Title of Protocol: A Phase 2b, Randomized, Multicenter, 
Double-Blind, Dose-Ranging Study to Assess the Efficacy, 
Safety, and Pharmacokinetics of Intravenous TAK-954 in 
Critically Ill Patients With Enteral Feeding Intolerance
IND No.: 114408
EudraCT No.:
2017-003206-41
Study Number: 2002
Phase: 2b
Study Design:
This is a phase 2b, randomized, multicenter, double-blind, double-dummy, dose-ranging, active-controlled study to 
evaluate the efficacy, safety, and pharmacokinetics (PK) of intravenous (IV) TAK-954 in critically ill subjects with 
enteral feeding intolerance (EFI). The primary objective of this study is to assess the treatment effect of IV TAK-954 
in improving the average daily protein adequacy received through enteral nutrition. 
During the Screening Period, subjects receiving enteral feed and meeting eligibility criteria for enrollment will be 
identified and those that meet the protocol definition of EFI, defined as a single gastric residual volume (GRV) 
measurement of ≥250 mL with vomiting/retching within the last 24 hours or a single GRV measurement of ≥500 mL, 
with or without vomiting/retching within the last 24 hours, will be eligible for randomization. Patients should be 
enrolled within 24 hours of developing EFI. 
Approximately 200 subjects will be enrolled in this study and randomized in a 1:1:1:1 ratio to 1 of 4 parallel treatment 
groups (0.1, 0.3, or 1 mg of TAK-954 diluted to 100 mL with normal saline administered by IV infusion over 
60 minutes once daily (QD) and 2 mL of normal saline IV injection at other times to make a 3 times a day (TID) dosing 
regimen; OR 100 mL normal saline IV infusion over 60 minutes QD and 10 mg metoclopramide [5 mg/mL] IV 
injection TID). Subject randomization will be stratified based on their baseline NUTrition RIsk in Critically Ill 
(NUTRIC) score (either low [0-4] or high [5-9]) to ensure that approximately equal numbers of subjects will be 
randomized into each treatment group from a high or low NUTRIC score group. The study design incorporates 
adaptive features in order to provide an opportunity to modify 1 or more aspects of the study based on accumulating 
data and mitigate the risks associated with unanticipated variability. 
An interim analysis will be performed after approximately 25 subjects within each cohort have completed the study. 
Potential modifications to the design of the study based on Bayesian methods following the interim analysis include: 
dropping of inefficacious dose(s), dropping of doses due to safety concerns, inclusion of new dose(s) (less than 1 mg), 
and sample size adjustment. 
The 24:00 clock will start at the beginning of the treatment infusion on Day 1. Subjects will receive blinded TAK-954 
or metoclopramide at approximately the same time (plus or minus 2 hours) on the dosing days. Subjects will receive 
randomized treatment for a minimum of 5 days and up to a maximum of 14 days. Treatment may be discontinued upon 
EFI resolution and subject’s feeding goal rate is achieved between 5 to 14 days of drug administration. Subjects whose 
EFI resolves and goal feeding rate is achieved earlier will remain on study medication to complete at least 5 days of 
treatment. At the discretion of the treating physician and investigator, the participant may remain on study drug for up 
to 14 days if they remain feed tolerant and they are advanced to their goal feeding rate. All subjects will follow the 
same feeding protocol. Treatment failures by protocol (Figure 6.a) will be discontinued from the study and standard of 
care will be implemented.
Subjects will also be discontinued if continuous tube feeding is no longer being provided in the intensive care unit 
([ICU] eg, the patient is discharged to the ward, liquid nutrient is ceased by treating clinicians and the participant is

allowed oral intake, or new abdominal pathology that requires enterally feeding to be ceased) or the subject dies.
Subjects assessed by the treating physician as requiring different management to what is currently specified in the 
feeding protocol (eg, requiring rescue medication or post-pyloric tube placement) will be considered as treatment 
failures and be withdrawn from study treatment. Subjects with unresolved EFI following the 14-day Treatment Period 
should be managed by the treating physician according to local standard of care. Subjects will be followed up to 
30 days for safety and up to 90 days for cardiovascular events and survival after receiving their last dose of study 
treatment. Choice of feeding formula will be at the discretion of the treating physician but will be within a defined 
nutritional breakdown (1.2 to 2 g/kg/day of proteins and up to 1.5 kcal/mL).
The nutritional requirements of an individual subject will be determined as per standard of care at the site. During the 
Treatment Period, nutritional parameters including nutritional prescription, daily feed volume, calories, and protein 
delivered will be recorded. Blood glucose will be monitored throughout the study and kept within an acceptable range 
according to individual site protocols. Protein homeostasis will be monitored through step wise measurement of 
protein absorption (nitrogen balance), and endogenous protein production (pre-albumin). Indirect measures including 
motilin, cholecystokinin, pancreatic polypeptide, C-reactive protein and interleukin-6 will also be assessed. 
Primary Objective:
The primary objective of this study is to assess the treatment effect of IV TAK-954 in improving the average daily 
protein adequacy received through enteral nutrition. 
Secondary Objectives:
The secondary objectives of this study are to:

Assess the treatment effect of TAK-954 on GRV.

Assess the safety and tolerability of multiple IV doses of TAK-954. 

Assess the treatment effect of TAK-954 on the ability to meet average target daily nutritional goals.

Assess the treatment effect of TAK-954 on clinical outcomes.

Evaluate the PK of TAK-954.
Subject Population: Critically ill subjects admitted to the ICU and identified to have EFI.

Statistical Considerations:
The primary efficacy endpoint will be the average daily protein adequacy received through enteral nutrition (defined 
by % of goal protein delivered per day [% protein goal delivered = actual protein achievement / total patient-specific 
target protein]) over the first 5 days of study treatment. Bayesian methods will be used to assess treatment effect. For 
each comparison between metoclopramide and TAK-954, a non-informative prior will be assumed for the distribution 
of treatment effect. At the end of the study, the posterior distribution of treatment effect for each TAK-954 arm against 
metoclopramide will be derived and 95% credible intervals will be calculated. Additionally, simultaneous 95% 
confidence intervals for each dose of TAK-954 against metoclopramide will also be computed using Dunnett’s 
method.
The safety objectives will be evaluated using safety data through the duration of ICU stay and for up to 90 days after 
the end of treatment and will be listed by subject and summarized by treatment using the frequency of events or 
descriptive statistical summaries, as appropriate. All subjects who received at least 1 dose of study medication will be 
included in the safety evaluation. Summary tables will be provided for AEs, hematology, and chemistry laboratory 
evaluations, vital signs, 12-lead ECG findings, and concomitant medications. Baseline characteristics such as type of 
reason for ICU referral or patient category for mixed ICUs (medical, surgical, burn, trauma), main diagnosis, NUTRIC 
score, Sequential Organ Failure Assessment (SOFA), Acute Physiology and Chronic Health Evaluation (APACHE), 
medication of interests (opioids, propofol, proton pump inhibitors, laxatives) and muscle mass (mid-upper arm 
circumference) measurements will be summarized descriptively. 
Concentration data for each time point for TAK-954 will be summarized by descriptive statistics. 
Descriptive statistics, graphical methods, and statistical modeling as appropriate will be used to explore the 
relationship between baseline levels/response and the levels of various biomarkers.
Sample Size Justification: 
This study will randomize approximately 200 subjects into 4 treatment groups with an initial equal (1:1:1:1) 
randomization scheme. This sample size is based on simulation of go/no-go decision making using a Bayesian 
approach. If a new dose is introduced after the interim analysis, then the randomization scheme may be adjusted to 
increase the proportion of new subjects being assigned to the new dose. Subject randomization will be stratified based 
on their baseline modified NUTRIC score (either low [0-4] or high [5-9]) to ensure that approximately equal numbers 
of subjects will be randomized into each treatment group from a high or low NUTRIC score.
Interim Analysis: 
Interim analysis will be performed after approximately 100 subjects have completed the study; ie, 25 subjects within 
each cohort. Efficacy and safety data will be used to determine if stopping criteria for individual dose groups are met. 
Interim decision making for efficacy will be performed based on a futility stopping rule. Futility assessments in each 
dose group will be conducted based on the predictive probability of success (PPoS) of the primary efficacy endpoint.
The criteria for success for each dose group is that posterior probability (standardized treatment effect >0.2|Data) >
80% based on the updated distribution of the treatment effect at the end of the study. This will be assessed separately 
for each arm, assuming a positive treatment effect indicates improvement. If the PPoS at the interim in a dose group is 
below a pre-determined threshold (20%;), 2 actions may be taken:

The futility stopping rule will be met and patient enrollment will be discontinued in this dosing group. Subjects 
currently in that dosing group will complete the study receiving that dose if safety is not a concern.

Subjects not already randomized will be split equally among any of the remaining dose groups after the interim 
analysis or reassigned to a new dose level.
In addition to the above formal criteria, all available efficacy and safety data from the current study, as well as all 
available data from the other TAK-954 studies, will be used to guide the potential modification of design of the study, 
including dropping of inefficacious dose(s), dropping of doses due to safety concerns, and inclusion of new dose(s) 
(less than 1 mg).

INTRODUCTION
4.1
Background
TAK-954 is a highly selective and potent serotonin type 4 (5-HT4) receptor agonist that has shown 
prokinetic activity throughout the gastrointestinal (GI) tract in experimental models and is being 
developed for short-term (acute) use in the treatment of critically ill patients with enteral feeding 
intolerance (EFI).
Critically ill patients who require enteral feeding frequently have reduced GI motility including 
delayed gastric emptying, and develop EFI, which can lead to several complications including not 
meeting daily calorie and protein requirements [1]. Development of malnourishment in these 
patients is associated with impairment of immunological function, increased risk of infection, 
prolongation of mechanical ventilation, increased length of intensive care unit (ICU) and hospital 
stay, and ultimately higher mortality [2,3].
Nonclinical studies completed to date include a safety pharmacology battery (neurobehavioral, 
cardiovascular, and respiratory systems), intravenous (IV) and oral single-dose studies in rats, oral 
single-dose studies in dogs, and oral 28-day and 13-week repeat-dose studies in rats and dogs. 
TAK-954 was also tested in in vitro and in vivo genotoxicity studies, embryo-fetal toxicity studies 
in rats and rabbits, and ex vivo and in vivo local tolerance studies. Toxicokinetic analysis of 
TAK-954 plasma levels was conducted in the Good Laboratory Practice repeat-dose studies.

