To discuss how Entrestocan help address a substantial unmet medical need
in heart failure with preserved ejection fraction (HFpEF)
•
The understanding of HFpEFhas evolved;PARAGON-HF contributes significantly
to this evolution
•Despite the narrowstatistical miss, a true albeit modest treatment effect ofEntresto
is apparentin the PARAGON-HF study population
‒Larger treatment effect observed in patients with lower LVEF and in women
•Evidence fromother trials, including PARADIGM-HF in HFrEF,increase confidence
in the treatment effect of Entresto in HFpEF
•Favorable safety profile in HFpEF, in line with the extensive experience in HFrEF
Why We Are Here Today
4
•Heart failure (HF) is segmented by left ventricular ejection fraction (LVEF)
‒HF with reduced ejection fraction (HFrEF)
‒HF with preserved ejection fraction (HFpEF)
•3.25 million HFpEF patients in the US
•Serious and debilitating disease
‒High patient burden driven by recurrent hospitalizations and reduced quality of life
‒Proportion of HF patients hospitalized with HFpEF is increasing, expected to be 50% in 2020
‒40%of patients re- admitted within 1 year
•No approved treatment for HFpEF

•Unique dual blocker of renin- angiotensin system (RAS) and neprilysin
•Superiority demonstrated over RAS inhibition alone in HFrEF
‒20% relative risk reduction in HF hospitalization or CV death
•Approved in 115 countries worldwide
•Global exposure>2.6 million patient-years

•Left ventricular ejection fraction
•History of heart failure phenotyping by ejection fraction –HFrEF,
HFpEF and HFmrEF
•Clinical characteristics of, and outcomes in, patients with HFrEF,
HFpEF and HFmrEF

•A clinical syndrome -causing breathlessness (dyspnea), fatigue/exertional limitation and
edema (leg/ankle swelling) caused by dysfunction of the heart (muscle, valves, endocardium,
pericardium, rate or rhythm).
•Common-Afflicts 1-2% of the population (up to 10% of older people)
•Disabling-Greatly reduced quality of life (worse than almost any other chronic condition)
with frequent ED attendances and high rates of hospitalization. Heart failure accounts for 5%
of all medical admissions; is the single most common cause of hospitalization in people >65
years of age.
•Costly-Accounts for 1-2% of health care spending, 70% of which is due to hospitalizations.
•Deadly-High mortality rate ( ~50% at 5 years) but varies according to type of heart failure.
•Progressive-worsens progressively over time, with development of additional
complications including renal dysfunction, anemia, atrial fibrillation and other arrhythmias.

defined by not having a “reduced” LVEF (<40%)
•HFmrEF–patients with “mid range” or “mildly reduced” LVEF
(
~40-50%) –not normal but not HFrEF; redefined HFpEF as

Overarching goal – slow progressive worsening over time
•Reduce rate of deterioration in symptoms and quality of life (or
even improve symptoms) –
physician evaluation (NYHA class), patient
self-assessment (KCCQ)
•Reduce episodes of worsening e.g. leading to ED visits and
hospital admission (and re- admissions) –
time-to-first event,
recurrent/repeat events
•Reduce mortality, where possible – generally only cardiovascular
mortality modifiable

Adapted from Dewan P et al Eur J Heart Fail 2020;22: 898-901
39
•Multiple effective therapies are available for patients with HFrEF, presently defined as a LVEF <40%
•The remaining patients with heart failure were originally described as having HFpEF, although,
recently, HFpEF has been re- defined –people with a LVEF 40- 50% have been categorized as
having HFmrEF and only those with a LVEF >50% now described as having HFpEF (arbitrary cut-
points)
•No treatments are approved for people with HFpEF and HFmrEF, although they account for 50% of
cases of heart failure and are increasing in incidence and prevalence (as the predominant
phenotypes in aging populations)
•Although patients HFpEF and HFmrEF have a lower mortality rate (and proportionately more non-
cardiovascular deaths) than patients with HFrEF, their rates of HF hospitalization are nearly as high
as in patients with HFrEF
•People with HFpEF and HFmrEF have at least as many symptoms and as great a reduction in
quality of life as patients with HFrEF
•Heart failure with LVEF ≥40% is an important unmet treatment need

