Summary

Primary Objective:

To demonstrate that the antihypertensive efficacy of the fixed combination irbesartan/amlodipine 300/5 mg is superior to that of irbesartan 300 mg monotherapy in lowering systolic blood pressure (SBP) as measured by home blood pressure measurement (HBPM) after 10 weeks of treatment (W10)

Secondary Objective:

- To compare the antihypertensive efficacy of the fixed combination irbesartan/amlodipine

300/5 mg with that of irbesartan 300 mg monotherapy after 10 weeks of treatment (W10)

- To compare the antihypertensive efficacy of the fixed combination therapy

irbesartan/amlodipine 150/5 mg with that of irbesartan 150 mg monotherapy after 5 weeks of treatment (W5)

- To examine in each treatment group the change from week 5 to week 10 in SBP and

diastolic blood pressure (DBP) assessed by HBPM and by office blood pressure measurement (OBPM)

- To determine the incidence and severity of adverse events

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion criteria:

- Established essential hypertension

- Treated with irbesartan 150 mg monotherapy for at least 4 weeks

performed over the last 6 days of the first period of measurements

- Creatinine clearance = or > 30 ml/min determined ny Cockroft formula

Exclusion criteria:

- Mean SBP = or > 180 mmHg and/or mean DBP = or > 110 mmHg measured at doctor's office

at Visit 1

- Known or suspected causes of secondary hypertension

- Patients with bilateral artery stenosis, renal artery stenosis in a solitary kidney,

renal transplant or only has one functioning kidney

the combination or history of angioedema related to the administration of an angiotensin II receptor antagonist or any combination of the drugs used

- Know type 1 diabetes

- Know severe hepatic impairment alanine aminotransferase (ALT) or aspartate

aminotransferase (AST) > 5 times the upper limit of normal or history of hepatic encephalopathy, esophageal varices, or portocaval shunt

- Know severe renal impairment (creatinine clearance < 30 ml/mn)

- Concomitant use of any other antihypertensive treatment

- Administration of any other investigational drug within 30 days before inclusion

- Inability to obtain a valid automatic BP measurement recording

- Presence of any severe medical or psychological condition that, in the opinion of the

investigator, indicate that participation in the study is not in the best interest of of the patient

- Presence of any other conditions (e. g.: geographical, social, etc) that would

restrict or limit the patient participation for the duration of the study

- Pregnant or breast feeding women

- Women of childbearing potential unable or unwilling to use an acceptable method to

avoid pregnancy for the entire study period
