STUDY SUMMARY
Name of Sponsor:
Takeda Pharmaceutical Company Limited
Study Drug:
TAK-385
Study Title: A Phase 1, Open-label, Multicenter Study 
to Evaluate the Tolerability, Safety, Pharmacokinetics, 
and Pharmacodynamics of TAK-385 Alone in Hormone 
Treatment-naive Japanese Patients With Non-metastatic 
Prostate Cancer
IND Number:
NA
EudraCT Number:
NA
Study Number: TB-AK160108
Phase: 1
Study Design:
This study consists of two parts: Part A, a dose-rising phase, and Part B, an expansion phase.
In Part A, three to six patients will be enrolled in each cohort. Whether or not the study will proceed to the 
next cohort or Part B will be determined through assessment of tolerability at the dose in question, based on 
the incidence of dose-limiting toxicity (DLT) in the evaluation period. TAK-385 will be taken once a day 
for 28 days at the doses assigned to each cohort. Cohort 1 will receive a loading dose of 320 mg and a 
maintenance dose of 80 mg, Cohort 2 will receive a loading dose of 320 mg and a maintenance dose of 
120 mg, Cohort 3 will receive a loading dose of 320 mg and a maintenance dose of 160 mg, and Cohort 4
will receive a loading dose of 360 mg and a maintenance dose of 120 mg. Patients being switched to a 
gonadotropin-releasing hormone (GnRH) agonist (eg, leuprorelin) or a GnRH antagonist (eg, degarelix) 
following the completion of TAK-385 treatment in Part A will first pass through a 1-week observation 
period (except for study withdrawals). Whether or not the study will proceed to Part B will be determined 
by the study sponsor after consulting the study monitoring committee (SMC) based on a comprehensive 
evaluation of the tolerability and safety data from Cohort 2 of Part A.
In Part B, subjects will be randomized to receive study drug (TAK-385 loading dose of 320 mg and 
maintenance dose of either 80 mg or 120 mg – equal numbers of subjects will be randomized to 80 mg and 
120 mg) once a day orally to evaluate safety. In addition to the safety assessments, efficacy assessments 
will also be performed according to the study schedule, and study drug will be administered until the 
discontinuation criteria (Section 7.5) are met for each individual subject. After completing 48 weeks of 
treatment, subject may, at the discretion of the investigator, and depending on the wishes of the subject, 
continue receiving study drug (for a maximum of 96 weeks), or they may complete the study and be 
switched to a GnRH agonist or a GnHR antagonist, starting from the day after the day of the last dose of 
TAK-385.
All subjects who receive study drug will undergo safety follow-up 30 to 40 days after the last dose of 
TAK-385.
Part A (Dose-rising phase)
Primary Objectives:
To evaluate the tolerability and safety of TAK-385 in hormone treatment-naive patients with non-
metastatic prostate cancer.
Secondary Objectives:
To evaluate the pharmacokinetics (PK) and the effects on serum testosterone of TAK-385 in hormone 
treatment-naive patients with non-metastatic prostate cancer.
Part B (Expansion phase)
Primary Objectives:
To evaluate the safety of TAK-385 in hormone treatment-naive patients with non-metastatic prostate 
cancer.
Secondary Objectives:
To evaluate the change over time in the prostate-specific antigen (PSA) levels and the PK and effects on 
serum testosterone of TAK-385 in hormone treatment-naive patients with non-metastatic prostate cancer.

after treatment (eg, normal/abnormal, qualitative clinical laboratory test values) will be performed by part 
and dose for each test parameter.
Pharmacokinetic analyses
Pharmacokinetic parameters (eg, maximum observed plasma concentration [Cmax], area under the plasma 
concentration - time curve [AUC]) will be evaluated using the plasma TAK-385 concentrations, and 
summary statistics will be calculated for the plasma concentrations and each of the pharmacokinetic 
parameters. Figures showing the changes over time in the plasma concentration of TAK-385 will also be 
prepared.
Rationale for the Planned Sample Size
Part A
Each cohort will have 3 or 6 subjects, based on the the guidelines on the clinical evaluation of 
antineoplastics 
Part B
In order to detect less frequent AEs, 15 subjects per group (total of 30 subjects) were established as the 
number of cases enabling an approximately 80% chance of detecting AEs characterized by a true incidence 
of 10%.

INTRODUCTION
4.1
Summary
In 2008 prostate cancer reached approximately 900,000 cases/year worldwide and is now 
the second leading cancer in men, accounting for 13.7% of cancer cases in men [1]. The 
median age of diagnosis is 70, and prostate cancer is rarely diagnosed in men under 40 
[2]. Incidence increases with age and is expected to rise in the future as the population 
ages. In Japan, 2008 statistics show that prostate cancer ranks a high fourth in morbidity 
among cancers in men [3]. Prostate cancer in Japan also occurs more often with age, and 
the incidences increases rapidly in men 60 and older.
It is known that prostate cancer is to responsive to surgical castration and that the 
effectiveness of this therapy results from the elimination of androgen. This knowledge 
led to the understanding that most prostate cancers are growth hormone dependent and 
ever since this discovery, hormone therapy has played an important role in the treatment 
of prostate cancer.
Castration by orchiectomy or a gonadotropin-releasing hormone (GnRH) agonist is the 
main mode of therapy for localized progressive and metastatic cancers, and GnRH 
agonists such as leuprorelin acetate are widely used [4]. When multiple doses of a GnRH 
agonist are administered, a temporary increase in gonadotropin secretion (flare up) 
occurs. That is followed by a decrease in responsiveness (desensitization) in the pituitary 
gland and gonads, which appears to work effectively by inhibiting the secretion of sex 
hormones. The flare up sometimes leads to a temporary worsening of symptoms, and the 
effectiveness of GnRH agonist begins to appear about 3 to 4 weeks after the initial dose.  
In addition, the GnRH is a peptide formulation and is unable to be administered orally. 
Consequently, development of a new medication that is easy to administer and does not 
cause flare ups is needed.
TAK-385 is a non-peptide orally active GnRH antagonist with a novel structure that was 
discovered by Takeda Pharmaceutical Company, Ltd. TAK-385 antagonizes GnRH at 
the GnRH receptors present in the basophils (secreting cells) of the anterior pituitary 
gland and inhibits the GnRH-stimulated secretion of gonadotropin luteinizing hormone 
(LH) and follicle-stimulating hormone (FSH) from those cells. This action lowers the 
serum testosterone concentration in the blood. An antitumor effect is expected in prostate 
cancer patients due to the suppression of serum testosterone production by the testes. 
TAK-385 is also expected to manifest its effects rapidly without causing flare ups like 
GnRH agonists. Moreover, because it is a non-peptide formulation, TAK-385 can be 
administered orally, unlike peptide-based GnRH agonists that must be absorbed 
subcutaneously. The clinical pharmacokinetic and pharmacodynamic profiles may offer 
additional advantages compared with a depot peptide formulations, such as more rapid 
recovery from short term medical castration.
Takeda Pharmaceutical Co., Ltd. decided to develop TAK-385 for the treatment of 
prostate cancer both overseas and in Japan. Moreover, development of TAK-385 in 
Japan and Asia for endometriosis and uterine fibroids is already underway.

4.1.2.5
Overseas Phase 1 Single- and Multiple-dose Study (TAK-385_C27001)
Study C27001 was a phase 1 study that evaluated the safety, tolerability, PK, and PD of 
TAK-385 in 176 healthy English adult male subjects (128 subjects received TAK-385) 
receiving single doses of TAK-385 up to 360 mg QD and multiple doses of TAK-385 up 
to 180 mg QD for up to 28 days. The study had 4 parts: Part 1 included single-dose 
administration of TAK-385 to 32 subjects across 4 dose cohorts plus placebo and had a 
fed/fasted arm; Part 2 included multiple dose administration of TAK-385 for 14 days to 
40 subjects across 5 dose cohorts plus placebo; and Parts 3 and 4 included multiple dose 
administration of TAK-385 for 28 days to 66 and 38 subjects, respectively, across 2 dose 
cohorts (a total of 4 dose levels), plus placebo.
There were no deaths or SAEs following single-dose or multiple-dose treatment with 
TAK-385 for 14 or 28 days.
Following 28 days of QD dosing, there were 3 discontinuations due to drug-related, 
hepatic AEs: 2 subjects in the 160 mg dose cohort in Part 3 of the study discontinued 
treatment due to Grade 1 AEs of hepatic enzyme increased (ALT and AST); and 1 
subject in the 60 mg dose cohort in Part 4 of the study discontinued treatment due to a 
Grade 2 AE of liver function test (LFT) abnormal (ALT and AST). There was no clear 
trend between dose level and toxicity, although abnormal liver transaminase levels 
appeared more likely to occur within 2 weeks at higher dose levels. All AEs resolved by 
the end of the study.
The majority of subjects had at least 1 AE, but no increase in the incidence of AEs with 
increasing dose of TAK-385 was observed. The most common AEs observed across all 
dose cohorts were bradycardia, hot flush, and headache, and the most common, drug-
related AE was hot flush.
A number of cardiac AEs according to Common Terminology Criteria for Adverse 
Events (CTCAE) were reported, but for these subjects the ECG interpretation was 
considered to be not clinically significant by the investigator. These cardiac AEs 
included electrocardiogram QT prolonged (1 AE in Part 1, 4 AEs in Part 2, and 7 AEs in 
Part 3) and first degree atrioventricular block (2 AEs in Part 1 and 6 AEs in Part 2). 
Changes in mean QTc interval of approximately 15 to 20 msec were noted before 
administration on Day 14 (80 to 180 mg QD) in adult male subjects in this study. The 
QTc changes were independent of drug administration, not correlated to drug levels, and 
are similar to those observed in surgical and medical castration studies with other 


TAK-385

compounds. No major safety concerns were noted in healthy male subjects receiving 
single (80 to 360 mg) and multiple (20 to 180 mg) doses of TAK-385, and TAK-385 was 
well tolerated.
Single doses of 80 to 360 mg of TAK-385 administered orally (fasted state) were 
absorbed rapidly in plasma with median Tmax values ranging from 1.75 to 4.00 hours 
after administration across the entire dose range. After attaining Cmax, TAK-385 plasma 
concentrations declined in a multi-exponential manner with a mean T1/2 ranging from 
19.1 to 21.7 hours. The mean Cmax and AUC values for TAK-385 generally increased 
in an approximately dose-proportional manner over the 80 to 360 mg dose range.
When a multiple dose of 20 to 180 mg QD of TAK-385 was administered, the drug was 
readily absorbed in plasma on Days 1 and 14, and Cmax typically occurred within 1 to 2 
hours after dosing. After attaining Cmax, individual PK profiles on Day 14 exhibited a 
multi-exponential elimination phase with a mean elimination phase T1/2 of 
approximately 36 to 65 hours at doses of 20 to 180 mg QD. The trough concentration-
time data (Day 2, and Days 11 to 14) implied that steady-state conditions were attained 
within approximately 10 days.
Similarly, the effect of food was studied in 6 male subjects in the crossover period (Part 
1). Compared to fasting conditions, the absorption of TAK-385 in plasma decreased and 
was delayed following a single 180 mg dose taken 30 minutes after the start of a standard 
FDA high-fat, high-calorie breakfast. Least square mean Cmax and AUC(0-inf) values 
decreased by approximately 52% and 47%, respectively. Furthermore, median Tmax 
increased from 1.75 hours to 5.00 hours under fed conditions. When the dose was 
administered 30 minutes prior to the standardized morning meal (Part 2), systemic 
exposure to TAK-385 appeared to be reduced to a lesser extent (approximately 28% on 
average) and no changes in the absorption rate were observed.
In this study, serum LH, FSH, dihydrotestosterone (DHT), and testosterone 
concentrations were determined following single and multiple oral doses of TAK-385 or 
placebo for up to 28 days. TAK-385 caused an immediate and effective suppression of 
gonadotropins (LH, FSH) and testosterone. While no changes were observed in the 
placebo group, serum testosterone levels were markedly suppressed in all TAK-385 dose 
groups within the first 3 days of administration. Loading doses of 320/240/160 mg for up 
to 3 days and doses of 180 mg or greater led to testosterone levels below the conventional 
castration level within 48 hours. The onset of the testosterone lowering response 
shortened as the loading dose increased. This phenemon was likely a result of higher 
TAK-385concentrations in the blood. Similar dose-dependent suppressive effects were 
observed after a single oral dose. These findings support the principal mechanism of 
action that, as a GnRH antagonist, TAK-385 competitively binds with the pituitary GnRH 
receptors.
In administration over 28 days in Part 3 and 4, both 160 mg and 80 mg QD were effective 
at achieving conventional medical castration levels during the third and fourth weeks of 
multiple administration. Despite the loading dose regimen, however, the 40-mg QD dose 
was ineffective in maintaining castration levels between Days 14 and 28. The results at 
60 mg QD were intermediate to those of 40 and 80 mg QD and suggested that the likely

minimal, fully effective maintenance dose for medical castration would be 80 mg QD or 
above [5].

[5].
4.2
Rationale for the Proposed Study
The results of the phase 1 study conducted in England (TAK-385_C27001) demonstrate 
the tolerability of multiple doses of TAK-385 (20 to 80 mg) in healthy adult men. 
Moreover, the plasma concentration of TAK-385 increased as the dose increased, and 
rose slightly greater than dose proportionality. The blood concentrations of the measured 
hormones all decreased rapidly with multiple doses of TAK-385 and effective 
suppression of serum testosterone was sustained throughout the adminsitration period.
 
 
Because prostate cancer is a sex-hormone dependent disease, and an antitumor effect is 
expected as a result of lowering hormone concentrations in the blood through 
administration of TAK-385, it was decided to conduct a phase 1 study in patients with
prostate cancer.
This protocol was prepared in accordance with the Good Clinical Practice (GCP).

STUDY DESIGN AND DESCRIPTION
6.1
Study Design
This is a multicenter phase 1, open-label, dose range-finding study to evaluate the 
tolerability, safety, PK, and pharmacodynamics of TAK-385 alone in hormone treatment-
naive Japanese patients with non-metastatic prostate cancer.
This study consists of two parts: Part A, a dose-rising phase, and Part B, an expansion 
phase. The designs of Part A and Part B are shown in “Study Design and Treatment 
Schema” (Figure 6.a and Figure 6.b).
In Part A, three to six patients will be enrolled in each cohort. Whether or not the study 
will proceed to the next cohort or Part B will be determined through assessment of 
tolerability at the dose in question, based on the incidence of DLT in the evaluation
period (treatment initiation to Day 28).
TAK-385 will be taken once a day for 28 days at the doses assigned to each cohort. 
Cohort 1 will receive a loading dose of 320 mg and a maintenance dose of 80 mg, Cohort 
2 will receive a loading dose of 320 mg and a maintenance dose of 120 mg, Cohort 3 will 
receive a loading dose of 320 mg and a maintenance dose of 160 mg, and Cohort 4 will 
receive a loading dose of 360 mg and a maintenance dose of 120 mg. The doses will be 
taken orally at least 30 minutes before breakfast. Patients being switched to a GnRH 
agonist (eg, leuprorelin) or a GnRH antagonist (eg, degarelix) following the completion 
of TAK-385 treatment in Part A will first pass through a 1-week observation (no-
treatment) period. However, patients whose treatments were discontinued because they 
met the discontinuation criteria (Section 7.5) during the 28-day treatment period will not 
have to pass through this observation period.
If tolerability is confirmed in Cohort 2, then the study will proceed to Cohort 3 and Part B 
simultaneously. The tolerability in Japanese of the maximum dose at which tolerability 
was found in 28-day multiple dosing in the overseas phase 1 single-/multiple-dose study 
(TAK-385_C27001) (160 mg) will be evaluated for the purpose of checking the 
tolerability of dose escalation to 160 mg in Part B as well as the PK. In the overseas 
phase 1 single-/multiple-dose study (TAK-385_C27001), no findings indicative of safety 
problems were obtained in multiple dosing for 28 days with 160 mg. However, if 
tolerability is not confirmed in Cohort 2, then a cohort will be added that will receive a 
loading dose of TAK-385 320 mg and a maintenance dose of 40 mg.
Cohort 4 will be conducted after tolerability is confirmed in Cohort 2. Cohort 4 will be 
conducted for the purpose of evaluating the tolerability of 360 mg as loading dose in 
Japanese. 360 mg has been found tolerable in single dosing in the overseas phase 1 
single-/multiple-dose study (TAK-385_C27001) 
 
.
In Part B, subjects will be randomized to receive study drug (TAK-385 loading dose of 
320 mg and maintenance dose of either 80 mg or 120 mg – equal numbers of subjects 
will be randomized to 80 mg and 120 mg) once a day orally to evaluate safety. In 
addition to the safety assessments, efficacy assessments will also be performed according 


TAK-385 
TB-AK160108

to the study schedule, and study drug will be administered until the discontinuation 
criteria (Section 7.5) are met for each individual subject. After completing 48 weeks of 
treatment, subjects may, at the discretion of the investigator, and depending on the 
wished of the subhect, continue receiving study drug (for a maximum of 96 weeks), or 
they may complete the study and be switched to a GnRH agonist (eg, leuprorelin) or a 
GnHR antagonist (eg, degarelix), starting from the day after the day of the last dose of 
TAK-385. Subjects withdrawing from the study will not be replaced.
If no problems with tolerability are found in the additional cohort in Part A, then the 
study will proceed to Part B with a 40 mg group instead of a 120 mg group (TAK-385 
loading dose of 320 mg and maintenance dose of 40 mg).
All subjects who receive study drug, whether in Part A or Part B, will undergo safety 
follow-up 30 to 40 days after the last dose of TAK-385.
*1: If tolerability is not confirmed in Cohort 2, then a cohort will be added which will receive a loading 
dose of 320 mg and a maintenance dose of 40 mg.
*2: If a cohort is added, and the additional cohort continues to the end and no problems with tolerability are 
found, then the study will proceed to Part B.

6.1.1
Cohort/Part Advancement Criteria
Whether or not the study will proceed to the next cohort in Part A will be determined by 
the study sponsor after consulting the study monitoring committee (SMC) and following 
a comprehensive evaluation of the safety data based on the number of subjects 
experiencing DLT in each cohort (Table 6.c). Drug will be administered to the subjects 
in the next cohort after the decision on cohort advancement is made. See the separately 
prepared written procedures for detailed study advancement criteria.
In each cohort, if no DLT occurs in even 1 of the 3 subjects during the DLT evaluation 
period (see Section 6.1.2.2), then the dose will be judged tolerable, and the study will 
proceed to the next cohort. If a DLT occurs in 1 subject in the DLT evaluation period, 
and additional 3 subjects will be enrolled in this cohort, and DLT will be evaluated in a 
total of 6 subjects. If DLT occurs in 1 of these 6 subjects, this dose will be judged 
tolerable, and the study will proceed to the next cohort. If DLT occurs in 2 or more 
subjects, the study will be stopped, but if it is determined, after consulting the SMC, that 
this dose is tolerable, then the study will proceed to the next cohort.
Cohort 3, Cohort 4 and Part B will be conducted after tolerability is confirmed in Cohort 
2. Whether or not the study will proceed to Part B will be determined by the study 
sponsor after consulting the SMC based on a comprehensive evaluation of the tolerability 
and safety data from Cohort 2 of Part A.
If the study cannot proceed from Cohort 2 to Cohort 3 and Part B because of a tolerability 
problem, the study will proceed to an additional cohort that will receive a TAK-385 
loading dose of 320 mg and a maintenance dose of 40 mg. In this case, as well, 3 
subjects will be enrolled, and assessed in the same manner as described above. If the 
study proceeds to the additional cohort, and continues until the treatment of the additional 
cohort has been completed, and it is confirmed that no problems with tolerability are 
found, then the study will proceed to Part B.
If DLT occurs in 2 or more subjects in Cohort 3, then whether or not to increase the dose 
to 160 mg in Part B will be determined in consultation with the SMC.

Because assessment of the MTD is not the objective of this study, additional subjects will 
not be enrolled if TAK-385 is found to be tolerable in an evaluation of the 3 subjects in 
Cohort 3 or Cohort 4, nor will additional subjects be enrolled at lower dose levels if 
TAK-385 is not found to be tolerable at the dose level initially investigated.

Definition of DLT
DLTs are defined at treatment-related AEs that occur within the first 28 days of treatment 
and that meet one of the criteria described below based on CTCAE Version 4.03 (issued 
June 14, 2010) [13].

1.
Grade 3 or higher toxicity
Clinical laboratory abnormalities meet this criterion if they are found at 2 
consecutive time points 7 or more days apart, except for ALT or AST > 3 upper 
limit of normal(ULN), total bilirubin > 2 ULN, or prothrombin time-international 
normalized ratio (PT-INR) > 1.5 at 2 time points 2 or more days apart.
2.
Either of the following ECG findings at 2 time points 7 or more days apart
QT/Fridericia corrected QT (QTcF) > 500 msec after treatment initiation
QT/QTcF interval prolongation > 60 msec postdose
The QTcF interval will be calculated using Fridericia’s equation (QT/RR0.33).
If it is difficult to determine whether or not an event is a DLT and the subject who 
experienced the event should be included in the DLT analysis set, the sponsor will 
consult the SMC before making a final decision on whether or not the event is a DLT.
Study treatment will be continued until the end of the 28-day treatment period unless a 
DLT occurs. If a subject is withdrawn from the study for a reason other than a DLT or if 
treatment compliance is below 80% (23 doses), the subject will be considered ineligible 
for inclusion in the DLT analysis set, and replacement subjects will be added in order to 
obtain 3 or 6 evaluable subjects.
6.1.2.2
DLT Evaluation Period
From treatment initiation until Day 28 in Part A.
6.1.2.3
DLT Evaluable Subjects
Subjects meeting any of the following criteria enrolled in a cohort in Part A.

Subjects who have taken at least 80% of the doses of TAK-385 (23 doses) during the 
DLT evaluation period and for whom the DLT evaluation period observations have 
been completed.

