A Phase I Clinical Trial of XZP-5610 Tablets in Healthy Subjects

Study Overview
=================
Brief Summary
-----------------
This study will consist of 3 parts: Part A - Single Ascending Dose (SAD) phase, Part B - multiple ascending dose (MAD) phase, and Part C - Food Effect (FE) phase.

Detailed Description
-----------------
Part A and Part B 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-5610 tablets in healthy adult subjects, and exploring preliminary food effects (non-high-fat meals) in the Part B study. Part C is a single-center, randomized, open, 2×2 crossover design designed to assess the foodeffects on PK of a single oral dose of XZP-5610 tablets in healthy adult subjects.

History of smoking within 3 months prior to screening, or a positive urine nicotine test at screening, or who cannot give up smoking throughout the study period Excessive daily intake of coffee, tea, cola, energy drinks, or other caffeinated beverages within 3 months prior to screening, with excess defined as more than 6 servings (one servingis approximately equal to 120 mg of caffeine). Major surgery, or donation or loss of blood over 400 mL within 3 months prior to administration. Participation in other clinical trials and treatment with investigational productinvestigational product within 3 months prior to administration. Taken any prescription, over-the-counter, nutraceutical, herbal or proprietary Chinese medicine within 4 weeks prior to administration (or less than 5 half-lives of the drug from the start of the trial). Women who are pregnant or breastfeeding, or of childbearing potential who are not using effective non-hormonal contraception (intrauterine device (IUD), barrier method with spermicide, or surgical sterilization, etc.) or are unwilling to continue using these methods during the trial until 6 months after discontinuation; men of childbearing potential who are unwilling to use physical methods of contraception during the trial until 6 months after discontinuation.
