Ruxolitinib Plus Etanercept vs Ruxolitinib for Steroid-Refractory Severe Acute GVHD

研究简介（原文）

This is a prospective, multicenter, randomized controlled trial designed to evaluate whether the combination of ruxolitinib and etanercept provides superior efficacy compared with ruxolitinib monotherapy in patients with severe corticosteroid-refractory acute graft-versus-host disease (SR-aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Acute graft-versus-host disease (aGVHD) is one of the most common and life-threatening complications following allo-HSCT. Although corticosteroids remain the standard first-line treatment, many patients do not respond adequately. For patients with severe steroid-refractory aGVHD, the prognosis is extremely poor, with high short-term mortality and very low long-term survival. Ruxolitinib, a JAK1/2 inhibitor, has been approved for the treatment of SR-aGVHD, but response rates remain suboptimal, particularly in patients with gastrointestinal involvement. Etanercept, a tumor necrosis factor-alpha (TNF-α) inhibitor, has shown activity in GVHD by targeting inflammatory pathways. Previous observational studies from our center suggested that combining ruxolitinib with etanercept may improve response rates, especially in gastrointestinal and hepatic GVHD, without significantly increasing relapse risk. In this trial, approximately 122 patients with grade III-IV SR-aGVHD will be randomized 1:1 to receive either ruxolitinib alone or ruxolitinib plus etanercept. The primary endpoint is the overall response rate (ORR) at day 28. Secondary endpoints include durable response, best overall response, failure-free survival, overall survival, cumulative incidence of relapse, non-relapse mortality, incidence of chronic GVHD, and safety outcomes. This study seeks to provide new clinical evidence for an optimized treatment strategy for patients with severe SR-aGVHD, aiming to improve outcomes in this high-risk population.
