STUDY SUMMARY
Name of Sponsor:
Millennium Pharmaceuticals, Inc.
Compound:
TAK-931
Title of Protocol:
A Phase 1, Open-Label Study to Assess the Relative 
Bioavailability, Effect of Food, and Gastric pH 
Modification on the Pharmacokinetics of TAK-931 in 
Patients With Advanced Solid Tumors
IND No.:
127,176
EudraCT No.:
2017-004629-34
Study Number: TAK-931-1003
Phase: 1
Study Design:
Part 1: Assessment of Relative Bioavailability of TAK-931 Tablets in Reference to Powder-in-Capsule
Approximately 20 patients (to ensure 14-16 patients evaluable for pharmacokinetics [PK]) will be randomized in a 
crossover fashion to receive in Cycle 0 a single dose of TAK-931 80 mg powder-in-capsule (PIC) or tablet on Day 1 
and a single dose of TAK-931 80 mg with the alternate formulation on Day 3 (PIC to tablet, or tablet to PIC; 
n of ~10/sequence). Blood samples will be collected predose and up to 48 hours postdose at predetermined time points 
to measure plasma drug concentrations to evaluate the relative bioavailability of TAK-931 tablets in reference to the 
PIC formulation. There will be no TAK-931 dosing on Day 2 or Day 4. Starting on Day 5, patients will continue to 
receive TAK-931 50 mg PIC once daily (QD) for 12 days followed by a 7-day rest period. 
Starting at Cycle 1, patients will 50 mg PIC QD for 14 days, followed by 7-day rest period, in 21-day treatment cycles 
until one of the discontinuation criteria is met.
Part 2: Assessment of the Effect of Food and Esomeprazole, a Proton Pump Inhibitor, on the PK of TAK-931 as a 
Tablet
After the preliminary PK data from part 1 have been analyzed to estimate the relative bioavailability of the tablet 
formulation in reference to PIC, the dose of TAK-931 tablet will be calculated to provide total exposure (area under 
the concentration-time curve [AUC]) comparable to the 80-mg dose of PIC. In part 2, approximately 24 patients (to 
ensure 14-16 patients evaluable for PK) will be randomized in a crossover fashion to receive in Cycle 0 a single dose 
of the TAK-931 tablet formulation with or without a standard high-fat breakfast on Day 1, with the alternate food 
intake condition and dosing on Day 3 (fasted to fed or fed to fasted; n of ~12/sequence). Blood samples will be 
collected predose and for up to 48 hours postdose at predetermined time points to measure plasma drug concentrations 
to characterize the effect of food on the PK profile of TAK-931 tablet. Starting from Day 5, patients will receive 
esomeprazole 40 mg QD through Day 13. On Day 12, each patient will receive a single dose of the TAK-931 tablet 
formulation, and PK samples will be collected up to 48 hours postdose (Day 14 predose). Starting on Day 14, patients 
will continue to receive TAK-931 tablets at a dose expected to achieve exposures comparable to 50 mg PIC QD for 
11 days, followed by a 7-day rest period, until a discontinuation criterion is met. 
Starting at Cycle 1, patients will receive the TAK-931 tablet formulation at a dose expected to achieve exposures 
comparable to 50 mg PIC QD for 14 days, followed by 7-day rest period, in 21-day treatment cycles.
Primary Objectives:
Part 1

Estimate the relative bioavailability of the tablet formulation of TAK-931 in reference to the PIC 
formulation. 
Part 2

Assess the effect of a high-fat meal on the single dose PK of TAK-931 administered as the tablet formulation. 

Assess the effect of esomeprazole, a proton pump inhibitor (PPI) on the single dose PK of TAK-931 
administered as the tablet formulation.

Protocol 
21 June 2018
Secondary Objectives:
Part 1

Further characterize the PK of TAK-931 administered as PIC or the tablet formulation. 

Assess the safety and tolerability of TAK-931 administered as the tablet and PIC formulations. 

Assess the antitumor activity of TAK-931 in patients with locally advanced or metastatic solid tumors.
Part 2

Further characterize the PK of TAK-931 administered as the tablet formulation under fasted and fed 
conditions. 

Further characterize the PK of TAK-931 administered as the tablet formulation in the presence or absence of 
esomeprazole, a PPI. 

Assess the safety and tolerability of TAK-931 administered as the tablet formulation under fed and fasted 
conditions.

Assess the antitumor activity of TAK-931 in patients with locally advanced or metastatic solid tumors.
Subject Population: Adult patients with histologically or cytologically confirmed metastatic or locally advanced or 
metastatic solid tumors for whom there is no available standard treatment with proven survival benefit, this therapy is 
not indicated, or it is refused by the patient.
Number of Patients:
A total of approximately 44 patients: 20 patients to obtain 
14 to 16 evaluable patients in part 1 and 24 patients to obtain 
14 to 16 evaluable patients in part 2.
Number of Sites: 
Estimated total: 3 to 4 sites in The Netherlands
Doses:
Part 1: 80 mg single dose on Day1 and Day 3 respectively 
followed by 50 mg QD thereafter. 
Part 2: Tablet single dose providing an AUC comparable to 
the 80-mg single dose of PIC on Day 1, Day 3, and Day 12 
followed by a tablet QD dose providing an AUC 
comparable to 50-mg dose of PIC.
Route of Administration:
Oral
Duration of Treatment:
Patients may receive TAK-931 until they experience 
progressive disease or unacceptable toxicity or until any 
other discontinuation criterion is met. The maximum 
scheduled duration of treatment will be 1 year; however, 
patients receiving clinical benefit (per the investigator and 
as agreed by the sponsor’s medical monitor) can continue 
on treatment beyond 1 year with the explicit approval of the 
sponsor’s medical monitor.
Period of Evaluation:
Patients will be followed for safety for approximately 
30 days after their last dose of study drug or until the 
start of subsequent anticancer therapy, whichever 
occurs first. 
All patients will be followed for progression-free 
survival (PFS).
It is anticipated that this study will last for 
approximately 24 months. 
Main Criteria for Inclusion:

Adult patients with histologically or cytologically confirmed metastatic or locally advanced or metastatic solid 
tumors for whom there is no available standard treatment with proven survival benefit, this therapy is not 
indicated, or it is refused by the patient. 

Eastern Cooperative Oncology Group performance status of 0 to 1.

Adequate bone marrow reserve and renal and hepatic function based on the following laboratory parameters: 
–
Absolute neutrophil count ≥1.5 × 109/L, platelet count ≥75.0 × 109/L, and hemoglobin ≥85 g/L.

Sample Size Justification:
The sample size calculation is based on the expected 2-sided 90% CI for the difference in the paired, log transformed 
AUC (or Cmax) means of TAK-931 administered as tablet and PIC formulations. On the basis of preliminary data 
obtained from Study TAK-931-1002, the within-subject coefficient of variation was estimated to be 35.0% for AUC 
and 36.9% for Cmax. Assuming the true/assumed AUC (or Cmax) ratio is 1.0, with a sample size of 14 evaluable 
patients, the 90% CI of the ratio of geometric means is expected to be (0.795-1.257) for AUC and (0.786-1.272) for 
Cmax on the basis of the previously discussed variance assumptions. If the ratio is X, the 90% CI of the ratio of 
geometric means is expected to be within (0.795X-1.257X) for AUC and (0.786X-1.272X) for Cmax. Patients who are 
not PK-evaluable may be replaced to ensure the availability of 14 to 16 PK-evaluable patients for the final analysis of 
part 1 and part 2, respectively.

INTRODUCTION
4.1
Background
TAK-931 is a highly potent and selective inhibitor of the cell division cycle 7 (CDC7) kinase. 
CDC7 is a serine/threonine kinase that contributes to initiation of DNA replication by 
phosphorylating the minichromosome maintenance complex 2 (MCM2) [1,2]. Kinase activity of 
CDC7 is controlled by its binding protein DBF4 in a cell cycle-dependent manner [3]. Recent 
studies revealed that CDC7 is also involved in DNA damage response (DDR) and DNA 
replication, suggesting that CDC7 plays important roles in both cell proliferation during the 
S phase and genomic stability in DDR [4-7].
Furthermore, elevated CDC7 expression has been reported in various cancers and correlates with 
poor prognosis, such as in diffuse large B-cell lymphoma, oral squamous carcinoma, and breast, 
colon, colorectal, ovarian, and lung tumors [8-12]. However, it is not clear to what extent this 
increased expression reflects proliferative potential [13].
In vitro inhibition of the CDC7/DBF4 kinase complex arrests cell proliferation and induces 
apoptosis in cancer cell lines [14]. The major reason why the inhibition of the CDC7/DBF4 kinase 
complex is highly relevant for cancer is that activation of diverse oncogenes and loss of some 
tumor suppressors evoke replication stress and consequent DNA damage that triggers the 
checkpoint responses of specific signaling cascades, as demonstrated in cell culture experiments 
and in analyses of clinical specimens from a range of human malignancies [15,16]. Taken together, 
these data suggest that CDC7 kinase inhibitors present a novel class of molecular targets for cancer 
therapy [17].
Given that CDC7 is responsible for 2 key functions of DNA replication and DDR, CDC7 appears 
to be a critical gene for proliferation and survival of cancer cells, and inhibition of CDC7 is 
expected to be antiproliferative and induce apoptosis in a broad range of cancers. Given the dual 
mechanism of action of CDC7, inhibitors of CDC7 may also produce clinical activity both as 
single agents and in combination with other DNA-damaging drugs.

