Ublituximab, sold under the brand name Briumvi, is a medication used to treat multiple sclerosis.[1] Specifically it is used for clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease.[1] It is given by injection into a vein.[1]

Common side effects include infusion reactions and upper respiratory tract infections.[1] Other side effects may include infections and low immunoglobulins.[1] Use during pregnancy may harm the baby.[1] It is a monoclonal antibody directed against CD20.[1]

Ublituximab was approved for medical use in the United States in 2022.[1] In 2023 it received a positive opinion by regulators in Europe.[2] In the United States it costs about 64,000 USD per year as of 2023.[3]

Medical uses

Ublituximab is used to treat relapsing forms of multiple sclerosis.[1][4] It decreases relapses per year by about 50%.[2]


The initial doses are generally 150 mg followed two weeks later by 450 mg.[1] Further doses of 450 mg are than given every 24 weeks.[1]


Researchers demonstrated the efficacy of ublituximab in two randomized, double-blind, double-dummy, parallel group, active comparator-controlled clinical trials of identical design, in participants with relapsing forms of multiple sclerosis treated for 96 weeks.[4] Participants were randomized to receive either ublituximab or teriflunomide, the active comparator.[4] The primary outcome of both studies was the annualized relapse rate over the treatment period.[4] In both studies, ublituximab significantly lowered the annualized relapse rate compared to teriflunomide.[4]
