and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria 
for bipolar I disorder without psychotic features confirmed by the 
administration of the Mini International Neuropsychiatric Interview (MINI), 
with a current major depressive episode of at least 4 weeks and not exceeding 
12 months in duration, a minimum score of 20 on the 17-item Hamilton 
Depression Rating Scale (HAMD-17), a minimum score of 2 on item 1 of the

Statistical Methods
The primary efficacy parameter will be the change from baseline to Week 6 
in MADRS total score. The primary analysis will be performed using a 
mixed-effects model for repeated measures (MMRM) with treatment group, 
study center, visit, and treatment group–by-visit interaction as fixed effects 
and the baseline value and baseline by-visit interaction as covariates. An 
unstructured covariance matrix will be used to model the covariance of 
within-patient scores. 
The secondary efficacy parameter will be the change from baseline to Week 6 
in CGI-S score. The secondary efficacy parameter will be analyzed using an 
MMRM as used for the primary analysis.
Matched parallel gatekeeping procedure will be used to control the overall 
type I error rate for multiple comparisons of the 2 cariprazine dose groups 
(1.5 mg/day or 3.0 mg/day) with placebo at Week 6 for the primary and 
secondary efficacy parameters. Statistical significance will be determined by 
comparing the adjusted p-values to α = 0.050.

INTRODUCTION
Bipolar disorder is a complex, chronic illness causing dramatic mood swings and unusual 
shifts in energy and behavior, ultimately resulting in functional impairments. It manifests 
itself as alterations in mood and energy from euphoria and excitability (mania or 
hypomania) to depression and psychomotor retardation (Goodwin and Jamison, 1990) 
and is associated with significant morbidity and mortality. Bipolar disorder in the 
United States affects 5.7 million adults or about 2.6% of the population 18 years and 
older in any given year (Kessler et al, 2005) and has a considerable economic effect on 
our society (Wyatt and Henter, 1995). In the year 2000, this disorder ranked as the 
seventh leading cause of worldwide nonfatal disease burden (World Health Organization, 
2001). Suicide rates within this population are among the highest of all psychiatric 
illnesses (Muller-Oerlinghausen et al, 2002).
The depressive phase of bipolar disorder causes significantly more morbidity and 
mortality than the manic or hypomanic phase. Patients with bipolar disorder experience 
depressive symptoms much more frequently than manic or hypomanic symptoms 
(Hlastala et al, 1997; Judd et al, 2002, 2003; Keller et al, 1986; Post, 2005; Post et al, 
2003). In addition, compared with bipolar mania, bipolar depression is associated with an 
increased risk of suicide and psychosocial impairment (Altshuler et al, 2002; Calabrese 
et al, 2003, 2004; Dilsaver et al, 1997; Leverich et al, 2003; MacQueen et al, 2001).
Although there is a substantial burden associated with bipolar depression, the treatment 
of this phase of bipolar disorder has not been as widely studied as the treatment of bipolar 
mania, and pharmacotherapeutic options are limited. At present, only Seroquel 
(quetiapine), Seroquel XR (quetiapine XR), Symbyax (olanzapine and fluoxetine), and 
Latuda (lurasidone HCl) are approved by the FDA for the treatment of patients with 
bipolar depression. Other common pharmacotherapies include lithium, anticonvulsants 
(eg, valproate, lamotrigine), antidepressants, atypical antipsychotics, or combinations of 
these.
Treatment needs are not completely met by the currently available therapies; and only a 
low percentage of patients persistently benefit from them. A significant percentage of 
patients do not fully respond to the currently available treatments and continue to 
experience subthreshold symptoms and even relapse. Side effects commonly associated 
with the currently available treatments for bipolar depression include tremors, 
psychomotor slowing, cognitive impairment, exacerbation of agitation, nephrotoxicity, 
altered thyroid function, and sexual dysfunction. Atypical antipsychotics in particular 
have been associated with an increased risk of metabolic side effects, including body 
weight gain, dyslipidemia, glucose intolerance, and type 2 diabetes. The use of 
antidepressants has been shown to increase the risk of switching to the manic phase. 
More effective therapies with improved side effect profiles are still needed to enhance 
outcomes in these patients without the possibility of inducing mania or rapid cycling.

Dysfunction in dopamine (DA) neurotransmission has been implicated in the 
pathophysiology of bipolar disorder. Several lines of evidence suggest that the manic 
phase is associated with increased DA neurotransmission and the depressive phase with 
decreased DA neurotransmission. It has been hypothesized that the cyclical nature of 
bipolar disorder is due to alterations between these hyper- and hypodopaminergic states
(Berk et al, 2007). The contributions of individual D2-like receptor subtypes (D2, D3, D4) 
to bipolar disorder are not fully established. However, there is increasing evidence that 
D3 receptors may play an important role in depression. Evidence for this has been derived 
mainly from studies in mice with a targeted disruption of D3 receptors (D3(-/-) mice). 
These animals are more resistant to stressful procedures, display anxiolytic-like behavior,
and are more sensitive to antidepressants in behavioral models compared with the 
wild-type littermates (Leggio et al, 2008; Steiner et al, 1997). A compound with a 
“DA system stabilizing” effect and with preferable D3 receptor functional antagonist 
properties may prove to be most beneficial for the treatment of all the phases of bipolar 
disorder including bipolar depression. RGH-188 (cariprazine) exhibits these 
characteristics.
Cariprazine is an orally active and potent dopamine D3-preferring D3/D2 receptor partial 
agonist discovered by Gedeon Richter Plc., Budapest, Hungary, and currently in 
development by Forest Laboratories, LLC (an Allergan Affiliate), and Gedeon Richter 
Plc, for the treatment of schizophrenia, acute bipolar mania, bipolar depression, and as 
adjunctive treatment for major depressive disorder. In September 2015, cariprazine 
(VRAYLAR™) was approved in the United States for the treatment of schizophrenia, at 
doses of 1.5 to 6 mg/day, and for the acute treatment of manic or mixed episodes 
associated with bipolar I disorder, at doses of 3 to 6 mg/day. 
The chemical name of the hydrochloride salt of cariprazine is trans-N-{4-[2-[4-
(2,3-dichlorophenyl)-piperazine-1-yl]-ethyl]-cyclohexyl}-N’,N’-dimethylurea 
hydrochloride. Its molecular formula is C21H32Cl2N4O HCl; its molecular weight is 
463.87. Two main metabolites, desmethyl and didesmethyl cariprazine, have been 
identified. The receptor binding profile of both these metabolites is similar to that of the 
parent compound.
A unique feature of cariprazine is that it binds with significantly higher affinity to D3 than 
to D2 receptors. Its affinity for D3 receptors is approximately 1 order of magnitude greater 
than that for D2 receptors. Similar to aripiprazole, but unlike other atypical 
antipsychotics, cariprazine acts as a “DA system stabilizer.” Cariprazine displays partial 
agonist as well as antagonist activity on biosynthesis- (and release-) modulating 
presynaptic D2 receptors and has preferential dopaminergic actions in the limbic regions. 
However, cariprazine is more potent than aripiprazole, and the degree of its apparent 
partial agonist activity is greater.

