Novel Therapy to Preserve Beta Cell Function in New Onset Type 1 Diabetes
Stopped early · Phase 2
Conditions studied: Diabetes Mellitus Type 1, Autoimmune Diabetes
In brief
Background: * Type 1 diabetes (T1D) occurs when the immune system attacks insulin-producing cells (beta cells) in the pancreas, resulting in their death. * Insulin injections currently are the best method for controlling blood sugar in individuals with T1D. However, animal studies have shown that the drugs sitagliptin and lansoprazole can help reverse beta cell damage or develop new beta cells. In addition, Diamyd has been shown to weaken the immune process that attacks pancreatic beta cells. Objectives: * To find out whether a combination treatment of sitagliptin, lansoprazole, and Diamyd will help maintain functioning beta cells and/or cause new beta cells to form. * To determine how the drug combination affects insulin doses and blood sugar control. * To determine whether the drug combination affects the immune response involved in T1D.

- Insulin requirements greater than 0.8 units/kg/day at the end of the run-in period
- Regular use of a proton pump inhibitor within 3 months of enrollment

- Use of immunosuppressive therapy in the preceding 12 months
- Evidence of chronic infection, for example, known human immunodeficiency virus (HIV) or hepatitis
- History of any malignancy other than a treated basal or squamous skin cancer
- Any chronic medical condition to unduly increase risk for the potential enrollee as judged by study investigators
- Pregnancy, breastfeeding or planned pregnancy within two years, women of reproductive age not using an effective mode of contraception and unwilling to continue adequate contraception until 1 year after the last study drug administration
- Any other co-existing condition/circumstances that would make patient unsuitable to participate in the study, as deemed by the investigators. For example, study investigators would exclude any potential candidate with any of the following (but the list is not inclusive):
- A. Clinically significant past history of an acute reaction to vaccines or other drugs
- B. Recent participation in other clinical trials with a new chemical entity
- C. A history of alcohol or drug abuse
- D. Significant neurological conditions like epilepsy, head trauma, or cerebrovascular accidents
- E. Individuals with significant gastrointestinal disorders determined by the study investigators to influence either study safety or data interpretation. Such conditions include but are not limited to gastroparesis and gastric bypass surgery
- F. Individuals with conditions prone to hypergastrinemia (Zollinger-Ellison syndrome, use of histamine-2 receptor blockers) or hypogastrinemia (gastric surgery).
