Safety and Pharmacokinetics Study of Single Ascending Doses of VV116 in Healthy Volunteers
Study Details
Study Description
Brief Summary
The study consists of 5 dose groups, starting at 25 mg, 6 subjects in 25 mg group, and 8 subjects in each other group (male or female), randomly assigned to study drug or placebo group to evaluate the safety, tolerability and PK characteristics. The subject number of single dose group may increase or decrease depending on the safety and PK data obtained. The dose levels are planned at 25 mg, 200 mg, 400 mg, 800 mg and 1200 mg. Based on observed tolerability and safety data or obtained PK data, adjustments are allowed at all dose levels in the clinical trial.

Phase 1 |
Detailed Description
4 subjects in the 25 mg dose group will receive VV116 tablets and the other 2 subjects will receive placebo. In other dose groups, 6 subjects in each group will receive VV116 tablets and 2 subjects will receive placebo. 25mg,800mg and 1200 mg dose group will be given by sentinel administration (i.e. 1 study drug, 1 placebo). Subjects who receive sentinel administration will be observed for 48 hours and investigator will evaluate the safety parameters (including symptoms, vital signs, physical examination, etc.).
