简要总结
The primary objective is to assess the efficacy and safety of the fixed dose combination of telmisartan 80 mg + hydrochlorothiazide 25 mg (T80/H25) alone or in addition to other antihypertensive therapies during open-label, long-term treatment.
详细描述
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.
Study Hypothesis:
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.
