Larazotide

Also known as: Larazotide acetate, AT-1001, INN-202, GGVLVQPG

Research use only · not FDA-approved research only

Synthetic eight-amino-acid peptide that acts as a zonulin antagonist and tight-junction regulator, helping restore and maintain intestinal epithelial barrier function (reducing paracellular 'leaky gut' permeability). It was developed (as larazotide acetate, AT-1001 / INN-202) primarily for celiac disease as an adjunct to a gluten-free diet. It is not FDA-approved: a Phase 3 trial (CeDLara) in celiac disease was discontinued for futility, and the compound remains investigational with no approved human indication. The acetate salt form carries CAS 881851-50-9.

Coeliac disease and the intestinal barrier: mechanisms of disruption and strategies for restoration

Coeliac disease is characterised by immune-mediated damage to the small intestine in response to dietary gluten in genetically predisposed individuals. Increased intestinal permeability is a central component to its pathophysiology.

Upcoming Treatments in Celiac Disease: From Luminal Enzymes to Oral Immune Tolerance

Celiac disease (CeD) is a chronic autoimmune enteropathy triggered by dietary gluten in genetically predisposed individuals. Currently, a gluten-free diet (GFD) is the only available treatment, being effective in improving mucosal health and symptoms.
