Open-label, Observational, Prospective, 9-month Study to Assess the Efficacy of Ofatumumab on Microglia in Patients With Relapsing Forms of Multiple Sclerosis

Brigham and Women's Hospital·interventional·Posted Aug 12, 2020·Updated Jan 27, 2026

In Brief

A Phase 3 clinical trial evaluating Ofatumumab and [F-18]PBR06 for Relapsing Multiple Sclerosis. Completed, enrolled 10 participants across 1 site.

Detailed 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.

Interventions

Ofatumumabdrug

Ofatumumab (OMB157) is a fully human anti-CD20 monoclonal antibody (mAb) self-administered by a once-monthly subcutaneous injection that is in development for MS. Ofatumumab drug product (also referred as OMB157) is formulated as 20 mg/0.4 mL (50 mg/mL) solution for injection, provided in autoinjectors, for subcutaneous administration. The autoinjectors contain a small overfill to allow for a complete withdrawal of the labeled amount (20 mg) of ofatumumab.

[F-18]PBR06drug

PET radiopharmaceutical. Subjects will undergo \[F-18\]PBR06-PET (microglial activation).
