Reblozyl, the first erythroid maturation agent, met primary and key secondary endpoints in the first-line treatment of patients with very low/low/intermediate-risk myelodysplastic syndromes
PRINCETON, N.J.--(BUSINESS WIRE)-- Bristol Myers Squibb (NYSE: BMY) today announced the COMMANDS study, a Phase 3, open-label, randomized trial evaluating Reblozyl® (luspatercept-aamt), met its primary endpoint, demonstrating a highly statistically significant and clinically meaningful improvement in red blood cell transfusion independence (RBC-TI) with concurrent hemoglobin (Hb) increase in the first-line treatment of adult patients with very low-, low- or intermediate-risk myelodysplastic syndromes (MDS) who require RBC transfusions. This result was based on a pre-specified interim analysis conducted through an independent review committee. Safety results in the trial were consistent with the safety profile of Reblozyl previously demonstrated in the MEDALIST study (NCT02631070), and no new safety signals were reported.
“While advancements have been made in the treatment of anemia for patients with myelodysplastic syndromes, there remains a significant need for new and better first-line treatment options for patients with transfusion-dependent MDS,” said Noah Berkowitz, M.D., Ph.D., senior vice president, Hematology Development, Bristol Myers Squibb. “We are pleased with the positive results of the COMMANDS study and look forward to presenting these important data.”
Bristol Myers Squibb will complete a full evaluation of the COMMANDS data and work with investigators to present detailed results at an upcoming medical meeting, as well as discuss these results with health authorities. Bristol Myers Squibb thanks the patients and investigators who are participating in the COMMANDS clinical trial.
Reblozyl is being developed and commercialized through a global collaboration with Merck following Merck’s acquisition of Acceleron Pharma, Inc. in November 2021.
About COMMANDS
COMMANDS (NCT03682536) is a Phase 3, open-label, randomized study evaluating the efficacy and safety of Reblozyl versus epoetin alfa, for the treatment of anemia due to very low-, low- or intermediate-risk (IPSS-R) myelodysplastic syndrome (MDS) in patients who are red blood cell (RBC) transfusion dependent and were erythropoiesis stimulating agent (ESA) naïve.
The primary endpoint evaluated in this study is RBC transfusion independence (RBC-TI) for 12 weeks with a mean hemoglobin increase ≥1.5 g/dL. Key secondary endpoints include RBC-TI for 24 weeks, RBC-TI ≥12 weeks and erythroid response of at least 8 weeks during weeks 1-24 of the study.
About Myelodysplastic Syndromes
Myelodysplastic syndromes (MDS) are a group of closely related blood cancers characterized by ineffective production of healthy red blood cells, white blood cells and platelets, which can lead to anemia and frequent or severe infections.1,2 People with MDS who develop anemia often require regular blood transfusions to increase the number of healthy red blood cells in circulation.3 Frequent transfusions are associated with an increased risk of iron overload, transfusion reactions and infections.4
About Reblozyl® (luspatercept-aamt)
Reblozyl, a first-in-class therapeutic option, promotes late-stage red blood cell maturation in animal models.5 Reblozyl is being developed and commercialized through a global collaboration with Merck following Merck’s acquisition of Acceleron Pharma, Inc. in November 2021. Reblozyl is currently approved in the U.S. for the treatment of:
Reblozyl is not indicated for use as a substitute for red blood cell transfusions in patients who require immediate correction of anemia.
Important Safety Information
WARNINGS AND PRECAUTIONS
Thrombosis/Thromboembolism
In adult patients with beta thalassemia, thromboembolic events (TEE) were reported in 8/223 (3.6%) of REBLOZYL-treated patients. TEEs included deep vein thrombosis, pulmonary embolus, portal vein thrombosis, and ischemic stroke. Patients with known risk factors for thromboembolism (splenectomy or concomitant use of hormone replacement therapy) may be at further increased risk of thromboembolic conditions. Consider thromboprophylaxis in patients at increased risk of TEE. Monitor patients for signs and symptoms of thromboembolic events and institute treatment promptly.
Hypertension
Hypertension was reported in 10.7% (61/571) of REBLOZYL-treated patients. Across clinical studies, the incidence of Grade 3 to 4 hypertension ranged from 1.8% to 8.6%. In patients with beta thalassemia with normal baseline blood pressure, 13 (6.2%) patients developed systolic blood pressure (SBP) ≥130 mm Hg and 33 (16.6%) patients developed diastolic blood pressure (DBP) ≥80 mm Hg. In adult patients with MDS with normal baseline blood pressure, 26 (29.9%) patients developed SBP ≥130 mm Hg and 23 (16.4%) patients developed DBP ≥80 mm Hg. Monitor blood pressure prior to each administration. Manage new or exacerbations of preexisting hypertension using anti-hypertensive agents.
Extramedullary Hematopoietic Masses
In adult patients with transfusion-dependent beta thalassemia, EMH masses were observed in 3.2% of REBLOZYL-treated patients, with spinal cord compression symptoms due to EMH masses occurring in 1.9% of patients (BELIEVE and REBLOZYL long-term follow-up study).
In a study of adult patients with non-transfusion-dependent beta thalassemia, a higher incidence of EMH masses was observed in 6.3% of REBLOZYL-treated patients vs. 2% of placebo-treated patients in the double- blind phase of the study, with spinal cord compression due to EMH masses occurring in 1 patient with a prior history of EMH. REBLOZYL is not indicated for use in patients with non-transfusion-dependent beta thalassemia.
Possible risk factors for the development of EMH masses in patients with beta thalassemia include history of EMH masses, splenectomy, splenomegaly, hepatomegaly, or low baseline hemoglobin (
