2. Study Overview 
2A. Overall Objective  
The goal of this study is to determine whether infliximab or a second IVIG infusion abrogates fever faster 
and is associated with fewer adverse events in IVIG-resistant Kawasaki disease (KD) patients.  
2B. Study Type 
This is a Phase III, two-arm, randomized, multi-center, treatment study. 
2C. Study Population 
Infants and children with acute KD who are IVIG-resistant (fever T ≥38°C orally or rectally or 37.5°C 
axillary/ T ≥100.4°F orally or rectally or ≥ 99.5°F axillary) between 36 hours and 7 days after the end of 
the first IVIG infusion without other likely cause. 
2D. Study Duration 
 4 years  
2E. Primary Outcome  
1) Afebrile at 24h after initiation of study treatment and remains afebrile with no recurrence of fever 
related to KD in the first 7 days after discharge.  
2F. Secondary Outcomes  
1) Afebrile at 24h following completion of infusion of study treatment (i.e., infliximab or IVIG) and 
remains afebrile until discharge with no recurrence of fever related to KD in first 7 days after 
discharge. 
2) Number and severity of therapy-related adverse events according to treatment arm as adjudicated by 
the Adverse Events Committee. 
3) Change in white blood cell count (WBC), absolute neutrophil count (ANC), hemoglobin (Hgb), 
platelet count, and C-reactive protein (CRP, mg/dl) concentration between baseline (pre-IVIG at 
diagnosis), 24 hours (± 2 hours) post-end of study treatment and 5-18 days  following completion of 
study treatment  
4) Change in erythrocyte sedimentation rate (ESR) between pre-IVIG at diagnosis and 5-18 days 
following completion of study treatment 
5) Change in ZMax score (defined as the largest internal diameter of either the right coronary or left 
anterior descending arteries normalized for body surface area and expressed as standard deviation 
units from the mean) between baseline (first echocardiogram on admission) and 5-18 days  
following completion of study treatment echocardiograms  
6) Total number of fever days (24 hour period with a T≥38.0°C orally or rectally or ≥37.5°C axillary/ 
T ≥100.4°F orally or rectally or ≥ 99.5°F axillary) from enrollment  
7) Duration of hospitalization  
8) Number and severity of study treatment infusion reactions 
9) Requirement for additional anti-inflammatory therapies after crossover failure 
10) Comparison of patient/parent-reported outcomes (PROs) by study arm through the use of a parent 
observation tool to record discomfort, psychosocial concerns, and other experiences of treatment 
during the child’s in-hospital stay and outpatient course.

3. Background, Significance, and Rationale 
3A. Significance 
Kawasaki disease (KD) is a self-limited vasculitis of unknown etiology that is the most common cause of 
acquired heart disease in children (Newburger et al. 2016). Intravenous immunoglobulin (IVIG) reduces the 
incidence of coronary artery aneurysms (CAA) from 25% to approximately 5% (Newburger et al. 1986). 
However, for the 10-20% of IVIG-resistant patients (defined as having T≥ 38.0°C at least 36h following 
the end of the IVIG infusion), there is no evidence-base to guide treatment and this group has an increased 
risk of coronary artery aneurysms. In our study of 362 consecutive KD patients, 9 of 60 IVIG-resistant 
patients (15%) versus 9 of 302 (3%) developed CAA (Tremoulet, Best et al. 2008). Recent data from Japan 
suggests that the rates of IVIG-resistance have risen from 7% in 2003 to 23% in 2014 with a concomitant 
increase in CAA (Kibata, Suzuki et al. 2016). 
 
3B. Rationale   
 
There is clinical equipoise regarding the best treatment for IVIG-resistant patients and either a second 
infusion of IVIG or infliximab (a monoclonal antibody that blocks the pro-inflammatory cytokine tumor 
necrosis factor (TNFα) is the most common second treatment (Sundel, Burns et al. 1993, Burns, Capparelli 
et al. 1998, Burns, Best et al. 2008, Son, Gauvreau et al. 2011). Some centers also treat with steroids (Yang, 
Liu et al. 2015). The American Heart Association (AHA) KD guidelines assign an Evidence level of C 
(Consensus opinion of experts) to re-treatment with either second IVIG or infliximab (Newburger, 
Takahashi et al. 2004). However, the stakes are high for this subgroup of patients as CAA due to persistent 
inflammation constitutes permanent damage to the arterial wall with an associated risk of myocardial 
infarction, arrhythmias, or sudden cardiac death (Kato, Sugimura et al. 1996, Gordon, Daniels et al. 2016). 
 
For this trial, the dose of infliximab will be 10 mg/kg IV. A Phase III clinical trial of adjunctive primary 
therapy with infliximab at 5 mg/kg demonstrated that infliximab is safe and well-tolerated even in infants 
less than 6 months of age (Tremoulet, Jain et al. 2014). Further study of KD patients enrolled in this trial 
demonstrated that pre-treatment soluble TNFα receptor 1 (sTNFR1) levels are elevated in acute KD and are 
higher in KD patients with CAA compared to those with normal CA. At 24 hours following infusion of 
infliximab 5 mg/kg, KD patients with CAA had lower levels of free (unbound) infliximab compared to 
those with normal CA. These data suggest that 5 mg/kg of infliximab may be insufficient for many KD 
patients and thus a single dose of 10 mg/kg of infliximab is warranted for this study. Infliximab at a dose of 
10 mg/kg has been used at RCHSD for the treatment of 88 acute KD patients with either CAA or IVIG-
resistance with no adverse events related to this therapy.  
 
