In a CLDN18.2-high patient-derived xenograft (PDX) PC tumor model, increasing doses of TPX-4589 demonstrated superior tumor growth inhibition compared to gemcitabine and LM-102, a compound with identical anti-CLDN18.2 mAb component as LM-302, and similar efficacy to LM-102 + gemcitabine in combination. TPX-4589, a novel CLDN18.2-targeting ADC, showed potent inhibitory effects on tumor cell proliferation in vitro and reduced tumor volume in both high- and low-expressing CDLN18.2 tumor models, with superior internalization and efficacy to zolbetuximab in a GC tumor model. These data suggest that TPX-4589 is a promising therapeutic candidate that warrants further investigation in clinical studies.
