A Phase 2b, Double-Blind, Three Arm, Randomized, Placebo Controlled Trial With Restricted Response Adaptive Randomization Testing the Efficacy and Safety of High Dose Methylprednisolone or Equine Anti-Thymocyte Globulin as Treatment for Acute Liver Failure in Pediatric Patients
National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)
Summary
TReatment for ImmUne Mediated PathopHysiology (TRIUMPH) is a multi-center, three arm, randomized, controlled trial of immunosuppressive therapy for children with acute liver failure. The study will determine if suppressing inflammatory responses with either corticosteroids or equine anti-thymocyte globulin therapy improves survival for children with this rare, life-threatening condition.
Description
Pediatric Acute Liver Failure (PALF) is a rare, devastating condition that affects an estimated 250 children per year in North America, causing death in approximately 15% and the need for liver transplantation in an additional 20-30%. In the majority of cases, a specific cause of the liver injury is never determined. Recent research supports the theory that many of these patients have liver injury related to a hyperinflammatory immune response to everyday infections or environmental exposures. There is strong evidence to show that equine anti-thymocyte globulin and methylprednisolone slow the…

Interventions
- DrugHigh-dose methylprednisolone
Subjects in the high-dose methylprednisolone arm will receive an initial dose of methylprednisolone IV 10 mg/kg/day for 3 days and 5 mg/kg/day on Day 4. Normal saline will be used as placebo pre-medications and infusions given at the same volume and duration as the eATG infusions.
- DrugEquine anti-thymocyte globulin
Subjects will receive eATG IV 40 mg/kg/day on Days 1- 4. Day 1 eATG infusion is run over 8 hours and Day 2-4 infusions are run over 4 hours.
- DrugPrednisolone
Subjects will receive prednisolone 1 mg/kg on Days 5-13 followed by a gradual taper with discontinuation at 42 Days as indicated below. Days 5 - 13 Prednisolone PO 1 mg/kg/day (max 50 mg/day) Days 14- 20 Prednisolone PO 0.5 mg/kg/day (max 25 mg/day) Days 21 - 27 Prednisolone PO 0.3 mg/kg/day (max 15 mg/day) Days 28 - 34 Prednisolone PO 0.1 mg/kg/day (max 5 mg/day) Days 35 - 41 Prednisolone PO 0.1 mg/kg every OTHER day (max 5 mg every other day) Day 42 Discontinue
- DrugPlacebo for prednisolone
Subjects will receive 1 mg/kg/day of oral placebo for prednisolone on days 5-13 followed by a gradual taper to discontinuation at 42 days as indicated below. Subjects receiving oral placebo will be given a solution that closely resembles the treatment drug. Days 5 - 13 Placebo for Prednisolone PO 1 mg/kg/day (max 50 mg/day) Days 14- 20 Placebo for Prednisolone PO 0.5 mg/kg/day (max 25 mg/day) Days 21 - 27 Placebo for Prednisolone PO 0.3 mg/kg/day (max 15 mg/day) Days 28 - 34 Placebo for Prednisolone PO 0.1 mg/kg/day (max 5 mg/day) Days 35 - 41 Placebo for Prednisolone PO 0.1 mg/kg every OTHER day (max 5 mg every other day) Day 42 Discontinue
