Brief summary: This is a study in diabetic patients with at least one additional cardiovascular risk factor and normoalbuminuria prior to randomization.


Eligibility criteria: Inclusion Criteria:

* Diabetes mellitus type 2, defined as fasting blood glucose of greater than or equal to 126 mg/dL;
* Presence of at least one of the following cardiovascular risk factors:

  1. total cholesterol greater than 200 mg/dL or statin treatment,
  2. High density lipoprotein (HDL) less than 40 mg/dL,
  3. triglycerides greater than 150 mg/dL and less than 400 mg/dL,
  4. blood pressure greater than or equal to 130/80 mmHg,
  5. Body mass index (BMI) greater than 28 kg/m2,
  6. waist circumference greater than 102 cm for men and greater than 88 cm for women,
  7. smoking of more than 5 cigarettes a day;
* Normoalbuminuria at screening

Exclusion Criteria:

* Severe uncontrolled hyperlipidemia;
* Documented renal and/or renal-vascular disease;
* Myocardial infarction, stroke or myocardial revascularization within the last 6 months;
* History of alcohol and/or drug abuse;
* Allergic reaction, lack of response or contraindication to angiotensin receptor blockers (ARBs);
* Current treatment with an ARB or angiotensin converting enzyme (ACE) inhibitor

timeFrame: Time to occurrence
measure: Occurrence and progression of retinopathy
timeFrame: Time to occurence
measure: Treatment effects on a combined endpoint of cardiovascular mortality and morbidity and renal disease
