Brief summary:
This pilot study will assess the impact of sacubitril/valsartan (trade name Entresto) on the elevated pulmonary artery pressures in patients with heart failure with reduced ejection fraction, measured using a previously implanted hemodynamic monitoring device (CardioMEMS).

Detailed description:
Angiotensin-converting enzyme inhibitors (ACEi) have been a cornerstone treatment for patients with heart failure and reduced ejection fraction (HFrEF) for over 25 years. They are included in every major set of guidelines for HFrEF management. Angiotensin receptor blockers (ARB's, such as valsartan) have similarly been shown to decrease the mortality rate of patients with HFrEF for patients who are unable to tolerate ACEi therapy.

The newest neurohormonal therapy approved for heart failure (August 2015) is sacubitril/valsartan (trade name Entresto). This medication is the first of a new family of agents (ARNI = angiotensin receptor antagonist with neprilysin inhibitor), combining the approved angiotensin receptor blocker valsartan with sacubitril, an inhibitor of neprilysin, which is a neutral endopeptidase that degrades endogenous vasoactive peptides. Treatment with sacubitril increases circulating levels of natriuretic peptides, which have been shown to facilitate natriuresis and vasodilation. Although the precise mechanisms responsible for benefit in heart failure remain unclear, sacubitril/valsartan may reduce the fluid retention and vasoconstriction that contribute to heart failure symptoms, and may also decrease apoptosis and remodeling that lead to disease progression. There is limited data about the incremental acute and long-term hemodynamic effects of composite neprilysin/angiotensin-receptor inhibitors over enalapril, and these data may provide important mechanistic insights.

Progress in HF management outside the hospital has included validation of a strategy of ongoing monitoring of pulmonary artery pressures every day from home via a monitor implanted in a distal pulmonary artery, the CardioMEMS device. The information is transmitted to a website where it is reviewed by the HF team, who can intervene to adjust diuretics and other medications by phone to avert decompensation and re-hospitalization. The device received FDA approval in mid 2014, and is now being implanted in many cardiac catheterization laboratories, including at Brigham and Women's Hospital. The pressure information is reviewed regularly by the HF management team who are in regular contact with the patient to aid in management decisions.

In summary, this pilot study will assess the impact of sacubitril/valsartan, an approved drug for heart failure with reduced ejection fraction (HFrEF) on the elevated pulmonary artery pressures measured using an implanted monitoring device that is also approved for such patients. Both the medication and the device will be used according to approved indications.

Arms:
arm 1: Group A will receive sacubitril/valsartan + placebo for weeks 1-12. and then sacubitril/valsartan only for weeks 13-32. All subjects in Group A will also receive longitudinal pulmonary artery pressure monitoring using a previously placed implantable hemodynamic monitor (CardioMEMS device). arm 2: Group B will receive an Angiotensin-Converting Enzyme Inhibitor (ACEi) or Angiotensin II Type 1 Receptor Blocker (ARB) + placebo for weeks 1-6 (depending on previous background therapy) and then switch to sacubitril/valsartan + placebo for weeks 7-12.

Group B will then receive sacubitril/valsartan only for weeks 13-32. All subjects in Group B will also receive longitudinal pulmonary artery pressure monitoring using a previously placed implantable hemodynamic monitor (CardioMEMS device).

Interventions: intervention 1: Implantable Hemodynamic Monitor intervention 2: Angiotensin-Converting Enzyme Inhibitor intervention 3: Angiotensin II Type 1 Receptor Blocker intervention 4: sacubitril/valsartan
Intervention descriptions: intervention 1: The CardioMEMS device is an implantable pulmonary artery pressure monitor that is FDA-approved for use in patients with symptomatic heart failure and previous heart failure hospitalization. Patients eligible for this study are those with an already implanted CardioMEMS device. intervention 2: Conventional, guideline-directed therapy for heart failure and reduced ejection fraction intervention 3: Conventional, guideline-directed therapy for heart failure and reduced ejection fraction in ACE-inhibitor intolerant patients intervention 4: Angiotensin-neprilysin inhibitor that is now FDA-approved and guideline-directed therapy for patients with symptomatic heart failure and reduced ejection fraction despite treatment with an ACE-inhibitor/Angiotensin-Receptor Blocker

PARENT Trial Pilot 
Pulmonary Artery Pressure Reduction with ENTresto (sacubitril/valsartan) 
 
