CLIN1001-004 was a randomized, double-blind, placebo controlled, dose-ranging, 7-arm, multicenter study with a gluten challenge. The objects were multiple dose safety and tolerance; efficacy (intestinal permeability [change in urinary LAMA ratio] and disease signs and symptoms) following gluten challenge.~Following a 21-day screening period, subjects were randomized to one of seven treatments groups: four groups received larazotide acetate (0.25 mg, 1 mg, 4 mg or 8 mg TID) along with an 800 mg gluten challenge, one group received placebo with an 800 mg gluten challenge, a safety control arm received the highest dose of larazotide acetate (8 mg TID) and gluten placebo and the last group received drug placebo and gluten placebo. The gluten challenge was administered as capsules (800 mg TID) with each main meal for a total of 2.4 g daily. Drug or drug placebo was administered TID 15 minutes prior to each main meal. Subjects received their assigned treatments for two weeks (Day 0 through Day 14) and came to clinic for a follow-up visit one week later (Day 21). Subjects remained on their gluten-free diet for the duration of the study.
This study was run to determine the safety, tolerance, and efficacy of multiple doses of larazotide acetate in subjects with celiac disease following a gluten challenge.
