Primary Outcome Measures:
  • DBP and SBP Change From Baseline in Mean 24-hour Ambulatory Blood Pressure Monitoring (ABPM) Mean [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    ABPM measurements were taken every 20 minutes throughout the day and night by the validated SpaceLabs Model 90217 monitor.


Secondary Outcome Measures:
  • Change From Baseline in ABPM Hourly Mean DBP and SBP, Starting 1 Hour After Dosing [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    Changes from baseline in DBP and SBP hourly means over the 24-hour dosing interval as measured by ABPM after 8 weeks of treatment with T80/A5

  • Trough to Peak (T/P) Ratio for DBP and SBP After 8 Weeks of Treatment [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    Calculated on the basis of changes in hourly means from baseline. Trough is defined as the mean of the last three hours of the 24-hour dosing interval. Peak is the greatest reduction in hourly means in hours 2 to 8 after dosing. All measurements are using ABPM.

  • Change From Baseline to End of Study in DBP and SBP [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    Manually measured in-clinic DBP and SBP

  • ABPM Hourly Mean DBP and SBP at Baseline and the End of the Study, Starting 1 Hour After Dosing [ Time Frame: 0 and 8 weeks ] [ Designated as safety issue: No ]
    DBP and SBP hourly means over the 24-hour dosing interval as measured by ABPM at baseline and after 8 weeks of treatment

  • Treatment Emergent Adverse Events [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    Electrocardiogram, laboratory parameters and physical examinations were performed and any abnormal findings were recorded within the adverse events

  • Change From Baseline to End of Study in In-clinic Pulse Rate [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
