Synergism of Immunomodulation and Tumor Ablation
Summary
This is a single-arm, open-label, multi-center early phase II study. This proof of concept study will investigate whether the combined use of local tumor ablation/radiation plus immunomodulating drugs may induce a significant immune response in patient with incurable liver metastases from colorectal cancer (CRC) (+/- limited extrahepatic disease) being stable or in partial remission after completion of 4-6 months first line systemic therapy. The primary objective of the study is to show an overall response rate of lesions not treated by ablation/radiotherapy including the extrahepatic lesions (according to iRECIST criteria) higher than 10%. With the continuation of first line systemic treatment, no further responses are expected. Secondary objectives are: * To establish the feasibility and safety of the combined treatment modalities; * To study the impact of the local technique (RFA/Radiotherapy) on the results; * To investigate biomarkers to predict response to the combined treatment
