About

The primary aim of this project is to determine whether there are differences in access to, efficacy and tolerability of Ocrelizumab in men and women of different racial and ethnic origins and socio-economic backgrounds with RRMS and PPMS in two large academic MS Centers with a high volume of patients on Ocrelizumab. The study is a retrospective analysis of multiple sclerosis patients cared for at Brigham and Women's Hospital and Boston Medical Center who were treated with Ocrelizumab during the 4 year study period.

Full description

This study will be a two-center retrospective/observational analysis with data collected from the Research Patient Data Registry (RPDR), Brigham Multiple Sclerosis Center Patient Database (Oracle), and Boston Medical Center MS Clinic Database (BMC-MS).

Using the Oracle database, BMC-MS database and electronic medical records (EPIC), the investigators will capture all MS patients who satisfy inclusion criteria. This study will collect age, sex, race, socio-economic status by residence zip code, disease duration, previous treatment, current treatment status, the reason for discontinuing or switching to another treatment, expanded disability status scale (EDSS), and functional systems scores (FSS) where available.

Additionally, the investigators will collect the date, dose, and interval between each ocrelizumab infusion, as well as any pertinent laboratory values and MRI scan results.
