Larazotide acetate
Also known as: AT-1001 ยท INN-202
Grade describes the published research on the molecule. It is not a quality score, a safety score, or a release state.
What this is
Larazotide acetate is a defined synthetic peptide developed for local oral activity at intestinal tight-junction signaling. AT-1001 and INN-202 are development names found in the literature.
Evidence position
Several controlled human studies support Grade B. Results vary by dose and endpoint, so the page keeps positive, null and exploratory findings in the same record.
What the record does not establish
Clinical-trial material does not authenticate a supplier lot, a capsule sold under a similar name, or any route and formulation outside the studied protocol.
