Placebo Comparator

Arm Label

aliskiren 300 mg once daily for 12 weeks

Outcomes

Primary Outcome Measures

Change in Flow-mediated Dilation
Flow-mediated dilation of the brachial artery assessed by ultrasound to evaluate improvement of arterial functioning by % of dilation after non-invasive occlusion

Secondary Outcome Measures

Mean Central Aortic Pressure at 3 Months
Baseline to 3 months after Aliskiren/PLC, reported value at 3 months after start of study of central aortic pressure assessed by non-invasive applanation tonometry ( SphygmoCor, Atcor)

5. Study Description

Brief Summary
The study will evaluate the effects of the direct renin inhibitor, aliskiren, on flow-mediated dilation of the brachial artery and on central aortic pressure in diabetic patients with pre-hypertension or Stage 1 hypertension.
Detailed Description
Patients are double-blind placebo-controlled randomized to either aliskiren or sugar pill/placebo. Effects on blood parameters and arteries are evaluated in both groups.
