Amgen SupportPlus Co-Pay Program Patient Guide: How to Get Kanjinti (trastuzumab-anns) at Low or No Cost

Kanjinti (trastuzumab-anns) is a biosimilar to Herceptin used to treat certain types of breast cancer and gastric cancer. This guide explains the Amgen SupportPlus Co-Pay Program, which helps eligible patients with private or commercial insurance reduce out-of-pocket costs for Kanjinti to as little as $0 per dose. For uninsured or government-insured patients, Amgen refers to independent nonprofits.[1][2][4]

About Kanjinti and Why Access Matters

Kanjinti (trastuzumab-anns) is a prescription medicine approved for HER2-positive metastatic breast cancer, HER2-positive early breast cancer, and HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma, typically in combination with other cancer treatments. As a biosimilar to trastuzumab (Herceptin), it offers the same efficacy at potentially lower cost. Treatment involves intravenous infusions, often every 1-3 weeks, making affordability crucial for adherence.[1][2][6]

Cancer treatment costs can exceed thousands per dose without help. The Amgen SupportPlus Co-Pay Program targets out-of-pocket expenses like deductibles, co-insurance, and co-pays for commercially insured patients. Uninsured or government-insured (e.g., Medicare, Medicaid) patients don't qualify for the co-pay program but can get nonprofit referrals via Amgen SupportPlus.[1][2][3][4]

Who Qualifies for the Program?

Eligibility focuses on insurance type, not income:

  • Private or commercial insurance: Obtained through employer or bought directly (e.g., marketplace plans). No government insurance.[1][2][4]
  • U.S. resident with a valid prescription for Kanjinti.
  • Not eligible: Medicare, Medicaid, VA, Tricare, or other federal/state programs. These patients are directed to nonprofits.[1][2]

No income eligibility requirement—the program is open to all qualifying insured patients, regardless of finances.[3][4]

Income Eligibility Breakdown

The co-pay program has no income limits. However, for context on nonprofits (for uninsured/government-insured), many use Federal Poverty Level (FPL) thresholds like 400-500% FPL. Amgen provides referrals but doesn't administer these.[1][2]

Household SizeExample 400% FPL (2026 est.)Notes
Individual~$60,000Co-pay: No limit. Nonprofits vary.
Couple~$80,000Call 866-264-2778 for specific foundations.
Family of 3~$100,000Amgen refers only; nonprofits decide.
Family of 4~$120,000Check PAN Foundation, HealthWell, etc.

*Estimates based on standard FPL adjustments; actual nonprofit criteria differ. Co-pay program ignores income.[1][2]

Insurance Requirements

  • Eligible: Commercial/private insurance only. Program covers co-pays, deductibles, co-insurance up to annual maximums (terms at AmgenSupportPlus.com/copay).[3][4]
  • Ineligible: Government insurance (Medicare Part D, Medicaid). These patients cannot use co-pay cards and should call for nonprofit info.[1][2][7]

Alternatives if Denied or Ineligible
