STUDY SUMMARY 
Protocol 
Number: 
INDV-6000-404 
Title:  
An Open-label, treatment extension study for the Rapid Initiation of 
Extended-Release Buprenorphine Subcutaneous Injection 
(SUBLOCADE™) 
Rationale:  
This study (INDV-6000-404) is to provide ongoing treatment with 
SUBLOCADE for up to 5 additional injections and safety monitoring for 
subjects who initiated SUBLOCADE following a single dose of 
transmucosal (TM) buprenorphine in study INDV-6000-403. 
Target 
Population: 
Subjects with moderate or severe opioid use disorder (OUD) who are 
seeking medication for OUD (MOUD) and have completed INDV-6000-
403 study.  
Number of 
Subjects: 
Up to 25 adult subjects 
Objective:  
The objective of this study is to assess the longer-term safety of an 
abbreviated initiation protocol of SUBLOCADE in subjects who have 
completed INDV-6000-403.  It is also to provide treatment to these 
individuals while they seek longer-term care arrangements, as it (on 
average) takes an individual with OUD 6 months between seeking treatment 
and achieving an appointment at a provider within the US.  
Study Design: 
 
Only subjects who have completed the End of Treatment (EOT) procedures 
for Study INDV-6000-403, have signed the INDV-6000-404 informed 
consent form (ICF), and meet all the enrollment criteria may be considered 
for inclusion in this study.  
 
The INDV-6000-403 EOT visit is 28 days after the subject’s first dose of 
SUBLOCADE in INDV-6000-403, therefore the INDV-6000-403 EOT and 
the INDV-6000-404 screening and Day 1 visit for this study will occur 
within 2 days, thus the INDV-6000-403 EOT assessments will serve as the 
screening assessments for the Screening Visit (Day 1) of this study.

Any AEs and concomitant medications ongoing at the INDV-6000-403 
EOT will be re-recorded for this study. In addition, demographics, height, 
medical/psychiatric, substance and drug of abuse history will not be re-
collected and will be taken from the INDV-6000-403 screening 
assessments.  A detailed detox and MOUD treatment history will be 
collected at screening. For those subjects who have enrolled in the study 
prior to approval of protocol amendment 1, their detox and MOUD 
treatment history will be collected retrospectively at their next visit. 
 
On Day 1, eligible subjects will receive a SC injection of 300mg 
SUBLOCADE. Before departing the site, any new adverse events (AEs) or 
concomitant medications will be recorded. 
 
Subjects will return to the site for monthly injection visits every 4 weeks (-2 
/ +7 days) for a total of up to 5 injections. At Injection Visits 2 through 5, 
subjects will be evaluated in accordance with local standard of care and 
results for the following procedures will be recorded: urine pregnancy test 
(to be performed before SUBLOCADE administration for all female 
subjects who are of childbearing potential); urine drug screen (UDS) and 
evaluation of previous injection site for potential reaction and evidence of 
attempts to remove the depot. For injections 2 to 5, subjects may receive 
either a dose of 100 mg SUBLOCADE or 300 mg SUBLOCADE, based on 
the medical judgment of the Investigator, per the SUBLOCADE USPI. 
During each visit the subject will be assessed for AEs and use of 
concomitant medications.  
All subjects will receive counselling as determined by local standard of care 
throughout the study from Day 1 through EOT. 
All subjects who receive SUBLOCADE (including those who wish to 
discontinue early), will be encouraged to attend the EOT/ET visit 4 weeks 
after SUBLOCADE administration.  
At the EOT/ET Visit, results for the following procedures and assessments 
will be recorded:  urine pregnancy test for all female subjects who are of 
childbearing potential; evaluation of previous injection site for potential 
reaction and evidence of attempts to remove the depot; UDS; use of 
concomitant medications and assessment for AEs. At every Visit options for 
continued care should be discussed with the subject.

Any subject with ongoing AEs or concomitant medications at the EOT Visit 
will also be followed up by telephone 4 weeks later for a safety follow up to 
assess the ongoing AEs or concomitant medications only. 
 
Primary 
Endpoint:  
The proportion of subjects with treatment emergent adverse events (TEAEs) 
at any time during the treatment period.  
Other Safety 
Assessments: 
Additional safety endpoints will include assessment of: drug-related 
TEAEs, serious TEAEs, drug-related serious TEAEs, TEAEs leading to 
treatment discontinuation and concomitant medications.

1 INTRODUCTION AND RATIONALE 
1.1 
Background 
Opioid use disorder (OUD) is a neurobehavioral syndrome characterised by repeated, 
compulsive seeking or use of an opioid despite adverse social, psychological and physical 
consequences (SAMHSA 2004). This chronic, relapsing disease has grown to epidemic 
proportions. The clinical course of OUD typically includes periods of exacerbation and 
remission, but the patient is never disease-free. Medications for OUD (MOUD) are 
recommended by treatment guidelines as the current standard of care for OUD 
(Kampman 2015), combined with counselling/behavioural therapy to provide a whole-
patient approach to the treatment of OUD.   
SUBLOCADE™ (extended-release buprenorphine) injection, for subcutaneous (SC) use 
(CIII) is an extended-release formulation of buprenorphine, a mu-opioid receptor partial 
agonist. SUBLOCADE is administered once monthly by SC injection and provides 
sustained plasma levels of buprenorphine over the dosing interval. SUBLOCADE uses 
buprenorphine and the ATRIGEL® Delivery System, which consists of a biodegradable 
polymer poly (DL-lactide-co-glycolide) with a carboxylic acid end group (PLGH), 
dissolved in a biocompatible solvent, N-methyl-2-pyrrolidone (NMP). SUBLOCADE is 
injected as a solution, and subsequent precipitation of the polymer creates a solid depot 
containing buprenorphine. After initial formation of the depot, buprenorphine is released 
via diffusion from, and the biodegradation of, the depot.  
See SUBLOCADE USPI for further information.  
1.2 
Study Rationale 
Currently, patients who are appropriate candidates for SUBLOCADE must initiate 
treatment with transmucosal (TM) buprenorphine for a minimum of 7 days before 
receiving their first injection 
(SUBLOCADE United States Prescribing Information [USPI]).  Study INDV-6000-403 
is being conducted to evaluate the safety and tolerability of starting SUBLOCADE 
treatment following a shorter period of TM buprenorphine treatment. This study (INDV-
6000-404) is to provide ongoing treatment with SUBLOCADE for up to 5 additional 
injections and safety monitoring for subjects who initiated SUBLOCADE following a 
single dose of transmucosal (TM) buprenorphine in study INDV-6000-403.  
1.2.1 
Dosing Regimen 
SUBLOCADE should be administered as per the instructions for use in the 
SUBLOCADE USPI.  
The recommended initial dose of SUBLOCADE is 300mg monthly for the first 2 
injections of treatment. Subjects have received 1 x 300mg SUBLOCADE injection in the 