4. Study design  
 
4A. Research Design Overview 
KIDCARE is a 4-year (3.75-years of enrollment), Phase III, two-arm, randomized, multi-center, treatment 
study to compare infliximab to a second intravenous immunoglobulin (IVIG) infusion for treatment of 
persistent or recrudescent fever in children with KD who fail to become afebrile after the first IVIG 
infusion at collaborating clinical sites (see Appendix A).

4B. Inclusion 
1) 4 weeks to < 18 years of age,  
2) Meets American Heart Association (AHA) criteria for KD by one of the following:  
a. Four of five clinical KD criteria (see Table 1) 
b. Meets 2017 AHA criteria for incomplete KD  (see Table 2)  
3) Fever by parental history for 3 to 10 days prior to initial IVIG treatment 
4) Fever (T ≥38°C orally or rectally or ≥37.5°C axillary/ T ≥100.4°F orally or rectally or ≥ 99.5°F 
axillary) between 36 hours and 7 days after end of the first IVIG infusion that is more likely than not 
related to KD in the opinion of the Site PI or Co-investigator 
 
Table 1. Diagnostic criteria for KD with CAA (Adapted from American Heart Association 
2017 guidelines) 
KD standard clinical criteria: 
 Bilateral conjunctival injection 
 Changes of the mucous membranes of the upper respiratory tract: injected pharynx, 
injected, fissured lips, strawberry tongue 
 Changes of the peripheral extremities: peripheral edema, peripheral erythema, periungual 
desquamation 
 Polymorphous rash 
 Cervical adenopathy >1.5 cm

Table 2.  AHA Criteria for incomplete KD (McCrindle et al., Circulation, 2017) 
 
(1) In the absence of a “gold standard” for diagnosis, this algorithm cannot be evidence based but rather represents the informed 
opinion of the expert committee. Consultation with an expert should be sought any time assistance is needed. (2) Clinical findings 
of Kawasaki disease are listed in Table 3. Characteristics suggesting that another diagnosis should be considered include 
exudative conjunctivitis, exudative pharyngitis, ulcerative intraoral lesions, bullous or vesicular rash, generalized adenopathy, or 
splenomegaly. (3) Infants ≤6 months of age are the most likely to develop prolonged fever without other clinical criteria for 
Kawasaki disease; these infants are at particularly high risk of developing coronary artery abnormalities. (4) Echocardiography is 
considered positive for purposes of this algorithm if any of 3 conditions are met: Z-score of left anterior descending coronary 
artery or right coronary artery ≥2.5; coronary artery aneurysm is observed; or ≥3 other suggestive features exist, including 
decreased left ventricular function, mitral regurgitation, pericardial effusion, or Z scores in left anterior descending coronary 
artery or right coronary artery of 2 to 2.5. (5) If the echocardiogram is positive, treatment should be given within 10 days of fever 
onset or after the tenth day of fever in the presence of clinical and laboratory signs (C-reactive protein [CRP], erythrocyte 
sedimentation rate [ESR]) of ongoing inflammation. (6) Typical peeling begins under the nail beds of fingers and toes. ALT 
indicates alanine transaminase; and WBC, white blood cells 
 
4C. Exclusion 
1) Patient treated with infliximab or steroids for present illness (e.g. RAISE protocol) (NB. patients who 
received oral steroids as outpatients prior to KD diagnosis (e.g. for suspected allergic reaction) but who 
otherwise qualify for the study will not be excluded) 
2) Known prior infection with tuberculosis, coccidiomycosis, or histoplasmosis. 
3) Household member with active TB. 
4) Use of a TNF-α  blocker within the 3 months prior to enrollment 
5) Have any chronic disease, except asthma, atopic dermatitis, autism or controlled seizure disorder  
6) Patient has a history of hypersensitivity to infliximab or antibodies derived from murine cells 
4D. Study Sites and Target Enrollment 
Subjects will be enrolled at participating sites over 3.75 years and randomized to infliximab or 2nd IVIG. 
Target enrollment will be 112 subjects (56 subjects/arm). We anticipate an enrollment of 0-15 subjects/year 
per participating site.

