Primary Outcome Measures:
  • Change in nocturnal systolic blood pressure level [ Time Frame: Baseline and 8 weeks ] [ Designated as safety issue: No ]

    Change at the end of a treatment period (Week 8) from the beginning point of an observation period

    *Nocturnal systolic blood pressure level: the mean value of systolic arterial pressure during night (during sleeping)



Secondary Outcome Measures:
  • Efficacy [ Time Frame: Baseline and 8 weeks ] [ Designated as safety issue: No ]
    • Change in the absolute value in difference with targeted value* (15 percent) of nocturnal systolic blood pressure fall**
    • Change in nocturnal diastolic blood pressure level
    • Change in 24-hour mean systolic blood pressure level
    • Change in 24-hour mean diastolic blood pressure level
    • Change in urinary micro albumin excretion
    • Change in N-terminal pro-B-type natriuretic peptide (NT-proBNP)
    • Change in high-sensitivity cardiac troponin T (hs-cTnT)
    • Change in fasting glucose
    • Change in insulin resistance index***

      • The targeted value has been set as the median of the dipping rate, normal type of nocturnal blood pressure variation, rate of nocturnal blood pressure fall (10-20 percent) ** Rate of nocturnal blood pressure fall: calculated as (awake SBP-sleep SBP)/awake SBP *** Insulin resistance index = fasting insulin level x fasting glucose level / 405


Other Outcome Measures:
  • Safety [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]

    Adverse event

    - For Safety Analysis Set (SAS), count the onset rate of adverse events in term from the start of treatment period (Week 0) to the end (Week 8) in each group