Cariprazine also has considerable affinity for, and is a partial agonist and antagonist at, 
the serotonin 5-HT1A and 5-HT2B receptors, respectively. Antidepressant-like and/or 
anxiolytic-like effects of cariprazine may also be mediated through these receptors. 
Cariprazine has low potency at other receptor sites, such as the 5-HT2C, histamine H1, and 
adrenergic receptor sites.
Cariprazine was evaluated in patients with bipolar depression in 2 multicenter, 
randomized, double-blind, placebo-controlled studies (Study RGH-MD-52 [2011] and 
Study RGH-MD-56 [2014]). 
Study RGH-MD-52 was 11 weeks in duration: a no-drug washout period of up to 1 week, 
8 weeks of double-blind treatment, and 2 weeks of safety follow-up with treatment as 
determined by the PI. This was a fixed-flexible dose study. A total of 227 Bipolar I and II
patients were randomized to 1 of 3 treatment groups and received at least 1 dose of the 
investigational product: placebo (n = 77), cariprazine low dose (0.25-0.75 mg/day, 
n = 75) and cariprazine high dose (1.5-3.0 mg/day, n = 75). The dose was fixed for first 
4 weeks of double-blind treatment; all patients received the lower of the dose range 
(1 capsule; placebo, cariprazine 0.25 mg/day, or cariprazine 1.5 mg/day). At the end of 
Week 4, the dose could be increased to 2 capsules if response was not adequate 
(< 40% reduction in Montgomery-Åsberg Depression Rating Scale [MADRS] score from 
baseline) and there were no significant tolerability issues as judged by the Investigator. 
Approximately 76% of the patients completed the study: 78% in the placebo group, 
84% in the cariprazine low-dose group, and 65% in the cariprazine high-dose group. 
More patients discontinued for adverse events (AEs) in the cariprazine high-dose group 
(9.3%) than in the placebo group (2.6%) and cariprazine low-dose group (4.0%). The 
average patient age was 39 years, and approximately 64% were female. The 3 treatment 
groups were balanced with respect to demographics and baseline characteristics. For the 
primary efficacy parameter, the change from baseline to the end of Week 8 in the 
MADRS total score using mixed-effects model for repeated measures (MMRM), the 
overall p-value was not statistically significant. Numerical improvement was seen in the 
cariprazine high-dose group relative to the placebo group up to end of week 6. Similar 
results were seen for other efficacy parameters. SAEs were reported in 6 patients 
(2 patients in the placebo group, 2 patients in the cariprazine low-dose group, and 
2 patients in the cariprazine high-dose group). Treatment-emergent adverse events 
(TEAEs) reported in at least 10% of patients in any treatment group included insomnia, 
akathisia, headache, dry mouth, nausea, upper respiratory tract infection and diarrhea. Of 
these, insomnia, akathisia, dry mouth, nausea and diarrhea were reported more frequently 
in the cariprazine-treated patients.

Study RGH-MD-56 was 11 weeks in duration and comprised up to 14 days of screening 
followed by 8 weeks of double-blind treatment and 1 week of safety follow-up. A total of 
584 bipolar I patients were randomized to 1 of 4 treatment groups and 578 patients 
received at least 1 dose of the investigational product: placebo (n = 145), cariprazine 
0.75 mg/day (n = 141), cariprazine 1.5 mg/day (n = 146), cariprazine 3 mg/day (n = 146). 
Overall, 72.5% of the patients completed the study: 72.4% in the placebo group, 73.0% in 
the cariprazine 0.75 mg/day group, 80.1% in the cariprazine 1.5 mg/day group, and 
64.4% in the cariprazine 3 mg/day group. The average patient age was 42 years, and 
approximately 62% were female. For both the primary and secondary efficacy 
parameters, change from baseline in MADRS total score and Clinical Global 
Impressions-Severity (CGI-S) score at Week 6, statistically significant improvement was 
demonstrated for the cariprazine 1.5 mg dose relative to placebo. Nominally significant 
improvement was shown for cariprazine 3 mg, which did not remain statistically 
significant after adjusting for multiplicity. No statistically significant treatment effect was 
shown for the 0.75 mg dose at Week 6. A post-hoc analysis of patients who completed 
the full 8 weeks of treatment (completer population) in Study RGH-MD-56 demonstrated 
similar reductions from baseline relative to placebo in MADRS total score for the 
cariprazine 1.5 and 3 mg/day groups at Week 6 and Week 8. Cariprazine was generally 
well-tolerated. No deaths were reported during the study. Serious adverse events were 
reported for 5 patients (3.4%) in the placebo group, 1 patient (0.7%) in the cariprazine 
0.75 mg group, and 2 patients (1.4%) each in the cariprazine 1.5 mg and 3 mg treatment 
groups. Adverse events that led to discontinuation were reported in similar proportions of 
patients across the placebo (10.3%) and cariprazine (8.2%-11.6%) treatment groups. The 
most common AEs that led to discontinuation were akathisia, agitation, anxiety, and 
depression. Overall, TEAEs were reported for 55% of patients in the placebo treatment 
group and 57%-62% of patients in the cariprazine treatment groups. Akathisia and 
irritability were the only TEAEs reported for ≥ 5% of patients in any cariprazine 
treatment group and at an incidence at least twice that of the placebo group. 
Based upon these data, the current study is designed to prospectively confirm the efficacy 
of a fixed-dose regimen of cariprazine 1.5 mg/day or 3 mg/day compared to placebo for 
treatment of the depressive episode in patients with bipolar I disorder. The safety and 
tolerability of the fixed-dose regimens will be evaluated. 
A description of the chemistry, pharmacology, toxicology, pharmacokinetics, and clinical 
results of cariprazine is provided in the Investigator’s Brochure (RGH-188 [cariprazine], 
2015).

INVESTIGATIONAL PLAN
9.1
OVERALL STUDY DESIGN AND PLAN: DESCRIPTION
This clinical study will be a multicenter, randomized, double-blind, placebo-controlled, 
parallel-group, fixed-dose study in adult patients with a Diagnostic and Statistical 
Manual of Mental Disorders, Fifth Edition (DSM-5; American Psychiatric Association, 
2013) diagnosis of Bipolar I disorder who are currently experiencing a major depressive 
episode.
The study will be conducted in outpatients (i.e., non-hospitalized) and will consist of 
approximately 7 to 14 days of screening and washout followed by 6 weeks of 
double-blind treatment and a 1-week safety follow-up period. At the end of the screening
period, patients meeting the eligibility criteria for this study will be randomized (1:1:1) to 
1 of 3 treatment groups (placebo, cariprazine 1.5 mg/day, cariprazine 3 mg/day). The 
study is designed to enroll outpatients, but as per local clinical practice, patients may be 
hospitalized for up to 7 days during the screening period or during the first week of 
treatment with double-blind investigational product. Further need for hospitalization will 
require consultation with the Study Physician. A total of 480 patients are planned to be 
randomized in this study.
Patients who complete 6 weeks of double-blind treatment or who prematurely 
discontinue before completing 6 weeks of double-blind treatment will be followed for 
1 more week (safety follow-up period). During the safety follow-up period, patients may 
be started on a standard treatment as determined by the PI. No investigational product 
will be administered during the safety follow-up period.

