The primary objective of this trial is to demonstrate that the fixed dose combination of telmisartan 40mg + amlodipine 10mg (T40/A10) or the fixed dose combination of telmisartan 80mg + amlodipine 10mg (T80/A10) is superior in reducing blood pressure at eight weeks compared with amlodipine 10mg monotherapy (A10) in patients who fail to respond to six weeks treatment with A10.
Drug: fixed dose combination of telmisartan+amlodipine
||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Primary Purpose: Treatment
||An Eight-week Randomised, Double-blind Study to Compare the Fixed-dose Combination of Telmisartan 40mg + Amlodipine 10mg Versus Telmisartan 80mg + Amlodipine 10mg Versus Amlodipine 10mg Monotherapy in Patients With Hypertension Who Fail to Respond Adequately to Treatment With Amlodipine 10mg Monotherapy
Primary Outcome Measures:

|Ages Eligible for Study:
||18 Years and older
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- diagnosis of essential hypertension and blood pressure not adequately controlled before informed consent (inadequate control defined as seated diastolic blood pressure (DBP) >= 95 mmHg if on existing antihypertensive treatment or seated DBP >= 100 mmHg if treatment-naïve).
- failure to respond to six weeks treatment with amlodipine 10mg. (Failure to respond defined as seated DBP >= 90 mmHg.)
- able to stop any current antihypertensive therapy without unacceptable risk to the patient.
- willing and able to provide written informed consent.
- pregnancy, breast-feeding, unwilling to use effective contraception (if female of child-bearing potential).
- known or suspected secondary hypertension.
- mean seated systolic blood pressure (SBP) >=200 mmHg and/or mean seated DBP >= 120 mmHg during run-in treatment or mean seated SBP >= 180 mmHg and/or mean seated DBP >= 120 mmHg at the randomisation visit or at any time during randomised treatment.
- any clinically significant hepatic impairment or severe renal impairment bilateral renal artery stenosis or renal artery stenosis in a solitary kidney or post post-renal transplant.
- clinically relevant hyperkalaemia.
- uncorrected volume or sodium depletion.
- primary aldosteronism.
- hereditary fructose or lactose intolerance.
- symptomatic congestive heart failure.
- patients who have previously experienced symptoms characteristic of angioedema during treatment with ACE inhibitors or ARBs.
- history of drug or alcohol dependency within the six months prior to signing consent.
- concurrent participation in another clinical trial or any investigational therapy within thirty days prior to signing consent.
- hypertrophic obstructive cardiomyopathy, hemodynamically relevant stenosis of the aortic or mitral valve.
- known allergic hypersensitivity to any component of the formulations under investigation. (Includes known hypersensitivity to telmisartan or other ARBs or amlodipine or other dihydropyridine CCBs.)
- non-compliance with study medication (defined as less than 80% or more than 120%) during the open-label run-in treatment period.
- current treatment with any antihypertensive agents, whether or not prescribed for this indication, that cannot be safely stopped (investigator¿s decision) by the start of the run-in period.
- chronic administration of any medication known to affect blood pressure, other than the trial medication.
- any other clinical condition which, in the opinion of the investigator, would not allow safe completion of the protocol and safe administration of telmisartan and amlodipine.