16.1.1 Protocol Amendment 1 
INDV-6000-404 - SUBLOCADE Rapid Initiation Extension Study 
Confidential 
SUBLOCADE™ (extended-release buprenorphine) 
Page 15 of 52 
 
 
 
 
 
 
 
 
 
INDV-6000-403 study, therefore subjects must receive 300mg SUBLOCADE for the 
first injection of this study. Subjects may receive either 100 mg or 300 mg SUBLOCADE 
for the maintenance dose (all subsequent injections), based on the medical judgment of 
the Investigator as per the SUBLOCADE USPI.  
1.3 
Risk-Benefit Assessment  
Buprenorphine is a partial agonist at the mu-opioid receptor. As such, it produces a 
submaximal pharmacological response compared with that of a full agonist at these 
receptors and provides a greater margin of safety with respect to respiratory depression 
compared with full agonists. Buprenorphine has been shown to be an efficacious and safe 
treatment for OUD when used as directed. For this extension study, SUBLOCADE will 
be administered as recommended in the SUBLOCADE USPI.  
1.3.1 
Risk Assessment  
The safety profile of buprenorphine is well-established, and the AE profile of 
buprenorphine is well characterised. Commonly reported treatment-emergent AEs 
include drug withdrawal syndrome, constipation, headache, nausea and vomiting. 
Buprenorphine has been approved for multiple indications and routes of administration 
(e.g., TM, buccal, intramuscular, intravenous, transdermal, rectal and subcutaneous) in 
multiple countries and by various manufacturers. Buprenorphine extended-release SC 
injection was approved as a monthly treatment for OUD in 2017 (SUBLOCADE USPI).   
The most common adverse drug reactions with SUBLOCADE were constipation, nausea, 
hepatic enzyme increased, headache, injection site pain, injection site pruritus, vomiting 
and fatigue. Injection site reactions were generally mild to moderate in severity, none 
were serious, and they decreased in frequency with subsequent injections. There were no 
unexpected safety findings. The safety profile of SUBLOCADE observed in the Phase III 
studies was generally consistent with the known safety profile of buprenorphine, with the 
expected exception of injection site tolerability and reaction.  
1.3.2 
Benefit Assessment  
Clear efficacy was demonstrated both in the pivotal and in additional supporting studies 
of the SUBLOCADE clinical development programme (SUBLOCADE USPI). While 
subjects will receive limited benefit from participation in the single-dose (of 
SUBLOCADE) study (INDV-6000-403), participation in the combined INDV-6000-403 
and INDV-6000-404 studies will allow more meaningful engagement with MOUD and 
the results could provide support for more rapid SUBLOCADE initiation, which is 
expected to improve treatment compliance, engagement and retention in treatment.  With 
increasing amounts of fentanyl contamination of the heroin drug supply, it is also 
important to treat patients with a medicine that can protect them from overdose as soon as 
they are willing to engage in treatment.  Recently reported data (Wiest 2019) supports 
that buprenorphine, administered at doses resulting in consistent plasma levels of 2ng/mL

and 5ng/mL (similar to the concentrations resulting from both labelled doses of 
SUBLOCADE), is able to dose dependently inhibit fentanyl-induced respiratory 
depression.  Being able to initiate treatment-seeking patients with SUBLOCADE on the 
1st day of treatment may therefore help to protect patients when they are most vulnerable.  
1.3.3 
Overall Risk-Benefit Summary  
Taken together, these findings indicate a favourable benefit/risk assessment for this 
extension of the single dose study (INDV-6000-403) to evaluate a more rapid treatment 
initiation protocol for SUBLOCADE in patients with OUD.

2 STUDY OBJECTIVE 
The objective of this study is to assess the longer-term safety of an abbreviated initiation 
protocol of SUBLOCADE in subjects who have completed INDV-6000-403.  It is also to 
provide treatment to these individuals while they seek longer-term care arrangements, as 
it (on average) takes an individual with OUD 6 months between seeking treatment and 
achieving an appointment at a provider within the US.

4 STUDY PLAN 
4.1 
Study Design 
 
This is a single center, open-label, SUBLOCADE treatment extension study in which up 
to 25 subjects diagnosed with moderate or severe OUD will be enrolled. A subject is 
defined as enrolled when the first dose of SUBLOCADE is administered for this study.  
Only subjects who have completed the End of Treatment (EOT) procedures for Study 
INDV-6000-403, have signed the INDV-6000-404 informed consent form (ICF), and 
meet all the enrollment criteria may be considered for inclusion in this study.  
The INDV-6000-403 EOT visit is 28 days after the subjects first dose of SUBLOCADE 
in INDV-6000-403, therefore the INDV-6000-403 EOT and the INDV-6000-404 
screening and Day 1 visit for this study will occur within 2 days.  
The ICF may be shared with the potential subject before the INDV-6000-403 EOT Visit 
to discuss this study as a possible treatment option. However, the ICF must not be signed 
until all assessments for the INDV-6000-403 EOT Visit are complete. 
 
The INDV-6000-403 EOT assessments will serve as the screening assessments for the 
Screening Visit (Day 1) of this study. Any AEs and concomitant medications ongoing at 
the INDV-6000-403 EOT will be re-recorded for this study. In addition, demographics, 
height, medical/psychiatric, substance and drug of abuse history will not be re-collected 
and will be taken from the INDV-6000-403 screening assessments. A detailed detox and 
MOUD treatment history will be collected at screening. For those subjects who have 
enrolled in the study prior to approval of protocol amendment 1, their detox and MOUD 
treatment history will be collected retrospectively at their next visit. 
 
