Brief summary:
To compare the efficacy of 2 fixed doses of brexpiprazole with placebo in participants with agitation associated with dementia of the Alzheimer's type.

Detailed description:
Behavioral symptoms, such as agitation, are core features in participants with Alzheimer's disease and related dementias and develop in the majority of dementia participants. The presence of agitation in participants with Alzheimer's disease places a significant burden not only on participants and their caregivers but also on the healthcare system.

This is a trial designed to assess the safety and efficacy of brexpiprazole in the treatment of participants with agitation associated with dementia of the Alzheimer's Type. The trial consists of a continuous 12-week double-blind treatment period with a 30-day follow-up. The trial population will include male and female participants between 55 and 90 years of age (inclusive) with a diagnosis of probable Alzheimer's disease, who are residing either in an institutionalized setting or in a non-institutionalized setting where the participant is not living alone.

Protocol Title:
A Phase 3, 12-week, Multicenter, Randomized, Double-blind, 
Placebo-controlled Trial to Evaluate the Efficacy, Safety, and 
Tolerability of 2 Fixed Doses of Brexpiprazole (OPC-34712) in 
the Treatment of Subjects with Agitation Associated with 
Dementia of the Alzheimer’s Type
Clinical Phase:
3
Treatment Indication: 
Agitation associated with dementia of the Alzheimer’s type
Objective(s):
Primary:  To compare the efficacy of 2 fixed doses (1 mg/day 
and 2 mg/day) of brexpiprazole with placebo in subjects with 
agitation associated with dementia of the Alzheimer’s type, as 
assessed by the Cohen-Mansfield Agitation Inventory (CMAI) 
after 12 weeks of treatment.
Secondary:  To evaluate the safety and tolerability of 2 fixed 
doses of brexpiprazole (1 mg/day and 2 mg/day) compared with 
placebo in subjects with agitation associated with dementia of 
the Alzheimer’s type after 12 weeks of treatment.
Trial Design:
This is a phase 3, 12-week, multicenter, randomized, 
double-blind, placebo-controlled, 3-arm, fixed-dose trial 
designed to assess the efficacy, safety, and tolerability of 
brexpiprazole (1 mg/day and 2 mg/day) in the treatment of 
subjects with agitation associated with dementia of the 
Alzheimer’s type.  The trial population will include male and 
female subjects between 55 and 90 years of age (inclusive), 
who are living in either an institutionalized setting or in a 
non-institutionalized setting where the subject is not living 
alone. In both the institutionalized and non-institutionalized 
settings, the subject must have a caregiver who can spend a 
minimum of 2 hours per day for 4 days per week with the 
subject in order to assess changes in the subject’s condition.
All subjects must have a diagnosis of probable Alzheimer’s 
disease according to the National Institute of Neurological and 
Communicative Disorders and Stroke and the Alzheimer’s 
Disease and Related Disorders Association 
(NINCDS-ADRDA) criteria.
The trial comprises a 2- to 42-day screening period, a 12-week 
double-blind treatment period, and a 30-day post-treatment

follow-up period.  
 
 
  
This trial will be monitored under the supervision of an 
independent Data Monitoring Committee (DMC).  The DMC 
will monitor safety periodically, based on a predetermined 
schedule.  The details of the DMC structure and its roles and 
responsibilities will be documented in a DMC charter.
The trial is organized as follows:
Screening Period:
The screening period will range from 2 days to 42 days and will 
begin when the informed consent form (ICF) is signed, prior to 
the initiation of any procedures.  The screening period may be 
extended after discussion with and approval by the medical 
monitor.
The investigator must assess the capacity of the subject to 
provide informed consent during the screening period and 
throughout the course of the trial. Determinations by the 
investigator of the capacity of the subject to provide informed
consent and the options for obtaining informed consent from 
and/or on behalf of the subject under each potential 
circumstance will be made and implemented according to strict 
criteria.
 
An interactive voice response system (IVRS) or interactive web 
response system (IWRS) will be used to obtain the subject trial
identification number for each subject with a signed ICF.
The purpose of the screening period is to determine the 
subject’s eligibility and to washout prohibited concomitant 
pharmacotherapy prior to randomization.  The subject should 
be randomized into the double-blind treatment period as soon 
as all the screening assessments are completed, the screening 
and baseline eligibility criteria have been met, and the required 
washout period has occurred.

The dose will then be increased to 1 mg/day starting on the 
day after the Week 2 visit (ie, Day 15 [±2 days]).  

Subjects will remain on this dose until Week 12/Early 
Termination (ET) (the last day of the Treatment Period).
For subjects randomly assigned to the brexpiprazole 2 mg/day 
treatment group:

The dose of IMP will be increased from 0.25 mg/day to 
0.5 mg/day starting on the day after the Day 3 visit (ie, 
Day 4 [+2 days]).  

The dose will then be increased to 1 mg/day starting on the


The dose will then be increased to 2 mg/day starting on the 
day after the Week 4 visit (Day 29 [±2 days]).  

Subjects will remain on this dose until Week 12/ET (the last 
day of the Treatment Period).
For subjects randomly assigned to receive placebo, their dose 
of IMP will be administered daily starting on the day after the 
Baseline visit (ie, Day 1) and ending on Week 12/ET (the last 
day of the Treatment Period).
Subjects unable to tolerate their assigned dose of brexpiprazole 
(or matching placebo) will be discontinued from the trial.  
Down-titration is not allowed at any time during the trial.  
If a subject is discontinued from the trial, every effort will be 
made to complete all of the Week 12/ET evaluations prior to 
administering any additional medications for the treatment of 
agitation or other prohibited medications.
Subjects will be evaluated at Baseline, Day 3, and at Weeks 2, 
4, 6, 8, 10, and 12 during the double-blind treatment period.  
All trial visits will take place as a clinic visit at either the 
investigator’s site or residential facility, if applicable.  All 
attempts should be made to maintain the subjects’ normal 
routine with regard to physician appointments.  Individual 
circumstances that fall outside this general convention should 
be discussed with the medical monitor in order to determine 
appropriateness to proceed.  In addition, the subject’s 
identified caregiver will be contacted by telephone at Weeks 3, 
5, and 7 to assess compliance with IMP, confirm any changes 
to concomitant medications, and assure the subject’s 
well-being.  Trial-related efficacy and safety assessments will 
be performed as outlined in the Schedule of Assessments.

Follow-up Period:
All subjects, whether they complete the trial or are withdrawn 
prematurely for any reason, will be followed up for a safety 
evaluation 30 (+ 2) days after the last dose of IMP during a 
clinic visit at either the investigator’s site or residential facility, 
if applicable.  If a clinic visit is not possible, the subject should 
be assessed by telephone contact with the subject and a 
caregiver. 
 
Subjects who complete both the 12-week double-blind 
treatment period and the 30-day safety follow-up visit are 
eligible to enroll into Trial 331-13-211, which is a 2-month, 
observational, rollover trial to evaluate the safety of subjects 
with agitation associated with Alzheimer's disease who 
previously participated in Trial 331-12-283. For those subjects 
who plan to enroll into Trial 331-13-211, the 30-day safety 
follow-up visit for Trial 331-12-283 will occur as a clinic visit 
at either the investigator’s site or residential facility, if 
applicable. 
Subject Population:
The subject population will include male and female subjects 
between 55 and 90 years of age (inclusive), who are living in 
either an institutionalized setting or in a non-institutionalized 
setting where the subject is not living alone. In both the 
institutionalized and non-institutionalized settings, the subject 
must have a caregiver who can spend a minimum of 2 hours per 
day for 4 days per week with the subject in order to assess 
changes in the subject’s condition. All subjects must have a 
diagnosis of probable Alzheimer’s disease according to the 
NINCDS-ADRDA criteria.  Subjects must have a previous 
magnetic resonance imaging (MRI) or computed tomography 
(CT) scan of the brain, which was performed after the onset of 
symptoms of dementia, with findings consistent with a 
diagnosis of Alzheimer’s disease.  If a previous MRI or CT 
scan of the brain performed after the onset of the symptoms of 
dementia is not available, then an MRI/CT scan should be 
performed during screening.  Additionally, at both the 
screening and baseline visits, subjects must have a Mini-Mental 
State Examination (MMSE) score of 5 to 22, inclusive, and a 
total score (frequency × severity) of ≥4 on the 
agitation/aggression item of the Neuropsychiatric Inventory—
Nursing Home (NPI-NH) or the Neuropsychiatric Assessment 
for Non-institutionalized Patients based on the NPI/NPI-NH

(hereafter referred to as “NPI/NPI-NH”). The NPI-NH will be 
used for institutionalized subjects and the NPI/NPI-NH will be 
used for non-institutionalized subjects.  The onset of the 
subject’s symptoms of agitation must be at least 2 weeks prior 
to the screening visit. Subjects must require pharmacotherapy 
for the treatment of agitation per the investigator’s judgment, 
after an evaluation for reversible factors (eg, pain, infection, 
polypharmacy) and a trial of nonpharmacological interventions.
Subjects must have been residing at their current location for at 
least 14 days before screening and be expected to remain at the 
same location for the duration of the trial.  Subjects who at any 
point during the double-blind treatment phase transfer from an 
institutionalized setting to a non-institutionalized setting, or 
vice versa, will be withdrawn from the trial.  In case of a brief 
hospitalization, determination of subject eligibility to stay in the 
trial must be made based on subject safety by the investigator 
and medical monitor.  All attempts should be made to 
maintain the subjects’ normal routine with regard to 
appointments with physicians and overnight 
accommodations.  Subjects in an institutionalized setting may 
receive supervised day passes at the discretion of the 
investigator and may also receive supervised overnight passes 
at the discretion of the investigator as long as such overnight 
stays are part of the subjects’ normal routine.
Subjects in a non-institutionalized setting may have a caretaker 
as well as a caregiver. The subject’s caretaker is the person 
who lives with and cares for the subject on a regular basis.  The 
caretaker may be supported in providing care to the subject by a 
professional(s), friend(s), or family member(s).  For purposes 
of this trial, the subject’s caregiver is the person who has 
sufficient contact to describe the subject’s symptoms and who 
has direct observation of the subject’s behavior in order to 
participate in the interview for the CMAI, NPI/NPI-NH, and 
other applicable trial assessments.  
For subjects in an institutionalized setting, there is only one role 
defined and that is the role of caregiver.  The identified 
caregiver can be a staff member of the institutionalized setting 
or another individual (eg, family member, family friend, hired 
professional caregiver) who has sufficient contact to describe 
the subject’s symptoms and who has direct observation of the 
subject’s behavior in order to participate in the interview for the 
CMAI, NPI-NH, and other applicable trial assessments.

investigator’s judgment.
Trial Sites:
It is planned that approximately 840 subjects will be screened 
at approximately 85 trial sites worldwide so that approximately 
420 subjects will be randomized to treatment.
Investigational 
Medicinal Product, 
Dose, Formulation, 
Mode of 
Administration:
The IMP will consist of brexpiprazole tablets (identical 
0.25-mg, 0.5-mg, 1-mg, and 2-mg tablets) and matching 
placebo tablets.  The 0.25 mg/day dose will be supplied as a 
blister card containing sufficient tablets for 3 (+2) days; the 
0.5 mg/day, 1 mg/day, and 2 mg/day doses will be supplied as a 
weekly blister card containing sufficient tablets for 
7 (+ 2) days.  An IVRS or IWRS will be used at each trial site 
to assign the specific blister-card number to be dispensed to 
each subject at each visit.
After a 2- to 42-day screening period, eligible subjects will be 
randomly assigned to 1 of 3 treatment groups (2 active 
brexpiprazole groups [1 mg/day or 2 mg/day] or placebo).  
The total duration of double-blind treatment will be 12 weeks 
for all randomized subjects.
All doses of brexpiprazole and matching placebo will be taken 
orally once daily, preferably in the morning, and can be 
administered without regard to meals.  Brexpiprazole should be 
taken at approximately the same time each day, particularly 
prior to visits with pharmacokinetic sampling.
Criteria for 
Evaluation:
Primary Efficacy Variable:
The primary efficacy variable is the change from baseline to 
Week 12/ET in the CMAI total score.
Key Secondary Efficacy Variable:
The key secondary efficacy variable is the change from 
baseline to Week 12/ET in the Clinical Global 
Impression-Severity of Illness (CGI-S) score, as related to 
agitation.

Pharmacokinetic samples for determination of brexpiprazole 
and its metabolite(s) will be collected at the baseline visit and at 
the Week 8 and Week 12/ET trial visits, at the same time as the 
sample collection for the clinical laboratory tests. 
 
 
 
 
 
Statistical Methods:
Descriptive statistics will be provided for all efficacy and safety 
variables in general.  Continuous variables will be summarized 
by tabulations of mean, median, range, and standard deviation 
(SD).  Tabulations of frequency distributions will be provided 
for categorical variables.  The primary endpoint will be
analyzed using a mixed-effect model repeated measure 
(MMRM) methodology.  The model will include fixed 
class-effect terms for treatment, trial center, visit week, and an 
interaction term of treatment by visit week and include the 
interaction term of baseline values of CMAI total score by visit 
week as a covariate.  The primary efficacy outcome measure is 
the mean change from baseline (Day 0 visit) to the end of the 
double-blind treatment period (Week 12 visit) in the CMAI 
total score. 
 
 
 
The primary statistical comparisons of interest are 
brexpiprazole 2 mg/day versus placebo and brexpiprazole 
1 mg/day versus placebo.  To protect the experiment-wise alpha 
level at 0.05 when making 2 comparisons of brexpiprazole 
doses versus placebo, the statistical testing will be carried out 
using a hierarchical testing procedure in the order of 1) 
comparison of 2 mg/day brexpiprazole versus placebo and 2) 
comparison of 1 mg/day brexpiprazole versus placebo.  Thus, if 
the test yields a statistically significant result at 0.05 (2-sided) 
for the comparison of 2 mg/day brexpiprazole versus placebo, 
then the comparison of 1 mg/day brexpiprazole versus placebo 
will be tested at an alpha level of 0.05 (2-sided).

If the primary efficacy analysis for the CMAI total score yields 
a statistically significant result at 0.05 (2-sided) for both of the 
comparisons of brexpiprazole 1 mg/day and 2 mg/day versus 
placebo, then the corresponding comparison for the key 
secondary efficacy variable (CGI-S score) will be tested at an 
alpha level of 0.05 (2-sided) using another hierarchical testing 
procedure in the order of brexpiprazole 2 mg/day versus 
placebo and brexpiprazole 1 mg/day versus placebo.  Thus, 
brexpiprazole 1 mg/day versus placebo will be tested only if 
brexpiprazole 2 mg/day versus placebo reaches significance at 
0.05 (2-sided) for this key secondary efficacy variable.
The sample size was calculated based on the treatment effect of 
6.5 points with an SD of 16.5 in the change from baseline 
(Day 0 visit) to the end of the double-blind treatment period 
(Week 12 visit) in the CMAI total score, to achieve 85% power 
at a 2-sided alpha level of 0.05.  This results in 117 subjects in 
each of the groups (ie, brexpiprazole 1 mg/day, brexpiprazole 
2 mg/day, and placebo).  After allowance of 10% non-evaluable 
subjects, the total number of subjects to be randomized is 
132 per treatment arm.  
 
 
 
 
 
he total number of subjects to be randomized will 
be approximately 420 
 
  The 
sample size was estimated based on a 1:1:1 randomization ratio 
(brexpiprazole 1 mg/day, brexpiprazole 2 mg/day, placebo, 
respectively).  The randomization will be stratified by center.

1. Introduction
Dementia is a term that describes disorders that cause cognitive decline. The most 
common type of dementia is Alzheimer’s disease.1  It is currently estimated that 
5.3 million Americans have Alzheimer’s disease, and future projections estimate that, due 
to an increase in the aging population, there will be between 11 million and 16 million 
Americans with Alzheimer’s disease by 2050.1  In the United States, among adults over 
age 65, prevalence estimates of dementia range from 5% to 15%, with Alzheimer’s 
disease being the most common type of dementia.2,3,4  Dementia is the most frequent 
contributing factor to the transition from home-based care to long-term-care facility, such 
as a nursing home, assisted living facility, or group home.  Across numerous studies, it 
has been consistently demonstrated that cognitive decline, behavioral disturbances, and 
depression associated with Alzheimer’s disease are strong predictors of nursing home 
admission.5
Neuropsychiatric symptoms, including agitation and aggression, are core features of 
Alzheimer’s disease and related dementias.  Alzheimer’s disease-associated behavioral 
disturbances lead to frequent emergency room visits and can lead to mismanagement of 
other medical conditions.  These behavioral disturbances are also associated with major 
adverse effects on quality of life (QoL) and reduced time to institutionalization.  
Neuropsychiatric symptoms also have a major adverse effect on caregivers.5  These 
neuropsychiatric symptoms contribute to subject and caregiver distress6 and increased 
healthcare costs7 and may even lead to institutionalization.8
Currently, there is no cure for Alzheimer’s disease and no treatment approved in the 
United States for the management of behavioral disturbances, including agitation, in 
patients with Alzheimer’s disease.  In some countries of the European Union (EU), 
risperidone is indicated for the short-term treatment (up to 6 weeks) of persistent 
aggression in subjects with moderate to severe Alzheimer's dementia unresponsive to 
nonpharmacological approaches and when there is a risk of harm to self or others.9  
Adequate treatment of behavioral disturbances is essential to increasing the comfort and 
safety of subjects and easing the burden of provision of care by families and other 
caregivers and remains an ongoing and serious unmet medical need in this subject
population.
In the literature, agitation has been defined as “inappropriate verbal, vocal, or motor 
activity that is not judged by an outside observer to result directly from the needs or

confusion of the agitated individual.”  Agitation is a term used by clinicians for a group 
of symptoms that may reflect an underlying disorder.10,11  Agitated behavior is 
considered to be socially inappropriate and may be:

Abusive or aggressive toward self or others, such as hitting or kicking

An appropriate behavior that is performed with an inappropriate frequency, such as 
constantly asking questions11

Considered inappropriate according to social standards, such as putting on too many 
layers of clothes
Brexpiprazole (also referred to as OPC-34712 or Lu AF41156) is an organic compound 
synthesized by Otsuka Pharmaceutical Co, Ltd, that is a partial agonist at dopamine 
type 2 (D2), dopamine type 3 (D3), and serotonin type 1A (5-HT1A) receptors and an 
antagonist at serotonin type 2A (5-HT2A) receptors; and has a low binding affinity for 
histamine and muscarinic receptors.  Details of the receptor affinity profile of 
brexpiprazole are summarized in Section 1.1.1.  Activity at dopamine and serotonin 
receptors has been shown to be useful in the treatment of psychiatric disorders, eg, 
schizophrenia and bipolar mania.  Hence, brexpiprazole is expected to be a promising 
antipsychotic agent.  As the relative activity at these and other receptors appears to be 
related to the side effect profiles of antipsychotic drugs,12,13,14,15 brexpiprazole may have 
the potential to exhibit improved safety compared with other agents.  The more potent 
antagonism at 5-HT2A receptors for brexpiprazole relative to aripiprazole, another D2 
partial agonist, may afford a more favorable profile with respect to sleep quality; whereas 
the low binding affinities for histamine and muscarinic receptors suggest that 
brexpiprazole may have less potential to cause H1-receptor-related weight gain than 
olanzapine.  Preclinical data also suggest that brexpiprazole will have lower potential for 
hyperprolactinemia than risperidone.  Results from initial phase 2 trials showed 
brexpiprazole to be well tolerated by subjects with major depressive disorder (MDD), 
attention-deficit/hyperactivity disorder (ADHD), and schizophrenia (see Section 1.2 and 
Section 1.3).

