The trial aims to evaluate the safety, tolerability, and pharmacokinetics (PK) of YR011 in healthy adult participants.\n\nThe trial has two stages: Single Ascending Dose (SAD) and Multiple Ascending Dose (MAD), with about 64 participants total (32 per stage). Participants are divided into 4 cohorts per stage (8 people per cohort), randomized 6:2 to receive YR011 or placebo in a double-blind manner. For the SAD stage, 4 dose levels are tested as a single oral dose under fasting conditions; for the MAD stage, 4 dose levels are given twice daily for 7 days plus one extra dose on Day 8.\n\nKey procedures include screening (up to 28 days before enrollment), baseline assessments, drug administration, and follow-up (7 days for SAD, 14 days for MAD). Safety is the primary endpoint (measured by treatment-related adverse events), with secondary endpoints including PK parameters (e.g., plasma concentration, half-life) and dose accumulation. Eligible participants are 18-60 years old, healthy, and able to comply with trial procedures; those with major diseases, drug allergies, or recent medication use are excluded.\n\nThe trial follows ICH-GCP and FDA regulations, with a Safety Review Committee overseeing dose escalation and safety monitoring.
