Study typeTreatment
Scientific titleRenin Angiotensin SyStem blockade: diabetes nephropathy
Study acronymRASS
Study objectivesInhibition of the renin angiotensin system will protect the kidney.
Ethics approval(s)Approval received from the Mount Sinai research ethics board
Health condition(s) or problem(s) studiedDiabetic Nephropathy (DN)
Intervention1. Angiotensin-Converting Enzyme (ACE) inhibitor: Enalapril
2. Angiotensin Receptor Blocker: Losarten
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Enalapril, Losarten
Primary outcome measureThe primary outcome is to determine, in Type one diabetes without clinical evidence of diabetic nephropathy, if inhibition of the renin-angiotensin system activity can prevent or retard the rate of development of the histologic lesions associated with diabetic nephropathy.
Secondary outcome measures1. Retinopathy
2. Microalbuminuria
3. Blood pressure
4. GFR
5. Creatinine
