Amylyx Pharmaceuticals Stock Soars After the Close: Here’s Why

Amylyx Pharmaceuticals Inc (NASDAQ:AMLX) shares are trading higher in Monday’s after-hours session after the company scheduled a Phase 3 trial results readout for this week.

Amylyx Pharma Announces Phase 3 LUCIDITY Results Date

Amylyx Pharmaceuticals said it will announce the top-line results for its Phase 3 LUCIDITY clinical trial of avexitide in post-bariatric hypoglycemia (PBH) Tuesday morning. Senior management will hold a conference call at 8 a.m. ET to discuss results from the trial.

Avexitide is an investigational, first-in-class glucagon-like peptide-1 (GLP-1) receptor antagonist with FDA Breakthrough Therapy Designation in PBH.

The trial enrolled 78 participants over 16 weeks as a multicenter, randomized, double-blind, placebo-controlled trial evaluating the efficacy and safety of avexitide in adults with PBH following Roux-en-Y gastric bypass (RYGB) surgery.

The last participant was randomized and dosed in the Phase 3 clinical trial in March. If approved, commercial launch of avexitide is anticipated in 2027.
