Design outcomes

Primary

MeasureTime frame
Main Objective: To compare the change in albumin excretion rate (AER) measured in overnight urine collections from baseline to Week 20 between groups assigned to ramipril and irbesartan or to ramipril and placebo in hypertensive subjects with increased cardiovascular (CV) risk.;Secondary Objective: 1) To estimate the reduction from baseline in seated systolic and diastolic blood pressures at Week 20 within each of the treatment groups. 2) To compare the change from baseline in seated systolic and diastolic blood pressures at Week 20 between treatment groups. 3) To characterize the saftey profiles of each of the two treatment groups.;Primary end point(s): The primary efficacy outcome measure will be defined as the change in AER from baseline to Week 20. Secondary efficacy measures will be the change from baseline in seated systolic and diastolic blood pressures at Week 20.
