TRAK Assist Patient Guide: How to Get Vitrakvi (Larotrectinib) at Low or No Cost

About This Program

TRAK Assist is Bayer's patient support program designed to help eligible patients access Vitrakvi (larotrectinib), a prescription medication used to treat certain cancers with specific genetic mutations. The program recognizes that affording necessary medications can be challenging and offers multiple pathways to assistance based on your insurance status and financial situation.

What Is Vitrakvi?

Vitrakvi is a targeted cancer therapy prescribed for patients with tumors that have a neurotrophic receptor tyrosine kinase (NTRK) gene fusion without known acquired resistance mutations. It is available in two formulations: 100-mg capsules and 20-mg/mL oral solution. Your healthcare provider will determine if Vitrakvi is appropriate for your condition and will need to confirm you have an FDA-approved test showing the NTRK gene fusion.

Who Qualifies for TRAK Assist?

TRAK Assist serves three main patient populations:

Commercially Insured Patients: If you have active health insurance, you may qualify for co-pay assistance to reduce your out-of-pocket costs for Vitrakvi.

Patients with Coverage Gaps: The Bridge Program provides temporary medication assistance if you experience delays or lapses in your insurance coverage, helping ensure you don't miss doses during transitions.

Uninsured and Low-Income Patients: If you lack insurance or have limited income, you may qualify for the Bayer US Patient Assistance Foundation program, which can provide Vitrakvi at no cost. Eligibility is determined based on household income and financial need, with specific thresholds established by the program.

Income Eligibility

While specific income thresholds are not publicly listed, TRAK Assist and the Bayer US Patient Assistance Foundation use a sliding scale based on your household income and family size. The program typically considers:

CategoryConsideration
IndividualIncome-based eligibility determined by program
CoupleCombined household income evaluated
Family of 3+Household income relative to family size
DocumentationPhysical proof of income may be requested

To learn your specific eligibility, you'll need to contact the program directly or complete an application. The program uses electronic income verification when possible to streamline the process.

Insurance Requirements

If You Have Commercial Insurance: You are eligible for the co-pay assistance program. You'll need to provide proof of your current insurance (front and back of your pharmacy card).

If You Have Medicare or Medicaid: Contact TRAK Assist to discuss your specific situation, as coverage options may differ.

If You Are Uninsured: You may qualify for free medication through the Bayer US Patient Assistance Foundation program based on income eligibility.
