This clinical trial focuses on studying the effects of stopping certain treatments in patients with a type of multiple sclerosis known as Secondary Progressive Multiple Sclerosis (SPMS). SPMS is a stage of multiple sclerosis where the disease gradually worsens over time. The study involves patients who are 50 years or older and have not shown recent signs of active disease, such as new symptoms or changes seen on an MRI scan, for at least three years. The treatments being studied include medications like Glatiramer Acetate, Cyclophosphamide, Interferon Beta-1A, Interferon Beta-1B, Mycophenolate Mofetil, Ocrelizumab, Rituximab, Teriflunomide, Dimethyl Fumarate, Azathioprine, and Methotrexate.
The purpose of the study is to see if stopping these treatments is not worse than continuing them in terms of how the disease progresses over two years. Participants will be divided into two groups: one group will stop their current treatment, and the other will continue. The study will monitor changes in disability, which refers to difficulties in physical activities, over the two-year period. This will help determine if stopping the treatment affects the progression of the disease.
Throughout the study, participants will have regular check-ups to assess their condition. These check-ups will include tests to measure physical abilities and brain scans to look for any changes. The study will also track any relapses, which are periods when symptoms suddenly get worse, and overall quality of life. The goal is to understand if stopping treatment is a safe option for patients with inactive SPMS who are older than 50 years.
