SOUTH SAN FRANCISCO, Calif., Jan. 27, 2026 - Cytokinetics, Incorporated (Nasdaq: CYTK) today announced the launch of “On Track with HCM,” demonstrating the company’s long-standing commitment to the HCM community. The campaign features four-time Olympic gold medalist Sydney McLaughlin-Levrone, and her father, three-time all-American track star, Willie McLaughlin, who suffered from the non-obstructive form of hypertrophic cardiomyopathy (HCM) for more than two decades before receiving a heart transplant.

Designed in collaboration with the HCM patient advocacy community to support HCM patients as they navigate their everyday lives with the burdensome symptoms of the disease, the program includes a website and eight original videos featuring Sydney and Willie who share their personal experiences. HCM affected the McLaughlin family for more than two decades before Willie received a heart transplant, while Sydney and the family supported him through his journey. This program reflects on their experiences to inspire others facing this disease.
