Brief summary:
Determine whether peanut oral immunotherapy (OIT) induces clinical tolerance as assessed after the initial 3 month avoidance period

Secondary Objectives:

* Identify the basic immune mechanisms which can explain the differences in the effects of OIT in desensitized vs. tolerant individuals.
* Determine whether immune monitoring measurements reflecting underlying mechanisms during OIT can be used to predict responses to OIT in individual subjects and, ultimately, to improve the safety and efficacy outcomes in peanut OIT protocols.

Detailed description:
All arms will undergo an Initial Dose Escalation (IDE) Day and updosing regimen with a maintenance phase of OIT or placebo to a maximum of 4,000 mg protein daily, as peanut flour, in the OIT groups, and to a maximum of an equivalent amount of oat flour for the placebo group. After maintenance is achieved, all subjects will begin performing DBPCFCs (staged so as to ensure safety) at Week 104 and every 13 weeks thereafter. At Week 104, individuals that reach criteria will, based on the randomization that was done at the start of the study, either stop therapy with peanut and be switched to oat flour, or will be maintained on 300 mg peanut protein per day and all placebo subjects will decrease to the equivalent volume of oat flour (approximately 600 mg oat flour) to optimize the blind. All subjects will be evaluated every 13 weeks thereafter with DBPCFCs until the end of study.

Individuals in Arm A will be defined as "clinically tolerant" if there is no clinical reactivity at the Week 104 and Week 117 DBPCFC. Clinical reactivity is defined as any reaction ≥ Grade 1 based on the Bock's Criteria. Individuals in Arm A who meet the definition of "clinically tolerant" will continue to avoid peanut protein (i.e. continue on 600 mg per day of oat flour) as long as each subsequent DBPCFC (performed every 13 weeks until end of study) shows no clinical reactivity.

Individuals in Arm B will be defined as "desensitized" to a minimum of 300 mg per day of peanut protein if they show no clinical reactivity at DBPCFCs (week 117 to end of study).

Individuals in Arm C will be defined as "natural loss of responsiveness" if they show no clinical reactivity at DBPCFCs (week 117 to end of study).

We plan to identify the basic immune mechanisms which can explain the differences in the effects of OIT in individuals who do or do not become clinically tolerant and to determine whether immune monitoring can predict the safety and efficacy outcomes in peanut OIT protocols.

After initial screening and enrollment, there are three phases of the study:

* Dose escalation and Build up Phase
* Maintenance phase
* Tolerance and Desensitization Testing phase Overall, 120 subjects who are eligible will undergo the Initial Dose Escalation Day. Subsequent updosing visits will occur every 2 weeks as a part of the build-up phase. They will continue to updose until they reach 4,000 mg protein daily, which is the maximum maintenance amount of protein. We expect active OIT treatment subjects to reach 4,000 mg of peanut protein between 44-78 weeks.

Treatment and Desensitization Failures:

A treatment failure will be defined as a) failure to reach 1.5 mg peanut protein (single dose) during the Initial Dose Escalation Day or b) failure to reach 1,000 mg peanut protein by week 104.

Subjects who do not meet the criteria at Week 104 and who demonstrate clinical reactivity will be considered desensitization failures.

If Arm B subjects demonstrate clinical reactivity in any DBPCFC from Week 117 to end of study, they will be considered desensitization failures.

If Arm A subjects demonstrate clinical reactivity (≥Grade 1, in any DBPCFC from Week 117 to end of study, they will be considered tolerance failures.

Treatment failures, desensitization failures, and tolerance failures will be unblinded (both participant and research staff) and will be followed until the end of the study at the specified study visits but will not undergo DBPCFCs. They will be considered in statistical analyses of the intent-to-treat population.

Arms:
arm 1: Arm C that is maintained on placebo (oat flour) throughout the study; this arm will receive 600 mg oat flour beginning on week 104. This will be true even if a subject in the placebo group meets criteria at week 104 arm 2: Arm A on peanut OIT until week 104 (maintenance) and once meeting criteria \[i.e. 1) on OIT treatment for minimum 104 weeks, 2) taking daily maintenance dose of 4,000 mg protein for at least 13 weeks, 3) no severe reactions to home dosing from Week 91-Week 104, and 4) no reactions at the Week 104 DBPCFC\] will be assigned to avoid peanut (i.e. will consume 600 mg oat flour daily) and will proceed to tolerance and desensitization phase. arm 3: Arm B on peanut OIT until week 104 and once meeting criteria specified in description of Arm A, will be assigned to be maintained on 300 mg peanut protein (i.e. 600 mg peanut flour) daily and will proceed to the tolerance and desensitization testing phase.

Interventions: intervention 1: Peanut Protein 4,000mg intervention 2: Oat Flour intervention 3: Peanut Protein 300 mg
Intervention descriptions: intervention 1: Arm A will be defined as "clinically tolerant" if there is no clinical reactivity at the Week 104 and Week 117 DBPCFC. Clinical reactivity is defined as any reaction ≥ Grade 1 based on the Bock's Criteria (Appendix 4). Individuals in Arm A who meet the definition of "clinically tolerant" will continue to avoid peanut protein (i.e. continue on 600 mg per day of oat flour) as long as each subsequent DBPCFC (performed every 13 weeks until end of study) shows no clinical reactivity. intervention 2: Arm C will be defined as "natural loss of responsiveness" if they show no clinical reactivity at DBPCFCs (week 117 to end of study). intervention 3: Arm B will be defined as "desensitized" to a minimum of 300 mg per day of peanut protein if they show no clinical reactivity at DBPCFCs (week 117 to end of study).

Statistical analysis 
Using a binomial test of proportions with two-sided alpha level 0.05, the subject sample sizes 
of 60 in the peanut-0 and 25 in the placebo arms yielded 90% power to detect a difference in the 
success rates, assuming rates of success in the peanut-0 arm between 0.35 and 0.05.   
We designed our study and analysis plan before participant enrollment as specified in the 
protocol. Analyses not specified in the protocol are stated throughout the methods and are 
considered post-hoc. The primary efficacy analysis compared the peanut-0 and placebo arms 
using Fisher’s exact test.10 The primary analysis relied on the ITT group and included all subjects 
randomized to the peanut-0 or placebo arm. Using our endpoint definition (passing the DBPCFC 
at both 104 and 117 weeks) randomized participants who dropped out of the study were included 
in the analysis as failures. If any relevant covariates were imbalanced between peanut-0 and 
placebo, a secondary analysis evaluating the primary endpoint was performed using a 
multivariable logistic regression model controlling for those variables. 
The Supplementary Appendix and study protocol contain more detailed information about 
the statistical analysis plan. Tests for the primary and secondary analyses were two-sided and 
conducted at the 0.05 level of significance. All analyses were conducted using R software 
v3.5.010.

PURPOSE OF RESEARCH 
 
You are being asked to take part in this research study because you have peanut 
allergy.  Peanut allergy occurs in about 2% of children and is the most common 
food to cause life-threatening reactions.   Currently, the primary treatment for 
peanut allergy is a peanut-free diet and ready access to allergy medicine. The 
combination of avoidance diets and risks of accidental exposures and life-
threatening reactions creates a tremendous burden to patients and families. 
Unlike food allergies to milk and egg allergy, peanut allergy tends to persist, and 
only 20% of children outgrow their disease. 
 
The purpose of this study is to find out if treating children and adults with peanut 
allergy with an experimental treatment of peanut oral (by mouth) immunotherapy 
(OIT) will cause them to lose their allergy to peanuts.  There are two terms that 
can describe losing an allergy in this way: “desensitization” and “tolerance.”   
 
A person may become desensitized to a medicine or food by giving that person 
small, increasing amounts of the medicine or food to help the body become used 
to the substance so that it no longer causes a severe allergic reaction.  When a 
person with a food allergy is desensitized, they often have to continue to expose 
their immune system to the food they are allergic to in order to keep their allergy 
from coming back.  If someone who has been desensitized to a food allergen 
stops eating their food allergen every day and their allergy does not come back, 
they are considered to have developed tolerance to that food.   
 
By desensitizing you to peanut protein, we hope to lower the risk of life-
threatening allergic reactions and cause you to have less sensitivity to peanuts.  
But we do not know yet whether this will happen.  In addition, some food allergy

researchers are asking the questions of how long a person who has been 
desensitized has to continue eating their allergic food every day and how much 
they have to eat in order to develop tolerance. 
 
Right now, food allergy researchers do not know how to identify which patients 
will become desensitized by OIT and which will become tolerant after OIT.  That 
is one of the major questions we want to help answer with this study. 
 
This is a research study of an experimental treatment for peanut allergy.  For this 
research, we will study subjects in two different groups. One group will receive 
the experimental treatment of peanut protein and the other group will receive 
placebo (oat flour) for a total of approximately 3 years.  A placebo is an inactive 
substance given in the same form as the peanut protein that is similar to the test 
substance in appearance, smell, and taste but, contains no peanut protein.  
Neither you nor the Protocol Director will be able to choose or know the group to 
which you are assigned.  Subjects will be randomly assigned to the groups (like 
flipping a coin). Out of 120 participants in this study, 95 will be randomly 
assigned to peanut and 25 will be randomly assigned to placebo.  This means a 
participant in the study has a 79% chance of being assigned to peanut and a 
21% chance of being assigned to placebo. 
 
This research study is looking for 120 individuals between the ages 7 and 
55 years old with an allergy to peanut.  All 120 participants will be enrolled at 
Stanford University.  
 
If you decide to terminate your participation in this study, you should notify the 
Protocol Director, Dr. Kari Nadeau (650-867-4592) or the co-Protocol Director Dr. 
Sharon Chinthrajah (267-235-6978).  
 
The study stopping rules were met due to two cases of hypotension (low blood 
pressure) and the study was stopped on November 23, 2016. Two participants 
developed hypotension after they ate peanut and recovered quickly after receiving 
injectable epinephrine. 
 
On November 23rd, the IRB, NIH and FDA were notified of the study stopping rules 
being met. On November 28th, we received notice from the FDA that the study 
could continue. From November 29th-December 1, the FDA reviewed the cases 
and determined the study may continue and that food challenges and dose 
escalations could continue until further information from the DSMB (data safety 
monitoring board) was given.  
 
The DSMB reviewed the cases and safety data from all study participants and the 
DSMB determined, in late December, that the study could continue. The DSMB 
requested that all participants be re-consented. The protocol and consent now 
have new rules on hydration (for both dose escalation and oral food challenge, on

is given—for oral food challenge).  More details are on page 7 and 13 of this 
consent.  
 
In summary, the DSMB asked for changes to be made in the oral food challenges 
and dose escalations to try to further improve safety. The DSMB also asked for 
changes in the study stopping rules. These changes have been made and the 
DSMB approves the changes. 
 
VOLUNTARY PARTICIPATION  
 
Your participation in this study is entirely voluntary.  Your decision not to 
participate will not have any negative effect on your medical care.  You can 
decide to participate now, but withdraw your consent later and you will stop being 
in the study without any loss of benefits or medical care to which you are entitled. 
 
DURATION OF STUDY INVOLVEMENT  
 
This research study is expected to take approximately 3 years.  After enrolling in 
this study, there is approximately 1 year of dose escalation visits followed by 
2 years of maintenance.  During the third year of the study, some subjects will be 
randomly assigned to a lower maintenance dose. 
 
PROCEDURES 
 
If you choose to participate, Dr. Nadeau, Dr. Chinthrajah, and/or the research 
study staff will ask you to sign this informed consent form.   
 
If you agree to take part in the study, you will be assigned to one of the two 
different study groups. You cannot choose which study group you will be 
assigned.  You will be assigned by chance, like flipping a coin, and will receive 
either the study treatment (peanut flour) or a placebo (oat flour).  You will be in 
this study for a total of about three years.  
 
The study includes five phases: 
• Screening (3 visits) 
• Initial Dose Escalation (1 visit)  
• Build-Up (clinic visits every 2 weeks for approximately 1 year) 
• Maintenance (clinic visits every 13 weeks for approximately 1 year) 
• Tolerance Testing (clinic visits every 13 weeks for approximately 1 year)

If you are enrolled in the study, the study staff will provide training concerning the 
following: 
• How to properly store and administer the study dose. 
• How to recognize allergic reactions and/or other adverse events. 
• What actions you must take should you demonstrate an allergic reaction 
and/or other adverse event. 
 
If at any time you have a question or concern, please contact the Protocol 
Director or other member of the study team immediately. 
 
Screening: 
You will be asked to come to the Stanford University Clinical Food Research Unit 
(CFRU) at El Camino Hospital.  You will be asked to stop antihistamines (for 
example Benadryl, Zyrtec, Allegra, or others) for a certain amount of time before 
the visit in order to undergo an Allergy Skin Prick Test and Oral Food Challenge 
(OFC).  You must be off oral corticosteroids (for example, Prednisone) at least 
one month before undergoing screening procedures. Before any of the OFC 
procedures, if your doctor thinks it is necessary, an IV catheter may be inserted 
into a vein in your arm in case medications are needed for treatment of a 
reaction. LMX cream, a medicine put on the skin to numb it, may be applied to 
the skin 15 minutes prior to IV placement to make it less painful. 
This visit will take approximately 3 hours. 
Then, the next two visits will be for double-blind placebo-controlled food 
challenges (DBPCFCs).  These visits will be conducted on 2 separate days and 
will each take approximately 8 hours.  On one day, you will eat peanut flour 
mixed in with another food, such as applesauce.  The other day, you will eat the 
placebo, oat flour.  Neither you nor the study staff working with you during the 
DBPCFCs will know what you are eating on that particular day. 
You will eat a series of increasing doses of peanut or placebo which will be 
administered every 15-30 minutes until a reaction is observed or the final dose is 
consumed.  During the peanut challenge, the total amount of allergen consumed 
is slightly more than 2 full peanuts. This screening challenge is being done to 
confirm your allergy to peanut. In order to be eligible, the study staff must see a 
reaction to the peanut challenge at a total dose of 500mg of peanut protein or 
less AND no reactions to the placebo challenge.  If you do not have a reaction to 
the peanut challenge or if you have a reaction or symptoms that stop the placebo 
challenge, you will not be eligible to continue in the study. 
 
If it is determined you are eligible for the study, you will be randomly assigned 
(like flipping a coin) to receive either peanut protein or placebo (oat flour) and you 
will return to the CFRU for the Initial Dose Escalation (IDE) Day.  The IDE Day 
must take place within 300 days of the Screening Visit described above.

Women of Childbearing Potential 
 
If you are a woman who is able to become pregnant, it is expected that you will 
use an effective method of birth control to prevent exposing a fetus to a 
potentially dangerous agent with unknown risk.  If you are pregnant or currently 
breast feeding, you may not participate in this study.  You understand that if you 
are pregnant, if you become pregnant, or if you are breast-feeding during this 
study, you or your child may be exposed to an unknown risk. 
 
To confirm to the extent medically possible that you are not pregnant, you agree 
to have pregnancy tests done before beginning this research study and during the 
course of the study. 
 
You must agree to avoid sexual intercourse or use a birth control method judged 
to be effective by the investigator and which will not interfere with the proposed 
investigation.  You must accept the risk that pregnancy could still result despite 
the responsible use of reliable method of birth control.  You agree to notify the 
investigator as soon as possible of any failure of proper use of your birth control 
method, or if you become pregnant, either of which may result in your being 
withdrawn from the study. 
 
