Brief summary:
Iron deficiency is the most common cause of anemia in pregnancy worldwide, and, when severe, can have serious consequences for mothers and babies. While treatment of iron-deficiency anemia with iron supplementation is recommended, treatment strategies remain controversial: the American College of Obstetrics and Gynecology recommends oral iron supplementation with parental iron reserved for the rare patient who cannot tolerate or will not take oral iron, while United Kingdom professional organizations recommend a more liberal use of parenteral iron. The reason for these disparate recommendations is that few high-quality studies comparing oral to parenteral iron have been conducted in developed countries, and the potential impact of parental iron treatment on obstetric and perinatal outcomes remains unclear. We propose the first randomized-controlled trial in the United States describing the effectiveness and safety of treating pregnant women with iron-deficiency anemia with a protocol including parenteral iron compared with a protocol based on oral iron.

Detailed description:
Iron deficiency is the most common cause of anemia in pregnancy worldwide, and, when severe, can have serious consequences for mothers and babies. In the United States, anemia affects nearly 20% of pregnancies and the majority is iron-deficiency anemia. Therefore, treatment of iron-deficiency anemia with iron supplementation is recommended.1 However, there is controversy about the treatment strategies.

The American College of Obstetrics and Gynecology recommends oral iron supplementation for iron-deficiency anemia in pregnancy, with parental iron reserved only for the "rare patient who cannot tolerate or will not take oral iron" (1) Conversely, guidelines from the United Kingdom. are more liberal on the use of parental iron for the treatment of iron-deficiency anemia in pregnancy (2). Both treatment guidelines are based on limited data regarding the risks and benefits of parental iron for treatment of iron-deficiency anemia in pregnancy. The majority of randomized trials were conducted in developing country settings. In fact, few high-quality studies have been conducted in developed countries, and none has been conducted in the United States Moreover, there is limited data from prior studies on the impact of parental iron treatment on perinatal outcomes. The most recent Cochrane review including mostly from trials conducted in low-income countries found that, although parenteral iron improved hemoglobin levels and iron stores than the oral route, no clinical outcomes were assessed and there were insufficient data on adverse effects (3). The authors concluded that "large, good quality trials, assessing clinical outcomes including adverse effects … are required" (3).

This randomized controlled trial aims to assess the effectiveness and safety of treating pregnant women with iron-deficiency anemia with a protocol including parenteral iron compared with a protocol based on oral iron. We hypothesize that treating iron-deficiency anemia with parental iron is associated with improved maternal and neonatal outcomes compared with a protocol based on oral iron. To increase generalizability of the findings, we will use broad inclusion criteria and analyze data using the intention-to-treat principle.

Study Protocol 
Intravenous Iron for Iron-Deficiency Anemia in Pregnancy: A Randomized Controlled Trial (IVIDA) 
PI: Dr. Methodius Tuuli; Indiana University 
Version 6.2 
NCT03438227 
SYNOPSIS  
Objective: To assess the effectiveness and safety of treating iron-deficiency anemia in pregnant women with 
intravenous iron compared to oral iron. 
Background: Iron deficiency is the most common cause of anemia in pregnancy worldwide, and, when severe, can 
have serious consequences for mothers and babies. In the U.S., anemia affects nearly 20% of pregnancies, and 
the majority are iron-deficiency anemia. While treatment of iron-deficiency anemia with iron supplementation is 
recommended, treatment strategies remain controversial. The American College of Obstetrics and Gynecology 
(ACOG) recommends oral iron supplementation for iron-deficiency anemia in pregnancy and postpartum, with 
intravenous iron reserved for the rare patient who cannot tolerate or will not take oral iron. Conversely, UK 
professional organizations recommend a more liberal use of intravenous iron for the treatment of iron-deficiency 
anemia in pregnancy and postpartum. The reason for these disparate recommendations is that few high-quality 
studies comparing oral to intravenous iron have been conducted in developed countries, and the potential impact 
of intravenous iron treatment on obstetric and perinatal outcomes remains unclear. The most recent Cochrane 
review—mostly of trials conducted in low-income countries—found that, although intravenous iron more effectively 
improved hemoglobin levels and iron stores compared to oral iron, no clinical outcomes were assessed and there 
were insufficient data on adverse effects. Thus, there is a need for a well-designed trial to clarify whether intravenous 
iron should be used more liberally for the treatment of iron-deficiency anemia in pregnancy in the U.S. 
Study design: Open-label, randomized controlled trial  
Primary outcome: Maternal anemia (hemoglobin (Hgb) <11mg/dl) on admission for labor & delivery  
Secondary outcomes:  
1. Safety (infusion reactions) 
2. Maternal outcomes (Hgb, serum ferritin, blood transfusion, mode of delivery) 
3. Neonatal outcomes (gestational age at delivery, infant birth weight, cord gases, umbilical artery lactate, 
APGAR scores, cord blood Hgb & ferritin, neonatal morbidities, postpartum disposition)

