4. Introduction 
4.1 Background 
Schizophrenia generally appears in puberty or adolescence and is characterized by various 
psychiatric symptoms including positive symptoms (eg, hallucination, delusion) and negative 
symptoms (eg, blunted affect, disorganized thinking, lack of motivation). Cognitive symptoms (eg, 
reduced ability to pursue goals or process information) also occur in some cases. Schizophrenia is a 
chronic psychiatric disease with repeated relapses which can be triggered by drug refusal and self-
medicating. 
Therefore, treatment adherence is of interest as a means of symptom control in order to involve 
patients in decision making processes regarding their therapeutic strategy and pursue aggressive 
treatment for schizophrenia. Adherence is, however, one of the major challenges in for schizophrenia 
treatment. Maintaining adherence to treatment is often difficult for patients with schizophreniaref 1. 
Relapse of schizophrenia or re-hospitalization are mainly caused by poor adherence. Among patients 
with schizophrenia, 35% of hospitalized patients are deemed non-adherent to medication regimensref 2. 
Shared decision making (SDM) among physicians and patients regarding their therapeutic strategy is 
essential for improving adherence. A useful way of implementing SDM may be to provide multiple 
therapeutic options to patients with schizophrenia and then to make a mutual decision, which takes the 
patient’s opinion into accountref 3,4. 
As factors affecting adherence, environmental, drug and patient factors have all been discussed. 
Drug formulations have also been emphasized in recent yearsref 2, and various formulations have been 
or are being developed. Transdermal formulations, which can reduce dosing frequency and 
invasiveness, are used for treating various diseases. For schizophrenia treatment, however, no 
transdermal formulations are as yet available anywhere in the world and only injections or oral 
formulations (eg, tablet, powder, orally disintegrating tablets, liquids) are used. If a transdermal 
formulation is available for schizophrenia treatment and is provided to patients as a new option during 
the SDM process, adherence may be improvedref 5. 
Blonanserin is a second-generation antipsychotic synthesized by Sumitomo Dainippon Pharma Co., 
Ltd.. Blonanserin, which is a potent antagonist of dopamine D2 and serotonin 5-HT2A receptors, with 
a lower affinity for adrenaline α1, serotonin 5-HT2c, histamine H1, and muscarinic M1 receptorsref 6, is 
approved and marketed for the treatment of schizophrenia in Japan (tablet and powder formulation) 
and Korea (tablet formulation). DSP-5423P, a transdermal blonanserin patch is currently being 
developed as a new formulation of blonanserin with the aim of improving adherence as described 
above. 
 
4.2 Study Conduct Rationale  
In the clinical study in Japanese healthy adults, 1, 2, or 3 patches of DSP-5423P 32 mg/40 cm2 were 
applied to 9 patients each for 24 hours. In addition, 2 patches of DSP-5423P 32 mg/40 cm2 were

DSP-5423P

applied to 9 patients once daily for 10 days. The results showed that the plasma blonanserin 
concentration increased depending on the number of patches applied and that the steady state was 
nearly reached after repeated administration for 7 days. 
A new patch formulation, DSP-5423P 20 mg/40 cm2 was prepared. Pharmacokinetics, after the 
application of a single patch, were compared between these 2 patch formulations. The results showed 
that a comparable amount of blonanserin absorption was obtained with these 2 patch formulations. 
Therefore, the new formulation, DSP-5423P 20 mg/40 cm2 was used in the following studies. 
The phase 2 study of DSP-5423P was conducted in patients with schizophrenia to determine the 
recommended doses for phase 3 studies. Striatal dopamine D2 receptor occupancy and plasma drug 
concentrations after application of DSP-5423P at doses of 10 to 80 mg/day for 2 weeks were compared 
with results obtained after administration of DSP-5423 (tablet formulation of blonanserin). The results 
suggest that DSP-5423P 40 mg/day and 80 mg/day may be comparable to DSP-5423 (tablet) 8 mg/day 
and 16 mg/day, respectively. Since the clinical efficacy of antipsychotics reportedly correlates with 
dopamine D2 receptor occupancyref 7, 8, DSP-5423P at doses of 40 and 80 mg/day is expected to 
demonstrate efficacy corresponding to that of DSP-5423 (tablet) at doses of 8 and 16 mg/day, 
respectively. In clinical studies of DSP-5423P in healthy adult volunteers or subjects with 
schizophrenia, no clinically significant adverse events have been reported at doses up to 80 mg, 
demonstrating tolerability on the skin of application sites. 
Considering these results, a phase 3 confirmatory study is currently being conducted in a 
randomized double-blind, placebo-controlled, parallel-group manner to confirm the superiority to 
placebo in order to evaluate the efficacy and safety of DSP-5423P. 
The phase 3 long-term study is designed to evaluate (1) the long-term safety, effectiveness and 
pharmacokinetics of DSP-5423P, (2) the safety and effectiveness of switching from DSP-5423 (tablet) 
to DSP-5423P in patients with schizophrenia. The clinical study is an uncontrolled, open-label study 
consisting of cohort 1 with DSP-5423P applied for 52 weeks after administration of the DSP-5423 
(tablet) for 6 weeks and cohort 2 with DSP-5423P applied for 52 weeks. The dose of DSP-5423P 
should be 40-80 mg/day, and the dose of DSP-5423 (tablet) should be 8-16 mg/day, the approved dose 
for maintenance.

