SYDNEY, AUSTRALIA – 06 December 2022 – Immutep Limited (ASX: IMM; NASDAQ: IMMP) ("Immutep” or “the Company”), a clinical-stage biotechnology company developing novel LAG-3 immunotherapies for cancer and autoimmune disease, announced today that a GMP compliant manufacturing process has been established for IMP761, its proprietary preclinical candidate for autoimmune diseases. The 200L scale attained by Northway Biotech, an end-to-end biopharmaceutical contract development and manufacturing organisation (CDMO), will ensure supply of IMP761 for IND-enabling studies and ensuing clinical trials.
As the first immunosuppressive agonist antibody to LAG-3 acting upstream on activated T cells to target the root cause of self-antigen-specific T cell induced disease, IMP761 is a potential game-changer in how autoimmune diseases are treated. Pre-clinical testing of IMP761 in oligoarticular juvenile idiopathic arthritis, published in Pediatric Research in May 2021, showed that agonistic activation of LAG-3 in this Th1-driven autoimmune disease setting resulted in a decreased secretion of nearly all measured cytokines, and that of IL-10, IL-12, IL-1β, IL-4, and IL-6 reached the level of significance (p < 0.01).
