PROTOCOL SYNOPSIS 
 
Protocol Title: 
A Phase 2, Open-Label, Multi-Dose, Dose Escalation Trial to 
Evaluate the Safety, Tolerability, Pharmacokinetics, and 
Pharmacodynamics of Intravenous Infusions of ALN-TTR02  
in Patients with TTR Amyloidosis 
Indication: 
Treatment of patients with transthyretin (TTR)-mediated 
amyloidosis (ATTR) 
Protocol Number: 
ALN-TTR02-002 
Phase of 
Development: 
2 
Design: 
Multi-center, multi-national, open-label, multi-dose, dose 
escalation study. 
Consented patients meeting the eligibility criteria will be 
enrolled into sequential cohorts of increasing doses of 
ALN-TTR02, the investigational drug.  Each cohort will 
comprise 3 patients, who are to receive 2 intravenous (IV) 
infusions of ALN-TTR02, 4 weeks apart. 
A Safety Review Committee (SRC) will evaluate safety in the 
study and determine if it remains acceptable to continue 
dosing per their safety review charter.  To ensure timely 
safety information exchange across the participating study 
centers, the SRC will be comprised of all Principal 
Investigators (PIs) participating in the study or their designee, 
the Alnylam Medical Monitor, and the Contract Research 
Organization (CRO) Medical Monitor. 
The dosing of cohorts will be as follows: 
• Dosing within a cohort: The first patient will receive 
their first dose and if the dose is well tolerated, per 
Section 5.7.3 (Dose-limiting Toxicity), Patients 2 and 
3 will receive their first dose at that same dose level no 
sooner than 48 hours apart, with Patient 2 receiving a 
dose of study drug no sooner than 48 hours after the 
dosing of Patient 1.  Similar to the first dose, the 
second dose will be administered to patients 4 weeks 
after the first dose in a sequential manner with at least 
48 hours separating dosing of each patient.   
• Dosing of the next cohort: Collective cohort safety and 
tolerability data on Patients 1 to 3 through at least 
8

96 hours post-first dose will be reviewed by the SRC; 
if the administered dose is found to be safe and well 
tolerated, dosing for the next cohort will begin no 
sooner than 96 hours after Patient 3 had safely 
received dose 1 from the previous cohort.  Patients in 
the cohort would be dosed and reviewed for safety and 
tolerability following the same procedures as used for 
other cohorts (as stated above).   
For patients on all dose levels other than the starting 
dose level of 10 µg/kg, prior to receiving the second 
dose, the SRC will review the cumulative safety and 
tolerability data of at least 2 patients from the previous 
dose level(s) with at least 96 hours of follow-up after 
receiving a second dose of study drug. 
The SRC will also be convened in the event of any potential 
dose-limiting toxicity (DLT) to determine whether stopping 
rules have been met. 
Study Sites 
This study is planned to be conducted at up to 10 study 
centers worldwide. 
Investigational Drug: 
ALN-TTR02 is comprised of drug substance ALN-18328 
(small interfering ribonucleic acid [siRNA] targeting wild 
type TTR messenger ribonucleic acid [mRNA] as well as all 
TTR mutations) formulated in a lipid nanoparticle (LNP) 
containing the following lipid excipients: DLin-MC3-DMA, 
PEG2000-C-DMG, DSPC, and cholesterol. 
Control Drug: 
Not applicable. 
Dosage, Route of 
Administration and 
Duration of 
Treatment of 
Investigational Drug: 
Four cohorts are planned to be enrolled to evaluate 
2 consecutive doses, 4 weeks apart of the following dose 
levels: 10, 50, 150, and 300 µg/kg ALN-TTR02.  Based on 
the interim evaluation of safety data, it may also be decided 
by the SRC that an optional cohort may be utilized which will 
include 3 additional patients.  Dosing in these optional cohorts 
may occur at a previously tested dose that was found to be 
safe and where stopping rules were not met or at an 
intermediate dose level.  Patients in the optional cohort would 
be dosed and reviewed for safety and tolerability following 
the same procedures as used for other cohorts.  Optional 
cohort(s) would be included to further confirm the safety 
and/or pharmacodynamic (PD) effect of previously evaluated 
dose levels, which may include evaluation of the original 
dosing regimen (once every 4 weeks), an alternative dosing 
regimen (once every 3 weeks), and/or an alternative

premedication regimen and infusion rate.  The dosing regimen 
for the first optional cohort will be once every 4 weeks, and 
the dosing regimen for the remaining 4 optional cohorts will 
be once every 3 or 4 weeks.  It is anticipated that the first 
2 optional cohorts will use the original premedication 
regimen, and the remaining 3 optional cohorts may be used to 
explore the alternative premedication regimen and infusion 
rate.   
The SRC will review all available safety data and make 
recommendations on dosing and premedication regimens 
prior to dosing of any of the optional cohorts.  
The Independent Ethics Committees (IECs) will be informed 
of the implementation of optional cohorts.  Up to 5 optional 
cohorts are permitted in this study. 
Patients receiving the original premedication regimen will be 
administered the following prior to each dose of ALN-
TTR02: 
• Oral (PO) dexamethasone (8 mg) or equivalent 
administered the evening before dosing and 20 mg 30 
to 60 minutes prior to start of infusion of ALN-
TTR02; 
• Oral paracetamol (500 mg) or equivalent the evening 
before dosing and 30 to 60 minutes prior to the start of 
infusion of ALN-TTR02; 
• Oral H2 blocker (e.g., ranitidine 150 mg or famotidine 
20 mg or equivalent other H2 blocker dose) the 
evening before dosing and 30 to 60 minutes prior to 
start of infusion of ALN-TTR02; and 
• Oral H1 blocker, 10 mg cetirizine or equivalent 
(hydroxyzine 25 mg or fexofenadine may be 
substituted if patient does not tolerate cetirizine) the 
evening before dosing and 30 to 60 minutes prior to 
start of infusion of ALN-TTR02. 
The alternative premedication regimen that can be used in 
select optional cohorts, as agreed upon by the SRC, will be 
administered prior to each dose of ALN-TTR02 and includes 
the following: 
• Intravenous (IV) dexamethasone (10 mg) or 
equivalent, administered at least 60 minutes prior to 
the start of infusion of ALN-TTR02;

• Oral paracetamol (500 mg) or equivalent at least 
60 minutes prior to the start of infusion of ALN-
TTR02; 
• Intravenous H2 blocker (e.g., ranitidine 50 mg, 
famotidine 20 mg, or equivalent other H2 blocker 
dose) at least 60 minutes prior to start of infusion of 
ALN-TTR02; and 
• Intravenous H1 blocker: diphenhydramine 50 mg IV 
(or equivalent other IV H1 blocker available at the 
study site) at least 60 minutes prior to start of infusion 
of ALN-TTR02.  Hydroxyzine or fexofenadine 25 mg 
PO or cetirizine 10 mg PO may be substituted for any 
patient who does not tolerate IV diphenhydramine or 
other IV H1 blocker. 
For patients receiving the original premedication regimen and 
infusion rate, doses of ALN-TTR02 will be administered IV 
over 60 minutes by a controlled infusion device at a flow rate 
of approximately 3.3 mL/min.   
For patients enrolled in the optional cohorts evaluating the 
alternative premedication regimen and infusion rate, the flow 
rate of ALN-TTR02 will be approximately 1.1 mL/min during 
the first 15 minutes (1/3rd the original flow rate) with the 
remainder of the infusion administered at a flow rate of 
3.3 mL/min for a total infusion time of approximately 
70 minutes. 
The infusion time may be extended up to 3 hours in the event 
of a mild or moderate infusion reaction (study drug 
administration will not be resumed for any patient following a 
severe infusion reaction).   
Patients will remain hospitalized at the study site for at least 
24 hours following completion of dosing on Days 0 and 28, 
for safety assessments and pharmacokinetic (PK) sampling.

Time on Study 
The duration of patient participation in this study is 
approximately 36 weeks (screening [up to 45 days prior to 
study drug administration] through Day 208). 
An open-label extension study at the recommended Phase 3 
dose and regimen (as derived from Study ALN-TTR02-002) 
is planned, which will enable the patients who enrolled in 
Study ALN-TTR02-002 to receive additional, long-term 
dosing and safety follow-up.  For some of the patients, this 
may preclude the completion of all of the follow-up period 
assessments of Study ALN-TTR02-002 if they are deemed 
eligible to participate in the extension study prior to 
completion of the full follow up through Day 208.  Such 
patients will be followed up for a minimum of 28 days after 
their last dose in the current ALN-TTR02-002 study prior to 
being enrolled in the extension study.  The extension study 
will be implemented only after dose escalation is completed in 
Study ALN-TTR02-002, with post second dose follow-up 
through Day 208 in at least 1 cohort at the highest dose. 
Note: A patient will be followed every 2 weeks after Day 56 
until TTR levels have recovered to at least 80% of baseline. 
Evaluations will be performed as indicated in the schedule of 
assessments. 
Primary Objective: 
• To evaluate the safety and tolerability of multiple doses of 
ALN-TTR02. 
Secondary 
Objectives: 
• To characterize the plasma and urine PK of ALN-TTR02. 
• To assess preliminary evidence of the PD effect of 
ALN-TTR02 on serum total TTR levels. 
Sample Size: 
Based on the entry criteria and the proposed dose escalation 
scheme, up to 27 patients are expected to be enrolled.  Three 
patients are to be enrolled at each dose level and up to 
5 optional cohorts of 3 patients each will be permitted. 
Inclusion and 
Exclusion Criteria:

Pharmacokinetic 
Assessments: 
The PK evaluation will include plasma-concentration time 
profiles for ALN-18328 and the novel lipid components 
DLin-MC3-DMA and polyethylene glycol (PEG)2000-C-
DMG.  ALN-18328 concentration will be determined at 
specified time points post-dose.  DLin-MC3-DMA and 
PEG2000-C-DMG concentrations will be determined at 
specified time points up to 180 days post- second dose.  An 
assessment of plasma concentrations of free and encapsulated 
siRNA will be determined at specified time points. 
If the infusion of study drug is stopped and the site is 
considering restarting, a PK blood sample will be taken when 
the infusion is stopped. 
Urine will be collected to determine ALN-18328 excreted in 
urine and renal clearance (CLR) of ALN-18328 after dosing 
with ALN-TTR02.  In addition urine samples will be 
collected to quantify analytes that may include DLin-MC3-
DMA and/or its metabolites at specified time points. 
Safety Assessments: 
26. Safety evaluations will include assessment of adverse 
events (AEs), electrocardiograms (ECGs), cardiac 
monitoring (telemetry), arterial oxygen saturation (SaO2) 
using pulse oximetry, vital signs (blood pressure, pulse 
rate, oral body temperature, and respiration rate), clinical 
laboratory safety tests (hematology, serum chemistry, 
liver function tests, thyroid function parameters, 
serology, coagulation parameters, urinalysis, cytokines, 
C-reactive protein, complement factors), and physical 
examinations. 
Other Assessments: 
27. Exploratory effects of ALN-TTR02 will be evaluated by: 
28. Serial measurement of circulating mutant and wild type 
TTR levels 
29. Serial measurement of circulating vitamin A and retinol 
binding protein (RBP) levels 
• Blood collections to explore the expression of hepatocyte 
derived proteins to further characterize the biological 
effects of siRNA LNPs.

Dose-Limiting 
Toxicities and 
Stopping Criteria: 
Dose-limiting toxicities will include any of the following: 
1. Any life-threatening toxicity. 
2. ALT and AST ≥5 × ULN or total bilirubin >2.0 mg/dL. 
3. An infusion reaction that requires hospitalization, despite 
premedication. 
4. Any other toxicity which in the opinion of the SRC 
precludes further dosing. 
Stopping Rules: 
For any DLT, accrual to that dose level will stop, all dosing 
will be discontinued, and dose escalation will end, pending 
further evaluation of all available safety data by the SRC. 
Statistical Methods: 
Statistical analyses will be primarily descriptive in nature.  
Adverse event summaries will include tabulations of all 
treatment-emergent AEs, treatment-related AEs, serious 
adverse events (SAEs), discontinuations due to AEs, and AEs 
of various grading severity.  By-patient listings will be 
provided for deaths, SAEs, and AEs leading to 
discontinuation of treatment. 
Descriptive statistics will be provided for clinical laboratory 
data, vital signs data, and ECG interval data, presented as both 
actual values and changes from baseline relative to each on-
study evaluation.  Laboratory shift tables from baseline to 
worst values will be presented. 
Pharmacokinetic analyses will be conducted using non-
compartmental and/or compartmental evaluation of ALN-
18328 (siRNA), DLin-MC3-DMA (lipid) and PEG2000-C-
DMG (lipid) plasma concentration-time data to determine PK 
parameter estimates using a validated software program, 
.  
PK and PD data will be assessed descriptively whenever 
possible and by exploratory statistical comparisons.

Note: The schedule of assessments for optional cohorts administered ALN-TTR02 once every 3 weeks is provided in Appendix 4. 
a 
Early termination procedures: if a patient withdraws prior to Day 56, then the Days 56 and 208 visits should be performed.  If a patient is withdrawn/withdraws after Day 56 
and prior to Day 208, then the Day 208 visit should be performed. 
b 
Interval medical history. 
c 
Focused physical examination (includes head/ears/eyes/nose/throat [HEENT], cardiovascular, respiratory, abdominal, and hepatic assessments).  If the screening physical 
examination was performed within 72 hours of Day 0, then the pre-dose (Day 0) physical examination does not need to be repeated; however, the patient’s weight will be 
obtained. 
d 
Weight measured on Day 0 and Day 28 will be used for calculating first and second dose, respectively. 
e 
Vital signs to include: blood pressure, pulse rate, oral body temperature, and respiratory rate.  Parameters are to be measured in the supine position using an automated 
instrument after the patient has rested comfortably for 10 minutes. 
f 
Serial measures (vital signs and pulse oximetry) are to be measured within 30 minutes pre-dose; at the end of infusion (EOI); and 30 (±5) minutes; 1, 2, and 3 (±15 minutes) 
hours; 6, 12, and 18 (±30 minutes) hours; and 24 (+30 minutes) hours post-infusion. 
g 
Not needed if a normal echocardiogram has been obtained within the past 90 days. 
h 
Serial electrocardiograms (ECGs) will be collected in 3 replicates within 30 minutes pre-dose, EOI, and 30 (±5) minutes, 2 and 4 (±15 minutes) hours, and 24 (+30 minutes) 
hours post-infusion. 
i 
Patients will be hospitalized at the study site for at least 24 hours after the end of infusion of study drug.  Patients may be discharged upon completion of review by the 
Investigator of ECG, sodium, potassium, creatinine, albumin, calcium, glucose, phosphate, and LFTs results obtained at 24-hours post-infusion, if results are deemed not 
clinically significant.  Any clinically significant findings must be discussed with the medical monitor to determine whether patient can be discharged and to formulate plans 
for patient follow-up. 
j 
Continuous cardiac monitoring will be performed via telemetry starting no later than 30 minutes prior to dosing and continuing through 24 hours (+1 hour) post-dose. 
k 
Day 0 pre-dose only, not performed on Day 28. 
l 
Serologies include hepatitis B surface antibody (HbsAb), hepatitis B surface antigen (HbsAg), and anti–hepatitis C virus antibody (anti-HCV Ab). 
m 
If the parameter was assessed and meets eligibility requirements within 72 hours of Days 0 and 28, then it does not need to be repeated pre-dose (Days 0 and 28, respectively). 
n 
Liver function tests include aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase, and bilirubin (total and direct). 
o 
Coagulation studies include prothrombin time (PT), activated partial thromboplastin time (aPTT), and international normalized ratio (INR). 
p 
Lipid panel (non-fasting) includes total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL), and triglycerides 
will be collected on Day 0 only. 
q 
Pre-dose samples for TTR protein, vitamin A, and RBP measurements will be drawn immediately (within 10 minutes) prior to the premedications and immediately prior to 
dosing. 
r 
A patient will be followed approximately every 2 weeks after Day 56 if their TTR level continues to recover but is not found to have returned to within at least 80% of the 
baseline value.  If this occurs, the patient will be followed and discussed at each SRC meeting until the TTR level returns to within at least 80% of the baseline value. 
s 
Thyroid function tests include thyroid stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3). 
t 
A blood sample will be collected for the assessment of complement Bb immediately (within 10 minutes) pre-dose, and 30 (±5) minutes, and 2 (± 15 minutes) and 24 hours 
(±120 minutes) post infusion.  If the patient experiences an infusion reaction, a blood sample for analysis of complement factors should be obtained within 1 hour of the start 
of the reaction.

u 
A blood sample for the assessment of tryptase and C3a is to be collected only in the event of an acute infusion reaction: at time of event or as soon as possible after onset, 
1 hour, and 24 hours after the event. 
v 
Premedications include dexamethasone (8 mg, or equivalent), paracetamol (500 mg, or equivalent), H2 blocker (e.g., 150 mg ranitidine or 20 mg famotidine, or equivalent 
other H2 blocker dose), and H1 blocker (10 mg cetirizine, 25 mg hydroxyzine, fexofenadine or equivalent may be substituted) will be self-administered per os (PO) the 
evening before study drug administration.  Thirty to 60 minutes prior to the start of study drug infusion, dexamethasone (20 mg PO, or equivalent), paracetamol (500 mg PO, 
or equivalent), an H2 blocker (PO), and an H1 blocker (PO) will be administered by study site personnel.  Patients enrolled in an optional cohort evaluating the use of an 
alternative premedication regimen, as agreed upon by the SRC, will receive the following medications at least 60 minutes prior to the start of infusion of ALN-TTR02:  
dexamethasone (10 mg IV, or equivalent), paracetamol (PO 500 mg; or equivalent), IV H2 blocker (e.g. ranitidine 50 mg, famotidine 20 mg, or equivalent other H2 blocker 
dose), and IV H1 blocker (e.g., diphenhydramine 50 mg or equivalent; hydroxyzine or fexofenadine 25 mg PO or cetirizine 10 mg PO may be substituted for any patient who 
does not tolerate IV diphenhydramine or other IV H1 blockers).  These patients will not receive any premedications the evening prior to ALN-TTR02 dosing. 
w 
Site personnel are to call patients the day before dosing to remind them to take premedications that evening (the day before dosing).  This reminder will not be needed for 
patients enrolled in optional cohorts evaluating the alternative premedication regimen. 
x 
The infusion site will be assessed for any localized reaction pre-dose, during infusion, and for 30 minutes after the infusion. 
y 
A blood sample for the assessment of cytokines and C-reactive protein (CRP) will be collected immediately (within 10 minutes) pre-dose, and 2 (±15 minutes), 6 (±15 
minutes), and 24 hours (±120 minutes) post infusion.  If the patient experiences an infusion reaction, a blood sample for analysis of cytokines should be obtained within 
1 hour of the start of the reaction. 
z 
For each dose, plasma PK samples (siRNA and lipids) will be collected pre-dose (within 1 hour of planned dosing start), EOI, and then 5, 10, and 30 minutes, and 1, 2, 4, 6, 
24 and 48 hours post infusion.  Samples will also be collected on Days 7, 14, 21, 35, 42, 49, 56, 112, and 208.  Plasma PK on Day 0 at EOI and then 2 hours post-infusion will 
be analyzed for both free and encapsulated siRNA for cohort 3 and onward, including any optional cohorts.  For each post dose PK blood draw, the following sampling 
windows are allowed: ±1 minute for the 5- and 10-minute draws; ±2 minutes for the 30-minute draws; ±5 minutes for the 1-, 2-, 4-, and 6-hour draws; and ±120 minutes for 
the 24- and 48-hour draws. 
aa 
For each dose, urine PK samples will be collected pre-dose (within 1 hour of planned dosing start), and from 0-6 hours post-infusion (pooled). Samples will also be collected 
on Days 7, 14, 21, 35, 42, 49, 56, 112, and 208.   
bb Pre-dose samples should be collected prior to infusion, but after premedications have been administered.

