| Summary: | Antibody–drug conjugates (ADCs) have emerged as a transformative approach in cancer therapy by enhancing tumor targeting and minimizing systemic toxicity compared to traditional chemotherapy. Initially developed with chemotherapy agents as payloads, ADCs have now incorporated alternative payloads, such as immune-stimulating agents, natural toxins, and radionuclides, to improve therapeutic efficacy and specificity. A significant advancement in ADC technology is the integration of Proteolysis Targeting Chimeras (PROTACs), which enable the precise degradation of cellular targets involved in tumorigenesis. This strategy enhances the specificity and precision of cancer therapies, addressing key mechanisms in cancer cell survival. Moreover, incorporating radioactive isotopes into ADCs is an emerging strategy aimed at further improving therapeutic outcomes. By delivering localized radiation, this approach offers the potential to enhance the efficacy of treatment and expand the therapeutic arsenal. Despite these innovations, challenges remain, including dysregulated immune activation, severe adverse effects, and intrinsic immunogenicity of some agents. These emerging issues highlight the ongoing need for optimization in ADC therapy. This review summarizes the latest developments in ADC technology, focusing on novel payloads, PROTAC integration, and the potential for combining ADCs with other therapeutic modalities to refine cancer treatment and improve patient outcomes. |
