Ocrevus was approved by the FDA in March of 2017. It is the only medication approved for primary progressive multiple sclerosis although it can also be used for relapsing-remitting MS. It has a different method of dealing with the immune system.
Most MS drugs modify the T-cells of the immune system. Ocrevus is one of the only drugs that targets the myelin-attacking mature B cells.
Ocrevus changes the B cells of the immune system which is, so far, more successful.
Ocrevus slowed the progression of primary progressive MS, which is the most severe form of multiple sclerosis. It also reduces disease activity. It is always good to have things quiet down with MS.
Primary progressive MS affects about ten percent of people with multiple sclerosis. It’s the type of multiple sclerosis that I have. How it was sent into remission is described in my book at https://www.amazon.com/Multiple-Sclerosis-Mission-Remission-Healing-ebook/dp/B07D7JBZ5L/ref=mp_s_a_1_2?ie=UTF8&qid=1529367853&sr=8-2&pi=AC_SX236_SY340_FMwebp_QL65&keywords=multiple+sclerosis+Mission+remission
