    • The present invention relates to targeted delivery systems for delivering therapeutic agents to tumor. The invention further relates to methods of delivering a therapeutic agent to a tumor for the prevention and treatment of cancer by killing tumor cells and tumor associated endothelial cells. In particular, the present invention provides a tumor-targeted drug delivery system comprising a NGR-containing molecule linked to a delivery vehicle encapsulating a therapeutic agent, preferably a drug, such as a cytotoxic agent or a chemotherapeutic agent. Specifically, the delivery systems of the present invention are capable of delivering an increased amount of therapeutic agent to a tumor as compared to other delivery systems. In particular, the delivery systems of the present invention are capable of accumulating a higher amount of therapeutic agent in a tumor, or in the vicinity of a tumor cell or tumor-supporting cell, resulting in exposure of the tumor cell and tumor associated endothelial cell to therapeutic levels of the agent for a longer period of time as compared to other delivery systems. The present invention also describes pharmaceutical compositions comprising the delivery systems of the present invention. The present invention further relates to a tumor treatment comprising an increased amount of therapeutic agent delivered by the system of the present invention as compared to other delivery systems. The delivery systems and pharmaceutical compositions can be administered to a subject, preferably a human, alone or in combination, sequentially or simultaneously, with other prophylactic or therapeutic agents and/or anti-cancer treatments.
    • 本发明涉及用于将治疗剂递送至肿瘤的靶向递送系统。 本发明还涉及通过杀死肿瘤细胞和肿瘤相关内皮细胞将治疗剂递送至肿瘤以预防和治疗癌症的方法。 特别地,本发明提供了一种肿瘤靶向药物递送系统,其包含与包封治疗剂,优选药物例如细胞毒剂或化学治疗剂的递送载体连接的含NGR分子。 具体地说,与其他递送系统相比,本发明的递送系统能够将更多量的治疗剂递送到肿瘤。 特别地,本发明的递送系统能够在肿瘤或肿瘤细胞或肿瘤支持细胞附近积聚更多量的治疗剂,导致肿瘤细胞和肿瘤相关的内皮细胞的暴露 与其他递送系统相比,治疗剂量更长的时间。 本发明还描述了包含本发明的递送系统的药物组合物。 本发明还涉及一种肿瘤治疗,其包括与其它递送系统相比,本发明的系统递送的治疗剂的量增加。 递送系统和药物组合物可以与其他预防或治疗剂和/或抗癌治疗单独或组合地依次或同时地施用于受试者,优选人。