DISCUSSION OF STUDY DESIGN, INCLUDING THE CHOICE 
OF CONTROL GROUPS
The double-blind design was adopted to minimize systematic bias resulting from the 
Investigator or the patient knowing the treatment being administered. Randomization is 
expected to minimize patient selection bias and increase baseline comparability among 
the treatment groups. The doses of cariprazine under study were chosen on the basis of 
experience from the RGH-MD-52 and RGH-MD-56 studies (see Section 7.0), as well as 
experience in the cariprazine development program in healthy volunteers and patients 
with other indications and other atypical antipsychotics for the treatment of bipolar 
depression. The use of a placebo control is critical to the study to allow discrimination of 
patient outcomes caused by the individual dose levels of cariprazine from outcomes 
caused by other factors (e.g., the observer or patient expectations, the natural progression 
of the disease, the conditions of being in a study).
No double-blind down-taper has been included as cessation of cariprazine at doses 
comparable to those under study has not given rise to appreciable discontinuation 
symptoms.

9.3.3
Removal of Patients from Therapy or Assessment
A premature discontinuation will occur when a patient who signed the ICF ceases 
participation in the study, regardless of circumstances, before the completion of the 
protocol. Patients can be prematurely discontinued from the study for one of the 
following reasons:

Screen Failure (Failure to meet inclusion/exclusion criteria)

Withdrawal of consent

Adverse event

Lack of Efficacy

Protocol violation

Non-compliance with Study Drug

Lost to follow-up

Study terminated by Sponsor

Site terminated by Sponsor

Other
A patient completing Visits 1 through 6 will be considered a completer. All randomized
patients who prematurely discontinue from the study, regardless of the cause, should be
seen for a final assessment at an early termination (ET) visit. A final assessment will be 
defined as completion of the evaluations scheduled for Visit 6/ET). All investigational 
products dispensed at earlier visits that had not been previously collected should be 
collected at the final visit. Patients refusing to come in for a final visit must be requested 
in writing, with a registered letter, to come in for an ET visit and to return any unused 
investigational product. A copy of the letter, together with the source documentation, will 
be kept by the Investigator. The reasons for premature discontinuation from the study will 
be reflected on the study termination record of the eCRF.
Patients with Visit 6/ET more than 4 days after the last dose of double-blind 
investigational product will be administered safety assessments only.

TREATMENTS
9.4.1
Treatments Administered
Investigational product in the form of capsules packaged in blister packs will be provided 
by the Sponsor. No investigational product will be administered during the screening 
period or the safety follow-up period. For the 6-week double-blind treatment period, 
patients will be supplied with identically appearing capsules of either cariprazine or 
placebo.
9.4.2
Identity of Investigational Product(s)
Investigational product will be supplied in blister packs containing 10 capsules and will 
be labeled with the protocol number, the visit number/space to write visit number, storage 
information, warning language (viz, “Caution: New Drug—Limited by Federal Law to 
Investigational Use”), and instructions to take the capsules once daily as directed, and the 
medication identification number. Investigational product labels will be country specific. 
Immediately before dispensing the investigational product, the Investigator will write the 
patient’s initials, site number, and date on the label.
All investigational products will be provided by the Sponsor, or designees, to the study 
centers. Investigational product must be stored in an appropriate secure area (e.g., a 
locked cabinet in a locked room) at controlled room temperature 
 
, with excursions permitted between 
and must be 
protected from light, heat, and moisture.
The Investigator is responsible for recording the receipt and use of all investigational 
products supplied and for ensuring the supervision of the storage and allocation of these 
supplies. All unused investigational products must be returned; and, whenever 
investigational products are returned, unit counts must be performed. All investigational 
products must be accounted for. At the end of the study, or upon drug expiration, any 
unused investigational product must be returned to the Sponsor or Sponsor's designee.

Method of Assigning Patients to Treatment Groups
 
 
 
 
Forest Laboratories, LLC
Page 33 of 121
17 Feb 2016
Amended Protocol RGH-MD-53 Amendment 2

Each study center will be provided with investigational products. An interactive 
voice/interactive Web response system (IxRS) will be used during the study to monitor 
enrollment and medication allocation. If the patient meets the randomization criteria, the 
study center will contact the IxRS at end of Visit 2 to randomize the patient. IxRS will 
randomize the patient to the appropriate treatment arm (placebo, cariprazine 1.5 mg/day, 
or cariprazine 3.0 mg/day) and determine the investigational product number to be 
assigned to the patient based on the randomization.
9.4.4
Selection of Dosages in the Study
The doses of cariprazine selected for this study were based on the results from 
2 completed studies in patients with bipolar depression (RGH-MD-52 and RGH-MD-56), 
as well as experience in the cariprazine development program in healthy volunteers and 
patients with other indications and other atypical antipsychotics for the treatment of
bipolar depression. Study RGH-MD-52 indicated numerically better results for the 
high-dose cariprazine group (1.5-3.0 mg/day) relative to placebo up to end of Week 6. In 
the cariprazine low-dose group (0.25-0.75 mg/day), better efficacy was observed 
following a dose increase, and tolerability was not compromised. Thus, cariprazine 0.75, 
1.5, and 3.0 mg/day were selected for further evaluation in Study RGH-MD-56.
In Study RGH-MD-56, for both the primary and secondary efficacy parameters, change 
from baseline in MADRS total score and CGI-S score at Week 6, statistically significant 
improvement was demonstrated for the cariprazine 1.5 mg dose relative to placebo. 
Nominally significant improvement was shown for cariprazine 3 mg, which did not 
remain statistically significant after adjusting for multiplicity. No statistically significant 
treatment effect was shown for the 0.75 mg dose at Week 6. A post-hoc analysis of 
patients who completed the full 8 weeks of treatment (completer population) in 
Study RGH-MD-56 demonstrated similar reductions from baseline relative to placebo in 
MADRS total score for the cariprazine 1.5 and 3 mg/day groups at Week 6 and Week 8.
The primary efficacy results and the post-hoc completers analysis in Study RGH-MD-56 
led to the selection of the cariprazine 1.5 and 3 mg/day doses for further evaluation in this 
study. A dose higher than 3 mg/day was not chosen because of concerns related to the 
potential for higher extrapyramidal symptom rates with increasing cariprazine dose.
A fixed-dose regimen allows for unambiguous evaluation of safety and efficacy of 
individual doses.
9.4.5
Selection and Timing of Dose for Each Patient
All investigational products will be dispensed in blister packs. Each blister pack will 
contain 10 capsules arranged in 10 columns and 1 row, adequate for the 7 days of the 
week plus 3 extra days. The configuration of the blister packs is provided in 
Table 9.4.5–1.

