Twenty-Year-Old Drug "Best Yet" for Multiple Sclerosis, University of Cambridge Study

It's been a long time coming. An antibody approved 20 years ago to treat leukaemia has proved in two large clinical trials to be the best therapy yet for multiple sclerosis. Certain immune cells cause MS by attacking nerve cells. The drug works by temporarily destroying those immune cells. When they grow back, they no longer attack other cells. "It's like rebooting a computer," says Alasdair Coles from the University of Cambridge, who led one of the trials.
