Living with celiac disease?

You may qualify for this phase 2 clinical trial.

This study is evaluating a potential new treatment for celiac disease. Eligible participants will receive compensation for time and study-related travel.

Requirements

18 – 70 years old

Diagnosed with biopsy-confirmed celiac disease for 12+ months

On a gluten-free diet for 12+ months

About

In this study, Forte Biosciences is exploring whether FB102 can safely and effectively help adults with celiac disease. FB102 is an investigational antibody designed to block the immune responses that cause intestinal damage and symptoms when people with celiac disease ingest gluten.

What to expect with participation in this research study:

If you qualify and choose to participate, you will attend up to 16 visits over a period of about 8 months.

You will be closely monitored for any study treatment effects and changes in your symptoms throughout the entire study.

Participation Includes:

Screening (up to 45 days; 1 visit)

Eligibility assessment, medical record review, physical exam, lab tests, ECG (heart test), and upper endoscopy with biopsy.

Treatment (11 weeks)

  • Receive 8 infusions of either FB102 or placebo
  • During an 8-week gluten challenge, consume 8 grams of gluten daily for 2 weeks, then 3 grams of gluten daily for 6 weeks, and record symptoms in a daily diary.
  • Undergo a second endoscopy with biopsy.

Safety Follow-Up (15 weeks)

Health monitoring through physical exams, lab tests, and ECGs (heart tests).

FAQs

What is the study drug (FB102)?2025-12-02T16:20:53-08:00

FB102 is an antibody designed to block interleukin-2 (IL-2) and interleukin-15 (IL-15). In celiac disease patients, gluten consumption results in the production of IL-2 and IL-15 which triggers intestinal inflammation, leading to destruction of intestinal cells. The goal of FB102 is to reduce intestinal damage and symptoms attributed to celiac disease after gluten consumption.

How will the study drug be administered?2025-12-02T16:21:06-08:00

FB102 is administered as an intravenous induction (IV placed into vein), which takes 1 hour to administer. You will remain at the clinic for 1 hour following each dose for observation. You will receive a total of 8 doses of the study drug or placebo.

Has the study drug been tested in humans before?2025-12-02T16:21:23-08:00

Yes. FB102 has been tested in healthy people and in a small number of patients with celiac disease in previous studies, and the drug was shown to be safe and well-tolerated.

What is a placebo, and why is it used?2025-12-02T16:21:44-08:00

A placebo is an inactive substance with no therapeutic effect that is used to help determine whether results are due to the study drug.

What is a clinical trial?2025-12-02T16:21:53-08:00

A clinical trial is a study that helps researchers determine if a new treatment is safe and effective. All medications must go through multiple phases of clinical trials before they can be approved for the public.

Who is the study sponsor?2025-12-02T16:22:09-08:00

Forte Biosciences

Where is this study located?2025-12-02T16:22:18-08:00

You will be assigned to the study site nearest to you. For more information about the study site locations, please complete the screening survey to see if you may qualify.

What are the potential benefits of participating?2025-12-02T16:22:36-08:00

Participating in a clinical trial is a way to help develop alternative treatment options for celiac disease. You will be part of advancing celiac disease research, while receiving study-related medical care at no cost to you.

If I pre-qualify, what happens next?2025-12-02T16:22:45-08:00

If you pre-qualify through the online screening survey and live near a study clinic, you will be invited to schedule a phone call with a study representative to discuss your eligibility and potential participation. If you are interested, you will be contacted by the study clinic to schedule a screening visit. At this visit, you will speak to the study doctor and receive all the information you need to decide if you want to participate.

Can I change my mind about participating once I am enrolled in the study?2025-12-02T16:22:53-08:00

Yes. Your participation is completely voluntary. You can change your mind and withdraw from the study at any time.

Will I be given the study drug or placebo?2025-12-02T16:23:35-08:00

In this study, participants will be randomly assigned (by chance, like flipping a coin) to receive the study drug or placebo. You will have an 80% chance of receiving the study drug and a 20% chance of receiving placebo. To make sure the results are not influenced by anyone, neither you nor the study team will know which group you are in, unless there is an urgent medical need.

How long will my participation in the study last?2025-12-02T16:23:45-08:00

You will be in the study for about 8 months.

Will I have to pay to participate?2025-12-02T16:23:53-08:00

No. All study tests, procedures, and medication will be provided to you at no cost.

Will I be compensated for time and travel?2025-12-02T16:23:59-08:00

Compensation for your time and travel will be available. The study team at your location will provide additional details about this before you agree to participate.

I have additional questions, who can I contact?2025-12-02T16:24:06-08:00
