Provided is a method for treating a disease associated with target cells expressing CD 138 comprising: administering to a subject, in particular a human subject, in need thereof an immunoconjugate comprising at least one engineered targeting antibody targeting CD138 expressing cells, and at least one effector molecule, wherein said engineered targeting antibody is functionally attached to said effector molecule to form said immunoconjugate, wherein preferably at least a part of the engineered targeting antibody confers lgG4 isotype properties, wherein the immunoconjugate is administered in a multiple dose regimen comprising at least two doses, wherein the aggregate dose administered within an active treatment cycle is an aggregate maximum tolerable dose (AMTD) or a fraction of the AMTD and wherein said AMTD and/or said fraction exceeds the dose resulting in dose limiting toxicity (DLT) when the immunoconjugate is administered as a single dose, including as part of a multiple single dose regimen and/or exceeds the maximum tolerable dose (MTD) when the immunoconjugate is administered as a single dose, including as part of a multiple single dose regimen within said active treatment cycle.
提供了一种治疗与表达CD138的靶
细胞相关的疾病的方法,包括:向需要该方法的受试者,特别是人类受试者,给予至少包含一种工程靶向
抗体和至少一种效应分子的免疫结合物,其中所述的工程靶向
抗体与所述的效应分子在功能上连接以形成所述的免疫结合物,其中所述的工程靶向
抗体的至少一部分赋予lgG4亚型特性,其中所述的免疫结合物以多剂量方案给予,包括至少两剂,其中在活动治疗周期内给予的总剂量为最大可耐受剂量(
