1 INTRODUCTION 
1.1 Overview of Fabry Disease  
Fabry disease is a rare, progressive, debilitating, glycosphingolipid storage disorder.  It is caused 
by deficient activity of the lysosomal enzyme α-galactosidase A which results from a mutation in 
the α-galactosidase A gene (GLA), located on chromosome Xq22.1.  α-galactosidase A cleaves 
galactose in the alfa-anomeric configuration from glycosphingolipids, in particular 
globotriaosylceramide (Gb3).1  Mutations in the GLA gene lead to decreased or complete 
absence of enzyme activity that, in turn, result in accumulation of varying amounts of Gb3 in 
cells in vascular beds, cardiomyocytes and various other cells, tissues and organs throughout the 
body.  The clinical manifestations of Fabry disease typically include angiokeratomas, 
acroparesthesias, anhydrosis, anhedonia, chronic renal insufficiency leading to renal failure, 
hypertrophic cardiomyopathy with arrhythmias and infarction, and microvascular cerebral events 
including transient ischemic attacks (TIAs), stroke, and dolychoectasia.2  In general, patients 
with complete absence of α-galactosidase A have a classic phenotype with rapidly progressing 
renal, cardiac, and cerebrovascular events whereas patients with reduced α-galactosidase A have 
an attenuated clinical phenotype.3  
Clinical onset of Fabry disease typically occurs during childhood or adolescence with recurrent 
episodes of severe neuropathic pain in the extremities, characteristic cutaneous lesions known as 
angiokeratomas, and a distinctive but asymptomatic corneal dystrophy termed cornea verticillata.  
Vital organs, especially the heart, kidneys and brain, are progressively affected with increasing 
age.4  
In contrast to classical X-linked disorders, females may also be affected, presumably from biased 
X-linked inactivation and lack of cross-cellular correction of lyonized cells by normal cells.  
Females may inherit an X-linked Fabry mutation from either parent and are not asymptomatic 
carriers.  Females account for twice the number of male patients.  Clinically, manifestations in 
females range from mild to severe phenotypes.5,6  The onset of symptoms and age of diagnosis in 
females occur approximately 10 years later than in males.7  
Before the availability of dialysis or renal transplantation, renal complications accounted for the 
mortality of male Fabry patients during the fourth or fifth decade of life.8  Median age of death in 
males is 50 to 55 years of age.  Death in female patients with Fabry disease is, on average, a 
decade or more later than in males and occurs primarily as a result of cardiac or cerebrovascular 
complications.9,10  
Data on the true global incidence of Fabry disease are scarce and estimates vary among 
1:117,000, ~1:50,000 and ~1:4,600 live births.  Estimates suggest that the ratio of patients with 
the later-onset:  classic phenotypes are 7:1.11,12  
The diagnosis of Fabry disease may be made in males based on low levels of plasma or 
leukocyte α-galactosidase A activity or by the presence of a gene mutation.  In females, a 
presumptive diagnosis of Fabry disease may be based on the presence of characteristic clinical 
findings which must be confirmed by genotyping.

Prior to the advent of enzyme replacement therapy (ERT) in 2001, Fabry disease was an 
under-diagnosed condition that was primarily recognized in males with symptoms of the 
classical disease severity.  Women were rarely diagnosed.12-14  
1.2 Nonclinical Studies 
The nonclinical studies have demonstrated that agalsidase alfa is well-tolerated in acute 
toxicology studies in mice and rats and in multiple dosing studies in rats, rabbits, and monkeys.  
Toxicology studies have included a single-dose IV toxicology study in rats testing doses up to 
10.0 mg/kg, (a dose that is 50-fold greater than the standard human dose of 0.2 mg/kg EOW and 
25-fold greater than the maximum human dose of 0.4 mg/kg once weekly tested in clinical 
studies [TKT027]).  Chronic toxicology studies have included 13-week and a 26-week repeated 
IV dose studies in rats, and a 13-week repeated IV dose study in cynomolgus monkeys where 
doses up to 1 mg/kg/week were tested, which was 10-fold greater than the standard human dose 
and 2.5-fold greater than the maximum tested human dose.  None of these tests showed evidence 
of significant toxicity associated with agalsidase alfa.  In addition, an in vitro tumorigenicity 
study in cultured primary human embryonic kidney (pHEK) cells was performed, and this study 
demonstrated that agalsidase alfa did not alter the in vitro tumorigenicity or growth rates of 
normal primary human embryonic kidney (pHEK) cells (Data on file).  
Reproductive studies in male and female rats and female rabbits revealed no untoward effects on 
male or female reproductive function, histopathology of reproductive organs, or embryo-fetal 
development.  The pharmacokinetic (PK) properties and biodistribution of agalsidase alfa in 
mice, rats, rabbits, and monkeys have been well characterized.  Following a single IV 
administration, serum levels of agalsidase alfa followed a biphasic distribution in several animal 
species including rats and monkeys.  The elimination half-lives were less than 2 hours in all 
species, and serum levels returned to predose values 24 hours after administration.  Both the 
maximum serum concentration immediately after dosing and the area under the concentration 
time curve were approximately proportional to the administered dose in rats and monkeys.  
There were only minor effects on PK parameters following multiple dosing in rats and monkeys. 
Biodistribution studies in rats using 125I-labeled agalsidase alfa have demonstrated that 
significant amounts of agalsidase alfa can be found in key organs pathologically affected in 
Fabry disease after IV administration, in particular the kidney and heart.  Single and 
multiple-dose pharmacodynamic studies in knockout mice have demonstrated a significant 
reduction in Gb3 in the liver, heart, and kidney.  
Further details on the nonclinical studies are provided in the Investigator’s Brochure (IB). 
1.3 Previous Human Experience 
Clinical studies of agalsidase alfa have been conducted in the United States, United Kingdom, 
Canada, Australia, Europe, Brazil, and Japan.

