Clinical Trial Summary

The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of CBP-174 after a single oral dose in healthy adult subjects.

Description:

This is a randomized, double-blind, placebo-controlled, single ascending dose study in healthy subjects to evaluate the safety, tolerability and pharmacokinetics of CBP-174 compared to placebo. The study plans to set 6 dose escalation cohorts with single oral dose. Each subject will receive only one dose regimen in this study and the total duration to participate the study is approximately 1 to 4-week.
