SYNOPSIS
Name of Sponsor/Company: Alkermes, Inc. 
Name of Investigational Product: ALKS 3831 
Name of Active Ingredient: Olanzapine and samidorphan 
Title of Study: A Phase 3 Study to Assess the Long-Term Safety, Tolerability, and Durability of 
Treatment Effect of ALKS 3831 in Subjects with Schizophrenia, Schizophreniform Disorder, or 
Bipolar I Disorder 
Investigator(s): This is a multinational multicenter study. 
Study Period: 
Estimated date of first subject’s consent: Q2 2017 
Estimated date of last subject’s last visit: Q4 2022 
Phase of Development: 3 
Objective: The primary objective of this study is to evaluate the long-term safety, tolerability, and 
durability of treatment effect of ALKS 3831 in subjects with schizophrenia, schizophreniform disorder, 
or bipolar I disorder. 
Methodology: This is a multicenter, open-label study to evaluate the long-term safety, tolerability, and 
durability of treatment effect of ALKS 3831 in subjects with schizophrenia, schizophreniform disorder, 
or bipolar I disorder. Subjects that have completed the antecedent studies (ALK3831-A304, 
ALK3831-A306, or ALK3831-A307) within the past 7 days will be eligible to enroll in this study. 
Subjects enrolled in the study will be started on the same olanzapine dose that they had maintained at 
the end of the antecedent study. Available doses of ALKS 3831 will be 5, 10, 15, and 20 mg olanzapine 
combined with 10 mg samidorphan (henceforth to be referred to as 5/10, 10/10, 15/10, and 20/10 mg). 
Subjects may be titrated to a different dose after the start of the study at the Investigator’s discretion. 
Dosing will be flexible throughout the study; however, frequent adjustments are discouraged. Dose 
adjustments will only be performed on-site at the study center. Subjects requiring dose adjustments 
between scheduled visits will need to arrange an unscheduled visit. 
Safety assessments will include adverse event (AE) monitoring, clinical laboratory testing, vital signs, 
body weight, electrocardiograms (ECGs), and the Columbia-Suicide Severity Rating Scale (C-SSRS). 
Psychiatric symptoms will be evaluated using the Clinical Global Impressions-Severity (CGI-S) scale. 
Additional assessments will include Impact of Weight on Quality of Life-Lite Questionnaire 
(IWQOL-Lite). A schematic summarizing study design is presented below.

Number of Subjects Planned: Approximately 500 subjects 
Main Criteria for Inclusion: Subjects will have completed the treatment period in one of the 
following antecedent studies within 7 days: ALK3831-A304, ALK3831-A306, or ALK3831-A307. 
Subjects will have potential to benefit from ALKS 3831 in the opinion of the investigator, and agree to 
use an acceptable method of contraception during the study and until 30 days after any study drug 
administration, unless surgically sterile or post-menopausal. 
Main Criteria for Exclusion: Subjects may be excluded based on positive tests for drugs of abuse at 
study entry, any finding that would compromise the subject’s safety or their ability to fulfill the study 
requirements, pregnancy or breastfeeding, or employment by (or relationship to an employee of) the 
study sponsor, clinical research organization, or study site. 
Investigational Product, Dosage, Duration, and Mode of Administration: ALKS 3831 refers to the 
fixed dose combination of olanzapine and samidorphan. ALKS 3831 will be supplied as a coated 
bilayer tablet containing 5, 10, 15, or 20 mg olanzapine and 10 mg samidorphan. The tablet will be 
taken by mouth once daily, preferably at bedtime, for at least 24 but not more than 48 months. The 
study is planned to be open until approximately the 4th quarter 2022 or until regulatory action. 
Therefore, depending on when a subject is enrolled, the duration of participation in this study will vary. 
Reference Therapy, Dosage, Duration, and Mode of Administration: None 
Duration of Study: The total study duration will be up to 49 months, including a treatment period of 
24 to 48 months and a 4-week safety Follow-up period. 
Criteria for Evaluation: 
Safety and Tolerability: The following parameters will be collected to measure safety and tolerability 
throughout the study: 
• 
AEs (including clinically significant abnormal ECG findings) 
• 
Vital signs (oral temperature, respiratory rate, blood pressure, and heart rate) 
• 
Weight and waist circumference 
• 
Clinical laboratory parameters (biochemistry, hematology, and urinalysis) 
• 
C-SSRS 
Efficacy: Throughout the study, CGI-S scores will be collected to measure the durability of treatment 
effect. 
Other: Throughout the study, IWQOL-Lite scores will be collected to obtain information regarding 
subject experience. 
Endpoints: 
Safety and Tolerability Endpoints: 
• 
Incidence of AEs

