Phase 2
Completed
Conditions
Clostridium Difficile Infection
Interventions
Registration Number
NCT01222702
Lead Sponsor
Actelion
Brief Summary

Cadazolid is a new antibiotic developed for the treatment of Clostridiun difficile associated diarrhea (CDAD), also known as Clostridium Difficile Infection (CDI). The purpose of the study was to evaluate the efficacy and safety of different doses of cadazolid in order to find the dose of cadazolid to be used for further clinical development of the compound in subjects with CDAD.

Primary Outcome Measures
NameTimeMethod
Clinical cure rate at test-of-cureDay 13 or 24-72 hours after end of treatment

Percentages of subjects with clinical cure are calculated, with clinical cure being defined as resolution of diarrhea with no further Clostridium Difficile-associated diarrhea (CDAD) treatment required at test-of-cure (TOC) visit.

Resolution of diarrhea was defined as the occurrence of ≤ 2 semi-formed or formed stools during 24 h for at least 2 consecutive 24 h periods.

Secondary Outcome Measures
NameTimeMethod
Recurrence rateBetween Day 13 and Day 41 (within 4 weeks after end of treatment)

Percentages of subjects with recurrence are calculated, with recurrence being defined as the occurrence of diarrhea (\> 3 liquid or unformed stools within 24 h associated with positive C. difficile toxin A/B assay) within 4 weeks after EOT in subjects clinically cured (at test-of-cure).

Time to resolution of diarrheaFrom Day 1 up to Day 13 (or 24-72 hours after end of treatment)

Time to resolution of diarrhea was defined as the time (h) from the first intake of study treatment to the time (occurrence) of the first stool meeting the criteria for resolution of diarrhea up to test-of-cure.

Adverse events leading to premature discontinuation of study treatmentUp to Day 10

Number of patients in each group who discontinued the study treatment due to an adverse event

Incidence of treatment-emergent adverse eventsFrom Day 1 to Day 14

Percentage of subjects with any adverse events in each group from first study treatment intake up to 3 days after last study drug intake

Sustained cure rateBetween Day 13 and day 41 (within 4 weeks after end of treatment)

Percentages of subjects with sustained cure are calculated, with sustained cure being defined as clinical cure without CDAD recurrence up to the end of study
