TITLE 
Open Label Interventional Multicenter Phase 3b Study to Evaluate Skeletal 
Response to Eliglustat in Adult Patients Who Successfully Completed the 
Phase 2 or Phase 3 Studies 
INVESTIGATOR/TRIAL LOCATION 
The study centers that participated in the eliglustat Phase 2 or Phase 3 
studies are eligible to participate in this study.   
PHASE OF DEVELOPMENT 
Phase 3b 
STUDY OBJECTIVE(S) 
 
Primary objective 
Evaluate long term skeletal response to eliglustat in adult patients who 
successfully completed one of the Phase 2 or Phase 3 eliglustat studies. 
Secondary objective(s)  
Evaluate the safety of eliglustat (by (serious) adverse event (AE) continuous 
monitoring), the quality of life (Short Form-36 Health Survey (SF-36)) and 
biomarkers of Gaucher disease type 1 (GD1) (chitotriosidase, plasma 
glucosylceramide (GL-1) and lyso glucosylceramide (lyso-GL-1)) in adult 
patients who successfully completed one of the Phase 2 or Phase 3 studies. 
STUDY DESIGN 
This is an open label, interventional, non-comparative, multicenter, 
multinational Phase 3b study to evaluate long term skeletal response to 
eliglustat and eliglustat safety and effect on quality of life in adult patients who 
successfully completed one of the Phase 2 or Phase 3 studies in the eliglustat 
program. This study is considered an extension of these previous studies and 
will continue to evaluate the safety of eliglustat and patients’ quality of life 
(SF-36).  
Participating investigators will enroll patients who successfully completed one 
of the Phase 2 or Phase 3 studies. Patients will be treated for a minimum of 
2 years and up to 4 years, or until eliglustat is approved and available to 
patients through reimbursement.  If after 4 years since the beginning of the 
study eliglustat is not approved and available to patients in participating 
country, patients in this country may continue to receive study treatment until 
eliglustat is available to patients through the compassionate use (expanded 
access) program or is approved and available through reimbursement, 
whichever comes first.

ENDPOINT(S) 
 
Primary endpoint 
The main purpose in this extension study is to evaluate long term skeletal 
response to eliglustat, i.e., change in bone disease after 2 years of additional 
treatment with eliglustat. The elements of bone disease to be evaluated 
include bone pain, bone crisis, mobility, bone marrow infiltration,  bone 
mineral density (BMD), lytic lesions, infarcts, fractures, osteonecrosis, and 
bone biomarkers (Procollagen type I N-terminal propeptide (P1NP; bone 
formation) and C- terminal telopeptide (CTX; bone resorption), and 
macrophage inflammatory protein-1 beta (MIP-1 β). These efficacy 
assessments will be collected at baseline and thereafter at twice-yearly (bone 
biomarkers) or yearly (pain, crisis, mobility, bone marrow infiltration, bone 
mineral density, lytic lesions, infarcts, fractures) intervals. 
Secondary endpoint(s) 
Evaluation of patients’ quality of life (Short Form-36 Health Survey) and 
biomarkers of GD1 (chitotriosidase, plasma GL-1 and lyso-GL-1). Quality of 
Life (QOL) and biomarkers of GD1 will be performed at baseline and twice 
yearly.  
The safety of eliglustat (i.e., incidence of (S)AEs, concomitant medications, 
changes from study baseline in physical examinations, routine laboratory 
assessments (hematology) and pregnancy testing for female patients of 
childbearing potential). Safety assessments will be performed at baseline and 
twice yearly. Continuous monitoring will be performed for (S)AEs and

concomitant medications.   
ASSESSMENT SCHEDULE 
V1-2 (Day -45 to -1): screening 
V3 (D1): baseline, 1st  eliglustat administration in this study  
From V3 onwards, at 6 month intervals up to 4 years or until eliglustat is 
approved and available to patients through reimbursement or through the 
compassionate use (expanded access) program: efficacy, safety and general 
patient condition assessment parameters 
Last visit: last dose of IMP; efficacy, safety and general patient condition 
assessment parameters. 
For all visits, a time frame of ± 14 days is acceptable, using Day 1 as 
reference (If one visit date is changed, the next visit should take place 
according to the original schedule). 
Note: patients who prematurely discontinue treatment have to perform the 
discontinuation visit. 
STATISTICAL CONSIDERATIONS 
 
Sample size determination: 
This study will enroll all eligible patients having successfully completed one of 
the Phase 2 or Phase 3 trials (approximately 32 patients). 
Analysis population: 
Efficacy analyses will be performed on the Full Analysis Set (FAS) population, 
defined as all patients who enroll in this study and who received at least 
1 dose of eliglustat treatment in this study.  
Safety analyses will be performed on the Safety Set, which is equivalent to 
the FAS for this study. 
Primary analysis: 
Analysis will be performed at two time points in this study. The main analysis 
will be performed after all patients have completed the 2 year assessments 
(two-year analysis period). An additional analysis will be performed upon 
study completion. For both efficacy and safety outcomes summary statistics 
will be calculated and presented. Hypothesis testing will not be performed.  
For bone disease outcomes, summary statistics as well as cumulative 
incidence and incidence rates will be calculated, as appropriate. For 
continuous variables, change from study baseline as well as change from 
eliglustat baseline, defined as the change from first dose of eliglustat in the 
Phase 2 or 3 study, will be presented. Incidence and incidence rates will also 
be calculated separately, from study baseline and eliglustat baseline. 
Analysis of secondary endpoints: 
Quality of Life assessments, physical examinations, hematology, biomarkers 
and pregnancy testing for female patients of childbearing potential will be 
summarized at each time point.  Additionally, the change from study baseline 
and eliglustat baseline (1st dose received in the previous study) will be 
summarized, as appropriate. Adverse experience will be coded using the 
Medical Dictionary for Regulatory Activities (MedDRA) Version 18.0 or higher. 
All adverse experiences will be summarized by body system and MedDRA 
preferred term (PT) overall, by relationship and severity and seriousness. All 
deaths will be summarized. Concomitant medications will be reported.

a Final GZGD00304, GZGD02507, GZGD02607 and GZGD03109 study assessments may serve as entry evaluation for this study if performed less than 3 month for laboratory testing, 1 year for bone imaging (X-ray 
femur and lumbar spine, dual-energy X-ray absorptiometry (DXA) hips and lumbar spine, Magnetic Resonance Imaging (MRI) femur and lumbar spine) and 6 months for other assessments. 
However, safety (S)AE, concomitant medication and prior medication history, physical examinations, human immunodeficiency virus (HIV) antibody, hepatitis C antibody, or hepatitis B surface antigen, blood pregnancy 
test for female of childbearing potential, height, will have to be performed in all cases. 
The screening procedures do not have to be performed over 2 visits. Scheduling will be based on investigator, patient and resources availability. Screening can be performed at the same time as the end-of-study visit 
of the previous study the patient was enrolled in. 
b Study duration will be up to 4 years, or until eliglustat is approved and available to patients through reimbursement with minimum duration of 2 years. If after 4 years since the beginning of the study eliglustat is not 
approved and available to patients in participating country, patients in this country may continue to receive study treatment until eliglustat is available to patients through the compassionate use (expanded access) 
program or is approved and available through reimbursement, whichever comes first.  At study completion or patient discontinuation/withdrawal certain radiological assessments will not be repeated (bone X-Ray if 
performed less than 2 years prior; DXA, bone MRI and liver and spleen MRI if performed less than 1 year prior). 
c A unique patient ID number will be assigned. The ID of the previous study the patient was enrolled in and the patient’s ID in that study will be collected in the new clinical database. 
d Medico-surgical history already collected in the previous study database should not be re-entered. Should be entered in the Medical/surgical history CRF 1/ adverse events (AEs) started during the previous study, 
which are closed at the time of the screening visit and are still considered clinically significant by the investigator at the time of the screening visit; 2/ medical/surgical events started after the follow-up phone call of the 
previous study and before the ICF signing in the current study, whether ongoing or closed, if they are considered clinically significant by the investigator.  
e Prior medications are all ongoing medications at the time of screening, and medications received during the 30 day period prior to screening even if no longer taken at the time of screening, including eliglustat and 
enzyme replacement therapy (ERT). 
f 
Only at Study completion visit and not at Patient discontinuation/withdrawal visit. 
g Patients will be contacted approximately every 4 weeks for safety monitoring and will be asked if they have had any significant experiences, begun taking any new medications, changed the dose of any medications 
they are taking. In addition patients of child bearing potential will be asked about the result of the urine pregnancy test performed every 4 weeks at home.  
h Serum samples for CTX should be collected after overnight fasting. 
i 
Urine pregnancy test must be performed before radiological assessments and the result provided to the personnel performing the assessment so that he/she can verify the result is negative and sign off on it before 
performing the exam. All positive urine pregnancy tests will be verified with a blood pregnancy test. 
Note:  
Central reading will be set up for liver and spleen MRI and bone imaging. All laboratory tests will be done at the local laboratories at the exception of the biomarkers, which will be done in central laboratories. 
Cytochrome P450 2D6 URM patients will have liver and spleen MRI and hematology performed every 6 month till week 52. However, the frequency of liver and spleen MRI and hematology can be increased to every 3 
month till week 52 at the discretion of the Investigator. After week 52 CYP2D6 URM patients will follow the standard schedule. 
Although pharmacokinetic (PK) samples are not scheduled, unscheduled PK samples may be collected after discussion between PI and Genzyme.

