Primary Outcome Measures:

Change From Baseline in Mean Ambulatory Diastolic Blood Pressure (DBP) in the Last 4 Hours After 12-week Treatment [ Time Frame: Baseline and Week 12 ]
Ambulatory blood pressure monitoring (ABPM) determined blood pressure 3 times hourly in the daytime and once hourly in the nighttime. Only monitoring data with valid data greater than or equal to (>=) 80 percent (%) was used for analysis. Each ABPM lasted for at least 24 hours. The first dynamic blood pressure monitoring was used as baseline. The difference between the mean ambulatory DBP observed in the last 4 hours after 12-week treatment and baseline was calculated to find out the change of mean ambulatory DBP at the end of the treatment.
Change From Baseline in Mean Heart Rate in the Last 4 Hours After 12-week Treatment [ Time Frame: Baseline and Week 12 ]
Pulse rate was measured by palpation on radial artery for 1 minute. Two measurements were made at least 1 to 2 minutes apart. Finally mean heart rate was recorded. The first measured heart rate was used as baseline heart rate. The difference between the last 4 hours heart rate after 12-week treatment and of the baseline heart rate was calculated to measure the change in mean heart rate at the end of the treatment.

Secondary Outcome Measures:

Change From Baseline in Mean Ambulatory Systolic Blood Pressure (SBP) in the Last 4 Hours After 12-week Treatment [ Time Frame: Baseline and Week 12 ]
The ABPM determined blood pressure 3 times hourly in the daytime and once hourly in the nighttime. Only monitoring data with valid data >=80% was used for analysis. Each ABPM lasted for at least 24 hours. The first dynamic blood pressure monitoring was used as baseline. The difference between the mean ambulatory SBP observed in the last 4 hours after 12-week treatment and baseline was calculated to find out the change of mean ambulatory SBP at the end of the treatment.
Change From Baseline in Mean Ambulatory 24-hour Blood Pressure at Week 12 [ Time Frame: Baseline and Week 12 ]
The ABPM determined blood pressure 3 times hourly in the daytime and once hourly in the nighttime. Only monitoring data with valid data >=80% was used for analysis. Each ABPM lasted for at least 24 hours. The first dynamic blood pressure monitoring was used as baseline. The difference between the mean ABPM observed in the last 24 hours at Week 12 and baseline was calculated to find out the change of mean ABPM at the end of the treatment.
Change From Baseline in Mean Ambulatory Daytime Blood Pressure at Week 12 [ Time Frame: Baseline and Week 12 ]
The ABPM determined blood pressure 3 times hourly in the daytime. Only monitoring data with valid data >=80% was used for analysis. Each ABPM lasted for at least 24 hours. The first dynamic daytime blood pressure monitoring was used as baseline. The difference between the mean ambulatory daytime blood pressure observed at Week 12 and baseline was calculated to find out the change of mean ambulatory daytime blood pressure at the end of the treatment. Daytime in this study was defined as time between 06:00 am to 10:00 pm.
Change From Baseline in Mean Ambulatory Night-time Blood Pressure at Week 12 [ Time Frame: Baseline and Week 12 ]
The ABPM determined blood pressure once hourly in the nighttime. Only monitoring data with valid data >=80% was used for analysis. Each ABPM lasted for at least 24 hours. The first nighttime blood pressure monitoring was used as baseline. The difference between the mean ambulatory nighttime blood pressure observed at Week 12 and baseline was calculated to find out the change of mean ambulatory nighttime blood pressure at the end of the treatment. Nighttime in this study was defined as 10:00 pm to 06:00 am.
Change From Baseline in Mean Ambulatory Daytime Heart Rate at Week 12 [ Time Frame: Baseline and Week 12 ]
Pulse rate was measured by palpation on radial artery for 1 minute. Two measurements were made at least 1 to 2 minutes apart. Finally mean heart rate was recorded. The first measured daytime heart rate was used as baseline heart rate. The difference between the daytime heart rate at Week 12 treatment and of the baseline heart rate was calculated to measure the change of mean ambulatory daytime heart rate at the end of the treatment. Daytime in this study was defined as 06:00 am to 10:00 pm.
Change From Baseline in Mean Ambulatory Night-time Heart Rate at Week 12 [ Time Frame: Baseline and Week 12 ]
Pulse rate was measured by palpation on radial artery for 1 minute. Two measurements were made at least 1 to 2 minutes apart. Finally mean heart rate was recorded. The first measured heart rate was used as baseline heart rate. The difference between the nighttime heart rate at Week 12 treatment and of the baseline heart rate was calculated to measure the change of mean ambulatory nighttime heart rate at the end of the treatment. Nighttime was defined as 10:00 pm to 06:00 am.
Change From Baseline in 24-hour Blood Pressure Variability at Week 12 [ Time Frame: Baseline and Week 12 ]
The ABPM determined blood pressure 3 times hourly in the daytime and once hourly in the nighttime. Only monitoring data with valid data >=80% was used for analysis. Each ABPM lasted for at least 24 hours. The first dynamic blood pressure monitoring was used as baseline. The mean change in the blood pressure variability between the 24-hour blood pressure observed at Week 12 and baseline was calculated.
Blood Pressure Response Rate [ Time Frame: Week 12 ]
Blood pressure response was defined as DBP less than or equal to (=<) 90 mmHg or >=10 mmHg decrease in DBP from baseline. Blood pressure response rate was calculated as: number of subjects with blood pressure response divided by total number of subjects and multiplied by 100.
Heart Rate Response Rate [ Time Frame: Week 12 ]
Heart rate response was defined as decrease in heart rate from baseline >=10 percent (%). Heart rate response rate was calculated by using the number of subjects with heart rate response divided by total number of subjects and multiplied by 100.
Change From Baseline in Mean Ambulatory 24-hour Heart Rate at Week 12 [ Time Frame: Baseline and Week 12 ]
Pulse rate was measured by palpation on radial artery for 1 minute. Two measurements were made at least 1 to 2 minutes apart. Finally mean heart rate was recorded. The first measured heart rate was used as baseline heart rate. The difference between the last 24 hours heart rate at Week 12 and of the baseline heart rate was calculated.
