A Mass Balance Study of [14C]ABSK011

This study is a single-site, open-label, single-cohort, single-dose study to assess the absorption, metabolism, and excretion profile of \[14C\] ABSK011 in healthy adult male subjects. The study plans to enroll 6 to 8 healthy male subjects to ensure at least 6 evaluable subjects.

Participants will be screened no more than 14 days before the dose (D-14 through D-3) and admitted to the clinical trial unit 2 days before the dose (D-2). Participants will receive a single oral administration of approximately 200 mg/120 µCi \[14C\]ABSK-011 suspension after a low-fat breakfast on day 1 morning.

Urine and stool samples will be collected from participants before and at specified intervals between 0 and 192 hours after taking the drug and blood samples will be collected at specified time points between 0 and 120 hours before and after taking the drug.
