Amendment 6
29 September 2020
Amendments below are listed beginning with the most recent amendment.
Amendment 6 (29 September 2020)
The overall reason for the amendment: The overall reason for the amendment is to provide options for 
study-related participant management in the event of disruption to the conduct of the study due to the Coronavirus 
2019 (COVID-19) pandemic, remove alcohol breath test screening, extend the allowable time window for 
administration of the ADOS-2, change the version of the suicidality evaluation instrument used at screening, and 
modify the exclusion criterion regarding CYP3A4 inducers and inhibitors.
Applicable Section(s)
Description of Change(s)
Rationale:  Modifications to study conduct may be needed due to the COVID-19 pandemic.
9.1.1 Study Overview
Added reference to Attachment 16 for COVID-19 related guidance.
Attachments
Added Attachment 16 for guidance on study conduct during the COVID-19
pandemic.
Rationale: The risk of alcohol consumption on the day of a study visit is believed to be low in this patient 
population. Compliance with protocol-defined alcohol restrictions can be adequately assessed via verbal 
confirmation with subject and/or caregiver and general appraisal by site staff for signs of acute intoxication.
Time & Events;
9.1.2 Screening Phase
Removed alcohol breath test.
4.2. Exclusion Criteria
Removed positive tests for alcohol from Exclusion Criterion 9.
15.Materials
Removed breathalyzers.
Rationale: To broaden the allowable time window for ADOS-2 administration prior to the screening visit. ADOS-2 
scores are expected to be relatively stable within a 2-year period.
4.1 Inclusion Criteria;
9.2.2.6 Standard 
Instruments & Scales
Changed the allowable period for the ADOS-2 administration in Inclusion 
Criterion 2 from 12 months to 24 months prior to the screening visit.
Rationale: Removed requirement for investigators to consult with sponsor for all stable medical conditions given 
the burden and possible delay such a requirement poses and limited utility for well-managed, stable conditions. 
Investigators may continue to consult the sponsor should a subject’s concurrent medical diagnosis raise. 
4.2 Exclusion Criteria
Modified Exclusion Criterion 3 to indicate that the investigator, with consultation 
with the sponsor, if warranted, will determine whether patients with stable 
conditions can be enrolled in the study.

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
7
Status: Approved, Date: 29 September 2020
Applicable Section(s)
Description of Change(s)
Rationale: To more precisely define length of time for which moderate/strong CYP3A4 inhibitors or inducers are 
prohibited during the study, call attention to non-drug supplements to which the prohibition also applies, and clarify
that Attachment 2 comprises a non-exhaustive list of CYP3A4 inhibitors and inducers.
4.2 Exclusion Criteria
Modified Exclusion Criterion 5 regarding moderate/strong CYP3A4 inhibitors or 
inducers: 1) included supplements, 2) removed ambiguous language from the 
intended prohibited period and added additional language to account for CYP3A4 
inhibitors or inducers with unusually long half-lives by changing the period for 
restriction from one month to 30 days or 5 half-lives (whichever is longer) prior to 
Day 1, and 3) indicated that the Attachment 2 list of medications includes some 
examples of CYP3A4 inhibitors or inducers.
Rationale: A different version of the C-SSRS is needed at screening to capture suicidal ideation and behavior 
during the periods defined in the exclusion criterion. The current version only captures lifetime suicidality.
9.6.2 Suicidality Evaluation
Changed the version of the C-SSRS to be used at screening from the Baseline 
version to the Baseline/Screening version.
Attachments
Replaced representative pages of the C-SSRS used at screening in Attachment 12.
Rationale:
To clarify the description of qualified study site personnel. 
16.1 Design Considerations
Modified the description of qualified personnel to indicate that safety assessments 
will be performed by experienced and medically-qualified study site personnel.
Amendment 5 (13 April 2020)
The overall reason for the amendment: The overall reason for the amendment is to update the JNJ-42165279 
clinical background information, change the dosing regimen/dose, increase the sample size, and remove the cap on 
the number of adult patients to be enrolled.
Applicable Section(s)
Description of Change(s)
Rationale: Recent analyses of Phase 2 data with JNJ-42165279 indicate that AEA levels are not sufficiently 
sustained in all patients over a 24-hour dosing interval with 25 mg once daily dosing. Subjects with higher trough 
AEA levels showed superior efficacy than those with lower AEA levels in measures of depression and anxiety.
PK/PD modeling predicts that higher trough drug exposure and AEA levels can be achieved with twice daily (BID) 
administration of JNJ-42165279 25 mg (50 mg total daily dose) while maintaining good safety margins.
Time & Events
Changed the dosing regimen from once daily to twice daily, and changed “bottle” to 
“bottles.”
Time & Events;
6. Dosage;
9.1.3 Treatment Phase
Added that dosing in the clinic should be the subject’s first dose of the day.
Synopsis;
Time & Events;
6. Dosage;
9.4.1. PK Evaluations
Modified the description of which study drug administrations should have the date 
and time recorded. 
Synopsis;
3.1 Overview of Design
Described that subjects enrolled prior to Protocol Amendment 5 were randomized to 
receive once daily dosing of placebo or 25 mg JNJ-42165279 and all other subjects 
will receive twice daily (BID) dosing of placebo or 25 mg JNJ-42165279 (total daily 
dose of 50 mg).

Status: Approved, Date: 29 September 2020
Applicable Section(s)
Description of Change(s)
Synopsis;
2.1 Objectives;
9.1.3. Treatment Phase
Removed the reference to once daily dosing.
1.1. Background
Added information on the estimated drug exposure and safety margins of 
adolescents compared to adults, as well as the estimated impact of the change to BID 
dosing on Cmax and AUC in adults.
1.1 Background;
3.2.2.1 Rationale for 
including adolescents
Replaced the safety margins associated with once daily dosing of JNJ-42165279 25 
mg to those associated with 25 mg BID.
3.2.3. Rationale for Dose 
Modified the rationale for dose selection to reflect the change from once daily to 
BID dosing.
6. Dosage;
9.1.3. Treatment Phase
Indicated that treatment phase visits should be scheduled for mornings.
6. Dosage
Added information regarding dosing, including recommended and required dosing 
intervals for BID dosing.
Changed the definition of noncompliance to be recorded on diaries from >1 pill to 
>2 pills.
9.1.1. Overview
Removed information regarding the time of day for scheduled visits.
11.1. Subject Information
Changed the primary analysis set from Intent-to-Treat (ITT) to ITT-BID, which 
includes only subjects who are enrolled under BID dosing.
Synopsis;
11.2. Sample Size
Indicated that the sample size is based on the number of subjects to receive BID 
dosing. 
11.3. Efficacy Analyses
Deleted statement that all efficacy analyses will be based on the ITT analysis set.
11.3.1. Primary efficacy 
endpoints
Added that primary efficacy analysis will be based on the ITT-BID analysis set.
Added that additional sensitivity analyses for the primary efficacy endpoints may be 
specified in the SAP.
Removed the subgroups to be included in the descriptive statistics and indicated that 
this will be specified in the SAP. 
11.6. Safety Analysis
Added “by dose level” to the summaries of adverse events and clinical laboratory 
tests.
16.1. Study-Specific Design 
Considerations
Changed the dose from 25 mg to 25 mg BID (total daily dose of 50 mg). 
Rationale: As some subjects have been enrolled under once daily dosing prior to Protocol Amendment 5, the total 
sample size needs to be increased to have adequate power for the comparison of placebo BID and JNJ-42165279 25 
mg BID.
Synopsis;
3.1. Overview of Design
The number of subjects to be randomized in the study was changed from 60 to 80.
Rationale: Data are now available from one Phase 1 study in healthy Japanese subjects and two Phase 2 studies 
with JNJ-42165279.
Synopsis;
Introduction
Updated the brief description of Phase 1 and Phase 2 studies.

Added a summary of results of the Phase 1 study in healthy Japanese subjects (Study 
42165279EDI1007), the Phase 2 study in patients with severe social anxiety disorder 
(Study 42165279SAX2001), and the Phase 2 study in patients with major depressive 
disorder with anxiety symptoms (42165279MDD2001).
Rationale: The restriction to enroll no more than 50% adult subjects is being removed due to low adolescent 
enrollment to date. There is no expected impact on evaluation of treatment efficacy in this Proof-Of-Concept study.
Synopsis;
3.1 Overview of Design;
4.1. Inclusion Criteria;
5. Treatment Allocation
Removed statement that at least 50% of subjects will be adolescents.
Rationale: Recent analyses of Phase 2 data indicate that assessing the relationship between plasma AEA levels and 
efficacy measures can aid in the understanding of treatment efficacy.
Synopsis;
2.1.1. Objectives
Added a secondary objective to evaluate the relationship between plasma 
concentrations of 
and efficacy.
Synopsis;
3.2.5. Rationale for 
Biomarker Evaluations
11.4. Biomarker Analysis
Modified the description to state that 
levels will be correlated with efficacy and 
other clinical evaluations.
Rationale: The length of contraception usage by female subjects, as well as the period in which eggs (ova, oocytes) 
should not be donated, is intended to reflect the period of time JNJ-42165279 may exert an effect on female
reproductive cells. The time frame has been shortened to be consistent with the average menstrual cycle length. 
Additionally, clarification was needed on the length of contraception usage for female partners of male subjects.
4.1 Inclusion Criteria
Added the duration for use of contraception by female partners of male subjects
(mirroring the male subject’s duration of contraception use) to Criterion 4. 
Changed the duration of contraception use for female subjects in Criterion 19 from 
90 to 30 days after the last dose.
Changed the duration for female subjects to avoid donation of eggs in Criterion 20 
from 90 to 30 days after the last dose.
Rationale: To allow for revisions to the Evaluation of JAKE questionnaire during the study, the representative 
pages of this questionnaire were removed.

of a visit, and modified recommended limit to 2 drinks/day for males and 1 
drink/day for females.
Rationale: Eye-tracker calibration can be subject to environment factors in the equipment or room set up, rather 
than the intended purpose of evaluating subject characteristics. Thus, allowing calibration to be repeated to 
determine eligibility is considered appropriate.
Time & Events;
4.1 Inclusion (Criterion 14);
9.1.2 Screening
Indicated that the eye-tracker calibration can be repeated during the screening 
period to meet the criterion of “good” calibration.
Rationale: To assure that only individuals who spend some time every week with their parent/primary caregiver 
are enrolled in the study. The period of reporting for some study evaluations is over the past week. 
4.1 Inclusion
Inclusion Criterion #7: Changed the required period for individuals to spend with 
their parent/caregiver (if not living with them) to: “during each week they must 
either (A) spend at least 3 hours a day for at least 4 days or, (B) spend the 
weekend with a parent or primary caregiver.” 
Rationale: To change the QTc interval used for eligibility and reporting of abnormal intervals to be 
gender-specific, given the gender difference in QTc normal ranges. Additionally, to modify how changes in QTc 
intervals from baseline are summarized.
4.2 Exclusion Criteria
Modified the QTc interval in Exclusion Criterion #2 to indicate that QTcF 
>450 msec applies to males and added QTC interval >470 msec for females.

1 Introduction
Paragraph was revised to read:
The current study will be conducted to assess the efficacy, safety, tolerability, 
pharmacokinetics (PK), and pharmacodynamics (PD) of treatment with 
JNJ-42165279 using the Janssen Autism Knowledge Engine (JAKE®) system in 
adolescent and adult male subjects with ASD. This study is intended as the first 
cohort in a planned ‘Platform’ study of autism using the JAKE system and the 
Autism Behavior Inventory (ABI). Additional cohorts, using different 
investigational compounds may be added, either one at a time or even in parallel 
over the course of the study. Additional cohorts may be added through ‘Intervention 
Specific Appendices’ to the protocol. Information may be shared between cohorts 
particularly on placebo subjects enabling fewer placebo subjects in later cohorts. 
The study would thus not be considered completed until the final cohort completes. 
The results from the study will afford a more comprehensive understanding of ASD, 
and will support the development of JNJ-42165279 as a potential treatment for the 
core and/or associated symptoms of ASD.
Rationale: Secondary objectives and secondary endpoints were updated to include ABI-C and CGI-S rating scales 
for accuracy.
Synopsis; 2.1.1 Objectives
The following secondary objective was updated to include ABI-C and CGI-S:

Aberrant Behavior Checklist (ABC), Autism Behavior Inventory-Short Form 
(ABI-S), Autism Behavior Inventory-Clinician structured interview (ABI-C), 
Clinical Global Impression-Severity (CGI-S), Repetitive Behavior Scale-
Revised (RBS-R), Zarit Burden Interview (ZBI), Child Adolescent Symptom 
Inventory-Anxiety (CASI-Anx), and Social Responsiveness Scale 2 (SRS-2)


The change from baseline to Day 85 in the ABC, ABI-S, ABI-C, CGI-S, RBS-
R, ZBI, CASI-Anx, and SRS-2 scales.
Rationale: Study design section was revised to specify the collection of a PK blood sample from eligible subjects 
on Day 1, and conducting an interim PK analysis following randomization of at least 8 subjects (aged 13-17 years) 
on active drug.
Synopsis; 3.1 Overview of 
Study Design
In the Double-Blind Treatment Phase section, paragraph was revised to read:
A pharmacogenomic blood sample will be collected from all eligible subjects at the 
time point described in the Time and Events Schedule. Participation in the 
pharmacogenomic research component is requested for the identification of genetic 
factors that may influence PK, pharmacodynamics (PD), safety and/or tolerability of 
JNJ-42165279. 
Subjects (aged 13-17 years) will be randomized until at least 8 subjects are on the 
active drug, following which screening of subjects of that age range will be 
temporarily paused while an interim PK analysis is conducted.
Rationale: In the rationale for dose selection section, text pertaining to use of allometric scaling to predict 
concentration-time profiles of 25 mg q.d. doses in adolescent subjects was revised for accuracy.
3.2.3 Rationale for Dose 
Selection
Paragraph was updated to read:
Allometric scaling was applied to predict the concentration-time profiles produced 
by 25 mg q.d. doses in adolescent subjects (12-17 years). Based on these 
simulations, exposures (ie, plasma Cmax and AUC) up to 1.5 fold higher than in 
adults can be expected in subjects who are 12 years of age. Exposures up to 1.2 fold 
higher than in adults can be expected in subjects who are 15 years of age. Exposures 
in the 17 years age group are expected to be very similar to exposures observed in 
adults. Based on these results, no dose adjustments are recommended for adolescent 
subjects. Based on FDA age classification, enrollment will include subjects 13 years 
of age and older.
Rationale: A new section on the rationale for pharmacokinetic evaluations was added for clarity.
3.2.4 Rationale for 
Pharmacokinetic Evaluations
In the new section, the following text was added:
If warranted at the time of the interim analysis and after completion of the study, the 
plasma concentration-time data of JNJ-42165279 will be analyzed using population 
PK modeling. Concentration-time data will allow estimation of individual PK 
parameters for JNJ-42165279. It will also help to understand potential differences 
between ASD subjects treated with JNJ-42165279 and those treated with placebo. 
Time and days of JNJ-42165279 plasma concentration assessment were chosen to 
gather maximal information about the PK properties of JNJ-42165279 while 
minimizing subject burden regarding blood sampling.
Rationale: Descriptions of the components of the JAKE Portal were revised for accuracy.
3.2.5.1 JAKE Portal
Descriptions of the components of the JAKE Portal were revised.
Rationale: The tasks and stimuli for use with the Periodic Biosensors were clarified for accuracy.
3.2.5.2.2 Periodic Biosensors 
and JAKE Task Battery
Descriptions of tasks and stimuli for use with the Periodic Biosensors were 
clarified.

SYNOPSIS
A Randomized, Double-Blind, Placebo-Controlled, Parallel Group, Multicenter Study Investigating 
the Efficacy, Safety, and Tolerability of JNJ-42165279 in Adolescent and Adult Subjects with 
Autism Spectrum Disorder
JNJ-42165279 is a potent, selective, and orally bioavailable inhibitor of the enzyme fatty acid amide 
hydrolase (FAAH). This enzyme is primarily responsible for the degradation of a variety of fatty acid 
amides (FAAs), including the endocannabinoid N-arachidonoylethanolamine, or anandamide (AEA), the 
first identified endogenous cannabinoid receptor agonist. The endocannabinoid system is believed to play 
important roles in the regulation of the immune system, pain perception, affect, motivation, emotion, fear 
and anxiety responses. As such, the endocannabinoid system and FAAH inhibition could modulate the 
core symptoms associated with social communication deficits, and restrictive and repetitive behaviors
(RRB). Evidence has demonstrated that the endocannabinoid system is involved in behavior and emotion 
directly relevant to Autism Spectrum Disorder (ASD). Modulation of behavior and emotion related to 
ASD is the basis for testing JNJ-42165279 for therapeutic effect in adolescent and adult subjects with 
ASD.
JNJ-42165279 has been studied in 7 Phase 1 studies and 2 Phase 2a studies. The Phase 1 studies included
a single ascending dose regimen up to 250 mg and a multiple dose regimen of 100 mg once daily in 
healthy males, a study with healthy Japanese males administered a single dose and multiple dose regimen
of 25 mg once daily for 10 days, a multiple dose study with cohorts receiving 10, 25, 75 or 100 mg for 10 
days, a brain FAAH occupancy study using positron emission tomography (PET), a drug-drug interaction 
study (DDI), an oral bioavailability study, and a functional magnetic resonance imaging (fMRI) study 
with a dose of 100 mg once daily over 4 days to healthy males. Both Phase 2a studies evaluated the safety 
and efficacy of once daily dosing of JNJ-42165279 25 mg using a double-blind, randomized, 
placebo-controlled design. One of the Phase 2 studies included patients with severe social anxiety 
disorder, while the other evaluated patients with major depressive disorder with anxious distress.

OVERVIEW OF STUDY DESIGN
This is a randomized, multi-center, double-blind, placebo-controlled, parallel group, outpatient study 
assessing the efficacy, safety, and tolerability of JNJ-42165279 during 12 weeks of treatment in
adolescent and adult subjects with ASD. 
Approximately 80 adolescent and adult subjects (between 13 and 35 years of age, inclusive) will be
randomized in a 1:1 ratio to receive double-blind treatment of either JNJ-42165279 or placebo. The 
randomization will be stratified by gender and age (13-17 years and 18-35 years). Subjects enrolled prior 
to Protocol Amendment 5 were randomized to receive once daily dosing of placebo or 25 mg 
JNJ-42165279 throughout the treatment period. All other subjects will receive twice daily (BID) dosing 
of placebo or 25 mg JNJ-42165279 (total daily dose of 50 mg).
Study procedures include safety and efficacy evaluations and blood sample collections for 
pharmacogenomic assessment, pharmacokinetics, and biomarkers of treatment activity. An interim PK 
analysis is planned following Week 2 PK sample collection from approximately 8 adolescent subjects 
randomized to active drug. 
This study consists of a 26-day eligibility screening period, a 12-week double-blind treatment period and 
a follow up examination (to occur 14 days [±1 week] after last dose of study drug). The study duration for 
each subject will be approximately 4 months.
Screening (Day -26 to Day -1)
Subjects will be screened within 26 days prior to Day 1 of the double-blind period to assess their 
eligibility for the study, according to the inclusion and exclusion criteria. Caregivers will return for a 
second screening visit for set up and training for the caregiver reporting tool (My JAKE/My JAKE 
Mobile Medical App v 1.0 [My JAKE MMApp]), and for completion of select scales.
Double-Blind Treatment Phase
Subjects who successfully complete the screening phase will visit the clinical site/unit to be randomized
on Day 1 (Baseline visit) of the double-blind phase. 
Subjects will visit the study site with their caregiver at 2, 4, 8, and 12 weeks after the start of treatment. 
Throughout the treatment period, caregivers will record information in the caregiver reporting tool and 
subjects will wear a continuous biosensor wristband that measures activity.
Follow Up Phase
Subjects will return to the clinical site for a safety follow up visit at 14 days (±1 week) following the last 
dose of study drug (Day 85).
SUBJECT POPULATION
Subjects (13 to 35 years of age) with a definitive diagnosis of ASD using the Autism Diagnostic 
Observation Schedule, Second Edition (ADOS-2), who have an IQ as measured by the KBIT-2 of ≥60, 
and who are capable of completing and complying with all study-specific requirements will be enrolled.
DOSAGE AND ADMINISTRATION
Following Protocol Amendment 5, subjects will self-administer double-blind study medication twice 
daily for 12 weeks. Study medication will be provided as JNJ-42165279 25 mg tablets, or matching 
placebo, packaged in bottles. All tablets (JNJ-42165279 /placebo) are identical in appearance.

PHARMACOKINETIC EVALUATIONS
Venous blood samples for analysis of JNJ-42165279 in plasma will be collected at the time points 
indicated in the Time and Events Schedule.  
BIOMARKER EVALUATIONS
During the study, the following PD evaluations will be performed at the time points indicated in the Time 
and Events schedule: plasma concentrations of 
.
Additionally, blood biomarkers related to autism (including but not limited to cytokines and miRNAs) 
will be investigated to allow for exploratory immunophenotyping and for an exploratory PD evaluation. 
Biomarkers may be added or deleted based on scientific information or technical innovations under the 
condition that the total volume of blood collected will not be increased.
The biomarker data obtained from this study may also be included in an ongoing cross-study analysis to 
investigate the relationship between ASD and phenotypes and biomarkers.
PHARMACOGENOMIC (DNA) EVALUATIONS
A pharmacogenomic blood sample will be collected from all eligible subjects. Deoxyribonucleic acid 
(DNA) samples will be analyzed for FAAH gene variants. Additional analyses may be conducted if it is 
hypothesized that this may help resolve issues with the clinical data. DNA samples may also be used for 
the identification of genetic and/or epigenetic factors that may influence the PK, PD, efficacy, safety 
and/or tolerability of JNJ-42165279, and for exploratory genetic and/or epigenetic analyses, including of 
autism.
DNA samples will be used for research related to JNJ-42165279 or ASD. They may also be used to 
develop tests/assays related to JNJ-42165279 or ASD. Pharmacogenomic research may consist of the 
analysis of 1 or more candidate genes or of the analysis of genetic markers throughout the genome or 
analysis of the entire genome (as appropriate) in relation to JNJ-42165279 or ASD clinical endpoints.
The pharmacogenomics data obtained from this study may also be included in an ongoing cross-study 
analysis to investigate the relationship between ASD and phenotypes and biomarkers.

