Phase: 1
Protocol Title: A Phase 1 Study to Assess Absolute Bioavailability of TAK-906 and to Characterize Mass Balance, 
Pharmacokinetics, Metabolism, and Excretion of [14C]-TAK-906 in Healthy Male Subjects
Trial Design:
This is an open-label, 2-period, single-dose study in 6 male healthy subjects. 
On Day 1 of Period 1 (absolute bioavailability [ABA] Study Period), after at least a 10-hour fast, 6 subjects will 
receive a single unlabeled oral 50 mg dose of TAK-906 as capsules. At approximately 45 minutes post oral dosing 
(0.75 hour) (ie, 15 minutes prior to the median tmax for the oral unlabeled dose [~ 1.1 hours]), subjects will receive a 
15-minute intravenous (IV) infusion of a microtracer dose of 100 µg (approximately equivalent to 1 microcurie 
~[1 µCi]) [14C]-TAK-906. Serial blood sampling will be performed to determine the pharmacokinetics (PK) of 
TAK-906 and its metabolite (M23) in the plasma for the oral dose and total radioactivity (TRA) and PK of 
[14C]-TAK-906 in the plasma for the IV dose. Urine and fecal output will also be collected up to the morning of Day 5 
(ie, Hour 96) to determine TRA levels and until a discharge criterion is met (ie, 80% or greater of the total dose of 
radioactivity administered is recovered in urine and fecal samples or the excretion of radioactivity in the urine and 
feces combined has declined to ≤1% of the total administered radioactivity per 24-hour interval for at least 2 
consecutive intervals where both a urine and fecal sample are collected) but no less than Day 5 for [14C]-TRA 
excretion in urine and feces. 
In Period 1, subjects will be confined in the clinical research unit (CRU) for at least 5 days (until after the last PK 
sample and morning urine and fecal sample [when passed] are collected) and until discharge criterion is met or up to 
Day 7. Subjects will return to the clinic on Day -1 of Period 2 for Check-in procedures. There will be a washout period 
of at least 7 days between the dose in Period 1 and the dose in Period 2. As per site preference, subjects may be 
confined throughout the washout period. 
On Day 1 of Period 2 (absorption, distribution, metabolism, and elimination [ADME] Study Period), after at least a 
10-hour fast, the subjects will receive a single dose of 50 mg (~100 μCi) [14C]-TAK-906 as an oral solution. Serial 
blood sampling and urine and feces output will be collected. PK of TAK-906 and its metabolite, M23, will be 
determined in plasma and urine; plasma, whole blood, urine, and feces will be collected for TRA determination; and 
plasma, urine, and feces will be collected to characterize the metabolite profiles of TAK-906. Complete urinary and 
fecal output will be collected until at least the morning of Day 6 (ie, Hour 120). Subjects will be confined in the clinic 
until at least this time and until a discharge criterion is met (ie, 90% or greater of the total dose of radioactivity 
administered is recovered in urine and fecal samples or the excretion of radioactivity in the urine and feces combined 
has declined to ≤1% of the total administered radioactivity per 24 hour interval for at least 2 consecutive intervals 
where both a urine and fecal sample are collected) or up to 14 days postdose (ie, Day 15). After Day 15, if subjects 
have not met the discharge criteria, the subject may need to return to  the CRU to collect urine and fecal samples in two 
blocks of 24-hour periods on Days 20, 21, or 22 and Days 27, 28, or 29 based on the discretion of the Sponsor. Release 
of subjects who do not meet a discharge criterion by Day 15 in Period 2 will be reviewed on a case-by-case basis. In 
each of the 2 consecutive intervals, both urine and fecal samples have to be collected and counted for TRA, ie, if only 
urine or feces is collected in a day, this day is not considered to be one of the 2 consecutive intervals. Since up to an 
approximate 24-hour time lag is anticipated for radioactivity counting of samples, actual subject release from the CRU 
may occur 1 day after discharge criteria are met.
In both Periods 1 and 2, any subject who experiences emesis within 3 hours post oral dose will be excluded in the final 
data analysis and will be replaced with a new subject. If a subject experiences emesis after dosing in Period 2, vomitus

will need to be collected as much as possible and assayed for TRA. For a subject who drops out in Period 2, the 
replacement subject will be required to complete Period 2 only.
The clinic will contact all subjects (including subjects who terminate the study early) via phone call 30 ± 2 days after 
the last study drug administration to determine if any adverse events (AEs) have occurred since the last study visit. The 
subjects may be requested to return the site for further safety assessment, due to reported AEs, at the Investigator's 
discretion.

.
The safety endpoint will be assessed through 
evaluation of the following:

AE reporting, laboratory tests, ECGs, and vital 
sign parameters after administration of a single 
oral dose (capsule) of TAK-906 followed by 
single IV microtracer dose administration of 
[14C]-TAK-906.
for TAK-906 only: Vz/F and CL/F.

PK parameters for plasma and whole blood 
TRA: Cmax, Tmax, time-matched AUCt (where t is 
the last common time point at which TRA and 
plasma TAK-906 are quantifiable in all 
subjects), AUC
, AUC , and t
The safety endpoint will be assessed through 
evaluation of the following:

AE reporting, laboratory tests, ECGs, and vital 
sign parameters after a single oral dose 
(solution) of [14C]-TAK-906.
Statistical Considerations:
Descriptive statistics will be provided for the TRA (whole blood [Period 2], plasma, urine, feces [Periods 1 and 2], and 
if applicable, emesis [Period 2]), TAK-906 and metabolite concentrations and PK parameters (plasma and urine 
[Period 2]), and [14C]-TAK-906 concentrations (plasma, urine, feces [Period 1]), and the metabolite profile of 
TAK-906 (plasma, urine, feces [Period 2]), using appropriate summary statistics to be fully specified in the SAP.
ABA of TAK-906 (Period 1) will be estimated using a ninety percent (90%) confidence interval (CI) constructed for 
the difference in least-squares (LS) mean on the log scale for dose normalized AUC∞ between a single oral and the IV 
microtracer dose. Exponentiating the log-scale 90% CI will provide a 90% CI for the dose normalized AUC∞
geometric mean ratio (GMR); TAK-906 administered as oral dose / [14C]-TAK-906 administered as IV microtracer 
dose. AUClast will be analyzed in a similar fashion if AUC∞ cannot be calculated.
Mass balance will be calculated as a sum of the percent of the TRA recovered in urine and feces relative to the 
administered radioactivity dose minus any radioactivity lost due to emesis (if any occurred).
Sample Size Justification: The sample size of 6 male healthy subjects was selected empirically without statistical 
considerations and is deemed adequate to meet the study objectives. In addition, this sample size is limited based on 
clinical considerations for this type of study and in order to limit exposure to radioactivity.