Detailed Protocol  
Version 4.2 
This pilot study will compare the hemodynamic impact of approved drugs for heart failure (HF) 
on the elevated pulmonary artery pressures measured by an implanted monitoring device that is 
also approved for such patients.  Both the medications and the monitoring device will be used 
according to approved indications. The only aspects of the study that are not standard care will 
be the increased frequency of pressure measurement and clinical assessment schedule.  
I. 
BACKGROUND AND STUDY RATIONALE 
a. Background 
Almost 25 years ago, the CONSENSUS and SOLVD trails demonstrated a decrease in the 
mortality rate of patients with heart failure with reduced ejection fraction (HFrEF) on 
angiotensin-converting enzyme inhibitors (ACEi).1, 2 Since then, ACEi have been a cornerstone 
HFrEF treatment. They are included in every major set of guidelines for HFrEF management.3, 4 
Angiotensin receptor blockers (ARB’s, such as valsartan) have similarly been shown to decrease 
the mortality rate of patients with HFrEF for patients who could not tolerate ACEi therapy. 5, 6  
The Medication: The newest neurohormonal therapy approved for heart failure (August 2015) is 
sacubitril/valsartan (trade name Entresto).  This medication is the first of a new family of agents 
(ARNI = angiotensin receptor antagonist with neprolysin inhibitor), combining the approved 
angiotensin receptor blocker valsartan with sacubitril, an inhibitor of neprilysin, which is a 
neutral endopeptidase that degrades endogenous vasoactive peptides.7 ,8,9,10 Sacubitril increases 
circulating natriuretic peptides, which have been shown to facilitate natriuresis and vasodilation.  
Entresto reduces fluid retention and vasoconstriction that contribute to heart failure symptoms, 
and is also thought to decrease apoptosis and remodeling that lead to disease progression.11  
The Monitoring Device: Progress in HF management outside the hospital has included 
validation of a strategy of ongoing monitoring of pulmonary artery pressures every day from 
home via a monitor implanted in a distal pulmonary arteriole, the CardioMEMS device.  The 
information is transmitted to a website where it is reviewed by the HF team, who can intervene 
to adjust diuretics and other medications by phone to avert decompensation and re-
hospitalization.  The device received FDA approval in mid 2014, and is now being implanted in 
many cardiac catheterization laboratories, including at Brigham and Women’s Hospital. The 
pressure information is reviewed regularly by the HF management team who are in regular 
contact with the patient to aid in management decisions.

b. Previous Pre-Clinical or Clinical Studies  
The Medication: Entresto (sacubitril/valsartan) was first tested in hypertensive patients in 2010, 
compared to valsartan (an ARB) alone.12 In a study of over 1300 patients, Entresto reduced 
blood pressure more than the valsartan alone..12 In the PARADIGM-HF trial of  8442 patients, 
Entresto was shown to be superior to the ACEi enalapril, reducing the risk of death and 
hospitalization among patients with heart failure with reduced ejection fraction (HFrEF).13 The 
study was stopped early for overwhelming benefit after a median follow-up of 27 months, at 
which time  the hazard ratio for the primary outcome of death/HF hospitalization was 0.80 (95% 
CI 0.73-0.87) for patients randomized to Entresto, as compared to enalapril. The hazard ratio for 
reducing all cause mortality was 0.84.  These impressive results lead the FDA to grant priority 
review and full approval in August 2015. Entresto is now being used increasingly in the care of 
patients with HFrEF.  
The Monitoring Device: The CardioMEMS HF System, a wireless hemodynamic monitoring 
system has been shown to measure pulmonary artery pressures reliably over years.  The device 
was implanted in all patients in the randomized single-blind CHAMPION trial, which compared  
the management strategy using these pressures together with clinical information to guide 
therapy, compared to management based only on weight and symptoms in patients whose care 
team were not able to see the pressure information.  The device was associated with a 37% 
reduction in HF hospitalizations and a reduction in total hospitalizations, and the freedom from 
device-related complications was 98.6%.  As of May 2014 it was approved by the FDA for the 
management of HF in patients who had at least one hospitalization during the previous year for 
heart failure.14 Subsequent information published this year in Lancet demonstrated  a 48% 
reduction in hospitalization rate in the real-world setting  when the control patients crossed over 
to pressure management strategy.15 
c. Study Rationale 
The clinical benefits of Entresto are widely accepted, but there are many pathways through 
which these benefits may be derived.  The increase in circulating natriuretic peptides are 
considered to decrease myocardial apoptosis and ventricular remodeling and to oppose other 
systemic effects of adverse activation of the renin-angiotensin and sympathetic nervous systems.  
The natriuretic peptides also have direct hemodynamic effects on sodium and water excretion 
and on vascular tone.  These effects could lead to reduction in elevated pulmonary artery 
pressures, which are associated with many of the symptoms of HF and with the development of 
pulmonary hypertension which impairs right heart function and contributes to development of 
secondary right heart failure.   
This pilot study takes advantage of the availability of the home monitoring device for HF 
management, and will include only patients in whom this device has already been implanted for 
management according to clinical indications.  It will test the primary hypothesis that the

