GCSF Adjunct Therapy for Biliary Atresia

Summary

The Investigators propose to test the hypothesis that GCSF therapy enhances the clinical outcome of Kasai operated Biliary Atresia (BA) patients. In this study, Investigators will conduct a dose determination for GCSF use in post Kasai subjects to support a future phase 2 efficacy study. The first 3 post Kasai BA subjects with liver biopsy-confirmed BA will be given 5 ug/kg/d of GCSF in 3 daily subcutaneous doses starting on post Kasai day 3. A second group of 3 subjects will be assigned to the 10 ug/Kg/d dose after the 5ug/kg/d dose has been proven to be safe. The levels of circulating hematopoietic stem cells and a 1-month safety profile will be analyzed.