INTRODUCTION AND RATIONALE 
Sanofi Genzyme has developed Cerdelga® (International Nonproprietary Name: eliglustat) as an 
oral therapy for Gaucher disease type 1.  Eliglustat is a member of a class of glucosylceramide 
(GL-1) synthase inhibitors that resemble the substrate (ceramide). 
Gaucher disease is an autosomal recessive lysosomal glycolipid storage disease that results from a 
deficiency of acid β-glucosidase. The major natural substrate for this enzyme is GL-1, an 
intermediate metabolite in the synthesis and catabolism of more complex glycosphingolipids. 
Gaucher disease is characterized by lysosomal accumulation of GL-1 due to impaired GL-1 
hydrolysis secondary to the deficiency of the enzyme acid β-glucosidase. In patients with Gaucher 
disease, different tissues show increases in GL-1 concentration, leading to the main 
manifestations of the disease: anemia, thrombocytopenia, hepatosplenomegaly, skeletal disease, 
and neurological disease (1)(2)(3)(4)(5). 
The hallmark of Gaucher disease is the presence of lipid-engorged cells derived from the 
monocyte/macrophage lineage (Gaucher cell), which show a characteristic histological 
appearance and are distributed in tissues where macrophages reside (eg, liver, spleen, lung, and 
bone marrow). It is believed that the storage material within these Gaucher cells originates from 
phagocytosis of blood cells, while in neurons, the storage material is believed to originate from 
endogenous synthesis (5). 
Gaucher disease type 1 is rare, with an estimated frequency of 1 in 60,000 births in the general 
population (6). Although it is pan-ethnic, it is most commonly seen in the Ashkenazi Jewish 
population. Based on results of gene frequency for the two most common Ashkenazi Jewish 
mutations, the incidence of Gaucher disease in this population has been estimated to be 1 in 855 
births (5). 
Gaucher disease type 1 has a broad spectrum of severity (5). Thrombocytopenia is the most 
common hematological abnormality. Anemia is frequently mild, but occasionally quite severe. 
Some patients with severe enlargement of the spleen and liver have minimal skeletal involvement, 
while others with severe bone disease have minimal visceral disease. In other patients, visceral 
involvement and skeletal involvement are approximately equal in severity. The degree and type of 
bone involvement is markedly variable; however, loss of bone mass is very common, irrespective 
of the severity of the other manifestations of the disease. 
The accumulation of GL-1 and the more common clinical manifestations of the disease including 
anemia, thrombocytopenia, hepatosplenomegaly, and bone disease, can be treated by enzyme 
replacement therapy (ERT) with recombinant acid β-glucosidase (Cerezyme®, Genzyme, and 
VPRIV™, Shire) (7)(8)(9)(10)(11)(12). Elelyso (Pfizer, New York) was approved in the United 
States on 01 May 2012 as an ERT for the treatment of GD1. An alternative approach is the use of 
substrate reduction therapy using eliglustat, which acts by partially inhibiting the enzyme GL-1 
synthase. The goal of this approach is to reduce the synthesis of GL-1 to a level where the residual 
enzymatic activity of the mutant acid β-glucosidase, the enzyme deficient in Gaucher disease, can 
degrade GL-1, thus preventing its accumulation.

Certain disease affected tissues such as bone marrow and cortical bone are not optimally targeted 
with existing treatments (13). Because the biodistribution of a small molecule drug is likely to be 
more extensive than that of an enzyme, the substrate reduction therapy (SRT) approach is 
expected to provide benefit in tissues that are less accessible to ERT (14) and in cells that lack 
mannose receptors (15). In fact, preclinical studies with eliglustat demonstrated a wide 
distribution to tissues, including bone marrow. 
Bone involvement is a nearly universal and clinically relevant aspect of Gaucher disease, which 
affects both the osseous tissue and the bone marrow. As skeletal involvement can be severe and 
lead to significant morbidity, improvement in bone disease is important to patients as well as 
expert physicians (16) as evidenced by its inclusion as a key therapeutic goal for ERT (9) and in 
the schedule of recommended assessments in the ICGG Registry irrespective of treatment status. 
Some experts consider skeletal disease to be the most challenging aspect of the disease to treat. 
For example, Deegan et al. argue, having studied 100 patients with GD1 from 3 major referral 
centers in the United Kingdom, who had been treated with ERT, that Gaucher disease should no 
longer be viewed as a disorder with cytopenia causing bleeding, anemia and susceptibility to 
infection due to bone marrow infiltration and splenomegaly, but rather as a principally skeletal 
disorder with disabling effects on bone structure and metabolism, which once established are 
refractory to therapy (17). 
Eliglustat was approved by the US Food and Drug Administration (FDA) on 19 August 2014, the 
European Commission on 19 January 2015, the Health Canada on 21 April 2017, and the 
Australian Therapeutic Goods Administration (TGA) on 10 February 2015. Eliglustat marketing 
authorization applications are being assessed by other health authorities. 
 The efficacy of eliglustat in the treatment of adult patients with GD1 and posology in 
intermediate metabolizers (IMs) and extensive metabolizers (EMs) with a dose of 100 mg BID 
and poor metabolizers (PMs) with a dose of 100 mg QD is based on an extensive clinical 
development program and robust clinical results from 2 adequate, well controlled Phase 3 studies 
(ENGAGE and ENCORE), with supportive long term data from the Phase 2 study and ENGAGE 
and ENCORE extension periods (comprising data from 225 treated adult patients with GD1), and 
from extensive population based pharmacokinetic (PBPK) simulations.  
The benefits of eliglustat treatment include clinically meaningful reductions in organ volumes in 
treatment naïve patients and maintenance of organ volume stability in patients switching from 
ERT; increases in hematological values in treatment naïve patients and maintenance of 
hematological stability in patients switching from ERT (hemoglobin level and platelet count; 
improvement of bone disease in treatment naïve patients and maintenance of bone disease 
stability in patients switching from ERT (bone marrow infiltration and bone mineral density 
(BMD); a well defined mechanism of action and clinical pharmacology profile, and limited safety 
risk. These benefits have been demonstrated across a wide range of GD1 severity. 
The efficacy of eliglustat compares favorably to those of other marketed products for GD1. 
Eliglustat's safety profile is distinct from ERTs, with different common TEAEs, and is unlike 
miglustat, wherein high incidences of diarrhea, weight loss, and tremor result in a therapy with 
limited tolerability and acceptance by treating physicians and patients with GD patients. In 
addition to comparable efficacy to other approved ERTs and a favorable safety profile, eliglustat

has certain advantages over ERTs. Enzyme replacement therapy requires regular intravenous (IV) 
infusions (generally every 2 weeks) for the duration of a patient's lifetime, and some patients are 
unable or unwilling to receive ERT. 
Overall, eliglustat shows a favorable safety profile. Based on review of all available safety data, 
the adverse drug reaction profile of eliglustat is characterized by diarrhea, headache, arthralgia, 
flatulence, abdominal pain, fatigue, and nausea, each occurring in <6% of the treated population. 
Most reported adverse events (AEs) were mild in severity, and few patients discontinued due to 
AEs. The risks of greatest concern with eliglustat treatment have not been observed in clinical 
trials, but modeling suggests the possibility for clinically significant electrocardiogram (ECG) 
interval increases, which are mild in scope, in the setting of high eliglustat exposure. Also, since 
eliglustat is extensively metabolized by CYP2D6 and to a lesser extent by CYP3A4, the potential 
for drug-drug interactions that could lead to increases in eliglustat exposure exists.CYP2D6 
phenotype based dosing regimen allows managing potential for drug-drug interactions by 
restricting the patient population to PM, IM, and EM patients only, to ensure that patient exposure 
to eliglustat will remain within the therapeutic range.  
As seen in the Phase 2 study, ENGAGE, and ENCORE, and commensurate with the general 
population, more than 90% of GD1 patients are CYP2D6 PMs, IMs, or EMs, can be safely and 
effectively dosed at 100 mg daily (QD) (PMs) or 100 mg BID (IMs and EMs). The sufficiency of 
the IM and EM proposed dose is supported in particular by the Phase 2 study and ENGAGE, 
where most treatment naïve patients with IM and EM phenotypes were successfully treated at the 
100 mg BID dose.  
While patients of all phenotypes were successfully treated in clinical trials using dose titration, 
Sanofi Genzyme recommends an eliglustat dosing regimen comprised of 100 mg BID for IM and 
EM patients and 100 mg QD for PM patients in the post approval setting. 
During the clinical development program, a limited number of GD1 patients who were ultra rapid 
metabolizers (URMs) (1 in ENGAGE and 4 in ENCORE) were treated with eliglustat. The single 
URM patient in ENGAGE who received 100 mg BID was a nonresponder, suggesting that the 
100 mg dose may result in a maximum concentration (Cmax) too low to be effective for URMs. 
For indeterminate metabolizers, a phenotype cannot be predicted based on genotype, and 
therefore a dose cannot be recommended. Other treatment options are available for this minority 
of patients who would be ineligible for treatment with eliglustat. 
In vitro, eliglustat is a substrate of the efflux transporter P glycoprotein (P-gp). In addition, 
CYP2D6 and to a lesser degree cytochrome P450 3A4 (CYP3A4) are involved in eliglustat 
metabolism in vitro. Consequently, moderate and strong inhibitors of CYP2D6 and CYP3A 
increase its exposure, and potent cytochrome P450 3A (CYP3A) inducers decrease it. In addition, 
mild QTc interval prolongation is predicted to occur in a dose proportional fashion at eliglustat 
plasma concentrations beyond the therapeutic range. For these reasons, the restrictions on 
concomitant medications shown in Table 1 (Concomitant Medications Recommendations for Use 
with Eliglustat) have been proposed in product labeling for eliglustat. These restrictions will help 
ensure that exposure to eliglustat will remain within the range shown to be safe and effective in 
the clinical studies.