Protocol 
21 June 2018
TAK-931 exhibited nonlinear PK following oral dosing in rats and dogs with single-dose 
maximum observed concentration (Cmax) and ea under the plasma concentration-time curve 
(AUC) from time 0 to 24 hours (AUC24) increasing in a greater-than-dose-proportional manner at 
higher doses. No accumulation of TAK-931 was observed in either species. 
TAK-931 has high permeability and is a substrate for breast cancer resistance protein, but is not 
likely a substrate for P-glycoprotein (P-gp) on the basis of transcellular transport investigations 
across Caco-2 cell monolayers. Additionally, TAK-931 may have a weak inhibitory effect on 
P-gp–mediated efflux activity (IC50 >100 ∀M). The drug-drug interaction (DDI) potential of 
TAK-931 with P-gp substrates and inhibitors is low.
In an in vitro study, plasma protein binding was 59% to 62% in mice, 73% to 74% in rats, 57% to 
58% in dogs, and 73% to 74% in humans, with no concentration dependency observed from 0.01 
to 1 ∀g/mL.
The in vitro oxidative metabolism of TAK-931 was evaluated using liver microsomes from CD-1 
mice, Sprague-Dawley rats, beagle dogs, cynomolgus monkeys, and humans. TAK-931 was 
metabolized primarily to the unidentified metabolite UK-1 and, to a lesser extent, UK-2. There 
was no metabolite unique to human liver microsomes through oxidative metabolism.
Evaluation of the in vitro metabolism of TAK-931 in the presence of uridine 
5'-diphosphateglucuronic acid showed that the compound is metabolized through glucuronidation 
by liver microsomes from all species except dogs (mice, rats, monkeys, and humans).
Investigations into cytochrome P450 (CYP) enzyme-mediated metabolism showed that CYP2D6 
and CYP3A are the main CYPs involved in the metabolism of TAK-931. There is a DDI potential 
with uridine 5'-diphospho-glucuronosyltransferase inducers; however, the DDI potential with 
CYP inhibitors, though they are involved in metabolism, is unlikely. TAK-931 is unlikely to cause 
DDIs with concomitant medications metabolized via CYP isozymes at Cmax values <800 ng/mL.

4.1.1.3
Nonclinical Toxicology
The TK profile and systemic toxic potential of TAK-931 has been well defined in Sprague-Dawley 
rats and beagle dogs.
The primary dose-limiting toxicities (DLTs), particularly in the dog, appear to be associated with 
Cmax and are closely associated with the observed cardiovascular changes. The effects on blood 
pressure (BP) and heart rate (HR) were dose-dependent and clearly related to compound 
concentration in plasma. The mechanism is likely related to the off-target pharmacological effects 
of TAK-931. It has been confirmed that the effects of TAK-931 on HR and BP are monitorable and 
reversible upon clearance of TAK-931. In addition, renal injury (obstructive nephropathy) was 
confirmed to be a DLT in rats, although similar changes were not observed in dogs. Renal effects 
of TAK-931 were monitorable with clinical chemistry, and renal tubular damage is considered to 
be reversible.
The target organ toxicities after repeated dosing of TAK-931 were largely similar in rats and dogs 
and were generally consistent with inhibition of CDC7 activity. Test article-related findings 
included the hematopoietic and lymphoid systems, gastrointestinal (GI) mucosa, and reproductive 
organs. Decreased white blood cell (WBC) count or single cell necrosis in the GI mucosa appeared 
with minimal degree at lower doses and severity increased with dose level. All target organ 
toxicities observed in the repeat-dose studies were generally monitorable and reversible, except for 
the effect on germ cells.
On the basis of these results, the toxicology studies conducted with TAK-931 support the proposed 
clinical program in adult patients with advanced malignancies. The nonclinical toxicology profile 
demonstrated target organ toxicity that was generally considered to be monitorable and reversible. 
The primary Cmax-related toxicity was cardiovascular effects (decreased BP with reflecting 
tachycardia). The DLTs related to total exposure were effects on the GI mucosa and lymphoid 
systems consistent with pharmacology-mediated CDC7 inhibition. 
Details of these studies are provided in the current TAK-931 IB. 
4.1.2
Clinical Experience
TAK-931 is being evaluated in 2 ongoing studies: TAK-931-1002, a phase 1 first-in-human (FIH) 
study in adult Japanese patients with histologically confirmed solid tumors; and TAK-931-2001, a 
phase 2 study in patients with metastatic pancreatic cancer or metastatic colon cancer. After 
TAK-931 50 mg once daily (QD) was established as the maximum tolerated dose (MTD) under 
Schedule A (14 days of treatment followed by 7 days of rest in a 21-day cycle) in study 
TAK-931-1002, an expansion cohort was added at that dose and 16 additional patients were 
enrolled. As of 04 January 2018, a total of 49 patients had received at least 1 dose of TAK-931, 
administered as a single agent in Schedule A (n = 25), Schedule B (n=12, QD for 7 consecutive 
days followed by another 7 days of rest and repeated in a 28-day cycle), and Schedule D (n = 12, 
QD continuously in a 21-day cycle).

Safety
DLTs occurred in 5 patients in Study TAK-931-1002. Two DLTs were Grade 4 neutropenia at 
60 mg QD for 14 days in a 21-day cycle. Three DLTs were febrile neutropenia events (all 
Grade 3): 1 occurred at 50 mg under dosing Schedule A and the other 2 at 80 mg under dosing 
Schedule B. Four of these 5 DLTs were serious, and all 5 resolved. 
A total of 20 serious treatment-emergent adverse events (TEAEs), regardless of causality, were 
reported in 12 patients treated in Study TAK-931-1002, as of the 04 January 2018 cutoff date. Of 
these, 3 SAEs were reported in 2 patients in the 60 mg cohort (neutropenia, nausea, decreased 
appetite), and 1 SAE was reported in the 40 mg cohort (pleural effusion). 
Grade ≥3 TEAEs reported in 2 or more patients in Study TAK-931-1002 as of 04 January 2018 
included neutropenia (37%), leukopenia (12%), WBC count decreased (10%), febrile neutropenia 
(6%), anemia (4%), and decreased appetite (4%). Seven of the 23 total patients treated developed 
at least 1 Grade ≥3 TEAE. There were no deaths. 
The most common TEAEs regardless of causality reported in at least 2 patients in Study 
TAK-931-1002 as of the 04 January 2018 cutoff date included nausea (49%), neutropenia (43%), 
WBC count decreased (29%), decreased appetite (27%), alopecia (22%), vomiting (20%), 
diarrhoea (18%), anaemia (16%), leukopenia (16%), uncoded (16%), malaise (14%), pyrexia 
(14%), oedema peripheral (12%), constipation (10%), fatigue (10%), and hypoalbuminaemia 
(10%). Forty-eight of the 49 total patients treated developed at least 1 TEAE. 
Refer to the IB for additional information. 
4.1.2.2
PK
Absorption of TAK-931 was fast following single or multiple oral dose administrations, with a 
median time of first occurrence of Cmax (tmax) of 1 to 4 hours. Systemic exposures (AUC) of 
TAK-931 increased in approximately a dose-proportional manner over the range of 20 to 80 mg 
QD. The interpatient variability (coefficient of variation [%CV]) in TAK-931 Cmax was <50% and 
AUC ≤30%. TAK-931 showed minimal accumulation following multiple-dose administration, 
consistent with a mean terminal disposition phase half-life (t1/2z) of 4.3 to 6.2 hours. 
4.1.3
Benefits and Risks
The current study is an open-label clinical pharmacology study to assess the relative 
bioavailability, effect of food, and gastric pH modification on the PK of TAK-931 in patients with 
advanced solid tumors. Some tumor indications are suggested as preferred based on the 
information in Section 4.1.1.1. Regardless, patients should have exhausted available standard 
therapeutic options with a proven survival benefit. Because Studies TAK-931-1002 and 
TAK-931-2001 are in progress and only a limited number of patients have been treated with 
TAK-931, there are no established benefits of this drug and the available safety information for the 
proposed dose is described in Section 4.1.2.1. 
Based on the available clinical and preclinical data, it is reasonable to consider this trial for patients 
with advanced solid tumors for whom there is no available standard treatment with proven survival

benefit. Based on the nonclinical data in Section 4.1.1.1, some indications may have a higher 
probability of clinical benefit: high-grade serous ovarian cancer, uterine carcinosarcoma, 
squamous esophageal cancer, squamous NSCLC, squamous head and neck cancers, rectal 
adenocarcinoma, and in general tumors with known TP53 gene mutations. For any of these 
preferred indications, patients should have exhausted standard therapeutic options with a proven 
survival benefit.
4.2
Rationale for the Proposed Study
This study will enroll approximately 44 patients. In part 1, approximately 20 patients will be 
enrolled to obtain 14 to 16 evaluable patients to assess the relative bioavailability of the TAK-931 
tablet formulation in reference to the powder-in-capsule (PIC) formulation. In part 2, 
approximately 24 patients will be enrolled to obtain 14 to 16 evaluable patients to assess the effects 
of food and esomeprazole on the PK of TAK-931 tablets. 
4.2.1
Part 1: Assessment of Relative Bioavailability of TAK-931 Tablets in Reference to 
PIC
In addition to the PIC formulation, a tablet formulation of TAK-931 has been developed for 
clinical use. The rationale for conducting this study is to characterize the relative bioavailability of 
TAK-931 administered as a tablet in reference to the PIC formulation. A tablet of 80 mg is the 
highest dose strength being evaluated in clinical studies. The prototype tablet was designed as an 
immediate-release formulation and possesses a similar rapid dissolution profile to the PIC 
formulation under acidic conditions. In vitro dissolution profiles for 10, 25, and 80 mg tablets and 
capsules are considered similar at low pH. Part 1 of this study will estimate the relative 
bioavailability of the tablet in reference to the PIC formulation to enable the transition from PIC to 
tablet in clinical development. 
4.2.2
Part 2: Assessment of the Effect of Food and Esomeprazole on PK of TAK-931 as 
Tablet
Food can alter the rate or extent of absorption or both of orally administered antineoplastic agents, 
which can have clinical implications in the treatment of patients with cancer. Ingestion of food has 
several physiologic GI effects including delayed gastric emptying, stimulated bile flow, changed 
GI pH, and increased splanchnic blood flow. Food may also alter the bioavailability of a drug by 
physically or chemically interacting with a dosage form or a drug substance. Because food may 
change the bioavailability of a drug, a food effect study is being conducted to assess the effects of 
food on the rate and extent of drug absorption when the drug is administered after a high-calorie 
and high-fat meal has been ingested. This part of the study will therefore evaluate the effect of a 
high-fat meal on the PK of TAK-931 administered as the tablet formulation.
TAK-931 (basic pKa of 6.23 and an acidic pKa of 11.1) exhibits pH-dependent solubility with low 
aqueous solubility at basic pH. Therefore, it is possible that concomitant administration of gastric 
acid-reducing agents, such as proton pump inhibitors (PPIs) and histamine-2 (H2) receptor 
antagonists, could decrease TAK-931 systemic exposures. This part of the study is therefore

designed to additionally evaluate the effect of multiple-dose administrations of esomeprazole, a 
PPI, on the PK of TAK-931 administered as a tablet formulation.
Part 2 of this study will be initiated only after the preliminary data from part 1 are available to 
estimate the relative bioavailability of the tablet formulation in reference to PIC. Based on this 
estimate, the dose of TAK-931 tablets will be calculated to provide total exposure (AUC) 
comparable to that achieved at the 80 mg dose of PIC. Part 2 will evaluate the effect of food and 
esomeprazole, a PPI, on the PK of the tablet formulation at the above calculated dose level to 
ensure that assessment of food effect and the effect of esomeprazole are being performed at a 
clinically relevant dose of TAK-931 as tablet formulation.

