Introduction
Inclisiran (also referred to as KJX839) is a novel synthetic ribonucleic acid (RNA) interference 
(RNAi) therapeutic, Inclisiran (CKJX839) for Injection (subcutaneous [SC] use), formerly 
referred to as ALN-PCSSC, for the treatment of hypercholesterolemia. This protocol describes a 
study to evaluate and compare the effect of inclisiran treatment on low density lipoprotein 
cholesterol (LDL-C) levels at Day 210 with evolocumab (REPATHA®). This study is sponsored 
by Novartis and  will be conducted in compliance with Good Clinical Practices (GCP) including 
the Declaration of Helsinki and all applicable regulatory requirements.
1.1
Background
1.1.1
Disease Overview
According to the World Health Organization (WHO), atherosclerotic cardiovascular disease 
(ASCVD), comprised mainly of coronary heart disease (CHD) and stroke, is the leading cause of 
death worldwide, resulting in 17 million deaths annually (WHO Cardiovascular Statistics, 2011). 
Data from the INTERHEART case-control study estimates that 45% of myocardial infarctions 
(MI) in Western Europe and 35% of myocardial infarctions in Central and Eastern Europe are 
due to abnormalities in blood lipids (Yusef et al, 2004). Hypercholesterolemia, specifically, 
elevated LDL-C, is one of the major risk factors for the development of CHD, the leading cause 
of death worldwide (Grundy et al, 2004; Go et al, 2014). The continuous and graded relationship 
between plasma LDL-C concentration and CHD risk is such, based upon data  a large body of 
epidemiological and clinical studies, for every 0.78 mmol/L (30 mg/dL) change in LDL-C, the 
relative risk for CHD changes by approximately 30% (Grundy et al, 2004). In addition, multiple 
clinical trials have demonstrated a decreased risk of cardiovascular mortality and morbidity in 
patients on statin therapy of around 5 to 6% for every 10 mg/dL reduction in LDL-C (Delahoy et 
al, 2009; Baigent et al, 2010). High dose statin treatment has also been shown to result in 
additional clinical benefit compared to low or moderate dose statin treatment (Cannon et al, 2004; 
Pedersen et al, 2005). Despite the extensive use of statins, current therapies for the management 
of elevated LDL-C remain inadequate in some patients. This is particularly true in patients with 
pre-existing CHD and/or diabetes or a history of familial hypercholesterolemia (FH), who are at 
the highest risk and require the most aggressive management (Davidson et al, 2005). Among these 
high risk subjects, less than 50% achieved the target LDL-C goal of <2.6 mmol/L (100 mg/dL) 
following 6 months of statin treatment, despite close monitoring and drug regimen optimization 
(Foley et al, 2003; Baigent et al, 2005; Kearney et al, 2008; Foody et al, 2010). Thus, there is a 
clear unmet medical need for new drugs to lower LDL-C, especially in certain patient populations 
such as FH.
1.1.2
PCSK9 Biology and Target Rationale
Proprotein convertase subtilisin kexin type 9 (PCSK9) is a member of the subtilisin serine 
protease family. Proprotein convertase subtilisin kexin type 9 is predominantly expressed by the 
liver and is critical for the down regulation of hepatocyte low-density lipoprotein receptor (LDLR) 
expression (Mousavi et al, 2009). LDL-C levels in plasma are markedly elevated in humans with 
gain of function mutations in PCSK9, classifying them as having severe familial 
hypercholesterolemia (Abifadel et al, 2003). Data from genetic association studies have identified 
loss of function alleles in human PCSK9 that result in lower PCSK9 protein levels and lower

Amended Protocol Version No. 05 Clean
Protocol No. MDCO-PCS16-01(CKJX839A12201E1)
LDL-C levels (Zhao et al, 2006; Hooper et al, 2007; Horton et al, 2009). In one published study, 
heterozygous individuals (carrying a single copy of a loss of function PCSK9 mutation) had 
significantly lower LDL-C with median levels of approximately 70 mg/dL (1.81 mmol/L) (Cohen 
et al, 2006). Over a 15-year period of retrospective data analysis, this sustained lowering in       
LDL-C levels translated to an 88% lower risk of risk for CHD. Follow-up publications describe 
two adult individuals that are compound heterozygous for loss of function alleles of PCSK9. 
These individuals lack detectable plasma PCSK9 protein, have LDL-C levels ≤20 mg/dL, and yet 
are otherwise healthy (Zhao et al, 2006; Hooper et al, 2007). Additionally, recent human clinical 
trials with PCSK9 blocking antibodies have shown significant lowering of LDL-C in healthy 
volunteers and across a range of high cardiovascular (CV)-risk populations and with elevated 
LDL-C both with and without statins (Banerjee et al, 2012; Dias et al, 2012; Milazzo et al, 2012; 
Raal et al, 2012; Roth et al, 2012; Stein et al, 2012; Sullivan et al, 2012; Hooper et al, 2013). Thus, 
the overall scientific and clinical data suggests that PCSK9 is a well-validated drug target whose 
inhibition results in significant LDL-C lowering without otherwise negatively impacting overall 
health most recently culminating in the approval (in Europe and North America) of two 
monoclonal agents to inhibit PCSK9.
1.1.3
Mechanism of RNA Interference
Ribonucleic acid interference (RNAi) is a naturally occurring cellular mechanism for regulating 
gene expression that is mediated by small interfering RNAs (siRNAs). Typically, synthetic 
siRNAs are 19-base to 25-base pair double-stranded oligonucleotides in a staggered duplex with 
a two- to four-nucleotide overhang at one or both of the 3’ ends. Such siRNAs can be designed 
to target an endogenous messenger RNA (mRNA) transcript of a given gene. When introduced 
into cells, the guide (or antisense) strand of the siRNA loads into an enzyme complex called the 
RNA-Induced Silencing Complex. This enzyme complex subsequently binds to its 
complementary mRNA sequence, mediating cleavage of the target mRNA and the suppression of 
the target protein encoded by the mRNA (Elbashir et al, 2001).
Since unmodified siRNAs are rapidly eliminated and do not achieve significant tissue distribution 
upon systemic administration (Soutschek et al, 2004), various formulations are currently used to 
target their distribution to tissues, and to facilitate uptake of siRNAs into the relevant cell type. 
One approach that has been used successfully in vivo, in animal models (including in rodents and 
nonhuman primates) and humans employs intravenous delivery of siRNA in lipid nanoparticle 
(LNP) formulations (Soutschek et al, 2004; Morrissey et al, 2005; Geisbert et al, 2006; Judge et 
al, 2006; Zimmermann et al, 2006; Coelho et al, 2013; Tabernero et al, 2013). Another approach 
for liver-specific gene silencing is subcutaneously administered siRNA conjugated to a 
N-acetylgalactosamine (GalNAc) carbohydrate ligand (Ashwell and Morell, 1974). Conjugation 
of a triantennary GalNAc ligand to an siRNA enables hepatocyte binding and subsequent cellular 
uptake via the asialoglycoprotein receptor, resulting in engagement of the RNAi pathway and 
down regulation of hepatic proteins. Single and multiple doses of subcutaneously administered 
siRNA-GalNAc conjugates have been used to target transthyretin (TTR) mRNA for the treatment 
of TTR-mediated amyloidosis. ALN-TTRCSC has been found to be generally safe and well 
tolerated in Phase I and Phase II clinical trials in over 40 healthy volunteers and 18 subjects with 
familial amyloidotic cardiomyopathy and senile systemic amyloidosis (ALN-TTRSC-001; 
EudraCT 2012-004203-12; and ALN-TTRSC-002; EudraCT 2013-002856-33).

