Cytokinetics Unveils Pivotal New Data for Aficamten, Igniting Hope in oHCM Treatment at ESC Congress 2025

Cytokinetics, a leading biopharmaceutical company, made waves at the prestigious European Society of Cardiology (ESC) Congress 2025, presenting compelling new data related to Aficamten, its pioneering investigational cardiac myosin inhibitor. This highly anticipated presentation reinforced Aficamten's potential as a transformative therapeutic option for patients battling obstructive hypertrophic cardiomyopathy (oHCM), a debilitating genetic heart condition.

The data shared at the congress provided further insights into Aficamten's sustained efficacy and favorable safety profile, building upon the promising results previously observed in its clinical development program.

Researchers highlighted long-term outcomes and detailed subgroup analyses, demonstrating consistent benefits across diverse patient populations. These findings underscore Aficamten's ability to significantly improve exercise capacity, reduce left ventricular outflow tract (LVOT) gradients, and alleviate the burdensome symptoms that profoundly impact the quality of life for oHCM patients, such as dyspnea and fatigue.

Obstructive hypertrophic cardiomyopathy affects an estimated one in 500 individuals globally, characterized by excessive thickening of the heart muscle, leading to impaired blood flow and increased risk of serious cardiovascular events.

Current treatment options are often limited and may not adequately address the underlying pathophysiology of the disease, leaving a significant unmet medical need. Aficamten is designed to selectively reduce hypercontractility in the heart, directly targeting the root cause of oHCM.

During the presentation, key opinion leaders and Cytokinetics' clinical development team emphasized the drug's potential to offer a much-needed, non-invasive treatment alternative to existing therapies, including surgical myectomy or alcohol septal ablation.

The data presented further illuminated Aficamten's tolerability, with adverse events reported to be generally mild to moderate and consistent with previous observations, reinforcing its potential for long-term use in a chronic condition.

"We are incredibly excited by the new data on Aficamten presented at the ESC Congress 2025, which further solidifies its profile as a highly promising therapeutic for oHCM," stated a representative from Cytokinetics.

"These findings not only deepen our understanding of Aficamten's robust efficacy and safety but also reaffirm our commitment to bringing innovative solutions to patients living with this challenging disease. We believe Aficamten has the potential to fundamentally shift the treatment paradigm, offering renewed hope and improved outcomes for individuals suffering from oHCM worldwide."

The positive reception of this data at one of the world's largest and most influential cardiology congresses underscores the scientific community's growing optimism for Aficamten.

Cytokinetics continues to advance its clinical development program, working towards regulatory submissions and ultimately, making this vital treatment available to patients globally. The advancements showcased at ESC 2025 represent a significant stride forward in the fight against obstructive hypertrophic cardiomyopathy, marking a pivotal moment in the quest for more effective and patient-friendly therapies.
