Outcome Measures

Primary Outcome Measures :
  1. Mean Blood Pressure Change Systolic Blood Pressure (SBP) From Baseline After 24±2 Weeks of Treatment or at the Last Observation in Case of Early Withdrawal. [ Time Frame: baseline and 24±2 weeks ]

    The primary endpoint is the mean blood pressure change SBP from baseline after 24±2 weeks of treatment or at the last observation in case of early withdrawal.

    Baseline is defined as data collected on baseline visit.


  2. Mean Blood Pressure Change Diastolic Blood Pressure (DBP) From Baseline After 24±2 Weeks of Treatment or at the Last Observation in Case of Early Withdrawal. [ Time Frame: baseline and 24±2 weeks ]

    The primary endpoint is the mean blood pressure change DBP from baseline after 24±2 weeks of treatment or at the last observation in case of early withdrawal.

    Baseline is defined as data collected on baseline visit.



Secondary Outcome Measures :
  1. Percentage of Patients Achieving Target Blood Pressure SBP/DBP <140/90 mmHg. [ Time Frame: 24±2 weeks ]
    Percentage of patients achieving target blood pressure SBP/DBP <140/90 mmHg is a key secondary endpoint.

  2. Percentage of Patients Achieving DBP Response [ Time Frame: 24±2 weeks ]
    Percentage of patients achieving DBP response (defined as mean seated DBP < 90 mmHg or a drop of ≥ 10 mmHg) is a key secondary endpoint.

  3. Percentage of Patients Achieving SBP Response [ Time Frame: 24±2 weeks ]
    Percentage of patients achieving SBP response (defined as mean seated SBP < 140 mmHg or a drop of ≥ 10 mmHg) is a key secondary endpoint.

  4. Change From Baseline of Quality of Life Assessment Data Measured by World Health Organization Quality of Life (WHOQOL-BREF)- Physical Health Domain [ Time Frame: baseline and 24±2 weeks ]

    WHOQOL-BREF, an abbreviated 26 item version of the WHOQOL-100 was developed to enable a brief but accurate assessment of the quality of life.

    The Korean version of WHOQOL-BREF is valid and reliable in the assessment of quality of life in Koreans. The WHOQOL-BREF is based on the four domain structure (physical health, psychological, social relationships, and environment). It was designed to use 5-point scales for all questions (not at all, a little, moderately, mostly, and completely). The scale goes from 4 to 20 in each domain structure and 0 to 5 in overall score, a low value shows better physical health.


  5. Change From Baseline of Quality of Life Assessment Data Measured by World Health Organization Quality of Life (WHOQOL-BREF)- Psychological Domain [ Time Frame: baseline and 24±2 weeks ]

    WHOQOL-BREF, an abbreviated 26 item version of the WHOQOL-100 was developed to enable a brief but accurate assessment of the quality of life.

  7. Change From Baseline of Quality of Life Assessment Data Measured by World Health Organization Quality of Life (WHOQOL-BREF)- Environment Domain [ Time Frame: baseline and 24±2 weeks ]

  9. EuroQol (EQ) Visual Analogue Scale (VAS) [ Time Frame: baseline and 24±2 weeks ]
    The EQ VAS records the respondent's self-rated health on a vertical, visual analogue scale where the endpoints are labelled 'best imaginable health state' and 'worst imaginable health state. The scale goes from 0 to 100, a low value shows better physical health.