1.2
Inclisiran , an RNAi Therapeutic for Hypercholesterolemia
Inclisiran for Injection (SC use) is comprised of the PCSK9 siRNA, ALN-60212, formulated in 
phosphate buffer. The PCSK9 siRNA is a chemically synthesized double stranded 
oligonucleotide covalently linked to a ligand containing GalNAc residues. This synthetic 
investigational RNAi therapeutic has been designed to suppress the liver production of PCSK9 
when administered via SC injection. Inhibition of PCSK9 synthesis through an RNAi mechanism 
has the potential to lower tissue and circulating plasma PCSK9 protein levels, resulting in higher 
expression of LDLR in the liver, and consequently lower LDL-C levels in the blood stream. The 
initial proposed indication for inclisiran is the treatment of subjects with hypercholesterolemia 
who are not achieving therapeutic LDL-C goals despite maximally tolerated lipid-lowering 
therapy, or for subjects who are intolerant of statins.
1.2.1
Preclinical Studies
The pharmacology, metabolism, pharmacokinetics (PK), and toxicology of inclisiran were 
evaluated in a series of in vitro and in vivo nonclinical studies. Development and reproductive 
toxicology studies have not been conducted.
The results of the pharmacology studies show that inclisiran exhibited dose-dependent sustainable 
suppression of PCSK9 protein that was paralleled by lowering of serum LDL-C with the same 
kinetics. The time to reach PCSK9 nadir was approximately 20 days and the mean maximal 
PCSK9 and LDL-C inhibition was 93% and 74%, respectively.
Off-target analysis encompassing bioinformatics and tissue culture assays indicate a very low 
likelihood of inclisiran affecting heterologous gene transcription, thereby decreasing the potential 
of untoward side effects. In a cardiovascular and respiratory study in telemetered conscious 
cynomolgus monkeys, inclisiran had no immediate or delayed effects on clinical observations, 
qualitative or quantitative electrocardiogram (ECG) parameters, hemodynamic parameters, 
respiration rate, or body temperature at any dose level.
Pharmacokinetic studies showed that inclisiran is very well absorbed following SC administration. 
Inclisiran has a short plasma half-life (range: 1 to 4 hours) and preferentially distributes to the 
liver, its target organ, achieving Tmax levels within 8 hours of administration. With the exception 
of the kidney which is the main route of elimination, liver concentrations of inclisiran are many 
fold higher than other tissues examined, thereby reducing the potential for off-target toxicity. In 
addition, studies with heart tissue showed that very low levels of inclisiran are internalized and it 
does not associate with the ribonucleic acid-induced silencing complex indicating a low 
likelihood of activity in heterologous tissues.
The results of repeat dose toxicology studies in rats and monkeys show that inclisiran was well 
tolerated. The most consistent findings were the presence of vacuolation in hepatocytes of rats 
and lymph node macrophages of monkeys and basophilic granules in hepatocytes of monkeys 
and renal tubule epithelium of rats. The presence of vacuolation, particularly in the liver, and 
basophilic granules in the kidney are not associated with changes in clinical pathology parameters 
including liver function enzymes and urinalysis parameters signifying that the vacuolation and 
basophilic granules are not adverse toxicological findings. In addition, there are indications that 
these findings are reversible.

Inclisiran was tested in a series of in vitro and in vivo genetic toxicology studies, including a 
bacterial mutagenicity assay, an in vitro chromosome aberration assay using human peripheral 
lymphocytes, and an in vivo bone marrow micronucleus assays in rats. There were no gene 
mutations or chromosomal damage observed in any study. Therefore, inclisiran is not genotoxic.
Further information is in the Investigator’s Brochure (IB).
1.2.2
Clinical Studies
One Phase I study has been conducted to date (Study ALN-PCSSC-001). This was a randomized, 
single-blind, placebo-controlled, single-dose escalation and multiple-dose study of inclisiran 
administered SC to subjects with elevated LDL-C. The study was conducted in two phases: a 
single ascending dose (SAD) phase and a multiple dose (MD) phase. During the SAD phase, 
24 subjects were assigned to either receive placebo or one of five doses of inclisiran ranging from 
25 mg to 800 mg. Those who received doses of at least 100 mg saw their LDL-C drop at least 
40%; at the 500 mg dose, LDL-C levels dropped as much as 78%. At 140 days after the treatment 
was given, subjects still had an average LDL-C reduction of about 40%.
In the MD phase, 45 subjects received multiple doses of either inclisiran (125mg weekly x4, 
250 mg biweekly x2, 300 mg and 500 mg twice given 1 month apart) or placebo. These subjects 
had maximal LDL-C reductions of 80% and average LDL-C reductions of 50% to 60%. To date, 
the drug appears to be generally safe and well tolerated. One subject on statin comedication had 
elevated liver enzymes with alanine aminotransferase (ALT) >4x the upper limit of normal (ULN), 
which resolved on stopping the statin.
One Phase II dose finding study CKJX839A12201 (MDCO-PCS-15-01; ORION-1) was 
conducted and is complete. This study was a placebo-controlled, double-blind, randomized trial 
to compare the effect of inclisiran administered SC as either a single dose (200 mg, 300 mg, or 
500 mg) on Day 1 or as two doses (100 mg, 200 mg, or 300 mg) on Day 1 and Day 90 in subjects 
with high cardiovascular risk and elevated LDL-C. A total of 501 subjects were randomized 
(placebo=127 and inclisiran=374) and 497 received at least one dose of study drug (placebo=127 
and inclisiran=370). After administration of dosing, all subjects were followed until Day 210. 
Subjects whose LDL-C values had not returned to within 20% of the change from their baseline 
value were followed up to Day 360. Regular reviews of safety were performed by an independent 
Data Monitoring Committee and no safety concerns were reported and no changes to the protocol 
were requested during conduct of the study.
An interim analysis was performed after all subjects had completed the Day 90 visit in order to 
select the dose for subsequent studies. Inclisiran was generally well tolerated following single and 
multiple dosing. There was no imbalance observed in the incidence or type of AEs and serious 
adverse events (SAEs) across the dose range of inclisiran groups with a similar incidence to 
placebo. The majority of adverse events (AEs) were mild or moderate in severity. The most 
common AEs observed after the first injection until Day 90 were myalgia, back pain, fatigue, 
headache, dizziness, nasopharyngitis, diarrhea and hypertension. A low incidence of mild, 
localized, injection site reactions (ISRs) was reported with no clear dose dependent or cumulative 
effect observed following first or second injection. No subjects developed treatment emergent 
liver findings that met the laboratory definition of Hy's Law. One subject developed clinically 
significant changes in liver function tests reported as an SAE which was attributed to concomitant 
statin therapy and a recent statin dose increase and resolved on discontinuation of statin. All doses

