Brief summary:
Evaluating the Efficacy and Safety of Intravenous Ferric Carboxymaltose in Pediatric Patients with Iron Deficiency Anemia and an Unsatisfactory Response to Oral Iron under Study Protocol 1VIT17044

Detailed description:
This is a single arm, open-label, multi-center, multi-national, non-randomized study that will evaluate the efficacy and safety of a one course treatment with FCM in participants who had an unsatisfactory response to oral iron in study 1VIT17044.

Subjects will have an End of Study (EOS) Visit (Day 35) from the 1VIT17044 study to qualify for entry. Subjects will then be screened, meet all inclusion criteria, no exclusion criteria and have a baseline evaluation. Based on the successful completion of the baseline evaluations, subjects will be enrolled and will receive the first dose of FCM (Day 0). The second FCM dose will occur 7 days from the first dose. Subjects will return to the clinic 14 and 28 days post their first dose for laboratory and safety assessments, and at 35 days post the first dose, participants will return to the clinic for final safety and efficacy assessments. Once all assessments are complete the participant will exit the study.

An unsatisfactory response to oral iron (i.e., an increase in hemoglobin (Hgb) of \<1 g/dL from baseline) will be defined as non-responders to oral iron treatment. Non-responders who continue to meet all inclusion criteria (including Hgb \<11 g/dL) and none of the exclusion criteria will receive 1 course of FCM.

Arms:
arm 1: The primary objective in this study is to allow participants who were randomized to receive oral iron in the 1VIT17044 trial and who had an unsatisfactory response to oral iron or those that required a concomitant intervention, (defined as, blood transfusion, use of IV or oral iron outside of protocol, increase in erythropoietin for any reason \[Day 0 thru Day 35 of study protocol 1VIT17044\], change in IBD treatment) to receive one course of FCM. This course of FCM will consist of two doses of FCM at 15 mg/kg (maximum single dose of 750 mg), separated by seven days.

Interventions: intervention 1: Ferric carboxymaltose
Intervention descriptions: intervention 1: IV iron

Title: 
Evaluating the Efficacy and Safety of Intravenous Ferric 
Carboxymaltose in Pediatric Patients with Iron Deficiency 
Anemia and an Unsatisfactory Response to Oral Iron under 
Study Protocol 1VIT17044 
Study Drug: 
Injectafer® (Ferric Carboxymaltose [FCM]) 
Objectives: 
 
The primary objective of this study is to evaluate the 
efficacy and safety of intravenous (IV) ferric 
carboxymaltose (FCM) in pediatric participants who 
have iron deficiency anemia (IDA). 
Nature of Study: 
Phase III 
Design: 
This is a single arm, open-label, multi-center, multi-national, 
non-randomized study that will evaluate the efficacy and 
safety of a one course treatment with FCM in participants 
who had an unsatisfactory response to oral iron in study 
1VIT17044. 
Subjects will have an End of Study (EOS) Visit (Day 35) 
from the 1VIT17044 study to qualify for entry.  Subjects will 
then be screened, meet all inclusion criteria, no exclusion 
criteria and have a baseline evaluation.  Based on the 
successful completion of the baseline evaluations, subjects 
will be enrolled and will receive the first dose of FCM (Day 
0). The second FCM dose will occur 7 days from the first 
dose.  Subjects will return to the clinic 14 and 28 days post 
their first dose for laboratory and safety assessments, and at 
35 days post the first dose, participants will return to the 
clinic for final safety and efficacy assessments.  Once all 
assessments are complete the participant will exit the study. 
An unsatisfactory response to oral iron (i.e., an increase in 
hemoglobin (Hgb) of <1 g/dL from baseline) will be defined 
as non-responders to oral iron treatment.  Non-responders 
who continue to meet all inclusion criteria (including Hgb 
<11 g/dL) and none of the exclusion criteria will receive 1 
course of FCM.  
Inclusion Criteria: 
1. Unsatisfactory response to oral iron or those that required 
a concomitant intervention, (defined as, blood 
transfusion, use of IV or oral iron outside of protocol, 
increase in erythropoietin for any reason [Day 0 thru Day

35 of study protocol 1VIT17044], change in 
Inflammatory Bowel Disease [IBD] treatment). 
2. Hgb <11 g/dL 
3. Ferritin ≤300 ng/mL and Transferrin Saturation (TSAT) 
<30% 
Exclusion Criteria: 
1. Known history of hypersensitivity reaction to any 
component of FCM. 
2. History of acquired iron overload, hemochromatosis, or 
other iron accumulation disorders. 
3. History of significant diseases of the liver, hematopoietic 
system, cardiovascular system, psychiatric disorder, or 
other conditions which, in the opinion of the investigator, 
may place a subject at added risk for participation in the 
study. 
4. Any existing non-viral infection.  
5. Known history of positive hepatitis B surface antigen 
(HBsAg) or hepatitis C viral antibody (HCV) with 
evidence of active hepatitis. 
6. Known history of positive human immunodeficiency 
virus (HIV-1/HIV-2) antibodies (anti-HIV). 
7. Anemia due to reasons other than iron deficiency (e.g., 
hemoglobinopathy and vitamin B12 or folic acid 
deficiency) that has not been corrected.  
8. Administration and / or use of an investigational product 
(drug or device) within 30 days of screening. 
9. Alcohol or drug abuse within the past six months. 
10. Female participant who is pregnant or lactating, or 
sexually active females who are of childbearing potential 
not willing to use an acceptable form of contraceptive 
precautions during the study. 
11. Unable to comply with study procedures and assessments. 
Study Drug 
Administration 
Participants will receive 2 doses (Day 0 and Day 7) of FCM 
at 15 mg/kg to a maximum single dose of 750 mg (whichever 
is smaller) up to a maximum total dose of 1500 mg. FCM will 
be administered as either an undiluted IV push at a rate of 100 
mg (2 mL)/minute OR in no more than 250 mL of normal 
saline and infused over 15 minutes 
Endpoints: 
Primary Endpoint: 
 
Change in Hgb from baseline to Day 35 
 
Secondary Endpoints: 
 
Change in ferritin from baseline to Day 35 
 
Change in TSAT from baseline to Day 35

INTRODUCTION 
1.1. 
Treatment of Iron Deficiency Anemia 
Iron deficiency anemia (IDA) remains the most common nutritional deficiency in 
children in the United States (US) [Looker, 1997]. Rapid growth, insufficient dietary 
intake, and limited absorption of dietary iron combine to place children at increased risk 
for iron deficiency. Iron malabsorption, gastrointestinal blood loss, or iatrogenesis due to 
repeated blood sampling all represent common clinical mechanisms that can result in 
IDA.  Even when recognized, some children are unable to tolerate prescribed oral iron 
supplementation or are unresponsive to it [Kulnigg, 2006]. Anemia may also decrease 
survival rates in adults and children with chronic renal impairment where it is a 
commonly encountered problem [Foley, 1996; Staples, 2010]. In addition, under-
recognized or inadequately treated anemia is likely the most common extra-intestinal 
manifestation of IBD in children, and it can result in a decrease in quality of life and 
increased morbidity, inclusive of hospitalization, in affected patients [Kulnigg, 2006]. 
Non-hematologic consequences of iron deficiency in children include poor weight gain, 
anorexia, irritability, decreased attention span, exercise intolerance, and decreased 
physical activity [Wharton, 1999]. Existing data suggests that chronic IDA in infants and 
toddlers is associated with long-term diminished mental, motor, and behavioral 
functioning.  Although the exact relationship between iron deficiency and its detrimental 
effects on growth and development is not well-understood, it appears that these effects do 
not occur until iron deficiency becomes severe and chronic enough to produce anemia 
[Kazal, 2002]. 
Options for correcting iron deficiency include both oral and parenteral formulations. As 
previously described, some children are unable to tolerate or are non-responsive to oral 
iron.  Blood transfusion is an option to treat anemia and replete iron stores, but often 
scarce supply, as well as the potential risk of blood-borne pathogens, limits its use to 
severely ill or clinically unstable patients [Kulnigg, 2006]. In view of the limitations 
associated with oral iron administration or blood transfusions, IV iron administration is 
an important therapeutic option for use in patients with IDA [Powers, 2014]. 
Multiple parenteral iron products are available. These products vary in the way that iron 
is complexed, which influences the total amount of iron that may be administered during 
a single administration. Numerous other differences differentiate the products.  However, 
all appear to effectively release iron post administration and can restore iron deficit in the 
patient. Previous studies with parenteral iron sucrose (Venofer®) have been performed in 
the pediatric population [Michaud, 2002; Pinsk, 2008; Surico, 2002]. Iron doses have 
varied in these studies, and the data demonstrates the efficacy and safety of Venofer® in 
doses up to 7 mg iron/kg (or 200 mg) administered over 3 minutes, which was shown to 
be beneficial to both the child and health care facility [Michaud, 2002]. 
Ferric Carboxymaltose has been characterized as an iron complex (Type 1) with a 
molecular mass of about 150,000 Daltons. The solution is a dark brown color with a near