STUDY DESIGN
6.1
Overview of Study Design
6.1.1
Part 1: Assessment of Relative Bioavailability of TAK-931 Tablet in Reference to PIC
Approximately 20 patients (to ensure 14-16 patients evaluable for PK) will be randomized in a 
crossover fashion to receive a single dose of TAK-931 80 mg PIC or tablet on Cycle 0 Day 1 and a 
single dose of TAK-931 80 mg with the alternate formulation on Day 3 (PIC to tablet, or tablet to 
PIC; n of ~10/sequence). Blood samples will be collected predose and up to 48 hours postdose at 
predetermined time points to measure plasma drug concentrations to evaluate the relative 
bioavailability of TAK-931 tablets in reference to the PIC formulation. There will be no TAK-931 
dosing on Day 2 or Day 4. Starting on Day 5, patients will continue to receive TAK-931 50 mg 
PIC QD for 12 days followed by a 7-day rest period. 
Starting at Cycle 1, patients will receive 50 mg PIC QD for 14 days followed by 7-day rest period 
in 21-day treatment cycles until one of the discontinuation criteria is met.

6.1.2
Part 2: Assessment of the Effect of Food and Esomeprazole, a PPI, on the PK of 
TAK-931 as a Tablet
After the preliminary PK data from part 1 have been analyzed to estimate the relative 
bioavailability of the tablet formulation in reference to PIC, the single dose of TAK-931 tablet to 
be used on Cycle 0 Day 1, Day 3, and Day 12 will be calculated to provide total exposure (AUC) 
comparable to the 80-mg dose of PIC. In part 2, approximately 24 patients (to ensure 
14-16 patients evaluable for PK) will be randomized in a crossover fashion to receive a single dose 
of the TAK-931 tablet formulation with or without a standard high-fat breakfast on Cycle 0 Day 1, 
with the alternate food intake condition and dosing on Day 3 (fasted to fed or fed to fasted; n of
~12/sequence). Blood samples will be collected predose and for up to 48 hours postdose at 
predetermined time points to measure plasma drug concentrations to characterize the effect of food 
on the PK of TAK-931 tablet. Starting from Day 5, patients will receive esomeprazole 40 mg QD 
through Day 13. On Day 12, each patient will receive a single dose of the TAK-931 tablet 
formulation, and PK samples will be collected up to 48 hours postdose (Day 14 predose). Starting 
on Day 14, patients will continue to receive TAK-931 tablets at a dose expected to achieve 
exposures comparable to 50 mg PIC QD for 9 days followed by a 7-day rest period until a 
discontinuation criterion is met. 
Starting at Cycle 1, patients will receive the TAK-931 tablet formulation at a dose expected to 
achieve exposures comparable to 50 mg PIC QD for 14 days followed by 7-day rest period in 
21-day treatment cycles. 
This study is an open-label, multicenter, phase 1 study of TAK-931 in adult patients with locally 
advanced or metastatic solid tumors. The patient population will consist of adults previously 
diagnosed with any form of locally advanced or metastatic solid tumor for whom there is no 
available standard treatment with proven survival benefit. Based on the nonclinical data in 
Section 4.1.1.1, some indications may have a higher probability of clinical benefit with TAK-931: 
high-grade serous ovarian cancer, uterine carcinosarcoma, squamous esophageal cancer, 
squamous NSCLC, squamous head and neck cancers, rectal adenocarcinoma, and in general 
tumors with known TP53 gene mutations. For any of these preferred indications, patients should 
have exhausted standard therapeutic options with a proven survival benefit.
Toxicity will be evaluated according to NCI CTCAE, version 5.0, effective date 27 November 
2017 [18]. 
Adverse events (AEs) will be assessed and laboratory values, vital signs, and electrocardiograms 
(ECGs) will be obtained to evaluate the safety and tolerability of TAK-931.
Serial blood samples for determination of the plasma concentration of TAK-931 and 
corresponding triplicate ECGs (part 1 only) will be obtained during Cycle 0 at prespecified time 
points as described in the schedule of events (SOE) (Appendix A) and in Section 9.4.

Number of Patients
A total of approximately 44 patients will be enrolled in this study (approximately 20 patients to 
obtain 14 to 16 evaluable patients in part 1 and approximately 24 patients to obtain 14 to 16 
evaluable patients in part 2 [see Section 13.1.1 for definition of evaluable]). These patients will be 
enrolled at approximately 3-4 study centers in the Netherlands. Enrollment is defined as signing of 
the informed consent form (ICF). 
Patients are considered PK evaluable if they complete the protocol-specified dosing and PK 
assessments in Cycle 0 (see Section 13.1.1). Patients may be replaced if they are not evaluable for 
PK. Specifically, patients will not be considered evaluable if 1 of the following occurs during 
Cycle 0:

Duration of Study
6.3.1
Duration of an Individual Patient’s Study Participation
Patients may receive TAK-931 until they experience progressive disease (PD) or unacceptable 
toxicity or until any other discontinuation criterion is met (see Section 8.3.3). The maximum 
scheduled duration of treatment will be 1 year; however, patients receiving clinical benefit (per the 
investigator and as agreed by the sponsor’s medical monitor) can continue on treatment beyond 
1 year with the explicit approval of the sponsor’s medical monitor. 
All patients will attend an end-of-treatment (EOT) visit 30 days (+10 days) after receiving their 
last dose of study drug or before the start of subsequent systemic anticancer therapy, whichever 
occurs first, to permit detection of any delayed TEAEs and resolution of ongoing events. Patients 
with unresolved TEAEs will continue the periodic safety follow-up until complete resolution or 
stabilization (established as squealae) occurs. Patients who discontinue study treatment for reasons 
other than PD will continue PFS follow-up every 12±1 weeks from the EOT visit until the 
occurrence of PD, loss to follow-up, consent withdrawal, death, the start of subsequent systemic 
antineoplastic therapy, or study termination (Section 9.7). 
6.3.2
End of Study/Study Completion Definition and Planned Reporting
Patients will be followed for safety for approximately 30 days after their last dose of study drug or 
until the start of subsequent anticancer therapy, whichever occurs first. All patients will be 
followed for PFS. It is anticipated that this study will last for approximately 24 months. 
6.3.3
Time Frames for Primary and Secondary Endpoints to Support Disclosures
The final data cutoff for the clinical study report will be conducted after all patients have been 
discontinued treatment or transferred to a long-term safety study, a single-patient investigational 
new drug application, or a similar program.

Study Drug Administration
All protocol-specific criteria for administration of study drug must be met and documented before 
drug administration. Study drug will be administered only to eligible patients under the 
supervision of the investigator or identified subinvestigator(s).
8.1.1
Day 1 and Day 3 of Cycle 0, Part 1 Relative Bioavailability Assessment
TAK-931 will be administered to patients on an empty stomach except water from 2 hours before 
taking the study drug until completion of collection of the 4-hour ECG/PK samples on Day 1 and 
Day 3 of Cycle 0. Each dose of the study drug will be given orally with at least 8 ounces (230 mL) 
of water. Accordingly, patients will be instructed to eat a meal or snack at least 2 hours before 
dosing, and to eat a meal or snack after the 4-hour triplicate ECG and blood sample for PK analysis 
are collected. 
8.1.2
Day 1 and Day 3 of Cycle 0, Part 2 Food Effect Assessment
For the fasted treatment, the Day 1 or Day 3 dose of TAK-931 will be administered with 240 mL 
(8 fluid ounces) of water following an overnight fast, including no medications, of approximately 
10 hours. In addition, no food will be allowed for 2 hours after the Day 1 or Day 3 dose. Water is 
allowed as desired except for 1 hour before and after TAK-931 administration. For the fed 
treatment, following an overnight fast (including no medications) of approximately 10 hours, 
patients will start the recommended meal 30 minutes before administration of the Day 1 or Day 3 
dose. Table 8.a shows the approximate composition of a high-fat breakfast. Patients should finish 
the entire meal in 30 minutes or less; TAK-931 will be administered 30 minutes after start of the 
meal with 240 mL (8 fluid ounces) of water. No food will be allowed for at least 2 hours postdose. 
Water is allowed as desired except for 1 hour before and 1 hour after TAK-931 administration. 
Patients will be randomized to receive a standard high-fat meal before dosing on Day 1 or Day 3 of 
Cycle 0.

TAK-931 will be administered to patients with esomeprazole on an empty stomach except water 
from 2 hours before and 2 hours after taking the study drug. Each dose of the study drug will be 
given orally with at least 8 ounces (230 mL) of water. 
8.1.4
TAK-931 Multiple-Dose Administration in Cycle 0 and Beyond
Patients should be instructed to take their study medication at approximately the same time each 
day and not to take more than the prescribed dose at any time. Patients should swallow the study 
medication whole and not chew it, open it, or manipulate it in any way before swallowing. If a 
patient fails to take the TAK-931 dose within the time frame specified (±12 hours), that dose 
should be skipped. Patients should record any skipped doses in their dosing diary (see the study 
manual) and resume dosing at the next scheduled time with the prescribed dosage.
If severe emesis or mucositis prevents the patient from taking a TAK-931 dose, that dose will be 
skipped. If emesis occurs after study medication ingestion and if whole capsule(s) or tablets are 
visible in the vomitus, replacement capsule(s) or tablets should be taken; otherwise the dose will 
not be readministered, and patients should simply adhere to the dosing schedule and resume dosing 
at the next scheduled time with the prescribed dosage. Patients should record the time of the 
emesis in their dosing diary (see Study Manual). Except for the case of emesis with visible 
capsules in the vomitus as described above, patients should never repeat a dose or double-up on 
doses.
Beginning with Cycle 1 and after, TAK-931 will be administered only during Days 1 to 14 of each 
21-day cycle of study participation. TAK-931 doses missed due to any reason, including treatment 
interruption due to toxicity, will not be made up by extending the 14-day treatment period during 
the 21-day cycle. Patients in part 1 will receive 50 mg PIC. Patients in part 2 will receive the tablet 
formulation at a dose that produces comparable exposure to 50 mg PIC as determined in part 1.
8.2
Reference/Control Therapy
No reference or control therapy will be used. Esomeprazole will be used in Cycle 0 of part 2 to 
assess the effects of modifying gastric pH on the PK of TAK-931. 
8.3
Dose Modification Guidelines
Dose modification guidelines for toxicities, based on the type and severity of AEs and causality 
determination by investigators, are described below for TAK-931. Further clarification can be 
obtained in consultation with the sponsor clinician (or designee). In general it is recommended to 
reduce the dose of TAK-931 in 10-mg increments (for example from 50 mg to 40 mg). Reductions 
below 30 mg (PIC or tablets) are not recommended unless the investigator believes that the patient 
is deriving benefit from treatment.

