Study Overview
=================
Brief Summary
-----------------
This study is a single-center, open-label, single-dose clinical pharmacokinetic study. The purpose of this study is to investigate the absorption properties, as well as to evaluate the mass balance and elucidate the pathways of biotransformation after a single oral dose of 400mg, 200μCi [14C] APG-2575 to healthy subjects.
