CLOFARABINE vs VYLOY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clofarabine is a purine nucleoside antimetabolite that inhibits DNA synthesis by reducing intracellular deoxynucleotide triphosphate pools via inhibition of ribonucleotide reductase, and by terminating DNA chain elongation through incorporation into DNA, leading to apoptosis.
VYLOY (zolbetuximab-clzb) is a chimeric IgG1 monoclonal antibody that binds to claudin 18.2 (CLDN18.2), a tight junction protein expressed on the surface of gastric cancer cells. Binding induces antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC), leading to tumor cell death.
52 mg/m^2 intravenously over 2 hours daily for 5 consecutive days, repeated every 28 days.
VYLOY (zolbetuximab-clzb) is administered intravenously at a dose of 800 mg every 2 weeks following a loading dose of 1200 mg on day 1 of cycle 1.
