Combination of anti-CTLA4 antibody with diverse therapeutic regimens for the synergistic treatment of proliferative diseases
Compositions and methods are disclosed which are useful of the treatment and prevention of proliferative disorders. Such Compositions comprise inter alia an anti-CTLA-4 agent, e.g. ipilimumab or tremelimumab in combination with other chemotherapeutic agents such as dasatinib, imatinib, paclitaxel, gemcitabine, cisplatin or etoposide.
1. A method for the treatment of cancer, consisting of the administration to a mammal in need thereof a synergistic, therapeutically effective amount of an anti-CTLA-4 antibody, in addition to one or more diluents, vehicles, excipients, and/or inactive ingredients, at a dose ranging from about 3 mg/kg to about 10 mg/kg; with the chemotherapeutic agent 4′-Demethylepipodophyllotoxin 9-[4,6-O-(R)-ethylidene-β-D-glucopyranoside], 4′-(dihydrogen phosphate), or a pharmaceutically acceptable salt, solvate, or hydrate thereof, at a dose of 100 mg/kg; wherein said treatment is sufficient to synergistically reduce tumor burden, produce tumor regression, or reduce tumor development of said cancer.
