About This Medication

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