Page 14 of 40 
neutral pH (5.0 to 7.0) and a physiological osmolarity permitting administration of higher 
single doses in short time periods. Although no randomized interventional studies have 
been completed with FCM in the pediatric population to date, the product has been used 
successfully to address iron deficiency in pediatric patients with ulcerative colitis and 
Crohn’s disease. A non-interventional, retrospective observational data collection 
reported FCM exposure in 79 patients aged 2 to 18 years with a mean age of 12.7 years.  
In these patients, FCM was found to be safe, well-tolerated, and effective in increasing 
Hgb, ferritin, and TSAT [Favreau, 2017]. 
The proposed study will provide safety and efficacy data on the use of FCM in pediatric 
patients (aged between 1 and 18 years) with IDA. FCM will be administered in 2 doses at 
15 mg/kg maximum single dose of 750 mg with a total maximum cumulative dose of 
1500 mg.  The ability to infuse higher doses of elemental iron should permit repletion in 
fewer overall infusions, and in doing so may ultimately permit fewer visits to the treating 
facilities. 
1.2. 
Ferric Carboxymaltose 
1.2.1. 
Key features of Ferric Carboxymaltose 
Ferric Carboxymaltose injection is a stable, non-dextran, Type I polynuclear 
iron (III)-hydroxide carbohydrate complex developed as an IV iron replacement therapy 
for the treatment of IDA. After IV administration, FCM is mainly found in the liver, 
spleen, and bone marrow.  The iron slowly dissociates from the complex and can be 
efficiently used in the bone marrow for Hgb synthesis.  The carbohydrate moiety of FCM 
is metabolized by the glycolytic pathway.   
1.2.2. 
Ferric Carboxymaltose versus Other Parenteral Iron Agents 
There is considerable efficacy and safety data in the literature with respect to existing 
parenteral iron formulations [Staples, 2010]. However, prior to the approval of non-
dextran formulations, the risk of systemic adverse reactions restricted their use. FCM 
offers significant advantages compared to other available IV iron preparations.  
Iron dextran, the first parenteral iron product available in the US, has been associated 
with an incidence of anaphylaxis/anaphylactoid reactions (i.e., dyspnea, wheezing, 
hypotension, urticaria, angioedema) as high as 1.7% [Michaud, 2002].  Over the last 
20 years, 30 deaths have been attributed to the use of IV iron dextran [Fishbane, 2003].  
The high incidence of anaphylaxis/anaphylactoid reactions is believed to be caused by the 
formation of antibodies to the dextran moiety.  Although some have suggested that high 
molecular weight iron dextran is associated with a higher rate of life threatening adverse 
events and anaphylactic reactions in comparison to low molecular weight iron dextran, 
the US Food and Drug Administration (FDA) was unable to find a clear difference after 
an examination of post-marketing data, clinical trial data, death certificates, and 
emergency room diagnoses [Pinsk, 2008].  Iron dextran is limited to second line therapy 
for treatment of iron deficiency.

More recently approved IV iron formulations, including iron sucrose and iron gluconate, 
do not contain the dextran moiety.  However, they too have significant dosage and 
administration rate limitations.  If the body’s ability to sequester, store, and transport 
infused iron is overwhelmed, a reaction to excess free iron in circulation, referred to as a 
bioactive iron reaction, may occur.  Iron sucrose and iron gluconate preparations carry a 
significant risk of inducing a bioactive iron reaction when delivered at higher doses. 
These reactions are characterized by hypotension (without allergic signs) accompanied by 
pain in the chest, abdomen, flank and/or nausea, vomiting, and diarrhea [Van Wyck, 
2004].  
Due to its structure, FCM is more stable than iron gluconate and iron sucrose, and this 
results in a slower delivery of the complexed iron to endogenous iron binding sites.  
These characteristics of FCM make it possible to administer much higher single doses 
over shorter periods of time than iron gluconate or iron sucrose, resulting in the need for 
fewer administrations to replete iron stores.   
2. 
TRIAL OBJECTIVE 
2.1. 
Primary Objective 
The primary objective of this study is to evaluate the efficacy and safety of IV FCM in 
pediatric participants who have IDA. 
3. 
OVERALL STUDY DESIGN AND RATIONALE 
3.1. 
Overall Study Design  
This is a single arm, open-label, multi-center, multi-national, non-randomized study that 
will evaluate the efficacy and safety of a one course treatment with FCM in participants 
who had an unsatisfactory response to oral iron in study 1VIT17044. 
Subjects will have an EOS Visit (Day 35) from the 1VIT17044 study to qualify for entry.  
Subjects will then be screened, meet all inclusion criteria, no exclusion criteria and have a 
baseline evaluation.  Based on the successful completion of the baseline evaluations, 
subjects will be enrolled and will receive the first dose of FCM (Day 0). The second 
FCM dose should occur 7 days from the first dose.  Subjects will return to the clinic 14 
and 28 days post their first dose for laboratory and safety assessments, and at 35 days 
post the first dose, participants will return to the clinic for final safety and efficacy 
assessments.  Once all assessments are complete the participant will exit the study. 
An unsatisfactory response to oral iron (i.e., an increase in Hgb of <1 g/dL from 
baseline) will be defined as non-responders to oral iron treatment.  Non-responders who 
continue to meet all inclusion criteria (including Hgb <11 g/dL) and none of the 
exclusion criteria will receive 1 course of FCM.

3.2. 
Rationale of Study Design 
The primary objective in this study is to allow participants who were randomized to 
receive oral iron in the 1VIT17044 trial and who had an unsatisfactory response to oral 
iron or those that required a concomitant intervention, (defined as, blood transfusion, use 
of IV or oral iron outside of protocol, increase in erythropoietin for any reason [Day 0 
thru Day 35 of study protocol 1VIT17044], change in IBD treatment) to receive one 
course of FCM.  This course of FCM will consist of two doses of FCM at 15 mg/kg 
(maximum single dose of 750 mg), separated by seven days. 
This study is a rollover for study 1VIT17044 which is an open label, multi-center, multi-
national, randomized, active-control parallel group study that will evaluate the efficacy 
and safety of FCM in pediatric participants, ages 1 to 18 years with iron deficiency 
anemia.

5. 
STUDY DRUG  
5.1. 
Formulation, Packaging and Storage 
The investigational medication to be used in this study [supplied by American Regent, 
Inc.] will have been prepared according to Good Manufacturing Practices (GMP). 
FCM (trade name, Injectafer®) will be supplied as 15 mL vials, containing 750 mg of iron 
as 5% w/v iron containing a polynuclear iron(III)-hydroxide 4(R)–(poly-(14)-O  -D-
glucopyranosyl)-oxy-2 (R), 3(S), 5(R), 6-tetrahydroxy-hexonate complex in a solution of 
water for injection [50 mg/mL] and will be labeled according to FDA investigational 
regulatory requirements.   
FCM must be kept in a secure place at the investigational site, and stored at room 
temperature (see United States Pharmacopeia).  The study medication should not be 
frozen.  Vials of FCM may not be used for more than 1 dose, or for more than 1 
participant.  All FCM vials and syringes (used and unused) should be kept by the study 
staff for reconciliation by the monitor. Following reconciliation, sites may destroy used 
and unused study drug on site using local procedures, provided a drug destruction policy 
is in place, or it may be returned to American Regent, Inc.  
5.2. 
Drug Administration/Regimen  
The Principal Investigator or designee will supervise administration of the study drug to 
participants. All subjects will be dosed with FCM based on the Hgb, TSAT and ferritin 
values from the last scheduled visit in the 1VIT17044 study.  
Participants will receive a dose of FCM at 15 mg/kg to a maximum single dose of 750 
mg (whichever is smaller) on Days 0 and 7 for a maximum total dose of 1500 mg. FCM

will be administered as either an undiluted IV push at a rate of 100 mgs (2 mL)/minute 
OR in no more than 250 mL of normal saline and infused over 15 minutes. 
5.3. 
IV Medication Precautions 
When administering FCM, the following precautions will be taken: 
 
The participant will be evaluated clinically prior to drug administration to assess the 
development of clinically-significant conditions.   
 
The vials will be visually inspected for particulate matter and discoloration before 
use.  If noted, the vial will not be used, and the Investigator or his designee will 
notify the sponsor or sponsor’s designee for replacement of the study drug, and for 
direction on the return of the unused vial. 
 
Heart rate and blood pressure will be assessed pre-, immediately post (within 5 
minutes), and 30 minutes post administration.  Participants will be discharged from 
the site by the Investigator or his or her designee only if there are no significant signs 
or symptoms 30 minutes after the administration is completed. 
 
The participant will be monitored for at least 30 minutes for serious acute reactions 
as hypersensitivity or bioactive (labile) iron reactions to non-dextran IV iron 
products have rarely been reported. The reactions include: hypotension, loss of 
consciousness, bronchospasm with dyspnea, shortness of breath, and seizures. 
 
In the event a serious acute reaction is seen, the site must have the capability to 
provide appropriate resuscitation measures. These may include IV normal 
saline, IV epinephrine, steroids, and/or antihistamines. 
5.4. 
Drug Accountability 
Investigators will keep records of the receipt, administration and return of the study drug 
(FCM).  They will not allow the study drug to be used for purposes other than as directed 
by this protocol.  The investigator agrees that he/she will not supply study medication to 
any persons other than those enrolled in the study, or to investigators not listed on the 
FDA 1572. When the study is completed, or if it is prematurely terminated, a final 
inventory of all clinical supplies must be compiled and the remainder of the unused study 
drug will be returned to American Regent, Inc., or destroyed on site, per the site’s 
documented locally accepted policies. All data regarding the study drug must be recorded 
as per the Monitoring Plan.   
5.5. 
Concomitant Medication 
All concomitant medications will be recorded in the eCRF from 30 days prior to consent.

STUDY PROCEDURES 
6.1. 
Informed Consent 
Prior to any study specific procedures, the investigator must explain to each participant 
the nature of the study, its purpose, procedures to be performed, expected duration, and 
the benefits and risks of study participation.  After this explanation, the participant (who 
for this trial is 1 -18 years old) must assent, if appropriate, and his/her legal guardian 
(who is above age of legal consent) voluntarily sign an informed consent statement 
(Required Elements of Informed Consent, 21 CFR 50.25).  The Code of Federal 
Regulations (CFR) is a codification of rules and regulations of the US government. 
Subjects who are too young to sign an informed consent form, but mature enough to 
understand the study, will provide informed assent per local law.  The subject must be 
able to understand that he or she can withdraw from the trial at any time and for any 
reason. The participant’s legal guardian will be given a copy of the signed consent form.

