Primary Outcome Measures:
  • The proportion of subjects with clinical outcome of cure [ Time Frame: 26-30 days after start of study drug administration ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The proportion of subjects with microbiological outcome of success [ Time Frame: 26-30 days after start of study drug administration ] [ Designated as safety issue: No ]
  • The proportion of subjects with clinical outcome of cure, failure, or indeterminate and microbiological outcome of success at the end of therapy and late follow-up [ Time Frame: 4-45 days after start of study drug administration ] [ Designated as safety issue: No ]
  • Safety will be evaluated in the safety population by presenting summaries of adverse events, clinical laboratory tests, vital signs, and physical examinations [ Time Frame: All study visits through the Late Follow Up (38-45 Days after completion of study drug administration) ] [ Designated as safety issue: No ]

Enrollment: 500
Study Start Date: October 2011
Study Completion Date: September 2013
Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: CXA-201 and Metronidazole as treatment for cIAI Drug: CXA-201 and metronidazole
CXA-201 IV infusion (1500mg q8h) and metronidazole IV infusion (500mg q 8h) for 4-14 days
Active Comparator: Meropenem as treatment for cIAI Drug: Meropenem
Meropenem IV infusion (1000mg q8h) for 4-14 days

Detailed Description:

Approximately, 500 subjects will be enrolled into this study, randomized 1:1 to receive CXA-201 and metronidazole or comparator (meropenem). Subject participation will require a minimum commitment of 38 days and a maximum of 45 days. An End of Treatment (EOT) visit will occur within 24 hours following the last dose of study drug administration/drug discontinuation. A Test of Cure (TOC)/Safety visit will be conducted 26 to 30 days following the first dose of study drug administration. A Last Follow-up (LFU) visit will be conducted 38 to 45 days after the first dose of study drug.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnoses of cIAI.
  • Subject requires surgical intervention (e.g., laparotomy, laparoscopic surgery, or percutaneous draining of an abscess) within 24 hours of (before or after) the first dose of study drug.

Exclusion Criteria:

  • Simple appendicitis; acute suppurative cholangitis; infected necrotizing pancreatitis; pancreatic abscess; or pelvic infections.
  • Complicated intraabdominal infection managed by staged abdominal repair (STAR), open abdomen technique including temporary closure of the abdomen, or any situation where infection source control is not likely to be achieved.
  • Use of systemic antibiotic therapy for IAI for more than 24 hours prior to the first dose of study drug, unless there is a documented treatment failure with such therapy.
  • Have a concomitant infection at the time of randomization, which requires non-study systemic antibacterial therapy in addition to IV study drug therapy. (Drugs with only gram-positive activity [e.g., daptomycin, vancomycin, linezolid] are allowed).
  • Severe impairment of renal function (estimated CrCl < 30 mL/min), or requirement for peritoneal dialysis, hemodialysis or hemofiltration, or oliguria (< 20 mL/h urine output over 24 hours).
  • The presence of hepatic disease at baseline.
  • Considered unlikely to survive the 4 to 5 week study period.
  • Any rapidly-progressing disease or immediately life-threatening illness (including respiratory failure and septic shock).
  • Have a documented history of any moderate or severe hypersensitivity or allergic reaction to any β-lactam antibacterial (a history of a mild rash followed by uneventful re-exposure is not a contraindication to enrollment), including cephalosporins, carbapenems, penicillins, or ß-lactamase inhibitors, or metronidazole, or nitroimidazole derivatives.
  • Women who are pregnant or nursing.
