The term “commercially accessible” is defined as 
when olipudase alfa is commercially accessible to 
each patient on an individual basis 
(eg, reimbursement being in place). The duration of 
study treatment with olipudase alfa between local 
Regulatory approval and commercial accessibility 
should not exceed 90 days. Therefore, as described 
below, after local Regulatory approval, the patient 
can continue in the LTS13632 study for a maximum 
of 127 days. 
x
This duration will ensure a maximum 90 days of 
study treatment with olipudase alfa for patients after 
local Regulatory approval and a safety follow up 
phone call 30 to 37 days after the last dose of study 
treatment.

STUDY No: GZ402665 (LTS13632) 
TITLE
A long-term study to assess the ongoing safety and efficacy of olipudase alfa in 
patients with acid sphingomyelinase deficiency 
INVESTIGATOR/TRIAL LOCATION
Multinational, multicenter 
PHASE OF DEVELOPMENT
2 
STUDY OBJECTIVE(S) 
 
Primary objective 
The primary objective of this study is to obtain data regarding the safety of 
olipudase alfa in patients with acid sphingomyelinase deficiency (ASMD) who 
are exposed to long-term treatment with olipudase alfa. 
Secondary objective(s)  
The secondary objectives of this study are to obtain data regarding the efficacy 
of olipudase alfa and to characterize olipudase alfa pharmacodynamics (PD) 
and pharmacokinetics (PK) following long-term administration. 
STUDY DESIGN 
This is a multinational, multicenter, nonrandomized, open-label, long-term 
treatment study of patients who have previously participated in a study of 
olipudase alfa. 
x
Patients will receive olipudase alfa every 2 weeks for 9 years or until 
olipudase alfa becomes commercially accessible (see maximum 
duration below), whichever comes first, unless the patient decides to 
enter another olipudase alfa clinical trial within the 9-year period prior 
to when olipudase alfa is commercially accessible.  
x
The term “commercially accessible” is defined as when olipudase alfa 
is commercially accessible to each patient on an individual basis 
(eg, reimbursement being in place). The duration of study treatment 
with olipudase alfa between local Regulatory approval and commercial 
accessibility should not exceed 90 days. Therefore, as described 
below, after local Regulatory approval, the patient can continue in the 
LTS13632 study for a maximum of 127 days.  
x
This will ensure 90 days of study treatment with olipudase alfa for 
patients after local Regulatory approval and a safety follow up phone 
call 30 to 37 days after the last dose of study treatment.  
x
Notwithstanding the above, every pediatric patient will be treated in 
the LTS13632 study for at least 3 years.  
x
The patient can switch immediately after the end of study treatment to 
commercial treatment without any gap in order to ensure continuity of 
treatment with olipudase alfa.  
Patients will start this study at the same dose they were receiving at the end of 
their primary study, provided that they have not missed more than 1 biweekly 
dose between studies. During the study, for pediatric patients who will reach 
adult age (18 years old) will receive the adult infusion volume.

Route(s) of administration 
IV infusion. 
Dose regimen 
Patients will receive an IV infusion of olipudase alfa every 2 weeks (± 3 days).  
Home infusion may be possible.  Patients must meet specific eligibility 
requirements.  In addition, the investigator and the sponsor must agree that 
home infusion is appropriate. Quarterly visits will occur at the site. If the site visit 
is not possible during a regional or national emergency declared by a 
governmental agency such as the COVID-19 pandemic due to site closure or 
extenuating circumstances that prevent an in-person site visit and home infusion 
is already approved for the eligible patient, quarterly visits will be done at 
home.Patients will continue their current dose if they have not missed more than 
1 dose between studies.  Dose reintroduction regimens may be required for 
patients who have missed more than 1 dose between studies or during this 
study, depending on their usual dose.  For patients receiving home infusions 
who have missed 2 or fewer doses, the investigator can decide whether 
reintroduction should occur at the hospital/study site or via home infusion. For 
patients who have missed 3 or more doses ≥0.6 mg/kg, reintroduction of 
olipudase alfa should occur at the hospital/study site.  If the site visit is not 
possible, During a regional or national emergency declared by a governmental 
agency, such as the COVID-19 pandemic, due to site closure or extenuating 
circumstances that prevent an in-person site visit, reintroduction may be done 
via home infusion in compliance with applicable country-specific regulations.

ASSESSMENT SCHEDULE 
Patients will be enrolled directly from their previous study.  (Note: The term 
“pediatric patients only” means patients coming from the original pediatric trial, 
DFI13803.  Some of these patients will reach adult age [18 years old] while in 
this study.  These patients will be adults by age, but they will remain part of the 
“pediatric patient” cohort.) 
In case of more than 3 infusions missed between trials, assessments 
(eg, efficacy biomarkers, sphingomyelin and metabolites) may be repeated at 
study entry. 
Patients who require dose reintroduction will have these assessments at each 
infusion until reaching their usual dose of olipudase alfa: 
x
Before infusion: vital sign measurements, liver function tests (LFTs), 
hematology, and safety biomarkers. 
x
Immediately after infusion: vital sign measurements. 
x
24 hours after infusion: vital sign measurements, LFTs, and safety 
biomarkers. 
x
48 hours  after infusion: vital sign measurements, LFTs and safety 
biomarkers. The 48 hours post-infusion assessments will no longer be 
assessed after the cutoff date for a planned second database lock of 
the study for regulatory submissions in 2021. 
During the dose escalation period, for transaminases assessed after 
infusion, if any AST or ALT value is >2x baseline and >ULN, the test should 
be repeated prior to the next scheduled infusion. Depending on the test 
results, the dose can be adjusted (repeated or reduced) or treatment can

For initial dose escalation: last values prior to first dose of olipudase 
alfa 
x
For dose re-escalation: last values prior to the first re-escalation dose 
Safety will be monitored continuously.  Safety and efficacy assessments will 
occur regularly every 3, 6, 9, and 12 months.  In the first 5 years, 
pharmacodynamic (PD) evaluations will occur every 3 months then every 6 
months after the cutoff date for a planned second database lock of the study for 
purpose of regulatory submissions in 2021. After 5 years, PD evaluations will 
occur every 12 months. PK evaluation will occur every 12 months only in the 
first 5 years and upon introduction of Process C(
) or Process C(
) at any 
time during the study. 
For patients completing or discontinuing/withdrawing from the study, there will 
be a post treatment period consisting of an end-of-treatment (EOT) visit 2 weeks 
(±7 days) after the last administered dose of olipudase alfa and a safety 
follow-up phone call 30 to 37 days after the last administered dose. 
STATISTICAL CONSIDERATIONS
Sample size determination
Sample size is determined by the number of patients who complete the 
treatment phase of a previous clinical study of olipudase alfa, sign the informed 
consent form of the LTS13632 study, and meet the eligibility criteria. It is 
expected that the sample size for this study will be approximately 25. 
Analysis populations
The safety set will include all enrolled patients who received at least 1 dose 
(partial or total) of olipudase alfa in the current study. 
Analysis of safety
Safety analyses will include a summary of treatment duration, the total number 
of infusions received, and the total amount of olipudase alfa received.  
Frequencies (number and percentage) of patients with 1 or more 
treatment-emergent AEs will be summarized by the Medical Dictionary for 
Regulatory Activities System Organ Class (SOC) and preferred term (PT). All 
treatment-emergent AEs, all treatment-emergent AEs potentially related to 
olipudase alfa, all treatment-emergent AEs leading to treatment discontinuation 
and study discontinuation, all treatment-emergent AEs that are infusion-
associated reactions, all treatment--emergent serious adverse events (SAEs) 
(including treatment-related SAEs), and all AEs with fatal outcomes (including 
fatal treatment-emergent AEs) will be summarized.  Other safety variables, 
including laboratory parameters and vital sign measurements, will be 
summarized by study visit and by dose. 
The PK analysis will include all patients who receive at least 1 infusion of study 
drug after PK analysis informed consent and have evaluable PK data.   
Other analysis populations, such as for pharmacogenomics, if any, will be 
defined in the SAP.

Analysis of secondary endpoints
Summary statistics for the values, nominal change from baseline, and percent 
change from baseline will be presented for efficacy assessments at various 
study time points.  The association between changes in efficacy parameters and 
total amount of drug received will be examined. 
Plasma concentration-time data will be analyzed using actual dosing and 
sampling times by noncompartmental methods. Pharmacokinetic parameters 
will be calculated for each patient and summarized by dose level and study 
week. As data permit, PK parameters may also be evaluated across dose level 
at each manufacturing scale.  Metabolite levels will be summarized by dose 
level and time point using descriptive statistics.
DURATION OF STUDY PERIOD 
(per patient) 
x
The maximum study duration per patient is 9 years or until olipudase 
alfa becomes commercially accessible (see maximum duration 
below), whichever comes first, unless the patient decides to enter 
another olipudase alfa clinical trial within the 9-year period prior to 
when olipudase alfa is commercially accessible. 
x
The term “commercially accessible” is defined as when olipudase alfa 
is commercially accessible to each patient on an individual basis 
(eg, reimbursement being in place). The duration of study treatment 
with olipudase alfa between  local Regulatory approval and 
commercial accessibility should not exceed 90 days. Therefore, as 
described below, after local Regulatory approval, the patient can 
continue in the LTS13632 study for a maximum of 127 days. 
x
This will ensure 90 days of study treatment with olipudase alfa for 
patients after local Regulatory approval and a safety follow up phone 
call 30 to 37 days after the last dose of study treatment. 
x
Notwithstanding the above, every pediatric patient will be treated in 
the LTS13632 study for at least 3 years.  
x
The patient can switch immediately after the end of study treatment to 
commercial treatment without any gap in order to ensure continuity of 
treatment with olipudase alfa. An EOT visit after the last administered 
dose of study treatment and a safety follow-up phone call 30 to 37 
days after the last administered dose of study treatment will also apply 
in case the patient switches immediately after the end of study 
treatment to commercial treatment.

STUDY FLOW CHARTS
Table 1 and Table 3 are the study flow charts for adult patients coming from study DFI13412, 
corresponding to the period Year 1 to Year 5 and beyond Year 5, respectively. Complementary 
flow charts have been added for the changes to be effective after the cutoff date for a planned 
second database lock of the study for purpose of regulatory submissions in 2021 (Table 2 and 
Table 4). Table 5, Table 7, and Table 9 are the study flow charts for pediatric patients  coming 
from the pediatric study DFI13803 and correspond to Year 1, Year 2 through Year 5, and beyond 
Year 5,  respectively. Complementary flow charts have been added for the changes to be effective 
after the cutoff date for a planned second database lock of the study for purpose of regulatory 
submissions in 2021 (Table 6, and Table 10). Table 11 and Table 12 are the pharmacokinetic (PK)
sampling schedules for adults and pediatric patients, respectively.
Patients will be enrolled directly from their previous study after providing informed consent.
In case of more than 3 infusions missed between trials, assessments (eg, efficacy biomarkers, 
sphingomyelin and metabolites) may be repeated at study entry.  The investigator, after discussion 
with the sponsor, may order individualized assessments before the patient receives the first infusion
in this study.
Dose reintroduction regimens may be required for patients who have missed more than 1 dose 
between studies or during this study (LTS13632), depending on their usual dose. For patients 
receiving home infusions who have missed 2 or fewer doses, the investigator can decide whether 
reintroduction should occur at the hospital/study site or via home infusion. For patients who miss 
3 or more doses ≥0.6 mg/kg, reintroduction of olipudase alfa should occur at the study site. If the 
site visit is not possible during a regional or national emergency declared by a governmental 
agency such as the COVID-19 pandemic due to site closure or extenuating circumstances that 
prevent an in-person site visit, reintroduction can occur via home infusion in compliance with 
applicable country-specific regulations.
Patients who require dose reintroduction will have these assessments at each infusion until 
reaching their usual dose of olipudase alfa:
x
Before infusion: vital sign measurements, liver function tests (LFTs), hematology, and 
safety biomarkers.
x
Immediately after infusion: vital sign measurements.
x
24 hours after infusion: vital sign measurements, LFTs, hematology, and safety 
biomarkers.
x
48 hours after infusion: vital sign measurements, LFTs, hematology, and safety 
biomarkers. 
The 48 hours post-infusion assessments will no longer be assessed after the cutoff date for 
a planned second database lock of the study for purpose of regulatory submissions in 
2021.

During the dose escalation period, for transaminases assessed after infusion, if any AST or 
ALT value is >2x baseline and >ULN, the test should be repeated prior to the next 
scheduled infusion. Depending on the test results, the dose can be adjusted (repeated or 
reduced) or treatment can be withheld to allow additional transaminase monitoring, based 
on the physician’s clinical judgment.
Baseline is defined as the following: 
x
For initial dose escalation: last values prior to first dose of olipudase alfa
x
For dose re-escalation: last values prior to the first re-escalation dose
For a new manufacturing scale, if treatment is not interrupted, PK sample collection will take 
place at the patient’s last infusion under the current manufacturing scale and at the first infusion 
under the new manufacturing scale. For introduction of drug product from Process C(
), if
treatment is not interrupted, PK sample collection will take place at the second infusion under 
Process C(
). If introduction of Process C(
) occurs, sample collection of anti olipudase alfa 
antibody (IgG) will be monthly for the first 6 months after introducing the drug product from 
Process C(
) then quarterly after that.
If a PK or IgG sample collection for the planned introduction of drug product from Process C(
) 
was erroneously taken, the future sample collection will be adjusted to the blood volume per each 
age cohort in order to avoid excessive blood withdrawal. For specific details, please refer to Study 
Manual. See Section 9.3.8 for time points and additional information.

Patients will receive olipudase alfa every 2 weeks (±3 days). Quarterly visits will occur at the site. If the site visit is not possible during a regional or national emergency declared by a 
governmental agency such as the COVID-19 pandemic due to site closure or extenuating circumstances that prevent an in-person site visit and home infusion is already approved for the 
eligible patient, quarterly visits will be done at home. Quarterly visit specific assessments that need a site visit will not be done at that time and will be done as unscheduled as soon as site 
visits become available. In such a case, some of the quarterly visit assessments may be done by home nurse (eg, lab sampling) and by the site through the phone (eg, Health-related quality of 
life instruments). Telehealth visits are an acceptable alternative to site visits If the site visit is not possible during a regional or national emergency declared by a governmental agency such as 
the COVID-19 pandemic due to site closure or extenuating circumstances that prevent an in-person site visit, in accordance with institutional policy and with applicable country-specific 
regulations.

Patients will receive olipudase alfa every 2 weeks (±3 days). Quarterly visits will occur at the site. If the site visit is not possible during a regional or national emergency declared by a 
governmental agency such as the COVID-19 pandemic due to site closure or extenuating circumstances that prevent an in-person site visit and home infusion is already approved for the 
eligible patient, quarterly visits will be done at home. Quarterly visit specific assessments that need a site visit will not be done at that time and will be done as unscheduled as soon as site visits 
become available. In such a case, some of the quarterly visit assessments may be done by home nurse (eg, lab sampling) and by the site through the phone (eg, Health-related quality of life 
instruments). Telehealth visits are an acceptable alternative to site visits if the site visit is not possible during a regional or national emergency declared by a governmental agency such as the 
COVID-19 pandemic due to site closure or extenuating circumstances that prevent an in-person site visit, in accordance with institutional policy and with applicable country-specific regulations.

All patients will have a visit 2 weeks (±7 days) after the last dose of study treatment. For the end of study/early discontinuation visit, NPB HAQ, abdominal MRI, HRCT, chest X-ray, pulmonary 
function tests, cycle ergometry, and Doppler echocardiography will not be repeated if they had been done within 3 months prior.  DXA and bone MRI will not be repeated if they were done 
within 6 months prior.

FLOW CHART FOR PEDIATRIC (FORMER DFI13803) PATIENTS: YEAR 1
The term “pediatric patients” means patients coming from the original pediatric trial, DFI13803. Some of these patients will reach adult age 
(18 years old) while in this study.  These patients will be adults by age, but they will remain part of the “pediatric patient” cohort.

