    • The present invention relates to anti-matriptase antibodies and immunoconjugates of anti- matriptase antibodies with cytotoxic agents and the use thereof for killing or inhibiting the growth of matriptase-expressing cancer cells, such as those of multiple myeloma and breast cancers. In particular, immunoconjugates comprising an anti-matriptase monoclonal antibody and anticancer agents such as auristatin, including monomethyl auristatin E (MMAE) and monomethyl auristatin F (MMAF) are introduced, which have potent antitumor activity in vivo. Moreover, importantly; there was no weight loss or other evidence of toxicity in the animals, indicating that no significant free drug was released into the circulation from the conjugate. The present invention also provides compositions comprising these new immunoconjugates and use of them for treatment of malignancies comprising cells that express matriptase. In addition, administration of an anti-matriptase antibody or immunoconjugates of an anti-matriptase antibody and a cytotoxic agent in combination with administration of an immunomodulatory agent, such as thalidomide or an analog thereof, provides a more effective treatment of these cancers.
    • 本发明涉及抗matriptase抗体和抗matriptase抗体与细胞毒性剂的免疫偶联物,及其用于杀死或抑制表达matriptase的癌细胞例如多发性骨髓瘤细胞的生长的用途 和乳腺癌。 具体而言,引入了包含抗matriptase单克隆抗体和抗癌剂如奥里斯他汀的免疫缀合物,包括单甲基奥里斯他汀E(MMAE)和单甲基奥里斯他汀F(MMAF),其在体内具有有效的抗肿瘤活性。 而且,重要的是; 在动物中没有体重减轻或其他毒性证据,表明没有显着的游离药物从缀合物释放到循环中。 本发明还提供了包含这些新型免疫缀合物的组合物以及它们用于治疗包含表达matriptase的细胞的恶性肿瘤的用途。 另外,抗matriptase抗体或抗matriptase抗体和细胞毒性剂的免疫偶联物与施用免疫调节剂(例如沙利度胺或其类似物)组合提供了对这些癌症的更有效的治疗。 p>
