While accelerated approval underscores its therapeutic promise, long-term positioning will depend on confirmatory trials, refinement of biomarker testing, and optimization of patient selection. If validated, this strategy may redefine later-line treatment expectations by aligning cytotoxic payload delivery with biologically enriched disease subsets.
In preclinical studies, B6ADC exhibits potent cytotoxicity in vitro across various TROP2/c-Met-expressing cancer cell lines and superior tumor inhibition in vivo compared with single-target ADC combination, including the clinically approved TROP2 ADC sacituzumab govitecan and c-Met ADC Teliso-V, as well as their combination. Notably, B6ADC eradicates giant tumors with a single dose at a low concentration of 2.2 mg/kg. We present a nanobody-based BsADC that simultaneously targets TROP2 and c-Met, with broad-spectrum antitumor activity, and improves selectivity for tumors with dual-positive or weakly positive antigen expression, offering a promising strategy for treating pancreatic cancer and other TROP2/c-Met-expressing malignancies.