On Day 1, eligible subjects will receive a SC injection of 300mg SUBLOCADE.  
Before departing the site, any new adverse events (AEs) or concomitant medications will 
be recorded. 
 
Subjects will return to the site for monthly injection visits every 4 weeks (-2 / +7 days) 
for a total of up to 5 injections. At Injection Visits 2 through 5, subjects will be evaluated 
in accordance with local standard of care and results for the following procedures will be 
recorded: urine pregnancy test (to be performed before SUBLOCADE administration for 
all female subjects who are of childbearing potential); urine drug screen (UDS) and 
evaluation of previous injection site for potential reaction and evidence of attempts to 
remove the depot. For injections 2 to 5, subjects may receive either a dose of 100 mg 
SUBLOCADE or 300 mg SUBLOCADE, based on the medical judgment of the 
Investigator, per the SUBLOCADE USPI. During each visit the subject will be assessed 
for AEs and use of concomitant medications.

All subjects will receive counselling as determined by local standard of care throughout 
the study from Day 1 through EOT. 
All subjects who receive SUBLOCADE (including those who wish to discontinue early), 
will be encouraged to attend the EOT/ET visit 4 weeks after SUBLOCADE 
administration.  
At the EOT/ET Visit, results for the following procedures and assessments will be 
recorded:  urine pregnancy test for all female subjects who are of childbearing potential; 
evaluation of previous injection site for potential reaction and evidence of attempts to 
remove the depot; UDS; use of concomitant medications and assessment for AEs. At 
every Visit options for continued care should be discussed with the subject. 
Any subject with ongoing AEs or concomitant medications at the EOT Visit will also be 
followed up by telephone 4 weeks later for a safety follow up to assess the ongoing AEs 
or concomitant medications only. 
4.2 
Schedule of Assessments 
An overview of the schedule of assessments for the study is provided in Table 1.

5 POPULATION 
5.1 
Number of Subjects 
Up to 25 adult subjects with moderate or severe OUD who are seeking MOUD and have 
completed the EOT Visit for the INDV-6000-403 study are planned to be enrolled into 
the study.  
5.2 
Inclusion Criteria 
Subjects must meet all the following criteria to be eligible for the study:  
1. Signed the informed consent form (ICF) and have the ability to comply with the 
requirements and restrictions listed therein.  
2. Completed the EOT Visit for the INDV-6000-403 Study.  
3. Is an appropriate candidate in the opinion of the Investigator or medically qualified 
sub-Investigator. 
5.3 
Exclusion Criteria 
Subjects who meet any of the following criteria will be excluded from the study: 
1. Subject compliance issues during participation in the INDV-6000-403 study which, 
in the opinion of the Investigator, could potentially compromise subject safety. 
2. Subjects who are unable, in the opinion of the Investigator or Indivior, to comply 
fully with the study requirements including those who are currently incarcerated or 
pending incarceration/legal action. 
5.4 
Subject Screening 
Subjects who provide written informed consent will have their INDV-6000-403 
assessments (per Table 1) re-reviewed to confirm study eligibility. 
5.5 
Deviation from Inclusion/Exclusion Criteria 
Waivers from inclusion and exclusion criteria are not allowed because they have the 
potential to jeopardise 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.

6 STUDY CONDUCT 
6.1 
Subject Screening 
Study screening begins once written informed consent is obtained; the same subject 
identification number from INDV-6000-403 will be assigned. The subject identification 
number will be used to identify the subject during the screening process and throughout 
study participation, if applicable.  
The Investigator is responsible for maintaining a master list (i.e., a subject identification 
list) of all consented subjects and will document all subjects that do not meet study 
eligibility criteria (i.e., screen failures), including reason(s) for ineligibility (i.e., a subject 
screening and enrolment log). This document will be reviewed by Indivior or designated 
representative for accuracy and completeness. Ineligible subjects, as defined by the 
protocol-specific inclusion and exclusion criteria, should not receive study drug and 
should be documented as screen failures.   
6.2 
Enrolled 
A subject will be considered enrolled if he/she receives at least 1 dose of SUBLOCADE. 
6.3 
Not Enrolled 
A subject will be considered not enrolled if written informed consent is obtained but the 
subject does not receive SUBLOCADE. Reasons for not enrolling (e.g., withdrawal of 
consent, does/not meet specified inclusion or exclusion criteria) will be recorded in the 
case report form (CRF).  
6.4 
Treatment Period 
Treatment period begins when the SUBLOCADE injection is given on Day 1 and ends 
after all assessments have been made at the EOT Visit.  
6.5 
Treatment Period Completion  
A subject will be considered as completing the treatment period if they have received 
Injection 1 and Injection 5.   
6.6 
Study Completion  
A subject will be considered to have completed the study if they have completed the last 
injection visit (Injection 5) and the scheduled EOT visit.

Confidential 
SUBLOCADE™ (extended-release buprenorphine) 
Page 25 of 52 
 
 
 
 
 
 
6.7 
Early Termination  
A subject will be considered an Early Termination if he/she is dosed with SUBLOCADE 
and does not complete the study (did not complete the last injection visit [Injection 5]) 
and the scheduled EOT visit.  
Reasons for early termination (e.g., withdrawal of consent, lost to follow up, 
identification / move to alternative treatment site) will be recorded in the CRF. Subjects 
who Early Terminate from the study will be encouraged to attend the ET visit 4 weeks 
after SUBLOCADE administration, as well as a safety follow up via telephone if any 
AEs and concomitant medications are ongoing at the time of the ET visit.  
6.8 
Withdrawal and Stopping Criteria   
6.8.1 
Subject Withdrawal from the Study  
If the subject has discontinued study treatment (including depot removal) and is no longer 
being followed for study assessments and procedures (including follow-up procedures), 
he/she will be considered withdrawn from the study. The primary reason for withdrawing 
from the study must be entered into the CRF (e.g., subject is lost to follow-up, Indivior 
terminates the study or Investigator’s discretion).   
6.8.2 
Subject Withdrawal of Consent  
If a subject withdraws consent, the subject will not receive any additional doses of study 
drug. However, the subject may be offered additional tests as needed to monitor safety 
(e.g., EOT safety assessments or procedures).  
6.8.3 
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., telephone, 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.

