• Clinically- or bacteriologically-documented moderate-to-severe (non life-threatening) diabetic foot infection that requires treatment with IV antibiotics
• Wound site or lesion with purulent drainage from the primary site of infection OR at least 3 of the following: fever, white blood count (WBC) >10,000 with >5% immature neutrophils, local periwound erythema (redness) extending >1 cm away from the wound edge or abscess cavity, localized periwound edema (swelling), localized tenderness or pain, localized fluctuance, lymphangitis associated with a skin lesion, localized warmth, and localized induration (limb brawny edema)
• Negative skin test result for allergy to penicillin

Exclusion Criteria

• Pregnant, breastfeeding, or intending to become pregnant or father a child during the course of the study
• Presence of uncomplicated skin infection such as the following: simple abscesses, impetigo, furunculosis, carbunculosis, or folliculitis in normal hosts; infected burn wound; necrotizing fasciitis; suspected osteomyelitis contiguous with the skin or skin structure infection for which removal of the infected bone is not likely to occur within 2 days of initiation of IV study therapy; wound infection that contains concomitant gangrene that cannot be adequately removed with debridement; infection likely to require a below-the-knee amputation (BKA); infection involving prosthetic material; or evidence of indwelling foreign material (such as prosthetic or surgical hardware) near the infected site that cannot be removed by surgical debridement
• Treatment within 3 days prior to the eligibility screening with >24 hours of systemic antibiotic therapy known to be effective against the presumed or documented etiologic pathogen(s)
• History of serious allergy, hypersensitivity (e.g., anaphylaxis), or any serious reaction to carbapenem antibiotics (such as ertapenem sodium, imipenem cilastatin, meropenem, or doripenem) piperacillin/tazobactam sodium, amoxicillin/clavulanate, any penicillins, any cephalosporins, or any other β-lactam agents
• Need for concomitant systemic antibacterial(s) in addition to those designated in the 2 study groups (with the exception of the addition of vancomycin for Enterococcus ssp. or methicillin-resistant Staphylococcus aureus [MRSA])
• Insufficient vascular perfusion to the affected limb
• Rapidly progressive or terminal illness
• Requirement or anticipation of need for dialysis (peritoneal dialysis, hemodialysis, or hemofiltration)
• Acute hepatitis or acute decompensation of chronic hepatitis
• Human immunodeficiency virus (HIV)-positive with a clinical diagnosis of acquired immune deficiency syndrome (AIDS), or an absolute neutrophil count (ANC) of <1000 cells/mm^3
• Immunosuppression
