Introduction
1.1
Background
Heart failure (HF) is a terminal condition of all heart diseases, characterized by worsening of 
symptoms such as exertional dyspnea and/or breathlessness requiring repeated hospitalization 
that lead to premature death, as well as significantly greater risks of sudden death 
(Ponikowski et al 2016). The mortality within 5 years after diagnosis is approximately 50% in 
Europe and the United States (US) (Yancy et al 2013); this rate is similar to the 5-year mortality 
in all patients with cancer. In Japan, a cohort study of chronic heart failure (CHF) Analysis and 
Registry in the Tohoku District (CHART)-2 (Shiba et al 2011) showed that the total annual 
mortality was 4.2% and the rate of hospital readmission for HF was 14.3% among Japanese 
CHF patients classified into Stage C (symptomatic HF) or Stage D (refractory HF) according 
to the American College of Cardiology (ACC)/American Heart Association (AHA) criteria. 
These indicated that the prognosis of CHF patients in Japan was as poor as that of CHF patients 
in Europe and US (Shiba and Shimokawa 2011, Sakata and Shimokawa 2013).
In recent years, the number of patients with HF has rapidly increased due to increased 
prevalence of ischemic cardiac diseases, outcome improvement of those acute treatment, and 
population aging, etc., and estimated at approximately 26 million across the world 
(Ambrosy et al 2014). In Japan, the number of patients with HF is currently approximately 1 
million, estimated to reach 1.3 million in 2030 (Okura et al 2008). According to the Japanese 
Registry of All cardiac and vascular Diseases (JROAD) conducted by the Japanese Circulation 
Society (JCS), the number of hospitalized patients with HF for FY2017 was 260,157, which 
have increased yearly (The Japanese Registry Of All cardiac and vascular Diseases (JROAD)). 
Frequent hospitalization not only adds physical, mental, and economic pressures on the patients 
and their families, but also imposes an enormous burden on health care financing.
In a part of patients with HF, it has been shown to occur with normal systolic function. HF with 
normal or “near-normal” ejection fraction (EF) has been designated HF with preserved ejection 
fraction (HFpEF). HFpEF accounts for approximately half of HF cases, and is associated with 
substantial morbidity and mortality (Lam et al 2011). Moreover, the prevalence of HFpEF, as 
well as its relative prevalence compared with HF with reduced ejection fraction (HFrEF), has 
been increasing in recent years (Owan et al 2006, Shiba and Shimokawa 2011). Increasing 
prevalence of HFpEF may be a consequence of growing aging population, and increases in 
hypertension (HTN) and obesity (Blanche et al 2010).
HFpEF is a serious condition associated with substantial morbidity. Hospitalization for
worsening HF is common (Lewis et al 2007, Hoekstra et al 2011) and large prospective 
registries have shown re-hospitalization rates for HFpEF to be high and similar to those of 
HFrEF (Lenzen et al 2004, Fonarow et al 2007, Tsuchihashi-Makaya et al 2009). The high rate 
of hospitalization for heart failure associated with HFpEF is a marker of disease progression 
and poor outcomes (including death) in patients (Solomon et al 2007, Ahmed et al 2008) . 
Finally, survival rates have not improved over time for HFpEF, unlike for HFrEF 
(Owan et al 2006).
Unlike HFrEF, no treatment has shown to reduce morbidity or mortality in patients with HFpEF. 
There is currently no approved therapy for the treatment of HFpEF. Previous therapies tested 
in patients with HFpEF mainly focused on blocking/inhibiting the detrimental effects of 

Novartis

Protocol No. CLCZ696D1301E1
neurohormonal activation (i.e. angiotensin converting enzyme inhibitor (ACEIs), angiotensin 
receptor blocker (ARBs), mineralocorticoid antagonist (MRAs)), and largely ignored the 
physiological compensatory effect of the natriuretic peptide (NP) system. These agents failed 
to demonstrate outcome benefits in this patient population. The current focus of treatment is to 
alleviate symptoms and improve well-being. Consequently, the guidelines from the ACC/AHA 
(Yancy et al 2017) and European Society of Cardiology (ESC) (Ponikowski et al 2016) 
recommend treating volume overload/symptoms with diuretics and treating comorbid 
conditions that are common in HFpEF, such as diabetes mellitus (DM), HTN, renal impairment, 
atrial fibrillation (AF) and coronary artery disease (CAD) as well as Japan 
(Guidelines for Diagnosis and Treatment of Acute and Chronic Heart Failure). Addressing this 
need is of utmost importance given the high morbidity and mortality of patients with HFpEF 
and the consequent stress on the global health care system (Sharma and Kass 2014).
LCZ696 (sacubitril/valsartan) is a first-in-class, angiotensin receptor neprilysin inhibitor 
(ARNI), approved in more than 100 countries worldwide for the treatment of adult patients with 
heart failure and reduced ejection fraction (HFrEF).
LCZ696, through its dual mode of action, potentiates NPs via neprilysin (NEP) inhibition while 
inhibiting the renin angiotensin system (RAS) via angiotensin type 1 (AT1) receptor blockade; 
mechanisms which are considered to act in a complementary and at least additive manner. The 
mechanism of action (MoA) of LCZ696 suggests that it may impact the suspected 
pathophysiology of HFpEF, in which it is believed that excessive fibrosis and myocyte 
hypertrophy lead to abnormal left ventricular diastolic filling, impaired diastolic distensibility 
and/or increased vascular stiffness, with consequent elevated cardiac filling pressures 
(Krum and Abraham 2009).
CLCZ696B2214 (PARAMOUNT) was a phase II randomized, double-blind, active-controlled 
therapeutic validation trial in HFpEF patients (Solomon et al 2012). The study evaluates 
LCZ696 against the active comparator valsartan. The primary endpoint was change in 
N- terminal pro-brain natriuretic peptide (NT- proBNP) at 12 weeks. It has been shown that a 
decrease in NT- proBNP is correlated with reductions in left ventricular wall stress and is 
correlated with changes in central hemodynamics (Kazanegra et al 2001, Forfia et al 2005, 
Chow et al 2011, , ).
LCZ696 is the first agent with positive Phase II data in HFpEF, demonstrating significantly 
reduced NT- proBNP, improvement with left atrial reverse remodeling and improvement in 
New York Heart Association (NYHA) class. The results of PARAMOUNT in HFpEF 
emphasize the therapeutic rationale of targeting both neurohormonal systems through 
simultaneous inhibition of neprilysin and blockade of angiotensin II receptor type 1. Therefore, 
the phase III outcomes trial PARAGON-HF has started to evaluate the effect of LCZ696 on 
morbidity and mortality in HFpEF patients.
CLCZ696D2301 (PARAGON-HF) is the largest HFpEF trial ever conducted with 4,822 
patients from 43 countries worldwide including 79 patients from Japan. The study is ongoing 
and evaluates LCZ696 against the active comparator valsartan. The primary endpoint is a 
composite of cardiovascular (CV) death and total (first and recurrent) HF hospitalizations. 
Patients will be followed until 1,847 primary composite events have occurred or at least 26 
months, whichever occurs last. The study has so far undergone multiple safety reviews by an

independent Data Monitoring Committee (DMC) which has recommended continuing the study 
without protocol modifications.
LCZ696 is the only product known to be in late stage clinical development that leverages 
beneficial effects of the endogenous NP system, while simultaneously limiting the detrimental 
effects of prolonged RAS activation, to provide complimentary dual effects of NEP inhibition 
and RAS blockade to HFpEF patients.
1.2
Purpose
The purpose of this open-label study is to further evaluate the safety and tolerability of long-
term treatment with LCZ696 for the eligible Japanese patients who completed CLCZ696D2301 
(PARAGON-HF) until marketed product is available in Japan or 2 years from the date of the 
first patient enrolled in the open label extension study, whichever occurs first.

