Half-Life Not established as a systemic value. Larazotide is designed to act locally in the intestinal lumen and is given orally rather than for systemic exposure (PMID: 33881350); single-dose safety, tolerance and pharmacokinetics were assessed in a phase 1b study in celiac disease subjects (PMID: 17697209) ## Administration Routes Oral Dosage Calculator Calculate exact dosing for Larazotide (AT-1001). https://www.bodyhackguide.co/tools/dosage Dosing data for Larazotide (AT-1001) is being researched. Check the compound page (https://www.bodyhackguide.co/compound/larazotide) for the latest information. ## Side Effects & Safety Tolerability in trials has been close to placebo. The phase 1b study reported no increase in adverse events against placebo (PMID: 17697209). In the 86-patient gluten-challenge study, larazotide was generally well tolerated, no serious adverse events occurred, and the most common adverse events were headache and urinary tract infection (PMID: 22825365). In the 342-patient phase 2b trial, safety was comparable with placebo (PMID: 25683116). A meta-analysis of four randomized trials in 626 patients found adverse events broadly comparable between larazotide and placebo, with less gluten-related diarrhea in treated patients undergoing gluten challenge (PMID: 34339872). In the phase 2a trial in 12 children with multisystem inflammatory syndrome, no larazotide-related adverse events were reported over 24 weeks of safety follow-up (PMID: 40737433). Contraindications No pharmacological contraindications have been established in the published trials. Mechanism-based caution: larazotide does not treat celiac disease and does not make gluten safe to eat. In every trial, patients stayed on a gluten-free diet or were given a controlled gluten challenge under supervision, and the compound was studied as an addition to the diet, not a replacement for it (PMID: 25683116). Trial exclusion criteria in the phase 3 study covered refractory celiac disease, severe complications of celiac disease and chronic active gastrointestinal disease other than celiac disease (NCT03569007).
