-- Significant scientific and clinical presence, including 10 presentations, underscores breadth and depth of SM leadership --
-- Blueprint Medicines to host investor conference call and webcast on Monday, February 27, 2023 --
CAMBRIDGE, Mass., Feb. 3, 2023 /PRNewswire/ -- Blueprint Medicines Corporation (NASDAQ: BPMC) today announced plans to present detailed results from the registrational PIONEER trial of AYVAKIT® (avapritinib) in indolent systemic mastocytosis (SM) at the 2023 American Academy of Allergy, Asthma and Immunology (AAAAI) Annual Meeting, February 24 to 27 in San Antonio. PIONEER data will be featured in two oral platform presentations on Sunday, February 26. One presentation will detail the statistically significant and clinically meaningful results AYVAKIT achieved across the primary and all key secondary endpoints in PIONEER, and a second late-breaking presentation will focus on the impact of AYVAKIT on skin signs and symptoms. An additional PIONEER poster presentation will feature data across a broad set of well-established quality-of-life measures.
Blueprint Medicines will share data across 10 presentations, further demonstrating the company's long-standing scientific leadership position and commitment to SM. Three presentations will focus on PIONEER results while the others will characterize the burden of disease and showcase new approaches to accelerate diagnostic rates, such as by collaborating with medical centers and community networks to generate novel testing algorithms.
"The breadth of data we are presenting at AAAAI reflects our ongoing partnership with the global systemic mastocytosis community, including clinicians and patient advocacy groups, to improve diagnosis, treatment and care, with the shared goal of transforming outcomes for patients living with this disease," said Becker Hewes, M.D., Chief Medical Officer at Blueprint Medicines. "PIONEER is the largest randomized controlled trial ever conducted in indolent SM, and we look forward to reporting study results on the significant clinical impact of AYVAKIT across measures of mast cell burden, symptoms and quality of life. AYVAKIT was designed to target the primary underlying driver of SM, and the totality of data from PIONEER highlights the treatment's potential to modify the disease and set a new standard of care, benefiting a broad range of patients with indolent SM."
Last month, Blueprint Medicines announced that the U.S. Food and Drug Administration (FDA) accepted the company's supplemental new drug application (sNDA) for AYVAKIT for the treatment of adults with indolent SM, and granted priority review with a May 22, 2023 action date under the Prescription Drug User Fee Act (PDUFA).
The accepted abstracts are listed below and are being published today in an online supplement to The Journal of Allergy and Clinical Immunology (JACI). To view the abstract supplement, go to https://www.jacionline.org/ or https://annualmeeting.aaaai.org.
