Summary
Brief summary
This study is a single center, randomized, placebo-controlled, double-blind study of CT-1500
in healthy volunteers. The study will evaluate the safety, tolerability and pharmacokinetics
of single ascending doses and multiple ascending doses of orally administered CT-1500
compared to placebo.