Initial Dose Escalation Day: 
The Initial Dose Escalation will be done to determine the starting dose for the 
build-up phase of the study.  We will carefully feed you a small amount of peanut 
protein or placebo (oat protein) to observe for any reactions.   
The Initial Dose Escalation will start with 0.5 mg peanut protein/placebo given by 
mouth in a small amount of food, for example, applesauce. The amount of 
peanut protein or placebo given will approximately double every 15-30 minutes 
up to a maximum dose of 6 mg. You must tolerate a dose of at least 1.5 mg at 
the IDE to remain in the study.  Once the maximum tolerated dose is given, you 
will be observed for two hours. If there is no evidence of an allergic reaction, you 
will be sent home. This visit may last 8 hours or longer if you have a reaction to 
the peanut protein or placebo.   
If you do not have a current in-date epinephrine auto-injection device (for 
example, EpiPen, Jr™ or EpiPen™) at the beginning of the study, you will be 
given a prescription for one to have with you at all times.  The study staff will 
review how to use it, with you before you are sent home. The epinephrine will be 
used if there are any symptoms of a life-threatening allergic reaction which may 
include a rash, swelling, difficulty breathing, or vomiting.  You will be required to 
have your epinephrine auto-injection device with you at all times, including 
bringing it to your clinic visits.

Again, this is a double-blind study meaning that you and the study staff will not 
know if you will be receiving peanut protein or placebo.  However, if this 
information is needed for your safety in an emergency, the blind can and will be 
broken. 
After you begin dosing with peanut or placebo, you will be trained on how to 
complete a daily online “diary” at home to confirm that you took your dose, 
whether or not you had any allergic reactions to your dose, and whether or not 
you had any other changes in your health that the study staff needs to know 
about.  This diary is only available online through a secure website and must be 
completed every day that you are taking peanut or placebo doses as part of this 
study.

Build-Up: 
On the Initial Dose Escalation Day, you will be sent home with 2 weeks of home 
doses at the highest tolerated dose, which will be a minimum of 1.5 mg to 
maximum of 6 mg.   
 
The daily peanut protein or placebo dose will be taken by you, at home for 2 
weeks.  You will then be asked to return every 2 weeks to the site to have the 
dose of daily peanut protein or placebo increased as appropriate.  
 
The goal is to have you reach a daily peanut protein or placebo maintenance 
dose of 4,000 mg, every day without having an allergic reaction.  This is the 
amount of peanut protein found in approximately 17 peanuts.  The amount of

When you reach the maximum tolerated dose (up to 4,000 mg per day) during 
Build-Up phase, you will enter the Maintenance phase.   
 
The table below summarizes the procedures to be done at visits during the Build-
Up Phase.  Please remember that there may be visits after Week 44 (performed 
every 2 weeks) to increase your dose up to 4,000 mg daily. 
 
Changes to the Dose Escalation to try to improve safety: During dose 
escalation, we will ask you to drink more (about two full glasses of liquid) and to 
restrict exercise for about 2 hours after dosing.

Maintenance: 
You will continue on daily peanut protein or placebo during the Maintenance 
phase and you will be asked to return every 13 weeks for a blood draw and skin 
prick test.  Approximately 104 weeks following the Initial Dose Escalation Day, 
you will return for a visit that will include a blood draw, skin prick test, and a 
Double Blind Placebo Controlled Food Challenge (DBPCFCs) (one day to 
peanut, one day to placebo) up to 4,000 mg.  A blood draw and skin prick test will 
be performed on the first day of the DBPCFC.   
 
The table below summarizes the procedures to be done at visits during the

Tolerance Testing: 
After the DPBCFCs at Week 104, if you meet certain criteria, you will reduce your 
daily dosing either to 300 mg of peanut protein OR to 600 mg of placebo.  During 
this stage, you will return every 13 weeks for 4 more timepoints (until Week 156) 
for a blood draw, skin prick test, and DBPCFCs to 4,000 mg. Each DBPCFC visit 
entails 2 in-person visits that are 5-7 days apart;one day will be a placebo 
challenge and the other, peanut.  
 
If you do not meet the protocol specific criteria at Week 104, you will be 
considered a desensitization failure and may continue in the study or you will be 
offered a follow-up protocol at week 117 that is separate from this protocol.

Description of Procedures 
Allergy Skin Prick Testing: Skin testing involves putting drops of allergy 
extracts to food and environmental allergens on the forearm or back and lightly 
pricking the skin with a sterile lancet. If you are allergic to the allergy extracts, the 
results could be an itchy, raised bump and are usually apparent within 15 
minutes. 
 
Blood samples for research markers:  You will have blood drawn 
approximately every 12-13 weeks throughout the study.  Some tests will be done 
for safety and some tests will be done to look at how your immune system 
changes during the study. Each time blood is drawn, we will collect blood 
according to weight-based safety guidelines established by the National Institutes 
of Health (NIH).  When blood is collected, the minimum volume collected will be 
approximately 30 mL (2 tablespoons).  For children younger than 13, the 
maximum volume drawn could be up to 5 mL/kg.  For adults, the maximum 
amount will not exceed 500 mL. 
 
Research tests help us learn more about your disease, the immune system (the 
body’s natural defense system against illness), and response to drugs or 
treatment.  The results of the research tests will not be shared with you.  These 
research samples will not identify you by name, but will have a code.

Research tests will include genetic tests.  These laboratory tests study your 
inherited (present from birth) characteristics which are present in each of your 
cells.  
 
Genetic testing may help researchers learn more about allergic disease, or help 
to find treatments for allergy.  As with all research tests, these results will not be 
shared with you.    
 
Some of your blood samples may be sent outside of Stanford for analysis. 
 
Diet and Allergy Assessment:  During the study you will be asked to answer 
questions about your medical history, diet, and allergy symptoms you have 
experienced. 
 
IV Catheter Insertion:  For your safety, an IV catheter needle may be inserted 
into a vein in your arm before some visits in case medications are needed for 
treatment of a reaction. LMX cream, a medicine put on the skin to numb it, may 
be applied to the skin 15 minutes prior to IV placement to make it less painful. 
 
Initial Dose Escalation:  The initial dose escalation procedure begins with a 
very small amount of peanut protein or placebo (0.1 mg) given by mouth in a 
small amount of food. The amount of peanut protein or placebo given to you will 
approximately double every 15-30 minutes until 6 mg is given.  Once the 6 mg 
dose is given, you will be observed for two hours. If there is no evidence of an 
allergic reaction, you will be sent home. This visit may last 8 hours or longer if 
you have a reaction to the peanut protein or placebo.  
 
Double Blinded Placebo Controlled Food Challenge (500 mg and 4,000 mg):  
A DBPCFC consists of you eating both a food to which you may be allergic 
(peanut) and eating a placebo at different times. The peanut or placebo will be 
given in a “double-blinded” fashion under observation in the hospital clinic. 
“Double-blinding” means that neither the Protocol Director, nor the research 
team, nor you will know whether you are receiving peanut protein or placebo. 
However, in the case of an emergency, the study staff can quickly locate the 
information.  
You will be given peanut protein or placebo at about 15-45 minute intervals up to 
a maximum single dose of 125 mg or 1,050 mg, for a total cumulative dose of 
500 mg or 4,000 mg respectively, if you complete all of the doses and do not 
have an allergic reaction to one of the doses. If you have a reaction to one of the 
doses, the dosing of peanut protein or placebo will be stopped and the allergic 
reaction will be treated with appropriate medications to stop the reaction. The 
food challenge (500 mg and 4,000 mg) will happen over the course of 2 days. 
Changes to the Oral Food Challenge to try to improve safety: During oral 
food challenge, you will be asked to drink about two glasses of liquid, the interval

POSSIBLE RISKS, DISCOMFORTS, AND INCONVENIENCES  
 
Risk of allergic reactions: The daily peanut oral immunotherapy may cause 
allergic symptoms. Potential symptoms may include some or all of the following 
symptoms: sneezing, runny nose, flushing, swelling of the tongue/throat or lips, 
flares of eczema, nausea, vomiting, abdominal discomfort, itching, rash/hives, 
swelling, wheezing or difficulty breathing, fainting or becoming lethargic or weak. 
Allergic reactions are usually mild but may occasionally be moderate or severe.  
 
A very serious allergic reaction called anaphylaxis has been known to occur with 
rapid flushing/itching, more severe wheezing or difficulty breathing, swelling of 
the throat, and/or drop in blood pressure.  Sometimes, this reaction can result in 
death.  In order to lessen the likelihood of you experiencing any allergic 
symptoms, dosing of peanut protein will be initiated at extremely small amounts. 
Participants will be closely observed in the clinic for at least 2 hours, before being 
discharged to watch for these signs or symptoms.  Doctors and nurses trained in 
these kinds of reactions will be present and emergency equipment will be 
available if treatment is necessary.   
 
There may be an increased risk of developing Eosinophilic esophagitis (EoE), 
which is an immune-mediated disease as a result of inflammation of the 
esophagus. Symptoms range by age, with children potentially presenting with 
feeding difficulties, abdominal pain, and/or vomiting and adults may experience 
chest pain, food getting “stuck”, and/or abdominal pain. If these symptoms 
present, an endoscopy will be needed to confirm diagnosis, which may be 
performed by a gastroenterologist.   
 
Vigorous exercise is not permitted for at least 2 hours after the dose of oral 
allergen immunotherapy.  Also, there must be at least 1 hour between vigorous 
exercise and taking a dose of oral allergen immunotherapy.  Allergic reactions 
are still possible when exercise takes place more than 2 hours after the dose. 
 
Allergy Skin Prick Testing:  The risk involved with skin testing includes 
discomfort from the needle prick, along with itching and swelling at the skin test 
site in positive responses. Less common side effects include severe allergic 
reactions, as described above. 
 
Blood Tests/IV Catheter Insertion: This study includes the following risk or 
discomforts associated with blood draws including the risk of fainting, local pain, 
stinging, bleeding, or bruising at the site where the needle is inserted into the 
vein. On rare occasions infection at the needle stick site may occur.  Insertion of

an IV can cause a temporary burning feeling, bruising, or, on rare occasions, 
infection at the needle stick site. 
 
Oral Food Challenges 
Again, as described above, a potential risk associated with oral food challenge is 
the risk of a severe allergic reaction, called anaphylaxis.  Symptoms of 
anaphylaxis (severe allergic reaction) may include itchy rash, hives, facial 
swelling, swelling of throat, wheezing, cough, shortness of breath, vomiting, 
diarrhea, and in severe cases low blood pressure, loss of consciousness, 
hospitalization, and, rarely, death. After the tolerance testing period of the 
protocol, there is a risk of reacting to the food challenge.  As stated above, 
medication, personnel, and equipment are immediately available in the event of 
an anaphylactic reaction.   
 
POTENTIAL BENEFITS                              
 
If you agree to take part in this study, there may be no direct medical benefit to 
you.  It is hoped that the results of this study will help the investigators plan future 
studies in individuals that have allergy to peanut or other common allergies (egg, 
milk, wheat, etc.). 
We cannot and do not guarantee or promise that you will 
receive any benefits from this study. 
 
ALTERNATIVES 
 
The alternative to participating is to continue with routine medical care for your 
peanut allergy. 
 
PARTICIPANT’S RIGHTS 
 
You should not feel obligated to agree to participate.  Your questions should be 
answered clearly and to your satisfaction.  If you decide not to participate, tell the 
Protocol Director.

CONFIDENTIALITY 
 
Your identity will be kept as confidential as possible as required by law.  Your 
personal health information related to this study may be disclosed as authorized 
by you.  Your research records may be disclosed outside of Stanford, but in this 
case, they will be identified only by a unique code number.  Information about the 
code will be kept in a secure location and access limited to research study 
personnel.   
 
The results of this research study may be presented at scientific or medical 
meetings or published in scientific journals.  However, your identity will not be 
disclosed.  
 
Patient information may be provided to Federal and other regulatory agencies as 
required.  The Food and Drug Administration (FDA), for example, may inspect 
research records and learn your identity if this study falls within its jurisdiction. 
 
You will be identified by a study code, not your name.  The key to the code is 
kept in a secured file at the study site.  Personal data from your records will not 
be released without your written permission.  You will not be named in any 
publication about this study.   After the study is completed, the study data may be 
placed in a central storage location.  The purpose is to make study data available 
to other researchers who must request permission from National Institute of 
Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health 
(NIH).  This data does not include names of any of the participants and your 
privacy is protected whenever this data is used.     
 
Medical and research records from this study will be reviewed by the United 
States agency funding this study (the National Institute of Allergy and Infectious 
Diseases), including its, representatives, agents, employees, contractors, and 
other persons assisting in conducting, monitoring or analyzing the study.  In 
addition, the U.S. Food and Drug Administration (FDA), or other health

Stored Samples and Information: 
If you agree, we will store your remaining samples and information in a central 
location.  The purpose is to make these samples and information available for 
future research which is not yet planned.  
 
Your decision to allow your remaining samples and data to be stored is separate 
from your decision to participate in this study.  If you decide to allow storage, 
your samples and data may be stored for an indefinite length of time.  No 
additional samples for storage are taken.  Remaining samples are stored when 
all other study required tests are completed.  Your samples may be sent outside 
of Stanford for analysis.  
   
The results of tests done on your stored samples will not be given to you or your 
doctor.  The results will not be put in your records and will not change your 
medical care. There will be no benefits to you from the storage of these samples 
and information.  However, the use of your samples and information may help 
researchers learn more about your disease or help study the genetics related to 
your disease.   
 
There may be risks in allowing the storage or analysis of samples and 
information. For example, if future research is for genetic testing and because 
genetic information is unique to you there is a risk that someone could trace it 
back to you.  Researchers are required to protect your privacy and to keep you 
and your information private to the extent permitted by the law.  
 
The samples and information will not be sold; however, the results of the tests 
could lead to the development of commercial products.  You will not receive any 
money from research using your stored samples and information.    
   
Sometimes patients have been required to furnish information from genetic 
testing for health insurance, life insurance, and/or a job.  A Federal law, the 
Genetic Information Nondiscrimination Act of 2008 (GINA), generally makes it 
illegal for health insurance companies, group health plans, and employers with 
15 or more employees to discriminate against you based on your genetic 
information. 
 
You can change your mind at any time during the study and ask to have your 
samples destroyed.  This request should be made in writing to the Protocol 
Director.  If your samples have not been used, they will be destroyed.  If your 
samples have already been tested before your request, the information from 
these tests will be used and cannot be destroyed.

Authorization To Use Your Health Information For Research 
Purposes  
Because information about you and your health is personal and 
private, it generally cannot be used in this research study without 
your written authorization.  If you sign this form, it will provide that 
authorization.  The form is intended to inform you about how your 
health information will be used or disclosed in the study.  Your 
information will only be used in accordance with this authorization 
form and the informed consent form and as required or allowed by 
law.  Please read it carefully before signing it.   
 
