Zastosowanie antagonisty ErbB, antagonista ErbB do zastosowania w metodzie leczenia raka i sposób identyfikacji pacjenta skłonnego do korzystnej odpowiedzi na antagonistę ErbB przy leczeniu raka
The invention provides a method for more effective treatment of patients susceptible to or diagnosed with tumors overexpressing ErbB, as determined by a gene amplification assay, with an ErbB antagonist. Such method comprises administering a cancer-treating dose of the ErbB antagonist, preferably in addition to chemotherapeutic agents, to a subject in whose tumor cells ErbB has been found to be amplified e.g., by fluorescent in situ hybridization. ErbB antagonists described include an anti-HER2 antibody. Pharmaceutical packaging for providing the components for such treatment is also provided.
