The purpose of this study is to evaluate absence of proven, probable, possible, suspected invasive fungal disease (IFDs) through the end of prophylaxis therapy and during 4 weeks after stopping of micafungin prophylaxis after allogeneic hematopoietic stem cell transplantation in pediatric and adolescent neutropenia patients. Patients will receive micafungin until the earliest of the following: 1) neutrophil engraftment; 2) development of proven, provable, possible or suspected invasive fungal disease; 3) development of unacceptable drug toxicity; 4) withdrawal from study participation or discontinuation of study treatment. Safety profile of micafungin is also evaluated.
This study is to evaluate safety and prophylaxis effect of micafungin after hematopoietic stem cell transplantation. Micafungin is administered until confirmation of neutrophil engraftment or treatment failure.
