4.3 
Duration of Treatment 
Part I: The study will be a SAD study with subjects admitting to the clinic on Day -1, and dosing 
on Day 1, followed by a residential period that concludes on Day 4 after assessments are 
completed, except in cases where the residence is extended due to safety concerns determined by 
the Investigator in consultation with the study Medical Monitor. An EOS visit will be performed 
7 days after discharge from the in-patient unit (Day 11). The time from Screening to the EOS 
Visit is 39 days per cohort in Part I, inclusive of the Screening window. 
Part II: The study will be a cross-over, single-dose study with 2 treatment periods. Admission 
will occur on Day -1, followed by dosing (Day 1), and a washout period of at least 1 week or at 
least 5 half-lives between dosing, whichever period is longer. The duration of the washout period 
could be adapted based on the review of PK data of INDV-2000. Subjects will be discharged on 
Day 2 unless tolerability from Part I indicates a longer stay is warranted. If that is the case, 
subjects will stay in the clinical unit until Day 4. If discharged on Day 2, subjects will return to 
the clinical unit on the morning of Day 3 and Day 4 for PK testing. Depending on PK results 
from Part I, the visit schedule may be modified. An EOS visit will be performed on Day 10 of 
the last Treatment Period (Part II, Period 2). The time from Screening to the EOS Visit is 
approximately 45 days, inclusive of the Screening window.

If any of these criteria are not met, the subject will not be enrolled and randomized in Part 1, or 
will not be enrolled in Part II, Period 1 – Dosing Under Fasting Conditions, or will not be 
allowed to move forward into Part II – Dosing after High-Fat Content Meal. 
5.5 
Deviation from Inclusion/Exclusion Criteria 
This study is intended to be conducted as described in this protocol. Waivers from inclusion and 
exclusion criteria are not allowed because they have the potential to jeopardize subject safety, the 
scientific integrity of the study or regulatory acceptability of the data. Indivior does not grant 
waivers to the protocol-defined inclusion and exclusion criteria, and strict adherence to these 
criteria as outlined in the protocol is essential. The Principal Investigator (PI), sub-Investigator or 
suitably qualified designee will be responsible for identifying, documenting and reporting all 
deviations, which are defined as isolated occurrences involving a procedure that did not follow 
the study protocol or study-specific procedure. In the event of a major deviation from the 
protocol due to an emergency, accident or mistake (e. g., eligibility or dosing errors), the PI, sub-
Investigator or suitably qualified designee must contact the Indivior Medical Monitor at the 
earliest possible time by telephone. This will allow an early joint decision regarding the subject’s 
continuation in the study. This decision will be documented by the Investigator and the Sponsor. 
Deviations will be reported as required to the Institutional Review Board (IRB) per their 
reporting process and criteria, and in the final study report. 
Protocol deviations will be identified and documented through programmatic checks of study 
data, as well as through review of selected subject data listings prior to database lock.

 For a subject who discontinues due to an AE, see Section 10.1.1 for follow-up procedures. Any 
subject withdrawn or discontinuing the study after being dosed  will not be replaced. 
Subjects can be withdrawn from the study for the following reasons: 
x Pregnancy 
x Termination of the study 
x Upon the subject’s request (withdrawal of consent) 
x Significant deviation from the protocol 
x Concurrent illness or requirement for prohibited medication 
x At the discretion of the Investigator 
6.5.1 
Subject Withdrawal of Consent 
If a subject withdraws consent, the subject will not receive any additional doses of study drug in 
Part II. However, the subject may be offered additional tests as needed to monitor their safety 
(e.g., EOS safety assessments or procedures). 
6.5.2 
Subjects Lost to Follow-up 
In cases of a missed visit, the Investigator or designee must attempt to contact the subject and re-
schedule as soon as possible. The Investigator or designee must counsel the subject on the 
importance of maintaining the assigned visit schedule and ascertain whether or not the subject 
wishes to and/or should continue in the study. 
In the event a subject is lost to follow-up, the Investigator or designee must make a reasonable 
effort to contact the subject. Two documented attempts (e. g., phone, email, etc.) to contact the 
subject followed by a certified mailed letter is considered reasonable. 
For the purpose of documenting date of discontinuation for a subject confirmed to be lost to 
follow-up, the date of discontinuation should be the date of last contact with the subject. 
In the case where a certified letter is sent but not confirmed as received by the subject, the date of 
discontinuation is the date the certified letter was sent. 
In the case where a certified letter is sent and has been confirmed as received by the subject, the 
date of discontinuation is the date of the confirmed subject receipt. 
In the event that neither of these above cases applies (which should be explained in the source 
documents), the date of discontinuation is the date of the subject's last study visit.

7 STUDY SUSPENSION OR TERMINATION 
Indivior reserves the right to temporarily suspend and/or permanently discontinue the study at 
any time and for any reason, including safety or ethical concerns or severe noncompliance. If 
such action is taken, Indivior will discuss the rationale for the decision with the PI. In cases 
where a study is suspended or terminated for safety reasons, Indivior will promptly inform 
Investigators and the Regulatory Authorities of this action and the reason(s) for the suspension or 
termination. 
If required by applicable regulations, the Investigator must inform the IRB promptly and provide 
the reason(s) for the suspension or termination. If the study is prematurely discontinued, all study 
data and drug substance remaining on-site will be returned to Indivior or its designated 
representative.

