Brief Summary

PARADOR is multisite, randomized, double-blind, phase IV clinical trial to compare the effect of sacubitril/valsartan (Entresto™) to enalapril (Vasotec®) on blood vessel function in subjects with heart failure with reduced ejection fraction (HFREF).

Outcome Measures

Primary Outcomes (1)

  • Flow Mediated Vasodilation

    To test the hypothesis that sacubitril/valsartan will improve endothelial function compared to enalapril, evidenced by increased flow mediated vasodilation (FMD) measured by brachial artery reactivity test (BART)

    At study treatment completion (10 weeks)

Secondary Outcomes (1)

  • B-type natriuretic peptide

    At study treatment completion (10 weeks)

Study Arms (2)

Sacubitril/Valsartan

ACTIVE COMPARATOR

Sacubitril/valsartan 100mg (Dose Level 1) titrated up if tolerated to 200 mg twice daily (Dose Level 2)

Drug: sacubitril/valsartan

Enalapril

ACTIVE COMPARATOR

Enalapril 5mg (Dose Level 1) titrated up if tolerated to 10mg twice daily (Dose Level 2)

Drug: Enalapril

  • Enrolled in another clinical trial or has used of any investigational drugs, biologics, or devices within 30 days prior to randomization
  • Women who are pregnant or breast-feeding
  • Not suitable for study participation due to other reasons at the discretion of the investigator