Patients from DFI13803 are to follow the pediatric schedule of events in the LTS13632 study.  The pediatric schedule of events is based on pediatric patients receiving 64 weeks of treatment 
in the prior DFI13803 study. The adult schedule of events is based on adult patients receiving 26 weeks of treatment in the prior DFI13412 study. Patients will receive olipudase alfa every 
2 weeks (±3 days). Quarterly visits will occur at the site. If the site visit is not possible during a regional or national emergency declared by a governmental agency such as the COVID-19 
pandemic due to site closure or extenuating circumstances that prevent an in-person site visit and home infusion is already approved for the eligible patient, quarterly visits will be done at 
home. Quarterly visit specific assessments that need a site visit will not be done at that time and will be done as unscheduled as soon as site visits become available. In such a case, some of 
the quarterly visit assessments may be done by home nurse (eg, lab sampling) and by the site through the phone (eg, Health-related quality of life instruments). Telehealth visits are an

acceptable alternative to site visits if the site visit is not possible during a regional or national emergency declared by a governmental agency such as the COVID-19 pandemic due to site 
closure or extenuating circumstances that prevent an in-person site visit, in accordance with institutional policy and with applicable country-specific regulations. 
b
All patients will have a visit 2 weeks (±7 days) after the last dose of study treatment.  For the end of study/early discontinuation visit, abdominal MRI, HRCT, chest X-ray, pulmonary function 
tests (PFTs) , Doppler echocardiography, hand X-ray, and pediatric health outcome questionnaires will not be repeated if they had been done within the prior 3 months. 
c
All patients will have a final safety follow-up phone call 30 to 37 days after the last dose of study treatment. 
d
If possible, the neurological examination should be performed by the same neurologist who performed it in the DFI13803 study. If possible, the same neurologist should perform the 
neurological examination throughout the study. 
e
Weight at previous on-site visit may be used to calculate drug dosage at current visit.  Weight is not required at home infusion visits.  Body mass index (BMI) will be calculated. 
f
At time points when multiple assessments are scheduled, the order will be: vital sign measurements, electrocardiogram, pharmacokinetics (PK). 
g
As indicated, an additional sample will be collected for hemoglobin and platelet count at least 24 hours and up to 2 weeks apart from the sample collected for clinical laboratory tests. If drug 
product from a manufacturing scale change or an updated manufacturing process is administered, 2 samples will be taken during an infusion 3 months after introducing the new scale or the 
updated manufactured process one for deferential hematology and the other for hemoglobin and platelet count at least 24 hours and up to 2 weeks apart.

j
Assessments should be performed at the same time (±2 hours) to ensure consistency.

Pharmacokinetic testing will only occur yearly and upon introduction of a manufacturing scale change from Process B to Process C(
) or from Process C(
) to the updated manufacturing 
process C(
).  For Process C(
), if treatment is not interrupted, PK sample collection will take place at the patient’s last infusion under Process B and at the first infusion under Process

tests (PFTs) , Doppler echocardiography, hand X-ray, and pediatric health outcome questionnaires will not be repeated if they had been done within the prior 3 months. 
c
All patients will have a final safety follow-up phone call 30 to 37 days after the last dose of study treatment 
d
If possible, the neurological examination should be performed by the same neurologist who performed it in the DFI13803 study. If possible, the same neurologist should perform the 
neurological examination throughout the study.

Weight at previous on-site visit may be used to calculate drug dosage at current visit.  Weight is not required at home infusion visits.  Body mass index (BMI) will be calculated. 
f
At time points when multiple assessments are scheduled, the order will be: vital sign measurements, electrocardiogram, pharmacokinetics (PK). 
g
As indicated, an additional sample will be collected for hemoglobin and platelet count at least 24 hours and up to 2 weeks apart from the sample collected for clinical laboratory tests. If drug 
product from a manufacturing scale change or an updated manufacturing process is administered, 2 samples will be taken during an infusion 3 months after introducing the new scale or the 
updated manufactured process one for deferential hematology and the other for hemoglobin and platelet count at least 24 hours and up to 2 weeks apart. 
h
Patients must rest in the supine position for 5-10 minutes prior to and during all electrocardiograms. 
i
Only at selected sites 
j
Assessments should be performed at the same time (±2 hours) to ensure consistency. 
k
Pharmacokinetic testing will only occur yearly and upon introduction of a manufacturing scale change from Process B to Process C(
) or from Process C(
) to the updated manufacturing 
process C(
).  For Process C(
), if treatment is not interrupted, PK sample collection will take place at the patient’s last infusion under Process B and at the first infusion under Process 
C(
). For the switch from Process C(
) to Process C(
), if treatment is not interrupted, PK sample collection will take place at the second infusion under Process C(
).  In case 
reintroduction of olipudase alfa coincides with introduction of a drug product from Process C(
) or Process C(
), PK samples will be collected at the infusion at which patients receive their 
usual dose of olipudase alfa under the new process.  For schedule of PK assessment in children, see Section 1.6, Table 12.

FLOW CHART FOR PEDIATRIC (FORMER DFI13803) PATIENTS: YEAR 2 THROUGH YEAR 5
The term “pediatric patients” means patients coming from the original pediatric trial, DFI13803.  Some of these patients will reach adult age 
(18 years old) while in this study. These patients will be adults by age, but they will remain part of the “pediatric patient” cohort.

Patients from DFI13803 are to follow the pediatric schedule of events in the LTS13632 study.  The pediatric schedule of events is based on pediatric patients receiving 64 weeks of treatment 
in the prior DFI13803 study.  The adult schedule of events is based on adult patients receiving 26 weeks of treatment in the prior DFI13412 study. All patients will have a visit 2 weeks 
(±3 days) after the last Quarterly visits will occur at the site. If the site visit is not possible during a regional or national emergency declared by a governmental agency such as the COVID-19 
pandemic due to site closure or extenuating circumstances that prevent an in-person site visit and home infusion is already approved for the eligible patient, quarterly visits will be done at 
home. Quarterly visit specific assessments that need a site visit will not be done at that time and will be done as unscheduled as soon as site visits become available. In such a case, some of 
the quarterly visit assessments may be done by home nurse (eg, lab sampling) and by the site through the phone (eg, Health-related quality of life instruments). Telehealth visits are an 
acceptable alternative to site visits, If the site visit is not possible during a regional or national emergency declared by a governmental agency such as the COVID-19 pandemic due to site 
closure or extenuating circumstances that prevent an in-person site visit, in accordance with institutional policy and with applicable country-specific regulations. 
b
All patients will have a visit 2 weeks (±7 days) after the last dose of study treatment.  For the end of study/early discontinuation visit, abdominal MRI, HRCT, chest X-ray, pulmonary function 
tests (PFTs), Doppler echocardiography, hand X-ray, and pediatric health outcome questionnaires will not be repeated if they had been done within 3 months prior. 
c
All patients will have a final safety follow-up phone call 30 to 37 days after the last dose of study treatment. 
d
If possible, the neurological examination should be performed by the same neurologist who performed it in the DFI13803 study.  If possible, the same neurologist should perform the 
neurological examination throughout the study. 
e
Weight at previous on-site visit may be used to calculate drug dosage at current visit.  Weight is not required at home infusion visits unless quarterly visit occurs at home.  Body mass index 
(BMI) will be calculated. 
f
At time points when multiple assessments are scheduled, the order will be: vital sign measurements, electrocardiogram, pharmacokinetics (PK). 
g
As indicated, an additional sample will be collected for hemoglobin and platelet count at least 24 hours and up to 2 weeks apart from the sample collected for clinical laboratory tests. If drug 
product from a manufacturing scale change or an updated manufacturing process is administered, 2 samples will be taken during an infusion 3 months after introducing the new scale or the 
updated manufactured process one for deferential hematology and the other for hemoglobin and platelet count at least 24 hours and up to 2 weeks apart. 
h
Patients must rest in the supine position for 5-10 minutes prior to and during all electrocardiograms. 
i
Upon a manufacturing scale change that occurs beyond Year 2, an abdominal MRI and pulmonary function tests will be performed at the first 6-month visit after the change, but only if that 
6-month visit is not a 12-month visit at which the assessment is already scheduled.  Pulmonary function tests will be performed for patients who had a baseline assessment in the DFI13803

Patients from DFI13803 are to follow the pediatric schedule of events in the LTS13632 study.  The pediatric schedule of events is based on pediatric patients receiving 64 weeks of treatment 
in the prior DFI13803 study.  The adult schedule of events is based on adult patients receiving 26 weeks of treatment in the prior DFI13412 study. All patients will have a visit 2 weeks 
(±3 days) after the last Quarterly visits will occur at the site. If the site visit is not possible during a regional or national emergency declared by a governmental agency such as the COVID-19 
pandemic due to site closure or extenuating circumstances that prevent an in-person site visit and home infusion is already approved for the eligible patient, quarterly visits will be done at 
home. Quarterly visit specific assessments that need a site visit will not be done at that time and will be done as unscheduled as soon as site visits become available. In such a case, some of

the quarterly visit assessments may be done by home nurse (eg, lab sampling) and by the site through the phone (eg, Health-related quality of life instruments). Telehealth visits are an 
acceptable alternative to site visits, If the site visit is not possible during a regional or national emergency declared by a governmental agency such as the COVID-19 pandemic due to site 
closure or extenuating circumstances that prevent an in-person site visit, in accordance with institutional policy and with applicable country-specific regulations. 
b
All patients will have a visit 2 weeks (±7 days) after the last dose of study treatment.  For the end of study/early discontinuation visit, abdominal MRI, HRCT, chest X-ray, pulmonary function 
tests (PFTs), Doppler echocardiography, hand X-ray, and pediatric health outcome questionnaires will not be repeated if they had been done within 3 months prior. 
c
All patients will have a final safety follow-up phone call 30 to 37 days after the last dose of study treatment. 
d
If possible, the neurological examination should be performed by the same neurologist who performed it in the DFI13803 study.  If possible, the same neurologist should perform the 
neurological examination throughout the study. 
e
Weight at previous on-site visit may be used to calculate drug dosage at current visit.  Weight is not required at home infusion visits unless quarterly visit occurs at home.  Body mass index 
(BMI) will be calculated. 
f
At time points when multiple assessments are scheduled, the order will be: vital sign measurements, electrocardiogram, pharmacokinetics (PK). 
g
As indicated, an additional sample will be collected for hemoglobin and platelet count at least 24 hours and up to 2 weeks apart from the sample collected for clinical laboratory tests During 
the study period, for the switch from Process B to Process C(
) or from Process C(
) to the updated manufacturing process C(
) , 2 samples will be taken during an infusion 3 months after 
introducing Process C(
) or Process C(
), one for deferential hematology and the other for hemoglobin and platelet count at least 24 hours and up to 2 weeks apart. 
h
Patients must rest in the supine position for 5-10 minutes prior to and during all electrocardiograms. 
i
During the study period, for the switch from Process B to Process C or from Process C(
) to the updated manufacturing process C(
), that occurs beyond Year 2, an abdominal MRI and 
pulmonary function tests will be performed at the first 6-month visit after the change, but only if that 6-month visit is not a 12-month visit at which the assessment is already scheduled.  
Pulmonary function tests will be performed for patients who had a baseline assessment in the DFI13803 study. 
j
Only at selected sites. 
k
Assessments should be performed at the same time (±2 hours) to ensure consistency. 
l
Pharmacokinetic testing will only occur yearly and upon introduction of a manufacturing scale change from Process B to Process C(
) or from Process C(
) to the updated manufacturing 
process C(
),.  For Process C(
), if treatment is not interrupted, PK sample collection will take place at the patient’s last infusion under process B and at the first infusion under Process 
C(
). For the switch from Process C(
) to Process C(
), if treatment is not interrupted, PK sample collection will take place at the second infusion under Process C(
).  In case 
reintroduction of olipudase alfa coincides with introduction of a drug product from Process C(
) or Process C(
), PK samples will be collected at the infusion at which patients receive their 
usual dose of olipudase alfa under the new process.  For schedule of PK assessment in children, see Section 1.6, Table 12.

Patients from DFI13803 are to follow the pediatric schedule of events in the LTS13632 study.  The pediatric schedule of events is based on pediatric patients receiving 64 weeks of treatment in 
the prior DFI13803 study.  The adult schedule of events is based on adult patients receiving 26 weeks of treatment in the prior DFI13412 study. All patients will have a visit 2 weeks (±3 days).  
Quarterly visits will occur at the site. If the site visit is not possible during a regional or national emergency declared by a governmental agency such as the COVID-19 pandemic due to site 
closure or extenuating circumstances that prevent an in-person site visit and home infusion is already approved for the eligible patient, quarterly visits will be done at home. Quarterly visit 
specific assessments that need a site visit will not be done at that time and will be done as unscheduled as soon as site visits become available. In such a case, some of the quarterly visit

assessments may be done by home nurse (eg, lab sampling) and by the site through the phone (eg, Health-related quality of life instruments). Telehealth visits are an acceptable alternative to 
site visits, if the site visit is not possible during a regional or national emergency declared by a governmental agency such as the COVID-19 pandemic due to site closure or extenuating 
circumstances that prevent an in-person site visit, in accordance with institutional policy and with applicable country-specific regulations. 
b
All patients will have a visit 2 weeks (±7 days) after the last dose of study treatment.  For the end of study/early discontinuation visit, all “beyond Year 5” assessments will not be repeated if they 
had been done within 6 months prior. 
c
All patients will have a final safety follow-up phone call 30 to 37 days after the last dose of study treatment. 
d
If possible, the neurological examination should be performed by the same neurologist who performed it in the DFI13803 study.  If possible, the same neurologist should perform the 
neurological examination throughout the study. 
e
Weight at previous on-site visit may be used to calculate drug dosage at current visit.  Weight is not required at home infusion visits unless quarterly visit occurs at home.  Body mass index 
(BMI) will be calculated. 
f
At time points when multiple assessments are scheduled, the order will be: vital sign measurements then electrocardiogram. 
g
Patients must rest in the supine position for 5-10 minutes prior to and during all electrocardiograms. 
h
Assessments should be performed at the same time (±2 hours) to ensure consistency. 
i
Beyond 5 years, pharmacokinetic testing will only occur upon the introduction of a drug product from Process C(
) or Process C(
).  For Process C(
), if treatment is not interrupted, PK 
sample collection will take place at the patient’s last infusion under Process B and at the first infusion under Process C(
).  During the study period, for the switch from Process C(
) to 
Process C(
), if treatment is not interrupted, PK sample collection will take place at the second infusion under Process C(
).  In case reintroduction of olipudase alfa coincides with 
introduction of drug product from Process C(
) or Process C(
), PK samples will be collected at the infusion at which patients receive their usual dose of olipudase alfa under the new 
process.  For schedule of PK assessment in adults, see Section 1.6, Table 11. 
ApoA1=apolipoprotein A1; ApoB=apolipoprotein B; β-HCG=beta human chorionic gonadotropin; DLCO=diffusing capacity of the lung for carbon monoxide; FEV1=forced expiratory volume in 
1 second; FVC=forced vital capacity; HDL=high-density lipoprotein; hsCRP=high-sensitivity C-reactive protein; IAR= infusion-associated reaction; Ig=immunoglobulin; IL=interleukin; 
LDL=low-density lipoprotein; LFT=liver function test; MRI=magnetic resonance imaging; PedsQL=Pediatric Quality of Life; TLC=total lung capacity; VLDL=very low-density lipoprotein.

STUDY FLOW CHART: PHARMACOKINETIC SAMPLING
For both adult and pediatric patients, PK testing will only occur yearly (up to 5 years) and upon 
the introduction of a drug product from Process C(
) or Process C(
) at any time during the 
study.  For Process C(
), if treatment is not interrupted, PK collection will take place at the 
patient’s last infusion under the current manufacturing scale and at the first infusion Process 
C(
). For introduction of drug product from Process C(
), if treatment is not interrupted, PK 
sample collection will take place at the second infusion under the Process C(
).  In case 
reintroduction of olipudase alfa coincides with introduction of drug product from Process C(
) or 
Process C(
), PK samples will be collected at the infusion at which patients receive their usual 
dose of olipudase alfa under the new process. For introduction of drug product from Process 
C(
), if treatment is not interrupted, PK sample collection will take place at the second infusion 
under Process C(
). 
If a PK sample collection for the planned introduction of drug product from an updated 
manufacturing process was erroneously taken, the future sample collection will be adjusted 
according to the blood volume allowed per each age cohort in order to avoid excessive blood 
withdrawal. For specific details, please refer to Study Manual.