Nonclinical Data
Efficacy and safety pharmacology are summarized in Section 1.1.1 and Section 1.1.2, 
respectively.  A complete description of the available data from nonclinical studies, 
including pharmacokinetic and toxicology studies in different animal species, can be 
found in the Investigator’s Brochure.16
1.1.1.
Efficacy Pharmacology
Brexpiprazole functions as a partial agonist at the D2 receptor.  In in vitro assay systems, 
based on forskolin-induced cyclic adenosine monophosphate (AMP) accumulation and 
calcium (Ca2+) mobilization in human dopamine D2L receptor-expressing cells, its 
intrinsic activity at the D2 receptor was slightly lower than that of aripiprazole.  
Brexpiprazole inhibited apomorphine (APO)-induced hyperlocomotion, APO-induced 
stereotyped behavior, and conditioned avoidance response in rats, which are predictive 
animal models for antipsychotic-like efficacy.  The inhibitory effects of brexpiprazole 
were more potent than those of aripiprazole.  Moreover, in contrast to the D2 receptor 
antagonist risperidone, brexpiprazole did not increase plasma prolactin levels in 
reserpine-treated rats, thus demonstrating a D2 receptor partial agonistic profile in vivo.  
Despite its lower intrinsic activity at the D2 receptor, the in vivo catalepsy liability of 
brexpiprazole, an index of extrapyramidal symptoms (EPS), was similar to that of 
aripiprazole, but still lower than that of the typical antipsychotic haloperidol.  
Furthermore, brexpiprazole showed high binding affinity for the 5-HT2A receptor and 
dose-dependently inhibited ()-2,5-dimethoxy-4-iodoamphetamine-induced head twitch 
response in rats, indicating that the compound has 5-HT2A receptor antagonistic activity; 
and the effect of brexpiprazole was more potent than that of aripiprazole.  In addition, 
brexpiprazole acted as a partial agonist, exhibiting high binding affinities for the D3 and 
5-HT1A receptors.
1.1.2.
Safety Pharmacology
In safety pharmacology studies in rats at an oral dose of 30 mg/kg or higher, 
brexpiprazole induced pharmacologically-mediated clinical signs considered to be due to 
depression of the central nervous system (CNS) and dose-dependent decreases in body 
temperature.  When orally administered at up to 30 mg/kg in conscious male beagle dogs, 
brexpiprazole showed no effect on respiratory parameters or heart rate at any dose tested.  
Brexpiprazole decreased blood pressure at doses of 3 mg/kg or higher and prolonged both 
the QT interval and the corrected QT interval (QTc) by Van de Water’s formula at

30 mg/kg.  Brexpiprazole inhibited human ether-a-go-go related gene (hERG) current in 
Chinese hamster ovary cells (CHO-K1) at concentrations of 10−8 mol/L or higher, with a 
50% inhibitory concentration of 1.17 10−7 mol/L.  The mechanism for the blood 
pressure decreasing effect of brexpiprazole was suggested to result from a blockade of 
the 1-adrenoceptor in peripheral blood vessels, which is a part of the compound’s 
pharmacological profile.  Proarrhythmic risk was also evaluated by examining the effects 
of brexpiprazole on monophasic action potential parameters in halothane-anesthetized 
dogs.  Brexpiprazole did not affect the terminal repolarization period even at an 
intravenous dose of 3 mg/kg, suggesting a low potential for proarrhythmic effects.  In 
general, the changes in the CNS, respiratory, and cardiovascular systems observed with 
brexpiprazole occurred at doses or exposure levels higher than those at which efficacy 
was confirmed in rats (3 mg/kg), and similar changes were shown to occur after 
administration of risperidone at similar or lower doses.
1.2.
Clinical Data
1.2.1.
Pharmacokinetics and Pharmacodynamics
The pharmacokinetics of single and multiple doses of brexpiprazole were studied in 
healthy subjects and in subjects with MDD, ADHD, and schizophrenia or schizoaffective 
disorder.  Based on preclinical data and human clinical trials, brexpiprazole and the 
metabolite DM-3411 were identified as the major analytes that are present in human 
plasma.  In vitro, the activity of DM-3411 is 17 times lower than that of brexpiprazole; 
thus, it is considered an inactive metabolite.  Both brexpiprazole and its major metabolite, 
DM-3411, pharmacokinetics were linear following administration of single doses (0.2 to 
8 mg) and multiple daily doses (0.5 to 2 mg in healthy subjects and 1 to 12 mg in 
schizophrenic subjects).  At steady state, the brexpiprazole and DM-3411 mean terminal 
elimination half-life was 95.4 and 89.3 hours, respectively.  The median time to 
maximum (peak) plasma concentration (tmax) occurred at approximately 2 to 6 hours 
postdose for brexpiprazole and at approximately 10 to 24 hours postdose for DM-3411.  
In healthy subjects, administration of single-dose brexpiprazole with a high-fat meal did 
not affect its rate and extent of absorption.
Steady-state pharmacokinetics also appeared to be linear following multiple daily doses 
of brexpiprazole in the range of 0.5 to 2 mg to healthy subjects.  The accumulation ratio, 
based on the maximum (peak) plasma concentration (Cmax) and area under the 
concentration-time curve calculated to the last observable concentration at time t (AUCt),

was approximately 4 times.  After multiple-dose administration of brexpiprazole 
(1-12 mg/day) to subjects with schizophrenia or schizoaffective disorder, the mean 
terminal elimination half-life of brexpiprazole and DM-3411 at steady state was 95.4 and 
89.3 hours, respectively; and the median tmax was 3.0 and 8.0 hours, respectively.
In drug interaction trials in healthy subjects, brexpiprazole was shown to be metabolized 
by the cytochrome P450 3A4 (CYP3A4) and 2D6 (CYP2D6) isozymes and was not an 
inhibitor of CYP3A4, CYP2B6, CYP2D6, or P-glycoprotein.  Coadministration of potent 
CYP3A4 or CYP2D6 inhibitors with brexpiprazole resulted in about a 2-fold higher 
exposure and about a 1.5-fold increase in the terminal elimination half-life of 
brexpiprazole.
In a single-dose trial in healthy subjects, approximately 46.0% and 24.6% of 
administered radioactivity following an oral dose of 14C-brexpiprazole was excreted in 
feces and urine, respectively.  In this same trial, brexpiprazole did not preferentially bind 
to red blood cells (RBCs).  Brexpiprazole showed high protein binding in human serum 
(99.8%) in vitro.
The binding of brexpiprazole to dopamine receptors was assessed using positron 
emission tomography (PET).  The mean D2/D3 receptor occupancies at 4 and 24 hours 
postdose after single-dose administration of 0.25, 0.5, 1, 2, 4, 5, and 6 mg of 
brexpiprazole to healthy subjects were 11.4% to 17.4%, 36.5% to 46.3%, 45.6% to 
60.2%, 52.7% to 68.6%, 67.9% to 79.5%, 71.9% to 88.2%, and 69.5% to 92.6%, 
respectively (Trial 331-07-202).  Based on the single-dose D2/D3 receptor occupancy 
data and steady-state pharmacokinetic and pharmacodynamic modeling, it was predicted 
that the D2/D3 receptor occupancy after multiple daily dose administration of 1 to 2 mg
and higher doses of brexpiprazole will result in at least 80% to 90% D2/D3 receptor 
occupancy.
Trials have investigated the pharmacokinetics of brexpiprazole in special populations 
(subjects with hepatic impairment and renal impairment); one studying the effects of age 
and sex on brexpiprazole pharmacokinetics has been completed.  Based on the results of 
the special population trials, no dose adjustment is needed when brexpiprazole is 
administered to elderly subjects or subjects with renal or hepatic insufficiency.
Additional information on the pharmacokinetics and pharmacodynamics of brexpiprazole 
and its metabolites in humans can be found in the Investigator’s Brochure.16

Major Depressive Disorder (MDD)
The use of brexpiprazole as adjunctive therapy for the treatment of MDD has been 
studied in 2 completed, phase 2, double-blind, placebo-controlled trials (Trials 
331-08-211 and 331-09-222).  Additionally, 6 studies are ongoing: 2 United States (US)
trials (1 phase 1, randomized, double-blind, placebo-controlled trial in elderly adults 
[aged 70-80 years] with MDD [Trial 331-12-291]; 1 long-term, open-label safety trial 
[Trial 331-08-212]); and 4 multinational trials (2 randomized, double-blind, 
placebo-controlled trials [Trials 331-10-227 and 331-10-228]; 1 randomized, 
double-blind, placebo- and active comparator-controlled trial of flexible-dose 
brexpiprazole as adjunctive therapy in the treatment of adults with MDD 
[Trial 331-12-282];  and 1 open-label, 52-week safety trial [Trial 331-10-238]).
Trial 331-08-211 was a multicenter, randomized, double-blind, placebo-controlled trial 
designed to assess the safety and efficacy of brexpiprazole (0.15 to 2 mg daily) as 
adjunctive treatment to an assigned open-label antidepressant therapy (ADT) in subjects 
with MDD.  Subjects received brexpiprazole 0.15 mg/day, 0.50 0.25 mg/day, 
1.5 0.50 mg/day, or matching placebo.  In this trial, adjunctive brexpiprazole dosed at 
1.5 0.50 mg/day was superior to adjunctive placebo with respect to the primary 
endpoint (change in Montgomery Asberg Depression Rating Scale [MADRS] Total 
Score) and several secondary efficacy endpoints.  The 1.5 0.50 mg/day brexpiprazole 
dose group also demonstrated a favorable safety profile.  Few subjects experienced 
serious treatment-emergent adverse events (TEAEs) or discontinued due to TEAEs.  The 
analysis of laboratory data, electrocardiogram (ECG) parameters, and EPS scales did not 
indicate any concerns of clinical significance.
In Trial 331-09-222, randomized subjects received a flexible dose of brexpiprazole 1 to 
3 mg/day (average dose 2.2 mg/day) or placebo as adjunctive treatment to an assigned 
open-label ADT.  In this trial, the MADRS Total Score decreased at each visit for both 
brexpiprazole and placebo groups, however, the decrease observed in the brexpiprazole 
group was statistically significant from baseline at all visits except the primary endpoint 
visit.  The MADRS response rate (≥ 50% decrease MADRS Total Score) and remission 
rate (MADRS Total Score ≤ 10) were statistically significant at endpoint.  Brexpiprazole 
at doses up to 3 mg/day was well tolerated when administered as adjunctive therapy to a 
marketed ADT in subjects with MDD.  During the double-blind treatment phase, TEAEs 
were reported in 76.2% of subjects in the brexpiprazole group and 63.6% of subjects in

the placebo group.  The most frequently reported TEAEs were akathisia (11.9%), 
increased weight (11.4%), and insomnia (9.2%).  The Columbia-Suicide Severity Rating 
Scale (C-SSRS) and adverse event (AE) data showed no suicidal behavior during 
double-blind treatment.  No serious adverse events (SAEs) were reported for subjects in 
the brexpiprazole group, and 3 subjects (1.6%) in the placebo group experienced an SAE; 
4.9% of subjects who received adjunctive brexpiprazole and 1.1% of subjects who 
received adjunctive placebo discontinued treatment due to TEAEs.  There were no 
clinically relevant changes in laboratory values, ECG parameters, or vital sign 
measurements, except body weight (mean increase of 1.92 kg in the brexpiprazole group 
versus 0.13 kg in the placebo group), in brexpiprazole-treated subjects.  The minimal 
changes in scores for EPS scales during double-blind treatment were not clinically 
relevant.  An EPS-related AE was observed in 21.6% of subjects in the brexpiprazole 
group compared with 9.6% of subjects in the placebo group.
Trial 331-08-212 is an ongoing, 52-week, open-label trial examining the long-term safety 
and tolerability of brexpiprazole in adults with MDD.  Subjects who complete trials 
331-08-211 or 331-09-222 are eligible to enter this trial.
Ongoing Trials 331-10-227 and 331-10-228 are phase 3, multicenter, randomized, 
double-blind, placebo-controlled, fixed-dose trials designed to assess the safety and 
efficacy of brexpiprazole as adjunctive therapy to an assigned open-label marketed ADT 
in depressed subjects who have demonstrated an incomplete response to prospective 
treatment with the same ADT.  Brexpiprazole doses evaluated in these trials include 
1 and 3 mg/day in Trial 331-10-227 and 2 mg/day in Trial 331-10-228.  Subjects who 
complete Trial 331-10-227 or Trial 331-10-228 are eligible to be enrolled into a 
multicenter, 52-week, open-label trial (Trial 331-10-238).  The ongoing trial 331-12-282 
is a phase 3, multicenter, randomized, double-blind, placebo- and active comparator 
(Seroquel XR)-controlled trial designed to assess the safety and efficacy of flexible-
dose brexpiprazole as adjunctive therapy to an assigned open-label ADT in depressed 
adults, aged 18 to 65 years.  The ongoing trial 331-12-291 is a phase 1, multicenter, 
randomized, double-blind, placebo-controlled trial designed to assess the safety and 
tolerability of multiple ascending oral doses of brexpiprazole as adjunctive therapy in the 
treatment of elderly subjects (70 to 85 years) with MDD.

Schizophrenia
The use of brexpiprazole monotherapy for the treatment of schizophrenia has been 
studied in 2 completed, multinational, phase 2, double-blind, placebo-controlled trials 
(Trials 331- 07-203 and 331-08-210). In addition, 4 multinational, phase 3 trials are 
ongoing:  3 randomized, double-blind, placebo-controlled trials (Trials 331-10-230, 
331-10-231, and 331-10-232) and 1 open-label, 52-week safety trial (Trial 331-10-237).
Trial 331-07-203 was a dose-ranging, placebo-controlled trial (with aripiprazole as a 
positive control to confirm the assay sensitivity of the trial) in subjects experiencing an 
acute exacerbation of schizophrenia.  Although the results showed that neither 
brexpiprazole (dose range, 0.25-6 mg/day) nor aripiprazole was significantly different 
from placebo for the primary and secondary efficacy endpoints at Week 6 
(last-observation-carried-forward [LOCF]), numeric improvements in efficacy scale 
scores were similar between the low, mid, and high flexible-dose groups of brexpiprazole 
and aripiprazole for several endpoints, including the primary endpoint (the Positive and 
Negative Syndrome Scale [PANSS] total score, which measures the severity of 
symptoms of schizophrenia).  Factors such as sex, age, and race did not appear to have a 
consistent influence on efficacy outcomes; however, the small sample size in many of the 
subgroup categories precluded definitive conclusions.  The collective efficacy data from 
this trial suggest an active dose range of 1 to 6 mg/day of brexpiprazole for the treatment 
of schizophrenia.  The frequency of TEAEs was similar in the brexpiprazole (69.7%), 
placebo (70.5%), and aripiprazole (70.0%) groups.  The frequency of SAEs was similar 
between the brexpiprazole (3.8%) and placebo (3.2%) groups.  The C-SSRS and AE data 
showed no suicidal behavior during double-blind or open-label treatment.  Brexpiprazole 
did not result in any consistent, clinically relevant changes in laboratory values, vital 
signs, or ECG parameters.  Statistically significant increases in weight, body mass index 
(BMI), and waist circumference were observed in the 2.5 ± 0.5 mg/day and 
5.0 ± 1.0 mg/day brexpiprazole groups compared with the placebo group.
Eligible subjects from Trial 331-07-203 could have continued into the multicenter, 
52-week, open-label trial (Trial 331-08-210) designed to assess the safety and tolerability 
of 1 to 6 mg of oral brexpiprazole in adult subjects with schizophrenia.  Twenty-eight 
subjects were included in the 52-week trial: 20 subjects who had received prior 
brexpiprazole, 6 who had received prior placebo, and 2 who had received prior 
aripiprazole.  Assessment of efficacy as a secondary objective showed improvement from 
baseline for each of the efficacy endpoints.  The response rate (reduction of ≥ 30% from 
baseline in PANSS total score or CGI-I score of 1 [very much improved] or 2 [much

improved] at the last visit) was 35.2% (86 of 244 subjects).  Further, discontinuation for 
lack of efficacy was infrequent (2.0% [5 of 244 subjects]).  Brexpiprazole (1-6 mg/day) 
was well tolerated when administered for up to 52 weeks.  During the trial, 75.0% (21 of 
28) of subjects enrolled for 52 weeks reported at least 1 TEAE.  Most TEAEs were mild 
or moderate in intensity.  The most frequently reported TEAEs (ie, those reported in 
> 10% of subjects) were viral respiratory tract infection and increased weight (14.3% 
each) and nasopharyngitis and somnolence (10.7% each).  Although there were isolated, 
potentially clinically relevant results for individual subjects in clinical laboratory, vital 
signs, and/or ECG assessments, there were no clinically relevant mean changes overall 
for these assessments.  Brexpiprazole was associated with slight mean increases from 
baseline in body weight, BMI, and waist circumference.  Overall, the long-term safety 
and tolerability of brexpiprazole appeared to be similar to that observed after short-term 
exposure (up to 6 weeks); however, this could not be fully characterized in this trial due 
to the small number of subjects exposed for 52 weeks.
Currently, ongoing Trials 331-10-230 and 331-10-231 are designed to assess the safety 
and efficacy of fixed doses of 1, 2, or 4 mg/day of brexpiprazole and 0.2, 2, and 4 mg/day 
of brexpiprazole, respectively, in adults with acute schizophrenia; and Trial 331-10-232 
will evaluate the use of brexpiprazole (1-4 mg/day) as maintenance treatment in subjects 
with schizophrenia.  Subjects who complete Trial 331-10-230, Trial 331-10-231, or 
Trial 331-10-232 are eligible to be enrolled into a multicenter, 52-week, open-label trial 
(Trial 331-10-237), along with de novo subjects from select sites.

Attention-Deficit/Hyperactivity Disorder (ADHD)
For ADHD, 1 phase 2 trial (Trial 331-08-213) has been completed.  Trial 331-08-213 was 
a proof-of-concept, multicenter, randomized, double-blind, placebo-controlled, 
flexible-dose trial in which adults with ADHD who had an incomplete/partial response to 
stimulant therapy in a prospective treatment phase were randomized to double-blind 
treatment with either brexpiprazole-plus-stimulant or placebo-plus-stimulant.  Results 
showed no statistically significant improvement in the brexpiprazole group compared 
with the placebo group with regard to the primary efficacy endpoint (ie, the Conners’ 
Adult ADHD Rating Scale-Observer:  Screening Version [CAARS-O:SV]), the key 
secondary efficacy endpoints (ie, Wender-Reimherr Adult Attention Deficit Disorder 
Scale [WRAADDS] total score and sleep improvement as measured by the Insomnia 
Severity Index [ISI] total score and the ISI Item 2) or other efficacy endpoints.  During

reported at least 1 TEAE.  Only insomnia (in 13 of 155 [8.4%] subjects) and headache (in 
11 of 155 [7.1%] subjects) were reported in greater than 5% of subjects in the 
brexpiprazole group.  Most TEAEs were mild or moderate in intensity.  During the 
double-blind treatment phase, 2 subjects reported SAEs (pneumonia and urinary tract 
infection), both of whom were in the placebo group.  There were no unexpected or 
clinically relevant findings related to assessments of movement disorders, metabolic 
syndrome, EPS rating scales, or suicidality (based on the C-SSRS) during the 
double-blind phase.
1.3.
Known and Potential Risks and Benefits
Based on the Investigator’s Brochure,16 combined data from the completed phase 1 
clinical trials indicate that brexpiprazole is safe and well tolerated in healthy subjects at 
single oral doses of 0.2 to 6 mg and at multiple oral doses up to 2 mg/day.  Data from the 
completed multiple-dose clinical trials indicate brexpiprazole is well tolerated at multiple 
oral doses up to 12 mg/day in subjects with schizophrenia or schizoaffective disorder; up 
to 4 mg/day when coadministered with marketed ADT in subjects with MDD; and up to 
4 mg/day when coadministered with marketed stimulant therapy in subjects with ADHD. 
Based on data from the 18 completed phase 1 clinical trials in healthy subjects or special


MDD (N = 3 trials):  akathisia, increased weight, insomnia, upper respiratory tract 
infection, and nasopharyngitis

ADHD (N = 2 trials):  insomnia
In the single completed phase 1 trial in subjects with schizophrenia conducted in Japan, 
TEAEs reported in 3 or more subjects who received brexpiprazole (of 21 total subjects) 
were:

Schizophrenia (N = 1 trial): increased serum prolactin and increased serum creatine 
phosphokinase
Brexpiprazole did not result in any consistent, clinically relevant changes in laboratory 
values, vital signs (blood pressure or heart rate), or ECG parameters in the completed 
phase 1 and 2 clinical trials in subjects with MDD or schizophrenia.  Statistically 
significant increases in weight were observed with brexpiprazole relative to placebo in 
both sample populations.  Brexpiprazole exhibited a favorable profile with respect to 
movement disorders in subjects with MDD at doses up to 3 mg/day (Trial 331-09-221) 
and in subjects with schizophrenia at doses up to 12 mg/day (Trial 331-08-205).  In the 
dose-ranging trial that enrolled subjects who were experiencing an acute exacerbation of 
schizophrenia (Trial 331-07-203), an increase in the incidence of EPS was observed at
the highest dose (ie, brexpiprazole 5 1 mg/day).
Two deaths have been reported in the 30 completed clinical trials.  One death was 
reported in the completed phase 2 double-blind trial in adult subjects with acute 
schizophrenia (Trial 331-07-203).  The second death was reported in the completed 
phase 2 open-label MDD trial (Trial 331-08-212).  None of these subjects were taking 
IMP at the time of death and none of these fatal events were considered by the 
investigator to be related to IMP.  Additionally, 4 deaths have been reported in 2 ongoing 
phase 3 open-label trials of brexpiprazole.  One death was reported in an ongoing 
schizophrenia trial (331-10-237) and 3 deaths were reported in an ongoing MDD trial 
(331-10-238).  One of the deaths (completed suicide in Trial 331-10-238) was considered 
by the investigator to be possibly related to IMP.
Serious TEAEs have been reported for 64 subjects who received brexpiprazole in the 
30 completed trials.  In ongoing trials of brexpiprazole, 120 subjects receiving 
brexpiprazole had reported serious TEAEs.

2. Trial Rationale and Objectives
2.1.
Trial Rationale
Behavioral symptoms, such as agitation, are core features in subjects with Alzheimer’s 
disease and related dementias and develop in the majority of dementia subjects.  The 
presence of agitation in subjects with Alzheimer’s disease places a significant burden not 
only on subjects and their caregivers but also on the healthcare system.
Based on the data available from atypical antipsychotics in the treatment of agitation or 
aggression in Alzheimer’s disease, brexpiprazole is an appropriate candidate to evaluate 
the benefit-risk ratio of this class of drugs in this subject population in today’s clinical 
setting.  In addition to potential treatment effects, the receptor binding profile of 
brexpiprazole may confer additional benefits in terms of the safety profile, particularly 
with respect to hyperprolactinemia, sleep quality, and weight gain.
In light of the Food and Drug Administration (FDA) boxed warning of increased 
mortality with the use of antipsychotics in elderly subjects with dementia-related 
psychosis and similar caution advised by other regulatory authorities, the clinical trial 
will be conducted in an environment that allows for close safety monitoring, in subjects
who are living in either an institutionalized setting or in a non-institutionalized setting 
where the subject is not living alone and has a caregiver who can spend a minimum of 
2 hours per day for 4 days per week with the subject in order to assess changes in the 
subject’s condition.  Furthermore, a slow titration schedule will be implemented with 
brexpiprazole being titrated to the highest assigned dose (2 mg/day) over a 4-week 
period.  
 
 
 
2.2.
Dosing Rationale
Doses of brexpiprazole 1 mg/day and 2 mg/day will be studied in this fixed-dose trial.  
Doses will be increased slowly so that the highest dose will be reached at end of the 
fourth week of treatment (ie, at the Week 4 visit).
The doses to be used in this indication have been determined based on results from 
completed phase 1 safety and tolerability trials; from a PET trial of dopamine receptor 
occupancy; from phase 2 and phase 3 trials in subjects with schizophrenia, MDD, or 
ADHD; and from review of data from trials of similar medications in subjects with

dementia.  The following doses of brexpiprazole have been well tolerated in completed 
phase 1 single- and multiple-ascending-dose clinical trials:

Up to 6 mg from single-dose trials and up to 2 mg/day from multiple-dose trials in 
healthy subjects

Up to 12 mg/day from multiple-dose trials in subjects with schizophrenia or 
schizoaffective disorder (the maximum tolerated dose [MTD] was not reached)

Up to 4 mg/day from a multiple-dose trial in subjects with MDD when 
coadministered with marketed ADT (the MTD was not reached)

Up to 4 mg/day from a multiple-dose trial in subjects with ADHD when 
coadministered with marketed stimulant therapy (the MTD was not reached)
In the multiple-ascending-dose studies of subjects with schizophrenia, MDD, and ADHD, 
the studies ended when a prospectively chosen daily dose was reached.  In all 3 studies, 
the MTD was not reached.  The MTD of brexpiprazole in subjects with schizophrenia is 
greater than 12 mg/day.  The MTD in subjects with MDD and ADHD, when 
coadministered with ADT and stimulant therapy, respectively, is greater than 4 mg/day.  
These data indicate that doses of at least 4 mg/day are well tolerated in nonpsychotic 
adult psychiatric subjects.
Efficacy in treating schizophrenia by dopamine D2 antagonists has been associated with 
occupancy of greater than 65% of the dopamine receptors.17,18,19  However, the 
occupancy associated with effective doses of another partial dopamine agonist, 
aripiprazole, are greater than 80%20,21 and the occupancy associated with therapeutic 
benefit of the brexpiprazole would be expected to be in the same range.  To further define 
the proper dose range for brexpiprazole, the binding of brexpiprazole to dopamine D2/D3 
receptors was investigated in a PET trial in healthy subjects (Trial 331-07-202).  Single 
doses of up to 6 mg of brexpiprazole were administered to 15 subjects.  Results from the 
trial predicted steady-state receptor occupancies of 80% to 90% at brexpiprazole doses of 
1 to 2 mg (79.3% predicted occupancy at 1 mg brexpiprazole, 88.8% at 2 mg
brexpiprazole, and 95.1% at 4 mg brexpiprazole).  Based on the single-dose D2/D3 
receptor occupancy data and steady-state pharmacokinetic/pharmacodynamic modeling, 
it was predicted that the D2/D3 receptor occupancy after multiple daily dose 
administration of 1 mg to 2 mg doses would result in 80% to 90% D2/D3 receptor 
occupancy.