The clinical development program has included 3 placebo-controlled clinical studies of 6-month 
dosing duration in adults (TKT003, TKT005, TKT010), and open-label maintenance studies for 
patients continuing from these and other studies (TKT006, TKT007, TKT011, TKT013, and 
TKT015).   
Additionally, a study in female patients (TKT014), a study in dialysis and renal transplant 
patients (TKT019), and a single center, open-label, compassionate use study (TKT012) have also 
been performed.  Three studies have been conducted in children, 2 completed (TKT023 and 
TKT5S001), and 1 ongoing, open-label maintenance study (TKT029).  An additional study 
(TKT028) is ongoing in patients with left ventricular hypertrophy. 
There are 3 additional studies currently ongoing:  Rep001a, a Phase IV study of alternative 
dosing regimens for Replagal in Canadian patients with Fabry disease; HGT-REP-059, a 
treatment protocol to provide access to Replagal for patients with Fabry disease in the United 
States; and HGT-REP-060, an open-label extension study for TKT028. 
Over 1000 patients have been treated worldwide with Replagal (agalsidase alfa).  In total, 
233 adults and 37 children received Replagal in Shire HGT-sponsored studies.  Long-term safety 
experience for patients up to 7.5 years demonstrates that Replagal therapy has been generally 
well tolerated in clinical studies, as well as in commercial and compassionate use. 
Additional details of these clinical studies are available in the IB. 
1.4 Current Therapies 
The current approved treatment for Fabry disease is ERT.  There are 2 products in this 
therapeutic class:  agalsidase alfa, (marketed under the trade name of Replagal® in countries 
outside the United States, by Shire HGT) and agalsidase beta, (Fabrazyme®; Genzyme).  Both 
are indicated for long-term treatment in patients with a confirmed diagnosis of Fabry disease 
(α-agalactosidase A deficiency).  Currently, only agalsidase beta is approved for use within the 
US.  Replagal is currently approved in more than 40 countries worldwide.   
1.4.1 Replagal (agalsidase alfa) 
Replagal is manufactured from agalsidase alfa using an aseptic filling process in a facility in 
compliance with current Good Manufacturing Practice (cGMP) regulations.  Replagal is 
formulated as a sterile product suitable for parenteral administration.  The formulation of 
Replagal includes sodium phosphate as a buffering agent, polysorbate 20 as a stabilizing agent, 
and sodium chloride as an isotonic agent. 
Replagal is intended for use as ERT for patients with Fabry disease.  It is anticipated that 
replacement of the deficient enzyme may contribute to correction of the enzymatic defect, and 
allow for improved metabolism of the natural substrate for the enzyme.  Over time, chronic 
replacement of the deficient enzyme could theoretically alter the natural history of Fabry disease, 
with concomitant improvements in renal and cardiac function, metabolism, neuropathic pain, and 
quality of life.

1.4.2 Differences Between Replagal and Fabrazyme Enzyme Replacement Therapies 
Replagal is produced by a genetically engineered continuous human cell line.  Fabrazyme is 
produced using a Chinese hamster ovary cell line.  Other differences include post-translational 
modification of mannose residues such as glycosylation, sialylation and phosphorylation, which 
can potentially influence the tissue uptake and the rate of development of antibodies to the 
exogenously administered enzymes.  Formulation excipients may also contribute to differences 
in individual patient sensitivities to the treatments. 
The global shortage of agalsidase beta has caused a significant number of patients 
(approximately 700 patients globally including 500 patients in the European Union [EU] since 
July 2009 by Company estimates) who were previously treated with agalsidase beta to switch to 
treatment with agalsidase alfa.  It is realized that patients switching from one ERT to another 
may be under the risk of carry-over effects such as emergence of adverse events observed on 
prior ERT or appearance of new clinical symptomology due to cross-reacting antibodies.  Safety 
reporting has been closely monitored.  There have been no unexpected safety findings and the 
safety profile has remained consistent over 9 years of cumulative experience. 
1.4.3 Summary of Known and Potential Risks and Benefits to Human Subjects 
A summary of the risks and benefits for Replagal is provided in the IB. 
1.5 Rationale 
The original Replagal New Drug Submission (NDS) was approved in Canada in 2004, indicated 
for long-term treatment in patients with Fabry disease.  In March 2009, Shire submitted a 
Supplemental NDS (sNDS) for Replagal bioreactor (agalAF1 or AF) drug substance process by 
implementing a bioreactor process in place of the previously employed roller bottle (RB) process 
and eliminating animal-sourced raw materials.  There are no changes to the Replagal drug 
product formulation, manufacturing site, manufacturing process, and container closure.  Supplies 
of the roller bottle Replagal (RB Replagal) are quickly dwindling in Canada, and this protocol 
provides a mechanism to maintain uninterrupted supply of Replagal to Canadian patients. 
AF Replagal is currently approved and commercialized in more than 30 countries including all 
EU member states, Australia, Croatia, Israel, Switzerland, Mexico, Argentina, and Paraguay.  
Safety data is available from approximately 1600 patients worldwide who are receiving 
commercially available AF Replagal.  No new safety concerns have been identified.

