What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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) | 2 days after 7-14 days treatment | 
| Recurrence rate | Recurrence is defined as reappearance of diarrhea during the 8-week follow-up period. | Up to 10 weeks | 
| 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. | Up to 10 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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. | Until 10 weeks | 
| 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. | Up to 10 weeks | 
| Incidence of thrombocytopenia | Thrombocytopenia is defined as: platelets < 100 000/mm3 or < 100 Giga/L | Up to 10 weeks | 
| 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. | Up to 10 weeks | 
| Additional renal endpoints: renal failure, dialysis and renal replacement therapy |  | Until 10 weeks | 
| Any untoward adverse events/reactions |  | Up to 10 weeks |