Study design
This study is an open-label extension study to the PARAGON-HF. Patients who completed the 
PARAGON-HF are eligible to participate. During the study, open-label LCZ696 will be taken 
in addition to background treatments of comorbidities in place of ACEIs, ARBs, and renin 
inhibitors.
At the first visit of the study (Visit 1), all patients willing to participate will provide informed 
consent and will provide blood samples for local lab assessment of their health status and their 
eligibility for the study will be evaluated by the investigator. The patients can be enrolled at the 
same day as the last visit of PARAGON-HF, or enrolled up to about 6 months after the result 
of PARAGON-HF is known at the latest. If the first visit of the study (Visit 1) is the same as 
the last visit of PARAGON-HF, the procedure of blood samples will not be required and the 
data of the last visit of PARAGON-HF can be used as the data at Visit 1. The study treatment 
will be dispensed upon confirmation of eligibility.
Patients will start on open-label LCZ696 at a dose that is equivalent to the last dose level (or 
dose of other renin angiotensin aldosterone syste (RAAS) inhibitors if patient switched) taken 
at the time of completing PARAGON-HF, but no higher than dose level 2 (Figure 3-1, 
Table 3-1). The dose and regimen of background treatment medications should be maintained.

Every attempt should be made to up-titrate and maintain the patient at the maximum tolerated 
LCZ696 dose with a target dose of 200 mg b.i.d. as soon as possible per the investigator’s 
medical judgement taking into account AEs including potassium level, kidney function, blood 
pressure (referred to Section 16.3 Appendix 3, Section 16.4 Appendix 4, and Section 16.5
Appendix 5).
At Visit 102 (Week 2-4), patients who tolerate open-label LCZ696 should be up-titrated to the 
next higher dose level by investigator judgement. If in the investigator's judgement, the patient 
does not tolerate the treatment dose level, then investigator should try to modify background 
medication in line with Section 6.5.1 in order to re-challenge the patient with a higher dose level 
at the earliest possible opportunity. Treatment guidelines for hyperkalemia, management of BP 
and renal dysfunction are provided in Section 16.3 Appendix 3, Section 16.4 Appendix 4, and 
Section 16.5 Appendix 5.
The patient will continue to receive LCZ696 until it is commercially available, or for a period 
up to 24 months from the first patient enrolled in this study, whichever comes first. If the 
primary endpoint of PARAGON-HF is not met, the study will be terminated.

Rationale
The purpose of this extension study is to assess the safety and tolerability of long-term treatment 
with LCZ696 in Japanese HFpEF patients who completed PARAGON-HF trial. This study 
allows the option of use of LCZ696 in patients benefiting from the study treatment in 
PARAGON-HF by the investigator judgement. 
The mechanism of action of LCZ696 suggests that it may impact the suspected pathophysiology 
of HFpEF, in which it is believed that excessive fibrosis and myocyte hypertrophy lead to 
abnormal left ventricular diastolic filling, impaired diastolic distensibility and/or increased 
vascular stiffness, with consequent elevated cardiac filling pressures. In phase II proof of 
concept trial in HFpEF (PARAMOUNT), LCZ696 demonstrated greater reductions in NT-
proBNP and all echocardiographic measures of left atrial size compared with valsartan. Albeit 
for HFrEF patients, LCZ696 showed a large benefit in morbidity and mortality compared to 
enalapril, standard therapy in the guideline in phase III outcome study (PARADIGM-HF). 
The rationale for allowing patients the option to receive open-label LCZ696 in this study 
pending release of the PARAGON-HF study results is twofold. First, if the treatment plan is 
implemented for a patient by the treating physician, it will minimize treatment disruption in 
post-PARAGON-HF treatment. PARAGON-HF patients were randomized to either valsartan 
or LCZ696 (sacubitril/valsartan), which are all components of LCZ696. As of the date of this 
study, the independent DMC has reviewed the cumulative safety data of the PARAGON-HF 
study twice annually since its initiation (total of eight safety reviews) and has determined that 
LCZ696 continues to demonstrate an acceptable safety profile relative to valsartan. Another 
rationale for allowing PARAGON-HF patients to be offered open-label LCZ696 before release 
of the PARAGON-HF study results is that there is currently no approved treatment for patients 
with HFpEF in Japan. Allowing investigators and patients the option to receive open-label 
LCZ696 in this study will afford them a treatment option that will minimize disruption in their 
medical regimen. If the results of PARAGON-HF does not show the efficacy, the study will be 
terminated.

4.1
Rationale for study design
An open-label study design was adopted for this study because it satisfies the main objective of 
obtaining safety and tolerability data of long-term treatment with LCZ696 in the Japanese 
HFpEF patients who completed PARAGON-HF. As there is no comparator in this extension 
study, study blinding is not necessary.
4.2
Rationale for dose/regimen and duration of treatment
The starting dose in this study was set based on the dose level administered in PARAGON-HF. 
The patients receiving study drug at dose level 3 in PARAGON-HF should start taking a 
LCZ696 at the next lower dose level to ensure patient's safety. The patients receiving study drug 
at dose level 2 in PARAGON-HF can start taking a LCZ696 at either the same dose level or the 
next lower dose level to ensure the patient’s safety based on the investigator's clinical judgement.
In case of the patients starting at the next lower dose level from PARAGON-HF, the dosage 
will be up-titrated to the next higher dose level (original dose level) as soon as possible if 
tolerated. The patients receiving study drug at dose level 2 in PARAGON-HF can start with 
either the same dose level or the next lower dose level based on the investigator's clinical 
judgement. The patients who are not on study medication at screening visit and eligible should 
start at dose level 1.
4.3
Rationale for choice of control drugs (comparator/placebo) or 
combination drugs
Not applicable.
4.4
Purpose and timing of interim analyses/design adaptations
Not applicable.
4.5
Risks and benefits
Patients will be instructed not to take any RAS blockade medications (ACEI or ARB) while 
they take study drug to avoid excess RAS blockade. All patients will be allowed to continue 
receiving the rest of their background CV medications. The risk to patients in this study will be 
minimized by compliance with the eligibility criteria and close clinical monitoring. In women 
of child-bearing potential, a possible risk of developmental toxicity cannot be excluded. Women 
of child-bearing potential should therefore use a highly effective method of contraception 
during dosing and for 7 days off study medication. If there is any question that the patient will 
not reliably comply, they should not be entered in the study. All patients in this study will be 
≥50 years of age because all patients participated in PARAGON-HF were ≥50 years of age, 
and therefore the risk of pregnancy during the trial is minimal.
Since this study is following PARAGON-HF, participating patients to this study will benefit 
from continuous effect of LCZ696 thorough the continuous access from PARAGON-HF to 
open-label LCZ696 that avoids the treatment interruption. If the primary endpoint of 
PARAGON-HF is not met, the study will be terminated as soon as possible.

Population
The study population will consist of Japanese patients with HFpEF who completed 
PARAGON-HF. It is anticipated that approximately 70 Japanese patients will complete the 
PARAGON-HF, of which approximately 80% are anticipated to enrol into this study.
5.1
Inclusion criteria
Subjects eligible for inclusion in this study must meet all of the following criteria:
1. Signed informed consent must be obtained before any assessment is performed.
2. Patients who have completed PARAGON-HF and are able to be safely enrolled into this 
study as judged by the investigator.
5.2
Exclusion criteria
Subjects meeting any of the following criteria are not eligible for inclusion in this study.
1. Patients who discontinued study drug treatment during PARAGON-HF due to an event or 
intercurrent illness. Eligibility can be re-considered if the event has resolved and no longer 
represents a risk to the patient and the patient can safely tolerate the administration of 
LCZ696 per the investigator’s assessment.
2. Any medical condition that in the opinion of the investigator is likely to prevent the 
patient from safely tolerating LCZ696 or complying with the requirements of the study.
3. Patients who have experience of angioedema event(s) which occurred and reported by the 
investigator during PARAGON-HF.
4. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female 
after conception and until the termination of gestation, confirmed by a positive human 
chorionic gonadotropin (hCG) laboratory test.
5. Women of childbearing potential, defined as all women physiologically capable of 
becoming pregnant, unless they are using highly effective methods of contraception 
while taking study treatment and for 7 days of after stopping medication. Highly 
effective contraception methods include:

Total abstinence (when this is in line with the preferred and usual lifestyle of the 
subject. Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation 
methods) and withdrawal are not acceptable methods of contraception)

Female sterilization (have had surgical bilateral oophorectomy with or without 
hysterectomy), total hysterectomy, or tubal ligation at least six weeks before taking 
study treatment. In case of oophorectomy alone, only when the reproductive status of 
the woman has been confirmed by follow up hormone level assessment

Male sterilization (at least 6 months prior to Visit 1). For female subjects on the study, 
the vasectomized male partner should be the sole partner for that subject

Combination of any two of the following (a+b, a+c, or b+c), acording to country 
approvals and availability:
a. Barrier methods of contraception: Condom or Occlusive cap (diaphragm or 
cervical/vault caps) with spermicidal foam/gel/film/cream/ vaginal 
suppository

Page 17
Clinical Trial Protocol (Version No. 00)
Protocol No. CLCZ696D1301E1
b. Use of oral, (estrogen and progesterone), injected or implanted hormonal 
methods of contraception or other forms of hormonal contraception that have 
comparable efficacy (failure rate <1%), for example hormone vaginal ring or 
transdermal hormone contraception
c. Placement of an intrauterine device (IUD) or intrauterine system (IUS).