INTRODUCTION 
1.1 
Background and Rationale 
1.1.1 
Transthyretin Biology and Impact of Transthyretin Lowering 
Transthyretin (TTR), also known as prealbumin, is a tetramer protein produced 
predominantly by hepatocytes (>95% of TTR is liver-derived), with a small fraction 
produced in the choroid plexus and retina.1
In humans, approximately 15% of T4 circulating in the plasma is bound to TTR; the 
remainder is predominantly bound to thyroxine-binding globulin (TBG).  In the mouse, 
where TTR plays a greater role as a carrier for T4, the absence of TTR reduces 
circulating levels of T4 but does not adversely affect the concentration of the hormone in 
peripheral tissues.2,3   
  The primary physiological role of TTR is to 
serve as a carrier of retinol (also known as vitamin A); it also plays a minor role as a 
carrier for thyroxine (T4).   
Vitamin A circulates through the plasma primarily bound to retinol binding protein 
(RBP).1  The clearance of RBP from the circulation is greatly reduced through its binding 
to TTR.  Because vitamin A is lipid-soluble, it can diffuse across the membranes of cells 
and thus, most tissues receive adequate levels of vitamin A obtained normally from the 
diet without its being bound to RBP.  Studies performed in TTR-knockout mice have 
demonstrated that in the absence of TTR, circulating levels of both RBP and vitamin A 
are dramatically reduced (e.g., 5% of vitamin A seen in wild type [WT] mice); however, 
the concentration of vitamin A in the tissues is comparable with that seen in WT mice.4,5  
In addition, the TTR-knockout mice did not demonstrate any signs of vitamin A 
deficiency.  In humans, individuals with mutations in the RBP gene leading to complete 
loss of circulating RBP and very low concentrations of circulating vitamin A have not 
shown any significant signs of vitamin A deficiency other than modest retinal dystrophy 
and decrease in night vision.6  This confirmed the finding in mice that vitamin A uptake 
by most tissues continues in the absence of RBP.  In women with breast cancer treated 
for an average of at least 30 months with the retinoid fenretinide, which causes a 75% 
reduction in circulating vitamin A levels, there were no reports of night blindness or any 
other signs of vitamin A deficiency, and only subtle changes in retinal function were seen 
on electroretinograms in women older than 50 years of age who were on fenretinide for 
30 months or longer.7,8  The safety of lowering vitamin A through TTR suppression has 
now been further confirmed by the absence of AEs in TTR amyloidosis patients treated

with ALN-TTR01 who experienced substantial lowering of both TTR and vitamin A (see 
Section 1.3). 
1.1.2 
Disease Overview 
Mutations in the TTR gene can lead to destabilization of the tetrameric protein and 
disassociation of the TTR subunits into dimers and individual monomers.  These 
misfolded TTR monomers (both mutant and WT) can then self-assemble into amyloid 
fibrils.9  The amyloid fibrils are deposited into the extracellular space of various tissues 
where they form amyloid plaques, with the peripheral nervous system, gastrointestinal 
tract, and heart being major sites of deposition. 
There are over 100 reported TTR genetic mutations.  These mutations are phenotypically 
expressed as a spectrum of disease which is collectively referred to as TTR-mediated 
amyloidosis (ATTR).10  There is a range of clinical manifestations of ATTR; the most 
common manifestations include some form of cardiac and/or neurologic involvement 
(e.g., cardiomyopathy, autonomic neuropathy, and sensory and motor neuropathy) that 
depends, in part, upon the particular TTR mutation and the site of amyloid deposition.  
Transthyretin amyloidosis is associated with severe morbidity and mortality, with a life 
expectancy limited to approximately 5 to 15 years from symptom onset.11 
Two significant clinical syndromes of ATTR have been described: familial amyloidotic 
polyneuropathy (FAP) and familial amyloidotic cardiomyopathy (FAC), both of which 
are characterized by amyloid deposits of both mutant and WT TTR.12   
Familial amyloidotic polyneuropathy, caused predominantly by the V30M mutation, 
occurs primarily in families with heritage from Portugal, Sweden and Japan, has an 
earlier onset (age 30-50 years), and is characterized initially by peripheral neuropathy 
leading to sensory and motor deficits as well as profound autonomic dysfunction that 
produces disabling gastrointestinal pathology, orthostatic hypotension, and bladder 
dysfunction.13,14  Amyloid infiltration of the sinus node and atrioventricular conduction 
system in the heart is also common in FAP.  Sudden death is not uncommon in FAP, and 
is believed to result from heart block or tachyarrhythmias.15,16   
Familial amyloidotic cardiomyopathy, caused primarily by the TTR variant V122I, is a 
late-onset (age >60 years) syndrome in which amyloid deposition is largely restricted to 
the heart and manifests as conduction defects, arrhythmias, congestive heart failure, and 
death; neuropathy is uncommon.17  The V122I mutation is found in up to 4% of African 
27

Americans and in over 5% of West African populations, although rates of disease 
penetrance are low.18   
It is estimated that 45,000 – 50,000 individuals have FAP or FAC.  In both FAP and 
FAC, quality of life is severely impacted following the onset of symptoms, and the 
disease proceeds inexorably to death.19,20 
Because the liver is the primary source of mutant TTR, liver transplantation has been 
used over the past 20 years in an attempt to treat ATTR.1  However, the procedure is only 
effective in halting or slowing the progression of disease in patients with an early age of 
onset,21 especially for those with the V30M mutation and short disease duration prior to 
transplant; consequently almost two-thirds of ATTR patients are not transplant-eligible.  
When performed early in the course of the disease, liver transplantation can stabilize and 
slow progression of neuropathy in patients with FAP due to V30M.  However, in FAC 
patients and FAP patients with evidence of cardiac involvement, liver transplantation is 
contraindicated since it does not halt the progression of cardiac disease in these 
patients,22,23,24,25 and may actually accelerate the course of cardiomyopathy due to further 
deposition of WT TTR (originating from the transplanted liver) in the heart.26 
Tafamidis, a TTR tetramer stabilizer, was approved (November 2011) in the European 
Union (EU) for the treatment of ATTR in adult patients with stage 1 symptomatic 
polyneuropathy to delay peripheral neurologic impairment.27  However, the large 
majority of ATTR patients do not qualify for either liver transplantation or tafamidis.  In 
these patients, the disease is primarily managed with palliative care.   
1.1.3 
RNA interference 
Ribonucleic interference (RNAi) is a naturally occurring cellular mechanism for 
regulating gene expression that is mediated by “small interfering ribonucleic acids” 
(siRNAs).28  Typically, synthetic siRNAs are 19 to 23 base pair double-stranded 
oligonucleotides in a staggered duplex with a 2-nucleotide overhang at one or both of the 
3' ends.  Such siRNAs can be designed to target an endogenous or virally-expressed gene.  
When introduced into cells, the net effect of an RNAi-based pharmacological approach is 
the binding of the siRNA to its complementary messenger ribonucleic acid (mRNA) 
sequence, cleavage of this target mRNA, and suppression of the target protein.29  The 
ability to selectively and potently degrade the mRNA encoding the TTR protein using an 
siRNA offers a potent and specific approach for the treatment of ATTR.

Unformulated siRNAs, and those without chemical modification, are rapidly degraded 
and eliminated upon systemic administration, and thus do not achieve significant tissue 
distribution.30  As a result, various formulations are used to target siRNA distribution to 
tissues, and to facilitate their uptake into the relevant cell type.  One approach that has 
been used successfully in vivo, including in rodents and non-human primates (NHPs), 
employs intravenous (IV) delivery of siRNAs in lipid nanoparticles (LNPs).,31,32,33,34  
These LNPs, with their small size (<100 nm) and low surface charge, can pass through 
the fenestrated vascular endothelium of the liver.  Endocytosis of the intact LNPs, 
followed by fusion with the endosomal membrane and release of the siRNA into the 
cytoplasm, results in the siRNA engaging the endogenous RNAi machinery described 
above to cause targeted degradation of the mRNA, and a consequent reduction in target 
protein levels. 35,36 
1.1.4 
ALN-TTR02 
Alnylam Pharmaceuticals is developing ALN-TTR02 Solution for Injection (hereafter 
referred to as ALN-TTR02), a synthetic investigational RNAi therapeutic comprising an 
siRNA (ALN-18328) targeting the TTR mRNA. 
Unformulated synthetic siRNAs administered by IV injection are rapidly eliminated and, 
thus, do not achieve significant tissue distribution.37  Since 95% of TTR is produced in 
the liver, it was necessary to develop a formulation that could deliver ALN-18328 to the 
liver.  One approach that has been used successfully employs IV delivery of siRNA in 
liposomal formulations.  Recent preclinical studies have demonstrated targeted organ 
distribution, leading to significantly improved efficacy with lipid particle formulated 
siRNAs directed against liver-expressed genes.38,39  Following IV administration, the 
lipid particles enter the circulation and extravasate into the interstitial fluid.  The lipid 
particles accumulate preferentially in the liver due to their ability to pass through the 
fenestrated capillaries in that organ.  Subsequent uptake of the lipid particles is believed 
to result from endocytosis of the intact particles, followed by fusion with the endosomal 
membrane,40 leading to release of the siRNA into the cytoplasm.  The siRNA is then 
available to interact with the endogenous cellular RNAi machinery to bring about 
targeted degradation of the mRNA and subsequent reductions in the target protein levels.   
ALN-TTR02 consists of ALN-18328, an siRNA designed to suppress production of both 
mutant and WT TTR, formulated in an LNP termed AF-011.  The LNP enables delivery 
of the siRNA primarily to the liver upon systemic administration, resulting in the down-

regulation of hepatic TTR expression, and in turn, reducing serum mutant and WT TTR 
levels.  The proposed indication for ALN-TTR02 is for the treatment of ATTR.  
ALN-TTR02 is intended for administration as an IV infusion over 1 hour.   
ALN-TTR02, a second generation siRNA LNP formulation termed AF-011, employs the 
same siRNA (ALN-18328) as ALN-TTR01, which utilizes the first generation LNP 
(termed stable nucleic acid lipid particles [SNALP]).  Both ALN-TTR01 and 
ALN-TTR02 are intended for the treatment of patients with ATTR; the AF-011 
formulation, however, has been optimized to be more potent such that mRNA and protein 
reduction effects are observed at significantly lower doses with AF-011 than with the 
SNALP formulation.  Furthermore, ALN-PCS02 employs the same AF-011 formulation 
as ALN-TTR02, but has a siRNA targeting a different liver derived protein, that of 
PCSK9.  Since the overall nonclinical toxicology findings are attributable primarily to the 
lipid formulation regardless of the encapsulated siRNA, previous non-clinical evaluation 
(including pharmacology, pharmacokinetics [PK], metabolism, and safety/toxicity), and 
clinical evaluations of ALN-PCS02 and ALN-TTR01 can provide important data 
regarding the anticipated safety of ALN-TTR02 (see Section 1.3).

Summary of Clinical Data with siRNA-LNPs 
Clinical trials with multiple different RNAi medicinal products using local or systemic 
administration in indications including age-related macular degeneration, respiratory 
syncytial virus (RSV) infection, oncology, and renal failure have been conducted.28  
Alnylam currently has experience with 4 systemic delivery programs in the clinic 
evaluating the safety and efficacy of different siRNAs in 2 different LNP formulations, 
including 1 program which employs the same AF-011 formulation as ALN-TTR02.  An 
overview of the safety and pharmacological clinical data with these siRNA-LNPs is 
included in the ALN-TTR02 Investigator’s Brochure (IB), Edition 3, dated 
19 October 2012.  
 
 
 
   
Importantly, a Phase 1 study with ALN-TTR02 was recently completed.  Study ALN-
TTR02-001 was a multicenter, randomized, placebo-controlled, single-blind, single-
ascending dose clinical study conducted in the UK to evaluate the safety, tolerability, PK, 
and pharmacodynamic (PD) in healthy volunteers (EudraCT # 2011 005291-42).  ALN-
TTR02 was administered as a single 60-minute IV infusion to healthy volunteers at the 
following doses: 10, 50, 150, 300, and 500 µg/kg (4 patients per dose level; 3 receiving 
ALN-TTR02 and 1 receiving placebo).  Patients were premedicated with dexamethasone,

H1 and H2 blockers, and paracetamol prior to dosing to minimize the risk of infusion 
reaction.  The data show that ALN-TTR02 was safe and well-tolerated and exhibited 
robust effects on serum TTR levels at doses ≥0.15 mg/kg.  Lowering of TTR levels was 
reversible following administration of a single dose, and there were no AEs associated 
with lowering TTR by >90%.  Further details on this study can be found in the ALN-
TTR02 IB, Edition 3. 
1.4 
Study Hypothesis and Rationale 
ALN-TTR02 is a novel drug to treat ATTR and consists of a single LNP-formulated 
siRNA (ALN-18328) targeting both WT and all known mutant forms of TTR.  Since 
TTR amyloid deposits consist of both mutant and WT TTR, it is desirable to be able to 
lower the production of both WT and mutant TTR with a single drug in order to treat the 
different variants of ATTR.  While liver transplantation has shown both the advantages as 
well as the limitations of eliminating mutant TTR in FAP, it also underscores the 
potential advantage of a drug that can lower both mutant and WT TTR for treating both 
the cardiac and neuropathic complications of ATTR.   
The ALN-TTR02 nonclinical pharmacology data described in Section 1.2 demonstrate 
that administration of ALN-TTR02 results in significant suppression of mutant and WT 
TTR mRNA as well as protein, and that this suppression has the potential to prevent the 
deposition of TTR in key tissues.  It is anticipated that lowering of mutant and WT TTR 
protein in humans will result in a decrease in the deposition of amyloid fibrils, thereby 
potentially slowing down or reversing the course of the disease. 
The primary objective of this study is to evaluate the safety and tolerability of a multiple 
doses of ALN-TTR02 administered to patients with ATTR.  Secondary objectives include 
the characterization of plasma and urine PK for ALN-TTR02 as well as to assess 
preliminary evidence of the PD effect of ALN-TTR02 on serum total TTR. 
1.5 
Dose Selection and Rationale 
Two consecutive ALN-TTR02 doses, separated by a 4-week period (or a 3-week period 
in select optional cohorts), will be administered to patients.  Study drug will be 
administered as a 60-minute IV infusion with the following proposed doses for each of 
the original cohorts:  10, 50, 150, and 300 μg/kg ALN-TTR02.  For those patients 
enrolled in an optional cohort evaluating the alternative premedication regimen and 
infusion rate, the study drug will be administered IV over approximately 70 minutes.

Based on the preclinical and clinical experience with siRNA-LNPs to date, it appears that 
the translation of data from animals to humans occurs based on a mg/kg basis.  However, 
taking a more conservative approach, exposures based on allometric scaling as well as 
body surface area have been estimated, and safety margins were calculated (see 
Investigator’s Brochure).  Based on allometric scaling, a 2-fold and 44-fold safety margin 
was determined for the starting dose in humans (10 μg/kg)
 
 a similar margin was obtained based on body surface area.  Based 
on body weight, the margin for the proposed human starting dose is 10-fold and 100-fold 
.  The top dose proposed in the study (300 μg/kg) is 
.  Preliminary safety data 
are available from ongoing Phase 1 trials with ALN-TTR02 and ALN-PCS02.  In the 
ALN-TTR02-001 Phase 1 trial in healthy volunteers, these same dose levels were found 
to be safe and well-tolerated.  Furthermore, ALN-PCS02, which uses the same second 
generation LNP formulation as ALN-TTR02, was safe and well-tolerated at doses up to 
400 µg/kg in healthy volunteers with elevated cholesterol.  See the ALN-TTR02 
Investigators Brochure and its Expedited Safety Report addendum dated 7 June 2012 for 
updated information on the ALN-TTR02 and ALN-PCS02 Phase 1 trials. 
Additionally, a conservative dosing approach is being taken.  In each cohort, patients will 
be dosed in a sequential fashion with a minimum of 48 hours elapsing between patients.  
Collective cohort safety and tolerability data on the 3 patients from the prior cohort 
through at least 96 hours post-dose will be reviewed by the Safety Review Committee 
(SRC) prior to approving dosing for the next dose level.  In addition, cumulative safety 
and tolerability data observed in at least 2 patients through at least 96 hours post-second 
dose of the previous cohort will be reviewed by the SRC prior to administration of the 
second dose of study drug.   
Based on the interim evaluation of safety data, it may also be decided by the SRC that an 
optional cohort may be utilized which will include 3 additional patients.  Dosing in these 
cohorts may occur at a previously tested dose that was found to be safe and where 
stopping rules were not met or at an intermediate dose level.  Patients in the optional 
cohort would be dosed and reviewed for safety and tolerability following the same 
procedures as used for other cohorts.  The optional cohort(s) would be included to further 
confirm the safety and/or PD effect of previously evaluated dose levels, which may 
include evaluation of the original dosing regimen (once every 4 weeks), an alternative 
dosing regimen (once every 3 weeks), and/or an alternative premedication regimen and

infusion rate.  The dosing regimen for the first optional cohort will be once every 
4 weeks, and the dosing regimen for the remaining 4 optional cohorts will be once every 
3 or 4 weeks.  It is anticipated that the first 2 optional cohorts will use the original 
premedication regimen, and the remaining 3 optional cohorts may be used to explore the 
alternative premedication regimen and infusion rate.  The SRC will review all available 
safety data and make recommendations on dosing and premedication regimens prior to 
dosing of any of the optional cohorts.  If this occurs, the Independent Ethics Committees 
(IECs) will be informed of the implementation of optional cohorts.  Up to 5 optional 
cohorts of 3 patients each are permitted in this study. 
The optional cohorts will follow the same treatment schema as cohorts 1 to 4, as outlined 
in Section 5.6. 
1.6 
Risk-Benefit Assessment 
No benefit is expected from the transient lowering of TTR during this study.  Please see 
Investigator’s Brochure for expanded risk/benefit assessment. 
1.6.1 
Infusion-Related Reactions 
Infusion-related reactions can occur with systemic administration of certain biological 
agents such as liposomes or monoclonal antibodies.  These may include acute reactions 
or delayed febrile reactions.  Premedicating patients with corticosteroids and/or 
antihistamines, or slowing of the infusion rate, are approaches that have been taken to 
reduce the incidence and/or severity of IRRs.41,42  Consistent with this, a premedication 
regimen (dexamethasone or equivalent, paracetamol or equivalent, histamine H1/H2 
receptor antagonist [H1/H2 blocker]) similar to that proposed for this study was used in 
the prior ALN-PCS02 and ALN-TTR01 clinical studies that employed siRNAs in LNP 
formulations (Section 1.3). 
In order to reduce the potential for an IRR with ALN-TTR02, all patients in this study 
will be premedicated prior to dosing with ALN-TTR02.  The premedication regimen will 
include dexamethasone (or equivalent), paracetamol (or equivalent), and H1 and H2 
blockers (as described in Section 5.5).  The infusion rate of 1 hour or longer will also 
help to reduce the potential for acute IRRs.  The suggested clinical course for managing 
IRRs is provided in Section 5.11 and in Appendix 1 and Appendix 2.

1.6.2 
Hepatotoxicity 
Alnylam’s previous clinical experience with LNPs, either second generation AF-011 or 
first generation SNALP, in Phase 1 studies suggests that the risk for hepatotoxicity is 
low.  No clinically significant changes in LFTs have been seen to date in the ongoing 
ALN-VSP02, ALN-TTR01, or ALN-PCS02 Phase 1 trials.  In the ALN-TTR02 study, 
the risk of liver toxicity is lowered by requiring patients to have adequate liver function, 
which will then be followed closely through serial measurements after dosing.

STUDY PLAN 
3.1 
Overall Design 
Protocol ALN-TTR02-002 is a multi-national, multi-center, Phase 2, open-label, multi-
dose, dose escalation study designed to determine the safety, tolerability, PK, and PD of 
2 consecutive doses (separated by approximately 4 weeks) of ALN-TTR02 in patients 
with ATTR. 
Patients of any mutant TTR genotype with a biopsy-proven diagnosis of ATTR who 
exhibit documented signs/symptoms of the disease (e.g., sensory, motor, or autonomic 
neuropathy) that are at least mild to moderate in severity will be eligible for the study, 
provided they have a body mass index (BMI) of 17-33 kg/m2, an adequate performance 
status (Karnofsky performance status of 60% or greater; see Appendix 3), adequate 
hepatic and renal function, no active infection or inflammatory disorder, stable cardiac 
status, and have not had a liver transplant.   
Two doses, separated by 4 weeks, of ALN-TTR02 (10, 50, 150, and 300 μg/kg) will be 
investigated in 4 sequential cohorts comprised of 3 patients each.  No patients will be a 
member of more than 1 treatment group.  An alternative dosing regimen of 2 doses of 
ALN-TTR02 (at a dose previously determined by the SRC to be safe and tolerable) 
separated by 3 weeks may be evaluated in the optional cohort(s).  
Within each of the cohorts, the first patient will receive their first dose and if the dose is 
well tolerated (per Section 5.7.3, Dose-limiting Toxicity), Patients 2 and 3 will receive 
their first dose at that same dose level no sooner than 48 hours apart, with Patient 2 
receiving a dose of study drug no sooner than 48 hours after the dosing of Patient 1.  
Similar to the first dose, the second dose will be administered to patients 4 weeks after 
the first dose in a sequential manner with at least 48 hours separating dosing of each 
patient.  If after the first dose, ALT and AST are > 2.5 x ULN, that patient would not 
receive their second dose.    
Dose escalation to the next cohort will proceed after the collective safety and tolerability 
data through at least 96 hours post-first dose from the 3 patients in the previous cohort 
has been reviewed by the SRC.  If the administered dose is found to be safe and well 
tolerated, dosing for the next cohort will begin no sooner than 96 hours after Patient 3 has 
safely received dose 1 from the previous cohort.  Patients in the cohort would be dosed

