Clinical Details

Official title: A Phase 3, Multicenter, Investigator-blind, Randomized, Parallel Group Study to Investigate the Safety and Efficacy of Fidaxomicin Oral Suspension or Tablets Taken q12h, and Vancomycin Oral Liquid or Capsules Taken q6h, for 10 Days in Pediatric Subjects With Clostridium Difficile-associated Diarrhea

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Investigator), Primary Purpose: Treatment

Primary outcome: Confirmed clinical response based on the assessment by the investigator

Secondary outcome:

Sustained clinical response at the end of study

Sustained clinical response 14 days after confirmation clinical response

Time to resolution of diarrhea

Recurrence of Clostridium difficile-associated Diarrhea (CDAD) during or at the end of the Follow-up period
