Abstract:
Antibody-drug conjugates (ADCs) have revolutionized precision oncology by enabling targeted drug delivery with improved therapeutic indices. Among these, deruxtecan (DXd)-based ADCs have demonstrated remarkable efficacy across a range of cancers, particularly in tumors expressing human epidermal growth factor receptor 2 (HER2), human epidermal growth factor receptor 3 (HER3), and trophoblast cell surface antigen 2 (TROP2), including breast, lung, gastric, and other solid tumors. DXd, a potent topoisomerase I inhibitor, enhances the cytotoxic potential of ADCs through a cleavable and stable linker and a high drug-to-antibody ratio that ensures optimal drug release. The clinical success of trastuzumab DXd (Enhertu®) and datopotamab DXd (Datroway®), along with the ongoing development of patritumab DXd, has expanded the therapeutic potential of ADCs. However, challenges remain, including toxicity, resistance, and manufacturing scalability. This review discusses the mechanisms of action, clinical progress, and challenges of DXd-based ADCs, highlighting their transformative role in modern oncology and exploring future directions to optimize their efficacy and accessibility.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy.
