Purpose

The study objective is to compare the effects of single and multiple doses of the oral direct renin inhibitor aliskiren and the angiotensin receptor antagonist irbesartan on renal blood flow, glomerular filtration rate, and retinal blood flow in patients with type 2 diabetes mellitus.

Further study details as provided by Novartis:

Primary Outcome Measures:

Renal blood flow and glomerular filtration rate at baseline, after 1 and 14 days of treatment with aliskiren or irbesartan and after a single dose of captopril (an angiotensin converting enzyme inhibitor and positive control) [ Time Frame: 1 and 14 days of treament ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Retinal blood flow at baseline, after 14 days of treatment with aliskiren or irbesartan, after a singe dose of captopril Plasma levels of renin system biomarkers (renin, pro-renin, angiotensin 1, angiotensin 2, angiotensinogen, and aldosterone) [ Time Frame: 14 days of treatment ] [ Designated as safety issue: No ]

Enrollment:	45
Study Start Date:	April 2008