  Since 4 mg/day has been well tolerated and to ensure 
that D2 occupancy levels at and above 80% are achieved, doses up to 4 mg/day are being 
studied in the phase 3 trials in schizophrenia and up to 3 mg/day in adjunctive treatment 
of MDD.  In the phase 2 trial of adults with ADHD, the highest dose was 3 mg/day.
Three studies of another compound discovered by Otsuka, aripiprazole (Abilify), have 
been conducted to investigate its benefit in the treatment of psychosis in subjects with 
Alzheimer’s dementia.21,22,23  In the 2 of the 3 aripiprazole trials that were conducted in 
subjects in institutional settings such as nursing homes, benefit in the treatment of 
agitation in that subject population was suggested by the finding of statistically 
significant differences between the aripiprazole treatment groups and the placebo 
treatment groups on 2 secondary endpoints, the Cohen-Mansfield Agitation Inventory 
(CMAI) and the agitation item of the Neuropsychiatric Inventory-Nursing Home 
(NPI-NH).  In the fixed dose trial, which included 2 mg/day, 5 mg/day, and 10 mg/day 
dose arms, there were significant differences found on both measures for the 5 mg/day 
and 10 mg/day groups.  Significant differences compared with placebo on both measures 
were also observed in the second flexible-dose trial of the 2 mg/day to 15 mg/day dose 
range.
Because of concerns about tolerability and safety in subjects, the doses of antipsychotics 
used in clinical trials in subjects with dementia have generally been lower than the doses 
recommended for subjects with schizophrenia.21,22,24  While the dose range for 
brexpiprazole in schizophrenia studies is 1 mg/day to 4 mg/day, the selected dose range 
in the Alzheimer’s population is 1 mg/day to 2 mg/day, to maximize tolerability while 
investigating doses that should achieve the occupancy of the D2 receptor associated with 
benefit in the alleviation of target symptoms by a D2 partial agonist.  Slow titration of the 
dosing will also be employed to maximize tolerability.
2.3.
Trial Objectives
Primary:
To compare the efficacy of 2 fixed doses (1 mg/day and 2 mg/day) of 
brexpiprazole with placebo in subjects with agitation associated with 
dementia of the Alzheimer’s type, as assessed by the CMAI after 12 weeks of 
treatment.

Secondary: To evaluate the safety and tolerability of 2 fixed doses of brexpiprazole 
(1 mg/day and 2 mg/day) compared with placebo in subjects with agitation 
associated with dementia of the Alzheimer’s type after 12 weeks of 
treatment.
3. Trial Design
3.1.
Type/Design of Trial
This is a phase 3, 12-week, multicenter, randomized, double-blind, placebo-controlled, 
3-arm, fixed-dose trial designed to assess the efficacy, safety, and tolerability of 
brexpiprazole (1 mg/day and 2 mg/day) in the treatment of subjects with agitation 
associated with dementia of the Alzheimer’s type.  The trial population will include male 
and female subjects between 55 and 90 years of age (inclusive), who are living in either 
an institutionalized setting or in a non-institutionalized setting where the subject is not 
living alone. In both the institutionalized and non-institutionalized settings, the subject 
must have a caregiver who can spend a minimum of 2 hours per day for 4 days per week 
with the subject in order to assess changes in the subject’s condition. All subjects must 
have a diagnosis of probable Alzheimer’s disease according to the National Institute of 
Neurological and Communicative Disorders and Stroke and the Alzheimer’s Disease and 
Related Disorders Association (NINCDS-ADRDA) criteria.  
The trial comprises a 2- to 42-day screening period, a 12-week double-blind treatment 
period, and a 30-day post-treatment follow-up period.  
 
 
    
This trial will be monitored under the supervision of an independent Data Monitoring 
Committee (DMC).  The DMC will monitor safety periodically, based on a 
predetermined schedule.  The details of the DMC structure and its roles and 
responsibilities will be documented in a DMC Charter (refer to Section 3.7.8).
The trial is organized as follows (refer to Figure 3.1-1 for a schematic of the trial design):
Screening Period
The screening period will range from 2 days to 42 days and will begin when the informed 
consent form (ICF) is signed, prior to the initiation of any procedures.  The screening 
period may be extended after discussion with and approval by the medical monitor.  
Additional requirements for obtaining informed consent from this vulnerable subject 
population are provided in Section 3.4.1. An interactive voice response system (IVRS) or

interactive web response system (IWRS) will be used to obtain the subject trial
identification number for each subject with a signed ICF.
The purpose of the screening period is to determine the subject’s eligibility and to 
washout prohibited concomitant pharmacotherapy prior to randomization (refer to 
Section 4.1).  The subject should be randomized into the double-blind treatment period as 
soon as all the screening assessments are completed, the screening and baseline eligibility 
criteria have been met, and the required washout period has occurred.
 
 
 
  The investigator is responsible for ensuring that subjects are 
eligible for enrollment into the trial and for assessing subject safety throughout the trial.  
 
In addition, starting at screening and continuing throughout the 12-week double-blind 
treatment period, the subject’s behavior will be logged into a diary by the caregiver 
and/or facility staff.  This diary data along with the collection of progress notes will be 
sent to the 
 on a routine basis in order to corroborate information recorded on 
the CMAI.  Since the diary data is a tool to assist 
 in monitoring CMAI rater 
training, the diary data will not be statistically analyzed.
While it is preferred that diary data are collected 7 days a week, it is realized that diary 
use for 7 days a week may not be possible because the minimum amount of time that the 
caregiver is required to observe the subject is 4 days a week.  Every effort should be put 
forth by the sites to encourage the caregivers to collect and submit as much data as 
possible.  Caretakers, facility personnel, and/or family members may provide information 
to the caregiver to complete the diary, but this is not a requirement.
Details around this procedure can be found in the operations manual.
12-week, Double-blind Treatment Period
Based on a randomization scheme, eligible subjects will be allocated in a 1:1:1 ratio at 
randomization to 1 of the following 3 treatment groups:

Brexpiprazole 1 mg/day

Brexpiprazole 2 mg/day

Placebo

Subjects will follow a titration schedule, depending upon their assigned treatment group, 
to gradually increase their dose of the IMP to their assigned target dose (refer to
Table 3.2-1).  
Subjects unable to tolerate their assigned dose of brexpiprazole (or matching placebo) 
will be withdrawn from the trial.  Down-titration is not allowed at any time during the 
trial. If a subject is withdrawn, every effort will be made to complete all of the 
Week 12/Early Termination (ET) evaluations prior to administering any additional 
medications for the treatment of agitation or other prohibited medications.
Subjects will be evaluated at Baseline, Day 3, and at Weeks 2, 4, 6, 8, 10, and 12 during 
the double-blind treatment period. All trial visits will take place as a clinic visit at either 
the investigator’s site or residential facility, if applicable.  All attempts should be made 
to maintain the subjects’ normal routine with regard to physician appointments.  
Individual circumstances that fall outside this general convention should be discussed 
with the medical monitor in order to determine appropriateness to proceed.  In 
addition, the subject’s identified caregiver will be contacted by telephone at Weeks 3, 5, 
and 7 to assess compliance with IMP, confirm any changes to concomitant medications, 
and assure the subject’s well-being.  Trial-related efficacy and safety assessments will 
be performed as outlined in the Schedule of Assessments (Table 3.7-1).  
Follow-up Period
All subjects, whether they complete the trial or are withdrawn prematurely for any 
reason, will be followed up for a safety evaluation 30 (+ 2) days after the last dose of 
IMP during a clinic visit at either the investigator’s site or residential facility, if 
applicable.  If a clinic visit is not possible, the subject should be assessed by telephone 
contact with the subject and a caregiver.  
 
 
Subjects who complete both the 12-week double-blind treatment period and the 30-day 
safety follow-up visit are eligible to enroll into Trial 331-13-211, which is a 2-month, 
observational, rollover trial to evaluate the safety of subjects with agitation associated 
with Alzheimer's disease who previously participated in Trial 331-12-283. For those 
subjects who plan to enroll into Trial 331-13-211, the 30-day safety follow-up visit for 
Trial 331-12-283 will occur as a clinic visit either at the investigator’s site or residential 
facility, if applicable.

Treatments
Treatment assignments will be obtained by accessing the IVRS or IWRS.  Based on the 
fixed-block, computer-generated randomization, eligible subjects will be allocated in a 
1:1:1 ratio at randomization to 1 of the following 3 treatment groups:

Brexpiprazole 1 mg/day

Brexpiprazole 2 mg/day

Placebo
Neither the investigator nor the subject will be aware of the treatment assignment.  All 
doses of brexpiprazole and matching placebo should be taken orally once daily,
preferably in the morning, and can be administered without regard to meals.  
Brexpiprazole should be taken at approximately the same time each day, particularly 
prior to visits with pharmacokinetic sampling.
Subjects will follow a titration schedule, depending upon their assigned treatment group, 
to gradually increase their dose of the IMP to their assigned target dose as follows:

Subjects will remain on this dose until Week 12/ET (the last day of the Treatment 
Period).
For subjects randomly assigned to receive placebo, their dose of IMP will be 
administered daily starting on the day after the Baseline visit (ie, Day 1) and ending on 
Week 12/ET (the last day of the Treatment Period).
Subjects unable to tolerate their assigned dose of brexpiprazole (or matching placebo) 
will be discontinued from the trial.  Down-titration is not allowed at any time during the 
trial.  
3.3.
Trial Population
The subject population will include male and female subjects between 55 and 90 years of 
age (inclusive), who are living in either an institutionalized setting or in a non-
institutionalized setting where the subject is not living alone. In both the institutionalized 
and non-institutionalized settings, the subject must have a caregiver who can spend a 
minimum of 2 hours per day for 4 days per week with the subject in order to assess 
changes in the subject’s condition. All subjects must have a diagnosis of probable 
Alzheimer’s disease according to the NINCDS-ADRDA criteria.  Subjects must have a 
previous magnetic resonance imaging (MRI) or computed tomography (CT) scan of the 
brain, which was performed after the onset of symptoms of dementia, with findings
consistent with a diagnosis of Alzheimer’s disease. If a previous MRI or CT scan of the 
brain performed after the onset of the symptoms of dementia is not available, then an

MRI/CT scan should be performed during screening.  Additionally, at both the screening 
and baseline visits, subjects must have a Mini-Mental State Examination (MMSE) score 
of 5 to 22, inclusive, and a total score (frequency × severity) of ≥4 on the 
agitation/aggression item of the NPI-NH or the Neuropsychiatric Assessment for 
Non-institutionalized Patients based on the NPI/NPI-NH (hereafter referred to as 
“NPI/NPI-NH”). The NPI-NH will be used for institutionalized subjects and the 
NPI/NPI-NH will be used for non-institutionalized subjects.  The onset of the subject’s 
symptoms of agitation must be at least 2 weeks prior to the screening visit.  Subjects must 
require pharmacotherapy for the treatment of agitation per the investigator’s judgment, 
after an evaluation for reversible factors (eg, pain, infection, polypharmacy) and a trial of 
nonpharmacological interventions.
Subjects must have been residing at their current location for at least 14 days before 
screening and be expected to remain at the same location for the duration of the trial.  
Subjects who at any point during the double-blind treatment phase transfer from an 
institutionalized setting to a non-institutionalized setting, or vice versa, will be withdrawn 
from the trial.  In case of a brief hospitalization, determination of subject eligibility to 
stay in the trial must be made based on subject safety by the investigator and medical 
monitor.  All attempts should be made to maintain the subjects’ normal routine with 
regard to appointments with physicians and overnight accommodations.  Subjects in an 
institutionalized setting may receive supervised day passes at the discretion of the 
investigator and may also receive supervised overnight passes at the discretion of the 
investigator as long as such overnight stays are part of the subjects’ normal routine.  
 
 
 
It is planned that approximately 840 subjects will be screened at approximately 85 trial 
sites worldwide in order to randomize approximately 420 subjects.

Non-institutionalized Subjects 
In a non-institutionalized setting, the subject’s caretaker is the person who lives with and 
cares for the subject on a regular basis.  For example, caring for a subject on a regular 
basis may include the following activities:  assisting with dispensing of IMP; observing

reducing the chance of fall; and assisting the subject if emergency medical care is needed 
by contacting appropriate emergency services, the subject’s primary physician, or the 
principal investigator, whatever is warranted.  The caretaker may be supported in 
providing care to the subject by a professional(s), friend(s), or family member(s).
For purposes of this trial, the subject’s caregiver is defined as the person who has 
sufficient contact to describe the subject’s symptoms, and has direct observation of the 
subject’s behavior in order to participate in the interview for the CMAI, NPI/NPI-NH, 
and other applicable trial assessments, including completion of the diary.  A caregiver 
must be identified during the screening period for participation in the interview of the 
applicable trial assessments.  At the time of the subject’s screening visit, the caregiver 
will be provided a document that will outline all caregiver responsibilities.  The caregiver 
should acknowledge and agree to undertake all the tasks designated by this protocol at the 
time of the informed consent process.  The caregiver role in the non-institutionalized 
setting may or may not be the same individual who fulfills the role of caretaker 
depending on the circumstances of the subject.  The recommended minimum level of 
contact between the caregiver and the subject is 2 hours per day for 4 days per week.  The 
caregiver is the person who should accompany the subject to all visits where the CMAI 
and NPI/NPI-NH are administered unless other arrangements are made and approved by 
the sponsor.
3.3.1.2.
Institutionalized Subjects 
In the institutionalized setting, there is only one role defined and that is the role of 
caregiver.  A caregiver in the institutionalized setting is an individual who has sufficient 
contact to describe the subject’s symptoms and who has direct observation of the
subject’s behavior in order to participate in the interview for the CMAI, NPI-NH, and 
other applicable trial assessments.  A caregiver must be identified during the screening 
period for participation in the interview of the applicable trial assessments.  At the time of 
the subject’s screening visit, the caregiver will be provided a document that will outline 
all caregiver responsibilities.  The caregiver should acknowledge and agree to undertake 
all the tasks designated by this protocol at the time of the informed consent process.  The 
identified caregiver can be a staff member of the institutionalized setting or another 
individual (eg, family member, family friend, hired professional caregiver) who meets the 
caregiver requirements.  The recommended minimum level of contact between the 
caregiver and the subject is 2 hours per day for 4 days per week.

Informed Consent
3.4.1.1.
Determinations of Capacity
The investigator must assess the capacity of the subject to provide informed consent 
during the screening period and throughout the course of the trial.  This assessment will 
be made in accordance with the investigator’s standard practice.  Once these
determinations are made by the investigator, the following options for obtaining informed 
consent from and/or on behalf of the subject must be followed:

If the subject is deemed capable by the investigator, written informed consent will be 
obtained from the subject prior to the initiation of any trial protocol-required 
procedures.  In such cases, acknowledgement from the subject’s legally acceptable 
representative (an individual, or judicial or other body, authorized under applicable 
law to consent to the subject’s participation in the clinical trial on behalf of that
prospective subject) will also be obtained, if required, in accordance with state and/or 
local regulations prior to initiation of any trial protocol-required procedures.   

If the subject is deemed incapable by the investigator of providing consent (eg,
subjects with severe dementia), written informed consent will be obtained from the 
subject’s legally acceptable representative prior to initiation of any trial
protocol-required procedures.  In such cases, assent from the subject, if possible, will 
be confirmed in accordance with state and/or local regulations prior to the initiation 
of any trial protocol-required procedures. 

If the subject cannot provide assent, and does not dissent, then the consent of the 
legally acceptable representative is sufficient unless otherwise required by the 
governing ethics body and/or applicable state and/or local regulations.

If the subject dissents, then the subject is not eligible for participation in the trial.

If the subject initially provided assent at trial entry, but subsequently dissents to 
participate in the trial, the subject will be early terminated from the trial. 

If the subject was initially deemed capable of providing informed consent but is no 
longer deemed so, informed consent must be obtained from the subject’s legally 
acceptable representative, and assent from the subject, if possible, will be confirmed 
in accordance with state and/or local regulations prior to the initiation or continuation 
of any trial protocol-required procedures.

Documentation of Informed Consent
Consent will be documented on a written ICF.  The ICF will be approved by the same 
institutional review board (IRB)/independent ethics committee (IEC) that approves this 
protocol.  Each ICF will comply with the International Conference on Harmonization 
(ICH) Good Clinical Practice (GCP) Guideline25 and local regulatory requirements.  The 
investigator agrees to obtain sponsor approval of any written ICF used in the trial prior to 
submission to the IRB/IEC.
Investigators may discuss trial availability and the possibility for entry with a potential 
subject and subject’s legally acceptable representative without first obtaining consent.  
However, informed consent must be obtained and documented prior to initiation of any 
procedures that are performed solely for the purpose of determining eligibility for this 
trial, including withdrawal from current medication(s). The subject must be informed 
about the trial to the extent compatible with the subject’s understanding and, if capable, 
personally sign and date the consent or assent form, depending on local regulations.
If the subject or subject’s legally acceptable representative is unable to read or sign due to 
physical limitations, an impartial witness should be present during the entire informed 
consent discussion.  After the subject’s legally acceptable representative and subject 
orally consent and have signed, if capable, the witness should sign and personally date 
the consent and/or assent form attesting that the information is accurate and that the 
subject’s legally acceptable representative and subject understand and have freely given 
consent.
The informed consent and any other information provided to the subject and the subject’s 
legally acceptable representative should be revised whenever important new information 
becomes available that is relevant to the consent, and should receive IRB/IEC approval 
prior to use.  The investigator (or qualified designee) should fully inform the subject and 
the subject’s legally acceptable representative of all pertinent aspects of the trial and of 
any new information relevant to the willingness of the subject and the subject’s legally 
acceptable representative to continue participation in the trial. This communication 
should be documented.
Once appropriate essential information has been provided and fully explained in 
layman’s language to the subject and the subject’s legally acceptable representative by 
the investigator (or a qualified designee), the IRB/IEC-approved written ICF will be 
signed and dated by the subject, if capable, or the subject’s legally acceptable 
representative and the person obtaining consent (investigator or designee), as well as by

Safety Variables
Safety variables to be examined in this trial will include AEs, physical and neurological
examinations, vital signs, body weight, waist circumference, clinical laboratory tests 
(hematology, serum chemistry, and urinalysis), ECGs, 
 
 
 
Adverse events will be examined by frequency, severity, seriousness, discontinuation, 
and relationship to treatment.  Mean change from baseline and the incidence of 
potentially clinically relevant abnormal values will be calculated for vital signs, body 
weight, routine laboratory tests (including prolactin), and ECG parameters.  Mean change 
from baseline will be calculated for coagulation parameters (prothrombin time [PT], 
activated partial thromboplastin time [aPTT], and International Normalized Ratio [INR]), 
glycosylated hemoglobin (HbA1c), cortisol, adrenocorticotropic hormone (ACTH), 
thyroid-stimulating hormone (TSH), waist circumference, and BMI (derived 
programmatically from body weight and height measurements).  A central ECG service 
will be used to review all ECGs to standardize interpretations for the safety analysis.  
 
  
By-subject listings of physical and neurological examination findings will be reviewed as 
a further assessment of safety.
3.5.7.
Pharmacokinetic/Pharmacodynamic Variables
Plasma concentrations will be determined for brexpiprazole and its metabolite(s) and 
descriptive statistics will be calculated.  No formal statistical comparisons are planned.  
Additional population or pharmacokinetic or pharmacodynamic modeling may be 
performed as a separate analysis by combining data from this trial with data from all 
other trials.
3.6.
Measures to Minimize/Avoid Bias
3.6.1.
Randomization
During the trial, administration of the IMP will be double-blind.  In other words, neither 
the investigator nor the subject will have knowledge of the treatment assignment 
(ie, placebo or brexpiprazole).  Treatment assignments will be based on a 
computer-generated randomization code provided by the Otsuka Pharmaceutical

subjects.  Individual participation for subjects who complete the trial will range from 
16 to 22 weeks, consisting of a 2- to 42-day screening period, a 12-week double-blind 
treatment period, and a 30-day follow-up period. All subjects will be followed up at a 
clinic visit or via telephone contact 30 (+ 2) days after the last dose of the IMP.  
 