Subjects who experienced DLTs during the DLT evaluation period.
6.2
Rationale for Study Design, Dosage, and Endpoints
(1) Rationale for the target patient population and the study design
The novel GnRH antagonist TAK-385 is expected to compensate for the deficiencies 
of the GnRH agonists that have been widely used in the treatment of prostate cancer 
to date, and is being developed as a novel therapeutic medication for prostate cancer. 
The target patient population for this study was therefore made Japanese patients 
with prostate cancer.
Because this study will be the first time in Japan that TAK-385 will be administered 
to patients with prostate cancer, and the safety and efficacy of TAK-385 for the 
target population have not been sufficiently demonstrated, the TAK-385 treatment 
period in Part A was set at 28 days. The treatment period would minimize the 


TAK-385 
TB-AK160108
Page 34 of 112
Amendment 2
1 July 2015
CONFIDENTIAL
inconvenience to subjects with safety concerns or insufficient efficacy. Because 
TAK-385 will be administered alone to hormone treatment-naive patients with 
prostate cancer, a placebo would not be used, and that the study would be conducted 
as an open-label study. It was also decided that if a subject is going to be switched to 
some other therapy after receiving the last dose of TAK-385 in Part A, then the 
patient would have to first pass through a 1-week observation (no-treatment) period 
because of concerns about the safety of the temporary concomitant use of TAK-385 
with other therapies. However, subjects meeting the discontinuation criteria (Section 
7.5) during the 28-day treatment period would not need to first pass through a 1-
week observation period if they need to be switched to some other therapy 
immediately.
The treatment period in Part B was made 48 weeks long in order to investigate safety 
and efficacy over a longer period, in light of the fact that the safety and efficacy of 
TAK-385 in multiple dosing for 28 days will have been confirmed in Part A. If the 
investigator or sub-investigator determines after 48 weeks that there are no safety 
problems and that TAK-385 treatment may be continued, then treatment may be 
continued for up to a total of 96 weeks. Part B was made an open-label phase with 
randomization to one of two doses the tolerability of which will have been confirmed 
in Part A. An open-label study design was used because TAK-385 is being 
administered alone to hormone treatment-naive patient with prostate cancer. In 
addition, if a subject is going to be switched to some other treatment after the last 
dose of TAK-385 then, unlike in Part A, and assuming use in the actual clinical 
setting, it was decided that the other therapy could be initiated without any 
intervening observation period for confirming the safety of temporary concomitant 
use with the other therapy.
Furthermore, TAK-385 has been found to be affected by food, and the results that 
have been obtained suggest that TAK-385 absorption is decreased and delayed when 
a single dose is taken 30 minutes after food compared to when it is taken in a fasted 
condition (TAK-385_C27001). It was therefore decided that TAK-385 should be 
taken at least 30 minutes before breakfast.
Because the company plans to participate in multinational studies in the future, it was 
decided that Part B would be conducted using the same dosage and administration as 
that being used in the phase 2 studies being conducted overseas. Because Part B will 
be conducted using a dosage the tolerability of which will have been confirmed in 
Cohorts 1 and 2 in Part A, it was decided that Part A Cohort 3 and Part B could be 
conducted in parallel.
(2) Rationale for loading dose (Part A, Cohort 1)
In a phase 1 study in healthy adult males that was conducted in Europe 
(TAK-385_C27001), the tolerability of single doses as high as 360 mg and multiple
doses as high as 160 mg was confirmed. In order to keep serum testosterone at 
castration levels and maintain this effect, it was felt that a dose of at least TAK-385 
80 mg a day would be necessary as a maintenance dose. In addition, in study 


TAK-385 
TB-AK160108
Page 35 of 112
Amendment 2
1 July 2015
CONFIDENTIAL
TAK-385_C27001, single doses of TAK-385 180 mg and above reduced serum 
testosterone levels to castration levels within 48 hours.
 
 
 
 
Based on these existing data on TAK-385 and on the development plan, it was 
decided that the loading dose for Cohort 1 in Part A of this study should be 320 mg, 
a dose that is within the range of doses that have been confirmed to be safe in single 
dosing, and that can be reliably expected to suppress serum testosterone levels within 
48 hours. Given that TAK-385 is going to be used in patients with prostate cancer, 
the company concluded that it would be necessary to use a dose that could be 
expected to be effective from the beginning, and that this dose would be tolerated as 
the loading dose in Japanese. The maintenance dose was set at 80 mg, which can be 
expected to suppress serum testosterone levels.
(3) Rationale for dosage in Part A, Cohort 4
320 mg or 360 mg may be selected as the loading dose in the planned phase 3 
multinational study. Based on this situation, a new cohort, Cohort 4, was added to 
Part A in Amendment 2 of the study protocol, designed to evaluate the tolerability of 
loading dose of 360 mg in Japanese patients before joining the phase 3 multinational 
study. As for the maintenance dose, the same dose as Part A, Cohort 2 (120 mg) was 
selected, since this dose is expected to keep serum testosterone at castration levels 
and maintain this effect.
As described in the section above, the tolerability of single doses of 360 mg and 
multiple doses as high as 160 mg (for 28 days) has been confirmed in a phase 1 study 
in healthy adult males that was conducted in Europe (TAK-385_C27001).
  Based on the fact that there are no major differences 
between Japanese and Americans in the pharmacokinetic or pharmacodynamic 
profiles of TAK-385, and that there are no major differences between the 
pharmacokinetic profiles obtained in healthy adult men and women, there are no 
safety concerns in using the loading dose of 360 mg and maintenance dose of 
120 mg in Part A, Cohort 4.
(4) Rationale for endpoints
1) Rationale for the primary endpoints


TAK-385 
TB-AK160108
Page 36 of 112
Amendment 2
1 July 2015
CONFIDENTIAL
The endpoint in Part A is DLT, in order to confirm the tolerability of TAK-385 in 
multiple dosing. AEs, clinical laboratory tests, vital signs, and 12-lead ECGs 
were also made primary endpoints, in order to confirm safety.
In part B, the primary endpoints were made AEs, clinical laboratory tests, vital 
signs, and 12-lead ECGs, in order to confirm the safety of the use of TAK-385 in 
multiple dosing for 48 weeks.
2) Rationale for secondary endpoints
In both Part A and Part B, the plasma concentrations of unchanged TAK-385 will 
be investigated in order to confirm the PK of TAK-385 in multiple dosing. The 
change in serum testosterone levels over time will also be investigated, in order to 
confirm the pharmacodynamics. In addition, in Part B, PSA levels will also be 
evaluated in order to investigate the efficacy of TAK-385 in prostate cancer.
3) Rationale for other endpoints
In Part A, the changes over time in the blood levels of LH, FSH, DHT, and 
SHBG, which are involved in testosterone synthesis, will be investigated. PSA 
levels will also be evaluated, in order to preliminarily investigate the efficacy of 
TAK-385 in prostate cancer.
In Part B, disease progression assessed on the basis of PSA and disease 
progression assessed on the basis of imaging assessments will be evaluated in 
accordance with the Prostate Cancer Handling Guidelines, Fourth Edition [16], in 
order to preliminarily investigate the efficacy of TAK-385 in prostate cancer. In 
addition, as in Part A, the changes over time in the blood levels of LH, FSH, 
DHT, and SHBG will also be investigated. Moreover, because androgen-
deprivation therapy is known to promote loss of bone mineral density and 
increase the potential for bone fractures, bone density tests were specified in order 
to evaluate the effects of TAK-385 on bone mineral density. In nonclinical 
studies, changes suggesting systemic phospholipidosis have been found in the 
organs/tissues of animals. Therefore, in order to closely monitor subjects for 
phospholipidosis, ophthalmology tests were specified, as was assessment of the 
level of di-docosahexaenoyl (22:6)-bis(monoacylglycero)phosphate (BMP) [14, 
15]. Furthermore, in order to evaluate the effects of TAK-385 on quality of life in 
patients with prostate cancer, quality of life assessments will be performed using 
the Japanese versions of AMS, EORTC-QLQ-C30, and EPIC, which are widely 
used in clinical studies overseas.

Food
From study treatment initiation and during the treatment period (in Part A, until the end

Subject Management
1. Inpatient/outpatient status
Subjects will be admitted to the investigational site from one day before treatment 
initiation in each cohort (Day -1) until Day 15 in Part A. As a rule, from Day 16 on, 
the study will be conducted on an outpatient basis until the safety follow-up. 
However, from Day 27 on, if a subject lives far from the hospital and it would be 
difficult for the subject to come to the hospital at the scheduled times, or if the subject 
desires admission, the study may be conducted on an inpatient basis from Day 27 
until Day 35 at the latest. While subjects are inpatients in Part A, they will eat meals 
(breakfast, lunch, and dinner) at specified times. After being discharged as well, 
subjects will be instructed to avoid eating or drinking excessively until the end of 
safety follow-up. When subjects are coming in for visits on an outpatient basis, they 
will be instructed to be sure to eat dinner on the day before the day of a visit at which 
a blood sample will be collected for laboratory testing, and they will be instructed to 
return to the hospital on the following day without eating for blood collection and 
testing, after which they will receive TAK-385 and then eat breakfast at least 30 
minutes later.
If a subject desires to return home temporarily during the inpatient period, and it 
would not interfere with study treatment, observations, or tests, then the investigator 
may allow the subject to return home temporarily, after carefully checking to be sure 
that the subject’s condition is stable, on the basis of the data that have been collected 
during the study to that point.
Unless there is a special reason, Part B will as a rule be conducted on an outpatient 
basis. Subjects will be instructed to observe the scheduled visit times and undergo 
the examinations and the specified tests. Subjects will also be instructed to inform 
the investigator promptly if they are not able to come in for a scheduled visit.
2. Study treatment
Investigators will instruct subjects to take the study drug 30 minutes before breakfast 
on each day, and to make sure that the time they take the study drug is the same on 
each day, to the extent possible.
If a subject forgets to take the study drug 30 minutes before breakfast, the subject 
should take the drug 30 minutes before lunch on the same day. If a subject forgets to
take the study drug both 30 minutes before breakfast and 30 minutes before lunch, the 
subject should take the study drug 30 minutes before dinner on the same day. It will 
be explained to subjects that they should not take any study drug that they have 
forgotten to take on a later day together with the study drug for that day. Subjects will

also be instructed to be sure to note in the patient diary the time they took the study 
drug as well as whether or not they took the study drug 30 minutes before breakfast.
On scheduled outpatient visit days, subjects will be asked to come to the 
investigational site in the morning without taking the study drug, and the scheduled 
tests will be performed.
3. Drinks, etc.
On days on which study drug is to be taken, subjects will be prohibited from drinking 
anything from 1 hour before dosing until 30 minutes after, other than one cup of 
water when they take the study drug.
4. Other
Investigators will instruct subjects that, if a subjective symptom emerges, it should be 
reported, along with the date of onset, severity, outcome, and date of outcome, when 
the subject next visits the investigational site.
Investigators will instruct subjects not to take any drugs, including over-the-counter 
drugs, other than the drugs that they are instructed to take, without consulting the 
investigator in advance.
Subjects will be instructed that, if they are treated at another medical institution in the
time between the treatment period and the safety follow-up, they are to report the 
background for and nature of said treatment to the investigator, and to inform the 
medical institution in question that they are participating in a clinical study.
7.5
Criteria for Discontinuation or Withdrawal of a Subject
Investigators will enter into the electronic case report form (eCRF) the primary reason for 
discontinuation or withdrawal of the subject from the study, classified into one of the 
following categories. See Section 9.1.23 for subjects discontinuing before the study 
treatment initiation (in the case of Part A) or before randomization (in the case of Part B).
1.
Pretreatment event or adverse event
This will be considered the primary reason if the subject has experienced a PTE or 
AE that requires early termination because continued participation imposes an 
unacceptable risk to the subject’s health or the subject is unwilling to continue 
because of the PTE or AE; if a serious AE occurs, the subject temporarily stops 
taking the study drug, and the AE recurs following study treatment resumption, or 
does not resolve event after 2 weeks of treatment interruption; or if toxicity that is 
considered DLT occurs in Part A.
Liver function test abnormalities
If a LFT abnormality meeting any of the following criteria occurs during study 
treatment, study drug administration will be discontinued immediately, and 
appropriate follow-up tests will be performed until the subject’s clinical laboratory 
profile returns to normal, to the level of the first test value obtained after informed

consent (in the case of a PTE), or to baseline (in the case of an AE) (see Section 
9.1.8).
-
ALT or AST > 3 ULN; AND total bilirubin > 2 ULN or PT-INR > 1.5
2.
Major protocol deviation
This will be considered the primary reason for study withdrawal if it is discovered 
after the first dose of study treatment (in the case of Part A) or after randomization 
(in the case of Part B) that the subject does not meet the enrollment criteria specified 
in the study protocol, or has not followed the study protocol, and that continuing the 
study would pose an unacceptable risk to the subject's health.
3.
Lost to Follow-up
This will be considered the primary reason for study withdrawal if a subject fails a 
study visit and cannot be contacted. In this case, the fact that contact was attempted 
will be noted in the source documents.
4.
Voluntary withdrawal
This will be considered the primary reason for withdrawal if the subject wishes to 
withdraw from the study. The reason for withdrawal, if provided, should be recorded 
in the eCRF.
Note: All attempts should be made to determine the underlying reason for the 
withdrawal and, where possible, the primary underlying reason should be recorded 
(ie, withdrawal due to an AE or lack of efficacy should not be recorded in the 
“voluntary withdrawal” category).
5.
Study termination
This will be considered the primary reason for withdrawal if the sponsor, IRB, or 
regulatory authorities decide to terminate the study.
6.
Lack of efficacy
This will be considered the primary reason for withdrawal if the expected level of 
efficacy is not obtained because of disease progression assessed by PSA level or 
evaluation of soft tissue or bone lesions by diagnostic imaging (according to the 
Prostate Cancer Handling Guidelines, Fourth Edition [16]), or if the decrease in 
serum testosterone meets any of the following criteria.
1) If, in Part A, serum testosterone does not drop below 50 ng/dL at 2 or more time 
points at least 7 days apart following treatment initiation, and it is determined as 
a result that the patient must be switched to some other therapy.
2) If, in Part B, serum testosterone does not drop below 50 ng/dL by 4 weeks after 
uptitration based on the uptitration criteria (see Section 8.1.3.1).
3) If, in Part B, serum testosterone exceeds 50 ng/dL on 2 consecutive occasions, or 
on 3 occasions in total, whether consecutive or not, by 9 weeks (57 days) after 
the start of treatment following uptitration in accordance with the uptitration 
guidelines (see Section 8.1.3.1).

Procedures for Discontinuation or Withdrawal of a Subject
If a subject meets the criteria described in Section 7.5, the investigator will withdraw the 
subject from the study. Furthermore, subjects may withdraw from the study without 
providing a reason at any time during the study. If a subject withdraws from the study, 
the investigator will enter the primary reason for withdrawal in the eCRF, and will 
perform all procedures scheduled for the Early Termination Visit.

*3: Treatment may be continued for up to 96 weeks in total
The specified dose of TAK-385 will be taken once a day orally with 1 cup of water at 
least 30 minutes before breakfast. Except for when various tests are being performed or 
an AE occurs, an effort will be made to ensure that subjects rest for 2 hours after 
receiving the dose.
The investigator or study support staff will check to make sure that all specified study 
drug has been taken.
8.1.3.1
Criteria for Upward Dose Adjustments
Part A: The dose of TAK-385 will not be increased even if inadequate testosterone 
suppression occurs (< 50 ng/dL). If after treatment initiation the serum testosterone level 
does not drop below 50 ng/dL at 2 or more time points separated by at least 7 days and 
the investigator or sub-investigator determines that the patient needs to be switched to 
some other treatment, then TAK-385 treatment will be stopped and the patient withdrawn 
from the study.


TAK-385 
TB-AK160108

Amendment 2
1 July 2015
CONFIDENTIAL
Part B: If the following conditions are met, the dose may be adjusted, taking efficacy and 
safety into consideration. Dose adjustment will be performed when the subject is 
examined by the investigator or sub-investigator.
If the serum testosterone level in an individual patient exceeds 50 ng/dL at Week 5 (Day 
29), Week 9 (Day 57), or Week 13 (Day 85), following review of compliance, a one-time 
upward dose modification (increment of 40 mg daily) will be allowed. After Week 13, 
the dose will not be increased even if the serum testosterone level exceeds 50 ng/dL.
The dose will not be increased in the 120 mg group before the DLT evaluations have 
been completed for Cohort 3 in Part A, or if the dose has not been found to be tolerable. 
Similarly, if tolerability is not found in Cohort 2 in Part A and a 40 mg group is therefore 
going to be used instead of a 120 mg group, then the dose in the 80 mg group will not be 
increased.
8.1.3.2
Criteria for Dose Holds and Dose Reduction
Part A: If a treatment-related AE occurs, or if it would be difficult to continue with TAK-
385 treatment, then the dose of TAK-385 will not be reduced, and study treatment will be
interrupted if necessary.
Part B: If a treatment-related AE occurs or if it would be difficult to continue with TAK-
385 treatment, then study treatment will be interrupted if necessary. Subjects who 
experience serious AEs requiring study treatment interruption within 12 weeks (84 days) 
following treatment initiation may have their doses reduced by one dose level – 40 mg –
following a 2-week treatment interruption period. If the AE continues even after dose 
reduction, or the subject’s serum testosterone level exceeds 50 ng/dL for 4 to 6 weeks 
following dose reduction, then TAK-385 treatment will be discontinued so that the 
subject may receive some other therapy. If a serious AE requiring study treatment 
interruption occurs on or after Week 13 (Day 85) following treatment initiation, and the 
subject’s treatment has not been interrupted prior to that, then the subject’s treatment may 
be interrupted for 2 weeks and then resumed. However, if the AE recurs following study 
treatment resumption, or if the AE does not resolve even after 2 weeks of treatment 
interruption, then the subject will be withdrawn from the study.
Even if the dose has been increased in accordance with Section 8.1.3.1, when reducing 
the dose, it will be reduced by one dose level. Dose reduction will not be performed for 
subjects in the 40 mg group. In addition, if the dose is reduced in accordance with this 
section, then the dose may not be increased as described in Section 8.1.3.1.
Furthermore, if a LFT abnormality is found, it will be handled as shown in Table 8.c.

Overdose
An overdose is defined as a known deliberate or accidental administration of 
investigational drug, to or by a study subject, at a dose above that which is assigned to 
that individual subject according to the study protocol.
All cases of overdose (with or without associated AEs) will be documented on an 
Overdose page of the eCRF, in order to capture this important safety information 
consistently in the database. Cases of overdose without manifested signs or symptoms are 
not considered AEs. AEs associated with an overdose will be documented on AE CRF(s) 
according to Section 10.0.
Serious AEs associated with overdose should be reported according to the procedures 
outlined in Section 10.2.2.
In the event of a study drug overdose, the investigator will treat the subject 
symptomatically.

8.2
Study Drug Allocation and Prescribing Procedures
In Part A, in order to confirm eligibility for study participation based on the screening 
tests, the investigator or a person designated by the investigator will contact the 
registration center by fax. The investigator will prescribe study drug to the subject after 
confirming that the subject is eligible for the study based on a fax received from the 
registration center.
In Part B, the investigator or a person designated by the investigator will contact the 
registration center by fax to confirm the subject’s eligibility at the start of the treatment 
period.  After confirming, on the basis of a fax received from the registration center, that 
the subject is eligible, the investigator will prescribe the subject the study drug for the 
group to which the subject has been assigned. The investigator or a person designated by 
the investigator will enter the group to which the subject has been assigned in the eCRF.
Subjects will be assigned a 4-digit number, with the first signifying the Part and Cohort, 
the second signifying the investigational site, and the last two digits constituting a series 
number within the cohort at the investigational site. This 4-digit number will be used by 
the investigational sites to identify the specimens that will be used to assess the PK and 
pharmacodynamics. These numbers will be noted on the specimen tubes that are 
provided for measurement, and will be used instead of the subject identification numbers 
for reporting the measurement results. These numbers will not be replaced by the last 3 
digits of the subject identification numbers.
8.3
Randomization Code Creation and Storage
The randomization manager (or a person designated by the study sponsor) will prepare a 
randomization table. The randomization information will be stored in a safe location, and 
will only be accessible to authorized personnel.
8.4
Control and Disposal of Drugs Provided by the Study Sponsor
The study drug controller will receive the written procedures prepared by the study 
sponsor specifying the handling, storage, and control of study drug, and will 
appropriately control the drugs provided by the study sponsor in accordance with these 
written procedures. The investigators will also receive these procedures from the study 
sponsor. These procedures will describe the procedures that will have to be followed to 
ensure that the receipt, handling, storage, control, and prescribing of the study drugs 
provided by the study sponsor, as well as the recovery of unused drugs from subjects and 
their return to the study sponsor, or their disposal, are carried out appropriately and 
reliably.
The study drug controlled will promptly return to the study sponsor any unused drugs 
once the study has been completed at the investigational site in question.

Study Proceduress
The following sections describe the study procedures and data to be collected. In 
principle, the same investigator will perform examinations and testing, observations, and 
evaluations of subjects. The Schedule of Study Procedures is shown in Appendix A to 
Appendix E.
9.1.1
Informed Consent
The requirements of the informed consent are described in Section 15.2.
Informed consent must be obtained from the subject before any protocol-directed 
procedures are performed.
A unique subject identification number will be assigned to each subject at the time that 
informed consent is explained. The same subject number will be used throughout the 
study.
Informed Consent for Pharmacogenomics
Informed consent for the storage and banking of the blood sample for pharmacogenomics 
(PGx) testing in this study must be obtained separately before collection. The provision 
of consent to collect and analyze the PGx sample is independent of consent to the other 
aspects of the study.
9.1.2
Demographics, Medical History, and Treatment History
Demographic data will include date of birth, sex, and smoking history at screening. The 
items listed below will be checked with regard to prostate cancer [16]. The findings will 
be input to the eCRF.

informed consent. If a symptom or disease is still present, it will be considered a 
comorbidity (concurrent medical condition) (see Section 9.1.18).
Previous therapeutic drugs used (medication history) will include all drugs that were 
discontinued within 28 days before the date of informed consent and are relevant to the 
eligibility criteria.
9.1.3
Physical Examination
A physical examination will be conducted for the parts of the body listed below 
(interview, visual inspection, auscultation, palpation, percussion, etc.).
(1) eyes, (2) ears, nose, and throat, (3) cardiovascular system, (4) respiratory organs, 
(5) digestive organs, (6) skin, (7) extremities, (8) musculoskeletal system, (9) nervous 
system, (10) lymph nodes, (11) urogenital organs, (12) other
The investigator will evaluate abnormal findings discovered in the pre-administration 
physical examination for clinical relevance and record the results in the source data. 
Findings and changes considered to be clinically relevant will be input as PTEs or 
comorbidities at the proper locations in the source data and eCRF as described in 
Sections 10.0 and 9.1.18.
9.1.4
Weight, Height, and ECOG Performance Status
Weight and height will be measured. Weight will be measured in kilograms to the first 
decimal place, and height will be measured in centimeters to the closest integer. In 
addition, the ECOG performance status will be measured in accordance with Appendix 
G.
9.1.5
Vital Signs
Measurement of vital signs will include temperature (axillary), seated blood pressure 
(systolic and diastolic after resting at least 5 min) and heart rate (bpm). Measurements 
will be taken after the subject has been sitting for 5 min.
9.1.6
Electrocardiogram
A 12-lead ECG will be performed. Measurements will be taken after the subject has been 
in supine position for 5 min. The investigator (or a specialist at the medical institution)
will assess the results by the following categories: Normal range ("Within Normal 
Limits"), Abnormal but not clinically significant ("Abnormal, Not Clinically Significant
"), or Abnormal and clinically significant ("Clinically Significant ").
The following parameters will be transferred from the subject's ECG recording to the 
eCRF: heart rate, QT interval, PR interval, QRS duration, and RR interval.
In determining the QTc value, Bazett corrected QT (QTcB) and QTcF will be calculated 
using the Bazett formula (QT/RR0.5) and Fridericia formula (QT/RR0.33), respectively.

