I went to the Biogen Idec website and clicked on management names. Then I found the contact us phone number and called asking for a name from the management list. I chose Susan Alexander (but she's out on vacation) so somebody from legal counsel is going to be calling me back.

Don't let them redirect you to patient support at Tysabri if you call them, get someone from corporate to talk to directly. I also left a voicemail for someone at the FDA to call me back.
