Alzheimer's Disease: registrational readout pending

Entered Phase 3 on partial signal mid-stage evidence. The registry's posted readout date (2026-05) has passed without a status update. Check News for topline announcements.

NCT03625622: The study was randomized, quadruple-masked, and placebo-controlled, with 210 participants, and used clinical cognitive and global-change measures (ADAS-Cog 13 and ADCS-CGIC) as primary endpoints. Registry results were not posted at the time of grading; the key result shown was recovered from the cited external source.

The overall-population primary endpoint showed no significant differences (published qualitatively); the numeric improvement shown is a post-hoc monotherapy subgroup analysis.
