ADJUBIL: Phase II Study of Adjuvant Immunotherapy with STRIDE Regimen With/Without Capecitabine in Biliary Tract Cancers

Biliary tract cancer is a highly heterogeneous group of gastrointestinal cancers, and the only curative treatment is surgery, which is only applicable at early stages of the malignancy. ADJUBIL, a phase II trial (NCT05239169), aims to evaluate immunotherapy with durvalumab and tremelimumab with or without capecitabine in adjuvant situations for biliary tract cancers. A total of 40 prospective patients will be randomly assigned following surgery, consisting of a two-arm feasibility pilot part with a pick-the-winner design with durvalumab and tremelimumab in combination with or without capecitabine.
