Abstract

BACKGROUND: Ocrelizumab is an approved MS treatment administered as two 300-mg intravenous infusions 2 weeks apart (Dose 1), each lasting approximately 2.5 hours, followed by single 600-mg infusions every 6 months lasting approximately 3.5 hours. Our objective was to evaluate shorter-duration ocrelizumab infusions in the Phase IIIb open-label SaROD study (NCT03606460).

METHODS: Eligible patients received ocrelizumab 600-mg Dose 2 or 3 infused over approximately 2 hours (Cohort 1) or ocrelizumab 300-mg Dose 1, Infusion 2 over approximately 1.5 hours (Cohort 2). The primary endpoint was the number and proportion of patients experiencing Grade 3-4 infusion-related reactions (IRRs) in Cohort 1. Secondary endpoints included Grade 1-4 IRRs in both cohorts and Grade 3-4 IRRs in Cohort 2.

RESULTS: Mean infusion times decreased by approximately 1.09 and 0.79 hours in Cohorts 1 and 2, respectively, compared with US prescribing information. IRRs, reported by 36% of 141 patients, were mild-to-moderate, with no observed Grade 3-4 IRRs. No IRR-related discontinuations occurred. No serious AEs, deaths, or new safety signals were observed.

CONCLUSION: The IRR rate with ocrelizumab shorter-duration infusions was similar to that observed in the pivotal Phase III trials. Ocrelizumab can be infused over a shorter time without sacrificing patient safety.
