SOUTH SAN FRANCISCO, Calif., Aug. 08, 2024 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (Nasdaq: CYTK) reported a management update and financial results for the second quarter of 2024.

“Cytokinetics made substantial progress during the second quarter across our pipeline and aligned to near-term goals as well as our longer-term vision to build a sustainable specialty cardiology business. In May, we secured contingent access to more than $1 billion in funding to support the potential global launch of aficamten as well as to continue conduct of label-expanding clinical trials of aficamten worldwide and to advance our later-stage pipeline including omecamtiv mecarbil and CK-586,” said Robert I. Blum, Cytokinetics’ President and Chief Executive Officer. “These three programs, anchored in our pioneering science of myosin modulation, provide synergistic opportunities in adjacent specialty cardiology indications that we believe will unlock shareholder value while making good on our promise to patients.”

Q2 and Recent Highlights

Cardiac Muscle Programs

aficamten (cardiac myosin inhibitor)

• Presented primary results from SEQUOIA-HCM (Safety, Efficacy, and Quantitative Understanding of Obstruction Impact of Aficamten in HCM) at the European Society of Cardiology Heart Failure 2024 Congress, demonstrating statistically significant and clinically meaningful improvements in the primary efficacy endpoint of peak oxygen uptake (pVO₂) and all secondary endpoints with results consistent across all prespecified subgroups. Additional results presented from SEQUOIA-HCM showed that treatment with aficamten resulted in predictable dosing with no dose interruptions or associated heart failure due to left ventricular ejection fraction (LVEF) <50% and improved a novel integrated exercise performance metric. Improvements in pVO₂ were shown to be highly correlated with improvements in cardiac structure and function.

• Participated in a Type B meeting with the U.S. Food and Drug Administration (FDA) to discuss potential strategies related to safety monitoring and risk mitigation for aficamten and included a review of how results from SEQUOIA-HCM and intrinsic properties of aficamten may inform risk mitigation. The Company expects to propose a distinct risk mitigation approach specific to aficamten with the New Drug Application (NDA) for which the rolling submission is underway. The Company is on track to complete the rolling NDA submission for aficamten in Q3 2024.
  
  
• The FDA recently cleared a protocol amendment for FOREST-HCM (Follow-up, Open-Label, Research Evaluation of Sustained Treatment with Aficamten in HCM) reducing the frequency of echocardiographic monitoring for patients with obstructive HCM to every 6 months during maintenance treatment for patients with LVEF >55%.
  
  
• Participated in meetings with the European Medicines Agency (EMA) and National Agencies in the EU during which the company confirmed plans to submit a Marketing Authorization Application (MAA) for aficamten in Q4 2024 and discussed the content of the expected filing.
  
  
• Coordinated with Ji Xing Pharmaceuticals to support the planned submission of an NDA for aficamten to the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA) in China in 2H 2024.
  
  
• Continued commercial readiness activities for aficamten including refining our market development campaign, designing the treatment experience inclusive of distribution and patient support programs, advancing key market research, and finalizing the structure for the field-based sales team. Began pre-approval information exchange activities to proactively share health care economic and scientific information with payers and initiated development of U.S. and global value dossiers.
  
  
• Initiated a Phase 1 study evaluating the pharmacokinetics, safety and tolerability of aficamten in healthy Japanese and Caucasian participants. We expect to continue enrollment throughout 2024.
  
  
• 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. We expect to continue enrollment in CEDAR-HCM throughout 2024.
  
  
• 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. We expect to complete enrollment in MAPLE-HCM 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 in ACACIA-HCM throughout 2024 and complete enrollment in 2025.
