A ground-breaking new medical trial has begun in the UK aimed at slowing the progress of multiple sclerosis. The Octopus trial is looking into whether existing drugs can be repurposed to help slow the progression of the condition. Alykhan, who was diagnosed with MS when he was still at school, is taking part in the study. He joins us in conversation with Professor Jeremy Chataway, from the National Hospital for Neurology and Neurosurgery in London, who is leading the trial.