INTRODUCTION AND RATIONALE
4.1
INTRODUCTION
Human acid sphingomyelinase deficiency (ASMD) is a serious, rare, life threatening lysosomal 
storage disorder for which only palliative treatment exists. Patients with ASMD are unable to 
metabolize sphingomyelin properly due to mutations in SMPD1, the gene encoding acid 
sphingomyelinase (ASM), whose transcription and translation results in a defective (ASM) 
enzyme. Inactivity of ASM leads to the lysosomal accumulation of sphingomyelin and, 
secondarily, increases in cholesterol and other related lipids, mostly in the organs, such as the 
spleen, liver, lung, and bone marrow.
Historically, ASMD has been diagnosed as Niemann-Pick Disease (NPD) and of either Type A or
Type B disease. Type A (NPD A) is characterized as the early-onset and acute neuropathic form 
of (NPD) and results in failure to thrive, hepatosplenomegaly, rapidly progressive neurological 
degeneration, and death, usually before the age of 3 years (1). Niemann-Pick disease Type B
(NPD B) is a milder disease with little or no neurological involvement that may already have 
manifestations in childhood.  The most common disease manifestation is hepatosplenomegaly. 
Other more variable features include liver dysfunction, pulmonary disease, retinal stigmata, and 
growth retardation.  Niemann-Pick disease Type B is usually diagnosed in childhood after 
organomegaly is observed, typically after the age of 2 years. Most patients diagnosed with Type B
disease live into adulthood.  Being an autosomal recessive single gene disease, ASMD is 
acknowledged to generate a spectrum of phenotypes. Accordingly, cases classified as intermediate 
to the A and B extremes have been reported. Patients with this intermediate form (NPD A/B) may 
develop neurologic symptoms during childhood and have a chronic neurodegenerative disease 
course.
Sanofi Genzyme is developing a potential enzyme replacement therapy for ASMD with olipudase 
alfa, a recombinant human acid sphingomyelinase, for the treatment of the non-neurological 
manifestations of ASMD.  This recombinantly-derived enzyme is expressed in Chinese hamster 
ovarian cells transfected with olipudase alfa complementary DNA that encodes a 627-residue 
peptide chain.  The resulting gene product retains the enzymatic activity and lysosomal targeting 
of the native protein.
Proof of concept for olipudase alfa therapy has been demonstrated in the acid sphingomyelinase 
knock-out (ASMKO) mouse (2), which exhibits both systemic and neurological features of 
ASMD.  Repeat intravenous (IV) bolus administration of olipudase alfa to ASMKO mice led to 
dose-dependent reductions of sphingomyelin in visceral organs and in the lungs to a lesser extent, 
but was unable to prevent neurologic decline and prolong survival (3, 4). However, chronic 
dosing in the ASMKO animal model is limited because the mice succumb to the neurologic 
disease resulting from the natural progression of complete ASMD in approximately 6 to 8 months.
Pharmacodynamic (PD), pharmacokinetic (PK), and toxicological studies conducted in the 
ASMKO mouse found significant reductions of sphingomyelin in the liver, lung, kidney, and 
spleen at olipudase alfa doses ranging from 0.1 to 5.0 mg/kg in a time-dependent manner;

however, toxicity was observed in ASMKO mice given single high-dose boluses of olipudase alfa 
(≥10 mg/kg).  The same single, high doses did not cause toxic effects in normal mice, Sprague 
Dawley rats, or cynomolgus monkeys, suggesting that catabolites of sphingomyelin, and not 
olipudase alfa itself, were the cause of the toxic effects.  Subsequent “debulking” studies in 
ASMKO mice demonstrated that a slow reduction in the sphingomyelin load over time using 
multiple low doses of olipudase alfa (4 doses of 3.0 mg/kg of olipudase alfa administered over 
8 days) followed by a high dose (20 mg/kg 3 days later) prevented the toxicity associated with the 
single initial high doses.  These findings suggest that the observed toxicity is related to the rate of 
substrate degradation and that step-wise removal of substrate likely mitigates toxicity. 
Furthermore, repeat high doses of olipudase alfa (30 mg/kg every 2 weeks for 7 doses) 
administered after a 7-day debulking period (3 mg/kg on Days 1, 3, 5, and 7) also did not cause 
toxicity.
During clinical development of olipudase alfa, incremental changes were made to the olipudase 
alfa manufacturing process. The different processes are referred to as Process B, C(
) and C(
). 
In a completed Phase 1 study (5), the safety, PK, and PD profiles of single, ascending doses of 
olipudase alfa were evaluated. Single doses of 0.03, 0.1, 0.3, 0.6, and 1.0 mg/kg of olipudase alfa 
were infused sequentially by dose cohort in 11 adult patients with ASMD. Study results found 
dose-related increases in ceramide, bilirubin, high-sensitivity C-reactive protein (hsCRP), and 
other acute phase reactants in patients that peaked 24 to 48 hours postdose and resolved by 
Day 14.  Reported adverse events (AEs) involving constitutional symptoms (pain, fever, nausea, 
and vomiting) were consistent with first-dose-related toxicity and occurred in a dose-dependent 
fashion as was previously observed in the ASMKO mouse.  Serious adverse events (SAEs) related 
to olipudase alfa treatment were not reported. The sponsor terminated the study subsequent to 
a single patient dosed at 1.0 mg/kg of olipudase alfa presenting with hyperbilirubinemia and 
an acute-phase reaction (APR) with clinical symptoms. Of note, this patient was subsequently 
confirmed to have Gilbert’s syndrome. Because there were no other signs of liver toxicity or 
hemolysis, the observed hyperbilirubinemia may have been secondary to specific inhibition of 
bilirubin uptake into hepatocytes and/or glucuronide conjugation of bilirubin within hepatocytes.
In a completed Phase 1b, open-label, multicenter ascending-dose study in 5 adult patients with 
ASMD, the safety and tolerability of olipudase alfa were evaluated during a 26-week treatment 
period (6). Patients received an initial IV dose of 0.1 mg/kg of olipudase alfa, then the dose was 
escalated in a stepwise manner to a final target IV dose of 3.0 mg/kg.  All patients remained at 
3.0 mg/kg for the remainder of the treatment period. Upon completion of the study, all patients 
enrolled into an open-label, long-term treatment study. Results from this trial demonstrated that 
the progressive, within-patient olipudase alfa dose escalation regimen was well tolerated in adult 
ASMD patients. No serious or severe AEs or deaths were reported in the study.  Related AEs 
consisted predominantly of infusion-associated reactions (IARs), most of which were mild in 
severity with all patients recovering without sequelae. At the end of the 6-month treatment period, 
a positive response to treatment with olipudase alfa was observed in several individual efficacy 
parameters. This included mean decreases in spleen and liver volumes by 25.3% and 17.1%, 
respectively; decreased interstitial lung disease (ILD) scores; increased percent predicted diffusing 
capacity of the lung for carbon monoxide (DLCO); reduction in serum chitotriosidase, chemokine 
(CC-motif) ligand 18 (CCL-18), and angiotensin-converting enzyme (ACE); a positive trend

towards a less proatherogenic lipid profile; and, trends for improvement in quality of life 
assessments for fatigue and pain.
Other clinical studies of olipudase alfa are planned or ongoing.  These include:
x
A Phase 1/2, multicenter, open-label, ascending-dose study to evaluate the safety, 
tolerability, PK, PD, and exploratory efficacy of olipudase alfa in pediatric patients aged 
<18 years with ASMD.
x
A Phase 2/3, multicenter, randomized, double-blinded, placebo-controlled repeat-dose 
study to evaluate the efficacy, safety, PD, and PK of olipudase alfa in patients 
with ASMD.
A complete summary of nonclinical and clinical experience with olipudase alfa can be found in 
the investigator’s brochure.
4.2
STUDY RATIONALE
Cumulative data from preclinical and human studies conducted to date with olipudase alfa 
demonstrate both the safety and tolerability of repeat dosing of olipudase alfa.  This study will 
provide long-term data on olipudase alfa in pediatric and adult patients with ASMD.
This study is being conducted to allow patients with ASMD to continue the olipudase alfa 
treatment they were receiving at the end of their primary study after that study is completed. 
Individual dose adjustments are allowed in this study, but may also be recommended based on 
results from completed or ongoing studies of olipudase alfa. The primary objective of this study is 
to obtain safety data in pediatric and adult patients with ASMD who are exposed to long-term 
treatment with olipudase alfa. Secondary objectives are to obtain efficacy, PK, and PD data.
Treatment Period
x
The current study is an open-label, long-term treatment study planned for 9 years, or until
olipudase alfa becomes commercially accessible (see maximum duration below), whichever 
comes first, unless the patient decides to enter another olipudase alfa clinical trial within the 
9-year period prior to when olipudase alfa is commercially accessible.
x
The term “commercially accessible” is defined as when olipudase alfa is commercially 
accessible to each patient on an individual basis (eg, reimbursement being in place). The 
duration of study treatment with olipudase alfa between local Regulatory approval and 
commercial accessibility should not exceed 90 days. Therefore, as described below, after 
local Regulatory approval, the patient can continue in the LTS13632 study for a maximum of 
127 days.
x
This will ensure 90 days of study treatment with olipudase alfa for patients after local 
Regulatory approval and a safety follow up phone call 30 to 37 days after the last dose of 
study treatment. 
x
Notwithstanding the above, every pediatric patient will be treated in the LTS13632 study for 
at least 3 years to comply with the agreed PIP. 
x
The patient can switch immediately after the end of study treatment to commercial treatment 
without any gap in order to ensure continuity of treatment with olipudase alfa.

STUDY DESIGN
This is a multinational, multicenter, nonrandomized, open-label, long-term treatment study of 
approximately 25 patients who have previously participated in a study of olipudase alfa. 5 adult 
patients rolled over from study DFI13412 into LTS13632 study and approximately 20 pediatric 
patients are expected to roll over from study DFI13803. Patients will be enrolled directly into this 
study from their previous study.
Treatment Period
x
Enrolled patients will receive an IV infusion of olipudase alfa every 2 weeks for 9 years, or 
until olipudase alfa becomes commercially accessible (see maximum duration below), 
whichever comes first, unless the patient decides to enter another olipudase alfa clinical trial 
within the 9-year period prior to when olipudase alfa commercially accessible. 
x
The term “commercially accessible” is defined as when olipudase alfa is commercially 
accessible to each patient on an individual basis (eg, reimbursement being in place). The 
duration of study treatment with olipudase alfa between local Regulatory approval and 
commercial accessibility should not exceed 90 days. Therefore, as described below, after local 
Regulatory approval, the patient can continue in the LTS13632 study for a maximum of 
127 days.
x
This will ensure 90 days of study treatment with olipudase alfa for patients after local 
Regulatory approval and a safety follow up phone call 30 to 37 days after the last dose of 
study treatment. 
x
Notwithstanding the above, every pediatric patient will be treated in the LTS13632 study for 
at least 3 years. 
x
The patient can switch immediately after the end of study treatment to commercial treatment 
without any gap in order to ensure continuity of treatment with olipudase alfa. 
Data Monitoring Committee
A chartered, independent data monitoring committee (DMC) will provide ongoing expert, 
independent review of safety data to ensure the protection and safety of the patients, as described 
in Section 6.4.

The term “commercially accessible” is defined as when olipudase alfa is commercially 
accessible to each patient on an individual basis (eg, reimbursement being in place). The 
duration of study treatment with olipudase alfa between local Regulatory approval and 
commercial accessibility should not exceed 90 days.

at least 3 years. 
x
The patient can switch immediately after the end of study treatment to commercial treatment 
without any gap in order to ensure continuity of treatment with olipudase alfa. 
In the first 5 years, safety and efficacy assessments will occur at regular 3, 6, or 12 month 
intervals then only selected assessments will occur every 6 or 12 months after 5 years.  
Schedule of Assessments 
In the first 5 years, pharmacodynamic (PD) evaluations will occur every 3 months then every 
6 months after the cutoff date for a planned second database lock of the study for purpose of 
regulatory submissions in 2021. After 5 years, PD evaluations will occur every 12 months. 
PK evaluations will occur every 12 months only in the first 5 years and upon introduction of 
Process C(
) or Process C(
) at any time during the study. Beyond 5 years, pharmacokinetic 
testing will only occur upon the introduction of Process C(
) or Process C(
).  For Process 
C(
), if treatment is not interrupted, PK sample collection will take place at the patient’s last 
infusion under the current manufacturing scale and at the first infusion under Process C(
).  For 
introduction of Process C(
), if treatment is not interrupted, PK sample collection will take place 
at the second infusion under Process C(
).  In case reintroduction of olipudase alfa coincides 
with introduction of drug product from Process C(
) or Process C(
), PK samples will be 
collected at the infusion at which patients receive their usual dose of olipudase alfa under the new 
process. For schedule of PK assessment in adults, see Section 1.6, Table 11.
6.1.2
Post treatment period
For patients completing or discontinuing/withdrawing from the study, there will be a 
posttreatment period consisting of an end-of-treatment (EOT) visit 2 weeks (±7 days) after the last 
administered dose of study treatment and a safety follow-up phone call 30 to 37 days after the last 
administered dose of study treatment.

No formal interim analysis is planned for this study. A formal summary of data or interim CSR 
may be produced to support regulatory approval(s) and/or other submission/application 
requirement(s). 
6.3
DURATION OF STUDY PARTICIPATION
The length of a patient's participation will be from the time the informed consent form is signed 
until the last planned assessment/visit.  The approximate maximum study duration per patient is as 
follows:
x
Treatment period of 9 years or until olipudase alfa becomes commercially accessible (see 
maximum duration below), whichever comes first, unless the patient decides to enter 
another olipudase alfa clinical trial within the 9-year period prior to when olipudase alfa is 
commercially accessible. 
x
The term “commercially accessible” is defined as when olipudase alfa is commercially 
accessible to each patient on an individual basis (eg, reimbursement being in place). The 
duration of study treatment with olipudase alfa between local Regulatory approval and 
commercial accessibility should not exceed 90 days. Therefore, as described below, after 
local Regulatory approval, the patient can continue in the LTS13632 study for a maximum 
of 127 days.
x
This will ensure 90 days of study treatment with olipudase alfa for patients after local 
Regulatory approval and a safety follow up phone call 30 to 37 days after the last dose of 
study treatment. 
x
The patient can switch immediately after the end of study treatment to commercial 
treatment without any gap in order to ensure continuity of treatment with olipudase alfa. 
x
Notwithstanding the above, every pediatric patient will be treated in the LTS13632 study 
for at least 3 years.  
x
Follow up period concluded with a safety follow up phone call 30 to 37 days after the 
patient’s last infusion in the LTS13632 study. A safety follow-up phone call will also 
apply in case the patient switches immediately after the end of study treatment to 
commercial treatment.

STUDY COMMITTEES
An independent DMC, composed of members independent from the sponsor and the study 
investigators, is implemented in order to monitor patient safety by conducting formal reviews of 
accumulated safety data.  The DMC will provide the sponsor with appropriate recommendations 
on the conduct of the clinical trial to ensure the protection and safety of the patients enrolled in the
study (ie, exposure to study drug). All activities and responsibilities of the DMC are described in 
the DMC charter in compliance with applicable guidance (7).
Data monitoring committee meetings will occur at regular intervals as outlined in the DMC 
charter specific to this study.  The report of a potential dose-limiting toxicity to the sponsor or the 
occurrence of any safety-related issues identified by the sponsor's medical monitor or global 
safety officer that pose a medical concern, for example a fatal event, will result in the DMC 
holding an ad hoc review of the safety data and providing its recommendations to the sponsor 
regarding further patient treatment.

STUDY TREATMENTS
8.1
INVESTIGATIONAL MEDICINAL PRODUCT(S)
The study drug, olipudase alfa, is a sterile, white to off-white lyophilized cake supplied in 
single-use, 20 cc Type 1 glass vials. Each vial contains 20 milligrams of extractable olipudase 
alfa.
The study drug will be reconstituted with 5.1 mL of sterile water for injection to yield 
a concentration of 4.0 mg/mL of olipudase alfa.  The study drug will be further diluted in
0.9% sodium chloride for injection solution to a specific volume based on dose.
Detailed instructions on olipudase alfa preparation, storage, and administration are provided in the 
corresponding manual.
Refer to Section 8.5 for product handling and complaints reporting.
8.1.1
Treatments administered
Patients will receive olipudase alfa every 2 weeks (±3 days). Home infusions may be possible. To 
be eligible for home infusions, patients must meet the criteria in Section 10.2.1.
Patients will start this study at the same dose they were receiving at the end of their primary study, 
provided that they have not missed more than 1 biweekly dose between studies.  
All patients will have a visit 2 weeks (±3 days).  Quarterly visits will occur at the site. If the site 
visit is not possible due to site closure or extenuating circumstances that prevent an in-person site 
visit (eg, during COVID-19 pandemic) and home infusion is already approved for the eligible 
patient, quarterly visits will be done at home. Quarterly visit specific assessments that need a site 
visit will not be done at that time and will be done as unscheduled as soon as site visits become 
available. In such a case, some of the quarterly visit assessments may be done by home nurse 
(eg, lab sampling) and by the site through the phone (eg, Health-related quality of life 
instruments). Telehealth visits are an acceptable alternative to site visits, if site visits are not 
possible during a regional or national emergency declared by a governmental agency such as the 
COVID-19 pandemic due to site closure or extenuating circumstances that prevent an in-person 
site visit, in accordance with institutional policy and with applicable country-specific regulations.
Dose reintroduction regimens may be required for patients who have missed more than 1 dose 
between studies or during this study (LTS13632), depending on their usual dose.  For patients 
receiving home infusions who have missed 2 or fewer doses, the investigator can decide whether 
reintroduction should occur at the hospital/study site or via home infusion. For patients who have 
missed 3 or more doses ≥0.6 mg/kg, reintroduction of olipudase alfa should occur at the
hospital/study site. If the site visit is not possible during a regional or national emergency declared

by a governmental agency such as the COVID-19 pandemic due to site closure or extenuating 
circumstances that prevent an in-person site visit, reintroduction may be done via home infusion. 
Olipudase alfa reintroduction guidance will depend on the patient’s usual dose and the number of 
missed infusions: 
x
If a patient misses 1 dose, continue at the dose previous to the missed dose.
x
If a patient misses 2 doses:
-
If the previous dose was >0.6 mg/kg, the next dose must be 1 level below the last dose,
-
If the previous dose was ≤0.6 mg/kg, the next dose must be equal to the last dose.
x
If a patient misses 3 or more doses:
-
If the previous dose was >0.6 mg/kg, the next dose must be 0.3 mg/kg (0.3 mg/kg 
should be repeated at the subsequent infusion, similar to dose escalation schedule in 
the original study). Details will be provided in the study manual
-
If the previous dose was ≤0.6 mg/kg, the next dose must be equal to the last dose,
-
If a patient has missed 3 or more doses ≥0.6 mg/kg, reintroduction of olipudase alfa for 
patients receiving infusions at home should occur at the hospital/study site. 
-
If the site visit is not possible during a regional or national emergency declared by a 
governmental agency such as the COVID-19 pandemic due to site closure or 
extenuating circumstances that prevent an in-person site visit, reintroduction may be 
done via home infusion, if the patient has previously been approved for home infusion.
8.1.2
Route and method of administration
Patients will receive IV olipudase alfa over the same time period as in their original study. The 
length of the infusion time may be adjusted based on the patient’s tolerance of the infusion.
During the study, pediatric patients who reach adult age (18 years old) will receive the adult 
infusion volume.
See Section 8.1.5 for information on dose adjustments following dosing delays or missed doses.
8.1.3
Dosing considerations
Patients will receive the same olipudase alfa dose every 2 weeks, provided they have not missed 
more than 1 biweekly dose between studies.
Dosing will be based on an individual patient’s mass (ie, weight) as outlined in Section 8.1.1. For 
patients who participated in the DFI13412 study and who had a body mass index (BMI) >30, the 
dose will be based on the mass (in kilograms) corresponding to a BMI of 30 given the specific 
patient’s height.