Imaging Assessment
CT or MRI (thoracic, abdominal, and pelvic regions) and bone scintigraphy will be 
performed during screening to verify that there are no distant metastatic lesions. If 
measurements were taken within 28 days before the start of study drug administration, 
the results of diagnostic imaging and tests conducted before obtaining informed consent 
can be used. CT or MRI and bone scintigraphy will also be performed on the days 
stipulated in the clinical trial schedule (Appendix A to Appendix C) to check for new 
lesions. Disease progression will be determined by the presence or absence of new 
lesions based on the items evaluated in diagnostic imaging. Diagnostic imaging will also 
be performed as needed in Part A if abnormal findings appear in other tests and 
examinations during administration of the study drug.
9.1.8
Clinical Laboratory Tests
Specimens will be handled according to the procedures described in a separate document. 
A general guideline for the total amount of blood to be collected in this study is shown in 
Section 9.5.
Samples for clinical laboratory tests will be collected after at least 10 hours of fasting on 
the days stipulated in the Schedule of Study Procedures (Appendix A to Appendix E).

CK-MB and cardiac troponin T will be measured at the institution during screening. 
These measurements will also be performed as needed when abnormal findings appear in 
other tests and examinations during administration of the study drug.
9.1.10
Tumor Marker
PSA will be measured by a third-party organization according to a separately prepared 
written procedure. Progression of disease as indicated by PSA (based on the Prostate 
Cancer Handling Guidelines, 4th Edition [16]) is defined as an increase of at least 25% in 
the PSA value measured at least 4 weeks after the minimum PSA value measured during 
the study period (at least 12 weeks if the minimum value was recorded during screening). 
In such a case, the amount of increase must be at least 2 ng/mL. The date this condition 
is met will be considered the disease progression date.
9.1.11
Collection of Pharmacogenomic Sample
After the start of study drug administration (Part A) or after randomization (Part B), one 
sample for PGx testing will be collected as early as possible during the administration 
period. A sample of 5 mL of whole blood for DNA extraction will be collected in an 
EDTA-treated polypropylene tube from each subject who has given consent. The sample 
will be sent to the sample storage facility.
Details of collection, handling, and storage of the sample for PGx testing will be carried 
out according to a separately prepared written procedure.

Bone Mineral Density (Part B Only)
Bone mineral density will be measured by dual-energy X-ray absorptiometry (DXA). 
Throughout the study period the same subject will be measured on the same model of 
equipment using the same scanning mode. The investigator will input the equipment 
model, date of measurement, and results for the following measurement parameters into 
the eCRF.
Measurement sites: Lumbar 2 to 4 (L2 to L4) and hip (femoral neck, femoral 
trochanteric, femoral intertrochanteric, Ward's triangle, and total)
Measurement parameters: Bone mineral content (BMC, g), bone area (Area, cm2), and 
bone mineral density (BMD, g/cm2) of L2, L3, and L4, femoral neck, femoral 
trochanteric, and femoral intertrochanteric regions, and Ward's triangle; and total bone 
mineral content (BMC, g) (combined), bone area (Area, cm2) (combined), and bone 
mineral density (BMD g/cm2) (Mean) of L2 to L4 and hip.
9.1.13
Ophthalmological Examination (Part B Only)
The examination will be carried out in a darkened room. A slit lamp microscope will be 
used to examine the anterior of the eye, and the results will be classified as follows: 
Normal range, Abnormal but not clinically significant, or Abnormal and clinically 
significant.
9.1.14
BMP Concentrations (Part B Only)
BMP will be measured in serum and urine samples by a third-party organization 
according to a separately prepared written procedure. Sequential BMP testing will not be 
performed, and the measurements will be summarized after a fixed time period.  
Measurements will be conducted when there are clinical findings suggesting an 
association with phospholipidosis or there is a report of an association between 
comparable GnRH antagonists and phospholipidosis.
9.1.15
QOL Assessment (Part B Only)
QOL will be assessed using AMS, EORTC-QLQ-C30, and EPIC scores. After arriving 
at the hospital each subject will personally fill in the form provided by the sponsor before 
other tests are conducted and before the study drug is administered. The scoring of QOL 
will be carried out in the order: AMS, EORTC-QLQ-C30, and EPIC.
9.1.16
Concomitant Medications
The term concomitant medication is refers to any drug given in addition to the study 
drug. These may be prescribed by a physician or obtained by the subject over the 
counter. At each study visit, subjects will be asked whether they have taken any 
medication other than the study drug (used from signing of informed consent through
safety follow-up), and all medication including vitamin supplements, over-the-counter 
medications, and oral herbal preparations, must be recorded in the eCRF.

Concomitant Therapies
The term concomitant therapy refers to a medical act carried out for a therapeutic 
purpose. At each study visit, subjects will be asked whether they have received any 
therapeutic procedures (performed from signing of informed consent through safety 
follow-up).
9.1.18
Concurrent Medical Conditions
Concurrent medical conditions are those significant ongoing conditions or diseases that 
are present at signing of informed consent. This includes clinically significant laboratory, 
ECG, or physical examination abnormalities noted at screening examinations. The 
details of the condition (ie., diagnosis) should be recorded in the eCRF.
9.1.19
Contraception
Male subjects with female partners who may become pregnant will use a barrier-type 
contraceptive device (eg, condom and spermicidal cream or jelly) from the time of 
informed consent until 4 months after the final dose of the study drug. Furthermore, the 
subject will be instructed not to donate sperm during this time frame.
9.1.20
Pregnancy
If the subject's female partner becomes pregnant, the investigator, with the female 
partner's consent, will inform her attending physician (obstetrician) that the subject was 
participating in a clinical study when she became pregnant and reveal the details of the 
study drug.
If a pregnancy is reported for any subject, the investigator, with the subject's consent, will 
carry out a follow-up investigation until delivery, including premature delivery, and make 
a report to the sponsor using the designated follow-up form. The investigator will also 
conduct a postnatal evaluation.
9.1.21
Pharmacokinetic Assessments
The plasma concentrations will be measured at each blood sample collection time point 
(see Appendix D and Appendix E) in accordance with separately prepared written 
procedures.
The 3 time points for TAK-385 dosing that immediately precede blood sample collection, 
and the time points for the collection of blood samples for pharmacokinetic assessment, 
will be entered into the eCRF.
9.1.22
Pharmacodynamic Assessments
Serum testosterone, LH, FSH, DHT, and SHBG will be measured by an external 
measurement facility in accordance with separately prepared written procedures. Serum 
testosterone will be measured along with other highly sensitive measurements at

Monitoring Subject Treatment Compliance
During the inpatient period in Part A, the investigator or a person designated by the 
investigator will give the subject the study drug, confirm that the subject has taken it, and 
record this in the source documents. For study drug administration following discharge 
from the investigational site, subjects will be instructed to take the drug appropriately.
On the day of the first dose in Part B, the investigator or a person designated by the 
investigator will administer the study drug to the subject, confirm that the subject has 
taken the drug, and record this in the source documents. For study drug administration 
from Day 2 on, subjects will be instructed to take the drug appropriately.
The day of treatment initiation, the day of treatment completion, the dose, the actions 
taken with respect to the dose, and the reasons for any changes will be entered in both the 
source documents and the eCRF.

period and the continuation treatment period (Part B).
9.4
Biological Sample Storage and Disposal
The 5 mL samples of whole blood collected for PGx research will be stored frozen at the 
sample storage facility (Protocol Annex 1).
The storage period will be 20 years from the day the samples for PGx research were 
initially collected in this study.
During the sample storage period, if a subject wants his samples destroyed, the 
investigational site will ask, via the study sponsor, and in accordance with the specified 
procedures, the sample storage facility to destroy the subject’s samples. The sample 
storage facility will destroy the samples in questions in accordance with the procedures, 
and will inform the investigational site and the study sponsor that the samples have been 
destroyed. However, if the data that allow the subject to be identified (eg, medical 
records) have been destroyed once the study has been completed, and it is therefore no 
longer possible to link the subject to his samples, then the samples will not be destroyed.
Even if the samples can be tied to the subject, if the PGx investigation has already been 
performed, the remaining samples will be destroyed, but the anonymized results of the 
PGx investigation will be retained by the study sponsor.
The study sponsor will construct the administrative structure necessary to protect 
subjects’ personal information, and will stipulate in advance criteria for handling sample 
collection, storage, and disposal, as well as prepare the necessary written procedures.

PRETREATMENT EVENTS AND ADVERSE EVENTS
10.1
Definition
10.1.1
Pretreatment Events
A PTE is defined as any untoward medical occurrence in a clinical investigation subject 
who has signed informed consent to participate in a study but prior to administration of 
any study drug; it does not necessarily have to have a causal relationship with study 
participation.
10.1.2
Adverse Events
An AE is defined as any untoward medical occurrence in a clinical investigation subject 
administered a drug (including study drug); it does not necessarily have to have a causal 
relationship with this treatment.
An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant 
abnormal laboratory finding), symptom, or disease temporally associated with the use of 
a drug whether or not it is considered related to the drug.
10.1.3
Additional Points to Consider for Pretreatment Events and Adverse Events
An untoward findings generally may:

Indicate a new diagnosis or unexpected worsening of a pre-existing condition.
(Intermittent events for pre-existing conditions underlying disease should not be 
considered PTEs or AEs.)

Require therapeutic intervention

Require an invasive diagnostic procedure

Require discontinuation or a change in dose of study drug or concomitant medication

Be considered unfavorable by the investigator for any reason.
Diagnosis vs signs and symptoms:
Each event should be recorded to represent a single diagnosis. Accompanying signs 
(including abnormal laboratory values or ECG findings) or symptoms should NOT be 
recorded as additional AEs. If a diagnosis is unknown, sign(s) and/or symptom(s) should 
be recorded appropriately as a PTE(s) or as an AE(s).
Laboratory values and ECG findings:
Change in laboratory value or ECG parameters are only considered to be PTEs or AEs if 
they are judged to be clinically significant (ie., if some action or intervention is required, 
or if the investigators judges the change to be beyond the normal physiological 
fluctuation). A laboratory re-test and/or continued monitoring of an abnormal value are
not considered an intervention. In addition, repeated or additional noninvasive testing for 
verification, evaluation, or monitoring of an abnormality is not considered an 
intervention.


TAK-385 
TB-AK160108
Page 68 of 112
Amendment 2
1 July 2015
CONFIDENTIAL
If abnormal laboratory values or ECG findings are the result of pathology for which 
there is an overall diagnosis (eg, increased creatinine in renal impairment), the diagnosis 
only should be reported appropriately as a PTE or as an AE.
Pre-existing conditions (disease or symptoms existing before informed consent is 
obtained):
Pre-existing conditions (present at the time of signing of informed consent) are 
considered concurrent medical conditions and should NOT be recorded as PTEs or AEs. 
Abnormalities found in initial tests and observations (eg, laboratory tests, ECG, and 
radiology) after informed consent should NOT be recorded as PTEs unless related to 
study procedures, except that abnormalities occurring as a result of initial test or 
observation procedures (such as internal bleeding during blood draw) will be recorded as 
PTEs in the eCRF. If the subject experiences a worsening or complication of such a 
concurrent condition, the worsening or complication should be recorded appropriately as 
a PTE (worsening or complication occurs before start of study drug) or an AE (worsening 
or complication occurs after start of study drug). Investigators should ensure that the 
event term recorded captures the change in the condition (eg, "worsening of 
hypertension").
If a subject has a pre-existing episodic condition (eg, asthma, epilepsy) that increase in 
frequency or become serious or severe should be recorded as PTEs/AEs. Symptoms that 
worsen more than expected in subjects with chronic disease (eg, cataracts, rheumatoid 
arthritis) should also be recorded as PTEs/AEs. Investigators should ensure that the AE 
term recorded captures the changes in the condition from Baseline (eg, "worsening of 
XX").
Worsening of PTEs or AEs:
If the subject experiences a worsening or complication of a PTE after starting 
administration of the study drug or experiences signs/symptoms that occur secondarily to 
PTEs, the worsening or complication should be recorded appropriately as an AEs in the 
eCRF. Investigators should ensure that the AE term recorded captures the change in the 
condition (eg, "worsening of XX").
If the subject experiences a worsening or complication of an AE after any change in 
study drug, the worsening or complication should be recorded as a new AE in the eCRF. 
Investigators should ensure that the AE term recorded captures the change in the 
condition (eg, "worsening of XX").
Underlying disease:
In this study, worsening of the underlying disease will not be handled as an AE. The 
onset or worsening of symptoms associated with progression of the underlying disease 
will be handled as an AE.
Planned surgeries or procedures:
Preplanned procedures (surgelies or therapies) that were scheduled prior to signing of 
informed consent were not considered PTEs or AEs, except that any conditions and 
events associated with the worsening of pre-existing conditions requiring those 
procedures to be undertaken on an emergency basis should be captured appropriately as a 


TAK-385 
TB-AK160108
Page 69 of 112
Amendment 2
1 July 2015
CONFIDENTIAL
PTE or an AE. Complications resulting from any planned surgery should be reported as 
AEs.
Elective surgeries or procedures:
Elective procedures performed where there is no change in the subject's medical 
condition should not be recorded as PTEs or AEs, but should be documented in the 
subject's source documents. Complications resulting from an elective surgery should be 
reported as AEs.
Insufficient clinical response (lack of efficacy):
Insufficient clinical response, efficacy, or pharmacological effect should NOT be 
recorded as an AE. Investigators must make a distinction between worsening of 
pre-existing symptoms and lack of efficacy.
Overdose:
Cases of overdose with any medication without manifested side effects are NOT 
considered PTEs or AEs, but overdoses will be recorded on an overdose page of the 
eCRF.  Any manifested side effects will be considered AEs and will be recorded on the 
AE page of the eCRF.
10.1.4
Serious Adverse Events
A serious AE is defined as any untoward medical occurrence that at any dose:
1.
Results in DEATH.
2.
Is LIFE-THREATENING*.
3.
Requires inpatient HOSPITALIZATION or prolongation of existing 
hospitalization.
4.
Results in persistent or significant DISABILITY/INCAPACITY.
5.
Leads to a CONGENITAL ANOMALY/BIRTH DEFECT.
6.
Is an IMPORTANT MEDICAL EVENT that satisfies any of the following:
•
May require intervention to prevent items 1 through 5 above.
•
May expose the subject to danger, even though the event is not immediately 
life threatening or fatal or does not result in hospitalization.
•
Includes any event or synonym described in the Takeda Medically Significant 
AE List (Table 10.a).
* The term "life threatening" refers to an event in which the subject is at risk of death at the time of the 
event; it does not refer to an event that hypothetically might have caused death if it was more severe.

Acute renal failure
Pulmonary hypertension
Pulmonary fibrosis (including interstitial lung 
disease)
Neuroleptic malignant syndrome/malignant 
hyperthermia
Spontaneous abortion/stillbirth and fetal death
Confirmed or suspected transmission of infectious 
agent by drugs
Confirmed or suspected endotoxic shock
PTEs that fulfill 1 or more of the serious criteria above are also to be considered SAEs 
and should be reported by the same procedures as for SAEs (see Sections 10.2.2 and 
10.3).
10.1.5
Special Interest Adverse Events
A special interest AE (whether serious or not) is one of specific and medical concern 
specific to the study drug or program. Investigators will monitor subjects on an ongoing 
basis for such events, and the sponsor will be notified immediately of any that occur. 
Further investigation may sometimes be necessary to establish assessment of these 
events. Refer to Section 10.2.1.3 for the methods and deadlines for reports to the sponsor 
by investigators.
10.1.5.1
Liver Function Test Abnormalities
LFT abnormalities were identified as specific AEs because nonclinical studies in 
monkeys revealed LFT abnormalities and because clinical studies on oral GnRH 
antagonists with the same backbone structure as TAK-385 have revealed elevated AST 
and ALT as common treatment-related AEs.
The management of LFT abnormality AEs is presented in Table 8.c of the protocol.
When ALT or AST levels are > 3 ULN, retesting will be performed within 48 to 72 
hours (within 7 days at the latest). As soon as they become aware that ALT or AST 
levels are > 3 ULN, investigators will discuss detailed information on affected subjects 
and other potential causes with the sponsor to review whether the administration of study 
drug should be discontinued immediately.
If ALT or AST levels are > 3 ULN and total bilirubin levels are > 2 ULN or the PT-
INR is > 1.5, and investigators conclude that the levels cannot be explained by any factor 
other that study drug based on the results of retesting, then they will be handled as serious 
AEs.

When LFT abnormalities correspond to the criteria in Section 7.5, investigators will 
immediately discontinue administration of study drug and will perform appropriate 
follow-up.
10.1.6
Severity of Pretreatment Events and Adverse Events
The severity of AEs, including laboratory abnormalities, will be determined according to 
the CTCAE. Events not covered in the CTCAE will be classified and defined as follows.
Grade 1
Mild;*1 asymptomatic or mild symptoms; clinical or diagnostic observations only; 
intervention not indicated
Grade 2
Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate 
instrumental ADL*2
Grade 3
Severe or medically significant but not immediately life-threatening; hospitalization or 
prolongation of hospitalization indicated; disabling; limited self care ADL*3
Grade 4
Life-threatening consequences; urgent intervention indicated
Grade 5
Death related to AE
*1: A semi-colon indicates 'or' within the description of the grade.
*2: Instrumental ADL refer to preparing meals, shopping for groceries or clothes, using the telephone, 
managing money, etc.
*3: Self care ADL refer to bathing, dressing and undressing, feeding self, using the toilet, taking 
medications, and not bedridden.
AEs that undergo a change in severity for the worse will be individually recorded in the 
eCRF as separate AEs.
Clarification should be made between a serious AE and an AE that is considered severe 
in intensity (Grade 3 or 4), because the terms serious and severe are NOT synonymous. 
The term "severe" is often used to describe the intensity (severity) of a specific event, but 
the event itself may be of relatively minor medical significance (such as a Grade 3 
headache). This is NOT the same as "serious." For example, a white blood cell count of 
1000 to 2000/mm3 is considered Grade 3 (severe) but may not necessarily be considered 
serious. Seriousness (not intensity) serves as a guide for defining regulatory reporting 
obligations.
10.1.7
Causality of Adverse Events
The relationships of each AEs to study drug will be assessed using the following 
categories:
Related
An AE that follows a reasonable temporal sequence from administration of a drug (including 
the course after withdrawal of the drug), or for which possible involvement of the drug can 
be argued, although factors other than the drug, such as underlying diseases, complications, 
concomitant medications and concomitant therapies, may also be responsible.
Not related
An AE that does not follow a reasonable temporal sequence from administration of a drug 
and/or that can reasonably be explained by other factors, such as underlying diseases, 
complications, concomitant medications and concomitant therapies.

10.1.8
Relationship to Study Procedures
The relationship should be assessed as Related if the investigator considers that there is 
reasonable possibility that an event is due to a study procedure. Otherwise, the 
relationship should be assessed as Not Related.
10.1.9
Date of Onset
The date of AE onset (the start date of the AE/PTE) will be determined based on the 
following criteria.
AEs
Date of onset
Signs, symptoms, disease (diagnosis)
The date on which the subject or investigators first notice the signs 
or symptoms of an AE will be recorded.
Asymptomatic disease
The date on which a diagnostic test is conducted and the diagnosis 
is confirmed will be recorded.
The date on which diagnosis is confirmed will be recorded even 
when test findings belatedly reveal older findings or when the time 
of onset can be generally estimated.
Worsening of complications or PTEs
The date on which the subject or investigators first notice 
worsening of signs or symptoms will be recorded.
When initial test results after 
informed consent are normal but 
subsequent test results are abnormal 
(PTE)
When test results turn abnormal after 
start of study drug treatment (AEs)
The date on which laboratory abnormalities considered clinically 
significant are found will be recorded.
When test results after informed 
consent are initially normal but then 
worsen (PTE)
When test results at start of study 
drug treatment are abnormal and then 
worsen (AE)
The date of tests on which laboratory profiles reveal clear increases 
or decreases based on clinical judgment.
10.1.10 Date Resolved
The date resolved (the stop date of the AE/PTE) is the date on which AEs resolve 
(including resolved with sequelae). When AEs result in death, the date of death will be 
used. When an AE is recorded as a separate AE in the eCRF due to worsening of 
severity, the day before the date on which worsening was confirmed will be recorded as 
the date of resolution. Cases in which resolution cannot be confirmed at the end of the 
study will be assessed as ongoing.
10.1.11 Frequency
When an AE that apparently resolves and occurs repeatedly (such as constipation, 
diarrhea, and vomiting) is determined by investigators to be a series of occurrences 
constituting a single event over the period of time from initial onset to ultimate 
resolution, the incidence will be considered "intermittent." All other cases will be 
handled as "continuous."