Randomization and treatment: Patients who meet all inclusion criteria and no exclusion criteria will be enrolled 
and randomized in a 1:1 ratio using a computer-generated randomization sequence to one of two treatment 
protocols: 
1. Oral Iron Supplement- Oral iron supplementation (ferrous sulfate 325mg once daily to three times daily through 
delivery) 
2. Intravenous Iron- Intravenous iron infusion (1000mg of intravenous iron dextran; given as a single dose after 
enrollment as close as possible to 24 weeks gestation). If iron dextran is unavailable due to drug shortage, 
ferumoxytol will be substituted; 510 mg IV will be administered followed by a second dose (510 mg IV) 3 to 8 days 
after the initial dose. 
Procedures: All patients presenting for prenatal care will have workup for anemia with repeat CBC at 24 to 28 
weeks gestation per standard of care. Patients found to have iron-deficiency anemia (Hgb <10 g/dL and ferritin 
<30ug) at 24 – 28 weeks and who meet all other inclusion and exclusion parameters will be eligible to be approached 
for the study. In addition, patients who do not receive standard anemia screening but are diagnosed at 28 – 34 
weeks gestation with iron-deficiency anemia (hemoglobin<10mg/dl and ferritin <30ug) will be eligible for the study. 
Subjects will be randomized to one of the two treatment groups (oral or intravenous iron supplementation). Study 
patients will have Hgb and ferritin drawn at delivery. Their neonates will have Hgb and ferritin drawn via cord blood 
at delivery. If a cord gas or umbilical artery lactate level is drawn out of clinical necessity, this data will be collected 
also. Chart abstraction will be used to assess additional maternal and neonatal outcomes. Pregnancy, labor and 
delivery management will be per standard obstetric practice.  
Sample Size: 120 subjects over an estimated 15 - 18 months.

BACKGROUND  
Iron deficiency is the most common cause of anemia in pregnancy worldwide, and, when severe, can have serious 
consequences for mothers and babies. In the U.S., anemia affects nearly 20% of pregnancies and the majority are 
iron-deficiency anemia. Patients on oral iron for iron-deficiency anemia with a Hgb<11mg/dl at the time of delivery 
have a 3-fold increased risk of peripartum blood transfusion (3.8% vs 1.3%, RR 2.90, 95% CI 1.97, 4.36) based on 
institutional data from Washington University in St. Louis. Therefore, treatment of iron-deficiency anemia with iron 
supplementation is recommended.1 However, there is controversy about the treatment strategies. 
 
The American College of Obstetrics and Gynecology recommends oral iron supplementation for iron-deficiency 
anemia in pregnancy, with intravenous iron reserved only for the “rare patient who cannot tolerate or will not take 
oral iron.”1 Conversely, guidelines from the U.K. are more liberal on the use of intravenous iron for the treatment of 
iron-deficiency anemia in pregnancy.2 Both treatment guidelines are based on limited data regarding the risks and 
benefits of intravenous iron for treatment of iron-deficiency anemia in pregnancy. The majority of randomized trials 
were conducted in developing country settings. In fact, few high-quality studies have been conducted in developed 
countries, and none has been conducted in the U.S. Moreover, there is limited data from prior studies on the impact 
of intravenous iron treatment on perinatal outcomes. The most recent Cochrane review including mostly trials 
conducted in low-income countries found that, although intravenous iron improved hemoglobin levels and iron 
stores more than the oral route, no clinical outcomes were assessed and there were insufficient data on adverse 
effects. The authors concluded that “large, good quality trials, assessing clinical outcomes including adverse effects 
… are required.”3 
 
OBJECTIVE 
This study aims to assess the effectiveness and safety of treating pregnant women with iron-deficiency anemia with 
a protocol including intravenous iron compared with a protocol based on oral iron. We hypothesize that treating 
iron-deficiency anemia with intravenous iron is associated with improved maternal and neonatal outcomes 
compared with treatment using oral iron.  
 
STUDY DESIGN AND METHODS 
Overview: We will conduct an open-label, randomized controlled trial to assess the effectiveness and safety of 
treating iron-deficiency anemia in pregnant women with intravenous iron compared with oral iron. We test the 
hypothesis that treating iron-deficiency anemia with intravenous iron is associated with improved maternal and 
neonatal outcomes compared with oral iron. We will use broad inclusion criteria and analyze data using the 
intention-to-treat principle to increase generalizability of the findings.

Screening: 
Pregnant women attending prenatal care will be screened for anemia with repeat CBC at 24 to 28 weeks gestation 
per standard of care. If the initial Hgb at this gestational age is less than 10 mg/dL, they will undergo testing for iron-
deficiency anemia. Iron-deficiency anemia will be defined as anemia with serum ferritin <30ug.  Any pregnant 
woman diagnosed with iron-deficiency anemia who meets all inclusion criteria and no exclusion criteria will be 
eligible for the study (Figure 1). In addition, patients who present for prenatal care after 28 weeks gestation who 
meet all inclusion criteria and no exclusion criteria will be eligible for enrollment if they are diagnosed with iron-
deficiency anemia prior to 34 weeks. 
 
