研究概览
简要总结
This study is a Phase 1, single-center, open-label, single-dose study to evaluate (1) the absorption, metabolism, and excretion patterns of a single dose of [14C] PA-824, and (2) the pharmacokinetics, safety, and tolerability of a single oral-suspension dose of unlabeled PA-824 in healthy adult male subjects. Unlabeled PA-824 and [14C]-PA-824 will be administered together in an oral-suspension formulation. Enrollment is planned for one dose group of 6 subjects. All 6 subjects will receive the same treatment.