INTRODUCTION 
5.1. 
Background 
Olanzapine has been commercially available for over 20 years as a treatment for schizophrenia 
and bipolar I disorder (see local olanzapine label) and is regarded as a highly effective treatment 
with demonstrated antipsychotic efficacy and decreased incidence of extrapyramidal symptoms. 
However, the greater antipsychotic efficacy of olanzapine is undermined by its propensity to 
cause significant weight gain and increased cardio metabolic risk compared to other atypical 
antipsychotic drugs (Allison et al, 1999; Leucht et al, 2013; Lieberman et al, 2005; Meyer et al, 
2008; Wirshing et al, 1999). Olanzapine is also recommended as a second-line treatment in 
patients early in illness according to the Schizophrenia Patient Outcomes Research Team 
(PORT) treatment guidelines (Buchanan et al, 2010). This is largely due to the fact that 
olanzapine-induced weight gain and metabolic risk is especially pronounced in patients who are 
early in illness for both schizophrenia and bipolar disorder (Correll et al, 2014). 
Alkermes is developing ALKS 3831 as a fixed-dose combination of olanzapine and samidorphan 
(a µ-opioid receptor antagonist), for the treatment of schizophrenia designed to combine the 
antipsychotic efficacy of olanzapine with a reduced risk of weight gain and associated metabolic 
deficits. The novel combination of olanzapine and samidorphan in ALKS 3831 has the potential 
to deliver the therapeutic benefits of olanzapine to patients while avoiding the harmful weight 
gain and associated metabolic risks. 
Development of ALKS 3831 as a fixed-dose combination of olanzapine and samidorphan has the 
potential to improve upon the benefit/risk profile of olanzapine alone and address a significant 
clinical need for patients that are currently forced to choose between treatment efficacy and 
safety. Four Phase 3 studies (ALK3831-A303, ALK3831-A304, ALK3831-A305, and 
ALK3831-A306) are ongoing to assess the efficacy, associated weight changes, and safety of 
ALKS 3831 in subjects with schizophrenia. One Phase 3 study (ALK3831-A307) is planned to 
begin enrollment in 2017 and will evaluate the effect of ALKS 3831 compared to olanzapine on 
body weight in young adults with schizophrenia, schizophreniform, or bipolar I disorder with a 
recent onset of symptoms and early in medical treatment. 
5.2. 
Study Drugs 
In this study a fixed dose combination of olanzapine and samidorphan will be administered in a 
single bilayer tablet. The following sections provide an overview of samidorphan and 
olanzapine. Detailed information about the study drugs can be found in the current 
ALKS 3831 Investigator’s Brochure.

5.2.1. 
Samidorphan 
Samidorphan is a new molecular entity in clinical development by Alkermes. Samidorphan is a 
µ-opioid receptor antagonist. It is currently being investigated in combination with olanzapine 
for the treatment of schizophrenia (ALKS 3831) and in combination with buprenorphine for the 
treatment of major depressive disorder (ALKS 5461). Based on its chemical structure, 
samidorphan is considered a Schedule II controlled substance according to the US Drug 
Enforcement Agency and will require proper handling (see Section 10.5). At least 10 clinical 
studies of samidorphan have been conducted to date, eight of which included subjects that 
received samidorphan alone (not in combination with another product). Overall, over 
2000 subjects have been exposed to samidorphan as a single agent or in combination with 
olanzapine or buprenorphine in completed and ongoing clinical studies. Commonly reported 
adverse events (AEs) observed across all studies included nausea, fatigue, and somnolence. 
Overall, no trends or clinically meaningful changes have been observed in clinical laboratory 
analytes, vital sign parameters, or electrocardiogram (ECG) data. 
5.2.2. 
Olanzapine 
Olanzapine has been commercially available for over 20 years as a treatment for schizophrenia 
and bipolar I disorder (see local olanzapine label). The safety and tolerability profile of 
olanzapine is well documented, and AE labeling is supported by an extensive safety database 
with over 20 years of post-marketing experience (see local olanzapine label). Commonly 
reported AEs consistent across all or most dosage forms in short-term, placebo controlled trials 
include somnolence, constipation, dry mouth, accidental injury, weight gain, postural 
hypotension, dizziness, asthenia, fever, and abnormal gait. 
5.3. 
Study Rationale 
This Phase 3 study is an extension study (for antecedent studies ALK3831-A304, 
ALK3831-A306, and ALK3831-A307) that will evaluate the long-term safety, tolerability, and 
durability of treatment effect of ALKS 3831 in subjects with schizophrenia, schizophreniform 
disorder, or bipolar I disorder. This study will extend subject exposure by up to 4 years, and 
provide valuable safety and tolerability data over the longest treatment durations evaluated so far 
(up to 5.5 years). Information regarding non-clinical and clinical studies completed to date with 
ALKS 3831 is available in the current version of the Investigator’s Brochure.

