Primary Outcome Measures:
  • Clinical Cure [ Time Frame: End of Treatment (10 days after starting study drug) + 2 days ]
    Clinical Cure is defined as: • Resolution of Diarrhea (ROD) (≤ 3 unformed bowel movement (UBM) per day for at least 2 consecutive days) on study treatment and maintained for 2 days after EOT, AND • No additional antimicrobial treatment active against Clostridium difficile-associated diarrhea (CDAD) or fecal microbiota transplant (FMT) between first dose of study drug and 2 days after EOT (inclusive)

Secondary Outcome Measures:
  • Sustained Cure [ Time Frame: End of Treatment (10 days after starting study drug) + 28-32 days ]
    Sustained cure is defined for each subject having Clinical Cure and no recurrence

  • Time to Resolution of Diarrhea [ Time Frame: Baseline to End of Treatment (10 days after starting study drug) ]
    The time between the first dose of study drug and Resolution of Diarrhea.

  • Absolute change from baseline in clostridium difficile-associated diarrhea (CDAD) DaySyms PRO daily score [ Time Frame: Baseline to End of Treatment (10 days after starting study drug) + 2 days ]
    Change from baseline to End of Treatment + 2 days in CDAD Symptoms as measured by the DaySyms Patient Reported Outcome (PRO).

Estimated Enrollment: 640
Study Start Date: November 2013

Cadazolid 250 mg as oral suspension twice daily.
Other Name: ACT-179811
Drug: Vancomycin-matching placebo
Placebo capsules matching vancomycin and administered orally 4 times per day
Active Comparator: Vancomycin
Subjects receive oral vancomycin 125 mg qid and oral cadazolid-matching placebo bid for 10 days

Detailed Description:
Subjects selected to participate in the study are treated either with cadazolid or vancomycin for 10 days. At the end of treatment, clinical cure is assessed; subjects are then followed-up to assess any disease recurrence.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)

Exclusion Criteria:

  • More than one previous episode of CDAD in the 3-month period prior to randomization.
  • Evidence of life-threatening or fulminant CDAD.
  • Likelihood of death within 72 hours from any cause.
  • History of inflammatory colitides, chronic abdominal pain, or chronic diarrhea.
