A PHASE 1, OPEN-LABEL STUDY TO EVALUATE THE PHARMACOKINETICS AND SAFETY OF XNW4107, IMIPENEM AND CILASTATIN ADMINISTERED CONCURRENTLY AS INTRAVENOUS INFUSION TO SUBJECTS WITH VARIOUS DEGREES OF RENAL FUNCTION

XNW4107-003

This is a Phase 1, open-label study to assess the PK, safety and tolerability of XNW4107, imipenem and cilastatin administered by 60-minute (60-min) IV infusion to adults with various degrees of renal insufficiency as compared to subjects with normal renal function.
