In the present TACTIC clinical trial, the investigators propose to determine the clinical interest and immunological efficacy of a treatment combining MP0317 the FAP (Fibroblast Activation Protein)-dependent CD40 agonist, with anti-PD-L1(Programmed Death-Ligand 1) therapy (durvalumab) and gemcitabine-cisplatin-based chemotherapy in unresectable cholangiocarcinoma.
The main objective is to assess the 12-month progression free survival (PFS) rate in the experimental arm. The trial proposed is a non-comparative proof of concept randomized two-stage phase II. The control arm will serve to verify the good calibration of the null hypothesis made in the experimental arm and to provide "true" controls for translational investigations. A semi-continuous monitoring of toxicity is planned in the experimental arm during the first stage of the study to warrant the tolerability of the experimental treatment and then to guarantee the security of the patients.
75 patients (50 in the experimental arm) will be included. The investigators will also decipher, as a translational objective, the molecular and immunological parameters determining the clinical outcomes.