replacing ACEI/ARB therapy with Entresto will lower pulmonary artery pressure at 6 weeks 
compared to continuation of ACE inhibitor/ARB therapy and that that improvement will be 
sustained over the course of 20 additional weeks of therapy. In addition, the immediate first-dose 
response will be assessed on the first day of administration, with the hypothesis that the first dose 
will lead to immediate reduction in pulmonary artery pressures.  The durability of the effect will 
be assessed over the next 20 weeks during the longitudinal phase, with the hypothesis that early 
reductions in pulmonary artery pressure will be sustained.

Tertiary Objectives (Exploratory):  
• 
Examine the relationship of change in PAPm to change in the questions in the Kansas 
City Cardiomyopathy Questionnaire (KCCQ) 3, 7,8,9 which describe the severity of

*Will be 3 comparisons:  
1)  6 weeks of Entresto vs 6 weeks of continued ACEI/ARB (Group A compared to B at 6 weeks) 
2) Baseline on ACEI/ARB compared to 6 weeks on Entresto (Groups A and B combined) 
3) 12 weeks on Entresto compared to 32 weeks on Entresto in longitudinal study (all pts)\ 
 
II. STUDY DESIGN 
The study is a randomized, active comparator study of the hemodynamic effects of Entresto vs. 
ACEi/ARB as measured by an implantable hemodynamic monitor. Formal blinding is not 
possible due to the lack of placebos available to match all potential ACE inhibitors and ARBs, 
but every effort will be made to mask the specific drug assignment from the patients to limit bias. 
For safety reasons, physicians will not be blinded to study drug assignment.

IV. 
SUBJECT ENROLLMENT  
 
a. Identification of Patients and Consent 
The investigators and study staff will screen the outpatient cardiology clinic rosters to identify 
eligible subjects. If a subject is eligible, the investigator and/or study staff member will follow 
Partners Human Research Committee (PHRC) guidelines on recruitment. Permission to approach 
a potential subject will be obtained from the attending physician who will gain permission from 
the potential subject before a study staff member proceeds to introduce the study.  
A licensed physician investigator will obtain written informed consent from subjects after all 
aspects of the study have been discussed and the potential subject has agreed to participate in the 
study. Sufficient time will be allowed for the potential subject to review the consent form. All 
questions will be answered by the investigator before the consent form is signed. Contact 
information will be given to the potential subject so that he or she may contact the study 
physician or staff with any questions or concerns. 
When a potential subject is the investigator’s own patient, every effort will be made to have an 
investigator other than the patient’s physician obtain informed consent. It will be made clear to 
the potential subject that participation in the study is entirely voluntary and that their decision 
will not affect their care now or in the future.  
 
b. Treatment Assignment and Randomization 
Randomized codes designating treatment group assignment will be generated for each patient. 
After informed consent is obtained, study personnel will obtain assigned to treatment group A or 
B based on the relevant randomization code.     
Three study drugs will be utilized during the study: 
 
Study Drug A = Masked Placebo, dosed twice daily 
 
Study Drug B = Masked Active Entresto 
 
Study Drug C = Masked Active Entresto 
Group A will receive Study Drug A + Study Drug B for weeks 1-6 , Study drug A + Study Drug 
C for weeks 6-12,  and then open-label Entresto only for weeks 13-32.  
Group B will receive Study drug A + their previous ACEi/ARB for weeks 1-6,  and then, after a 
2 day (minimum 36 hours as per FDA labelling) washout period, switch to Study Drug A + 
Study Drug C for weeks 7-12. This group will then receive open-label Entresto only for weeks 
13-32 (as with Group A).

Entresto dosing 
Entresto (valsartan/sacubitril) will be given to patients during the study. This FDA approved 
drug is currently available in three doses: 24/26 mg, 49/51 mg, and 97/103 mg (equivalent to 50 
mg, 100 mg, and 200 mg of LCZ696). Entresto is dosed twice a day. Patients will initially be 
transitioned to a dose of Entresto that is based on their previous ACEi/ARB dose using the 
dosing conversion algorithm19 provided by the manufacter (see table below):

