" Chronic graft-versus-host disease affects multiple organs and can profoundly impact patients' quality of life. This milestone for Rezurock® brings renewed hope to patients and families who've faced limited treatment options for too long. Making innovative therapies available to Quebec patients with severe symptoms represents not just progress, but a meaningful path forward for managing this challenging condition ."    

Chronic GVHD is a complication that can occur following allogeneic stem cell transplantation, resulting in significant morbidity and mortality.[3] In chronic GVHD, transplanted immune cells (graft) attack the patient's cells (host), leading to inflammation and fibrosis in multiple tissues, including skin, mouth, eye, joint, liver, lung, esophagus and gastrointestinal tract.^3-5

About Rezurock®
Rezurock® is an inhibitor of Rho-associated, coiled-coil containing protein kinase-2 (ROCK2) and ROCK1, with IC₅₀ values of approximately 100 nM and 3 μM, respectively. Belumosudil downregulated proinflammatory responses via modulation of CD4+ T-cell activity and STAT3/STAT5 phosphorylation in ex vivo or in vitro human T cell assays. Belumosudil also inhibited pro-fibrotic signaling in vitro. In vivo, Rezurock® demonstrated activity in animal models of chronic GVHD.¹