and reviewed for safety and tolerability following the same procedures as used for other 
cohorts (as stated above).   
For patients on all dose levels other than the starting dose level of 10 µg/kg, prior to 
receiving the second dose the SRC will review the cumulative safety and tolerability data 
of at least 2 patients from the previous dose level(s) with at least 96 hours of follow-up 
after receiving a second dose of study drug. 
For any DLT, accrual to that dose level will stop, all dosing will be discontinued, and 
dose escalation will end, pending further evaluation of all available safety data by the 
SRC (see Section 5.7.4).  The SRC may be convened earlier at the discretion of Alnylam 
if important safety issues arise requiring the attention of the committee (e.g., new safety 
information attained in other ongoing studies with ALN-TTR02). 
The duration of patient participation in this study is approximately 36 weeks.  Patients 
will be screened from -45 to -3 days prior to dose administration.  Eligible patients will 
undergo further pre-treatment assessments (performed on Day 0).  Patients receiving the 
original premedication regimen will receive oral premedication with dexamethasone (or 
equivalent), paracetamol (or equivalent), and H1 and H2 blockers the night before and 30 
to 60 minutes prior to each dose of ALN-TTR02 to reduce the potential of an IRR (see 
Section 5.5).  Those patients in an optional cohort evaluating the alternative 
premedication regimen, as agreed upon by the SRC, will receive IV dexamethasone (or 
equivalent), oral paracetamol (or equivalent), and IV H1 and H2 blockers at least 60 
minutes prior to ALN-TTR02 dosing; no premedication will be administered the evening 
prior to dosing.  On Days 0 and 28, patients will receive a single dose of ALN-TTR02 
administered as a 60-minute IV infusion (for cohorts with the original premedication 
regimen and infusion rate), or as an approximate 70-minute IV infusion, for those 
patients in an optional cohort evaluating the alternative premedication regimen and 
infusion rate.  The infusion time may be extended up to 3 hours in the event of a mild or 
moderate infusion reaction (study drug administration will not be resumed for any patient 
following a severe infusion reaction).  Details on the study drug administration are 
provided in Section 5.6.  Patients will be hospitalized at the study site for at least 
24 hours after the end of the study drug infusion. Patients may be discharged upon 
Investigator review of the 24 hour ECG, LFTs, and a subset of serum chemistries 
(sodium, potassium, creatinine, albumin, calcium, glucose, and phosphate), if results are

deemed not clinically significant.  Patients will return to the site for out-patient visits for 
safety, PK, and PD monitoring up to 208 days post-dose (see Section 6 for details).   
The SRC will evaluate safety in the study and determine if it remains acceptable to dose 
escalate or administer the second dose to the next dose level per their safety review 
charter.  To ensure timely safety information exchange across the participating study 
centers, the SRC will be comprised of all Principal Investigators (PIs) participating in the 
study or their designee, the Alnylam Medical Monitor, and the Contract Research 
Organization (CRO) Medical Monitor.  The SRC will communicate frequently to ensure 
that patients are dosed according to the time intervals specified in Section 5.6, even as 
patients are being accrued across multiple centers. 
3.2 
Safety Assessments 
Safety monitoring will include assessment of AEs, 12-lead ECGs, cardiac monitoring 
(telemetry), arterial oxygen saturation (SaO2) using pulse oximetry, vital signs (blood 
pressure, pulse rate, oral body temperature, and respiratory rate), clinical laboratory 
safety tests (hematology, serum chemistry, LFTs, thyroid function parameters, serology, 
coagulation parameters, urinalysis, cytokines, CRP, and complement factors), and 
physical examinations.  Patients will be closely monitored for both acute and delayed 
IRRs (see Section 5.11 for clinical guidance).  All IRRs will be recorded as AEs. 
3.3 
Pharmacodynamic Assessments 
The PD of ALN-TTR02 in patients with ATTR will be evaluated by serial measurement 
of serum concentrations of serum total TTR levels. 
3.4 
Pharmacokinetic Assessments 
The PK evaluation will include plasma-concentration time profiles for siRNA 
ALN-18328 and the novel lipid components DLin-MC3-DMA and PEG2000-C-DMG.  
ALN-18328 concentration will be determined at specified time points post-dose.  An 
assessment of plasma concentrations of free and encapsulated siRNA will be determined 
at specified time points.  PEG2000-C-DMG and DLin-MC3-DMA will be determined at 
specified time points up to 180 days post-dose.  Renal clearance (CLR) will be 
determined for ALN-18328 and DLin-MC3-DMA and/or its metabolites excreted in the 
urine.

Assignment to Dose Cohort/Patient Number 
4.4.1 
Assignment to Dose Cohort 
After confirmation of eligibility during screening, patients satisfying the entry criteria 
will be assigned to the cohort currently enrolling.  Each cohort will comprise 3 patients.  
No patients will be a member of more than 1 treatment group. 
A unique patient identification number will be assigned sequentially after the patient has 
completed all of the screening procedures and is determined to be eligible for the study.  
If applicable, replacement patients will receive the same treatment allocation as those 
whom they replace. 
4.4.2 
Blinding Procedures 
Not applicable. 
4.5 
Early Patient Withdrawal 
Patients are free to withdraw from the study at any time and for any reason, without 
penalty to their continuing medical care.  A patient will be considered to have completed 
the study if the patient receives both doses of study medication and completes protocol-
specified procedures up through Day 56.   
4.5.1 
Reasons for Withdrawal 
The Investigator may withdraw a patient from the study if the patient: 
• 
Is in violation of the protocol. 
• 
Experiences a serious or intolerable AE (including infusion reactions). 
• 
Experiences a DLT (see Section 5.7.3). 
• 
Develops conditions listed in the exclusion criteria during the course of the study. 
• 
Becomes pregnant. 
• 
Requires a prohibited medication (see Section 5.10). 
• 
Requests to be withdrawn from the study. 
The Investigator will also withdraw the patient from the study upon the request of 
Alnylam or the SRC, or if Alnylam terminates the study.  Upon occurrence of a serious or 
intolerable AE, the Investigator will confer with Alnylam before discontinuing the 
patient, and the SRC will be notified.  A patient may withdraw consent to participate in 
the study at any time.

4.5.2 
Handling of Withdrawals 
Patients are free to withdraw from the study upon request.  Patient participation in the 
clinical study may be terminated at any time at the discretion of the Investigator or 
Alnylam. 
In the event a patient is withdrawn from the study, the CRO Medical Monitor must be 
informed immediately.  If there is a medical reason for withdrawal, the patient will 
remain under the supervision of the Investigator for protocol-specified safety follow up 
procedures.  The SRC may be notified. 
Patients who voluntarily withdraw are termed dropouts.  Dropouts may be replaced 
following discussion with the Investigator and Alnylam (see Section 4.5.3).   
Patients who are withdrawn due to AEs during infusion of the ALN-TTR02 will not be 
replaced. 
If a patient is withdrawn/withdraws the discharge procedures should be performed and an 
early termination (ET) visit scheduled as follows: 
• 
If a patient is withdrawn/withdraws prior to Day 56 then the Day 56 assessments 
should be completed; 
• 
If a patient is withdrawn/withdraws after Day 56 and prior to Day 208 then the 
Day 208 assessments should be completed. 
If a patient is withdrawn due to an AE, appropriate medical care should be provided and 
the AE should be followed through 56 days post last dose.  Follow-up procedures should 
be conducted as scheduled. 
Patients who fail to return for final evaluations will be contacted by the site in an attempt 
to have them comply with the protocol.  The site will follow up by telephone at least 
twice and send a registered letter to any patient who fails to return for the final 
evaluation. 
When a patient withdraws from the study, the primary reason for discontinuation must be 
recorded in the appropriate section of the case report form (CRF) and all efforts will be 
made to complete and report the observations as thoroughly as possible.   
4.5.3 
Patient Replacement 
Any patient who misses a dose, does not receive 80% of each ALN-TTR02 dose, or who 
discontinues from the study for a non-safety related issue, as determined by the SRC,

STUDY MEDICATION 
5.1 
Presentation of Study Drug 
ALN-TTR02 Solution for Injection is an RNAi therapeutic consisting of drug substance 
ALN-18328 (siRNA targeting TTR mRNA) formulated in LNPs.  The ALN-TTR02 drug 
product is a sterile formulation of ALN-18328 with lipid excipients (DLin-MC3-DMA, 
DSPC, cholesterol and PEG2000-C-DMG) in isotonic phosphate buffered saline.  
ALN-TTR02 Solution for Injection contains 2 mg/mL of drug substance ALN-18328. 
The ALN-TTR02 drug product is packaged in 10 mL glass vials with a fill volume of 
5.5 mL.  The container closure system consists of a United States 
Pharmacopeia/European Pharmacopoeia (USP/EP) Type I borosilicate glass vial, a 
Teflon-faced butyl rubber stopper and an aluminium flip-off cap. 
5.2 
Preparation of Study Drug 
Each investigational site will be responsible for assembly and labelling according to 
separate IMP handling instructions and allocating treatments to the patients. 
The pharmacist will prepare the study drug under aseptic conditions.  The amount (in µg) 
of ALN-TTR02 to be administered will be determined based on the patient’s weight (kg) 
and the dose cohort they are assigned to.  For the first dose, the weight obtained pre-dose 
on Day 0 will be used to calculate the dose of study drug.  The patient’s weight measured 
pre-dose on Day 28 will be used to calculate the second dose of study drug.  Subjects 
who weigh 105 kg or more will receive ALN-TTR02 dosing based on an assumption of a 
body weight of 104 kg. 
Approximately 200 mL of sterile normal saline (0.9% NaCl) will be added to a sterile 
infusion bag, and the calculated volume of ALN-TTR02 will be withdrawn from the vials 
and injected into the infusion bag. 
Additional study drug preparation details are provided in the ALN-TTR02 Pharmacy 
Manual. 
5.3 
Storage of Study Drug 
All study drug must be stored in a secure location and may be dispensed only by the 
Investigator or by a staff member specifically authorized by the Investigator, or by a 
pharmacist, as appropriate.  All study medication will be stored upright and refrigerated 
at approximately 5 ± 3oC, protected from light in the storage area of the investigational

site pharmacy, in a secure, temperature controlled, locked environment with restricted 
access.  Any deviation from the recommended storage conditions should be reported to 
Alnylam and use of the study drug halted until authorization for its continued use has 
been given by Alnylam or designee. 
No special procedures for the safe handling of ALN-TTR02 are required.  Alnylam will 
be permitted upon request to audit the supplies, storage, dispensing procedures, and 
records. 
No trial product(s) may be administered to any person not enrolled in the trial. 
Additional preparation details are provided in the ALN-TTR02 Pharmacy Manual. 
5.4 
Labeling and Packaging of Study Drug 
All packaging and labelling as well as the production of study medication will be in 
compliance with Good Manufacturing Practice (GMP) specifications, as described in the 
Manufacture of Investigational Medicinal Products Volume 4 Annex 13, and any other or 
local applicable regulations. 
Study drug labels for use at study centers will include all appropriate local labeling 
requirements on the vial and external label.  Sample labels will be submitted to health 
authorities, per local country submission requirements. 
5.5 
Premedication Plan 
All patients will be premedicated prior to dosing with ALN-TTR02 to reduce the 
potential for an infusion reaction.   
Patients receiving the original premedication regimen will be administered the following: 
• 
Oral dexamethasone (8 mg) or equivalent administered the evening before dosing 
and 20 mg 30 to 60 minutes prior to start of infusion of ALN-TTR02; 
• 
Oral paracetamol (500 mg) or equivalent the evening before dosing and 30 to 
60 minutes prior to the start of infusion of ALN-TTR02; 
• 
Oral H2 blocker (e.g., ranitidine 150 mg, famotidine 20 mg, or equivalent other 
H2 blocker dose) the evening before dosing and 30 to 60 minutes prior to start of 
infusion of ALN-TTR02; 
• 
Oral H1 blocker, 10 mg cetirizine (hydroxyzine 25 mg, fexofenadine, or 
equivalent may be substituted if patient does not tolerate cetirizine) the evening 
before dosing and 30 to 60 minutes prior to start of infusion of ALN-TTR02.

Staff at each investigative site should make every effort to contact the patient by 
telephone the day prior to being administered the study drug (Days -1 and 27) to remind 
the patient of the premedication regimen. 
An alternative premedication regimen and infusion rate can be used in select optional 
cohorts, as agreed upon by the SRC.  The dosing regimen for the first optional cohort will 
be once every 4 weeks, and the dosing regimen for the remaining 4 optional cohorts will 
be once every 3 or 4 weeks.  It is anticipated that, the first 2 optional cohorts will use the 
original premedication regimen and the remaining 3 optional cohorts may be used to 
explore the alternative premedication regimen and infusion rate.  Patients in these cohorts 
will not receive any premedications the evening prior to ALN-TTR02 dosing.  Prior to 
each dose of ALN-TTR02, these patients will receive the following premedications: 
• 
Intravenous (IV) dexamethasone (10 mg) or equivalent, administered at least 60 
minutes prior to the start of infusion of ALN-TTR02; 
• 
Oral paracetamol (500 mg) or equivalent at least 60 minutes prior to the start of 
infusion of ALN-TTR02; 
• 
Intravenous H2 blocker (e.g., ranitidine 50 mg, famotidine 20 mg, or equivalent, 
other H2 blocker dose) at least 60 minutes prior to start of infusion of ALN-
TTR02; and 
• 
Intravenous H1 blocker: diphenhydramine 50 mg IV (or equivalent other IV H1 
blocker available at the study site) at least 60 minutes prior to start of infusion of 
ALN-TTR02.  Hydroxyzine or fexofenadine 25 mg PO or cetirizine 10 mg PO 
may be substituted for any patient who does not tolerate IV diphenhydramine or 
other IV H1 blockers. 
Further details can be found in the Study Reference Manual.   
5.6 
Dose, Route, and Schedule of Study Drug Administration 
Consented patients meeting the eligibility criteria will be enrolled into sequential cohorts 
of increasing doses of ALN-TTR02.  Each cohort will consist of 3 patients. 
Study drug will be administered under the supervision of the Investigator or designee.  
Study drug doses will be administered as a 60-minute IV infusion (flow rate of 
approximately 3.3 mL/min) 4 weeks apart.  The dosing of ALN-TTR02 in the optional 
cohorts will be once every 4 weeks for the first optional cohort and once every 3 or 
4 weeks for the remaining 4 optional cohorts, at a dose previously determined by the SRC 
to be safe and tolerable.  Study drug will be administered via a controlled infusion device

with an extension set containing a 1.2 micron filter supplied by Alnylam or designee.  
Infusion products containing polyvinyl chloride, di(2-ethylhexyl)phthalate (PVC, DEHP) 
must NOT be used.  For patients enrolled in an optional cohort evaluating the alternative 
premedication regimen, the flow rate will be approximately 1.1 mL/min during the first 
15 minutes (1/3rd the original flow rate) with the remainder of the infusion taking place 
over 55 minutes (at a flow rate of approximately 3.3 mL/min) for a total infusion time of 
approximately 70 minutes. 
The patient’s infusion site will be checked pre-dose, during infusion, and after infusion 
for any safety concerns (e.g., infusion-associated reactions).  The infusion time may be 
extended up to 3 hours in the event of a mild or moderate infusion reaction (study drug 
administration will not be resumed for any patient following a severe infusion reaction).  
Patients will remain hospitalized at the study site for at least 24 hours following 
completion of dosing on Day 0 and Day 28 to be observed for safety assessments and PK 
sampling. 
The planned study drug doses are 10, 50, 150, and 300 µg/kg. 
Subjects who weigh 105 kg or more will receive ALN-TTR02 dosing based on an 
assumption of a body weight of 104 kg. 
Prior to administration of the second dose of ALN-TTR02, the inclusion and exclusion 
criteria must be reassessed to ensure that the patient still qualifies for participation in the 
study.

Up to 5 optional cohorts may be included to confirm the safety, tolerability, and/or PD effect of previously 
evaluated dose levels, which may include evaluation of the original dosing regimen (once every 4 weeks), an 
alternative dosing regimen (once every 3 weeks), and/or an alternative premedication regimen and infusion rate at 
a specific dose of ALN-TTR02.  Dosing in these optional cohorts may occur at a previously tested dose that was

be comprised of 3 patients. 
5.7 
Criteria for Dose Escalation, Dose Modification or Discontinuation of 
Study Drug 
5.7.1 
Dose Escalation Procedures 
The initial dose of ALN-TTR02 is 10 µg/kg.  Dose escalation to 50, 150, and 300 µg/kg 
is planned.   
Within each of the cohorts, the first patient will receive their first dose and if the dose is 
well tolerated, per Section 5.7.3 (Dose-limiting Toxicity), Patients 2 and 3 will receive 
their first dose at that same dose level no sooner than 48 hours apart, with Patient 2 
receiving a dose of study drug no sooner than 48 hours after the dosing of Patient 1.  
Similar to the first dose, the second dose will be administered to patients 4 weeks after 
the first dose in a sequential manner with at least 48 hours separating dosing of each 
patient.  If after the first dose, ALT and AST are > 2.5 x ULN, that patient would not 
receive their second dose.  Dose escalation to the next cohort will proceed after the 
collective safety and tolerability data through at least 96 hours post-first dose from the 3 
patients in the previous cohort has been reviewed by the SRC.  If the administered dose is 
found to be safe and well tolerated, dosing for the next cohort will begin no sooner than 
96 hours after Patient 3 has safely received dose 1 from the previous cohort.  Patients in 
the cohort would be dosed and reviewed for safety and tolerability following the same 
procedures as used for other cohorts (as stated above).

Dose-limiting toxicities are described further in Section 5.7.3, and study stopping rules 
are described in Section 5.7.4.  
5.7.2 
Optional Cohorts 
Based on the interim evaluation of safety data, it may also be decided by the SRC that an 
optional cohort may be utilized which will include 3 additional patients.  Dosing in these 
optional cohorts may occur at a previously tested dose that was found to be safe and 
where stopping rules were not met or at an intermediate dose level.  Patients in the 
optional cohort would be dosed and reviewed for safety and tolerability following the 
same procedures as used for other cohorts.  The optional cohort would be included to 
further confirm the safety and/or PD effect of previously evaluated dose levels, which 
may include evaluation of the original dosing regimen (once every 4 weeks), an 
alternative dosing regimen (once every 3 weeks), and/or to evaluate an alternative 
premedication regimen and infusion rate.  The dosing regimen for the first optional 
cohort will be once every 4 weeks, and the dosing regimen for the remaining 4 optional 
cohorts will be once every 3 or 4 weeks.  It is anticipated that the first 2 optional cohorts 
will use the original premedication regimen, and the remaining 3 optional cohorts may be 
used to explore the alternative premedication regimen and infusion rate.  The SRC will 
review all available safety data and make recommendations on dosing and premedication 
regimens prior to dosing of any of the optional cohorts.  If this occurs, the IECs will be 
informed of the implementation of optional cohorts.  Up to 5 optional cohorts of 
3 patients each are permitted in this study. 
5.7.3 
Dose-limiting Toxicity 
A DLT is defined as: 
• 
Any life-threatening toxicity; 
• 
ALT and AST levels ≥5 × ULN or total bilirubin >2.0 mg/dL; 
• 
An infusion reaction that requires hospitalization, despite premedication; 
• 
Any other toxicity which in the opinion of the SRC would have precluded further 
dosing. 
5.7.4 
Stopping Criteria 
For any DLT, accrual to that dose level will stop, all dosing will be discontinued, and 
dose escalation will end, pending further evaluation of all available safety data by the 
SRC.

5.8 
Measurement of Patient Compliance 
Patient compliance with study drug administration is dependent on the proper preparation 
and administration of IV infusions by study center personnel.  Because the study drug 
will be administered by study staff as an IV infusion, treatment compliance will be 
verified by observation in the clinic by study staff.  Treatment will be considered 
completed if 80% or more of each of the doses (based on total volume of the IV solution) 
has been administered to the patient. 
5.9 
Study Drug Accountability 
The Investigator will maintain accurate records of receipt and the condition of all study 
drugs including dates of receipt.  In addition, accurate records will be kept of when and 
how much study drug is dispensed and used by each patient in the study.  Any reasons for 
departure from the protocol dispensing regimen must also be recorded. 
Drug accountability records and inventory will be available for verification by Alnylam 
Monitor or designee.  Remaining study drug (all used, partially used and unused vials) 
will be returned to Alnylam or its specified designee/depot or destroyed at the site 
according to applicable regulations. 
Study drug must not be used for any purpose other than the present study.  Study drug 
which has been dispensed to a patient and returned unused must not be redispensed to a 
different patient. 
Further instructions about study drug accountability are detailed in the Pharmacy Manual. 
5.10 
Concomitant Medication / Treatment 
Use of the following medications/treatments is prohibited during study participation: 
• 
Any investigational agent other than ALN-TTR02, tafamidis, or diflunisal; 
• 
Corticosteroids, other than those administered as premedications prior to the dose 
of ALN-TTR02, those used to treat an infusion reaction, or topical or inhaled 
corticosteroids. 
Medications and treatments other than those specified above, including palliative and 
supportive care for disease-related symptoms, are permitted during the study. 
Use of all concomitant medications during screening, pre-dose and post-dose up to 
Day 56/ET will be recorded on the patient’s CRF.  This will include all prescription

drugs, herbal preparations, over-the-counter (OTC) medications, vitamins, and minerals.  
Any changes in medications during the study will also be recorded on the CRF. 
Any concomitant medication that is required for the patient’s welfare may be given by 
the Investigator.  However, it is the responsibility of the Investigator to ensure that details 
regarding the medication are recorded on the CRF, and coded using an internationally 
recognized and accepted coding dictionary. 
5.11 
Suggested Guidelines for Management of Infusion Reactions 
In the event of an acute infusion reaction, the infusion of study drug will be stopped and 
the patient closely monitored until resolution of the reaction.  A blood sample should be 
obtained for analysis of tryptase, complement factors (including C3a), and cytokines at 
the time of the event, or as soon as possible after onset, 1 hour, and 24 hours after the 
start of the reaction.  In addition, if the infusion is stopped and the site is considering 
restarting, a PK blood sample will be taken when the infusion is stopped and this will be 
treated as the EOI sample if the infusion is restarted. 
Drugs that may be used to facilitate resolution and permit resumption of study drug 
administration include, but are not limited to: paracetamol (or equivalent), additional 
H1/H2 blockers (e.g., ranitidine), non-steroidal anti-inflammatory [NSAID], adrenaline, 
supplemental oxygen, IV fluids, and corticosteroids.  For moderate infusion reactions 
(see Appendix 1), resumption of study drug administration at a slower infusion rate (but 
not to exceed 3 hours) may be considered at the Investigator’s discretion.  Study drug 
administration will not be resumed for any patient following a severe infusion reaction.  
If the infusion is delayed, the administration of the infusion should be completed no more 
than 6 hours from the initial start of the infusion. 
Infusion reactions may have a delayed onset following the completion of the infusion.  
The medical management of a delayed reaction (e.g., use of corticosteroids, etc.) would 
follow similar guidelines as provided above for acute infusion reactions (see Appendix 
2). 
After dosing, patients will be discharged from the hospital no sooner than 24 hours post-
dose.  Prior to discharge, the 24-hour ECG and local serum chemistries and LFTs must be 
reviewed by the Investigator as described in Section 3.1.  Patients will be discharged with 
directions on self-administration of medications as needed to ameliorate potential delayed 
reactions to study drug infusion, such as fever, chills, and myalgia.  Medications may

include, but are not limited to: antipyretics, antihistamines, and oral corticosteroids.  All 
concomitant medications, including self-administered medications, are to be listed on the 
CRF.

