Ofatumumab, a fully humanized anti-CD20 antibody, reduced disease activity and disability progression in Chinese patients with relapsing multiple sclerosis. Among 38 treatment-naïve patients, the annualized relapse rate fell from 0.27 to 0.05, and the median disability score dropped from 2.50 to 2.00 after 12 months. Among 59 patients who switched from oral therapies (teriflunomide, siponimod, fingolimod, dimethyl fumarate) due to disease progression, relapse, or MRI activity, the relapse rate decreased from 0.45 to 0.08 and disability scores improved from 2.00 to 1.00. No new MRI lesions, relapses, or serious adverse events occurred in either group.
