Study Description

PRV-015-002b is a Phase 2b, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of 3 dose regimens of PRV-015 in adult patients with NRCD who are on a GFD.

Eligible subjects include male or female adults, 18 to 70 years of age, with a diagnosis of celiac disease and have followed a GFD for at least 12 consecutive months, yet continue to experience symptoms.

Study drug (1 of the 3 doses of PRV-015 or placebo) will be administered in a double-blind fashion, followed by a safety follow-up period.

    Eligibility Criteria

    Ages Eligible for Study 18 Years to 70 Years (Adult, Older Adult)
    Sexes Eligible for Study All
    Accepts Healthy Volunteers No
    Inclusion Criteria
    • 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
    Exclusion Criteria
    • 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