Amended Protocol RGH-MD-53 Amendment 2

At Visit 2, patients who continue to meet all eligibility criteria will be assigned a 
randomization number and dispensed a corresponding blister pack of double-blind 
investigational product for the first week of double-blind treatment. Patients will be 
instructed to take 1 capsule daily, in order from left to right of the blister pack, beginning 
on the evening of Visit 2 or the morning after Visit 2
At Visit 3 (end of week 1 of double-blind treatment) patients will be dispensed 1 blister 
pack. At Visits 4 and 5 (end of week 2 and end of week 4 of double-blind treatment), 
patients will be dispensed 2 blister packs.
All patients randomized to cariprazine dose groups will receive cariprazine 1.5 mg/day 
for 2 weeks, from Day 1 through Day 14. For patients randomized to the cariprazine 
3.0 mg/day group, the dose will be increased to 3.0 mg/day on Day 15. 
Drug holidays (up to a maximum of 3 consecutive days) are allowed if there are 
tolerability problems at the discretion of the Investigator. Patients unable to tolerate the 
fixed dose of the investigational product or patients off drug for 4 or more consecutive 
days will be prematurely discontinued from the study.
All investigational products will be taken orally as a single daily dose at approximately 
the same time of day (morning or evening). The dosing time can be switched if there are 
tolerability problems. Any switch must allow at least 24 hours between 2 consecutive 
doses and must be documented in the eCRF.
At each visit, patients will be instructed to return all unused investigational product.

9.4.6
Blinding
The study will be conducted as a double-blind investigation. A list of patient 
randomization codes will be generated by the Sponsor’s Statistical Programming, and 
implemented by the IxRS vendor (an electronic version will be stored on a secure server). 
This list will identify each patient by randomization number and include the patient’s 
corresponding treatment assignment. 
9.4.7
Unblinding
Any unblinding at the study center level should be done only in an emergency that 
requires for the investigational product to be identified for the medical management of 
the patient. The Investigator has to notify the study physician immediately 
(see Appendix II) and a full written explanation must be provided if the blind is broken. 
Before the investigational product is unblinded, every attempt should be made to discuss 
the case with the Study Physician. Breaking the code at the study center will immediately 
disqualify the patient from further participation in the study.
Treatment codes may be broken by the Sponsor’s Global Drug Safety department, for 
regulatory reporting purposes. In such cases, the study staff will be kept blinded and the 
patient will not need to be disqualified from the study.
In an emergency, the Investigator can obtain the treatment assignment of any patient at 
his or her study site through the IxRS. In an emergency, the Investigator will access the 
IxRS to break the blind.
The unblinding of bioanalytical representatives is to be carried out in a secure manner 
following the Sponsor’s standard operating procedures. Extreme care and diligence will 
be taken to ensure no other individuals outside the bioanalytical team will be unblinded.

Prior and Concomitant Therapy
A complete list of drugs that are allowed and not allowed as concomitant medications for 
either episodic or long-term use is provided in Appendix III. Throughout the duration of 
this study, additional psychotropic medications, including psychostimulants, are not 
allowed, with some notable exceptions listed below. Psychotropic medications include 
the following: antipsychotics, antidepressants (including monoamine oxidase-B 
inhibitors), stimulants, anticonvulsants/mood stabilizers, sedatives/hypnotics/anxiolytics, 
dopamine releasing drugs or dopamine agonists, and psychotropic drugs not otherwise 
specified (including herbal products).
Patients will be asked to abstain from drinking alcohol during the study. Patients who 
have been taking stable doses of benzodiazepines (up to 2 mg/day) for at least 1 month
before randomization can continue use. Medically appropriate episodic use (up to 3 days)
of narcotic analgesics for acute medical indications (i.e., tooth extraction) is allowed 
during the study.
Medication history, including the use of psychotropic medication and of any other 
medication, will be recorded at Visit 1 (Screening). Thereafter, any changes in 
concomitant medications or new medications added will be recorded in the eCRF.
For insomnia the following will be allowed. It should not be prescribed 
prophylactically.

Zolpidem (maximum of 10 mg/day)

Zolpidem extended release (maximum of 12.5 mg/day)

For EPSs or akathisia:
For EPSs or akathisia that emerge or worsen during the study, the following rescue 
medications will be allowed; however, each of the 3 EPS scales (Abnormal Involuntary 
Movement Scale [AIMS], Barnes Akathisia Rating Scale [BARS], and Simpson Angus 
Scale [SAS]) should first be performed (unless a medical urgency [eg, dystonia, severe 
akathisia, etc] requires otherwise) to support the decision to administer the medications:

Benztropine (up to 4 mg/day orally or up to 2 mg/day if given parenterally) or 
equivalent (eg, trihexyphenidyl up to 6 mg/day in divided doses)

Diphenhydramine (up to 50 mg/day) for EPS

Propranolol for the treatment of akathisia. Daily dose of propranolol depends on heart 
rate and BP (up to 160 mg/day)
The medication listed above should not be used prophylactically. The need for continued 
use of these medications should be regularly assessed by the PI and documented 
appropriately. The EPSs must be documented on the AE page of the eCRF, and the 
medication on the concomitant medications page of the eCRF.
Injectable agents are not allowed, except for the treatment of an acute dystonic reaction if 
deemed necessary.
Rescue medications for agitation, restlessness, and hostility:
Episodic use of lorazepam up to 2 mg/day (or equivalent) and for up to 3 consecutive 
days at a time is allowed for agitation, restlessness, and hostility.
The agitation, restlessness, or hostility must be documented on the AE and/or the medical 
history page of the eCRF. The medication use must be documented on the rescue 
medication page of the eCRF. Efficacy assessments should not be performed within 
8 hours of administration of lorazepam or equivalent benzodiazepine or within 24 hours 
of administration of diazepam.
9.4.9
Monitoring Treatment Compliance
Investigational product compliance will be monitored by counting the number of capsules 
dispensed and the number returned by the patient. Before new investigational product is 
dispensed at any visit, every effort will be made to collect all unused investigational 
product. If a patient demonstrates poor compliance at any time during the study (< 80% 
or > 120% measured by pill counts), then they should be discontinued from the study.