In case of use of oral contraception women should have been stable on the same pill 
for a minimum of 3 months before taking study treatment.

Women are considered post-menopausal and not of child bearing potential if they 
have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical 
profile (e.g. age appropriate history of vasomotor symptoms) or have had surgical 
bilateral oophorectomy (with or without hysterectomy), total hysterectomy or tubal 
ligation at least six weeks ago. In the case of oophorectomy alone, only when the 
reproductive status of the woman has been confirmed by follow up hormone level 
assessment is she considered not of childbearing potential.
If local regulations deviate from the contraception methods listed above to prevent 
pregnancy, local regulations apply and will be described in the Informed Consent Form 
(ICF).

6.1.4
Treatment duration
This study will continue until marketed product is available in Japan, or approximately for 2 
years from the date of the first patient enrolled, whichever comes first. Subjects may be 
discontinued from treatment earlier due to unacceptable toxicity, disease progression and/or 
treatment is discontinued at the discretion of the investigator or the subject.
6.2
Other treatment(s)
6.2.1
Concomitant therapy
The investigator should instruct the patient to notify the study site about any new medications 
he/she takes after the patient was enrolled into the study. All medications, procedures and 
significant non-drug therapies (including physical therapy and blood transfusions) administered 
after the subject was enrolled into the study must be recorded on the appropriate Case Report 
Forms (CRF).
CV medications
The patient should be on an optimal medical regimen of diuretics and background medications 
to effectively treat comorbidities, such as HTN, DM, AF and coronary artery disease. 
Investigators should take into consideration the patient’s risk factors, such as age and 
comorbidities, and make every effort to control a patient’s BP in accordance with international 
and local treatment guidelines, as well as other evidence-based medicine. The concomitant use 
of ACEIs, ARBs or renin inhibitor is strictly prohibited while the patient is receiving study drug 
(Section 6.2.2).
Medications known to raise potassium levels
Potassium-sparing diuretics, potassium supplements, MRAs and any other medications known 
to raise potassium levels should be used with caution while the patient is receiving the study 
drug due to the increased possibility of occurrence of hyperkalemia. The investigator is 
encouraged to assess patients’ potassium levels regularly, especially in those who are receiving 
these medications.
Phosphodiesterase-5 (PDE-5) inhibitors
PDE-5 inhibitors should be used with caution while the patient is receiving study medication 
due to the increased possibility of the occurrence of hypotension.
Neseritide and intravenous (IV) nitrates
The concomitant administration of LCZ696 with neseritide and IV nitrates has not been studied. 
In the event a study patient requires the concomitant administration of neseritide and/or IV 
nitrates with the study medications, the investigator should consider starting them at a lower 
dose or a slower infusion rate while monitoring the patient’s BP carefully.

HMG-CoA reductase inhibitors
Caution is recommended when co-administering LCZ696 with atorvastatin or other statins (e.g. 
simvastatin, pravastatin) that are substrates of organic anion-transporting polypeptide (OATP) 
1B1 and OATP1B3 because of the potential to raise plasma statin levels.
6.2.2
Prohibited medication
Use of the treatments displayed in the below table are not allowed after the start of study 
treatment due to safety reasons, unless the actions specified are taken.
Table 6-1
Prohibited medication
Medication
Action taken
Any ACEI
Discontinue study drug. The ACEI must be stopped for ≥36 
hours prior to re-initiation of study drug
Any ARB
Discontinue study drug. The ARB must be stopped prior to re-
initiation of study drug
Any renin inhibitor
Discontinue study drug. The renin inhibitor must be stopped 
prior to re-initiation of study drug
The concomitant use of ACEIs, ARBs or renin inhibitor is strictly prohibited while the patient 
is receiving study drug. If the addition of an ACEI, ARB or renin inhibitor is necessary, then 
study drug must be temporarily discontinued. If the patient is to be started on ACEI, the study 
drug must be stopped ≥ 36 hours prior to initiating ACEI. If study drug is to start the ACEI must 
be stopped ≥ 36 hours prior to re-initiating study drug. ARBs or a renin inhibitor should be 
stopped prior to resuming study drug.
6.2.3
Rescue medication
Guidance on handling hyperkalemia, hypotension, and renal dysfunction are provided to 
investigators in Section 16.3 Appendix3, Appendix 4 and Appendix 5, respectively. Patients 
may receive ACEIs, ARBs or a renin inhibitor during the study ONLY if the study drug has 
been temporarily discontinued.
Use of rescue medication must be recorded on an appropriate CRF.
6.3
Subject numbering, treatment assignment, randomization
6.3.1
Subject numbering
Each subject is identified in the study by a Subject Number (Subject No.) that is assigned when 
the subject is first enrolled for screening and is retained as the primary identifier for the subject 
throughout his/her entire participation in the trial. The Subject No. consists of the Center 
Number (Center No.; as assigned by Novartis to the investigative site) with a sequential subject 
number suffixed to it, so that each subject is numbered uniquely across the entire database. 
Upon signing the informed consent form, the patient is assigned to the next sequential Subject 
No. available.

Treatment assignment, randomization
No randomization will be performed in this study. During this study, all patients will be treated 
with LCZ696 at maximally tolerated dosed with a target dose of 200 mg b.i.d.
6.4
Treatment blinding
Treatment will be open to subjects, investigator staff, persons performing the assessments, and 
the sponsor.
6.5
Dose escalation and dose modification
Investigational or other study treatment dose adjustments and/or interruptions are permitted.
6.5.1
Dose escalation guidelines
6.5.1.1
Starting dose
LCZ696 will be dispensed and the patient will be required to take one tablet of the assigned 
study medication twice a day for the duration of the study. The dose level dispensed at Visit 
101 will be either 50 mg b.i.d. (dose level 1) or 100 mg b.i.d. (dose level 2) largely depending 
on the last dose level taken by the patient at the time of completing PARAGON-HF and patient 
condition. The dose level should be gradually up-titrated at subsequent visit with the goal of 
reaching the target dose of 200 mg b.i.d. (dose level 3) as soon as tolerated by the patient (see 
Figure 3-1 and Table 3-1).
6.5.2
Dose modifications
For subjects who do not tolerate the protocol-specified dosing schedule, dose level adjustments 
and interruptions of study treatment are permitted in order to allow subjects to continue the 
study treatment. The following guidelines should be followed:
Every attempt should be made to maintain patients at the target study drug dose level throughout 
the study. If the patient does not tolerate the target study drug dose level, the investigator can 
adjust or stop concomitant background medications for co-morbid conditions to rectify the 
situation, before considering down-titration to the next lower study drug dose level. For 
hypotension or dizziness, consideration should be given to reduce the dose or to stop 
concomitant antihypertensive agents and non-antihypertensive agents that lower BP, or the dose 
of diuretic can be reduced.
These dose changes must be recorded on the appropriate CRF.
Adjustment of study drug dose level
If despite adjustment of concomitant medications per the guidance provided the situation is not 
rectified, the investigator may consider down titrating the study drug dose level according to 
the following instructions:
During the study, down titration of the study drug at any time based on the judgment of the 
investigator will be allowed taking into account the safety and tolerability criteria defined in 
Section 16.3 Appendix3, Appendix 4, and Appendix 5. If down titration is necessary, the patient 

