Consistent with previously announced proof-of-concept data, the study met its primary endpoint, with 16 of the 20 patients (80%) achieving a hemoglobin increase of ≥1.0 g/dL from baseline at one or more assessments during Weeks 4-12. Additionally, a sustained hemoglobin response and improvements in hemolysis and ineffective erythropoiesis were observed in both α- or β-thalassemia patients treated with mitapivat. Mitapivat was well tolerated, and the safety profile was consistent with previous studies. Mitapivat is a first-in-class, investigational, oral, small molecule allosteric activator of wild-type and a variety of mutated pyruvate kinase R (PKR) enzymes.
“These data continue to validate the potential of PK activation as an entirely new mechanism for treating thalassemia, a disease for which there have been few medical advancements. In particular, we are excited to see data generated, for the first time, in α-thalassemia, demonstrating an increase in hemoglobin from baseline in all five patients in this subgroup,” said Kevin Kuo, M.D., hematologist at University Health Network, University of Toronto, and an investigator in the study. “The impressive results reported today underscore the potential of mitapivat to meaningfully improve hallmarks of this disease, including hemolysis and ineffective erythropoiesis.”
Mitapivat Phase 2 Proof-of-concept StudyThe open-label Phase 2 study evaluated the efficacy, safety, pharmacokinetics and pharmacodynamics of mitapivat treatment in adults with either non-transfusion-dependent α- or β-thalassemia who have a baseline hemoglobin (Hb) concentration of ≤10 g/dL. The trial enrolled 20 patients. All patients were treated with an initial dose of mitapivat 50 mg twice daily followed by a dose-level increase to 100 mg twice daily at the Week 6 visit based on safety evaluations and hemoglobin concentrations. Following the completion of the 24-week core period, patients had the opportunity to enroll in an optional 10-year extension period which will evaluate long-term efficacy and safety of mitapivat in this population.
Efficacy Data
Safety DataThe majority of adverse events (AEs) observed were consistent with previously published data for mitapivat in healthy volunteers and patients with pyruvate kinase (PK) deficiency.
“We are pleased to present data from our Phase 2 trial of mitapivat, which is the first clinical study of a PK activator in thalassemia and the first drug trial in α-thalassemia, and represents a potentially innovative therapeutic approach for these patients who are in need of new treatment options,” said Chris Bowden, chief medical officer at Agios. “Our focus now is to advance the development of mitapivat in thalassemia as quickly and efficiently as possible, with the initiation of two Phase 3 studies of mitapivat, ENERGIZE and ENERGIZE-T, in not regularly transfused and regularly transfused adults with thalassemia. Additionally, we look forward to further advancing mitapivat as a potential treatment for other underserved patients with hemolytic anemias, including individuals with pyruvate kinase deficiency, where our U.S. and EU regulatory filing plans are on track, and sickle cell disease, where our pivotal development program is on track to initiate by year-end.”
Oral Presentation Information
Title: Results from a Phase 2, open-label, multicenter study of the oral pyruvate kinase activator mitapivat in adults with non-transfusion dependent alpha- or beta-thalassemiaLive Q&A Session Date and Time: Tuesday, June 15, 2021, at 8:45 p.m. CEST / 2:45 p.m. ETOral Abstract Session: Changing the scene on thalassemiasAbstract: S267Presenter: Kevin H. M. Kuo, M.D., Division of Hematology, University of Toronto, Toronto, Canada
Mitapivat Clinical DevelopmentIn addition to the Phase 2 extension study of mitapivat in adults with non-transfusion-dependent α- and β-thalassemia, Agios is initiating two Phase 3 studies of mitapivat in adults with thalassemia in the second half of 2021. They are:
In addition to its Phase 2 study of mitapivat in adults with non-transfusion-dependent α- or β-thalassemia, Agios has completed two global, pivotal trials in adults with pyruvate kinase (PK) deficiency. Final data from these studies will be presented in an oral session at the EHA Virtual Congress. They are:
ACTIVATE and ACTIVATE-T are intended to support global regulatory filings for mitapivat in adults with PK deficiency in the U.S. in the second quarter of 2021 and in the EU in mid-2021. Agios also is conducting an extension study for adults with PK deficiency previously enrolled in ACTIVATE or ACTIVATE-T, which is designed to evaluate the long-term safety, tolerability and efficacy of treatment with mitapivat.
In addition, mitapivat is being evaluated as a potential treatment for sickle cell disease under a Cooperative Research and Development Agreement (CRADA) with the U.S. National Institutes of Health. Mitapivat has been shown to decrease 2,3-diphosphoglycerate (2,3-DPG) and increase adenosine triphosphate (ATP), and through this mechanism, it may reduce hemoglobin S polymerization and red blood cell sickling. Preliminary clinical data establishing proof-of-concept for mitapivat in sickle cell disease were disclosed in June 2020, and updated data were presented at the American Society of Hematology (ASH) Annual Meeting in December 2020. Agios is initiating its pivotal Phase 2/3 study in sickle cell disease by year-end 2021.
Mitapivat has been granted orphan drug designation for the treatment of PK deficiency by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency. Additionally, mitapivat has received orphan drug designation from the FDA for the treatment of thalassemia and sickle cell disease.
Mitapivat is not approved for use by any regulatory authority.
CONFERENCE CALL INFORMATION
