Clinical Trial Summary

This clinical trial aims to demonstrate that metformin can prevent clinical disability in patients with progressive MS by stopping or slowing down neurodegeneration by enhancing endogenous remyelination. Patients will continue their DMT treatment: metformin or placebo will be used as add-on study treatment.


Clinical Trial Description

Multiple Sclerosis (MS) is a chronic neuroinflammatory and neurodegenerative disease leading to focal and diffuse damage of myelin sheath and axons in the central nervous system (CNS). Pathophysiologically, the adaptive and innate immune system are involved in the inflammatory process, while mitochondrial dysfunction, oxidative stress and failure of remyelination are important mechanisms leading to chronic neurodegeneration. Despite currently available disease modifying treatments (DMTs) that target the immune system, patients continue to accumulate disability. Unfortunately, no neuroprotective or remyelinating agents are available to treat progressive MS. Hence, drugs to tackle disease progression in MS represent a major unmet need. In this respect, metformin is a very interesting drug to investigate in MS patients as a neuroprotective and remyelinating therapy. Several preclinical studies in animal models of MS have shown that metformin has both anti-inflammatory, neuroprotective and remyelinating properties. A clinical study with metformin in a limited sample of MS patients did not demonstrate significant adverse events. The aim of this clinical trial is to provide evidence for the neuroprotective and remyelinating effects of metformin (I) in MS patients (P) via measurement of clinical and MRI outcome measures (O), via a multicentre randomized placebo-controlled (C) clinical trial. ;
