The present invention relates to bispecific antibodies that specific bind to BCMA (B-Cell Maturation Antigen) and CD3 (Cluster of Differentiation 3). Method of making the bispecific antibodies and method of using the bispecific antibodies for the treatment of multiple myeloma are also provided.

The invention generally relates to methods and compositions for the prediction of therapeutic efficacy of cancer treatments and the prognosis of cancer. The invention discloses markers that are associated with favorable and unfavorable outcomes, respectively, in certain cancer treatments and are useful as prognostic markers for cancer. Methods involving these markers are disclosed for predicting cancer therapy benefit and prognosing clinical outcome for cancer patients.

The present invention provides a means capable of efficiently manufacturing a fused substance of an Fc protein and a substance of interest (for example, a peptide). Specifically, the present invention provides an azide group-containing Fc protein represented by formula (1):
N.sub.3-L.sub.a-Phe-L.sub.b-Fc  (1)
wherein N.sub.3 represents an azide group; L.sub.a represents a bond or a divalent group; Phe represents a residue of phenylalanine or a derivative thereof; L.sub.b represents a lysine residue or an arginine residue, or a peptide linker containing two or more amino acid residues having a lysine residue or an arginine residue at/on the N-terminus; and Fc represents an Fc protein; and the like.

Provided herein are conjugated immunoglobulins and methods for generating conjugated immunoglobulins using a microbial transglutaminase.

The present invention relates to therapeutic ADCs comprising SN-38 attached to an anti-Trop-2 antibody or antigen-binding antibody fragment, more particularly sacituzumab govitecan. The ADC is administered to a subject with a Trop-2 positive cancer that is resistant to or relapsed from prior treatment with a checkpoint inhibitor. The therapy is effective to treat cancers that are resistant to checkpoint inhibitors.

Antibody drug conjugates (ADC's) that bind to 191P4D12 protein and variants thereof are described herein. 191P4D12 exhibits tissue specific expression in normal adult tissue, and is aberrantly expressed in the cancers listed in Table I. Consequently, the ADC's of the invention provide a therapeutic composition for the treatment of cancer.

The present invention provides a compound having the structure:
A-B - - - Z
wherein A is a biologically active structure of the compound; wherein Z is a protein component of the compound, which protein component comprises one or more polypeptides, wherein at least one of the one or more polypeptides comprises consecutive amino acids which (i) are identical to a stretch of consecutive amino acids present in a chain of an F.sub.c domain of an antibody; (ii) bind to an F.sub.c receptor; and (iii) have at their N-terminus a sequence selected from the group consisting of a cysteine or selenocysteine; wherein the dashed line between B and Z represents a peptidyl linkage; and wherein the solid line between A and B represents a nonpeptidyl linkage, as well as intermediates dimers thereof, and processes of producing the compounds of the invention.

This invention relates to agents that bind human Siglecs having inhibitory activity in immune cells, and that neutralize the inhibitory activity of such Siglec. Such agents can be used for the treatment of cancers or infectious disease.

The disclosure relates to a method of treating cancer by administering to the subject a therapeutically effective amount of a composition comprising pyrvinium pamoate, optionally in combination with at least one additional therapeutic agent or modality.
