Who Qualifies for the Eisai Patient Assistance Program?
If you cannot afford Leqembi (lecanemab), you may be able to get it at no cost through the Eisai Patient Assistance Program. This program is designed to help patients who are uninsured, underinsured, or who have been denied coverage by their commercial insurance plan. To give you a quick benchmark: if you are a single-person household earning up to $60,240 per year, you may meet the income requirements. Households with more members have higher income limits. Medicare patients are not automatically excluded — some may qualify depending on their income level and medical situation. The program requires that your doctor confirm you have a valid diagnosis and a current prescription for Leqembi before assistance can be approved.

About Leqembi (Lecanemab)
Leqembi (lecanemab) is a prescription medication made by Eisai and Biogen. It is approved by the U.S. Food and Drug Administration (FDA) to treat adults with Alzheimer's disease at the mild cognitive impairment or mild dementia stage. Leqembi belongs to a class of drugs called amyloid beta-directed antibodies. It is given by intravenous (IV) infusion, typically at a medical facility. Without insurance or assistance, Leqembi carries a very high annual list price — estimates have placed it above $26,000 per year — putting it out of reach for many patients and families. There are currently no FDA-approved biosimilar or generic versions of this drug available.

Income Eligibility: Full Breakdown
The Eisai Patient Assistance Program uses household income limits based on a percentage of the Federal Poverty Level (FPL). The table below shows the maximum annual income allowed for each household size:
| Household Size | Maximum Annual Income |
|---|---|
| 1 person | $60,240 |
| 2 persons | $81,760 |
| 3 persons | $103,280 |
| 4 persons | $124,800 |
If your household has more than four people, the income limit generally continues to increase with each additional member. If your income falls slightly above these limits, you may still want to apply — some sources indicate that eligibility could extend to higher income levels depending on your documented medical expenses or other financial hardship factors.
Income is typically verified using your most recent federal tax return, a W-2 form, or three months of recent pay stubs. If your income has changed significantly since your last tax filing — for example, due to job loss or retirement — you may be able to submit pay stubs or a letter of explanation instead. Programs generally look at your total household income, meaning the combined income of everyone living in your home, not just the patient's income alone.

- Proof of household income (most recent tax return, W-2, or three months of pay stubs)
- A valid, current prescription for Leqembi from your doctor
- Your completed application form (available on the website)
3. Complete the application form. Both you (the patient) and your prescribing doctor must sign the application. Make sure all fields are filled out completely to avoid processing delays.

What to Expect: Timeline and Delivery
After you submit a complete application, processing typically takes 7 to 10 business days. Once your application is approved, the program will notify your prescribing doctor or their office. Leqembi is shipped directly to your prescriber's office or infusion facility — not to your home — because it is an IV medication that requires administration by a healthcare provider. You do not need to arrange pickup; your care team will coordinate the delivery with the program.
Assistance through this program is not permanent. You will need to reapply once per year to continue receiving Leqembi at no cost. Your prescriber will also need to reconfirm your diagnosis and medical need at that time. Keep track of your renewal date so there is no gap in your medication supply.

Common Questions
Yes. A caregiver, family member, or legal representative can help complete and submit the application on your behalf. Your prescribing doctor's signature is still required, and the patient information on the form must match your medical records.
Approval through the Eisai Patient Assistance Program lasts for one year. You will need to reapply annually and have your doctor reconfirm your diagnosis and prescription. It is a good idea to start the renewal process a few weeks before your approval expires to avoid any gap in treatment.
No. Because Leqembi is given as an IV infusion, it is shipped directly to your prescriber's office or infusion center — not to your home. Your care team will coordinate delivery and let you know when your medication is available.
If your financial situation has changed since your last tax return was filed, you may be able to submit recent pay stubs, a termination letter, or other documentation to reflect your current income. Contact the program at (833) 453-7362 to ask how to document a change in income.
No. Applying to the Eisai Patient Assistance Program is free. You should never be charged a fee to apply to a manufacturer patient assistance program. If approved, eligible patients typically receive Leqembi at no charge for the duration of their approved period.