Previous clinical studies of eliglustat have provided evidence of its efficacy on bone 
manifestations. In Study GZGD00304, a Phase 2 open label study, 56% (n = 10) of the patients 
had reduced bone marrow infiltration of the femur as assessed by MRI after 4 years of treatment 
with eliglustat, and the mean lumbar spine BMD (g/cm2) increased by 9.9% (n = 15, p = 0.0176). 
The mean standard deviation (SD) lumbar spine BMD T-score was in the osteopenic range at 
baseline, -1.63 (1.07), and reached the normal range, -0.88 (1.26), after 4 years of treatment (p = 
0.0139). The mean (SD) lumbar spine BMD Z-score was -1.17 (0.92) at baseline and increased to 
-0.48 (1.07) after 4 years of treatment (p = 0.0044) ( GZGD00304: 48-month period clinical study 
report). 
In the Pivotal Phase 3 Study GZGD02507 where patients were randomized to eliglustat or 
placebo, the total bone marrow infiltration score, as assessed by MRI in lumbar spine and femur, 
decreased by a mean of 1.1 point after 9 months (n = 20) and 2.15 points after 18 months (n = 18) 
in the eliglustat group. The percentage of eliglustat treated patients with a clinically significant 
reduction of at least 2 points in the total bone marrow infiltration score increased from 26% 
(n = 5) after 9 months to 44% (n = 8) after 18 months. After 18 months of eliglustat treatment the 
mean (SD) lumbar spine BMD T score increased from -1.06 (0.82) (n = 17), within the osteopenic 
range, to -0.91 (0.88) (n = 15), within the normal range. Statistically significant reductions in 
plasma MIP-1 β, which is considered to be a biomarker of active bone disease, were observed 
with eliglustat compared with placebo (least squares [LS] mean treatment difference = -43.5%, 
p<0.0001). After 18 months and 30 months of treatment, BMB score had decreased by a mean of 
2.2 points (n=18) and 2.7 (n=15) points, respectively, for the patients originally randomized to 
eliglustat, compared to a mean decrease of 1 point (n=20) and 0.8 (n=16) in those originally 
randomized to placebo, and the percentage of eliglustat-treated patients with a significant 
reduction of at least 2 points in the total BMB score increased to 44% (n=8). After 18 and 30 
months of treatment with eliglustat in an open-label extension phase, the mean lumbar spine Z-
score in all patients increased from -1.208 (1.0546) at Baseline (n=38) to -0.949 (1.1447) (n=31). 
After 30 months and 4.5 years, the Z score further increased to -0.761 (1.0760) (n=31) and -0.478 
(0.7870) (n=9), respectively ( GZGD02507: 39-week [primary analysis period] and 78-week 
clinical study reports). 
In the Pivotal Phase 3 Study GZGD02607 where patients who had reached the Gaucher disease 
therapeutic goals (9) on ERT were randomized to eliglustat or ERT, lumbar spine BMD and total 
bone marrow infiltration score remained stable after 12 months, with similar mean changes in 
both treatment arms. Bone parameters remained stable after 24 months of eliglustat treatment. 
After completion of the primary analysis period (PAP), all patients who transitioned to the long-
term treatment period were treated with eliglustat. Individual disease parameters of spleen 
volume, liver volume, hemoglobin levels and platelet count remained stable through 4 years. With 
regard to BMD, lumbar spine and femur BMD T- and Z-scores were maintained within the 
normal range in patients treated with eliglustat for up to 4 years  (GZGD02607: 52-week [primary 
analysis period] and 104-week clinical study reports). 
In the 3rd Phase 3 study, EDGE GZGD03109, which evaluated the efficacy, safety, and 
pharmacokinetics (PK) of QD versus BID eliglustat in patients with GD1 who have demonstrated 
clinical stability on BID dosing of eliglustat, the majority of patients (83%) reached or maintained 
all 5 therapeutic goals (bone crises, hemoglobin, platelet count, spleen, and liver volume). Marked 
reductions in MIP1 β concentrations assessed as investigational biomarker of active bone disease

were observed after eliglustat treatment between 6 and 18 months (GZGD03109: 78-week clinical 
study report). 
More detailed efficacy and safety information is provided in the Investigator Brochure. 
The current study is an open label, interventional multicenter Phase 3b study to evaluate long term 
skeletal response to eliglustat in adult patients who successfully completed the Phase 2 or one of 
the Phase 3 studies (GZGD02507, GZGD02607, or GZGD03109). This study is considered an 
extension of these previous studies and will continue to evaluate long term safety of eliglustat and 
patients quality of life (SF-36).  
The main purpose of this extended treatment study is to evaluate long term skeletal response to 
eliglustat, i.e., change in bone disease after 2 additional years of treatment with eliglustat. The 
elements of bone disease to be evaluated include bone marrow infiltration,  BMD, lytic lesions, 
incidence of fractures and infarcts, bone biomarker levels (P1NP [bone formation], CTX and 
MIP1-β) and Gaucher disease assessments (mobility, bone crisis, and bone pain). These efficacy 
assessments will be collected at baseline and thereafter at twice-yearly (bone biomarkers, Gaucher 
disease assessments) and yearly (bone marrow infiltration, bone mineral density, lytic lesions, 
infarcts, osteonecrosis, fractures) intervals. 
As secondary endpoints the study will continue to evaluate patients’ quality of life (SF-36) and 
biomarkers of GD1 (chitotriosidase, plasma GL-1 and lyso-GL-1). Quality of life questionnaires 
will be administered and biomarkers of GD1 will be measured at baseline and twice-yearly 
thereafter. The safety of eliglustat (ie, incidence of [S]AEs), concomitant medications, changes 
from baseline in physical examinations, hematology will be monitored. Results of pregnancy 
testing for female patients of childbearing potential will be collected. Safety assessments will be 
performed at baseline and twice yearly. Continuous monitoring will be performed for (S)AEs and 
concomitant medications. 
Approximately four of the study centers that participated in the eliglustat Phase 2 or Phase 3 
studies will participate in this study. Participating physicians will enroll patients who successfully 
completed the Phase 2 or Phase 3 studies. The study will run for a minimum of 2 years and up to 
4 years, or until eliglustat is approved and available to patients through reimbursement or through 
the compassionate use (expanded access) program, whichever comes first. 
The study will enroll approximately 32 patients who will be treated with eliglustat and who have 
provided a signed informed consent. 
The study will include a screening period (Day -45 to -1) and a long-term treatment period up to 
4 years or until eliglustat is available to patients through reimbursement or through the 
compassionate use (expanded access) program, whichever comes first. After study completion 
patients will be encouraged to enroll in the ICGG Gaucher Registry. 
Cytochrome P450 (CYP) 2D6 IM, EM and URM patients will be treated with eliglustat 84 mg 
twice daily (BID). Cytochrome P450 (CYP) 2D6 PM patients will be treated with eliglustat 84 mg 
once daily (QD). Doses may have to be decreased when certain concomitant medications are 
administered (see Section 8.5.1.2).

