A Study of Safety, Tolerability, Pharmacodynamics, and Pharmacokinetics of KAN-101 in Celiac Disease (ACeD-it)

The study is a 3-part, multicenter Phase 1b/2 study of KAN-101 in participants with Celiac Disease (CeD) on a gluten free diet (GFD). The 3 parts include:

• Part A - Open-label, multiple ascending dose

• Part B - Double-blind, placebo-controlled, parallel design

• Part C - 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 12 participants who meet study inclusion/exclusion criteria will receive 1 of 2 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.

Parts B and C are 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. Approximately 16 participants (4 participants per dose group) will be enrolled in Part B and 104 participants (26 participants per dose group) enrolled into Part C. Participants 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 based on information obtained from Part A.