 
 
 
 
 
 
 
 
 
All trial visits will take place as a clinic visit at either the investigator’s site or residential 
facility, if applicable.  All attempts should be made to maintain the subjects’ normal 
routine with regard to physician appointments.  Individual circumstances that fall 
outside this general convention should be discussed with the medical monitor in order 
to determine appropriateness to proceed.  Trial assessment time points are summarized 
in Table 3.7-1.

aScreening begins when the ICF is signed.  Screening procedures must be initiated between Day −42 and Day −2.  The screening period may be extended after 
discussion with and approval by the medical monitor.  At the time of the subject’s screening visit, the caregiver will be provided a document that will 
outline all caregiver responsibilities.  The caregiver should acknowledge and agree to undertake all the tasks designated by this protocol at the time of the 
informed consent process.
bIf a subject discontinues prematurely before Week 12, every effort should be made to complete the Week 12/ET evaluations prior to administering additional 
medications for the treatment of agitation or other prohibited medications.
cAll subjects, whether they complete the trial or are withdrawn prematurely for any reason, will be followed up for a safety evaluation 30 (+ 2) days after the 
last dose of IMP during a clinic visit at either the investigator’s site or residential facility, if applicable.  If a clinic visit is not possible, the subject should be
assessed by telephone contact with the subject and a caregiver. Subjects who complete both the 12-week double-blind treatment period and the 30-day 
safety follow-up visit are eligible to enroll into Trial 331-13-211, which is a 2-month, observational, rollover trial to evaluate the safety of subjects with 
agitation associated with Alzheimer's disease who previously participated in Trial 331-12-283. For those subjects who plan to enroll into Trial 331-13-211, 
the 30-day safety follow-up visit for Trial 331-12-283 will occur as a clinic visit at either the investigator’s site or residential facility, if applicable.
eThe investigator must assess the capacity of the subject to provide informed consent during the screening period and throughout the course of the trial.  Once 
this determination is made by the investigator, the options for obtaining informed consent from and/or on behalf of the subject must be followed as 
provided in Section 3.4.1.
fThe investigator is responsible for ensuring that subjects are eligible for enrollment into the trial and for assessing subject safety throughout the trial. 
 
 
gThe neurological history and Hachinski Ischemic Scale (Rosen Modification) will be completed to assess eligibility for the trial by the same physician who 
performs the neurological examination (refer to Section 3.7.4.3.2).  The neurological history will include an MRI/CT scan as described in Section 3.7.3.7
and as scheduled in the ADDITIONAL ENTRANCE/HISTORY.

mVital signs include body weight, body temperature, systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate.  Blood pressure and heart 
rate will be measured in the supine (performed first), sitting, and standing positions. Blood pressure and heart rate measurements in the supine position 
should be taken after the subject has been lying for at least 5minutes. The sitting and standing measurements should be taken within 1 to 3 minutes of 
changing positions.  Vital sign measurements scheduled for the same visit as blood samples are to be completed before blood is drawn.
nSubjects should be fasting for a minimum of 8 hours prior to blood draws for screening laboratory assessments, if at all possible.  If fasting blood samples are 
not feasible at screening, nonfasting blood samples may be obtained initially for determining eligibility for the trial.  A fasting blood sample is required at 
baseline prior to dosing.  Clinical laboratory tests at other visits should be drawn fasting, if possible, but must be drawn after a minimum 8-hour fast at 
Week 12/ET.  Vital sign measurements and ECG assessments should be completed before any blood samples are collected.  See Table 3.4.3-1 for exclusion
criteria based on screening laboratory tests.
oIf a fasting blood sample was obtained at the screening visit and less than 14 days have elapsed since the screening visit, clinical laboratory tests 
(hematology, serum chemistry, and urinalysis) do not need to be repeated at the baseline visit.
pUrinalysis is not required at Week 4 or Week 8.
qAll positive urine pregnancy test results must be confirmed by a serum test.  Subjects with a positive serum pregnancy test result at screening must not be 
enrolled, and subjects with a positive serum pregnancy test result during the trial must discontinue treatment and be withdrawn from the trial.  Pregnancy 
tests can be performed at any point during the trial if pregnancy is suspected.
rStandard 12-lead ECGs will be performed after the subject has been supine and at rest for 5 minutes prior to the ECG.  The ECGs will be evaluated at the 
investigational site to determine the subject’s eligibility and to monitor safety.  Any screening ECG with abnormal result(s) considered to be clinically 
significant should be repeated (with 3 consecutive ECG recordings) to confirm the finding(s) before excluding the subject from the trial.  A central ECG 
service will review all ECGs to standardize interpretations for the safety analysis.  Any ECGs scheduled for the same visit as blood samples are to be 
completed before blood is drawn.
sA urine drug screen and a blood alcohol test are required at screening, but either or both can be conducted at any time during the trial at the discretion of the 
investigator.
tEligibility for randomization is based on the screening urine drug screen results.  Subjects whose urine drug screen is positive for cocaine, marijuana, or other 
illicit drugs at screening are not eligible for participation in the trial.  Subjects with a positive blood alcohol test or a positive urine drug screen due to use of 
prescription or OTC medications or products may be retested (the evaluation may be repeated within the screening period) or rescreened once for 
participation in the trial with consent of the medical monitor.

wPharmacokinetic samples will be obtained at baseline and at any time during the Week 8 and Week 12/ET visits.  If blood samples for clinical laboratory 
tests are not collected at the baseline visit, pharmacokinetic samples do not need to be obtained at baseline.  Every possible effort should be made to collect 
samples at the same time at each visit.  The subject should be advised to take the IMP at approximately the same time each day throughout the trial, but 
most importantly, prior to each pharmacokinetic sampling.  The date and time of the last 2 doses prior to each pharmacokinetic blood draw will be recorded 
on the electronic case report form (eCRF).  Vital sign and ECG assessments should be completed before any blood samples are collected.

Section 4.1).  During the first 4 weeks of the randomized phase (baseline to Week 4 visit), benzodiazepines are allowed but limited to 4 days/week with a 
maximum dose of 2 mg/day of lorazepam (or equivalent) or less depending on dose-limiting side effects.  Benzodiazepines must not be administered within 
12 hours prior to the efficacy and safety scales. After the Week 4 visit, benzodiazepines are prohibited.

aaSubjects will start taking the IMP from the new blister card the day after the clinic visit.
bbThe subject’s identified caregiver will be contacted by telephone at Weeks 3, 5, and 7 to assess compliance with IMP, confirm any changes to concomitant 
medications, and assure the subject’s well-being.
ccIf a previous MRI or CT scan of the brain performed after the onset of the symptoms of dementia is not available, then an MRI/CT scan should be 
performed during screening.  In addition, a repeat MRI/CT scan of the brain may be requested to be performed 
in order to confirm 
eligibility.

3.7.1.1.
Screening
The screening period begins after written informed consent has been obtained.  Subjects 
will participate in screening activities for 2 days to 42 days.  The screening period may be 
extended after discussion with and approval by the medical monitor.  After the ICF has 
been signed, the site will obtain a Subject identification/identifier (ID) by accessing the 
IVRS or IWRS.  Completion of screening activities may require more than 1 visit; 
however, only the initial visit will be registered in the IVRS or IWRS.
 
Screening evaluations will include the following:

At the time of the subject’s screening visit, the caregiver will be provided a document 
that will outline all caregiver responsibilities and their role in this trial.  The caregiver 
should acknowledge and agree to undertake all the tasks designated by this protocol 
at the time of the informed consent process.

Trial personnel will call the IVRS or access the IWRS to register the visit (initial 
screening visit only).

The investigator must assess the capacity of the subject to provide informed consent 
during the screening period.  Once this determination is made by the investigator, the 
options for obtaining informed consent from and/or on behalf of the subject must be 
followed as provided in Section 3.4.1.

An assessment of all inclusion and exclusion criteria will be made to determine the 
subject’s eligibility for the trial.

Demographic data will be recorded.

A general clinical evaluation will be performed, including concurrent medical 
conditions, medical history over the past 2 years, and medical history beyond 2 years 
that is considered to be clinically relevant per the investigator’s judgment.

Psychiatric and neurological history will be recorded.

If a previous MRI or CT scan of the brain performed after the onset of the symptoms 
of dementia is not available, then an MRI/CT scan of the brain should be performed
during screening.  In addition, a repeat MRI/CT scan of the brain may be requested to 
be performed 
in order to confirm eligibility.  Medications taken 
within 30 days of screening (signing of ICF/assent) will be recorded.

Washout from prohibited concomitant medications will begin, if applicable (see 
Section 4.1).

3.7.2.
Efficacy Assessments
It is required that adequately trained and experienced clinicians administer the CMAI, 
NPI-NH, NPI/NPI-NH, CGI-S, 
 and 
  In addition, the raters must be 
certified for this trial to administer the CMAI, NPI-NH, and NPI/NPI-NH.  Notations in 
the subject’s trial records should substantiate the ratings.  Training, certification, and 
materials for rating will be provided by a rater training group.
A caregiver must be identified during the screening period for participation in the 
interview for the CMAI, NPI-NH, NPI/NPI-NH, and other applicable trial assessments. 
In addition to providing responses to trial questionnaires, the identified caregiver will be 
interviewed by the trial personnel regarding the subject’s general medical condition, 
behavioral symptoms, and activities of daily living.  If the subject is in an 
institutionalized setting, the identified caregiver will gather information from several 
informants, including staff from the day, afternoon, and night shifts, as well as from 
reliable family members or friends, in order to provide an accurate and comprehensive 
overview of the subject’s behavioral symptoms and condition.  If the subject is in a 
non-institutionalized setting, the identified caregiver can gather information from the 
caretaker (if different than the identified caregiver) or from other informants who are in a 
position to observe the subject and provide information regarding behavioral symptoms 
and activities of daily living.  Details on the caregiver requirements can be found in 
Section 3.3.1.

agitation.11  As initially described by Cohen-Mansfield11 and outlined in the Instruction 
Manual for the CMAI,26 these distinct agitation syndromes include:  aggressive behavior, 
physically nonaggressive behavior, and verbally agitated behavior.  A sample of the 
CMAI is provided in Appendix 6.
3.7.2.2.
Clinical Global Impression-Severity of Illness Scale (CGI-S)
The severity of agitation for each subject will be rated using the CGI-S.27  To perform 
this assessment, the investigator (or designee) will answer the following question: 
“Considering your total clinical experience with this particular population, how mentally 
ill (as related to agitation) is the subject at this time?”  Response choices are 0 = not 
assessed; 1 = normal, not at all ill; 2 = borderline mentally ill; 3 = mildly ill; 
4 = moderately ill; 5 = markedly ill; 6 = severely ill; and 7 = among the most extremely 
ill subjects.  A sample of the CGI-S is provided in Appendix 7.

Neuropsychiatric Inventory-Nursing Home (NPI-NH)
The NPI-NH questionnaire is used to interview the identified caregiver about the 
institutionalized subject’s possible neuropsychiatric symptoms (ie, delusions, 
hallucinations, agitation/aggression, depression/dysphoria, anxiety, elation/euphoria, 
apathy/indifference, disinhibition, irritability, aberrant motor behavior, nighttime 
behaviors, and appetite/eating behaviors).  The NPI-NH gives an insight into the 
frequency (on a scale of 1 to 4), severity (on a scale of 1 to 3), and occupational 
disruption (on a scale of 0 to 5) of each of the 12 separate behavioral domains.28,29
Therefore, for each behavioral domain, there are 4 scores:  frequency, severity, total 
(frequency x severity), and occupational disruptiveness.  A total NPI-NH score can be 
calculated by adding the first 10 domain total scores (frequency x severity scores) 
together. All 12 domain total scores can be summed in special circumstances where the 
neurovegetative symptoms are of particular importance.29  Administering the 
questionnaire generally takes about 15 minutes.  The psychometric properties and factor 
structure of the NPI-NH have been shown to have internal consistency, reliability, 
convergent validity, and discriminant validity.30
A sample of the NPI-NH is provided in Appendix 8.
3.7.2.6.
Neuropsychiatric Assessment for Non-institutionalized Patients
Based on the NPI/NPI-NH (NPI/NPI-NH)
The NPI/NPI-NH is a structured caregiver interview designed to obtain information on 
the presence of psychopathology in non-institutionalized subjects with brain disorders, 
including Alzheimer’s disease and other dementias.31  The NPI/NPI-NH differs from the 
NPI-NH in that questions referring to “Occupational Disruptiveness” from the NPI-NH 
have been replaced with questions referring to “Distress” from the Neuropsychiatric 
Inventory (NPI). Item domains are identical between the NPI/NPI-NH and NPI-NH.  
Ten behavioral and two neurovegetative symptom domains comprise the NPI/NPI-NH
(ie, delusions, hallucinations, agitation/aggression, depression/dysphoria, anxiety, 
elation/euphoria, apathy/indifference, disinhibition, irritability, aberrant motor behavior, 
nighttime behavior disorders, and appetite/eating disorders).  The identified caregivers 
are instructed to indicate the frequency (on a scale of 1 to 4), severity (on a scale of 1 to 
3), and distress (on a scale of 0 to 5) of each of the 12 separate behavioral domains.  
Therefore, for each behavioral domain, there are 4 scores:  frequency, severity, total 
(frequency x severity), and distress.  A total NPI/NPI-NH score is calculated by adding 
the first 10 domain total scores (frequency x severity scores) together.  All 12 domain

National Institute of Neurological and Communicative 
Disorders and Stroke and the Alzheimer’s Disease and Related 
Disorders Association (NINCDS-ADRDA)
The NINCDS-ADRDA, which has shown good reliability and validity, provides criteria 
for the possible and probable diagnosis of Alzheimer’s disease.37  These criteria require 
that cognitive impairment and a suspected dementia syndrome be confirmed by
neuropsychological testing for a clinical diagnosis of Alzheimer’s disease.  The 
NINCDS-ADRDA criteria specify 8 cognitive domains that may be impaired in 
Alzheimer’s disease: memory, language, perceptual skills, attention, constructive 
abilities, orientation, problem solving, and functional abilities.
A sample of the NINCDS-ADRDA is provided in Appendix 14.

Hachinski Ischemic Scale (Rosen Modification)
The Rosen-modified Hachinski Ischemic Scale assesses whether a subject’s dementia is 
likely due to vascular causes by the response to 8 questions:  abrupt onset, stepwise 
deterioration, somatic complaints, emotional incontinence, history of hypertension, 
history of stroke, focal neurologic signs, and focal neurologic symptoms.38 The 
Rosen-modified Hachinski Ischemic Scale will be completed to assess eligibility for the 
trial by the same physician who performs the neurological examination (see 
Section 3.7.4.3.2).
A sample of the Hachinski Ischemic Scale (Rosen Modification) is provided in

Magnetic Resonance Imaging/Computed Tomography Scan of 
the Brain
If an MRI/CT scan of the brain performed after the onset of the symptoms of dementia is 
not available, then an MRI/CT scan should be performed during screening.  In addition, a 
repeat MRI/CT scan of the brain may be requested to be performed 
in 
order to confirm eligibility.

Clinical Laboratory Assessments
A central laboratory designated by the sponsor will be used for all laboratory testing 
required during the trial.  The central laboratory should be used for all laboratory testing 
whenever possible (including unscheduled and follow-up, if needed).  In cases where an 
immediate result is required for a particular laboratory test, the sample should be divided 
and sent to both a local laboratory and the designated central laboratory.  Urine will be 
collected and blood will be drawn from each subject during screening prior to treatment 
with the IMP.  Subjects should be fasting for a minimum of 8 hours prior to the blood 
draws, if possible.  If fasting blood samples are not feasible at screening, nonfasting 
blood samples may be obtained initially for determining eligibility for the trial.  A fasting 
blood sample is required at baseline prior to dosing. If a fasting blood sample was 
obtained at the screening visit and less than 14 days have elapsed since the screening 
visit, clinical laboratory tests (hematology, serum chemistry, and urinalysis) do not need 
to be repeated at the baseline visit.  The results of these tests must be reviewed by the 
investigator prior to initiation of the administration of the IMP.  Additional urine and 
blood samples may be collected for further evaluation of safety as warranted by the 
investigator’s judgment.  Reports from the central laboratory should be filed with the 
source documents for each subject.  The central laboratory will provide laboratory results 
to the sponsor electronically.

Any value outside the normal range will be flagged for the attention of the investigator 
who must indicate whether or not a flagged value is of clinical significance.  If one or 
more values are questionable, the test(s) may be repeated.  If the result of any test (or 
repeat test, if done) is indicated as clinically significant in the samples taken during the 
screening period, the subject will NOT be enrolled into the trial without the permission of 
the medical monitor.  In addition, follow-up unscheduled laboratory tests should be 
performed if clinically significant abnormalities are observed.  Unscheduled laboratory 
tests may be repeated at any time at the discretion of the investigator for appropriate 
medical care.  Refer to Appendix 3 for criteria for identifying values of potential clinical 
relevance.
The following laboratory test results at screening are exclusionary:

Platelets 75,000/mm3

Hemoglobin ≤ 9 g/dL


A complete physical examination will be performed at screening and will consist of 
measurement of height and waist circumference and a review of the following body 
systems:  head, eyes, ears, nose, and throat (HEENT); thorax; abdomen; urogenital; 
extremities; neurological (see Section 3.7.4.3.2); and skin and mucosa.  At screening, 
height will be measured with a stadiometer, measuring stick or tape.  Repeat 
measurement of height is not required at the physical examinations scheduled for the 
Week 12/ET visit.  Waist circumference will be measured at each physical examination

(screening and Week 12/ET), using the provided measuring tape.  The following 
procedures will aid in the standardization of these measurements:

The subject should be minimally clothed (ie, lightweight clothing; no heavy 
overgarments).

Waist circumference should be recorded before a subject’s meal and at approximately 
the same time at each visit.

Measurement will be accomplished by locating the upper hip bone and the top of the 
right iliac crest and placing a weighted measuring tape in a horizontal plane around 
the abdomen at the level of the crest.  Before reading the tape measure, the assessor 
should assure that the tape is snug, but does not compress the skin, and is parallel to 
the floor.  The measurement is to be made at the end of a normal exhalation.39
The investigator (or designee) is responsible for performing the physical examination.  If 
the appointed designee is to perform the physical examination, he or she must be 
permitted by local regulations and his/her name must be included on the FDA Form 
1572.  Whenever possible, the same individual should perform all physical examinations.  
Any condition present at the post-treatment physical examination that was not present at 
the baseline examination should be documented as an AE and followed to a satisfactory 
conclusion.
3.7.4.3.2.
Neurological Examination
A detailed neurological examination will be performed by a physician at screening, 
Week 12/ET, and as needed during the trial for new onset neurological symptoms. The 
neurological examination will consist of an evaluation of the subject’s mental status, 
cranial nerves, motor system (eg, motor strength, muscle tone, reflexes), cerebellar 
system (eg, coordination), gait and station, and sensory system.
The physician is responsible for performing the neurological examination and must be 
included on the Form FDA 1572.  Whenever possible, the same physician should perform 
all neurological examinations.  Any condition present at the post-treatment neurological 
examination that was not present at the baseline examination and that is determined to be 
an AE should be documented as an AE and followed to a satisfactory conclusion.  If new 
potentially clinically relevant neurological signs or symptoms are identified, referral to a 
neurologist is recommended.

Vital Signs
Vital sign measurements will include body weight, body temperature, systolic blood 
pressure (SBP), diastolic blood pressure (DBP), and heart rate.  The following guidelines 
will aid in the standardization of body weight measurements:

The same scale should be used to weigh a given subject each time, if possible.

Scales should be calibrated and reliable; scales should be at zero just prior to each 
subject’s weigh-in session.

A subject should void prior to being weighed and be minimally clothed (ie, no shoes 
or heavy overgarments).

Weight should be recorded before a subject’s meal and at approximately the same 
time at each visit.
Blood pressure and heart rate measurements will be made in the supine, sitting, and 
standing positions.  The supine measurements will be performed first, followed by sitting, 
and finally standing.  Blood pressure and heart rate measurements in the supine position 
should be taken after the subject has been lying for at least 5 minutes. The sitting and 
standing measurements should be taken within 1 to 3 minutes of changing positions.  
Vital signs scheduled at the same visit as blood samples are to be completed before blood 
is drawn.
Subjects with uncontrolled hypertension (screening DBP > 95 mmHg in any position) or 
symptomatic hypotension are excluded from the trial as are subjects with orthostatic 
hypotension, which is defined as a decrease of 30 mmHg in SBP and/or a decrease of 
20 mmHg in DBP within 3 minutes of standing compared to the previous supine blood 
pressure or development of symptoms (see Table 3.7-1).  In addition, subjects should be 
excluded if they have any other vital sign measurement at screening that, in the 
investigator’s judgment, is medically significant in that it would impact the safety of the 
subject or the interpretation of the trial results.  However, any abnormal screening vital 
sign result(s) considered to be clinically significant should be repeated to confirm the 
finding(s) before excluding the subject from the trial.  Refer to Appendix 4 for a list of 
potentially clinically significant vital signs.
3.7.4.4.
ECG Assessments
Standard 12-lead ECGs will be recorded at screening and at the visits specified in 
Table 3.7-1.  Any ECGs scheduled for the same visit as blood samples are to be 
completed before blood is drawn.  ECG recordings will be obtained after the subject has 
been supine and at rest for at least 5 minutes.  Additional 12-lead ECGs may be obtained 
at the investigator’s discretion and should always be obtained if the subject is terminated

early.  The ECG results will be evaluated at the investigational site to determine the 
subject’s eligibility and to monitor safety during the trial.  The principal investigator (or 
qualified designee) will review, sign, and date each ECG reading, noting whether or not 
any abnormal results are of clinical significance.  The ECG will be repeated if any results 
are considered to be clinically significant.  A central ECG service will be used for reading 
all ECGs in order to standardize interpretations for the safety analysis.
If, according to the investigator's judgment, any abnormal ECG finding is deemed 
medically significant (impacting the safety of the subject and/or the interpretation of the 
trial results) or meets an exclusion criterion (see Table 3.4.3-1), the subject should be 
excluded from the trial. Abnormal results for ECGs should be repeated once at screening 
with 3 consecutive ECG recordings to ensure reproducibility of the abnormality before 
excluding a subject based on the criteria noted above. Each ECG recording should be 
taken approximately 5 minutes apart (the ECG result reported will be evaluated at each 
time point). The central ECG service will provide the corrections for the 3 ECGs 
performed.  Based on the QT interval as corrected by Fridericia’s formula (QTcF) 
reported by the central service, a subject will be excluded if the corrections are 
≥450 msec in men and ≥ 470 msec in women for 2 of the 3 time points of the ECGs 
done, unless due to ventricular pacing. If only 1 ECG time point has a QTcF of 
≥450 msec in men and ≥ 470 msec in women, and this is not reproduced at either of the 
other 2 time points, the subject can be included in the trial.  
Refer to Appendix 5 for a list of potentially clinically relevant ECG abnormalities to 
guide investigators for the assessment of potential ECG abnormalities for clinical 
significance postrandomization.  Exclusion criteria for screening do not apply as 
mandatory discontinuation criteria for subjects who are already randomized.  Please 
consult the medical monitor in case of questions.

Mini-Mental State Examination (MMSE)
The MMSE43 is a brief practical test for assessing cognitive dysfunction. The test 
consists of 5 sections (orientation, registration, attention and calculation, recall, and 
language) and has a total possible score of 30.  The MMSE is used for screening subjects 
(refer to Table 3.4.3-1) and is also to be completed at Week 12/ET.  A sample of the 
MMSE is provided in Appendix 20.

Blood Collection Times
Pharmacokinetic samples will be collected at baseline and at any time during Week 8 and 
Week 12/ET.  If blood samples for clinical laboratory tests are not collected at the 
baseline visit, pharmacokinetic samples do not need to be obtained at baseline.  The 
samples will be collected at the same time as clinical laboratory sample collection for the 
designated trial visits, if applicable.  Every possible effort should be made to collect 
pharmacokinetic samples at the same time at each visit.  Furthermore, the subject should 
be advised to take the IMP at approximately the same time each day throughout the trial, 
but most importantly, prior to each pharmacokinetic sampling.  The date and time of the 
last 2 doses of IMP prior to each sample draw, and the date and time of the actual blood 
draw will be recorded on the eCRF.

