Clinical Trial Summary

This research project is being conducted to look at the pharmacokinetics (PK; how the human body processes a substance), safety, and tolerability of a single dose of ETX2514 and sulbactam (ETX2514SUL) when concurrently administered by separate intravenous (IV) infusion in participants with various degrees of renal impairment (RI), in participants with end-stage renal disease (ESRD) who are on hemodialysis (HD), and in healthy matched control participants with normal renal function.

Description:

This Phase 1, open-label, non-randomized study evaluates the PK, safety, and tolerability of a single concurrent IV infusion of ETX2514SUL in participants with various degrees of RI, in participants with ESRD who are on HD, and in healthy matched control participants with normal renal function.

Participants will be enrolled into five cohorts, according to renal function status, and will receive an IV infusion of ETX2514SUL (single dose of up to 1000 milligrams [mg] ETX2514 and 1000 mg sulbactam given by concurrent 3-hour IV infusion). Participants in Cohort 5 will receive the ETX2514SUL infusion both post-HD (Period 1) and pre-HD (Period 2).
