Predicting how biliary tract tumors respond to immunotherapy

Prospective Observational Study on Prediction of Response to First-line Immunotherapy in Patients With Biliary Tract Tumors

Zhejiang Cancer Hospital · NCT06048289

This study is testing if certain markers in tumor and blood samples can help predict how well immunotherapy will work for people with advanced biliary tract tumors.

What this trial studies

This observational study aims to identify biomarkers that can predict the effectiveness of immunotherapy in patients with unresectable advanced or metastatic biliary tract tumors. Participants will receive PD-1/PD-L1 inhibitors combined with chemotherapy as their first-line treatment. The study will involve collecting tumor tissues through biopsies and analyzing them using genomic and transcriptomic techniques, along with blood and fecal samples to assess various biomarkers. The goal is to explore and identify predictive biomarkers that could guide future immunotherapy treatments for these tumors.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with unresectable advanced or metastatic biliary tract tumors confirmed as adenocarcinoma.

Not a fit: Patients with other active malignant tumors or those unable to provide necessary biological samples may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective treatment strategies for patients with biliary tract tumors.

How similar studies have performed: While there have been studies exploring biomarkers in other cancers, this specific approach in biliary tract tumors is novel and has not been extensively tested.
