Local Immunomodulation After Radiofrequency of Unresectable Colorectal Liver Metastases

Summary

The main objective of this trial is to determine feasibility and tolerance of the human body to RFA associated with local immunomodulation carried out using a thermoreversible hydrogel combined with 2 immunomodulators, GMCSF and Mifamurtide. The main endpoint of the study is the feasibility, the frequency and the nature of per and post-operative adverse events of the in situ injection of an immunomodulatory hydrogel after radiofrequency of unresectable colorectal liver metastases. The secondary objective is one-year progression free survival rate.
