Brief Summary: The purpose of this study was to investigate the effects of initiation of sacubitril/valsartan vs enalapril treatment on objective measures of both waking activity and sleep in subjects with heart failure with reduced ejection fraction.

Detailed Description: Not available

Recruitment & Eligibility

Status: COMPLETED

Sex: All

Target Recruitment: 140

Inclusion Criteria

Written informed consent must be obtained before any assessment is performed.
Men and women between 18 and 80 years of age
Subjects diagnosed with NYHA class II or III heart failure and with reduced ejection (HFrEF).

(Reduced ejection is defined as left ventricular EF ≤ 40%. LVEF ≤40% may be determined via any local measurement within the past 6 months prior to signing consent, using echocardiography, multi gated acquisition scan (MUGA), CT scanning, MRI or ventricular angiography provided no subsequent study documenting an EF of >40%. If the EF measurement is expressed as a value range, the average of the range endpoint values should be used as the EF).

Subjects must be a candidate for treatment with sacubitril/valsartan as per USPI.
Subjects must be living in a traditional residence, apartment, or non-communal adult home where they can move about freely and frequently and are primarily responsible for scheduling their sleep and daily activities.

Key

Exclusion Criteria

Subjects with a history of hypersensitivity to any of the study drugs, including history of hypersensitivity to drugs of similar chemical classes, or allergy to ACEIs, ARBs, or NEP inhibitors as well as known or suspected contraindications to the study drugs.
Subjects with a history of angioedema drug related or otherwise
Subjects with symptomatic hypotension or systolic blood pressure <100 mmHg at screening or <95 mmHg at randomization
Subjects with any conditions in skin or upper extremities which would limit the ability to tolerate a wrist-worn actigraphy device on the non-dominant arm for 24 hours/day for the duration of the study.
Subjects who are non-ambulatory or use mobility assistive devices such as motorized devices, wheelchairs, or walkers. The use of canes for stability while ambulating is acceptable.
Subjects with physical activity impairment primarily due to conditions other than heart failure such as:

peripheral vascular disease
neurologic disease affecting activity or mobility

Arm && Interventions

Group	Intervention	Description
Enalapril	sacubitril/valsartan (LCZ696)	Double blind treatment epoch: Patients randomized to this arm received 1 tablet of enalapril and 1 tablet of matching placebo sacubitril/valsartan twice daily for 8 weeks. All Patients began the study on Dose Level 1 (i.e. 2.5 mg enalapril BID). Patients may have been sequentially up-titrated to achieve desired dose of Dose Level 3 (i.e. 10 mg enalapril BID). Patients not tolerating dose escalation could have been titrated down to next lower dose level. Open-label treatment epoch: All patients entering this epoch (8 weeks) were given sacubitril/valsartan 49/51 mg BID (Dose Level 2) unless they completed the double-blind treatment epoch on enalapril Dose Level 1. Instead, these patients entered open-label epoch on Dose Level 1 of sacubitril/valsartan. Patients may have been sequentially up-titrated to achieve desired dose of Dose Level 3 of sacubitril/valsartan. Patients not tolerating dose escalation could have been titrated down to next lower dose level.
Sacubitril/Valsartan	sacubitril/valsartan (LCZ696)	Double blind treatment epoch: Patients randomized to this arm received 1 tablet of sacubitril/valsartan and 1 tablet of matching placebo enalapril twice daily for 8 weeks. All Patients began the study on Dose Level 1 (i.e. 24/26 mg sacubitril/valsartan BID). Patients may have sequentially been up-titrated to achieve desired dose of Dose Level 3 (i.e. 97/103 mg sacubitril/valsartan BID). Patients not tolerating dose escalation could have been titrated down to next lower dose level. Open-label treatment epoch: All patients entering this epoch (8 weeks) were given sacubitril/valsartan 49/51 mg BID (Dose Level 2) unless they completed the double-blind treatment epoch on Dose Level 1.

Primary Outcome Measures

Name	Time	Method
Ratio of Mean Activity Counts Collected During the Most Active 30 Minutes of the Subject's Day Between Week 8 and Baseline	Baseline, week 8	The primary endpoint is the ratio in mean activity counts collected during the most active 30 minutes of the subject's day between the final randomized treatment phase measurement (mean of endpoint data collected each day during week 8) and baseline phase (mean of endpoint data collected each day during week -1), as measured by wrist-worn accelerometer collected actigraphy (total counts per 30 min period collected during the most active 30 minutes of each day). A ratio \> 1 indicates an increase in mean activity counts from baseline to week 8.
