October 19, 2022 updated by: Chao Zhang, Tianjin Medical University General Hospital

Exploring the Effects of B Cell Depletion With Ofatumumab on Immune Cells and Meningeal Lymphatic Drainage in Patients With Demyelinating Diseases - a Prospective Observational Study

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Ofatumumab
17 RMS patients and 17 NMOSD patients prescribed with Ofatumumab will be enrolled after informed consent.
Drug: Ofatumumab
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from baseline in Time to Peak (TTP) of the meningeal lymphatic vessels in superior sagittal sinus (mLVs-SSS) to the end of study.
Time Frame: Baseline, Up To 12months (End of Study)
The image of mLVs-SSS in participants will be detected by Dynamic contrast-enhanced MRI (DCE-MRI) before and after ofatumumab treatment.MRI images would be analyzed by three radiologists independently, and each of them is blinded to the patients' information. The obtained DCE-MRI data are interpreted semi-quantitatively to generate TTP.
Baseline, Up To 12months (End of Study)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Immune cells landscape over time
Time Frame: Baseline, month 3, month 6, month 12
The dynamics of immune cells in participants will be detected by mass cytometry (CyTOF) before and after ofatumumab treatment.
Baseline, month 3, month 6, month 12
Adjudicated On-trial Annualized Relapse Rate (ARR)
Time Frame: Baseline, Up To 12months (End of Study)
The adjudicated On-trial ARR was computed as the total number of relapses divided by the total number of patient years in the study period. A central independent committee was used to adjudicate all On-trial Relapses as determined by the treating physician. Results reported as adjusted adjudicated On-trial ARR based on a Poisson regression adjusted for randomization strata and historical ARR in 24 months prior to Screening.
Baseline, Up To 12months (End of Study)
Percentage of Participants With Worsening in Expanded Disability Severity Scale (EDSS) Score From Baseline to the end of study
Time Frame: Baseline, Up To 12months (End of Study)
Disease-related disability was measured by the EDSS before and after ofatumumab treatment. The EDSS was an ordinal clinical rating scale that ranges from 0 (normal neurologic examination) to 10 (death) in half-point increments.
Baseline, Up To 12months (End of Study)
Percentage of participants with new lesions by MRI assessments from baseline to the end of study
Time Frame: Baseline, Up To 12months (End of Study)
Magnetic Resonance Imaging (MRI) will be used to measure presence of increase in number of gadolinium enhancing lesions and T2 lesion load. Each MRI scan will be previewed by a local neuroradiologist. The quality of each scan performed will be assessed by a central MRI reading center and evaluated for quality, completeness and adherence to the protocol.
Baseline, Up To 12months (End of Study)
