Abstract:
Compositions, and methods of use thereof, for the inhibition of tumor growth and killing of solid tumors wherein the active agent is a compound blocking the Protein C system, preferably anti-Protein C antibody, anti-Protein S antibody, and C4b binding protein. In the most preferred embodiment, the Protein C blocking compound is provided in combination with a cytokine such as tumor necrosis factor (TNF), gamma interferon, interleukin-1, interleukin-2,p or granulocyte-macrophage colony stimulating factor, or a compound eliciting cytokine production such as endotoxin. Examples are provided demonstrating the administration of the Protein C blocking compound, alone or in combination with TNF or endotoxin, to animals having canine veneral tumors, a fibrosarcoma, and an adenocarcinoma, followed by significant tumor reduction.