What is the purpose of this research study and how will my 
health information be utilized in the study? 
This is a research study to learn about the medical effects, the safety, 
and the immunologic effects of Peanut Oral Immunotherapy (OIT) 
treatment.  A total of 120 people between the ages of 7 and 55 years 
old will be asked to take part in this study at Stanford University.  The 
goal of the study is to find out whether subjects can develop the

Investigational 
Product(s)/Intervention(s) 
Investigational Product: Peanut Flour 
Interventions:  
• 
Medical and allergy history (including dietary history) 
• 
Physical assessment 
• 
Spirometry  
• 
Serum or urine pregnancy tests 
• 
Plasma analysis for IgE and IgG4 to peanut (UniCAPTM) 
• 
Oral food challenge to peanut 
• 
Skin prick test  
• 
Study product administration 
• 
Initial Dose Escalation Day Oral Immunotherapy (OIT) 
• 
Build up and maintenance OIT 
Study Objectives 
Primary Objective: 
Determine whether peanut oral immunotherapy induces clinical 
tolerance as assessed after the initial 3 month avoidance period  
 
Secondary Objectives: 
• 
Identify the basic immune mechanisms which can explain the 
differences in the effects of OIT in desensitized vs. tolerant 
individuals. 
• 
Determine whether immune monitoring measurements 
reflecting underlying mechanisms during OIT can be used to 
predict responses to OIT in individual subjects and, ultimately, to 
improve the safety and efficacy outcomes in peanut OIT 
protocols. 
Study Design 
A Phase 2, single-center, randomized, double blind, placebo controlled 
study of the induction of peanut tolerance by oral immunotherapy (OIT). 
Our intent to treat population will be 120 subjects, ages 7-55 years, with 
an allergy to peanut, as determined by DBPCFC, history, clinical 


4 
 
symptoms, and positive skin prick test (SPT). The 120 enrolled subjects 
will be randomized 2.4:1.4:1. Thus, there will be three arms: (1) Arm A on 
peanut OIT until week 104 and once meeting criteria [i.e.  1) assigned to 
OIT treatment for minimum 104 weeks, 2) reaching maintenance 13 
weeks prior to DBPCFC at week 104, 3) no severe reactions (Grade 3, 
APPENDIX 4) to home dosing from Week 92-Week 104, and/or 4) no 
objective reactions, (Appendix 4) at the Week 104 DBPCFC]  has been 
assigned to avoid peanut (i.e. 600 mg oat flour). (2) Arm B on peanut OIT 
until week 104 and once meeting criteria, has been assigned to be 
maintained on 300 mg peanut protein (i.e. 600 mg peanut flour). (3) Arm 
C that is maintained on placebo (oat flour) and once meeting criteria, will 
receive 600 mg oat flour beginning on week 104. This will be true even if 
a subject in the placebo group meets criteria at week 104. This way all 
participants will receive approximately the same volume of flour so that 
the subject blinding will be easier to maintain. The decision to maintain 
subjects on only 300 mg peanut protein after week 104 is for ease of 
eating peanut and to test if a lower amount of protein can still maintain 
desensitization.   
After week 104, subjects will then be rechallenged every 3 months for a 
year. Individuals will be defined as “clinically tolerant” if there is no 
clinical reactivity upon rechallenge. Clinical reactivity is defined as any 
objective reaction based on the Bock’s Criteria (Appendix 4).  
We plan to identify the basic immune mechanisms which can explain the 
differences in the effects of OIT in individuals who do or do not become 
tolerant and to determine whether immune monitoring can predict the 
safety and efficacy outcomes in peanut OIT protocols. 
 
Subjects will also be asked via a separate sub-study and consent which 
will look at biopsies from the gastrointestinal tract to show different 
markers at week 52, 104 and week 117 (or equivalent, with "or 
equivalent" meaning in this context that the visit may not be scheduled 
exactly in week 117, given such factors as the subject's schedule, etc…) 
compared to baseline. In addition, we will determine whether there are 
trends for differences in the markers detected in GI tissues in placebo vs 
avoidance vs treatment arms. 
 
Primary Endpoint(s) 
Proportion of peanut allergic subjects who pass a DBPCFC after the 
3 month avoidance period (Week 117 or equivalent) following the 
end of active treatment phase 
 
Secondary Endpoint(s)  
1. Proportion of PA subjects who pass a DBPCFC after a 6 month 
avoidance period. 
2. Proportion of PA subjects who pass a DBPCFC after a 9 month 
avoidance period. 
3. Proportion of PA subjects who pass a DBPCFC after a 12 month 
avoidance period. 


5 
 
4.Proportion of PA subjects who can successfully complete the 
build-up phase of peanut OIT to the highest dose (4,000 mg of 
peanut protein) with only mild (objective, APPENDIX 4) symptoms 
related to dosing. 
5. Proportion of PA subjects who can successfully undergo the 
build-up and maintenance phases of peanut OIT with only mild 
symptoms. 
6. Comparison of the proportion of subjects in placebo, avoidance, 
and 300 mg peanut protein groups who are able to undergo OFCs 
with no clinical reactivity after initiating OIT. 
 
Sub Study GI Endpoint 
Proportion of PA subjects who show increased immune cells consistent 
with immune tolerance (i.e. regulatory T cells) vs. inflammatory allergy 
(i.e. eosinophils, mast cells) over time points obtained with GI biopsy 
tissues. 
 
Accrual Objective 
120 
Study Duration 
This is a 5 year study. Participants will be in an active phase of the 
protocol for 3 years (see Appendix 1 for individual subject 
timeline); long term follow-up will be conducted but not beyond 
the 5 years of the grant. 
Treatment Description  
Subjects will undergo an Initial Dose Escalation Day to 
consumption of maximum single dose of 6 mg peanut/placebo 
protein.  They will consume this dose at home for two weeks and 
document reactions.  Upon returning to the CFRU (Clinical Food 
Research Unit) two weeks later, a dose escalation will be 
attempted.  This cycle will continue until the subject reaches a 
maximum dose of 4,000 mg peanut/placebo protein daily.   There 
will be three arms: (1) Arm A on peanut OIT until week 104 and once 
meeting criteria [i.e.  1) assigned to OIT treatment for minimum 104 
weeks, 2) reaching maintenance 13 weeks prior to DBPCFC at week 104 3) 
no severe reactions (Grade 3, APPENDIX 4) to home dosing from Week 92-
Week 104, and/or 4) no objective reactions, (Appendix 4) at the Week 104 
DBPCFC]   has been assigned to avoid peanut (i.e. 600 mg oat flour). (2) 
Arm B on peanut OIT until week 104 and once meeting criteria, has been 
assigned to be maintained on 300 mg peanut protein (i.e. 600 mg peanut 
flour). (3) Arm C that is maintained on placebo (oat flour) and once 
meeting criteria, will receive 600 mg oat flour beginning on week 104. 
This will be true even if a subject in the placebo group meets criteria at 
week 104.This way all participants will receive approximately the same 
volume of flour so that the subject blinding will be easier to maintain. The 
decision to maintain subjects on only 300 mg peanut protein after week 
104 is for ease of eating peanut and to test if a lower amount of protein 
can still maintain desensitization.

1. Background and Rationale  
1.1. Background and Scientific Rationale  
Few studies have been conducted to optimize safety and to identify the immunological mechanism(s) underlying any 
long-lasting effects of oral immunotherapy (OIT). Specifically, it is not yet clear what factors will determine, in an 
individual subject, whether OIT has induced tolerance (in which he or she can safely ingest peanut ad lib without the 
need for daily consumption of peanut).1, 2 To address these challenges in the field of food allergy research, the Stanford 
Alliance for Food Allergy Research (SAFAR) proposes to link the findings of this current clinical study to mechanistic 
studies (proposed as distinct projects under the same  AADCRC study). This current clinical study (n=95 OIT and 
n=25 placebo conducted over 5 years in subjects 7-55 years of age with peanut allergies), together with the three 
mechanistic-based research projects (Section 9), presents a unique opportunity to create a comprehensive dataset 
combining the clinical outcomes of the OIT protocol with the results of innovative studies of tolerance in order to better 
understand mechanisms of OIT and to improve the safety and efficacy of oral immunotherapy of peanut allergy (PA). 
There have been reports of success in a small number of mostly pediatric (under 18 years) patients in which oral food 
allergen immunotherapy has achieved desensitization (i.e. clinical non-reactivity to ingestion of a known allergen that 
must be maintained by daily consumption of that allergen) for milk1,4,5, egg6,7, and peanut8-25. The protocols for such 
trials are varied, involving rush therapy phases, weekly increases in doses, or both. In our first Phase 1 peanut oral 
immunotherapy (OIT) study conducted at Stanford from July 2009 to present, we focused on the safety parameters of 
peanut OIT in children and adults. Since the incidence and prevalence of food allergies in adults and children are rising 
(http://www.foodallergy.org/files/FoodAllergyFactsandStatistics.pdf) it is important to be able to understand the 
therapeutic and mechanistic effects of food allergy oral immunotherapy in both populations. We recently published our 
safety findings on some subjects in the Phase 1 peanut OIT study3.  All subjects are tolerating peanut at increasing doses. 
Twenty (20) subjects were given placebo OIT in our study, which is important to evaluate the rate of spontaneous 
remission of peanut allergy and to compare safety profiles between the OIT and placebo groups. In addition, 16 of the 
current peanut OIT subjects have been tested for tolerance; 6 have become “immune tolerant” (referred to herein as 
“tolerant”) (i.e., they can eat peanut with no clinical reaction after a period of avoidance from peanut OIT—in the case 
of our subjects to date, 3 months); by contrast, 10 have not become tolerant to peanut (i.e., they developed a clinical 
reaction to peanut challenge after a period of avoidance from peanut OIT).  
Our proposal, representing a new clinical study of OIT in adult and pediatric subjects with PA, is designed to provide data 
that can help identify mechanisms in the development of immune tolerance and improve the safety of future OIT 
studies. The new protocol proposed here will enroll different patients from those already studied at Stanford and will 
differ from our Phase 1 study (Syed, American Academy of Asthma, Allergy and Immunology Conference, San Antonio, 
TX, 2013) and from that of others since:  1) the patients will include both adults and children; 2) subjects will have the 
opportunity to be tested for immune tolerance during longer intervals of peanut avoidance; 3) we will perform 
sophisticated tests to discriminate clinically between tolerance and lack of tolerance; and 4) we will perform basic 
science studies on immune indicators in an attempt to identify those tests that are useful for allowing the safe and 
efficacious dosing of individual PA subjects during OIT and/or for discriminating between those patients who do or do 
not develop tolerance as a result of OIT.  
In a separate substudy of 20 subjects, we will look at biopsy samples from the gastrointestinal tract of participants who 
have enrolled in the main study.  Allergic disorders of the gastrointestinal tract are characterized by infiltration of the 
mucosal lining with inflammatory cells, such as eosinophils. These disorders include eosinophilic gastroenteritis, 
esophagitis and colitis. Patients with these disorders often have a history of allergy, including a high IgE level, peripheral 
eosinophils and allergic disease (such as food allergies or allergic rhinitis).  This will help with our understanding of 
possible associations with eosinophilic disease and oral immunotherapy, with tolerance markers in the local organ vs 
peripheral blood and how it affects the local tissue in the GI tract over time. We will explore whether the 20 participants 
with GI biopsies show different markers at week 52 vs. week 104 vs. week 117 (or equivalent) vs. baseline. In addition, we 
will determine whether there are trends for differences in the markers detected in GI tissues in placebo vs avoidance vs 
treatment arms. The procedures to find these markers include immunohistochemistry to identify cells-inflammatory and 
regulatory (mast cells, basophils, eosinophils, T cells, B cells, dendritic cells, and epithelial cells and associated markers –


15 
 
for example  TSLP, IL-33, IL-18, IL-10 ,  CD103, IL-4, IL-13, histamine, STAT6, GATA3, T-bet, IFN-g, TGF-b), single cell 
sorting with RNA Seq, and cryopreservation for future analysis outside the scope of the proposal. 
At the biopsy level, we anticipate that subjects will have increased IL-4/IL-13/IL-5 in T cells, and increased mast cells and 
eosinophils at baseline, and that, over time, they will have decreases in IL-4/IL-13/IL-5 in T cells, mast cells, eosinophils 
and increases in Treg and interferon gamma secreting T effector cells at the local tissue level over time at week 52, week 
104 and week 117 (or equivalent).  Samples will be read by a trained Pathologist and results will be available within one 
week. If changes indicate EoE, participants will be referred to our gastroenterology clinics and will discontinue the study. 
 We also expect increases in tolerogenic DCs overtime (i.e. increases in CD103).  Overall, we think that this study will be 
the first of its kind to examine the local tissue of the GI tract during immunotherapy in food allergy and this is an 
exploratory study to be able to move forward with further hypothesis testing on future trials. 
 
 
1.2. Rationale for Selection of Investigational Product or Intervention 
The rationale for dosing builds on the work of the Consortium of Food Allergy Research (CoFAR), a Stanford Phase 1 
study, and other studies by Dr. Burks (University of North Carolina) and Dr. Jones (University of Arkansas). The dosing 
consists of a single-day initial escalation at very low doses, followed by a build-up phase of increasing doses, occurring 
every 2 weeks. This has been demonstrated to be well tolerated and efficacious in previous studies and will be used in 
this current trial.  
1.3. Preclinical Experience 
n/a 
1.4. Clinical Studies 
Recently, Dr. Wesley Burks presented work showing that 10 children with PA completed an OIT protocol and underwent 
an oral food challenge (OFC) 4 weeks after cessation of oral intake of peanut to evaluate for the possibility of clinical 
tolerance (Vickery, et al., American Academy of Allergy, Asthma, and Immunology National Conference. Orlando, 
Florida, March 6, 2012). Three (3) out of 10 subjects passed the OFC; the authors considered these subjects clinically 
tolerant. Over the course of treatment, peanut IgE levels lower than 85 kU/L at a time point of 3 months into OIT was 
predictive of subjects who became immune tolerant. These initial findings, along with our preliminary data, are 
provocative and require further studies to be conducted to evaluate the reproducibility of the results obtained in this 
small group of children, to extend the work to adults with PA, and also to document the duration of the clinical lack of 
reactivity to peanut achieved in such subjects. A recent review by Byrne, et al. succinctly asks a key question: “How do 
we know when peanut and tree nut allergy have resolved, and how do we keep it resolved?”26 
2. Study Hypotheses/Objectives 
2.1. Hypotheses 
Our hypothesis is that peanut immunotherapy will induce changes in subject’s cellular and humoral immune system and 
thus make them less allergic to peanut allergens.  
2.2. Primary Objective(s) of the overall research program 
Determine whether peanut oral immunotherapy induces clinical tolerance as assessed after the initial 3 month 
peanut avoidance period  
2.3.  Secondary Objective(s) of the overall research program 
• 
Identify the basic immune mechanisms which can explain the differences in the effects of OIT in desensitized vs. 
tolerant individuals.  


16 
 
• 
Determine whether immune monitoring measurements reflecting underlying mechanisms during OIT can be 
used to predict responses to OIT in individual subjects and, ultimately, to improve the safety and efficacy 
outcomes in peanut OIT protocols.

* The 120 enrolled subjects will be randomized 2.4:1.4:1 (please see section 13). Thus, there will be three arms: 
(1) Arm A on peanut OIT until week 104 and once meeting criteria [i.e.  1) on OIT treatment for minimum 104 weeks, 
2) taking daily maintenance dose of 4,000 mg protein for at least 13 weeks, 3) no severe reactions (Grade 3, APPENDIX 4) to 
home dosing from Week 92-Week 104, and/or 4) no objective reactions, (Appendix 4) at the Week 104 DBPCFC]   has been 
assigned to avoid peanut (i.e. 600 mg oat flour). (2) Arm B on peanut OIT until week 104 and once meeting 
criteria, has been assigned to be maintained on 300 mg peanut protein (i.e. 600 mg peanut flour). (3) Arm C that 
is maintained on placebo (oat flour) and once meeting criteria, this arm will receive 600 mg oat flour beginning 
on week 104. This will be true even if a subject in the placebo group meets criteria at week 104. This way all 
participants will receive approximately the same volume of flour so that the subject blinding will be easier to 
maintain. The decision to maintain subjects on only 300 mg peanut protein after week 104 is for ease of eating 
peanut and to test if a lower amount of protein can still maintain desensitization.   
3. Study Design 
3.1. Description of Study Design  
A Phase 2, single-center, randomized double blind, placebo controlled study of the induction of peanut tolerance by oral 
immunotherapy (OIT). Our intent to treat population will be 120 subjects, ages 7-55 years, with an allergy to peanut, as 
determined by DBPCFC, history, clinical symptoms, and positive skin prick test (SPT). Please see Figure 1.