Confidential 
SUBLOCADE™ (extended-release buprenorphine) 
Page 26 of 52 
 
 
 
 
 
 
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 non-
compliance. If such action is taken, Indivior will discuss the rationale for the decision 
with the Investigator. 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 Institutional 
Review Board (IRB) promptly and provide the reason(s) for the suspension or 
termination. If the study is prematurely discontinued, all study data and study drug 
remaining at the clinic must be returned to Indivior or its designated representative.  
8 DESCRIPTION OF STUDY PROCEDURES 
Study subjects will be evaluated in accordance with local standard of care, and only 
results for study specific assessments and procedures will be recorded in the CRF. Study 
assessments and procedures, including the timing of assessments, are summarised in 
Table 1. Further details on safety assessments are provided in Section 8.2.  
A signed written ICF must be obtained from the subject before any study assessments or 
procedures may be performed. All assessments and procedures may be performed more 
frequently, if clinically indicated.  
8.1 
Demographics and Medical/Psychiatric History 
A detailed medical and psychiatric history was collected during the INDV-6000-403 
study and will not be re-collected. A detailed detox and MOUD treatment history will be 
collected at screening. For those subjects who have enrolled in the study prior to approval 
of protocol amendment 1, their detox and MOUD treatment history will be collected 
retrospectively at their next visit. 
8.2 
Safety Assessments 
Definitions and procedures for reporting AEs and SAEs are provided in Sections 10 and 
11, respectively. 
8.2.1 
Clinical Laboratory Tests  
Clinical laboratory tests for Virology, Haematology, Serum Chemistry and Urinalysis 
were collected during the INDV-6000-403 study and will not be re-collected.

 Phencyclidine 
Additional information related to the collection and handling of urine specimens is 
located in the laboratory manual.  
8.2.1.2 
Urine Pregnancy Test 
A urine pregnancy test will be performed at each visit using a licensed test (dipstick), for 
females of child bearing potential only.  
Additional information related to the collection and handling of urine specimens is 
located in the laboratory manual.  
8.2.2 
Injection site Evaluation  
The Injection site will be evaluated for signs of attempted removal before dosing with 
SUBLOCADE at each visit, as shown in Table 1. Any attempts at a SUBLOCADE depot 
removals by the subject should be reported as an AE, and any removals should be 
reported as an AE of Special Interest, see Section 10.7. Any injection site reactions or 
infections will be recorded as AEs. 
8.3 
Protocol Deviations 
A protocol deviation is any non-compliance with the clinical study protocol or ICH/GCP 
requirements. The non-compliance may be on the part of the subject, the Investigator or 
the study clinic staff. As a result of deviations, corrective actions are to be developed by 
the clinic and implemented promptly and in accordance with ICH E6. It is the 
responsibility of the Investigator and study clinic staff to use continuous vigilance to 
identify and report deviations to Indivior or specified designee and the IRB. All 
deviations must be reported in the study source documents. Protocol deviations must be

sent to the IRB as required. The Investigator and study clinic staff are responsible for 
knowing and adhering to the IRB’s requirements. 
9 STUDY DRUG MANAGEMENT 
The study drug, SUBLOCADE, will be provided by the Sponsor in two strengths 100mg 
and 300mg buprenorphine.  
9.1 
Description 
9.1.1 
Formulation  
SUBLOCADE is a colourless to amber sterile solution for SC injection designed to 
deliver a buprenorphine dose at a controlled rate over a 1-month period. The active 
ingredient in SUBLOCADE is buprenorphine (free base), a mu-opioid receptor partial 
agonist and a kappa-opioid receptor antagonist. Buprenorphine is dissolved in the 
ATRIGEL delivery system at 18% by weight and is a biodegradable 50:50 poly (DL-
lactide-co-glycolide) polymer and a biocompatible solvent, N-methyl-2-pyrrolidone.  
Adequate precautions must be taken to avoid direct contact with the study drug. 
Occupational hazards and recommended handling procedures are provided in the Safety 
Data Sheet.  
9.1.2 
Storage 
SUBLOCADE must be stored in a refrigerator at 2° to 8°C (35.6° to 46.4°F) in 
accordance with the USPI, in a secure location with limited access. Once outside the 
refrigerator, SUBLOCADE may be stored in its unopened original packaging at room 
temperature, 15°C to 30°C (59°F to 86°F), for up to 7 days prior to administration. 
Discard SUBLOCADE if left at room temperature for longer than 7 days. 
Temperature excursions outside of the defined ranges should be reported to the Sponsor, 
the product should be immediately quarantined and only used if/after Sponsor approval 
has been obtained (see Pharmacy Manual).  
The study drugs must be handled strictly in accordance with the protocol, USPI, 
Pharmacy Manual and applicable local laws and regulations. 
9.2 
Packaging and Labelling 
The SUBLOCADE clinical study labels will be developed in accordance with Good 
Manufacturing Practice (GMP) and local regulatory requirements. Detailed information 
regarding the commercial packaging of SUBLOCADE is outlined in the USPI.  
SUBLOCADE inner packaging (pouch) must remain with the outer product carton until 
the time of administration.

