Ocrevus, also known by its generic name ocrelizumab, is a disease modifying treatment used for specific forms of multiple sclerosis. It is a CD20 directed monoclonal antibody that works by reducing certain B cells involved in immune system activity. In the United States, current approval includes relapsing forms of MS and primary progressive MS in adults, as well as relapsing remitting MS in pediatric patients aged 10 years and older who weigh at least 25 kilograms.
Ocrevus may help reduce disease activity in people with eligible forms of MS. Clinical studies have shown reductions in relapses, MRI measures of disease activity, and certain measures of disability progression in appropriate patient populations. For primary progressive MS, treatment has demonstrated an ability to slow some measures of disability progression compared with placebo.
Important points about its potential benefits include:
Treatment schedules and administration depend on the formulation and prescribing instructions. Intravenous Ocrevus begins with two 300 mg infusions separated by two weeks, followed by 600 mg infusions every six months.
Before treatment begins, healthcare professionals generally assess factors that could affect safety. The FDA prescribing information recommends hepatitis B screening, quantitative immunoglobulin testing, liver function testing, and review of vaccinations before starting treatment. Patients should also be assessed for active infection before each infusion.
Key considerations include:
The decision to use Ocrevus depends on the type of MS, medical history, infection status, vaccination history, laboratory results, and other individual factors. Patients should discuss potential benefits and risks with a qualified healthcare professional before starting, changing, or stopping treatment.
