Brief Summary

This study is a single-site, single-dose, non-randomized, open-label study to assess the absorption, metabolism, and excretion profile of [14C]X842 in healthy adult male subjects. The study plans to enroll 6 to 8 healthy male subjects in China to ensure at least 4 evaluable subjects.

Detailed Description

The healthy male subjects will be screened no more than 14 days before the dose (D-14 through D-3) and admitted to the clinical research center 2 days before the dose (D-2). The subjects will receive a single oral administration of approximately 50 mg/100 µCi [14C]X842 suspension orally on an empty stomach on day 1.

Urine and feces samples will be all collected from the subjects before and at specified intervals between 0 and 312 hours after taking the drug and blood samples will be collected at specified time points between 0 and 216 hours before and after taking the drug.
