About This Medication

# Eisai Assistance Program Patient Guide: How to Get Halaven (eribulin mesylate) at Low or No Cost Halaven (eribulin mesylate) is a prescription chemotherapy injection used to treat certain types of metastatic breast cancer and liposarcoma in adults when other treatments have not worked well enough. The **Eisai Assistance Program** helps **financially needy, uninsured, or underinsured patients** get Halaven at no cost if they meet eligibility rules, which include proving financial need through documents like tax returns and being a US resident[1][3][4]. ## About Halaven (eribulin mesylate) **Halaven** is an injectable medicine given by a healthcare professional, usually every 3 weeks, to slow or stop the growth of cancer cells in **metastatic breast cancer** (cancer that has spread) or **unresectable liposarcoma** (a rare soft tissue sarcoma). It works by blocking microtubules, structures cancer cells need to divide and grow. Common side effects include fatigue, nausea, hair loss, and low white blood cell counts—always discuss risks with your doctor. This program focuses on access for those who can't afford it, not medical advice[2][5][6]. ## Who Qualifies for the Eisai Assistance Program? This program is for **US residents** (including Puerto Rico) who are **uninsured or underinsured** and **financially needy**. 'Financially needy' means you can't afford your medicine based on income and expenses—there's **no fixed income limit** like a percentage of the Federal Poverty Level (FPL). Eisai reviews applications **case-by-case**, considering your full financial picture. You must not get the medicine through other free sources[1][3][4][6][7]. **Key eligibility points:** - US citizen or legal resident. - Uninsured (no coverage) or underinsured (coverage doesn't pay enough). - Provide proof of financial hardship. - Prescribed for an FDA-approved use by a licensed doctor. **Note:** This is **separate from the HALAVEN $0 Co-Pay Program**, which is for **commercially insured patients** (not Medicare/Medicaid) to cover copays up to $18,000/year. If you have commercial insurance, check that first[1][2][5][8]. ## Income Eligibility Breakdown No strict cutoffs exist; eligibility is determined individually based on income, expenses, assets, and household size. Submit documents showing your situation—Eisai decides if you're 'financially needy.' Here's a general guide based on similar programs (not official Eisai thresholds): | Household Size | Example Annual Income Range (for Guidance) | Notes | |---------------|--------------------------------------------|-------| | 1 (Individual) | Under $30,000–$50,000 | Depends on debts, medical costs[4] | | 2 (Couple) | Under $40,000–$65,000 | Case-by-case review[3] | | 3 | Under $50,000–$80,000 | Include all household income[1] | | 4+ | Under $60,000–$100,000+ | Higher for larger families; no max FPL stated | **Always apply—even if unsure.** Provide recent tax returns (e.g., 1040 form), pay stubs (last month), Social Security statements, or proof of unemployment/benefits. Eisai may ask for more[3][4]. ## Insurance Requirements - **Uninsured:** No insurance at all—fully eligible if financially needy. - **Underinsured:** Insurance exists but doesn't cover Halaven fully (e.g., high copays, denials). Attach insurance cards; program may cover the gap. - **Not eligible if:** Enrolled in government programs for the co-pay card (but PAP may still help case-by-case). Patients with coverage that fully pays typically don't qualify[2][4][6][7]. ## Step-by-Step Application Process 1. **Talk to your doctor:** They must complete part of the form, including prescription details (strength, dosage, quantity), their signature, DEA/NPI number, and preferred administration site. 2. **Download the form:** Get the **Eisai Patient Assistance Program Enrollment Form** from eisaipatientsupport.com or call (866) 613-4724. 3. **Fill it out completely:** - Patient info (name, address, DOB, phone). - Insurance details (attach cards if any). - Financial section: Year-to-date spending, income sources. - Sign in all patient sections. 4. **Gather documents:** - Financial proof: Tax returns, pay stubs (1 month), SS awards, bank statements. - Insurance cards (front/back). 5. **Submit by fax:** Fax **everything** to **1-855-246-5192**.
