Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Trastuzumab deruxtecan is a HER2-targeted antibody-drug conjugate (ADC). The antibody binds to HER2 on tumor cells, leading to internalization and intracellular release of the topoisomerase I inhibitor payload (DXd), which causes DNA damage and apoptosis.
Baloxavir marboxil is a prodrug that is converted to baloxavir acid, which inhibits the cap-dependent endonuclease activity of the influenza virus polymerase acidic protein, thereby preventing viral mRNA transcription and replication.

40 mg orally once as a single dose; for patients weighing ≥80 kg, 80 mg orally once as a single dose.

Terminal elimination half-life: 12 hours; clinical context: allows twice-daily dosing in most patients; renal impairment prolongs half-life up to 24 hours
The terminal elimination half-life of baloxavir marboxil is approximately 79.1 hours (range 53–107 hours), supporting single-dose therapy for influenza.
Renal: 60% unchanged; biliary/fecal: 30% as metabolites; 10% other routes
Baloxavir marboxil is primarily excreted via feces (80.1%) and urine (14.7%) after oral administration, with <1% as unchanged drug in urine.
