Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
A total of 2694 patients enrolled in the single-blind, placebo run-in period (2 to 4 weeks) of the study. A total of 1688 patients were randomized into the double-blind treatment period (8 weeks). Three patients were mis-randomized, as they were discontinued from the single-blind period and were not treated in the double-blind period.

1.  Primary:   Pairwise Comparison of Aliskiren/Amlodipine 150/5 mg vs. Aliskiren 150 mg on Change in Mean Sitting Diastolic Blood Pressure (msDBP)   [ Time Frame: Baseline to end of study (Week 8) ]

Measure Type Primary
Measure Title Pairwise Comparison of Aliskiren/Amlodipine 150/5 mg vs. Aliskiren 150 mg on Change in Mean Sitting Diastolic Blood Pressure (msDBP)
Measure Description The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. An automated BP measurement device and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, diastolic BP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements.

Measure Type Primary
Measure Title Pairwise Comparison of Aliskiren/Amlodipine 150/10 mg vs. Aliskiren 150 mg on Change in Mean Sitting Diastolic Blood Pressure (msDBP)
Measure Description The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. An automated BP measurement device and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, diastolic BP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements.

Measure Type Primary
Measure Title Pairwise Comparison of Aliskiren/Amlodipine 300/10 mg vs. Placebo on Change in Mean Sitting Diastolic Blood Pressure (msDBP)
Measure Description The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. An automated BP measurement device and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, diastolic BP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements.

Measure Type Secondary
Measure Title Pairwise Comparison of Aliskiren/Amlodipine 300/5 mg vs. Amlodipine 5 mg on Change in Mean Sitting Systolic Blood Pressure (msSBP)
Measure Description The arm in which the highest sitting diastolic pressures were found at study entry was the arm used for all subsequent readings. An automated BP measurement device and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, systolic BP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements.

27.  Secondary:   Percentage of Patients Achieving a Successful Systolic Blood Pressure Response   [ Time Frame: End of study (Week 8) ]

Measure Type Secondary
Measure Title Percentage of Patients Achieving a Successful Systolic Blood Pressure Response
Measure Description Blood pressure response in msSBP is defined as a mean sitting systolic blood pressure < 140 mmHg or a >= 20 mmHg reduction from baseline. A calibrated sphygmomanometer and appropriate size cuff were used to measure arterial sitting blood pressure (BP) at trough with the arm supported at the level of the heart. At each study visit, after having the patient in a sitting position for at least 5 minutes, systolic/diastolic BP were measured 3 times at 1-2 minute intervals. A mean was calculated from the 3 measurements.
Time Frame End of study (Week 8)  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
All patients who were randomized. Following the intent-to-treat principle, patients will be analyzed according to the treatment they were assigned to at randomization. Patients with baseline and Endpoint msDBP values were included in this analysis.
