Descriptive Information
Brief Title  ICMJE Adolescent Type 1 Diabetes Cardio-Renal Intervention Trial
Official Title  ICMJE Randomised, Double Blind, Placebo Controlled Trial of Angiotensin Converting Enzyme Inhibitors and Statins in the Prevention of Long Term Complications in Young People With Type 1 Diabetes
Brief Summary The purpose of this study is to determine whether use of blood pressure lowering drugs, Angiotensin converting enzyme inhibitors (ACEIs) and blood fat (lipid) lowering drugs (statins) may have a place in the treatment of adolescents with diabetes and can help reduce serious long-term health problems in this population.
Detailed Description

Subjects will be recruited from a pre-screened population of 3,000 young people with T1D aged 10 to 16 years based on assessment of risk for future CVD and DN.

They will be randomised to a 2 x 2 factorial design contrasting the effects of ACEI, statins, or combination therapy to placebo over a maximum four year treatment period. Minimisation of variation in albumin excretion rate, gender, age, diabetes duration, HbA1c, total cholesterol and centre site will be undertaken at randomisation.

Analysis of the primary endpoint, change in albumin excretion will be undertaken on an intention to treat basis. Secondary analyses will be undertaken on the basis of 'as treated' allowing for variance in compliance and allowing for subjects who show substantial change in HbA1c levels. Additional analyses will be undertaken to assess changes in the secondary objectives and to assess the overall effect of the intervention on quality of life and health economics.