Period 1.
d Subjects will be admitted to the CRU on Day -1, at the time indicated by the CRU. If the CRU decides to confine the subjects throughout the washout period, some 
safety events at check-in (eg, clinical laboratory tests, urine drug and alcohol screen, cotinine test, vital signs, and ECGs) may not be performed, following a 
decision by Investigator.
e Subjects who do not meet a discharge criterion in Period 1 (ie, 80% or greater of the total dose of radioactivity administered is recovered in urine and fecal samples 
or the excretion of radioactivity in the urine and feces combined has declined to ≤1% of the total administered radioactivity per 24-hour interval for at least 
2 consecutive intervals where both a urine and fecal sample are collected) by Day 5, will remain confined and undergo study procedures until a discharge criterion 
is met or up to Day 7.
f A full physical examination will be conducted at screening. Abbreviated physical examinations are to be conducted on Day -1 of each period. These examinations 
will be repeated at the discharge day in Period 2 (ie, Day 15 or earlier). If the subject is required to return to the clinic facility to collect urine and fecal samples in 
two blocks of 24 hour periods on Days 20, 21, or 22 and Days 27, 28, or 29 at the discretion of the Sponsor, those exams will be repeated at the applicable block 
discharge day. Symptom-driven physical examination may be performed at additional times, at the Investigator’s or designee’s discretion. Release of subjects who 
do not meet a discharge criterion by Day 15 in Period 2 will be reviewed on a case-by-case basis.
g 12-Lead ECG and Vital signs (ie, pulse rate and blood pressure) are to be assessed within 24 hours prior to Day 1 oral dosing and at 1- and 4-hour post oral drug 
administration on Day 1; Vital signs (ie, respiratory rate and temperature) are to be assessed within 24 hours prior to Day 1 oral dosing, and at 4-hour post oral drug 
administration on Day 1. All ECG and vital sign assessments will be performed after the subjects have rested for at least 5 minutes.
h Samples for serum chemistry will be obtained following a fast of at least 8 hours, however, in case of dropouts or rechecks, subjects may not have fasted for 
8 hours prior to the serum chemistry sample being taken. Coagulation tests (prothrombin/international normalized ratio) will be performed if subjects have on-study 
aspartate aminotransferase or alanine aminotransferase elevated ≥3x the upper limit of normal.
i Oral drug administration will be performed at Hour 0 of Day 1.
j A 15 minute IV drug administration will begin at approximately 45 minutes post oral dose (Hour 0.75) on Day 1 of Period 1.
k For a detailed blood sampling schedule refer to Table 3.a.
l For a detailed urine and fecal sampling schedule refer to Table 3.b.
m As per site preference, subjects may be confined throughout the washout period. If subjects are confined throughout the washout period, some safety events at 
check-in of Period 2 (eg, clinical laboratory tests, urine drug and alcohol screen, cotinine test, vital signs, and ECGs) may not be performed, following a decision by 
the Investigator.
n The clinic will contact via phone call all subjects (including subjects who terminate the study early) 30 ±2 days after the last study drug administration to determine 
if any AEs have occurred since the last study visit. The subjects may be requested to return the site for further safety assessment, due to reported AEs, at the 
Investigator's discretion.
o To be performed at the end of Period 1 or Period 2 (prior to discharge) or prior to early termination from the study.
p For a detailed blood sampling schedule refer to Table 3.c.
q For a detailed urine and fecal sampling schedule refer to Table 3.d.

INTRODUCTION
4.1
Background
The intended indication for TAK-906 is to treat patients with gastroparesis, a disorder of the 
stomach characterized by delayed gastric emptying in the absence of mechanical obstruction. 
Symptoms are chronic and include nausea, vomiting, early satiety, abdominal pain, and 
postprandial fullness with episodic exacerbation [1]. The prevalence of gastroparesis in the United 
States (US) is estimated to be approximately 24.2 per 100,000 [2]. In cases of chronic 
gastroparesis, diabetic (29%), postsurgical (13%), and idiopathic (36%) etiologies comprise the 
majority of cases in the tertiary referral setting [3]. 
TAK-906 is a peripherally selective (eg, limited penetration of the blood brain barrier [BBB]) 
dopamine D2/D3 receptor antagonist. It has demonstrated suitable PK and pharmacodynamic (PD) 
activity in a phase 1 study and other completed studies. Therefore TAK-906 is expected to reduce 
nausea and vomiting, without the side effects which restrict the use of other D2/D3 antagonists. 
Because of its low BBB penetration and a weak human Ether-a-go-go-Related Gene channel 
affinity indicative of a low potential cardiac risk, TAK-906 is anticipated to have an improved 
safety profile, compared to other D2/D3 antagonists (eg, metoclopramide and domperidone).
To date, at least 259 subjects have been dosed in the completed and ongoing clinical studies in the 
TAK-906 program, of which approximately 149 subjects have received at least 1 dose of active 
treatment with TAK-906. The results from these clinical studies indicate that TAK-906 was well 
tolerated with no significant safety issues attributed to TAK-906 in healthy subjects, patients with 
diabetic gastroparesis, or with idiopathic gastroparesis.
To date, 5 clinical studies have been completed: a phase 1 randomized, double-blind, 
placebo-controlled, single ascending dose (SAD) and multiple ascending dose (MAD) study to 
evaluate the safety, PK, PD, effect of food, and optimal oral dose of TAK-906M in healthy 
subjects (Study AT-01C), a phase 1 itraconazole-interaction study in healthy subjects 
(Study TAK-906-1003), a phase 1 SAD and MAD study in Japanese healthy male subjects in 
Japan (Study TAK-906-1004), a phase 1 drug-drug interaction study with esomeprazole 
(Study TAK-906-1006), and a phase 2 randomized, double-blind and open-label, placebo- and 
active-comparator controlled study to evaluate the safety, PK, and PD of TAK-906 in subjects 
with diabetes mellitus and gastroparesis or idiopathic gastroparesis (TAK-906-1002).
Preclinical Pharmacokinetics
Following oral administration of [14C]-TAK-906M at 3.66 mg/kg (3 mg/kg as TAK-906) to fasted 
male rats and dogs, the t1/2z values of TRA were 1.6 and 6.1 hours, respectively. TAK-906 
radioactivity was almost completely eliminated from circulation by 24 and 120 hours in rats and 
dogs, respectively. Excretion of radioactivity in male rats was almost complete by 48 hours, with 
6.0% and 94.7% of the dosed radioactivity excreted in urine and feces, respectively, and 0.0% 
excreted in expired air. In bile duct-cannulated rats, 86.0%, 5.1%, and 11.0% of the dosed 
radioactivity were excreted into bile, urine, and feces, respectively, by 24 hours. Thus, biliary 
excretion represented the major excretion route for TAK-906 and related substances in rats.

Similarly, in fasted male dogs, urinary and fecal excretion of TAK-906 were 8.0% and 91.3%, 
respectively, over 96 hours.
TAK-906 is a substrate of P-glycoprotein and organic anion transporting polypeptide (OATP) 1B1 
and OATP1B3. Further uptake and kinetic studies using OATP1B1/1B3-expressing cells and 
human hepatocytes as a reference of pravastatin suggested that almost all the in vivo TAK-906 
uptake into human hepatocytes is by a saturable process of transporters, not by a passive process 
and TAK-906 is taken up into the human hepatocytes predominantly by OATP1B1. 
The in vitro metabolism showed that TAK-906 was mainly metabolized by cytochrome P450 
(CYP)3A4/5 and CYP2C8. M23 (pharmacologically inactive) was the metabolite formed by 
human liver cytosol, but not formed by CYP-expressing microsomes. The relative contribution 
ratio of CYP and non-CYP toward in vitro metabolism of TAK-906 using human hepatic S9 with 
or without typical CYP inhibitor was 43.3% and 56.7%, respectively.
Clinical Pharmacokinetics
In Study AT-01C, TAK-906M was administered as a single oral dose (ranging from 5 to 300 mg)
and repeated oral doses (ranging from 50 to 100 mg twice daily) for 5 days to healthy male and 
female non-Japanese subjects. Additionally, the effect of food on the PK of TAK-906 was 
evaluated at a single dose level of 25 mg TAK-906M in this study. TAK-906 showed rapid 
absorption and rapid elimination following oral administration. Median Tmax was ~1.1 hours 
postdose. The half-life (mean) following a single oral dose was ~4 hours when administered in the 
fasted state. Following administration of single oral doses of TAK-906 maleate between 5 and 
300 mg, exposure to TAK-906 increased in a manner generally proportional to dose increment. 
Food had a significant impact on reducing the exposure to TAK-906 in healthy subjects. The ratio 
of geometric LS means for Cmax was 58.06% (90% CI: 38.97% to 86.51%) for the test (fed) to 
reference (fasting) doses. For AUC∞and AUC12, the ratios were 58.23% (90% CI: 45.08% to 
75.21%) and 53.69% (90% CI: 42.79% to 67.37%), respectively. Confidence interval testing 
showed that all parameters were below and generally outside the comparison interval of 80% to 
125%. 
Drug-drug interaction potential of TAK-906 was evaluated. Coadministration of itraconazole, 200 
mg for 5 days, with TAK-906 maleate increased TAK-906 mean Cmax by approximately 2.0-fold 
and AUC∞by approximately 1.3-fold. TAK-906 is not classified as a sensitive CYP3A4 substrate. 
Following coadministration of esomeprazole (40 mg oral capsule) and TAK-906 (25 mg oral 
capsule) to healthy subjects, the AUClast, AUC∞, and Cmax of TAK-906 decreased approximately 
12 to 13% compared to TAK-906 administration alone. The AUClast and AUC∞ of M23 were 
similar, but the Cmax of M23 increased by approximately 20% when TAK-906 was coadministered 
with esomeprazole compared to TAK-906 administration alone.
Refer to the TAK-906 Investigator’s Brochure for complete information on the investigational 
product [4].