Valsartan chosen as the active comparator to treat comorbidities
•~85% of patients treated with ACEi/ARB in prior HFpEF trials and prior to
PARAGON run-in
•Similar RAS blockade in both groups; sacubitril/valsartan 97/103 mg provides
similar plasma exposure as valsartan 160 mg
•Allowed assessment of incremental effect of sacubitril on RAS inhibition
•Of note, previous studies suggests a modest benefit from RAS inhibition
Key Design Considerations: Active Comparator
<<Yusuf et al. Lancet 2003;362:777– 81; Rogers et al. European Journal of Heart Failure 2014;16:33– 40.>>
48
Key Design Considerations: Recurrent Events
•HFpEF is characterized by frequent recurrent worsening HF events (HF hospitalization and Urgent HF visits)
•Each event is associated with worsening of long term prognosis
‒In the CHARM program (candesartan) the risk of death increased with each additional HF hospitalization, with an
~30% cumulative incremental risk associated with 2nd or 3rd HF hospitalization
•Traditional TTFE analysis ignore all events after the first event
•This approach more accurately reflects the true burden of the illness on the patient and the healthcare system
•Commonly used in other diseases where recurrent encounters are common (e.g. asthma, multiple sclerosis) and included in
June 2019 FDA guidance “Treatment for Heart Failure: Endpoints for Drug Development”

•Urgent, non- hospitalized, heart failure visits have similar prognostic and
discriminative ability as heart failure hospitalizations
•Incorporated into composite endpoint of recent heart failure trials (MADIT-CRT,
DAPA- HF) and included in June 2019 FDA guidance “Treatment for Heart Failure:
Endpoints for Drug Development”
‒Of 1582 worsening HF events, 95 (6.0%) were urgent HF visits.
•Patients whose first episode of worsening HF event was an urgent visit had
similar age, comorbidities, baseline NT-proBNP, and MAGGIC risk scores to
those in whom the first HF event was a hospitalization.

Clinical Endpoint Committee (CEC) Adjudication
Criteria for HF hospitalization
Strict CEC definition for adjudicating HF hospitalizations consistent with the Standardized Data
Collection for Cardiovascular Trials Initiative (SCTI) (Hicks et al 2018), all of the below required
from source documentation:
HF hospitalization
Unplanned presentation with HF exacerbation
Stay traversing change in calendar date
At least one symptom of worseningHF
At least two signs of worseningHF
Qualified treatments directed at treating HF
<<Hicks et al. Circulation 2018 137(9):961-972>>
63
While stringent adjudication criteria increased specificity, it may have discarded a
number of true HF hospitalization events that did not meet the strict definition,
thereby reducing sensitivity
FDA recommended an independent panel to re-adjudicate unconfirmed HF
hospitalizations:
•The trigger was not concern regarding the quality of the initial CEC adjudication but that
the strict definition used reduced the sensitivity
•Consisted of 3 independent, blinded HF experts
•Reviewed 566 investigator-reported but CEC unconfirmed HF hospitalizations
•Each expert ascribed a probability of being a true HF hospitalization based on clinical
judgement using CEC endpoint packages (100%, 75%, 50%, 25%, 0%)
•The 3 probabilities were averaged for each event and used in a multiple imputation
approach to include re-adjudicated events in the primary analysis

•Building on the pharmacodynamic and morphological benefits demonstrated in the Phase II trial,
PARAGON-HFwas the largestand only active-controlled PhaseIII studyinHFpEF
•Despite narrowly missing statistical significance for primary endpoint, the totality of evidence support a real
albeit modest benefit in the overall study population:
–Supportive analyses of the primary endpoint show a consistent treatment effect (13%-16%)
•Expanded composite endpoint incorporating urgent HF visits
•Investigator-reported endpoint events
•FDA-recommended re-adjudication of CEC -unconfirmed investigator reported HF hospitalizations
–Secondary efficacy endpoints (NYHA, KCCQ and renal composite endpoint) consistently favor
sacubitril/valsartan
•No new safety signals and the overall safety profile in HFpEF similar to HFrEF
•Benefit observed in overall trial population driven by large reductions in the total worsening HF events in
HFpEF patients with LVEF below normal

Sacubitril/Valsartan in HFpEF: Summary of Safety
Findings
107
•HFpEFis a syndrome (or syndromes –HFmrEF too?), causing disabling
symptoms and frequent hospitalization in older individuals, many of whom are
women, and for which there is no approved treatment
•The totality of evidence from PARAGON-HF supports the conclusion that
sacubitril/valsartan has clinical benefits, and a favorable benefit-to-risk profile, in
HFpEF, overall
•In a prespecified subgroup analysis, sacubitril/valsartan seemed to have more
benefit in patients with a LVEF at or below the median of 57% (and in women)
•Additional data to show that other drugs working on neurohumoral pathways also
seem to be beneficial in patients with a LVEF in lower part of the HFpEF range
•The potential reduction in events with sacubitril/valsartan in patients with a LVEF
≤median in PARAGON- HF was substantial and the safety profile is acceptable

Totality of Evidence Supports Benefit in HFpEF
•HFpEF is a debilitating disease with no approved therapy
•Entresto is approved in the HFrEF population
•Evidence supports extending use to adjacent HFpEF population to