Randomization and Treatment Groups: Patients meeting all inclusion criteria and no exclusion criteria who sign 
informed consent will be enrolled and randomly assigned in a 1:1 ratio using a computer-generated randomization 
sequence to one of two treatment protocols. The two treatment protocols are: 
 
1. Oral Iron Supplement- Oral iron supplementation will occur throughout pregnancy with ferrous sulfate at a dose 
range of 325mg daily to 325mg three times daily. Patients will be instructed to take on an empty stomach or 
with an acidic beverage like orange juice. Patients will continue oral iron supplementation through delivery, 
then refer to their treating physician for further postpartum consumption. Patients will be asked to report any 
side effects of oral iron between 2 – 4 weeks after randomization. Side effects will also be assessed at 
delivery along with reported compliance to the oral iron regimen. 
2. Intravenous Iron- The intravenous iron infusion will occur in the form of 975mg of intravenous iron dextran 
diluted in 250 or 500mL of 0.9% sodium chloride given as a single dose over 1-2 hours. Prior to starting the 
treatment dose, participants will receive a test dose of 0.5mL (25mg) of iron dextran and will be monitored 
by hospital nursing staff for 20-30 minutes (or per local infusion protocol) to ensure there are no transfusion

reactions. This amounts to a cumulative dose of 1000mg IV iron dextran. If iron dextran is unavailable due 
to drug shortage, ferumoxytol will be substituted for this treatment group. Subjects will be given an initial 
510mg IV dose in 100 ml 0.9% sodium chloride over at least 15 minutes. This dose will be followed by a 
second dose of the same concentration 3 to 8 days later. All iron infusions will occur on an obstetric unit 
equipped with continuous monitoring and emergency equipment. Patients will have continuous fetal 
monitoring throughout and at least 30 minutes after the infusion. Patients will be called by research staff 48 
- 72 hours after infusion (second infusion if administering ferumoxytol) to assess for transfusion reactions. 
Women who receive intravenous iron will not receive further oral iron supplementation during pregnancy. 
Postpartum iron supplementation will be left to provider discretion.

STUDY PROCEDURES 
Study patients will have hemoglobin drawn at admission to labor and delivery and on postpartum day one. Neonatal 
hemoglobin and ferritin (and blood gases and/or lactate if performed out of clinical necessity) will be assessed via 
cord blood. Obstetric and neonatal outcomes will be collected by a trained research nurse. Subjects randomized to 
the oral iron group will be asked to report compliance with taking oral iron supplements as well as any side effects 
of taking the oral iron. This self-report will be assessed during their admission to labor and delivery (or via phone 
up to 2 days after discharge). See Figure 2 for schedule of events. Pregnancy, labor and delivery management will 
be per standard obstetric practice.

*If ferumoxytol is administered due to shortage of iron dextran, two infusions will occur in the prenatal period as 
outlined in the randomization section of this document. The post-infusion phone call will occur 48-72 hours after the 
second infusion. 
 
Data analysis: Analyses will follow the intention to treat principle, in which patients will be analyzed in the group to 
which they were randomized whether or not they received the assigned treatment. Continuous variables will be 
compared using the Student’s t-test or Mann Whitney U test, as appropriate. Categorical variables will be compared 
using the χ2 or Fisher’s exact test, as appropriate. We will calculate crude and unadjusted risk estimates and 
differences. We will use multivariable logistic regression to adjust for potential confounders. We will estimate the 
number needed to treat to prevent occurrence of one primary outcome.

Sample size estimation: Based on institutional data the baseline rate of anemia (Hgb<11mg/dl) on admission to 
labor and delivery among women on supplemental oral iron is 38.5%. We estimate that 108 patients will provide 
80% power to detect a 60% or greater relative difference in anemia (38.5% versus ≤15.4%) with intravenous iron 
(alpha=0.05, 2-tailed test). We will recruit 120 patients to account for an anticipated 10% loss to follow-up (Table 
1).  
 
The anticipated effect size of 60% is plausible and conservative. A study by Al et al., the only study that reported 
the outcome of Hgb <11 at the time of delivery, showed an effect size of 88% (4.4% versus 37.8%, RR 0.12, 95% 
CI 0.03, 0.48).4 Based on preliminary data showing that 10 pregnant women received intravenous iron in 6 weeks 
at the Washington University Medical Center, we anticipate that the 124 patients will be recruited within 15 months.

Protections Against Risks 
 
Subjects eligible for recruitment will be approached in a private clinic location. The informed consent process and 
every study visit will occur in a private location. Every follow up interview will be conducted in a private setting, or it 
can be conducted over the phone if the participant would prefer that option. Prior to beginning any phone interviews, 
study staff will ensure that the participant is in a private space. 
The measures outlined below will be employed to monitor and minimize risks.  
i. 
Patients will be counseled about the risks prior to enrollment in the study. 
ii. 
Patient confidentiality will be protected by ensuring only research personnel have access to identifiable 
patient information. Study files will be kept in a secure room. Patient information will be coded and de-
identified prior to analysis and publication of study results. 
iii. 
All iron infusions will occur on an obstetrics unit equipped with emergency protocols and equipment in the 
rare event that a serious adverse event may occur and/or emergent delivery is necessary. All subjects will 
be infused with close monitoring including continuous fetal heart rate tracing. If an infusion reaction occurs 
at the time of infusion, treatment will be administered per the unit care team. 
iv. 
Patients will be contacted by phone by research staff 48 - 72 hours after infusion to assess for transfusion 
reactions. 
v. 
The study team will monitor, document and report to the Institutional Review Board, any adverse events 
among study participants per the plan detailed below.  
 
