(Nasdaq: AGIO), a commercial-stage biopharmaceutical company focused on delivering innovative medicines for patients with rare diseases, today announced the submission of its supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (FDA) for the U.S. accelerated approval of mitapivat, an oral pyruvate kinase (PK) activator, in sickle cell disease. The submission follows agreement with the FDA on the confirmatory clinical trial, which is required under the accelerated approval pathway.<\/p>\n<p>The confirmatory clinical trial is designed to demonstrate the clinical benefit of mitapivat on reducing transfusion burden in sickle cell disease, with a primary endpoint of transfusion free from Week 4 through Week 52. The global, randomized, double-blind, placebo-controlled, 52-week trial will enroll approximately 159 patients aged 12 years or older with sickle cell disease. The design of the confirmatory trial is informed by a clinically meaningful reduction in transfusion burden that was observed with mitapivat compared to placebo in the RISE UP Phase 3 trial based on data systematically and prospectively collected. These results will be included in an oral presentation on the RISE UP Phase 3 trial during the Plenary Abstracts Session at the 31<sup>st<\/sup> European Hematology Association (EHA) Congress on June 13, 2026, in Stockholm, Sweden.<\/p>\n<p>\u201cThe submission of the mitapivat sNDA represents an important milestone for the sickle cell community, which urgently needs new treatments that can address key underlying aspects of this debilitating and deadly disease,\u201d said Sarah Gheuens, M.D., Ph.D., Chief Medical Officer and Head of R&amp;D, Agios. \u201cThe sNDA is supported by data from the RISE UP clinical program demonstrating that mitapivat significantly improved hemoglobin concentration and reduced hemolysis in patients with sickle cell disease, translating into clinically meaningful benefits in pain crises and related hospitalizations, as well as fatigue, for those who achieved a hemoglobin response. This strong anti-hemolytic profile builds on clinical data that supported regulatory approvals in two other rare hemolytic anemias. We believe mitapivat is well-positioned to become the first PK activator approved in the U.S. for sickle cell disease, and we look forward to continued engagement with the FDA throughout the review process.\u201d<\/p>\n<p>The mitapivat sNDA is based on data from the global, randomized, double-blind, placebo-controlled RISE UP <a href=\"https:\/\/www.globenewswire.com\/Tracker?data=rtuKtt5KB0HANu_oU6Oz4ysy-qiPsWWB6yAbAgFp1Nwe0SvOubkJsrOQWMu5p23x7NTCTb2r1IU2VHkmfkD4S4-v-4L8TZ-8KrXIkH_oG1s9Dr52q5K5xsWbonvfHIk8hAIKu5ntbynfxjxMFbP7V0q9tBlSzXkUqpsAnX1SG9AEuH6jObMBBbRse0LQJI8sQVHQ2mui6OEsL1nb46NCsA==\" rel=\"nofollow\" target=\"_blank\">Phase 2<\/a> and <a href=\"https:\/\/www.globenewswire.com\/Tracker?data=rtuKtt5KB0HANu_oU6Oz40XGg3m415QngUNql_xxMDbpetSWAD_9aLFzFIqts0F2Rs3Nscy2U__bAHJ9itI_7qtP6FfcUmXFOMCiwWI77eqWgQKnaCnTcRvd9FpcCRzBh9wSr5ZJNYcdLq2ZHBr4UJ1dMp3OdWDSoCsFvHHXDSbAkJvgok3c6vWq6UH3gzTEJYojMJ4K4CMdcpK83rvdMw==\" rel=\"nofollow\" target=\"_blank\">Phase 3<\/a> trials. Agios expects to receive notice of the sNDA filing acceptance and anticipated review timeline in the third quarter of 2026, following the FDA\u2019s 60-day filing review period.<\/p>\n<p>\n        <strong>About U.S. Accelerated Approval<\/strong><br \/>\n        <br \/>The U.S. Food and Drug Administration\u2019s (FDA) accelerated approval pathway expedites the availability of medicines that can fill a medical need for a serious condition. A confirmatory clinical trial is required to convert the accelerated approval to a traditional approval, and this trial must be underway when the FDA makes its approval decision.