5.4. 
Dose Rationale 
All subjects will receive ALKS 3831. The doses of ALKS 3831 will be 5, 10, 15, and 20 mg 
olanzapine combined with 10 mg samidorphan (henceforth to be referred to as 5/10, 10/10, 
15/10, and 20/10 mg). These doses represent the intended therapeutic doses of ALKS 3831 and 
include the full range of doses used in all antecedent studies. The 10 mg samidorphan dose was 
identified as the minimal effective dose based on the efficacy and optimal safety profile observed 
in Study ALK3831-302. A fixed dose of samidorphan was selected due to the fact that data from 
Study ALK3831-302 demonstrated no correlation between the ratio of samidorphan/olanzapine 
dose and percent change from baseline in body weight after 12 weeks of treatment, indicating 
that even with higher olanzapine doses, a fixed dose of samidorphan is sufficient to achieve 
maximal effect in reducing olanzapine-induced weight gain. 
5.5. 
Benefit-Risk Assessment 
As stated in the background section, first- and early-episode schizophrenia and bipolar I disorder 
are critical phases of the diseases, where optimal antipsychotic efficacy is crucial. Treatment 
with ALKS 3831 combines the advantages of the antipsychotic efficacy of olanzapine in treating 
both schizophrenia and bipolar disorder, with the potential to mitigate the known effect of 
olanzapine treatment of excessive weight gain. The antipsychotic efficacy seen in stable subjects 
treated in study ALK3831-302 was similar between ALKS 3831 and olanzapine as measured by 
Total PANSS and CGI scores. Based on the available data from the completed studies in healthy 
volunteers (ALK33-301) and in subjects with schizophrenia (ALK3831-302), subjects treated 
with ALKS 3831 have been shown to gain less weight compared to subjects treated with 
olanzapine alone. In ALK3831-302, the prevention of weight gain persisted during the 3 month 
ALKS 3831 treatment period. 
The important identified risks associated with the use of olanzapine include weight gain, glucose 
dysregulation, and dyslipidemia. For additional information on the known risks of olanzapine, 
see the local label. The safety profile of ALKS 3831 is consistent with that of olanzapine (see 
local label). In study ALK3831-302, the only adverse events reported with ALKS 3831 treatment 
occurring in ≥5% of subjects and at ≥2 times the rate of olanzapine alone were somnolence, 
sedation, dizziness, and constipation. Notably, these are all labeled events for olanzapine. The 
most common adverse events noted in clinical studies in >2% of subjects with ALKS 3831 to 
date have been somnolence, dizziness, weight increased, sedation, increased appetite, headache, 
orthostatic hypotension, and liver function test abnormal (see current ALKS 3831 Investigator’s 
Brochure). In summary, data from the completed ALKS 3831 studies have demonstrated a 
favorable benefit-risk profile for further investigating ALKS 3831 in subjects with 
schizophrenia, schizophreniform disorder, or bipolar I disorder.

7.3. 
Subject Withdrawal 
A subject may be discontinued from the study at any time if the subject, Investigator, or Sponsor 
determines that it is not in the best interest of the subject to continue participation. If a subject 
has an absolute neutrophil count (ANC) < 1.0 × 103 per µL or Hemoglobin A1c (HbA1c) ≥6.5% 
at any time, the PI (or designee) should discontinue the subject from participation immediately. 
Reasons for discontinuation include: 
• Adverse Event 
• Lack of Efficacy 
• Lost to Follow-up 
• Withdrawal by Subject 
• Protocol Deviation (including non-compliance with study drug or study procedures) 
• Pregnancy 
• Study Terminated by Sponsor 
• Other 
If a subject withdraws from the study for any reason, any ongoing AEs will be followed until 
resolution, until deemed stable by the Investigator, or until the subject is deemed by the 
Investigator to be lost to follow-up. If, in the opinion of the Investigator, it is necessary to 
monitor a subject beyond the safety follow-up visit, the follow-up period may be extended as 
necessary. In such instances, the Sponsor and Investigator will agree to an acceptable follow-up 
schedule. 
In the event that a subject chooses to withdraw from the study, the Investigator should make a 
reasonable effort to ascertain the reason(s) for withdrawal, while fully respecting the subject’s 
rights. Subjects who terminate the treatment early (prior to Visit 25) will complete an early 
termination (ET) visit and the 4-week Safety Follow-up period. The ET visit should be scheduled 
as close as possible to the subject’s last dose and will mimic the assessments scheduled to be 
conducted at the EOT Visit. If the subject fails or refuses to return to the study center, an attempt 
must be made to contact the subject by telephone in order to assess as many safety and efficacy 
parameters as possible. All data collected over the telephone must be documented and kept in the 
subject’s record. 
The Investigator must maintain a record of all subjects who fail to complete the study. The 
reason for study discontinuation will be documented and made on the appropriate electronic case 
report form (eCRF). If a subject is lost to follow-up, a reasonable attempt to contact the subject 
must be made and documented. 
7.4. 
Replacement of Subjects 
Subjects who withdraw from the study will not be replaced.

