This disclosure provides a multimeric hepatitis B virus (HBV) protein binding molecule, e.g., a dimeric IgA or a pentameric or hexameric IgM binding molecule, comprising at least two bivalent binding units, or variants or fragments thereof, each comprising at least two antibody heavy chain constant regions or fragments thereof, wherein each heavy chain constant region or fragment thereof is associated with an HBV antigen binding domain. The disclosure also provides compositions comprising the multimeric binding molecules, polynucleotides encoding the multimeric binding molecules, and methods to make and use the multimeric binding molecules.

Disclosed herein are inducible monovalent target-binding proteins which are activated upon protease cleavage. Pharmaceutical compositions comprising the binding proteins disclosed herein and methods of using such formulations are further provided.

The present invention provides bispecific antigen-binding molecules characterized by comprising a first and a second domain, each binding to any of CS1, BCMA, CD20, CD22, FLT3, CD123, CLL1, MSLN, CDH3 or EpCAM, a third domain binding to an extracellular epitope of the human and the Macaca CD3ε chain and optionally a fourth domain, which is a Fc modality. Moreover, the invention provides a polynucleotide, encoding the antigen-binding molecule, a vector comprising this polynucleotide, host cells, expressing the construct and a pharmaceutical composition comprising the same.

Provided is an immunoconjugate useful in inhibiting tumor growth, and a composition and/or protein mixture comprising the immunoconjugate. Also provided are methods for the production of the immunoconjugate, as well as pharmaceutical uses of the immunoconjugate in inhibiting tumor growth, including but not limited to treatment of cancers.

The present invention relates to treatment methods for leukemia using bispecific antibody constructs that specifically bind to human CD33 and human CD3. In particular, the present invention relates to methods for treating myeloid leukemia, including relapsed/refractory myeloid leukemia, in a patient in need thereof comprising administering to the patient at least one initiation cycle and at least one maintenance cycle of an anti-CD33×anti-CD3 bispecific antibody construct, wherein each initiation cycle and maintenance cycle comprises administering the bispecific antibody construct according to specific dosage regimens. Pharmaceutical compositions comprising the bispecific antibody constructs for use in the methods are also disclosed.

The present invention relates to artificial Antigen Presenting Cells (aAPCs) comprising artificial Antigen Presenting Molecules (aAPMs) and, in particular, comprising dimers of the aAPMs as well as to methods for producing aAPCs. The invention further relates to compositions comprising the aAPCs and to vectors encoding the aAPMs of the aAPCs. Embodiments of the invention have been particularly developed for use in assays for determining an antigen-specific T cell response or a plurality of antigen-specific T cell responses and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use.

The present invention relates to binding molecules comprising two polypeptide chains, wherein the peptide chains comprise modified EHD2 domains allowing heterodimerization only, thereby preventing homodimers, nucleic acids encoding such binding molecules and uses of such binding molecules or nucleic acids encoding such binding molecules in therapy.

The invention relates to antibody conjugates (e.g., a bispecific antibody), drug and nanoparticle compositions and methods and compositions for generating them. This invention further relates to methods of using these compositions to image, diagnose or treat a disease.

A composition containing, as active ingredients, probiotics and a polypeptide with a binding ability to IgE is disclosed. In particular, a synergistic effect of remarkably decreasing food allergy was identified at the time of combined administration of probiotics and a recombinant protein containing an extracellular domain of an alpha subunit of an IgE Fc receptor. Therefore, it is expected that the composition is highly industrially applicable due to being able to exhibit a remarkable therapeutic effect on an IgE-mediated allergic disease as compared with conventional pharmaceutical compositions.

Provided herein are trispecific antibodies that include a) a first monomer, b) a second monomer, and c) a light chain. The first monomer includes a first variant Fc domain and a variable heavy domain, the second monomer includes a second variant Fc domain and a first scFv domain and the light chain includes a variable light domain. The variable heavy domain and the variable light domain form an antigen binding domain. The trispecific antibody further includes a second scFv domain on either the first or second monomers.
