Condition Intervention Phase
Hypertension Drug: Valsartan/HCTZ Drug: amlodipine Drug: HCTZ Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: A 10-week Multicenter,Forced-titration Study Using 24-hr ABPM to Evaluate the Efficacy of Valsartan/Hydrochlorothiazide (HCTZ) Treatment Regimen vs Conventional Treatment Regimen With Amlodipine and Hydrochlorothiazide (HCTZ) in Patients With Stage 2 Hypertension

Primary Outcome Measures:
  • -Change from baseline in mean 24-hr ambulatory systolic blood pressure (BP) after 10 weeks of treatment of valsartan/HCTZ versus amlodipine and HCTZ

Secondary Outcome Measures:
  • change from baseline in mean 24-hr ambulatory diastolic BP and pulse pressure after 10 weeks of treatment of valsartan/HCTZ versus amlodipine and HCTZ
  • Change from baseline in mean seated systolic and diastolic BP after 10 weeks of treatment of valsartan/HCTZ versus amlodipine and HCTZ
  • Compare the proportion of patients achieving blood pressure goal and tolerability after 10 weeks of treatment of valsartan/HCTZ versus amlodipine and HCTZ

Estimated Enrollment: 480
Study Start Date: December 2006
Study Completion Date: October 2007
Primary Completion Date: October 2007 (Final data collection date for primary outcome measure)
