Eligibility criteria:

        -  Inclusion Criteria:

               1. Willingness to comply with all study activities and procedures and to provide
                  signed, written informed consent prior to any study procedures. If a subject is
                  unable to provide informed consent due to their medical condition, the subject's
                  legal representative will be provided with study information in order for consent
                  to be obtained.

               2. Hospitalized male or female, ≥18 years of age.

               3. Weight ≤185 kg.

               4. Have a confirmed diagnosis of a serious infection, specifically cUTI or AP, cIAI,
                  HABP, VABP, and/or bacteremia, requiring administration of IV antibacterial
                  therapy.

               5. Have a known or suspected Carbapenem-Resistant Enterobacteriaceae (CRE)
                  infection.

               6. Expectation, in the opinion of the Investigator, that the subject's infection
                  will require treatment with IV antibiotics for a minimum of 7 days.

               7. Expectation that subjects with an estimated creatinine clearance <10 ml/min
                  (Cockcroft-Gault) will receive hemodialysis at least 2 times per week.

               8. For cUTI & AP subjects only: expectation, in the judgment of the Investigator,
                  that any indwelling urinary catheter or instrumentation (including nephrostomy
                  tubes and/or indwelling stents) will be removed or replaced (if removal is not
                  clinically acceptable) before or as soon as possible, but not longer than 12
                  hours, after randomization.

                  For cIAI subjects only: • Expectation, in the judgment of the investigator, that
                  operative drainage/debridement/removal (including open laparotomy, percutaneous
                  drainage, or laparoscopic surgery) of any intra-abdominal collection or other
                  potential source of intra abdominal infection will be performed;

                  • Expectation that cultures from the aforementioned procedure (including open
                  laparotomy, percutaneous drainage, or laparoscopic surgery) will be sent for
                  microbiological evaluation, including gram stain, culture and susceptibility
                  testing, and Vabomere susceptibility testing.

               9. Female subjects of childbearing potential, including those who are less than 2
                  years post menopausal, must agree to, and comply with, using 2 highly effective
                  methods of birth control (i.e., condom plus spermicide, combined oral
                  contraceptive, implant, injectable, indwelling intrauterine device, sexual
                  abstinence, or a vasectomized partner) while participating in this study. In
                  addition, all women of childbearing potential must agree to continue to use 2
                  forms of birth control throughout the study and for at least 30 days after
                  administration of the last dose of study drug.

          -  Exclusion Criteria:

               1. History of any significant hypersensitivity or severe allergic reaction to any
                  beta-lactam antibiotics (e.g., cephalosporins, penicillins, carbapenems, or
                  monobactams).

               2. Known or suspected likely infection with New Delhi metallo- (NDM), Verona
                  integron-encoded metallo- (VIM), or IMP-metallo-beta-lactamases or oxacillinase-