4E. Dosing Protocols 
1. Second IVIG  
All subjects randomized to receive a second dose of IVIG as their first study treatment will receive 2g/kg 
IV over 8-12 hours. The start and stop times, as well as the brand of IVIG administered, will be recorded 
on the Study Drug Administration form on REDCap. Premedication is not recommended but its use will 
be at the discretion of the site PI. If premedication is used, this drug name, dose, route, and time 
administration must be recorded on the Concomitant Medication form on REDCap. 
2. Infliximab 
All subjects randomized to receive infliximab will receive 10 mg/kg intravenously over a minimum of 2 
hours. The start and stop times will be recorded on the Study Drug Administration form on REDCap. 
Premedication is not recommended but its use will be at the discretion of the site PI. If premedication is 
used, this drug name, dose, route, and time of administration must be recorded on the Con Med CRF. The 
FDA does not require a PPD or Quantiferon® testing prior to single dose administration of infliximab to 
KD patients given that the majority are anergic during the acute illness. A CXR is no longer a requirement 
prior to single dose infliximab administration for treatment of KD. 
N.B. Documentation of a concomitant viral infection by PCR or other methods should not be considered a 
contraindication to receiving infliximab.  
3. Aspirin 
All subjects should receive 30-50 mg/kg/day divided every 6 hours following randomization until the 
time of discharge. Centers may use 80-100 mg/kg/day but are encouraged to adopt the more moderate ASA 
dosing of 30-50 mg/kg/day. Upon discharge or in the event of initiation of dual anti-platelet therapy in a 
subject with aneurysms, the dose of aspirin (ASA) will be lowered to 3-5 mg/kg/day and administered as 
either 40.5 mg or 81 mg aspirin once daily.  ASA will be continued at least until the end of the study 
(follow-up visit) and discontinued thereafter at the center PI’s discretion. This medication will be recorded 
on the Concomitant Medication form on REDCap. It will also be recorded on the Temperature 
Measurement form.  You will need to record the date and time of the Aspirin given before the temperature 
was taken.   
4F. Discharge from the Hospital 
A subject who is afebrile at 24h after the completion of study drug administration may be discharged from 
the hospital as long as 24 hours have elapsed from the completion of the study treatment to ensure that 
outcome measures and laboratory studies are obtained. 
 
4G. Temperature measurement by parents during first 7 days after discharge 
Sites will receive thermometers to give to the parents at the time of discharge for at home measurement of 
axillary temperatures once/day for the first 7 days following discharge. The daily Twilio contact will ask 
the parent for the first 7 days only if their child had a fever and the answer will be recorded. The parent will 
be prompted each day for the first 7 days to contact their study doctor if a fever is documented (T ≥37.5°C / 
T ≥ 99.5°F axillary). Causality of any recurrent fever will be adjudicated by the site PI and will be 
designated as related (more likely than not) or unrelated to KD.

5. Data Collection 
 
***All data from hospitalization must be entered into REDCap within a week of patient discharge 
and all data from follow-up visit no later than one week after the visit*** 
 
All Forms are located in Appendix C. 
5A. Tracking Total Number of KD Patients at each Site 
Each site will be responsible for maintaining a log of the total number of KD patients seen at their site 
during the study period. For each site, this log will need to be maintained from the time the site was opened 
for enrollment in KIDCARE until the closure of enrollment. It will include the date of KD onset for each 
patient seen at your site. This information will NOT be entered into the REDCap database but will be 
requested by the Program Manager at Coordinating Center, Samantha Roberts (sroberts@ucsd.edu), via 
email every month. 
5B. Obtaining a REDCap account 
Each approved site’s research team needs to get access to the KIDCARE REDCap database.   Once you 
have been IRB approved, Samantha will set up a call with each member of your team to start the process of 
access.  Below are the steps that need to be taken: 
University of California San Diego (UCSD) Active Directory (AD) Account:  
Samantha will need to set up a call with each individual member of the research team.  To get an AD 
account with UCSD, each member will have to give Samantha the following information: the last 4 of their 
Social Security Number, month of birth, and day of birth. This information is submitted securely to UCSD.  
Each member will then receive an email from UC Health Service Management that will include their AD 
account username and their temporary password.  All passwords much be changed immediately. 
 
How to change your UCSD AD account password 
 
1. Go to -> https://password.ucsd.edu/ 
2. Choose “I know my current AD password and would like to change it” 
3. Your password needs to be:

5E. Eligibility Evaluation Form and Informed Consent 
Study participation will be offered without regard to age, sex, or ethnic background. Child assent will be 
obtained for all study patients ≥ 7-12 yrs. and adolescent assent will be obtained for patients 13-17 yrs. 
Recruitment of human subjects with written Informed Consent will be obtained by study personnel in the 
hospital inpatient units. There are occasions when no study personnel are available in the hospital, in which 
case one of the co-investigators is contacted by telephone.  The Parent (child/ adolescent if applicable) is 
provided with the written consent form and HIPAA authorization by hospital personnel and the co-
investigator reviews the written informed consent document(s) over the phone and answers any questions.  
The parent (child/adolescent if applicable) then signs and dates the consent document (s) and the witness 
signature is obtained at a later time from the co-investigator who obtained the informed consent.  The 
Parent (child/ adolescent if applicable) will be provided with the signed written consent form and HIPAA 
authorization. 
 
Screen Fails:  All subjects who meet the AHA criteria for complete or incomplete KD and who had a 
fever (T ≥38°C orally or rectally or 37.5°C axillary/ T ≥100.4°F orally or rectally or ≥ 99.5°F axillary) 
between 36 hours and 7 days after the end of the first IVIG infusion without other likely cause will be 
included in the REDCap database. Some KD subjects who have a fever between 36 hours and 7 days 
after the end of the first IVIG infusion will not be eligible for the study because the subject did not meet 
entry criteria or the family refused to participate in this study.  These subjects who have been screened for 
study participation, will have their screening information entered into the eligibility evaluation form 
REDCap without consent being obtained. This de-identified information is collected to understand why 
patients either were not eligible or refused participation for the study.  All the information entered into the 
REDCap database is de-identified.

