• A study of 103 MS patients found that 34% experienced end-of-dose phenomena (EOD) with ofatumumab, impacting their quality of life.
• EOD was associated with higher baseline disability, longer disease duration, and older age, highlighting the need for careful monitoring.
• Fatigue, cognitive impairment, and gait difficulties were the most commonly reported EOD symptoms among patients on ofatumumab.
• Compared to ocrelizumab, ofatumumab showed a lower incidence of the wearing-off effect in a separate study, suggesting potential differences in B-cell depletion.
