The instant disclosure provides antibody fragments (e.g., Fab and F(ab).sub.2) having reduced or no reactivity towards pre-existing anti-hinge antibodies (AHA) and compositions comprising such antibody fragments, as well as methods of making and using such antibody fragments and compositions.

The invention relates to cancer therapeutics, in particular, the system of making cancer cells more susceptible to effector cells by introduction of cellular therapy targets into the cancer cells.

This invention relates generally to the inhibition of cytomegalovirus (CMV) reactivation in immunosuppressed subjects, including subjects receiving hematopoietic or solid organ transplants. The present invention is particularly relevant for the treatment of CMV reactivation or infection in subjects with graft-versus-hosts disease (GVHD) or under immunosuppressive therapy.

The present invention relates to the diagnosis and treatment of B-cell disorders such as multiple myeloma (MM). In particular, the present invention relates to the treatment of B-cell disorders using ligands which bind to free lambda light chains expressed on the surface of lymphoid cancer cells.

This invention provides, and in certain specific but non-limiting aspects relates to: assays that can be used to predict whether a given ISV will be subject to protein interference as described herein and/or give rise to an (aspecific) signal in such an assay (such as for example in an ADA immunoassay). Such predictive assays could for example be used to test whether a given ISV could have a tendency to give rise to such protein interference and/or such a signal; to select ISV's that are not or less prone to such protein interference or to giving such a signal; as an assay or test that can be used to test whether certain modification(s) to an ISV will (fully or partially) reduce its tendency to give rise to such interference or such a signal; and/or as an assay or test that can be used to guide modification or improvement of an ISV so as to reduce its tendency to give rise to such protein interference or signal; methods for modifying and/or improving ISV's to as to remove or reduce their tendency to give rise to such protein interference or such a signal; modifications that can be introduced into an ISV that remove or reduce its tendency to give rise to such protein interference or such a signal; ISV's that have been specifically selected (for example, using the assay(s) described herein) to have no or low(er)/reduced tendency to give rise to such protein interference or such a signal; modified and/or improved ISV's that have no or a low(er)/reduced tendency to give rise to such protein interference or such a signal.

The present invention pertains to the field of protein engineering, and provides means for obtaining stable molecules that specifically bind to a target selected amongst a large variety of ligands families. In particular, the present invention provides methods for obtaining a molecule specifically binding to a target of interest, through a combinatorial mutation/selection approach with an OB-fold protein as a starting molecule. In particular, the target of interest can be of a different chemical nature form that of the native target of the OB-fold protein used as the starting molecule.

The instant disclosure provides antibody fragments (e.g., Fab and F(ab).sub.2) having reduced or no reactivity towards pre-existing anti-hinge antibodies (AHA) and compositions comprising such antibody fragments, as well as methods of making and using such antibody fragments and compositions.

The present disclosure relates to antibody-drug conjugates comprising ALK5 inhibitors and their uses.

The invention provides modifications within human or humanized single domain antibody fragments (sdAbs) that prevent recognition by pre-existing antibodies, to isolated polypeptides that include these modifications, and to methods and uses thereof.

Provided is an antibody that has a high binding activity to membrane-bound IgM on the surface of B cells and exhibits a growth inhibition effect on the B cells, even in the presence of soluble IgM in blood.

A bispecific antibody, which binds to IgM and a B cell surface antigen.
