Interest of iRECIST Evaluation for DCR for Evaluation of Patients With Deficient MMR and /or MSI Metastatic Colorectal Cancer Treated With Nivolumab and Ipilimumab

Brief description of study

This is a non-randomized study, open label phase II study. The purpose of this study is to evaluate disease control rate (DCR) by RECIST and iRECIST at 12 weeks.

Evaluation of RECIST and iRECIST will be done in each center in order to choose the optimal therapy (Assessment by Investigators).

A centralized evaluation of RECIST and iRECIST, will be organized in Saint-Antoine.

Detailed Study Description

Recent studies have shown sensitivity to immunotherapy treatment in patients with metastatic colorectal cancer with a dMMR tumor. The association nivolumab plus ipilimumab demonstrated encouraging results with durable responses in these patients.

The criteria for assessing responses for solid tumors are currently based on RECIST 1.1, which are well correlated with the clinical response to chemotherapy. However, in patients treated with immunotherapy, such criteria are less accurate, as already demonstrated in the treatment of metastatic melanoma, but not yet in other malignant tumors.

Therefore, we hope with this study, to identify more accurate imaging criteria that could help oncologists to make optimal decisions for treatment.
