Its current pipeline includes avexitide (for post-bariatric hypoglycemia and congenital hyperinsulinism), AMX0035 (for Wolfram syndrome and progressive supranuclear palsy), and AMX0114 (for amyotrophic lateral sclerosis).

Material Changes vs. Prior Period
- Revenue Collapse: Net product revenue decreased 77% to $87.4 million, driven by the voluntary discontinuation of RELYVRIO/ALBRIOZA in April 2024 following the failure of the Phase 3 PHOENIX trial to meet its primary and secondary endpoints.
- Significant One-Time Charges:
- Inventory Impairment: Recorded a $118.7 million charge for inventory write-downs and losses on firm purchase commitments related to the discontinued product.
- Acquired IPR&D: Recorded a $36.2 million expense for the acquisition of avexitide assets from Eiger Pharmaceuticals in July 2024.
- Restructuring: Incurred $22.9 million in restructuring expenses, primarily for severance, following a workforce reduction of approximately 70% in April 2024.
- Profitability Shift: The company swung from a net income of $49.3 million in 2023 to a net loss of $301.7 million in 2024.
- Operating Expenses: While R&D and SG&A expenses decreased due to the restructuring and cessation of commercial activities, total operating expenses increased by 18% due to the significant non-cash and one-time charges listed above.
Guidance, Outlook, and Risks
Outlook and Liquidity:
- As of December 31, 2024, the company held $176.5 million in cash and marketable securities.
- In January 2025, the company completed a follow-on offering raising approximately $65.5 million in net proceeds.
- Management believes current resources, combined with the January 2025 proceeds, are sufficient to fund operations through 2026.
Clinical Pipeline Status:
- Avexitide: Recruiting for the pivotal Phase 3 LUCIDITY trial in post-bariatric hypoglycemia (PBH) began in February 2025. Topline data is anticipated in the first half of 2026.
- AMX0035: Positive topline data was announced in October 2024 for the Phase 2 HELIOS trial in Wolfram syndrome. The Phase 2b/3 ORION trial for progressive supranuclear palsy (PSP) is ongoing, with interim data expected in Q3 2025.
- AMX0114: Recruiting for the Phase 1 LUMINA trial in ALS began in February 2025.
Key Risks and Contingencies:
- Capital Requirements: The company expects to incur significant losses for the foreseeable future and will require additional funding to advance its pipeline. Failure to secure financing could force delays or elimination of development programs.
- Regulatory and Clinical Risk: Success depends heavily on the outcomes of late-stage trials for avexitide and AMX0035. The company has limited experience in the endocrine field (avexitide) and faces high failure rates common in neurodegenerative drug development.
- Legal Proceedings: The company is subject to a putative securities class action lawsuit (Shih v. Amylyx) and a derivative complaint alleging false statements regarding RELYVRIO commercial results. The company intends to defend these vigorously.
- Manufacturing Dependence: The company relies entirely on third-party contract manufacturers for clinical and potential commercial supply.
Investor Verification Checklist
- Cash Runway: Verify the sufficiency of the $176.5 million year-end cash balance plus the $65.5 million January 2025 proceeds to fund operations through 2026, considering potential inflation or trial delays.
- Avexitide Trial Progress: Monitor enrollment rates and safety data for the Phase 3 LUCIDITY trial, which is the company's most advanced asset.
- Legal Exposure: Track the status of the Shih class action lawsuit and the derivative complaint for potential financial impact or management distraction.
- AMX0035 Data Readouts: Confirm the timing and results of the interim analysis for the ORION trial (PSP) and the Week 48 data for the HELIOS trial (Wolfram syndrome).
- Patent Portfolio: Review the expiration dates of the acquired avexitide patents (some expiring as early as 2026) and the status of the European patent opposition regarding AMX0035 components.
