简要总结
The objective of this study is to demonstrate the efficacy and safety of Fidaxomicin versus placebo for prophylaxis against Clostridium difficile-Associated Diarrhea (CDAD) in adult participants undergoing hematopoietic stem cell transplantation (HSCT). The primary hypothesis is that Fidaxomicin is superior to placebo in preventing CDAD in participants undergoing HSCT.