10.1.12 Action Taken for Study Drug
Actions taken for study drug will be classified and defined as follows.
Drug Withdrawn
A study drug is terminated due to the particular AE (including when subjects 
themselves decide to discontinue).
Dose not Changed
The particular AE did not require any dose change of study drug.
Discontinuation of study drug, dose reduction, or dose escalation due to AE other 
than the AE in question will be handled as "dose not changed."
Discontinuation of study drug or dose reduction for reasons other than action taken 
for the AE, such as subject carelessness, will be handled as "dose not changed."
Unknown
When subjects cannot be contacted and the course after the date of onset cannot be 
ascertained, etc.
Not Applicable
When study drug treatment has already been completed or discontinued at the time 
that the AE occurs
Dose Reduced
A reduction in study drug dose as action taken for the AE will be handled as "dose 
reduced"(the dose cannot be reduced at the subject's discretion)
Dose Increased
An escalation in study drug dose as action taken for the AE will be handled as "dose 
increased"(the dose cannot be escalated at the subject's discretion)
Dose Interrupted
A temporary discontinuation (suspension) of study drug as action taken for the AE
followed by the resumption of dosing on a later date (including when subjects 
themselves decide to temporarily discontinue) will be handled as a "dose 
interrupted."
10.1.13 Outcome
The outcome of AEs will be classified as follows:
Classification
Criteria
Recovered/
Resolved
Symptoms or findings resolve or recover
Test results normalize or return to levels at baseline (AEs) or to levels at informed

Procedures
10.2.1
Collection and Reporting of Adverse Events
10.2.1.1
Collection Period of Pretreatment Events and Adverse Events
Pretreatment events will be recorded continuously from when informed consent is 
obtained until the first dose of study drug (Day 1). If it is decided that a subject should be 
withdrawn before the first dose of study drug, PTEs will be recorded until that point in 
time.
AEs will be recorded continuously from the start of study drug administration to subjects 
(Day 1) until the safety follow-up.
10.2.1.2
Reporting of Adverse Events
Investigators will check for subjective symptoms whenever subjects visit. Investigators 
will ask subjects about AEs that may have occurred since the last visit by asking 
questions such as "How have you been since the last visit?"
Any subjects who experience a PTE that meets the criteria for seriousness will be 
followed up by investigators until symptoms resolve or until medically significant 
laboratory abnormalities return to initial levels after informed consent, or else (in the case 
of a permanent or irreversible PTE) until the observed change can be satisfactorily 
explained. No protocol follow-up will be required for PTEs that do not meet the criteria 
for seriousness, regardless of the causal relationship to study procedure.
Any subjects who experience an AE will be followed up by investigators until symptoms 
resolve or until medically significant laboratory abnormalities return to initial levels after 
informed consent, or else (in the case of a permanent or irreversible AE) until the 
observed change can be satisfactorily explained, regardless of the causal relationship to 
study drug. All AEs will be recorded in the eCRF. The following information will be 
documented for each event: event term, start and stop dates, frequency, severity
(intensity), causal relationship to study drug (related, not related), action taken on study 
drug, outcome, causal relationship to study procedures (and procedure considered the 
cause if causally related), and seriousness.
AEs, and PTEs meeting the criteria for seriousness, will be followed up until the 
AE/PTEs resolve or until investigators determine that no further follow-up is needed.

10.2.1.3
Reporting of Special Interest Adverse Events
When an AE of special interest that occurs during the period for recording AEs is 
determined to be medically significant based on the following criteria, investigators will 
report the event to the sponsor (see attachment for contact information) within 24 hours 
of the onset of the AE of special interest or within 24 hours after learning of the event 
from the subject. The principal investigator will also prepare a report of LFT 
abnormalities (same report form as for SAEs) within 10 business days, and submit it with 
a signature or printed name and personal seal to the contact identified in the attachment. 
The "Liver Function Test Abnormality Reporting Checklist (Appendix I)" will be used as 
reference to assist in the preparation of the report.
The criteria for LFT abnormalities are given below:
• ALT or AST > 3 ULN
If ALT or AST levels are > 3 ULN and total bilirubin levels are > 2 ULN or the PT-
INR is > 1.5, and investigators conclude that the levels cannot be explained by any factor 
other that study drug based on the results of retesting (for procedures, see Section 
10.1.5.1), then they will be handled as serious AEs, and information will be recorded and 
reported by the procedures noted in Section 10.2.2.
AEs of special interest will be recorded as AEs in the eCRF. Related information (such as 
photographs, results of additional diagnostic tests, and records of consultations with 
specialists) will also be submitted to the sponsor.
10.2.2
Collection and Reporting of Serious Adverse Events
SAEs that occur in the period for recording AEs will be reported by the following 
procedures. PTEs meeting the criteria for seriousness noted in Section 10.1.4 will be 
reported by the same procedure as SAEs.
All SAEs that occur from the start of study drug administration in subjects until the safety 
follow-up will be reported by the principal investigator to the sponsor within 24 hours of 
confirming or being notified of the event. The initial report of an SAE and all revised or 
additional information will be recorded in an "SAE Report" to be submitted to the 
sponsor. Copies of related source documentation on medical treatment of subjects will be 
submitted to the sponsor as soon as possible. In cases of death, a copy of the autopsy 
report will be submitted, if possible.
Even after the end of the study, treatment-related SAEs will be reported to the sponsor 
within 24 hours of confirming or being notified of the event.
SAEs leading to withdrawal from the study or discontinuation of study drug will be 
recorded in initial or subsequent "SAE Reports" and in the eCRF.
As a general rule, the initial report of an SAE will be faxed to the Safety Information 
Emergency Response Center using the prescribed "Report of an SAE [Initial Report]" 
form. After faxing the form, the principal investigator will submit the original to the 
monitors.

information will be faxed to the Safety Information Emergency Response Center using 
the prescribed "Report of SAEs (Detailed Information)" form. After faxing the form, the 
principal investigator will submit the original to the monitors. Any modifications of the 
contents of the report will be similarly reported.

form.
All SAEs occurring onsite will be reported by the principal investigator to the head of the 
investigational site by the established procedures in force at the investigational site and to 
the sponsor in accordance with this protocol.
The expectedness of SAEs will be determined on the basis of the Investigator's Brochure 
(including information on AEs reported to investigational site).
10.2.3
Reporting of Drug-Induced LFT Abnormalities Potentially Leading to 
Severe Liver Disorders
Investigators will report ALT or AST levels > 3 ULN to the sponsor and will promptly 
investigate detailed subject information and potential causes other than study drug 
(presence or absence of acute viral hepatitis type A or B, or other acute liver diseases, 
medical history, and complications). Retesting will also be performed (see Section 
10.1.5). If ALT or AST levels are > 3 ULN and total bilirubin levels are > 2 ULN 
or the PT-INR is > 1.5, and investigators conclude that the levels cannot be explained by 
any factor other that study drug, the information will be reported by the same procedure 
for SAEs (see Section 10.2.1.3).
10.3
Follow-up of Serious Adverse Events
If information not reported in the detailed report becomes available at a later date, 
investigators will record the information on a copy of the SAE report or will prepare a 
separate document, and one or the other will be submitted to the contact identified in the 
attachment. Investigational site-related data (such as ECG findings, laboratory findings, 
summary of report of discharge from hospital, and results of autopsy) will be submitted 
upon request to the sponsor or the IRB.
Investigators will follow-up all SAEs until they resolve or until the final outcome is 
determined.

authorities, principal investigators, and the IRBs/head of the investigational site in 
accordance with the local regulations of the counties in which the study is being 
conducted. The sponsor or the sponsor's CRO will submit an expedited report of fatal or 
life-threatening SUSARs within 7 days, and of any other serious events within 15 days, 
of first learning of or obtaining additional information on the event to the regulatory 
authorities. The sponsor will also submit an expedited report of other safety issues
potentially having a significant effect on the benefit-risk assessment of study drug, 
continuation of study drug treatment, or continuation of the study. The investigational 
site also will forward a copy of all expedited reports to his or her IRB.

be coded using the Medical Dictionary for Regulatory Activities (MedDRA). Drugs will 
be coded using the World Health Organization (WHO) Drug Dictionary [generic term] 
and the Japanese Drug Dictionary.
12.1
Electronic Case Report Form
Completed eCRFs are required for each subject who signs informed consent.
The sponsor or its designee will supply the investigational site with access to the eCRF 
system. The sponsor will make arrangements to train the investigators and appropriate 
study support staff in use of the eCRF system. The eCRFs will be used to transmit the 
information collected during the study to the sponsor and regulatory authorities. The 
eCRF must be completed in English. Data will be directly recorded onto eCRF.
The following will be recorded as an audit trail when changes or revisions are made in 
the eCRF: the original and changed/revised information, person making the change or 
revision, and the date and reasons for the change or revision.
The principal investigator must review the eCRFs for completeness and accuracy, and 
must electronically sign the appropriate page of the eCRF. The principal investigator 
bears full responsibility for the accuracy and reliability of all data recorded in the eCRFs.
The following data will not be directly recorded in the eCRF.
1)
Tumor marker, BMP concentration, and pharmacodynamic parameters (except for 
SHBG) measured by an external measurement facilities.
2)
Plasma drug concentration results
Investigators will use the eCRF change and revision record (Data Clarification Form) 
provided by the sponsor when changing or revising recorded entries in the eCRF after the 
clinical trial database has been locked. The principal investigator must review the data 
change for accuracy and completeness, and must provide a signature or printed name and 
personal seal, and the date.
The sponsor or its designee will check the accuracy and completeness of the eCRF when 
visiting the investigational site. The sponsor or its designee will be permitted to review 
subject's medical and hospital records related to the study to ensure the accuracy of the 
eCRFs. Completed eCRFs are the property of the sponsor, and should not be made 
available in any form to third parties other than regulatory authorities without the written 
permission of the sponsor.
12.2
Record Retention
The principal investigator or head of the investigational site will keep the following 
records, including the records and study-specific documents specified in Section 12.1.  
These materials will include the identification log of all participating subjects, medical 
records, source worksheets, all original signed and dated informed consent forms,

13.1
Statistical and Analytical Plans
Analysts will prepare and finalize the Statistical Analysis Plan before database lock. The 
Statistical Analysis Plan will describe in detail the definitions of the endpoints and 
analytical methods in order to meet all study objectives.
Data review will take place before database lock. The accuracy and completeness of the 
study data, the evaluability of subjects, and the appropriateness of the planned analysis 
will be assessed during data review.
13.1.1
Analysis Sets
Four populations for analysis will be established in this study: the full analysis set, the 
safety analysis set, the DLT analysis set, and the pharmacokinetic analysis set. The 
safety analysis set will be defined as all subjects who receive at least 1 dose of any study 
drug. The DLT analysis set will be defined as all subjects who can be evaluated for 
DLTs (see Section 6.1.2.3). The analysis sets will be defined in detail in the separately 
prepared "Rules for Handling Analytical Data."
Before database lock, the sponsor will consult the medical expert as needed to check on 
the appropriateness of the analysis set definitions and rules for handling the analysis of 
the case data in the sets, and will finalize the "The Rules for Handling Analytical Data" 
after deciding how to handle problematic issues not specified at the planning stage.
13.1.2
Analysis of Demographics and Other Baseline Characteristics
The primary subject characteristics in the safety analysis set will be tabulated. 
Descriptive statistics (number of subjects, mean, median, standard deviation, maximum,

QUALITY CONTROL AND QUALITY ASSURANCE
14.1
Monitoring of Investigational Site
Monitoring visits to the investigational site will be made periodically during the study to 
ensure that all aspects of the protocol are followed. Source documents will be reviewed 
for verification of data recorded on the eCRFs. Source documents are defined as original 
documents, data, and records. The investigator and institution guarantee access to source 
documents by the sponsor or its designee and by the IRB.
The sponsor or its designee will access the principal investigator's files, medication, 
medical records of subjects, and records such as the informed consent form to ensure that 
the study is being properly conducted in compliance with the protocol. They will also 
confirm the consistency of the eCRFs with related source documents. Investigators and 
other study support staff members will take the time to accommodate monitors when they 
visit the investigational site for monitoring purposes.
14.2
Protocol Deviations
Investigators may deviate from or modify the protocol without the prior written 
agreement of the sponsor or prior approval of the IRB for medically unavoidable 
circumstances, such as to avoid immediate hazards to subjects. On such occasions, the 
principal investigator will inform the sponsor and head of the investigational site in 
writing of the details of and reasons for the deviation or change, will keep copies of the 
notification, and will reach agreement with the sponsor on protocol revisions as needed.  
If the protocol is to be revised, a draft will be submitted as soon as possible to the head of 
the investigational site, and the approval of the IRB will be required.
Investigators should document all deviations from the protocol.
14.3
Quality Assurance Audits and Regulatory Authority Inspections
The sponsor or designee will audit the investigational site as needed. On such occasions, 
an auditor designated by the sponsor will contact the investigational site beforehand to 
schedule the auditing visit. The auditor may ask to visit the facilities where laboratory 
test samples are kept, the facilities where medication is stored and prepared, and other 
facilities used during the study. During this study, inspections may also be carried out by 
regulatory authorities, including overseas agencies (such as the US Food and Drug 
Administration [FDA] and the UK Medicines and Healthcare Products Regulatory 
Agency [MHRA]).  The sponsor will be notified immediately whenever the 
investigational site receives a request for an inspection by the regulatory authorities.  The 
principal investigator and head of the investigational site will ensure that the auditor has 
access to all study-related documentation set forth in Section 14.1.

ETHICAL ASPECTS OF THE STUDY
This trial will be conducted with the highest respect for the individual participants (ie, 
subjects) according to the protocol, the ethical principles that have their origin in the 
Declaration of Helsinki, and International Conference on Harmonisation (ICH) 
Guidelines for GCP. Investigators will conduct the study in accordance with regional 
regulatory requirements and the "Responsibilities of the Principal Investigator" in
Appendix F.
15.1
IRB Approval
The IRB must be will be constituted according to the applicable local regulations in 
regions participating in the study. The sponsor or designee will obtain documentation of 
the names and affiliations of the IRB members. When IRB members directly participate 
in the study, documentation that they are not involved in the review and decision-making 
process must be obtained.
The sponsor or designee will submit related documents to the IRB for review and 
approval of the protocol. In addition to the study protocol, Investigator's Brochure and 
copies of the informed consent as well as materials and advertising related to the 
recruitment of subjects, if needed, and other documents required by local regulations 
must also be submitted to central or local IRBs for approval. The sponsor or designee 
will obtain documented approval of the protocol and informed consent form by the IRB 
before the start of the study (ie., before shipment of the sponsor-supplied drug or study 
specific screening activity). The IRB or IEC approval must refer to the study by exact 
protocol title, number, and version date; identify versions of other documents (eg, 
informed consent form) reviewed; and state the approval date. The sponsor will ship drug
after confirming the appropriateness of the documented regulations of the investigational 
site. Until the site receives drug, no protocol activities, including screening may occur.
The investigational site will follow all requirements specified by the IRB. This includes 
notifications to the IRB regarding protocol amendments, updates to the informed consent 
form, revisions of materials related to subject recruitment, reports on safety required by 
local regulatory requirements, periodic reports on the conduct of the study as stipulated 
by the IRB, and the study completion report. The sponsor or designee will obtain all 
documented IRB approval of the above and related materials.
Financial compensation paid to subjects should be kept to a level that will not provide 
undue incentive to participate in the study. Financial relief must be approved by the IRB 
and sponsor.
PGx analysis of collected and stored samples will perform at the time when the details 
have been decided. At that time, the sponsor will prepare a PGx protocol, and the
protocol will require prior approval of the sponsor.
15.2
Patient Information, Informed Consent, and Subject Authorization
Written consent documents will embody the elements of informed consent as described in 
the Declaration of Helsinki and the ICH Guidelines for GCP and will be in accordance 
with all applicable laws and regulations. The informed consent form will describe the 


TAK-385 
TB-AK160108
Page 87 of 112
Amendment 2
1 July 2015
CONFIDENTIAL
planned and permitted use (either in Japan or abroad: submission to third parties) and 
disclosure of the personal information and personal medical information of subjects in 
this study. The informed consent form will further explain the nature of the study, 
objectives, and of the potential risks and benefits. The informed consent form will also 
detail the requirements of the participant and the fact that he or she is free to withdraw at 
any time without giving a reason and without prejudice to his or her further medical care.
The principal investigator is responsible for the preparation and contents of the informed 
consent form, and for obtaining the approval of the IRB. The informed consent form 
must be approved by the IRB before being used.
The informed consent form must be written in a language fully comprehensible to the 
prospective subject. Investigators will be responsible for providing subjects with a 
detailed explanation of the contents of the informed consent form. Information should be 
provided verbally and in writing by a method deemed suitable by the IRB whenever 
possible.
Investigators will give subjects (1) a chance to ask questions about the study and 
(2) enough time to decide whether to participate in the study. Subjects who decide to 
participate in the study will personally sign and date the informed consent form before 
participating in the study. Investigators will ask subjects to use a black or blue ball point 
pen to sign the form using their full legal names. Investigators will also sign and date the 
informed consent form before the subject can participate in the study.
Investigators will keep the signed original informed consent form. The date on which 
subjects sign the informed consent form will be recorded by investigators in the medical 
records of the subjects. Subjects will be given a copy of the signed informed consent 
form.
If the informed consent form is revised, investigators will again obtain the informed 
consent of the subjects using the same procedures that were used to obtain initial consent. 
The date on which informed consent is again obtained will be recorded in the medical 
records of the subjects, and subjects will be given a copy of the revised informed consent 
form.
Subjects who have received an explanation of the study based on the informed consent 
form will be given an explanation of PGx analysis based on the "Informed Consent Form 
for PGx Analysis in the TAK-385 Study." Specimens for PGx analysis will be obtained 
from subjects who sign both the informed consent for the study and the informed consent 
for PGx analysis.
The procedure in Section 9.4 will be followed whenever subjects would prefer their 
stored samples to be disposed of.
15.3
Subject Confidentiality
The sponsor or designee affirm and uphold the principle of the subject’s right to 
protection against invasion of privacy. Throughout this study, a subject’s source data 
will only be linked to the sponsor’s clinical study database or documentation via a unique 
subject identification number. As permitted by all applicable laws and regulations, 


TAK-385 
TB-AK160108
Page 88 of 112
Amendment 2
1 July 2015
CONFIDENTIAL
limited subject attributes, such as sex, age, or date of birth, and subject initials may be 
used to verify the subject and accuracy of the subject identification number.
To comply with ICH Guidelines for GCP and to verify compliance with this protocol, the 
sponsor requires the investigator to permit its monitor or designee’s monitor, 
representatives from any regulatory authority (such as the FDA, MHRA, and PMDA), the 
sponsor’s designated auditors, and the appropriate IRBs and IECs to review the subject’s 
original medical records (source data or documents), including, but not limited to, 
laboratory test result reports, ECG reports, admission and discharge summaries for 
hospital admissions occurring during a subject’s study participation, and autopsy reports. 
Access to a subject’s original medical records requires the specific authorization of the 
subject as part of the informed consent process (see Section 15.2).
Copies of any subject source documents that are provided to the sponsor must have 
certain personally identifiable information removed (ie., the subject's name, address, and 
other identifier fields not collected on the subject's eCRF).
15.4
Publication, Disclosure, and Clinical Trial Registration Policy
15.4.1
Publication and Disclosure
The principal investigator is obliged to provide the sponsor with complete test results and 
all data derived by the investigator from the study. During the study, except when 
required by laws or regulations, only the sponsor may disclose study information to other 
investigators or regulatory authorities. Except where otherwise permitted by the Clinical 
Study Agreement, any public disclosure of the protocol and study results (including 
public websites) is the responsibility of the sponsor.
The sponsor may publish any data or information obtained from the study (including data 
and information provided by the principal investigator) without the consent of the 
principal investigator.
Investigators need to obtain the prior written permission of the sponsor to publish any 
information obtained from the study, such as to a professional associations.
15.4.2
Clinical Trial Registration
In order to ensure that information on clinical trials reaches the public in a timely manner 
and to comply with applicable laws, regulations and guidance, Takeda will, at a minimum 
register interventional clinical trials it sponsors anywhere in the world on a public 
website (JAPIC-CTI) before the start of the clinical trial. The sponsor's contact 
information will be registered for general access along with the city, state (in the USA), 
and country where the trial is being conducted as well as subject recruitment status.
For some registries, Takeda will assist callers in locating trial sites closest to their homes 
by providing the investigator name, address, and phone number to the callers requesting 
trial information. Once subjects receive investigator contact information, they may call 
the site requesting enrollment into the trial. The investigative sites are encouraged to 
handle the trial inquiries according to their established subject screening process. If the 


TAK-385 
TB-AK160108
Page 89 of 112
Amendment 2
1 July 2015
CONFIDENTIAL
caller asks additional questions beyond the topic of trial enrollment, they should be 
referred to the sponsor.
Any investigator who objects to Takeda providing this information to callers must 
provide Takeda with a written notice requesting that their information not be listed on the 
registry site.
15.4.3
Clinical Trial Results Disclosure
Takeda will post the results of clinical trials on a public website (JAPIC-CTI), as required 
by applicable laws and/or regulations, regardless of the results.
15.5
Insurance and Compensation for Injury
Each subject in the study must be insured in accordance with the regulations applicable to 
the site where the subject is participating. If a local underwriter is required, then the 
sponsor or its designee will obtain clinical study insurance against the risk of injury to 
clinical study subjects.
Refer to the Clinical Study Agreement regarding the sponsor’s policy on subject 
compensation and treatment for injury. If the investigator has questions regarding this 
policy, he or she should contact the sponsor or its designee.

efficacy over a longer period, in light of the fact that the safety and efficacy of TAK-385 
in multiple dosing for 28 days will have been confirmed in Part A. If the investigator
determines after 48 weeks that there are no safety problems and that TAK-385 treatment 
may be continued, then treatment may be continued for up to a total of 96 weeks.

Revised Text
(3) Rationale for dosage in Part A, Cohort 4
19.320 mg or 360 mg may be selected as the loading dose in the planned phase 3 
multinational study. Based on this situation, a new cohort, Cohort 4, was added 
to Part A in Amendment 2 of the study protocol, designed to evaluate the 
tolerability of loading dose of 360 mg in Japanese patients before joining the 
phase 3 multinational study.  As for the maintenance dose, the same dose as 
Part A, Cohort 2 (120 mg) was selected, since this dose is expected to keep 
serum testosterone at castration levels and maintain this effect.

Amendment 2
XX XXXX, 2015
CONFIDENTIAL
20.As described in the section above, the tolerability of single doses of 360 mg and 
multiple doses as high as 160 mg (for 28 days) has been confirmed in a phase 1 
study in healthy adult males that was conducted in Europe (TAK-385_C27001).
 
  Based on the fact that there are no major 
differences between Japanese and Americans in the pharmacokinetic or 
pharmacodynamic profiles of TAK-385, and that there are no major differences 
between the pharmacokinetic profiles obtained in healthy adult men and 
women, there are no safety concerns in using the loading dose of 360 mg and 
maintenance dose of 120 mg in Part A, Cohort 4.