ASSESSMENT OF SAFETY 
7.1. 
Adverse Events 
Any untoward medical event experienced by a participant during the course of this 
clinical trial, whether or not it is related to the investigational product, at any dose, is 
considered an adverse event (AE).  
For any laboratory abnormality, the investigator will make a judgment as to its clinical 
significance. If the laboratory value is outside the normal limits and is felt to represent a 
clinically significant worsening from the baseline value, it should be considered an 
adverse event and should be recorded on the Adverse Events page of the electronic case 
report form (eCRF). If the laboratory value is outside the normal range, but not an 
adverse event, the investigator should comment on the findings (i.e., “not clinically 
significant” or “unchanged from baseline”) in the source documentation [laboratory

report]. All laboratory values at the EOS/Day 35 that have been deemed clinical 
significant by the Investigator should be followed until they are back into normal range. 
To quantify the severity of adverse events, the National Cancer Institute (NCI)-Common 
Terminology Criteria for Adverse Events (CTCAE), Version 5 or higher should be used 
to grade all events.  These criteria are provided in the procedure manual.   
If a NCI-CTCAE criterion does not exist, the investigator should use Table 2 to assign 
the adverse event grade. 
Table 2 
Grading of Adverse Event Severity 
Grade 
Adjective 
Description 
1 
Mild 
Asymptomatic or mild symptoms; clinical or diagnostic 
observations only; intervention not indicated. 
2 
Moderate 
Moderate; minimal, local or noninvasive intervention 
indicated; limiting age-appropriate instrumental activities 
of daily living (i.e., preparing meals, shopping for 
groceries or clothes, using the telephone, managing 
money, etc.)  
3 
Severe 
Severe or medically significant but not immediately life-
threatening; hospitalization or prolongation of 
hospitalization indicated; disabling; limiting self-care 
activities of daily living (i.e., bathing, dressing and 
undressing, feeding self, using the toilet, taking 
medications, and not bedridden.)  
4 
Life-threatening 
Life-threatening consequences; urgent intervention 
indicated. 
5 
Death 
Results in death due to the AE 
 
Timing: Non-serious AE will be reported from the initial treatment with FCM through 
the completion of the study Day 35. Adverse events will be captured 28 days post the last 
dose of study drug for participants who receive study drug and terminate early from the 
trial. This can be completed via a phone call. All ongoing AE’s related to FCM should be 
followed until they are no longer related, have taken a confounding medication or return 
to baseline grade. 
Relationship (Causality): The Investigator will be asked to document his/her opinion of 
the relationship of the event to the study drug* as follows: 
 NONE 
There is no evidence of any causal relationship 
 UNLIKELY 
There is little evidence to suggest there is a causal 
relationship. There is another reasonable explanation for the

Administrative Change 1 Date: Final 03 December 2019 
Page 26 of 40 
event (e.g., the participant’s clinical condition, other 
concomitant treatments). 
 POSSIBLE 
There is some evidence to suggest a causal relationship (i.e. 
there is a reasonable possibility that the adverse experience 
may have been caused by the agent). However, the influence 
of other factors may have contributed to the event (e.g., the 
participant’s clinical condition, other concomitant events). 
 PROBABLE 
There is evidence to suggest a causal relationship, and the 
influence of other factors is unlikely 
*For the purpose of this trial, study drug is defined as FCM. 
7.2. 
Reporting of Adverse Events 
Adverse experiences will be elicited by nonspecific questions such as “Have you noticed 
any problems?”  Participants will be encouraged to report adverse events at their onset.   
Any adverse experience spontaneously reported by, elicited from the participant, or 
observed by the physician or study staff, shall be recorded on the appropriate Adverse 
Event page of the eCRF. The investigator will record the date and time of onset, severity, 
the relationship to study medication, the date and time of resolution (or the fact that the 
event is still continuing), the action taken, and the outcome of the adverse experience on 
the Adverse Event page of the eCRF. Whenever possible, the investigator should group 
together, into a single term, signs and symptoms which constitute a single diagnosis. For 
example, cough, rhinitis and sneezing might be grouped together as "upper respiratory 
infection."  
7.3. 
Serious Adverse Events 
Definition: An adverse event is classified as SERIOUS if it meets any one of the 
following criteria:  
 
Death 
 
Life-Threatening: The participant was at substantial risk of dying at the time of the 
adverse event or it is suspected that the use or continued use of the product would 
result in the participant's death. 
 
Hospitalization (initial or prolonged): Required admission to the hospital or 
prolongation of a hospital stay. 
 
Disability: Resulted in a significant, persistent, or permanent change, impairment, 
damage or disruption in the participant’s body function/structure, physical activities 
or quality of life. 
 
Congenital Anomaly/Birth Defect. 


CONFIDENTIAL 
American Regent, Inc. 
 
Protocol No.: 1VIT18045 
 
Administrative Change 1 Date: Final 03 December 2019 
Page 27 of 40 
 
Important medical events: Other medically important events that, in the opinion of 
the investigator, may jeopardize the participant or may require intervention to 
prevent one of the other outcomes listed above. 
A distinction should be drawn between SAE and severe AE.  A SAE is a major 
experience of its type.  A SAE is not necessarily serious: e.g. nausea, which persists for 
several hours, may be considered severe nausea, but it is not an SAE.  On the other hand 
a stroke, which results in only a limited degree of disability may be considered a mild 
stroke, but would be a SAE. 
Timing: All SAEs will be reported from the day of initial treatment with *study drug 
through the completion of the study Day 35.  Serious adverse events will be captured 28 
days post the last dose of study drug for participants who terminate early from the trial. 
This can be completed via a phone call. Hospitalization resulting from a historical 
condition (present prior to initial treatment with study drug or prescheduled prior to 
treatment with study drug) that has not increased in severity or led to prolongation of 
hospital stay should not be considered a SAE. All reported SAE should be followed until 
they are no longer serious or return to baseline grade.   
Reporting: Any SAE, starting with the first dose of study drug, that is to be reported (as 
outlined in Timing section above) must be reported immediately (within 24 hours of 
learning of the event) to American Regent, Inc. by telephone, email and/or fax of the 
written SAE report form to the contacts listed below: 
Safety Monitor 
American Regent, Inc. 
Phone: (800) 734-9236 
Fax: (610) 650-0170 
Email: pv@americanregent.com 
The local investigator is responsible for reporting SAEs to their local Institutional Review 
Board (IRB)/ Ethics Committee based on local reporting guidelines (which may be 
different than those specified in this protocol). The responsible investigator should 
institute appropriate diagnostic and therapeutic measures and keep the participant under 
observation for as long as is medically indicated.

STATISTICS 
Continuous variables will be summarized in terms of the number of observations, mean, 
standard deviation (SD), median, Q1, Q3, minimum and maximum. Other descriptive 
statistics (e.g., coefficient of variation) may be reported when appropriate. Categorical 
variables will be summarized using frequency counts and percentages.   
Generally, data will be summarized by nominal visit.  However, data from both 
unscheduled and scheduled will be used for determination of last observed value, and in 
worst- or best-case changes and/or shifts from baseline. Assessment windows will not be

defined for the purpose of classifying measurements obtained outside scheduled 
assessment times. 
A complete description of the statistical analyses and methods will be available in a 
Statistical Analysis Plan (SAP), which will be finalized before the database is locked. 
8.1. 
Stratification/Randomization 
This is a non-randomized, single arm study. 
8.2. 
Analysis Populations 
Safety Population 
The safety population will consist of all participants who received at least one dose of 
study drug.   
8.3. 
Disposition and Baseline Characteristics 
The number of participants in each investigative site will be summarized.  The number of 
participants who are screened, treated, prematurely discontinue, and complete the study 
will be summarized.    
The clinical team will identify deviations and the deviations will be identified in the 
database.  Participants with clinically important protocol deviations will be summarized. 
Demographics and baseline characteristics will be summarized using descriptive statistics 
or frequency counts. 
8.4. 
Endpoints and Definitions 
8.4.1. 
Primary Endpoint 
The primary endpoint is the change in Hgb from baseline to day 35.  Descriptive statistics 
will be provided for the baseline Hgb, the day 35 Hgb, and the within-participant change 
from baseline.  The change in Hgb from baseline to day 35 will be analyzed using paired 
t-tests. 
8.4.2. 
Secondary Endpoints 
Secondary efficacy endpoints include: 
 
Change in ferritin from baseline to Day 35 
 
Change in TSAT from baseline to Day 35  
 
Changes from baseline in Hgb, ferritin, TSAT, and CHr throughout the study 
Details of analyses for these endpoints will be outlined in the SAP.

8.4.3. 
Missing Data 
A participant who withdraws from the study for any reason will be included in the 
analyses regardless of time on study. Methods for handling withdrawals and missing data 
will be specific to each endpoint to be analyzed. Missing data will not be imputed for 
descriptive statistical summaries in safety or efficacy. Details will be provided in the 
SAP. 
8.5. 
Analyses of Safety 
8.5.1. 
Study Drug Exposure 
The number of infusions and total administered amount of iron will be summarized 
descriptively.  
8.5.2. 
Adverse Events 
Adverse events will be coded by system organ class (SOC) and preferred term (PT) using 
the Medical Dictionary for Regulatory Activities (MedDRA) dictionary. 
The number and percent of participants who report treatment emergent AE (TEAE) will 
be summarized. A TEAE is an event with onset date on or after the study drug start date.  
Adverse event summaries will exclude preferred terms that describe asymptomatic serum 
ferritin, TSAT, and reticulocyte values (or changes). This approach is justified by the 
reporting of these values in efficacy summaries and is consistent with the protocol-
defined reporting standards for Hgb/hematocrit (Hct) and low iron indices.  For the 
purposes of this study, non-serious anemia (Hgb or Hct below the normal range or 
worsened from baseline) or iron deficiency (iron indices below the normal range or 
worsened from baseline) will not be considered adverse events.  Anemia or iron 
deficiency will be considered end points if an intervention is required. 
The adverse event profile will be characterized with severity (as graded by the NCI-
CTCAE) and relationship (unrelated and related) to study drug. Related adverse events 
will be events that are possibly or probably related to treatment in the investigator’s 
judgment.  
Participants who report the same preferred term on multiple occasions will be counted 
once for the preferred term: under the highest severity when summarized by severity and 
under the closest relationship to study drug when summarized by relationship. If a 
participant reports multiple preferred terms for a SOC, the subject will be counted only 
once for that SOC.   
The number and percent of participants who report treatment-emergent serious adverse 
events will be similarly summarized for each treatment group. The number and percent of 
participants who report treatment-emergent adverse events resulting in discontinuation of 
study drug will be similarly summarized for each treatment group.