8.1.4
Dose adjustments
Dose adjustments may also be considered at any time in consultation with the sponsor but may be 
recommended based on current safety or efficacy analysis results obtained from completed or 
ongoing studies of olipudase alfa.
8.1.5
Dosing delays or missed doses
Dose reintroduction regimens may be required for patients who have missed more than 1 dose 
between studies or during this study (LTS13632), depending on their usual dose. For patients 
receiving home infusions who have missed 2 or fewer doses, the investigator can decide whether 
reintroduction should occur at the hospital/study site via home infusion. For patients who have 
missed 3 or more doses ≥0.6 mg/kg, reintroduction of olipudase alfa should occur at the 
hospital/study site.  If the site visit is not possible due to site closure or extenuating circumstances 
that prevent an in-person site visit (eg, during COVID-19 pandemic), reintroduction may be done 
via home infusion, if the patient has previously been approved for home infusion. 
Patients who require dose reintroduction will have these assessments at each infusion until 
reaching their usual dose of olipudase alfa:
x
Before infusion: vital sign measurements, liver function tests (LFTs), hematology tests and 
safety biomarkers.
x
Immediately after infusion: vital sign measurements.
x
24 hours after infusion: vital sign measurements, LFTs, hematology and safety biomarkers
x
48 hours after infusion: vital sign measurements, LFTs and safety biomarkers. 
The 48 hours post-infusion assessments will no longer be assessed after the cutoff date for 
a planned second database lock of the study for purpose of regulatory submissions in 
2021.
During the dose escalation period, for transaminases assessed after infusion, if any AST or 
ALT value is >2x baseline and >ULN, the test should be repeated prior to the next scheduled 
infusion. Depending on the test results, the dose can be adjusted (repeated or reduced) or 
treatment can be withheld to allow additional transaminase monitoring, based on the 
physician’s clinical judgment.
Baseline is defined as the following: 
x
For initial dose escalation: last values prior to first dose of olipudase alfa
x
For dose re-escalation: last values prior to the first re-escalation dose

8.1.6
Dose stopping criteria
If any of the following AEs occur, dosing will be temporarily stopped for the specific patient who 
experienced the AE:
x
Any SAE, not related to the patient’s underlying condition and considered related to the 
study treatment.
x
Any increase in AST, ALT, total bilirubin, or alkaline phosphatase (AP) >3x baseline 
(prior to olipudase alfa therapy, ie, baseline value from the primary study) and > the upper 
limit of normal (ULN).
x
Any increase in total bilirubin or AP >1.5x baseline, in the presence of AST or 
ALT > 2 x ULN.
x
Any increase in ALT or AST >3 x ULN combined with an increase in ALT or 
AST >2x baseline (prior to olipudase alfa therapy), with symptoms of fatigue, nausea, 
vomiting, right upper quadrant pain or tenderness, fever, rash, or eosinophilia (>ULN).
x
Any AE that, in the opinion of the investigator or sponsor, raises significant concern 
regarding the safety of olipudase alfa at the administered dose.
8.1.7
Study interruption criteria
If either of these criteria are met,
x
2 patients develop the same severe AE that is not related to their underlying condition, or
x
A death occurs that is assessed as related or possibly related to olipudase alfa, an ad hoc 
DMC meeting will be held to review the safety data and provide its recommendations to 
the sponsor regarding further patient treatment.
After consideration of DMC recommendations, final decisions regarding discontinuation of study 
drug for all or selected clinical trial patients will be made by the Sponsor.
In the event a significant safety concern arises, the Sponsor may immediately decide to 
discontinue study drug dosing in all clinical trial patients prior to receipt of DMC 
recommendation.
If the study is temporarily or permanently halted, the Sponsor will notify the health authorities of 
the halt by a substantial amendment in regions where this applies.
8.1.8
Treatment discontinuation
A patient’s study treatment may be discontinued at any time at the patient’s request or at the 
discretion of the investigator or sponsor.  The following may be justifiable reasons for the 
investigator or sponsor to discontinue a patient from treatment:
x
The patient was erroneously included in the study (ie, was found to not have met the 
inclusion/exclusion criterion).

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 the 
sponsor.  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 the 
sponsor.  In this case, the investigator will be responsible for promptly addressing any request 
made by the sponsor 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.
8.5.1
Treatment accountability and compliance
Compliance to the treatment regimen will be monitored in terms of the percentage of scheduled 
infusions the patient receives through the treatment period. No infusions should be missed. 
Noncompliance is defined as missing 2 consecutive infusions or 4 total infusions per each 
12-month period throughout the treatment period. As they are identified, the investigator should 
discuss noncompliant patients on a case by case basis with the sponsor’s medical monitor 
(or designee).
8.5.2
Return and/or destruction of treatments
Reconciliation of study drug must be performed at the site by the investigator and the monitoring 
team using treatment log forms and documented on center study drug inventory countersigned by 
the investigator and the monitoring team.
If appropriate, a written authorization for destruction will be provided by the sponsor clinical trial 
team once the reconciliation is achieved.  Investigational medicinal product destruction may be 
performed at the site depending on study drug specificities and local requirements; alternatively, 
study drug may be returned to the sponsor for destruction.
8.6

Page 86
During the study, prohibited medications include those that may decrease olipudase alfa activity 
(eg, chlorpromazine, tricyclic anti-depressants [eg, imipramine or desipramine]). See the most 
recent version of the study manual for a list of concomitant medications that may decrease 
olipudase alfa activity.
Cationic amphiphilic antihistamines, such as loratadine, desloratadine, astemizole, ebastine, 
terfenadine, and clemastine, may decrease olipudase alfa activity. Therefore, the need for their use 
in oral or IV administration should be carefully considered. There is no restriction on topical
antihistamines.
Certain medications and herbal supplements can be hepatotoxic or can cause or prolong bleeding, 
and should not be taken within 10 days before and 3 days after the biopsy procedure (only patients 
who previously participated in the DFI13412 study). Potentially hepatotoxic medications or herbal 
supplements include, but are not limited to, 3-hydroxy-3-methylglutaryl-coenzyme A reductase 
inhibitors, erythromycin, valproic acid, antidepressants, kava, and echinacea. Medications that 
may cause or prolong bleeding include, but are not limited to, anticoagulants, ibuprofen, aspirin, 
garlic supplements, ginkgo, and ginseng.
These lists of prohibited medications and herbal supplements may be incomplete. The investigator 
may also prohibit medications and products not listed here. Therefore, the investigator must 
review all medications and products for every patient. For more information on medications and 
herbal supplements that may decrease olipudase alfa activity or may be hepatotoxic, refer to the 
most recent version of the study manual.
Pretreatment in general is not recommended for prophylactic management of IARs.  For patients 
who experience moderate to severe or recurrent IARs (as defined in Section 10.5.1.3.2) suggestive 
of hypersensitivity, pretreatment regimens (eg, antihistamines, antipyretics, glucocorticoids) may 
be prescribed by the investigator as per clinical judgment.  In particular, the need for cationic 
amphiphilic antihistamines administered orally or IV should be carefully considered given the 
potential risk for functional inhibition of olipudase alfa activity by such drugs.
8.6.1
Treatment of infusion-associated reactions
For management of mild IARs, infusion rate reductions (eg, reduced to half the rate) or temporary 
interruptions may mitigate the reaction.  For moderate to severe or recurrent IARs, the 
investigator may consider the use of pretreatment medications (eg, antihistamines, antipyretics, 
and/or glucocorticoids), if the symptoms are suggestive of hypersensitivity reaction, in addition to 
infusion rate reductions, interruptions, or discontinuation.  In particular, the need for cationic 
amphiphilic antihistamines administered orally or IV should be carefully considered given the 
potential risk for functional inhibition of olipudase alfa activity by such drugs.
Patients experiencing symptoms suggestive of hypersensitivity reactions, including anaphylactic 
or anaphylactoid reactions, during olipudase alfa infusion should be managed according to the 
general standards of care consistent with the treatment of such reactions. If anaphylaxis or other 
severe allergic reactions occur, immediate discontinuation of the infusion should be considered, 
and appropriate medical treatment should be initiated.  Because of the potential for severe IARs, 
appropriate medical personnel and equipment to perform resuscitation must be readily available in 
the event of a hypersensitivity reaction.

The clinical laboratory data consist of blood analyses (clinical chemistry, LFTs, hematology, 
coagulation studies) urinalysis, and for women of childbearing potential only, a urine pregnancy 
test.  Values will be converted into standard international units and then analyzed. International 
units will be used in all listings and tables.
Acute phase reactions and CRS are associated with changes in specific clinical laboratory 
parameters (Section 10.5.1.3.2).
The following clinical laboratory test results will be assessed by the site as specified in 
Section 1.1 through Section 1.5.
x
Clinical chemistry: Sodium, potassium, calcium, chloride, blood urea nitrogen, creatinine, 
lactate dehydrogenase, total protein, albumin, glucose, cholesterol, phosphorus, and

9.1.15 Immune response assessments
Samples will be collected as specified in Section 1.1 through Section 1.5 for the evaluation of 
anti-olipudase alfa IgG antibodies.   If introduction of a drug product from Process C(
) or from 
Process C(
) occurs, testing will occur monthly for the first 6 months after introducing the drug 
product from Process C(
) or Process C(
).  If seroconversion occurs, patients will also be 
tested for neutralizing antibodies to olipudase alfa.
In the event that a patient reports an IAR that is suggestive of a hypersensitivity reaction (as 
described in Section 10.5.1.3.2.1) and is of:

the sponsor for anti-olipudase alfa antibody (IgG and IgE), tryptase activity, and 
complement activation testing as described below.  Skin testing may also be performed if 
a hypersensitivity reaction is suspected.
x
For IgE anti-olipudase alfa antibody testing the same predose serum sample drawn for 
anti-olipudase alfa IgG testing may be used if the IAR occurs at that study visit.  If 
a predose sample was not drawn on that day, the patient should return to the study site at 
least 3 days after the event for a serum sample to be drawn.  Testing is conducted for 
research purposes to gain additional information as to individual patients’ responses to 
study treatment and for aiding in the clinical management of patient safety.

EFFICACY ASSESSMENTS
The efficacy assessments (secondary endpoints) are described in Section 9.2.1 through 
Section 9.2.9.  These include improvements in spleen and liver volume (as measured by 
abdominal MRI), pulmonary imaging by HRCT and chest X-ray (at selected sites) (for ILD
scores), PFTs, hematology, lipid profiles, adult health outcome questionnaires, pediatric health 
outcome questionnaires, and for pediatric patients only, hand X-rays, Tanner staging, and linear 
growth by height Z-score.
Refer to the study flow charts in Section 1.1 through Section 1.6 for the timing of these 
assessments throughout the study.  Efficacy analyses are described in Section 11.6.2.
9.2.1
Abdominal magnetic resonance imaging
Spleen and liver volumes will be assessed by abdominal MRI to quantify the degree of 
splenomegaly and hepatomegaly at the time points specified in Section 1.1 through Section 1.5.
Upon a manufacturing scale change, an abdominal MRI will be performed at the first 6-months 
visit after the change if that 6-months visit is not a 12-months visit where the assessment is 
already scheduled.  Patients are required to fast from solid foods (liquids, such as water, milk, and 
juice, are allowed) for 6 hours prior to the MRI to reduce the effect of a meal.
The MRIs will be collected and read centrally by a third party blinded to patient number and study 
visit.  Procedures for MRI are detailed in the corresponding manual.
9.2.2
Pulmonary imaging
9.2.2.1
High-resolution computed tomography
High-resolution computed tomography scans of the chest will be obtained as specified in 
Section 1.1 through Section 1.5 to quantify the degree of possible ILD.
High-resolution computed tomography will be performed using methods that are compatible with 
the standard institutional procedures of the investigational site.  Images will be collected centrally 
by a medical imaging core laboratory where they will be digitized and coded and read by a third 
party blinded to patient number and study visit.  The mean density will be calculated at each lung 
level using standard HRCT software.  The lung fields will be assessed by a central reader and 
scored subjectively for the degree of ILD (0 = normal, 1 = mild, 2 = moderate, or 3 = severe) (8).
The bilateral lung boundaries are determined from the following 4 pre-defined levels on the 
HRCT images (8).
x
Level 1 includes the aortic arch.
x
Level 2 includes the carina.
x
Level 3 is midway between the carina and 1 centimeter above the hemidiaphragm.

Procedures for HRCT scans are detailed in the corresponding manual.
9.2.2.2
Chest X ray
A chest X-ray (posterior-anterior and lateral views) will be performed at selected sites as indicated 
in Section 1.1 through Section 1.5.
A study site physician, such as the investigator, a pulmonologist, or a radiologist, should review 
the chest X-ray in a timely manner to determine whether there are any safety concerns and for
clinical management of the patient.  Chest X-rays will be collected at the site and sent to a 
medical imaging core laboratory where they will be digitized (if not already done at the site), 
coded, and read by a third-party reader blinded to patient number and study visit.  The lung fields 
will be scored subjectively for the degree of ILD (8):
x
0 = No infiltrative lung disease.
x
1 = Mild (affecting 1% to 25% of the lung volume).
x
2 = Moderate (affecting 26% to 50% of the lung volume).
x
3 = Severe (affecting 51% to 100% of the lung volume).
Procedures for chest X-ray scoring are detailed in the corresponding manual.
9.2.3
Pulmonary function tests
Pulmonary function tests will be performed in all patients previously enrolled in the DFI13412 
study, and in patients for whom it was done in the DFI13803 study, to measure lung volumes, air 
flow, and gas exchange for evidence of ILD at the time points specified in the study flow charts in 
Section 1.1 through Section 1.5.  Completion of PFTs may depend on patient age or cooperation, 
or both.
Upon a manufacturing scale change, PFTs will be performed at the first 6-month visit after the 
change if that 6-month visit is not a 12-month visit where the assessment is already scheduled.  
The pulmonary function test (PFT) administration protocol is standardized across sites in 
accordance with American Thoracic Society/European Respiratory Society guidelines (9, 10).
Pulmonary function testing will include, but will not be limited to, assessment of forced vital

total lung capacity.  Diffusing capacity of carbon monoxide (DLCO) will be used to measure gas 
exchange across the alveolocapillary membrane.  Pulmonary function tests should occur at the 
same time of day across study visits (±2 hours of the time of day of the first assessment).
Patients who routinely take bronchodilators must withhold bronchodilators before routine PFTs as 
follows:
x
Short-acting inhaled or oral bronchodilators (eg, albuterol) - 8 hours.
x
Medium-acting inhaled bronchodilators (eg, atrovent) - 12 hours.
x
Long-acting inhaled or oral bronchodilators (eg, salmeterol) - 24 hours.
The equipment will be part of the institution’s quality control/assurance program with regard to 
validation and calibration.  The equipment is calibrated the day of the testing.  A log will be kept 
and a copy will be submitted to the sponsor at the completion of the study.  Where possible, the 
same equipment will be used for all measurements.
A specialist trained in the interpretation of this test should review the PFTs in a timely manner for 
clinical management of the patient.
9.2.4
Hematology
Hemoglobin and platelet counts will be assessed as safety and as efficacy parameters, as ASMD 
results in hematologic disorders.  An additional blood sample will be obtained for hemoglobin and 
platelet count at least 24 hours and up to 2 weeks apart from the sample collected for clinical 
laboratory tests at the time points specified in Section 1.1 through Section 1.5.
9.2.5
Fasting lipid profile
A fasting lipid profile will be assessed as an efficacy parameter, as ASMD results in the 
progressive accumulation of lipids.
Blood will be collected prior to infusion for fasting lipids (including, but not limited to, total 
cholesterol, LDL-cholesterol (LDL-C), HDL-cholesterol (HDL-C), VLDL-cholesterol (VLDL-C),
triglycerides, ApoB, apolipoprotein A1, and lipoprotein [a]) at the time points specified in

performed the assessments in DFI13803.  Completion of these assessments may depend on patient 
age or cooperation, or both.
Assessment time points are specified in Section 1.3 and Section 1.4. Refer to the study operations 
manual for further details.
9.3.3
Cycle ergometry
Cycle ergometry will be performed at the time points specified in Section 1.1.  Completion of the 
assessment may depend upon patient cooperation.
Cardiopulmonary status will be assessed using a stationary 1-wheeled cycle as an ergometer to 
measure a person's work output under controlled conditions.  Patients will be asked to ride the 
cycle at increasing workload levels until they can no longer proceed.  Patients will breathe 
through a tube connected to a 1-way valve for continuous measurements of oxygen (O2) uptake, 
carbon dioxide (CO2) output, and tidal volume throughout the test.  Heart rate, respiratory rate, 
and digital O2 saturation will also be continuously monitored.  Steady-state levels for each 
workload will be calculated for O2 uptake, CO2 output, tidal volume, ventilation, and respiratory 
exchange ratio.  The maximum workload achieved will be recorded and expressed as percent 
predicted.  In addition, percent predicted maximum will be calculated for O2 uptake, heart rate, 
and tidal volume. Note that cycle ergometry assessments must occur at the same time for each 
assessment (ie, ±2 hours of the time of day of the first assessment).
Procedures for cycle ergometry assessments are detailed in the corresponding manual.

