|Condition or disease||Intervention/treatment||Phase|
|Hypertension||Drug: telmisartan 80 mg + hydrochlorothiazide 25 mg||Phase 3|
Patients with a history of hypertension who completed a preceding trial (number 502.480) within the previous fourteen (14) days will be considered for entry to this long-term open-label trial. All patients will receive 'T80/H25'. Additional antihypertensive therapy will be allowed if the patients' blood pressure is not well controlled. [In the preceding double-blind trial 502.480, patients who failed to respond to the fixed dose combination of telmisartan 80 mg '+' hydrochlorothiazide 12.5 mg (T80/H12.5) were randomised to 'T80/H12.5' or T80H25 for eight weeks.] This is a multi-centre, multinational trial with approximately 80 study centres participating. Only study centres participating in the preceding trial 502.480 can enter patients into this open-label trial. It is anticipated that a maximum of 480 patients will be entered into the trial in seventeen countries. Each trial centre is expected to enter between four and twenty-four patients.
Enrollment of patients into this trial will finish when the last patient completes the preceding trial 502.480. At this time, centres will be notified of the termination of recruitment and will not be authorized to include any further patients.
Patients will visit the clinic one month, three months and six months later for assessment of their blood pressure and general health. Their participation in the study is complete six months after the start of the treatment period.
No statistical hypothesis will be tested. Descriptive statistics will be used to characterise the effects of treatment with T80/H25 with and without other antihypertensive treatments.
The proportion of patients achieving DBP control will be summarised by the total number of patients in the trial as well as by the maximum achieved dose level according to the two categories of T80/H25 alone (T80/H25) and with other antihypertensive medication added (T80/H25/other). An additional sub-group summary by the treatment group in the preceding trial 502.480 (T80/H12.5 and T80/H25) will also be presented.