Method  
Entresto is only available orally.  
Schedule of Administration 
Entresto is administered twice a day. On day 5 and day 47, patients will be instructed to hold 
their other morning medications and take only their first dose of Entresto and placebo or 
ACEi/ARB and placebo. They will then be asked to measure their PA pressures using their home 
CardioMEMS device 1, 2, and 3 hours after their first dose of Entresto or ACEi/ARB.  
Both groups will do this on day 5 and day 47. On day 5, Group A will be measuring the first 
dose effect of Entresto and Group B will be measuring the first dose effect of ACEi/ARB after 
the washout period. On day 47, Group A will be measuring the acute effects of Entresto after 6 
weeks of therapy and Group B will be measuring the first dose effects of Entresto.  
Patients will also be asked to complete this “acute PA pressure measurement” schedule, i.e. 
holding morning medications, measuring PA pressure before and at hours 1, 2, 3 after their 
morning dose of Entresto or ACEi/ARB, after any dosing change.  
On all other days, patients will take their morning dose of Entresto or ACEi/ARNB and placebo 
with their other morning medications. The evening dose of Entresto or ACEi/ARB and placebo 
can be taken with other evening medications as well.  
Dose Modifications 
At each clinic visit, if clinically indicated, the dose of Entresto and/or ACEi/ARB will be 
uptitrated if possible, per standard clinical protocol depending on blood pressure and tolerability. 
The goal dose of Entresto for all patients will be 97/103 mg BID (dose studied in the trials). 
ACE-inhibitors and ARBs will be titrated to the effective target doses prescribed by clinical 
guidelines. fter each medication dose change (of either Entresto or ACEi/ARB) the patients will 


05.31.2017 
 
10 
 
be asked to measure “acute PA pressures” at home (see above regimen) and have safety labs will 
be checked within 2 weeks of the dosing change. Patients will be called by a study nurse 2-3 
days after any dosing changes to assess for any side effects. 
 Toxicities  
In this study, we will be supplying patients Entresto, a chronic heart failure medication which 
has been proven efficacious in large, randomized clinical research trials. After any dosing 
changes, of either Entresto or ACEi/ARB, for the first administration of the new dose, patients 
will hold their other medications, measure their PA pressures before medication administration 
and then every hour for 3 hours after the new dose. Patients will be called by a study nurse 2-3 
days after any dosing changes to assess for any side effects.  
During the ACEi/ARB “washout periods,” all patients will have 24/7 access to study staff and/or 
study physicians to report any new symptoms or ask questions.  
Similar to ACEi therapy, Entresto has a small risk of angioedema (0.2% in the Entresto group 
compared to 0.1% in the ACEi group in the PARADIGM trial, with no incidence of upper 
airway obstruction).  To eliminate any increased risk of angioedema from prior ACEi or ARB 
exposure in this study, all patients will undergo a mandatory 2 day (minimum 36 hours as per 
FDA labelling)  washout period between any administration of these medications and  Entresto 
administration.  This is consistent with prior clinical trials and the standard of care as would be 
practiced for any patient switching from ACEi to Entresto, regardless of whether or not they 
were enrolled in this study. 
c. Devices to be Used  
Only HF patients with previously implanted CardioMEMS devices will be eligible for 
enrollment. The CardioMEMS device has been studied extensively in previously clinical trials 
and shown to be both effective and safe, decreasing HF hospitalization by 37%, with freedom 
from device-related or system-related complication rate of 98.6%.14  The FDA approved the 
CardioMEMS device on May 28, 2014 for patients with NYHA III heart failure who have been 
hospitalized for heart failure within the previous year. Once the device is implanted, patients are 
set up with a home monitoring system and instructed to transmit their PA pressures daily. They 
record and transmit their pulmonary artery pressures non-invasively by laying on a special pillow 
connected to a home recording and transmission consol. Each recording requires that the patient 
lay still for approximately 18 seconds. The PA pressure measurement is automatically and 
electronically transmitted to a trained HF nurse who checks the recording for accuracy and 
reliability. If the recording is not acceptable, the monitoring nurse will call the patient and ask 
that the recording be repeated. The recording and transmission process is quick and completely 
painless. The PA pressure measurement and waveforms are visible to the monitoring nurse and 
the clinical team, but not to the patients.  


