Q3 and Recent Highlights

Cardiac Muscle Programs

omecamtiv mecarbil (cardiac myosin activator)

• Continued activities supportive of our plans to submit a New Drug Application (NDA) for omecamtiv mecarbil, which remains on track to occur in Q4 2021.
• Results from additional analyses from GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure) were presented at the Heart Failure Society of America (HFSA) Annual Scientific Meeting in Denver, CO, showing that the effect of treatment with omecamtiv mecarbil in Black patients was consistent with the overall population and with white patients.
• Continued conduct of METEORIC-HF (Multicenter Exercise Tolerance Evaluation of Omecamtiv Mecarbil Related to Increased Contractility in Heart Failure), the second Phase 3 trial of omecamtiv mecarbil. We expect to complete METEORIC-HF by year end and report results in early 2022.

• Advanced our go-to-market-strategy and commercial readiness activities. We completed the hiring of our commercial senior leadership and payer account management teams and grew our U.S. marketing organization. In addition, we advanced key activities in preparation for potential commercial launch including refinement of product positioning, development of a product educational campaign, updating the sizing and deployment strategy for our U.S. sales team, U.S. pricing, and our product value proposition.
• Expanded our Medical Affairs organization with the hiring of therapeutic area lead Medical Directors and deployment of additional field-based Medical Scientists. We initiated vendor selection for the development of a Medical Contact Center and continued organizing the framework for the Investigator Sponsored Study Program.
• The manuscript entitled “Assessment of Omecamtiv Mecarbil for the Treatment of Patients with Severe Heart Failure” was published in JAMA Cardiology.
• The manuscript entitled “Characteristics and Outcomes of Patients with Heart Failure with Reduced Ejection Fraction After a Recent Worsening Heart Failure Event” was published in the Journal of the American Heart Association.

aficamten (cardiac myosin inhibitor)

• Announced positive results from Cohorts 1 and 2 of REDWOOD-HCM (Randomized Evaluation of Dosing With CK-274 in Obstructive Outflow Disease in HCM) demonstrating that treatment with aficamten for 10 weeks resulted in statistically significant reductions from baseline compared to placebo in the average resting left ventricular outflow tract pressure gradient (LVOT-G) and the average post-Valsalva LVOT-G. A large majority of patients treated with aficamten achieved the target goal of treatment, defined as resting gradient <30 mmHg and post-Valsalva gradient <50 mmHg at Week 10, compared to placebo. Patients treated with aficamten also saw improvements in heart failure symptoms and reductions in NT-proBNP, a biomarker of cardiac wall stress. Treatment with aficamten in REDWOOD-HCM was generally well tolerated. The incidence of adverse events on aficamten was similar to that of placebo. No serious adverse events were attributed to aficamten, and no treatment interruptions occurred on aficamten.
• Completed enrollment in Cohort 3 of REDWOOD-HCM for patients whose background therapy includes disopyramide. Continued enrolling patients in REDWOOD-HCM OLE, the open label extension clinical study designed to assess the long-term safety and tolerability of aficamten in patients with symptomatic obstructive HCM who have participated previously in REDWOOD-HCM. Results from Cohort 3 are expected in Q1 2022 and an update from REDWOOD-HCM OLE is expected in 2022.
• Conducted start-up activities, including regulatory filings and IRB submissions, for SEQUOIA-HCM (Safety, Efficacy, and Quantitative Understanding of Obstruction Impact of Aficamten in HCM), the Phase 3 clinical trial of aficamten in patients with obstructive HCM, with the first site initiations already completed. Drug product availability in early 2022 will enable the commencement of screening and enrollment of the first patients in this trial.
• Ji Xing Pharmaceuticals completed a Phase 1 study of aficamten in healthy subjects in China that showed favorable tolerability comparable to placebo and dose-proportional pharmacokinetics, similar to the results observed in the Phase 1 study of aficamten in healthy Caucasian subjects in the U.S.
• Published a manuscript entitled “Discovery of Aficamten (CK-274), a Next-Generation Cardiac Myosin Inhibitor for the Treatment of Hypertrophic Cardiomyopathy” in the Journal of Medicinal Chemistry.
• The manuscript entitled “Clinical Diagnosis of Hypertrophic Cardiomyopathy Over Time in the United States (A Population-Based Claims Analysis)” was published in The American Journal of Cardiology.

Skeletal Muscle Program

reldesemtiv (fast skeletal muscle troponin activator (FSTA))

• Started COURAGE-ALS (Clinical Outcomes Using Reldesemtiv on ALSFRS-R in a Global Evaluation in ALS), the Phase 3 clinical trial of reldesemtiv in patients with ALS.
• Published a manuscript entitled “Prescription and Acceptance of Durable Medical Equipment in FORTITUDE-ALS, a Study of Reldesemtiv in ALS: Post Hoc Analyses of a Randomized, Double-Blind, Placebo-Controlled Clinical Trial” in Amyotrophic Lateral Sclerosis and Frontotemporal Degeneration.
• Published a manuscript entitled “Discovery of Reldesemtiv, a Fast Skeletal Muscle Troponin Activator for the Treatment of Impaired Muscle Function” in Journal of Medicinal Chemistry.

Pre-Clinical Development and Ongoing Research

• Continued to advance new muscle directed compounds and conduct IND-enabling studies with the expectation of our potentially advancing 1-2 potential drug candidates into clinical development over the next year.
• Continued research activities directed to our other muscle biology research programs.

Financials

Revenues for the three and nine months ended September 30, 2021 were $5.4 million and $14.8 million, respectively, compared to $41.7 million and $49.1 million for the corresponding periods in 2020. The changes in revenues are due to our recognizing a $5.0 million milestone from Ji Xing Pharmaceuticals in anticipation of the start of SEQUOIA-HCM, the absence of licensing revenue, the absence of revenue from our prior collaboration with Amgen, and changes in reimbursable collaborative activities with Astellas.

Research and development expenses for the three and nine months ended September 30, 2021 increased to $48.4 and $116.4 million, respectively, compared to $24.2 million and $67.7 million for the same periods in 2020. The changes were primarily due to increases in spending for our clinical development activities for our cardiac muscle inhibitor programs and COURAGE-ALS. In addition, for the three and nine months ended September 30, 2021, we incurred transition costs related to the termination of our collaboration with Amgen and our purchase from Amgen of approximately $7.3 million and $14.6 million, respectively, of materials including manufactured quantities of the active pharmaceutical ingredient for omecamtiv mecarbil.

General and administrative expenses for the three and nine months ended September 30, 2021 increased by $13.9 million and $24.1 million, from the three and nine months ended September 30, 2020, respectively, primarily due to higher outside service spend in anticipation of the potential commercial launch of omecamtiv mecarbil, an increase in personnel related costs including stock-based compensation and facilities expense due to the Oyster Point Lease recorded at the end of the first quarter of 2021.