STUDY DESIGN 
8.1. 
Overall Study Design and Plan 
This is a multicenter, open-label study to evaluate the long term safety, tolerability, and 
durability of treatment effect of ALKS 3831 in subjects with schizophrenia, schizophreniform 
disorder, or bipolar I disorder. Subjects that have completed the antecedent studies 
(ALK3831-A304, ALK3831-A306, or ALK3831-A307) within the past 7 days will be eligible to 
enroll in this study. 
Subjects enrolled in the study will be started on the same olanzapine dose that they had 
maintained at the end of the antecedent study. Available doses of ALKS 3831 will be 5/10, 
10/10, 15/10, and 20/10 mg. Subjects may be titrated to a different dose after the start of the 
study at the Investigator’s discretion. Dosing will be flexible throughout the study; however, 
frequent adjustments are discouraged. Dose adjustments will only be performed on-site at the 
study center. Subjects requiring dose adjustments between scheduled visits will need to arrange 
an unscheduled visit. 
Safety assessments will include AE monitoring, clinical laboratory testing, vital signs, body 
weight, ECGs, and the Columbia-Suicide Severity Rating Scale (C-SSRS). Psychiatric 
symptoms will be evaluated using the CGI-S scale. Additional assessments will include Impact 
of Weight on Quality of Life-Lite Questionnaire (IWQOL-Lite).  
The duration of the treatment period will vary by subject, between 24 and 48 months, or until 
regulatory action; duration will vary by subject. The study completion is targeted for the 4th 
quarter of 2022. After the last subject is enrolled, the end date of the study will be set to occur 24 
months later (approximately the 4th quarter of 2022), and subjects will be informed of the target 
completion date. The total study duration will be up to 49 months including a treatment period of 
24 to 48 months and a 4-week safety Follow-up period and return to their normal standard of 
care once their participation has ended. A schematic of the study design is provided in Figure 1. 
The end of trial is defined as the date of the last subject’s last visit.

Study Procedures Descriptions 
Details of the study procedures are described below. The overall schedule of assessments is 
provided in Table 3. 
8.3.1. 
Informed Consent 
The nature of the study and its risks and benefits will be explained to the subject by the Principal 
Investigator (PI) or designated study personnel as outlined in Section 17.3. 
Prior to the administration of any study-specific procedures, authorized study personnel will 
obtain written informed consent/assent as per local requirements from each potential subject as 
specified in Table 3. 
8.3.2. 
Eligibility Review 
An eligibility review will be conducted by the Investigator at the visits specified in Table 3 using 
the subject inclusion criteria in Section 7.1 and exclusion criteria in Section 7.2.  
8.3.3. 
Demographics and Medical / Psychiatric History 
Subject’s demographic data and medical / psychiatric history (including primary psychiatric 
diagnosis) will be carried over from the antecedent studies (ALK3831-A304, ALK3831-A306, 
or ALK3831-A307). 
8.3.4. 
Concomitant Medication Review 
At the timepoints specified in Table 3, subjects will be asked about the medications they have 
taken since their last visit, including prescription and nonprescription medications, vitamins, and 
supplements. 
The investigator will record the following data on all medications used by the subject: name, 
dose, regimen, route of administration, start and stop dates, and the indication for use. 
8.3.5. 
Vital Signs 
Vital signs (ie, blood pressure, pulse, respiratory rate, and oral body temperature) will be 
assessed at the timepoints specified in Table 3. An effort will be made to consistently use the 
same arm (preferably the subject’s dominant arm) to measure blood pressure and heart rate 
throughout the study. The blood pressure cuff will be calibrated per study site standard operating 
procedures. Automated measurement is preferred, but if performed manually, heart rate will be 
measured in the brachial artery for at least 30 seconds. 
Blood pressure, heart, and respiratory rate will be measured after the subject has been in the 
supine position for at least 5 minutes. Vital signs may be collected at any time during a 
scheduled visit, unless otherwise noted. 
8.3.6. 
Physical Examination 
A brief physical examination and an ECG (local) will be performed at the timepoints specified in 
Table 3. 

 
 
Alkermes, Inc. 
Protocol ALK3831-A308 Amendment 3.0 
 
CONFIDENTIAL 
Page 22 of 49 
8.3.7. 
Weight and Waist Circumference 
Weight and waist circumference will be measured at all the timepoints specified in Table 3. 
For weight measurements, subjects should be asked to void immediately prior to measurement 
and should be dressed in a hospital gown with consistent under-attire for each measurement. 
Subjects should remove all personal items (including shoes, watches, and jewelry) and they 
should be weighed on the same scale for each measurement under the same conditions. 
Both weight and waist circumference will be measured three consecutive times at each 
assessment and all measurements will be recorded in the eCRF. 
8.3.8. 
Structured Interviews and Questionnaires 
Brief descriptions of each of the interviews and questionnaires to be distributed are available 
below. All interviews and questionnaires will be administered by trained and qualified study 
personnel. 
For assessments performed at multiple visits, every effort should be made to pair the same 
clinician / rater with the same subject across visits. 
Table 3 provides information on the timepoints at which each assessment should be 
administered. 
8.3.8.1. 
Safety Assessments 
8.3.8.1.1. Columbia-Suicide Severity Rating Scale 
The PI or designee will administer C-SSRS according to the timepoints in Table 3. The “Since 
Last Visit” version of the C-SSRS will be used at all indicated visits. The C-SSRS should be 
administered by a qualified clinician trained in assessing and managing suicidal ideation and 
behavior (Posner et al, 2011). 
8.3.8.2. 
Psychiatric/Quality of Life Assessments 
8.3.8.2.1. Clinical Global Impressions-Severity 
The PI or designee will complete the CGI-S scale at the timepoints specified in Table 3. The 
CGI-S measures mental illness severity. Clinicians are asked to rate subjects based on their prior 
experience working with individuals in a similar patient population (Guy 1976). 
8.3.8.2.2. Impact of Weight on Quality of Life-Lite 
Subjects will complete the IWQOL-Lite questionnaire (Kolotkin et al, 2001) at the timepoints 
specified in Table 3. 
8.3.9. 
Laboratory Assessments 
8.3.9.1. 
Drug Testing 
A urine drug test for opioids and drugs of abuse, including amphetamine/methamphetamine, 
phencyclidine, and cocaine, will be performed at the timepoints specified in Table 3. Results 
must be negative for the subject to be eligible for the study. The urine drug screen will be

