Question 1

What is Zilbrysq?

Accepted Answer

Zilbrysq is a synthetic peptide that functions as a complement inhibitor. It works by binding to the C5 protein, a key component of the immune system's complement cascade. By blocking this protein, the medication prevents the activation of certain immune responses that can lead to tissue damage.

This targeted approach helps manage the biological processes associated with immune-mediated conditions. By interfering with the complement system, the medication helps control the underlying mechanism that causes the body to attack its own cells.

Question 2

What is Zilbrysq used for?

Accepted Answer

Zilbrysq is used to treat myasthenia gravis .

Question 3

How does Zilbrysq work?

Accepted Answer

Mechanism of Action

Zilbrysq (zilucoplan) is used to treat generalized myasthenia gravis (gMG) in adults. It belongs to a class of drugs known as complement inhibitors. In people with gMG, the immune system mistakenly attacks the neuromuscular junction, which is the area where nerve cells communicate with muscle cells.

The medication works by targeting the complement system, a group of proteins in the blood that are part of the body's natural immune defense. In gMG, this system becomes overactive and damages the surface of muscle cells, leading to weakness and fatigue.

Zilbrysq works through the following steps:

Binding to C5: The drug binds specifically to a protein called complement component 5 (C5).

Blocking Activation: By binding to C5, Zilbrysq prevents it from being broken down into smaller proteins (C5a and C5b) that would normally trigger further immune destruction.

Preventing Muscle Damage: This action stops the formation of the membrane attack complex (MAC), which is the final step in the complement process that causes physical damage to the muscle membrane.

By inhibiting this specific part of the immune response, Zilbrysq helps protect the connection between nerves and muscles. This allows signals from the nervous system to reach the muscles more effectively, which can improve muscle strength and physical function.

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Zilbrysq?

Accepted Answer

Question 7

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

Accepted Answer

How to Use Zilbrysq

Zilbrysq is administered as a subcutaneous injection into the fatty tissue under the skin. It is typically used once daily at the same time each day. A healthcare provider will provide training on how to prepare and inject the medication so that you or a caregiver can administer it at home.

Injection Sites

Common areas for injection include the abdomen, the front of the thighs, or the back of the upper arms. It is important to rotate the injection site with every dose. Avoid injecting into areas where the skin is tender, bruised, red, hard, or has scars or stretch marks.

Preparation

Remove the prefilled syringe from the refrigerator and let it sit at room temperature for approximately 30 minutes before injecting. Do not use a microwave or hot water to warm the syringe.

Inspect the medicine before use. The liquid should be clear to slightly yellow and free of large particles.

Do not shake the syringe.

Missed Dose

If you miss a dose, 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 return to your regular schedule. Do not inject two doses at the same time to make up for a missed dose.

Question 8

Is Zilbrysq safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

It is not currently known if Zilbrysq will harm an unborn baby. There have not been enough studies in pregnant humans to determine if the medication is safe to use during pregnancy. If you are pregnant or planning to become pregnant, talk with your healthcare provider about the potential risks and benefits of continuing treatment.

Breastfeeding

It is unknown whether Zilbrysq passes into breast milk or if it could affect a nursing child. Because it is not known how the drug might impact a breastfed infant, you should discuss your options with your doctor. They can help you decide on the safest way to feed your baby while you are using this medication.

Question 9

What forms and strengths does Zilbrysq come in?

Accepted Answer

Zilbrysq is available as a solution for subcutaneous injection. It is provided in single-dose prefilled syringes.

This medication is intended for self-injection after a healthcare professional has provided proper training on how to prepare and inject the dose. Each prefilled syringe is used once and then discarded.

Question 10

What is the FDA approval status of Zilbrysq?

Accepted Answer

FDA Approval and Indications

Zilbrysq (zilucoplan) was approved by the U.S. Food and Drug Administration (FDA) in 2023. It is specifically approved for the treatment of generalized myasthenia gravis (gMG) in adult patients who test positive for anti-acetylcholine receptor (AChR) antibodies.

Boxed Warning

Zilbrysq carries a boxed warning, the FDA’s most serious warning, regarding the risk of life-threatening meningococcal infections. These infections can progress rapidly and may be fatal if not identified and treated immediately. To mitigate this risk, patients must be vaccinated against meningococcal disease at least two weeks before starting the medication. If treatment must start sooner, healthcare providers must prescribe preventive antibiotics.

REMS Program

Because of the risk of serious infection, Zilbrysq is only available through a restricted program called the Zilbrysq Risk Evaluation and Mitigation Strategy (REMS). This program requires:

Healthcare providers to be certified and to counsel patients on the risks of infection.

Patients to be enrolled in the program and carry a patient safety card at all times.

Pharmacies to be certified to dispense the medication.

Question 11

What should I know about Zilbrysq and cost?

Accepted Answer

Factors Influencing Cost

The actual price you pay for Zilbrysq can vary based on several factors, including:

Insurance Coverage: Your out-of-pocket expenses will depend on your specific health insurance plan, including your deductible, copayment, or coinsurance requirements.

Specialty Pharmacy: Zilbrysq is a specialty medication and is typically dispensed through specialty pharmacies rather than standard retail pharmacies, which can affect the final price.

Dosage: The specific dose and frequency of administration prescribed by your doctor may influence the total cost of treatment.

Generic Availability

Zilbrysq is a brand-name medication. Currently, there is no generic version of zilucoplan available. Brand-name drugs generally have a higher cost than generic alternatives.

Financial Assistance Programs

The manufacturer may offer support programs to help manage the cost of Zilbrysq. These may include copay savings cards for patients with commercial insurance or patient assistance programs for those who are uninsured or underinsured. You can speak with your healthcare provider or pharmacist to find out if you qualify for these programs.