4 POPULATION SELECTION 
The population consists of Canadian patients with Fabry disease. 
Each patient must meet the following criteria to receive treatment: 
1. The patient has a documented diagnosis of Fabry disease. 
2. The patient is sufficiently compliant with study activities to participate in this treatment plan, 
as judged by the Investigator. 
3. The patient must meet current Canadian guidelines for enzyme replacement therapy for 
Fabry disease by having one of the following: 
a. Age-adjusted GFR <80 mL/min or a decline in GFR of >10% which is sustained for 
3 months and for which other causes of declining renal function have been excluded by a 
nephrologist.  
b. Evidence of cardiac involvement related to Fabry disease including cardiac hypertrophy, 
valvular disease, or conduction system abnormalities.  
c. Stroke or TIA prior to the age of 65 (documented by a neurologist) or unexplained 
progressive white matter changes consistent with microvascular changes on magnetic 
resonance imaging.  
d. Chronic, intractable diarrhea and/or abdominal pain/cramps, refractory to standard 
management for at least 1 year.  
e. Chronic, intractable neuropathic pain, refractory to analgesics and standard pain 
management for at least 1 year.  
 
Patients who meet any of the following criteria will be excluded from the study: 
1. The patient has experienced an anaphylactic or anaphylactoid reaction or other 
infusion-related reaction which, in the opinion of the Investigator, precludes further treatment 
with Replagal or may interfere with the interpretation of the study. 
2. The patient is otherwise unsuitable for the study, in the opinion of the Investigator.

5 STUDY TREATMENT(S) 
5.1 Description of Treatment(s) 
All patients in this study will receive Replagal at a dose of 0.2 mg/kg body weight administered 
as an IV infusion over 40 minutes EOW (±5 days).  Refer to the Pharmacy Manual for detailed 
instructions on special precautions and handling. 
5.2 Treatment Administration 
Replagal will be provided by Shire HGT in vials as a concentrate for solution for infusion.  
Replagal infusions may occur at the clinical site at home or at a qualified satellite treatment 
center at the investigator’s discretion.  Patients experiencing an infusion-related AE must receive 
their infusions at the clinical site until they have had 2 successive infusions without an 
infusion-related adverse event.  Patients receiving Replagal as home therapy are required to 
return to the clinical site for biannual safety visits as indicated in the schedule of events 
(Appendix 1).   
The qualified, trained medical personnel will follow the Study Procedure Manual provided 
separately from this protocol that outlines all operating procedures to be followed for this 
treatment protocol including drug transport, reconstitution, and the required patient assessments 
before, during, and after infusion of study drug.  Clinical evaluations will remain under the 
medical supervision of the Investigator. 
5.3 Selection and Timing of Dose for Each Patient 
Replagal will be administered at a dose of 0.2 mg/kg body weight as an IV infusion over 
40 minutes EOW (±5 days).

controlled, monitored container.  The vials should be stored in a refrigerator at 2 to 8°C (36 to 
46°F).  A minute amount of fine particulate matter, causing the solution to appear slightly hazy, 
may be present during storage. 
Chemical and physical in use stability can be found on the drug label.   
5.8 Investigational Product Accountability and Destruction 
The final disposition of all investigational product delivered to an Investigator must be recorded 
on a patient-by-patient basis.  The date and time of administration of the study drug will be 
documented on the appropriate case report form/electronic case report form (CRF/eCRF). 
All used, partially used, and unopened study drug vials must either be returned to the Sponsor or 
destroyed according to Sponsor requirements.

