Objective: To develop L1CAM-targeted antibody-drug conjugates (ADCs) using high-affinity monoclonal antibodies and assess their therapeutic potential against metastatic cancer.
Summary: L1CAM ADCs conjugated with the potent payload PNU-159682 achieved strong cytotoxicity, tumor regression, and prolonged survival in models of metastatic breast and lung cancer. Safety studies indicated a favorable therapeutic window for clinical translation.
Usage: FabFc-ZAP Human (IT-65) was used to evaluate antibody internalization. FabFc-ZAP was incubated with L1CAM candidate antibodies or isotype control and applied to L1CAM-HEK293T cells, with viability measured after five days.