Amended Protocol Version No. 05 Clean
Protocol No. MDCO-PCS16-01(CKJX839A12201E1)
of inclisiran inhibited PCSK9 synthesis and lowered LDL-C significantly. One dose of 300 mg 
inclisiran achieved a mean 51% LDL-C reduction. Two doses of 300 mg inclisiran achieved a 
mean 57% LDL-C reduction in LDL-C. The LDL-C reduction was significant and durable out 
to 180 days following either one or two injections of inclisiran. No additional LDL-C reduction 
was observed with 500 mg as a single dose. Potentially favorable changes were also observed in 
the overall atherogenic lipid profile. 
The end of trial evaluation confirmed the data observed at the interim analysis. Inclisiran, at all 
tested doses, was safe and well-tolerated in subjects at high cardiovascular risk who had elevated 
LDL-C levels. A single dose of 300 mg inclisiran sodium achieved a maximum mean LDL-C 
reduction of 50.9% at Day 60. Two 300 mg inclisiran sodium doses administered at Day 1 and 
Day 90 achieved a maximum mean LDL-C reduction of 55.5% at Day 150. The LDL-C reduction 
was clinically significant and durable out to 360 days following either one or two injections of 
inclisiran. Maximum PCSK9 reduction was observed at the 300 mg dose level. A similar 
reduction observed in LDL-C at Day 270 compared to Day 90 along with the time adjusted mean 
LDL-C reduction of 50.5% over this time interval further support a dose regimen of 300 mg 
inclisiran sodium given at Day 1, Day 90, and every 6 months thereafter as the optimal dose and 
dose regimen to investigate further in subsequent Phase III clinical studies. Modeling and 
simulation analyses provide further support for the proposed 6 monthly maintenance regimen.
No persistent and clinically relevant treatment related abnormalities were reported in any 
laboratory parameter. A low incidence of AST, ALT and CK rises were reported, although some 
of these subjects also had elevated baseline value or underlying medical conditions contributing 
to these elevations. There were no treatment emergent increases in bilirubin from a normal 
baseline and no case met the definition of Hy’s Law. One subject had a rise in ALT on Day 104 
following the second injection of 300 mg inclisiran sodium as reported in the interim analysis. 
This was considered related to a recent increase in the dose of statin and resolved immediately on 
stopping the statin. There were no clinically relevant or persistent changes in the inclisiran dose 
groups observed in any other laboratory parameters including renal function, hemoglobin, 
platelets, HbA1c and coagulation parameters and no clinically relevant differences from placebo.
Subjects participating in MDCO-PCS-15-01 (CKJX839A12201) were asked to consent to the 
ORION-3 trial described in this protocol (MDCO-PCS-16-01 (CKJX839A12201E1)) once their 
lipid levels have returned to within 20% of the baseline levels or after they reached the Day 360 
visit in study MDCO-PCS-15-01, whichever occured first.
1.2.3
Known and Potential Risks and Benefits
Subjects taking part in this clinical study will receive guideline recommended standard of care as 
background therapy (including maximally-tolerated statin therapy and/or other LDL-C lowering 
therapies) when administered inclisiran or comparator. Reduction of LDL-C has been associated 
with reduced CV risk both by epidemiology and in controlled clinical trials. Injection site reaction 
is the only event known to be attributed to inclisiran treatment. The safety profile of inclisiran 
observed to date is considered acceptable for this clinical trial. Evolocumab is an approved drug 
with a good safety profile, but may cause allergic reactions.
An expanded risk-benefit summary is provided in the current/approved version of the 
Investigator’s Brochure.

MDCO-PCS-15-01. In countries where applicable, on signing consent and being entered into this 
study, the investigator will be informed by the IXRS regarding the treatment allocation, and 
therefore, whether placebo or inclisiran was administered in study MDCO-PCS-15-01 
(CKJX839A12201) and the subject will be informed accordingly. Those subjects who received 
inclisiran in MDCO-PCS-15-01 will receive inclisiran sodium throughout this study (Group 1; 
inclisiran only arm), and those subjects who received placebo in MDCO-PCS-15-01 
(CKJX839A12201) will receive evolocumab as comparator for 1 year, and then transition to 
inclisiran for the remainder of the study (Group 2; switching arm). Until study drug is available, 
subjects will have monthly observation visits until study drug administration commences.
Day 1 of ORION-3 is the day when eligible subjects will receive the first SC administration of 
inclisiran or evolocumab.
Group 1 (Inclisiran Only Arm):
After first study drug administration of inclisiran, all subjects will be observed in the clinic for at 
least 4 hours post injection before being discharged.
The subsequent visit schedule is as follows:

Dosing visits: Every 180 days until Day 720, an additional dose on Day 810, then back to
every 180 day dosing until EOS. Therefore, dosing after Day 1 (ORION-3) will occur on 
Days 180, 360, 540, 720, 810*, 990, 1170 and 1350.
*Day 810 dose added to assess the effect of giving 2 doses 90 days apart (at Days 720 and 
810).