Stopping Rules, Withdrawal Criteria, and Procedures
3.8.1.
Entire Trial or Treatment Arm(s)
If the sponsor terminates or suspends the trial for safety or unanticipated other reasons, 
prompt notification will be given to investigators, IRBs/IECs, and regulatory authorities 
in accordance with regulatory requirements.
3.8.2.
Individual Site
A particular center may be terminated from the trial at the discretion of the investigator, 
sponsor, or IRB/IEC, eg, for non-enrollment of subjects or noncompliance with the 
protocol.  The investigator will notify the sponsor promptly if the trial is terminated by 
the investigator or the IRB/IEC at the site.
3.8.3.
Individual Subject
If a subject discontinues the trial prematurely, the reason must be fully evaluated and 
recorded appropriately in source documents and the eCRF.  If the subject is being 
withdrawn because of an AE, the AE should be indicated as the reason for withdrawal.
All subjects have the right to withdraw at any time during treatment without prejudice.  
The investigator can discontinue a subject’s participation in the trial at any time if 
medically necessary.  In addition, subjects meeting any of the following criteria must be 
withdrawn from the trial:
1) Occurrence of any AE, intercurrent illness, or abnormality in a laboratory assessment 
that, in the opinion of the investigator, warrants the subject’s permanent withdrawal 
from the trial
2) Treatment with a prohibited concomitant medication other than the use of appropriate 
medications for the treatment of AEs under direction of the investigator
3) Subject noncompliance, defined as refusal or inability to adhere to the trial schedule 
or procedures (see Section 3.12, Subject Compliance)
4) At the request of the subject, caregiver, legally acceptable representative, investigator, 
sponsor, or regulatory authority
5) Subject becomes pregnant
6) Subject cannot tolerate the assigned dose of brexpiprazole (or matching placebo)
7) Subject develops clinically significant agitation per investigator’s judgment that 
cannot be adequately treated with allowed medications and poses a potential safety 
risk to the subject and/or others 
8) Subject is lost to follow-up

9) Subject transfers from an institutionalized setting to a non-institutionalized setting, or 
vice versa.  In case of a brief hospitalization, determination of subject eligibility to 
stay in the trial must be made based on subject safety by the investigator and medical 
monitor.  
 
 
The investigator will notify the sponsor promptly when a subject is withdrawn.  Subjects 
withdrawn prior to Week 12 must complete the Week 12/ET evaluations at the time of 
withdrawal.  In addition, all subjects who withdraw prematurely from the trial will be 
assessed 30 (+2) days after the last dose of the IMP for evaluation of safety.  This 
assessment can be accomplished at a clinic visit at either the investigator’s site or 
residential facility, if applicable.  If a clinic visit is not possible, the subject should be 
assessed by telephone contact with the subject and a caregiver.
 
 
  Three attempts will be 
made to contact the subject's caregiver by telephone; in the event the site is unable to 
reach the subject's caregiver by telephone, the site will attempt to contact the subject's 
caregiver via certified mail or an alternative similar method where appropriate.
Any subject who withdraws prematurely from the trial will not be eligible to roll-over 
into Trial 331-13-211.  
Meeting a screening exclusion criterion postrandomization does not require an automatic 
discontinuation of the subject.  The investigator should assess the change for clinical 
significance, determine if an AE should be reported, and make a determination of subject 
continuation based on subject safety.  The investigator could consult with the medical 
monitor to determine subject continuation in the trial.

3.9.
Screen Failures
A screen failure is a subject from whom a signed ICF is obtained, but who has not started 
on treatment.  For this trial, treatment begins with the first dose of the IMP.  If a subject 
fails to qualify for the trial during the 42-day screening period for a reason other than a 
positive screen for cocaine, marijuana, or other illicit drugs, the subject is permitted to be 
rescreened at a later date.  A subject may be rescreened more than once after discussion 
with and approval by the medical monitor.  The medical monitor must be contacted 
before rescreening any subjects who initially failed screening due to a positive blood 
alcohol test or positive drug screens resulting from use of prescription or OTC 
medications or products.  In the event that the subject is rescreened for trial participation, 
a new ICF must be signed, a new screening number assigned, and all screening 
procedures repeated.
3.10.
Definition of Completed Subjects
The treatment period is defined as the time period during which subjects are evaluated for 
primary or secondary objectives of the trial irrespective of whether or not the subject was 
administered 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 purposes of this trial, 
subjects who complete the Week 12 visit will be defined as trial completers.
3.11.
Definition of Subjects Lost to Follow-up
Subjects who cannot be contacted on or before the Week 12 visit during the treatment 
period and who do not have a known reason for discontinuation (eg, withdrew consent or 
AE) will be classified as “lost to follow-up.” If an institutionalized subject leaves the 
residential facility in which he/she was residing before completion of the trial, the site 
will make 3 attempts to contact the subject by telephone; 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.  A similar procedure will be 
followed for non-institutionalized subjects who are lost to follow-up.
3.12.
Subject Compliance
Responsible trial personnel will dispense the IMP (ie, brexpiprazole or matching placebo)
according to the visits outlined in the Schedule of Assessments (Table 3.7-1).  
Accountability and compliance verification should be documented in the subject’s trial 
records.

For non-institutionalized subjects, the caretaker or caregiver may administer IMP to the 
subject, as long as the subject is compliant with IMP dosing requirements.
For institutionalized subjects, the caregiver will be responsible for administering IMP to 
the subject.  It may be possible that there is more than one caregiver for a subject.  The 
caregiver(s) should be appropriately instructed to ensure that the subject is compliant 
with IMP dosing requirements.
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 medication criteria), the investigator or designee will contact the sponsor’s 
designee (medical monitor) at the earliest possible time by telephone.  The investigator 
and sponsor’s designee (medical monitor) 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 and the sponsor and reviewed by the site monitor.
4. Restrictions
4.1.
Prohibited Medications

specific oral benzodiazepines is permitted during screening and during the first 4 weeks of the 
randomization phase (baseline to Week 4 visit) to treat agitation and/or insomnia (see Table 4.1-3).
bBenzodiazepines must not be administered within 12 hours prior to scheduled efficacy and safety 
scales, including EPS scales.  Investigators are encouraged to delay scale administration until 12 
hours have elapsed, if at all possible.  However, if delaying administration of efficacy and safety

aBenzodiazepines must not be administered within 12 hours prior to scheduled efficacy and safety 
scales, including EPS scales. Investigators are encouraged to delay scale administration until 
12 hours have elapsed, if at all possible.  However, if delaying administration of efficacy and safety 
scales is not feasible, the scales should still be administered and the use of benzodiazepine 
documented, including a notation of the drug name, dose, and time of administration on the eCRF.
bIn countries where no short-acting benzodiazepines are commercially available, use of oral diazepam 
(maximum allowable daily dose of 10 mg/day) or oral clonazepam (maximum allowable daily dose of 
1 mg/day) may be acceptable if prior authorization is obtained from the medical monitor.

Other Restrictions
The following restrictions apply:

Subjects should not undergo any elective medical procedure without prior 
consultation with the investigator.  An elective procedure (minor surgery, dental 
surgery, orthopedic surgery, etc.) that might require hospitalization or general 
anesthesia should be deferred until after the trial whenever clinically appropriate.

Consumption of grapefruit, grapefruit products, Seville oranges, or Seville orange 
products within 72 hours prior to the first dose of IMP and during the trial is 
prohibited.

Subjects should refrain from drinking alcoholic beverages or using illicit drugs during 
participation in the trial.

5. Reporting of Adverse Events
5.1.
Definitions
An AE is defined as any untoward medical occurrence associated with the use of a drug 
in humans, whether or not considered drug related.
A suspected adverse reaction means any AE for which there is a reasonable possibility 
that the drug caused the AE.  For the purpose of IND safety reporting, “reasonable 
possibility” means there is evidence to suggest a causal relationship between the drug and 
the AE. Suspected adverse reaction implies a lesser degree of certainty about causality.
An SAE includes any event that results in any of the following outcomes:
1) Death
2) Life-threatening, ie, the subject was, in the opinion of the investigator, 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.
3) Persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life functions.
4) Requires in-patient hospitalization or prolongs hospitalization (NOTE:  A 
prescheduled hospitalization is not considered an SAE.)
5) Congenital anomaly/birth defect
6) 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.
Non-serious adverse events are AEs that do not meet the criteria for an SAE.

If a subject is experiencing an extrapyramidal symptom, the specific extrapyramidal 
symptom must be indicated on the AE page of the eCRF. Examples of AEs that are 
considered extrapyramidal symptoms include, but are not limited to: generalized rigidity, 
dyskinesia, hyperkinesia, bradykinesia, akinesia, dystonia, hypertonia, akathisia, tremor, 
flexed posture, involuntary muscle contractions, athetosis, and chorea.  If a subject is 
experiencing two or more of these symptoms, whether or not treatment with an 
anticholinergic is required, this is considered as extrapyramidal syndrome and must be 
entered as “extrapyramidal syndrome” on the AE page of the eCRF instead of the 
individual symptoms.
Immediately Reportable Event (IRE)

Any SAE

Any AE that necessitates discontinuation of the IMP

Potential Hy’s law cases (any increase of AST or ALT ≥ 3 times the ULN with an 
increase in total bilirubin ≥ 2 times the ULN)
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 INC Research.  
Pregnancy will only be documented on the AE eCRF if there is an abnormality or 
complication.
Clinical Laboratory Changes
It is the investigator’s responsibility to review the results of all laboratory tests as they 
become available.  This review will be documented by the investigator’s dated signature 
on the laboratory report.  For each abnormal laboratory test result, the investigator needs 
to ascertain if this is an abnormal (ie, clinically significant) 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 may repeat the laboratory 
test or request additional tests to verify the results of the original laboratory tests).  If this 
laboratory value is determined by the investigator to be an abnormal change from 
baseline for that subject, this is considered an AE.

Severity
All AEs will be graded on a 3-point scale and reported as indicated on the eCRF.  The 
intensity of an adverse experience 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
The causal relationship of an AE to the use of the IMP will be assessed as follows:
Related: 
There is a reasonable possibility of a causal relationship
Possibly related: There is a reasonable causal relationship between the IMP and the 
AE.  Dechallenge is lacking or unclear
Unlikely related: There is a temporal relationship to the IMP administration, but 
there is not a reasonable causal relationship between the IMP and 
the AE
Not related: 
There is no temporal or reasonable relationship to the IMP 
administration
5.2.
Eliciting and Reporting Adverse Events
The investigator will periodically assess subjects for the occurrence of AEs.  To avoid 
bias in eliciting AEs, subjects should be asked the following nonleading question: "How 
have you felt since your last visit?"  All AEs (serious and nonserious) reported by the 
subject must be recorded on the source documents and eCRFs provided by the sponsor or 
designee.
In addition, INC Research (refer to Appendix 2) must be notified immediately by 
telephone or fax of any immediately reportable events according to the procedure 
outlined below in Section 5.3.  Special attention should be paid to recording 
hospitalization and concomitant medications.
5.3.
Immediately Reportable Events (IRE)
The investigator must immediately report within 24 hours after either the investigator or 
site personnel become aware of any SAE or potential Hy’s law cases (refer to 
Section 5.4) by telephone or by fax to the sponsor or designee, as outlined in Appendix 2.  
An IRE form must be completed and sent by fax or overnight courier to the sponsor.  
(Note:  the IRE form is NOT the AE eCRF.)

Nonserious events that require discontinuation of the IMP (including laboratory 
abnormalities) should be reported to the sponsor within 3 working days.  The IRE form 
must be completed and sent by fax or overnight courier to the sponsor.
Subjects experiencing SAEs should be followed clinically until their health has returned 
to baseline status or until all parameters have returned to normal or have otherwise been 
explained.  It is expected that the investigator will provide or arrange appropriate 
supportive care for the subject.
5.4.
Potential Hy’s Law Cases
For subjects that experience an elevation in AST or ALT that is ≥ 3 times the ULN, a 
total bilirubin level should also be evaluated.  If the total bilirubin is ≥ 2 times the ULN, 
confirmatory repeat laboratory samples should be drawn within 48 to 72 hours of the 
initial draw.  If these values are confirmed, trial personnel will complete an IRE form 
with all values listed and also report the event as an AE on the eCRF.  Please note: if the 
subject was enrolled into the trial with non-exclusionary elevated transaminase levels at 
baseline, please discuss any potential drug-induced liver injury events with the medical 
monitor.
5.5.
Pregnancy
Women of childbearing potential and men who are sexually active must use an effective 
method of birth control during the course of the trial and for at least 30 days after the last 
dose in a manner such that risk of failure is minimized.  Unless the subject is sterile (ie, 
women who have had an oophorectomy and/or hysterectomy or have been 
postmenopausal for at least 12 consecutive months; or men who have had orchiectomy) 
or remains abstinent, two of the following precautions must be used:  vasectomy, tubal 
ligation, vaginal diaphragm, intrauterine device, birth control pills, birth control depot 
injection, birth control implant, condom or sponge with spermicide, or any other method 
approved by the medical monitor.  Any single method of birth control, including 
vasectomy and tubal ligation, may fail, leading to pregnancy.
Before enrolling women of childbearing potential in this clinical trial, investigators must 
review guidelines about their participation in this trial.  The topics should generally 
include:

General information

Informed consent

Pregnancy prevention information

Guidelines for the follow-up of a reported pregnancy
Prior to trial enrollment, women of childbearing potential must be advised of the 
importance of avoiding pregnancy during trial participation and the potential risk factors 
for an unintentional pregnancy.  The subject must sign an ICF stating that the above-
mentioned risk factors and the consequences were discussed with her.
During the trial, all women of childbearing potential should be instructed to contact the 
investigator immediately if they suspect they might be pregnant (eg, missed or late 
menstrual cycle).
If a subject or investigator suspects that the subject may be pregnant prior to IMP 
administration, the IMP administration must be withheld until the results of serum 
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 the IMP, the IMP must be withheld immediately (if reasonable, taking into 
consideration any potential withdrawal risks) until the result of the pregnancy 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 withdrawn from 
the trial.  Exceptions to trial discontinuation may be considered for life-threatening 
conditions only after consultation as indicated in Appendix 2.
The investigator must immediately notify the sponsor (or sponsor’s designee) of any 
pregnancy associated with IMP exposure, including at least 30 days after the last dose for 
female subjects and the female partner of a male subject and record the event on the IRE 
form and forward it to the sponsor (or sponsor’s designee).
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 must report to the sponsor (or sponsor’s designee), 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.

Procedure for Breaking the Blind
The investigator is encouraged to contact the sponsor/Clinical Research Organization 
(CRO) medical advisor to discuss their rationale for unblinding.  However, to prevent 
delays to the investigator or medical personnel responding to a potentially emergent 
situation, unblinding of the IMP will not be dependent upon the investigator receiving 
approval from the sponsor/CRO medical monitor (ie, the investigator will be able to 
obtain the code break information independent of the sponsor/CRO medical advisor).  
The investigator must contact the sponsor/CRO medical advisor by telephone with an 
explanation of the need for opening the treatment assignment code within 24 hours of 
opening the code. If the blind is broken, the clinical safety and pharmacovigilance 
department listed in Appendix 2 will be notified immediately.  Documentation of 
breaking the blind should be recorded in the subject’s medical record with the date and 
time the blind was broken and the names of the personnel involved.  Once the blind is 
broken for a given subject, that subject may not reinitiate treatment with the IMP.
5.7.
Follow-up of Adverse Events
5.7.1.
Follow-up of Nonserious Adverse Events
Nonserious AEs that are identified on the last scheduled contact must be recorded on the 
AE eCRF with the current status noted.  All nonserious events that are ongoing at this 
time will be recorded as ongoing on the eCRF.
5.7.2.
Follow-up of Post-Trial Serious Adverse Events
All SAEs that are identified on the last scheduled contact must be recorded on the AE 
eCRF page and reported to the sponsor according to the reporting procedures outlined in 
Section 5.3.  This may include unresolved previously reported SAEs or new SAEs.  The 
investigator will follow SAEs until the events are resolved or the subject is lost to 
follow-up.  Resolution means the subject has returned to the baseline state of health, or 
the investigator does not expect any further improvement or worsening of the subject’s 
condition.  The investigator will continue to report any significant follow-up information 
to OPDC up to the point the event has been resolved.
This trial requires that subjects be actively monitored for SAEs up to 30 days after 
discharge from the trial.

Follow-up and Reporting of Serious Adverse Events Occurring 
after Last Scheduled Contact
Any new SAEs reported by the subject to the investigator that occur after the last 
scheduled contact and are determined by the investigator to be reasonably associated with 
the use of the IMP, should be reported to OPDC.  This may include SAEs that are 
captured on follow-up telephone contact or at any other time point after the defined trial 
period (ie, up to last scheduled contact).  The investigator should follow related SAEs 
identified after the last scheduled contact until the events are resolved or the subject is 
lost to follow-up.  The investigator should continue to report any significant follow-up 
information to OPDC up to the point the event has been resolved.

6. Pharmacokinetic Analysis
Pharmacokinetic samples will be analyzed for brexpiprazole (OPC-34712) and its 
metabolite(s) and descriptive statistics will be calculated.  No formal statistical 
comparisons are planned.  A separate population or pharmacokinetic/pharmacodynamic 
modeling may be performed using the data from this trial and other trials.
7. Statistical Analysis
7.1.
Sample Size
The sample size was calculated based on the treatment effect of 6.5 points with a standard 
deviation (SD) of 16.5 in the change from baseline (Day 0 visit) to the end of the 
double-blind treatment period (Week 12 visit) in the CMAI total score, to achieve 85% 
power at a 2-sided alpha level of 0.05.  This results in 117 subjects in each of the groups 
(ie, brexpiprazole 1 mg/day, brexpiprazole 2 mg/day, and placebo).  After allowance of 
10% non-evaluable subjects, the total number of subjects to be randomized is 132 per 
treatment arm.  The sample size was estimated based on a 1:1:1 randomization ratio 
(brexpiprazole 1 mg/day, brexpiprazole 2 mg/day, placebo).

Datasets for Analysis
The following samples are defined for this trial:

Randomized: consists of all subjects who were randomized into this trial

Safety: consists of all subjects who were administered at least one dose of IMP

Efficacy: The intent-to-treat (ITT) population consists of all subjects in the 
randomized sample who took at least 1 dose of IMP (brexpiprazole 1 mg/day, 
brexpiprazole 2 mg/day, or placebo) and have a baseline and at least one postbaseline 
evaluation for the CMAI total score.
In general, baseline of an efficacy endpoint is defined as the last observation of the 
endpoint before the subject is randomized.
The core dataset for all efficacy analyses is based on the ITT population, which is defined 
in the efficacy sample above.  As will be described below, in order to handle missing data 
and restrictions imposed by different types of analyses (eg, change from baseline 
analysis), datasets derived from the ITT population will be used for the efficacy analysis.

Efficacy Analyses
7.4.1.
Primary Efficacy Analysis
The primary endpoint will be analyzed using an MMRM model.  The primary efficacy 
outcome measure is the mean change from baseline (Day 0 visit) to the end of the 
double-blind treatment period (Week 12 visit) in the CMAI total score.  The primary 
statistical comparisons of interest are brexpiprazole 2 mg/day versus placebo and 
brexpiprazole 1 mg/day versus placebo.  The null hypotheses of these comparisons are 
that there is no difference between the brexpiprazole treatment groups and placebo in 
change from baseline to endpoint in CMAI total score.  To protect the experiment-wise 
2-sided alpha level at 0.05 when making 2 comparisons of brexpiprazole doses versus 
placebo, the statistical testing will be carried out using a hierarchical testing procedure in 
the order of 1) comparison of 2 mg/day brexpiprazole versus placebo and 2) comparison 
of 1 mg/day brexpiprazole versus placebo.  Thus, if the test yields a statistically 
significant result at 0.05 (2-sided) for the comparison of 2 mg/day brexpiprazole versus 
placebo, then the comparison of 1 mg/day brexpiprazole versus placebo will be tested at 
an alpha level of 0.05 (2-sided).
The statistical comparison will be performed by the MMRM analysis with an 
unstructured variance covariance matrix for the repeated measures in which the change 
from baseline (Day 0 visit) in CMAI total score (at Weeks 2, 4, 6, 8, 10, and 12) will be 
the dependent variable based on the OC dataset.  The model will include fixed 
class-effect terms for treatment, trial center, visit week, and an interaction term of 
treatment by visit week and include the interaction term of baseline values of CMAI total 
score by visit week as a covariate.  The primary comparison between brexpiprazole and 
the placebo arm at Week 12 will be estimated as the difference between least squares 
(LS) means from the interaction term of treatment by visit week utilizing the computing 
software SAS procedure PROC MIXED.
 
 
 
The primary analysis 
 will be performed on the Efficacy 
Sample.

Key Secondary Efficacy Analysis
The key secondary efficacy variable is the change from baseline to endpoint in the CGI-S 
score, as related to agitation.  It will be analyzed by the same statistical methodology 
specified for the analysis of the primary efficacy variable, based on the ITT population.  
In order to control the overall type I error rate for this key secondary efficacy analysis, a 
hierarchical testing procedure will be used so that the overall experiment-wise type I 
error rate is maintained at 0.05.  Thus, if the primary efficacy analysis for the CMAI total 
score (as described in Section 7.4.1) yields a statistically significant result at 0.05 
(2-sided) for both of the comparisons of brexpiprazole 1 mg/day and 2 mg/day versus 
placebo, then the corresponding comparison for this key secondary efficacy variable 
(CGI-S score) will be tested at an alpha level of 0.05 (2-sided) using another hierarchical 
testing procedure in the order of brexpiprazole 2 mg/day versus placebo and 
brexpiprazole 1 mg/day versus placebo.  Thus, brexpiprazole 1 mg/day versus placebo 
will be tested only if brexpiprazole 2 mg/day versus placebo reaches significance at 0.05 
(2-sided) for this key secondary efficacy variable.

9. 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 progress 
notes, electronic data, screening logs, and recorded data from automated instruments.  All 
source documents pertaining to this trial will be maintained by the investigators. 
Investigator(s)/institution(s) will permit trial-related monitoring, audits, IRB/IEC review, 
and regulatory inspection(s) by providing direct access to source data/documents by 
authorized persons as defined in the ICF.
9.2.
Data Collection
During each subject’s visit to the clinic, a clinician participating in the trial will record 
progress notes to document all significant observations.  At a minimum, these notes will 
contain:

Documentation of the informed consent process, including any revisions

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 assessment of relationship to the IMP must also be recorded.

Any changes in concomitant medications or dosages

A general reference to the procedures completed

The signature (or initials or other unique identifier) and date of each clinician (or 
designee) who made an entry in the progress notes
In addition, any contact with the subject or caregiver via telephone or other means that 
provides significant clinical information will also be documented in the progress notes as 
described above.  Any changes to information in the trial progress notes and other source 
documents will be initialed and dated on the day the change is made by a 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 
clinician.
Until the information herein is released by Otsuka to the public domain, the contents of this document are Otsuka 
confidential information and should not be duplicated or re-distributed without prior written consent of Otsuka.

Information from the trial progress notes and other source documents will be data entered 
by investigative site personnel directly onto eCRFs in the sponsor’s electronic data 
capture system.
9.3.
File Management at the Trial Site
The investigator will ensure that the trial site file is maintained in accordance with 
Section 8 of the ICH GCP guideline and as required by applicable local regulations.  The 
investigator/institution will take measures to prevent accidental or premature destruction 
of these documents.
9.4.
Records Retention at the Trial Site
Regulatory requirements for the archival of records for this trial necessitate that 
participating investigators maintain detailed clinical data for the longest of the following 
3 periods:

A period of at least 2 years following the date on which approval to market the drug 
is obtained (or if IMP development is discontinued, the date regulatory authorities 
were notified of discontinuation).

A period of at least 3 years after the sponsor notifies the investigator that the final 
report has been filed with regulatory authorities.