Page 30 of 40 
8.5.3. 
Adverse Events of Special Interest 
Adverse events (AEs) of special interest include hypersensitivity, hypersensitivity-like 
reactions, and cardiovascular events. Hypersensitivity and hypersensitivity-like reactions 
will be identified using standardized MedDRA queries. Cardiovascular events will be 
identified using the SOCs for cardiac disorders and vascular disorders. 
The overviews and summaries that are provided for all TEAEs will also be provided for 
the AEs of special interest. In addition, the time to onset and time to recovery will be 
summarized. 
8.5.4. 
Clinical Laboratory Findings 
Clinical laboratory variables will be presented in two ways.  First, the mean change from 
baseline to each scheduled visit will be summarized. Second, the number and percent of 
participants with treatment-emergent potentially clinically significant (PCS) laboratory 
values will be tabulated. Treatment-emergent PCS laboratory tests are those in which the 
baseline value is normal and post-baseline value is abnormal (i.e., meets Grade III or 
Grade IV toxicity criteria from the NCI-CTCAE Version 5 or higher).  Baseline will be 
defined as the last value obtained before receiving study drug. 
No formal statistical tests will be performed.   
8.5.5. 
Vital Signs 
The change in vital signs (sitting heart rate and blood pressure) from pre-infusion to each 
post-infusion time point will be summarized descriptively on each dosing day. 
8.5.6. 
Sample Size Rationale 
There were no sample size estimations for this study.  The current study is a rollover for 
study 1VIT17044. There will be a maximum of approximately 36 participants from study 
1VIT17044 who had an unsatisfactory response to oral iron or required an intervention.

Study Synopsis 
Protocol No. 1VIT18045 
Title: 
Evaluating the Efficacy and Safety of Intravenous Ferric 
Carboxymaltose in Pediatric Patients with Iron Deficiency 
Anemia and an Unsatisfactory Response to Oral Iron under 
Study Protocol 1VIT17044 
Study Drug: 
Injectafer® (Ferric Carboxymaltose [FCM]) 
Objectives: 
 
The primary objective of this study is to evaluate the 
efficacy and safety of intravenous (IV) ferric 
carboxymaltose (FCM) in pediatric participants who 
have iron deficiency anemia (IDA). 
Nature of Study: 
Phase III 
Design: 
This is a single arm, open-label, multi-center, multi-national, 
non-randomized study that will evaluate the efficacy and 
safety of a one course treatment with FCM in participants 
who had an unsatisfactory response to oral iron in study 
1VIT17044. 
Subjects will have an End of Study (EOS) Visit (Day 35) 
from the 1VIT17044 study to qualify for entry.  Subjects will 
then be screened, meet all inclusion criteria, no exclusion 
criteria and have a baseline evaluation.  Based on the 
successful completion of the baseline evaluations, subjects 
will be enrolled and will receive the first dose of FCM (Day 
0). The second FCM dose will occur 7 days from the first 
dose.  Subjects will return to the clinic 14 and 28 days post 
their first dose for laboratory and safety assessments, and at 
35 days post the first dose, participants will return to the 
clinic for final safety and efficacy assessments.  Once all 
assessments are complete the participant will exit the study. 
An unsatisfactory response to oral iron (i.e., an increase in 
hemoglobin (Hgb) of <1 g/dL from baseline) will be defined 
as non-responders to oral iron treatment.  Non-responders 
who continue to meet all inclusion criteria (including Hgb 
<11 g/dL) and none of the exclusion criteria will receive 1 
course of FCM.  
Inclusion Criteria: 
1. Unsatisfactory response to oral iron or those that required 
a concomitant intervention, (defined as, blood 
transfusion, use of IV or oral iron outside of protocol, 
increase in erythropoietin for any reason [Day 0 thru Day

INTRODUCTION 
1.1. 
Treatment of Iron Deficiency Anemia 
Iron deficiency anemia (IDA) remains the most common nutritional deficiency in 
children in the United States (US) [Looker, 1997]. Rapid growth, insufficient dietary 
intake, and limited absorption of dietary iron combine to place children at increased risk 
for iron deficiency. Iron malabsorption, gastrointestinal blood loss, or iatrogenesis due to 
repeated blood sampling all represent common clinical mechanisms that can result in 
IDA.  Even when recognized, some children are unable to tolerate prescribed oral iron 
supplementation or are unresponsive to it [Kulnigg, 2006]. Anemia may also decrease 
survival rates in adults and children with chronic renal impairment where it is a 
commonly encountered problem [Foley, 1996; Staples, 2010]. In addition, under-
recognized or inadequately treated anemia is likely the most common extra-intestinal 
manifestation of IBD in children, and it can result in a decrease in quality of life and 
increased morbidity, inclusive of hospitalization, in affected patients [Kulnigg, 2006]. 
Non-hematologic consequences of iron deficiency in children include poor weight gain, 
anorexia, irritability, decreased attention span, exercise intolerance, and decreased 
physical activity [Wharton, 1999]. Existing data suggests that chronic IDA in infants and 
toddlers is associated with long-term diminished mental, motor, and behavioral 
functioning.  Although the exact relationship between iron deficiency and its detrimental 
effects on growth and development is not well-understood, it appears that these effects do 
not occur until iron deficiency becomes severe and chronic enough to produce anemia 
[Kazal, 2002]. 
Options for correcting iron deficiency include both oral and parenteral formulations. As 
previously described, some children are unable to tolerate or are non-responsive to oral 
iron.  Blood transfusion is an option to treat anemia and replete iron stores, but often 
scarce supply, as well as the potential risk of blood-borne pathogens, limits its use to 
severely ill or clinically unstable patients [Kulnigg, 2006]. In view of the limitations 
associated with oral iron administration or blood transfusions, IV iron administration is 
an important therapeutic option for use in patients with IDA [Powers, 2014]. 
Multiple parenteral iron products are available. These products vary in the way that iron 
is complexed, which influences the total amount of iron that may be administered during 
a single administration. Numerous other differences differentiate the products.  However, 
all appear to effectively release iron post administration and can restore iron deficit in the 
patient. Previous studies with parenteral iron sucrose (Venofer®) have been performed in 
the pediatric population [Michaud, 2002; Pinsk, 2008; Surico, 2002]. Iron doses have 
varied in these studies, and the data demonstrates the efficacy and safety of Venofer® in 
doses up to 7 mg iron/kg (or 200 mg) administered over 3 minutes, which was shown to 
be beneficial to both the child and health care facility [Michaud, 2002]. 
Ferric Carboxymaltose has been characterized as an iron complex (Type 1) with a 
molecular mass of about 150,000 Daltons. The solution is a dark brown color with a near

Page 13 of 37 
neutral pH (5.0 to 7.0) and a physiological osmolarity permitting administration of higher 
single doses in short time periods. Although no randomized interventional studies have 
been completed with FCM in the pediatric population to date, the product has been used 
successfully to address iron deficiency in pediatric patients with ulcerative colitis and 
Crohn’s disease. A non-interventional, retrospective observational data collection 
reported FCM exposure in 79 patients aged 2 to 18 years with a mean age of 12.7 years.  
In these patients, FCM was found to be safe, well-tolerated, and effective in increasing 
Hgb, ferritin, and TSAT [Favreau, 2017]. 
The proposed study will provide safety and efficacy data on the use of FCM in pediatric 
patients (aged between 1 and 18 years) with IDA. FCM will be administered in 2 doses at 
15 mg/kg maximum single dose of 750 mg with a total maximum cumulative dose of 
1500 mg.  The ability to infuse higher doses of elemental iron should permit repletion in 
fewer overall infusions, and in doing so may ultimately permit fewer visits to the treating 
facilities.

for the treatment of IDA. After IV administration, FCM is mainly found in the liver, 
spleen, and bone marrow.  The iron slowly dissociates from the complex and can be 
efficiently used in the bone marrow for Hgb synthesis.  The carbohydrate moiety of FCM 
is metabolized by the glycolytic pathway.   
1.2.2. 
Ferric Carboxymaltose versus Other Parenteral Iron Agents 
There is considerable efficacy and safety data in the literature with respect to existing 
parenteral iron formulations [Staples, 2010]. However, prior to the approval of non-
dextran formulations, the risk of systemic adverse reactions restricted their use. FCM 
offers significant advantages compared to other available IV iron preparations.  
Iron dextran, the first parenteral iron product available in the US, has been associated 
with an incidence of anaphylaxis/anaphylactoid reactions (i.e., dyspnea, wheezing, 
hypotension, urticaria, angioedema) as high as 1.7% [Michaud, 2002].  Over the last 
20 years, 30 deaths have been attributed to the use of IV iron dextran [Fishbane, 2003].  
The high incidence of anaphylaxis/anaphylactoid reactions is believed to be caused by the 
formation of antibodies to the dextran moiety.  Although some have suggested that high 
molecular weight iron dextran is associated with a higher rate of life threatening adverse 
events and anaphylactic reactions in comparison to low molecular weight iron dextran, 
the US Food and Drug Administration (FDA) was unable to find a clear difference after 
an examination of post-marketing data, clinical trial data, death certificates, and 
emergency room diagnoses [Pinsk, 2008].  Iron dextran is limited to second line therapy 
for treatment of iron deficiency.

More recently approved IV iron formulations, including iron sucrose and iron gluconate, 
do not contain the dextran moiety.  However, they too have significant dosage and 
administration rate limitations.  If the body’s ability to sequester, store, and transport 
infused iron is overwhelmed, a reaction to excess free iron in circulation, referred to as a 
bioactive iron reaction, may occur.  Iron sucrose and iron gluconate preparations carry a 
significant risk of inducing a bioactive iron reaction when delivered at higher doses. 
These reactions are characterized by hypotension (without allergic signs) accompanied by 
pain in the chest, abdomen, flank and/or nausea, vomiting, and diarrhea [Van Wyck, 
2004].  
Due to its structure, FCM is more stable than iron gluconate and iron sucrose, and this 
results in a slower delivery of the complexed iron to endogenous iron binding sites.  
These characteristics of FCM make it possible to administer much higher single doses 
over shorter periods of time than iron gluconate or iron sucrose, resulting in the need for 
fewer administrations to replete iron stores.

