Abstract: Combined Immuno-chemotherapy consisting of gemcitabine, cisplatin and the programmed death-ligand one inhibitor durvalumab (GCD) is the new standard of care for patients with biliary tract cancers (BTC) based on positive results of the TOPAZ-1 study.We here evaluated the efficacy and safety of GCD for BTC in a German multicenter real-world patient cohort.Patients with BTC treated with GCD from 9 German centers were included. Clinicopathological baseline parameters, overall survival (OS), response rate and adverse events (AEs) were retrospectively analyzed. The prognostic impact was determined by Kaplan-Meier analyses and Cox regression models.A total of 165 patients treated with GCD between 2021 and 2024 were included in the study. Median OS and median progression-free survival were 14 months (95% CI 10.3-17.7) and 8 months (95% CI 6.8-9.2), respectively. The best overall response rate was 28.5% and disease control rate was 65.5%. While extrahepatic and intrahepatic BTC showed similar outcomes, mOS was significantly shorter in patients with gall bladder cancer (GB-CA) with 9 months (95% CI 5.5-12.4; p = 0.02). In univariate analyses age ≥70 years, Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≥1, status post cholecystectomy, GB-CA and high baseline CRP values were significantly associated with OS. ECOG PS ≥ 1 and GB-CA remained independent prognostic factors for OS in multivariable cox regression analysis. AEs have been reported in 130 patients (78.8%), including 149 grade 3-4 AEs (25.5%). One patient died of severe infectious pneumonia. Immune-related (ir)AEs occurred in 17 patients (10.3%), including 9 grade 3-4 irAEs (2.2%), which led to treatment interruption in 4 patients.Immuno-chemotherapy in patients with BTC was feasible, effective and safe in a real-life scenario. Our results were comparable to the phase 3 clinical trial results (TOPAZ-1). Reduced efficacy was noted in patients with GB-CA and/or a reduced performance status that warrants further investigation.