8.3.1
Criteria for Beginning or Delaying a Subsequent Treatment Cycle
Before starting a new treatment cycle, TAK-931–related AEs or laboratory abnormalities must 
have returned to Grade ≤1 or baseline levels or to a level considered acceptable by the physician 
(eg, hypophosphatemia that can be managed by oral replacement).
If there is a delay of a subsequent cycle longer than 2 weeks because of an AE, the patient may be 
withdrawn from treatment unless the patient is receiving clinical benefit as assessed by the 
investigator, with agreement by the sponsor’s medical monitor. TAK-931 dosing may be 
continued at a reduced dose level.
For Cycle 1 onward, treatment with TAK-931 will use a cycle length of 21 days. For a new cycle 
of treatment to begin, the patient must meet the following criteria:

ANC must be ≥1.5 × 109/L.

Platelet count must be ≥75.0 × 109/L.
If the patient fails to meet the above-cited criteria for retreatment, initiation of the next cycle of 
treatment should be delayed until the criteria for re-treatment have been met. The patient has to be 
re-tested or re-evaluated at least once a week at the investigator's discretion. The patient can be 
re-treated once recovery is achieved. 
8.3.2
Criteria for Dose Interruption During a Cycle
All toxicities that occur during the study will be actively managed following the standard of care 
unless otherwise specified in the protocol. Patients experiencing AEs attributed to TAK-931 may 
continue study treatment with the same dose, may have TAK-931 treatment held, may have their 
dose reduced, or may be permanently discontinued from the study. Patients who have study drug 
held because of treatment-related or possibly related AEs may resume study drug treatment after 
resolution of the AE at the same dose level or at a reduced dose depending on the nature and 
severity of the AE and whether it is the first or a subsequent occurrence.
Refer to Table 8.b for general dose modification recommendations. When the dose of TAK-931 is 
withheld according to these criteria, clinical and laboratory reevaluation should be repeated at least 
weekly or more frequently, depending on the nature of the toxicity observed until the toxicity 
resolves to Grade ≤1 or baseline. For transient laboratory abnormalities that, per investigator 
assessment, are not clinically significant or drug-related, continuation of therapy without dose 
modification is permissible upon discussion with the sponsor. See details for the management of 
specific TEAEs in Section 8.7.

Table 8.b
Dose Modification Recommendations for TAK-931 Toxicities
Criteria
Action
Grade 1 AEs
No dose reductions or interruptions 
Grade 2 AEs
Treat according to local practice. Whether to hold treatment or to continue treatment 
at the same or at a reduced dose is at the discretion of the investigator.
Patients experiencing Grade 2 AEs considered related to study treatment that are not 
easily managed or corrected and are not tolerable to the patient, or AEs that are not 
acceptable in the investigator’s judgment, should have study treatment interrupted 
until the AE resolves to Grade ≤1 or baseline and then restarted at the same dose or, 
depending on the toxicity, at a reduced dose level. 
Grade 3 and Grade 4 
non–life-threatening AEs
Hold TAK-931 until resolution to Grade ≤1 or baseline, then resume treatment at 
either the same dose or a reduced dose level at the discretion of the investigator and 
after discussion with the sponsor.
Grade 4 life-threatening AEs
Consider permanently withdrawing the patient from the study, except when the 
investigator determines that the patient is receiving clinical benefit and has 
discussed this with the sponsor; then treatment may be restarted at a reduced dose 
level or below when toxicity recovers to Grade ≤1 or baseline.
AEs of all grades
If treatment has been held for >14 consecutive days without resolution of the 
toxicity (to baseline or Grade ≤1), consider permanently discontinuing study 
treatment unless the patient is receiving clinical benefit for the patient as assessed 
by the investigator and with sponsor's approval. Treatment can be resumed at a 
reduced dose level after resolution of AEs to Grade ≤1 or baseline.
Abbreviation: AE, adverse event. 
If initial dose adjustment does not provide sufficient relief, the dose of TAK-931 can be further 
reduced by an additional dose level if the treating physician believes that the patient is receiving 
clinical benefit. In general, after a dose is reduced it should not be re-escalated even if there is 
minimal or no toxicity with the reduced dose. However, if further evaluation reveals that the AE 
that led to the dose reduction was not study drug-related, the dose may be re-escalated to the 
original dose level. Up to 2 dose level reductions of TAK-931 due to AE are generally 
recommended. If a third dose reduction is needed, it must first be discussed with and approved by 
the sponsor’s medical monitor. 
8.3.3
Criteria for Discontinuation of TAK-931
TAK-931 should be discontinued for patients experiencing an AE for which the investigator 
considers that retreatment of the patient could be dangerous. For Grade 4 life-threatening TEAEs, 
consider permanently withdrawing the patient from the study, except when the investigator 
determines that the patient is receiving clinical benefit and has discussed this with the sponsor, 
then treatment may be restarted at a reduced dose level when toxicity recovers to Grade ≤1 or 
baseline.
If more than 2 dose reductions are required, or if the next cycle of TAK-931 is delayed for 
>14 days because of TAK-931–related toxicities, study treatment should be discontinued unless 
the investigator believes that the patient will benefit from continuing in the study. Further dose 
reduction must be discussed with and approved by the sponsor’s medical monitor. If treatment

discontinuation is determined, the EOT visit should be completed within 30 to 40 days after the 
last administration of TAK-931 or before initiation of new anti-cancer therapy (whichever occurs 
first). 
8.4
Excluded Concomitant Medications and Procedures
All prescription and over-the-counter (OTC) medications, including influenza vaccines, taken by a 
patient since signing the ICF through the EOT visit or before initiation of new anti-cancer therapy 
(whichever occurs first) will be recorded in the designated electronic case report forms (eCRFs). 
Patients must be instructed not to take any medications, including OTC medications and herbal 
supplements, without first consulting with the investigator.
The following medications and procedures are prohibited during the study:

Patients currently on chronic erythropoietin support for anemia may continue to receive 
erythropoietin, but initiation of new erythropoietin therapy is not allowed during Cycle 0 [20]. 

Any investigational agent other than TAK-931.

Any concurrent antineoplastic therapy (eg, chemotherapy, hormonal therapy, immunotherapy, 
radiation therapy except for palliative radiation therapy and once PD is ruled out), or standard 
or investigational agents for treatment of cancer. 

Clinically significant CYP enzyme inducers, such as phenytoin, carbamazepine, enzalutamide, 
mitotane, ritonavir, rifampin, or St John's wort, within 14 days before the first dose of 
TAK-931 and during the study.

Chronic concomitant administration of any PPI is not allowed during the study except for the 
esomeprazole indicated in Cycle 0 of part 2. Patients receiving PPI therapy must stop using the 
PPI for 5 days before their first dose of TAK-931. Examples of PPIs include omeprazole, 
esomeprazole, pantoprazole, lansoprazole, vonoprazan, and rabeprazole. During study 
participation, patients who develop new clinical symptoms that require treatment with PPIs 
should be discussed with the sponsor to determine the dose, schedule, and suitability of the 
patient for continued study participation. 

H2 receptor antagonists (eg, cimetidine, nizatidine, and ranitidine) are not permitted from the 
day before the first dose (Day -1) through the last day of TAK-931 dosing in the treatment 
cycle. Intermittent use may be considered especially during the 1-week rest period if needed. 
Patients who require additional therapy with H2 receptor antagonists during the active 
treatment period with TAK-931 should be discussed with the sponsor to determine the dose, 
schedule, and suitability of the patient for continued study participation. During Cycle 0 in 
part 2, OTC antacid preparations such as calcium carbonate are not allowed.
8.5
Permitted Concomitant Medications and Procedures
Other medications considered necessary for the safety and wellbeing of the patient may be 
administered at the discretion of the investigator. Any concomitant medications added or 
discontinued during the study should be recorded in the eCRF. Use of myeloid growth factors (eg,

granulocyte colony-stimulating factor [G-CSF], granulocyte-macrophage colony-stimulating 
factor) may be administered to manage patients who experience severe and/or febrile neutropenia 
if clinically indicated in accordance with the American Society of Clinical Oncology (ASCO) 
guidelines and/or institutional practices. For the first episode of neutropenia, dose reduction is 
preferred [21]. 
During Cycle 0 in part 1 and from Cycle 1 and after in both parts, OTC antacid preparations are 
allowed but should not be taken from 2 hours before and until 2 hours after administration of 
TAK-931. They are allowed as needed on non-dosing days. 
8.6
Precautions and Restrictions
Patients must be educated about adequate and safe storage of TAK-931 at home. They must be 
informed about safe self-administration of the drug following the directions given in Section 8.1. 
and Section 8.12. 
Because of the risk of neutropenia, patients should be instructed to measure axillary temperature at 
least daily and to follow local procedures if their body temperature reaches 38ºC or above. 
8.6.1
Pregnancy and Contraception
It is not known what effects TAK-931 has on human pregnancy or development of the embryo or 
fetus; therefore, female patients participating in this study should avoid becoming pregnant, and 
male patients should avoid impregnating a female partner. Nonsterilized female patients of 
reproductive age and male patients should use effective methods of contraception throughout 
defined periods during and after study treatment as specified below. 
Female patients must meet 1 of the following:

Postmenopausal for at least 1 year before the screening visit, OR

Surgically sterile, OR

If they are of childbearing potential, agree to practice 1 highly effective method of 
contraception and 1 additional effective (barrier) method at the same time, from the time of 
signing of the ICF through 30 days after the last dose of study drug, OR

Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of 
the patient. (Periodic abstinence [eg, calendar, ovulation, symptothermal, postovulation 
methods], withdrawal, spermicides only, and lactational amenorrhea are not acceptable 
methods of contraception. Female and male condoms should not be used together.)
Male patients, even if surgically sterilized (eg, status postvasectomy) must agree to 1 of the 
following:

Agree to practice effective barrier contraception during the entire study treatment period and 
through 120 days after the last dose of study drug, OR

Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of 
the patient. (Periodic abstinence [eg, calendar, ovulation, symptothermal, postovulation

not acceptable methods of contraception. Female and male condoms should not be used 
together.) AND

Agree not to donate sperm during the study and for 120 days after receiving their last dose of 
study drug.
8.6.2
Females Who are Lactating or Breastfeeding
Female patients who are lactating must refrain from breastfeeding from the start of study 
participation (Section 7.2, exclusion criterion #1) through 30 days after the last dose of study drug.
8.6.3
Patients With Prior Exposure to Hepatitis B or Hepatitis C
Patients who have detectable HBV or HCV viral loads are excluded from study participation (see 
Section 7.2, exclusion criterion #8). Patients with prior exposure to HBV or HCV who have 
subsequently cleared the infection (based on a negative viral load) are allowed on study, but should 
be monitored for re-activation every 2 months. Patients who develop detectable HBV or HCV in 
their blood will have TAK-931 treatment held, with administration of a nucleoside antagonist per 
institutional guidelines, and consultation with a hepatologist should be considered. 
Restarting TAK-931 after HBV or HCV is no longer detected may be considered in the setting of 
continued nucleoside antagonist prophylaxis and after a discussion with the Takeda medical 
monitor to review the potential benefit versus risk to the patient in the setting of a controlled HBV 
or HCV infection. 
8.6.4
Photosafety
In the photoabsorption spectrum, TAK-931 exhibits a peak at 294 nm, which is within the zone of 
concern for potential phototoxicity and/or photoallergy. A photosafety assessment of TAK-931 
has not yet been performed; therefore, patients should be cautioned to take protective measures 
(eg, avoidance of exposure to direct sunlight, use of sunglasses and long sleeves).
8.7
Management of Specific AE
Therapies that are required to manage AEs and control cancer symptoms are allowed per standard 
clinical practice, unless specifically excluded. Supportive care agents, such as erythropoietin and 
G-CSF are permitted as needed per the ASCO [20,21] guidelines. Blood products (red blood cell 
[RBC] and platelet transfusions), and pain medications are permitted per local institutional 
practice. Each treatment intervention should be clearly documented.
8.7.1
Hematologic Toxicities
Refer to Table 8.c for dose delay and reduction recommendations for hematologic toxicities. 
Dosing with TAK-931 should be held if significant treatment-emergent cytopenia or bleeding is 
suspected to be related to, or can be worsened by, study treatment. Precautionary measures should 
be taken to prevent bleeding and overwhelming infections. Blood transfusions (RBC or platelet) 
and hematopoietic or thrombopoietic stimulating factors may be used to treat cytopenia/

GI AEs
Nausea and/or Vomiting
This study will not initially employ prophylactic antiemetics; however, a patient who develops 
nausea and/or vomiting will be actively managed by employing optimal antiemetic treatment per 
local standard practice. Additionally, antiemetics could be used prophylactically as clinically 
indicated following the occurrence of the first event of TAK-931–related or possibly related 
nausea and/or vomiting. An optimal antiemetic regimen is defined as one that employs both a 
5-hydroxytryptamine 3 serotonin antagonist and a corticosteroid given in standard doses and 
according to standard schedules. PPIs and H2 receptor antagonists are not allowed during 
treatment.

Diarrhea
Prophylactic antidiarrheals will not be used in this study; however, diarrhea should be managed 
according to clinical practice, including the administration of antidiarrheals once infectious causes 
are excluded. Fluid intake should be maintained to avoid dehydration. Fluid deficit should be 
corrected before initiation of treatment and during treatment.
8.7.3
Hepatobiliary Disorders
Liver function tests should be monitored throughout participation in the study (AST, ALT, 
alkaline phosphatase, and bilirubin). If abnormalities are observed, the patient should be assessed 
for causes other than TAK-931. Transaminase elevations should be managed according to locally 
accepted clinical practice, including frequent monitoring of appropriate laboratory functions 
(2-3 times per week). If possible, hepatotoxic concomitant medications should be discontinued in 
patients who develop elevated transaminases.
Dose interruption should be considered in any patient who develops Grade 2 elevated 
transaminases lasting longer than 2 weeks or any time a patient develops Grade ≥3 elevated 
transaminases. Treatment should be restarted at a reduced dose level (after transaminase levels 
resolve to Grade ≤1 or baseline), provided that this occurs within 14 days of dose interruption.
Patients who develop AST or ALT >3 times the ULN in conjunction with bilirubin >1.5 times the 
ULN must be permanently discontinued from study treatment, unless a correctable non–
drug-related cause of hepatic injury is identified. 
8.7.4
Cardiac Toxicities
A MUGA scan or ECHO will be performed as indicated in the SOE. ECHO or MUGA scan will 
also be performed if symptoms of heart failure are noted. Patients with significant abnormalities 
should be treated per standard of care at their institution and the treatment should be documented 
in the eCRFs. If Grade ≥2 decrease in cardiac ejection fraction occurs, treatment should be 
discontinued until resolution to Grade ≤1, then the study drug will be resumed at a reduced dose 
level. 
If Grade 3 QT interval corrected for heart rate (QTc) prolongation or arrhythmia occur, treatment 
should be discontinued until resolution to Grade ≤1. An evaluation by a cardiologist must be 
performed and adequate patient management and follow-up (including hospitalization if 
necessary) should be put in place immediately after observation of a QTc prolongation or 
arrhythmia. Review of concomitant medications and electrolyte abnormalities for QT effects is 
also required. Upon resolution of the event to Grade ≤1, the study drug will be resumed at a 
reduced dose level. For Grade 4 QTc prolongation or arrhythmia, treatment should be permanently 
discontinued. If the patient shows a clinically significant benefit and is willing to resume 
treatment, treatment can be resumed at a reduced dose level after consultation with a cardiologist
and approval from the sponsor (see Section 8.3.3).

Hypotension
Transient hypotension with reflex tachycardia was observed in toxicology studies with dogs at 
tmax. This risk has not been substantiated in Japanese patients dosed up to 80 mg in the FIH study.
If a hypotensive event occurs, the patient should be advised to contact the site for instructions. BP 
and HR monitoring should be performed at home, if indicated by the investigator, and values 
recorded in the patient’s diary. 
If a hypotensive event occurs at the site, the patient can be discharged only if no clinically relevant 
BP or HR changes occurred during the observation period. If the investigator notes changes in 
BP/HR and/or symptoms of concern, subsequent doses of TAK-931 should be administered at the 
site with the same monitoring as for Days 1 and 3 of Cycle 0 until the risk is confirmed or 
discharged. 

Grade 1 hypotension: hypotension (at least 20 mmHg systolic BP drop and/or at least 
10 mmHg diastolic BP drop vs individual patient’s baseline BP) without symptoms and no 
reflex tachycardia at rest. No treatment modification or monitoring is indicated. 

Grade 2 hypotension: hypotension with compatible symptoms and/or reflex tachycardia (or 
Grade 2 presyncope). BP, HR, ECG, and blood draw for TAK-931 concentration will be 
performed promptly. Repeated assessments should be performed as clinically indicated. 
Treatment should follow local practice. After recovery and normalization to baseline, the 
patient can continue receiving treatment at the same dose if it is the first occurrence or at a 
reduced dose if it is a reoccurrence. 

Grade ≥3 hypotension: Stop treatment. Treatment for the event should follow local practice. 
Consider continuous electronic monitoring of HR, BP, and ECG until complete normalization 
of vital signs. Take a blood sample for measurement of TAK-931 concentration. Depending on 
the seriousness of the event, associated pathologies, and recovery, consider either 
discontinuing the patient’s treatment or continuing treatment at a reduced dose level.

A drug dispensing log, including records of drug received from the sponsor and drug dispensed to 
the patients, will be provided and kept at the study site. Storage area temperature conditions must 
be monitored and recorded daily. A daily temperature log will also be kept at the study site.
Because TAK-931 is an investigational agent, it should be handled with due care. If contact with a 
broken capsules occurs, raising dust should be avoided during the clean-up operation. The product 
may be harmful if inhaled, ingested, or absorbed through the skin. Gloves and protective clothing 
should be worn during the clean-up operation. The area should be ventilated and the spill site 
washed after material cleanup is complete. The spilled material should be disposed of as hazardous 
medical waste in compliance with federal, state, and local regulations. If contact with the powder 
(eg, from a broken capsule) occurs, skin should be washed immediately with soap and copious 
amounts of water for at least 15 minutes. If contact with the eyes occurs, copious amounts of water 
should be used to flush the eyes for at least 15 minutes. Medical personnel should be notified. 
Patients will receive instructions for home storage and administration of TAK-931. 
Patients will be instructed to return any unused study drug in the original packaging along with 
their completed diary cards at the appropriate visits.
Please refer to the study manual for additional instructions.
8.12.2 Esomeprazole
The container should be stored at the investigative site at controlled room temperature (25°C; 
excursions permitted from 15°C to 30°C) and used before the expiration date indicated on the label

9.3.1
Part 1
Patients will be randomly assigned in a 1:1 ratio with a block size of 2 to receive a single dose of 
TAK-931 either as PIC or tablet on Day 1 of Cycle 0. These patients will then be administered in 
the alternate formulation on Day 3 of Cycle 0. Details of treatments are in Section 6.1.1.
9.3.2
Part 2
Patients will be randomly assigned in a 1:1 ratio with a block size of 2 to receive a single dose of 
TAK-931 with or without a standard high-fat breakfast (see Section 8.1.2) on Day 1 of Cycle 0. 
These patients will then be administered in the alternate food intake condition on Day 3 of Cycle 0. 
Details of treatments are in Section 6.1.2. 
9.4
Study Procedures
Refer to the SOE (Appendix A) for timing of assessments. Additional details are provided as 
necessary in the sections that follow. Evaluations during the screening period are to be conducted 
within 28 days before administration of the first dose of study drug. Unless otherwise noted, 
evaluations during the treatment period must occur before study drug administration. Tests and 
procedures should be performed on schedule for all visits. The timing of PK assessments is 
specified in Appendix A, Tables 1, 2, and 4. All EOT evaluations should occur 30 to 40 days after

