In-Situ Therapeutic Cancer Vaccine for Metastatic Cancer Combining AlloStim With Tumor Cryoablation

This is a Phase I/II study to investigate the feasibility of creating a personalized therapeutic cancer vaccine within the body. A vaccine contains a source of tumor antigen and an adjuvant. In this study, tumor antigen is generated by freezing a tumor by a minimally invasive percutaneous (through the skin) cryoablation procedure. The study drug, AlloStim, is injected into the ablated tumor to promote development of an anti-tumor immune response.