Novartis
Confidential
Page 21
Clinical Trial Protocol (Version No. 00)
Protocol No. CLCZ696D1301E1
should be down titrated to the next lower study drug dose level (Table 6-2). The patient may 
continue receiving the lower dose level for a recommended period of 1 to 4 weeks before being 
re-challenged at the next higher dose level. For example, a patient who encounters tolerability 
problems at the target study drug dose level (dose level 3), should receive the study drug at dose 
level 2 for 1 to 4 weeks at the discretion of the investigator. Then, he/she should be re-
challenged with up-titration back to dose level 3.
If the tolerability issues are not alleviated despite down titration by one dose level, the
investigator may down titrate further to the next lower study drug dose level for 1 to 4 weeks, 
up to temporary discontinuation of the study drug. Again, once stable, the patient should be re-
challenged with up titration to the next higher dose level every 1 to 4 weeks in an attempt to 
bring back the patient gradually to the target study drug dose level (dose level 3). The 
investigator may choose the next dose level for down- or up-titration according to his or her 
judgment (Table 6-2).
In some instances, the investigator’s judgment, dose level 1 or 2 could be maintained if he/she 
considers that the patient’s condition would not allow any further up titration to the target dose 
level of study drug (dose level 3). In this case, it would be acceptable to maintain the patient at 
dose level 1 or level 2, whichever is the higher and tolerated dose level by the patient.
Study drug restart after temporary treatment interruption
Study drug should be reintroduced in those patients who temporarily discontinue it as soon as 
medically justified in the opinion of the investigator.
Once the investigator considers the patient’s condition appropriate for receiving the study drug, 
the investigator should re-start the patient on the study drug at the most appropriate and 
allowable dose level (Table 6-2) per his/her medical judgment. If tolerated, the patient should 
be up-titrated a dose level every 1 to 4 weeks to the target dose level 3, as per the investigator’s 
judgment. Should the patient not tolerate the re-start study drug dose level, he/she may be down 
titrated again (if appropriate) or temporarily discontinue the study medication again and a new 
attempt to up titrate or reintroduce the study drug could be considered by the investigator as 
soon as medically justified in his/her judgment.
The use of an ACEI, ARB or a renin inhibitor is strongly discouraged while patient is taking 
study drug. However, if for any reason a patient off study drug has started treatment with an 
ACEI, it must be discontinued ≥36 hours prior to restarting study drug. For patients off study 
drug treated with an ARB or a renin inhibitor it must be discontinued prior to re-initiation of 
study drug (Table 6-1).
These changes must be recorded on an appropriate CRF.
In case of pregnancy discovered during the study, the patient will be withdrawn from the study 
immediately. See Section 10.1.4 for further details on pregnancies and reporting guidelines.

Additional treatment guidance
6.6.1
Treatment compliance
All dosages prescribed and dispensed to the patient and all dose changes during the study must 
be recorded on the appropriate CRF.
The investigator should promote compliance by instructing the patient to take the drug exactly 
as prescribed and by stating that compliance is necessary for the patient’s safety and the validity 
of the study. The patient should be instructed to contact the investigator if he/she is unable for 
any reason to take the study drug as prescribed.
Compliance will be assessed by the investigator and/or study personnel at each visit using pill 
counts and information provided by the patient and/or the caregiver. This information should
be captured in the source document at each visit. The investigator and/or study personnel should 
counsel the patient if compliance is below 80% at any time during the study. Study drug 
accountability will be determined by the site monitor while performing routine site visits and at 
the completion of the study.
The duration of treatment exposure will be calculated based upon the start and stop dates 
recorded in the CRF.
6.6.2
Emergency breaking of assigned treatment code
Not applicable.
6.7
Preparation and dispensation
Each study site will be supplied with study drug in packaging as described for clinical trial use

his/her understanding. If the subject is capable of doing so, he/she must indicate agreement by 
personally signing and dating the written informed consent document.
Informed consent must be obtained before conducting any study-specific procedures (e.g. all of 
the procedures described in the protocol). The process of obtaining informed consent must be 
documented in the subject source documents.
Novartis will provide to investigators in a separate document a proposed informed consent form 
that complies with the International Conference on Harmonization of Technical Requirements 
for Registration of Pharmaceuticals for Human Use (ICH) Good Clinical Practice (GCP) 
guidelines and regulatory requirements and is considered appropriate for this study. Any 
changes to the proposed consent form suggested by the investigator must be agreed by 
Novartis before submission to the IRB/IEC.
Information about common side effects already known about the investigational drug can be 
found in the Investigator's Brochure (IB). This information will be included in the subject 
informed consent and should be discussed with the subject during the study as needed. Any new 
information regarding the safety profile of the investigational drug that is identified between IB 
updates will be communicated as appropriate, for example, via an investigator notification (IN) 
or an aggregate safety finding. New information might require an update to the informed 
consent and then must be discussed with the subject.
Women of child bearing potential must be informed that taking the study treatment may involve 
unknown risks to the fetus if pregnancy were to occur during the study and agree that in order 
to participate in the study they must adhere to the contraception requirements.
A copy of the approved version of all consent forms must be provided to Novartis after IRB/IEC 
approval.

Visit schedule and assessments
Table 8-1 lists all of the assessments for this study. The table indicates which data are entered 
into CRF from the source data (X), remain in the source documents only (S). At the study end, 
all patients will return to the study sites as soon as possible to undergo the End of Study (EOS) 
visit assessments.
Assessment schedule lists all of the assessments when they are performed. All data obtained 
from these assessments must be supported in the subject’s source documentation.
Subjects should be seen for all visits/assessments as outlined in the assessment schedule or as 
close to the designated day/time as possible. Missed or rescheduled visits should not lead to 
automatic discontinuation. Subjects who prematurely discontinue the study for any reason 
should be scheduled for a visit as soon as possible, at which time all of the assessments listed 

Novartis

for the final visit will be performed. Permanent discontinuation of study drug constitutes 
withdrawal from the study. At this final visit, all dispensed investigational product should be 
reconciled, and the adverse event and concomitant medications recorded on the CRF.
At a minimum, patients will be contacted for safety evaluations during the 30 days following 
the last study visit or following the last administration of study drug (whichever is later), 
including a final contact at the 30-day point. This follow up may be a phone call. Documentation 
of attempts to contact the patient should be recorded in the source documentation.

8.1
Screening
Re-screening will not be allowed in this study.
8.1.1
Information to be collected on screening failures
Subjects who sign an informed consent form and subsequently found to be ineligible will be 
considered a screen failure. The reason for screen failure should be entered on the applicable 
Case Report Form. The demographics, inclusion/exclusion, and informed consent pages must 
also be completed for screening failure subjects. No other data will be entered into the clinical 
database for subjects who are screen failures, unless the subject experienced a SAE after signing 
informed consent. A SAE occurred after signing informed consent until confirming screening 
failure should be reported.
For all patients who have signed informed consent and receive study treatment all AEs 
occurring after informed consent is signed will be recorded on the Adverse Event CRF.
8.2
Subject demographics/other baseline characteristics
Patient demographic and baseline characteristic data to be collected on all patients include: age, 
sex, race, ethnicity. 
8.3
Efficacy
8.3.1
Appropriateness of efficacy assessments
Efficacy is not measured in this study.
8.4
Safety
Safety assessments are specified below with the assessment schedule detailing when each 
assessment is to be performed. If the abnormality for each assessment (e.g. laboratory test, vital 
sign) induces clinical signs or symptoms, or requires therapeutic intervention, then the diagnosis 
or medical condition must be entered on the AE CRF. For details on AE collection and reporting, 
refer to AE section.
Novartis may request additional information on specific AEs or laboratory events of interest 
and may make requests to perform additional diagnostic tests to further assess the safety profile 
of the study drugs. Such information may include diagnostic procedure reports, discharge 
summaries, autopsy reports, and other relevant information that may help in assessing the 
reported AE. All additional information will be de-identified prior to collection by Novartis or 
its agents.
8.4.1
Laboratory evaluations
Laboratory assessments will be analyzed locally during the study. Values outside the normal
ranges and notable values should be flagged on the report. It is the responsibility of the 
investigator to review all laboratory results and make an assessment of whether an abnormal or 
notable value is clinically significant, whether additional evaluations should be performed as 

