MT2019-37: A Randomized, Double-Blind, Placebo-Controlled Multicenter Phase III Trial of Alpha 1 - Antitrypsin (AAT) Combined with Corticosteroids vs Corticosteroids Alone for the Treatment of High Risk Acute Graft-versus-Host Disease (GVHD) Following Allogeneic Hematopoietic Stem Cell Transplant (CTN 1705)


This study is a phase III, multicenter, double-blinded, randomized, placebo-controlled trial designed to compare AAT and corticosteroids (CS) to placebo and CS as first line therapy for patients with high-risk acute GVHD. The primary objective of this trial is to compare the rate of complete response (CR) and partial response (PR) on Day 28 post-randomization between AAT and CS versus placebo to match (PTM) and CS in patients with high-risk acute GVHD.
