Amylyx Pharmaceuticals Inc. has announced its decision to discontinue the ORION program of AMX0035 for adults with progressive supranuclear palsy (PSP).

Despite these results, AMX0035 was generally well-tolerated, with safety data consistent with previous studies. Moving forward, Amylyx will focus on advancing the Phase 3 LUCIDITY trial of avexitide, with enrollment expected to conclude in 2025 and topline data anticipated in the first half of 2026.
