The present invention relates to the field of immunotherapeutics. It provides a method for characterisation and quality control, in particular for determining the potency of an immunoglobulin composition comprising immunoglobulins derived from a plurality of human donors, the method comprising contacting the immunoglobulin composition with pneumolysin, adding erythrocytes to the immunoglobulin composition and determining lysis of the erythrocytes. The invention also provides a corresponding use of pneumolysin, as well as a kit and composition useful in said method. The method can be used for quality control of immunoglobulin concentrate, e.g., of an IgM-containing immunoglobulin composition comprising IgM, IgA and IgG antibodies, and in a method of preparing an immunoglobulin composition. The immunoglobulin compositions obtainable from said method may be used, e.g., in the treatment of pneumonia, e.g., severe community-acquired pneumonia, which may be caused, e.g., by

Method and kit for testing potency of immunoglobulin compositions

Disclosed is a method and composition for treating a disease associated with target cells expressing CD138 in a multiple dose regimen. An immunoconjugate comprising an engineered targeting antibody targeting CD138 expressing cells and an effector molecule is administered in a multiple dose regimen. The multiple dose regimen comprises at least two doses and the aggregate dose administered within an active treatment cycle is an aggregate maximum tolerable dose (AMTD) or a fraction of the AMTD. The AMTD and/or said fraction exceeds the dose resulting in dose limiting toxicity (DLT) 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.

Uses of immunoconjugates targeting CD138

Provided is a humanized or chimeric antibody or fragment thereof capable of binding to interleukin-10 (IL-10), wherein said antibody or fragment thereof is capable of being administered to a subject in the absence of an intolerable increase in the level of pro-inflammatory cytokines. Further provided are methods of treatment involving the use of the antibody or fragment thereof.

Humanized anti-IL-10 antibodies for the treatment of systemic lupus erythematosus (SLE)

Provided is a humanized or chimeric antibody or fragment thereof capable of binding to interleukin-10 (Th-10), wherein said antibody or fragment thereof is capable of being administered to a subject in the absence of an intolerable increase in the level of pro-inflammatory cytokines. Further provided are methods of treatment involving the use of the antibody or fragment thereof.