05.31.2017 
 
11 
 
Each CardioMEMS recording provides a PA systolic (PAPs), diastolic (PAPd) and mean 
(PAPm) pressure as well as the tracings. These measurements and their trend over time are 
reviewed by the patient’s heart failure team. Medications and other therapies are adjusted based 
on these trends. Patients are called every few days to review their trends and discuss medication 
changes. If a patient has an acute change in their measurements, they are called as part of 
standard clinical care the next business day to assess their clinical status and potential changes in 
therapy.   
Patients will continue their regular, daily monitoring schedule just as before the trial. The only 
change will be additional PA pressure measurements will be “acute PAP measurements” before 
and at hours 1,2,3 after Entresto/ACEi/ARB on day 5 and 47. Patients will also be asked to 
measure their PA pressure on day 5 and 47 in the evening, before they take their evening dose of 
Entresto/ACEi/ARB.  
“Acute PA pressure measurements” will also be obtained on the first day of any new dosing 
regimen (after any dosing changes) for safety.   
PA pressure measurements before and at 5 minute intervals for 30 minutes after the 6 minute 
walk test will be performed by the study staff in the clinic setting.   
PA pressure measurements before and at 5 minute intervals for 30 minutes after the double 
Master’s Step test will be performed by the study staff in the clinic setting.   
PA pressure and blood pressure measurements before, during the Handgrip test (with 30 seconds 
intervals during the 2-minute test) and at 5 minutes intervals for 15 minutes of recovery will be 
performed by the study staff in the clinic setting. Heart rate is going to be recorded throughout 
test and recovery. 
PA pressure and blood pressure measurements before, during the Stroop Color test (with 30 
seconds intervals during the 3-minute test) and at 5 minutes intervals for 15 minutes of recovery 
will be performed by the study staff in the clinic setting. Heart rate is going to be recorded 
throughout test and recovery.

Pulmonary pressure monitoring transmitted from home: 
Patients will transmit pressures every morning before taking medications.  Specific case report 
data entry in addition to the clinic measurements and first dose time points at home will include 
PA pressures every Monday and Thursday and daily for 5 days following any change in study 
drug or in other heart failure medications.  All transmitted pressure information remains 
available on the CardioMEMS website so can be retrieved at any time if other questions arise 
about trends from pressure transmitted on other days.

2) Baseline on ACEI/ARB compared to 6 weeks on Entresto (Groups A and B combined) 
3) 12 weeks on Entresto compared to 32 weeks on Entresto in longitudinal study (all pts) 
 
Statistical Analysis  
Co-Primary Endpoints:  
Intensive Phase:  
• Determine the difference between mean change in mean pulmonary artery pressure 
(PAPm) after 6 weeks on Entresto compared to 6 weeks on continued ACEi/ARB  
o Statistical Plan: These changes from baseline to 6 weeks constitute continuous 
data. Therefore, the distribution of average changes in PAPm from baseline to 6 
weeks will be assessed in Group A and Group B. If both distributions are normal, 
t-testing will be performed to compare the mean changes between groups. If the 
distributions are not normal, Wilcoxon testing will be used. P <0.05 will be 
significant. 
 
Acute First-Day Response  
• Determine the change in PAPm between baseline and first 3 hours after the first dose of 
Entresto  
o Statistical Plan: These changes in PAPm from baseline to 2 hours after Entresto 
constitute a distribution of continuous data. The distribution of change in PAPm 
from the morning baseline visit (before Entresto) to 2 hours after the first dose of 
Entresto will be assessed in both groups. The distribution of changes will be 
assessed for normality. If the distributions are normal, the results will be 
presented as means with standard errors. If the distributions are not normal, the 
results will be presented as medians with interquartile ranges.  
 
Secondary Endpoints:  
• Determine the mean change in PAPm in both groups on Entresto from week 12 to week 
32 in longitudinal study 
o Statistical Plan: The changes in PAPm from week 12 to week 32 constitute 
continuous data. The distribution of average change in PAPm from week 8 to 
week 32 will be assessed in both group A and B. The distribution of changes in 


05.31.2017 
 
58 
 
PAPm will be assessed for normality. If the distributions are normal, the results 
will be presented as means with standard errors. If the distributions are not 
normal, the results will be presented as medians with interquartile ranges.  
 
• Determine the difference between mean change in PAPm from baseline on  ACEI/ARB to 
6 weeks on Entresto (Groups A and B) 
o Statistical Plan: The distribution of the average change in PAPm from baseline to 
6 weeks will be assessed in Group A and combined with the distribution of 
change in PAPm from week 6 to week 12 in Group B. The combined distributions 
will be assessed for normality. If the combined distribution of changes in PAPm is 
normal, the results will be presented as means with standard errors. If the 
distributions are not normal, the results will be presented as medians with 
interquartile ranges.  
 