The purpose of this phase 2, randomized, multicenter, double-blind, double-dummy, dose-ranging, 
active-controlled study is to evaluate the safety, efficacy, and PK of IV TAK-954 in critically ill 
subjects with EFI.
Please refer to the TAK-954 Investigator’s Brochure for complete information on the 
investigational product.
This study will be conducted in compliance with the protocol, Good Clinical Practice (GCP), and 
the applicable regulatory requirements.
4.2
Rationale for the Proposed Study
Critical illness is typically associated with a catabolic stress state and critically ill patients are at 
particular risk of malnutrition, which can occur in up to 50% of cases and is a significant clinical 
issue associated with increased morbidity and mortality [4-8].
Evidence favors the initiation of early enteral nutrition (EN) as opposed to parental nutrition (PN)
(unless otherwise contraindicated) in critically ill patients, particularly those at high nutritional 
risk (ie, at high risk for under-nutrition and/or malnutrition). Of those that do receive enteral 
feeding, a large proportion of patients receive inadequate nutrition placing them at high risk for 
malnutrition or worsening of pre-existing malnutrition [4-9]. One of the key factors contributing to 
the development or worsening of existing malnutrition in critically ill patients is impaired GI 
motility, which is common in ICU patients and associated with serious complications [10-15].
Impaired GI motility is the primary cause for EFI; a condition characterized by high gastric 
residual volume (GRV), and vomiting with an associated increased risk for aspiration and 
aspiration pneumonia [10,16,17]. Results of a retrospective analysis of data from an international 
observational cohort study of nutrition practices among 167 ICUs demonstrated that in critically ill,

mechanically-ventilated patients receiving EN via the intragastric route, feeding intolerance 
occurred frequently (approximately one-third of patients) and was associated with a reduction in 
the amount of nutrients delivered to patients, increased days with ventilation, longer duration of 
ICU stay, and increased mortality [15].
The longer it takes for adequate nutrition to be provided, the greater the nutritional deficit, 
contributing to the undernourishment in this at-risk group. As a result, re-establishment of enteral 
feeding to deliver the required daily calorie and protein is 1 of the goals of management of EFI, in 
line with current standard of care [18]. 
Strategies to prevent motility disorders in critically ill patients include head elevation, minimizing 
drugs with inhibitory effect on motility, ensuring electrolyte and fluid balance, and alternative 
perioperative anesthesia where possible.
Pharmacologic agents most commonly used for treating EFI are prokinetics. These are used 
off-label and in the short-term (generally <7 days) to treat EFI once it has occurred or to support 
enteral feeding. Prokinetic agents such as metoclopramide and erythromycin have demonstrated 
some efficacy in critical illness-related GI dysmotility although data are inconsistent. These agents 
have significant limitations including: they primarily affect upper GI tract motility (stomach, 
proximal small bowel), are associated with rapid tachyphylaxis (after 3 to 4 days), and are 
associated with SAEs [11-13,19-23]. 
5-HT4 agonists have proven therapeutic potential in patients with GI motility disorders [20,24]. 
However, earlier agents lacked 5-HT4 selectivity and their off-target activity increased the risk for 
important adverse effects. For example, metoclopramide, which is a dopamine-2 receptor 
antagonist, serotonin type 3 (5-HT3) receptor antagonist, and indirect enhancement of cholinergic 
neurotransmission can cause extrapyramidal and cardiovascular effects; cisapride, which is a 
5-HT4 receptor agonist can cause cardiac dysrhythmias; and tegaserod, which is a serotonin type 1 
and 2 (5-HT1 and 5-HT2) receptor agonist/antagonist, can cause ischemic cardiovascular adverse 
effects [20,25].
The development of highly selective 5-HT4 receptor agonists (eg, velusetrag, naronapride, 
prucalopride) has resulted in more favorable benefit-to-risk profiles for this drug class due to much 
lower affinity for targets known to be associated with serious adverse effects. TAK-954 belongs to 
this group of compounds of highly selective 5-HT4 receptor agonists. It is a potent, highly selective, 
5-HT4 receptor agonist with evidence of activity throughout the GI tract and low risk for off-target 
effects. Impaired GI motility associated with critical illness may affect multiple GI segments. 
Therefore, a prokinetic agent with activity beyond the upper GI tract may be more effective in 
improving overall GI motility and the complication of EFI than agents that primarily affect the 
stomach and upper small bowel.
TAK-954 is being developed for short-term use for the treatment of patients with EFI. TAK-954 
has prokinetic effects that can be targeted at impaired GI motility which is the most common 
barrier to delivering adequate nutrition via enteral feeding in critically ill patients. Within an ICU 
setting, an IV formulation is convenient and desired. TAK-954 will be delivered as an IV 
administration when patients are confirmed as having EFI.

4.3
Benefit/Risk Profile 
Study participants with EFI are expected to see an improvement based on the prokinetic effect of 
TAK-954 and metoclopramide. 
Potential risks of TAK-954 use include findings from prior studies; there were no SAEs or severe 
AEs observed in 2 oral dose studies in healthy volunteers, Studies 0060 and 0061. Following 
multiple IV doses in healthy subjects in Study 0095, TAK-954 was generally well tolerated at 
doses ranging from 0.1 to 0.5 mg QD for 5 consecutive days. No SAEs were reported. The most 
common AEs (ie, headache and postural dizziness) were not serious and resolved with treatment 
discontinuation.
The principal mitigation for these risks includes appropriate selection of the study populations, 
detailed safety plan for important potential and identified risks, which permits close monitoring, 
including regular neurological examination, and rapid institution of appropriate care as needed, 
and utilization of experienced ICU staff trained in study procedures. 
Metoclopramide is currently the most widely used prokinetic agent in treating ICU patients who 
develop EFI and has a well-established safety profile that includes hyperprolactinemia and 
extrapyramidal disorders (acute dystonia) that are generally completely reversible after treatment 
discontinuation. Chronic metoclopramide use can be associated with tardive dyskinesia, which is 
characterized by involuntary movements of the face, tongue or extremities that may not reverse 
after discontinuation of the treatment, but this is a rare complication described only after usage of 
metoclopramide for at least 3 months. The pharmacological effects of metoclopramide in 
enhancing peristalsis and GI motility are driven by antagonism of the dopamine-2/dopamine-3 
receptors and peripheral 5-HT4 agonist effect. The treatment will last only until the resolution of 
EFI or for a maximum of 14 days. 
Overall, the risk:benefit profile is therefore considered appropriate for this study.

STUDY DESIGN AND DESCRIPTION
6.1
Study Design
This is a phase 2b, randomized, multicenter, double-blind, double-dummy, dose-ranging, 
active-controlled study to evaluate the efficacy, safety, and PK of IV TAK-954 in critically ill 
subjects with EFI. 
During the Screening Period, subjects receiving enteral feed and meeting eligibility criteria for 
enrollment will be identified and those that meet the protocol definition of EFI, defined as a single 
GRV measurement of ≥250 mL with vomiting/retching within the last 24 hours, or a single GRV 
measurement of ≥500 mL with or without vomiting/retching within the last 24 hours, will be 
eligible for randomization. Patients should be enrolled within 24 hours of developing EFI.
Approximately 200 subjects will be enrolled in this study and randomized in a 1:1:1:1 ratio to 1 of 
4 parallel treatment groups (0.1, 0.3, or 1 mg of TAK-954 diluted to 100 mL with normal saline 
administered by IV infusion over 60 minutes QD and 2 mL of normal saline IV injection at other 
times to make a 3 times a day (TID) dosing regimen; or 100 mL normal saline IV infusion over 60 
minutes QD and 10 mg metoclopramide [5 mg/mL] IV injection TID). Subject randomization will 
be stratified based on their baseline NUTRIC score (either low [0-4] or high [5-9]) to ensure that 
approximately equal numbers of subjects will be enrolled in each treatment group from a high or 
low NUTRIC score group. The study design incorporates adaptive features in order to provide an 
opportunity to modify 1 or more aspects of the study based on accumulating data and mitigate the 
risks associated with unanticipated variability.
An interim analysis will be performed after approximately 100 subjects (ie, 25 subjects within 
each cohort) have completed the study. Potential modifications to the design of the study based on 
Bayesian methods following the interim analysis include: dropping of inefficacious dose(s), 
dropping of doses due to safety concerns, and inclusion of new dose(s) (less than 1 mg).
The 24:00 clock will start at the beginning of the treatment infusion on Day 1. Subjects will receive 
blinded TAK-954 or metoclopramide at approximately the same time each day (plus or minus 
2 hours) on the dosing days. Subjects will receive randomized treatment for a minimum of 5 days 
and up to a maximum of 14 days. Treatment may be discontinued upon EFI resolution and 
subject’s feeding goal rate is achieved between 5 to 14 days of drug administration. Subjects 
whose EFI resolves and goal feeding rate is achieved earlier will remain on study medication to 
complete at least 5 days of treatment. At the discretion of the treating physician and investigator, 
the participant may remain on study drug for up to 14 days if they remain feed tolerant and they are 
advanced to their goal feeding rate. All subjects will follow the same feeding protocol. Treatment 
failures by protocol (Figure 6.a) will be discontinued from the study and standard of care will be 
implemented.
Subjects will also be discontinued if continuous tube feeding is no longer being provided in the 
ICU (eg, the patient is discharged to the ward, liquid nutrient is ceased by treating clinicians and 
the participant is allowed oral intake, or new abdominal pathology that requires enterally feeding 
to be ceased) or the subject dies.

The nutritional requirements of an individual subject will be determined as per standard of care at 
the site. During the Treatment Period, nutritional parameters including nutritional prescription, 
daily feed volume, calories, and protein delivered will be recorded. Blood glucose will be 
monitored throughout the study and kept within an acceptable range according to individual site 
protocols. Protein homeostasis will be monitored through stepwise measurement of protein 
absorption (nitrogen balance) and endogenous protein production (pre-albumin). Indirect 
measures including C-reactive protein (CRP) and interleukin-6 (IL-6) will also be assessed. 
A schematic of the study design is included as Figure 6.b. A schedule of assessments is listed in 
Appendix A.

