The present invention provides binding proteins, such as antibodies and antigen-binding fragments, which specifically bind to human IL-36 cytokines, IL-36α, IL-36β, and/or IL-36γ, and block the IL-36 stimulated signaling pathways. Compositions comprising such binding proteins and methods of making and using such binding proteins are also provided.

Provided are proteins comprising a variant IgG Fc region, wherein the proteins exhibit significantly reduced binding to human FcγRI when compared with a reference protein comprising the amino acid substitutions L234A/L235A/P329G. Also provided are compositions, methods of treatment and methods to reduce Fc-induced effector functions in a parent protein.

The present invention pertains to humanized anti-Lewis Y antibodies which specifically bind to Lewis Y and do not show any cross-reactivity. Especially, the humanized anti-Lewis Y antibodies do not bind to Lewis b or any other blood group carbohydrate antigen. In particular, the present invention is directed to humanized anti-Lewis Y antibodies which are useful in the treatment of cancer.

This invention relates generally to antibodies that bind to human B and T lymphocyte attenuator (BTLA) and uses thereof. More specifically, the invention relates to agonistic antibodies that bind human BTLA and modulate its activity, and their use in treating inflammatory, autoimmune and proliferative diseases and disorders. Suitably, the antibodies also possess an Fc modification that enhances signalling through FcγR2B.

Hidradenitis suppurativa can be treated by administering a pharmaceutical composition that includes a pharmaceutically acceptable carrier and a therapeutically effective amount of an agent that selectively binds IL-1α.

The present disclosure provides methods for preventing, alleviating, or treating cytokine release resulting from administration of a VEGF inhibitor or side effects resulting from the cytokine release. To prevent, alleviate, or treat cytokine release or its side effects, the disclosure also provides combination therapies that use a lymphocyte-stimulating pharmaceutical agent, represented by an anti-T cell antigen-binding molecule, with a VEGF inhibitor. Among the anti-T cell antigen-binding molecules, for example, antibodies that recruit T cells as effector cells into tumor tissues are called T cell redirecting antibodies, and are known as means for treating tumors. On the other hand, when systemic cytokine production is stimulated by binding of antibodies to T cells, it is feared that this systemic action will lead to aberrations such as CRS. The present disclosure provides means for alleviating systemic cytokine production, and will enable safer use of anti-T cell antigen-binding molecules in tumor treatment.

Embodiments of the disclosure include methods and compositions directed to targeting of cells that express the long form of Bone marrow stromal cell antigen 2 (BST2) protein, including cancer cells that express the long isoform of BST2. In particular embodiments, monoclonal antibodies or functionally active fragments thereof are utilized to target cells that express the long isoform of BST2. The monoclonal antibodies or functionally active fragments thereof may be utilized by themselves or as part of other entities, such as cells or engineered antigen receptors. The disclosure includes methods of treatment, prevention, and/or diagnosis using the encompassed antibodies or functional fragments thereof.

The present application provides antibodies including antigen-binding fragment thereof that specifically recognizing Granulocyte-Macrophage Colony Stimulating Factor Receptor (GM-CSFRα). Also provided are methods of making and using these antibodies.

The present disclosure provides a site-specific protein conjugate and the method for preparation of the same. The protein conjugate comprising a protein and an oligosaccharide, wherein said oligosaccharide comprises

##STR00001##

wherein: said GlcNAc is directly or indirectly linked to an amino acid of said protein; said Gal is a galactose; said (Fuc) is a fucose, b is 0 or 1; said Fuc* comprises a fucose or a fucose derivative linked to a molecule of interest (MOI), said protein comprises an antigen binding fragment and/or a Fc fragment.

The present application provides an isolated PD-L1 binding molecule, specifically, an isolated PD-L1 single-domain antibody or an antigen-binding fragment thereof. The present invention also provides a nucleic acid encoding the isolated PD-L1 binding molecule, an expression vector or host cell comprising the nucleic acid, and a pharmaceutical composition or kit comprising the PD-L1 binding molecule.
