Question 1

What is Nucala?

Accepted Answer

Nucala is a monoclonal antibody that functions by targeting interleukin-5, a signaling protein in the immune system. This protein is primarily responsible for the growth, activation, and survival of eosinophils, which are a specific type of white blood cell.

By binding to interleukin-5, the medication prevents it from attaching to its receptors, thereby reducing the number of eosinophils circulating in the body. This mechanism helps to control inflammation associated with high eosinophil levels.

Question 2

What is Nucala used for?

Accepted Answer

Nucala is used to treat:

Severe eosinophilic asthma

Eosinophilic granulomatosis with polyangiitis

Hypereosinophilic syndrome

And others

Question 3

How does Nucala work?

Accepted Answer

Targeting Inflammation

Nucala (mepolizumab) belongs to a class of medications called monoclonal antibodies. It is specifically designed to target and bind to a protein in the body called interleukin-5 (IL-5).

The Role of IL-5 and Eosinophils

IL-5 is a signaling molecule that plays a key role in the growth, activation, and survival of eosinophils. Eosinophils are a type of white blood cell that helps the immune system fight off certain infections. However, in people with certain conditions, the body produces too many eosinophils or they become overactive.

High levels of eosinophils can lead to significant inflammation in various parts of the body, including:

The lungs and airways (in severe asthma)

The nasal passages (in chronic rhinosinusitis with nasal polyps)

The blood vessels (in eosinophilic granulomatosis with polyangiitis)

The blood and organs (in hypereosinophilic syndrome)

How Nucala Reduces Symptoms

Nucala works by attaching itself to the IL-5 protein. By doing this, it prevents IL-5 from binding to the receptors on the surface of eosinophils. Without the IL-5 signal, the production and survival of these cells are significantly reduced.

By lowering the number of eosinophils in the blood and tissues, Nucala helps decrease the underlying inflammation. This can lead to fewer flare-ups, improved breathing, and a reduction in other symptoms associated with high eosinophil levels.

Question 4

What are the active ingredients in Nucala?

Accepted Answer

The active ingredient in Nucala is mepolizumab .

Question 5

What are the side effects of Nucala?

Accepted Answer

Common side effects of Nucala may include:

headache

injection site reactions

back pain

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Nucala?

Accepted Answer

Nucala belongs to the IL-5 antagonist monoclonal antibody drug class.

Question 7

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

Accepted Answer

Administration Method

Nucala is given as a subcutaneous injection, which is an injection into the fatty tissue just beneath the skin. It is typically administered once every four weeks.

Where to Inject

The injection is usually given in the following areas:

The front of the thighs

The abdomen (avoiding the area immediately around the belly button)

The outer area of the upper arm (only if administered by a caregiver or healthcare provider)

Self-Administration at Home

Depending on the specific device prescribed, Nucala may be administered by a healthcare provider in a clinic or self-injected at home using a prefilled autoinjector or prefilled syringe. Before using the medication at home, a healthcare professional must provide training on the correct way to prepare and inject the dose. It is important to allow the medication to sit at room temperature for a short period before use and to never shake the syringe or autoinjector.

Missed Doses

If a dose is missed, it should be taken as soon as it is remembered. After that, the regular four-week schedule should be resumed. Do not take an extra dose or multiple doses at once to make up for a missed one.

Question 8

Is Nucala safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Data on the use of Nucala in pregnant women are insufficient to determine if there is a drug-associated risk for major birth defects, miscarriage, or other adverse outcomes. In animal studies, no evidence of fetal harm was observed in monkeys given mepolizumab at doses significantly higher than the recommended human dose.

Mepolizumab is a monoclonal antibody. These types of proteins are known to cross the placenta, with the amount transferred increasing during the third trimester. Therefore, any potential effects on the fetus are most likely to occur during the later stages of pregnancy.

A pregnancy exposure registry has been established to monitor the health of individuals who use Nucala while pregnant. Healthcare providers may encourage patients to enroll in this registry to help collect more data on the drug's safety during pregnancy.

Breastfeeding

It is not known whether Nucala is present in human breast milk, how it affects milk production, or what effects it may have on a breastfed infant. Because Nucala is a large protein molecule, it is thought that the amount absorbed by a nursing infant would be low.

The decision to use Nucala while breastfeeding should involve a discussion with a healthcare provider. Factors to consider include the mother's clinical need for the medication, the health benefits of breastfeeding for the infant, and any potential adverse effects on the child.

Question 9

What forms and strengths does Nucala come in?

Accepted Answer

Nucala is administered as a subcutaneous injection. It is available in the following forms:

Prefilled autoinjector: A single-dose device used to deliver the medication under the skin.

Prefilled syringe: A single-dose syringe used for subcutaneous administration.

Vial: A single-dose vial containing a lyophilized powder that must be mixed with a liquid before injection.

Question 10

What is the FDA approval status of Nucala?

Accepted Answer

FDA Approval and Indications

Nucala (mepolizumab) is approved by the U.S. Food and Drug Administration (FDA) as an interleukin-5 (IL-5) antagonist monoclonal antibody. It works by reducing the levels of eosinophils, which are white blood cells that contribute to inflammation in various diseases.

The FDA has approved Nucala for the following specific uses:

Severe Eosinophilic Asthma: As an add-on maintenance treatment for patients aged 6 years and older.

Chronic Rhinosinusitis with Nasal Polyps (CRSwNP): As an add-on maintenance treatment for adults who do not respond adequately to nasal corticosteroids.

Eosinophilic Granulomatosis with Polyangiitis (EGPA): For the treatment of adult patients with this rare condition.

Hypereosinophilic Syndrome (HES): For adults and pediatric patients aged 12 years and older who have had the condition for at least six months without a known non-hematologic cause.

Regulatory Status and Safety

Nucala is available only with a prescription from a healthcare provider. It is administered via subcutaneous injection. The FDA has not approved Nucala for the treatment of other eosinophilic conditions or for the relief of acute bronchospasm (sudden breathing problems).

There are currently no boxed warnings or Risk Evaluation and Mitigation Strategy (REMS) requirements associated with Nucala. It is intended for long-term maintenance rather than emergency use.

Question 11

What should I know about Nucala and cost?

Accepted Answer

Factors Influencing Cost

The actual price you pay for Nucala can vary significantly based on several variables:

Insurance Coverage: Your specific health insurance plan, including your deductible and copay or coinsurance requirements, will determine your out-of-pocket expenses.

Administration Method: Nucala is available as a prefilled syringe or autoinjector for self-administration, or as a vial that a healthcare professional must administer. Costs may differ depending on whether the drug is billed through your pharmacy benefit or medical benefit.

Specialty Pharmacy: As a biologic medication, Nucala is often classified as a specialty drug. It may only be available through specific specialty pharmacies, which can influence the final price.

Financial Assistance

There are options available that may help reduce the cost of Nucala for eligible patients:

Copay Savings Programs: Patients with commercial insurance may be eligible for manufacturer copay cards to help lower their monthly costs.

Patient Assistance Programs: For individuals who are uninsured or underinsured, programs may exist to provide the medication at a reduced cost or for free, based on financial need and eligibility criteria.

Because Nucala is a long-term maintenance treatment, it is important to verify coverage with your insurance provider and discuss potential financial assistance options with your healthcare team or the manufacturer's support services.
