When I was "misdiagnosed" with SPMS and taking Avonex for over 2 years, my research led me to believe they (pharma and neuros) really didn't know if it would do any good.

I quit taking it saving me ruining my weekends with the flu symptoms side effects, not to mention having an intramuscular shot on Friday nights. Besides, they were charging my insurance company $3,500 a month for the med. A med nobody knew or knows would or is going to work. You tell me any one has patients in mind for any cure anytime soon?
