The study is a 2-part, multicenter Phase 1b/2 study of KAN-101 in participants with Celiac Disease (CeD) on a gluten free diet (GFD). The 2 parts include:~Part A - Open-label, multiple ascending dose~Part B - Double-blind, placebo-controlled, parallel design~Part A is a Phase 1b, open-label, multiple ascending dose (MAD) study design to assess the safety, tolerability, and pharmacokinetics (PK) of KAN-101 in adult participants (18 to 70 years inclusive) with histology-confirmed CeD. Up to 18 participants who meet study inclusion/exclusion criteria will receive 1 of 3 dose levels of KAN-101. The overall study duration will be about 56 days, including up to 28 days of screening, 7 days of treatment and 21 days of follow up. There will be a gluten challenge test (GC) on Day 15.~Part B is a Phase 2, double-blind, placebo-controlled, parallel design study to characterize the biomarker response following GC, safety, tolerability, and PK of KAN-101 in adult participants with histology-confirmed CeD. 120 participants (30 participants per dose group) will be randomized 1:1:1:1 and stratified by participation in a biopsy substudy to 4 treatment groups: placebo and 3 treatment groups with KAN-101 doses to be determined based on information obtained from Part A.
This study is to evaluate the Pharmacodynamic (PD), safety, tolerability, Pharmacokinetic (PK), and plasma biomarker response of KAN-101 in participants with Celiac Disease (CeD).
