What researchers measure

Primary outcomes

  1. Clinical cure rate

    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 End of treatment (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)

    Time frame: 2 days after 7-14 days treatment

  2. Recurrence rate

    Recurrence is defined as reappearance of diarrhea during the 8-week follow-up period.

    Time frame: Up to 10 weeks

  3. Time to resolution of diarrhea

    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 end of treatment.

    Time frame: Up to 10 weeks

Secondary outcomes

  1. Incidence of nephrotoxicity

    Nephrotoxicity is defined as: serum creatinine increase of more than 0.5 mg/dL if the baseline serum creatinine was ≤ 3 mg/dL or a rise of \> 1 mg/dL if the initial serum creatinine was \> 3 mg/dL; or 50% increase from baseline; or a drop in calculated creatinine clearance using Cockroft-Gault formula of ≥ 50% from baseline.

    Time frame: Until 10 weeks

  2. Incidence of hepatotoxicit

    Hepatotoxicity is defined as: AST or ALT 3 times upper limit of normal or if AST or ALT baseline is abnormal, AST or ALT increase of ≥ 3 times the baseline and adverse events/ reactions using the MedDRA SMQ (Standardised MedDRA Query) "Hepatic Disorders".

    Time frame: Up to 10 weeks

  3. Incidence of thrombocytopenia

    Thrombocytopenia is defined as: platelets \< 100 000/mm3 or \< 100 Giga/L

    Time frame: Up to 10 weeks

  4. Incidence of hearing and balance/vestibular disorders

    Hearing and balance/vestibular disorders are defined as: identified via PT terms using MedDRA SMQ for "hearing and vestibular disorders" (narrow) and additionally the PT "balance disorder".

    Time frame: Up to 10 weeks

  5. Additional renal endpoints: renal failure, dialysis and renal replacement therapy

    Time frame: Until 10 weeks

  6. Any untoward adverse events/reactions

    Time frame: Up to 10 weeks
