(Nasdaq: PGEN), today announced it has met the primary endpoint assessing safety and tolerability in the Phase 1b monotherapy portion of the ongoing Phase 1b/2a clinical study investigating AG019 ActoBiotics™ for the treatment of early-onset type 1 diabetes (T1D) (clinical trial identifier: NCT03751007, EudraCT 2017-002871-24). \n\n \n \n \n \n \n \n\n \nT1D is an autoimmune disease in which the immune system destroys insulin-producing beta cells in the pancreas, resulting in a blood glucose imbalance. There is no approved disease-modifying treatment for T1D, which is currently managed through lifestyle modification and diet combined with exogenous insulin. Replacement insulin therapy is associated with a variety of near- and long-term adverse events, as is failure to properly control glucose levels within a narrow range.\nAG019 is formulated as an oral capsule consisting of engineered Lactococcus lactis specifically modified to deliver autoantigen human proinsulin (hPINS) and the tolerance-enhancing cytokine human interleukin-10 (hIL-10) to the mucosal lining of the gastrointestinal tissues. Administration of AG019 is designed to induce specific regulatory T cells (Tregs) that could reduce or eliminate the destruction of insulin-producing cells, potentially stabilizing or improving insulin production.\nThe Phase 1b open-label portion of the study evaluates the safety and tolerability of AG019 administered as a single dose and repeated daily doses as a monotherapy in adult and adolescent patients. The primary endpoint for assessing safety and tolerability is treatment-emerging adverse events (TEAEs) reported up to six months after treatment initiation. Nineteen patients were treated in the Phase 1b monotherapy portion of the study and 17 pati...