Pharmacokinetics
For both adult and pediatric patients, PK testing will only occur yearly for the first 5 years and 
upon the introduction of Process C(
) or Process C(
) at any time during the study.  For Process 
C(
), if treatment is not interrupted, PK sample collection will take place at the patient’s last 
infusion under the current manufacturing scale and at the first infusion Process C(
). For 
introduction of drug product from Process C(
),if treatment is not interrupted, PK sample 
collection will take place at the second infusion under Process C(
).  In case reintroduction of 
olipudase alfa coincides with introduction of a drug product from Process C(
) or Process C(
), 
PK samples will be collected at the infusions at which patients receive their usual dose of 
olipudase alfa under the new process.
Blood samples for pediatric patients are drawn at different intervals than samples in adult patients 
(Section 1.6, Table 12 and Table 11, respectively) and in different volumes (Section 9.5).

Pharmacokinetic sampling and parameters in adults
9.3.8.3.1 Sampling time in adults
Pharmacokinetic sampling will occur at the time points listed in Section 1.1 and Section 1.6.
Specific time points are detailed in Table 11. If a patient receives only a partial infusion (eg, due 
to a safety concern), PK sampling will be repeated the next time the patient receives that dose. If 
a repeat is required, all PK time points will be repeated.
Windows around PK blood samples are ±10 minutes for collection times less than 8 hours and 
±3 hours for collection times of 8 hours or longer post infusion.
Blood samples may be drawn for PK assessments using an indwelling catheter from an arm that is 
not used for dose administration. The exact time of dose administration (start and stop times of 
infusion), rate of infusion, and dose will be recorded along with exact sampling times.
If a manufacturing scale change occurs, serial blood samples for PK will be collected at all of the 
same time points with the last infusion of olipudase alfa produced at the original scale and with 
the first infusion of olipudase alfa produced at the new scale. For introduction of drug product 
from Process C(
), PK sample collection will only take place at the second infusion under 
Process C(
).

Pharmacokinetic sampling and parameters in pediatric patients
9.3.8.4.1 Sampling time in pediatric patients
Pharmacokinetic sampling will occur at the time points listed in Section 1.3 through Section 1.6.
Specific time points are detailed in Table 12 for each age group.  To minimize the amount of 
blood drawn, post dose time points have been selected for sparse sampling of PK parameters.
If a patient receives only a partial infusion (eg, due to a safety concern), PK sampling will be 
repeated the next time the patient receives that dose. If a repeat is required, all PK time points will 
be repeated.
In adolescent patients, windows around PK blood samples are ±10 minutes for collection times 
<8 hours and ±3 hours for collection times ≥8 hours post infusion.
Depending on patient age, blood samples may be drawn for PK assessments using an indwelling 
catheter from an arm that is not used for olipudase alfa infusions. The exact time of olipudase alfa 
infusions (start and stop times of infusion), rate of infusion, time of infusion rate changes, and 
dose will be recorded along with exact sampling times.

Pharmacodynamic assessments
Only patients who previously participated in the DFI13412 study will have PD assessments for 
clearance of sphingomyelin accumulation in liver tissue.  All patients will be assessed for 
metabolite levels in plasma and/or DBS, as well as plasma ceramide.
9.3.9.1
Liver biopsy for sphingomyelin in liver tissue (only patients who previously 
participated in the DFI13412 study
Liver biopsy samples will be evaluated for sphingomyelin accumulation and liver pathology in the 
patients who previously participated in the DFI13412 study who were at least 18 years old when 
they entered in the study.  Patients who were younger than 18 years old when they entered the 
study will not have liver biopsies.  See Section 9.1.12 for details about liver biopsies.
9.3.9.2
Metabolite levels in plasma and dried blood spot (all patients)
Metabolite levels (eg, sphingomyelin, lyso-sphingomyelin) in plasma and/or DBS will be 
quantified by the sponsor (or designee) using samples collected as detailed in the study flow chart 
in Section 1.1 through Section 1.5. Procedure, preparation, and sample shipment guidelines for 
plasma and DBS sampling are provided in the corresponding manual.
9.3.9.3
Plasma ceramide (all patients)
Plasma ceramide will be quantified at the time points shown in the flow chart in Section 1.1
through Section 1.5.  Plasma ceramide is also being tested as a safety biomarker.

APPROPRIATENESS OF MEASUREMENTS
The safety, efficacy, and PK/PD measurements in this trial are accepted methods for assessing 
patient safety and outcomes.
9.5
SAMPLED BLOOD VOLUME
For all pediatric patients, no more than 7 mL/kg of blood will be collected during any 8-week 
period.  Additional blood samples may be collected at the investigator’s discretion for patient 
safety monitoring.
If a PK or IgG sample collection for the planned introduction of drug product from Process C(
) 
was erroneously taken, the future sample collection will be adjusted according to the blood 
volume allowed per each age cohort in order to avoid excessive blood withdrawal. For specific 
details, please refer to Study Manual.

FUTURE USE OF SAMPLES
For patients who have consented to it, left over samples following testing may be used for other 
research purposes (excluding genetic analysis) related to ASMD. These samples will be stored for 
15 years after end of the study in compliance with applicable country-specific regulations.
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 labeled with the same identifiers as the ones used during the study 
(ie, subject ID).  They will be transferred to a Sanofi site (or a subcontractor site) which can be 
located outside of the country where the study is conducted.  The sponsor has included safeguards 
for protecting subject confidentiality and personal data (Section 14.3 and Section 14.5,
respectively).

STUDY PROCEDURES
10.1
VISIT SCHEDULE
Section 1.1 through Section 1.5 summarize the schedules of study events for all patients enrolled 
into this study.  Individual assessments are described in Section 9.
10.2
STUDY PROCEDURES
Infusions will take place at the study site, or for some patients, at home.
10.2.1 Home infusions
Home infusion may be possible.  Patients must meet the eligibility requirements outlined below.  
In addition, the investigator and the sponsor must agree that home infusion is appropriate.  
To receive home infusions, the following criteria must be met:
x
The investigator must agree in writing that home infusion is appropriate for the patient.
x
The patient, or the pediatric patient’s parent(s) or legal guardian(s), must be willing and 
able to comply with home infusion procedures.
x
The patient must, in the investigator’s (or designee’s) opinion, have been clinically stable 
with no history of moderate or severe IARs for at least 6 months, and must be on a stable 
olipudase alfa dose.  No infusion rate increases will be allowed while a patient is receiving 
home infusions.
x
The patient must have no ongoing (not yet recovered) SAEs that, in the opinion of the 
investigator, may affect the patient’s ability to tolerate the infusion.
x
Home infusion infrastructure, resources, and procedures must be established and available 
according to applicable regional regulations.
x
For patients experiencing an IAR while being infused at home, the investigator should 
assess whether or not it is safe for the patient to continue to be treated via home infusion or 
return to the study site for their following infusion and when the patient would be ready to 
resume home infusion. In case home infusion continues, the investigator will guide the 
home infusion staff on the measures to be followed for subsequent infusion to manage the 
IAR (eg, infusion interruption, premedication, change the infusion rate, etc. See Treatment 
of infusion-associated reactions in Section 8.6.1.
x
If recurrent IARs or hypersensitivity reactions occur, the investigator should assess 
whether or not it is safe for the patient to continue to be treated via home infusion.
x
If a severe hypersensitivity reaction or an anaphylaxis reaction occurs, during an infusion 
given at home, treatment will be discontinued immediately, and appropriate medical

until the investigator agrees with the sponsor that it is safe for the patient to continue to be 
treated via home infusion. See Section 8.6 for details on severe hypersensitivity and 
anaphylaxis management.
x
For the switch from Process C(
) IMP to Process C(
) IMP, if the site visit is possible, 
the patient should  receive the first infusion at the site. However, if the site visit is not 
possible during a regional or national emergency declared by a governmental agency such 
as the COVID-19 pandemic due to site closure or extenuating circumstances that prevent 
an in-person site visit, the first infusion of the Process C(
) IMP is allowed during home 
infusion for eligible patients in agreement between the Sponsor and the Investigator in 
compliance with applicable country-specific regulations.
x
Prior to beginning home infusions, the home infusion staff, including new staff members, 
must have been appropriately trained and/or licensed, if applicable, on proper procedures 
to prepare and administer infusions, monitor patients, document procedures, and report to 
site on a timely basis.
x
The home infusion staff must have access to and be trained on proper use of safety 
equipment, including, but not limited to, cardiopulmonary resuscitation equipment.
x
Home infusion staff must keep source documentation of the infusion, including 
documentation of any AEs.  Home infusion staff must be amenable to providing specific 
source documentation to Sanofi Genzyme and agree to be monitored.  The Principal 
Investigator is still responsible for all study procedures and patient’s safety even when 
delegating infusion responsibilities to the home care company.
x
An additional questionnaire about home infusion experience may be added any time 
before end of the study for patients who received home infusion treatment for total time of 
at least of one year.
10.2.2 Alcohol consumption
Patients must be willing to abstain from the use of alcohol for 1 day prior to and 3 days after each 
study drug infusion (see Section 7.2).
Patients will be counseled to limit alcohol consumption during the study:
x
Male patients to a maximum of 30 grams of alcohol per day (2 drinks/day).
x
Female patients to a maximum of 15 grams of alcohol per day (1 drink/day).
Patients who do not limit alcohol can be discontinued from the study according to investigator’s 
discretion.
10.2.3 Pregnancy and contraception
Female patients of childbearing potential are required to have a negative urine β-HCG pregnancy 
test before enrolling in the trial and every 4 weeks prior to undergoing visit specific assessments 
and receiving olipudase alfa.

10.2.3.1 Pregnancy
Pregnancy will lead to treatment discontinuation in all cases.  No studies of olipudase alfa have 
been conducted in pregnant women.  To ensure patient safety for this study, all female patients of 
childbearing potential must have a negative urine β-HCG pregnancy test every 4 weeks.
Female patients of childbearing potential and sexually mature male patients must be willing to 
practice true abstinence, or use 2 acceptable, effective methods of contraception.  Every effort will 
be made to prevent pregnancy during this study.  In all cases, the sponsor must be notified of all 
terminations to treatment as soon as possible and, if applicable, the date of withdrawal from the 
study must be recorded in the CRF and in the patient’s medical record.  If possible, all tests and 
evaluations listed for the end of study visit will be carried out.  If a patient fails to return for the 
necessary visits, then every effort must be made to contact the patient and determine the reason(s), 
which will be recorded on the CRF.
Female patients will be instructed to notify the investigator immediately if they discover they are 
pregnant.  Male patients will be instructed to notify the investigator immediately if they discover 
that their sexual partner is pregnant.
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 10.5.2.3.1 for female patients on the 
study to contact Global Pharmacovigilance and Epidemiology (GPE) within 24 hours. For female 
partners of male patients on the study, the pregnancy form will be used to report the pregnancy to 
Global Pharmacovigilance and Epidemiology (GPE) within 24 hours. Follow-up of the pregnancy 
is mandatory until the outcome has been determined. The progress of the pregnancy must be 
followed until the outcome of the pregnancy is known (ie, delivery, elective termination, or 
spontaneous abortion).  If the pregnancy results in the birth of a child, additional follow-up
information may be requested.
The investigator will be asked to obtain follow-up information after the gestational period to 
obtain maternal/fetal/neonatal outcome and any other relevant information.
Follow-up information may be requested at additional time points. All study related visits/contacts 
involving a known pregnancy should include pregnancy status assessment until pregnancy 
outcome is known.
If a female patient is discontinued because of pregnancy, pregnancy will be documented as the 
reason for study discontinuation.  Spontaneous abortions and stillbirths are reported as SAEs, and 
the investigator should follow the instructions in Section 10.5.2.2.
10.2.3.2 Contraception
Female patients of childbearing potential and sexually mature male patients are required to
practice true abstinence in line with their preferred and usual lifestyle or use 2 acceptable effective 
methods of contraception, a barrier method such as a condom or occlusive cap (diaphragm or 
cervical/vault cap) with spermicidal foam/gel/film/cream/suppository and an established 
nonbarrier method such as oral, injected, or implanted hormonal methods, an intrauterine device,

or an intrauterine system for the duration of the study, and for at least 15 days after the last dose 
of study drug.
Female patients will be considered capable of bearing children unless they have not yet had 
menarche, had a hysterectomy or bilateral oophorectomy, or have undergone menopause (ie, are 
≥50 years old without menses for ≥1 year or are <50 years old with confirmed ovarian failure).
10.3
DEFINITION OF SOURCE DATA
Source data includes all information in original records and certified copies of original records of 
clinical findings, observations, or other activities necessary for the reconstruction and evaluation 
of the trial.  Source data are contained in source documents.
Source documents are original documents, data and records (eg, hospital records, clinical and 
office charts, laboratory reports and notes, memoranda, patient diaries or evaluation checklists, 
pharmacy dispensing records, recorded data from automated instruments, copies or transcripts 
certified after verification as being accurate and complete, microfiches, photographic negatives, 
microfilm or magnetic media, X-rays, patient files, and records kept at the pharmacy, at the 
laboratories, and at medical-technical departments) involved in the clinical study. Source 
documentation must be maintained to support information provided in the CRF.
All protocol-required information collected during the study must be recorded by the investigator 
or other study personnel in the source documentation for the study. The source documentation 
will be used to enter the protocol-required information into the CRF. No data should therefore be 
directly entered into the CRF.
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 stopped, it should be 
determined whether the stop can be made temporarily; permanent IMP discontinuation should be 
a last resort.  Any IMP discontinuation should be fully documented in the source and CRF.  In any 
case, the patient should remain in the study as long as possible.
Pregnancy will lead to treatment discontinuation in all cases.  Sexually active female patients of 
childbearing potential and sexually active male patients who permanently discontinue must use 
2 forms of contraception for at least 15 days after their last dose.
10.4.1 Temporary treatment discontinuation with investigational medicinal product(s)
Temporary treatment discontinuation, decided by the investigator, corresponds to more than 
1 dose not administered to the patient.  Dose reintroduction regimens may be required for patients 
who have missed more than 1 dose between studies, depending on their usual dose.
For patients receiving home infusions who have missed 2 or fewer doses, the investigator can 
decide whether reintroduction should occur at the hospital/study site or via home infusion. For

Page 118
patients who miss 3 or more doses ≥0.6 mg/kg, reintroduction of olipudase alfa should occur at 
the hospital/study site. If the site visit is not possible due to site closure or extenuating 
circumstances that prevent an in-person site visit (eg, during COVID-19 pandemic), 
reintroduction may be done via home infusion. 
The investigator, in consultation with the sponsor, will determine whether the patient will be 
redosed.  Reintroducing patients to olipudase alfa treatment will take into account the patient’s 
usual dose, the number of missed infusions, and the patient’s ability to tolerate the dose.
Upon reintroduction of treatment, certain assessments will be repeated at infusions 
(Section 8.1.5). The investigator will decide if additional specific assessments may be required 
before the patient can begin the reintroduction regimen.
Olipudase alfa reintroduction guidance is described in Section 8.1.1. Reintroduction of olipudase 
alfa treatment will be done with appropriate monitoring at the discretion of the investigator and 
confirmation that the patient still meets the study criteria (Section 7.1 and Section 7.2).
The duration of all temporary treatment discontinuations should be recorded by the investigator in 
the appropriate screens of the CRF.
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, sponsor, or the patient not to re-expose the patient to the 
IMP at any time.
10.4.3 List of criteria for permanent treatment discontinuation
Patients may withdraw from treatment at any time and irrespective of the reason.  The investigator 
may also decide to withdraw a patient from treatment.
Patients should discontinue the IMP for the following reasons:
x
Unacceptable toxicity.
x
The need for intervention or therapy precluded by protocol, and determination by the 
investigator that it is medically necessary to do so.
x
The patient was unable to comply with the requirements of the protocol.
x
The patient wishes to be withdrawn from treatment.
x
The patient was erroneously included in the study (failed to satisfy all study criteria in 
Section 7).
x
The patient participated in another investigational study without the prior written 
authorization from the sponsor.
x
The patient is no longer deriving clinical benefit, in the opinion of the investigator.
x
Pregnancy.

