Further study details as provided by Alba Therapeutics:

Primary Outcome Measures:
  • To demonstrate the safety and tolerance of single, oral doses of AT-1001 in celiac disease subjects that are gluten-free and in remission
  • To determine whether quantifiable AT-1001 concentrations are present in plasma following single oral doses and to characterize the pharmacokinetic behavior of AT-1001 in celiac disease subjects that are gluten-free and in remission
  • To evaluate the effects of single doses of AT-1001 on intestinal permeability ratios and zonulin levels following single, oral challenge doses of gluten (2.5 gm) by utilizing urinary lactulose and mannitol, and serum zonulin concentrations as biomarkers.

Secondary Outcome Measures:
  • Self-reported measures of GI discomfort
  • Pharmacokinetic Measures
  • Pharmacodynamic Measures

Estimated Enrollment: 24
Study Start Date: January 2006
Estimated Study Completion Date: February 2006
Detailed Description:

One (1) cohort of 24 (2:1 drug:placebo) subjects will receive single oral doses of either AT-1001 or matching placebo. Subjects will complete screening and thereafter be admitted to the clinic prior to treatment. On Day 1 AT-1001 or matching placebo will be administered followed by a baseline intestinal permeability test. Intestinal permeability will be measured by administration of an oral sucrose, lactulose and mannitol solution followed by an 8-hour urine collection. Day 2 subjects will be given AT-1001 or matching placebo followed by a gluten challenge and have the intestinal permeability test repeated. Day 3 subjects will be administered AT-1001 or matching placebo followed by a post gluten challenge intestinal permeability test. Serial blood samples will be collected for pharmacokinetic determinations at baseline, 2, and 3 hours post administration of AT-1001 or matching placebo, for zonulin determinations at baseline (prior to first dose) and at 3 hours post dose, and for cytokine determination at baseline, 3 hours post dose (Days 2 and 3 only) and Day 7. Sucrose, lactulose, mannitol, zonulin and AT-1001 concentrations will be determined by validated analytical methods.

Subjects will be evaluated at screening (medical history, physical examination, vital signs, clinical laboratory testing, and 12-lead electrocardiogram). Vital signs and clinical laboratory testing will be conducted pre-dose and vital signs, clinical laboratory testing and EKG will be monitored post dose. Adverse event reports will be monitored throughout the study. At the end of the study a physical exam and clinical laboratory testing will be performed.