Reportable Events 
 
The PI at each site will oversee the safety of the study at his/her site. During the study, the investigator or study 
site personnel will be responsible for querying and recording adverse events (AEs) and serious adverse events 
(SAEs), as detailed below.  
 
Types of Reportable Events: 
 
Serious Adverse Events (SAE) 
The site must report all SAEs to the lead site, whether or not they result from study participation, within 24 
hours of learning of the event. A serious adverse event (SAE) is any adverse event occurring within the 
timelines specified in the protocol that results in any of the following outcomes:  
 
Death 
 
Life-threatening situation (subject is at immediate risk of death)  
 
Inpatient hospitalization or prolongation of existing hospitalization 
 
Persistent or significant disability/incapacity 
 
Congenital anomaly/birth defect in the offspring of a subject who received study drug  
 
Important medical events that may not result in death, be immediately life-threatening, or 
require hospitalization, may be considered an SAE when, based upon appropriate medical 
judgment, they may jeopardize the subject and may require medical or surgical intervention 
to prevent one of the outcomes listed in this definition.  
 
Adverse Events (AE)  
An adverse event is any untoward medical occurrence in a clinical investigation subject administered an 
investigational product and which does not necessarily have to have a causal relationship with this 
treatment. An AE can, therefore, be any unfavorable and unintended sign (that could include a clinically 
significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a 
medicinal product, whether or not considered related to the medicinal product.  
 
For this study, abnormal laboratory findings (e.g., clinical chemistry, hematology) or other abnormal 
assessments (e.g., electrocardiogram, X-rays, vital signs) per se are not reported as AEs.  Only the 
Adverse Events of Special Interest (AESI) defined below will be recorded on the CRFs and in the subject’s 
chart.   
 
 


 
IVIDA.Version [6.2] 09.18.2019 
 
9 
 
Adverse Events of Special Interest (AESI) 
Adverse events of particular clinical importance (other than SAEs mentioned above) will be classified as 
adverse events of special interest (AESIs). For this study, AESIs refer to:  
 
 
Mild/moderate reactions:  
o venipuncture complications (blood clot or infection) 
o bowel changes (constipation or diarrhea) 
o chest tightness 
o itching  
o urticaria  
o flushing  
o nausea/vomiting  
o abdominal pain 
o peripheral edema 
o arthralgia  
o new onset back or joint aches  
o mild shortness of breath  
o tachycardia 
o severe hypertension (For infusion group: confined to infusion timeframe only) 
o severe hypotension (For infusion group: confined to infusion timeframe only) 
o neurological changes (syncope, dizziness, headache) (For infusion group: confined to infusion 
timeframe only)  
 
 
Major reactions: 
o anaphylaxis-like reaction (For infusion group: confined to infusion timeframe only) 
o seizures (For infusion group: confined to infusion timeframe only) 
o non-reassuring fetal heart rate tracing (For infusion group: confined to infusion timeframe only) 
 
Assessing and Documenting Reportable Events: 
Subjects will be evaluated for adverse events in the following manner: 
 
Routine monitoring by infusion nurses during the IV iron treatment, with data obtained from the subject’s 
EMR by research staff. 
 
Subjects will be called by research staff 48-72 hours after infusion to assess for transfusion reactions. 
 
Subjects on oral iron therapy will be monitored via their EMR and via contact with research staff as 
outlined in schedule of events 
 
An adverse event report will be generated for each event that will include the following: 
 
Date of event discovery 
 
Severity (mild, moderate, severe, life threatening/disabling, death) 
 
Relationship to treatment 
 
Action taken 
 
Outcome 
 
Expected or not 
 
Date reported  
 
Relevant notes/chart records/supporting documentation to corroborate the event 
 
To whom event was reported (i.e. IRB, lead site, etc.) 
o Non- serious AESIs will be reported to the lead site within 5 days of discovery, 
and to the IRB at renewal.  
 
o SAEs and SAESIs will be reported within 24 hours of discovery to the IRB and the 
lead site.

Relationship of Reportable Events: 
An investigator must make the determination of relationship to the drug for each SAE and/or AESI. The 
relationship to the drug should be assessed using the guidelines presented in the table below.  
 
Relationship to Drug  
Description  
Related  
● Previously known toxicity of agent; or 
● Follows a reasonable temporal sequence from administration of the drug; or  
● Follows a known or expected response pattern to the suspected intervention; or 
● Is confirmed by stopping or reducing the dosage of the drug; and is not explained by any 
other reasonable hypothesis  
Probably related  
• Follows a reasonable temporal sequence from the time of study intervention; and/or  
• Follows a known response pattern to the study drug; and  
• Was unlikely to have been produced by other factors such as the subject’s clinical state, 
therapeutic intervention, or concomitant therapy  
Possibly related  
• Follows a reasonable temporal sequence from the time of study intervention; and/or  
• Follows a known response pattern to the study drug; but  
• Could have been produced by other factors such as the subject’s clinical state, therapeutic 
intervention, or concomitant therapy  
Unlikely related  
• Does not follow a reasonable temporal sequence from the time of study intervention; and  
• Was likely produced by other factors such as the subject’s clinical state, therapeutic 
intervention, or concomitant therapy but for which relationship cannot be definitely ruled out  
Not related  
The adverse event can be determined with certainty to have no relationship to the study drug 
 
 
Severity of Reportable Events:  
The investigator will assess the severity of the AE using the following general guidelines:  
 
Severity 
Description 
Mild: 
An AE that is usually transient, requiring no special treatment, and does not interfere with the 
subject’s daily activities.  
Moderate: 
An AE that introduces a low level of inconvenience or concern to the subject and may interfere 
with daily activities but is usually ameliorated by simple therapeutic measures.  
Severe: 
An AE that interrupts a subject’s usually daily activity and typically requires systemic drug 
therapy or other treatment (a severe AE may not necessarily qualify as an SAE).  
Life-threatening: 
An AE that put the subject at immediate risk of death from the event as it occurred. This does 
not include an event that might have led to death if it had occurred with greater severity.