These samples will be screened using an enzyme-linked immunosorbent assay (ELISA).   
Positive samples will be isotyped (IgG, IgA, IgM, or IgE).  In addition, positive samples will be 
tested for enzyme neutralizing activity using an in vitro assay. 
6.9 Replagal Administration 
Patients will receive Replagal IV infusions EOW until Replagal is commercially available to the 
patient, or the patient’s participation or the study is discontinued.   
Replagal administration will occur as described in Section 5.2; home infusions may occur. 
6.10 Adverse Events Assessments 
6.10.1 Definitions 
6.10.1.1 Adverse Event Definition 
An adverse event (AE) is any noxious, pathologic, or unintended change in anatomical, 
physiologic, or metabolic function as indicated by physical signs, symptoms, and/or laboratory 
changes occurring in any phase of a clinical study, and whether or not considered study 
drug-related.  This includes an exacerbation of a pre-existing condition.  Adverse events will be 
collected from informed consent until 30 days after the last dose of study drug and/or until the 
event has been resolved/stabilized or an outcome is reached, whichever comes first.  For patients 
who discontinue or are withdrawn, AEs will be followed up to 30 days after their last infusion of 
Replagal. 
Adverse events include: 
• Worsening (change in nature, severity, or frequency) of conditions present at the onset of the 
treatment plan 
• Intercurrent illnesses 
• Drug interactions 
• Abnormal laboratory values (this includes significant shifts within the range of normal that 
the Investigator considers to be clinically important) 
• Clinically significant abnormalities in physical examination, vital signs, and weight 
 
Throughout the treatment protocol, the Investigator must record all AEs on the AE CRF/eCRF, 
regardless of the severity or relationship to study drug.  The Investigator should treat patients 
with AEs appropriately and observe them at suitable intervals until the events stabilize or 
resolve.  Adverse events may be discovered through observation or examination of the patient, 
questioning of the patient, complaint by the patient, or by abnormal clinical laboratory values, or 
abnormal electrocardiogram (ECG). 
In addition, AEs may also include unexpected laboratory values that become significantly 
out-of-range and determined to be clinically significant by the Investigator.   

Replagal® (agalsidase alfa) 
 
 
Treatment Protocol HGT-REP-081 Amendment 2 
 
06 December 2010 
Shire 
Confidential 
21 
In the event of an unexpected out-of-range value, the laboratory test should be repeated until it 
returns to normal or can be explained and the patient’s safety is not at risk. 
6.10.1.2 Infusion-related Adverse Event Definition 
An infusion-related adverse event will be defined as an adverse event that 1) begins either during 
or within 12 hours after the start of the infusion, and 2) is judged as possibly or probably related 
to study drug.  Infusion-related adverse events are to be managed as defined in Section 6.11. 
6.10.2 Performing Adverse Events Assessments 
Patients should be asked non-leading questions, eg, “How do you feel?” and further questions 
should be posed if there is indication of an AE.  The questioning should be conducted with due 
regard for objectivity and, in particular, the questioner should gather information regarding AEs 
from questioning the patient, spontaneous reporting by the patient, laboratory reports, and any 
health care provider’s observations. 
The onset date, resolution date, treatment administered, and outcome of each AE must be 
recorded on the appropriate CRF.  In addition, the relationship of each AE to study drug must be 
recorded. 
6.10.3 Timing of Adverse Event Assessments 
Adverse events will be assessed from the time the patient provides signed informed consent until 
30 days after the patient’s final infusion of Replagal on this treatment plan.  The final AE 
assessment may be performed at the clinical site or by telephone call. 
6.10.4 Relationship and Severity 
The National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) 
Version 3.0 grading scale should be referenced when assessing the severity of an AE.  If an AE 
is not described in the NCI CTCAE v3.0, the severity should be recorded based on the scale 
below.  The severity of all AEs/SAEs should be recorded on the appropriate CRF/eCRF page as 
Grade 1, 2, 3, or 4 corresponding, respectively, to a severity of mild, moderate, severe, or 
life-threatening. 
Relationship to Product(s) 
Definition 
Not Related 
Unrelated to study drug. 
 
 
Possibly Related 
A clinical event/laboratory abnormality with a reasonable 
time sequence to administration of study drug, but which 
could also be explained by concurrent disease or other 
drugs/chemicals. 
 
 
Probably Related 
A clinical event/laboratory abnormality with a reasonable 
time sequence to administration of study drug, unlikely to

Relationship to Product(s) 
Definition 
be attributable to concurrent disease or other drugs and 
chemicals and which follows a clinically reasonable 
response on de-challenge.   
The association of the clinical event/laboratory 
abnormality must also have some biologic plausibility, at 
least on theoretical grounds. 
 
AE Severity 
Definition 
Grade 1 (Mild) 
No limitation of usual activities. 
Grade 2 (Moderate) 
Some limitation of usual activities. 
Grade 3 (Severe) 
Inability to carry out usual activities. 
Grade 4 (Life-threatening) 
Immediate risk of death. 
 
