Brief summary
The purpose of this study is to compare the different dose of DMTA07 (DM) combine with amlodipine in the treatment of mild to moderate essential hypertension, and to define the optimized dose of DM in the combination therapy.
Detailed description
To compare the different dose of DM combine with amlodipine in the treatment of mild to moderate essential hypertension, and to define the optimized dose of DM in the combination therapy. The purpose of this study is to compare the antihypertensive efficacy and tolerability of different dose of DM combines with amlodipine treatment, further to explore the optimized combination dose of DM.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| *SBP reduction=SBP each visit- SBPvisit2 | 14 weeks | The primary objective of this study is to compare the sitting systolic blood pressure (mmHg) reduction\* between four dose regimens, the baseline is defined as the actual SBP value after 2 weeks of amlodipine run-in period |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The secondary objectives of the study include: Efficacy/Safety | 14 weeks | Efficacy: To compare the sitting diastolic blood pressure (mmHg) reduction\* between four dose regimens, the baseline is defined as the actual DBP value after 2 weeks of amlodipine run-in period To evaluate the percentage of SBP reduction in four treatment regimens To evaluate the changes of blood pressure (mmHg) in different clusters; such as diabetes etc. Safety: To evaluate the pulse rate changes To evaluate incidences of adverse events To evaluate the change of laboratory test results from baseline |
