My mom inquired about this study. The study team at University of Pittsburgh received so much interest in the first few weeks after this was announced that they decided to do a group meeting as a first step instead of one-on-one meetings.

My parents attended this meeting last week, where my mom was one of about 15 Parkinson's patients present. They learned that participation in this study will require an eight-hour surgery under general anesthesia. Cancer (current or previous) is apparently a disqualifying criteria.
