Conditions: Autism Spectrum Disorder
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 72
Healthy volunteers: no

Brief summary:
The purpose of this study is to examine how fatty acid supplementation alters biological signatures in children with ASD

Detailed description:
Children with Autism Spectrum Disorder (ASD) suffer from both mental and physical symptoms that affect their quality of life and severely disrupt family well-being. Fatty acid supplements are natural products with anti-inflammatory properties often used for treatment of ASD symptoms, but their efficacy remains unproven. The objective of the proposed protocol is to quantify the impact of Omega 3-6 on pre-specified biological signatures. The hypotheses were formulated based on data from the investigators previous studies and other published data which suggest that the inflammatory markers, IL-1β, IL-2, and IFNγ are consistently elevated in children with ASD and decreases in these markers correlate with ASD symptom improvement. The investigators long-term goal is to identify effective treatments for ASD.

Key Information About This Study  
 
The following is a short summary of this study to help you decide whether or not to participate.  More 
detailed information follows later in this form. 
 
The purpose of this study is to find out if a fatty acid nutritional supplement oil is an effective treatment 
for autism spectrum disorder symptoms.  
 
Caregivers will be asked to give their child a fatty acid nutritional supplement oil or placebo oil every 
day (in the morning and evening) for 3 months. 
Your child will have blood drawn 3 times during participation. 
Caregivers will be asked to complete some brief questionnaires. 
Caregivers will complete a study diary to show if child took study treatment each day.  
 
There will be 3 visits over 3 months at the main campus of Nationwide Children’s Hospital.  
First visit: 2-2.5 hours, second visit: 1 hour, third visit: 1.5 hours 
We will call you five times within the 3 months of participation. One call will last longer (20-25 minutes) 
than the others. 
See a more detailed discussion later in this form. 
 
The main risks of the study are bleeding and bruising at the site where the blood is drawn, allergic 
reaction to nutritional supplement oil or placebo oil, and mild diarrhea, gas or other intestinal related 
symptoms associated with nutritional supplement oil or placebo oil. 
 
You and your child may not benefit from being in this study.  We hope that the information learned will 
help others in the future who have an autism spectrum disorder diagnosis.

1) INTRODUCTION 
This is a research study that is interested in learning about how a nutritional supplement oil may 
help children with Autism Spectrum Disorder (ASD). Dr. Sarah Keim and Dr. Lynette Rogers are 
working on this study with doctors from the Developmental and Behavioral Pediatrics Department at 
Nationwide Children’s Hospital. We invite you to participate in this research study because your 
child was recently diagnosed with ASD. 
 
Your participation in this study is voluntary. Please learn enough about this research study and its 
risks and benefits to decide if you agree to participate. We will explain the study to you and give you 
a chance to ask questions about anything you do not understand. This process is called “informed 
consent.” It is up to you to choose if you want to be in this study. You may decline to participate in 
this study or quit this study at any time, and standard medical care will still be available here or at 
the doctor of your choice without a penalty or loss of benefits to you and your child. 
 
Before agreeing to be in this research study, it is important that you read and understand the study 
information in this consent form. By signing this consent form, you agree to be in this study. If you 
choose to participate, you will be given a signed and dated copy of the consent form. 
 
2) WHY ARE WE DOING THIS RESEARCH STUDY? 
Although at least 1 in 68 U.S. children has been diagnosed with ASD, no approved medications 
exist to treat the core symptoms. 
 
Some studies have shown that children with ASD who take a nutritional supplement oil that has 
long chain polyunsaturated fatty acids show less hyperactivity and act out less than children who 
took a placebo oil. A placebo is made to look, smell, and taste like the fatty acid supplement, but does 
not contain the same ingredients. Fatty acids are naturally found in foods like fish. We think fatty acid 
nutritional supplements might have these benefits because they reduce inflammation in the body. 
Inflammation seems to be common in people with ASD. So, this study will look at how fatty acid 
nutritional supplement oil may reduce inflammation in the body.  
 
3) WHERE WILL THE STUDY BE DONE AND HOW MANY FAMILIES WILL TAKE PART?  
This study will be done at Nationwide Children’s Hospital. We hope to enroll about 66 families in this 
study.   
 
4) WHAT WILL HAPPEN DURING THE STUDY AND HOW LONG WILL IT LAST? 
This study will last for 90 days, about 3 months. 
 
During the study, we ask that you give your child a nutritional supplement oil or placebo oil every day, 
twice a day, during the study. We also ask that you come to Nationwide Children’s Hospital 3 times. 
Visit 1 is today. Visit 2 will be 45 days later and visit 3 will be 45 days after that. If you have a visit 
scheduled already in any of the Nationwide Children’s Hospital clinics, we will try to make the study 
visit the same day to make it convenient. The study visits last anywhere from 1 to about 1.5 hours.  
 
What we ask you to do: 
• 
During the study visits, we will ask you to answer questions about your child’s diet and your 
family. You have the option of skipping any question you do not want to answer. We will ask 
you to provide us with updated contact information. We will not share this information with 
anyone outside the research team and we will only contact you about the study.  
 
• 
During the first and last in-person visits, trained research staff will measure your child’s height 
and weight. 
 


 
 
 
 
 
 
 
17Dec2018 
                       Page 4 of 11 
 
• 
During each in-person visit, a 3mL (about half a teaspoon) blood sample will be drawn by an 
experienced and trained Nationwide Children’s Hospital employee. The blood drawn during 
each visit will be used to see how much of the oil your child is taking and how the body is 
responding to the oil.  
 
• 
At the first study visit, you will be given bottles of an oil to take home with you. We will ask you 
to give your child the oil each day. We will provide a paper diary and instructions for you to 
record that your child took the oil. 
  
• 
We will check in with you a total of 5 times to see how the study is going for you. One of these 
phone calls will request a more detailed update than the others. We will call this phone call our 
“e-visit.” We will provide you with our phone number and e-mail address for you to contact us 
with any concerns or questions. During the follow up calls, study staff will request photos of 
complete study diary pages on occasion. These photos can be texted or emailed on the day of 
the follow up call.  
 
To check to see if the fatty acids help children with ASD and to see what the best dose is, we need 
different groups of families. To determine which group each family is in, this study is randomized.  The 
word “randomized” means that each family will be picked by chance, like tossing a coin or drawing 
straws, to receive a low, medium, or higher dose of the fatty acid supplement oil or placebo oil. By 
randomizing families into one of the groups, we can check in a fair way to see if the nutritional 
supplement helps children with ASD. 
 
One group will receive the nutritional supplement which is a liquid that contains oil from fish and oil 
from a plant called borage. The fatty acids in this liquid are naturally occurring and are found in 
breast milk and foods like chicken, fish, and cooking oils.  The other group will receive a placebo 
liquid which contains canola oil, a common cooking oil. The nutritional supplement and placebo 
contain a small amount of lemon to make them taste good. There are no known benefits of the 
placebo oil.  Both the nutritional supplement oil and placebo oil look, smell, and taste the same.   
 
This study is blinded. Blinded means you and all the staff involved in the study will not know who is 
receiving the nutritional supplement oil or the placebo oil. However, in the case of a medical 
emergency, there is a way for the study staff to quickly find out which one a child is receiving. 
 
5) WHAT ARE THE RISKS OF BEING IN THIS STUDY?  
We believe that there is very little chance that bad things will happen as a result of being in this study. 
It is possible that you could feel upset when answering questions about your and your child’s well-
being and health, but it is more likely that you find the questions or feedback process a little boring. If 
you do find any of the questions upsetting or don’t want to answer a question, you don’t have to.  
 
Although the nutritional supplement oil and placebo oil used in this study are available to buy over-
the-counter in local stores, all nutritional supplements or oils may cause side effects or allergic 
reactions. There is no way to predict whether your child will have any side effects.  
 
Common side effects may include mild cases of diarrhea, gas or other intestinal related symptoms.  
Allergic reactions can happen with any nutritional supplement. Symptoms of an allergic reaction can 
include rash, itching, hives, headache, stomach discomfort, or difficulty breathing.  Because of this, 
children with a fish, canola, or borage seed allergy are not eligible to participate.  Allergic reactions 
can be severe and possibly life threatening. Severe allergic reactions are a rare possibility.  
 
An experienced employee will draw a small amount of blood and will work to make this as painless as 
possible for your child. The physical risks of drawing blood by placing a needle in a vein may cause 


 
 
 
 
 
 
 
17Dec2018 
                       Page 5 of 11 
 
pain, lightheadedness, bleeding, bruising, or swelling at the puncture site. Infection is a rare 
possibility. 
 
If any of the symptoms listed above are severe, you must get medical help right away.  If you are 
worried about anything while in this study, please call the Principal Investigator, Study Doctor, or 
Study Coordinator.  The contact information is listed on Section 16. 
 
Although we will take every precaution, there is a small chance of loss of confidentiality of your study 
information.  
 
There may be other risks of being in this research study, which are not known at this time.  
 
6) ARE THERE BENEFITS TO TAKING PART IN THIS STUDY?   
Although there may be no direct benefit to you from being in this study, we might learn something 
that could help other children with ASD and their families in the future.  
 
7) WHAT OTHER OPTIONS ARE THERE?   
Your participation in this study is voluntary. It is not necessary to participate in this study in order for 
you to get care for your child’s condition. 
 
8) WILL THERE BE ANY COSTS TO ME? 
It will not cost you anything to be in this study. We will not bill you or your insurance company for the 
study. For your time and inconvenience, you will be compensated $75 at the end of each of the 3 in-
person study visits. In addition, we will give you $2 every time you return a study diary (up to $14 total 
if all diaries are returned) to thank you for your time and effort.  We will pay for your parking in the 
Children’s Hospital Parking Garage during your study visits. We also will give your child a book or toy 
to take home at the completion of each study visit. If you complete all study visits and the e-visit 
phone call, you will be compensated an additional $20 at the end of the final visit.  
 
In regards to your compensation, Nationwide Children’s Hospital is now using a service called 
ClinCard® by the company Greenphire to manage payments for study participation. You will no 
longer be receiving compensation in cash, check, or by gift card. 
 
You will be issued a ClinCard® debit card specially designed for clinical research. When each study 
visit is completed, funds will be approved and automatically loaded onto your card. The funds will 
be available immediately after being loaded, but could take up to 1-2 business days. These funds 
can be used at your discretion. You will be issued one card for the duration of your participation.  If 
your card is lost or stolen, please call the study coordinator for a replacement card. 
 
