depressive disorder 
Clinical Phase/ 
Type of Trial: 
Phase 3 
Long-term trial 
Treatment 
Indication: 
Patients with major depressive disorder ("major depressive disorder, 
single episode" or "major depressive disorder, recurrent episode") 
according to the classification criteria of the Diagnostic and 
Statistical Manual of Mental Disorders, fifth edition (DSM-5®) 
Objectives: 
To assess the safety and efficacy of the long-term use of 
brexpiprazole as adjunctive therapy in combination with a 
commercially available antidepressant (selective serotonin reuptake 
inhibitor [SSRI] or serotonin-noradrenaline reuptake inhibitor [SNRI] 
for rollover subjects and SSRI, SNRI, or mirtazapine for new 
subjects) in subjects with major depressive disorder who continue 
receiving the treatment from the double-blind trial (331-102-00058) 
and in newly enrolled patients 65 years or older with major 
depressive disorder. 
Trial Design: 
A multi-center, open-label trial 
Subject 
Population: 
Target subjects will be those continuing on from the double-blind 
trial (331-102-00058) and newly recruited patients 65 years of age or 
older whose condition corresponds to major depressive disorder. 
The target number of subjects to complete 52 weeks of 
administration was set at 100 subjects and the sample size needed to 
assess the safety of brexpiprazole in the elderly was set as 30 subjects 
receiving IMP administration.

Treatment period 
1) Drugs, doses, and regimens: 
• Commercially available antidepressant 
For rollover subjects, an antidepressant (SSRI or SNRI) used 
in the double-blind trial (331-102-00058) will continue to be 
used throughout the treatment period, with no changes from 
the final dose and regimen. For new subjects, an 
antidepressant (SSRI, SNRI, or mirtazapine) being used at the 
time of informed consent will continue to be used throughout 
the treatment period, with no changes from the dose and 
regimen at the time of informed consent. 
During the treatment period, dose adjustment within the 
approved dose range is allowed according to the judgement of 
the investigator or subinvestigator, but the dose may not be 
altered at the time of dose escalation of brexpiprazole at 
Week 1. 
• Brexpiprazole 
Administration of brexpiprazole will commence at 1 mg/day 
and subjects will continue to receive a single brexpiprazole 
1 mg tablet once daily by the oral route until the observations, 
examinations, and evaluations at Week 1. Following the 
observations, examinations, and evaluations performed at 
Week 1, subjects will be administered a single brexpiprazole 
2 mg tablet once daily by the oral route. Subjects who cannot 
tolerate doses of 2 mg/day will be withdrawn from the trial.

Rationale for target number of subjects 
To verify the safety of long-term administration, the target number of 
subjects to complete 52 weeks of administration was set at around 
100 subjects. Due to the availability of data on safety in elderly 
subjects from foreign clinical trials, the sample size needed to assess 
the safety of brexpiprazole in the elderly was set as 30 new subjects 
(elderly subjects of age 65 and above) receiving IMP administration.

Introduction 
Depression is a condition that often takes a chronic course, causing significant suffering 
and imposing a burden on the patient. The disease interferes with the daily activities and 
social life of patients, who continue to suffer from decreased social functioning unless the 
disease remits.1 Moreover, depression is one of the major risk factors for suicide and, 
according to a psychological autopsy study, 60% to 70% of those who committed suicide 
had been diagnosed with depression.2 The number of suicides in Japan, even though a 
downward trend has been noted since 2012, was 21897 in 2016,3 which is still high 
compared with other developed countries. According to a published report by the 
Ministry of Health, Labour and Welfare (MHLW), the economic loss from depression 
resulting in leaves of absence from work, loss of employment, or suicide, etc, is estimated 
to be approximately 2.7 trillion yen in 2009.4 Decreased social functioning and increased 
suicide rate attributable to depression have become serious social problems. Under this 
circumstance, treatment of depression plays an important role in society. 
The lifetime and 12-month prevalence of major depressive disorder in Japan were 6.2% 
and 2.1%, respectively, according to “Study on Mental Health Epidemiological Survey,” 
a study supported by the Health and Labour Sciences Research Grants from fiscal year 
2004 to 2006.5 The Treatment Guidelines issued by the Japanese Society of Mood 
Disorders (JSMD) (hereinafter referred to as JSMD Treatment Guidelines)6 list 
pharmacotherapy with antidepressants as the mainstay in the treatment of major 
depressive disorder. As first-line agents, the guidelines recommend the following novel 
antidepressants: selective serotonin reuptake inhibitors (SSRIs), serotonin-noradrenaline 
reuptake inhibitors (SNRIs), and mirtazapine, a noradrenergic and specific serotonergic 
antidepressant. However, remission rates in patients treated with these antidepressants are 
as low as 30% to 40%.7 This difficulty in improving or achieving remission of major 
depressive disorder symptoms interferes with social functioning, causing various issues 
including loss of employment, withdrawal from education, and divorce. 
In the JSMD Treatment Guidelines,6 the following therapeutic methods are 
recommended for patients who fail to respond to the initial treatment with first-line 
agents such as SSRIs, SNRIs, and mirtazapine: Increase the dose to a sufficient level 
within the range in which adverse reactions are not clinically problematic; treat at the 
sufficiently increased dose for approximately 4 weeks; and then either change the drug if 
the patient does not respond to the treatment, or perform augmentation therapy if 
improvement is noted only in some of the symptoms of depression. Agents used for 
augmentation therapy include lithium, triiodothyronine/levothyroxine combination 


Protocol 331-102-00059

Protocol Version 3.0, 23 Jan 2020 
(T3/T4), lamotrigine, valproic acid, carbamazepine, and atypical antipsychotics. While 
augmentation therapy with lithium has been reported to potentiate the antidepressant 
effects of drugs in many placebo-controlled studies,8 most of the drugs investigated in 
such studies were tricyclic antidepressants. Therefore, little data are available on 
augmentation of SSRIs or SNRIs at present. As a result of a meta-analysis on lithium 
toxicity profile,9 renal impairment, hypothyroidism, increased blood calcium level, and 
hyperparathyroidism were reported as adverse effects of particular concern. Special 
attention should be paid to the occurrence of these adverse effects during treatment with 
lithium. Concerning augmentation therapy with T3/T4, most of the available data are also 
from studies on tricyclic antidepressants. Furthermore, the efficacy of augmentation 
therapy with lamotrigine, valproic acid, or carbamazepine has not been sufficiently 
investigated. In addition, augmentation therapy with lithium, T3/T4, lamotrigine, valproic 
acid, or carbamazepine has not been approved for the indication of depression. 
Meanwhile, concerning augmentation therapy with atypical antipsychotics mediated by 
the dopaminergic system, aripiprazole is the only antipsychotic agent that has been 
approved in Japan for use as an adjunctive therapy for the treatment of major depressive 
disorder. The efficacy of aripiprazole was confirmed in a Japanese double-blind, placebo-
controlled trial (031-08-001)10 and 3 overseas double-blind trials of aripiprazole.11,12,13 
However, the results of these clinical trials suggest that a certain percentage of patients 
cannot tolerate long-term use of aripiprazole as adjunctive therapy due to adverse events 
(AEs) such as akathisia and insomnia. This drawback of aripiprazole as an adjunctive 
therapy remains a therapeutic issue. 
Brexpiprazole is a new chemical entity discovered by Otsuka Pharmaceutical Co., Ltd. 
Unlike aripiprazole, brexpiprazole, even at a low level of < 1 nM, exhibits serotonin (5-
HT)1A receptor partial agonist activity, 5-HT2A receptor antagonist activity, and 
dopamine D2 receptor (D2 receptor) partial agonist activity with optimal intrinsic activity. 
The pharmacology of brexpiprazole is believed to be mediated by a combination of high 
binding affinity and functional activities at multiple monoaminergic receptors. It 
modulates the serotonergic and dopaminergic systems with its partial agonist activity or 
antagonist activity. In addition, for adrenergic α1B/2C receptors, it also has similar 
subnanomolar binding affinity and antagonist activity. These 5-HT1A/D2 receptor partial 
agonist activities and 5-HT2A and α1B/2C receptor antagonist activities of brexpiprazole 
are thought to contribute to the antipsychotic, antidepressant, and impulse-control effects. 
Having the optimal intrinsic activity for D2 receptors and potent effects on the 
serotonergic system compared with aripiprazole, brexpiprazole is expected to contribute 


Protocol 331-102-00059

25 
Protocol Version 3.0, 23 Jan 2020 
to a reduction in the incidence and severity of adverse reactions, such as akathisia and 
insomnia, which are issues associated with treatment using aripiprazole. 
In Japan, brexpiprazole was investigated in a double-blind, placebo-controlled trial in 
patients with an acute relapse of schizophrenia (331-10-002)14 and in a long-term trial in 
outpatients with schizophrenia (331-10-003).15 Based on the results of these trials as well 
as overseas clinical trials, an application was filed for marketing authorization of 
brexpiprazole for the indication of schizophrenia, which was approved in January 2018.16 
Outside Japan, double-blind, placebo-controlled trials in patients with an acute relapse of 
schizophrenia (331-10-230 and 331-10-231) were performed, and the results confirmed 
the efficacy of brexpiprazole and demonstrated its safety.17,18 In addition, double-blind, 
placebo-controlled trials in patients with major depressive disorder who had insufficient 
responses to SSRIs or SNRIs (331-10-227 and 331-10-228) were performed, and the 
results confirmed the efficacy of brexpiprazole as adjunctive treatment and demonstrated 
its safety in this patient population.19,20 Based on the results of the above clinical trials, 
brexpiprazole was approved in the US not only for the indication of schizophrenia but 
also received approval as adjunctive treatment of major depressive disorder.21 
As shown above, outside Japan, the efficacy of brexpiprazole was demonstrated not only 
in treating schizophrenia but also as adjunctive treatment for major depressive disorder. 
Therefore, brexpiprazole as adjunctive therapy is also likely to be effective in Japanese 
patients with inadequate response to antidepressants. The results of overseas clinical trials 
show that there are no safety-related concerns associated with brexpiprazole as adjunctive 
therapy. Therefore, use of brexpiprazole as adjunctive therapy is expected to reduce the 
incidence of adverse reactions such as akathisia and insomnia, which are issues 
associated with augmentation therapy using aripiprazole, and to enhance treatment 
adherence. 
In conclusion, since brexpiprazole adjunctive therapy may also benefit Japanese patients 
with inadequate response to antidepressants, a placebo-controlled efficacy trial (331-102-
00058) has been planned. Considering that major depressive disorder requires long-term 
treatment including pharmacotherapy, we have decided to conduct this trial to evaluate 
the long-term safety and efficacy of brexpiprazole. 
1.1 
Nonclinical Data 
Brexpiprazole has been investigated in a number of pharmacological studies for its 
efficacy as a potential treatment for schizophrenia, major depressive disorder, cognitive 
impairments, and other psychiatric disorders.

