Chronic graft-versus-host disease (GVHD) is a serious complication that can happen after receiving a stem cell transplant, which is when you receive stem cells from donated blood. GVHD occurs when the donor T cells, which are cells that help protect the body, think your healthy cells are foreign and attack them. Acute GVHD occurs within 100 days of your transplant, and chronic GVHD occurs after 100 days and can affect multiple organs in your body. Rezurock (belumosudil) is used for people with chronic GVHD.
In clinical studies, 75% of people taking Rezurock (belumosudil) had improvement in their GVHD. On average, an improvement was seen after taking Rezurock (belumosudil) for about 2 months, and the improvement lasted about 2 months.
No, Rezurock (belumosudil) is only for people who tried but didn't have success with two prior GVHD treatments, which is typically corticosteroids and immunosuppressants, like rituximab (Rituxan) or methotrexate.
