KEYTRUDA vs TEVIMBRA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Pembrolizumab is a humanized monoclonal antibody that binds to the programmed death-1 (PD-1) receptor and blocks its interaction with PD-L1 and PD-L2, releasing PD-1 pathway-mediated inhibition of the immune response, including antitumor immune responses.
Tevimbra (tislelizumab) is a humanized monoclonal antibody that binds to the programmed death-1 (PD-1) receptor and blocks its interaction with ligands PD-L1 and PD-L2, thereby releasing PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response. This restores T cell effector function and enhances immune-mediated killing of tumor cells.
KEYTRUDA (pembrolizumab) 200 mg intravenously every 3 weeks or 400 mg intravenously every 6 weeks. Infuse over 30 minutes.
200 mg intravenously every 3 weeks or 400 mg intravenously every 6 weeks.

Terminal elimination half-life is approximately 22 days (range 14–27 days) based on population pharmacokinetics, consistent with its IgG4 monoclonal antibody structure. This long half-life supports the every-3-week or every-6-week dosing interval.
Terminal half-life approximately 21.5 days (range 14–30 days), supporting every-3-week dosing interval.
Pembrolizumab is not metabolized; elimination occurs primarily via catabolism to small peptides and amino acids. Less than 1% is excreted unchanged in urine. No significant biliary or fecal elimination.
Primarily degraded via catabolism; no significant renal or biliary excretion. Elimination via reticuloendothelial system.
