Brief summary:
This is a phase II open label study on the use of Ibrutinib on the inhibition of food-induced anaphylaxis in adults with food allergy. Ibrutinib (brand name Imbruvica) is currently FDA approved for the treatment of mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), and Waldenstrom's macroglobulineia (WM). We propose to administer this approved drug to adults with food allergy to inhibit food allergy responses.

Detailed description:
This is open-label study designed to determine the fewest doses and shortest length of time, from two days to up to 7 days, needed for ibrutinib to fully inhibit tests for food allergy, and to determine the length of persistence of efficacy after the drug is stopped.

Arms: arm 1: Allergic subjects will be given ibrutinib 420mg daily for 2-7 doses to determine the shortest amount of time and fewest ibrutinib doses required to suppress food skin prick testing and basophil activation test reactivity.
Interventions: intervention 1: Ibrutinib
Intervention descriptions: intervention 1: Ibrutinib 420mg, PO once daily for 2-7 days

This is a phase II open label study on the use of Ibrutinib on the inhibition of food-induced anaphylaxis in 
adults with food allergy.  Ibrutinib (brand name Imbruvica) is currently FDA approved for the treatment of 
mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), and Waldenstrom’s macroglobulineia 
(WM).  We propose to administer this approved drug to adults with food allergy to inhibit anaphylaxis.  
STUDY SCHEMA 
This is open-label study consists of 2 parts.  Part 1 is designed to determine the fewest doses and 
shortest length of time, from two days to up to 7 days, needed for ibrutinib to fully inhibit tests for food 
allergy, and to determine the length of persistence of efficacy after the drug is stopped.  Part 2 is 
designed to determine the ability of ibrutinib, optimally dosed as defined in Part 1, to prevent signs and 
symptoms of anaphylaxis during a food challenge in food-
allergic subjects.    
   
Part 1: At Visit 1, after undergoing informed consent 
subjects will be screened for eligibility (history, skin prick test 
[SPT] to peanut/tree nuts with histamine and saline SPT 
positive and negative controls, respectively, basophil 
activation test [BAT], peanut or tree nut-specific IgE).  30 mL 
of peripheral blood will be collected by a trained phlebotomist 
using standard procedures for BAT, sIgE to peanut/tree nuts 
and components, quantitative immunoglobulins (QUIGs), 
eosinophil and basophil enumeration, as well as screening 
for toxicities (see below).  After this visit, subjects will be given ibrutinib (two 
doses of 420 mg of ibrutinib to start the following day and to be taken orally at 
8am exactly 24 hours apart) and return for Visit 2 to undergo repeat PST and 
phlebotomy for testing preformed in an identical manner to Visit 1. If two 
consecutive doses of 420 mg of ibrutinib given 24 hours apart is insufficient 
to cause >80% inhibition of the SPT and BAT response, subjects will be 
given two additional doses of 420 mg of ibrutinib to continue to take at 8am 
exactly 24 hours apart for two more days, and return for Visit 3 for identical 
repeat testing as in Visits 1 and 2.  If four consecutive doses of 420 mg of 
ibrutinib given 24 hours apart is insufficient to cause >80% inhibition of the 
SPT and BAT response, subjects will be given three additional doses of 420 
mg of ibrutinib to continue to take 24 hours apart for three more 
days, and return for Visit 4 for identical repeat testing as in 
Visits 1, 2 and 3, where based on preliminary data, we expect 
SPT and BAT to be suppressed.  Once both the SPT and BAT 
responses are inhibited, no further ibrutinib doses will be given, 
and subjects will return on a weekly basis until both the peanut/tree nut PST and BAT return to at least 
80% of baseline values.  At this point, Part 1 will have been completed.  At each visit, patients will be 
monitored for toxicities, including CBC, CMP, and pregnancy testing.  Prior to drug initiation and at the 
end of the trial, an EKG will be performed.  
 
Part 2: Visit 1 will be identical to those for Part 1 except that subjects will take a higher dose of ibrutinib 
(560mg daily) for 2 days and a single-blind, placebo-controlled (SBPC) graded food challenge of up to 8 
mg of peanut or tree nut protein, administered over escalating doses, will be performed in a monitored at 
the study site in a clinical research unit (CRU) setting.  Prior to the SBPC food challenge, 30 mL of 
peripheral blood will be collected for BAT, sIgE to peanut and components, as well as for total IgE, 
eosinophil and basophil enumeration.  During the challenge, subjects will be repeatedly assessed for 
signs and symptoms of food-induced anaphylaxis between each dose per food challenge protocol.  This 
visit will establish each subject’s baseline threshold dose for peanut/tree nut reactivity.   
 
Once a confirmed reaction occurs, the food challenge will be terminated and the reaction treated until it 
has resolved. Within 15 minutes of a positive challenge, an additional 10 mL of blood will be drawn for 
mast cell microparticle analysis.  After a minimum of a two week recovery period, each subject will then 
begin taking ibrutinib 560 mg orally daily for 2 days, which is the minimum number of doses that

demonstrate efficacy as determined in Part 1.  Two hours after the final dose, subjects will return to the 
study site for Visit 2, and PST and SBPC food challenges will be repeated to establish each subject’s 
new threshold dose for peanut/tree nut reactivity while on ibrutinib, and with repeat post-challenge blood 
collection for mast cell microparticle analysis.  At this point of the protocol, ibrutinib dosing will be 
stopped.  Follow up visits starting 3 months after cessation of ibrutinib will be conducted to repeat toxicity 
labs and skin testing.

1.0 
BACKGROUND AND RATIONALE 
1.1 
Disease Background 
Food allergy is a potentially life threatening disease, and its prevalence continues to increase 
despite public health efforts (1,2)  Newer studies have shown that it is less likely that a subject will 
lose their food allergies over time and food allergies can also start in adulthood, so more adults 
now have life-threatening food allergies.  Near fatal and fatal reactions can occur of subjects with 
food allergies and can lead to devastating results (3,4).  Furthermore, the economic burden of 
childhood food allergy is nearly $25 billion per year, including 200,000 emergency department 
trips annually (5).  Despite this significant disease burden, there are currently no approved 
therapies for food allergy.  Standard of care is constant vigilance in avoidance of allergen, and 
use of self-injected epinephrine after a reaction has occurred.  Therefore, there is a large unmet 
need for new therapeutics to prevent serious allergic disease including food allergy and 
anaphylaxis.  Newly FDA approved BTK inhibitors such as ibrutinib (as well as others under 
development (6,7)) may be able to fill this void, and offer a therapy to these subjects.   
1.2 
Study Drug Background and Associated Known Toxicities 
Ibrutinib is a once daily, oral, selective, irreversible small-molecule inhibitor of Bruton’s tyrosine 
kinase (BTK), a key component of B-cell receptor signaling (8,9).  BTK is also essential for FcεRI 
signaling and triggering of mast cells and basophils (10){Iyer, 2011 #10272;Kuehn, 2008 
#10273;MacGlashan, 2011 #8797}.  It is currently FDA approved for the treatment of Mantle Cell 
Lymphoma (MCL), Chronic Lymphocytic Leukemia (CLL) and Waldenstrom’s macroglobulinemia 
(WM). 
 
In subjects with recurrent B-cell lymphoma, >90% irreversible occupancy of the BTK active site in 
peripheral blood mononuclear cells was observed up to 24 hours after ibrutinib doses of >/= 2.5 
mg/kg/day.  Ibrutinib is absorbed with a median Tmax of 1-2 hours.  It is metabolized by 
cytochrome P450 and CYP3A, and has a half-life of 4-6 hours.  The majority (80%) is fecally 
excreted.  
 