First, subjects will be screened (Part I, Figure 1). The 120 enrolled subjects will be randomized 2.4:1.4:1 (please see 
section 13). Thus, there will be three arms: (1) Arm A on peanut OIT until week 104 and once meeting criteria [i.e.  1) on 
OIT treatment for minimum 104 weeks, 2) taking daily maintenance dose of 4,000 mg protein for at least 13 weeks, 3) no severe 
reactions (Grade 3, APPENDIX 4) to home dosing from Week 92-Week 104, and/or 4) no objective reactions, (Appendix 4) at the 
Week 104 DBPCFC] has been assigned to avoid peanut (i.e. 600 mg oat flour). (2) Arm B on peanut OIT until week 104 and 
once meeting criteria, has been assigned to be maintained on 300 mg peanut protein (i.e. 600 mg peanut flour). (3) Arm 
C that is maintained on placebo (oat flour) and once meeting criteria, will receive 600 mg oat flour beginning on week 
104. This will be true even if a subject in the placebo group meets criteria at week 104. This way all participants will 
receive approximately the same volume of flour so that the subject blinding will be easier to maintain. The decision to 
maintain subjects on only 300 mg peanut protein after week 104 is for ease of eating peanut and to test if a lower amount 
of protein can still maintain desensitization.  This upfront randomization is performed because our statistical analysis plan is 
focused on an intent to treat analysis.     
All arms will undergo an Initial Dose Escalation (IDE) Day and updosing regimen with a maintenance phase of OIT or 
placebo to a maximum of 4,000 mg protein daily, as peanut flour, in the OIT groups, and to a maximum of an equivalent 
amount of oat flour for the placebo group). (Part III, Figure 1).  After maintenance is achieved, all subjects will begin 
performing DBPCFCs (staged so as to ensure safety) at Week 104 and every 13 weeks thereafter (Part IV, Figure 1).  At 
Week 104, individuals that reach criteria (Part IV, Figure 1) will, based on the randomization that was done at the start of 
the study, either stop therapy with peanut and be switched to oat flour, or will be maintained on 300 mg peanut protein 
per day (Parts V, Figure 1). If subjects fail the week 104 DBPCFC they will not be given home doses. Those that fail the 
week 104 FC will remain in the study and return for a study completion visit at week 117 to meet the primary endpoint 
(will be analyzed in the intent to treat comparisons). All subjects will be evaluated every 13 weeks thereafter until the 
end of study.   
Individuals in Arm A will be defined as “clinically tolerant” if there is no clinical reactivity at the Week 104 and Week 117 
(or equivalent) DBPCFC. Clinical reactivity is defined as any objective reaction based on the Bock’s Criteria (Appendix 4).  
Individuals in Arm A who meet the definition of “clinically tolerant” will continue to avoid peanut protein (i.e. continue 
on 600 mg per day of oat flour) as long as each subsequent DBPCFC (performed every 13 weeks until end of study) 
shows no clinical reactivity. 
Individuals in Arm B will be defined as “desensitized” to a minimum of 300 mg per day of peanut protein if they show no 
clinical reactivity at DBPCFCs (week 117 (or equivalent) to end of study). 
Individuals in Arm C will be defined as “natural loss of responsiveness” if they show no clinical reactivity at DBPCFCs 
(week 117 (or equivalent) to end of study). 
We plan to identify the basic immune mechanisms which can explain the differences in the effects of OIT in individuals 
who do or do not become clinically tolerant and to determine whether immune monitoring can predict the safety and 
efficacy outcomes in peanut OIT protocols.  After initial screening and enrollment, there are three phases of the study:  
• 
Dose escalation and Build up Phase (Part III, Figure 1)  
• 
Maintenance phase  (Part IV, Figure 1) 
• 
Tolerance and Desensitization Testing phase (Part V, Figure 1) 
Overall, 120 subjects who are eligible will undergo the Initial Dose Escalation Day.  Subsequent updosing visits will occur 
every 2 weeks as a part of the build-up phase. They will continue to updose until they reach 4,000 mg protein daily, 
which is the maximum maintenance amount of protein. We expect active OIT treatment subjects to reach 4,000 mg of 
peanut protein between 44-78 weeks. 
GI Sub Study. 


19 
 
Subjects will also have the opportunity to participate in this study via a separate consent after they have enrolled in the 
study and prior to starting IDED at week 0.  
Treatment and Desensitization Failures: 
A treatment failure will be defined as a) failure to reach 1.5 mg peanut protein (single dose) during the Initial Dose 
Escalation Day or b) failure to reach 1,000 mg peanut protein by week 104.  
Subjects who do not meet the criteria (Part IV, Figure 1) at Week 104 and who demonstrate clinical reactivity (objective, 
Appendix 4) will be considered desensitization failures.  
If Arm B subjects demonstrate clinical reactivity (objective, Appendix 4) in any DBPCFC from Week 117 (or equivalent) to 
end of study, they will be considered desensitization failures.  
If Arm A subjects demonstrate clinical reactivity (objective, Appendix 4) in any DBPCFC from Week 117 (or equivalent) to 
end of study, they will be considered tolerance failures.  
Research staff may be unblinded when the primary endpoint (at the completion of the week 117 visit) is reached for the 
study. Treatment failures, desensitization failures, and tolerance failures may be unblinded (both participant and 
research staff) at week 117 and/or may be followed until the end of the study at the specified study visits (Appendix 1, 
Schedule of Events, early completion visit).  They will be considered in statistical analyses of the intent-to-treat 
population. 
 
Integration with mechanistic science program: We will use blood samples and clinical outcome measurements from this 
study to identify specific features of the immune response that are associated with ”clinical tolerance” at week 104, 117 
(or equivalent), 130, 143, and 156. . We will also determine special immune features associated with subjects who are 
desensitized at week 104, 117 (or equivalent), 130, 143, and 156. It will be important to compare any of the immune 
features to those of the placebo arm, treatment failures, and desensitization failures.  Treatment groups A, B, and C are 
key cohorts to be able to identify possible quantitative and/or qualitative differences in immune phenotypic features 
among subjects in the tolerance, desensitization, and placebo groups, since such information is critical to our efforts to 
identify possible differences in the mechanisms that underlie immune tolerance vs. desensitization. 
Study Design Safety Considerations 
The design considers important safety issues: 
• 
All updosing visits will be supervised in a hospital setting where trained study physicians are available within 60 
seconds 
• 
Standing orders from an MD are provided for all clinical study personnel (RN, NP, PA, etc.) to initiate treatment 
of reactions immediately (i.e., prior to MD notification), including IM administration of epinephrine, based on 
their own clinical judgment.  
• 
A crash cart with pediatric and adult equipment is available in close proximity (within 50 feet) of all patient 
hospital rooms 
• 
A code team is available for pediatric and adult patients 
• 
The peanut OIT will only escalate to a maximum 6 mg single dose during the initial dose escalation Day  
• 
Dosing symptoms and adverse events will be captured throughout the study 
• 
Subjects will be prescribed an epinephrine auto-injector (if not prescribed by a treating clinician previous to 
study entry) and all subjects will be trained in its use 
Subjects will be cautioned against consuming any peanuts or peanut-containing foods other than study-supplied food 
allergen while on study. 
3.2. Primary Endpoint

cells) vs inflammatory allergy (i.e. eosinophils, mast cells) over time points obtained with GI biopsy tissues. 
 
3.4. Stratification, Randomization, and Blinding/Masking 
Randomization will occur in a 2 by 2 block design performed by Dr. Turnbull using a computerized system. 
3.4.1. Procedure for Unblinding/Unmasking 
Unblinding must be approved by the study NIAID Medical Monitor unless an immediate life-threatening 
condition has developed and the NIAID Medical Monitor is not accessible.  In all cases of unblinding, the site 
investigator will notify the NIAID Medical Monitor within 24 hours.  The emergency unblinding will also be 
reported to the Data and Safety Monitoring Board (DSMB). 
A full account of the event will be recorded, including the date and time of the unblinding, the reason for the 
decision to unblind, and the name of the individual who made the decision and the names of the Medical 
Monitor and others who were notified.  
Unblinding the study due to an approved interim analysis, final analysis, or study termination will require written 
approval from NIAID. 
3.5.2 
Securing Blinding and Randomization Information 
Randomization lists are maintained in a secured area, the pharmacy, by the individuals responsible for maintaining 
the blind, the unblinded pharmacists. The PPD site monitor (Clinical Research Associate) inspects the lists at each 
site visit to ensure they remain in the secured pharmacy, only accessible by the unblinded pharmacists. In the case 
of unscheduled unblinding or the removal of the randomization lists from the secured pharmacy binder, the 
Clinical Research Associate will verify that the site Principal Investigator and the NIAID Medical Monitor have been 
notified and that a written account has been completed and forwarded to these individuals. 
4. Selection of Participants and Clinical Sites/Laboratories 
4.1. Rationale for Study Population 
The lower cutoff of 7 years of age was selected to include only subjects with sufficient blood volumes (to perform the 
mechanistic studies we need blood every 3 months or per schedule of events (+ or - 1 clinic visit).  We have included a 
weight cut off of 17 kg so that we are compliant with IRB and NIH guideline—i.e. (for children: 5 ml/kg at any single 
draw, no more than 9.5 ml/kg over an 8-week period; adults: the smaller of 10.5 ml/kg or 550 ml total at any single draw  
). The upper age limit of 55 years was selected to ensure that the patients do not have underlying cardiovascular 
conditions that could preclude the use of epinephrine in subjects exposed to the risk of anaphylaxis. 


21 
 
Cross-reactivity between peanut and grass pollen may affect the SPTs performed to peanut.  All subjects will be 
screened for appropriate environmental allergen sensitivity by SPT.

interpretation of the data obtained from the study.  
5. Known and Potential Risks and Benefits to Participants 
5.1. Risks of Investigational Product or Intervention as cited in Investigator Brochure or Package 
Insert 
There is no IB or Package Insert for the peanut flour.  
5.2. Risks of Investigational Product or Intervention cited in Medical Literature and/or those based 
on the Investigators’ experience 
In patients with peanut allergy, there have been many oral immunotherapy studies performed using procedures and 
dosing similar to those proposed in this Phase 2 study. In general, safety profile has been very good across the studies, 
and based on those studies approximately 80%, 15% and <1% of the subjects are expected to have a mild, moderate or 
severe symptoms, respectively, during some point in their dosing with the peanut immunotherapy. It is important to 
note that essentially all adverse events have been allergy-related, predictable, and reversible. The only major atypical 
adverse event has been several reported cases of eosinophilic esophagitis, reversible upon cessation of dosing. 
Specifically, the buildup and daily maintenance doses of peanut OIT may cause allergic symptoms including sneezing, 
rhinorrhea, urticaria, angioedema, flushing, flares of eczema, ocular, nasal, oral and/or throat pruritus, nausea, vomiting, 
abdominal discomfort, cough, wheezing and/or shortness of breath in addition to severe anaphylaxis.  Although no 
subject will be allowed to enroll who carries the diagnosis of eosinophilic disorder, the risk of eosinophilic esophagitis 
during OIT will be evaluated during the study37-38. The likelihood of a subject experiencing any allergic symptoms is 
expected to be lessened by initiating dosing at extremely small amounts of characterized peanut allergen and by buildup 
dosing under observation in a clinical setting until the maintenance dose is achieved. 
Oral food challenges may induce an allergic response.  Allergic reactions can be severe including life-threatening allergic 
reactions; however, the risk of an allergic reaction is reduced by initiating the challenge with a very small amount of the 
food, gradually increasing the dose, and stopping the challenge at the first sign of a reaction.  If subjects have an allergic 
reaction during the challenges, they may need oral, intramuscular, or intravenous medications.  Subjects will have an IV 
catheter placed before the OFCs if they have a history of anaphylaxis with hypotension requiring IV fluid resuscitation.  
Additionally, IV catheters may be placed, at physician discretion for any visit, based on factors such as previous 
reactions, recent clinical history, and clinical status observed at the visit.   Trained personnel, including a study physician, 


23 
 
as well as medications and equipment, will be immediately available to treat any reaction.  The anticipated rate of life 
threatening anaphylactic reactions would be < 0.1%. 
There may be a risk that during participation in the trial the subjects may decrease their vigilance against accidental 
peanut ingestion because they believe they are protected from it. This phenomenon has been reported in previous 
trials, and subjects in the trial will be warned that they should continue to practice their usual vigilance against 
accidental ingestion of peanuts or peanut-containing foods.   
5.3. Risks of Other Protocol Specified Medications 
Anti H-1 blockers (e.g., cetirizine, loratadine, fexofenadine) will be used orally according to manufacturer’s instructions 
approximately one hour prior to each food allergen dose at home.  The risks of these medications include:  
 
• 
Central nervous system: Headache, fatigue, somnolence, drowsiness, insomnia, sleep disorders, dizziness, 
muscle pain 
• 
Gastrointestinal: Diarrhea, nausea, vomiting, dyspepsia, abdominal pain, dry mouth 
• 
Neuromuscular & skeletal: Myalgia, back pain, pain in extremities 
• 
Hypersensitivity reactions (anaphylaxis, angioedema, chest tightness, dyspnea, flushing, pruritus, rash, urticaria) 
5.4. Risks of Study Procedures  
A potential risk associated with the Initial Dose Escalation Day procedure, updosing procedure, and oral food challenges 
is the risk of anaphylaxis.  Symptoms of anaphylaxis may include pruritus, urticaria, angioedema, wheezing, cough, 
dyspnea, emesis, diarrhea, and hypotension that may progress to hypotensive shock.      
The potential discomforts with the Initial Dose Escalation Day procedure, updosing procedure, and oral food challenges 
are no more than when eating the suspected food in the past. Symptoms are usually transient lasting less than 2 hours 
and include pruritus, urticaria, nausea, abdominal discomfort, emesis and/or diarrhea, rhinitis, and sneezing and/or 
wheezing. The major risks involved include respiratory distress and rarely anaphylactic shock. Medication, personnel, 
and equipment are immediately available in the CFRU to treat allergic reactions.  Subjects will be provided a prescription 
for an EpiPen® or EpiPen, Jr.® or equivalent to have with them at all times and to use in case of an allergic reaction. 
Risks associated with phlebotomy or insertion of an intravenous catheter include infection, syncope, and localized pain, 
stinging, bleeding, or contusions at the phlebotomy site where the needle is inserted into the vein. 
The risk involved with skin testing includes discomfort from the needle prick, along with pruritus and swelling at the skin 
test site in positive responses. Less common side effects include severe allergic reactions. 
There may be an increased risk of developing Eosinophilic esophagitis (EoE), which is an immune-mediated disease as a 
result of inflammation of the esophagus. Symptoms range by age, with children potentially presenting with feeding 
difficulties, abdominal pain, and/or vomiting and adults may experience chest pain, food getting “stuck”, and/or 
abdominal pain. If these symptoms are present, an endoscopy will be needed to confirm diagnosis, which may be 
performed by a gastroenterologist.   
The risks involved with the GI Sub-study endoscopy are rare and include bleeding, perforation of the esophagus, 
stomach or duodenum, sepsis and pneumonia.  The risks associated with the biopsy procedure include bleeding and 
perforation of the esophagus, stomach and duodenum.  The risks associated with the use of the FDA approved 
medications routinely used for standard of care endoscopies (fentanyl, midazolam and Benadryl) include respiratory 
depression, constipation, dry mouth, dizziness, blurred vision, sleepiness and agitation. 
5.5. Potential Benefits 
There are no benefits to participating in this study.  A potential benefit for the subjects randomized to the active 
(peanut) oral immunotherapy is the potential decrease in the subject’s reactivity to peanuts after an accidental 
exposure/ ingestion of peanut.  The likelihood of this is unknown. 
6. Investigational Agent

disposition of the investigational agent, including the date and quantity of the drug received, to whom the drug was 
dispensed (participant-by-participant accounting), and a detailed accounting of any drug accidentally or deliberately 
destroyed. 
Original records for receipt, storage, use, and disposition will be maintained by the study site.  An original drug-
dispensing log will be kept current for each participant.  This log will contain the identification of each participant and 
the date and quantity of drug dispensed. 
All records regarding the disposition of the investigational product will be available for inspection. 
Following study drug/placebo administration, the site personnel will retain all empty or partially used vials.  All drug 
material will be released and recorded by the nutrition personnel. 
6.3. Assessment of Participant Compliance with Investigational Agent 
Families will document daily dosing and any reaction from at-home dosing on diary logs.  Monitoring of compliance will 
be performed by reviewing the participant’s diary and monitoring and counting their returned study medication. Unused 
study medication will be brought back to the CFRU with each visit and collected by study staff for reconciliation of 
remaining peanut/oat flour. 
6.4. Toxicity Prevention and Management 
Reactions to Peanut OIT During Initial Dose Escalation Day 
Participants may develop symptoms during the initial escalation. The investigator’s judgment will be required to 
determine the best course of action with possible actions being: 
1. Extend time interval between dosing (up to an additional 30 minutes). 
2. Return to previously tolerated dose (i.e., repeat of last tolerated dose) then advance forward. 
3. Discontinue protocol. 
For oral or pharyngeal pruritus, the action should be to continue the normal dosing in 30 minutes. 
For mild symptoms, defined as: 
• 
skin — limited or localized hives or swelling, skin flushing or pruritus 
• 
respiratory — rhinorrhea or sneezing, nasal congestion, occasional cough, throat discomfort 
• 
GI — mild abdominal discomfort or minor episode of vomiting 
 
the action should be either to repeat the last dose in 30-60 minutes or to advance in 30-60 minutes depending on the 
physician’s discretion. 
For moderate symptoms, defined as: 
• 
skin — systemic hives or swelling 
• 
respiratory — throat tightness without hoarseness, persistent cough, wheezing without 
• 
dyspnea 
• 
GI — persistent moderate abdominal pain/cramping/nausea, increased vomiting 
the action should be to implement a 30-60 minute observation period and if symptoms resolve, reduce the dose by one 
step, repeat the same dose, or increase the dose by one step; if symptoms continue or worsen, the participant can be 
treated with antihistamines: if symptoms resolve, reduce the dose by one step, repeat the same dose, or increase the 
dose by one step; if symptoms require additional treatment, then consultation with the Principal Investigator is 
warranted to determine the next course of action. 
For severe symptoms, defined as: 
• 
respiratory — laryngeal edema, throat tightness with hoarseness, wheezing with dyspnea 