In predictive animal models for antipsychotic-like efficacy, brexpiprazole inhibited 
apomorphine-induced hyperlocomotion and stereotyped behavior, and conditioned 
avoidance response in rats, and these effects were more potent than those of aripiprazole. 
Furthermore, brexpiprazole showed dose-dependently inhibited (±)-2,5-dimethoxy-4-
iodoamphetamine (DOI)-induced head twitch response in rats, suggesting 5-HT2A 
receptor antagonism, and the effect was stronger than that of aripiprazole. Moreover, 
despite it having a lower intrinsic activity for D2 receptors and higher antipsychotic 
potency than aripiprazole, the liability for catalepsy of brexpiprazole was comparable 
with that of aripiprazole, but less than that for haloperidol, olanzapine, and risperidone, 
suggesting brexpiprazole has a low potential to induce extrapyramidal symptoms. In 
other in vivo studies, it was demonstrated that brexpiprazole is a D2 receptor partial 
agonist in rats consistent with findings in the in vitro functional assays. 
Behavioral studies were also conducted to evaluate brexpiprazole as adjunct treatment to 
antidepressants in rodent models of depression-like (forced swim test and chronic mild 
stress model) and anxiety-like (marble burying) activity. In the forced swim test 
(behavioral despair), the administration of brexpiprazole either intraperitoneally (IP) at a 
very low dose (0.001 or 0.003 mg/kg) in mice or orally at a dose of (3 mg/kg) in rats, 
significantly reduced immobility time in adjunct treatment with SSRI (paroxetine: 
p < 0.05; sertraline: p < 0.001; fluoxetine: p < 0.001; escitalopram: p < 0.05; 
fluvoxamine: p < 0.01) or SNRI (duloxetine: p < 0.05; venlafaxine: p < 0.05; 
desvenlafaxine: p < 0.001; milnacipran: p < 0.05), whereas each compound alone was 
ineffective at the dose used in this test. In a chronic mild stress model in mice, adjunct 
administration of brexpiprazole (0.03 and 0.1 mg/kg, oral, twice daily) further enhanced 
the effect of fluoxetine alone (10 mg/kg, IP) on coat state score, and significantly 
improved the nest building during 5 hours while fluoxetine alone was not effective on 
this behavior. In the marble burying test, co-administration of brexpiprazole (0.1 mg/kg, 
oral) with paroxetine, sertraline, fluoxetine, or fluvoxamine (10 or 15 mg/kg, oral), 
enhanced the reduction in marble-burying (anxiolytic-like activity) seen with each SSRI 
alone. These studies strongly suggested that brexpiprazole has good potential as adjunct 
treatment for anti-depressant therapy. 
These results suggest that, in addition to schizophrenia, brexpiprazole also has excellent 
therapeutic effect against major depressive disorder.

1.2.1.1 
Dose-finding Trial in Subjects With Schizophrenia (331-10-002) 
A double-blind, placebo-controlled trial was conducted in Japan to assess the efficacy 
and safety of fixed-dose brexpiprazole in adult subjects with an acute relapse of 
schizophrenia. This trial had a total of 4 groups consisting of a placebo group and 3 
fixed-dose groups of brexpiprazole (1, 2, and 4 mg/day). The change from baseline to 
Week 6 in the Positive and Negative Syndrome Scale (PANSS) total score, the primary 
endpoint, showed significant improvement in the 2-mg group compared with the placebo 
group (least square mean difference [LSMD]: −7.32, p = 0.0124). Although there was no 
significant difference between the 4-mg group and the placebo group, improvement in the 
PANSS total score was numerically greater in the 4-mg group than in the placebo group 
(LSMD: −3.86, p = 0.1959). There was no significant difference between the 1-mg group 
and the placebo group (LSMD = −0.63). 
The efficacy of brexpiprazole at a dose of 2 mg was demonstrated in subjects with an 
acute relapse of schizophrenia. 
The incidence of AEs was 70.4% in the 1-mg group, 69.3% in the 2-mg group, 65.5% in 
the 4-mg group, and 76.7% in the placebo group. Adverse events reported in any of the 
brexpiprazole groups at an incidence of ≥ 5% and at more than double the incidence in 
the placebo group were vomiting, blood prolactin increased, diarrhoea, nausea, and dental 
caries. There was no evident relationship between the dose of brexpiprazole and the 
incidence of AEs. Most AEs reported in brexpiprazole groups were mild or moderate in 
severity. One subject in the 4-mg group died. The AE resulting in death was asphyxia. 
This event was considered unrelated to the investigational medicinal product (IMP). The 
incidence of serious adverse events (SAEs) including death was 7.0% in the 1-mg group, 
4.4% in the 2-mg group, 4.4% in the 4-mg group, and 4.3% in the placebo group. In any 
treatment group, schizophrenia was the only SAE that occurred in more than 1 subject. 
The incidence of AEs leading to discontinuation was 16.5% in the 1-mg group, 10.5% in 
the 2-mg group, 15.0% in the 4-mg group, and 17.2% in the placebo group. The most 
frequently reported AE leading to discontinuation was schizophrenia in any treatment 
group. No marked changes were noted in laboratory test values, vital signs, body weight, 
or electrocardiogram (ECG) in brexpiprazole groups.

Long-term Trial in Subjects With Schizophrenia (331-10-003) 
This long-term trial conducted in Japan was an open-label trial to evaluate the safety and 
efficacy of long-term administration of brexpiprazole in subjects with schizophrenia, 
either continuing treatment from the dose-finding trial 331-10-002 (rollover subjects) or 
newly enrolled in this trial. 
The incidence of AEs was 85.2% in newly enrolled subjects, 80.6% in rollover subjects, 
and 83.6% in all subjects. The most frequently reported AE was nasopharyngitis (25.1%) 
in newly enrolled subjects, schizophrenia (26.5%) in rollover subjects, and 
nasopharyngitis (23.1%) in all subjects. Most AEs were mild or moderate in severity. No 
deaths were reported. The incidence of SAEs was 10.4% in newly enrolled subjects, 
18.4% in rollover subjects, and 13.2% in all subjects. Serious adverse events reported in 
more than 1 subject were schizophrenia in newly enrolled and rollover subjects and 
dehydration, akathisia, and schizophrenia in all subjects. The incidence of AEs leading to 
discontinuation was 10.9% in newly enrolled subjects, 23.5% in rollover subjects, and 
15.3% in all subjects. The most frequently reported AE leading to discontinuation was 
schizophrenia in newly enrolled subjects, rollover subjects, and all subjects. No clinically 
meaningful changes were noted in laboratory test values, vital signs, or ECGs in newly 
enrolled subjects, rollover subjects, or all subjects. The mean change in body weight from 
baseline to the final assessment was 0.34 kg in newly enrolled subjects, 2.02 kg in 
rollover subjects, and 0.93 kg in all subjects. There was no marked difference in safety 
findings between newly enrolled subjects and rollover subjects, indicating that 
switchover to brexpiprazole monotherapy from prior treatment with existing 
antipsychotic drugs has no significant impact on safety. 
All efficacy endpoints, including the PANSS total score and Clinical Global Impression - 
Severity of Illness (CGI-S) scores, remained stable until Week 52.

Confirmatory Trial in Subjects With Major Depressive Disorder 
(331-10-227) 
A double-blind, placebo-controlled trial was conducted outside Japan to evaluate the 
efficacy, safety, and tolerability of fixed doses of brexpiprazole in subjects with major 
depressive disorder who had an insufficient response to antidepressant therapy. All 
eligible subjects who passed the screening test entered an 8-week antidepressant 
treatment period (Phase A) in which SSRI/SNRI and placebo were administered in a 
single-blind manner. Subjects who responded to SSRI/SNRI and placebo in Phase A 


Protocol 331-102-00059

29 
Protocol Version 3.0, 23 Jan 2020 
entered a 6-week antidepressant-responder treatment-continuation period (Phase A+) in 
which SSRI/SNRI and placebo continued to be concomitantly administered for another 6 
weeks. Subjects who had an insufficient response to SSRI/SNRI and placebo in Phase A 
entered a double-blind period (Phase B) in which brexpiprazole or placebo was 
administered concomitantly with SSRI/SNRI for 6 weeks in a double-blind manner. This 
trial had a total of 3 treatment groups consisting of a placebo group and 2 fixed-dose 
groups of brexpiprazole (1 and 3 mg/day). The change from baseline to Week 6 in the 
Montgomery Åsberg Depression Rating Scale (MADRS) total score, the primary 
endpoint, showed numerical improvement in the 3-mg group compared with the placebo 
group (LSMD: −1.52, p = 0.0327). Improvement in the MADRS total score was 
numerically greater in the 1-mg group than in the placebo group (LSMD: −1.19, 
p = 0.0925). In the efficacy data from a subgroup meeting the inclusion criteria revised 
during the trial, the change from baseline to Week 6 in the MADRS total score showed 
improvement in the 3-mg group compared with the placebo group (LSMD: −1.95, p = 
0.0079). Meanwhile, the change from baseline in the 1-mg group was −1.30 (p = 0.0737). 
The incidence of AEs was 54.9% in the brexpiprazole 1-mg group, 63.3% in the 3-mg 
group, and 46.8% in the placebo group. The AEs reported in the brexpiprazole 3-mg 
group at an incidence of ≥ 5% and at more than double the incidence in the placebo group 
were akathisia (13.5% in the 3-mg group and 2.3% in the placebo group; hereinafter, the 
same order shall apply), somnolence (5.7%, 0.5%), and weight increased (5.7%, 0.9%). 
The AEs reported in the brexpiprazole 1-mg group at an incidence of ≥ 5% and at more 
than double the incidence in the placebo group were weight increased (6.6% in the 1-mg 
group and 0.9% in the placebo group; hereinafter, the same order shall apply) and 
nasopharyngitis (6.6%, 1.8%). Most AEs in either of the brexpiprazole groups were mild 
or moderate in severity. The incidence of SAEs was 0.4% in the 1-mg group, 0.4% in the 
3-mg group, and 0.0% in the placebo group. The incidence of AEs leading to 
discontinuation was 1.3% in the 1-mg group, 3.5% in the 3-mg group, and 1.4% in the 
placebo group. The incidences of both SAEs and AEs leading to discontinuation were 
low in the brexpiprazole groups as in the placebo group. No marked changes were noted 
in laboratory test values, vital signs, or ECGs in either of the brexpiprazole groups. 
1.2.2.2 
Confirmatory Trial in Subjects With Major Depressive Disorder

placebo group and a brexpiprazole 2-mg group. The change from baseline to Week 6 in 
the MADRS total score, the primary endpoint, showed significant improvement in the 2-
mg group compared with the placebo group (LSMD: −3.12, p = 0.0001). In the efficacy 
data from a subgroup meeting the inclusion criteria revised during the trial, the change 
from baseline to Week 6 in the MADRS total score showed improvement in the 2-mg 
group compared with the placebo group (LSMD: −3.21, p = 0.0002). 
The incidence of AEs was 59.0% in the brexpiprazole 2-mg group and 46.6% in the 
placebo group. The AEs reported in the brexpiprazole 2-mg group at an incidence of 
≥ 5% and at more than double the incidence in the placebo group were weight increased 
(8.0% in the 2-mg group and 3.1% in the placebo group; hereinafter, the same order shall 
apply) and akathisia (7.4%, 1.0%). Most AEs in the brexpiprazole group or the placebo 
group were mild or moderate in severity. The incidence of SAEs was 1.1% in the 2-mg 
group and 1.0% in the placebo group. The incidence of AEs leading to discontinuation 
was 3.2% in the 2-mg group and 0.0% in the placebo group. The incidences of both SAEs 
and AEs leading to discontinuation were low in the brexpiprazole group as in the placebo 
group. No marked changes were noted in laboratory test values, vital signs, or ECGs in 
the brexpiprazole group. 
1.2.2.3 
Confirmatory Trial in Subjects With Major Depressive Disorder 
(331-13-214) 
A double-blind, placebo-controlled trial was conducted outside Japan to evaluate the 
efficacy, safety, and tolerability of a fixed dose of brexpiprazole in subjects with major 
depressive disorder who had an inadequate response to antidepressant therapy. The trial 
was designed similarly to Trials 331-10-227 and 331-10-228 and had 2 treatment groups 
consisting of a placebo group and a brexpiprazole 2-mg group. The change from baseline 
to Week 6 in the MADRS total score, the primary endpoint, showed significant 
improvement in the 2-mg group compared with the placebo group (LSMD: −2.30, 
p = 0.0074). 
The incidence of AEs was 59.9% in the brexpiprazole 2-mg group and 49.5% in the 
placebo group. The AEs reported in the brexpiprazole 2-mg group at an incidence of 
≥ 5% and at more than double the incidence in the placebo group were restlessness (8.3% 
in the 2-mg group and 2.0% in the placebo group; hereinafter, the same order shall apply) 
and weight increased (5.2%, 0.5%). The AEs reported in the 2-mg group at an incidence 
of ≥ 5% and at a higher incidence than that in the placebo group were only akathisia 
(8.3%, 5.0%) and upper respiratory tract infection (5.2%, 5.0%). Most AEs in the 
brexpiprazole group were mild or moderate in severity. The incidence of SAEs was 0.5% 
in the 2-mg group and 0.0% in the placebo group. The incidence of AEs leading to

