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.

Sixty years ago, Medicaid and Medicare were established when President Lyndon B. Johnson signed the Social Security Amendments into law. The programs were a larger part of Johnson's "War on Poverty" agenda to combat inequality. Sixty years later, Medicaid and Medicare are under attack in ways that we could never have imagined. With the passage of the One Big Beautiful Bill Act (OBBBA), $1 trillion was cut from Medicaid and Medicare―the largest health care cut in U.S. history. As a result of the budget package, more than 15 million people will lose health insurance, hundreds of rural hospitals will close, and approximately 51,000 people will die preventable deaths each year. Congress voted for this harm, and Congress can fix it. We need them to invest in Medicaid and Medicare in order to undo this damage. Click here to send a message to Congress telling them to invest in these critical programs, not cut them. OBBBA is the exact opposite of the "War on Poverty." The bill was passed with brutal cuts to health care to fund more tax handouts for the very wealthy. It took from the poor to give to the rich. The unpopularity of these cuts cannot be overstated. Eighty-three percent of the American public, including three in four Republicans, has a favorable view of Medicaid. Congress must hear from us loud and clear: reverse course, undo the harm to Medicaid and Medicare, and protect health care for more than 71 million people. Join us in sending the message to Congress to invest in these critical programs, don't cut them. 1 The Truth About the One Big Beautiful Bill Act’s Cuts to Medicaid and Medicare 2 Research Memo: Projected Mortality Impacts of the Budget Reconciliation Bill 3 Medicaid keeps getting more popular as Republicans aim to cut it by $800 billion
