TREMHANCE: A Study to Investigate the Safety and Effectiveness of SAR448851 in Participants With Early Alzheimer's Disease
This clinical study is investigating whether an oral study drug called SAR448851 is safe and effective at helping slow Alzheimer's disease by activating the brain's own cleanup cells — called microglia — which help clear harmful proteins that build up in the brain.
This study has ethical approval from Bellberry (2026-04-541) and The Alfred Hospital Human Research Ethics Committee.