9.3 
Shipment 
SUBLOCADE will be shipped under monitored refrigerated temperatures between 2ºC to 
8ºC (35.6°F to 46.4°F).  
9.4 
Dose and Administration 
SUBLOCADE will be supplied by the Sponsor as a single, pre-filled syringe, the entire 
contents of which should be administered during a single SC injection by a licensed 
healthcare provider as delegated by the Investigator.  
SUBLOCADE should be administered as per the instructions for use in the 
SUBLOCADE USPI. The recommended initial dose of SUBLOCADE is 300mg monthly 
for the first 2 injections of treatment. Subjects have received 1 x 300mg SUBLOCADE 
injection in the INDV-6000-403 study, therefore subjects must receive 300mg 
SUBLOCADE for the first injection of this study.  
Subjects may receive either 100 mg or 300 mg SUBLOCADE for the maintenance dose 
(all subsequent injections), based on the medical judgment of the Investigator as per the 
SUBLOCADE USPI. Reasons for dose adjustments should be recorded in the source and 
CRF.  
Time of dose for SUBLOCADE is defined as the time the SC injection is complete. The 
time of dose and any dosing observations (e.g., partial doses or other issues with the 
injection) will be recorded in the source documentation; in addition, time of dose will be 
recorded in the CRF.  
The Investigator will not supply SUBLOCADE to any person except study personnel for 
SC injection of subjects in this study.  SUBLOCADE will be dispensed under the 
supervision of the Investigator, a suitably qualified member of the study team, or by a 
pharmacist. The Investigator or designee agrees to neither administer SUBLOCADE 
from, nor store it at any location other than the study clinic agreed upon with the Sponsor. 
Clinic personnel must maintain accountability records per the Pharmacy Manual.  
9.5 
Accountability 
The Investigator is responsible for ensuring that all study drug received at the clinic is 
inventoried, accounted for and documented in accurate accountability records.  
Accountability records will be provided to Indivior. All unused study drug will be 
destroyed by the Investigator, as per local standard operating procedures (SOP). The 
study drug must be handled strictly in accordance with the protocol, handling guidelines 
and the USPI; it must be stored in a locked, limited-access area under appropriate 
environmental conditions.   
The dispensing of study drug to the subject must be documented on the drug dispensing 
form. All study drug dispensation will be performed by a pharmacist or designee, 
checked by a study centre staff member and documented on a drug dispensation form.

Unused study drug must be available for verification by the monitor during on-site 
monitoring visits.   
9.6 
Concomitant Therapies 
Concomitant medications will be collected from screening (including ongoing 
concomitant medications recorded at the INDV-6000-403 EOT) until the INDV-6000-
404 EOT at the time points listed in Table 1. Any subject with ongoing concomitant 
medications at the INDV-6000-404 EOT will be followed up by telephone 4 weeks later 
for a safety follow up to assess the ongoing concomitant medications.  
Any concomitant medications (including herbal preparations) taken during the study will 
be recorded in the source documents and in the CRF. Any changes in concomitant 
therapy during the study will be documented, including cessation of therapy, initiation of 
therapy and dose changes. 
9.7 
Prohibited Concomitant Therapies 
Subjects should be instructed not to take any medications, including over-the-counter 
products, without first discussing with the Investigator.   
Supplemental TM buprenorphine (after SUBLOCADE injection) may only be permitted 
after discussions with the medical monitor.   
Due to additive pharmacologic effects, the concomitant use of benzodiazepines or other 
CNS depressants, including alcohol, increases the risk of respiratory depression, 
profound sedation, coma and death.  
The SUBLOCADE USPI should be referenced regarding use of the below concomitant 
therapies.  
benzodiazepines and other CNS depressants 
cytochrome P450 3A4 inhibitors or inducers (see Appendix 1) 
antiretrovirals: non-nucleoside reverse transcriptase inhibitors (NNRTIs) 
antiretrovirals: protease inhibitors 
serotonergic drugs 
monoamine oxidase inhibitors (MAOIs) 
muscle relaxants 
diuretics 
anticholinergic drugs 
The Indivior medical monitor should be notified if a subject receives any of these 
treatments during the study.

9.8 
Lifestyle Restrictions 
Eligible subjects will be advised to abstain from alcohol  throughout the study, as central 
nervous system depressants increase the risk of respiratory depression, profound sedation, 
coma and death in patients taking buprenorphine (SUBLOCADE USPI). 
9.9 
Permitted Concomitant Therapies 
The Investigator may prescribe concomitant medications or treatments deemed necessary 
to the subject, except those medications defined in Section 9.7 of this protocol. 
If the subject experiences withdrawal symptoms at any time, he/she may be treated 
symptomatically (SAMHSA TIP 63 2018): 
Nausea: ondansetron or metoclopramide 
Diarrhoea: loperamide 
Anxiety, irritability, sweating: clonidine 
Insomnia: diphenhydramine, trazodone 
Pain: nonsteroidal anti-inflammatory drugs 
Supplemental buprenorphine may only be permitted after discussions with the medical 
monitor. Subjects will not be discontinued from treatment due to illicit opioid use 
(including buprenorphine). 
9.10 
Compliance 
All study drugs will be administered in the clinic and documented in the source and 
recorded in the CRF.  
SUBLOCADE compliance will be assessed by inspecting the injection site for evidence 
of attempted removal of the depot by the subject, documented in the source and recorded 
in the CRF. Likewise, surgical removal by a physician will be documented in the source 
and recorded in the CRF. See Section 10.7 for details on reporting depot removal. 
Use of prohibited concomitant medications will be evaluated per the Concomitant 
Medication assessment outlined in the Table 1, documented in the source and recorded in 
the CRF. 
9.11 
Reporting Product Complaints  
The Investigator and study clinic staff are responsible for prompt recognition and 
reporting of product quality complaints to Indivior. A product complaint is any concern 
pertaining to the manufacturing or quality control of the study drug and includes, but is 
not limited to, e.g., short counts/empty pouches, leaking syringes, broken needles, 
labelling defects, missing inserts, packaging defects or difficult to open packaging, study 
drug that is thought to be ineffective, or has an appearance or odour that is outside of 
what is expected.