No food will be allowed for at least 4 hours post-dose administration. Water is allowed as 
desired except for at least 1 hour before and at least 1 hour after drug administration. 
For the food effect evaluation of Part II, subjects will consume a high-fat meal within 30 minutes 
prior to INDV-2000 administration. The high-fat meal should provide approximately 800 to 
1000 calories, and should derive approximately 150, 250 and 500 to 600 calories from protein, 
carbohydrate and fat, respectively. Examples of an appropriate high-fat meal are provided in 
Secition 22.5, Appendix 5. Subjects should consume the entire meal in 30 minutes or less; 
however, the dose must be administered 30 minutes after the start of the meal. If the subject 
cannot complete the meal, the approximate percentage of the meal consumed should be recorded 
in the eCRF and continue with the study. Additionally, the start and finish time of the meal will 
be recorded in the eCRF. INDV-2000 will be administered with 240 mL (8 ounces) of water. No 
food will be allowed for at least 4 hours post-dose administration. Water is allowed as desired 
except for at least 1 hour before and at least 1 hour after drug administration. 
Lunch will be provided at least 4 hr post- INDV-2000 (or - placebo) dose for both parts. 
9.4 
Accountability 
The Investigator is responsible for ensuring that all drug substance and study drug is inventoried, 
accounted for and documented in accurate accountability records. Upon completion of the study 
and/or as requested by Indivior, copies of study drug and drug substance accountability records 
will be provided to Indivior. After the monitor completes reconciliation, all unused study drug 
will be destroyed by the Investigator, as per local standard operating procedures (SOP), after 
Indivior has approved the commencement of destruction. All unused drug substance and 
requested retain samples will be maintained at appropriate storage conditions and shipped 
according to the details in the Pharmacy Manual. The IMP must be handled strictly in 
accordance with the protocol, handling guidelines and the label; it must be stored in a locked, 
limited-access area under appropriate environmental conditions. 
Subject level dispensation of IMP must be documented on the appropriate subject level 
accountability form. All IMP dispensation will be performed by a pharmacist or designee, 
checked by a study site staff member and documented on a drug dispensation form. 
Used IMP bottles (for both powder in solution and capsule), and unused IMP must be available 
for verification by the site monitor during monitoring visits. 
9.5 
Reporting Product Complaints 
The Investigator and study site staff are responsible for prompt reporting of product quality 
complaints to Indivior. A product complaint is any concern pertaining to the preparation or 
quality of the drug substance or IMP, and includes, but is not limited to, broken capsules, 
labelling defects or packaging defects, IMP that is thought to be ineffective, or has an 
appearance, taste or odour that is outside of what is expected.

Subjects are required to fast a minimum of 8 hours before blood sample collection at screening. 
In accordance with the exclusion criteria, subjects will not be permitted to eat poppy seeds, 
grapefruit or Seville oranges or drink grapefruit juice or Seville orange juice within 7 days prior 
to study drug administration. 
Restrictions for water and food intake related to study drug administration are discussed in 
Section 9.3. 
9.6.3.2 
Subject Activity Restrictions 
While participating in the study, subjects will not be permitted to perform heavy exercise. 
Subjects are asked to refrain from heavy exercise starting 24 hours before IMP administration. 
9.6.3.3 
Caffeine, Alcohol and Tobacco Restrictions 
Subjects will not be permitted to drink caffeine-containing beverages, eat caffeine-containing 
foods or use caffeine-containing products prior to check-in through the EOS visit. 
In addition to 90 days prior to screening, subjects will refrain from smoking and from using e-
cigarettes and nicotine-containing products through the EOS visit. 
Subjects will refrain from drinking alcohol from prior to check-in throughthe EOS visit. 
9.7 
Compliance 
The PI or sub-Investigator may terminate a subject based on the subject’s ability to comply with 
the protocol requirements. 
 
Study drug will be administered by designated qualified study personnel at the clinical facility. 
The PI or sub-Investigator will be present during the administration of study drug. The time and 
duration, the dose delivered and any dosing observations will be recorded in source 
documentation. The PI, sub-Investigator or designated individual will maintain a log of all study 
drugs dispensed and returned. Drug supplies will be inventoried and accounted for throughout 
the study. The clinical site will have access to the Indivior Medical Monitor for any safety events 
that occur.

