The HD patient community has expressed concerns about the ethical implications of such a trial design.
Financial Risks: Revenue decreased from $27.1 million in 2024 to $16.1 million in 2025, driven by declines in collaboration and contract manufacturing revenues. Increased expenses for commercialization preparation and professional fees have also impacted financials.
Safety Concerns: In the Fabry disease program, two patients experienced dose-limiting toxicities, leading to a pause in dosing at mid and high doses. Additionally, a serious adverse event related to AMT-162 in the ALS program has resulted in a voluntary enrollment and treatment hold.
Market Access and Competition: The company faces challenges in securing regulatory approvals and market access for AMT-130 and other pipeline products, especially in competitive markets like Fabry disease and epilepsy.
AMT-130 for Huntington's Disease: The company is focused on engaging with the FDA to define a clear regulatory path forward for AMT-130. They are evaluating the FDA's recommendation for a Phase III randomized double-blind sham surgery-controlled study while also considering alternative approaches leveraging natural history data. A Type B meeting is planned for Q2 2026 to discuss Phase III study designs. Additionally, a 4-year analysis of Phase I/II data is expected in Q3 2026 to further assess the therapy's durability and magnitude of effect. Ex-U.S. regulatory discussions are ongoing, with potential opportunities for expedited approval in certain markets.
AMT-191 for Fabry Disease: The company reported durable dose-dependent elevation in alpha-Gal A enzyme activity across three dose levels, with all 11 patients successfully withdrawn from enzyme replacement therapy. However, dosing at mid and high doses is paused due to observed dose-limiting toxicities. The company is evaluating the safety profile and plans to continue advancing the program.
AMT-260 for Mesial Temporal Lobe Epilepsy: Enrollment in the second cohort is expected to be completed by mid-2026. An update on the first cohort's safety, tolerability, and seizure frequency outcomes is planned for Q2 2026. The company sees significant market opportunity for this gene therapy in addressing drug-resistant epilepsy.
AMT-162 for SOD1-ALS: The program remains on voluntary enrollment and treatment hold due to observed dose-limiting toxicity. Data collection and evaluation are ongoing.
