The investigators hypothesize that Ca-EP targeting the primary CRC tumor combined with IRE targeting a metastasis will be a promising, safe two target approach to ensure sufficient immune response both locally and systemic to potentiate the efficacy of immunotherapy in patients with pMMR metastatic CRC.
The trial is designed as an investigator initiated prospective phase 2 study in patients with metastatic pMMR colorectal cancer (CRC) to determine the safety and efficacy of calcium electroporation (CaEP) performed concurrently with irreversible electroporation (IRE) followed by a PD-1 inhibitor (pembrolizumab).
