Item 8.01. Other Events.

Today, February 15, 2022, Cytokinetics, Incorporated (the “Company” or “Cytokinetics”) announced topline results from METEORIC-HF (Multicenter Exercise Tolerance Evaluation of Omecamtiv Mecarbil Related to Increased Contractility in Heart Failure), a Phase 3 clinical trial of omecamtiv mecarbil in patients with heart failure with reduced ejection fraction (“HFrEF”). Omecamtiv mecarbil is an investigational, selective, small molecule cardiac myosin activator for the treatment of heart failure with reduced ejection fraction.

METEORIC-HF evaluated the effect of treatment with omecamtiv mecarbil compared to placebo on exercise capacity as determined by cardiopulmonary exercise testing (“CPET”) following 20 weeks of treatment in patients with HFrEF receiving standard of care therapy. The trial completed enrollment of 276 patients in June 2021. There was no effect on the primary endpoint, which was the change in peak oxygen uptake (“pVO₂ ”) on CPET from baseline to Week 20 in patients treated with omecamtiv mecarbil compared to placebo. Adverse events, including major cardiac events, were similar between the treatment arms and the safety profile of omecamtiv mecarbil in METEORIC-HF was consistent with prior clinical trials including GALACTIC-HF. Results from METEORIC-HF will be presented at the American College of Cardiology (ACC) 71^st Annual Scientific Session & Expo, in a Late Breaking Clinical Trial session on Sunday, April 3, 2022 from 9:45-9:55 a.m. ET.

Cytokinetics recently announced that the U.S. Food & Drug Administration (“FDA”) has accepted and filed the company’s New Drug Application (“NDA”) for omecamtiv mecarbil. The NDA is supported by the results from GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure), the Phase 3 cardiovascular outcomes clinical trial of omecamtiv mecarbil that enrolled over 8,000 patients in 35 countries across 945 sites. GALACTIC-HF demonstrated a statistically significant effect of treatment with omecamtiv mecarbil to reduce risk of the primary composite endpoint of cardiovascular (“CV”) death or heart failure events (heart failure hospitalization and other urgent treatment for heart failure) compared to placebo in patients treated with standard of care. Additional analyses from GALACTIC-HF demonstrated a greater treatment effect of omecamtiv mecarbil in patients with lower left ventricular ejection fraction (“LVEF”), as well as other characteristics that may indicate worsening heart failure.

About Omecamtiv Mecarbil

Omecamtiv mecarbil is an investigational, selective, small molecule cardiac myosin activator, the first of a novel class of myotropes¹ designed to directly target the contractile mechanisms of the heart, binding to and recruiting more cardiac myosin heads to interact with actin during systole. Omecamtiv mecarbil is designed to increase the number of active actin-myosin cross bridges during each cardiac cycle and consequently augment the impaired contractility that is associated with HFrEF. Preclinical research has shown that omecamtiv mecarbil increases cardiac contractility without increasing intracellular myocyte calcium concentrations or myocardial oxygen consumption.^2-4

The development program for omecamtiv mecarbil is assessing its potential for the treatment of HFrEF. Positive results from GALACTIC-HF, the first Phase 3 clinical trial of omecamtiv mecarbil demonstrated a statistically significant effect of treatment with omecamtiv mecarbil to reduce risk of the primary composite endpoint of CV death or heart failure events (heart failure hospitalization and other urgent treatment for heart failure) compared to placebo in patients treated with standard of care. No reduction in the secondary endpoint of time to CV death was observed. Adverse events and treatment discontinuation of study drug were balanced between treatment arms. The FDA has accepted for filing the NDA for omecamtiv mecarbil based on the results from GALACTIC-HF and has assigned a Prescription Drug User Fee Act (“PDUFA”) date of November 30, 2022.

About Cytokinetics

Cytokinetics is a late-stage biopharmaceutical company focused on discovering, developing and commercializing first-in-class muscle activators and next-in-class muscle inhibitors as potential treatments for debilitating diseases in which muscle performance is compromised. As a leader in muscle biology and the mechanics of muscle performance, the company is developing small molecule drug candidates specifically engineered to impact muscle function and contractility. Cytokinetics is readying for the potential commercialization of omecamtiv mecarbil, its cardiac muscle activator, following positive results from GALACTIC-HF, a large, international Phase 3 clinical trial in patients with heart failure. Cytokinetics is also developing aficamten, a next-generation cardiac myosin inhibitor, for the potential treatment of hypertrophic cardiomyopathies (“HCM”). The company has announced positive results from Cohorts 1, 2 and 3 in REDWOOD-HCM, a Phase 2 clinical trial of aficamten in patients with symptomatic obstructive HCM. Cytokinetics is conducting start-up activities for SEQUOIA-HCM, the Phase 3 clinical trial of aficamten in patients with obstructive HCM. Cytokinetics is also developing reldesemtiv, an investigational fast skeletal muscle troponin activator, currently the subject of COURAGE-ALS, a Phase 3 clinical trial in patients with amyotrophic lateral sclerosis (“ALS”). Cytokinetics continues its over 20-year history of pioneering innovation in muscle biology and related pharmacology focused to diseases of muscle dysfunction and conditions of muscle weakness.
