Study Summary

This trial is testing a drug to treat celiac disease in HLA-DQ2.5 & DQ8+ people aged 18-75 who are gluten-free for 6+ months & have inactive disease.

Who is the study for?
Adults aged 18-75 with confirmed inactive celiac disease, on a gluten-free diet for at least 6 months, and positive for HLA-DQ2.5 or HLA-DQ8 can join this trial. They must not drink too much grapefruit juice, agree to contraception if applicable, avoid strenuous exercise before visits, have no recent surgeries or need for upcoming surgery, and test negative for SARS-CoV-2.Check my eligibility
What is being tested?
The trial is testing the safety and effectiveness of Ritlecitinib in people with celiac disease who are in remission. Participants will either receive Ritlecitinib plus gluten or a placebo plus gluten to see how well they tolerate the reintroduction of gluten into their diet.See study design
What are the potential side effects?
Potential side effects from Ritlecitinib may include immune system changes leading to increased infection risk, possible liver issues indicated by blood tests changes, headaches, nausea and potential allergic reactions.

Other Research
The primary treatment for Celiac Disease is a strict gluten-free diet, which eliminates the ingestion of gluten, thereby preventing the autoimmune response that damages the small intestine. Emerging treatments, such as Janus kinase (JAK) inhibitors like Ritlecitinib, work by blocking specific pathways involved in the inflammatory response. JAK inhibitors can potentially reduce the immune-mediated damage to the intestinal lining, offering an alternative for patients who do not fully respond to a gluten-free diet. This is significant for Celiac Disease patients as it provides a potential therapeutic option to manage symptoms and intestinal damage more effectively.
