Ocrelizumab: A Breakthrough Treatment for Multiple Sclerosis, Protected by a Strong Patent Portfolio

Multiple sclerosis (MS) is a chronic and debilitating autoimmune disease that affects millions of people worldwide. The disease is characterized by the destruction of the protective covering of nerve fibers in the central nervous system, leading to a wide range of symptoms including vision loss, numbness, and difficulty with balance and coordination.

In recent years, ocrelizumab has emerged as a promising treatment for MS, offering a new hope for patients suffering from this debilitating disease. But what patents protect ocrelizumab, and how does it work?

What is Ocrelizumab?

Ocrelizumab is a humanized monoclonal antibody that targets CD20, a protein found on the surface of B cells. B cells are a type of immune cell that plays a key role in the development of MS. By targeting CD20, ocrelizumab depletes B cells from the bloodstream, reducing the production of antibodies that can exacerbate the disease.
