Further study details as provided by Novartis:

Primary Outcome Measures:
  • Difference in insulin sensitivity index after treatment with LCZ696 or amlodipine [ Time Frame: After 8 weeks of treatment ] [ Designated as safety issue: No ]
    The insulin sensitivity index will be assessed by hyperinsulinemic euglycemic clamp


Secondary Outcome Measures:
  • Subcutaneous adipose tissue lipolysis at rest [ Time Frame: After 8 weeks of treatment ] [ Designated as safety issue: No ]
    Assessment will by done by microdialysis.

  • Oxidative metabolism at rest [ Time Frame: After 8 weeks of treatment ] [ Designated as safety issue: No ]
    Assessment will be done by indirect calorimetry

  • Number of patients with abnormal laboratory values, vital signs, ECGs [ Time Frame: During 8 weeks of treatment ] [ Designated as safety issue: No ]
    Tolerability will be assessed by Physical examination, vital signs, including serial lupine BP and pulse measurements, laboratory evaluations (hematology, blood chemistry, urinalysis), ECG, and adverse event monitoring


Enrollment: 97