discontinuation was 2.1% in the 2-mg group and 0.5% in the placebo group. The 
incidences of both SAEs and AEs leading to discontinuation were low in the 
brexpiprazole group as in the placebo group. No marked changes were noted in 
laboratory test values, vital signs, or ECGs in the brexpiprazole group. 
1.2.2.4 
Long-term Trial in Subjects With Major Depressive Disorder 
(331-10-238) 
This overseas long-term open-label trial evaluated the long-term safety, tolerability, and 
efficacy of brexpiprazole in subjects with major depressive disorder who had participated 
in one of the previous phase 3 double-blind brexpiprazole trials (331-10-227, 331-10-228, 
and 331-12-282) and who remained on medication. 
The incidence of AEs was 72.3%. 
AEs with an incidence of ≥ 5% were fatigue (6.1%), viral upper respiratory tract infection 
(5.4%), weight increased (17.7%), increased appetite (6.3%), akathisia (6.7%), headache 
(7.2%), somnolence (8.0%), anxiety (5.2%), and insomnia (6.3%). 
Most AEs were mild or moderate in severity. Four deaths (0.1%) were reported. One 
death (completed suicide) was considered potentially related to the IMP and the 3 other 
deaths (gastric ulcer perforation and peritonitis, completed suicide, pulmonary embolism) 
were considered unrelated to the IMP. The incidence of SAEs was 2.4%, with depression 
(0.3%) being the most frequently reported SAE. The incidence of AEs leading to 
discontinuation was 8.6%, with weight increased (2.0%) being the most frequently 
reported AE leading to discontinuation. No clinically relevant changes were noted in 
laboratory test values except for prolactin, vital signs, or ECG. 
Improvement in all efficacy endpoints, including CGI-S score, was sustained. 
1.2.2.5 
Long-term Trial in Elderly Subjects With Major Depressive 
Disorder (16160A) 
This overseas long-term open-label trial evaluated the long-term safety, tolerability, and 
efficacy of flexibly-dosed brexpiprazole in elderly subjects with major depressive 
disorder who had an inadequate response to antidepressant therapy. 
The incidence of AEs was 77.3%. AEs with an incidence of ≥ 5% were fatigue (15.2%), 
restlessness (12.9%), increased appetite (9.8%), akathisia (8.3%), weight increased 
(8.3%), anxiety (7.6%), dizziness (7.6%), tremor (6.8%), insomnia (6.1%), 
nasopharyngitis (6.1%), back pain (5.3%), and headache (5.3%). Most AEs were mild or 
moderate in severity. One death was reported. AEs with an outcome of death were acute 
myocardial infarction and myocardial rupture. Both events were considered unrelated to 
the IMP. The incidence of SAEs was 4.5% and all these SAEs occurred in only 1 subject

each. The incidence of AEs leading to discontinuation was 18.9%, with fatigue (3.0%) 
being the most frequently reported AE leading to discontinuation. No clinically relevant 
changes were noted in laboratory test values, vital signs, or ECG. 
Improvement in all efficacy endpoints, including CGI-S score, was observed. 
1.3 
Known and Potential Risks and Benefits 
Extrapyramidal symptoms, seizures, suicidality, and dyslipidemia have been assessed as 
important risks associated with the administration of brexpiprazole. The potential 
mechanism of antipsychotics causing seizures is a class effect thought to be due to a 
reduction of the seizure threshold in susceptible individuals. The occurrence of suicidal 
behavior is inherent in psychotic illnesses and mood disorders. In the schizophrenia and 
major depressive disorder populations, short-term and long-term administration of 
brexpiprazole was associated with moderate weight gain; however, weight gain did not 
contribute significantly to IMP discontinuation, and only a few subjects with marked 
weight gain demonstrated metabolic syndrome. Although not clinically significant, an 
increase in triglycerides was observed in some trials. Due to this observation and 
considerations on potential clinical consequences related to weight gain, dyslipidemia is 
considered to be an important potential risk. 
With lower intrinsic activity at the D2 receptors and more potent effects on the 
serotonergic system, which is suggested to be involved in the improvement of depressive 
symptoms, extrapyramidal symptoms, and cognitive function, compared with 
aripiprazole, evidence suggests that brexpiprazole can reduce the incidence of AEs such 
as akathisia and other extrapyramidal symptoms, nausea, vomiting, excitement, and 
irritability, and also improve symptoms of depression. In clinical trials conducted 
overseas, the incidence of AEs, such as akathisia, which are considered risk factors for 
low adherence to treatment, was confirmed to be low in patients treated with 
brexpiprazole. Therefore, brexpiprazole is likely to become a useful treatment option for 
patients with major depressive disorder who need to receive treatment over a long period 
of time. 
2 
Trial Rationale and Objectives 
2.1 
Trial Rationale 
Considering the monoamine hypothesis, one of the assumptions of the underlying 
pathophysiologic bases of depression, use of drugs that act on the serotonergic, 
noradrenergic, or dopaminergic system is regarded as the most rational approach to the 
treatment of major depressive disorder. SSRIs and SNRIs, which are commonly used to 


Protocol 331-102-00059 
Confidential - Proprietary Information 
33 
Protocol Version 3.0, 23 Jan 2020 
treat major depressive disorder, activate the serotonergic and noradrenergic systems. 
However, these drugs poorly activate the dopaminergic system with a response rate of 
50% to 60%. Mirtazapine, another first-line drug for major depressive disorder, is an 
antagonist to alpha 2 presynaptic autoreceptors and heteroreceptors, thereby increasing 
neurotransmission of serotonin and noradrenaline in the central nervous system, but it has 
no direct pharmacological effect on the dopaminergic system. Aripiprazole is the only 
antipsychotic agent that has been approved in Japan as augmentation therapy acting 
directly on the dopaminergic system. However, the drug does have some therapeutic 
issues that need to be addressed, such as akathisia and insomnia caused by its high 
intrinsic activity at the D2 receptor. Unlike aripiprazole, brexpiprazole, even at a low 
level of < 1 nM, acts on 5-HT1A receptors and 5-HT2A receptors, and acts as an agonist at 
D2 receptors with optimal intrinsic activity. Adjunct administration of brexpiprazole with 
optimal intrinsic activity to SSRI, SNRI, or mirtazapine is likely to act on not only the 
serotonergic and noradrenergic systems but also the dopaminergic system. Therefore, this 
treatment is expected to be more effective in treating major depressive disorder patients 
with a safety profile that is superior to monotherapy with an antidepressant and thereby 
improve adherence to treatment. 
Phase 3, double-blind, placebo-controlled trials of fixed doses of brexpiprazole (331-10-
227, 331-10-228, and 331-13-214) conducted outside Japan demonstrated the efficacy of 
brexpiprazole as adjunctive therapy to SSRIs or SNRIs in patients with major depressive 
disorder and found no significant safety concerns. Furthermore, in an overseas long-term 
trial in patients with major depressive disorder, 52-week brexpiprazole treatment revealed 
no significant safety concerns, and its long-term sustained effectiveness was also 
confirmed. It is expected that the long-term use of brexpiprazole as adjunctive therapy 
will also be well tolerated in Japanese patients with major depressive disorder, and that 
the effectiveness will be sustained for a longer period. Based on the above, we have 
decided to conduct this trial to assess the safety and efficacy of long-term brexpiprazole 
treatment. 
This trial will assess the long-term safety and efficacy of brexpiprazole as adjunctive 
therapy, primarily in rollover subjects from a Japanese double-blind trial (331-102-
00058). Therefore, brexpiprazole 2 mg/day, which is the dose established for the double-
blind trial (331-102-00058) and is a dose at which efficacy has been verified in multiple 
overseas clinical trials, was selected as a maintenance dose in this trial. A starting dose 
was set at brexpiprazole 1 mg/day, the same starting dose as in the double-blind trial 
(331-102-00058). The same safety and efficacy endpoints as those employed in the 
double-blind trial (331-102-00058) will also be used. In this trial, an antidepressant (any 


Protocol 331-102-00059 
Confidential - Proprietary Information 
34 
Protocol Version 3.0, 23 Jan 2020 
one of SSRIs or SNRIs) used in the double-blind trial (331-102-00058) will be 
administered with no changes in the final dose and regimen, and brexpiprazole will be 
used at a dose of 2 mg/day (starting dose: 1 mg/day) in combination with the 
antidepressant. Duration of the treatment was set at 52 weeks, based on "The Extent of 
Population Exposure to Assess Clinical Safety for Drugs Intended for Long-Term 
Treatment of Non-Life-Threatening Conditions" (PAB/PCD Notification No. 592 dated 
24 May 1995). 
As prevalence of major depressive disorder is also high in the elderly, it is probable that 
the drug will also be used for elderly patients aged 65 years or older after approval is 
obtained for its use as adjunctive therapy in major depressive disorder. Therefore, new 
subjects 65 years or older will also be involved, in view of the necessity to assess the 
long-term safety and efficacy of brexpiprazole as adjunctive therapy in elderly patients 
with major depressive disorder and based on the recommendations in "Studies in Support 
of Special Populations: Geriatrics" (PAB/NDD Notification No. 104 dated 02 Dec 1993). 
In newly enrolled subjects, an antidepressant will be used, which will be a drug that the 
subject is using at the time of informed consent, either an SSRI, SNRI, or mirtazapine. 
An overseas long-term clinical trial in patients with major depressive disorder aged 65 
years or older also demonstrated the excellent tolerability of brexpiprazole in elderly 
patients. 
The US package insert of brexpiprazole21 contains warnings regarding antidepressant-
related suicidal ideation or suicidal behavior, and also in the Japanese package insert of 
brexpiprazole, patients with a history of suicidal ideation or suicide attempt come under 
Careful Administration. Considering the above, criteria that require the exclusion or 
discontinuation of patients at high risk of suicide have been established as exclusion or 
discontinuation criteria to minimize the risk of suicide during the trial and thereby to 
ensure the safety of subjects. 
Based on the above, we conclude that assessment of the long-term safety and efficacy of 
brexpiprazole as adjunctive therapy in conjunction with commercially available 
antidepressants (SSRIs or SNRIs for rollover subjects and SSRIs, SNRIs, or mirtazapine 
for newly enrolled subjects) in Japanese patients with major depressive disorder is 
scientifically and ethically justified. 
2.2 
Rationale for DNA Storage 
This trial will involve the optional storage of DNA samples from newly enrolled subjects. 
Samples for DNA storage will be collected only from subjects who have provided written 
consent to DNA storage and only at trial sites which have agreed to sampling for DNA 


Protocol 331-102-00059 
Confidential - Proprietary Information 
35 
Protocol Version 3.0, 23 Jan 2020 
storage. Concerning collecting DNA samples during the trial period and storing them, 
MHLW states as follows in Q&A 1 in "Regarding Clinical Studies Utilizing 
Pharmacogenomics (PFSB/ELD Notification No. 0930007 dated 30 Sep 2008)": It is 
permissible to obtain samples from subjects for genomic/genetic analysis in association 
with the evaluation of the IMP (eg, pharmacokinetics, efficacy, safety) if either of the 
following 2 circumstances apply: 1) The target and time of genomic/genetic analysis are 
specified at the time of implementation of a trial; or 2) Genomic/genetic analysis in 
association with the IMP evaluation is planned to be performed in the future although the 
target or time of the analysis is not specified at the time of implementation of a trial. In 
Q&A 2, MHLW also states that it is permissible to obtain samples from subjects for 
genomic/genetic analysis which is not associated with the evaluation of the IMP. 
Based on the above, we concluded that DNA storage conducted to enable future 
exploratory investigation regarding the relationships between DNA mutations (eg, gene 
polymorphism) and therapeutic responses to brexpiprazole and/or relationships between 
DNA mutations and the onset, severity, or progression of the disease is justified. 
In this trial, rollover subjects from the double-blind trial (331-102-00058) will be 
excluded from DNA storage, because they are already the target of DNA storage in the 
previous trial. 
2.3 
Rationale for Dosing and Regimen 
2.3.1 
Rationale for Regimen 
All clinical trials of brexpiprazole in patients with major depressive disorder conducted 
outside Japan have employed once daily oral administration. This trial will likewise 
employ once daily oral administration of brexpiprazole, as the drug is approved in the US 
with this regimen and because it has been confirmed that there are no major differences 
in the pharmacokinetics of brexpiprazole between Japanese and non-Japanese 
populations. 
2.3.2 
Rationale for Dose 
2.3.2.1 
Rationale for Maintenance Dose 
Based on the efficacy of brexpiprazole at 2 mg/day confirmed in overseas clinical trials in 
patients with major depressive disorder and the similarity in the pharmacokinetics of 
brexpiprazole observed in Japanese and non-Japanese populations, a dose of 2 mg/day is 
likely to be effective in Japanese patients with major depressive disorder. A maintenance 
dose of 2 mg/day was selected for this trial to evaluate the long-term safety and efficacy 
of 2 mg/day of brexpiprazole. 


