Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In this study, the investigators conduct a phase II trial of a potential new medical therapy for BA: pentoxifylline (PTX). PTX is a methylxanthine derivative closely related to caffeine that has been used safely in infants with other diseases such as sepsis. In adults, PTX has been shown to have a number of properties beneficial to the liver, including preventing liver fibrosis, improving liver regeneration, and reducing cirrhosis-related complications.
The trial's objective is to determine whether PTX has sufficient biological activity against BA to warrant further study. PTX will be administered orally for 90 days as an adjunct to standard therapy (i.e. KP if appropriate). The primary outcome will measure the change in serum conjugated bilirubin levels after 90 days. Secondary outcomes include changes in body weight, serum markers, liver imaging, and time to liver transplant in infants with BA.

Pentoxifylline
All newly-diagnosed biliary atresia patients fulfilling the study's inclusion criteria will receive oral pentoxifylline, 20 mg/kg/day divided in three doses for a total of 90 days.
The hospital pharmacy will create a 20 mg/ml oral pentoxifylline solution using 400 mg pentoxifylline tablets and established compounding recipes.
Pentoxifylline
20 mg/kg/day divided in 3 doses, given orally for 90 days
