  • Publication number: 20240368239
    Abstract: The present invention relates to a novel bispecific fusion protein and a use thereof. More specifically, the present invention relates to: a bispecific fusion protein in which a GLP-1 analogue and a GLP-2 analogue are fused, or a bispecific fusion protein comprising a first fusion protein in which a GLP-1 analogue is linked to an antibody Fc region and a second fusion protein in which a GLP-2 analogue is linked to an antibody Fc region, wherein the bispecific fusion protein is produced by dimerization of the first fusion protein and the second fusion protein; and a pharmaceutical composition comprising same as an active ingredient, for the treatment of a disease or symptom requiring intestinal proliferation or metabolic diseases such as obesity, type 2 diabetes, and nonalcoholic steatohepatitis.

  • Patent number: 11524054
    Abstract: The present invention relates to a method for treating anemia using a long-acting EPO formulation, and more specifically, a method for treating patients with anemia by confirmation of safe, long-acting, and optimal effective dosage and usage in administering a fusion polypeptide which comprises an EPO and an immunoglobulin hybrid Fc to patients with anemia. The method of administering the fusion polypeptide employs an appropriate dosage and usage which not only shows an excellent long-acting property compared to the existing EPO products but also minimizes cardiovascular side effects that may occur due to a rapid increase in hemoglobin level, which is an effect of anemia treatment.

  • Publication number: 20220305086
    Abstract: A method for increasing a lymphocyte count in a subject in need thereof including administering to the subject (i) a modified interleukin-7 of the following formula (I): A?IL-7 wherein A is an oligopeptide consisting of 1 to 10 amino acid residues, and the IL-7 is a polypeptide which is capable of binding to IL-7 receptor; or (ii) an interleukin-7 fusion protein comprising (a) the modified interleukin-7, (b) a second domain containing an oligopeptide having 1 to 10 amino acid residues consisting of methionine, glycine, or a combination thereof; and (c) a third domain which prolongs the half-life of the interleukin-7 fusion protein.

  • Patent number: 10538569
    Abstract: The present invention relates to a fusion polypeptide containing a glucagon-like peptide (GLP) and an immunoglobulin hybrid Fc, and more specifically, to a fusion polypeptide with an increased half-life and improved efficacy compared to the conventional fusion polypeptide based on the discovery of an immunoglobulin hybrid Fc suitable for GLP or analogs thereof, and a pharmaceutical composition for treating diabetes, inflammatory bowel disease, endoenteritis or diarrhea caused by anticancer chemotherapy, or short bowel syndrome, containing the fusion polypeptide. The fusion polypeptide of the present invention has an increased half-life and improved resistance to DPP-4 enzyme compared to those of GLP-1 and GLP-2, and it thus has improved drug efficacy in treating diabetes, inflammatory bowel disease, endoenteritis or diarrhea caused by anticancer chemotherapy, or short bowel syndrome, compared to those of the conventional drugs.