5I. Enrollment Temperature Measurement/Temperature Measurement Form  
The preferred routes for measuring the temperature are oral and rectal. A fever will be considered T ≥38°C/ 
T ≥100.4°F rectally or orally. Sites that are unable to obtain core temperatures via these routes can use 
axillary temperatures as an alternative with T ≥ 37.5°C/ T ≥ 99.5°F   axillary considered to be a fever. 
While other methods can be used (temporal wand, tympanic temperature, etc.) to monitor patients, 
temperature time points (see below) required for the study MUST BE DOCUMENTED BY EITHER 
ORAL, RECTAL OR AXILLARY ROUTES.  If another method was used for a key time point, enter that 
value with a comment on methods. If you do not use one of the preferred methods, completed the Protocol 
Deviation form on REDCap. Please work with your nursing staff to explain the importance of correct 
temperature measurement. 
 
Temperature, route of measurement, date, and time (24h clock) for the following time points: 
a. Qualifying temperature at study entry and route (Centigrade or Fahrenheit) 
b. 24 hours (±2h) from initiation of study treatment;  
c. 24 hours (±2h) from completion of study treatment 
d. If 2nd  study treatment administered, i-iii above for 2nd study treatment

5L. Center Echocardiogram Form 
An echocardiogram will be performed at the following time points per standard of care:  
i. 
During initial hospitalization at the time of diagnosis (If multiple 2-D echoes are obtained on a 
given patient prior to diagnosis, then the echo closest to the time of the first IVIG infusion 
should be used on Echocardiogram Form ) 
ii. 
Capturing the worst ever echo between echo closest to 1st IVIG and echo at follow-up visit 
iii. 
5-18 days following the completion of study (follow-up visit) 
 
2-D transthoracic echocardiograms (2-D Echo) will be performed on all KD subjects according to a 
standardized protocol recommended by the Pediatric Heart Network and the AHA. 2-D Echo will be 
performed at KD diagnosis (preferably within 24h of first IVIG infusion prior to study enrollment) and 
again at two weeks (± 4 days) following enrollment. Sedation for children younger than 3 years is 
recommended. The patient’s height and weight and internal lumen diameters in millimeters of the left main 
(LMCA), proximal LAD, circumflex, and proximal and mid RCA will each be measured and recorded on 
the CRF. Dimensions of the LMCA, proximal LAD, circumflex, and proximal RCA will be adjusted for body 
surface area and expressed in standard deviation units (Z-scores) at the Coordinating Center.  
 
Weight of subject should be measured with shoes off.  We recommend that height is measured by a nurse 
and confirmed by a second nurse using a stadiometer.

a) Total number of fever days (24 hour period with a T ≥38°C orally or rectally or ≥37.5°C 
axillary/ T ≥100.4°F orally or rectally or ≥ 99.5°F axillary) from the time of start of infusion 
of first study treatment. A day is from 12:01 am to 12:00 midnight. Example: If the patient 
starts first study treatment at 1:00 am and becomes afebrile at 11:00 pm that night, then that 
is one fever day. If fever returns two days later at 1:00 am and the patient receives second 
study treatment and becomes afebrile at 11:00 pm that night, then this counts as another 
fever day.  The total number of fever days this patient will have had is 2.

5O. Patient Observation Tool 
After discharge subjects will be monitored for 2 weeks to evaluate for adverse events. The UC Davis team 
(Kathy Kim and Sakib Jalil) developed an instrument that will be presented as a survey either via email to 
the parents/legal guardians. Parents/legal guardians will have the option to choose between paper or email 
as their preferred way of reporting. Their preference will be recorded on p. 6 of the observation tool form in 
Appendix B. During the 2 weeks following discharge, parents/legal guardians will be prompted to complete 
the survey once each day. Any medical conditions reported by the parents (e.g. recurrent fever, 
arthritis/arthralgia interfering with ambulation, new-onset rash) will prompt a message to the parent to 
contact their study doctor. A reminder message is included in the daily contact for the first week only after 
discharge reminding parents to call the study physician if fever has recurred. 
 
Name of forms: 
a) Baseline Observation Tool (Start of Study Treatment) 
b) 8-hour Observation Tool 
c) 16-hour Observation Tool 
d) 24-hour Observation Tool 
 
Parents and legal guardians will complete the Parent Observation Tool to record observations about their 
child. The paper copy of the form must be given to the responsible adult by the site study doctor at the time 
of randomization. The parent/guardian will complete this form at four times during the first 24-hour period 
that their child is in the study: 
 
The four time points for completion of the observation tool while in the hospital are: 
1. Before start of study treatment 
2. Around 8 hours after start of 1st study treatment 
3. Around 16 hours after start of treatment 
4. Around 24 hours after start of treatment. 
If a child receives a second study treatment as a cross-over in the protocol, the parent/legal guardian will 
complete the tool for an additional 24 hours. 
1. Around 8 hours after start of second study treatment 
2. Around 16 hours after start of second treatment 
3. Around 24 hours after start of second treatment 
 
The observation tool is attached as Appendix B.  Note that there are 7 pages to the tool.  Provide pages 1-6 
to the parent.  Page 7 is an example of the monitoring questions that will be collected at home and is for the 
study team reference only. If you have any questions about the this observation tool you can contact the UC 
Davis team by calling Katherine Kim at 510-761-5406 or emailing Katherine at kathykim@ucdavis.edu. 
 