STUDY VISITS 
The duration of a patient’s participation in this study is approximately 36 weeks.  This 
duration may be extended should optional cohorts with dosing intervals greater than 
4 weeks be included. 
An open-label extension study at the recommended Phase 3 dose and regimen (as derived 
from Study ALN-TTR02-002) is planned, which will enable the patients who enrolled in 
Study ALN-TTR02-002 to receive additional, long-term dosing and safety follow-up.  
For some of the patients, this may preclude the completion of all of the follow-up period 
assessments of Study ALN-TTR02-002 if they are deemed eligible to participate in the 
extension study prior to completion of the full follow up through Day 208.  Such patients 
will be followed up for a minimum of 28 days after their last dose in the current ALN-
TTR02-002 study prior to being enrolled in the extension study.  The extension study will 
be implemented only after dose escalation is completed in Study ALN-TTR02-002, with 
post second dose follow-up through Day 208 in at least 1 cohort at the highest dose. 
Screening evaluations are to be performed within 45 days before receiving the first dose 
of study drug, as indicated in Table 1-1 (Appendix 4 provides the schedule of 
assessments for the optional cohort(s) administered ALN-TTR02 once every 3 weeks). 
Patients determined to be eligible based on screening assessments will receive treatment 
(IV infusion of study drug) on Days 0 (Baseline) and 28 (or date of second dose 
administration in optional cohorts with dosing intervals greater than 4 weeks); for 
patients in optional cohorts evaluating the alternative dosing regimen (once every 
3 weeks), ALN-TTR02 will be administered on Days 0 (Baseline) and 21.  Patients will 
remain hospitalized at the study site for at least 24 hours following completion of dosing 
to be observed for safety assessments and PK sampling.  Patients will return to the study 
site on Days 2, 7, 10, 14, and 21 for follow-up assessments.  In addition, follow-up visits 
after the second dose of study drug (Day 28) will occur on Days 30, 35, 38, 42, 49, and 
56 (end-of-study); patients in optional cohorts evaluating the alternative dosing regimen 
(once every 3 weeks) will have follow-up visits on Days 21, 22, 23, 28, 31, 35, 42, 49, 
and 56.  Patients will also return to the site for a follow-up visit on Days 112 and 208. 
If necessary, visiting nurses will be allowed to conduct visits after Day 2 (but not 
Day 208) that do not require physical examinations.  All patients who discontinue the 
study before Day 56 will return to the study site for their Early Termination visit for 
Day 56 assessments.  All patients who discontinue the study after Day 56 and prior to

assessments. 
6.1 
Screening Visit (Day -45 to -3) 
Screening evaluations will be conducted 3 to 45 days prior to administration of the first 
dose of study drug (Day 0).  Table 1-1 provides an overview of the schedule of events 
required for screening. 
Prior to screening activities, the patient will sign and date an informed consent form 
(ICF) and receive a copy of the signed ICF.  No study procedures should be performed 
prior to informed consent being obtained.  The Investigator or another person authorized 
by the Investigator will also sign and date the informed consent prior to giving a copy to 
the patient.  The ICF will be filed in the patient’s medical record. 
The following activities should be performed during the Screening visit: 
• 
Obtain demographic information. 
• 
Obtain medical detailed history information. 
• 
Assess study eligibility using the inclusion and exclusion criteria (e.g., calculate 
BMI). 
• 
Obtain concomitant medications information. 
• 
Perform a physical examination. 
• 
Obtain measurements of weight and height. 
• 
Measure vital signs. 
• 
Perform an echocardiogram if a normal echocardiogram has not been obtained

For those patients receiving the original premedication regimen, on the day prior to 
administration of study drug (Days -1 and 27), study site personnel will contact the 
patient by phone to discuss the pretreatment medication they are to take that evening. 
On the evening before each dosing, patients are to self-administer the following 
medications PO: 8 mg dexamethasone or equivalent, 500 mg paracetamol or equivalent, 
an H1 blocker (10 mg cetirizine hydroxyzine [25 mg, fexofenadine, or equivalent may be 
substituted if patient does not tolerate cetirizine]), and an oral H2 blocker (e.g., ranitidine 
150 mg, famotidine 20 mg, or equivalent other H2 blocker). 
Patients in an optional cohort evaluating the alternative premedication regimen and 
infusion rate will not receive any premedication the evening prior to ALN-TTR02 dosing.

6.6 
Participation in an Open-label Extension Study 
An open-label extension study at the recommended Phase 3 dose and regimen (as derived 
from Study ALN-TTR02-002) is planned, which will enable the patients who enrolled in 
Study ALN-TTR02-002 to receive additional, long-term dosing and safety follow-up.  
For some of the patients, this may preclude the completion of all of the follow-up period 
assessments of Study ALN-TTR02-002 if they are deemed eligible to participate in the 
extension study prior to completion of the full follow up through Day 208.  Such patients 
will be followed up for a minimum of 28 days after their last dose in the current ALN-
TTR02-002 study prior to being enrolled in the extension study.  The extension study will 
be implemented only after dose escalation is completed in Study ALN-TTR02-002, with 
post second dose follow-up through Day 208 in at least 1 cohort at the highest dose 
deemed safe.

STUDY ASSESSMENTS 
7.1 
Demographic Data and Medical History 
Patient demographic data will be obtained during screening, and a complete medical 
history will be obtained during screening and updated on Days 0 and 28 (or Days 0 and 
21 for optional cohorts dosed once every 3 weeks) as needed.  The medical history is to 
include background information confirming a diagnosis of ATTR through biopsy and 
ongoing documented signs/symptoms of the disease (e.g., sensory, motor, or autonomic 
neuropathy) that are at least mild to moderate in severity. 
7.2 
Safety Assessments 
All safety assessment measures will be recorded in the patient’s CRF. 
7.2.1 
Physical Examination 
Physical examinations will be performed by a physician and will include the examination 
of the following: general appearance, head, eyes, ears, nose, throat, chest/respiratory, 
heart/cardiovascular, gastrointestinal/liver, musculoskeletal/extremities, 
dermatological/skin, thyroid/neck, lymph nodes, and neurological/psychiatric.  
Body weight will be measured at Screening for assessment of eligibility, and on the 
Day 0 and 28 (or Days 0 and 21 for optional cohorts dosed once every 3 weeks) study 
visits.  The weight measured pre-dose on Days 0 and 28 will be used to calculate the first 
and second dose of ALN-TTR02, respectively. 
Height will be measured at Screening. 
7.2.2 
Vital Signs 
Vital signs are to be measured at Screening and the Day 2, 14, 30, 42, and 56 (or Days 2, 
14, 23, 35, and 56 for optional cohorts dosed once every 3 weeks; or time of early 
termination, if applicable) study visits and include systolic/diastolic blood pressure, pulse 
rate, respiration rate, and oral body temperature.  Vital signs will be measured in the 
supine position using an automated instrument after the patient has rested comfortably for 
10 minutes.  Each patient’s blood pressure should be taken using the same arm.  Oral 
temperature will be recorded in Celsius.  Heart rate will be counted for a full minute and 
recorded in beats per minute.  Respirations will be counted for a full minute and recorded 
in breaths per minute.

Amendment 2.1 
Page 72 of 116 
On Days 0 and 28 (or Days 0 and 21 for optional cohorts dosed once every 3 weeks), 
serial vital signs are to be measured within 30 minutes pre-dose, at EOI; and at 
30 (±5) minutes;1, 2, and 3 (±15 minutes) hours; 6, 12, and 18 hours (±30 minutes) post-
infusion.  On Days 1 and 29 (or Days 1 and 22 for optional cohorts dosed once every 
3 weeks), serial vital signs are to be measured at 24 hours (+30 minutes) post-infusion. 
For the safety of the patient, additional vital signs may be added at the discretion of the 
Investigator. 
7.2.3 
Echocardiogram 
An echocardiogram is to be conducted during Screening, to assess any cardiac 
abnormalities as part of the screening criteria.  If a normal echocardiogram has been 
obtained within the past 90 days, there is no need to perform an echocardiogram at 
Screening. 
7.2.4 
Electrocardiogram 
Computerised 12-lead ECG recordings will be obtained.  Each lead shall be recorded for 
at least 3 beats at a speed of 25 mm/s.  Triplicate recordings will be made at the time 
points indicated in Table 1-1. 
Serial ECGs will be collected in triplicate 30 minutes prior to dosing (Days 0 and 28 [or 
Days 0 and 21 for optional cohorts dosed once every 3 weeks]), EOI, and 30 (±5) 
minutes, 2 and 4 (±15 minutes) hours, and on Days 1 and 29 (or Days 1 and 22 for 
optional cohorts dosed once every 3 weeks) at 24 (+30 minutes) hours post-infusion. 
The following electrophysiologic parameters will be assessed: rhythm, ventricular rate, 
PR interval, QRS duration, and QT interval.  Either Bazett’s and/or Fridericia’s formula 
will be used to calculate the heart rate corrected QT interval (QTc). 
The Investigator or designee is responsible for reviewing the ECG to assess whether the 
ECG is within normal limits and to determine the clinical significance of the results.  
Prior to discharge from the hospital on Days 1 and 29 (or Days 1 and 22 for optional 
cohorts dosed once every 3 weeks), the ECG must be reviewed by the Investigator and 
the results deemed not clinically significant.  Any clinically significant findings must be 
discussed with the medical monitor to determine whether patient can be discharged and 
to formulate plans for patient follow-up.

For any clinically significant abnormal results, the Investigator must contact the Medical 
Monitor to discuss continued participation of the patient in the study (e.g., ischemic ECG 
changes, wave/interval changes, or arrhythmia).  
7.2.5 
Pulse Oximetry 
Arterial oxygen saturation will be assessed by serial pulse oximetry on Days 0 and 28 (or 
Days 0 and 21 for optional cohorts dosed once every 3 weeks) within 30 (±5) minutes 
pre-dose; at EOI; at 30 (±5) minutes; at 1, 2, 3 hours (±15 minutes); and at 6, 12, and 
18 hours (±15 minutes) post-infusion on Days 0 and 28 (or Days 0 and 21 for optional 
cohorts dosed once every 3 weeks); and at 24 hours (+30 minutes) post-infusion on 
Days 1 and 29 (or Days 1 and 22 for optional cohorts dosed once every 3 weeks). 
7.2.6 
Cardiac Monitoring 
Continuous cardiac monitoring will be performed via telemetry starting no later than 30 
minutes prior to dosing and continuing through 24 hours (+1 hour) post-dose. 
7.2.7 
Clinical Laboratory Tests 
Laboratory tests of hematology, serum chemistries, liver function, coagulation studies, 
CRP, urinalysis, pregnancy (serum and urine), hepatitis B and C serologies, lipids, and

Pharmacokinetic Evaluations 
7.4.1 
Plasma Pharmacokinetics 
The PK parameter estimates and dose proportionality profiles of ALN-TTR02 will be 
determined for ALN-TTR02 siRNA (ALN-18328) and liposome lipid components, 
DLin-MC3-DMA and PEG2000-C-DMG.  The plasma concentration-time profiles for 
ALN-18328, DLin-MC3-DMA, and PEG2000-C-DMG will be determined and used in the 
PK analysis for all dose cohorts.  In addition, free and encapsulated concentrations of 
siRNA will be determined in plasma at specified time points (see Table 1-1) for cohort 3 
and onward, including any optional cohorts.  The drug concentrations in the lower 
cohorts are expected to be undetectable for this analysis. 
Blood sample collection times are included in the schedule of events (see Table 1-1).  
Plasma PK samples (siRNA and lipids) will be collected pre-dose (within 1 hour of 
planned dosing start), at EOI, and then 5, 10, and 30 minutes, and at 1, 2, 4, 6, 24, and 
48 hours post infusion.  Samples will also be collected on Days 7, 14, 21, 35, 42, 49, 56, 
112, and 208 post infusion as well as at the ET visit (if applicable); for optional cohorts

dosed once every 3 weeks, samples will be collected on Days 7, 14, 21, 28, 35, 42, 56, 
112, and 208 post infusion as well as at the ET visit (if applicable). 
For the PK blood draws, the sampling windows are ±1 minute for the 5- and 10- minute 
draws; ±2 minutes for the 30-minute draws; ±5 minutes for the 1-, 2-, 4-, and 6-hour 
draws; and ±120 minutes for the 24- and 48-hour draws. 
The EOI will usually occur at 60 minutes after the start of infusion, except in patients 
where the infusion has been prolonged.  If the infusion is stopped, a PK blood sample 
will be taken when the infusion is stopped, and this sample will be treated as the EOI 
sample if the infusion is restarted.  All remaining PK samples will be collected according 
to the schedule of assessments when the dose is completed (i.e., all post-infusion times 
are relative to the EOI, regardless of the duration of infusion). 
In the event that a patient receives only 1 dose of study drug, plasma PK samples should 
be collected pre-dose (within 1 hour of planned dosing start), EOI, and then 5, 10, and 
30 minutes; and 1, 2, 4, 6, 24 and 48 hours post infusion; and at Day 208. 
Details of sample collection and processing for PK analyses will be included in a 
laboratory manual.

REPORTING ADVERSE EVENTS 
8.1 
Adverse Event Definition 
An AE is any untoward medical occurrence in a patient or clinical investigational patient 
administered a pharmaceutical product and which does not necessarily have a causal 
relationship with this treatment. 
An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding, for example), symptom, or disease temporally associated with the use 
of a medicinal product, whether or not considered related to the medicinal product. 
8.2 
Serious Adverse Event Definition 
An SAE is any untoward medical occurrence that at any dose: 
• 
Results in death; 
• 
Is life-threatening (an event which places the patient at immediate risk of death 
from the event as it occurred.  It does not include an event that had it occurred in a 
more severe form might have caused death); 
• 
Requires inpatient hospitalization or prolongation of existing hospitalization; 
• 
Results in persistent or significant disability/incapacity; 
• 
Is a congenital anomaly or birth defect; 
• 
An important medical event that may not be immediately life-threatening or result 
in death or hospitalization but may jeopardize the patient or may require 
intervention to prevent one of the other outcomes listed in the definition above 
(e.g., such events include allergic bronchospasm, blood dyscrasias or convulsions, 
or the development of drug dependency or abuse). 
8.3 
Eliciting Adverse Event Information 
The patient should be asked about medically relevant changes in his/her health since the 
last visit.  The patient should also be asked if he/she has been hospitalized, had any 
accidents, used any new medications, or changed concomitant medication routines (both 
prescription and OTC). 
In addition to patient observations, AEs will be documented from any laboratory 
findings, physical examination findings, ECG changes or other documents.

Amendment 2.1 
Page 84 of 116 
8.4 
Adverse Event Reporting 
The Investigator is responsible for reporting all AEs that are observed or reported after 
the first dose of study drug regardless of their relationship to study drug through to 
Day 56. 
Any medical condition that is present when a patient is screened and does not deteriorate 
should not be reported as an AE.  However, if it does deteriorate at any time during the 
study, it should be reported as an AE. 
All AEs must be fully recorded for 28 days from the start of infusion in the site’s source 
records and in the patients’ CRF, whether or not they are considered to be drug-related.  
Each AE should be described in detail: onset time and date, description of event, severity, 
relationship to investigational product, action taken, and outcome (including time and 
date of resolution, if applicable). 
Adverse events should be followed for 28 days following the last dose of study drug or 
until recovery to the normal state has been achieved, whichever occurs first. In the event 
of a patient not returning to the clinical unit, the outcome of this event will be recorded as 
lost at follow up. 
8.5 
Adverse Event Reporting Period 
As stated in Section 8.4, AEs will be assessed for 28 days following the last dose of study 
drug (Day 56 for patients receiving both doses of ALN-TTR02) or until recovery to the 
normal state has been achieved, whichever occurs first; all AEs that occur after the start 
of study drug administration on Day 0 (Baseline) must be reported in detail on the 
appropriate CRF page and followed to satisfactory resolution, or a period of 28 days after 
the last dose of study drug administration, whichever is shorter.   
Serious AEs will be followed for 28 days following the last dose of study drug (Day 56 
for patients receiving both doses of ALN-TTR02), or until satisfactory resolution, or until 
the SAE is considered by the Investigator to be chronic or the patient is stable, whichever 
occurs first. 
8.6 
Assessment of Causality 
Causal relationship assessment to drug treatments is required for purposes of reporting 
AEs.  To promote consistency, the following guidelines should be taken into

considerations along with good clinical and scientific judgment when determining the 
relationship of drug treatments to an AE: 
Definitely Related: 
A clinical event, including laboratory test abnormality, occurring in 
a plausible time relationship to the medication administration, and 
which cannot be explained by concurrent disease or other drugs or 
chemicals.  The response to withdrawal of the drug should be 
clinically plausible. 
Possibly Related: 
A clinical event, including laboratory test abnormality, with a 
reasonable time sequence to the medication administration, but 
which could also be explained by concurrent disease or other drugs 
or chemicals.  Information on the drug withdrawal may be lacking 
or unclear. 
Unlikely Related: 
A clinical event, including laboratory test abnormality, with little or 
no temporal relationship to medication administration, and which 
other drugs, chemicals or underlying disease provide plausible 
explanations. 
Not Related: 
A clinical event, including laboratory test abnormality that has no 
temporal relationship to the medication or has more likely 
alternative etiology. 
8.7 
Assessment of Severity 
Adverse events are to be graded according to the categories detailed below. 
Mild: 
Mild events are those which are easily tolerated with no disruption 
of normal daily activity. 
Moderate: 
Moderate events are those which cause sufficient discomfort to 
interfere with daily activity. 
Severe:  
Severe events are those which incapacitate and prevent usual 
activity. 
Changes in severity should be documented in the medical record to allow assessment of 
the duration of the event at each level of severity.  Adverse events characterized as 
intermittent require documentation of the start and stop of each incidence.  When changes

in the severity of an AE occur more frequently than once a day, the maximum severity 
for the experience that day should be noted.  If the severity category changes over a 
number of days, then those changes should be recorded separately (with distinct onset 
dates). 
8.8 
Action Taken for Adverse Event 
Action taken in regards to study medication will be defined as: 
• 
None; 
• 
Infusion interrupted and restarted at a later time; 
• 
Infusion stopped and was not restarted at a later time. 
8.9 
Outcome of Adverse Event 
Outcome will be defined as: 
• 
Resolved (with or without sequelae); 
• 
Ongoing; 
• 
Lost to follow up. 
8.10 
Coding of Adverse Events 
The Medical Dictionary for Regulatory Activities (MedDRA) will be used to code AEs. 
8.11 
Serious Adverse Event Reporting 
An assessment of the seriousness of each AE will be made by the Investigator.  Any AE 
and laboratory abnormality that meets the above seriousness criteria (Section 8.2) must 
be reported immediately to Alnylam, always within 24 hours from the time that site 
personnel first learn of the event.  Every SAE must be documented by the Investigator on 
the Serious Adverse Event Report in addition to the documentation on the AE form in the 
CRF.  All SAEs must be reported regardless of the relationship to study drug. 
The initial report should include at least the following information: 
• 
Patient’s study number. 
• 
Description and date of onset of the event. 
• 
Criterion for serious. 
• 
Preliminary assignment of causality to study drug.

If follow up is required, new information should be provided to Alnylam as it becomes 
available using the Serious Adverse Event Reporting form.  Copies of discharge 
summaries, consultant reports, autopsy reports, and any other relevant documents may 
also be requested. 
Appropriate remedial measures should be taken by the Investigator using his/her best 
medical judgment to treat the SAE.  These measures and the patient’s response to these 
measures should be recorded.  All SAEs, regardless of relationship to study drug, will be 
followed by the Investigator until satisfactory resolution or the Investigator deems the 
SAE to be chronic or stable.  Clinical, laboratory, and diagnostic measures should be 
employed by the Investigator as needed to adequately determine the etiology of the event.   
The Investigator will be responsible for reporting all SAEs to the local IEC when 
required by national regulations. 
Alnylam will be responsible for the reporting of all relevant events to the concerned 
regulatory authorities according to all applicable regulations. 
In Europe, in accordance with the Directive 2001/20/EC, the Competent Authorities and 
the Ethics Committees in the concerned Member States will be notified of fatal and life-
threatening Suspected Unexpected Serious Adverse Reactions (SUSARs) as soon as 
possible but no later than 7 calendar days after Alnylam has first knowledge of the 
minimum criteria for expedited reporting.  Non fatal and non life-threatening SUSARs 
should be reported no later than 15 calendar days after Alnylam has first knowledge of 
them. 
The Investigator may be informed by Alnylam of SAEs from other Investigators or 
clinical studies which may have relevance to this clinical trial.  These SAEs should also 
be reported promptly to the IEC or Clinical Events Committee (CEC) which approved the 
study.  All SAE reports should be transmitted to the IEC/CEC with a cover letter or

Pregnancy Reporting 
A female patient with a positive pregnancy test at Screening or Day 0 is ineligible for this 
trial.  If a female patient is determined to be pregnant within 2 months after receiving 
study drug, the Investigator should report the pregnancy to Alnylam within 24 hours of 
being notified of the pregnancy.  Details of the pregnancy will be recorded on the 
pregnancy reporting form.  The patient should receive any necessary counseling 
regarding the risks of continuing the pregnancy and the possible effects on the fetus.  
Monitoring of the patient should continue until the outcome of the pregnancy is known.   
Pregnancy occurring in the partner of a patient participating in the study should also be 
reported to the Investigator and Alnylam.  The partner should be counseled and followed 
as described above.

