Safety, Tolerability and Pharmacokinetics of CMS121, a Drug Candidate for Alzheimer's Disease, in Healthy Subjects

Completed · Phase 1 · Has a placebo group

Conditions studied: Alzheimer Disease

In brief

This is a randomized, double-blind study of CMS121 or placebo given as single and multiple escalating doses in normal healthy subjects. The study will be conducted in 4 parts: Part 1 will be a SAD study enrolling approximately 48 young subjects for a total duration of 36 days. Part 2 will be a MAD study enrolling approximately 32 young subjects for a total duration of 43 days, and Part 3 will be a MAD study enrolling approximately 8 elderly subjects for 43 days.