STUDY DESIGN 
6.1 
DESCRIPTION OF THE PROTOCOL 
This is an open label, interventional, non-comparative, multicenter, multinational Phase 3b study 
to evaluate long term skeletal responses to eliglustat, eliglustat safety and effect on quality of life 
in adult patients who successfully completed one of the Phase 2 or Phase 3 studies in the eliglustat 
program. This study is considered an extension of these previous studies with the goal of 
obtaining longer term data. 
6.2 
DURATION OF STUDY PARTICIPATION 
6.2.1 Duration of study participation for each patient 
The duration of study participation for individual patients will be at least 2 years (unless early 
discontinuation occurs) and up to 4 years, or until commercial eliglustat is available to patients 
through reimbursement.  If after 4 years since the beginning of the study eliglustat is not approved 
and available to patients in participating country, patients in this country may continue to receive 
study treatment until eliglustat is available to patients through the compassionate use (expanded 
access) program or is approved and available through reimbursement, whichever comes first. 
The study will include  
• A screening period that can extend from Day -45 to Day-1,  
• A long-term treatment period  up to 4 years or until eliglustat is available to patients 
through reimbursement or through the compassionate use (expanded access) program, 
starting on Day 1 
After study completion, patients will be encouraged to enroll in the ICGG Gaucher Registry. 
6.2.2 Determination of end of clinical trial (all patients) 
The end of the study is defined as the last visit for the last patient. 
6.3 
INTERIM ANALYSIS 
No interim analysis is planned. 
6.4 
STUDY COMMITTEES 
The study data will not be reviewed by a Data Monitoring Committee. The IMP is approved for 
the treatment of Gaucher disease type 1 patients, the study population, by the FDA, EMA and

PATIENT DISCONTINUATION/WITHDRAWAL CRITERIA   
Patients are free to discontinue participation or withdraw consent from the study at any time, for 
any reason, and without prejudice to further treatment.  Patients who discontinue/withdraw from 
this study will receive treatment as deemed appropriate by their treating physician. 
A patient's participation in the study also may be discontinued at any time at the discretion of the 
Investigator or Sanofi Genzyme.  The Investigator will contact Sanofi Genzyme Clinical Study 
Director if a patient meets any of the withdrawal criteria.  The following may be justifiable 
reasons for the Investigator or Sanofi Genzyme to remove a patient from the study: 
• The patient was erroneously included in the study. 
• The patient is uncooperative, including failure to appear at one or more study visits, or is 
not compliant with taking study medication. 
• The patient develops an exclusion criterion or concurrent disease. 
• The patient receives other investigational product(s) during the course of this study. 
• The patient experiences an AE that is considered intolerable by the patient or investigator. 
• Sanofi Genzyme terminates the study. 
• If a female patient of childbearing potential has a positive pregnancy test  blood β-hCG or 
is lactating after first dosing with eliglustat in this study, the patient may remain in the 
study, but must suspend eliglustat till delivery and while breast feeding. The maximum 
duration of such an IMP suspension is 12 months. During the IMP suspension the patient 
must maintain compliance with all the other study requirements, except for the 
radiological examinations that are prohibited in pregnant women. 
If a patient meets at least 1 of the following criteria, the Investigator must notify the Sanofi 
Genzyme Clinical Study Director.  The Investigator and Sanofi Genzyme will review the clinical 
status of the patient and will determine if the patient should be withdrawn from the study.   
• The patient’s hemoglobin level falls below 80 g/L and remains below 80 g/L when the test 
is repeated within approximately 2 weeks. 
• The patient’s platelet count falls below 50 x 109/L and remains below 50 x 109/L when the 
test is repeated within approximately 2 weeks,  
• The patient experiences a clinically significant bleeding episode assessed by the 
Investigator as related to a low platelet count. 
• The patient experiences a decline in Gaucher disease status that, in the opinion of the 
Investigator, warrants discontinuation from the study (eg, repeated bone crises, clinically 
significant increases in liver or spleen volumes). 
Patient who discontinue or withdraw from participation in the study will be contacted in order to 
obtain information about the reason(s) for discontinuation/withdrawal and for collection of AEs, if 
any. The patient will be asked to return to the clinic to complete all study 
discontinuation/withdrawal assessments. The Investigator will describe the reason for

STUDY TREATMENTS 
8.1 
INVESTIGATIONAL MEDICINAL PRODUCT 
Eliglustat is supplied as 84 mg hard gelatin capsules for oral administration. Each 84 mg capsule 
contains 100 mg of eliglustat tartrate, which is equivalent to 84 mg of eliglustat free base. 
CYP2D6 IM, EM and URM patients will receive 84 mg BID. CYP2D6 PM will receive 84 mg 
QD. 
Given the rarity of the CYP2D6 URM phenotype, experience on treating these patients is limited. 
To make sure they are properly treated, additional monitoring will be performed in this patients 
(see Section 10.2.3.3). 
Eliglustat will be taken orally with water. 
For patients on BID dosing regimen, doses should be taken roughly every 12 hours (one capsule 
in the morning and one capsule in the evening). For patients on QD dosing regimen, doses should 
be taken at about the same time every day. 
Eliglustat absorption is not affected by food. Therefore, it can be taken with or without food at the 
convenience of the patient. 
8.1.1 IMP dose reduction 
Certain concomitant medications require a reduction in the dose of eliglustat (see Section 8.5.1.2). 
8.1.2 IMP temporary suspension 
Treatment with eliglustat should be suspended in patients who require short-term treatment with 
• A strong or moderate CYP2D6 inhibitor with a strong or moderate CYP3A inhibitor in 
CYP2D6 EMs and IMs. 
• A strong or moderate CYP3A inhibitor in CYP2D6 PMs. 
These medications can be used for up to 2 weeks at a time.  
All IMP temporary suspension should be documented in the IMP distribution CRF. 
Up to 2 episodes of eliglustat suspension are allowed per year. 
If these medications are required for longer treatment periods, the investigator should consult with 
the Clinical Study Director.

Page 34 
If a patient becomes pregnant during her participation in the study she may remain in the study, 
but must suspend eliglustat until delivery and while breast feeding. The maximum duration of 
such an IMP suspension is 12 months. During the IMP suspension the patient must maintain 
compliance with all the other study requirements, except for the radiological examinations that are 
prohibited in pregnant women. 
8.2 
PACKAGING AND LABELING 
Each bottle of IMP 84 mg capsules will contain 60 capsules and will be labeled with a single 
panel label. This will be provided in induction-sealed, high density polyethylene bottles with child 
resistant closure caps. Label text will include, at a minimum, the study protocol number, the 
contents of the bottle, lot number, use-by date, storage conditions and Genzyme name and 
address. Also included on the label will be any required cautionary statements and any other 
requirements, in accordance with regulations specific to each country where this study is 
conducted. 
Packaging is in accordance with the administration schedule. The content of the labeling is in 
accordance with the local regulatory specifications and requirements. 
8.3 
STORAGE CONDITIONS AND SHELF LIFE 
The IMP must be stored at a controlled room temperature of 20°C-25°C, with excursions 
permitted from 15°C - 30°C, in a secured location.  
Investigators or other authorized persons (eg, pharmacists) are responsible for storing the IMP in a 
secure and safe place in accordance with local regulations, labeling specifications, policies, and 
procedures.  
Control of IMP storage conditions, especially control of temperature (eg, controlled room 
temperature storage) and information on in-use stability and instructions for handling the IMP 
should be managed according to the rules provided by Sanofi Genzyme. 
8.4 
RESPONSIBILITIES 
The Investigator, the hospital pharmacist, or other personnel allowed to store and dispense the 
IMP will be responsible for ensuring that the IMP used in the clinical trial is securely maintained 
as specified by the Sponsor and in accordance with applicable regulatory requirements. 
All IMP will be dispensed in accordance with the Investigator's prescription and it is the 
Investigator's responsibility to ensure that an accurate record of IMP issued and returned is 
maintained. 
Any quality issue noticed with the receipt or use of an IMP (deficiency in condition, appearance, 
pertaining documentation, labeling, expiration date, etc.) should be promptly notified to 
Genzyme. Some deficiencies may be recorded through a complaint procedure.

A potential defect in the quality of IMP may be subject to initiation of a recall procedure by 
Genzyme. In this case, the Investigator will be responsible for promptly addressing any request 
made by Genzyme, in order to recall IMP and eliminate potential hazards. 
Under no circumstances will the Investigator supply IMP to a third party, allow the IMP to be 
used other than as directed by this clinical trial protocol, or dispose of IMP in any other manner. 
8.4.1 Treatment accountability and compliance 
At each visit the Investigator or his/her delegate will question patients to assess treatment 
compliance and will remind patient of the importance of excellent treatment compliance. 
IMP accountability: 
• Treatment units are returned by the patient at each visit; 
• The Investigator or delegate records the dosing information on the appropriate page(s) of 
the CRF; 
• The monitor in charge of the study then checks the CRF data by comparing them with the 
IMP that he/she has retrieved and the treatment log forms. 
8.4.2 Return and/or destruction of treatments 
All used, partially-used or unused treatment bottles will be retrieved from each patient at each site 
visit. A detailed treatment log of the patient returned bottles (used, partially used, or unused) to 
the site will be established.  Any IMP destroyed on site or returned to Genzyme will be 
documented in the treatment log and associated Sponsor form(s).  The Investigator will not 
destroy any IMP unless Genzyme provides written authorization. Please refer to the study 
Pharmacy Manual for further details.   
8.5 
CONCOMITANT MEDICATION 
Patients will be monitored continuously for changes in the use of concomitant medications 
(introduction of new medications and changes in the dose or regimen of preexisting medications).  
Patients will be instructed to report to the Investigator any changes in concomitant medications 
before these changes are made, or, in the case of changes made in emergency situations, as soon 
as possible.

