Condition type 1 diabetes
Treatments statin, ace inhibitor, placebo, combination therapy
Phase phase 3
Sponsor University of Cambridge
Collaborator Juvenile Diabetes Research Foundation
Start date January 2009
End date September 2016
Trial size 500 participants
Trial identifier NCT01581476, 2007-001039-72, RP06


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 Design

Allocation randomized
Endpoint classification efficacy study
Intervention model factorial assignment
Masking double blind (subject, caregiver, investigator)
Primary purpose prevention
(Active Comparator)
Participants receive active statin and placebo ACEI
statin Atorvastatin
10mg daily for a minimum period of 2 years
(Active Comparator)
Participants receive active ACEI and placebo statin
ace inhibitor Quinapril
Starting dose of 5mg daily rising after 14 days to 10mg daily providing it is well tolerated for a minimum period of 2 years.
(Placebo Comparator)
Participants receive placebo ACEI and placebo statin
Participants receive statin placebo and ACEI placebo
Participants receive both active ACEI and active Statin
combination therapy Atorvastatin
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

Male or female participants from 10 years up to 16 years old.

Inclusion Criteria: 1. Age 10 to 16 years. 2. T1D diagnosed for more than 1 year or C-peptide negative. 3. 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. Exclusion Criteria: 1. Non T1D, i.e. type 2 diabetes, insulin dependent diabetes related to monogenic disease, secondary diabetes. 2. ACR based on six early morning urines deemed to be at low risk for subsequent development of CVD or DN. 3. Pregnancy or unwillingness to comply with contraceptive advice and regular pregnancy testing throughout the trial. 4. Breast feeding 5. Severe hyperlipidaemia and family history data to support diagnosis of familial hypercholesterolaemia. 6. Established hypertension unrelated to DN. 7. Prior exposure to the investigational products, statins and ACEI. 8. Unwillingness/inability to comply with the study protocol. 9. Other co-morbidities considered unsuitable by the investigator (excluding treated hypothyroidism and coeliac disease). 10. Proliferative retinopathy. 11. Renal disease not associated with Type 1 Diabetes.