The parent should return the form to the site study physician/coordinator after completing of all 
time points and prior to discharge from the hospital. The site study physician/coordinator will enter 
the data into REDcap forms: Baseline Observation Tool (Start of Study Treatment), 8-hour 
Observation Tool, 16-hour Observation Tool, 24-hour Observation Tool Follow the instructions 
above to enter these data into REDCap.  

 
54 
10/14/2019 
 
 
On the day of hospital discharge, call the 24h-monitored phone number at UC Davis (510-761-5406) and 
leave a message with the following information so that team can schedule the monitoring emails to be sent 
to the family starting the day after discharge.   
 
When you call, please provide:  
1. Subject study ID 
2. Date of the call 
3. Parent’s preferred email  
4. Your name  
5. Your contact information  
  
If the parent chooses paper, please collect the paper questionnaire at the follow-up visit.  Then scan and 
email the completed questionnaire to Samantha Roberts at sroberts@ucsd.edu. 
 
Compensation for Participation 
On completion of the parent observation daily observations, subjects will be provided with a $25 gift card 
at the follow-up visit to offset any incidental expenses for participation. The gift cards will be supplied by 
the UC Davis team to all sites at study initiation. Requests for additional cards should be made to calling 
Samantha Roberts at 858-966-8799 or email sroberts@ucsd.edu.

5P. Adverse Event Reporting From 
1. Risks associated with second IVIG treatment 
1) Infusion reaction: Usually occurs during the first 1-2 hours of the infusion and is characterized by a 
sudden rise in temperature accompanied by rigors, hypotension, and distress. Caution must be 
exercised not to confuse fever from KD with fever and systemic signs associated with an infusion 
reaction. Treatment for a reaction is to stop the infusion, administer acetaminophen (15 mg/kg) and 
diphenhydramine (1mg/kg), and resume the IVIG infusion at half the rate at which the reaction 
occurred. Once the infusion is tolerated, the rate can be increased per standard nursing protocols. 
There are no published data re: frequency of this reaction with the second IVIG infusion. The rate is 
10-15% for the first infusion. In our previous infliximab clinical trial, none of 22 subjects receiving 
a second IVIG infusion had a reaction. 
2) Pain and tenderness at the infusion site. IVIG extravasation (pH 4.0) from a leaking IV can cause a 
3rd degree burn. 
3) Headache (13%)(Stiehm 2013) 
4) Abdominal pain (<5%) 
5) Sterile meningitis (<1%)(Orbach, Katz et al. 2005) 
6) Hemolytic anemia due to titers of anti-A and anti-B blood groups in the IVIG preparation. This is 
an emerging problem among treated patients with A, B, or AB blood types (3% in our experience at 
RCHSD) (Berard, Whittemore et al. 2012) 

 
57 
10/14/2019 
 
2. Risks associated with infliximab treatment 
1) Reactivation of latent mycobacterial or fungal infection: History of known TB, histoplasmosis, or 
coccidiomycosis would exclude subject from participating in the trial. Theoretically, an 
unrecognized latent infection with these agents could be converted to an active infection, although 
this has not been reported following a single dose. 
2) Infusion reactions (<1% for 1st infusion) 
3. Adverse Events 
An adverse event is any untoward medical occurrence experienced by a subject. An event constitutes a 
disease, a set of related symptoms or signs, or a single symptom or sign. 
 
 Adverse Events (AE) will be recorded according to the date and time of first occurrence, severity, and their 
duration, as well as any treatment, prescribed. Following initiation of study treatment, all new or continuing 
adverse events that were not present at enrollment will be recorded. Any medical condition present at the 
initial visit, which remains unchanged or improves, will not be recorded as an adverse event at subsequent 
visits. However, worsening of a medical condition that was present at the initial visit will be considered a 
new adverse event and reported. Abnormal laboratory values, if felt by the investigator to be clinically 
significant, will also be recorded on the AE form and assessed in terms of severity and relationship to study 
drug. Laboratory values that are abnormal at study entry and that do not worsen will not be recorded on the 
AE form.  The Adverse Events Committee will adjudicate the adverse events and determine if the event 
was ‘Not Related’, ‘Possible Related” or “Probably Related” to the study treatment.  The members of the 
Adverse Events Committee are Jane Burns, Adriana Tremoulet, Jane Newburger, and Anne Rowley 
 
The following will NOT be considered adverse events as these are commonly associated with KD: 
Neutropenia at follow-up visit when patients typically develop lymphocytic predominance 
Periungual desquamation 
Thrombocytosis 
4. Serious Adverse Events 
An SAE is defined as any event which:  
1. Is fatal; or  
2. Is life-threatening (the patient was, in the view of the Principal Investigator, in immediate danger of 
death from the event as it occurred); or  
3. Requires hospital admission or prolongs hospitalization; or  
4. Is persistent or causing significant disability; or  
5. Required medical intervention, such as major surgery, to prevent a serious outcome; or  
6. Is associated with a  congenital anomaly 
7. The Clinical Site Principal Investigator considers it to be a serious adverse event.  
 
