On this episode of When Life Gives You Parkinson’s, despite some setbacks, there is still an appetite to trial a treatment for Parkinson’s that many believe is the antidote. GDNF, or glial cell line-derived neurotrophic factor, is naturally occurring and vital for normal functioning of the brain. But when GDNF is delivered directly to the brain, for some people, it is as if they’ve never had Parkinson’s.

The Phase II GDNF trial at the University of Bristol seemingly was made possible through the sheer will and force of the late Parkinson’s advocate Tom Isaacs and his Cure Parkinson’s Trust. The broadcast of Tom’s BBC Radio 4 documentary, Chasing a Cure, about the treatment was heard by Vicky Dillon. She vowed if a trial ever came around again, she’d sign up. And she did.

“We were the guinea pigs basically to see if we would tolerate the surgery and the insertion of all this plumbing in our brains. Tweet This

“They cut me from my hairline to like the middle part of my head and then put in all four catheters that went deep into my brain,” she said. “And then you had another bit of plumbing that runs down the side of your head to a port behind your left ear, which is where the infusions were given. So, there was quite a lot of stuff in there.”

Vicky was given GDNF for the better part of two years. Her symptoms improved almost immediately.

“By the time I took the second infusion, I noticeably felt different. I remember waking up a couple of days afterwards and there was no Parkinson symptoms for about an hour or so. I thought, ‘Oh my God!’ And gradually everything started getting better.”

Vicky’s symptoms improved 63 per cent, and on PET scans, all the participants showed potential for reawakening and restoring damaged brain cells, but the trial did not meet its primary endpoint.

“That’s ridiculous,” says Jayne Calder.

Her husband Darren was also in the trial and it improved his symptoms more than 50 per cent.

“Without any doubt whatsoever, in 100 per cent of those participants’ minds, we have got the cure for Parkinson’s.”

Vicky and Jayne are leading the charge to raise awareness and money for another trial. They have been very vocal. They’ve even recorded a song called Shine by the G.D.N.F.ers. Each download includes a donation to another GDNF trial.

They have also caught the attention of Parkinson’s UK. The organization’s chief executive Steve Ford is ready to throw massive amounts of money towards the project if everything on the application looks right.

“We spend around eight and a half million pounds annually. That’s $11 or 12 million a year on research. We haven’t seen the application yet, but we envisage it’s going to be in the order of an annual spend on research. So, that’s not significantly more than we’ve ever spent before.”

Recruiting for the next GDNF trial is expected to begin by the end of 2020 or early 2021.