Justification for Study Design, Dose, and Endpoints
Study Design: 
The definition of EFI is inconsistent across the literature, but patients with EFI are often diagnosed 
at the bedside based on the presence of a “large” GRV. The definition of a “large” GRV is variable 
across studies, though a recent systematic review of the literature identified 250 mL as the most 
widely used threshold [26]. The presence of symptoms suggestive of impaired GI motility such as 
vomiting is often used alone or in combination with large GRVs to support the diagnosis of EFI. 
The inter-observer reliability of GI symptoms suggestive of EFI has not been previously assessed 
but can be problematic; and thus some matter experts suggest using a combination of both large 
GRVs and symptoms as a more appropriate approach that can improve inter-observer reliability 
[26].
The validity of this approach is supported by the results of an observational study including data 
from 1888 critically ill patients from 167 ICUs in 21 countries. In this study, critically ill patients 
with EFI defined by the presence of large GRVs (>200 mL) alone or in combination with 

TAK-954
Study No. 2002

Protocol Incorporating Amendment No. 01

symptoms received significantly less feed volume, had fewer ventilator-free days and increased 
ICU stay compared with those without EFI [15]. The symptom most commonly associated with 
EFI was vomiting/retching. The relation between large GRVs (>300 mL) and poor clinical 
outcomes was also confirmed by Wang et al in a study including 455 ICU patients and 
255 non-ICU patients [27].
Our study is proposing a definition of EFI based on the presence of GRV ≥250 mL and 
vomiting/retching within the last 24 hours, which appear to be in agreement with current daily 
practice [15,26,28] or GRV≥ 500 mL with or without vomiting/retching within the last 24 hours, 
the latter criteria having been endorsed by the recent European Society of Intensive Care Medicine 
clinical practice guidelines and American Society for Parenteral and Enteral Nutrition 
recommendations. 
In critically ill patients with feeding intolerance, therapeutic options include the use of prokinetic 
agents, PN, or post-pyloric placement of a feeding tube. Prokinetic agents, however, are 
considered first-line treatment [29]. Of the available pharmaceutical options, metoclopramide is 
currently the most widely used prokinetic agent in treating ICU patients who develop EFI. Its GI 
motility effect is due to dopamine antagonist effect, enhancing peristalsis in the upper GI [30], and 
peripheral 5-HT4 agonist effect [31]. As such, metoclopramide IV (10 mg TID) has been selected 
as the comparator in this study.
The use of placebo in this patient population, therefore, would not only pose challenges to 
recruitment due to misalignment with current clinical practice, but would also be considered 
unethical given the nature of the condition. 
For this study, minimal treatment duration of 5 days has been established based on the average 
duration of EFI [15] with the possibility to extend the treatment duration for up to 14 days for 
outlier patients with persistent or relapsing intolerance.

In studies in which metoclopramide has been used in the treatment of patients with EFI, doses have 
included 10 mg IV TID and 10 mg IV 4 times a day [32-36]. Due to concerns regarding 
neurological and other AEs associated with metoclopramide, the United States, Europe, and other 
countries have restricted its use with a dose and duration limitation. In this study, metoclopramide 
IV 10 mg TID will be used for up to 14 days.
Study Endpoints
Most feeding protocols in the ICU recommend stopping, withholding, or reducing enteral feeding 
in the presence of large GRVs [37]. Accordingly, patients with EFI are less likely to achieve 
nutritional targets and thus are at increased risk of malnutrition complications and worse outcomes. 
Therefore, the main goals of our study are to assess the ability of TAK-954, a selective 5-HT4
agonist with prokinetic activity, to improve nutritional goals by decreasing GRVs and thus 
preventing feeding protocol interruptions or decreasing rate of delivery. Improvement of GI 
motility should also help to prevent malnutrition complications by facilitating the delivery of 
nutrients from the stomach to the intestine. In fact, a growing body of evidence suggests that 
increased delivery of nutrients, especially proteins, is associated with better clinical outcomes 
[38-40]. The primary efficacy endpoint of this study will, therefore, be the average daily protein 
adequacy received through enteral nutrition (defined by % of goal protein delivered per day [% 
protein goal delivered = actual protein achievement/total patient-specific target protein]) over the 
first 5 days of study treatment.

The primary reason for discontinuation or withdrawal of the subject from the study or study drug 
should be recorded in the electronic case report form (eCRF) using the following categories. For 
screen failure subjects, refer to Section 9.1.20.
1. Treatment failures:

Subjects assessed by the treating physician as requiring different management to what is 
currently specified in the feeding protocol (eg, requiring rescue medication or post-pyloric 
tube placement) will be considered as treatment failures and be withdrawn from study 
treatment.

TAK-954
Study No. 2002

CONFIDENTIAL

Treatment failures by protocol (Figure 6.a) will be discontinued from the study and 
standard of care will be implemented.
2. Subjects will also be discontinued if continuous tube feeding is no longer being provided in the 
ICU (eg, the patient is discharged to the ward, liquid nutrient is ceased by treating clinicians 
and the participant is allowed oral intake, or new abdominal pathology that requires enterally 
feeding to be ceased) or the subject dies.
3. Treatment discontinuation due to an AE: The subject has experienced an AE that requires early 
termination because continued participation imposes an unacceptable risk to the subject’s 
health or the subject is unwilling to continue because of the AE. Specific events that require 
treatment discontinuation (see Section 10.1.6) include:

Prolonged QT: Second episode of G2 (QTcF >480 and ≤500 msec), Grade 3 (QTcF 
>500 msec) or Grade 4 (QTcF >500 msec or >60 msec change from Baseline with 
Torsades de pointes or polymorphic ventricular tachycardia or signs/symptoms of serious 
arrhythmia).

Second or third degree heart block. Treatments with study drug may be continued in 
second degree heart block Mobitz I (Wenckebach) after medical monitor review.

Second occurrence of G4 (life threatening) SVT that is considered related by the 
investigator.

Suspected serotonin syndrome.

G2–G4 extrapyramidal disorder.
4. Liver function tests: 

Subjects with ALT<3×ULN at Baseline who develop ALT >3×ULN with total bilirubin 
>2×ULN while on treatment with study drug. 

Subjects with ALT 3 to 8×ULN at Baseline who develop a 2-fold increase in ALT over the 
Screening value.
5. Study drug interruption for 2 consecutive days.
6. Lost to follow-up. The subject did not return to the clinic and attempts to contact the subject 
were unsuccessful. Attempts to contact the subject must be documented in the subject’s source 
documents.
7. Voluntary withdrawal. The subject (or subject’s LAR) wishes to withdraw from the study. The 
reason for withdrawal, if provided, should be recorded in the eCRF.
Note: All attempts should be made to determine the underlying reason for the withdrawal and, 
where possible, the primary underlying reason should be recorded (ie, withdrawal due to an 
AE should not be recorded in the “voluntary withdrawal” category.
8. Study termination. The sponsor, IRB, IEC or regulatory agency terminates the study.
9. Pregnancy. The subject is found to be pregnant.

Procedures for Discontinuation or Withdrawal of a Subject
The investigator may discontinue a subject’s study participation at any time during the study when 
the subject meets the study termination criteria described in Section 7.5. In addition, a subject (or 
subject’s LAR) may discontinue his or her participation without giving a reason at any time during 
the study. Should a subject’s participation be discontinued, the primary criterion for termination 
must be recorded by the investigator. In addition, efforts should be made to perform all procedures 
scheduled for the Early Termination Visit. Discontinued or withdrawn subjects will not be 
replaced.

Overdose
An overdose is defined as an accidental administration of study drug, to a study subject, at a dose 
above that which is assigned to that individual subject according to the study protocol.
All cases of overdose (with or without associated AEs) will be documented in an Overdose page of 
the eCRF, in order to capture this important safety information consistently in the database. Cases 
of overdose without manifested signs or symptoms are not considered AEs. AEs associated with 
an overdose will be documented on AE eCRF(s) according to Section 10.0.
SAEs associated with overdose should be reported according to the procedure outlined in 
Section 10.2.2.
TAK-954 has been investigated in clinical studies up to 20 mg orally. AEs observed at 5 mg orally 
(exposure approximately 3-fold higher than that predicted for a 1 mg IV dose) or higher included 
mild orthostatic hypotension in 1 subject after they received a single oral 5 mg dose and mild AV 
dissociation in 2 subjects after they received a single oral 10 mg dose. In the event of an IV 
overdose, discontinue the treatment of study drug, treat the subject symptomatically and provide 
supportive care as needed. Dialysis is not anticipated to be of benefit.
8.2
Study Drug Assignment and Dispensing Procedures
The investigator or the investigator’s designee will access the Interactive Response Technology 
(IRT) at Screening to obtain the subject study number. The investigator or the investigator’s 
designee will also utilize the IRT to randomize the subject into the study. During this contact, the 
investigator or designee will provide the necessary subject-identifying information, including the 
subject number assigned at Screening. Subjects will be assigned in a 1:1:1:1 ratio to receive the 

TAK-954
Study No. 2002

Protocol Incorporating Amendment No. 01
28 February 2018
CONFIDENTIAL
treatments of 0.1, 0.3, 1.0 mg of TAK-954, or 10 mg metoclopramide according to the 
randomization schedule. 
Subject randomization will be stratified based on their baseline NUTRIC score (either low [0-4] or 
high [5-9]) to ensure that approximately equal numbers of subjects will be enrolled in each 
treatment group from a high or low NUTRIC score group.
Specific procedures related to treatment assignment/dispensation, requests for resupply of study 
drug, or reporting of lost or damaged shipments of study drug are outlined in the Study Manual.
8.3
Randomization Code Creation and Storage
Randomization personnel of the sponsor/ the designee of the sponsor will generate the 
randomization schedule and will provide it to the IRT vendor before the start of this study. All 
randomization information will be stored in a secured area, accessible only by authorized 
personnel.
8.4
Study Drug Blind Maintenance 
The study drug blind will be maintained using the IRT.
Since the maintenance of the blind may be compromised because of results from drug 
concentrations and/or PD assessments, such results should not be disclosed before formal 
unblinding of study. In the event that results must be reported to the investigator before breaking 
the blind, all efforts should be made to maintain the blind (eg, as changing a medication 
identification [ID] number in order to avoid identification of subjects by the laboratory site 
personnel).
8.5
Unblinding Procedure 
For unblinding a subject, the study drug blind can be obtained by the investigator, by accessing the 
IRT. 
The sponsor must be notified as soon as possible if the study drug blind is broken. The date, time, 
and reason the blind is broken must be recorded in the source documents and the same information 
(except the time) must be recorded on the eCRF.
If any site personnel are unblinded, study drug must be stopped immediately and the subject must 
be withdrawn from the study. 
8.6
Accountability and Destruction of Sponsor-Supplied Drugs
Drug supplies will be counted and reconciled at the site before being returned to the sponsor or 
designee or destroyed locally.
The investigator or designee must ensure that the sponsor-supplied drug is used in accordance with 
the protocol and is dispensed only to subjects enrolled in the study. To document appropriate use 
of sponsor-supplied drug, the investigator or designee must maintain records of all 

TAK-954
Study No. 2002

Protocol Incorporating Amendment No. 01
28 February 2018
CONFIDENTIAL
sponsor-supplied drug delivery to the site, site inventory, dispensation and use by each subject, and 
return to the sponsor or designee.
Upon receipt of sponsor-supplied drug, the investigator or designee must verify the contents of the 
shipments against the packing list. The verifier should ensure that the quantity is correct, and the 
medication is in good condition. If quantity and conditions are acceptable, investigator or designee 
should acknowledge the receipt of the shipment as instructed per the documentation 
accompanying the shipment. If there are any discrepancies between the packing list versus the 
actual product received, the sponsor or its designee must be contacted to resolve the issue. The 
packing list should be filed in the investigator’s essential document file.
The investigator or designee must maintain 100% accountability for all sponsor-supplied drugs 
received and dispensed during his or her entire participation in the study. Proper drug 
accountability includes, but is not limited to:

Frequently verifying that actual inventory matches documented inventory.

