Brief summary:
Botulinum toxin A (GSK1358820) is a sterile, purified type A botulinum neurotoxin complex. In Japan, 240 units of botulinum toxin A are approved as a maximum dose per administration for upper limb spasticity. This study is planned to evaluate the effectiveness and safety of 400 units of botulinum toxin A which can help to increase the maximum dose per administration to 400 units from 240 units as the treatment with 240 units is considered insufficient in subjects with post-stroke upper limb spasticity. Approximately 120 subjects will be randomized to receive either 400 or 240 units of botulinum toxin A in double blind phase followed by open-label phase in which 400 units of the study treatment will be injected in both the groups. The study period will be up to 52 weeks, consisting of a screening phase up to 4 weeks, minimum 12-week double blind phase (Part 1), maximum 36- week open-label phase (12 weeks per cycle with 3 treatment phases: Part 2, Part 3 and Part 4).

Detailed description:

Arms:
arm 1: Subjects will receive a total dose of 400 units of botulinum toxin A of which 240 units will be injected into the muscles that act on finger (including thumb flexors) and wrist flexors, and a total of 160 units will be injected into the muscles that act on the elbow flexors. arm 2: Subjects will receive 240 units of botulinum toxin A injected into the muscles that act on the finger (including thumb flexors) and wrist flexors. Placebo will be injected into the muscles that act on the elbow flexors. arm 3: Subjects will receive botulinum toxin A with a dose of 400 units injected in a divided doses.

Interventions: intervention 1: Botulinum toxin A (GSK1358820) intervention 2: Placebo
Intervention descriptions: intervention 1: GSK1358820 is sterile, purified type A botulinum neurotoxin complex. GSK1358820 injection will contain botulinum toxin A (100 units), sodium chloride (0.9 milligrams \[mg\]), and human serum albumin (0.5 mg). It will be available with doses of 400 units and 240 units. intervention 2: Placebo injection will contain sodium chloride (0.9 mg).

SYNOPSIS
Protocol Title: A phase III study (a placebo controlled, randomized, double-blind comparative study 
and an open-label, uncontrolled study) to evaluate the efficacy and safety of GSK1358820 in patients 
with post-stroke upper limb spasticity
Short Title: A phase III study to evaluate the efficacy and safety of GSK1358820 in patients with 
post-stroke upper limb spasticity
Rationale:
GSK1358820, botulinum toxin type A (hereafter referred as the product), is sterile, purified type A 
botulinum neurotoxin complex. Intramuscularly injected botulinum neurotoxin shows muscle relaxant 
effects by blocking the neuromuscular junction and inhibiting release of acetylcholine, a 
neurotransmitter. Since the approval of the product for strabismus and blepharospasm in US in 1989, 
the product is licensed for the treatment of various diseases, which respond to the muscle relaxant 
effects in more than 90 countries (as of Apr 2017).
In Japan, the product is licensed with 8 indications as an ethical drug so far: blepharospasm as a 
first indication in Oct 1996, followed by “hemifacial spasm” in Jan 2000, “spasmodic torticollis” in 
Jun 2001, “talipes equinus associated with lower limb spasticity in pediatric patients two years of age 
and older with cerebral palsy” in Feb 2009, “upper limb spasticity” and “lower limb spasticity” in Oct 
2010, “severe primary maschalephidrosis” in Nov 2012, and “strabismus” in Jun 2015. For “upper 
limb spasticity,” 240 units of the product is approved as a maximum dose per administration. In US, 
as a maximum dose per administration, 400 units of injection of the product have been approved for 
the treatment of upper limb spasticity in adult patients in 2015; therefore, the authorized dose of the 
product between US and Japan is different.
This study is a multicenter, double blind, placebo controlled phase III domestic study and aims to 
evaluate the efficacy and safety of 400 units of the product in patents with post-stroke upper limb 
spasticity. The study was planned to increase the maximum dose per administration in Japan to 400 
units from 240 because the treatment with 240 units of the product, a maximum dose per 
administration, is considered to be insufficient in some patients with post-stroke upper limb spasticity.

Number of Participants:
Approximately 120 subjects (approximately 60 in each group) will be randomized to obtain an 
evaluable subject sample of approximately 100 at Week 48 as subjects with completion of the study。
Treatment Groups and Duration:
Screening Phase (Day -28～Day -1)
Evaluation and screening tests will be performed 28 to 7 days (±3days) before initial injection 
(Day 1) as a starting point. The investigator will decide which arm to be injected during screening 
phase.
Blind Phase (minimum 12 Weeks): Placebo Controlled, Randomized, Double Blind 
Design
Subjects wkho meet the inclusion criteria will be randomly assigned 1:1 to either the 400 or the 240 
units group. 

In the 400 units group, a total of 240 units of the product will be injected into the muscles 
that act on the finger (including thumb flexors) and wrist flexors, and a total of 160 units 
into the muscles that act on the elbow flexors; a total of 400 units of the product will be 
injected.

In the 240 units group, a total of 240 units of the product will be injected into the muscles 
that act on the finger (including thumb flexors) and wrist flexors. Placebo will be injected 
into the muscles that act on the elbow flexors. A total of 240 units of the product will be 
injected.

CONFIDENTIAL
207660
If the total dose for the muscles that act on the finger and writs flexors is ensured by 240 units, and 
160 units for the muscles that act on the elbow flexors, the dose can be adjusted at a investigator’s 
discretion based on the subject’s symptoms.
Open-Label Phase (maximum 36 Weeks): Uncontrolled, Open-Label Design
The product of 400 units will be injected in both groups. The product can be injected up to 3 times 
after completion of Part 1 in the blind phase. In the open-label phase, subjects whom the investigator
considers eligible for the injections will be treated. The next injections cannot be performed until the 
eligibility of the subject has been confirmed by the investigator. 
In the open-label phase, the muscle to be injected and the dose will be decided by the investigator 
based on the patient’s symptoms, and a total dose of 400 units of the product will be injected in a 
divided dose. For the muscles that the investigator considers unnecessary to be treated, an injection 
may be skipped. The involving muscle and the dose do not have to be same each time always.
Injection Criteria in and after Part 2 in the Open-Label Phase
In the open-label phase (Part 2, Part 3, and Part 4), only the subjects whom the investigator 
considers eligible for the study will be injected. The eligibility is evaluated at a study visit after Week 
12 (V5. If a subject does not meet the criteria at V5, the eligibility is evaluated at QRV (Qualification 
for Retreatment Visit). Subjects are considered to be eligible if following criteria are all satisfied:

a.
Test items for screening must be performed 1 weeks before Day 1 visit (±3 days).
b.
Eligibility evaluation (Qualification for Retreatment Visit: QRV) will be performed at V5 as a starting point if a subject does not meet the criteria only. The evaluation is performed at a 4-week interval, 
V5 as a starting point, The QRV when a subject meets the criteria will be a same day as the injection in the next treatment period (refer to Figure 1, Figure 2, Figure 3, Figure 4). 
c.
If a subject is evaluated to meet the eligibility for the injection in the blind phase at V5, the subject will move forward to Part 2 in the open-label phase (Namely, V5 in Part 1 and V1 in Part 2 is a same 
day). If the subject does not meet the eligibility, QRV will be performed 4 weeks later, at V5 as s starting point. 
d.
If a subject is evaluated to meet the eligibility at V5 in the open-label phase, the subject will move forward to the next treatment phase (V5 and V1 in the next treatment phase is a same day). If the 
subject does not meet the eligibility, QRV is performed 4 weeks later, V5 as a starting point. If V5 in Part 4 is at Week 48 after initial injection, V5 will be considered to be completion visit (FV).
However, for the testing items, pre-scheduled tests at V5 and neutralizing antibody tests will be performed. If V5 in Parts 2 and 3 is performed at Week 36 or later, after completion of V5, completion 
visit will be performed at Week 48.
e.
QRV is allowable to perform from initial injection to Week 36. Eligibility evaluation (QRV) will not be performed after Week 36.  
f.
V5 must be performed at least 84 days after V1. 
g.
The acceptable visit windows will be -14 to +4 days if QRV is performed at Week 36.
h.
Must be performed earlier than any other procedures
i.
Must be performed before injection of the product
j.
For inclusion/exclusion criteria, the items to be observed are different between screening phase and Day 1. For details, refer to 6.1. and 6.2.
k.

INTRODUCTION 
3.1.
Study Rationale
GSK1358820, botulinum toxin type A (hereafter referred to as the product) is sterile, purified type 
A botulinum neurotoxin complex. Intramuscularly injected botulinum neurotoxin shows muscle 
relaxant effects by blocking the neuromuscular junction and inhibiting the release of acetylcholine, a 
neurotransmitter. Since the approval of the product for strabismus and blepharospasm in US in 1989, 
the product is licensed for the treatment of various diseases, which respond to the muscle relaxant 
effects in more than 90 countries (as of Apr 2017). 
In Japan, the product is licensed with 8 indications as an ethical drug so far: blepharospasm as first 
indication in Oct 1996, followed by “hemifacial spasm” in Jan 2000, “spasmodic torticollis” in Jun 
2001, “talipes equinus associated with lower limb spasticity in paediatric patients two years of age and 
older with cerebral palsy” in Feb 2009, “upper limb spasticity” and “lower limb spasticity” in Oct 
2010, “severe primary maschalephidrosis” in Nov 2012, and “strabismus” in Jun 2015. For “upper 
limb spasticity,” 240 units of the product is approved as a maximum dose per administration. 
This study is a multicenter, double blind, placebo controlled phase III domestic study in patients 
with upper limb spasticity and aims to confirm the efficacy and safety of 240 units of the product for 
post-stroke upper limb spasticity. The information of 400 units of the product in the study is expected 
to provide beneficial information because the treatment with 240 units of the product with a maximum 
dose per administration is considered to be insufficient in some patients with post-stroke upper limb 
spasticity.
3.2.
Background
Spasticity is a movement disorder that is characterized by increased myotatic reflex and is regarded 
as one of positive signs of the upper motor neuron signs (Kagamihara, 2012; Lance, 1980). Spasticity 
is caused by central nerve system injuries such as stroke, traumatic brain injury, or spinal cord injury 
and chronic neuropathies such as cerebral palsy or multiple sclerosis, etc. Abnormal postures of the 
upper limbs due to spasticity include thumb refraction, a clenched fist deformity, flexion of the wrist 
flexors, pronation of the forearms, flexion of the elbow flexors, and adduction/inner rotation of the 
shoulder flexors (Gracies, 2003; Kinoshita, 2015). 
Spasticity hampers rehabilitation therapy. In addition, limitation of flexors range of motion and 
persistent pain hinder from caregiving and decrease activity in daily life (Grazko, 1995); therefore, 
many of patients with stroke require treatments to ameliorate their dysfunction.
For the treatments of spasticity, rehabilitation therapy, oral medications, phenol blocks, and 
baclofen injections were used until botulinum therapy has been approved as a national health 
insurance coverage. These treatments were commonly challenging because of lack of effects, difficult 
procedures, or invasive interventions. Subsequently, in Oct 2010, the product was approved as a 
botulinum treatment for upper and lower limb spasticity in Japan. Since then, botulinum toxin has 
been used for the treatment of spasticity (Ohsawa, 2013). According to the “Japanese Guidelines for 
the Management of Stroke” (initial version in 2009, revised in 2015) (Ogawa, 2015; Shinohara, 2009), 
which was issued by the Japan Stroke Society, botulinum therapy is recommended for the treatment of 
spasticity as Grade A, and is considered to be effective for relief of upper limb spasticity, increase of 
range of motions in flexors, and reduction of the amount of assistance on daily life.

In Japan, upper limb spasticity, a domestic phase II study involving the finger, wrist, and elbow 
flexors was performed from Dec 2001 through Mar 2003, and a domestic phase III study involving the 
finger and wrist flexors from May 2007 through Dec 2008. Consequently, the product was approved 
for the treatment of upper limb spasticity with a maximum dose of 240 units per administration in Oct 
2010. 
However, subsequently, the injections of the product at 240 units were found to be insufficient for 
the involving muscles because patients with extensive upper limb spasticity require dose adequate to 
inject into many of the involving muscles. Therefore, many medical institutions requested us to 
increase the maximum dose per administration of the product. Moreover, the specified drug-use 
survey from Jun 2011 through Apr 2014 identified that approximately 39% of the patients who use the 
product for upper limb spasticity were injected more than 240 units, a maximum dose per 
administration. The results suggest high patient needs for an increase of the maximum dose per 
administration of the product. 
In US, as a maximum dose per administration, 400 units of injections of the product have been 
approved for the treatment of upper limb spasticity in adult patients in 2015; therefore, the authorized 
dose between US and Japan is different. 
Based on these background, the study was planned to evaluate the efficacy and safety of 400 units 
of the product for upper limb spasticity in order to increase the maximum dose per administration to 
400 units. 
The study was planned based on the regulatory advice by the Pharmaceuticals and Medical Devices 
Agency (PMDA).

Measures for risk minimization
Investigational product :GSK1358820
Hypersensitivity
Serious and/or immediate hypersensitivity reactions
(anaphylaxis, serum sickness, urticarial, soft tissue 
edema, or dyspnea, etc.) have been rarely reported. 
Patients who previously experienced allergic reactions 
due to botulinum toxin type A, an additive agent of 
sodium chloride, or human serum albumin are 
excluded from enrolment. Upon written informed 
consent process, subjects will be explained that any 
urticarial, swelling face, throat swelling, wheezing, 
dizziness, or dyspnoea should contact their 
investigator. 
Pre-existing neuromuscular disorder
Patients with neuromuscular junction diseases 
(myasthenia gravis, Lambert-Eaton myasthenic 
syndrome etc.) may increase the sensitivity to the 
product, resulting in excessive muscular weakness. 
For patients with myasthenia gravis, Eaton-Lambert 
syndrome (ELS), amyotrophic lateral sclerosis, or a 
serious disease and who use a concomitant drug (s) 
which may inhibit neuromuscular function, exclusion 
criteria will be set, and those patients will be excluded 
from enrolment in the study (refer to 6.2.1). 
distant spread of toxin
Adverse drug reactions in the remote muscles, except 
but the injected site, have been rarely reported. The 
adverse drug reactions include muscular weakness, 
constipation, dysuria, swallowing difficult, and non-
accidental entering of food or fluid in the lungs not via 
the stomach, but the trachea (pneumonia may occur). 
The patients who received the product at a higher dose 
are considered likely to have increased risks for these 
adverse drug reactions. 
In this study, a high dose of 400 units of the product 
will be injected. Therefore, the subjects will be 
followed up after 2, 4, 6, and 12 weeks of injection. 
The safety of the subjects will be observed carefully.
Use of at least one of the following guide tools 
(electromyogram, electrical stimulator, or 
ultrasonography) will be essential in the blind phase to 
ensure identification of the exact site of injection.

Important identified risks
Reports suggesting risks/ Outlines of rationale
Measures for risk minimization
Immunogenicity, drug resistance, antibody production The important cause of neutralizing antibody 
production has not been fully clarified. A few studies 
suggested that the injection of the product at short 
intervals or at a high dose may lead to increased rate 
of antibody production[Jankovic, 2006; Klein, 2002]. 
Neutralizing antibody production against botulinum 
toxin type A may lead to inactivation of the biological 
activity of the product, resulting in decreased 
therapeutic effects of the product.
In this study, patients who were considered likely to 
have neutralizing antibody production based on the 
previous treatment experience of botulinum toxin type 
A will be excluded from enrolment in the study 
(Exclusion Criteria 6.2.1).
In addition, treatment schedule in the study was set to 
ensure at least a 12-week dosing interval. 
Other (If applicable)
Medication error (preparation with lidocaine)
One fatal case due to anaphylaxis has been reported. 
In this case, the patient died after 100 units of an 
injection of the product that prepared inappropriately 
with 5 mL of 1% lidocaine. The causal relationship of 
death to the product and lidocaine, or both has been 
unknown. 
In this study, the product will be prepared
appropriately with 0.9% normal saline. The 
preparation method will be described on the study 
reference manual (SRM).

3.3.2.
Benefit Assessment
In patients with post-stroke upper limb spasticity, currently, the product is approved to inject up to 
240 units per administration in Japan. However, in patients with extensive upper limb spasticity, the 
treatment effects of the product is presumed to lack because of the dose limitation.
In US, the efficacy and safety of the product up to 400 units per dose for patients with upper limb 
spasticity is confirmed, and the clinical use of the product has been approved. The injections of 400 
units of the product in this study are expected to increase injectable sites and enhance the treatment 
effects in Japanese patients with upper limb spasticity, who did not have great benefits from 240 units 
of the product.
If a subject is assigned to the 240 units group in Part 1 and meets the eligibility criteria for injection in 
the open-label phase, 400 units of the product will be injected in and after Part 2. Therefore, all the 
subjects who participate in this study are given the opportunity to receive 400 units of the product 
(Refer to “5. STUDY DESIGN”). 
3.3.3.
Overall Benefit:Risk Conclusion
The known potential risks in the product is justified by the benefits which would provide for the 
patients with post-stroke upper limb spasticity, given the safety measures to minimize risks in subjects 
who enrol in the study.

Figure 5   Study Design
In this study, the efficacy of 400 units of the product at Week 6 is evaluated, comparing to that of 
240 units, and improvement tendencies are also evaluated in patients with post-stroke upper limb 
spasticity. The improvement will be defined as at least 1 reduction on the MAS score from baseline (a 
measurement value before injection of Day 1). The responder rate (the rate of the subjects that MAS 
score is reduced at least 1 from baseline) in the elbow flexors at Week 6 is set as an endpoint. As a 
point estimate, if the responder rate in the 400 units group outweighs that in the 240 units group, 
improvements tendencies will be considered to be positive. 
For injection, use of the following any one of the tools: EMG, electrical stimulator, or 
ultrasonography, is recommended to ensure identification of the exact injection site. In the blind phase, 
use of at least one of the following tools: EMG, electrical stimulator, or ultrasonography, will be 
essential to ensure identification of the muscle to be injected correctly. 
5.1.1.
Screening Phase (up to 4 weeks) 
Evaluation and screening tests will be performed 28 days to 7 days (+3 days) before initial injection 
(Day 1) as a starting point. The investigator will decide which arm to be injected during screening 
phase. Throughout the study period, the arm, which is decided to be injected at screening phase will 
be involved during the injections and evaluations, unless clearly specified otherwise by the sponsor.

5.1.2.
Blind Period (minimum 12 Weeks): Placebo Controlled, Randomized, Double 
Blind Design
Subjects who meet the inclusion criteria will be randomized 1:1 to either the 400 units or the 240 
units group. 

In the 400 units group, a total of 240 units of the product will be injected into the muscles 
that act on the finger (including thumb flexors) and wrist flexors, and a total of 160 units 
into the muscles that act on the elbow flexors; a total of 400 units of the product will be 
injected.

