简要总结
This study is a multicenter, randomized, double-masked, placebo-controlled clinical study. All groups will receive standard intensive diabetes treatment with insulin and life style management. 60 subjects will be randomly assigned in a 1:1:1 ratio to receive placebo or different dosage of GABA.
GABA is an amino acid produced from glutamate by glutamic acid decarboxylase. It was approved for the treatment of hepatic coma, fibromyalgia, ataxia in China and is widely used as supplement for the treatment of epilepsy, insomnia, stress and tobacco dependence. It has been recently shown that GABA can prevent and reverse the development of diabetes in type 1 mice models. Participants will receive placebo or GABA for 52 weeks.
The study will consist of 4 weeks screening period, 2 weeks run-in period, 52 weeks treatment period and 4 weeks follow-up period. Enrollment is expected to occur over 2 years.
To assess the efficacy and safety of GABA for the treatment of juvenile type 1 diabetes in new onset subjects.
详细描述
Primary Outcome:
The primary statistical hypothesis to be assessed in this study is whether the mean C-peptide value for study subjects receiving GABA differs significantly from the mean value for placebo subjects assessed at follow-up.
Secondary Outcome:
The study will examine the HbA1C and the daily dosage of insulin (units/kg).
