NCT01155284
First received: June 3, 2010

  Purpose

Sanford Research/USD proposes to study the combination therapy of oral administration of sitagliptin and lansoprazole versus placebo for the preservation of pancreatic beta cells still present in patients with recent-onset diabetes and possibly regenerating their beta cells, while safely down-regulating the autoimmune response directed against the beta cells.

  Eligibility

Ages Eligible for Study:   11 Years to 45 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Diagnosis of type 1 diabetes, based on American Diabetes Association criteria, recently diagnosed (within the 6 months before Screening) and confirmed by the presence of at least 1 diabetes related autoantibody (either glutamic acid decarboxylase [GAD], insulinoma-associated protein [IA 2], or insulin, the latter measured within 10 days after starting insulin therapy).
  • Male or female aged between 11 and 45 years, inclusive.
  • Able to swallow study capsules.
  • Willing to comply with "intensive diabetes management" as directed by the investigator, with the goal of maintaining blood glucose as close to American Diabetes Association recommendations as possible.
  • Willing to comply with the schedule of study visits and protocol requirements.

Exclusion Criteria:

  • Use of a GLP 1R agonist or DPP 4 inhibitor within 1 month before enrollment.
  • Use of a PPI within 1 month before enrollment.
  • Use of an oral hypoglycemic agent within 1 month before enrollment or use of thiazolidinediones within 3 months before enrollment (although thiazolidinediones may be used <7days before enrollment).
  • Females of childbearing potential who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period.
  • Females who are pregnant or breastfeeding at the time of enrollment.
  • Subjects with any of the following conditions:

    • Renal insufficiency, defined as estimated glomerular filtration rate (GFR) less than 50 mL/min at Screening, calculated using the Modification of Diet in Renal Disease (MDRD) equation.
    • History of a serious hypersensitivity reaction to sitagliptin or lansoprazole, such as anaphylaxis or angioedema.
    • Severe hepatic insufficiency.
    • History of pancreatitis or gallbladder disease
    • Any significant medical condition, which in the opinion of the investigator or medical monitor would interfere with study participation.