Refer to the SOE (Appendix A) for timing of assessments. Additional details are provided as 
necessary in the sections that follow.
9.4.1
Informed Consent
Each patient must provide written informed consent before any study-required procedures are 
conducted, unless those procedures are performed as part of the patient’s standard care.
9.4.2
Patient Demographics
The date of birth, race, ethnicity, and sex of the patient are to be recorded during screening.
9.4.3
Medical History
During the screening period, a complete medical history will be compiled for each patient. The 
history will emphasize the background and progress of the patient’s malignancy and include a 
description of prior therapies, with a breakdown by treatment intention (neoadjuvant, adjuvant, or 
metastatic); line of therapy for metastatic disease, regimen, and drug(s); treatment start and stop 
dates (including at least month and year); best response; and PD date. Known genetic and serum 
tumor biomarkers previously analyzed at the site should be recorded. In addition, concomitant 
medications will be recorded as specified in Section 9.4.8.
9.4.4
Physical Examination
A physical examination will be completed per standard of care at the times specified in the SOE 
(Appendix A). Any clinically relevant findings are to be documented. 
9.4.5
Patient Height and Weight
Height and weight will be measured only once during screening (within 28 days before the first 
dose of TAK-931). 
9.4.6
Vital Signs
Standard vital signs should be obtained at least once during each visit specified in the SOE 
(Appendix A) and will include temperature (may be oral or axillary temperature), BP, and HR. 
9.4.7
Pregnancy Test
A serum pregnancy test will be performed for women of childbearing potential at screening and 
again at Cycle 0 Day 1 if the screening test was performed more than 4 days before the first dose of 
study drug. 
Women of childbearing potential will be defined as sexually mature females who meet the 
following criteria:

Those who have not undergone hysterectomy or bilateral oophorectomy, AND


Those who have not had natural menopause for 12 consecutive months or longer (eg, 
follicle-stimulating hormone >40 IU/L and no menopausal period for at least 12 consecutive 
months). Note that a loss of menopausal periods following chemotherapy may not rule out 
childbearing potential. 
The results from these tests must be available and negative before the first dose of study drug is 
administered. If Cycle 0, Day 1 serum pregnancy results will not be available before dosing, a 
urine pregnancy test may be performed. 
Pregnancy tests may also be repeated during the study at the discretion of the investigator, if 
requested by an IEC/IRB, or if required by local regulations.
9.4.8
Concomitant Medications and Procedures
Medications used by the patient and therapeutic procedures completed by the patient will be 
recorded in the eCRF from the ICF signature through the EOT visit or before initiation of new 
anti-cancer therapy, whichever occurs first. See Sections 8.4 and 8.5 for a list of medications and 
therapies that are prohibited or allowed during the study.
9.4.9
AEs
Monitoring of AEs, serious and nonserious, will be conducted throughout the study as specified in 
the SOE (Appendix A). Refer to Section 10.0 for details regarding definitions, documentation, and 
reporting of pretreatment events (PTEs), AEs, and SAEs.
9.4.10
Enrollment
Enrollment is defined as the randomization date. Procedures for completing the enrollment 
information are described in the study manual. Information regarding patients who do not meet the 
study entry criteria will be collected in a separate log. 
9.4.11
ECG
9.4.11.1 Safety ECGs
Standard 12-lead ECGs will be performed at the time points specified in the SOE (Appendix A). 
All machine-generated tracings should be acquired in the supine position after patients have been 
resting for 5 minutes. A qualified person will interpret the ECGs locally. Additional ECGs may be 
obtained as clinically indicated at the discretion of the investigator (see Section 8.7.5). 
9.4.11.2 Triplicate ECGs
Time-matched triplicate ECGs and PK samples will be collected during Cycle 0 on Days 1 and 3 
of part 1 (Appendix A, Table 4). Triplicate ECGs will be recorded electronically and transmitted to 
a central vendor for storage.

Before each nominal triplicate ECG sampling time point, patients must maintain a supine position 
for 15 minutes. Each ECG recording of the triplicate ECGs should occur within 3 minutes of the 
previous recording and over a 10-minute window.
For these matched PK/triplicate ECG collections, the PK blood sample should be collected only 
after completion of the triplicate ECG collection. It is recommended that patients refrain from 
eating or limit themselves to bland food for 2 hours before and until completion of the 4-hour 
triplicate ECG measurements. The PK blood draws will occur immediately following the 
completion of the triplicate ECG extractions on Days 1 and 3 of Cycle 0.

Patients will undergo CT scan, with contrast as appropriate (areas of known or clinically suspected 
disease), or MRI scan to monitor and assess PD, using RECIST, version 1.1 [19] as outlined in the 
SOE (Appendix A). Brain CT scan evaluation at screening is not required in the absence of 
symptoms.
Primary determination of disease status will be based on local investigator assessment. The 
collection and central storage of scans are planned in case more detailed analysis of imaging data, 
as determined by the sponsor, is needed. 
Tests will be repeated at the frequency specified in the SOE.

Study Compliance
Study drug will be administered or dispensed only to eligible patients under the supervision of the 
investigator or identified subinvestigator(s). The appropriate study personnel will maintain records 
of study drug receipt and dispensing.
Patients are responsible for taking and storing TAK-931 at home as instructed by site personnel 
and will receive a sufficient quantity of study drug for 1 cycle of treatment. Patients will be given a 
diary to record study drug dosing and associated events (time of intake, doses missed, vomiting,

symptoms, etc). The study center staff will check the patient’s drug diary versus the patient’s 
supply of TAK-931 to assess compliance.
Tests and procedures should be performed on schedule; however, unless otherwise specified, 
occasional changes are allowable within a 2-day window for holidays, vacations, and other 
administrative reasons. 
9.10
Posttreatment Follow-up Assessments (PFS)
The EOT visit for all patients will take place 30 to 40 days after the last dose. 
Patients who stop treatment for any reason other than progressive disease (or clinical deterioration) 
will continue to have PFS follow-up visits. PFS follow-up visits should be conducted at the site 
every 12 weeks from the EOT visit until the occurrence of death, PD, start of a new systemic 
anticancer treatment, consent withdraw, or loss to follow up, whichever occurs first.
The end-of-study visit is to be completed when the patient discontinues from the follow-up period. 
See the SOE for appropriate assessments during follow-up.
NOTE: Related SAEs must be reported to the Takeda Global Pharmacovigilance department or 
designee. This includes deaths that the investigator considers related to study drug that occur 
during posttreatment follow-up. Refer to Section 10.0 for details regarding definitions, 
documentation, and reporting of SAEs.

ADVERSE EVENTS
10.1
Definitions
10.1.1 PTE Definition
A PTE is any untoward medical occurrence in a patient or subject who has signed informed 
consent to participate in a study but before administration of any study medication; it does not 
necessarily have to have a causal relationship with study participation.
10.1.2 AE Definition
AE means any untoward medical occurrence in a patient or subject administered a pharmaceutical 
product; the untoward medical occurrence does not necessarily have a causal relationship with this 
treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
(investigational) product whether or not it is related to the medicinal product. This includes any 
newly occurring event, or a previous condition that has increased in severity or frequency since the 
administration of study drug.
An abnormal laboratory value will not be assessed as an AE unless that value leads to 
discontinuation or delay in treatment, dose modification, therapeutic intervention, or is considered 
by the investigator to be a clinically significant change from baseline.
10.1.3 SAE Definition
SAE means any untoward medical occurrence that at any dose:

Results in death.

Is life-threatening (refers to an AE in which the patient was at risk of death at the time of the 
event. It does not refer to an event which hypothetically might have caused death if it were 
more severe).

Requires inpatient hospitalization or prolongation of an existing hospitalization (see 
clarification in the paragraph in Section 10.2 on planned hospitalizations).

Results in persistent or significant disability or incapacity. (Disability is defined as a 
substantial disruption of a person’s ability to conduct normal life functions).

Is a congenital anomaly/birth defect.

Is a medically important event. This refers to an AE that may not result in death, be 
immediately life threatening, or require hospitalization, but may be considered serious when, 
based on appropriate medical judgment, may jeopardize the patient, require medical or 
surgical intervention to prevent 1 of the outcomes listed above, or involves suspected 
transmission via a medicinal product of an infectious agent. Examples of such medical events 
include allergic bronchospasm requiring intensive treatment in an emergency room or at home, 
blood dyscrasias or convulsions that do not result in inpatient hospitalization, or the

development of drug dependency or drug abuse; any organism, virus, or infectious particle 
(eg, prion protein transmitting transmissible spongiform encephalopathy), pathogenic or 
nonpathogenic, is considered an infectious agent.
In this study, intensity for each AE, including any lab abnormality, will be determined using the 
NCI CTCAE, version 5.0, effective date 27 November 2017 [18]. Clarification should be made 
between an SAE and an AE that is considered severe in intensity (Grade 3 or 4), because the terms 
serious and severe are not synonymous. The general term severe is often used to describe the 
intensity (severity) of a specific event; the event itself, however, may be of relatively minor 
medical significance (such as a Grade 3 headache). This is not the same as serious, which is based 
on patient/event outcome or action criteria described above, and is usually associated with events 
that pose a threat to a patient’s life or ability to function. A severe AE (Grade 3 or 4) does not 
necessarily need to be considered serious. For example, a WBC count of 1000/mm3 to less than 
2000 is considered Grade 3 (severe) but may not be considered serious. Seriousness (not intensity) 
serves as a guide for defining regulatory reporting obligations.
10.2
Procedures for Recording and Reporting AEs and SAEs
All AEs spontaneously reported by the patient or in response to an open question from study 
personnel or revealed by observation, physical examination, or other diagnostic procedures will be 
recorded on the appropriate page of the eCRF (see Section 10.3 for the period of observation). Any 
clinically relevant deterioration in laboratory assessments or other clinical finding is considered an 
AE. When possible, signs and symptoms indicating a common underlying pathology should be 
noted as a single comprehensive event.
Regardless of causality, SAEs must be reported (see Section 10.3 for the period of observation) by 
the investigator to the Takeda Global Pharmacovigilance department or designee within 24 hours 
of becoming aware of the event. This will be done by transmitting an electronic data capture 
(EDC) SAE report. If transmission of an EDC SAE report is not feasible, then a facsimile of the 
completed Takeda paper-based SAE form will be sent. A sample of the paper-based SAE form and 
processing directions are in the study manual. Information in the SAE report or form must be 
consistent with the data provided on the eCRF.
If information not available at the time of the first report becomes available at a later date, then the 
investigator will transmit a follow-up EDC SAE report (or a paper-based SAE form if an EDC 
SAE report is not feasible) or provide other documentation 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.
Planned hospital admissions or surgical procedures for an illness or disease that existed before the 
patient was enrolled in the study are not to be considered AEs unless the condition deteriorated in 
an unexpected manner during the study; eg, surgery was performed earlier or later than planned.

