NCT00993109

  Purpose

This will be a multi-center, prospective, randomized, open-label, parallel design, two arm comparator trial. In the proposed study, the investigators will compare low-dose combination therapy of Nifedipine GITS/OROS plus Valsartan with up-titrated monotherapy of Valsartan with respect to their blood pressure-decreasing effects in patients with essential hypertension.The study consists of a screening visit, followed by randomization and administration of either Nifedipine GITS/OROS 30 mg in combination with Valsartan 80 mg or Valsartan 160 mg for 12 weeks of treatment.The primary efficacy parameters will be mean SBP and DBP on office BP monitoring at 12 weeks of treatment compared to baseline.

Primary Outcome Measures:
  • Mean Systolic BP and Diastolic BP on office Blood Pressure monitoring [ Time Frame: Baseline and 12 weeks of treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Response rate (>/=10mmHg decrease of office SBP and >/=5mmHg decrease of office DBP) [ Time Frame: 8 and 12 weeks of treatment ] [ Designated as safety issue: No ]
  • Control rate (</=140/90 of office BP) [ Time Frame: 8 and 12 weeks of treatment ] [ Designated as safety issue: No ]
  • Change in pulse pressure (difference between SBP and DBP) [ Time Frame: 12 weeks of treatment ] [ Designated as safety issue: No ]
  • Reduction in Urinary microalbumin excretion(UAE) in patients with microalbuminuria [ Time Frame: Baseline and 12 weeks of treatment ] [ Designated as safety issue: No ]
  • Adverse Event reporting [ Time Frame: At the start, every 4 weeks during treatment and at the end of treatment ] [ Designated as safety issue: Yes ]
  • Vitals signs [ Time Frame: At the start, every 4 weeks during treatment and at the end of treatment ] [ Designated as safety issue: Yes ]
  • Laboratory tests [ Time Frame: At the start and at the end of treatment ] [ Designated as safety issue: Yes ]

  • BMI <33 kg/m2

Exclusion Criteria:

  • Participation in any clinical investigational drug study within the previous 12 weeks
  • Concomitant treatments with:

    1. Any anti-hypertensive treatment other than Valsartan 80 mg
    2. Cytochrome P450-3A4 inhibitors or inducers
    3. Potassium-sparing diuretics
  • Severe hypertension (DBP >/= 110 mm Hg and/or SBP >/= 180 mm Hg) and/or evidence of secondary forms of hypertension
  • Any of the following cardiovascular diseases:
  • History of cardiovascular shock
  • Myocardial infarction or unstable angina within the previous 6 months
  • Severe cardiac valve disease
  • Past or present severe rhythm or conduction disorder.
  • Cerebrovascular ischemic event and/or history of intracerebral hemorrhage or subarachnoid hemorrhage (SAH) within the previous 12 months
  • Type 1 or 2 diabetes mellitus
