A LAG-3–Specific Agonist Antibody for the Treatment of T Cell–Induced Autoimmune Diseases

). IMP761 inhibits TCR-mediated NFAT activation and Ag-induced human T cell proliferation and activation. In the DTH model, assessment of T cell infiltration and gene expression profile at the DTH biopsy site corresponds to immunosuppression of an Ag-induced T cell response. IMP761 is the first LAG-3-specific agonist product candidate, acting upstream on activated T cells, the root cause of self-Ag-specific T cell-induced autoimmune diseases.
