Cytokinetics (CYTK) Is Up 8.7% After Aficamten Surpasses Metoprolol in Key HCM Trial Outcomes Has The Bull Case Changed?

• In November 2025, Cytokinetics announced that new data from the MAPLE-HCM trial showed aficamten provided greater improvements than metoprolol in multiple measures of hypertrophic cardiomyopathy, with higher responder rates and better patient-reported outcomes, presented at two major scientific conferences and published in a leading cardiology journal.