Novartis
Confidential
Page 28
Clinical Trial Protocol (Version No. 00)
Protocol No. CLCZ696D1301E1
judged appropriate, and whether the patient may continue in the trial. Sample collection should 
be conducted according to the standards and requirements of the local laboratory.
Serum potassium and creatinine will be evaluated locally at all visits in Table 8-1. Additional 
laboratory evaluation should be performed by Investigator's judgement at any visits.
8.4.2
Pregnancy and assessments of fertility
All pre-menopausal women who are not surgically sterile will have serum pregnancy test locally 
at visit 1. A urine dip-stick pregnancy test should be performed locally at other visits defined in 
Table 8-1. If positive, the patient must discontinue study drug until after the pregnancy and 
lactation period.
8.4.3
Appropriateness of safety measurements
The safety assessments selected are standard for this indication/subject population.
8.4.4
Physical assessments
A physical exam will include the examination of general appearance and vital signs (BP 
[systolic blood pressure (SBP) and diastolic blood pressure (DBP)] and pulse). If indicated 
based on medical history and/or symptoms, other exams will be performed by Investigator's 
judgement. A physical exam will be conducted at all visits starting from Visit 1(see Table 8-1).
Information from all physical examinations must be included in the source documentation at 
the study site.Significant findings made after signing the informed consent which meet the 
definition of an AE must be recorded on the AE section of the CRF.
8.4.5
Vital sign
Vital signs include BP and pulse measurements. BP will be measured in the sitting position 
after 5 minutes of rest using an automated validated device (e.g. OMRON) or a standard 
sphygmomanometer with an appropriately sized cuff on the non-dominant arm. Guidelines for 
the management of BP are provided in Appendix 4.
8.4.6
Angioedema
Angioedema is a type of abrupt swelling that occurs under the skin and/or mucous membranes 
and is often localized to the head, neck, throat, and/or tongue, but may occur elsewhere, 
including the genitalia and intestines. Severe cases may be associated with airway compromise.
It is important that the investigator pays special attention to any swelling or edema that may 
resemble angioedema or angioedema-like events that may be reported by patients. If such an 
event occurs, the investigator will complete an Adjudication Questionnaire for an Angioedema-
like Event form (provided by Novartis) to summarize the event, its treatment, and its ultimate 
outcome. This report along with the requisite medical documentation must be submitted to 
Novartis as soon as possible. Follow-up reports must be communicated to Novartis as soon as 
new information regarding the event becomes available. All hospital records related to the event 
must be communicated to Novartis.
The investigator may be also be contacted by Novartis regarding AEs that may resemble an 
angioedema-like event. A list of terms that are considered “angioedema-like” (e.g., periorbital 

Novartis
Confidential
Page 29
Clinical Trial Protocol (Version No. 00)
Protocol No. CLCZ696D1301E1
swelling) will be provided to sites in a manual. The investigator or his/her delegated staff must 
complete the required forms and provide the required medical records for all such events, 
regardless of whether the investigator views the event in question as angioedema or not.
All angioedema reports will be forwarded to an Angioedema Adjudication Committee by 
Novartis for assessment.
Information regarding this committee is outlined in Section 10.2.2. Details on the procedures 
for reporting angioedema events will be provided to investigators in a manual.
8.5
Additional assessments
No additional tests will be performed on subjects entered into this study.
9
Study discontinuation and completion
9.1
Discontinuation
9.1.1
Discontinuation of study treatment
Patients may voluntarily discontinue study treatment for any reason at any time.
Permanent discontinuation of study drug for a subject occurs when study treatment is stopped 
earlier than the protocol planned duration, and can be initiated by either the subject or the 
investigator.
The investigator must discontinue investigational treatment for a given subject if, he/she 
believes that continuation would negatively impact the subject's well-being.
If discontinuation of study treatment occurs, the investigator should make a reasonable effort 
to understand the primary reason for the subject’s premature discontinuation of study treatment 
and record this information. Always consider reasons which are related to safety and efficacy 
first.
Subjects who discontinue investigational treatment permanently or who decide they do not wish 
to participate in the study further should NOT be considered withdrawn from the study 
UNLESS they withdraw their consent (see Section 9.1.2, withdrawal of informed consent). 
They will be expected to perform the EOS Visit.
If they fail to return for the EOS visit assessments for unknown reasons, every effort (e.g. 
telephone, e-mail, letter) should be made to contact the subject/pre-designated contact as 
specified in the lost to follow-up section. This contact should preferably be done according to 
the study visit schedule.
Subjects who discontinue treatment early will be expected to perform the final visit(EOS). All 
dispensed investigational product should be reconciled and the adverse event and concomitant 
medications reconciled on the appropriate CRF.
In case that a patient is to be switched from an LCZ696 to an ACEI, a 36-hour LCZ696-free 
washout should be implemented prior to the initiation of ACEI intake to minimize the risk of 
occurrence of angioedema. Similarly, a ACEI-free 36-hour washout should be implemented 
when switching a patient from an ACEI to an LCZ696. Patient management and safety 

Novartis
Confidential
Page 30
Clinical Trial Protocol (Version No. 00)
Protocol No. CLCZ696D1301E1
monitoring guidelines, including implementation of the appropriate washout periods, should 
refer to LCZ696D2301 (PARAGON-HF) or approved label whichever is most appropriate.
9.1.2
Withdrawal of informed consent
Subjects may voluntarily withdraw consent to participate in the study for any reason at any time. 
Withdrawal of consent occurs only when a subject:

Does not want to participate in the study anymore, and

Does not allow further collection of personal data
In this situation, the investigator should make a reasonable effort (e.g. telephone, e-mail, letter) 
to understand the primary reason for the subject’s decision to withdraw his/her consent and 
record this information.
Study treatment must be discontinued and no further assessments conducted, and the data that 
would have been collected at subsequent visits will be considered missing.
Further attempts to contact the subject are not allowed unless safety findings require 
communicating or follow-up.
All efforts should be made to complete the assessments prior to study withdrawal. A final 
evaluation at the time of the subject’s study withdrawal should be made as detailed in the 
Assessment.
Novartis will continue to keep and use collected study information (including any data resulting 
from the analysis of a subject’s samples until the time of withdrawal) according to applicable 
law.
9.1.3
Lost to follow-up
For subjects whose status is unclear because they fail to appear for study visits without stating 
an intention to discontinue or withdraw, the investigator must show "due diligence" by 
documenting in the source documents steps taken to contact the subject, e.g. dates of telephone 
calls, registered letters, etc. A subject should not be considered as lost to follow-up until the end 
of the study.
9.1.4
Early study termination by the sponsor
The study can be terminated by Novartis at any time for any reason. This may include reasons 
related to the benefit/ risk assessment of participating in the study, practical reasons (including 
slow enrollment), or for regulatory or medical reasons.
If the primary endpoint of PARAGON-HF is not met, this study will be terminated and the 
patient must be safely switched from open-label LCZ696 to alternative treatment based on the 
investigator’s clinical judgement as soon as possible.
In taking the decision to terminate the study, Novartis will always consider the subject's welfare 
and safety. Should early termination be necessary, subjects must be seen as soon as possible and 
treated as a prematurely withdrawn subject. The investigator may be informed of additional 
procedures to be followed in order to ensure that adequate consideration is given to the 
protection of the subject’s interests. The investigator or sponsor depending on the local 
regulation will be responsible for informing IRBs/IECs of the early termination of the trial.

9.2
Study completion and post-study treatment
Study completion is defined as when the last subject finishes their Study Completion (EOS) 
visit and any repeat assessments associated with this visit have been documented and followed-
up appropriately by the Investigator or, in the event of an early study termination decision, the 
date of that decision.
All treated subjects should have a safety follow-up call conducted 30 days after last 
administration of study treatment. The information collected is kept as source documentation. 
All SAEs reported during this time period must be reported as described in Section 10.1.3. 
Documentation of attempts to contact the subject should be recorded in the source 
documentation.