STUDY SUMMARY
Name of Sponsor:
Takeda Pharmaceutical Company Limited
Study Drug:
TAK-385
Study Title: A Phase 1, Open-label, Multicenter Study 
to Evaluate the Tolerability, Safety, Pharmacokinetics, 
and Pharmacodynamics of TAK-385 Alone in Hormone 
Treatment-naive Japanese Patients With Non-metastatic 
Prostate Cancer
IND Number:
NA
EudraCT Number:
NA
Study Number: TB-AK160108
Phase: 1
Study Design:
This study consists of two parts: Part A, a dose-rising phase, and Part B, an expansion phase.
In Part A, three to six patients will be enrolled in each cohort. Whether or not the study will proceed to the
next cohort or Part B will be determined through assessment of tolerability at the dose in question, based on 
the incidence of dose-limiting toxicity (DLT) in the evaluation period. TAK-385 will be taken once a day 
for 28 days at the doses assigned to each cohort. Cohort 1 will receive a loading dose of 320 mg and a 
maintenance dose of 80 mg, Cohort 2 will receive a loading dose of 320 mg and a maintenance dose of 
120 mg, and Cohort 3 will receive a loading dose of 320 mg and a maintenance dose of 160 mg. Patients 
being switched to a gonadotropin-releasing hormone (GnRH) agonist (eg, leuprorelin) or a GnRH 
antagonist (eg, degarelix) following the completion of TAK-385 treatment in Part A will first pass through 
a 1-week observation period (except for study withdrawals). Whether or not the study will proceed to Part 
B will be determined by the study sponsor after consulting the study monitoring committee (SMC) based 
on a comprehensive evaluation of the tolerability and safety data from Cohort 2 of Part A.
In Part B, subjects will be randomized to receive study drug (TAK-385 loading dose of 320 mg and 
maintenance dose of either 80 mg or 120 mg – equal numbers of subjects will be randomized to 80 mg and 
120 mg) once a day orally to evaluate safety. In addition to the safety assessments, efficacy assessments 
will also be performed according to the study schedule, and study drug will be administered until the 
discontinuation criteria (Section 7.5) are met for each individual subject. After completing 48 weeks of 
treatment, subject may, at the discretion of the investigator, and depending on the wishes of the subject, 
continue receiving study drug (for a maximum of 96 weeks), or they may complete the study and be 
switched to a GnRH agonist or a GnHR antagonist, starting from the day after the day of the last dose of 
TAK-385.
All subjects who receive study drug will undergo safety follow-up 30 to 40 days after the last dose of 
TAK-385.
Part A (Dose-rising phase)
Primary Objectives:
To evaluate the tolerability and safety of TAK-385 in hormone treatment-naive patients with non-
metastatic prostate cancer.
Secondary Objectives:
To evaluate the pharmacokinetics (PK) and the effects on serum testosterone of TAK-385 in hormone 
treatment-naive patients with non-metastatic prostate cancer.
Part B (Expansion phase)
Primary Objectives:
To evaluate the safety of TAK-385 in hormone treatment-naive patients with non-metastatic prostate 
cancer.
Secondary Objectives:
To evaluate the change over time in the prostate-specific antigen (PSA) levels and the PK and effects on 
serum testosterone of TAK-385 in hormone treatment-naive patients with non-metastatic prostate cancer.

INTRODUCTION
4.1
Summary
In 2008 prostate cancer reached approximately 900,000 cases/year worldwide and is now 
the second leading cancer in men, accounting for 13.7% of cancer cases in men [1]. The 
median age of diagnosis is 70, and prostate cancer is rarely diagnosed in men under 40 
[2]. Incidence increases with age and is expected to rise in the future as the population 
ages. In Japan, 2008 statistics show that prostate cancer ranks a high fourth in morbidity 
among cancers in men [3]. Prostate cancer in Japan also occurs more often with age, and 
the incidences increases rapidly in men 60 and older.
It is known that prostate cancer is to responsive to surgical castration and that the 
effectiveness of this therapy results from the elimination of androgen. This knowledge 
led to the understanding that most prostate cancers are growth hormone dependent and 
ever since this discovery, hormone therapy has played an important role in the treatment 
of prostate cancer.
Castration by orchiectomy or a gonadotropin-releasing hormone (GnRH) agonist is the 
main mode of therapy for localized progressive and metastatic cancers, and GnRH 
agonists such as leuprorelin acetate are widely used [4]. When multiple doses of a GnRH 
agonist are administered, a temporary increase in gonadotropin secretion (flare up) occurs. 
That is followed by a decrease in responsiveness (desensitization) in the pituitary gland 
and gonads, which appears to work effectively by inhibiting the secretion of sex 
hormones. The flare up sometimes leads to a temporary worsening of symptoms, and the 
effectiveness of GnRH agonist begins to appear about 3 to 4 weeks after the initial dose.  
In addition, the GnRH is a peptide formulation and is unable to be administered orally. 
Consequently, development of a new medication that is easy to administer and does not 
cause flare ups is needed.
TAK-385 is a non-peptide orally active GnRH antagonist with a novel structure that was 
discovered by Takeda Pharmaceutical Company, Ltd. TAK-385 antagonizes GnRH at the 
GnRH receptors present in the basophils (secreting cells) of the anterior pituitary gland 
and inhibits the GnRH-stimulated secretion of gonadotropin luteinizing hormone (LH) 
and follicle-stimulating hormone (FSH) from those cells. This action lowers the serum 
testosterone concentration in the blood. An antitumor effect is expected in prostate 
cancer patients due to the suppression of serum testosterone production by the testes. 
TAK-385 is also expected to manifest its effects rapidly without causing flare ups like 
GnRH agonists. Moreover, because it is a non-peptide formulation, TAK-385 can be 
administered orally, unlike peptide-based GnRH agonists that must be absorbed 
subcutaneously. The clinical pharmacokinetic and pharmacodynamic profiles may offer 
additional advantages compared with a depot peptide formulations, such as more rapid 
recovery from short term medical castration.
Takeda Pharmaceutical Co., Ltd. decided to develop TAK-385 for the treatment of 
prostate cancer both overseas and in Japan. Moreover, development of TAK-385 in Japan 
and Asia for endometriosis and uterine fibroids is already underway.

4.1.2.5
Overseas Phase 1 Single- and Multiple-dose Study (TAK-385_C27001)
Study C27001 was a phase 1 study that evaluated the safety, tolerability, PK, and PD of 
TAK-385 in 176 healthy English adult male subjects (128 subjects received TAK-385) 
receiving single doses of TAK-385 up to 360 mg QD and multiple doses of TAK-385 up 
to 180 mg QD for up to 28 days. The study had 4 parts: Part 1 included single-dose 
administration of TAK-385 to 32 subjects across 4 dose cohorts plus placebo and had a 
fed/fasted arm; Part 2 included multiple dose administration of TAK-385 for 14 days to 
40 subjects across 5 dose cohorts plus placebo; and Parts 3 and 4 included multiple dose 
administration of TAK-385 for 28 days to 66 and 38 subjects, respectively, across 2 dose 
cohorts (a total of 4 dose levels), plus placebo.
There were no deaths or SAEs following single-dose or multiple-dose treatment with 
TAK-385 for 14 or 28 days.
Following 28 days of QD dosing, there were 3 discontinuations due to drug-related, 
hepatic AEs: 2 subjects in the 160 mg dose cohort in Part 3 of the study discontinued 
treatment due to Grade 1 AEs of hepatic enzyme increased (ALT and AST); and 1 subject 
in the 60 mg dose cohort in Part 4 of the study discontinued treatment due to a Grade 2 
AE of liver function test (LFT) abnormal (ALT and AST). There was no clear trend 
between dose level and toxicity, although abnormal liver transaminase levels appeared 
more likely to occur within 2 weeks at higher dose levels. All AEs resolved by the end of 
the study.
The majority of subjects had at least 1 AE, but no increase in the incidence of AEs with 
increasing dose of TAK-385 was observed. The most common AEs observed across all 
dose cohorts were bradycardia, hot flush, and headache, and the most common, drug-
related AE was hot flush.
A number of cardiac AEs according to Common Terminology Criteria for Adverse Events 
(CTCAE) were reported, but for these subjects the ECG interpretation was considered to 
be not clinically significant by the investigator. These cardiac AEs included 
electrocardiogram QT prolonged (1 AE in Part 1, 4 AEs in Part 2, and 7 AEs in Part 3) 
and first degree atrioventricular block (2 AEs in Part 1 and 6 AEs in Part 2). Changes in 
mean QTc interval of approximately 15 to 20 msec were noted before administration on 
Day 14 (80 to 180 mg QD) in adult male subjects in this study. The QTc changes were 
independent of drug administration, not correlated to drug levels, and are similar to those 
observed in surgical and medical castration studies with other compounds. No major 


TAK-385

safety concerns were noted in healthy male subjects receiving single (80 to 360 mg) and 
multiple (20 to 180 mg) doses of TAK-385, and TAK-385 was well tolerated.
Single doses of 80 to 360 mg of TAK-385 administered orally (fasted state) were 
absorbed rapidly in plasma with median Tmax values ranging from 1.75 to 4.00 hours 
after administration across the entire dose range. After attaining Cmax, TAK-385 plasma 
concentrations declined in a multi-exponential manner with a mean T1/2 ranging from 
19.1 to 21.7 hours. The mean Cmax and AUC values for TAK-385 generally increased in 
an approximately dose-proportional manner over the 80 to 360 mg dose range.
When a multiple dose of 20 to 180 mg QD of TAK-385 was administered, the drug was 
readily absorbed in plasma on Days 1 and 14, and Cmax typically occurred within 1 to 2 
hours after dosing. After attaining Cmax, individual PK profiles on Day 14 exhibited a 
multi-exponential elimination phase with a mean elimination phase T1/2 of 
approximately 36 to 65 hours at doses of 20 to 180 mg QD. The trough concentration-
time data (Day 2, and Days 11 to 14) implied that steady-state conditions were attained 
within approximately 10 days.
Similarly, the effect of food was studied in 6 male subjects in the crossover period (Part 
1). Compared to fasting conditions, the absorption of TAK-385 in plasma decreased and 
was delayed following a single 180 mg dose taken 30 minutes after the start of a standard 
FDA high-fat, high-calorie breakfast. Least square mean Cmax and AUC(0-inf) values 
decreased by approximately 52% and 47%, respectively. Furthermore, median Tmax 
increased from 1.75 hours to 5.00 hours under fed conditions. When the dose was 
administered 30 minutes prior to the standardized morning meal (Part 2), systemic 
exposure to TAK-385 appeared to be reduced to a lesser extent (approximately 28% on 
average) and no changes in the absorption rate were observed.
In this study, serum LH, FSH, dihydrotestosterone (DHT), and testosterone 
concentrations were determined following single and multiple oral doses of TAK-385 or 
placebo for up to 28 days. TAK-385 caused an immediate and effective suppression of 
gonadotropins (LH, FSH) and testosterone. While no changes were observed in the 
placebo group, serum testosterone levels were markedly suppressed in all TAK-385 dose 
groups within the first 3 days of administration. Loading doses of 320/240/160 mg for up 
to 3 days and doses of 180 mg or greater led to testosterone levels below the conventional 
castration level within 48 hours. The onset of the testosterone lowering response 
shortened as the loading dose increased. This phenemon was likely a result of higher 
TAK-385concentrations in the blood. Similar dose-dependent suppressive effects were 
observed after a single oral dose. These findings support the principal mechanism of 
action that, as a GnRH antagonist, TAK-385 competitively binds with the pituitary GnRH 
receptors.
In administration over 28 days in Part 3 and 4, both 160 mg and 80 mg QD were effective 
at achieving conventional medical castration levels during the third and fourth weeks of 
multiple administration. Despite the loading dose regimen, however, the 40-mg QD dose 
was ineffective in maintaining castration levels between Days 14 and 28. The results at 
60 mg QD were intermediate to those of 40 and 80 mg QD and suggested that the likely 


TAK-385

minimal, fully effective maintenance dose for medical castration would be 80 mg QD or 
above [5].
4.2
Rationale for the Proposed Study
The results of the phase 1 study conducted in England (TAK-385_C27001) demonstrate 
the tolerability of multiple doses of TAK-385 (20 to 80 mg) in healthy adult men. 
Moreover, the plasma concentration of TAK-385 increased as the dose increased, and 
rose slightly greater than dose proportionality. The blood concentrations of the measured 
hormones all decreased rapidly with multiple doses of TAK-385 and effective 
suppression of serum testosterone was sustained throughout the adminsitration period.
 
Because prostate cancer is a sex-hormone dependent disease, and an antitumor effect is 
expected as a result of lowering hormone concentrations in the blood through 
administration of TAK-385, it was decided to conduct a phase 1 study in patients with
prostate cancer.
This protocol was prepared in accordance with the Good Clinical Practice (GCP).

STUDY DESIGN AND DESCRIPTION
6.1
Study Design
This is a multicenter phase 1, open-label, dose range-finding study to evaluate the 
tolerability, safety, PK, and pharmacodynamics of TAK-385 alone in hormone treatment-
naive Japanese patients with non-metastatic prostate cancer.
This study consists of two parts: Part A, a dose-rising phase, and Part B, an expansion 
phase. The designs of Part A and Part B are shown in “Study Design and Treatment 
Schema” (Figure 6.a and Figure 6.b).
In Part A, three to six patients will be enrolled in each cohort. Whether or not the study 
will proceed to the next cohort or Part B will be determined through assessment of 
tolerability at the dose in question, based on the incidence of DLT in the evaluation
period (treatment initiation to Day 28).
TAK-385 will be taken once a day for 28 days at the doses assigned to each cohort. 
Cohort 1 will receive a loading dose of 320 mg and a maintenance dose of 80 mg, Cohort 
2 will receive a loading dose of 320 mg and a maintenance dose of 120 mg, and Cohort 3 
will receive a loading dose of 320 mg and a maintenance dose of 160 mg. The doses will 
be taken orally at least 30 minutes before breakfast. Patients being switched to a GnRH 
agonist (eg, leuprorelin) or a GnRH antagonist (eg, degarelix) following the completion 
of TAK-385 treatment in Part A will first pass through a 1-week observation (no-
treatment) period. However, patients whose treatments were discontinued because they 
met the discontinuation criteria (Section 7.5) during the 28-day treatment period will not 
have to pass through this observation period.
If tolerability is confirmed in Cohort 2, then the study will proceed to Cohort 3 and Part B 
simultaneously. The tolerability in Japanese of the maximum dose at which tolerability 
was found in 28-day multiple dosing in the overseas phase 1 single-/multiple-dose study 
(TAK-385_C27001) (160 mg) will be evaluated for the purpose of checking the 
tolerability of dose escalation to 160 mg in Part B as well as the PK. In the overseas 
phase 1 single-/multiple-dose study (TAK-385_C27001), no findings indicative of safety 
problems were obtained in multiple dosing for 28 days with 160 mg. However, if 
tolerability is not confirmed in Cohort 2, then a cohort will be added that will receive a 
loading dose of TAK-385 320 mg and a maintenance dose of 40 mg.
In Part B, subjects will be randomized to receive study drug (TAK-385 loading dose of 
320 mg and maintenance dose of either 80 mg or 120 mg – equal numbers of subjects 
will be randomized to 80 mg and 120 mg) once a day orally to evaluate safety. In 
addition to the safety assessments, efficacy assessments will also be performed according 
to the study schedule, and study drug will be administered until the discontinuation 
criteria (Section 7.5) are met for each individual subject. After completing 48 weeks of 
treatment, subjects may, at the discretion of the investigator, and depending on the wished 
of the subhect, continue receiving study drug (for a maximum of 96 weeks), or they may 
complete the study and be switched to a GnRH agonist (eg, leuprorelin) or a GnHR 
antagonist (eg, degarelix), starting from the day after the day of the last dose of TAK-385.
Subjects withdrawing from the study will not be replaced.

If no problems with tolerability are found in the additional cohort in Part A, then the 
study will proceed to Part B with a 40 mg group instead of a 120 mg group (TAK-385 
loading dose of 320 mg and maintenance dose of 40 mg).
All subjects who receive study drug, whether in Part A or Part B, will undergo safety 
follow-up 30 to 40 days after the last dose of TAK-385.
*1: If tolerability is not confirmed in Cohort 2, then a cohort will be added which will receive a loading 
dose of 320 mg and a maintenance dose of 40 mg.
*2: If a cohort is added, and the additional cohort continues to the end and no problems with tolerability 
are found, then the study will proceed to Part B.

6.1.1
Cohort/Part Advancement Criteria
Whether or not the study will proceed to the next cohort in Part A will be determined by 
the study sponsor after consulting the study monitoring committee (SMC) and following 
a comprehensive evaluation of the safety data based on the number of subjects 
experiencing DLT in each cohort (Table 6.c). Drug will be administered to the subjects in 
the next cohort after the decision on cohort advancement is made. See the separately 
prepared written procedures for detailed study advancement criteria.
In each cohort, if no DLT occurs in even 1 of the 3 subjects during the DLT evaluation 
period (see Section 6.1.2.2), then the dose will be judged tolerable, and the study will 
proceed to the next cohort. If a DLT occurs in 1 subject in the DLT evaluation period, 
and additional 3 subjects will be enrolled in this cohort, and DLT will be evaluated in a 
total of 6 subjects. If DLT occurs in 1 of these 6 subjects, this dose will be judged 
tolerable, and the study will proceed to the next cohort. If DLT occurs in 2 or more 
subjects, the study will be stopped, but if it is determined, after consulting the SMC, that 
this dose is tolerable, then the study will proceed to the next cohort.
Whether or not the study will proceed to Cohort 3 and Part B will be determined by the 
study sponsor after consulting the SMC based on a comprehensive evaluation of the 
tolerability and safety data from Cohort 2 of Part A.
If the study cannot proceed from Cohort 2 to Cohort 3 and Part B because of a tolerability 
problem, the study will proceed to an additional cohort that will receive a TAK-385 
loading dose of 320 mg and a maintenance dose of 40 mg. In this case, as well, 3 
subjects will be enrolled, and assessed in the same manner as described above. If the 
study proceeds to the additional cohort, and continues until the treatment of the additional 
cohort has been completed, and it is confirmed that no problems with tolerability are 
found, then the study will proceed to Part B.
If DLT occurs in 2 or more subjects in Cohort 3, then whether or not to increase the dose 
to 160 mg in Part B will be determined in consultation with the SMC.

Because assessment of the MTD is not the objective of this study, additional subjects will 
not be enrolled if TAK-385 is found to be tolerable in an evaluation of the 3 subjects in 
Cohort 3, nor will additional subjects be enrolled at lower dose levels if TAK-385 is not 
found to be tolerable at the dose level initially investigated.

consecutive time points 7 or more days apart, except for ALT or AST > 3 upper 
limit of normal(ULN), total bilirubin > 2 ULN, or prothrombin time-international 
normalized ratio (PT-INR) > 1.5 at 2 time points 2 or more days apart.
2.
Either of the following ECG findings at 2 time points 7 or more days apart
QT/Fridericia corrected QT (QTcF) > 500 msec after treatment initiation
QT/QTcF interval prolongation > 60 msec postdose
The QTcF interval will be calculated using Fridericia’s equation (QT/RR0.33).
If it is difficult to determine whether or not an event is a DLT and the subject who 
experienced the event should be included in the DLT analysis set, the sponsor will consult 
the SMC before making a final decision on whether or not the event is a DLT.
Study treatment will be continued until the end of the 28-day treatment period unless a 
DLT occurs. If a subject is withdrawn from the study for a reason other than a DLT or if 
treatment compliance is below 80% (23 doses), the subject will be considered ineligible 
for inclusion in the DLT analysis set, and replacement subjects will be added in order to 
obtain 3 or 6 evaluable subjects.
6.1.2.2
DLT Evaluation Period
From treatment initiation until Day 28 in Part A.
6.1.2.3
DLT Evaluable Subjects
Subjects meeting any of the following criteria enrolled in a cohort in Part A.

Subjects who have taken at least 80% of the doses of TAK-385 (23 doses) during the 
DLT evaluation period and for whom the DLT evaluation period observations have 
been completed.

Subjects who experienced DLTs during the DLT evaluation period.
6.2
Rationale for Study Design, Dosage, and Endpoints
(1) Rationale for the target patient population and the study design
The novel GnRH antagonist TAK-385 is expected to compensate for the deficiencies 
of the GnRH agonists that have been widely used in the treatment of prostate cancer 
to date, and is being developed as a novel therapeutic medication for prostate cancer. 
The target patient population for this study was therefore made Japanese patients 
with prostate cancer.
Because this study will be the first time in Japan that TAK-385 will be administered 
to patients with prostate cancer, and the safety and efficacy of TAK-385 for the target 
population have not been sufficiently demonstrated, the TAK-385 treatment period in
Part A was set at 28 days. The treatment period would minimize the inconvenience 


TAK-385 
TB-AK160108
Page 34 of 119
Amendment 1
23 January 2015
CONFIDENTIAL
to subjects with safety concerns or insufficient efficacy. Because TAK-385 will be 
administered alone to hormone treatment-naive patients with prostate cancer, a 
placebo would not be used, and that the study would be conducted as an open-label 
study. It was also decided that if a subject is going to be switched to some other 
therapy after receiving the last dose of TAK-385 in Part A, then the patient would 
have to first pass through a 1-week observation (no-treatment) period because of 
concerns about the safety of the temporary concomitant use of TAK-385 with other 
therapies. However, subjects meeting the discontinuation criteria (Section 7.5) 
during the 28-day treatment period would not need to first pass through a 1-week 
observation period if they need to be switched to some other therapy immediately.
The treatment period in Part B was made 48 weeks long in order to investigate safety 
and efficacy over a longer period, in light of the fact that the safety and efficacy of 
TAK-385 in multiple dosing for 28 days will have been confirmed in Part A. If the 
investigator determines after 48 weeks that there are no safety problems and that 
TAK-385 treatment may be continued, then treatment may be continued for up to a 
total of 96 weeks. Part B was made an open-label phase with randomization to one 
of two doses the tolerability of which will have been confirmed in Part A. An open-
label study design was used because TAK-385 is being administered alone to 
hormone treatment-naive patient with prostate cancer. In addition, if a subject is 
going to be switched to some other treatment after the last dose of TAK-385 then, 
unlike in Part A, and assuming use in the actual clinical setting, it was decided that 
the other therapy could be initiated without any intervening observation period for 
confirming the safety of temporary concomitant use with the other therapy.
Furthermore, TAK-385 has been found to be affected by food, and the results that 
have been obtained suggest that TAK-385 absorption is decreased and delayed when 
a single dose is taken 30 minutes after food compared to when it is taken in a fasted 
condition (TAK-385_C27001). It was therefore decided that TAK-385 should be 
taken at least 30 minutes before breakfast.
Because the company plans to participate in multinational studies in the future, it was 
decided that Part B would be conducted using the same dosage and administration as 
that being used in the phase 2 studies being conducted overseas. Because Part B will 
be conducted using a dosage the tolerability of which will have been confirmed in 
Cohorts 1 and 2 in Part A, it was decided that Part A Cohort 3 and Part B could be 
conducted in parallel.
(2) Rationale for loading dose (Part A, Cohort 1)
In a phase 1 study in healthy adult males that was conducted in Europe 
(TAK-385_C27001), the tolerability of single doses as high as 360 mg and multiple
doses as high as 160 mg was confirmed. In order to keep serum testosterone at 
castration levels and maintain this effect, it was felt that a dose of at least TAK-385 
80 mg a day would be necessary as a maintenance dose. In addition, in study 
TAK-385_C27001, single doses of TAK-385 180 mg and above reduced serum 
testosterone levels to castration levels within 48 hours.