Safety follow-up visits: Days 30, 90, 210, 270, 390, 450, 570, 630, 870, 1080, 1260, and 
EOS (Day 1440).
Group 2 (Switching Arm):
Subjects receiving evolocumab will receive the first dose on Day 1 (ORION-3), administered by 
the investigator, and will then self administer evolocumab at home every 14 days until Day 336.  
Sites will then be assigned to have their evolocumab treated patients placed into one of two 
transition groups.

Transition 1 (staged): Day 336 will be the final dose of evolocumab therapy and the first 
dose of inclisiran will be administered at the Day 360 visit.

Transition 2 (concurrent): Day 336 will be the final dose of evolocumab therapy at home. At 
the Day 360 visit subjects will receive an additional dose of evolocumab and their first dose 
of inclisiran, both administered by the investigator.
After first study drug administration of inclisiran on Day 360, all subjects in Group 2 (switching 
arm) will be observed in the clinic for at least 4 hours post injection before being discharged.
The subsequent visit schedule is as follows:

Dosing visits: Day 450 (2nd dose), then every 180 days until end of study (Days 630, 810, 
990, 1170 and 1350).

Safety follow-up visits: Days 390, 510, 540, 720, 900, 1080, 1260, and EOS (Day 1440).

Withdrawal Criteria
All subjects have the right to withdraw at any point during treatment without prejudice. The 
investigator can discontinue any subject at any time if medically necessary. It will be documented 
whether or not each subject completed the clinical study. If for any subject study treatment or 
observations were discontinued, the reason will be recorded and the Sponsor should be notified 
promptly. Reasons that a subject may discontinue participation in a clinical study are considered 
to constitute one of the following:

AE

Death

Subject withdrew consent

Physician decision


It is especially important that all subjects be contacted to attend the Day 210 visit, as it is the 
primary endpoint of the study. .Subjects discontinuing participation in this trial should be 
encouraged to complete the EOS visit except for those subjects who specifically withdraw consent. 
All data collected up until the time of subject withdrawal is to be entered into the electronic case 
report form (eCRF).Any withdrawn subjects will not be replaced in this study.
4.4.1
Withdrawal from Study Medication
In the event a subject withdraws or is withdrawn from the study medication, the investigator will 
inform the Medical Monitor and the Sponsor immediately. If there is a medical reason for 
withdrawal, the subject will remain under the supervision of the investigator for protocol-
specified safety follow up procedures.  
4.4.2
Individual Subject Dosing Stopping Criteria
Subjects will have clinic visits at regular intervals. The following individual dosing stopping 
criteria will be followed:
1. Dosing with study medication (inclisiran or evolocumab) may be temporarily discontinued 
or stopped for intolerable AEs, or if the Investigator believes that continuing dosing will be 
detrimental to the subject’s mental or physical health. This includes severe or serious 
reactions at the injection site and any anaphylactic type reactions.
2. Subjects with persistent and unexplained increases in transaminases (ALT or AST) >3x 
ULN or with bilirubin increases >2x ULN from a normal baseline on two consecutive 
occasions at least 4-7 days apart by repeat test must be discontinued from study treatment

by qualified clinical study site staff under the supervision of the investigator or designee. The site 
of injection is the abdomen. Do not inject into areas of active skin disease or injury such as 
sunburns, skin rashes, inflammation, tattoos or skin infections.
If a local reaction around the injection site occurs, photographs of the injection site should be 
obtained, if possible, at first presentation and at each of the follow-up visits until the injection site 
reaction resolves. Detailed instructions for study drug administration are found in the Pharmacy 
Manual.
5.1.2
Comparator Drug (evolocumab)
Evolocumab will be administered as a single SC injection at a dose and frequency as per the label 
of the approved therapy. Training for self administration will be provided by site personnel 
according to the label, and the first dose will be injected under supervision of the Investigator or 
designee. Subjects will be required to self administer evolocumab every 14 days until Day 336. 
For subjects in Transition 2, an additional dose of evolocumab, the final dose, will be administered 
at the Day 360 visit by the investigator and these subjects will also receive their first inclisiran 
injection at the same visit. The investigator (or designee) should use different sites of injection 
when administering these two products (evolocumab and inclisiran) at the same time. Do not 
inject into the same area of the skin.
Evolocumab, a monoclonal antibody directed towards PCSK9, is a sterile, clear to opalescent, 
colorless to pale yellow solution available as a 140 mg/mL solution in a single-use prefilled 
syringe or SureClick® autoinjector. Evolocumab is indicated as an adjunct to diet and maximally 
tolerated statin therapy for the treatment of adults with heterozygous familial 
hypercholesterolemia (HeFH) or clinical atherosclerotic cardiovascular disease (CVD), who 
require additional lowering of low density lipoprotein cholesterol (LDL-C). The recommended 
subcutaneous dosage of evolocumab in patients with HeFH or patients with primary 
hyperlipidemia with established clinical atherosclerotic CVD is 140 mg every 2 weeks.
5.1.3
Packaging and Labeling
Inclisiran for Injection will be provided by the sponsor. Medication labels will comply with 
regulatory requirements. The storage conditions for each medication provided will be described 
on the medication label.
The Inclisiran for Injection (subcutaneous use) is packaged in a glass vial containing 300 mg 
(equivalent to 284 mg inclisiran) per 1.5 mL. The container closure system consists of a Type I 
glass vial, a Teflon-faced bromobutyl 13 millimeter stopper, and a flip off Truedge aluminum 
seal.
Evolocumab will be provided as prefilled pens, as locally approved.
5.1.4
Storage
Inclisiran for Injection will be stored at room temperature [up to 25°C (77°F)] as specified in the 
Pharmacy Manual. Access should be strictly limited to the investigator, pharmacists, and their 
designees. No special procedures are required for the safe handling of Inclisiran for Injection.
Evolocumab will be used according to its approved label. Evolocumab should be kept in the 
refrigerator and allowed to warm to room temperature for at least 30 minutes before use.