performed at Visit 1; however if Visit 1 is the same as the end of treatment visit of the antecedent 
study and a urine drug screen was already performed during that visit, it doesn’t need to be 
repeated. The urine drug screen may be repeated at any point during the study based on the 
investigator’s discretion. 
8.3.9.2. 
Hematology, Biochemistry, and Urinalysis 
Blood and urine samples for laboratory assessments will be collected at the timepoints specified 
in Table 3. Specific hematology, biochemistry, and urinalysis assessments are listed in Table 4. 
Subjects will be instructed not to eat or drink anything (except water) for 8 hours before each 
visit where blood samples for biochemistry and hematology assessments will be collected. 
Samples will be collected in accordance with the site’s usual procedures and analyzed by a 
central laboratory. Laboratory assessments may be repeated at the Investigator’s discretion.

Drug Dispensation and Reconciliation 
Section 9 provides information related to drug dispensing procedures. Study drug will be 
dispensed/administered at the timepoints specified in Table 3. The study drug use and storage 
information will be explained to/reviewed with the subject. 
8.3.11. 
Emergency Treatment Card 
An emergency treatment card will be distributed to each subject at Visit 1 and collected at the 
EOT/ET Visit. The card will indicate that the subject is receiving an opioid antagonist and 
olanzapine and will include the PI’s contact information, a suggested pain management plan and 
information regarding opiate blockade. Subjects will be instructed to keep the card with them at 
all times. Study personnel will confirm that subjects have the card in their possession at each 
study visit. 
8.3.12. 
Adverse Event Monitoring 
All AEs will be monitored continuously from the time a subject signs the informed consent 
document until the completion of the final study visit (see Table 3). All AEs ongoing at the end 
of trial or concomitant medications continuing from the antecedent study will be carried over and 
followed until resolution. All AEs and serious adverse events (SAEs) are defined in Section 13.2 
and Section 13.3, respectively. Section 13.5 provides guidance on the monitoring and recording 
requirements for AEs. Section 13.6 provides guidance on the reporting requirements for SAEs. 
8.4. 
Study Requirements and Restrictions 
8.4.1. 
Contraception and Pregnancy 
All male and female subjects must agree to use an acceptable method of contraception for the 
duration of the study. All female subjects must agree to use an acceptable method for 30 days 
after the last dose of study drug, unless they are surgically sterile or postmenopausal (see below). 
The following are considered acceptable methods of contraception: 
1. Intrauterine device 
2. Oral contraceptive pills and other hormonal methods (eg, a vaginal ring, contraceptive 
patch, contraceptive implant) 
3. Double-barrier protection (eg, a condom with spermicide or a diaphragm with 
spermicide) 
4. Abstinence (see below) 
Subjects who are abstinent are eligible, provided they agree to use an acceptable contraceptive 
method should they become sexually active. Abstinence is defined as “true abstinence” in which 
subjects must refrain from heterosexual intercourse for the full duration of the study and must be 
in line with the preferred and usual lifestyle of the subject. Periodic abstinence (eg, calendar, 
ovulation, symptothermal, postovulation methods), declaration of abstinence for the duration of 
exposure to the study drug, and withdrawal are not acceptable methods of contraception. 
Subjects who are surgically sterile are exempt from the requirement to use contraception. 
Women who have undergone a hysterectomy, bilateral tubal ligation, or bilateral 

 
 
Alkermes, Inc. 
Protocol ALK3831-A308 Amendment 3.0 
 
CONFIDENTIAL 
Page 26 of 49 
salpingo-oophorectomy are considered surgically sterile. Men who have undergone a vasectomy 
are considered surgically sterile. Partner vasectomy is not considered an approved acceptable 
method of contraception for a female subject. 
Women who are postmenopausal are also exempt from the requirement to use contraception. For 
the purpose of this study, postmenopausal is defined as the permanent cessation of menstruation 
for at least 12 months prior to Screening in women who are 45 years of age or older. 
If a subject becomes pregnant while participating in the study, she will be discontinued from 
study drug immediately. The ET and safety follow-up visits will be scheduled and the pregnancy 
will be reported to Alkermes. Additional follow-up may be required.  Pregnancies in female 
partners of male subjects should also be reported and will be followed in the same manner. If a 
male subject has a partner who becomes pregnant, the partner may need to provide written 
informed consent to obtain pregnancy follow-up information, as per local requirements. 
A Pregnancy Report Form must be submitted to Alkermes via 
 