TAK-385 
TB-AK160108

Amendment 1
23 January 2015
CONFIDENTIAL
 
 
 
Based on these existing data on TAK-385 and on the development plan, it was 
decided that the loading dose for Cohort 1 in Part A of this study should be 320 mg, a 
dose that is within the range of doses that have been confirmed to be safe in single 
dosing, and that can be reliably expected to suppress serum testosterone levels within 
48 hours. Given that TAK-385 is going to be used in patients with prostate cancer, 
the company concluded that it would be necessary to use a dose that could be 
expected to be effective from the beginning, and that this dose would be tolerated as 
the loading dose in Japanese. The maintenance dose was set at 80 mg, which can be 
expected to suppress serum testosterone levels.
(3) Rationale for endpoints
1) Rationale for the primary endpoints
The endpoint in Part A is DLT, in order to confirm the tolerability of TAK-385 in 
multiple dosing. AEs, clinical laboratory tests, vital signs, and 12-lead ECGs 
were also made primary endpoints, in order to confirm safety.
In part B, the primary endpoints were made AEs, clinical laboratory tests, vital 
signs, and 12-lead ECGs, in order to confirm the safety of the use of TAK-385 in 
multiple dosing for 48 weeks.
2) Rationale for secondary endpoints
In both Part A and Part B, the plasma concentrations of unchanged TAK-385 will 
be investigated in order to confirm the PK of TAK-385 in multiple dosing. The 
change in serum testosterone levels over time will also be investigated, in order to 
confirm the pharmacodynamics. In addition, in Part B, PSA levels will also be 
evaluated in order to investigate the efficacy of TAK-385 in prostate cancer.
3) Rationale for other endpoints
In Part A, the changes over time in the blood levels of LH, FSH, DHT, and SHBG, 
which are involved in testosterone synthesis, will be investigated. PSA levels will 
also be evaluated, in order to preliminarily investigate the efficacy of TAK-385 in 
prostate cancer.
In Part B, disease progression assessed on the basis of PSA and disease 
progression assessed on the basis of imaging assessments will be evaluated in 
accordance with the Prostate Cancer Handling Guidelines, Fourth Edition [16], in 
order to preliminarily investigate the efficacy of TAK-385 in prostate cancer. In 


TAK-385 
TB-AK160108
Page 36 of 119
Amendment 1
23 January 2015
CONFIDENTIAL
addition, as in Part A, the changes over time in the blood levels of LH, FSH, DHT, 
and SHBG will also be investigated. Moreover, because androgen-deprivation 
therapy is known to promote loss of bone mineral density and increase the 
potential for bone fractures, bone density tests were specified in order to evaluate 
the effects of TAK-385 on bone mineral density. In nonclinical studies, changes 
suggesting systemic phospholipidosis have been found in the organs/tissues of 
animals. Therefore, in order to closely monitor subjects for phospholipidosis, 
ophthalmology tests were specified, as was assessment of the level of di-
docosahexaenoyl (22:6)-bis(monoacylglycero)phosphate (BMP) [14, 15]. 
Furthermore, in order to evaluate the effects of TAK-385 on quality of life in 
patients with prostate cancer, quality of life assessments will be performed using 
the Japanese versions of AMS, EORTC-QLQ-C30, and EPIC, which are widely 
used in clinical studies overseas.
6.3
Premature Termination or Suspension of Study or Investigational Site
6.3.1
Criteria for Premature Termination or Suspension of the Study
The study will be completed as planned unless one or more of the following criteria are 
satisfied that require temporary suspension or early termination of the study.


Significant violation of GCP that compromises the ability to achieve the primary 
study objectives or compromises subject safety.
6.3.2
Criteria for Premature Termination or Suspension of Investigational Sites
An investigational site may be terminated prematurely or suspended if the site (including 
the investigator) is found in significant violation of GCP, protocol, or contractual 
agreement, is unable to ensure adequate performance of the study, or as otherwise 
permitted by the contractual agreement.
6.3.3
Procedures for Premature Termination or Suspension of the Study or the 
Participation of Investigational Site(s)
In the event that the sponsor, an institutional review board (IRB)/independent ethics 
committee (IEC) or regulatory authority elects to terminate or suspend the study or the 
participation of an investigational site, a study-specific procedure for early termination or 
suspension will be provided by the sponsor; the procedure will be followed by applicable 
investigational sites during the course of termination or study suspension.

Food
From study treatment initiation and during the treatment period (in Part A, until the end

consumption of grapefruit and related beverages/foods will be prohibited unless judged 
necessary by the investigator.
7.4
Subject Management
1. Inpatient/outpatient status
Subjects will be admitted to the investigational site from one day before treatment 
initiation in each cohort (Day -1) until Day 15 in Part A. As a rule, from Day 16 on, 
the study will be conducted on an outpatient basis until the safety follow-up. 
However, from Day 27 on, if a subject lives far from the hospital and it would be 
difficult for the subject to come to the hospital at the scheduled times, or if the 
subject desires admission, the study may be conducted on an inpatient basis from 
Day 27 until Day 35 at the latest. While subjects are inpatients in Part A, they will eat 
meals (breakfast, lunch, and dinner) at specified times. After being discharged as 
well, subjects will be instructed to avoid eating or drinking excessively until the end 
of safety follow-up. When subjects are coming in for visits on an outpatient basis, 
they will be instructed to be sure to eat dinner on the day before the day of a visit at 
which a blood sample will be collected for laboratory testing, and they will be 
instructed to return to the hospital on the following day without eating for blood 
collection and testing, after which they will receive TAK-385 and then eat breakfast 
at least 30 minutes later.
If a subject desires to return home temporarily during the inpatient period, and it 
would not interfere with study treatment, observations, or tests, then the investigator 
may allow the subject to return home temporarily, after carefully checking to be sure 
that the subject’s condition is stable, on the basis of the data that have been collected 
during the study to that point.
Unless there is a special reason, Part B will as a rule be conducted on an outpatient 
basis. Subjects will be instructed to observe the scheduled visit times and undergo 
the examinations and the specified tests. Subjects will also be instructed to inform 
the investigator promptly if they are not able to come in for a scheduled visit.
2. Study treatment
Investigators will instruct subjects to take the study drug 30 minutes before breakfast 
on each day, and to make sure that the time they take the study drug is the same on 
each day, to the extent possible.
If a subject forgets to take the study drug 30 minutes before breakfast, the subject 
should take the drug 30 minutes before lunch on the same day. If a subject forgets to 
take the study drug both 30 minutes before breakfast and 30 minutes before lunch, 
the subject should take the study drug 30 minutes before dinner on the same day. It 
will be explained to subjects that they should not take any study drug that they have 
forgotten to take on a later day together with the study drug for that day. Subjects 


TAK-385

will also be instructed to be sure to note in the patient diary the time they took the 
study drug as well as whether or not they took the study drug 30 minutes before 
breakfast.
On scheduled outpatient visit days, subjects will be asked to come to the 
investigational site in the morning without taking the study drug, and the scheduled 
tests will be performed.
3. Drinks, etc.
On days on which study drug is to be taken, subjects will be prohibited from drinking 
anything from 1 hour before dosing until 30 minutes after, other than one cup of 
water when they take the study drug.
4. Other
Investigators will instruct subjects that, if a subjective symptom emerges, it should 
be reported, along with the date of onset, severity, outcome, and date of outcome, 
when the subject next visits the investigational site.
Investigators will instruct subjects not to take any drugs, including over-the-counter 
drugs, other than the drugs that they are instructed to take, without consulting the 
investigator in advance.
Subjects will be instructed that, if they are treated at another medical institution in 
the time between the treatment period and the safety follow-up, they are to report the 
background for and nature of said treatment to the investigator, and to inform the 
medical institution in question that they are participating in a clinical study.
7.5
Criteria for Discontinuation or Withdrawal of a Subject
Investigators will enter into the electronic case report form (eCRF) the primary reason for 
discontinuation or withdrawal of the subject from the study, classified into one of the 
following categories. See Section 9.1.23 for subjects discontinuing before the study 
treatment initiation (in the case of Part A) or before randomization (in the case of Part B).
1.
Pretreatment event or adverse event
This will be considered the primary reason if the subject has experienced a PTE or 
AE that requires early termination because continued participation imposes an 
unacceptable risk to the subject’s health or the subject is unwilling to continue 
because of the PTE or AE; if a serious AE occurs, the subject temporarily stops 
taking the study drug, and the AE recurs following study treatment resumption, or 
does not resolve event after 2 weeks of treatment interruption; or if toxicity that is 
considered DLT occurs in Part A.
Liver function test abnormalities
If a LFT abnormality meeting any of the following criteria occurs during study 
treatment, study drug administration will be discontinued immediately, and 
appropriate follow-up tests will be performed until the subject’s clinical laboratory 
profile returns to normal, to the level of the first test value obtained after informed 


TAK-385

consent (in the case of a PTE), or to baseline (in the case of an AE) (see Section 
9.1.8).
-
ALT or AST > 3 ULN; AND total bilirubin > 2 ULN or PT-INR > 1.5
2.
Major protocol deviation
This will be considered the primary reason for study withdrawal if it is discovered 
after the first dose of study treatment (in the case of Part A) or after randomization 
(in the case of Part B) that the subject does not meet the enrollment criteria specified 
in the study protocol, or has not followed the study protocol, and that continuing the
study would pose an unacceptable risk to the subject's health.
3.
Lost to Follow-up
This will be considered the primary reason for study withdrawal if a subject fails a 
study visit and cannot be contacted. In this case, the fact that contact was attempted 
will be noted in the source documents.
4.
Voluntary withdrawal
This will be considered the primary reason for withdrawal if the subject wishes to 
withdraw from the study. The reason for withdrawal, if provided, should be recorded 
in the eCRF.
Note: All attempts should be made to determine the underlying reason for the 
withdrawal and, where possible, the primary underlying reason should be recorded 
(ie, withdrawal due to an AE or lack of efficacy should not be recorded in the 
“voluntary withdrawal” category).
5.
Study termination
This will be considered the primary reason for withdrawal if the sponsor, IRB, or 
regulatory authorities decide to terminate the study.
6.
Lack of efficacy
This will be considered the primary reason for withdrawal if the expected level of 
efficacy is not obtained because of disease progression assessed by PSA level or 
evaluation of soft tissue or bone lesions by diagnostic imaging (according to the 
Prostate Cancer Handling Guidelines, Fourth Edition [16]), or if the decrease in 
serum testosterone meets any of the following criteria.
1) If, in Part A, serum testosterone does not drop below 50 ng/dL at 2 or more time 
points at least 7 days apart following treatment initiation, and it is determined as 
a result that the patient must be switched to some other therapy.
2) If, in Part B, serum testosterone does not drop below 50 ng/dL by 4 weeks after 
uptitration based on the uptitration criteria (see Section 8.1.3.1).
3) If, in Part B, serum testosterone exceeds 50 ng/dL on 2 consecutive occasions, or 
on 3 occasions in total, whether consecutive or not, by 9 weeks (57 days) after 
the start of treatment following uptitration in accordance with the uptitration 
guidelines (see Section 8.1.3.1).

subject from the study. Furthermore, subjects may withdraw from the study without 
providing a reason at any time during the study. If a subject withdraws from the study, 
the investigator will enter the primary reason for withdrawal in the eCRF, and will 
perform all procedures scheduled for the Early Termination Visit.

The specified dose of TAK-385 will be taken once a day orally with 1 cup of water at 
least 30 minutes before breakfast. Except for when various tests are being performed or 
an AE occurs, an effort will be made to ensure that subjects rest for 2 hours after 
receiving the dose.
The investigator or study support staff will check to make sure that all specified study 
drug has been taken.
8.1.3.1
Criteria for Upward Dose Adjustments
Part A: The dose of TAK-385 will not be increased even if inadequate testosterone 
suppression occurs (< 50 ng/dL). If after treatment initiation the serum testosterone level 
does not drop below 50 ng/dL at 2 or more time points separated by at least 7 days and 
the investigator or sub-investigator determines that the patient needs to be switched to 
some other treatment, then TAK-385 treatment will be stopped and the patient withdrawn 
from the study.

CONFIDENTIAL
Part B: If the following conditions are met, the dose may be adjusted, taking efficacy and 
safety into consideration. Dose adjustment will be performed when the subject is 
examined by the investigator or sub-investigator.
If the serum testosterone level in an individual patient exceeds 50 ng/dL at Week 5 (Day 
29), Week 9 (Day 57), or Week 13 (Day 85), following review of compliance, a one-time 
upward dose modification (increment of 40 mg daily) will be allowed. After Week 13, 
the dose will not be increased even if the serum testosterone level exceeds 50 ng/dL.
The dose will not be increased in the 120 mg group before the DLT evaluations have been 
completed for Cohort 3 in Part A, or if the dose has not been found to be tolerable. 
Similarly, if tolerability is not found in Cohort 2 in Part A and a 40 mg group is therefore 
going to be used instead of a 120 mg group, then the dose in the 80 mg group will not be 
increased.
8.1.3.2
Criteria for Dose Holds and Dose Reduction
Part A: If a treatment-related AE occurs, or if it would be difficult to continue with 
TAK-385 treatment, then the dose of TAK-385 will not be reduced, and study treatment 
will be interrupted if necessary.
Part B: If a treatment-related AE occurs or if it would be difficult to continue with 
TAK-385 treatment, then study treatment will be interrupted if necessary. Subjects who 
experience serious AEs requiring study treatment interruption within 12 weeks (84 days) 
following treatment initiation may have their doses reduced by one dose level – 40 mg –
following a 2-week treatment interruption period. If the AE continues even after dose 
reduction, or the subject’s serum testosterone level exceeds 50 ng/dL for 4 to 6 weeks 
following dose reduction, then TAK-385 treatment will be discontinued so that the 
subject may receive some other therapy. If a serious AE requiring study treatment 
interruption occurs on or after Week 13 (Day 85) following treatment initiation, and the 
subject’s treatment has not been interrupted prior to that, then the subject’s treatment may 
be interrupted for 2 weeks and then resumed. However, if the AE recurs following study 
treatment resumption, or if the AE does not resolve even after 2 weeks of treatment 
interruption, then the subject will be withdrawn from the study.
Even if the dose has been increased in accordance with Section 8.1.3.1, when reducing 
the dose, it will be reduced by one dose level. Dose reduction will not be performed for 
subjects in the 40 mg group. In addition, if the dose is reduced in accordance with this 
section, then the dose may not be increased as described in Section 8.1.3.1.
Furthermore, if a LFT abnormality is found, it will be handled as shown in Table 8.c.

Overdose
An overdose is defined as a known deliberate or accidental administration of 
investigational drug, to or by a study subject, at a dose above that which is assigned to 
that individual subject according to the study protocol.
All cases of overdose (with or without associated AEs) will be documented on an 
Overdose page of the eCRF, in order to capture this important safety information 
consistently in the database. Cases of overdose without manifested signs or symptoms are 
not considered AEs. AEs associated with an overdose will be documented on AE CRF(s) 
according to Section 10.0.
Serious AEs associated with overdose should be reported according to the procedures 
outlined in Section 10.2.2.
In the event of a study drug overdose, the investigator will treat the subject 
symptomatically.

Study Drug Allocation and Prescribing Procedures
In Part A, in order to confirm eligibility for study participation based on the screening 
tests, the investigator or a person designated by the investigator will contact the 
registration center by fax. The investigator will prescribe study drug to the subject after 
confirming that the subject is eligible for the study based on a fax received from the 
registration center.
In Part B, the investigator or a person designated by the investigator will contact the 
registration center by fax to confirm the subject’s eligibility at the start of the treatment 
period.  After confirming, on the basis of a fax received from the registration center, that 
the subject is eligible, the investigator will prescribe the subject the study drug for the 
group to which the subject has been assigned. The investigator or a person designated by 
the investigator will enter the group to which the subject has been assigned in the eCRF.
Subjects will be assigned a 4-digit number, with the first signifying the Part and Cohort, 
the second signifying the investigational site, and the last two digits constituting a series 
number within the cohort at the investigational site. This 4-digit number will be used by 
the investigational sites to identify the specimens that will be used to assess the PK and 
pharmacodynamics. These numbers will be noted on the specimen tubes that are 
provided for measurement, and will be used instead of the subject identification numbers 
for reporting the measurement results. These numbers will not be replaced by the last 3 
digits of the subject identification numbers.
8.3
Randomization Code Creation and Storage
The randomization manager (or a person designated by the study sponsor) will prepare a 
randomization table. The randomization information will be stored in a safe location, and 
will only be accessible to authorized personnel.
8.4
Control and Disposal of Drugs Provided by the Study Sponsor
The study drug controller will receive the written procedures prepared by the study 
sponsor specifying the handling, storage, and control of study drug, and will 
appropriately control the drugs provided by the study sponsor in accordance with these 
written procedures. The investigators will also receive these procedures from the study 
sponsor. These procedures will describe the procedures that will have to be followed to 
ensure that the receipt, handling, storage, control, and prescribing of the study drugs 
provided by the study sponsor, as well as the recovery of unused drugs from subjects and 
their return to the study sponsor, or their disposal, are carried out appropriately and 
reliably.
The study drug controlled will promptly return to the study sponsor any unused drugs 
once the study has been completed at the investigational site in question.

Study Proceduress
The following sections describe the study procedures and data to be collected. In 
principle, the same investigator will perform examinations and testing, observations, and 
evaluations of subjects. The Schedule of Study Procedures is shown in Appendix A to 
Appendix E.
9.1.1
Informed Consent
The requirements of the informed consent are described in Section 15.2.
Informed consent must be obtained from the subject before any protocol-directed 
procedures are performed.
A unique subject identification number will be assigned to each subject at the time that 
informed consent is explained. The same subject number will be used throughout the 
study.
Informed Consent for Pharmacogenomics
Informed consent for the storage and banking of the blood sample for pharmacogenomics 
(PGx) testing in this study must be obtained separately before collection. The provision 
of consent to collect and analyze the PGx sample is independent of consent to the other 
aspects of the study.
9.1.2

comorbidity (concurrent medical condition) (see Section 9.1.18).
Previous therapeutic drugs used (medication history) will include all drugs that were 
discontinued within 28 days before the date of informed consent and are relevant to the 
eligibility criteria.
9.1.3
Physical Examination
A physical examination will be conducted for the parts of the body listed below 
(interview, visual inspection, auscultation, palpation, percussion, etc.).
(1) eyes, (2) ears, nose, and throat, (3) cardiovascular system, (4) respiratory organs, 
(5) digestive organs, (6) skin, (7) extremities, (8) musculoskeletal system, (9) nervous 
system, (10) lymph nodes, (11) urogenital organs, (12) other
The investigator will evaluate abnormal findings discovered in the pre-administration 
physical examination for clinical relevance and record the results in the source data. 
Findings and changes considered to be clinically relevant will be input as PTEs or 
comorbidities at the proper locations in the source data and eCRF as described in 
Sections 10.0 and 9.1.18.
9.1.4
Weight, Height, and ECOG Performance Status
Weight and height will be measured. Weight will be measured in kilograms to the first 
decimal place, and height will be measured in centimeters to the closest integer. In 
addition, the ECOG performance status will be measured in accordance with Appendix G.
9.1.5
Vital Signs
Measurement of vital signs will include temperature (axillary), seated blood pressure 
(systolic and diastolic after resting at least 5 min) and heart rate (bpm). Measurements 
will be taken after the subject has been sitting for 5 min.
9.1.6
Electrocardiogram
A 12-lead ECG will be performed. Measurements will be taken after the subject has been 
in supine position for 5 min. The investigator (or a specialist at the medical institution) 
will assess the results by the following categories: Normal range ("Within Normal 
Limits"), Abnormal but not clinically significant ("Abnormal, Not Clinically Significant
"), or Abnormal and clinically significant ("Clinically Significant ").
The following parameters will be transferred from the subject's ECG recording to the 
eCRF: heart rate, QT interval, PR interval, QRS duration, and RR interval.
In determining the QTc value, Bazett corrected QT (QTcB) and QTcF will be calculated 
using the Bazett formula (QT/RR0.5) and Fridericia formula (QT/RR0.33), respectively.
9.1.7
Imaging Assessment
CT or MRI (thoracic, abdominal, and pelvic regions) and bone scintigraphy will be 
performed during screening to verify that there are no distant metastatic lesions. If

measurements were taken within 28 days before the start of study drug administration, 
the results of diagnostic imaging and tests conducted before obtaining informed consent 
can be used. CT or MRI and bone scintigraphy will also be performed on the days 
stipulated in the clinical trial schedule (Appendix A to Appendix C) to check for new 
lesions. Disease progression will be determined by the presence or absence of new 
lesions based on the items evaluated in diagnostic imaging. Diagnostic imaging will also 
be performed as needed in Part A if abnormal findings appear in other tests and 
examinations during administration of the study drug.
9.1.8
Clinical Laboratory Tests
Specimens will be handled according to the procedures described in a separate document. 
A general guideline for the total amount of blood to be collected in this study is shown in 
Section 9.5.
Samples for clinical laboratory tests will be collected after at least 10 hours of fasting on 
the days stipulated in the Schedule of Study Procedures (Appendix A to Appendix E).

The above clinical laboratory tests will be performed at the medical institution. The 
investigator will evaluate and archive reported clinical laboratory test findings.
When the ALT or AST levels are > 3 ULN, retesting (at least ALP, ALT, AST, total 
bilirubin, γ-GTP, and PT-INR) will be performed within 48 to 72 hours (within 7 days at 
the latest).
(See Section 7.5 for the criteria for the withdrawal from the study.  See Section 10.2.3 for 
the reporting of LFT abnormalities in cases where the ALT or AST level exceeds 3 
ULN, and the total bilirubin level exceeds 2 ULN or the PT-INR exceeds 1.5.)
The investigator will archive the reference ranges for the clinical laboratory tests, 
including the history.
All clinically relevant, abnormal laboratory test values will be input in the source data 
and eCRF of the subject as AEs, etc. All clinically relevant, abnormal laboratory test 
values verified by retesting will be followed up in all subjects until the abnormal value 
returns to an acceptable level or there is a sufficient explanation for the observed change.
9.1.9
Cardiac Tests
CK-MB and cardiac troponin T will be measured at the institution during screening. 
These measurements will also be performed as needed when abnormal findings appear in 
other tests and examinations during administration of the study drug.
9.1.10
Tumor Marker
PSA will be measured by a third-party organization according to a separately prepared 
written procedure. Progression of disease as indicated by PSA (based on the Prostate 
Cancer Handling Guidelines, 4th Edition [16]) is defined as an increase of at least 25% in 
the PSA value measured at least 4 weeks after the minimum PSA value measured during 
the study period (at least 12 weeks if the minimum value was recorded during screening). 
In such a case, the amount of increase must be at least 2 ng/mL. The date this condition 
is met will be considered the disease progression date.
9.1.11
Collection of Pharmacogenomic Sample
After the start of study drug administration (Part A) or after randomization (Part B), one 
sample for PGx testing will be collected as early as possible during the administration 
period. A sample of 5 mL of whole blood for DNA extraction will be collected in an 
EDTA-treated polypropylene tube from each subject who has given consent. The sample 
will be sent to the sample storage facility.
Details of collection, handling, and storage of the sample for PGx testing will be carried 
out according to a separately prepared written procedure.