Verifying that the log is completed for the drug lot/medication ID used to prepare each dose.

Verifying that all containers used are documented accurately on the log.

Verifying that required fields are completed accurately and legibly.
If any dispensing errors or discrepancies are discovered, the sponsor must be notified immediately.
The IRT will include all required information as a separate entry for each subject to whom 
sponsor-supplied drug is dispensed.
The investigator or designee must record the current inventory of all sponsor-supplied drugs on a 
sponsor-approved drug accountability log. The following information will be recorded at a 
minimum: protocol number and title, name of investigator, site identifier and number, description 
of sponsor-supplied drugs, expiry date and amount dispensed including initials, and signature of 
the person dispensing the drug. The log should include all required information as a separate entry 
for each subject to whom sponsor-supplied drug is dispensed. 
Before site closure or at appropriate intervals, a representative from the sponsor or its designee will 
perform sponsor-supplied drug accountability and reconciliation before sponsor-supplied drugs 
are returned to the sponsor or its designee for destruction or destroyed locally. The investigator or 
designee will retain a copy of the documentation regarding sponsor-supplied drug accountability, 
return, and/or destruction, and originals will be sent to the sponsor or designee.
The investigator will be notified of any expiry date or retest date extension of sponsor-supplied 
drug during the study conduct. On expiry date notification from the sponsor or designee, the site 
must complete all instructions outlined in the notification, including segregation of expired 
sponsor-supplied drug for return to the sponsor or its designee for destruction or destroyed locally.
In the event of expiry date extension of sponsor-supplied drug already at the study site, 
sponsor-supplied drugs may be relabeled with the new expiry date at that site. In such cases, the 
sponsor or its designee will prepare additional labels, certificates of analyses, and all necessary 
documentation for completion of the procedure at the sites.

time that informed consent is obtained, and used throughout the subject's participation in the study.
9.1.2
Demographics, Medical History, and Medication History Procedure
Demographic information to be obtained may include date of birth, sex, and ethnicity (as described 
by the subject or subject representative), height, weight, and smoking status of the subject at 
Screening if available.
Medical history to be obtained will include determining whether the subject has any significant 
conditions or diseases relevant to the disease under study that resolved at or prior to signing of 
informed consent. Ongoing conditions are considered concurrent medical conditions (see 
Section 9.1.8). Medication history information to be obtained includes any medication relevant to 
eligibility criteria stopped at or within 72 hours before signing of informed consent.
A number of additional characteristics will be recorded at Baseline including patient/ICU type (eg, 
medical, surgical, burn, trauma), disease severity (Acute Physiology and Chronic Health 
Evaluation [APACHE] and Sequential Organ Failure Assessment [SOFA]), nutritional risk 
(NUTRIC score: variables include age, APACHE II, SOFA, number of comorbidies, and days 
from hospitalization to ICU admission), protein metabolism (nitrogen balance) and muscle mass 
measurement variables, comorbidity and comedication use (including opioids, anesthetics and 
noradrenergic agents), and medications of interest (opioids, propofol, proton pump inhibitors, 
laxatives) to evaluate the prognostic value of these baseline characteristics on treatment outcomes.
9.1.3
Physical Examination Procedure
A baseline physical examination (defined as the assessment before first dose of study drug) will 
consist of the following body systems: (1) cardiovascular system; (2) respiratory system; (3) GI 
system; (4) nervous system looking mainly for hypertonicity, reflexes, and clonus; and (5) other. 
All subsequent physical examinations should assess clinically significant changes from the 
assessment before first dose examination. This should be recorded in the medical history page or 
as a pretreatment SAEs deemed related to study procedures, if applicable.

Neurological examinations looking for hypertonicity, reflexes, and clonus will also be performed 
at Baseline, on Days 2, 5, 8, and 12, and at 3 days following the last dose.
9.1.4
Weight, Height and BMI
A subject should have weight and height collected as per the standard of care. Body mass index 
(BMI) will be derived from the subject’s height and weight. 
9.1.5
Vital Sign Procedure
Vital signs will include semi-supine blood pressure (systolic and diastolic) and pulse (beats per 
minute). Clinically significant abnormal blood pressure and respiratory rate will be captured as an 
AE as per National Cancer Institute Common Terminology Criteria for Adverse Events (NCI 
CTCAE) v4.03.
9.1.6
Documentation of Nutritional Content of Feed
All subjects will have recorded the calorie, protein, and fat content of the feed being received per 
mL. Feed should be commercially available and have a calorie content between 1.0 and 
1.5 kcal/mL. Protein content of feed used at a particular site should be consistent within 
1.2-2 g/kg/day and therefore supplemental protein for individual patients is not allowed. It is 
recommended that the same feed is used for all subjects at each site.
9.1.7
Documentation of Concomitant Medications
Concomitant medication is any drug given in addition to the study drug. These may be prescribed 
by a physician. Concomitant medication is not provided by the sponsor. On each study day, 
subjects, their representatives or their treating physician will provide information on use of any 
medication other than the study drug (used from signing of informed consent through the end of 
the study), and all medication must be recorded in the eCRF.
9.1.8
Documentation of Concurrent Medical Conditions
Concurrent medical conditions are those significant ongoing conditions or diseases that are present 
at signing of informed consent. This includes clinically significant laboratory, ECG, or physical 
examination abnormalities noted at the Screening examination, according to the judgment of the 
investigator. The condition (ie, diagnosis) should be described and the reason for admittance to 
ICU should be recorded.
9.1.9
Procedures for Clinical Laboratory Samples
All samples will be collected in accordance with acceptable laboratory procedures. Details of these 
procedures and required safety monitoring will be given in the laboratory manual. 
Table 9.a lists the tests that will be obtained for each laboratory specimen.

A baseline 24-hour urine sample will be taken to assess nitrogen balance as soon as the subject is 
enrolled and at Day 5 or end of treatment.
9.1.10 Contraception and Pregnancy Avoidance Procedure
Animal studies for TAK-954 have demonstrated embryotoxicity and there is a lack of adequate 
reproductive toxicity data in humans. 
Given that TAK-954 did not exhibit genotoxic potential in the standard battery of genotoxicity 
assays and the t1/2z of TAK-954, the duration of contraception for 30 days is considered acceptable. 
This is in line with the Clinical Trials Facilitation Group “Recommendations related to 
contraception and pregnancy testing in clinical trials”.
Females of reproductive potential, as well as fertile men and their partners who are female of 
reproductive potential, must agree to abstain from sexual intercourse or to use 2 highly effective 
forms of contraception from the time of giving informed consent, during the study, and for 30 days 

TAK-954
Study No. 2002
Page 47 of 95
Protocol Incorporating Amendment No. 01

(females and males) following the last dose of study drug. An effective form of contraception is 
defined as hormonal oral contraceptives, injectables, patches, intrauterine devices, double-barrier 
method (eg, synthetic condoms, diaphragm, or cervical cap with spermicidal foam, cream, or gel) 
or male partner sterilization.
The following definitions apply for contraception and pregnancy avoidance procedures:
A woman is considered a woman of childbearing potential (fertile) following menarche and until 
becoming postmenopausal unless permanently sterile. Permanent sterilization methods include 
hysterectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 
12 months without an alternative medical cause. 
Sterilized males should be at least 1 year postbilateral vasectomy and have confirmed that they 
have obtained documentation of the absence of sperm in the ejaculate or have had bilateral 
orchidectomy.
9.1.11 Pregnancy
If any subject is confirmed to be pregnant during the study, she should be withdrawn and TAK-954 
should be immediately discontinued. In addition, any pregnancies in the partner of a male subject 
during the study or for 30 days after the last dose should also be recorded following authorization 
from the subject’s partner. A pregnancy notification form should be submitted within 24 hours of 
learning of the pregnancy to the contact listed in Section 1.0.
If the female subject and/or female partner of a male subject agree to the primary care physician 
being informed, the investigator should notify the primary care physician that the female 
subject/female partner of the subject was participating in a clinical study at the time she became 
pregnant and provide details of the study drug the subject received.
All pregnancies, including female partners of male subjects, in subjects on active study drug will 
be followed up to final outcome, using the pregnancy form. The outcome, including any premature 
termination, must be reported to the sponsor. An evaluation after the birth of the child will also be 
conducted.
9.1.12 ECG
A standard single 12-lead ECG will be performed as follows:

Before the 60-minute IV infusion on Day 1 (Baseline).

Days 1 and 2:
–
Approximately 1, 2, and 8 hours after the start of the 60-minute infusion.

At the end of the infusion (approximately 1 hour after the start of the 60 minute IV infusion) on 
every other day of treatment. 

At the end of the infusion (approximately 1 hour after the start of the 60 minute IV infusion) on 
the last day of study drug.