The approved CLL and WM dose (420 mg orally once daily) has been shown to inhibit allergy test 
responses in cancer subjects receiving this drug by 1 week of treatment (the earliest time point 
examined) in preliminary data from our group.  The 560 mg dose (used for MCL) has similar side-
effect and toxicity profiles as the lower dose.  Initial data from Part 1 suggests that the 420mg 
dose can at least partially (in some cases fully) inhibit skin test responses to peanut and tree nuts 
in allergic subjects after just 2 doses, with minimal side effects and no observed toxicity thus far in 
subjects taking ibrutinib for up to 7 days.  Therefore, we can justify using the higher dose of 560 
mg orally once daily for Part 2 to investigate whether this higher dose can further reduce skin test 
responses beyond what is seen with the lower dose.   
 
In human studies, ibrutinib is metabolized in the liver, and not significantly renally cleared.  In 
healthy volunteers, co-administration with CYP3A inhibitors increased Cmax, and therefore the 
drug will not be concomitantly administered with strong or moderate inhibitors of CYP3A.  Known 
toxicities in cancer subjects receiving ibrutinib chronically include bleeding events (5% of MCL 
subjects), infection (25% of MCL subjects), myelosuppression (41% of subjects), and renal 
toxicity has also been reported.  Ibrutinib is also pregnancy category D.  This underscores our 
goal of finding the fewest possible doses to achieve the anti-allergy effect we are seeking, which 
could be as few as just 2 doses. 
1.3 
Rationale 
There are currently no treatments for food allergy. IgE uniquely arms mast cells and basophils via 
their surface expression of FcεRI in allergy.  Crosslinking of the receptor is known to activate a 
number of SRC-family kinases (e.g., LYN, SYK) required for receptor function. BTK is a key 


PROTOCOL                                                                                                                                                      Version: Aug 7, 2017

component of FcεRI signaling and triggering of mast cells and basophils.  Since signaling 
mediated by FcεRI aggregation is thought to require the activity of BTK (8,9), MacGlashan et. al. 
(9) tested ibrutinib, formerly known as PCI-32765, for its ability to prevent activation of human 
basophils in vitro. For stimulation with anti-IgE, ibrutinib inhibited CD63, CD203c and CD11b 
upregulation, and release of histamine, LTC4 and IL-4 as well as the cytosolic calcium response 
(IC90 of ≈50 nM).  Ibrutinib did not inhibit basophil activation by FMLP or C5a and did not inhibit 
IL-13 release induced by IL-3, suggesting that BTK is required for IgE-mediated activation of 
human basophils.  We propose to test whether this pharmacology can be exploited in vivo to 
prevent allergic reactions. 
 
Peanut and tree nut allergies are among the most common adult food allergens, and can 
often be the most severe.  Additionally, peanut and tree nut allergies are often life-long.  Young 
adults and adolescents have a higher rate of accidental exposure and mortality as a result of food 
allergies than younger children, so there is an unmet need for therapies directed at food allergy, 
especially in this population.  Therefore, we have chosen peanut and tree nut allergies in an effort 
to investigate a treatment that has the potential to benefit the most individuals with a potentially 
severe allergy.

3.1.6 
Women of child bearing potential must agree to two forms of highly effective 
contraception (hormonal, device, or barrier method of birth control; abstinence) 
prior to study entry, for the duration of study participation, and for 90 days 
following completion of therapy.  Should a woman become pregnant or suspect 
she is pregnant while participating in this study, she should inform the Principal 
Investigator and her treating physician immediately. 
 
3.1.5.1 A female of child bearing potential is any woman (regardless of sexual 
orientation, having undergone a tubal ligation, or remaining celibate by 
choice) who meets the following criteria: 
 
Has not undergone a hysterectomy or bilateral oophorectomy; or 
 
Has not been naturally postmenopausal for at least 12 consecutive 
months (i.e., has had menses at any time in the preceding 12 
consecutive months). 
 
3.1.7 
Ability to understand and the willingness to sign a written informed consent. 
 
3.1.8 
Ability to clearly understand and speak English at an 8th grade reading level. For 
safety reasons, subjects must speak English due to the anticipated need for clear 
and timely communication with investigators and the study team in emergency 
situations, since the investigators and study team are English speaking. 
3.2 
Exclusion Criteria 
 
3.2.1 
Subjects who have been on immunomodulatory therapies or oral corticosteroids 
within 1 month prior to study participation will be excluded, and those taking 
antihistamines must stop these drugs for one week prior to enrollment and must 
refrain from taking antihistamines during the duration of the study so as not to 
interfere with SPT responses. 
 
3.2.2 
Subjects with symptoms not consistent with type 1 food reactions (atopic 
dermatitis, eosinophilic esophagitis and any other non-IgE-mediated food 
sensitivities) will be excluded.

3.2.3 
History of allergic reactions attributed to compounds of similar chemical or 
biologic composition to ibrutinib. 
 
3.2.4 
Uncontrolled inter-current illness including, but not limited to, ongoing or active 
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac 
arrhythmia, beta-blocker use or psychiatric illness/social situations that would 
limit compliance with study requirements. 
 
3.2.5 
Subjects must not be pregnant or nursing due to the potential for congenital 
abnormalities and the potential of this regimen to harm nursing infants. 
 
3.2.6 
Subjects on anticoagulants, anti-platelet therapy, or any other predisposition 
towards bleeding. 
 
3.2.7 
Subjects with history of idiopathic urticaria, dermatographism, idiopathic or 
unexplained anaphylaxis, or anaphylaxis (to foods or otherwise) resulting in 
intubation, prolonged hypotension, or neurological sequelae 
3.3 
Study Stopping Criteria 
The study will be stopped if >50% of patients cannot complete the protocol due to 
toxicities or adverse events.  Toxicities (section 4.2) and adverse events (section 7.0) are 
listed below. Monitoring is described in section 8.0.  
3.4 
Recruitment 
Patients with a diagnosis of peanut or tree nut allergy by a board certified allergist-
immunologist will be identified as potential subjects from the allergy clinics at 
Northwestern University Feinberg School of Medicine. The treating physician will ask 
potential subjects permission to be contacted by study personnel. Potential subjects will 
then be contacted by authorized study personnel and given time to review the study 
information and consider participation.  
 
4.0 
TREATMENT PLAN 
4.1 
Treatment Dosage and Administration 
 
For Part 1 of the study, we will determine the length of treatment (i.e., the number of daily 
doses) required to inhibit both basophil and food skin test responses.  Preliminary data 
demonstrates that 7 days of treatment will inhibit both basophil and mast cell 
responsiveness to aeroallergens, but have not yet tested shorter time points.  Prior 
studies in cancer subjects suggest that one dose is sufficient to completely inhibit BAT, 
but we propose a minimum of two doses to allow for diffusion and penetration of ibrutinib 
into the skin compartment where our SPT is performed to assess skin mast cell 
responsiveness.  For Part 1, 6 subjects will take ibrutinib 420 mg, by mouth once daily 
(every 24 hours) on an outpatient basis.  After two days, the subject will undergo blood 
testing and SPT to assess basophil and mast cell reactivity.  If both tests are negative, 
Part 1 is completed.  If both tests are not negative, then the subject will take 2 more days 
of ibrutinib (same dose, for a total of 4 doses), and identical testing will be repeated. If 
testing is not negative at day 4, the subject will take 3 more days of ibrutinib (same dose, 
for a total of 7 doses), which is the maximum anticipated number of doses needed to 
suppress both the BAT and SPT.  


PROTOCOL                                                                                                                                                      Version: Aug 7, 2017 
________________________________________________________________________ 
8 
 
For Part 2 of the study, 6 subjects will take ibrutinib 560 mg once daily by mouth (every 
24 hours) for 2 days, which is the minimum number of days required to cause ≥80% 
inhibition of food SPT and BAT responses as determined in part 1.  Part 2 will last a 
minimum of 3 days. 
 
Dose-limiting toxicity (DLT) includes any grade 3 or 4 hematologic toxicity, grade 3 
hepatotoxicity or increase in creatinine x 2.5 normal limit.  DLT will be monitored at each 
visit, at any time during treatment.   
 