In the 240 units group, a total of 240 units of the product will be injected into the muscles 
that act on the finger (including thumb flexors) and wrist flexors. Placebo will be injected 
into the muscles that act on the elbow flexors. A total of 240 units of the product will be 
injected.
If the total dose for the muscles that act on the finger and writs flexors is ensured by 240 units, and 
160 units for the muscles that act on the elbow flexors, the dose can be adjusted at a investigator’s 
discretion based on the subject’s symptoms. (Refer to “7.1. Treatments Administered” Table 2).
5.1.3.
Open-Label Phase (maximum 36 weeks): Uncontrolled, Open-Label Design
The product of 400 units will be injected in both groups. The product can be injected up to 3 times 
after completion of Part 1 in the blind phase. In the open-label phase, subjects whom the investigator 
considers eligible for the injection will be treated (Refer to 5.1.3.1. Eligibility Criteria for Injection in 
and after Part 2). The next injection cannot be performed until the eligibility of the subject has been 
confirmed by the investigator (Refer to 5.1.3.1. Eligibility Criteria for Injection in and after Part 2).
In the open-label phase, the muscle to be injected and the dose will be decided by the investigator
based on the patient’s symptoms, and a total dose of 400 units of the product will be injected in a 
divided dose (Refer to "7.1. Treatments Administered” on Table 3). For the muscles that the 
investigator considers unnecessary to be treated, an injection may be skipped. The involving muscle 
and the dose do not have to be same each time always.
5.1.3.1.
Eligibility Criteria for Injection in and after Part 2
In the open-label phase (Part 2, Part 3, and Part 4), the subjects whom the investigator considers
eligible for the injections in the open-label phase only will be treated. The eligibility is evaluated at a 
study visit after Week 12 (V5, if a subject does not meet the eligibility criteria, the evaluation will be 
performed at QRV (Qualification for Retreatment Visit). A subject will be considered as eligible when 
he or she meets all the criteria. The eligibility evaluation will be performed after completion of Part 1 
in the blind phase, between Week 12 to Week 36. If a subject does not meet the eligibility at Week 36, 
subsequent evaluation will not be performed, and the product cannot be given (refer to Figure 1, 
Figure 2, Figure 3, and Figure 4).

The study design was set to evaluate the efficacy and safety of 400 units of the product in patients 
with post-stroke upper limb spasticity. The primary endpoints employed the responder rate of the 
MAS score in the elbow flexors. The reasons for employing MAS score as an indicator include that 
MAS is highly reliable for evaluation of upper limb spasticity (Bohannon, 1987; Mutlu, 2008); 
especially, for evaluation of spasticity in the elbow flexors in the upper limbs (Gregson, 2000; Sloan, 
1992). 
Screening Phase
The screening phase up to 28 days before initial injection was set in order to confirm subjects meet 
the inclusion criteria and none of the exclusion criteria, and assess the condition of subjects at baseline. 
However, measurements of laboratory parameters at screening phase should be completed by 4 days 
before Day 1 (Day -28 to -4).

Treatment Phase 
In Part 1, a double blind comparative study was set to compare the efficacy of the product of 400 
units to 240 units, the currently approved dose for upper limb spasticity. In the blind phase, 240 units 
of the product will be injected into the muscles that act on the finger (including the thumb)/wrist 
flexors, and 160 units (the 400 units group) or placebo (the 240 units group) for the muscles that act 
on the elbow flexors. The improvement tendencies in the efficacy between the 240 units group, the 
total dose, and the 400 units groups will be compared by evaluating the responder rate tendencies on 
the MAS score in the elbow flexors in a blinded manner. In the previous confirmatory study (108509 
study) for approval of the product for upper limb spasticity, the elbow flexors were not involved. 
Therefore, in this study, the responder rate on the MAS score in the elbow flexors was decided to 
compare as the placebo group. 
Actually, in medical institutions, the product is injected into the whole upper limb, including the 
shoulder flexors. In addition, the dose for each muscle is decided at a investigator’s discretion. 
Previous studies reported that botulinum injections into the pectoralis major and teres major muscle 
relieved pain in patients with hemiplegia (Marciniak, 2012) and injections into the sub-scapula 
improved passive range of motion (Yelnik, 2007). Therefore, in and after Part 2 in the open-label 
phase, the product will be allowed to be injected not only into the muscles that acts to the finger 
(including the thumb), wrist, and elbow flexors, but also the muscles that act on the shoulder flexors, 
where applicable, enabling a investigator to decide the dose for each muscle. In addition, the study 
design included safety evaluation of the product at Week 48 after initial injection in all subjects as far 
as possible for safety evaluation purposes of 400 units. 
5.5.
Dose Justification
The product of 400 units is a maximum dose for upper limb spasticity, which was approved by the 
U.S. Food and Drug Administration (FDA), and this suggests that the efficacy and safety profiles are 
favourable. Evaluation of the efficacy and safety of 400 units of the product provides beneficial 
information in Japanese patients with severe post-stroke upper limb spasticity, who are considered 
injections of 400 units of the product are necessary. 
The dose of 240 units of the product, the controlled group, in the blind phase (Part 1) is the current 
authorized dose (a maximum dose per administration) for upper limb spasticity in Japan. In this study, 
the 240 units group was set as the control group in order to evaluate improvement tendencies, 
comparing the efficacy of 240 units of the product, the current approved dose, to that of 400 units of 
the product.

Method of Treatment Assignment
After completion of all evaluations at screening phase/initiation of the blind phase, the subjects who 
met the inclusion criteria and none of the exclusion criteria will be given their randomization number
at a case registry center and randomized to either the 240 or 400 units group. The assigned 
randomization number cannot be re-used. The table of the allocation will be prepared via a computer 
in GSK, using the RandAll systems. 
Based on the MAS score (3 or 4) in the elbow flexors, subjects will be stratified at the time of 
randomization. 
The subjects who meet the eligibility for the injections in the open-label phase can move forward to 
the open-label phase and be injected (Refer to section 5.1.3). In the open-label phase, 400 units of the 
product will be given to all subjects. Other detailed information will be described on SRM.
7.4.
Blinding
This study consists of the blind phase (Part 1), followed by the open-label phase (Part 2 and 
subsequent Parts), and in the blind phase, following processes are applied. 
A Role of the Person Responsible for Investigational Product Assignment  
The person who is responsible for investigational product assignment will prepare an operating 
procedure for the assignment. The operation will be conducted in accordance with the operating 
procedure. The person who is responsible for the investigational product assignment will display the 
drug number on a container of the investigational product (investigational product and control drug)

after checking of the investigational product (investigational product and control drug) and the 
indistinguishability of packaging appearance. The confirmation of the investigational product 
(investigational product and control drug) and the indistinguishability of packaging appearance will be 
also performed after completion of the study. In addition, an operating procedure for occasion where 
the emergency treatment disclosure is required will be prepared. In response to the request of 
disclosure, unblinding procedures are performed for the requested drug only.
The unblinded subjects by the investigator will discontinue participation in the study. In addition, 
the major reasons for discontinuation (the event(s) or condition led to unblinding) will be described on 
case report form (CRF). 
The Global Clinical Safety and Pharmacovigilance (GCSP) of the sponsor may disclose the 
assigned treatment in the subject, who experienced serious adverse events. For serious adverse events 
requiring emergency report to the regulatory authority, a copy of an emergency report on the assigned 
treatment of the subject may be sent to the study involving investigator in accordance with the 
regulations, policy of the sponsor, or both.  
7.5.
Preparation/Handling/Storage/Control
1.
The investigator or designee must confirm appropriate temperature conditions have been 
maintained during transit for all study treatment received and any discrepancies are reported and 
resolved before use of the study treatment. 
2.
Only participants enrolled in the study may receive study treatment and only authorized site staff 
may supply or administer study treatment. All study treatments must be stored in a secure, 
environmentally controlled, and monitored (manual or automated) area in accordance with the 
labeled storage conditions with access limited to the investigator and authorized site staff. 
3.
The investigator, institution, or the head of the medical institution (where applicable) is

DISCONTINUATION CRITERIA
8.1.
Discontinuation of Study Treatment
The efficacy of the investigational product used in this study sustains for about 3 to 4 months 
following a single dose, and thus daily dosage is not required; accordingly, treatment discontinuation 
shall not be defined in this study, and will be considered to be identical to subject withdrawal from 
this study.
8.2.
Withdrawal from the Study

A participant may withdraw from the study at any time at his/her own request, or may be 
withdrawn at any time at the discretion of the investigator for safety, behavioral, compliance 
or administrative reasons. 

If the participant withdraws consent for disclosure of future information, the sponsor may 
retain and continue to use any data collected before such a withdrawal of consent. 

If a participant withdraws from the study, he/she may request destruction of any samples 
taken and not tested, and the investigator must document this in the site study records. 

A subject discontinuing this study must visit the study site for study termination assessment 
promptly upon decision to discontinue the study.

Refer to the schedule of assessment (SoA), completion visit (FV), for the details of data to 
be collected at the study discontinuation, and additional assessment that must be completed.
8.2.1.
Liver Chemistry Stopping Criteria
A set of criteria for study discontinuation and follow-up investigation based on hepatic function 
test (in reference to FDA premarketing clinical liver safety guidance) is specified herein to ensure the 
safety of subjects and to evaluate the causes of hepatic events. The guidelines related to this protocol

are based on the FDA premarketing clinical liver safety guidance: 
http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/UCM1
74090.pdf.
The investigator should consider discontinuing the study treatment upon discovery of liver function 
test abnormal, and if the subject is applicable to any of the symptoms presented in the algorithm, or 
such discontinuation is determined to be the best choice for the subject as judged by the investigator.

8.2.2.
QTc Stopping Criteria

For a decision on a subject's eligibility or study discontinuation, the same method for 
correction of QT interval must be used in the subject throughout the study, and must not be 
changed once the subject is enrolled. 

For instance, if a subject is enrolled based on QTcB, decisions on the subject's 
withdrawal must be made based on QTcB. 

The method used for correction of QT interval pertinent to the enrollment of a subject 
must be used for all QTc data to be collected throughout the study for the data analysis 
on the subject; provided that such rule is not applicable to ECG intended to ensure 
safety and also ECG not defined in the protocol. 

QTc should be determined based on a single measurement of ECG or the mean of ECG 
measured at 3 timepoints in a short period of time (e.g., 5 to 10 minutes). If abnormality is 
detected in a single measurement, ECG should be measured again, this time, at 3 timepoints. 

The lowest value of QTc cannot be used for a decision to withdraw a subject. 
Refer to the schedule of assessment (SoA), completion visit (FV), for the details of data to be 
collected at the discontinuation of study treatment. Discontinue this study if the mean ECG is 
applicable to any of the following conditions:

QTc >500 msec or uncorrected QT >600 msec

Change in QTc from baseline >60 msec
The following withdrawal criteria should be applied for subjects with bundle branch block: 
Baseline for subjects with bundle branch block

8.2.3.
Treatment discontinuation due to treatment-related SAE
A subject should be withdrawn from this study if treatment-related serious adverse event has 
occurred.
8.2.4.
Treatment discontinuation due to pregnancy
A female subject who become pregnant during this study must be withdrawn from the study.
8.2.5.
Withdrawal of subjects who start receiving prohibited medications or 
therapies
If a prohibited medication or therapy (See section 7.7.2.) needs to be started during the study, the 
subject must be withdrawn from this study; in which case, the subject must make the study completion 
visit (FV) before starting the prohibited medication or therapy.

8.2.6.
Prohibition of treatment resumption
Study treatment must not be resumed in subjects who are once withdrawn from this study for a 
reason associated with hepatic function test, QTc, treatment-related serious adverse event, pregnancy, 
or commencement of a prohibited medication or therapy.
8.3.
Lost to follow up
A participant will be considered lost to follow-up if he or she repeatedly fails to return for scheduled 
visits and is unable to be contacted by the study site. 
The following actions must be taken if a participant fails to return to the clinic for a required study 
visit: 

The site must attempt to contact the participant and reschedule the missed visit as soon as 
possible and counsel the participant on the importance of maintaining the assigned visit 
schedule and ascertain whether or not the participant wishes to and/or should continue in the 
study.

Before a participant is deemed lost to follow up, the investigator or designee must make 
every effort to regain contact with the participant (where possible, 3 telephone calls and, if 
necessary, a certified letter to the participant’s last known mailing address or local 
equivalent methods). These contact attempts should be documented in the participant’s 
medical record. 

Should the participant continue to be unreachable, he/she will be considered to have 
withdrawn from the study with a primary reason of lost to follow-up. 
9.
STUDY ASSESSMENTS AND PROCEDURES

Study procedures and their timing are summarized in the SoA. 

Protocol waivers or exemptions are not allowed. 

Immediate safety concerns should be discussed with the sponsor immediately upon 
occurrence or awareness to determine if the participant should continue or discontinue study 
treatment. 

Adherence to the study design requirements, including those specified in the SoA, is 
essential and required for study conduct. 

All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria. The investigator will maintain a screening log to 
record details of all participants screened and to confirm eligibility or record reasons for 
screening failure, as applicable. 

Procedures conducted as part of the participant’s routine clinical management (eg, blood 
count) and obtained before signing of ICF may be utilized for screening or baseline 
purposes provided the procedure met the protocol-specified criteria and was performed 
within the time frame defined in the SoA.

Evaluation methods
9.1.1.1.
Modified Ashworth Scale (MAS)
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator will use MAS (Table 5) to 
evaluate the level of spasticity. MAS should be measured and evaluated by the investigator, 
physiotherapist, or occupational therapist who has been given the training as an assessor. 
The test should be performed on sitting position throughout the study. The affected parts should be 
extended as fast as possible to grade the flexor muscle tones. The final assessment will be made by the 
investigator in consideration of the information from physiotherapist or occupational therapist. The 
assessor should in principle remain unchanged throughout the study period.
Table 5    Modified Ashworth Scale (MAS)
0
No increase in muscle tone
1
Slight increase in muscle tone, manifested by a catch and release or by minimal resistance at 
the end of the range of motion when the affected part(s) is moved in flexion or extension
1+
Slight increase in muscle tone, manifested by a catch, followed by minimal resistance 
throughout the reminder (less than half) of the ROM (range of movement)
2
More marked increase in muscle tone through most of the ROM, but affected part(s) easily 
moved
3
Considerable increase in muscle tone passive, movement difficult
4
Affected part(s) rigid in flexion or extension

MAS measurement as inclusion criteria (Screening and Day 1)
The subject's wrist or fingers and elbow should all be evaluated as inclusion criteria. Subjects 
meeting the eligibility and randomized should be evaluated for MAS at Visit 1 of Treatment Period 1
on the same day; provided that measurement may be performed only once if the affected part to be 
evaluated is the same. The detail of inclusion criteria are shown in 6.1.

MAS measurement during the blinded period
The subject's wrist, fingers and thumb should all be evaluated during the blinded period. Likewise, 
the subject's wrist, fingers and thumb should all be evaluated for MAS at Visit 5 and QRV of the 
blinded period. Subjects meeting the eligibility and transferred to the open-label period should be 
evaluated for MAS at Visit 1 of Treatment Period 2 on the same day; provided that measurement may 
be performed only once if the affected part to be evaluated is the same. Meanwhile, MAS needs to be 
evaluated again if the affected part to be evaluated is not the same. 

MAS measurement during the open-label period
During the open-label period, MAS should be evaluated for the flexors at which the muscle given 
the study treatment functions (fingers, thumb, wrist, elbow, fore-arm) (Table 6). If the subject is 
determined to be eligible, the V5/QRV and V1 would be on the same day, and therefore, the MAS 
measured at V5/QRV of the previous treatment period should not be measured again on V1; the 
measurement on V5/QRV should be used for the assessment (Figure 6). MAS on flexors to be newly

Numeric Rating Scale (NRS) 
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator (or subinvestigator) will 
use NRS (Figure 7) to evaluate the severity of flexors pain.
The investigator will perform the interview on NRS following the assessment of MAS. Each subject 
will be interviewed on the severity of pain on the treated part when extended based on a scale with 0 
being "no pain" and 10 being "the worst imaginable pain"; 1 response on the scale should be selected 
by the subject.

wrist, elbow, fore-arm (pronate), and shoulder] will be evaluated for the severity of pain on Visit 1. 
The part to be evaluated does not have to be the same within each treatment period, but should be the 
same part as that evaluated for MAS. 
9.1.1.3.
Disability Assessment Scale (DAS)
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator (or subinvestigator) will 
use the 4 disability assessment parameters presented in Table 7 and evaluate all of them based on the 
scale presented in Table 8. Before starting the study treatment, the investigator shall discuss with the 
subject, and select and evaluate 1 parameter agreed with the subject as the "main assessment 
parameter." The assessor should in principle remain unchanged throughout the study period. The main 
assessment parameter should also remain unchanged throughout the study period.

in spasticity from predose, and the subject will evaluate it using Table 9.
9.1.1.6.
Time to patient-reported onset of spasticity symptom relief (Visit 2):
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator (or subinvestigator) will 
record the time to alleviation of spasticity reported by subjects. The investigator shall ask the subject 
whether the product was effective on the spasticity, and if the subject's response to the question is 
positive, ask him/her "how many days did it take for the therapeutic effect to appear after the current 
dose?" and record the number of days.
9.1.1.1.
Patient-reported benefit of injection (Visits 3, 4, and 5)
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator (or subinvestigator) will 
record the efficacy of treatment reported by subjects. The investigator shall ask, "Was the product
effective?" and the subject shall respond either by "Yes" or "No."
9.2.
Adverse events
Definitions of adverse events and serious adverse events (SAE) are as specified in Appendix 4.
The investigator or a person assigned by the investigator is responsible for detecting, recording, and 
reporting events that match the definitions of adverse events and SAEs, and also, responsible for 
follow-up investigations on SAEs, as well as events related to the study drug or this study, and events 
that resulted in treatment discontinuation or subject withdrawal (See section 8).

9.2.1.
Period subject to collection of data related to adverse events and SAEs, and 
the frequency of such data collection

All SAEs will be collected from the start of treatment until Final Visit at the time points 
specified in the SoA (Section 2 ). 

All AEs will be collected from the start of treatment until Final Visit at the time points 
specified in the SoA (Section 2 ). 

Medical occurrences that begin before the start of study treatment but after obtaining 
informed consent will be recorded on the Medical History/Current Medical Conditions 
section of the case report form (CRF) not the AE section. 

All SAEs will be recorded and reported to the sponsor or designee within 24 hours, as 
indicated in Appendix 4 . The investigator will submit any updated SAE data to the sponsor 
within 24 hours of it being available. 

Investigators are not obligated to actively seek AEs or SAEs in former study participants. 
However, if the investigator learns of any SAE, including a death, at any time after a 
participant has been discharged from the study, and he/she considers the event to be 
reasonably related to the study treatment or study participation, the investigator must 
promptly notify the sponsor. 

The method of recording, evaluating, and assessing causality of AEs and SAEs and the 
procedures for completing and transmitting SAE reports are provided in Appendix 4 . 
9.2.2.
Method used to detect adverse events and SAEs
Care will be taken not to introduce bias when detecting AE and/or SAE. Open-ended and non-leading 
verbal questioning of the participant is the preferred method to inquire about AE occurrence.
9.2.3.
Follow up on adverse events and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each participant at 
subsequent visits/contacts. All SAEs will be followed until the event is resolved, stabilized, otherwise 
explained, or the participant is lost to follow-up (as defined in Section 8.3). Further information on 
follow-up procedures is given in Appendix 4.
9.2.4.
Regulatory requirements of SAE reporting

Prompt notification by the investigator to the sponsor of a SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of participants and the safety of a 
study treatment under clinical investigation are met. 

The sponsor has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study treatment under clinical investigation. The 
sponsor will comply with country-specific regulatory requirements relating to safety 
reporting to the regulatory authority, Institutional Review Boards (IRB)/Independent Ethics 
Committees (IEC), and investigators. 

Investigator safety reports must be prepared for suspected unexpected serious adverse 
reactions (SUSAR) according to local regulatory requirements and sponsor policy and 
forwarded to investigators as necessary. 


