Below is a link to the Georgetown study published July 11, 2016. The first study was a safety study so naturally the next step is the double blinded study which is what The Fox Foundation and partners are planning to start in 2017! I'm hoping the Georgetown folks will also do a double blind study as well. Also it seems likely that the UK based Cure Parkinsons Trust will study this on their side of the ocean so we should have ample study results around the world to determine if the Nilotinib direction will be useful to be a real game changer in treating PD!
