Question 1

What is Camzyos?

Accepted Answer

Camzyos is a medication classified as a cardiac myosin inhibitor. It works by targeting the underlying mechanical process of heart muscle contraction to help the heart relax more effectively.

By modulating the activity of specific proteins within the heart, the medication helps reduce excessive muscle tension. This action is intended to improve the heart's overall function and support better blood flow through the heart chambers.

Question 2

What is Camzyos used for?

Accepted Answer

Camzyos is used to treat hypertrophic cardiomyopathy .

Question 3

How does Camzyos work?

Accepted Answer

Targeting Heart Muscle Proteins

Camzyos belongs to a class of medications called cardiac myosin inhibitors. It is specifically designed to treat obstructive hypertrophic cardiomyopathy (oHCM), a condition where the heart muscle becomes thickened and overactive.

In a healthy heart, proteins called myosin and actin work together to make the heart muscle contract. In people with oHCM, these proteins create too many connections, known as cross-bridges. This causes the heart to contract with too much force and prevents it from relaxing properly between beats.

Improving Heart Function

Camzyos works by binding to the myosin proteins to reduce the number of active cross-bridges. This process leads to several key changes in how the heart functions:

Reduced Contraction Force: By limiting the number of connections between muscle proteins, the medication prevents the heart from squeezing too hard.

Better Relaxation: The heart muscle can relax more easily, which allows the heart chambers to fill with more blood.

Decreased Obstruction: Reducing the force of contraction helps clear the path for blood to flow out of the heart and into the rest of the body.

By addressing the underlying cause of the overactive heart muscle, Camzyos helps improve the heart's efficiency and reduces symptoms associated with the condition.

Question 4

What are the active ingredients in Camzyos?

Accepted Answer

The active ingredient in Camzyos is mavacamten .

Question 5

What are the side effects of Camzyos?

Accepted Answer

Common side effects of Camzyos may include:

Dizziness

Fatigue

Shortness of breath

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Camzyos?

Accepted Answer

Camzyos belongs to the cardiac myosin inhibitor drug class.

Question 7

What is the dosage of Camzyos and how do I take it?

Accepted Answer

How to Take Camzyos

Camzyos is a capsule that is taken by mouth once a day. It should be swallowed whole and should not be crushed, chewed, or opened. You may take this medication with or without food, but it is best to take it at the same time each day.

Monitoring and Dose Adjustments

Because this medication affects how the heart pumps blood, your healthcare provider will require regular heart imaging tests, such as echocardiograms. These tests are used to monitor your heart's response to the medication and to determine if your dose needs to be adjusted or if treatment should be temporarily paused.

Missed Dose

If you miss a dose of Camzyos, take it as soon as you remember on the same day. If you do not remember until the next day, skip the missed dose and take your next dose at the regular time. Do not take two doses at once to make up for a missed dose.

Question 8

Is Camzyos safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Based on animal studies, Camzyos may cause fetal harm and birth defects when used during pregnancy. There is limited data on its effects in humans, so it is generally avoided unless the potential benefit justifies the risk to the fetus.

Individuals who can become pregnant should confirm they are not pregnant before starting this medication. Effective contraception is required during treatment and for 4 months after the last dose. Because Camzyos can interact with and reduce the effectiveness of some hormonal contraceptives, healthcare providers may recommend using non-hormonal birth control or specific combinations of methods.

Breastfeeding

It is not known if Camzyos passes into breast milk or if it could harm a nursing infant. Because of the potential for serious adverse reactions, breastfeeding is usually not recommended during treatment. Patients should discuss infant feeding options with their healthcare provider to determine the safest course of action.

Question 9

What forms and strengths does Camzyos come in?

Accepted Answer

Camzyos is supplied in the following form:

Oral Capsule: This medication is taken by mouth, typically once per day.

The medication is available in several different strengths. A healthcare provider will determine the appropriate strength for each patient and may adjust it over time based on the results of heart function monitoring.

Question 10

What is the FDA approval status of Camzyos?

Accepted Answer

FDA Approval and Indication

The U.S. Food and Drug Administration (FDA) approved Camzyos in April 2022. It is indicated for the treatment of adults with symptomatic obstructive hypertrophic cardiomyopathy (oHCM) who have New York Heart Association (NYHA) class II-III symptoms. The medication is designed to improve physical capacity and reduce the severity of symptoms in these patients.

Boxed Warning

Camzyos carries a Boxed Warning regarding the risk of heart failure. The drug reduces the left ventricular ejection fraction (LVEF), which is a measurement of how much blood the heart pumps out with each contraction. If LVEF becomes too low, it can lead to heart failure due to systolic dysfunction. Because of this risk, patients must have their LVEF measured by echocardiogram before starting the medication and at regular intervals during treatment.

REMS Program

Due to the risk of heart failure, Camzyos is only available through a restricted distribution program called the CAMZYOS Risk Evaluation and Mitigation Strategy (REMS). The requirements of this program include:

Prescribers must be certified by enrolling in the REMS program.

Pharmacies must be certified and only dispense the medication to authorized patients.

Patients must be enrolled in the program and comply with the required heart monitoring (echocardiograms).

Drug Interactions

The FDA warns that Camzyos can interact with many other medications, including certain over-the-counter drugs and herbal supplements. These interactions can increase the concentration of Camzyos in the body, raising the risk of heart failure, or decrease its concentration, making it less effective. It is contraindicated for use with certain strong cytochrome P450 inhibitors or inducers.

Question 11

What should I know about Camzyos and cost?

Accepted Answer

The price of Camzyos can vary based on several factors, including your insurance plan's formulary and the specialty pharmacy used to fill the prescription. Because Camzyos is a brand-name medication and there is currently no generic version available, the cost may be higher than other heart medications.

Insurance Coverage

Many insurance plans, including private insurance and Medicare, may cover Camzyos, but the out-of-pocket costs like copays or coinsurance will depend on your specific plan. Because this drug is only available through a restricted program called the Camzyos REMS, it must be dispensed by a certified specialty pharmacy rather than a standard retail pharmacy.

Financial Assistance

The manufacturer of Camzyos may offer financial support programs to help reduce the cost for eligible patients. These programs often include copay cards for individuals with commercial insurance or patient assistance programs for those who are uninsured or underinsured. Patients are encouraged to discuss these options with their healthcare provider or the specialty pharmacy handling their prescription.

Generic Availability

There is currently no generic version of mavacamten (the active ingredient in Camzyos). Brand-name drugs typically have higher costs because they are protected by patents that prevent other companies from making generic versions for a set period of time.
