BRIUMVI vs CAMPATH
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.
Alemtuzumab is a recombinant humanized monoclonal antibody that binds to CD52, a cell surface antigen expressed on B and T lymphocytes, NK cells, monocytes, and macrophages. Binding induces antibody-dependent cell-mediated cytotoxicity and complement-mediated lysis, resulting in prolonged lymphocyte depletion.
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.
12 mg/day intravenously over 2 hours, administered for 5 consecutive days (total 60 mg). For patients with relapsed/refractory chronic lymphocytic leukemia (CLL), the recommended dose is 3 mg/day intravenously on day 1, 10 mg/day on day 2, and 30 mg/day on day 3 (dose escalation), followed by 30 mg/day three times per week on alternate days for up to 11 weeks (total cumulative dose up to 640 mg).

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.
Terminal half-life approximately 12 days (range 6-21 days) after repeated doses, supporting weekly dosing in CLL.
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.
Clearance via opsonization and degradation in reticuloendothelial system; negligible renal or biliary excretion (<1% unchanged).