6.10.5 Clarification Between Serious and Severe Adverse Events 
The term “severe” is often used to describe the intensity (severity) of a specific event (as in mild, 
moderate, or severe myocardial infarction); the event itself, however, may be of relatively minor 
medical significance (such as severe headache).  This is not the same as “serious,” which is 
based on the outcome or action criteria usually associated with events that pose a threat to life or 
functioning.  Seriousness (not severity) and causality serve as a guide for defining regulatory 
reporting obligations. 
6.10.6 Protocol Deviations for Medical Emergency or Adverse Events 
During and following a patient’s participation in the treatment protocol, the Investigator should 
ensure that adequate medical care is provided to a patient for any AEs, including clinically 
significant laboratory test results.  The Investigator should inform the patient, the patient’s 
parent(s), or the patient’s legally authorized representative when medical care is needed for 
intercurrent illness(es) of which the Investigator becomes aware.  In an emergency situation, the 
Investigator should contact the Shire HGT Medical Monitor. 
Only when an emergency occurs that requires an immediate deviation from the protocol for the 
safety of a patient, will there be such a deviation, and this will be only for that patient.  The 
Investigator or other physician in attendance in such an emergency must contact the Shire HGT 
Medical Monitor as soon as possible.  The Investigator, along with the Shire HGT Medical 
Monitor, will make a decision as to whether or not the patient should continue in the treatment 
protocol.  The departure from the protocol and the grounds for it should be stated in the CRF.

6.11 Management of Infusion-related Adverse Events 
If a patient has an infusion-related adverse event during the infusion of study drug, the 
Investigator should decide, based on his or her clinical judgment, whether the infusion should be 
slowed, or temporarily or permanently discontinued.  Infusion-related adverse events that occur 
post-infusion should be assessed and treated in a similar manner.   
Patients experiencing a recurrent infusion-related adverse event may be premedicated.  If 
infusions continue without incident, then tapering of medications can be considered.  
In case of severe infusion-related adverse events, the Investigator should consult with the Shire 
HGT Medical Monitor prior to the patient’s next dose to determine the appropriate course of 
action for future infusions. 
6.12 Serious Adverse Events 
6.12.1 Definition 
A serious adverse event (SAE) is defined by federal regulation as any AE occurring at any dose 
that results in any of the following outcomes:  death, life-threatening AE, hospitalization or 
prolongation of existing hospitalization, a persistent or significant disability/incapacity, or a 
congenital anomaly/birth defect. 
Important medical events that may not result in death, be life threatening, or require 
hospitalization may be considered an SAE when, based upon appropriate medical judgment, they 
may jeopardize the subject and may require medical or surgical intervention to prevent one of the 
outcomes listed in this definition.  Examples of such medical events include allergic 
bronchospasm requiring intensive treatment in an emergency room or at home, blood dyscrasias 
or convulsions that do not result in inpatient hospitalization, or the development of drug 
dependency or drug abuse. 
Hospitalizations, which are the result of elective or previously scheduled surgery for preexisting 
conditions, which have not worsened after initiation of treatment, should not be classified as 
SAEs.  For example, an admission for a previously scheduled ventral hernia repair would not be 
classified as an SAE.  If however complications were to develop they would be evaluated to 
determine if serious criteria had been met. 
6.12.2 Reporting Serious Adverse Events 
Any SAE, regardless of relationship to study medication and which occurs in a patient after 
informed consent is obtained, should be recorded by the clinical site on a SAE form that is to be 
transmitted to the Shire HGT Medical Monitor and Shire’s Global Pharmacovigilance 
Department at the fax contact number provided below.  The SAE must be completely described 
on the patient’s CRF/eCRF, including the judgment of the Investigator as to the relationship of 
the SAE to the study drug.  The Investigator will promptly supply all information identified and 
requested by Shire HGT (and/or contract research organization [CRO]) regarding the SAE.  The 
Investigator must report the SAE to Shire Global Pharmacovigilance and to the Shire HGT 
Medical Monitor on a SAE form.

The Investigator must promptly report in a timely manner to his/her IRB/IEC/REB, all SAEs and 
any unanticipated problems involving risk to human patients.  It is the responsibility of Shire 
HGT to ensure that each Investigator receives a copy of any CIOMS I/Med Watch report that has 
been submitted to the appropriate regulatory agency(ies) notifying them of a related 
SAE/SUSAR.  The Investigator or Shire HGT must ensure that the IRB/IEC/REB receives a 
copy of the report and that a copy is also filed within their study files.  In addition, Shire HGT 
will also notify the Investigators and IRBs/IECs/REBs of any deaths occurring during the 
treatment protocol. 
6.13 Pregnancy 
The Sponsor must be notified in the event of a pregnancy occurring during the course of the 
study and through 30 days after the patient’s last dose of study drug.  Pregnancy is not to be 
reported as an AE; the pregnancy form should be used to report the pregnancy.  The pregnancy 
will be followed through delivery or final outcome. 
6.14 Removal of Patients from the Study 
Patients may withdraw from the treatment protocol at any time.  The Investigator or Sponsor 
may withdraw a patient from the treatment protocol for the following medical or administrative 
reasons: 
• Adverse Event:  If a patient experiences an AE which, in the judgment of the Investigator, 
the Sponsor, or the Shire HGT Medical Monitor, presents an unacceptable consequence or 
risk to the patient, the patient will be withdrawn from the treatment protocol. 
• Adverse Laboratory Experience:  If a patient has an adverse laboratory experience which, in 
the judgment of the Investigator, the Sponsor, or the Shire HGT Medical Monitor, presents 
an unacceptable consequence or risk to the patient, the patient will be withdrawn from the 
treatment protocol. 
• Comorbidity:  If a patient develops a comorbidity during the course of the treatment protocol 
that is not associated with the condition under study, and which requires treatment that is not 
consistent with protocol requirements, the patient will be withdrawn from the treatment 
protocol.  A patient will be withdrawn from the treatment protocol if, in the judgment of the 
Investigator, s/he develops an intercurrent illness that, in any way, justifies his withdrawal. 
• Refusal of Treatment:  If for any reason the patient refuses treatment during the treatment 
protocol, the patient will be withdrawn from the treatment protocol, and the reason for refusal 
will be documented on the CRF.  Reasonable efforts will be made to monitor the patient for 
AEs following such discontinuation.  Such efforts will be documented in the CRF. 
• Withdrawal of Informed Consent:  A patient may withdraw his informed consent to 
participate in the treatment protocol at any time and for any reason. 
• Lack of Efficacy:  The patient will be withdrawn from the treatment protocol if, in the 
opinion of the CFDI Investigator, a lack of efficacy is observed.  
 
