Outcome Measures

Primary Outcomes (1)

  • Absolute Change From Baseline in Celiac Disease Patient-Reported Outcome Abdominal Symptoms Domain Score Through Week 24

    The CeD PRO questionnaire was captured daily in the eDiary. The questionnaire included 9 items: abdominal cramping, abdominal pain, bloating, gas, diarrhea, loose stool, nausea, headache and tiredness. Participants were asked to rate their symptom severity on an 11-point scale and scores range from 0 (not experiencing the symptom) to 10 (the worst possible symptom experience). Abdominal Symptoms domain included abdominal cramping, abdominal pain, bloating and gas. Total score for abdominal symptoms domain range from 0 to 40. Higher scores indicated worse outcome. Baseline abdominal symptoms domain score was defined as the average of the daily scores for the last week of the placebo run-in period.

    Baseline (average of Day -7 to Day -1) up to Week 24

Secondary Outcomes (10)

  • Absolute Change From Baseline in Celiac Disease Patient-Reported Outcome Diarrhea and Loose Stool Domain Score Through Week 24

    Baseline (average of Day -7 to Day -1) up to Week 24

  • Absolute Change From Baseline in Celiac Disease Patient-Reported Outcome Total Gastrointestinal (GI) Score Through Week 24

    Baseline (average of Day -7 to Day -1) up to Week 24

  • Absolute Change From Baseline in Intraepithelial Lymphocyte (IEL) Density at Week 24

    Baseline to Week 24

  • Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Treatment-Emergent Serious Adverse Events (SAEs) and Treatment-Emergent Adverse Events of Special Interest (AESIs)

    From first dose of study drug administration (Day 1) up to 28 days after the last dose administration, 197 days

  • Number of Participants With Potentially Clinically Important Changes in Hematology

    From first dose of study drug administration (Day 1) up to 28 days after the last dose administration, 197 days

  • +5 more secondary outcomes

You may qualify if:

  • A diagnosis of celiac disease by intestinal biopsy
  • Following a GFD for at least 12 consecutive months
  • Must have detectable (above the lower limit of detection) serum celiac-related antibodies
  • Must have human leukocyte antigen DQ (HLA-DQ) typing consistent with celiac disease (DQ2 and/or DQ8)
  • Subjects must have had at least one of the following symptoms at least once per week during the month before screening: diarrhea, loose stools, abdominal pain, abdominal cramping, bloating, or gas.
  • Body weight between 35 and 120 kg

You may not qualify if:

  • Current diagnosis of any severe complication of celiac disease, such as refractory celiac disease type 1 (RCD-I) or RCD-II, enteropathy-associated T-cell lymphoma (EATL), ulcerative jejunitis, or gastrointestinal (GI) perforation
  • Diagnosis of any chronic, active GI disease other than celiac disease
  • Presence of any active infection
  • Selective immunoglobulin A (IgA) deficiency, defined as having undetectable levels of IgA
  • Known or suspected exposure to coronavirus disease 2019 (COVID-19) infection in the 4 weeks before screening
  • Administration of a live vaccine within 14 days prior to randomization and the first administration of study drug
  • History or presence of any clinically significant disease that, in the opinion of the Investigator, may confound the subject's participation and follow-up in the clinical trial or put the subject at unnecessary risk
  • Females who are pregnant or planning to become pregnant during the study period, or who are currently breastfeeding