28 
 
• 
GI — significant severe abdominal pain/cramping/repetitive vomiting 
• 
neurological — change in mental status 
• 
circulatory — hypotension 
The initial escalation dose should be discontinued and the appropriate rescue medications administered. 
If the subject requires treatment for symptoms with antihistamines on one occasion during the initial escalation 
protocol, then the rest of the protocol may be followed. If the subject requires more than one medication (e.g., 
albuterol, diphenhydramine, epinephrine, or others) or multiple doses of antihistamines, the initial escalation protocol 
should be terminated. 
The PI will be available for questions and decision making for any questions related to the study protocol at all times. 
All subjects will be observed for a minimum of 2 hours following administration of the final dose and will be discharged 
only when deemed clinically stable by a study physician. 
Figure 3: Management of Symptoms During Initial Dose Escalation Day 
 
 
 
Reactions to Peanut OIT During Build-up or Maintenance Phase 
To be able to be eligible for an updosing or maintenance dose visit, subjects cannot have active wheezing, spirometry (as 
per manual of procedures) demonstrating FEV1 <80% predicted, or a current flare of atopic dermatitis that 
contraindicates updosing in the clinical judgment of the study physician.  As needed, subjects will be maintained on their 
current dose of study product until their flare of asthma or atopic dermatitis is resolved.   


29 
 
If a subject has an updosing in the CFRU without symptoms, the action should be to continue per protocol with daily 
home dosing of the tolerated dose with the next updosing visit 2 weeks later.   
If the subject only experiences oral/pharyngeal pruritus during the administration of the daily dose, then the same dose 
can be repeated the next day at home and continued throughout the interval unless other symptoms begin to develop. 
For other mild symptoms (Objective, APPENDIX 4), the action should be either to repeat the dose the next day (day 2) at 
home or to have the subject return to the CFRU the next day (day 2) for a repeat of the previous day’s dose or the last 
tolerated dose (at the study physician’s discretion).  If the dose is tolerated, then the subject will continue on that dose 
and return at the normal interval.  If the dose causes mild symptoms again, then the subject may return to the CFRU the 
next day (day 3) and be given the last tolerated dose or a 1-2 step dose reduction.  If tolerated, the subject will continue 
on this dose for the normal time interval.  If mild symptoms recur, a 1-2 step reduction should be administered the next 
day (day 4).  If tolerated then that dose should be continued for 2 weeks.  If not tolerated, consultation with the PI is 
indicated.   
If moderate symptoms (Grade 2, APPENDIX 4) occur, the action should be to have the subject return to the CFRU the 
next day (day 2) for dosing with the previous days dose or the last tolerated dose, at study physician discretion, under 
observation.  If the dose is tolerated, the subject will continue on that daily home dose for the normal time interval per 
protocol.  If the subject does not tolerate this dose, the subject should receive the last tolerated dose or a 1-2 step dose 
reduction the next day (day 3) in the CFRU or at home if the planned dose was previously tolerated.  If this dose is 
tolerated, it will be continued as the daily home dose for the normal time interval, then escalation attempted in the 
CFRU as noted below.  If this dose is not tolerated, then the next dose will be a 1-2-step reduction in dosing, and the 
dose will be given on the CFRU the next day (day 4).  If this next dose is not tolerated, then a discussion with the PI will 
ensue to make a decision about whether to continue the subject on active treatment in the study. 
If severe symptoms (Grade 3, APPENDIX 4) occur the action should be to treat the subject, and at the study physician’s 
discretion either 1) have them return to the CFRU the next day (day 2) for dosing with a 2-step reduction in dose under 
observation or 2) discontinue them from the active treatment.  If the subject tolerates the dose reduction, then they will 
remain on that dose for 2 weeks and then return to the CFRU for the dose escalation.  A discussion with the PI may 
ensue to make a decision about whether to continue the subject on active treatment in the study. 
If a subject fails dose escalation after three consecutive (with 2-4 weeks between) attempts, he/she will be considered a 
dose escalation failure and the last tolerated dose will be accepted as the maintenance dose.  
For a completed dose escalation with no symptoms, subjects should be observed for 30 minutes.  For mild symptoms, 
subjects should have a 1-2 hours post-protocol observation period.  For moderate to severe symptoms, the observation 
period should be at least 4 hours and up to 24 hours based on symptoms and treatment regimen needed to stabilize the 
subject. 
Any subject deemed to have severe allergic reactions to OIT, including hypoxia, hypotension or change in mental status 
and receives aggressive therapy (e.g., IV fluid resuscitation, mechanical ventilation, repeated doses of epinephrine for a 
life threatening reaction) at any time should be discussed with the PI and discontinued from active therapy. 
For specific questions related to dosing escalation or continuation of the same dose that are not answered in the above 
protocol, the PI will be available for questions and decision-making.   
Any subject who discontinues build-up dosing due to repeated allergic reactions to the characterized peanut allergen 
will have his/her blood drawn for mechanistic studies within approximately 1 week of discontinuation of therapy. 
 
6.5. Premature Discontinuation of Investigational Agent 
Study therapy may be prematurely discontinued for any participant for any of the following reasons: 
• 
Anaphylaxis resulting in hypotension, neurological compromise or mechanical ventilation secondary to peanut 
OIT dosing or any peanut food challenge 


30 
 
Any subject deemed to have severe allergic reactions to OIT and who receives aggressive therapy (e.g., IV fluid 
resuscitation, mechanical ventilation, repeated doses of epinephrine for a life threatening reaction) at any time should 
be discontinued from further therapy.  The circumstances include, but may not be limited to, the following: 
• 
Poor control or persistent activation of secondary atopic disease (e.g., AD, asthma)  
• 
Started on beta-blockers, or other prohibited medications, with no alternative medications available per the 
prescribing physician 
• 
Pregnancy  
• 
Circumstances (e.g., concurrent illness, such as gastroenteritis) requiring missed peanut OIT maintenance dosing 
of > 7 consecutive days  
• 
Non-adherence with home peanut OIT dosing protocol (excessive missed days; i.e., > 3 consecutive days missed 
on 3 or more occasions) without consulting with study staff would be a safety issue warranting discontinuation 
Any  subject may be prematurely terminated from the study if: 
• 
The subject elects to avoid consent from all future study activities, including follow-up 
• 
The subject is “lost to follow-up” (i.e., no further follow-up is possible because attempts to reestablish contact 
with the subject have failed)  
• 
The subject develops biopsy-documented eosinophilic esophagitis (EoE) with clinical symptoms or other 
eosinophilic gastrointestinal disease 
• 
The subject dies  
• 
Study therapy may also be prematurely discontinued for any participant if the investigator believes that the 
study treatment is no longer in the best interest of the participant 
Follow-up of Subjects Who Discontinue Treatment Only 
Subjects who prematurely discontinue treatment with peanut OIT may remain in the study until the end of study visit at 
Week 156.  All willing subjects will be followed every 13 weeks for the duration of the study to monitor safety and 
efficacy parameters.  
Subjects who initiate therapy (i.e., who do not fail the Initial Dose Escalation Day AND also initiate home dosing) in this 
trial will not be replaced. 
7. Other Medications 
7.1. Concomitant Medications 
7.1.1. Protocol-mandated 
There are no protocol-mandated concomitant medications. 
7.1.2.  Other permitted concomitant medications 
All subjects may continue their usual medications, including those taken for asthma, allergic rhinitis and atopic 
dermatitis, during the study.  However, they must be able to discontinue antihistamines prior to the initial day of 
escalation, skin testing and all oral food challenges.  Usual topical steroid use is permitted at the time of skin 
testing.  Systemic (oral, IV, IM) steroid use longer than 5 days at one time or longer than 3 weeks (21 days) 
duration each year is not allowed.  Up-dosing will not occur within 3 days of systemic steroid use. 
7.2. Prophylactic Medications 
There will be no prophylactic medications required in this protocol. 
7.3. Prohibited Medications 


31 
 
• 
Omalizumab (Xolair) 
• 
Systemic (oral, IV, IM) corticosteroids used for any greater than 5 days at one time or longer than a total of 
3 weeks (21 days) duration each year for asthma.  If used, subjects must not be up-dosed until at least 3 days 
after ceasing the administration of oral steroids 
• 
Oral β-blockers 
7.4. Rescue Medications  
Treatment of individual allergic reactions during peanut OIT therapy should be with either an antihistamine and/or 
epinephrine, along with IV fluids, albuterol and steroids as indicated.  Subjects and parents are likely to already have 
EpiPens®, but for those who do not, a prescription for EpiPens® (or equivalent device) will be provided.  Subjects and 
parents will be trained in proper use and will be able to demonstrate proper technique with the EpiPen® (or equivalent 
device). 
Generally, for mild and moderate symptoms, the subject should receive antihistamines, and for more severe symptoms, 
the subjects should receive epinephrine, antihistamines, and then the other medications as indicated. If severe 
anaphylaxis occurs at any time, dose escalation will stop and the dose will be reduced to the last tolerated dose and the 
subject continued on that dose as long-term maintenance without further escalation. 
Antihistamines 
If a subject requires only antihistamines for treatment of allergic symptoms, the dose escalation can be continued.  If 
symptoms during a build-up day require antihistamines in multiple doses or in combination with other medications 
(except epinephrine), there should be a dose reduction by 1-2 doses with the next dose given in CFRU.  If dose 
escalation fails or requires treatment after two more escalation attempts each spaced 2 to 4 weeks apart, the dose 
should be reduced to the last tolerated dose and continued long term without further escalation.   
Epinephrine 
Any reaction (in CFRU or at home) that requires two or more doses of epinephrine will halt further dose escalation for 
this individual. Maintenance on the last tolerated dose would be continued. 
CFRU 
If a single administration of epinephrine is required during in CFRU escalation, the dose should be reduced by two doses, 
and the subject continued on that dose for four weeks.  After 4 weeks at the reduced dose, an escalation attempt may 
be tried in CFRU. 
If a single administration of epinephrine is required a second consecutive time during this escalation attempt, the dose 
should be reduced by two doses, and the subject continues on that dose for 6-8 weeks.  After 6-8 weeks at the reduced 
dose, an escalation attempt may be tried in CFRU. 
If a single administration of epinephrine is required a third consecutive time during this escalation attempt, the dose 
should be reduced by two doses and the subject continued on that dose as long-term maintenance without further 
escalation. 
Home 
If a single administration of epinephrine use occurs during dosing at home, this epinephrine use is not counted as one of 
the uses described above, unless severe anaphylaxis occurs at home. The subject should return to CFRU for an observed 
dose prior to resuming any dosing at home. 
8. Study Procedures 
8.1. Enrollment 


32 
 
The research study will be explained in lay terms to each potential research participant. The potential participant will 
sign an informed consent form before undergoing any study procedures.  Participants will be considered enrolled into 
the study and assigned a unique study identification number after signing the informed consent/assent document(s).  
8.2. Screening/Baseline Visit(s) 
The purpose of the screening period is to confirm eligibility to continue in the study. The Screening/Baseline 
assessments may take place over several visits.  All assessments must be completed no more than 10 months (Appendix 
1) preceding initiation of peanut/placebo treatment.  Baseline/screening visits following requirements below, conducted 
under a different protocol within the past 10 months prior to IDED, can be used towards this study. 
The following procedures, assessments, and laboratory measures will be conducted to determine participant eligibility: 
• 
Consent and assent  
• 
Medical history, including review of all food allergies 
• 
Physical assessment 
• 
Blood draw for peanut-specific IgE and IgG4 measurement 
• 
Skin prick test to peanut extract (neat extract with no dilution, Greer Laboratories, Lenoir, NC) 
• 
Spirometry 
• 
DBPCFC to a 500 mg cumulative total peanut protein 
• 
Pregnancy test, if subject is a female who has undergone menarche and is of childbearing potential (i.e., not 
otherwise incapable of having children from a previous medical condition, surgery, or other circumstance) 
Any of the above items may be repeated within the 10 months preceding initiation of study treatment if warranted, in 
the opinion of the investigator, by changes in the subject’s clinical status. 
Double-Blind Placebo-Controlled Food Challenge (DBPCFC) at Screening 
Randomization and preparation of the challenge materials will be performed by trained study personnel in the GMP 
facility at Stanford. Prior to the food challenge, subjects will be asked to restrict the use of oral antihistamines (five 
half-lives), beta-agonists (12 hours), theophylline (12 hours), and cromolyn (12 hours).  
The screening DBPCFC will consist of 7 doses of peanut given every 15-30 minutes in increasing amounts up to a 
cumulative total of 500 mg of peanut protein. If the study team suspects a reaction may be developing, they may 
exercise their clinical judgment to separate doses by up to an additional 30 minutes (one hour maximum between 
doses).  The other challenge will consist of placebo material given also in 7 doses. The doses will be 5 mg, 20 mg, 50 mg, 
100 mg, 100 mg, 100 mg, and 125 mg. Before each challenge, the subject will have a physical assessment administered 
by a trained physician’s assistant, registered nurse, nurse practitioner, and/or physician of the study team who is blinded 
to the testing material. The supervising investigator will also be blinded to testing material.   
Reactions will be scored using a Food Challenge Symptom Score sheet (see criteria in Appendix 4). If the subject begins 
to have any objective symptoms or subjective symptoms deemed clinically significant, the food challenge will be 
terminated and the subject will be given appropriate treatment. The subject will be observed for a minimum of two 
hours after the final administered dose and discharged only when deemed clinically stable by a study physician.  All food 
challenges will be performed under physician supervision. If the subject has no symptoms related to allergic reactions to 
the peanut ingestion with the DBPCFC, they will not be enrolled in the study. 
Separate GI Substudy. 
After enrollment into the study, participants who are 18 y.o. or over will be asked, via a separate consent,  if they are 
interested in participating in a study in which biopsies are obtained of the gastrointestinal track to test for safety and 
efficacy markers. There will be an upper GI endoscopy scheduled at baseline and then again at week 52, 104, and week 
117 (or equivalent) of the protocol. We expect to enroll approximately 20 adult subjects in this subset. 
Subjects will undergo an endoscopy prior to their IDED. This will be performed by a board certified gastroenterologist at 
Stanford Endoscopy suite. This will be performed under mild anesthesia using fentanyl, versed and midazolam and 


