  • Publication number: 20050119288
    Abstract: The invention is directed to methods for the a method for treating overexpression of the erbB2 in a mammal in need of treatment by administering to the mammal a therapeutically effective amount of a first inhibitor of an erbB2 receptor and then, after an interval of less than 24 hours, administering to the mammal from one to six therapeutically effective amounts of the same or different inhibitor of the erbB2 receptor. The invention is also directed to a slow daily infusion of the erbB2 inhibitor. The overexpression of the erbB2 receptor can result in abnormal cell growth and lead to cancer. By the methods of the invention, the efficacy and safety of the inhibitors is increased. The invention is also directed to kits for facilitating the dose administration method of the invention.
