Current Secondary Outcome Measures ^ICMJE

Change From Baseline in Mean Sitting Diastolic Blood Pressure (MSDBP) at Week 8 [ Time Frame: Baseline and week 8 ]
To evaluate change from baseline in MSDBP after 8 weeks of treatment with an aliskiren, amlodipine, and HCTZ treatment regimen versus an aliskiren and amlodipine treatment regimen in minority patients with Stage 2 hypertension.
Percentage of Patients Achieving Blood Pressure Control (Defined as MSSBP < 140 mmHg and MSDBP < 90 mmHg) During 8 Weeks [ Time Frame: 8 weeks ]
To evaluate the cumulative percentage of patients achieving Blood Pressure control (defined as patients achieving an MSSBP <140 mmHg and MSDBP <90 mmHg) during 8 weeks of treatment with an aliskiren, amlodipine, and HCTZ treatment regimen versus an aliskiren and amlodipine treatment regimen in minority patients with Stage 2 hypertension. Cumulative refers to achieving BP control before or at the corresponding visit.
Percentage of Responders (Defined as Patients With MSSBP < 140 mmHg or a Reduction From Baseline in MSSBP of ≥20 mmHg) During 8 Weeks. [ Time Frame: 8 weeks ]
To compare the cumulative percentage of responders (defined as patients with MSSBP <140 mmHg or a decrease from baseline ≥20 mmHg) during 8 weeks of treatment with an aliskiren, amlodipine, and HCTZ treatment regimen versus an aliskiren and amlodipine treatment regimen in minority patients with Stage 2 hypertension. Cumulative refers to achieving a response before or at the corresponding visit.

Original Secondary Outcome Measures ^ICMJE

Change from baseline in MSDBP [ Time Frame: 8 weeks ]
Percentage of patients achieving blood pressure (BP) control (defined as MSSBP < 140 mmHg and MSDBP < 90) [ Time Frame: 8 weeks ]
Percentage of responders (defined as patients with MSSBP < 140 mmHg or a reduction from baseline in US MSSBP of > 20 mmHg) [ Time Frame: 8 weeks ]
Change in MSSBP in patients with baseline MSSBP ≥ 180 mmHg and < 200 mmHg and Type 2 diabetes mellitus [ Time Frame: 8 weeks ]
Safety and tolerability of aliskiren, amlodipine and HCTZ treatment versus an aliskiren and amlodipine treatment in minority patients with Stage 2 hypertension [ Time Frame: 8 weeks ]

Brief Title ^ICMJE

Aliskiren/Amlodipine/Hydrochlorothiazide (HCTZ) Versus Aliskiren/Amlodipine in US Minority Patients With Stage II Systolic Hypertension

Official Title ^ICMJE

An 8-week Multicenter, Randomized, Double-blind, Active Controlled, Parallel Group, Forced Titration Study to Evaluate the Efficacy and Safety of Aliskiren/Amlodipine/HCTZ Compared to Aliskiren/Amlodipine in US Minority Patients With Stage 2 Hypertension

Brief Summary

Study Arms

Experimental: Triple Therapy (Aliskiren/Amlodipine/HCTZ)
At week 0 patients were randomized to aliskiren/amlodipine 150/5 mg. At week 1, patients were force titrated to aliskiren/amlodipine/HCTZ 150/5/12.5 mg. At week 2, patients were force titrated to aliskiren/amlodipine/HCTZ 300/5/25 mg. At week 4, patients were force titrated to aliskiren/amlodipine/HCTZ 300/10/25 mg.

Intervention: Drug: Aliskiren/Amlodipine and Hydrochlorothiazide (HCTZ)
Active Comparator: Dual Therapy (Aliskiren/Amlodipine)
At week 0 patients were randomized to amlodipine 5 mg. At week 1, patients were force titrated to aliskiren/amlodipine 150/5 mg. At week 2, patients were force titrated to aliskiren/amlodipine 300/5 mg. At week 4, patients were force titrated to aliskiren/amlodipine 300/10 mg.

Intervention: Drug: Aliskiren/Amlodipine