CONFIDENTIAL
In addition, a 12-lead ECG will be performed when needed, if a subject develops symptoms 
suggestive of cardiovascular origin (eg, dizziness, chest pain).
The investigator (or a qualified observer at the study site) will interpret the ECG using 1 of the 
following categories: within normal limits, abnormal but not clinically significant, or abnormal 
and clinically significant. Clinically significant findings from ECGs or cardiac telemetry will be 
captured as AEs as per CTCAE v4.03. The time that a 12 lead ECG was performed will be 
recorded. The following parameters will be recorded on the eCRF from the subject’s ECG trace: 
heart rate, RR interval, PR interval, and QT interval. The sponsor will derive QTcF. 
Holter monitoring for approximately 10 subjects per study arm is ONLY required for the first 
24 to 48 hours following the start of study infusion. This assessment would be performed only in a 
subset of sites.
9.1.13 Pharmacogenomic Sample Collection
9.1.13.1 Optional Pharmacogenomic(PGx) Sample Collection
Consent must be obtained from the subject or LAR prior to collection of the whole blood. 
DNA forms the basis for the genes that make the body produce proteins such as enzymes, drug 
transporters or drug targets, and may be evaluated for the genetic contribution how the drug is 
broken down, or how the drug affects the body. This is called a “Pharmacogenomics research 
study.” Specific purposes of this study include:

Identifying genetic reasons why certain people respond differently to TAK-954.

Finding out more information about how TAK-954 works.

Generating information needed for research, development, and regulatory approval of tests to 
predict response to TAK-954.

Identifying variations in genes related to the biological target of TAK-954.

Identifying the presence of allelic variants in drug metabolizing enzymes, drug transporters, or 
putative drug targets.
This information may be used, for example, to develop a better understanding of the safety and 
efficacy of TAK-954 and other study drugs, to increase understanding of the disease/condition 
being studied, and for improving the efficiency, design and study methods of future research 
studies.
Detailed instructions for collection, storing, handling, and shipping samples will be provided in the 
laboratory manual.
9.1.14 Glucose Monitoring
Blood glucose will be monitored throughout the study and kept within an acceptable range as per 
local guidelines.

9.1.16.1 Collection of Plasma for PK Sampling
Subjects will have PK samples collected prior to and at the end of the infusion, and an additional 
3 samples after the end of the infusion on Days 1, 5, and the last day of dosing. The 3 PK samples 
should be taken as far apart as possible (at least 2 hours apart) and are recommended to be taken at 
3, 8 and 12 hours postinfusion on Days 1, 5, and the last day of dosing. A trough (predose) sample 
will be obtained on Days 2, 4, and 6. Times indicated are relative to the start of the infusion. It is 
important that date and time of each sample collection be accurately recorded. The date and time of 
start and end of infusion should also be accurately recorded. If indicated, these collected samples 
may also be assayed in an exploratory manner for metabolites and/or additional PD markers if 
deemed necessary for interpretation of the data.

PRETREATMENT EVENTS AND ADVERSE EVENTS
10.1
Definitions
10.1.1 Pretreatment SAEs
After informed consent, but before initiation of study medications, only SAEs caused by a 
protocol-mandated intervention will be collected (eg, SAEs related to invasive procedures).
10.1.2 AEs
An AE is defined as any untoward medical occurrence in a clinical investigation subject 
administered a drug; it does not necessarily have to have a causal relationship with this treatment.
An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal 
laboratory value), symptom, or disease temporally associated with the use of a drug whether or not 
it is considered related to the drug.
10.1.3 Additional Points to Consider for AEs
An untoward finding generally may:

Indicate a new diagnosis or unexpected worsening of a pre-existing condition. (Intermittent 
events for pre-existing conditions or underlying disease should not be considered AEs.)

Necessitate therapeutic intervention.

Require an invasive diagnostic procedure.

Require discontinuation or a change in dose of study drug or a concomitant medication.

Be considered unfavorable by the investigator for any reason.

Untoward finding caused by a study procedure (eg, a bruise after blood draw) should be 
recorded as an AE.
Diagnoses vs signs and symptoms:

Each event should be recorded to represent a single diagnosis. Accompanying signs (including 
abnormal laboratory values) or symptoms should NOT be recorded as additional AEs. If a 
diagnosis is unknown, sign(s) or symptom(s) should be recorded appropriately as AE(s).
Laboratory values and ECG findings:

Changes in laboratory values are only considered to be AEs if they are judged to be clinically 
significant (ie, if some action or intervention is required or if the investigator judges the change 
to be beyond the range of normal physiologic fluctuation). A laboratory test and/or continued 
monitoring of an abnormal value or finding are not considered an intervention. In addition, 
repeated or additional noninvasive testing for verification, evaluation or monitoring of an 
abnormality is not considered an intervention.

TAK-954
Study No. 2002
Page 53 of 95
Protocol Incorporating Amendment No. 01
28 February 2018
CONFIDENTIAL

If abnormal laboratory values are the result of pathology for which there is an overall diagnosis 
(eg, increased creatinine in renal failure), the diagnosis only should be reported appropriately 
as an AE.
Pre-existing conditions:

Pre-existing conditions (present at the time of signing of informed consent) are considered 
concurrent medical conditions and should NOT be recorded as AEs. If the subject experiences 
a worsening or complication of such a concurrent medical condition, the worsening or 
complication should be recorded appropriately an AE (worsening or complication occurs after 
start of study drug). Investigators should ensure that the event term recorded captures the 
change in the condition (eg, “worsening of…”).

If a subject has a pre-existing episodic concurrent medical condition (eg, asthma, epilepsy) any 
occurrence of an episode should only be captured as an AE if the condition becomes more 
frequent, serious or severe in nature. Investigators should ensure that the AE term recorded 
captures the change in the condition from Baseline (eg “worsening of…”).

If a subject has a degenerative concurrent medical condition (eg, cataracts, rheumatoid 
arthritis), worsening of the condition should only be recorded as an AE if occurring to a greater 
extent to that which would be expected. Investigators should ensure that the AE term recorded 
captures the change in the condition (eg, “worsening of…”).
Worsening of AEs:

If the subject experiences a worsening or complication of an AE after any change in study drug, 
the worsening or complication should be recorded as a new AE. Investigators should ensure 
that the AE term recorded captures the change in the condition (eg, “worsening of…”).
Changes in severity of AEs:

If the subject experiences changes in the severity of an AE, the event should be captured once 
with the maximum intensity recorded.
Preplanned procedures (surgeries or interventions):

Preplanned procedures (surgeries or therapies) that were scheduled before signing of informed 
consent are not considered AEs/SAEs. Complications resulting from any planned surgery 
should be reported as AEs.
Elective surgeries or procedures:

Elective procedures performed where there is no change in the subject’s medical condition 
should not be recorded as AEs/SAEs, but should be documented in the subject’s source 
documents. Complications resulting from an elective surgery should be reported as AEs.

TAK-954

Protocol Incorporating Amendment No. 01
28 February 2018
CONFIDENTIAL
Insufficient clinical response (lack of efficacy):

Insufficient clinical response, efficacy, or pharmacologic action, should NOT be recorded as 
an AE. The investigator must make the distinction between exacerbation of pre-existing illness 
and lack of therapeutic efficacy.
Overdose:

Cases of overdose with any study medication without manifested side effects are NOT 
considered AEs, but instead will be documented on an Overdose page of the eCRF. Any 
manifested side effects will be considered AEs and will be recorded on the AE page of the 
eCRF.
10.1.4 SAEs
An SAE is defined as any untoward medical occurrence that at any dose:
1. Results in DEATH.
2. Is LIFE THREATENING.

The term “life threatening” refers to an event in which the subject was at risk of death at the 
time of the event; it does not refer to an event that hypothetically might have caused death 
if it were more severe.
3. Requires inpatient HOSPITALIZATION or prolongation of existing hospitalization.
4. Results in persistent or significant DISABILITY/INCAPACITY.
5. Leads to a CONGENITAL ANOMALY/BIRTH DEFECT.
6. Is an IMPORTANT MEDICAL EVENT assessed by the investigator or the sponsor that 
satisfies any of the following:

May require intervention to prevent items 1 through 5 above.

May expose the subject to danger, even though the event is not immediately life 
threatening or fatal or does not result in hospitalization.

Includes any event or synonym described in the Takeda Medically Significant AE List 
(Table 10.a).

10.1.6 Management of Specific AEs
10.1.6.1 Cardiovascular Disorders
Cardiovascular Events:
Tegaserod, a nonselective 5-HT4 agonist, was withdrawn from the market in 2007 based on pooled 
clinical trial results that suggested increased risk of cardiovascular ischemic events.

TAK-954
Study No. 2002
Page 56 of 95
Protocol Incorporating Amendment No. 01
28 February 2018
CONFIDENTIAL
Suspected cardiovascular events that include ischemic heart disease, cerebrovascular accident (eg, 
transient ischemic attack and stroke), venous or arterial thromboembolic events, and heart failure, 
should be reported as an adverse events of special interest (AESI) to the sponsor within 24 hours 
irrespective of the seriousness. These events will be adjudicated by a cardiovascular endpoint 
committee (CEC) and reviewed by the independent data monitoring committee (IDMC). The 
details will be described in the of the CEC and IDMC charter. 
QT Prolongation
Cisapride, a nonselective 5-HT4 agonist and a potent human ether-à-go-go–related gene blocker, 
was withdrawn from the market due to the risk of prolonged QT interval and sudden death. 
In TAK-954 clinical studies, only 1 subject in Study 0082 had QTcF over 450 msec. This subject 
received TAK-954 0.5 mg IV was in the ICU following an emergency evacuation of a spontaneous 
posterior fossa intraparenchymal hemorrhage. She had medical history of AF on warfarin, mitral 
valve replacement, and biventricular pacemaker, and on Screening, her QTcF was 461 msec. She 
had a maximum QTcF of 496 msec on Day 1 and she was not treated for this finding.
Any QT prolongation event assessed as Grade 2 or worse (QTcF interval longer than 480 msec), 
irrespective of the seriousness, should be reported as an AESI to the sponsor within 24 hours and 
managed according to the following guidelines (Table 10.c). Heart-rate corrected QT interval will 
be calculated using Fridericia’s formula (QTcF=QT/RR1/3).

Concomitant therapies should be reviewed and adjusted as 
appropriate for medications with known QT prolonging effects.
!
If no other cause is identified and the investigator believes it is 
appropriate, particularly if QTcF remains elevated (after the above 
measures have been implemented, or as determined by the 
investigator), study treatment may be interrupted for 1 to 2 days, 
and an ECG should be rechecked regularly.
!
If QTcF has recovered or improved <450 msec and the investigator 
believes it is safe to do so, rechallenge with study treatment should 
be considered after discussion with the medical monitor.
!
ECGs should be conducted at least weekly (eg, at every scheduled 
visit) for 2 weeks following QTcF reduction ≤480 msec.
!
Discontinue treatment with study drug if patient the subject 
develops a second episode of Grade 2 QT prolongation.

