Experimental Therapeutic Cancer Vaccine Created In-situ in Patients With Stage II-Stage IV Cancer

This is a Phase I/II clinical study to investigate the optimal protocol and indication for creating a personalized anti-tumor vaccine within the body of patients with cancer. The aim of the study is to evaluate the safety of administration and anti-tumor effect of a vaccine protocol that has three separate steps. Cancer patients generally present with an immune response to cancer biased to a Th2 response, while a Th1 response is considered necessary for mediating anti-tumor immunity. The first step of the study consists of multiple intradermal priming doses of AlloStimTM. The aim of this step is to create Th1 immunity to the alloantigens in AlloStimTM, thus increasing the number of Th1 cells in circulation. The second step of the protocol involves the cryoablation of a selected tumor lesion followed by an intratumoral AlloStimTM injection. The aim of this step is to generate tumor-specific CTL killer cells in the circulation. The final step is an intravenous infusion of AlloStimTM. The aim of this step is to activate circulating Th1 cells, killer cells, and natural killer cells. The further aim of this step is to create an inflammatory environment that can break-down the ability of the tumor to avoid an anti-tumor immune response. In patients with partial responses and recurrence of disease, additional intravenous "booster" infusions are utilized to reactivate the circulating immune cells.