10 ADVERSE EVENTS 
The Investigator or designee is responsible for identifying, documenting and reporting events 
that meet the definition of an AE. 
An AE is any untoward medical occurrence in a subject associated with the use of an IMP 
regardless of the presence of a causal relationship to the IMP. An AE can be any unfavourable 
and unintended sign (including an abnormal laboratory finding) symptom or disease (new or 
exacerbated) temporally associated with an IMP, whether or not considered related to the IMP. 
x Events meeting the definition of an AE include: 
x New condition detected after IMP administration even though the AE may have been 
present prior to receiving IMP. 
x Exacerbation of a pre-existing condition (including intensification of a condition and/or 
an increase in frequency). 
x Any abnormal laboratory test results or other safety assessments felt to be clinically 
significant in the opinion of the Investigator (including those that worsen from baseline). 
x Symptoms and/or the clinical sequelae of a suspected interaction or an overdose of either 
IMP or a concomitant medication. 
x Signs, symptoms or the clinical sequelae resulting from special interest conditions (e.g., 
IMP misuse, medication error, IMP withdrawal, etc.). Overdose per se will not be 
reported as an AE/SAE. 
x Symptoms and/or clinical sequelae that resulted in intervention. 
Events that do not meet the definition of an AE include: 
x Medical or surgical procedures; the condition that leads to the procedure is an AE. 
x Situations where an untoward medical occurrence did not occur (e.g., social and/or 
convenience admission to a hospital, hospitalization for elective surgery, hospitalization 
for observation in the absence of an AE). 
x Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or 
detected at the start of the study that do not worsen. 
10.1 Assessment of Adverse Events 
The Investigator is ultimately responsible for assessing and reporting all AEs as outlined in the 
protocol. The assessment and reporting of AEs may be delegated to a medically qualified sub-
Investigator, trained on this study protocol, who is listed on the delegation of authority log. All

AEs regardless of treatment group or suspected causal relationship to the IMP will be reported as 
described in this protocol. 
Adverse events should be volunteered by the subject or solicited from the subject using a 
standard statement, obtained from examination of the subject at a site visit, or from observations 
of clinically significant laboratory values or special examination abnormal values. If an event 
assessed by one of the study scales requires intervention, or if in the opinion of the Investigator, 
it is clinically significant, then it will be reported as an AE. 
All AEs are to be assessed and recorded in a timely manner and followed to resolution or until 
the Investigator determines that there is not an anticipated resolution. Each AE is to be 
documented with reference to severity, date of occurrence, duration, treatment and outcome. 
Furthermore, each AE is to be classified as being serious or non-serious. In addition, the 
Investigator must assess whether the AE is IMP-related or not. 
10.1.1 
Time Period for Collecting Adverse Events 
Adverse event monitoring and reporting will begin after the subjects sign the ICF, continue 
throughout the study and include EOS/ET/Follow-up. Subjects will be monitored by the study 
site staff for untoward effects and will be released from the study after the last procedure is 
completed and confirmed that the subject has no residual untoward effects from the IMP that 
may affect safety. Treatment-emergent AEs will be defined events observed after starting 
administration of INDV-2000 or placebo. 
Surgical procedures, planned before enrolment of the subject in the study, are not considered 
AEs if the condition was known before study inclusion. In this case the medical condition should 
be reported in the subject’s medical history. 
Any clinically significant symptoms will be reported as AEs. All AEs and corresponding 
treatment will be recorded in the eCRFs and a summary of all the safety data will be presented in 
the final Clinical Study Report (CSR). Any ongoing AEs will be appropriately followed up until 
resolution or 14 days after EOS/ET. The study site personnel will make every effort to contact 
the subject for a minimum of 2 attempts after which the outcome of the AE will be considered 
ongoingand the subject will be noted in source as  lost to follow-up. 
If a subject experiences the onset of an SAE within 5 days following study completion and in the 
opinion of the Investigator, that SAE is associated with the study drug, it will be followed and 
reported as described in Section 11.2. 
If an SAE occurs that is deemed related to study drug, a PK sample will be taken as soon as 
possible after the event is reported. If possible, an additional sample should be collected when 
the SAE has been resolved.

10.1.2 
Assessment of Intensity 
The term “severe” is used to describe the intensity (severity) of a specific event (as in mild, 
moderate, or severe); the event itself, however, may be of relatively minor medical significance 
(such as a severe headache). This is not the same as “serious,” which is based on subject/event 
outcome or action criteria usually associated with events that pose a threat to a subject’s life or 
functioning. Seriousness (not severity) serves as a guide for defining regulatory reporting 
obligations. 
 
Intensity 
Definition 
Mild 
Causes transient or mild discomfort; no limitation of usual activities; no 
medical intervention required. 
Moderate 
Causes mild to moderate limitation in activity; some limitation of usual 
activities; no or minimal medical intervention or therapy is required.  
Severe 
Causes marked limitation in activity; some assistance is usually required; 
medical intervention or therapy is required; hospitalization is probable.  
For vital sign assessments and clinical laboraty abnormalities considered by the Investigator to 
be an Adverse Event according to Section 10.1.4, the intensitiy of adverse events will be graded 
in accordance with the FDA Guidance for Industry: Toxicity Grading Scale for Healthy Adult 
and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials (Section 22.6, 
Appendix 6). 
Adverse events with changes in severity should be documented as separate events. 
10.1.3 
Assessment of Causality 
The Investigator or a medically qualified sub-Investigator, trained on this study protocol and 
listed on the delegation of authority log is responsible for determining the AE relationship to the 
IMP. 
The following categories will be used to define the relationship of an AE to the administration of 
the IMP: 
Not Related: 
Data are available to identify a clear alternative cause for the AE other 
than the IMP.  
Related: 
The cause of the AE is related to the IMP and cannot be reasonably 
explained by other factors (e.g., the subject’s clinical state, 
concomitant therapy and/or other interventions).  
A "reasonable possibility" is meant to convey that there are facts/evidence or arguments to 
suggest a causal relationship, rather than a relationship cannot be ruled out. The Investigator will 
use clinical judgment to determine the relationship. Alternative causes, such as natural history of 
the underlying diseases, concomitant therapy, other risk factors and the temporal relationship of 
the event to the IMP will be considered and investigated. The Investigator will also consult the

