What this trial studies

This clinical trial aims to evaluate the safety and efficacy of Granulocyte-Colony Stimulating Factor (GCSF) in enhancing clinical outcomes for patients with biliary atresia. It involves a prospective, randomized, multi-institutional approach, where newly diagnosed biliary atresia patients are divided into two groups: those who have undergone the Kasai procedure and those who have not. Participants will receive GCSF or a placebo for three consecutive days following their diagnosis or surgery, and will be monitored for two years to assess the treatment's impact. The study is conducted under an FDA-approved Investigational New Drug application.

Who should consider this trial

Good fit: Ideal candidates include infants aged 14 to 180 days with a confirmed diagnosis of biliary atresia, either post-Kasai surgery or those who are not surgical candidates.

Not a fit: Patients with immediate access to liver transplantation or those with severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the clinical outcomes for infants diagnosed with biliary atresia.

How similar studies have performed: While this approach is novel in the context of biliary atresia, previous studies have shown promise in using GCSF for other conditions.