Protocol 331-102-00059

36 
Protocol Version 3.0, 23 Jan 2020 
2.3.2.2 
Rationale for a Starting Dose of 1 mg/day 
Overseas clinical trials of brexpiprazole involving patients with major depressive disorder 
employed a starting dose of 0.5 or 1 mg/day, with no great differences in safety noted 
during the dose-escalation period at either of the starting doses; therefore, a starting dose 
of 1 mg/day was selected in order to attain an effective dose swiftly. 
2.4 
Trial Objectives 
The objective of the trial is to assess the safety and efficacy of the long-term use of 
brexpiprazole as adjunctive therapy in concomitant use with a commercially available 
antidepressant (SSRI or SNRI for rollover subjects and SSRI, SNRI, or mirtazapine for 
new subjects) in subjects with major depressive disorder who continue receiving the 
treatment from the double-blind trial (331-102-00058) and in newly enrolled patients 65 
years or older with major depressive disorder.

Trial Design 
3.1 
Type/Design of Trial 
The trial is a multi-center, open-label trial to assess the safety and efficacy of the long-
term use of brexpiprazole as adjunctive therapy in conjunction with a commercially 
available antidepressant (SSRI or SNRI for rollover subjects and SSRI, SNRI, or 
mirtazapine for new subjects) at a dose and regimen specified in the package insert. 
Subjects of the trial are those who have completed the double-blind period (Phase B) of 
the double-blind trial (331-102-00058), and newly enrolled patients 65 years or older 
with major depressive disorder who have received 1 to 3 adequate antidepressant drug 
treatmentsa for major depressive episodes and have shown an inadequate responseb to all 
of these treatments. 
The trial design is shown in Figure 3.1-1. The trial comprises a screening period, 
treatment period, and post-treatment observation period. 
 
a Definition of "adequate antidepressant drug treatment" is provided below. 
Treatment with an antidepressant at an approved dose for at least 6 weeks (for 
combination therapy, treatment for at least 3 weeks) 
b Definition of "inadequate response" is provided below.

Trial Treatments 
(1) 
Drugs, dose, and regimen 
• Commercially available antidepressant 
For rollover subjects, an antidepressant (SSRI or SNRI) used in the double-blind trial 
(331-102-00058) will continue to be used throughout the treatment period, with no 
changes from the final dose and regimen. For new subjects, an antidepressant (SSRI, 
SNRI, or mirtazapine) being used at the time of informed consent will continue to be 
used throughout the treatment period, with no changes from the dose and regimen 
used at informed consent. 
During the treatment period, dose adjustment within the approved dose range is 
allowed according to the judgement of the investigator or subinvestigator, but the 
dose may not be altered at the time of dose escalation of brexpiprazole at Week 1. 
• Brexpiprazole 
Administration of brexpiprazole will commence at 1 mg/day and subjects will 
continue to receive a single brexpiprazole 1 mg tablet once daily by the oral route 
until the observations, examinations, and evaluations at Week 1. Following the 
observations, examinations, and evaluations at Week 1, subjects will be administered 
a single brexpiprazole 2 mg tablet once daily by the oral route. Subjects who cannot 
tolerate doses of 2 mg/day will be withdrawn from the trial. 
 
(2) 
Treatment period 
52 weeks 
 
[Rationale for treatment period] 
Treatment duration was set at 52 weeks with reference to "The Extent of Population 
Exposure to Assess Clinical Safety for Drugs Intended for Long-Term Treatment of Non-
Life-Threatening Conditions" (PAB/PCD Notification No. 592 dated 24 May 1995). 
3.3 
Trial Population 
Adult and elderly patients with "major depressive disorder, single episode" or "major 
depressive disorder, recurrent episode" according to the classification criteria of the 
Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) 
3.3.1 
Number of Subjects and Trial Population 
The trial will be conducted in patients who have major depressive disorder (major 
depressive disorder, single episode; major depressive disorder, recurrent episode) 
according to the DSM-5 classification. Concerning rollover subjects from the double-
blind trial (331-102-00058), their eligibility for proceeding to the long-term trial will be 


Protocol 331-102-00059 
Confidential - Proprietary Information 
39 
Protocol Version 3.0, 23 Jan 2020 
assessed, after acquisition of informed consent to the long-term trial, based on the results 
of examinations and assessments at Week 6 of the double-blind period (Phase B) of the 
double-blind trial (331-102-00058) and at baseline. The eligibility of new subjects will be 
judged after acquisition of informed consent from elderly patients 65 years or older, 
based on the results of examinations and assessments at screening and baseline. As the 
sample size needed to assess the safety and efficacy of brexpiprazole in the elderly, the 
number of subjects receiving the treatment was set at 30. 
3.3.2 
Subject Number Assignment 
Following the provision of written informed consent to participate in this trial, each 
rollover subject will continue to use the subject identifier (ID) assigned in the previous 
double-blind trial (331-102-00058), and each new subject will be assigned a unique 
subject ID (site number [3 digits] + subject number [S + 5 digits]). The site number will 
be designated by the sponsor. A subject number is a serial in-site number starting with 
S20001, , which is given to each subject in the order of provision of consent. 
3.4 
Eligibility Criteria 
3.4.1 
Informed Consent 
Written informed consent will be obtained from all subjects on their voluntary decision. 
Rollover subjects will provide written informed consent after completion of observations, 
examinations, and assessments at Week 6 in the double-blind period (Phase B) of the 
previous double-blind trial (331-102-00058). Consent will be documented on a written 
informed consent form (ICF) with the subject’s signature. The ICF will be approved by 
the same institutional review board (IRB) that approves this protocol. 
Each ICF will comply with the International Council for Harmonisation (ICH) Good 
Clinical Practice (GCP) Guideline22 and regulatory requirements. 
Investigators or subinvestigators may discuss the possibility for entry with a potential 
subject without first obtaining consent. However, informed consent must be obtained and 
documented before initiation of any procedures that are performed solely for the purpose 
of determining eligibility for this trial, including withdrawal from current medication(s). 
Potential subjects are free to refuse entry into the trial, or withdraw from the trial at any 
time, without justification, and there will be no consequences to their further care. 
Once appropriate essential information has been provided and fully explained in plain 
language to the potential subject by the investigator or subinvestigator, the IRB-approved 
written ICF will be signed and dated by both the potential subject and the person 
obtaining consent (investigator or subinvestigator). If a study collaborator has provided a 


Protocol 331-102-00059 
Confidential - Proprietary Information 
40 
Protocol Version 3.0, 23 Jan 2020 
supplemental explanation, the IRB-approved written ICF will be signed and dated by the 
study collaborator. The subject will receive a copy of the signed ICF; the original shall be 
kept on file by the investigator or subinvestigator. 
Subjects may be asked to sign additional ICFs if the protocol is amended to significantly 
add or change procedures. 
For DNA storage, a separate ICF will be used for explanation and written informed 
consent will be obtained from subjects on their voluntary decision in a similar manner. 
DNA storage is optional and refusal to allow DNA storage will not affect trial 
participation.

• Mean changes from baseline in Hamilton Rating Scale for Depression (HAM-D) 17-
item total score 
• Mean changes from baseline in mean Sheehan Disability Scale (SDS) score 
 
[Rationale] 
MADRS is used worldwide as a depression assessment scale, was created primarily to 
assess psychiatric symptoms of depression and exclude somatic symptoms, and is 
generally used in clinical trials that involve patients with major depressive disorder; 
therefore, the same endpoint will be employed in this trial also. 


Protocol 331-102-00059

Protocol Version 3.0, 23 Jan 2020 
The MADRS response rate and MADRS remission rate were selected because they are 
useful for assessing the effects of antidepressants and are used in many clinical trials 
utilizing MADRS. 
CGI-I and CGI-S were selected because they are an overall assessment that enables 
comprehensive assessment of the subject’s clinical symptoms and are used in many 
clinical trials. HAM-D was selected because it is useful for assessing a wide range of 
depressive symptoms including somatic and psychiatric symptoms and is used in many 
clinical trials. SDS was selected because it is a functional impairment assessment scale 
composed of 3 daily living function-related items (work/school, social life, and 
communication and role within in family), and enables functional assessment through 
self-assessment.

Trial Procedures 
The schedule of all examinations and assessments/observations in the screening period, 
treatment period, and post-treatment observation period is provided in Table 3.7-1. 
The investigator or subinvestigator should conduct observations, examinations, and 
evaluations in accordance with the schedules. For items that can be performed by a 
clinical trial associate, such as examination of subject demographics and clinical 
laboratory tests, a clinical trial associate can perform them under the supervision of the 
investigator.

Schedule of Assessments 
3.7.1.1 
Informed Consent 
Before all examinations, written informed consent is to be obtained from subjects. 
Rollover subjects will provide written informed consent after completion of the 
observations, examinations, and assessments at Week 6 of the preceding double-blind 
trial (331-102-00058). The procedures for progressing from the double-blind trial (331-
102-00058) are separately specified in written procedures. After acquisition of informed 
consent, subjects will be registered in the interactive web response system (IWRS). For 
rollover subjects, the same subject ID will be used as in the double-blind trial (331-102-
00058) and for new subjects a new subject ID will be assigned. Management of IWRS 
after the first registration is separately specified in written procedures, as a management 
system particularly for subject enrollment status and IMP. The investigator or 
subinvestigator will record the date on which signed inform consent was obtained in the 
subject screening log. The subject ID and date on which signed inform consent was 
obtained will also be recorded in the source documents and the case report form (CRF). 
3.7.1.2 
Screening (New Subjects Only) 
After acquisition of informed consent and within 28 days before commencement of the 
treatment period, the investigator or subinvestigator will perform the examinations and 
assessments at the screening (Table 3.7-1) and record the results in the source documents 
and CRF, and will also judge subject eligibility for trial participation. The investigator or 
subinvestigator will then record enrollment status, date of enrollment, and reasons for any 
failed enrollment in the subject screening log. 
The investigator or subinvestigator will examine the following subject demographics and 
record the results in the source documents and the CRF. Regarding the treatment history 
for the current major depressive episode, all antidepressant prior medications and their 
effectiveness, as well as psychotherapies/somatic therapies up until 6 weeks before 
informed consent will be examined. To determine their effectiveness, the results of 
evaluation will be classified as < 25% Improvement, 25% to 49% Improvement, 50% to 
< 75% Improvement, and ≥ 75% Improvement (complete recovery from depressive 
symptoms and not the slightest improvement considered as 100% and 0%, respectively), 
based on the patient’s self-evaluations.

