GABA Treatment in Subjects With Type 1 Diabetes

Status Recruiting

Clinical Trial Summary

test if a food supplementation with GABA can improve insulin production capacity in type 1 diabetes patients by turning alfa cells into beta cells in accordance with mice and cell studies.randomised parallel study with placebo as control

Clinical Trial Description

our results indicate that alfa-cells can be regenerated and used to regenerate functional beta-like cells in vivo in type 1 diabetes models. Aiming to eventually apply these findings to type 1 diabetic patients, we initiated multiple screens seeking for compounds inducing alfa-to-beta-cell conversion. Using the mouse as a model, we thereby found that GABA (gamma-aminobutyric acid) could promote a cycle of conversion of alfa-cells into functional beta-like cells,GABA being considered as a non-harmful food supplement, one could envision a trial in type 1 diabetic patients. Indeed, a putative cure for type 1 diabetes may include halting the autoimmune insult to the pancreatic beta-cells and restoring insulin secretion by expanding beta-cell mass by beta-cell-regeneration and/or preventing beta-cell apoptosis induced by cytokines. Immunosuppression initiated at the onset of type 1 diabetes has been shown to preserve beta-cell function, but is associated with significant toxicities. Other studies using nicotinamide and parenteral insulin have failed to prevent development of type 1 diabetes.

Objectives Primary objective: To investigate the effect and safety of the dietary supplement GABA provided at a dose of 6 g daily compared to placebo for 12 weeks on change in beta-cell function in patients with C-peptide negative type 1 diabetes as an adjunctive therapy to insulin treatment.

Population A total of 30 patients with C-peptide negative type 1 diabetes, randomised 2:1 GABA: Placebo.

Intervention After randomisation patients are treated with the dietary supplement GABA or matching placebo, titrated to 3 x 2g, or maximum tolerated dose, for 12 weeks. The insulin dose is reduced if needed according to Self-monitored blood glucose (SMBG) and hypoglycaemic episodes. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