2017N315029_00
CONFIDENTIAL
207660
47

An investigator who receives an investigator safety report describing a SAE or other 
specific safety information (eg, summary or listing of SAE) from the sponsor will review 
and then file it along with the Investigator’s Brochure and will notify the IRB/IEC, if 
appropriate according to local requirements. 
9.2.5.
Cardiovascular events and death
For any cardiovascular events detailed in Appendix 4 and all deaths, whether or not they are 
considered SAEs, specific Cardiovascular (CV) and Death sections of the CRF will be required to be 
completed. These sections include questions regarding cardiovascular (including sudden cardiac 
death) and non-cardiovascular death. 
The CV CRFs are presented as queries in response to reporting of certain CV MedDRA terms. The 
CV information should be recorded in the specific cardiovascular section of the CRF within one week 
of receipt of a CV Event data query prompting its completion. 
The Death CRF is provided immediately after the occurrence or outcome of death is reported. Initial 
and follow-up reports regarding death must be completed within one week of when the death is 
reported.
9.2.6.
Pregnancy

Details of all pregnancies in female partners of male participants will be collected after the 
start of study treatment and until Final Visit. 

If a pregnancy is reported, the investigator should inform GSK within 24 hours of learning 
of the pregnancy and should follow the procedures outlined in Appendix [X]. 

Abnormal pregnancy outcomes (eg, spontaneous abortion, fetal death, stillbirth, congenital 
anomalies, ectopic pregnancy) are considered SAE. 
9.3.
Management of overdosage
A dosage of the product exceeding 400 units within 24 hours shall be considered as overdosage in 
this study. Overdosage may cause excessive pharmacodynamic responses such as hyposthenia, 
muscular paralysis, and other localized adverse reactions. Symptoms and signs may not immediately 
appear following dose. Moreover, blepharoptosis, dysarthria, dysphagia, dyspnea, myasthenia, and 
other events suspected to be an effect on other muscles distal to the treated muscle have been reported 
overseas. If such a symptom appears, the subject should be carefully monitored, and given appropriate 
interventions, if necessary with hospitalization. Also, supportive therapies such as artificial breathing 
should be considered for respiratory symptoms.
Upon confirmation of overdosage, the investigator should;
1.
Contact the Medical Monitor immediately.
Carefully monitor the adverse event/SAE, and laboratory abnormalities in the subject for at least 4 
weeks; and 
Document the quantity of the excess dose as well as the duration of the overdosing in the CRF.. 


2017N315029_00

The investigator shall discuss with the sponsor's medical monitor on the clinical assessment of the 
subject, and upon which, decide whether or not to discontinue the study treatment.
9.4.
Safety assessments
Assessment timepoints for all safety parameters are as shown in SoA.
9.4.1.
Physical examination
Physical examination (complete version): Only during screening

The head and neck, skin, lungs, cardiovascular system, abdominal region (liver and spleen), 
gastrointestinal system, lymph node, and nervous system should be examined, and the 
results thereof should be recorded; these organs should be examined for the 
presence/absence of pre-existing conditions and abnormal findings, and if there is any 
suspected abnormality, detailed examinations should be performed. 

The pulmonary function test should be conducted in details if any sign of pulmonary 
impairment is found. For the pulmonary function test, spirometry by pulmonologists is 
recommended. 
Physical examination (simplified version): To be conducted only if an eligibility criterion is not met 
during the open-label period. 

At least, the lungs, cardiovascular system, and abdominal region (liver and spleen) should 
be examined, and the results thereof should be recorded. 

The investigator should pay attention to clinical signs and symptoms related to a history of 
serious disease. 
The physical examinations should be performed by doctors in accordance with the standard clinical 
guidelines of each study site.
9.4.2.
Vital signs

For the vital signs, body temperatures (oral, intra-aural, or axillary fossa), systolic/diastolic 
blood pressures, and pulse rates should be measured in a semi-recumbent position after a 5-
minute rest. 

If a temperature is to be measured orally, the subject must refrain from eating food or 
drinking beverage within 5 minutes before the measurement. The method for the 
measurement of body temperature must remain the same throughout the study. 

The blood pressures and pulse rates should be measured with an automated device. A 
manual method may be used only if there is no automated device available for use. 
9.4.3.
Height and weight
The standard clinical guidelines of each study site should be followed.
9.4.4.
ECG

QTc should be determined based on a single measurement of ECG or the mean of ECG 
measured at 3 timepoints in a short period of time (e.g., 5 to 10 minutes). 


2017N315029_00
CONFIDENTIAL
207660
49

An automated measurement in accordance with SoA should be used to collect data on the 
heart rates, PR, QRS, QT, and QTc interval. Refer to section 8.2.2. for QTc-related 
treatment discontinuation standard, and additional QTc to be measured as required. 

Each interval between timepoints for the measurement of ECG should be minimized as 
much possible (within 2 minutes). The measurement of ECG should be performed 3 times 
consecutively and completed within 5 to 10 minutes. 
9.4.5.
Neutralizing antibody test
The investigator shall draw blood for neutralizing antibody samples in accordance with the study 
schedule. The neutralizing antibody will be measured collectively by a central laboratories designated 
by GSK (Intertek Pharmaceutical Services Co. and Pacific BioLabs Co.). The screening samples will 
be retained temporarily by the central laboratories, and then, upon retrieval of samples from all 
subjects, will be collected and tested by Intertek for screening. Samples tested positive at Intertek will 
be separately sent to Pacific BioLabs for retest to finalize the results of neutralizing antibody test. The 
above procedures shall also be taken for samples collected for Week 12 visit during the blinded period, 
and upon completion of study treatment in all subjects.
9.4.6.
Clinical Safety Laboratory Assessments

Refer to Appendix 2 for the list of clinical laboratory parameters that should be tested, and 
to SoA for the timepoints and frequency of testing. 

The investigator must review the laboratory report, document this review, and record any 
clinically relevant changes occurring during the study in the AE section of the CRF. The 
laboratory reports must be filed with the source documents. Clinically significant abnormal 
laboratory findings are those which are not associated with the underlying disease, unless 
judged by the investigator to be more severe than expected for the participant's condition.

All laboratory tests with values considered clinically significantly abnormal during 
participation in the study should be repeated until the values return to normal or baseline or 
are no longer considered significantly

If such values do not return to normal/baseline within a period of time judged reasonable by 
the investigator, the etiology should be identified and the sponsor notified.

All protocol-required laboratory assessments, as defined in Appendix 2, must be conducted 
in accordance with the laboratory manual and the SoA.

If a result of clinical laboratory test not scheduled in the protocol is obtained by a study site, 
which requires a change in the patient management, or is determined to be clinically 
important by the investigator, that is SAE, adverse event, an event requiring dose 
modification, or any other relevant event, the record thereof must be documented in the 
CRF. 

Follow-up investigation may be performed at any time during the study as determined to be 
necessary by the investigator, or required by the Japanese regulation.

10. STATISTICAL CONSIDERATIONS
10.1.
Sample Size Determination
This study is not intended to verify a statistical hypothesis, but is rather intended to verify that the 
responder rate in the 400 units group exceeds that in the 240 units group, and for which, about 120 
subjects (60 in each treatment group) are to be enrolled.
During Treatment Period 1 of this study, 160 units of the product will be administered in the muscle 
which affects the elbow; thus, the sample size was determined in reference to an overseas phase III 
study (Study 127) in which a similar dosage as this study (150 units) was administered in the muscle 
which affects the elbow. The responder rate in the elbow at Week 6 of the initial dose in Study 127 
was 72.2% and 47.1% in the product 300 units group (150 units in the muscle which affects the elbow 
flexors) and placebo group, respectively. The number of subjects in the intention-to-treat (ITT) 
population was small in both the product 300 units group and placebo group of Study 127, which was 
18 subjects each; thus, considering the uncertainty of the results of Study 127, the responder rates in 
the product 400 units and 240 units groups in this study were conservatively assumed to be 70.0% and 
50.0%, respectively. Assuming that the sample size is 60 subjects in each group, the power of test to 
detect an intergroup difference in the responder rates would be about 62% with a two- sided
significance level of 5% while the probability of the responder rate in the product 400 units group to 
exceed that in the product 240 units group as a point-estimate would be 98%.
With about 120 subjects enrolled, 100 subjects are expected to complete Week 48 of the initial dose.
10.2.
Populations for Analyses
Populations for statistical analyses  in this study are defined as follows.
Population
Description
ITT
All subjects randomized in the study andhad at least 1 post-baseline 
efficacy assessment: ITT is the primary efficacy analysis population, and 
the subjects will be analyzed in line with the randomized treatment group. 
Safety 
All subjects randomized in the study and received study treatment at least 
once: The subjects will be analyzed based on the treatment actually given. 
10.3.
Statistical Analyses
10.3.1.
Efficacy Analyses
This study is not intended to verify a statistical hypothesis; thus, there will be no statistical test.
All of the efficacy analyses will be performed on the ITT population separately for the blinded 
period and the open-label period.

Endpoints
Statistical Analysis Methods
Primary
The primary endpoint is the proportion of subjects whose MAS score on the elbow at 
Week 6 of the initial dose decreased by at least 1 level from the baseline (responder rate). 
The primary endpoint will be calculated as the proportion of subjects whose MAS score 
decreased by at least 1 level from the baseline in the ITT population. Also, a 95% 
confidence interval of the intergroup difference in the responder rate will be computed. 
Subjects with no MAS score available at Week 6 will not be counted as subjects whose 
MAS score decreased by at least 1 level from the baseline (that is, counted in as non-
responder). 
The MAS scores, 0, 1, 1+, 2, 3, and 4 will be encoded to 0, 1, 2, 3, 4, and 5, respectively, 
for the analysis purpose. 
Secondary
Unless specified otherwise, the data up to Week 12 of treatment will be summarized for 
each repeated dose during the open-label period. 
During the blinded period, a mixed model for repeated measurement (MMRM) will be 
used for the analysis on the endpoints specified below, and the least-square mean and 95% 
confidence interval will be calculated. The details of the model will be described in the 
statistical analysis plan. For the open-label period, only a summary statistics will be 
performed for each treatment group. Missing values will not be imputed. 
Change in MAS score in the fingers, thumb, wrist, and elbow from the baseline
Change in Disability Assessment Scale (primary endpoint) from the baseline 
The proportion of subjects in whom MAS score in the fingers, thumb, wrist, and elbow 
decreased by at least 1 level from the baseline (responder rate) during the blinded period 
will be analyzed with the same method as that for the primary endpoint. For the open-
label period, the denominator to be used for the calculation of responder rate shall be the 
number of subjects in each subgroup stratified by the number of injections given, not the 
ITT population. Also, a 95% confidence interval of the intergroup difference in the 
responder rate will not be calculated. 
Exploratory
Time to patient-reported onset of spasticity symptom relief will be evaluated for subjects 
who reported alleviation of spasticity at in 2 weeks postdose. The number of days from 
dose to the alleviation of spasticity will be summarized for each treatment group. 
Clinical Global Impression of Change (CGI) assessed by a investigator, CGI assessed by a 
patient, and Patient-reported benefit of injection will be summarized for each treatment 
group. Missing values will not be complemented. 
Other details will be specified in the statistical analysis plan. 
10.3.2.
Safety Analysis
Safety analyses will all be performed on the safety population separately for the blinded and open-
label periods.

Primary
Not applicable
Secondary
Adverse events that occurred in the overall study period, blinded period, and open-label 
period will be summarized for each treatment group. For the blinded period, 2 patterns of 
analyses on adverse events will be performed; one is on adverse events that occurred 
between the initial dose and the first dose in the open-label period (or at the completion 
of study if no dose is given in the open-label period or at the study withdrawal), and 
another one is on adverse events that occurred within 84 days from the initial dose. 
Adverse events will be summarized separately for SOC (system organ class) and PT 
(preferred term). Also, adverse events related to study treatment, adverse events that 
resulted indiscontinuation, adverse events by subgroups stratified by severity, and 
serious adverse events will be summarized. 
Laboratory findings and vital signs at each visit and their changes from baseline will be 
summarized for each treatment group. 
Exploratory
Will be specified in the statistical analysis plan. 
10.3.3.
Other analyses
Other analyses will be specified in the statistical analysis plan.
10.3.4.
Interim analyses
The details of the interim analysis plan will be specified in the statistical analysis plan.
When all subjects  (except for early termination) complete the visit at Week 24 of the initial dose, 
the data on all of the subjects until Week 24 of the initial dose may be locked, unblinded, and analyzed 
for reporting to authorities.

Appendix 2: Clinical Laboratory Tests

The tests detailed in Table 10 will be performed by central laboratory. 

A test needs to be performed by study sites only if the result cannot be obtained from the 
central laboratory in time for study treatment and/or assessment. Even if measurement is 
performed at a study site, another sample at the same assessment timepoint is separately 
required for measurement at central laboratory. If a result of measurement at the study site 
is to be used for a decision of study treatment and/or assessment, the result should be 
recorded in the CRF. 

Protocol-specific inclusion/exclusion criteria are as specified in section 6 of the protocol.

Caution: 
1. Details of the discontinuation criteria based on hepatic function test, and the interventions and follow up 
necessary after the occurrence of hepatic events are specified in section 8.1 and Appendix 6. SAEs must 
be reported for all events with ALT IJYO3 times the upper limit of normal range (ULN), and at the same 
time, bilirubin IJYO2 times the ULN (direct bilirubin >35%), or ALT IJYO3 times the ULN, and at the 
same time, the international normalized ratio (INR) >1.5 if measured [which suggests a possibility of 
severe liver injury (applicable to Hy's Law)]. 
2. Pregnancy tests should be performed with serum samples at screening, and with urine samples for 
routine tests after randomization.

APPENDIX 4: Adverse Events: Definitions and Procedures for Recording, 
Evaluating, Follow-up, and Reporting
Definition of AE
AE Definition

An AE is any untoward medical occurrence in a clinical study participant, temporally 
associated with the use of a study treatment, whether or not considered related to the study 
treatment.

NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of a study treatment.
Events Meeting the AE Definition

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or other
safety assessments (eg, ECG, radiological scans, vital signs measurements), including those 
that worsen from baseline, considered clinically significant in the medical and scientific 
judgment of the investigator (ie, not related to progression of underlying disease).

Exacerbation of a chronic or intermittent pre-existing condition including either an increase in 
frequency and/or intensity of the condition.

New conditions detected or diagnosed after study treatment administration even though it may 
have been present before the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction.

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study treatment or 
a concomitant medication. Overdose per se will not be reported as an AE/SAE unless it is an 
intentional overdose taken with possible suicidal/self-harming intent. Such overdoses should 
be reported regardless of sequelae.

"Lack of efficacy" or "failure of expected pharmacological action" per se will not be reported 
as an AE or SAE. Such instances will be captured in the efficacy assessments. However, the 
signs, symptoms, and/or clinical sequelae resulting from lack of efficacy will be reported as 
AE or SAE if they fulfill the definition of an AE or SAE.

The signs, symptoms, and/or clinical sequelae resulting from lack of efficacy will be reported 
as AE or SAE if they fulfill the definition of an AE or SAE. Also, "lack of efficacy" or 
"failure of expected pharmacological action" constitutes an AE or SAE.


2017N315029_00
CONFIDENTIAL
207660
62
Events NOT Meeting the AE Definition

Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the participant’s condition.

The disease/disorder being studied or expected progression, signs, or symptoms of the 
disease/disorder being studied, unless more severe than expected for the participant’s 
condition.

Medical or surgical procedure (eg, endoscopy, appendectomy): the condition that leads to 
the procedure is the AE.

Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital).

Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or 
detected at the start of the study that do not worsen.
Definition of an SAE
If an event does not correspond any of the above definitions of an AE, even if it is a serious condition, 
it will not be regarded as an SAE (e.g.; hospitalization due to the signs/symptoms of the disease being 
studied, death caused by exacerbation of the disease).
A SAE is defined as any untoward medical occurrence that, at any dose:
a.
results in death
b.
is life-threatening
The term 'life-threatening' in the definition of 'serious' 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, which hypothetically might have 
caused death, if it were more severe.
c.
requires hospitalization or prolongation of existing hospitalization
In general, hospitalization signifies that the subject has been detained (usually involving at least an 
overnight stay) at the hospital or emergency ward for observation and/or treatment that would not 
have been appropriate in the investigator’s office or out-patient setting. Complications that occur 
during hospitalization are AEs. If a complication prolongs hospitalization or fulfils any other serious 
criteria, the event is serious. When in doubt as to whether “hospitalization” occurred or was necessary, 
the AE should be considered serious. Hospitalization for elective treatment of a pre-existing condition 
that did not worsen from baseline is not considered an AE.
d.
Results in persistent disability/incapacity

The term disability means a substantial disruption of a person’s ability to conduct normal 
life functions.

This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, and 
accidental trauma (e.g. sprained ankle) which may interfere or prevent everyday life 
functions but do not constitute a substantial disruption.
e.
is congenital anomaly/birth defect


2017N315029_00
CONFIDENTIAL
207660
63
f.
other important medical situations:

Medical or scientific judgement should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize the 
subject or may require medical or surgical intervention to prevent one of the other outcomes 
listed in the above definition. These should also be considered serious.
Examples of such events are invasive or malignant cancers, intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or convulsions that 
do not result in hospitalization, or development of drug dependency or drug abuse.
Cardiovascular Events (CV) Definition:
Investigators will be required to fill out the specific CV event page of the CRF for the following AEs 
and SAEs:

Myocardial infarction/angina unstable

Cardiac failure congestive

Arrhythmia

Valvular disease

Pulmonary hypertension

Cerebrovascular event/stroke and transient ischemic attack

Peripheral arterial thromboembolism

Deep vein thrombosis/pulmonary embolism

Revascularisation
Recording of AEs and SAEs
AE and SAE Recording

When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (eg, hospital progress notes, laboratory, and diagnostics reports) related to 
the event.

The investigator will then record all relevant AE/SAE information in the CRF.

It is not acceptable for the investigator to send photocopies of the participant’s medical 
records to GSK in lieu of completion of the GSK /AE/SAE CRF page.

There may be instances when copies of medical records for certain cases are requested by 
GSK. In this case, all participant identifiers, with the exception of the participant number, 
will be redacted on the copies of the medical records before submission to GSK.

The investigator will attempt to establish a diagnosis of the event based on signs, symptoms, 
and/or other clinical information. Whenever possible, the diagnosis (not the individual 
signs/symptoms) will be documented as the AE/SAE.


2017N315029_00
CONFIDENTIAL
207660
64
Assessment of intensity
The investigator will make an assessment of intensity for each AE and SAE reported during the study 
and classify it to one of the following categories:

Mild: An event that is easily tolerated by the subject, causing minimal discomfort and not 
interfering with everyday activities.

Moderate: An event that is sufficiently discomforting to interfere with normal everyday 
activities.

Severe: An event that prevents normal everyday activities - An AE that is assessed as severe 
will not be confused with an SAE. Severity is a category utilized for rating the intensity of 
an event; and both AEs and SAEs can be assessed as severe.
An event is defined as “serious”, not when it is assessed as severe but when it meets at least one of the 
pre-defined outcomes as described in the definition of an SAE.
Assessment of causality

The investigatoris obligated to assess the relationship between investigational product and 
the occurrence of each AE/SAE.

A “reasonable possibility” is meant to convey that there are facts/evidence or arguments to 
suggest a causal relationship, rather than a relationship cannot be ruled out.

The investigator will use clinical judgement to determine the relationship.

Alternative causes, such as natural history of the underlying diseases, concomitant therapy, 
other risk factors, and the temporal relationship of the event to the investigational product 
will be considered and investigated.

The investigator will also consult the IB, for marketed products, in the determination of 
his/her assessment.

