Polaris Capital Management, LLC on Cytokinetics, Incorporated

Thesis

Polaris added Cytokinetics after FDA approval of Myqorzo for hypertrophic cardiomyopathy. The manager views Myqorzo as superior to Bristol Myers Squibb's Camzyos because it offers better symptom relief with simpler dosing. That perceived product advantage creates an opportunity for Cytokinetics to establish a meaningful position in the cardiomyopathy market. The investment therefore rests on translating regulatory approval and product differentiation into successful commercialization.
