  • Publication number: 20130344092
    Abstract: Novel uses for anti-thymocyte globulin (ATG, e.g., Thymoglobulin®) and related compositions are described. In one aspect, ATG and, optionally, TGF-? are used for in vitro generation of regulatory T cells, which are useful for cell therapy of immune-mediated conditions. In another aspect, ATG is directly administered to a subject at a low dose (e.g., less than 1 mg/kg per day) to treat an immune-mediated condition. The immune-mediated conditions include, for example, transplant rejection, graft-versus-host disease, and autoimmune diseases.

  • Publication number: 20110212086
    Abstract: The present invention provides compositions and methods for inhibiting the growth of a GITR-expressing cancer cell which cells may include, but are not limited to cells of epithelial origin such as NSCLC, prostate cancer, breast cancer, colon cancer and ovarian cancer and to treat or ameliorate the symptoms associated with the presence of these cells in a subject. Suitable compositions for use in these methods are antibodies that selectively recognize and bind to GITR (Glucocorticoid-induced TNFR-related protein) present on these cancer cells. The antibodies can be either polyclonal or monoclonal antibodies.
