简要总结
- To investigate the dose response of the combination therapy, Telmisartan and Hydrochlorothiazide for the Japanese patients with Essential Hypertension.
- To compare this dose response with that in the US study.
详细描述
This is an 8-week multicentre, randomised, double-blind, double-dummy, placebo-controlled, parallel group study utilizing all cells of a 3 x 3 factorial design. Following Screening examinations and a 4-week Placebo Run-In Period, 540 patients will be randomized to receive once-daily monotherapy with either telmisartan (MICARDIS), hydrochlorothiazide, placebo, or combination therapy with telmisartan and hydrochlorothiazide for 8 weeks (Treatment Period).
This study includes nine cells, placebo, telmisartan (TEL) 40 mg, TEL 80 mg, hydrochlorothiazide (HCTZ) 6.25 mg, HCTZ 12.5 mg, TEL 40 mg/HCTZ 6.25 mg, TEL 40 mg/HCTZ 12.5 mg, TEL 80 mg/HCTZ 6.25 mg, and TEL 80 mg/HCTZ 12.5 mg.
Study Hypothesis:
The hypothesis is that the dose response model for the Japanese patient with essential hypertension which is constructed for the change of the supine diastolic blood pressure from the baseline value to end of treatment with the multiple regression analysis, is similar to that in the US study 502.204.
