CAMBRIDGE, Mass., June 15, 2024 (GLOBE NEWSWIRE) -- Agios Pharmaceuticals, Inc. (Nasdaq: AGIO), a leader in cellular metabolism and pyruvate kinase (PK) activation pioneering therapies for rare diseases, today presented detailed results from the global Phase 3 ENERGIZE study of mitapivat in adults with non-transfusion-dependent (NTD) alpha- or beta-thalassemia in a plenary session (abstract #S104) at the European Hematology Association 2024 (EHA2024) Hybrid Congress, which is being held June 13-16, 2024, in Madrid, Spain. In a related poster presentation (abstract #P1529), the company presented additional data from the ENERGIZE study highlighting clinically meaningful improvements in health-related quality of life measures and patient-reported outcomes among patients in the mitapivat arm compared to those in the placebo arm.
The ENERGIZE study achieved its primary endpoint, with mitapivat demonstrating a statistically significant increase in hemoglobin response rate compared to placebo. Statistical significance was also achieved for both key secondary endpoints associated with change from baseline in FACIT-Fatigue Score and hemoglobin concentration. These improvements were observed across all pre-specified subgroups.
“The data from the ENERGIZE study are compelling, with mitapivat-treated patients achieving meaningful improvements in non-transfusion-dependent thalassemia’s hallmark symptom of anemia as well as in key measures of how patients feel and function,” said Sarah Gheuens, M.D., Ph.D., chief medical officer and head of R&D at Agios. “Together with the recently announced positive results from the ENERGIZE-T study of mitapivat in adults with transfusion-dependent thalassemia, the detailed ENERGIZE results underscore mitapivat’s potential to become an important treatment option for all subtypes of thalassemia – alpha- and beta-thalassemia, transfusion-dependent and non-transfusion-dependent – with the convenience of a pill. We look forward to working with regulators as we anticipate filing for approval in the U.S. by the end of this year.”
“I am pleased to present the results of the ENERGIZE study to my esteemed colleagues and believe they will share my enthusiasm for the positive impact mitapivat may have for patients with non-transfusion-dependent alpha- or beta-thalassemia,” said Ali Taher, M.D., Ph.D., Professor of Medicine, Hematology & Oncology and Director – Naef K. Basile Cancer Institute, American University of Beirut Medical Center in Beirut, Lebanon; an investigator in the ENERGIZE study. “Globally, there are currently no approved oral treatments for non-transfusion-dependent thalassemia, which is characterized by anemia, ineffective erythropoiesis, hemolysis and iron overload and can cause severe complications, reduced quality of life and shortened lifespan. Based on the data collected in the ENERGIZE study, mitapivat has the potential to become a foundational treatment for non-transfusion-dependent thalassemia.”
“The ENERGIZE data presented at this congress show that non-transfusion-dependent alpha- or beta-thalassemia patients treated with mitapivat experienced clinically meaningful improvements in fatigue and walking capacity, as well as improvements in patient-reported outcomes across a range of disease symptoms,” said Kevin Kuo, M.D., MSc, FRCPC; Division of Hematology, University of Toronto in Ontario, Canada; an investigator in the ENERGIZE study. “There is a tremendous need for oral therapies that can improve how people with thalassemia feel and function and reduce the impact of the disease on their lives. Patients with alpha- or beta-thalassemia, regardless of transfusion status, frequently report negative effects on daily activities and physical functioning. On a number of domains of health-related quality of life, adults with non-transfusion-dependent thalassemia experience even greater symptom burden than their transfusion-dependent counterparts. I am excited about the potential of mitapivat to support quality of life improvements for these individuals.”
Agios also recently announced positive results from the Phase 3 ENERGIZE-T study of mitapivat in adults with transfusion-dependent alpha- or beta-thalassemia. The company intends to file for regulatory approval of mitapivat as a treatment for thalassemia by the end of 2024, incorporating all available data from both studies.
Results for the Phase 3 ENERGIZE study were as follows:
- A total of 194 patients were enrolled in the study, with 130 randomized to mitapivat 100 mg twice-daily (BID) and 64 randomized to matched placebo. 122 (93.8%) in the mitapivat arm and 62 (96.9%) in the placebo arm completed the 24-week double-blind period of the study.
- Baseline demographics and characteristics were balanced between mitapivat and placebo arms, and representative of a population of non-transfusion dependent thalassemia patients.
- The study met the primary endpoint of hemoglobin response. Hemoglobin response was defined as an increase of ≥1 g/dL in average hemoglobin concentrations from week 12 through week 24 compared with baseline.
- 42.3% (n=55/130) of patients in the mitapivat arm achieved a hemoglobin response, compared to 1.6% (n=1/64) of patients in the placebo arm (2-sided p