Maximally tolerated dose (MTD) will occur at the point DLT occurs.  Ibrutinib is approved 
as a daily medication for another indication, and we propose to use the drug in adults 
only at its approved oral dosing of 420 or 560 mg daily for a minimum of two days and a 
maximum of 7 days.  Dose limiting events include grade 3 or 4 hematologic events, grade 
3 or 4 hepatotoxicity, AST or ALT >3 times normal range, creatinine > 2.5 times normal 
range.  DLT evaluation will be completed throughout the study, anytime during treatment.  
 
In healthy volunteers, co-administration with CYP3A inhibitors increased Cmax, and 
therefore the drug will not be concomitantly administered with strong or moderate 
inhibitors of CYP3A (for example, “azole” medications and subjects will be advised 
against drinking grapefruit juice). 
4.2 
Toxicities and Dosing Delays 
Any subject who receives treatment on this protocol will be evaluable for toxicity. Each 
subject will be assessed for the development of toxicity according to the Time and Events 
table (Section 5.4).  
 
At each visit, subjects will be monitored for toxicities.  If a subject develops a grade 3 or 4 
hematologic, renal, or hepatotoxicity, the medication will be stopped.  Toxicities with 
grades are listed below.

Hepatotoxicity:  Grade 3 hepatotoxicity, or an increase in AST or ALT >3 times upper limit 
of normal will result in discontinuation in protocol therapy.  
4.3 
Concomitant Medications/Treatments 
The following concomitant medications/treatments are not allowed: immunomodulatory 
therapies, oral corticosteroids within 1 month of study participation; those taking 
antihistamines must stop these drugs for one week prior to enrollment and must refrain 
from taking antihistamines during the duration of the study so as not to interfere with SPT 
responses; and any other prior investigational interventions.   
4.4 
Duration of Therapy 
Treatment will continue for a minimum of 2 days and a maximum of 7 days per Part 1 of 
the protocol.  Other reasons the medication may be discontinued include: 
 
Inter-current illness that prevents further administration of treatment; 
 
Unacceptable adverse event(s); 
 
Subject decides to withdraw from the study; or 
 
General or specific changes in the subject’s condition render the subject 
unacceptable for further treatment in the judgment of the investigator. 
4.5 
Duration of Follow Up 
Subjects will be followed until SPT and BAT return to baseline in Part 1, and for up to 6 
months after cessation of ibrutinib treatment in Part 2. Subjects removed from treatment 
for unacceptable adverse events will be followed until resolution or stabilization of the 
adverse event.  
 
Subjects will be removed from therapy when any of the criteria listed in Section 5.5 apply. 
The Principal Investigator will be notified.  The reason for study removal and the date the 
subject was removed will be documented in the Case Report Form. The subject will be 
followed-up per protocol.

 Physical exam, vital signs 
 Urine Pregnancy test (if required) 
 CBC 
 CMP 
 Immunoglobulin levels  
 EKG 
 Spirometry (only if the subject has a history of asthma)  
 
Procedures (to be done only if labs and EKG are within normal limits) 
 Skin prick testing 
 Basophil activation test 
 SBPC oral food challenge as follows: 
 
All oral food challenges (OFC) shall be performed as single (patient)-blinded, placebo 
controlled food challenges according to standard published guidelines (11, 12).  
Placebo challenge and active challenge will be performed in that order on the same day 
if the subject has no symptoms during the first (placebo) challenge.  If a reaction 
requiring treatment occurs during the first challenge, the next challenge should not be 
performed until the symptoms have subsided. Oral food challenge to peanut or tree nut 
protein will be performed according to standard operating procedure.  At physician 
discretion, based upon history and possible subjective or very mild objective symptoms 
during a challenge, dosing intervals may be extended. 
 
Actions to minimize risk of severe allergic reactions during oral food challenge (OFC): 
Prior to the OFC visit, subjects will be told to contact study staff about asthma and 
seasonal allergy symptoms, fever, acute infections including upper respiratory 
infections, rashes or change in status of chronic medical conditions.  OFCs will be 
rescheduled in the event that any of these occur. Study staff will contact subjects 1-3 
days before the OFC to inquire about recent symptoms. 
 
All OFCs will be conducted in the Clinical Research Unit within the main hospital.  
Intravenous access will be obtained before the OFC begins.  Emergency medications 
(epinephrine, diphenhydramine, cetirizine, albuterol, ranitidine) will be immediately 
accessible in the subject’s room.  All OFCs will be conducted by trained personnel and 
supervised by a clinician with experience in performing OFCs and trained in the 
treatment of anaphylaxis.  Spirometry (assessment of pulmonary function) will be 
performed prior to the onset of the OFC. Vital signs and pulse oximetry will be obtained 
at baseline and prior to each dose of the food allergen and q15 minutes thereafter with 
an observation period of at last 2 hours after the last dose is consumed (longer should a 
reaction occur).  The OFC will begin with a low dose, which will increase incrementally.  
At physician discretion, based upon history and possible subjective or very mild 
objective symptoms during a challenge, dosing intervals may be extended.  The 
procedure will be stopped when clear objective symptoms are noted.  
 
Subjects will be discharged after a period of observation appropriate to the nature of the 
symptoms.  They will receive information regarding possible delayed manifestations 
and home treatment.  All subjects will be provided with an epinephrine auto-injector to 
take home (if they do not have one already) and instructions on how and when to use it.

Removal of Subjects from Study  
Subjects can be taken off the study treatment and/or study at any time at their own 
request, or they may be withdrawn at the discretion of the investigator for safety, 
behavioral or administrative reasons. The reason(s) for discontinuation will be 
documented and may include: 
5.5.1 
Subject voluntarily withdraws from treatment (follow-up permitted);  
5.5.2 
Subject withdraws consent (termination of treatment and follow-up); 
5.5.3 
Subject is unable to comply with protocol requirements; 
5.5.4 
Subject experiences toxicity that makes continuation in the protocol unsafe; 
5.5.5 
Treating physician judges continuation on the study would not be in the subject’s 
best interest; 
5.5.6 
Subject becomes pregnant (pregnancy to be reported along same timelines as a 
serious adverse event); or 
5.5.7 
Lost to follow-up. If a research subject cannot be located after a period of 2 
months, the subject may be considered “lost to follow-up.” All attempts to contact 
the subject during the 2 months must be documented.

7.1.2 Special Warnings and Precautions for Use 
Prior studies of ibrutinib adverse events were performed on cancer patients who had 
often failed other treatments, and were treated chronically.  However, Advani et. al. (13) 
reported side effects in a phase 1 study for only 28 days, the shortest duration of 
treatment that has been reported in the literature.  In that study, a total of 56 patients with 
a variety of relapsed B-cell malignancies were treated over seven dosage cohorts (1.25 - 
12 mg/kg/day).  For the cohort receiving dosages closest to the one being used in our 
study (a total of 6 subjects given 5 mg/kg/day, or 420 mg/day for an 81 kg person) the 
most common adverse events were typically grade 1 or 2 in severity.  Grade 3 or 4 
events were infrequent and independent of dose.  Data from this cohort of 6 subjects was 
extracted and reproduced from Table 3 of the Advani et. al. paper below.  For the entire 
cohort of 56 subjects, Grade 3-4 hematologic toxicities included neutropenia (12.5%), 
thrombocytopenia (7.2%) and anemia (7.1%).  According to the authors, no evidence of 
cumulative hematologic or non-hematologic toxicity was observed in patients with 
prolonged dosing, nor was any consistent relationship seen between dose level and 
adverse events.   
 