Longer, region-specific storage requirements, if applicable.
The investigator must not dispose of any records relevant to this trial without either 
(1) written permission from the sponsor or (2) provision of an opportunity for sponsor to 
collect such records.  The investigator will be responsible to maintain adequate and 
accurate electronic or hard copy source documents of all observations and data generated 
during this trial, including the eCRF data on the CD-ROM and any data clarification 
forms received from the sponsor or sponsor’s designee.  Such documentation is subject to 
inspection by the sponsor, sponsor’s designee, and relevant regulatory agencies.  If the 
investigator withdraws from the trial (eg, due to relocation or retirement), all trial-related 
records should be transferred to a mutually agreed-upon designee within a sponsor-
specified time frame.  Notice of such transfer will be given to the sponsor in writing.

Quality Control and Quality Assurance
10.1.
Monitoring
The sponsor has ethical, legal, and scientific obligations to follow this trial carefully in a 
detailed and orderly manner in accordance with established research principles, the ICH 
GCP guideline, and applicable regulatory requirements and local laws.  As part of a 
concerted effort to fulfill these obligations (maintain current personal knowledge of the 
progress of the trial), the sponsor’s monitors will visit the site during the trial, as well as 
communicate frequently via telephone and written communications.
10.2.
Auditing
The sponsor’s Quality Management Unit (or representative) may conduct trial site audits.  
Audits will include, but are not limited to, drug supply, presence of required documents, 
the informed consent process, and comparison of eCRFs with source documents.  The 
investigator agrees to participate with audits.
Regulatory authorities may inspect the investigator 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, the ICH GCP guideline, 
and applicable local laws and regulatory requirements.  Each trial site will seek approval 
by an IRB or IEC according to regional requirements.  The IRB/IEC will evaluate the 
ethical, scientific, and medical appropriateness of the trial.  Further, in preparing and 
handling eCRFs, the investigator, subinvestigator, and their staff will take measures to 
ensure adequate care in protecting subject privacy.  To this end, a subject number and 
subject identification code will be used to identify each subject.
Financial aspects, subject insurance and the publication policy for the trial will be 
documented in the agreement between the sponsor and the investigator.
Until the information herein is released by Otsuka to the public domain, the contents of this document are Otsuka 
confidential information and should not be duplicated or re-distributed without prior written consent of Otsuka.

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(s) where the trial 
is conducted will be met.  However, authorized regulatory officials and sponsor personnel 
(or their representatives) will be allowed full access to inspect and copy the records.  All 
IMPs, subject bodily fluids, and/or other materials collected shall be used solely in 
accordance with this protocol, unless otherwise agreed to in writing by the sponsor.
Subjects will be identified only by initials and unique subject numbers in eCRFs.  Per 
country regulations, if subject initials cannot be collected, another unique identifier will 
be used.  Their full names may, however, be made known to a regulatory agency or other 
authorized officials if necessary.
13.
Amendment Policy
The investigator will not make any changes to this protocol without the sponsor’s prior 
written consent and subsequent approval by the IRB/IEC.  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/IEC.  Except for “administrative” or 
“nonsubstantial” amendments, investigators will wait for IRB/IEC approval 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/IEC notification within 5 working days.  The sponsor will 
submit protocol amendments to the applicable regulatory agencies.
When the IRB/IEC, investigators, and/or the sponsor conclude that the protocol 
amendment substantially alters the trial design and/or increases the potential risk to the 
subject, the currently approved written ICF will require similar modification.  In such 
cases, repeat informed consent will be obtained before expecting continued participation.

Handling and Shipment of Bioanalytical Samples
Pharmacokinetic Sample Collection
Four mL of blood for pharmacokinetic testing will be collected into 4-mL Vacutainer 
tubes containing sodium heparin.  Each tube should be gently inverted three to four times 
and then centrifuged at 2500 rpm for at least 10 minutes at 4°C.  The separated plasma 
from the tube should then be divided equally between the 2 bar-code labeled 
polypropylene tubes.
All tubes must be labeled using the central lab’s bar code labels provided with the sample 
collection kits.  The central lab’s requisition form must be completely filled out in 
regards to the pharmacokinetic sample information.  It is important to note the exact date 
and time of the blood collection, the date and time of the last dose of 
brexpiprazole/placebo prior to each blood draw, and the time of the meal closest to the 
last dose.
The sample must be stored at −70°C, if available, or −20°C or below.  If only a −20°C 
freezer is available, samples must be shipped within 30 days of collection.  Primary and 
backup samples may be shipped together.  If samples are stored in a −70°C freezer, then 
one tube (primary sample) will be shipped on dry ice to the central lab as soon as possible 
after collection.  Following confirmation that the first tube arrived safely, the second tube 
(backup sample) can also be shipped to the central lab.
If neither a −70°C nor −20°C freezer is available, the primary and backup 
pharmacokinetic samples must be shipped on dry ice in the same box to the central 
laboratory on the day of collection.

Pharmacokinetic 
 Sample Shipment
Plasma 
 samples must be neatly packed in the kits provided by the central 
lab and restrained in a Styrofoam container (place Styrofoam container supplied within a 
cardboard box).  Boxes should be completely filled with dry ice to avoid air spaces that 
allow evaporation of the dry ice.  The Styrofoam container should be sealed with tape and 
placed in a cardboard box.  The central laboratory must be alerted of sample shipment.  
Packages must not be shipped on Thursdays, Fridays, Saturdays, or any day prior to a 
holiday without the expressed consent of OPDC.  Shipments from clinical sites will be 
via an overnight carrier to the central laboratory.

Final Paragraph:
Added text:
In addition, the subject will be monitored through actigraphy and eDiary 
assessments as a means of corroborating information recorded on the 
CMAI.  Both assessments will be initiated after the ICF is signed during 
the screening visit and followed through Week 12/ET.  The subjects will 
be given an actigraph, which will record their physical activity, to wear 
on their nondominant wrist for 24 hours/day.  If the subject decides not 
to wear the actigraph at any time after the consent is obtained, the 
assessment may be discontinued and study participation will not be 
affected.  The patient’s daily behavior will be logged into an eDiary by 
the caregiver.

Section 3.7.2 Efficacy Assessments
Paragraph 2:
Added text:
At the time of subject’s screening visit, the caregiver will be provided a 
document which will outline all caregiver responsibilities and their role 
in this study.  The caregiver should acknowledge and agree to undertake 
all the tasks designated by this protocol at the time of the informed 
consent process.
Section 3.7.3.6 Actigraphy
Added section:
The CST will perform ongoing reviews of CMAI raters by reviewing 
CMAI data relative to other sources of behavioral information, 
including patterns of movement using actigraphy technology.  Motion 
will be collected through an actigraphy device resembling a wristwatch 
worn by the subject on their nondominant wrist for 24 hours/day during 
the screening and treatment periods.  If the subject decides not to wear 
the actigraph at any time after the consent is obtained, the assessment 
may be discontinued and continued study participation will not be 
affected.  Study staff will be responsible for uploading actigraphy data 
from the device to the actigraphy vendor at regular intervals 
corresponding to the date of the CMAI assessment. 
Actigraphy uses a portable Motionlogger device (actigraph) that records 
movement over extended periods of time and is most commonly worn on 
the wrist (refer to Appendix 6).  The actigraph accelerometers samples 
physical activity 32 times a second to detect wrist movement.  These data 
are stored within the actigraph for up to several weeks.  The length of 
time the actigraph is able to record data are typically dependent on the 
actigraph’s epoch length (15 seconds, in this study).  The subject is 
advised to wear the actigraph continuously, at all times, including

during sleep.  If the subject must remove the device for any reason, he is 
instructed to place it back on the wrist as soon as possible.  The device is 
able to detect when it is not on the subject’s wrist, and it tracks the time 
that it is not being worn.  An event marker on the device can be used to 
mark the occurrence of significant events such as bedtime, or the time of 
a rating (e.g., such as the CMAI).  The actigraph data will be 
downloaded from the device, verified, and transferred to Clinilabs’ core 
laboratory at each study visit (except the Day 3 visit) by attaching it to a 
docking station connected to a computer that allows communication 
with the software program on the computer.  The computer program 
summarizes these data and can display and print a histogram (called an 
actogram), which shows the subject’s activity levels for each epoch over 
successive 24-hr periods. The computer program provides validated 
algorithms that summarize activity data. The data are then reviewed for 
active periods and rest periods.  The actigraph will be put on the subject
after the ICF/Assent is signed and taken off at the Week 12/ET visit.
Investigator progress notes as well as other efficacy data will be 
reviewed by the CST as part of this in-trial CMAI data quality oversight 
method.  Any clinically relevant findings generated by this review 
suggesting rater training or other issues will be discussed with the sites, 
and measures may be taken to enhance training when needed.  Details 
of this CMAI quality review may be found in the Operations Manual.
Since actigraphy data are tools to assist the CST in monitoring CMAI 
rater training, actigraphy information will not be made available to site 
personnel, and will not be statistically analyzed
Section 3.7.3.7 Electronic Diary (eDiary)
Added section:
The CST will perform ongoing reviews of CMAI raters by reviewing 
CMAI data relative to other sources of behavioral information, 
including daily behavior logs collected by caregivers through eDiaries 
(refer to Appendix 7).  Caregivers will record observations of the 29 
agitated behaviors listed in the CMAI as they occur using an eDiary.  All 
29 behaviors will be listed, and the caregiver will check the box next to 
the behavior when it occurs; there is no free text in the eDiary.

Follow-up Period
All subjects, whether they complete 
the trial or are withdrawn prematurely 
for any reason, will be followed up for 
a safety evaluation at a clinic visit at 
the residential facility 30 (+ 2) days 
after the last dose of the IMP.  If the 
subject has left the residential facility 
where he or she participated in the 
trial, the subject may be seen in the 
investigator’s clinic or (if a clinic visit 
is not possible) assessed by telephone 
contact with the subject and a 
caregiver.
If a subject discontinues the trial 
prematurely, every effort will be made 
to complete the Week 12/ET 
evaluations prior to administering

Section 3.4.1
Informed Consent
Written informed consent will be 
obtained from the subject, if deemed 
capable by the investigator, and 
acknowledgement from the subject’s 
legally acceptable representative, in 
accordance with state and/or local 
regulations, prior to initiation of any 
study protocol-required procedures.  
Alternatively, if the subject is deemed 
incapable of providing consent by the 
investigator, written informed consent 
from the subject’s legally acceptable 
representative and assent from the 
subject will be obtained prior to the 
initiation of any study protocol-
required procedures.  A legally 
acceptable representative is an 
individual or juridical or other body 
authorized under applicable law to 
consent, on behalf of a prospective 
subject, to the subject’s participation 
in the clinical trial.  Further, the 
investigator must assess capacity 
during the screening period and 
throughout the course of the study; if 
the subject is no longer deemed 
capable of providing informed 
consent, informed consent must be 
obtained from the legally acceptable 
representative and assent must be 
obtained from the subject.

terminated from the trial.
Section 3.4.1
Informed Consent
Investigators may discuss trial 
availability and the possibility for 
entry with a potential subject and 
subject’s legally acceptable 
representative without first obtaining 
consent.  However, informed consent 
must be obtained and documented
prior to initiation of any procedures 
that are performed solely for the 
purpose of determining eligibility for 
this trial, including withdrawal from 
current medication(s).
When a study includes subjects who 
may not have the capacity to provide 
informed consent, the investigator will 
be required to assess capacity.  If the 
subject is deemed capable of 
providing informed consent, then the 
subject can be enrolled with the 
consent of the subject.  If the subject is 
deemed to not have the capacity to 
provide informed consent (e.g., 
minors, subjects with severe 
dementia), then the subject can only 
be enrolled with the consent of the 
subject’s legally acceptable 
representative and the subject must be 
informed about the study to the extent 
compatible with the subject’s 
understanding and, if capable, 
personally sign and date the consent or 
assent form, depending on local 
regulations.

questions:  abrupt onset, stepwise 
deterioration, somatic complaints, 
emotional incontinence, history of 
hypertension, history of stroke, focal 
neurologic signs, and focal neurologic 
symptoms.  The Rosen-modified 
Hachinski Ischemic Scale will be

Clinical Global Impression-Severity of Illness (CGI-S), as related to agitation
ADDITIONAL RISK TO THE SUBJECT:
The addition of the requirement for performing an MRI/CT scan of the brain during 
screening to confirm eligibility for enrollment in the study does pose some additional 
risk to these subjects; however, the sponsor has determined that the benefit derived 
from confirming the diagnosis of Alzheimer’s disease and from ruling out other causes 
for dementia in the subjects enrolled in this study outweighs the risks to the subjects.

Amendment Number:
3
Issue Date:
07 Jul 2014
PURPOSE:
The sponsor has determined the need for a third formal amendment to the second 
amendment of the original protocol.  This amendment serves to reflect clarifications and 
additions to study procedures intended to enhance subject safety and accuracy of data.  In 
addition, administrative clarifications were made, including changes to text to enhance 
readability and consistency, and changes to correct typographical, punctuation, and 
formatting errors.  These changes were minor and do not change the design or content of 
the protocol, and therefore, are not summarized in this appendix.
The purpose of amending Protocol 331-12-283, issued 16 Dec 2013, was to:

 

 
 
 

Allow the inclusion of non-institutionalized subjects.

Clarify the caregiver/caretaker requirements.

Modify the Neuropsychiatric Inventory-Nursing Home scale (NPI-NH) by replacing 
the Occupational Disruptiveness NPI-NH questions with the Distress questions from 
the Neuropsychiatric Inventory (NPI) for subjects in a non-institutionalized setting.

Add the Resource Utilization in Dementia (RUD) assessment for both 
non-institutionalized and institutionalized subjects.

Increase the number of planned trial centers from 55 to 75.

Modify inclusion criteria #6 and #7.

Modify exclusion criteria #8, #13, #14, #31, #32, and #40.

Remove exclusion criterion #27 (this resulted in renumbering of exclusion criteria 
#28 through #41).

Change the analysis of the primary and key secondary endpoints from the Hochberg 
procedure to a hierarchical testing procedure.

Add another primary medical contact.

Change the medical monitor for Europe.

when making 2 comparisons of 
brexpiprazole doses versus placebo, 
the statistical testing will be carried 
out using Hochberg’s procedure for 
the primary efficacy endpoint.  The 
alpha used in the analysis of the key 
secondary endpoint is 0.05 (2-sided), 
if both of the comparisons of the 
higher dose groups versus placebo in 
the primary efficacy endpoint are 
statistically significant under the 
Hochberg procedure.
The Hochberg procedure at the alpha 
level of 0.05 (2-sided) will be used for

significance is claimed in 
Step 1.
The sample size was calculated based 
on the treatment effect of 6.5 points 
with an SD of 16.5 in the change from 
baseline to the endpoint in the CMAI 
total score, to achieve 80% power at a 
2-sided alpha level of 0.025 adjusted 
for 2 comparisons versus placebo 
(brexpiprazole 1 mg/day versus 
placebo and brexpiprazole 2 mg/day 
mg/day versus placebo.  To protect the 
experiment wise alpha level at 0.05 
when making 2 comparisons of 
brexpiprazole doses versus placebo, the 
statistical testing will be carried out 
using a hierarchical testing procedure 
in the order of 1) comparison of 2 
mg/day brexpiprazole versus placebo 
and 2) comparison of 1 mg/day 
brexpiprazole versus placebo.  Thus, if 
the test yields a statistically significant 
result at 0.05 (2-sided) for the 
comparison of 2 mg/day brexpiprazole 
versus placebo, then the comparison of 
1 mg/day brexpiprazole versus placebo 
will be tested at an alpha level of 0.05 
(two sided) Hochberg’s procedure for 
the primary efficacy endpoint.  The 
alpha used in the analysis of the key 
secondary endpoint is 0.05 (2-sided), 
if both of the comparisons of the 
higher dose groups versus placebo in 
the primary efficacy endpoint are 
statistically significant under the 
Hochberg procedure.
If the primary efficacy analysis for the 
CMAI total score yields a statistically 
significant result at 0.05 (2-sided) for 
both of the comparisons of 
brexpiprazole 1 mg/day and 2 mg/day 
versus placebo, then the corresponding 
comparison for the key secondary 
efficacy variable (CGI-S score) will be 
tested at an alpha level of 0.05 (two-
sided) using another hierarchical 
testing procedure in the order of 
brexpiprazole 2 mg/day versus placebo 
and brexpiprazole 1 mg/day versus 
placebo.  Thus, brexpiprazole 1 
mg/day versus placebo will be tested 
only if brexpiprazole 2 mg/day versus 
placebo reaches significance at 0.05 
(2-sided) for this key secondary 
efficacy variable.

Brexpiprazole has been well tolerated 
by healthy volunteers at single doses 
up to 6 mg and at multiple doses up to

with another marketed medication.  
The most frequently reported TEAEs 
(incidence ≥ 5% of the total 
brexpiprazole group and more than

who received brexpiprazole were 
dizziness (8.7%), insomnia (7.0%), 
nausea (6.2%), and akathisia (5.8%).  
In the total placebo group, headache 
(9.8%) was the most frequently

group.
One death has been reported in the 25 
trials completed under the US INDs as 
of the 20 Sep 2012 cutoff date.  This 
death occurred 12 days after the 
subject received the last dose of 
brexpiprazole in the phase 2, double-
blind schizophrenia trial (Trial 331-
07-203), and the death was not 
considered by the investigator to be 
not related to the IMP.  One additional 
death was reported in the ongoing, 
phase 2, open-label MDD trial 
(Trial 331-08-212).  The subject was 
reported to have died from progressive 
metastatic disease approximately 2 
months after the initial onset of the 
event (81 days after the last dose of 
the IMP).  The event was assessed as 
not related to the IMP by the 
investigator.

Trial Rationale
In light of the Food and Drug 
Administration (FDA) boxed warning 
of increased mortality with the use of 
antipsychotics in elderly subjects with 
dementia-related psychosis and 
similar caution advised by other 
regulatory authorities, the clinical trial 
will be conducted in an environment 
that allows for close safety 
monitoring, specifically in subjects 
who are residing in a dementia unit, 
nursing home, assisted living facility, 
or any other residential care facility 
providing long-term care.  The 
settings will provide the type of 
medically supervised environment 
needed to closely monitor trial 
participants, particularly for events 
related to cardiac and pulmonary 
disease that may contribute to the risk 
of increased death.

Null (new section)
3.3.1.1  Non-institutionalized Subjects 
In a non-institutionalized setting, the 
subject’s caretaker is the person who 
lives with and cares for the subject on 
a regular basis.  For example, caring 
for a subject on a regular basis may 
include the following activities:  
assisting with dispensing of IMP; 
observing the subject’s general 
medical condition, including nutrition 
and hydration intake; reducing the 
chance of fall; and assisting the 
subject if emergency medical care is 
needed by contacting appropriate 
emergency services, the subject’s 
primary physician, or the principal 
investigator, whatever is warranted.  
The caretaker may be supported in 
providing care to the subject by a 
professional(s), friend(s), or family 
member(s).
The subject’s caregiver is defined as 
the person who has sufficient contact 
to describe the subject’s symptoms, 
and has direct observation of the 
subject’s behavior in order to 
participate in the interview for the 
CMAI, NPI-NH, NPI/NPI-NH, and 
other applicable trial assessments, 
including completion of the eDiary.  A 
caregiver must be identified during the 
screening period for participation in 
the interview of the applicable trial 
assessments.  At the time of the 
subject’s screening visit, the caregiver 
will be provided a document that will 
outline all caregiver responsibilities.

not be the same individual who fulfills 
the role of caretaker depending on the 
circumstances of the subject.  The 
recommended minimum level of 
contact between the caregiver and the 
subject is 2 hours per day for 4 days

arrangements are made and approved 
by the sponsor.
3.3.1.2  Institutionalized Subjects 
In the institutionalized setting, there is 
only one role defined and that is the 
role of caregiver.  A caregiver in the 
institutionalized setting is an 
individual who has sufficient contact 
to describe the subject’s symptoms and 
who has direct observation of the 
subject’s behavior in order to

Section 3.4.1.1
Determinations of 
Capacity
The investigator must assess the 
capacity of the subject to provide 
informed consent during the screening 
period and throughout the course of 
the study.  Once these determinations 
are made by the investigator, the 
following options for obtaining 
informed consent from and/or on 
behalf of the subject must be 
followed:

If the subject is deemed capable 
by the investigator, written 
informed consent will be obtained 
from the subject prior to the 
initiation of any study protocol-
required procedures.  In such 
cases, acknowledgement from the 
subject’s legally acceptable 
representative (an individual, or 
judicial or other body, authorized 
under applicable law to consent to 
the subject’s participation in the 
clinical trial on behalf of that 
prospective subject) will also be 
obtained in accordance with state 
and/or local regulations prior to 
initiation of any study protocol-
required procedures.

If the subject was initially deemed 
capable of providing informed 
consent but is no longer deemed 
so, informed consent must be 
obtained from the subject’s 
legally acceptable representative, 
and assent from the subject, if 
possible, will be confirmed in 
accordance with state and/or local 
regulations prior to the initiation 
of any study protocol-required 
procedures.  
...

If the subject initially provided 
assent at study entry, but 
subsequent dissents to participate 
in the trial, the subject will be 
early terminated from the trial.

the last dose of IMP during a clinic visit at either the investigator’s site or residential facility 30 (+ 2) days after the last dose of IMP.  If the 
institutionalized subject has left the residential facility where he or she participated in the trial, the subject should be seen atin the investigator’s site.clinic
or (if If a clinic visit is not possible), the subject should be assessed by telephone contact with the subject and a caregiver.  Subjects who complete both the 
12-week double-blind treatment period and the 30-day safety follow-up visit are eligible to enroll into Trial 331-13-211, which is a 2-month, observational, 
rollover trial to evaluate the safety of subjects with agitation associated with Alzheimer's disease who previously participated in Trial 331-12-283.  For 
those subjects who plan to enroll into Trial 331-132-211, the 30-day safety follow-up visit for Trial 331-12-283 will occur as a clinic visit at either the 
investigator’s site or residential facility.  If the institutionalized subject has left the residential facility where he or she participated in the trial, the 30-day 
safety follow-up visit will occur as a clinic visit at the investigator's site.

xPharmacokinetic samples will be obtained at baseline and at any time during the Week 8 and Week 12/ET visits.  If blood samples for clinical laboratory 
tests are not collected at the baseline visit, pharmacokinetic samples do not need to be obtained at baseline.  Every possible effort should be made to collect 
samples at the same time at each visit.  The subject should be advised to take the IMP at approximately the same time each day throughout the trial, but

taken during the trial will be recorded as concomitant medications.  Details of prohibited and restricted medications are provided in the protocol (refer to 
Section 4.1).  During the first 4 weeks of the randomized phase (baseline to Week 4 visit), benzodiazepines are allowed but limited to 4 days/week with a 
maximum dose of 2 mg/day of lorazepam (or equivalent) or less depending on dose-limiting side effects.  Benzodiazepines must not be administered 
within 12 hours prior to the efficacy and safety scales.  After the Week 4 visit, benzodiazepines are prohibited.

with IMP, confirm any changes to concomitant medications, and assure the subject’s well-being.
bbddIf a previous MRI or CT scan of the brain performed after the onset of symptoms of dementia is not available, then an MRI/CT scan of the brain should 
be performed during screening.  In addition, a repeat MRI/CT scan of the brain may be requested to be performed 
 in order to confirm 
eligibility.

