TQB6411

The Phase Ib stage of this study primarily aims to evaluate the tolerance and safety of TQB6411 Injection in subjects with recurrent or metastatic Esophageal cancer who have previously failed treatment with PD-1/PD-L1 monoclonal antibodies combined with platinum-based chemotherapy. The Phase II stage primarily aims to evaluate the efficacy of TQB6411 Injection in this same patient population.

TQB6411 for injection is an antibody-conjugated drug (ADC) targeting EGFR/c-Met. After injecting blood intravenously, the antibody part of this product binds to the surface of EGFR and c-Met on tumor cells to block the activation of EGFR and c-Met signaling pathways. The ADC is enzymatically transported to the lysosome. The linker releases toxins after enzyme cleavage, resulting in DNA damage and cell death. TQB6411 for injection is intended for the treatment of advanced malignant tumors.
