What this trial studies

This clinical trial evaluates the efficacy and safety of Cadonilimab in combination with Regorafenib and Gem-Cis chemotherapy for patients with advanced biliary tract cancer. The study aims to determine how well this combination therapy works in treating the disease compared to standard treatments. Participants must have a measurable lesion and meet specific health criteria to be eligible for the trial. The study is designed to provide insights into a potentially effective treatment option for this challenging cancer type.

Who should consider this trial

Good fit: Ideal candidates are adults with a confirmed diagnosis of advanced biliary tract cancer who have not received prior systemic treatment.

Not a fit: Patients with mixed ampullary, hepatocellular, or cholangiocarcinoma diagnoses, or those with certain serious health conditions, may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a new therapeutic option for patients with advanced biliary tract cancer.

How similar studies have performed: While this specific combination has not been widely tested, similar approaches in treating biliary tract cancer have shown promise in other studies.
