    摘要: The present invention provides a bispecific antibody construct comprising a first binding domain specifically binding to a target such as CD33 and a second binding domain specifically binding to an effector such as CD3 for use in a method for the treatment of myeloid leukemia, wherein the construct is administered in one or more treatment cycles of more than 14 days applying a step dosing comprising at least two steps, a treatment cycle optionally followed by a period without administration of the construct. Moreover, the invention provides a method for the treatment of myeloid leukemia comprising the administration of a therapeutically efficient amount of such bispecific antibody construct and the use of such bispecific antibody construct for the preparation of a pharmaceutical composition for the treatment of myeloid leukemia.
