This study will also look at whether an elevated serum neurofilament light (NfL) level predicts enhanced benefit from a switch to ofatumumab.

                This study will evaluate whether ofatumumab is excreted at quantifiable levels and at which concentrations in breast milk of lactating women with RMS). The study will include lactating mothers who plan to breastfeed and initiate/re-initiate ofatumumab 2-24 weeks post-partum.
