Global Clinical Landscape & Future Outlook
The race for TACSTD2/TROP2 therapeutics is intensifying, with major players shifting focus from traditional mAbs to Antibody-Drug Conjugates (ADCs) and next-generation immune engagers. First-generation therapies such as sacituzumab govitecan (Trodelvy) have achieved blockbuster status in triple-negative breast cancer (TNBC) and urothelial carcinoma, while datopotamab deruxtecan (Dato-DXd) advances in NSCLC and HR+ breast cancer. The next wave of R&D targets optimized payload delivery (e.g., topoisomerase I inhibitors, SN-38), novel bispecific formats (TROP2 x HER2, TROP2 x EGFR), refined safety profiles to minimize off-target epithelial toxicity, and combination immunotherapy regimens to overcome resistance.
