Official Title: A Multi-national, Multi-center, Double-blind, Randomized, Parallel Study Comparing the Efficacy and Safety of Valsartan/Amlodipine 160/5 mg to Valsartan 160 mg Alone in Patients With Mild to Moderate Essential Hypertension Not Adequately Controlled With Valsartan 160 mg Monotherapy

Primary Outcome Measures:
  • Change in Mean Sitting Diastolic Blood Pressure (MSDBP) From Baseline to Week 8 Endpoint [ Time Frame: Baseline and Week 8 ] [ Designated as safety issue: No ]
    Three arterial blood pressure (BP) determinations were made after the participant was in the sitting position for 5 minutes according to the American Heart Association guidelines using a calibrated standard aneroid or mercury sphygmomanometer or a calibrated standard sphygmomanometer. The change in the MSDBP was calculated comparing the Week 8 readings to the readings taken at Baseline. The change from baseline in MSDBP was analyzed using an analysis of covariance model (ANCOVA) with treatment and center (pooled as appropriate) as factors and centered baseline MSDBP as a covariate.


Secondary Outcome Measures:
  • Change in Mean Sitting Systolic Blood Pressure (MSSBP) From Baseline to Week 8 Endpoint [ Time Frame: Baseline and Week 8 ] [ Designated as safety issue: No ]
    Three arterial blood pressure (BP) determinations were made after the participant was in the sitting position for 5 minutes according to the American Heart Association guidelines using a calibrated standard aneroid or mercury sphygmomanometer or a calibrated standard sphygmomanometer. The change in the MSSBP was calculated comparing the Week 8 readings to the readings taken at Baseline. The change from baseline in MSSBP was analyzed using an analysis of covariance model (ANCOVA) with treatment and center (pooled as appropriate) as factors and centered baseline MSSBP as a covariate

  • Percentage of Participants With a Diastolic Blood Pressure Response at 8 Week Endpoint [ Time Frame: Baseline and Week 8 ] [ Designated as safety issue: No ]
    The percentage of participants with a Diastolic Blood Pressure Response defined as the percentage of participants with a Mean Sitting Diastolic Blood Pressure (MSDBP) < 90 mmHg or a >= 10 mmHg reduction from baseline.

  • Percentage of Participants With Diastolic Blood Pressure Control at 8 Week Endpoint [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
    The percentage of participants with Diastolic Blood Pressure Control defined as the percentage of participants with a Mean Sitting Diastolic Blood Pressure (MSDBP) < 90 mmHg.

  • Percentage of Participants With Overall Blood Pressure Control at 8 Week Endpoint [ Time Frame: Week 8 ] [ Designated as safety issue: No ]
    The percentage of participants with Overall Blood Pressure Control defined as the percentage of participants with a Mean Sitting Systolic Blood Pressure (MSSBP)/Mean Sitting Diastolic Blood Pressure (MSDBP) < 140/90 mmHg.