TRIAL OBJECTIVE
2.1. 
Primary Objective
The primary objective of this study is to evaluate the efficacy and safety of IV FCM in 
pediatric participants who have IDA. 
3.
3.1. 
OVERALL STUDY DESIGN AND RATIONALE 
Overall Study Design
This is a single arm, open-label, multi-center, multi-national, non-randomized study that 
will evaluate the efficacy and safety of a one course treatment with FCM in participants 
who had an unsatisfactory response to oral iron in study 1VIT17044. 
Subjects will have an EOS Visit (Day 35) from the 1VIT17044 study to qualify for entry.  
Subjects will then be screened, meet all inclusion criteria, no exclusion criteria and have a 
baseline evaluation.  Based on the successful completion of the baseline evaluations, 
subjects will be enrolled and will receive the first dose of FCM (Day 0). The second 
FCM dose should occur 7 days from the first dose.  Subjects will return to the clinic 14 
and 28 days post their first dose for laboratory and safety assessments, and at 35 days 
post the first dose, participants will return to the clinic for final safety and efficacy 
assessments.  Once all assessments are complete the participant will exit the study. 
An unsatisfactory response to oral iron (i.e., an increase in Hgb of <1 g/dL from 
baseline) will be defined as non-responders to oral iron treatment.  Non-responders who 
continue to meet all inclusion criteria (including Hgb <11 g/dL) and none of the 
exclusion criteria will receive 1 course of FCM.

3.2. 
Rationale of Study Design 
The primary objective in this study is to allow participants who were randomized to 
receive oral iron in the 1VIT17044 trial and who had an unsatisfactory response to oral 
iron or those that required a concomitant intervention, (defined as, blood transfusion, use 
of IV or oral iron outside of protocol, increase in erythropoietin for any reason [Day 0 
thru Day 35 of study protocol 1VIT17044], change in IBD treatment) to receive one 
course of FCM.  This course of FCM will consist of two doses of FCM at 15 mg/kg 
(maximum single dose of 750 mg), separated by seven days. 
This study is a rollover for study 1VIT17044 which is an open label, multi-center, multi-
national, randomized, active-control parallel group study that will evaluate the efficacy 
and safety of FCM in pediatric participants, ages 1 to 18 years with iron deficiency 
anemia.

5. 
STUDY DRUG  
5.1. 
Formulation, Packaging and Storage 
The investigational medication to be used in this study [supplied by American Regent, 
Inc.] will have been prepared according to Good Manufacturing Practices (GMP). 
FCM (trade name, Injectafer®) will be supplied as 15 mL vials, containing 750 mg of iron 
as 5% w/v iron containing a polynuclear iron(III)-hydroxide 4(R)–(poly-(14)-O  -D-
glucopyranosyl)-oxy-2 (R), 3(S), 5(R), 6-tetrahydroxy-hexonate complex in a solution of 
water for injection [50 mg/mL] and will be labeled according to FDA investigational 
regulatory requirements.   
FCM must be kept in a secure place at the investigational site, and stored at room 
temperature (see United States Pharmacopeia).  The study medication should not be 
frozen.  Vials of FCM may not be used for more than 1 dose, or for more than 1 
participant.  All FCM vials and syringes (used and unused) should be kept by the study 
staff for reconciliation by the monitor. Following reconciliation, sites may destroy used 
and unused study drug on site using local procedures, provided a drug destruction policy 
is in place, or it may be returned to American Regent, Inc.  
5.2. 
Drug Administration/Regimen  
The Principal Investigator or designee will supervise administration of the study drug to 
participants. All subjects will be dosed with FCM based on the Hgb, TSAT and ferritin 
values from the last scheduled visit in the 1VIT17044 study.  
Participants will receive a dose of FCM at 15 mg/kg to a maximum single dose of 750 
mg (whichever is smaller) on Days 0 and 7 for a maximum total dose of 1500 mg. FCM

Page 19 of 37 
will be administered as either an undiluted IV push at a rate of 100 mgs (2 mL)/minute 
OR in no more than 250 mL of normal saline and infused over 15 minutes. 
5.3. 
IV Medication Precautions 
When administering FCM, the following precautions will be taken: 
 
The participant will be evaluated clinically prior to drug administration to assess the 
development of clinically-significant conditions.   
 
The vials will be visually inspected for particulate matter and discoloration before 
use.  If noted, the vial will not be used, and the Investigator or his designee will 
notify the sponsor or sponsor’s designee for replacement of the study drug, and for 
direction on the return of the unused vial. 
 
Heart rate and blood pressure will be assessed pre-, immediately post (within 5 
minutes), and 30 minutes post administration.  Participants will be discharged from 
the site by the Investigator or his or her designee only if there are no significant signs 
or symptoms 30 minutes after the administration is completed. 
 
The participant will be monitored for at least 30 minutes for serious acute reactions 
as hypersensitivity or bioactive (labile) iron reactions to non-dextran IV iron 
products have rarely been reported. The reactions include: hypotension, loss of 
consciousness, bronchospasm with dyspnea, shortness of breath, and seizures. 
 
In the event a serious acute reaction is seen, the site must have the capability to 
provide appropriate resuscitation measures. These may include IV normal 
saline, IV epinephrine, steroids, and/or antihistamines. 
5.4. 
Drug Accountability 
Investigators will keep records of the receipt, administration and return of the study drug 
(FCM).  They will not allow the study drug to be used for purposes other than as directed 
by this protocol.  The investigator agrees that he/she will not supply study medication to 
any persons other than those enrolled in the study, or to investigators not listed on the 
FDA 1572. When the study is completed, or if it is prematurely terminated, a final 
inventory of all clinical supplies must be compiled and the remainder of the unused study 
drug will be returned to American Regent, Inc., or destroyed on site, per the site’s 
documented locally accepted policies. All data regarding the study drug must be recorded 
as per the Monitoring Plan.   
5.5. 
Concomitant Medication 
All concomitant medications will be recorded in the eCRF from 30 days prior to consent.

STUDY PROCEDURES 
6.1. 
Informed Consent 
Prior to any study specific procedures, the investigator must explain to each participant 
the nature of the study, its purpose, procedures to be performed, expected duration, and 
the benefits and risks of study participation.  After this explanation, the participant (who 
for this trial is 1 -18 years old) must assent, if appropriate, and his/her legal guardian 
(who is above age of legal consent) voluntarily sign an informed consent statement 
(Required Elements of Informed Consent, 21 CFR 50.25).  The Code of Federal 
Regulations (CFR) is a codification of rules and regulations of the US government. 
Subjects who are too young to sign an informed consent form, but mature enough to 
understand the study, will provide informed assent per local law.  The subject must be 
able to understand that he or she can withdraw from the trial at any time and for any 
reason. The participant’s legal guardian will be given a copy of the signed consent form.

ASSESSMENT OF SAFETY 
7.1. 
Adverse Events 
Any untoward medical event experienced by a participant during the course of this 
clinical trial, whether or not it is related to the investigational product, at any dose, is 
considered an adverse event (AE).  
For any laboratory abnormality, the investigator will make a judgment as to its clinical 
significance. If the laboratory value is outside the normal limits and is felt to represent a 
clinically significant worsening from the baseline value, it should be considered an 
adverse event and should be recorded on the Adverse Events page of the electronic case 
report form (eCRF). If the laboratory value is outside the normal range, but not an 
adverse event, the investigator should comment on the findings (i.e., “not clinically 
significant” or “unchanged from baseline”) in the source documentation [laboratory

Page 24 of 37 
report]. All laboratory values at the EOS/Day 35 that have been deemed clinical 
significant by the Investigator should be followed until they are back into normal range. 
To quantify the severity of adverse events, the National Cancer Institute (NCI)-Common 
Terminology Criteria for Adverse Events (CTCAE), Version 5 or higher should be used 
to grade all events.  These criteria are provided in the procedure manual.   
If a NCI-CTCAE criterion does not exist, the investigator should use Table 2 to assign 
the adverse event grade. 
Table 2 
Grading of Adverse Event Severity 
Grade 
Adjective 
Description 
1 
Mild 
Asymptomatic or mild symptoms; clinical or diagnostic 
observations only; intervention not indicated. 
2 
Moderate 
Moderate; minimal, local or noninvasive intervention 
indicated; limiting age-appropriate instrumental activities 
of daily living (i.e., preparing meals, shopping for 
groceries or clothes, using the telephone, managing 
money, etc.)  
3 
Severe 
Severe or medically significant but not immediately life-
threatening; hospitalization or prolongation of 
hospitalization indicated; disabling; limiting self-care 
activities of daily living (i.e., bathing, dressing and 
undressing, feeding self, using the toilet, taking 
medications, and not bedridden.)  
4 
Life-threatening 
Life-threatening consequences; urgent intervention 
indicated. 
5 
Death 
Results in death due to the AE 
 
Timing: Non-serious AE will be reported from the initial treatment with FCM through 
the completion of the study Day 35. Adverse events will be captured 28 days post the last 
dose of study drug for participants who receive study drug and terminate early from the 
trial. This can be completed via a phone call. All ongoing AE’s related to FCM should be 
followed until they are no longer related, have taken a confounding medication or return 
to baseline grade. 
Relationship (Causality): The Investigator will be asked to document his/her opinion of 
the relationship of the event to the study drug* as follows: 
 NONE 
There is no evidence of any causal relationship 
 UNLIKELY 
There is little evidence to suggest there is a causal 
relationship. There is another reasonable explanation for the 


