About this trial

Biliary tract carcinoma (BTC), including cholangiocarcinoma and gallbladder cancer, is a highly aggressive digestive system malignancy with limited treatment options after failure of first-line standard chemotherapy.

This open-label, single-arm, Phase II exploratory study aims to evaluate the efficacy and safety of Becotatug Vedotin combined with Pucotenlimab in patients with EGFR-positive advanced BTC who have failed first-line therapy. Participants will receive the combination regimen until the occurrence of disease progression, unacceptable toxicity, withdrawal of informed consent, death, pregnancy, investigator's decision to discontinue treatment, or study termination, whichever occurs first.The primary endpoint is objective response rate (ORR) assessed per RECIST v1.1. Secondary endpoints include progression-free survival (PFS), overall survival (OS), disease control rate (DCR), duration of response (DOR), and safety.
