APL-1092
APL-1092 is an EEVC linker-payload conjugate composed of exatecan, a stabilizer that prevents premature payload release, and a cleavage substrate for cathepsin B. APL-1092 resists premature payload release mediated by human neutrophil elastase and carboxylesterase, maintains payload stability in mouse plasma, and retains cathepsin B-mediated cleavage activity in target cells. APL-1092 exhibits dose-dependent tumor growth inhibition in xenograft mice. APL-1092 can be used in gastric cancer-related research.

Animal Model:NOD.CB17 homozygous[1]
-
Dosage:1.25 mg/kg; 2.5 mg/kg; 2.5 mg/kg; 10 mg/kg
-
Administration:i.v.; once every 4 days; 11 days
-
Result:Showed pronounced antitumor activity with a dose-dependent tumor-inhibitory effect.
Demonstrated substantial therapeutic efficacy at 2.5 mg/kg (AJICAP, DAR = 2, ADC (7)).
Showed superior tumor inhibitory effects compared to trastuzumab-deruxtecan when normalized to incorporated payload amount (AJICAP, DAR = 2, ADC (7)).
Showed significant tumor growth inhibitory effects at both 1.25 mg/kg and 2.5 mg/kg (interchain-break, DAR = 8, ADC (9)).