 
As the subjects enrolled in this study will be generally healthy except for food allergy, and 
on ibrutinib for a much shorter duration (maximum of 7 days, perhaps as little as 2 days), 
we expected adverse events to be milder and less frequent, if at all, compared to prior 
studies of ibrutinib in cancer trials.  However, for completeness, adverse events as 
documented with chronic use are detailed below.  
7.1.2.1 Hemorrhage 
Five percent of patients with MCL had Grade 3 or higher bleeding events 
(subdural hematoma, gastrointestinal bleeding, and hematuria). Overall, bleeding 
events including bruising of any grade occurred in 48% of patients with MCL 
treated with 560 mg daily. 
The mechanism for the bleeding events is not well understood. 
7.1.2.2 Infections 
Fatal and non-fatal infections have occurred with ibrutinib therapy. At least 25% 
of patients with MCL had infections Grade 3 or greater NCI Common 
Terminology Criteria for Adverse Events CTCAE) (14). 
7.1.2.3 Myelosuppression 
Treatment-emergent Grade 3 or 4 cytopenias were reported in 41% of patients. 
These included neutropenia (29%), thrombocytopenia (17%) and anemia (9%). 
Monitor complete blood counts monthly. 
7.1.2.4 Renal Toxicity 
Fatal and serious cases of renal failure have occurred with ibrutinib therapy. 
Treatment- emergent increases in creatinine levels up to 1.5 times the upper limit 
of normal occurred in 67% of patients and from 1.5 to 3 times the upper limit of 
normal in 9% of patients. Periodically monitor creatinine levels. Maintain 
hydration. 


PROTOCOL                                                                                                                                                      Version: Aug 7, 2017

7.1.2.5 Embryo-Fetal Toxicity 
Based on findings in animals, ibrutinib can cause fetal harm when administered 
to a pregnant woman. Ibrutinib caused malformations in rats at exposures 14 
times those reported in patients with MCL receiving the ibrutinib dose of 560 mg 
per day. Reduced fetal weights were observed at lower exposures. Advise 
women to avoid becoming pregnant while taking ibrutinib. If this drug is used 
during pregnancy or if the patient becomes pregnant while taking this drug, the 
patient should be apprised of the potential hazard to a fetus. 
7.1.3 
Interaction with other medications 
As stated, metabolism of ibrutinib is inhibited by CYP3A inhibitors.  Patients on 
these medications will be excluded.  
7.1.4 
Adverse Reactions 
As per package insert (15), adverse reactions are listed in Section 7.1.2. Of note, 
patients in the trial references took a larger dose and for much longer duration 
that we propose in this study.  
The most commonly occurring adverse reactions (approx. 20%) were 
thrombocytopenia, diarrhea, neutropenia, anemia, fatigue, musculoskeletal pain, 
peripheral edema, upper respiratory tract infection, nausea, bruising, dyspnea, 
constipation, rash, abdominal pain, vomiting and decreased appetite. 
The most common Grade 3 or 4 non-hematological adverse reactions (approx. 
5%) were pneumonia, abdominal pain, atrial fibrillation, diarrhea, fatigue, and 
skin infections. 
Adverse reactions from the MCL trial (N=111) using single agent IMBRUVICA 
560 mg daily occurring at a rate of approx. 10%. 
Ten patients (9%) discontinued treatment due to adverse reactions in the trial 
(N=111). The most frequent adverse reaction leading to treatment 
discontinuation was subdural hematoma (1.8%). Adverse reactions leading to 
dose reduction occurred in 14% of patients. 
Patients with MCL who develop lymphocytosis greater than 400,000/mcL have 
developed intracranial hemorrhage, lethargy, gait instability, and headache. 
However, some of these cases were in the setting of disease progression. 
Forty percent of patients had elevated uric acid levels on study including 13% 
with values above 10 mg/dL. Adverse reaction of hyperuricemia was reported for 
15% of patients.  
8.0 
ADVERSE EVENT MONITORING 
Adverse event data collection and reporting, which are required as part of every clinical trial, are 
done to ensure the safety of Subjects enrolled in the studies as well as those who will enroll in 
future studies using similar agents. Adverse events are reported in a routine manner at scheduled 
times during a trial. Additionally, certain adverse events must be reported in an expedited manner 
to allow for optimal monitoring of subject safety and care.  
 
All subjects experiencing an adverse event, regardless of its relationship to study drug/device, will 
be monitored until:  
 
the adverse event resolves or the symptoms or signs that constitute the adverse event 


PROTOCOL                                                                                                                                                      Version: Aug 7, 2017

 
any abnormal laboratory values have returned to baseline;  


8.1 
Definitions 
8.1.1 
Definition of Adverse Event 
An adverse event (AE) is any untoward medical occurrence in a subject receiving 
study treatment and which does not necessarily have a causal relationship with 
this treatment. An AE can therefore be any unfavorable and unintended sign 
(including an abnormal laboratory finding), symptom, or disease temporally 
associated with the use of an experimental intervention, whether or not related to 
the intervention.  
8.1.2  
Severity of Adverse Events 
The severity of an AE is graded as follows: 
 
Mild (grade 1): the event causes discomfort without disruption of normal daily 
activities. 
 
Moderate (grade 2): the event causes discomfort that affects normal daily 
activities. 
 
Severe (grade 3): the event makes the subject unable to perform normal daily 
activities or significantly affects his/her clinical status. 
 
Life-threatening (grade 4): the subject was at risk of death at the time of the 
event. 
 
Fatal (grade 5): the event caused death. 
8.1.3 
Serious Adverse Events 
A “serious” adverse event is defined in regulatory terminology as any untoward 
medical occurrence that: 
8.1.3.1       Results in death. 
If death results from (progression of) the disease, the disease should 
be reported as event (SAE) itself. 
8.1.3.2       Is life-threatening. 
(the subject was at risk of death at the time of the event; it does not 
refer to an event that hypothetically might have caused death if it were 
more severe). 


PROTOCOL                                                                                                                                                      Version: Aug 7, 2017 
________________________________________________________________________ 
19 
8.1.3.3       Requires in-subject hospitalization or prolongation of existing 
hospitalization for ≥ 24 hours. 
8.1.3.4       Results in persistent or significant disability or incapacity. 
8.1.3.5       Is a congenital anomaly/birth defect. 
8.1.3.6       Is an important medical event. 
 
Any event that does not meet the above criteria, but that in the judgment of the 
investigator jeopardizes the subject, may be considered for reporting as a serious 
adverse event. The event may require medical or surgical intervention to prevent 
one of the outcomes listed in the definition of “Serious Adverse Event“. For 
example: allergic bronchospasm requiring intensive treatment in an emergency 
room or at home; convulsions that may not result in hospitalization; development 
of drug abuse or drug dependency. 
8.2 
Steps to Determine If an Adverse Event Requires Expedited Reporting 
Step 1: Identify the type of adverse event. 
 
Step 2: Grade the adverse event. 
 
Step 3: Determine whether the adverse event is related to the protocol therapy  
Attribution categories are as follows: 
- Definite – The AE is clearly related to the study treatment. 
- Probable – The AE is likely related to the study treatment. 
- Possible – The AE may be related to the study treatment. 
- Unrelated – The AE is clearly NOT related to the study treatment. 
Note: This includes all events that occur within 30 days of the last dose of protocol 
treatment. Any event that occurs more than 30 days after the last dose of treatment and 
is attributed (possibly, probably, or definitely) to the agent(s) must also be reported 
accordingly. 
 
Step 4:  Determine the prior experience of the adverse event.  
Expected events are those that have been previously identified as resulting from 
administration of the agent. An adverse event is considered unexpected, for expedited 
reporting purposes only, when either the type of event or the severity of the event is not 
listed in: 
 
the current known adverse events listed in the Agent Information Section of this 
protocol; 
 
the drug package insert; 
 
the current Investigator’s Brochure 
8.3 
Reporting Requirements for Adverse Events 
8.3.1 
Expedited Reporting 
 
The Principal Investigator must be notified within 24 hours of learning of any 
serious adverse events, regardless of attribution, occurring during the study 
or within 30 days of the last administration of the study drug.  
 
