- Cytokinetics presented additional data for **aficamten** at the European Society of Cardiology Congress 2025, demonstrating that it **improves cardiac structure and function compared to metoprolol** and has a **low annual incidence rate of atrial fibrillation (1.5%)**.  **[1061983_657ded3ca5484bbb82dd26c7408bb276_0]** **[1061983_657ded3ca5484bbb82dd26c7408bb276_1]** **[1061983_657ded3ca5484bbb82dd26c7408bb276_2]** 
- An integrated safety analysis confirmed that **aficamten is well-tolerated** with an adverse event profile similar to placebo, showing a low incidence of new-onset atrial fibrillation (1.9%).  **[1061983_657ded3ca5484bbb82dd26c7408bb276_3]** 
- **Aficamten** is currently under regulatory review by the FDA in the U.S., with a **Prescription Drug User Fee Act (PDUFA) target action date of December 26, 2025**.  **[1061983_657ded3ca5484bbb82dd26c7408bb276_0]** **[1061983_657ded3ca5484bbb82dd26c7408bb276_4]**

Cytokinetics Presents Positive Aficamten Clinical Data and Confirms Regulatory Review Timeline

- Cytokinetics announced positive primary results from the Phase 3 MAPLE-HCM clinical trial, demonstrating the superiority of **_aficamten_** over **_metoprolol_** in patients with symptomatic obstructive hypertrophic cardiomyopathy (oHCM).  **[1061983_43b03c6024064d97bc0dfcf9d050ff6e_0]** 
- The trial's primary endpoint showed a statistically significant improvement in exercise capacity, with a least-squares mean difference of **2.3 mL/kg/min** (p<0.0001) in peak oxygen uptake (pVO2) for **_aficamten_** compared to **_metoprolol_** after 24 weeks.  **[1061983_43b03c6024064d97bc0dfcf9d050ff6e_1]** 
- **_Aficamten_** also demonstrated superiority in five of six secondary endpoints, including improvements in functional class and reduced patient symptom burden.  **[1061983_43b03c6024064d97bc0dfcf9d050ff6e_2]** 
- **_Aficamten_** is currently under regulatory review by the U.S. Food and Drug Administration (FDA), with a Prescription Drug User Fee Act (PDUFA) target action date of **December 26, 2025**.  **[1061983_43b03c6024064d97bc0dfcf9d050ff6e_1]** **[1061983_43b03c6024064d97bc0dfcf9d050ff6e_4]**
