Durvalumab Plus Gemcitabine and Cisplatin in Patients with Advanced Biliary Tract Cancer: An Exploratory Analysis of Real-World Data
TARGETED ONCOLOGY(2024)
摘要
BackgroundThe combination of gemcitabine and cisplatin (gem/cis) with the anti-PD-L1-antibody durvalumab was recently approved as first line therapy for biliary tract cancer (BTC) based on the results of the TOPAZ-1 trial.ObjectiveWe aim to analyse the feasibility and efficacy of the triple combination therapy in patients with BTC in a real-world setting and in correspondence with the genetic alterations of the cancer.MethodsIn this single-centre retrospective analysis, all patients with BTC and treated with durvalumab plus gem/cis from April 2022 to September 2023 were included. Survival and treatment response were investigated, within the context of the inclusion and exclusion criteria of TOPAZ-1 and in correspondence with genetic alterations of the cancer.ResultsIn total, 35 patients, of which 51% met the inclusion criteria of the TOPAZ-1 trial, were analysed. Patients treated within TOPAZ-1 criteria did not have a significantly different median overall survival and progression free survival than the rest of the patients (10.3 versus 9.7 months and 5.3 versus 5 months, respectively). The disease control rate of patients within the TOPAZ-1 criteria was 61.1%, in comparison to 58.8% in the rest of patients. A total of 51 grade 3 and 4 adverse events were observed without significant differences in the subgroups. No specific correlating patterns of genetic alterations with survival and response were observed.ConclusionsThe treatment of advanced patients with BTC with durvalumab and gem/cis, even beyond the inclusion criteria of the TOPAZ-1 trial, shows promising safety.
