Cytokinetics' (CYTK) Aficamten Gets Breakthrough Therapy Tag

In this article:

Cytokinetics, Incorporated CYTK announced that the FDA has granted a Breakthrough Therapy designation to its investigational candidate, aficamten, for the treatment of symptomatic obstructive hypertrophic cardiomyopathy (oHCM).

The Breakthrough Therapy designation is granted to medicines being evaluated for serious conditions where early clinical evidence indicates the potential for substantial improvement using available therapy.

The above-mentioned Breakthrough Therapy designation was granted based on data from the cohorts 1 and 2 of the phase II REDWOOD-HCM study that evaluated aficamten in patients with symptomatic oHCM.

Data from the same showed that treatment with aficamten for 10 weeks led to statistically significant reductions from baseline in the average resting left ventricular outflow tract pressure gradient (LVOT-G) and the average post-Valsalva LVOT-G versus placebo. Also, patients treated with aficamten experienced improvements in their heart failure symptoms. Treatment with aficamten was generally well tolerated.

The company has also completed enrollment in the cohort 3 of the REDWOOD-HCM study for patients whose background therapy includes disopyramide. Data from this cohort is expected in the first quarter of 2022.

Shares of Cytokinetics have skyrocketed 68.6% so far this year against the industry’s decrease of 19.6%.

We note that aficamten, a next-generation cardiac myosin inhibitor, is being developed for the potential treatment of HCM. The company is preparing the start-up activities for another phase III study – SEQUOIA-HCM – evaluating aficamten in patients with symptomatic oHCM.

Cytokinetics is developing its lead drug candidate, omecamtiv mecarbil, a cardiac myosin activator, for treating patients with heart failure.

Based on positive data from the phase III GALACTIC-HF study, the company is planning to submit a new drug application for omecamtiv mecarbil in the United States shortly.
