Brief Summary

Colo-rectal cancer is still one of the leading causes of cancer death worldwide. In France, approximately 40 500 new cases are diagnosed each year. With more than 17 500 deaths in France in 2011, colo-rectal cancer is responsible for more than 12% of all cancer deaths, the overwhelming of deaths occurring in patients with metastatic disease.

Many studies highlight the fact that colo-rectal cancer has immunogenic properties and that host immune responses can influence survival. Recent data have provided a clearer understanding of the factors limiting the antitumor immune response in colo-rectal cancer. One of the most critical checkpoint pathways responsible for mediating tumor-induced immune suppression is the programmed death-1 (PD-1) and PD ligand 1 (PD-L1) pathway.

PD-1 is expressed on activated immune cells and can link to PD-L1 express on Antigen-Presenting-Cell. Usually, this pathway is involved in promoting T-cells tolerance and preventing tissue damage in settings of chronic inflammation. In pathological context, the PD-1/PD-L1 pathway contributes to immune suppression and evasion. Many human solid tumors including colo-rectal cancer express PD-L1, and this expression is associated with a worse prognosis. The interaction of PD-1 with the ligand PD-L1 inhibits T-cell proliferation, survival, and effectors functions; induces apoptosis of tumor-specific T cells; promotes the differentiation of CD4+ T cells into immunosuppressive regulatory T cells; and increases the resistance of tumor cells to cytotoxic T lymphocytes attack. Thus, the blockage of the PD-1/PD-L1 interactions represents a logical target for cancer immunotherapy and in particular colo rectal cancer immunotherapy strategy.

Preclinical studies have shown that PD-L1 blockade improves the immune response by restoring T-cell effectors functions. Recent work in two in vivo tumor models shows a strong interest in using an anti-PD-L1 in combination with standard treatment of colo-rectal cancer (FOLFOX). In these models, the survival of mice that are treated with the combination therapy reached 40% when no mice were alive with FOLFOX treatment alone. This result may be explained, in one hand by cytotoxicity of 5FU and in the other hand by the restoration of anti-tumor immune activity of anti-PD-L1. These results suggest that the combination of chemotherapy with immunotherapy would act synergistically in patients with colo-rectal cancer.

Research Hypothesis: Combination of chemotherapy (FOLFOX) with immunotherapy association (anti-PD-L1 + anti-CTLA-4) would act synergistically in patients with colo-rectal cancer.

Phase II primary objective (STEP 2): To determine the efficacy of the combination of Durvalumab (Anti-PD-L1) + Tremelimumab (Anti-CTLA-4) + FOLFOX in terms of progression free survival (PFS).

Phase II secondary Objective: To determine efficacy of the combination of Durvalumab (Anti-PD-L1) + Tremelimumab (Anti-CTLA-4) + FOLFOX in terms of response to treatment and overall survival.