Bone mineral density will be measured by dual-energy X-ray absorptiometry (DXA). 
Throughout the study period the same subject will be measured on the same model of 
equipment using the same scanning mode. The investigator will input the equipment 
model, date of measurement, and results for the following measurement parameters into 
the eCRF.
Measurement sites: Lumbar 2 to 4 (L2 to L4) and hip (femoral neck, femoral trochanteric, 
femoral intertrochanteric, Ward's triangle, and total) 
Measurement parameters: Bone mineral content (BMC, g), bone area (Area, cm2), and 
bone mineral density (BMD, g/cm2) of L2, L3, and L4, femoral neck, femoral 
trochanteric, and femoral intertrochanteric regions, and Ward's triangle; and total bone 
mineral content (BMC, g) (combined), bone area (Area, cm2) (combined), and bone 
mineral density (BMD g/cm2) (Mean) of L2 to L4 and hip.
9.1.13
Ophthalmological Examination (Part B Only)
The examination will be carried out in a darkened room. A slit lamp microscope will be 
used to examine the anterior of the eye, and the results will be classified as follows: 
Normal range, Abnormal but not clinically significant, or Abnormal and clinically 
significant.
9.1.14
BMP Concentrations (Part B Only)
BMP will be measured in serum and urine samples by a third-party organization 
according to a separately prepared written procedure. Sequential BMP testing will not be 
performed, and the measurements will be summarized after a fixed time period.  
Measurements will be conducted when there are clinical findings suggesting an 
association with phospholipidosis or there is a report of an association between 
comparable GnRH antagonists and phospholipidosis.
9.1.15
QOL Assessment (Part B Only)
QOL will be assessed using AMS, EORTC-QLQ-C30, and EPIC scores. After arriving at 
the hospital each subject will personally fill in the form provided by the sponsor before 
other tests are conducted and before the study drug is administered. The scoring of QOL 
will be carried out in the order: AMS, EORTC-QLQ-C30, and EPIC.
9.1.16
Concomitant Medications
The term concomitant medication is refers to any drug given in addition to the study drug. 
These may be prescribed by a physician or obtained by the subject over the counter. At 
each study visit, subjects will be asked whether they have taken any medication other 
than the study drug (used from signing of informed consent through safety follow-up), 
and all medication including vitamin supplements, over-the-counter medications, and oral 
herbal preparations, must be recorded in the eCRF.

At each study visit, subjects will be asked whether they have received any therapeutic 
procedures (performed from signing of informed consent through safety follow-up).
9.1.18
Concurrent Medical Conditions
Concurrent medical conditions are those significant ongoing conditions or diseases that 
are present at signing of informed consent. This includes clinically significant laboratory, 
ECG, or physical examination abnormalities noted at screening examinations. The details 
of the condition (ie, diagnosis) should be recorded in the eCRF.
9.1.19
Contraception
Male subjects with female partners who may become pregnant will use a barrier-type 
contraceptive device (eg, condom and spermicidal cream or jelly) from the time of 
informed consent until 4 months after the final dose of the study drug. Furthermore, the 
subject will be instructed not to donate sperm during this time frame.
9.1.20
Pregnancy
If the subject's female partner becomes pregnant, the investigator, with the female 
partner's consent, will inform her attending physician (obstetrician) that the subject was 
participating in a clinical study when she became pregnant and reveal the details of the 
study drug.
If a pregnancy is reported for any subject, the investigator, with the subject's consent, will 
carry out a follow-up investigation until delivery, including premature delivery, and make 
a report to the sponsor using the designated follow-up form. The investigator will also 
conduct a postnatal evaluation.
9.1.21
Pharmacokinetic Assessments
The plasma concentrations will be measured at each blood sample collection time point 
(see Appendix D and Appendix E) in accordance with separately prepared written 
procedures.
The 3 time points for TAK-385 dosing that immediately precede blood sample collection, 
and the time points for the collection of blood samples for pharmacokinetic assessment,

Documentation of Study Enrollment/Randomization
In Part A, only subjects who meet all of the inclusion criteria and do not meet any of the 
exclusion criteria will be enrolled in the treatment period. If a subject cannot proceed to 
the treatment period, the investigator will enter the primary reason for this in the eCRF.
In Part B, only subjects who meet all of the inclusion criteria and do not meet any of the 
exclusion criteria will be randomized. If a subject cannot be randomized, the investigator 
will enter the primary reason for this in the eCRF.
9.2
Monitoring Subject Treatment Compliance
During the inpatient period in Part A, the investigator or a person designated by the 
investigator will give the subject the study drug, confirm that the subject has taken it, and 
record this in the source documents. For study drug administration following discharge 
from the investigational site, subjects will be instructed to take the drug appropriately.
On the day of the first dose in Part B, the investigator or a person designated by the 
investigator will administer the study drug to the subject, confirm that the subject has 
taken the drug, and record this in the source documents. For study drug administration 
from Day 2 on, subjects will be instructed to take the drug appropriately.
The day of treatment initiation, the day of treatment completion, the dose, the actions 
taken with respect to the dose, and the reasons for any changes will be entered in both the 
source documents and the eCRF.

Subjects will be instructed to bring their study drug (bottles) in with them at each 
outpatient visit. If it is found that a subject has not complied with the study treatment in 
the time since the previous visit (eg, if 20% [6 doses] or more of the specified doses have 
not been taken), then the subject may be withdrawn from the study. If the subject is 
given instructions about treatment noncompliance, then this will be recorded in the 
source documents.

Handling After the End of the Study
Study drug will not be supplied to subjects who have completed the study treatment 
period and the continuation treatment period (Part B).
9.4
Biological Sample Storage and Disposal
The 5 mL samples of whole blood collected for PGx research will be stored frozen at the 
sample storage facility (Protocol Annex 1).
The storage period will be 20 years from the day the samples for PGx research were 
initially collected in this study.
During the sample storage period, if a subject wants his samples destroyed, the 
investigational site will ask, via the study sponsor, and in accordance with the specified 
procedures, the sample storage facility to destroy the subject’s samples. The sample 
storage facility will destroy the samples in questions in accordance with the procedures, 
and will inform the investigational site and the study sponsor that the samples have been 
destroyed. However, if the data that allow the subject to be identified (eg, medical 
records) have been destroyed once the study has been completed, and it is therefore no 
longer possible to link the subject to his samples, then the samples will not be destroyed.
Even if the samples can be tied to the subject, if the PGx investigation has already been 
performed, the remaining samples will be destroyed, but the anonymized results of the 
PGx investigation will be retained by the study sponsor.
The study sponsor will construct the administrative structure necessary to protect 
subjects’ personal information, and will stipulate in advance criteria for handling sample 
collection, storage, and disposal, as well as prepare the necessary written procedures.

PRETREATMENT EVENTS AND ADVERSE EVENTS
10.1
Definition
10.1.1
Pretreatment Events
A PTE is defined as any untoward medical occurrence in a clinical investigation subject 
who has signed informed consent to participate in a study but prior to administration of 
any study drug; it does not necessarily have to have a causal relationship with study 
participation.
10.1.2
Adverse Events
An AE is defined as any untoward medical occurrence in a clinical investigation subject 
administered a drug (including study drug); it does not necessarily have to have a causal 
relationship with this treatment.
An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant 
abnormal laboratory finding), symptom, or disease temporally associated with the use of 
a drug whether or not it is considered related to the drug.
10.1.3
Additional Points to Consider for Pretreatment Events and Adverse Events
An untoward findings generally may:

Indicate a new diagnosis or unexpected worsening of a pre-existing condition.
(Intermittent events for pre existing conditions underlying disease should not be 
considered PTEs or AEs.)

Require therapeutic intervention

Require an invasive diagnostic procedure

Require discontinuation or a change in dose of study drug or concomitant medication

Be considered unfavorable by the investigator for any reason.
Diagnosis vs signs and symptoms:
Each event should be recorded to represent a single diagnosis. Accompanying signs 
(including abnormal laboratory values or ECG findings) or symptoms should NOT be 
recorded as additional AEs. If a diagnosis is unknown, sign(s) and/or symptom(s) should 
be recorded appropriately as a PTE(s) or as an AE(s).
Laboratory values and ECG findings:
Change in laboratory value or ECG parameters are only considered to be PTEs or AEs if 
they are judged to be clinically significant (ie, if some action or intervention is required, 
or if the investigators judges the change to be beyond the normal physiological 
fluctuation). A laboratory re-test and/or continued monitoring of an abnormal value are
not considered an intervention. In addition, repeated or additional noninvasive testing for 
verification, evaluation, or monitoring of an abnormality is not considered an intervention.


TAK-385 
TB-AK160108
Page 67 of 119
Amendment 1
23 January 2015
CONFIDENTIAL
If abnormal laboratory values or ECG findings are the result of pathology for which there 
is an overall diagnosis (eg, increased creatinine in renal impairment), the diagnosis only 
should be reported appropriately as a PTE or as an AE.
Pre-existing conditions (disease or symptoms existing before informed consent is 
obtained):
Pre-existing conditions (present at the time of signing of informed consent) are 
considered concurrent medical conditions and should NOT be recorded as PTEs or AEs. 
Abnormalities found in initial tests and observations (eg, laboratory tests, ECG, and 
radiology) after informed consent should NOT be recorded as PTEs unless related to 
study procedures, except that abnormalities occurring as a result of initial test or 
observation procedures (such as internal bleeding during blood draw) will be recorded as 
PTEs in the eCRF. If the subject experiences a worsening or complication of such a 
concurrent condition, the worsening or complication should be recorded appropriately as 
a PTE (worsening or complication occurs before start of study drug) or an AE (worsening 
or complication occurs after start of study drug). Investigators should ensure that the 
event term recorded captures the change in the condition (eg, "worsening of 
hypertension").
If a subject has a pre-existing episodic condition (eg, asthma, epilepsy) that increase in 
frequency or become serious or severe should be recorded as PTEs/AEs. Symptoms that 
worsen more than expected in subjects with chronic disease (eg, cataracts, rheumatoid 
arthritis) should also be recorded as PTEs/AEs. Investigators should ensure that the AE 
term recorded captures the changes in the condition from Baseline (eg, "worsening of 
XX").
Worsening of PTEs or AEs:
If the subject experiences a worsening or complication of a PTE after starting 
administration of the study drug or experiences signs/symptoms that occur secondarily to 
PTEs, the worsening or complication should be recorded appropriately as an AEs in the 
eCRF. Investigators should ensure that the AE term recorded captures the change in the 
condition (eg, "worsening of XX").
If the subject experiences a worsening or complication of an AE after any change in study 
drug, the worsening or complication should be recorded as a new AE in the eCRF. 
Investigators should ensure that the AE term recorded captures the change in the 
condition (eg, "worsening of XX").
Underlying disease:
In this study, worsening of the underlying disease will not be handled as an AE. The 
onset or worsening of symptoms associated with progression of the underlying disease 
will be handled as an AE.
Planned surgeries or procedures:
Preplanned procedures (surgelies or therapies) that were scheduled prior to signing of 
informed consent were not considered PTEs or AEs, except that any conditions and 
events associated with the worsening of pre-existing conditions requiring those 
procedures to be undertaken on an emergency basis should be captured appropriately as a 


TAK-385 
TB-AK160108
Page 68 of 119
Amendment 1
23 January 2015
CONFIDENTIAL
PTE or an AE. Complications resulting from any planned surgery should be reported as 
AEs.
Elective surgeries or procedures:
Elective procedures performed where there is no change in the subject's medical 
condition should not be recorded as PTEs or AEs, but should be documented in the 
subject's source documents. Complications resulting from an elective surgery should be 
reported as AEs.
Insufficient clinical response (lack of efficacy):
Insufficient clinical response, efficacy, or pharmacological effect should NOT be 
recorded as an AE. Investigators must make a distinction between worsening of 
preexisting symptoms and lack of efficacy.
Overdose:
Cases of overdose with any medication without manifested side effects are NOT 
considered PTEs or AEs, but overdoses will be recorded on an overdose page of the 
eCRF.  Any manifested side effects will be considered AEs and will be recorded on the 
AE page of the eCRF.
10.1.4
Serious Adverse Events
A serious AE is defined as any untoward medical occurrence that at any dose:
1.
Results in DEATH.
2.
Is LIFE-THREATENING*.
3.
Requires inpatient HOSPITALIZATION or prolongation of existing 
hospitalization.
4.
Results in persistent or significant DISABILITY/INCAPACITY.
5.
Leads to a CONGENITAL ANOMALY/BIRTH DEFECT.
6.
Is an IMPORTANT MEDICAL EVENT that satisfies any of the following:
•
May require intervention to prevent items 1 through 5 above.
•
May expose the subject to danger, even though the event is not immediately 
life threatening or fatal or does not result in hospitalization.
•
Includes any event or synonym described in the Takeda Medically Significant 
AE List (Table 10.a).
* The term "life threatening" refers to an event in which the subject is at risk of death at the time of the 
event; it does not refer to an event that hypothetically might have caused death if it was more severe.

PTEs that fulfill 1 or more of the serious criteria above are also to be considered SAEs 
and should be reported by the same procedures as for SAEs (see Sections 10.2.2 and 
10.3).
10.1.5
Special Interest Adverse Events
A special interest AE (whether serious or not) is one of specific and medical concern 
specific to the study drug or program. Investigators will monitor subjects on an ongoing 
basis for such events, and the sponsor will be notified immediately of any that occur. 
Further investigation may sometimes be necessary to establish assessment of these events.
Refer to Section 10.2.1.3 for the methods and deadlines for reports to the sponsor by 
investigators.
10.1.5.1
Liver Function Test Abnormalities
LFT abnormalities were identified as specific AEs because nonclinical studies in 
monkeys revealed LFT abnormalities and because clinical studies on oral GnRH 
antagonists with the same backbone structure as TAK-385 have revealed elevated AST 
and ALT as common treatment-related AEs.
The management of LFT abnormality AEs is presented in Table 8.c of the protocol.
When ALT or AST levels are > 3 ULN, retesting will be performed within 48 to 72 
hours (within 7 days at the latest). As soon as they become aware that ALT or AST levels 
are > 3 ULN, investigators will discuss detailed information on affected subjects and 
other potential causes with the sponsor to review whether the administration of study 
drug should be discontinued immediately.
If ALT or AST levels are > 3 ULN and total bilirubin levels are > 2 ULN or the PT-
INR is > 1.5, and investigators conclude that the levels cannot be explained by any factor 
other that study drug based on the results of retesting, then they will be handled as serious 
AEs.


TAK-385 
TB-AK160108

Amendment 1

CONFIDENTIAL
When LFT abnormalities correspond to the criteria in Section 7.5, investigators will 
immediately discontinue administration of study drug and will perform appropriate 
follow-up.
10.1.6
Severity of Pretreatment Events and Adverse Events
The severity of AEs, including laboratory abnormalities, will be determined according to 
the CTCAE. Events not covered in the CTCAE will be classified and defined as follows.
Grade 1
Mild;*1 asymptomatic or mild symptoms; clinical or diagnostic observations only; 
intervention not indicated
Grade 2
Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate 
instrumental ADL*2
Grade 3
Severe or medically significant but not immediately life-threatening; hospitalization or 
prolongation of hospitalization indicated; disabling; limited self care ADL*3
Grade 4
Life-threatening consequences; urgent intervention indicated
Grade 5
Death related to AE
*1: A semi-colon indicates 'or' within the description of the grade.
*2: Instrumental ADL refer to preparing meals, shopping for groceries or clothes, using the telephone, 
managing money, etc.
*3: Self care ADL refer to bathing, dressing and undressing, feeding self, using the toilet, taking 
medications, and not bedridden.
AEs that undergo a change in severity for the worse will be individually recorded in the 
eCRF as separate AEs.
Clarification should be made between a serious AE and an AE that is considered severe in 
intensity (Grade 3 or 4), because the terms serious and severe are NOT synonymous. The 
term "severe" is often used to describe the intensity (severity) of a specific event, but the 
event itself may be of relatively minor medical significance (such as a Grade 3 headache). 
This is NOT the same as "serious." For example, a white blood cell count of 1000 to 
2000/mm3 is considered Grade 3 (severe) but may not necessarily be considered serious. 
Seriousness (not intensity) serves as a guide for defining regulatory reporting obligations.
10.1.7
Causality of Adverse Events
The relationships of each AEs to study drug will be assessed using the following 
categories:
Related
An AE that follows a reasonable temporal sequence from administration of a drug (including 
the course after withdrawal of the drug), or for which possible involvement of the drug can 
be argued, although factors other than the drug, such as underlying diseases, complications, 
concomitant medications and concomitant therapies, may also be responsible.
Not related
An AE that does not follow a reasonable temporal sequence from administration of a drug 
and/or that can reasonably be explained by other factors, such as underlying diseases, 
complications, concomitant medications and concomitant therapies.

Amendment 1
23 January 2015
CONFIDENTIAL
10.1.8
Relationship to Study Procedures
The relationship should be assessed as Related if the investigator considers that there is 
reasonable possibility that an event is due to a study procedure. Otherwise, the 
relationship should be assessed as Not Related.
10.1.9
Date of Onset
The date of AE onset (the start date of the AE/PTE) will be determined based on the 
following criteria.
AEs
Date of onset
Signs, symptoms, disease (diagnosis)
The date on which the subject or investigators first notice the signs 
or symptoms of an AE will be recorded.
Asymptomatic disease
The date on which a diagnostic test is conducted and the diagnosis 
is confirmed will be recorded.
The date on which diagnosis is confirmed will be recorded even 
when test findings belatedly reveal older findings or when the time 
of onset can be generally estimated.
Worsening of complications or PTEs
The date on which the subject or investigators first notice 
worsening of signs or symptoms will be recorded.
When initial test results after 
informed consent are normal but 
subsequent test results are abnormal 
(PTE)
When test results turn abnormal after 
start of study drug treatment (AEs)
The date on which laboratory abnormalities considered clinically 
significant are found will be recorded.
When test results after informed 
consent are initially normal but then 
worsen (PTE)
When test results at start of study 
drug treatment are abnormal and then 
worsen (AE)
The date of tests on which laboratory profiles reveal clear increases 
or decreases based on clinical judgment.
10.1.10 Date Resolved
The date resolved (the stop date of the AE/PTE) is the date on which AEs resolve 
(including resolved with sequelae). When AEs result in death, the date of death will be 
used. When an AE is recorded as a separate AE in the eCRF due to worsening of severity, 
the day before the date on which worsening was confirmed will be recorded as the date of 
resolution. Cases in which resolution cannot be confirmed at the end of the study will be 
assessed as ongoing.
10.1.11 Frequency
When an AE that apparently resolves and occurs repeatedly (such as constipation, 
diarrhea, and vomiting) is determined by investigators to be a series of occurrences 
constituting a single event over the period of time from initial onset to ultimate resolution, 
the incidence will be considered "intermittent." All other cases will be handled as 
"continuous."

10.1.12 Action Taken for Study Drug
Actions taken for study drug will be classified and defined as follows.
Drug Withdrawn
A study drug is terminated due to the particular AE (including when subjects 
themselves decide to discontinue).
Dose not Changed
The particular AE did not require any dose change of study drug.
Discontinuation of study drug, dose reduction, or dose escalation due to AE other 
than the AE in question will be handled as "dose not changed."
Discontinuation of study drug or dose reduction for reasons other than action taken 
for the AE, such as subject carelessness, will be handled as "dose not changed."
Unknown
When subjects cannot be contacted and the course after the date of onset cannot be 
ascertained, etc.
Not Applicable
When study drug treatment has already been completed or discontinued at the time 
that the AE occurs
Dose Reduced
A reduction in study drug dose as action taken for the AE will be handled as "dose 
reduced"(the dose cannot be reduced at the subject's discretion)
Dose Increased
An escalation in study drug dose as action taken for the AE will be handled as "dose 
increased"(the dose cannot be escalated at the subject's discretion)
Dose Interrupted
A temporary discontinuation (suspension) of study drug as action taken for the AE
followed by the resumption of dosing on a later date (including when subjects 
themselves decide to temporarily discontinue) will be handled as a "dose 
interrupted."
10.1.13 Outcome

Procedures
10.2.1
Collection and Reporting of Adverse Events
10.2.1.1
Collection Period of Pretreatment Events and Adverse Events
Pretreatment events will be recorded continuously from when informed consent is 
obtained until the first dose of study drug (Day 1). If it is decided that a subject should be 
withdrawn before the first dose of study drug, PTEs will be recorded until that point in 
time.
AEs will be recorded continuously from the start of study drug administration to subjects 
(Day 1) until the safety follow-up.
10.2.1.2
Reporting of Adverse Events
Investigators will check for subjective symptoms whenever subjects visit. Investigators 
will ask subjects about AEs that may have occurred since the last visit by asking 
questions such as "How have you been since the last visit?"
Any subjects who experience a PTE that meets the criteria for seriousness will be 
followed up by investigators until symptoms resolve or until medically significant 
laboratory abnormalities return to initial levels after informed consent, or else (in the case 
of a permanent or irreversible PTE) until the observed change can be satisfactorily 
explained. No protocol follow-up will be required for PTEs that do not meet the criteria 
for seriousness, regardless of the causal relationship to study procedure.
Any subjects who experience an AE will be followed up by investigators until symptoms 
resolve or until medically significant laboratory abnormalities return to initial levels after 
informed consent, or else (in the case of a permanent or irreversible AE) until the 
observed change can be satisfactorily explained, regardless of the causal relationship to 
study drug. All AEs will be recorded in the eCRF. The following information will be 
documented for each event: event term, start and stop dates, frequency, severity
(intensity), causal relationship to study drug (related, not related), action taken on study 
drug, outcome, causal relationship to study procedures (and procedure considered the 
cause if causally related), and seriousness.
AEs, and PTEs meeting the criteria for seriousness, will be followed up until the 
AE/PTEs resolve or until investigators determine that no further follow-up is needed.

