This study consists of 2 phases. In the dose-escalation phase, up to 5 dose levels of HS-10241 (100 mg/day, 200 mg/day, 340 mg/day, 500 mg/day, and 700 mg/day) will be investigated with a sequential "3+3" design (3 or 6 participants in every dose level). Participants will have a single-dose pharmacokinetic (PK) run-in period (7 days). Following the first dose, participants will enter a 1 week treatment-free period to evaluate safety and single-dose PK. If no dose-limiting toxicities (DLTs) are observed during the 1-week period, HS-10241 administration will resume at the same dose level.