Outcomes of Reportable Events: 
The investigator will categorize the outcome of each reportable event according to the definitions below:  
Status 
Description 
Resolved: 
The subject recovered from the SAE or AESI.  
Resolved with 
sequelae: 
A condition whereby the consequences of a disease or injury include lingering effects.  
Ongoing: 
At the time of the last assessment, the event is ongoing, with an undetermined outcome. 
Note: Ongoing SAEs and AESIs are not considered resolved as a result of death and no SAE or 
AESI stop date should be recorded for an AESI that is ongoing at the time of death.  
Fatal: 
Adverse Event directly caused death. If a subject dies during participation in the study the 
lead site should be provided with a copy of any post-mortem findings. Note: Death is an 
outcome of an adverse event and not an adverse event in itself. All reports of subject death 
should include an adverse event term (other than “Death”) for the cause of the death.  
 
Other Reportable Events: Promptly Reportable Study Conduct Events 
 
The following events must be reported to the lead site and the IRB within five (5) business 
days of the study team becoming aware of the event. 
 
 
Conduct of research without submitting for IRB review. 
 
Conduct of research prior to receiving IRB notification of final approval. 
 
Initiation of substantive changes (i.e., changes that would affect the subjects’ willingness to 
participate, such as changes to study procedures, risks and/or benefits) to the research 
protocol without prior IRB approval, including changes necessary to eliminate apparent 
immediate hazards to the subject. (note: “IRB-approved protocol” refers to all study 
information, including that contained in the IRB Questionnaires, formal protocol document, 
consents, etc.) 
 
Inclusion of vulnerable subject populations without specific IRB approval. 
 
Conduct of research when IRB approval has expired or been suspended or terminated. 
 
Subject interactions or review of identifiable research data by individuals who have not 
completed appropriate investigator requirements (e.g., COI disclosure and CITI training). 
 
Major protocol deviations/protocol noncompliance that occurred and may, in the opinion of 
the PI, (1)impact subject safety and/or (2) affect the integrity of the data, such as: 
o Dosing errors. 
o Enrolling a subject who does not meet eligibility criteria. 
o Study visits outside of the protocol-specified timeframe or missed study visits. 
 
Failure to obtain consent and/or authorization from subjects, including obtaining consent 
from someone who cannot legally consent for the subject. 
 
Other major deficiencies in informed consent or HIPAA authorization process or 
documentation (e.g., substantive outdated informed consent or HIPAA content, such as 
missing study procedures information, that may affect subjects’ willingness to participate). 
 
 
 
 


 
IVIDA.Version [6.2] 09.18.2019 
 
12
Study Conduct Events Reportable at IRB Renewal: 
Events that do not meet the criteria for prompt reporting should be reported at the time of next study 
renewal to ensure the IRB has a full understanding of the conduct of the research. Events that must be 
reported with the next study renewal submission include: 
 
 
Protocol deviations/protocol noncompliance not previously reported to the IRB. 
 
Minor noncompliance (i.e., likely not serious or continuing), such as: 
o Use of a consent form that is not the most recently-approved version when the content is 
not substantively different from the current IRB approved consent. 
o Use of an unstamped consent form when the content is the same as the current 
IRB approved version. 
o Enrolling more subjects than approved by the IU IRB. 
o Conduct of research by individuals not listed on the study protocol but who have completed 
appropriate investigator requirements. 
o Implementing minor wording changes to IRB study documents without prior IRB approval. 
o Failure to appropriately document consent and/or authorization, if the missing information 
can be clearly corroborated by other documentation (e.g., research notes). 
 
 
Data Monitoring and Quality Control 
Periodic monitoring visits will be made at the investigational site throughout the clinical study to ensure 
that the investigator obligations are fulfilled, and all applicable regulations and guidelines are being 
followed. These visits will ensure that the facilities remain acceptable, the investigational plan is being 
followed, the IRB and local authorities have been notified of approved investigational plan changes as 
required, complete records are being maintained, appropriate and timely reports have been made to the 
sponsor and/or its designees and the IRB, and the investigator is carrying out all agreed upon activities.  
 
An annual report will be generated beginning one year after the first enrollment and will include the 
following: 
 
A list and summary of adverse events;  
 
Whether adverse event rates are consistent with pre-study assumptions;  
 
A summary of recruitment and retention and reason for dropouts;  
 
Whether the study is on track to be completed and accomplish the stated aims. 
 
