Multiple sclerosis (MS) is a neurological condition which is a common cause of disability in young people. It is thought to be an autoimmune condition, where the body's immune system begins to attack itself. The cause of MS is unknown but is thought to be a mix of genetic and environmental factors. There are treatments available for early stages of MS, but the later stage known as Secondary Progressive MS (SPMS) has no current treatment.
Statins are a safe treatment traditionally used to reduce cholesterol levels. However, statins also have other effects which could reduce the progression of SPMS, such as effects on the immune system and circulation. A recent study (Chataway et al., 2014) showed that treatment with high-dose simvastatin, a type of statin, reduced the progression of SPMS but no effect on the immune system was seen. It is possible that simvastatin does not treat the immune system but improves how the blood and blood vessels in the brain work in this disease.
The purpose of the clinical trial is to test how Simvastatin (80mg/day) may slow down disease progression in people living with SPMS compared to placebo (dummy pill). Participants will receive either Simvastatin or placebo and will be asked to take 2 tablets daily, for up to 17 weeks.