Safety monitoring and reporting
10.1
Definition of adverse events and reporting requirements
10.1.1
Adverse events
An adverse event (AE) is any untoward medical occurrence (e.g. any unfavorable and 
unintended sign [including abnormal laboratory findings], symptom or disease) in a subject or 
clinical investigation subject after providing written informed consent for participation in the 
study. Therefore, an AE may or may not be temporally or causally associated with the use of a 
medicinal (investigational) product.
The investigator has the responsibility for managing the safety of individual subject and 
identifying adverse events.
Novartis qualified medical personnel will be readily available to advise on trial related medical 
questions or problems.
The occurrence of adverse events must be sought by non-directive questioning of the subject at 
each visit during the study. Adverse events also may be detected when they are volunteered by 
the subject during or between visits or through physical examination findings, laboratory test 
findings, or other assessments.
Adverse events must be recorded under the signs, symptoms, or diagnosis associated with them, 
accompanied by the following information (as far as possible) (if the event is serious refer to 
Section 10.1.2):
1. The Common Toxicity Criteria (CTC) AE grade (version 5 or higher).
2. its relationship to the study treatment. If the event is due to lack of efficacy or progression 
of underlying illness (i.e. progression of the study indication) the assessment of causality 
will usually be ‘Not suspected.’ The rationale for this guidance is that the symptoms of a 
lack of efficacy or progression of underlying illness are not caused by the trial drug, they 
happen in spite of its administration and/or both lack of efficacy and progression of 
underlying disease can only be evaluated meaningfully by an analysis of cohorts, not on a 
single subject
3. its duration (start and end dates) or if the event is ongoing, an outcome of not 
recovered/not resolved must be reported

Novartis
Confidential
Page 32
Clinical Trial Protocol (Version No. 00)
Protocol No. CLCZ696D1301E1
4. whether it constitutes a SAE (see Section 10.1.2 for definition of SAE) and which 
seriousness criteria have been met
5. action taken regarding with study treatment
All adverse events must be treated appropriately. Treatment may include one or more of the 
following:

Dose not changed

Dose Reduced/increased

Drug interrupted/withdrawn

its outcome (i.e. recovery status or whether it was fatal)
Conditions that were already present at the time of informed consent should be recorded in 
medical history of the subject.
Adverse events (including lab abnormalities that constitute AEs) should be described using a 
diagnosis whenever possible, rather than individual underlying signs and symptoms.
Adverse event monitoring should be continued for at least 30 days following the last dose of 
study treatment or end of study visit, whichever is longer.
Once an adverse event is detected, it must be followed until its resolution or until it is judged to 
be permanent (e.g. continuing at the end of the study), and assessment must be made at each 
visit (or more frequently, if necessary) of any changes in severity, the suspected relationship to 
the interventions required to treat it, and the outcome.
Information about adverse drug reactions for the investigational drug can be found in the 
Investigator's Brochure (IB).
Abnormal laboratory values or test results constitute adverse events only if they fulfill at least 
one of the following criteria:

they induce clinical signs or symptoms

they are considered clinically significant

they require therapy
Clinically significant abnormal laboratory values or test results must be identified through a 
review of values outside of normal ranges/clinically notable ranges, significant changes from 
baseline or the previous visit, or values which are considered to be non-typical in subjects with 
the underlying disease. Alert ranges for laboratory and other test abnormalities are included in 
Section 16.1 Appendix1.
For lab values provided without related clinical information, the CTCAE scale must be used to 
determine the seriousness. Any value of Grade 4 and above on this CTCAE scale must be 
considered serious.
10.1.2
Serious adverse events
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:

fatal

Novartis
Confidential
Page 33
Clinical Trial Protocol (Version No. 00)
Protocol No. CLCZ696D1301E1

life-threatening
Life-threatening in the context of a SAE refers to a reaction in which the subject 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 it were more severe (please refer to the ICH-E2D Guidelines).

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: 

routine treatment or monitoring of the studied indication, not associated with any 
deterioration in condition

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

social reasons and respite care in the absence of any deterioration in the subject’s 
general condition

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

is medically significant, e.g. defined as an event that jeopardizes the subject or may 
require medical or surgical intervention to prevent one of the outcomes listed above
Medical and scientific judgment should be exercised in deciding whether other situations should 
be considered serious reactions, such as important medical events that might not be immediately 
life threatening or result in death or hospitalization but might jeopardize the subject or might 
require intervention to prevent one of the other outcomes listed above. Such events should be 
considered as “medically significant.” Examples of such events are intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias, or convulsions that 
do not result in hospitalization or development of dependency or abuse (please refer to the ICH-
E2D Guidelines).
All malignant neoplasms will be assessed as serious under “medically significant” if other 
seriousness criteria are not met and the malignant neoplasm is not a disease progression of the 
study indication.
Any suspected transmission via a medicinal product of an infectious agent is also considered a 
serious adverse reaction.
All reports of intentional misuse and abuse of the product are also considered serious adverse 
event irrespective if a clinical event has occurred. 
10.1.3
SAE reporting
To ensure subject safety, every SAE, regardless of causality, occurring after the subject has 
provided informed consent and until 30 days after the last study visit must be reported to 
Novartis safety within 24 hours of learning of its occurrence. Detailed instructions regarding 
the submission process and requirements are to be found in the investigator folder provided to 
each site. Any SAEs experienced after the 30 day period after the last study visit should only 
be reported to Novartis Safety if the investigator suspects a causal relationship to study 
treatment.

Novartis
Confidential
Page 34
Clinical Trial Protocol (Version No. 00)
Protocol No. CLCZ696D1301E1
Recurrent episodes, complications, or progression of the initial SAE must be reported as follow-
up to the original episode, regardless of when the event occurs. This report must be submitted 
within 24 hours of the investigator receiving the follow-up information. An SAE that is 
considered completely unrelated to a previously reported one should be reported separately as 
a new event.
Information about all SAEs is collected and recorded on the Serious Adverse Event Report 
Form; all applicable sections of the form must be completed in order to provide a clinically 
thorough report. The Investigator must assess the relationship of each SAE to each specific 
component of the study treatment (if the study treatment consists of several components) 
complete the SAE Report Form in English and submit the completed form within 24 hours to 
Novartis. Detailed instructions regarding the submission process and requirements for signature 
are to be found in the investigator folder provided to each site.
Consider the following 2 categories (as applicable) to determine SAE reporting timeframes:
1. Screen Failures (e.g. a subject who is screened but is not treated): SAEs occurring after 
the subject has provided informed consent until the time the subject is deemed a Screen 
Failure must be reported to Novartis.
2. Treated Subjects: SAEs collected between time subject signs ICF until 30 days after the 
subject has discontinued or stopped study treatment.
All follow-up information for the SAE including information on complications, progression of 
the initial SAE and recurrent episodes must be reported as follow-up to the original episode 
within 24 hours of the investigator receiving the follow-up information. An SAE occurring at a 
different time interval or otherwise considered completely unrelated to a previously reported 
one must be reported separately as a new event.
If the SAE is not previously documented in the Investigator’s Brochure or Package Insert (new 
occurrence) and is thought to be related to the study treatment, a Chief Medical Office and 
Patient Safety (CMO&PS) Department associate may urgently require further information from 
the investigator for health authority reporting. Novartis may need to issue an Investigator 
Notification (IN) to inform all investigators involved in any study with the same study treatment 
that this SAE has been reported.
Suspected Unexpected Serious Adverse Reactions (SUSARs) will be collected and reported to 
the competent authorities and relevant ethics committees (EC) in accordance with European 
Union (EU) Guidance 2011/C 172/01 or as per national regulatory requirements in participating 
countries.
Any SAEs experienced after the 30 day period after the last study visit should only be reported 
to Novartis Safety if the investigator suspects a causal relationship to study treatment.
Detailed instructions regarding the submission process and requirements are to be found in the 
investigator folder provided to each site.
10.1.4
Pregnancy reporting
To ensure subject safety, each pregnancy occurring after signing the informed consent must be 
reported to Novartis within 24 hours of learning of its occurrence. The pregnancy should be 
followed up to determine outcome, including spontaneous or voluntary termination, details of 

Novartis
Confidential
Page 35
Clinical Trial Protocol (Version No. 00)
Protocol No. CLCZ696D1301E1
the birth, and the presence or absence of any birth defects, congenital abnormalities, or maternal 
and/or newborn complications.
Pregnancy should be recorded and reported by the investigator to the Novartis/CMO&PS. 
Pregnancy follow-up should be recorded on the same form and should include an assessment 
of the possible relationship to the study treatment any pregnancy outcome. The follow-up 
should be for up to 12 months following the birth of the baby. Any SAE experienced during 
pregnancy must be reported.
10.1.5
Reporting of study treatment errors including misuse/abuse
Medication errors are unintentional errors in the prescribing, dispensing, administration or 
monitoring of a medicine while under the control of a healthcare professional, subject or 
consumer (European Medicines Agency (EMA) definition).
Misuse refers to situations where the medicinal product is intentionally and inappropriately used 
not in accordance with the protocol.
Abuse corresponds to the persistent or sporadic, intentional excessive use of a medicinal product, 
which is accompanied by harmful physical or psychological effects.
Study treatment errors and uses outside of what is foreseen in the protocol will be recorded on 
the appropriate CRF irrespective of whether or not associated with an AE/SAE and reported to 
Safety only if associated with an SAE. Misuse or abuse will be collected and reported in the 
safety database irrespective of it being associated with an AE/SAE within 24 hours of 
Investigator’s awareness.