Your name, subject number, address, email address, cell phone number and social security number 
will be collected by Nationwide Children’s Hospital in order to issue the debit cards. Debit cards are 
managed by Greenphire Inc.  All information is stored in a secure fashion.  Your information will not 
be shared with any third parties and will be kept completely confidential. 
 
If you receive $600 or more in a calendar year from participating in research studies, you will be 
issued a 1099 IRS Form to file with your income taxes. 
 
 
9) WHAT HAPPENS IF BEING IN THIS STUDY CAUSES INJURIES? 
We believe that there is very little chance that injuries will happen as a result of being in this study.  
 


 
 
 
 
 
 
 
17Dec2018 
                       Page 6 of 11 
 
If your child is hurt by the nutritional supplement oil or placebo oil or the procedures that are part of 
the study, you should seek medical treatment for the injuries and tell the Principal Investigator or 
Study Doctor as soon as possible. See the phone number listed in Section 15 of this form.  If it is an 
emergency, call 911 or go to the nearest emergency department. 
 
In most cases, this care will be billed to your health insurance company or whoever usually pays for 
your health care at the usual charges, but some insurance companies will not pay for care related to a 
study. If the care is provided at Nationwide Children's Hospital, we make no commitment to pay for 
the medical care provided to you. No funds have been set aside to compensate you in the event of 
injury.  If no one else pays for your care, you may have to pay for the cost of this care. This does not 
mean that you give up any of your legal rights to seek compensation for your injuries.  
 
 
10) WHAT WILL HAPPEN IF NEW INFORMATION IS FOUND OUT ABOUT THE DRUG OR 
TREATMENT?   
If new information is found out during this study that might change your mind about participating or 
might affect your child’s health, a study staff member will discuss it with you as soon as possible. 
 
11) WHAT HAPPENS IF I DO NOT FINISH THIS STUDY? 
It is your choice to be in this study. You may decide to stop being in the study at any time. If you 
decide to stop being in this study, you must call the Principal Investigator or the Study Coordinator.  
If you stop being in the study, there will not be a penalty or loss of benefits to which you are 
otherwise entitled. The Principal Investigator will talk to you about any medical issues regarding 
stopping. 
 
If at any time the Principal Investigator or Study Doctor believes participating in this study is not the 
best choice of care, the study may be stopped and other care prescribed. If the study instructions are 
not followed, participation in the study also may be stopped.  If unexpected medical problems come 
up, study staff may decide to stop your participation in the study. 
 
 
12) OTHER IMPORTANT INFORMATION 
It is important that health care providers know about all medicines that your child is taking. This 
includes the nutritional supplement oil being tested in this research study. Because of this, we may 
inform your primary care doctor (if you have one) that your child is participating in this study and 
document his/her participation in this study in your Nationwide Children’s Hospital medical record. 
This is done so extra care can be taken in prescribing other medicines and looking at any 
unexplained symptoms that may occur.

13) HOW WILL MY STUDY INFORMATION BE KEPT PRIVATE?   
Information collected for this study may include information that can identify you. This is called 
“protected health information” or PHI. By agreeing to be in this study, you are giving permission to 
Dr. Sarah Keim and Dr. Lynette Rogers and their study staff to collect, use, and disclose your PHI 
for this research study unless otherwise allowed by applicable laws. Every effort will be made to 
keep your PHI private. Your PHI will be removed or coded (de-identified) as much as possible to 
protect your privacy.   Information collected is the property of the Principal Investigators. In the 
event of any publication regarding this study, your identity will not be revealed. 
 
If you have a bad outcome or adverse event from being in this study, the Principal Investigators and 
staff or other health care providers may need to look at your entire medical record. 
 
The PHI collected or created under this research study will be used or disclosed as needed until the 
end of the study. The records of this study will be kept for an indefinite period of time.   
 
PHI that may be used or disclosed may include demographic information such as names, 
addresses, telephone numbers; medical diagnoses, dates such as admission/discharge and 
birthdate; and identifying numbers such as medical records number. 
 
Some of the people or companies that may be authorized to use, disclose, and receive PHI 
collected or created by this research study include:  
• 
The Principal Investigators, Study Doctor, and the study staff 
• 
Representatives of the Office for Human Research Protections, the federal government 
office that oversees human subject research

14) STORED SAMPLES  
Sometimes, a small amount of blood may be leftover from the study and stored for research at a later 
time, perhaps even years from now. 
 
With your permission, we would like to store any leftover study samples and information related to 
such samples (diagnosis, age at diagnosis, etc.) for research that may be performed in the future.  
Any unused samples will be stored for an indefinite amount of time.  Information related to the 
samples may or may not include personal identifiers, such as your name, address, etc.  There could 
be widespread sharing of these samples and associated information, but an Institutional Review 
Board, which protects the rights, welfare, and safety of human research subjects, will review and 
approve each new project.   
 
Use of your samples for future research may help researchers learn more about how to prevent, find, 
and treat various diseases and conditions, even diseases and conditions that are different from yours.  
Genetic material (such as DNA and RNA) may be removed from the stored samples and used for 
genetic testing, which could uncover information about your inherited traits.   
 
Using your samples for future research will probably not help you.  You will not be told the results of 
any future research.  Your doctor will also not be told the results of any future research.   
 
Your samples and information will be used only for research and will not be sold.  There is a 
possibility that future research may lead to development of products that will be sold to the public.  If 
this happens, there is no plan to share any financial gain with you.   
 
The results from this future research may be published but your identity will not be revealed.   
 
If you decide at any time that you do not want your samples or related information stored for future 
research, you must make this request in writing to the Principal Investigator. 
 
Once we receive your written request, we will destroy your samples and related information.  
However, once your samples and related information have been de-identified, we will not be able to 
destroy them because we will not be able to link your samples or information back to you.  Also, if 


 
 
 
 
 
 
 
17Dec2018 
                       Page 9 of 11 
 
we have already shared your samples or information with another individual or entity, we will not be 
able to destroy any of the samples or information that are no longer in our possession. 
 
Nationwide Children’s Hospital retains the right to cease storage of the samples or related 
information at any time and destroy the samples or information without sending notice to you or 
obtaining your consent. 
 
You do not have to agree to use of your samples or related information for future research in order 
to be in this study, and your decision will not affect the care you receive from the study doctors or 
Nationwide Children’s Hospital. 
 
I agree to allow my samples and related information to be stored and used for future research as 
described above: (initial your choice)

PROTOCOL SUMMARY 
 
Title: 
Fatty acid supplements alter biological signatures in children with Autism Spectrum  
Disorder 
Background: 
Fatty acid supplements are among the most popular complementary products consumed by 
children with Autism Spectrum Disorder (ASD). Their use is driven by anecdotal evidence of 
benefit and a few small RCTs that demonstrated improvements in some externalizing behaviors 
in this population.1-3 Overall, there remains scant evidence for efficacy in treating the core 
symptoms of ASD like social-communication deficits and restricted and repetitive behaviors. 
Furthermore, very little is known about the biological signatures that are affected. Over-the-
counter (OTC) fatty acid supplements are plentiful and consist of varying percentages of 
gamma-linoleic acid (GLA, an omega-6 fatty acid), eicosapentaenoic acid (EPA, an omega-3), 
and docosahexaenoic acid (DHA, omega-3) and often include vitamins or plant extracts as well. 
Existing RCTs have tested varying combinations of fatty acids with conflicting results that likely 
stem from this variation. Because there are no approved medications to treat the core 
symptoms of ASD, well-intentioned parents are reaching for any product that promises 
improvement in their child, but they are giving these supplements without guidance as to their 
function, mechanism of action, or whether they are harmful or helpful in symptom management. 
 
For the proposed project, we will focus on preschool and early school aged children because of 
the extensive literature indicating that a wide range of ASD therapies are maximally beneficial if 
they begin as early as in life as possible after diagnosis. This may be because neuroplasticity 
decreases significantly as children age, accompanied by the fact that DHA accretion in the 
developing brain displays a corresponding decline in rate with age.4 Along similar lines, it has 
recently been reported that fatty acid bioavailability and treatment effects in children may 
depend partially on body size (smaller children exhibit higher fatty acid levels for a given dose 
than larger children). Many pediatric medications are dosed based on body weight; however, 
this concept has been virtually never applied to fatty acid supplementation. Aside from 
considerations about body size, only rarely are fatty acid supplements subjected to dose-
ranging trials where a variety of doses are examined simultaneously to identify the most 
efficacious and tolerable. At most, a few studies have tested 2 doses vs placebo. These gaps in 
the literature represent a barrier to informing patients and clinicians about optimal dosing for a 
given child, with the end result that some children likely take a dose too small to benefit. 
 
Population: 
A randomized, fully-blind, placebo-controlled trial of 66 children ages 2-6 years with recently-
diagnosed ASD. The trial will involve 90 days of treatment with one of 3 different doses (25 mg, 
50 mg, or 75 mg twice per day, using child weight) of Omega 3-6 or (equal volume) placebo 
and will include 4 study visits. 
 
Study 
Objectives: 
1) Optimize safety and bioavailability of Omega 3-6 in a unique population of children with ASD; 
2) Evaluate the effect of Omega 3-6 supplementation on biological signatures of inflammation.

