Howdy Nancy, I am currently taking part in a patch study. It is "A MultiCentre, Randomized, Double-Blind, Placebo Controlled, Parallel Group, Dose-Ranging Study to Assess the Efficacy, Safety and Tolerability of Escalating Transdermal Doses of SPM 962 (Dopamine Agonist) in Subjects with Early Stage Parkinson's Disease." Wow that's a mouthful!!! I put on 4 small patches on my upper abdomen every morning and they stay on until the next day. I am thrilled with "my" results and will be sad to see this phase of the study come to an end (August 30th). My Neurologist, who is a Movement Disorder Specialist, and I were interviewed and filmed for a PD segment with regards to PD and new research. It aired on a local TV station last month. The Study Chair is Dr. Ira Shoulson in Rochester NY...I'm based in Calgary Alberta. My Dr tells me that she expects there will be a "phase 3" to this study in the not too distant future. Hope this helps. Please let me know if you need more info. Kelly in Calgary 40\39\36