Alternatively, evolocumab can be kept at room temperature [up to 25°C (77°F)] in the original 
carton, but under these conditions, it must be used within 30 days.
5.1.5
Accountability
The investigator or designee must maintain an inventory record of study drugs received and 
administered to assure the regulatory authorities and the Sponsor that the investigational new drug 
will not be dispensed to any person who is not a subject under the terms and conditions set forth 
in this protocol. Drug accountability forms and/or specific instructions can be found in the 
Pharmacy and Comparator Manuals.
The study drug supplied for use in this study is to be prescribed only by the principal investigator 
or designated subinvestigators and may not be used for any purpose other than that outlined in 
this protocol.
During the study, all used study drug containers (eg, empty vials/bottles) will be kept until the 
monitor has reviewed the accountability records.
All unused study drug will be destroyed on site (or returned to the packaging and labeling facility 
for destruction if destruction on site is not possible) once the study drug has been inventoried and 
the monitor has reviewed the accountability records. In the event that study drug(s) needs to be 
returned for any other reason, the site will receive a written request listing the drug lot number(s) 
to be returned and the reason for the return request.

The expected duration of the subjects’ involvement in the study will be approximately 4 years, 
which includes consent, study drug administration, and follow-up through the EOS visit (final 
visit which occurs 90 days following the final administration of study drug, or at least 30 days 
following the final administration of study drug if the study ends early or if the subject 
discontinues the study early).
At each visit, LDL-C levels, AEs, SAEs, concomitant medications, vital signs, and safety 
laboratory assessments will be collected.
6.1
Schedule of Events/Assessments
If the COVID-19 pandemic limits or prevents on-site study visits, alternative methods of 
providing continuing care may be implemented. Phone calls or remote/virtual contacts (e.g. 
teleconsult) can replace on-site study visits, for the duration of the pandemic until it is safe for 
the participant to visit the site again.  Also, the visits window has been extended to +/-2 months 
during the pandemic.

General Conduct of the Study
On completion of study MDCO-PCS-15-01 (ORION-1), eligible subjects will be consented for 
this study. Written informed consent will be obtained for this study by the principal investigator 
or sub-investigator from all subjects before the performance of any protocol-specific procedure. 
In countries where applicable, on signing consent and being entered into this study, the investigator 
will be informed by the IXRS regarding the treatment allocation, and therefore, whether placebo 
or inclisiran was administered in study MDCO-PCS-15-01 and the subject will be informed 
accordingly.
Until study drug is available subjects will attend a basic visit for safety and concomitant 
medications at 30 day intervals. Once study drug is available, eligible subjects will receive a single 
injection of study drug on Day 1 (ORION-3).
Note: Data on medical history and concomitant medications will be reported from Baseline of 
ORION-1. Details will be described in the Statistical Analysis Plan (SAP).

Treatment and Follow-Up Visits
All subjects will return to the study center 30 days (± 2 days) after first study drug administration 
for Follow-Up Visit 1 and after 90 days (± 7 days) for Follow-Up Visit 2.
Group 1 (inclisiran only arm) subjects will return at Day 180 (± 7 days) for their second study 
drug administration of inclisiran, and then at 30 and 90 days after each subsequent study drug 
administration of inclisiran.

Dosing visits will take place on Days 180, 360, 540, 720, 810, 990, 1170 and 1350.

Safety follow-up visits will occur on Days 30, 90, 210, 270, 390, 450, 570, 630, 870, 1080, 
1260, and EOS (Day 1440).
Group 2 (switching arm) subjects will return to the study center at Days 180, 210, 270 for study 
related procedures. At Day 360 visit, subjects in Group 2 (switching arm) are assigned to either 
Transition 1 (staged) or Transition 2 (concurrent) (see Section 3.1).
Study drug administration of inclisiran and safety follow-up visits for both Transition 1 (staged) 
and Transition 2 (concurrent) will occur as follows:

Dosing visits will take place on Day 360 (first dose of inclisiran), Day 450, Day 630, 810, 
990, 1170, and 1350.

6.6.2
Treatment & Follow Up Visits After Day 360
Refer to Section 6.6 for the schedule of follow-up visits and the assessments to be completed 
following the Day 360 transition visit to inclisiran.
6.7
Unscheduled Visit
If deemed necessary by the Investigator, subjects may attend an unscheduled visit at the clinic. 
These visits are not part of the protocol per se and will not be recorded in the eCRF but should be 
noted in the subject’s medical notes.
6.8
End of Study Visit
Subjects will receive study drug for approximately 4 years (or until the investigator's 
recommendation of discontinuation, sponsor's recommendation of discontinuation, the subject's 
decision to discontinue for any reason, or until an administrative decision is made to end the study). 
Regardless of treatment arm (inclisiran or evolocumab), the EOS visit will be the final safety 
follow-up visit which occurs 90 days (at Day 1440) following the final administration of study 
drug. However, if the study ends early or if the subject discontinues the study, the EOS visit should 
occur at least 30 days following the final administration of study drug.
If subjects, who have completed the EOS (90 days after last dosing), wish to continue treatment 
with inclisiran (and no decision or recommendation was made to discontinue the trial) they will be 
given the opportunity to enroll into ORION-8 (open-label extension trial) 
A subject’s participation in the study is complete when:

All ongoing SAEs have been followed to resolution or stabilization (Section 5.3.1) and 

The following procedures/assessments have been completed: 
-
Vital signs: blood pressure and heart rate 
-
Physical examination (including weight and full neurological examination as described in 
(APPENDICX A)
-
12-lead ECG
-
Central laboratory assessments (hematology, chemistry and coagulation testing)

