PYRUVATE KINASE DEFICIENCY | Agios Submits New Drug Application To FDA For Mitapivat

Agios Pharmaceuticals, Inc. announced that it has submitted a New Drug Application (NDA) for Mitapivat to the U.S. Food and Drug Administration (FDA) for the treatment of adults with pyruvate kinase (PK) deficiency.

“With this NDA filing, we are poised to deliver the first potentially disease-modifying therapy for people with PK deficiency, a chronic, lifelong haemolytic anaemia characterized by serious complications affecting multiple organs,” said Chris Bowden, M.D., Chief Medical Officer at Agios.

“There are no approved therapies for PK deficiency, and the current management strategies of blood transfusions and splenectomy are associated with both short- and long-term risks, including iron overload, blood clots and increased risk for infections. PK deficiency can lead to chronic fatigue, haemolytic crisis, gallstones, splenomegaly, liver cirrhosis, pulmonary hypertension and osteoporosis, and the burden of disease can take a toll on patients’ ability to navigate work and other day-to-day activities, as well as on their mental health. We are looking forward to working with the FDA to provide a potential new treatment option for this community that may help address the significant unmet needs of PK deficiency patients.”

The NDA submission is based on results from two pivotal studies, ACTIVATE and ACTIVATE-T, conducted in not regularly transfused and regularly transfused adults with PK deficiency, respectively. A full analysis of these data – including patient-reported outcomes (PRO) – was recently presented at the European Hematology Association (EHA) Virtual Congress. An extension study for adults with PK deficiency previously enrolled in ACTIVATE or ACTIVATE-T is ongoing and designed to evaluate the long-term safety, tolerability, and efficacy of treatment with Mitapivat. The company remains on track to submit a marketing authorization application (MAA) in the EU in mid-2021 for Mitapivat in adults with PK deficiency.

Mitapivat is not approved for use by any regulatory authority.

PK deficiency is associated with serious complications, including gallstones, pulmonary hypertension, extramedullary hematopoiesis, osteoporosis, and iron overload and its sequelae, which can occur regardless of the degree of anemia or transfusion burden. PK deficiency can also cause quality of life problems, including challenges with work and school activities, social life, and emotional health. Current management strategies for PK deficiency, including red blood cell transfusions and splenectomy, are associated with both short- and long-term risks. There are no currently approved therapies for PK deficiency.
