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.

             drug infusion.

          -  Has received treatment or plans to receive treatment with any carbapenem antibiotic

          -  Has used or plans to use any of the following medications, which are organic anion
             transporter (OAT) 1 or OAT3 inhibitors, within 1 week prior to screening or at any
             point between screening and the last PK sample collection: cimetidine, probenecid,
