    摘要: The present invention relates to a method for assessing (analyzing) the risk of potential adverse effects for a human patient mediated by the administration of a CD19xCD3 bispecific antibody to said patient comprising determining the ratio of B cells to T cells of said patient, wherein a ratio of about 1:5 or lower is indicative for a risk of potential adverse effects for said patient. Accordingly, the present invention relates a method (dosage regimen) for administering a CD19x CD3 bispecific antibody to a human patient having a B :T cell ratio of about 1:5 or lower, comprising (a) administering a first dose of said antibody for a first period of time; and consecutively (b) administering a second dose of said antibody for a second period of time, wherein said second dose exceeds said first dose.In some embodiments, a third dose of said antibody is administered for a third period of time. This dosage regimen can be applied in methods for treating malignant CD19 positive lymphocytes or for ameliorating and/or preventing an adverse effect mediated by the administration of said bispecific antibody. The present invention also relates to the use of a CD19x CD3 bispecific antibody for the preparation of a pharmaceutical composition to be used in a method of the present invention. A pharmaceutical package or kit comprising a first dose and a second dose and optionally a third dose of said antibody as defined in the methods/dosage regimen of the present invention is disclosed as well.

    摘要: The present invention provides means and methods for treating diffuse large B cell lymphoma (DLBCL). Specifically, a bispecific CD19 x CD3 antibody which engages T cells via its CD3 binding portion and concomitantly binds to CD19 on the surface of, in particular, lymphoma cells via its CD19 binding portion (i.e. a bispecific T cell engager, "BiTE") is administered for use in the treatment of tumorous mass of lymophoreticular tissue and/or extranodal lymphoma caused by DLBCL in a patient.
