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.

More Inclusion & Exclusion Criteria
- - Diagnosis of Primary Progressive Multiple Sclerosis (PPMS) or Relapsing Multiple Sclerosis (RMS) according to the revised McDonald 2017 criteria (Thompson et al.
- - Expanded Disability Status Scale (EDSS) score, 0-6.5, inclusive, at screening.
- - Absence of relapses for 30 days prior to the screening visit.
- - For the dose escalation phase for participants pretreated with ocrelizumab (Group A): treatment with IV ocrelizumab for at least 1 year prior to screening (i.e., at least two 600-mg doses of ocrelizumab separated by 24 weeks) - For women of childbearing potential: agreement to remain abstinent or use acceptable contraceptive methods during the treatment period and for 6 months after the final dose of ocrelizumab.
- - For female perticipants without reproductive potential: Women may be enrolled if post-menopausal unless the participant is receiving a hormonal therapy for her menopause or if surgically sterile (i.e., hysterectomy, complete bilateral oophorectomy).
- - MS disease duration of more than 15 years for participants with an Expanded Disability Status Scale (EDSS) score <2.0 at screening.
- - Known presence of other neurologic disorders that may mimic MS, including, but not limited to, the following: - History of ischemic cerebrovascular disorders (e.g., stroke, transient ischemic attack) or ischemia of the spinal cord.
- - History or known presence of Central Nervous System (CNS) or spinal cord tumor (e.g., meningioma,glioma) - History or known presence of potential metabolic causes of myelopathy (e.g., untreated vitamin B12 deficiency) - History or known presence of infectious causes of myelopathy (e.g., syphilis, Lyme disease, human T-lymphotropic virus 1, herpes zoster and myelopathy.
- - History of genetically inherited progressive CNS degenerative disorder (e.g., hereditary paraparesis and mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke syndrome) - Neuromyelitis optica.
- - History or known presence of systemic autoimmune disorders potentially causing progressive neurologic disease (e.g., lupus, anti-phospholipid antibody syndrome, Sjögren syndrome, Behçet disease, sarcoidosis).
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
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.

Arms & Interventions
Experimental: Group A: Cohorts A1-A4
Participants (participants pretreated with ocrelizumab) will receive a single injection of subcutaneous (SC) ocrelizumab co-mixed with rHuPH20 in the abdomen. For every new dose level, recruitment will be staggered by enrolling 1 participant in each cohort followed by a 48-hour waiting period to review safety and tolerability data by the Safety Monitoring Committee (SMC) prior to enrolling subsequent participants in the same cohort. Currently, the planned dose escalation steps for patients who enroll in Group A are as follows: Cohort A1: 40 mg of SC ocrelizumab Cohort A2: 200 mg of SC ocrelizumab Cohort A3: 600 mg of SC ocrelizumab Cohort A4: 1200 mg of SC ocrelizumab
Experimental: Group A: Cohort A5
In the non-randomized subphase, participants will receive a single SC injection of ocrelizumab co-mixed with rHuPH20 in the abdomen.
Experimental: Group A: Cohort AA
Participants will receive a single 600-mg dose ocrelizumab by intravenous (IV) infusion
Experimental: Group B: Cohorts B1-B4
Ocrelizumab treatment- naive participants will receive a minimum of 3 patients in Cohort B will receive a single SC injection of ocrelizumab co-mixed with rHuPH20 in the abdomen. Cohort B1: 40 mg of SC ocrelizumab Cohort B2: 200 mg of SC ocrelizumab Cohort B3: 600 mg of SC ocrelizumab Cohort B4: 1200 mg of SC ocrelizumab
Drug: - Ocrelizumab
Administered by subcutaneous Injection
Drug: - Ocrelizumab
Administered by Intravenous (IV) Injection
Drug: - rHuPH20
Administered in a 2-mL glass vial as a sterile, single-use, injectable liquid to be manually mixed with SC ocrelizumab
