FDA Approves Reblozyl (luspatercept-aamt) to Treat Anemia in Adults with Lower-Risk Myelodysplastic Syndromes (MDS)


PRINCETON, N.J. & CAMBRIDGE, Mass.–(BUSINESS WIRE)–Apr. 3, 2020– Bristol Myers Squibb (NYSE: BMY) and Acceleron Pharma Inc. (NASDAQ: XLRN) today announced the U.S. Food and Drug Administration (FDA) has approved Reblozyl® (luspatercept-aamt), the first and only erythroid maturation agent (EMA), for the treatment of anemia failing an erythropoiesis stimulating agent and requiring 2 or more red blood cell (RBC) units over 8 weeks in adult patients with very low- to intermediate-risk myelodysplastic syndromes with ring sideroblasts (MDS-RS) or with myelodysplastic/myeloproliferative neoplasm with ring sideroblasts and thrombocytosis (MDS/MPN-RS-T). Reblozyl is not indicated for use as a substitute for RBC transfusions in patients who require immediate correction of anemia.1

“In clinical trials, Reblozyl has shown to have significant benefit for the treatment of anemia in patients with myelodysplastic syndromes who have ring sideroblasts,” said Guillermo Garcia-Manero, M.D., professor and chief of Section of Myelodysplastic Syndromes, Department of Leukemia, University of Texas MD Anderson Cancer Center. “Anemia is a serious consequence of MDS, requiring the majority of these patients to receive regular red blood cell transfusions, which can lead to additional complications, such as iron overload, transfusion site reactions and infections. In our current environment, we are reminded of the significant burden frequent blood transfusions can have on individuals and the healthcare system.”

“Today’s approval of Reblozyl is an important milestone for a majority of patients with myelodysplastic syndromes who have limited treatment options to address anemia associated with their disease. It also demonstrates our continued commitment to develop innovative products that improve the lives of patients living with serious diseases,” said Diane McDowell, M.D., vice president, Hematology Global Medical Affairs, Bristol Myers Squibb. “We are looking forward to making Reblozyl immediately available for this patient population.”

The FDA approval in MDS is based on results from the pivotal Phase 3 MEDALIST trial and marks the second indication for Reblozyl, which received its first approval in November 2019 for the treatment of anemia in adults with beta thalassemia who require regular RBC transfusions.1

“We’re excited that Reblozyl has been approved to help even more patients in need of treatment options,” said Habib Dable, President and Chief Executive Officer, Acceleron. “We are enormously grateful to the patients, families and caregivers who participated in and supported the Reblozyl clinical trials, and to the researchers at Acceleron and beyond who, more than a decade ago, began this important quest to address patients’ chronic anemias.”

The approval of Reblozyl was based on the findings of MEDALIST, a Phase 3, randomized, double blind, placebo-controlled, multi-center study evaluating the efficacy and safety of Reblozyl in patients with IPSS-R-defined very low-, low- and intermediate-risk non-del(5q) myelodysplastic syndromes (MDS) with ring sideroblasts. All patients were red blood cell (RBC) transfusion-dependent and were either refractory or intolerant to prior erythropoiesis-stimulating agent (ESA) therapy or were ESA naïve and unlikely to respond due to endogenous serum erythropoietin ≥200 U/L, and had no prior treatment with disease modifying agents.

In the trial, a significantly greater proportion of patients receiving Reblozyl achieved independence from RBC transfusions for at least eight weeks during the first 24 weeks of the trial compared with those receiving placebo, meeting the study’s primary endpoint.2 Additionally, a significantly greater proportion of patients receiving Reblozyl vs. placebo achieved at least 12 weeks of independence from transfusions within the first 24 and 48 weeks of the study.2

The majority of treatment-emergent adverse events (TEAEs) in the trial were Grade 1-2. Grade 3 or 4 treatment-emergent adverse events were reported in 42.5% of patients who received Reblozyl and 44.7% of patients who received placebo. The most common (>10%) all-grade adverse reactions included fatigue, musculoskeletal pain, dizziness, diarrhea, dyspnea, nausea, hypersensitivity reactions, headache, and upper respiratory tract infection.2

Results from MEDALIST were published in the New England Journal of Medicine in January 2020.

About MDS
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.2,3 People with MDS who develop anemia often require regular blood transfusions to increase the number of healthy red blood cells in circulation.4 Frequent transfusions are associated with an increased risk of iron overload, transfusion reactions and infections.5

About Reblozyl®
Reblozyl, the first and only erythroid maturation agent, promotes late-stage red blood cell maturation in animal models.1Bristol Myers Squibb and Acceleron are jointly developing Reblozyl as part of a global collaboration. Reblozyl is currently approved in the U.S. for the treatment of:

  • anemia in adult patients with beta thalassemia who require regular red blood cell transfusions, and
  • anemia failing an erythropoiesis stimulating agent and requiring 2 or more red blood cell units over 8 weeks in adult patients with very low- to intermediate-risk myelodysplastic syndromes with ring sideroblasts (MDS-RS) or with myelodysplastic/myeloproliferative neoplasm with ring sideroblasts and thrombocytosis (MDS/MPN-RS-T).

Reblozyl is not indicated for use as a substitute for red blood cell transfusions in patients who require immediate correction of anemia.

Bristol Myers Squibb: Advancing Cancer Research

At Bristol Myers Squibb, patients are at the center of everything we do. The goal of our cancer research is to increase quality, long-term survival and make cure a possibility. We harness our deep scientific experience, cutting-edge technologies and discovery platforms to discover, develop and deliver novel treatments for patients.

Building upon our transformative work and legacy in hematology and Immuno-Oncology that has changed survival expectations for many cancers, our researchers are advancing a deep and diverse pipeline across multiple modalities. In the field of immune cell therapy, this includes registrational chimeric antigen receptor (CAR) T-cell agents for numerous diseases, and a growing early-stage pipeline that expands cell and gene therapy targets, and technologies. We are developing cancer treatments directed at key biological pathways using our protein homeostasis platform, a research capability that has been the basis of our approved therapies for multiple myeloma and several promising compounds in early to mid-stage development. Our scientists are targeting different immune system pathways to address interactions between tumors, the microenvironment and the immune system to further expand upon the progress we have made and help more patients respond to treatment. Combining these approaches is key to delivering new options for the treatment of cancer and addressing the growing issue of resistance to immunotherapy. We source innovation internally, and in collaboration with academia, government, advocacy groups and biotechnology companies, to help make the promise of transformational medicines a reality for patients.
