About
The main purpose of this study is to assess the bioequivalence of ocrelizumab SC test formulation to the marketed ocrelizumab SC reference formulation in participants with either relapsing multiple sclerosis (RMS) or primary progressive multiple sclerosis (PPMS). The study consists of 2 phases: a controlled phase, where participants in each group will receive one dose of test or reference formulation and a continuation phase, where all participants in both groups will receive ocrelizumab SC test formulation.

- History of confirmed or suspected progressive multifocal leukoencephalopathy (PML)
- History of cancer, including hematologic malignancy and solid tumors, within 10 years of screening
- Immunocompromised state
- Sensitivity or intolerance to any ingredient (including excipients) of ocrelizumab
- History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies
- Any concomitant disease that may require chronic treatment with systemic corticosteroids or immunosuppressants during the course of the study
- Significant, uncontrolled disease, such as cardiovascular, pulmonary, renal, hepatic, endocrine or gastrointestinal, or any other significant disease that may preclude participation in the study
- Lack of peripheral venous access
- Previous treatment with cladribine, atacicept, and alemtuzumab
- Any previous treatment with bone marrow transplantation and hematopoietic stem cell transplantation
