Expect to Submit Supplemental NDA for Aficamten in Non-Obstructive HCM in Q4 2026

MYQORZO Launched in Germany, Approved in United Kingdom and
Regulatory Review Ongoing in Canada, Switzerland, Hong Kong and Taiwan

~$1.7 Billion in Cash, Cash Equivalents and Investments as of June 30, 2026

SOUTH SAN FRANCISCO, Calif., Aug. 06, 2026 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (Nasdaq: CYTK) reported a management update and financial results for the second quarter of 2026.

“Our second quarter results demonstrate commercial launch momentum for MYQORZO alongside continued excellence for our development pipeline, both hallmarks of continued strong execution for our maturing business. In the U.S., we continued to build launch velocity evidenced by expanding physician adoption and increasing patient access. Internationally, we launched MYQORZO in Germany and laid the foundation for broadening access to aficamten by submitting reimbursement dossiers alongside regulatory filings advancing in multiple countries in Europe,” said Robert I. Blum, Cytokinetics’ President and Chief Executive Officer. “We look forward to sharing results from ACACIA-HCM later this month and submitting a supplemental NDA to the U.S. Food and Drug Administration in the fourth quarter. Having also secured additional capital during the recent quarter, we have the financial resources to invest in both the global commercialization of MYQORZO and the continued progression of our pipeline, positioning us well to maximize the potential of our specialty cardiology franchise.”

Q2 and Recent Highlights

Cardiac Muscle Programs

MYQORZO ^® ( aficamten ) (cardiac myosin inhibitor)

• Continued U.S. commercial launch of MYQORZO for adults with symptomatic obstructive hypertrophic cardiomyopathy (oHCM), with increasing physician and patient awareness of MYQORZO driven by both strong engagement and successful marketing campaigns.
  
  
• Continued to drive launch momentum for MYQORZO. As of June 30, 2026:
  
  
  • Over 700 unique healthcare providers prescribed MYQORZO
  • Approximately 1,500 patients were dispensed MYQORZO
  • Over 80% of patients on therapy were on paid prescription
    
    

• Successfully brought MYQORZO to market in Germany in June.
  
  
• MYQORZO was granted marketing authorization across the United Kingdom by the Medicines and Healthcare products Regulatory Agency (MHRA) for the treatment of symptomatic (New York Heart Association, NYHA class II-III) oHCM in adult patients. At the same time, the National Institute for Health and Care Excellence (NICE) issued guidance recommending aficamten for use in England and Wales.
  
  
• MYQORZO received reimbursement approval, effective August 1, from The Dutch Ministry of Health in the Netherlands.
  
  
• Submitted 10 Health Technology Assessment (HTA) dossiers to support market access across Europe and expect to launch in more than five additional markets by the first half of 2027.
  
  
• Submitted New Drug Applications (NDA) for aficamten in Hong Kong and Taiwan under our collaboration with Sanofi. Aficamten was granted priority review designation by the Taiwan Food & Drug Administration. Regulatory filings for MYQORZO are also under review in Canada and Switzerland.
  
  
• Announced positive topline results from ACACIA-HCM, the pivotal Phase 3 clinical trial of aficamten in patients with symptomatic non-obstructive hypertrophic cardiomyopathy (nHCM).
  
  
  • ACACIA-HCM met both dual primary endpoints, demonstrating statistically significant improvements from baseline to Week 36 in both Kansas City Cardiomyopathy Questionnaire (KCCQ) Clinical Summary Score and maximal exercise performance (peak VO₂).
  • Statistically significant improvements compared to placebo were also observed in key secondary endpoints.
  • There were no new safety signals identified. Left ventricular ejection fraction (LVEF) <50% occurred in 10% of participants taking aficamten and in 1% of participants taking placebo while treatment interruptions due to LVEF <40% were rare. Two participants on aficamten experienced a serious adverse event of heart failure associated with LVEF <50%.
    
    

• The primary results from ACACIA-HCM will be presented in a Hot Line Session at the European Society of Cardiology (ESC) Congress in August 2026. We expect to file a Supplemental NDA for nHCM in Q4 2026.
  
  
• Advanced the ongoing clinical trials program for aficamten:
  
  
  • Continued conduct of the Japan cohort of ACACIA-HCM. We expect to complete trial conduct in Q3 2026.
  • Continued conduct of CAMELLIA-HCM, a Phase 3 clinical trial of aficamten in Japanese patients with oHCM. CAMELLIA-HCM is being conducted by Bayer in collaboration with Cytokinetics to support potential marketing authorization in Japan. We expect to complete trial conduct in Q3 2026.
  • Recently completed patient enrollment in the adolescent cohort of CEDAR-HCM, a clinical trial of aficamten in a pediatric population with symptomatic oHCM.
    
    

• Presented new analyses at the ESC Heart Failure 2026 Congress from SEQUOIA-HCM, MAPLE-HCM and FOREST-HCM supporting previously published data related to the safety and efficacy of aficamten in oHCM.
  
  

omecamtiv mecarbil (cardiac myosin activator)

• Continued conduct of COMET-HF, a confirmatory Phase 3 clinical trial of omecamtiv mecarbil in patients with symptomatic heart failure with severely reduced ejection fraction. We expect to continue patient enrollment through 2026.
  
  

ulacamten (cardiac myosin inhibitor)

• Continued conduct of Cohort 1 of AMBER-HFpEF, a Phase 2 clinical trial of ulacamten in patients with symptomatic heart failure with preserved ejection fraction (HFpEF) with left ventricular ejection fraction (LVEF) ≥ 60%. We expect to complete patient enrollment in Cohort 1 in the second half of 2026.
  
  

CK-4015089 (CK-089, fast skeletal muscle troponin activator)

• Recently initiated the second Phase 1 randomized, double-blind, placebo-controlled single ascending dose clinical study of CK-4015089 (CK-089) in healthy human participants.
  
  

Pre-Clinical Development and Ongoing Research

• Continued pre-clinical development and research activities directed to additional muscle biology focused programs.

2026 Financial Guidance

The company is updating its full year 2026 financial guidance:

GAAP combined R&D and SG&A expense guidance increase is primarily driven by commercial readiness investments, prompted by the positive results from ACACIA-HCM, to support the potential 2027 launch of MYQORZO in nHCM.

The financial guidance does not include the effect of GAAP adjustments as may be caused by events that occur subsequent to publication of this guidance including, but not limited to, Business Development activities.