4.2
Rationale for the Proposed Study
The primary purposes of the present study are to characterize the ABA (Period 1) and the 
absorption, distribution, metabolism, excretion, and mass balance of TAK-906 after single oral 
administration (Period 2) in healthy adult male subjects, by collecting plasma and urine samples 
for TAK-906 and M23 analysis, plasma, urine, whole blood, and fecal samples for TRA analysis 
and, plasma, urine, and fecal samples for metabolite profiling. The study will provide data required 
to evaluate the ABA, mass balance, and the metabolite profile of TAK-906 in humans. 
4.3
Benefit/Risk Profile
The single dose of 50 mg TAK-906 is selected for this study and has been demonstrated to be safe 
and well tolerated in healthy subjects in studies conducted to date (IB, 2018).
The estimated radiation dose from a single IV administration of [14C]-TAK-906 (~1 µCi) and a 
single oral dose of [14C]-TAK-906 (~100 μCi) is below the radiation dose limits set forth in 
21 CFR 361 for the whole body, active blood forming organs, lens of the eye, gonads, and other 
organs (see Section 6.3.2). Thus, the health risk resulting from exposure to radiation in the study 
drug is very low.
The inclusion and exclusion criteria, screening, and safety monitoring practices employed by this 
protocol (ie, 12-lead ECG, vital signs, clinical laboratory tests, AE questioning, and physical 
examination) are adequate to protect the subjects’ safety and should detect all TEAEs.
There will be no direct health benefit for study participants from receipt of study drug. An indirect 
health benefit to the healthy subjects enrolled in this study is the free medical tests received at 
screening and during the study.

TRIAL DESIGN AND DESCRIPTION
6.1
Trial Design 
This is an open-label, 2-period, single-dose study in 6 male healthy subjects. 
On Day 1 of Period 1 (ABA Study Period), after at least a 10-hour fast, 6 subjects will receive a 
single unlabeled oral 50 mg dose of TAK-906 as capsules. At approximately 45 minutes post oral 
dosing (0.75 hour) (ie, 15 minutes prior to the median tmax for the oral unlabeled dose 
[~ 1.1 hours]), subjects will receive a 15-minute IV infusion of a microtracer dose of 100 µg 
(approximately equivalent to 1 µCi ~[1 µCi]) [14C]-TAK-906. Serial blood sampling will be 
performed to determine the PK of TAK-906 and its metabolite (M23) in the plasma for the oral 
dose and TRA and PK of [14C]-TAK-906 in the plasma for the IV dose. Urine and fecal output will 
also be collected up to the morning of Day 5 (ie, Hour 96) to determine TRA levels and 
[14C]-TAK-906 PK and until a discharge criterion is met (ie, 80% or greater of the total dose of 
radioactivity administered is recovered in urine and fecal samples or the excretion of radioactivity 
in the urine and feces combined has declined to ≤1% of the total administered radioactivity per 
24-hour interval for at least 2 consecutive intervals where both a urine and fecal sample are 
collected) but no less than Day 5 for [14C]-TRA excretion in urine and feces. 
In Period 1, subjects will be confined in the CRU for at least 5 days (until after the last PK sample 
and morning urine and fecal sample [when passed] are collected) and until discharge criterion is 
met or up to Day 7. Subjects will return to the clinic on Day -1 of Period 2 for Check-in procedures. 
There will be a washout period of at least 7 days between the dose in Period 1 and the dose in 
Period 2. As per site preference, subjects may be confined throughout the washout period. 
On Day 1 of Period 2 (ADME Study Period), after at least a 10-hour fast, the subjects will receive 
a single dose of 50 mg (~100 μCi) [14C]-TAK-906 as an oral solution. Serial blood sampling and 
urine and feces output will be collected. PK of TAK-906 and its metabolite, M23, will be 
determined in plasma and urine; plasma, whole blood, urine, and feces will be collected for TRA 
determination; and plasma, urine, and feces will be collected to characterize the metabolite profiles 
of TAK-906. Complete urinary and fecal output will be collected until at least the morning of Day 
6 (ie, Hour 120). Subjects will be confined in the clinic until at least this time and until a discharge 
criterion is met (ie, 90% or greater of the total dose of radioactivity administered is recovered in 
urine and fecal samples or the excretion of radioactivity in the urine and feces combined has 
declined to ≤1% of the total administered radioactivity per 24 hour interval for at least 
2 consecutive intervals where both a urine and fecal sample are collected) or up to 14 days 
postdose (ie, Day 15). After Day 15, if subjects have not met the discharge criteria, the subject may 
need to return to the CRU to collect urine and fecal samples in two blocks of 24-hour periods on 
Days 20, 21, or 22 and Days 27, 28, or 29 based on the discretion of the Sponsor. Release of 
subjects who do not meet a discharge criterion by Day 15 in Period 2 will be reviewed on a 
case-by-case basis. In each of the 2 consecutive intervals, both urine and fecal samples have to be 
collected and counted for TRA, ie, if only urine or feces is collected in a day, this day is not 
considered to be one of the 2 consecutive intervals. Since up to an approximate 24-hour time lag is

anticipated for radioactivity counting of samples, actual subject release from the CRU may occur 
1 day after discharge criteria are met.
In both Periods 1 and 2, any subject who experiences emesis within 3 hours post oral dose will be 
excluded in the final data analysis and will be replaced with a new subject. If a subject experiences 
emesis after dosing in Period 2, vomitus will need to be collected as much as possible and assayed 
for TRA. For a subject who drops out in Period 2, the replacement subject will be required to 
complete Period 2 only. 
The clinic will contact all subjects (including subjects who terminate the study early) via phone 
call, 30 ± 2 days after the last study drug administration to determine if any AEs have occurred 
since the last study visit. The subjects may be requested to return the site for further safety 
assessment, due to reported AEs, at the Investigator's discretion.
The planned dose levels of TAK-906 to be evaluated are outlined in Table 6.a.

Rationale for Trial Design, Dose, and Endpoints
6.3.1
Rationale of Trial Design 
In Period 1 of the study, the ABA of TAK-906 will be estimated using a labeled IV microtracer 
administered at ~0.75 hours ie, approximately 45 min post oral dose (over approximately 
15 minutes) after an unlabeled oral dose in order to characterize the disposition properties of 
TAK-906. In order to determine ABA accurately and reliably, a healthy adult population is chosen.
Characterization of the disposition of a drug following IV administration facilitates the 
understanding of fundamental aspects of TAK-906’s PK that cannot be determined from oral 
dosing alone, including bioavailability, intrinsic clearance, and volume of distribution. The results 
of this trial will contribute to a robust understanding of the PK characteristics of TAK-906.
In Period 2 of the study, characterization of the absorption, distribution, metabolism, excretion, 
and mass balance of TAK-906 after oral administration of a single 50 mg (~100 μCi) 
[14C]-TAK-906 will be achieved by collecting plasma and urine samples for drug concentration 
analysis; plasma, whole blood, urine, and fecal samples for TRA analysis; and plasma, urine, and

