SOUTH SAN FRANCISCO, Calif., Nov. 06, 2024 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (NASDAQ:CYTK) reported a management update and financial results for the third quarter of 2024.

"The progress we made in the third quarter reflects disciplined planning and prudent capital deployment throughout 2024 that has laid the foundation for our specialty cardiology business. The submission of the NDA for aficamten is an important regulatory milestone that brings us one step closer to the potential approval and commercial launch of aficamten in the United States alongside the scale-up of global workstreams," said Robert I. Blum, Cytokinetics' President and Chief Executive Officer. "While aficamten remains our top priority, our development pipeline is advancing and expanding with later-stage cardiovascular drug candidates as well as an earlier potential medicine focused to neuromuscular indications. With more than $1 billion on the balance sheet and access to additional long-term capital, we are well-funded and well-prepared to sustain momentum into 2025 with objective to deliver on the promise of our science for patients and to deliver meaningfully increased value to shareholders."

Q3 and Recent Highlights

Cardiac Muscle Programs

aficamten (cardiac myosin inhibitor)

Completed the rolling submission of the New Drug Application (NDA) for aficamten and submitted the NDA for the treatment of obstructive hypertrophic cardiomyopathy (HCM).
Presented additional results from SEQUOIA-HCM (Safety, Efficacy, and Quantitative Understanding of Obstruction Impact of Aficamten in HCM) at the European Society of Cardiology 2024 Congress, Heart Failure Society of America (HFSA) Annual Scientific Meeting and Hypertrophic Cardiomyopathy Medical Society Scientific Sessions. Collectively, the data showed that treatment with aficamten in SEQUOIA-HCM was associated with improvements in cardiac structure and function, heart failure symptoms, cardiac biomarkers, and multiple assessments of clinical significance to cardiologists.
Presented additional data related to the longer-term use of aficamten at the European Society of Cardiology 2024 Congress from an integrated safety analysis of three clinical studies of aficamten that reinforced the robust safety profile of aficamten. Additionally, an analysis from FOREST-HCM (Follow-up, Open-Label, Research Evaluation of Sustained Treatment with Aficamten in HCM,) the open label extension clinical study of aficamten in patients with HCM, demonstrated that patients who attempted withdrawal of standard of care medications did not experience negative impacts on the efficacy or safety of aficamten.
Continued U.S. commercial readiness activities for aficamten including selecting third-party external partners for our bespoke patient support programs and distribution strategy, refining our sales force strategy, engaging with payers through pre-approval information exchange and developing our U.S. value dossier. Launched "HCM Beyond the Heart," an unbranded disease awareness campaign for healthcare professionals highlighting the holistic burden of HCM.
Continued preparing a Marketing Authorization Application (MAA) for aficamten, expected to be submitted to the European Medicines Agency (EMA) and National Agencies in the EU in Q4 2024.
Continued European commercial readiness activities including designing the distribution model, refining regulatory and labeling strategies, establishing country launch sequencing, and engaging with European key opinion leaders. Established initial go-to-market plans for Germany, the first potential European market launch.

Corxel (formerly Ji Xing Pharmaceuticals) completed submission of the NDA for aficamten to treat obstructive HCM, which was accepted by the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA) in China.
Completed enrollment 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. We expect to report topline results from MAPLE-HCM in 1H 2025.
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 complete enrollment in ACACIA-HCM in 2025.
Continued patient enrollment in 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. We expect to continue enrollment in CEDAR-HCM throughout 2024.

omecamtiv mecarbil (cardiac myosin activator)

Conducted start-up activities for COMET-HF (Confirmation of Omecamtiv Mecarbil Efficacy Trial in Heart Failure), a confirmatory Phase 3 multi-center, double-blind, randomized, placebo-controlled trial to assess the efficacy and safety of omecamtiv mecarbil in patients with symptomatic heart failure with severely reduced ejection fraction, expected to start in Q4 2024.

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

Presented data from the Phase 1 study of CK-586 at the American College of Clinical Pharmacology (ACCP) Annual Meeting. The study met its primary and secondary objectives to assess the safety, tolerability and pharmacokinetics of single and multiple oral doses of CK-586.
Conducted start-up activities for AMBER-HFpEF (Assessment of CK-586 in a Multi-Center, Blinded Evaluation of Safety and Tolerability Results in HFpEF), a Phase 2 randomized, placebo-controlled, double-blind, multi-center, dose-finding clinical trial in patients with symptomatic heart failure with preserved ejection fraction (HFpEF) with left ventricular ejection fraction (LVEF) ≥ 60%, expected to start in Q4 2024.

Pre-Clinical Development and Ongoing Research

Expect to advance CK-4015089 (CK-089), a fast skeletal muscle troponin activator (FSTA) with potential therapeutic application to a specific type of muscular dystrophy, into a first-in-human Phase 1 study in Q4 2024.
Continued pre-clinical development and research activities directed to additional muscle biology focused programs.

About Cytokinetics

Cytokinetics is a late-stage, specialty cardiovascular biopharmaceutical company focused on discovering, developing and commercializing muscle biology-directed drug candidates 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. Following positive results from SEQUOIA-HCM, the pivotal Phase 3 clinical trial evaluating aficamten, a next-in-class cardiac myosin inhibitor, in obstructive hypertrophic cardiomyopathy (HCM), Cytokinetics submitted an NDA for aficamten to the U.S. Food & Drug Administration and is progressing regulatory submissions for aficamten for the treatment of obstructive HCM in Europe. 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 with severely reduced ejection fraction (HFrEF), CK-586, a cardiac myosin inhibitor with a mechanism of action distinct from aficamten for the potential treatment of heart failure with preserved ejection fraction (HFpEF), and CK-089, a fast skeletal muscle troponin activator (FSTA) for the potential treatment of a specific type of muscular dystrophy.