2 BACKGROUND INFORMATION AND SCIENTIFIC RATIONALE 
2.1 Introduction  
Although at least 1 in 68 U.S. children has been diagnosed with Autism Spectrum Disorder (ASD), 
no approved medications exist to treat the core symptoms. Atypical antipsychotics are commonly 
prescribed for irritability with ASD, but the side effects are significant, common, and of particular 
concern for very young children.5 Behavioral interventions can offer families approaches to live with 
the atypical behaviors and social deficits of ASD, but they are not cures. Because of the dearth of 
effective treatments, between 52% and 95% of families commonly try complementary therapies 
including fatty acid supplements, based largely on anecdotal evidence. To date, the results of 
efficacy trials testing fatty acid supplementation for ASD are mixed for several reasons including 
variation in the particular combination and dose of fatty acids tested and study design shortcomings 
including lack of blinding or placebo control. Another major reason for the lack of clarity is the very 
limited extent to which studies have evaluated potential biological signatures of interest in order to 
shed light on the pathways through which fatty acids may exert their effect. This proposal will 
determine a primary pathway through which Omega 3-6 supplementation can benefit ASD 
symptoms, by studying a leading candidate set of biological signatures and addressing related gaps 
in the literature that preclude successful efficacy trials. 
Fatty acid supplements are among the most popular complementary products consumed by 
children with ASD, driven by anecdotal evidence of benefit and a few small RCTs that demonstrated 
improvements in externalizing behaviors. Because no approved drugs exist to treat the core 
symptoms of ASD, well-intentioned parents are reaching for any product that may help their child. 
The implications are that fatty acid supplements are given to children without any evidence base as 
to their function, mechanism of action, or benefits versus harms. Overall, there remains scant 
evidence for efficacy of fatty acids in treating core ASD symptoms from well-designed and 
adequately-powered RCTs, and very little is known about the mechanism(s) of action. Over-the-
counter (OTC) fatty acid supplements are plentiful and consist of varying percentages of oleic acid 
(n-9), gamma-linolenic acid (GLA, n-6), eicosapentaenoic acid (EPA), and/or docosahexaenoic acid 
(DHA) and often include vitamins or other plant extracts. Existing RCTs have tested varying 
combinations and doses of fatty acids, and conflicting results likely stem from this variation. Recent 
evidence from our group and others suggest a combination of fish and borage oils providing 
supplementation of DHA, EPA and GLA (“Omega 3-6”) is particularly promising compared to other 
formulations. Based on these foundations, a critical need exists to evaluate Omega 3-6 for optimal 
dosing and changes in a biological signature that are related to ASD symptoms, before a rigorous, 
full-scale efficacy trial can be launched.  
 
Our long-term goal is to identify effective treatments for ASD.  The objective of the study is to 
optimize safety and bioavailability of Omega 3-6 in a unique population of children with ASD and 
evaluate the effect of Omega 3-6 supplementation on biological signatures of inflammation. A 
later study to be described in a future protocol will relate these changes to core ASD symptoms. 
Our overall hypothesis for the line of research is that Omega 3-6 will alter biological signatures 
related to inflammation in a manner that correlates to ASD-related behaviors. Our hypotheses 
were formulated based on data from our Preemie Tots study and other published data which 
suggest that the inflammatory markers, IL-1β, IL-2, and IFNγ are consistently elevated in 
children with ASD and decreases in these markers correlate with ASD symptom improvement. 
The rationale for the proposed research is that its successful completion will provide the 
infrastructure and endpoints necessary to support a future efficacy trial to give parents and 
clinicians unequivocal evidence for fatty acid supplementation for ASD.

2.2 Biological Pathways and Mechanisms  
Fatty acids (FA) have diverse and complex biological functions. Long chain polyunsaturated fatty 
acids of the omega-3 series have been extensively studied and demonstrate anti-inflammatory 
properties affecting multiple pathways. The omega-3 DHA comes from fatty fish or algal sources, is 
the primary neuro-active fatty acid in the brain, and is a key player in neurotransmitter function, 
synaptogenesis, gene expression, membrane fluidity, neurogenesis, neuroplasticity, and anti-
inflammation.6-11 EPA, also from fish oil, is often included in omega-3 fatty acid supplements and 
has triglyceride lowering properties and anti-inflammatory properties similar to DHA. GLA is a 
shorter-chain fatty acid of the omega-6 series derived from plant sources including borage and 
evening primrose. GLA is a precursor to fatty acids such as arachidonic acid (AA) which is essential 
for lipid signaling and hormone synthesis. Biologically available GLA is quickly converted to dihomo-
γ-linolenic acid (DGLA), which now has been shown to have substantial anti-inflammatory 
properties unique among longer chain n-6 fatty acids.12 As omega-3 and omega-6 fatty acids share 
common desaturation and elongation enzymatic pathways, combinations of these fatty acids can 
effectively compete for these enzymes creating a physiologic balance rather than a shift toward one 
pathway or the other. The mechanisms associated with the anti-inflammatory effects of long chain 
fatty acids are still not completely understood but include direct binding to g-coupled protein 
receptor 120 (GCPR120) or peroxisome proliferator-activated receptor gamma (PPARγ) to inhibit 
MAPK or NFkB activation, production of alternative lipid products such as resolvins and protectins, 
and changes in membrane composition that alters ligand binding to cytokine or toll-like receptors.   
Children with ASD have been shown to exhibit altered fatty acid metabolism; several investigations 
have shown decreased levels of DHA, EPA, and AA in these children. The reason for these 
decreases is not completely clear but may be due to a combination of diet differences, altered 
absorption, defects in fatty acid synthesis because of polymorphisms in fatty acid desaturase genes 
(FADS2) or other metabolic alterations.13-15 Since all of these FAs contribute to important biological 
functions, influence anti-inflammatory pathways, and enhance anti-inflammatory mechanisms, we 
speculate that decreases or deficiencies in these FAs directly contribute to the increased 
inflammation observed in ASD patients. 
2.3 Advantages of Fatty Acid Combination Therapies 
DHA has been the most widely investigated fatty acid for treatment of mental disorders and has 
demonstrated efficacy in patients with depressive or schizophrenic symptoms. In addition, DHA 
reduces the risk of mild or significant mental delay in extremely preterm infants.16 However, DHA 
alone appears to exhibit little or no benefit in treating aberrant behavioral symptoms.17 Adding EPA 
to DHA (“EPA+DHA,” usually in the form of fish oil) has been evaluated in 4 RCTs for benefits to 
individuals with ASD. One small trial (n=13) showed benefit to language and maladaptive 
behaviors,3 2 other small trials reported benefits limited to hyperactivity,2,18 and the most recent trial 
reported worsening externalizing behaviors.19 EPA+DHA has been shown to be moderately 
efficacious in reducing symptoms of Attention Deficit Hyperactivity Disorder (ADHD) in large RCTs 
(meta-analysis standardized mean difference=0.31, 95% CI: 0.16, 0.47).20 The combination of 
Omega 3-6 holds significant promise to be more efficacious than EPA+DHA for ASD for several 
reasons. Direct comparison of the evidence for Omega 3-6 vs EPA+DHA for treating ADHD in a 
recent meta-analysis reported larger effect sizes and more consistent benefit for omega 3-6 than for 
EPA+DHA (standard difference in means -0.31 favoring omega 3-6-9 (CI: -0.46, -0.16)).21 Among 
the largest of these studies, Richardson et al. found a >0.5-standard deviation reduction in global 
Conners’ Teacher Rating Scales scores among children randomized to Omega 3-6 for 3 months 
compared to placebo, and Sinn et al. found medium-strong effects of supplementation on parent 
ratings of ADHD symptoms.22,23 However, only 2 placebo-controlled RCTs have tested Omega 3-6 
formulations for developmental or behavioral outcomes other than ADHD: one study demonstrated 
benefits for school-age children with Developmental Coordination Disorder on reading and spelling

achievement and across multiple behavioral domains, and our Preemie Tots study demonstrated 
reduced autistic behaviors, compared to a placebo.22 
2.4 Inflammation in Patients with ASD 
ASD is characterized by pervasive deficits in social communication accompanied by stereotypic 
behaviors. The severity of these symptoms varies widely in ASD and can be accompanied by 
significant cognitive impairment. The etiology of ASD remains unclear, but it has both genetic and 
environmental contributors which impact inflammatory pathways. Inflammation has been well 
characterized in patients with ASD with increases in inflammatory cytokines and chemokines both in 
the circulation and CSF.  Interleukin (IL)-1β is an acute response cytokine produced by immune 
cells and acts through targeting cognate receptors present on the cell membrane in tissues. 24 IL-1β 
can cross the blood-brain–barrier, inducing increased permeability or be produced by astrocytes 
and microglia in the brain.  Increases in IL-1β in neurological tissues, causes increased exocytosis 
of several neurotransmitters, resulting in increased excitability, anxiety, and activation of the 
HPA.25,26 Interleukin (IL)-2 has been extensively studied in the context of brain development and T-
cell fate.27 IL-2 acts in a trophic manner during development and loss of IL-2 causes deficits in 
learning and memory processing in animal studies. Alternatively, IL-2 regulates immunological 
homeostasis, self-tolerance and T cell development and function implying dysregulation may play a 
significant role in neurological auto-immune diseases.24,27 Interferon gamma (IFNγ) is produced 
primarily by epithelial cells and is the acute phase cytokine produced in response to viral infections. 
Besides its effects in mediating viral immunity, IFNγ also modulates adaptive immunity through 
skewing T cell responses to an inflammatory Th1 phenotype.28-30 A recent meta-analyses of clinical 
studies in ASD patients revealed that IL-1β and IFNγ were both elevated in virtually every study 
included (IL-2 was not evaluated) and we observed similar increases in IL-1β and IFNγ in our 
Preemie Tots study.31  Of most importance, we observed lower levels of IL-1β, IFNγ, and IL-2 in the 
children that were supplemented with the Omega 3-6 formulation.  
2.5 Evidence for the Need for Early Intervention and Tailored Dosing 
For the proposed project, we will focus on young children ages 2 to 6 because of the extensive 
literature indicating that a wide range of ASD therapies are maximally beneficial if they begin as 
early in life as possible after diagnosis. This may be because neuroplasticity decreases significantly 
as children age, accompanied by the fact that DHA accretion in the developing brain displays a 
corresponding decline in rate with age.4  Along similar lines, it has recently been reported that fatty 
acid bioavailability and treatment effects in children may depend partially on body size (smaller 
children exhibit higher fatty acid levels for a given dose than larger children). Many pediatric 
medications are dosed based on body weight; however, this concept has been virtually never 
applied to fatty acid supplementation. Aside from considerations about body size, only rarely are 
fatty acid supplements subjected to dose-ranging trials where a variety of doses are examined 
simultaneously to identify the most efficacious and tolerable. At most, a few studies have tested 2 
doses vs. placebo. These gaps in the literature represent a barrier to informing patients and 
clinicians about optimal dosing for a given child, with the end result that some children likely take a 
dose too small to benefit. 
2.6 Consideration of Comorbidities Common in ASD 
In addition to the social-communication and behavioral features of ASD, many individuals with ASD 
have other comorbidities that impact overall health and daily functioning including at least 34% have 
gastrointestinal problems like constipation, 34% are overweight and 18% are obese. Theoretically, 
these conditions may modify the effect of fatty acid supplementation on core ASD symptoms by 
inhibiting gastrointestinal absorption of the supplement or by sequestering a portion of ingested fatty

need to consider these possible treatment modifiers when establishing inclusion/exclusion criteria, 
setting a target sample size, and selecting dose(s).

