European Medicines Agency approves Bristol Myers Squibb’s request for Mavacamten for the treatment of hypertrophic obstructive cardiomyopathy | Business


PRINCETON, NJ – (BUSINESS WIRE) – October 1, 2021–

Bristol Myers Squibb (NYSE: BMY) today announced that the European Medicines Agency (EMA) has validated its Marketing Authorization Application (MAA) for mavacamten, a leading experimental cardiac myosin inhibitor class, intended for the treatment of patients with obstructive hypertrophy cardiomyopathy (obstructive HCM). The validation of the application confirms that the submission is complete and that the centralized procedure of the EMA with the evaluation of the Committee for Medicinal Products for Human Use (CHMP) begins.

“Despite the global prevalence of obstructive CMH, its debilitating symptoms and cardiac dysfunction, there is as yet no approved treatment that targets the underlying cause of this devastating disease. Most of the medications currently prescribed only relieve symptoms. Mavacamten could potentially provide a treatment option that addresses the unmet needs of people living with obstructive HCM worldwide, ”said Roland Chen, MD, senior vice president, Cardiovascular Development, Bristol Myers Squibb. “Today’s acceptance of the dossier by the EMA is a step forward in bringing this important targeted therapeutic approach to patients and physicians in Europe, and we thank the patients and researchers who were involved in the EXPLORER trial -HCM.

The request is based on the results of the pivotal phase 3 EXPLORER-HCM trial, which evaluated mavacamten in patients with symptomatic obstructive HCM versus placebo. The results of the trial showed that the mavacamten demonstrated a clear therapeutic effect, with clinically significant improvements in symptoms, functional status and quality of life, as well as the ability to relieve obstruction of the pathway. left ventricular ejection. In the EXPLORER-HCM study, all primary and secondary endpoints were met with statistical significance.

About the EXPLORER-HCM Phase 3 trial

The Phase 3 EXPLORER-HCM trial enrolled a total of 251 patients with symptomatic obstructive hypertrophic cardiomyopathy (NYHA class II or III). All participants had a measurable left ventricular outflow pathway (LVOT) gradient (at rest and / or provoked) ≥50 mmHg at baseline.

The primary endpoint for EXPLORER-HCM was a composite functional analysis designed to capture the effect of mavacamten on symptoms and function. Secondary endpoints were changes from baseline at week 30 in post-exercise LVOT gradient, pVO2, proportion of patients with at least NYHA class improvement, and measurements of patient-reported results. Additional endpoints included changes from baseline at week 30 in echocardiographic indices, circulating biomarkers, heart rhythm patterns, and accelerometry.

About Obstructive Hypertrophic Cardiomyopathy

Obstructive Hypertrophic Cardiomyopathy (Obstructive HCM), the most common type of HCM, is a chronic, progressive disease in which the heart muscle becomes abnormally enlarged or thick, causing obstruction of the left ventricular outflow tract (LVOT) where blood leaves the heart to become blocked by enlarged heart muscle. As a result, obstructive HCM can lead to debilitating symptoms for patients and has also been associated with increased risks of atrial fibrillation, stroke, heart failure, and sudden cardiac death.

The most common cause of obstructive HCM is mutations in sarcomere heart muscle proteins and up to 50% of patients have an inherited predisposition to the disease. Obstructive HCM is estimated to affect 400,000 to 600,000 people worldwide, but many patients remain undiagnosed and / or asymptomatic.

About Mavacamten

Mavacamten is a first-class oral allosteric modulator of cardiac myosin being investigated for the treatment of conditions caused by excessive cardiac contractility and impaired diastolic filling of the heart, including hypertrophic cardiomyopathy (HCM) and heart failure. with preserved ejection fraction (HFpEF).

In clinical studies, mavacamten has been shown to be significantly effective in reducing cardiac muscle contractility by reducing excess actin-myosin crossbridges, leading to less hypercontractility and better relaxation.

In obstructive HCM in particular, it is the first and only selective cardiac myosin inhibitor that has the potential to address the underlying pathophysiology of the disease.

Mavacamten is an investigational treatment and it is not approved for use in any country.
