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.

Inclusion Criteria:

• Healthy participants aged from 18 to 64 years
• Subjects need to fully understand the research content and process, as well as possible adverse reactions, and voluntarily signed Informed Consent Form

• Has clinically significant ECG abnormalities, such as QT interval corrected according to Fridericia formula(QTcF), >450 ms (males), >470 ms (females)
• Has participated in another clinical trial involving drugs or medical devices within the month prior to screening and received investigational drugs or used medical devices, or within 5 half-lives of the investigational drugs from another trial at the time of screening, whichever is longer