(per Section 13.6) immediately, within 24 hours of awareness of the pregnancy, irrespective of 
whether an AE has occurred. The pregnancy will be followed until completion or termination. If 
the outcome of the pregnancy meets the criteria for classification as an SAE, it should be 
reported following the SAE procedure (see Section 13.6). 
8.4.2. 
Prohibited Medications 
In this study, the medications listed below are prohibited: 
• Antipsychotic medications for any indication 
• Diabetes treatments and hypoglycemic agents including Metformin and Insulin 
• Moderate to strong inhibitors or inducers of cytochrome P450 (CYP) 3A (prescription 
medications, OTC medications, or dietary supplements) within 30 days before 
enrollment through Follow-up (refer to Section 20 for a list of CYP3A inhibitors and 
inducers) 
• Use of opioid antagonists, including naltrexone (any formulations) and naloxone 
• Opioid agonists should be avoided as they may be rendered ineffective by 
samidorphan 
The CRO Medical Monitor should be consulted for any questions about use of any psychotropic 
medications during a subject’s participation in this study. 
8.4.3. 
Permitted Medications 
In this study, the medications listed below are permitted: 
• Medications that exhibit drug interaction potential with olanzapine, including known 
inhibitors and inducers of CYP1A2 (Section 21), may affect olanzapine 
concentrations. Hence, investigators must use caution with inhibitors and inducers of 
CYP1A2 and monitor for need for study drug dose adjustment 
• Medicinal products known to be associated with increase in QTc interval should be 
used with caution given the increased risk of torsade de pointes (Section 22) 

 
 
Alkermes, Inc. 
Protocol ALK3831-A308 Amendment 3.0 
 
CONFIDENTIAL 
Page 27 of 49 
• Oral contraceptive pills and other hormonal methods (eg, a vaginal ring, 
contraceptive patch, contraceptive implant) will be permitted 
• Permissible medications to treat extrapyramidal symptoms may include 
benzodiazepines, antihistamines, and anticholinergics. Benzodiazepines should be 
utilized for treatment-emergent akathisia 
• Treatment of agitation and/or anxiety with benzodiazepines is permissible 
8.4.4. 
Pain Management 
Because ALKS 3831 contains samidorphan, a μ-opioid antagonist, patients may experience 
reduced or ineffective analgesia when taking an opioid analgesic agent concurrently with 
ALKS 3831, including several days after last dosing of ALKS 3831. 
In the event of an emergency, pain management of the subject should include the following: 
• Regional analgesia or use of non-opioid analgesics 
• If opiate anesthesia or analgesia is required, the subject should be continuously 
monitored, in an anesthesia care setting, by persons not involved in the conduct of the 
surgical or diagnostic procedure. The opioid therapy must be provided by individuals 
specifically trained in the use of anesthetic drugs and the management of the 
respiratory effects of potent opioids, specifically the establishment and the 
maintenance of a patent airway and assisted ventilation 
• Close monitoring by appropriately trained personnel in a setting equipped and staffed 
for cardiopulmonary resuscitation 
For subjects requiring emergency opioid analgesics prior to dosing, the study drug should not be 
administered. If opioid analgesics are required after the study drug has been dosed, it may take 
several days for opiate sensitivity to be restored, since samidorphan functions as a μ-opioid 
antagonist and could interfere with opioid-mediated pain management. 
8.4.5. 
Fasting 
Subjects are required to fast for at least 8 hours (no food or drink except water) prior to 
laboratory blood draws. 
8.4.6. 
Other Restrictions and Requirements 
Additional restrictions and requirements include: 
• Prohibited substances include opioids, amphetamines (including methamphetamine), 
cocaine, and phencyclidine 
• Subjects will be required to abstain from blood or blood product donation during the 
study and for 30 days following the follow-up visit 
• Subjects will be instructed to maintain their normal caffeine intake and/or tobacco use 
as well as normal activity/exercise throughout the study. Subjects will be asked to 
abstain from strenuous physical activity for 48 hours prior to each study visit

TREATMENT OF SUBJECTS 
9.1. 
Study Drug Dose and Administration 
The study drug, ALKS 3831 will be available in the following doses: 
• ALKS 3831 5/10, 10/10, 15/10, and 20/10 administered as a coated bilayer tablet 
Subjects enrolled in the study will be started on the same olanzapine dose that they had 
maintained at the end of the antecedent study. Subjects may be titrated to a different dose after 
the start of the study at the Investigator’s discretion. Dosing will be flexible throughout the 
study; however, frequent adjustments are discouraged. Dose adjustments will only be performed 
on-site at the study center. 
Subjects will be given study drug to take home and instructed to take one tablet orally preferably 
at bedtime. If there are tolerability problems, dosing may be switched to another time based on 
the judgment of the Investigator; frequent switching is discouraged. 
Subjects will be instructed to keep all unused tablets in their blister card and to return unused 
tablets to the study site at their next visit. If dosing is to occur at that visit, the dose should be 
taken from the subject’s next blister card, not from the card they are returning. 
If a dose is missed or forgotten, subjects will be instructed to resume regular dosing the 
following night. Subjects will be instructed not to take a double dose to try to “make up” for the 
missed dose. 
9.2. 
Treatment Adherence 
Subjects will undergo a study drug adherence review at the timepoints indicated in Table 3. 
Subjects will be instructed to keep all unused tablets in their original containers and to return the

