The Absorption, Metabolism and Excretion of [14C]Ensartinib in Human

Summary

This is a single-center, open-label, single-dose phase I study to investigate the absorption, metabolism and excretion of \[14C\] Ensartinib in healthy Chinese male subjects. The study will be conducted into two steps：Firstly, 2 subjects are enrolled in to participate in the pilot study to grope for the completion date of plasma, urine and feces sampling on the 3rd day post-dose and onwards. Then, the collection time of blood and excreta samples (urine and feces) from the subsequent 4-6 subjects will be adjusted according to the pilot study.