At the time of discontinuation or withdrawal, patients will undergo all safety and efficacy 
evaluations required for the End of Study visit.  The Investigator will complete the appropriate 
CRF describing the reason for discontinuation.

In addition, patients who withdraw or are discontinued will have a follow-up assessment for 
safety at the clinical site 30 days after their last infusion of Replagal. 
6.15 Institutional Review Board /Independent Ethics Committee /Research Ethics 
Board (REB) 
Before initiation of the treatment protocol, the Investigator must provide the Sponsor with a copy 
of the written IRB/IEC/REB approval of the protocol and the informed consent form.  This 
approval must refer to the informed consent form and to the study title, study number, and 
version and date of issue of treatment protocol, as given by the Sponsor on the cover page of the 
protocol.  Local IRBs may be given the option to delegate to the central IRB identified for the 
study. 
Status reports must be submitted to the IRB/IEC/REB at least once per year.  The IRB/IEC/REB 
must be notified of completion of the treatment protocol.  Within 3 months of treatment protocol 
completion or termination, a final report must be provided to the IRB/IEC/REB.  A copy of these 
reports shall be sent to the study clinical monitor.  The Investigators must maintain an accurate 
and complete record of all submissions made to the IRB/IEC/REB, including a list of all reports 
and documents submitted.  Adverse events which are reported to Health Canada or other 
regulatory agencies must be submitted promptly to the IRB/IEC/REB. 
6.16 Ethical Conduct of the Study 
The procedures set out in this study protocol, pertaining to the conduct, evaluation, and 
documentation of this study, are designed to ensure that the Sponsor and Investigators abide by 
good clinical practice (GCP) as described in the 21 CFR Parts 50, 56, and 312 and the 
International Conference on Harmonisation (ICH) GCP Guidelines Compliance with these 
regulations and guidelines also constitutes compliance with the ethical principles described in the 
Declaration of Helsinki. 
6.17 Patient Information and Informed Consent 
Before enrolling in the treatment protocol, each patient, the patient’s parent(s), or the patient’s 
legally authorized representative(s) must consent to participate after the nature, scope, and 
possible consequences of the treatment protocol have been explained in a form understandable to 
him/her.  An informed consent form that includes information about the treatment protocol will 
be prepared and given to the patient, the patient’s parent(s), or the patient’s legally authorized 
representative.  This document will contain all Health Canada and ICH-required elements.  The 
informed consent form must be in a language understandable to the patient, the patient’s 
parent(s), or the patient’s legally authorized representative(s) and must specify who informed the 
patient, the patient’s parent(s), or the patient’s legally authorized representative(s). 
After reading the informed consent document, the patient, the patient’s parent(s), or the patient’s 
legally authorized representative must give consent in writing.  The patient’s consent must be 
confirmed at the time of consent by the personally dated signature of the patient, the patient’s 
parent(s) or the patient’s legally authorized representative and by the personally dated signature 
of the person conducting the informed consent discussions.

