Question 1

What is Tremfya?

Accepted Answer

Tremfya is a biologic medication classified as an interleukin-23 (IL-23) blocker. It is designed to bind to IL-23, a naturally occurring protein that plays a key role in the body's inflammatory and immune responses.

By inhibiting this protein, the medication helps to decrease overactive immune signaling. This targeted approach helps manage the underlying biological processes associated with certain inflammatory conditions.

Question 2

What is Tremfya used for?

Accepted Answer

Tremfya is used to treat plaque psoriasis and psoriatic arthritis .

Question 3

How does Tremfya work?

Accepted Answer

Mechanism of Action

Tremfya belongs to a class of medications known as interleukin-23 (IL-23) blockers. It is a human monoclonal antibody designed to target and bind to a specific protein called IL-23.

In people with conditions like plaque psoriasis or psoriatic arthritis, the immune system produces too much IL-23. This excess protein triggers an inflammatory response that leads to:

Rapid overgrowth of skin cells, resulting in thick, scaly plaques.

Inflammation in the joints, causing pain and swelling.

By binding to the p19 subunit of the IL-23 protein, Tremfya prevents it from interacting with its receptors on the surface of immune cells. This action helps to normalize the immune response and reduce the inflammation that causes symptoms.

Question 4

What are the active ingredients in Tremfya?

Accepted Answer

The active ingredient in Tremfya is guselkumab .

Question 5

What are the side effects of Tremfya?

Accepted Answer

Common side effects of Tremfya may include:

upper respiratory tract infection

headache

injection site reactions

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Tremfya?

Accepted Answer

Tremfya belongs to the IL-23 inhibitor drug class.

Question 7

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

Accepted Answer

How Tremfya is Administered

Tremfya is given as a subcutaneous injection, which means it is injected into the fatty tissue just under the skin. It is commonly injected into the front of the thighs, the lower abdomen, or the back of the upper arms. A healthcare professional may give the first few doses. After receiving proper training, you or a caregiver may be able to perform the injections at home using a prefilled syringe or an autoinjector device.

Preparation and Use

Remove the medication from the refrigerator and let it reach room temperature for 30 minutes before injecting.

Do not shake the syringe or autoinjector.

Choose a different injection site each time you use the medication. Avoid areas where the skin is tender, bruised, red, hard, or affected by psoriasis.

Each prefilled syringe or autoinjector is for single use only and should be disposed of in a puncture-resistant sharps container.

Missed Doses

If you miss a dose of Tremfya, use it as soon as you remember. After that, continue with your next dose at the regularly scheduled time. Do not use extra medicine to make up for a missed dose.

Question 8

Is Tremfya safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There is limited research on the use of Tremfya in pregnant women. While animal studies did not show direct harm to the fetus at high doses, monoclonal antibodies like Tremfya are known to cross the placenta, especially during the third trimester. This could potentially affect the immune system of the newborn.

If you are pregnant or planning to become pregnant, discuss the potential risks and benefits with your healthcare provider. They can help determine if the treatment is appropriate for your situation.

Breastfeeding

It is not known if Tremfya passes into human breast milk or if it could affect a nursing infant. Because many drugs can be present in breast milk, you should consult with your doctor to determine if you should continue breastfeeding while using this medication. Decisions should consider the health benefits of breastfeeding alongside the mother's clinical need for the drug.

Question 9

What forms and strengths does Tremfya come in?

Accepted Answer

Tremfya is supplied in the following delivery formats:

Subcutaneous Injection: This form is available as a prefilled syringe or a patient-controlled injector for administration under the skin.

Intravenous Infusion: This form is administered by a healthcare professional directly into a vein.

Question 10

What is the FDA approval status of Tremfya?

Accepted Answer

FDA Approval History

Tremfya (guselkumab) was first approved by the U.S. Food and Drug Administration (FDA) in July 2017. It was the first approved treatment that selectively blocks interleukin-23 (IL-23), a protein that plays a role in inflammatory and immune responses.

Approved Indications

The FDA has approved Tremfya for the treatment of the following conditions in adult patients:

Plaque Psoriasis: For those with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy.

Psoriatic Arthritis: For the treatment of active psoriatic arthritis.

Ulcerative Colitis: For the treatment of moderately to severely active ulcerative colitis.

Regulatory Status and Safety

There are currently no Boxed Warnings or Risk Evaluation and Mitigation Strategy (REMS) programs required by the FDA for Tremfya. However, regulatory guidelines require that patients be evaluated for tuberculosis infection prior to starting treatment, as the medication can affect the immune system's ability to fight infections.

Question 11

What should I know about Tremfya and cost?

Accepted Answer

Factors Affecting Price

Tremfya is a biologic medication, and these types of drugs generally have a higher cost than standard medications. The amount you pay out of pocket will depend on several factors, including:

Your specific health insurance plan and its list of covered drugs (formulary).

Your remaining annual deductible and your required copayment or coinsurance.

Whether the medication is administered by a healthcare professional in a clinic or self-injected at home.

Financial Assistance and Savings

Many patients do not pay the full list price for Tremfya due to various assistance options. These may include:

Manufacturer Savings Cards: Patients with commercial or private insurance may qualify for a savings card that significantly reduces the cost of each dose.

Patient Assistance Programs: For individuals who are uninsured or underinsured, the manufacturer or independent non-profit organizations may offer programs to provide the medication at a reduced cost or for free, depending on financial need.

Insurance and Medicare Coverage

Most private insurance plans provide coverage for Tremfya, though they often require prior authorization. This means your doctor must provide documentation to the insurance company explaining why the medication is medically necessary before they will agree to pay for it. Medicare and Medicaid coverage varies depending on the specific plan and state regulations. In some instances, Tremfya may be covered under your medical benefit rather than your pharmacy benefit if it is administered in a doctor's office.
