US FDA Updates Camzyos Label for oHCM

U.S. Food and Drug Administration Updates CAMZYOS® (mavacamten) Label to Reduce Echocardiography Monitoring Requirements and Contraindications for Obstructive HCM

Label updates include simplified twice-yearly echo monitoring for eligible CAMZYOS patients in the maintenance phase and expanded patient eligibility with reduced contraindications

Updated U.S. label is supported by data including long-term clinical and real-world evidence which reinforce the strong safety profile of CAMZYOS.


“In addition to the established efficacy of CAMZYOS, these meaningful updates to the label reinforce the strong safety profile of the therapy. With robust clinical and real-world data and more than 15,000 patients prescribed CAMZYOS in the U.S.,2 this medicine has redefined the treatment landscape for symptomatic obstructive HCM and can have a significant impact for patients living with the condition,” said Al Reba, senior vice president, Cardiovascular & Immunology Commercialization at Bristol Myers Squibb. “Simplifying treatment by reducing the frequency of echo monitoring not only improves the patient experience, but will also save time for cardiologists, allowing them to treat more patients.”

The approved label update is supported by long-term clinical and real-world data, including analyses of results from the CAMZYOS Risk Evaluation and Mitigation Strategy (REMS) Program, real-world experience from three single-center studies, and ongoing clinical data reinforcing the safety profile of CAMZYOS through 3.5 years.

Medical Management means using medicines and other non-invasive therapies to relieve symptoms. It's exciting that new treatments for HCM are being studied and that the FDA approved Camzyos in 2022! HCM can cause various symptoms depending on how stiff the heart is, how much scarring (fibrosis) there is, and whether there is obstruction. Some people have no noticeable symptoms. Common symptoms are chest pain/pressure, shortness of breath, lightheadedness, fatigue, palpitations, and brain fog. Syncope (fainting) is dramatic but not as common as the other symptoms. Medications are the first-line treatment for symptoms of HCM. If patients can't take one class of medication, they can try a medication from a different class. Here are some medications used to treat HCM and what they're for: Beta Blockers - make your heart beat slower and relax better. They allow the heart to fill more completely between beats. They can lower blood pressure and relieve symptoms. Calcium Channel Blockers - used to lower blood pressure and slow the heart rate. May reduce symptoms from obstruction in HCM. Myosin Inhibitors - cause the heart to beat with less force. They may reduce obstruction and septal thickness in some patients. Camzyos (mavacamten) is the first of this class of medication. For more information, click HERE . Antiarrhythmics - help to restore normal rhythm in the heart. Blood Thinners - anticoagulants and anti-platelets make it harder for blood to clot. They are prescribed to reduce the risk of stroke. This risk is higher in patients with afib, aflutter, and artificial heart valves. Diuretics , or "water pills," help the kidneys get rid of extra water and salt, reducing swelling in the body. Sodium Channel Blockers - may reduce gradient in obstructive HCM and can treat chest pain. Some also act as antiarrhythmics. Antibiotics - treat or prevent bacterial infections. In HCM, they may be given before dental work to prevent infective endocarditis. To learn more and see the side effects of these medications, click HERE .