EFFICACY AND SAFETY VARIABLES
9.5.1
Diagnostic and Efficacy Assessments
9.5.1.1
Diagnostic Assessment
Mini International Neuropsychiatric Interview (Version 7.0.0, 01 Jan 2014)
The MINI (Version 7.0.0, 01 Jan 2014) is a clinician-rated diagnostic assessment that will 
be considered a source document in this study. The interview will be administered by the 
PI or Sub-Investigator who is a psychiatrist or a doctoral-level clinical psychologist or 
who has extensive professional training and experience in the diagnosis of mental illness.
9.5.1.2
Primary Efficacy Assessment
Montgomery-Åsberg Depression Rating Scale
The MADRS (Montgomery and Åsberg, 1979) is a 10-item, clinician-rated scale that 
evaluates the patient’s depressive symptomatology during the past week. Patients are 
rated on items assessing feelings of sadness, lassitude, pessimism, inner tension, 
suicidality, reduced sleep or appetite, difficulty in concentration, and lack of interest. 
Each item will be scored on a 7-point scale with a score of 0 reflecting no symptoms and 
a score of 6 reflecting symptoms of maximum severity. This scale will be administered 
by a trained rater with adequate experience in the assessment of the patient’s depressive 
symptomatology using the MADRS.
9.5.1.3
Secondary Efficacy Assessment
Clinical Global Impressions–Severity
The CGI-S (Guy, 1976) is a clinician-rated scale that measures the overall severity of a 
patient’s illness in comparison with the severity of other patients the physician has 
observed. The patient is rated on a scale from 1 to 7 with 1 indicating a “normal state” 
and 7 indicating “among the most extremely ill patients.” The CGI-S will be administered 
by the PI or a Sub-Investigator with extensive professional training and experience in 
assessing mental illness.

9.5.2.1
Adverse Events
An AE is any untoward medical occurrence in a patient or clinical investigation patient
administered a pharmaceutical product and which does not necessarily have to have a 
causal relationship with this treatment. An AE can therefore be any unfavorable and 
unintended sign (including an abnormal laboratory finding, for example), symptom, or 
disease temporally associated with the use of a medicinal product, whether or not 
considered related to the medicinal product (ICH-E2A).
 
Forest Laboratories, LLC
Page 40 of 121
17 Feb 2016
Amended Protocol RGH-MD-53 Amendment 2

For the purpose of the site’s data collection responsibilities, any untoward event that was 
reported from the time the patient signed the ICF until 30 days after the final 
protocol-defined study visit or, if the final visit does not occur, the last known dose of 
investigational product, is to be considered an AE.
Examples of AEs are as follows:

Changes in the general condition of the patient

Subjective symptoms offered by or elicited from the patient

Objective signs observed by the Investigator or other study site personnel

All diseases that occur after signing inform consent, including any change in severity 
or frequency of preexisting disease

All clinically relevant abnormalities in laboratory values or clinically relevant 
physical findings that occur during the study schedule
Please note medical procedures scheduled prior to consenting, but occurring during the 
study should not be captured as AEs, but should be listed in the medical history if related 
to a pre-existing condition.
9.5.2.2
Causality Assessment
For each AE, the Investigator must provide an assessment of causal relationship to the 
investigational product. The causality assessment must be recorded on the appropriate 
AE reporting page of the patient’s eCRF. Causal relationship must be assessed by 
answering the following question:
Is there a reasonable possibility the investigational product caused the event?
Yes:
There is evidence to suggest a causal relationship between the investigational 
product and AE; i.e.:
○
There is a reasonable temporal relationship between the investigational 
product and the event, and/or
○
The event is unlikely to be attributed to underlying/concurrent disease, other 
investigational products, or other factors, and/or
○
Positive dechallenge and/or rechallenge exist
 
Forest Laboratories, LLC
Page 41 of 121
17 Feb 2016
Amended Protocol RGH-MD-53 Amendment 2

No:
There is no evidence to suggest a causal relationship between the 
investigational product and AE, i.e.:
○
There is no reasonable temporal relationship between the investigational 
product and the event, or
○
The patient did not take the investigational product, or
○
The event is likely to be attributed to underlying/concurrent disease, other 
investigational products, or other factors, or
○
The event is commonly occurring in the (study) population independent of 
investigational product exposure
9.5.2.3
Severity Assessment
The Investigator will provide an assessment of the severity of each AE by recording a 
severity rating on the appropriate AE reporting page of the patient’s eCRF. Severity,
which is a description of the intensity of manifestation of the AE, is distinct from 
seriousness, which implies a patient outcome or AE-required treatment measure 
associated with a threat to life or functionality (Section 9.5.2.4). Severity will be assessed 
according to the following scale:
Mild:
A type of AE that is usually transient and may require only minimal 
treatment or therapeutic intervention. The event does not generally 
interfere with usual activities of daily living.
Moderate:
A type of AE that is usually alleviated with additional specific therapeutic 
intervention. The event interferes with usual activities of daily living, 
causing discomfort but poses no significant or permanent risk of harm to 
the research participant.
Severe:
A type of AE that interrupts usual activities of daily living, or significantly 
affects clinical status, or may require intensive therapeutic intervention.
9.5.2.4
Serious Adverse Events
An SAE is any untoward medical occurrence that at any dose:

Results in death

Is life threatening

Requires inpatient hospitalization or prolongation of existing hospitalization
 
Forest Laboratories, LLC
Page 42 of 121
17 Feb 2016
Amended Protocol RGH-MD-53 Amendment 2


Results in persistent or significant disability/incapacity, or

Is a congenital anomaly/birth defect
Important medical events that may not result in death, be life threatening, or require 
hospitalization may be considered serious when, based on appropriate medical judgment, 
they may jeopardize the patient or subject and may require medical or surgical 
intervention to prevent one of the outcomes listed in this definition. Examples of such 
medical events include allergic bronchospasm requiring intensive treatment in an 
emergency room or at home, blood dyscrasias or convulsions that do not result in patient
hospitalization, or the development of investigational product dependency or drug abuse.
Emergency room visits that do not result in hospitalization should be evaluated for one of 
the other serious outcomes to determine whether they qualify as SAEs.
Preplanned hospitalizations (e.g., elective procedures for preexisting conditions that did 
not worsen, such as cosmetic surgery and hysterectomy) or routine (i.e. required) 
country-specific hospitalization during washout are excluded from SAE reporting.
9.5.2.5
Reporting Adverse Events and Serious Adverse Events
At each visit, patients are to be queried regarding any AEs or SAEs that have occurred 
since the previous visit. Patients will be asked to volunteer information with a nonleading 
question such as, “How do you feel since your last visit?” Study site personnel will 
record all pertinent information in the patient’s eCRF. 
All AEs must be recorded on the appropriate AE reporting page of the patient’s eCRF
whether or not they are considered causally related to the investigational product.
For every AE, the Investigator must:

Provide an assessment of the seriousness of the event (i.e., is it an SAE?), as well as 
the severity and casual relationship

