Brief summary
The objective of this study is to compare the efficacy and safety of combined administration of TAK-536CCB (Fix-dose combination of Azilsartan and Amlodipine) and Hydrochlorothiazide (HCTZ) with those of TAK-536CCB in patients with Grade I or II essential hypertension.
Detailed description
This study is a randomized, double-blind, multicenter, phase 2/3 study to evaluate the efficacy and safety of combined administration of TAK-536CCB and Hydrochlorothiazide (HCTZ) with those of TAK-536CCB or Hydrochlorothiazide in patients with grade I or II essential hypertension. This study consists of a 4-week single-blind placebo run-in period and a 10-week double-blind treatment period.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in the office trough sitting diastolic blood pressure (DBP) | Baseline and Week 10 | Change in the office trough sitting DBP from the end of the placebo run-in period (baseline \[Week 0\]) to the end of the treatment period (Week 10, last observation carried forward \[LOCF\]) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of patients achieving < 140/90 mmHg | 10 weeks | Patients achieving \< 140/90 mmHg refer to those meeting both of the following criteria: * A decrease to \< 90 mmHg in office trough sitting DBP * A decrease to \< 140 mmHg in office trough sitting SBP |
| Proportion of responders (140/90 mmHg criterion) | 10 weeks | Patients who met either of the following conditions are regarded as responders (140/90 mmHg criterion). * A ≥ 20 mmHg decrease in office trough sitting SBP and a ≥ 10 mmHg decrease in the office trough sitting DBP * A decrease to \< 140 mmHg in office trough sitting SBP and a decrease to \< 90 mmHg in office trough sitting DBP |
| Change from Baseline in the office trough sitting systolic blood pressure (SBP) | Baseline and Week 10 | Change in the office trough sitting SBP from the end of the placebo run-in period (baseline \[Week 0\]) to the end of the treatment period (Week 10, last observation carried forward \[LOCF\]) |
