9-month Study to Assess the Efficacy of Ofatumumab on Microglia in Patients With Relapsing Forms of Multiple Sclerosis

Summary

We aim to assess the effect of Ofatumumab on microglial activation using \[F-18\]PBR06 PET in MS patients in relation to changes in serum markers, MRI abnormalities and clinical impairment longitudinally over 9 months. Specific Aims: Specific Aim 1: To determine the effect of Ofatumumab on microglial activation in MS over 9 months. Specific Aim 2: To determine the time course of effect of Ofatumumab on microglial activation and its relationship with peripheral B-cell depletion, serum neurofilament light (sNfL) chain and glial-fibrillary acid protein (GFAP) levels and other serum biomarkers Specific Aim 3: To determine the relationship of PET changes following Ofatumumab initiation with 3T MRI changes and clinical parameters.