STUDY DRUG MATERIALS AND MANAGEMENT 
10.1. 
Study Drug 
The ALKS 3831 drug product will be supplied as a coated bilayer tablet in four fixed-dose 
combinations: 
• ALKS 3831 5/10 (5 mg olanzapine/10 mg samidorphan) 
• ALKS 3831 10/10 (10 mg olanzapine/10 mg samidorphan) 
• ALKS 3831 15/10 (15 mg olanzapine/10 mg samidorphan) 
• ALKS 3831 20/10 (20 mg olanzapine/10 mg samidorphan) 
The tablets contain olanzapine and samidorphan L-malate (RDC-0313-02), and the following 
excipients commonly used in pharmaceutical drug products: microcrystalline cellulose, lactose 
monohydrate, crospovidone, colloidal silica dioxide, and magnesium stearate. 
The tablet coating contains hydroxypropyl methylcellulose 2910 (HPMC 2910), titanium 
dioxide, lactose monohydrate, and triacetin as well as one or more of the following dye 
components; iron oxide yellow, iron oxide red, and/or FD&C blue #2/indigo carmine AL. 
10.2. 
Packaging and Labeling 
ALKS 3831 will be supplied in blister packs. Blister cards will be in biweekly configurations. 
Biweekly blister cards will contain 16 tablets, enough for 2 weeks of dosing plus sufficient 
overage for 2 additional once daily doses. 
10.3. 
Storage 
Product should be stored at no more than 25°C. 
Under the US Controlled Substances Act, samidorphan is considered a Schedule II substance 
because it is derived from opium alkaloids. Therefore, ALKS 3831 must be stored in accordance 
with restrictions related to Schedule II substances. The site will take adequate precautions, 
including storage of the investigational drug in a securely locked, substantially constructed 
cabinet, or other securely locked, substantially constructed enclosure, access to which is limited, 
to prevent theft or diversion of the substance. 
10.4. 
Accountability 
The clinical site is required to maintain current drug dispensation and accountability logs 
throughout the study. All unused supplies will be checked against the drug movement records 
during the study and/or at the end of the study. 
Refer to Section 8.3.10 for additional study drug reconciliation procedures. 
10.5. 
Handling and Disposal 
Following completion and verification of accountability logs, all unused and used packages must 
be destroyed. Packages may be destroyed on site according to Good Clinical Practice (GCP) and

ASSESSMENT OF SAFETY 
Safety will be assessed on the basis of: 
• AEs (including clinically significant abnormal ECG findings) 
• Vital signs (oral temperature, respiratory rate, blood pressure, and heart rate) 
• Weight and waist circumference 
• Clinical laboratory parameters (biochemistry, hematology, and urinalysis) 
• C-SSRS results 
13.1. 
Safety Endpoints 
• Incidence of AEs 
• Percent change from baseline in body weight by visit 
• Absolute change from baseline in body weight by visit 
• Change from baseline in waist circumference by visit 
13.2. 
Definition of Adverse Event 
An AE is any untoward medical occurrence in a patient or clinical investigation subject who has 
been administered a pharmaceutical product. The occurrence, which may or may not have a 
causal relationship with the investigational treatment, may include any clinical or laboratory 
change that does not commonly occur in that subject and is considered clinically significant. 
Illnesses present prior to the subject signing the informed consent form (ICF) are considered to 
be pre-existing conditions and are documented on the medical history eCRF. Pre-existing 
conditions that worsen during the study are entered on the AE eCRF. 
All out-of-range laboratory values will be deemed as clinically significant or not clinically 
significant by the Investigator. Clinically significant values will be considered AEs and will be 
recorded as such on the eCRFs. 
Pregnancy is not considered an AE, although a subject will be withdrawn from the study if a 
pregnancy occurs. As described in Section 8.4.1, the pregnancy, including a partner’s pregnancy, 
must be reported to Alkermes, and additional follow-up may be required.  
Transition from schizophreniform to schizophrenia is not considered an AE unless deemed so by 
the Investigator. 
13.3. 
Definition of Serious Adverse Event 
An SAE is any AE, occurring at any dose and regardless of causality, that: 
• Results in death 

 
 
Alkermes, Inc. 
Protocol ALK3831-A308 Amendment 3.0 
 
CONFIDENTIAL 
Page 35 of 49 
• Is life-threatening. The subject is at immediate risk of death from the reaction as it 
occurs. This does not include reaction that, had it occurred in a more severe form, 
might have caused death 
• Requires inpatient hospitalization or prolongation of existing hospitalization 
• Results in persistent or significant disability/incapacity (eg, a substantial disruption of 
a person’s ability to conduct normal life functions) 
• Is a congenital anomaly/birth defect 
Important medical events that may not result in death, be immediately life threatening, or require 
hospitalization may be considered to be SAEs when, based upon appropriate medical judgment, 
they may jeopardize the patient or subject and may require intervention to prevent one of the 
other outcomes listed above. Admission to an inpatient unit or hospital for a nonmedical or 
nonbehavioral reason (ie, social stay admission) during the study in the absence of untoward 
medical occurrence will not be considered an SAE, but will be reported as an AE. 
Hospitalization due to worsening of behavioral health related issues should be reported as 
an SAE. 
13.4. 
Relationship to Study Drug 
The assessment of study drug relationship to each AE will be reported on the appropriate source 
document (and SAE form, in the event of an SAE) by the Investigator (or designated 
Sub-Investigator) according to his/her best clinical judgment. The criteria listed in Table 5 
should be used to guide this assessment. Please note that not all criteria must be present to be 
indicative of a particular drug relationship. All study drugs are considered “test drugs” for the 
purposes of the definitions listed in the table.

