A Decentralized Home-Based Study To Investigate Novel Objective Biomarker Of Gluten-Mediated Symptoms In Celiac Disease Participants (CeDar ROSE Study)

Completed
Conditions
Celiac Disease
Registration Number
NCT05686369
Lead Sponsor
Chugai Pharmaceutical
Brief Summary

This is a decentralized study to primarily explore a novel objective digital biomarker (i.e., Gluten Dependency Index) for celiac disease-related responses triggered by gluten exposure using a wearable biosensor. This study also explores a novel objective blood biomarker specific to celiac disease activity and evaluates participant symptoms, lifestyle and an objective comprehensive measurement (e.g., activity, stress and sleep) in celiac disease participants.

Approximately 170 well-controlled celiac disease participants (Cohort A) and 40 celiac disease participants with persistent symptoms (Cohort B) will be monitored for 13 and 8 weeks in the observation period, respectively, in a home-based setting using the wearable biosensor along with a mobile platform including some electronic questionnaires.

The wearable biosensor continuously records biosensor data. These data will be used to develop a new algorithm for Gluten Dependency Index and calculate the Gluten Dependency Index, Activity Value, Stress Value, or Sleep Time. Participants will report celiac disease-related symptoms, diet (including any accidental gluten exposures), exercise, menstruation questionnaires in CDSD and mobile platform questionnaire (MPFQ), which is originally designed by the Sponsor.

All participants both in Cohort A and B are required to maintain gluten-free diet throughout the study. Only participant who are enrolled in Cohort A will be required gluten challenge.

Inclusion Criteria

[Cohort A and B]

  • History of medically diagnosed celiac disease based on biopsies and positive celiac serology.