Subjects should have continuous cardiac monitoring and be 
discharged only after review by a cardiologist. 
!
Treatment with study treatment should be permanently 
discontinued. 
AV Dissociation/Heart Block
Treatment with study drug should be discontinued with the occurrence of any second or third 
degree heart block and these events should be reported to the sponsor as AESI within 24 hours.
Treatments with study drug may be continued in second degree heart block Mobitz I 
(Wenckebach) after Medical monitor review.

Study drug should be discontinued and the patient managed as per local 
guidelines.
Hypotension
If subjects develop a significant hypotension, which is defined as mean arterial pressure 
<60 mmHg, and no other etiology is identified, treatment with study drug should be interrupted for 
1 to 2 days to manage the hypotension event. If subjects develop a second occurrence of significant 
hypotension and the events is considered related to study drug (ie, no other cause is identified), 
dosing with study treatment should be permanently discontinued.
10.1.6.2 Neurological Disorders
Serotonin Syndrome
Serotonin syndrome, a potentially life threatening adverse drug reaction, may result from drugs 
that increase the serotonergic activity in the central nervous system. The most commonly 
implicated classes of drugs are selective serotonin reuptake inhibitors. The clinical features may

Hypertonia PLUS temperature above 38ºC PLUS ocular clonus or inducible clonus.
Discontinue treatment with study drug. In addition, review the subject medications and 
discontinue any medication(s) that may be associated with serotonin syndrome. Suspected 
serotonin syndrome should be reported to the sponsor as an SAE with 24 hours. 
10.1.6.3 Extrapyramidal Disorder
Acute dystonic reactions occur in approximately 1 in 500 patients treated with the dosages of 30 to 
40 mg/day of metoclopramide. These symptoms may include involuntary movements of limbs and 
facial grimacing, torticollis, oculogyric crisis, rhythmic protrusion of tongue, bulbar type of 
speech, trismus, or dystonic reactions resembling tetanus. Rarely, dystonic reactions may present 
as stridor and dyspnea, possibly due to laryngospasm 
(https://www.accessdata.fda.gov/drugsatfda_docs/label/2010/021793s008lbl.pdf). 
If a subject develops extrapyramidal signs, manage as per table below. Any extrapyramidal 
clinical findings equal to or more than G2 should be reported to the sponsor as an AESI within 
24 hours.


G5: Death.
Diarrhea Grade 3 and above should be reported as AESI to the sponsor within 24 hours.
10.1.6.5 Abnormal LFTs
Treatment with study drug should be discontinued in subjects who develop LFT elevations in the 
following situations: (1) Subjects with ALT <3×ULN at Baseline who develop ALT >3×ULN 
with total bilirubin >2×ULN while on treatment with study drug. 2) Subjects with ALT 3 to 
8×ULN at Baseline who develop a 2-fold increase in ALT over the baseline value while on 
treatment with study drug. Either of these findings should be recorded as a serious AESI and 
reported as per Section 10.2.2. The investigator must contact the medical monitor for discussion of 
the relevant subject details and possible alternative etiologies, such as acute viral hepatitis A or B 
or other acute liver disease or medical history/concurrent medical conditions. In addition, the 
investigator should contact the medical monitor for any increase in LFTs without clear etiology.
Follow-up laboratory tests as described in Section 9.1.9 must also be performed. In addition, an 
LFT Increases eCRF must be completed and transmitted with the Takeda SAE form (as per 
Section 10.2.2). 
In addition, an LFT Increases eCRF must be completed providing additional information on 
relevant recent history, risk factors, clinical signs and symptoms and results of any additional 
diagnostic tests performed.
10.1.6.6 AESI

10.1.7 Causality of AEs
The relationship of each AE to study drugs will be assessed using the following categories:
Related:
An AE that follows a reasonable temporal sequence from administration of a drug (including the 
course after withdrawal of the drug), or for which possible involvement of the drug cannot be 
ruled out, although factors other than the drug, such as underlying diseases, complications, 
concomitant medications and concurrent treatments, may also be responsible.
Not Related:
An AE that does not follow a reasonable temporal sequence from administration of a drug and/or 
that can reasonably be explained by other factors, such as underlying diseases, complications, 
concomitant medications and concurrent treatments.
10.1.8 Relationship to Study Procedures
Relationship (causality) to study procedures should be determined for all AEs.
The relationship should be assessed as Related if the investigator considers that there is reasonable 
possibility that an event is due to a study-specific procedure. Otherwise, the relationship should be 
assessed as Not Related. 
10.1.9 Start Date
The start date of the AE/SAE is the date that the first signs/symptoms were noted by the subject 
and/or investigator.
10.1.10
Stop Date 
The stop date of the AE is the date at which the subject recovered, the event resolved but with 
sequelae or the subject died.
10.1.11
Frequency 
Episodic AEs (eg, vomiting) or those which occur repeatedly over a period of consecutive days are 
intermittent. All other events are continuous.
10.1.12
Action Concerning Study Drug 

Dose interrupted – the dose was interrupted due to the particular AE. Subjects will discontinue 
treatment with study drug if the interruption is more than 2 days.

Drug withdrawn – a study drug is stopped due to the particular AE.

Dose not changed – the particular AE did not require stopping a study drug.

Unknown – only to be used if it has not been possible to determine what action has been taken.

Not applicable – a study drug was stopped for a reason other than the particular AE eg, the 
study has been terminated, the subject died, dosing with study drug was already stopped before 
the onset of the AE.

10.1.13
Outcome

Recovered/resolved – Subject returned to first assessment status with respect to the AE.

Recovering/resolving – the intensity is lowered by 1 or more stages: the diagnosis or 
signs/symptoms has almost disappeared; the abnormal laboratory value improved, but has not 
returned to the normal range or to Baseline; the subject died from a cause other than the 
particular AE with the condition remaining “recovering/resolving”.

Not recovered/not resolved – there is no change in the diagnosis, signs or symptoms; the 
intensity of the diagnosis, signs/ symptoms or laboratory value on the last day of the observed 
study period has got worse than when it started; is an irreversible congenital anomaly; the 
subject died from another cause with the particular AE state remaining “Not recovered/not 
resolved”.

Resolved with sequelae – the subject recovered from an acute AE but was left with 
permanent/significant impairment (eg, recovered from a cardiovascular accident but with 
some persisting paresis.

Fatal – the AEs which are considered as the cause of death. 

Unknown – the course of the AE cannot be followed up due to hospital change or residence 
change at the end of the subject’s participation in the study.
10.2
Procedures
10.2.1 Collection and Reporting of AEs
10.2.1.1 AE Collection Period
Collection of SAEs caused by a protocol-mandated intervention will commence from the time the 
subject signs the informed consent to participate in the study and continue until the subject is first 
administered study drug (Day 1) or until screen failure. 
Collection of AEs will commence from the time that the subject is first administered study drug 
(Day 1). Routine collection of AEs will continue until the Follow-up Visit.
10.2.1.2 AE Reporting
At each study visit, the investigator will assess whether any subjective AEs have occurred. A 
neutral question, such as “How have you been feeling since your last visit?” may be asked. 
Subjects may report AEs occurring at any other time during the study. Subjects experiencing a 
SAE caused by a protocol-mandated intervention must be monitored until the symptoms subside 
and any clinically relevant changes in laboratory values have returned to Baseline or there is a 
satisfactory explanation for the change. 
All subjects experiencing AEs, whether considered associated with the use of the study drug or not, 
must be monitored until the symptoms subside and any clinically relevant changes in laboratory 
values have returned to Baseline or until there is a satisfactory explanation for the changes

the suspected procedure.
7. Action concerning study drug.
8. Outcome of event.
9. Seriousness.
10.2.1.3 AESI
AESI have to be recorded as AEs in the eCRF. An evaluation form along with all other required 
documentation must be submitted to the sponsor.
10.2.2 Collection and Reporting of SAEs
When an SAE occurs through the AE collection period it should be reported according to the 
following procedure:
As soon as an SAE or AESI is entered into the electronic data capture system, an alert is sent to the 
attention of the contact listed in Section 1.1 and to the safety database.
The information should be completed as fully as possible but contain, at a minimum:
A short description of the event and the reason why the event is categorized as serious.

Subject identification number.

Investigator’s name.

Name of the study drug(s).

Causality assessment.
The SAE eCRF should be transmitted within 24 hours of first onset or notification of the event. 
However, as a back-up, if required, the SAE form should be completed and reported to the 
attention of the contact listed in Section 1.1.

Any SAE spontaneously reported to the investigator following the AE collection period should be 
reported to the sponsor if considered related to study participation.
10.3
Follow-up of SAEs
If information not available at the time of the first report becomes available at a later date, the 
investigator should complete a follow-up SAE form or provide other written documentation and
fax it immediately within 24 hours of receipt. Copies of any relevant data from the hospital notes 
(eg, ECGs, laboratory tests, discharge summary, postmortem results) should be sent to the 
addressee, if requested.
All SAEs should be followed up until resolution or permanent outcome of the event. The timelines 
and procedure for follow-up reports are the same as those for the initial report.
10.3.1 Safety Reporting to Investigators, IRBs or IECs, and Regulatory Authorities
The sponsor will be responsible for reporting all suspected unexpected serious adverse reactions 
(SUSARs) and any other applicable SAEs to regulatory authorities, investigators, and IRBs or 
IECs, as applicable, in accordance with national regulations in the countries where the study is 
conducted. Relative to the first awareness of the event by/or further provision to the sponsor or 
sponsor’s designee, SUSARs will be submitted to the regulatory authorities as 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 a study 
drug/sponsor supplied drug or that would be sufficient to consider changes in the study 
drug/sponsor supplied drug administration or in the overall conduct of the trial. The study site also 
will forward a copy of all expedited reports to his or her IRB or IEC.

