  Purpose

The primary objective of this trial is to assess the efficacy and safety of the fixed dose combinations telmisartan 40mg/amlodipine 10mg (T40/A10) or telmisartan 80mg/amlodipine 10mg (T80/A10) during open-label treatment for at least six months.

An additional objective is to assess the efficacy and safety of concomitant administration of either T40/A10 or T80/A10 with any other therapies commonly used in the treatment of hypertension.

The primary endpoint is the proportion of patients achieving DBP control (defined as mean seated DBP < 90 mmHg at trough i.e. approximately 24 hours after last dose of study treatment) at six months of treatment or at last trough observation during the treatment period (i.e. last trough observation carried forward).


Condition Intervention Phase
Hypertension Drug: fixed-dose combination of telmisartan 40mg+amlodipine 10mg Drug: fixed-dose combination of telmisartan 80mg+amlodipine10mg Phase 3

Study Type: Interventional
Study Design: Primary Purpose: Treatment
Official Title: An Open Label Trial of the Efficacy and Safety of Chronic Administration of the Fixed Dose Combination of Telmisartan 40mg + Amlodipine 10mg or Fixed Dose Combination of Telmisartan 80mg + Amlodipine 10mg Tablets Alone or in Combination With Other Antihypertensive Medications in Patients With Hypertension

Primary Outcome Measures:
  • Trough Seated Diastolic Blood Pressure (DBP) Control [ Time Frame: End of study (34 weeks or last value on treatment) ]
    The number of patients who reached the target DBP of <90mmHg


Secondary Outcome Measures:
  • Trough Seated Systolic Blood Pressure (SBP) Control [ Time Frame: End of study (34 weeks or last value on treatment) ]
    The number of patients who reached the target SBP of >=140mmHg

  • Change From Baseline to End of Study in Trough Seated Diastolic Blood Pressure [ Time Frame: Baseline is defined as visit 3 of study NCT00553267 and end of study as 34 weeks or last value on treatment ]
    Change from baseline to the end of study in trough DBP. Baseline is defined as visit 3 of trial 1235.6

  • Change in DBP From Last Available Trough in NCT00553267 to Last Available Trough in NCT00624052 [ Time Frame: Last available trough in NCT00553267 to end of study (34 weeks or last value on treatment) ]
    The difference between the last available troughs represents the additional reduction in DBP in this study

  • Change From Baseline to End of Study in Trough Seated Systolic Blood Pressure [ Time Frame: Baseline is defined as visit 3 of study NCT00553267 and end of study as 34 weeks or last value on treatment ]
    Change from baseline to the end of study in trough SBP. Baseline is defined as visit 3 of trial 1235.6

  • Change in SBP From Last Available Trough in NCT00553267 to Last Available Trough in NCT00624052 [ Time Frame: Last available trough in NCT00624052 to end of study (34 weeks or last value on treatment) ]
    The difference between the last available troughs represents the additional reduction in SBP in this study

  • Trough Seated DBP Response [ Time Frame: End of study (34 weeks or last value on treatment) ]
    The number of patients who reach the target DBP of <90mmHg or had a reduction in DBP >= 10mmHg

  • Trough Seated SBP Response [ Time Frame: End of study (34 weeks or last value on treatment) ]
    The number of patients who reach the target SBP of <140mmHg or had a reduction in SBP >= 15 mmHg

  • Trough BP Normality Classes [ Time Frame: End of study (34 weeks or last value on treatment) ]
    The number of patients who reach predefined BP categories

  • Time to First Additional Antihypertensive [ Time Frame: up to 34 weeks ]
    Time from first intake of medication to first intake of an antihypertensive other than the study drug

  • Number of Patients Requiring Additional Antihypertensive Therapy to Achieve DBP Control [ Time Frame: up to 34 weeks ]
    The number of patients with DBP control (DBP>=90 mmHg). Last trough DBP measurement before taking additional antihypertensive compared to last trough DBP taken on treatment

  • Additional Reduction in DBP by Use of Additional Antihypertensive Therapy [ Time Frame: up to 34 weeks ]
    Difference in trough DBP from last visit before add-on therapy and last visit during NCT00624052

  • Additional Reduction in SBP by Use of Additional Antihypertensive Therapy [ Time Frame: up to 34 weeks ]
    Difference in trough SBP from last visit before add-on therapy and last visit during NCT00624052

  • Trough DBP Control Pre- and Post- Uptitration [ Time Frame: up to 34 weeks ]
    The number of patients with DBP control (DBP<90 mmHg). Last trough DBP measurement before uptitration to telmisartan 80mg and amlodipine 10mg compared to first trough DBP taken after uptitration. Uptitration could be based DBP>90 or investigator opinion.
