Recommendation for approval based on results from pivotal Phase 3 MEDALIST and BELIEVE studies

PRINCETON, NJ & CAMBRIDGE, MA, USA I April 30, 2020 IBristol Myers Squibb (NYSE: BMY) and Acceleron Pharma Inc. (NASDAQ: XLRN) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency has issued a positive opinion, recommending the approval of Reblozyl (luspatercept) for the treatment of:

This CHMP recommendation will now be reviewed by the European Commission (EC), which has the authority to approve medicines for the European Union (EU). If approved, Reblozyl would be the first erythroid maturation agent approved in the EU, representing a new class of therapy for eligible patients. The safety and efficacy results provided in the application are from the pivotal Phase 3 MEDALIST and BELIEVE studies, evaluating the ability of Reblozyl to effectively address anemia associated with MDS and beta thalassemia, respectively.

"Patients with myelodysplastic syndromes who experience anemia have limited treatment options, and some have been shown to not respond to available erythropoietin-based therapies," said Uwe Platzbecker, M.D., Head of Clinic and Policlinic for Hematology and Cell Therapy, Leipzig University Hospital and lead investigator of the MEDALIST study. If approved, the introduction of a new class of therapy in Reblozyl could provide a promising option to help relieve patients from the burden of regular transfusions to manage their disease.

Todays positive CHMP opinion of Reblozyl is an important milestone for adult beta thalassemia patients in the EU who have limited treatment options to address anemia, a serious consequence of the disease, said Maria Domenica Cappellini, M.D., Professor of Medicine, University of Milan, Fondazione IRCCS Ca Granda and lead investigator of the BELIEVE study. Reblozyl has the potential to significantly decrease the number of red blood cell transfusions patients need.

This decision by the CHMP is an important step towards making this first-in-class therapy an option for eligible patients with anemia due to beta thalassemia or myelodysplastic syndromes, said Diane McDowell, M.D., vice president, Hematology Global Medical Affairs, Bristol Myers Squibb. We, and our partners at Acceleron, look forward to the opportunity to make this treatment option available in the EU and are extremely appreciative of the patients, families and individuals who continue to help us progress important research in a range of serious diseases.

About MEDALIST

MEDALIST is a Phase 3, randomized, double-blind, placebo-controlled, multi-center study evaluating the safety and efficacy of luspatercept plus best supportive care (BSC) versus placebo plus BSC in adults with IPSS-R-defined very low-, low- or intermediate-risk non-del(5q) myelodysplastic syndromes (MDS). 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 nave and unlikely to respond due to endogenous serum erythropoietin levels of 200 U/L, and had no prior treatment with disease modifying agents. Results of the MEDALIST trial were first presented during the Plenary Session of the 2018 American Society of Hematology (ASH) Annual Meeting and were selected for the Best of ASH. The New England Journal of Medicine published the MEDALIST trial results in January 2020.

About MDS

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. People with MDS who develop anemia often require regular blood transfusions to increase the number of healthy red blood cells in circulation. Frequent transfusions are associated with an increased risk of iron overload, transfusion reactions and infections. There are approximately 50,000 patients with MDS in the EU5 countries.

About BELIEVE

BELIEVE is a Phase 3, randomized, double-blind, placebo-controlled multi-center study comparing luspatercept plus BSC versus placebo plus BSC in adults who require regular RBC transfusions (6-20 RBC units per 24 weeks with no transfusion-free period greater than 35 days during that period) due to beta thalassemia. Results of the BELIEVE trial were first presented at the 2018 ASH Annual Meeting and selected for the Best of ASH. The New England Journal of Medicine published the BELIEVE trial results in March 2020.

About Beta Thalassemia

Beta thalassemia is an inherited blood disorder caused by a genetic defect in hemoglobin. The disease is associated with ineffective erythropoiesis, which results in the production of fewer and less healthy RBCs, often leading to severe anemia a condition that can be debilitating and can lead to more severe complications for patients as well as other serious health issues. Treatment options for anemia associated with beta thalassemia are limited, consisting mainly of frequent RBC transfusions that have the potential to contribute to iron overload, which can cause serious complications such as organ damage. Across the United States, Germany, France, Italy, Spain and the United Kingdom, there are approximately 17,000 patients with beta thalassemia.

About Reblozyl

Reblozyl (luspatercept-aamt), a first-in-class erythroid maturation agent, promotes late-stage red blood cell maturation in animal models. Bristol 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:

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 patients quality of life, 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.