3 STUDY AIMS 
 
The aims of this project are to: 
 
1)  Optimize safety and bioavailability of Omega 3-6 in a unique 
population of children with ASD.  
  
2)  Evaluate the effect of Omega 3-6 on the biological signatures of 
inflammation (IL-1β, IL-2, IFNγ).  
  
 
 
3.1 Study Outcome Measures 
 
Primary Endpoint (Aim 1): Group differences in bioavailability (each fatty acid as a percent of total 
erythrocyte fatty acids at the end of the trial) and safety (number of and types of adverse events). 
 
Primary Endpoint (Aim 2): Changes in the biological signatures (IL-1β, IL-2, IFNγ) from baseline 
to the end of the trial.

4 STUDY DESIGN 
4.1 Study Participants 
This single-site study will be conducted at Nationwide Children’s Hospital (NCH). We will recruit 
from among patients who have received an ASD diagnosis at NCH within the prior 6 months. We 
expect large numbers of available and interested participants because NCH diagnoses over 800 
children with ASD each year, and recruitment into past treatment studies in this patient population 
has been very successful. Children evaluated at NCH for ASD undergo a comprehensive 4-6 hour 
evaluation with a developmental pediatrician, psychologist, and speech pathologist covering all 
DSM-5 defined ASD criteria, cognitive ability, adaptive behavior, and other behaviors commonly 
comorbid with ASD like hyperactivity, based on trained clinician evaluation and parent report. 
Children who are given the ASD diagnosis including a score on the gold standard Autism Diagnostic 
Observation Schedule-2 (ADOS-2) in the “autism” range which is on the severe end of the 
spectrum, and who meet the other eligibility criteria for the study will be recruited. We focus on 
children in this range to reduce the heterogeneity of the sample and to maximize the probability of 
benefit. 
After diagnosis, children will be evaluated for trial eligibility based on medical record review and 
parent interview. Parents will be contacted via letter, phone, and/or email to discuss participation.  
Inclusion criteria: age 2-6 years, ASD diagnosis at NCH within prior 6 months with an 
ADOS-2 score in the “autism” (severe) range, English is primary language. 
Exclusion criteria: fatty acid supplements in the past 6 months, consume fatty fish >3 
times/week, still breast or formula feeding; quadriparesis; deafness; seizure disorder, 
blindness; bleeding disorder; autoimmune disorders including Type I diabetes; Fragile X, 
Rett, Angleman Syndromes; Tuberous Sclerosis; feeding problems precluding consumption 
of the supplement; ingredient allergy; planned surgeries scheduled within the timeframe of 
trial participation. 
 
Additionally, and as part of the informed consent process, Study Staff will ensure that parents have 
a good understanding of study procedures and are able to comply with study procedures for the 
entire length of the study.

5 STUDY ENROLLMENT, TREATMENT ASSIGNMENT, AND WITHDRAW 
5.1 Enrollment 
The target sample size for this dose-ranging study is 66 children. The study team will be alerted by 
the electronic medical record system when an autism diagnosis is made at NCH for a potentially 
eligible child. The system is updated nightly and study staff will be electronically notified of new 
diagnoses biweekly. Before contacting potential participants for recruitment purposes, the medical 
record will be used to prescreen potentially eligible participants. During this process, study staff will 
examine the ASD diagnostic evaluation to determine if the child meets the inclusion criteria and is 
not excluded due to any exclusion criteria. The medical record will be screened for eligibility 
information, but eligibility will also be confirmed with a legal guardian prior to enrollment.  
5.1.1 
Medical Record Data  
The following data items will be collected from the child’s medical record: 
 
Results of the comprehensive ASD evaluation conducted at the NCH Child Development 
Center including scores from developmental and behavioral testing and clinical summary 
notes 
 
Related diagnoses including gastrointestinal disorders and other developmental and 
behavioral diagnoses (e.g., ADHD) and dates of diagnoses 
 
Demographic and participant characteristics (Date of birth, Sex, Race, Ethnicity, Medical 
insurance payor, Language, Life status, Multiple birth) 
 
Percent no shows to appointments 
 
Food allergies 
 
Current medication list 
 
Contact information 
5.1.2 
Recruitment Mailing 
An introductory letter and informational study brochure will be sent to all eligible families after the 
electronic medical record screening phase. This letter will briefly introduce the study and be signed 
by Dr. Keim and Dr. Rogers. The introductory letter and study brochure will briefly describe the 
purpose of the study and will provide contact information for study staff.  This informational mailing 
will request change of address information from the post office to identify families who have recently 
moved. Although we expect up-to-date contact information to be available in the electronic medical 
record due to the recent NCH diagnostic appointment, contact information may be verified and/or 
attempts to locate unreachable families (e.g., those with outdated contact information on file) will be 
made using a web-based online search service that provides a fast and effective way to look-up or 
verify contact information about a person, phone number or address of interest. Contact information 
will be verified using names, addresses, and phone numbers. 
 
 
5.1.3 
Recruitment Contact 
Study staff will phone the family approximately one week after mailing the introductory letter and 
study brochure to further assess eligibility and gauge general interest in participating.  Study staff 
will use the phone script devised for this study as a conversation guide. During this phone call, 
study staff will provide a description of the study and its requirements. If the family is interested in 
participating, study staff will describe the study to the legal guardian and ask if the guardian and 
child are interested in coming into Nationwide Children’s Hospital to enroll in the project. During this 
appointment, study staff will meet with the guardian to provide detailed information about the study 
and answer any questions the guardian may have. If the parent is interested in enrolling his/her

child and the child meets all eligibility criteria and is not excluded based on the exclusion criteria, 
study staff will guide the parent through the informed consent process. Participation or refusal to 
participate in the study will not affect the child’s entitlement to clinical care.  
This study intends to enroll children a special population and will accordingly adhere to additional 
protections specified under 45 CFR Part 46 Subpart D – Additional Protections for Children Involved 
as Subjects in Research (45 CFR Part 46.401-409). 
5.1.4 
Treatment Assignment  
Study staff will develop a detailed Standard Operating Procedure (SOP) for Randomization and 
Blinding, and Emergency Unblinding Procedures. This SOP will describe how the randomization 
scheme will be generated and that the scheme will be stored in a locked cabinet.  
5.1.5 
Randomization and Masking Procedures 
Randomization will involve a stratified block design of randomly varying block sizes of 6 and 12 
with equal allocation to each of the two study arms. A pseudorandom number generator in the 
statistical software package R will be used by Dr. Rausch to implement randomization, and he 
will maintain the randomization sequence such that it is unavailable to other team members. 
Randomized block sizes will be generated within each of 4 strata formed by crossing 2 
stratification variables: age (2-3 vs 4-6 years) and sex. This stratification design minimizes 
confounding across groups due to the stratification variables. This block design assures a 
balanced allocation across the 2 study arms. Randomly varying block sizes reduces the chance 
that study staff can guess the next group assignment and thus minimizes unconscious bias in 
patient allocation in the RCT. Furthermore, having an experienced statistician not otherwise 
involved in study operations produce the randomization scheme will help maintain blinding 
which is critical to the integrity of the trial and the value of the findings. Investigators, staff, 
parents, and participants will be blind to treatment assignment until all data are collected 
whereupon only those involved in analysis will be unblinded as needed. One to two staff people 
(Adherence Aides) will be unblind and have the sole role of counseling families with strategies 
for protocol compliance (encouraging children to ingest the assigned volume) during scheduled 
phone calls. In order to perform this duty, they will need to have access to information about 
assigned dose.  
 
 
Dr. Rausch will create tamper-resistant opaque envelopes. These will be sequentially numbered 
with study ID numbers (a sequence prepared for each of the 4 total strata).  These will be placed 
in sequence in 4 labeled and secured boxes, one for each stratum. Each time a participant is 
recruited the next envelope in order will be drawn from the stratum specific box that corresponds 
to that participant’s stratum. Inside each envelope will be a designation (e.g., one of six letters of 
the alphabet) for assignment to treatment or placebo and at which dose. This designation will not 
be revealed to families. The participant will be registered in the electronic medical record system 
and the study doctor will print and sign the prescription. The participant study ID will be added to 
this prescription. Study staff will alert the NCH Investigational Drug Service as to the enrollment 
and randomization of the participant and the participant’s weight. IDS will be given the signature 
page of the consent form and the prescription. IDS will have access to the randomization scheme 
so they can match the letter designation and ID to the appropriate treatment and dose. IDS will 
prepare the prescription and the oil will be distributed directly from the pharmacy to the family to 
prevent unblinding of study staff.

5.1.6 
Emergency Unblinding 
An emergency unblinding SOP also will be generated. Only the IRB or PI are allowed to authorize 
early unmasking in the event of emergency. Otherwise, the randomization assignments will be kept 
secure until closure of the study. 
5.1.7 
Withdraw 
Study participation will be discontinued under the following circumstances: 
 
1. PI or Study Doctor believe it is in the best interest of the participant; 
 
2. Participant’s legal guardian requests withdraw from the study; 
 
3. Any clinical AE, laboratory abnormality, intercurrent illness, or other medical condition or 
situation occurs such that continued participation in the study would not be in the best 
interest of the child, as determined by the PI and Study Doctor; or 
 
4. Development of any exclusion criteria may be cause for discontinuation. 
 
5. Study instructions are not followed, participation in the study may also be stopped 
Withdrawal from the study will not affect the receipt of clinical care at NCH. If the study is halted for 
any reason, participants will be instructed to discontinue taking the assigned treatment and return 
the unused portion to study staff.  Participants who choose to discontinue taking the assigned 
treatment during the study will continue to be followed for assessment of the outcomes, and their 
discontinuation will be recorded in the study database. Participants who continue to participate but 
are found to have low adherence to the assigned treatment oil or placebo oil will not be withdrawn 
and will continue to be followed. 
5.1.8 
Handling of Withdrawals 
The study will continue to collect safety data on any participant discontinued because of an AE or 
serious adverse event (SAE). If a participant stops taking the assigned oil, the participant will be 
asked to continue scheduled evaluations.  
5.1.9 
Termination of Study  
Because interventions based on products with similar composition have not found harm to young 
children, it is not anticipated that the study would need to be terminated due to development of 
toxicities or adverse events due to the intervention.  However, the study will be terminated if the PI, 
Study Doctor, IMC, or IRB conclude based on their findings that termination is in the best interests 
of the participants.

