Study KAN-101-03 is a multi-center, double-blind, placebo-controlled Phase 2a study to examine whether KAN-101 confers protection from gluten exposure induced histological changes in the duodenum and to further evaluate the safety/tolerability of KAN-101 in adult participants (≥18 years) with CeD on a gluten free diet. Approximately 52 participants who meet study inclusion/exclusion criteria will be randomized 1:1 to receive KAN-101 or placebo.
