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.
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.