SAFETY EVALUATIONS
During the study, regular safety assessments will be performed as listed in the Time and Events Schedule. 
These safety assessments include but are not limited to: vital signs, electrocardiogram (ECG), physical 
examination, adverse events, Columbia Suicide Severity Rating Scale (C-SSRS), Aberrant Behavior 
Checklist-Irritability Subscale (ABC-I), and clinical laboratory tests.
STATISTICAL METHODS
Sample Size Determination
The sample size for the study is based on all subjects who are enrolled under BID dosing. The assumption 
used in the determination of sample size was a treatment effect size of 0.63 for the difference between the
JNJ-42165279 treatment group and placebo, calculated as the mean change in the primary endpoints from 
baseline to Day 85. To detect the treatment effect size of 0.63 in any of the primary endpoints with a 
power of 90% at an overall 1-sided significance level of 0.10, 25 subjects in each group are required.
When adjusted for a drop-out rate of approximately 15% of subjects, this will require 60 subjects (under 
BID dosing) to be randomly assigned to treatment in a 1:1 ratio (30 per group).
Efficacy Analysis
The primary efficacy analysis will be based on the ITT-BID analysis set. The primary efficacy endpoints
are the changes from baseline to Day 85 in the ABI Core Domain Score, ABI Social Communication 
Domain Score, and ABI RRB Domain Score during the double-blind treatment phase. Each will be 
analyzed using a mixed effects model for repeated measures (MMRM). The model will include time, 
treatment, time-by-treatment interaction, age group (13-17 years and 18-35 years, inclusive), and gender
(male and female) as factors, and baseline score as a continuous covariate. An unstructured variance-
covariance matrix will be used. In case of convergence problems, simpler variance-covariance structures 
such as Toeplitz or autoregressive order 1 (AR[1]) will be considered. The study will be deemed positive 
if any of the primary efficacy endpoints are statistically superior to placebo using a 1-sided 0.10 
significance level.
For the secondary efficacy endpoints, comparisons between JNJ-42165279 and placebo will be performed 
by means of an MMRM model as described for the primary efficacy endpoints. Relationships between
select biosensors and scales will be measured with the appropriate correlation analyses.
Biomarker and Pharmacogenomic Analysis
Baseline biomarker values (collected during screening) and changes from baseline to the time points
specified in the Time and Events Schedule will be assessed. Biomarker values will be tabulated by 
treatment group over time points and summary statistics will be calculated. Associations between 
biomarkers and clinical endpoints will be explored. Correlations between 
values with efficacy and 
other clinical evaluations will be assessed.
Pharmacogenomic analyses may include candidate gene analyses or genome-wide association analyses in 
relation to treatment response.
Pharmacokinetic and Pharmacokinetic/Pharmacodynamic Analysis
An interim analysis will be conducted to evaluate the concentrations of JNJ-42165279 in plasma of 
adolescent subjects. The analysis would be performed after approximately 16 adolescent subjects (ie, 8 
adolescent subjects randomized to active drug) have been randomized and participated in the PK
sampling at the Week 2 visit.
The individual plasma JNJ-42165279 concentration-time values will be listed and summarized 
descriptively.

plasma concentrations of 
 will be plotted to evaluate the relationships graphically.
Population PK/PD analysis of biomarkers and/or efficacy markers may also be performed, and a suitable 
dose- and/or exposure-response model may be developed. 
Safety Analysis
All randomized subjects who receive at least 1 dose of study medication will be included in the safety 
analysis set. Adverse events will be coded using the current version of Medical Dictionary for Regulatory 
Activities (MedDRA). All reported adverse events with onset during the double-blind treatment phase (ie, 
treatment-emergent adverse events [TEAEs], and adverse events that have worsened since baseline) will 
be included in the analysis. For each TEAE, the percentage of subjects who experience at least 
1 occurrence of the given event will be summarized by treatment group and dose level. Serious adverse 
events will be summarized separately.
Laboratory data will be summarized by type of laboratory test. Descriptive statistics will be calculated for 
each laboratory analyte at baseline, and for observed values and changes from baseline at each scheduled 
time point.
Descriptive statistics of pulse, blood pressure (systolic and diastolic), temperature, and body weight 
values and changes from baseline will be summarized at each scheduled time point.
Subjects with abnormal findings in ECG will be listed.
Suicide-related thoughts and behaviors based on the C-SSRS will be summarized by treatment group in 
incidence tables.
Irritability, aggression, and self-injurious behavior based on the ABC-I will be summarized descriptively

INTRODUCTION
There is a growing interest in developing novel medicines for the treatment of Autism Spectrum 
Disorder (ASD). The emerging evidence from genomics, neuroimaging, and neurobiologic 
research is elucidating new molecular targets with the potential for clinical benefit. Given the 
high incidence of ASD (1 in 68 births in the United States of America [USA]), the significant 
unmet medical need, and long-term associated morbidity, there are multiple facets of the disorder 
that could benefit from novel treatments. There are currently no medications approved for the 
treatment of core symptoms of ASD.
JNJ-42165279 is a potent, selective, and orally bioavailable inhibitor of the enzyme fatty acid 
amide hydrolase (FAAH). This enzyme is primarily responsible for the degradation of a variety 
of fatty acid amides (FAAs), including the endocannabinoid N-arachidonoylethanolamine, or 
anandamide (AEA), the first identified endogenous cannabinoid receptor agonist. The 
endocannabinoid system is believed to play important roles in the regulation of the immune 
system, pain perception, affect, motivation, emotion, fear and anxiety responses. As such, the
endocannabinoid system and FAAH inhibition could modulate the core symptoms associated 
with social communication deficits, and restrictive and repetitive behaviors (RRB). Evidence has 
demonstrated that the endocannabinoid system is involved in behavior and emotion directly 
relevant to Autism Spectrum Disorder (ASD).122 Modulation of behavior and emotion related to 
ASD is the basis for testing JNJ-42165279 for therapeutic effect in adolescent and adult subjects 
with ASD.
JNJ-42165279 has been studied in 7 Phase 1 studies and 2 Phase 2a studies. The Phase 1 studies 
included a single ascending dose regimen up to 250 mg and a multiple dose regimen of 100 mg 
once daily in healthy males, a study with healthy Japanese males administered a single dose and
multiple dose regimen of 25 mg once daily for 10 days, a multiple dose study with cohorts 
receiving 10, 25, 75 or 100 mg for 10 days, a brain FAAH occupancy study using positron 
emission tomography (PET), a drug-drug interaction study (DDI), an oral bioavailability study, 
and a functional magnetic resonance imaging (fMRI) study with a dose of 100 mg once daily 
over 4 days to healthy males. Both Phase 2a studies evaluated the safety and efficacy of once 
daily dosing of JNJ-42165279 25 mg using a double-blind, randomized, placebo-controlled 
design. One of the Phase 2 studies included patients with severe social anxiety disorder, while 
the other evaluated patients with major depressive disorder with anxious distress.
The participation, dosing, and enrollment in the Phase 2a studies was voluntarily suspended by 
Janssen on 16 January 2016 following the report of serious adverse events (SAEs) occurring in a 
Phase 1 clinical study conducted by Biotrial, Rennes, France while evaluating BIA 10-2474, a 
FAAH inhibitor from Bial Pharmaceutical company, Trofa, Portugal. Janssen received formal 
notification from the US FDA of the full clinical hold of 3 active Investigational New Drug 
Applications (INDs) related to JNJ-42165279, pending further investigation into the cause of the 
Bial trial’s serious adverse events. Investigations were completed by European and US health 
authorities and the hold placed by the FDA was removed on 22 September 2016.

Results from preclinical studies on ASD have determined that variation/mutation/disruption of 
the endocannabinoid system is associated with behavioral and electroencephalogram (EEG) 
changes.45,59,132 Specifically, the CB1 cannabinoid receptors and their endogenous ligands (AEA 
and 2-arachidonoyl-sn-glycerol [2-AG]) have been associated with modulating social play and 
social anxiety, 2 pivotal facets of social behavior.14,49,96,131 In a study that examined genes with 
abnormal expression levels in the cerebella of subjects with autism compared with control 
subjects, it was determined that the CB1 gene demonstrated a 30% down-regulation in subjects 
with autism.98 Furthermore, CB1 gene variations contributed to regulating the perception of 
signals of social reward, such as happy faces, suggesting that CB1 is a critical component in the 
molecular perception of social behavior.25 FAAH inhibitors and other endocannabinoid 
modulators reverse core ASD behaviors and comorbidities in preclinical models.59,132 For 
instance, a recent study in mice has demonstrated that AEA signaling at CB1 receptors modulates 
the incentive salience of social interactions, and this was independent of AEA’s ability to 
regulate anxiety.141 Oxytocin receptor activation by endogenous oxytocin enhances AEA 
mobilization in the mouse nucleus accumbens. This indicates that oxytocin functions as a social 
reinforcement signal within this limbic region. Furthermore, heightened AEA signaling (via 
FAAH inhibition) stimulates social reward and occludes the prosocial effects of oxytocin. These 
results suggest that pharmacologic modulation of oxytocin-driven AEA signaling via a FAAH 
inhibitor (such as JNJ-42165279) may be beneficial in the treatment of social impairment in 
ASD. Overall, these findings support the hypothesis that modulation of the endocannabinoid 
system by a FAAH inhibitor may improve the core symptoms of ASD.
The current study will be conducted to assess the efficacy, safety, tolerability, pharmacokinetics 
(PK), and pharmacodynamics (PD) of treatment with JNJ-42165279 using the Janssen Autism 
Knowledge Engine (JAKE®) system in adolescent and adult subjects with ASD. This study is 
intended as the first cohort in a planned ‘Platform’ study of autism using the JAKE system and 
the Autism Behavior Inventory (ABI). Additional cohorts, using different investigational 
compounds may be added to the Platform study, either one at a time or even in parallel over the 
course of the study. Additional cohorts may be added through ‘Intervention Specific 
Appendices’ to the Platform protocol. Information may be shared between cohorts, particularly 
data from placebo subjects, enabling fewer placebo subjects in later cohorts. The Platform study 
would thus not be considered completed until the final cohort completes. The results from the 
study will afford a more comprehensive understanding of ASD, and is intended to support the 
development of JNJ-42165279 as a potential treatment for the core and/or associated symptoms 
of ASD.

Background
For the most comprehensive nonclinical and clinical information regarding the efficacy and 
safety of JNJ-42165279, refer to the latest version of the Investigator’s Brochure (IB) for 
JNJ-42165279.

Pharmacokinetics and Product Metabolism in Animals
During pregnancy, rat and rabbit fetuses were well exposed to JNJ-42165279 and the drug 
distributed to the eyes of both species. In concert with the substantially higher (4-fold) plasma 
exposures in rabbit compared to rat dams, the rabbit fetus also had higher exposure (2 to 4 –fold 
comparing plasma and whole fetus exposure in rats and rabbits) to JNJ-42165279. In addition, 
the exposure in rabbit fetal eyes was 3-fold higher than that in rat fetal eyes. Comparing total 
radioactivity to JNJ-42165279 levels, it is evident that JNJ-42165279 was more extensively 
metabolized in rats than rabbits leading to a higher metabolite burden in the rat fetuses (fetal eye, 
plasma, and whole) than in rabbits despite the generally higher exposures in rabbits.
No information is currently available about any pharmacology of any metabolites of 
JNJ-42165279.
Toxicology
The oral toxicity of JNJ-42165279 was characterized in GLP 2-week and 3-month toxicity 
studies in rats and dogs. In the GLP 3-month studies, adverse effects on coagulation parameters 
(increased prothrombin time [PT] and activated partial thromboplastin time [aPTT]) and the 
reproductive organs (decreased sperm motility and abnormal sperm morphology) were observed
in male rats at all doses. In female rats, microscopic changes were observed in the kidney 
(mineralization and vacuolar degeneration) at 25 mg/kg, while there were no findings at the low 
dose of 5 mg/kg. Based on these findings, the no observed adverse effect level (NOAEL) could 
not be established in male rats and was 5 mg/kg in female rats. Relative to exposures at the 
intended clinical dose of 25 mg BID (Cmax= 273 ng/mL and AUC = 3886 ng.h/mL), Cmax and 
AUC exposures in the female rats provide 8-fold and 3-fold margins respectively. In dogs, doses 
of 5 and 15 mg/kg were well tolerated, while adverse effects at 10050 mg/kg were noted in the

liver and gall bladder (vacuolation with cellular degeneration or necrosis that correlated with 
mild increases in aspartate transaminase [AST], alanine aminotransferase [ALT], alkaline 
phosphatase [ALP], and gamma-glutamyltransferase [GGT]), thymus (atrophy), bone 
(hypercellularity of the erythroid cell line in sternal bone marrow), and epididymis/testis 
(decreased sperm numbers and secondary spermatid degeneration/depletion). Based on these 
findings, the NOAEL in dogs was 15 mg/kg, providing Cmax and AUC margins of at least 21-fold 
and 20-fold over those at the anticipated human exposures.
Reproductive and embryo-fetal safety was evaluated in rats and rabbits. Male rats treated with 
JNJ-42165279 for 4 weeks had significantly reduced sperm motility and increased number of 
abnormal sperm at doses of 100 and 200 mg/kg but not at 25 mg/kg; these changes were fully 
reversible following a 4-week recovery period and are considered exaggerated effects of FAAH 
inhibition. JNJ-42165279 at the high dose of 100 mg/kg, but not at ≤30 mg/kg, induced changes 
in female rat oestrus cycling (regularity and cycle length), which is also likely an exaggerated 
effect of FAAH inhibition. The Cmax (3,280 ng/mL) and AUC (9280 ng.h/mL) exposures in male 
rats at 25 mg/kg (the NOAEL for fertility findings) provide margins of 12- and 2.4-fold over the 
anticipated human effective levels. In pregnant rats and rabbits, JNJ-42165279 induced minimal 
maternal toxicity in both species (decreased food consumption and body weight gain). There 
were no fetal changes in rabbits. In rabbits, the NOAEL for fetal toxicity was the highest dose 
tested, offering Cmax and AUC margins of over 64-fold. Rat fetuses at the high dose of 
100 mg/kg showed a significant increase in incidence of background primary lens fiber swelling 
and degeneration with or without fragmentation on histological evaluation. When offspring of 
pregnant rats dosed with JNJ-42165279 were allowed to grow to maturity, ophthalmoscopy 
revealed a significant increase in the incidence of nuclear cataracts at the high dose of 100 mg/kg 
with a slight trend at 30 mg/kg. Primary lens fiber swelling, focal degeneration and nuclear 
cataracts are common background findings in rats, but these were exacerbated by treatment with 
JNJ-42165279. Following an integrated assessment of the lens findings in 3 rat studies, the 
NOAEL for fetal toxicity was 10 mg/kg. At this dose, Cmax and AUC exposures (3,660 ng/mL 
and 19,200 ng.h/mL) provide 13-fold and 5-fold margins over anticipated mean human 
exposures at the dose of 25 mg BID. Adjusting for plasma protein binding (6.4% free in humans 
vs 9.1% free in rats), the Cmax and AUC margins are 19- and 7-fold, respectively. No treatment 
related changes were noted in adult eyes exposed to JNJ-42165279 for up to 3 months.
JNJ-42165279 was not genotoxic in the in vitro bacterial/microsomal activation assay, the mouse 
lymphoma assay, or the in vivo chromosome aberration test in rats.
Clinical Studies
JNJ-42165279
This will be the tenth study (7 Phase 1 studies completed, 2 Phase 2a studies completed, and this 
study) involving the administration of JNJ-42165279 to humans.
A double-blind Phase 1 study (Study 42165279EDI1001) was completed with 29 healthy male 
subjects to evaluate the safety, tolerability, PK, and PD activity of JNJ-42165279 after single and 
repeated oral dosing. In Part 1, 2 cohorts (both n=9) received single ascending doses of

coagulation parameters. There were no deaths, SAEs, or discontinuations due to adverse events. 
Subjects receiving 100 mg reported slight similarity to sedatives and dissimilarity to stimulants 
on the Addiction Research Center Inventory-53; no groups reported similarity to cannabinoids. 
No subjective effects were reported in any of the cohorts by Bond-Lader visual analogue scales.  
During the DDI study 42165279EDI1004 16 subjects received a single 30 mg JNJ-42165279 
dose on Day 1. Thereafter, they received single oral doses of 200 mg itraconazole from Day 4 to 
Day 10 (inclusive). Subjects also received a dose of 30 mg JNJ-42165279 along with 200 mg 
itraconazole on Day 8.
In the safety analysis, the most frequently reported TEAEs (n=2) were
dry throat 
(JNJ-42165279), rhinitis (itraconazole), and erythema (JNJ-42165279 and itraconazole). All 
other TEAEs were reported as a single incident. All the TEAEs were mild in intensity except for 
2 TEAEs (dry throat after JNJ-42165279, and bone contusion after JNJ-42165279 and
itraconazole treatments) which were moderate in intensity. None of the TEAEs were reported as 
severe and all of the TEAEs resolved at the end of the study. None of the TEAEs were probably
or very likely related to the study drug. Two subjects had TEAEs of elevated ALT. However, 
both events were mild in intensity and were considered possibly related to itraconazole by the 
investigator.
An analysis of brain FAAH occupancy by JNJ-42165279 using PET of 11C-MK-3168 has been 
conducted (study 42165279EDI1003). 
 
 
 
 
 
From the analysis of safety data, it was determined that all TEAEs reported in the study 
were mild in severity and all TEAEs were considered to be not related to the study agent, except 
for the event of headache, which was reported as possibly related to the study agent.

Study 42165279ANX1001 examined whether JNJ-42165279 (100 mg administered once daily
over 4 days) affected blood oxygen level dependent (BOLD) fMRI signals in the amygdala
elicited by an Emotional Face Processing Task, in healthy young male subjects. In the safety 
analysis, no deaths or other SAEs were reported. A total of 14 (63.6%) subjects in the 
JNJ-42165279 group and 9 (42.9%) subjects in the placebo group reported at least 1 TEAE. The 
most frequently reported TEAE in the JNJ-42165279 group was headache (reported in 4 subjects 
[18.2%]), followed by fatigue, nasal congestion, and nasopharyngitis (each reported in 2 subjects 
[9.1%]). The most frequently reported TEAEs in the placebo group were headache, fatigue, 
dizziness, nausea (each reported in 2 subjects [9.5%]). All TEAEs were mild in severity, with the 
exception of 1 moderate TEAE (blood creatine phosphokinase increased, in a subject assigned to 
placebo). Most TEAEs were considered to be unrelated or of doubtful relationship to study agent 
by the investigator. Five subjects in the JNJ-42165279 group and 5 subjects in the placebo group 
had a TEAE that was considered possibly or probably related to study agent by the investigator; 
no subject had a TEAE that was considered by the investigator to be very likely related to study 
agent. TEAEs considered possibly or probably related were headache, dizziness, fatigue, nausea, 
palpitations, migraine, energy increased, nasal congestion, and insomnia. All TEAEs had 
resolved by the end of the study. No suicidal ideation or suicidal behavior was reported based on 
the results of the Columbia Suicide Severity Rating Scale (C-SSRS). No clinically relevant 
changes in mean vital sign parameters and mean laboratory parameters were observed in the 
JNJ-42165279 or placebo group. There were no clinically relevant changes observed in liver

function tests. In light of the reports from the Biotrial study, T1 weighted scans obtained during 
the Day 4 MRI session were evaluated by an independent neuroradiologist, and no findings of 
concern were noted.
The clinical effects of JNJ-42165279 in patients with severe social anxiety disorder were
investigated in a double-blind, parallel-group, Phase 2a study (42165279SAX2001). A total of 
149 patients were randomized to receive once daily treatment with either JNJ-42165279 25 mg 
or placebo for 12 weeks. The treatment groups did not significantly differ in improvement in the 
Liebowitz Social Anxiety Scale (LSAS) total score (primary endpoint), nor in other measures of 
anxiety and depression. The percentage of subjects with ≥30% improvement on the LSAS total 
score was significantly higher in subjects treated with JNJ-42165279. Additionally, the 
percentage of subjects much improved or very much improved on the CGI was also significantly 
higher in subjects treated with JNJ-42165279. The occurrence of TEAEs was similar across the 
2 treatment groups (62.2% JNJ-42165279 versus 56% placebo). The most frequent TEAEs in 
subjects treated with JNJ-42165279 were headache, fatigue, upper respiratory infection, diarrhea, 
and nasopharyngitis. There were 2 SAEs reported in the JNJ-42165279 treatment group: 
anaphylaxis due to accidental egg ingestion in a subject with known allergy, considered 
unrelated to study drug, and alcohol use disorder considered doubtfully related to study drug. 
There were no SAEs reported in the placebo group.  
Another Phase 2a study, 42165279MDD2001, investigated the effects of JNJ-42165279 in 
patients diagnosed with major depressive disorder with anxiety symptoms who were not 
receiving adequate control with their SSRI/SNRI treatment. In this randomized, double-blind, 
parallel-group study, patients received once daily treatment with JNJ-42165279 25 mg or 
placebo for 6 weeks after a placebo lead-in period. There were no significant treatment 
differences in the primary endpoint, the Hamilton Depression Rating Scale (HDRS17), or in other 
efficacy measures. The proportion of patients experiencing TEAEs was 23.4% in the 
JNJ-42165279 group and 36.8% in the placebo group. TEAEs occurring in 2 or more subjects 
treated with JNJ-42165279 were headache and nasopharyngitis (3 subjects each), and 
neutropenia (2 subjects). There were 2 SAEs experienced by subjects in the JNJ-42165279 
treatment arm: a bunion resulting in elective/corrective surgery and an anaphylactic reaction due 
to accidental shrimp ingestion by a subject with known shellfish allergy, which occurred 14 days 
into the withdrawal period. One placebo subject experienced an SAE of gastroenteritis during the 
treatment period. See Section 3.2.3 for information on PK/PD analyses performed for this study.