10.2.1.3
Reporting of Special Interest Adverse Events
When an AE of special interest that occurs during the period for recording AEs is 
determined to be medically significant based on the following criteria, investigators will 
report the event to the sponsor (see attachment for contact information) within 24 hours 
of the onset of the AE of special interest or within 24 hours after learning of the event 
from the subject. The principal investigator will also prepare a report of LFT 
abnormalities (same report form as for SAEs) within 10 business days, and submit it with 
a signature or printed name and personal seal to the contact identified in the 
attachment.The "Liver Function Test Abnormality Reporting Checklist (Appendix I)" will 
be used as reference to assist in the preparation of the report.
The criteria for LFT abnormalities are given below:
• ALT or AST > 3 ULN
If ALT or AST levels are > 3 ULN and total bilirubin levels are > 2 ULN or the PT-
INR is > 1.5, and investigators conclude that the levels cannot be explained by any factor 
other that study drug based on the results of retesting (for procedures, see Section 
10.1.5.1), then they will be handled as serious AEs, and information will be recorded and 
reported by the procedures noted in Section 10.2.2.
AEs of special interest will be recorded as AEs in the eCRF. Related information (such as 
photographs, results of additional diagnostic tests, and records of consultations with 
specialists) will also be submitted to the sponsor.
10.2.2
Collection and Reporting of Serious Adverse Events
SAEs that occur in the period for recording AEs will be reported by the following 
procedures. PTEs meeting the criteria for seriousness noted in Section 10.1.4 will be 
reported by the same procedure as SAEs.
All SAEs that occur from the start of study drug administration in subjects until the safety 
follow-up will be reported by the principal investigator to the sponsor within 24 hours of 
confirming or being notified of the event. The initial report of an SAE and all revised or 
additional information will be recorded in an "SAE Report" to be submitted to the 
sponsor. Copies of related source documentation on medical treatment of subjects will be 
submitted to the sponsor as soon as possible. In cases of death, a copy of the autopsy 
report will be submitted, if possible.
Even after the end of the study, treatment-related SAEs will be reported to the sponsor 
within 24 hours of confirming or being notified of the event.
SAEs leading to withdrawal from the study or discontinuation of study drug will be 
recorded in initial or subsequent "SAE Reports" and in the eCRF.
As a general rule, the initial report of an SAE will be faxed to the Safety Information 
Emergency Response Center using the prescribed "Report of an SAE [Initial Report]" 
form. After faxing the form, the principal investigator will submit the original to the 
monitors.

After the initial report of the SAE, the principal investigator will report detailed 
information to the sponsor within 10 calendar days. As a general rule, the detailed 
information will be faxed to the Safety Information Emergency Response Center using 
the prescribed "Report of SAEs (Detailed Information)" form. After faxing the form, the 
principal investigator will submit the original to the monitors. Any modifications of the 
contents of the report will be similarly reported.

When the Safety Information Emergency Response Center cannot be contacted, the 
information will, as a general rule, be reported to the monitors using the prescribed 
"Report of an SAE [Initial Report]" form or "Report of SAEs (Detailed Information)" 
form.
All SAEs occurring onsite will be reported by the principal investigator to the head of the 
investigational site by the established procedures in force at the investigational site and to 
the sponsor in accordance with this protocol.
The expectedness of SAEs will be determined on the basis of the Investigator's Brochure 
(including information on AEs reported to investigational site).
10.2.3
Reporting of Drug-Induced LFT Abnormalities Potentially Leading to 
Severe Liver Disorders
Investigators will report ALT or AST levels > 3 ULN to the sponsor and will promptly 
investigate detailed subject information and potential causes other than study drug 
(presence or absence of acute viral hepatitis type A or B, or other acute liver diseases, 
medical history, and complications). Retesting will also be performed (see Section 
10.1.5). If ALT or AST levels are > 3 ULN and total bilirubin levels are > 2 ULN 
or the PT-INR is > 1.5, and investigators conclude that the levels cannot be explained by 
any factor other that study drug, the information will be reported by the same procedure 
for SAEs (see Section 10.2.1.3).
10.3
Follow-up of Serious Adverse Events
If information not reported in the detailed report becomes available at a later date, 
investigators will record the information on a copy of the SAE report or will prepare a 
separate document, and one or the other will be submitted to the contact identified in the 
attachment. Investigational site-related data (such as ECG findings, laboratory findings, 
summary of report of discharge from hospital, and results of autopsy) will be submitted 
upon request to the sponsor or the IRB.
Investigators will follow-up all SAEs until they resolve or until the final outcome is 
determined.

reactions (SUSARs) and other SAEs subject to expedited reporting to the regulatory 
authorities, principal investigators, and the IRBs/head of the investigational site in 
accordance with the local regulations of the counties in which the study is being 
conducted. The sponsor or the sponsor's CRO will submit an expedited report of fatal or 
life-threatening SUSARs within 7 days, and of any other serious events within 15 days, 
of first learning of or obtaining additional information on the event to the regulatory 
authorities. The sponsor will also submit an expedited report of other safety issues
potentially having a significant effect on the benefit-risk assessment of study drug, 
continuation of study drug treatment, or continuation of the study. The investigational

DATA HANDLING AND RECORDKEEPING
The full details of procedures for data handling will be documented in the Data 
Management Plan. AEs, PTEs, medical history, and concurrent medical conditions will 
be coded using the Medical Dictionary for Regulatory Activities (MedDRA). Drugs will 
be coded using the World Health Organization (WHO) Drug Dictionary [generic term] 
and the Japanese Drug Dictionary.
12.1
Electronic Case Report Form
Completed eCRFs are required for each subject who signs informed consent.
The sponsor or its designee will supply the investigational site with access to the eCRF 
system. The sponsor will make arrangements to train the investigators and appropriate 
study support staff in use of the eCRF system. The eCRFs will be used to transmit the 
information collected during the study to the sponsor and regulatory authorities. The 
eCRF must be completed in English. Data will be directly recorded onto eCRF.
The following will be recorded as an audit trail when changes or revisions are made in 
the eCRF: the original and changed/revised information, person making the change or 
revision, and the date and reasons for the change or revision.
The principal investigator must review the eCRFs for completeness and accuracy, and 
must electronically sign the appropriate page of the eCRF. The principal investigator 
bears full responsibility for the accuracy and reliability of all data recorded in the eCRFs.
The following data will not be directly recorded in the eCRF.
1)
Tumor marker, BMP concentration, and pharmacodynamic parameters (except for 
SHBG) measured by an external measurement facilities.
2)
Plasma drug concentration results
Investigators will use the eCRF change and revision record (Data Clarification Form) 
provided by the sponsor when changing or revising recorded entries in the eCRF after the 
clinical trial database has been locked. The principal investigator must review the data 
change for accuracy and completeness, and must provide a signature or printed name and 
personal seal, and the date.
The sponsor or its designee will check the accuracy and completeness of the eCRF when 
visiting the investigational site. The sponsor or its designee will be permitted to review 
subject's medical and hospital records related to the study to ensure the accuracy of the 
eCRFs. Completed eCRFs are the property of the sponsor, and should not be made 
available in any form to third parties other than regulatory authorities without the written 
permission of the sponsor.

Statistical and Analytical Plans
Analysts will prepare and finalize the Statistical Analysis Plan before database lock. The 
Statistical Analysis Plan will describe in detail the definitions of the endpoints and 
analytical methods in order to meet all study objectives.
Data review will take place before database lock. The accuracy and completeness of the 
study data, the evaluability of subjects, and the appropriateness of the planned analysis 
will be assessed during data review.
13.1.1
Analysis Sets
Four populations for analysis will be established in this study: the full analysis set, the 
safety analysis set, the DLT analysis set, and the pharmacokinetic analysis set. The safety 
analysis set will be defined as all subjects who receive at least 1 dose of any study drug. 
The DLT analysis set will be defined as all subjects who can be evaluated for DLTs (see 
Section 6.1.2.3). The analysis sets will be defined in detail in the separately prepared 
"Rules for Handling Analytical Data."
Before database lock, the sponsor will consult the medical expert as needed to check on 
the appropriateness of the analysis set definitions and rules for handling the analysis of 
the case data in the sets, and will finalize the "The Rules for Handling Analytical Data" 
after deciding how to handle problematic issues not specified at the planning stage.
13.1.2

QUALITY CONTROL AND QUALITY ASSURANCE
14.1
Monitoring of Investigational Site
Monitoring visits to the investigational site will be made periodically during the study to 
ensure that all aspects of the protocol are followed. Source documents will be reviewed 
for verification of data recorded on the eCRFs. Source documents are defined as original 
documents, data, and records. The investigator and institution guarantee access to source 
documents by the sponsor or its designee and by the IRB.
The sponsor or its designee will access the principal investigator's files, medication, 
medical records of subjects, and records such as the informed consent form to ensure that 
the study is being properly conducted in compliance with the protocol. They will also 
confirm the consistency of the eCRFs with related source documents. Investigators and 
other study support staff members will take the time to accommodate monitors when they 
visit the investigational site for monitoring purposes.
14.2
Protocol Deviations
Investigators may deviate from or modify the protocol without the prior written 
agreement of the sponsor or prior approval of the IRB for medically unavoidable 
circumstances, such as to avoid immediate hazards to subjects. On such occasions, the 
principal investigator will inform the sponsor and head of the investigational site in 
writing of the details of and reasons for the deviation or change, will keep copies of the 
notification, and will reach agreement with the sponsor on protocol revisions as needed.  
If the protocol is to be revised, a draft will be submitted as soon as possible to the head of 
the investigational site, and the approval of the IRB will be required.
Investigators should document all deviations from the protocol.
14.3
Quality Assurance Audits and Regulatory Authority Inspections
The sponsor or designee will audit the investigational site as needed. On such occasions, 
an auditor designated by the sponsor will contact the investigational site beforehand to 
schedule the auditing visit. The auditor may ask to visit the facilities where laboratory 
test samples are kept, the facilities where medication is stored and prepared, and other 
facilities used during the study. During this study, inspections may also be carried out by 
regulatory authorities, including overseas agencies (such as the US Food and Drug 
Administration [FDA] and the UK Medicines and Healthcare Products Regulatory 
Agency [MHRA]).  The sponsor will be notified immediately whenever the 
investigational site receives a request for an inspection by the regulatory authorities.  The 
principal investigator and head of the investigational site will ensure that the auditor has 
access to all study-related documentation set forth in Section 14.1.

ETHICAL ASPECTS OF THE STUDY
This trial will be conducted with the highest respect for the individual participants (ie, 
subjects) according to the protocol, the ethical principles that have their origin in the 
Declaration of Helsinki, and International Conference on Harmonisation (ICH) 
Guidelines for GCP. Investigators will conduct the study in accordance with regional 
regulatory requirements and the "Responsibilities of the Principal Investigator" in
Appendix F.
15.1
IRB Approval
The IRB must be will be constituted according to the applicable local regulations in 
regions participating in the study. The sponsor or designee will obtain documentation of 
the names and affiliations of the IRB members. When IRB members directly participate 
in the study, documentation that they are not involved in the review and decision-making 
process must be obtained.
The sponsor or designee will submit related documents to the IRB for review and 
approval of the protocol. In addition to the study protocol, Investigator's Brochure and 
copies of the informed consent as well as materials and advertising related to the 
recruitment of subjects, if needed, and other documents required by local regulations 
must also be submitted to central or local IRBs for approval. The sponsor or designee 
will obtain documented approval of the protocol and informed consent form by the IRB 
before the start of the study (i.e., before shipment of the sponsor-supplied drug or study 
specific screening activity). The IRB or IEC approval must refer to the study by exact 
protocol title, number, and version date; identify versions of other documents (eg, 
informed consent form) reviewed; and state the approval date. The sponsor will ship drug
after confirming the appropriateness of the documented regulations of the investigational 
site. Until the site receives drug, no protocol activities, including screening may occur.
The investigational site will follow all requirements specified by the IRB. This includes 
notifications to the IRB regarding protocol amendments, updates to the informed consent 
form, revisions of materials related to subject recruitment, reports on safety required by 
local regulatory requirements, periodic reports on the conduct of the study as stipulated 
by the IRB, and the study completion report. The sponsor or designee will obtain all 
documented IRB approval of the above and related materials.
Financial compensation paid to subjects should be kept to a level that will not provide 
undue incentive to participate in the study. Financial relief must be approved by the IRB 
and sponsor.
PGx analysis of collected and stored samples will perform at the time when the details 
have been decided. At that time, the sponsor will prepare a PGx protocol, and the
protocol will require prior approval of the sponsor.
15.2
Patient Information, Informed Consent, and Subject Authorization
Written consent documents will embody the elements of informed consent as described in 
the Declaration of Helsinki and the ICH Guidelines for GCP and will be in accordance 
with all applicable laws and regulations. The informed consent form will describe the

planned and permitted use (either in Japan or abroad: submission to third parties) and 
disclosure of the personal information and personal medical information of subjects in 
this study. The informed consent form will further explain the nature of the study, 
objectives, and of the potential risks and benefits. The informed consent form will also 
detail the requirements of the participant and the fact that he or she is free to withdraw at 
any time without giving a reason and without prejudice to his or her further medical care.
The principal investigator is responsible for the preparation and contents of the informed 
consent form, and for obtaining the approval of the IRB. The informed consent form 
must be approved by the IRB before being used.
The informed consent form must be written in a language fully comprehensible to the 
prospective subject. Investigators will be responsible for providing subjects with a 
detailed explanation of the contents of the informed consent form. Information should be 
provided verbally and in writing by a method deemed suitable by the IRB whenever 
possible.
Investigators will give subjects (1) a chance to ask questions about the study and 
(2) enough time to decide whether to participate in the study. Subjects who decide to 
participate in the study will personally sign and date the informed consent form before 
participating in the study. Investigators will ask subjects to use a black or blue ball point 
pen to sign the form using their full legal names. Investigators will also sign and date the 
informed consent form before the subject can participate in the study.
Investigators will keep the signed original informed consent form. The date on which 
subjects sign the informed consent form will be recorded by investigators in the medical 
records of the subjects. Subjects will be given a copy of the signed informed consent 
form.
If the informed consent form is revised, investigators will again obtain the informed 
consent of the subjects using the same procedures that were used to obtain initial consent. 
The date on which informed consent is again obtained will be recorded in the medical 
records of the subjects, and subjects will be given a copy of the revised informed consent 
form.
Subjects who have received an explanation of the study based on the informed consent 
form will be given an explanation of PGx analysis based on the "Informed Consent Form 
for PGx Analysis in the TAK-385 Study." Specimens for PGx analysis will be obtained 
from subjects who sign both the informed consent for the study and the informed consent 
for PGx analysis.
The procedure in Section 9.4 will be followed whenever subjects would prefer their 
stored samples to be disposed of.
15.3
Subject Confidentiality
The sponsor or designee affirm and uphold the principle of the subject’s right to 
protection against invasion of privacy. Throughout this study, a subject’s source data will 
only be linked to the sponsor’s clinical study database or documentation via a unique 
subject identification number. As permitted by all applicable laws and regulations, limited 


TAK-385 
TB-AK160108

CONFIDENTIAL
subject attributes, such as sex, age, or date of birth, and subject initials may be used to 
verify the subject and accuracy of the subject identification number.
To comply with ICH Guidelines for GCP and to verify compliance with this protocol, the 
sponsor requires the investigator to permit its monitor or designee’s monitor, 
representatives from any regulatory authority (such as the FDA, MHRA, and PMDA), the 
sponsor’s designated auditors, and the appropriate IRBs and IECs to review the subject’s 
original medical records (source data or documents), including, but not limited to, 
laboratory test result reports, ECG reports, admission and discharge summaries for 
hospital admissions occurring during a subject’s study participation, and autopsy reports. 
Access to a subject’s original medical records requires the specific authorization of the 
subject as part of the informed consent process (see Section 15.2).
Copies of any subject source documents that are provided to the sponsor must have 
certain personally identifiable information removed (ie, the subject's name, address, and 
other identifier fields not collected on the subject's eCRF).
15.4
Publication, Disclosure, and Clinical Trial Registration Policy
15.4.1
Publication and Disclosure
The principal investigator is obliged to provide the sponsor with complete test results and 
all data derived by the investigator from the study. During the study, except when 
required by laws or regulations, only the sponsor may disclose study information to other 
investigators or regulatory authorities. Except where otherwise permitted by the Clinical 
Study Agreement, any public disclosure of the protocol and study results (including 
public websites) is the responsibility of the sponsor.
The sponsor may publish any data or information obtained from the study (including data 
and information provided by the principal investigator) without the consent of the 
principal investigator.
Investigators need to obtain the prior written permission of the sponsor to publish any 
information obtained from the study, such as to a professional associations.
15.4.2
Clinical Trial Registration
In order to ensure that information on clinical trials reaches the public in a timely manner 
and to comply with applicable laws, regulations and guidance, Takeda will, at a minimum 
register interventional clinical trials it sponsors anywhere in the world on a public 
website (JAPIC-CTI) before the start of the clinical trial. The sponsor's contact 
information will be registered for general access along with the city, state (in the USA), 
and country where the trial is being conducted as well as subject recruitment status.
For some registries, Takeda will assist callers in locating trial sites closest to their homes 
by providing the investigator name, address, and phone number to the callers requesting 
trial information. Once subjects receive investigator contact information, they may call 
the site requesting enrollment into the trial. The investigative sites are encouraged to 
handle the trial inquiries according to their established subject screening process. If the 


TAK-385 
TB-AK160108

Amendment 1
23 January 2015
CONFIDENTIAL
caller asks additional questions beyond the topic of trial enrollment, they should be 
referred to the sponsor.
Any investigator who objects to Takeda providing this information to callers must 
provide Takeda with a written notice requesting that their information not be listed on the 
registry site.
15.4.3
Clinical Trial Results Disclosure
Takeda will post the results of clinical trials on a public website (JAPIC-CTI), as required 
by applicable laws and/or regulations, regardless of the results.
15.5
Insurance and Compensation for Injury
Each subject in the study must be insured in accordance with the regulations applicable to 
the site where the subject is participating. If a local underwriter is required, then the 
sponsor or its designee will obtain clinical study insurance against the risk of injury to 
clinical study subjects.
Refer to the Clinical Study Agreement regarding the sponsor’s policy on subject 
compensation and treatment for injury. If the investigator has questions regarding this 
policy, he or she should contact the sponsor or its designee.

Part A: The dose of TAK-385 will not be increased even if inadequate testosterone 
suppression occurs (< 50 ng/dL). If after treatment initiation the serum testosterone level 
does not drop below 50 ng/dL at 2 or more time points separated by at least 7 days and 
the investigator determines that the patient needs to be switched to some other treatment, 
then TAK-385 treatment will be stopped and the patient withdrawn from the study.
Part B: If the following conditions are met, the dose may be adjusted, taking efficacy and 
safety into consideration. Dose adjustment will be performed when the subject is 
examined by the investigator.

Glossary 
• 
Treatment-emergent adverse event (TEAE): An adverse event whose date of onset occurs on or 
after the start of study drug 
• 
Descriptive statistics: number of subjects, mean, standard deviation (SD), maximum (max), 
minimum (min), and quartiles 
• 
CV: coefficient of variation 
• 
Randomized set: All subjects who were randomized. The first maintenance dose prescribed will 
be used as the treatment group when conducting analyses. 
• 
Treatment group: For part A, the assigned cohort will be the treatment group. For part B, the 
first maintenance dose prescribed will be the treatment group. 
• 
PK: pharmacokinetic 
• 
MAV: markedly abnormal value 
• 
ATC: anatomical therapeutic chemical 
• 
LDH: lactic dehydrogenase 
• 
GGT: gamma-glutamyl transpeptidase 
• 
CK (CPK): creatine phosphokinase/kinase 
• 
Study Day: The day before the first dose of the study drug will be defined as Study Day -1 and 
the day of the first dose will be defined as Study Day 1. If the date of the observation is on the 
same date or after the day of the first dose, Study Day will be calculated relative to Study Day 1. 
Otherwise, Study Day will be calculated relative to Study Day -1. 
• 
Follow-up Day: The day after the last dose of the study drug will be defined as Follow-up Day 
1. Follow-up Day will be calculated relative to Day 1. 


Protocol No. TAK-385/TB-AK160108

Definition of Visit Window 
When calculating Study Day relative to a reference date (i.e., date of first dose of study drug [Day 
1]), if the date of the observation is on the same date or after the reference date, it will be calculated 
as: date of observation - reference date + 1; otherwise, it will be calculated as: date of observation - 
reference date. Hence, reference day is always Day 1 and there is no Day 0. When calculating Study 
Time relative to a reference time (i.e., time of each dose of study drug), it will be calculated as: time 
of observation - reference time. 
When calculating Follow-up Day relative to a reference date (i.e., date of last dose of study drug 
[Follow-up Day 0]), it will be calculated as: date of observation - reference date. Hence, reference 
day is always Follow-up Day 0.  
 
All evaluable data (i.e., non-missing and acceptable according to the Handling Rules for Analysis 
Data) will be handled according to the following rules. 
 
For each visit, observation obtained in the corresponding time interval will be used. If more than one 
observation lies within the same visit window, the observation with the closest Study Day/Study 
Time to the scheduled Study Day/Study Time will be used. If there are two observations equidistant 
to the scheduled Study Day/Study Time, the later observation will be used. This does not apply to 
the end of study visit. For the end of study visit, the last observation obtained in the corresponding 
time interval will be used.

AMS subscale scores and total scores will be calculated as follows. If one or more of the scores 
required for the calculation of a subscale are missing, then that particular subscale and the total score 
will be treated as missing. 
・ Psychological subscale: sum of severity points from questions 6, 7, 8, 11, 13 
・ Somatic subscale: sum of severity points from questions 1, 2, 3, 4, 5, 9, 10 
・ Sexual subscale: sum of severity points from questions 12, 14, 15, 16, 17 
・ Total score: sum of severity points from all questions from 1 to 17

EORTC QLQ-C30 
The Global health status/QoL score and each Functional scales score (physical, role, emotional, 
cognitive, social) will be calculated as follows. The "range" used in the calculations is the difference 
between the maximum possible values of the score and the minimum possible value. If more than 
half of the scores are missing, then the Global health status/QoL score or the Functional scales score 
will be treated as missing. If at least half of the scores are available, then the scores that are available 
will be used for the calculation. 
・ Global health status/QoL score: {[(average of item 29 & 30)-1]/range}*100 
・ Physical functioning: {1-[(average of item 1 to 5)-1]/range}*100 
・ Role functioning: {1-[(average of item 6 & 7)-1]/range}*100 
・ Emotional functioning: {1-[(average of item 21 to 24)-1]/range}*100 
・ Cognitive functioning: {1-[(average of item 20 & 25)-1]/range}*100 
・ Social functioning: {1-[(average of item 26 & 27)-1]/range}*100