Protocol 
21 June 2018
For both serious and nonserious AEs, the investigator must determine both the severity (toxicity 
grade) of the event and the relationship of the event to study drug administration. 
Severity (toxicity grade) for each AE, including any laboratory abnormality, will be determined 
using the NCI CTCAE, version 5.0, effective 27 November 2017 [18]. The criteria are provided in 
the study manual.
Relationship of the event to study drug administration (ie, its causality) will be determined by the 
investigator responding yes (related) or no (unrelated) to this question: Is there a reasonable 
possibility that the AE is associated with the study drug?
10.3
Monitoring of AEs and Period of Observation
AEs, both nonserious and serious, will be monitored throughout the study as follows: 

AEs
–
AEs will be reported from the signing of informed consent through 30 days after 
administration of the last dose of study drug and recorded in the eCRFs. 

SAEs
–
Serious PTEs will be reported to the Takeda Global Pharmacovigilance department or 
designee from the time of the signing of the ICF up to first dose of study drug, and will also 
be recorded in the eCRF. 
–
Related and unrelated treatment-emergent SAEs will be reported to the Takeda Global 
Pharmacovigilance department or designee from the first dose of study drug through 
30 days after administration of the last dose of study drug and recorded in the eCRF. After 
this period, only related SAEs must be reported to the Takeda Global Pharmacovigilance 
department or designee. SAEs should be monitored until they are resolved or are clearly 
determined to be due to a patient’s stable or chronic condition or intercurrent illness(es).
10.4
Procedures for Reporting Drug Exposure During Pregnancy and Birth Events
If a woman becomes pregnant or suspects that she is pregnant while participating in this study, she 
must inform the investigator immediately and permanently discontinue study drug. The sponsor 
must also be contacted immediately by faxing a completed Pregnancy Form to the Takeda Global 
Pharmacovigilance department or designee (see Section 10.2). The pregnancy must be followed 
for the final pregnancy outcome.
If a female partner of a male patient becomes pregnant during the male patient’s participation in 
this study, the sponsor must also be contacted immediately by faxing a completed pregnancy form 
to the Takeda Global Pharmacovigilance department or designee (see Section 10.2). Every effort 
should be made to follow the pregnancy for the final pregnancy outcome.

Procedures for Reporting Product Complaints or Medication Errors (Including 
Overdose)
A product complaint is a verbal, written, or electronic expression that implies dissatisfaction 
regarding the identity, strength, purity, quality, or stability of a drug product. Individuals who 
identify a potential product complaint situation should immediately report this via the phone 
numbers or e-mail addresses provided below.
A medication error is a preventable event that involves an identifiable patient and that leads to 
inappropriate medication use, which may result in patient harm. Whereas overdoses and 
underdoses constitute medication errors, doses missed inadvertently by a patient do not. 
Individuals who identify a potential medication error (including overdose) situation should 
immediately report this via the phone numbers or e-mail addresses provided below.

Product complaints in and of themselves are not AEs. If a product complaint results in an SAE, an 
SAE form should be completed and sent to Cognizant (refer to Section 10.2). 
10.6
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, including the European 
Medicines Agency, 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 to 
the regulatory authorities as an expedited report 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 product’s administration or in the 
overall conduct of the study. The investigational site also will forward a copy of all expedited 
reports to his or her IRB or IEC in accordance with national regulations.

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.
Any change of, modification of, or addition to the data on the eCRFs should be made by the 
investigator or appropriate site personnel. Corrections to eCRFs 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.
The principal investigator must review the eCRFs for completeness and accuracy and must sign 
and date the appropriate eCRFs as indicated. Furthermore, the principal investigator must retain 
full responsibility for the accuracy and authenticity of all data entered on the eCRFs.
eCRFs 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 eCRFs. The completed eCRFs 
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.
12.2
Record Retention
The investigator agrees to keep the records stipulated in Section 12.1 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 ICFs, subject authorization forms regarding the use of 
personal health information (if separate from the ICFs), electronic copy of eCRFs, including the 
audit trail, and detailed records of drug disposition to enable evaluations or audits from regulatory 
authorities, the sponsor or its designees. Any source 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

STATISTICAL METHODS
13.1
Statistical and Analytical Plans
A statistical analysis plan will be prepared and finalized before database lock. This document will 
provide further details regarding the definition of analysis variables and analysis methodology to 
address all study objectives. 
13.1.1 Populations for Analysis
The populations used for analysis will include the following:

Safety population: The safety population is defined as all patients who receive any amount of 
study drug.

PK population: The PK population is defined as all patients for whom there are sufficient 
dosing and TAK-931 concentration-time data to reliably estimate the PK parameters. This 
population will be used for analyses of PK parameters. Patients who have any of the 
occurrences listed in Section 6.2 during Cycle 0 will not be considered PK-evaluable and may 
be replaced.

Response-evaluable population: The response-evaluable population is defined as patients who 
receive at least 1 dose of study drug, have measurable disease at baseline, and have at least
1 postbaseline response assessment.
13.1.2 Procedures for Handling Missing, Unused, and Spurious Data
All available safety, tolerability, antitumor activity, PK, and pharmacodynamic data will be 
included in data listings and tabulations. No imputation of values for missing data will be 
performed. The relevance of missing sample data will be assessed. 
Data that are potentially spurious or erroneous will be examined according to standard data 
management operating procedures. 
13.1.3 Analysis of Demographics and Other Baseline Characteristics
Demographic (age, sex, and other parameters as appropriate) and baseline disease characteristics 
(weight, height, and other parameters as appropriate) will be summarized.
13.1.4 Antitumor Activity Analysis
Secondary antitumor activity parameters are ORR, PFS, DCR, and DOR. DCR will be assessed 
per RECIST version 1.1 (CR + PR + SD; SD must be ≥1 post baseline CT scan evaluation from 
treatment initiation to qualify for DCR). 
The DCR and ORR will be estimated with 2-sided 95% exact binomial CIs using the 
response-evaluable population (Section 13.1.1). 
PFS is defined as the time from the date of randomization to the date of first documentation of PD 
or death due to any cause, whichever occurs first. The Kaplan-Meier survival curves, 25th, 50th

(median), and 75th percentiles (if estimable), along with their 2-sided 95% CIs and percentage of 
censored observations will be provided. PFS will be analyzed using the safety population. 
DOR is defined as the time from the date of first documentation of a response to the date of first 
documentation of PD. Patients without documentation of PD at the time of analysis will be 
censored at the date of their last response assessment that is SD or better. DOR will be analyzed 
using the Kaplan-Meier method. DOR will be analyzed using the responders in the 
response-evaluable population.
13.1.5 PK Analysis
13.1.5.1 Part 1
For the relative bioavailability assessment, the ratio (tablet to PIC) of geometric mean AUClast, 
AUC∞and Cmax and associated 2-sided 90% CIs will be calculated, based on the within-patient 
variance estimated by analysis of variance. The PK population will be used for the analysis.
13.1.5.2 Part 2
For the food effect assessment, the ratio (fed to fasted) of geometric mean AUClast, AUC∞and Cmax
and associated 2-sided 90% CIs will be calculated, based on the within-patient variance estimated 
by analysis of variance. For evaluating the effect of esomeprazole on TAK-931 PK, the ratio 
(presence of esomeprazole to absence of esomeprazole) of geometric mean AUClast, AUC∞, and 
Cmax and associated 2-sided 90% CIs will be calculated based on the within-patient variance 
estimated by analysis of variance. The PK population will be used for these analyses.
TAK-931 PK parameters will be estimated using noncompartmental methods with WinNonlin 
Phoenix version 6.2 or higher (Pharsight Corp, Mountain View, California). Descriptive statistics 
for TAK-931 plasma concentrations and the following PK parameters will be tabulated by 
formulation (part 1), food intake state (fed or fasted, part 2) and the use of esomeprazole (in the 
presence or absence of esomeprazole, part 2):

Cmax.

CL/F.

tmax.

AUClast. 

AUC∞.

t1/2z.
Individual TAK-931 concentration-time data and individual PK parameters will be presented in 
listings and tabulated using summary statistics. Individual and mean plasma concentration-time 
profiles will be plotted.

13.1.7 Safety Analysis
Safety will be evaluated by the incidence of TEAEs, defined as any AEs that occur after signing 
the ICF through 30 days after the last dose of study drug, severity, and by changes from baseline in 
the patient’s vital signs and clinical laboratory results using the safety population. Exposure to 
study drug will be summarized, and reasons for discontinuation and modification will be tabulated. 
Safety will be summarized by cohort. 
TEAEs will be tabulated according to the MedDRA by System Organ Class, High Level Term, and 
Preferred Term and will include the following categories:
!
TEAEs.
!
Drug-related TEAEs.
!
Grade ≥3 TEAEs.
!
Grade ≥3 drug-related TEAEs.
!
Most common TEAEs (≥10% of all patients).
!
SAEs.
Listings of TEAEs resulting in study drug discontinuation and dose modification will be provided.
Descriptive statistics for the actual values of clinical laboratory parameters (and/or change from 
baseline in clinical laboratory parameters) will be presented for all scheduled measurements over 
time. Mean laboratory values over time will be plotted for key laboratory parameters.
Descriptive statistics for the actual values (and/or the change from baseline) of vital signs, weight, 
ECHO, or MUGA scans over time will be tabulated by scheduled time point.
Shift tables for laboratory parameters and other safety parameters deemed appropriate will be 
generated to show changes in NCI CTCAE grade from baseline to the worst postbaseline value. 
Graphical displays of key safety parameters, such as scatter plots of baseline versus worst 
postbaseline values, may be used to understand the TAK-931 safety profile.
Concomitant medications collected from ICF signature through the study period will be coded 
using the WHO Drug Dictionary. The number and percentage of patients taking concomitant 
medications will be tabulated by WHO drug generic term using the safety population.
Additional safety analyses may be performed to more clearly enumerate rates of toxicities and to 
further define the safety profile of TAK-931.