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 a study 
drug regardless of the presence of a causal relationship to the study drug. An AE can be 
any unfavourable and unintended sign (including an abnormal laboratory finding) 
symptom or disease (new or exacerbated) temporally associated with a study drug, 
whether or not considered related to the study drug.  
 Events meeting the definition of an AE include:  
 New condition detected after study drug administration even though the AE may 
have been present prior to receiving study drug.  
 Exacerbation of a pre-existing condition (including intensification of a condition 
and/or an increase in frequency).  
 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).   
 Symptoms and/or the clinical sequelae of a suspected interaction or an overdose 
of either study drug or a concomitant medication.  
 Signs, symptoms or the clinical sequelae resulting from special interest conditions 
(e.g., medication error, SUBLOCADE depot removal, etc.).  
 Symptoms and/or clinical sequelae resulting from lack of efficacy will be reported 
if they fulfil the definition of an AE.  
 Symptoms and/or clinical sequelae that resulted in intervention.  
 Evidence of a subject attempting removal of the SUBLOCADE depot  
Events that do not meet the definition of an AE include:  
 Medical or surgical procedures; the condition that leads to the procedure is an AE.  
 Situations where an untoward medical occurrence did not occur (e.g., social 
and/or convenience admission to a hospital, hospitalisation for elective surgery, 
hospitalisation for observation in the absence of an AE).  
 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 
AEs of Special Interest 
In this study, an AE of special interest is any occurrence of a SUBLOCADE depot 
removal (see Section 10.7); Subjects with alanine aminotransferase (ALT) ≥3 × upper 
limit of normal (ULN) and bilirubin ≥2 × ULN (> 35% direct) are defined as SAEs of 
special interest.  
This AE of special interest should be reported to Indivior, by the Investigator (or 
designee) within 24 hours from first being aware of the event, using the same reporting 
process as for SAEs, see Section 11.2. 
10.2 
Assessing and Documenting 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 suspected causal relationship to the study drug 
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 clinic visit, or from 
observations of clinically significant laboratory values or special examination abnormal 
values.  
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 study drug-related or not. 
10.3 
Time Period for Collecting Adverse Events 
Adverse events will be collected from the time of signed informed consent (including 
ongoing AEs at the INDV-6000-403 EOT) until completion of the EOT visit. Any subject 
with ongoing AEs at the INDV-6000-404 EOT will be followed up by telephone 4 weeks 
later for a safety follow up to assess the ongoing AEs. 
Subjects with ongoing SAEs at the safety follow up telephone contact that, in the opinion 
of the Investigator, are associated with the study drug, will be followed and reported as 
described in Section 11. Subjects with ongoing AEs at safety follow up telephone contact 
that, in the opinion of the Investigator, are associated with the study drug, will be 
followed and reported as described in Section 10.2. 
10.4 
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 

16.1.1 Protocol Amendment 1 
INDV-6000-404 - SUBLOCADE Rapid Initiation Extension Study 
Confidential 
SUBLOCADE™ (extended-release buprenorphine)

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; hospitalisation is probable    
Adverse events with changes in severity should be documented as separate events. 
10.5 
Assessment of Causality 
The Investigator or a medically qualified sub-Investigator, trained on this study protocol, 
listed on the delegation of authority log is responsible for determining the AE 
relationship to the study drug.  
The following categories will be used to define the relationship of an AE to the 
administration of the study drug:  
Not Related: Data are available to identify a clear alternative cause for the AE other 
than the study drug.  
 Related:  
The cause of the AE is related to the study drug 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 that 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 study drug will be considered and 
investigated. The Investigator will also consult the USPI 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 or AE of special interest 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 or AE 
of special interest 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 
or AE of special interest data collection tool accordingly. The causality assessment is one 
of the criteria used when determining regulatory reporting requirements. 
10.6 
Clinical Laboratory Changes 
Clinical Laboratories are not collected for this study. However, if an Investigator 
performs these tests as part of the local standard of care the results may be considered a 
reportable AE 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 study drug, or a change to dosing other than as permitted by protocol.   
If a subject experiences any of the below Liver Chemistry criteria the Indivior medical 
monitor should be notified to discuss the subject’s course of action: 
1. The subject has ALT >3 × ULN and bilirubin >2 × ULN (˃35% direct bilirubin). 
2. The subject has ALT >3 × ULN and associated with symptoms (new or 
worsening) believed to be related to hepatitis (such as fatigue, nausea, vomiting, 
right upper quadrant pain or tenderness, or jaundice) or hypersensitivity (such as 
fever, rash or eosinophilia). 
3. The subject has ALT >5 × ULN but <8 × ULN persisting for >2 weeks. 
4. The subject has ALT >5 × ULN but <8 × ULN and cannot be monitored weekly 
for ≥2 weeks.  
5. The subject has ALT >8 × ULN. 
If the subject experiences Criterion 1, this is an SAE (important medical event) of special 
interest, that must be reported to Indivior as per Section 11.2.1.  
10.7 
SUBLOCADE Depot Removal 
If clinically indicated, the SUBLOCADE depot may be surgically removed within 
14 days of injection. Any occurrence of depot removal will be captured in the database as 
an AE of special interest. In addition, the AE that resulted in the depot removal needs to 
be reported; this is not an AE of special interest. Additional details about the depot 
removal (e.g., whether the depot was removed by the subject or the Investigator and 
whether this was voluntary or involuntary [i.e., whether the subject agreed to the 
removal]) also need to be reported. Depot removal should be reported using the same 
timing as for SAEs (see Section 11.2.1).

11 SERIOUS ADVERSE EVENT 
11.1 
Definition of Serious Adverse Event 
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: 
Death 
Life-threatening 
Inpatient hospitalisation or prolongation of existing hospitalisation 
Persistent or significant disability/incapacity 
Congenital anomaly/birth defect in the offspring of a subject who received study drug 
Other: Important medical events that may not result in death, be life-threatening or 
require hospitalisation, may be considered an SAE when, based upon appropriate 
medical judgment, they may jeopardise 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 inpatient hospitalisation 
Subjects with ALT ≥3 × ULN and bilirubin ≥2 × ULN (> 35% direct) are defined as 
SAEs of special interest (important medical event). 
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, study drug-induced hepatitis that 
resolved without evidence of hepatic failure would not be considered life-threatening 
even though study drug-induced hepatitis can be fatal.  
The AEs requiring hospitalisation should be considered SAEs. Hospitalisation 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, hospitalisation 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 

16.1.1 Protocol Amendment 1 
INDV-6000-404 - SUBLOCADE Rapid Initiation Extension Study 
Confidential 
SUBLOCADE™ (extended-release buprenorphine)

outpatient setting. Complications that occur during hospitalisation are AEs. If a 
complication prolongs hospitalisation or fulfils any other serious criteria, the event is 
serious. When in doubt as to whether “hospitalisation” 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. 
11.2 
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 an 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. 
11.2.1 
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. 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 10.5 of the protocol.

