The company is advancing a pipeline including avexitide (for post-bariatric hypoglycemia), AMX0035 (for Wolfram syndrome and PSP), and AMX0114 (for ALS).

Material Changes vs. Prior Period
- Revenue Elimination: Product revenue dropped to zero in Q1 2025 compared to $88.6 million in Q1 2024, reflecting the complete cessation of sales for RELYVRIO/ALBRIOZA.
- Expense Reduction: Total operating expenses decreased by 82% to $37.8 million. This was driven by a 73% reduction in SG&A expenses (due to a 70% workforce reduction in April 2024) and a 40% reduction in R&D expenses (primarily due to winding down ALS programs for AMX0035).
- Capital Raise: In January 2025, the company completed an underwritten public offering of 19.7 million shares at $3.50 per share, raising approximately $65.5 million in net proceeds.
- Investment Activity: The company increased its marketable securities portfolio from $99.1 million to $144.3 million during the quarter.
Guidance, Outlook, and Risks
- Clinical Pipeline Progress:
- Avexitide: Recruiting for the pivotal Phase 3 LUCIDITY trial in post-bariatric hypoglycemia (PBH) began in February 2025; the first participant was dosed in April 2025. Topline data is expected in H1 2026.
- AMX0035: Enrollment for the Phase 2b/3 ORION trial in PSP was completed in January 2025. Unblinded analysis data is expected in Q3 2025 to inform a go/no-go decision for Phase 3. Positive Phase 2 data in Wolfram syndrome was announced in October 2024.
- AMX0114: The Phase 1 LUMINA trial for ALS began recruiting in February 2025, with the first participant dosed in April 2025.
- Liquidity Outlook: Management believes existing cash, cash equivalents, and marketable securities ($204.1 million as of March 31, 2025) are sufficient to fund operations through 2026.
- Legal Proceedings: The company is defending against a putative class action lawsuit (Shih v. Amylyx) and a derivative complaint regarding the commercial results of RELYVRIO. The derivative action is currently stayed pending the outcome of the class action motion to dismiss.
- Risks: Key risks include the failure of ongoing clinical trials, inability to secure additional funding if needed, regulatory delays, and the high cost of operating as a public company following the loss of "emerging growth company" status.
Investor Verification Checklist
- Verify the enrollment status and timeline for the LUCIDITY (avexitide) and ORION (AMX0035) trials, as these are critical value drivers.
- Monitor the status of the Shih v. Amylyx securities litigation and any potential settlement impacts.
- Track the company's cash burn rate against the stated runway through 2026 to assess the need for future dilutive financing.
- Review the specific allocation of R&D spend between the three main programs (avexitide, AMX0035, AMX0114) in future filings.
- Confirm the status of manufacturing agreements with third-party CMOs following the restructuring and product withdrawal.