adverse subject outcomes for regulatory reporting purposes. A severe AE need not 
necessarily be considered serious and a serious AE need not be considered severe. For 
example, nausea that persists for several hours may be considered severe nausea, but not an 
SAE. On the other hand, an MI that may be considered minor could also be an SAE if it 
prolonged hospitalization.
8.1.3
Special Situations Events
Information that is not necessarily considered an adverse event but which can possibly contribute 
to the overall knowledge concerning the safety of the compound will be considered a special 
situation event (Section 8.2.4).
8.2
EVALUATING ADVERSE EVENTS
8.2.1
Pre-existing conditions 
Planned hospital admissions and/or surgical operations for an illness or disease that existed at 
baseline and did not aggravate during the study are not to be reported as AEs.
8.2.2
AE Severity
The severity of every AE must be assessed by the investigator using a three-point grading system.
1 = Mild: Discomfort noticed, but no disruption to daily activity. Requires minimal or no treatment.
2 = Moderate: Discomfort sufficient to reduce or affect normal daily activity. Requires therapeutic 
measures.
3 = Severe: Inability to work or perform normal daily activity. May require systemic drug therapy 
or other treatment.
8.2.3
Relationship to Study Drug
The relationship of an AE to study treatment will be assessed by using a binary assessment. The 
investigator should determine whether there is a ‘Reasonable possibility’ or ‘No reasonable 
possibility’ that the study product caused the event based on the definitions below.
Reasonable possibility - There is a reasonable possibility that the administration of the study 
product caused the AE. There is evidence to suggest a causal relationship between the study 
product and the AE. 
No reasonable possibility - There is no reasonable possibility that the administration of the study 
product caused the AE. There is no temporal relationship between the study product and event 
onset, or an alternative etiology has been established.
8.2.4
Requirements for Additional Safety Data Collection
8.2.4.1
Special Situations
Special Situations designated for this study are the following:

Medication errors that fall into the following categories:

Novartis

Page 51 of 69
Amended Protocol Version No. 05 Clean
Protocol No. MDCO-PCS16-01(CKJX839A12201E1)

wrong subject (ie, not administered to the intended patient)/wrong study product 
(inclisiran vs evolocumab)

wrong dose (including overdose, underdose, change in dosing regimen, strength, form, 
concentration, amount);

wrong route of administration

accidental exposure 

Pregnancy/lactation exposures with or without any AEs related to the parent or child 

Suspected transmission via a medicinal product of an infectious agent 

Drug interactions 
8.2.4.2
Other Safety Related Information
Injection site reactions (ISR) including individual signs or symptoms at the injection site following 
investigational product administration should be recorded on specifically designed eCRF pages.
Photographs of ISR, if they were obtained during the study visits, should be forwarded to study 
inbox.
Other safety related information that requires collection, evaluation and reporting safety 
information in this study are:

Abnormal neurological examination, eg, peripheral sensory and motor evaluation, an 
assessment of gait, pain, position, strength and reflexes (APPENDICX A).

Potential anaphylactic reactions assessed by Sampson criteria (APPENDIX B). If Sampson 
criteria are positive, confirm by elevation of tryptase in blood plasma measured within 
30 minutes of symptoms.
Hyperglycemia-related AEs and medications initiated to control hyperglycemia will be collected 
at each follow-up visit. New onset of diabetes in subjects with no medical history of diabetes will 
be reported when:

HbA1C becomes ≥6.5% and/or

Two consecutive values of fasting plasma glucose that are ≥126 mg/dL
In the case that a new concomitant medication is added for control of plasma glucose, further 
information regarding the subject will be collected to assess for a diagnosis of new onset diabetes.
Report ‘Worsening of the glycemic control’ or ‘diabetic complications’ in subjects with a medical 
history of disease (HbA1C ≥6.5% at baseline) when:

HbA1C increases from Baseline (Day 1 of ORION-3) >0.5% and/or

New concomitant medication or increase in dose of current antidiabetic therapy is initiated to 
improve the control of plasma glucose level.
8.3
PROCEDURE FOR ADVERSE EVENT REPORTING
8.3.1
Serious Adverse Event Reporting
All SAEs that occur in subjects between Study Entry and Day 1, as well as in subjects assigned to 
inclisiran or evolocumab treatment from study Day 1 through the EOS visit must be reported to 

Novartis
Confidential
Page 52 of 69
Amended Protocol Version No. 05 Clean
Protocol No. MDCO-PCS16-01(CKJX839A12201E1)
the Sponsor’s Global Pharmacovigilance Department (GPV) within 24 hours of awareness of the 
event using the SAE/AESI Report Form designated to the ORION-3 study.
The completion and processing of the SAE/AESI Report Form should be per the instructions in 
the provided SAE/AESI Report Form completion guidelines. Each SAE/AESI must be recorded 
on the sources documents and entered on the appropriate page of the eCRF.
The investigator should provide any follow-up information for the event to the Sponsor on an 
updated SAE/AESI report form as soon as it becomes available. The Sponsor will contact the 
investigator, if necessary, to clarify any of the event information or request additional information.
Where appropriate, if required by local regulations or procedures, the investigator should report 
these events to the Institutional Review Board (IRB)/Ethics Committee (EC) and/or national 
regulatory authority in addition to the Sponsor.
8.3.2
Nonserious Adverse Event Recording
All nonserious AEs that occur in subjects between Study Entry and Day 1, as well as in subjects 
assigned to inclisiran or evolocumab treatment from study Day 1 up to EOS must be assessed and 
recorded on the source documents and eCRFs, regardless of causal relationship to the study drug.
8.3.3
Medication Error Reporting
Medication errors (with or without an associated AE) need to be recorded as medication errors in 
the eCRF.
Medication errors and an associated SAE need to be recorded in the eCRF and reported to the 
Novartis Safety department using SAE/SS Report Form as described in Section 8.3.1.
Medication errors and an associated nonserious AE need to be recorded in the eCRF as described 
in Section 8.3.2.
A mis-dosing protocol deviation (refer to Section 12.3) would need to be reported as a medication 
error if it was an “unintended error” as defined in Section 8.3.1.
8.3.4
Pregnancy Reporting
Occurrences of pregnancy in a study subject or study subject’s partner from study Day 1 through 
the EOS visit must be reported within 24 hours using the Pregnancy/Lactation Exposure Report 
Form.
In cases where a pregnancy occurs with a SAE, the SAE Report Form must be used to report the 
SAE and the Pregnancy Report Form must be used to report the pregnancy. When a pregnancy 
occurs without any concurrent SAE, the Pregnancy Report Form should be submitted alone. 
The pregnancy should be followed up to determine outcome, including spontaneous or voluntary 
termination, details of the birth, and the presence or absence of any birth defects, congenital 
abnormalities, or maternal and/or newborn complications. Newborns should be followed for 12 
months.