STUDY-SPECIFIC COMMITTEES
11.1
IDMC
An IDMC will be utilized in TAK-954-2002 for safeguarding the interest of study participants, 
assessing the safety and efficacy of the interventions during the study, and for monitoring the 
overall conduct of the clinical study while maintaining the integrity of the study. The IDMC will 
conduct ongoing review of SAEs, conduct periodic scheduled reviews of safety, and conduct an 
interim review of efficacy and safety data as well as available data from other studies. The IDMC, 
based on these assessments, will provide recommendations as to the adaptive changes specified in 
the protocol: stopping, continuing, or adding a new dose in the study, or sample size modification. 
The IDMC will only advise termination of a dosing group based on safety concerns, overwhelming 
efficacy, or prespecified futility criteria. In order to enhance the integrity of the study, the IDMC 
may also formulate recommendations relating to the selection/recruitment/retention of participants, 
management of the study participants, improving adherence to protocol-specific regimens, and the 
procedures for data management and quality control.
Details of the IDMC, including meeting frequency, will be captured in a charter prior to the start of 
the study.
11.2
Independent CEC
An independent CEC consisting of 2 cardiovascular experts and 1 neurologist will be established 
to prospectively review and adjudicate all suspected cardiovascular events in a blinded fashion to 
determine if the reported event meets the criteria for MACE. The procedures and rules of 
adjudication of these events by the CEC will be described in a separate charter.

DATA HANDLING AND RECORDKEEPING
The full details of procedures for data handling will be documented in the Data Management Plan. 
AEs, medical history, and concurrent medical conditions will be coded using the Medical 
Dictionary for Regulatory Activities (MedDRA). Drugs will be coded using the World Health 
Organization Drug Dictionary.
12.1
eCRFs 
Completed eCRFs are required for each subject who signs an informed consent.
The sponsor or its designee will supply study sites with access to eCRFs. The sponsor will make 
arrangements to train appropriate site staff in the use of the eCRF. These forms are used to transmit 
the information collected in the performance of this study to the sponsor and regulatory authorities. 
eCRFs must be completed in English. Data are transcribed directly onto eCRFs.
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 the sponsor’s 
personnel (or designees) and will be answered by the site. 
Corrections are recorded in an audit trail that captures the old information, the new information, 
identification of the person making the correction, the date the correction was made, and the reason 
for change. Reasons for significant corrections should additionally be included. 
The principal investigator must review the eCRFs for completeness and accuracy and must e-sign 
the appropriate eCRFs as indicated. Furthermore, the investigator must retain full responsibility 
for the accuracy and authenticity of all data entered on the eCRFs.
After the lock of the study database, any change of, modification of or addition to the data on the 
eCRFs should be made by the investigator with use of change and modification records of the 
eCRFs. The principal investigator must review the data change for completeness and accuracy, 
and must sign, or sign and seal, and date.
eCRFs will be reviewed for completeness and acceptability at the study site during periodic visits 
by the sponsor or its designee. 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

STATISTICAL METHODS
13.1
Statistical and Analytical Plans
A statistical analysis plan (SAP) will be prepared and finalized prior to unblinding of subject’s 
treatment assignment. This document will provide further details regarding the definition of 
analysis variables and analysis methodology to address all study objectives.
A blinded data review will be conducted prior to unblinding of subject’s treatment assignment. 
This review will assess the accuracy and completeness of the study database, subject evaluability, 
and appropriateness of the planned statistical methods.
13.1.1 Analysis Sets
The full analysis set (FAS) will include all subjects who were randomized, received at least 1 dose 
of study drug, and have a baseline value and at least 1 valid post-baseline value for assessment of 
primary efficacy. In FAS efficacy summaries, subjects will be analyzed by the treatment to which 
they were randomized.
The per-protocol set (PPS) will include all FAS subjects who had no major protocol violations. If 
more than 5% of the total subjects in the FAS have major protocol violations, analyses based on 
the PPS will be performed for the primary efficacy variable only.
The safety set will include all subjects who have received at least 1 dose of study drug. Subjects in 
this set will be analyzed according to the treatment they actually received. This analysis set will be 
used for safety analyses only.
13.1.2 Analysis of Demographics and Other Baseline Characteristics
Demographic and baseline characteristics will be summarized by each treatment group and overall. 
Summary statistics (N, mean, SD, median, minimum, and maximum) will be generated for 
continuous variables (eg, age and weight) and the number and percentage of subjects within each 
category will be presented for categorical variables (eg, sex, ethnicity, and race). Individual 
subject demographic and baseline characteristics data will be listed.
13.1.3 Efficacy Analysis
Primary Endpoints:
The primary efficacy endpoint will be the average daily protein adequacy received through enteral 
nutrition (defined by % of goal protein delivered per day [% protein goal delivered = actual protein 
achievement / total patient-specific target protein]) over the first 5 days of study treatment.
As subjects remain in the ICU for the study and given the short duration of the assessment period 
the percentage of missing values is not expected to be large. Where subjects have less than five 
days then the average of the available days will be used.
The main analysis of the primary endpoint will use Bayesian methods. A non-informative prior 
distribution for the difference between metoclopramide and each TAK-954 dose will be assumed, 

TAK-954
Study No. 2002
Page 69 of 95
Protocol Incorporating Amendment No. 01
28 February 2018
CONFIDENTIAL
this distribution will be updated using Bayesian methods at two stages. An interim analysis will be 
conducted after approximately 100 subjects (ie, 25 subjects per treatment arm) have completed the 
study. At the interim analysis, the posterior distribution of the difference will be estimated from the 
prior distribution and the study data. The distribution will again be updated at study end when all 
available data will be used to estimate the final posterior distribution for each difference, from 
which 95% credible intervals will be calculated for each TAK-954 dose.
Additionally, an analysis of covariance (ANCOVA) model will be used, with baseline as a 
covariate and treatment and site as a factor. Unadjusted 95% confidence intervals will be 
estimated; additionally, simultaneous 95% confidence intervals of each dose of TAK-954 against 
metoclopramide will also be computed using Dunnett’s method.
The FAS will be the primary population for the analysis of the primary endpoint, with the 
per-protocol population considered as a sensitivity analysis. 
Secondary Endpoints: 
The secondary endpoints, average daily protein adequacy over the study treatment period, average 
daily change in 24 hours GRV over the first 5 days of treatment, and average daily caloric 
adequacy will also be analyzed using ANCOVA.
Time to resolution of EFI will be analyzed using survival analysis methods. Log-rank tests of each 
TAK-954 dose against metoclopramide will be estimated and Kaplan-Meier plots will be 
presented. Additionally, a proportional hazards model may be used to examine the effect of 
covariates, such as site.
The proportion of subjects achieving at least 80% of daily goal calories and maintaining it for at 
least 2 consecutive days and/or the rest of Treatment Period and the proportion of subjects 
achieving at least 80% of daily goal protein and maintain it for at least 2 consecutive days and/or 
the rest of the Treatment Period will each be analyzed using a logistic regression model with 
treatment group and site as factors in the model. Incidence of all-cause mortality up to 30 days 
after the end of treatment will be summarized descriptively.
13.1.4 PK Analysis
No formal PK analyses will be performed on concentration-time data. Summary statistics of 
predose concentrations will be summarized by dose. Individual concentration-time data will be 
included in listings only. 
A more detailed description of these analyses will be given in a separate analysis plan. The results 
from these analyses will not be included in the clinical study report and will be a standalone report.
13.1.5 Safety Analysis
AEs will be summarized using the safety analysis set. 
All AEs will be coded using MedDRA. Data will be summarized using preferred term and primary 
system organ class. The definition of treatment-emergent AEs will be provided in the SAP. AEs 

TAK-954
Study No. 2002

Protocol Incorporating Amendment No. 01

CONFIDENTIAL
will be coded using MedDRA and will be summarized by system organ class and preferred term in 
the core treatment period and entire study.
AEs that were reported more than once by a subject during the same period will be counted only 
once for that subject and period at the maximum severity.
Clinical Evaluations:
Absolute values and changes from Screening/Baseline in clinical safety laboratory tests, vital signs, 
ECG parameters, and weight will be summarized for each treatment group using descriptive 
techniques. Values outside normal ranges and potentially clinically significant values will be 
flagged and tabulated.
13.2
Interim Analysis and Criteria for Early Termination
Interim analysis will be performed after approximately 100 subjects have completed the study (ie, 
25 subjects within each cohort). Efficacy and safety data will be used to determine if stopping 
criteria for individual dose groups are met. Interim decision making for efficacy will be performed 
based on a futility stopping rule. Futility assessments in each dose group will be conducted based 
on the predictive probability of success (PPoS) of the primary efficacy endpoint. 
The criteria for success for each dose group is that posterior probability (standardized treatment 
effect >0.2|Data) > 80% based on the updated distribution of the treatment effect at the end of the 
study. This will be assessed separately for each arm, assuming a positive treatment effect indicates 
improvement. If the PPoS at the interim in a dose group is below a pre-determined threshold (20%), 
2 actions may be taken:

The futility stopping rule will be met and patient enrollment will be discontinued in this dosing 
group. Subjects currently in that dosing group will complete the study receiving that dose if 
safety is not a concern.

Subjects not already randomized will be split equally among any of the remaining dose groups 
after the interim analysis or reassigned to a new dose level.
In addition to the above formal criteria, all available efficacy and safety data from the current study 
and as well as data from the other TAK-954 studies will be used to guide the potential modification 
of design of the study, including dropping of inefficacious dose(s), dropping of doses due to safety 
concerns and inclusion of new dose(s) (less than 1 mg).
13.3
Determination of Sample Size
This study will randomize approximately 200 subjects into 4 treatment groups with an initial equal 
(1:1:1:1) randomization scheme. This sample size is based on simulation of go/no-go decision 
making using a Bayesian approach. If a new dose is introduced after the interim analysis, then the 
randomization scheme may be adjusted to increase the proportion of new subjects being assigned 
to the new dose. Subject randomization will be stratified based on their baseline NUTRIC score 
(either low [0-4] or high [5-9]) to ensure that approximately equal numbers of subjects will be 
randomized into each treatment group from a high or low NUTRIC score group.

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” that are listed in Appendix B. The 
principles of Helsinki are addressed through the protocol and through appendices containing 
requirements for informed consent and investigator responsibilities.
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 guarantees access to source documents by the sponsor or its designee (contract 
research organization) and by the IRB or IEC.
All aspects of the study and its documentation will be subject to review by the sponsor or sponsor’s 
designee (as long as blinding is not jeopardized), including but not limited to the Investigator’s 
Binder, study drug, subject medical records, informed consent documentation, 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. In the event of 
a significant deviation, 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.
The sponsor will assess any protocol deviation; if it is likely to affect to a significant degree the 
safety and rights of a subject or the reliability and robustness of the data generated, it will be 
reported to regulatory authorities as a serious breach of GCP and the protocol.

