CAMBRIDGE, Mass., Sept. 16, 2022 (GLOBE NEWSWIRE) -- Agios Pharmaceuticals, Inc. (NASDAQ: AGIO), a leader in the field of cellular metabolism pioneering therapies for rare and genetically defined diseases, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion on September 15, 2022, recommending the granting of a marketing authorization for PYRUKYND® (mitapivat) for the treatment of pyruvate kinase (PK) deficiency in adult patients. PK deficiency is a rare, debilitating, lifelong hemolytic anemia. PYRUKYND® is a first-in-class, oral PK activator that was recently approved by the U.S. Food and Drug Administration (FDA). If approved by the European Commission (EC), PYRUKYND® will be the first approved disease-modifying therapy for European patients with PK deficiency.

“The positive CHMP opinion for PYRUKYND® is a landmark event for European patients with PK deficiency, who currently have no disease-modifying treatment options,” said Eduard J. van Beers, M.D., Ph.D., hematologist and associate professor at University Medical Center Utrecht. “PK deficiency is characterized by severe symptoms and complications, regardless of transfusion status, and has a significant impact on patients’ quality of life. If approved, I look forward to having an oral medication available that has demonstrated clinically meaningful impact for patients with a range of PK deficiency symptoms and presentations.”

“Today’s positive CHMP opinion is an important step toward our goal of expanding PYRUKYND® access for adults with PK deficiency around the world,” said Sarah Gheuens, M.D., Ph.D., head of R&D and chief medical officer at Agios Pharmaceuticals. “In addition to this milestone, we remain focused on our global clinical development programs for PYRUKYND® in thalassemia, sickle cell disease and pediatric PK deficiency and look forward to expanding the impact of this medication to even more patients.”

PYRUKYND® was previously granted orphan drug designation by the EMA.

PYRUKYND® Safety and Efficacy Data
The positive CHMP opinion was based on results from two pivotal studies, ACTIVATE and ACTIVATE-T, conducted in not regularly transfused and regularly transfused adults with PK deficiency, respectively.

  • The Phase 3 ACTIVATE trial of mitapivat achieved its primary endpoint. PYRUKYND® demonstrated a statistically significant increase in hemoglobin in patients with PK deficiency who are not regularly transfused.

    • 40 percent (n=16) of patients randomized to PYRUKYND® achieved a hemoglobin response, compared to 0 patients randomized to placebo (2-sided p<0.0001).

    • Statistically significant improvements compared to placebo were also demonstrated for all pre-specified secondary endpoints, including markers of hemolysis and ineffective erythropoiesis.

  • The Phase 3 ACTIVATE-T trial of mitapivat achieved its primary endpoint. Mitapivat demonstrated a statistically significant and clinically meaningful reduction in transfusion burden for patients who are regularly transfused.

    • 37 percent (n=10) of patients achieved a transfusion reduction response, defined as a ≥33% reduction in transfusion burden in the 24-week fixed dose period compared with individual historical transfusion burden standardized to 24 weeks.

    • 22 percent (n=6) of patients were transfusion-free during the fixed-dose period.

  • The most common adverse reaction across both studies was insomnia (19.4%), and the most common laboratory abnormalities observed were oestrone decreased (males) (43.5%) and oestradiol decreased (males) (8.7%).
