Who may not be able to join:
- People with a known allergy or intolerance to the study medications (rituximab or ocrelizumab), gadolinium-based MRI contrast dye, or corticosteroids (steroid medicines)
- People diagnosed with primary progressive MS (a form of MS that worsens steadily from the start without relapses)
- People diagnosed with non-active secondary progressive MS (a form of MS that has progressed but without recent relapses or new inflammation)
- People with certain ongoing infectious diseases, including tuberculosis, chickenpox/shingles virus (VZV), hepatitis, or HIV, or those who test positive for hepatitis B surface antigen or hepatitis C at the screening visit
- People with a history of confirmed inflammatory bowel disease such as Crohn's disease or ulcerative colitis
- People with a current or past psychiatric illness, intellectual disability, or cognitive difficulties that would make it hard to give informed consent or follow the study procedures
- People with a heart condition that means treatment with ocrelizumab or rituximab is not medically advisable, according to the official prescribing information
- People with an active cancer, or a past cancer history that means treatment with ocrelizumab or rituximab is not medically advisable, according to the official prescribing information
- People with a low white blood cell count below a specific level, unless it is caused by a current medication and the count returns above the required level before the study begins (confirm with trial site)
- People with a low platelet (blood clotting cell) count below a specific level
- People with elevated liver enzyme levels (ALAT and/or ASAT) more than twice the upper limit of the normal range
- People with a blood creatinine level above a specific level, which may indicate reduced kidney function (confirm with trial site)
- People with elevated bilirubin levels in the blood above the normal range
- People with immunoglobulin G (IgG, a type of immune protein) levels below the lower limit of normal
- People who are pregnant or breastfeeding
- Women who are able to become pregnant and are unwilling or unable to use highly effective contraception throughout the study and for at least three months after the last dose
- People who have previously had a serious or life-threatening reaction during an infusion of ocrelizumab or rituximab

- People currently taking systemic (whole-body) immune-suppressing medications, other than steroids used for MS relapse treatment
- People currently taking part in another clinical drug or device trial, or who finished another such trial less than 30 days ago (people in observational studies only may still be eligible)
