A Study of Efficacy, Safety, and Tolerability of KAN-101 in People with Celiac Disease

Phase 2

Completed

• Conditions: Celiac Disease; Coeliac Disease
• Interventions: Drug: KAN-101; Drug: Placebo

• Registration Number: NCT06001177
• Lead Sponsor: Kanyos Bio, Inc., a wholly-owned subsidiary of Anokion SA

Brief Summary

The study goal is to evaluate the efficacy, safety, and tolerability of KAN-101 in participants with Celiac Disease (CeD)

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method

Secondary Outcome Measures

Name	Time	Method
Incidence of KAN-101 ADA	42 days	ADA is antidrug antibody
Change in magnitude of IL-2 response from Day 15 (first day of GC) pre GC to Day 15 post GC	15 days	IL-2 is interleukin-2
Incidence and severity of treatment emergent adverse events as assessed by the CTCAE	42 days	Common Terminology Criteria for Adverse Events (CTCAE) is a scale with 5 grades to assess Adverse Event (AE) severity
Titer of KAN-101 ADA	42 days	ADA is antidrug antibody
KAN-101 plasma concentration: AUCinf	7 days	Pharmacokinetic (PK) sample collection at pre and post dose timepoints
KAN-101 plasma concentration: AUClast	7 days	PK sample collection at pre and post dose timepoints
KAN-101 plasma concentration: Cmax	7 days	PK sample collection at pre and post dose timepoints
KAN-101 plasma concentration: Tmax	7 days	PK sample collection at pre and post dose timepoints
KAN-101 plasma concentration: T1/2	7 days	PK sample collection at pre and post dose timepoints