 
Confidentiality: 
Information about study subjects will be kept confidential and managed according to the requirements of 
the Health Insurance Portability and Accountability Act of 1996 (HIPAA). Those regulations require a signed 
subject authorization informing the subject of the following:  
 
What protected health information (PHI) will be collected from subjects in this study  
 
Who will have access to that information and why  
 
Who will use or disclose that information  
 
The rights of a research subject to revoke their authorization for use of their PHI  
 
In the event that a subject revokes authorization to collect or use PHI, the investigators, by regulation, 
retain the ability to use all information collected prior to the revocation of subject authorization. For 
subjects that have revoked authorization to collect or use PHI, attempts should be made to obtain 
permission to collect at least vital status (i.e. that the subject is alive) at the end of their scheduled study 
period.

DATA COLLECTION AND MANAGEMENT 
 
Case Report Forms 
 
Qualified study staff at the investigational site will perform primary data collection. Electronic case report forms 
(eCRFs) will be used to collect all subject data during the study. The investigator is responsible for the accuracy 
and completeness of all data on the eCRFs. Lead site personnel will review completed eCRFs at regular intervals 
throughout the study.  
 
Information on the eCRFs will be compared to information originally recorded on source documents related to the 
study. Information on the eCRF must match the same information on the source documents or a data query will 
be issued. All eCRFs will be reviewed for completeness, validity, and consistency. Queries will be generated and 
resolved with the sites and all protocol deviations will be recorded on the eCRF.  
 
 
Source Data and Documents 
 
Source data is all information, original records of clinical findings, observations, or other activities in a clinical trial 
necessary for the reconstruction and evaluation of the trial. Source data are contained in source documents. 
Examples of these original documents, and data records include: hospital records, clinical and office charts, 
laboratory notes, memoranda, subjects’ diaries or evaluation checklists, pharmacy dispensing records, recorded 
data from automated instruments, copies or transcriptions certified after verification as being accurate and 
complete, microfiches, photographic negatives, microfilm or magnetic media, x-rays, subject files, and records 
kept at the pharmacy, at the laboratories, and at medico-technical departments involved in the clinical trial. 
 
POTENTIAL BENEFITS AND KNOWLEDGE GAINED 
 
The study is not designed to provide direct benefits to research participants. However, if our hypothesis that 
intravenous iron is superior to the standard oral iron is true, those participants randomized to intravenous iron will 
enjoy the benefits of reduced anemia. More importantly, results from this study have the potential to reduce 
anemia-related complications in pregnant women and their babies. Since the anticipated risk to participants is 
low, the risks-benefit ratio is very favorable.

INDIANA UNIVERSITY INFORMED CONSENT STATEMENT FOR RESEARCH 
 
Intravenous Iron for Iron-Deficiency Anemia in Pregnancy: A Randomized Controlled Trial (IVIDA) 
Principal Investigator: Dr. Methodius Tuuli (317) 944-8182 
IRB #:  1809251633 
 
You are being asked to participate in a research study.  Scientists do research to answer important questions 
which might help change or improve the way we do things in the future. This research study will evaluate the 
effectiveness, safety and benefits of treating iron-deficiency anemia (low levels of iron and red blood cells) 
during pregnancy. Low iron and decreased red blood cells in your body can be found by testing your blood. 
You were selected as a possible participant because your blood was tested as part of your routine prenatal 
care and your results show that you have low levels of iron and red blood cells.    
 
This consent form will give you information about the study to help you decide whether you want to 
participate.  Please read this form and ask any questions you have before agreeing to be in the study. 
 
This study is being conducted by Dr. Methodius Tuuli of Indiana University and in collaboration with 
researchers at Washington University in St. Louis. 
 
Taking part in this study is voluntary. 
You may choose not to take part in the study or may choose to leave the study at any time.  Deciding not to 
participate, or deciding to leave the study later, will not result in any penalty or loss of benefits to which you 
are entitled, and will not affect your relationship with current or future health care providers. 
 
WHY IS THIS STUDY BEING DONE? 
The purpose of this study is to determine the safety and effectiveness of treating pregnant women with iron-
deficiency anemia with either an iron infusion (medication given through an IV) or oral iron supplements 
(pills). Iron dextran is the intravenous (IV) medication being used in this study. Ferrous sulfate is the oral 
medication (pill) being used in this study. Both treatments are currently used in obstetric practice but have not 
been adequately compared. This study will compare these two groups to see if IV iron or oral iron is better for 
the mother and baby after delivery. 
 
HOW MANY PEOPLE WILL TAKE PART? 
If you agree to participate, you will be one of approximately 120 participants taking part in this study at 
Indiana University and Washington University in St. Louis combined. At this site, Indiana University, you will be 
one of approximately 80 participants. Participants will be randomly selected to either the IV iron or oral iron 
group with a goal of having equal numbers of participants in each group. In addition, your baby would be one 
of 120 newborns participating between these two research sites.

