The Investigators propose to test the hypothesis that GCSF enhances the clinical outcome of biliary atresia in a multi-institutional Phase 2 trial to prospectively evaluate the safety and efficacy of GCSF in each of the 2 groups of newly diagnosed BA patients: KBA (i.e., Kasai-operated) or NoK (i.e., patients who did not undergo Kasai surgery). Subjects who participate in the trial will be followed for 2 years.


This is a prospective, randomized, multi-institutional trial in KBA and NoK subjects to be conducted under a Food and Drug Administration approved Investigational New Drug application.

The KBA group is composed of just operated Kasai patients with intraoperative liver biopsy-confirmed BA. Their clinical characteristics have been described in the previously completed Phase 1 study under CR00005169 (ie. inclusion and exclusion criteria as described below)

The NoK group will be composed of newly diagnosed BA patients, including the following:

  • surgical patients in whom the Kasai was not performed for intraoperative technical reasons or due to advanced liver disease, who also have no option for rescue liver transplantation.
  • Unoperated patients whose family refuses surgery or who are not operative candidates

Having met the same inclusion and exclusion criteria as the Kasai KBS group,

  • eligible KBA subjects will be randomized to GCSF vs. no-GCSF at the 10 ug/kg/d dose to be given subcutaneously for 3 consecutive daily doses on the third day following the Kasai procedure.
  • eligible NoK subjects will be randomized to GCSF vs. no-GCSF at the 10 ug/kg/d dose to be given subcutaneously for 3 consecutive daily doses on the third day following diagnostic liver biopsy.