Document all actions taken with regard to the investigational product

Detail any other treatment measures taken for the AE

Document the outcome of the AE

Amended Protocol RGH-MD-53 Amendment 2

In addition, patients are to be reminded, as described in the ICF and in accordance with 
Section 9.5.2.1, to notify site personnel of any AEs occurring during the 30 day 
post-study period. Any AEs reported by the patient (or patient representative) during this 
period are to be recorded in original source documents. AEs are also to be recorded in the 
eCRF if at least one of the following conditions is met: 1) the event meets the criteria for 
an SAE (see Sections 9.5.2.4 and 9.5.2.6), and/or 2) the event is judged by the 
Investigator to be potentially causally related to investigational product.
Any AEs that are ongoing at the time of the final protocol-defined study visit will be 
followed until the condition returns to prestudy status, has resolved or stabilized, or can 
be explained as being unrelated to the investigational product. If a follow-up visit is 
deemed necessary for appropriate safety surveillance, it will take place within 30 days of 
the final protocol-defined study visit.
9.5.2.6
Immediate Reporting of Serious Adverse Events and Events of 
Special Interest
The Sponsor is required to inform worldwide regulatory authorities of SAEs and Ocular 
Events of Special Interest that meet specific criteria. Therefore, the Sponsor must be 
notified immediately regarding any SAE and Ocular Events of Special Interest that occur 
after informed consent is obtained.
The following serious and non-serious adverse events (ie, Ocular Events of Special 
Interest) require a 15-day alert report: 

cataract, lens, or lenticular abnormality or change, opacity, opacification or 
opalescence

blindness, night blindness, visual acuity or vision decrease, abnormality or change,
visual acuity test abnormality or change

retinal, macular, or optic nerve degeneration, abnormality or change; retinal pigment 
epithelium detachment, abnormality or change

color vision decrease, abnormality or change
Within 24 hours of learning of any AE that meets one of the criteria for an SAE, the 
study site personnel must report the event to the Sponsor’s Global Drug Safety 
department on the SAE Form for Clinical Trials.
Within 24 hours of learning of any non-serious Ocular Event of Special Interest, the 
study site personnel must report the event on the Ocular Event Reporting Form. Serious 
Ocular Events should be reported on the SAE Form for Clinical Trials.
 
Forest Laboratories, LLC

17 Feb 2016
Amended Protocol RGH-MD-53 Amendment 2

In addition to completing the appropriate form, the Sponsor’s Study Safety Physician
may also be notified by telephone.
If, during follow-up, any nonserious AE worsens and eventually meets the criteria for an 
SAE, that AE should be recorded as a new SAE.
The site must transmit the SAE Form for Clinical Trials or the Ocular Event of Special 
Interest form to the SAE fax number shown below. Even if an initial report is made by
telephone, the SAE Form for Clinical Trials or the Ocular Event of Special Interest form,
completed with all available details, must still be faxed within 24 hours of knowledge of 
the event at the study site.
Supplemental information should be submitted as soon as available and may include 
laboratory results, radiology reports, progress notes, hospital admission and emergency 
room notes, holding and observation notes, discharge summaries, autopsy reports, and 
death certificates.
The Investigator is expected to take all therapeutic measures necessary for resolution of 
the SAE. Any medications or procedures necessary for treatment of the SAE must be 
recorded on the appropriate pages of the patient’s eCRF. All SAEs and Ocular Events of 
Special Interest are to be followed by the study staff until resolution or until the SAE or 
Ocular Event of Special Interest is deemed stable. The Sponsor may contact the study 
site to solicit additional information or follow up on the event.
Fax the SAE Form for Clinical Trials to the Sponsor:

The Medical Emergency Phone number is provided in Regulatory Binder contact list. 
9.5.2.7
Reporting of Pregnancies Occurring During the Study
Study site personnel must report every pregnancy from the time the patient signs the ICF 
until 30 days after the last dose of investigational product. Within 24 hours of learning of 
the pregnancy, the study site personnel must report the event to the Sponsor’s Global 
Drug Safety department on the Clinical Trial Pregnancy Form and fax it to the 
SAE/Pregnancy fax number stated in Section 9.5.2.6, even if no AE has occurred.
Pregnancies in female partners of male patients occurring during the time frame 
described above must also be reported. 
 
Forest Laboratories, LLC

The pregnancy must be followed to term and the outcome reported by completing a 
follow-up a Clinical Trial Pregnancy Form. If the pregnancy is associated with an SAE 
(e.g., if the mother is hospitalized for hemorrhage), a separate SAE Form for Clinical 
Trials must be filed as described in Section 9.5.2.6 with the appropriate serious criterion 
(e.g., hospitalization) indicated in addition to the Pregnancy Form.

9.5.3
Investigational Product Concentration Measurements
Blood samples will be collected by a qualified phlebotomist via venipuncture using 
lavender-top Vacutainer tubes containing potassium K2EDTA as the anticoagulant. A 
2-mL tube will be used to collect the samples for determination of the plasma 
concentrations of cariprazine and its metabolites.
Four blood samples (2 mL each) will be collected at Visit 4 (Week 2), Visit 5 (Week 4), 
Visit 6/ET (Week 6), and Visit 7 (Week 7). Samples may be collected at any time during 
the visit. The date and time of plasma sampling will be recorded in the eCRF along with 
the date and approximate time of the previous 3 doses of investigational product. Every 
effort should be made to collect PK samples for each patient. However, if for reasons of 
safety or patient refusal, blood sampling is not possible, the PK sample can be skipped. 
All Vacutainer and plasma collection tubes must be prechilled in an ice bath before use.
The clock times of all blood draws will be recorded for each patient. All Vacutainer and 
polypropylene tubes will be labeled at the study center with a code number that 
corresponds to the PID number, visit number, date, and blood draw time. The central 
laboratory will supply the labels with code numbers, blood Vacutainer tubes, and the 
polypropylene tubes. Other laboratory supplies are the responsibility of the Investigator.
Samples must be centrifuged for plasma harvesting within 30 minutes of blood draw.
For details on blood sample collection, plasma separation, storage, and shipment, see the 
instructions from the central laboratory (Central Laboratory Manual).