6 STUDY PROCEDURES AND SCHEDULE OF EVENTS  
Participation will last for 90 days. The study will involve three in-person study visits at 0, 45 and 90 
days and one remote “e-visit” at 25 days. Visit 1 will involve informed consent, randomization, 
gathering anthropometric data, parent completed questionnaires, distribution and explanation of the 
study diaries, a 3 mL blood collection, and distribution of the treatment oil/placebo oil. This visit will 
last approximately 90 minutes. Day 25 e-visit will review the study diaries to date, assess 
compliance, barriers to participation, and adverse events. Visits 2 and 3 will last approximately 60 
minutes. They will involve returning all oil bottles distributed at the prior in-person visit, review of 
study diaries, assessment of compliance and adverse events, parent completed questionnaires, 
and a 3 mL blood collection. In addition, study staff will check in with families at four other time 
points (Day 5 +/-3 days, Day 35 +/-7 days, Day 60+/-7 days, and Day 80 +/-7 days) to assess 
compliance, adverse events, and barriers to participation. We will ask families for updated contact 
information at the end of each study visit, as well as to provide up to three additional contacts (e.g., 
friends/family) who we may contact if their contact information becomes outdated. 
6.1 
Visit 1 (Day 0)  
The enrollment visit will consist of the following activities: 
 
Informed Consent: See Informed Consent section. 
 
Randomization: After consent, families will be randomized. See Randomization and Masking 
Procedures.  
 
Blood Collection: To measure baseline fatty acid levels, a trained pediatric phlebotomist will draw 3 
mL whole blood into a purple top tube.  
 
Anthropometrics: Child weight and height will be measured using SECA scales and stadiometer to 
inform IDS in calculating the assigned dose. If child cannot be accurately weighed, staff will use 
most recent weight found in medical record system (EPIC). 
 
Parent Perception of Treatment Group: Parents will be asked what treatment group they believe 
their child will be in. 
 
Barriers to Participation: The family’s intentions to complete the study, attend the next study visit, 
and give their child the assigned oil on a daily basis throughout study duration. 
 
Parent Interview: A parent interview will gather baseline child and family characteristics (sex, age, 
socioeconomic index) to characterize the sample and verify comparability across groups. In 
addition, parents will complete the Baylor fatty acid-specific food frequency questionnaire as an 
interview to measure usual dietary intake of long-chain fatty acids. Finally, parents are asked to 
report on current medications, upcoming surgeries, as well as use of complementary and behavioral 
therapies or programs.  
 
Supplement Dispension: Study staff will counsel families on instructions for taking the daily 
treatment oil/placebo oil, how to record each dose in a provided daily study diary, and reporting 
adverse events. IDS will dispense (4) 8 oz. bottles of assigned oil, which will be ample for the 
majority of participants. If child weighs more than 32 kg, an extra bottle will be dispensed at Visit 1 
and Visit 2. IDS will dispense the assigned oil directly to the family and will further instruct on taking 
the assigned oil.

E-Visit (Day 25  +/- 7 days phone contact) 
This visit will be a remote “E-Visit” via phone and will include the following activities: 
 
Parent Perception of Treatment Group and Adherence: Parents will be asked what treatment group 
they perceive their child to be in and to estimate what proportion of doses they administered out of 
the desired number and what proportion of the assigned oil they estimate their child usually 
consumed. Study staff will review study diaries use with the parent and will probe for any problems 
encountered that reflect acceptability, tolerability or compliance. Study staff will request that the 
caregiver take photos of each study diary page used thus far. Caregiver will email or text study staff 
with these photos.  
 
Adverse Events: Parents will be asked if the child has any health or behavior changes since the last 
communication. We will use a modified version of the Safety Monitoring Uniform Report 
Form (SMURF) to document adverse events. 
 
Barriers to Participation: The family’s intentions to complete the study, attend the next study visit, 
and give their child the assigned oil on a daily basis throughout study duration; as well as any 
anticipated barriers to study participation are assessed during each contact with the family.  
 
To simplify our recruitment and retention materials, participants will see that there are 3 in-person 
visits and 5 follow up phone calls. This “E-Visit Day 25” phone call will be one of the five follow-up 
contacts. 
6.3 
Visit 2 (Day 45  +/- 14 days)  
This visit will consist of the following activities: 
 
The following activities will follow the same procedures as for Visit 1: Blood Collection, Parent 
Interview, Parent Perception of Treatment Group and Adherence, Adverse Events, Barriers to 
Participation.  
 
Supplement Return: Families will return all previously dispensed oil bottles to IDS for calculating of 
used/unused portion.  
 
Supplement Dispension: IDS will dispense (4) 8 oz bottles of assigned oil (extra bottle will be 
dispensed if child is over 32 kg). IDS will dispense the assigned oil directly to the family and will 
further instruct on taking the assigned oil. Completed study diary pages will be scanned and diary 
returned. New diary dispensed as necessary.   
 
Compensation: Compensation will be the same as for Visit 1. In addition, families will receive $2 for 
every study diary returned at the study visit (1 diary page covers a 2-week period).

6.4 
Visit 3 (Day 90 +/- 14 days)  
The final visit will consist of the following activities: 
 
The following activities will follow the same procedures as for Visit 2: Blood Collection, Parent 
Interview, Parent Perception of Treatment Group and Adherence, Adverse Events, Supplement 
Return. 
 
Anthropometrics: Child weight and height will be measured using SECA scales and stadiometer.  
 
Supplement Return: Families will return any empty assigned oil bottles and any partially used or 
unopened assigned oil bottles to IDS.  
 
Compensation:  Compensation will be the same as for Visit 2, except if families completed all 4 
study visits (1 of which is the E-Visit), they will receive an additional $20 incentive. Families will 
receive $2 for every study diary returned at the study visit (1 diary page covers a 2-week period). 
 
6.5 
Additional Routine Communication (throughout participation)  
In addition to the study visits, study staff will routinely check in with families at least 5 times (more if 
a family requires additional support) spaced between the visits to assess adherence, adverse 
events, and barriers to participation. These checks may take place in person, over the phone, or 
through email or text, depending on family preference and ease of communicating.  
 
Families will be reminded of scheduled/upcoming appointments via phone, email and/or text (based 
on family preference). Attempts will be made via phone, email, text, and/or mail to contact families 
who do not show for their scheduled visits. During these communications, both remotely and in 
person, parents may be asked to estimate what proportion of doses they administered out of the 
desired number and what proportion of the assigned oil they estimate their child usually consumed. 
Interim study diary data will be collected in the form of photos (of each completed study diary page) 
as often as possible from caregiver via email or text. This will assist in keeping families engaged in 
study diary use and will provide data if study diaries cannot be returned at in-person visits. Study 
staff will work with the family to increase adherence where possible. We will use the modified Safety 
Monitoring Uniform Report Form (SMURF) to document adverse events. Children who do not return 
for the 2 in-person follow up visits will be considered lost to follow-up, but attempts will be made to 
contact them via phone at these pre-prescribed intervals. 
 
6.6 
Rationale for Data Collection 
Data are collected to: 
 
1) Assess demographic and other participant characteristics, thereby allowing a check of the 
randomization procedure and to report on the composition of the sample; 
2) Assess the outcomes of interest; and 
3) Determine the feasibility of and aims for the next stage of research.

7 LABORATORY EVALUATIONS  
7.1 
Specimen Preparation, Handling, and Shipping 
Instructions for the preparation, handling, and storage of specimens are explained clearly in the 
study’s SOP, including required temperatures, aliquots of specimens, where they will be stored, and 
how they will be labeled. Samples will be stored at -80oC until analysis in Dr. Lynette Rogers’ 
laboratory in the Center for Perinatal Research. All laboratory analyses of biospecimens will be 
conducted by Dr Rogers. Serum and RBC samples will be collected from patients at 3 time points to 
determine bioavailability of the supplement in this specific population and to measure the effects of 
treatment on biological signatures.  
 
Fatty acids will be measured in patient red blood cells by standard protocols using gas 
chromatography and will include: capric (10:0), lauric (12:0), myristic (14:0), palmitic (16:0), 
palmitoleic (16:1n-7), steric (18:0), oleic (18:1 n-9), vaccenic (18:1n-7), linoleic acid (18:2 n-6), 
-linolenic acid (18:3 n-3) , -linolenic acid (18:3 n-6), dihomo γ-linolenic acid (DGLA, 20:3 n-6) 
arachidonic (AA, 20:4n-6), eicosapentaenoic acid (EPA, 20:5 n-3), and docosahexaenoic acid 
(DHA, 22:6 n-3).  High and low controls will be run with each batch analysis and a run will be 
considered non-valid if the controls are greater than 2 standard deviations from the mean values 
for DHA, EPA, and GLA.  A non-valid analysis will be discarded and the samples will be re-
analyzed.  Biological signatures will include the cytokines IL-1β, IL-2, IFNγ.  These inflammatory 
cytokines will be measured using an ELISA based technology offered by Meso Scale Discovery. 
   
Any remaining specimens will be maintained in a secured freezer in the Center for Perinatal 
Research, or Center for Biobehavioral Health (depending on space availability) at NCH for future 
research use.  Only the investigators for this study will have access to these specimens and 
permission for future use.  The consent form for the study will state that leftover specimens may be 
used for studies of ASD, child development or nutrition conducted only by the investigators for the 
present study. 
 
7.2 
Biohazards 
Blood samples will be obtained from study participants at each visit.  This service will be 
provided by the Outpatient Lab at Nationwide Children’s Hospital.  As a back-up, Clinical 
Research Services nursing staff can perform this duty. All personnel will be trained in the 
handling of biohazardous samples and are experienced in working with children in these 
situations.  Blood samples will be separated prepared for storage by personnel trained in 
handling hazardous biological samples.  All procedures will follow Good Clinical Practice and 
federal, state, and institutional regulations and guidelines.