Page 119
In addition, the sponsor may decide to discontinue the trial prematurely for any other reason.
Any relevant abnormal laboratory value or ECG parameter will be immediately rechecked for 
confirmation before making a decision of permanent discontinuation of the IMP for the concerned 
patient.
Patients who received at least 1 dose of study drug and who are withdrawn from the study will be 
asked to complete all discontinuation assessments before withdrawal (as detailed in Section 1.1,
Section 1.2, Section 1.4 and Section 1.5).  They will also receive a safety follow-up telephone call 
from the study site 30 to 37 days after the final administration of study drug.  If a patient fails to 
return for the necessary visits, every effort must be made to contact the patient to determine the 
reason(s).  The investigator will document the reason(s) for treatment discontinuation/study 
withdrawal on the CRF and in the patient’s medical record.  In all cases, the sponsor must be 
notified of all study terminations as soon as possible.
10.4.4 Handling of patients after permanent treatment discontinuation
Patients or parent/legal guardians who decide to discontinue participation in the study should be 
contacted by the study investigator in order to obtain information about the reason(s) for 
discontinuation and collection of any potential AEs.
When possible, all tests and evaluations listed in Section 1.1, Section 1.2, Section 1.4 and 
Section 1.5 for the post treatment withdrawal visit should be carried out within 2 weeks of the last 
olipudase alfa infusion.  If a patient fails to return for the necessary visits, every effort must be 
made to contact the patient and determine the reason(s) and record the reason(s) on the CRF.
In all cases, the sponsor must be notified of all study terminations as soon as possible and the 
reason for and date of withdrawal from the study must be recorded in the CRF and in the patient’s 
medical record.
10.4.5 Procedure and consequence for patient withdrawal from study
Patients may withdraw from the study before study completion if they decide to do so, at any time 
and irrespective of the reason.  Preferably the patient should withdraw consent in writing and, if 
the patient refuses or is physically unavailable, the site should document and sign the reason for 
the patient’s failure to withdraw consent in writing.
The reason for withdrawal should be captured.  Patients who withdraw should be explicitly asked 
about the contribution of possible AEs to their decision to withdraw consent, and any AE 
information elicited should be documented.
Patients who withdraw should be asked to come back for the end of study visit and will receive 
the safety follow phone call.
For patients who fail to return to the site, the investigator should make the best effort to contact 
the patient (eg, contacting patient’s family or private physician, reviewing available registries or 
health care databases), 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 (SAP) will specify how these patients lost to follow-up for their 
primary endpoints will be considered.
10.5
OBLIGATION OF THE INVESTIGATOR REGARDING SAFETY REPORTING
The investigator is the primary person responsible for making all clinically relevant decisions on 
safety issues.
Any abnormal findings that meet the definition of an AE per Section 10.5.1 will be recorded on 
the CRF.  The investigator will continue to monitor the patient until the parameter returns to 
baseline or until the investigator determines that follow-up is no longer medically necessary.
All AEs (as described in Section 10.5.1) regardless of seriousness or relationship to study 
treatment will be collected from the time of written informed consent until the patient completes 
participation in the study as defined in Section 6.3.1.  Adverse events that started during the 
previous study which are ongoing at the time the patient signs the written informed consent 
should be reported in this study.
All SAEs (as described in Section 10.5.1.2) and any AESI requiring immediate notification 
(as described in Section 10.5.2.3.1) including those ongoing at the time of study completion) will 
be monitored until resolution, stabilization of the condition, or until it is mutually agreed upon by 
both the investigator and the sponsor safety physician to discontinue.
If, at any time after the patient has completed participation in the study (as defined in 
Section 6.3.1), the investigator or study staff becomes aware of an SAE that they believe is 
possibly related or related to IMP, then the event and any known details should be reported 
promptly to the sponsor.  Follow the reporting instructions in Section 10.5.2.2.
All AEs diagnosed by the investigator will be reported per applicable regulations and guidelines.  
Definitions for AEs, SAEs, AESI; and instructions for AE monitoring and reporting, are provided 
in Section 10.5 through Section 10.8. All AEs will be coded using the version of Medical 
Dictionary for Regulatory Activities (MedDRA) currently in effect at the time of the considered 
database lock.
The investigator is responsible for reviewing and signing all laboratory reports. Any abnormal 
findings that meet the definition of an AE per Section 10.5.1 will be recorded on the CRF. The 
investigator will continue to monitor the patient until the parameter returns to baseline or until the 
investigator determines that follow-up is no longer medically necessary.

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
An SAE is any untoward medical occurrence that at any dose:
x
Results in death, or
x
Is life-threatening (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), or
x
Requires inpatient hospitalization or prolongation of existing hospitalization, or
x
Results in persistent or significant disability/incapacity, or
x
Is a congenital anomaly/birth defect.
x
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 
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 conditions have to be considered as medically important events.  The list is not 
intended to be exhaustive:
x
Intensive treatment in an emergency room or at home for:
-
Allergic bronchospasm,
-
Blood dyscrasias (ie, agranulocytosis, aplastic anemia, bone marrow aplasia, 
myelodysplasia, pancytopenia, etc),
-
Convulsions (seizures, epilepsy, epileptic fit, absence, etc).
x
Development of drug dependency or drug abuse.
x
Suicide attempt or any event suggestive of suicidality.
x
Syncope, loss of consciousness (except if documented as a consequence of blood 
sampling).
x
Bullous cutaneous eruptions.

Cancers diagnosed during the study.

Chronic neurodegenerative diseases if newly diagnosed and not part of the ASMD 
spectrum.
10.5.1.3 Adverse event of special interest
An AESI is an AE (serious or nonserious) of scientific and medical concern specific to the 
sponsor’s product or program, for which ongoing monitoring and rapid communication by the 
investigator to the sponsor may be appropriate.  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.  Reporting guidelines and follow-up instructions 
are provided below.
AESIs include pregnancy, IARs (hypersensitivity reactions, APRs, and CRSs).
10.5.1.3.1Pregnancy
Pregnancy of a female patient entered in the study, and pregnancy occurring in a female partner of 
a male patient entered in this study.  See Section 10.2.3.1 for details.
10.5.1.3.2Infusion-associated reactions
Some AEs may be manifestations of IARs, including hypersensitivity reaction, APR, and CRS.  
However, original signs and symptoms must be reported as AEs.  In the CRF, investigators are 
asked to identify whether a specific AE represents a clinical manifestation of the IAR.
Infusion-associated reactions are defined as AEs that occur during the infusion or within up to 
24 hours after the start of infusion and are considered as related or possibly related to the study
treatment by the investigator or the sponsor.  An event occurring ≥24 hours after the start of 
an infusion may be judged an IAR at the discretion of the investigator or sponsor.  For this study 
of olipudase alfa, IARs may present as different types of reactions, such as hypersensitivity 
reactions, APRs, and CRS.
10.5.1.3.2.1
Hypersensitivity reactions
Infusion-associated hypersensitivity reactions seen with other enzyme replacement therapies are 
typically immunoglobulin-mediated (IgG/IgE) and occur after sensitization. After subsequent 
exposure to the antigen typically early into or shortly after the infusion, a “sensitized” patient may 
experience a broad range of allergic reactions that can be mild to severe or life-threatening.  
Anaphylaxis (or anaphylactic reaction) is a serious, IgE mediated allergic reaction that is rapid in 
onset, and may cause death (22). Anaphylactoid, or non-immunologic anaphylaxis, reactions may 
present with similar serious clinical manifestations as anaphylaxis, but without prior exposure to 
the drug and are due to nonimmunologic-mediated mast cell degranulation.  Although 
mechanistically different, anaphylactic and anaphylactoid reactions are treated similarly.

Page 123
Common symptoms of hypersensitivity reactions seen with other enzyme replacement therapy 
include urticaria, rash, dyspnea, and less frequently, angioedema. Other symptoms of 
hypersensitivity IARs, APRs, and CRS include fever, hypotension, tachycardia, nausea, vomiting, 
pain, and headache.
There were no IARs suggestive of hypersensitivity in the Phase 1b trial (6).
10.5.1.3.2.2
Acute phase reactions
Acute phase reactions are considered a type of IAR.  Acute phase reactions were observed in the 
Phase 1 single-dose study (5) and the Phase 1b repeat-dose study (6) in 2 patients during dose 
escalation.  The patients successfully completed the trial.  Typically, APRs occurred within 12 to
72 hours after olipudase alfa infusion and were indicative of an inflammatory response as they 
were associated with elevations in hsCRP and changes acute phase reactants including, but not 
limited to, neutrophils, iron, ferritin, fibrinogen, D-dimer, transferrin, albumin, prothrombin time,
and partial thromboplastin time. Typical AEs that were reported by the patient included, but were 
not limited to, pyrexia, nausea, vomiting, fatigue, and pain; and were concurrent with the changes 
in specific laboratory parameters. Accordingly, APRs will be determined based on combined 
significant laboratory findings and clinical symptoms.
10.5.1.3.2.3
Cytokine release syndrome
Cytokine release syndrome is another type of IAR, attributed to the release of excessive amounts 
of cytokines shortly after the IV administration of certain therapeutic agents.  The severe form of 
CRS is cytokine storm, which may be life threatening.  Nonclinical studies of high-dose olipudase 
alfa have suggested the possibility of CRS.  There were no events characterized as cytokine 
release syndrome in either the Phase 1 single- or the Phase 1b repeat-dose trials with olipudase 
alfa (5, 6). The Phase 1 single-dose study demonstrated increases in IL-8 and IL-6; macrophage 
inflammatory protein 1, alpha component (MIP-1α); macrophage inflammatory protein 1, beta 
component (MIP-1β); and other cytokines and biomarkers (based Myriad Rules-Based Medicine 
Human Multi-Analyte Profile® antigen panel) after a single dose of ≥0.3 mg/kg of olipudase alfa 
(5). In the Phase 1b trial, increases in mean IL-6 and IL-8 values were associated with the 
first administrations of olipudase alfa at doses 0.6 mg/kg through 2.0 mg/kg and tended to be 
concurrent with acute phase responses (6). Unlike immunoglobulin-mediated hypersensitivity 
reactions, no prior antigen exposure is required for the development of CRS.  Symptoms of CRS 
develop soon after exposure, and range from mild to severe.  Although CRS shares some 
symptoms with other IARs (ie, hypersensitivity reactions and APRs), symptoms typical of CRS 
include pyrexia, nausea, vomiting, fatigue, pain, myalgia, and in severe cases, multiorgan system 
dysfunction or failure, severe headache, and pulmonary edema.  Cytokine release syndrome will 
be determined based on combined significant laboratory findings and clinical symptoms.
10.5.1.3.3Symptomatic overdose (serious or nonserious) of study drug
An overdose (accidental or intentional) of study drug is defined as an increase of at least 30% of 
the dose to be administered in the specified duration or if the dose is administered in less than half

the recommended duration of administration.  An asymptomatic overdose will be reported as 
a standard AE.
10.5.1.3.4Laboratory values
The following laboratory values and symptoms will be considered AESIs (see also dose stopping 
criteria in Section 8.1.6), as follows:
x
Any increase in AST, ALT, total bilirubin, or AP >3x baseline (prior to olipudase alfa 
therapy) and > ULN.
x
Any increase in total bilirubin or AP >1.5x baseline in the presence of AST or 
ALT > 2x ULN.
x
Any increase in ALT or AST >3x the ULN combined with an increase in ALT or 
AST >2x baseline (prior to olipudase alfa therapy) with symptoms of fatigue, nausea, 
vomiting, right upper quadrant pain or tenderness, fever, rash, or eosinophilia (> ULN).
10.5.1.3.5Other significant events
Any AE that, in the opinion of the investigator or sponsor, raises significant concern regarding the 
safety of olipudase alfa at the administered dose will be considered an AESI.
10.5.1.4 Definitions for criteria of adverse events
10.5.1.4.1Relationship to study treatment
Assessment of the association between the AE and study exposure is important for regulatory 
reporting.  This assessment is to be made in blinded studies and also for known comparators.  For 
each AE/SAE the investigator is to determine whether there is a reasonable possibility 
demonstrated by evidence which suggests a causal relationship between the study treatment and 
the AE according to the categories below:
x
Not related: There is no suspicion of a causal relationship between exposure and the AE.
x
Unlikely related: There is no evidence for a causal relationship between exposure and the 
AE; however, such a relationship cannot be ruled out.
x
Possibly related: There is some evidence supporting the possibility of a causal relationship 
between exposure and the AE.
x
Related: There is strong evidence that there is a causal relationship between exposure and 
the AE.
A relationship to the investigational product must be assigned for each AE/SAE recorded, even if 
there is only limited information at the time. The investigator may change his/her opinion of 
causality in light of follow-up information, amending the AE/SAE report accordingly.

10.5.1.4.3Outcome
Outcome describes the status of the AE.  The investigator will provide information regarding the 
patient outcome of each AE.  Definitions for possible results of an AE include:
x
Fatal: The termination of life as a result of an AE.
x
Not recovered/not resolved: The patient has not recuperated, or the AE has not improved.
x
Recovering/resolving: The patient is recuperating, or the AE is improving.
x
Recovered/Resolved: The patient has recuperated, or the AE has resolved.

Recovered with sequelae/resolved with sequelae: The AE has resolved, but the patient has 
been left with symptoms or pathology.
x
Unknown: Not known, not observed, not recorded, or refused.
10.5.1.4.4Action taken regarding the investigational product
The investigator will be required to provide the action taken regarding investigational product 
(eg, active, comparator) in response to the AE. Options include:
x
Dose increased: Increase in the frequency, strength, or amount of investigational product 
administered.
x
Dose not changed: No change in administration of the investigational product.
x
Dose reduced: Reduction in the frequency, strength, or amount of investigational product 
administered.
x
Drug (investigational product) interrupted: Temporary interruption in administration of the 
investigational product.
x
Drug (investigational product) withdrawn: Administration of the investigational product 
terminated (no further dosing).

10.5.2.1 General guidelines
See Table 30 for an overview of AE reporting instructions.
x
All AEs, regardless of seriousness or relationship to study treatment spanning from the 
signature of the informed consent form until the end of the study are to be recorded on the 
corresponding CRF.
x
Except for IARs, whenever possible, diagnosis or single syndrome will be reported instead 
of symptoms.  For IARs, all symptoms must be separately recorded.
x
The investigator will 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.
x
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.
x
Laboratory, vital sign measurements, or ECG abnormalities 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 (Section 10.5.1.3).
10.5.2.2 Instructions for reporting serious adverse events
In the case of occurrence of an SAE, the investigator must immediately:
x
ENTER (within 24 hours) the information related to the SAE in the appropriate screens of 
the CRF; the system will automatically send a notification to the monitoring team after 
approval of the investigator within the CRF or after a standard delay.  If automatic 
notification is not available, paper SAE notifications must be sent manually to the local 
Pharmacovigilance and Epidemiology office.

x
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 the sponsor.  For laboratory results, include the laboratory normal ranges.
x
All further data updates should be recorded in the 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.
x
A back-up plan (using a paper CRF process) is available and should be used when the 
electronic 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 the monitoring team.
10.5.2.3 Guidelines for reporting adverse events of special interest
10.5.2.3.1Reporting of adverse events of special interest with immediate notification
For AESIs the sponsor will be informed within 24 hours as per the SAE notification instructions 
described in Section 10.5.2.2 even if not fulfilling a seriousness criterion, using the corresponding 
screens in the CRF.
x
Pregnancy
-
Pregnancy occurring in a female patient included in the clinical trial.  Pregnancy will 
be recorded as an AESI with immediate notification in all cases.  It will be qualified as 
an SAE only if it fulfills the SAE criteria,
-
In the event of pregnancy, study drug should be discontinued,
-
Follow-up of the pregnancy is mandatory until the outcome has been determined.
x
Infusion-associated reaction (see Section 10.5.1.3.2), which include:

PREGNANCY REPORTING
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.
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 10.5.2.3.1 to contact the sponsor within 
24 hours.  The investigator will be asked to complete the AE form, the safety complementary 
form, and the pregnancy form.  The patient will be followed until the outcome of the pregnancy is 
known.  The investigator will be responsible for this follow-up.
If not otherwise established, the investigator will inform the patient that the sponsor is required to 
gather information regarding the course and outcome of the pregnancy after exposure to a study 
product.  The progress of the pregnancy must be followed until the outcome of the pregnancy is 
known (ie, delivery, elective termination, or spontaneous abortion).  If the pregnancy results in the 
birth of a child, additional follow-up information may be requested.
The investigator will be asked to obtain follow-up information no later than 2 months after the 
gestational period to obtain maternal/fetal/neonatal outcome and any other relevant information.  
Follow-up information may be requested at additional time points.  All study-related 
visits/contacts involving a known pregnancy should include pregnancy status assessment until 
pregnancy outcome is known.
Please note that pregnancy is an AESI, not an AE or SAE.  All information received will be 
assessed for any AEs and SAEs and processed per study guidelines.  If the patient is discontinued 
because of pregnancy, pregnancy will be documented as the reason for study discontinuation.  
Spontaneous abortions and stillbirths are reported as SAEs.
10.7
OBLIGATIONS OF THE SPONSOR
During the course of the study, the sponsor will report in an expedited manner:
x
All SAEs that are both unexpected and at least reasonably related to the IMP (suspected 
unexpected serious adverse reaction), to the health authorities, independent ethics 
committees (IECs)/institutional review boards (IRBs) as appropriate, and to the 
investigators.
x
All SAEs that are expected and at least reasonably related to the IMPs to the health 
authorities according to local regulations.
The sponsor will report all safety observations made during the conduct of the trial in the clinical 
study report.
10.8
ADVERSE EVENTS MONITORING
All events will be managed and reported in compliance with all applicable regulations and will be 
included in the final clinical study report.

