Disease stage
Relapsing multiple sclerosis diagnosed by the 2017 McDonald criteria. Neurologically stable within 30 days.
Earlier treatment
Must be treated with ocrelizumab at the standard dose in routine care. Must not have had a life-threatening infusion or injection reaction to ocrelizumab.
Biomarker or test result
CD19+ B-cell count must be below 10 cells/µL at screening.
