Phase 3 Study Comparing Rilvegostomig or Durvalumab Plus Chemotherapy as First Treatment for Advanced Biliary Tract Cancer

What this Trial Is About

Researchers are evaluating the safety and effectiveness of rilvegostomig combined with gemcitabine plus cisplatin compared to durvalumab combined with gemcitabine plus cisplatin as a first-line treatment for patients with advanced biliary tract cancer BTC. This phase III, randomized, open-label study aims to improve treatment options for patients with unresectable locally advanced or metastatic BTC who have not received prior therapy for advanced disease. The study focuses on overall survival and other important outcomes over approximately four years. Participants receive either rilvegostomig or durvalumab through intravenous infusion along with chemotherapy drugs gemcitabine and cisplatin. Durvalumab is given every three weeks for up to eight cycles, then every four weeks. Gemcitabine and cisplatin are administered intravenously on Days 1 and 8 of each 21-day cycle. The study compares these two treatment combinations to assess their effects on survival, disease progression, tumor response, and safety. During the study, participants undergo regular assessments including imaging scans like CT or MRI to measure disease status, laboratory tests to evaluate organ function, and evaluations of symptoms and quality of life. Researchers monitor drug levels and immune response markers. The study lasts about four years, with ongoing safety and health status monitoring throughout. Patient-reported symptoms and quality of life are assessed up to 12 weeks after disease progression.
