Rituximab for Multiple Sclerosis: Hiding in Plain Sight

ABSTRACT

In February 2023, following extensive discussions with stakeholders and data review, the Institute for Clinical and Economic Review issued final policy recommendations for treatment of relapsing multiple sclerosis (RMS)1 "All stakeholders have a responsibility and an important role to play in ensuring that all effective treatment options for patients with RMS, including off-label use of rituximab, are utilized in ways to help improve affordability and access and reduce health inequities." The report calls on payers to remove barriers to rituximab coverage, the American Academy of Neurology and the National MS Society to publicly endorse rituximab for RMS, and clinicians to advocate for coverage of rituximab and its biosimilars. In July 2023, the World Health Organization listed rituximab as an essential medicine for MS.2 Yet not much has changed. Food and Drug Administration (FDA)-approved MS disease-modifying therapies continue to generate enormous profits for pharma, and rituximab remains hidden in plain sight.