ECG Analysis
ECG intervals (QT, QTc, and PR), QRS duration, and ventricular rate will be summarized at each 
scheduled time point, along with mean change from baseline to each posttreatment time point. The 
number and percentage of patients with ECG abnormalities will be summarized at each time point. 
Patients will undergo ECGs as specified in the Schedule of Events (Appendix A, Tables 1, 2, and 
4). 
13.2
Determination of Sample Size
The sample size calculation is based on the expected 2-sided 90% CI for the difference in the 
paired, log transformed AUC (or Cmax) means of TAK-931 administered as tablet and PIC 
formulations. On the basis of the preliminary data obtained from Study TAK-931-1002, the 
within-subject %CV was estimated to be 35.0% for AUC and 36.9% for Cmax. Assuming the 
true/assumed AUC (or Cmax) ratio is 1.0, with a sample size of 14 evaluable patients, the 90% CI of 
the ratio of geometric means is expected to be (0.795-1.257) for AUC and (0.786-1.272) for Cmax
on the basis of the previously discussed variance assumptions. If the ratio is X, the 90% CI of the 
ratio of geometric means is expected to be within (0.795X-1.257X) for AUC and (0.786X-1.272X) 
for Cmax. Patients who are not PK-evaluable may be replaced to ensure the availability of 14 to 16 
PK-evaluable patients for the final analysis of part 1 and part 2.

QUALITY CONTROL AND QUALITY ASSURANCE
14.1
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 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 (CRO) and by the IRB or IEC.
All aspects of the study and its documentation will be subject to review by the sponsor or designee 
(as long as blinding is not jeopardized), including but not limited to the Investigator’s Binder, 
study medication, subject medical records, informed consent documentation, documentation of 
subject authorization to use personal health information (if separate from the ICFs), and review of 
eCRFs 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.
14.2
Protocol Deviations
The investigator should not deviate from the protocol, except where necessary to eliminate an 
immediate hazard to study 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.
The site should document all protocol deviations in the subject’s source documents. If a significant 
deviation occurs, the site should notify the sponsor or its designee (and IRB or EC, as required). 
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. A 
protocol deviation form should be completed by the site and signed by the sponsor or designee for 
any significant deviation from the protocol.
14.3
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 United States [US] Food and Drug Administration [FDA], 
the United Kingdom Medicines and Healthcare products Regulatory Agency [MHRA], and the 
Pharmaceuticals and Medical Devices Agency of Japan [PMDA]). If the study site is contacted for 
an inspection by a regulatory body, the sponsor should be notified immediately. The investigator 
and institution guarantee access for quality assurance auditors to all study documents as described 
in Section 14.1.

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 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” listed in Appendix B. The 
principles of Helsinki are addressed through the protocol and through appendices containing 
requirements for informed consent and investigator responsibilities.
15.1
IRB and/or IEC Approval
IRBs and IECs must be constituted according to the applicable 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 US 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 IB, a copy of the ICF, 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, ICF) reviewed; and state the approval date. The sponsor will ship drug the
sponsor has confirmed the adequacy of site regulatory documentation and, when applicable, the 
sponsor has received permission from competent authority to begin the study. Until the site 
receives 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 ICF, recruitment 
materials intended for viewing by subjects, local safety reporting requirements, reports and 
updates regarding the ongoing review of the study at intervals specified by the respective IRB or 
IEC, and submission of the investigator’s final status report to IRB or IEC. All IRB and IEC 
approvals and relevant documentation for these items must be provided to the sponsor or its 
designee.
Subject incentives should not exert undue influence for participation. Payments to subjects must 
be approved by the IRB or IEC and sponsor.

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 ICF, 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 ICF 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 ICF will 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 investigator is responsible for the preparation, content, and IRB or IEC approval of the ICF 
and if applicable, the subject authorization form. The ICF, subject authorization form (if 
applicable), and subject information sheet (if applicable) must be approved by both the IRB or IEC 
and the sponsor before use.
The ICF, 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 ICF, 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 ICF 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 before the 
subject enters 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 ICF and subject authorization (if applicable) at the time of 
consent and before 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 ICFs 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 ICF.
15.3
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, US 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, subject name, address, and other identifier fields 
not collected on the subject’s CRF).
15.4
Publication, Disclosure, and Clinical Study Registration Policy
15.4.1 Publication 
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. If there is any discrepancy between the protocol 
and the clinical study site agreement, the clinical study site agreement will prevail.
15.4.2 Clinical Study Registration
To ensure that information on clinical studies reaches the public in a timely manner and to comply 
with applicable laws, regulations and guidance, Takeda will, at a minimum register interventional

clinical studies it sponsors anywhere in the world on ClinicalTrials.gov or other publicly 
accessible websites on or 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. 
As needed Takeda and investigator/site contact information may be made public to support 
participant access to studies via registries. In certain situations/registries, Takeda may assist 
participants or potential participants to find a clinical study by helping them locate study sites 
closest to their homes by providing the investigator name, address, and phone number via 
email/phone or other methods callers requesting study information. Once subjects receive 
investigator contact information, they may call the site requesting enrollment into the study. The 
investigative sites are encouraged to handle the study inquiries according to their established 
subject screening process. If the caller asks additional questions beyond the topic of study 
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 Study Results Disclosure
Takeda will post the results of clinical studies on ClinicalTrials.gov or other publicly accessible 
websites (including the Takeda corporate site) and registries, as required by Takeda 
Policy/Standard, applicable laws and/or regulations. 
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 sponsor’s 
designee will obtain clinical study insurance against the risk of injury to clinical study subjects. 
Refer to the clinical 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.

Note: Tests and procedures should be performed on schedule, but occasional changes are allowable (±2 days) with permission of the medical monitor for holidays, vacations, and 
other administrative reasons. If extenuating circumstances prevent a patient from beginning treatment or completing a scheduled procedure or assessment within this time, the patient 
may continue the study only with the written permission of the medical monitor.
a Unless otherwise noted, the screening visit must occur within 28 days before the day of the first dose of study drug (C0D1). The ICF may be signed more than 28 days before C0D1.
b The symptom-directed physical examination will be conducted at the screening visit, within 3 days before dosing on Day 1 of each treatment cycle, on Day 16 (part 1) or Day 22 
(part 2) of Cycle 0, and at the EOT/early termination visit. The symptom-directed physical examination may be performed at other visits during the treatment cycle at the discretion 
of the investigator.
c Perform vital signs measurement before dosing. On C0D1 only, perform vital signs measurements at 1, 3, and 8 hours (±10 minutes) postdose. Vital signs outside of C0D1 will be 
collected before dosing of TAK-931 as a single determination. Blood pressure should be determined with the patient in a supine position after the patient has been quietly for 
5 minutes. 
d Safety ECG should be acquired predosing and in the supine position after patients have been resting for 5 minutes.
e Triplicate 12-lead ECGs will be performed as detailed in Table 4 below. The schedule for ECG sampling may be modified on the basis of data from previous cohorts. 
f ECHO estimate of the LVEF can be measured as an alternative to MUGA scan.

g Radiological evaluations (computed tomography [CT] scan or magnetic resonance imaging as clinically indicated in areas of known or clinically suspected disease) will be 
employed to assess the status of the patient’s underlying disease. Brain CT scan evaluation at screening is not required in the absence of symptoms. An evaluation of lesions will be 
performed during screening (within 28 days before the first dose of study drug) and every 3rd cycle beginning with Cycle 3. Refer to Section 9.4.15 for details.
h Including serious pretreatment events; see Section 10.1.1. 
i For part 1, Cycle 0 patients will be randomized to Sequence A (1 dose of 80 mg powder-in-capsule [PIC] on Day 1 followed by 1 dose of 80 mg tablet on Day 3) or Sequence B 
(1 dose of 80 mg tablet on Day 1 followed by 1 dose of 80 mg PIC on Day 3). From Day 5 through Day 16 inclusive, all patients regardless of the sequence will receive 1 daily dose 
of TAK-931 50 mg PIC followed by 7 days of rest. For part 2, Cycle 0 patients will be randomized to receive a tablet of TAK-931 on Days 1 either of a fed or a fasted state followed 
by another tablet of TAK-931 on Day 3 in the alternate fasted or fed state. In both sequences, patients will receive 1 dose of TAK-931 on Day 12, followed by 1 tablet QD from 
Days 14 through 22 inclusive. After Day 22 administration, there is a 1-week rest period before Cycle 1 Day 1. In parts 1 and 2 Cycle 1 and after, TAK-931 will be administered on 
Days 1 to 14 inclusive of 21-day cycles. In part 1, the dose for Cycle 1 and after is 50 mg PIC QD. In part 2 TAK-931 will be administered QD in tablets at the dose that produces 
comparable exposure to 50 mg PIC as determined in part 1. The study center staff will cross-check the patient’s diary against the patient’s supply of oral TAK-931 on Days 1 and 14
of each cycle to assess compliance.
j A serum human chorio gonadotropin beta pregnancy test will be performed only for patients of childbearing potential during screening and again at C0D1 (baseline) if the screening 
test was performed more than 4 days before the first dose of any study drug. The results must be negative within 4 days before the first dose of TAK-931 is administered (ie, within the 
4 days before C0D1), or as otherwise required by local regulations. If Cycle 0 Day 1 serum pregnancy results are not available before dosing, a urine pregnancy test may be performed.
Additional pregnancy testing may be performed during the study at the discretion of the investigator, upon request of an independent ethics committee/institutional review board, or 
if required by local regulations. 
k The hematology and chemistry blood samples for C0D1 may be collected within 4 days before dosing to ensure patient eligibility on Day 1. If screening clinical laboratory testing 
was performed within 4 days before the C0D1 dose, it need not be repeated on C0D1. For hematology and chemistry panels, refer to Table 9.a. 
l Time points for blood samples for PK analysis will be collected as specified in Table 4 below. 
m After EOT, only related SAEs must be reported to the sponsor’s Department of Pharmacovigilance or designee. 
n Safety laboratory samples can be collected up to 2 days before the actual visit date. In Cycle 4 and beyond, the hematology and chemistry tests will be conducted on Day 1 of each 
cycle only if, in the opinion of the investigator, it is safe to do so. For hematology and chemistry panels, refer to Table 9.a.

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 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 who will assist in the protocol. If the 
investigator/institution retains the services of any individual or party to perform study related 
duties and functions, the investigator/institution should ensure that this individual or party is 
qualified to perform those study related duties and functions and should implement procedures 
to ensure the integrity of the study related duties and functions performed and any data 
generated.
3. Ensure that study related procedures, including study specific (non routine/non standard panel) 
screening assessments are NOT performed on potential subjects, before the receipt of written 
approval from relevant governing bodies/authorities.
4. Ensure that all colleagues and employees assisting in the conduct of the study are informed of 
these obligations.
5. 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.
6. 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.
7. Ensure that requirements for informed consent, as outlined in 21 CFR Part 50, ICH and local 
regulations, are met.
8. 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 ICF 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 ICF 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.
9. Prepare and maintain adequate case histories of all persons entered into the study, including 
eCRFs, 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 
contact and receive written approval from the sponsor before disposing of any such 
documents.
