    • The present invention concerns combinations of two or more agents for inducing an immune response to cancer or infectious disease. Agents may include leukocyte redirecting complexes, antibody-drug conjugates, interferons (preferably interferon-a), and/or checkpoint inhibitor antibodies. The leukocyte redirecting complexes have at least one binding site for a leukocyte antigen and at least one binding site for an antigen on a diseased cell or pathogen. Preferably, the complex is a DNL™ complex. More preferably, the complex comprises a bispecific antibody (bsAb). Most preferably, the bsAb is an anti-CD3 x anti-CD 19 bispecific antibody, although antibodies against other leukocyte antigens and/or disease-associated antigens may be used. The complex is capable of targeting effector T cells, NK cells, monocytes or neutrophils to induce leukocyte-mediated cytotoxicity of cells associated with cancer or infectious disease. The cytotoxic immune response is enhanced by co- administration of interferon, checkpoint inhibitor antibody and/or ADC.
    • 本发明涉及用于诱导对癌症或感染性疾病的免疫应答的两种或更多种试剂的组合。 试剂可以包括白细胞重定向复合物,抗体 - 药物偶联物,干扰素(优选干扰素-α)和/或检查点抑制剂抗体。 白细胞重定向复合物具有白细胞抗原的至少一个结合位点和病变细胞或病原体上的抗原的至少一个结合位点。 优选地,复合物是DNL TM复合物。 更优选地,复合物包含双特异性抗体(bsAb)。 最优选地,bsAb是抗CD3×抗-CD19双特异性抗体,尽管可以使用针对其它白细胞抗原和/或疾病相关抗原的抗体。 复合物能够靶向效应T细胞,NK细胞,单核细胞或嗜中性粒细胞,以诱导与癌症或感染性疾病相关的细胞的白细胞介导的细胞毒性。 通过共同施用干扰素,检查点抑制剂抗体和/或ADC来增强细胞毒性免疫应答。
