One of the possible therapies my neuro mentioned to me was rituxan. After reading about it I have to admit it scares me. After my experience with tysabri I am hesitant to try a drug that is also associated with PML's and infusion deaths.

I was also wondering about estirol. He did not mentioned it but I do know they are currently testing it.

I think I would like to hold out for tovaxin if it is likely it will be approved in the next year.
