At the 2015 European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) meeting Barcelona on Friday, Dr Stephen Hauser (UCSF) presented the data for octrelizumab, an anti-CD20 monoclonal antibody, on behalf of the investigators in the OPERA trial. This study compared octrelizumab to a standard of care at the time the study started i.e. IFN β-1a (Rebif).
Roche previously announced that ocrelizumab is the first investigational medicine to show positive pivotal study results in both relapsing and primary progressive forms of multiple sclerosis (MS):
- Ocrelizumab showed superiority to interferon beta-1a (Rebif®) in two identical Phase III studies in people with relapsing multiple sclerosis (MS), the most common form of the disease.
- Ocrelizumab is the first investigational medicine to show efficacy in people with primary progressive MS in a large Phase III study.
In addition, Dr Montalban presented the latest data for octrelizumab in primary progressive MS versus placebo (there are no approved therapies for this segment) on behalf of the ORATORIO investigators.
Here on BSB we have extensively covered other anti-CD20 monoclonal antibodies such as rituximab, ofatumumab and obinutuzumab in oncology indications specifically associated with hematologic malignancies, so what’s special about this same target and the results in MS with a different chemical entity?
