Key clinical point: The time to confirmed disability progression (CDP) and serum neurofilament light chain levels (sNfL) was not significantly different in patients with primary progressive multiple sclerosis (pwPPMS), who received treatment with rituximab or ocrelizumab.
Major finding: After a mean follow-up of 18.3 months, rituximab vs. ocrelizumab groups showed no significant difference in the proportion of patients with CDP (30.6% vs. 23.9%; P = .356). The mean sNfL level was not significantly different between the groups ( P = .192).
Study details: The findings come from a multicentric observational study involving 111 pwPPMS who started treatment with ocrelizumab or rituximab.
Disclosures: This study was supported by the Health Institute Carlos III and FEDER funding. Four authors reported receiving travel grants and consulting/speaker fees from various sources.