Neuropsychiatric 
Inventory  (NPI)
Null (new section)
The NPI is a structured caregiver 
interview designed to obtain 
information on the presence of 
psychopathology in subjects with brain 
disorders, including Alzheimer’s 
disease and other dementias.31  The 
NPI differs from the NPI-NH in that it 
is tailored for use in non-institutional 
settings (as opposed to the nursing 
home).  Item domains are identical 
between the two scale versions.  Ten 
behavioral and two neurovegetative 
symptom domains comprise the NPI 
(including delusions, hallucinations, 
agitation/aggression, 
depression/dysphoria, anxiety, 
elation/euphoria, apathy/indifference, 
disinhibition, irritability, aberrant 
motor behavior, nighttime behavior 
disorders, and appetite/eating 
disorders).  Caregivers are instructed 
to indicate the frequency of a given 
behavior (on a scale of 1 to 4), its 
severity (on a scale of 1 to 3), and how 
much distress that behavior causes for 
him or her (on a scale of 0 to 5).  Each 
domain produces 4 scores:  frequency, 
severity, total (frequency x severity), 
and distress.  A total NPI score is 
calculated by adding the first 10 
domain total scores (frequency x 
severity scores) together. All 12 
domain total scores can be summed in 
special circumstances where the 
neurovegetative symptoms are of 
particular importance.  Administering 
the NPI generally takes about 15 
minutes.  The psychometric properties 
and factor structure of the NPI have 
been shown to have internal 
consistency, reliability, convergent 
validity, and discriminant validity.
A sample of the NPI is provided in 
Appendix 11.

Section 3.11
Definition of Subjects 
Lost to Follow-up
Subjects who cannot be contacted on 
or before the Week 12 visit during the 
treatment period and who do not have 
a known reason for discontinuation 
(e.g., withdrew consent or AE) will be 
classified as “lost to follow-up.”  If a 
subject leaves the residential facility 
in which he/she was residing before 
completion of the study, the site will 
make 3 attempts to contact the subject 
by telephone; 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.

be followed for non-institutionalized 
subjects who are lost to follow-up.
Section 3.12
Subject Compliance
Responsible trial personnel will 
dispense the IMP (i.e., brexpiprazole 
or matching placebo).  Accountability 
and compliance verification should be 
documented in the subject’s trial 
records.
Responsible trial personnel will 
dispense the IMP (i.e., brexpiprazole or 
matching placebo) according to the 
visits outlined in the Schedule of 
Assessments (Table 3.7-1).  
Accountability and compliance 
verification should be documented in 
the subject’s trial records.
For non-institutionalized subjects, the 
caretaker or caregiver may administer 
IMP to the subject, as long as the 
subject is compliant with IMP dosing 
requirements.
For institutionalized subjects, the 
caregiver will be responsible for 
administering IMP to the subject.  It 
may be possible that there is more than 
one caregiver for a subject.  The 
caregiver(s) should be appropriately 
instructed to ensure that the subject is 
compliant with IMP dosing 
requirements.

Sample Size
The sample size was calculated based 
on the treatment effect of 6.5 points 
with a standard deviation (SD) of 16.5 
in the change from baseline to the 
endpoint in the CMAI total score, to 
achieve 80% power at a 2-sided alpha 
level of 0.025 adjusted for 2 
comparisons versus placebo 
(brexpiprazole 1 mg/day versus 
placebo and brexpiprazole 2 mg/day 
versus placebo).  The resulting sample 
size is 124 subjects in each of the 
groups mentioned above (i.e., 
brexpiprazole 2 mg/day, brexpiprazole 
1 mg/day, and placebo), which can 
achieve overall greater than 90% 
power (at least one high dose group is 
significant).  To account for a portion 
of subjects who discontinue 
prematurely and whose data may 
potentially dilute the treatment effect, 
approximately an additional 10% of 
subjects was added to the sample size, 
resulting in a sample size of 140 
subjects in each treatment group, 
which means the total sample size is 
560 subjects.

Section 7.4.1
Primary Efficacy 
Analysis
The primary endpoint will be analyzed 
using a mixed-effect model repeated 
measure (MMRM) model.  The 
primary efficacy outcome measure is 
the mean change from baseline to the 
endpoint in the CMAI total score.  
Details of sensitivity analyses under 
the assumption of missing not at 
random (MNAR) will be provided in 
the SAP. ... To protect the experiment-
wise 2-sided alpha level at 0.05 when 
making 2 comparisons of 
brexpiprazole doses versus placebo, 
the statistical testing will be carried 
out using Hochberg’s procedure.
The statistical comparison will be 
performed by the MMRM analysis 
with an unstructured variance 
covariance matrix for the repeated 
measures in which the change from 
baseline to endpoint in CMAI total 
score will be the dependent variable 
based on the OC dataset.  The model 
will include fixed class-effect terms 
for treatment, trial center, visit week, 
and an interaction term of treatment 
by visit week and include the 
interaction term of baseline by visit 
week as a covariate.  
The primary endpoint will be analyzed 
using a mixed-effect model repeated 
measure (MMRM) model.  The primary 
efficacy outcome measure is the mean 
change from baseline (Day 0 visit) to 
the end of the double-blind treatment 
period (Week 12 visit) to the endpoint
in the CMAI total score.  
 
.  
... To protect the experiment-wise 
2-sided alpha level at 0.05 when 
making 2 comparisons of brexpiprazole 
doses versus placebo, the statistical 
testing will be carried out using 
Hochberg’s procedure a hierarchical 
testing procedure in the order of 1) 
comparison of 2 mg/day brexpiprazole 
versus placebo and 2) comparison of 1 
mg/day brexpiprazole versus placebo.  
Thus, if the test yields a statistically 
significant result at 0.05 (2-sided) for 
the comparison of 2 mg/day 
brexpiprazole versus placebo, then the 
comparison of 1 mg/day brexpiprazole 
versus placebo will be tested at an 
alpha level of 0.05 (2-sided).

which the change from baseline (Day 0 
visit) to endpoint in CMAI total score 
(at Weeks 2, 4, 6, 8, 10, and 12) will be
the dependent variable based on the OC 
dataset.  The model will include fixed 
class-effect terms for treatment, trial 
center, visit week, and an interaction 
term of treatment by visit week and 
include the interaction term of baseline 
values of CMAI total score by visit 
week as a covariate.  The primary 
comparison between brexpiprazole and

Section 7.4.2
Key Secondary 
Efficacy Analysis
The key secondary efficacy variable is 
the change from baseline to endpoint 
in the Clinical Global Impression-
Severity of Illness (CGI-S) score, as 
related to agitation.  It will be 
analyzed by the same statistical 
methodology specified for the analysis 
of the primary efficacy variable, based 
on the ITT population.  The alpha 
used in the analysis of this key 
secondary endpoint is 0.05 (2-sided), 
if both of the comparisons of the 
higher dose groups versus placebo in 
the primary efficacy endpoint are 
statistically significant under the 
Hochberg procedure.

procedure will be used so that the 
overall experiment-wise type I error 
rate is maintained at 0.05.  Thus, if the

Section 7.4.1) yields a statistically 
significant result at 0.05 (2-sided) for 
both of the comparisons of 
brexpiprazole 1 mg/day and 2 mg/day 
versus placebo, then the corresponding 
comparison for this key secondary 
efficacy variable (CGI-S score) will be 
tested at an alpha level of 0.05 (2-
sided) using another hierarchical 
testing procedure in the order of 
brexpiprazole 2 mg/day versus placebo 
and brexpiprazole 1 mg/day versus 
placebo.  Thus, brexpiprazole 1 
mg/day versus placebo will be tested 
only if brexpiprazole 2 mg/day versus 
placebo reaches significance at 0.05

Amendment Number:
4
Issue Date:
10 Sep 2015
PURPOSE:
The sponsor has determined the need for a fourth formal amendment.  This amendment 
serves to reflect clarifications and changes to trial procedures intended to enhance subject 
safety and accuracy of data, as well as to streamline the exclusion criteria.  In addition, 
administrative clarifications were made, including changes to text to enhance readability 
and consistency, and changes to correct typographical, punctuation, and formatting 
errors.  These changes were minor and do not change the design or content of the 
protocol, and therefore, are not summarized in this appendix.
The purpose of amending Protocol 331-12-283, issued 07 Jul 2014, was to:

Increase the number of screened subjects from 560 to 840 and the number of 
trial sites from 75 to 85.

Increase the time from enrollment of first subject to last subject’s last trial visit from 
4 to 4.5 years and the time for recruitment from 3.5 to 4 years.

Broaden the definition of subjects in an institutionalized setting and add overnight 
passes (at the investigator’s discretion) for these subjects.

Broaden the location of trial visits.

Add that the screening period can be extended or that subjects can be rescreened more 
than once with the approval of the medical monitor.

Modify inclusion criterion #8.

Modify exclusion criteria #1, 3, 7, 8, 11, 13, 18, 21, 23, 30, 33, 36, and 39, and 
remove exclusion criteria #4, 5, 9, 14, 17, 19, 20, 22, and 24-27.  These modifications 
resulted in the renumbering of the exclusion criteria. 

Remove HIV testing at screening.

Remove urinalysis, prolactin, and urine pregnancy testing at Week 4 and Week 8.


 

Change telephone contact to Weeks 3, 5, and 7 during the double-blind treatment 
period.

Change electronic diaries to paper diaries, as well as remove the diary line item from 
Table 3.7-1 (Schedule of Assessments), remove Section 3.7.3.8 (Electronic Diary), 
and remove Appendix 7 (Electronic Diary).

Remove actigraphy from the trial.

Synopsis
Trial Design
...The trial population will include 
male and female subjects between 
55 and 90 years of age (inclusive), 
who are living in either an 
institutionalized setting (e.g., nursing 
home, dementia unit, assisted living 
facility, or any other residential care 
facility providing long term care) or in 
a non-institutionalized setting where 
the subject is not living alone.
...
Screening Period:
The screening period will range from 
a minimum of 2 days to a maximum 
of 42 days and will begin when the 
informed consent form (ICF) is 
signed, prior to the initiation of any 
procedures.  
...
12-week, Double-blind Treatment 
Period:
...
The subjects’ condition will be 
evaluated routinely, including vital 
signs assessments, as required per the 
local guidelines of the institutionalized 
setting or according to the discretion 
of the principal investigator.  Subjects 
will be evaluated at Baseline, Day 3, 
and at Weeks 2, 4, 6, 8, 10, and 12 
during the double-blind treatment 
period.  All study visits will take place 
as a clinic visit at either the 
investigator’s site (for 
non-institutionalized subjects) or 
residential facility (for 
institutionalized subjects).  In 
addition, the subject’s identified 
caregiver will be contacted by 
telephone  every odd numbered week 
after Week 2 (i.e., Weeks 3, 5, 7, 9, 
11) to assess compliance with IMP, 
confirm any changes to concomitant 
medications, and assure the subject’s

Section 2.1
Trial Rationale
In light of the Food and Drug 
Administration (FDA) boxed warning 
of increased mortality with the use of 
antipsychotics in elderly subjects with 
dementia-related psychosis and 
similar caution advised by other 
regulatory authorities, the clinical trial 
will be conducted in an environment 
that allows for close safety 
monitoring, in subjects who are living 
in either an institutionalized setting 
(e.g., nursing home, dementia unit, 
assisted living facility, or any other 
residential care facility providing long 
term care) or in a non-institutionalized 
setting where the subject is not living 
alone and has a caregiver who can 
spend a minimum of 2 hours per day 
for 4 days per week with the subject in 
order to assess changes in the 
subject’s condition.

through Week 12/Early Termination 
(ET).  The subjects will be given an 
actigraph, which will record their 
physical activity, to wear on their 
nondominant wrist for 24 hours/day.  
If the subject decides not to wear the 
actigraph at any time after the consent 
is obtained, the assessment may be 
discontinued and study participation 
will not be affected.  The subject’s 
behavior will be logged into an eDiary 
by the caregiver and/or facility staff.
staff.  This diary data along with the 
collection of progress notes will be sent 
to the CST group on a routine basis in 
order to corroborate information 
recorded on the CMAI.  Since the diary 
data is a tool to assist the CST in 
monitoring CMAI rater training, the 
diary data will not be statistically 
analyzed.
While it is preferred that diary data are 
collected 7 days a week, it is realized 
that diary use for 7 days a week may 
not be possible because the minimum 
amount of time that the caregiver is 
required to observe the subject is 4 days 
a week.  Every effort should be put 
forth by the sites to encourage the 
caregivers to collect and submit as 
much data as possible.  Caretakers, 
facility personnel, and/or family 
members may provide information to 
the caregiver to complete the diary, but 
this is not a requirement.
Details around this procedure can be 
found in the operations manual.

the trial or are withdrawn prematurely 
for any reason, will be followed up for 
a safety evaluation 30 (+ 2) days after 
the last dose of IMP during a clinic 
visit at either the investigator’s site or 
residential facility.  If the 
institutionalized subject has left the 
residential facility where he or she 
participated in the trial, the subject 
should be seen at the investigator’s 
site. ... For those subjects who plan to 
enroll into Trial 331-13-211, the 
30-day safety follow-up visit for Trial 
331-12-284 will occur as a clinic visit 
at either the investigator’s site or

kAfter the ICF is signed during the 
screening visit, the actigraphy device 
will be put on the subject’s 
nondominant wrist and worn daily 
until Week12/ET.  It is recommended 
that the actigraph be checked daily to 
ensure that the subject is wearing it 
and that it continues to be operational.  
At every study visit (except the Day 3 
visit), subjects will take off the watch 
so that site personnel can download 
the data stored in the device, and the 
device battery will be changed.  If the 
screening period extends beyond 
4 weeks, the battery will need to be 
replaced once.  Once the download is 
complete, the device will be placed 
back on the subject.

psychopathology in subjects with 
brain disorders, including Alzheimer’s 
disease and other dementias.31  The 
NPI differs from the NPI-NH in that it 
is tailored for use in non-institutional 
settings (as opposed to the nursing 
home).  Item domains are identical 
between the two scale versions.  
Ten behavioral and two 
neurovegetative symptom domains 
comprise the NPI (including 
delusions, hallucinations, 
agitation/aggression, 
depression/dysphoria, anxiety, 
elation/euphoria, apathy/indifference, 
disinhibition, irritability, aberrant 
motor behavior, nighttime behavior 
disorders, and appetite/eating 
disorders).  Caregivers are instructed 
to indicate the frequency of a given 
behavior (on a scale of 1 to 4), its 
severity (on a scale of 1 to 3), and how 
much distress that behavior causes for 
him or her (on a scale of 0 to 5).  Each 
domain produces 4 scores:  frequency,
severity, total (frequency x severity), 
and distress.  A total NPI score is 
calculated by adding the first 
10 domain total scores (frequency x 
severity scores) together.  All 
12 domain total scores can be summed 
in special circumstances where the 
neurovegetative symptoms are of 
particular importance.  Administering 
the NPI generally takes about 15 
minutes.  The psychometric properties 
and factor structure of the NPI have 
been shown to have internal 
consistency, reliability, convergent 
validity, and discriminant validity.
A sample of the NPI is provided in 
Appendix 9.
caregiver interview designed to obtain 
information on the presence of 
psychopathology in non-
institutionalized subjects with brain 
disorders, including Alzheimer’s 
disease and other dementias.31  The 
NPI/NPI-NH differs from the NPI-NH 
in that questions referring to 
“Occupational Disruptiveness” from the 
NPI-NH have been replaced with 
questions referring to “Distress” from 
the Neuropsychiatric Inventory (NPI).  
Item domains are identical between the 
NPI/NPI-NH and NPI-NH.  
Ten behavioral and two neurovegetative 
symptom domains comprise the 
NPI/NPI-NH (ie, delusions, 
hallucinations, agitation/aggression, 
depression/dysphoria, anxiety, 
elation/euphoria, apathy/indifference, 
disinhibition, irritability, aberrant motor 
behavior, nighttime behavior disorders, 
and appetite/eating disorders).  The 
identified caregivers are instructed to 
indicate the frequency (on a scale of 1 
to 4), severity (on a scale of 1 to 3), and 
distress (on a scale of 0 to 5) of each of 
the 12 separate behavioral domains.  
Therefore, for each behavioral domain, 
there are 4 scores:  frequency, severity, 
total (frequency x severity), and 
distress.  A total NPI/NPI-NH score is 
calculated by adding the first 10 domain 
total scores (frequency x severity 
scores) together.  All 12 domain total 
scores can be summed in special 
circumstances where the 
neurovegetative symptoms are of 
particular importance.  Administering 
the NPI/NPI-NH generally takes about 
15 minutes.  
A sample of the NPI/NPI-NH is 
provided in Appendix 11.

patterns of movement using 
actigraphy technology.  Motion will 
be collected through an actigraphy 
device resembling a wristwatch worn 
by the subject on their nondominant 
wrist for 24 hours/day during the 
screening and treatment periods.  If 
the subject decides not to wear the 
actigraph at any time after the consent 
is obtained, the assessment may be 
discontinued and continued study 
participation will not be affected.  The 
actigraphy data will be downloaded 
from the device to the actigraphy 
vendor at regular intervals 
corresponding to the date of the CMAI 
assessment.  For non-institutionalized 
subjects, the caregiver will not be 
expected to change the actigraph 
watch battery or download the 
actigraphy data; these duties will be 
completed by the site staff.  For 
institutionalized subjects, the 
caregiver or site staff may be 
responsible for changing the actigraph 
watch battery or downloading the 
actigraphy data.  
Actigraphy uses a portable 
Motionlogger device (actigraph) that 
records movement over extended 
periods of time and is most commonly 
worn on the wrist (refer to Appendix 
6).  The actigraph accelerometers 
samples physical activity 32 times a 
second to detect wrist movement.  
These data are stored within the 
actigraph for up to several weeks.  The 
length of time the actigraph is able to 
record data are typically dependent on 
the actigraph’s epoch length (15 
seconds, in this study).  The subject is 
advised to wear the actigraph 
continuously, at all times, including 
during sleep.  If the subject must 
remove the device for any reason, the 
subject is instructed to place it back on 
the wrist as soon as possible.  The 
device is able to detect when it is not 
on the subject’s wrist, and it tracks the 
time that it is not being worn.  An 
event marker on the device can be 
used to mark the occurrence of

significant events such as bedtime, or 
the time of a rating (e.g., such as the 
CMAI).  The actigraphy data will be 
downloaded from the device, verified, 
and transferred to Clinilabs’ core 
laboratory at each study visit (except 
the Day 3 visit) by attaching it to a 
docking station connected to a 
computer that allows communication 
with the software program on the 
computer.  The computer program 
summarizes these data and can display 
and print a histogram (called an 
actogram), which shows the subject’s 
activity levels for each epoch over 
successive 24-hr periods.  The 
computer program provides validated 
algorithms that summarize activity 
data.  The data are then reviewed for 
active periods and rest periods.  The 
actigraph will be put on the subject 
after the ICF/assent is signed and 
taken off at the Week 12/ET visit.
Investigator progress notes as well as 
other efficacy data will be reviewed 
by the CST as part of this in-trial 
CMAI data quality oversight method.  
Any clinically relevant findings 
generated by this review suggesting 
rater training or other issues will be 
discussed with the sites, and measures 
may be taken to enhance training 
when needed.  Details of this CMAI 
quality review may be found in the 
Operations Manual.
Since actigraphy data are tools to 
assist the CST in monitoring CMAI 
rater training, actigraphy information 
will not be statistically analyzed.

setting, one of the responsibilities of 
the caregiver is to complete the eDiary 
by noting the subject’s symptoms of 
agitation.  While it is preferred that 
eDiary data are collected 7 days a 
week, it is realized that eDiary use for 
7 days a week may not be possible 
because the minimum amount of time 
that the caregiver is required to 
observe the subject is 4 days a week.  
The caretaker may provide 
information to the caregiver to 
complete the eDiary on a daily basis, 
but this is not a requirement.  The 
responsibility of the caregiver for 
logging behaviors in the eDiary 
remains the same for subjects in an 
institutionalized setting.  However, 
more than one caregiver may use the 
eDiary for any given subject; whoever 
is providing care for the subject at a 
given time can log behaviors in the 
eDiary.  
...
Since eDiary data are tools to assist 
the CST in monitoring CMAI rater 
training, eDiary information will not 
be statistically analyzed.

Appendix 6
Actigraphy 
Description
Actigraphy utilizes a portable device 
(actigraph) that records movement 
with a piezoelectric accelerometer 
over extended periods of time and is 
worn most commonly on the 
nondominant wrist.  The actigraph 
accelerometers samples physical 
activity 32 times a second to detect 
wrist movement.  These data are 
stored within the actigraph for up to 
several weeks.  The length of time the 
actigraph is able to record data are 
typically dependent on the actigraph’s 
epoch length (15 seconds, in this 
study).  The subject is advised to wear 
the actigraph continuously, at all 
times, including during sleep 
beginning after the informed consent 
is signed to Week 12/ET.  If the 
subject must remove the device for 
any reason, the subject is instructed to 
place it back on the wrist as soon as 
possible.  The device is able to detect 
when it is not on the subject’s wrist, 
and it tracks the time that it is not 
being worn.  The actigraphy data will 
be downloaded from the device, 
verified, and transferred to Clinilabs’ 
core laboratory at each study visit 
(except the Day 3 visit)  by attaching 
it to a docking station connected to a 
computer that allows communication 
with the software program on the 
computer.  A computer program 
summarizes these data and can display 
and print a histogram (called an 
actogram), which shows the subject’s 
activity levels for each epoch over 
successive 24-hour periods.  The
computer program provides validated 
algorithms that summarize activity 
data.  The data are then reviewed for 
active periods and rest periods.
In addition, activity will be analyzed 
over each 24-hour period (“Daily” 
intervals) for maximum, total and 
average activity levels to understand 
the amount of day time movement 
from the subject and to evaluate 
restlessness, agitation, and increased 
random movements like those seen in 
akathisia.  Raw activity data will also

be generated that allows the total 
number of epochs with zero activity 
counts to be calculated during baseline 
and treatment period for both groups 
over each 24-hour period.  In addition, 
for non-zero epochs, the mean activity 
can be calculated over each 24-hour 
period.
To evaluate the diurnal activity 
patterns, the activity counts for one-
hour blocks at 8:00 am, 12:00 pm, 
4:00 pm, and 8:00 pm will be 
provided.  This will provide for the 
possibility of measuring “time of day” 
specific activity related to agitation.  
Since actigraphy will be collected 
twenty four hours per day for 
extended periods of time, sleep 
parameters will be evaluated as a 
continuous evaluation of these 
multiple day indices.  Sleep-wake 
patterns are estimated from periods of 
activity and inactivity based on this 
movement during the rest period.  
Actigraphy is based on the principle 
that there is reduced movement during 
sleep and increased movement during 
wake.  The computer programs can 
estimate sleep and wake based upon 
computer algorithm-defined 
thresholds of activity.  Thus, the 
estimated sleep-wake parameters such 
as sleep latency, total sleep time, 
number and frequency of awakenings, 
sleep efficiency can be derived.  
Circadian rhythm parameters, such as 
the amplitude (peak-to-nadir 
difference) or acrophase (time of peak 
activity), can also be typically 
obtained.

