Amgen SupportPlus Patient Guide: How to Get Vectibix (panitumumab) at Low or No Cost

Vectibix (panitumumab) is a prescription medicine used to treat certain types of metastatic colorectal cancer (mCRC) in adults, specifically when used with other treatments like FOLFOX chemotherapy for RAS wild-type mCRC or with LUMAKRAS (sotorasib) for KRAS G12C-mutated mCRC. Amgen SupportPlus is Amgen's comprehensive patient support program that offers personalized financial assistance, nurse support, and resources to help you access Vectibix regardless of your insurance status.[1][4][5]

About Vectibix and Why Assistance Matters

Vectibix is given as an intravenous (IV) infusion every two weeks by your healthcare provider. It's not for patients with RAS-mutant mCRC (unless combined with sotorasib in specific cases) or unknown RAS status. Common side effects include dermatologic toxicities (skin reactions in 90% of patients, severe in 15%), low magnesium levels, infusion reactions, and others—discuss risks with your doctor.[4]

Cancer treatment can be expensive, with high out-of-pocket costs for infusions, co-pays, or uninsured scenarios. Amgen SupportPlus bridges this gap by providing co-pay assistance, free medicine for qualifying uninsured patients, and help with insurance navigation. It's available to everyone, no matter your finances or coverage.[1][5]