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 

TAK-954

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 Food and Drug Administration [FDA], the United Kingdom 
Medicines and Healthcare products Regulatory Agency). If the study site is contacted for an 
inspection by a regulatory body, the sponsor should be notified immediately. The investigator 
guarantees access for quality assurance auditors to all study documents as described in 
Section 14.1.
14.4
IRB and/or IEC Approval
IRBs and IECs must be constituted according to the applicable state and federal/local requirements 
of each participating region. The sponsor or designee will require documentation noting all names 
and titles of members who make up the respective IRB or IEC. If any member of the IRB or IEC 
has direct participation in this study, written notification regarding his or her abstinence from 
voting must also be obtained. Those Americas sites unwilling to provide names and titles of all 
members due to privacy and conflict of interest concerns should instead provide a Federal Wide 
Assurance Number or comparable number assigned by the Department of Health and Human 
Services.
The sponsor or designee will supply relevant documents for submission to the respective IRB or 
IEC for the protocol’s review and approval. This protocol, the Investigator’s Brochure, a copy of 
the informed consent form, and, if applicable, subject recruitment materials and/or advertisements 
and other documents required by all applicable laws and regulations, must be submitted to a 
central or local IRB or IEC for approval. The IRB’s or IEC’s written approval of the protocol and 
subject informed consent must be obtained and submitted to the sponsor or designee before 
commencement of the study. The IRB or IEC approval must refer to the study by exact protocol 
title, number, and version date; identify versions of other documents (eg, informed consent form) 
reviewed; and state the approval date. The sponsor will ship drug and/or notify site once the 
sponsor has confirmed the adequacy of site regulatory documentation. Until the site receives 
notification no protocol activities, including Screening may occur.
Study sites must adhere to all requirements stipulated by their respective IRB or IEC. This may 
include notification to the IRB or IEC regarding protocol amendments, updates to the informed 
consent form, 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 informed consent form, subject authorization form and 
subject information sheet (if applicable) describe the planned and permitted uses, transfers, and 
disclosures of the subject’s personal health information for purposes of conducting the study. The 
informed consent form and the subject information sheet (if applicable) further explain the nature 
of the study, its objectives, and potential risks and benefits, as well as the date informed consent is 
given. The informed consent form will detail the requirements of the participant and the fact that 
he 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 
informed consent form and the subject authorization form. The informed consent form, subject 
authorization form, and subject information sheet (if applicable) must be approved by both the IRB 
or IEC and the sponsor prior to use.
The informed consent form, subject authorization form and subject information sheet (if 
applicable) must be written in a language fully comprehensible to the prospective subject or their 
LAR. It is the responsibility of the investigator to explain the detailed elements of the informed 
consent form, subject authorization form (if applicable), and subject information sheet (if 
applicable) to the subject. Information should be given in both oral and written form whenever 
possible and in the manner deemed appropriate by the IRB or IEC. In the event the subject is not 
capable of rendering adequate written informed consent, then the subject’s LAR may provide such 
consent for the subject in accordance with applicable laws and regulations.
The subject, or the subject’s LAR, 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 
LAR, determines he or she will participate in the study, then the informed consent form and 
subject authorization form must be signed and dated by the subject, or the subject’s LAR, at the 
time of consent and prior to the subject entering into the study. The subject or the subject’s LAR 
should be instructed to sign using their legal names, not nicknames, using blue or black ballpoint 
ink. The investigator must also sign and date the informed consent form and subject authorization 
at the time of consent and prior to subject entering into the study; however, the sponsor may allow 
a designee of the investigator to sign to the extent permitted by applicable law.
Once signed, the original informed consent form, subject authorization form 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 and subject 
information sheet (if applicable) shall be given to the subject or their LAR.
All revised informed consent forms must be reviewed and signed by relevant subjects or the 
relevant subject’s LAR in the same manner as the original informed consent. The date the revised 

TAK-954

consent was obtained should be recorded in the subject’s medical record, and the subject or their 
LAR should receive a copy of the revised informed consent form.
14.6
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 trial database or documentation via a subject 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 the monitor or the sponsor’s designee, representatives from any 
regulatory authority (eg, FDA, Medicines and Healthcare products Regulatory Agency, 
Pharmaceuticals and Medical Devices Agency), the sponsor’s designated auditors, and the 
appropriate IRBs and IECs to review the subject’s original medical records (source data or 
documents), including, but not limited to, laboratory test result reports, ECG reports, admission 
and discharge summaries for hospital admissions occurring during a subject’s study participation, 
and autopsy reports. Access to a subject’s original medical records requires the specific 
authorization of the subject as part of the informed consent process (see Section 14.5).
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 eCRF).
14.7
Publication, Disclosure, and Clinical Trial Registration Policy
14.7.1 Publication and Disclosure
The investigator is obliged to provide the sponsor with complete test results and all data derived by 
the investigator from the study. During and after the study, only the sponsor may make study 
information available to other study investigators or to regulatory agencies, except as required by 
law or regulation. Except as otherwise allowable in the 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 study site agreement. In the event of any discrepancy between the protocol and 
the study site agreement, the study site agreement will prevail.
The investigator needs to obtain a prior written approval from the sponsor to publish any 
information from the study externally such as to a professional association.

14.7.2 Clinical Trial Registration
In order to ensure that information on clinical trials reaches the public in a timely manner and to 
comply with applicable laws, regulations and guidance, the sponsor will, at a minimum register all 
interventional clinical trials it sponsors anywhere in the world on ClinicalTrials.gov and/or other 
publicly accessible websites before start of study, as defined in Takeda Policy/Standard. Takeda 
contact information, along with investigator’s city, state (for American investigators), country, and 
recruiting status will be registered and available for public viewing. 
For some registries, Takeda will assist callers in locating study sites closest to their homes by 
providing the investigator name, address, and phone number to the callers requesting trial 
information. Once subjects receive investigator contact information, they may call the site 
requesting enrollment into the trial. The investigative sites are encouraged to handle the trial 
inquiries according to their established subject screening process. If the caller asks additional 
questions beyond the topic of trial enrollment, they should be referred to the sponsor.
Any investigator who objects to the sponsor providing this information to callers must provide the 
sponsor with a written notice requesting that their information not be listed on the registry site. 
14.7.3 Clinical Trial Results Disclosure
The sponsor will post the results of clinical trials on ClinicalTrials.gov and/or other publicly 
accessible websites, as required by Takeda Policy/Standard, applicable laws and/or regulations.
14.8
Insurance and Compensation for Injury
Each subject in the study must be insured in accordance with the regulations applicable to the site 
where the subject is participating. If a local underwriter is required, then the sponsor or sponsor’s 
designee will obtain clinical study insurance against the risk of injury to study subjects. Refer to 
the study site agreement regarding the sponsor’s policy on subject compensation and treatment for 
injury. If the investigator has questions regarding this policy, he or she should contact the sponsor 
or sponsor’s designee.

(a) The dose is to be given within 6 hours of randomization.
(b) NUTRIC score variables include age, APACHE II, SOFA, number of comorbidies, and days from hospitalization to ICU admission.
(c) A neurological examination will be conducted at Baseline, on Days 2, 5, 8, and 12 while subjects are receiving study drug, and at 3 days following last dose.
(d) Vital signs will be collected 30 minutes prior to the start of the infusion, 30 minutes after the infusion starts and at the end of the infusion. Temperature will only 
be collected at the start of the infusion. Blood pressure and heart rate will be captured every 4 hours for the first 48 hours after the first dose of study drug. 
(e) Height will only be collected at Baseline. BMI will be derived.
(f) Concomitant medications will be collected from the signing of the informed consent through 3 days after the last dose of study medication (inclusive).
(g) 12-lead ECG will be performed before the 60 minute IV infusion on Day 1 (Baseline); approximately 1, 2, and 8 hours after the start of the 60 minute IV infusion 
on Days 1 and 2; at the end of the infusion (approximately 1 hour after the start of the infusion) on every other day of treatment, and at the end of the infusion 
(approximately 1 hour after the start of the 60 minute IV infusion) on the last day of study drug. In addition, a 12-lead ECG will be performed when needed, if a 
subject develops symptoms suggestive of cardiovascular origin (eg, dizziness, chest pain). 
(h) Holter Monitoring is ONLY required for the first 24 to 48 hours following the start of study infusion for approximately 10 subjects per arm in a subset of sites.
(i) Sodium, potassium, bicarbonate, glucose, blood urea nitrogen, creatinine, hematology, total bilirubin, alkaline phosphatase, ALT, AST, and GGT will be done at 
Screening, Baseline, Days 2, 3, 5, and every other day until the last day of study drug, and 3 days after the last day of study drug. For both hematology and chemistry 
values, if labs are done on that calendar day for routine clinical care, they will not be drawn additionally for the study on that day. No laboratory tests are needed at 
Baseline if the interval between Screening and Baseline is less than 24 hours. 
(j) A PK sample will be obtained at 0 (predose) and 1 (just after the end of the infusion) hour on Days 1, 5, and last day of dosing. An additional 3 PK samples after

Appendix B
Responsibilities of the Investigator
Clinical research studies sponsored by the sponsor are subject to ICH GCP and all the applicable 
local laws and regulations. The responsibilities imposed on investigators by the FDA are 
summarized in the “Statement of Investigator” (Form FDA 1572), which must be completed and 
signed before the investigator may participate in this study.
The investigator agrees to assume the following responsibilities by signing a Form FDA 1572:
1. Conduct the study in accordance with the protocol.
2. Personally conduct or supervise the staff who will assist in the protocol.
3. Ensure that study related procedures, including study specific (nonroutine/nonstandard panel) 
Screening assessments are NOT performed on potential subjects, prior to the receipt of written 
approval from relevant governing bodies/authorities.
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. Ensure that valid informed consent has been obtained for each subject who participates in the 
study, and document the date of consent in the subject’s medical chart. Valid informed consent 
is the most current version approved by the IRB/IEC. Each informed consent form should 
contain a subject authorization section that describes the uses and disclosures of a subject’s 
personal information (including personal health information) that will take place in connection 
with the study. If an informed consent form does not include such a subject authorization, then 
the investigator must obtain a separate subject authorization form from each subject or the 
subject’s legally acceptable representative.
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.
10. Allow possible inspection and copying by the regulatory authority of GCP-specified essential 
documents.
