(EN) INHIBITION OF TUMOR GROWTH BY BLOCKADE OF THE PROTEIN C SYSTEM
(FR) INHIBITION DE LA CROISSANCE TUMORALE PAR BLOCAGE DU SYSTEME DE LA PROTEINE C
Abstract: front page image
(EN) Compositions, and methods of use thereof, for the inhibition of tumor growth and killing of tumors having extensive microcirculation 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 and granulocyte-macrophage colony stimulating factor. Examples are provided demonstrating the administraion of the protein C blocking compound, alone or in combination with TNF, to dogs having canine venereal tumors, a fibrosarcoma, and an adenocarcinoma, to pigs with melanoma, and a primate with a malignant lymphoma, followed by significant tumor reduction.
(FR) Des compositions et leurs procédés d'utilisation permettent d'inhiber la croissance tumorale et de détruire des tumeurs a microcirculation étendue. L'agent actif est un composé qui bloque le système de protéine C, de préférence un anticorps de l'anti-protéine C, un anticorps de l'anti-protéine S et une protéine de liaison de C4b. Dans le mode préférentiel de réalisation, le composé de blocage de la protéine C est associé à une cytokine telle que le facteur de nécrose de tumeurs (TNF), l'interféron gamma, l'interleucine-1, l'interleucine-2 et le facteur de stimulation des colonies de granulocytes-macrophages. On décrit des exemples d'administration du composé de blocage de la protéine C, que ce soit isolément ou en association avec TNF, à des chiens ayant des tumeurs vénériennes canines, un fibrosarcome, et un adénocarcinome, à des cochons ayant des mélanomes, et à un primate avec un lymphome malin, l'administration du composé ayant été suivie d'une réduction significative des tumeurs.
