Patent

CA 2718233

The present invention discloses and claims compositions, methods of treatment, and kits which cause an increase in time of survival in cancer patients, wherein the cancer either: (i) overexpresses thioredoxin or glutaredoxin and/or (ii) exhibits evidence of thioredoxin- or glutaredoxin-mediated resistance to one or more chemotherapeutic interventions. The present invention also discloses and claims methods and kits for the administration of said compositions to properly treat cancer patients. Additionally, the present invention discloses and claims methods and kits for quantitatively determining the level of expression of thioredoxin or glutaredoxin in the cancer cells of a cancer patient, methods of using those determined levels in the initial diagnosis and/or planning of subsequent treatment methodologies for said cancer patient, as well as ascertaining the potential growth 'aggressiveness' of the particular cancer and treatment responsiveness of the particular type of cancer. Further, the present invention discloses and claims novel pharmaceutical compositions, methods, and kits used for the treatment of patients with medical conditions and disease where there is the overexpression of thioredoxin and/or glutaredoxin, and wherein this overexpression is associated with deleterious physiological effects in the patients.

La présente invention concerne des compositions, des procédés de traitement, et des trousses qui entraînent une augmentation du temps de survie chez des patients atteints du cancer, ce cancer entraînant soit (i) la surexpression de thiorédoxine ou de glutarédoxine et/ou (ii) lévidence de résistance médiée par la thiorédoxine ou la glutarédoxine à une ou des interventions chimiothérapeutiques. La présente invention concerne également des procédés et des trousses pour ladministration desdites compositions pour le traitement approprié de patients atteints de cancer. La présente invention concerne en outre des procédés et des trousses permettant la détermination quantitative du niveau dexpression de la thiorédoxine ou de la glutarédoxine dans des cellules cancéreuses dun patient atteint de cancer, des procédés dutilisation de ces niveaux déterminés dans le diagnostic initial et/ou la planification de méthodologies de traitement ultérieures pour ledit patient atteint de cancer, ainsi que la détermination de lagressivité de croissance potentielle du cancer particulier et la sensibilité au traitement du type de cancer particulier. La présente invention concerne enfin de nouvelles compositions pharmaceutiques, de nouveaux procédés, et de nouvelles trousses pour le traitement de patients souffrant de conditions médicales et maladie où il y a une surexpression de thiorédoxine et/ou de glutarédoxine, et où cette surexpression est associée à des effets physiologiques délétères chez les patients.