DATA QUALITY ASSURANCE
9.6.1
Data Monitoring
Before any patient enters the study, a Sponsor representative will meet with the 
Investigator and the study site staff to review the procedures to be followed during the 
study. Electronic data capture (EDC) functionality training is provided via 
computer-based training to train Investigators and authorized designees on recording the 
data in the eCRFs using the EDC system. After the first patient is enrolled, the Sponsor
representative, a Regional Site Manager (RSM) or designee, will periodically monitor the 
progress of the study by conducting on-site visits. This RSM or designee will review 
query statuses remotely, possibly warranting more frequent communication and/or site 
visits with the Investigator and the study site staff. The Investigator will make available 
to the RSM or designee source documents (written notes and electronic medical records, 
if used), signed consent forms, and all other study-related documents. The Investigator
and the study site staff will be responsible for data entry of patient data into the eCRFs
via the EDC system, resolving data queries generated via the EDC system and providing 
missing or corrected data. The Investigator or designee will be responsible for approving 
all changes performed on the data, and endorsing the patient data within the EDC system. 
This approval method will include applying an electronic signature linked to a uniquely 
assigned username and password that together will represent a traditional handwritten 
signature used in the past.
9.6.2
Data Recording and Documentation
Data collection will involve the use of the Sponsor’s EDC system, to which only 
authorized personnel will have access. Patient’s data are to be entered into the EDC 
system by the Investigator or designee using their assigned EDC user account. After data 
entry into the EDC system by the Investigator or designee, a combination of manual and 
programmatic edit checks will be used to review the data for completeness, logic, and 
adherence to study protocol. As a result of these edits checks, data monitoring and
reviews; queries may be electronically issued to the site and should be answered 
electronically via the EDC system.
Each query will carry identifying information (assigned username, date and time) to 
assist the Sponsor and the Investigator on the origin of the data clarification request and 
the response provided by the Investigator. All data changes made to the patient’s data via 
a data query will be approved by the Investigator prior to final database lock.
After all data have been reviewed and all issues have been resolved, the database will be 
locked.

All data collected in the context of this study will be stored and evaluated per regulatory 
requirements and applicable guidance for electronic records. Also, data will be stored and 
evaluated in such a way as to guarantee patient confidentiality in accordance with the 
legal stipulations applying to confidentiality of data. Study records (e.g., copies of 
eCRFs, laboratory reports, patient diaries, regulatory documents, etc.) will be retained at 
the site, along with adequate source documentation, according to FDA and ICH 
requirements. All study records must be available for inspection by the Sponsor, its 
authorized representatives, and the FDA or other health authorities.
9.7
STATISTICAL METHODS AND DETERMINATION OF 
SAMPLE SIZE
9.7.1
Patient Populations
Four populations will be considered in the statistical analysis of the study.
9.7.1.1
Screened Population
The Screened Population will consist of all patients who signed informed consent and 
received a PID number.
9.7.1.2
Randomized Population
The Randomized Population will consist of all patients in the Screened Population who
were randomized to a treatment group in the study.
9.7.1.3
Safety Population
The Safety Population will consist of all patients in the Randomized Population who took 
at least 1 dose of double-blind investigational product.
9.7.1.4
Intent-to-Treat Population
The Intent-to-Treat (ITT) Population will consist of all patients in the Safety Population 
who had at least 1 postbaseline assessment of MADRS total score.
9.7.2
Patient Disposition
The number and percentage of patients in 3 of the study populations (Randomized, 
Safety, and ITT) will be summarized by treatment group and study center; the Screened 
Population will be summarized overall only by study center.
 
Forest Laboratories, LLC
Page 57 of 121
17 Feb 2016
Amended Protocol RGH-MD-53 Amendment 2

Screen-failure patients (ie, patients screened but not randomized) and the associated 
reasons for failure to randomize will be tabulated overall for the Screened Population. 
The number and percentage of patients who completed the double-blind treatment period, 
and of patients who prematurely discontinued during the same period and who entered 
the safety follow-up period will be presented for each treatment group and pooled across 
treatment groups for the Randomized Population. Patients are considered to have entered 
the safety follow-up period if they had Visit 7 (Week 7). The reasons for premature 
discontinuation from the double-blind treatment period as recorded on the termination 
pages of the eCRFs will be summarized (number and percentage) by treatment group for 
the Randomized Population.
9.7.3
Demographics and Other Baseline Characteristics
Demographic parameters (e.g., age, race, ethnicity, sex, weight, height, BMI) and other 
baseline characteristics will be summarized by treatment group for the Safety and 
ITT populations.
Prior medication is defined as any medication taken before the date of the first dose of 
double-blind investigational product. Concomitant medication is defined as any 
medication taken on or after the date of the first dose of double-blind investigational 
product.
Both prior and concomitant medication use will be summarized by the number and 
proportion of patients in each treatment group receiving each medication within each 
therapeutic class for the Safety Population. Multiple medication use by a patient will only 
be counted once.
9.7.4
Extent of Exposure and Treatment Compliance
9.7.4.1
Extent of Exposure
Exposure to double-blind investigational product for the Safety Population during the 
double-blind treatment period will be summarized for treatment duration, calculated as 
the number of days from the date of the first dose of double-blind investigational product 
taken to the date of the last dose taken, inclusive. Descriptive statistics (n, mean, standard
deviation, minimum, median, and maximum) will be presented by treatment group.
 
Forest Laboratories, LLC

17 Feb 2016
Amended Protocol RGH-MD-53 Amendment 2

9.7.4.2
Measurement of Treatment Compliance
Dosing compliance for a specified period is defined as the total number of capsules 
actually taken by a patient during that period divided by the number of capsules that were 
expected to be taken during the same period multiplied by 100. The total number of 
capsules actually taken during a specific period is calculated as the number of days in that 
period multiplied by the number of capsules taken each day during that period. The 
number of capsules expected to be taken for a specific treatment period will be calculated 
by multiplying the number of days in that period by the number of capsules to be taken 
per day. Descriptive statistics for investigational product compliance will be presented by 
treatment group for each period between 2 consecutive visits, as well as for the whole 
double-blind treatment period of the study for the Safety Population.
9.7.5
Efficacy Analyses
All efficacy analyses will be based on the ITT Population, unless stated otherwise. The 
baseline for each specific efficacy endpoint is defined as the value recorded at 
Visit 2/Week 0. If this value is not available, the last available value before the first dose 
of double-blind investigational product will be used as the baseline value. Efficacy results 
will be considered to be statistically significant after consideration of the 
multiplicity-control strategy for controlling the Type I error at 0.05 level; details are 
described in Section 9.7.5.2. Nominal p-values may be computed for other efficacy 
analyses as a measure of strength of association between the endpoint and the treatment 
effect rather than formal tests of hypotheses. All statistical hypothesis tests will be 
performed at the 2-sided 5% significance level for main effects. All confidence intervals 
will be 2-sided 95% confidence intervals, unless stated otherwise.
For efficacy analyses in which study center is a factor, a small center will be defined as a 
center with fewer than 2 patients in at least 1 treatment group in the ITT Population. 
Small centers will be pooled to form pseudo-centers so that each treatment group 
includes at least 2 ITT patients within the center. Pooling will be done within each 
country using the following algorithm: 
Based on the number of ITT patients, small centers will be ordered from the largest to the 
smallest, and centers of the same size will be ordered from the largest center number to 
the smallest center number. The pooling process starts with the largest small center from 
the top, which will be pooled with the smallest from the bottom until a non-small center 
is formed. The process will be repeated using the small centers left out after the first pass. 
If any centers are left out at the end of the process, they will be pooled with the smallest 
pseudo-center. If there is more than 1 smallest pseudo-center, the pseudo-center with the 
smallest center number will be selected. In case that the pseudo center formed by pooling 
all small centers is still a small center, it will be pooled with the smallest non-small 
center. If there is more than 1 smallest non-small center, the one with the smallest center 
number will be selected.

