Phase 1 Study in Healthy Participants and Participants With Kidney Dysfunction

A randomized, double-blind, placebo-controlled, dose-escalation clinical trial to evaluate the safety, tolerability, pharmacokinetic characteristics, and the impact of food on pharmacokinetics of oral HS-10398 in Chinese healthy participants, and a clinical trial to assess the pharmacokinetic characteristics of oral HS-10398 in Chinese participants with kidney dysfunction

This is a phase 1, first-in-human, randomized, double-blind, placebo-controlled, dose-escalation clinical trial. The primary objective is to evaluate the safety, tolerability, and pharmacokinetic characteristics of single and multiple oral doses of HS-10398 in Chinese healthy participants. The secondary objective is to assess the impact of food on the pharmacokinetics of single oral doses of HS-10398 in Chinese healthy participants, as well as to evaluate the pharmacokinetic characteristics of oral HS-10398 in Chinese participants with kidney dysfunction.
