Study Description
Brief Summary
This study aims to obtain plasma pharmacokinetic (PK) data and characterize the PK profile of imipenem (IMI), cilastatin (CIL), and relebactam (REL) following administration of a single intravenous (IV) dose of MK-7655A (a fixed ratio combination of imipenem/cilastatin/relebactam), hereafter referred to as IMI/REL.

Outcome Measures
Primary Outcome Measures
- Imipenem (IMI) Area Under the Concentration Time Curve From Time 0 to Infinity (AUC0-∞) [30 minutes (min) before start of drug infusion (DI) and 10 min after the end of DI for all cohorts; 1.5 to 2.5 hours (hrs) and 4.5 to 6 hrs after start of DI for Cohorts 1-4; 2 to 5 hrs and 6 to 12 hrs after start of DI for Cohort 5]
Area under the concentration time curve from time 0 to infinity (AUC0-∞) of plasma imipenem (IMI) was calculated. AUC0-∞ is the area under the plasma concentration versus time curve from time zero (pre-dose) to extrapolated infinite time.
