SOUTH SAN FRANCISCO, Calif., May 08, 2024 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (Nasdaq: CYTK) reported financial results for the first quarter of 2024. Net loss for the first quarter was $135.6 million, or $1.33 per share, compared to net loss for the first quarter of 2023 of $131.3 million, or $1.38 per share. Cash, cash equivalents and investments totaled $634.3 million at March 31, 2024.

“In the first quarter, we advanced our muscle-biology portfolio anchored by the broad development program of aficamten. In parallel with our preparation of regulatory submissions in multiple geographies alongside executing on our go-to-market strategies, we also furthered ongoing clinical trials, FOREST-HCM, MAPLE-HCM and ACACIA-HCM, and opened enrollment to a fourth clinical trial of aficamten, CEDAR-HCM, a clinical trial in pediatric patients with obstructive HCM, another underserved cohort of patients with HCM,” said Robert I. Blum, Cytokinetics’ President and Chief Executive Officer. “At the same time, we progressed CK-586 towards a Phase 2 clinical trial expected to begin later this year. We believe that our cohesive biology anchored in cardiac myosin positions the company well to fulfill our mission to deliver important medicines and increase shareholder value as will be further enabled by solid financials, access to diversified capital and executing on capital efficient Business and Corporate Development plans.”

Q1 and Recent Highlights

Cardiac Muscle Programs

aficamten (cardiac myosin inhibitor)

  • Announced three late-breaking clinical trial presentations relating to SEQUOIA-HCM (Safety, Efficacy, and Quantitative Understanding of Obstruction Impact of Aficamten in HCM), at the European Society of Cardiology Heart Failure 2024 Congress on May 13, 2024 in Lisbon, Portugal.

  • Participated in two meetings with the U.S. Food and Drug Administration (FDA) related to our New Drug Application (NDA) for aficamten, and continued activities supportive of our plan to submit the NDA in Q3 2024. Readied for a Type B meeting with FDA scheduled to occur in Q2 2024 to discuss key data that inform safety monitoring and risk minimization strategies for aficamten.

  • Continued preparing our Marketing Authorization Application (MAA) for aficamten, which we expect to submit to the European Medicines Agency (EMA) in Q4 2024.

  • Continued commercial readiness activities for aficamten including refining our market development campaign and product positioning as well as initiating the design and build of our patient support services program. Completed profiling HCM treatment programs, finalized our Payor Clinical Value Proposition and began development of our Payer Clinical Value Deck.

  • Presented additional data from FOREST-HCM (Follow-up, Open-Label, Research Evaluation of Sustained Treatment with Aficamten in HCM) in April at the American College of Cardiology 73ʳᵈ Annual Scientific Session demonstrating that treatment with aficamten for 48 weeks was associated with improvements in clinical efficacy endpoints, New York Heart Association (NYHA) Functional Class and cardiac biomarkers, structure and function, and was well-tolerated.

  • Opened enrollment to CEDAR-HCM (Clinical Evaluation of Dosing with Aficamten to Reduce Obstruction in a Pediatric Population in HCM), a clinical trial of aficamten in a pediatric population with symptomatic obstructive HCM.

  • Continued enrolling patients in MAPLE-HCM (Metoprolol vs Aficamten in Patients with LVOT Obstruction on Exercise Capacity in HCM), the Phase 3 clinical trial comparing aficamten as monotherapy to metoprolol as monotherapy in patients with symptomatic obstructive HCM. Enrollment is expected to be completed in Q3 2024.

  • Continued enrolling patients in ACACIA-HCM (Assessment Comparing Aficamten to Placebo on Cardiac Endpoints In Adults with Non-Obstructive HCM), the pivotal Phase 3 clinical trial of aficamten in patients with non-obstructive HCM. We expect to continue enrollment throughout 2024.

  • Published the following manuscripts:

    • “Exercise Capacity in Patients with Obstructive Hypertrophic Cardiomyopathy: SEQUOIA-HCM Baseline Characteristics and Study Design” in the Journal of the American College of Cardiology: Heart Failure.

