The present invention concerns improved methods and compositions for neoadjuvant use of antibody-drug conjugates (ADCs) in cancer therapy, preferably ADCs comprising an anthracycline or camptothecin, more preferably SN-38 or pro-2-pyrrolinodoxorubicin (P2PDox). The ADC is administered as a neoadjuvant, prior to treatment with a standard anti-cancer therapy such as surgery, radiation therapy, chemotherapy, or immunotherapy. Neoadjuvant use of the ADC substantially improves the efficacy of standard anti-cancer therapy and may debulk a primary tumor or eliminate micrometasteses. In most preferred embodiments, neoadjuvant ADC in combination with a standard anti-cancer therapy is successful in treating cancers that are resistant to standard treatments, such as triple-negative breast cancer (TNBC).
本发明涉及改进的方法和组合物,用于抗体药物联合物(ADC)在癌症治疗中的新辅助使用,优选包含蒽环类或喜树碱的ADC,更优选是SN-38或pro-2-pyrrolinodoxorubicin(P2PDox)的ADC。ADC作为新辅助治疗在标准抗癌疗法(如手术、放疗、化疗或免疫疗法)之前给予。ADC的新辅助使用显著提高了标准抗癌疗法的疗效,并可减少原发肿瘤或消除微小转移。在最优选实施例中,新辅助ADC与标准抗癌疗法结合治疗对标准治疗有抵抗的癌症,如三阴性乳腺癌(TNBC)具有成功的疗效。
