Roxadustat Combined With Luspatercept Versus Luspatercept Monotherapy in the Treatment of Refractory MDS-RS

Summary

In a randomized controlled phase II/III clinical trial, 58% of patients with lower-risk MDS had at least a 50% reduction in red blood cell (RBC) transfusion units every 8 weeks after roxadustat treatment. In a randomized controlled phase III clinical trial, luspatercept significantly improved transfusion dependence in erythropoietin-stimulating agents (ESA)-refractory MDS-RS and improved hemoglobin response and quality of life, compared to placebo. This study aimed to evaluate the efficacy and safety of roxadustat combined with luspatercept versus luspatercept monotherapy in the treatment of refractory MDS-RS.
