Phase 1 |
Detailed Description
This is a phase 1, open-label, fixed-sequence, 2-period drug-drug interaction study which was divided into three cohorts.
Cohort 1: to evaluate the effect of the CYP3A4 inhibitor itraconazole on the pharmacokinetics of SIM0417 and ritonavir in healthy participants.
Cohort 2: to evaluate the effect of the CYP3A4 inducer rifampicin on the pharmacokinetics of SIM0417 and ritonavir in healthy participants.
Cohort 3: to evaluate the effect of SIM0417/ ritonavir on the pharmacokinetics of CYP3A4 substrate midazolam in healthy participants.
