Nearly 1.6 million Americans have Type 1 Diabetes (T1D), an autoimmune class of diabetes. Additionally, ~3.2 million Americans develop latent autoimmune diabetes of adults (LADA). For T1D or LADA patients, immunotherapy promises a path to reprogram the immune system such that it no longer attacks and destroys insulin-producing beta cells in the pancreas. SermAb Biologics is developing a monoclonal antibody therapy against serpinB13. SermAb Biologics focuses on the discovery that tissue regeneration is stimulated by blocking serpinB13 and restoring the activity of its protease target. The second advantage is that our antibody to serpinB13 suppresses inflammation, increases beta-cell proliferation, and delays the onset of diabetes. Thus, by using a single reagent that regulates the balance between serpin inhibitor and protease, we can simultaneously suppress the inflammatory response while promoting regenerative changes in the pancreas and other tissues expressing serpinB13.
