Doctors in
Cambridge believe they are “on the brink of a new class of treatments” for multiple sclerosis (MS) after a trial in patients suggested nerve damage may be repaired.
The treatment involves combining the common diabetes drug, metformin, with clemastine, an antihistamine, to help repair myelin.
This is the protective membrane that wraps around nerve cells. It becomes damaged in MS and causes symptoms such as fatigue, pain, spasms and problems with walking.
Previous evidence from animal studies found metformin enhanced the effect of clemastine on myelin repair, but until now the two drugs have never been tested together in people.
Dr Nick Cunniffe, academic neurologist at the University of Cambridge, who led the latest CCMR-Two trial, said: “I am increasingly sure that remyelination is part of the solution to stopping progressive disability in MS.
“We still need to research the long-term benefits and side-effects before people with MS consider taking these drugs.
“But my instinct is that we are on the brink of a new class of treatments to stop MS progression, and within the next decade we could see the first licensed treatment that repairs myelin and improves the lives of people living with MS.”
