Primary Outcome Measures:
  • Change in Mean Sitting Diastolic Blood Pressure (msDBP) During the Core Phase of the Study [ Time Frame: Baseline Phase 2 (Week 4) to end of Phase 2 (Week 8) ] [ Designated as safety issue: No ]
    The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. A calibrated sphygmomanometer and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, systolic/diastolic blood pressure were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements. A negative change indicates improvement.

  • Change in Mean Sitting Diastolic Blood Pressure (msDBP) During the Extension Phase of the Study [ Time Frame: Baseline Phase 3 (Week 8) to end of Phase 3 (Week 12) ] [ Designated as safety issue: No ]
    The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. A calibrated sphygmomanometer and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, systolic/diastolic blood pressure were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements. A negative change indicates improvement.


Secondary Outcome Measures:
  • Change in Mean Sitting Systolic Blood Pressure (msSBP) During the Core Phase of the Study [ Time Frame: Baseline Phase 2 (Week 4) to end of Phase 2 (Week 8) ] [ Designated as safety issue: No ]
    The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. A calibrated sphygmomanometer and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, systolic/diastolic blood pressure were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements. A negative change indicates improvement.

  • Change in Sitting Pulse Pressure During the Core Phase of the Study [ Time Frame: Baseline Phase 2 (Week 4) to end of Phase 2 (Week 8) ] [ Designated as safety issue: No ]
    Pulse pressure is systolic pressure (SP) minus diastolic pressure (DP). The arm in which the highest sitting DPs were found at study entry was the arm used for all subsequent readings. A calibrated sphygmomanometer and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, SP and DP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements. A negative change indicates improvement.

  • Change in Sitting Pulse Rate During the Core Phase of the Study [ Time Frame: Baseline Phase 2 (Week 4) to end of Phase 2 (Week 8) ] [ Designated as safety issue: No ]
    Pulse rate was measured once for 30 seconds just prior to blood pressure measurements in the sitting position.

  • Percentage of Patients Who Achieved Normalized Blood Pressure During the Core Phase of the Study [ Time Frame: Baseline Phase 2 (Week 4) to end of Phase 2 (Week 8) ] [ Designated as safety issue: No ]
    Normalized Blood Pressure was defined as a msSBP < 140 mmHg and/or a msDBP < 90 mmHg.

  • Percentage of Patients Who Achieved a Protocol-defined Blood Pressure Response During the Core Phase of the Study [ Time Frame: Baseline of Phase 2 (Week 4) to end of Phase 2 (Week 8) ] [ Designated as safety issue: No ]
    Blood pressure response was defined as msSBP < 140 mmHg or a 20 mmHg decrease in msSBP at the end of Phase 2 (Week 8) compared to Baseline in Phase 2 (week 4) or a msDBP < 90 mmHg or a 10 mmHg decrease in msDBP at the end of Phase 2 compared to Baseline in Phase 2.

  • Change in Mean Sitting Systolic Blood Pressure (msSBP) During the Extension Phase of the Study [ Time Frame: Baseline Phase 3 (Week 8) to end of Phase 3 (Week 12) ] [ Designated as safety issue: No ]
    The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. A calibrated sphygmomanometer and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, systolic/diastolic blood pressure were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements. A negative change indicates improvement.

  • Change in Sitting Pulse Pressure During the Extension Phase of the Study [ Time Frame: Baseline Phase 3 (Week 8) to end of Phase 3 (Week 12) ] [ Designated as safety issue: No ]
    Pulse pressure is systolic pressure (SP) minus diastolic pressure (DP). The arm in which the highest sitting DPs were found at study entry was the arm used for all subsequent readings. A calibrated sphygmomanometer and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart.

A negative change indicates improvement.

  • Change in Sitting Pulse Rate During the Extension Phase of the Study [ Time Frame: Baseline Phase 3 (Week 8) to end of Phase 3 (week 12) ] [ Designated as safety issue: No ]
    Pulse rate was measured once for 30 seconds just prior to blood pressure measurements in the sitting position.

  • Percentage of Patients Who Achieved Normalized Blood Pressure During the Extension Phase of the Study [ Time Frame: Baseline Phase 3 (Week 8) to end of Phase 3 (Week 12) ] [ Designated as safety issue: No ]
    Normalized Blood Pressure was defined as a msSBP < 140 mmHg and/or a msDBP < 90 mmHg.

  • Percentage of Patients Who Achieved a Protocol-defined Blood Pressure Response During the Extension Phase of the Study [ Time Frame: Baseline of Phase 3 (Week 8) to end of Phase 3 (Week 12) ] [ Designated as safety issue: No ]
    Blood pressure response was defined as msSBP < 140 mmHg or a 20 mmHg decrease in msSBP at the end of Phase 3 compared to Baseline in Phase 3 or a msDBP < 90 mmHg or a 10 mmHg decrease in msDBP at the end of Phase 3 compared to Baseline in Phase 3.
