Title: A Multi-arm Phase IIB Randomised, Double Blind Placebo-controlled Clinical Trial Comparing the Efficacy of Three Neuroprotective Drugs in Secondary Progressive Multiple Sclerosis.
Brief Summary: Multiple sclerosis (MS) is a disabling and progressive neurological disease that affects approximately 100,000 people in the UK. Many patients with MS experience two phases of disease; early MS (also called relapsing remitting MS, RRMS) and late MS (also called secondary progressive MS (SPMS). Early MS is due to inflammation of the nerves and the insulation (called myelin) that surrounds the nerves. Early MS is often characterised by periods of "attacks" interspersed with periods of "remission" with no or low disease symptoms. Late or progressive MS, which affects the majority of patients and typically emerges after 10-15 years of disease, results from actual nerve death (also called neurodegeneration). The progressive stage of disease results not in individual attacks but slow, cumulative and irreversible disability affecting walking, balance, vision, cognition, pain control, bladder and bowel function. Critically, and unlike early disease, there is no proven treatment for the late stage of MS. This is therefore an urgent and major unmet health need. MS-SMART directly addresses this need and will evaluate in this clinical trial three drugs (fluoxetine, riluzole or amiloride), all of which have shown some promise in MS, and in particular in SPMS. The trial is randomised and blinded. Randomisation means patients can get any one of the three active drugs or the inactive placebo/dummy; blinded means that neither patients nor the doctors will know which drug or placebo patients are receiving. Randomisation and blinding are standard approaches in clinical trials to ensure unbiased testing of drugs. All patients in MS-SMART will have periodic MRI (magnetic resonance imaging) brain scans and after 96 weeks these will be analysed. We will then compare the scans of each drug to the placebo or dummy to see if any of the drugs slow the rate of brain shrinkage that normally occurs in SPMS. This measured change in brain size is the primary (major) outcome of MS-SMART.
