Study Overview

• Status: Not yet recruiting
• Conditions: Renal Impairment; Hepatic Impairment
• Intervention / Treatment: Drug: SIM0417 600 mg; Ritonavir100 mg; Drug: SIM0417 375 mg; Ritonavir100 mg; Drug: SIM0417 750 mg; Ritonavir100 mg

Detailed Description

This is a multicenter, non-randomized, open-label, parallel controlled Phase I clinical study to evaluate the Pharmacokinetics, Safety and Tolerability of SIM0417 combined with ritonavir after a single dose in subjects with mild and moderate renal impairment, moderate hepatic impairment, normal renal function, and normal hepatic function.

Part A includes 4 cohorts, each of which plans to enroll 6-12 subjects, for a total of 24-48 subjects. Participants will be allocated into normal renal function or mild/moderate renal impairment groups based on their estimated glomerular filtration rate.

Part B includes 2 cohorts, each of which plans to enroll 6-12 subjects, for a total of 12-24 subjects. Participants will be allocated into normal hepatic function or moderate hepatic impairment groups based on their Child-Pugh score.

Each subject will receive SIM0417 combined with ritonavir administration. SIM0417 is single-dosed, and ritonavir is administered 12 hours before SIM0417 administration (-12 hours), at the time of SIM0417 administration (0 hour), 12 hours (12 hours) after SIM0417 administration, and 24 hours (24 hours) after SIM0417 administration.