Observations/Examinations in the Treatment Period (52 Weeks) 
The investigator or subinvestigator will judge eligibility of rollover subjects from the 
double-blind trial (331-102-00058), based on the results of examinations and assessments 
at baseline and clinical laboratory values and 12-lead ECG at Week 6 of the double-blind 
period (Phase B) of the double-blind trial (331-102-00058). The treatment period will 
commence within 28 days from Week 6 of the double-blind period (Phase B) of the 
double-blind trial (331-102-00058). If the examinations and assessments at Week 6 of the 
double-blind period (Phase B) of the double-blind trial (331-102-00058) have been 
performed within a period of 7 days prior to the day of baseline assessment (Day −7 to 
Day 0), the data will be used as baseline data for this trial. The eligibility of new subjects 
will be judged based on the results of examinations and assessments at screening and 
baseline. The result of the eligibility judgement will be registered in the IWRS and

3.7.8 
Pharmacogenomic Assessments 
3.7.8.1 
DNA Storage (for New Subjects Only) 
3.7.8.1.1 
Objective of DNA Storage 
DNA storage will be conducted to enable future exploratory investigation regarding the 
relationships between specific DNA mutations and individual differences in the efficacy, 
safety, or pharmacokinetics of brexpiprazole, and/or the relationships between specific 
DNA mutations and disease onset, severity, progression, etc. 
3.7.8.1.2 
Target Subjects of DNA Storage 
New subjects from whom written informed consent for DNA storage has been obtained 
will be included. Consent to DNA storage is voluntary. DNA storage will be conducted 
only if approved by the trial site’s IRB, etc. Informed consent for DNA storage must be 
obtained prior to blood sampling for DNA storage. 
3.7.8.1.3 
Timing of Blood Sampling 
Blood sampling will be performed at Week 4 of the treatment period (or at 
discontinuation if a subject withdraws before the Week 4 visit). If resampling of blood, if 
necessary, it will be performed during the trial period. 
3.7.8.1.4 
Handling of Samples 
All blood samples will be shipped to the DNA storage facility. The timing of blood 
sampling will be recorded in the source documents and CRF. Details regarding handling 
and shipment of samples are described in Appendix 1. DNA samples will be stored until 
the earliest of the following time points: 1) when genomic/genetic analysis is judged to be 
unnecessary, 2) when 15 years have passed since receipt of informed consent from the 
first subject, 3) when the subject withdraws consent to DNA storage. 
3.7.8.1.5 
Genomic/Genetic Analysis 
Genomic/genetic analysis will be performed only when exploratory investigation 
regarding the relationships between specific DNA mutations and individual differences in 


Protocol 331-102-00059 
Confidential - Proprietary Information 
66 
Protocol Version 3.0, 23 Jan 2020 
the efficacy, safety, or pharmacokinetics of brexpiprazole and/or the relationships 
between specific DNA mutations and disease onset, severity, progression, etc is 
considered to be useful. 
If it is decided to perform genomic/genetic analysis, a pharmacogenomic research 
protocol will be prepared and, after approval has been obtained from the sponsor’s IRB, 
the analysis will be carried out in compliance with the regulations of each country 
regarding analysis plans. 
Genes that may be targeted in genomic/genetic analysis include genes considered to be 
possibly related to individual differences in the efficacy, safety, or pharmacokinetics of 
brexpiprazole and genes considered to be possibly related to diseases; however, at present 
those genes have not yet been identified. 
A genomewide association analysis using DNA chips, microarrays, next-generation 
sequencers, etc, may also be performed for genomic/genetic analysis; however, the 
results will still only be used for the purpose of identifying genes possibly related to 
individual differences in the efficacy, safety, or pharmacokinetics of brexpiprazole and/or 
the relationships between specific DNA mutations and disease onset, severity, 
progression, etc. The results of genomic/genetic analysis will be reported to the sponsor 
by the genomic/genetic analysis facility while the samples are still double-coded. 
3.7.8.1.6 
Informed Consent for DNA Storage 
An ICF for DNA storage and genomic/genetic analysis using stored DNA will be 
prepared separately from the ICF for the trial, and written informed consent to DNA 
storage will be obtained from each subject in person. The date of informed consent will 
be recorded in the source documents and CRF. 
If the subject withdraws consent to participate in DNA storage during the DNA storage 
period, the sponsor will instruct the DNA storage facility to dispose of the subject’s DNA. 
However, withdrawal from the trial will not be considered withdrawal of consent for 
DNA storage. Upon receipt of a notification for disposal from the sponsor, the DNA 
storage facility will dispose of the DNA sample without anyone being aware of whose 
sample it is. Any results of genomic/genetic analysis obtained prior to the withdrawal of 
consent will not be disposed of. 
3.7.8.1.7 
Disclosure of Genomic/Genetic Analysis Results to Subjects 
In this trial, genomic/genetic analysis will be performed for genes considered to be 
possibly related to individual differences in the efficacy, safety, or pharmacokinetics of 
brexpiprazole, and/or genes considered to be possibly related to diseases; however, even 
if the analysis results show some relationship, such a relationship would only be 


Protocol 331-102-00059

67 
Protocol Version 3.0, 23 Jan 2020 
exploratory or at an early stage of research, and therefore its scientific reliability and 
accuracy would not have been fully confirmed. Since disclosure of information for which 
scientific evaluation has not yet been verified would be of no benefit to the subjects, the 
sponsor will not disclose the results of genomic/genetic analysis to the subjects. 
3.7.9 
End of Trial 
The end of trial date is defined as the date of last visit or contact or date of final contact 
attempt as recorded on the post-treatment follow-up page of the CRF prepared for the last 
subject completing or withdrawing from the trial. 
3.8 
Stopping Rules, Withdrawal Criteria, and Procedures 
3.8.1 
Entire Trial 
In the event of sponsor termination or suspension of the trial for any reason, prompt 
notification will be given to the heads of the trial sites and regulatory authorities in 
accordance with regulatory requirements. 
3.8.2 
Individual Site 
Individual trial site participation may be discontinued by the sponsor, the investigator, or 
the IRB for medical, safety, regulatory, ethical, or other reasons consistent with 
applicable laws, regulations, and GCP. The head of the trial site will notify the sponsor 
promptly if the trial is terminated by the investigator or the IRB at the site. 
3.8.3 
Individual Subject Discontinuation 
3.8.3.1 
Treatment Discontinuation 
After commencement of the treatment period, a subject may stop treatment permanently 
for a variety of reasons. Treatment discontinuations may be initiated by a subject who is 
no satisfied with treatment or may become medically necessary due to AEs, required 
treatment with a disallowed medication or therapy, or other issues, as determined by the 
investigator or subinvestigator. However, each investigator or subinvestigator must 
comprehensively review the circumstances and offer the subject options for continued 
treatment to the degree possible as described in Section 3.8.3.4 Procedures to Encourage 
Continued Trial Participation. 
3.8.3.2 
Documenting Reasons for Discontinuation 
All subjects have the right to withdraw and the investigator or subinvestigator can 
discontinue a subject’s participation in the trial at any time if medically necessary. In 
addition, subjects meeting the following criteria must be withdrawn from the trial. Only

68 
Protocol Version 3.0, 23 Jan 2020 
one reason for discontinuation (the main reason) can be recorded in the source documents 
and CRF, along with the date of discontinuation. 
1) Adverse event: 
a) Death 
b) Subjects experiences exacerbation of symptoms of the underlying disease, and 
the investigator or subinvestigator judges that continued participation in the 
trial is inappropriate 
c) Subject experiences a change to the manic state 
d) Based on clinical symptoms, subject is considered to be at high risk of suicide 
in the opinion of the investigator or subinvestigator or has an MADRS score 
for Suicidal Thought (No. 10) of ≥ 5 or HAM-D suicide score (No. 11) of ≥ 3, 
or those answering "Yes" to question 4 or 5 of C-SSRS. 
e) Subject decides to discontinue because of annoyance or discomfort due to a 
nonserious AE which is not otherwise determined to be an undue hazard 
f) Continuation of IMP would place the subject at undue risk as determined by 
the investigator or subinvestigator (eg, there is a safety concern possibly, 
probably, or likely related to IMP) 
i) SAE 
ii) Other safety concern or AE possibly, probably, or likely related to IMP 
2) Subject’s withdrawal of informed consent 
a) Reasons unrelated to medical condition (issues regarding subject’s 
convenience, such as a change of residence or other commitments: provide 
detail and review AE history with subject) 
b) Withdrawal of informed consent (complete written withdrawal of consent 
form) 
3) Marked noncompliance with the IMP regimen 
a) Compliance rate of < 65% during the interval between 2 consecutive 
scheduled visits 
4) Protocol deviation 
a) Subject is discovered to have not been in accord with inclusion/exclusion 
criteria 
b) Subject has received any prohibited concomitant drugs or therapies, or is 
judged to be in need of such 
c) Subject can no longer be administered antidepressant (SSRI or SNRI for 
rollover subjects and SSRI, SNRI, or mirtazapine for new subjects) 
5) Lost to follow-up 
6) Pregnancy (see Section 5.5 Pregnancy) 
7) Termination of all or part of the trial by the sponsor 
8) Discontinuation of the trial site by the sponsor 
9) Lack of efficacy

10) Impossibility of protocol compliance or judgement by the investigator or 
subinvestigator that discontinuation is necessary for any reason other than the 
above 
If the subject discontinues IMP due to an AE, the investigator, subinvestigator, or other 
trial personnel will make every effort to follow the event until the event is resolved or 
stabilized, or the subject is lost to follow up or has died. Follow-up procedures in Section 
3.8.3.1 Treatment Discontinuation must be followed. 
3.8.3.3 
Withdrawal of Consent 
All subjects have the right to withdraw their consent from further participation in the trial 
at any time without prejudice. Subjects cannot withdraw consent for use of data already 
collected as part of the trial, but only for future participation. The investigator or 
subinvestigator can also discontinue a subject’s participation in the trial at any time if 
medically necessary. Unless the subject provides their written withdrawal of consent or 
there is other written documentation by the investigator or subinvestigator confirming the 
subject’s verbal intent to completely withdraw from the trial, subjects should be followed 
for all protocol-specified evaluations and assessments, if possible. 
Complete withdrawal of consent requires refusal by a subject of ALL of the following 
methods of follow up (these methods of follow up will also be noted in the trial ICF): 
• Participation in all follow-up procedures specified in the protocol (whether in-clinic, 
by telephone, or by an in-home visit). 
• Participation in a subset of protocol specified follow-up procedures (by a frequency 
schedule and method, as agreed by subject and staff). 
• Contact of the subject by trial personnel, even if only by telephone, to assess current 
medical condition, and obtain necessary medical or laboratory reports relevant to the 
trial’s objectives. 
• Contact of alternative person(s) who have been designated in source documents as 
being available to discuss the subject’s medical condition, even if only by telephone, 
mail, or e-mail (eg, family, spouse, partner, legal representative, friend, neighbor, or 
physician). 
• Access to medical information from alternative sources (eg, hospital/clinic medical 
records, referring doctor’s notes, public records, dialysis, transplantation or vital 
registries, social media sources). 
Withdrawal of consent is a critical trial event and therefore should be approached with 
the same degree of importance and care as is used in initially obtaining informed consent. 
The reasons of a subject for an intended withdrawal need to be completely understood, 
documented, and managed to protect the rights of the subject and the integrity of the trial. 
A subject may initially express their desire to discontinue IMP administration, which is 
not equivalent to a complete withdrawal of consent for further participation (see Section 


Protocol 331-102-00059

70 
Protocol Version 3.0, 23 Jan 2020 
3.8.3.1 Treatment Discontinuation). A subject may, however, indicate that further trial 
participation is creating a burden on their work or social schedule. Therefore, the 
investigator or subinvestigator should follow the procedures outlined in Section 3.8.3.2 
Documenting Reasons for Discontinuation to determine if the subject can continue 
participation in the trial if modifications to his/her treatment and/or schedule of 
assessments can be accommodated. Only subjects who withdraw their permission for all 
of the above degrees of follow-up are considered to have completely withdrawn their 
consent to participate in the trial. 
3.8.3.4 
Procedures to Encourage Continued Trial Participation 
In all cases of impending IMP discontinuation or consent withdrawal, investigators or 
subinvestigators will be given instructions to meet and discuss with the subject their 
options of continuing in the trial, preferably on therapy. The investigator or 
subinvestigator should ensure understanding and documentation of the reasons why the 
subject wishes to withdraw consent. 
3.9 
Screen Failures 
A screen failure subject is one from whom informed consent is obtained and is 
documented in writing (ie, subject has signed an ICF), but who is not enrolled in the 
treatment period of the trial. For screen failures, the following information will be 
recorded in the source documents and the CRF. 
• Date of visit 
• Date of informed consent 
• Subject demographics 
− Date of investigation 
− Date of birth 
− Sex 
− Race 
− Ethnicity 
− Country where trial is performed 
• Results of eligibility criteria assessment 
• Date of assessment as screen failure 
• Reason for screen failure 
New subjects who participate in this trial but who are categorized as screening failures 
are permitted to be rescreened. Prior to rescreening, if performed, informed consent must 
be newly obtained and a new subject ID must be assigned.

