Effect of Rifampicin on the Pharmacokinetics of SHR6390 in Healthy Subjects

Study Overview
=================
Brief Summary
-----------------
The primary objective of the study is to evaluate the effect of rifampicin on pharmacokinetics of healthy Chinese adult subjects after oral administration of SHR6390 tablets. The secondary objective of the study is to evaluate the safety of SHR6390 alone and when co-administered with rifampicin.