CONFIDENTIAL

Protocol No.: 1VIT18045 
 
Final version: 1.0 26 April 2019 
Page 25 of 37 
event (e.g., the participant’s clinical condition, other 
concomitant treatments). 
 POSSIBLE 
There is some evidence to suggest a causal relationship (i.e. 
there is a reasonable possibility that the adverse experience 
may have been caused by the agent). However, the influence 
of other factors may have contributed to the event (e.g., the 
participant’s clinical condition, other concomitant events). 
 PROBABLE 
There is evidence to suggest a causal relationship, and the 
influence of other factors is unlikely 
*For the purpose of this trial, study drug is defined as FCM. 
7.2. 
Reporting of Adverse Events 
Adverse experiences will be elicited by nonspecific questions such as “Have you noticed 
any problems?”  Participants will be encouraged to report adverse events at their onset.   
Any adverse experience spontaneously reported by, elicited from the participant, or 
observed by the physician or study staff, shall be recorded on the appropriate Adverse 
Event page of the eCRF. The investigator will record the date and time of onset, severity, 
the relationship to study medication, the date and time of resolution (or the fact that the 
event is still continuing), the action taken, and the outcome of the adverse experience on 
the Adverse Event page of the eCRF. Whenever possible, the investigator should group 
together, into a single term, signs and symptoms which constitute a single diagnosis. For 
example, cough, rhinitis and sneezing might be grouped together as "upper respiratory 
infection."  
7.3. 
Serious Adverse Events 
Definition: An adverse event is classified as SERIOUS if it meets any one of the 
following criteria:  
 
Death 
 
Life-Threatening: The participant was at substantial risk of dying at the time of the 
adverse event or it is suspected that the use or continued use of the product would 
result in the participant's death. 
 
Hospitalization (initial or prolonged): Required admission to the hospital or 
prolongation of a hospital stay. 
 
Disability: Resulted in a significant, persistent, or permanent change, impairment, 
damage or disruption in the participant’s body function/structure, physical activities 
or quality of life. 
 
Congenital Anomaly/Birth Defect. 


CONFIDENTIAL 
American Regent, Inc. 
 
Protocol No.: 1VIT18045 
 
Final version: 1.0 26 April 2019 
Page 26 of 37 
 
Important medical events: Other medically important events that, in the opinion of 
the investigator, may jeopardize the participant or may require intervention to 
prevent one of the other outcomes listed above. 
A distinction should be drawn between SAE and severe AE.  A SAE is a major 
experience of its type.  A SAE is not necessarily serious: e.g. nausea, which persists for 
several hours, may be considered severe nausea, but it is not an SAE.  On the other hand 
a stroke, which results in only a limited degree of disability may be considered a mild 
stroke, but would be a SAE. 
Timing: All SAEs will be reported from the day of initial treatment with *study drug 
through the completion of the study Day 35.  Serious adverse events will be captured 28 
days post the last dose of study drug for participants who terminate early from the trial. 
This can be completed via a phone call. Hospitalization resulting from a historical 
condition (present prior to initial treatment with study drug or prescheduled prior to 
treatment with study drug) that has not increased in severity or led to prolongation of 
hospital stay should not be considered a SAE. All reported SAE should be followed until 
they are no longer serious or return to baseline grade.   
Reporting: Any SAE, starting with the first dose of study drug, that is to be reported (as 
outlined in Timing section above) must be reported immediately (within 24 hours of 
learning of the event) to American Regent, Inc. by telephone, email and/or fax of the 
written SAE report form to the contacts listed below: 
Safety Monitor 
American Regent, Inc. 
Phone: (800) 734-9236 
Fax: (610) 650-0170 
Email: pv@americanregent.com 
The local investigator is responsible for reporting SAEs to their local Institutional Review 
Board (IRB)/ Ethics Committee based on local reporting guidelines (which may be 
different than those specified in this protocol). The responsible investigator should 
institute appropriate diagnostic and therapeutic measures and keep the participant under 
observation for as long as is medically indicated.

STATISTICS 
Continuous variables will be summarized in terms of the number of observations, mean, 
standard deviation (SD), median, Q1, Q3, minimum and maximum. Other descriptive 
statistics (e.g., coefficient of variation) may be reported when appropriate. Categorical 
variables will be summarized using frequency counts and percentages.   
Generally, data will be summarized by nominal visit.  However, data from both 
unscheduled and scheduled will be used for determination of last observed value, and in 
worst- or best-case changes and/or shifts from baseline. Assessment windows will not be

defined for the purpose of classifying measurements obtained outside scheduled 
assessment times. 
A complete description of the statistical analyses and methods will be available in a 
Statistical Analysis Plan (SAP), which will be finalized before the database is locked. 
8.1. 
Stratification/Randomization 
This is a non-randomized, single arm study. 
8.2. 
Analysis Populations 
Safety Population 
The safety population will consist of all participants who received at least one dose of 
study drug.   
8.3. 
Disposition and Baseline Characteristics 
The number of participants in each investigative site will be summarized.  The number of 
participants who are screened, treated, prematurely discontinue, and complete the study 
will be summarized.    
The clinical team will identify deviations and the deviations will be identified in the 
database.  Participants with clinically important protocol deviations will be summarized. 
Demographics and baseline characteristics will be summarized using descriptive statistics 
or frequency counts. 
8.4. 
Endpoints and Definitions 
8.4.1. 
Primary Endpoint 
The primary endpoint is the change in Hgb from baseline to day 35.  Descriptive statistics 
will be provided for the baseline Hgb, the day 35 Hgb, and the within-participant change 
from baseline.  The change in Hgb from baseline to day 35 will be analyzed using paired 
t-tests. 
8.4.2. 
Secondary Endpoints 
Secondary efficacy endpoints include: 
 
Change in ferritin from baseline to Day 35 
 
Change in TSAT from baseline to Day 35  
 
Changes from baseline in Hgb, ferritin, TSAT, and CHr throughout the study 
Details of analyses for these endpoints will be outlined in the SAP.

8.4.3. 
Missing Data 
A participant who withdraws from the study for any reason will be included in the 
analyses regardless of time on study. Methods for handling withdrawals and missing data 
will be specific to each endpoint to be analyzed. Missing data will not be imputed for 
descriptive statistical summaries in safety or efficacy. Details will be provided in the 
SAP. 
8.5. 
Analyses of Safety 
8.5.1. 
Study Drug Exposure 
The number of infusions and total administered amount of iron will be summarized 
descriptively.  
8.5.2. 
Adverse Events 
Adverse events will be coded by system organ class (SOC) and preferred term (PT) using 
the Medical Dictionary for Regulatory Activities (MedDRA) dictionary. 
The number and percent of participants who report treatment emergent AE (TEAE) will 
be summarized. A TEAE is an event with onset date on or after the study drug start date.  
Adverse event summaries will exclude preferred terms that describe asymptomatic serum 
ferritin, TSAT, and reticulocyte values (or changes). This approach is justified by the 
reporting of these values in efficacy summaries and is consistent with the protocol-
defined reporting standards for Hgb/hematocrit (Hct) and low iron indices.  For the 
purposes of this study, non-serious anemia (Hgb or Hct below the normal range or 
worsened from baseline) or iron deficiency (iron indices below the normal range or 
worsened from baseline) will not be considered adverse events.  Anemia or iron 
deficiency will be considered end points if an intervention is required. 
The adverse event profile will be characterized with severity (as graded by the NCI-
CTCAE) and relationship (unrelated and related) to study drug. Related adverse events 
will be events that are possibly or probably related to treatment in the investigator’s 
judgment.  
Participants who report the same preferred term on multiple occasions will be counted 
once for the preferred term: under the highest severity when summarized by severity and 
under the closest relationship to study drug when summarized by relationship. If a 
participant reports multiple preferred terms for a SOC, the subject will be counted only 
once for that SOC.   
The number and percent of participants who report treatment-emergent serious adverse 
events will be similarly summarized for each treatment group. The number and percent of 
participants who report treatment-emergent adverse events resulting in discontinuation of 
study drug will be similarly summarized for each treatment group.

Page 29 of 37 
8.5.3. 
Adverse Events of Special Interest 
Adverse events (AEs) of special interest include hypersensitivity, hypersensitivity-like 
reactions, and cardiovascular events. Hypersensitivity and hypersensitivity-like reactions 
will be identified using standardized MedDRA queries. Cardiovascular events will be 
identified using the SOCs for cardiac disorders and vascular disorders. 
The overviews and summaries that are provided for all TEAEs will also be provided for 
the AEs of special interest. In addition, the time to onset and time to recovery will be 
summarized. 
8.5.4. 
Clinical Laboratory Findings 
Clinical laboratory variables will be presented in two ways.  First, the mean change from 
baseline to each scheduled visit will be summarized. Second, the number and percent of 
participants with treatment-emergent potentially clinically significant (PCS) laboratory 
values will be tabulated. Treatment-emergent PCS laboratory tests are those in which the 
baseline value is normal and post-baseline value is abnormal (i.e., meets Grade III or 
Grade IV toxicity criteria from the NCI-CTCAE Version 5 or higher).  Baseline will be 
defined as the last value obtained before receiving study drug. 
No formal statistical tests will be performed.   
8.5.5. 
Vital Signs 
The change in vital signs (sitting heart rate and blood pressure) from pre-infusion to each 
post-infusion time point will be summarized descriptively on each dosing day. 
8.5.6. 
Sample Size Rationale 
There were no sample size estimations for this study.  The current study is a rollover for 
study 1VIT17044. There will be a maximum of approximately 36 participants from study 
1VIT17044 who had an unsatisfactory response to oral iron or required an intervention. 
9.

