# Getting Plegridy at No Cost or Reduced Cost Through Biogen Support Services

Who Qualifies for Biogen Support Services?

If you need Plegridy (peginterferon beta-1a) and cannot afford it, you may be able to get it free or at a significantly reduced cost through the Biogen Support Services patient assistance program. For a single-person household, your annual income must generally be at or below $60,240 to qualify. In terms of insurance, this program is designed for patients who are uninsured, underinsured, or have commercial insurance that does not cover Plegridy. Medicare patients may also qualify under a separate Biogen Free Drug Program if they meet specific financial and clinical criteria. Biogen reviews each application individually, so even if your situation is complicated, it is worth applying.

About Plegridy (peginterferon beta-1a)

Plegridy is an FDA-approved prescription medication used to treat relapsing forms of multiple sclerosis (MS). This includes clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease. It belongs to a class of drugs called interferon beta-1a immunomodulators and is administered by injection. Without insurance coverage or financial assistance, Plegridy can cost thousands of dollars per month, placing it out of reach for many patients. Because there are currently no FDA-approved biosimilar versions of Plegridy available, patients do not have a lower-cost generic option, making manufacturer assistance programs like Biogen Support Services especially important.

Income Eligibility: Full Breakdown

Biogen uses household size and annual income to determine whether you qualify. The income limits below are based on 400% of the 2025 Federal Poverty Level (FPL):

| Household Size | Maximum Annual Income |

|---|---|

| 1 person | $60,240 |

| 2 persons | $81,760 |

| 3 persons | $103,280 |

| 4 persons | $124,800 |

To verify your income, Biogen typically asks for your most recent federal tax return, your last three months of pay stubs, or a W-2 form. If you are self-employed or have irregular income, you may be asked for alternative documentation.

If your income is above these limits, you are not automatically disqualified. Biogen states that it considers individual financial circumstances when reviewing applications. Out-of-pocket medical expenses, large household costs, or other financial hardships may be taken into account. It is still worth submitting an application and speaking with a Biogen Support Services representative at (800) 456-2255 to discuss your specific situation.

1. Gather your documents. Before you start, collect the following: proof of income (prior year tax return, W-2, or three months of pay stubs), a completed Enrollment Form, a prescription signed by your prescribing provider, your signed patient authorization, and your HIPAA authorization form.

2. Choose your application method. You have several options:

- Apply online by visiting https://www.plegridy.com/en_us/home/support/financial-assistance.html

- Call Biogen Support Services at (800) 456-2255 to apply by phone or get help with the process

- Fax your completed application and documents to (800) 843-6274

3. Complete the Enrollment Form. This form requires information about you, your household size, your income, your insurance status, and your prescribing provider. Your provider will need to sign the prescription section.

What to Expect: Timeline and Delivery

After you submit a complete application, Biogen Support Services typically makes a decision within 1 to 2 business days. Once you are approved, Plegridy is shipped directly to your home — you do not need to pick it up at a pharmacy or your doctor's office. Make sure someone is available to receive the shipment, as temperature-sensitive medications may require a signature.

Your enrollment in the program is not permanent. Annual reauthorization is required, meaning you will need to reapply each year to continue receiving assistance. Biogen will typically contact you before your enrollment expires. Keep your income documents updated so the renewal process goes smoothly.

Alternatives If You Don't Qualify

If you do not meet the eligibility criteria for the Biogen Support Services program, here are other options to explore:

1. Biosimilars: There are currently no FDA-approved biosimilar versions of Plegridy available in the United States, so this is not an option at this time.

2. Manufacturer savings card: If you have commercial insurance, Biogen offers a Plegridy Co-Pay Program that may reduce your out-of-pocket costs. You can learn more and enroll at https://www.plegridy.com/en_us/home/support/copay-program.html. This program is not available to Medicare or Medicaid patients.

3. State Pharmaceutical Assistance Programs (SPAPs): Many states run their own programs to help residents afford prescription drugs. Eligibility and benefits vary by state. Contact your state's health department or aging services office to ask about available programs.

4. NeedyMeds.org: This free, nonprofit database at www.needymeds.org allows you to search for patient assistance programs, drug discount cards, and other resources by medication name or condition.
