简要总结
This is a phase 1, open-label, fixed-sequence, 2-period drug-drug interaction study to evaluate the pharmacokinetic interactions of itraconazole, rifampicin, midazolam, and SIM0417/ritonavir in healthy Chinese subjects.
详细描述
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.

And female subjects of Cohort 1 agree to take recognized effective contraceptive measures during the study period and for the next menstrual cycle after the last dose of the study drug (male subjects up to 1 month after the last dose of the study drug ). Subjects of cohort 2 agree to take recognized effective contraceptive measures during the study period and within 1 month after the last dose of the study drug. Subjects of cohort 3 agree to take recognized effective contraceptive measures during the study period and within 3 months after the last dose of the study drug. Female subjects had been using effective contraception for 14 days prior to screening.