The investigator  must record that he or she reviewed AEs and SAEs and assessed the 
causality in the medical record.

There may be situations when an SAE has occurred and the investigator has minimal 
information to include in the initial report to GSK. However, it is very important that the 
investigator always make an assessment of causality for every event prior to the initial 
transmission of the SAE data to GSK.

The investigator may change his/her opinion of causality in light of follow-up information, 
prepare and send the follow-up report of SAE by amending the assessment result of the 
causality accordingly.

The causality assessment is one of the criteria used when determining regulatory reporting 
requirements.

Follow-up of AEs and SAEs

The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by GSK to 
elucidate the nature and/or causality of the AE or SAE as fully as possible. This may 
include additional laboratory tests or investigations, histopathological examinations, or 
consultation with other health care professionals.

If a subject dies during participation in the study, the investigator will provide GSK with a 
copy of any post-mortem findings, including histopathology.

New or updated information will be recorded in the originally completed CRF.

The investigator will submit all updated SAE data to GSK within 24 hours after obtaining 
the information.
Reporting of SAEs to GSK
SAE Reporting to GSK via Electronic Data Collection Tool

The primary mechanism for reporting SAE to GSK will be the electronic data collection 
tool.

If the electronic system is unavailable for more than 24 hours, then the site will use the 
paper SAE data collection tool (see next section).

The site will enter the SAE data into the electronic system as soon as it becomes available.

The investigator or medically-qualified sub-investigator must show evidence within the 
eCRF (e.g., check review box, signature, etc.) of review and verification of the relationship 
of each SAE to IP/study participation (causality) within 72 hours of SAE entry into the 
eCRF.

After the study is completed at a given site, the electronic data collection tool will be taken 
off-line to prevent the entry of new data or changes to existing data.

If a site receives a report of a new SAE from a study participant or receives updated data on 
a previously reported SAE after the electronic data collection tool has been taken off-line, 
then the site can report this information on a paper SAE form (see next section) or to the 
SAE coordinator by telephone.

Contacts for SAE reporting can be found in ATTACHMENT.
SAE Reporting to GSK via Paper CRF

Facsimile transmission of the SAE page of the CRF is the preferred method to transmit the 
information on SAEs to GSK. 

In rare circumstances and in the absence of facsimile equipment, initial notification by 
telephone is acceptable followed by a copy of the SAE page of the CRF sent by overnight 
mail or by courier. 

Initial notification via the telephone does not replace the need for the investigator (or 
subinvestigator) to complete and sign the SAE page of the CRF within the designated 
reporting time frames.

The ATTACHMENT 1 shows a contact information to which the SAEs should be reported.

APPENDIX 5: Contraceptive Guidance and Collection of Pregnancy 
Information
Definition
Woman of Childbearing Potential (WOCBP)
A woman is considered fertile following menarche and until becoming post-menopausal unless 
permanently sterile (see below)
Women in the following categories are not considered WOCBP
1.
Premenarchal
Premenopausal female with ONE of the following:

Documented hysterectomy

Documented bilateral salpingectomy

Documented bilateral oophorectomy
Note: Documentation can come from the site personnel’s: review of participant’s medical records, 
medical examination, or medical history interview.
Postmenopausal women

A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal 
range may be used to confirm a postmenopausal state in women not using hormonal 
contraception or hormonal replacement therapy (HRT). However, in the absence of 12 
months of amenorrhea, a single FSH measurement is insufficient.

Females on HRT and whose menopausal status is in doubt will be required to use one of the 
non-hormonal highly effective contraception methods if they wish to continue their HRT 
during the study. Otherwise, they must discontinue HRT to allow confirmation of 
postmenopausal status before study enrollment.
Contraception Guidance
Male study subject

A male study subject who has a female partner of childbearing potential can participate in 
this study if he agrees to any of the following conditions: 

He must agree not to have a sex (sexual intercourse) with a person of the opposite sex as a 
normal favourable lifestyle (continuously having no sex for a long period of time) and also 
agree to keep that condition. 

If he has a sex with a woman of childbearing potential, he must agree to use a male condom
and use at least one of the contraception methods with an annual failure rate below 1% 
which are shown in Table 11.

A male study subject who has a pregnant or breastfeeding female partner must agree not to 
have a sex from the time during the study or use a male condom when having a sex. 

A male study subject must agree not to provide his sperm during the study.

67
Female study subject
A female study subject of childbearing potential can participate in this study if she agrees to use any 
of the extremely effective methods of contraception shown in Table 11 continuously and accurately. 
Among the methods of contraception shown in Table 11, those deleted with strikethrough lines have 
neither been approved nor been accepted in Japan.
Table 11    Extremely effective methods of contraception
User-dependent extremely effective methods of contraception a
Their annual failure rates are below 1% if they are used continuously and accurately.
Contraception by mixed (estrogen and progestogen-containing) hormone preparation (inhibit 
ovulation)b

Oral

Intravaginal

Transdermal
Contraception by only progestogen-containing hormone preparation (inhibit ovulation)b

Injection
User-independent extremely effective methods of contraception

Contraception by only progestogen-containing implantable hormone preparation (inhibit 
ovulation)b

Intrauterine device (IUD)

Intrauterine system (IUS)

Bilateral tubal occlusion
Male partner’s vasectomy
(If her male partner has been vasectomised, it is an extremely effective method of contraception for a 
woman of childbearing potential if that partner is the only man with whom she has a sex and it has 
been confirmed that he is sterile. Otherwise, he/she must use other additional extremely effective 
method(s) of contraception.)
Having no sexual relations
(If the subjects decides to refrain himself or herself from having a sex of the opposite sex for the entire 
period when there is a risk of the investigational product, abstinence is deemed to be an extremely 
effective method of contraception. However, the credibility of abstinence needs to be evaluated during 
the study period and from the perspectives of the subject’s normal favourable lifestyle.)
Notes:
a.
The usual failure rate is different from the rate when contraception is used continuously and 
accurately. The subjects should use the methods of contraception that match with regulations 
concerning the methods of contraception for study subjects in each country.
b.
The efficacy of contraception by hormone preparations may decrease as a result of the interaction 
with the investigational product. In that case, the subject should use two extremely effective 
methods of contraception during the treatment period and at least for 3 months after the last dose 
of the investigational product.

Pregnancy test

A woman of childbearing potential can be enrolled to this study only if it is confirmed that 
she is negative in a highly sensitive serum pregnancy test along with her menstrual period. 

Pregnancy test should be performed if no menstruation occurred or she is suspected to be 
pregnant.

Analysis should be performed according to the package insert using a testing kit provided 
by GSK.
Collection of pregnancy information
If a male study subject’s partner becomes pregnant

Investigator will attempt to collect pregnancy information on any male participant’s female 
partner of a male study participant who becomes pregnant while participating in this study. 
This applies only to participants who receive study treatment.

After obtaining the necessary signed informed consent from the pregnant female partner 
directly, the investigator will record pregnancy information on the appropriate form and 
submit it to GSK within 2 weeks of learning of the partner’s pregnancy.

Partner will also be followed to determine the outcome of the pregnancy. Information on the 
status of the mother and child will be forwarded to GSK

Generally, follow-up will be no longer than 6 to 8 weeks following the estimated delivery 
date. Any termination of the pregnancy will be reported regardless of fetal status (presence 
or absence of anomalies) or indication for procedure.
Female Participants who become pregnant

Investigator will collect pregnancy information on any female participant, who becomes 
pregnant while participating in this study. 

Information will be recorded on the appropriate form and submitted to GSK within 24 hours 
of learning of a participant's pregnancy. 

Participant will be followed to determine the outcome of the pregnancy. The investigator 
will collect follow up information on participant and neonate, which will be forwarded to 
GSK Generally, follow-up will not be required for longer than 6 to 8 weeks beyond the 
estimated delivery date.

Any termination of pregnancy will be reported, regardless of fetal status (presence or 
absence of anomalies) or indication for procedure.

While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication 
or elective termination of a pregnancy will be reported as an AE or SAE.

A spontaneous abortion is always considered to be an SAE and will be reported as such.

Any SAE occurring as a result of a post-study pregnancy which is considered reasonably 
related to the study treatment by the investigator, will be reported to GSK as described in 
Appendix 4. While the investigator is not obligated to actively seek this information in 
former study participants, he or she may learn of an SAE through spontaneous reporting.

SYNOPSIS
Protocol Title: A phase III study (a placebo controlled, randomized, double-blind comparative study 
and an open-label, uncontrolled study) to evaluate the efficacy and safety of GSK1358820 in patients 
with post-stroke upper limb spasticity
Short Title: A phase III study to evaluate the efficacy and safety of GSK1358820 in patients with 
post-stroke upper limb spasticity
Rationale:
GSK1358820, botulinum toxin type A (hereafter referred as the product), is sterile, purified type A 
botulinum neurotoxin complex. Intramuscularly injected botulinum neurotoxin shows muscle relaxant 
effects by blocking the neuromuscular junction and inhibiting release of acetylcholine, a 
neurotransmitter. Since the approval of the product for strabismus and blepharospasm in US in 1989, 
the product is licensed for the treatment of various diseases, which respond to the muscle relaxant 
effects in more than 90 countries (as of Apr 2017).
In Japan, the product is licensed with 8 indications as an ethical drug so far: blepharospasm as a 
first indication in Oct 1996, followed by “hemifacial spasm” in Jan 2000, “spasmodic torticollis” in 
Jun 2001, “talipes equinus associated with lower limb spasticity in pediatric patients two years of age 
and older with cerebral palsy” in Feb 2009, “upper limb spasticity” and “lower limb spasticity” in Oct 
2010, “severe primary maschalephidrosis” in Nov 2012, and “strabismus” in Jun 2015. For “upper 
limb spasticity,” 240 units of the product is approved as a maximum dose per administration. In US, 
as a maximum dose per administration, 400 units of injection of the product have been approved for 
the treatment of upper limb spasticity in adult patients in 2015; therefore, the authorized dose of the 
product between US and Japan is different.
This study is a multicenter, double blind, placebo controlled phase III domestic study and aims to 
evaluate the efficacy and safety of 400 units of the product in patents with post-stroke upper limb 
spasticity. The study was planned to increase the maximum dose per administration in Japan to 400 
units from 240 because the treatment with 240 units of the product, a maximum dose per 
administration, is considered to be insufficient in some patients with post-stroke upper limb spasticity.

Number of Participants:
Approximately 120 subjects (approximately 60 in each group) will be randomized to obtain an 
evaluable subject sample of approximately 100 at Week 48 as subjects with completion of the study。
Treatment Groups and Duration:
Screening Phase (Day -28～Day -1)
Evaluation and screening tests will be performed 28 to 7 days (±3days) before initial injection 
(Day 1) as a starting point. The investigator will decide which arm to be injected during screening 
phase.
Blind Phase (minimum 12 Weeks): Placebo Controlled, Randomized, Double Blind 
Design
Subjects wkho meet the inclusion criteria will be randomly assigned 1:1 to either the 400 or the 240 
units group. 

In the 400 units group, a total of 240 units of the product will be injected into the muscles 
that act on the finger (including thumb flexors) and wrist flexors, and a total of 160 units 
into the muscles that act on the elbow flexors; a total of 400 units of the product will be 
injected.

In the 240 units group, a total of 240 units of the product will be injected into the muscles 
that act on the finger (including thumb flexors) and wrist flexors. Placebo will be injected 
into the muscles that act on the elbow flexors. A total of 240 units of the product will be 
injected.

If the total dose for the muscles that act on the finger and writs flexors is ensured by 240 units, and 
160 units for the muscles that act on the elbow flexors, the dose can be adjusted at a investigator’s 
discretion based on the subject’s symptoms.
Open-Label Phase (maximum 36 Weeks): Uncontrolled, Open-Label Design
The product of 400 units will be injected in both groups. The product can be injected up to 3 times 
after completion of Part 1 in the blind phase. In the open-label phase, subjects whom the investigator
considers eligible for the injections will be treated. The next injections cannot be performed until the 
eligibility of the subject has been confirmed by the investigator. 
In the open-label phase, the muscle to be injected and the dose will be decided by the investigator 
based on the patient’s symptoms, and a total dose of 400 units of the product will be injected in a 
divided dose. For the muscles that the investigator considers unnecessary to be treated, an injection 
may be skipped. The involving muscle and the dose do not have to be same each time always.
Eligibility Criteria for Injection in and after Part 2
In the open-label phase (Part 2, Part 3, and Part 4), only the subjects whom the investigator 
considers eligible for the study will be injected. The eligibility is evaluated at a study visit after Week 
12 (V5. If a subject does not meet the criteria at V5, the eligibility is evaluated at QRV (Qualification 
for Retreatment Visit). Subjects are considered to be eligible if following criteria are all satisfied:

a.
Test items for screening must be performed from 4 weeks to 1 weeks before Day 1 visit (±3 days).
b.
Eligibility evaluation (Qualification for Retreatment Visit: QRV) will be performed at V5 as a starting point if a subject does not meet the criteria only. The evaluation is performed at a 4-week interval, 
V5 as a starting point, The QRV when a subject meets the criteria will be a same day as the injection in the next treatment period (refer to Figure 1, Figure 2, Figure 3, Figure 4). 
c.
If a subject is evaluated to meet the eligibility for the injection in the blind phase at V5, the subject will move forward to Part 2 in the open-label phase (Namely, V5 in Part 1 and V1 in Part 2 is a same 
day). If the subject does not meet the eligibility, QRV will be performed 4 weeks later, at V5 as s starting point. 
d.
If a subject is evaluated to meet the eligibility at V5 in the open-label phase, the subject will move forward to the next treatment phase (V5 and V1 in the next treatment phase is a same day). If the 
subject does not meet the eligibility, QRV is performed 4 weeks later, V5 as a starting point. If V5 in each treatment phase is at Week 48 after initial injection, V5 will be considered to be completion
visit (FV). However, for the testing items, pre-scheduled tests at V5 and neutralizing antibody tests will be performed. If V5 in Parts 2 and 3 is performed at Week 36 or later, after completion of V5, 
completion visit will be performed at Week 48.
e.
QRV is allowable to perform from initial injection to Week 36. Eligibility evaluation (QRV) will not be performed after Week 36.  
f.
V5 must be performed at least 84 days after V1. 
g.
The acceptable visit windows will be -14 to +4 days if QRV is performed at Week 36.
h.
Must be performed earlier than any other procedures
i.
Must be performed before injection of the product
j.
For inclusion/exclusion criteria, the items to be observed are different between screening phase and Day 1. For details, refer to 6.1. and 6.2.
k.
For MAS evaluation, the items to be evaluated differ depending on the treatment phase. For details, refer to 9.1.1.1.
l.
MAS evaluation will be followed by NRS evaluation. For NRS evaluation, items to be evaluated differ. For details, refer to 9.1.1.2.
m.
Body temperature, heart rate, and blood pressure will be measured as vital signs. 
n.
Women of childbearing potential will be only performed. Serum hCG pregnancy test must be performed at screening, and urine hCG pregnancy test after randomization. The tests can be performed 
beyond the protocol specifications if a investigator considers to be necessary.  
o.
For laboratory test items, refer to 12.2. Attachment 2. Fasting is not required for blood collection. 
p.
Adverse events and serious adverse events collection period will be from the initial injection day (Day 1) to completion visit (FV).
q.
Neutralizing antibody testing is performed 3 times in each subject. The first test will be performed in screening phase, the second is at V5 in the blind phase, and the third is at completion visit.
r.
A subject who withdraws the study before 12 weeks after last injection will be performed. 
s.
Perform if V5 in each treatment phase is at Week 48 after initial injection
t.
Not necessary to perform doubly as V1 assessment if the same assessment is performed at V5 or QRV
u.
Evaluation of retreatment is performed only when the dosing conditions (1 to 5) of retreatment evaluation are met.

INTRODUCTION 
3.1.
Study Rationale
GSK1358820, botulinum toxin type A (hereafter referred to as the product) is sterile, purified type 
A botulinum neurotoxin complex. Intramuscularly injected botulinum neurotoxin shows muscle 
relaxant effects by blocking the neuromuscular junction and inhibiting the release of acetylcholine, a 
neurotransmitter. Since the approval of the product for strabismus and blepharospasm in US in 1989, 
the product is licensed for the treatment of various diseases, which respond to the muscle relaxant 
effects in more than 90 countries (as of Apr 2017). 
In Japan, the product is licensed with 8 indications as an ethical drug so far: blepharospasm as first 
indication in Oct 1996, followed by “hemifacial spasm” in Jan 2000, “spasmodic torticollis” in Jun 
2001, “talipes equinus associated with lower limb spasticity in paediatric patients two years of age and 
older with cerebral palsy” in Feb 2009, “upper limb spasticity” and “lower limb spasticity” in Oct 
2010, “severe primary maschalephidrosis” in Nov 2012, and “strabismus” in Jun 2015. For “upper 
limb spasticity,” 240 units of the product is approved as a maximum dose per administration. 
This study is a multicenter, double blind, placebo controlled phase III domestic study in patients 
with upper limb spasticity and aims to confirm the efficacy and safety of 240 units of the product for 
post-stroke upper limb spasticity. The information of 400 units of the product in the study is expected 
to provide beneficial information because the treatment with 240 units of the product with a maximum 
dose per administration is considered to be insufficient in some patients with post-stroke upper limb 
spasticity.
3.2.
Background
Spasticity is a movement disorder that is characterized by increased myotatic reflex and is regarded 
as one of positive signs of the upper motor neuron signs (Kagamihara, 2012; Lance, 1980). Spasticity 
is caused by central nerve system injuries such as stroke, traumatic brain injury, or spinal cord injury 
and chronic neuropathies such as cerebral palsy or multiple sclerosis, etc. Abnormal postures of the 
upper limbs due to spasticity include thumb refraction, a clenched fist deformity, flexion of the wrist 
flexors, pronation of the forearms, flexion of the elbow flexors, and adduction/inner rotation of the 
shoulder flexors (Gracies, 2003; Kinoshita, 2015). 
Spasticity hampers rehabilitation therapy. In addition, limitation of flexors range of motion and 
persistent pain hinder from caregiving and decrease activity in daily life (Grazko, 1995); therefore, 
many of patients with stroke require treatments to ameliorate their dysfunction.
For the treatments of spasticity, rehabilitation therapy, oral medications, phenol blocks, and 
baclofen injections were used until botulinum therapy has been approved as a national health 
insurance coverage. These treatments were commonly challenging because of lack of effects, difficult 
procedures, or invasive interventions. Subsequently, in Oct 2010, the product was approved as a 
botulinum treatment for upper and lower limb spasticity in Japan. Since then, botulinum toxin has 
been used for the treatment of spasticity (Ohsawa, 2013). According to the “Japanese Guidelines for 
the Management of Stroke” (initial version in 2009, revised in 2015) (Ogawa, 2015; Shinohara, 2009), 
which was issued by the Japan Stroke Society, botulinum therapy is recommended for the treatment of 
spasticity as Grade A, and is considered to be effective for relief of upper limb spasticity, increase of 
range of motions in flexors, and reduction of the amount of assistance on daily life.

