AbstractThe objective of this study was to evaluate the role of Ruxolitinib in steroid-refractory graft versus host disease. This retrospective descriptive study was conducted from January 2018 to December 2021. A total of 157 patients underwent allogeneic stem cell transplants during the study period. Of these, 20 patients having steroid-refractory GVHD treated with Ruxolitinib were selected for the study. The primary endpoint was the overall response rate to Ruxolitinib measured at 4 weeks and 24 weeks for acute and chronic GVHD, respectively. The secondary endpoints were overall survival and failure-free survival. Of these 20 patients, 7 (35%) had acute GVHD, and 13 (65%) had chronic GVHD. Of acute GVHD, 2 (10%) had grade II, 4 (20%) had grade III, and 1 (5%) had grade IV acute GVHD. Of 13 patients with chronic GVHD, 7 (35%) had moderate and 6 (30%) had severe chronic GVHD. In steroid-refractory acute GVHD, the overall response rate to Ruxolitinib was 85.7%, and in chronic GVHD, it was 84.6%. The failure-free survival was 80% and overall survival was 85%. Adverse events of any grade occurred in 16 (80%) patients with grade III/IV adverse events in 4 (20%) patients only. The study showed that Ruxolitinib is a safe and effective second-line therapy for acute and chronic steroid-refractory GVHD. Key Words: Ruxolitinib, GVHD, Allogeneic stem cell transplant.