SAEs for this trial include but are not limited to, prolonged hospitalization due to study treatment 
crossover, anaphylaxis, arrhythmia, cardiac arrest, cardiogenic shock, death, hearing loss, myocardial 
infarction, renal failure, seizures, sepsis (confirmed), or serious infection requiring hospitalization.  
 
Reporting Unanticipated Problems involving risk to subjects or others (URPs)  
What to report. The following events meets the definition of a URP and should be reported to Samantha 
Roberts (sroberts@ucsd.edu) within 5 working days: 

 
58 
10/14/2019 
 
a) Any serious adverse event (SAE) (including injured, side effects, deaths or other problems) 
that in the opinion of the Principal Investigator was unanticipated, involved risk to subjects 
or others, and was at least possibly related to the research procedures.  
b) Any serious accidental or unintentional change in the IRB-approved protocol that alters the 
level of risk 
c) Any deviation from the protocol taken without prior IRB review to eliminate apparent 
immediate hazard to a research subject 
d) 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 of the research 
e) Any breach in confidentiality that may involve risk to the subject or others 
f) Any complaint of a subject that indicated an unanticipated risk or that cannot be resolved by 
the Principal Investigator 
 
 
Problems/events that are unanticipated and serious should be reported to the Samantha Roberts 
(sroberts@ucsd.edu) within 5 working days only if in the opinion of the Principal Investigator they are 
possibly, probably or definitely related to the research procedures. Those serious, unanticipated 
problems/events that the Principal Investigator deems unlikely or not related do NOT meet the IRB’s 
definition of UPRs; however, these events must be reported to the IRB at least annually at the time of 7-

 
59 
10/14/2019 
 
year “re-submission” or Continuing Review submission. Please report these events in the Adverse Event 
Form.  
 
Serious Adverse Events (SAEs) need to be entered into REDCap within 5 days of occurrence.  PCORI 
requires us to report all SAEs within 10 working days.  
Hemolytic Anemia  
This is a serious adverse event that can happen to subjects who are randomized to receive a second dose of 
IVIG.  Subjects with A ,B, or AB blood types are at higher risk to get hemolytic anemia.  If a subject is 
diagnosed with hemolytic anemia, please complete the Adverse Event Reporting form as well as the 
Hemolytic Anemia AE form.  The hemolytic anemia form includes some additional information that is 
collected once a patient is diagnosed with hemolytic anemia.  Not all of the requested information is 
required, but strongly suggested as a work up of hemolytic anemia in patients with KD.  Please include 
whatever information is standard of care at your institution for the work up of hemolytic anemia.   
 
Here is a list of the information we are requesting: 
 Blood Type 
 Creatinine 
 Total and direct bilirubin 
 Plasma hemoglobin 
 Urine hemoglobin 
 Haptoglobin 
 CBC with reticulocyte count 
 Direct and indirect antiglobulin test 
 Blood smear

6. Additional Therapy 
6A. Crossover treatment  
Subjects with a fever (T ≥38°C orally or rectally or ≥37.5°C axillary/ T ≥100.4°F orally or rectally or ≥ 
99.5°F axillary) at 24 hours after completion of 1st study treatment will cross-over to receive the other study 
treatment.  You will need to document this in REDCap. This is also considered a Serious Adverse Event 
(SAE), since this additional treatment will prolong the hospitalization of the subject.  You will need to 
complete the following forms: 
 
1) Crossover Drug Administration Form 
2) Crossover Temperature Form 
3) Crossover Laboratory Results Form 
4) 8, 16, 24hr Observation Tool 
5) Adverse Event Reporting form 
  
6B. Management of Treatment-resistant Subjects 
Treatment-resistance will be defined as persistent or recrudescent fever (T ≥38°C orally or rectally or 
≥37.5°C axillary/ T ≥100.4°F orally or rectally or ≥ 99.5°F axillary) ≥ 24 hours and <7 days following 
completion of infusion of the 2nd (crossover) study treatment. Subjects who meet criteria for treatment-
resistance will be treated at the Center PI’s discretion. Treatments will be recorded on the Concomitant 
Medication Form. 

 
72 
10/14/2019 
 
6C. Additional Therapy for Coronary Artery Abnormalities  
Additional therapy for coronary artery abnormalities will be at the Center PI’s discretion. If possible, 
additional anti-inflammatory therapies (steroids, cyclosporine, cyclophosphamide) should be avoided. 
However, if clinically indicated in the opinion of the Center PI, the subject should remain on study and all 
ancillary treatment should be recorded on the Con Med CRF. Cardiac medications (B-blockers, enoxaparin, 
dobutamine, etc.) are administered at the discretion of the Center PI and recorded on the Con Med CRF. 
6D. Allowable concomitant medications 
The following medications may be given after patient enrollment into the study: 
1) Acetominophen: may be administered for documented fever but should NOT be given to treat pain 
(e.g. headache, joint pain) during hospitalization. If administered at home while on study, parent 
should be queried about medication usage and this should be documented at the follow-up visit. 
2) Naproxen: may be administered for arthralgia/arthritis, suggested dose of 15 mg/kg/day divided 
q12h for 5 days; suspend aspirin therapy while on naproxen. This therapy may mask fever and 
should only be used when clearly clinically indicated. 
3) Opioids: may be administered for pain 
This information will be entered into REDCap at the following time points (Appendix C):   
1) Enrollment 
2) 24 hours post imitation of study treatment 
3) 24 hours post completion of study treatment 
4) Follow-up study visit 
5) Any other time from enrollment to the follow-up study visit