STATISTICAL CONSIDERATIONS
An SAP will be written and finalized prior to database lock to give guidance to the statistical 
analysis.  It will be in compliance with the International Council on Harmonisation (ICH) and 
Food and Drug Administration’s Guidance for Industry: Statistical Principles for Clinical Trials.
11.1
GENERAL CONSIDERATIONS
The sponsor or its designee will perform the statistical analysis of the data from this study.  The 
analysis will be performed using the SAS® statistical software system Version 9.3 or higher.
Important CRF data, as well as any outcomes derived from the data, will be displayed in patient 
data listings.  Categorical variables will be summarized using frequencies and percentages, and 
continuous variables will be summarized using descriptive statistics (number of patients with
observation, mean, standard deviation, median, minimum, and maximum).
11.1.1 Final analysis
The final analysis will be performed at the completion of the treatment period.  This analysis will 
include safety, efficacy, PK, and PD data.  Analyses of change will be based upon changes from 
baseline prior to olipudase alfa therapy (ie, baseline in the previous study [DFI13412 or 
DFI13803]) through study completion.  The final statistical analyses will be performed when the 
entire database is locked and signed off, in accordance with the standard operating procedures of 
the sponsor or designee.
11.2
DETERMINATION OF SAMPLE SIZE
Sample size will be determined by the number of patients who complete the treatment phase of 
a previous clinical study of olipudase alfa, sign the informed consent form for the LTS13632 
study, and meet the eligibility criteria.  It is expected that the sample size for this study will be 
approximately 25.
11.3
DISPOSITION OF PATIENTS
Enrolled patients are defined as patients who signed informed consent forms.
Patient enrollment will be summarized for the enrolled patient set by study site, including 
frequency and percentage of patients who received at least 1 infusion (total or partial) of study 
treatment.
All patients who receive an infusion (total or partial) of olipudase alfa (safety population) will be 
included in the summary of patient disposition.  The number and percentage of patients who either 
complete the study or withdraw from the study, and/or withdraw from treatment, along with the

reasons for their withdrawal, and who completed or discontinued the posttreatment safety 
follow up will be presented.
11.4
ANALYSIS POPULATIONS
The safety set will include all enrolled patients who received at least 1 infusion (partial or total) of 
olipudase alfa in the current study.
The PK analysis includes all patients who receive at least 1 infusion of study drug after PK 
analysis informed consent and have evaluable PK data.  Other analysis populations, such as for 
pharmacogenomics, if any, will be defined in the SAP.
Subgroup analyses may be conducted for safety and efficacy endpoints in subpopulations of the 
safety set.  Subpopulations may be defined by parameters including, but not limited to, age, 
gender, genotype, exposure to study treatment, pre-dose (trough) plasma concentration of 
olipudase alfa, and concomitant therapies.  Further details will be provided in the SAP.
Throughout the study, “baseline” refers to the baseline in the previous study (DFI13412 or 
DFI13803).
11.5
DEMOGRAPHIC AND BASELINE CHARACTERISTICS
Demographic and baseline characteristics will be summarized using descriptive statistics for the 
safety set.
11.6
STATISTICAL METHODS
All analysis will be done on the safety set unless specified otherwise.
11.6.1 Extent of investigational medicinal product exposure
The extent of study treatment exposure will be assessed and summary statistics will be presented.
11.6.2 Analyses of efficacy endpoints
Efficacy assessments are described in Section 9.2.
Summary statistics for the values, nominal change from baseline, and percent change from 
baseline will be presented for efficacy assessments at various study time points.  The baseline 
value is defined to be the latest assessment value prior to the first dose of study treatment in the 
primary study.  For selected parameters, the mean (95% confidence interval) or median 
(interquartile range) may be plotted over time.  Categorical variables will be summarized using 
frequencies and percentages at various study time points.
The association between changes in efficacy parameters and total amount of drug received may be 
examined.

11.6.2.1 Multiplicity considerations
Not applicable.
11.6.3 Analyses of safety data
Safety assessments are described in Section 9.1.4 through Section 9.1.15.  All safety analyses will 
be performed on the safety set (defined in Section 11.4).  No formal inferential testing will be 
performed.  Summaries will be descriptive in nature.
The following definitions will be applied to laboratory parameters, ECGs, and vital sign 
measurements.
x
The potentially clinically significant abnormality (PCSA) values are defined as abnormal 
values considered medically important by the sponsor according to predefined 
criteria/thresholds based on literature review and defined by the sponsor for clinical 
laboratory tests and vital signs.
x
PCSA criteria will determine which patients had at least 1 PCSA during the treatment 
period, taking into account all evaluations performed during the treatment period, 
including unscheduled or repeated evaluations.  The number of all such patients will be the 
numerator for the treatment PCSA percentage.
x
Treatment period: the treatment period used for quantitative analysis is defined as the time 
from first dose to the last dose of IMP +14 Days.
11.6.3.1 Adverse events
The definitions in Section 10.5.1 will be used for AEs.  Pretreatment AEs will be listed and 
presented separately from treatment-emergent AEs.
All AEs will be coded using the most recent version of the MedDRA.  Adverse event incidence 
tables will present by system organ class (SOC) (sorted by internationally agreed order) and 
preferred term (PT) sorted in alphabetical order for each treatment group, and the number 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.
All treatment-emergent AEs, all treatment-emergent AEs potentially related to olipudase alfa, all 
treatment-emergent AEs leading to treatment discontinuation and study discontinuation, all 
treatment-emergent AEs that are IARs, all treatment-emergent SAEs (including treatment-related 
SAEs), and all AEs with fatal outcomes (including fatal treatment-emergent AEs) will be 
summarized.
Detailed listings of AEs, SAEs, AESIs, related AEs, and discontinuations due to AEs will be 
provided.  These will include the olipudase alfa dose of the infusion prior to or during the 
occurrence of the AE, where applicable.

For the overall analyses of AEs, the number of AEs and annualized rate, and the number and 
proportion of patients experiencing specific AEs will be tabulated according to the olipudase alfa 
dose level of the infusion prior to or during the occurrence of the AE.
Separate analyses of AEs will also be conducted by demographic characteristics (eg, age and sex).  
Adverse events of special interest, such as IARs, and SAEs will be analyzed similarly.
11.6.3.1.1Adverse events of special interest
Detailed listings for AESIs, including IAR, APR, and CRS will be provided.
11.6.3.1.2Deaths
The following deaths summary will be generated:

Treatment-emergent AE leading to death (death as an outcome on the AE CRF page as 
reported by the investigator) by primary SOC and PT showing number and percent of 
patients sorted by internationally agreed order of SOC and alphabetic order of PT.
11.6.3.2 Laboratory data and vital sign measurements
11.6.3.2.1Physical examinations, vital sign measurements, electrocardiograms, and 
echocardiograms
Observed values and changes from baseline (as applicable) will be summarized descriptively 
overall and by highest tolerated dose and/or by dose received prior to evaluation.  Outlier 
summaries for the ECG parameters (eg, QTc) will be created for the safety set.
11.6.3.2.2Clinical laboratory tests
Observed values and changes from baseline to study time points will be summarized descriptively 
overall and by highest tolerated dose and/or by dose received prior to evaluation.  All laboratory 
values will be classified as normal, above normal, or below normal based on normal ranges 
provided by the laboratory.  Frequencies of CS abnormal values and shifts from baseline to study 
time points will be summarized.  Patient listings of biomarkers will be provided.
11.6.3.3 Immune response assessments
Immune response assessments will be analyzed in the safety set.  The presence, absence, and titers 
of serum anti-olipudase alfa IgG antibodies will be summarized.  The data will be summarized 
over time overall and by the dose level of the infusion prior to or during the evaluation.
Levels of acute phase reactants, serum tryptase, complement activation, neutralizing antibodies, 
and anti-olipudase alfa antibodies (IgG and IgE) obtained in response to an IAR, and skin testing 
results (if available), will be presented in patient listings, if applicable.

observations and other data pertinent to the clinical investigation in a timely manner.  All CRFs 
should be completed in their entirety in a neat, legible manner to ensure accurate interpretation of 
data.
Should a correction be made, the corrected information will be entered in the CRF overwriting the 
initial information.  An audit trail allows identifying the modification.
Data are available within the system to the sponsor as soon as they are entered in the CRF.
The computerized handling of the data by the sponsor when available in the CRF may generate 
additional requests (discrepancy resolution form) to which the investigator is obliged to respond 
by confirming or modifying the data questioned.  The requests with their responses will be 
managed through the CRF.

APPENDIX A: COUNTRY SPECIFIC REQUIREMENTS
This section is not applicable. 
17.2
APPENDIX B: PROTOCOL AMENDMENT HISTORY
The Protocol Amendment Summary of Changes Table for the current amendment is located 
directly before the Clinical Trial Summary.
17.2.1 Amended Clinical Trial Protocol 06 (29-Jan-2021)
This amended protocol (06) is considered to be substantial based on the criteria set forth in 
Article 10(a) of Directive 2001/20/EC of the European Parliament and the Council of the
European Union.
OVERALL RATIONALE FOR THE AMENDMENT
The primary reasons for this amendment are described below:
1. During a regional or national emergency declared by a governmental agency such as the 
COVID-19 pandemic, to allow more flexibility with regard to additional options for monitoring 
techniques in compliance with applicable country-specific regulations.
2. During a regional or national emergency declared by a governmental agency such as the 
COVID-19 pandemic that can lead to site closure or extenuating circumstances that prevent an in-
person site visit, for the switch from Process C(
) investigational medicinal product (IMP) to the 
updated manufacturing Process C(
) IMP, adding the possibility to perform the first infusion at 
home for eligible patients in agreement between the Sponsor and the Investigator and in 
compliance with applicable country-specific regulations. 
3. Liver function test (LFT) monitoring after infusion is already included in this protocol. 
However, review of the interim data from the clinical development program has identified 
"Transient elevation in transaminases associated with ceramide release during the dose escalation 
phase with olipudase alfa" as an important identified risk. Therefore, additional recommendations 
for the management of transaminase elevation during dose escalation have been added to the 
protocol. 
Other important changes include:
1. In the context of this long-term study, the assessments have been streamlined to reduce patient 
burden. Assessments to ensure patient safety will be preserved. This change will be implemented

submissions in 2021 
Analysis of sphingomyelin, 
ceramide and other metabolites 
(sphingosine-1- phosphate) in 
plasma or DBS through 
52 weeks of treatment has been 
completed for all patients. Lyso-
sphingomyelin and ceramide 
which represent the most 
informative readouts for 
pharmacodynamic response to 
treatment will be maintained 
throughout the study to continue 
to monitor levels of substrate 
and its metabolic product. In the 
context of this long-term study, 
these assessments will be 
streamlined to reduce patient 
burden. Assessments to ensure 
patient safety have been 
preserved. 
Clinical Trial Summary-
Assessment Schedule 
Addition of:  
48 hours post-infusion assessments will no longer be 
assessed after the cutoff date for a planned second database 
lock of the study for purpose of regulatory submissions in 
2021. 
During the dose escalation period, for transaminases 
assessed after infusion, if any AST or ALT value is >2x 
baseline and >ULN, the test should be repeated prior to the 
next scheduled infusion. Depending on the test results, the 
dose can be adjusted (repeated or reduced) or treatment can 
be withheld to allow additional transaminase monitoring, 
based on the physician’s clinical judgment. 
The assessments have been 
streamlined to reduce patient 
burden in the extension phase of 
this trial. 
Assessments to ensure patient 
safety have been preserved. 
The 48 hours post-infusion 
assessments no longer

Description of Change 
Brief Rationale 
Baseline is defined as the following:  
· For initial dose escalation: last values prior to first dose of 
olipudase alfa 
· For dose re-escalation: last values prior to the first re-
escalation dose 
Below text is updated: 
In the first 5 years, pharmacodynamic (PD) evaluations will 
occur every 3 months then every 6 months after the cutoff 
date for a planned second database lock of the study for 
purpose of regulatory submissions in 2021. After 5 years, PD 
evaluations will occur every 12 months. PK evaluation will 
occur every 12 months only in the first 5 years and upon 
introduction of Process C(
) or Process C(
) at any time 
during the study.  
assessments remain. Therefore, 
patient safety is not being 
compromised. 
Transient elevation in 
transaminases associated with 
ceramide release during the 
dose escalation phase with 
olipudase alfa has been added 
as an important identified risk. 
Therefore, additional 
recommendations for the 
management of transaminase 
elevation during dose escalation 
have been added to the 
protocol. 
Section 1 - Study Flow 
Charts.
Updated manufacturing scale has been replaced by Process 
C(
). 
Updated manufacturing process has been replaced by 
Process C(
). 
Five new flowcharts (Tables 2, 4, 6, 8, and 10) have been 
added (resulting in table renumbering) describing 
assessments after cutoff for planned second database lock in 
2021. 
Previous flow charts with the addition of: only applicable 
before the implementation of changes that will occur after the 
cutoff date of the second database lock  
For each of the flow charts initially presented in the protocol, 
complementary flow charts have been added to be effective 
after the cutoff date for a planned second database lock of the 
study for purpose of regulatory submissions in 2021. 
The following parameters will no longer been assessed: 
-
Metabolites in plasma: ACE, sphingomyelin  
-
Metabolites in dried blood spot  
-
48 hours after infusion: vital sign measurements, 
LFTs, hematology, and safety during dose re-
escalation 
Timing changed from quarterly to every 6 months through 
Year 5 for the following parameters: 
-
Metabolites in plasma: ceramide, lyso-
sphingomyelin 
-
Efficacy biomarkers: serum chitotriosidase, CCL18 
-
Bone biomarkers (alkaline phosphatase, 
C-telopeptide) 
if site visits are not possible (eg, during the COVID-19 
pandemic) replaced by: If the site visit is not possible during a 
Clarification on olipudase alfa 
manufacturing process changes 
In the context of this long-term 
study, some assessments will 
be streamlined to reduce patient 
burden. Given current 
knowledge about the study drug, 
assays can be replaced by 
targeted testing. Assessments to 
ensure patient safety will be 
preserved. This change will be 
implemented after the cutoff 
date for a planned second 
database lock of the study for 
purpose of regulatory 
submissions in 2021 (the first 
cutoff date was on 10 December 
2019): sites will be informed of 
the effective date. 
Analysis of sphingomyelin, 
ceramide and other metabolites 
(sphingosine-1- phosphate) in

Description of Change 
Brief Rationale 
During the dose escalation period, for transaminases assessed 
after infusion, if any AST or ALT value is >2x baseline and 
>ULN, the test should be repeated prior to the next scheduled 
infusion. Depending on the test results, the dose can be 
adjusted (repeated or reduced) or treatment can be withheld to 
allow additional transaminase monitoring, based on the 
physician’s clinical judgment. 
Baseline is defined as the following:  
· For initial dose escalation: last values prior to first dose of 
olipudase alfa 
· For dose re-escalation: last values prior to the first re-
escalation dose 
this trial. 
Assessments to ensure patient 
safety have been preserved. 
The 48 hours post-infusion 
assessments no longer assessed 
after the cutoff date for a planned 
second database lock of the 
study for purpose of regulatory 
submissions in 2021; however, 
24 hours post-infusion 
assessments remain. Therefore, 
patient safety is not being 
compromised. 
Transient elevation in 
transaminases associated with 
ceramide release during the dose 
escalation phase with olipudase 
alfa has been added as an 
important identified risk. 
Therefore, additional 
recommendations for the 
management of transaminase 
elevation during dose escalation 
have been added to the protocol. 
Section 9.1.15 – Immune 
response assessments 
Added: If introduction of a drug product from Process C(
) or 
from Process C(

first 6 months after introducing the drug product from Process 
C(
) or Process C(

