Study Endpoints

Primary Endpoints

Part 1: Area Under the Plasma Concentration-time Curve From Dosing to Infinity (AUC0-inf) of MK-7655 in Combination With PRIMAXIN®
Predose and 0.08, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4.5, 6, 8, 10, and 14 hours postdose

AUC0-∞ is a measure of the mean (extrapolated) plasma drug concentration after dosing to infinity.

Dialysis Clearance (CLD) of MK-7655 in Participants With End-stage Renal Diseases Requiring Hemodialysis (ESRD/HD)
1, 1.5, 2, 2.5, 3, 3.5, 4, and 4.5 hours postdose

The CLD of MK-7655 was determined in ESRD/HD participants for 4.5 hours during HD. The formula for calculating CLD was: CLd = (1-Hct)\*QB\*\[(pre-dialyzer concentration - post-dialyzer concentration) / (pre-dialyzer concentration)\] where QB=350 mL/min and Hct=hematocrit.

Extraction Coefficient of MK-7655 in Participants With End-stage Renal Diseases Requiring Hemodialysis (ESRD/HD)
1, 1.5, 2, 2.5, 3, 3.5, 4, and 4.5 hours postdose

The extraction coefficient of MK-7655 was determined in ESRD/HD participants for 4.5 hours during HD. The formula for calculating extraction coefficient was: Extraction Coefficient = ABS\[100\*(post-dialyzer concentration - pre-dialyzer concentration) / pre-dialyzer concentration\].

Secondary Endpoints

Part 1: Concentration at End of Infusion (Ceoi) of MK-7655 in Combination With PRIMAXIN®
At 0.5 hours postdose
Part 1: Predicted Clearance (CLpred) of MK-7655 in Combination With PRIMAXIN®
Predose and 0.08, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4.5, 6, 8, 10, and 14 hours postdose
Part 1: Predicted Volume of Distribution During the Terminal Phase (VZpred) of MK-7655 in Combination With PRIMAXIN®
Predose and 0.08, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4.5, 6, 8, 10, and 14 hours postdose

Frequently asked questions about MK-7655

What is MK-7655 used for?

MK-7655, also known as relebactam, is an investigational small molecule being developed for infectious diseases, including complicated intra-abdominal infections, complicated urinary tract infections, and bacterial pneumonia. It is studied in combination with imipenem/cilastatin for these indications.

What does MK-7655 target?

MK-7655 is a beta-lactamase inhibitor that targets bacterial resistance mechanisms. It is combined with imipenem/cilastatin to restore the activity of imipenem against resistant bacteria. The drug is designed to treat infections caused by bacteria that produce beta-lactamase enzymes.

Who makes MK-7655?

MK-7655 is being developed by Merck & Company, Inc., which trades under the ticker symbol MRK on the New York Stock Exchange. The company is conducting clinical trials to evaluate the drug for various infectious disease indications.

What phase is MK-7655 in?

MK-7655 has completed Phase 1, Phase 2, and Phase 3 clinical trials. The most advanced trial was a Phase 3 study in bacterial pneumonia, which has been completed. The drug is investigational and not yet approved by regulatory authorities.

What clinical trials is MK-7655 in?

MK-7655 has been studied in several completed trials, including NCT01275170 (Phase 1, renal impairment), NCT01505634 (Phase 2, complicated urinary tract infection), NCT01506271 (Phase 2, complicated intra-abdominal infection), and NCT02493764 (Phase 3, bacterial pneumonia).

Is MK-7655 the same as relebactam?

Yes, MK-7655 is also known as relebactam. In clinical trials, it is often referred to as relebactam, particularly in combination with imipenem/cilastatin. The drug is being developed by Merck for treating serious bacterial infections.