7.1 Overall study design of clinical study 
This clinical study is a multicenter, uncontrolled, open-label, long-term administration study 
consisting of two cohorts. The study schematics of clinical study are presented in Figures 1 (cohort 1) 
and 2 (cohort 2). Details of the study assessment and other procedures (assessment, observation, 
laboratory test) to be performed are presented in Tables 2 (cohort 1), 3 (cohort 2) and Chapter 11. In 
both cohorts, Day 1 is defined as the day of the initial application of DSP-5423P. 
Cohort 1, consisting of DSP-5423 (tablet) treatment phase and DSP-5423P treatment phase, and 
cohort 2, consisting only of DSP-5423P treatment phase, will be conducted in different subjects, and 
cohort 2 will be initiated after enrollment in cohort 1 has been completed. Enrollment in cohort 1 will 
be terminated when the number of total subjects whose DSP-5423P treatment duration is 6 weeks or 
more reached 50. At the completion of enrollment in cohort 1 and at the initiation of enrollment in 
cohort 2, the sponsor will notify the participating study centers of that. 
 
7.1.1 Cohort 1 
Cohort 1 consists of 3 phases: DSP-5423 (tablet) treatment phase (6 weeks), DSP-5423P treatment 
phase (52 weeks) and follow-up phase (1-2 weeks). Prior to initiation of DSP-5423 (tablet) treatment 
phase, washout period (up to 4 weeks) will be arranged (see Section 10.3.3.1) according to the dose 
of prior antipsychotics (haloperidol equivalent). 
DSP-5423 (tablet) treatment phase 
DSP-5423 (tablets) will be administered orally twice daily after breakfast and evening meal

7.2 Rationale 
7.2.1 Rationale for the study design 
The study is designed to evaluate the long-term safety and effectiveness of DSP-5423P as an 
uncontrolled open-label study with treatment duration of 52 weeks. The dosage of DSP-5423 (tablet) 
and DSP-5423P was selected as flexible-dose. 
Switching from oral bronanserin to DSP-5423P is potential regimen when DSP-5423P is marketed. 
In addition, in the result of a phase II study (PET study, D4904019) which was conducted in order to 
evaluate dopamine D2 receptor occupancy by positron emission tomography (PET) in patients with 
schizophrenia, the result suggests that a higher concentration of plasma bronanserin than DSP-5423 
(tablet) is needed for DSP-5423P to achieve a similar dopamine D2 receptor occupancy as DSP-5423 
(tablet). Therefore, we decided to design a DSP-5423P treatment phase after DSP-5423 (tablet) 
treatment phase that the initial dose of DSP-5423P is determined by the final dose of DSP-5423 (tablet)

in order to evaluate the effect of safety and effectiveness in the case of the switching from oral 
bronanserin to DSP-5423P 
. 
7.2.2 Rationale of dose, mode of administration and duration of administration 
DSP-5423P 
A once-daily regimen was selected since plasma drug concentrations were maintained with minimal 
change within 24-hour intervals over time in the phase 1 study (Study No. D4904016) of DSP-5423P 
in Japanese healthy adults.  
Striatal dopamine D2 receptor occupancy after administration of DSP-5423 (tablet) or application 
of DSP-5423P was evaluated in subjects with schizophrenia by positron emission tomography (PET) 
in the phase 2 study (Study No. D4904019). 
In a comparison of occupancy between subjects treated with 8 mg/day of DSP-5423 (tablet) and 
those treated with 40 mg/day of DSP-5423P or between subjects treated with 16 mg/day of DSP-5423 
(tablet) and those treated with 80 mg/day of DSP-5423P, occupancy after application of DSP-5423P 
was within the range after administration of DSP-5423 (tablet) at the first (trough) and second (peak) 
measurements.   
The DSP-5423P dose is selected based on the above occupancy results.  DSP-5423P doses of 
40 mg/day and 80 mg/day are considered to be comparable to DSP-5423 (tablet) at doses of 8 mg/day 
and 16 mg/day, respectively.  DSP-5423 (tablet) at doses ranging from 8 to 16 mg/day is approved 
for the treatment of schizophrenia.  For DSP-5423P, 40 -80 mg/day are to be used in this study. 
From the results of the single dose study (Study No. D4904016) and the location of the application 
comparative study (Study No. D4904059), the amounts of absorption after application to the chest, 
the lower back, the upper arm, or the abdomen were comparable to that after application to the upper 
back.  Therefore, the back, chest, and abdomen were selected as the locations of application in this 
study.  The upper arm, which is more likely to be exposed to light, is excluded because DSP-5423P 
may be a photosensitizer (nonclinical study, No. P110808). 
Based on the Yakushin (Pharmaceutical Affairs Bureau Examination Division ：PAB/ED) 
notification No. 592 of May 24th 1995, "Recommendation on the numbers of patients and duration of 
exposure for the safety evaluation of drugs intended for the long-term treatment of non-lifethreatening 
conditions" one year (52 weeks) was selected as the duration of administration. 
 
