• Minor abscesses, unless present with one of the ABSSSI types
• Any infection expected to require other antimicrobial agents in addition to study drug
• Receipt of > 24 hours of systemic antibiotic therapy in the 14 days before enrollment unless one of the following is documented: the subject received a single dose of a short-acting antibacterial drug 3 or more days before clinical trial enrollment for surgical prophylaxis or recently completed treatment with an antibacterial drug for an infection other than ABSSSI and the drug does not have antibacterial activity against bacterial pathogens that cause ABSSSI
• Receipt of more than 1 dose of a potentially effective antibacterial agent for treatment of the ABSSSI under study prior to enrollment
• Receipt of chronic anti-inflammatory therapy for longer than 14 days before enrollment