Additional Safety Monitoring
10.2.1
Liver safety monitoring
To ensure subject safety and enhance reliability in determining the hepatotoxic potential of an 
investigational drug, a standardized process for identification, monitoring and evaluation of 
liver events has to be followed.
The following two categories of abnormalities / adverse events have to be considered during 
the course of the study (irrespective of whether classified/reported as AE/SAE):

Liver laboratory triggers, which will require repeated assessments of the abnormal 
laboratory parameter

Novartis
Confidential
Page 36
Clinical Trial Protocol (Version No. 00)
Protocol No. CLCZ696D1301E1

Liver events, which will require close observation, follow-up monitoring and contributing 
factors are recorded on the appropriate CRFs
Please refer to Table 16-1 in Appendix 2 for complete definitions of liver laboratory triggers 
and liver events.
Every liver event defined in Table 16-1 should be followed up by the investigator or designated 
personnel at the trial site, as summarized below. Additional details on actions required in case 
of liver events are outlined in Table 16-2 . Repeat liver chemistry tests (i.e. alanine 
aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBL), prothrombin 
time/international normalized ratio (PT/INR), alkaline phosphatase (ALP), gamma glutamyl 
transferase (GGT)) to confirm elevation.

These liver chemistry repeats should be performed using the local laboratory used by the 
site. Repeated laboratory test results must be reported as appropriate.

If the initial elevation is confirmed, close observation of the subject will be initiated, 
including consideration of treatment interruption if deemed appropriate.

Discontinuation of the investigational drug (refer to the Discontinuation of study treatment 
section), if appropriate

Hospitalization of the subject if appropriate

Causality assessment of the liver event

Thorough follow-up of the liver event should include 

These investigations can include based on investigator’s discretion: serology tests, 
imaging and pathology assessments, hepatologist’s consultancy; obtaining more 
detailed history of symptoms and prior or concurrent diseases, history of concomitant 
drug use, exclusion of underlying liver disease
All follow-up information and procedures performed must be recorded as appropriate in the 
CRF.
10.2.2
Angioedema Adjudication Committee
If an angioedema or angioedema-like event occurs, the investigator will complete an 
Adjudication Questionnaire in eCRF. Details on the process of reporting angioedema and 
angioedema like events are outlined in a manual provided to investigators.
Submission of an angioedema-like event report is not a substitution for the submission of an 
SAE report if the event meets the definition of an SAE. If an angioedema-like event satisfies 
the definition of an SAE, the investigator must submit an SAE report in addition to the 
Adjudication Questionnaire for an Angioedema-like Event.
The membership and responsibilities of the Angioedema Adjudication Committee are defined 
in a separate document that will be provided to the sites.

Data Collection and Database management
11.1
Data collection
All data should be recorded, handled, and stored in a way that allows its accurate reporting, 
interpretation, and verification.
Designated investigator staff will enter the data required by the protocol into the Electronic 
Case Report Forms (eCRF). The eCRFs have been built using fully validated secure web-
enabled software that conforms to 21 Code of Federal Regulation (CFR) Part 11 requirements, 
Investigator site staff will not be given access to the Electric Data Capture (EDC) system until 
they have been trained. Automatic validation programs check for data discrepancies in the 
eCRFs, allow modification and/or verification of the entered data by the investigator staff.
The investigator/designee is responsible for assuring that the data (recorded on CRFs) (entered 
into eCRF) is complete, accurate, and that entry and updates are performed in a timely manner. 
The Investigator must certify that the data entered are complete and accurate
After final database lock, the investigator will receive copies of the subject data for archiving 
at the investigational site.
All data should be recorded, handled, and stored in a way that allows its accurate reporting, 
interpretation, and verification.
11.2
Database management and quality control
Novartis personnel (or designated Clinical Research Organization) will review the data entered 
by investigational staff for completeness and accuracy. Electronic data queries stating the nature 
of the problem and requesting clarification will be created for discrepancies and missing values 
and sent to the investigational site via the EDC system. Designated investigator site staff are 
required to respond promptly to queries and to make any necessary changes to the data.
Concomitant treatments, prior medications and non-drug therapy entered into the database will 
be coded using the World Health Organization (WHO) Drug Reference List, which employs 
the Anatomical Therapeutic Chemical classification system. Adverse events will be coded using 
the Medical Dictionary for Regulatory Activities (MedDRA) terminology.
Once all the necessary actions have been completed and the database has been declared to be 
complete and accurate, it will be locked Any changes to the database after that time can only 
be made after written agreement by Novartis development management.
11.3
Site monitoring
Before study initiation, at a site initiation visit or at an investigator’s meeting, a Novartis 
representative will review the protocol and data capture requirements (i.e. eCRFs) with the 
investigators and their staff. During the study, Novartis employs several methods of ensuring 
protocol and GCP compliance and the quality/integrity of the sites’ data. The field monitor will 
visit the site to check the completeness of subject records, the accuracy of data capture / data 
entry, the adherence to the protocol and to Good Clinical Practice, the progress of enrollment, 
and to ensure that study treatment is being stored, dispensed, and accounted for according to 
specifications. Key study personnel must be available to assist the field monitor during these 

Novartis

Page 38
Clinical Trial Protocol (Version No. 00)
Protocol No. CLCZ696D1301E1
visits. Continuous remote monitoring of each site’s data may be performed by a centralized 
Novartis Clinical Research Associates (CRA) organization. Additionally, a central analytics 
organization may analyze data & identify risks & trends for site operational parameters, and 
provide reports to Novartis clinical teams to assist with trial oversight.
The investigator must maintain source documents for each subject in the study, consisting of 
case and visit notes (hospital or clinic medical records) containing demographic and medical 
information, laboratory data, electrocardiograms, and the results of any other tests or 
assessments. All information on CRFs must be traceable to these source documents in the 
subject’s file. The investigator must also keep the original informed consent form signed by the 
subject (a signed copy is given to the subject).
The investigator must give the monitor access to all relevant source documents to confirm their 
consistency with the data capture and/or data entry. Novartis monitoring standards require full 
verification for the presence of informed consent, adherence to the inclusion/exclusion criteria, 
documentation of SAEs, and of data that will be used for all primary variables. Additional 
checks of the consistency of the source data with the CRFs are performed according to the 
study-specific monitoring plan. No information in source documents about the identity of the 
subjects will be disclosed.

study treatment will be listed and summarized according to the Anatomical Therapeutic 
Chemical (ATC) classification system for all subjects. 
12.4
Analysis of the primary endpoint(s)
The primary objective of this study will be to evaluate further the safety and tolerability of long-
term treatment with LCZ696 in eligible HFpEF patients who completed PARAGON-HF in 
Japan.
12.4.1
Definition of primary endpoint(s)
All safety data, including vital signs, adverse
events, are considered primary endpoints.
12.4.2
Statistical model, hypothesis, and method of analysis
The primary objective of this study is to evaluate safety and tolerability so in this study there is 
no statistical model/hypothesis defined however the assessment of safety will be based 
primarily on the frequency of AEs and SAEs.
12.4.2.1 Primary analysis
The assessment of safety will be based primarily on the frequency of AEs and SAEs. Other 
safety data will be summarized as appropriate.
The incidence of treatment-emergent AEs (new or worsened) will be summarized by primary 
system organ class, preferred term, severity, and relationship to study drug. In addition, the 
incidence of death, SAEs, and AEs leading to discontinuation will be summarized separately 
by primary system organ class and preferred term. 
The incidence of AEs related to the identified and potential risks will be summarized by SMQ 
preferred terms.
Safety analyses will be performed based on the safety set. There will be no formal statistical 
inference analysis.