8.3.5
Reporting the Special Situations Events
The occurrence of the special situation events that are listed in Section 8.2.4 must be reported to 
the Novartis safety department using SAE/SS Report Form for the ORION-3 study. The SAE/SS 
Report Form should indicate that the reported event is the event of Special Situation.
The Special Situation events do not need to be serious to be reported.
8.4
Study Stopping Criteria
8.4.1
Data Monitoring Committee Stopping Rules
The DMC will use all available evidence and its collective judgment in making a recommendation 
to stop or modify the ORION-3 study for safety. Any statistical considerations are not a substitute 
for the committee’s medical, scientific, or statistical expertise.
8.4.2
Sponsor Discontinuation Stopping Criteria
The Sponsor will review data on an ongoing basis and may, on discussion with the DMC, terminate 
the study for any clinically significant drug related safety signal (eg, serious hypersensitivity 
reactions or drug induced liver injury, etc.).
Premature termination of a study may also occur because of a regulatory authority decision, change 
in opinion of the IRB/EC, drug safety problems, or at the discretion of Sponsor . In addition, 
Sponsor retains the right to discontinue development of inclisiran at any time.
If a study is prematurely terminated or discontinued, Sponsor will promptly notify the investigator. 
After notification, the investigator must contact all participating subjects and the hospital 
pharmacy (if applicable) within 30 days of the notification. Final study visits should occur within 
30 days of subject contact. As directed by Sponsor , all study materials must be collected and all 
care report forms (CRFs) completed to the greatest extent possible.
The Sponsor will inform the health authorities and the IRBs/EC that the study has been stopped 
and the reasons for doing so, within the locally applicable timelines.
9
Data Collection
An electronic data capture (EDC) system will be used for this study. All users will be trained on 
the technical features of the EDC as well as the content of the eCRF by qualified personnel prior 
to gaining access to the EDC. A UserID/Password will be granted after training. This ID is not to 
be shared amongst the study staff. All users must have a unique account to enter or review data. 
The eCRF should be filled out by the site 3 days after each visit. It is not expected that the eCRF 
will serve as source for any data collected in this study. If there is a reason for a site to do so, it 
must be approved by MDCO and documented in the site files.
This study will utilize the same EDC system used in the ORION-1 study to collect the data defined 
by this protocol, 
. Data already collected for medical history, 
ongoing concomitant medications, and ongoing adverse events will be retained and utilized in
analysis as defined by the SAP.
Prior to the database being locked, the investigator or designee will review, approve, and sign/date 
each completed eCRF. This signature serves as attestation of the investigator’s responsibility for 

Novartis

ensuring that all data entered into the eCRF are complete, accurate, and authentic. After the end of 
the study, a copy of the data will be provided to the site. This copy will contain the final data, an 
audit trail of activity on the data, and any queries and answers that were posted for data clarification.
For this study, the End of Study will be defined as the last visit of the last subject.

Statistical Plan
This study will be an open label, long term extension study with an active comparator 
(evolocumab), in approximately 490 subjects who have completed study MDCO-PCS-15-01 
(CKJX839A12201) (ORION-1), to evaluate the efficacy, safety, and tolerability of long-term 
Inclisiran injections.  The primary objective of this study is to evaluate the effect of inclisiran 
treatment on LDL-C levels at Day 210 compared to Baseline of ORION-1 in Group 1 (inclisiran 
only arm). A separate SAP document will provide more detailed specifications in data analysis 
and presentation.
10.1
Sample Size
This is an extension of the MDCO-PCS-15-01 (CKJX839A12201) (ORION-1) study. All eligible 
and willing subjects who have completed the ORION-1 study to at least Day 210 and whose     
LDL-C has returned to within 20% of the Baseline of ORION-1 value or who have reached Day 
360 can be enrolled into the ORION-3 study. Subjects withdrawn from the ORION-1 study at any 
time are not eligible for the ORION-3 study.
10.2
General Statistical Considerations and Definitions
10.2.1
General Statistical Methods
All study-collected data will be summarized by treatment group using descriptive statistics, graphs, 
and/or raw data listings. Categorical variables will be summarized using counts and percentages. 
Percentages are based on the number of subjects in the analysis set for whom there are nonmissing 
data, unless otherwise specified. Continuous variables, including changes from Baseline of 
ORION-1 or changes from Baseline (Day 1 of ORION-3), will be summarized using descriptive 
statistics (n, mean, standard deviation [SD], median and interquartile range [first and third 
quartiles], minimum and maximum).
A SAP will be written after finalizing of the eCRF and before database lock. The specifications in 
this document will detail the implementation of all the planned statistical analyses in accordance 
with the principal features stated in the protocol.
Note: Data on medical history and concomitant medications will be reported from Baseline of 
ORION-1. Details will be described in the Statistical Analysis Plan (SAP).
Statistical analyses will be carried out using SAS® statistical analysis software version 9.2 or 
higher (SAS® Institute, Inc., Cary, North Carolina, USA).

APPENDIX A
RECOMMENDED Neurological Examination
MOTOR FUNCTION 
When assessing motor function, from a neurological perspective, the assessment should focus on 
arm and leg movement. You should consider the following: 
1. Muscle size 
2. Muscle tone 
3. Muscle strength 
4. Involuntary movements 
5. Posture, gait 
Symmetry is the most important consideration when identifying focal findings. Compare one side 
of the body to the other when performing your assessment. 
Assessment of a Conscious Patient
Limb assessment of a conscious patient usually involves a grading of strength. 
Grade Strength 
Grade strength
Description
5
Full range of motion against gravity and resistance; normal muscle strength
4
Full range of motion against gravity and a moderate amount of resistance; slight 
weakness
3
Full range of motion against gravity only, moderate muscle weakness
2
Full range of motion when gravity is eliminated, severe weakness
1
A weak muscle contraction is palpated, but no movement is noted, very severe 
weakness
0
Complete paralysis
NB: In a conscious patient, the single best test to quickly identify motor weakness is the “drift 
test”. Have the patient hold their arms outward at 90 degrees from the body. With palms up, 
have the patient close their eyes and hold the arms for a couple of minutes. “Drifting” will 
occur if one side is weak. 
Lower Extremities
Assess the patient in a supine position. Ask him/her to separate both legs to test for hip abduction. 
Then ask the patient to bring the legs back together to test for hip adduction. Sit the patient on the 
side of the bed to assess knee flexion and extension. Ask the patient to flex and extend the knee. 
If able to do this, apply resistance as these movements are repeated. Test plantar and dorsiflexion 
by having the patient push down against your hand with their foot and then pull up against your 
hand with their foot. Remember to compare the left side to the right side. 
Upper Extremities
Assess ability to flex elbow (biceps) and straighten (triceps). Assess ability to raise shoulders and
return to a resting position. Assess wrist flexion and extension. Test each function with resistance. 
For focused upper extremity assessment, assess each digit for flexion, extension and lateral 
movement.