In Japan, upper limb spasticity, a domestic phase II study involving the finger, wrist, and elbow 
flexors was performed from Dec 2001 through Mar 2003, and a domestic phase III study involving the 
finger and wrist flexors from May 2007 through Dec 2008. Consequently, the product was approved 
for the treatment of upper limb spasticity with a maximum dose of 240 units per administration in Oct 
2010. 
However, subsequently, the injections of the product at 240 units were found to be insufficient for 
the involving muscles because patients with extensive upper limb spasticity require dose adequate to 
inject into many of the involving muscles. Therefore, many medical institutions requested us to 
increase the maximum dose per administration of the product. Moreover, the specified drug-use 
survey from Jun 2011 through Apr 2014 identified that approximately 39% of the patients who use the 
product for upper limb spasticity were injected more than 240 units, a maximum dose per 
administration. The results suggest high patient needs for an increase of the maximum dose per 
administration of the product. 
In US, as a maximum dose per administration, 400 units of injections of the product have been 
approved for the treatment of upper limb spasticity in adult patients in 2015; therefore, the authorized 
dose between US and Japan is different. 
Based on these background, the study was planned to evaluate the efficacy and safety of 400 units 
of the product for upper limb spasticity in order to increase the maximum dose per administration to 
400 units. 
The study was planned based on the regulatory advice by the Pharmaceuticals and Medical Devices 
Agency (PMDA).

Measures for risk minimization
Investigational product :GSK1358820
Hypersensitivity
Serious and/or immediate hypersensitivity reactions
(anaphylaxis, serum sickness, urticarial, soft tissue 
edema, or dyspnea, etc.) have been rarely reported. 
Patients who previously experienced allergic reactions 
due to botulinum toxin type A, an additive agent of 
sodium chloride, or human serum albumin are 
excluded from enrolment. Upon written informed 
consent process, subjects will be explained that any 
urticarial, swelling face, throat swelling, wheezing, 
dizziness, or dyspnoea should contact their
investigator. 
Pre-existing neuromuscular disorder
Patients with neuromuscular junction diseases 
(myasthenia gravis, Lambert-Eaton myasthenic 
syndrome etc.) may increase the sensitivity to the 
product, resulting in excessive muscular weakness. 
For patients with myasthenia gravis, Eaton-Lambert 
syndrome (ELS), amyotrophic lateral sclerosis, or a 
serious disease and who use a concomitant drug (s) 
which may inhibit neuromuscular function, exclusion 
criteria will be set, and those patients will be excluded 
from enrolment in the study (refer to 6.2.1). 
distant spread of toxin
Adverse drug reactions in the remote muscles, except 
but the injected site, have been rarely reported. The 
adverse drug reactions include muscular weakness, 
constipation, dysuria, swallowing difficult, and non-
accidental entering of food or fluid in the lungs not via 
the stomach, but the trachea (pneumonia may occur). 
The patients who received the product at a higher dose 
are considered likely to have increased risks for these 
adverse drug reactions. 
In this study, a high dose of 400 units of the product 
will be injected. Therefore, the subjects will be 
followed up after 2, 4, 6, and 12 weeks of injection. 
The safety of the subjects will be observed carefully.
Use of at least one of the following guide tools 
(electromyogram, electrical stimulator, or 
ultrasonography) will be essential in the blind phase to 
ensure identification of the exact site of injection.

Important identified risks
Reports suggesting risks/ Outlines of rationale
Measures for risk minimization
Immunogenicity, drug resistance, antibody production The important cause of neutralizing antibody 
production has not been fully clarified. A few studies 
suggested that the injection of the product at short 
intervals or at a high dose may lead to increased rate 
of antibody production[Jankovic, 2006; Klein, 2002]. 
Neutralizing antibody production against botulinum 
toxin type A may lead to inactivation of the biological 
activity of the product, resulting in decreased 
therapeutic effects of the product.
In this study, patients who were considered likely to 
have neutralizing antibody production based on the 
previous treatment experience of botulinum toxin type 
A will be excluded from enrolment in the study 
(Exclusion Criteria 6.2.1).
In addition, treatment schedule in the study was set to 
ensure at least a 12-week dosing interval. 
Other (If applicable)
Medication error (preparation with lidocaine)
One fatal case due to anaphylaxis has been reported. 
In this case, the patient died after 100 units of an 
injection of the product that prepared inappropriately 
with 5 mL of 1% lidocaine. The causal relationship of 
death to the product and lidocaine, or both has been 
unknown. 
In this study, the product will be prepared
appropriately with 0.9% normal saline. The 
preparation method will be described on the study 
reference manual (SRM).

3.3.2.
Benefit Assessment
In patients with post-stroke upper limb spasticity, currently, the product is approved to inject up to 
240 units per administration in Japan. However, in patients with extensive upper limb spasticity, the 
treatment effects of the product is presumed to lack because of the dose limitation.
In US, the efficacy and safety of the product up to 400 units per dose for patients with upper limb 
spasticity is confirmed, and the clinical use of the product has been approved. The injections of 400 
units of the product in this study are expected to increase injectable sites and enhance the treatment 
effects in Japanese patients with upper limb spasticity, who did not have great benefits from 240 units 
of the product.
If a subject is assigned to the 240 units group in Part 1 and meets the eligibility criteria for injection in 
the open-label phase, 400 units of the product will be injected in and after Part 2. Therefore, all the 
subjects who participate in this study are given the opportunity to receive 400 units of the product 
(Refer to “5. STUDY DESIGN”). 
3.3.3.
Overall Benefit:Risk Conclusion
The known potential risks in the product is justified by the benefits which would provide for the 
patients with post-stroke upper limb spasticity, given the safety measures to minimize risks in subjects 
who enrol in the study.

Figure 5   Study Design
In this study, the efficacy of 400 units of the product at Week 6 is evaluated, comparing to that of 
240 units, and improvement tendencies are also evaluated in patients with post-stroke upper limb 
spasticity. The improvement will be defined as at least 1 reduction on the MAS score from baseline (a 
measurement value before injection of Day 1). The responder rate (the rate of the subjects that MAS 
score is reduced at least 1 from baseline) in the elbow flexors at Week 6 is set as an endpoint. As a 
point estimate, if the responder rate in the 400 units group outweighs that in the 240 units group, 
improvements tendencies will be considered to be positive. 
For injection, use of the following any one of the tools: EMG, electrical stimulator, or 
ultrasonography, is recommended to ensure identification of the exact injection site. In the blind phase, 
use of at least one of the following tools: EMG, electrical stimulator, or ultrasonography, will be 
essential to ensure identification of the muscle to be injected correctly. 
5.1.1.
Screening Phase (up to 4 weeks) 
Evaluation and screening tests will be performed 28 days to 7 days (+3 days) before initial injection 
(Day 1) as a starting point. The investigator will decide which arm to be injected during screening 
phase. Throughout the study period, the arm, which is decided to be injected at screening phase will 
be involved during the injections and evaluations, unless clearly specified otherwise by the sponsor.

Blind Period (minimum 12 Weeks): Placebo Controlled, Randomized, Double 
Blind Design
Subjects who meet the inclusion criteria will be randomized 1:1 to either the 400 units or the 240 
units group. 

In the 400 units group, a total of 240 units of the product will be injected into the muscles 
that act on the finger (including thumb flexors) and wrist flexors, and a total of 160 units 
into the muscles that act on the elbow flexors; a total of 400 units of the product will be 
injected.

In the 240 units group, a total of 240 units of the product will be injected into the muscles 
that act on the finger (including thumb flexors) and wrist flexors. Placebo will be injected 
into the muscles that act on the elbow flexors. A total of 240 units of the product will be 
injected.
If the total dose for the muscles that act on the finger and writs flexors is ensured by 240 units, and 
160 units for the muscles that act on the elbow flexors, the dose can be adjusted at a investigator’s 
discretion based on the subject’s symptoms. (Refer to “7.1. Treatments Administered” Table 2).
5.1.3.
Open-Label Phase (maximum 36 weeks): Uncontrolled, Open-Label Design
The product of 400 units will be injected in both groups. The product can be injected up to 3 times 
after completion of Part 1 in the blind phase. In the open-label phase, subjects whom the investigator 
considers eligible for the injection will be treated (Refer to 5.1.3.1. Eligibility Criteria for Injection in 
and after Part 2). The next injection cannot be performed until the eligibility of the subject has been 
confirmed by the investigator (Refer to 5.1.3.1. Eligibility Criteria for Injection in and after Part 2).
In the open-label phase, the muscle to be injected and the dose will be decided by the investigator
based on the patient’s symptoms, and a total dose of 400 units of the product will be injected in a 
divided dose (Refer to "7.1. Treatments Administered” on Table 3). For the muscles that the
investigator considers unnecessary to be treated, an injection may be skipped. The involving muscle 
and the dose do not have to be same each time always.
5.1.3.1.
Eligibility Criteria for Injection in and after Part 2
In the open-label phase (Part 2, Part 3, and Part 4), the subjects whom the investigator considers
eligible for the injections in the open-label phase only will be treated. The eligibility is evaluated at a 
study visit after Week 12 (V5, if a subject does not meet the eligibility criteria, the evaluation will be 
performed at QRV (Qualification for Retreatment Visit). A subject will be considered as eligible when 
he or she meets all the criteria. The eligibility evaluation will be performed after completion of Part 1 
in the blind phase, between Week 12 to Week 36. If a subject does not meet the eligibility at Week 36, 
subsequent evaluation will not be performed, and the product cannot be given (refer to Figure 1, 
Figure 2, Figure 3, and Figure 4).

5.4.
Scientific Rationale for Study
The study design was set to evaluate the efficacy and safety of 400 units of the product in patients 
with post-stroke upper limb spasticity. The primary endpoints employed the responder rate of the 
MAS score in the elbow flexors. The reasons for employing MAS score as an indicator include that 
MAS is highly reliable for evaluation of upper limb spasticity (Bohannon, 1987; Mutlu, 2008); 
especially, for evaluation of spasticity in the elbow flexors in the upper limbs (Gregson, 2000; Sloan, 
1992). 
Screening Phase
The screening phase up to 28 days before initial injection was set in order to confirm subjects meet 
the inclusion criteria and none of the exclusion criteria, and assess the condition of subjects at baseline. 
However, measurements of laboratory parameters at screening phase should be completed by 4 days 
before Day 1 (Day -28 to -4). 
Treatment Phase 
In Part 1, a double blind comparative study was set to compare the efficacy of the product of 400 
units to 240 units, the currently approved dose for upper limb spasticity. In the blind phase, 240 units 


2017N315029_01

27
of the product will be injected into the muscles that act on the finger (including the thumb)/wrist 
flexors, and 160 units (the 400 units group) or placebo (the 240 units group) for the muscles that act 
on the elbow flexors. The improvement tendencies in the efficacy between the 240 units group, the 
total dose, and the 400 units groups will be compared by evaluating the responder rate tendencies on 
the MAS score in the elbow flexors in a blinded manner. In the previous confirmatory study (108509 
study) for approval of the product for upper limb spasticity, the elbow flexors were not involved. 
Therefore, in this study, the responder rate on the MAS score in the elbow flexors was decided to 
compare as the placebo group. 
Actually, in medical institutions, the product is injected into the whole upper limb, including the 
shoulder flexors. In addition, the dose for each muscle is decided at a investigator’s discretion. 
Previous studies reported that botulinum injections into the pectoralis major and teres major muscle 
relieved pain in patients with hemiplegia (Marciniak, 2012) and injections into the sub-scapula 
improved passive range of motion (Yelnik, 2007). Therefore, in and after Part 2 in the open-label 
phase, the product will be allowed to be injected not only into the muscles that acts to the finger 
(including the thumb), wrist, and elbow flexors, but also the muscles that act on the shoulder flexors, 
where applicable, enabling a investigator to decide the dose for each muscle. In addition, the study 
design included safety evaluation of the product at Week 48 after initial injection in all subjects as far 
as possible for safety evaluation purposes of 400 units. 
5.5.
Dose Justification
The product of 400 units is a maximum dose for upper limb spasticity, which was approved by the 
U.S. Food and Drug Administration (FDA), and this suggests that the efficacy and safety profiles are 
favourable. Evaluation of the efficacy and safety of 400 units of the product provides beneficial 
information in Japanese patients with severe post-stroke upper limb spasticity, who are considered 
injections of 400 units of the product are necessary. 
The dose of 240 units of the product, the controlled group, in the blind phase (Part 1) is the current 
authorized dose (a maximum dose per administration) for upper limb spasticity in Japan. In this study, 
the 240 units group was set as the control group in order to evaluate improvement tendencies, 
comparing the efficacy of 240 units of the product, the current approved dose, to that of 400 units of 
the product.

and dropped out (However, the dropout period will be for within only 1 month from the 
dropout). 

For some reasons, a subject cannot make a study visit or undergo examination 

Sample collection or examination cannot be performed because of procedural or technical 
problems
The investigator must carefully consider the ethical aspects of subjects, and if other treatments are 
considered to give more treatment benefits for a subject, rescreening must not be conducted.

Method of Treatment Assignment
After completion of all evaluations at screening phase/initiation of the blind phase, the subjects who 
met the inclusion criteria and none of the exclusion criteria will be given their randomization number
at a case registry center and randomized to either the 240 or 400 units group. The assigned 
randomization number cannot be re-used. The table of the allocation will be prepared via a computer 
in GSK, using the RandAll systems. 
Based on the MAS score (3 or 4) in the elbow flexors, subjects will be stratified at the time of 
randomization. 
The subjects who meet the eligibility for the injections in the open-label phase can move forward to 
the open-label phase and be injected (Refer to section 5.1.3). In the open-label phase, 400 units of the 
product will be given to all subjects. Other detailed information will be described on SRM.
7.4.
Blinding
This study consists of the blind phase (Part 1), followed by the open-label phase (Part 2 and 
subsequent Parts), and in the blind phase, following processes are applied. 
A Role of the Person Responsible for Investigational Product Assignment  
The person who is responsible for investigational product assignment will prepare an operating 
procedure for the assignment. The operation will be conducted in accordance with the operating 
procedure. The person who is responsible for the investigational product assignment will display the 
drug number on a container of the investigational product (investigational product and control drug)

indistinguishability of packaging appearance. The confirmation of the investigational product 
(investigational product and control drug) and the indistinguishability of packaging appearance will be 
also performed after completion of the study. In addition, an operating procedure for occasion where 
the emergency treatment disclosure is required will be prepared. In response to the request of 
disclosure, unblinding procedures are performed for the requested drug only.
The unblinded subjects by the investigator will discontinue participation in the study. In addition, 
the major reasons for discontinuation (the event(s) or condition led to unblinding) will be described on 
case report form (CRF). 
The Global Clinical Safety and Pharmacovigilance (GCSP) of the sponsor may disclose the 
assigned treatment in the subject, who experienced serious adverse events. For serious adverse events 
requiring emergency report to the regulatory authority, a copy of an emergency report on the assigned 
treatment of the subject may be sent to the study involving investigator in accordance with the 
regulations, policy of the sponsor, or both.  
7.5.
Preparation/Handling/Storage/Control
1.
The investigator or designee must confirm appropriate temperature conditions have been 
maintained during transit for all study treatment received and any discrepancies are reported and 
resolved before use of the study treatment. 
2.
Only participants enrolled in the study may receive study treatment and only authorized site staff 
may supply or administer study treatment. All study treatments must be stored in a secure, 
environmentally controlled, and monitored (manual or automated) area in accordance with the 
labeled storage conditions with access limited to the investigator and authorized site staff. 
3.

DISCONTINUATION CRITERIA
8.1.
Discontinuation of Study Treatment
The efficacy of the investigational product used in this study sustains for about 3 to 4 months 
following a single dose, and thus daily dosage is not required; accordingly, treatment discontinuation 
shall not be defined in this study, and will be considered to be identical to subject withdrawal from 
this study.
8.2.


A participant may withdraw from the study at any time at his/her own request, or may be 
withdrawn at any time at the discretion of the investigator for safety, behavioral, compliance 
or administrative reasons. 

If the participant withdraws consent for disclosure of future information, the sponsor may 
retain and continue to use any data collected before such a withdrawal of consent. 

If a participant withdraws from the study, he/she may request destruction of any samples 
taken and not tested, and the investigator must document this in the site study records. 

A subject discontinuing this study must visit the study site for study termination assessment 
promptly upon decision to discontinue the study.


Liver Chemistry Stopping Criteria
A set of criteria for study discontinuation and follow-up investigation based on hepatic function 
test (in reference to FDA premarketing clinical liver safety guidance) is specified herein to ensure the 
safety of subjects and to evaluate the causes of hepatic events. The guidelines related to this protocol 
are based on the FDA premarketing clinical liver safety guidance: 
http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/UCM1
74090.pdf.
The investigator should consider discontinuing the study treatment upon discovery of liver function 
test abnormal, and if the subject is applicable to any of the symptoms presented in the algorithm, or 
such discontinuation is determined to be the best choice for the subject as judged by the investigator.

8.2.2.
QTc Stopping Criteria

For a decision on a subject's eligibility or study discontinuation, the same method for 
correction of QT interval must be used in the subject throughout the study, and must not be 
changed once the subject is enrolled. 

For instance, if a subject is enrolled based on QTcB, decisions on the subject's 
withdrawal must be made based on QTcB. 

The method used for correction of QT interval pertinent to the enrollment of a subject 
must be used for all QTc data to be collected throughout the study for the data analysis 
on the subject; provided that such rule is not applicable to ECG intended to ensure 
safety and also ECG not defined in the protocol. 

QTc should be determined based on a single measurement of ECG or the mean of ECG 
measured at 3 timepoints in a short period of time (e.g., 5 to 10 minutes). If abnormality is 
detected in a single measurement, ECG should be measured again, this time, at 3 timepoints. 

The lowest value of QTc cannot be used for a decision to withdraw a subject. 
Refer to the schedule of assessment (SoA), completion visit (FV), for the details of data to be 
collected at the discontinuation of study treatment. Discontinue this study if the mean ECG is 
applicable to any of the following conditions:

QTc >500 msec or uncorrected QT >600 msec

Change in QTc from baseline >60 msec
The following withdrawal criteria should be applied for subjects with bundle branch block: 
Baseline for subjects with bundle branch block
Withdrawal criteria for subjects with bundle 
branch block
<450 msec
>500 msec
450 to 480msec
IJYO530 msec
8.2.3.
Treatment discontinuation due to treatment-related SAE
A subject should be withdrawn from this study if treatment-related serious adverse event has 
occurred.
8.2.4.
Treatment discontinuation due to pregnancy
A female subject who become pregnant during this study must be withdrawn from the study.
8.2.5.
Withdrawal of subjects who start receiving prohibited medications or 
therapies
If a prohibited medication or therapy (See section 7.7.2.) needs to be started during the study, the 
subject must be withdrawn from this study; in which case, the subject must make the study completion 
visit (FV) before starting the prohibited medication or therapy.

8.2.6.
Prohibition of treatment resumption
Study treatment must not be resumed in subjects who are once withdrawn from this study for a 
reason associated with hepatic function test, QTc, treatment-related serious adverse event, pregnancy, 
or commencement of a prohibited medication or therapy.
8.3.
Lost to follow up
A participant will be considered lost to follow-up if he or she repeatedly fails to return for scheduled 
visits and is unable to be contacted by the study site. 
The following actions must be taken if a participant fails to return to the clinic for a required study 
visit: 

The site must attempt to contact the participant and reschedule the missed visit as soon as 
possible and counsel the participant on the importance of maintaining the assigned visit 
schedule and ascertain whether or not the participant wishes to and/or should continue in the 
study.

Before a participant is deemed lost to follow up, the investigator or designee must make 
every effort to regain contact with the participant (where possible, 3 telephone calls and, if 
necessary, a certified letter to the participant’s last known mailing address or local 
equivalent methods). These contact attempts should be documented in the participant’s 
medical record. 

Should the participant continue to be unreachable, he/she will be considered to have 
withdrawn from the study with a primary reason of lost to follow-up.

STUDY ASSESSMENTS AND PROCEDURES

Study procedures and their timing are summarized in the SoA. 