STATISTICAL METHODS 
9.1 
Sample Size 
Based on the planned dose escalation scheme (see Section 5.7.1), up to 27 patients are 
expected to be enrolled.  Three patients are to be enrolled at each of 5 planned dose 
levels.  An additional 3 cohorts of 3 patients may be enrolled onto 1 or more of these 
specified dose levels to further evaluate safety and tolerability or PD effects. 
9.2 
Statistical Methodology 
Statistical analyses will be primarily descriptive in nature.  Adverse event summaries will 
include tabulations of all treatment-emergent AEs, treatment-related AEs, SAEs, 
discontinuations due to AEs, and AEs of various grading severity.  By-patient listings 
will be provided for deaths, SAEs, and AEs leading to discontinuation of treatment. 
Descriptive statistics will be provided for clinical laboratory data, vital signs data, and 
ECG interval data, presented as both actual values and changes from baseline relative to 
each on-study evaluation.  Laboratory shift tables from baseline to worst values will be 
presented. 
Tabulations will be presented by dose level.  For categorical variables, summary 
tabulations of the number and percentage of patients within each category (with a 
category for missing data) will be presented.  For continuous variables, the number of 
patients, mean, median, standard deviation, minimum, and maximum values will be 
presented. 
All data will be provided in by-patient listings. 
9.2.1 
Populations to be Analyzed 
The following patient populations (i.e., analysis sets) may be evaluated and used for 
presentation of the data: 
• 
Intent-to-Treat (ITT) Analysis Set:  All patients who were enrolled and received 
study treatment.  The ITT analysis set will be the primary set for the analysis of 
safety data. 
• 
Per-Protocol (PP) Analysis Set:  All patients in the ITT Analysis Set who had no 
major protocol violations.  
• 
Pharmacokinetic (PK) Analysis Set:  All patients in the ITT Analysis Set who 
have adequate data to determine a full PK profile.

9.2.2 
Baseline Evaluations 
Demographic and baseline disease characteristic data will be summarized in order to 
descriptively assess the comparability of dose groups.  Data to be tabulated will include 
sex, age, and race, as well as disease-specific information. 
9.2.3 
Safety Analyses 
A summary of study drug exposure, including the duration of the infusion and dose, and 
the proportion of patients with modifications in the duration of infusion will be produced. 
Adverse events will be summarized by MedDRA system organ class and preferred term.  
Separate tabulations will be produced for all treatment emergent AEs, treatment-related 
AEs (those considered by the Investigator as at least possibly drug related), SAEs, and 
discontinuations due to AEs.  By-patient listings will be provided for deaths, SAEs, 
DLTs, and events leading to discontinuation of treatment. 
Descriptive statistics will be provided for clinical laboratory data, including cytokines, as 
well as vital signs data, presented as both actual values and changes from baseline 
relative to each on-study evaluation and to the last evaluation on study. 
Descriptive statistics will be provided for ECG interval data and presented as both actual 
values and changes from baseline relative to each on-study evaluation and to last 
evaluation on study. 
9.2.4 
Pharmacodynamics 
Serial measurements of serum TTR over a 208-day period post-dose will allow for 
determination of the nadir following dosing as well as the timing of the nadir post-dose 
and the duration of TTR suppression.  A standard ELISA assay will be used to measure 
serum total TTR in patients.  Also, TTR testing will be performed as a LC/MS assay, to 
measure mutant and WT TTR.   
Pre- and post-dose measurements of serum TTR mRNA will assist in determining 
whether any observed effects of ALN-TTR02 on TTR protein are being mediated by 
RNAi.  Transthyretin mRNA in the serum will be detected using a qRT – PCR based 
assay. 
9.2.5 
Pharmacokinetics 
Pharmacokinetic analyses will consist of a non-compartmental and/or compartmental 
evaluation of siRNA ALN-18328 of ALN-TTR02 and DLin-MC3-DMA and PEG2000-C-
DMG plasma concentration-time profile to determine PK parameter estimates using a

validated software program, 
  Pharmacokinetic parameter estimates to be 
calculated for all patients receiving ALN-TTR02 will include, but may not be limited to: 
Cmax; tmax; t½β; t1/2α, AUCp, AUC0-t, AUC0-last and AUC0-∞; λz; CL, Vss and Vz.  The dose 
proportionality of ALN-TTR02 following a single, 15-minute infusion will also be 
determined. 
Plasma and urine samples will be evaluated by 
 using a validated 
hybridization enzyme-linked immunosorbent assay for each of the two siRNAs (both 
encapsulated and unencapsulated).  Analysis of the concentration-time data will also be 
performed by 
.  The methods will be validated as per 
 
 Standard Operating Procedures.  The PK profile of each patient will be 
characterized by non-compartmental analysis of each siRNA plasma concentration using 
validated computer software
 
.  Parameters will include, but may not be limited to: Cmax, tmax, AUC, CL, Vss, and 
Vz.  The AUC will be calculated using the linear trapezoidal method (linear 
interpolation).  Other parameters may be calculated, if deemed necessary.  If possible, the 
terminal elimination phase of the PK profile will be identified and its slope calculated 
using log-linear regression.  The coefficient of determination of the line fitted to the 
terminal elimination phase will be calculated.  Pharmacokinetic parameters describing the 
systemic exposure of the test article in the test system will be estimated from observed 
plasma concentration values for each patient.  The amount of siRNA excreted in the urine 
over the 2 separate and combined collection intervals will be determined and CLR 
calculated for each patient, if possible. 
9.2.6 
Summary of Pharmacodynamic and Pharmacokinetic Analyses 
Pharmacokinetic and PD data will be assessed descriptively whenever possible and by 
exploratory statistical comparisons.  Pharmacokinetic/PD analyses will include 
evaluation with respect to siRNA ALN-18328 of ALN-TTR02 plasma concentrations, 
exposure, or the relationship of any PK/PD parameter estimate to TTR concentration 
after ALN-TTR02 following a single, 15-minute infusion.  Attempts will be made to 
perform PK/PD analysis to determine PK/PD parameters (e.g., ED50, EC50[50% effective 
dose, 50% effective concentration, respectively]).

Study Committees 
An SRC will be formed that will evaluate safety and tolerability data and determine if it 
remains acceptable to continue dosing (administration of second dose of study drug 
within cohorts) or to dose escalate (between cohorts).  The SRC will also be convened in 
the event of any potential DLT to determine whether stopping rules for accrual to a 
particular dose level have been met (see Section 5.7.4 for study stopping rules).  The SRC 
is also responsible for making recommendations regarding replacement of subjects that 
have withdrawn before Day 56 without experiencing a DLT.  In addition, the SRC may 
be convened at the discretion of Alnylam if important safety issues arise requiring the 
attention of the committee (e.g., new safety information attained in other ongoing studies 
with ALN-TTR02). 
To ensure timely safety information exchange across the participating study centres, the 
SRC will be comprised of all Principal Investigators participating in the study, or their 
designee, Alnylam Medical Monitor, and the CRO Medical Monitor.  The SRC will 
evaluate the available safety data post infusion including but not limited to: AEs, vital 
signs, pulse oximetry, 12-lead ECGs, and available laboratory parameters.  The SRC will 
communicate frequently to ensure that patients are dosed according to the time intervals 
specified in Section 5.6, even as patients are being accrued across multiple centers. 
The options based on SRC discussion (if stopping criteria have not been met) are to: 
• 
Escalate the dose as planned; 
• 
Escalate/decrease the dose to an intermediate level;

• 
Repeat the dose level only in the event of a safety signal (not considered severe) 
that indicates that any further dose escalation may affect the safety of the study 
patients (or to re-evaluate the PK data or to further characterize PD markers); 
• 
Terminate the study. 
The membership of the SRC and reporting structure are defined in the SRC Charter. 
10.4 
Ancillary Research 
Research ancillary to this main protocol may not be performed by individual study sites 
without prior discussion with Alnylam. 
10.5 
Study Record Retention 
Essential documents should be retained for the period of time required by applicable local 
law.  The essential documents include the signed and dated final protocol, signed and 
dated amendments(s), if applicable, signed and dated Curriculum Vitae (CVs) of the 
Investigators, copies of the completed CRFs, signed ICFs, IEC approval and all related 
correspondence, financial agreements, regulatory approval, drug accountability, study 
correspondence, and patient identification codes.  Records will not be destroyed without 
informing Alnylam in writing and giving Alnylam the opportunity to store the records for 
a longer period of time at Alnylam’s expense. 
The International Conference on Harmonization requires that patient identification codes 
be retained for at least 15 years after the completion or discontinuation of the study. 
10.6 
Discontinuation of the Study by Alnylam 
Alnylam reserves the right to discontinue the study for clinical or administrative reasons 
at any time.  If the site does not recruit at a reasonable rate, the study may be 
discontinued.  Should the study be terminated and/or the site closed for whatever reason, 
all documentation and study medication pertaining to the study must be returned to 
Alnylam or its representative, and the Investigators, IEC and Regulatory Authorities will 
be promptly informed of the termination and the reason for the decision.  The 
Investigator should promptly inform the patients and assure appropriate therapy and 
follow-up. 
10.7 
Study Documentation 
Prior to beginning the study, the Investigator will be asked to comply with ICH E6 and 
21 CFR by providing at least the following essential documents:

Amendment 2.1 
Page 97 of 116 
• 
An original signed Investigator agreement page of the protocol and any 
amendments; 
• 
An IEC and Alnylam approved ICF; 
• 
Independent Ethics Committee approval of the protocol, and any amendments; 
• 
Curriculum Vitae for the Investigator signed and dated by the Investigator 
indicating that it is current; 
• 
Financial Disclosure information (if applicable). 
• 
Other documents which the Investigator should provide before study start or 
shortly thereafter include: 
o Curriculum Vitaes for all Sub-Investigators; these should be signed and dated 
by the Sub-investigators indicating that they are current; 
o Financial disclosure information for all Sub-investigators (if applicable); 
o Advertisements for patient recruitment and any other written information to be 
given to patients or legal guardians and IEC approval of any advertisements 
and any other written information; 
o Independent Ethics Committee composition:  If the Investigator or any of the 
Sub-investigators is a member of the IEC, assurance that he/she refrained 
from voting should be provided; 
o Laboratory accreditation and reference ranges for any laboratory values for 
local laboratories. 
10.8 
Confidentiality 
The Investigator must ensure that the patients’ anonymity will be maintained.  On the 
CRFs or other documents submitted to Alnylam, patients should not be identified by their 
names, but by the assigned patient number and initials.  If patient names are included on 
copies of documents submitted to Alnylam, the names (except for initials) will be 
obliterated and the assigned patient number added to the document.  Documents not for 
submission to Alnylam (e.g. signed ICFs) should be maintained by the Investigator in 
strict confidence. 
Following the principles of the Good Clinical Research Practices and the Portuguese 
Protection of Personal Data Directive 95/46/EC, only a patient’s number and initials will 
be used to identify the patient on their study records.  Laboratory samples will be labeled 
with an independent numbering code, and the label will not contain any other personal 
identification information.  The numbering code associated with these labels will be held 
by the study CRO and Alnylam, thereby allowing no unwarranted access to the 
information.  When reporting results for interim safety assessment and at the end of the

study, the code will be shared per standard operating procedures with the responsible 
member of the Biostatistical and Data Management Departments of the CRO.  The 
numbering code will also be held for samples in storage until marketing approval of the 
ALN-TTR02 in the countries where this study was conducted, or until clinical 
development of ALN-TTR02 is halted.  Throughout sample collection, storage (limited, 
staff only access area containing locked sample storage, and limited access sample 
tracking) and processing, the samples will only be handled by appropriate personnel per 
the laboratory’s standard operating procedures. 
The Investigator must treat all of the information related to the study and the compiled 
data as confidential whose use is for the purpose of conducting the study.  Alnylam must 
approve any transfer of information not directly involved in the study. 
10.9 
Publications/Reports 
Following completion of the study, the data may be considered for publication in a 
scientific journal or for reporting at a scientific meeting.  A copy of the manuscript must 
be provided to Alnylam at least 30 days prior to its submission. 
No submission of a manuscript may be made until the results from all of the study centers 
have been received and analyzed by Alnylam, or the study has been terminated at all 
centers.  A separate, individual publication of the results of the study will be delayed until 
initial publication of the results of the multi-center study, or a decision not to publish is 
made.  If an initial draft is not produced within 18 months of completion of the study at 
all centers, or the timeframe for publication is not satisfactory, the Investigator may 
disclose the results after providing a copy of the manuscript to Alnylam 30 days prior to 
submission.

Appendix 1: 
Guidelines for Acute Infusion-Related Reactions 
Mild or Moderate Reaction 
In the event of mild or moderate symptom(s) and/or sign(s) discontinue infusion and treat 
as below: 
• Medication as clinically indicated (e.g., paracetamol, additional H1/H2 blocker, non-
steroidal anti-inflammatory [NSAID], small volumes of physiological saline, and/or 
≤5 L/min oxygen or the reaction is classified as severe); 
• Re-challenge with slower infusion rate (no greater than 3 hour duration) after 
resolution of the reaction; 
• If reaction recurs with re-challenge this patient, this will be a DLT and the patient 
will receive no further study drug. 
Severe Reaction 
In the event of severe sign(s) and symptom(s) discontinue infusion and treat as below:  
• Medication as clinically indicated (e.g., fluids [>1 L saline], oxygen [>5 L/min], 
adrenaline, glucocorticoids, H1/H2 blocker);  
• If a severe acute reaction occurs in any patient, this is a DLT and no more patients 
will be dosed; 
Life-Threatening Reaction 
• If a life-threatening reaction occurs in any patient, this is considered a DLT and no

a 
Early termination procedures: if a patient withdraws prior to Day 56, then the Days 56 and 208 visits should be performed.  If a patient is withdrawn/withdraws after Day 56 
and prior to Day 208, then the Day 208 visit should be performed. 
b 
Interval medical history. 
c 
Focused physical examination (includes head/ears/eyes/nose/throat [HEENT], cardiovascular, respiratory, abdominal, and hepatic assessments).  If the screening physical 
examination was performed within 72 hours of Day 0, then the pre-dose (Day 0) physical examination does not need to be repeated; however, the patient’s weight will be 
obtained. 
d 
Weight measured on Day 0 and Day 21 will be used for calculating first and second dose, respectively. 
e 
Vital signs to include: blood pressure, pulse rate, oral body temperature, and respiratory rate.  Parameters are to be measured in the supine position using an automated 
instrument after the patient has rested comfortably for 10 minutes. 
f 
Serial measures (vital signs and pulse oximetry) are to be measured within 30 minutes pre-dose; at the end of infusion (EOI); and 30 (±5) minutes; 1, 2, and 3 (±15 minutes) 
hours; 6, 12, and 18 (±30 minutes) hours; and 24 (+30 minutes) hours post-infusion. 
g 
Not needed if a normal echocardiogram has been obtained within the past 90 days. 
h 
Serial electrocardiograms (ECGs) will be collected in 3 replicates within 30 minutes pre-dose, EOI, and 30 (±5) minutes, 2 and 4 (±15 minutes) hours, and 24 (+30 minutes) 
hours post-infusion. 
i 
Patients will be hospitalized at the study site for at least 24 hours after the end of infusion of study drug.  Patients may be discharged upon completion of review by the 
Investigator of ECG, sodium, potassium, creatinine, albumin, calcium, glucose, phosphate, and LFTs results obtained at 24-hours post-infusion, if results are deemed not 
clinically significant. Any clinically significant findings must be discussed with the medical monitor to determine whether patient can be discharged and to formulate plans for 
patient follow-up. 
j 
Continuous cardiac monitoring will be performed via telemetry starting no later than 30 minutes prior to dosing and continuing through 24 hours (+1 hour) post-dose. 
k 
Day 0 pre-dose only, not performed on Day 21. 
l 
Serologies include hepatitis B surface antibody (HbsAb), hepatitis B surface antigen (HbsAg), and anti–hepatitis C virus antibody (anti-HCV Ab). 
m 
If the parameter was assessed and meets eligibility requirements within 72 hours of Days 0 and 21, then it does not need to be repeated pre-dose (Days 0 and 21, respectively). 
n 
Liver function tests include aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase, and bilirubin (total and direct). 
o 
Coagulation studies include prothrombin time (PT), activated partial thromboplastin time (aPTT), and international normalized ratio (INR). 
p 
Lipid panel (non-fasting) includes total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL), and triglycerides 
will be collected on Day 0 only. 
q 
Pre-dose samples for TTR protein, vitamin A, and RBP measurements will be drawn immediately (within 10 minutes) prior to the premedications and immediately prior to 
dosing. 
r 
A patient will be followed approximately every 2 weeks after Day 56 if their TTR level continues to recover but is not found to have returned to within at least 80% of the 
baseline value.  If this occurs, the patient will be followed and discussed at each SRC meeting until the TTR level returns to within at least 80% of the baseline value. 
s 
Thyroid function tests include thyroid stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3). 
t 
A blood sample will be collected for the assessment of complement Bb immediately (within 10 minutes) pre-dose, and 30 (±5) minutes, and 2 and 24 hours (±120 minutes) 
post infusion.  If the patient experiences an infusion reaction, a blood sample for analysis of complement factors should be obtained within 1 hour of the start of the reaction. 
u 
A blood sample for the assessment of tryptase and C3a is to be collected only in the event of an acute infusion reaction: at time of event or as soon as possible after onset, 
1 hour, and 24 hours after the event.

Premedications include dexamethasone (8 mg, or equivalent), paracetamol (500 mg, or equivalent), H2 blocker (e.g. 150 mg ranitidine or 20 mg famotidine, or equivalent 
other H2 blocker dose), and H1 blocker (10 mg cetirizine, 25 mg hydroxyzine, fexofenadine or equivalent may be substituted) will be self-administered per os (PO) the 
evening before study drug administration.  Thirty to 60 minutes prior to the start of study drug infusion, dexamethasone (20 mg PO, or equivalent), paracetamol (500 mg PO, 
or equivalent), an H2 blocker (PO), and an H1 blocker (PO) will be administered by study site personnel.  Patients enrolled in an optional cohort evaluating the use of an 
alternative premedication regimen, as agreed upon by the SRC, will receive the following medications at least 60 minutes prior to the start of infusion of ALN-TTR02:  
dexamethasone (10 mg IV, or equivalent), paracetamol (PO 500 mg; or equivalent), IV H2 blocker (e.g. ranitidine 50 mg, famotidine 20 mg, or equivalent other H2 blocker 
dose), and IV H1 blocker (e.g., diphenhydramine 50 mg or equivalent; hydroxyzine or fexofenadine 25 mg PO or cetirizine 10 mg PO may be substituted for any patient who 
does not tolerate IV diphenhydramine or other IV H1 blockers).  These patients will not receive any premedications the evening prior to ALN-TTR02 dosing. 
w 
Site personnel are to call patients the day before dosing to remind them to take premedications that evening (the day before dosing).  This reminder will not be needed for 
patients enrolled in optional cohorts evaluating the alternative premedication regimen. 
x 
The infusion site will be assessed for any localized reaction pre-dose, during infusion, and for 30 minutes after the infusion. 
y 
A blood sample for the assessment of cytokines and C-reactive protein (CRP) will be collected immediately (within 10 minutes) pre-dose, and 2 (±15 minutes), 6 
(±15 minutes), and 24 hours (±120 minutes) post infusion.  If the patient experiences an infusion reaction, a blood sample for analysis of cytokines should be obtained within 
1 hour of the start of the reaction. 
z 
For each dose, plasma PK samples (siRNA and lipids) will be collected pre-dose (within 1 hour of planned dosing start), EOI, and then 5, 10, and 30 minutes, and 1, 2, 4, 6, 
24 and 48 hours post infusion.  Samples will also be collected on Days 7, 14, 28, 35, 42, 49, 56, 112, and 208.  Plasma PK on Day 0 at EOI and then 2 hours post-infusion will 
be analyzed for both free and encapsulated siRNA for cohort 3 and onward, including any optional cohorts.  For each post dose PK blood draw, the following sampling 
windows are allowed: ±1 minute for the 5- and 10-minute draws; ±2 minutes for the 30-minute draws; ±5 minutes for the 1-, 2-, 4-, and 6-hour draws; and ±120 minutes for 
the 24- and 48-hour draws. 
aa 
For each dose, urine PK samples will be collected pre-dose (within 1 hour of planned dosing start), and from 0-6 hours post-infusion (pooled). Samples will also be collected 
on Days 7, 14, 28, 35, 42, 49, 56, 112, and 208.

