Double-blind, randomized, parallel-group, dose ranging, multi-center study to evaluate the efficacy and safety of 2.5, 10, 35 and 50 mg AVE7688 once daily, using 100 mg losartan-potassium once daily as calibrator, for 12 months treatment, in patients with mild to moderate hypertension - RAVEL-1

Recruitment & Eligibility

Status: ot Recruiting

Sex: All

Target Recruitment: 1730

Inclusion Criteria

Patients, 18 years of age or older, with mild-to-moderate, treated or untreated, essential hypertension, as defined by the JNC VII guidelines, who meet the following BP eligibility criteria:
- At the first qualifying visit in the placebo lead-in phase (either visit P2 or P3), mean SeSBP =140 mm Hg and <180 mm Hg and mean SeDBP =90 mm Hg and <110 mm Hg (mean of at least 3 readings)
- At the second qualifying visit in the placebo lead-in phase (either visit P3 or P4 separated from the first qualifying visit by at least 1 week), SeSBP =140 mm Hg and <180 mm Hg and mean SeDBP =90 mm Hg and <110 mm Hg (mean of at least 3 readings). If the patient does not meet the criteria at the second qualifying visit, he or she will be excluded from randomization.
-The patient can be included in the study only when the variability between the mean BP measurements on the two consecutive qualifying visits (either P2 and P3 or P3 and P4 (if applicable)) is less or equal than 7 mm Hg for SeDBP.

- Known history of secondary hypertension, including patients with endocrine disorders such as pheochromocytoma, active hyperthyroidism, or untreated hypothyroidism
- Severe hypertension, defined as SeSBP =180 mm Hg or SeDBP =110 mm Hg
- Women of child bearing potential (i.e. female patients who are not postmenopausal or surgically sterile), who have a positive serum pregnancy test, or who do not agree to use an accepted method of contraception

- History of stroke, intracranial hemorrhage or transitory ischemic attack within the previous year
- Likelihood of poor compliance both with treatment and study design, including social and geographical reasons
- Patient is the investigator, sub-investigator, research assistant, pharmacist, study coordinator, or other staff member or relative thereof directly involved in the conduct of the study
- Administration of any investigational drug within the preceding 30 days. Investigational drug is defined as any agent (placebo or active drug) dispensed as part of a research study
- Abuse of drugs or alcoholic beverages within 1 year prior to the start of the study
- Patients taking herbal or dietary compounds that have the potential to influence blood pressure

Criteria related to ACE-inhibition

- History of hypersensitivity or angioedema with ACE inhibitors or NEP inhibitors, patients with hereditary or idiopathic angioedema, patients with allergic reaction in which urticaria or angioedema was the manifestation
- Impaired hepatic function (i.e., AST and/or ALT >1.5 x upper limit of normal range)
- Known unilateral or bilateral renal artery stenosis
- Serum potassium = 5.5 mmol/L
- Impaired renal function (i.e. calculated creatinine clearance < 50 ml/min)
