  • Publication number: 20130157313
    Abstract: A human antibody or an antigen-binding fragment which binds human IL-6 receptor (hIL-6R) with a KD of about 500 pM or less and blocks IL-6 activity with an IC50 of 200 pM or less, is provided. In preferred embodiments, the antibody the antibody or antigen-binding fragment binds hIL-6R with an affinity at least 2-fold higher relative to its binding monkey IL-6R.

  • Publication number: 20130149744
    Abstract: The present invention provides methods for producing a fusion protein capable of binding vascular endothelial cell growth factor (VEGF). The methods of the invention comprise growing recombinant cells in suspension culture, wherein the recombinant cells contain an expression vector comprising a nucleic acid molecule encoding a fusion protein that binds VEGF, and isolating the fusion protein from the suspension culture. The fusion protein may comprise a VEGF receptor component having an immunoglobulin-like (Ig) domain 2 of a first VEGF receptor, an Ig domain 3 of a second VEGF receptor, and a multimerizing component.

  • Patent number: 8445434
    Abstract: A fusion protein comprising at least one IGF1 variant component and a fusion component (F), and, optionally, a signal sequence, exhibits improved stability relative to the native IGF1 or IGF2 polypeptide. The fusion component (F) may be a multimerizing component, such as an immunoglobulin domain, in particular, the Fc domain of IgG or a heavy chain of IgG. IGF1 variants were shown to have improved ability to increase muscle mass in a subject suffering from muscle atrophy caused by cachexia, immobilization, aging, chronic disease, cancer, hereditary condition, an atrophy-causing agent, and the like. IGF1 variants are also effective in decreasing blood glucose in a subject suffering from diabetes or hyperglycemia.
