A Randomized, Double-Blind, Placebo-Controlled, Multicenter Phase III Trial of Remestemcel-L-rknd Added to Ruxolitinib for Grade III-IV Steroid-Refractory Acute Graft-Versus-Host Disease

This study is a randomized, double-blind, placebo-controlled, multicenter Phase III trial to compare the efficacy and safety of remestemcel-L-rknd (remestemcel-L), ex-vivo cultured adult human mesenchymal stromal cells (MSC), combined with ruxolitinib vs. ruxolitinib combined with placebo as second-line therapy in adult patients with Grade III-IV steroid-refractory acute graft-versus-host disease (SR-aGVHD).