• Determine the impact of therapy over time on standard 6 minute walk test, assessing  
distance walked and changes in PAPm during recovery after the walk.  
o Statistical Plan: These changes in distance walked from baseline to 6 weeks 
constitute continuous data. Therefore, the distribution of average changes in 
PAPm from baseline to 6 weeks will be assessed in Group A and Group B. If both 
distributions are normal, t-testing will be performed to compare the mean changes 
between groups. If the distributions are not normal, Wilcoxon testing will be used.

after 6 weeks of Entresto- Group A: week 6 minus baseline; Group B: week 12 
minus week 6): The change in PAPm from pre to peak exercise at baseline and at 
5 minute intervals for 30 minutes of recovery will be compared to the change in 
PAPm from pre to peak exercise and at 5 minute intervals for 30 minutes of 
recovery at 6 weeks in Group A.  If the distributions are normal, the results will 
be presented as means with standard errors. If the distributions are not normal, the 
results will be presented as medians with interquartile ranges. The change in 
PAPm from pre to peak exercise at 6 weeks and at 5 minute intervals for 30 
minutes of recovery will be compared to the change in PAPm from pre to peak 
exercise and at 5 minute intervals for 30 minutes of recovery at week 12 in Group 
B.  If the distributions are normal, the results will be presented as means with 
standard errors. If the distributions are not normal, the results will be presented as

Power Analysis 
There will be 20 patients total, 10 in each group.  


05.31.2017 
 
64 
 
Between group comparison: This sample size will provide 90% power with 2-sided alpha of 0.05 
to detect a 20% difference between the 2 groups (Entresto and ACEI/ARB) in the PAPm change 
at 6 weeks, based on an assumed baseline PAPm of 25 mm, using a t-test with a standard 
deviation in the mean change of as high as 3.4. We do not yet have data on which to estimate the 
standard deviation of this change, but we have found a standard deviation of 3-4 mm Hg of 
PAPm pressures during 5 day periods in stable patients followed on Cardiomems devices at 
Brigham and Women’s Hospital (unpublished data).  
All patients after 6 weeks of Entresto compared to chronic ACEI/ARB at baseline: There is 
additional power for this highest secondary endpoint.  Assuming the PAPm baseline on 
ACEI/ARB mean of 25mm,  a sample size of 20 patients will provide 90% power with two-sided 
alpha of 0.05 paired t-test to detect a 20% decrease (to PAPm of 20 mm) after 6 weeks of 
Entresto, with a standard deviation for the change as high as 6.8.   
 
VII. 
RISKS AND DISCOMFORTS 
 
Complications from Surgical and Non-Surgical Procedures : Not applicable to this study. There 
are no surgical and non-surgical procedures.  
 
a. Although all patients are eligible for open-label Entresto at randomization, those randomized 
to group B  will  be initiated 6 weeks later than those in group A. This may delay access to 
the potential incremental benefits of Entresto; however, there is currently a wide variation of 
practice in initiation of Entresto.  This is partly relatd to cost and partly to concern for how 
best to titrate this agent in the setting of diuretics and beta blocking agents that the patient 
will continue to take.   
 
b. Drug Side Effects and Toxicities 
Subjects are not exposed to any risks other than those occurring during standard  approved care 
for HFrEF, which includes both the medication Entresto and the CardioMEMS monitoring 
device. The only way in which their enrollment in the study differs from standard of care is that 
they will undergo more frequent monitoring, which increases the safety of drug titration to avoid  
lowering of filling pressures to levels that might be associated with postural hypotension when  
Entresto is added to their previous HF regimen.  
It is unlikely that there will be any adverse effects of holding ACEI/ARB for 2 days (minimum 
36 hours as per FDA labelling) at the beginning of the study. For the A group, this would occur 
anyway for safety, as a washout period of at least 2 days (minimum 36 hours as per FDA 
labelling) is required before initiation of Entresto.  For the B group who will resume ACEI/ARB 
after 2 days (minimum 36 hours as per FDA labelling), such pauses in one component of therapy 


05.31.2017 
 
65 
 
are common around the time of surgery and are not anticipated to lead to any symptoms, as the 
other medications will be continued as usual.    
Common: Based on Novartis’ published prescribing guidelines for Entresto and previous clinical 
trials, the major side effects are similar to ACEi/ARB therapy: hypotension, hyperkalemia and 
renal dysfunction. All of these potential side effects will all be monitored for by study staff with 
frequent lab work, as is standard of care. In addition, due to their enrollment in this trial, 
hemodynamic assessment (including blood pressure) will be checked at each visit and PA 
pressures will be monitored daily by patient and reviewed by the study staff. This will increase 
the patient’s level of safety as compared to standard clinical practice. Any dose changes will be 
followed by “acute PAP measurements” the next day and safety lab work as clinically indicated.  
Uncommon: Similar to ACEi therapy, Entresto has a small risk of angioedema (0.2% in the 
Entresto group compared to 0.1% in the Enalapril group in the PARADIGM trial). These events 
have to date not been known to cause airway compromise.  
To eliminate any increased risk of angioedema from prior ACEi exposure in this study, all 
patients will undergo a mandatory 2 day (minimum 36 hours as per FDA labelling) washout 
period between any ACEi administration and any Entresto administration. This is consistent with 
prior clinical trials as well as the standard of care and for any patient switching from ACEi to 
Entresto, regardless of whether or not they were enrolled in this study.  
If a patient has an adverse reaction to any drug in the study (ACEi, ARB or Entresto) that cannot 
be ameliorated with dose reduction or adjustment, the medication will be stopped. No patients 
will be “removed” from the study. Even if a patient experiences symptoms that require cessation 
of the medication, we will continue to monitor them for the duration of the study. 
 