The Northwestern University IRB must be notified within 5 business days of 
any unanticipated problems involving risk to subjects or others (UPIRSO). 
The following events meet the definition of UPIRSO: 


PROTOCOL                                                                                                                                                      Version: Aug 7, 2017

1. Any serious event (injuries, side effects, deaths or other problems), 
which in the opinion of the Principal Investigator was unanticipated, 
involved risk to subjects or others, and was possibly related to the 
research procedures. 
2. Any serious accidental or unintentional change to the IRB-approved 
protocol that alters the level of risk. 
3. Any deviation from the protocol taken without prior IRB review to 
eliminate apparent immediate hazard to a research subject. 
4. Any new information (e.g., publication, safety monitoring report, updated 
sponsor safety report), interim result or other finding that indicates an 
unexpected change to the risk/benefit ratio for the research. 
5. Any breach in confidentiality that may involve risk to the subject or 
others. 
6. Any complaint of a subject that indicates an unanticipated risk or that 
cannot be resolved by the Principal Investigator. 
7. The FDA should be notified within 7 business days of any unexpected 
fatal or life-threatening adverse event with possible relationship to study 
drug, and 15 business days of any event that is considered: 1) serious, 
2) unexpected, and 3) at least possibly related to study participation. 
8.3.2     Routine Reporting 
All other adverse events- such as those that are expected, or are unlikely or 
definitely not related to the study participation- are to be reported annually as part 
of regular data submission. 
8.3.3 
Stopping Rules  
The study will be stopped if >50% of patients cannot complete the protocol due to 
toxicities or adverse events.    
 
9.0 
DRUG INFORMATION 
9.1 
Ibrutinib 140 mg tablets 
 
Other names for the drug(s)/device: Imbruvica® 
 
Classification - type of agent/device: small molecule BTK inhibitor 
 
Mode of action: Ibrutinib forms a covalent bond with a cysteine residue in the BTK active 
site, leading to inhibition of BTK enzymatic activity.  BTK is a signaling molecule of the B-
cell antigen receptor (BCR) and cytokine receptor pathways. BTK’s role in signaling 
through the B-cell surface receptors results in activation of pathways necessary for B-cell 
trafficking, chemotaxis, and adhesion. Nonclinical studies show that ibrutinib inhibits 
malignant B-cell proliferation and survival in vivo as well as cell migration and substrate 
adhesion in vitro.  
 
Storage and stability:  Ibrutinib is stored at room temperature and the tablets are 
stable.  
 
Protocol dose: 420 or 560 mg once daily for 2-7 days 
 
Preparation: as supplied from the manufacturer 
 
Route of administration for this study: By mouth 
 
Incompatibilities:  N/A 


PROTOCOL                                                                                                                                                      Version: Aug 7, 2017

 
Availability: commercially available by prescription.  Medication will be paid for 
through NIH funding, and provided free of charge to subjects.  
 
Side effects: Most common side effects are diarrhea, nausea, fatigue and 
musculoskeletal pain.  Other side effects include myelosuppression, bleeding and 
hepatoxicity.  Please refer to package insert for comprehensive list of side effects.  
 
Nursing implications:  Ibrutinib is category D.  It should not be used in nursing 
mothers.   
 
9.2       Return and Retention of Study Drug 
Study drug will obtained by the research pharmacy at Northwestern Feinberg School of 
Medicine by prescription only.  Study drug will dispensed as needed, until next follow up.  
Therefore, we do not anticipate retention of study drug.  However, if there is unused 
study drug, it will be disposed of in an appropriate manner.  
 
9.2.1 
Compliance will be assessed by subject diary and self-report.   
 
10.0 
STATISTICAL CONSIDERATIONS 
Descriptive statistics will be completed to determine an 80% reduction in skin prick wheal size 
and basophil activation test reactivity (as determined by % inhibition of anti-IgE-induced CD63 
expression).  As this is an open label study, each patient’s responsiveness will be examined 
compared to themselves prior to initiation of treatment.  
10.1 
Study Design/Study Endpoints 
This is an open label study of ibrutnib in 12 food allergic adults to determine the shortest 
amount of time and fewest ibrutinib doses required to eliminate food SPT and BAT 
reactivity and to evaluate the effect of pretreatment with ibrutinib on food allergen 
reactivity in food allergic subjects given ibrutinib 420 or 560 mg daily for 2-7 doses.  
Given the nature of the study, it will be stopped if >50% of patients have a DLT at target 
enrollment.  
10.2 
Sample Size and Accrual 
12 subjects allows 80% power to detect a reduction in skin test positivity rate from 100% 
before treatment to 15% after treatment using a one-sided 0.05 level McNemar’s test.  
Patients will be recruited from the allergy clinics at Northwestern University Feinberg 
School of Medicine with a diagnosis of peanut (or tree nut) allergy by a board certified 
allergist-immunologist.  
 
10.3 
Data Analyses Plans 
As this is an open label trial, descriptive statistics will be used.  Each patient will be 
compared to him/herself prior to beginning treatment and at each time point in the study 
to assess SPT size (parts 1 and 2), BAT response (parts 1 and 2), and OFC threshold 
and response (part 2).

STUDY MANAGEMENT 
11.1 
Conflict of Interest 
Any investigator who has a conflict of interest with this study (patent ownership, royalties, 
or financial gain greater than the minimum allowable by their institution, etc.) must have 
the conflict reviewed by Northwestern Feinberg School of Medicine.   All investigators will 
follow the University conflict of interest policy. 


PROTOCOL                                                                                                                                                      Version: Aug 7, 2017

11.2 
Institutional Review Board (IRB) Approval and Consent  
It is expected that the IRB will have the proper representation and function in accordance 
with federally mandated regulations. The IRB should approve the consent form and 
protocol. 
 
In obtaining and documenting informed consent, the investigator should comply with the 
applicable regulatory requirement(s), and should adhere to Good Clinical Practice (GCP) 
and to ethical principles that have their origin in the Declaration of Helsinki. 
 
 
Before recruitment and enrollment onto this study, the subject will be given a full 
explanation of the study and will be given the opportunity to review the consent form. 
Each consent form must include all the relevant elements currently required by the FDA 
Regulations and local or state regulations. Once this essential information has been 
provided to the subject and the investigator is assured that the subject understands the 
implications of participating in the study, the subject will be asked to give consent to 
participate in the study by signing an IRB-approved consent form. 
 
Prior to a subject’s participation in the trial, the written informed consent form should be 
signed and personally dated by the subject and by the person who conducted the 
informed consent discussion. 
11.3 
Data Management and Monitoring/Auditing 
As has been done previously for the phase 1 study of ibrutinib (13), adverse events will 
be monitored throughout treatment and toxicities will be assessed using the National 
Cancer Institute Common Toxicity Criteria for AEs, with its latest version, currently 
version 4.03.   
11.4 
Adherence to the Protocol 
Except for an emergency situation in which proper care for the protection, safety, and 
well-being of the study subject requires alternative treatment, the study shall be 
conducted exactly as described in the approved protocol.  
11.4.1 Emergency Modifications 
Investigators may implement a deviation from, or a change of, the protocol to 
eliminate an immediate hazard(s) to trial subjects without prior IRB approval.  
 
For any such emergency modification implemented, a IRB modification form 
must be completed within five (5) business days of making the change.  
11.4.2 Other Protocol Deviations/Violations 
All other planned deviations from the protocol must have prior approval by the 
Principal Investigator and the IRB. According to the IRB, a protocol deviation is 
any unplanned variance from an IRB approved protocol that:  
 
Is generally noted or recognized after it occurs 
 
Has no substantive effect on the risks to research participants 
 
Has no substantive effect on the scientific integrity of the research plan or the 
value of the data collected  
 
Did not result from willful or knowing misconduct on the part of the 
investigator(s).  
 
An unplanned protocol variance is considered a violation if the variance: 
 
Has harmed or increased the risk of harm to one or more research 
participants.

Has damaged the scientific integrity of the data collected for the study. 
 
Results from willful or knowing misconduct on the part of the investigator(s). 
 
Demonstrates serious or continuing noncompliance with federal regulations, 
State laws, or University policies. 
 
If a deviation or violation occurs without prior approval from the Principal 
Investigator, please follow the guidelines below: 
 
Protocol Deviations: Deviations should be summarized and reported to the IRB 
at the time of continuing review. 
 
