A Phase I Clinical Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Food Effects of a Single Oral VV119 Capsule in Healthy Chinese Volunteers

This study will consist of 2 parts: Part Ⅰ - Single Ascending Dose (SAD) study, Part Ⅱ - Food Effect (FE) study

Study Overview

• Status: Recruiting
• Conditions: Schizophrenia
• Intervention / Treatment: Drug: VV119(FE); Drug: VV119(SAD); Drug: VV119 Placebo(SAD)

Detailed Description

Part Ⅰ were designed as single-center, randomized, double-blind, placebo-controlled, dose-escalation trials to assess the safety, tolerability, pharmacokinetic (PK) of single oral doses of VV119 in healthy adult subjects.

Part Ⅱ is a single-center, randomized, open label, 3×3 crossover design to assess the food effects on PK of a single oral dose of VV119 in healthy adult subjects.
