Time-averaged Proportional Change in NT proBNP From Baseline to Weeks 4 and 8 Primary · Baseline, Average of Week 4 and Week 8

To demonstrate the effect of sacubitril/valsartan vs. valsartan on time-averaged proportional change in N-terminal pro-brain natriuretic peptide (NT-proBNP) from baseline to weeks 4 and 8 in heart failure with preserved ejection fraction (HFpEF) patients with a worsening heart failure event (HFpEF decompensation) who have been stabilized for and initiated at the time of or within 30 days post-decompensation. Plasma NT-proBNP (pg/mL) values were averaged from Week 4 and Week 8 visits. The change from baseline to average of Week 4 and Week 8 was expressed as the geometric mean of the ratio: Wee

Number of Pairwise Comparisons With Wins or Ties in the Endpoint Adjudication Committee (EAC)-Adjudicated Composite Hierarchical Outcome Secondary · Up to 84 weeks

This hierarchical composite endpoint consists of 4 ordered components: 1. Time to CV death, 2. Number and times of HF hospitalizations during follow-up, 3. Number and times of urgent HF visits during follow-up, 4. Time averaged proportional change in NT-proBNP from baseline to Weeks 4 and 8. This endpoint was analyzed estimating the unmatched win ratio by comparing every participant in the sacubitril/valsartan arm to every participant in the valsartan arm to determine a winner (unmatched pairing method). For every pair, a patient is labelled a 'winner' (i.e. achieve a better clinical outcome)

EAC Adjudicated Recurrent Composite Events Secondary · Up to Week 84

This endpoint calculated the cumulative number of the following composite events over time: * CV death * recurrent HF hospitalizations * recurrent urgent HF visits The time to these recurrent events was analyzed using the semi-parametric proportional rates model (abbreviated as LWYY model). The exposure-adjusted rate per 100 subject years (EAR) was calculated diving the total number of events by 100 subject years (total exposure up to event/censoring). The role of the Endpoint Adjudication Committee (EAC) was to ensure that all treatment outcomes were judged uniformly, using standard criter

Proportional Change in NT-proBNP From Baseline to Week 8 Secondary · Baseline and Week 8

This endpoint intended to assess the effect of sacubitril/valsartan vs. valsartan on change in N-terminal pro-brain natriuretic peptide (NT-proBNP) from baseline to Week 8. NT-proBNP is a protein produced in large amounts by the heart when it is not working properly, as in heart failure. The change from baseline to Week 8 was expressed as the geometric mean of the ratio: Week 8/Baseline.

Proportional Change From Baseline in Hs-Troponin at Weeks 4 and 8 Secondary · Baseline, Week 4 and Week 8

This endpoint intended to assess the effect of sacubitril/valsartan vs. valsartan on change from baseline in high sensitivity (hs)-Troponin at Weeks 4 and 8. Analysis was repeated for both the visits, Week 4 and Week 8 separately. Hs-Troponin-T is a biomarker that is released from the heart under stress or injury conditions. The change from baseline to Week 4 and Week 8 was expressed as the geometric mean of the ratio: Week 4 or Week 8/Baseline.

The dosing level has been summarized by treatment group and in-/out-of-hospital randomization status. The dose levels used were: Dose Level 1: 40 mg valsartan or 24/26 mg \[50 mg\] LCZ696, BID; Dose Level 2: 80 mg valsartan or 49/51 mg \[100 mg\] LCZ696, BID; Dose Level 3: 160 mg valsartan or 97/103 mg \[200 mg\] LCZ696, BID Patients counted as "Off Treatment" are those who prematurely permanently discontinued study treatment but continued with visits. Patients counted as "No Treatment" are those who permanently discontinued with both study treatment and study visits
