CBB-120: A TROP2-targeted dual-payload ADC combining Top1i and ATRi mechanisms demonstrates superior efficacy in preclinical models and improved safety in non-human primates (AACR-NCI-EORTC 2025) - "Among current therapies, Trodelvy® and Datroway® (Dato-DXd) carrying topoisomerase I inhibitors (Top1i) have demonstrated notable clinical benefits. CBB-120, a novel site-specific Fc-silenced dual-payload ADC targeting TROP2, enables targeted delivery of both its Top1i and ATRi payloads to TROP2-expressing tumors, achieving synergistic, highly potent anti-tumor efficacy while minimizing systemic toxicity. Our findings support the continued development of CBB-120 as a promising best-in-class next-gen ADC for TROP2-positive cancers. Our data also emphasizes the improved safety profile of our EGCit linker payload platform, which can be used to address unmet needs in other important tumor types."