WORLD MEDICAL ASSOCIATION DECLARATION OF HELSINKI 
Ethical Principles for Medical Research Involving Human Patients 
Recommendations guiding physicians in biomedical research involving human patients 
Adopted by the 18th WMA General Assembly Helsinki, Finland, June 1964 and amended by the: 
29th WMA General Assembly, Tokyo, Japan (October 1975)  
35th WMA General Assembly, Venice, Italy (October 1983) 
41st WMA General Assembly, Hong Kong (September 1989)

59th WMA General Assembly, Seoul, October 2008 
INTRODUCTION  
1. The World Medical Association (WMA) has developed the Declaration of 
Helsinki as a statement of ethical principles for medical research involving human 
patients, including research on identifiable human material and data. The 
Declaration is intended to be read as a whole and each of its constituent 
paragraphs should not be applied without consideration of all other relevant 
paragraphs. 
2. Although the Declaration is addressed primarily to physicians, the WMA 
encourages other participants in medical research involving human patients to 
adopt these principles. 
3. It is the duty of the physician to promote and safeguard the health of patients, 
including those who are involved in medical research. The physician's knowledge 
and conscience are dedicated to the fulfillment of this duty. 
4. The Declaration of Geneva of the WMA binds the physician with the words, "The 
health of my patient will be my first consideration," and the International Code of 
Medical Ethics declares that, "A physician shall act in the patient's best interest 
when providing medical care." 
5. Medical progress is based on research that ultimately must include studies 
involving human patients. Populations that are underrepresented in medical 
research should be provided appropriate access to participation in research. 
6. In medical research involving human patients, the well-being of the individual 
research patient must take precedence over all other interests. 
7. The primary purpose of medical research involving human patients is to 
understand the causes, development and effects of diseases and improve 
preventive, diagnostic and therapeutic interventions (methods, procedures and 
treatments). Even the best current interventions must be evaluated continually 
through research for their safety, effectiveness, efficiency, accessibility and 
quality. 
8. In medical practice and in medical research, most interventions involve risks and 
burdens.

9. Medical research is patient to ethical standards that promote respect for all human 
patients and protect their health and rights. Some research populations are 
particularly vulnerable and need special protection. These include those who 
cannot give or refuse consent for themselves and those who may be vulnerable to 
coercion or undue influence. 
10. Physicians should consider the ethical, legal and regulatory norms and standards 
for research involving human patients in their own countries as well as applicable 
international norms and standards. No national or international ethical, legal or 
regulatory requirement should reduce or eliminate any of the protections for 
research patients set forth in this Declaration. 
BASIC PRINCIPLES FOR ALL MEDICAL RESEARCH  
11. It is the duty of physicians who participate in medical research to protect the life, 
health, dignity, integrity, right to self-determination, privacy, and confidentiality 
of personal information of research patients. 
12. Medical research involving human patients must conform to generally accepted 
scientific principles, be based on a thorough knowledge of the scientific literature, 
other relevant sources of information, and adequate laboratory and, as 
appropriate, animal experimentation. The welfare of animals used for research 
must be respected.  
13. Appropriate caution must be exercised in the conduct of medical research that 
may harm the environment. 
14. The design and performance of each research study involving human patients 
must be clearly described in a research protocol. The protocol should contain a 
statement of the ethical considerations involved and should indicate how the 
principles in this Declaration have been addressed. The protocol should include 
information regarding funding, sponsors, institutional affiliations, other potential 
conflicts of interest, incentives for patients and provisions for treating and/or 
compensating patients who are harmed as a consequence of participation in the 
research study. The protocol should describe arrangements for post-study access 
by study patients to interventions identified as beneficial in the study or access to 
other appropriate care or benefits. 
15. The research protocol must be submitted for consideration, comment, guidance 
and approval to a research ethics committee before the study begins. This 
committee must be independent of the researcher, the sponsor and any other 
undue influence. It must take into consideration the laws and regulations of the 
country or countries in which the research is to be performed as well as applicable 
international norms and standards but these must not be allowed to reduce or 
eliminate any of the protections for research patients set forth in this Declaration. 
The committee must have the right to monitor ongoing studies. The researcher 
must provide monitoring information to the committee, especially information 
about any serious adverse events. No change to the protocol may be made without 
consideration and approval by the committee. 
16. Medical research involving human patients must be conducted only by individuals 
with the appropriate scientific training and qualifications. Research on patients or 
healthy volunteers requires the supervision of a competent and appropriately 
113

qualified physician or other health care professional. The responsibility for the 
protection of research patients must always rest with the physician or other health 
care professional and never the research patients, even though they have given 
consent. 
17. Medical research involving a disadvantaged or vulnerable population or 
community is only justified if the research is responsive to the health needs and 
priorities of this population or community and if there is a reasonable likelihood 
that this population or community stands to benefit from the results of the 
research. 
18. Every medical research study involving human patients must be preceded by 
careful assessment of predictable risks and burdens to the individuals and 
communities involved in the research in comparison with foreseeable benefits to 
them and to other individuals or communities affected by the condition under 
investigation. 
19. Every clinical trial must be registered in a publicly accessible database before 
recruitment of the first patient. 
20. Physicians may not participate in a research study involving human patients 
unless they are confident that the risks involved have been adequately assessed 
and can be satisfactorily managed. Physicians must immediately stop a study 
when the risks are found to outweigh the potential benefits or when there is 
conclusive proof of positive and beneficial results. 
21. Medical research involving human patients may only be conducted if the 
importance of the objective outweighs the inherent risks and burdens to the 
research patients. 
22. Participation by competent individuals as patients in medical research must be 
voluntary. Although it may be appropriate to consult family members or 
community leaders, no competent individual may be enrolled in a research study 
unless he or she freely agrees. 
23. Every precaution must be taken to protect the privacy of research patients and the 
confidentiality of their personal information and to minimize the impact of the 
study on their physical, mental and social integrity. 
24. In medical research involving competent human patients, each potential patient 
must be adequately informed of the aims, methods, sources of funding, any 
possible conflicts of interest, institutional affiliations of the researcher, the 
anticipated benefits and potential risks of the study and the discomfort it may 
entail, and any other relevant aspects of the study. The potential patient must be 
informed of the right to refuse to participate in the study or to withdraw consent to 
participate at any time without reprisal. Special attention should be given to the 
specific information needs of individual potential patients as well as to the 
methods used to deliver the information. After ensuring that the potential patient 
has understood the information, the physician or another appropriately qualified 
individual must then seek the potential patient's freely-given informed consent, 
preferably in writing. If the consent cannot be expressed in writing, the non-
written consent must be formally documented and witnessed.

25. For medical research using identifiable human material or data, physicians must 
normally seek consent for the collection, analysis, storage and/or reuse. There 
may be situations where consent would be impossible or impractical to obtain for 
such research or would pose a threat to the validity of the research. In such 
situations the research may be done only after consideration and approval of a 
research ethics committee. 
26. When seeking informed consent for participation in a research study the physician 
should be particularly cautious if the potential patient is in a dependent 
relationship with the physician or may consent under duress. In such situations the 
informed consent should be sought by an appropriately qualified individual who 
is completely independent of this relationship. 
27. For a potential research patient who is incompetent, the physician must seek 
informed consent from the legally authorized representative. These individuals 
must not be included in a research study that has no likelihood of benefit for them 
unless it is intended to promote the health of the population represented by the 
potential patient, the research cannot instead be performed with competent 
persons, and the research entails only minimal risk and minimal burden. 
28. When a potential research patient who is deemed incompetent is able to give 
assent to decisions about participation in research, the physician must seek that 
assent in addition to the consent of the legally authorized representative. The 
potential patient's dissent should be respected. 
29. Research involving patients who are physically or mentally incapable of giving 
consent, for example, unconscious patients, may be done only if the physical or 
mental condition that prevents giving informed consent is a necessary 
characteristic of the research population. In such circumstances the physician 
should seek informed consent from the legally authorized representative. If no 
such representative is available and if the research cannot be delayed, the study 
may proceed without informed consent provided that the specific reasons for 
involving patients with a condition that renders them unable to give informed 
consent have been stated in the research protocol and the study has been approved 
by a research ethics committee. Consent to remain in the research should be 
obtained as soon as possible from the patient or a legally authorized 
representative. 
30. Authors, editors and publishers all have ethical obligations with regard to the 
publication of the results of research. Authors have a duty to make publicly 
available the results of their research on human patients and are accountable for 
the completeness and accuracy of their reports. They should adhere to accepted 
guidelines for ethical reporting. Negative and inconclusive as well as positive 
results should be published or otherwise made publicly available. Sources of 
funding, institutional affiliations and conflicts of interest should be declared in the 
publication. Reports of research not in accordance with the principles of this 
Declaration should not be accepted for publication.

ADDITIONAL PRINCIPLES FOR MEDICAL RESEARCH COMBINED WITH 
MEDICAL CARE 
31. The physician may combine medical research with medical care only to the extent 
that the research is justified by its potential preventive, diagnostic or therapeutic 
value and if the physician has good reason to believe that participation in the 
research study will not adversely affect the health of the patients who serve as 
research patients. 
32. The benefits, risks, burdens and effectiveness of a new intervention must be tested 
against those of the best current proven intervention, except in the following 
circumstances: 
• 
The use of placebo, or no treatment, is acceptable in studies where no current 
proven intervention exists; or  
• 
Where for compelling and scientifically sound methodological reasons the use of 
placebo is necessary to determine the efficacy or safety of an intervention and the 
patients who receive placebo or no treatment will not be patient to any risk of 
serious or irreversible harm. Extreme care must be taken to avoid abuse of this 
option. 
33. At the conclusion of the study, patients entered into the study are entitled to be 
informed about the outcome of the study and to share any benefits that result from 
it, for example, access to interventions identified as beneficial in the study or to 
other appropriate care or benefits. 
34. The physician must fully inform the patient which aspects of the care are related 
to the research. The refusal of a patient to participate in a study or the patient's 
decision to withdraw from the study must never interfere with the patient-
physician relationship. 
35. In the treatment of a patient, where proven interventions do not exist or have been 
ineffective, the physician, after seeking expert advice, with informed consent 
from the patient or a legally authorized representative, may use an unproven 
intervention if in the physician's judgment it offers hope of saving life, re-
establishing health or alleviating suffering.  Where possible, this intervention 
should be made the object of research, designed to evaluate its safety and 
efficacy.  In all cases, new information should be recorded and, where 
appropriate, made publicly available.

Other changes from Amendment 1.1 to Amendment 2.1 include: 
• Increased the number of optional cohorts from 3 to 5 to allow for the evaluation 
of once every 3 weeks dosing interval as well as an alternative premedication 
regimen and slower infusion rate.   
• Added an additional schedule of assessments for optional cohorts administered 
ALN-TTR02 once every 3 weeks (refer to Appendix 4). 
• The dosing regimen in the first optional cohort will be once every 4 weeks; in the 
remaining 4 optional cohorts the dosing regimen will be once every 3 or 4 weeks.  
The decision on dosing every 3 or 4 weeks will be made by the SRC based on 
safety.  
• The alternative premedication regimen and infusion rate (detailed in Table 1) will 
be evaluated in up to 3 optional cohorts once the safety of the original 
premedication regimen and infusion rate is further established in the first 
2 optional cohorts.   
• Section 1.3 (Summary of Clinical Data with siRNA-LNPs) of the protocol has 
been simplified and primarily cross-references the IB, Edition 3, which contains 
the updated clinical information. 
• Removed the Principal Investigators’ contact information from the protocol itself.  
This information is included in the Study Procedures Manual. 
• Made minor editorial changes (e.g., corrections of typographical, grammatical, 
and spelling errors as well as formatting changes and changes for consistency); 
these changes are not listed individually.

The oOptional cohort(s) would be included to further 
confirm the safety and/or pharmacodynamic (PD) 
effect of previously evaluated dose levels, which may 
include evaluation of the original dosing regimen 
(once every 4 weeks), an alternative dosing regimen 
(once every 3 weeks), and/or an alternative 
premedication regimen and infusion rate.  The 
dosing regimen for the first optional cohort will be 
once every 4 weeks, and the dosing regimen for the 
remaining 4 optional cohorts will be once every 3 or 
4 weeks.  It is anticipated that the first 2 optional 
cohorts will use the original premedication regimen, 
and the remaining 3 optional cohorts may be used to 
explore the alternative premedication regimen and 
infusion rate.   
The SRC will review all available safety data and

Added language to allow an open-label extension 
study. 
An open-label extension study at the recommended 
Phase 3 dose and regimen (as derived from Study 
ALN-TTR02-002) is planned, which will enable the 
patients who enrolled in Study ALN-TTR02-002 to 
receive additional, long-term dosing and safety 
follow-up.  For some of the patients, this may 
preclude the completion of all of the follow-up 
period assessments of Study ALN-TTR02-002 if 
they are deemed eligible to participate in the 
extension study prior to completion of the full follow 
up through Day 208.  Such patients will be followed 
up for a minimum of 28 days after their last dose in 
the current ALN-TTR02-002 study prior to being 
enrolled in the extension study.  The extension study 
will be implemented only after dose escalation is 
completed in Study ALN-TTR02-002, with post 
second dose follow-up through Day 208 in at least 1 
cohort at the highest dose.

ALN-PCS02-001 is a Phase 1 multi-centre, 
randomized, placebo-controlled, single-blind, single-
ascending dose clinical study to evaluate the safety, 
tolerability, PK, and PD of ALN-PCS02.  The study is 
ongoing in the United Kingdom (EudraCT #2011-
000581-36).  ALN-PCS02 was administered as a single 
60-minute IV infusion to healthy volunteers with 
elevated low density lipoprotein-C (LDL-C; >3 
mmol/L) at the following doses: 15, 45, 90, 150, and 
250 µg/kg (4 patients per dose level; 3 receiving ALN-
PCS02 and 1 receiving placebo).  Patients were pre-
medicated with dexamethasone, H1 and H2 blockers, 
and paracetamol prior to dosing to minimize the risk of 
infusion reaction.  As of December 2011, 24 patients 
(23 males and 1 female) have been enrolled in the 
ALN-PCS02-001 study and 18 patients (17 males and 1 
female) have received ALN-PCS02 in 6 cohorts at 
doses ranging from 15 to 250 µg/kg (including 2 
cohorts dosed at the 250 µg/kg dose).   
No dose-limiting toxicities (DLTs) have been reported 
to date, and no patient has prematurely withdrawn from 
the study due to an adverse event (AE).  There was one 
serious adverse event (SAE; bilateral pulmonary

Rationale 
Two consecutive ALN-TTR02 doses, separated by a 4-
week period, will be administered to patients.  Study 
drug will be administered as a 60-minute IV infusion 
with the following proposed doses for each cohort:  10, 
50, 150, and 300 μg/kg ALN-TTR02.   
Two consecutive ALN-TTR02 doses, separated by a 
4-week period (or a 3-week period in select optional 
cohorts), will be administered to patients.  Study drug 
will be administered as a 60-minute IV infusion with 
the following proposed doses for each of the original 
cohorts:  10, 50, 150, and 300 μg/kg ALN-TTR02.  For 
those patients enrolled in an optional cohort 
evaluating the alternative premedication regimen 
and infusion rate, the study drug will be 
administered IV over approximately 70 minutes. 
 
 
In addition, cumulative safety and tolerability data 
observed in at least 2 patients through at least 96 hours 
post-second dose of the previous cohort will be 
reviewed by the SRC prior to administration of the 
second dose of study drug.  The dose level of ALN-
TTR02 administered to any cohort in study ALN-
TTR02-002 may not be higher than that deemed safe 
and tolerable in the Phase 1 single-dose study of ALN-

confirm the safety and/or pharmacodynamic (PD) 
effect of previously evaluated dose levels, which may 
include evaluation of the original dosing regimen 
(once every 4 weeks), an alternative dosing regimen 
(once every 3 weeks), and/or an alternative 
premedication regimen and infusion rate.  The 
dosing regimen for the first optional cohort will be 
once every 4 weeks, and the dosing regimen for the 
remaining 4 optional cohorts will be once every 3 or 
4 weeks.  It is anticipated that the first 2 optional 
cohorts will use the original premedication regimen, 
and the remaining 3 optional cohorts may be used to 
explore the alternative premedication regimen and 
infusion rate.

with TTR lowering.  A similar pattern of 
TTR/RBP/vitamin A decrease and recovery without 
any impact on safety was observed in all patients on the 
study treated at 1.0 mg/kg who showed a response to 
ALN-TTR01.  As with the PD data with ALN-PCS02, 
these data show 
 
 and show 
predictable reversibility. 
The safety of giving multiple doses of an siRNA-LNP 
has been established with ALN-VSP02, which uses the 
same first generation LNP formulation as ALN-TTR01 
(see Investigator’s Brochure).  In a Phase 1 study 
performed in advanced cancer patients with liver 
involvement, chronic bi-weekly dosing with doses as 
high as 1.0 mg/kg was safe and well-tolerated using the 
same premedication regimen as ALN-TTR01, with no 
significant dose-dependent effect on liver function.  
Three patients with tumor shrinkage or prolonged 
disease stabilization who have received biweekly doses 
at 0.7-1.0 mg/kg for as long as 12-18 months are 
continuing their treatment on an extension study. 
Thus, the nonclinical data with ALN-TTR02 and the 
preliminary clinical data with ALN-PCS02, ALN-
TTR01, and ALN-VSP02 support the proposed early 
phase clinical trials evaluating ascending doses (single 
or multiple) of ALN-TTR02 (studies ALN-TTR02-001

1.5:  Dose Selection and 
Rationale 
Two consecutive ALN-TTR02 doses, separated by a 4-
week period, will be administered to patients.  Study 
drug will be administered as a 60-minute IV infusion 
with the following proposed doses for each cohort:  10, 
50, 150, and 300 μg/kg ALN-TTR02.   
Two consecutive ALN-TTR02 doses, separated by a 
4-week period (or a 3-week period in select optional 
cohorts), will be administered to patients.  Study drug 
will be administered as a 60-minute IV infusion with 
the following proposed doses for each of the original 
cohorts:  10, 50, 150, and 300 μg/kg ALN-TTR02.  For 
those patients enrolled in an optional cohort 
evaluating the alternative premedication regimen 
and infusion rate, the study drug will be 
administered IV over approximately 70 minutes. 
 
 
In addition, cumulative safety and tolerability data 
observed in at least 2 patients through at least 96 hours 
post-second dose of the previous cohort will be 
reviewed by the SRC prior to administration of the 
second dose of study drug.  The dose level of ALN-
TTR02 administered to any cohort in study ALN-
TTR02-002 may not be higher than that deemed safe 
and tolerable in the Phase 1 single-dose study of ALN-
TTR02 (Study ALN-TTR02-001).

A Phase 2, Open-Label, Multi-Dose, Dose Escalation Trial to Evaluate the Safety, 
Tolerability, Pharmacokinetics, and Pharmacodynamics of Intravenous Infusions of ALN-
TTR02 in Patients with TTR Amyloidosis 
Changes included in Amendment 1 to Protocol ALN-TTR02-002, dated 19 June 2012, 
are itemized below and detailed in the pages that follow. 
 Added pertinent information from the ongoing chronic GLP toxicology study in non-
human primates (Study 504265); also, reference is made to the Expedited Safety 
Report addendum dated 7 June 2012 to the IB, which contains the details of the 
nonclinical finding from this study. 
 Made additional references, where relevant, to the Expedited Safety Report 
addendum dated 7 June 2012, which in addition to providing pertinent data from the 
ongoing chronic GLP toxicology study in non-human primates, also includes 
preliminary safety and efficacy updates from the Phase 1 trials of ALN-TTR02 in 
healthy volunteers (ALN-TTR02-001) and ALN-PCS02 in healthy volunteers with 
elevated cholesterol (ALN-PCS02-001).  
 In light of the favorable single-dose safety data that have emerged from the recently 
completed Phase 1 trials of ALN-TTR02 and ALN-PCS02 at doses greater than or 
equal to the top dose on this study (detailed in Expedited Safety Report addendum 
dated 7 June 2012 to the IB), we have removed the requirement that the SRC review 
safety data on all patients within a dose level following first dose prior to any patient 
at that dose level receiving their second dose. 
 Removed the 500 g/kg dose cohort (highest dose) since the ALN-TTR02-001 study 
has completed enrollment and demonstrated adequate pharmacology at the 0.3 mg/kg 
dose. 
 Having removed the top dose, thus reducing the total number of patients in the study 
from 24 to 21.  Instead, the number of optional cohorts has been increased from 3 to 4 
to allow for further evaluation of safety and/or pharmacodynamic effect. 
 Extended the post-dose on-site observation period from 6 hours to 24 hours post-
infusion
 
  
 Added the following additional safety evaluations to further ensure patient safety: 
 Continuous cardiac monitoring (telemetry) to be performed during dosing and for 
24 hours post-dose (from Days 0 to 1 and again from Days 28 to 29).

