Abstract
AbstractBackgroundOfatumumab is the first monoclonal antibody developed specifically for treating relapsed multiple sclerosis (RMS). This disease (Multiple Sclerosis) includes relapsing–remitting multiple sclerosis (RRMS), a chronic autoimmune illness that affects the central nervous system (CNS), including the brain and spinal cord. The purpose of this study is to determine whether Ofatumumab is efficacious and safe in the treatment of relapsing–remitting multiple sclerosis.MethodsAn analysis of studies comparing Ofatumumab with placebo in people with relapsing‐remitting multiple sclerosis was done in accordance with PRISMA guidelines. We looked up information in MEDLINE, SciSearch, BIOSIS Previews, Derwent Drug File, Embase, and International Pharmaceutical Abstracts. In patients with relapsing–remitting multiple sclerosis, randomized double‐blind and non‐randomized trials contrasting Ofatumumab with placebo were found by two independent investigators. Utilizing Review Manager 5.4.1, data were examined. The main results were total gadolinium‐enhancing (Gd+) T1 lesions, annualized relapse rate, and new or expanding total T2 lesions. Secondary outcomes concentrated on general adverse events and adverse events related to infections.ResultsThree studies were included involving 334 patients, and the meta‐analysis indicated that Ofatumumab showed good efficacy and safety in patients with relapsing forms of multiple sclerosis. The annual rate of relapse was significantly reduced by Ofatumumab (OR 0.51; 95% CI 0.27, 0.98; P = 0.04). Ofatumumab reduced the number of gadolinium‐enhancing (Gd+) T1 lesions per scan (Mean difference −0.59; 95% CI −0.63, −0.55; P < 0.05). Ofatumumab treatment decreased new or enlarging total T2 lesions significantly (Mean difference −1.03; 95% CI −1.29, −0.76; P < 0.05). Infection‐related adverse effects were seen more frequently with Ofatumumab shown by the odd ratio 0.48; 95% CI 0.22, 1.04; P = 0.06. Infection is, thus, a major limitation to its use.ConclusionThe meta‐analysis indicated that Ofatumumab is efficacious and safe for patients with relapsing forms of multiple sclerosis.
