The invention provides an antibody or antigen binding fragments thereof that binds to 3pE Aβ and methods of making and using the antibody or antigen binding fragment thereof, including use for formulations, administration and kits. The antibody and antigen binding fragments thereof and methods disclosed are useful for diagnosis, prognosis and treatment of Alzheimer's disease or other β-amyloid-related diseases.

The present application provides a recombinant fusion protein containing an anti-PD-L1 antibody or an antibody fragment thereof, with each paratope of the anti-PD-L1 antibody or antibody fragment thereof linked via a linker to an extracellular Ig-like domain of a signal-regulatory protein (SIRP) at N-terminus of a heavy chain variable region or a light chain variable region constituting the paratope, wherein the recombinant fusion protein can bind to CD47, PD-L1 and FcR simultaneously. The present application also provides a nucleic acid molecule encoding the recombinant fusion protein, an expression vector containing the nucleic acid molecule, a method for producing the recombinant fusion protein and a method for treating a disease associated with over-expression of CD47 and/or PD-L1 using the recombinant fusion protein.

Novel antibodies and antigen binding fragments that specifically bind to KAAG1 and which may be used in the treatment, detection and diagnosis of cancer comprising KAAG1-expressing cells are disclosed herein. Cells expressing the antibodies and antigen binding fragments as well as methods of detecting and treating cancer using the antibodies and fragments are also disclosed. Cancer indications which may benefit from such treatment or detection include ovarian cancer, renal cancer, lung cancer, colorectal cancer, breast cancer, brain cancer, and prostate cancer, as well as melanomas.

The inventors discovered that by administering a pharmaceutical composition comprising a bispecific antigen-binding molecule that recognizes blood coagulation factor IX and/or activated blood coagulation factor IX and blood coagulation factor X and/or activated blood coagulation factor X according to a given dosage regimen, diseases that develop and/or progress due to a decrease or deficiency in the activity of blood coagulation factor VIII and/or activated blood coagulation factor VIII can be prevented and/or treated more effectively.

The present invention provides monoclonal antibodies that bind to the complement factor 5 (C5) protein, and methods of use thereof. In various embodiments of the invention, the antibodies are fully human antibodies that bind to C5 protein. In some embodiments, the antibodies of the invention are useful for inhibiting or neutralizing C5 activity, thus providing a means of treating or preventing a C5-related disease or disorder in humans. In some embodiments, the invention provides for an anti-C5 antibody that has improved pharmacokinetic and pharmacodynamic properties, e.g., a half-life of more than 10 days.

Purified recombinant polypeptides isolated from Chinese hamster ovary host cells, including antibodies, such as therapeutic antibodies, and methods of making and using such polypeptides are provided.

Provided are chimeric or recombinant antibodies (Ab), or antigen binding fragments thereof, or monomeric or dimeric antigen binding proteins, that can specifically bind to human LAG-3 polypeptides, including human LAG-3 polypeptides expressed on the surface of lymphocytes such as activated T cells that have infiltrated tumors or tumor infiltrating lymphocytes (TILs), and methods for making and using them. In alternative embodiments, chimeric or a recombinant antibodies (Ab), or antigen binding fragments thereof, or monomeric or dimeric antigen binding proteins as provided herein are used for in vitro diagnostics, for example, in immuno-histochemistry (IHC), for example, to diagnose and/or treat a cancer, for example, bladder cancer, urothelial carcinoma, breast cancer, lung cancer, Non-Small Cell Lung Cancer, renal carcinoma, Renal Clear cell Carcinoma and/or melanoma or malignant melanoma, by their ability to specifically bind to activated T cells that have infiltrated tumors, or tumor infiltrating lymphocytes.

The present disclosure provides antibodies that specifically bind to human OX40 receptor (OX40) and compositions comprising such antibodies. In a specific aspect, the antibodies specifically bind to human OX40 and modulate OX40 activity, e.g., enhance, activate, or induce OX40 activity, or reduce, deactivate, or inhibit OX40 activity. The present disclosure also provides methods for treating disorders, such as cancer, by administering an antibody that specifically binds to human OX40 and modulates OX40 activity, e.g., enhances, activates, or induces OX40 activity. Also provided are methods for treating autoimmune or inflammatory diseases or disorders, by administering an antibody that specifically binds to human OX40 and modulates OX40 activity, e.g., reduces, deactivates, or inhibits OX40 activity.

An antibody-drug conjugate having a structure represented by formula (I)

##STR00001##

wherein m is 1, 2, 3, or 4 and Ab is an anti-glypican-3 antibody having heavy and light chain CDRs as disclosed herein.

Compositions and methods are described for stabilizing a radio-iodinated monoclonal IgG antibody for up to 17 days against radiolytic decomposition. The stabilized radiolabeled murine antibody binding the CD45 antigen expressed on various forms of lymphomas is useful as a radio-therapeutic and diagnostic agent in the treatment of human malignancies of hematopoietic origin, including lymphomas.