    • “Efficacy and Safety of Aficamten in Symptomatic Non-Obstructive Hypertrophic Cardiomyopathy: Results From the REDWOOD-HCM Trial, Cohort 4” in the Journal of Cardiac Failure.

omecamtiv mecarbil (cardiac myosin activator)

  • Withdrew the Marketing Authorization Application (MAA) from the European Medicines Agency (EMA) for omecamtiv mecarbil based on feedback from the Committee for Medicinal Products for Human Use (CHMP) indicating that the Committee will not be able to conclude that the benefits outweigh the risks on the basis of the results from GALACTIC-HF alone.

CK-4021586 (CK-586, cardiac myosin inhibitor)

  • Announced topline data from the Phase 1 study of CK-586. The data support progression to a Phase 2 clinical trial in patients with heart failure with preserved ejection fraction (HFpEF) which we expect to start in Q4 2024.

CK-3828136 (CK-136, cardiac troponin activator)

  • Completed the Phase 1 study of CK-136 and began data analyses.

Pre-Clinical Development and Ongoing Research

  • Continued pre-clinical development and research activities directed to additional muscle biology focused programs. We expect to initiate clinical development with another muscle directed compound later this year.


  • Announced the appointment of Sung Lee to serve as the Company’s Executive Vice President, Chief Financial Officer effective as of May 8, 2024.

  • Released 2023 Corporate Responsibility Report outlining the Company’s commitment and activities related to social and environmental responsibility, ethics and governance and patient and community engagement.

  • Awarded Cytokinetics Communications Fellowship Grants to patient advocacy organizations serving the HCM, heart failure and amyotrophic lateral sclerosis (ALS) communities to support increased capacity in communications, awareness building and community engagement.

  • Announced the launch of ENACT: Empower, Navigate, Activate for Clinical Trials, a joint initiative with The Mended Hearts, Inc. and WomenHeart: The National Coalition for Women with Heart Disease, to champion greater awareness and engagement in cardiovascular clinical trials by reducing barriers, increasing support and empowering patients in groups historically underrepresented in clinical research.


Revenues for the first quarter 2024 were $0.8 million compared to $4.6 million for the corresponding period in 2023. The decrease in revenues was primarily due to milestone revenue of $2.5 million received from Ji Xing Pharmaceuticals for the start of ACACIA-HCM and higher collaboration revenues in 2023.

Research and development expenses for the first quarter 2024 increased to $81.6 million compared to $79.4 million for the same period in 2023, due to spending for our clinical development activities for our cardiac myosin inhibitor programs.

General and administrative expenses for the first quarter 2024 decreased to $45.5 million from $49.7 million for the same period in 2023 due to lower outside spending for pre-commercial launch activities.

About Cytokinetics 

Cytokinetics is a late-stage, specialty cardiovascular 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 cardiac 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 myocardial muscle function and contractility. Cytokinetics is preparing for regulatory submissions for aficamten, its next-in-class cardiac myosin inhibitor, following positive results from SEQUOIA-HCM, the pivotal Phase 3 clinical trial in obstructive hypertrophic cardiomyopathy. Aficamten is also currently being evaluated in MAPLE-HCM, a Phase 3 clinical trial of aficamten as monotherapy compared to metoprolol as monotherapy in patients with obstructive HCM, ACACIA-HCM, a Phase 3 clinical trial of aficamten in patients with non-obstructive HCM, CEDAR-HCM, a clinical trial of aficamten in a pediatric population with obstructive HCM, and FOREST-HCM, an open-label extension clinical study of aficamten in patients with HCM. Cytokinetics is also developing omecamtiv mecarbil, a cardiac muscle activator, in patients with heart failure. Additionally, Cytokinetics is developing CK-586, a cardiac myosin inhibitor with a mechanism of action distinct from aficamten for the potential treatment of HFpEF, and CK-136, a cardiac troponin activator for the potential treatment HFrEF and other types of heart failure, such as right ventricular failure resulting from impaired cardiac contractility.
