Primary Outcome Measures:
  • Objective response of ≥20% reduction in lesion erythema area compared to baseline at 48 to 72 hours after initiation of treatment as determined by digital measurements of the leading edge. [ Time Frame: Baseline and at 48 to 72 hrs ] [ Designated as safety issue: No ]
    Digital photography of the infection area will be obtained at Screening, Day 1, Day 2, twice on Day 3 (12 hours apart), Day 4, Day 5, End of Treatment, Follow up, and Late Follow up using the equipment provided. The photography will be analyzed for planimetry measurements and used in the objective response assessments.


Secondary Outcome Measures:
  • Investigator-assessed response of signs and symptoms of infection at the Follow up Visit (EMA primary endpoint) [ Time Frame: Up to Day 14±1 ] [ Designated as safety issue: No ]
  • Investigator-assessed response of signs and symptoms of infection in patients with a baseline BMI ≥30 at the Follow up Visit [ Time Frame: Up to14 ± 1 days after initiation of treatment ] [ Designated as safety issue: No ]
  • Investigator-assessed response of signs and symptoms of infection at the Late Follow-up Visit [ Time Frame: Up to Day 28 ] [ Designated as safety issue: No ]
  • Reduction of erythema of ≥30% at 48 to 72 hours when digital measurements are used [ Time Frame: at 48 and 72 hrs ] [ Designated as safety issue: No ]
  • Reduction in pain at End of Treatment as measured by ePRO system [ Time Frame: Up to Day 14 ] [ Designated as safety issue: No ]
  • Microbiological response of eradicated (documented or presumed) at the Follow-up Visit in all patients [ Time Frame: Up to Day 14 ] [ Designated as safety issue: No ]

  Eligibility

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

Inclusion Criteria:

  • Adult (≥ 18 years of age) men or women with a diagnosis of ABSSSI (cellulitis/erysipelas, wound infection, major cutaneous abscess, or burn infection) with at least two signs of systemic infection
  • In the opinion of the investigator, the subject must require and be a suitable candidate for IV antibiotic therapy, and the subject must be able and willing to comply with protocol requirements

Exclusion Criteria:

  • A medical history of significant hypersensitivity or allergic reaction to quinolones, beta-lactams, vancomycin, or vancomycin derivatives according to the judgment of the investigator.
  • Women who are pregnant or lactating.
  • Any chronic or underlying skin condition at the site of infection that may complicate the assessment of response, including infection involving a prosthetic joint, human or animal bite, osteomyelitis, decubitus ulcer, diabetic foot ulcer, septic arthritis, mediastinitis, necrotizing fasciitis, anaerobic cellulitis, or synergistic necrotizing cellulitis, myositis, tendinitis, endocarditis, sustained shock, gangrene or gas gangrene; burns covering ≥10% of body surface area; severely compromised immune system, severely impaired arterial blood supply to an extremity with an ABSSSI, deep vein thrombosis or superficial thrombophlebitis, and requiring either an amputation or multiple debridement procedures.
  • Any underlying disease that, in the opinion of the investigator, could interfere with the subject's ability to participate in the study including severe cardiac disease, known history of liver disease, end-stage renal disease, malignancy, psychiatric disorder, ongoing treatment for seizures or untreated history of seizures, or life expectancy of < 3 months.
