Advanced Biliary Tract Cancer(BTC)

This is a single-arm, Phase II, multicenter clinical trial evaluating sacituzumab tirumotecan in patients with TROP2-positive advanced biliary tract cancer who have experienced disease progression after, or intolerance to, at least one prior line of systemic therapy. Eligible participants will receive sacituzumab tirumotecan monotherapy. The primary objective is to evaluate objective response rate as assessed by the investigator according to RECIST version 1.1. Secondary objectives include evaluation of progression-free survival, overall survival, and safety. Exploratory analyses will assess the association between TROP2 protein expression and clinical efficacy, as well as potential mechanisms of resistance.

This study is for patients with advanced bile duct or pancreatic cancer who are experiencing pain from their disease. The purpose of this research is to learn about the effects of combining a standard pain relief treatment (Celiac Plexus Block) with standard first-line cancer drugs. Patients in this study will receive the Celiac Plexus Block procedure, which is intended to reduce pain, and will then begin their standard cancer medication regimen. Researchers will observe and compare how well this combined approach works to control pain and the cancer itself, and will monitor for any side effects. Participation in this study involves being followed by the research team for up to 2 years to track health outcomes. The goal is to see if starting cancer treatment together with this specialized pain management technique is more helpful for patients compared to what is already known about the standard treatments alone.

This is a prospective, non-randomized, open-label, single-center phase II clinical trial. It aims to evaluate the efficacy and feasibility of using patient-derived tumor organoid drug sensitivity testing (ODST) to guide personalized systemic therapy for patients with unresectable biliary tract cancers (BTC). A total of 88 eligible patients will be enrolled and grouped based on patient preference into either the ODST-guided group or the control group (standard therapy). Tumor tissues obtained via biopsy will be used to establish organoid cultures. Drug sensitivity testing will be performed on a panel of approved regimens (including GC, GEMOX, Durvalumab+GC, Pembrolizumab+GC, and Toripalimab+Lenvatinib+GEMOX) to identify the most effective treatment. Patients for whom organoid testing fails or results are unavailable within one month will receive standard therapy. The primary endpoints are Objective Response Rate (ORR) and Progression-Free Survival (PFS). Secondary endpoints include Overall Survival (OS) and safety profiles. The study seeks to provide a novel, personalized treatment strategy to improve outcomes for patients with advanced BTC.