DSP-5423 (tablets) 
Based on the approved dose of blonanserin tablet, the initial dose of DSP-5423 (tablet) was set at 
8 mg/day and the dose was increased or decreased according to the maintenance dose (8-16 mg/day). 
Oral administration was planned after meal (in the morning and in the evening) in accordance with the 
approved treatment regimen of blonanserin tablet. 
Since initial dose was set at 8 mg/day, it was considered necessary to determine the optimal dose 

Protocol No. D4904040 1.02 
DSP-5423P 
25 
 
Confidential and Proprietary :30 October 2015 
for 2 weeks. It has been reported that the treatment response assessment of antipsychotics should be 
performed 2 to 4 weeks after administration initiation ref 11). Furthermore, in the clinical studies of 
DSP-5423 (tablets) conducted in Japan, most of the common/frequent adverse events, including 
akathisia, tremors, insomnia, and increased blood prolactin, have been observed in 4 weeks after 
administration initiation. Therefore, 6-week was set as the duration enough to collect effectiveness and 
safety data on DSP-5423 (tablet). 
 
7.2.3 Rationale of endpoints 
Efficacy endpoints 
PANSS and CGI-S, which are frequently used as endpoints in the clinical study of antipsychotics, 
were set. In addition, because treatment of antipsychotics is often terminated due to adverse drug 
reaction and/or lack of efficacy, we considered that duration of DSP-5423P would be helpful in 
evaluating the effectiveness of antipsychotic drugs and decided to be endpoints. 
Pharmacokinetic endpoints 
To investigate the pharmacokinetics of DSP-5423P application, bronanserin and the main 
metabolite, M-1, are measured in both cohort 1 and cohort 2. In addition, in cohort 1, the metabolites 
other than M-1 are also measured in order to compare the pharmacokinetics of DSP-5423P application 
with that of DSP-5423 (tablet) administration, which has a higher metabolite production ratio, in the 
same subject. 
Safety endpoints 
Since DSP-5423P is transdermal formulation, skin-related adverse event/ adverse drug reaction at 
the application site and skin irritation assessment were set. 
Other endpoints 
Because DAI-10 is one of the commonly used measures of adherence, and because EQ-5D is one 
of the commonly used measures of health-related Quality of life (QOL) as a comprehensive measure, 
DAI-10 and EQ-5D were set. In addition, questionnaires on the dosage form were set to investigate 
the impressions of subject on the DSP-5423P. 
 
7.3 Measures to prevent missing data 
The following study design and conduct elements are implemented in an effort to minimize the 
number of subjects who are terminated from the study before the completion; 
1) Depending on the dose of prior antipsychotics, washout period can be arranged. 
2) Adequately wide visit windows were set for each Visit. 
3) During the entire study period, concomitant use of antiparkinson drugs, lorazepam, and 
hypnotic drugs are allowed for extrapyramidal symptoms, psychiatric symptoms, and insomnia 
respectively. 
4) Rescue use of antipsychotics is allowed for urgent psychiatric symptoms. 

Protocol No. D4904040 1.02

5) Flexible dose adjustment is allowed based on effectiveness or tolerability. 
6) train the study centers on the importance of continued follow-up and on the informed consent 
process, ensuring subjects understand the commitment they are making, including the intent to 
complete the trial. 
7) Monitor data collection for adherence during the study.

1) The DSP-5423P will be applied directly to normal healthy skin after removing the transparent 
liner. 
2) DSP-5423P will be replaced every day. When DSP-5423P patches are replaced, new DSP-
5423P will be applied as soon as possible In addition, the new patches will be applied to the 
location different from that of the last application, or a site different from that of the last 
application on the same location. 
3) The current application site of the study drug will be protected from heat.  For instance, the 
application site should not be warmed with a portable body warmer or hot air from a heater. 
4) The current application site of DSP-5423P will be protected from water.  Before taking a bath 
or shower, DSP-5423P should be removed.  After taking a bath or shower, new patches should 
be immediately applied to thoroughly dried skin (within approximately 1 hour after removing 
the previous patches). 
5) The locations of previous and current applications of the study drug will be protected from 
light outdoors by clothing or other appropriate measures from the beginning of DSP-5423P 
application until the follow-up visit. 
6) No other adhesive skin patches are to be overlaid on the current application site of DSP-5423P.  
No liniments should be used at the current application site of DSP-5423P.  The study drug 
should not be applied to any site where liniments are used. 
7) Surgical tape should be used to maintain DSP-5423P at the application site if any patches are 
detached or are about to become detached.  When patches which have detached from the 
application site cannot be reapplied, no new patches will be applied until the next scheduled 
application. 
8) The used patches will be adequately disposed to prevent anyone else from misusing them. 
 
10.2 Dose adjustment criteria 
The DSP-5423P dose can be increased or reduced by 20 mg/day at each adjustment within a range 
of 40 mg/day, 60 mg/day or 80 mg/day according to the following dose adjustment criteria.  The 
DSP-5423 (tablet) dose can be increased or reduced by 4 mg/day at each adjustment within a range of 
8 mg/day, 12 mg/day or 16 mg/day according to the following dose adjustment criteria. 
 
Regulatory Assessment timing 
- When the CGI-S score is between 4 and 7 and when no safety concerns arise, the DSP-
5423P/DSP4323 (tablet) dose should be increased. 
- When the CGI-S score is 3 or lower with no safety concerns and when the Investigator expects 
further efficacy of DSP-5423P/DSP4323 (tablet), the DSP-5423P/DSP4323 (tablet) dose can 
be increased. 

