The invention provides a process for preparing a cell-binding agent chemically coupled to a drug. The process comprises covalently attaching a linker to a cell-binding agent, a purification step, conjugating a drug to the cell-binding agent and a subsequent purification step.

The invention provides methods for treating patients with anti-α4β7 antibody comprising predicting outcome of the antibody therapy. The invention relates to the identification of patients who can respond to therapy comprising an anti-α4β7 antibody.

This disclosure features methods and compositions for treating diseases of the gastrointestinal tract with an IL-12/IL-23 inhibitor.

This disclosure features methods and compositions for treating diseases of the gastrointestinal tract with IL-10 or an IL-10 agonist.

The present invention provides a novel anti-integrin α11 monoclonal antibody that may treat a fibrotic disease. An aspect of the present invention is an anti-integrin α11 monoclonal antibody which inhibits binding between an integrin α11 and collagen.

An object of the present invention is to develop a novel treatment method for chronic diseases for which conventional treatment methods are either ineffective or for which efficacy is low. The present invention provides a pharmaceutical composition for the treatment and/or prevention of an inflammatory chronic disease that is used in combination with a biological preparation that inhibits leukocyte tissue invasion. The pharmaceutical composition of the present invention contains as an active ingredient thereof siRNA suppressing the expression of CHST15 gene that contains a structure formed by the hybridization of RNA containing the base sequence represented by SEQ ID NO: 1 with RNA complementary thereto.

The invention provides a process for preparing a cell-binding agent chemically coupled to a drug. The process comprises covalently attaching a linker to a cell-binding agent, a purification step, conjugating a drug to the cell-binding agent and a subsequent purification step.

Provided are methods and compositions for treating kidney disease, such as chronic kidney disease (CKD), in which the methods and compositions comprise antibodies or an antigen binding fragment thereof that specifically and selectively bind to human αvβ8 integrin, which was discovered, as described, to be highly expressed on kidney cells and tissue, and, in particular, diseased or fibrotic kidney tissue. The disclosed anti-αvβ8 integrin antibodies bind to human αvβ8 integrin in the kidney and block the activation of TGF-β from its latent form in kidney tissue. The anti-αvβ8 antibodies in the disclosed methods reduce, attenuate, or abrogate kidney fibrosis, which is associated with the activities of αvβ8 integrin and TGF-β in kidney tissue. The disclosed antibodies and methods effectively treat kidney disease, in particular, fibrosis associated with kidney disease, such as CKD, in individuals in need thereof.

The present invention relates to: a composition for delivering a viral antigen-derived CD8.sup.+ T cell antigen epitope or a peptide comprising same to the cytoplasm of a target cell to thereby present the epitope or peptide to major histocompatibility complex class I (MHC-1), which is an antigen-presenting molecule on the cell surface; a composition comprising same; and a use thereof.

The present invention provides a method of treating cancer with an integrin-binding-Fc fusion protein alone or in combination with IL-2 and/or an immune checkpoint inhibitor. The invention also provides composition for use in such methods.