ETHICAL CONSIDERATIONS 
17.1. 
Ethics Review 
The clinical site’s IRB/IEC must meet all relevant regulatory requirements. The study protocol 
and ICF will be reviewed by the IRB/IEC prior to enrolling subjects into the study; written 
approval from the committee must be received by Alkermes before drug will be released to 
the investigator. The protocol must be re-approved by the IRB/IEC upon receipt of amendments 
and annually, as local regulatory requirements require.  
The Investigator is responsible for submitting all protocol changes and SAE reports to the 
IRB/IEC according to local procedures. At a minimum, all SAEs requiring an investigational 
new drug safety report must be immediately reported. 
All relevant correspondence from the IRB/IEC will be forwarded by the respective study site to 
the Sponsor in a timely fashion. 
17.2. 
Ethical Conduct of the Study 
This study will be conducted in accordance with the protocol, the ICH Guideline E6, and all 
applicable local regulatory requirements. Good Clinical Practice (GCP) is an international ethical 
and scientific quality standard used for designing, conducting, recording, and reporting studies 
involving the participation of human subjects. Alkermes is committed to complying with this 
standard to provide assurance that the rights, safety, and well-being of study subjects will be 
protected, consistent with the principles having their origin in the Declaration of Helsinki. 
17.3. 
Written Informed Consent 
The Investigator (or authorized designee) at each center will ensure that the subject and 
parent/caregiver (as per local requirements or the subject’s legal representative) is given full and 
adequate oral and written information about the nature, purpose, potential and possible risks and 
benefits of the study. Each prospective subject and parent/caregiver (as per local requirements) 
will receive an IRB-approved ICF that summarizes the pertinent study information and will be 
given ample time to read the form and ask questions about the study. All information is to be 
provided in a language understandable to the subject and must not include any language that 
waives the subject’s legal rights. Prospective subjects must also be informed of their right to 
withdraw consent without prejudice at any time during the study. If the subject chooses to 
participate, he/she must sign the ICF/assent form (as per local requirements) and if required, the 
parent/caregiver must sign the parent/caregiver ICF before any study-specific procedures are 
conducted. 
All subjects will be informed of their rights to privacy and will be made aware that the study data 
will be submitted to Alkermes, the IRB, the contract research organization (CRO), if applicable, 
and to regulatory authorities for review and evaluation for the duration of the study and until the 
project has been approved for marketing, or is withdrawn from investigation. They will also be 
informed that the study monitor may inspect their medical records to verify the accuracy and 
completeness of the study records and results.

DATA HANDLING AND RECORDKEEPING 
An overview of study data handling and recordkeeping procedures and restrictions is provided in 
the subsequent sections; please refer to the CSA for further details. 
18.1. 
Data Capture 
As stated in Section 16.1, this study will use eCRFs for capturing data. All entries, corrections, 
and alterations will be made by the Investigator or other authorized study personnel. All data 
entries will be verified for accuracy and correctness by independent monitors. The electronic 
data capture system maintains a full audit trail. 
A paper copy of all laboratory reports will remain with the source documents at the study site. 
All electronic source data collected outside of the eCRF, such as e-diaries, central laboratory, or 
central MRI data, will be transferred directly to EDC or directly to Alkermes for incorporation 
into the final datasets. All out-of-range laboratory values will be deemed as clinically significant 
or not clinically significant by the Investigator. Clinically significant values will be considered 
AEs and will be recorded as such on the eCRFs. 
All AEs will be coded using MedDRA. Concomitant medications will be categorized using the 
WHO-ATC classification system. 
18.2. 
Inspection of Records 
Alkermes or its representative will be allowed to conduct site visits to the investigational 
facilities for the purpose of monitoring any aspect of the study. The Investigator agrees to allow 
the monitor to inspect the drug storage area, study drug stocks, drug accountability records, 
subject charts and source documents, and other records relative to study conduct. 
18.3. 
Retention of Records 
Retention and storage of all essential clinical study documents shall be governed by the terms 
and conditions of the site’s CSA and in accordance with ICH guidelines/local regulatory 
requirements as follows: 
Essential documents should be retained until at least 2 years after the last approval of a 
marketing application in an ICH region and until there are no pending or contemplated marketing 
applications in an ICH region, or at least 2 years have elapsed since the formal discontinuation of 
clinical development of the investigational product. These documents should be retained for a 
longer period, however, if required by the applicable regulatory requirements or by the terms of 
the CSA. It is the responsibility of the Sponsor to inform the Investigator/Institution as to when 
these documents no longer need to be retained. 
Subjects’ medical files should be retained in accordance with the applicable legislation and in 
accordance with the maximum period of time permitted by the hospital, institution, or private 
practice.