Assessment of an Unconscious Patient
Upper Extremities
1. Observe the patient for spontaneous/involuntary movement.
2. Apply painful stimuli to elicit a motor response (start with central pain; move to peripheral 
pain if no response occurs).
3. Assess for paralysis of the limb by lifting both arms and releasing them together. If one limb 
is paralysed it will fall more rapidly than the non paralysed arm.
Lower Extremities
1. Observe for spontaneous/involuntary movement.
2. Apply painful stimuli to elicit a motor response. Begin with central pain. Nailbed or 
peripheral pain can be attempted if the patient doesn’t respond to central pain (caution 
needs to be used when interpreting peripheral pain as it may stimulate spinal reflex 
responses vs withdrawal or other more deliberate responses).
3. To assess for paralysis of the one limb you can position the patient on their back and flex 
the knees so that both feet are flat on the bed. Release the knees simultaneously. If the leg 
falls to an extended position with the hip externally rotated, paralysis is present. The 
normal leg should stay in the flexed position for a few seconds and then gradually assume 
its previous position
SENSORY FUNCTION
When assessing sensory function remember that there are three main pathways for sensation and 
they should be compared bilaterally:
1. Pain and temperature sensation.
2. Position sense (proprioception).
3. Light touch.
Pain can be assessed using a sterile pin. Light touch can be assessed with a cotton wisp. To test 
proprioception, grasp the patient's index finger from the middle joint and move it side to side and 
up and down. Have the patient identify the direction of movement. Repeat this using the great toe.
Sensory Tests:
A number of tests for lesions of the sensory cortex can be done. Examples include the following:

Stereognosis: The ability to recognize an object by feel. Place a common object in the 
persons hand and ask them to identify the object.

Graphesthesis: “Draw” a number in the palm of the person’s hand and ask them to identify 
the number.

Two-Point Discrimination: Simultaneously apply two pin pricks to the skin surface. 
Continually repeat the test while bringing the two pins closer together, until the individual 
can no longer identify two separate stimuli. The finger tips are the most sensitive location for 
recognizing two point differences while the upper arms, thighs and back are the least 
sensitive.


Extinction: Touch the same spot on both sides of the body at the same time (eg, the left and 
right forearms. Ask the individual to describe how many spots are being touched. Normally, 
both sides are felt; with sensory lesions the individual will sense only one.

Point Locations: Touch the surface of the skin and remove the stimulus quickly. Ask the 
individual to touch the spot where the sensation was felt. Sensory lesions can impair accurate 
identification, even if they retain their sensation of light touch.
TONE and REFLEXES
Upper motor neuron problems (brain and spinal cord) are associated with increased tone. Lower 
motor neuron problems are associated with decreased tone. 
Look at the muscles on each side of the body in pairs. Assess for symmetry of bulk. 
Evaluation of the stretch reflexes assesses the intactness of the spinal reflex arc at various spinal 
cord levels. The limb should be relaxed while applying a short and snappy blow with a reflex 
hammer. Hold the hammer loosely in a relaxed manner, making a wrist action. Allow the hammer 
to bounce. 
Reflex responses: 
0
No response
1+
Diminished, low normal
2+
Average, normal
3+
Brisker than normal 
4+
Very brisk, hyperactive
Lower motor neuron disease is associated with 0 or 1+, upper motor neuron disease is associated 
with 3+ or 4+.
Biceps Reflex (C5 – C6)
Support the forearm on the examiners forearm. Place your thumb on the bicep tendon (located in 
the front of the bend of the elbow; midline to the anticubital fossa). Tap on your thumb to stimulate 
a response. 
Triceps Reflex (C7-C8)
Have the individual bend their elbow while pointing their arm downward at 90 degrees. Support 
the upper arm so that the arm hangs loosely and “goes dead”. Tap on the triceps tendon located 
just above the elbow bend (funny bone).
Brachioradialis Reflex (C5-C6):
Hold the person’s thumb so that the forearm relaxes. Strike the forearm about 2-3 cm above the 
radial styloid process (located along the thumb side of the wrist, about 2-3 cm above the round 
bone at the bend of the wrist). Normally, the forearm with flex and supinate. 
Quadriceps Reflex (Knee jerk) L2 – L4
Allow the lower legs to dangle freely. Place one hand on the quadriceps. Strike just below the knee
cap. The lower leg normally will extend and the quadriceps will contract.

If the patient is supine: Stand on one side of the bed. Place the examiners forearm under the thigh 
closest to the examiner, lifting the leg up. Reach under the thigh and place the hand on the thigh 
of the opposite leg, just above the knee cap. Tap the knee closest to the examiner, (the one that has 
been lifted up with the examiners forearm).
Achilles Reflex (ankle jerks) L5 – S2:
Flex the knee and externally rotate the hip. Dorsiflex the foot and strike the Achilles tendon of the 
heel. In conscious patients, kneeling on a chair can help to relax the foot.
Heel Lift
While the patient is supine, bend the knee and support the leg under the thigh. Have the leg “go 
dead”. Briskly jerk the leg to lift the heel of the bed. Normally, the leg will remain relaxed and the 
heel will slide upward; increased tone will cause the heel and leg to stiffen and lift off the bed. 
Babinski Response:
Dorsiflexion of the great toe with fanning of remaining toes is a positive Babinski response. This 
indicates upper motor neuron disease. It is normal in infants. 
CEREBELLAR FUNCTION
The cerebellum is responsible for muscle coordination and balance on the same side. To test 
cerebellar function use the following tests:
1. Finger to finger test: have the patient touch their index finger to your index finger (repeat 
several times).
2. Finger to nose test: perform with eyes open and then eyes closed.
3. Tandem walking: heel to toe on a straight line.
4. Romberg test: stand with feet together and arms at their sides. Have patient close his/her eyes 
and maintain this position for 10 seconds. If the patient begins to sway, have them open their 
eyes. If swaying continues, the test is “positive” or suggestive of cerebellum problems.
Dizziness that occurs in response to position changes is usually blood pressure initiated. If the 
patient sways during a Romberg test, but stops when the eyes are opened, the problem is probably 
visual or CN VIII (vestibular).

[collapse], syncope, incontinence)
2. Two or more of the following that occur rapidly after exposure to a likely allergen for that 
patient (minutes to several hours): 
a.