8.5.1 INTERACTION WITH OTHER MEDICINAL PRODUCTS AND OTHER FORMS OF 
INTERACTION  
8.5.1.1 ANTIARRHYTHMICS 
Because eliglustat is predicted to cause mild increases in ECG intervals (PR, QTc, and QRS) at 
substantially elevated eliglustat plasma concentrations, use of eliglustat is prohibited in 
combination with Class IA and Class III antiarrhythmic medications. Patients who require long 
term treatment with any of these medications should be removed from the study. 
8.5.1.2 EFFECT OF OTHER DRUGS ON ELIGLUSTAT 
Eliglustat is metabolized primarily by CYP2D6 and to a lesser extent by CYP3A4. Concomitant 
administration of substances affecting CYP2D6 or CYP3A4 activity (ie, CYP2D6/CYP3A 
inhibitors and CYP3A strong inducer) may alter Genz-99067 plasma concentrations. Grapefruit 
products contain one or more components that inhibit CYP3A and can increase plasma 
concentrations of eliglustat. Grapefruit and grapefruit products including grapefruit juice, but not 
grapefruit seeds, are prohibited at any time during the study.  
Table 1 provides an overview of allowed and prohibited inhibitors and inducers for chronic use, 
as determined by the patient’s CYP2D6 phenotype.

8.5.1.3 EFFECT OF ELIGLUSTAT ON OTHER DRUGS 
In vivo eliglustat was found to be an inhibitor of P-glycoprotein (P-gp; 1.5-fold increase in 
digoxin area under the plasma concentration versus time curve from 0 to the real time 
corresponding to the last concentration above the lower limit of quantification) and an inhibitor of 
CYP2D6 (2.1-fold in metoprolol area under the plasma concentration versus time curve 
extrapolated to infinity [area under the concentration-time curve (AUC)]), consistent with in vitro 
data showing eliglustat to be an inhibitor of CYP2D6 and of P-gp. Eliglustat may increase the 
plasma concentration of those substances and should be used with caution in combination with a 
P-gp or a CYP2D6 substrate. Lower doses of such drugs may be required.

ASSESSMENT OF INVESTIGATIONAL MEDICINAL PRODUCT 
9.1 
PRIMARY ENDPOINT 
The main purpose of this extended treatment study is to evaluate long term skeletal responses to 
eliglustat after 2 additional years of treatment with eliglustat.  Five common skeletal 
manifestations of Gaucher disease will be assessed:  
1) Mobility, bone pain and bone crisis, as assessed by the Gaucher Disease clinical assessments; 
2) bone marrow infiltration; 3) BMD; 4) Lytic lesions, osteonecrosis, fractures and infarcts; 5) 
bone biomarkers  
9.1.1 Gaucher disease clinical assessments (mobility, bone pain, bone crisis). 
Patients will be asked to rate  
• Current mobility  
- 
Unrestricted mobility 
- 
Walks with difficulty 
- 
Walks with orthopedic aid 
- 
Requires wheelchair 
- 
Bedridden  
• Level of bone pain during the last 4 weeks as 
- 
None 
- 
Very mild 
- 
Mild 
- 
Moderate 
- 
Severe 
- 
Extreme 
• In addition, investigators will report the number of bone crisis since the previous 
assessment. Bone crisis is defined as pain with acute onset, which requires immobilization 
of the affected area, narcotics for relief of pain, and may be accompanied by one or more 
of the following: periosteal elevation, elevated white blood cell count, fever, or 
debilitation of >3 days.   
Gaucher disease clinical assessments will be performed at screening and then yearly.

9.1.2 Bone marrow infiltration  
Will be assessed on sagittal T1 and T2 weighted MRI views of the lumbar spine and coronal T1 
and T2 weighted MRI views of the entire bilateral femurs. A categorical bone marrow infiltration 
score will be calculated based on the amount of fat in the basivertebral vein region and the T1 and 
the T2 signals (18).  
Bone marrow infiltration will be measured at screening and then yearly. 
Bone MRI will be read locally and centrally. The central reads will be used for analysis. 
9.1.3 Bone mineral density (BMD)  
Will be measured by DXA of both hips and the lumbar spine. T and Z scores, and bone mineral 
densities will be provided by the DXA report. 
Bone mineral density will be measured at screening and then yearly. 
9.1.4 Lytic lesions, osteonecrosis, fractures and infarcts 
Lytic lesions, osteonecrosis, infarcts and fractures will be assessed on bone MRI and bone X-Ray.  
9.1.5 Bone biomarkers 
Will include 
• Total procollagen type 1 N-terminal propeptide (P1NP), a marker of bone formation 
• C-terminal telopeptide of type 1 collagen (CTx), a marker of bone resorption  
• MIP 1 β 
These biomarkers will be measured at baseline and then every 6 months. 
These markers will be measured by a central laboratory. 
Results of centrally read assessments will be available to Investigators during or after the study 
depending on the assessment. 
9.2 
SECONDARY ENDPOINT(S) 
9.2.1 Efficacy endpoints 
Blood levels of biomarkers of GD1 (chitotriosidase, plasma GL-1 and lyso-GL-1) will be 
evaluated at baseline and twice yearly. These markers will be measured in a central laboratory. 
Measured values as well as absolute and percent changes from study baseline and eliglustat 
baseline will be summarized.

9.2.2 Safety endpoints 
9.2.2.1 Adverse events 
Refer to Section 10.5 to 10.7 for details. 
Continuous monitoring will be performed for (S)AEs and concomitant medications.  
Results of pregnancy testing for female patients of childbearing potential will be collected. 
9.2.2.2 Laboratory safety variables 
The clinical laboratory data consist of hematology analyses. These analyses will be conducted by 
local laboratories at each site. Clinical laboratory values will be analyzed after conversion into 
standard international units. International units will be used in all listings and tables. 
9.2.2.3 Physical examination 
Complete physical exam will be performed including complete neurological exam with ocular 
motility test. 
9.2.3 Patient Reported Outcomes  
Patients’ quality of life (Short Form-36 Health survey) will be evaluated at baseline and twice-
yearly.  
The SF-36 survey is a self-reported questionnaire used to measure a patient’s profile of functional 
health and well-being as well as psychometrically-based physical and mental health summary 
measures. The SF-36 is a multi-purpose, short-form health survey with 36 questions. Accordingly, 
the SF-36 has proven useful in surveys of general and specific populations, comparing the relative 
burden of diseases, and in differentiating the health benefits produced by a wide range of different 
treatments (19). A recall period of 1 week will be used. 
9.3 
PHARMACOKINETICS 
Although PK samples are not scheduled, unscheduled PK samples may be collected in individual 
cases after discussion between the investigator and Genzyme. 
9.3.1 Sampling time 
Sampling times will be decided in each case after discussion between the investigator and 
Genzyme.

testing  may be used for other research purposes (excluding genetic analysis) related to lysosomal 
storage disorders  than those defined in the present protocol.  
These other research analyses will help to understand either disease subtypes or drug response, or 
to develop and/or validate a bioassay method, or to identify new drug targets or biomarkers.  
These samples will remain labelled with the same identifiers than the one used during the study 
(ie, subject ID). They will be transferred to a Sponsor site (or a subcontractor site), which can be 
located outside of the country where the study is conducted. Genzyme has included safeguards for 
protecting subject confidentiality and personal data (see Section 14.3 and Section 14.5). 
9.5 
APPROPRIATENESS OF MEASUREMENTS  
9.5.1 Primary endpoint 
The primary endpoint, bone disease, will be assessed using measurements that have been 
validated for Gaucher disease or for other more common bone conditions. 
Gaucher disease clinical assessments (mobility, bone pain and bone crisis) are established clinical 
parameters of bone lesions in Gaucher disease (8). 
Magnetic Resonance Imaging is an established procedure to evaluate bone marrow not only for 
Gaucher disease, but also in oncology (20). It avoids the exposure to ionizing radiations observed 
with computerized tomography. A semi-quantitative method of measuring bone marrow 
infiltration by MRI has been developed and validated (18). It requires only standard equipment. 
Therefore, it can be implemented in study sites worldwide. Central reading of the images by 
trained readers will increase the quality and decrease the variability of the results.

Bone MRI also allows detecting lytic lesions, osteonecrosis, infarction and fractures. 
Bone MRI will be performed yearly, a standard frequency in patients who are expected to be 
stable after multiple years of eliglustat treatment. 
Dual-energy X-ray absorptiometry is the gold standard to measure BMD. A yearly frequency has 
been established as the time necessary to see significant changes in BMD. 
Femur and spine X-Ray will serve mainly as references for additional follow up of the patients 
once they have left the study, when MRI may not been widely available or traditionally used to 
follow patients. 
Bone biomarkers 
Total procollagen type 1 N-terminal propeptide (P1NP), a marker of bone formation, and 
C-terminal telopeptide of type 1 collagen (CTx), a marker of bone resorption, have been 
recommended as reference markers of fracture risk assessment in age related osteoporosis by a 
working group of the International Osteoporosis Foundation and the International Federation of 
Clinical Chemistry and Laboratory Medicine (21). 
MIP1β has been shown to display moderate sensitivity and specificity to detect osteonecrosis in 
Gaucher disease (22). 
9.5.2 Secondary endpoints 
The use of patient reported outcomes as provided by quality of life questionnaires is encouraged 
by health authorities and entities paying for health care. In the absence of a validated tool to 
specifically assess disease burden in Gaucher disease type I patients, SF-36 has been selected 
because it is validated in multiple diseases and is available in multiple languages. 
Chitotriosidase is an established biomarker in Gaucher disease and is thought to reflect the total 
body burden in Gaucher cells, except in patients who carry 1 or 2 null allele. Its level is related to 
the amount of GL-1, the substrate that accumulates as a result of the decreased activity of mutated 
acid β-glucosidase. Its level is elevated in untreated patients, especially the more severely affected 
ones, and decreases when patients improve on ERT or SRT (see for example (23)(24).

