To Compare the Efficacy of the Addition of Methotrexate (MTX) to Current Standard Acute Graft-versus-host Disease (GVHD) First-line Treatment With Corticosteroids

Summary

Phase III randomized double-blinded trial designed to compare the efficacy of the addition of MTX to current standard acute GVHD first-line treatment with corticosteroids. The protocol will use a novel endpoint for benchmarking interventions based on a composite primary endpoint of GVHD-free and corticosteroids-free survival. The primary endpoint of the trial will be the assessment of a composite endpoint of graft-versus-host disease-free and corticosteroids-free survival at 12 months after randomization

Detailed description

This is a phase III randomized, multicenter, double blinded controlled study. Patients who develop clinically meaningful acute GVHD and who meet all other entry criteria will be randomized 1:1 to receive either corticosteroids and placebo ("standard of care", control arm) or the combination of low-dose MTX with corticosteroids as first-line therapy for acute GVHD (MTX; "experimental arm"). The primary analysis of this hypothesis generation study is to estimate the composite endpoint of GVHD-free and corticosteroids-free survival at 12 months after randomization in both treatment arms. In fact, it is more and more established that such composite endpoint is a clinically very relevant one because it represents ideal recovery from allo-SCT (Stem Cell transplantation) (at 1 year after acute GVHD diagnosis) and a measure of cure without ongoing morbidity.

Conditions

• Stem Cell Transplant Complications

Interventions

Type	Name	Description
DRUG	Methotrexate	Methotrexate 5 mg/m2 will be given once week for 4 weeks, then 3 mg/m2 every two weeks for 12 weeks. Body surface area will be capped at 2 m2. Methotrexate will be given as an IV infusion over 15 minutes. All patients will received prednisone 2 mg/kg.day PO (or methylprednisolone 1.6 mg/Kg/day) for 3 days. For responding patients between day 4 and 28, the dose of prednisone must be at least 0.25 mg/kg/day prednisone (or 0.2 mg/kg/day methylprednisolone). All patients should receive a folinic acid supplementation 24 hours after each MTX/placebo administration. Lederfoldin 10 mg po or iv will be administered on days 2, 9, 16 and 23. Lederfoldin 10 mg po or iv will be administered on days 37, 51, 65, 79, 93 and 103.
DRUG	Placebo	Placebo 5 mg/m2 will be given once week for 4 weeks, then 3 mg/m2 every two weeks for 12 weeks. Body surface area will be capped at 2 m2. Placebo will be given as an IV infusion over 15 minutes. All patients will received prednisone 2 mg/kg.day PO (or methylprednisolone 1.6 mg/Kg/day) for 3 days. For responding patients between day 4 and 28, the dose of prednisone must be at least 0.25 mg/kg/day prednisone (or 0.2 mg/kg/day methylprednisolone). All patients should receive a folinic acid supplementation 24 hours after each MTX/placebo administration. Lederfoldin 10 mg po or iv will be administered on days 2, 9, 16 and 23. Lederfoldin 10 mg po or iv will be administered on days 37, 51, 65, 79, 93 and 103.