Protocol No. D4904040 1.02 
DSP-5423P 
33 
 
Confidential and Proprietary :30 October 2015 
As necessary 
- When the Investigator considers a higher dose of DSP-5423P/DSP4323 (tablet) to be necessary 
due to insufficient efficacy, the DSP-5423P/DSP4323 (tablet) dose can be increased. 
- When the Investigator considers a lower dose of DSP-5423P/DSP4323 (tablet) to be necessary 
due to the AEs, the DSP-5423P/DSP4323 (tablet) dose can be reduced. 
 
PANSS and CGI-S should be evaluated before the dose adjustment at each unscheduled visit 
(Section 11.2 Efficacy Assessments).  DIEPSS should be evaluated as well as PANSS and CGI-S 
when the DSP-5423P/DSP4323 (tablet) dose is reduced due to extrapyramidal symptoms (Section11.3 
Safety Assessments). 
After the dose adjustment, the Investigator will record the reason for the dose adjustment in the 
CRFs.  The DSP-5423P/DSP4323 (tablet) dose should not be changed for at least 1 week in principle, 
after the dose adjustment. 
 
10.3 Concomitant medications and therapies

wash-out period, if needed. 
b) If the prior antipsychotics dose is over 12.0 mg/day (haloperidol equivalent) 
The prior antipsyochotics should be tapered. After the dose of the prior antipsychotics is 
12 mg/day or less (haloperidol equivalent), these antipsychotics should be completely 
discontinued, through tapering during the wash-out period, if needed.  
 
If urgent treatment is required because of psychiatric symptoms such as acute psychomotor 
excitability, at the discretion of the Investigator, only one antipsychotic drug excluding depot 
neuroleptics and blonanserin can be used concomitantly on an as-needed basis.  However, all 
antipsychotics will be prohibited within 48 hours before the PANSS, CGI-S, and C-SSRS assessments.

application period, antiparkinson drugs may be used. While the drugs listed in Table 11 are 
recommended, other antiparkinson drugs will be permitted.  If the extrapyramidal symptoms improve, 
antiparkinson drugs may be tapered or discontinued.  
Note that for the subjects who started the administration of antiparkinson due to extrapyramidal 
symptom occurred or worsen during the DSP-5423 (tablet) period in cohort 1, if the subject continued 
the antiparkinson drugs at transition to the DSP-5423P application period, the antiparkinson drugs 
should be tapered and discontinued in 2 weeks beginning of the DSP-5423P application, as much as 
possible.

12. SAFETY REPORTING 
12.1 Definition 
12.1.1 Adverse events 
An adverse event (AE) is any untoward medical occurrence in a study subject administered a 
medicinal (investigational) product and which does not necessarily have a causal relationship with this 
treatment.  An AE can, therefore, be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease occurring after the administration of a medicinal 
(investigational) product, whether or not considered related to the medicinal (investigational) product.  
AEs may include the onset of new illness and the exacerbation of pre-existing conditions.  AEs will 
be collected from the beginning of the study treatment in the washout phase until the follow-up visit. 
AEs also include other untoward events occurring from the beginning of the DSP-5423 (tablet) 
administration until the follow-up visit in the cohort 1, or from the beginning of the DSP-5423P 
application until the follow-up visit in the cohort 2, for instance, events occurring in association with 
study-related procedures or assessments, or those occurring under placebo treatment. 
In the cohort 1. AEs that occur during the DSP-5423 (tablet) administration period and worsen 
during the DSP-5423P application period will be recorded as AEs in the DSP-5423 (tablet) 
administration period and also as AEs in the DSP-5423P application period. The date of worsening 
will be recorded as the onset date of the worsening AE. In addition, AEs that occur during the DSP-
5423 (tablet) administration period without further worsening in the DSP-5423P application period 
will be recorded as AEs in the DSP-5423 (tablet) administration period.  
Lack of efficacy may be an expected potential outcome and should not be reported as an AE unless 
the event is unusual in some way.  New signs and symptoms of the underlying disease, or signs and 
symptoms of an emerging disease should be recorded as AEs. 
The Investigator should attempt to establish a diagnosis of the event based on signs, symptoms, 
and/or other clinical information.  In such cases, the diagnosis should be recorded as the AE and not 
the individual signs/symptoms. 
 
12.1.2 Serious adverse events 
A serious adverse event (SAE) is an AE that meets one or more of the following criteria: 
- Results in death. 

Protocol No. D4904040 1.02 
DSP-5423P 
45 
 
Confidential and Proprietary :30 October 2015 
- Is life-threatening (ie, a subject is at immediate risk of death at the time of the event, not an 
event where occurrence in a more severe form might have caused death). 
- Requires hospitalization or prolongation of existing hospitalization. 
- Results in persistent or significant disability or incapacity. 
- Is a congenital anomaly or birth defect. 
- Is an important medical event that may jeopardize the subject or may require a medical or 
surgical intervention to prevent one of the outcomes listed above. 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 inpatient hospitalization. 
 
