Secondary progressive MS

Brief summary

Clozapine and risperidone are medicines that are currently used to treat mental health disorders. These medicines have been shown to have anti-inflammatory effects in the brain and therefore may also be useful for treating multiple sclerosis (MS). At the dose used in patients with mental illnesses clozapine and risperidone can have a range of side effects, but research has shown that a lower dose may be suitable for treating MS.

The main purpose of this study is to assess the safety and acceptability of treatment with a low dose of clozapine or risperidone in patients with secondary progressive MS by comparing their use to people given a placebo (inactive medicine). The study will also look at whether these medicines can reduce the symptoms of MS, and how they might affect the immune system. This information will help determine if one or both of these medicines should be further developed as a treatment for MS.