IB in the determination of his/her assessment. For each AE/SAE the Investigator must document 
in the medical notes that he/she has reviewed the AE/SAE and has provided an assessment of 
causality. 
There may be situations when an SAE has occurred, and the Investigator has minimal 
information to include in the initial report to Indivior or designated representative. However, it is 
imperative that the Investigator always make an assessment of causality for every event prior to 
the initial transmission of the SAE data to Indivior or designated representative. The Investigator 
may change his/her opinion of causality in light of follow-up information and amend the SAE 
data collection tool accordingly. The causality assessment is one of the criteria used when 
determining regulatory reporting requirements. 
10.1.4 
Clinical Laboratory Changes 
Changes in laboratory values, vital signs or other safety parameters (e. g. , neurological and 
clinical symptom assessments) as noted in the protocol are a subset of AEs and are reportable 
only if the lab test result is associated with accompanying symptoms, and/ or requires additional 
diagnostic testing or intervention (medical, surgical), and/or requires additional significant 
treatment, and/or requires temporal or permanent discontinuation of IMP, or a change to dosing 
other than as permitted by protocol, or if considered to be clinically significant by Investigator or 
medically qualified designee. 
Screening laboratory assessments, if determined to be clinically significant by the Investigator, 
are not AEs.

11 SERIOUS ADVERSE EVENTS 
The Investigator or designee is responsible for identifying, documenting and reporting events 
that meet the definition of an SAE. 
An SAE is any event that meets any of the following criteria: 
x Death 
x Life-threatening 
x In-patient hospitalization or prolongation of existing hospitalization 
x Persistent or significant disability/incapacity 
x Congenital anomaly/birth defect in the offspring of a subject who received INDV-2000 
x Other: Important medical events that may not result in death, be life-threatening or 
require hospitalization, may be considered an SAE when, based upon appropriate medical 
judgment, they may jeopardize the subject and may require medical or surgical 
intervention to prevent one of the outcomes listed in this definition. Examples of such 
events are: 
 
Intensive treatment in an emergency room or at home for allergic bronchospasm 
 
Blood dyscrasias or convulsions that do not result in in-patient hospitalization 
 
Development of IMP abuse or diversion 
x Potential Hy’s Law cases indicative of medication-induced hepatocellular injury, defined 
as: 
o ALT 3x ULN and total bilirubin of 2x ULN (or INR >1. 5 if measured) 
o ALT or AST >3x ULN with systemic symptoms (fatigue, nausea, vomiting, right 
upper quadrant pain or tenderness, fever, rash and/or eosinophilia [>5%]) 
x Potential Hy’s Law cases should be managed as described in Section 22.3, Appendix 3. 
An AE is considered “life-threatening” if the subject was at immediate risk of death from the 
event as it occurred; i.e. , it does not include a reaction that if it had occurred in a more serious 
form might have caused death. For example, IMP-induced hepatitis that resolved without 
evidence of hepatic failure would not be considered life-threatening even though IMP-induced 
hepatitis can be fatal. 
AEs requiring hospitalization should be considered SAEs. Hospitalization for elective surgery or 
routine clinical procedures that are not the result of AE (e. g. , elective surgery for a pre-existing 
condition that has not worsened) should not be considered AEs or SAEs. If anything untoward is

