Current Research

Immunotherapy Against Cancers in the Liver

My work focuses on immune stimulation to fight primary and metastatic cancers in the liver. There are 2 main
protocols. The first ( Protocol ID NCT00553683) uses autologous prime-boost anti-tumor vaccination
in patients with hepatomas or metastatic cancers (pancreas, neuroendocrine, gastric, colon, breast) to the cancer in the
liver. This is a phase I/IIa clinical trial using 1) low dose cyclophosphamide to reduce tumor driven immune tolerance,
2) low dose radiation to the tumor, to increase expression of tumor antigens, 3) injection of an immune stimulant, TLR
III agonist Poly IC:LC, into and around the tumor to activate the body’s immune defenses, and 4) tumor ablation to
reduce production of tumor promoting and immunosuppressive factors. This is referred to as “Priming”. Patients are
then subject to systemic administration of POLY ICLC to “Boost” the anti-tumor immune response.

The second ( Protocol ID NCT01387555) uses an oncolytic poxvirus, or vaccinia virus (JX-594) that are
highly selective to attack cancers and have minimal side effects, limited to flu-like symptoms. The (JX-594 strain
backbone of has been used safely in millions of people as part of a worldwide vaccination program. Features include 1)
rapid and motile spread in tumors (increased potency), 2) intravenous stability and delivery to solid tumors, 3)
therapeutic transgene-arming capacity, and 4) antidotes are available (to maximize safety). JX-594 is an engineered
oncolytic virus designed to selectively destroy cancer cells through three diverse mechanisms of action: 1) the lysis of
cancer cells through viral replication, 2) the reduction of the blood supply to tumors through vascular targeting and
destruction, and 3) the stimulation of the body's immune response against cancer cells. JX-594 exploits a specific
genetic feature in cancer cells to become activated and lyse the cells, including the EGFR-ras signaling pathway, the cell
cycle activation and the loss of cellular interferon defenses. JX-594 is a Wyeth vaccinia virus with a disruption of the viral
thymidine kinase (tk) gene and expression of the immunostimulatory cytokine, GM-CSF (granulocyte macrophage
colony-stimulating factor).
