Clinical Trial Summary

The purpose of this study was to determine the effect of sacubitril/valsartan (LCZ696) vs. Enalapril on improvement in erectile function and ability in male patients with chronic heart failure with reduced ejection fraction and erectile dysfunction.

Description:

The purpose of this study was to evaluate the effect of sacubitril/valsartan in improving erectile function in male patients with chronic heart failure (NYHA II) and reduced ejection fraction (HFrEF) and erectile dysfunction (ED). Data from this study was intended to provide a thorough understanding of the impact of sacubitril/valsartan on male sexual function and therefore quality of life.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Erectile Function Score Using Index of Erectile Function (IIEF-15)	The International Index of Erectile Function (IIEF-15) was used to assess erectile function in male patients with chronic heart failure. The IIEF-15 is a patient self-reported assessment of erectile dysfunction (ED) and consists of 15 questions assessing different aspects associated with ED. The domain evaluating erectile function consists of items 1, 2, 3, 4, 5 & 15 and its total score was used here. Total score range =1-30. Items 1-5 is 6-point Likert-type scale from '0' (= No sexual activity), '1' (=Almost never or never) to '5' (= Almost always or always). Items 15 is 5-point Likert-type scale from '1' (= very low) to '5 '(= very high). Higher score indicates better outcome	Week 12 (3 months)
Secondary	Summary of Change From Baseline in Self-reported Frequency of Sexual Activity Per Week	Assessment of early-onset effect and end of study effect, regarding improvement in sexual activity, using patient's self-reported frequency of sexual activity per week. Patient was asked to complete a diary assessing sexual activity on a weekly basis	Baseline, Week 4, Week 12
Secondary	Summary of Change From Baseline in NT-proBNP Levels	Change in n-terminal prohormone of brain natriuretic peptide (NT-proBNP) levels compared to baseline assessed at Week 4 and Week 12	Baseline, Week 4, Week 12