The term "severe" is often used to describe the severity of a specific event (as in mild, moderate, or 
severe myocardial infarction) (see Section 12.3); the event itself, however, may be of relatively minor 
medical significance (such as severe headache).  This is not the same as "serious," which is based on 
subject/event outcome or action criteria usually associated with events that pose a threat to a subject's 
life or functioning as defined by the criteria above.  
During the study, if a subject has a hospitalization or procedure that was scheduled before the study 
entry, ie, before informed consent for an event/condition that occurred before the study, the 
hospitalization is considered a therapeutic intervention and not the result of a SAE.  However, if the 
event/condition worsens during the study, it should be reported as an AE (or SAE, if the 
event/condition results in a serious outcome such as prolongation of hospitalization). 
 
12.2 Objective Findings 
Clinically significant abnormal objective findings (eg, clinical laboratory value, ECG value, and 
physical examination observation) will also be recorded as AEs.  When a clear diagnosis is available 
that explains the objective findings, this diagnosis will be recorded as the AE, and not the abnormal 
objective finding (eg, viral hepatitis will be recorded as the AE, not transaminase elevation).  If a 
definite diagnosis is not available, then record the sign (eg, clinically significant elevation of 
transaminase levels) or symptom (eg, abdominal pain) as the AE. 
 
Clinical laboratory test results will be reviewed by the Investigator.  The Investigator must 
determine the clinical significance of all out of range values.  Clinical laboratory test with possibly 
drug-related or clinically relevant abnormal values of uncertain causality may be repeated.  Any 
abnormal values that persist should be followed at the discretion of the Investigator.  Laboratory 
reports will be initialed and dated by the Investigator. 
 
All ECG tracings at the study center and ECG over-read reports by the central ECG reader will be 
reviewed by the Investigator.  The Investigator must determine the clinical significance of all 

Protocol No. D4904040 1.02 
DSP-5423P 
46 
 
Confidential and Proprietary :30 October 2015 
abnormal ECGs.  An ECG with possibly drug-related or clinically relevant abnormal findings of 
uncertain causality may be repeated.  Any abnormal ECGs that persist should be followed at the 
discretion of the Investigator.  ECG tracings will be initialed and dated by the Investigator. 
 
12.3 Collection and Recording of adverse events 
All AEs will be, in principle, followed up until resolution, stabilization of the condition, the event 
is otherwise explained, or the subject is lost to follow-up.  All AEs must be collected and recorded in 
the subject’s study records/source documents, in accordance with the Investigator’s normal clinical 
practice.  AEs will be recorded in the CRFs from the beginning of the study treatment in the washout 
phase until the follow-up visit.     
 
Each AE is to be evaluated for duration, severity, seriousness, action taken with the study treatment, 
outcome, and causal relationship to the study treatment.  If any AEs related to skin disorders occur 
at the application site, the Investigator will record the location (the back, chest or abdomen) of AEs 
occurrence.   
 
Definitions for severity, action taken with the study treatment, outcome, and causal relationship to 
the study treatment are presented below. 
 
The severity of AE: 
- Mild – Ordinarily transient symptoms that do not influence performance of subject’s daily 
activities. Other treatment is not ordinarily indicated. 
- Moderate – Marked symptoms sufficient to make the subject uncomfortable. Moderate 
influence on performance of subject’s daily activities. Other treatment may be necessary. 
- Severe – Symptoms cause considerable discomfort. Substantial influence on subject’s daily 
activities. May be unable to continue the study, and other treatment may be necessary. 
 
The action taken with the study treatment: 
- Drug Withdrawn – Study drug stopped permanently. 
- Dose Reduced. 
- Dose Increased. 
- Dose Not Changed.  
- Not Applicable. 
-  
The outcome of the AE: 
- Recovered/Resolved. 
- Recovering/Resolving. 

Protocol No. D4904040 1.02 
DSP-5423P 
47 
 
Confidential and Proprietary :30 October 2015 
- Not Recovered/Not Resolved. 
- Recovered/Resolved with Sequelae. 
- Fatal. 
- Unknown. 
 
The causal relationship of the AE to the study treatment:  
Not related   
- Not related – Improbable temporal relationship and is plausibly related to other drugs or 
underlying disease. 
Related 
- Possible – occurred in a reasonable time after study drug administration (application), but could 
be related to concurrent drugs or underlying disease. 
- Probable – occurred in a reasonable time after study drug administration (application), is unlikely 
to be attributable to concurrent drugs or underlying disease, and there is a plausible mechanism to 
implicate the study drug.  
- Definite – occurred in a reasonable time after study drug administration (application) and cannot 
be explained by concurrent drugs or underlying disease.  The adverse event should respond to 
dechallenge/rechallenge, however, this is not mandatory before assigning a definite causality. 
 
The Sponsor is the contact person.  The contact information as well as other emergency contact 
information can be found in Table 1 Emergency Contact Information. 
 
12.4 Immediately Reportable Events 
The following medical events must be immediately reported to the Sponsor: 
- SAE 
- Pregnancy 
Emergency contact information can be found in Table 1 Emergency Contact Information. 
 
12.4.1 Serious adverse event 
If the Investigator or staff of study centers becomes aware of SAE that occurs in a study subject 
from the beginning of the DSP-5423 (tablet) administration until the follow-up visit in the cohort 1, 
or from the beginning of the DSP-5423P application until the follow-up visit in the cohort 2, this must 
be reported immediately to the Sponsor whether considered related or unrelated to the study drug.  
SAEs occurring during above period must be recorded in the CRFs. 
Following the end of subject participation in the study, the Investigator should report SAEs 
“spontaneously” to the Sponsor if considered at least possibly related to the study drug.  
 