and the metabolite profile of TAK-906 in humans.
6.3.2
Rationale for Dose 
A single oral dose of 50 mg of unlabeled and [14C]-TAK-906 will be used in the study in Periods 1 
and 2. This is the highest dose of TAK-906 which is being evaluated in a dose range phase-IIb trial 
in gastroparesis patients. Safety and tolerability of TAK-906 were studied up to a single dose of 
300 mg and 100 mg twice daily for 4 days via the oral route in healthy subjects and found to be safe 
and tolerable. 
Radiolabeled doses [14C] were administered to male Sprague-Dawley and Long-Evans rats (blood 
and pigmented skin only). Tissue concentration versus time profiles showed that 
elimination/tissue release of radioactivity from all tissues was generally very rapid and 
concentrations for many tissues were below the limit of quantitation (BLQ). 
The calculated radiation absorbed doses were relatively low (< 2.000 mrem and < 0.020 mSv) for 
most tissues (except bladder) for male human subjects following a single oral dose of 
[14C]TAK-906 of 100 μCi. The highest estimated absorbed dose was in the bladder, which had a 
value of 4.854 mrem (0.049 mSv) and represented 0.097% of the allowable 5000 mrem United 
States (US)-Food and Drug Administration (FDA) exposure limit for a single tissue. In descending 
order, the next highest radiation absorbed doses (> 0.200 mrem) were in the small intestine 
(1.270 mrem, 0.013 mSv), the liver (0.917 mrem, 0.009 mSv), the mesenteric lymph node (0.221 
mrem, 0.002 mSv), and the kidney (0.219 mrem, 0.002 mSv). Blood, blood-forming organs, and 
lymph nodes each had an estimated dose of ≤0.221 mrem (0.002 mSv), which represented 
0.0074% of the allowable 3000 mrem US-FDA exposure limit. Radioactive concentrations in the 
eyes and testis (gonads) were BLQ at all sampled time-points, which represented 0% of the 
allowable 3000 mrem exposure limit. The overall human male whole-body exposure was 
calculated to be 0.3143 mrem (0.0031 mSv), which represented approximately 0.010% of the 
allowable 3000 mrem US-FDA exposure limit, and 0.31% of the allowable 1 mSv ICRP 
(International Committee on Radiation Protection) limit and is considered to be safe. A single oral 
dose of up to 100 μCi (3.70 MBq) of [14C]-TAK-906 is not expected to represent a major 
whole-body radiation exposure risk to human male subjects as defined in the US-FDA and ICRP 
guidelines.

Critical Procedures Based on Trial Objectives: Timing of Procedures 
For this study, the blood, plasma, urine, and feces collections for total radioactivity, plasma and 
urine concentrations, and plasma, urine, and feces for metabolite profiling for TAK-906 and M23, 
as appropriate, are the critical procedures and are required to be collected, as appropriate, as close 
to the scheduled times defined in this protocol as possible.

PK Measurements 
9.3.1.1
Plasma and Whole Blood PK Measurements
PK parameters for whole blood and plasma radioactivity concentration equivalents (Period 2) and 
for plasma TAK-906 and metabolite concentrations (Periods 1 and 2) following oral 
administration will be calculated as follows, as appropriate and not limited to:
AUClast:
The area under the concentration versus time curve, from time 0 to the last 
observed non-zero concentration, as calculated by the linear trapezoidal 
method.
AUC∞:
The area under the concentration versus time curve, from time 0 
extrapolated to infinity. AUC∞is calculated as AUCt plus the ratio of the last 
measurable blood concentration to the elimination rate constant.
AUCt:
The area under the concentration-time curve from time 0 to time of the last 
common time point “t” at which total radioactivity and TAK-906 are 
quantifiable for all subjects. 
AUC%extrap:
Percent of AUC∞ extrapolated, represented as (1 - AUCt/AUC∞)*100.
CL/F:
Apparent total plasma clearance after oral (extravascular) administration, 
calculated as Dose/AUC0-∞ (parent only)
Cmax:
Maximum observed concentration.
Tmax:
Time to reach Cmax. If the maximum value occurs at more than one time 
point, Tmax is defined as the first time point with this value.
t½:
Apparent first-order terminal elimination half-life will be calculated as 
0.693/Kel.
Vz/F:
Apparent volume of distribution during the terminal elimination phase after 
oral (extravascular) administration, calculated as Dose/(AUC0-∞x Kel) 
(parent only)
Kel:
Kel is the apparent first-order terminal elimination rate constant calculated 
from a semi-log plot of the plasma concentration versus time curve. The 
parameter will be calculated by linear least-squares regression analysis 
using the maximum number of points in the terminal log-linear phase (eg, 
three or more non-zero plasma concentrations).
PK parameters for plasma concentrations of [14C]-TAK-906 and plasma radioactivity 
concentration equivalents following IV infusion (Period 1) will be calculated as follows, as

more non-zero plasma concentrations).
Vss:
Volume of distribution during the terminal disposition phase after 
intravenous administration.
In all above-listed PK parameter calculations, no value for Kel, AUC∞, AUC%extrap, t½, CL/F, Vz/F, 
CL, or Vss will be reported for cases that do not exhibit a terminal log-linear phase in the 
concentration versus time profile and AUClast would be used for the further calculations, wherever 
necessary if AUC∞would not be available. 
No PK parameters will be calculated for subjects with detectable concentrations or radioactivity 
concentration equivalents at 2 or fewer consecutive time points. 
Individual and mean plasma concentration- or radioactivity concentration equivalent-time curves 
(both linear and log-linear) will be included in the final report.
The absolute bioavailability parameters for TAK-906 (Period 1) will be calculated as follows:
F:
Absolute bioavailability, calculated for plasma TAK-906, calculated as:
Dose (IV) x AUC∞(oral) / Dose (oral) x AUC∞ (IV).
%F:
Percent absolute bioavailability, calculated for plasma TAK-906 as 
[Dose (IV) x AUC∞(oral)] / [Dose (oral) x AUC∞(IV)] x 100.
If AUC∞ cannot not be calculated, AUClast will be used for the F determination.

Confinement
In Period 1, subjects will be housed on Day -1, at the time indicated by the CRU until at least after 
the 96-hour blood draw and morning urine and fecal sample [when passed] (Day 5) and/or study 
procedures and if a discharge criterion is met, or up to Day 7. As per site preference, subjects may 
be confined throughout the washout period.
In Period 2, subjects will be housed on Day -1, at the time indicated by the CRU, and confined until 
at least after the 120-hour blood draw and morning urine and fecal sample [when passed] (Day 6) 
and/or study procedures and if a discharge criterion is met, or up to Day 15. 
All urine and fecal collections will be analyzed for radioactivity levels in both periods to determine 
if the discharge criteria are met. In each of the 2 consecutive periods, both urine and fecal samples 
have to be collected and counted for TRA, ie, if only urine or feces is collected in a day, this day is 
not considered to be one of the 2 consecutive intervals. Subjects will be eligible for discharge if 
they meet either of the following discharge criteria on Day 5 (Period 1) or Day 6 (Period 2):

≥80% (following Period 1 dose) and ≥90%* (following Period 2 dose) of the total dose of 
radioactivity administered has been recovered in the urine and feces; or 

There is ≤1% of the total administered radioactivity in each of two consecutive 24-hour 
intervals where both a urine and fecal sample is provided.
*The specified discharge criteria (ie, ≥90%) for Period 2 is implemented to maximize the 
radioactive dose recovered in the ADME period.
Subjects can be released after Day 15 collection of excreta in Period 2. After Day 15, if subjects 
have not met the discharge criteria, the subject may need to return to the clinic facility to collect 
urine and fecal samples in two blocks of 24-hour periods on Days 20, 21, or 22 and Days 27, 28, or 
29 based on the discretion of the Sponsor. Release of subjects who do not meet a discharge 
criterion by Day 15 in Period 2 will be reviewed on a case-by-case basis.
Since up to an approximate 24-hour time lag is anticipated for radioactivity counting of samples, 
actual subject release from the CRU may occur 1 day after discharge criteria are met.
At all times, a subject may be required to remain at the CRU for longer at the discretion of the 
Investigator or designee. 
The clinic will contact all subjects (including subjects who terminate the study early) via phone 
call, 30 ± 2 days after the last study drug administration to determine if any AEs have occurred 
since the last study visit.

ADVERSE EVENTS
10.1
Definitions and Elements of AEs
An AE is defined as any untoward medical occurrence in a clinical investigation subject who has 
signed informed consent to participate in a study; it does not necessarily have to have a causal 
relationship with the 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.
An untoward finding generally may:

Indicate a new diagnosis or unexpected worsening of a preexisting condition. (Intermittent 
events for pre-existing conditions or underlying disease should not be considered AEs.)

Necessitate therapeutic intervention.

Require an invasive diagnostic procedure.

Require discontinuation or a change in dose of study medication or a concomitant medication.

Be considered unfavorable by the Investigator for any reason.
Diagnoses versus 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) or symptom(s) should be recorded 
appropriately as an AE(s).
Laboratory values and ECG findings:

Changes in laboratory values or ECG parameters maybe considered AEs if they are judged to 
be clinically significant (ie, if some action or intervention is required or if the Investigator 
judges the change to be beyond the range of normal physiologic 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.

