Since John Kendrick was diagnosed with Multiple Sclerosis at 53 years old, his symptoms have become progressively worse and he is now in a wheelchair.

More than 20 years since his diagnosis, he has joined a clinical trial at Torbay and South Devon NHS Foundation Trust in the hope it will slow down or halt the loss of arm and hand function in people with advanced MS, external.

The study, which began in the UK in 2021, is being run at 22 sites and involves 205 people with advanced MS who are randomly assigned to take the drug cladribine or a placebo over 24 months.

“I’m worried about losing my legs and arms and being able to do things. So if it can stall it, I’d be very grateful,” he said.