If the patient, the patient’s parent(s), or the patient’s legally authorized representative is unable to 
read, oral presentation and explanation of the written informed consent form and information to 
be supplied to the patient must take place in the presence of an impartial witness.  Consent must 
be confirmed at the time of consent orally and by the personally dated signature of the patient, or 
by a local legally recognized alternative (eg, the patient’s thumbprint or mark) or by the 
personally dated signature of the patient’s parent(s) or the patient’s legally authorized 
representative.  The witness and the person conducting the informed consent discussions must 
also sign and personally date the informed consent document.  It should be recorded and dated in 
the source document that consent was given. 
A copy of the signed and dated consent document(s) must be given to the patient, the patient’s 
parent(s), or the patient’s legally authorized representative.  The original signed consent 
document will be retained by the Investigator. 
The Investigator will not undertake any measures specifically required solely for the treatment 
protocol until valid consent has been obtained. 
A model of the informed consent form to be used in this treatment protocol will be provided to 
the sites separately from this protocol. 
Where applicable, signed assent(s) to participate in the treatment protocol will be obtained. 
6.18 Patient Confidentiality 
Patient names will not be supplied to the sponsor.  Only the patient number and patient initials 
will be recorded in the CRF/eCRF, and if the patient name appears on any other document, it 
must be obliterated before a copy of the document is supplied to the Sponsor.  Study findings 
stored on a computer will be stored in accordance with local data protection laws.  The patients 
will be told that representatives of the sponsor, a designated contract research organization 
(CRO), the IRB/IEC/REB, or regulatory authorities may inspect their medical records to verify 
the information collected, and that all personal information made available for inspection will be 
handled in strictest confidence and in accordance with local data protection laws.  The 
Investigator will maintain a personal patient identification list (patient numbers with the 
corresponding patient names) to enable records to be identified. 
6.19 Case Report Form Completion 
Case Report Forms (paper or electronic) are provided for each patient.  All forms must be filled 
out by authorized study personnel.  All corrections to the original CRF entry must indicate the 
reason for change.   
The Investigator is required to sign the CRF after all data have been captured for each patient.  If 
corrections are made after review and signature by the Investigator, he or she must be made 
aware of the changes, and his or her awareness documented by resigning the CRF.

Monitoring procedures that comply with current GCP guidelines will be followed.  Review of 
the CRF's for completeness and clarity, cross-checking with source documents, and clarification 
of administrative matters will be performed. 
The study will be monitored by the Sponsor or its designee.  Monitoring will be performed by a 
representative of the Sponsor (Clinical Study Monitor) who will review the CRFs and source 
documents.  The site monitor will ensure that the investigation is conducted according to 
protocol design and regulatory requirements by frequent site visits and communications (letter, 
telephone, and facsimile). 
6.21 Regulatory Administration 
Appropriate regulatory documentation will be collected as mandated by Health Canada. 
6.22 Premature Closure of the Treatment Protocol 
6.22.1 Treatment Protocol Termination 
If the sponsor or an Investigator discovers conditions arising during the treatment protocol which 
indicate that the clinical investigation should be halted due to an unacceptable patient risk, the 
treatment protocol may be terminated after appropriate consultation between Shire HGT and the 
Investigators.   
In addition, a decision on the part of Shire HGT to suspend or discontinue development of the 
test material may be made at any time. 
6.22.2 Site Termination 
A specific site may be terminated separate from the general treatment protocol for, but not 
limited to, the following conditions: 
• The discovery of an unexpected, significant, or unacceptable risk to the patients enrolled at 
the site. 
• Insufficient adherence by the Investigator to protocol or regulatory requirements. 
 
6.23 Record Retention 
Essential documents should be retained by the site for at least 2 years after the last approval of a 
marketing application and until there is no pending or contemplated marketing applications or at 
least 2 years have elapsed since the formal discontinuation of clinical development of the 
investigational product.  The sponsor will notify the Investigator if these documents must be 
retained for a longer period of time.  It is the responsibility of the Sponsor to inform the 
Investigator/institution as to when these documents no longer need to be retained. 
Records will be maintained by the Sponsor for a period of 25 years and will be accessible for 
onsite inspection by Health Canada inspectors.

Infusion information will be listed by patient and visit.  The cumulative dose of study drug taken, 
and the duration of study drug exposure will be summarized descriptively. 
7.4 Anti-agalsidase alfa Antibodies 
Antibody data will be listed by patient and visit.  The status of antibodies and neutralizing 
antibody will be summarized descriptively. 
7.5 Adverse Events and Other Safety Assessments 
Adverse event tabular summaries will be based on all treatment-emergent adverse events 
recorded; AEs will be coded using the MedDRA coding dictionary. 
AEs will be summarized by system organ class (SOC) and preferred term.  The total number of 
AEs by SOC and preferred term, as well as the number and proportion of patients experiencing 
an AE will be tabulated; a patient will be counted only once within each SOC and preferred term.  
AEs by SOC and preferred term will be tabulated by severity.  In the case of multiple 
occurrences of the same AEs (at the preferred term level) in an individual patient, the AE that is 
classified as the most severe (ie, maximum severity) will be identified for the analysis by 
severity.  In addition, AEs by SOC and preferred term will be tabulated by relationship to study 
drug by reporting the episode with the closest relationship to study drug. 
The number and percentage of patients reporting serious adverse events will be presented by 
SOC and preferred term; in addition, an SAE listing will be presented.

