Chronic Graft Versus Host Disease cGVHD

Allogeneic transplant is potentially curative for hematological malignancies but its use is limited by the development of GVHD. Ruxolitinib now has FDA approval for treatment of chronic GVHD that has failed 1-2 prior lines of therapy based on a prior large, randomized phase III study. Given this evidence of safety and efficacy in the early refractory setting (after prednisone failure), Ruxolitinib represents an ideal agent to test in the primary therapy setting. Here investigators propose a phase 2 randomized study to compare Ruxolitinib to prednisone as a first-line therapy in the treatment of chronic GVHD.

The purpose of this study is to determine if vimseltinib is safe, tolerable and works effectively to treat adults with active moderate to severe cGVHD. Participants will be treated with vimseltinib in 28-day treatment cycles for approximately 2 years.