JAKE System
A series of studies have been conducted leading up to the present study to test and assess various 
components of the overall JAKE System.
MENTIS-HV-001
The primary objective of this study was to assess the functionality of preliminary, testable 
components of JAKE, for use as a digital health data capture system in adult subjects without 

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6

autism. The secondary objective was to assess the feasibility of deployment and in-home use of 
JAKE for up to 24 weeks. This included an examination of use patterns of preliminary, testable 
JAKE components. The exploratory objective was to explore the relationship between biosensor 
data and self-reported information on health, mood, and activity.
The JAKE preliminary, testable components included in the study were the following: 
1.
A pre-production-environment (PPE) version of Microsoft HealthVault  
2.
The web-based JAKE User Interface (UI)
3.
The JAKE smart phone application (App) that prompted participants for information about 
mood, sleep, and activity throughout the day (available on Android and iOS devices)
4.
FitBit®Flex™, a wrist band biosensor that measures activity and sleep 
5.
Affectiva Q™, a wrist band biosensor that measures skin conductance
6.
FitBit®Aria™ WiFi Scale to measure body weight
7.
A confidential, private database where information collected through JAKE and biosensors 
was stored
8.
Cerora MindReader™, a portable, single-lead wireless EEG
device (OPTIONAL 
COMPONENT).
A total of 25 subjects (17 males, 8 females) were screened and enrolled in the trial. Of those, 
21 subjects completed the trial. 
In general, the results of the System Usability Scale suggested that subjects had a favorable view 
of the system. Scores on individual items generally improved between Visit 2 and Visit 3, as 
subjects gained more experience with the system. Examples of items that were more favorably 
rated included: “I think I would like to use this website frequently” (median=agree), “I thought 
the website was easy to use” (median=agree), and “I found the various functions in this website 
were well integrated” (median=agree). Less favorably rated included: “learning how to use it 
required a little / no time” (median=agree somewhat), “after using it for a while you can’t 
imagine not having it” (median=neither agree nor disagree), and “makes me feel in control when 
managing various aspects of Autism” (median=neither agree nor disagree). Some of the less 
favorable items, however, were more oriented towards a clinical population ie, ASD, rather than 
a healthy volunteer population, and this may have affected subjects’ ability to respond 
appropriately. 
Several system problems and software bugs were identified, including scaling problems with 
items on the phone application, registration difficulties and problems with initial application 
downloads, and difficulties with visualization of data from symptom ratings. These were fixed 
during the course of the trial, and retested with a successful outcome. 
Subjects entered a large amount of presumed fictitious medical history information, ranging from 
vital signs (blood pressure example provided below), to family history, to medical conditions and 
medications. As an example, 17 subjects provided hypothetical blood pressure ratings (not from 
actual sphygmomanometer measurements), with a total of 35 observations. This demonstrates 

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
57
Status: Approved, Date: 29 September 2020
the feasibility of transferring dynamic measures of vital signs from HealthVault (in this case, a 
fictitious PPE account) into the research data warehouse. In the future, these data could be 
generated from automated devices, from medical records obtained directly from physicians’ 
offices, or self-entered data.
Subjects were also able to successfully utilize the Affectiva Q sensor band, and data from this 
band were uploaded for further analysis showing readings of activity/movement, sleep (in some 
cases), and galvanic skin response within expected levels for healthy adults. A large proportion 
of subjects were able to complete the voluntary EEG portion of the study, and a total of n=11 
participants completed at-home administration of the EEG battery. Data demonstrated that it is 
feasible to conduct home-based self-administration of EEG and computer-based tasks. This was 
true across the various tasks included in the approximately 20-minute EEG battery. Several data 
discrepancies were noted which suggest that careful instruction and training may still result in 
minor inaccuracies that could have an impact on data quality, particularly in a clinical population 
(ie, individuals with ASD, with tests administered by a parent). 
Of the 21 subjects who completed, a total of 3 subjects reported adverse events. All 3 adverse 
events were related to the Affectiva Q sensor: all events were skin irritation and itching (2 mild, 
1 moderate severity). 
Results of this study confirmed the feasibility of utilizing a web-and-mobile system, as well as 
home and lab-based biosensors, for use in clinical trials. Important information was gleaned 
about the registration process, other procedures including connection and synchronization of 
devices, system bugs, and on the form factor of the MLE. The system itself was deemed to be 
easy to use once registration and linking of devices was complete. Further, connection of the 
MLE to, and biosensor data transfer into, Microsoft HealthVault was successful, as was data 
extraction from the HealthVault PPE to the Janssen Research Data Warehouse. Feedback 
provided on the MLE resulted in identification of pain points, as well as myriad constructive 
suggestions for how to improve the system.
Overall, the frequency and severity of adverse device effects was limited, resolved without 
intervention, and did not result in any long-term consequences to subjects.
MENTIS-AUT-0001
This Investigator Initiated pilot research study helped to evaluate how well-established JAKE 
System features would work in an applied setting, as well as informed future directions for JAKE 
System development.
This study utilized the Affectiva Q sensor device and a prototype web interface and personal 
health record platform developed by ilumivu, Inc. (the ilumivu Platform).
The following specific aims guided the pilot study:

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
58
Status: Approved, Date: 29 September 2020
1. Evaluate the usability and feasibility of stakeholders (ie, healthcare professionals) using the 
ilumivu Platform to collect behavioral and physiological data from individuals with ASD 
multiple times per day over several days.
2. Learn what elements of the ilumivu Platform will make multimodal data collection easy, 
useful, and compelling for stakeholders to use.
3. Assess the functionality of specific components of the ilumivu Platform, including:
A. Symptom ratings (both routine and momentary);
B. Biosensor data collection;
C. Stakeholder journaling;
D. Charting/visually displaying obtained information; and
E. Communicating between parents, school staff, and researchers.
From February 1, 2014 through April 25, 2014 (82 days), 91 Center for Discovery (CfD) staff 
members and parents used the ilumivu Platform to record information about 20 children in their 
care.
The trial successfully accomplished its goal by providing the research team with a clear 
understanding of what the JAKE System will be required to do in order to be clinically useful in 
a real-world setting. Responses from participants were critical in helping to determine clinical 
use and research needs while shaping the system into an effective tool for these particular 
stakeholder groups. Many new features and ideas were gained from talking to the staff and 
parents who used the system. A rich multi-user dataset was created to help inform both the 
Center for Discovery's clinical practice and their staff management policies.
MENTIS-HV-002
This study, conducted across 3 laboratories at Northeastern University, aimed to compare the 
usability, sensitivity, and accuracy of various experimental biosensors to that of their 
gold-standard, laboratory instrumentation counterparts. Feedback from this study informed
decisions on future development of the JAKE Biosensor Array.
The study was conducted in healthy, adult subjects and utilized tasks and stimuli to test the 
full-range of sensing capabilities of the various sensors in a single session.
The sensors modalities tested were actigraphy, galvanic skin response (GSR), ECG, EEG, and 
eye tracking.
Ten subjects were tested with EEG, 10 with eye tracking and 20 with actigraphy, GSR and ECG.
The study demonstrated that mid-range actigraph, eye tracking and EEG equipment were
logistically feasible to use and provided data quality sufficient for the intended analyses in future 
studies.
The mid-range ECG device was superior to the lab instrumentation.

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
59
Status: Approved, Date: 29 September 2020
The GSR devices tested were not comparable to the lab instrumentation, likely due to the lack of 
wet electrodes and to the placement on the wrist rather than the palm or fingertips. It is 
questionable whether these devices would provide adequate data.
MENTIS-ASD-001
MENTIS-ASD-001 was the first study conducted in subjects with ASD utilizing the complete 
JAKE System. Thirty-five subjects were enrolled; with approximately 15 of those undergoing 
the JAKE Task Battery and the remainder using only the JAKE Portal. Subjects in Stage 1 
participated for 1 week, while those in Stage 2 participated for 4 weeks. This study began the 
process of validating and optimizing the JAKE System, enabling the sponsor to optimize 
platform components such as the JAKE Task Battery, JAKE Biosensor Array, and JAKE Portal 
(including its subcomponents, such as the JAKE Symptom Tracker, later renamed ABI). 
Based on scale correlations for the ABI, it was determined that most correlations were 
statistically significant (p<0.001). Also, most of the standard scale correlation values between the 
baseline and endpoint visit were statistically significant (p<0.001). Most of the estimated 
correlations for the scales between the baseline and endpoint were >0.7. Correlations between 
the total ABI and domains of the ABI with the standard scale total and domain scores with which 
they might be expected to correlate were generally high (>0.7) and statistically significant 
(p<0.001).
The overall correlations between the key biosensor features with some standard scales such as 
SRS Social Communication and Child Adolescent Symptom Inventory-Total Score and 
Symptom Tracker, measured using Pearson’s correlations were strongly positive (r= ≥0.70) and 
considered significant (p<0.001) for ASD subjects. However, due to limited data available and 
small sample size during each stage, no definitive conclusions could be reached.
The experiences in this study led to many improvements, both in the biosensor devices used, the 
JAKE Portal software and processes, the Task Battery, and the Janssen Research Data 
Warehouse. As a whole, the System appeared to be a viable platform to be used in clinical 
studies of ASD. There were no safety issues observed with any components of the overall 
system. 
MENTIS-ASD-002
This was a non-interventional study that aimed to continue from MENTIS-ASD-001, and tested
and validated the final JAKE System. The testing and validation of the final JAKE System
included the subcomponents of the JAKE Portal (later renamed My JAKE), as well as the 
selected biosensors and procedures for biosensor testing that will be used for objective 
measurement of core and associated symptoms of ASD in a population of children, adolescents, 
and adults. The study also examined the JAKE Task Battery and selected components of the 
JAKE Biosensor Array (later renamed JAKE Sense) on a cohort of typically-developing (TD) 
children and adults in order to obtain comparative data. Feedback on both the My JAKE
interface and JAKE Sense biosensors were obtained, and data obtained via the interface and 
biosensors were compared to symptom measures commonly used in clinical research.

Status: Approved, Date: 29 September 2020
The study consisted of children and adults with ASD and a TD group for comparison. A total of 
185 participants (ASD, 144; TD, 41) were enrolled in this observational study. The majority of 
participants were male (ASD, 77.8%; TD, 65.9%); the mean (SD) age of participants was 
14.6 (7.83) years (ASD group) and 16.3 (13.18) (TD group). The ASD group participated in the 
JAKE Task Battery 3 times at approximately 4-week intervals. TD participants had a single visit 
wherein they underwent a single session with the JAKE Task Battery and biosensors.
The results demonstrated support for the utility of the ABI in measuring the clinical symptoms of 
ASD. The results supported the usability of the JAKE System (including subcomponents of 
My JAKE and selected JAKE Sense biosensors) for monitoring clinical outcomes in ASD. Key 
sensor variables of Periodic and Continuous Biosensors were identified using data mining 
approaches. Examination of sensor variables as change measures in the full dataset was
performed.
At the end of this study the sponsor validated the ABI, completed computer system validation on 
My JAKE and all of its subcomponents, developed the algorithms to extract meaningful features 
from My JAKE and JAKE Sense input, and identified the combination of biosensors and 
task/stimuli most likely to be able to detect changes in response to treatment.

3.2.1.
Randomization, Blinding, and Control
Randomization will be used to minimize bias in the assignment of subjects to treatment groups, 
to increase the likelihood that known and unknown subject attributes (eg, demographic and 
baseline characteristics) are evenly balanced across treatment groups, and to enhance the validity 
of statistical comparisons across treatment groups. Stratified randomization will be used for
gender (male and female) and age (13-17 years and 18-35 years). Blinded treatment will be used 
to reduce potential bias during data collection and evaluation of clinical endpoints as well as 
adverse events. A placebo control will be used to establish the frequency and magnitude of 
changes in clinical endpoints that may occur in the absence of active treatment.
3.2.2.
Study Population 
ASD is a neurodevelopmental disorder consisting of the core symptoms of social communication 
deficits and RRB. Associated symptoms include deficits in self-regulation, irritability, anxiety, 
depression, problems with attention, and challenging behaviors such as aggression. These criteria 
are laid out in the Diagnostic and Statistical Manual of Mental Disorders - 5th Edition (DSM-5)
and are widely accepted in the field.
The overall goal of subject selection is to identify subjects, aged 13 to 35 years old (inclusive),
with a definitive diagnosis of ASD using the Autism Diagnostic Observation Schedule, Second 
Edition (ADOS-2), who have an IQ as measured by the KBIT-2 of ≥60, and are capable of 
completing and complying with all study-specific requirements.
Given observations in the rat reproductive toxicology studies (see Section 1.1), women of 
childbearing potential (WOCBP) will only be included if they agree to ongoing use of a highly 
effective method of contraception (i.e. one that results in a less than 1% per year failure rate 
when used consistently and correctly). Pregnancy testing will be done at screening and at each 
study visit during the treatment phase. Safety and efficacy data in this population are important 
for future clinical studies.
3.2.2.1.
Rationale for Including Adolescent Subjects, Aged 13 to 17 Years
JNJ-42165279 has been evaluated for general toxicity in rat and dog studies of up to 3 months in 
duration. Evaluation of embryo-fetal toxicity has been completed in rats and rabbits, while 
fertility performance has been assessed in rats. Cardiovascular safety was evaluated in dogs and 
acute neurobehavioral effects assessed in rats. Animals used in the multiple dose toxicology 
studies straddled early to late reproductive maturity at study start. Specifically, animals used in 

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
65
Status: Approved, Date: 29 September 2020
the rat 2-week and 3-month studies were at least 8 weeks old, and therefore considered at the top 
end of adolescence, while those used in the neurobehavioral study were 6 weeks old (at start of 
adolescence). In dog studies, those for the 2-week study were 7 months old (adolescents), while 
those in the 3-month study were 10 months old at start of dosing (considered young adults). 
Several target organs were identified, mostly in the 3 month and reproductive safety studies. 
These included changes in kidneys of female rats only, coagulopathy in male rats only, liver 
changes in dogs only, testicular changes in both rats and dogs, and lens fiber swelling and 
fragmentation in fetuses of pregnant rats treated with JNJ-42165279 during the period of 
organogenesis.  
A key consideration in assessing the potential risk to human adolescents in a clinical trial is 
whether the target organs identified in the general and reproductive toxicity studies continue to 
undergo significant growth and development, which may not have been evaluated in young adult 
or adult animals used in the toxicity studies. In general, most human organs are fully developed 
by the age of 13 years with the notable exception of the brain cortex, the reproductive and 
skeletal systems. The endocannabinoid system is integral to brain development and reproductive 
function but has not been linked with skeletal development.
Reproductive function: Endocannabinoids are known to control multiple reproductive functions 
in both males and females through precisely orchestrated steps and levels requiring either up- or 
down regulation of various endocannabinoids particularly anandamide. Changes in anandamide 
levels play an integral role in sperm viability, acquisition of motility, and capacitation ability, 
amongst others.11,66,126 FAAH inhibition has also been demonstrated in preclinical models to 
modulate male fertility in a manner similar to exogenous CB1 agonists such
as 
tetrahydrocannabinol (THC).65,66,126 Mating wild-type female mice with FAAH knockout male 
mice had only a minimal effect on litter size while the effect was more significant when FAAH -/-
males were mated with FAAH -/- females. Sperm motility was also reported to be reduced in 
FAAH -/- males and this correlated with increased anandamide levels. In a study looking at 
endocannabinoid levels in sperm from fertile and infertile men, Lewis et al (2012) reported a 
substantial modulation of AEA metabolism in infertile men.66 Anandamide biosynthesis 
(3-fold lower) and to a lesser extent FAAH activity (2-fold lower) were significantly impaired in 
infertile versus fertile sperm plasma. In a case reference study by Pacey et al (2014), recent 
cannabis use emerged as a modifiable risk factor for <4% normal sperm morphology (criterion
for significant infertility).91 Although FAAH inhibition is expected to represent a selective 
stimulation of the CB1 receptors in specific regions as opposed to the broad and nonselective 
effects of exogenous CB1 agonists such as THC, the testicular effects in JNJ-42165729-treated 
rats and dogs appear to mirror those of THC administration. Therefore, in the absence of human 
data from FAAH inhibitors, it is reasonable to consider data on reproductive effects of cannabis 
use as the maximal possible pharmacological expression of FAAH inhibition. Treatment with 
JNJ-42165279 resulting in increased levels of anandamide is therefore expected to modulate 
sperm motility and possibly fertility. However, these effects were shown in the studies in rats 
and dogs to be dose dependent and reversible on treatment cessation as they are limited to 
spermatids, the last phase in spermatogenesis. In the GLP 3-month study in dogs, testicular 
effects were not seen at NOAEL AUC exposures 26-fold over the anticipated clinical AUC 

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
66
Status: Approved, Date: 29 September 2020
exposure. In the GLP rat 3-month study, sperm motility was reduced by 25%, and 39% of the 
spermatozoa were abnormal at the lowest dose tested (2.4-fold exposure ratio over the human 
exposures) but this level of change was shown to have no impact on pregnancy rates in the rat 
fertility study. In conclusion, FAAH inhibition through dosing with JNJ-42165279 has the 
potential to modulate sperm and fertility parameters in adolescents and adults but these effects at 
the clinical dose are expected to be minimal and reversible based upon preclinical studies and the 
known effects of CB1 agonists in humans.
Based on these observations, male subjects must use a condom and spermicide during the study 
and for a minimum of 1 spermatogenesis cycle after the last dose of study drug.
Neurobehavioral effects: There is limited literature data on the effects of FAAH inhibition on 
the developing brain and behavior. In the 3-month studies in rats and dogs, central nervous 
system-related clinical signs were mostly seen in dogs and limited to the high dose group. They 
included ataxia, excessive licking, salivation, tremors, and uncoordinated movement. In the 
Modified Irwin assay in rats, behavioral changes were limited to reduced muscle tone and 
reduced body temperature, well-recognized cannabimimetic effects. FAAH inhibition represents 
tonic activation of the endocannabinoid system. Although there is a growing body of evidence 
suggesting that chronic use of exogenous CB1 agonists such as cannabis (as distinct from FAAH 
inhibition) during adolescence could have deleterious neurocognitive effects, preclinical and 
clinical data have not reported any neurocognitive effects with JNJ-42165279. There is also 
evidence that CB1 activation including via heightened AEA signaling as a result of FAAH 
inhibition may be beneficial in the treatment of social impairment in ASD. Moreover, subjects 
with ASD have been shown to have altered expression levels of the CB1 gene, suggesting that 
intervention outcomes with FAAH inhibition could be different relative to normal subjects 
exposed to cannabis.
3.2.3.
Rationale for Dose Selection
Based on preclinical models of JNJ-42165279 efficacy with adjustment for differences in affinity 
of JNJ-42165279 for human FAAH, a 25 mg once daily regimen was chosen as the dose to carry 
forward into the Phase 2 proof of concept studies.
 
 
However, a post-hoc analysis of the Phase 2 studies 
42165279SAX2001 and 42165279MDD2001 found that the AEA concentrations observed in the 
JNJ-42165279 treatment group were only about 3-fold greater than the pre-drug concentrations.
AEA trough concentrations in these 2 studies exhibited a high degree of variability, and the
distribution of AEA trough concentrations in the JNJ-42165279 treatment group was found to 
overlap with that in the placebo group. These findings suggest that elevated AEA levels and 
FAAH inhibition associated with 25 mg JNJ-42165279 administered once daily was not 
sufficiently sustained for all subjects throughout the 24-hour dosage interval. 
The relationship between AEA trough concentrations and clinical outcomes was explored using 
the data from these Phase 2 studies. In the MDD2001 study, subjects with higher trough AEA 
concentrations after 6 weeks of treatment exhibited greater reductions in anxiety (measured by

the Hamilton Anxiety Rating Scale) and depression (measured by the HDRS17) than subjects 
with lower trough AEA levels.
 
 
 
See Section 1.1, Background, for information on safety margins. 
In view of these analyses
 
 
 the dose in the 42165279AUT2001 study will be changed to 
25 mg BID (50 mg total daily dose).

of the strong CYP3A4 inhibitor itraconazole, 
 
 respectively (Study 42165279EDI1004). CYP3A4 inhibitors will be restricted 
in this study. 
3.2.4.
Rationale for Pharmacokinetic Evaluations
If warranted at the time of the interim analysis and after completion of the study, the plasma 
concentration-time data of JNJ-42165279 will be analyzed using population PK modeling. 
Concentration-time data will allow estimation of individual PK parameters for JNJ-42165279. It 
will also help to understand potential differences between ASD subjects treated with 
JNJ-42165279 and those treated with placebo. Time and days of JNJ-42165279 plasma 
concentration assessment were chosen to gather maximal information about the PK properties of 
JNJ-42165279 while minimizing subject burden regarding blood sampling.
3.2.5.
Rationale for Pharmacogenomic and Biomarker Evaluations
A blood sample will be collected from all eligible subjects. Participation in the genomics 
research component is required to assess whether the subject is carrier of the A-allele variant for 
FAAH and to identify genetic factors that may influence the PK, PD, efficacy, safety and/or 
tolerability of JNJ-42165279.
Plasma concentrations of 
 will be used as biomarkers of JNJ-42165279 activity. 
Correlations between 
 values with efficacy and other clinical evaluations will be assessed.
Blood biomarkers related to autism (including but not limited to cytokines and miRNAs) will 
allow for exploratory immunophenotyping and for an exploratory PD evaluation. The biomarker 
data obtained from this study may also contribute to an ongoing cross-study analysis to 
investigate the relationship between ASD and phenotypes and biomarkers.
3.2.6.
JAKE System
The JAKE system is an integrated system of tools and technologies designed to optimize clinical 
trials for ASD. The JAKE System includes JAKE Sense, which collects biosensor data, and a 
reporting tool which collects caregivers’ reports on the behavior and mood of the subjects.

Caregivers will use 1 of 2 versions of a caregiver reporting tool: My JAKE (the first application 
used in this study) or My JAKE MMApp (the second application used in this study). Caregivers
will use the application which is operational during the time of their participation.
The input from My JAKE/My JAKE MMApp (which includes the ABI) and JAKE Sense will be 
processed separately. Additionally, case report form (CRF) data (study events, concomitant 
medications, demographics, etc) and data from the standard caregiver and clinician rating scales 
will be incorporated in the analysis.
See Sections 9.2.2.4 and 9.2.2.5 for information on data processing for the caregiver reporting 
tool and JAKE Sense, respectively.
It should be noted that the JAKE Sense and the individual sensors and components working as 
part of the array have been qualified for signal and processing compatibility but have not yet 
undergone full Computer Systems Validation. As such, any data derived from them should be 
considered exploratory. JAKE Sense (and its relevant processing and storage systems) are 
virtually isolated from the My JAKE/My JAKE MMApp system to ensure integrity of the 
primary endpoint measurement.
The following schematics show the overall structure of the JAKE System and its data flows for 
My JAKE (Figure 2) and My JAKE MMApp (Figure 3).

3.2.6.1.
My JAKE /My JAKE MMApp
All of the following components are included in My JAKE:

ABI: A rating scale consisting of approximately 65 questions related to the core and 
associated symptoms of ASD.

ABI-S: A shorter version of the ABI, consisting of approximately 20 questions.

Daily Tracker: In the morning, the caregiver will be asked to report on their dependent’s 
quality of sleep the night before. Additionally, the caregiver will be required to select 
3 behaviors related to ASD to track on a daily basis. After 6 PM each day, the caregiver is 
required to report on these behaviors, on their dependent’s overall type of day, and on their 
dependent’s mood, in terms of emotion and energy levels.

Journal and Event Trackers: A tracking system that allows caregivers to quickly log key 
‘events’ and information as they happen – such as a bad night’s sleep or a positive 
improvement. This can be in the form of free-text journal entries or common ASD events 
from a pick-list.

Therapy Tracker: A calendar-like ‘therapy tracker’ that allows caregivers to keep track of 
their dependent’s care-related appointments, organized in weekly or monthly views. In 
addition, it can keep track of treatments, and other therapies. It can also be used to set up and
schedule study visits.

