In Brief
A Phase 3 clinical trial evaluating Placebo and Gantenerumab for Alzheimer's Disease. Completed, enrolled 389 participants across 131 sites in 22 countries.
Detailed Summary
Part 1 is a multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of gantenerumab in participants with mild Alzheimer disease. Participants will be randomized to receive either gantenerumab subcutaneously every 4 weeks or placebo subcutaneously every 4 weeks. Approved Alzheimer medication is allowed if on stable dose for 3 months prior to screening. Part 2 is an open-label extension (OLE). A positron emission tomography (PET) imaging substudy will be conducted within the main study. Eligible participants who provide separate informed consent will undergo PET imaging scans using the radioligand florbetapir as a pharmacodynamic measure of changes in brain amyloid load over time.
