Micafungin Prevention Study for Invasive Fungal Disease in Pediatric & Adolescent Patients Undergoing Autologous Hematopoietic Stem Cell Transplantation

Efficacy and Safety in Micafungin Sodium for Prophylaxis Against Invasive Fungal Disease During Neutropenia in Pediatric & Adolescent Patients Undergoing Autologous Hematopoietic Stem Cell Transplantation

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.

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 Autologous 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.

Inclusion Criteria:

1. Patients will receive autologous hematopoietic stem cell transplantation including 2nd autologous transplantation
2. Under 21 years old, pediatric, adolescent patients.

Exclusion Criteria:

1. Aspartate transaminase or alanine transaminase level > 5 times UNL
2. Bilirubin > 2.5 times UNL
