Amylyx Pharmaceuticals Inc. has decided to discontinue the ORION program for AMX0035 in progressive supranuclear palsy (PSP) after Phase 2b trial results showed no significant differences from placebo. The drug was well-tolerated, and the company will now focus on the Phase 3 LUCIDITY trial of avexitide, with enrollment expected to conclude in 2025. Additionally, Amylyx is advancing AMX0035 in Wolfram syndrome and AMX0114 in ALS, with early Phase 1 LUMINA trial data expected in 2025.
