  • 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: 20100196370
    Abstract: The present invention relates to an LK8-Fc fusion protein, which has increased angiogenesis inhibitory activity and in vivo stability. More specifically, relates to an LK8-Fc fusion protein in which an LK8 protein having angiogenesis inhibitory activity is fused with the Fc region of human immunoglobulin IgG1, as well as a composition for treating cancer, which contains the fusion protein. The LK8-Fc fusion protein has not only angiogenesis inhibitory activity leading to anticancer and metastasis inhibitory activities, but also a very long in vivo half-life, and thus can be used as a more efficient and economic cancer therapeutic agent or cancer inhibitor.

  • Publication number: 20090305965
    Abstract: Disclosed relates to a stabilized parathyroid hormone (PTH) comprising a buffer and a stabilizing agent and, more particularly, to a stabilized PTH composition in which succinic acid, malic acid, histidine or ammonium bicarbonate is used as the buffer and sorbitol or mannitol is used as the stabilizing agent. The PTH composition of the present invention can be used to formulate stably PTH protein that is much more unstable to be readily decomposed than normal low molecular weight drugs.

  • Patent number: 6692735
    Abstract: The present invention relates to a variant of Lkn-1(shLkn-1) with enhanced biological activity, which is a truncated form of Lkn-1, a process for preparing a recombinant shLkn-1 by employing expression vector therefor and pharmaceutical application of the said protein. shLkn-1 is generated by missing 26 amino acid residues from the amino terminus of Lkn-1 to contain 66 amino acids. Recombinant shLkn-1 inhibits colony formation and cell proliferation in vivo, which suggests that it can be used as a potential drug for the antibody production, the treatment during HIV-1 infection, the protection of bone marrow stem cells during chemotherapy or radiotherapy, and the inhibition of leukemia.
