The present disclosure relates to multi-specific molecules which are capable of simultaneously binding at least two different target antigens or epitopes. The molecules comprise at least one binding domain molecule (BDM) which hinds to a first target antigen or epitope, the BDM being modified for selective binding to a heterologous target, coupled to a pharmacologically active protein or peptide which is an antibody or antigen-binding fragment thereof or a non-antibody protein or peptide which binds to a second target antigen or epitope, the BDMs being coupled to a C-terminus of a polypeptide present within the pharmacologically active protein or peptide.

The present application provides fusion proteins that comprise a cytokine fused to an albumin binding moiety. The fusion proteins may further comprise an antigen binding moiety such as a therapeutic antibody. The present application also provides methods of making and using the fusion proteins. The present application also provides methods of treatment comprises administering a fusion protein comprising a cytokine fused to a half-life extending domain and a second agent.

The present disclosure provides a multispecific antibody having increased in vivo sustainability, the multispecific antibody comprising one or more bioactive effector moieties linked to either or both of an N-terminal and a C-terminal of an antigen binding fragment Fab that binds to human serum albumin.

The present invention is directed to optimized anti-CD3 variable sequences for use in a variety of bispecific formats, including those that utilize scFv components. The invention further relates to nucleic acids encoding for the polypeptide, to vectors comprising the same and to host cells comprising the vector. In another aspect, the invention provides for a pharmaceutical composition comprising the mentioned polypeptide and medical uses of the polypeptide.

The present invention provides a method for recovering a human VH3 domain-containing antibody in monomeric form. In particular the present invention provides a new method that allows recovery of monomeric human VH3 domain-containing antibodies from a mixture containing monomeric and multimeric forms of the antibody.

The invention relates to antibodies, antibody fragments and binding agents that specifically recognize oligomeric tau but do not bind to monomeric tau, fibrillar tau or non-disease associated forms of tau.

Methods and reagents for the installation of click chemistry handles on target proteins are provided, as well as modified proteins comprising click chemistry handles. Further, chimeric proteins, for example, bi-specific antibodies, that comprise two proteins conjugated via click chemistry, as well as methods for their generation and use are disclosed herein.

The present invention relates to Chimeric Antigen Receptors (CAR) that are recombinant chimeric proteins able to redirect immune cell specificity and reactivity toward selected membrane antigens, and more particularly in which extracellular ligand binding is a scFV derived from a CD123 monoclonal antibody, conferring specific immunity against CD123 positive cells. The engineered immune cells endowed with such CARs are particularly suited for treating lymphomas and leukemia.

The disclosure relates to compounds specific for IL23A and BAFF, compositions comprising the compounds, and methods of use thereof. Nucleic acids, cells, and methods of production related to the compounds and compositions are also disclosed.

Provided herein are prostate specific membrane antigen (PSMA) targeting trispecific proteins comprising a domain binding to CD3, a half-life extension domain, and a domain binding to PSMA. Also provided are pharmaceutical compositions thereof, as well as nucleic acids, recombinant expression vectors and host cells for making such PSMA targeting trispecific proteins. Also disclosed are methods of using the disclosed PSMA targeting trispecific proteins in the prevention, and/or treatment diseases, conditions and disorders.
