Summary

This is a multi-centre, randomised, double-blind, active-controlled, parallel-group comparative trial to compare the fixed dose combination (FDC) of telmisartan 80 mg + hydrochlorothiazide 12. 5 mg and amlodipine 5 mg (T80/A5/H12. 5 mg) to telmisartan 80 mg+ hydrochlorothiazide 12. 5 mg (T80/H12. 5 mg) in blood pressure lowering effect at week 8, the end of the double-blind period in essential hypertensive patients who fail to respond adequately to telmisartan 80 mg+ hydrochlorothiazide 12. 5 mg. Patients are assigned to one of the two groups after a 6-week open-label run-in period taking T80/H12. 5 mg. In addition the long-term safety of telmisartan 80 mg+ amlodipine 5 mg+ hydrochlorothiazide 12. 5 mg will be evaluated in a 52-week extension period. In the 52-week open label extension period patients who are assigned to the T80/A5/H12. 5 mg group continue the T80/A5/H12. 5 mg therapy, and patients who are assigned to the T80/ /H12. 5 mg group change to the T80/A5/H12. 5 mg therapy.

Clinical Details

Official title: An Eight-week Randomised Double-blind Study to Compare the Efficacy and Safety of Telmisartan 80 mg and Amlodipine 5 mg and Hydrochlorothiazide 12.5 mg vs. Telmisartan 80 mg and Hydrochlorothiazide 12.5 mg in Patients With Hypertension Who Fail to Respond Adequately to Treatment With Telmisartan 80 mg and Hydrochlorothiazide 12.5 mg, Followed by a 52 Weeks Extension Study to Assess Long Term Safety of Telmisartan 80 mg and Amlodipine 5 mg and Hydrochlorothiazide 12.5 mg

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double-Blind, Primary Purpose: Treatment

Primary outcome: Change from baseline in mean seated diastolic blood pressure (DBP) at trough after 8 weeks of the double-blind period

Secondary outcome:

The number of patients with DBP<90 mmHg and SBP<140 mmHg as seated blood pressure at trough after 8 weeks of the double-blind period

The number of patients with DBP<90 mmHg and SBP<140 mmHg as seated blood pressure at trough after 52weeks of the extension period

Change from baseline in mean seated systolic blood pressure (SBP) at trough after 8 weeks of the double-blind period

Change from baseline in mean seated DBP at trough after 52weeks of the extension period

Change from baseline in mean seated SBP at trough after 52weeks of the extension period

Eligibility

Minimum age: 20 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion criteria: 1.

Able to stop all current antihypertensive drugs (other than study medication) from Visit 1b through the end of the trial without risk to the patient based on the investigator's opinion 3. Age 20 years or older Exclusion criteria: 1. Patients with known or suspected secondary hypertension 2. Patients with clinically relevant cardiac arrhythmia 3.
