Abstract: The present invention relates to a pharmaceutical composition including a polypeptide, and more particularly, to a pharmaceutical composition for preventing or treating obesity, diabetes, or non-alcoholic fatty liver disease. The pharmaceutical composition is safe without any side effects such as vomiting or nausea, and has effects of reducing food intake, enhancing insulin secretion, suppressing gastric emptying, promoting lipolysis, and lowering a level of triglycerides.

Abstract: Disclosed is a protein complex, comprising a physiologically active polypeptide, a dimeric protein and a non-peptidyl polymer having three functional ends (3-arm), with the linkage of both the physiologically active polypeptide and the dimeric protein to the 3-arm non-peptidyl polymer via respective covalent bonds. The protein complex guarantees the long acting activity and biostability of a physiologically active polypeptide. Having the ability to maintain the bioactivity of physiologically active polypeptides or peptides highly and to significantly improve the serum half life of the polypeptides or peptides, the protein complex can be applied to the development of sustained release formulations of various physiologically active polypeptide drugs. Also, it utilizes raw materials including the physiologically active polypeptides without significant loss, thereby increasing the production yield. Further, it can be easily purified.

Abstract: An insulin conjugate having improved in vivo duration and stability is provided. The conjugate is prepared by covalently linking insulin with an immunoglobulin Fc region via a non-peptidyl polymer, a long-acting formulation comprising the same, and a preparation method thereof. The insulin conjugate of the present invention maintains in vivo activity of the peptide at a relatively high level and remarkably increases the serum half-life thereof, thereby greatly improving drug compliance upon insulin treatment.