33 
 
subjects will be observed in the endoscopy recovery room per standard of care. Biopsies will be taken from the 
esophagus, stomach and duodenum. 
8.3. Study Visits  
 
Peanut OIT Treatment Overview 
Peanut OIT administration will include an Initial Dose Escalation Day (IDED) with peanut oral immunotherapy dosing 
beginning at 0.5 mg with graduated doses up to 6 mg (if tolerated) occurring in the Stanford CFRU. Subjects tolerating 
less than 1.5 mg single dose will be considered an Initial Dose Escalation Day failure and will be discontinued from the 
study.  
A targeted history and physical assessment will be performed at each in person visit. Physical assessments performed in 
this protocol will be allergy focused and include the following systems: head and neck, including thyroid; eyes, ears, 
nose, and throat; lungs; heart; abdomen; and skin. Subjects will be assessed for exacerbation of atopic dermatitis or 
asthma (as determined by active wheezing) prior to each in-CFRU dosing.  In the presence of an exacerbation of atopic 
dermatitis, the study physician will use their professional judgment in deciding whether the exacerbation should 
preclude an attempt at updosing.  In the presence of wheezing in any child, regardless of asthma history, spirometry 
(per manual of procedures) will be performed to assess FEV1.  If FEV1<80% predicted value, bronchodilators will be 
administered and spirometry will be repeated.  If FEV1 ≥80% predicted value (with or without bronchodilator 
administration) the updose will be attempted in CFRU.  If FEV1 <80% predicted value after bronchodilator 
administration, the participant will remain at their current dose for two additional weeks.  That day’s dose may be 
administered either in CFRU and monitored as an updose. 
In addition to dosing visits, subjects will return to the CFRU at designated visits (see Appendix 1) for their OFC or other 
assessments/blood draws. A medical and diary review, and targeted physical assessment will also be performed at these 
visits. OFCs will occur every 3 months (approximately every 13 weeks) beginning with week 104.  
After subjects have met the criteria outlined above (Section 3.1), medical history, diet history, spirometry, SPT, and a 
physical assessment will be performed.  These subjects will be randomized 1:1 either to avoid OIT therapy (see Figure 1), 
and begin the avoidance phase, or they will be randomized to decrease their daily dose to 300 mg of peanut protein.  
After 3 months both arms will be re-challenged with 4,000 mg peanut protein, and then every 13 weeks for up to 4 
additional OFCs.  The placebo group may be unblinded to the research staff at week 117. 
 
Peanut OIT: 
Initial Dose Escalation Day (Day 0) – The Initial Dose Escalation (IDE) Day will be done at the CFRU  and consist of peanut 
OIT dosing, beginning at 0.5 mg of peanut protein with graduated doses every 30 minutes up to 6 mg (see schedule for 
initial day dose escalation, Table 1).  Subjects will not have active wheezing, spirometry demonstrating FEV1 <80% 
predicted, or a current flare of atopic dermatitis that contraindicates dosing in the clinical judgment of the study 
physician.  A physician will be present at all times during any of the CFRU peanut OIT dosing visits and will be available to 
respond within 60 seconds to any allergic reaction.  Subjects tolerating the 6 mg single dose will remain on that daily 
dose for 2 weeks.  They will then return every 2 weeks to the CFRU for single updose.  Subjects who do not tolerate the 
1.5 mg dose will be considered treatment failures and will not initiate home dosing.

Up-dosing phase (build-up phase) (Week 1-44):  Subjects will receive subsequent doses (Table 2) at home for the next 14 
days. Subjects who tolerate only 1.5 mg on the IDED will return in 7 days for updosing to 3 mg and then return 7 days 
later for updosing to 6 mg before proceeding to dose #6. Subjects who tolerate only 3 mg on the IDED will return in 7 
days for updosing to 6 mg before proceeding to dose #6.  Subjects will be instructed to continue dietary peanut 
avoidance throughout the entire study. They will also be instructed not to introduce any new foods to the diet and to 
continue avoidance of the subject’s other known food allergens, if any. At 2-week intervals, the subjects will return for a 
possible increase in the daily oral dose until they reach 4,000 mg peanut protein build-up phase).   
During dose escalation, there should be increased hydration (i.e. about 16 oz or more given orally) and restricted 
exercise for 2 hours after dosing.

Subjects will begin the CFRU dosing schedule as outlined above until 4,000 mg of peanut protein is reached.  Any 
updosing attempts may be postponed for 1-2 extra visits based on clinical judgment.  However, an updosing attempt 
must be made within a maximum of 3 consecutive scheduled clinic visits.  Subjects should withhold their daily home 
dose and any prophylactic antihistamines on the in-CFRU updosing day but should take all other prescribed medications.  
Note that the daily home dose should be taken as part of a meal at a consistent time (within 24±2 hours of the previous 
day’s dose), and it is critical to take the dose every day.  Doses should be separated by at least 12 hours.  Subjects who 
require dosing reduction during the 2-week period due to illness will undergo an attempted updosing only after 
resuming their full dose for a minimum 3 days.  
As stated above, an updosing attempt must be made within 3 clinic visits on a given dose, unless updosing is delayed 
due to administration of epinephrine as defined in Section 7.4 or illness.  If the subject fails to successfully increase 
updosing for three consecutive attempts, updosing will be halted at the last tolerated dose and the subject will continue 
on that dose as their maintenance dose for the remainder of the study.  The subject will be followed for the remainder 
of the study for safety and immunologic monitoring.   
Vigorous exercise is not permitted for at least 2 hours after the dose of oral allergen immunotherapy. Also, there must 
be at least 1 hour between vigorous exercise and taking a dose of oral allergen immunotherapy. Allergic reactions are 
still possible when exercise takes place more than 2 hours after the dose. 
Should significant systemic symptoms, which may include mild symptoms based on physician discretion or moderate or 
greater symptoms, be reported during the daily home dosing, the symptom/dosing algorithm will be followed to 
determine the best course of action.  The appropriate treatment will depend on the type and number of symptoms.  
Subjects will be allowed to take their other daily medications during the build-up and maintenance phases of the study 
(i.e., antihistamines, albuterol) except where prohibited in this protocol.  
Every 13 weeks during the build-up phase, subjects will have blood drawn for mechanistic labs, including basophil 
activation studies and pregnancy testing, if applicable.  Blood will be collected prior to attempted dose escalations, but 
the decision to updose will be made based on clinical parameters, not the results of the assays. 
Weeks 52, 65, 78, and 91– Maintenance Phase 
Subjects will undergo updosing until reaching a daily maintenance dose of 4,000 mg and they will remain at that dose 
and return for follow-up visits at Weeks 52, 65, 78, and 91.  Each of these visits will include a physical assessment, 
spirometry, skin test, and blood draw for mechanistic studies.  Based on our previous data using a similar dosing method 
(Table 2), we expect all subjects on active treatment to reach 4,000 mg between the Week 44 and Week 78 visits. 
 
Week 104 – On Study DBPCFC (to 4,000 mg) 
At Week 104 all subjects will have a DBPCFC to 4,000 mg (as per staged challenge above) to assess desensitization. The 
visit will also include a physical assessment, spirometry, skin prick test and blood draw for mechanistic studies.  
The subject’s sensitivity to peanut allergen is defined as the dose at which the subject experiences allergic reactions. All 
symptoms and signs will be evaluated and rated based on a standardized oral food challenge scoring system 
(Appendix 4).  
During the oral food challenge, there should be increased hydration (i.e. about 16 oz or more orally). 
 
Updosing during the DBPCFC will be stopped when the Principal Investigator (or designee) finds symptoms and/or signs 
that indicate a definite allergic reaction (Bock scoring system (objective, Appendix 4) has occurred based on clinically 
significant changes in reported symptoms, physical findings, or vital signs that the subject is experiencing to the 
challenge material.  The challenge will consist of 7 doses (peanut or placebo), given about every 15-30 minutes for lower 
doses and about every 45 minutes or longer for higher doses (in bold): 5 mg, 50 mg, 220 mg, 625 mg, 1,000 mg, and 
1,050 mg and 1,050 mg (4,000 mg protein total).  The doses for DBPCFCs conducted on or after Week 104 in this 


36 
 
protocol were selected with the rationale that some study subjects will be receiving placebo and would be expected to 
maintain the same level of sensitivity displayed at the screening DBPCFC to a cumulative dose of 500 mg of peanut 
protein.  Both peanut and oat protein will be concealed in a food that masks the taste.  After the last dose of the 
DBPCFC, the subject will be monitored for 2 hours and then discharged home.  Subjects will be considered to have 
tolerated the OFC if they do not experience any objective reactions by Bock’s Criteria (Appendix 4). 
If the subject experiences reactions, they will be treated with the necessary rescue medications.  They will be observed 
for a minimum two hours after the final administered dose and discharged home only when deemed clinically stable by 
a study physician. 
After the Week 104 DBPCFC, subjects who meet the following criteria will reduce their daily maintenance dose to 300 
mg  peanut protein daily or to discontinue peanut protein daily dosing entirely (i.e., switch to 600mg oat flour): 
• 
On OIT treatment for minimum 104 weeks,  
• 
Taking daily maintenance dose of 4,000 mg protein for at least 3 months, 
• 
No severe reactions (Bock’s Criteria Grade 3, APPENDIX 4) to home dosing from Week 92-Week 104, and/or 
• 
No objective reactions by Bock’s Criteria, Appendix 4 at the DBPCFC at Week 104 
Subjects who do not meet these criteria at Week 104 will be considered desensitization failures and will be offered a 
follow-up protocol that is separate from this protocol once they reach the primary endpoint.  They will be considered in 
statistical analyses of the intent-to-treat population. 
After Week 104, double blinding will continue by using the same quantity of  flour for all groups (600 mg total of oat 
flour daily for placebo group and 600 mg total of oat flour daily for avoidance group; approximately 600 mg total of 
peanut flour --to provide exactly 300 mg peanut protein—for the 300 mg peanut protein  group). 
Separate GI Sub Study. 
Subjects will undergo the second endoscopy at week 52, and a third endoscopy at week 104 and a fourth endoscopy at 
week 117 (or equivalent). These will be performed by a board certified gastroenterologist at Stanford Endoscopy suite. 
This will be performed under mild anesthesia using fentanyl, versed and midazolam and subjects will be observed in the 
endoscopy recovery room per standard of care. Biopsies will be taken from the esophagus, stomach and duodenum. 
 
Weeks 117 (or equivalent), 130, 143, and 156 – On Study DBPCFC (to 4,000 mg) 
At Weeks 117 (or equivalent), 130, 143, and 156, subjects will have a DBPCFC to 4,000 mg (as per staged challenge 
above) to assess tolerance.  Subjects who fail these challenges (i.e., who exhibit objective reactions by Bock’s Criteria, 
Appendix 4) will be offered a follow-up protocol that is separate from this protocol. 
Subjects who are randomized either to 300 mg peanut protein or peanut avoidance or the placebo subjects who pass 
the week 104 criteria will return to CFRU at Weeks 117 (or equivalent), 130, 143, and 156.  Each of these visits will 
include a physical assessment, spirometry, skin test, blood draw for mechanistic studies, and a DBPCFC to 4,000 mg as 
outlined above to assess clinical reactivity.   
During the oral food challenge, there should be increased hydration (i.e. about 16 oz or more given orally). 
There are no data indicating that repeating food challenges every 3 months will or will not induce desensitization or 
otherwise affect the outcomes in this study. Our preliminary studies in which we have performed DBPCFCs every 3 
months in a separate phase 1 study cohort (n=87 subjects) have demonstrated no increased risk of sensitization. 
8.4. 1. Unscheduled Visits  


37 
 
If disease activity increases or other concerns arise between regularly scheduled visits, participants should be instructed 
to contact study personnel and may be asked to return to the study site for an “unscheduled” visit.  
Unscheduled visits may be performed for significant food allergy episodes which may be reported by the subject 
between regularly scheduled visits.  Significant food allergy episodes are defined as those for which epinephrine is 
administered based on criteria in the subject’s Food Allergy Action Plan.  Unscheduled visits may include physical 
assessment, blood draw and/or skin prick test.  Review of the circumstances around the episode and appropriate 
documentation of the adverse event will be recorded in the study chart.

Logistics: Blood samples will be collected every 12-13 weeks during the subject’s participation in the study.  Volumes 
collected will follow NIH guidelines (for children: 5 ml/kg at any single draw, no more than 9.5 ml/kg over an 8-week 
period; adults: the smaller of 10.5 ml/kg or 550 ml total at any single draw). 
IV) GI biopsy assays: 
We will perform three major procedures on the GI biopsies: 
a. 
immunohistochemistry to identify cells-inflammatory and regulatory (mast cells, basophils, eosinophils, T cells, 
B cells, dendritic cells, and epithelial cells and associated markers –for example  TSLP, IL-33, IL-18, IL-10,  CD103, 
IL-4, IL-13, histamine, STAT6, GATA3, T-bet, IFN-g, TGF-b) 
b. 
single cell sorting with RNA Seq 
c. 
cryopreservation for future analysis outside the scope of the proposal 
 
10. Biospecimen Storage 
Biospecimen storage will occur in the Nadeau laboratory using a previously validated and published storage procedure 
for samples (available upon request).  
 
11. Criteria for Participant and Study Completion and Premature Study Termination 


42 
 
11.1. Participant Completion 
Completion of the study will be defined as reaching the Week 117 (or equivalent) visit and participating in at least 90% 
of CFRU visits. 
11.2. Participant Stopping Rules and Withdrawal Criteria 
Participants may be prematurely terminated from the study for the following reasons: 
1. The participant elects to withdraw consent from all future study activities, including follow-up. 
2. The participant is “lost to follow-up” (i.e., no further follow-up is possible because attempts to reestablish 
contact with the participant have failed). 
3. The participant dies.  
4. The Investigator no longer believes participation is in the best interest of the participant. 
5. Individual safety stopping rules  
a. Missing >7 consecutive days of OIT therapy (e.g., concurrent illness such as gastroenteritis) 
b. Missing >3 consecutive days of OIT therapy on 3 occasions without consulting with study staff   
c. Anaphylaxis resulting in hypotension, neurological compromise or mechanical ventilation secondary to 
OIT dosing or any peanut food challenge 
d. Any allergic reaction to study drug requiring more than 2 doses of epinephrine due to single event 
e. The subject develops biopsy-documented eosinophilic esophagitis (EoE) with symptoms or other 
eosinophilic gastrointestinal disease 
f. Any subject deemed to have severe allergic reactions and who receives aggressive therapy (e.g., IV fluid 
resuscitation, mechanical ventilation, repeated doses of epinephrine for a life threatening reaction) at 
any time should be discontinued from further therapy.   
g. Other circumstances including, but not limited to, the following: 
i. Poor control or persistent activation of secondary atopic disease (e.g., AD, asthma)  
ii. Started on beta-blockers, or other prohibited medications, with no alternative medications 
available per the prescribing physician 
iii. Pregnancy  
11.3. Participant Replacement 
Subjects who initiate therapy (i.e., who do not fail the Initial Dose Escalation Day AND also initiate home dosing) in this 
trial will not be replaced. 
11.4. Follow-up after Early Study Withdrawal 
Subjects who prematurely discontinue treatment with OIT may remain in the study until end of study visit at week 156.  
All willing subjects will be followed every 13 weeks for the duration of the study to monitor safety and efficacy 
parameters.  These visits will include skin testing and a blood draw for mechanistic studies. 
If the subject refuses this follow-up, or begins and then elects to discontinue the follow-up, they will be asked to come in 
for a final study visit consisting of a physical assessment, skin test, blood draw, review of their Food Allergy Action Plan, 
and instructions to discontinue any OIT dosing. 
11.5.  Study Stopping Rules 
During the course of the study, if the investigator or the NIAID Medical Officer discovers conditions that indicate that the 
study should be discontinued, an appropriate procedure for stopping the study pending DSMB review will be instituted, 
including notification of the FDA and IRB. 


