Who Qualifies for the Xtandi Support Solutions / Astellas Pharma Support Solutions?
If you cannot afford Xtandi (enzalutamide), you may be able to get it at no cost through the Xtandi Support Solutions / Astellas Pharma Support Solutions program. This program is run by Astellas, one of the manufacturers of Xtandi, and is designed to help patients who lack adequate prescription coverage or cannot afford their medication.
For a single-person household, the maximum annual income to qualify is $75,300. Larger households may qualify at higher income levels. To be eligible, you must be uninsured, underinsured, or enrolled in Medicare Part D and meet specific financial criteria where no other coverage option exists. Astellas reviews each application individually, so even if you are unsure whether you qualify, it is worth applying.

About Xtandi (Enzalutamide)
Xtandi (enzalutamide) is an androgen receptor inhibitor approved by the FDA to treat several forms of prostate cancer, including castration-resistant prostate cancer (CRPC), metastatic castration-sensitive prostate cancer (mHSPC), and non-metastatic castration-resistant prostate cancer (nmCRPC). It is co-developed and marketed by Pfizer and Astellas Pharma.
Xtandi is a specialty medication, meaning it is manufactured through a complex process and is not available as a generic or biosimilar. Without insurance or financial assistance, the out-of-pocket cost can reach tens of thousands of dollars per year, making it unaffordable for many patients. The Xtandi Support Solutions program exists specifically to help bridge that gap.

Income Eligibility: Full Breakdown
The program generally sets its income limit at 500% of the Federal Poverty Level (FPL). The table below shows the maximum annual income allowed based on household size:
| Household Size | Max Annual Income |
|---|---|
| 1 person | $75,300 |
| 2 persons | $102,200 |
| 3 persons | $129,100 |
| 4 persons | $156,000 |
If your household has more than four people, the income limit typically increases incrementally for each additional member. Contact the program directly at (855) 898-2634 to ask about your specific household size.
Income is usually verified using your most recent federal tax return (Form 1040), a W-2, 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 other documentation to reflect your current financial situation.
If your income is above the listed limits, do not assume you are automatically disqualified. Astellas evaluates applications on a case-by-case basis, taking medical necessity and financial hardship into account. You may still be considered if you have unusually high medical expenses or other significant financial burdens.

What to Expect: Timeline and Delivery
Once your application is submitted, the program typically completes its review within two business days. You or your doctor's office will be notified of the approval decision. If approved, Xtandi is shipped directly to your home — you do not need to pick it up at a pharmacy or your doctor's office. There is nothing you need to do at the time of delivery other than be available to receive the shipment.
Approval is not permanent. The program requires annual reauthorization, meaning you will need to reapply each year to continue receiving your medication. Your care team or a program representative will typically notify you when it is time to renew.
