What believers are saying

  • Post-bariatric hypoglycemia has no FDA-approved therapies, creating a clear unmet-need launch opportunity.
  • Amylyx ended Q1 2026 with $279.8 million cash, funding operations into 2028.
  • TCG Crossover's 5.7% stake signals specialist investor confidence in the endocrine pipeline.

What critics are saying

  • PHOENIX failed in ALS, leaving AMX0035 without a validated commercial franchise.
  • LUCIDITY topline data in Q3 2026 is binary; a miss delays first revenue.
  • Expanded access exposure before approval can surface adverse events and weaken avexitide's regulatory story.

What makes Amylyx Pharmaceuticals unique

  • Amylyx now centers on avexitide, a first-in-class GLP-1 antagonist for post-bariatric hypoglycemia.
  • LUCIDITY fully enrolled in May 2026, with topline results expected in Q3 2026.
  • The U.S. Expanded Access Programme, launched May 5, 2026, broadens physician and patient exposure.

Amylyx completes enrollment in Phase 3 trial of first-in-class therapy for post-bariatric hypoglycemia

Amylyx Pharmaceuticals has completed enrolment in LUCIDITY, its pivotal Phase 3 trial of avexitide for post-bariatric hypoglycaemia following Roux-en-Y gastric bypass surgery. The 16-week, double-blind, placebo-controlled study has randomised and dosed its final participant. The milestone positions Amylyx to potentially file for approval of a first-in-class GLP-1 receptor antagonist for a condition with no FDA-approved therapies. Topline results are expected in Q3 2026. Earlier trials showed consistent reductions in severe hypoglycaemic events. The company maintains a $317 million cash balance to support trial milestones but remains loss-making. Analyst forecasts project revenues of $107.8 million and earnings of $23.1 million by 2029, though estimates vary considerably.