43 
 
If any of the stopping rules listed below are met, study enrollment will be suspended, the Initial Dose Escalation days will 
be suspended, dose escalation during Build-up will be stopped, and all enrolled participants will remain on their current 
dose pending expedited review of all pertinent data: 
• 
Any death related to peanut OIT dosing 
• 
One case of severe and prolonged anaphylaxis that does not respond to 3 doses of epinephrine, 
or that includes intubation and that is related to peanut dosing or to oral food challenge. 
• 
More than 2 cases of hypotension related to peanut dosing or to oral food challenge. 
• 
More than 3 participants require more than 2 injections of epinephrine for anaphylaxis during a single dosing 
event of the peanut product. 
• 
More than 3 of either of the following events: 
o Severe adverse event, other than anaphylaxis, related to investigational product or 
o Eosinophilic esophagitis with clinical symptoms and confirmatory biopsy findings 
12. Safety Monitoring and Reporting 
12.1.  Overview 
This section defines the types of safety data that will be collected under this protocol and outlines the procedures for 
appropriately collecting, grading, recording, and reporting those data.  
12.2.  Definitions 
12.2.1.  Adverse Event (AE) 
Any untoward or unfavorable medical occurrence associated with the subject’s participation in the research, whether or 
not considered related to the subject’s participation in the research (modified from the definition of adverse events in 
the 1996 International Conference on Harmonization E-6 Guidelines for Good Clinical Practice) (from OHRP "Guidance 
on Reviewing and Reporting Unanticipated Problems Involving Risks to Subjects or Others and Adverse Events 
(1/15/07)" http://www.hhs.gov/ohrp/policy/advevntguid.html#Q2 )  
For this study, an adverse event will include any untoward or unfavorable medical occurrence associated with:   
• 
Study therapy regimen:  
Home OIT Dosing 
• 
Food allergy episodes in response to home dosing that are objective Grade 1 or 2 by Modified Bock’s 
Criteria (APPENDIX 4) will be recorded on the paper AE CRFs and graded by CTCAE v 4.03 criteria. 
• 
Food allergy episodes in response to home dosing that are Grade 3 by Modified Bock’s Criteria 
(APPENDIX 4) or that are classified as SAEs defined in Section 12.2.3 below will be recorded on the 
AE/SAE CRF as appropriate and graded by CTCAE v 4.03 criteria. 
• 
Study mandated procedures:  
For the procedures below, clinical situations are listed that are considered to be outside the normal 
range of outcomes and will be recorded as Adverse Events.  These situations do not limit an investigator 
from recording and reporting any other events, associated or not with these procedures as AEs.    
Allergen Skin Testing 
• 
Prolonged (>24 hours) itching at test site 
• 
Swelling (> 10 cm ) at site of test lasting more than 24 hours 
• 
Nasal allergic symptoms within 30 minutes from the procedure 
• 
Fainting /Vasovagal event within 30 minutes from the procedure 
 


44 
 
Phlebotomy 
• 
Bruising at phlebotomy site >5 cm with onset within 24 hours of procedure 
• 
Erythema at phlebotomy site >5 cm with onset within 24 hours of procedure 
• 
Infection at phlebotomy site 
• 
Fainting /Vasovagal event within 30 minutes from the procedure 
 
Double-Blind Placebo Controlled Food Challenges 
• 
During DBPCFCs, reactions will be recorded.  DBPCFC material is not considered study drug, and as such, 
reactions will be recorded and reported separately.  GI biopsies 
• 
GI biopsies will be performed on a voluntary subset of participants via an endoscopy.  Adverse 
events will be monitored and documented per the AE listings. Any adverse events related to the 
procedure or medications used and that meet the criteria for SAE will be reported per the SAE 
matrix to the FDA and the NIAID medical monitor.  
12.2.1.1.  Suspected Adverse Reaction (SAR)  
Any adverse event for which there is a reasonable possibility that the investigational drug [or 
investigational study therapy regimen] caused the adverse event. For the purposes of safety reporting, 
‘reasonable possibility’ means there is evidence to suggest a causal relationship between the drug and 
the adverse event. A suspected adverse reaction implies a lesser degree of certainty about causality 
than adverse reaction, which means any adverse event caused by a drug (21 CFR 312.32(a)). 
12.2.2.  Unexpected Adverse Event  
An adverse event or suspected adverse reaction is considered “unexpected” if it is not listed in the Investigator 
Brochure or package insert or is not listed at the specificity, severity or rate of occurrence that has been 
observed; or, if an Investigator Brochure is not required or available, is not consistent with the risk information 
described in the general investigational plan or elsewhere in the IND or protocol. 
The Principal Investigator will review all adverse events related to skin prick testing, spirometry, DBPCFC, or 
other study procedures to determine if they are unexpected.  
12.2.3.  Serious Adverse Event (SAE) 
An adverse event or suspected adverse reaction is considered “serious” if it results in any of the following 
outcomes (21 CFR 312.32(a)): 
1. Death. 
2. A life-threatening event: An AE or SAR is considered “life-threatening” if its occurrence places the subject at 
immediate risk of death. It does not include an AE or SAR that, had it occurred in a more severe form, might 
have caused death.  
3. Inpatient hospitalization or prolongation of existing hospitalization. 
4. Persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions. 
5. Congenital anomaly or birth defect.  
6. Important medical events that may not result in death, be life threatening, or require hospitalization may be 
considered serious when, based upon appropriate medical judgment, they may jeopardize the subject and 
may require medical or surgical intervention to prevent one of the outcomes listed above. 
Elective hospitalizations or hospital admissions for the purpose of conduct of protocol mandated procedures are 
not to be reported as an SAE unless hospitalization is prolonged due to complications. 
12.3.  Grading and Attribution of Adverse Events 
12.3.1.  Grading Criteria 


45 
 
The study physician will grade the severity of adverse events experienced by the study subjects according to the 
criteria set forth in the National Cancer Institute’s Common Terminology Criteria for Adverse Events 
(CTCAE) v4.03. This document (referred to herein as the NCI-CTCAE manual) provides a common language to 
describe levels of severity, to analyze and interpret data, and to articulate the clinical significance of all adverse 
events. The NCI-CTCAE has been reviewed by the Principal Investigator and has been deemed appropriate for 
the subject population to be studied in this protocol.  
Adverse events will be graded on a scale from 1 to 5 according to the following standards in the NCI-CTCAE 
manual: 
Grade 1 = mild adverse event. 
Grade 2 = moderate adverse event. 
Grade 3 = severe and undesirable adverse event. 
Grade 4 = life-threatening or disabling adverse event. 
Grade 5 = death. 
Events Grade 1 or higher will be recorded on the appropriate paper AE case report form for this study. 
Anaphylaxis will be defined when there is: 1) Symptomatic bronchospasm, with or without urticaria, 
with parenteral intervention indicated with edema and hypotension; or 2) Life-threatening 
consequences with urgent intervention indicated. 
 
12.3.2.  Attribution Definitions 
The relationship, or attribution, of an adverse event to the study therapy regimen or study procedure(s) will 
initially be determined by the site investigator/study physician and recorded on the appropriate AE/SAE paper 
case report form and according to SUSAR guidelines 
(http://www.fda.gov/downloads/Drugs/.../Guidances/UCM227351.pdf)Final determination of attribution of SAE 
for safety reporting will be determined by DAIT/NIAID.   
For additional information and a printable version of the NCI-CTCAE manual, consult the NCI-CTCAE web site: 
http://ctep.cancer.gov/reporting/ctc.html. 
       
 
12.4.  Collection and Recording of Adverse Events 
12.4.1.  Collection Period 
Adverse events will be collected from the time of consent until a subject completes study participation or until 
30 days after he/she prematurely withdraws (without withdrawing consent) or is withdrawn from the study. 
12.4.2.  Collecting Adverse Events 
Adverse events (including SAEs) may be discovered through any of these methods: 
• 
Observing the subject. 
• 
Interviewing the subject [e.g., using a checklist, structured questioning, diary, etc.]  . 
• 
Receiving an unsolicited complaint from the subject. 
12.4.3.  Recording Adverse Events 
Throughout the study, the investigator will record adverse events and serious adverse events as described 
previously (Section 12.2, Definitions) on the appropriate AE/SAE paper CRF regardless of the relationship to 
study therapy regimen or study procedure. 


46 
 
Once recorded, an AE/SAE will be followed until it resolves with or without sequelae, or until 30 days after the 
subject prematurely withdraws (without withdrawing consent)/or is withdrawn from the study, whichever 
occurs first. 
12.5. Reporting of Serious Adverse Events and Adverse Events 
12.5.1.  Reporting of Serious Adverse Events to Sponsor 
This section describes the responsibilities of the site investigator to report serious adverse events to the 
sponsor. Timely reporting of adverse events is required by 21 CFR and ICH E6 guidelines.  
The site investigator will report to the NIAID Medical Monitor and the Independent Medical Monitor all serious 
adverse events within 24 hours of becoming aware of the event, regardless of relationship or expectedness.  
CONTACT INFORMATION FOR NIAID MEDICAL MONITOR:

For serious adverse events, all requested information on the AE/SAE paper CRF will be provided.  However, 
unavailable details of the event will not delay submission of the known information.  As additional details 
become available, the AE/SAE paper CRF will be updated and submitted. 
12.5.1.1.  Reporting of Unexpected Non-Serious Adverse Events 
An unexpected, non-serious adverse event that is of Grade 2 severity or higher and study related will be 
recorded and reported to the NIAID Medical Monitor and the Independent Medical Monitor.     
12.5.2.  Reporting to Health Authority 
Dr. Nadeau will be the sponsor of the IND and has the responsibility of reporting all AEs and SAEs to the FDA 
within the reporting time limits set forth by the FDA.   It is Dr. Nadeau’s ultimate responsibility to report any 
serious adverse event to the Independent Medical Monitor at her site and to the NIAID Medical Monitor within 
24 hours of becoming aware of the event.  IND sponsor must report the event to the appropriate health 
authorities using one of these two options: 
12.5.2.1.  Standard Reporting (IND Annual Report) 
 
This option applies if the AE is classified as one of the following:  
o Serious, expected, suspected adverse reactions (see Section 12.2.1.1, Suspected Adverse Reaction, 
and Section 12.2.2, Unexpected Adverse Event). 
o Serious and not a suspected adverse reaction (see Section 12.2.2, Suspected Adverse Reaction). 
o Pregnancies  
Note that all adverse events (not just those requiring 24-hour reporting) will be reported in the Annual IND 
Report. 
12.5.2.2.  Expedited Safety Reporting  
• Expedited reporting is required.  
This option applies if the AE is classified as one of the following:  


47 
 
Serious and unexpected suspected adverse reaction [SUSAR] (see Section 12.2.1.1, Suspected Adverse 
Reaction and Section 12.2, Unexpected Adverse Event and 21 CFR 312.32(c)(1)i 
o The IND sponsor, Dr. Nadeau, must report any suspected adverse reaction that is both serious and 
unexpected. The IND sponsor must report an adverse event as a suspected adverse reaction only if there 
is evidence to suggest a causal relationship between the study drug and the adverse event, such as: 
 
A single occurrence of an event that is uncommon and known to be strongly associated with 
drug exposure.  
 
One or more occurrences of an event that is not commonly associated with drug exposure, but 
is otherwise uncommon in the population exposed to the drug  
o Aggregate analysis of specific serious adverse events observed in a clinical trial (such as known 
consequences of the underlying disease or condition under investigation or other events that commonly 
occur in the study population independent of drug therapy) that indicates those events occur more 
frequently in the drug treatment group than in a concurrent or historical control group. 
o Any findings from clinical or epidemiological studies, analysis of data pooled across multiple studies, 
published or unpublished scientific papers, or from animal or in vitro testing that would result in a 
safety-related change in the protocol, informed consent, General Investigational Plan section of the IND 
or other aspects of the overall conduct of the trial. 
SUSARs must be reported to the FDA within FDA calendar days; fatal or immediately and must be 
reported to the FDA within 7 calendar days. All of these must also be reported to the NIAID medical 
monitor within 24 hours so that s/he can report to the NIAID/DAIT DSMB within the same 15 or 7 day 
timeframe. The site principal investigator must report SAEs to their respective IRBs as mandated by 
them. The site principal investigator must report SAEs to their respective IRBs as mandated by them. 
To report a SUSAR, a finalized, initial SAE case report form (Appendix 2) and a MedWatch 3500A form 
will be generated by the site Principal Investigator and must be approved by the NIAID Medical Monitor.   
  
Any findings from studies that suggests a significant human risk  
 
The IND sponsor, Dr. Nadeau,  shall report any findings from other epidemiological studies, analyses of 
adverse events within the current study or pooled analysis across clinical studies or animal or in vitro 
testing (e.g. mutagenicity, teratogenicity, carcinogenicity) that suggest a significant risk in humans 
exposed to the drug that would result in a safety-related change in the protocol, informed consent, 
investigator brochure or package insert or other aspects of the overall conduct of the study.   
 
12.5.3.  Reporting of Adverse Events to IRBs/IECs 
The site investigator shall report adverse events, including expedited reports, in a timely fashion to their 
respective IRBs/IECs in accordance with applicable regulations and guidelines. All Safety Reports to the FDA 
shall be distributed by Dr. Nadeau.  
   12.6.   
Pregnancy Reporting 
The investigator shall be informed immediately of any pregnancy in a study subject who has initiated study 
treatment. A pregnant subject shall be instructed to stop taking study medication. The investigator shall counsel 
the subject and discuss the risks of continuing with the pregnancy and the possible effects on the fetus. 
Monitoring of the pregnant subject shall continue until the conclusion of the pregnancy.    
The investigator shall report to the DAIT/NIAID all pregnancies within 1 business day of becoming aware of the 
event using the Pregnancy paper CRF.  All pregnancies identified during the study shall be followed to conclusion 
and the outcome of each must be reported.  The Pregnancy paper CRF shall be updated and submitted to the 
DAIT/NIAID when details about the outcome are available.   
Information requested about the delivery shall include: 


48 
 
o 
Gestational age at delivery 
o 
Birth weight, length, and head circumference 
o 
Gender 
o 
Appearance, pulse, grimace, activity, and respiration (APGAR) score at 1 minute, 5 minutes, and 24 hours 
after birth, if available 
o 
Any abnormalities. 
Any complication to pregnancy such as a congenital abnormality or birth defect shall be submitted as an SAE to 
the DAIT/NIAID using the SAE reporting procedures described above and to the FDA. 
12.7.  Reporting of Other Safety Information 
The site investigator shall promptly notify the site IRB as well as the DAIT/NIAID when an “unanticipated 
problem involving risks to subjects or others” is identified, which is not otherwise reportable as an adverse 
event. 
12.8.  Review of Safety Information 
12.8.1. Medical Monitor Review 
The DAIT/NIAID Medical Monitor shall receive annual reports from the protocol chair compiling new and 
accumulating information on AEs, SAEs, and pregnancies recorded by the study site(s) on appropriate paper 
CRFs. 
In addition, the Medical Monitor shall review and make decisions on the disposition of the SAE and pregnancy 
reports received by the protocol investigator (See Sections 12.5.1, Reporting of Serious Adverse Events to 
Sponsor, and 12.6, Pregnancy Reporting).   
12.8.2.  DSMB Review   
12.8.2.1.  Planned DSMB Reviews  
The NIAID Allergy and Asthma Data and Safety Monitoring Board (DSMB) shall review safety data at 
least yearly during planned DSMB Data Review Meetings. Data for the planned safety reviews will 
include, at a minimum, a listing of all reported AEs and SAEs.   
The DSMB will be informed of an Expedited Safety Report submitted to the FDA. 
12.8.2.2.  Ad hoc DSMB Reviews  
In addition to the pre-scheduled data reviews and planned safety monitoring, the DSMB may be called 
upon for ad hoc reviews. The DSMB will  review any event that potentially impacts safety at the request 
of the NIAID Medical Monitor. In addition, the following events will trigger an ad hoc comprehensive 
DSMB Safety Review:  
o 
Any death that occurs in the study. 
o 
The occurrence of the same unexpected SAE in 3 or more of the study participants who have 
received a study treatment. 
After review of the data, the DSMB will make recommendations regarding study conduct and/or 
continuation. 
12.8.2.2.1.  Temporary Suspension of Enrollment and/or Drug Dosing for ad hoc DSMB Safety 
Review  
A temporary halt in enrollment and/or drug updosing will be implemented if an ad hoc DSMB 
safety review is required per the criteria outlined in section 12.8.2.2. above. 
In the event of a study halt for DSMB review, subjects in the screening phase will continue to 
undergo screening procedures unless the review was triggered by events related to screening.   


