CAMBRIDGE, Mass., Jan. 08, 2024 (GLOBE NEWSWIRE) -- Agios Pharmaceuticals, Inc. (Nasdaq: AGIO), a leader in the field of cellular metabolism pioneering therapies for rare diseases, today announced its anticipated 2024 milestones and value-driving catalysts through 2026 that support the company’s mission to transform patient outcomes in rare diseases. Agios will present at the 42nd Annual J.P. Morgan Healthcare Conference on Wednesday, January 10, 2024, at 7:30 a.m. PT, and a live webcast will be available at investor.agios.com.

“We were pleased to announce positive topline data from the Phase 3 study of our lead PK activator, mitapivat, in non-transfusion-dependent alpha- or beta-thalassemia last week, a segment of the population with no currently approved therapeutic options in the U.S. We look forward to data readouts from four additional Phase 3 studies across our industry-leading PK activator franchise by the end of 2025,” said Brian Goff, chief executive officer at Agios. “This robust series of near-term catalysts positions Agios for potential launches of a first- and best-in-class therapy in thalassemia in 2025 and in sickle cell disease in 2026, and we look forward to maximizing the commercial opportunities ahead of us. Supported by our strong cash position, Agios is poised for significant progress in the next 12-24 months, and we look forward to the opportunity to deliver a novel oral treatment option for two additional hematologic diseases with high unmet need.”
