FDA Approves Pyrukynd

FDA Approves Pyrukynd (mitapivat) as First Disease-Modifying Therapy for Hemolytic Anemia in Adults with Pyruvate Kinase Deficiency

CAMBRIDGE, Mass., Feb. 17, 2022 (GLOBE NEWSWIRE) -- Agios Pharmaceuticals, Inc. (NASDAQ: AGIO), a leader in the field of cellular metabolism pioneering therapies for genetically defined diseases, today announced that the U.S. Food and Drug Administration (FDA) has approved Pyrukynd® (mitapivat) in the U.S. for the treatment of hemolytic anemia in adults with pyruvate kinase (PK) deficiency, a rare, debilitating, lifelong hemolytic anemia. Pyrukynd® is a first-in-class, oral PK activator and the first approved disease-modifying therapy for this disease.

“The successful ACTIVATE and ACTIVATE-T studies demonstrate the impact of mitapivat in significantly improving hemolysis and anemia in PK deficiency,” said Hanny Al-Samkari, M.D., hematologist and clinical investigator at the Mass General Cancer Center and Harvard Medical School, and an investigator in these pivotal Phase 3 studies. “The FDA approval of mitapivat, a targeted agent and first disease-modifying medication in PK deficiency, is an encouraging step forward for these patients that addresses a significant unmet need.”

“Pyrukynd® is the first approved therapy for PK deficiency and marks an important milestone for these patients, who may face tremendous challenges and debilitating symptoms throughout the course of this lifelong disease,” said Rachael Grace, M.D., MMSc, pediatric hematologist, director of hematology clinical research at Boston Children’s Hospital and an investigator in the Phase 2 DRIVE PK and Phase 3 ACTIVATE studies. “Partnering with Agios and the PK deficiency community to improve understanding of the natural history of this rare disease and bring a new medicine to patients has been an honor, and I look forward to additional collaboration in the future.”

“I am so grateful that Pyrukynd® has been approved for PK deficiency. As both patient and caregiver, I spent the majority of my life feeling alone in this disease and never thought I would see a medicine approved,” said Kim Hall, who was diagnosed with PK deficiency in 1969 and is the mother of two adult daughters living with PK deficiency. All three women participated in the Phase 3 Pyrukynd® PK deficiency clinical program. “The experience of being part of the clinical trials has been impactful because of the connections we have built with other patients, healthcare providers and Agios colleagues who understand PK deficiency and are actively working to improve patients’ lives.”

“For more than a decade, we have been pioneering the science of PK activation in order to bring Pyrukynd® to people with PK deficiency and provide them with the first medication approved specifically to address this rare, debilitating blood disorder,” said Jackie Fouse, Ph.D., chief executive officer at Agios. “We remain committed to partnering with patients, caregivers, advocates and healthcare providers to ensure that the impact of Pyrukynd® is maximized through robust support, education and access programs. These connections have fueled today’s tremendous milestone for the PK deficiency community. Each of us at Agios is dedicated to making a difference for people with PK deficiency, as well as to expanding the reach of Pyrukynd® and our clinical and research programs to many more patients with genetically defined diseases around the world.”

Agios is offering a robust set of access programs aimed at reducing or eliminating patient out-of-pocket costs for Pyrukynd®, including a copay program that lowers copays to $0 for eligible commercially-insured patients and a Patient Assistance Program (PAP) that offers free prescriptions to eligible uninsured and underinsured patients. The myAgios® patient support services program provides a centralized resource to assist with support, access, education and adherence. Learn more and enroll at www.myagios.com.

Pyrukynd® is expected to be available in the U.S. approximately two weeks after approval. Pyrukynd® was reviewed by the FDA under Priority Review and was previously granted orphan drug designation. Pyrukynd® is also under review by the European Medicines Agency (EMA) as a potential treatment for adults with PK deficiency, and Agios expects a regulatory decision in the EU by the end of 2022.

Pyrukynd® Safety and Efficacy Data
The FDA granted approval to Pyrukynd® 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 was presented at the 2021 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; initial results from the extension study were recently presented at the 2021 American Society of Hematology (ASH) Annual Meeting and Exposition.

In mid-2022, the company expects to initiate two pivotal studies – ACTIVATE-kids and ACTIVATE-kidsT – in pediatric patients with PK deficiency who are not regularly transfused and who are regularly transfused, respectively. Agios also continues to advance its Phase 3 ENERGIZE and ENERGIZE-T studies in not regularly transfused and regularly transfused adults with thalassemia, as well as its Phase 2/3 RISE UP study in sickle cell disease.

About PK Deficiency
Pyruvate kinase (PK) deficiency is a rare, inherited disease that presents as chronic hemolytic anemia, which is the accelerated destruction of red blood cells. The inherited mutation in the PKLR gene can cause a deficit in energy within the red blood cell, as evidenced by lower PK enzyme activity, a decline in adenosine triphosphate (ATP) levels and a build-up of upstream metabolites, including 2,3-DPG (2,3-diphosphoglycerate).

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.

myAgios® Patient Support Services
The myAgios® patient support services program is a centralized platform for people living with PK deficiency and their caregivers. After enrolling in the program, patients and caregivers are connected with a dedicated Patient Support Manager (PSM) with a clinical background to provide tailored support, educational resources, access and benefits investigation services, financial assistance programs, prescription fulfillment and opportunities to connect with other patients and caregivers in the community.

About Pyrukynd® (mitapivat)
Pyrukynd is a pyruvate kinase activator indicated for the treatment of hemolytic anemia in adults with pyruvate kinase (PK) deficiency.

IMPORTANT SAFETY INFORMATION
Acute Hemolysis: Acute hemolysis with subsequent anemia has been observed following abrupt interruption or discontinuation of Pyrukynd in a dose-ranging study. Avoid abruptly discontinuing Pyrukynd. Gradually taper the dose of Pyrukynd to discontinue treatment if possible. When discontinuing treatment, monitor patients for signs of acute hemolysis and anemia including jaundice, scleral icterus, dark urine, dizziness, confusion, fatigue, or shortness of breath.

Adverse Reactions: Serious adverse reactions occurred in 10% of patients receiving Pyrukynd in the ACTIVATE trial, including atrial fibrillation, gastroenteritis, rib fracture, and musculoskeletal pain, each of which occurred in 1 patient. In the ACTIVATE trial, the most common adverse reactions including laboratory abnormalities (≥10%) in patients with PK deficiency were estrone decreased (males), increased urate, back pain, estradiol decreased (males), and arthralgia.

Drug Interactions:

Hepatic Impairment: Avoid use of Pyrukynd in patients with moderate and severe hepatic impairment.