c. Device Complications/Malfunctions 
Subjects are not exposed to any risks from their monitoring device other than those consistent 
with the standard of care for HFrEF. All of the patients enrolled in this study already have 
CardioMEMS devices in place for clinical indications. Therefore, they incur no additional risk 
from the CardioMEMS device by enrolling in this study. There is essentially no risk from 
making pressure measurements and transmitting them to a central server.  
d. Psychological (Non-Medical) Risks    
Common: There are no expected, common psychological risks to the patients in this study. 
Patients undergoing pulmonary pressure monitoring at home generally feel reassured by regular 
transmission of data to a health care team. Monitoring in this study will be even more frequent 
and intensive than normal care, which may be even more reassuring to the patient.  Uncommon: 
There are no expected, uncommon psychological risks to the patient from participation in this 


05.31.2017 
 
66 
 
study. If a patient experiences any new psychological symptoms during the course of this study, 
he/she will be referred, as per standard care, to the appropriate psychological and/or psychiatric 
resources.  
e. Radiation Risks  
This is not applicable to this study since patients are not exposed to radiation during this study. 
No statement from the Radiation Safety Committee is necessary.  
 
VIII. POTENTIAL BENEFITS 
 
a. Potential Benefits to Participating Individuals  
The subjects enrolled in this study will receive Entresto at no cost. This medication decreases 
both HFrEF mortality and hospital readmission rates.. Patients enrolled in this study will be 
provided with Entresto for the duration of the study (Group A 32 weeks, Group B 26 weeks).  At 
the conclusion of the trial, subjects can discuss receiving Entresto as part of their heart failure 
medical therapy with their physician. It is likely that the information gained from monitoring 
PAP will allow earlier identification of a need for adjustment in a concomitant medication. This 
could lead to lower incidence of reversible side effects such as hypotension and renal 
dysfunction. As compensation for patient time and effort, the study will provide $25/visit for 
each of the 8 required clinic visits during this study. This will cover both the cost of parking ($10 
for up to 4 hours in the BWH patient parking lot) and the cost of a meal at the hospital. 
 
 
b. Potential Benefits to Society  
It is hoped that this study will help the medical community to better understand what effect, if 
any, Entresto has on pulmonary pressures. It is hoped that this information will allow physicians 
to better select the right doses and to adjust other medications with Entresto for greater benefit  
and safety.  If, as anticipated,  Entresto is shown to cause a sustained decrease in PA pressures, a 
further trial can be designed to determine if and how it could delay or prevent the development 
of secondary right-sided heart failure, which often heralds irreversible decompensation for 
patients with reduced left ventricular ejection fraction.

SAFETY MONITORING AND REPORTING 
 
a. Independent Monitoring of Source Data

Trained research assistants will be responsible for inputting the data into the locked study 
database. The study’s project coordinator will then be responsible for verifying key baseline data 
within one week of enrollment for each patient enrolled. The project coordinator will also review 
the study data on a monthly basis thereafter for accuracy. The study database will be checked 
monthly using random audits of ~10% of subjects for data for missing, out-of-range, or 
inconsistent values.   
 
