Study type | Interventional |
This study aims to investigate how knowledge of gluten immunogenic peptide (GIP) levels in stool and urine affects subsequent adherence to a gluten-free diet. Half of the participants will receive results in real-time using a home device and the other half will store samples to be tested at the end of the 30 week study. Participants will also have a diet review with a dietitian at the beginning of the end of their study and be asked questions about their symptoms, gluten-free diet adherence and quality of life.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Difference in frequency of gluten exposure in open results vs blinded groups following randomization. | Gluten exposure frequency is defined as the average per individual subject post-randomization percentage of samples collected between weeks 8 and 30 with detectable gluten immunogenic peptides using the qualitative assay (Gluten Detective) | Weeks 8 to 30 | |
Secondary | Difference in quantity of mean gluten exposure following randomization in blinded vs. open results groups | Mean gluten exposure is defined as the average per individual subject post-randomization concentration of gluten immunogenic peptides detected using the quantitative assay | weeks 8 - 30 | |
Secondary | Celiac disease symptom score in blinded vs. open results group at the end of the study | Symptom score (using the Celiac Disease PedsRO or ObsRO as appropriate for age) at week 30 | Week 30 | |
Secondary | Change in symptom score in blinded vs. open results group | Symptom score (using the Celiac Disease PedsRO or ObsRO as appropriate) and the change in symptom score between the end of the run-in period (week 8) and the end of the study period (week 30) will be calculated arithmetically. | weeks 8 and 30 | |
Secondary | Change in celiac disease specific quality of life as measured by Celiac Disease DUX (CDDUX) in blinded vs. open results groups | The CDDUX is a disease specific quality of life instrument for children with celiac disease. | weeks 8 and 30 | |
Secondary | Change in pediatric health related quality of life as measured by PedsQL 4.0 generic core scale in blinded vs. open results groups | The PedsQL 4.0 Generic Core is a validated pediatric general quality of life measure that is caregiver reported for younger children and both child and caregiver reported for older children. The score is scaled from 0 (lowest) to 100 (highest) with higher scores corresponding to better health related quality of life. | weeks 8 and 30 |
