\n Approval Triggers Milestone Payment of $7.5 Million from Sanofi;\u00a0<\/em>
\n
\n Cytokinetics Eligible to Receive Additional Milestone Payments and Royalties on Net Sales in Greater China<\/em>\n <\/p>\n

SOUTH SAN FRANCISCO, Calif., Dec. 17, 2025 (GLOBE NEWSWIRE) — Cytokinetics, Incorporated (Nasdaq: CYTK) today announced that MYQORZO\u00ae (aficamten)<\/em> has been approved by the China National Medical Products Administration (NMPA) for the treatment of adults with New York Heart Association (NYHA) class II-III obstructive hypertrophic cardiomyopathy (oHCM), to improve exercise capacity and symptoms.<\/p>\n

Under the terms of its license and collaboration agreement with Cytokinetics, Sanofi has exclusive rights to develop and commercialize MYQORZO for the treatment of patients with obstructive and non-obstructive hypertrophic cardiomyopathy (HCM) in Greater China. The approval of MYQORZO in oHCM in China triggers a $7.5 million milestone payment from Sanofi to Cytokinetics. Cytokinetics remains eligible to receive up to $142.5 million in development and commercial milestone payments from Sanofi as well as royalties in the low-to-high teens on future sales of MYQORZO in Greater China.<\/p>\n

MYQORZO is only approved for use in China. Aficamten<\/em> is currently under regulatory review in the U.S, where the FDA is reviewing a New Drug Application (NDA) for aficamten<\/em> with a Prescription Drug User Fee Act (PDUFA) target action date of December 26, 2025. On December 12, 2025 the Committee for Medicinal Products for Human Use (CHMP) of the EMA adopted a positive opinion recommending marketing authorization in the European Union (EU) for aficamten<\/em>, and a final decision is anticipated from the European Commission in the first quarter of 2026.<\/p>\n

\n About MYQORZO\u00ae (<\/strong>
\n
\n aficamten)<\/em>
\n <\/strong>\n <\/p>\n

MYQORZO\u00ae (aficamten) <\/em>is an investigational selective, small molecule cardiac myosin inhibitor discovered following an extensive chemical optimization program that was conducted with careful attention to therapeutic index and pharmacokinetic properties.1<\/sup> MYQORZO was designed to reduce the number of active actin-myosin cross bridges during each cardiac cycle and consequently suppress the myocardial hypercontractility that is associated with HCM. In preclinical models, MYQORZO reduced myocardial contractility by binding directly to cardiac myosin at a distinct and selective allosteric binding site, thereby preventing myosin from entering a force producing state.<\/p>\n

The development program for MYQORZO is assessing its potential as a treatment that improves exercise capacity as measured by peak oxygen uptake (pVO2<\/sub>) and relieves symptoms in patients with HCM. MYQORZO was evaluated in SEQUOIA-HCM, a positive pivotal Phase 3 clinical trial in patients symptomatic obstructive hypertrophic cardiomyopathy (HCM). MYQORZO received Breakthrough Therapy Designation for the treatment of symptomatic HCM from the U.S. Food & Drug Administration (FDA) and for the treatment of symptomatic obstructive HCM from the National Medical Products Administration (NMPA) in China.<\/p>\n

\n Aficamten <\/em>is also currently under clinical investigation in ACACIA-HCM, a Phase 3 trial in patients with non-obstructive HCM and CEDAR-HCM, in a pediatric population with oHCM. Aficamten<\/em> has not been deemed safe or effective for use in either of these patient populations. In addition, aficamten<\/em> is being studied in FOREST-HCM, an open-label extension clinical study.<\/p>\n

\n About Hypertrophic Cardiomyopathy<\/strong>\n <\/p>\n

Hypertrophic cardiomyopathy (HCM) is a disease in which the heart muscle (myocardium) becomes abnormally thick (hypertrophied). The thickening of cardiac muscle leads to the inside of the left ventricle becoming smaller and stiffer, and thus the ventricle becomes less able to relax and fill with blood. This ultimately limits the heart\u2019s pumping function, resulting in reduced exercise capacity and symptoms including chest pain, dizziness, shortness of breath, or fainting during physical activity. HCM is the most common monogenic inherited cardiovascular disorder, with approximately 280,000 patients diagnosed, however, there are an estimated 400,000-800,000 additional patients who remain undiagnosed in the U.S.2<\/sup>,<\/sup>3<\/sup>,<\/sup>4<\/sup> Two-thirds of patients with HCM have obstructive HCM (oHCM), where the thickening of the cardiac muscle leads to left ventricular outflow tract (LVOT) obstruction, while one-third have non-obstructive HCM (nHCM), where blood flow isn\u2019t impacted, but the heart muscle is still thickened. People with HCM are at high risk of also developing cardiovascular complications including atrial fibrillation, stroke and mitral valve disease.5<\/sup> People with HCM are at risk for potentially fatal ventricular arrhythmias and it is one of the leading causes of sudden cardiac death in younger people or athletes.6<\/sup> A subset of patients with HCM are at high risk of progressive disease leading to dilated cardiomyopathy and heart failure necessitating cardiac transplantation.<\/p>\n

\n About Cytokinetics <\/strong>\n <\/p>\n

Cytokinetics is a specialty cardiovascular biopharmaceutical company building on its over 25-years of pioneering scientific innovation in muscle biology, and advancing a pipeline of potential new medicines for patients suffering from diseases of cardiac muscle dysfunction with intention to create a muscle biology franchise business focused on medicines designed to optimize muscle performance for patients with cardiac and other diseases of muscle dysfunction. MYQORZO\u00ae (aficamten<\/em>), the company\u2019s cardiac myosin inhibitor, is approved for the treatment of patients with obstructive hypertrophic cardiomyopathy (HCM) in China, and under regulatory review in the U.S. The Committee for Medicinal Products for Human Use of the European Medicines Agency adopted a positive opinion recommending marketing authorization in the European Union for aficamten<\/em>, and a final decision is anticipated from the European Commission in the first quarter of 2026. Cytokinetics is also developing omecamtiv mecarbil<\/em>, a cardiac myosin activator, in patients with heart failure with severely reduced ejection fraction, ulacamten<\/em>, a cardiac myosin inhibitor with a mechanism of action distinct from aficamten, <\/em>for the potential treatment of heart failure with preserved ejection fraction and CK-089, a fast skeletal muscle troponin activator with potential therapeutic application to a specific type of muscular dystrophy and other conditions of impaired skeletal muscle function.<\/p>\n

\n About the Sanofi and Cytokinetics Collaboration<\/strong>\n <\/p>\n

In 2024, Sanofi acquired exclusive rights to develop and commercialize MYQORZO\u00ae (aficamten<\/em>) from Corxel Pharmaceuticals (CORXEL) for the treatment of patients with obstructive and non-obstructive hypertrophic cardiomyopathy (HCM) in Greater China. Previously, CORXEL acquired the rights to develop and commercialize MYQORZO in Greater China from Cytokinetics in accordance with Cytokinetics\u2019 global registration programs.<\/p>\n
