Research applications

Larazotide has been studied in multiple completed human trials for celiac disease but has never received FDA or EMA approval. A Phase 1 single-dose study (Paterson et al. 2007, PMID 17697209) confirmed no systemic absorption. Phase 2 gluten-challenge trials (Leffler et al. 2012, PMID 22825365, n=86, doses 0.25/1/4/8 mg TID) did not meet the primary endpoint (intestinal permeability) due to high variability, though lower doses limited symptom worsening. A Phase 2b trial (Leffler et al. 2015, PMID 25683116, ~342 patients, no gluten challenge) met its primary endpoint at the 0.5 mg TID dose, showing symptom improvement versus placebo with an inverse dose-response. The Phase 3 CeDLara trial (NCT03569007, 307 patients, 0.25 mg and 0.5 mg TID) was terminated by the sponsor in 2022 for futility/impractically large required sample size, with no results posted. Across trials, no serious drug-related adverse events or hepatic/renal/bone toxicity signals were reported; headache and urinary tract infection were the most common adverse events without consistent excess versus placebo. In preclinical models, larazotide reduced gliadin-induced paracellular permeability and preserved tight-junction protein localization in Caco-2 human intestinal cell monolayers, prevented gliadin-induced permeability increases and reduced macrophage infiltration in HLA-DQ8 transgenic mice, and accelerated barrier recovery in a porcine jejunum ischemia-reperfusion injury model.
