Telmisartan/Amlodipine (80/10) vs. Telmisartan/Amlodipine (40/10) vs. amlodipine10 in Resistant Hypertension

Phase 3
Completed
Conditions
Hypertension
Registration Number
NCT00553267
Lead Sponsor
Boehringer Ingelheim
Brief Summary

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.

Inclusion Criteria
  • 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.
Exclusion Criteria
  • 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.
