Correct answer: E20 mg subcutaneously at weeks 0, 1 and 2, then monthly beginning at week 4

Ofatumumab for relapsing multiple sclerosis is self-administered as 20 mg subcutaneously at weeks 0, 1 and 2; there is no week-3 injection, and monthly maintenance begins at week 4. The intravenous six-monthly schedule describes ocrelizumab rather than ofatumumab. The other schedules are not authorised regimens.
