Vyvgart (efgartigimod alfa-fcab) is a prescription drug used to treat myasthenia gravis in certain adults. Vyvgart’s cost may depend on factors such as your dosage, whether you have health insurance, and your treatment plan.

The price you pay for Vyvgart infusions can vary. It may depend on your treatment plan, your insurance coverage (if you have it), and where you receive Vyvgart intravenous (IV) infusions (injections into your vein given over time).

To find out how much you’ll pay for Vyvgart, talk with your doctor, or insurance provider.

Vyvgart is a biologic drug, which means it’s made from parts of living organisms. It doesn’t come in a biosimilar form. Biosimilars are like generic drugs. But unlike generics, which are made for nonbiologic drugs, biosimilars are made for biologics.

Why is there such a cost difference between biologic drugs and biosimilar drugs?

Biologic drugs can be expensive because of the research and testing needed to ensure their safety and effectiveness. The manufacturer of a biologic drug can sell it exclusively for up to 12 years. When the biologic drug’s patent expires, other drugmakers can create biosimilar versions. This competition in the market may lead to lower costs for biosimilars. And because biosimilars are very similar to biologic drugs, they don’t need to be studied again. This can also lead to lower costs for biosimilars.

Below are answers to some frequently asked questions about Vyvgart and cost.

Does Medicare cover Vyvgart?

It’s possible. There are several types of Medicare plans. Since Vyvgart is given as an IV infusion by a healthcare professional, your Medicare Part B plan may cover some or all of your cost.

Talk with your doctor or Medicare plan provider to learn whether Vyvgart is covered and what you can expect to pay.

What is Vyvgart’s annual cost?

Vyvgart’s annual cost depends on whether you have insurance or are paying out of pocket. (In general, Vyvgart’s cost is higher if you don’t have insurance coverage.)

Other factors that can affect the drug’s annual cost include:

  • your dosage and treatment plan
  • whether you qualify for any savings programs
  • your price to receive Vyvgart infusions at a clinic, hospital, or doctor’s office
  • any prior authorization requirements for your plan (if you have insurance coverage); see below for more information

To learn more about Vyvgart’s annual cost based on your individual situation, talk with your doctor or insurance provider (if applicable).

If you have insurance, you may need to get prior authorization before your insurance provider will cover Vyvgart. This means your insurer and your doctor will discuss Vyvgart in regard to your treatment. Then the insurance company will determine whether the drug is covered. If Vyvgart requires prior authorization and you don’t receive it before you start treatment, you could pay the full cost of the drug.

Be sure to ask your insurance company whether Vyvgart requires prior authorization.