These pseudo-centers will be used for all efficacy analyses when the model is adjusted 
for study center.
 
 
 
 
 
9.7.5.1
Primary Efficacy Parameters
The primary efficacy parameter will be the change from baseline to Week 6 in MADRS 
total score. The primary analysis will be performed using a MMRM with treatment 
group, study center, visit, and treatment group–by-visit interaction as fixed effects and 
the baseline value and baseline by-visit interaction as covariates. An unstructured 
covariance matrix will be used to model the covariance of within-patient scores. The 
Kenward-Roger approximation will be used to estimate denominator degrees of freedom. 
The analysis will be performed based on all postbaseline scores using only the observed 
cases without imputation of missing values.

9.7.5.2
Secondary Efficacy Parameters
The secondary efficacy parameter will be change from baseline to Week 6 in CGI-S 
score. The secondary efficacy parameter will be analyzed using an MMRM with 
treatment group, study center, visit, and treatment group–by-visit interaction as fixed 
effects and the baseline CGI-S score and baseline CGI-S score–by-visit interaction as the 
covariates. An unstructured covariance matrix will be used to model the covariance of 
within-patient scores. The Kenward-Roger approximation will be used to estimate 
denominator degrees of freedom.
To control the overall type I error rate for multiple comparisons of 2 active doses versus 
placebo at Week 6 for the primary and secondary efficacy parameters, the parallel 
gatekeeping procedure will be implemented (Chen et al, 2005). The 4 null hypotheses 
will be grouped into 2 families denoted by F1 and F2, with F1 consisting of 2 null 
hypotheses for comparisons of the 2 active doses versus placebo in change from baseline 
to Week 6 in MADRS total score, and F2 consisting of 2 null hypotheses for comparisons 
of the 2 active doses versus placebo in change from baseline to Week 6 in CGI-S score. 
Family F1 will serve as the parallel gatekeeper for F2. The matched gatekeeping 
procedure utilizes the special logical relationship between the primary and the secondary 
parameters to enhance the power of statistical testing. The secondary efficacy parameter 
will be tested at a specific dose only if the corresponding primary efficacy parameter is 
statistically significant. The Simes test will be used to derive the local p-values for the 
interaction hypotheses. The adjusted p-values for the 4 elementary hypotheses will be 
calculated based on the closed testing principle. Statistical significance will be 
determined by comparing the adjusted p-values to α = 0.050.

9.7.6.6
Investigational Product Plasma Concentration Parameters
Plasma samples will be analyzed for the concentrations of cariprazine and its desmethyl 
and didesmethyl metabolites using a validated bioanalytical method. A population PK 
approach will be used to estimate individual-level drug-exposure parameters 
(i.e., steady-state area-under-the-curve (AUC), steady-state maximum concentration 
[Cmax], steady-state minimum concentration [Cmin]) for each of the 3 analytes. This will 
be performed via the use of appropriate nonlinear mixed-effects modeling software. The 
effects of demographics/covariates (eg, gender, body weight, height, concomitant 
medications) on the pharmacokinetics of the 3 analytes will be evaluated. The 
relationship, if any, between effectiveness and drug-exposure parameters will be 
explored.

9.7.9
Determination of Sample Size
The primary efficacy endpoint is the change from baseline at Week 6 in MADRS total 
score. The secondary endpoint is the change from baseline at Week 6 in CGI-S score. For 
the comparison of the primary endpoint, the sample size of 160 subjects per arm will 
provide approximately 82% statistical power to show statistically significantly higher 
effect in each dose of cariprazine versus placebo. The study has statistical power of 90% 
to show at least one of the two cariprazine doses is statistically significantly more 
efficacious than placebo in the primary endpoint. These calculations assumed an effect 
size of 0.36 (treatment group difference relative to SD). For a given successful 
(statistically significant) dose versus placebo with respect to the primary endpoint, its 
probability in detecting an effect size of 0.36 as statistically significant versus placebo 
with respect to the secondary endpoint is 88%. All statistical powers presented in this 
section were calculated adjusting for multiple comparisons using matched parallel 
gatekeeping procedure with the family-wise Type I error rate being controlled at a 0.05 
level (2-sided). The dropout rate is assumed to be 22% at Week 6. Within-person 
correlation for both primary and secondary endpoints is assumed to be 0.6, as well as 
correlation between the two endpoints (primary and secondary) to be 0.6. Assumptions of 
effect sizes, correlation coefficients, and drop-out rate are based on RGH-MD-56 study.

Computer Methods
Statistical analyses will be performed using version 9.1.3 (or newer) of SAS on a

PROTOCOL DEVIATIONS AND VIOLATIONS
A protocol deviation is any change, divergence, or departure from the study design or 
procedures that is under the Investigator’s responsibility and oversight (as defined by 
regulations) without prior written IRB/IEC approval or favorable opinion of an 
appropriate amendment and that does not have a major impact on the patient’s rights, 
safety, or well-being, or on the integrity and authenticity of the study data. Deviations 
may include, but are not limited to, departure from inclusion/exclusion criteria, dosing, 
duration of treatment, failure to perform the required assessments at specified time points, 
scheduling of visits not in accordance with specifications, or patient safety. Deviating 
from the protocol is permitted only if absolutely necessary for the safety or clinical 
management of the patients and must immediately be reported to the Sponsor.
Protocol deviations must be reported to the Sponsor either verbally or electronically 
within 5 working days from the day of discovery.
A protocol violation is a form of protocol deviation that has a major impact on the 
patient’s rights, safety, or well-being, or on the integrity and authenticity of the study 
data.
Protocol violations must be reported to the Sponsor within 24 hours, if possible. The 
IRB/IEC must be notified within the time period dictated by the IRB/IEC associated with 
this study.

APPENDIX IV.
MONTGOMERY-ÅSBERG DEPRESSION RATING SCALE
Montgomery Åsberg Depression Rating Scale (MADRS)
The rating should be based on a clinical interview moving from broadly phrased 
questions about symptoms to more detailed ones which allow a precise rating of severity. 
The rater must decide whether the rating lies on predefined scale steps (0, 2, 4, 6) or 
between them (1, 3, 5).
It is important to remember that it is only on rare occasions that a depressed patient is 
encountered who cannot be rated on the items in the scale. If definite answers cannot be 
elicited from the patient all relevant clues as well as information from other sources 
should be used as a basis for the rating in line with customary clinical practice.
The scale may be used for any time interval between ratings, be it weekly or otherwise, 
but this must be recorded.