Protocol Violations: Study personnel should report violations within two (2) 
week of the investigator becoming aware of the event using the same IRB online 
mechanism used to report Unanticipated Problems.  
11.5 
Amendments to the Protocol 
Should amendments to the protocol be required, the amendments will be originated and 
documented by the Principal Investigator. It should also be noted that when an 
amendment to the protocol substantially alters the study design or the potential risk to the 
subject, a revised consent form might be required.  
 
The written amendment, and if required the amended consent form, must be sent to the 
IRB for approval prior to implementation.  
11.6  
Confidentiality 
The specimens will be coded and data will be stored in the Allergy-Immunology Research 
Labs, Mezzanine, McGaw Pavilion, or in locked file cabinets and/or on password 
protected computers.  Only the study personnel will have access to the specimens and 
data generated.  The PI and the study team members will be responsible for receipt or 
transmission of the data and specimens. The specimens will be maintained until 
exhausted or until the study ends.  If there are remaining samples at the end of the study, 
any identifying information will be removed from the sample vial and the specimens will 
be treated with 10% bleach and discarded.  Unused portions of the specimens may be 
shared with other members of the University community.  The original data will remain 
with the PI in the Allergy Division.  No PHI will be shared.  
11.7 
Provisions to Protect the Privacy Interests of Subjects 
Certain other people besides the PI and his research team may review the results of the 
study, such as administrative staff members from the Office of Research, Office of 
Research Integrity and members of the Institutional Review Board, and members of the 
Office for Human Research Protections.  There is a slight risk that a subject’s privacy 
might be at risk.  All of the above mentioned people in the respective capacities are 
obligated to protect a subject’s privacy and have training and certification in the 
safeguarding of the patient’s privacy.  All data and results will be maintained in the 
Allergy-Immunology Research Labs, Mezzanine, McGaw Pavilion, in locked file cabinets 
and/or on password protected computers. 
  
To help the subjects feel at ease, these safeguards are outlined in the consent form. 
  
As far as information in medical records, only licensed medical personnel would have 
permission to access the information. 


PROTOCOL                                                                                                                                                      Version: Aug 7, 2017

11.8 
Record Retention 
Study documentation includes all Case Report Forms, data correction forms or queries, 
source documents, Sponsor-Investigator correspondence, monitoring logs/letters, and 
regulatory documents (e.g., protocol and amendments, IRB correspondence and 
approval, signed subject consent forms). 
 
Source documents include all recordings of observations or notations of clinical activities 
and all reports and records necessary for the evaluation and reconstruction of the clinical 
research study. 
 
Government agency regulations and directives require that the study investigator must 
retain all study documentation pertaining to the conduct of a clinical trial. In the case of a 
study with a drug seeking regulatory approval and marketing, these documents shall be 
retained for at least two years after the last approval of marketing application in an 
International Conference on Harmonization (ICH) region. In all other cases, study 
documents should be kept on file until three years after the completion and final study 
report of this investigational study. 
11.9 
Obligations of Investigators 
The Principal Investigator is responsible for the conduct of the clinical trial at the site in 
accordance with Title 21 of the Code of Federal Regulations and/or the Declaration of 
Helsinki. The Principal Investigator is responsible for personally overseeing the treatment 
of all study subjects. The Principal Investigator must assure that all study site personnel, 
including sub-investigators and other study staff members, adhere to the study protocol 
and all FDA/GCP/NCI regulations and guidelines regarding clinical trials both during and 
after study completion. 
 
The Principal Investigator at each institution or site will be responsible for assuring that all 
the required data will be collected and entered onto the Case Report Forms. Periodically, 
monitoring visits will be conducted and the Principal Investigator will provide access to 
his/her original records to permit verification of proper entry of data. At the completion of 
the study, all case report forms will be reviewed by the Principal Investigator and will 
require his/her final signature to verify the accuracy of the data.

ANN & ROBERT H. LURIE CHILDREN'S HOSPITAL OF CHICAGO 
INSTITUTIONAL REVIEW BOARD 
Adult Consent to Participate in a Research Project 
Part 1 
 
Investigators at Ann & Robert H. Lurie Children’s Hospital of Chicago (Lurie Children’s) and 
Northwestern University (NU) invite you to consider participating in a research study entitled: 
 
Preventing Life-Threatening Allergic Reactions with Ibrutinib, an FDA-Approved BTK 
Inhibitor 
 
Sponsored by: The Division of Allergy and Immunology of Northwestern University and carried 
out by Anne Marie Singh, MD. 
 
This consent form describes a study being done at NU and Lurie Children’s. Research studies 
help us learn more about conditions and possible new treatments. Research studies are voluntary, 
which means that it is your choice whether to participate in the study. The study staff will also 
explain the study to you and answer any questions that you may have before you make a 
decision.   
 
WHY IS THIS STUDY BEING DONE? 
Food allergy can be a life-threatening disease, and how often it occurs continues to increase 
despite public health efforts. Studies have shown that it is less likely that a person will lose their 
food allergies over time and food allergies can also start in adulthood, so more adults now have 
life-threatening food allergies. Near fatal and fatal reactions can occur in people with food 
allergies and can cause serious situations. Even though this disease is common, there are 
currently no approved therapies for food allergy. The only thing people who have food allergies 
can do now is to stay away from the things they are allergic to and if an allergic reaction does 
happen then use an epinephrine pen when the allergic reaction happens. There is a large unmet 
need for new therapies to prevent serious allergic disease including food allergy and anaphylaxis 
(rapid and serious onset of an allergic reaction).  
 
Recently, a drug called ibrutinib was approved by the United States Food and Drug 
Administration (FDA). Although this drug is approved to treat some different forms of cancer, 
there is a possibility that this drug can also prevent allergic reactions. For this study, ibrutinib is 
considered an "investigational" drug, meaning this drug has not been approved by the FDA for 
treatment of allergies. This study is being done to determine if ibrutinib can prevent an allergic 
reaction, as well as to monitor the safety and effectiveness of the drug.  
 
The study treatment, ibrutinib, is a type of an investigational drug that is called a Bruton’s 
tyrosine kinase (BTK) inhibitor. Ibrutinib works by stopping Bruton’s tyrosine kinase, an 
enzyme (or protein that helps reactions occur) in the body that works during an allergic reaction.  
By reducing the activity of this enzyme, ibrutinib can help to control the allergic response 
associated with food allergy. Ibrutinib is in the form of a tablet and is taken by mouth and

swallowed. This is an open-label study, which means that you, the study doctor and the study 
staff will know that you will receive ibrutinib. 
 
You are being asked to participate in this research study because you have a life-threatening 
allergy to peanuts and/or tree nuts.  
 
A description of this clinical trial will be available on http://www.ClinicalTrials.gov, as required 
by U.S. Law. This Web site will not include information that can identify you. At most, the Web 
site will include a summary of the results. You can search this Web site at any time. 
 
WHAT IS INVOLVED IN THE STUDY AND HOW LONG WILL I BE IN THE STUDY? 
This study plans to enroll about 12 participants at Lurie Children’s. 
 
As a participant, you will be asked to come to the following study site for the study visits. 
 Ann & Robert H. Lurie Children’s Hospital in Chicago located at 225 E. Chicago, 
Chicago, IL 60611; Clinical Research Unit (CRU), 19th Floor 
 
If you choose to be in the study, and you qualify for the study, you will be in the study for at 
least 4 days and you will have to make  at least 3 visits to the study site. The amount of time  you 
are in the study and the number of  visits you will have may be more than this depending on how 
the study treatment works for you. You may have to take 2 to 4 doses of ibrutinib if you are in 
this study.  
 
At least 3 blood samples will be taken during the course of the study, but this may be more 
depending on how the study treatment works for you. At least 30 mL of blood (about 2 
tablespoons) will be taken at each visit. Extra blood samples may be needed  if any of your 
laboratory tests are not normal or if the study doctor thinks  it is necessary for monitoring your 
health. It is possible that more than one try to take a blood sample may be necessary. 
 