STUDY PROCEDURES 
10.1 
GENERAL CONSIDERATIONS  
Imaging: 
Central reading will be set up for liver and spleen MRI and bone imaging. All imaging procedures 
will be performed locally and the images copied onto an electronic support and shipped to a 
central facility for interpretation. Interpretation by local specialists will be used for the usual care 
of the patients, but its results will not be entered in the clinical database. 
Urine Pregnancy test: 
In addition to the blood pregnancy tests performed at every visit, prior to performing any 
radiologic study assessment (imaging), a urine pregnancy test must be performed and the result 
reviewed by the radiologist/technician who will document that the patient has a negative 
pregnancy test result by signing, dating, and noting the time of the review on the pregnancy result 
report. In case of a positive pregnancy test, radiologic study assessments will not be performed.  
In addition female patients must perform a urine pregnancy test at home every 4 weeks while 
receiving eliglustat treatment. 
Any positive urine pregnancy test will be verified with a blood pregnancy test. All pregnancy tests 
results must be documented in the patient file. 
Laboratory tests: 
All laboratory tests will be done at the local laboratory at the exception of those for biomarkers, 
which will be done in central laboratories. 
10.2 
VISIT SCHEDULE 
All visits will be outpatient visits. However, for patients who have to travel long distances to 
come to a site, overnight stay in the hospital or in a lodging facility nearby may be used. 
10.2.1 Screening period 
Screening will be performed between 45 and 1 day before Day 1 of the study. Screening can be 
performed at the time of the EOS visit of the previous study the patient was enrolled in. 
Final GZGD00304, GZGD02507, GZGD02607 and GZGD03109 study assessments may serve as 
entry evaluation for this study if performed less than 3 month for laboratory testing, 1 year for 
bone imaging and 6 months for other assessments.

However, safety (S)AE, concomitant medication and prior medication history, physical 
examinations, HIV antibody, hepatitis C antibody, or hepatitis B surface antigen, blood pregnancy 
test, height will have to be performed in all cases.  
Patients will be assigned a unique ID number. This new ID number as well as the number of the 
previous study the patient was enrolled in and his/her ID number in that study will appear in the 
clinical database. 
For some assessments it will be possible to use results from the end of study visit of the previous 
eliglustat study the patient was enrolled in. For others they will need to be performed anew. See 
detail below. 
The screening procedures do not have to be performed over 2 visits. Scheduling will be based on 
investigator, patient and resources availability. 
After completion of all the screening assessments, the investigator will review their results to 
confirm that each patient meets all the inclusion criteria and none of the exclusion criteria before 
scheduling the patient for the Day 1 visit. 
10.2.1.1 Clinical information 
• Demographic data will be entered in the corresponding CRF. 
• Previous medical/surgical history entered in the CRF of the previous study should not be 
re-entered in the Medical history CRF of this study, but will be used in the analysis of this 
study.  
• The following categories of medico/surgical events are considered part of the 
medical/surgical history of the patient and should be entered in the Medical/surgical 
history CRF: 
- 
AEs started during the previous study, which are closed at the time of the screening 
visit and are still considered clinically significant by the investigator at the time of the 
screening visit. 
- 
Medical/surgical events started after the follow-up phone call of the previous study 
and before the ICF signing in the current study, whether ongoing or closed, if they are 
considered clinically significant by the investigator.  
- 
Clinically significant abnormal laboratory test results at Visits 1 and 2 (Screening 
period) 
• AEs started during the previous study, which are ongoing at the time of the screening visit 
should be entered in the AE CRF regardless of whether the patient had a gap in eliglustat 
treatment after the end of the previous study, or the end of study visit of the previous study 
and the screening visit of this study are concomitant. 
• Concomitant medications: Any concomitant medication the patient is taking at the time of 
screening or took during the previous 30 days. This should include eliglustat if the last 
dose of eliglustat in the previous study was taken 30 days or less prior to the screening

to hospital records, clinic and office charts, study-specific source document worksheets, phone 
logs, memoranda, evaluation checklists, laboratory requisitions and reports, MRI, DXA, X-Ray 
reports, local laboratory reports, medication dispensing reports and any other documents 
regarding the patient.  
10.4 
HANDLING OF PATIENT TEMPORARY OR PERMANENT TREATMENT 
DISCONTINUATION AND OF PATIENT STUDY DISCONTINUATION  
The IMP should be continued whenever possible. In case the IMP is discontinued, it should be 
determined whether the discontinuation can be made temporarily; permanent IMP discontinuation 
should be a last resort. Any IMP discontinuation should be fully documented in the patient’s 
(electronic

medical file and the IMP Accountability CRF. In any case, the patient should remain in the study 
as long as possible. 
10.4.1 Temporary treatment discontinuation with investigational medicinal product(s) 
Temporary treatment discontinuation may be considered by the Investigator because of suspected 
AEs. Reinitiating of treatment with the IMP will be done under close and appropriate clinical/and 
or laboratory monitoring once the Investigator will have considered according to his/her best 
medical judgment that the responsibility of the IMP(s) in the occurrence of the concerned event 
was unlikely and if the selection criteria for the study are still met, and after discussion with 
Genzyme (refer to Section 7.1  and 7.2). 
For all temporary treatment discontinuations, duration should be recorded by the Investigator in 
the IMP administration CRF.  
If a patient becomes pregnant during her participation in the study she may remain in the study, 
but must suspend the IMP till delivery and while breast feeding. The maximum duration of such 
an IMP suspension is 12 months. During the IMP suspension the patient must maintain 
compliance with all the other study requirements, except for the radiological examinations that are 
prohibited in pregnant women. 
10.4.2 Permanent treatment discontinuation with investigational medicinal product(s) 
Permanent treatment discontinuation is any treatment discontinuation associated with the 
definitive decision from the Investigator or the patient not to re-expose the patient to the IMP 
during the duration of the study. 
10.4.3 Criteria for permanent treatment discontinuation 
The patients may withdraw from treatment with the IMP if they decide to do so, at any time and 
irrespective of the reason, or this may be the Investigator’s decision. All efforts should be made to 
document the reasons for treatment discontinuation and this should be documented in the e-CRF. 
The use of eliglustat is prohibited in combination with Class IA and Class III antiarrhythmic 
medications. See Section 8.5.1.1 for detail. 
Patients requiring medications incompatible with eliglustat because of drug-drug interaction for 
longer than 2 weeks should be discontinued from the study. See Section 8.5.1.2 for detail. 
Handling of patients after permanent treatment discontinuation 
Patients will be followed-up according to the study procedures as specified in this protocol up to 
the scheduled date of study completion, or up to recovery or stabilization of any AE to be 
followed-up, whichever comes last, unless the patient is lost to follow up. 
If possible, and after the permanent discontinuation of treatment, the patients will be assessed 
using the procedure normally planned for the last visit at study completion or patient 
discontinuation/withdrawal.

All cases of permanent treatment discontinuation should be recorded by the Investigator in the 
appropriate pages of the CRF when considered as confirmed. 
10.4.4 Procedure and consequence for patient withdrawal from study. 
The patients may withdraw from the study before study completion if they decide to do so, at any 
time and irrespective of the reason. 
If possible, the patients are assessed using the procedure normally planned for the visit at study 
completion or patient discontinuation/withdrawal. 
For patients who fail to return to the site, the Investigator should make the best effort to recontact 
the patient, and to determine his/her health status, including at least his/her vital status. Attempts 
to contact such patients must be documented in the patient’s records (eg, times and dates of 
attempted telephone contact, receipt for sending a registered letter). 
The statistical analysis plan will specify how these patients lost to follow-up for their primary 
endpoints will be considered. 
Patients who have withdrawn from the study cannot be enrolled again in the study. Their 
inclusion and treatment numbers must not be reused.  
10.5 
OBLIGATION OF THE INVESTIGATOR REGARDING SAFETY REPORTING 
10.5.1 Definitions of adverse events  
10.5.1.1 Adverse event 
An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation 
patient administered a pharmaceutical product and which does not necessarily have to have a 
causal relationship with this treatment. 
10.5.1.2 Serious adverse event 
A serious adverse event (SAE) is any untoward medical occurrence that at any dose: 
• Results in death, or 
• Is life-threatening, or 
 
Note: The term “life-threatening” in the definition of “serious” refers to an event in which 
 
the patient was at risk of death at the time of the event; it does not refer to an event which 
 
hypothetically might have caused death if it were more severe. 
• Requires inpatient hospitalization or prolongation of existing hospitalization, or 
• Results in persistent or significant disability/incapacity, or 
• Is a congenital anomaly/birth defect 
(electronic

