Over the last 24 hours, Cytokinetics has seen a wave of analyst price target increases driven primarily by the U.S. FDA approval of aficamten, now marketed as Myqorzo, for symptomatic obstructive hypertrophic cardiomyopathy. Leerink and Morgan Stanley both cited the drug’s differentiated label and a streamlined Risk Evaluation and Mitigation Strategy as key reasons for improving their commercial outlook and updating financial models, with Morgan Stanley additionally highlighting confidence in Cytokinetics’ ability to execute a strong product launch and benefit from near-term catalysts. Truist emphasized that the differentiated label should allow Myqorzo to generate substantial revenue in oHCM and modeled robust worldwide peak sales, expecting the launch to at least match the performance of rival therapy Camzyos. BofA also acknowledged the FDA approval as an important milestone but viewed the decision and labeling as largely in line with prior expectations, suggesting it does not fundamentally alter the existing investment debate. These developments, centered on regulatory success and improved commercialization prospects for Myqorzo, underpinned the cluster of upward revisions to analysts’ valuation models for Cytokinetics, though the articles did not specify the stock’s precise price movement over the period.