b. Safety Monitoring 
Due to the fact that we are using an FDA approved drug for its FDA approved indication and a 
previously-placed FDA approved device for its FDA approved indication, we will not have a 
formal Data Safety Monitoring Board. Nevertheless, we will take all necessary steps to ensure 
the safety of our patients and the validity of the results.  
All of the study data will be stored on a Partners desktop computer housed in a locked office in 
the Advanced Heart Failure section of Building A at BWH. A dedicated and trained data entry 
research assistant will enter all initial demographic data within 2 days of a patient’s enrollment in 
the study into a secure, password protected database. A study coordinator will verify the 
accuracy of the information on a regular basis to check for accuracy.  
Subsequent clinical information obtained during the course of the study, will be entered into the 
password-protected database by a trained research assistant per standard protocol and a study 
coordinator will review the accuracy of this information as well. The investigators will review all 
safety and data management policies and procedures with new staff and annually with current 
staff. 
This study will have an independent reviewer (licensed cardiologist who practices outside of the 
Partners System and has no involvement with or relation to the study) to review, in a de-
identified fashion, any/all potential adverse events and determining if they are appropriate to 
report to Novartis and the Partners IRB.  
c. Outcome Monitoring 
This study will have an independent reviewer (licensed cardiologist who practices outside of the 
Partners System and has no involvement with or relation to the study) to review both results of 
the study. The independent reviewer for this study will be:  
 
Robb D. Kociol, MD 
Beth Israel Deaconess Medical Center.  
Director of the Ventricular Assist Device Program 
Associate Director of Advanced Heart Failure 
 
Dr. Kociol is a heart failure specialist outside the Partners system who is experienced in both the 
clinical care of heart failure patients and in clinical investigation, having participated in clinical

events adjudication, patient recruitment, and Data Safety Monitoring Committee roles for a 
number of cardiovascular device and pharmaceutical trials. He is an active clinical member of 
the Cardiovascular Division and the Associate Director of the Advanced Heart Failure Program 
at Beth Israel Deaconess Medical Center. In addition, he is currently a member of the Clinical 
Events Committee for the Harvard Clinical Research Institute in Boston, MA as well as a 
member of the Data Safety Monitoring Committee for a clinical trial of esmolol in severe sepsis.  
 
Specifically, Dr. Kociol will review all endpoint data including PA pressures (daily trends, 
acute/first dose/dose change PA pressures, exercise recovery PA pressures) hemodynamic and 
side effect information obtained in clinic, 6-minute walk test, double Master’s step test, Handgrip 
test, Stroop Color test, laboratory work, KCCQ scores and medication dose changes. He will be 
blinded to the study group assignment and will  review this data in a de-identified fashion. He 
will also be responsible for reviewing any/all potential adverse events and determining if they are 
appropriate to report to Novartis and the Partners IRB. He will review all clinical and safety data 
after every 5 patients have been enrolled. Potential adverse events will be reviewed as soon as 
possible if/when they occur. The study will have a pre-specified stopping guideline of p<0.01 for 
harm on any safety outcomes. 
 
d. Adverse Event Reporting Guidelines 
All of the following events will be collected for review by the independent reviewer and reported 
to Novartis Pharmaceuticals (along with the relevant randomization codes): All serious adverse 
events (SAE), all reports of drug exposure during pregnancy, all non-serious adverse events, all 
reports of misuse and abuse of the study drug, other medication errors, and uses outside what is 
foreseen in the protocol (irrespective of  whether a clinical event has occurred). Any member of 
the study team can report a potential adverse event. Since Entresto is an FDA approved drug and 
it will be using it for its FDA approved indication, any adverse events thought to be related to 
Entresto will be reported FDA’s MedWatch program, in keeping with standard practice. Given 
the mechanism of action of the drug, angioedema is an event of special interest, and all 
angioedema-like events will be submitted for independent review. Any adverse events that are 
deemed “significant” by the independent reviewer will also be reported to the Partners IRB.  
 
An SAE is defined as any adverse event (appearance of or worsening of any pre-existing) 
undesirable sign(s), symptom(s) or medical conditions(s) which meets any one of the following 
criteria: 
• 
is fatal or life-threatening 
• 
results in persistent or significant disability/incapacity 
• 
constitutes a congenital anomaly/birth defect 
• 
requires inpatient hospitalization or prolongation of existing hospitalization, unless 
hospitalization is for: 


05.31.2017 
 
69 
 
• 
routine treatment or monitoring of the studied indication, not associated with any 
deterioration in condition (specify what this includes) 
• 
elective or pre-planned treatment for a pre-existing condition that is unrelated to the 
indication under study and has not worsened since signing the informed consent 
• 
treatment on an emergency outpatient basis for an event not fulfilling any of the 
definitions of a SAE given above and not resulting in hospital admission 
• 
social reasons and respite care in the absence of any deterioration in the patient’s 
general condition 
• 
is medically significant, i.e. defined as an event that jeopardizes the patient or may 
require medical or surgical intervention. 
 
All malignant neoplasms will be assessed as serious under “medically significant” if other 
seriousness criteria are not met. 
Life-threatening in the context of a SAE refers to a reaction in which the patient was at risk of 
death at the time of the reaction; it does not refer to a reaction that hypothetically might have 
caused death if more severe.
