Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The type 1 Diabetes (T1D) TrialNet Pathway To Prevention (PTP) Study assesses and recruits at-risk subjects into clinical trials aimed at preventing the development of full blown T1D. Thousands of first and second degree relatives of persons with T1D are screened for autoimmune abnormalities and positive subjects are followed with metabolic and autoantibody tests. The investigators' ancillary study us designed to test whether characterization of the insulin- glucose-glucagon (IGG) interactions in participants in the PTP study can provide new information about the early stages of the disease. When completed, this study will improve the understanding of the pathogenesis of the early stages of T1D and provide new quantitative tools for prediction and evaluation of insulin-glucagon-glucose interactions relevant to individuals at risk for developing T1D, thereby enabling future preventive intervention trials.