In the event of an SAE, the Investigator or designee will notify Indivior Global Safety by 
completing the paper SAE Reporting Form and submitting the form to Indivior Global 
Safety via email or fax: 
Email: PatientSafetyNA@indivior.com   
Fax: (804) 423-8951 
11.2.2 
Regulatory Reporting Requirements for Serious Adverse Events  
Prompt receipt of notifications of SAEs to Indivior or designated representative from 
Investigators is essential in ensuring that legal obligations and ethical responsibilities 
regarding the safety of subjects are met.  
Indivior has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study drug.  Indivior or designated 
representative will comply with country-specific regulatory requirements pertaining to 
safety reporting to Regulatory Authorities, IRBs and Investigators.  
A suspected unexpected serious adverse reaction (SUSAR) is an SAE related to the study 
drug administered in any dose and that, in its nature or severity, is inconsistent USPI. 
Indivior Global Safety will determine if an SAE meets the definition of a SUSAR and 
distribute SUSAR reports according to local regulatory requirements and Indivior policy. 
An Investigator who receives the safety report describing an SAE or other specific safety 
information (e.g., summary or line listing of SAEs, Dear Investigator Letter) will file it 
with the USPI and will notify the IRB, if required according to local requirements.   
12 PREGNANCY  
12.1 
Collecting and Reporting Pregnancy Information  
Information on all pregnancies will be collected from receipt of study drug until 12 
months following the last dose of SUBLOCADE (approximately 5 terminal half-lives). 
All confirmed pregnancies that occur within this study will be followed until resolution 
(i.e., termination [voluntary or spontaneous] or birth).   
Pregnancy of a study subject without associated unexpected or adverse sequelae is not a 
reportable AE but must be reported to Indivior Global Safety (or designated 
representative) using the Clinical Trial Pregnancy Tracking Form within 24 hours of the 
Investigator or designee first being aware of the pregnancy (contact details for reporting 
via email or fax are the same as for SAEs).  
The pregnancy must be followed up to determine outcome (including premature 
termination) and status of mother and infant. Generally, follow-up will not be required 
for longer than 6 to 8 weeks beyond the estimated delivery date. Any termination of 
pregnancy will be reported, regardless of foetal status (presence or absence of anomalies) 
or indication for procedure.

Confidential 
SUBLOCADE™ (extended-release buprenorphine) 
Page 40 of 52 
 
 
 
 
 
 
Any pregnancy complication or elective termination for medical reasons must be reported 
as an AE or SAE. Any SAE occurring in association with a pregnancy, brought to the 
Investigator’s attention after the subject has completed the study and considered by the 
Investigator as possibly related to the study treatment, must be promptly reported to 
Indivior or designated representative. While the Investigator is not obligated to actively 
seek this information in former study subjects, he or she may learn of a pregnancy 
through spontaneous reporting.  
12.2 
Action to be Taken if Pregnancy Occurs in a Female Subject  
If a female subject suspects that she is pregnant (e.g., missed period, self-administered 
pregnancy test) between scheduled visits, the subject will be asked to return to the clinic 
at the next scheduled visit. Removal of the SUBLOCADE depot will not be required if 
pregnancy occurs. 
If a urine pregnancy test during a subject’s visit confirms that a subject is pregnant, the 
subject will receive no further injections, and the current visit will be considered the 
subject’s ET Visit. If the subject any ongoing AEs or concomitant medications at the ET 
Visit, she will also be followed up by telephone 4 weeks later for the safety follow up to 
assess the ongoing AEs or concomitant medications only. 
The Investigator should fully inform the female subject of the potential risk to the foetus.  
13 DATA MANAGEMENT 
13.1 
Data Collection and Management  
Data will be entered onto a CRF and will be managed in accordance with the data 
management plan to ensure that the integrity of the data is maintained. Adverse events 
will be coded using the Medical Dictionary for Regulatory Activities (MedDRA).. 
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.  
13.2 
Database Quality Assurance  
The CRFs will be reviewed and checked for omissions, apparent errors and values 
requiring further clarification using manual procedures. Data queries requiring 
clarification will be generated and addressed by the investigational site. Only authorized 
personnel will make corrections to the CRFs, and all corrections will be documented in 
an audit trail. 
13.3 
Source Documentation 
The Investigator is responsible for the quality of the data recorded in the CRF. The data 
recorded should be a complete and accurate account of the subject’s record collected 
during the study.

Study data will not be recorded solely onto the CRF but will be initially documented in 
source documents.  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. 
14 STATISTICS 
This section describes sample size determination, analysis populations and planned 
analyses for safety measures.  
14.1 
General Procedures 
All safety data will be listed. 
Continuous variables will be summarised using descriptive statistics such as mean, 
standard deviations (SD), median, minimum and maximum. 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 the initial screening visit to the 
safety follow up for all subjects enrolled. A statistical analysis plan (SAP) will be 
prepared after the protocol is approved and before database lock occurs. The SAP will 
provide further details regarding analysis. Additional unplanned analyses may be 
required after all planned analyses have been completed. Any deviations from the 
analyses described below will be outlined in the SAP. Any unplanned analyses will be 
clearly identified in the clinical study report. 
14.2 
Sample Size 
Up to 25 adult subjects with moderate to severe OUD are planned to be enrolled onto the 
study.  
14.3 
Analysis Populations 
The Safety population will consist of all subjects who received at least 1 dose of 
SUBLOCADE, and will be the primary population for all analyses 
14.4 
Analysis of Primary, Secondary and Exploratory Endpoints 
14.4.1 
Primary Endpoint 
All TEAEs collected during the treatment period will be presented by system organ class 
and preferred term, each in descending order of frequency, unless otherwise specified.

