Evaluation of Safety and Diabetes Status Upon Oral Treatment With GABA in Patients With Longstanding Type-1 Diabetes

Summary

The main goal of this study is to find a reasonably safe and tolerable treatment for adult patients with type 1-diabetes and that regain some of the endogenous insulin secretion, improve the patients' quality of life (QoL) and reduce the risk of both short- and long-term complications. The hypothesis tested is that oral GABA treatment with the newly developed compound Remygen will be safe and induce regain of some endogenous insulin secretion in adult patients with type 1-diabetes diagnosis for more than five years. The first part of the study will include 6 patients and be performed as a Safety and Dose Escalation study in three steps. The main study is a three-arm, open label, single center, clinical trial. Eligible patients will be randomized into one of three active treatment arms to receive oral GABA treatment for 6 months.

Conditions

• Type 1 Diabetes Mellitus

Interventions

Type	Name	Description
DRUG	Gamma-Aminobutyric Acid (GABA)	Patients eligible for the main study will be randomized in a 1:1:1 ratio stratified by the C-peptide level to receive 200 mg of GABA (Remygen) for 6 months, 600 mg of GABA (Remygen) for 6 months, or Alprazolam 0.5 mg combined with GABA 600 mg (Remygen) for 3 months followed by treatment with GABA 600 mg (Remygen) only for another 3 months. The start of the arms with high dose GABA will be delayed and started first after that a data safety monitoring board has evaluated and approved the safety data of the first 4 patients included in the arm with low dose GABA. All patients will continue to receive intensive insulin treatment from their personal physicians during the whole study period.
