Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

|Relapsing Multiple Sclerosis|
Design: This is an open-label, observational, prospective, 9-month follow-up study to assess the efficacy of ofatumumab on microglia pathology in patients with MS, as measured by changes in microglial activation in the lesional and non-lesional, normal appearing white matter, cortical and subcortical grey matter, and peri-plaque area of chronic lesions in the brain. Initial Visit: During the first visit, subjects will be adminsitered the screening questionnaire (if that has not already been done over telephone). Subjects will review and eventually sign the consent form. They will be administered a physical examination, clinical assessment and standardized questionnaires for cognitive testing and/or other co-morbidities. In addition, blood samples will be drawn for genotype testing, infection screening, complete blood count and liver function test. Demographics, physical examinations and neurologic assessments will be conducted at Partners MS Center, Brigham and Women's Hospital, 60 Fenwood Road, Boston, MA 02115. Genotype Testing: Blood sample drawn on the initial screening visit will be used to obtain genomic DNA for genotyping for polymorphism within the TSPO gene on chromosome 22q13.2, using a Taqman assay. High affinity and medium affinity binders will be included in the study, whereas low affinity binders will be excluded from the study. PET Scanning: For this study, all subjects will undergo five separate visits for [F-18]PBR06 PET scans, one visit before starting Ofatumumab treatment (day 0 baseline) and four more visits at approximately 5, 28, 90 and 273 days after initiating treatment. During the PET scan visits, all women subjects of child bearing age will undergo a stat quantitative serum hCG pregnancy test and only women with a negative test will undergo the radiopharmaceutical injection. The radiotracers will be produced using standardized procedures. At the time of imaging, the subjects will be positioned in the gantry of a high-resolution PET/CT camera. Head alignment will be made, relative to the canthomeatal line, using projected laser lines whose positions are known with respect to the slice positions of the scanner. A head support apparatus will be used to minimize head motion. Dynamic data over 120 minutes for PET quantification will be acquired, according to previously described methods for the tracer. MRI Scanning: All subjects will undergo five 3T brain MRIs with and without contrast, one before starting Ofatumumab treatment (day 0 baseline) and four more at 5, 28, 90 and 273 days after initiating treatment. MRI visits may precede or follow the PET scan visits within 2-3 days of each other. All women will be queried about their pregnancy status, use of contraception and last menstrual period. If a woman is of child bearing potential, she will undergo a urine pregnancy test. Subjects will undergo intravenous gadolinium contrast administration, during all visits. Hence, all women of child bearing potential will undergo urine pregnancy testing for this study. Clinical Follow-up Visits: Subjects will come in for five clinical visits, one visit before starting Ofatumumab treatment (day 0 baseline) and four more visits at 5, 28, 90 and 273 days after initiating treatment. However, if the patient meets all inclusion criteria at the screening visit, the screening and baseline visits may occur on the same day. During these visits, subjects will undergo a physical examination, clinical assessment and cognitive assessment using the measures outlined in section e of Study Procedures. A blood sample will be drawn to determine levels of sNfL, GFAP and other serum biomarkers. Visits will be conducted under the supervision of PI and other board-certified neurologists. Any adverse event reported by the patient or observed by the investigator will be recorded and reviewed at each clinical visit. Clinical Data: The following non-imaging, clinical data will be obtained: Expanded Disability Status Scale (EDSS), Timed 25-feet walk (T25W), 9-Hole Peg Test (9HPT), Four component MS Functional Composite (MSFC-4), Symbol-Digit Modality test (SDMT), cognitive and symptom questionnaires, vision testing, Levels of serum biomarkers. Clinical Safety Monitoring: Safety will be assessed at 0, 3, 6, and 9 months of the study including:
- - Pregnancy Testing: All women of childbearing potential will undergo a serum pregnancy test at the screening visit and at each of the following scheduled visits to the hospital.
- - Electrocardiogram (ECG): An ECG will be performed either at the screening visit or on day 0 clinical visit and at the end of the study.
- - Routine labs: Blood samples will be collected at the screening visit and at each visit time point.
- - Samples for total IgM and IgG levels at baseline, 3, 6 and 9 months.
- - Patient diary review.
- - Monthly telephone interview.
Arms & Interventions
Experimental: Subjects diagnosed with relapsing forms of multiple sclerosis
We plan to enroll 10 subjects with relapsing MS. All enrolled subjects will receive Ofatumumab 20 mg every 4 weeks, subcutaneously for 9 months during the study. Loading doses will be administered initially at 1, 7 and 14 days. During the study period, all enrolled subjects will undergo five PET scans using [F-18] PBR06 at 0, 5, 28, 90 and 273 days after starting treatment with Ofatumumab.
Drug: - Ofatumumab
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.
Drug: - [F-18]PBR06
PET radiopharmaceutical. Subjects will undergo [F-18]PBR06-PET (microglial activation).
