2. INTRODUCTION
This SAP provides the detailed methodology for summary and statistical analyses of the data 
collected in Study B3461045. This document may modify the plans outlined in the protocol; 
however, any major modifications of the primary endpoint definition or its analysis will also 
be reflected in a protocol amendment.
2.1. Study Objectives
Primary Objectives:

To obtain additional, long-term, safety data for tafamidis in subjects with
transthyretin amyloid cardiomyopathy (ATTR-CM). 

To provide investigational product, tafamidis, to enrolled subjects until local
availability by prescription for the ATTR-CM indication.
2.2. Study Design
This is a Phase 3, open-label long-term extension safety study designed to obtain additional 
safety data for tafamidis meglumine 20 mg and 80 mg (or tafamidis 61 mg where available), 
and to continue to provide enrolled subjects with tafamidis for up to 60 months, or until 
subject has access to tafamidis for ATTR-CM via prescription, whichever occurs first. The 
study will also end before 60 months if the sponsor discontinues the study. Subjects 
withdrawn from the study due to commercial access to prescription tafamidis in their

respective countries will be considered study completers. The decision to withdraw subjects 
for transition to commercial tafamidis will be made by the sponsor. 
Eligible study participants will be enrolled in 2 Cohorts: 

Cohort A – Subjects diagnosed with ATTR-CM who completed 30 months of 
participation in Study B3461028. 

Cohort B – Subjects diagnosed with ATTR-CM who have not previously participated 
in Study B3461028.

Flowchart of Study Participation
Cohort A subjects receiving tafamidis meglumine 20 mg or 80 mg will be assigned to 
tafamidis 61 mg, once daily, in addition to standard of care (eg, diuretics), for up to 
60 months. Subjects will be assigned to tafamidis meglumine 80 mg in regions where 61 mg 
tafamidis is unavailable.
At enrollment, subjects in Cohort B will be assigned to open label 61 mg tafamidis once 
daily, in addition to standard of care (eg, diuretics), for up to 60 months. One dose reduction 
to 20 mg tafamidis meglumine will be permitted for adverse events related to tolerability. 
Subjects will be assigned to 80 mg tafamidis meglumine in regions where 61 mg tafamidis is 
unavailable.

4.3. Safety Analysis Set
The safety analysis population consists of all subjects (Cohorts A and B) who are enrolled in 
this study and who have taken at least one dose of study treatment.  
4.4. Other Analysis Sets
The “Combined Mortality Analysis Set” will include all subjects in the ITT-Analysis Set 
from B3461028. Mortality analyses in study B3461045 for Cohort A subjects will combine 
data from subjects in study B3461028, including subjects who died, discontinued in 
B3461028, or didn’t enroll into B3461045 (ie, ITT Analysis Set from B3461028) with 
mortality data through participation in the B3461045 study. This analysis set will be referred 
to as “Combined Mortality Analysis Set”.
5. GENERAL METHODOLOGY AND CONVENTIONS
The final analysis will be performed when all the subjects enrolled into the the study either 
discontinue (including deaths), or complete the study (60 months), or withdraws from the 
study due to commercial access to prescription tafamidis. Note that subjects withdrawn from 
the study due to commercial access to prescription tafamidis in their respective countries will 
be considered study completers. The study will also end before 60 months if the sponsor 
discontinues the study. Interim analyses may also be performed during the course of the 
study to allow for the reporting of data to the scientific community.

