Summary

This study uses a tiny amount of radioactive labeling to track how the experimental drug D-2570 moves through the body and is eliminated. Eight healthy Chinese men will provide blood, urine, and stool samples to measure the drug's breakdown and excretion. The goal is to understand the drug's metabolism and safety, not to treat any disease.