From this point on in these pages, ibrutinib will be called  the “study drug” and Ann & Robert H. 
Lurie Children’s Hospital in Chicago located at 225 E. Chicago, 19th Floor, Chicago, IL 60611; 
Clinical Research Unit (CRU), 19th Floor will be called  the “study site”. Below is a list of 
procedures that will take place at each visit while you are in the study.  
 
Schedule of Events 
 
Screening Visit (Visit 1): 
To help the study doctor determine if you are eligible to participate in this study, you will be 
asked to come to the study site for a screening visit. This visit will last approximately 1 hour. 
The following tests and procedures will be performed: 
 You will be asked to read and sign this consent form. 
 A complete physical examination will be performed and your vital signs (blood pressure, 
body temperature, breathing, and pulse rate), and height and weight will be taken.

 A review of your health and medical history, your demographics (such as your gender, 
race, and other background information), and any medications (prescription, 
nonprescription, and over-the-counter herbal and dietary) you have taken and are 
currently taking will be done. The study doctor or study staff will also review with you 
what medications you are not allowed to take during the study. 
 About 2 tablespoons (30 ml) of blood will be taken for laboratory tests (such as complete 
blood count and kidney and liver function tests).  
 You will have an electrocardiogram (ECG), which is a test that records the rhythm of the 
heart. You will be asked to lie flat on a table and several small electrode pads (like 
stickers) will be placed on the body. This test takes about 10 minutes. 
 If you are female of child-bearing potential, a urine pregnancy test will be done. 
 
Baseline Visit (Visit 2, Day 0): 
If you meet the requirements to participate in the study and agree to take part, you will be asked 
to return to the study site within 7 days or less after the screening visit (Visit 1) for your baseline 
/Day 0 visit (Visit 2). The baseline visit – Visit 2 -will last approximately 1-2 hours. The 
following tests and procedures will be performed: 
 You will have a skin prick test done. During this test, the study team will put a drop of 
solution containing the food allergen on your skin. They will use a small plastic probe or 
needle to gently scratch your skin to let the solution enter the surface. This test is usually 
not painful and will last about 30 minutes.  
 About 2 tablespoons (30 ml) of blood will be taken for laboratory tests (such as complete 
blood count, kidney and liver function tests, and tests to determine the normal level of 
substances in your blood that indicate an allergic response).  
 If you are female of child-bearing potential, a urine pregnancy test will be done. 
 You will be given a supply of study drug to take home. You will take the study drug at 
the same time every day, swallowed with a glass of water. The study staff will describe in 
more detail how to take and store the study drug at home.  
 
Study Visits 3, 4 and 5 (Days 2, 4, and 7): 
You will be asked to return to the study site for visits on Days 2, 4 and 7 (Visits 3, 4 and 5) 
following your Baseline Visit (Visit 2). If your blood tests are negative for an allergic response at 
any of these visits, then you will not take any more study drug and your next visit will be the End 
of Study Visit.  
 
These visits will last approximately 2 hours. The following tests and procedures will be 
performed at each visit except for the tests and procedures that have bold print: 
 You will have a skin prick test done.  
 About 2 tablespoons (30 ml) of blood will be taken for laboratory tests (such as complete 
blood count, kidney and liver function tests, and tests for an allergic response). 
 If you are female of child-bearing potential, a urine pregnancy test will be done (Visit 4 
or 5 only).

 You may be given a supply of study drug to take home, depending on test results for an 
allergic response. You will take the study drug at the same time every day, swallowed 
with a glass of water. The study staff will describe in more detail how to take and store 
the study drug at home (Visits 3 and 4 only).   
 
Preliminary results have shown that allergy testing is negative by Day 7.  Once allergy testing is 
negative, no further medication is given, and your participation in the study will be finished and 
you will not have any further study procedures.   
 
Weekly Follow-Up Visits/Early Termination Visit: 
Preliminary results have shown that allergy testing is negative by Day 7. If your allergy testing is 
not negative by Day 7 (Visit 5), you will be asked to return to the study site once a week for 
safety follow-up visit(s). You will be asked to attend as many visits as needed until allergic 
response testing returns to baseline (levels before  to drug treatment). Once your blood tests are 
negative for an allergic response at any of these visits, then your next visit will be the End of 
Study Visit. If you and/or the study doctor decide that you will no longer be in the study before 
your last visit, you will be asked to complete an Early Termination Visit, which will have the 
same procedures as listed below. 
 
These visits will last approximately 2 hours. The following tests and procedures will be 
performed: 
 You will have a skin prick test done.  
 About 2 tablespoons (30 ml) of blood will be taken for laboratory tests (such as complete 
blood count, kidney and liver function tests, and tests for an allergic response).  
 If you are female of child-bearing potential, a urine pregnancy test will be done. 
 
End of Study Visit: 
This will be your last visit for the study. This visit will last approximately 1 hour. The following 
tests and procedures will be performed: 
 A review of any illness or medical events you’ve had and any medications (prescription 
and over-the-counter) that have changed since your last visit. 
 A complete physical examination will be performed and your vital signs (blood pressure, 
bod temperature, breathing, and pulse rate), and height and weight will be taken. 
 About 2 tablespoons (30 ml) of blood will be taken for laboratory tests (such as kidney 
and liver function tests and tests for an allergic response).  
 You will have an electrocardiogram (ECG). 
 If you are female of child-bearing potential, a urine pregnancy test will be done. 
 
ARE THERE BENEFITS (GOOD THINGS) TO TAKING PART IN THE STUDY? 
You may or may not have any direct benefit from being in this research study. Your condition 
may or may not improve or may worsen while participating in the study. The information from 
this study might help to develop better treatments in the future for people with food allergies.

WHAT ARE THE POSSIBLE RISKS OR SIDE EFFECTS (BAD THINGS) OF THE 
STUDY? 
You might have some side effects and discomfort while participating in this research. 
 
Ibrutinib: 
All drugs may cause certain side effects and discomforts.  
The most common and expected side effects and discomforts reported for ibrutinib are:  
 Diarrhea 
 Nausea/vomiting 
 Constipation 
 Decreased appetite  
 Fatigue 
 Insomnia (trouble sleeping) 
 Headache 
 Muscle spasms 
 Other pain 
 Fever 
 Rash 
 Cough 
 Shortness of breath 
 Joint pain  
 Edema (swelling) 
 
Additional side effects have been seen in some participants given ibrutinib: 
 Hemorrhage (bleeding) 
 Infections 
 Bone marrow suppression 
 Renal (kidney) failure 
 
To date, only people with cancer have received ibrutinib.  The cancers being treated with this drug 
tend to be cancers of older adults, and most of the study subjects have been over the age of 50, 
with many aged 65 or older.  All have received drug for months to years.  Most have received 
ibrutinib after failing other treatments, or in addition to other treatments for their underlying 
cancer. In this study, you will receive a minimum of 2 daily doses and a maximum of 7 daily 
doses. 
 
Other types of cancers (range, 5 to 16%) have occurred in patients treated with ibrutinib. The 
most frequent was non-melanoma (starting at the skin’s surface, usually caused by too much sun 
exposure over many years) skin cancer (range, 4 to 13%).  In most studies, the frequency of these 
cancers was higher in those who received ibrutinib compared to those who did not, but in one 
study, the frequency of other cancers (particularly non-melanoma skin cancer) was similar in 
those who received ibrutinib versus those who did not, 24 (8%) vs 23 (8%), respectively.  The 
risk of cancer from taking 2-7 days of this drug in people without cancer is not known.

If you have any problems, you should tell the study doctor or staff as soon as possible. They will 
watch you closely. If it is best for you, the study doctor may decide to take you out of the study. If 
you are taken out of the study, the study doctor may want to continue checking on you. 
 
The study drug may have side effects that are unknown today and may include your food 
allergies getting worse. This is why it is very important for you to report any reactions or 
changes in your health to the study doctor. 
 