49 
 
Subjects already receiving therapy will remain on study treatment at their current tolerated 
dose. 
Based on the outcome of the DSMB review, the consent and/or assent forms may be revised.  
Upon approval of these revisions by the IRB, all subjects who have previously provided informed 
consent for the study and are affected by the new information will be re-consented. 
13. Statistical Considerations and Analytical Plan 
13.1 Overview  
This double blind, randomized, placebo controlled study in peanut-allergic children and adults intends to identify 
basic immune mechanisms that explain the effects of OIT in individuals who do or do not become clinically 
tolerant and to determine whether immune monitoring can predict safety and outcomes in OIT protocols. 
The 120 enrolled subjects will be randomized 2.4:1.4:1. Thus, there will be three arms: (1) Arm A (60 subjects) 
on peanut OIT until week 104 and once meeting criteria [i.e.  1) assigned to OIT treatment for minimum 104 weeks, 2) 
reaching maintenance 13 weeks prior to DBPCFC at week 104 3) no severe reactions (Grade 3, APPENDIX 4) to home dosing 
from Week 92-Week 104, and/or 4) no objective reactions, (Appendix 4) at the Week 104 DBPCFC]   has been assigned to 
avoid peanut (i.e. 600 mg oat flour). (2) Arm B (35 subjects) on peanut OIT until week 104 and once meeting 
criteria, has been assigned to be maintained on 300 mg peanut protein (i.e. 600 mg peanut flour). (3) Arm C (25 
subjects) that is maintained on placebo (oat flour) and once meeting criteria, will receive 600 mg oat flour 
beginning on week 104. This will be true even if a subject in the placebo group meets criteria at week 104. This 
way all participants will receive approximately the same volume of flour so that the subject blinding will be 
easier to maintain. The decision to maintain subjects on only 300 mg peanut protein after week 104 is for ease 
of eating peanut for so long.  This upfront randomization is performed because our statistical analysis plan is 
focused on intent-to-treat principles.     
The primary analysis is an intent-to-treat comparison of success rates between arms A and C, where success is 
defined by reaching and passing the DBPCFC at both 104 weeks and 117 (or equivalent) weeks. 
 
 
 
13.2. Endpoints 
 
Primary Endpoint 
• 
Proportion of peanut allergic subjects who pass a DBPCFC after the 3 month avoidance period 
(Week 117 or equivalent) following the end of active treatment phase.  
 
Measurement: A DBPCFC is considered a “pass” if the subject has no clinical reactivity during the challenge 
(from administration of first dose through observation period lasting 2 hours after administration of the final 
dose). 
Secondary Endpoints: 
• 
Proportion of PA subjects who pass a DBPCFC after a 6 month avoidance period. 
• 
Proportion of PA subjects who pass a DBPCFC after a 9 month avoidance period. 
• 
Proportion of PA subjects who pass a DBPCFC after a 12 month avoidance period. 
• 
Proportion of PA subjects who can successfully complete the build-up phase of peanut OIT to the 
highest dose (4,000 mg of peanut protein) with only mild (Objective, APPENDIX 4) symptoms  


50 
 
• 
Proportion of PA subjects who can successfully undergo the build-up and maintenance phases of 
peanut OIT with only mild symptoms. 
• 
Comparison of the proportion of subjects in placebo, avoidance, and 300 mg peanut protein groups 
who are able to undergo DBPCFCs with no clinical reactivity after initiating OIT. 
 
Measurement of Secondary Endpoints:  For measurement of Bullets 1-3 and Bullet 6, see Measurement of 
Primary Endpoint above.  Data for measurement of Bullets 4 and 5 will be collected from subject diaries, 
reviewed at every updosing visit attempt and DBPCFC visit conducted after successful completion of the Initial 
Dose Escalation Day. 
13.3. 
Measures to Minimize Bias 
This study will employ a randomized, double-blind, placebo controlled design (peanut OIT vs. placebo OIT).  
13.4. Analysis Plan 
13.4.1 Analysis Populations 
• 
Intent-to-treat (ITT) sample: All subjects who are randomized will comprise the ITT sample. 
 
• 
Safety sample: All enrolled subjects who receive at least one dose of OIT or placebo.  Participants in the 
safety sample will be analyzed according to the treatment they actually received, regardless of their 
randomized assignment. 
13.4.2 
Primary Analysis of Primary Endpoint(s)/Outcome(s)   
The primary analysis is an ITT comparison of success rates between arms A and C (defined in Section 
13.1), where success is defined by reaching and passing the DBPCFC at Week 117 (or equivalent).  An 
unevaluable test will be considered a failure.  The analysis will be performed using the binomial test of 
proportions.  A two-sided alpha level of 0.05 will be used.  The success rate in each of the three arms will 
also be estimated, with 95% exact binomial confidence interval. 
13.4.3 
Supportive Analyses of the Primary Endpoint(s)/Outcome(s)  
If any relevant covariates are imbalanced between arms A and C, the primary comparison will also be 
performed using a multivariable logistic regression model controlling for those variables. 
The primary comparison will be repeated between arms A and B, using the binomial test of proportions 
with two-sided alpha level of 0.05. 
13.4.4 
Analyses of Secondary and Other Endpoint(s)/Outcome(s) 
The following proportions will be estimated, with 95% exact binomial confidence intervals: 
• 
Proportion in arm A who pass the DBPCFC week 130, 143, and 156 of peanut avoidance,  
• 
Proportion, in arms A and B combined, who can successfully complete the build-up phase of 
peanut OIT to the highest dose (4,000 mg of peanut protein) with only mild (Objective, 
APPENDIX 4) symptoms, 
• 
Proportion, in arms A and B combined, who can successfully undergo the build-up and 
maintenance phases of peanut OIT with only mild symptoms, 
• 
Proportion, in arms A and B combined, defined as treatment failures at initial dose escalation or 
at 1000 mg protein,   
• 
Proportions, in arms A and B separately, who are defined as desensitization failures at week 117 
(or equivalent), 130, 143, and 156, and 


51 
 
• 
Proportion, in arm A who are defined as tolerance failures at week 117 (or equivalent), 130, 143, 
and 156. 
Adverse events will be tabulated, using the safety sample. 
13.4.5 
Analyses of Exploratory Endpoint(s)/Outcome(s) 
We will use blood samples and clinical outcome measurements from this study to identify specific 
features of the immune response that are associated with ”clinical tolerance” at week 104, 117 (or 
equivalent), 130, 143, and 156.  We will also determine special immune features associated with 
subjects who are desensitized at week 104, 117 (or equivalent), 130, 143, and 156. It will be important 
to compare any of the immune features to those of the placebo arm, treatment failures, tolerance 
failures, and desensitization failures.  This exploratory objective may be examined prior to study 
closeout.  In such a case, only the statisticians will have access to identity of study arm.  Study arm, 
however, will not be a variable in the analysis prior to study closeout.  Instead the outcome of interest 
will be clinical tolerance/desensitization across study arms and the interest will lie in correlating 
molecular features to the outcome. 
A number of post-hoc analyses for predicting clinical outcomes will be completed looking at clinical and 
mechanistic variables. 
13.4.6 
Descriptive Analyses  
Descriptive statistics (proportions for categorical variables, means and standard deviations for 
continuous variables) will be reported for all key participant variables, including baseline and 
demographic characteristics, use of medications, compliance, and study completion status. 
13.5.1 Interim Analyses  
N/A – There will be no interim analyses in this protocol. 
Although no formal interim analyses are specified, we will examine one set of exploratory 
objectives prior to study closeout that do not involve our primary efficacy endpoint, nor do they 
reveal data by study arm.  Specifically, the outcome of interest will be clinical 
tolerance/desensitization aggregated across study arms and the interest will lie in correlating molecular 
features to the outcome. 
 
13.6. Statistical Hypotheses  
For the primary comparison, the following will be tested: 
• 
Null hypothesis: The success rate (where success is passing the DBPCFC at both 104 and 117 (or 
equivalent) weeks) is equal in arms A (active treatment followed by 3 months of avoidance) and C 
(placebo). 
• 
Alternative hypothesis: The success rate differs between arms A and C. 
As a secondary comparison, the following will be tested: 
• 
Null hypothesis: The success rate is equal in arms A and B (active treatment followed by 3 months of 
300mg peanut protein treatment). 
• 
Alternative hypothesis: The success rate differs between arms A and B. 
13.7. Sample Size Considerations  
In the previous trial by Burks et al, 2013 the rate of success among subjects treated as in arm A was 0.35.  
Literature (Sampson, et al. 2013) suggests that the rate of success among subjects on placebo (as in arm C) is 


52 
 
0.05 or less.  Using a binomial test of proportions with two-sided alpha level 0.05, the sample size of 60 
subjects on arm A and 25 subjects on arm C yields 90% power to detect that difference (between rates of 0.35 
and 0.05).  According to the definition of the endpoint – passing the DBPCFC at both 104 and 117 (or 
equivalent) weeks – subjects who drop out of the study are included in the analysis (counted as failures).  
Therefore, the analysis will include all subjects randomized to arm A or arm C, and the sample size is not 
decreased due to drop-outs. 
The following table displays the power for other possible success rates in the two arms.

14. Identification and Access to Source Data 
14.1. Source Data 
Source documents and source data are considered to be the original documentation where subject information, visits 
consultations, assessments and other information are recorded.   Documentation of source data is necessary for the 
reconstruction, evaluation and validation of clinical findings, observations and other activities during a clinical trial.  
In this protocol, source data will be recorded onto paper CRFs at the time of collection.  Skin test results will be recorded 
via adhesive tape transfer of the outline of any wheal(s) and/or erythema.  Spirometry results will be recorded as 
printouts from the software package used to perform the testing.  
14.2. Access to Source Data 
The site investigator and site staff will make all source data available to the PPD Monitor, DAIT/NIAID, as well as to the 
FDA.  Authorized representatives as noted above are bound to maintain the strict confidentiality of medical and 
research information that may be linked to identify individuals. 
15. Protocol Deviations 
15.1. Protocol Deviation Definitions 
Protocol Deviation – The investigators and site staff will conduct the study in accordance to the protocol; no deviations 
from the protocol are permitted.  Any change, divergence, or departure from the study design or procedures constitutes 
a protocol deviation.  As a result of any deviation, corrective actions will be developed by the site, approved by the 
NIAID and then implemented promptly. 
 
Major Protocol Deviation - A major protocol deviation is a deviation from the IRB approved protocol that may affect the 
subject's rights, safety, or well-being and/or the completeness, accuracy and reliability of the study data.  In addition, 
major protocol deviations include willful or knowing breaches of human subject protection regulations, or policies, any 
action that is inconsistent with the NIH Human Research Protection Program’s research, medical, and ethical principles, 
and a serious or continuing noncompliance with federal, state, local or institutional human subject protection 


53 
 
regulations, policies, or procedures.  This also includes departures from GCPs and pharmacy handling of the 
investigational product and accountability. 
 
Non-Major Protocol Deviation - A non-major protocol deviation is any change, divergence, or departure from the study design or 
procedures of a research protocol that does not have a major impact on the subject's rights, safety or well-being, or the 
completeness, accuracy and reliability of the study data. 
15.2. Reporting and Managing Protocol Deviations 
The study site principal investigator has the responsibility to identify, document and report protocol deviations as 
directed by the NIAID (Appendix 3).  However, protocol deviations may also be identified during site monitoring visits 
conducted by the PPD monitor, or during other forms of study conduct review.  
Deviations from the protocol will be reviewed by the NIAID project manager, on a case-by-case basis, to determine if the 
deviation meets major or non-major criteria.  All protocol deviations and the reasons for such deviations must be noted 
on the appropriate CRF. 
Protocol Deviation reports will be submitted by study site personnel in accordance with requirements from the local IRB, 
the FDA, and the NIAID.  Action plans to prevent deviations going forward will be reviewed and approved by the NIAID 
Project Manager and Medical Monitor. 
16. Ethical Considerations and Compliance with Good clinical Practice 
16.1. Statement of Compliance 
This clinical study will be conducted using good clinical practice (GCP), as delineated in Guidance for Industry: E6 Good 
Clinical Practice Consolidated Guidance, and according to the criteria specified in this study protocol.  Before study 
initiation, the protocol and the informed consent documents will be reviewed and approved by the IRB.  Any 
amendments to the protocol or to the consent materials will also be approved by the IRB before they are implemented. 
16.2. Informed Consent Process 
The consent process will provide information about the study to a prospective participant and will allow adequate time 
for review and discussion prior to his/her decision.  The principal investigator or study physician listed on the FDA 1572 
will review the consent and answer questions with the potential participant and the study physician must sign the 
consent form with the participant and document the informed consent process.  For minors participating in this study, 
informed consent will be obtained from their parent(s) or legal guardian(s).  Minors participating in this study will 
provide assent if they are capable.  The prospective participant will be told that being in the trial is voluntary and that he 
or she may withdraw from the study at any time, for any reason.  All participants (or their legally acceptable 
representative) will read, sign, and date a consent form before undergoing any study procedures.  Consent materials will 
be presented in participants’ primary language. A copy of the signed consent form will be given to the participant. 
The consent process will be ongoing.  The consent form will be revised when important new safety information is 
available, the protocol is amended, and/or new information becomes available that may affect participation in the 
study.  
16.3. Privacy and Confidentiality 
A participant’s privacy and confidentiality will be respected throughout the study.  Each participant will be assigned a 
unique identification number and these numbers rather than names will be used to collect, store, and report participant 
information.  Site personnel will not transmit documents containing personal health identifiers (PHI) to the study 
sponsor or their representatives. 
17. Publication Policy 


54 
 
Every possible effort will be made for the primary outcome of the trial to be published in a peer-reviewed journal within 
12 months after the database is locked.  The DAIT/NIAID will review and comment on any manuscript derived from this 
trial prior to submission and the NIH data sharing policy 
(http://grants.nih.gov/grants/policy/data_sharing/data_sharing_guidance.htm#goals).  Data from this trial will be 
shared in accordance to the specific plan that was included in the grant application.]