Protocol Version 3.0, 23 Jan 2020 
3.10 
Definition of Completed Subjects 
The treatment period is defined as the time period during which subjects are evaluated for 
safety and efficacy irrespective of whether the subject actually received all doses of the 
IMP. Subjects who are evaluated at the last scheduled visit during the treatment period 
will be defined as trial completers. For the purposes of this trial, subjects who are 
evaluated at Week 52 of the treatment period will be defined as trial completers. 
3.11 
Definition of Subjects Lost to Follow-up 
Subjects who cannot be contacted on or before the examinations at Week 52 of the 
treatment period, who do not have a known reason for discontinuation (eg, withdrew 
consent or AE), and for whom a survival status at the end of the trial cannot be 
determined will be classified as “lost to follow-up.” Subjects who did not undergo post-
treatment observation will also be classified as “lost to follow-up.” Survival status can be 
determined from a variety of sources, either by obtaining acceptable documentation for 
death (ie, death certificate, medical records, public records, statement by a family 
member or primary care physician) or acceptable documentation for life (ie, direct 
contact with the subject, medical records, successful telephone contact with the subject, 
statement by a family member or primary care physician, or public records). 
The investigator, subinvestigator, or designee will make 3 documented attempts to 
contact the subject by telephone and in the event the site is unable to reach the subject by 
telephone, the site will attempt to contact the subject via certified mail or an alternative 
similar method where appropriate, before assigning a “lost to follow-up” status, and will 
make a record of the inability to contact the subject, recording the dates of the 3 attempts 
at contact and the method(s) of contact in the source documents and the date and method 
of the last attempt at contact in the CRF. 
3.12 
Subject Compliance 
The investigator or subinvestigator will give subjects the following instructions to ensure 
their compliance with the protocol. 
1) Site visits are to be made on the scheduled visit days as specified in the protocol 
(see Section 3.7.1.6). 
2) No prohibited concomitant drugs are to be taken during the period from informed 
consent to Week 52 of the treatment period (or discontinuation). 
3) No commercially available brexpiprazole is to be taken during the period from the 
assessment at Week 52 of the treatment period (or discontinuation) to the end of 
the post-treatment observation period. 


Protocol 331-102-00059 
Confidential - Proprietary Information 
72 
Protocol Version 3.0, 23 Jan 2020 
4) The requirements regarding the method, duration, and frequency of administration 
of a commercially available antidepressant and the IMP are to be complied with 
(see Section 3.2). If the IMP compliance during the interval between 2 
consecutive scheduled visits is less than 65%, the subject will be withdrawn from 
the trial (see Section 3.8.3). 
5) Subjects must take appropriate contraceptive measures as instructed (see 
Section 5.5). 
 
3.13 
Protocol Deviations 
In the event of a significant deviation from the protocol due to an emergency, accident, or 
mistake (eg, violation of informed consent process, IMP dispensing or subject dosing 
error, treatment assignment error, subject enrolled in violation of eligibility criteria or 
concomitant therapy criteria), the investigator, subinvestigator, or designee will contact 
the sponsor at the earliest possible time by telephone. The investigator or subinvestigator 
and sponsor will come as quickly as possible to a joint decision regarding the subject’s 
continuation in the trial. This decision will be documented by the investigator or 
subinvestigator and the sponsor, and reviewed by the site monitor. For major deviations, 
the date on which the deviation occurred and the details of the deviation will be recorded 
in the source documents and the CRF.

necessary in the opinion of the investigator or subinvestigator, only one drug can be 
coadministered with no prophylactic use allowed. Change in the types of the 
aforementioned drugs is allowed. 
• Antipyretic analgesic anti-inflammatory drugs, antihistamines 
Concomitant use is allowed if subjects were already using the drugs at the time of 
informed consent to treat complications; however, no changes in dose and regimen 
are allowed unless AEs occur or the use of these drugs is considered unnecessary 
because of remission of symptoms. Furthermore, short-term concomitant use, 
including use as a medication for colds during the treatment period, is also allowed. 
The topical external use of these drugs is allowed. 
Note: Caution should be exercised to avoid concomitant use of CYP2D6 inhibitors, 
CYP3A4 inhibitors, and CYP3A4 inducers specified in Section 4.4 Other Restrictions 
(eg, chlorpheniramine, diphenhydramine, clemastine, and celecoxib).

Reporting of Adverse Events 
5.1 
Definitions 
An AE is defined as any untoward medical occurrence in a patient or clinical trial subject 
administered a medicinal product and which does not necessarily have a causal 
relationship with this treatment. Adverse events would not include information recorded 
as complications at screening (for new subjects) or baseline (for rollover subjects) for 
preplanned procedures for which the underlying condition was known and no worsening 
occurred. For rollover subjects, AEs that occurred during the double-blind trial (331-102-
00058) and persist without recovery or resolution, but have not become exacerbated, will 
not be counted as AEs occurring in this trial. An adverse drug reaction is any untoward 
and unintended response to an IMP related to any dose administered. 
A suspected adverse reaction is any AE for which there is a reasonable possibility that the 
IMP caused the AE. 
 
An SAE includes any event that results in any of the following outcomes: 
• Death 
• Life-threatening; ie, the subject was, in the opinion of the investigator, or 
subinvestigator at immediate risk of death from the event as it occurred. It does not 
include an event that, had it occurred in a more severe form, might have caused death. 
• Persistent or significant incapacity/disability or substantial disruption of the ability to 
conduct normal life functions. 
• Requires inpatient hospitalization or prolongs hospitalization 
− Hospitalization itself should not be reported as an SAE; whenever possible the 
reason for the hospitalization should be reported. 
− Hospitalizations or prolonged hospitalizations for social admissions (ie, those 
required for reasons of convenience or other nonmedical need) are not considered 
SAEs. 
• Congenital anomaly/birth defect. 
• Other medically significant events that, based upon appropriate medical judgment, 
may jeopardize the subject and may require medical or surgical intervention to 
prevent one of the outcomes listed above, eg, allergic bronchospasm requiring 
intensive treatment in an emergency room or home, blood dyscrasias or convulsions 
that do not result in hospitalization, or the development of drug dependency or drug 
abuse. 
Nonserious AEs are all AEs that do not meet the criteria for a “serious” AE. 
 


Protocol 331-102-00059 
Confidential - Proprietary Information 
77 
Protocol Version 3.0, 23 Jan 2020 
Immediately Reportable Event (IRE): 
• Any SAE 
• Any AE related to occupational exposure. 
• Potential drug-induced liver injury (DILI) (see Section 5.4). 
• Pregnancies are also defined as IREs. Although normal pregnancy is not an AE, it 
will mandate IMP discontinuation and must be reported on an IRE form to the 
sponsor. Pregnancy will only be recorded in the source documents and the AE 
Section of the CRF if there is an abnormality or complication. This applies both to 
pregnancies of subjects and pregnancies of subjects' partners. 
 
Clinical Laboratory Assessment Value Changes: It is the investigator’s or 
subinvestigator’s responsibility to review the results of all laboratory tests as they become 
available. This review will be documented by the investigator’s or subinvestigator’s dated 
signature on the laboratory report. For each abnormal laboratory test result, the 
investigator or subinvestigator needs to verify whether this is an abnormal (ie, clinically 
relevant) change from baseline for that individual subject. This determination, however, 
does not necessarily need to be made the first time an abnormal value is observed. The 
investigator or subinvestigator may repeat the laboratory test or request additional tests to 
verify the results of the original laboratory tests. If this laboratory value is considered 
medically relevant by the investigator or subinvestigator (subject is symptomatic, 
requiring corrective treatment or further evaluation), or if the laboratory value leads to 
discontinuation or meets the criteria for an SAE, this is considered an AE. 
 
Severity: Adverse events will be graded on a 3-point scale and reported. The intensity of 
an AE is defined as follows: 
1 = Mild: Discomfort noticed, but no disruption to daily activity. 
2 = Moderate: Discomfort sufficient to reduce or affect normal daily activity. 
3 = Severe: Inability to work or perform normal daily activity. 
 
IMP Causality: Assessment of causal relationship between an AE and the IMP: 
Related:  
There is a reasonable possibility of a temporal and causal relationship 
between the IMP and the AE. 
Not related: There is no temporal or reasonable relationship between the IMP and the 
AE.

Protocol Version 3.0, 23 Jan 2020 
5.2 
Eliciting and Reporting Adverse Events 
The investigator or subinvestigator will periodically assess subjects for the occurrence of 
AEs. To avoid bias in eliciting AEs, subjects should be asked the nonleading question: 
“How have you felt since your last visit?” For all AEs (serious and nonserious) reported 
by the subject, the event name, start and stop dates, severity, seriousness, relationship to 
IMP, actions taken regarding IMP administration, and outcome thereof must be recorded 
in the source documents and CRFs provided by the sponsor. Adverse event and SAE 
collection is to begin after a subject has signed the ICF. 
Use medical terminology in AE reporting. Adverse events should be reported as a single 
unifying diagnosis whenever possible or, in the absence of a unifying diagnosis, as 
individual signs or symptoms. Exacerbation or disease progression should be reported as 
an AE only if there are unusual or severe clinical features that were not present, or 
experienced earlier, or not expected based on the course of the condition. If a reported 
AE has worsened in severity or seriousness, it should be reported as a new AE on the 
CRF. 
In addition, the sponsor must be notified immediately by e-mail, in principle, of any IREs 
according to the procedure outlined below, in Section 5.3 Immediately Reportable Events. 
Special attention should be paid to recording hospitalization and concomitant medications. 
5.3 
Immediately Reportable Events 
The investigator or subinvestigator must report any SAE, potential DILI, or confirmed 
pregnancy to the sponsor by e-mail (using the contact information on the title page of this 
protocol) immediately after either the investigator, subinvestigator, or designee becomes 
aware of the event. The IRE form and so on should be completed and sent by e-mail, in 
principle, to the sponsor. Please note that the IRE form is NOT the AE Section of the 
CRF. Due consideration must be given to privacy when the IRE form and so on is sent by 
mail or other means of communication. 
For subjects experiencing SAEs or IREs, such AEs should be followed until the events 
are resolved or stabilized, or the subject is lost to follow-up or has died. Resolved means 
that the subject has returned to the baseline state of health, and stabilized means that the 
investigator or subinvestigator does not expect any further improvement or worsening of 
the subject’s condition. It is expected that the investigator or subinvestigator will provide 
or arrange appropriate supportive care for the subject and will provide prompt updates on 
the subject’s status to the sponsor.

