– First results from BEYOND Phase 2 trial of luspatercept in adult patients with non-transfusion-dependent beta-thalassemia presented at the European Hematology Association (EHA) 2021 Virtual Congress during Presidential Symposium –<\/i><\/p>\n
CAMBRIDGE, Mass.–(BUSINESS WIRE<\/a>)– \n\u201cWe were very pleased to highlight clinical updates from the PULSAR and SPECTRA Phase 2 trials of sotatercept reported at the annual ATS medical meeting and outline our plans for future long-term growth in rare pulmonary diseases at our Research & Development Day during the second quarter,\u201d said Habib Dable, President and Chief Executive Officer of Acceleron. \u201cBeyond our sotatercept clinical program in pulmonary arterial hypertension, most recently, we announced plans to expand the development of sotatercept into a Phase 2 trial in patients with Group 2 pulmonary hypertension and develop ACE-1334 in systemic sclerosis-associated interstitial lung disease. To date, our pulmonary pipeline has grown to include seven ongoing and planned clinical trials, showcasing our long-term commitment to becoming a global leader in rare pulmonary disease.\u201d\n<\/p>\n \nAdded Mr. Dable: \u201cWith respect to our hematology program, along with our commercial partner Bristol-Myers Squibb Company (Bristol Myers Squibb), we continue to be pleased with product uptake. Our joint commercial teams are presently focused on expanding the reach to appropriate patients earlier in their MDS journey\u2014where there is particular demand\u2014along with the optimal dose of REBLOZYL to maximize patient benefit and increased duration of treatment in this population to drive further growth this year and beyond. In June, we presented results from the BEYOND Phase 2 trial of luspatercept during the Presidential Symposium at EHA. The study achieved its primary endpoint of an increase in hemoglobin of at least 1 gram per deciliter in the luspatercept treated group compared to placebo for the treatment of anemia in adults with non-transfusion dependent beta-thalassemia, supporting the rationale for its potential development in additional patient groups.\u201d\n<\/p>\n Program Highlights<\/span><\/b><\/p>\n Pulmonary<\/i><\/b><\/p>\n Sotatercept: Pulmonary Hypertension ACE-1334: Systemic Sclerosis-associated Interstitial Lung Disease (SSc-ILD) Hematology<\/i><\/b><\/p>\n REBLOZYL (luspatercept-aamt)<\/span>: Corporate Highlights<\/span><\/b><\/p>\n Financial Results<\/span><\/b><\/p>\n Non-GAAP Financial Measures<\/span><\/b><\/p>\n \nAcceleron supplements its results of operations prepared in accordance with U.S. generally accepted accounting principles, or GAAP, with certain non-GAAP financial measures, including non-GAAP R&D expense, non-GAAP SG&A expense, adjusted net loss and adjusted net loss per share, that exclude stock-based compensation expense and depreciation and amortization expense. These results should not be viewed as a substitute for the Company\u2019s GAAP results and are provided as a complement to results provided in accordance with GAAP. Management believes these non-GAAP financial measures provide investors with additional insight into underlying trends of the Company’s ongoing business, and are important in comparing current results with prior period results. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures. In addition, other companies may report similarly titled non-GAAP measures, but calculate them differently, which reduces their usefulness as a comparative measure. In the reconciliation tables below, Acceleron presents these non-GAAP financial measures reconciled to their comparable GAAP financial measures.\n<\/p>\n Conference Call and Webcast<\/b><\/p>\n \nThe Company will host a webcast and conference call to discuss its second quarter 2021 financial results on August 5, 2021, at 5:00 p.m. EDT.\n<\/p>\n \nThe webcast will be accessible under “Events & Presentations” in the Investors & Media page of the Company\u2019s website at www.acceleronpharma.com<\/a>. To participate in the conference call, please dial 833-494-1483 (domestic) or 236-714-2620 (international) and reference code #5736809.\n<\/p>\n \nAn archived version of the webcast will be available for replay on the Company’s website for approximately one year.\n<\/p>\n About Acceleron<\/b><\/p>\n \nAcceleron is a biopharmaceutical company dedicated to the discovery, development, and commercialization of therapeutics to treat serious and rare diseases.

statements about the Company’s strategy, future plans and prospects, including statements regarding the development and commercialization of the Company’s compounds, the timeline for clinical development and regulatory approval of the Company’s compounds, the expected timing for reporting of data from ongoing clinical trials, the Company’s future cash position and the potential of REBLOZYL\u00ae (luspatercept-aamt) as a therapeutic drug. The words “anticipate,” “believe,” “could,” “estimate,” “expect,” “goal,” “intend,” “may,” “plan,” “potential,” “project,” “should,” “target,” “will,” “would,” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.\n<\/p>\n \nActual results could differ materially from those included in the forward-looking statements due to various factors, risks and uncertainties, including, but not limited to, that preclinical testing of the Company’s compounds and data from clinical trials may not be predictive of the results or success of other clinical trials, that regulatory approval of the Company\u2019s compounds in one indication or country may not be predictive of approval in another indication or country, that the development of the Company\u2019s compounds may take longer and\/or cost more than planned or accelerate faster than currently expected, that the Company or its collaboration partner, Bristol Myers Squibb Company (\u201cBMS\u201d), may be unable to successfully complete the clinical development of the Company\u2019s compounds, that the Company or BMS may be delayed in initiating, enrolling or completing any clinical trials, and that the Company\u2019s compounds may not receive regulatory approval or become commercially successful products. These and other risks and uncertainties are identified under the heading \u201cRisk Factors\u201d included in the Company\u2019s most recent Annual Report on Form 10-K and other filings that the Company has made and may make with the SEC in the future.\n<\/p>\n \nThe forward-looking statements contained in this press release are based on management’s current views, plans, estimates, assumptions, and projections with respect to future events, and the Company does not undertake and specifically disclaims any obligation to update any forward-looking statements.\n<\/p>\n View source version on businesswire.com: <\/span>https:\/\/www.businesswire.com\/news\/home\/20210805005947\/en\/<\/a><\/span><\/p>\n \nAcceleron Pharma Inc. \nMedia: KEYWORDS:<\/b> United States North America Massachusetts<\/p>\n INDUSTRY KEYWORDS:<\/b> Biotechnology Pharmaceutical Health<\/p>\n
