Last updated: January 12, 2016
Last verified: January 2016
  Purpose
This is the first evaluation of the effects of LCZ696 on local and regional measures of aortic stiffness in subjects with mild to moderate hypertension and widened pulse pressure. The results of this exploratory study will help to understand the mechanism of action of LCZ696 and used to inform the design of future clinical studies with LCZ696 in subjects with cardiovascular diseases.

Primary Outcome Measures:
  • Change from baseline in ascending aorta distensibility at 12 weeks [ Time Frame: Baseline, 12 weeks ] [ Designated as safety issue: No ]
    Cardiovascular magnetic resonance imaging (MRI) scans will be obtained at baseline prior to randomization, at week 12 for the assessment of local aortic distensibility.

  • Change from baseline in proximal descending aorta distensibility at 12 weeks [ Time Frame: Baseline, 12 weeks ] [ Designated as safety issue: No ]
    Cardiovascular magnetic resonance imaging (MRI) scans will be obtained at baseline prior to randomization, at week 12 for the assessment of local aortic distensibility.

  • Change from baseline in distal descending aorta distensibility at 12 weeks [ Time Frame: Baseline, 12 weeks ] [ Designated as safety issue: No ]
    Cardiovascular magnetic resonance imaging (MRI) scans will be obtained at baseline prior to randomization, at week 12 for the assessment of local aortic distensibility.


Secondary Outcome Measures:
  • Change from baseline in local aortic strain at 12 weeks [ Time Frame: Baseline, 12 weeks ] [ Designated as safety issue: No ]
    Cardiovascular magnetic resonance imaging (MRI) scans will be obtained at baseline prior to randomization, at week 12 for the assessment of local aortic strain.

  • Change from baseline in regional aortic pulse wave velocity at 12 weeks [ Time Frame: Baseline, 12 weeks ] [ Designated as safety issue: No ]
    Cardiovascular magnetic resonance imaging (MRI) scans will be obtained at baseline prior to randomization, at week 12 for the assessment of regional aortic pulse wave velocity.

  • Change from baseline in Central blood pressure at 12 weeks [ Time Frame: Baseline, 12 weeks ] [ Designated as safety issue: No ]
  • Change from baseline in augmentation pressure at 12 weeks [ Time Frame: Baseline, 12 weeks ] [ Designated as safety issue: No ]
    Augmentation pressure is the added pressure during systole due to wave reflection.

  • Change from baseline in augmentation index at 12 weeks [ Time Frame: Baseline, 12 weeks ] [ Designated as safety issue: No ]
    Augmentation index is the percentage of the central pulse pressure due to wave reflection.

  • Change from baseline in pulse wave velocity at 12 weeks [ Time Frame: Baseline, 12 weeks ] [ Designated as safety issue: No ]
  • Number of patients with reported adverse events, serious adverse events and death [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
