Brief Summary:
The purpose of this study is to assess the efficacy and safety of delafloxacin administered as IV and oral formulation in comparison with Best Available Therapy (BAT) in patients with superficial or deep incisional surgical site infection following a cardiothoracic/related leg or abdominal surgery.

Condition or disease Intervention/treatment Phase
Surgical Site Infection Drug: Delafloxacin Drug: Vancomycin Drug: Linezolid Drug: Piperacillin/Tazobactam Drug: Tigecycline Phase 3

Detailed Description:

This is a randomized, observer-blinded, active-controlled, parallel-group, multicenter, phase IIIb study for the treatment of incisional, superficial or deep, surgical site infection after cardiothoracic /related leg or abdominal surgery (i.e patients who are at risk of microbiologically resistant infections). IV to be switched to oral delafloxacin will be compared to treatments that represent the best available therapy (BAT) for either cardiothoracic/related leg or abdominal surgical site infection (SSI).

Approximately 600 male and female eligible patients will be randomly assigned in a 1:1 ratio to receive delafloxacin or BAT. For patients who are randomised to BAT, the investigator will choose one out of two treatments available (two available for the cardiothoracic/related leg and two available for abdominal SSI) as most appropriate for patient characteristics and local epidemiological pattern.

Duration of study depends on treatment duration (range: minimum 5 to maximum 14 days, as per Investigator's judgment) followed by visits up to 30 days after end of treatment.

Patients will be hospitalized from Screening (within 30 days from surgery) and will remain hospitalized until considered improved or cure as per Investigator's judgment.

Primary Outcome Measures :
  1. Clinical Success at Test Of Cure visit [ Time Frame: 7-14 days after last dose ]
    Clinical Success defined as the clinical response of "Cure" or "improved"

Secondary Outcome Measures :
  1. Hospital Infection Related Length of Stay (IRLOS) [ Time Frame: up to 14 days ]
    Length of Stay since beginning of therapy till patient stabilization and considered suitable for hospital discharge

  2. Hospital Length of Stay (LOS) [ Time Frame: up to 45 days (Late Follow Up visit) ]
    Length of Stay since Screening till actual hospital discharge

  3. Eligibility to switch to oral formulation according to blinded observer's assessment [ Time Frame: up to 14 days ]
    Blinded assessment based on patient stabilization and ability to tolerate OS diet

  4. Microbiological response [ Time Frame: up to 14 days (End Of Treatment visit) and 7-14 days after last dose (Test Of Cure visit) ]
    Documented or presumed eradication or persistence
