What is Ocrevus (ocrelizumab) for?
Ocrevus (ocrelizumab) is a CD20-directed cytolytic antibody indicated for the treatment of people with relapsing or primary progressive forms of multiple sclerosis (MS)[1,4]. It is the first approved treatment for the primary progressive form of MS[2].
Relapsing MS (RMS) is characterized by episodes of worsening function (relapses) which are initially followed by recovery periods (remissions). In its primary progressive form (PPMS), MS is characterized by steadily worsening function from the onset of symptoms, often without early relapses or remissions[2].
How does Ocrevus (ocrelizumab) work?
MS is a chronic, inflammatory, autoimmune disease that affects the central nervous system, and in particular the communication between the brain and other parts of the body[2].
The patient’s own immune system is supposed to be the cause of the damage to neurons[3].
The precise mechanism by which ocrelizumab exerts its therapeutic effects in multiple sclerosis is unknown, but is presumed to bind to a type of antigen, named CD20, found on the surface of some antibodies (pre-B and mature B lymphocytes) and induce their death[2]. In this way, it is supposed to prevent these antibodies from damaging neurons.
