Brief Summary:
The primary objective of this trial is to demonstrate that the fixed-dose combination of T80/HCTZ25 is superior as first line therapy in reducing seated trough cuff Systolic Blood Pressure(SBP) compared to the monotherapy of T80 in patients with grade 2 or grade 3 hypertension (SBP>=160 mmHg and Diastolic Blood Pressure(DBP)>=100 mmHg).

Primary Outcome Measures :
  1. Change From Baseline in Mean Seated Trough Cuff Systolic Blood Pressure (SBP) to Week 7 [ Time Frame: Baseline and Week 7 ]
    The SBP value at baseline was subtracted from the SBP value at Week 7.


Secondary Outcome Measures :
  1. Change From Baseline in Mean Seated Trough Cuff SBP to Week 5 [ Time Frame: Baseline and Week 5 ]
    The SBP value at baseline was subtracted from the SBP value at Week 5.

  2. Change From Baseline in Mean Seated Trough Cuff SBP to Week 3 [ Time Frame: Baseline and Week 3 ]
    The SBP value at baseline was subtracted from the SBP value at Week 3.

  3. Change From Baseline in Mean Seated Trough Cuff Diastolic Blood Pressure (DBP) to Week 7 [ Time Frame: Baseline and Week 7 ]
    The DBP value at baseline was subtracted from the DBP value at Week 7.

  4. Number of Patients With SBP Control (SBP < 140 mmHg) at Week 7 [ Time Frame: Week 7 timepoint ]
    SBP control is defined as SBP < 140 mmHg.

  5. Number of Patients With SBP Control (SBP < 140 mmHg) at Week 5 [ Time Frame: Week 5 timepoint ]
    SBP control is defined as SBP < 140 mmHg

  6. Number of Patients With SBP Control (SBP < 140 mmHg) at Week 3 [ Time Frame: Week 3 timepoint ]
    SBP control is defined as SBP < 140 mmHg

  7. Number of Patients With DBP Control (DBP < 90 mmHg) at Week 7 [ Time Frame: Week 7 timepoint ]
    DBP control is defined as DBP<90 mmHg

  8. Number of Patients With DBP Control (DBP < 90 mmHg) at Week 5 [ Time Frame: Week 5 timepoint ]
    DBP control is defined as DBP<90 mmHg

  9. Number of Patients With DBP Control (DBP < 90 mmHg) at Week 3 [ Time Frame: Week 3 timepoint ]
    DBP control is defined as DBP<90 mmHg

  10. Number of Patients With Blood Pressure (BP) Control at Week 7 [ Time Frame: Week 7 timepoint ]
    BP control is defined as SBP<140 mmHg and DBP < 90 mmHg and is adjusted for baseline SBP

  11. Number of Patients With BP Control at Week 7 [ Time Frame: Week 7 timepoint ]
    BP control is defined as SBP<140 mmHg and DBP < 90 mmHg and is adjusted for baseline DBP

  12. Number of Patients With Systolic Blood Pressure (SBP) Response at Week 7 [ Time Frame: Week 7 timepoint ]
    SBP response is defined as SBP<140 mmHg or a reduction of >= 15 mmHg

  13. Number of Participants With DBP Response at Week 7 [ Time Frame: Week 7 timepoint ]
    DBP response is defined as DBP<90 mmHg or a reduction of >= 10 mmHg

  14. BP Categories at Week 7 [ Time Frame: Week 7 timepoint ]

    BP categories comprise:

    • BP optimal (SBP <120 mmHg and DBP <80 mmHg)
    • BP normal (SBP <130 mmHg and DBP <85 mmHg but not 'optimal')
    • BP high normal (SBP <140 mmHg and DBP <90 mmHg but not 'normal')
    • Grade 1 hypertension (SBP <160 mmHg and DBP <100 mmHg but not 'high normal')
    • Grade 2 hypertension (SBP <180 mmHg and DBP <110 mmHg but not 'Grade 1 hypertension')
    • Grade 3 hypertension (SBP ≥180 mmHg or DBP ≥110 mmHg)
