safety and pharmacokinetics of hrs-1780 in healthy subjects and subjects with impaired renal function

Conditions: Chronic Kidney Disease

Summary: this is a multicenter, non-randomized, open-label, parallel-controlled study. the main objective is to evaluate the safety and pharmacokinetics of hrs-1780 in subjects with mild and moderate renal impairment versus healthy subjects, and to provide a basis for dose selection of hrs-1780 in patients with chronic kidney disease.
