FZ-AD005
Based on 1 Customer Validation
FZ-AD005 is an antibody-drug conjugate (ADC) that selectively targets DLL3, generated by conjugating the anti-DLL3 antibody FZ-A038 (HY-P990896) with a dipeptide linker (Val-Ala) and DXd (HY-13631D). FZ-AD005 binds human DLL3 with a Kd of 58.3 pM. FZ-AD005 binds cell-surface DLL3 and mediates internalization, followed by lysosomal cathepsin cleavage to release the payload DXd, which induces DNA double-strand breaks, cell cycle arrest, and apoptosis through inhibition of topoisomerase TopI, and exhibits a bystander killing effect on adjacent DLL3-negative cells. FZ-AD005 can be used for research on small cell lung cancer and human neuroendocrine prostate cancer.

In Vitro
FZ-AD005 (100 μg/mL; 7 d) is highly stable in human plasma, releasing only about 0.7% of DXd[1] after 7 days of incubation at 37℃.
FZ-AD005 (200 pmol; 48 h) rapidly internalizes into DLL3-expressing cells within 30 minutes, traffics to lysosomes, and releases DXd in a time-dependent manner over the 48-hour test period[1].

Parmacokinetics
In Vivo
FZ-AD005 (1.5-6 mg/kg; i.v.; single dose) at doses of 1.5, 3 and 6 mg/kg induces complete tumor growth inhibition in male NOD/SCID mice inoculated with NCI-H660 NEPC xenografts[1].
FZ-AD005 (1-5 mg/kg; i.v.; once weekly; 2 total administrations) induces significant tumor growth inhibition in female BALB/c nude mice bearing NCI-H82 SCLC xenografts; at intravenous doses of 1, 3 and 5 mg/kg given once weekly for 2 total administrations, its TGI ranges from 76.52% to 97.13%[1].
FZ-AD005 (1.5-6 mg/kg; i.v.; single administration) induces potent to complete tumor growth inhibition in mice bearing SCLC LU-5236 PDX, with TGIs ranging from 98.51% to 100.00% across different dose groups on day 21 post-administration[1].
