CAMBRIDGE, Mass., Jan. 10, 2022 (GLOBE NEWSWIRE) -- Agios Pharmaceuticals, Inc. (NASDAQ: AGIO), a leader in the field of cellular metabolism pioneering therapies for genetically defined diseases, today announced its anticipated 2022 key milestones and priorities that will drive its transition to a commercial-stage genetically defined disease company and the expansion of its robust clinical and research portfolio. Agios will present at the virtual 40th Annual J.P. Morgan Healthcare Conference on Wednesday, January 12 at 7:30 a.m. ET, and a live webcast will be available at investor.agios.com.

“We are beginning an exciting and defining year for Agios as we prepare for our first genetically defined disease product launch, execute on five pivotal clinical trials, continue to expand our PK activation clinical portfolio and foster our innovative research engine,” said Jackie Fouse, Ph.D., chief executive officer of Agios. “We are already making strong progress with mitapivat being evaluated under FDA Priority Review in the U.S. as a potential treatment for adults with PK deficiency and executing our Phase 3 ENERGIZE and ENERGIZE-T studies in thalassemia and Phase 2/3 RISE UP study in sickle cell disease. In 2022, we expect to further drive our PK activation expansion strategy by initiating our pivotal trials in pediatric PK deficiency, completing enrollment in the Phase 2 portion of the RISE UP study and advancing our novel PK activator AG-946 in sickle cell disease and low to intermediate risk myelodysplastic syndrome. At Agios, we are fueled by connections – with patient communities, a world-class network of healthcare providers and researchers, and each other – and these collaborative partnerships will drive our key priorities and advance care for people with genetically defined diseases.”
