More Davunetide comments... On february of 2011 I became a part of the experimental drug, DAVUNATIDE. After 4 months i started to walk with a walker and i got my normal voice back. http://psp.healthunlocked.com/blogs/47085/My-journey-through-PSP CateT 18 Jul 2012Report I do think there is a real possibility. The trial is winding down now and I guess results will be published soon. My mum was on the trial but it was a blind placebo based one and we will only find out in a couple of months whether or not she had the actual medication. I do believe that she was relatively stable whilst on the trial but this could be due to anything - PSP is such a great unknown. http://psp.healthunlocked.com/blogs/374750/davunetide
