Tysabri Dosage Survey - January 2017

A team of neurologists from the NYU Langone Multiple Sclerosis Comprehensive Care Center in New York City is applying for funding to study dosing patterns of natalizumab (Tysabri).  They are interested to learn if extended dosing (infusions every 5 - 8 weeks) is as effective as the standard dosing interval (infusions every 4 weeks).  They have asked the iConquerMS™ community to assist with developing this application by answering a few survey questions.  The survey should take no more than 5 minutes to complete.

The information gathered will help them better understand the current knowledge and practices of people who have been or are currently on Tysabri.

1. Have you used Tysabri as a disease modifying therapy for your MS, either now or in the past? *This question is required.
Has your neurologist discussed the option to have the Tysabri infusion done on an extended dose schedule of every 5-8 weeks in place of the standard dose schedule of every 4 weeks?
Thank you for your time.  The remaining questions are only applicable to participants who are or have been on Tysabri.