Protocol No. D4904040 1.02 
DSP-5423P 
48 
 
Confidential and Proprietary :30 October 2015 
SAEs will be followed until resolution, loss to follow-up, stabilization of condition, or the event is 
otherwise explained.  
The Investigator must inform the Sponsor (Table 1 Emergency Contact Information) of any SAEs 
that occur during the course of the study within 24 hours of the Investigator becoming aware of the 
SAE. The SAE report should include the following information; 
- History of any ADRs, relevant special conditions of the subject, history of the current disease 
and treatment for the disease, details of the SAE, treatment for the SAE and details on course 
of the SAE 
- If the subject died, date of death, cause of death, relationship between the SAE and death, 
anatomic findings (if available) 
These SAEs must be promptly reported in writing to the head of the study center by the Principal 
Investigator. The Principal Investigator should report available information in writing after the first 
reporting (this procedure is not mandatory in the case that the Principal Investigator has already 
submitted the first report, including all necessary information listed above).  The Principal 
Investigator should report other necessary information not included in the first and second reports in 
writing as it becomes available.  
The Sponsor will promptly notify all study centers and Investigators of a SAE that is determined to 
be expedited to the Regulatory Authority in accordance with applicable law(s) and regulation(s). 
 
12.4.2 Pregnancy 
Pregnancies that occur from the beginning of the DSP-5423 (tablet) administration until the follow-
up visit in the cohort 1, or from the beginning of the DSP-5423P application until the follow-up visit 
in the cohort 2 will be collected and reported to the Sponsor.  
If a subject becomes pregnant during the above period, she will be instructed to commence 
discontinuation of the study medication.  Further, the subject (or female partner of a male subject) 
will be instructed to return promptly after the first notification of pregnancy to the study center and 
undergo a serum pregnancy test, as confirmation of pregnancy.  If positive, the subject will no longer 
receive any additional study medication.  All pregnancies will be followed until resolution (ie, 
termination [voluntary or spontaneous] or birth).  
If the Investigator becomes aware of pregnancies, this must be promptly reported directly or by 
telephone or facsimile to the Sponsor.  The Investigator must complete the Pregnancy Event Form 
and send it to the Sponsor.   
Pregnancy itself is not regarded as an AE unless there is a suspicion that the study drug may have 
interfered with the effectiveness of a contraceptive medication or other AEs were detected.

13. TERMINATION OF SUBJECT FROM STUDY/DISCONTINUATION OF 
STUDY DRUG 
13.1 Criteria for Subject Termination 
Subjects may terminate the study participation at any time for any reason.  
 
The possible reasons for the termination of study participation are as follows: 
- Adverse event 
- Suicide ideation 
- Study drug discontinuation 
- Lack of efficacy 
- Lost to follow-up 
- Pregnancy 
- Withdrawal by subject 
- Failure to apply >50% of the study medication since the last visit 
- Protocol violation 
- Other 
 
If at any time during the course of the study, in the opinion of the Investigator, the subject may no 
longer safely participate due to a change in medical status (eg, experiences an AE or suicide ideation, 
becomes pregnant), or discontinuation of the study drug should be considered, the subject must be 
discontinued from the study treatment. 
 
The date of discontinuation and the reason for discontinuation will be recorded in the appropriate 
CRF.  Subjects who prematurely terminate the study participation will not be replaced. 
 
13.2 Clinical Assessments after Study Drug Discontinuation 
Every effort should be made for all subjects treated with study drug prematurely discontinuing the 
study drug, regardless of cause, to undergo final evaluation procedures, in accordance with the 
discontinuation visit and the follow-up visit.  Required assessment should be conducted at 
discontinuation visit accordance with the table 2 or 3 (DSP-5423 (tablet administration period or DSP-
5423P application period). If a subject discontinues during the DSP-5423P application period, the 
subject will undergo all the discontinuation assessments in accordance with the discontinuation visit 
as described in Table 2 and 3.  If a subject discontinues during the DSP-5423 (tablet) administration 
period, the subject will undergo the following safety assessments: study treatment compliance, 
DIEPSS, C-SSRS, laboratory test, pregnancy test, 12-lead ECG, body weight, body temperature, blood 
pressure, pulse rate, and adverse event monitoring at the discontinuation visit. 
The subject will undergo the discontinuation assessments within 5 days of the last study drug

administration/application.  
 
14. STUDY TERMINATION  
The Sponsor reserves the right to discontinue the study at multiple study centers for safety or 
administrative reasons at any time while ensuring that early termination does not compromise the 
safety or well-being of the subjects.  Should the study be terminated and/or the study center closed 
for whatever reason, study medications pertaining to the study must be returned to the Sponsor. 
If the Sponsor decides to prematurely terminate the study, the Sponsor will inform the Investigator 
and regulatory authorities of this termination and its reason, and in addition, the head of the study 
center in Japan must be informed.  In the event of study or study center termination, the subjects will 
be provided with access to standard care 
 
 
15. Statistical analysis plan 
Details of the statistical methods will be specified in the statistical analysis plan. The sponsor will 
determine detailed data handling, including adoption or rejection for each subject to analysis 
populations before database hard lock. When separately analyzing the pharmacokinetics and PK-PD, 
the details of the analytical procedures will be specified in an analysis plan and if appropriate pooled 
analysis with other studies will be performed and reported separately. 
 