5.4 
Potential Drug-induced Liver Injury 
For a subject who experiences an elevation in aspartate aminotransferase (AST) or 
alanine aminotransferase (ALT) that is ≥ 3 times the upper limit of normal (ULN), total 
bilirubin level should also be evaluated. If the total bilirubin is ≥ 2 times the ULN, 
complete the IRE form and so on with all values listed and also report as an AE in the 
source documents and CRF. 
5.5 
Pregnancy 
Women of childbearing potential (WOCBP) are defined as female subjects for whom 
menstruation has started and who are not documented as sterile (ie, have had a bilateral 
oophorectomy and/or hysterectomy or who have been postmenopausal for at least 
12 months). 
For WOCBP and for men who are sexually active, there must be a documented 
agreement that the subject and/or their partner will take effective measures 
(ie, double-barrier method) to prevent pregnancy during the course of the trial and for 
30 days after the last dose of IMP. Unless the subject or their partner is sterile (ie, women 
who have had a bilateral oophorectomy and/or hysterectomy or who have been 
postmenopausal for at least 12 consecutive months; or men who have had a bilateral 
orchidectomy) or remains abstinent, 2 of the following precautions must be used: 
vasectomy, tubal ligation, vaginal diaphragm, intrauterine device, oral contraceptives, or 
condom with spermicide. Any single method of birth control, including vasectomy and 
tubal ligation, may fail, leading to pregnancy. The contraceptive method will be 
documented at each trial visit. 
Before enrolling WOCBP in this clinical trial, investigators or subinvestigators must 
review the below guidelines about trial participation with all WOCBP. The topics should 
generally include: 
• General information 
• Informed consent form 
• Pregnancy prevention information 
• Drug interactions with hormonal contraceptives 
• Contraceptives in current use 
• Guidelines for the follow-up of a reported pregnancy 
 
Before trial enrollment, WOCBP must be advised of the importance of avoiding 
pregnancy during trial participation and the potential risk factors for an unintentional 


Protocol 331-102-00059

80 
Protocol Version 3.0, 23 Jan 2020 
pregnancy. The subject must sign an informed consent form stating that the above-
mentioned risk factors and the consequences were discussed with her. 
During the trial, all WOCBP should be instructed to contact the investigator or 
subinvestigator immediately if they suspect they might be pregnant (eg, missed or late 
menstrual cycle). 
If a subject is suspected to be pregnant before she receives IMP, the IMP administration 
must be withheld until the results of pregnancy tests are available. If the pregnancy is 
confirmed, the subject must not receive the IMP and must not be enrolled in the trial. If 
pregnancy is suspected while the subject is taking IMP, the IMP must be withheld 
immediately (if reasonable, taking into consideration any potential withdrawal risks) until 
the result of the serum pregnancy test is known. If pregnancy is confirmed, the IMP will 
be permanently discontinued in an appropriate manner (eg, dose tapering if necessary for 
subject safety) and the subject will be withdrawn from the trial. 
The investigator or subinvestigator must immediately notify the sponsor of any 
pregnancy associated with IMP exposure during the trial and for 30 days after the last 
dose of IMP, and record the event on the IRE form, and forward it to the sponsor. The 
sponsor will forward Pregnancy Surveillance Form(s) for monitoring the outcome of the 
pregnancy. 
Protocol-required procedures for trial discontinuation and follow-up must be performed 
on the subject unless contraindicated by pregnancy (eg, x-ray studies). Other appropriate 
pregnancy follow-up procedures should be considered, if indicated. In addition, the 
investigator or subinvestigator must report to the sponsor, on appropriate Pregnancy 
Surveillance Form(s), follow-up information regarding the course of the pregnancy, 
including perinatal and neonatal outcome. Infants will be followed for a minimum of 6 
months from the date of birth.

Follow-up of Adverse Events 
5.7.1 
Follow-up of Nonserious Adverse Events 
Nonserious AEs that are identified at any time during the trial must be recorded in the 
source documents and the AE section of the CRF, with the current status (ongoing or 
resolved/recovered) noted. All nonserious events (other than immediately reportable 
events) that are ongoing at the end of trial date (final day of observation) will be recorded 
as ongoing in the source documents and CRF. For any AE having been identified 


Protocol 331-102-00059 
Confidential - Proprietary Information 
81 
Protocol Version 3.0, 23 Jan 2020 
throughout the trial, during data analysis, additional relevant medical history information 
may be requested by the sponsor to further ascertain causality (including, but not limited 
to, information such as risk-related behavior, family history and occupation). The follow-
up information after the end of trial date (final day of observation) will be recorded in the 
subject’s medical record. 
5.7.2 
Follow-up of Serious Adverse Events and Immediately 
Reportable Events 
This trial requires that subjects be actively monitored for SAEs and IREs up to 30 days 
(±5 days) after the final day of IMP administration (end of trial date [final day of 
observation]). 
Serious AEs and IREs that are identified or ongoing at the end of trial date must be 
recorded in the source documents and the AE section of the CRF. Between the end of 
trial date for the individual subject and the end of trial date for the last subject, if any new 
information regarding an SAE or IRE becomes available (eg, the event is resolved), this 
must be reported to the sponsor using the IRE form and so on, and the information must 
be recorded in the source documents and the AE section of the CRF. The investigator or 
subinvestigator will follow SAEs and IREs, and will continue to report any significant 
information to the sponsor until the events are resolved or stabilized, or the subject is lost 
to follow-up or has died, using the IRE form and so on. 
5.7.3 
Follow-up and Reporting of Serious Adverse Events and 
Immediately Reportable Events Occurring After the End of Trial 
Date (Final Day of Observation) 
Any new SAEs or IREs reported to the investigator or subinvestigator, which occur after 
the end of trial date (final day of observation) and are determined by the investigator or 
subinvestigator to be associated with the use of the IMP, should be reported to the 
sponsor. This includes SAEs and IREs that are captured on follow-up telephone contact 
or at any other time point after the defined trial period. The investigator or 
subinvestigator will follow SAEs and IREs identified after the defined trial period and 
continue to report any significant follow-up information to the sponsor until the events 
are resolved or stabilized, or the subject is lost to follow-up or has died, using the IRE 
form and so on.

Statistical Analysis 
This section defines datasets for analysis and describes the methods for analyzing 
endpoints. A detailed statistical analysis plan is provided in a separate Statistical Analysis 
Plan. The Statistical Analysis Plan will be finalized prior to data lock. 
7.1 
Sample Size 
To verify the safety of long-term administration, the target number of subjects to 
complete 52 weeks of administration was set at around 100 subjects. Due to the 
availability of data on safety in elderly subjects from foreign clinical trials, the sample 
size needed to assess the safety of brexpiprazole in the elderly was set as 30 new subjects 
(elderly subjects of age 65 and above) receiving IMP administration. 
7.2 
Datasets for Analysis 
7.2.1 
Efficacy Analysis Set 
The efficacy analysis set will comprise subjects who have received at least 1 dose of the 
IMP, and from whom MADRS total scores have been obtained at baseline and at least 1 
time point after initiation of the treatment. 
7.2.2 
Safety Analysis Set 
The safety analysis set will comprise subjects who have received at least 1 dose of the 
IMP. 
Unless otherwise specified, analysis will be performed for each of the following groups: 
• Rollover subjects from the double-blind trial (331-102-00058) who were assigned to 
the brexpiprazole groups in the double-blind period (Phase B) 
• Rollover subjects from the double-blind trial (331-102-00058) who were assigned to 
the placebo group in the double-blind period (Phase B) 
• All rollover subjects from the double-blind trial (331-102-00058) 
• New subjects (elderly subjects aged 65 years or older) 
• All subjects (rollover and new subjects combined) 
 
7.3 
Handling of Missing Data

Records Management 
9.1 
Source Documents 
Source documents are defined as the results of original observations and activities of a 
clinical investigation. Source documents will include, but are not limited to, medical 
records, electronic data, screening logs, and recorded data from automated instruments. 
All source documents pertaining to this trial will be maintained by the trial site and made 
available for direct inspection by authorized persons. Investigator(s)/ trial site(s) will 
permit trial-related monitoring, audits, IRB review, and regulatory inspection(s) by 
providing direct access to source data/documents by authorized persons as defined in the 
ICF. In all cases, subject confidentiality must be maintained in accordance with 
regulatory requirements. 
9.2 
Data Collection 
During each subject’s visit to the trial site, an investigator or subinvestigator will 
document all significant observations and findings in the medical records. At a minimum, 
these records will contain: 
• Documentation of the informed consent process, including any revised consents; 
• Documentation of the investigator’s or subinvestigator’s decision to enroll the subject 
into the trial, the review of all inclusion/exclusion criteria prior to IMP administration, 
and confirmation of the subject’s actual participation in the trial; 
• The date of the visit and the corresponding Visit or Day in the trial schedule; 
• General subject status remarks, including any significant medical findings. The 
severity, frequency, duration, action taken, and outcome of any AEs and the 
investigator's or subinvestigator’s assessment of relationship to IMP must also be 
recorded; 
• Any changes in concomitant medications or dosages; 
• A general reference to the procedures completed; 
• The signature (or initials) and date of each clinician (or designee) who made an entry 
in the progress notes. 
In addition, any contact with the subject via telephone or other means that provides 
significant clinical information will also be documented in the medical records as 
described above. Any changes to information in the medical records and other source 
documents will be initialed and dated on the day the change is made by a trial site staff 
member authorized to make the change. Changes will be made by striking a single line 
through erroneous data (so as not to obliterate the original data), and clearly entering the 
correct data (eg, wrong data right data). If the reason for the change is not apparent, a 
brief explanation for the change will be written in the source documentation by the 


Protocol 331-102-00059 
Confidential - Proprietary Information 
89 
Protocol Version 3.0, 23 Jan 2020 
investigator or subinvestigator. If electronic data systems are being utilized, a full audit 
trail of changes must be maintained. 
Information from the medical records and other source documents will be entered by trial 
site personnel directly onto electronic CRFs in the sponsor’s electronic data capture 
(EDC) system. Changes to the data will be captured by an automatic audit trail. 
9.3 
File Management at the Trial Site 
The head of the trial site will ensure that the trial site file is maintained in accordance 
with Section 8 of the ICH GCP Guideline E6 and as required by applicable local 
regulations. The trial site will take measures to prevent accidental or premature 
destruction of these documents. 
9.4 
Record Retention at the Trial Site 
The trial site will retain all the trial-related documents and records for whichever is the 
longer of the three periods indicated below. However, if the sponsor requires a longer 
period of archiving, the head of the trial site will consult with the sponsor on the period 
and procedures of record retention. 
• Until the date 2 years after manufacturing and marketing approval date; however, if 
the head of the trial site receives notification from the sponsor that development has 
been terminated or that results of the trial will not be submitted with the approval 
application, until the date 3 years after receipt of such notification. 
• Until the date 3 years after termination or completion of the trial. 
• Until the date on which it is decided to end DNA storage 
 
The trial site must not dispose of any records relevant to this trial without either 
(1) written permission from the sponsor or (2) providing an opportunity for the sponsor to 
collect such records. The trial site will be responsible to maintain adequate and accurate 
electronic or hard copy source documents of all observations and data generated during 
the trial. Such documentation is subject to inspection by the sponsor and relevant 
regulatory authorities. 
10 
Quality Control and Quality Assurance 
10.1 
Monitoring 
The sponsor has ethical, legal, and scientific obligations to follow this trial in accordance 
with established research principles, ICH E6 GCP: Consolidated Guidance, and 
applicable regulatory requirements and laws. As part of a concerted effort to fulfill these 
obligations (maintain current personal knowledge of the progress of the trial), the 


Protocol 331-102-00059 
Confidential - Proprietary Information 
90 
Protocol Version 3.0, 23 Jan 2020 
sponsor’s monitors will visit the site during the trial, as well as communicate frequently 
via telephone, e-mail, and written communications. In addition, all investigators or 
subinvestigators and trial site clinical personnel will undergo initial and ongoing training 
for this particular trial, and this training will be clearly documented. 
10.2 
Auditing 
The sponsor’s Quality Assurance Unit (or representative) may conduct trial site audits. 
Audits will include, but are not limited to, IMP supply, presence of required documents, 
the informed consent process, and comparison of CRFs with source documents. The 
investigator agrees to participate with audits. 
Regulatory authorities may inspect the trial site during or after the trial. The investigator 
will cooperate with such inspections and will contact the sponsor immediately if such an 
inspection occurs. 
11 
Ethics and Responsibility 
This trial must be conducted in compliance with the protocol, ICH GCP Guideline (E6), 
international ethical principles derived from the Declaration of Helsinki and Council for 
International Organizations of Medical Science (CIOMS) guidelines, and applicable local 
laws and regulations. Each trial site will seek approval/favorable opinion by an IRB 
according to the requirements of each region, and the trial site will provide that 
documentation to the sponsor. The IRB will evaluate the ethical, scientific, and medical 
appropriateness of the trial. Further, in preparing and handling source documents, CRFs, 
and the IRE form and so on, the investigator or subinvestigator and their staff will take 
measures to ensure adequate care in protecting subject privacy. To this end, a subject ID 
will be used to identify each subject. Financial aspects, subject insurance, and publication 
policy for the trial will be documented in the agreement between the sponsor and the trial 
site. 
12 
Confidentiality 
All information generated in this trial will be considered confidential and will not be 
disclosed to anyone not directly concerned with the trial without the sponsor’s prior 
written permission. Subject confidentiality requirements of the region where the trial is 
conducted will be met. However, authorized regulatory officials and sponsor personnel 
(or their representatives) may be allowed full access to inspect and copy the records, 
consistent with local requirements. All IMPs, subject bodily fluids, and other materials 
collected shall be used solely in accordance with this protocol, unless otherwise agreed to 
in writing by the sponsor. 


