Study summary

This study was conducted to evaluate the efficacy of multiple doses of larazotide acetate in preventing intestinal permeability changes induced by a 6- week gluten challenge in subjects with celiac disease.

Read the detailed description

This was a Phase IIb, randomized, double-blind, placebo-controlled, dose ranging, multicenter Study to determine the safety, tolerance, and efficacy of larazotide acetate in subjects with celiac disease during a gluten challenge. Subjects remained on their gluten-free diet throughout the duration of the trial. Study drug or drug placebo capsules were administered TID 15 minutes before each meal. Gluten or gluten placebo capsules will be taken TID with each meal.

What researchers measure

Primary outcomes

  1. Efficacy of multiple doses larazotide acetate in preventing intestinal permeability changes induced by a 6- week gluten challenge.

    The primary efficacy endpoint was the Day 49 to Day 7 ratio of urinary LAMA ratios as a response to gluten

    Time frame: Following ingestion of a solution of lactulose and mannitol; lactulose and mannitol excretion was quantified and the LAMA ratio calculated from overnight urine specimens collected on Days 7, 21, 35, 49 and 56.

Secondary outcomes

  1. Safety of a 6-week exposure to oral doses of larazotide acetate in celiac disease patients exposed to 900 mg gluten TID with meals

    Safety endpoints assessed in this study were adverse events, vital signs, physical examination results, clinical laboratory test results, concomitant medication usage and ECG results

    Time frame: Up to 6 weeks

  2. To prospectively validate a composite, weighted index of celiac disease activity

    Gastrointestinal symptoms were assessed by the GSRS patient self-assessment questionnaire

    Time frame: GSRS was completed weekly throughout the study.
