Briumvi®

ublituximab-xiiy

Quick Facts

Briumvi® is an immunosuppressant monoclonal antibody that targets CD20.

In-clinic intravenous infusion

Given every 24 weeks, following the initial dosing

Relapsing forms of multiple sclerosis (MS) in adults – including clinically isolated syndrome, relapsing-remitting MS, and active secondary-progressive MS

Potential Benefit:

Compared to the oral medication, Aubagio® (teriflunomide) in two identical studies, relapse rate was 0.08 in the Briumvi® group versus 0.19 in the Aubagio group in the first study and 0.09 and 0.18, respectively, in the second.

The mean number of T1 gadolinium-enhancing lesions was 0.02 and 0.01 in the Briumvi® groups versus 0.49 and 0.25, respectively, in the Aubagio groups. The mean number of new or enlarging T2 hypointense lesions was 0.21 and 0.28 in the Briumvi® groups versus 2.79 and 2.83 in the Aubagio groups.

In the two studies, “no evidence of disease activity” (NEDA) was seen in 44.6% and 43%, respectively, of those treated with Briumvi®, versus 15.0% and 11.4%, respectively, of those receiving Aubagio.

Common Potential Side Effects

Infusion-related reactions, infections, headache, nasopharyngitis (cold symptoms), pyrexia (fever), and nausea.

HOW Briumvi® WORKS

Briumvi® (ublituximab-xiiy) is a monoclonal antibody that targets CD20, a protein found on the surface of B cells, and induces B-cell depletion within 24 hours. B cells are white blood cells shown to play a role in MS.

Briumvi® is uniquely designed to lack certain sugar molecules normally expressed on the antibody. Removal of these sugar molecules, a process called glycoengineering, allows for efficient B-cell depletion at low doses.

FDA-Approved

In 2022, Briumvi® was approved for the treatment of relapsing forms of multiple sclerosis (MS) in adults – including clinically isolated syndrome, relapsing-remitting MS, and active secondary-progressive MS.

Potential Side Effects

In studies, the most common adverse event was infusion-related reactions, often causing fever, headache, chills, and/or flu-like symptoms. Other side effects included headache, nasopharyngitis (cold symptoms), pyrexia (fever), and nausea.

Studies also showed that just over half of trial participants experienced infections. Most were related to the respiratory tract, but urinary tract infections and herpes virus infections were seen in smaller percentages of participants.

Serious and life-threatening infections were seen in 5% of study participants taking Briumvi®. Three infection-related deaths occurred with Briumvi®-treated patients. Administration of Briumvi® should be delayed in patients experiencing active infection.

OTHER KEY INFORMATION

Although cases of progressive multifocal leukoencephalopathy (PML) have been reported in patients taking other anti-CD20 antibodies, no cases of PML occurred during the 96-week period. Additionally, no opportunistic infections were reported.

Testing needed prior to and/or during treatment:

  • All patients should be screened for HBV prior to starting Briumvi® and anyone with active HBV should not be given Briumvi®.
  • Results of animal studies suggest that Briumvi® may harm the fetus if given to a pregnant woman. For this reason, women who could become pregnant should be given a pregnancy test prior to starting Briumvi® as well as prior to each infusion. Effective contraception is recommended during treatment with Briumvi® and for six months after discontinuing treatment.
  • Decreased immunoglobulin levels can occur with any B-cell depleting therapy, so quantitative serum immunoglobulins levels should be monitored during treatment, especially in patients with opportunistic or recurrent infections, and after discontinuation of therapy until B-cell repletion.