SUMMARY OF THE STUDY DESIGN 
1.3.1 
General Study Design and Plan 
This is a single arm, open-label, multi-center, multi-national, non-randomized study that will 
evaluate the efficacy and safety of a one course treatment with FCM in participants who had an 
unsatisfactory response to oral iron in study 1VIT17044. 
Subjects will have an EOS Visit (Day 35) from the 1VIT17044 study to qualify for entry. 
Subjects will then be screened, meet all inclusion criteria, no exclusion criteria and have a 
baseline evaluation. Based on the successful completion of the baseline evaluations, subjects will 
be enrolled and will receive the first dose of FCM (Day 0). The second FCM dose should occur 7 
days from the first dose. Subjects will return to the clinic 14 and 28 days post their first dose for 
laboratory and safety assessments, and at 35 days post the first dose, participants will return to 
the clinic for final safety and efficacy assessments. Once all assessments are complete the 
participant will exit the study. 
An unsatisfactory response to oral iron (i.e., an increase in Hgb of <1 g/dL from baseline) will 
be defined as non-responders to oral iron treatment. Non-responders who continue to meet all 
inclusion criteria (including Hgb <11 g/dL) and none of the exclusion criteria will receive 1 
course of FCM.

Stratification/Randomization 
This is a non-randomized, single arm study. 
 
1.3.3 
Sample Size and Statistical Power Considerations 
There were no sample size estimations for this study. The current study is a rollover for study 
1VIT17044. There will be a maximum of approximately 36 participants from study 1VIT17044 
who had an unsatisfactory response to oral iron or required an intervention. 
 
2. 
STATISTICAL METHODS 
2.1 
GENERAL CONSIDERATIONS 
Analysis datasets will be produced according to CDISC standards. All study-collected data will 
be summarized in tables or graphs. Listing will be produced when appropriate and all ICH- 
required listings will be produced. 
 
Continuous variables will be summarized in terms of the number of observations (n), mean, 
standard deviation (SD), median, quartiles (Q1 and Q3), minimum (min), and maximum (max) 
values. Other descriptive statistics (e.g., coefficient of variation) may be reported when 
appropriate. Analysis of categorical variables will include frequency counts and percentages. 
Unknown and missing data may be presented as a separate category and the denominator will 
include unknown or missing values as appropriate. If applicable, hypothesis testing will be 
carried out at the two-sided α=0.05 level unless otherwise specified; 2-sided 95% confidence 
intervals (CIs) will be presented, where specified. 
 
Generally, data will be summarized by nominal visit. However, data from both unscheduled and 
scheduled will be used for determination of last observed value, and in worst- or best-case 
changes and/or shifts from baseline. Assessment windows will not be defined for the purpose of 
classifying measurements obtained outside scheduled assessment times. 
 
2.1.1 
Reporting Precision 
Summary statistics will be presented to the following degree of precision, unless otherwise 
specified: 
 
Statistics 
Degree of Precision 
Mean, Geometric mean, Median, 
Quartiles, Confidence limit boundaries 
One decimal place more than the raw data. 
Standard deviation, Standard error 
Two decimal places more than the raw data. 
Minimum, Maximum 
The same as the raw data. 
p-value 
Rounded to 4 decimal places and therefore 
presented as 0. xxxx; p-values smaller than

0.0001 as ‘<0.0001’; p-values greater than 0.9999 
as ‘>0.9999’. 
Percentage 
One decimal place. A percentage of 100% will be 
reported as 100%. Percentages of zero will be 
reported as 0. 
 
For weight and height, one decimal place will be used for summary statistics. Fractional numeric 
values will be presented with a zero to the left of the decimal point (for example, 0.12 – 0.30). 
 
2.2 
DEFINITIONS OF ANALYSIS POPULATIONS (ANALYSIS SETS) 
2.2.1 
Safety Population 
The safety population will consist of all participants who received at least one dose of study drug 
(IV FCM). 
 
2.3 
DEFINITIONS AND CONVENTIONS FOR DATA HANDLING 
2.3.1 
Baseline Definition 
For evaluations collected at multiple time points, the baseline will be defined as the last value 
obtained before the first dose of study drug. 
 
2.3.2 
Study Day 
Study Day will be calculated relative to the day of first dose (defined as Day 1). 
 
If the assessment (or event) date falls on or after the date of first dose then 
Study Day = Assessment Date – Date of First Dose + 1 
 
If assessment date falls before the date of first dose then 
Study Day = Assessment Date – Date of First Dose 
 
In the case of adverse events or concomitant medications where the assessment date is partially 
or completely missing, Study Day and any corresponding durations will follow the conventions 
given in Section 2.3.4. 
 
2.3.3 
Time Windows for Analysis 
No assessment windows will be defined for the purpose of classifying measurement obtained 
outside scheduled assessment times. The summary by visit will be based on the observations at 
scheduled visits only. Data from both unscheduled and scheduled will be used for determination 
of last observed value, and in worst- or best-case changes and/or shifts from baseline.

2.3.4 
Handling of Missing Data 
A participant who withdraws from the study for any reason will be included in the analyses 
regardless of time on study. Methods for handling withdrawals and missing data will be specific 
to each endpoint to be analyzed. Missing data will not be imputed for descriptive statistical 
summaries in safety or efficacy. 
 
For statistical inferential (paired t-tests) analyses, missing data will be imputed using last 
observation carried forward (LOCF) method for hemoglobin and other efficacy endpoints. e.g. 
for primary endpoint, hemoglobin, when Day 35 data is missing (subject has discontinued before 
Day 35, or measurement not taken at Day 35 though subject was not discontinued), Day 28 or 
last unscheduled result will be carried forward. If there is no post-baseline value observed, the 
worst value obtained from Day 35 of all subjects in the safety population will be used. The worst 
value is defined as the lowest value for hemoglobin, ferritin, TSAT and reticulocyte hemoglobin 
content. 
 
Dates missing the day or both day and month of the year will adhere to the following 
conventions to classify TEAE and to classify prior/concomitant medications. 
 
 A medication with a completely missing start date will be considered a prior medication. A 
medication with a completely missing stop date will be considered a concomitant 
medication. 
 
 If complete AE onset date is missing and AE end date is on or after the first dose date then 
it will be counted as a treatment emergent AE (TEAE) for the study. If complete AE onset 
date is missing and AE end date is before the first dose date then it will not be counted as 
a TEAE for the study. 
 
 If an AE or a medication has a partial missing start or stop date, the following rules will be 
used for imputation: 
 
o If year is present but month and day are missing, impute start date as January 1 of that 
year or first dose date if the year is the same as the year of first dose date and impute 
stop date as December 31 of that year. 
 
o If year and day are present but month is missing, impute start month as January or the 
month of the first dose date if the year is the same as the year of first dose date and 
impute stop month as December. 
 
o If year and month are present but day is missing, impute start date as first day of that 
month or first dose date if the year and month are the same as the year and month of 
first dose date and impute stop date as last day of that month.

2.4 
POOLING OF CENTERS 
The study centers are not planned to be used as a stratification factor nor a covariate in the 
statistical modeling and testing, therefore it is not necessary to pool small centers together. 
 
2.5 
ANALYSIS SOFTWARE 
All summaries and statistical analyses will be generated using SAS® version 9.4 or higher. 
 
3. 
STUDY SUBJECTS 
3.1 
DISPOSITION OF SUBJECTS 
Disposition will be summarized for all screened subjects and the number of subjects in Safety 
Population will be summarized in each investigative site. 
 
The disposition will include the following: 
 Participants who are screened 
 Participants who are included in Safety Population 
 Participants who complete the study 
 Participants who discontinue the study 
 
The number and percent of subjects will be summarized for each reason for premature 
discontinuation. 
 
3.2 
PROTOCOL DEVIATIONS 
The clinical team will identify deviations and the deviations will be identified in the database. 
The number and percent of participants with clinically important protocol deviations will be 
summarized for each type of deviation based on the safety population. 
 
4. 
DEMOGRAPHY AND BASELINE CHARACTERISTICS 
4.1 
DEMOGRAPHY AND BASELINE CHARACTERISTICS 
Demography data such as sex, age, age group (1 to <12 and ≥12 to 18 years), race, ethnicity, 
body height, body weight, BMI and BMI group (underweight ≤18.5, 18.5 < normal weight≤ 
24.9, 25 < overweight ≤ 29.9, obesity = BMI of 30 or greater) will be summarized with 
descriptive statistics or frequency counts for all patients in the safety populations. 
 
4.2 
MEDICAL HISTORY 
Medical history will be coded with the Medical Dictionary for Regulatory Activities (MedDRA) 
Terminology. Events will be coded to System Organ Class (SOC) and preferred term (PT) using 
MedDRA Version 22.0 or higher. The number and percent of subjects with clinically significant 
medical history at screening will be summarized by SOC and PT for the safety populations.

4.3 
PRIOR AND CONCOMITANT MEDICATION 
Prior medications are defined as medications that started prior to the first dose of study drug. 
Concomitant medications are defined as medications (other than the study drug) taken on or after 
the first dose of the study drug during the entire study. Medications started before the first dose 
of study drug and continuing at the time of the first dose of study drug are considered both prior 
medication and concomitant medication. As for the medications that stopped with end date prior 
to study drug start date will be considered as prior medications. Partial dates for 
prior/concomitant medication will be classified based on rules in Section 2.3.4. 
 
All investigator terms for medications recorded on the CRF will be coded using the World 
Health Organization (WHO) Anatomical Therapeutic Chemical (ATC) drug dictionary 
(WHODrug, March 2019 B3). Summaries of prior and concomitant medications will be provided 
by level 3 ATC classification and preferred term using frequency and percentages for the safety 
population. If ATC level 3 is not applicable, then the level 2 ATC will be used. 
 
5. 
STUDY DRUG 
5.1 
TREATMENT COMPLIANCE 
As for each subject, the individual compliance rate will be summarized by descriptive statistics 
for the safety population. 
 
FCM Compliance = (total dose of iron administered/target dose) ×100 
 
5.2 
EXTENT OF EXPOSURE 
 
The total calculated FCM dose to be given (mg), the total dose of elemental iron administered 
(mg), the number of infusions and treatment duration (days) will be summarized descriptively. 
 
6. 
EFFICACY ANALYSES 
All primary and secondary efficacy analyses will be based on the safety population unless 
otherwise specified. Missing data will be imputed per Section 2.3.4 for primary and secondary 
efficacy endpoints (no imputation for descriptive statistical summaries). P-values to determine 
the mean difference between baseline and Day 35 will be reported. The mean difference and 
corresponding 95% confidence interval will be tabulated where appropriate. 
 