Introduction
This statistical analysis plan (SAP) documents the statistical methodology and data 
analysis algorithms and conventions to be applied for statistical analysis and reporting of 
efficacy and safety data of study 331-12-283.  All amendments to the protocol and 
Addendum to protocol amendment are taken into consideration in developing this SAP.
2
Trial Objectives
Primary: To compare the efficacy of 2 fixed doses (1 mg/day and 2 mg/day) of 
brexpiprazole with placebo in subjects with agitation associated with dementia of the 
Alzheimer’s type, as assessed by the CMAI after 12 weeks of treatment.
Secondary: To evaluate the safety and tolerability of 2 fixed doses of brexpiprazole (1 
mg/day and 2 mg/day) compared with placebo in subjects with agitation associated with 
dementia of the Alzheimer’s type after 12 weeks of treatment.
3
  Trial Design
This is a phase 3, 12-week, multicenter, randomized, double-blind, placebo-controlled, 3-
arm, fixed-dose trial designed to assess the efficacy, safety, and tolerability of 
brexpiprazole (1 mg/day and 2 mg/day) in the treatment of subjects with agitation 
associated with dementia of the Alzheimer’s type. The trial population will include male 
and female subjects between 55 and 90 years of age (inclusive), who are living in either
an institutionalized setting or in a non-institutionalized setting where the subject is not 
living alone. In both the institutionalized and non-institutionalized settings, the subject 
must have a caregiver who can spend a minimum of 2 hours per day for 4 days per week 
with the subject in order to assess changes in the subject’s condition. All subjects must 
have a diagnosis of probable Alzheimer’s disease according to the National Institute of 
Neurological and Communicative Disorders and Stroke and the Alzheimer’s Disease and 
Related Disorders Association (NINCDS-ADRDA) criteria. 
The trial comprises a 2- to 42-day screening period, a 12-week double-blind treatment 
period, and a 30-day post-treatment follow-up period. In addition, for all subjects who 
terminate early from the trial, all attempts will be made to collect mortality data by 
telephone contact with the subject’s caregiver at Week 16.
This trial will be monitored under the supervision of an independent Data Monitoring 
Committee (DMC). The DMC will monitor safety periodically, based on a predetermined 


SAP 331-12-283
Confidential - Proprietary Information  
6
March 14, 2017
schedule. The details of the DMC structure and its roles and responsibilities will be 
documented in a DMC charter. 
The trial is organized as follows:
Screening Period
The screening period will range from 2 days to 42 days and will begin when the informed 
consent form (ICF) is signed, prior to the initiation of any procedures. The screening 
period may be extended after discussion with and approval by the medical monitor. An 
interactive voice response system (IVRS) or interactive web response system (IWRS) will 
be used to obtain the subject study identification number for each subject with a signed 
ICF.
12-week, Double-blind Treatment Period
Based on a randomization scheme, eligible 
subjects will 
be allocated in a 1:1:1 ratio at randomization to 1 of the following 3 treatment groups:

Brexpiprazole 1 mg/day

Brexpiprazole 2 mg/day

Placebo
 
 
 
 
Subjects will follow a titration schedule, depending upon their assigned treatment group, 
to gradually increase their dose to their assigned target dose. 
Subjects unable to tolerate their assigned dose of brexpiprazole (or matching placebo) 
will be withdrawn from the trial. Down-titration is not allowed at any time during the 
study. If a subject is withdrawn, every effort will be made to complete all of the Week 
12/Early Termination (ET) evaluations prior to administering any additional medications 
for the treatment of agitation or other prohibited medications. 
Subjects will be evaluated at Baseline, Day 3, and Weeks 2, 4, 6, 8, 10, and 12 during the 
double-blind treatment period. 
All attempts should be made to maintain the subjects’ normal routine with regard to 
physician appointments. Individual circumstances that fall outside this general convention 
should be discussed with the medical monitor in order to determine appropriateness to

proceed. In addition, the subject’s identified caregiver will be contacted by telephone at 
Weeks 3, 5, and 7 to assess compliance with IMP, confirm any changes to concomitant 
medications, and assure the subject’s well-being. Trial-related efficacy and safety 
assessments will be performed as outlined in the study protocol.
Follow-up Period
All subjects, whether they complete the trial or are withdrawn prematurely for any reason, 
will be followed up for a safety evaluation 30 (+ 2) days after the last dose of the IMP 
during a clinic visit at either the investigator’s site or residential facility, if applicable.  If 
a clinic visit is not possible, the subject should be assessed by telephone contact with the 
subject and a caregiver. For all subjects who terminate early from the trial, all attempts 
will be made to collect mortality data by telephone contact with the subject’s caregiver at 
Week 16.
Subjects who complete both the 12-week double-blind treatment period and the 30-day 
safety follow-up visit are eligible to enroll into Trial 331-13-211, which is a 2-month, 
observational, rollover trial to evaluate the safety of subjects with agitation associated 
with Alzheimer's disease who previously participated in Trial 331-12-283. For those 
subjects who plan to enroll into Trial 331-13-211, the 30-day safety follow-up visit for 
Trial 331-12-283 will occur as a clinic visit at either the investigator’s site or residential 
facility, if applicable.
4
Sample Size and Power Justification
The sample size was calculated based on the treatment effect of 6.5 points with a standard 
deviation (SD) of 16.5 in the change from baseline (Day 0 visit) to the end of the 
double-blind treatment period (Week 12 visit) in the CMAI total score, to achieve 85% 
power at a 2-sided alpha level of 0.05.  This results in 117 subjects in each of the groups 
(i.e., brexpiprazole 1 mg/day, brexpiprazole 2 mg/day, and placebo).  After allowance of 
10% non-evaluable subjects, the total number of subjects to be randomized is 132 per 
treatment arm.  The sample size was estimated based on a 1:1:1 randomization ratio 
(brexpiprazole 1 mg/day, brexpiprazole 2 mg/day, placebo).  
 
 
 
 the total number of subjects to be randomized 
will be approximately 420

Data Sets for Analysis and Missing Data
5.1
Data Sets for analysis
The following analysis samples are defined for this trial:
Randomized Sample:  consists of all subjects who were randomized into this trial. 
Subjects are considered randomized when they are assigned a treatment number by IVRS 
at the end of Screening Period. A subject receiving trial treatment outside of the IVRS 
will not be considered randomized, but safety will be reported.
Safety Sample:  consists of all subjects who were administered at least one dose of IMP.  
Subjects will be excluded from this population only if there is documented evidence (ie, 
drug dispensed = drug returned or no trial drug dispensed) that the subject did not take 
trial drug. If a subject is dispensed trial medication and is lost to follow up, he/she will be 
considered exposed.
Efficacy Sample:  The intent-to-treat (ITT) population consists of all subjects in the 
randomized sample, who took at least 1 dose of IMP (excluding subjects randomized to 
brexpiprazole 0.5 mg/day) and have a baseline and at least one postbaseline evaluation 
for the CMAI total score.
 
 
 
 
 
 
The core dataset for all efficacy analyses is based on the modified ITT population, which 
is defined in the efficacy sample above.  However, as described below, in order to handle 
missing data and restrictions imposed by different types of analyses (eg, change from 
baseline analysis), other datasets derived from the ITT population will be used for the 
efficacy analyses.

5.2
Handling of Missing Data
The CMAI is utilized as the primary efficacy assessment of a subject’s level of agitated 
behaviors.  The CMAI consists of 29 items all rated on a 1 to 7 scale with 1 being the 
“best” rating and 7 being the “worst” rating. The CMAI Total Score is the sum of ratings 
for all 29 items. The possible total scores are from 29 to 203. The CMAI Total Score will 
be unevaluable if less than 24 of the 29 items are recorded. If 24 to 28 of the 29 items are 
recorded, the total score will be the mean of the recorded items multiplied by 29 and then 
rounded to the first decimal place.
 
 
 
 
 
The primary efficacy variable is the change from baseline to Week 12 in the CMAI total 
score. 
In general, missing data will be handled by analysis of Mixed effect Model Repeat 
Measurement (MMRM) methodology based on observed-case (OC) data from protocol-
specified visits in the ITT population under the assumption of missing at random (MAR).
The OC dataset consists of actual observations recorded at each visit during the double-
blind acute treatment phase, and no missing data will be imputed.

Study Conduct
6.1
Subject Disposition and Reasons for Discontinuations
Subject disposition is summarized for the randomized sample. Disposition is summarized 
by treatment group and by subgroup of gender, age (<65; >=65 and <75; or >=75), race, 
and region (North America or Other). 
Reasons for discontinuation will be summarized for the randomized sample by treatment 
group and by subgroup of gender, age, race, and region.   
6.2
Treatment Compliance
Based on the Study Medication panel of the CRF, compliance in taking study medication 
is calculated by dividing the number of tablets taken by the total number of tablets the 
subjects were scheduled to take during the study period. For lost-to-follow up subjects, 
last study medication end date record will be used as the treatment end date.  
6.3
Protocol Deviation
Protocol deviations are summarized by center and type of deviation for randomized 
subjects by treatment group. A listing of protocol deviations will also be generated.
7
Baseline Characteristics
7.1
Baseline Definition 
For analyses of the double blind treatment period data, the baseline is the Baseline
measurement (expected to be at Day 0). Baseline measurement is defined as the last 
available measurement prior to the start of double-blind study medication.
7.2
Demographic Characteristics
Baseline demographic characteristics including age, gender, race, ethnicity, height, 
weight, waist circumference, and body mass index (BMI) will be tabulated by treatment 
group for all randomized subjects. Additional summaries by the following subgroups will 
be also generated: by gender, by age group (<65; >=65 and <75; or >=75), by race, and by 
region (North America or Other). 
Mean, range and standard deviation will be used to describe continuous variables such as 
age. Frequency distributions will be tabulated for categorical variables such as race.

Disease History
A summary of medical, psychiatric, neurological (excluding Alzheimer’s), and 
Alzheimer’s disease history will be presented for the Randomized Sample (by treatment 
group and overall).
7.4
Baseline Disease Characteristics
For the Randomized Sample, baseline and baseline disease characteristics will be 
summarized by treatment group and overall. The following baseline characteristics will 
be summarized at baseline: number (%) of institutionalized / non institutionalized 
subjects; CMAI total score; 
 
 CGI-S score, NPI total 
score; NPI-AA item score; MMSE score; 
 
 
Number of subjects with presence of psychotic symptoms will be summarized at baseline 
using NPI Delusion and Hallucination score. The counts will be provided for the 
following categories:  NPI item score >=4, >=5, >=6 on either hallucination or delusion 
score.
All patients randomized under original protocol, amendment 1, and amendment 2 is 
assumed to be institutionalized and will be included in institutionalized subgroup. 
8
Efficacy Analysis
All efficacy analyses pertaining to the double blind treatment period will be performed on 
the Efficacy Sample, and subjects will be included in the treatment group as randomized. 
 
Statistical comparisons are based on 2-sided, 0.05 significance levels.
NPI endpoints are collected using NPI-NH for institutionalized subjects and NPI/NPI-NH 
for non-institutionalized subjects. Since each score derivation of the NPI items is based 
on the frequency and severity scores only, no distinction will be made due to the 
instrument used. All analysis of NPI based endpoints will be based on totality of data, 
unless specified otherwise.

8.1
Primary Efficacy Endpoint
The primary efficacy endpoint is the change from the baseline (Day 0 visit) to the end of 
the double blind treatment period (Week 12 visit) in CMAI Total Score.  
8.1.1 Primary Efficacy Analysis
The primary endpoint will be analyzed using a mixed-effect model repeated measure 
(MMRM) model.  The primary efficacy outcome measure is the mean change from 
baseline (Day 0 visit) to the end of the double-blind treatment period (Week 12 visit) in 
the CMAI total score.  The primary statistical comparisons of interest are brexpiprazole 
2 mg/day versus placebo and brexpiprazole 1 mg/day versus placebo.  The null 
hypotheses of these comparisons are that there is no difference between the brexpiprazole 
treatment groups and placebo in change from baseline to endpoint in CMAI total score.  
To protect the experiment-wise 2-sided alpha level at 0.05 when making 2 comparisons 
of brexpiprazole doses versus placebo, the statistical testing will be carried out using a 
hierarchical testing procedure in the order of 1) comparison of 2 mg/day brexpiprazole 
versus placebo and 2) comparison of 1 mg/day brexpiprazole versus placebo.  Thus, if the 
test yields a statistically significant result at 0.05 (2-sided) for the comparison of 
2 mg/day brexpiprazole versus placebo, then the comparison of 1 mg/day brexpiprazole 
versus placebo will be tested at an alpha level of 0.05 (2-sided).
The primary analysis will be performed on the Efficacy Sample which includes all 
randomized subjects who took at least one dose of IMP in the double blind treatment 
period and who have both a baseline and at least one post-randomization CMAI Total 
Score during the double blind treatment period. The primary efficacy analysis will be 
performed by fitting a MMRM analysis with an unstructured (UN) variance covariance 
structure in which the change from the baseline in CMAI Total Score (Week 2, 4, 6, 8, 
10, 12) will be the dependent variable based on the OC data set.  The model will include 
fixed class-effect terms for treatment (1 mg/day, 2 mg/day, and placebo), trial center, visit 
week, and an interaction term of treatment by visit week and include the interaction term 
of baseline values of CMAI Total Score by visit week as covariates. The primary 
comparison between a brexpiprazole and the placebo arm at Week 12 will be estimated as 
the difference between Least Squares (LS) means from the interaction term of treatment 
by visit week utilizing the computing software SAS procedure PROC MIXED.

Key Secondary Analysis 
The key secondary efficacy variable is the change from baseline to endpoint in the CGI-S 
score, as related to agitation. It will be analyzed by the same statistical methodology 
specified for the analysis of the primary efficacy variable, based on the Efficacy Sample.  
In order to control the overall type I error rate for this key secondary efficacy analysis, a 
hierarchical testing procedure will be used so that the overall experiment-wise type I error 
rate is maintained at 0.05.  Thus, if the primary efficacy analysis for the CMAI total score 
yields a statistically significant result at 0.05 (2-sided) for both of the comparisons of 
brexpiprazole 1 mg/day and 2 mg/day versus placebo, then the corresponding comparison 
for this key secondary efficacy variable (CGI-S score) will be tested at an alpha level of 
0.05 (2-sided) using another hierarchical testing procedure in the order of brexpiprazole 2 
mg/day versus placebo and brexpiprazole 1 mg/day versus placebo.  Thus, brexpiprazole 
1 mg/day versus placebo will be tested only if brexpiprazole 2 mg/day versus placebo 
reaches significance at 0.05 (2-sided) for this key secondary efficacy variable.

Actigraphy and eDiary Data
Since actigraphy and eDiary are tools to assist the CST in monitoring CMAI rater 
training, actigraphy and eDiary information will not be made available to site personnel, 
will not be included in the clinical database, and will not be statistically analyzed.

Safety Analysis
Standard safety variables to be analyzed include AEs, clinical laboratory tests, vital signs, 
ECGs, body weight, waist circumference and physical examination.  In addition, data 
from the following safety scales will be evaluated:  MMSE score, 
 
 
 
  Prospectively defined criteria will be used to identify potentially 
clinically relevant abnormal values for clinical laboratory tests, vital signs, ECGs, and 
body weight.
Safety analysis will be conducted based on the Safety Sample.  In general, baseline of a 
safety variable is defined as the last observation of the variable before taking the first 
dose of IMP, unless specified otherwise. 
9.1
Adverse Events 
All adverse events will be coded by primary system organ class (SOC) and Medical 
Dictionary for Regulatory Activities (MedDRA version 19.0 ) preferred term (PT).  AEs 
that are gender-specific, e.g., ovarian cancer, will have their incidence rates evaluated for 
the specific gender. The incidence of the following events will be summarized by 
treatment group:
a) Treatment-emergent AEs (TEAE) by SOC and PT
b) TEAEs at least 5% in the brexpiprazole group and twice greater than placebo
c) TEAEs at least 2% in the brexpiprazole group and greater than placebo

Concomitant Medications
Number and proportion of subjects taking concomitant medications prior to study 
therapy, during the double blind treatment period, and after study therapy are tabulated by 
drug classification using the WHO drug dictionary.
9.10 Extent of Exposure
The start date of double-blind study therapy - brexpiprazole or placebo - will be the first 
day of double-blind dosing. The number and percentage of subjects, who receive double-
blind study medication, will be presented by week and by treatment group. Each dosing 
week will be based on the actual week; i.e., Day 1-7 in Week 1, Day 8-14 in Week 2, etc. 
This summary will be performed on the Safety Sample. 
The number and percentage of completers will be presented by week and by treatment 
group.
The mean daily dosage will be summarized by week and treatment group using 
descriptive statistics. The mean daily dosage per subject per week will be determined for 
each week of the study. This will be calculated by dividing the sum of individual total 
doses by the number of days in the week interval. The summary will contain for each 
treatment group the number of subjects receiving double-blind study medication, and the 
mean and range of the mean daily dose for each week.
10 Conventions
10.1 Study Visit Windows
Study visit windows will be used to map visits using study day intervals. This visit 
window convention applies to tables and listings for all efficacy and safety scales. This
derived study window variable will be named as WEEK and will be footnoted. In listings 
it will be listed along with the CRF study visit.
Table below shows classifications for study day intervals in the double-blind period. The 
variable “target day” is defined using the number of days since the start of double-blind 
dosing. The first day of double-blind dosing is defined as “Day 1”. If more than one 
observation falls within a particular study day interval, then the last observation within 
that interval is used.

10.3 Scales: Rules for Scoring and Handling of Missing Data
10.3.1 Cohen-Mansfield Agitation Inventory (CMAI)
The CMAI consists of 29 items all rated on a 1 to 7 scale with 1 being the “best” rating
and 7 being the “worst” rating. The CMAI Total Score is the sum of ratings for all 29 
items. The possible total scores are from 29 to 203. The CMAI Total Score will be 
unevaluable if less than 24 of the 29 items are recorded. If 24 to 28 of the 29 items are 
recorded, the total score will be the mean of the recorded items multiplied by 29 and then 
rounded to the first decimal place.
 
 
 
 
 
 
 
.
10.3.2 Clinical Global Impression-Severity of Illness Scale (CGI-S)
The severity of agitation for each subject will be rated using the CGI-S.  To perform this 
assessment, the investigator (or designee) will answer the following question: 
“Considering your total clinical experience with this particular population, how mentally 
ill (as related to agitation) is the subject at this time?”  Response choices are 0 = not 
assessed; 1 = normal, not at all ill; 2 = borderline mentally ill; 3 = mildly ill; 
4 = moderately ill; 5 = markedly ill; 6 = severely ill; and 7 = among the most extremely ill 
subjects. The score 0 (= not assessed) will be set to missing. The CGI-S is therefore a 7-
point scale from 1 through 7.

10.3.5 Neuro-psychiatric Inventory
The NPI consists of 12 items. For each item there is a screening question to determine if 
the behavioral change is present (rated 1) or absent (rated 0). For each item there are three 
scores: frequency, severity, and caregiver distress (NPI/NPI-NH) or occupational 
disruptiveness (NPI-NH). Frequency is rated on a 1 to 4 scale, severity is rated on a 1 to 3 
scale and the caregiver distress is rated on a 0 to 5 scale. The individual item score is 
calculated as presence x frequency x severity and has a range from 0 to 12. If presence is 
zero, the individual item score and caregiver distress score will be set to zero. For all 
items, low scores are ’better’ than high scores. 
The NPI Total Score is calculated by adding the individual item scores of the 12 items
together. The possible total scores are from 0 to 144. The NPI Total Score will be

Association (NINCDS-ADRDA)
The NINCDS-ADRDA, which has shown good reliability and validity, provides criteria 
for the possible and probable diagnosis of Alzheimer’s disease. These criteria require that 
cognitive impairment and a suspected dementia syndrome be confirmed by 
neuropsychological testing for a clinical diagnosis of Alzheimer’s disease.  The NINCDS-
ADRDA criteria specify 8 cognitive domains that may be impaired in Alzheimer’s 
disease:  memory, language, perceptual skills, attention, constructive abilities, orientation, 
problem solving and functional abilities.
10.3.10 Hachinski Ischemic Scale (Rosen Modification)
The Rosen-modified Hachinski Ischemic Scale assesses whether a subject’s dementia is 
likely due to vascular causes by the response to 8 questions:  abrupt onset, stepwise 
deterioration, somatic complaints, emotional incontinence, history of hypertension, 
history of stroke, focal neurologic signs, and focal neurologic symptoms.  The Rosen 
modified Hachinski Ischemic Scale will be completed to assess eligibility for the trial by 
the same neurologist who performs the neurological examination.

10.3.15 Mini-Mental State Examination (MMSE)
The MMSE is a brief practical test for assessing cognitive dysfunction. The test consists 
of 5 sections (orientation, registration, attention and calculation, recall, and language) and 
has a total possible score of 30.  The MMSE is used for screening subjects and is also to
be completed at Week 12/ET. 
The MMSE is a 19 item scale. Items 1 to 10, 15, and 17 to 19 are rated on a scale from 0
to 1, item 14 is rated on a 0 to 2 scale, items 11, 13 and 16 are rated on a scale from 0 to 3, 
and Item 12 is rated on a scale from 0 to 5. Low scores are the worst, high scores are the
best. The MMSE Total Score is calculated by adding the individual item scores. The
possible range for the MMSE Total Score is from 0 to 30. If the maximum total of the

missing items could contribute more than 6 points to the total score then the total score
will be set to missing. Otherwise a mean non-missing items score will be calculated by
summing the non-missing items and dividing them by the maximum score possible from
the non-missing items. For missing items with possible scores from 0 to 1, the mean score 
will be imputed for each missing item. If item 14 is missing, two times this mean will be 
imputed for item 14. If items 11, 13, or 16 are missing three times this mean for will be 
imputed each missing item. If item 12 is missing 5 times then this mean will be imputed 
for item 12. After all by-item imputation has been done, the individual item scores will be 
added and this sum will be rounded to the first decimal place to arrive at an imputed total 
score. In other terms, the MMSE Total Score is simply the mean non-missing items score 
multiplied by 30, and then rounded to the first decimal place.
