a clinical trial of xzp-6019 tablets in healthy subjects

Conditions: Non-alcoholic Fatty Liver Disease

Summary: this study will consist of 3 parts: part a - single ascending dose (sad) phase, part b - food effect (fe) phase, and part c - multiple ascending dose (mad) phase.

part a and part c studies were designed as single-center, randomized, double-blind, placebo-controlled, dose-escalation trials to assess the safety, tolerability, pharmacokinetic (pk) and pharmacodynamic (pd) profiles of single and multiple oral doses of xzp-6019 tablets in healthy adult subjects. part b is a single-center, randomized, open label, 2×2 crossover design to assess the food effects on pk of a single oral dose of xzp-6019 tablets in healthy adult subjects.
