MS is a chronic autoimmune disease, in which your own immune system attacks the protective layer around your nerves by mistake. It does this using two different types of white blood cell, B cells and T cells.¹

MS can cause many different symptoms, such as fatigue, difficulty walking, muscle spasms and vision problems.²

Ocrevus is a medicine for adults who have either primary progressive MS (PPMS), like you, or relapsing remitting MS (RRMS).³

Ocrevus is classified as a highly effective disease modifying treatment (HE DMT). In primary progressive MS, research studies show that Ocrevus treatment significantly slows down the progression of your disease when compared to placebo.⁴ For example, it delays the deterioration of walking speed, which can help you keep walking.⁵

Patients on Ocrevus also show fewer signs of the disease being active, such as brain lesions.³

The active ingredient in Ocrevus is ‘ocrelizumab’, a type of protein called a ‘monoclonal antibody’. Antibodies work by attaching themselves to specific targets in your body.⁶

Ocrevus targets and removes specific B cells – a type of white blood cell that forms part of the immune system and plays a role in MS.⁶

Removing these cells reduces inflammation and attacks on the myelin sheath (the protective membrane around your nerves that keeps brain signals moving through the body). This can help to control the frequency and severity of symptoms and delay the worsening (progression) of your disease.³