5.1. Hypotheses and Decision Rules
The primary objective of the study is to obtain additional, long term, safety data for tafamidis 
in subjects with transthyretin cardiomyopathy (ATTR-CM) and to provide investigational 
product, tafamidis, to ATTR-CM subjects who complete 30 months of blinded treatment on 
protocol B3461028 (Cohort A) and to Subjects diagnosed with ATTR-CM who have not 
previously participated in Study B3461028 (Cohort B). Therefore, only limited hypothesis 
testing ie, mortality and change from baseline in KCCQ for Cohort A subjects will be 
performed. All hypothesis testing will be conducted using two-sided tests with alpha = 0.05 
level of significance. Since the primary objective of the study is to collect safety information, 
no multiplicity adjustment will be done. No hypothesis testing will be done on Cohort B 
subjects.
5.2. General Methods 
For Cohort A, analyses will be performed using tafamidis/tafamidis and placebo/tafamidis 
treatment groups. Subjects randomized to tafamidis in parent study B3461028 and continue 
on tafamidis in the extension study B3461045 will be grouped as tafamidis/tafamidis. 
Subjects randomized to placebo in study B3461028 and randomized to tafamidis in the 
extension study B3461045 will be grouped as placebo/tafamidis. 
For Cohort B, since subjects in this Cohort will all be administered the same dose, only 
overall descriptive statistics will be provided.
5.3. Methods to Manage Missing Data
Other than standard approaches for missing dates for adverse events, no data imputation will 
be performed in the study. Missing data from Cohort A subjects who ended participation in 
B3461045 study without achieving the completion criteria of sustainable access to tafamidis 
by prescription, and allowed to return to the study and continue participation until they reach 
protocol defined study completion will not be imputed. Adverse events reported in the CRF 
that occurred between the time a subject ended the participation and subsequently returned
will be evaluated for treatment-emergence in the same manner as adverse events that 
occurred during the study participation. 
6. ANALYSES AND SUMMARIES
6.1. Primary Endpoint(s)
6.1.1. All-cause Mortality
For Cohort A subjects, time to all-cause mortality will be calculated from Day 1 of the Study
B3461028 based on the “Combined Mortality Analysis Set” as defined in Section 4.4. 
All-cause mortality will be analyzed using SAS Proc Lifetest; p-values will be from the 
log-rank test. Kaplan-Meier survival curves for each treatment group along with median 
survival times (if applicable) will be presented comparing tafamidis/tafamidis group with

All-cause mortality will also be analyzed using Cox proportional hazards model with 
treatment, NYHA baseline classification, and TTR genotype (variant and wild-type) as 
factors. Subjects who discontinue for transplantation (ie, heart transplantation and combined 
heart and liver transplantation) or for implantation of a cardiac mechanical assist device, will 
be handled in the same manner as death. Data from subjects who drop out for a liver-only
transplantation will be handled in the same manner as the data from all other censored 
subjects.
To examine the potential effect of including heart transplantation or cardiac mechanical assist 
device as “deaths” in the all-cause mortality analysis, a sensitivity analysis will be performed 
treating all transplantation or cardiac mechanical assist device in the same manner as any 
other censored observation.  
For Cohort B, since subjects in this Cohort will all be administered the same dose, only 
overall descriptive statistics will be provided. Kaplan-Meier survival curve along with 
median survival time (if applicable) will be presented.
6.2. Other Endpoint(s)
As a general rule, data from endpoints that are collected at “Month 3” either in France or 
Germany as part of the country-specific protocol amendment will be included in study 
listings and will be summarized descriptively at that time point but will not be included in 
any inferential analyses. Data at Month 3 from one or two countries will be limited and could 
lead to convergence issues for the models used in the inferential analyses. 
6.2.1. Cardiovascular-related Mortality
For both Cohort A and B, cardiovascular-related mortality will be analyzed separately similar 
to all-cause mortality detailed in Section 6.1.1. Cardiovascular relatedness will be based on 
an evaluation and clinical judgment of the MedDRA preferred terms. 
6.2.2. Hospitalization
The frequency (annualized rate) of all-cause and cardiovascular-related hospitalizations 
during the study will be summarized descriptively separately for Cohort A and B.
Cardiovascular relatedness will be based on an evaluation and clinical judgment of the 
MedDRA preferred terms.
6.2.3. Kansas City Cardiomyopathy Questionnaire
The KCCQ will be summarized by the following summary scores calculated using the 
guidelines established in the KCCQ scoring instructions from the developer:

