Response: Celiac disease (CeD) is a common intestinal inflammatory disease that affects about 1% of most wheat consuming populations worldwide. CeD is caused by the ingestion of gluten containing foods, such as wheat, spelt, rye and barley, that activate small intestinal inflammatory T cells. The only current therapy is the rigorous avoidance of even traces of gluten in the daily diet, which is difficult and a social and psychological burden. We previously identified the body’s own enzyme tissue transglutaminase (TG2) as the CeD autoantigen. Moreover, TG2 drives celiac disease pathogenesis by enzymatically modifying dietary gluten peptides that makes them more immunogenic. We therefore developed an oral small molecule (ZED1227) that specifically inhibits TG2 activity in the intestine. While this should attenuate CeD in patients exposed to dietary gluten, it was unclear if  it could prevent gluten induced intestinal inflammation and damage. (more…)