WHAT WILL HAPPEN DURING THE STUDY? 
If you agree to be in the study, you will do the following things: 
 
 As part of your standard prenatal care you have been screened for anemia. If you met the threshold for 
anemia in pregnancy, you have also been tested for iron-deficiency anemia. If you have been 
confirmed to have iron-deficiency anemia, you may be eligible to enroll in this study.  
 If eligible, you will be assigned randomly (like flipping a coin) to one of two groups in the study: 
o Intravenous Iron Group 
 You will stop taking any oral iron supplements that were previously ordered and receive 
a one-time infusion of iron dextran. This infusion is made of 1000mg iron dextran that is 
given to you through an IV. The infusion will take place on an obstetric unit of the 
hospital. You will have continuous fetal monitoring throughout the infusion as well as at 
least 30 minutes after the infusion is completed. Fetal monitoring is a way for doctors 
and nurses to watch your baby’s heartrate by placing a stretchy band with an electronic 
disk called a transducer across your abdomen. This transducer is connected to a 
machine and your baby’s heartrate is recorded. Fetal monitoring is commonly done 
during labor. 
 During the iron infusion you will have a “test dose” (a small amount of medication given 
first) to make sure you do not have a reaction to the medication. If after 30 minutes you 
have no reaction, the remaining dose of medication will be given to you through the IV 
over the next 1-2 hours. 
 You will be called by research staff 48-72 hours after the infusion to see how you are 
doing and if you had any reactions or additional questions. You may skip answering any 
question that makes you uncomfortable.  
 There is a small chance that iron dextran will not be available due to a national drug 
shortage. If this happens, ferumoxytol will be substituted. When you are scheduled for 
your infusion, you will be notified by the scheduling unit if you will be receiving 
ferumoxytol instead of iron dextran. Ferumoxytol is another type of IV iron that is 
commonly used to treat iron-deficiency anemia. The dose given for this study will 
include two infusions: 510mg IV followed by another 510mg IV 3-8 days after the first 
infusion. These infusions will be given under the same conditions as described above. 
You will be contacted by research staff 48-72 hours after your second infusion to ask 
you about any side effects. 
o Oral Iron Supplement Group 
 You will start (or continue) taking oral iron supplements. The type of oral iron being 
used in this study is ferrous sulfate 325mg. You will take this pill one, two, or three times 
a day until delivery depending on the dose your doctor prescribes.  
 Note: If your treating doctor feels that you need oral iron supplements after 
delivery, you will follow your doctor’s orders at that time. 


 
 
IVIDA.Tuuli.V1.1 27DEC2018 
 
 
 
 
 
          Page 3 of 8 
 It is recommended that these iron pills be taken either on an empty stomach or with an 
acidic beverage like orange juice. 
 You will be contacted by research staff two times after joining the study. The first 
contact will occur 2-4 weeks after you agree to be in the study; the second contact will 
be at delivery. Research staff may contact you in person at an existing prenatal 
appointment or via phone to see how you are doing and if you had any reactions to the 
iron. You may skip answering any question that makes you uncomfortable.   
 At delivery research staff will also ask you to report how often you were taking your iron 
pills while in the study. 
o Both Treatment Groups 
 Blood and data will be collected from you as part of this study. The blood collected will 
NOT be kept or stored for future use. Data will be collected from your baby.  
 Your blood will be drawn from a vein in your arm on admission to labor and 
delivery as part of your regular care whenever possible. Your blood will also be 
drawn again the day after you deliver your baby as part of your regular care. For 
this study research staff will look at the results of these blood tests in your 
electronic medical record. 
 We will get a blood sample from the discarded umbilical cord after delivery. This 
is called a cord blood sample. We will need approximately 1 teaspoon of cord 
blood. 
 Data will be collected from your electronic medical record and will include: 
demographics, medical history, diagnosis and results of anemia testing, reactions 
to iron infusion or supplements, delivery information, and overall health of you 
and your baby following delivery.  
 Data will be collected from your baby’s electronic medical record and will 
include: gestational age at delivery, birth weight, APGAR scores (rating of your 
baby’s health immediately after delivery), and cord blood lab results. These labs 
will include hemoglobin and ferritin, and may include blood gas and/or umbilical 
artery lactate if these tests were ordered by your treating physician. The study 
team will also record any unforeseen problems with your baby’s health and the 
location of your baby after delivery (with you, NICU, etc.).  
 Your participation in the study will be complete when you are discharged from the hospital and all 
study data has been collected. 
 
Your pregnancy and labor and delivery management will continue to be monitored via standard of care by 
your regular caregiver. 
 
WHAT ARE THE RISKS OF TAKING PART IN THE STUDY? 
While participating in the study, you may experience the risks, side effects, and/or discomforts detailed below.  


 
 
IVIDA.Tuuli.V1.1 27DEC2018 
 
 
 
 
 
          Page 4 of 8 
 
Low Risk 
1. Blood draw: Blood needed for the study will be drawn at the same time as other blood draws ordered 
by your doctor whenever possible to minimize your risk. Reactions to blood draw include:  
 Most common: minor pain at site, bruising 
 Less common: fainting or dizziness 
 Rare: blood clots or infection where the needle enters the skin 
*Note: There is no risk associated with collecting cord blood since the umbilical cord will be separated 
from you and your baby after delivery. 
2. Breach of confidentiality: One risk of participating in this study is that confidential information about 
you may be accidentally disclosed. We will make the best efforts to keep the information about you 
secure. Please see the section in this consent titled HOW WILL MY INFORMATION BE PROTECTED? for 
more information. 
 