The study staff will monitor any side effects you have during the study. If necessary, you will be 
withdrawn from the study for your safety. 
 
Allergic Reactions: 
As with any drug, there is a risk of an allergic reaction to the study drug ingredients. It is 
important to tell the study doctor if you are having an allergic reaction. 
If you have a very serious allergic reaction, you may be at risk of death. Some things that happen 
during an allergic reaction that could be a sign or symptom of a life-threatening allergic reaction 
(anaphylaxis) are: 
 A rash (red or rough skin) 
 Having a hard time breathing 
 Wheezing when breathing 
 Sudden drop in blood pressure (making you feel dizzy or lightheaded) 
 Not able to breathe without help 
 A feeling of dread 
 Swelling around the mouth, throat, eyes or other parts of the body 
 Fast pulse 
 Sweating 
 
You should get medical help and contact the study doctor or study staff if you have any of these 
or any other side effects during the study.  
 
In the event of an emergency, dial 911 immediately. If you require emergency care, be sure to 
tell the emergency care provider about your participation in this study.  
 
Study Procedure Risks: 
 
Blood Draws: 
When a sample of your blood is taken,  you may have some temporary discomfort, pain, 
bruising, swelling and/or, in rare circumstances, infection at the needle site. Lightheadedness 
(feeling dizzy) and/or fainting may also occur during or shortly after the blood draw. 
The study staff may offer to use numbing cream (containing lidocaine, a topical anesthetic) at the 
site of your blood draw, and the study doctor can discuss with you any possible side effects of 
this cream. To minimize these risks, only trained professionals will take your blood.

Electrocardiogram (ECG): 
The sticky pads used for this test may cause skin irritation. Taking the sticky pads off causes 
discomfort similar to when taking off a band-aid. 
 
Unknown/Unforeseeable Risks: 
In addition to the risks listed above, there may be some unknown or not common  and not yet 
known risks associated with the use of this study drug, including interaction with other 
medication you may be taking. For that reason, it is very important that you tell the study doctor 
about all medications or supplements you are taking during the study. 
 
There is a risk of loss of confidentiality and/or privacy of your information. You will read more 
about the protection of your information later in this form. Please ask the study doctor if you 
would like to know more about how your information will be protected while you are 
participating in this study. 
 
ARE THERE RISKS IF I BECOME PREGNANT DURING THE STUDY? 
You should not participate in this study if you are pregnant, planning to become pregnant during 
the study, or are breastfeeding. The possible side effects to an unborn or breastfed child are not 
known at this time. Some drugs cause females to have their babies prematurely (early) or to have 
babies with birth defects. 
 
If you are sexually active, you must agree to use a medically acceptable method of birth control. 
The study doctor will talk to you about birth control methods you must use during the study.  
 
If you become pregnant while participating in the study, you must notify the study doctor or 
study staff immediately. If you become pregnant, you will have to withdraw from the study. The 
study doctor may ask for information about your pregnancy and the birth of the baby.  
The study doctor or study staff may share this information with the sponsor. 
 
All participants (both men and women) must agree to use one of the acceptable methods of birth 
control throughout the study from the Screening Visit until 90 days after stopping study drug. 
 
Birth Control:  
Birth control methods considered acceptable for this study include: 
 Abstinence  
 Oral contraceptives  
 Transdermal, intrauterine, injected, or implanted hormonal methods of contraception 
 Condom with spermicidal foam/gel/film/cream/suppository 
 Male partner with a vasectomy for at least 4 months 
 Tubal ligation 
 Surgically sterile such as hysterectomy

WHAT OTHER OPTIONS ARE THERE? 
You do not have to take part in this research study. Instead of being in this research study, you 
can follow standard of care treatments which include avoiding the allergen and the use of self-
injected epinephrine after an allergic reaction has occurred.  
 
WHAT IF MY DOCTOR OR I DO NOT THINK I SHOULD STAY ON THE STUDY? 
Your participation in this study is voluntary, and you may end participation in this study at any 
time without penalty or loss of benefits to which you are otherwise entitled. If you decide to end 
your participation, you will be asked to come into the office for an early termination visit. 
Information from this visit may be used to check on your health or for research. All the 
procedures listed under the End of Study/Early Termination Visit will be performed for the visit. 
 
The study doctor may stop your participation in this study at any time (even if you want to stay 
in the study) if he or she decides that it is in your best interest, if you do not follow study 
instructions, or if you have a severe side effect. In addition, you may be removed from the study 
if the study is cancelled by the FDA and/or the Institutional Review Board (IRB). 
 
WHAT ARE THE COSTS? 
Neither you nor your insurance company is responsible for costs associated with any tests, 
procedures and/or medications done for research purposes only. However, you and/or your 
insurance company are still responsible for the usual, ongoing medical care that is necessary to 
treat your medical condition. 
 
Since all tests and procedures are performed in this study are for research, there will be no costs 
to you for being this study. 
 
WILL I BE TOLD ABOUT NEW INFORMATION? 
We will tell you if we learn new information that may make you change your mind about being 
in this study. 
 
WILL I BE COMPENSATED FOR MY PARTICIPATION?  
You will receive $50 per each completed study visit for your time and effort and to reimburse 
you for traveling and parking costs, meals, and possible lost wages. You will be paid in the form 
of cash at the end of each study visit. 
 
If you do not complete the study, you will only be paid for the visits you complete.  
 
Due to the possible total amount of payment from this study, you will need to fill out an Internal 
Revenue Service (IRS) W-9 tax form. On this form, the Accounts Payable Office of Lurie 
Children’s or NU/NMH may collect your name, address, and social security number or 
individual taxpayer identification number (ITIN). This information is required so that the 
Accounts Payable Office can process your study payment check(s) and for income reporting 
purposes for which Lurie Children’s and/or NU/NMH are obligated by federal law to report. 
This is because under current federal tax law, the Accounts Payable Office is required to report

However, you should understand that, once your doctor or Lurie Children's releases your medical 
information outside of Lurie Children’s to these people, organizations, or companies, your doctor 
or Lurie Children's cannot guarantee that your information will remain confidential. It is possible 
that these other persons or companies could give your study information to others, without your

WHAT ARE MY RIGHTS AS A PARTICIPANT? 
By signing this consent form, you agree to take part in this study. You are not giving up any of 
your legal rights or releasing this hospital from responsibility for carelessness. 
 
You may cancel your consent and take yourself out of this study at any time. You will not be 
penalized for doing this. Your treatment by, and relations with the physician(s) and staff at Lurie 
Children’s, now and in the future, will not be affected in any way if you do not want to take part 
in this study, or if you enter into the study and then withdraw from it. 
 
At any time, you can tell your study doctor or Lurie Children's not to use or give out your study 
information or other information from your medical record to other people, organizations, or 
companies. Withdrawal of this permission must be in writing. Any study information or other 
information from your medical record collected before your written notice of permission 
withdrawal may still be used for the study, if that information is necessary for the study. Because 
the purpose of this study is to collect information about how well the study drug or treatment 
works, if you refuse to release your study information, you may not be able to start, or continue 
taking part in this study. Your decision will not affect your regular care and your doctor will not 
change his or her feelings about you. 
 
If you agree to take part in this research study, you will not be able to look at or ask for a copy of 
your health information collected only for this study, while you are taking part in the study. If 
you wish, you will be able to ask for this study research information when the study is over or 
when you are no longer taking part in the study. This does not affect your right to see your 
medical record or the results of tests related to regular medical care that is given during the same 
time as the research study. 
 
If you have any questions about the research methods, you should contact the study doctor, 
Bruce Bochner, MD, at (312) 503-0068. For questions arising evenings or weekends, you may 
call Northwestern Memorial Hospital on-call number at 312-649-3154.

research participant, and you wish to talk to someone who is not directly involved with this 
study, contact Catherine Powers, Office of Research Integrity and Compliance, 225 East Chicago
