Effect of Rifampicin on the Pharmacokinetics of HRS-1167 in Healthy Subjects

A Single Center, Single Arm, Open, Fixed Sequence Study on the Pharmacokinetic Effects of Rifampicin on Oral Administration of HRS-1167 in Healthy Subjects

The primary objective of the study is to evaluate the effect of rifampicin on pharmacokinetics of healthy adult subjects after oral administration of HRS-1167 tablets. The secondary objective of the study is to evaluate the safety of HRS-1167 alone and when co-administered with rifampicin.
