What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the safety and tolerability of guselkumab in people with celiac disease. Guselkumab aims to reduce the immune system's harmful reaction to gluten. It has been previously tested for moderate to severe psoriasis.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

How is the drug Guselkumab different from other treatments?

Guselkumab is unique because it specifically targets the interleukin-23 (IL-23) pathway, which plays a key role in inflammatory processes, making it different from other treatments that may target broader immune pathways. This specificity can lead to more targeted treatment with potentially fewer side effects. ^{1 2 3 4 5}

Are You a Good Fit for This Trial?

Inclusion Criteria

Have a body mass index (BMI) 16 to 45 kilogram per meter square (kg/m^2). Underweight participants (BMI 16 to 18 kg/m^2) may only be included if in the opinion of the investigator a participant was underweight due to active celiac disease and thus, may benefit from therapy but yet not be at significantly increased risk due to severe malabsorption or other conditions

Physician-diagnosed celiac disease with documented history of biopsy-proven celiac disease

Self-reported to be on a gluten-free diet (GFD) for at least 11 consecutive months prior to enrollment and have the willingness to continue to adhere to the same GFD while on study

How Is the Trial Designed?

Group I: Module B (With Gluten-Challenge): Guselkumab or Placebo Experimental Treatment 2 Interventions

Participants in Module B (with gluten-challenge) will receive IV infusion of guselkumab or matching placebo as induction dose at every 4 weeks through Week 8 followed by SC injection of guselkumab or matching placebo at Week 12.
