This clinical trial is focused on studying the effectiveness and safety of a treatment for Progressive Multiple Sclerosis (PMS), a type of multiple sclerosis where symptoms gradually worsen over time. The treatment being tested is called Ocrelizumab, which is administered as a solution for infusion. The study aims to understand how well this treatment works in managing the disease and ensuring patient safety.
Participants in the study will receive Ocrelizumab over a period of four years. During this time, researchers will monitor the patients to see if there is any progression of the disease and to check for any side effects. The study will also involve regular assessments to evaluate changes in cognitive function, mobility, and overall impact on daily life. These assessments will help determine the effectiveness of the treatment in slowing down or stopping the progression of the disease.
In addition to Ocrelizumab, other medications such as Diphenhydramine Hydrochloride, Paracetamol, and Methylprednisolone may be used as part of the study to manage symptoms or side effects. The study will also include a placebo group to compare the results. The goal is to gather comprehensive data on how Ocrelizumab affects patients with Progressive Multiple Sclerosis and to ensure that the treatment is both effective and safe for long-term use.
