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.

Study Arms (4)
Statin
ACTIVE COMPARATORParticipants receive active statin and placebo ACE Inhibitor
Angiotensin-converting enzyme inhibitor
ACTIVE COMPARATORParticipants receive active ACE Inhibitor and placebo statin
Placebo
PLACEBO COMPARATORParticipants receive placebo ACE Inhibitor and placebo statin
Combination therapy
OTHERParticipants receive both active ACE Inhibitor and active Statin
Interventions
Starting dose of 5mg daily rising after 14 days to 10mg daily providing it is well tolerated for a minimum period of 2 years.
Participants receive both active statin and active ACEI. Dose for Statins is 10mg daily. Dosing for ACEI starts at 5mg daily rising to 10mg after 14 days providing it is well tolerated. Both interventions last for a minimum of 2 years.
Eligibility Criteria
You may qualify if:
- Age 10 to 16 years.
- T1D diagnosed for more than 1 year or C-peptide negative.
- Centralised assessment of ACR based on six early morning urines deemed to be in upper tertile for risk after adjustment for age, gender, age at diagnosis and duration of disease.
You may not qualify if:
- Non T1D, i.e. type 2 diabetes, insulin dependent diabetes related to monogenic disease, secondary diabetes.
- ACR based on six early morning urines deemed to be at low risk for subsequent development of CVD or DN.
- Pregnancy or unwillingness to comply with contraceptive advice and regular pregnancy testing throughout the trial.
- Breast feeding
- Severe hyperlipidaemia and family history data to support diagnosis of familial hypercholesterolaemia.
- Established hypertension unrelated to DN.
- Prior exposure to the investigational products, statins and ACEI.
- Unwillingness/inability to comply with the study protocol.
- Other co-morbidities considered unsuitable by the investigator (excluding treated hypothyroidism and coeliac disease).
- Proliferative retinopathy.
- Renal disease not associated with Type 1 Diabetes.