Novartis maintains a robust Quality Management System (QMS) that includes all activities 
involved in quality assurance and quality control, to ensure compliance with written Standard 
Operating Procedures as well as applicable global/local GCP regulations and ICH Guidelines.
Audits of investigator sites, vendors, and Novartis systems are performed by auditors, 
independent from those involved in conducting, monitoring or performing quality control of the 
clinical trial. The clinical audit process uses a knowledge/risk based approach.
Audits are conducted to assess GCP compliance with global and local regulatory requirements, 
protocols and internal standard operational procedures (SOPs), and are performed according to 
written Novartis processes.
14
Protocol adherence
This protocol defines the study objectives, the study procedures and the data to be collected on 
study participants. Additional assessments required to ensure safety of subjects should be 
administered as deemed necessary on a case by case basis. Under no circumstances including 
incidental collection is an investigator allowed to collect additional data or conduct any 
additional procedures for any purpose involving any investigational drugs under the protocol, 
other than the purpose of the study. If despite this interdiction prohibition, data, information, 
observation would be incidentally collected, the investigator shall immediately disclose it to 
Novartis and not use it for any purpose other than the study, except for the appropriate 
monitoring on study participants.
Investigators ascertain they will apply due diligence to avoid protocol deviations. If an 
investigator feels a protocol deviation would improve the conduct of the study this must be 
considered a protocol amendment, and unless such an amendment is agreed upon by Novartis 
and approved by the IRB/IEC and Health Authorities, where required, it cannot be implemented.
14.1
Protocol amendments
Any change or addition to the protocol can only be made in a written protocol amendment that 
must be approved by Novartis, health authorities where required, and the IRB/IEC prior to 
implementation.
Only amendments that are required for subject safety may be implemented immediately 
provided the health authorities are subsequently notified by protocol amendment and the 
reviewing IRB/IEC is notified.
Notwithstanding the need for approval of formal protocol amendments, the investigator is 
expected to take any immediate action required for the safety of any subject included in this 
study, even if this action represents a deviation from the protocol. In such cases, Novartis should 
be notified of this action and the IRB/IEC at the study site should be informed according to 
local regulations.

Appendix 3: Treatment guidelines for hyperkalemia (serum 
potassium greater than or equal to 5.3 mmol/L [mEq/L]
General principles
Elevation of potassium levels above the predefined values should be repeated and confirmed 
before any action is taken.
Any patient with a serum potassium > 5.3 mmol/L (mEq/L) at any time in treatment period 
requires the Investigator to confirm the potassium concentration in a non-hemolyzed sample 
via an immediate repeat lab sample to both the clinic local lab and the study central lab.
Regular, repeated checks of potassium concentration (beyond that prescribed in the protocol) 
should continue until it is clear that the potassium concentration is stable and not rising into the 
range of concern (≥ 5.5 and < 6.0 mmol/L [mEq/L]) or potential danger (≥ 6.0 mmol/L [mEq/L]).
Patients with elevated potassium value will be managed according to the corrective actions 
outlined below. Hyperkalemia should be followed until resolution.
Corrective action for management of hyperkalemia
Serum potassium greater than 5.3 and less than or equal to 5.5 mmol/L (mEq/L)

Confirm potassium concentration in a non-hemolyzed sample

Reinforce low potassium diet and restriction of food/drinks with high potassium content 
(e.g. orange juice, melon, bananas, tomatoes, dried fruits, potatoes, low-salt substitutes, 
tomatoes, coffee, etc.)

Correct metabolic acidosis if necessary.

Review medical regimen (including dietary supplements and over-the-counter 
medications) for agents known to cause hyperkalemia. Consider reduction in dose or 
discontinuation of these agents: 

MRAs (if they are believed to be the most likely cause of hyperkalemia)

Potassium-sparing diuretics (e.g. amiloride and triamterene) including in combination 
products with thiazide or loop diuretics

Potassium supplements, e.g., potassium chloride

Salt substitutes

Non-steroidal anti-inflammatory drugs (NSAIDs)

Cyclo-oxygenase-2 (COX-2) inhibitors

Trimethoprim and trimethoprim-containing combination products, such as Bactrim®
and Septra® (trimethoprim/sulfamethoxazole fixed combination)

Herbal Supplements: 

For example, Noni juice, alfalfa (Medicago sativa), dandelion (Taraxacum 
officinale), horsetail (Equisetum arvense), nettle (Urtica dioica), milkweed, lily 
of the valley, Siberian ginseng, hawthorn berries


Assess patient for dehydration or any condition that could lead to dehydration (e.g., 
diarrhea, vomiting) and/or hypovolemia and initiate appropriate corrective measures of


If serum potassium remains > 5.3 and ≤ 5.5 mmol/L (mEq/L), regularly monitor serum 
potassium levels to ensure stability (suggested once monthly)

Consider down-titration of study drug, according to investigator’s medical judgment.
Serum potassium greater than 5.5 and less than 6.0 mmol/L (mEq/L)

Confirm potassium concentration in a non-hemolyzed sample

Consider down-titration or temporarily discontinue study drug according to investigator 
medical judgment.

Apply all measures outlined for serum potassium > 5.3 and ≤ 5.5 mmol/L

Repeat serum potassium measurement after 2-3 days

If serum potassium < 5.5 mmol/L, consider resumption of study drug at lower dose with 
repeat potassium within 5 days
Serum potassium greater than or equal to 6.0 mmol/L (mEq/L)

Immediately discontinue study drug

Confirm potassium concentration in a non-hemolyzed sample

Urgently evaluate patient and treat hyperkalemia as clinically indicated

Apply all measures outlined for serum potassium > 5.3 and < 6.0 mmol/L (mEq/L)
No resumption of study drug without individualized case discussion with and permission from 
Novartis medical monitor or his/her designee.

Appendix 4: Guidelines for the management of blood pressure
Guidelines
1. Investigator should monitor BP closely
2. If symptomatic hypotension occurs: 
a. Correct any treatable cause, e.g. hypovolemia
b. If hypotension persists, any antihypertensive drug such as diuretics, calcium channel 
blockers (CCBs), nitrates, beta blockers, aldosterone antagonists and α-blockers, 
should be down-titrated or stopped first before down-titration of the study drug is 
considered. Any non-antihypertensive drug (such as nitrates) should be considered for 
down-titration prior to study drug as determined by the best judgment of the 
investigator.
c. If hypotension persists, the study drug should be down-titrated or even temporarily 
withdrawn. The dose re-challenge and medications adjust guidelines described in 
Section 6.5.2 should be adhered to as much as possible.

Appendix 5: Guidelines for the management of renal dysfunction
General principles:Glomerular filtration rate in HF patients depends on intrinsic renal function 
and on a balance between afferent and efferent glomerular arterial tonicity. This tonicity is 
partly regulated by astimulation of angiotensin II and could be affected by either study drug. 
Moreover, renal dysfunction may develop or may deteriorate in some patients after study drug 
administration. These recommendations have been developed to guide the investigators in 
managing patients with renal dysfunction after randomization.
Two types of response to serum creatinine increase are described:
Surveillance situationIf, at any time in treatment period, eGFR decreases by ≥25% from 
baseline (Visit 101) (or if serum creatinine concentration increase to 2.5 mg/dL [221 μmol/L]), 
the investigator will check for potentially reversible causes of renal dysfunction such as:

Non-steroidal anti-inflammatory drug intake, antibiotics, or other treatments known to 
affect creatinine

Volume decrease, including that resulting from excessive dosing of diuretics

Urinary infection

Urinary tract obstruction

Study drug
Action situation
If a patient’s eGFR decreases by ≥40% from baseline (Visit 101) (or if serum creatinine 
concentration rises above 3 mg/dL (265μmol/L), the investigator will check for potentially 
reversible causes of renal dysfunction (see above).
The investigator may consider down-titration of study drug. If the investigator judges that study 
drug has to be stopped, he/she will have to contact the Novartis medical monitor or his/her 
designee. Thereafter, serum creatinine assessments will have to be repeated at least each week 
until levels return to acceptable values. If study drug was stopped, every effort will be done to 
restart it again, according to clinical conditions.