EFC13781 
Version number: 1 
Property of the Sanofi Group - strictly confidential 
Page 50 
• Is a medically important event 
Medical and scientific judgment should be exercised in deciding whether expedited 
reporting is appropriate in other situations, such as important medical events that may not 
be immediately life-threatening or result in death or hospitalization but may jeopardize the 
patient or may require medical or surgical intervention (ie, specific measures or corrective 
treatment) to prevent one of the other outcomes listed in the definition above. 
Note: The following list of medically important events is intended to serve as a guideline for 
determining which condition has to be considered as a medically important event. The list is 
not intended to be exhaustive nor indicative of expected AEs: 
• Any reason for intensive treatment in an emergency room or at home 
• Cancers diagnosed during the study or aggravated during the study (only if judged 
unusual/significant by the Investigators in oncology studies) 
• Chronic neurodegenerative diseases (newly diagnosed) or aggravated during the study 
(only if judged unusual/significant by the Investigators in studies assessing specifically the 
effect of a study drug on these diseases). 
10.5.1.3 Adverse event of special interest 
An adverse event of special interest (AESI) is an AE (serious or non-serious) of scientific and 
medical concern specific to Genzyme product or program, for which ongoing monitoring and 
immediate notification by the Investigator to Genzyme is required. Such events may require 
further investigation in order to characterize and understand them. Adverse events of special 
interest may be added or removed during a study by protocol amendment. 
For this study the following AEs will be considered as AESI and should be reported as such to 
GPE: 
• Clinically significant cardiac arrhythmias detected by ECG or Holter monitoring that do 
not meet criteria for an SAE. 
• Syncope from any cause.  
• Pregnancy of a female patient as well as pregnancy occurring in a female partner of a male 
patient. 
• Pregnancy will be qualified as an SAE only if it fulfills one of the seriousness criteria (see 
Section 10.5.1.2). 
In the event of pregnancy in a female patient, IMP should be suspended. See Section 10.4.3 for 
detail. 
Female patients will be instructed to notify the investigator immediately if they discover they are 
pregnant. Pregnant female patients will be discontinued from the study.  
Male patients will be instructed to notify the investigator immediately if they discover that their 
sexual partner is pregnant.

Page 51 
If the investigator learns of a report of pregnancy at any time after signing the informed consent, 
the investigator should follow the instructions in Section 10.5.4 to contact the sponsor within 
24 hours; however, the investigator will be asked to complete the Pregnancy forms rather than 
SAE forms. The patient will be followed until the outcome of the pregnancy is known (eg, live 
birth or stillbirth). The investigator will be responsible for this follow-up. 
Follow-up of the pregnancy in a female patient or in a female partner of a male patient is 
mandatory until the pregnancy outcome has been determined, unless prohibited by local 
regulations. 
• Symptomatic overdose (serious or non-serious) with IMP 
- 
A symptomatic overdose (accidental or intentional) with the IMP is an event suspected 
by the Investigator or spontaneously notified by the patient (not based on systematic 
pills count) and defined as administration of a quantity of IMP per administration or 
per day, which is above the maximum recommended dose according to the authorized 
product information  
If overdose is suspected, the patient will be asked to suspend the IMP immediately and 
come back to the site for appropriate monitoring. 
Asymptomatic overdose has to be reported as a standard AE. 
10.5.2 General guidelines for reporting adverse events 
• Patients for whom the screening visit of this study is done at the same time as the EOS 
visit of the previous eliglustat study they were enrolled in, the safety follow-up phone 
scheduled 30-37 days after the EOS visit of the previous study will not be done. Instead, 
these patients will be monitored according to the standard safety procedures of this study. 
The Ethics Committees (and Local Health Autority, if required) at the affected sites will 
be notified.  
• All AEs, regardless of seriousness or relationship to IMP, spanning from the signature of 
the informed consent form until the end of study visit, or the last IMP administration for 
patient with early termination, are to be recorded on the corresponding page(s) or screen(s) 
of the CRF.  
• The following categories of medico/surgical events are considered part of the 
medical/surgical history of the patient and should be entered in the Medical/surgical 
history CRF: 
- 
AEs started during the previous study, which are closed at the time of the screening 
visit and are still considered clinically significant by the investigator at the time of the 
screening visit. 
- 
Medical/surgical events started after the follow-up phone call of the previous study 
and before the ICF signing in the current study, whether ongoing or closed, if they are 
considered clinically significant by the investigator.  
• AEs started during the previous study, which are ongoing at the time of the screening visit 
should be entered in the AE CRF regardless of whether the patient had a gap in eliglustat 
(electronic

Page 52 
treatment after the end of the previous study, or the end of study visit of the previous study 
and the screening visit of this study are concomitant. 
• Whenever possible, diagnosis or single syndrome should be reported instead of symptoms. 
The Investigator should specify the date of onset, intensity, action taken with respect to 
IMP, corrective treatment/therapy given, additional investigations performed, outcome, 
and his/her opinion as to whether there is a reasonable possibility that the AE was caused 
by the IMP or by the study procedure(s).  
• The Investigator should take appropriate measures to follow all AEs until clinical recovery 
is complete and laboratory results have returned to normal, or until progression has been 
stabilized, or until death, in order to ensure the safety of the patients. This may imply that 
observations will continue beyond the last planned visit per protocol, and that additional 
investigations may be requested by the monitoring team up to as noticed by Genzyme. 
Patients who experience an ongoing SAE or an AESI at the prespecified study end-date, 
should be monitored until follow-up is no longer considered medically necessary or the 
patient is lost to follow-up.  
• When treatment is prematurely discontinued, the patient’s observations will continue until 
the end of the study visit as defined by the protocol for that patient, unless the patient is 
lost to follow up. 
• Clinically significant laboratory abnormalities after Visit 3 (Day 1) are to be recorded as 
AEs only if:  
- 
Symptomatic and/or  
- 
Requiring either corrective treatment or consultation, and/or  
- 
Leading to IMP discontinuation or modification of dosing, and/or  
- 
Fulfilling a seriousness criterion, and/or  
- 
Defined as an AESI 
10.5.3 Instructions for reporting serious adverse events 
In the case of occurrence of an SAE, the Investigator must immediately: 
• ENTER (within 24 hours) the information related to the SAE in the appropriate screens of 
the e-CRF; the system will automatically send a notification to the monitoring team after 
approval of the Investigator within the e-CRF or after a standard delay. 
• SEND (preferably by fax or e-mail) a photocopy of all examinations carried out and the 
dates on which these examinations were performed, to the representative of the monitoring 
team whose name, fax number, and email address appear on the clinical trial protocol. 
Care should be taken to ensure that the patient's identity is protected and the patient's 
identifiers in the clinical trial are properly mentioned on any copy of a source document 
provided to Genzyme. For laboratory results, include the laboratory normal ranges. 
• All further data updates should be recorded in the e-CRF as appropriate, and further 
documentation as well as additional information (for laboratory data, concomitant

medications, patient status, etc.) should be sent (by fax or e-mail) to the monitoring team 
within 24 hours of knowledge of the SAE. In addition, every effort should be made to 
further document any SAE that is fatal or life threatening within a week (7 days) of the 
initial notification. 
• A back-up plan (using a paper CRF process) is available and should be used when the 
e-CRF system does not work. 
Any SAE brought to the attention of the Investigator at any time after the end of the study for the 
patient and considered by him/her to be caused by the IMP with a reasonable possibility, should 
be reported to GPE. 
10.5.4 Guidelines for reporting adverse events of special interest   
For AESIs, Genzyme must be informed immediately (ie, within 24 hours), as per SAE notification 
guidelines described in Section 10.5.3, even if not fulfilling a seriousness criterion, using the 
corresponding pages of the CRF (to be sent) or screens in the e-CRF. Instructions for AE 
reporting are summarized in Table 2.

STATISTICAL CONSIDERATIONS 
11.1 
DETERMINATION OF SAMPLE SIZE 
This study will enroll all eligible patients having completed one of the Phase 2 or Phase 3 trials 
(approximately 32 patients). 
This is an extension study. No sample size calculation has been performed. The patients who will 
be enrolled have already been receiving the IMP for approximately 4 to 8 years prior to the start 
of the study. The aim of the study is to continue collecting long term data on the efficacy and 
safety of the IMP. 
11.2 
DISPOSITION OF PATIENTS 
Screened patients are defined as any patient who met the study criteria and signed the informed 
consent.  
11.3 
ANALYSIS POPULATIONS 
11.3.1 Efficacy populations 
Primary and secondary efficacy will be evaluated in the Full Analysis Set population (FAS) 
defined as all patients enrolled who receive at least 1 dose of eliglustat treatment in this study. 
11.3.2 Safety population 
Safety analyses will be performed on the Safety Set, which is equivalent to the FAS for this study. 
11.3.3 Pharmacokinetic population 
Pharmacokinetic (PK) population: a subset of safety population containing patients who have at 
least one PK sample taken. Patients will be analyzed in the treatment group corresponding to 
those defined in the safety population. 
11.4 
STATISTICAL METHODS 
All endpoints will be summarized descriptively; no hypothesis testing will be performed. 
Descriptive statistics include those for continuous (n, mean, median, minimum, maximum), 
categorical (n, percent), cumulative incidence (n, percent) or incidence rate (n/year) outcomes, as 
appropriate. Calculations and summaries will include all non-missing data at a given time point, 
imputation will not be performed.

