Abstract | BACKGROUND: Progressive multiple sclerosis (PMS) is a debilitating condition characterized by progressively worsening symptoms. Monoclonal antibodies are novel therapies for MS, but their safety and efficacy in the progressive form have not been comprehensively studied. In this systematic review, we aimed to evaluate the available evidence regarding monoclonal antibody treatment for PMS. METHODS: After registration of the study protocol in PROSPERO, we systematically searched three major databases for clinical trials involving monoclonal antibodies administration for PMS treatment. All the retrieved results were imported into the EndNote reference manager. After removing the duplicates, two independent researchers did the study selection and data extraction. The risk of bias was assessed using the Joanna Briggs Institute (JBI) checklist. RESULTS: Of the 1846 studies in the preliminary search, 13 clinical trials investigating monoclonal antibodies ( Ocrelizumab, Natalizumab, Rituximab, and Alemtuzumab) in PMS patients were included. Ocrelizumab was significantly effective in reducing clinical disease progression measures in primary PMS patients. The results for Rituximab were not completely reassuring and only showed significant changes for some endpoints on MRI and clinical measures. Natalizumab decreased the relapse rate and improved MRI features for secondary PMS patients, but not clinical endpoints. The studies on Alemtuzumab treatment revealed conflicting outcomes, with improvements observed in MRI endpoints but clinical worsening in patients. Additionally, among the studied adverse events, upper respiratory infections, urinary tract infections, and nasopharyngitis were frequently reported. CONCLUSION:
