About GAMIFANT and its cost

What is this medication? Gamifant is a prescription medicine used to treat a rare and life-threatening immune system disorder called primary hemophagocytic lymphohistiocytosis, or HLH. It is specifically approved for use in both adults and pediatric patients, including newborn babies, who have primary HLH that has returned, has not responded to standard treatments, or has progressed during conventional therapy. This medication is also an option for patients who are unable to tolerate traditional HLH treatments due to side effects or other medical reasons.

The medication works as a monoclonal antibody designed to target and bind to interferon gamma, a protein that is produced in excessive amounts during an HLH flare. By neutralizing this protein, the drug helps to dampen the hyper-inflammatory response of the immune system and manage the severe symptoms associated with the condition. It is administered by a healthcare professional through an intravenous infusion, often serving as a critical step to help stabilize a patient before they can undergo a stem cell transplant.

GAMIFANT is made by Sobi. Like most brand-name drugs, it's priced at a high list price — but patients rarely pay that list price. The options above are the real paths most people use to get it affordably.

Common questions

What's the cheapest way to afford GAMIFANT?

It depends on your insurance. On Medicare, apply for the manufacturer's Patient Assistance Program (PAP) — it gives the drug free if you meet income requirements. With private insurance, the manufacturer copay card usually drops your copay to $0-$25. Uninsured patients should compare the PAP with Cost Plus Drugs cash price.

Can I use a copay card with Medicare for GAMIFANT?

No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But Sobi has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.

Does my Medicare Part D plan cover GAMIFANT?

Part D coverage varies by plan. We query the CMS Prescription Drug Plan file to show you what percentage of plans cover it and at what tier. For your exact copay, pick "Medicare" above and check your plan's Summary of Benefits, or log in to Medicare.gov.

How long does a Patient Assistance Program take?

Most PAPs take 2-6 weeks from application to first fill. Ask the manufacturer about a "bridge supply" — many will ship 30 days free while your application is being reviewed so you don't go without the drug.

What if I have a high-deductible plan?

For generics, Cost Plus Drugs cash price is often cheaper than your deductible-phase copay. For brand names, the manufacturer copay card almost always wins. A GoodRx coupon can be a last resort for uncovered drugs, but it doesn't count toward your deductible.

Are there charity grants for Systemic Juvenile Idiopathic Arthritis?

Charities like HealthWell Foundation, PAN Foundation, Good Days, and the National Organization for Rare Disorders provide copay help for specific conditions. Funds often run out mid-year — apply early. We list the specific grants for your condition in the options above.