If abnormal laboratory values or ECG findings are the result of pathology for which there is an 
overall diagnosis (eg, increased creatinine in renal failure), the diagnosis only should be 
reported appropriately as an AE.
Pre-existing conditions:

A pre-existing condition (present at the time of signing of informed consent) is considered a 
concurrent medical history condition and should NOT be recorded as an AE. A baseline 
evaluation (eg, laboratory test, ECG, X-ray, etc) should NOT be recorded as an AE unless 
related to a study procedure. However, if the subject experiences a worsening or complication

of such a concurrent medical history condition, the worsening or complication should be 
recorded appropriately as an AE (worsening or complication occurs after informed consent is 
signed). Investigators should ensure that the event term recorded captures the change in the 
condition (eg, “worsening of…”).

If a subject has a pre-existing episodic condition (eg, asthma, epilepsy), any occurrence of an 
episode should only be captured as an AE if the episodes become more frequent, serious, or 
severe in nature, that is, Investigators should ensure that the AE term recorded captures the 
change from Baseline in the condition (eg, “worsening of…”).

If a subject has a degenerative concurrent condition (eg, cataracts, rheumatoid arthritis), 
worsening of the condition should only be captured as an AE if occurring to a greater extent to 
that which would be expected. Again, Investigators should ensure that the AE term recorded 
captures the change in the condition (eg, “worsening of…”).
Worsening of AEs:

If the subject experiences a worsening or complication of an AE after the first administration of 
study medication or after any change in study medication, the worsening or complication 
should be recorded as a new AE. Investigators should ensure that the AE term recorded 
captures the change in the condition (eg, “worsening of…”).
Changes in severity of AEs:

If the subject experiences a change in the severity of an AE that is not associated with a change 
in study medication, the event should be captured once with the maximum severity recorded.
Preplanned surgeries or procedures:

Preplanned procedures (surgeries or therapies) that were scheduled prior to signing of 
informed consent are not considered AEs. However, if a preplanned procedure is performed 
early (eg, as an emergency) due to a worsening of the pre-existing condition, the worsening of 
the condition should be captured appropriately as 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 AEs but should be documented in the subject’s source documents. 
Complications resulting from an elective surgery should be reported as AEs.
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. It is up to the Investigator or the reporting physician to decide 
whether a dose is to be considered an overdose, in consultation with the Sponsor.

All cases of overdose (with or without associated AEs) will be documented on an Overdose 
page of the (e)CRF, in order to capture this important safety information consistently in the

Section 10.0.

Serious adverse events (SAEs) of overdose should be reported according to the procedure 
outlined in Section 10.2.8.

In the event of drug overdose, the subject should be treated symptomatically.
10.1.1 SAEs
An SAE is defined as any untoward medical occurrence that at any dose:
1. Results in DEATH.
2. Is LIFE THREATENING.

The term “life threatening” refers to an event in which the subject was 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 were more severe.
3. Requires inpatient HOSPITALIZATION or prolongation of existing hospitalization.
4. Results in persistent or significant DISABILITY/INCAPACITY.
5. Is 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).

Moderate:
An adverse event that is usually alleviated with additional specific therapeutic 
intervention. The event interferes with usual activities of daily living, causing 
discomfort but poses no significant or permanent risk of harm to the research 
participant.
Severe:
An adverse event that interrupts usual activities of daily living, or significantly 
affects clinical status, or may require intensive therapeutic intervention.
10.2.2 Assigning Causality of AEs
The relationship of each AE to study medication(s) 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 a causal

relationship is at least a reasonable possibility, ie, the relationship cannot be 
ruled out, although factors other than the drug, such as underlying diseases, 
complications, concomitant drugs and concurrent treatments, 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 concurrent 
treatments.
10.2.3 Start Date 
The start date of the AE is the date that the first signs/symptoms were noted by the subject and/or 
Investigator.
10.2.4 End Date 
The end date of the AE is the date at which the subject recovered, the event resolved but with 
sequelae or the subject died.
10.2.5 Pattern of Adverse Event (Frequency) 
Episodic AEs (eg, headache) or those which occur repeatedly over a period of consecutive days are 
intermittent. All other events are continuous.
10.2.6 Action Taken With Study Treatment

Drug withdrawn – a study medication is stopped due to the particular AE.

Dose not changed – the particular AE did not require stopping a study medication.

Unknown – only to be used if it has not been possible to determine what action has been taken.

Not applicable – a study medication was stopped for a reason other than the particular AE 
eg, the study has been terminated, the subject died, dosing with study medication had not yet 
started or dosing with study medication was already stopped before the onset of the AE.

Drug interrupted – the dose was interrupted due to the particular AE.
10.2.7 Outcome 

Recovered/resolved – subject returned to first assessment status with respect to the AE.

Recovering/resolving – the intensity is lowered by one or more stages: the diagnosis has or 
signs/symptoms have almost disappeared; the abnormal laboratory value improved, but has 
not returned to the normal range or to the baseline value; the subject died from a cause other 
than the particular AE with the condition remaining “recovering/resolving.”

Not recovered/not resolved – there is no change in the diagnosis, signs or symptoms; the 
intensity of the diagnosis, signs/symptoms or laboratory value on the last day of the observed

study period has become worse than when it started; is an irreversible congenital anomaly; the 
subject died from another cause with the particular AE state remaining “Not recovered/not 
resolved.”

Recovered/ Resolved with sequelae – the subject recovered from an acute AE but was left with 
permanent/significant impairment (eg, recovered from a cardiovascular accident but with 
some persisting paresis).

Fatal – an AE that is considered as the cause of death.

Unknown – the course of the AE cannot be followed up due to hospital change or residence 
change at the end of the subject’s participation in the study.
10.2.8 Collection and Reporting of AEs, SAEs, Special Interest AEs, and Abnormal LFTs
10.2.8.1 Collection Period
Collection of AEs (ie, AEs, SAEs, Special Interest AEs, and Abnormal LFTs) will commence at 
the time the subject signs the informed consent. Routine collection of AEs will continue until the 
follow-up phone call on approximately 30 (± 2 days) days after the last dose of investigational 
product. For subjects who discontinue prior to the administration of study medication, AEs will be 
followed until the subject discontinues study participation. 
10.2.8.2 Reporting AEs
At each study visit, the Investigator will assess whether any subjective AEs have occurred. A 
neutral question, such as “How have you been feeling since your last visit?” may be asked. 
Subjects may report AEs occurring at any other time during the study. Subjects experiencing an 
SAE prior to the first exposure to investigational product must be monitored until the symptoms 
subside and any clinically relevant changes in laboratory values have returned to Baseline or there 
is a satisfactory explanation for the change. Nonserious AEs that begin prior to the first exposure 
to investigational product, related or unrelated to the study procedure, need not be followed-up for 
the purposes of the protocol.
All subjects experiencing AEs, whether considered associated with the use of the study medication 
or not, must be monitored until the symptoms subside and any clinically relevant changes in 
laboratory values have returned to Baseline or until there is a satisfactory explanation for the 
changes observed. All AEs will be documented in the AE page of the CRF, whether or not the 
Investigator concludes that the event is related to the drug treatment. The following information 
will be documented for each event:

Event term.

Start and end date and time.

Pattern of AE (frequency).

Severity/Intensity.

10.2.8.3 Reporting SAEs
When an SAE occurs through the AE collection period it should be reported according to the 
procedure outlined below:
A Takeda SAE form must be completed, in English and signed by the Investigator immediately or 
within 24 hours of first onset or notification of the event. The information should be completed as 
fully as possible but contain, at a minimum:

A short description of the event and the reason why the event is categorized as serious.

Subject identification number.

Investigator’s name.

Name of the study medication(s).

Causality assessment.
The SAE form should be transmitted within 24 hours to the attention of the contact listed in 
Section 14.1.1.
Any SAE spontaneously reported to the Investigator following the AE collection period should be 
reported to the Sponsor if considered related to study participation.
Reporting of SAEs that begin before first administration of investigational product will follow the 
same procedure for SAEs occurring on treatment.
SAE Follow-Up
If information is not available at the time of the first report becomes available at a later date, the 
Investigator should complete a follow-up SAE form or provide other written documentation and 
fax it immediately within 24 hours of receipt. Copies of any relevant data from the hospital notes 
(eg, ECGs, laboratory tests, discharge summary, postmortem results) should be sent to the 
addressee, if requested.
All SAEs should be followed up until resolution or permanent outcome of the event. The timelines 
and procedure for follow-up reports are the same as those for the initial report.
10.2.8.4 Reporting Special Interest AEs 
There are no AEs of Special Interest defined for reporting in this study.