Medical/Developmental History: A detailed medical and developmental history form 
designed to construct a picture of the subject’s ASD including treatments and other 
information, and personalize the caregiver’s view of this information.
My Jake MMApp includes only the ABI, ABI-S, and Daily Tracker. If My JAKE and My JAKE 
MMApp are not available, paper versions of the ABI, ABI-S, and Daily Tracker will be used.
Currently there are no measures which have been specifically designed to measure change in 
behavior in ASD. This impacts the development of new treatments for autism, since 
effectiveness cannot be established and compared across interventions. Many of the existing 
scales, such as the ADOS and SRS have been developed to diagnose and classify, rather than 
detect change over time. They are limited in their use as change indicators by their long recall 
periods, or lack of variability in response options. This has led to the prevalence of use of 
outcome measures such as changes in IQ, adaptive behavior, and language, which are often 
unrelated to the main focus of treatment, and/or rely on measures which are developed for 
individuals without intellectual or developmental disabilities.19
Therefore, the pressing need for research in autism is around more systematized measures, 
developed for the ASD population, which are sensitive to change over time and capable of 
capturing the heterogeneity of presentations. The ABI, its short form the ABI-S, and 
accompanying components of the JAKE System are designed to capture sufficiently variable 
presentations across all the key domains, while providing a high level of utility – effectively 
making it simple for caregivers and other observers to record critical information on 
improvement or worsening of symptoms and behaviors.

3.2.6.2.
JAKE Sense
The literature has shown that differences between TD children and autistic children can be 
detected by various physiologic and cognitive biomarkers. These modalities were chosen to 
detect differences between TD subjects and ASD subjects as well as potentially to detect 
differences between ASD subjects, treatment-induced changes and changes over time. As 
subjects improve on treatment, it is expected that biosensor signals will be more like TD 
individuals.
The following sections describe the rationale for the various sensor-experimental modalities used 
in this study, while subjects are monitored continuously (see Section 3.2.6.2.1) or assessed
through a periodic experimental battery (see Section 3.2.6.2.2).
JAKE Sense (and its hosted biosensors) are used solely for exploratory, proof-of-concept
research. While JAKE Sense may host medical devices, and while these devices are being used 
in compliance with their intended use, no portion of JAKE Sense is being used in such a way as 
to diagnose, treat, or prevent any disease or disorder, nor is the output being used in (or in 
support of) any regulatory filing (now or in the future).
3.2.6.2.1.
Continuous Biosensor
Continuous Biosensors can be worn over extended periods of time such as throughout the day or 
during sleep. They will also be worn and assessed during study visits as with the Periodic 
Biosensors below. It is expected that biosensors will provide more direct characteristics of the 
ASD population than indirect assessment via questionnaires filled in by caregivers. It is also 
expected that changes in features extracted from the biosensors will be detected prior to changes 
observed in scales.
During day/night time, recordings will be done with an actigraphy device to monitor activity. All 
biosensors were reported to have been successfully used in children (including those under 
10 years old) previously, including cohorts of individuals with ASD.1,78,134
3.2.6.2.1.1.
Actigraphy/Accelerometry
An actigraph measures activity while worn on a subject’s wrist like a watch. Based on data 
recorded during the day, time periods of child involvement in sedentary, light, moderate, and 
moderate-to-vigorous activities are expected to correlate with disease severity, where an ASD 
population is expected to spend more time in sedentary activity, with less time in light, moderate 
and moderate-to-vigorous activity than TD children of the same age.134 At the same time it was 
reported that the prevalence of sleep problems ranges from around 50% to 80% for children with 
ASD compared with 9% to 50% for a TD group.101 The use of an actigraph for sleep monitoring 
provides an easy-to-use way (in comparison to polysomnography) of sleep monitoring with 
about 90% sensitivity of sleep estimation.78
ASD is characterized by repetitive behaviors (which are included in gold standard diagnostic 
tools such as the ADOS-2 and the Autism Diagnostic Interview-Revised [ADI-R]), which 
includes body rocking, hand flapping and others.105,106,133 The frequency and durations of such

activity are usually estimated via caregivers’ reports. 
 
 
3.2.6.2.2.
Periodic Biosensors and JAKE Task Battery
Periodic Biosensors will only be worn or used for a discrete period of assessment during a study 
visit. As opposed to the Continuous Biosensor, which will be worn continuously throughout the 
treatment period, Periodic Biosensors will be assessed only during the time that the subject is 
exposed to specific visual and auditory tasks or stimuli via a computer interface (the JAKE Task 
Battery).
The Periodic Biosensor array consists of an EEG, an eye-tracker and a device for ECG 
recordings (different from the medical ECG used for drug safety evaluation). These devices have 
been extensively used in child and adolescent populations.8,23,35,37,56,115,138 In addition, the
subject’s affect (apparent emotion) will be measured with the use of a standard web camera and 
the iMotions® Biometric Research Platform Emotient™Facial Expression Analysis (FACET) 
module. The FACET module will analyze facial expressions across all task presentations, with 
particular focus on the analysis of the funny videos task.
The JAKE Task Battery includes a number of different experiments which aim to detect changes 
in core symptoms of ASD (description and rationale provided below). The experiments are 
distributed across 2 sets. Some of the experiments were developed for specific biosensors, but all 
of the biosensors are used throughout the Task Battery in order to identify new biomarkers 
across different biosensor modalities.
ECG will be monitored during the entire battery and will provide assessment of such 
characteristics as HR and HRV to study potential impairments in the autonomic nervous system 
associated with ASD.35 In addition, change in HR response to auditory stimuli will be measured 
specifically during an auditory task and a short physical challenge task. Since emerging ASD 
literature associates autonomic nervous system activity with social function, ECG recordings 
could provide a link between measurable biological activity and both social behavior and 
cognitive function.8,72,92,135
The tasks and stimuli for use with the Periodic Biosensors were chosen based on the literature 
and scientific advice to elicit physiologic and behavioral differences between ASD and TD 
populations using the various sensor modalities, and the battery was adapted following the 
ASD-002 study preliminary results.
 
 
 
 
 
The battery encompasses both static and dynamic stimuli in an 
attempt to elicit the broadest range of responses.

The tasks are divided across 2 sets. Each set includes a variety of tasks which induce behaviors 
measured by EEG, eye tracking, FACET, and HR changes, which are associated with symptom 
severity in ASD.
The entire Periodic Biosensor array will be used during each portion of the Task Battery in order 
to look for new biomarkers which could provide added value to the primary sensor for a 
particular modality. Literature suggests that some tasks have utility beyond the individual sensor. 
As such, data from all sensors on a particular task may be highly informative.
Though not part of the Periodic Biosensor array, subjects are required to wear the Continuous 
Biosensor during administration of the Task Battery.
3.2.6.2.2.1.
Periodic Biosensor of Interest: Electroencephalogram Portion
While the primary biosensor is an EEG recording device, changes in biomarkers derived from 
other modalities are also expected. This portion of the JAKE Task Battery consists of the 
following experiments:
Resting State
ASD populations exhibit an increase in brain white matter activity, which is evident from 
magnetic resonance studies.31,50 White matter reflects myelinated axons that transmit signals 
between neurons within 1 or several cortical areas. EEG recorded from electrodes on the scalp 
reflects synchronous activity among thousands of neurons in the tissue underlying a particular 
location. Thus, changes in local neural connectivity will influence changes in EEG from single 
electrodes. At the same time, EEG coherence reflects functional cortical connectivity, which 
could serve as an index of changes in long range connectivity, which could be altered due to 
changes in white matter. Those EEG indexes are best assessed during resting state in order to 
exclude EEG changes induced by any task or stimuli.
ASD subjects have memory problems: some show severely impaired memory, while others fall 
into the other extreme with 'savant' memory.83,89 Executive control of memory processing is 
mediated by the frontal cortex and also involves the integrated actions of multiple brain 
areas.20,40,44, 90,112,123 As such, abnormalities in neural connectivity may underlie memory deficits 
in ASD.102 This is especially so in theta waves in EEG during rest, which relate to memory 
processing.62
ASD subjects have increased attention to details. It was found that resting state alpha power of 
EEG recordings is linked to attention.63 As such, we may expect abnormal alpha in an ASD 
population during resting state.
ASD subjects have abnormalities in processing, perceiving and showing emotions. ASD is also 
associated with depression and anxiety. There is evidence that the frontal lobe is involved in 
emotional processing with a difference in lobes (right vs. left) for different emotions.36,46 Thus 
patterns of frontal EEG (asymmetry) may serve as an index of abnormalities in emotion 
processing and emotionally-related problems, as depression and anxiety.

ASD is also related to abnormal functioning of gamma-aminobutyric acid (GABA)-ergic tone in 
inhibitory circuitry, which influences the functioning and development of the brain.140 Abnormal 
functioning of GABA-ergic tone is thought to modulate power at high-frequency and 
low-frequency EEG bands while increasing power of middle range frequencies (alpha band).140
Event-related Potential: Faces Compared to High Autism Interest Objects
The study will use event-related potentials (ERPs) to investigate brain activity related to the 
presentation of faces (social) or objects determined to be high autism interest (HAI; 
non-social).42
According to the social motivation hypothesis, disrupted social motivation mechanisms may 
represent a primary deficit in ASD. This could include a decreased preference for social images 
and/or an increased preference for certain classes of non-social information, known as HAI 
objects.42,109
ERP studies have demonstrated differences in P300 (stimulus evaluation, novelty detection) and 
N170 (facial recognition response) between TD and ASD. Longer latency and reduced amplitude 
to faces, but not objects, have been seen in ASD.33,34,38,41,70,77
These differences may be seen in amplitudes and latencies of ERP components (especially the 
face-sensitive adult N170 component) and their hemispheric asymmetry relation, and changes in 
amplitude and latency responses may correlate with changes in symptoms.
Recently the response of the last positive potential – a centro-parietal ERP positive component at 
approximately 300 ms after stimulus onset and lasting to 1500 ms, has been found to be greater 
for HAI relative to faces in ASD, when compared with TD.13
In addition, attention to key facial features, especially the eye and mouth region, may relate to 
ASD symptoms.56 Fixation features estimated from eye-tracker data (number of fixations, total 
time spent in gazing) on key facial features, 
, will also be 
measured.
3.2.6.2.2.2.
Periodic Biosensor of Interest: Eye Tracking Portion
The eye tracking portion of the periodic biosensor array consists of following tasks:
Social Information Processing Task
The Social Information Processing Task involves actors engaging in child-directed speech and 
includes a bid for joint attention (the shared focus of 2 individuals on an object).
Visual information processing in TD subjects is reinforced with additional speech information,
which shows TD children’s ability to integrate multimodal input for faster encoding and 
recognition of faces.6,21,48,67,107,127 There is evidence that face detection is facilitated when it is 
combined with directed speech in TD infants.61,137 At the same time, ASD children are 
characterized by their limited attention to faces combined with under-responsivity to 
speech.23,26,28,87,93 Limitation in attention to faces in ASD subjects is mainly prominent for 
CCI

dynamic (videos) face stimuli, when they are presented in complex naturalistic context.55,129 It is 
possible that limited attention to faces is a direct result of increased salience of objects, which are 
of high autism interest (HAI).110,111
 
 
ASD subjects will show diminished attention assessed with the eye-tracker 
to the entire scene and spend less time monitoring the speaker’s face in general and mouth in 
particular. Instead, they will direct their attention toward the toys as well as the hand/action area.
Visual Search
ASD is characterized by interests that are restricted to some particular things (so-called HAI
objects), social difficulties and stereotyped repetitive behavior.105,106,133
 
 
 
 
 
 
Biological Motion
TD subjects show a preference for biological motion from birth.120 At the same time, children 
and adults with ASD do not show such preferences.4,86
 
 
 
 
It is also known that in TD individuals the mirror neuron system activates when they either 
watch someone perform a task or perform the task themselves.103 Response of this system is 
characterized via suppression of mu waves in EEG.103 In contrast,, in an ASD population, mirror 
neurons become active (and consequently mu waves are suppressed) only when the individual 
performs the task him- or herself.15,1
 
 
Activity Monitoring
It is known that the ability to understand intentional and goal-directed actions of others arises 
early in infancy in a TD population.5,117,129 Attention to the actions and activities of others is a 
critical component of the learning and development of cognitive and social skills.117 Attention to 
others and their actions facilitates learning about affordances, is a pre-requisite for imitation and 
emulation, and is crucial to the development of higher-level cognitive skills such as joint 
attention, 
social 
play, 
and 
the 
comprehension 
of 
intentions,

attention emerge in a regular fashion, together with their relationships with later development of 
language and theory of mind skills, argue for mutual interdependencies and suggest that common 
requirements, such as activity monitoring, may evolve together with the skills themselves.117 At 
the same time, many of the skills outlined above have been found to be impaired in the ASD
population.117,125,133,142
 
 
 
3.2.6.2.2.3.
Affect Detection Portion
It has been found that facial expressions activated via automatic or intentional mimicry influence 
corresponding emotions in controls, but that the influence of facial expressions is impaired in the 
ASD population.124 Consequently it is expected that ASD individuals will show fewer facial 
emotional responses (less variance in emotion) in response to funny videos than TD individuals. 
A more neutral flatness of affect has also been found in the activated facial expressions of 
autistic children.144
 
It is known that humans automatically mimic a variety of behaviors, including but not limited to 
emotional facial expressions.76 ASD individuals have been found not to automatically mimic 
facial expressions presented to them whereas TD individuals do.76
 
 
 
When asked to produce a specific emotion, ASD individuals are also known to produce more 
ambiguous or “bizarre” expressions, a behavior that is not apparent in the TD population.68,144
 
3.2.6.2.2.4.
HRV Portion
A review of the literature on physiological reactivity to sensory and social and emotional stimuli 
indicates that abnormalities exist for some individuals with ASD.71
In addition to looking at patterns of autonomic nervous system activity across portions of the 
Task Battery, the Auditory Processing task is designed to measure HR responsivity to auditory 
stimuli, and the physical task measures HR responsivity to change in posture from sitting to 
standing.
The toilet flush and ticking clock are presented as examples of non-biological, ecologically valid 
stimuli. They are similar to those rated in the IADs Affective Ratings of sounds. They were 
selected as they elicited similar medium level values of valence and arousal in TD adults and are 
therefore considered ‘neutral’ and non-aversive.17

Parents report increased sensory sensitivity in children with ASD and there is evidence that these 
atypical sensitivities are particularly present in the auditory domain.58,75 There are indications 
that differences in sensitivity in ASD subjects are related to underlying differences in autonomic 
nervous system responsivity, as measured by, for example, HRV.
It is also thought that these differences may be related to other behavioral differences in ASD, 
such a repetitive behaviors and anxiety.
 
There could also be different patterns observed within ASD and these differences may 
correspond with other ASD symptoms.16

JAKE Sense Workbench
The JAKE Sense Workbench is a platform that will link together and synchronize all 
components of the Periodic Biosensor collection (as well as the Continuous Biosensor) while 
presenting the JAKE Task Battery. Data collected through the JAKE Sense Workbench (JSW) is 
transmitted directly to the JAKE Sense Data Pipeline via the secure file transfer protocol 
application 
 – permitting comprehensive analysis of all biosensor data inputs and 
integration with the separately-processed manually-entered data from the caregiver reporting 
tool.
3.2.7.
Standard Instruments and Rating Scales
Throughout the study, data collected from the caregiver reporting tool and JAKE Sense will be 
compared and correlated with standard instruments and scales. The scales form a selection of the 
secondary outcome measures, in addition to contributing to the process of validation of the 
JAKE System as a tool for measuring clinical outcomes in ASD.
3.2.7.1.
Diagnostic and Classification Instruments
These instruments will be given a single time to establish the diagnosis of autism or help rule it 
out, to help classify subjects by IQ, or to rule out or rule in the presence of other psychiatric 
disorders in subjects.

Instruments for Measuring Change
The scales have been selected based on their ability to detect changes over time in the ASD 
population. As described in Section 3.2.6.1, there are no existing scales which are specifically 
designed for measuring changes in behavior in ASD. Therefore, instruments were selected based

on input from scientific advisors and current use as outcome measures in ASD interventional 
studies.
Autism Speaks commissioned 3 reports on current scales for Social Communication, Restrictive 
Repetitive Behaviors, and Anxiety, which were suitable for use in clinical trials for Autism.3,64,113
The findings of these reports, compiled by experts in the field, were influential in the
consideration of scales for comparison.
Scales were selected to ensure comparisons across all 5 domains measured by the ABI. The 
scales to be used in this study and the rationale for their use are described in the table below:
3.2.7.2.1.
Zarit Burden Interview
In addition to the behavioral scales, a measure of parent burden is also included in order to assess 
the impact of behaviors and the impact of behavioral change on the caregiver and family life. 
There are no specific scales developed to measure this aspect. The ZBI was originally developed 
to assess burden of care for dementia patients, but has also been used to assess burden in those 
who care for children and adults with ASD.22

TREATMENT ALLOCATION AND BLINDING
Treatment Allocation
Randomization 
Central randomization will be implemented in this study. At the start of the double-blind phase, 
subjects will be randomly assigned to 1 of 2 treatment groups (JNJ-42165279 or placebo) based 
on the computer-generated randomization schedule prepared before the study by, or under the 
supervision of the sponsor. The randomization will be balanced by using randomly permuted 
blocks and will be stratified by gender (male and female) and age at time of first consent 
(13-17 years and 18-35 years), with an allocation ratio of 1:1 to placebo and JNJ-42165279. 
The interactive web response system (IWRS) will assign a unique treatment code, which will 
dictate the treatment assignment and matching study drug kits for the subject. The requestor must 
use his or her own user identification and personal identification number when contacting the 
IWRS, and will then give the relevant subject details to uniquely identify the subject.
Subjects (aged 13-17 years) will be randomized until at least 8 subjects are on the active drug, 
following which screening of subjects of that age range will be temporarily paused while an 
interim PK analysis is conducted. The analysis will be performed when all 8 adolescent subjects 
have participated in the PK sampling at Week 2. Adolescent subjects already in screening may 
be randomized, and screening and randomization of subjects 18-35 years will continue as 

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
89
Status: Approved, Date: 29 September 2020
normal. Any adolescent subjects already randomized will continue per protocol. If PK samples 
are not able to be obtained from 1 of the adolescent subjects, it may be necessary to screen 
and/or randomize additional adolescent subjects. If PK results are consistent with prespecified 
parameters (see Section 11.5) screening and randomization of adolescent subjects will resume. If 
not, unless agreement is obtained from FDA to continue enrolling adolescent subjects it may be 
necessary to complete enrollment with only adult subjects. 
Blinding
The investigator will not be provided with randomization codes. The codes will be maintained 
within the IWRS, which has the functionality to allow the investigator to break the blind for an 
individual subject for reasons related to the subject’s safety.
Data that may potentially unblind the treatment assignment (eg, study medication plasma 
concentrations, plasma biomarkers) will be handled with special care to ensure that the integrity 
of the blind is maintained and the potential for bias is minimized. This can include making 
special provisions, such as segregating the data in question from view by the investigators, 
clinical team, or others as appropriate until the time of database lock and unblinding.
Under normal circumstances, the blind should not be broken until all subjects have completed 
the study and the database is finalized. Otherwise, the blind should be broken only if specific 
emergency treatment/course of action would be dictated by knowing the treatment status of the 
subject. In such cases, the investigator may in an emergency determine the identity of the 
treatment by contacting the IWRS. While the responsibility to break the intervention code in 
emergency situations resides solely with the investigator, it is recommended that the investigator 
contact the sponsor or its designee if possible to discuss the particular situation, before breaking 
the blind. In the event the blind is broken, the sponsor must be informed as soon as possible. The 
date, time, and reason for the unblinding must be documented in the appropriate section of the 
CRF, and in the source document. The documentation received from the IWRS indicating the 
code break must be retained with the subject's source documents in a secure manner. 
Subjects who have had their treatment assignment unblinded should continue to return for 
required follow up evaluations.
In general, randomization codes will be disclosed fully only if the study is completed and the 
clinical database is closed. However, if an interim data review by the Data Monitoring 
Committee (DMC) is specified, the randomization codes and, if required, the translation of 
randomization codes into treatment and control groups will be disclosed to those authorized and 
only for those subjects included in the interim review.

DOSAGE AND ADMINISTRATION
Following Protocol Amendment 5, subjects will self-administer double-blind study medication 
twice daily for 12 weeks. Study medication will be provided as JNJ-42165279 25 mg tablets, or 
matching placebo, packaged in bottles. All tablets (JNJ-42165279 /placebo) are identical in 
appearance.

On all visits in the treatment phase, study medication will be taken at the clinic. Treatment Phase 
visits should be scheduled to occur in the morning, and the dose administered in the clinic should 
be the first dose of the day for each subject. Dosing should occur after all subject-related 
procedures, except as noted for blood draws, when feasible. Dosing must occur after 
confirmation of eligibility and subjects’ baseline safety assessments on Day 1 and after 
administration of the JAKE Task Battery at all applicable visits. On all other days between visits, 
subjects will be instructed to take their study medication at home once in the morning and once 
in the evening, with as close as possible to a 12-hour interval between dosings. No more than 
2 pills should be taken in one day (defined here as midnight to midnight). There should be at 
least 6 hours between doses; if this is not possible, a dose should be skipped. Subjects should be 
informed of the importance of taking the evening dose on the day prior to the Week 2 and 
12 visits as close as possible to their routine evening dose time. 
Diaries will be provided to subjects/caregivers to record dates of non-compliance (missed doses 
or >2 pills taken), as well as the time of morning and evening dosings on the day prior to the 
Week 2 and 12 visits. 
A study-site investigational product manual including instructions for dispensing, storage (on site 
and at home) and intake of the study medication will be supplied to the study site. 
Study-site personnel will instruct subjects on how to store study drug for at-home use as 
indicated for this protocol.
In case of any change in dose levels prior to study start or during the study the responsible 
Ethical Committee(s) and Health Authorities, if applicable, will be notified.
7.
TREATMENT COMPLIANCE
The investigator or designated study-site personnel will maintain a log of all study drug 
dispensed and returned. Drug supplies for each subject will be inventoried and accounted for 
throughout the study. 
Study drug will be self-administered by subjects. As such the number of study drug tablets 
dispensed will be recorded and compared with the number returned. 
At study visits on which the dose is to be held, study drug will be self-administered on site, 
which will be witnessed by designated study-site personnel at the study sites.
Subjects will receive instructions on compliance with study drug administration upon study 
medication (bottle) dispensing. During the course of the study, the investigator or designated 
study-site personnel will be responsible for providing additional instruction to re-educate any 
subject who is not compliant with taking the study drug.
8.
PRESTUDY AND CONCOMITANT THERAPY
Prestudy therapies administered up to 3 months before screening must be recorded at screening. 