reported during the procedure, that occurrence must be reported as an AE (either 'serious' or 
'non-serious') according to the usual criteria. 
In general, hospitalization signifies that the subject has been detained (usually involving at least 
an overnight stay) at the hospital or emergency ward for observation and/or treatment that would 
not have been appropriate in the physician's office or other outpatient setting. Complications that 
occur during hospitalization are AEs. If a complication prolongs hospitalization or fulfills any 
other serious criteria, the event is serious. When in doubt as to whether 'hospitalization' occurred 
or was necessary, the AE should be considered serious. 
An AE is incapacitating or disabling if the experience results in a substantial and/or permanent 
disruption of the subject's ability to carry out normal life functions. 
11.1 Documenting Serious Adverse Events 
When an SAE occurs, it is the responsibility of the Investigator to review all documentation 
(e.g., hospital progress notes, laboratory and diagnostic reports) pertaining to the event. The 
Investigator will then record all relevant information regarding the SAE on the appropriate 
electronic or paper form(s). 
It is not acceptable for the Investigator to send photocopies of the subject’s medical records to 
Indivior in lieu of completion of the SAE Reporting Form. However, there may be cases where 
copies of medical records are requested by Indivior or designated representative. In this instance, 
all subject identifiers, with the exception of subject number, will be redacted on the copies of the 
medical records prior to submission to Indivior. 
The Investigator will attempt to establish a diagnosis of the event based on signs, symptoms 
and/or other clinical information. In such cases, the diagnosis will be documented as an AE or 
SAE and not the individual signs/symptoms. 
11.2 Reporting Serious Adverse Events 
11.2.1 
Investigator Reporting of Serious Adverse Events 
Once the Investigator determines that an event meets the protocol definition of an SAE, the SAE 
will be reported to Indivior (or designated representative) by the Investigator (or designee) 
within 24 hours from first being aware of the event using the form provided by Indivior or 
designated representative. Any follow-up information on a previously reported SAE will also be 
reported to Indivior within 24 hours. 
Where additional information is needed or expected, the Investigator will not wait to receive all 
information before reporting the event to Indivior. The Investigator must provide an assessment 
of causality at the time of the initial report as described in Section 10.1.3. 
In the event of an SAE, the Investigator or designee will notify both the Indivior Medical 
Monitor at the phone number and/or email address listed under Study Personnel Information and

12 PREGNANCY 
Participants will include women of non-childbearing potential and men who agree to use highly 
effective means of contraception. Pregnancy is not anticipated during the conduct of this study. 
In the case where a subject’s routine pregnancy test as required per protocol is positive for 
pregnancy prior to dosing, the subject should not be dosed. If the subject has a positive urine 
pregnancy test, a confirmatory serum pregnancy test should be performed. 
12.1 Action to be Taken if Pregnancy Occurs in a Female Partner 
If the partner of a study subject becomes pregnant, the pregnancy will be reported to the clinical 
unit within 48 hours of the subject’s knowledge of the pregnancy. The Investigator will attempt 
to collect pregnancy information on any female partner of a randomized male study subject who 
becomes pregnant while participating in this study. 
After obtaining the necessary signed informed consent from the female partner directly, the 
Investigator will record pregnancy information on the appropriate form and submit it to Indivior 
or designated representative within 24 hours of learning of the partner’s pregnancy. The partner 
will also be followed to determine the outcome of the pregnancy and information on the status of 
the mother and child will be forwarded to Indivior or designated representative. Generally, 
follow-up will be no longer than 6 to 8 weeks following the estimated delivery date. Any 
premature termination of the pregnancy will be reported regardless of fetal status (presence or 
absence of anomalies) or indication for procedure.

13 DATA MANAGEMENT 
13.1 Data Collection and Management 
Data will be entered into the eCRF and will be combined with other data captured centrally 
outside of the eCRF into a validated system. Clinical data will be managed in accordance with 
the data management plan to ensure that the integrity of the data is maintained. Adverse events, 
medical history and indication for concomitant medications will be coded using the Medical 
Dictionary for Regulatory Activities (MedDRA). Concomitant medications will be coded using 
the World Health Organization (WHO) Drug Dictionary. The eCRFs (including queries and 
audit trails) will be retained by Indivior. An electronic copy of the eCRF will be sent to the 
Investigator for their records. Subject identifiers will not be collected or transmitted to Indivior 
according to Indivior standards and procedures. Data collection will be completed according to 
the study plans. 
13.1.1 
Database Quality Assurance 
The eCRFs will be reviewed and checked for omissions, apparent errors and values requiring 
further clarification using computerized and manual procedures. Data queries requiring 
clarification will be generated and addressed by the investigational site. Only authorized 
personnel will make corrections to the eCRFs, and all corrections will be documented in an audit 
trail. 
13.1.2 
Source Documents 
The Investigator is responsible for the quality of the data recorded in the eCRFs. The data 
recorded should be a complete and accurate account of the subject’s record collected during the 
study. 
Study data are not to be gathered directly onto the eCRF, but must be gathered onto primary 
source documents at the clinical site. Completion of source documents will precede the 
completion of the eCRF. Source documents may be electronic, hard copy, or a combination of 
both and are defined as the results of original observations and activities of a clinical 
investigation. Source documents will include, but are not limited to, progress notes, electronic 
data, screening logs and recorded data from automated instruments. All source documents 
pertaining to this study will be maintained by the Investigator and made available for direct 
inspection by the authorized study personnel outlined in the ICF. The CRF will be considered the 
source document for individual CRF elements such as study-specific scales if those data are 
collected directly onto a CRF.