INFORMATION FROM THE STUDY PROTOCOL 
1.1. 
Introduction and Objectives 
1.1.1. 
Introduction 
Transthyretin (TTR), also known as prealbumin, is a tetramer protein produced predominantly 
by hepatocytes (>95% of TTR is liver-derived), with a small fraction produced in the choroid 
plexus and retina.[1]  The primary physiological role of TTR is to serve as a carrier of retinol 
(also known as vitamin A); it also plays a minor role as a carrier for thyroxine (T4). 
Mutations in the TTR gene can lead to destabilization of the tetrameric protein and 
disassociation of the TTR subunits into dimers and individual monomers.  These misfolded TTR 
monomers (both mutant and wild type [WT]) can then self-assemble into amyloid fibrils.[2]  
The amyloid fibrils are deposited into the extracellular space of various tissues where they form 
amyloid plaques, with the peripheral nervous system, gastrointestinal tract, and heart being 
among the major sites of deposition. 
There are over 100 reported TTR genetic mutations, and phenotypically these result in a 
spectrum of disease which is collectively referred to as TTR-mediated amyloidosis (ATTR).[3]  
There is a range of clinical manifestations of ATTR; the most common manifestations include 
some form of cardiac and/or neurologic involvement (e.g., cardiomyopathy, autonomic 
neuropathy, and sensory and motor neuropathy) that depends, in part, upon the particular TTR 
mutation and the site of amyloid deposition.  Transthyretin amyloidosis is associated with 
severe morbidity and mortality, with a life expectancy limited to approximately 5 to 15 years 
from symptom onset.[4] 
Because the liver is the primary source of mutant TTR, liver transplantation has been used over 
the past 20 years in an attempt to treat ATTR.  However, the procedure is only effective in 
halting or slowing the progression of disease in patients with an early age of onset[5], especially 
for those with the V30M mutation and short disease duration prior to transplant; consequently, 
almost two-thirds of ATTR patients are not transplant-eligible.  Tafamidis, a TTR tetramer 
stabilizer, was approved (November 2011) in the European Union (EU) for the treatment of 
ATTR in adult patients with stage 1 symptomatic polyneuropathy to delay peripheral neurologic 
impairment.[6]  The large majority of ATTR patients do not qualify for either liver 
transplantation or tafamidis.  In these patients, the disease is primarily managed with palliative 
care.

Ribonucleic interference (RNAi) is a naturally occurring cellular mechanism for regulating gene 
expression that is mediated by “small interfering ribonucleic acids” (siRNAs).[7]  Typically, 
synthetic siRNAs are 19 to 23 base pair double-stranded oligonucleotides in a staggered duplex 
with a 2-nucleotide overhang at 1 or both of the 3' ends.  Such siRNAs can be designed to target 
an endogenous or virally-expressed gene.  When introduced into cells, the net effect of an 
RNAi-based pharmacological approach is the binding of the siRNA to its complementary 
messenger ribonucleic acid (mRNA) sequence, cleavage of this target mRNA, and suppression 
of the target protein.[8]  The ability to selectively and potently degrade the mRNA encoding the 
TTR protein using a siRNA offers a potent and specific approach for the treatment of ATTR. 
Alnylam Pharmaceuticals is developing ALN-TTR02 Solution for Injection (hereafter referred 
to as ALN-TTR02), a synthetic investigational RNAi therapeutic comprising a siRNA targeting 
the TTR mRNA formulated in a lipid nanoparticle (LNP) termed AF-011.  The LNP enables 
delivery of the siRNA primarily to the liver upon systemic administration, resulting in the 
down-regulation of hepatic TTR expression and, in turn, reducing serum mutant and WT TTR 
levels.  The proposed indication for ALN-TTR02 is for the treatment of ATTR.  ALN-TTR02 is 
intended for administration as an intravenous (IV) infusion over 1 hour. 
ALN-TTR02, a second generation siRNA LNP formulation termed AF-011, employs the same 
siRNA as ALN-TTR01, which utilizes the first generation LNP (termed stable nucleic acid lipid 
particles [SNALP]).  Both ALN-TTR01 and ALN-TTR02 are intended for the treatment of 
patients with ATTR; the AF-011 formulation, however, has been optimized to be more potent 
such that mRNA and protein reduction effects are observed at significantly lower doses with 
AF-011 than with the SNALP formulation. 
1.1.2. 
Study Objectives 
The primary objective of this study is to evaluate the safety and tolerability of multiple doses of 
ALN-TTR02. 
The secondary objectives of this study are: 
 To characterize the plasma and urine pharmacokinetics (PK) of ALN-TTR02. 
 To assess preliminary evidence of the pharmacodynamic (PD) effect of ALN-TTR02 on 
serum total TTR levels. 
This statistical analysis plan (SAP) is designed to outline the methods to be used in the analysis 
of study data in order to answer the study objective(s).  Populations for analysis, data handling 
rules, statistical methods, and formats for data presentation are provided.  The statistical

analyses and summary tabulations described in this SAP will provide the basis for the results 
sections of the clinical study report (CSR) for this trial.  Pharmacokinetic (PK) and 
pharmacokinetic/pharmacodynamics (PK/PD) analyses will be described in a separate analytical 
plan, will be performed by Alnylam Pharmaceuticals or its designated Contract Research 
Organization (CRO), and presented in a separate report (to be included in the CSR). 
This SAP will also outline any differences in the currently planned analytical objectives relative 
to those planned in the study protocol. 
1.2. 
Study Design 
1.2.1. 
Synopsis of Study Design 
Protocol ALN-TTR02-002 is a multi-national, multi-center, Phase 2, open-label, multi-dose, 
dose escalation study designed to determine the safety, tolerability, PK, and PD of 2 consecutive 
doses (separated by approximately 4 weeks) of ALN-TTR02 in patients with ATTR. 
Patients of any mutant TTR genotype with a biopsy-proven diagnosis of ATTR who exhibit 
documented signs/symptoms of the disease (e.g., sensory, motor, or autonomic neuropathy) that 
are at least mild to moderate in severity will be eligible for the study, provided they have a body 
mass index (BMI) of 17-33 kg/m2, an adequate performance status (Karnofsky performance 
status of 60% or greater), adequate hepatic and renal function, no active infection or 
inflammatory disorder, stable cardiac status, and have not had a liver transplant. 
Two doses of ALN-TTR02 will be given 4 weeks apart to 4 sequential cohorts comprised of 3 
patients each.  The 4 cohorts will receive ascending doses of 10, 50, 150, and 300 μg/kg.  No 
patient will be a member of more than 1 treatment group.  An alternative dosing regimen of 2 
doses of ALN-TTR02 (at a dose previously determined by the Safety Review Committee [SRC] 
to be safe and tolerable) separated by 3 weeks may be evaluated in the optional cohort(s). 
Within each of the cohorts, the first patient will receive their first dose and if the dose is well-
tolerated (per protocol Section 5.7.3, Dose-limiting Toxicity), Patients 2 and 3 will receive their 
first dose at that same dose level no sooner than 48 hours apart, with Patient 2 receiving a dose 
of study drug no sooner than 48 hours after the dosing of Patient 1.  Similar to the first dose, the 
second dose will be administered to patients 4 weeks after the first dose in a sequential manner 
with at least 48 hours separating dosing of each patient.  If after the first dose, ALT and AST are 
>2.5 ×ULN, that patient would not receive their second dose. 
Dose escalation to the next cohort will proceed after the collective safety and tolerability data 
through at least 96 hours post-first dose from the 3 patients in the previous cohort has been

13 
reviewed by the SRC.  If the administered dose is found to be safe and well-tolerated, dosing for 
the next cohort will begin no sooner than 96 hours after Patient 3 has safely received dose 1 
from the previous cohort.  Patients in the cohort would be dosed and reviewed for safety and 
tolerability following the same procedures as used for other cohorts (as stated above). 
For patients on all dose levels other than the starting dose level of 10 g/kg, prior to receiving 
the second dose the SRC will review the cumulative safety and tolerability data of at least 
2 patients from the previous dose level(s) with at least 96 hours of follow-up after receiving a 
second dose of study drug. 
For any dose-limiting toxicity (DLT), accrual to that dose level will stop, all dosing will be 
discontinued, and dose escalation will end, pending further evaluation of all available safety 
data by the SRC (see protocol Section 5.7.4).  The SRC may be convened earlier at the 
discretion of Alnylam if important safety issues arise requiring the attention of the committee 
(e.g., new safety information attained in other ongoing studies with ALN-TTR02). 
The duration of patient participation in this study is approximately 36 weeks.  Patients will be 
screened from -45 to -3 days prior to dose administration.  Eligible patients will undergo further 
pre-treatment assessments (performed on Day 0).  Patients receiving the original premedication 
regimen will receive oral premedication with dexamethasone (or equivalent), paracetamol (or 
equivalent), and H1 and H2 blockers the night before and 30 to 60 minutes prior to each dose of 
ALN-TTR02 to reduce the potential of an infusion-related reaction (IRR) (see protocol 
Section 5.5).  Those patients in an optional cohort evaluating an alternative premedication 
regimen, as agreed upon by the SRC, will receive IV dexamethasone (or equivalent), oral 
paracetamol (or equivalent), and IV H1 and H2 blockers at least 60 minutes prior to ALN-
TTR02 dosing; no premedication will be administered the evening prior to dosing.  On Days 0 
and 28, patients on the 4-week dosing regimen will receive a single dose of ALN-TTR02 
administered as a 60-minute IV infusion (for cohorts with the original premedication regimen 
and infusion rate), or as an approximate 70-minute IV infusion for those patients in an optional 
cohort evaluating the alternative premedication regimen and infusion rate.  The infusion time 
may be extended up to 3 hours in the event of a mild or moderate infusion reaction (study drug 
administration will not be resumed for any patient following a severe infusion reaction).  Details 
on the study drug administration are provided in protocol Section 5.6.  Patients will be 
hospitalized at the study site for at least 24 hours after the end of the study drug infusion.  
Patients may be discharged upon Investigator review of the 24-hour electrocardiogram (ECG), 
liver function tests (LFTs), and a subset of serum chemistries (sodium, potassium, creatinine,

albumin, calcium, glucose, and phosphate), if results are deemed not clinically significant.  
Patients will return to the site for outpatient visits for safety, PK, and PD monitoring up to 
208 days post-dose (see protocol Section 6 for details). 
The SRC will evaluate safety in the study and determine if it remains acceptable to dose escalate 
or administer the second dose to the next dose level per their safety review charter.  To ensure 
timely safety information exchange across the participating study centers, the SRC will be 
comprised of all Principal Investigators (PIs) participating in the study or their designee, the 
Alnylam Medical Monitor, and the CRO Medical Monitor.  The SRC will communicate 
frequently to ensure that patients are dosed according to the time intervals specified in protocol 
Section 5.6, even as patients are being accrued across multiple centers. 
An open-label extension study at the recommended Phase 3 dose and regimen (as determined 
from Study ALN-TTR02-002) is planned, which will enable the patients who enrolled in Study 
ALN-TTR02-002 to receive additional, long-term dosing and safety follow-up.  For some of the 
patients, this may preclude the completion of all of the follow-up period assessments of Study 
ALN-TTR02-002 if they are deemed eligible to participate in the extension study prior to 
completion of the full follow up through Day 208.  Such patients will be followed up for a 
minimum of 28 days after their last dose in the current ALN-TTR02-002 study prior to being 
enrolled in the extension study.  The extension study will be implemented only after dose 
escalation is completed in Study ALN-TTR02-002, with post second dose follow-up through 
Day 208 in at least 1 cohort at the highest dose.

Note: The schedule of assessments for optional cohorts administered ALN-TTR02 once every 3 weeks is provided in Table 1-2. 
a 
Early termination procedures: if a patient withdraws prior to Day 56, then the Days 56 and 208 visits should be performed.  If a patient is withdrawn/withdraws after Day 56 
and prior to Day 208, then the Day 208 visit should be performed. 
b 
Interval medical history. 
c 
Focused physical examination (includes head/ears/eyes/nose/throat [HEENT], cardiovascular, respiratory, abdominal, and hepatic assessments).  If the screening physical 
examination was performed within 72 hours of Day 0, then the pre-dose (Day 0) physical examination does not need to be repeated; however, the patient’s weight will be 
obtained. 
d 
Weight measured on Day 0 and Day 28 will be used for calculating first and second dose, respectively. 
e 
Vital signs to include: blood pressure, pulse rate, oral body temperature, and respiratory rate.  Parameters are to be measured in the supine position using an automated 
instrument after the patient has rested comfortably for 10 minutes. 
f 
Serial measures (vital signs and pulse oximetry) are to be measured within 30 minutes pre-dose; at the end of infusion (EOI); and 30 (±5) minutes; 1, 2, and 3 (±15 minutes) 
hours; 6, 12, and 18 (±30 minutes) hours; and 24 (+30 minutes) hours post-infusion. 
g 
Not needed if a normal echocardiogram has been obtained within the past 90 days. 
h 
Serial electrocardiograms (ECGs) will be collected in 3 replicates within 30 minutes pre-dose, EOI, and 30 (±5) minutes, 2 and 4 (±15 minutes) hours, and 24 (+30 minutes) 
hours post-infusion. 
i 
Patients will be hospitalized at the study site for at least 24 hours after the end of infusion of study drug.  Patients may be discharged upon completion of review by the 
Investigator of ECG, sodium, potassium, creatinine, albumin, calcium, glucose, phosphate, and LFTs results obtained at 24-hours post-infusion, if results are deemed not 
clinically significant.  Any clinically significant findings must be discussed with the medical monitor to determine whether patient can be discharged and to formulate plans 
for patient follow-up. 
j 
Continuous cardiac monitoring will be performed via telemetry starting no later than 30 minutes prior to dosing and continuing through 24 hours (+1 hour) post-dose. 
k 
Day 0 pre-dose only, not performed on Day 28. 
l 
Serologies include hepatitis B surface antibody (HbsAb), hepatitis B surface antigen (HbsAg), and anti–hepatitis C virus antibody (anti-HCV Ab). 
m 
If the parameter was assessed and meets eligibility requirements within 72 hours of Days 0 and 28, then it does not need to be repeated pre-dose (Days 0 and 28, respectively). 
n 
Liver function tests include aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase, and bilirubin (total and direct). 
o 
Coagulation studies include prothrombin time (PT), activated partial thromboplastin time (aPTT), and international normalized ratio (INR). 
p 
Lipid panel (non-fasting) includes total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL), and triglycerides 
will be collected on Day 0 only. 
q 
Pre-dose samples for TTR protein, vitamin A, and RBP measurements will be drawn immediately (within 10 minutes) prior to the premedications and immediately prior to 
dosing. 
r 
A patient will be followed approximately every 2 weeks after Day 56 if their TTR level continues to recover but is not found to have returned to within at least 80% of the 
baseline value.  If this occurs, the patient will be followed and discussed at each SRC meeting until the TTR level returns to within at least 80% of the baseline value. 
s 
Thyroid function tests include thyroid stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3). 
t 
A blood sample will be collected for the assessment of complement Bb immediately (within 10 minutes) pre-dose, and 30 (±5) minutes, and 2 (± 15 minutes) and 24 hours 
(±120 minutes) post infusion.  If the patient experiences an infusion reaction, a blood sample for analysis of complement factors should be obtained within 1 hour of the start 
of the reaction.

u 
A blood sample for the assessment of tryptase and C3a is to be collected only in the event of an acute infusion reaction: at time of event or as soon as possible after onset, 
1 hour, and 24 hours after the event. 
v 
Premedications include dexamethasone (8 mg, or equivalent), paracetamol (500 mg, or equivalent), H2 blocker (e.g., 150 mg ranitidine or 20 mg famotidine, or equivalent 
other H2 blocker dose), and H1 blocker (10 mg cetirizine, 25 mg hydroxyzine, fexofenadine or equivalent may be substituted) will be self-administered per os (PO) the 
evening before study drug administration.  Thirty to 60 minutes prior to the start of study drug infusion, dexamethasone (20 mg PO, or equivalent), paracetamol (500 mg PO, 
or equivalent), an H2 blocker (PO), and an H1 blocker (PO) will be administered by study site personnel.  Patients enrolled in an optional cohort evaluating the use of an 
alternative premedication regimen, as agreed upon by the SRC, will receive the following medications at least 60 minutes prior to the start of infusion of ALN-TTR02:  
dexamethasone (10 mg IV, or equivalent), paracetamol (PO 500 mg; or equivalent), IV H2 blocker (e.g. ranitidine 50 mg, famotidine 20 mg, or equivalent other H2 blocker 
dose), and IV H1 blocker (e.g., diphenhydramine 50 mg or equivalent; hydroxyzine or fexofenadine 25 mg PO or cetirizine 10 mg PO may be substituted for any patient who 
does not tolerate IV diphenhydramine or other IV H1 blockers).  These patients will not receive any premedications the evening prior to ALN-TTR02 dosing. 
w 
Site personnel are to call patients the day before dosing to remind them to take premedications that evening (the day before dosing).  This reminder will not be needed for 
patients enrolled in optional cohorts evaluating the alternative premedication regimen. 
x 
The infusion site will be assessed for any localized reaction pre-dose, during infusion, and for 30 minutes after the infusion. 
y 
A blood sample for the assessment of cytokines and C-reactive protein (CRP) will be collected immediately (within 10 minutes) pre-dose, and 2 (±15 minutes), 6 (±15 
minutes), and 24 hours (±120 minutes) post infusion.  If the patient experiences an infusion reaction, a blood sample for analysis of cytokines should be obtained within 
1 hour of the start of the reaction. 
z 
For each dose, plasma PK samples (siRNA and lipids) will be collected pre-dose (within 1 hour of planned dosing start), EOI, and then 5, 10, and 30 minutes, and 1, 2, 4, 6, 
24 and 48 hours post infusion.  Samples will also be collected on Days 7, 14, 21, 35, 42, 49, 56, 112, and 208.  Plasma PK on Day 0 at EOI and then 2 hours post-infusion will 
be analyzed for both free and encapsulated siRNA for cohort 3 and onward, including any optional cohorts.  For each post dose PK blood draw, the following sampling 
windows are allowed: ±1 minute for the 5- and 10-minute draws; ±2 minutes for the 30-minute draws; ±5 minutes for the 1-, 2-, 4-, and 6-hour draws; and ±120 minutes for 
the 24- and 48-hour draws. 
aa 
For each dose, urine PK samples will be collected pre-dose (within 1 hour of planned dosing start), and from 0-6 hours post-infusion (pooled).  Samples will also be collected 
on Days 7, 14, 21, 35, 42, 49, 56, 112, and 208. 
bb Pre-dose samples should be collected prior to infusion, but after premedications have been administered.

A patient will be followed approximately every 2 weeks after Day 56 if their TTR level continues to recover but is not found to have returned to within at least 80% of the 
baseline value.  If this occurs, the patient will be followed and discussed at each SRC meeting until the TTR level returns to within at least 80% of the baseline value. 
s 
Thyroid function tests include thyroid stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3). 
t 
A blood sample will be collected for the assessment of complement Bb immediately (within 10 minutes) pre-dose, and 30 (±5) minutes, and 2 and 24 hours (±120 minutes) 
post infusion.  If the patient experiences an infusion reaction, a blood sample for analysis of complement factors should be obtained within 1 hour of the start of the reaction.

u 
A blood sample for the assessment of tryptase and C3a is to be collected only in the event of an acute infusion reaction: at time of event or as soon as possible after onset, 
1 hour, and 24 hours after the event. 
v 
Premedications include dexamethasone (8 mg, or equivalent), paracetamol (500 mg, or equivalent), H2 blocker (e.g. 150 mg ranitidine or 20 mg famotidine, or equivalent 
other H2 blocker dose), and H1 blocker (10 mg cetirizine, 25 mg hydroxyzine, fexofenadine or equivalent may be substituted) will be self-administered per os (PO) the 
evening before study drug administration.  Thirty to 60 minutes prior to the start of study drug infusion, dexamethasone (20 mg PO, or equivalent), paracetamol (500 mg PO, 
or equivalent), an H2 blocker (PO), and an H1 blocker (PO) will be administered by study site personnel.  Patients enrolled in an optional cohort evaluating the use of an 
alternative premedication regimen, as agreed upon by the SRC, will receive the following medications at least 60 minutes prior to the start of infusion of ALN-TTR02:  
dexamethasone (10 mg IV, or equivalent), paracetamol (PO 500 mg; or equivalent), IV H2 blocker (e.g. ranitidine 50 mg, famotidine 20 mg, or equivalent other H2 blocker 
dose), and IV H1 blocker (e.g., diphenhydramine 50 mg or equivalent; hydroxyzine or fexofenadine 25 mg PO or cetirizine 10 mg PO may be substituted for any patient who 
does not tolerate IV diphenhydramine or other IV H1 blockers).  These patients will not receive any premedications the evening prior to ALN-TTR02 dosing. 
w 
Site personnel are to call patients the day before dosing to remind them to take premedications that evening (the day before dosing).  This reminder will not be needed for 
patients enrolled in optional cohorts evaluating the alternative premedication regimen. 
x 
The infusion site will be assessed for any localized reaction pre-dose, during infusion, and for 30 minutes after the infusion. 
y 
A blood sample for the assessment of cytokines and C-reactive protein (CRP) will be collected immediately (within 10 minutes) pre-dose, and 2 (±15 minutes), 6 
(±15 minutes), and 24 hours (±120 minutes) post infusion.  If the patient experiences an infusion reaction, a blood sample for analysis of cytokines should be obtained within 
1 hour of the start of the reaction. 
z 
For each dose, plasma PK samples (siRNA and lipids) will be collected pre-dose (within 1 hour of planned dosing start), EOI, and then 5, 10, and 30 minutes, and 1, 2, 4, 6, 
24 and 48 hours post infusion.  Samples will also be collected on Days 7, 14, 28, 35, 42, 49, 56, 112, and 208.  Plasma PK on Day 0 at EOI and then 2 hours post-infusion will 
be analyzed for both free and encapsulated siRNA for cohort 3 and onward, including any optional cohorts.  For each post dose PK blood draw, the following sampling 
windows are allowed: ±1 minute for the 5- and 10-minute draws; ±2 minutes for the 30-minute draws; ±5 minutes for the 1-, 2-, 4-, and 6-hour draws; and ±120 minutes for 
the 24- and 48-hour draws. 
aa 
For each dose, urine PK samples will be collected pre-dose (within 1 hour of planned dosing start), and from 0-6 hours post-infusion (pooled).  Samples will also be collected 
on Days 7, 14, 28, 35, 42, 49, 56, 112, and 208. 
bb Pre-dose samples should be collected prior to infusion, but after premedications have been administered.