Protocol waivers or exemptions are not allowed. 

Immediate safety concerns should be discussed with the sponsor immediately upon 
occurrence or awareness to determine if the participant should continue or discontinue study 
treatment. 

Adherence to the study design requirements, including those specified in the SoA, is 
essential and required for study conduct. 

All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria. The investigator will maintain a screening log to 
record details of all participants screened and to confirm eligibility or record reasons for 
screening failure, as applicable. 

Procedures conducted as part of the participant’s routine clinical management (eg, blood 
count) and obtained before signing of ICF may be utilized for screening or baseline 
purposes provided the procedure met the protocol-specified criteria and was performed 
within the time frame defined in the SoA.

Evaluation methods
9.1.1.1.
Modified Ashworth Scale (MAS)
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator will use MAS (Table 5) to 
evaluate the level of spasticity. MAS should be measured and evaluated by the investigator, 
physiotherapist, or occupational therapist who has been given the training as an assessor. 
The test should be performed on sitting position throughout the study. The affected parts should be 
extended as fast as possible to grade the flexor muscle tones. The final assessment will be made by the 
investigator in consideration of the information from physiotherapist or occupational therapist. The 
assessor should in principle remain unchanged throughout the study period.
Table 5    Modified Ashworth Scale (MAS)
0
No increase in muscle tone
1
Slight increase in muscle tone, manifested by a catch and release or by minimal resistance at 
the end of the range of motion when the affected part(s) is moved in flexion or extension
1+
Slight increase in muscle tone, manifested by a catch, followed by minimal resistance 
throughout the reminder (less than half) of the ROM (range of movement)
2
More marked increase in muscle tone through most of the ROM, but affected part(s) easily 
moved
3
Considerable increase in muscle tone passive, movement difficult
4
Affected part(s) rigid in flexion or extension

MAS measurement as inclusion criteria (Screening and Day 1)
The subject's wrist or fingers and elbow should all be evaluated as inclusion criteria. Subjects 
meeting the eligibility and randomized should be evaluated for MAS at Visit 1 of Treatment Period 1
on the same day; provided that measurement may be performed only once if the affected part to be 
evaluated is the same. The detail of inclusion criteria are shown in 6.1.

MAS measurement during the blinded period
The subject's wrist, fingers and thumb should all be evaluated during the blinded period. Likewise, 
the subject's wrist, fingers and thumb should all be evaluated for MAS at Visit 5 and QRV of the 
blinded period. Subjects meeting the eligibility and transferred to the open-label period should be 
evaluated for MAS at Visit 1 of Treatment Period 2 on the same day; provided that measurement may 
be performed only once if the affected part to be evaluated is the same. Meanwhile, MAS needs to be 
evaluated again if the affected part to be evaluated is not the same. 

MAS measurement during the open-label period
During the open-label period, MAS should be evaluated for the flexors at which the muscle given 
the study treatment functions (fingers, thumb, wrist, elbow, fore-arm) (Table 6). If the subject is 
determined to be eligible, the V5/QRV and V1 would be on the same day, and therefore, the MAS 
measured at V5/QRV of the previous treatment period should not be measured again on V1; the 
measurement on V5/QRV should be used for the assessment (Figure 6). MAS on flexors to be newly

Numeric Rating Scale (NRS) 
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator (or subinvestigator) will 
use NRS (Figure 7) to evaluate the severity of flexors pain.
The investigator will perform the interview on NRS following the assessment of MAS. Each subject 
will be interviewed on the severity of pain on the treated part when extended based on a scale with 0 
being "no pain" and 10 being "the worst imaginable pain"; 1 response on the scale should be selected 
by the subject.

Clinical Global Impression of Change (CGI) assessed by a investigator
The investigator (or subinvestigator) will evaluate CGI according to "2. SCHEDULE OF 
ACTIVITIES (SoA)”; Changes in spasticity (Clinical Global Impression) from baseline (V1 in each 
treatment phase) will be evaluated by 9 grades as shown in Table 9.
The investigator shall also consider the subject's clinical symptoms and adverse events pertinent to 
the assessment of CGI. Also, the therapeutic effect of the product injected in the subject's fingers, 
wrist, and elbow should be taken into an account. The assessor should in principle remain unchanged 
throughout the study period.

According to "2. SCHEDULE OF ACTIVITIES (SoA))" the investigator (or subinvestigator) will 
use Table 9 to record subject-reported CGI. The investigator shall interview each subject on changes 
in spasticity from predose, and the subject will evaluate it using Table 9.
9.1.1.6.
Time to patient-reported onset of spasticity symptom relief (Visit 2):
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator (or subinvestigator) will 
record the time to alleviation of spasticity reported by subjects. The investigator shall ask the subject 
whether the product was effective on the spasticity, and if the subject's response to the question is 
positive, ask him/her "how many days did it take for the therapeutic effect to appear after the current 
dose?" and record the number of days.
9.1.1.1.
Patient-reported benefit of injection (Visits 3, 4, and 5)
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator (or subinvestigator) will 
record the efficacy of treatment reported by subjects. The investigator shall ask, "Was the product
effective?" and the subject shall respond either by "Yes" or "No."
9.2.
Adverse events
Definitions of adverse events and serious adverse events (SAE) are as specified in Appendix 4.
The investigator or a person assigned by the investigator is responsible for detecting, recording, and 
reporting events that match the definitions of adverse events and SAEs, and also, responsible for 
follow-up investigations on SAEs, as well as events related to the study drug or this study, and events 
that resulted in treatment discontinuation or subject withdrawal (See section 8).

9.2.1.
Period subject to collection of data related to adverse events and SAEs, and 
the frequency of such data collection

All SAEs will be collected from the start of treatment until Final Visit at the time points 
specified in the SoA (Section 2 ). 

All AEs will be collected from the start of treatment until Final Visit at the time points 
specified in the SoA (Section 2 ). 

Medical occurrences that begin before the start of study treatment but after obtaining 
informed consent will be recorded on the Medical History/Current Medical Conditions 
section of the case report form (CRF) not the AE section. 

All SAEs will be recorded and reported to the sponsor or designee within 24 hours, as 
indicated in Appendix 4 . The investigator will submit any updated SAE data to the sponsor 
within 24 hours of it being available. 

Investigators are not obligated to actively seek AEs or SAEs in former study participants. 
However, if the investigator learns of any SAE, including a death, at any time after a 
participant has been discharged from the study, and he/she considers the event to be 
reasonably related to the study treatment or study participation, the investigator must 
promptly notify the sponsor. 

The method of recording, evaluating, and assessing causality of AEs and SAEs and the 
procedures for completing and transmitting SAE reports are provided in Appendix 4 . 
9.2.2.
Method used to detect adverse events and SAEs
Care will be taken not to introduce bias when detecting AE and/or SAE. Open-ended and non-leading 
verbal questioning of the participant is the preferred method to inquire about AE occurrence.
9.2.3.
Follow up on adverse events and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each participant at 
subsequent visits/contacts. All SAEs will be followed until the event is resolved, stabilized, otherwise 
explained, or the participant is lost to follow-up (as defined in Section 8.3). Further information on 
follow-up procedures is given in Appendix 4.
9.2.4.
Regulatory requirements of SAE reporting

Prompt notification by the investigator to the sponsor of a SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of participants and the safety of a 
study treatment under clinical investigation are met. 

The sponsor has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study treatment under clinical investigation. The 
sponsor will comply with country-specific regulatory requirements relating to safety 
reporting to the regulatory authority, Institutional Review Boards (IRB)/Independent Ethics 
Committees (IEC), and investigators. 

Investigator safety reports must be prepared for suspected unexpected serious adverse 
reactions (SUSAR) according to local regulatory requirements and sponsor policy and 
forwarded to investigators as necessary. 


2017N315029_01
CONFIDENTIAL
207660


An investigator who receives an investigator safety report describing a SAE or other 
specific safety information (eg, summary or listing of SAE) from the sponsor will review 
and then file it along with the Investigator’s Brochure and will notify the IRB/IEC, if 
appropriate according to local requirements. 
9.2.5.
Cardiovascular events and death
For any cardiovascular events detailed in Appendix 4 and all deaths, whether or not they are 
considered SAEs, specific Cardiovascular (CV) and Death sections of the CRF will be required to be 
completed. These sections include questions regarding cardiovascular (including sudden cardiac 
death) and non-cardiovascular death. 
The CV CRFs are presented as queries in response to reporting of certain CV MedDRA terms. The 
CV information should be recorded in the specific cardiovascular section of the CRF within one week 
of receipt of a CV Event data query prompting its completion. 
The Death CRF is provided immediately after the occurrence or outcome of death is reported. Initial 
and follow-up reports regarding death must be completed within one week of when the death is 
reported.
9.2.6.
Pregnancy

Details of all pregnancies in female partners of male participants will be collected after the 
start of study treatment and until Final Visit. 

If a pregnancy is reported, the investigator should inform GSK within 24 hours of learning 
of the pregnancy and should follow the procedures outlined in Appendix [X]. 

Abnormal pregnancy outcomes (eg, spontaneous abortion, fetal death, stillbirth, congenital 
anomalies, ectopic pregnancy) are considered SAE. 
9.3.
Management of overdosage
A dosage of the product exceeding 400 units within 24 hours shall be considered as overdosage in 
this study. Overdosage may cause excessive pharmacodynamic responses such as hyposthenia, 
muscular paralysis, and other localized adverse reactions. Symptoms and signs may not immediately 
appear following dose. Moreover, blepharoptosis, dysarthria, dysphagia, dyspnea, myasthenia, and 
other events suspected to be an effect on other muscles distal to the treated muscle have been reported 
overseas. If such a symptom appears, the subject should be carefully monitored, and given appropriate 
interventions, if necessary with hospitalization. Also, supportive therapies such as artificial breathing 
should be considered for respiratory symptoms.
Upon confirmation of overdosage, the investigator should;
1.
Contact the Medical Monitor immediately.
Carefully monitor the adverse event/SAE, and laboratory abnormalities in the subject for at least 4 
weeks; and 
Document the quantity of the excess dose as well as the duration of the overdosing in the CRF.. 


2017N315029_01

The investigator shall discuss with the sponsor's medical monitor on the clinical assessment of the 
subject, and upon which, decide whether or not to discontinue the study treatment.
9.4.
Safety assessments
Assessment timepoints for all safety parameters are as shown in SoA.
9.4.1.
Physical examination
Physical examination (complete version): Only during screening

The head and neck, skin, lungs, cardiovascular system, abdominal region (liver and spleen), 
gastrointestinal system, lymph node, and nervous system should be examined, and the 
results thereof should be recorded; these organs should be examined for the 
presence/absence of pre-existing conditions and abnormal findings, and if there is any 
suspected abnormality, detailed examinations should be performed. 

The pulmonary function test should be conducted in details if any sign of pulmonary 
impairment is found. For the pulmonary function test, spirometry by pulmonologists is 
recommended. 
Physical examination (simplified version): To be conducted only if an eligibility criterion is not met 
during the open-label period. 

At least, the lungs, cardiovascular system, and abdominal region (liver and spleen) should 
be examined, and the results thereof should be recorded. 

The investigator should pay attention to clinical signs and symptoms related to a history of 
serious disease. 
The physical examinations should be performed by doctors in accordance with the standard clinical 
guidelines of each study site.
9.4.2.
Vital signs

For the vital signs, body temperatures (oral, intra-aural, or axillary fossa), systolic/diastolic 
blood pressures, and pulse rates should be measured in a semi-recumbent position after a 5-
minute rest. 

If a temperature is to be measured orally, the subject must refrain from eating food or 
drinking beverage within 5 minutes before the measurement. The method for the 
measurement of body temperature must remain the same throughout the study. 

The blood pressures and pulse rates should be measured with an automated device. A 
manual method may be used only if there is no automated device available for use. 
9.4.3.
Height and weight
The standard clinical guidelines of each study site should be followed.


If post-injection SpO2 is decreased by 3% or more from the baseline, medical examination 
by pulmonologist is recommended.

If a medical institution has no pulmonologist, visit other hospitals for medical examination 
by specialists. For the pulmonary function test, spirometry by pulmonologists is 
recommended.
9.4.5.
ECG

QTc should be determined based on a single measurement of ECG or the mean of ECG 
measured at 3 timepoints in a short period of time (e.g., 5 to 10 minutes). 

An automated measurement and manual re-interpretation in accordance with SoA should be 
used to collect data on the heart rates, PR, QRS, QT, and QTc interval. Refer to section 
8.2.2. for QTc-related treatment discontinuation standard, and additional QTc to be 
measured as required. 

Each interval between timepoints for the measurement of ECG should be minimized as 
much possible (within 2 minutes). The measurement of ECG should be performed 3 times 
consecutively and completed within 5 to 10 minutes. 
9.4.6.
Neutralizing antibody test
The investigator shall draw blood for neutralizing antibody samples in accordance with the study 
schedule. The neutralizing antibody will be measured collectively by a central laboratories designated 
by GSK (Intertek Pharmaceutical Services Co. and Pacific BioLabs Co.). The screening samples will 
be retained temporarily by the central laboratories, and then, upon retrieval of samples from all 
subjects, will be collected and tested by Intertek for screening. Samples tested positive at Intertek will 
be separately sent to Pacific BioLabs for retest to finalize the results of neutralizing antibody test. The 
above procedures shall also be taken for samples collected for Week 12 visit during the blinded period, 
and upon completion of study treatment in all subjects.
9.4.7.
Clinical Safety Laboratory Assessments

Refer to Appendix 2 for the list of clinical laboratory parameters that should be tested, and 
to SoA for the timepoints and frequency of testing. 

The investigator must review the laboratory report, document this review, and record any 
clinically relevant changes occurring during the study in the AE section of the CRF. The 
laboratory reports must be filed with the source documents. Clinically significant abnormal 
laboratory findings are those which are not associated with the underlying disease, unless 
judged by the investigator to be more severe than expected for the participant's condition.

All laboratory tests with values considered clinically significantly abnormal during 
participation in the study should be repeated until the values return to normal or baseline or 
are no longer considered significantly

If such values do not return to normal/baseline within a period of time judged reasonable by 
the investigator, the etiology should be identified and the sponsor notified.

All protocol-required laboratory assessments, as defined in Appendix 2, must be conducted 
in accordance with the laboratory manual and the SoA.

10. STATISTICAL CONSIDERATIONS
10.1.
Sample Size Determination
This study is not intended to verify a statistical hypothesis, but is rather intended to verify that the 
responder rate in the 400 units group exceeds that in the 240 units group, and for which, about 120 
subjects (60 in each treatment group) are to be enrolled.
During Treatment Period 1 of this study, 160 units of the product will be administered in the muscle 
which affects the elbow; thus, the sample size was determined in reference to an overseas phase III 
study (Study 127) in which a similar dosage as this study (150 units) was administered in the muscle 
which affects the elbow. The responder rate in the elbow at Week 6 of the initial dose in Study 127 
was 72.2% and 47.1% in the product 300 units group (150 units in the muscle which affects the elbow 
flexors) and placebo group, respectively. The number of subjects in the intention-to-treat (ITT) 
population was small in both the product 300 units group and placebo group of Study 127, which was 
18 subjects each; thus, considering the uncertainty of the results of Study 127, the responder rates in 
the product 400 units and 240 units groups in this study were conservatively assumed to be 70.0% and 
50.0%, respectively. Assuming that the sample size is 60 subjects in each group, the power of test to 
detect an intergroup difference in the responder rates would be about 62% with a two- sided
significance level of 5% while the probability of the responder rate in the product 400 units group to 
exceed that in the product 240 units group as a point-estimate would be 98%.
With about 120 subjects enrolled, 100 subjects are expected to complete Week 48 of the initial dose.
10.2.
Populations for Analyses
Populations for statistical analyses in this study are defined as follows.
Population
Description
ITT
All subjects randomized in the study andhad at least 1 post-baseline 
efficacy assessment: ITT is the primary efficacy analysis population, and 
the subjects will be analyzed in line with the randomized treatment group. 
Safety 
All subjects randomized in the study and received study treatment at least 
once: The subjects will be analyzed based on the treatment actually given. 
10.3.
Statistical Analyses
10.3.1.
Efficacy Analyses
This study is not intended to verify a statistical hypothesis; thus, there will be no statistical test.
All of the efficacy analyses will be performed on the ITT population separately for the blinded 
period and the open-label period.

Endpoints
Statistical Analysis Methods
Primary
The primary endpoint is the proportion of subjects whose MAS score on the elbow at 
Week 6 of the initial dose decreased by at least 1 level from the baseline (responder rate). 
The primary endpoint will be calculated as the proportion of subjects whose MAS score 
decreased by at least 1 level from the baseline in the ITT population. Also, a 95% 
confidence interval of the intergroup difference in the responder rate will be computed. 
Subjects with no MAS score available at Week 6 will not be counted as subjects whose 
MAS score decreased by at least 1 level from the baseline (that is, counted in as non-
responder). 
The MAS scores, 0, 1, 1+, 2, 3, and 4 will be encoded to 0, 1, 2, 3, 4, and 5, respectively, 
for the analysis purpose. 
Secondary
Unless specified otherwise, the data up to Week 12 of treatment will be summarized for 
each repeated dose during the open-label period. 
During the blinded period, a mixed model for repeated measurement (MMRM) will be 
used for the analysis on the endpoints specified below, and the least-square mean and 95% 
confidence interval will be calculated. The details of the model will be described in the 
statistical analysis plan. For the open-label period, only a summary statistics will be 
performed for each treatment group. Missing values will not be imputed. 
Change in MAS score in the fingers, thumb, wrist, and elbow from the baseline
Change in Disability Assessment Scale (primary endpoint) from the baseline 
The proportion of subjects in whom MAS score in the fingers, thumb, wrist, and elbow 
decreased by at least 1 level from the baseline (responder rate) during the blinded period 
will be analyzed with the same method as that for the primary endpoint. For the open-
label period, the denominator to be used for the calculation of responder rate shall be the 
number of subjects in each subgroup stratified by the number of injections given, not the 
ITT population. Also, a 95% confidence interval of the intergroup difference in the 
responder rate will not be calculated. 
Exploratory
Time to patient-reported onset of spasticity symptom relief will be evaluated for subjects 
who reported alleviation of spasticity at in 2 weeks postdose. The number of days from 
dose to the alleviation of spasticity will be summarized for each treatment group. 
Clinical Global Impression of Change (CGI) assessed by a investigator, CGI assessed by a 
patient, and Patient-reported benefit of injection will be summarized for each treatment 
group. Missing values will not be complemented. 
Other details will be specified in the statistical analysis plan. 
10.3.2.
Safety Analysis
Safety analyses will all be performed on the safety population separately for the blinded and open-
label periods.

Adverse events that occurred in the overall study period, blinded period, and open-label 
period will be summarized for each treatment group. For the blinded period, 2 patterns of 
analyses on adverse events will be performed; one is on adverse events that occurred 
between the initial dose and the first dose in the open-label period (or at the completion 
of study if no dose is given in the open-label period or at the study withdrawal), and 
another one is on adverse events that occurred within 84 days from the initial dose. 
Adverse events will be summarized separately for SOC (system organ class) and PT 
(preferred term). Also, adverse events related to study treatment, adverse events that

Appendix 2: Clinical Laboratory Tests

The tests detailed in Table 10 will be performed by central laboratory. 

A test needs to be performed by study sites only if the result cannot be obtained from the 
central laboratory in time for study treatment and/or assessment. Even if measurement is 
performed at a study site, another sample at the same assessment timepoint is separately 
required for measurement at central laboratory. If a result of measurement at the study site 
is to be used for a decision of study treatment and/or assessment, the result should be 
recorded in the CRF. 