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
91
Status: Approved, Date: 29 September 2020
Concomitant therapies must be recorded throughout the study beginning with signing of the 
initial informed consent until the end-of-study visit (Follow up). Concomitant therapies should 
also be recorded beyond this time only in conjunction with new or worsening adverse events 
until resolution of the event.
All therapies (prescription or over-the-counter medications, including vaccines, vitamins, herbal 
supplements; non-pharmacologic therapies such as electrical stimulation, acupuncture, special 
diets, exercise regimens) different from the study drug must be recorded in the CRF. 
Modification of an effective preexisting therapy should not be made for the explicit purpose of 
entering a subject into the study.
Any pharmacologic, diet, or behavioral intervention for the core or associated symptoms of ASD 
such as but not limited to an ABA program, PRT, TEACCH, Floor Time and DIR, RDI, Early 
Start Denver Model, Discrete Trial Training or a social skills program whether school-based or 
not must:
A) Have begun at least 1 month prior to the baseline visit and continue unchanged through 
the double-blind period, or
B) Have ended at least 1 month prior to the baseline visit
If such therapy is started, discontinued or changed substantially during the course of the 
double-blind study the subject should be discontinued.
Subject should not take any sedating medications on the day of the Test Battery (other than 
preexisting daily medications) and should not consume caffeine within 2 hours prior to the 
battery.
Moderate and strong inducers or inhibitors of CYP3A4 are prohibited through the end of the 
posttreatment phase. Attachment 2 provides examples of moderate and strong inducers or
inhibitors of CYP3A4. The investigator should evaluate all prestudy and concomitant 
medications to assess whether they are moderate or strong inducers or inhibitors of CYP3A4 and 
consult with the Sponsor if unsure. 
On biomarker blood collection days, subjects should be informed to refrain from use of NSAID
medications for 24 hours before their scheduled visit. This is because the use of NSAIDs may 
impact biomarker measurements, specifically via altering circulating and inducible cytokine 
levels. In addition, NSAIDs also have been reported to inhibit FAAH directly so there is a 
particular need in FAAH studies to restrict their use. Any use of NSAIDs within 24 hours prior 
to the visit should be recorded on the CRF or lab requisition form.
The sponsor must be notified in advance (or as soon as possible thereafter) of any instances in 
which prohibited therapies are administered.

Study Procedures
9.1.1.
Overview
The Time and Events Schedule summarizes the visits as well as the frequency and timing of 
assessments applicable to this study. A visit window of ±3 calendar days will be allowed for all
visits after Day 1, unless otherwise indicated in the Time and Events Schedule. All visits are in 
principle single day visits; however, they may be performed over multiple days within the 
allowed visit window in case of logistical issues or subject’s preference. Visits during the 
treatment period should be scheduled on the same type of day (weekday vs weekend).
Information regarding collection, handling, shipment, and labeling of biological samples 
(including safety labs) will be provided in a separate lab manual. Any changes to the lab manual 
will not result in a protocol amendment.
In the event of abnormal safety findings during the conduct of the study, additional 
measurements may be made immediately and subsequently at a frequency considered 
appropriate by the attending physician.
The person that will serve as the designated caregiver for the trial will be determined at 
screening. This person will perform all caregiver responsibilities described in this protocol, 
including attending all study visits and completing all caregiver assessments.
The time points for individual measures may be changed by the sponsor (with or without 
affecting the overall frequency of these investigations) prior to and during the study based on 
newly obtained data (eg, interim analysis, DMC) to allow for optimal fit to the actual safety or 
PK/PD profile of the study drug. This modification may result in a change in the overall 
frequency of the individual measures (eg, safety measures, blood samplings) provided the 
maximal total blood volume collected per subject defined will not be exceeded. Such 
modifications, where performed only to allow optimal fit to the actual safety, PK/PD profile of 
the study drug, will not be considered to be an (substantial) amendment to the protocol.
Additional serum or urine pregnancy tests may be performed, as determined necessary by the 
investigator or required by local regulation, to establish the absence of pregnancy at any time 
during the subject's participation in the study.
The following describes the order of procedures at study visits:

The order of blood draws versus dosing, when both occur at a visit, is as follows (see the 
Time and Events Schedule for further information):

On Day 1, blood samples will be collected postdose. 

At the Week 2 and 12 visits, blood samples will be collected both prior to and after 
dosing.

At the Week 4 and 8 visits, blood samples may be collected before or after dosing.

93
Status: Approved, Date: 29 September 2020

The order of procedures, other than the order of blood draws relative to dosing, is as 
follows:

On Day 1, all procedures required for determination of eligibility and all safety 
assessments must be completed prior to randomization and dosing.

For all visits, including screening, all subject-related procedures should be completed 
prior to blood sample collection.

It is recommended that dosing at study visits occur after all subject-related procedures. 

For each subject, the JAKE Task Battery should be conducted at approximately the 
same time of day, when feasible, and must be completed prior to blood draws and 
dosing.
Venous blood will be collected for all blood-based analysis. Actual dates and times of 
assessments will be recorded in the source documentation and CRF or lab requisition form. The 
exact times for each blood draw will be recorded in the lab requisition form. If blood sampling or 
vital sign measurement is scheduled for the same time point as ECG recording, the procedures 
should preferably be performed in the following order: ECG(s), vital signs, blood draw. The 
order of multiple assessments within 1 protocol time point should also be the same throughout 
the study. Blood may be drawn by using a cannula or by venipuncture. The volume of blood to 
be collected from each subject is summarized in Table 1. For each subject, the maximum amount 
of blood drawn in this study will not exceed 200 mL.

9.1.2.
Screening Phase
Before any study specific procedures are conducted and following an explanation of the purpose 
and risks of the study, written consent, and if applicable, assent, will be obtained
(see Section 16.2.3, Informed Consent and Assent Form, for further information).
Subjects will be screened within 26 days prior to Day 1 of the double-blind period, to assess their 
eligibility for the study, according to the inclusion and exclusion criteria.
Recording of adverse events/concomitant medication will start following consent and will 
continue until completion of the study.
During screening, assessments/procedures will be performed as described in the Time and 
Events Schedule.
If the results of the serum chemistry panel, hematology, or urinalysis are outside the normal 
reference ranges, the subject may be included only if the investigator judges the abnormalities or 
deviations from normal to be not clinically significant.
Retesting of abnormal laboratory values that may lead to exclusion will be allowed one time.
Retesting will take place during an unscheduled visit in the screening phase or at the second 
screening visit.
Urine drug screens to determine eligibility may be repeated once, at the discretion of the 
investigator.
Eye calibration may be repeated during the screening period if “good” calibration is not achieved 
at the first screening visit.
If a subject is not able to complete all screening procedures within the screening window, or does 
not meet all inclusion and exclusion criteria (ie, is a screen failure), but at some time in the future 
is expected to meet the subject eligibility criteria, the subject may be rescreened on 1 occasion 
only. Subjects who are rescreened will be assigned a new subject number, undergo the informed 
consent process, and then restart a new screening phase.
9.1.3.
Double-Blind Treatment Phase
Throughout the treatment phase, study medication will be dispensed at study visits and subjects 
will self-administer the medication as outlined in Section 6, Dosage and Administration. Clinic 
visits should be scheduled for the morning, as the in-clinic dosing should be a subject’s first dose 
of the day.

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
95
Status: Approved, Date: 29 September 2020
On Day 1, subjects who successfully complete the screening phase will visit the clinical site/unit 
to be randomized on Day 1 of the double-blind phase. Prior to dosing, eligibility will be 
confirmed and the baseline safety assessments and the JAKE Task Battery will be performed as 
described in the Time and Events Schedule.
During the double-blind treatment period, following Day 1, subjects will return to the 
investigational site at Week 2 (Day 15), Week 4 (Day 29), Week 8 (Day 57), and Week 12 
(Day 85). Assessments will be performed as specified in the Time and Events Schedule.
9.1.4.
Posttreatment Phase (Follow up)
At 14 days (±1 week) following last dosing (Week 12), subjects will return to the clinical site for 
a safety follow up visit. The procedures to be completed during the follow up visit are listed in 
the Time and Events Schedule.
Investigators may re-contact the subject to obtain long-term follow up information to determine 
the subject's safety or survival status (refer to Section 16.2.3, Informed Consent).

Caregiver Reporting Tool: Modules and Components
My JAKE and My JAKE MMApp are two applications containing the caregiver reporting tool 
that can be used by the caregiver during the study to enter information about the behavior and 
mood of the subjects. Caregivers will register and use either the first application of the reporting 
tool, My JAKE, or the second application of the tool, My JAKE MMApp, dependent upon the 
application which is operational at the time. If neither version is available, caregivers will record 
information on paper forms as described below.
My JAKE encompasses various modules for use by clinicians, caregivers, and the sponsor. My 
JAKE MMApp is for use by caregivers and the sponsor. Both applications are accessible through 
most modern web browsers (“My JAKE Web”), as well as mobile devices (“My JAKE Mobile”). 
My JAKE or My JAKE MMApp is used throughout the study. Specific instructions for certain 
modules are below.
Not all modules described are available for both My JAKE Web and My JAKE Mobile 
interfaces.
Some modules in My JAKE are not available in My JAKE MMApp nor on paper forms. Table 2

It is understood that caregivers of independent, adult subjects may not be able to enter the same 
amount into the caregiver reporting tool as caregivers of subjects who live with them.
Site and institution personnel will not modify, adjust, troubleshoot, change or alter the hardware 
or software of the JAKE System unless instructed to do so by or under the supervision of the 
sponsor.
Caregivers using My JAKE should be instructed not to revoke site or sponsor’s access to My 
JAKE and Microsoft HealthVault without investigator approval to do so.
9.2.2.1.1.
ABI
The ABI is a series of approximately 65 questions related to the core and associated symptoms of 
ASD. Questions are answered on 1 of 2 possible dimensions, quality (how well a person carries 
out a particular behavior) or frequency (how often a particular behavior occurs).
The ABI was developed by review of existing instruments in consultation with experts in the 
field and testing in the target population. The current versions of the ABI, ABI-S, and Autism 
Behavior Inventory-Clinician interview (ABI-C) are a result of a statistical and clinical review 
process, and qualitative review and feedback from users, including cognitive interviewing.
The development of the ABI adhered to the following FDA guidelines, (1) Precise definition of 
the target construct, (2) The need for the new measure and how it will enhance the substantive 
knowledge base, (3) Initial pool of items was submitted to expert review,143 (4) Identification and 
justification for sampling strategy, (5) Used Exploratory Factor Analysis (EFA) to assess the 
underlying factor structure to refine item pool,30 (6) Description of covariance and correlation 
matrix, (7) Use of psychometric techniques during scale refinement that included Item 
Discrimination, Item Difficulty, Correlation if items were deleted, Differential Item Functioning 
(DIF): a Rasch Analysis approach. 
Validation of the ABI began in ASD-001, where in a small sample of around 25 parents and 
20 clinician ratings, good test-retest reliability was found. Correlation between the ABI and 
validated instruments measuring similar domains was also good, and there was divergence 
between scales which were not expected to correlate. Validation, including an assessment of 
sensitivity to change, continued in the ASD-002 study.
The full ABI will be completed by the primary caregiver at screening, Day 1 (predose), Week 4,
Week 8, and Week 12. It should be completed at the site and on the same day as it is begun. 
The ABI-S is a shorter version of the ABI with approximately 20 items. The caregiver will 
complete the ABI-S on Week 2 (site), Week 6 (home), and Week 10 (home) as outlined in the 
Time and Events Schedule.
Following a caregiver interview, the PI or delegate will complete the ABI-C on visits listed in 
the Time and Events Schedule.

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
98
Status: Approved, Date: 29 September 2020
For each subject, the ABI and ABI-S should be completed by the same caregiver, and the ABI-C 
should be completed by the same site personnel, at all administrations.
ABI-C
The ABI-C covers the domains and subdomains of the ABI-S and is intended for completion by 
the clinician following an interview with the caregiver and observation or interview with the 
individual with ASD, as appropriate. The clinician is required to rate the severity of behaviors or 
level of impairment observed or described on a scale of 1 to 7, where 1 indicates no impairment 
of behavior and 7 indicates severe difficulties with an area of functioning. There are 14 items 
across each of the 5 domains. The ABI-C is completed on paper. See Attachment 3 for a 
representative example of this instrument.
9.2.2.1.2.
Daily Tracker
The caregivers are required to select 3 items to track on a daily basis. Following completion of 
the ABI at the screening visit, a clinician at the site will discuss possible items to track with the 
caregivers and help them with their selection. Caregivers will have the opportunity to change the 
behaviors they track at the baseline visit. After this point they are required to track the same 
behaviors for the duration of the study. After 6 pm each day, caregivers are required to report on 
these behaviors, as well as report on subjects’ overall type of day, using an 8-point scale, ranging 
from ‘troubling’ to ‘encouraging’. 
A Mood Report is completed after 6 pm each day. The report allows the caregiver an opportunity 
to report the subject’s state, in terms of valence and arousal levels. It is presented twice, 
requiring caregivers to: 1) report subject’s overall mood for that day and 2) report the subject’s 
most extreme mood for that day.
In addition, each morning the caregiver will be asked to report on how well the subject slept the 
previous night using the same 8-point scale used for behavior ratings.
9.2.2.1.3.
Journal and Event Trackers
This module will:

Allow ad hoc free-text entry by caregivers.

Provide an interface for tracking both events and journal entries (tantrum, stereotypy, social 
interaction, etc.) as they occur. Caregivers will also be able to track progress towards a 
particular target behavior that they have entered.

Keep track of items of interest, including sleep problems, seizures and diet on a daily basis.
Events can be reported on a daily basis throughout the study, either as they occur or at a later 
stage. The clinician at the site will discuss 1 or 2 specific behaviors which the caregiver will aim 
to track using the event trackers. The caregiver will be encouraged to record 3 instances of these 
behaviors, as they happen, each week. Use of the journal will be encouraged but is considered 
optional.

Status: Approved, Date: 29 September 2020
In My JAKE, the Mood Report can be completed at any time through the Events Tracker, in 
addition to reporting within the Daily Tracker. 
9.2.2.1.4.
Therapy Tracker
This module will track the subject’s various medical appointments, treatments, and other 
therapies. It can also be used to set up and schedule study visits with the parent or caregiver. Use 
of the therapy tracker will be encouraged but is considered optional.
9.2.2.1.5.
Medical/Developmental History
This module is to be filled out by caregivers (with assistance, if needed) during the 
screening/on-boarding phase of the study. Certain sections, such as the developmental milestones 
may continue to be edited throughout the study.
If the Medical/Development History section is not completed by the caregiver, the site is 
responsible for ensuring completion of required fields in My JAKE.
9.2.2.2.
JAKE Sense
Biosensors will be evaluated and used as per the Time and Events Schedules and descriptions 
below.
9.2.2.2.1.
Continuous Biosensor
Continuous Biosensors can be worn over extended periods of time such as throughout the day or 
during sleep. The Continuous Biosensor will also be worn and assessed during study visits as 
with the Periodic Biosensors below. Description of the Continuous Biosensor and its use in this 
study is provided below.
The Continuous Biosensor is the ActiGraph GT9X Link Wristband. The ActiGraph Link is a 
wireless wristband biosensor that measures activity. This sensor should be worn continuously 
except when necessary to remove it for charging or other reasons.
The subject will be required to wear the Continuous Biosensor during every site visit so that data 
can be collected afterwards by study site personnel. 
ActiGraph Link is a recognized medical device in the United States - 510(k) number K040554 
Code: GWQ. While this device is being used in compliance with its intended use, it is not being 
used in such a way as to diagnose, treat, or prevent any disease, nor is its output being used in (or 
in support of) any regulatory filing (now or in the future).
9.2.2.2.2.
Periodic Biosensors
Periodic Biosensors will only be worn or used for a discrete period of assessment at a study visit. 
As opposed to the Continuous Biosensors, which will also be worn during normal daily 
activities, Periodic Biosensors will be assessed during the time that the subject is exposed to 
specific visual and auditory tasks or stimuli via a computer interface (the JAKE Task Battery;

Actiwave Cardio Single-Channel ECG
Heart rate data will be collected using the Actiwave Cardio Single-Channel Electrocardiogram 
(patch); (http://www.camntech.com/products/actiwave-cardio/actiwave-cardio-overview).
The 
Actiwave Cardio is a water-resistant ultra-miniature single channel ECG waveform recorder. It 
consists of 2 electrodes connected by a short lead which simply clip onto 2 standard ECG pads 
worn on the chest. It also contains a tri-axial accelerometer, the signal from which allows the 
user to determine resting body position. Adhesive, disposable electrodes are applied to the 
subject’s chest – the device is then clipped to the electrodes.
The Actiwave Cardio is a recognized medical device in the United States - 510(k) number 
K100266 Code: MWJ. While this device is being used in compliance with its intended use, it is 
not being used in such a way as to diagnose, treat, or prevent any disease, nor is its output being 
used in (or in support of) any regulatory filing (now or in the future).
NOTE: The Actiwave Cardio is used only for JAKE Sense Periodic Biosensor evaluation and is

software application platform iMotions® Biometric Research Platform (formerly known as 
Attention Tool). Subjects will use all Periodic Biosensors throughout all components of the Task 
Battery, though certain components are focused on specific sensors as indicated by the section 
headers. A subset of these sensors will interface directly with iMotions® Biometric Research 
Platform, while others will use their own proprietary software to operate. 
Additionally, subjects will continue wearing the Continuous Biosensor during administration of 
the Task Battery. Tasks and stimuli will be presented on a computer monitor and may require 
interaction as described below. The tasks are presented in 2 sets of approximately 13 minutes. 
Breaks are permitted between sets and as necessary within a set (though this is discouraged). 
Devices should continue to be worn during all breaks.
Images/video within a task will be counterbalanced for order between subjects.

Caregiver Reporting Tool: Data Processing 
The JAKE Data Pipeline is an internal set of tools designed specifically to handle data that is 
entered through My JAKE. While My JAKE will have access to all data contained within a 
subject’s Microsoft HealthVault account, only a subset of this information is collected and 
archived by the sponsor through the My JAKE Data Pipeline. 
My JAKE MMApp Data Processing incorporates an integrated set of tools designed specifically 
to handle data that is entered through My JAKE MMApp. The sponsor will have full access to all 
information entered through My JAKE MMApp. 
The sponsor will use the information collected through the My JAKE Data Pipeline and My 
JAKE MMApp to track study progress and outcomes and perform related study analysis. This 
information may contain limited personal “identifiers.” The information collected and archived 
may be shared with other members of the Johnson & Johnson family of companies, its 
contractors and consultants, and regulatory authorities such as FDA.
To ensure that access to protected health information (PHI) stored in Microsoft HealthVault is 
limited, high risk fields are filtered out during the My JAKE Data Pipeline data collection 
procedure. These fields include (but are not limited to) names, phone-numbers, street and email

JAKE Sense Data Pipeline
The JAKE Sense Data Pipeline is an internal set of tools designed specifically to handle data 
collected by JAKE Sense. First, packages are archived to ensure traceability of derived analyses. 
Second, a series of utilities scans the packages to produce a series of extracted features in the 
form of flat .CSV-formatted files. Finally, the files are stored in a secured server file share (and 
combined with outputs from the My JAKE Data Pipeline) for the purpose of exploratory, POC
data mining.
The information collected and archived via the JAKE Sense Data Pipeline is subject to the same 
treatment and sharing policies as data collected and archived via the My JAKE Data Pipeline.

Standard Instruments and Scales
The diagnosis of ASD will also be established or confirmed via standard instruments and scales. 
Subjects will be required to have a formal DSM-5 diagnosis of ASD using the ADOS-2. An 
ADOS-2 completed within 24 months prior to the screening visit is acceptable but the item 
responses must be available for entry into the study eCRF. Assessments will follow the Time and 
Events Schedule. All caregiver rating scales should be completed by the primary caregiver.
Preferably the same person should complete the scales throughout the study.
9.2.2.6.1.
Autism Diagnostic Observation Schedule™, Second Edition
The ADOS-2 is a validated scale that allows a reliable diagnosis of ASD across age, 
developmental level, and language skills. One of the 4 ADOS-2 modules should be selected 
according to the publisher’s manual. Module 4 should be scored according to the algorithm 
published in Hus et al, 2014.53

See Attachment 11 for a representative example of each of these instruments. 
9.2.2.6.9.
Caregiver Global Impression of Severity
The Caregiver GI-S is a single-item instrument that asks caregivers to rate their overall 
impression of the severity of their child’s ASD symptoms at baseline and per the Time and 
Events Schedule. 
9.2.2.6.10.
Caregiver Assessment of Treatment
The Caregiver Assessment of Treatment is a 3-item questionnaire completed at the end of the 
treatment period. Caregivers rate their global impression of improvement in their child’s autism, 
whether there was improvement in specific symptoms, and their interest in having their child
continue the study medication.
See Attachment 14 for a representative example of this questionnaire.  
9.2.2.6.11.
Self-Assessment of Improvement
The subject will be asked to give his/her impression of overall improvement in ASD symptoms 
using a single-item instrument, the Self GI-I.
9.2.2.6.12.
Evaluation of JAKE
At the end of the treatment period caregivers will provide feedback on their experience with the 
JAKE system using a questionnaire. This is not a part of the evaluation of treatment, but may 
provide useful feedback for future use of the JAKE system. 
9.2.2.7.
JAKE Help/Manuals
JAKE will include robust help for sites and caregivers for all components of the system. My 
JAKE will display only the appropriate content to the logged in account (ie, help sections 
intended for site personnel are not accessible to subjects or caregivers). The help system will 
contain (but is not limited to) general information, troubleshooting steps, and instructional guides 
in the form of quick reference guides, training videos, or checklists for each JAKE System 
component. My JAKE MMApp will contain a reduced set of checklists appropriate for the 
caregiver. Study sites are expected to be proficient in using the help system and following all of 
the steps outlined in the instructional guides prior to enrolling subjects. Training will be 
conducted on the use of the help system, instructional guides, and their related components.
A hardcopy of the JAKE manual will be provided to clinical sites, and will be available online in 
My JAKE. Caregivers will be given a hardcopy of a Caregiver Guide, which will also be 
available online in both My JAKE and My JAKE MMApp. These documents and / or applicable 

