Summary

This is a 2-part study of the pharmacokinetics (PK) of MK-7655. In Part I, the PK of a single 125 mg dose of MK-7655 given in combination with 250 mg of PRIMAXIN® (imipenem + cilastatin) will be determined in participants with impaired renal function and matched control participants. In Part II, the potential for renal insufficiency to affect non-renal clearance mechanisms will be investigated.
