Hello Terry~
I'm sorry to hear about your diagnosis. I am a Nurse/Clinical Research Coordinator with a Neurologist. I don't know very much about the investigational compunds that your MD is testing, but I do know that you can look up information on clinicaltrials.gov.
Also, when you meet with your Doc again to discuss your possible involvement in the trial it might be helpful to know what phase the trial is in, how many patients in his site have already enrolled and the most commonly reported side effects to date. Also, you can ask what Safety Reports have come back from the pharmaceutical company and what they have reported.
Good luck to you and I will keep you in my prayers.
