About

Celiac disease (CD) is characterized as an autoimmune disorder whereby gluten (a protein found in wheat, barley, rye, malt) induces an immunological response in genetically susceptible individuals. The prevalence of CD has been estimated to affect 0.5-1% of the population worldwide. Long term sequelae are numerous and include risk of lymphoma, malabsorption leading to weight loss, anemia, multiple vitamin deficiencies, osteoporosis/osteopenia, secondary autoimmunity, etc. (1)

Full description

Adult subjects with CD will be recruited through our clinic. All patients enrolled will have established CD diagnosed > 6 months. All patients will have history of abnormal MARSH score on initial duodenal biopsy at diagnosis and MARSH 0 on repeat biopsy following a gluten free diet (GFD). All patients will also have positive celiac serologies (anti-TTG, anti-gliadin, etc.) at diagnosis, as well as, positive HLA DQ2/DQ8 genetic profile. At enrollment, all patients will have negative celiac serologies, indicative of serologic remission on a gluten free diet. Female subjects of childbearing potential (does not include those with history of tubal ligation/surgical sterilization, hysterectomy and/or oophorectomy) who are sexually active with a non-sterilized male partners agree to routinely use adequate contraception from signing informed consent, during study process and for an additional 18 weeks after the last dose of vedolizumab. A male subject who is non-sterilized and sexually active with a female partner of childbearing potential agrees to use adequate contraception from signing informed consent throughout the duration of the study and for 18 weeks after the last dose.