Clinical summary score
For Cohort A, the overall, domain, and clinical summary scores will be evaluated as a change 
from baseline at each visit using a MMRM (repeated measures mixed model) with an
unstructured covariance matrix (or as appropriate) with center and subject-within-center as a 
random effects and treatment (tafamidis/tafamidis and placebo/tafamidis), visit, TTR 
genotype (variant and wild- type), and visit-by-treatment interaction, as fixed effects and 
baseline score as covariate. Data will also be summarized by each scheduled assessment.
As defined in Section 3.4, the baseline for Study B3461028 will be used as the baseline for 
all KCCQ based analyses. All visits from Study B3461028 will also be included in the 
repeated measures model described above.
For Cohort B, descriptive statistics for change from baseline at each post-baseline visit will 
be provided.
6.2.4. New York Heart Association
For Cohorts A and B, subjects will be evaluated using the New York Heart Association 
(NYHA) classification. Descriptive statistics (frequency) will be presented by clinic visit for 
each classification: Class I, Class II, Class III, and Class IV. The number and percentage of
subjects who improved, worsened, or with no change from baseline will also be presented at 
each visit via a shift table.
6.2.5. Body Mass Index/modified Body Mass Index
For Cohorts A and B, BMI and mBMI values at each visit and change from baseline will be 
presented in summary tables and data listings. Descriptive statistics will be provided by visit.
6.2.6. NT-proBNP and Troponin I
For Cohort A, as defined in Section 3.4, the baseline for Study B3461028 will be used as the 
baseline for all NT-proBNP and Troponin I based analyses. Change from baseline for all 
visits, including the visits from Study B3461028 will be summarized descriptively for 
NT-proBNP and Troponin I by treatment group (tafamidis/tafamidis and placebo/tafamidis).
For Cohort B, descriptive statistics for change from baseline at each post-baseline visit will 
be provided for NT-proBNP and Troponin I.

6.3. Subset Analyses 
All Cohort A and Cohort B analyses will be repeated by genotype (wild type and variant)
separately.
6.4. Baseline and Other Summaries and Analyses
Subjects disposition, demographics, treatment exposure, and concomitant medications will be 
summarized descriptively for both Cohort A and Cohort B separately.
6.5. Safety Summaries (including other endpoints)
All safety endpoints listed in this section will be analyzed descriptively for Cohorts A and B 
separately.
6.5.1. Adverse Events
All AE data collected on the CRF will be presented in summary tables and data listings. 
All adverse events that are observed from the time of first dosing with study medication until 
the treatment end date will be included in the safety analysis. Adverse events that occurred 
during treatment will be reported separately if the event occurred prior to randomization.
The effective duration of treatment is determined by the lag time. Any event occurring within 
the lag time, whether this occurs during a break in treatment or at the end of treatment, is 
attributed to the corresponding treatment period. A lag of 28 days will be used for this study. 
Treatment emergence is defined in Section 3.5.1.
All adverse events will be coded according to the Medical Dictionary for Regulatory 
Activities (MedDRA) and will be summarized by treatment group. The incidence of 
treatment-emergent adverse events will be tabulated by treatment group and by system organ
class. The incidence of treatment-emergent adverse events will be displayed by severity and 
attribution. In addition, the incidence of serious adverse events and adverse events that cause 
withdrawal will be tabulated. All adverse events will be listed. All subjects in both Cohort A
and B will be permitted one open label dose-reduction to 20 mg. All adverse events that led 
to temporary dose discontinuation or dose reduction will be summarized.
For Cohort A subjects who ended participation in B3461045 study without achieving the 
completion criteria of sustainable access to tafamidis by prescription, and allowed to return to 
the study and continue participation until they reach protocol defined study completion, 
adverse events that occurred between the time a subject ended the participation and 
subsequently returned will be collected and evaluated for treatment-emergence in the same
manner as adverse events that occurred during the study participation. 
Given that in B3461045 all subjects will be receiving active treatment, 3-tier analysis will not 
be performed on the adverse events.