A TEAE is defined as an AE observed after starting administration of SUBLOCADE in 
this study. If subject experiences an event both prior to starting administration of 
SUBLOCADE and ongoing during the treatment, the event will be considered a TEAE 
(of the treatment) only if it has worsened in severity (i.e., it is reported with the date of 
worsening as the new start date/time) after starting administration of SUBLOCADE in 
this study. 
Adverse events will be coded using the most up-to-date version of the 
MedDRA dictionary and grouped by primary system organ class. The Investigator 
determines the intensity of AEs and the relationship of AEs to study therapy.  
14.4.2 
Analysis of Other Safety Data 
Drug-related TEAE, serious TEAE, drug-related serious TEAE and TEAE leading to 
treatment discontinuation will be summarised by system organ class and preferred term. 
Other safety data will be analysed using descriptive statistics for continuous endpoints 
(e.g., n, mean, median, SD, minimum and maximum) and frequency counts with 
percentages for discrete endpoints. Complete details of the safety analyses will be 
provided in the SAP. 
14.4.3 
Other Safety Variables   
The results of scheduled assessments of pregnancy tests and concomitant medications 
will be  listed. Further details will be provided in the SAP. 
Substance/drug use, detox and MOUD treatment history will be summarized and listed.  
14.5 
Demographic and Baseline Characteristics 
Demographic and disease characteristics at screening, (e.g., age, gender, race, ethnicity, 
weight, height, Body Mass index (BMI), tobacco use, alcohol use and illicit drug use, 
baseline disease history) will be summarised using descriptive statistics. Qualitative 
variables, (e.g., gender, race) will be summarised using frequencies; quantitative 
variables, (e.g., age, weight, height) will be summarised using (n, mean, SD, median, 
minimum and maximum). 
14.6 
Interim Analysis 
No formal interim analyses are planned for this study.

15 ETHICS AND RESPONSIBILITIES 
15.1 
Good Clinical Practice 
Prior to site activation, Indivior or designated representative will obtain 
approval/favourable opinion from the relevant regulatory agency(ies) to conduct the 
study in accordance with ICH/GCP and any applicable country-specific regulatory 
requirements.  
The study will be carried out in accordance to the protocol and with local legal and 
regulatory requirements, ICH/GCP and all applicable subject privacy requirements. 
15.2 
Data and Safety Monitoring Committee 
There will be no data and safety monitoring committee for this study.  
15.3 
Institutional Review Board/Independent Ethics Committee 
The protocol, ICF(s) and any other written information and/or materials to be provided to 
subjects will be reviewed by an independent and appropriately constituted IRB. If 
required by local regulations, the protocol should be re-approved by the IRB annually. 
The IRB must be constituted and operate in accordance with the principles and 
requirements of ICH/GCP.  
Study drug can only be released to the Investigator after documentation that all ethical 
and legal requirements for starting the study has been received by Indivior or designated 
representative. 
15.4 
Informed Consent 
The Investigator or a person designated by the Investigator (if allowed by local 
regulations) is to obtain written informed consent from each subject prior to entering the 
study. All written informed consent documents are required to have been reviewed and 
received a favourable opinion/approval from an IRB prior to presenting them to a 
potential participant.  
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 
Study Files and Record Retention 
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. 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 time frame. 
16 AUDITING AND MONITORING 
The purpose of an audit or regulatory inspection is to verify the accuracy and reliability 
of clinical study data submitted to a regulatory authority in support of research or 
marketing applications, and to assess compliance with statutory requirements regulations 
governing the conduct of clinical studies.   
In accordance with applicable regulations, GCP and Indivior procedures, the clinical 
monitor(s) will periodically contact the site, including conducting on-site visits at 
intervals agreed by the Investigator and documented in the Clinical Monitoring Plan and 
the Site Initiation Visit Report.  
The clinical monitor(s) will contact the site prior to the start of the study to discuss the 
protocol and data collection procedures with site personnel. In accordance with 
applicable regulations and GCP guidelines, the Investigator shall make available for 

16.1.1 Protocol Amendment 1

direct access all study-related records upon request by Indivior, Indivior’s agents, clinical 
monitor(s), auditors and/or IRB. The monitors will visit the site during the study in 
addition to maintaining frequent telephone and written communication. The extent, 
nature, and frequency of on-site visits will be based on such considerations as the study 
objectives and/or endpoints, the purpose of the study, study design complexity and 
enrolment rate.  
The Investigator must allow the clinical monitor(s) direct access to all relevant 
documents and to allocate his/her time and the time of his/her staff to the clinical 
monitor(s) to discuss findings and any relevant issues.  
Upon completion of the study, study closeout activities must be conducted by Indivior or 
its designee in conjunction with the Investigator, as appropriate.  
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 
Investigators and associated personnel before the study, periodic monitoring visits by 
Indivior, and direct transmission of clinical laboratory data from a central laboratory into 
Indivior’s (or designee’s) database. Written instructions will be provided for study drug 
preparation and dosing, collection, preparation and shipment of blood, plasma and urine 
samples. Guidelines for CRF completion will be provided and reviewed with study 
personnel before the start of the study. Indivior (or designee) will review CRFs for 
accuracy and completeness during on-site monitoring visits and after transmission to 
Indivior (or designee). Any discrepancies will be resolved with the Investigator or 
suitably qualified designee, as appropriate.  
This study will be organised, performed and reported in compliance with the protocol, 
SOPs, working practice documents and applicable regulations and guidelines.  
In accordance with the standards defined in Indivior SOPs and applicable regulatory 
requirements, clinical studies sponsored by Indivior are subject to Indivior Quality 
Assurance (QA) Investigator Site Audits that may be delegated to a contract research 
organisation or Indivior contract auditors. Investigator Site Audits will include review of, 
but are not limited to, drug supply, presence of required documents, the informed consent 
process and comparison of 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 organisation’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 substantial 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 participant, 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.

20 CONFIDENTIALITY 
All subject-identifying documentation generated in this study is confidential and may not 
be disclosed to any persons not directly concerned with the study without written 
permission from the subject. However, authorized regulatory officials and Indivior 
personnel (or their representatives) will be allowed full access to inspect and copy the 
records. All subject bodily fluids and/or other materials collected shall be used solely in 
accordance with this protocol and the ICF signed by the subject, unless otherwise agreed 
to in writing by Indivior.  
Each subject will be identified assigned subject number when reporting study information 
to any entity outside of the study centre. Data containing subject identification will not be 
removed from the clinic without first redacting subject identifiers.