14 STATISTICS 
14.1 General Procedures 
This section describes the sample size, analysis populations and planned analyses for PK and 
safety endpoints. A comprehensive statistical analysis plan (SAP) will be developed to detail the 
statistical methodology for all aspects of the planned analyses. The SAP will be approved after 
the protocol is finalized and before the database is locked. Any deviations from the analyses 
described below will be identified in the SAP (and subsequently the CSR). Any unplanned 
analyses not described in the SAP will be identified in the CSR. 
Data will be listed and summarized separately for Parts I and II of the study. For Part I, data will 
be summarized by dosing cohort for active treatment and for all placebo subjects combined. For 
Part II, data will be summarized by treatment group (fed or fasted) where applicable. Continuous 
variables will be summarized using descriptive statistics such as means, standard deviations 
(SD), medians, minimums and maximums. Categorical variables will be reported as frequency 
counts (including number missing) and the percentage of subjects in corresponding categories. 
Individual subject data will be presented by subject in data listings. Data listings will include all 
data collected from screened subjects (i.e., subjects who sign informed consent). 
For change from baseline calculations, baseline will be defined as the last measurement taken 
prior to dosing. 
14.2 Sample Size 
The sample size is not based on formal power calculations because the study is only designed to 
provide initial assessment of the safety, tolerability and PK for INDV-2000. The sample size 
used is typical for studies of this nature and should be adequate to assess the parameters 
described. 
14.3 Analysis Populations 
14.3.1 
Safety Population 
The Safety Population is defined as subjects who received at least one dose of IMP. 
14.3.2 
Pharmacokinetic Population 
The PK analysis population is defined as subjects who received at least one dose of INDV-2000 
and have an adequate number of PK samples collected to derive PK parameters. 
14.3.3 
Demographic and Baseline Characteristics 
Demographic and baseline characteristics (e.g., sex, race, age, weight, height, BMI) will be 
summarized for the Safety Population and separately for screen failures.

14.5 Interim Analysis 
No formal interim analysis is planned. In Part I, there will be a review of safety data for the 
sentinel group in each cohort before proceeding to the next subject in the cohort. There will also 
be a review of the safety and PK data for each cohort before dose escalation. The safety data 
review will be conducted by the DRSC (Section 15.2) using stopping rules defined in Section 
6.4. 
14.6 Handling of Missing Data 
In general, missing data (caused by premature discontinuation or otherwise) will not be imputed. 
14.7 Other Safety Analyses 
Other safety endpoints will be listed and summarized using the Safety Population. Other safety 
endpoints include changes from baseline in clinical laboratory evaluations, vital signs, ECG 
parameters and physical examinations. 
14.8 Extent of Exposure 
Frequency and percentage of subjects dosed in each cohort for Part I and dosed in each 
Fed/Fasted group separately for Part II will be provided. 
14.8.1 
Laboratory Data 
Observed values and changes from baseline in laboratory parameters will be summarized by 
analysis visit. 
Clinically abnormal laboratory results will also be summarized by frequency and percentages for 
each category. 
14.8.2 
Vital Signs 
Observed values and changes from baseline in vital signs (SBP and DBP, respiratory rate, heart 
rate and temperature) will be summarized by analysis visit. 
14.8.3 
Physical Examination 
Clinically significant physical examination findings will be summarized by analysis visit. 
14.8.4 
Electrocardiogram 
Results from 12-lead ECG will be categorized as normal, abnormal not clinically significant, or 
abnormal clinically significant and will be summarized by analysis visit using frequencies and 
percentages for each category. Observed values and changes from baseline in ECG interval 
measurements will also be summarized by analysis visit.

informed consent documents are required to have been reviewed and received a favorable 
opinion/approval from an IRB prior to presenting them to a potential subject. 
Any changes to the ICF must be reviewed by Indivior before submission to the IRB. 
The written informed consent process will include the review of oral and written information 
regarding the purpose, methods, anticipated duration and risks involved in study participation. 
The Investigator is to ensure that each subject is given the opportunity to ask questions and 
allowed time to consider the information provided. The Investigator or a person designated by 
the Investigator must also explain to each subject that participation is voluntary, and that consent 
can be withdrawn at any time and without reason. Subjects will receive a signed and dated copy 
of the signed ICF before any study-specific procedures are conducted. 
In the event that new safety information emerges that represents a significant change in the 
risk/benefit assessment, the signed ICF should be updated accordingly. All subjects should be 
informed of the new information, provide their consent to continue in the study, and be provided 
with a signed and dated copy of the revised signed ICF. 
15.5 Records Management 
The Investigator must maintain all study-related records (except for those required by local 
regulation to be maintained elsewhere) in a safe and secure location throughout the conduct and 
following the closure of the study. The records must be accessible upon request (e. g. , for an 
IRB, Indivior or regulatory inspection) along with the facility, study personnel and supporting 
systems/hardware. All documents pertaining to the study, including all versions of the approved 
study protocol, copy of the ICF and other documents as required per local laws and regulations 
(e. g. , Health Insurance Portability and Accountability Act [HIPAA] documents), completed 
CRFs, source records (subject records, subject diaries, hospital records, laboratory records, drug 
accountability records, etc. ), and other study-related materials will be retained in the permanent 
archives of the study site. 
Where permitted by local laws and regulations, records may be maintained in a format other than 
hard copy (e. g. , electronically in an electronic medical records system). The Investigator must 
ensure that all reproductions are an accurate legible copy of the original and that they meet 
necessary accessibility and retrieval standards. The Investigator must also ensure that a quality 
control process is in place for making reproductions and that the process has an acceptable back-
up of any reproductions. 
The minimum retention time for retaining study records will be in accordance with the strictest 
standard applicable for the study site as determined by local laws, regulations or institutional 
requirements. At a minimum, records will be maintained for 25 years. If the Investigator 
withdraws from the study (e. g. , relocation, retirement) all study-related records should be 
transferred, in a written agreement with Indivior, to a mutually agreed upon designee within 
Indivior-specified timeframe.

