Item 8.01. Other Events.

 

Today, October 7, 2021, Cytokinetics, Incorporated (the “Company” or “Cytokinetics”) outlined its go-to-market strategy for omecamtiv mecarbil in the United States and presented updates on its advancing cardiovascular pipeline and strategies to build a commercial franchise at “Charting the Commercial Course” at an Analyst and Investor Day presentation held today. The Registrant also presented the clinical trial design for SEQUOIA-HCM, the Phase 3 clinical trial of aficamten in patients with obstructive hypertrophic cardiomyopathy (“oHCM”).

 

The presentation presented is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

 

Go-To-Market Strategy for Omecamtiv Mecarbil

 

Cytokinetics leadership outlined the go-to-market strategy for omecamtiv mecarbil in the U.S., which will be guided by a sequenced build of core capabilities to ensure success based on key de-risking milestones leading up to the potential launch of omecamtiv mecarbil. The four pillars of the strategy include first, establishing a deep understanding of patients with worsening heart failure and the healthcare providers and associated institutions who treat this subset of heart failure patients. Second, engaging and educating cardiologists who treat patients with worsening heart failure about the disease state and the importance of appropriate treatment. Third, working with payers to ensure affordable managed care access to omecamtiv mecarbil. Finally, supporting patients and caregivers through education, co-pay assistance where applicable, and innovative models for patient support.

 

SEQUOIA-HCM: Phase 3 Clinical Trial of Aficamten

 

Cytokinetics also today presented the design of SEQUOIA-HCM (Safety, Efficacy, and Quantitative Understanding of Obstruction Impact of Aficamten in HCM). SEQUOIA-HCM is a Phase 3 randomized, placebo-controlled, double-blind, multi-center clinical trial designed to evaluate aficamten in patients with symptomatic oHCM on background medical therapy for 24 weeks. The primary objective is to assess the effect of aficamten on change in peak oxygen uptake (pVO2) measured by cardiopulmonary exercise testing (“CPET”) from baseline to week 24. Secondary objectives include change in Kansas City Cardiomyopathy Questionnaire (“KCCQ”) score from baseline to week 12 and week 24, the proportion of patients with ≥1 class improvement in New York Heart Association (“NYHA”) functional class from baseline to week 12 and week 24, change in post-Valsalva left ventricular outflow tract gradient (“LVOT-G”) to week 12 and week 24, the proportion of patients with post-Valsalva LVOT-G <30 mmHg, and change in total workload during CPET to week 24.

 

SEQUOIA-HCM is planned to enroll 270 patients, randomized on a 1:1 basis to receive aficamten or placebo in addition to standard-of-care treatment. Each patient will receive up to four escalating doses of aficamten or placebo based on echocardiographic guidance alone. At screening, patients enrolled in SEQUOIA-HCM must have a resting LVOT-G ≥30 mmHg, post-Valsalva peak LVOT-G ≥50 mmHg, and be NYHA Class II or III. Patients receiving aficamten will begin with 5 mg dosed once daily. At weeks 2, 4 and 6 patients will receive an echocardiogram to determine if they will be up-titrated to escalating doses of 10, 15 or 20 mg. Dose escalation will occur only if a patient has a post-Valsalva LVOT-G ≥30 mmHg and a biplane left ventricular ejection fraction (“LVEF”) ≥55%. Patients who do not meet escalation criteria will continue to receive their current dose or may be down-titrated if appropriate. Cytokinetics expects to begin SEQUOIA-HCM in Q4 2021.

 

 

Panel of Physician Experts

 

At today’s Analyst & Investor Day, a panel of heart failure experts including Tariq Ahmad, MD, MPH, Associate Professor of Medicine; Medical Director of Advanced Heart Failure, Cardiovascular Medicine, Yale School of Medicine, and Alanna Morris, MD, MSc, FHFSA, FACC, FAHA, Associate Professor of Medicine, Division of Cardiology; Director of Heart Failure Research, Emory University Clinical Cardiovascular Research Institute, discussed challenges of treating patients with heart failure with reduced ejection fraction (“HFrEF”) and the unmet need in this patient population.

 

Cardiovascular Franchise Strategy

 

The Company elaborated on its strategy to build a cardiovascular franchise by leveraging investments in people, relationships and infrastructure made during the potential commercialization of omecamtiv mecarbil to support the potential future commercialization of aficamten. The franchise strategy would be enabled by multiple cardiovascular medicines that allow for long-term and effective communications with cardiologists, efficiencies in spend, and field force synergies given the significant overlap of cardiologists and hospitals that treat both patients with worsening heart failure as well as HCM.

 

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 was 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 and includes GALACTIC-HF and METEORIC-HF, a Phase 3 clinical trial designed to evaluate the effect of treatment with omecamtiv mecarbil compared to placebo on exercise capacity.

 

About Aficamten

 

Aficamten 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 that may translate into next-in-class potential in clinical development. Aficamten was designed to reduce the number of active actin-myosin cross bridges during each cardiac cycle and consequently suppress myocardial hypercontractility that is associated with hypertrophic cardiomyopathy (“HCM”). In preclinical models, aficamten 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.

 

The development program for aficamten is assessing its potential for the treatment of HCM and to improve exercise capacity and relieve symptoms in patients with hyperdynamic ventricular contraction and includes REDWOOD-HCM, a Phase 2 clinical trial designed to evaluate the effect of treatment with aficamten compared to placebo on measures of safety, tolerability as well as pharmacodynamics and biomarkers.

 

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 preparing a U.S. NDA submission of omecamtiv mecarbil, its novel cardiac muscle activator, following positive results from GALACTIC-HF, a large, international Phase 3 clinical trial in patients with heart failure. Cytokinetics is conducting METEORIC-HF, a second Phase 3 clinical trial of omecamtiv mecarbil. Cytokinetics is also developing aficamten, a next-generation cardiac myosin inhibitor, for the potential treatment of HCM. The company has announced positive results from Cohorts 1 and 2 in REDWOOD-HCM, a Phase 2 clinical trial of aficamten in patients with obstructive HCM. Cytokinetics expects to start SEQUOIA-HCM, the Phase 3 clinical trial of aficamten in patients with obstructive HCM in Q4 2021. Cytokinetics is also developing reldesemtiv, a fast skeletal muscle troponin activator, currently the subject of COURAGE-ALS, a Phase 3 clinical trial in patients with 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.
