The present invention relates to CX3CR1-binding polypeptides, in particular polypeptides comprising specific immunoglobulin domains. The invention also relates to nucleic acids encoding such polypeptides; to methods for preparing such polypeptides; to host cells expressing or capable of expressing such polypeptides; to compositions comprising such polypeptides; and to uses of such polypeptides or such compositions, in particular for prophylactic, therapeutic and diagnostic purposes.

The present invention relates, in part, to, chimeric proteins which include the extracellular domain of transforming growth factor beta receptor (TGFBR2) and their use in the treatment of diseases, such as immunotherapies for cancer and/or an inflammatory disease.

The invention relates to a method of reducing the amount of non-aggregate produce-related impurities (NAPRIs) in a buffered solution of monoclonal antibodies (mAbs), involving the use of a synthetic depth filter. The invention may be of use in the purification of monoclonal 5 antibodies.

The present invention relates to a peptide and its use as a medicament, in particular in the treatment of metabolic syndrome, non-alcoholic fatty liver disease (NAFLD), cardiovascular disease (CVD) or cholestatic liver disease.

The present invention is directed to use of kifunensine for increasing sialylation of a glycosylated polypeptide, wherein a cell that produces the glycosylated polypeptide is contacted with kifunensine. Also provided are related methods for increasing sialylation of a glycosylated polypeptide and producing a glycosylated polypeptide, as well as glycosylated polypeptides and pharmaceutical compositions comprising the same, and their use in medicine.

Multivalent D-peptidic compounds that specifically bind to a target protein are provided. The multivalent D-peptidic compounds can include two or more distinct variant D-peptidic domains connected via linking components. The D-peptidic compounds can include multiple distinct domains that specifically bind to different binding sites on a target protein to provide for high affinity binding to, and potent activity against, the target protein. D-peptidic variant GA and Z domain polypeptides are also provided, which polypeptides have specificity-determining motifs (SDM) for specific binding to a target protein, such as VEGF-A or PD-1. In some embodiments where the target protein is homodimeric (e.g., VEGF-A, PD-1), the D-peptidic compounds may be similarly dimeric, and include a dimer of multivalent (e.g., bivalent) D-peptidic compounds. Methods for using the compounds are provided, including methods for treating a disease or condition associated with a target protein in a subject.

Provided is a fusion polypeptide comprising GDF15 (Growth/differentiation factor 15) and an Fc region of immunoglobulin, a pharmaceutical composition comprising the fusion polypeptide, and a method of increasing in vivo duration of GDF15 comprising fusing with an Fc region of immunoglobulin.

The present disclosure provides a system that enables precise temporal control of the serum half-life a therapeutic moiety by inducing the association or disassociation of the therapeutic moiety with an Fc domain by a small molecule. The present disclosure also provides a system that enables precise control of the serum half- life a T cell engager domain by incorporating a chemically induced dimerizer (CID). One half of the CID is fused to a T cell engager, and the other half of the CID is fused to a HSA binding domain. Addition or removal of a small molecule induces association or dissociation of the T cell engager with HSA, thereby enabling precise temporal control of the serum half-life the T cell engager.

The present disclosure provides novel and improved IL-15 fusion proteins for use in the treatment of cancer and other disorders. In various embodiments, the fusion proteins of the invention have two functional domains: an IL-15/IL-15RαSushi domain (also referred to herein as an “IL-15/IL-15RαSushi complex”) and an antibody domain, each of which can take different forms, and configured such that the IL-15 is fused to the C-terminal of the antibody domain and co-expressed and non-covalently complexed with IL-15RαSushi. Importantly, the fusions proteins of the present invention address several of the limitations observed with the IL-15 therapeutics evaluated to date; specifically, the fusion proteins demonstrate extended the half-life of IL-15 in vivo, and demonstrate optimized preclinical activity compared to rIL-15 or related cytokine therapeutics.

The present disclosure relates to IL12 receptor agonists with improved therapeutic profiles.