 
Moderate/High Risk 
1. Oral iron supplement: Reactions to oral ferrous sulfate include: 
 Most common: constipation, nausea/vomiting, stomach discomfort or upset, dark stools 
 Less common: diarrhea, heartburn, urine discoloration 
 
2. Iron infusion: This infusion will take place on an obstetric unit which is equipped with continuous fetal 
monitoring and emergency equipment for mother and baby if needed. This monitoring will enable your 
medical team to more readily notice early signs of reactions to iron dextran or ferumoxytol infusion 
which include: 
 Most common: discomfort and/or bruising at the site where the IV is placed 
 Less common: chest tightness, itching, urticaria (hives), flushing, nausea/vomiting, arthralgia (joint 
pain), back or joint aches, shortness of breath, tachycardia (fast heart rate), bradycardia (slow heart 
rate), cardiac arrhythmia (changes in heart rhythm), hypertension or hypotension (high or low 
blood pressure), shock (very low blood pressure), abdominal pain, diarrhea, peripheral edema 
(swelling in limbs), headache, dizziness, syncope/loss of consciousness (fainting), chills, or 
numbness.  
o These reactions could be delayed by 1 or 2 days after your infusion. 
 Rare: Anaphylaxis (severe allergic reaction), seizures, or non-reassuring fetal status (changes in 
fetal heart rate). Any of these reactions if severe could lead to maternal or fetal death. 
 
Other Risk 
You will be assigned to a treatment group by chance, and the treatment you receive may prove to be less 
effective or to have more side effects than the other study treatment or other available treatments. There is a 
possibility that there are other risks that may not be known at this time.

WHAT ARE THE POTENTIAL BENEFITS OF TAKING PART IN THE STUDY? 
The study is not designed to provide direct benefits to you. However, study doctors have reason to believe 
intravenous iron may be superior to oral iron. Therefore, if you are placed into the infusion group, you may 
experience the benefits of reduced anemia. Additionally, results from this study have the potential to reduce 
anemia-related complications in pregnant women and their babies. By participating you are helping to gather 
these results.  
 
WHAT ARE THE OTHER TREATMENT OPTIONS? 
Treatment for iron-deficiency anemia in pregnancy is typically treated with oral iron or with IV iron, which are 
the two treatments being compared in this study. You do not have to be in this study to receive either of these 
treatments from your doctor. If you choose not to participate, your decision will not affect your clinical care. 
 
HOW WILL MY INFORMATION BE PROTECTED? 
Your privacy is very important to us. The researchers are taking many steps to protect the privacy of you and 
your baby. If you agree to take part in the study, a study ID number will be assigned to you and your baby. This 
number will be used to identify medical information kept by the study. Any records linking your name to the 
study ID will be stored in a locked (password protected) file.  
 
All copies of your medical records and the links between your name and the study ID will be destroyed within 
fifteen years of the end of the study. After that time, your samples and information from your interviews and 
medical records collected for the study will be linked together with your study ID number only. Even though 
the information will still be used for research, it will no longer be easy to link it to you. 
 
Efforts will be made to keep your personal information confidential.  We cannot guarantee absolute 
confidentiality.  Your personal information may be disclosed if required by law.  No information which could 
identify you will be shared in publications about this study. Your identity will be held in confidence on 
databases in which results may be stored. 
 
Organizations that may inspect and/or copy your research records for quality assurance and data analysis 
include groups such as the study investigator and his/her research associates, the Indiana University 
Institutional Review Board or its designees, and (as allowed by law) state or federal agencies, specifically the 
Office for Human Research Protections (OHRP), who may need to access your medical and/or research 
records. 
 
A description of this clinical trial will be available on www.ClinicalTrials.gov, as required by U.S. law.  This 
website will not include information that can identify you.  At most, the website will include a summary of the 
results.  You can search this website at any time.

          Page 6 of 8 
WILL I BE PAID FOR PARTICIPATION?  
You will be given a $20 gift card at your prenatal visit when you agree to be in the study. You will receive 
another $20 gift card upon collection of your blood, cord blood, and data after your delivery. This gift card will 
be given to you at delivery if data collection is complete. If additional data is still needed at the time of your 
discharge, the gift card will be mailed to you.  
 
WILL IT COST ME ANYTHING TO PARTICIPATE?  
This study compares two already-accepted ways of treating iron deficiency anemia in pregnancy.  Both ways 
are standard of care that could be prescribed during your pregnancy. Taking part in this study may lead to 
added costs to you or your insurance company. You or your insurance company will be responsible for the 
costs of either of these treatment options, including the cost of the medication and facility fees. This will be 
billed the same as if you were not in the study; it will be billed as part of your regular medical expenses. 
 
WHO WILL PAY FOR MY TREATMENT IF I AM INJURED? 
In the event of physical injury resulting from your participation in this study, necessary medical treatment will 
be provided to you and billed as part of your medical expenses.  Costs not covered by your health care insurer 
will be your responsibility.  Also, it is your responsibility to determine the extent of your health care coverage.  
There is no program in place for other monetary compensation for such injuries.  However, you are not giving 
up any legal rights or benefits to which you are otherwise entitled.   
 
WHO SHOULD I CALL WITH QUESTIONS OR PROBLEMS? 
For questions about the study or a research-related injury, contact the researcher, Dr. Methodius Tuuli, at 
317-944-8182. After business hours, please call the on-call OBGYN physician at 317-880-5729.   
 
In the event of an emergency, you may call 911 or go to the Emergency Department.
