Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adrenocorticolytic agent; causes adrenal cortical necrosis and suppresses adrenal steroidogenesis, especially glucocorticoids and mineralocorticoids.
Atezolizumab is a humanized monoclonal IgG1 antibody that binds to PD-L1, blocking its interaction with PD-1 and CD80 receptors, thereby reversing PD-L1-mediated inhibition of T-cell activation and restoring anti-tumor immune responses.
Oral, initial dose 2-6 g/day divided in 3-4 doses, increase gradually to 8-10 g/day. Maximum dose 18 g/day.
800 mg intravenously every 2 weeks; or 1200 mg intravenously every 3 weeks; or 1680 mg intravenously every 4 weeks.

18-159 days; clinical context: during chronic therapy, steady-state may not be reached for 3-6 months.
Terminal elimination half-life is approximately 27 days (range: 20–35 days). This long half-life supports every-3-week dosing and reflects slow clearance typical of IgG1 antibodies.
Primarily renal excretion of metabolites; about 10% as unchanged drug. Biliary/fecal excretion accounts for <5%.
Tecentriq (atezolizumab) is a monoclonal antibody; elimination occurs via intracellular catabolism into amino acids. No renal or biliary/fecal excretion of intact drug. 0% unchanged in urine or feces.