Protocol-specific inclusion/exclusion criteria are as specified in section 6 of the protocol.

Caution: 
1. Details of the discontinuation criteria based on hepatic function test, and the interventions and follow up 
necessary after the occurrence of hepatic events are specified in section 8.1 and Appendix 6. SAEs must 
be reported for all events with ALT IJYO3 times the upper limit of normal range (ULN), and at the same 
time, bilirubin IJYO2 times the ULN (direct bilirubin >35%), or ALT IJYO3 times the ULN, and at the 
same time, the international normalized ratio (INR) >1.5 if measured [which suggests a possibility of 
severe liver injury (applicable to Hy's Law)]. 
2. Pregnancy tests should be performed with serum samples at screening, and with urine samples for 
routine tests after randomization.

APPENDIX 4: Adverse Events: Definitions and Procedures for Recording, 
Evaluating, Follow-up, and Reporting
Definition of AE
AE Definition

An AE is any untoward medical occurrence in a clinical study participant, temporally 
associated with the use of a study treatment, whether or not considered related to the study 
treatment.

NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of a study treatment.
Events Meeting the AE Definition

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or other
safety assessments (eg, ECG, radiological scans, vital signs measurements), including those 
that worsen from baseline, considered clinically significant in the medical and scientific 
judgment of the investigator (ie, not related to progression of underlying disease).

Exacerbation of a chronic or intermittent pre-existing condition including either an increase in 
frequency and/or intensity of the condition.

New conditions detected or diagnosed after study treatment administration even though it may 
have been present before the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction.

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study treatment or 
a concomitant medication. Overdose per se will not be reported as an AE/SAE unless it is an 
intentional overdose taken with possible suicidal/self-harming intent. Such overdoses should 
be reported regardless of sequelae.

"Lack of efficacy" or "failure of expected pharmacological action" per se will not be reported 
as an AE or SAE. Such instances will be captured in the efficacy assessments. However, the 
signs, symptoms, and/or clinical sequelae resulting from lack of efficacy will be reported as 
AE or SAE if they fulfill the definition of an AE or SAE.

The signs, symptoms, and/or clinical sequelae resulting from lack of efficacy will be reported 
as AE or SAE if they fulfill the definition of an AE or SAE. Also, "lack of efficacy" or 
"failure of expected pharmacological action" constitutes an AE or SAE.


2017N315029_01
CONFIDENTIAL
207660
64
Events NOT Meeting the AE Definition

Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the participant’s condition.

The disease/disorder being studied or expected progression, signs, or symptoms of the 
disease/disorder being studied, unless more severe than expected for the participant’s 
condition.

Medical or surgical procedure (eg, endoscopy, appendectomy): the condition that leads to 
the procedure is the AE.

Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital).

Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or 
detected at the start of the study that do not worsen.
Definition of an SAE
If an event does not correspond any of the above definitions of an AE, even if it is a serious condition, 
it will not be regarded as an SAE (e.g.; hospitalization due to the signs/symptoms of the disease being 
studied, death caused by exacerbation of the disease).
A SAE is defined as any untoward medical occurrence that, at any dose:
a.
results in death
b.
is life-threatening
The term 'life-threatening' in the definition of 'serious' 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, which hypothetically might have 
caused death, if it were more severe.
c.
requires hospitalization or prolongation of existing hospitalization
In general, hospitalization signifies that the subject has been detained (usually involving at least an 
overnight stay) at the hospital or emergency ward for observation and/or treatment that would not 
have been appropriate in the investigator’s office or out-patient setting. Complications that occur 
during hospitalization are AEs. If a complication prolongs hospitalization or fulfils any other serious 
criteria, the event is serious. When in doubt as to whether “hospitalization” occurred or was necessary, 
the AE should be considered serious. Hospitalization for elective treatment of a pre-existing condition 
that did not worsen from baseline is not considered an AE.
d.
Results in persistent disability/incapacity

The term disability means a substantial disruption of a person’s ability to conduct normal 
life functions.

This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, and 
accidental trauma (e.g. sprained ankle) which may interfere or prevent everyday life 
functions but do not constitute a substantial disruption.
e.
is congenital anomaly/birth defect


2017N315029_01
CONFIDENTIAL
207660
65
f.
other important medical situations:

Medical or scientific judgement should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize the 
subject or may require medical or surgical intervention to prevent one of the other outcomes 
listed in the above definition. These should also be considered serious.
Examples of such events are invasive or malignant cancers, intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or convulsions that 
do not result in hospitalization, or development of drug dependency or drug abuse.
Cardiovascular Events (CV) Definition:
Investigators will be required to fill out the specific CV event page of the CRF for the following AEs 
and SAEs:

Myocardial infarction/angina unstable

Cardiac failure congestive

Arrhythmia

Valvular disease

Pulmonary hypertension

Cerebrovascular event/stroke and transient ischemic attack

Peripheral arterial thromboembolism

Deep vein thrombosis/pulmonary embolism

Revascularisation
Recording of AEs and SAEs
AE and SAE Recording

When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (eg, hospital progress notes, laboratory, and diagnostics reports) related to 
the event.

The investigator will then record all relevant AE/SAE information in the CRF.

It is not acceptable for the investigator to send photocopies of the participant’s medical 
records to GSK in lieu of completion of the GSK /AE/SAE CRF page.

There may be instances when copies of medical records for certain cases are requested by 
GSK. In this case, all participant identifiers, with the exception of the participant number, 
will be redacted on the copies of the medical records before submission to GSK.

The investigator will attempt to establish a diagnosis of the event based on signs, symptoms, 
and/or other clinical information. Whenever possible, the diagnosis (not the individual 
signs/symptoms) will be documented as the AE/SAE.


2017N315029_01
CONFIDENTIAL
207660
66
Assessment of intensity
The investigator will make an assessment of intensity for each AE and SAE reported during the study 
and classify it to one of the following categories:

Mild: An event that is easily tolerated by the subject, causing minimal discomfort and not 
interfering with everyday activities.

Moderate: An event that is sufficiently discomforting to interfere with normal everyday 
activities.

Severe: An event that prevents normal everyday activities - An AE that is assessed as severe 
will not be confused with an SAE. Severity is a category utilized for rating the intensity of 
an event; and both AEs and SAEs can be assessed as severe.
An event is defined as “serious”, not when it is assessed as severe but when it meets at least one of the 
pre-defined outcomes as described in the definition of an SAE.
Assessment of causality

The investigatoris obligated to assess the relationship between investigational product and 
the occurrence of each AE/SAE.

A “reasonable possibility” is meant to convey that there are facts/evidence or arguments to 
suggest a causal relationship, rather than a relationship cannot be ruled out.

The investigator will use clinical judgement to determine the relationship.

Alternative causes, such as natural history of the underlying diseases, concomitant therapy, 
other risk factors, and the temporal relationship of the event to the investigational product 
will be considered and investigated.

The investigator will also consult the IB, for marketed products, in the determination of 
his/her assessment.

The investigator  must record that he or she reviewed AEs and SAEs and assessed the 
causality in the medical record.

There may be situations when an SAE has occurred and the investigator has minimal 
information to include in the initial report to GSK. However, it is very important that the 
investigator always make an assessment of causality for every event prior to the initial 
transmission of the SAE data to GSK.

The investigator may change his/her opinion of causality in light of follow-up information, 
prepare and send the follow-up report of SAE by amending the assessment result of the 
causality accordingly.

The causality assessment is one of the criteria used when determining regulatory reporting 
requirements.


2017N315029_01
CONFIDENTIAL
207660
67
Follow-up of AEs and SAEs

The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by GSK to 
elucidate the nature and/or causality of the AE or SAE as fully as possible. This may 
include additional laboratory tests or investigations, histopathological examinations, or 
consultation with other health care professionals.

If a subject dies during participation in the study, the investigator will provide GSK with a 
copy of any post-mortem findings, including histopathology.

New or updated information will be recorded in the originally completed CRF.

The investigator will submit all updated SAE data to GSK within 24 hours after obtaining 
the information.
Reporting of SAEs to GSK
SAE Reporting to GSK via Electronic Data Collection Tool

The primary mechanism for reporting SAE to GSK will be the electronic data collection 
tool.

If the electronic system is unavailable for more than 24 hours, then the site will use the 
paper SAE data collection tool (see next section).

The site will enter the SAE data into the electronic system as soon as it becomes available.

The investigator or medically-qualified sub-investigator must show evidence within the 
eCRF (e.g., check review box, signature, etc.) of review and verification of the relationship 
of each SAE to IP/study participation (causality) within 72 hours of SAE entry into the 
eCRF.

After the study is completed at a given site, the electronic data collection tool will be taken 
off-line to prevent the entry of new data or changes to existing data.

If a site receives a report of a new SAE from a study participant or receives updated data on 
a previously reported SAE after the electronic data collection tool has been taken off-line, 
then the site can report this information on a paper SAE form (see next section) or to the 
SAE coordinator by telephone.

Contacts for SAE reporting can be found in ATTACHMENT.
SAE Reporting to GSK via Paper CRF

Facsimile transmission of the SAE page of the CRF is the preferred method to transmit the 
information on SAEs to GSK. 

In rare circumstances and in the absence of facsimile equipment, initial notification by 
telephone is acceptable followed by a copy of the SAE page of the CRF sent by overnight 
mail or by courier. 

Initial notification via the telephone does not replace the need for the investigator (or 
subinvestigator) to complete and sign the SAE page of the CRF within the designated 
reporting time frames.

The ATTACHMENT 1 shows a contact information to which the SAEs should be reported.

APPENDIX 5: Contraceptive Guidance and Collection of Pregnancy 
Information
Definition
Woman of Childbearing Potential (WOCBP)
A woman is considered fertile following menarche and until becoming post-menopausal unless 
permanently sterile (see below)
Women in the following categories are not considered WOCBP
1.
Premenarchal
Premenopausal female with ONE of the following:

Documented hysterectomy

Documented bilateral salpingectomy

Documented bilateral oophorectomy
Note: Documentation can come from the site personnel’s: review of participant’s medical records, 
medical examination, or medical history interview.
Postmenopausal women

A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal 
range may be used to confirm a postmenopausal state in women not using hormonal 
contraception or hormonal replacement therapy (HRT). However, in the absence of 12 
months of amenorrhea, a single FSH measurement is insufficient.

Females on HRT and whose menopausal status is in doubt will be required to use one of the 
non-hormonal highly effective contraception methods if they wish to continue their HRT 
during the study. Otherwise, they must discontinue HRT to allow confirmation of 
postmenopausal status before study enrollment.
Contraception Guidance
Male study subject

A male study subject who has a female partner of childbearing potential can participate in 
this study if he agrees to any of the following conditions: 

He must agree not to have a sex (sexual intercourse) with a person of the opposite sex as a 
normal favourable lifestyle (continuously having no sex for a long period of time) and also 
agree to keep that condition. 

If he has a sex with a woman of childbearing potential, he must agree to use a male condom
and use at least one of the contraception methods with an annual failure rate below 1% 
which are shown in Table 11.

A male study subject who has a pregnant or breastfeeding female partner must agree not to 
have a sex from the time during the study or use a male condom when having a sex. 

A male study subject must agree not to provide his sperm during the study.

Male partner’s vasectomy
(If her male partner has been vasectomised, it is an extremely effective method of contraception for a 
woman of childbearing potential if that partner is the only man with whom she has a sex and it has 
been confirmed that he is sterile. Otherwise, he/she must use other additional extremely effective 
method(s) of contraception.)
Having no sexual relations
(If the subjects decides to refrain himself or herself from having a sex of the opposite sex for the entire 
period when there is a risk of the investigational product, abstinence is deemed to be an extremely 
effective method of contraception. However, the credibility of abstinence needs to be evaluated during 
the study period and from the perspectives of the subject’s normal favourable lifestyle.)
Notes:
a.
The usual failure rate is different from the rate when contraception is used continuously and 
accurately. The subjects should use the methods of contraception that match with regulations 
concerning the methods of contraception for study subjects in each country.
b.
The efficacy of contraception by hormone preparations may decrease as a result of the interaction 
with the investigational product. In that case, the subject should use two extremely effective 
methods of contraception during the treatment period and at least for 3 months after the last dose 
of the investigational product.

Pregnancy test

A woman of childbearing potential can be enrolled to this study only if it is confirmed that 
she is negative in a highly sensitive serum pregnancy test along with her menstrual period. 

Pregnancy test should be performed if no menstruation occurred or she is suspected to be 
pregnant.

Analysis should be performed according to the package insert using a testing kit provided 
by GSK.
Collection of pregnancy information
If a male study subject’s partner becomes pregnant

Investigator will attempt to collect pregnancy information on any male participant’s female 
partner of a male study participant who becomes pregnant while participating in this study. 
This applies only to participants who receive study treatment.

After obtaining the necessary signed informed consent from the pregnant female partner 
directly, the investigator will record pregnancy information on the appropriate form and 
submit it to GSK within 2 weeks of learning of the partner’s pregnancy.

Partner will also be followed to determine the outcome of the pregnancy. Information on the 
status of the mother and child will be forwarded to GSK

Generally, follow-up will be no longer than 6 to 8 weeks following the estimated delivery 
date. Any termination of the pregnancy will be reported regardless of fetal status (presence 
or absence of anomalies) or indication for procedure.
Female Participants who become pregnant

Investigator will collect pregnancy information on any female participant, who becomes 
pregnant while participating in this study. 

Information will be recorded on the appropriate form and submitted to GSK within 24 hours 
of learning of a participant's pregnancy. 

Participant will be followed to determine the outcome of the pregnancy. The investigator 
will collect follow up information on participant and neonate, which will be forwarded to 
GSK Generally, follow-up will not be required for longer than 6 to 8 weeks beyond the 
estimated delivery date.

Any termination of pregnancy will be reported, regardless of fetal status (presence or 
absence of anomalies) or indication for procedure.

While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication 
or elective termination of a pregnancy will be reported as an AE or SAE.

A spontaneous abortion is always considered to be an SAE and will be reported as such.

Any SAE occurring as a result of a post-study pregnancy which is considered reasonably 
related to the study treatment by the investigator, will be reported to GSK as described in 
Appendix 4. While the investigator is not obligated to actively seek this information in 
former study participants, he or she may learn of an SAE through spontaneous reporting.

SYNOPSIS
Protocol Title: A phase III study (a placebo controlled, randomized, double-blind comparative study 
and an open-label, uncontrolled study) to evaluate the efficacy and safety of GSK1358820 in patients 
with post-stroke upper limb spasticity
Short Title: A phase III study to evaluate the efficacy and safety of GSK1358820 in patients with 
post-stroke upper limb spasticity
Rationale:
GSK1358820, botulinum toxin type A (hereafter referred as the product), is sterile, purified type A 
botulinum neurotoxin complex. Intramuscularly injected botulinum neurotoxin shows muscle relaxant 
effects by blocking the neuromuscular junction and inhibiting release of acetylcholine, a 
neurotransmitter. Since the approval of the product for strabismus and blepharospasm in US in 1989, 
the product is licensed for the treatment of various diseases, which respond to the muscle relaxant 
effects in more than 90 countries (as of Apr 2017).
In Japan, the product is licensed with 8 indications as an ethical drug so far: blepharospasm as a 
first indication in Oct 1996, followed by “hemifacial spasm” in Jan 2000, “spasmodic torticollis” in 
Jun 2001, “talipes equinus associated with lower limb spasticity in pediatric patients two years of age 
and older with cerebral palsy” in Feb 2009, “upper limb spasticity” and “lower limb spasticity” in Oct 
2010, “severe primary maschalephidrosis” in Nov 2012, and “strabismus” in Jun 2015. For “upper 
limb spasticity,” 240 units of the product is approved as a maximum dose per administration. In US, 
as a maximum dose per administration, 400 units of injection of the product have been approved for 
the treatment of upper limb spasticity in adult patients in 2015; therefore, the authorized dose of the 
product between US and Japan is different.
This study is a multicenter, double blind, placebo controlled phase III domestic study and aims to 
evaluate the efficacy and safety of 400 units of the product in patents with post-stroke upper limb 
spasticity. The study was planned to increase the maximum dose per administration in Japan to 400 
units from 240 because the treatment with 240 units of the product, a maximum dose per 
administration, is considered to be insufficient in some patients with post-stroke upper limb spasticity.

Number of Participants:
Approximately 120 subjects (approximately 60 in each group) will be randomized to obtain an 
evaluable subject sample of approximately 100 at Week 48 as subjects with completion of the study。
Treatment Groups and Duration:
Screening Phase (Day -28～Day -1)
Evaluation and screening tests will be performed 28 to 7 days (±3days) before initial injection 
(Day 1) as a starting point. The investigator will decide which arm to be injected during screening 
phase.
Blind Phase (minimum 12 Weeks): Placebo Controlled, Randomized, Double Blind 
Design
Subjects who meet the inclusion criteria will be randomly assigned 1:1 to either the 400 or the 240 
units group. 

In the 400 units group, a total of 240 units of the product will be injected into the muscles 
that act on the finger (including thumb flexors) and wrist flexors, and a total of 160 units 
into the muscles that act on the elbow flexors; a total of 400 units of the product will be 
injected.

In the 240 units group, a total of 240 units of the product will be injected into the muscles 
that act on the finger (including thumb flexors) and wrist flexors. Placebo will be injected 
into the muscles that act on the elbow flexors. A total of 240 units of the product will be 
injected.

