Degradation compounds include a cyclic cell penetrating peptide (cCPP) and a degradation construct. The degradation construct includes a degradation moiety and a targeting moiety. The targeting moiety binds a target protein. When the targeting moiety is bound to the target protein, the degradation moiety mediates degradation of the target protein. The cCPP facilitates transfer of the degradation construct into a cell. The degradation compound may further include an exocyclic peptide to enhance endosomal escape of the compound or degradation construct once inside the cell.

Combination therapy of a cancer with a multi-specific binding protein that bind a tumor associated antigen, the NKG2D receptor, and CD16, in combination with a second anti-cancer agent are described. Also described are pharmaceutical compositions of the multi-specific binding protein, and therapeutic methods useful for the treatment of cancer in combination with a second anti-cancer agent.

The present disclosure provides anti-DLL3 binding constructs, such as anti-DLL3 single domain antibodies, as well as polynucleotide encoding the same. Further provided are multispecific binding constructs comprising the DLL3 binding domains described herein and polynucleotides encoding the same. Methods of production of the anti-DLL3 binding constructs and their use in the treatment of cancer are also provided herein.

Antibodies, including single-domain antibodies, that bind to SARS-CoV2 virus and methods of treatment using single-do-main antibodies that bind to SARS-CoV2 virus are provided.

The present invention relates to a low-molecular antibody composed of D-amino acids and achiral glycine, a method for producing the same, and a method for screening the low-molecular antibody using a mirror-image target protein corresponding to a target protein and an antibody library.

The invention relates to isolated single-domain antibodies (sdAb) directed against von Willebrand Factor (VWF) D′D3 domain and chimeric polypeptides comprising thereof such as blood clotting factors and their uses in therapy such as in the prevention and treatment of hemostatic disorders. The invention also relates to a method of extending or increasing half-life of a therapeutic polypeptide comprising a step of adding to the polypeptide sequence of said therapeutic polypeptide at least one sdAb directed against VWF D′D3 domain.

The present invention relates to compositions and methods for the prevention or the treatment of lung cancer, wherein the compositions comprise an antibody binding to progastrin and the methods comprise the use of an antibody binding to progastrin.

The present invention relates to the field of virology, more specifically to the field of zoonotic Coronaviruses. Specifically, the invention provides for binding agents specific for the spike protein receptor binding domain (RBD) of the SARS-Corona virus, more specifically for an epitope of the RBD present in a broad range of Sarbecoviruses and mutants thereof, even more specifically present in SARS-Cov and SARS-CoV-2 viruses. More specifically, the invention relates to compositions comprising antibodies capable of specifically binding and neutralizing SARS-Corona viruses. More specifically the invention relates to compositions comprising single domain antibodies, or specifically VHHs, and compositions comprising multivalent binding agents comprising IgG Fc fusions thereof, specifically VHH-Fc fusions thereof, even more specifically comprising heavy chain only VHH72-S56A-IgG1-Fc fusions, or compositions comprising any humanized form of any one thereof, and are capable of specifically binding and neutralizing SARS-Corona viruses, specifically SARS-Cov-2 virus. The compositions are useful in the diagnosis of Sarbecoviruses, and specifically SARS-CoV-2 virus, and in prophylactic and/or therapeutic treatment of a condition resulting from infections with Sarbecoviruses, specifically SARS-Corona or SARS-CoV-2 virus, or mutants thereof.

A transgenic non-human animal is provided. In certain embodiments, the animal comprises a genome comprising an immunoglobulin heavy chain locus comprising: a) a transcribed gene encoding a fusion protein comprising, from N-terminus to C-terminus: i. a scaffold comprising a first binding domain; and ii. a heavy chain constant region operably linked to the scaffold; wherein the scaffold is capable of specifically binding to a target in the absence of additional polypeptides; and b) a plurality of pseudogenes that are operably linked to the transcribed gene and that donate, by gene conversion, nucleotide sequence to the part of the transcribed gene that encodes the binding domain.

Provided herein are VHH-containing polypeptides that bind CD33. Uses of the VHH-containing polypeptides are also provided.
