This clinical trial is focused on studying the effects of adding metformin to the treatment of patients with Progressive Multiple Sclerosis (PMS). Metformin is a medication commonly used to treat diabetes, and researchers are investigating whether it can help slow down the progression of PMS. The study will compare the effects of metformin with a placebo, which is a substance with no active medication, to see if metformin can improve walking speed and other health measures over a period of 96 weeks.
Participants in the study will receive either metformin or a placebo and will be monitored for changes in their condition. The main focus is to see if metformin can delay the progression of the disease, as measured by walking speed. Other aspects of health, such as cognitive function, hand function, and quality of life, will also be assessed. These assessments will be done using various tests and measures, including the Expanded Disability Status Scale (EDSS) and the Symbol Digit Modalities Test (SDMT).
The study will also use MRI scans to look at changes in brain volume and other brain characteristics over time. The trial is designed to be “triple-blind,” meaning that the participants, the healthcare providers, and the researchers do not know who is receiving the metformin or the placebo. This helps ensure that the results are unbiased and reliable. The study aims to provide valuable information on whether metformin can be an effective add-on treatment for people with PMS.
