What Larazotide is
An investigational gut-barrier peptide for celiac disease that reached Phase 3 but was terminated by the sponsor without a published result.
Larazotide acetate is an orally active peptide that tightens the intestinal barrier by acting as a zonulin antagonist, aiming to reduce the leaky-gut response to gluten in celiac disease. It advanced to Phase 3, but the pivotal trial was terminated by the sponsor without a published result, and it is not approved.
Mechanism: Antagonizes zonulin signaling to strengthen intestinal tight junctions and limit passage of gluten fragments across the gut lining.
Regulatory history: Investigational; Phase 3 did not meet primary endpoint
