CAMBRIDGE, Mass.--(BUSINESS WIRE)--Nov 6, 2019--
Acceleron Pharma Inc. (NASDAQ:XLRN), a leading biopharmaceutical company in the discovery and development of TGF-beta superfamily therapeutics to treat serious and rare diseases, today announced that data from six clinical abstracts on luspatercept will be presented at the 61st American Society of Hematology (ASH) Annual Meeting & Exposition in Orlando, Florida, on December 7-10, 2019. Luspatercept is being developed as part of a global collaboration between Acceleron and Celgene Corporation.
“It’s a privilege to return to the world’s largest hematology meeting to share updated results from the Phase 3 trials of luspatercept in patients with myelodysplastic syndromes and beta-thalassemia,” said Habib Dable, President and Chief Executive Officer of Acceleron. “With the presentations of both trials having garnered ‘Best of ASH’ honors in 2018, we’re thrilled to report that luspatercept has continued to demonstrate durable clinical benefit in both patient populations in the ongoing open-label studies. Moreover, interim Phase 2 data show clinically significant activity from luspatercept treatment in patients with myelofibrosis-associated anemia, further validating our confidence in luspatercept’s potential as a therapy for a variety of chronic anemias of high unmet need.”
Oral Presentation, Monday, December 9, 4:30 p.m. EST
Session 637. Myelodysplastic Syndromes – Clinical Studies: Lower-Risk MDS and CMML
Title: Assessment of Longer-Term Efficacy and Safety in the Phase 3, Randomized, Double-Blind, Placebo-Controlled MEDALIST Trial of Luspatercept to Treat Anemia in Patients (Pts) with Revised International Prognostic Scoring System (IPSS-R) Very Low-, Low-, or Intermediate-Risk Myelodysplastic Syndromes (MDS) with Ring Sideroblasts (RS) Who Require Red Blood Cell (RBC) Transfusions
Presenter: Pierre Fenaux
Clinical benefit, defined as a patient achieving red blood cell transfusion independence (RBC-TI) ≥ 8 weeks and/or modified hematologic improvement erythroid (HI-E) response per International Working Group 2006 criteria, was assessed, along with total duration of clinical benefit (time from achieving clinical benefit to discontinuation due to loss of benefit, adverse events [AEs], or other reasons).
Summary: Data in the abstract include MEDALIST Phase 3 trial results as of the January 7, 2019 cutoff date.
Poster Presentation, Monday, December 9, 6:00 p.m. EST
Session 112. Thalassemia and Globin Gene Regulation: Poster III
Title: Evaluating Luspatercept Responders in the Phase 3, Randomized, Double-Blind, Placebo-Controlled BELIEVE Trial of Luspatercept in Adult Beta-Thalassemia Patients (Pts) Who Require Regular Red Blood Cell (RBC) Transfusions
Presenter: Vip Viprakasit
Achievement and number of response episodes (defined as ≥ 33% reduction in RBC transfusion from baseline over any consecutive 24 weeks) were assessed at a median follow-up of 64.1 weeks. Duration of clinical benefit, defined as the time of first response (≥ 33% reduction in RBC transfusion over any 24 weeks) to discontinuation due to any cause at that episode, was also assessed.
Data in the abstract include results as of the May 11, 2018 cutoff date.
Oral Presentation,Monday, December 9, 7:00 a.m. EST
Session 634. Myeloproliferative Syndromes: Clinical: Emerging and Novel Targeted Therapies
Title: A Phase 2 Study of Luspatercept in Patients with Myelofibrosis-Associated Anemia
Presenter: Aaron T Gerds
Patients with myelofibrosis (MF) receiving a stable dose of ruxolitinib in combination with luspatercept treatment:
Patients with MF receiving luspatercept without concomitant treatment with ruxolitinib:
Four of 74 (5%) patients had grade 3–4 treatment-related adverse events (AEs). Treatment-related AEs occurring in ≥ 3% of patients were hypertension (11%), bone pain (8%), and diarrhea (4%). Seven (9%) patients had ≥ 1 AE resulting in treatment discontinuation.
Data in the abstract include interim results of the ongoing open-label, phase 2 trial evaluating luspatercept in patients with MF and anemia as of the data cutoff date of May 10, 2019.