CRFs with source documents. The Investigator agrees to participate with audits conducted at a 
reasonable time in a reasonable manner. Full consultation with the Investigator will be made 
prior to and during such an audit, which will be conducted according to Indivior's or a Contract 
Research Organization's QA SOPs. In addition, this study is subject to inspections by Regulatory 
Authorities. If such a regulatory inspection occurs, the Investigator agrees to allow the regulatory 
inspector direct access to all relevant study documents. The Investigator must contact Indivior 
immediately if this occurs and must fully cooperate with the inspection conducted at a reasonable 
time in a reasonable manner.

17 AMENDMENTS 
Protocol modifications, except those intended to reduce immediate risk to study subjects, may be 
made only by Indivior. A protocol change intended to eliminate an apparent immediate hazard to 
subjects may be implemented immediately, provided the IRB is notified within 5 days. 
Any permanent change to the protocol must be handled as a protocol amendment. The written 
amendment must be submitted to the IRB and the Investigator must await approval before 
implementing the changes. Indivior or designated representative will submit protocol 
amendments to the appropriate Regulatory Authorities for approval. 
If in the judgment of the IRB, the Investigator and/or Indivior, the amendment to the protocol 
substantially changes the study design and/or increases the potential risk to the subject and/or has 
an impact on the subject's involvement as a study subject, the currently approved written ICF 
will require similar modification. In such cases, informed consent will be renewed for subjects 
enrolled in the study before continued participation, based on IRB determination.

22.3 APPENDIX 3 – Liver Safety 
 
The following should occur if a subject meets any of the liver chemistry stopping criteria as 
outlined in Section 6.4 of the protocol: 
x Subject should immediately be withdrawn from treatment. Do not re-challenge with study 
treatment. 
x Notify the Indivior Medical Monitor or specified designee within 24 hours of learning of 
the abnormality. 
x Completed the “Safety Follow-up Procedures” listed below. 
x Upon completion of the safety follow-up, the subject must be withdrawn from the study 
unless further follow-up is required. 
Subjects with ALT 3x ULN and bilirubin 2x ULN (>35% direct); or ALT 3x ULN and 
INR >1. 5: 
This event is an SAE and should be reported using the SAE Reporting Form (Section 11). 
Serum bilirubin fractionation should be performed, if testing is available. If fractionation is 
unavailable, urinary bilirubin is to be measured via dipstick (a measurement of direct bilirubin, 
which would suggest liver injury). 
Make every reasonable attempt to have the subject return to the clinic within 24 hours for repeat 
liver chemistries, additional testing and close monitoring (with specialist or hepatology 
consultation recommended). 
Monitor the subject twice weekly until liver chemistries (ALT, AST, alkaline phosphatase, 
bilirubin) resolve, stabilize or return to within baseline values. 
Subjects with ALT 5x ULN or ALT 3x ULN who have hepatitis symptoms or rash, 
cannot be monitored for 4 weeks or have elevations that persist 4 weeks: 
x Make every reasonable attempt to have the subject return to the clinic within 24-72 
hours for repeat liver chemistries and additional testing. 
x Monitor subject weekly until liver chemistries (ALT, AST, alkaline phosphatase, 
bilirubin) resolve, stabilize or return to within baseline values. 
Subjects with ALT 3x ULN and <5x ULN and bilirubin <2x ULN, who do not exhibit 
hepatitis symptoms or rash:

x Contact the Indivior Medical Monitor within 24 hours of learning of the abnormality to 
discuss subject safety. 
x Subject may continue study treatment, if liver chemistries (ALT, AST, alkaline 
phosphatase, bilirubin) can be monitored weekly for up to 4 weeks. 
x If the subject later meets the liver chemistry stopping criteria (outlined in  
Section 6.5 of the protocol), immediately withdraw study treatment, perform additional 
testing and continue safety follow-up until liver chemistries resolve, stabilize or return to 
baseline values. 
x After 4 weeks of monitoring, if ALT <3x ULN and bilirubin <2x ULN, subject must be 
monitored twice monthly until liver chemistries normalize or return to within baseline 
values. 
Additional follow-up procedures for subjects who meet any of the stopping criteria: 
x Viral hepatitis serology including: 
x Hepatitis A Immunoglobulin M (IgM) antibody, 
x HBsAg and Hepatitis B Core Antibody (IgM), 
x Hepatitis C RNA, 
x Cytomegalovirus IgM antibody, 
x Epstein-Barr viral capsid antigen IgM antibody (or if unavailable, obtain 
heterophile antibody or monospot testing), and 
x Hepatitis E IgM antibody. 
x Blood sample for PK analysis, obtained within 48 hours of last dose. 
x Serum creatine phosphokinase and lactate dehydrogenase. 
x Fractionate bilirubin, if total bilirubin 2x ULN. 
x Assess eosinophilia. 
x Record the appearance or worsening of clinical symptoms of hepatitis (fatigue, 
nausea, vomiting, right upper quadrant pain or tenderness, fever, rash or 
eosinophilia) as relevant on the AE eCRF. 
x Record use of concomitant medications, acetaminophen, herbal remedies, other 
over-the-counter medications or putative hepatotoxins on the Concomitant 
Medications eCRF.