15.1 Target sample size 
Number of subjects enrolled: 200 subjects 
- Number of subjects treated with DSP-5423P for 6 weeks and more in cohort 1: 50 subjects 
- Number of subjects treated with DSP-5423P for 52 weeks in either cohort 1 or cohort 2: 100 
subjects 
The new enrollment can be terminated at the time when 100 subjects with 52-week exposure of 
DSP-5423P are collected, together with a separate confirmatory study [Confirmatory Study of DSP-
5423P in Patients with Schizophrenia <Phase 3> (protocol: D4904020)]. 
 
Rationale 
Based on the guideline, THE EXTENT OF POPULATION EXPOSURE TO ASSESS CLINICAL 
SAFETY FOR DRUGS INTENDED FOR LONG-TERM TREATMENT OF NON-LIFE-
THREATENING CONDITIONS dated 24 May 1995, 100 subjects with one year (52 weeks) exposure 
of DSP-5423P will be collected in cohort 1 and 2. In addition, to investigate the safety and efficacy of 
switching DSP-5423 (tablet) to DSP-5423P, approximately half of the target number of subjects will 
be enrolled in cohort 1 as subjects who switched DSP-5423 (tablet) to DSP-5423P. Considering 
approximately half of enrolled subjects early terminated in previous studies of DSP-5423 (tablet),

Protocol No. D4904040 1.02 
DSP-5423P 
55 
 
Confidential and Proprietary :30 October 2015 
electronic data capture (EDC) system.  The users of this system should receive EDC training from 
the Sponsor or its delegate.  The data will be recorded in the CRFs in English as soon as data are 
available for entry.  Each set of completed CRFs must be reviewed and electronically signed and 
dated by the Investigator.  
 
The Sponsor will provide copies of the original CRFs for the Principal Investigator, and he/she will 
retain them.  If data are inconsistent with source documents, the Investigator will clarify the lack of 
consistency and record the reason.  The record will be provided to the Sponsor.  The Principal 
Investigator will keep copies of the record. 
If the data need to be revised, the Investigator will comply with the guidance for CRF provided by 
the Sponsor.  
 
Of the data recorded in the CRF, the source documents of the following can be CRFs per se:    
1) The outcome, severity, seriousness of AEs 
2) Causal relationship to the study treatment 
3) The reasons for concomitant use 
4) The reasons for dose changing of study drugs 
5) The reason for discontinuation 
 
16.2 Study Monitoring 
This study will be monitored from initiation to completion by the Sponsor or its representative.  
Monitoring will include personal visits and telephone communication to assure that the investigation 
is conducted according to the protocol and in order to comply with ICH GCP and local regulations.  
On-site review of CRFs will include a review of forms for completeness and clarity, and consistency 
with the source documents available for each subject. 
 
16.3 Audits 
The study may be subject to audit by the Sponsor or designee.  If such an audit occurs, the 
Investigator must agree to allow access to required subject records.  This is dependent on the subject 
granting consent by signing the ICF.  By signing this protocol (affixing a seal with the name on this 
protocol will be also acceptable in Japan), the Investigator grants permission to personnel from the 
Sponsor or its representatives for on-site monitoring and auditing of all appropriate study 
documentation, as well as on-site review of the procedures employed in CRF generation, where 
clinically appropriate.

medical information or test results that have been collected for or are in support of the protocol 
specifications. 
 
16.5 Clinical Laboratory Certification and Normal Values 
A central laboratory will be used for analysis of most of the clinical laboratory tests for this study.  
The central laboratory will provide the Investigator, Sponsor with laboratory certification(s), and a 
dated copy of normal range values for the central clinical laboratory selected to analyze clinical 
specimens.  If an exception is granted to use a local laboratory, the Investigator must supply the 
Sponsor with laboratory certification and a current, dated copy of normal range values. 
 
 
17. ETHICAL AND REGULATORY OBLIGATIONS 
17.1 Study Conduct 
The Investigator agrees that the study will be conducted according to the protocol, ICH Good 
Clinical Practice (GCP) and the ethical principles that have their origin in the Declaration of Helsinki.  
The Investigator will conduct all aspects of the study in accordance with applicable local law(s) and 
regulation(s). 
The Investigator will assure proper implementation and conduct of the study including those study-
related duties delegated to other appropriately qualified individuals.  The Investigator will assure that 
study staff cooperate with monitoring and audits. 
The Investigator must sign and return to the Sponsor the “Investigator Approval" page. 
 
 
17.2 Institutional Review Board  
Documented approval for conducting the study from the appropriate Institutional Review Board 
(IRB) will be obtained for all participating centers before initiation of the study, according to ICH GCP, 
applicable local law(s) and regulation(s).  When necessary, an extension, amendment or renewal of 
the IRB approval must be obtained and also forwarded to the Sponsor. 
 
A copy of written IRB approval or a favorable opinion of the protocol, informed consent form and 
subject recruitment material (if applicable) must be provided to the Sponsor before start of the study. 
The Investigator is responsible for obtaining from the IRB continued review of the clinical research 
or submitting periodic progress reports, in accordance with applicable regulations, at intervals not to 
exceed one year or as otherwise specified by the IRB.  The Sponsor must be supplied with written 
documentation of continued review of the clinical research.