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6

Status: Approved, Date: 29 September 2020
help sections may be updated during the trial. Any updates will be proactively communicated to 
sites. An interactive, site-only, on-line version of the full help manual will be available.
There will also be a toll-free helpline available for sites and caregivers. Callers will be instructed 
not to provide their name, call-back numbers, or any other identifiable information to protect 
subject and caregiver identity. The toll-free helpline is operated by employees and contractors of
the sponsor.
9.2.2.8.
National Database for Autism Research/Global Unique ID
Subjects will participate in NDAR data sharing. Prior to their first subject each PI must apply to 
NDAR (to obtain access to the GUID creation tool). During screening, the site will generate a 
GUID for each subject using PHI such as name, place of birth and date of birth. PHI is 18 classes 
of information defined by US law and regulation that can be used to identify an individual. The 
storage and transmittal of PHI is restricted by US regulation. This PHI does not leave the site and 
is not transmitted to the sponsor or to National Institutes of Health (NIH). The GUID cannot be 
used to recreate the PHI. The site will enter the GUID into the sponsor’s eCRF system.
There are 2 components to NDAR.
1. The sponsor may use the GUID to access data held by NDAR on individual subjects that has 
been shared with NDAR from other research projects and studies. Such data will be 
de-identified and will only be held in NDAR if the subject or legally appointed representative 
had granted consent in an Institutional Review Board (IRB) approved study for it to be sent 
to NDAR and shared with other researchers
2. Data from this study may be submitted to the NDAR using the GUID. NDAR is a computer 
system run by the National Institutes of Health that allows researchers studying autism to 
collect and share information with each other. With an easier way to share, researchers hope 
to learn new and important things about autism more quickly than before. 
Data obtained from and shared with NDAR will be that of subjects in this study. The sponsor 
will be able to obtain additional data on subjects in this study from NDAR and potentially use 
that data to learn more about autism and improve the JAKE System.
During and after the study, the sponsor may send information about subject’s health and 
behavior and any other data gathered in this study to NDAR. All data sent to NDAR will be 
provided through the JAKE Sense Data Pipeline and first de-identified in compliance with 
45 CFR 164.514(b)(1). Only the NDAR GUID will link data from different sources to unique 
subjects. Researchers nationwide can then file an application with the NIH to obtain access to 
study data for research purposes. Experts at the NIH with expertise in the protection of health 
and science information will review every request carefully to minimize risks to subjects’ 
privacy.
9.3.
Biomarker Evaluations
During the study, the following PD evaluations will be performed at the time points indicated in 
the Time and Events schedule: plasma concentrations of 
.
CCI

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
108
Status: Approved, Date: 29 September 2020
Additionally, blood biomarkers related to autism (including but not limited to cytokines and 
miRNAs) will be investigated to allow for exploratory immunophenotyping and for an
exploratory PD evaluation. Biomarkers may be added or deleted based on scientific information 
or technical innovations under the condition that the total volume of blood collected will not be 
increased.
The biomarker data obtained from this study may also be included in an ongoing cross-study 
analysis to investigate the relationship between ASD and phenotypes and biomarkers.
For visits that include biomarker sample collection, subjects should be advised to follow a 
low-fat diet for at least 8 hours prior to their scheduled visit. Subjects should be advised to 
refrain from strenuous exercise and use of NSAID medications for 24 hours before their 
scheduled visit. This is because the use of NSAIDs may impact biomarker measurements, 
specifically via altering circulating and inducible cytokine levels. In addition, NSAIDs also have 
been reported to inhibit FAAH directly so there is a particular need in FAAH studies to restrict 
their use. Information regarding compliance with these restrictions should be recorded on the 
CRF or lab requisition form.
9.4.
Pharmacokinetics
9.4.1.
Evaluations 
Venous blood samples for analysis of JNJ-42165279 in plasma will be collected at the 
time points indicated in the Time and Events Schedule. 
Blood samples will be used to evaluate the plasma PK of JNJ-42165279. Samples collected for 
analyses of JNJ-42165279 plasma concentration may additionally be used to evaluate safety or 
efficacy aspects that address concerns arising during or after the study period or for the 
evaluation of relevant biomarkers. Genetic analyses will not be performed on these plasma 
samples. Subject confidentiality will be maintained.
The date and time of study drug administration in the clinic on Day 1, Week 2 and Week 12 
visits, and the day prior to the Week 2 and 12 visits (both morning and evening doses) must be 
accurately recorded. Subjects will be instructed to take the dose of study drug at the Week 2 and 
12 visits at the clinical site after collection of the first PK blood sample on those days.
9.4.2.
Analytical Procedures
Plasma will be analyzed to determine concentrations of JNJ-42165279 using a validated, 
specific, and sensitive liquid chromatography-tandem mass spectrometry method by or under the 
supervision of the sponsor. 
If required, some plasma samples may be analyzed to document the presence of circulating 
metabolites using a qualified research method. In addition, plasma samples may be stored for 
future analysis of protein binding and the metabolite profile.

Status: Approved, Date: 29 September 2020
9.4.3.
Pharmacokinetic Parameters
The oral clearance and apparent distribution volume of JNJ-42165279 are assumed to be 
logarithmically distributed. The intersubject variabilities (expressed as percent coefficient of 
variation) of these parameters are 35.9% and 18.1%, respectively, based on previously conducted
population analyses that used pooled PK data from studies with JNJ-42165279 in adults. 
Assuming a similar PK variability (ie, 35.9%) for subjects who are 13 to 18 years of age and a 
sample size of 15 subjects, the probability that the 95% confidence interval for the geometric 
mean of each PK parameter will fall within 71% to 140% of the true geometric mean is 80%.
The plasma concentration-time data of JNJ-42165279 will be analyzed using population PK 
modeling. Typical population values of basic PK parameters (eg, apparent clearance, apparent 
distribution volume) will be estimated together with the inter-individual variability. Effects of 
subject demographics, laboratory parameter values, and other covariates on the PK of 
JNJ-42165279 will be explored. The results of the population PK analyses may be reported 
separately.
9.5.
Pharmacogenomic (DNA) Evaluations
A pharmacogenomic blood sample will be collected from all eligible subjects. Deoxyribonucleic 
acid (DNA) samples will be analyzed for FAAH gene variants. Additional analyses may be 
conducted if it is hypothesized that this may help resolve issues with the clinical data. DNA
samples may also be used for the identification of genetic and/or epigenetic factors that may 
influence the PK, PD, efficacy, safety and/or tolerability of JNJ-42165279, and for exploratory 
genetic and/or epigenetic analyses, including of autism.
DNA samples will be used for research related to JNJ-42165279 or ASD. They may also be used 
to develop tests/assays related to JNJ-42165279 or ASD. Pharmacogenomic research may consist 
of the analysis of 1 or more candidate genes or of the analysis of genetic markers throughout the 
genome or analysis of the entire genome (as appropriate) in relation to JNJ-42165279 or ASD 
clinical endpoints.
The pharmacogenomics data obtained from this study may also be included in an ongoing 
cross-study analysis to investigate the relationship between ASD and phenotypes and 
biomarkers.
9.6.
Safety Evaluations
During the study, regular safety assessments will be performed as listed in the Time and Events 
Schedule. These safety assessments include but are not limited to: vital signs, electrocardiogram 
(ECG), physical examination, adverse events, Columbia Suicide Severity Rating Scale 
(C-SSRS), Aberrant Behavior Checklist-Irritability Subscale (ABC-I), and clinical laboratory 
tests. 
Any clinically relevant changes occurring during the study must be recorded on the Adverse 
Event section of the case report form (CRF).

Status: Approved, Date: 29 September 2020
Any clinically significant abnormalities persisting at the end of the study/early withdrawal will 
be followed by the investigator until resolution or until a clinically stable endpoint is reached.
9.6.1.
Adverse Events
Adverse events will be reported by the subject (or when appropriate, by a caregiver, surrogate, or 
the subject's legally-acceptable representative) from the time informed consent is signed until 
completion of the subject’s last study-related procedure. Adverse events will be followed by the 
investigator as specified in Section 12, Adverse Event Reporting.
9.6.2.
Suicidality Evaluation
The C-SSRS and/or the ABC-I will be used in the evaluation of suicidality, as indicated below:

At screening, the investigator will determine if evaluation of suicidality using the C-SSRS is 
feasible for each subject. 

If feasible, both the C-SSRS and ABC-I should be performed at screening. 

If the investigator determines that the C-SSRS is not feasible at screening, only the ABC-I 
will be used at screening and throughout the study. 

If both were used at screening, then both should continue to be used throughout the study 
unless the investigator determines that it is no longer feasible to use the C-SSRS; in this
case, the ABC-I should be used alone for the remainder of the trial. 

The irritability subscale of the ABC (ie, ABC-I) will be collected at every visit except the 
second screening visit, either as part of the full ABC or alone. This is irrespective of whether 
the C-SSRS is performed.

Note: The full ABC includes the ABC-I subscale. Thus, administration of the ABC-I 
subscale alone is only needed when the full ABC is not performed.
The results of the C-SSRS and ABC-I should be reviewed by the investigator at each visit 
collected prior to the subject’s departure. If a suicide-related thought or behavior is identified at 
any time or if there are any other concerning findings or changes, a thorough evaluation will be 
performed by a study physician, and appropriate medical care will be provided.
9.6.2.1.
Columbia Suicide Severity Rating Scale
Consistent with regulatory guidance, any occurrence of suicide-related thoughts and behaviors 
will be assessed. An interview to assess the risk of suicidal ideation and behavior will be 
conducted at the time points listed in the Time and Events Schedule. 
The C-SSRS is a measure of the spectrum of suicidal ideation and behavior that was developed 
in the National Institute of Mental Health Treatment of Adolescent Suicide Attempters Study to 
assess severity and track suicidal events through any treatment.97 The C-SSRS is a clinical 
interview providing a summary of both ideation and behavior that can be administered during 
any evaluation or risk assessment to identify the occurrence and intensity of suicidal thoughts 
and suicidal behaviors. It can also be used during treatment to monitor for clinical worsening.

Status: Approved, Date: 29 September 2020
Both pediatric and adult versions of the C-SSRS are available and the investigator should use the 
appropriate version per C-SSRS instructions and training.
The Baseline/Screening version of the C-SSRS will be used at screening and the Since the Last 
Visit version will be used at all other visits.
See Attachment 12
and
Attachment 13
for representative examples of the C-SSRS 
(Baseline/Screening) and C-SSRS (Since Last Visit), respectively.

Aberrant Behavior Checklist - Irritability Subscale
The ABC-I is a subscale of the ABC (described in Section 9.2.2.6.7) focusing on irritability, 
aggression and self-injurious behavior. As the C-SSRS may not be appropriate for all subjects in 
this study, the ABC-I may be used as a substitute as per instructions in Section 9.6.2, Suicidality 
Evaluation.
9.6.3.
Vital Signs
Sitting vital signs (body temperature, pulse/HR, blood pressure) will be collected at the time 
points indicated in the Time and Events Schedule.
9.6.4.
Electrocardiogram
Twelve-lead ECGs will be collected at the time points listed in the Time and Events Schedule.12
At all time points, triplicate ECGs are required. The individual ECG tracings should be obtained 
as closely as possible in succession, but no more than 2 minutes apart. The full set of triplicates 
should be completed in less than 4 minutes. It should be noted that the single-lead ECG used 
during the JAKE Task Battery is not used as a substitute for the 12-lead recorder.
During the study, the clinical investigator will review the ECG for immediate management and 
to mark abnormalities. A description of the overall assessment (ie, normal or abnormal plus 
reason) will be made and a copy of the trace will be placed with the source data. 
9.6.5.
Physical and Neurological Examination 
The study investigator or other authorized and appropriately qualified designee will perform the 
physical examination at screening, Week 12, and at final follow up.
Height will be measured at screening only. Body weight will be measured at screening, Day 1, 
and at other times as specified in the Time and Events schedule.
The neurological examination can be adapted as necessary but at screening should include 
mental status (orientation and memory); oculomotor motion and vision for cranial nerve testing; 
limb strength and abnormal movements for motor function; and tests of cerebellar function: gait, 
finger-to-nose, heel-to-shin, and rapid alternating movements. Tests of sensation (eg, pain, 
vibration, etc) should be included only if indicated by clinical history/symptoms. Neurological 
examinations subsequent to screening may be more abbreviated and directed for follow up of 
abnormalities.

SUBJECT COMPLETION / WITHDRAWAL FROM THE STUDY
10.1.
Completion
A subject will be considered to have completed the study if he or she has completed the ABI at 
Week 12 (Day 85) of the double-blind phase. Subjects who prematurely discontinue study 
treatment for any reason before completion of the double-blind phase will not be considered to 
have completed the study.
10.2.
Discontinuation of Study Treatment and Withdrawal from Study
A subject's study treatment should be discontinued and the subject withdrawn from the study if:

The blind is broken at the site

The investigator believes that for safety reasons (eg, adverse event) it is in the best interest 
of the subject to discontinue study treatment

Withdrawal of consent
If a subject is lost to follow up, every reasonable effort must be made by the study site personnel 
to contact the subject and determine the reason for discontinuation/withdrawal. The measures 
taken to follow up must be documented.
When a subject withdraws before completing the study, the reason for withdrawal is to be 
documented in the CRF and in the source document. Study drug assigned to the withdrawn 
subject may not be assigned to another subject. Subjects who withdraw will not be replaced. If a 
subject withdraws from the study before the end of the double-blind treatment phase, ET/EW 
and posttreatment follow up assessments should be obtained.
If the decision to discontinue treatment or withdraw from the study is made at a study visit, that 
visit may be converted into the EW visit. The follow up visit should take place afterwards as per 
the Time and Events Schedule.
If the decision to discontinue treatment or withdraw from the study is made in-between study 
visits, the subject should return to the site as soon as possible for an EW visit. The follow up visit 
should take place afterwards as per the Time and Events Schedule.
Withdrawal from the Use of Samples in Future Research
The subject may withdraw consent for use of samples for research (refer to Section 16.2.5, 
Long-Term Retention of Samples for Additional Future Research). In such a case, samples will 
be destroyed after they are no longer needed for the clinical study. Details of the sample 
retention for research are presented in the ICF.

STATISTICAL METHODS
Statistical analyses will be conducted by the sponsor or under the authority of the sponsor. A 
general description of the statistical methods to be used to analyze the efficacy, safety, 
tolerability, PD and PK data is outlined below. Specific details will be provided in the Statistical 
Analysis Plan (SAP).
11.1.
Subject Information
The primary efficacy and safety analysis sets are defined below.

Intent-to-treat (ITT-BID): all subjects enrolled under BID dosing who receive at least 1 dose 
of study medication and have both a baseline and a postdose efficacy evaluation.

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
115
Status: Approved, Date: 29 September 2020

Safety: all randomized subjects who receive at least 1 dose of study medication
11.2.
Sample Size Determination
The sample size for the study is based on all subjects who are enrolled under BID dosing. The 
assumption used in the determination of sample size was a treatment effect size of 0.63 for the 
difference between the JNJ-42165279 treatment group and placebo, calculated as the mean 
change in the primary endpoints from baseline to Day 85. To detect the treatment effect size of 
0.63 in any of the primary endpoints with a power of 90% at an overall 1-sided significance level 
of 0.10, 25 subjects in each group are required. When adjusted for a drop-out rate of 
approximately 15% of subjects, this will require 60 subjects (under BID dosing) to be randomly 
assigned to treatment in a 1:1 ratio (30 per group).
The treatment difference effect size is based on results of a previous meta-analysis  showing that
applied behavior analytic intervention leads to medium-to-large effects on a variety of scales for 
children with autism.136 Additionally, previous studies of selective serotonin reuptake inhibitors 
(SSRIs), antipsychotics and antiepileptic drugs (AEDs) were reviewed. The sample size 
calculation is based on simulated multivariate normal data with the additional assumption that 
there is a correlation of 0.75 between the ABI Social Communication and RRB domains and 
0.90 between each of the domains and the ABI Core Domain Score.
11.3.
Efficacy Analysis
11.3.1.
Primary Efficacy Endpoints
The primary efficacy analysis will be based on the ITT-BID analysis set. The primary efficacy 
endpoints are the changes from baseline to Day 85 in the ABI Core Domain Score, ABI Social 
Communication Domain Score, and ABI RRB Domain Score during the double-blind treatment 
phase. Each will be analyzed using a mixed effects model for repeated measures (MMRM). The 
model will include time, treatment, time-by-treatment interaction, age group (13-17 years and 
18-35 years, inclusive), and gender (male and female) as factors, and baseline score as a 
continuous covariate. An unstructured variance-covariance matrix will be used. In case of 
convergence problems, simpler variance-covariance structures such as Toeplitz or autoregressive
order 1 (AR[1]) will be considered.
The study will be deemed positive if any of the primary efficacy endpoints are statistically 
superior to placebo using a 1-sided 0.10 significance level.
Additional sensitivity analyses for the primary efficacy endpoints may be specified in the SAP.
Descriptive statistics for values and changes from baseline will be provided by treatment group 
at each time point during the double-blind phase. Descriptive statistics of the primary efficacy 
endpoints may be provided by subgroups; this will be specified in the SAP.

Status: Approved, Date: 29 September 2020
11.3.2.
Secondary Efficacy Endpoints
Descriptive statistics for values and changes from baseline (where applicable) will be provided 
for all secondary efficacy measures by treatment group at each time point during the 
double-blind phase.
For the secondary efficacy endpoints, comparisons between JNJ-42165279 and placebo will be 
performed by means of an MMRM model as described for the primary efficacy endpoints.
Relationships between select biosensors and scales will be measured with the appropriate
correlation analyses. These relationships will be further defined in the SAP.
Descriptive statistics of actual values and changes from baseline (where applicable) by treatment 
group at each time point during the double-blind phase will be provided for key biosensor 
measures and standard scales.
11.4.
Biomarker and Pharmacogenomic Analysis
Baseline biomarker values (collected during screening) and changes from baseline to the time 
points specified in the Time and Events Schedule will be assessed. Biomarker values will be 
tabulated by treatment group over time points and summary statistics will be calculated. 
Associations between biomarkers and clinical endpoints will be explored. Correlations between 
values with efficacy and other clinical evaluations will be assessed.
Pharmacogenomic analyses may include candidate gene analyses or genome-wide association
analyses in relation to treatment response.
Results from biomarker and/or pharmacogenomic analyses may be presented in a separate report.
11.5.
Pharmacokinetic and Pharmacokinetic/Pharmacodynamic Analysis
An interim analysis will be conducted to evaluate the concentrations of JNJ-42165279 in plasma 
of adolescent subjects. The analysis would be performed after approximately 16 adolescent 
subjects (ie, 8 adolescent subjects randomized to active drug) have been randomized and 
participated in the PK sampling at the Week 2 visit. A procedure will be developed that 
maintains the double-blind. The interim analysis is intended to confirm that the observed JNJ-
42165279 mean concentrations in adolescent subjects fall below the upper limit of the 95% 
prediction intervals of mean JNJ-42165279 concentrations at corresponding time points 
predicted using allometric scaling.
The individual plasma JNJ-42165279 concentration-time values will be listed and summarized 
descriptively.
A population PK modeling of plasma concentrations of JNJ-42165279 will be undertaken, if 
warranted at the time of the interim analysis and after completion of the study.
CCI

Where appropriate, the relationship between plasma concentrations of JNJ-42165279 and 
corresponding plasma concentrations of 
 will be plotted to evaluate the relationships 
graphically.
Population PK/PD analysis of biomarkers and/or efficacy markers may also be performed, and a 
suitable dose- and/or exposure-response model may be developed. If necessary or relevant for 
the analysis, Phase 1 data may be integrated to inform the model structure or key parameter 
values.
Details of the PK/PD analyses, if conducted, will be described in an analysis plan and results 
may be provided in a separate report.
11.6.
Safety Analysis
All randomized subjects who receive at least 1 dose of study medication will be included in the 
safety analysis set.
Adverse Events
Adverse events will be coded using the current version of Medical Dictionary for Regulatory 
Activities (MedDRA). All reported adverse events with onset during the double-blind treatment 
phase (ie, treatment-emergent adverse events [TEAEs], and adverse events that have worsened 
since baseline) will be included in the analysis. For each TEAE, the percentage of subjects who 
experience at least 1 occurrence of the given event will be summarized by treatment group and 
dose level. Serious adverse events will be summarized separately.
Summaries, listings, datasets, or subject narratives may be provided, as appropriate, for those 
subjects who die, who withdraw due to an adverse event, or who experience a severe adverse 
event or a SAE.
Clinical Laboratory Tests
Laboratory data will be summarized by type of laboratory test. Markedly abnormal results 
(specified in the SAP) will be used in the summary of laboratory data. Descriptive statistics will 
be calculated for each laboratory analyte at baseline, and for observed values and changes from 
baseline at each scheduled time point.  
The number and percentage of subjects experiencing a laboratory result below or above
markedly abnormal ranges will be provided for each laboratory analyte by treatment group and 
dose level. 
Listings of subjects with any laboratory result outside the markedly abnormal ranges will be 
provided.
12-Lead ECG
Heart rate and ECG intervals (RR, PR, QRS and QT) as well as corrected QT intervals according 
to Fridericia’s formula (QTcF) from the 12-lead ECG will be summarized at baseline and at each

abnormal findings in ECG will be listed.
The number and percentage of subjects with QTcF value >450 msec (males only), >470 msec 
(females only), >480 msec (all subjects), or >500 msec (all subjects) will be summarized by 
treatment group, as will the number and percentage of subjects with a change from baseline in 
QTcF >30 or >60 msec.
Data listings of subjects with any potentially clinically important values (QTcF value >450
[males only], >470 [females only], >480, or >500 msec), or with a change from baseline in QTcF
>30 or >60 msec, will be provided.
Vital Signs
Descriptive statistics of pulse, blood pressure (systolic and diastolic), temperature, and body 
weight values and changes from baseline will be summarized at each scheduled time point.
The percentage of subjects with values beyond clinically important limits will be provided.
Columbia Suicide Severity Rating Scale
Suicide-related thoughts and behaviors based on the C-SSRS will be summarized by treatment 
group in incidence tables.
Aberrant Behavior Checklist-Irritability Subscale
Irritability, aggression, and self-injurious behavior based on the ABC-I will be summarized 
descriptively at each scheduled visit by treatment group.
11.7.
Data Monitoring Committee
An internal DMC, with 1 external expert, will be established to monitor data to ensure the 
continuing safety of the subjects enrolled in this study. The committee will meet at least once to 
review interim data. After the review, the DMC will make recommendations regarding the safety 
and continuation of the study. The details will be provided in a separate DMC charter.
The DMC will consist of at least 1 medical expert in the relevant therapeutic area and at least 
1 statistician. The DMC responsibilities, authorities, and procedures will be documented in its 
charter.
12.
ADVERSE EVENT REPORTING
Timely, accurate, and complete reporting and analysis of safety information from clinical studies 
are crucial for the protection of subjects, investigators, and the sponsor, and are mandated by 
regulatory agencies worldwide. The sponsor has established Standard Operating Procedures 
(SOPs) in conformity with regulatory requirements worldwide to ensure appropriate reporting of 
safety information; all clinical studies conducted by the sponsor or its affiliates will be conducted 
in accordance with those procedures.