6.1 
PRIMARY EFFICACY ANALYSIS 
6.1.1 
Change in Hgb from baseline to Day 35 
The primary efficacy endpoint is the change in Hgb from baseline to day 35. The actual value of 
Hgb on baseline, Day 35, and change from baseline to Day 35 will be summarized via 
descriptive statistics.

The change in Hgb from baseline to Day 35 will be assessed using paired t-tests (two-sided test, 
α=0.05). Baseline Hgb will be defined as the last Hgb obtained before the first dose. Missing 
value will be imputed using LOCF as specified in Section 2.3.4. 
 
6.2 
SECONDARY EFFICACY ANALYSES 
6.2.1 
Change in ferritin from baseline to Day 35 
The actual value of ferritin on baseline, Day 35, and change from baseline to Day 35 will be 
summarized via descriptive statistics. 
 
The change in ferritin from baseline to day 35 will be assessed using paired t-tests (two-sided 
test, α=0.05). Baseline ferritin will be defined as the last ferritin obtained before the first dose. 
Missing value will be imputed using LOCF as specified in Section 2.3.4.

Change in TSAT from baseline to Day 35 
The actual value of TSAT on baseline, Day 35, and change from baseline to Day 35 will be 
summarized via descriptive statistics. 
 
The change in TSAT from baseline to day 35 will be assessed using paired t-tests (two-sided test, 
α=0.05). Baseline TSAT will be defined as the last TSAT obtained before the first dose. Missing 
value will be imputed using LOCF as specified in Section 2.3.4. 
 
6.2.3 
Change in Hgb, ferritin, TSAT and Reticulocyte Hemoglobin Content from 
baseline throughout the Study 
The actual value of Hgb, ferritin, TSAT and reticulocyte hemoglobin content (CHr) on baseline, 
each post-baseline visit (Day 7, 14, 28 and 35), and change from baseline to each post-baseline 
visit will be summarized via descriptive statistics. 
 
7. 
SAFETY ANALYSES 
All safety analyses will be performed on the safety population. Safety assessments include: 
 
 Extent of exposure 
 Adverse events 
 Laboratory assessments (hematology, iron indices, chemistry, and other) 
 Vital signs 
 
Baseline of clinical laboratory findings will be defined as the last value obtained before the first 
dose of study drug. 
 
7.1 
ADVERSE EVENTS 
 
Adverse events (AEs) will be coded by System Organ Class (SOC) and Preferred Term (PT) 
using the Medical Dictionary for Regulatory Activities (MedDRA) dictionary. Adverse event

summaries will exclude preferred terms that describe asymptomatic serum ferritin, TSAT, and 
reticulocyte values (or changes). This approach is justified by the reporting of these values in 
efficacy summaries and is consistent with the protocol-defined reporting standards for 
hemoglobin/hematocrit and low iron indices. For the purposes of this study, non-serious anemia 
(hemoglobin or hematocrit below the normal range or worsened from baseline) or iron 
deficiency (iron indices below the normal range or worsened from baseline) will not be 
considered adverse events. Anemia or iron deficiency will be considered end points if an 
intervention is required. 
 
A treatment-emergent adverse event (TEAE) is defined as an event with onset date on or after the 
study drug start date. Partial date TEAE classification rules refer to Section 2.3.4. Only TEAEs 
will be included in summary tables. 
 
The incidence of TEAEs will be summarized as the number (percentage) of subjects with TEAEs 
within SOC and PT. Subjects who report the same PT on multiple occasions will be counted once 
for the PT: under the highest severity (severe > moderate > mild) CTCAE when summarized by 
severity and under the closest relationship (probably related > possibly related > unlikely related 
> none) to study drug when summarized by relationship. If a subject reports multiple PT for a 
SOC, the subject will be counted only once for that SOC. Events with unknown severity or 
relationship will be counted as unknown. 
 
TEAEs will be summarized as below. 
 An overview table, including number of subjects with 
o TEAEs 
o serious TEAEs 
o study drug related TEAEs 
o study drug related Serious TEAEs 
o TEAEs by severity 
o TEAEs leading to study drug discontinuation or withdrawal from study 
o TEAEs leading to death 
 TEAE by SOC 
 TEAE by PT 
 TEAE by SOC and PT 
 TEAE by SOC, PT, and Severity (CTCAE) 
 Study drug related TEAEs by SOC, PT 
 Serious TEAEs by SOC and PT 
 Study drug related serious TEAEs by SOC and PT

 TEAEs leading to study drug discontinuation or withdrawal from study by SOC and PT 
 TEAEs leading to death by SOP and PT 
Unless otherwise stated, all TEAE tables will be sorted by SOC and PT in decreasing frequency 
of the number and percentage of subjects. 
 
7.1.1 
Adverse Events of Special Interest 
 
Adverse events of special interest include hypophosphatemia, hypersensitivity/anaphylactoid 
reactions, injection/infusion site reactions, and cardiovascular events. The search strategy will be 
identified as follows: 
 
 TEAEs of hypophosphatemia: 
o MedDRA PT Blood phosphorus decrease 
o MedDRA PT Blood phosphorus abnormal 
o MedDRA PT Hypophosphataemia 
o MedDRA PT Hypophosphataemic rickets 
o MedDRA PT Rickets familial hypophosphataemic 
 
 TEAEs indicative of hypersensitivity/anaphylactoid reactions: 
o SMQ Anaphylactic reaction 
o SMQ Angioedema 
o PT Hypersensitivity 
 
 TEAEs of injection/infusion site reactions: 
o MedDRA HLT Infusion site reactions 
o MedDRA HLT Injection site reactions 
o MedDRA HLT Administration site reactions NEC 
o MedDRA PT Infusion related reaction 
 
 Cardiovascular TEAEs: 
o Cardiovascular disorders SOC 
o Vascular disorders SOC 
The AEs of special interest will be summarized as below: 
 
 Treatment-emergent AESI by SOC and PT 
 Serious treatment-emergent AESI by SOC, PT 
 Serious or severe treatment-emergent AESI by SOC and PT 
7.2 
CLINICAL LABORATORY PARAMETERS 
Laboratory assessments include hematology, clinical chemistry, and iron indices: 
 
 Hematology: Hgb, Hct, RBC, WBC, MCV, MCH, MCHC, RDW, platelets, differential

count, reticulocyte count and CHr 
 
 Clinical chemistry: sodium, potassium, chloride, BUN, creatinine, albumin, alkaline 
phosphatase, total bilirubin, GGT, AST, ALT, LDH, calcium, phosphorus, glucose, 
bicarbonate and magnesium. 
 
 Iron indices: serum iron, serum ferritin, and total iron binding capacity (TIBC), and 
percentage serum transferrin saturation (TSAT). 
 
 Other: Serum pregnancy test 
All laboratory parameters will be presented in conventional units. The actual value and mean 
change from baseline to each scheduled visit will be summarized using descriptive statistics for 
each laboratory test group above. 
 
Time course table for serum phosphate will be constructed for subjects in safety population. 
Descriptive statistics of days to first value of specified CTC grade and days to return to normal 
will be summarized. Only the subjects with a normal serum phosphate baseline value will be 
included in this table. 
 
The number and percent of subjects with treatment-emergent potentially clinically significant 
(PCS) laboratory values after baseline will be summarized by visit. The denominator is all 
subjects with normal baseline and at least one post baseline assessment in the safety population 
and the numerator is the number of subjects with PCS (i.e., meets Grade 3 or Grade 4 AE scale 
defined in Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric 
Adverse Events, Version 2.1 from March 2017 (Division of AIDS, National Institute of Allergy 
and Infectious Diseases, National Institutes of Health, US Department of Health and Human 
Services)) at any post-baseline visit. 
 
Shift from baseline AE grade to maximum post-baseline AE grade, and shift from baseline to the 
last visit in terms of AE grade will be summarized, separately. 
 
The AE grade for Chemistries and Hematology are defined in Appendix 1.1. BUN, hematocrit, 
bands and iron indices do not have adverse event scales available and are not evaluated 
separately as possible AEs.

VITAL SIGNS AND PHYSICAL EXAMINATION FINDINGS 
7.3.1 
Vital Signs 
 
Vital signs will be collected including sitting body temperature, blood pressure (BP) and heart 
rate. On study drug dosing days BP and heart rate will be collected pre-dosing, immediately 
(within 5 minutes) post, and 30 minutes post dosing, and body temperature will be collected on 
each dosing day. The actual value and the change in vital signs (including sitting heart rate and 
blood pressure) from pre-infusion to each post-infusion time point will be summarized 
descriptively on each dosing day. Markedly abnormal values should be determined by PALS

Physical Examination 
 
Physical examination (PE) results were collected at Day 0 and Day 35 including six body 
systems, i.e. skin, cardiovascular, pulmonary/respiration, abdominal, central nervous system and 
musculoskeletal/extremities. Each component of the baseline physical examination will be 
recorded as normal or abnormal. Each component of the post baseline physical examinations will 
be recorded as No Change from Baseline PE or Change from Baseline PE. The number and 
percent of subjects who have normal, abnormal and significant changes at each visit will be

SUMMARY OF MAJOR CHANGES IN THE PLANNED ANALYSES 
 
Compared with the study protocol (03 December 2019 Administrative Change 1), below items 
are the major changes made in this SAP: 
 
1. The LOCF imputation method was proposed for paired t-test for primary and secondary 
efficacy endpoints in SAP. 
 
2. The scale defined in Division of AIDS (DAIDS) Table for Grading the Severity of Adult and 
Pediatric Adverse Events, Version 2.1 from March 2017 (Division of AIDS, National Institute of 
Allergy and Infectious Diseases, National Institutes of Health, US Department of Health and 
Human Services) will be used to identify abnormal clinical laboratory values instead of toxicity 
criteria from the National Cancer Institute Common Terminology Criteria version 5 for Adverse 
Events specified in the protocol.
