Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an uncontrolled, prospective, observational cohort study to assess the function of meningeal lymphatic drainage and dynamics of immune cells in patients with relapsing multiple sclerosis (RMS) or Neuromyelitis optica spectrum disorder (NMOSD) after receiving ofatumumab treatment over an observational period of 12 months.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an uncontrolled, prospective, observational cohort study in patients with RMS or NMOSD who will receive ofatumumab treatment over an observational period of 12 month. Ofatumumab was administrated 20mg by subcutaneous injection on Days 1, 7 and 14 for initial loading, followed by monthly infusion up to 12 months. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) will be performed to assess meningeal lymphatic flow in participants before and after ofatumumab treatment.The change of immune cell landscape in RMS or NMOSD patients after receiving ofatumumab treatment will be monitored by mass cytometry (CyTOF). Assessments also include clinical assessments( clinical relapse rate and EDSS score) and MRI assessments (T2 lesion load, T1 gadolinium enhancing lesion number).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Ofatumumab

17 RMS patients and 17 NMOSD patients prescribed with Ofatumumab will be enrolled after informed consent.

Ofatumumab

Intervention Type DRUG

There is no treatment allocation. Patients with MS or NMOSD administered Ofatumumab by prescription will be enrolled. Participants will receive 20mg ofatumumab (20 mg/0.4 ml) by subcutaneous injection. Ofatumumab is administrated at baseline, Day 7, Day 14 and monthly thereafter until the end of the study.
