Brief Title
Changes in NT-proBNP, Safety, and Tolerability in HFpEF Patients With a WHF Event (HFpEF Decompensation) Who Have Been Stabilized and Initiated at the Time of or Within 30 Days Post-decompensation (PARAGLIDE-HF)
Detailed Description
This study used a randomized, double-blind, double-dummy, active-controlled, parallel group design conducted across 100 centers in the US and Canada. The study duration was a maximum of 20 months (minimum follow up was 8 weeks).
Randomized patients were deemed hemodynamically stabilized and needed to meet all inclusion and none of the exclusion criteria. Patients were randomized 1:1 to LCZ696 or valsartan. Initial dose at randomization was determined based on the patient's previous dose of or lack of ACEi/angiotensin receptor blocker (ARB) immediately prior to current worsening heart failure (WHF) event (heart failure with preserved ejection fraction \[HFpEF\]) decompensation, or at the time of post-decompensation randomization.
LCZ696 dose or valsartan dose levels may have been increased to the targeted desired dose of 97/103 mg \[200 mg\] BID or valsartan 160 mg BID on an every 2-week basis or earlier based on clinical need and investigator judgment. Every effort was made to titrate to and maintain patients on the target dose level, as tolerated by the patient.
To maintain the blinding, patients were required to take their assigned active treatment tablet along with placebo matching the opposite treatment BID.
The protocol had 4 amendments. Protocol Version 00 (Original Protocol) included a double-blind phase through Week 8 followed by an open-label phase during Weeks 8 to 12. Protocol Amendment 01 omitted the open-label phase and followed patients for a maximum of 20 months in a double-blinded treatment phase. Throughout all protocol versions, the primary endpoint remained the time-averaged proportional change in N-terminal pro-brain natriuretic peptide (NT-proBNP) from Baseline to Weeks 4 and 8. The most recent protocol amendment (Amendment 04) reduced the sample size to approximately 450 patients (from 800) with 85% power for the primary endpoint, deemphasizing the statistical power for key secondary clinical endpoints; however, clinical events were still assessed as secondary endpoints.
No efficacy analyses include "OPEN LABEL' data. After Protocol Amendment 01, the open-label option was removed from the study, only the 233 patients randomized in the Double-blind Phase Sacubitril+ Valsartan (LCZ696) and the 233 patients randomized in the Double-blind Phase Valsartan arms were included in the efficacy analysis.

A Multicenter, Randomized, Double-blind, Double Dummy, Parallel Group, Active-controlled Study to Evaluate the Effect of Sacubitril/Valsartan (LCZ696) Versus Valsartan on Changes in NT-proBNP, Safety, and Tolerability in HFpEF Patients With a WHF Event (HFpEF Decompensation) Who Have Been Stabilized and Initiated at the Time of or Within 30 Days Post-decompensation (PARAGLIDE-HF)
Primary Outcomes
Outcome Description
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: Week - 8/Baseline.
NT-proBNP is a protein produced in large amounts by the heart when it is not working properly, as in heart failure.
Baseline value was the last non-missing assessment of plasma NT-proBNP before the first administration of study drug.

Secondary Outcomes
Outcome Description
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) or a 'loser'. Otherwise they are considered tied. The reported unit is the total "wins" or "ties" for each treatment group from performing such a hierarchical comparison.

Outcome Description
This endpoint calculated the cumulative number of the following composite events over time:
