The HER2-targeting ADC SHR-A1811 in HER2-expressing/mutated advanced non-breast solid tumors (STs): Results from the global phase I study (ESMO 2023)
Background SHR-A1811 is a novel ADC composed of trastuzumab (anti-HER2), a cleavable linker, and a topoisomerase I inhibitor payload, with optimized drug-antibody ratio of 6 and strong bystander killing effect.

Safety, tolerability, pharmacokinetics, and antitumor activity of SHR-A1811 in HER2-expressing/mutated advanced solid tumors: A global phase 1, multi-center, first-in-human study (AACR 2023)
Background: SHR-A1811 is an ADC comprised of a humanized anti-HER2 monoclonal antibody (trastuzumab), a cleavable linker, and a DNA topoisomerase I inhibitor payload. SHR-A1811 was well-tolerated and showed promising antitumor activity in heavily pretreated advanced solid tumors.Table 1.
