Larazotide: What It Is and Its U.S. Regulatory Status

What is larazotide?

Larazotide, also called larazotide acetate, is a synthetic peptide made of eight amino acids. It was designed to act on tight junctions, the seals between cells that line the intestine and control what passes through the gut wall.

Larazotide has been studied in clinical trials for celiac disease, an immune condition triggered by gluten. It has not been approved for that or any other use.

U.S. regulatory status

Current status: Investigational – not FDA-approved.

Investigational means larazotide has been tested in clinical research but has not been approved by the FDA. It is not available as a prescription medicine in the United States.

People who want to know the current state of larazotide research can search for it on ClinicalTrials.gov, the public U.S. registry of clinical studies.
