Embodiment Construction

[0009] 1. Definition

[0010] As used herein, the term "administering" or "administering" means administering a pharmaceutical composition, such as an angiogenesis inhibitor, to a patient in need of such treatment or medical intervention by any suitable means known in the art. Non-limiting routes of administration include oral, intravenous, intraperitoneal, subcutaneous, intramuscular, topical, intradermal, intranasal or intrabronchial administration (eg, by inhalation). Particularly preferred in the context of the present invention is parenteral administration, eg intravenous administration.

[0011] The terms "anti-angiogenic agent" or "angiogenesis inhibitor" refer to small molecular weight substances, polynucleotides, which either directly or indirectly inhibit angiogenesis, vasculogenesis or unwanted vascular permeability, Polypeptides, isolated proteins, recombinant proteins, antibodies, or conjugates or fusion proteins thereof. It is understood that anti-angiogenic ag...

Abstract

The present invention provides methods for improving the treatment effect of a chemotherapy regimen of a patient suffering from HER2 positive breast cancer, in particular locally recurrent or metastatic HER2 positive breast cancer, by adding bevacizumab (Avastin TM ) to a chemotherapy regimen by determining the expression level, in particular the blood plasma expression level, of VEGFA and / or VEGFR2 relative to control levels of patients diagnosed with HER2 positive breast cancer, in particular locally recurrent or metastatic HER2 positive breast cancer. The present invention also provides for methods for assessing the sensitivity or responsiveness of a patient to bevacizumab (Avastin TM ) in combination with a chemotherapy regimen, by determining the expression level, in particular the blood plasma expression level, of VEGFA and / or VEGFR2 relative to control levels in patients diagnosed with HER2 positive breast cancer, in particular locally recurrent or metastatic HER2 positive breast cancer.

Description

field of invention [0001] The present invention is directed to methods for identifying which patients diagnosed with HER2-positive breast cancer would most benefit from treatment with an anti-cancer therapy comprising an anti-VEGF antibody. Background of the invention [0002] Angiogenesis contributes to benign and malignant diseases such as cancer formation and, especially in cancer, is required for primary tumor growth, invasion and metastasis. In order to grow, tumors must undergo an angiogenic switch. Vascular endothelial growth factor (VEGF) is required to induce this angiogenic switch. VEGF and genes in the VEGF pathway are considered important mediators of cancer progression. The VEGF gene family includes the VEGF gene (also known as VEGFA), homologues of VEGF including placental growth factor (PlGF), VEGFB, VEGFC, VEGFD, VEGF receptors including VEGFR-1 and VEGFR-2 (also known as FLT1 and FLK1 / KDR), VEGF inducers, including hypoxia inducible factors HIF1α, HIF2α, ...