8 INVESTIGATIONAL PRODUCT 
8.1 
Acquisition 
Nordic Naturals Complete OmegaTM liquid (treatment oil) will be provided by Nordic Naturals 
(Watsonville, CA).  Bulk canola oil will be purchased from Welch, Holme and Clark Co., Inc. (Newark, 
NJ).  The PI will request an initial supply of the treatment oil and placebo oil to be delivered to IDS 
prior to the study commencing. Additional products will be requested as needed. All treatment oil will 
come from the same manufacturing batch. A sufficient supply of the oils will be maintained in IDS 
throughout the study.  
8.2 
Formulation, Packaging, and Labeling 
The treatment oil will be provided by Nordic Naturals in blue glass bottles. It is available over-the-
counter. The Nordic Naturals Complete OmegaTM liquid contains in each 1 tsp (5ml): 
 
 
 
Welch, Holme and Clark Co., Inc. will provide the canola oil placebo. Although fatty acid 
composition varies slightly with each lot of the canola oil, the distributor provides average fatty acid 
composition per 2.5 ml (2.3g) daily serving. Specifically, each 2.5 ml serving of the canola oil 
placebo contains 124 mg of palmitic acid, 39 mg stearic acid, 513 mg linoleic acid, 225 mg linolenic 
acid, and 1346 mg oleic acid.  The bulk canola oil placebo will be shipped from the distributor in 5-
gallon shipments to NCH IDS who will mix the oil with lemon oil at 1:66.6 (1.5 mL of lemon oil per 
100 mL of canola oil). In this way, the treatment oil and placebo oil will be indistinguishable in terms 
of appearance, smell and taste. IDS will bottle and cap the placebo oil in identical bottles and caps 
as the treatment oil.

8.3 
Dispension 
Each participant who is 32 kg or less will receive four 8 oz bottles of assigned oil at Visits 1 and 2. An 
additional bottle will be dispensed at T1 and T2 if participant is over 32 kg. At the initial dispension, a 
prescription will be delivered to IDS, signed by the Study Doctor. At this point, IDS will select the 
appropriate product, determine the appropriate dose based on child’s weight and group randomized, 
and place a label conducive to Ohio BOP and FDA regulations is placed on each bottle of the 
treatment oil or placebo oil before being dispensed. Additionally, the amount of product dispensed to 
a participant is recorded in an overall master log, maintained by IDS. No information on the bottles 
will indicate which product is contained in them upon dispension from IDS.  
 
In the case of a participant requiring additional supplies of assigned oil (spillage, losing a bottle), 
interim dispensions can occur via shipping product to the family’s home. One 8 oz. bottle (or more if 
necessary) will be provided in these instances. 
8.4 
Product Storage and Stability 
The treatment oil and placebo oil will be kept in a dry, secured environment, controlled and 
monitored for the appropriate temperature. The expiration dates on the products will be monitored 
by IDS to ensure product freshness. The treatment oil and placebo oil will be kept refrigerated to 
maximize freshness. All families will be instructed to keep their bottles refrigerated.  
8.5 
Dosage, Preparation and Administration  
Children are randomized to receive 25 mg, 50 mg, or 75 mg of Omega 3-6 (treatment group) or equal 
volume of placebo oil to be administered twice per day by mouth for 90 days. 
8.6 
Modification of Investigational Product  
No circumstances are known for which the dose should be modified. 
 
8.7 
Accountability Procedures for the Investigational Product 
IDS will monitor the receipt of the treatment oil and placebo oil from the manufacturers, dispension 
of the treatment oil and placebo oil to participants, the return of the treatment oil and placebo oil 
from participants, and the appropriate disposal of any unused assigned oils.  
8.8 
Assessment of Subject Compliance with the Investigational Product  
Parents will be provided with a series of paper diaries and instructions to record whether the child 
consumed the assigned oils each day and what proportion they consumed each day as well as any 
acceptability or tolerability issues. Set of study diaries will be dispensed at Visit 1. Pages of this 
diary will be scanned and diary will be returned. A new set of study diaries can be dispensed at 
follow up visit or by mail as needed. Photos of any completed study diary pages will be requested 
from caregivers during follow up contact. Caregivers will text or email photos of these pages to 
study staff. See Study Procedures and Schedule of Events for procedures for assessment of 
compliance.  
8.9 
Concomitant Medications/Treatments 
There are no restrictions on what drugs or treatments may be concomitant with the study 
intervention.

9 RISKS AND BENEFITS 
9.1 
Risks 
All of the research related procedures, surveys, and questionnaires, are designed to meet the 
definition of “minimal risk” in the federal regulations [§45 CFR 46.102(i)] and to be reviewed by IRBs 
under §45 CFR 46.404 “Research not involving greater than minimal risk.” Minimal risk as defined 
in the federal regulations means “that the probability and magnitude of harm or discomfort 
anticipated in the research are not greater, in and of themselves, than those ordinarily encountered 
in daily life or during the performance of routine physical or psychological examinations or tests.” In 
addition, the Study Staff is committed to minimizing risks even when the risks are minimal.  
 
The informed consent process will take place in private. Questionnaires will be structured to avoid 
creating discomfort for the research participants; and participants will be reminded at each data 
collection encounter that participation is voluntary, that they have the right to withdraw from the 
research project at any time, and they may refuse to answer or may skip any question. 
 
Experienced pediatric phlebotomists staff will perform biospecimen collections that involve minimal 
discomfort or pain. All staff involved in collection of biospecimens will be credentialed accordingly. 
The physical risks of drawing blood by placing a needle in a vein may cause pain, lightheadedness, 
bleeding, bruising, or swelling at the puncture site.  Infection is a rare possibility.  No alternatives to 
blood collection exist to reliably assess fatty acid and inflammatory status in humans. 
 
The risks of collecting and storing linked clinical data and biospecimens are primarily psycho-social. 
Developing coding strategies to mitigate these risks is a fundamental ethical requirement of the 
study. Potential harm could result from a breach of confidentiality. One of the primary concerns is 
that employment and insurance discrimination might result from exposure of information about 
health history, genetic makeup, or familial predisposition to disease. The risk is minor, especially 
since unique participant identifiers will not be stored with biospecimens. 
The Nordic Naturals Complete OmegaTM liquid product contains a combination of fish and borage 
oils.  These oils include several LCPUFAs including eicosapentaeonic acid (EPA) and gamma-
linolenic acid (GLA).  Although giving EPA to preterm infants (i.e., children much younger than 
those eligible in this study) has been found to pose some risk related to poorer growth in a single-
site study that has not been replicated,32 numerous other infancy and post-infancy studies using 
EPA have not reported adverse effects. Because EPA also can increase bleeding time, albeit 
generally clinically insignificantly, children with existing bleeding disorders will be excluded from 
participation. Children with planned surgeries will be excluded. 
The presence of borage oil in the supplement contributes the GLA content. Most of the safety 
information available about GLA comes from studies that used evening primrose oil, another major 
source of GLA. Animal studies have shown no toxic or carcinogenic effects.33 Previous human 
studies have involved over 4,000 individuals, and no significant adverse effects have been reported. 
There have been two case reports of excessive intake of borage oil or other GLA-containing 
supplements causing worsening seizures in epileptics, but there have been no published cases or 
studies since these reports were published in 1981.34 Although the likelihood of this occurring in the 
present study is very low, children with a seizure disorder will be excluded from the study.  A 2004 
study of 238 preterm neonates evaluated an infant formula with fish and borage oil compared to a 
vegetable oil formula fed to infants for 9 months.35 Daily intake amounts varied based on volume 
consumed, but the fish and borage oil group received up to an estimated 26mg per day of GLA. 
This is the equivalent of between 3 and 17 mg/kg/day depending on the child’s body composition

CONFIDENTIAL                                                                                                                                                                 22 May 2018

and age. Although Fewtrell and colleagues35 stated adverse events were present in both formula 
groups, the fish and borage oil group experienced more days on ventilator, more days on oxygen, 
and more days with umbilical catheter. Although these adverse events were reported, many pre-
existed randomization.  The infants in that study were already NICU patients with multiple co-
morbidities present before randomization. Because of the older age of the participants in this study, 
adverse events such as those reported by Fewtrell and colleagues are not anticipated.35 
The placebo for this study will be canola oil with a natural lemon oil flavoring added.  Canola oil is a 
commonly consumed food present in many prepared food products.  Whether it is possible to have 
an allergy to canola/rapeseed is controversial, but very rarely some people may have a non-allergic 
reaction. Nevertheless, we will exclude any children whose parent states they have 
canola/rapeseed allergy or sensitivity.  Lemon oil is Generally Recognized as Safe (GRAS) by the 
FDA. 
 
The study staff will maintain confidentiality of the data in its databases. Data will be summarized in 
aggregate for reporting purposes. Data submitted to the study does include participant identifiers, 
as defined by the U.S. Health Insurance Portability and Accountability Act of 1996 (HIPAA).  The 
study will follow all necessary measures to assure the participant data stored in the database are 
protected and secure from unauthorized access.   
The knowledge to be gained from this investigation outweighs these minimal risks. This study has 
the potential to inform future dietary recommendations for children, especially those diagnosed with 
ASD and associated comorbidities. 
9.2 
Benefits 
Omega fatty acid supplementation may benefit participating children by reducing their ASD 
symptomology, and comorbidities. It is not known if these benefits exist. Participation in this study 
will aid in acquiring new knowledge that might help other children with an ASD diagnosis and their 
families in the future.  
 
There are no other known benefits expected from participation in this study.

10  ASSESSMENT OF SAFETY 
10.1 Methods and Timing for Assessing, Recording, and Analyzing Safety Parameters 
Safety oversight will be under the direction of the Principal Investigators (PIs), Study Doctor, and 
the Independent Study Safety Monitor. All adverse events will be reviewed to rule out the study 
intervention as a potential cause. All Adverse Events will be recorded on a form designated for 
that purpose, labeled with a participant ID and no personal identifiers. For any adverse events 
required to be reported to the IRB or the FDA, and for review purposes by the Independent 
Monitoring Committee (IMC), only the coded ID number will be included in the documentation as 
needed, and no identifiers. The IMC will review adverse events anonymously. If the child’s 
medical record must be accessed to provide additional details as to the event or its treatment, 
study staff will provide abstracted information that is de-identified. Annual reports of findings will be 
submitted to the FDA in line with IND regulations. 
   
