Clinical Response at Test of Cure (TOC) in the Clinically Evaluable (CE) Population [ Time Frame: 14-21 days after the last dose of study drug ]
A Cure was defined as resolution of baseline signs and symptoms, or improvement to an extent that no additional antibiotic treatment is necessary. Failure was defined as the need for additional antibiotics, either because of lack of efficacy after at least 2 days (i.e., 4 doses) of study treatment or because of treatment-related adverse events (AEs), and/or the need for surgical intervention greater than 48 hours after study entry.

Clinical Response in Patients With Methicillin-resistant Staphylococcus Aureus (MRSA) [ Time Frame: 14-21 days after the last dose of study drug ]
A Cure was defined as resolution of baseline signs and symptoms, or improvement to an extent that no additional antibiotic treatment is necessary. Failure was defined as the need for additional antibiotics, either because of lack of efficacy after at least 2 days (i.e., 4 doses) of study treatment or because of treatment-related adverse events (AEs), and/or the need for surgical intervention greater than 48 hours after study entry.

Safety and Efficacy Study of a Fluoroquinolone to Treat Complicated Skin Infections
A Randomized, Double-Blind, Multicenter Study of the Safety and Efficacy of RX 3341 Compared With Tigecycline for the Treatment of Complicated Skin and Skin Structure Infections
The purpose of this study is to assess the efficacy, safety and tolerability of RX-3341 (delafloxacin), a fluoroquinolone, versus tigecycline, a glycylcycline antibacterial drug, in the treatment of complicated skin and skin structure infections.

Inclusion Criteria:

  • Adult (≥18 years of age) men or women with cSSSI
  • Diagnosis of one of the following 3 types of cSSSI: wound infection that has developed within 30 days of surgery, trauma, or a bite injury; abscess that has developed in the 7 days before enrollment; or cellulitis that has developed in the 7 days before enrollment
  • Sexually active men and women of childbearing potential must agree to use an acceptable form of contraception, as determined by the investigator, during participation in the study and for 30 days after the final dose of study drug
