With all the excitement over vaccines and GDNF, don't over look the Exenatide PD trial, which is being carried out at the National Hospital for Neurology and Neurosurgery (part of the University College Hospitals Trust) in London. This diabetes drug showed promising results in a recent open trial and following on from this a level 2 double blind trial is now recruiting.
You can read more about it on the project website here:
You don't have to live in London to take part, if you live within a couple of hours from London, the project will pay the costs for you (and your partner/carer) to travel to London and, on the six occasions when you need to be seen unmedicated in the morning, they will put you up in a great little "boutique" hotel (which is owned by University College Hospitals).
Its an already approved drug so the side effects are well established (a common one is weight loss, which for many of us might not be a bad thing!). There's no surgery involved, though it is quite an intensive programme.
So, if you meet the criteria, why not volunteer? How do I know all this? Because I'm volunteer no: 9 and happy to answer any questions.