Confidential and Proprietary :30 October 2015 
The Investigator must promptly inform the IRB of all SAEs reported by subjects enrolled in the 
study or other safety information reported from the Sponsor in accordance with applicable law(s) and 
regulation(s). 
 
17.3 Informed Consent 
The Investigator will prepare the informed consent form and provide the form to Sponsor for 
approval before submission to the IRB.  The informed consent form will be approved by the Sponsor 
before submission to the IRB.   
 
The Sponsor may provide a template informed consent form to be qualified by each research facility 
to conform to local requirements.  All informed consent forms must contain the minimum elements 
as mandated by ICH GCP, applicable local law(s) and regulations and will be approved by the Sponsor 
as well as the IRB. 
   
For patients who are under the adult age based on the local regulation in each country at informed 
consent, consent should be obtained from the patient’s legally acceptable representative (guardian) in 
addition to the consent from the patient. 
 
Before recruitment and enrollment, each prospective subject and guardian (as needed) will be given 
a full explanation of the study, allowed to read the approved informed consent form and be provided 
ample time and the opportunity to ask any questions that may arise.  Once all questions have been 
answered and the Investigator is assured that the prospective subject and guardian (as needed) 
understand the implications of participating in the study, the prospective subject and guardian (as 
needed) will be asked to give consent to participate in the study by signing the informed consent form.  
As part of the consent process, each prospective subject and guardian (as needed) must consent to 
direct access to his/her medical records for study-related monitoring, auditing, IRB review, and 
regulatory inspection.  It should be clearly explained to each prospective subject and guardian (as 
needed) that participation in each and every clinical visit and assessment is expected.  The subject 
may be discontinued from study medication, but that does not necessarily negate the expectation that 
the subject will continue to participate in the study through the final visit/assessment.  The 
Investigator will provide a copy of the signed informed consent form to each subject and guardian (as 
needed), and will record the date of the informed consent in the CRF.  
 
If an amendment to the protocol changes the subject participation schedule in scope or activity, or 
if important new information becomes available that may be relevant to the subject’s or guardian’s (as 
needed) consent, the informed consent form must be revised, submitted to the IRB for review and 
approval or a favorable opinion.  The revised informed consent form must be used to obtain consent 

Protocol No. D4904040 1.02 
DSP-5423P 
58 
 
Confidential and Proprietary :30 October 2015 
from a subject and guardian (as needed) currently enrolled in the study if he or she is affected by the 
amendment.  The revised informed consent form must be used to obtain consent from any new 
subjects who are enrolled into the study after the date of approval or a favorable opinion of the protocol 
amendment. 
 
17.4 Subject Privacy 
The Sponsor (or Sponsor’s representative) or any designees affirm uphold the subjects 
confidentiality.  The subject will be identified by a unique code only; full names will be masked 
before transmission to the Sponsor.  The confidentiality of the subject’s personal data shall be 
protected in accordance with appropriate laws and regulations.  When any formal presentation or 
publications of data collected as a direct or indirect result of the study are made, the subject privacy 
will be protected. 
 
17.5 Protocol amendments, Emergency deviations 
All revisions and/or amendments to this protocol must be approved in writing by the Sponsor and 
the appropriate IRB.  The Investigator will not make any changes to the conduct of the study or the 
protocol without first obtaining written approval from the Sponsor and the IRB, except where 
necessary to eliminate an apparent immediate hazard to a study subject. 
Emergency deviations or modifications may be initiated without Sponsor or IRB approval or a 
favorable opinion, only in cases where the deviation or modification is necessary to eliminate or avoid 
an immediate apparent hazard to subjects.  Emergency deviations or modifications must be reported 
to the Sponsor and the IRB immediately or in accordance with applicable regulatory requirements. 
 
17.6 Records Retention 
The Investigator/the site must arrange for retention of study records at the study center in accordance 
with applicable regulations and Sponsor SOPs.  The Investigator/site should take measures to prevent 
accidental or premature destruction of these documents.  Documents cannot be destroyed without 
written Sponsor authorization.  The Sponsor will inform the Investigator/the site when the 
destruction of documents is permitted. 
 
17.7 Inspection of Records 
In the event of an inspection, the Investigator agrees to allow the Sponsor, its representative and the

will be considered a joint publication by the coordinating investigators or the Investigators and the 
appropriate personnel of the Sponsor.  For multicenter studies, it is mandatory that the first 
publication is based on all data obtained from all analyses as stipulated in the protocol.  Investigators 
participating in multicenter studies must agree not to present data gathered individually or by a 
subgroup of centers before the full, initial publication, unless this has been agreed to by all other 
Investigators and by the Sponsor. 
 
17.9 Compensation 
If subjects have any adverse event or injury directly resulting from the study medications or 
procedures, the Sponsor will appropriately compensate in accordance with applicable 
regulatory requirements. However, excluding the cases a) to d) below. 
a) When the (causal) relationship between this study and the adverse event or injury is denied, 
it does not constitute a study subject of compensation. 
b) It shall not be a study subject of compensation in the event that adverse event or injury 
occurs due to participating medical institution or a reason attributable to the liability of a 
third party. 
c) If the expected effects of the drug or other benefits cannot be offered, it should not be a 
study subject of compensation. 
d) Damage to health due to intentional or serious negligence on the part of the subject may not 
be compensated or may be restrict.
