About

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.

Full 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.

Body mass index is between 18 and 32 kg/m2 (both inclusive), the weight of male subjects ≥ 50 kg, the weight of female subjects ≥ 45 kg
Considered generally normal or abnormal with no clinical significance upon medical history, physical examination, vital signs, ECG, and clinical laboratory tests, as judged by the Investigator
Female subjects of child-bearing potential must agree to use highly effective contraceptive methods 1 month before the screening, during the entire study, and within 3 months after the end of this study, and have no egg donation plan within 3 months of study end. The male partner of a female subject must agree to use condoms during the screening, entire study, and within 3 months after the end of this study.
