The TYSABRI TOUCH^® Prescribing Program

How we monitor your safety and manage your risks.

If you're considering TYSABRI for your relapsing MS, you should know that it may increase your risk of developing a brain infection called progressive multifocal leukoencephalopathy (PML). To help manage this risk, TYSABRI is only available through the TOUCH Prescribing Program.

TOUCH, which stands for TYSABRI Outreach: Unified Commitment to Health, was developed with the help of the Food and Drug Administration (FDA). It ensures that:

• Only prescribers and patients enrolled in TOUCH can prescribe and receive TYSABRI
• Only certain pharmacies and infusion sites authorized by TOUCH can dispense and infuse TYSABRI

With TOUCH, you have frequent interaction with doctors and nurses. Your treatment is closely monitored at each infusion visit (every 4 weeks) to help make sure TYSABRI continues to be right for you. In addition to these visits, plan to see your doctor 3 months after your first infusion, 6 months after your first infusion, and at least as often as every 6 months thereafter.

Signing up for TOUCH is the first step.

In order to begin receiving TYSABRI, you must first enroll in TOUCH. The process begins by making an appointment with your prescribing neurologist in order to fill out the TOUCH Patient/Prescriber Enrollment Form. At this appointment, the neurologist will explain the potential benefits and risks of TYSABRI and will give you time to ask any questions. You must then read the Patient Medication Guide (PDF) and sign the TOUCH Enrollment Form.

By signing this form, you acknowledge that you understand the potential risks associated with TYSABRI and agree to the requirements of the TOUCH Prescribing Program. This document also serves as your prescription.

Once you've signed the form, Biogen Idec will assign you a patient identification number, make sure all paperwork has been properly filled out, and ensure that you have insurance coverage. Then they'll help you find an infusion center and notify the center that you've been approved for an infusion.

TOUCH also assigns you your own specially trained Biogen Idec Case Manager to help:

• Get you started on therapy and answer questions you may have
• Find an authorized infusion site in your area
• Provide information about insurance coverage and possible sources of financial assistance, if needed