Analysis will be performed on safety and efficacy endpoints at 2 points in this study: 
• After the last patient enrolled has completed 2 years of treatment (two-year analysis 
period)  
• When the study is complete    
For the PAP, response will be calculated both in reference to study entry (study period) and to 
first eliglustat treatment (eliglustat treatment period).  Because patients will enter this study 
having been treated with eliglustat for various durations, two baselines will be used:  
• Study baseline, defined as status at study entry; and  
• Eliglustat baseline, defined at status at first dose of eliglustat in the previous Phase 2 or 
Phase 3 study.   
In reference to the study period, skeletal response will be evaluated for all patients at the 2 year 
point by measured values (eg, category of bone pain, or bone density value in g/cm2) and changes 
from baseline (eg, shift in category of bone pain or absolute and percent change from baseline in 
BMD g/cm2 or incidence over 2 years, as appropriate).   
In reference to the period of eliglustat treatment, skeletal response will be evaluated 2 years after 
study entry, but results will be grouped by duration of eliglustat treatment at the time of analysis.  
The actual groupings will depend on the distribution of treatment duration at the time of analysis, 
eg, 6 yr., 7 yr., 8 yr. or 6-8 yr., 8-10 yr. 
When the study has completed, summaries will be performed for both the total on-study period, 
and the eliglustat treatment period, as described above.   
11.4.1 Extent of study treatment exposure and compliance 
The extent of study treatment exposure and compliance will be assessed and summarized by 
actual treatment received within the safety population. 
Duration of IMP exposure is defined as:  last dose date – first dose date + 1 day, regardless of 
unplanned intermittent discontinuations.   
A given period of administration will be considered noncompliant if the patient takes less than 
90% or more than 105% of the planned dose of treatment as required by the protocol.  No 
imputation will be made for patients with missing or incomplete data. Treatment compliance, 
above-planned and under-planned dosing percentages will be summarized descriptively (N, Mean, 
SD, Median, Min, and Max). The percentage of patients with compliance categorized as <80%, 
80%-90%, 90%-105%, >105% will be summarized.

Shifts in category from study and eliglustat baseline will be summarized.  
1. BMD: Bone mineral density in (g/cm2), as well as T and Z scores, will be summarized by 
time point as well as absolute and percent changes from study and eliglustat baseline.  
2. Lytic lesions, fractures, infarctions and osteonecrosis. Incidence of new or worsening lytic 
lesions, new or worsening AVN, new or worsening infarctions and new fractures will be 
summarized at the 2 year and end of study time points. Annual incidence rates may also be 
calculated and summarized.   
3. Bone biomarkers: Levels of P1NP, CTx and MIP 1 β, as well as absolute and percent 
changes from study or eliglustat baseline will be summarized.  
11.4.2.2 Analyses of secondary efficacy endpoints 
Biomarker: Biomarkers will be summarized as measured values, absolute and percent change 
from eliglustat and study baseline. 
11.4.3 Analyses of safety data 
Adverse experience will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA) Version 18.0 or higher; all adverse experiences will be summarized by body system 
and MedDRA preferred term overall, by relationship and severity and seriousness. All deaths will 
be summarized.

time point.  Additionally, the change from study baseline and/or eliglustat baseline, as 
appropriate, may be summarized. Concomitant medications will be reported. 
Observation period  
The observation of safety data will be as follows:  
• Screening is from signed informed consent to the day before the 1st dose of IMP is 
administered.     
• TEAE observation period is from first to last dose of IMP in this study. Patients with an 
SAE or AESI should be followed until resolution or when follow-up is no longer 
considered medically necessary, or the patient is lost to follow-up. 
All safety analyses will be performed on the Safety population using the following common rules: 
The baseline value is defined generally as the last available value before first dose of IMP in this 
study.   
Adverse event incidence tables will present by system organ class (SOC) (sorted by 
internationally agreed order), preferred term (PT) sorted by decreasing frequency for each 
treatment group, the number (n) and percentage (%) of patients experiencing an AE.  Multiple 
occurrences of the same event in the same patient will be counted only once in the tables within a 
treatment Phase. The denominator for computation of percentages is the safety population within 
each treatment group. 
AE incidence tables for the AESIs below will be generated. 
• Clinically significant cardiac arrhythmias detected by ECG or Holter monitoring that do 
not meet criteria for an SAE. 
• Syncope from any cause. 
Death: The following deaths summaries will be generated: 
• Number (%) of patients who died and reasons for death if collected in death report form 
summarized on the safety population 
• All AEs leading to death (death as an outcome on the AE CRF page as reported by the 
Investigator), by primary SOC and PT, showing number (%) of patients sorted by 
internationally agreed order of SOC and alphabetic order of PT  
• TEAE leading to death (death as an outcome on the AE CRF page as reported by the 
Investigator) by primary SOC and PT showing number (%) of patients sorted by 
internationally agreed order of SOC and alphabetic order of PT.

without agreement by the Sponsor and prior review and documented approval/favorable opinion 
from the IRB/IEC of an amendment, except where necessary to eliminate an immediate hazard(s) 
to clinical trial patients, or when the change(s) involves only logistical or administrative aspects of 
the trial. Any change agreed upon will be recorded in writing, the written amendment will be 
signed by the Investigator and by the Sponsor and the signed amendment will be filed with this 
clinical trial protocol. 
Any amendment to the clinical trial protocol requires written approval/favorable opinion by the 
IRB/IEC prior to its implementation, unless there are overriding safety reasons. 
In some instances, an amendment may require a change to the informed consent form. The 
Investigator must receive an IRB/IEC approval/favorable opinion concerning the revised 
informed consent form prior to implementation of the change and patient signature should be re-
collected if necessary.

Appendix A 
Contraceptive guidance and collection of pregnancy information 
DEFINITIONS 
Woman of childbearing potential (WOCBP) 
A woman is considered fertile following menarche and until becoming post-menopausal unless 
permanently sterile (see below). 
Women in the following categories are not considered WOCBP 
1. Premenarchal 
2. Premenopausal female with 1 of the following: 
- 
Documented hysterectomy 
- 
Documented bilateral salpingectomy 
- 
Documented bilateral oophorectomy. 
3. Postmenopausal female 
- 
A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal 
range may be used to confirm a postmenopausal state in women not using hormonal 
contraception or hormonal replacement therapy (HRT). However, in the absence of 12 
months of amenorrhea, a single FSH measurement is insufficient. 
- 
Females on hormone replacement therapy (HRT) and whose menopausal status is in 
doubt will be required to use one of the non-hormonal highly effective contraception 
methods if they wish to continue their HRT during the study. Otherwise, they must 
discontinue HRT to allow confirmation of postmenopausal status before study 
enrollment. 
CONTRACEPTION GUIDANCE 
Male participants 
No contraception requirements. 
Female participants 
Female patients of childbearing potential are eligible to participate if they are willing to practice 
true abstinence in line with their preferred and usual lifestyle, or if they agree to use a medically 
accepted form of contraception (either a barrier method, such as condom or diaphragm + 
spermicide, or a non-barrier method such as oral, injected, or implanted hormonal methods, or an 
intra-uterine device or system ) consistently and correctly while receiving eliglustat.

COLLECTION OF PREGNANCY INFORMATION 
Male participants with partners who become pregnant 
• The Investigator will attempt to collect pregnancy information on any male participant’s 
female partner who becomes pregnant while the male participant is in this study. This 
applies only to male participants who receive study treatment. 
• After obtaining the necessary signed informed consent from the pregnant female partner 
directly, the Investigator will record pregnancy information on the appropriate form and 
submit it to the Sponsor within 24 hours of learning of the partner’s pregnancy. The 
female partner will also be followed to determine the outcome of the pregnancy. 
Information on the status of the mother and child will be forwarded to the Sponsor. 
Generally, the follow-up will be no longer than 6 to 8 weeks following the estimated 
delivery date. Any termination of the pregnancy will be reported regardless of fetal status 
(presence or absence of anomalies) or indication for procedure. 
Female participants who become pregnant 
• The Investigator will collect pregnancy information on any female participant who 
becomes pregnant while participating in this study. Information will be recorded on the 
appropriate form and submitted to the Sponsor within 24 hours of learning of a 
participant's pregnancy. The participant will be followed to determine the outcome of the 
pregnancy. The Investigator will collect follow-up information on the participant and the 
neonate, and the information will be forwarded to the Sponsor. Generally, follow-up will 
not be required for longer than 6 to 8 weeks beyond the estimated delivery date. Any 
termination of pregnancy will be reported, regardless of fetal status (presence or absence 
of anomalies) or indication for procedure. 
• Any pregnancy complication or elective termination of a pregnancy will be reported as an 
AE or SAE. A spontaneous abortion is always considered to be an SAE and will be 
reported as such.  While the Investigator is not obligated to actively seek this information 
in former study participants, he or she may learn of an SAE through spontaneous 
reporting. 
• Any female participant who becomes pregnant while participating in the study must stop 
study treatment as soon as a pregnancy is confirmed and will be either withdrawn from the 
study or remain in the study. If a pregnant patient decides to remain in the study she must 
suspend the IMP till delivery and while breast feeding. The maximum duration of such an 
IMP suspension is 12 months. During the IMP suspension the patient must maintain 
compliance with all the other study requirements, except for the radiological examinations 
that are prohibited during pregnancy.
