Abstract

Prolonged treatment with anti-CD20 antibodies can lead to hypogammaglobulinemia and increased infection risk in multiple sclerosis (MS). We investigated switch from anti-CD20 to cladribine as a strategy to prevent immunoglobulin reduction while preserving efficacy. We prospectively analysed serum IgG, IgM, neurofilament light (NfL) and glial fibrillary acidic protein (GFAP) in 44 patients, 14 who were switched from anti-CD20 to cladribine and 30 continuing anti-CD20. Over 1 year, serum IgG, IgM, NfL and GFAP remained stable after switch and similar to patients continuing anti-CD20. More than 90 % of patients remained free of disease activity. Cladribine should be further explored as de-escalating agent from anti-CD20 in MS.
