RecruitingPhase 3Drug trialPersonalized Medicine for Advanced Biliary Cancer PatientsThe object of this trial is to evaluate whether the introduction of a targeted therapy after 4 cycles of the current standard-of-care treatment for advanced biliary cancer is superior to continuing with the standard treatment. The trial is composed of two phases: (i) An initial screening phase to identify a suitable patient population, during which a molecular profile of the patient's tumour will be obtained, and (ii) a randomised comparative trial in which patients with disease control after 4 cycles of standard treatment, and whose tumour harbours a targetable molecular alteration, will be randomised (2:1) to receive either a matched targeted therapy or to continue with the standard treatment.
