MONJUVI vs VOYXACT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
MONJUVI (tafasitamab-cxix) is a humanized Fc-engineered CD19-directed cytolytic monoclonal antibody. It binds to CD19 antigen on the surface of pre-B and mature B lymphocytes, and upon binding, facilitates antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP).
GABAA receptor positive allosteric modulator; a neuroactive steroid that potentiates GABAergic inhibition.
3 mg/kg intravenously over 60 minutes every 2 weeks until disease progression or unacceptable toxicity.
Adults: 200 mg orally once daily with food.

Terminal half-life: approximately 17 days (range 11-27 days). This supports a dosing interval of every 2 weeks, as steady state is reached by approximately 70 days.
Terminal elimination half-life approximately 37 hours (range 24-51 hours), supporting once-daily dosing with steady-state achieved in 5-8 days.
Monjuvi (tafasitamab-cxix) is a monoclonal antibody primarily catabolized into small peptides and amino acids. No specific data on renal or biliary excretion; minimal intact drug excreted in urine or feces. Expected to undergo general protein degradation.
Primarily hepatic metabolism via CYP3A4, with 53% of the dose excreted in feces (mainly as metabolites) and 27% in urine (mostly as metabolites); less than 1% excreted unchanged in urine.