10.2.8.5 Reporting of Abnormal LFTs
If a subject is noted to have ALT or AST elevated >3 ×ULN on 2 consecutive occasions, the 
abnormality should be recorded as an AE. In addition, an LFT Increases CRF must be completed 
providing additional information on relevant recent history, risk factors, clinical signs and 
symptoms and results of any additional diagnostic tests performed.
If a subject is noted to have ALT or AST >3 ×ULN, concurrently with total bilirubin >2 ×ULN for 
which an alternative etiology has not been identified, the event should be recorded as an SAE and 
reported as per Section 10.2.8.3. The Investigator must contact the Medical Monitor for discussion 
of the relevant subject details and possible alternative etiologies, such as acute viral hepatitis A or 
B or other acute liver disease. Follow-up laboratory tests as described in Section 9.2.9 must also be 
performed. In addition, an LFT Increases CRF must be completed and transmitted with the Takeda 
SAE form (as per Section 10.2.9). 
10.2.9 Safety Reporting to Investigators, IRBs or IECs, and Regulatory Authorities 
The Sponsor will be responsible for reporting all suspected unexpected serious adverse reactions 
(SUSARs) and any other applicable SAEs to regulatory authorities, Investigators and IRBs or 
IECs, as applicable, in accordance with national regulations in the countries where the study is 
conducted. Relative to the first awareness of the event by/or further provision to the Sponsor or 
Sponsor’s designee, SUSARs will be submitted within 7 days for fatal and life-threatening events 
and 15 days for other serious events, unless otherwise required by national regulations. The 
Sponsor will also prepare an expedited report for other safety issues where these might materially 
alter the current benefit-risk assessment of an investigational medicinal product or that would be 
sufficient to consider changes in the investigational medicinal products administration or in the 
overall conduct of the trial. The investigational site also will forward a copy of all expedited 
reports to his or her IRB or IEC in accordance with national regulations.

STATISTICAL METHODS
11.1
Statistical and Analytical Plans
Detailed methodology for summary and statistical analyses of the data collected in this study will 
be documented in a SAP. The SAP will be prepared by Celerion and agreed upon with the 
Sponsor. This document may modify the plans outlined in the protocol; however, any major 
modifications of the primary endpoints definition and/or its analysis will also be reflected in a 
protocol amendment. Additional statistical analyses other than those described in this section may 
be performed if deemed appropriate. A clinical pharmacology analysis plan will also be generated 
for the study.
11.1.1 Analysis Sets
11.1.1.1 Safety Set
All subjects who received at least one dose of the study drug will be included in the safety 
evaluations.
11.1.1.2 PK Set
Samples from all subjects will be assayed even if the subjects do not complete the study. All 
subjects who comply sufficiently with the protocol and display an evaluable PK profile (eg, 
exposure to treatment, availability of measurements and absence of major protocol violations) will 
be included in the statistical analyses.
11.1.1.3 PD Set
Not applicable
11.1.2 Analysis of Demography and Other Baseline Characteristics
Continuous demographic data (ie, age, weight, height, and BMI) will be listed and summarized 
using appropriate summary statistics. Categorical demographic data (ie, gender, race, and 
ethnicity) will also be listed and tabulated.
11.1.3 PK Analysis
Descriptive statistics will be provided for the TRA (whole blood [Period 2], plasma, urine, feces 
[Periods 1 and 2], and if applicable, emesis [Period 2]), TAK-906 and metabolite concentrations 
and PK parameters (plasma and urine [Period 2]), and [14C]-TAK-906 concentrations (plasma, 
urine, feces [Period 1]), and the metabolite profile of TAK-906 (plasma, urine, feces [Period 2]), 
using appropriate summary statistics to be fully specified in the SAP.
PK parameters for whole blood, plasma, and TRA concentrations will be calculated as described in 
Section 9.3.1.1 and for urine and feces, as described in Sections 9.3.1.2 and 9.3.1.3, respectively. 
Further details would be specified in the Clinical Pharmacology Analysis Plan.

ABA of TAK-906 (Period 1) will be estimated using a ninety percent (90%) CI constructed for the 
difference in LS mean on the log scale for dose normalized AUC∞ between a single oral and the IV 
microtracer dose. Exponentiating the log-scale 90% CI will provide a 90% CI for the dose 
normalized AUC∞GMR; TAK-906 administered as oral dose / [14C]-TAK-906 administered as IV 
microtracer dose. AUClast will be analyzed in a similar fashion if AUC∞ cannot be calculated.
Mass balance will be calculated as a sum of the percent of the TRA recovered in urine and feces 
relative to the administered radioactivity dose minus any radioactivity lost due to emesis (if any 
occurred).
11.1.4 Analysis of Mass Balance
In Period 2, mass balance will be calculated as a sum of the percent of the TRA recovered in urine 
and feces relative to the administered radioactivity dose minus any radioactivity lost due to emesis 
(if any occurred).
11.1.5 Whole Blood to Plasma Partitioning Ratio 
In Period 2, the fraction of [14C]-radioactivity associated with red blood cells and other cellular 
components of whole blood will also be determined by using the concentration of 
[14C]-radioactivity in whole blood and plasma to calculate the whole blood:plasma partitioning 
ratio. 
11.1.6 Metabolite Profiling
In Period 2, TAK-906 metabolite profiling will be performed in plasma, urine, and feces 
containing sufficient amounts of radioactivity. The percent of dose represented by each of the 
metabolites, if any, will be calculated using the radioactivity concentration equivalent data 
combined with the metabolite profiling data. The percentage of each identified metabolite, if any, 
to total radioactivity in the plasma will be estimated based on plasma metabolite profiling data.
11.1.7 PD Analysis 
Not applicable.
11.1.8 Safety Analysis
All safety data will be populated in the individual CRFs. 
Dosing dates and times will be listed by subject.
Quantitative safety data as well as the difference to baseline, when appropriate, will be 
summarized using the appropriate descriptive statistics.
11.1.8.1 AEs

QUALITY CONTROL AND QUALITY ASSURANCE
12.1
Study-Site Monitoring Visits
Monitoring visits to the study 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 CRFs. Source documents are defined as original documents, data, and records. 
The Investigator and study site guarantee access to source documents by the Sponsor or its 
designee (CRO) and by the IRB or IEC.
All aspects of the study and its documentation will be subject to review by the Sponsor or the 
Sponsor’s designee (as long as blinding is not jeopardized), including but not limited to the 
Investigator’s Binder, trial drug, subject medical records, informed consent documentation, and 
review of CRFs and associated source documents. It is important that the Investigator and other 
study personnel are available during the monitoring visits and that sufficient time is devoted to the 
process.
12.2
Protocol Deviations
The Investigator should not deviate from the protocol, except where necessary to eliminate an 
immediate hazard to trial subjects. Should other unexpected circumstances arise that will require 
deviation from protocol-specified procedures, the Investigator should consult with the Sponsor or 
designee (and IRB or IEC, as required) to determine the appropriate course of action. There will be 
no exemptions (a prospectively approved deviation) from the inclusion or exclusion criteria.
Significant deviations include, but are not limited to, those that involve fraud or misconduct, 
increase the health risk to the subject, or confound interpretation of primary study assessment. 
12.3
Quality Assurance Audits and Regulatory Agency Inspections
The study site also may be subject to quality assurance audits by the Sponsor or designees. In this 
circumstance, the Sponsor-designated auditor will contact the site in advance to arrange an 
auditing visit. The auditor may ask to visit the facilities where laboratory samples are collected, 
where the medication is stored and prepared, and any other facility used during the study. In 
addition, there is the possibility that this study may be inspected by regulatory agencies, including 
those of foreign governments (eg, the FDA, the United Kingdom Medicines and Healthcare 
products Regulatory Agency, the Pharmaceuticals and Medical Devices Agency of Japan). If the 
study site is contacted for an inspection by a regulatory body, the Sponsor should be notified 
immediately. The Investigator guarantees access for quality assurance auditors to all study 
documents as described in Section 12.1.