8. Statistical Considerations 
8A. Power and Sample Size Justification 
The study is sufficiently powered for a superiority clinical trial. For the primary endpoint, if we assume 53 
evaluable subjects per group (total N=106) in this 2-arm trial, we will have 80% power to detect a 
difference between the group proportions of 0.155.  We assume that the reference group proportion (i.e. 
2nd IVIG arm is 67%, i.e. 8 of 12 patients responding will be similar to our published clinical trial (Burns, 
Best et al. 2008). The infliximab arm proportion is assumed to be 89% (based on published clinical trial, 
i.e. 11 of 12 patients responding). The power was computed for the case in which the actual infliximab 
arm proportion is lower at 82.5%.  Statistical power is based on a two-sided, two sample binomial test for 
proportions, and a two-sided alpha=0.05 was used. Subjects will be in the study for two weeks following 
administration of study drug and there is a possibility that subjects could be lost to follow-up. Assuming 
5% attrition, we will need to enroll 112 subjects to get 106 evaluable patients.  
8B. Statistical Analysis Plan 
This section briefly describes the planned statistical analysis. The Statistical Analysis Plan (SAP) provides 
details. In case the language in this section differs from the language in the SAP, the SAP takes precedence.  
The SAP will be finalized prior to the study’s database lock.   
 
Since this is a superiority study design, an intent-to-treat (ITT) analysis will be used to analyze the outcome 
data regarding patient outcomes. Results will be reported as point estimates (odds ratios or mean 
differences across groups, as appropriate) and interval estimates (95% confidence intervals).  All tests of 
significance for the secondary outcomes will be 2-sided and Hochberg adjustments will be made for 
multiple comparisons.  A p-value ≤ 0.05 will be considered statistically significant.  Statistical analysis will 
be conducted using the statistical software R 3.3.2. (www.rproject.org).  Demographic and baseline 
characteristics will be compared between the study arms using Fisher’s exact test for categorical variables, 
and a two-sample t-test for continuous variables.  Appropriate non-parametric alternatives will be 
considered, if parametric assumptions fail.  There will be no planned interim analyses for efficacy or 
futility conducted for this study, but the Data and Safety Monitoring Board (DSMB) may modify this 
during ongoing safety monitoring. 
 
Analysis of Primary Outcome:  
The primary outcome (Specific Aim 1) of the study is cessation of fever within the specified time frame, 
which is a dichotomous (binary) variable.  Comparison between the infliximab and second IVIG arms will 
be compared using a Fisher’s exact test for proportions. Differences in the rates between the two groups, 
along with the odds ratio (OR) and their 95% confidence intervals will be reported.  As a 
secondary/sensitivity analysis, multivariable logistic regression analysis will be performed to study the 
association between clinical and demographic factors (age < 1 yr., sex, ESR, WBC, ANC, CRP) and 
intervention arm, adjusting for baseline demographic, stratification variables, and clinical characteristics. 
Variables significantly associated with both treatment group and outcome (p<0.10) will be included in a 
multivariable logistic regression model as covariates.  
 
 

 
74 
10/14/2019 
 
Analysis of Secondary Outcomes:   
The first secondary outcome will test the hypothesis that infliximab treatment will result in more rapid 
resolution of inflammation compared to second IVIG as measured by WBC, ANC, and levels of CRP at 24 
hours and 5-18 days following completion of study treatment. We cannot make power estimates for this 
secondary aim as there are no prior data to guide assumptions. Comparisons between the Infliximab and 
second IVIG arms will be compared using a two-sample, two-sided t-test at each time point separately. 
Point estimates and their 95% confidence intervals will be reported.  As a secondary/sensitivity 
analysis, multiple linear regression at each time point will be performed to study the association between 
clinical and demographic factors (age < 1 yr., sex, ESR, WBC, and ANC) and intervention arm, adjusting 
for baseline demographic, stratification variables, and clinical characteristics, including baseline CRP. 
Variables significantly associated with both treatment group and outcome (p<0.10) will be included in a 
multiple regression model as covariates. Appropriate non-parametric alternatives will be considered, if 
parametric assumptions fail. A mixed model repeated measures (MMRM) model with three repeated 
measures (baseline, 24 hours, and at 5-18 days following completion of study treatment) will evaluate 
changes between the study arms for the major dependent variables, i.e. WBC, ANC, and CRP. Participants 
will only be included in the MMRM model if they have both a baseline and at least one post-baseline 
measurement. The model will include as the dependent variable the change from baseline in the 
inflammation variable at each post-baseline visit for each dependent inflammation marker separately.  
Independent variables in the MMRM model will include treatment arm, visit, treatment arm-by-visit 
interaction, the inflammation variable at baseline and other covariates. Visits will be treated as a categorical 
variable. Unstructured variance-covariance structure will be used. 
 