6.5.2. Laboratory Data
All clinical laboratory data (serum chemistry, coagulation, hematology, and urinalysis) will 
be subjected to clinical review and summarized by frequency of events and mean changes 
from baseline.
There was a Quality Event investigation (PR 2163545) concerning repeated data for the 
assessment of respiratory rate and urine dipstick at site 1121. The investigation could not
confirm whether the repeated data was fraudulent or due to human error. To evaluate the 
impact of these findings on the overall interpretation of the endpoints potentially impacted, 
the laboratory analyses specified above will be repeated by excluding all subject data from
this site 1121. Overall results will be compared to summaries generated by excluding the site 
to assess if there was a meaningful impact on the clinical interpretation. 
6.5.3. Electrocardiogram
ECG values at each visit and change from baseline will be presented in summary tables and 
data listings. Descriptive statistics will be provided for each test result by visit.
Centrally over-read ECG variables will be summarized by mean change from baseline to end 
of study for heart rate, PR interval, QRS width, QT interval, and QTcB (Bazett’s correction) 
and QTcF (Fridericia’s correction) values. Additionally, the incidence of categorical 
increases in QTc intervals will be provided. Categories for QTcB and QTcF are ≥450 msec, 
≥480 msec, and ≥500 msec. Categories for QTcB and QTcF as change from baseline are: 
≥30 msec increase, ≥60 msec increase, and 75 msec increase. QTcF is considered the 
primary QTc value as this correction is anticipated to be more appropriate.
6.5.4. Physical Examinations and Vital Signs
Physical examinations and vital signs (lying and standing blood pressure and pulse, 
respiratory rate, and temperature) will be summarized using descriptive statistics.
To assess the impact of the findings in the Quality Event investigation  described in 
Section 6.5.2, vital signs summaries will also be generated by excluding all subject data from
site 1121. Overall results of vital signs will be compared to summaries generated by 
excluding the site to assess if there was a meaningful impact on the clinical interpretation.
7. INTERIM ANALYSES
7.1. Introduction
Interim analyses may be performed if required to meet regulatory requirements and as 
requested by the Data Monitoring Committee. Interim analyses may also be performed 
during the course of the study to allow for the reporting of data to the scientific community.
7.2. Interim Analyses and Summaries
Interim analyses will include either all the analyses or a subset of the summaries described in 
Sections 5 and 6.

Appendix 1.1. Definition and Use of Visit Windows in Reporting
For the purpose of this study, Day 1 is defined as the first dose day under this protocol 
(except for mortality-based endpoints,KCCQ, NT-proBNP, and Troponin I).
The following describes the clinical visit windows allowed within the protocol:
Clinic Visits (Months 6, 12, 18, 24, 30, 36, 42, 48, 54) ±2 weeks
End of Study Visit (Month 60) ±2 weeks or Early Study Discontinuation
However, in order to maximize the use of all available data, the visit windows for each visit 
are expanded as follows:
Clinic Visits (Months 6, 12, 18, 24, 30, 36, 42, 48, 54) ±3 months 
All nominal visits (months 6, 12, 18, 24, 30, 36, 42, 48, 54) will use the data as collected 
from that visit. Early termination visits will never replace an existing visit. If the visit 
covered by the windowing rules above is already populated with an existing nominal visit, 
then the early termination visit should be mapped forward to the next 6 month visit.
Data from endpoints that are collected at “Month 3” either in France or Germany as part of 
the country-specific protocol amendment will be summarized descriptively as 
‘Month 3- Unscheduled’ and will not be subject to the windowing rules described above.
Analyses of KCCQ, NT-proBNP, Troponin I will combine data from B3461028 study. For 
these endpoints, visits for B3461045 will be evaluated as “30 Months” plus the visit window
calculated using the B3461045 windowing rules specified above.