10.2 Adverse Events 
Adverse Event (AE):  ICH E6 defines an AE as any untoward medical occurrence in a patient or 
clinical investigation participant administered a pharmaceutical product regardless of its causal 
relationship to the study treatment. An AE can therefore be any unfavorable and unintended sign 
(including an abnormal laboratory finding), symptom, or disease temporally associated with the use 
of investigational product. The occurrence of an AE may come to the attention of study personnel 
during study visits and interviews of a study recipient presenting for medical care, or upon review by 
a study monitor.  
All AEs including local and systemic reactions not meeting the criteria for “serious adverse events” 
should be captured on the appropriate CRF. Information to be collected includes event description, 
time of onset, Study Doctor’s assessment of severity, relationship to study product (assessed only 
by those with the training and authority to make a diagnosis, which would include MD, PA, Nurse 
Practitioner, DO, or DDS), and time of resolution/stabilization of the event. All AEs occurring during 
study participation must be documented appropriately regardless of relationship. All AEs will be 
followed to adequate resolution.  
Any medical condition that is present at the time that the participant is screened should be 
considered as baseline and not reported as an AE. However, if the medical condition deteriorates at 
any time during the study, it should be recorded as an AE. 
All AEs must be graded for severity and relationship to study product.  
Severity of Event:  All AEs will be assessed by the Study Doctor using a protocol defined grading 
system. For events not included in the protocol defined grading system, the following guidelines will 
be used to quantify intensity.  
 
Mild: events require minimal or no treatment and do not interfere with the participant’s daily 
activities. 
 
Moderate: events result in a low level of inconvenience or concern with the therapeutic 
measures. Moderate events may cause some interference with functioning. 
 
Severe: events interrupt a participant’s usual daily activity and may require systemic drug 
therapy or other treatment. Severe events are usually incapacitating.

CONFIDENTIAL                                                                                                                                                                 22 May 2018

 
Life threatening:  any adverse drug experience that places the participant, in the view of the PI, 
at immediate risk of death from the reaction as it occurred (i.e., it does not include a reaction 
that had it occurred in a more severe form, might have caused death). 
Changes in the severity of an AE should be documented to allow an assessment of the duration of 
the event at each level of intensity to be performed. Adverse events characterized as intermittent 
require documentation of onset and duration of each episode. 
Relationship to Study Products:  The Study Doctor’s assessment of an AE's relationship to study 
intervention is part of the documentation process, but it is not a factor in determining what is or is 
not reported in the study. If there is any doubt as to whether a clinical observation is an AE, the 
event should be reported. All AEs must have their relationship to study product assessed using the 
terms: related or not related. In a clinical trial, the study product must always be suspect. To help 
assess, the following guidelines are used. 
 
Related (Possible, Probable, Definite) 
a. The event is known to occur with the study intervention. 
b. There is a temporal relationship between the intervention and event onset. 
c.   The event abates when the intervention is discontinued. 
d. The event reappears upon a re-challenge with the intervention. 
 
Not Related (Unlikely, Not Related) 
a. There is no temporal relationship between the intervention and event onset.

10.3 Unanticipated Problems 
The Office for Human Research Protections (OHRP) considers unanticipated problems 
involving risks to subjects or others to include, in general, any incident, experience, or outcome 
that meets all of the following criteria: 
 
Unexpected in terms of nature, severity, or frequency given (a) the research procedures 
that are described in the protocol-related documents, such as the IRB-approved 
research protocol and informed consent document; and (b) the characteristics of the 
subject population being studied; 
 
Related or possibly related to participation in the research (“possibly related” means 
there is a reasonable possibility that the incident, experience, or outcome may have 
been caused by the procedures involved in the research); and 
 
Suggests that the research places subjects or others at a greater risk of harm (including 
physical, psychological, economic, or social harm) than was previously known or 
recognized.

10.3.1 
Reporting Unanticipated Problems 
Incidents or events that meet the OHRP criteria for unanticipated problems will be reported 
using an unanticipated problem report form.  The unanticipated problem report form will include 
the following information when reporting an adverse event, or any other incident, experience, or 
outcome as an unanticipated problem to the IRB: 
 
Appropriate identifying information for the research protocol, such as the title, 
investigator’s name, and the IRB project number; 
 
A detailed description of the adverse event, incident, experience, or outcome;  
 
An explanation of the basis for determining that the adverse event, incident, experience, 
or outcome represents an unanticipated problem;  
 
A description of any changes to the protocol or other corrective actions that have been 
taken or are proposed in response to the unanticipated problem. 
To satisfy the requirement for prompt reporting, unanticipated problems will be reported using 
the following timeline:   
 
Unanticipated problems that are serious adverse events will be reported to the IRB, 
Independent Safety Monitor(s), and NCCIH within 7 days of the investigator becoming 
aware of the event.  
 
Any other unanticipated problem will be reported to the IRB, Independent Safety 
Monitor(s), and NCCIH within 14 days of the investigator becoming aware of the 
problem.  
All unanticipated problems should be reported to appropriate institutional officials (as required 
by an institution’s written reporting procedures), the supporting agency head (or designee), and 
OHRP within one month of the IRB’s receipt of the report of the problem from the investigator. 
10.4 Serious Adverse Events 
Serious Adverse Event (SAE): An SAE is defined as an AE that meets one of the following 
conditions: 
 
 
Death during the period of protocol defined surveillance. 
 
Life-threatening event (defined as a subject at immediate risk of death at the time of the 
event). 
 
An event requiring inpatient hospitalization or prolongation of existing hospitalization during 
the period of protocol defined surveillance. 
 
Results in congenital anomaly or birth defect. 
 
Results in a persistent or significant disability/incapacity. 
 
Any other important medical event that may not result in death, be life threatening, or 
require hospitalization, may be considered a serious adverse experience when, based upon 
appropriate medical judgment, the event may jeopardize the subject and may require 
medical or surgical intervention to prevent one of the outcomes listed above. Examples of 
such medical events include allergic bronchospasm requiring intensive treatment in an

emergency room or at home, blood dyscrasias or convulsions that do not result in inpatient 
hospitalization, or the development of drug dependency or drug abuse. 
The Study PI and Independent Monitoring Committee will be responsible for determining 
whether an SAE is expected or unexpected.  An adverse event will be considered unexpected if 
the nature, severity, or frequency of the event is not consistent with the risk information 
previously described for the intervention.   
 
All SAEs will be: 
 
Recorded on the appropriate SAE CRF. 
 
Followed through resolution by a Study Doctor. 
 
Reviewed and evaluated by a Study Doctor. 
10.4.1 
Reporting SAE’s 
Any AE considered serious by the PI or Study Doctor or which meets the aforementioned criteria 
must be submitted on an SAE form to the NCH IRB within 3 business days of discovery.  All SAEs 
will be followed until satisfactory resolution or until the Study Doctor deems the event to be chronic 
or the patient to be stable.  
 
Annual reports of findings will be submitted to the FDA in line with IND regulations. 
 
SAEs that are unanticipated, serious, and possibly related to the study intervention will be 
reported to the Independent Monitors(s), IRB, FDA, and NCCIH in accordance with 
requirements.  For the IND:  
 
7-day IND Safety Report (unexpected fatal or life-threatening AEs related to the 
intervention); a copy of the report sent to the FDA will be submitted to the NCCIH 
Program Officer and Independent Safety Monitor(s) within 24 hours of FDA notification.  
 
15-day IND Safety Report (any other serious and unexpected AE related to the 
intervention); a copy of the report submitted to the FDA will be submitted to the NCCIH 
Program Officer and Independent Safety Monitor(s) within 24 hours of FDA notification.  
 
All other AEs documented during the course of the trial will be reported to NCCIH on an 
annual basis by way of inclusion in the annual report and in the annual AE summary 
which will be provided to NCCIH and to the Independent Monitors.  The Independent 
Safety Monitor(s) Report will state that all AEs have been reviewed. 
10.5 Procedures in the Event of Abnormal Laboratory Test Values/Clinical Findings 
Collection of laboratory data should be limited to those laboratory parameters that are relevant to 
safety, study outcome measures, and/or clinical outcome. No known fatty acid value is considered 
to be abnormal or to present a safety concern.  As a result, it is not anticipated that any abnormal 
laboratory values will be found. However, any abnormal clinical findings will be reported to the 
child’s physicians.

10.6 
Type and Duration of Follow-up of Subjects after Adverse Events 
Unanticipated problems will be recorded in the data collection system throughout the study.  
The PI will record all reportable events with start dates occurring any time after informed consent is 
obtained until 7 (for non-serious AEs) or 30 days (for SAEs) after the last day of study participation. 
At each study visit, the investigator will inquire about the occurrence of AE/SAEs since the last visit. 
Events will be followed for outcome information until resolution or stabilization. 
10.7  Halting Rules 
If it is found that the study intervention is related to any serious adverse events, enrollment would 
be temporarily suspended until a safety review is convened, the objective of which is a decision as 
to whether the study (or intervention for an individual or study cohort) should continue per protocol, 
proceed with caution, be further investigated, be discontinued, or be modified and then proceed. 
Suspension of enrollment (for a particular group or for the entire study) is another potential outcome 
of a safety review. 
 
Subsequent review of serious, unexpected, and related AEs by the PI, Study Doctor, the 
Independent Study Safety Monitor, the IRB, or the FDA or relevant local regulatory authorities may 
also result in suspension of further trial interventions/administration of study product. The FDA 
retains the authority to suspend additional enrollment and study interventions/administration of 
study product for the entire study, as applicable. 
 
Based on the large number of previous studies that have utilized a similar intervention in children 
and the widespread use of the study products in the U.S. consumer marketplace, there are no 
expectations for halting the study enrollment or intervention due to safety concerns.  However, it will 
be left to the judgment of the PI with the advice of the Study Doctor and Safety Monitor whether a 
pattern of adverse events or other circumstances warrant halting.   
10.8 
Safety Oversight 
Safety oversight will be under the direction of the PIs and Independent Study Safety Monitor. All 
adverse events will be reviewed to rule out the study intervention as a potential cause.

11 STATISTICAL CONSIDERATIONS 
11.1 
Study hypotheses 
This study will test the hypothesis that Omega 3-6 will produce a clinically significant reduction 
(improvement) in plasma levels of IL-1β, IL-2, and/or IFN and assess bioavailability and safety, 
of this product.  
11.2 
Sample Size Considerations 
Our power analysis is based on a comparison on pre-post change between all the placebo 
group participants compared to all treatment group participants receiving any Omega 3-6. We 
use a Type I error rate of .05 to test our primary aim that at least one of our inflammatory 
markers will demonstrate improvements from baseline to posttest compared to the placebo 
group.  
  
