Targeting HER2-positive breast cancer: advances and future directions Certain HER3 mutants have demonstrated oncogenic driver activity in the absence or presence of HER2, and some can confer resistance to EGFR and HER2 directed therapies [9, 11, 13]. Adding cytotoxic payload to HER3-directed mAb can be a promising strategy with enhanced target cell killing efficacy. However, the emergence of acquired resistance to EGFR-TKIs is inevitable, underscoring the importance of a state-of-the-art approach for subsequent treatment. At least one treatment-emergent adverse event (TEAE) was reported for all patients in both trials. PIP (Public Site) Search PIP Page Total Records: 266, Wed Nov 9 21:25:07 GMT 2022 PIP Number Active Substance Conditions / Indications Invented Name In general, the development of ADCs faces the following three challenges: (1) payloads are limited as there are few agents with the subnanomolar range of cytotoxic activity required for ADC payload candidates; (2) drug linker instability may result in the release of the drug into the circulation; and (3) there is a need to achieve higher drug loading (i.e., an increased number of payload molecules per antibody molecule) as this is expected to lead to better efficacy [10].
