What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 75 participants in total. It began in 2025-12-22 with a primary completion date of 2028-11.

Brief Summary

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.

Post-menopausal is defined as aged more than 50 years and amenorrhoeic for at least 12 months following cessation of all exogenous hormonal treatments. 2. Women under the age of 50 years would be considered postmenopausal if they have been amenorrhoeic for 12 months or more following cessation of exogenous hormonal treatments and with luteinizing hormone and follicle stimulating hormone levels in the post-menopausal range for the institution. 3.
