CAMZYOS® MAY HELP
YOU GET BACK TO THE
ACTIVITIES YOU LOVE

CAMZYOS is only approved for patients 18 and older.

If you're still short of breath or feeling tired on your current oHCM medication, you deserve the possibility of symptom improvement. In clinical studies, CAMZYOS not only improved symptoms* but also improved the ability to be more active again. Ask your cardiologist about CAMZYOS.

Clinical Study Results

image-horizontal-rule-1

CAMZYOS is being studied in the longest clinical study for a treatment of its kind.

cl

There are limitations to the long-term study. These data are not included in the CAMZYOS U.S. Full Prescribing Information. These data are based on real observations as part of an ongoing study. These data have not yet been tested to determine if results are based on real effect or random chance. All participants knew they were taking CAMZYOS, which may have influenced the results.

*Symptoms were measured using the New York Heart Association (NYHA) classification.
The ability to be active was determined by measuring peak oxygen the body consumes during exercise. This was measured during exercise testing on a bicycle or treadmill.
CAMZYOS is a cardiac myosin inhibitor.
§Though it wasn't a requirement of the study, most of the participants remained on their previous medication, a beta blocker or calcium channel blocker.
||The primary goal of the long-term study was to evaluate safety and efficacy.
Amongst the efficacy outcomes, a range of 90 to 95 patients to date (of 231) have reached Week 180 for evaluation.

The study first looked at how many people experienced either:

Some improvementin their ability to be active and an improvement in their symptoms

OR

image-horizontal-rule-2
More improvement# in their ability to be active and no worsening of their symptoms
image-horizontal-rule-2

Results showed that more people taking CAMZYOS achieved this outcome (37%, 45/123) compared with those taking placebo (17%, 22/128).

#Some improvement=improved pVO2 by at least 1.5 mL/kg/min. More improvement=improved pVO2 by at least 3.0 mL/kg/min.

CAMZYOS will not work for everyone. Individual results may vary.

Surgery Eligible

image-horizontal-rule-1

CAMZYOS reduced the number of patients who were eligible for, or who chose to undergo, surgery at 16 weeks (avoiding surgery)

A 16-week study of 112 people compared two groups of adults with symptomatic obstructive HCM. One group (56 people) took CAMZYOS while the other group (56 people) took a placebo. When the study started, everyone had symptoms. Some (7%) had moderate symptoms (NYHA Class II), but most (93%) had severe symptoms (NYHA Class III or IV). Everyone’s obstructive HCM was so advanced that they were eligible for heart surgery.

WHAT THE STUDY RESULTS SHOWED

image-horizontal-rule-2
The study looked at how many people either:

Remained eligible for surgery at Week 16 

OR

Decided to proceed with surgery prior to or at Week 16 

Results showed that CAMZYOS reduced the proportion of patients who were eligible for, or who chose to undergo, surgery. 18% of people taking CAMZYOS (~1 out of 5) and 77% of people taking placebo (~4 out of 5) remained eligible for surgery at 16 weeks or chose to undergo surgery prior to or at Week 16. Two people in each group decided to have surgery.

#No longer eligible and did not choose to undergo surgery at Week 16.

Most people in this study (95%) were also taking additional treatments for their HCM such as a beta blocker, calcium channel blocker, disopyramide, or a combination of these.

CAMZYOS will not work for everyone. Individual results may vary.

serious side effect is a side effect that can sometimes be life-threatening and lead to death.

CAMZYOS may cause serious side effects, including heart failure (a condition where the heart cannot pump with enough force).

In the long-term study, 10 (4.3%) people in the study experienced drug-related serious adverse events, which included cardiac failure (n=3), ejection fraction decreased (n=5), atrial fibrillation (n=1), and atrial flutter (n=1).

Get medical help right away if you experience new or worsening symptoms, including:

  • Shortness of breath

  • Chest pain

  • Fatigue

  • Racing heart (palpitations)

In the long-term study, 228 (98.7%) people experienced ≥1 drug-related adverse reaction. The most common drug-related adverse reaction occurring in >5% of people were COVID-19 infection (n=92), dizziness, (n=41), hypertension (n=36), and nasopharyngitis (n=36).

  • Tell your healthcare provider if you have any side effect that bothers you or that does not go away

Some important safety information to know is: CAMZYOS® (mavacamten) may cause serious side effects, including heart failure, a condition where the heart cannot pump with enough force. Heart failure is a serious condition that can lead to death. You must have echocardiograms before you take your first dose and during your treatment with CAMZYOS to help your healthcare provider understand how your heart is responding to CAMZYOS. People who develop a serious infection or irregular heartbeat have a greater risk of heart failure during treatment with CAMZYOS. Tell your healthcare provider or get medical help right away if you develop new or worsening shortness of breath, chest pain, fatigue, swelling in your legs, or a racing sensation in your heart (palpitations) or rapid weight gain.