JNJ-42165279

reviewed for clinical purposes. Participants must inform the site immediately of any medical or 
psychiatric issues.
12.1.
Definitions
12.1.1.
Adverse Event Definitions and Classifications
Adverse Event
An adverse event is any untoward medical occurrence in a clinical study subject administered a 
medicinal (investigational or non-investigational) product. An adverse event does not necessarily 
have a causal relationship with the treatment. An adverse event can therefore be any unfavorable 
and unintended sign (including an abnormal finding), symptom, or disease temporally associated 
with the use of a medicinal (investigational or non-investigational) product, whether or not 
related to that medicinal (investigational or non-investigational) product. (Definition per 
International Conference on Harmonisation [ICH]).
This includes any occurrence that is new in onset or aggravated in severity or frequency from the 
baseline condition, or abnormal results of diagnostic procedures, including laboratory test
abnormalities.
Note: The sponsor collects adverse events starting with the signing of the ICF (refer to 
Section 12.3.1, All Adverse Events, for time of last adverse event recording).
Unanticipated Study Device Effects (USDE) – UNITED STATES 
A USDE is defined as “A serious study effect on health or safety or any life-threatening problem 
or death caused by, or associated with, a device, if that effect, problem or death was not 
previously identified in nature, severity, or degree of incidence in the investigational plan or 
study brochure (including a supplementary plan or application), or any other unanticipated 
serious problem associated with a device that relates to the rights, safety or welfare of patients” 
(21 CFR 812.3[s]).
Unanticipated study device effects are considered a subset of SAEs in this study.
All study device effects will be collected per the same procedures as AEs.
Serious Adverse Event
A SAE based on ICH and EU Guidelines on Pharmacovigilance for Medicinal Products for 
Human Use is any untoward medical occurrence that at any dose:

Results in death

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.)

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
120
Status: Approved, Date: 29 September 2020

Requires inpatient hospitalization or prolongation of existing hospitalization

Results in persistent or significant disability/incapacity

Is a congenital anomaly/birth defect

Is a suspected transmission of any infectious agent via a medicinal product

Is Medically Important*
*Medical and scientific judgment should be exercised in deciding whether expedited reporting is 
also appropriate in other situations, such as important medical events that may not be 
immediately life threatening or result in death or hospitalization but may jeopardize the subject 
or may require intervention to prevent one of the other outcomes listed in the definition above. 
These should usually be considered serious.
If a serious and unexpected adverse event occurs for which there is evidence suggesting a causal 
relationship between the study drug and the event (eg, death from anaphylaxis), the event must 
be reported as a serious and unexpected suspected adverse reaction even if it is a component of 
the study endpoint (eg, all-cause mortality).
Unlisted (Unexpected) Adverse Event/Reference Safety Information
An adverse event is considered unlisted if the nature or severity is not consistent with the 
applicable product reference safety information. For JNJ-42165279, the expectedness of an 
adverse event will be determined by whether or not it is listed in the Investigator's Brochure.
Adverse Event Associated With the Use of the Drug
An adverse event is considered associated with the use of the drug if the attribution is possible, 
probable, or very likely by the definitions listed in Section 12.1.2.
12.1.2.
Attribution Definitions
Not Related
An adverse event that is not related to the use of the drug.
Doubtful
An adverse event for which an alternative explanation is more likely, eg, concomitant drug(s), 
concomitant disease(s), or the relationship in time suggests that a causal relationship is unlikely.
Possible
An adverse event that might be due to the use of the drug. An alternative explanation, 
eg, concomitant drug(s), concomitant disease(s), is inconclusive. The relationship in time is 
reasonable; therefore, the causal relationship cannot be excluded.

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
121
Status: Approved, Date: 29 September 2020
Probable
An adverse event that might be due to the use of the drug. The relationship in time is suggestive 
(eg, confirmed by dechallenge). An alternative explanation is less likely, eg, concomitant 
drug(s), concomitant disease(s).
Very Likely
An adverse event that is listed as a possible adverse reaction and cannot be reasonably explained 
by an alternative explanation, eg, concomitant drug(s), concomitant disease(s). The relationship 
in time is very suggestive (eg, it is confirmed by dechallenge and rechallenge).
12.1.3.
Severity Criteria 
An assessment of severity grade will be made using the following general categorical 
descriptors:
Mild: Awareness of symptoms that are easily tolerated, causing minimal discomfort and not 
interfering with everyday activities.
Moderate: Sufficient discomfort is present to cause interference with normal activity.
Severe: Extreme distress, causing significant impairment of functioning or incapacitation. 
Prevents normal everyday activities.
The investigator should use clinical judgment in assessing the severity of events not directly 
experienced by the subject (eg, laboratory abnormalities).
12.2.
Special Reporting Situations
Safety events of interest on a sponsor study drug that may require expedited reporting and/or 
safety evaluation include, but are not limited to:

Overdose of a sponsor study drug

Suspected abuse/misuse of a sponsor study drug

Inadvertent or accidental exposure to a sponsor study drug

Medication error involving a sponsor product (with or without subject/patient exposure to 
the sponsor study drug, eg, name confusion)

For this study, safety events of interest/adverse events of special interest include diplopia, 
vision impairment, gait disturbance, and severe headache. These events will trigger a 
neurological examination and a narrative by the investigator.
Special reporting situations should be recorded in the CRF. Any special reporting situation that 
meets the criteria of a SAE should be recorded on the SAE page of the CRF.

Procedures
12.3.1.
All Adverse Events
All adverse events and special reporting situations, whether serious or non-serious, will be 
reported from the time a signed and dated ICF is obtained until completion of the subject's last 
study-related procedure (which may include contact for follow up of safety). Serious adverse 
events, including those spontaneously reported to the investigator within 30 days after the last 
dose of study drug, must be reported using the SAE Form. The sponsor will evaluate any safety 
information that is spontaneously reported by an investigator beyond the time frame specified in 
the protocol.
All other events that meet the definition of a SAE will be reported as SAEs, regardless of 
whether they are protocol-specific assessments. Anticipated events will be recorded and reported 
as described in Attachment 15.
All adverse events, regardless of seriousness, severity, or presumed relationship to study drug, 
must be recorded using medical terminology in the source document and the CRF. Whenever 
possible, diagnoses should be given when signs and symptoms are due to a common etiology 
(eg, cough, runny nose, sneezing, sore throat, and head congestion should be reported as "upper 
respiratory infection"). Investigators must record in the CRF their opinion concerning the 
relationship of the adverse event to study therapy. All measures required for adverse event 
management must be recorded in the source document and reported according to sponsor 
instructions.
The sponsor assumes responsibility for appropriate reporting of adverse events to the regulatory 
authorities. The sponsor will also report to the investigator (and the head of the investigational 
institute where required) all suspected unexpected serious adverse reactions (SUSARs). For 
anticipated events reported as individual serious adverse events the sponsor will make a 
determination of relatedness in addition to and independent of the investigator’s assessment. The 
sponsor will periodically evaluate the accumulating data and, when there is sufficient evidence 
and the sponsor has determined there is a reasonable possibility that the intervention caused a 
serious anticipated event, they will submit a safety report in narrative format to the investigators 
(and the head of the investigational institute where required). The sponsor assumes responsibility 
for appropriate reporting of anticipated events to the regulatory authorities according to 
requirements of the countries in which the studies are conducted. The investigator (or sponsor 
where required) must report SUSARs to the appropriate Independent Ethics Committee
(IEC)/IRB that approved the protocol unless otherwise required and documented by the 
IEC/IRB. A SUSAR will be reported to regulatory authorities unblinded. Participating 
investigators and IEC/IRB will receive a blinded SUSAR summary, unless otherwise specified.
For all studies with an outpatient phase, including open-label studies, the subject must be 
provided with a "wallet (study) card" and instructed to carry this card with them for the duration 
of the study indicating the following: 

Study number

12.3.2.
Serious Adverse Events
All SAEs occurring during the study must be reported to the appropriate sponsor contact person 
by study-site personnel within 24 hours of their knowledge of the event.
Information regarding SAEs will be transmitted to the sponsor using the SAE Form, which must 
be completed and signed by a physician from the study site, and transmitted to the sponsor 
within 24 hours. The initial and follow up reports of a SAE should be made by facsimile (fax).
All SAEs that have not resolved by the end of the study, or that have not resolved upon 
discontinuation of the subject's participation in the study, must be followed until any of the 
following occurs:

The event resolves

The event stabilizes

The event returns to baseline, if a baseline value/status is available

The event can be attributed to agents other than the study drug or to factors unrelated to 
study conduct

It becomes unlikely that any additional information can be obtained (subject or health care 
practitioner refusal to provide additional information, lost to follow up after demonstration 
of due diligence with follow up efforts)
Suspected transmission of an infectious agent by a medicinal product will be reported as a SAE. 
Any event requiring hospitalization (or prolongation of hospitalization) that occurs during the 
course of a subject's participation in a study must be reported as a SAE, except hospitalizations 
for the following:

Hospitalizations not intended to treat an acute illness or adverse event (eg, social reasons 
such as pending placement in long-term care facility)

Surgery or procedure planned before entry into the study (must be documented in the CRF). 
Note: Hospitalizations that were planned before the signing of the ICF, and where the 
underlying condition for which the hospitalization was planned has not worsened, will not 
be considered SAEs. Any adverse event that results in a prolongation of the originally 
planned hospitalization is to be reported as a new SAE.

For convenience the investigator may choose to hospitalize the subject for (part of) the 
duration of the treatment period.

Status: Approved, Date: 29 September 2020
The cause of death of a subject in a study, whether or not the event is expected or associated with 
the study drug, is considered a SAE.
12.3.3.
Pregnancy
All initial reports of pregnancy in female subjects or partners of male subjects must be reported 
to the sponsor by the study-site personnel within 24 hours of their knowledge of the event using 
the appropriate pregnancy notification form. Abnormal pregnancy outcomes (eg, spontaneous 
abortion, fetal death, stillbirth, congenital anomalies, ectopic pregnancy) are considered serious 
adverse events and must be reported using the Serious Adverse Event Form. Any subject who 
becomes pregnant during the study must be promptly withdrawn from the study and discontinue 
further study intervention.
Follow-up information regarding the outcome of the pregnancy and any postnatal sequelae in the 
infant will be required.

PRODUCT QUALITY COMPLAINT HANDLING
A product quality complaint (PQC) is defined as any suspicion of a product defect related to 
manufacturing, labeling, or packaging, ie, any dissatisfaction relative to the identity, quality, 
durability, or reliability of a product, including its labeling or package integrity. A PQC may 
have an impact on the safety and efficacy of the product. Timely, accurate, and complete 
reporting and analysis of PQC information from studies are crucial for the protection of subjects, 
investigators, and the sponsor, and are mandated by regulatory agencies worldwide. The sponsor 
has established procedures in conformity with regulatory requirements worldwide to ensure 
appropriate reporting of PQC information; all studies conducted by the sponsor or its affiliates 
will be conducted in accordance with those procedures.
13.1.
Procedures
All initial PQCs must be reported to the sponsor by the study-site personnel within 24 hours after 
being made aware of the event.
If the defect is combined with a SAE, the study-site personnel must report the PQC to the 
sponsor according to the SAE reporting timelines (refer to Section 12.3.2, Serious Adverse 
Events). A sample of the suspected product should be maintained for further investigation if 
requested by the sponsor.
13.2.
Contacting Sponsor Regarding Product Quality
The names (and corresponding telephone numbers) of the individuals who should be contacted 
regarding product quality issues are listed on the Contact Information page(s), which will be 
provided as a separate document.

ETHICAL ASPECTS
16.1.
Study-Specific Design Considerations
Potential subjects will be fully informed of the risks and requirements of the study and, during 
the study, subjects will be given any new information that may affect their decision to continue 
participation. They will be told that their consent to participate in the study is voluntary and may 
be withdrawn at any time with no reason given and without penalty or loss of benefits to which 
they would otherwise be entitled. Only subjects who are fully able to understand the risks, 
benefits, and potential adverse events of the study, and provide their consent voluntarily will be 
enrolled. 
When referring to the signing of the ICF, the terms legal guardian and legally acceptable 
representative refer to the legally appointed guardian of the child with authority to authorize
participation in research. For each subject, his or her parent(s) (preferably both parents, if 
available) or legally acceptable representative(s), as required by local regulations, must give 
written consent (permission) according to local requirements after the nature of the study has 
been fully explained and before the performance of any study-related assessments. Assent must 
be obtained from children (minors) capable of understanding the nature of the study, typically 

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
128
Status: Approved, Date: 29 September 2020
subjects 7 years of age and older, depending on the institutional policies. For the purposes of this 
study, all references to subjects who have provided consent (and assent as applicable) refers to 
the subjects and his or her parent(s) or the subject's legal guardian(s) or legally acceptable
representative(s) who have provided consent according to this process. Minors who assent to a 
study and later withdraw that assent should not be maintained in the study against their will, even 
if their parent(s) still want them to participate.
The majority of subjects with ASD have normal intelligence and are expected to be able to give 
consent (adults) or assent (children). Those participants who are not competent to give consent 
should have their legally authorized representative give consent as per local regulations.
The treatment duration in this study of subjects with ASD is supported by the available 
toxicology and clinical data (see Investigator’s Brochure). A safety signal of reversible mild 
elevation of liver transaminases was identified in the Phase 1 multiple dose study, occurring in 
subjects exposed to more than 4 days dosing with 100 mg. To mitigate the risk to subjects 
participating in this trial, a dose of 25 mg BID (total daily dose of 50 mg) was selected that 
should allow for testing of the pharmacology of the compound. All subjects will be screened and 
those with evidence of pre-existing liver dysfunction will not be enrolled, clinical safety labs will 
be collected as per the Time and Events Schedule and available for ongoing monitoring by the 
investigator and sponsor, and ‘stopping rules’ have been developed for stopping treatment in the 
event that subjects have elevated liver function analytes.
A placebo arm is warranted and necessary to allow for an accurate assessment of the safety and 
tolerability of the study drug. Treatment with placebo dosing is not equivalent to non-treatment. 
All medication treatment will occur within the context of carefully supervised and supportive 
care. Only investigators experienced in the treatment of ASD will participate in the trial and can 
provide expert guidance on the alternatives for treatment if subjects elect to discontinue the study 
prior to the last visit or after the completion of the study.
Only experienced and medically-qualified study site personnel are allowed to perform safety 
assessments.
The total blood volume to be collected will not exceed 200 mL, which is considered to be safe 
and acceptable even for the youngest participants in this study in comparison to a Red Cross 
blood donation.
No treatments for ASD are required to be discontinued for this study. The inability to change or 
add new treatments during the study will not cause potential harm as there are no approved 
treatments for the core symptoms of ASD.
Females will be enrolled in this study only if they are of non-childbearing potential or agree to use 
highly effective contraception. Pregnancy testing will be performed at screening and throughout 
the study.

Regulatory Ethics Compliance
16.2.1.
Investigator Responsibilities
The investigator is responsible for ensuring that the study is performed in accordance with the 
protocol, current ICH guidelines on Good Clinical Practice (GCP), and applicable regulatory and 
country-specific requirements.
Good Clinical Practice is an international ethical and scientific quality standard for designing, 
conducting, recording, and reporting studies that involve the participation of human subjects. 
Compliance with this standard provides public assurance that the rights, safety, and well-being of 
study subjects are protected, consistent with the principles that originated in the Declaration of 
Helsinki, and that the study data are credible.
16.2.2.
Independent Ethics Committee or Institutional Review Board
Before the start of the study, the investigator (or sponsor where required) will provide the 
IEC/IRB with current and complete copies of the following documents (as required by local 
regulations):

Final protocol and, if applicable, amendments

Sponsor-approved ICF (and any other written materials to be provided to the subjects)

Investigator's Brochure (or equivalent information) and amendments/addenda

Sponsor-approved subject recruiting materials

This study will be undertaken only after the IEC/IRB has given full approval of the final 
protocol, amendments (if any, excluding the ones that are purely administrative, with no 
consequences for subjects, data or study conduct), the ICF, applicable recruiting materials, and 
subject compensation programs, and the sponsor has received a copy of this approval. This 
approval letter must be dated and must clearly identify the IEC/IRB and the documents being 
approved.
During the study the investigator (or sponsor where required) will send the following documents 
and updates to the IEC/IRB for their review and approval, where appropriate:

Protocol amendments (excluding the ones that are purely administrative, with no 
consequences for subjects, data or study conduct)

Revision(s) to ICF and any other written materials to be provided to subjects


Any other requirements of the IEC/IRB
For all protocol amendments (excluding the ones that are purely administrative, with no 
consequences for subjects, data or study conduct), the amendment and applicable ICF revisions 
must be submitted promptly to the IEC/IRB for review and approval before implementation of 
the change(s). 
At least once a year, the IEC/IRB will be asked to review and reapprove this study, where 
required. The reapproval should be documented in writing (excluding the ones that are purely 
administrative, with no consequences for subjects, data, or study conduct).
At the end of the study, the investigator (or sponsor where required) will notify the IEC about the 
study completion [(if applicable, the notification will be submitted through the head of 
investigational institution)].
16.2.3.
Informed Consent and Assent Form
Each subject (or a legally acceptable representative) must give written consent according to local 
requirements after the nature of the study has been fully explained. The ICF(s) must be signed 
before performance of any study-related activity. The ICF(s) and assent form that is/are used 
must be approved by both the sponsor and by the reviewing IEC/IRB and be in a language that 
the subject can read and understand. The informed consent should be in accordance with 
principles that originated in the Declaration of Helsinki, current ICH and GCP guidelines, 
applicable regulatory requirements, and sponsor policy.
Before enrollment in the study, the investigator or an authorized member of the study-site 
personnel must explain to potential subjects (or their legally acceptable representatives) the aims, 
methods, reasonably anticipated benefits, and potential hazards of the study, and any discomfort 
participation in the study may entail. Subjects will be informed that their participation is 

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
131
Status: Approved, Date: 29 September 2020
voluntary and that they may withdraw consent to participate at any time. They will be informed 
that choosing not to participate will not affect the care the subject will receive for the treatment 
of his or her disease. Subjects will be told that alternative treatments are available if they refuse 
to take part and that such refusal will not prejudice future treatment. Finally, they will be told 
that the investigator will maintain a subject identification register for the purposes of long-term 
follow up if needed and that their records may be accessed by health authorities and authorized 
sponsor personnel without violating the confidentiality of the subject, to the extent permitted by 
the applicable law(s) or regulations. By signing the ICF the subject (or legally acceptable 
representative), is authorizing such access, includes permission to obtain information about his or 
her survival status. It also denotes that the subject agrees to allow his or her study physician to 
recontact the subject for the purpose of obtaining consent for additional safety evaluations, and 
subsequent disease-related treatments, if needed. The physician may also recontact the subject 
for the purpose of obtaining consent to collect information about his or her survival status.
The subject (or legally acceptable representative) will be given sufficient time to read the ICF 
and the opportunity to ask questions. After this explanation and before entry into the study, 
consent should be appropriately recorded by means of either the subject's (or his or her legally 
acceptable representative's) personally dated signature. After having obtained the consent, a copy 
of the ICF must be given to the subject.
Where local regulations require, a separate ICF may be used for the required DNA component of 
the study.
If the subject (or legally acceptable representative) is unable to read or write, an impartial 
witness should be present for the entire informed consent process (which includes reading and 
explaining all written information) and should personally date and sign the ICF after the oral 
consent of the subject (or legally acceptable representative) is obtained.
Children (minors) or subjects who are unable to comprehend the information provided can be 
enrolled only after obtaining consent of a legally acceptable representative. Assent must be 
obtained from children (minors) capable of understanding the nature of the study, typically 
subjects 7 years of age and older, depending on the institutional policies. Written assent should 
be obtained from subjects who are able to write. A separate assent form written in language the 
subject can understand should be developed for adolescents. After having obtained the assent, a 
copy of the assent form must be given to the subject, and to the subject's parent or if applicable 
legally acceptable representative.
The person who will be performing the caregiver study responsibilities (parent, legally 
acceptable representative, or other) must sign a caregiver consent form indicating that he or she 
understands and is willing and able to adhere to the caregiver’s responsibilities in the study.
When prior consent of the subject is not possible (and the subject's legally acceptable 
representative is not available), enrollment procedures should be described in the protocol with 
documented approval/favorable opinion by the IEC/IRB to protect the rights, safety, and well-
being of the subject and to ensure compliance with applicable regulatory requirements. The 

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
132
Status: Approved, Date: 29 September 2020
subject (or legally acceptable representative) must be informed about the study as soon as 
possible and give consent to continue.
16.2.4.
Privacy of Personal Data
The collection and processing of personal data from subjects enrolled in this study will be 
limited to those data that are necessary to fulfill the objectives of the study.
These data must be collected and processed with adequate precautions to ensure confidentiality 
and compliance with applicable data privacy protection laws and regulations. Appropriate 
technical and organizational measures to protect the personal data against unauthorized 
disclosures or access, accidental or unlawful destruction, or accidental loss or alteration must be 
put in place. Sponsor personnel whose responsibilities require access to personal data agree to 
keep the identity of subjects confidential.
The informed consent obtained from the subject (or his or her legally acceptable representative, 
if applicable) includes explicit consent for the processing of personal data and for the 
investigator/institution to allow direct access to his or her original medical records (source 
data/documents) for study-related monitoring, audit, IEC/IRB review, and regulatory inspection. 
This consent also addresses the transfer of the data to other entities and to other countries.
The subject has the right to request through the investigator access to his or her personal data and 
the right to request rectification of any data that are not correct or complete. Reasonable steps 
will be taken to respond to such a request, taking into consideration the nature of the request, the 
conditions of the study, and the applicable laws and regulations.
Exploratory biomarker, DNA, and PK research is not conducted under standards appropriate for 
the return of data to subjects. In addition, the sponsor cannot make decisions as to the 
significance of any findings resulting from exploratory research. Therefore, exploratory research 
data will not be returned to subjects or investigators, unless required by law or local regulations. 
Privacy and confidentiality of data generated in the future on stored samples will be protected by 
the same standards applicable to all other clinical data.
16.2.5.
Long-Term Retention of Samples for Additional Future Research 
Samples collected in this study may be stored for up to 15 years (or according to local 
regulations) for additional research. Samples will only be used to understand JNJ-42165279, to 
understand ASD or other psychiatric disorders, to understand differential drug responders, and to 
develop tests/assays related to JNJ-42165279 and ASD. The research may begin at any time 
during the study or the post-study storage period. 
Stored samples will be coded throughout the sample storage and analysis process and will not be 
labeled with personal identifiers. Subjects may withdraw their consent for their samples to be 
stored for research (refer to Section 10.2, Discontinuation of Study Treatment and Withdrawal 
from Study [Withdrawal from the Use of Samples in Future Research]).

