The present invention provides a method for treating NSCL, pancreatic, colon or breast cancer tumors or tumor metastases in a patient, comprising administering to the patient simultaneously or sequentially a therapeutically effective amount of a combination of an EGFR kinase inhibitor and an agent that sensitizes tumor cells to the effects of EGFR kinase inhibitors, wherein the agent is an mTOR inhibitor, with or without additional agents or treatments, such as other anti-cancer drugs or radiation therapy. The present invention also provides a method for treating tumors or tumor metastases in a patient, comprising administering to said patient simultaneously or sequentially a therapeutically effective amount of a combination of an EGFR kinase inhibitor and an agent that sensitizes tumor cells to the effects of EGFR kinase inhibitors, wherein said agent is an mTOR inhibitor that binds to and directly inhibits both mTORC1 and mTORC2 kinases. The present invention also provides a pharmaceutical composition comprising an EGFR kinase inhibitor and an mTOR inhibitor that binds to and directly inhibits both mTORC1 and mTORC2 kinases, in a pharmaceutically acceptable carrier. A preferred example of an EGFR kinase inhibitor that can be used in practicing the methods of this invention is the compound erlotinib HCl (also known as TARCEVA®).
本发明提供了一种治疗患有非小细胞肺癌、胰腺癌、结肠癌或乳腺癌肿瘤或转移瘤的患者的方法,包括同时或顺序给患者施用治疗有效量的EGFR激酶抑制剂和一种使肿瘤细胞对EGFR激酶抑制剂产生敏感作用的药物,其中该药物为mTOR抑制剂,可以加入其他抗癌药物或放疗等额外的药物或治疗方法。本发明还提供了一种治疗患者肿瘤或转移瘤的方法,包括同时或顺序给患者施用治疗有效量的EGFR激酶抑制剂和一种使肿瘤细胞对EGFR激酶抑制剂产生敏感作用的药物,其中该药物为一种mTOR抑制剂,可结合并直接抑制mTORC1和mTORC2激酶。本发明还提供了一种制药组合物,包括一种EGFR激酶抑制剂和一种可结合并直接抑制mTORC1和mTORC2激酶的mTOR抑制剂,以及药学上可接受的载体。本发明中可用于实施方法的EGFR激酶抑制剂的首选示例是化合物依洛替尼盐酸盐(也称为TARCEVA®)。
