Double immune reconstitution therapy: Cladribine after alemtuzumab in the treatment of multiple sclerosis

Background and purpose: Alemtuzumab, a monoclonal anti-CD52 antibody, and cladribine, a purine nucleoside analogue, are used for the treatment of highly active relapsing-remitting multiple sclerosis (MS). Both are administered as two short yearly courses but possess the ability to induce long-term remission, labeling them as immune reconstitution therapies. Although disease activity after alemtuzumab administration is rare, there are a small number of people with MS who will experience disease activity despite repeated alemtuzumab treatment. Methods: We report on six patients with MS who experienced disease activity after alemtuzumab and were subsequently treated with cladribine and followed up for up to 2 years. Results: None of the patients experienced relapses during the follow-up period and in all patients Expanded Disability Status Scale values remained unchanged. All patients had lymphopenia at one time point. In patients 1 and 2, at the nadir, the lymphopenia was grade 1, in patient 3 it was grade 2 and in patients 5 and 6 it was grade 3. No infections or malignancies were recorded during the follow-up. Conclusion: This report provides a framework for treating people with MS with sequential immune reconstitution therapies.
