In-Situ Cancer Vaccine: Phase IIA, Open-Label Study to Assess the Safety of AlloStim® Immunotherapy Alone and in Combination With Cryoablation as Third Line Therapy for Metastatic Colorectal Cancer
In Brief
A Phase 2 clinical trial evaluating AlloStim and Cryoablation for Colorectal Cancer Metastatic. Completed, enrolled 13 participants across 1 site.
Detailed Summary
This is a single center, open label dose frequency escalation study of CryoVax®. personalized anti-tumor vaccine protocol combining the cryoablation of a selected metastatic lesion with intra-lesional immunotherapy with AlloStim®. The in-situ (in the body) cancer vaccine step combines killing a single metastatic tumor lesion by use of cryoablation in order to cause the release of tumor-specific markers to the immune system and then injecting bioengineered allogeneic immune cells (AlloStim®) into the lesion as an adjuvant in order to modulate the immune response and educate the immune system to kill other tumor cells where ever they reside in the body.

Timeline
Interventions
AlloStim is an activated living CD4+ Th1 memory cell derived from the blood of normal blood donors and intentionally mismatched to the recipient. AlloStim is bioengineered to express high levels of Type 1 inflammatory cytokines (such as interferon-gamma, TNF-alpha, GM-CSF) and immunomodulatory molecules such as CD40L. AlloStim has CD3/CD28-coated microbeads attached to assure activation upon infusion.
Percutaneous partial cryoablation of a single metastatic tumor lesion in the liver. The procedure is conducted under CT or ultrasound image-guidance
