BRIUMVI vs ZINPLAVA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BRIUMVI (ublituximab) is a recombinant, chimeric, humanized monoclonal antibody that binds to CD20, a transmembrane antigen expressed on pre-B and mature B lymphocytes. Binding to CD20 results in antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC), leading to B-cell depletion.
Bezlotoxumab is a human monoclonal antibody that binds to Clostridioides difficile toxin B, neutralizing its activity and preventing damage to colonic epithelial cells.
BRIUMVI (ublituximab) 150 mg administered as an intravenous infusion over 4 hours once weekly for 3 weeks, then 150 mg once every 6 months thereafter.
10 mg/kg intravenously over 60 minutes, single dose.

Terminal elimination half-life is approximately 19-20 days (range 11-30 days) in patients with relapsing multiple sclerosis. The long half-life supports every-6-month dosing.
Mean terminal elimination half-life is approximately 19 days (range 14–22 days), supporting a 6-week dosing interval.
BRIUMVI (ublituximab) is a monoclonal antibody. Elimination occurs via intracellular catabolism and is not excreted renally or fecally in significant amounts. No specific excretion data available.
Primarily eliminated via fecal excretion as unchanged drug (approximately 79% of dose), with minimal renal excretion (about 15% as unchanged drug).
