Brief Summary
This is a multicenter Phase 1b/2 clinical trial investigating the efficacy and safety of a combination regimen of Gemcitabine, Cisplatin, Nab-paclitaxel, and Tislelizumab in treatment-naïve patients with unresectable, locally advanced, or metastatic biliary tract cancers (BTC), including intrahepatic cholangiocarcinoma, extrahepatic cholangiocarcinoma, and gallbladder cancer. The Phase 1b portion aims to determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of Nab-paclitaxel in combination with Gemcitabine, Cisplatin, and Tislelizumab. In the Phase 2 portion, the study will evaluate the Objective Response Rate (ORR) as the primary endpoint, with additional assessments of Overall Survival (OS), Progression-Free Survival (PFS), Disease Control Rate (DCR), and Quality of Life (QoL). Safety and tolerability will also be closely monitored. This study seeks to leverage the stromal-disrupting effect of Nab-paclitaxel and the immune checkpoint blockade effect of Tislelizumab, combined with the established chemotherapy backbone of Gemcitabine and Cisplatin, to enhance treatment outcomes for BTC patients. The study will enroll patients across three medical centers in South Korea, including CHA Bundang Medical Center, Haeundae Paik Hospital, and Seoul National University Bundang Hospital.