Analysis of Secondary Outcomes:  
This secondary outcome (Specific Aim 3) will test the hypothesis that infliximab treatment will result in a 
change in coronary artery Zworst score of ≥ 0.5 standard deviation units as compared to second IVIG at 5-
18 days following completion of study treatment measured by echocardiography. We cannot make power 
estimates for this secondary aim as this there are no prior data to guide assumptions.  Methods analogous to 
the analysis of Specific Aim 2 will be applied, including t-tests and regression models. There is a concern 
about inter-rater reliability of different readers for the echocardiograms at the 25 sites. Inter-rater reliability 
analysis will be conducted using Cohen’s Kappa statistics and multi-level modeling to measure agreement.  
In addition, to minimize disagreement, the Coordinating Center has developed manuals used in previous 
clinical trials to help standardize performance of echocardiograms and the measurement of the coronary 
arteries. During the run in period, a de-identified echocardiogram on a KD patient will be submitted to the 
coordinating center at UCSD and the quality will be assessed and feedback given to the center PI. 
 
Analysis of Parent Observation Tool:  
We have already engaged the advisory board in development of this aim beginning with the pSCANNER 
grant in 2015.  Within the first two months of this project, we will conduct in-depth, semi-structured 
interviews of 6 parents who have recently had a child treated with IVIG and treated with infliximab to 
further understand the experience of the different treatments and confirm PROs of relevance to 
patients/parents. Qualitative analysis will be performed using a grounded theory approach to inductively 
develop themes (Charmaz 2006, Corbin and Strauss 2014). The research team and advisory board will 
create questions that represent the categories of themes. The questionnaire will then be pre-tested with 6 
KD parents with children recently treated for KD at UC San Diego or UC Davis  for logic and clarity using 
cognitive interviewing by phone (Beatty and Willis 2007). The questionnaire will be implemented with 
parents whose children are enrolled in the trial in order to compare the PROs and experience of treatment.  
The questionnaire responses will be numerically tabulated overall and by study arm. The results of the 
analysis will be summarized descriptively (point estimates and confidence intervals). The amount of 

 
75 
10/14/2019 
 
missing data will also be evaluated and compared between study arms. Comparisons by study arm will be 
evaluated by a two-sample t-test if parametric assumptions hold.  If the assumptions are violated, we will 
compare treatment arms by the Wilcoxon rank sum test.  No adjustments for multiple comparisons will be 
made, since the questions will be determined a priori as the questions of interest that will determine 
parental preference to the treatment arms. In addition, multiple regression (Likert scaled items) and logistic 
regression (binary items) will be applied to assess the contribution of demographic factors, e.g. age of child 
and parent, and experiential factors, e.g. previous illnesses, on the ratings of items. Open-ended questions 
will be analyzed with thematic content analysis based on grounded theory as described above. 
 
8C. Evaluation of Safety Outcomes 
Demographic and disposition data, drug administration, medical history, prior and concomitant 
medications, adverse events (AEs), clinical laboratory measurements, vital signs, physical exam (PE) 
findings, and all other safety data will be listed by subject and time point. All subjects who receive any 
study medication (even if infusion is stopped prematurely) will be included in the safety analysis. All safety 
data, including AEs, serious adverse events (SAEs), vital sign data, PE findings, clinical laboratory test 
results, and concomitant medications, will be listed by subject. Adverse events will be summarized by 
method of collection type, frequency, severity, relationship to study drug, any change in study drug 
administration, and number of subjects per treatment. The severity of all AEs and all hematologic and 
biochemical toxicities will be rated according to a pre-specified rating system to be finalized at the first All-
Hands investigator meeting. Changes in PE and laboratory values that are expected will be excluded as 
AEs. For example, normocytic, normochromic anemia and peeling of the extremities are expected as the 
normal evolution of the disease process. However, hemolytic anemia (a potential risk for second IVIG arm) 
or upper respiratory tract infection (a potential risk for infliximab arm) would not be expected and would be 
classified as AEs. Frequency of treatment-emergent AEs and SAEs will be described by each treatment 
group and compared using Fisher Exact tests. These data will be included in monthly reports prepared for 
the study team and in the regular reporting to the DSMB. 
9. Data Safety Monitoring Board 
The clinical trial will utilize a DSMB to evaluate ongoing data from this randomized phase III trial. The 
board will be composed of a pediatric infectious disease specialist, a pharmacologist, a pediatric 
cardiologist and a biostatistician who are not investigators in this specific project and have no real or 
potential conflicts of interest with the clinical study.   
 
The DSMB will meet every six months (or more frequently, if desired by the committee) to review 
enrollment and safety data.  The proposed study will not have any planned interim analyses for efficacy or 
futility. The safety review will be prepared by the biostatistician, Dr. Sonia Jain.  An open review will 
include demographics and trial summary for the total population.  The committee, statistician, Project 
Manager, and the PI will attend the open portion.  During the closed review, the PI and other study 
personnel will not see the data reported by study arm. The committee will review safety data by arm.  A 
formal recommendation by the DSMB committee will be given to the PI, which will be reported to the 
participating sites, UCSD HRPP, and PCORI as appropriate.