For the purposes of examining power, we assume an independent samples t-test on pre-post 
change with ≥80% power to obtain a sufficient per group sample size (n), equal across groups. 
Consequently, the standardized mean difference ) is the effect size of interest. We base our 
estimate of the intervention effect size on our Preemie Tots study where s of .75, .77, and 1.04 
were obtained for the inflammatory markers of IL-1, IL-2, and IFN respectively. We propose 
as part of our go/no-go decision for proceeding to the next phase of research (a second trial). 
This effect size (effect on inflammation) is clinically meaningful, based on the meta-analysis by Masi 
which compared children with ASD to typically-developing children and observed differences in 
cytokine levels ofand 1.0 for 2 of our biomarkers of interest.41 Importantly, the dose used in 
Preemie Tots is comparable to the smallest dose treatment group here; consequently, if a dose 
effect does indeed exist across the treatment groups, we expect the effect sizes we observe will be 
even larger in the present study when compared to the placebo group. Given these effect sizes and 
conservatively accounting for attrition rates of 10%, n=33 for each of the placebo and treatment 
groups will allow us to detect treatment effects with at least 80% power.36  
 
11.3 
Planned Interim Analyses (if applicable) 
No interim analysis is planned.  
 
11.3.1 
Safety Review  
Based on the large number of previous studies that have utilized the same intervention in similar 
populations and the widespread use of the study products in the U.S. consumer marketplace, 
there are no expectations for halting the study enrollment or intervention due to safety concerns. 
 However, it will be left to the judgment of the Principal Investigator with the advice of the IMC 
whether a pattern of adverse events or other circumstances warrant halting.  See the section 
“Assessment of Safety” for details about safety monitoring.

Final Analysis Plan 
 
Aim 1 
Aim 1 Primary Analysis: To examine group differences in bioavailability and safety, we will 
compare the entire treatment group to the entire placebo group, and at the different dosing 
levels within treatment, by: 1) comparing mean and median %FA for each fatty acid at the end 
of the trial and 2) comparing the total number of adverse events that occurred in each group and 
also by adverse event type (e.g., gastrointestinal; severe vs. not).  
 
Aim 1 Secondary analysis: Demonstrate that children receiving Omega 3-6 will exhibit a 
clinically relevant absolute increase in RBC EPA or DHA of at least 0.5 mol%, between baseline 
and the end of the trial (i.e., an increase of approx. 20% for DHA, 67% for EPA depending on 
baseline status). 
 
Aim 1 Secondary analysis (exploratory): Explore the effect of dose on changes in RBC EPA and 
DHA by examining differences in the increase in RBC EPA and DHA by assigned dose among 
children assigned to Omega 3-6. 
 
 
Aim 2  
Aim 2 Primary Analysis: To formally examine the efficacy of the intervention, the primary 
analysis will be to compare the treatment group, where anyone assigned to Omega 3-6 is 
considered a member, to the placebo group where anyone assigned to placebo is a member, on 
pre-post change in each inflammatory marker. 
 
Aim 2 Secondary analysis (exploratory): Explore the effect of dose by 
comparing each Omega 3-6 dose to the placebo group (all children assigned to 
placebo) on pre-post change in each inflammatory marker. 
 
 
The primary approach for the analyses is intent-to-treat: individuals will be kept in the group to 
which they were randomized, regardless of protocol violations or drop-out. Every effort will be made 
to minimize missing data. Analyses will explore plausible missing data mechanisms, and baseline 
predictors of missingness will be investigated. Also, when possible maximum likelihood estimation 
(MLE) will be employed where predictor variables associated with missingness will be investigated 
in sensitivity analyses. MLE generally provides valid inferences when the missing data mechanism 
is missing at random37 and is more appropriate than many commonly employed approaches to data 
imputation.38 
 
We will examine group differences descriptively on bioavailability and safety data for the entire 
placebo group, the entire treatment group, and (secondarily, exploratory) at the different dosing 
levels within treatment. Specifically, for the Primary Analysis in Aim 1, we will use the independent 
samples t-test and the Wilcoxon rank-sum test to examine treatment vs. placebo group differences 
on the %FA for each fatty acid at the end of the trial, the total number of adverse events, and 
number adverse events by event type. This approach will allow us to examine both parametric and 
non-parametric approaches to group differences on each of these measures of bioavailability or 
safety.

For the Secondary Analysis in Aim 1, we will calculate the increase for each of RBC EPA and DHA 
to determine if a clinically relevant value is obtained. For the Exploratory component of our 
Secondary Analysis in Aim 1, we will employ a repeated-measures mixed effects model to examine 
change in each of RBC EPA and DHA as a function of dose within the treatment group only.  
 
For the Primary Analysis in Aim 2 to formally examine the efficacy of the intervention we will 
compare the treatment group where anyone given Omega 3-6 is considered a member to the 
placebo group when anyone given a placebo dose is considered a member on pre-post change in 
each inflammatory marker. The following is an illustration of our statistical model for repeated 
measures (RM), similar to analysis of covariance (ANCOVA) but based on maximum likelihood  
estimation, that will be employed for these analyses39:

y  is the value for a given inflammatory 
marker for individual i at time t, 
t
Time   is coded as 0 for the pretest and 1 for the 90-day post-
treatment, and the primary effect of interest is 
2
, which corresponds to the difference between the 
groups on change in the inflammatory marker of interest. In this RM model, the baseline measure of 
the individual’s inflammatory marker is constrained to have equal means across groups by 
assuming there is no main effect for 
i
Trt . This constraint yields a statistical test for 
2
analogous to 
the test of the treatment group main effect in an ANCOVA covarying the pretest measure of the 
outcome variable. The main advantage of the RM model is that it can be estimated in SAS PROC 
MIXED using maximum likelihood estimation on all available data by treating 
t
Time  as a repeated 
measures factor with 2 levels, whereas an ANCOVA model would require listwise deletion for 
missing data.38  
 
Importantly, for the Secondary/Exploratory Analysis in Aim 2, we will investigate the dose effect by 
using dosage given to a participant as quantitative and categorical predictors within separate 
models in place of the treatment effect variable, 
i
Trt , using the same type of model used in the 
previous analysis. Because of the exploratory nature of our hypotheses concerning the parametric 
form of the relationship between dose and the response in each inflammatory marker, separate 
analyses using quantitative and categorical versions of the dosing variable will allow us to fully 
explicate the dose-response relationship. We will conduct exploratory analyses by child sex to 
examine sex as a modifier.

An Independent Study Safety Monitor or other authorized representatives may inspect all 
documents and records required to be maintained, including but not limited to, data collection 
records and pharmacy records for the subjects in this study. Records will be retained indefinitely. 
14.6 
Study Discontinuation 
In the event that the study is discontinued, participants may discontinue use of the treatment oil and 
placebo oil safely.  There is no known risk to discontinuation.  
14.7 
Future Use of Stored Specimens 
Any residual specimens will be maintained after the study is complete and will be available for 
future analysis and use, per the participant informed consent document.  Specimens may be 
analyzed for future studies of child nutrition, neurodevelopment and behavior and growth.   
Specimens will be maintained in a secure location in the Center for Perinatal Research or Center for 
Biobehavioral Health at NCH and will be labeled with a numeric code and no identifying information. 
This is noted on the consent form and additional consent to bank leftover biospecimens in this 
manner will be obtained from participating families. Only the investigators for this study will have 
access to these specimens and permission for future use.

DATA HANDLING AND RECORD KEEPING 
The PI is responsible to ensure the accuracy, completeness, legibility, and timeliness of the data 
reported. All source documents should be completed in a neat, legible manner to ensure accurate 
interpretation of data. Dark ink is required to ensure clarity of reproduced copies. When making 
changes or corrections, cross out the original entry with a single line, and initial and date the 
change.  
Copies of the CRF will be used as source documents and maintained for recording data for each 
participant enrolled in the study. Data reported in the CRF derived from source documents should 
be consistent with the source documents or the discrepancies should be explained. 
15.1 
Data Management Responsibilities 
All source documents and laboratory reports will be reviewed by the investigator team and data 
entry staff, who will ensure that they are accurate and complete. Adverse events must be graded, 
assessed for severity and causality, and reviewed by the PI or designee. 
 
Data collection is the responsibility of the Study Staff under the supervision of the PI. During the 
study, the investigator must maintain complete and accurate documentation for the study. 
 
The Study Staff is also responsible for data management, quality review, analysis, and reporting of 
the study data under the direction of the investigator team. 
15.2 
Data Capture Methods 
For the purposes of this pilot study, data capture will be via paper and electronic methods (e.g., Red 
Cap).  The data entry system will include password protection and internal quality checks, such as 
automatic range checks and data validation, to identify data that appear inconsistent, incomplete, or 
inaccurate. Clinical data will be entered directly from the source documents.  
15.3 
Types of Data 
Data for this study will include questionnaires, interviews, medical record, and laboratory measures. 
15.4 
Study Records Retention 
Study records will be kept in a secure, locked location in the Center for Biobehavioral Health at 
NCH and kept per procedures laid out in federal regulations. 
15.5 
Protocol Deviations 
A protocol deviation is any noncompliance with the clinical trial protocol, Good Clinical Practice 
(GCP), or Manual of Procedures requirements. The noncompliance may be either on the part of the 
subject, the investigator, or the Study Staff. As a result of deviations, corrective actions are to be 
implemented promptly.  
 
These practices are consistent with ICH E6: 
 
4.5 
Compliance with Protocol, sections 4.5.1, 4.5.2, and 4.5.3 
5.1 
Quality Assurance and Quality Control, section 5.1.1 
5.20 
Noncompliance, sections 5.20.1, and 5.20.2.

PUBLICATION POLICY 
Following completion of the study, the PI is expected to publish the results of this research in 
scientific journals. The International Committee of Medical Journal Editors (ICMJE) member journals 
have adopted a trials-registration policy as a condition for publication. This policy requires that all 
clinical trials be registered in a public trials registry such as ClinicalTrials.gov, which is sponsored by 
the National Library of Medicine. Other biomedical journals are considering adopting similar 
policies.  The PI will register this trial in an acceptable registry.
