Inclusion Criteria
  • Patients who are eligible and able to participate in the study, and who give written informed consent before any assessment is performed.
  • Men or women 18 years and older.
  • Patients with Stage 2 systolic hypertension; defined as having a MSSBP ≥160 mmHg and <180 mmHg at Visit 5 (randomization).
Exclusion Criteria
  • Use of aliskiren or participation in a clinical trial that had aliskiren as treatment within 30 days of Visit 1.
  • Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test (>5 mIU/ml).
  • Women of child-bearing potential (WOCBP), defined as all women physiologically capable of becoming pregnant, including women whose career, lifestyle, or sexual orientation precludes intercourse with a male partner and women whose partners have been sterilized by vasectomy or other means, UNLESS they meet the following definition of post-menopausal: 12 months of natural (spontaneous) amenorrhea or 6 months of spontaneous amenorrhea with serum FSH levels >40 mIU/m or 6 weeks post surgical bilateral oophorectomy with or without hysterectomy OR are using one or more of the following acceptable methods of contraception: surgical sterilization (e.g., bilateral tubal ligation), hormonal contraception (implantable, patch, oral), and double-barrier methods. Reliable contraception should be maintained throughout the study and for 7 days after study drug discontinuation.
  • Severe hypertension (an office cuff MSDBP ≥110 mmHg and/or MSSBP ≥180 mmHg).
  • Refractory hypertension, defined as unresponsive to triple drug therapy at the maximum dose of each drug, one of which must be a diuretic, and not at blood pressure goal (140/90 mmHg).
  • Patients treated with more than 3 antihypertensive medications (each component of a combination drug counts individually).
  • History or evidence of a secondary form of hypertension.

Primary Outcome Measures
NameTimeMethod
Change From Baseline in Mean Sitting Systolic Blood Pressure (MSSBP) at Week 8Baseline to Week 8

To compare the change from baseline in MSSBP after 8 weeks of treatment with a valsartan and aliskiren treatment regimen (160/150 mg, 320/300 mg) versus a valsartan treatment regimen (160 mg, 320 mg) in patients with Stage 2 Hypertension.

Secondary Outcome Measures
NameTimeMethod
Change From Baseline in Mean Sitting Diastolic Blood Pressure (MSDBP) at Week 8Baseline to Week 8

To compare the change in MSDBP after 8 weeks of treatment with a valsartan and aliskiren treatment regimen (160/150 mg, 320/300 mg) versus a valsartan (160 mg, 320 mg) treatment regimen in patients with Stage 2 Hypertension.

Percentage of Patients Achieving Blood Pressure Control (Defined as Patients Achieving a MSSBP <140 mmHg and MSDBP <90 mmHg) at Week 8At Week 8

To evaluate the percentage of patients achieving blood pressure control (defined as patients achieving a MSSBP \<140 mmHg and MSDBP \<90 mmHg) at week 8 following treatment with a valsartan and aliskiren treatment regimen (160/150 mg, 320/300 mg) versus a valsartan treatment regimen (160 mg, 320 mg) in patients with Stage 2 Hypertension.

Percentage of Responders (Defined as Patients With MSSBP <140 mmHg or a Decrease From Baseline ≥20 mmHg) at Week 8At Week 8

To compare the percentage of responders (defined as patients with MSSBP \<140 mmHg or a decrease from baseline ≥20 mmHg) at week 8 following treatment with a valsartan and aliskiren treatment regimen (160/150 mg, 320/300 mg) versus a valsartan treatment regimen (160 mg, 320 mg) in patients with Stage 2 Hypertension.

Mean Change From Baseline in Plasma Renin Activity (PRA) at Week 8Baseline to Week 8

To assess the change from baseline in PRA after 8 weeks of treatment with a valsartan and aliskiren treatment regimen (160/150 mg, 320/300 mg) versus a valsartan treatment regimen (160 mg, 320 mg) in patients with Stage 2 Hypertension.

Mean Change From Baseline in Plasma Renin Concentration (PRC) at Week 8Baseline to Week 8

To assess the change from baseline in PRC after 8 weeks of treatment with a valsartan and aliskiren treatment regimen (160/150 mg, 320/300 mg) versus a valsartan treatment regimen (160 mg, 320 mg) in patients with Stage 2 Hypertension.
