Hi thee, I don’t know where you are writing from, but I would think that every ‘certified’ ALS Center can point you in the right direction. I URGE you to find one, as we ALL benefit by as much participation in clin trials as possible. There are MANY out there, some simple with others quite complex. IF you have any difficulty finding one through your ALS center, try one of the larger and active centers: 1] Healey Center at Mass General; 2] Johns Hopkins in Baltimore; ] Emory Univ in Atlanta. Good luck! If you answer where you live, someone on this site can help you find something close.