13.0
ETHICAL ASPECTS OF THE STUDY
This study 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 the International Conference on Harmonisation (ICH) Harmonised Tripartite 
Guideline for GCP. Each Investigator will conduct the study according to applicable local or 
regional regulatory requirements and align his or her conduct in accordance with the 
“Responsibilities of the Investigator” that are listed in Appendix B. The principles of Helsinki are 
addressed through the protocol and through appendices containing requirements for informed 
consent and Investigator responsibilities.
13.1
IRB and/or IEC Approval
IRBs and IECs must be constituted according to the applicable state and federal/local requirements 
of each participating region. The Sponsor or designee will require documentation noting all names 
and titles of members who make up the respective IRB or IEC. If any member of the IRB or IEC 
has direct participation in this study, written notification regarding his or her abstinence from 
voting must also be obtained. Those Americas sites unwilling to provide names and titles of all 
members due to privacy and conflict of interest concerns should instead provide a Federal Wide 
Assurance Number or comparable number assigned by the Department of Health and Human 
Services.
The Sponsor or designee will supply relevant documents for submission to the respective IRB or 
IEC for the protocol’s review and approval. This protocol, the Investigator’s Brochure, a copy of 
the informed consent form, and, if applicable, subject recruitment materials and/or advertisements 
and other documents required by all applicable laws and regulations, must be submitted to a 
central or local IRB or IEC for approval. The IRB’s or IEC’s written approval of the protocol and 
subject informed consent must be obtained and submitted to the Sponsor or designee before 
commencement 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/notify site once the Sponsor has 
confirmed the adequacy of site regulatory documentation and, when applicable, the Sponsor has 
received permission from competent authority to begin the trial. Until the site receives 
drug/notification no protocol activities, including screening, may occur.
Sites must adhere to all requirements stipulated by their respective IRB or IEC. This may include 
notification to the IRB or IEC regarding protocol amendments, updates to the informed consent

13.2
Subject 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, subject authorization form (if 
applicable), and subject information sheet (if applicable) describe the planned and permitted uses, 
transfers, and disclosures of the subject’s personal and personal health information for purposes of 
conducting the study. The informed consent form and the subject information sheet (if applicable) 
further explain the nature of the study, its objectives, and potential risks and benefits, as well as the 
date informed consent is given. The informed consent form will detail the requirements of the 
participant and the fact that he is free to withdraw at any time without giving a reason and without 
prejudice to his or her further medical care.
The Investigator is responsible for the preparation, content, and IRB or IEC approval of the 
informed consent form and, if applicable, the subject authorization form. The informed consent 
form, subject authorization form (if applicable), and subject information sheet (if applicable) must 
be approved by both the IRB or IEC and the Sponsor prior to use.
The informed consent form, subject authorization form (if applicable), and subject information 
sheet (if applicable) must be written in a language fully comprehensible to the prospective subject. 
It is the responsibility of the Investigator to explain the detailed elements of the informed consent 
form, subject authorization form (if applicable), and subject information sheet (if applicable) to the 
subject. Information should be given in both oral and written form whenever possible and in the 
manner deemed appropriate by the IRB or IEC. In the event the subject is not capable of rendering
adequate written informed consent, then the subject’s legally acceptable representative may 
provide such consent for the subject in accordance with applicable laws and regulations.
The subject, or the subject’s legally acceptable representative, must be given ample opportunity to: 
(1) inquire about details of the study, and (2) decide whether or not to participate in the study. If the 
subject, or the subject’s legally acceptable representative, determines he or she will participate in 
the study, then the informed consent form and subject authorization form (if applicable) must be 
signed and dated by the subject, or the subject’s legally acceptable representative, at the time of 
consent and prior to the subject entering into the study. The subject or the subject’s legally 
acceptable representative should be instructed to sign using their legal names, not nicknames, 
using blue or black ballpoint ink. The Investigator must also sign and date the informed consent 
form and subject authorization (if applicable) at the time of consent and prior to subject entering 
into the study; however, the Sponsor may allow a designee of the Investigator to sign to the extent
permitted by applicable law.
Once signed, the original informed consent form, subject authorization form (if applicable), and 
subject information sheet (if applicable) will be stored in the Investigator’s site file. The 
Investigator must document the date the subject signs the informed consent in the subject’s 
medical record. Copies of the signed informed consent form, the signed subject authorization form 
(if applicable), and subject information sheet (if applicable) shall be given to the subject.

All revised informed consent forms must be reviewed and signed by relevant subjects or the 
relevant subject’s legally acceptable representative in the same manner as the original informed 
consent. The date the revised consent was obtained should be recorded in the subject’s medical 
record, and the subject should receive a copy of the revised informed consent form.
Subjects who consented and provided a PGx sample for DNA and RNA analysis can withdraw 
their consent and request disposal of a stored sample at any time prior to analysis. Notify Sponsor 
of consent withdrawal.
13.3
Subject Confidentiality
The Sponsor and designees 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 identification number. As 
permitted by all applicable laws and regulations, 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’s unique 
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 (eg, FDA, Medicines and Healthcare products Regulatory Agency, 
Pharmaceuticals and Medical Devices Agency), 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 13.2).
Copies of any subject source documents that are provided to the Sponsor must have certain 
personally identifiable information removed (ie, subject name, address, and other identifier fields 
not collected on the subject’s CRF).
13.4
Publication, Disclosure, and Clinical Trial Registration Policy
13.4.1 Publication and Disclosure
The Investigator is obliged to provide the Sponsor with complete test results and all data derived 
by the Investigator from the study. During and after the study, only the Sponsor may make study 
information available to other study Investigators or to regulatory agencies, except as required by 
law or regulation. Except as otherwise allowable in the clinical study site agreement, any public 
disclosure (including publicly accessible websites) related to the protocol or study results, other 
than study recruitment materials and/or advertisements, is the sole responsibility of the Sponsor.
The Sponsor may publish any data and information from the study (including data and information 
generated by the investigator) without the consent of the Investigator. Manuscript authorship for 
any peer-reviewed publication will appropriately reflect contributions to the production and 
review of the document. All publications and presentations must be prepared in accordance with

this section and the Clinical Study Site Agreement. In the event of any discrepancy between the 
protocol and the Clinical Study Site Agreement, the Clinical Study Site Agreement will prevail.
13.4.2 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 all 
interventional clinical trials it Sponsors anywhere in the world on ClinicalTrials.gov and/or other 
publicly accessible websites before start of study, as defined in Takeda Policy/Standard. Takeda 
contact information, along with Investigator’s city, state (for Americas Investigators), country, and 
recruiting status will be registered and available for public viewing. 
For some registries, Takeda will assist callers in locating study 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 caller asks additional 
questions beyond the topic of trial enrollment, they should be referred to the Sponsor.
Any Investigator who objects to the Sponsor providing this information to callers must provide the 
Sponsor with a written notice requesting that their information not be listed on the registry site.
13.4.3 Clinical Trial Results Disclosure 
Takeda will post the results of clinical trials on ClinicalTrials.gov or other publicly accessible 
websites, as required by Takeda Policy/Standard, applicable laws and/or regulations.
13.5
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 Sponsor’s 
designee will obtain clinical study insurance against the risk of injury to study subjects. Refer to 
the study site 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 Sponsor’s designee.