Section 9.3.8 
Pharmacokinetics 
PK testing will only occur yearly for the first 5 years and upon 
the introduction of Process C(
) or Process C(
) at any time 
during the study.  For Process C(
), if treatment is not 
interrupted, PK sample collection will take place at the patient’s 
last infusion under the current manufacturing scale and at the 
first infusion Process C(

infusions. 
For the switch from Process C(

the patient should  receive the first infusion at the site. 
However, if the site visit is not possible due to site closure or 
extenuating circumstances that prevent an in-person site visit 
(eg, during COVID-19 pandemic), the first infusion of Process 
C(

Description of Change 
Brief Rationale 
11.6.4 Analysis of 
pharmacokinetic and 
pharmacodynamic variables 
Add manufacturing process update option to PK analysis. 
Addition of manufacturing process 
update. 
11.7 Interim Analysis 
A formal summary of data or interim CSR may be 
produced to support regulatory approval(s) and/or other 
application submission requirement(s) was added to this

15 Clinical Trial Protocol 
Amendments 
Addition of required criteria for written approval/favorable 
opinion of any amendment to the clinical trial protocol 
“also by regulatory authorities if substantial” was added to 
this section.  
This change was made to adhere to 
Sanofi policy. 
17 Appendices 
This entire section, including all subsections (17.1, 17.2, 
17.2.1, 17.2.2, and 17.2.3) were added to the amended 
clinical trial protocol.  
This change was made to adhere to 
Sanofi policy. 
17.2.4 Amended protocol 03 based on Protocol Amendment 03 (25 April 2018)
REASON FOR AMENDMENT:
1. Extend the study treatment period from 5 years to 9 years
In section(s): Clinical Trial Summary: Study Design, Duration of Study Period; 1 Study Flow 
charts (1.1 through 1.6 [former protocol amendment 2 sections 1.1 through 1.4]); 4.2 Study 
Rational; 6 Study Design; 6.1.1 Treatment Period; 6.3 Duration of Study Participation
Rationale:
LTS13632 was set to follow patients rolling over from previous adult study (Phase 1b) and 
Pediatric study (Phase 1/2). The objective is to assess long term safety and efficacy for 5 years or 
until marketing approval whichever comes first. So far, there was no marketing approval and no 
other treatment option available in the study countries.
This change aim to extend safety and efficacy follow up of the enrolled patients if they wish, for 
4 more years or until marketing approval whichever comes first. The treatment period will change 
from 5 years to 9 years to allow for better treatment options for patients at the end of treatment. 
It is also included in this change that if marketing approval was not available, extension of follow 
up beyond 9 years would be considered with sponsor’s approval.
Specific schedules of assessment for both adults and children populations in this extension period 
have been proposed.
2. Remove a redundant exclusion criterion
In section(s): Clinical Trail Summary: Study Population, Main Selection Criteria (Exclusion 
Criteria); 7.2.2 Exclusion criteria related to the current knowledge of the compound and condition

LTS13632 - olipudase alfa
Version number: 1
Property of the Sanofi Group - strictly confidential
Page 160
Rationale:
The exclusion criterion number E 06 states that “The patient has an alanine aminotransferase 
(ALT) or aspartate aminotransferase (AST) >250 IU/L or total bilirubin >1.5 mg/dL”.
However, patients enter the study by rolling over from previous studies (adult Phase 1b and 
pediatric Phase 1/2) without any screening assessment before rolling over after end of treatment of 
the previous study. 
Moreover, Liver Functions are strictly followed in previous studies and this extension study via 
Dose Limiting Toxicities (DLTs) and Dose Stopping Criteria which are also reviewed by Data 
Monitoring Committee (DMC). 
Based on the above, EC 06 is redundant and this amendment proposes to remove.
3. Remove the option of another liver biopsy after 5 years treatment in adult 
patients
In section(s): 1.1 Flow Chart for Adults; 9.1.12 Liver biopsy for sphingomyelin in liver tissue 
(only patients who previously participated in the DFI13412 study)
Rationale:
In the current protocol (Protocol Amendment 2) it is indicated that an additional biopsy may take 
place at 5 years in the study, but only if necessary based on analysis of the 3 year biopsy for the 
group of adult patients.
The 3 year biopsy analysis of the adult patients did not show evidence suggestive of a progressive 
worsening of fibrosis to cirrhosis in patients treated with olipudase alfa. Hence it was decided that 
further biopsies after 5 years treatment is not needed.
4. Update the target number of patients to be approximately 25 instead of 17 
In section(s): Clinical Trial Summary: Total Expected Number of Patients; Statistical 
Considerations, sample Size Determination; 6 Study Design; 11.2 Determination of the Sample 
Size
Rationale:
All adult patients were recruited. This change serves to update the target number of patients 
according to Phase 1/2 pediatric (DFI13803) study amendment 4 (dated 21-Aug-2017), which 
plans to enroll approximately 20 patients, instead of 12.
5. Remove selected assessments from the flow chart list 
In section(s): 1.3 (former protocol amendment 2 Section 1.2) Flow Chart for Pediatric (Former 
DFI13803) Patients: Year 1; 1.4 (former protocol amendment 2 Section 1.2) Flow Chart for 
Pediatric (Former DFI13803) Patients: Year 2 Through Year 5; 9.3.3 Cycle ergometry;

Version number: 1
Property of the Sanofi Group - strictly confidential
Page 161
Rationale:
Remove cycle ergometry in pediatric patients. The assessment has not provided any benefit to 
follow activities in children due to the difficult applicability and low compliance.
Remove Angiotensin Converting Enzyme measurement in both adult and pediatric populations. 
The assessment does not provide any benefit to follow efficacy or safety.
6. Add option to conduct a future additional questionnaire about home infusion 
experience to patients who received home infusion treatment 
In section(s): 9.1.2 Secondary endpoints (efficacy); 9.2.6.3 Additional questionnaires; 
10.2.1 Home infusions
Rationale:
This is a provision in the protocol of the option to conduct future additional short and one-time 
questionnaire about home infusion experience to patients who received home infusion treatment.
7. Add Differential liver DNA methylation densities of PPARɣ gene promoter in 
plasma ccfDNA
In section(s): Clinical Trial Summary (End Points), (Other endpoints); 9.1.3 Other endpoints; 
9.3.10 Differential liver DNA methylation densities of PPARɣ gene promoter in plasma
Rationale:
Differential liver DNA methylation of peroxisome proliferator-activated receptor gamma 
(PPARɣ) gene promoter has recently been shown to stratify patients in terms of fibrosis severity. 
Plasma DNA methylation signatures reflect the molecular pathology associated with fibrosis liver 
disease. Remarkably, PPARɣ hypermethylation correlated with progression to cirrhosis in 
alcoholic liver disease (ALD) and with specific stages of liver fibrosis in non-alcoholic fatty liver 
disease (NAFLD). DNA methylation markers at the human PPARɣ promoter detectable in 
circulating cell-free DNA (ccfDNA) display differential methylation densities and could 
potentially be used to non-invasively stratify liver fibrosis severity in patients with NAFLD.
(Hardy T, et al. Gut 2016;0:1-8. doi:10.1136/gutjnl-2016-311526 [downloaded Apr 11, 2016]  and 
Yi.it.B, et.al. Gut Epub ahead of print: doi:10.1136/ gutjnl-2017-315668 [downloaded Feb 26, 
2018])
In order to assess this potential biomarker in ASMD patients, it would be clinically useful to 
compare the differential methylation densities of the adult patients participating in the LTS13632 
study to base differential methylation densities while they were participating in the Phase 1b
(DFI13412) study.
Whenever possible, and if enough volume of left-over plasma is available at all time points of 
interest, plasma samples that were obtained at the same time of the liver biopsy performed at Year 
3 study visit will be used to assess ccfDNA differential methylation densities. These densities will

be compared with the samples taken from the same patients when they were participating in the 
Phase 1b (DFI13412) study, to detect change in fibrosis differentiation using this biomarker. In 
this way, there will be no additional blood draws or procedures added to the protocol.
8. Clarify language of collection of blood samples (beyond 5 years) and 
pharmacokinetics sample and analysis
In section(s): 1.6 (former protocol amendment 2 section 1.4) Study Flowchart: Pharmacokinetic 
sampling; 9.3.8 Pharmacokinetics; 9.3.8.3.1 Sampling time in adults; 9.3.8.4.1 Sampling time in 
pediatric patients; 9.5 Sampled Blood Volume
Rationale:
Clarify and update language to address study extension and clarify other procedures.
9. Clarify reporting guidelines of Adverse Events of Special Interest
In section(s): 10.5.2.5 Summary of adverse event reporting, table 22 (former protocol amendment 
2 table 17)
Rationale:
Adding AESI lab values to the relevant table
17.2.5
Amended protocol 02 based on Protocol Amendment 02 (25 April 2017)
REASON FOR AMENDMENT:
1. Change in assessments that will not be repeated at end of study/early discontinuation 
visit 
In section(s): 1.1, 1.3
Rationale:
Correction of error in previous section.
2. Dose calculation based on weight in site and home infusion visits
In section(s): 1.1, 1.2, 1.3
Rationale:
Weight change between visits is insignificant, therefore dose calculation using weight from 
previous site visit is allowed. In home infusion visit, the last weight taken on site will be used.

17.2.6 Amended protocol 01 based on Protocol Amendment 01 (23 March 2016)
REASON FOR AMENDMENT:
Changes listed in this section are regarded as “substantial” because they have a significant impact 
on:
x
The safety or physical or mental integrity of the patients,
x
The scientific values of the trial; or,
x
The conduct or management of the trial.
1. Change expected number of patients from “65-70 patients” to “up to 17 patients.
In sections: Clinical trial summary (Study population, Total expected number of 
patients), 6.
Rationale: This trial allows current patients to continue treatment.  Based on the number of 
patients in this trial and the DFI13803 pediatric trial, the maximum number of patients is 
already known to be 17.
2. Provide option for home infusions.
In sections: Clinical trial summary (Dose regimen), 8.1.1, 10.2.
Rationale: Patients are on stable doses that they have been tolerating well.  This provision 
eases the travel and hospitalization burden on patients without affecting patient safety.

3. Provide specific guidelines on treatment “reintroduction” defined as management of 
patients who have missed 1 or more olipudase alfa doses.
In sections: Clinical trial summary (Dose regimen), 8.1.1, 8.1.5.
Rationale: Issue was not addressed in previous version.
4. Remove the requirement that the sponsor must be consulted to determine the 
appropriate dose of olipudase alfa for dose adjustments or if a patient misses 1 or 
more doses.
In section: Clinical trial summary (Dose regimen), 8.1.1, 8.1.4.
Rationale: Guidance on how to restart treatment when patients have missed consecutive 
doses is provided in Section 8.1.1 of the protocol.
5. Remove continuous heart rate monitoring as an endpoint.
In sections: Clinical trial summary (Endpoints, Primary endpoints, Data pertaining to the 
safety and tolerability of olipudase alfa), 1.1, 9.1.1, 9.2.
Rationale: Patients in the LTS13632 trial have all completed the dose escalation regimen. 
As such, they are outside the period where fluctuations of ceramide could lead to more 
severe adverse events. The results of continuous ECG monitoring to date from studies 
DFI13412 and LTS13412 have not revealed any clinically significant changes. Moreover, 
enzyme therapies, as a class effect, are not known to detrimentally effect cardiac function. 
As such, continuous ECG monitoring was removed.
6. Add these endpoints.
In sections: Clinical trial summary (Endpoints, Primary endpoints, Data pertaining to the 
safety and tolerability of olipudase alfa), 9.1, 9.2.2.1, 9.2.2.2, 9.2.7, 9.2.8, 9.2.9, 9.3, 9.3.7,

Photographs (optional).
Rationale: These are relevant clinical endpoints for pediatric patients entering the trial, 
which were part of the primary pediatric study, and for continued evaluation of adult 
patients (eg, liver biopsy).
7. Specify that, “The term ‘pediatric patients only’ means patients coming from the 
original pediatric trial, DFI13803.  Some of these patients will reach adult age 
[18 years old] while in this study.  They will continue the assessments schedule they 
were on in the original trial.  These patients will be adults by age, but they will 
remain part of the “pediatric patient” cohort.” They will not follow the adult 
procedures in this study (eg, liver biopsy).
In sections: Clinical trial summary (Assessment schedule), 1.1, 9, 9.4.9.1.
Rationale: Pediatric patients will not have some baseline assessments for comparison 
(eg, liver biopsy, DXA of femurs and spine).  This statement is intended to clarify to site 
personnel which assessments pertain to adults and which to pediatric patients.
8. Add that for patients who missed 3 infusions or more infusions between trials, some 
assessments may be repeated at study entry after discussion between the sponsor and 
the investigator.
In sections: Clinical trial summary (Assessment schedule), 1.1.
Rationale: Since the rate at which sphingomyelin reaccumulates when olipudase alfa is 
interrupted, it may be necessary to repeat some efficacy assessments in case of prolonged 
investigational product suspension.
9. Add: “If a patient has missed 3 or more doses ≥0.6 mg/kg, reintroduction of 
olipudase alfa for patients receiving infusions at home should occur at the 
hospital/study site.  If a patient misses 2 or fewer doses, the investigator can decide 
whether reintroduction for patients receiving infusions at home should occur at the 
hospital/study site.”
In sections: Clinical trial summary (Dose regimen), 1.1, 8.1.1, 8.1.5.
Rationale: To ensure patient’s safety.
10. Add assessments for patients who require dose reintroduction.
x
Patients who require dose reintroduction will have these assessments at each 
infusion until reaching their usual dose of olipudase alfa:
-
Before infusion: vital signs, liver function tests, hematology, ECG, and safety 
biomarkers,
-
Immediately after infusion: vital signs and ECG,
-
24 hours: vital signs, liver function tests, and safety biomarkers,

48 hours: vital signs, liver function tests, hematology, ECG, and safety 
biomarkers.
In sections: Clinical trial summary (Assessment schedule), 1.1, 8.1.5.
Rationale: To monitor patient safety during reintroduction.
11. Add that PK testing will only occur yearly and upon the introduction of a new 
manufacturing scale.
In sections: 1.2, 9.4.8.
Rationale: Provide appropriate and continuous monitoring, in particular for manufacturing 
scale changes.
12. Add that for a new manufacturing scale, if treatment is not interrupted, PK sample 
collection will take place at the patient’s last infusion under the current 
manufacturing scale and at the first infusion under the new manufacturing scale.
In sections: 1.1, 1.2, 9.4.8.
Rationale: To provide patients’ data on drug comparability.
13. Add that if a manufacturing scale change occurs, immune response assessments will 
be monthly for the first 6 months after starting the new scale, and quarterly after 
that.
In sections: 1.1, 1.2, 9.4.8.
Rationale: Per FDA request.
14. Add that in case reintroduction of olipudase alfa coincides with a manufacturing 
scale change, PK samples will be collected at the infusion at which patients receive 
their usual dose of olipudase alfa under the new manufacturing scale. 
In sections: 1.2, 9.3.8.
Rationale: To provide patients’ data on drug comparability.
15. Added PK sampling times, number of samples, and parameters in adults and 
pediatric patients.
In sections: 1.2, 9.3.8.3.
Rationale: Clarify the number of samples for adults and pediatric patients and when they 
will be obtained.
16. Added PK sampling time point at 96 hours for adults and pediatric patients.

Rationale: Allow comparison of PK in adults and pediatric patients.
17. Added PK total blood volumes for pediatric patients.
In sections: 1.2, 9.5.
Rationale: Specify maximum blood volume for blood samples per health authority 
requirement.
18. Add that the patients must be willing and able to avoid certain medications and 
herbal supplements for 10 days before and 3 days after liver biopsies.
In sections: 7.2.1, 8.6.
Rationale: Decrease the risk of bleeding from liver biopsies and to avoid liver toxicity.
19. Clarify patient stopping criteria.
In section: 8.1.7
Rationale: The role of the DMC in an emergency is to review safety data and recommend
stopping the study if necessary to ensure patient safety.  However, this does not limit the 
ability of investigators to make an immediate decision to discontinue dosing in an 
individual patient due to any AE that raises significant concern regarding the safety of 
olipudase alfa, as described in Section 8.1.6 of the protocol.
20. Remove O2 saturation from vital signs.
In section: 9.2.4.
Rationale: As part of this amendment to the protocol, dose escalation is not part of the 
trial.  Patients are on stable doses, and therefore monitoring without measuring 
O2 saturation is appropriate.
21. Change safety biomarker test from multiplex immunoassay to specific biomarkers 
including, but not limited to, hsCRP, iron, ferritin, cardiac troponin I, IL-6, IL-8,
plasma ceramide and calcitonin.
In sections: 9.2.5, 9.2.10.
Rationale: Given current knowledge about the study drug, broad immunoassay can be 
replaced by targeted testing.
22. Change the definition of overdose from “at least twice the intended dose within the 
intended therapeutic interval” to “an increase of at least 30% of the dose to be 
administered in the specified duration, or if the dose is administered in less than half 
the recommended duration of administration.”
In section: 10.5.2.3.1.
Rationale: To align with the investigator brochure and the Sanofi template
