Who Qualifies for Pfizer Oncology Together?
If you have been prescribed Bosulif (bosutinib) for chronic myeloid leukemia and are struggling with the cost, you may be able to get it at no charge through the Pfizer Oncology Together Patient Assistance Program. This program is designed specifically for patients who cannot afford their medication. For a single-person household, the maximum annual income to qualify is $75,300. In terms of insurance, you may qualify if you are uninsured, underinsured, have commercial insurance that does not fully cover Bosulif, or have Medicare Part D and meet the income requirements. Patients with full Medicaid coverage are generally not eligible. If you are not sure where you stand, the sections below walk through each situation in plain language.

About Bosulif (Bosutinib)
Bosulif is a prescription medication manufactured by Pfizer. It is FDA-approved to treat adults with Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML), including newly diagnosed cases and cases that have not responded well to other treatments. Bosulif belongs to a class of drugs called tyrosine kinase inhibitors (TKIs), which work by targeting specific proteins involved in cancer cell growth. Without insurance or financial assistance, the cost of Bosulif can run into tens of thousands of dollars per year, placing it out of reach for many patients. Because no FDA-approved biosimilar alternatives currently exist for Bosulif, the brand-name drug is the only available option, making patient assistance programs especially important.

Income Eligibility: Full Breakdown
Pfizer Oncology Together uses an income threshold of approximately 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 |
Income is typically verified using your most recent federal tax return, W-2 form, or three months of recent pay stubs. Pfizer will generally look at your prior year income when reviewing your application.
If your income is above these limits, you may still have options. See the "Alternatives If You Don't Qualify" section below for savings cards and other resources that may help.
Household size matters and can work in your favor. If you support dependents, your eligible income threshold increases with each additional person in your household. When completing your application, make sure to accurately report everyone in your household, as this can affect whether you qualify. If your situation has changed significantly since your last tax return — such as a job loss or reduction in hours — contact the program directly at (877) 744-5675 to ask whether alternative income documentation may be accepted.

What to Expect: Timeline and Delivery
Once your application is submitted with all required documents, a decision is typically made within 2 to 3 business days. You or your physician's office will be notified of the outcome. If approved, Bosulif will be shipped directly to your home address — you do not need to pick it up at a pharmacy. There is nothing additional required at the time of delivery. To continue receiving medication through the program, you will need to reauthorize your enrollment annually. Pfizer will typically reach out as your renewal period approaches, but it is a good idea to track your enrollment date and begin gathering updated income documents ahead of time.

Alternatives If You Don't Qualify
If you do not meet the income or insurance requirements for the Patient Assistance Program, consider these options:
1. No FDA-approved biosimilars for Bosulif currently exist, so a lower-cost generic or biosimilar substitution is not available at this time.
2. Bosulif Copay Savings Card: If you have commercial (private) insurance, you may be eligible for the Pfizer Oncology Together Copay Savings Card, which can reduce your out-of-pocket costs at the pharmacy. Apply at https://www.pfizeroncologytogether.com/commercial-patient/bosulif-copay-savings-card.
3. State Pharmaceutical Assistance Programs (SPAPs): Many states offer their own programs to help residents afford prescription drugs, particularly for seniors and people with disabilities. Eligibility and benefits vary by state. Contact your state's department of health or aging to find out what may be available to you.
4. NeedyMeds.org: This free, independent database lists hundreds of patient assistance programs, copay assistance options, and disease-specific resources. Visit https://www.needymeds.org to search by drug name or condition at no cost.