Pharmacodynamic and Safety Parameters 
1.2.5.1. 
Pharmacodynamic Parameters 
The PD evaluation will include assessment of effects of ALN-TTR02 on serum total TTR 
levels.  Exploratory PD effects of ALN-TTR02 will be evaluated by: 
 Serial measurement of circulating mutant and wild type TTR levels. 
 Serial measurement of serum TTR mRNA levels. 
 Serial measurement of circulating vitamin A and retinol binding protein (RBP) levels. 
1.2.5.2. 
Safety Parameters 
Safety monitoring will include assessment of adverse events (AEs), 12-lead ECGs, cardiac 
monitoring (telemetry), arterial oxygen saturation (SaO2) using pulse oximetry, vital signs 
(blood pressure, pulse rate, oral body temperature, and respiratory rate), clinical laboratory 
safety tests (hematology, serum chemistry, LFTs, thyroid function parameters, serology, 
coagulation parameters, urinalysis, cytokines, c-reactive protein [CRP], and complement 
factors), and physical examinations.  Patients will be closely monitored for both acute and 
delayed IRRs.  All IRRs will be recorded as AEs. 
The safety of ALN-TTR02 will be evaluated by: 
 The proportion of subjects experiencing AEs, serious adverse events (SAEs), DLTs, 
infusion-related AEs, and AEs leading to study drug discontinuation. 
 Infusion tolerability, as assessed by serial ECGs, measurement of SaO2 by pulse 
oximetry, and blood pressure. 
 Change from baseline in clinical laboratory test results, including hematology, serum 
chemistries, LFTs, and coagulation parameters. 
 Change from baseline in measures of thyroid function (thyroid stimulating hormone 
[TSH], T4, and triiodothyronine [T3]. 
 Change from baseline in CRP, cytokines, and complement. 
 Vital sign measurements. 
 Physical examination findings.

SUBJECT POPULATION 
2.1. 
Population Definitions 
The following patient populations (i.e., analysis sets) may be evaluated and used for 
presentation of the data: 
 Intent-to-Treat (ITT) Analysis Set:  All patients who were enrolled and received study 
treatment. 
 Per-Protocol (PP) Analysis Set:  All patients in the ITT analysis set who had no major 
protocol violations. 
 Pharmacokinetic (PK) Analysis Set:  All patients in the ITT analysis set who have 
adequate data to determine a full PK profile. 
The ITT analysis set is the primary population for the analysis of PD and safety parameters.  A 
secondary analysis of PD parameters will be performed for the PP analysis set.  The PK analysis 
set is the primary population for the analysis of PK parameters. 
2.2. 
Protocol Violations 
At the discretion of the Sponsor, major protocol violations, as determined by a review of the 
data prior to unblinding of the study results and the conduct of statistical analyses, may result in 
the removal of a subject’s data from the PP analysis set.  Medpace will be responsible for 
producing the final protocol violation file (formatted as a Microsoft Excel file), which will be 
reviewed by Veristat and Alnylam; this file will include a description of the protocol violation 
and clearly identify whether or not this violation warrants exclusion from the PP analysis set.  
This file will be finalized prior to hard database lock. 
All protocol violations will be presented in a data listing.

3. 
GENERAL STATISTICAL METHODS 
3.1. 
Sample Size Justification 
Based on the planned dose escalation scheme, up to 27 patients are expected to be enrolled.  
Three patients are to be enrolled at each of 4 planned dose levels.  An additional 5 cohorts of 3 
patients may be enrolled onto 1 or more of these specified dose levels to further evaluate safety 
and tolerability or PD effects.  The sample size was chosen based on previous experience in 
Phase 2 studies and was not based on power calculations. 
3.2. 
General Methods 
All data listings that contain an evaluation date will contain a relative study day.  Pre-treatment 
and on-treatment study days are numbered relative to the day of study medication dosing, which 
is designated as Day 0.  For example, the day prior to study medication will be Day -1 and the 
day after study medication will be Day 1. 
All output will be incorporated into Microsoft Word or Excel files, or Adobe Acrobat PDF files, 
sorted and labeled according to the International Conference on Harmonisation (ICH) 
recommendations, and formatted to the appropriate page size(s). 
Tabulations will be produced for appropriate demographic, baseline, efficacy, and safety 
parameters.  For categorical variables, summary tabulations of the number and percentage of 
subjects within each category (with a category for missing data) of the parameter will be 
presented.  For continuous variables, the number of subjects, mean, median, standard deviation 
(SD), minimum, and maximum values will be presented. 
All data will be presented in by-subject data listings. 
As this is a Phase 2 dose-escalation trial, formal statistical hypothesis testing will not be 
performed.  Although exploratory confidence intervals (CIs) will be presented as described 
below, no formal statistical conclusions will be made based on these estimates. 
Subjects will be analyzed in the cohort to which they were originally assigned.  Data will be 
tabulated for each dose group (i.e., dose level, regimen, and pre-medication regimen). 
Laboratory data collected and recorded as below the limit of detection will be set equal to the 
lower limit of detection for the calculation of summary statistics.

CONFIDENTIAL 
26 
3.3. 
Computing Environment 
All descriptive statistical analyses will be performed using SAS statistical software version 9.3 
or higher, unless otherwise noted.  Adverse events will be coded for summarization using the 
Medical Dictionary for Regulatory Activities (MedDRA® version 15.0).  Concomitant 
medications will be coded using the World Health Organization (WHO) Drug Dictionary 
(March 2012 version). 
3.4. 
Baseline Definitions 
Unless noted otherwise, baseline will be defined as the Day 0 pre-dose value when non-missing, 
otherwise the latest value from amongst any screening values will be used (i.e., the 
measurement closest to and prior to dosing will be considered baseline).  For PD parameters 
(TTR, RBP, Vitamin A), baseline will be defined as the average of all pre-dose values (i.e., 
Screening and Day 0 pre-dose values). 
3.5. 
Methods of Pooling Data 
Data will be summarized separately for each dose group (i.e., dose level and regimen).  Data 
from expansion cohorts that are dosed at the same level and regimen as a previous cohort will be 
pooled with the previous cohort for presentation by dose group.  In addition, safety data will be 
presented overall. 
Data will be tabulated separately for dose groups dosed 4 weeks apart and dose groups dosed 3 
weeks apart, if applicable. 
3.6. 
Adjustments for Covariates 
No formal statistical analyses that adjust for possible covariate effects are planned. 
3.7. 
Multiple Comparisons/Multiplicity 
Multiplicity is not of concern for this Phase 2 study with a descriptive interpretation. 
3.8. 
Subpopulations 
Summaries of serial TTR will be presented by genotype (V30M versus other) and use of TTR 
stabilizer (tafamidis or diflunisal use versus none). 
3.9. 
Withdrawals, Dropouts, Loss to Follow-up 
Subjects who voluntarily withdraw are termed dropouts.  Dropouts may be replaced following 
discussion with the Investigator and Sponsor.

Subjects who are withdrawn due to AEs during infusion of the ALN-TTR02 will not be 
replaced. 
If a subject is withdrawn/withdraws, the discharge procedures should be performed and an early 
termination (ET) visit scheduled as follows: 
 If a subject is withdrawn/withdraws prior to Day 56, then the Day 56 assessments should 
be completed; 
 If a subject is withdrawn/withdraws after Day 56 and prior to Day 208, then the Day 208 
assessments should be completed. 
Data collected at an ET visit will be included in Day 56 or Day 208 tabular summaries.  That is, 
the Day 28 summary will include actual observed values from Day 56 along with data collected 
from any ET visits prior to Day 56.  Similarly, the Day 208 summary will include data from 
subjects completing the study, along with any data collected at ET visits between Day 56 and 
Day 208. 
3.10. 
Missing, Unused, and Spurious Data 
In general, there will be no substitutions made to accommodate missing data points.  All data 
recorded on the case report form (CRF) will be included in data listings that will accompany the 
CSR.  Data collected at multiple time points throughout the study will be presented in 
chronological order in the data listings according to assessment date/time. 
Handling of partial dates for determining whether an AE is treatment-emergent is discussed in 
Section 4.5.2.  Handling of partial dates for determining concomitant medication is discussed in 
Section 4.5.6. 
3.11. 
Visit Windows 
It is expected that all visits will occur according to the protocol schedule of assessments.  All 
data will be tabulated per the evaluation visit as recorded on the CRF even if the assessment is 
outside of the window for that study visit.  In data listings, the study day relative to Day 0 (day 
of first dose) will be presented. 
Unscheduled visits will be included in data listings, but no assignment to a study visit will be 
made for the purpose of summary tabulations.

STUDY ANALYSES 
4.1. 
Subject Disposition 
Subject disposition will be tabulated and include the number enrolled, the number dosed, the 
number in each subject population for analysis, the number who completed the study (as 
indicated on the Study Completion CRF), the number who withdrew prior to completing the 
study and reason(s) for withdrawal.  Summary data will be presented by dose group and overall. 
A by-subject data listing of study completion information including the reason for premature 
study withdrawal, if applicable, will be presented. 
4.2. 
Demographics and Baseline Characteristics 
Demographics and baseline characteristics will be summarized and presented by dose group and 
overall for the ITT population. 
Age, height, weight, and BMI will be summarized using descriptive statistics (number of 
subjects, mean, SD, median, minimum, and maximum).  Sex, race, ethnicity, and country will 
be summarized by presenting the numbers and percentages of subjects in each category. 
Baseline disease characteristics will be summarized by presenting the numbers and percentages 
of subjects with or without the V30M mutation and with or without prior exposure to TTR02.  
Concurrent use of TTR stabilizer (Tafamidis or Diflunisal) will also be summarized. 
All demographic and baseline data will be provided in data listings. 
Medical history and prior surgeries will be presented in a data listing.  Pregnancy and virology 
test results will be presented in data listings. 
4.3. 
Pharmacodynamic Evaluation 
4.3.1. 
Total Serum TTR (ELISA) 
Serial measurements and changes from baseline of serum TTR through Day 208 will be 
summarized for each scheduled time point using descriptive statistics.  Percent change from 
baseline will also be summarized.  Ninety-five percent CIs for percent change will be presented.  
An overall summary of percent reduction in TTR will include the maximum percent reduction 
per dose group, dose group means (SD) at individual and group nadirs (defined below), and 
dose group means (SD) at Day 28 and Day 56 (Day 21 and Day 42 for optional cohorts dosed 
every 3 weeks). 
The individual nadir TTR value, defined as the lowest observed TTR value from Day 1 to the 
Day 28 premedication assessment (Day 21 for optional cohorts dosed every 3 weeks), will be

determined for each subject.  The nadir value will be plotted for each subject, grouped by dose 
group.  Dose group means will be indicated on the plot.  The value of the percent reduction 
associated with the nadir will be plotted similarly.  The nadir value from the Day 29 to Day 56 
interval (Day 22 to Day 42 for optional cohorts dosed every 3 weeks) will also be determined 
and plotted. 
The group nadir TTR value, defined as the lowest observed mean percent TTR reduction from 
baseline from Day 1 to the Day 28 premedication assessment (Day 21 for optional cohorts dosed 
every 3 weeks), will be determined for each dose/regimen group.  The group nadir value will be 
plotted for each group, along with standard error bars.  The group nadir value from the Day 29 
to Day 56 interval (Day 22 to Day 42 for optional cohorts dosed every 3 weeks) will also be 
determined and plotted. 
The area under the concentration-time curve (AUC) will be calculated for serum TTR.  The 
AUC will be calculated using the daily TTR concentrations starting from baseline, defined as 
the average of all pre-dose values, and continuing to the Day 28 premedication assessment 
(Day 21 for optional cohorts dosed every 3 weeks).  The trapezoidal rule will be used for the 
calculation of AUC.  For the purpose of this AUC calculation, it is assumed that the collection 
times are in multiples of equal 24 hour intervals.  For example, the interval from Day 2 to Day 4 
will be 48 hours, irrespective of actual assessment times.  AUC will be summarized using 
descriptive statistics.  A similar calculation and summary will be performed for the AUC 
calculated from Day 28 to Day 56 (Day 21 to Day 42 for optional cohorts dosed every 3 weeks). 
TTR levels over time will be plotted.  Each subject’s TTR levels will be joined by a line, and 
each subject within a dose group will have a different symbol.  A separate plot will be produced 
for each dose group.  In addition, the average of each dose group (with standard error bars) will 
be plotted versus time.  Dose group means (with standard error bars) for percent change from 
baseline will be plotted over time. 
The pharmacodynamics assessment for use in the PK/PD analysis will be similar to that 
described above, but may include additional PD analyses which will be used for the purpose of 
PK/PD analysis.  The methods for the PK/PD analysis will be described in the PK and PK/PD 
analysis plans and the analysis result will be reported in the separate PK and PK/PD report 
which will be appended to the CSR.

Vitamin A and Retinol Binding Protein 
Observed values and changes from baseline in vitamin A through Day 208 will be summarized 
for each scheduled time point using descriptive statistics.  Percent change from baseline will 
also be summarized.  Ninety-five percent CIs for percent change will be presented. 
Vitamin A levels over time will be plotted.  Each subject’s vitamin A levels will be joined by a 
line, and each subject within a dose group will have a different symbol.  A separate plot will be 
produced for each dose group.  In addition, the average of each dose group (with standard error 
bars) will be plotted versus time.  Dose group means (with standard error bars) for percent 
change from baseline will be plotted over time.  Percent reduction from baseline at individual 
and group nadirs will be plotted as described above for serum TTR. 
The above summaries will also be performed for RBP. 
A scatter plot of total serum TTR protein versus vitamin A and RBP, all normalized to their 
respective baseline values, will be produced.  The plot will include Spearman’s correlation 
coefficients (ρ) and the p-values from the tests of ρ = zero, to assess the strength of the 
correlations between serum TTR and vitamin A and between serum TTR and RBP.

Duration of infusion will be summarized using descriptive statistics.  A summary of the 
numbers and percentages of subjects with a dose interruption will be provided.  Duration of 
interruption will be summarized using descriptive statistics.  Summary statistics will be 
provided for the total drug amount received by the subject and the total volume infused. 
All data related to study medication administration, including details on inpatient hospitalization 
for dosing, will be presented in a data listing. 
4.5.2. 
Adverse Events 
Adverse events will be displayed in tables and data listings using MedDRA system organ class

Analyses of AEs will be performed for those events that are considered treatment-emergent, 
where treatment-emergent is defined per protocol as any AE with onset during or after the 
administration of study medication through 28 days after dosing, or any event that was present 
pre-infusion but worsened in intensity or was subsequently considered drug-related by the 
Investigator. 
When determining whether an AE is treatment-emergent, partial dates will be handled as 
follows.  If the day of the month is missing, the onset day will be set to the first day of the 
month unless it is the same month and year as study treatment.  In this case, in order to 
conservatively report the event as treatment-emergent, the onset date will be assumed to be the 
date of treatment.  If the onset day and month are both missing, the day and month will be 
assumed to be January 1, unless the event occurred in the same year as the study treatment.  In 
this case, the event onset will be imputed as the day of treatment, in order to report the event 
conservatively as treatment-emergent.  A missing onset date will be imputed as the day of 
treatment.  If the resulting imputed onset date is later than a non-missing date of resolution, then 
the imputed onset date will be set to the resolution date.  The imputed data is used solely for the 
purpose of determining whether an AE is treatment-emergent; actual dates as recorded on the 
eCRF will be presented in subject listings. 
Adverse events are summarized by subject incidence rates; therefore, in any tabulation, a subject 
contributes only once to the count for a given SOC or preferred term. 
The numbers and percentages of subjects with any treatment-emergent adverse event (TEAE), 
with any TEAE assessed by the Investigator as related to treatment (definitely or possibly 
related), with any TEAE that is severe in intensity, with any serious TEAE, with any TEAE 
leading to discontinuation of study medication, or with any TEAE considered a DLT will be 
summarized by dose group and overall. 
Tabulations by SOC and preferred term will be produced for all TEAEs, for all related TEAEs, 
all TEAEs of severe intensity, all treatment-emergent IRRs, and for all serious TEAEs.  In these 
tabulations, each subject will contribute only once (i.e., the most related occurrence or the most 
intense occurrence) to each of the incidence rates in the descriptive analysis, regardless of the 
number of episodes of a given event (preferred term).  The most commonly occurring TEAEs, 
defined as those events experienced by at least 10% of all subjects, will be tabulated by 
preferred term in decreasing order in frequency.

Separate tables will present AE incidence rates by maximum relationship to study drug and by 
maximum severity.  Subjects who report multiple occurrences of the same AE (preferred term) 
will be classified according to the most related or most severe occurrence, respectively. 
No formal hypothesis-testing of AE incidence rates will be performed. 
All reported AEs will be provided in data listings, including AEs that are not treatment-

Laboratory Data 
Clinical laboratory values will be expressed in SI units. 
Descriptive statistics will be provided for the actual values and changes from baseline to each 
on-study evaluation for each clinical laboratory parameter, including hematology, clinical 
chemistry, LFTs, thyroid function tests, and coagulation studies.  Percent change from baseline 
will also be summarized. 
Descriptive statistics will be provided for CRP and cytokines at pre-dose and 2, 6, and 24 hours 
post-dose.  Change from pre-dose will also be summarized.  Fold change, as defined below, will 
be summarized for CRP.  Complement factor (Bb) will be summarized at pre-dose, and 
30 minutes, 2 hours and 24 hours post-dose.  Change and fold change from pre-dose will also be 
summarized.  Separate summaries will be presented for Dose 1 and Dose 2. 
Fold change from pre-dose is defined as the ratio of the post-dose value to the pre-dose value.  
Maximum fold change is defined as the ratio of the maximum post-dose value to the pre-dose 
value.  Maximum fold change from pre-dose for cytokines, complement factor (Bb), and CRP 
will be represented graphically in the form of a semi-log10 plot.  Maximum fold change will be 
plotted for each subject, grouped by dose level.  Data recorded as below the limit of detection 
will be set equal the lower limit of detection for the calculation of fold change.  Separate plots 
will be presented for Dose 1 and Dose 2. 
For each continuous laboratory parameter, results will be categorized as low, normal, or high 
based on the laboratory normal ranges.  Shift tables will be employed to summarize the pre-dose 
category versus the post-dose category, where the post-dose category will be based on the 
maximum observed value (in absolute value) subsequent to each dose.  For dose 1, the 
maximum value shall be selected from assessments performed through the Day 28 pre-dose

Figures will be produced for each dose group that display each subject’s AST, ALT, alkaline 
phosphatase, and bilirubin (total and direct) results over time; 1 figure will be produced for each 
dose group and liver function test parameter, with lines presenting subject results over time.  In 
addition, treatment group means, with standard error bars, will be plotted over time.  Similar 
plots will be produced for complement factor (Bb) and cytokines.  A vertical reference line will 
identify the nominal Dose 2 dosing day (i.e., Day 28 for the 4-week regimen or Day 21 for the 
3-week regimen). 
Urinalysis results will be included in subject listings but will not be included in summary tables. 
Tryptase and C3a will be included in subject listings for any subjects experiencing an IRR.

Vital Signs and Physical Examination 
Descriptive statistics will be provided for serial vital signs collected on each dosing day, 
including blood pressure, pulse rate, oral body temperature and respiration rate.  Pulse oximetry 
(SaO2) will be included with serial vital sign summaries.  Change from pre-dose to each 
post-dose assessment will also be summarized.  Treatment group means with standard error bars 
will be plotted over time for each serial vital sign assessment.  Separate plots will be presented 
for Dose 1 and Dose 2.  Routine vital signs will be included in subject listings but will not be 
summarized. 
Vital sign measurements will be presented for each subject in a data listing.  All physical 
examination findings will be presented in a data listing.

be summarized. 
Electrocardiogram data for each subject will be provided in a data listing. 
4.5.6. 
Concomitant Medications 
Concomitant medications will be defined as those medications that were initiated after first 
study drug administration or those that were ongoing at the time of the first study drug 
administration.  If a start date of a medication is missing, the drug will be assumed to be 
concomitant, unless an end date indicates otherwise.  If an end date is missing or the medication 
is ongoing, the medication will be considered concomitant. 
Concomitant medications will be coded using the WHO Drug Dictionary.  Subject incidence 
will be tabulated by Anatomic Therapeutic Class (ATC) and preferred term for each dose group 
and overall; subjects will only count once for each ATC or preferred term in the event that they 
have multiple records of the same ATC or preferred term in the database.  Medications taken as 
protocol specified premedications will be summarized separately. 
The use of concomitant medications, including protocol-specified premedications, will be 
included in a by-subject data listing.  Premedications will also be listed separately.