<\/p>\n<p>\n        <strong>About Sickle Cell Disease<\/strong><br \/>\n        <br \/>Sickle cell disease is a rare, inherited blood disorder caused by the production of abnormal hemoglobin that disrupts the ability of red blood cells to carry oxygen throughout the body. As a result, red blood cells become rigid and sickle-shaped, causing deformation of red blood cell membranes and the premature death of the cells. These effects lead to chronic hemolytic anemia, vaso-occlusion, and a cascade of severe and life-threatening complications, including long-term damage to the lungs, kidneys, and cardiovascular system. Due to its physical toll, sickle cell disease imposes a profound burden on patients and their families, marked by increased healthcare needs and early mortality.<\/p>\n<p>\n        <strong>About Mitapivat in Sickle Cell Disease<\/strong><br \/>\n        <br \/>Mitapivat, an oral pyruvate kinase (PK) activator, is designed to enhance the process by which red blood cells produce energy. This approach has the potential to improve red blood cell health by increasing ATP levels to support increased energy demands and lowering levels of a molecule called 2,3-diphosphoglycerate (2,3-DPG). In sickle cell disease, increased stress on red blood cells results in elevated levels of 2,3-DPG, which raises the likelihood that red blood cells develop the abnormal \u201csickle\u201d shape that triggers vaso-occlusive crises.<\/p>\n<p>\n        <strong>About the RISE UP Phase 3 Trial Topline Results<\/strong><br \/>\n        <br \/>The global RISE UP Phase 3 trial (<a href=\"https:\/\/www.globenewswire.com\/Tracker?data=WqZn6EBCboIVPdEZLbiKnzZT0mUvtFLjUw5w2gAPU85hr2vauY9_hH_JtFQdB1H4M9f2PxpT_OH78j2O77tzKhxyY1R8v6AFXig3ZzIq8r7TCuCuVt3Vq7MGbf6nNfsT\" rel=\"nofollow\" target=\"_blank\">NCT05031780<\/a>) is evaluating the efficacy and safety of mitapivat in sickle cell disease patients aged 16 years or older, representative of the global population. The trial consisted of a 52-week, double-blind, randomized, placebo-controlled period, in which 207 participants were randomized 2:1 to receive oral mitapivat (100 mg) twice daily (n=138) or matched-placebo (n=69). Upon completion, participants could transition into an open-label extension (OLE) period where all receive mitapivat.<\/p>\n<p>To comprehensively evaluate objective measures of hemolysis alongside other clinically relevant outcomes in sickle cell disease, the double-blind period of RISE UP included two primary endpoints \u2013 hemoglobin response and annualized rate of sickle cell pain crises \u2013 as well as five key secondary endpoints measuring hemoglobin concentration, indirect bilirubin (a biomarker of hemolysis), patient-reported fatigue, hospitalizations for sickle cell pain crises, and percent reticulocyte levels (a biomarker of erythropoiesis).<\/p>\n<p>Mitapivat demonstrated a statistically significant improvement compared to placebo in the study\u2019s primary endpoint of hemoglobin response, defined as a \u22651.0 g\/dL increase from baseline in average hemoglobin concentration from Week 24 through Week 52. Although mitapivat showed a reduction in the annualized rate of sickle cell pain crises compared with placebo, this primary endpoint did not reach statistical significance.<\/p>\n<p>Patients receiving mitapivat who achieved the hemoglobin response primary endpoint had clinically meaningful improvements in hemoglobin concentration. These patients also experienced other clinically meaningful benefits, including reductions in pain crises and related hospitalizations, along with improvements in fatigue.<\/p>\n<p>The safety profile was consistent with prior mitapivat trials in sickle cell disease. The 52-week double-blind period was completed by 87.0% (n=120\/138) of patients in the mitapivat arm and 81.2% (n=56\/69) of patients in the placebo arm. All but two of these patients (174\/176) opted to enter the ongoing OLE period of the trial.<\/p>\n<p>\n        <strong>About Agios: Fueled by Connections to Transform Rare Diseases\u2122 <\/strong><br \/>\n        <br \/>At Agios, our vision is to redefine the future of rare disease treatment.