Protocol 331-102-00059 
Confidential - Proprietary Information 
91 
Protocol Version 3.0, 23 Jan 2020 
Subjects will be identified only by a unique subject ID in the source documents and CRFs. 
If further subject identification is required, subjects’ full names may be made known to a 
regulatory agency or other authorized officials if necessary, subject to local regulations. 
13 
Amendment Policy 
The investigator will not make any changes to this protocol without the sponsor’s prior 
written consent and subsequent approval/favorable opinion by the IRB. Any permanent 
change to the protocol, whether an overall change or a change for specific trial site(s), 
must be handled as a protocol amendment. Any amendment will be written by the 
sponsor. Each amendment will be submitted to the IRB, as required by local regulations. 
Except for “administrative” or “nonsubstantial” amendments, investigators or 
subinvestigators will wait for IRB approval/favorable opinion of the amended protocol 
before implementing the change(s). Administrative amendments are defined as having no 
effect on the safety of subjects, conduct or management of the trial, trial design, or the 
quality or safety of IMP(s) used in the trial. A protocol change intended to eliminate an 
apparent immediate hazard to subjects should be implemented immediately, followed by 
IRB notification within local applicable timelines. The sponsor will submit protocol 
amendments to the applicable regulatory agency within local applicable timelines. 
When the IRB, investigators, or the sponsor concludes that the protocol amendment 
substantially alters the trial design or increases the potential risk to the subject, the 
currently approved written ICF will require similar modification. In such cases, after 
approval/favorable opinion of the new ICF by the IRB, repeat written informed consent 
will be obtained from subjects enrolled in the trial before expecting continued 
participation and before the amendment-specified changes in the trial are implemented. 
14 
Publication Authorship Requirements 
Authorship for any Otsuka-sponsored publications resulting from the conduct of this trial 
will be based on International Committee of Medical Journal Editors (ICMJE) authorship 
criteria (http://www.icmje.org/recommendations). According to ICMJE guidelines, one

Introduction 
This statistical analysis plan documents in detail the statistical analysis methods planned 
for Trial 331-102-00059. 
2 
Trial Objectives 
The objective of the trial is to assess the safety and efficacy of the long-term use of 
brexpiprazole as adjunctive therapy in concomitant use with a commercially available 
antidepressant (selective serotonin reuptake inhibitor [SSRI] or serotonin-noradrenaline 
reuptake inhibitor [SNRI] for rollover subjects and SSRI, SNRI, or mirtazapine for new 
subjects) in subjects with major depressive disorder who continue receiving the treatment 
from the double-blind trial (331-102-00058) and in newly enrolled patients 65 years or 
older with major depressive disorder. 
3 
Trial Design 
3.1 
Type/Design of Trial 
The trial is a multi-center, open-label trial to assess the safety and efficacy of the long-
term use of brexpiprazole as adjunctive therapy in conjunction with a commercially 
available antidepressant (SSRI or SNRI for rollover subjects and SSRI, SNRI, or 
mirtazapine for new subjects) at a dose and regimen specified in the package insert. 
Subjects of the trial are those who have completed the double-blind period (Phase B) of 
the double-blind trial (331-102-00058), and newly enrolled patients 65 years or older 
with major depressive disorder who have received 1 to 3 adequate antidepressant drug 
treatmentsa for major depressive episodes and have shown an inadequate responseb to all 
of these treatments. 
The trial design is shown in Figure 3.1-1. The trial comprises a screening period, 
treatment period, and post-treatment observation period. 
aDefinition of "adequate antidepressant drug treatment" is provided below. 
Treatment with an antidepressant at an approved dose for at least 6 weeks (for combination therapy, 
treatment for at least 3 weeks) 
bDefinition of "inadequate response" is provided below. 
With complete recovery from depressive symptoms and not the slightest improvement considered as 
100% and 0%, respectively, patients carry out self-evaluations for improvement by antidepressant 
drug treatments used to date, from among 4 grades (< 25% Improvement, 25% to 49% Improvement, 
50% to < 75% Improvement, and ≥ 75% Improvement), with the evaluations corresponding to < 25% 
Improvement or 25% to 49% Improvement classified as inadequate response. 
Patients who, among 1 to 3 adequate antidepressant drug treatments, have received treatment for 
≥ 6 weeks at least once (receiving only combination therapies for ≥ 3 weeks does not qualify) are 
eligible for selection.

Trial Design 
aAdministration of brexpiprazole will commence at 1 mg/day and the dose will be increased to 2 mg/day 
after observations, examinations, and assessments at Week 1. Subjects who cannot tolerate doses of 
2 mg/day will be withdrawn from the trial. 
 
3.2 
Trial Treatments 
1) Drugs, dose, and regimen 
• Commercially available antidepressant 
For rollover subjects, an antidepressant (SSRI or SNRI) used in the double-blind 
trial (331-102-00058) will continue to be used throughout the treatment period, 
with no changes from the final dose and regimen. For new subjects, an 
antidepressant (SSRI, SNRI, or mirtazapine) being used at the time of informed 
consent will continue to be used throughout the treatment period, with no changes 
from the dose and regimen used at informed consent. 
During the treatment period, dose adjustment within the approved dose range is 
allowed according to the judgement of the investigator or subinvestigator, but the 
dose may not be altered at the time of dose escalation of brexpiprazole at Week 1.

• Brexpiprazole 
Administration of brexpiprazole will commence at 1 mg/day and subjects will 
continue to receive a single brexpiprazole 1 mg tablet once daily by the oral route 
until the observations, examinations, and evaluations at Week 1. Following the 
observations, examinations, and evaluations at Week 1, subjects will be 
administered a single brexpiprazole 2 mg tablet once daily by the oral route. 
Subjects who cannot tolerate doses of 2 mg/day will be withdrawn from the trial. 
 
2) Treatment period 
52 weeks 
3.3 
Trial Population 
Adult and elderly patients with "major depressive disorder, single episode" or "major 
depressive disorder, recurrent episode" according to the classification criteria of the 
Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) 
3.3.1 
Number of Subjects and Trial Population 
The trial will be conducted in patients who have major depressive disorder (major 
depressive disorder, single episode; major depressive disorder, recurrent episode) 
according to the DSM-5 classification. Concerning rollover subjects from the double-
blind trial (331-102-00058), their eligibility for proceeding to the long-term trial will be 
assessed, after acquisition of informed consent to the long-term trial, based on the results 
of examinations and assessments at Week 6 of the double-blind period (Phase B) of the 
double-blind trial (331-102-00058) and at baseline. The eligibility of new subjects will be 
judged after acquisition of informed consent from elderly patients 65 years or older, 
based on the results of examinations and assessments at screening and baseline. As the 
sample size needed to assess the safety and efficacy of brexpiprazole in the elderly, the 
number of subjects receiving the treatment was set at 30. 
3.4 
Trial Visit Window 
For all endpoints, acceptable windows for analysis are specified, and analysis should be 
based on the analysis time points regardless of time points recorded on the case report 
form. 
Acceptable windows for analysis are shown in Table 3.4-1. Day 1 is defined as the day 
when treatment with the investigational medicinal product (IMP) begins. If multiple data 
exist within an acceptable window, the last data within the window will be used in 
analysis. Data obtained 7 days or later after the final dosing will be excluded from the 
analysis.

The AIMS total score will be the sum of scores for AIMS items 1 through 7. 
4 
Sample Size 
To verify the safety of long-term administration, the target number of subjects to 
complete 52 weeks of administration was set at around 100 subjects. Due to the 
availability of data on safety in elderly subjects from foreign clinical trials, the sample 
size needed to assess the safety of brexpiprazole in the elderly was set as 30 new subjects 
(elderly subjects of age 65 and above) receiving IMP administration. 
5 
Statistical Analysis Datasets 
In this trial, unless otherwise specified, analysis will be performed for each of the 
following groups: 
• Rollover subjects from the double-blind trial (331-102-00058) who were assigned to 
the brexpiprazole groups in the double-blind period (Phase B) 
• Rollover subjects from the double-blind trial (331-102-00058) who were assigned to 
the placebo group in the double-blind period (Phase B) 
• All rollover subjects from the double-blind trial (331-102-00058) 
• New subjects (elderly subjects aged 65 years or older) 
• All subjects (rollover and new subjects combined) 
 
5.1 
Efficacy Analysis Set 
The efficacy analysis set will comprise subjects who have received at least 1 dose of the 
IMP, and from whom MADRS total scores have been obtained at baseline and at least 1 
time point after initiation of the treatment. Subjects who did not comply with Good 
Clinical Practice (GCP) will be excluded. 
5.2 
Safety Analysis Set 
The safety analysis set will comprise subjects who have received at least 1 dose of the 
IMP. Subjects who did not comply with GCP will be excluded. 
5.3 
Handling of Missing Data 
The analysis of last assessment time point will be performed using the last observation 
carried forward method (herein after referred to as "LOCF"), by which missing data at 
Week 52 will be imputed by the last observed data after initiation of IMP treatment.

Subject Disposition 
Numbers and proportions of subjects from whom informed consent was obtained, those 
who received trial treatment, those who completed the trial, those who discontinued the 
trial, those who discontinued the trial by reason, and those included in each analysis set 
will be summarized. Similar summarization will be performed for each requisite 
concomitant medication. 
Numbers and proportions of subjects who completed the trial will be summarized for 
each period (days) (1-7, 8-14, 15-28, 29-56, 57-84, 85-112, 113-140, 141-168, 169-196, 
197-224, 225-252, 253-280, 281-308, 309-336, 337-364, > 364).

hereinafter the same applies) of age, height, body weight, waist circumference, and body 
mass index (BMI) and frequency distribution of sex, race, ethnicity, country where trial is 
conducted, medical history, and complications will be determined in each analysis set. 
Similar summarization will be performed for each requisite concomitant medication. 
In rollover subjects, baseline data in the present trial will be used for body weight, waist 
circumference, and BMI. For medical history and complications, baseline data in the 
present trial as well as in the double-blind trial (331-102-00058) will be used. For the 
other demographic characteristics, baseline data in the double-blind trial (331-102-00058) 
will be used. 
7.3

age at initial onset, duration (months) of major depressive episode from initial onset, 
MADRS total score, HAM-D17 total score, and CGI-S and frequency distribution of 
DSM-5-based diagnosis (single, recurrent), severity (mild, moderate, severe), specific 
terms (“not applicable,” “applicable,” and disposition of each specific term), frequency of 
major depressive episodes (1, 2, 3, 4, ≥ 5), frequency of appropriate antidepressant drug 
treatments of the current major depressive episode (1, 2, 3) will be determined in each 
analysis set. Similar summarization will be performed for each requisite concomitant 
medication.

Version: 2.0 Date: 19/07/2022 
In rollover subjects, baseline data in the present trial will be used for MADRS total score, 
HAM-D17 total score, and CGI-S. For the other demographic characteristics, baseline 
data in the double-blind trial (331-102-00058) will be used. 
The duration of the current major depressive episode and the duration of major 
depressive episode from initial onset will be calculated using the following formula: 
duration (months) = (date of subject demographic evaluation – date of onset + 1) / 30. 
Any unknown month or day of onset will be replaced with June or 15, respectively. 
7.4 
Treatment Compliance 
Treatment compliance (number of days when the subject actually received the 
IMP/number of days for which the IMP was prescribed) will be grouped into < 70%, 
≥ 70% to < 80%, ≥ 80% to < 90%, and ≥ 90%, and its frequency distribution will be 
determined in the efficacy analysis set. 
7.5 
Prior and Concomitant Medications 
Numbers and proportions of subjects who used medications before, during, and after the 
treatment period will be determined by drug class and preferred term of the World Health 
Organization Drug Dictionary (WHODD) version Global B3 March 2018 in the safety 
analysis set. 
Similar summarization will be performed for antipsychotics.

Changes in the Planned Analyses 
• The following changes were made to categorical analyses of QTc: 
Only subjects with postdose QTc meeting the criteria will be summarized, instead of 
summarization at all time points. 
Only subjects with QTc not meeting the criteria at baseline and meeting the criteria 
after baseline will be summarized. 
• C-SSRS will be analyzed in the overall period after initiation of IMP treatment, not at 
the last assessment time point.