DATA HANDLING AND RECORDKEEPING
The full details of procedures for data handling will be documented in the Data Management Plan. 
AEs, medical history, and concurrent conditions will be coded using the Medical Dictionary for 
Regulatory Activities (MedDRA). Drugs will be coded using the World Health Organization Drug 
Dictionary.
15.1
CRFs (Electronic and Paper)
Completed CRFs are required for each subject who signs an informed consent.
The Sponsor or its designee will supply investigative sites with access to CRFs. The Sponsor will 
make arrangements to train appropriate site staff in the use of the CRF. These forms are used to 
transmit the information collected in the performance of this study to the Sponsor and regulatory 
authorities. CRFs must be completed in English. Data are transcribed directly onto CRFs.
After completion of the entry process, computer logic checks will be run to identify items, such as 
inconsistent dates, missing data, and questionable values. Queries may be issued by Takeda 
personnel (or designees) and will be answered by the site. 
Corrections are recorded in an audit trail that captures the old information, the new information, 
identification of the person making the correction, the date the correction was made, and the reason 
for change. Reasons for significant corrections should additionally be included. 
The Principal Investigator must review the CRFs for completeness and accuracy and must sign and 
date the appropriate CRFs as indicated. Furthermore, the Investigator must retain full 
responsibility for the accuracy and authenticity of all data entered on the CRFs.
After the lock of the clinical study database, any change of, modification of, or addition to the data 
on the CRFs should be made by the Investigator with use of change and modification records of 
the CRFs. The Principal Investigator must review the data change for completeness and accuracy, 
and must sign and date.
CRFs will be reviewed for completeness and acceptability at the study site during periodic visits 
by study monitors. The Sponsor or its designee will be permitted to review the subject’s medical 
and hospital records pertinent to the study to ensure accuracy of the CRFs. The completed CRFs 
are the sole property of the Sponsor and should not be made available in any form to third parties, 
except for authorized representatives of appropriate governmental health or regulatory authorities, 
without written permission of the Sponsor.
15.2
Record Retention
The Investigator agrees to keep the records stipulated in Section 15.1 and those documents that 
include (but are not limited to) the study-specific documents, the identification log of all 
participating subjects, medical records, temporary media such as thermal sensitive paper, source 
worksheets, all original signed and dated informed consent forms, subject authorization forms 
regarding the use of personal health information (if separate from the informed consent forms), 
electronic copy of CRFs, including the audit trail, and detailed records of drug disposition to

documentation printed on degradable thermal sensitive paper should be photocopied by the site 
and filed with the original in the subject’s chart to ensure long-term legibility. Furthermore, ICH 
E6 Section 4.9.5 requires the Investigator to retain essential documents specified in ICH E6 
(Section 8) until at least 2 years after the last approval of a marketing application for a specified 
drug indication being investigated or, if an application is not approved, until at least 2 years after 
the investigation is discontinued and regulatory authorities are notified. In addition, ICH E6 
Section 4.9.5 states that the study records should be retained until an amount of time specified by 
applicable regulatory requirements or for a time specified in the Clinical Study Site Agreement 
between the Investigator and Sponsor.
Refer to the Clinical Study Site Agreement for the Sponsor’s requirements on record retention. 
The Investigator and the head of the institution should contact and receive written approval from 
the Sponsor before disposing of any such documents.

Appendix B
Responsibilities of the Investigator
Clinical research studies sponsored by the Sponsor are subject to ICH GCP and all the applicable 
local laws and regulations. The responsibilities imposed on Investigators by the FDA are 
summarized in the “Statement of Investigator” (Form FDA 1572), which must be completed and 
signed before the Investigator may participate in this study.
The Investigator agrees to assume the following responsibilities by signing a Form FDA 1572:
1. Conduct the study in accordance with the protocol.
2. Personally conduct or supervise the staff that will assist in the protocol.
3. If the Investigator/institution retains the services of any individual or party to perform 
trial-related duties and functions, the Investigator/institution should ensure that this individual 
or party is qualified to perform those trial-related duties and functions and should implement 
procedures to ensure the integrity of the trial-related duties and functions performed and any 
data generated.
4. Ensure that study related procedures, including study specific (nonroutine/nonstandard panel) 
screening assessments are NOT performed on potential subjects, prior to the receipt of written 
approval from relevant governing bodies/authorities.
5. Ensure that all colleagues and employees assisting in the conduct of the study are informed of 
these obligations.
6. Secure prior approval of the study and any changes by an appropriate IRB/IEC that conform to 
21 CFR Part 56, ICH, and local regulatory requirements.
7. Ensure that the IRB/IEC will be responsible for initial review, continuing review, and approval 
of the protocol. Promptly report to the IRB/IEC all changes in research activity and all 
anticipated risks to subjects. Make at least yearly reports on the progress of the study to the 
IRB/IEC, and issue a final report within 3 months of study completion.
8. Ensure that requirements for informed consent, as outlined in 21 CFR Part 50, ICH and local 
regulations, are met.
9. Obtain valid informed consent from each subject who participates in the study, and document 
the date of consent in the subject’s medical chart. Valid informed consent is the most current 
version approved by the IRB/IEC. Each informed consent form should contain a subject 
authorization section that describes the uses and disclosures of a subject’s personal 
information (including personal health information) that will take place in connection with the 
study. If an informed consent form does not include such a subject authorization, then the 
Investigator must obtain a separate subject authorization form from each subject or the 
subject’s legally acceptable representative.
10. Prepare and maintain adequate case histories of all persons entered into the study, including 
CRFs, hospital records, laboratory results, etc, and maintain these data for a minimum of 
2 years following notification by the Sponsor that all investigations have been discontinued or 
that the regulatory authority has approved the marketing application. The Investigator should

Pregnancy and Contraception
Contraception and Pregnancy Avoidance Procedure
Male Subjects and Their Female Partners
From signing of informed consent, throughout the duration of the study, and for 90 days after last 
dose of study drug, male subjects who are sexually active with a female partner of childbearing 
potential* must use barrier contraception (eg, condom with spermicide). In addition, they must be 
advised not to donate sperm throughout the duration of the study, and for 90 days after last dose of 
study drug. Females of childbearing potential who are partners of male subjects are also advised to 
use additional contraception as shown in the list containing highly effective contraception below. 
Total abstinence (no sexual intercourse) may be considered an acceptable method of birth control 
if it agrees with the subject’s preferred and usual lifestyle.
Definitions and Procedures for Contraception and Pregnancy Avoidance
The following definitions apply for contraception and pregnancy avoidance procedures.
* A woman is considered a woman of childbearing potential (WOCBP), ie, fertile, following 
menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilization 
methods include hysterectomy, and bilateral oophorectomy. A postmenopausal state is defined as 
no menses for 12 months without an alternative medical cause.
The following procedures apply for contraception and pregnancy avoidance.
1. Highly effective methods of contraception are defined as “those, alone or in combination, that 
result in a low failure rate (ie, less than 1% failure rate per year when used consistently and 
correctly). Acceptable methods of contraception are: 

Non-Hormonal Methods: 
–
Intrauterine device (IUD).
–
Bilateral tubal occlusion.
–
Vasectomised subject (has received medical assessment of the surgical success).
–
True sexual abstinence, only if this is in line with the preferred and usual lifestyle of the 
subject. True abstinence is defined as refraining from heterosexual intercourse during 
the entire period of the study, from 1 month prior to the first dose until 90 days after the 
last dose.

Hormonal Methods:
–
Combined (estrogen and progestogen) hormonal contraception associated with 
inhibition of ovulation initiated at least 3 months prior to the first dose of study drug 
OR combined with a barrier method (male condom, female condom or diaphragm) if 
for shorter duration until she has been on contraceptive for 3 months;

Oral.

3. Subjects will be provided with information on highly effective methods of contraception as 
part of the subject informed consent process and will be asked to sign a consent form stating 
that they understand the requirements for avoidance of pregnancy and sperm donation during 
the course of the study.
4. During the course of the study, all subjects will receive continued guidance with respect to the 
avoidance of pregnancy and sperm donation as part of the study procedures. Such guidance 
should include a reminder of the following:
a.
contraceptive requirements of the study
b. reasons for use of barrier methods (ie, condom) in subjects with pregnant 
partners
c.
assessment of subject compliance through questions such as
i. Have you used the contraception consistently and correctly since the last visit?
ii. Have you forgotten to use contraception since the last visit?

Procedures for Reporting Drug Exposure During Pregnancy and Birth Events
Women will not be included in this study.
If a female partner of a subject becomes pregnant during the subject’s participation in this study, 
the Sponsor must be contacted immediately by faxing a completed pregnancy form to the Takeda 
Global Pharmacovigilance department or designee (see Section 14.1.1). 
Any pregnancies in the partner of a male subject during the study or for 90 days after the last dose, 
should also be recorded following authorization from the subject’s partner.
If the female partner of a subject agrees to the primary care physician being informed, the 
Investigator should notify the primary care physician that the female partner became pregnant at 
the time when her partner (male subject) was participating in a clinical study and provide details of 
the study drug the subject received (blinded or unblinded, as applicable).
All pregnancies of female partners of subjects on active study drug (including comparator, if 
applicable) will be followed up to final outcome, using the pregnancy form. Pregnancies will 
remain blinded to the study team. The outcome, including any premature termination, must be 
reported to the Sponsor. An evaluation after the birth of the child will also be conducted.