The number and percentage of patients reporting an infusion-related adverse event will be 
presented by SOC and preferred term.  An infusion-related adverse event is defined as an AE 
that:  (1) begins either during or within 12 hours after the start of the infusion, and (2) is judged 
by the investigator to be possibly or probably related to study drug. 
The number and proportion of patients experiencing an AE(s) that led to permanent 
discontinuation will be summarized by SOC and preferred term.  Furthermore, a listing of all 
patients who permanently discontinued due to an AE(s) will be provided. 
Furthermore, safety will be evaluated by assessing vital signs and blood tests.  Data for vital 
signs and blood tests will be listed for each patient and abnormal values will be flagged.  Shift 
tables from baseline to last visit may be presented for vital signs, and a summary table may be 
presented for blood tests.

Appendix 3 
Justification for Amendments and Summary of Changes 
Amendment 1: 
The protocol was submitted to Health Canada on 8 October 2010 as part of a Treatment Use 
Clinical Trial Application.  The Agency requested several changes and additions to the protocol 
(Clarifax 2 November 2010) and the changes proposed by Shire were approved by the Agency, 
on 4 November 2010.  The amendment incorporates changes that address comments received 
from the Agency. 
Changes to the amendment are detailed below.  New text is indicated as bold font, and deleted 
text is indicated as strikethrough. 
Section 3:  Overall Design and Plan 
Health Canada requested that a minimum number of patients be specified in order to obtain 
meaningful safety data from this safety clinical trial.  Shire plans to include a minimum number 
of 60 patients.  With a minimum of 60 subjects, there will be at least a 95% chance of observing 
at least one AE of a given type, if the event has a frequency of 5%. 
The amended text reads as follows: 
Approximately 150 patients are expected to participate in this treatment protocol, although the 
number may be increased or decreased depending upon patient need or patient availability A 
minimum of 60 patients and up to 150 patients are expected to participate in this protocol.  
Patients may begin to enroll in the treatment protocol as soon as the eligibility criteria are 
fulfilled and informed consent is signed. 
Other sections affected by this change:  Synopsis 
Section 4:  Population Selection 
Health Canada requested that the following be added as exclusion criteria. 
Patients who meet any of the following criteria will be excluded from the study: 
1. The patient has experienced an anaphylactic or anaphylactoid reaction or other 
infusion-related reaction which, in the opinion of the Investigator, precludes further 
treatment with Replagal or may interfere with the interpretation of the study 
2. The patient is otherwise unsuitable for the study, in the opinion of the Investigator. 
 
Other sections affected by this change:  None 
Section 6.2:  Disease and Treatment History 
The screening period for the study has been clarified.  Screening data will be obtained during the 
6 months prior to the patient’s initiation of treatment with Replagal, to align with the patients’ 
current biannual assessment schedule in the CFDI.  The added text reads: 

Replagal® (agalsidase alfa) 
 
 
Treatment Protocol HGT-REP-081 Amendment 2

Shire 
Confidential 
36 
Documentation of diagnosis with Fabry disease will be collected up to 6 months prior to the 
patient receiving the first dose of Replagal. 
Other sections affected by this change:  Section 6.4, Medical History; Appendix 1, Schedule of 
Events 
Section 6.14:  Removal of Patients from Study Drug 
Health Canada requested that “lack of efficacy” be included as a criterion for withdrawal from 
the study. 
The added text is the last bullet in the list: 
• Lack of Efficacy:  The patient will be withdrawn from the treatment protocol if, in the 
opinion of the CFDI Investigator, a lack of efficacy is observed.   
 
Other sections affected by this change:  None 
Amendment 2: 
The protocol was amended to address several minor inconsistencies.  Also, the procedures for 
study monitoring were clarified. 
6.10.1.2 
Infusion-Related Adverse Event Definition 
An infusion-related adverse event will be defined as an adverse event that 1) begins either during 
or within 12 hours after the start of the infusion, and 2) is judged as possibly or probably related 
to study drug.  Infusion-related adverse events are to be managed as defined in Section 6.11 
Section 6.20:  Study Monitoring 
The text has been amended to clarify the procedures used for study monitoring.   
Formerly read: 
Site qualification and initiation will be completed via teleconference.  Investigator site 
monitoring will be done remotely at up to 10% of the total number of sites with the exception of 
‘for cause’ on site monitoring visits. 
Now reads: 
Monitoring procedures that comply with current Good Clinical Practice (GCP) guidelines will be 
followed.  Review of the CRF's for completeness and clarity, cross-checking with source 
documents, and clarification of administrative matters will be performed. 
The study will be monitored by the Sponsor or its designee.  Monitoring will be performed by a 
representative of the Sponsor (Clinical Study Monitor) who will review the CRFs and source 
documents.

The site monitor will ensure that the investigation is conducted according to protocol design and 
regulatory requirements by frequent site visits and communications (letter, telephone, and 
facsimile). 
Other sections affected by this change:  None 
Appendix 1: 
Subject weight is required to ensure correct dosing.  The physical examination is listed with 
weight required at certain visits, but a separate row has been added for weight and noted that 
weight should also be measured during the Week 1 visit prior to the first dose of Replagal. 
Other sections affected by this change:  None
