infectious.

ischemic bowel without perforation.
3. Patient has simple cholecystitis or gangrenous cholecystitis without rupture, or
simple appendicitis, or acute suppurative cholangitis; or infected necrotizing

or marsupialization.
5. Patient known at study entry to have a complicated intra-abdominal infection caused by
pathogens resistant to the study antimicrobial agents.
6. Patient needed effective concomitant systemic antibacterials (oral, IV, or
intramuscular) or antifungals in addition to those designated in the 2 study groups,
except vancomycin, linezolid, or daptomycin if started for known or suspected
methicillin-resistant Staphylococcus aureus (MRSA) or Enterococcus spp. as per
clinical study protocol (CSP).
7. Patient has perinephric infections or an indwelling peritoneal dialysis catheter.
8. Patient has suspected intra-abdominal infections due to fungus, parasites (e.g.,
amoebic liver abscess), virus, or tuberculosis.
9. Patient has a known history of serious allergy, hypersensitivity or any serious
reaction to carbapenem antibiotics, or to other ß-lactam antibiotics
10. Patient known to have any of the following laboratory values as defined below:
1. Hematocrit <25% or hemoglobin <8 g/dL
2. Absolute neutrophil count <1000/mm3
3. Platelet count <75,000/mm3

hyperbilirubinemia was directly related to the acute infection or known Gilbert's
disease
5. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) >3 x ULN
values at Screening. Patients with elevations of AST and/or ALT up to 5 x ULN
will be eligible if these elevations are acute and directly related to the
infectious process being treated. This must be documented
6. Alkaline phosphatase (ALP) >3 x ULN. Patients with values >3.0 x ULN and <5.0 x
ULN are eligible if this value is acute and directly related to the infectious
process being treated. This must be documented.
7. Estimated creeatinine clearance <50 mL/min
11. Patient has a body mass index >45 kg/m2.
12. Patient has APACHE II score >30.
13. Patient considered unlikely to survive the 4-week study period or has a rapidly
progressive or terminal illness, including septic shock that was associated with a
high risk of mortality.
14. Patient unlikely to respond to 10-14 days of treatment with antibiotics.
15. Patient received systemic antibacterial agents within the 72-hour period prior to
study entry, unless either of the following pertained:
a. Patient has a new infection (not considered a treatment failure) and both of the
following were met: i. Patient received no more than 24 hours of total prior
antibiotic therapy ii. Patient received =1 dose of a treatment regimen
post-operatively and antibiotics were not received more than 6 hours post-procedure.
b. Patient considered to have failed the previous treatment regimen i.e.,
pre-operative treatment of any duration with non-study systemic antimicrobial therapy
for peritonitis or abscess permitted provided that all of the following are met: i.
The treatment regimen had been administered for at least 72 hours and was judged to
have been inadequate ii. The patient had an operative intervention that was just
completed or was intended no more than 24 hours after study entry iii. Findings of
infection were documented at surgery iv. Specimens for bacterial cultures and
susceptibility testing were taken at operative intervention v. No further non-study
antibacterials were administered after randomization.
16. Patient has a concurrent infection that may interfere with the evaluation of response
to the study antibiotic.
17. Patient receiving hemodialysis or peritoneal dialysis.
18. Patient has a history of acute hepatitis in the recent past (3 months prior to study
entry), chronic hepatitis, cirrhosis, acute hepatic failure, or acute decompensation
of chronic hepatic failure.
19. Patient has past or current history of epilepsy or seizure disorders excluding febrile
seizures of childhood.
20. Patient immunocompromised as evidenced by any of the following:
1. Human immunodeficiency virus infection, with either a recent (in the past 6
months) acquired immune deficiency syndrome-defining condition or a CD4 + T
lymphocyte count <200/mm3