x Record alcohol use in the eCRF. 
x In addition, the following are required for subjects with ALT 3x ULN and 
bilirubin 2x ULN (<35% direct) but optional for other abnormal liver 
chemistries: 
x Anti-nuclear antibody, anti-smooth muscle antibody, Type 1 anti-liver 
kidney microsomal antibodies and quantitative total immunoglobulin G 
(IgG or gamma globulins). 
x Serum acetaminophen adduct High-Performance Liquid Chromatography 
(HPLC) assay (quantifies potential acetaminophen contribution to livery 
injury in subjects with definite or likely acetaminophen use in the 
preceding week [ 
x James 2009]). 
x Liver imaging (ultrasound, MRI, or CT) to evaluate liver disease. Data 
should be entered into the eCRF, if these tests are performed.

FDA’s guidance documents, including this guidance, do not establish legally enforceable 
responsibilities. Instead, guidances describe FDA’s current thinking on a topic and should be 
viewed only as recommendations, unless specific regulatory or statutory requirements are cited. 
The use of the word should in FDA’s guidances means that something is suggested or 
recommended, but not required. 
 
II. 
BACKGROUND 
Standardized toxicity assessment scales have been widely used to evaluate products treating 
specific diseases. For example, the National Cancer Institute’s Common Toxicity Criteria Scale 
and the Division of AIDS’ Toxicity Grading Scale standardize the evaluation of adverse events 
among patients with cancer and HIV/AIDS, respectively (Refs. 1, 2). The defined toxicity 
parameters in those scales are designed for patients who may already experience mild, moderate, 
or severe adverse clinical or laboratory events due to the disease process, and may not be 
appropriate for healthy volunteers. 
In the development of the toxicity grading scales for healthy volunteers, we chose parameter 
limit values based on published information, when such values were available (Refs. 1-6). For 
example, the Brighton Collaboration has developed case definitions and guidelines to evaluate 
some adverse events associated with administering vaccines (Ref. 3). In some cases, parameter 
limit values were based on clinical experience and experience reviewing vaccine clinical trials 
that enroll normal healthy subjects. 
Toxicity grading scales for laboratory abnormalities should consider the local laboratory 
reference values when the parameter limit values are defined. The characterization of laboratory 
parameters among some populations of healthy adults and adolescents may require the exercise 
of clinical judgment, for example, consideration of the potential for ethnic differences in white 
blood cell (WBC) counts or gender differences in creatine phosphokinase (CPK) values. 
III. 
TOXICITY GRADING SCALE TABLES 
Adverse events in a clinical trial of an investigational vaccine must be recorded and monitored 
and, when appropriate, reported to FDA and others involved in an investigation (sponsors, IRBs, 
and investigators). (See, for example, 21 CFR 312.32, 312.33, 312.50, 312.55, 312.56, 312.60, 
312.62, 312.64, 312.66). Although the use of a toxicity grading scale for adverse events would 
not replace these regulatory requirements, using a scale to categorize adverse events observed 
during a clinical trial may assist you in monitoring safety and making required reports. 
Nonetheless, we believe that categorization or grading of data as outlined in this document is 
supplementary to and should not replace full and complete data analysis. 
These guidelines for toxicity grading scales are primarily intended for healthy adult and 
adolescent volunteers. The parameters in the tables below are not necessarily applicable to every 
clinical trial of healthy volunteers. The parameters monitored should be appropriate for the 
specific study vaccine. For some preventive vaccines under development, it may be appropriate

to include additional parameters to be monitored during a clinical trial or to alter the choice of 
values in the toxicity table. For example, additional parameters might be added based on one or 
more of the following: safety signals observed in pre-clinical toxicology studies, the biological 
plausibility of the occurrence of certain adverse events, or previous experience with a similar 
licensed product. 
As discussed above, the tables do not represent a recommendation to monitor all the listed 
parameters in all clinical trials of healthy volunteers, nor do the tables represent all possible 
parameters to be monitored. In addition, these tables do not represent study inclusion or 
exclusion criteria. We recommend that the parameters monitored be appropriate for the study 
vaccine administered to healthy volunteers participating in the clinical trial.

* The laboratory values provided in the tables serve as guidelines and are dependent upon institutional normal 
parameters. Institutional normal reference ranges should be provided to demonstrate that they are appropriate.
** The clinical signs or symptoms associated with laboratory abnormalities might result in characterization of the 
laboratory abnormalities as Potentially Life Threatening (Grade 4). For example. a low sodium value that falls 
within a grade 3 parameter (125-129 mE/L) should be recorded as a grade 4 hyponatremia event if the subject 
had a new seizure associated with the low sodium value.
***ULN” is the upper limit of the normal range.