ADMINISTRATIVE REQUIREMENTS
17.1.
Protocol Amendments
Neither the investigator nor the sponsor will modify this protocol without a formal amendment 
by the sponsor. All protocol amendments must be issued by the sponsor, and signed and dated by
the investigator. Protocol amendments must not be implemented without prior IEC/IRB 
approval, or when the relevant competent authority has raised any grounds for non-acceptance, 
except when necessary to eliminate immediate hazards to the subjects, in which case the 
amendment must be promptly submitted to the IEC/IRB and relevant competent authority. 
Documentation of amendment approval by the investigator and IEC/IRB must be provided to the 
sponsor. When the change(s) involves only logistic or administrative aspects of the study, the 
IRB (and IEC where required) only needs to be notified.
During the course of the study, in situations where a departure from the protocol is unavoidable, 
the investigator or other physician in attendance will contact the appropriate sponsor 
representative (see Contact Information page(s) provided separately). Except in emergency 
situations, this contact should be made before implementing any departure from the protocol. In 
all cases, contact with the sponsor must be made as soon as possible to discuss the situation and 
agree on an appropriate course of action. The data recorded in the CRF and source documents 
will reflect any departure from the protocol, and the source documents will describe this 
departure and the circumstances requiring it.
17.2.
Regulatory Documentation
17.2.1.
Regulatory Approval/Notification

17.3.
Subject Identification, Enrollment, and Screening Logs
The investigator agrees to complete a subject identification and enrollment log to permit easy 
identification of each subject during and after the study. This document will be reviewed by the 
sponsor study-site contact for completeness.
The subject identification and enrollment log will be treated as confidential and will be filed by 
the investigator in the study file. To ensure subject confidentiality, no copy will be made. All 
reports and communications relating to the study will identify subjects by subject identification
and, if needed, month and year of birth.
The investigator must also complete a subject screening log, which reports on all subjects who 
were seen to determine eligibility for inclusion in the study.
17.4.
Source Documentation
At a minimum, source documents consistent in the type and level of detail with that commonly 
recorded at the study site as a basis for standard medical care must be available for the following: 
subject identification, eligibility, and study identification; study discussion and date of signed 
informed consent; dates of visits; results of safety and efficacy parameters as required by the 

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
135
Status: Approved, Date: 29 September 2020
protocol; record of all adverse events and follow up of adverse events; concomitant medication; 
drug receipt/dispensing/return records; study drug administration information; and date of study 
completion and reason for early discontinuation of study drug or withdrawal from the study, if 
applicable.
The author of an entry in the source documents should be identifiable.
Specific details required as source data for the study and source data collection methods will be 
reviewed with the investigator before the study and will be described in the monitoring 
guidelines (or other equivalent document).
Instruments and scales described in Section 9.2.2.6, Standard Instruments and Scales, will be 
recorded on paper forms and will be considered source data. If paper forms are used for the Daily 
Tracker, ABI, or ABI-S, the paper forms will be considered source data.
The minimum source documentation requirements for Section 4.1, Inclusion Criteria and 
Section 4.2, Exclusion Criteria that specify a need for documented medical history are as 
follows:

Referral letter from treating physician or

Complete history of medical notes at the site

Discharge summaries
Inclusion and exclusion criteria not requiring documented medical history must be verified at a 
minimum by subject interview or other protocol required assessment (eg, physical examination, 
laboratory assessment) and documented in the source documents.
An electronic source system may be utilized, which contains data traditionally maintained in a 
hospital or clinic record to document medical care (eg, electronic source documents) as well as 
the clinical study-specific data fields as determined by the protocol. This data is electronically 
extracted for use by the sponsor. If the electronic source system is utilized, references made to 
the CRF in the protocol include the electronic source system but information collected through 
the electronic source system may not be limited to that found in the CRF. Data in this system 
may be considered source documentation.
17.5.
Case Report Form Completion
Case report forms are provided for each subject in electronic format. 
Electronic Data Capture (eDC) will be used for this study. The study data will be transcribed by 
study-site personnel from the source documents onto an electronic CRF, and transmitted in a 
secure manner to the sponsor within the timeframe agreed upon between the sponsor and the 
study site. The electronic file will be considered to be the CRF.
Worksheets may be used for the capture of some data to facilitate completion of the CRF. Any 
such worksheets will become part of the subject's source documentation. Data must be entered 

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
136
Status: Approved, Date: 29 September 2020
into CRFs in English. Study site personnel must complete the CRF as soon as possible after a 
subject visit, and the forms should be available for review at the next scheduled monitoring visit.
All subjective measurements (eg, pain scale information or other questionnaires) will be 
completed by the same individual who made the initial baseline determinations whenever 
possible. The investigator must verify that all data entries in the CRFs are accurate and correct.
All CRF entries, corrections, and alterations must be made by the investigator or other authorized 
study-site personnel. If necessary, queries will be generated in the eDC tool. The investigator or 
study-site personnel must adjust the CRF (if applicable) and complete the query. 
If corrections to a CRF are needed after the initial entry into the CRF, this can be done in
3 different ways:

Study site personnel can make corrections in the eDC tool at their own initiative or as a 
response to an auto query (generated by the eDC tool).

Study site manager can generate a query for resolution by the study-site personnel.

Clinical data manager can generate a query for resolution by the study-site personnel.
17.6.
Data Quality Assurance/Quality Control
Steps to be taken to ensure the accuracy and reliability of data include the selection of qualified 
investigators and appropriate study sites, review of protocol procedures with the investigator and 
study-site personnel before the study, periodic monitoring visits by the sponsor, direct 
transmission of clinical laboratory and ECG data from a central laboratory into the sponsor's data 
base. Written instructions will be provided for collection, handling, storage, and shipment of 
samples. 
Guidelines for CRF completion will be provided and reviewed with study-site personnel before 
the start of the study. 
The sponsor will review CRFs for accuracy and completeness during on-site monitoring visits 
and after transmission to the sponsor; any discrepancies will be resolved with the investigator or 
designee, as appropriate. After upload of the data into the study database they will be verified for 
accuracy and consistency with the data sources. 
17.7.
Record Retention
In compliance with the ICH/GCP guidelines, the investigator/institution will maintain all CRFs 
and all source documents that support the data collected from each subject, as well as all study 
documents as specified in ICH/GCP Section 8, Essential Documents for the Conduct of a 
Clinical Trial, and all study documents as specified by the applicable regulatory requirement(s). 
The investigator/institution will take measures to prevent accidental or premature destruction of 
these documents.

JNJ-42165279
Clinical Protocol 42165279AUT2001 Amendment 6
137
Status: Approved, Date: 29 September 2020
Essential documents must be retained until at least 2 years after the last approval of a marketing 
application in an ICH region and until there are no pending or contemplated marketing 
applications in an ICH region or until at least 2 years have elapsed since the formal 
discontinuation of clinical development of the investigational product. These documents will be 
retained for a longer period if required by the applicable regulatory requirements or by an 
agreement with the sponsor. It is the responsibility of the sponsor to inform the 
investigator/institution as to when these documents no longer need to be retained.
If the responsible investigator retires, relocates, or for other reasons withdraws from the 
responsibility of keeping the study records, custody must be transferred to a person who will 
accept the responsibility. The sponsor must be notified in writing of the name and address of the 
new custodian. Under no circumstance shall the investigator relocate or dispose of any study 
documents before having obtained written approval from the sponsor.
If it becomes necessary for the sponsor or the appropriate regulatory authority to review any 
documentation relating to this study, the investigator/institution must permit access to such 
reports.
17.8.
Monitoring
The sponsor will perform on-site monitoring visits as frequently as necessary. The monitor will 
record dates of the visits in a study site visit log that will be kept at the study site. The first post-
initiation visit will be made as soon as possible after enrollment has begun. At these visits, the 
monitor will compare the data entered into the CRFs with the hospital or clinic records (source 
documents). The nature and location of all source documents will be identified to ensure that all 
sources of original data required to complete the CRF are known to the sponsor and study-site 
personnel and are accessible for verification by the sponsor study-site contact. If electronic 
records are maintained at the study site, the method of verification must be discussed with the 
study-site personnel. 
Direct access to source documentation (medical records) must be allowed for the purpose of 
verifying that the data recorded in the CRF are consistent with the original source data. Findings 
from this review of CRFs and source documents will be discussed with the study-site personnel. 
The sponsor expects that, during monitoring visits, the relevant study-site personnel will be 
available, the source documentation will be accessible, and a suitable environment will be 
provided for review of study-related documents. The monitor will meet with the investigator on a 
regular basis during the study to provide feedback on the study conduct.
17.9.
Study Completion/Termination
17.9.1.
Study Completion/End of Study
The study is considered completed with the last study assessment for the last subject 
participating in the study. The final data from the study site will be sent to the sponsor (or 
designee) after completion of the final subject assessment at that study site, in the time frame 
specified in the Clinical Trial Agreement.

Status: Approved, Date: 29 September 2020
17.9.2.
Study Termination
The sponsor reserves the right to close a study site or terminate the study at any time for any 
reason at the sole discretion of the sponsor. Study sites will be closed upon study completion. A 
study site is considered closed when all required documents and study supplies have been 
collected and a study-site closure visit has been performed.
The investigator may initiate study-site closure at any time, provided there is reasonable cause 
and sufficient notice is given in advance of the intended termination.
Reasons for the early closure of a study site by the sponsor or investigator may include but are 
not limited to:

Failure of the investigator to comply with the protocol, the requirements of the IEC/IRB or 
local health authorities, the sponsor's procedures, or GCP guidelines

Inadequate recruitment of subjects by the investigator

Discontinuation of further study drug development
17.10. On-Site Audits
Representatives of the sponsor's clinical quality assurance department may visit the study site at 
any time during or after completion of the study to conduct an audit of the study in compliance 
with regulatory guidelines and company policy. These audits will require access to all study 
records, including source documents, for inspection and comparison with the CRFs. Subject 
privacy must, however, be respected. The investigator and study-site personnel are responsible 
for being present and available for consultation during routinely scheduled study-site audit visits 
conducted by the sponsor or its designees. 
Similar auditing procedures may also be conducted by agents of any regulatory body, either as 
part of a national GCP compliance program or to review the results of this study in support of a 
regulatory submission. The investigator should immediately notify the sponsor if he or she has 
been contacted by a regulatory agency concerning an upcoming inspection.
17.11. Use of Information and Publication
All information, including but not limited to information regarding JNJ-42165279 or the 
sponsor's operations (eg, patent application, formulas, manufacturing processes, basic scientific 
data, prior clinical data, formulation information) supplied by the sponsor to the investigator and 
not previously published, and any data, including exploratory biomarker research data, generated 
as a result of this study, are considered confidential and remain the sole property of the sponsor. 
The investigator agrees to maintain this information in confidence and use this information only 
to accomplish this study, and will not use it for other purposes without the sponsor's prior written 
consent.
The investigator understands that the information developed in the study will be used by the 
sponsor in connection with the continued development of JNJ-42165279, and thus may be 
disclosed as required to other clinical investigators or regulatory agencies. To permit the

information derived from the clinical studies to be used, the investigator is obligated to provide 
the sponsor with all data obtained in the study.
The results of the study will be reported in a Clinical Study Report generated by the sponsor and 
will contain CRF data from all study sites that participated in the study, and direct transmission 
of clinical laboratory data from a central laboratory into the sponsor's database. Recruitment 
performance or specific expertise related to the nature and the key assessment parameters of the 
study will be used to determine a coordinating investigator. Results of pharmacogenomic or 
exploratory biomarker analyses performed after the Clinical Study Report has been issued will 
be reported in a separate report and will not require a revision of the Clinical Study Report. 
Study subject identifiers will not be used in publication of results. Any work created in 
connection with performance of the study and contained in the data that can benefit from 
copyright protection (except any publication by the investigator as provided for below) shall be 
the property of the sponsor as author and owner of copyright in such work.
Consistent with Good Publication Practices and International Committee of Medical Journal 
Editors guidelines, the sponsor shall have the right to publish such primary (multicenter) data 
and information without approval from the investigator. The investigator has the right to publish 
study site-specific data after the primary data are published. If an investigator wishes to publish 
information from the study, a copy of the manuscript must be provided to the sponsor for review 
at least 60 days before submission for publication or presentation. Expedited reviews will be 
arranged for abstracts, poster presentations, or other materials. If requested by the sponsor in 
writing, the investigator will withhold such publication for up to an additional 60 days to allow 
for filing of a patent application. In the event that issues arise regarding scientific integrity or 
regulatory compliance, the sponsor will review these issues with the investigator. The sponsor 
will not mandate modifications to scientific content and does not have the right to suppress 
information. For multicenter study designs and substudy approaches, secondary results generally 
should not be published before the primary endpoints of a study have been published. Similarly, 
investigators will recognize the integrity of a multicenter study by not submitting for publication 
data derived from the individual study site until the combined results from the completed study 
have been submitted for publication, within 12 months of the availability of the final data (tables, 
listings, graphs), or the sponsor confirms there will be no multicenter study publication. 
Authorship of publications resulting from this study will be based on the guidelines on 
authorship, such as those described in the Uniform Requirements for Manuscripts Submitted to 
Biomedical Journals, which state that the named authors must have made a significant 
contribution to the design of the study or analysis and interpretation of the data, provided critical 
review of the paper, and given final approval of the final version.
Registration of Clinical Studies and Disclosure of Results
The sponsor will register and/or disclose the existence of and the results of clinical studies as 
required by law.

ATTACHMENTS
Attachment 1: Contraceptive and Barrier Guidance and Collection of Pregnancy Information
Definitions
Woman of Childbearing Potential (WOCBP)
A woman is considered fertile following menarche and until becoming postmenopausal unless 
permanently sterile (see below).
Woman Not of Childbearing Potential

premenarchal
A premenarchal state is one in which menarche has not yet occurred.

Infertile due to medical condition
No menses for 12 months and permanently infertile due to an underlying medical condition. 
Documentation of a workup conclusively diagnostic of permanent infertility due to primary 
ovarian insufficiency will be required.

permanently sterile
Permanent sterilization methods include hysterectomy, bilateral salpingectomy, bilateral 
tubal occlusion/ligation procedures, and bilateral oophorectomy.
Note: If the childbearing potential changes after start of the study (eg, a premenarchal woman 
experiences menarche) or the risk of pregnancy changes (eg, a woman who is not heterosexually 
active becomes active), a woman must begin a highly effective method of contraception, as 
described throughout the inclusion criteria.
If reproductive status is questionable, additional evaluation should be considered.
Examples of Contraceptives
EXAMPLES OF CONTRACEPTIVESa ALLOWED DURING THE STUDY INCLUDE:
USER INDEPENDENT
Highly Effective Methods That Are User Independent Failure rate of ≤1% per year when used 
consistently and correctly.

Implantable progestogen-only hormone contraception associated with inhibition of ovulationb

Intrauterine device (IUD)

Intrauterine hormone-releasing system (IUS)

Bilateral tubal occlusion

Vasectomized partner
(Vasectomized partner is a highly effective contraceptive method provided that the partner is the 
sole sexual partner of the woman of childbearing potential and the absence of sperm has been 
confirmed. If not, additional highly effective method of contraception should be used. 
Spermatogenesis cycle is approximately 74 days.)
USER DEPENDENT
Highly Effective Methods That Are User Dependent Failure rate of <1% per year when used 
consistently and correctly.

JNJ-42165279

148
Status: Approved, Date: 29 September 2020

Combined (estrogen- and progestogen-containing) hormonal contraception associated with 
inhibition of ovulationb
oral
intravaginal
transdermal
injectables

Progestogen-only hormone contraception associated with inhibition of ovulationb
oral
injectable

Sexual abstinence
(Sexual abstinence is considered a highly effective method only if defined as refraining from 
heterosexual intercourse during the entire period of risk associated with the study intervention. 
The reliability of sexual abstinence needs to be evaluated in relation to the duration of the study 
and the preferred and usual lifestyle of the subject.)
NOT ALLOWED AS SOLE METHOD OF CONTRACEPTION DURING THE STUDY (not 
considered to be highly effective - failure rate of >1% per year)

Progestogen-only oral hormonal contraception where inhibition of ovulation is not the primary 
mode of action.

Male or female condom with or without spermicidec

Cap, diaphragm, or sponge with spermicide

A combination of male condom with either cap, diaphragm, or sponge with spermicide (double-
barrier methods)c

Periodic abstinence (calendar, symptothermal, post-ovulation methods)

Withdrawal (coitus-interruptus)

Spermicides alone

Lactational amenorrhea method (LAM)
a) Typical use failure rates may differ from those when used consistently and correctly. Use should be 
consistent with local regulations regarding the use of contraceptive methods for subjects 
participating in clinical studies.
b) Hormonal contraception may be susceptible to interaction with the study intervention, which may 
reduce the efficacy of the contraceptive method. In addition, consider if the hormonal contraception 
may interact with the study intervention.
c) Male condom and female condom should not be used together (due to risk of failure with friction).

Anticipated Events
An anticipated event is an adverse event (serious or non-serious) that commonly occurs as a 
consequence of the underlying disease or condition under investigation (disease related) or 
background regimen.
For the purposes of this study the following events will be considered anticipated events:

anxiety

depression

self-injurious behavior

disruptive/challenging behavior  
Reporting of Anticipated Events
These events will be captured on the eCRF and in the database, and will be reported to the 
sponsor as described in Section 12.3.1, All Adverse Events. 
Any event that meets SAE criteria will be reported to the sponsor within the appropriate timeline 
as described in Section 12.3.2, Serious Adverse Events. These anticipated events are exempt 
from expedited reporting as individual single cases to Health Authorities. However, if based on 
an aggregate review, it is determined that an anticipated event is possibly related to study drug, 
the sponsor will report these events in an expedited manner.

COVID-19 Appendix 
Guidance on Study Conduct during the COVID-19 Pandemic
It is recognized that the Coronavirus Disease 2019 (COVID-19) pandemic may have an impact 
on the conduct of this clinical study due to, for example, self-isolation/quarantine by participants 
and study-site personnel; travel restrictions/limited access to public places, including hospitals; 
study site personnel being reassigned to critical tasks. 
In alignment with recent health authority guidance, the sponsor is providing options for study 
related participant management in the event of disruption to the conduct of the study. This 
guidance does not supersede any local or government requirements or the clinical judgement of 
the investigator to protect the health and well-being of participants and site staff. If, at any time, 
a participant’s safety is considered to be at risk, study intervention will be discontinued, and 
study follow-up will be conducted.
Scheduled visits that cannot be conducted in person at the study site will be performed to the 
extent possible remotely/virtually or delayed until such time that on-site visits can be resumed. 
At each contact, participants will be interviewed to collect safety data. Key efficacy endpoint 
assessments should be performed if required and as feasible. Participants will also be questioned 
regarding general health status to fulfill any physical examination requirement. 
Every effort should be made to adhere to protocol-specified assessments for participants on study 
intervention, including follow up. Modifications to protocol-required assessments may be 
permitted via COVID-19 Appendix after consultation with the participant, investigator, and the 
sponsor.
The sponsor will continue to monitor the conduct and progress of the clinical study, and any 
changes will be communicated to the sites and to the health authorities according to local 
guidance.  
Modifications made to the study conduct as a result of the COVID-19 pandemic should be 
summarized in the clinical study report.

Status: Approved, Date: 29 September 2020
Continuation of Study Intervention

Any issue with continuation and/or provision of study intervention should be discussed with 
the sponsor and should be well documented.
Study Visits:

Whenever possible, subjects and caregivers should come to the clinic for their study visits in 
order to conduct assessments which can only be performed in-person (eg, select safety 
assessments, ADOS-2, KBIT-2, JAKE Task Battery, sample collection). Every study visit 
except Screening Visit 2 includes some assessments that can only be performed in-person.

Screening Visit 2 can be conducted 1) completely in-clinic, 2) completely remotely using 
telemedicine, or 3) a combination of in-clinic and remote collection via telemedicine.
Telemedicine:

Telemedicine (via phone or video conversation) conducted by qualified site personnel may 
be used for procedures that do not require in-person interaction, if needed, to reduce the 
duration of exposure between clinical staff and subjects/caregivers or if an in-clinic visit is 
not possible. Assessments that are collected by interview/questioning of subjects or 
caregivers, as well as patient- and caregiver-reported outcomes, may be collected by 
telemedicine. This can be done by using telemedicine at the clinical site (eg, in separate 
rooms) or at home. Telemedicine used within the clinic will not be considered remote data 
collection.
Laboratory Assessments:

Samples should be collected at the clinical site and shipped to a central laboratory whenever 
possible. The use of an authorized/certified local laboratory is allowed if this is not possible. 
A copy of the local laboratory report should be reviewed by the investigator and filed with 
the source documents, along with reference ranges.
Informed Consent:

Consenting and re-consenting of participants for the measures taken (including also remote 
consenting by phone or video consultation) will be performed as applicable and according to 
local guidance for informed consent applicable during the COVID-19 pandemic. The process 
is to be documented in the source documents.
Monitoring:

In case on-site monitoring visits are not possible, monitoring visits and activities may be 
conducted remotely (in accordance with site and local requirements). Additional on-site 
monitoring visits may be needed in the future to catch up on source data verification.
Site Audits:

During the COVID-19 pandemic and at the impacted sites, study site GCP audits with direct 
impact/engagement from the investigator and study site personnel may be waived in order to 
comply with national, local, and/or organizational social distancing restrictions. Additional 
quality assurance activities such as remote audits or focused review of study related 
documents may take place with limited impact/engagement if possible.

Status: Approved, Date: 29 September 2020
COVID-19-Related Documentation:

Missed assessments/visits will be captured in the clinical trial management system for 
protocol deviations. Discontinuations of study interventions and withdrawal from the study 
should be documented with the prefix “COVID-19-related” in the case report form (CRF). 
Other relevant study data elements impacted by the pandemic should also be documented/ 
labeled as “COVID-19-related” in CRFs and/or other study systems, as directed by sponsor 
guidance.
Data Analyses:

The sponsor will evaluate the totality of impact of COVID-19 on collection of key study 
data and any additional data analyses will be outlined in study SAP(s). 
Known or suspected COVID-19-positive patients:
Screening:

Patients should be excluded from study participation if they or their study-designated 
caregiver 1) are known or reported to have a positive test for COVID-19, or 2)  are 
suspected to have COVID-19 by the investigator based on symptoms, or 3) have had 
recent exposure to someone who is known to be COVID-19 positive, and have not yet 
successfully completed a period of self-isolation per local and federal guidelines.

Subjects may be eligible to rescreen at Investigator discretion provided that local and 
federal guidelines are followed for self-isolation and symptom resolution (if 
applicable) prior to the rescreening and if the subject has not already met the 
rescreening limit (only one rescreen permitted by protocol).
During Study Conduct:

If a subject has tested positive for COVID-19, the investigator should contact the 
sponsor’s responsible medical officer to discuss whether the subject can continue in the 
study and plans for study intervention and follow-up. It may be possible to continue study 
participation if the subject is asymptomatic or mildly symptomatic provided that:

current local and federal guidelines can be followed without significant impact to 
scheduled visits or procedures (including guidelines pertaining to the recommended 
self-isolation period).

the subject/caregiver can obtain the study drug from the clinic and can remain 
adherent to the restrictions outlined in Section 8.1 Prestudy and Concomitant 
Therapy.

the subject is believed to be able to resume in-clinic visits without significant visit 
delay to complete assessments that are not easily replicated by telemedicine.

the subject’s COVID-19 symptoms, if present, are judged to be unlikely to impact 
data integrity.

If the study-designated caregiver has tested positive for COVID-19, the decision whether 
to continue subject participation in the study should be discussed with the sponsor’s 
responsible medical officer.
