Disclosed are compositions and methods for enhancing a cytocidal immune response directed against a preselected cell-type in a mammal. The methods and compositions rely on a combination of an antibody- cytokine immunoconjugate and an angiogenesis inhibitor. Once administered to the mammal, the immunoconjugate induces an immune response against the preselected cell-type, for example, a cancer cell which, as a result of the synergy with the angiogenesis inhibitor, is greater than the immune response induced by the immunoconjugate alone. The methods and compositions are particularly useful at killing solid tumors or virally-infected cells in a mammal.

La présente invention concerne des compositions et des procédés permettant de renforcer une réponse immunitaire cytocide dirigée contre un type cellulaire choisi de mammifère. Le procédé ainsi que les compositions impliquent une combinaison associant un immunoconjugué de cytokine d'anticorps et un inhibiteur de l'angiogenèse. Une fois qu'il est administré au mammifère, l'immunoconjugué induit une réponse immunitaire contre le type cellulaire choisi, par exemple une cellule cancéreuse qui, grâce à la synergie avec l'inhibiteur de l'angiogenèse, est supérieure à la réponse immunitaire induite par l'immunoconjugué seul. Ces procédés et compositions conviennent particulièrement pour tuer les tumeurs solides ou les cellules à infections virales chez un mammifère.