If the total dose for the muscles that act on the finger and writs flexors is ensured by 240 units, and 
160 units for the muscles that act on the elbow flexors, the dose can be adjusted at an investigator’s 
discretion based on the subject’s symptoms.
Open-Label Phase (maximum 36 Weeks): Uncontrolled, Open-Label Design
The product of 400 units will be injected in both groups. The product can be injected up to 3 times 
after completion of Part 1 in the blind phase. In the open-label phase, subjects whom the investigator
considers eligible for the injections will be treated. The next injections cannot be performed until the 
eligibility of the subject has been confirmed by the investigator. 
In the open-label phase, the muscle to be injected and the dose will be decided by the investigator 
on the basis of the patient’s symptoms, and a total dose of 400 units of the product will be injected in a 
divided dose. For the muscles that the investigator considers unnecessary to be treated, an injection 
may be skipped. The involving muscle and the dose do not have to be same each time always.
Eligibility Criteria for Injection in and after Part 2
In the open-label phase (Part 2, Part 3, and Part 4), only the subjects whom the investigator 
considers eligible for the study will be injected. The eligibility is evaluated at a study visit after Week 
12 (V5. If a subject does not meet the criteria at V5, the eligibility is evaluated at QRV (Qualification 
for Retreatment Visit). Subjects are considered to be eligible if the following criteria are all satisfied:

1)
At least 12 weeks (84 days) have passed since the preceding dose
2)
Among the finger, wrist or elbow flexors, 2 flexors have at least 2 on the MAS (except only the 
finger and wrist flexors of 2 on the MAS)
3)
Subject who request the injections
4)
Subjects whom an investigator considers an injection of 400 units of the product is appropriate
5)
Subjects who have not experienced serious adverse events (SAE) associated with the injections 
of the product
If subjects meet the criteria of the above 1) to 5) at V5 or QRV, body weight measurement, ECG, 
pulmonary function test, and pregnancy test will be performed to evaluate the following items. If 
subjects meet the following 6) to 8), the subjects will move forward to V1.
6)
Body weight ≥40 kg
7)
Subjects who the investigator considers there are no unacceptable safety concerns [potential 
for serious adverse events, electrocardiogram (ECG) or abnormal pulmonary function
value*] due to 400 U of BOTOX
* This study will use SpO2 (oxygen saturation) as a parameter of pulmonary function. A subject 
who has a 3% reduction from the pre-injection SpO2 (Day 1) in post-injection SpO2 or whose 
SpO2 value is <95% should be referred to a pulmonologist. A subject with pulmonary 
dysfunction due to study treatment also should be referred to a pulmonologist. If the subject is 
considered by the pulmonologist to have no concerns about pulmonary function, the investigator 
should carefully consider whether to start the study treatment.
8)
Women of childbearing potential who have negative pregnancy test result in urine
A pulmonary function test must be performed at V5 even if subjects do not meet the above 1) to 5) in 
accordance with the study operation schedule (SoA).

a.
Test items for screening must be performed from 4 weeks to 1 weeks before Day 1 visit (±3 days).
b.
Eligibility evaluation (Qualification for Retreatment Visit: QRV) will be performed at V5 as a starting point if a subject does not meet the criteria only. The evaluation is performed at a 4-week interval, 
V5 as a starting point, The QRV when a subject meets the criteria will be a same day as the injection in the next treatment period (refer to Figure 1, Figure 2, Figure 3, Figure 4). 
c.
If a subject is evaluated to meet the eligibility for the injection in the blind phase at V5, the subject will move forward to Part 2 in the open-label phase (Namely, V5 in Part 1 and V1 in Part 2 is a same 
day). If the subject does not meet the eligibility, QRV will be performed 4 weeks later, at V5 as s starting point. 
d.
If a subject is evaluated to meet the eligibility at V5 in the open-label phase, the subject will move forward to the next treatment phase (V5 and V1 in the next treatment phase is a same day). If the 
subject does not meet the eligibility, QRV is performed 4 weeks later, V5 as a starting point. If V5 in each treatment phase is at Week 48 after initial injection, V5 will be considered to be completion
visit (FV). However, for the testing items, pre-scheduled tests at V5 and neutralizing antibody tests will be performed. If V5 in Parts 2 and 3 is performed at Week 36 or later, after completion of V5, 
completion visit will be performed at Week 48.
e.
QRV is allowable to perform from initial injection to Week 36. Eligibility evaluation (QRV) will not be performed after Week 36.  
f.
V5 must be performed at least 84 days after V1. 
g.
The acceptable visit windows will be -14 to +4 days if QRV is performed at Week 36.
h.
Must be performed earlier than any other procedures
i.
Must be performed before injection of the product
j.
For inclusion/exclusion criteria, the items to be observed are different between screening phase and Day 1. For details, refer to 6.1. and 6.2.
k.
For MAS evaluation, the items to be evaluated differ depending on the treatment phase. For details, refer to 9.1.1.1.
l.
MAS evaluation will be followed by NRS evaluation. For NRS evaluation, items to be evaluated differ. For details, refer to 9.1.1.2.
m.
Body temperature, heart rate, and blood pressure will be measured as vital signs. 
n.
Women of childbearing potential will be only performed. Serum hCG pregnancy test must be performed at screening, and urine hCG pregnancy test after randomization. The tests can be performed 
beyond the protocol specifications if an investigator considers to be necessary.  
o.
For laboratory test items, refer to 12.2. Attachment 2. Fasting is not required for blood collection. 
p.
Adverse events and serious adverse events collection period will be from the initial injection day (Day 1) to completion visit (FV).
q.
Neutralizing antibody testing is performed 3 times in each subject. The first test will be performed in screening phase, the second is at V5 in the blind phase, and the third is at completion visit.
r.
A subject who withdraws the study before 12 weeks after last injection will be performed. 
s.
Perform if V5 in each treatment phase is at Week 48 after initial injection
t.
Not necessary to perform doubly as V1 assessment if the same assessment is performed at V5 or QRV. If V1 assessment or retreatment cannot be performed on the same day as V5 or QRV, MAS
assessment should be performed again on the day of visit for the V1 assessment.
u.
Evaluation of retreatment is performed only when the dosing conditions (1 to 5) of retreatment evaluation are met. If V1 assessment or retreatment cannot be performed on the same day as V5 or QRV,
body weight, pulmonary function test, electrocardiogram, and pregnancy test should not be performed again on the day of visit for V1 assessment.
v.
V1 assessment in Part 2 or subsequent parts should be performed as a rule on the same day as V5 or QRS (when eligibility was confirmed) of the previous part. If this is not possible, the V1 assessment 
may be performed on another day but within the acceptable visit window.

INTRODUCTION 
3.1.
Study Rationale
GSK1358820, botulinum toxin type A (hereafter referred to as the product) is sterile, purified type 
A botulinum neurotoxin complex. Intramuscularly injected botulinum neurotoxin shows muscle 
relaxant effects by blocking the neuromuscular junction and inhibiting the release of acetylcholine, a 
neurotransmitter. Since the approval of the product for strabismus and blepharospasm in US in 1989, 
the product is licensed for the treatment of various diseases, which respond to the muscle relaxant 
effects in more than 90 countries (as of Apr 2017). 
In Japan, the product is licensed with 8 indications as an ethical drug so far: blepharospasm as first 
indication in Oct 1996, followed by “hemifacial spasm” in Jan 2000, “spasmodic torticollis” in Jun 
2001, “talipes equinus associated with lower limb spasticity in paediatric patients two years of age and 
older with cerebral palsy” in Feb 2009, “upper limb spasticity” and “lower limb spasticity” in Oct 
2010, “severe primary maschalephidrosis” in Nov 2012, and “strabismus” in Jun 2015. For “upper 
limb spasticity,” 240 units of the product is approved as a maximum dose per administration. 
This study is a multicenter, double blind, placebo controlled phase III domestic study in patients 
with upper limb spasticity and aims to confirm the efficacy and safety of 240 units of the product for 
post-stroke upper limb spasticity. The information of 400 units of the product in the study is expected 
to provide beneficial information because the treatment with 240 units of the product with a maximum 
dose per administration is considered to be insufficient in some patients with post-stroke upper limb 
spasticity.
3.2.
Background
Spasticity is a movement disorder that is characterized by increased myotatic reflex and is regarded 
as one of positive signs of the upper motor neuron signs (Kagamihara, 2012; Lance, 1980). Spasticity 
is caused by central nerve system injuries such as stroke, traumatic brain injury, or spinal cord injury 
and chronic neuropathies such as cerebral palsy or multiple sclerosis, etc. Abnormal postures of the 
upper limbs due to spasticity include thumb refraction, a clenched fist deformity, flexion of the wrist 
flexors, pronation of the forearms, flexion of the elbow flexors, and adduction/inner rotation of the 
shoulder flexors (Gracies, 2003; Kinoshita, 2015). 
Spasticity hampers rehabilitation therapy. In addition, limitation of flexors range of motion and 
persistent pain hinder from caregiving and decrease activity in daily life (Grazko, 1995); therefore, 
many of patients with stroke require treatments to ameliorate their dysfunction.
For the treatments of spasticity, rehabilitation therapy, oral medications, phenol blocks, and 
baclofen injections were used until botulinum therapy has been approved as a national health 
insurance coverage. These treatments were commonly challenging because of lack of effects, difficult 
procedures, or invasive interventions. Subsequently, in Oct 2010, the product was approved as a 
botulinum treatment for upper and lower limb spasticity in Japan. Since then, botulinum toxin has 
been used for the treatment of spasticity (Ohsawa, 2013). According to the “Japanese Guidelines for 
the Management of Stroke” (initial version in 2009, revised in 2015) (Ogawa, 2015; Shinohara, 2009), 
which was issued by the Japan Stroke Society, botulinum therapy is recommended for the treatment of 
spasticity as Grade A, and is considered to be effective for relief of upper limb spasticity, increase of 
range of motions in flexors, and reduction of the amount of assistance on daily life.

In Japan, upper limb spasticity, a domestic phase II study involving the finger, wrist, and elbow 
flexors was performed from Dec 2001 through Mar 2003, and a domestic phase III study involving the 
finger and wrist flexors from May 2007 through Dec 2008. Consequently, the product was approved 
for the treatment of upper limb spasticity with a maximum dose of 240 units per administration in Oct 
2010. 
However, subsequently, the injections of the product at 240 units were found to be insufficient for 
the involving muscles because patients with extensive upper limb spasticity require dose adequate to 
inject into many of the involving muscles. Therefore, many medical institutions requested us to 
increase the maximum dose per administration of the product. Moreover, the specified drug-use 
survey from Jun 2011 through Apr 2014 identified that approximately 39% of the patients who use the 
product for upper limb spasticity were injected more than 240 units, a maximum dose per 
administration. The results suggest high patient needs for an increase of the maximum dose per 
administration of the product. 
In US, as a maximum dose per administration, 400 units of injections of the product have been 
approved for the treatment of upper limb spasticity in adult patients in 2015; therefore, the authorized 
dose between US and Japan is different. 
Based on these background, the study was planned to evaluate the efficacy and safety of 400 units 
of the product for upper limb spasticity in order to increase the maximum dose per administration to 
400 units. 
The study was planned based on the regulatory advice by the Pharmaceuticals and Medical Devices 
Agency (PMDA).

Measures for risk minimization
Investigational product: GSK1358820
Hypersensitivity
Serious and/or immediate hypersensitivity reactions
(anaphylaxis, serum sickness, urticarial, soft tissue 
edema, or dyspnea, etc.) have been rarely reported. 
Patients who previously experienced allergic reactions 
due to botulinum toxin type A, an additive agent of 
sodium chloride, or human serum albumin are 
excluded from enrolment. Upon written informed 
consent process, subjects will be explained that any 
urticarial, swelling face, throat swelling, wheezing, 
dizziness, or dyspnoea should contact their
investigator. 
Pre-existing neuromuscular disorder
Patients with neuromuscular junction diseases 
(myasthenia gravis, Lambert-Eaton myasthenic 
syndrome etc.) may increase the sensitivity to the 
product, resulting in excessive muscular weakness. 
For patients with myasthenia gravis, Eaton-Lambert 
syndrome (ELS), amyotrophic lateral sclerosis, or a 
serious disease and who use a concomitant drug (s) 
which may inhibit neuromuscular function, exclusion 
criteria will be set, and those patients will be excluded 
from enrolment in the study (refer to 6.2.1). 
distant spread of toxin
Adverse drug reactions in the remote muscles, except 
but the injected site, have been rarely reported. The 
adverse drug reactions include muscular weakness, 
constipation, dysuria, swallowing difficult, and non-
accidental entering of food or fluid in the lungs not via 
the stomach, but the trachea (pneumonia may occur). 
The patients who received the product at a higher dose 
are considered likely to have increased risks for these 
adverse drug reactions. 
In this study, a high dose of 400 units of the product 
will be injected. Therefore, the subjects will be 
followed up after 2, 4, 6, and 12 weeks of injection. 
The safety of the subjects will be observed carefully.
Use of at least one of the following guide tools 
(electromyogram, electrical stimulator, or 
ultrasonography) will be essential in the blind phase to 
ensure identification of the exact site of injection.

Important identified risks
Reports suggesting risks/ Outlines of rationale
Measures for risk minimization
Immunogenicity, drug resistance, antibody production The important cause of neutralizing antibody 
production has not been fully clarified. A few studies 
suggested that the injection of the product at short 
intervals or at a high dose may lead to increased rate 
of antibody production[Jankovic, 2006; Klein, 2002]. 
Neutralizing antibody production against botulinum 
toxin type A may lead to inactivation of the biological 
activity of the product, resulting in decreased 
therapeutic effects of the product.
In this study, patients who were considered likely to 
have neutralizing antibody production based on the 
previous treatment experience of botulinum toxin type 
A will be excluded from enrolment in the study 
(Exclusion Criteria 6.2.1).
In addition, treatment schedule in the study was set to 
ensure at least a 12-week dosing interval. 
Other (If applicable)
Medication error (preparation with lidocaine)
One fatal case due to anaphylaxis has been reported. 
In this case, the patient died after 100 units of an 
injection of the product that prepared inappropriately 
with 5 mL of 1% lidocaine. The causal relationship of 
death to the product and lidocaine, or both has been 
unknown. 
In this study, the product will be prepared
appropriately with 0.9% normal saline. The 
preparation method will be described on the study 
reference manual (SRM).

Benefit Assessment
In patients with post-stroke upper limb spasticity, currently, the product is approved to inject up to 
240 units per administration in Japan. However, in patients with extensive upper limb spasticity, the 
treatment effects of the product are presumed to lack because of the dose limitation.
In US, the efficacy and safety of the product up to 400 units per dose for patients with upper limb 
spasticity is confirmed, and the clinical use of the product has been approved. The injections of 400 
units of the product in this study are expected to increase injectable sites and enhance the treatment 
effects in Japanese patients with upper limb spasticity, who did not have great benefits from 240 units 
of the product.
If a subject is assigned to the 240 units group in Part 1 and meets the eligibility criteria for injection in 
the open-label phase, 400 units of the product will be injected in and after Part 2. Therefore, all the 
subjects who participate in this study are given the opportunity to receive 400 units of the product 
(Refer to “5. STUDY DESIGN”). 
3.3.3.
Overall Benefit:Risk Conclusion
The known potential risks in the product is justified by the benefits which would provide for the 
patients with post-stroke upper limb spasticity, given the safety measures to minimize risks in subjects 
who enrol in the study.

Figure 5   Study Design
In this study, the efficacy of 400 units of the product at Week 6 is evaluated, comparing to that of 
240 units, and improvement tendencies are also evaluated in patients with post-stroke upper limb 
spasticity. The improvement will be defined as at least 1 reduction on the MAS score from baseline (a 
measurement value before injection of Day 1). The responder rate (the rate of the subjects that MAS 
score is reduced at least 1 from baseline) in the elbow flexors at Week 6 is set as an endpoint. As a 
point estimate, if the responder rate in the 400 units group outweighs that in the 240 units group, 
improvements tendencies will be considered to be positive. 
For injection, use of the following any one of the tools: EMG, electrical stimulator, or 
ultrasonography, is recommended to ensure identification of the exact injection site. In the blind phase, 
use of at least one of the following tools: EMG, electrical stimulator, or ultrasonography, will be 
essential to ensure identification of the muscle to be injected correctly. 
5.1.1.
Screening Phase (up to 4 weeks) 
Evaluation and screening tests will be performed 28 days to 7 days (+3 days) before initial injection 
(Day 1) as a starting point. The investigator will decide which arm to be injected during screening 
phase. Throughout the study period, the arm, which is decided to be injected at screening phase will 
be involved during the injections and evaluations, unless clearly specified otherwise by the sponsor.

Blind Period (minimum 12 Weeks): Placebo Controlled, Randomized, Double 
Blind Design
Subjects who meet the inclusion criteria will be randomized 1:1 to either the 400 units or the 240 
units group. 

In the 400 units group, a total of 240 units of the product will be injected into the muscles 
that act on the finger (including thumb flexors) and wrist flexors, and a total of 160 units 
into the muscles that act on the elbow flexors; a total of 400 units of the product will be 
injected.

In the 240 units group, a total of 240 units of the product will be injected into the muscles 
that act on the finger (including thumb flexors) and wrist flexors. Placebo will be injected 
into the muscles that act on the elbow flexors. A total of 240 units of the product will be 
injected.
If the total dose for the muscles that act on the finger and writs flexors is ensured by 240 units, and 
160 units for the muscles that act on the elbow flexors, the dose can be adjusted at an investigator’s 
discretion based on the subject’s symptoms. (Refer to “7.1. Treatments Administered” Table 2).
5.1.3.
Open-Label Phase (maximum 36 weeks): Uncontrolled, Open-Label Design
The product of 400 units will be injected in both groups. The product can be injected up to 3 times 
after completion of Part 1 in the blind phase. In the open-label phase, subjects whom the investigator 
considers eligible for the injection will be treated (Refer to 5.1.3.1. Eligibility Criteria for Injection in 
and after Part 2). The next injection cannot be performed until the eligibility of the subject has been 
confirmed by the investigator (Refer to 5.1.3.1. Eligibility Criteria for Injection in and after Part 2).
In the open-label phase, the muscle to be injected and the dose will be decided by the investigator
based on the patient’s symptoms, and a total dose of 400 units of the product will be injected in a 
divided dose (Refer to "7.1. Treatments Administered” on Table 3). For the muscles that the 
investigator considers unnecessary to be treated, an injection may be skipped. The involving muscle 
and the dose do not have to be same each time always.
5.1.3.1.
Eligibility Criteria for Injection in and after Part 2
In the open-label phase (Part 2, Part 3, and Part 4), the subjects whom the investigator considers
eligible for the injections in the open-label phase only will be treated. The eligibility is evaluated at a 
study visit after Week 12 (V5, if a subject does not meet the eligibility criteria, the evaluation will be 
performed at QRV (Qualification for Retreatment Visit). A subject will be considered as eligible when 
he or she meets all the criteria. The eligibility evaluation will be performed after completion of Part 1 
in the blind phase, between Week 12 to Week 36. If a subject does not meet the eligibility at Week 36, 
subsequent evaluation will not be performed, and the product cannot be given (refer to Figure 1, 
Figure 2, Figure 3, and Figure 4).

5.4.
Scientific Rationale for Study
The study design was set to evaluate the efficacy and safety of 400 units of the product in patients 
with post-stroke upper limb spasticity. The primary endpoints employed the responder rate of the 
MAS score in the elbow flexors. The reasons for employing MAS score as an indicator include that 
MAS is highly reliable for evaluation of upper limb spasticity (Bohannon, 1987; Mutlu, 2008); 
especially, for evaluation of spasticity in the elbow flexors in the upper limbs (Gregson, 2000; Sloan, 
1992). 
Screening Phase
The screening phase up to 28 days before initial injection was set in order to confirm subjects meet 
the inclusion criteria and none of the exclusion criteria, and assess the condition of subjects at baseline. 


2017N315029_02
CONFIDENTIAL
207660
30
However, measurements of laboratory parameters at screening phase should be completed by 4 days 
before Day 1 (Day -28 to -4). 
Treatment Phase 
In Part 1, a double blind comparative study was set to compare the efficacy of the product of 400 
units to 240 units, the currently approved dose for upper limb spasticity. In the blind phase, 240 units 
of the product will be injected into the muscles that act on the finger (including the thumb)/wrist 
flexors, and 160 units (the 400 units group) or placebo (the 240 units group) for the muscles that act 
on the elbow flexors. The improvement tendencies in the efficacy between the 240 units group, the 
total dose, and the 400 units groups will be compared by evaluating the responder rate tendencies on 
the MAS score in the elbow flexors in a blinded manner. In the previous confirmatory study (108509 
study) for approval of the product for upper limb spasticity, the elbow flexors were not involved. 
Therefore, in this study, the responder rate on the MAS score in the elbow flexors was decided to 
compare as the placebo group. 
Actually, in medical institutions, the product is injected into the whole upper limb, including the 
shoulder flexors. In addition, the dose for each muscle is decided at an investigator’s discretion. 
Previous studies reported that botulinum injections into the pectoralis major and teres major muscle 
relieved pain in patients with hemiplegia (Marciniak, 2012) and injections into the sub-scapula 
improved passive range of motion (Yelnik, 2007). Therefore, in and after Part 2 in the open-label 
phase, the product will be allowed to be injected not only into the muscles that acts to the finger 
(including the thumb), wrist, and elbow flexors, but also the muscles that act on the shoulder flexors, 
where applicable, enabling an investigator to decide the dose for each muscle. In addition, the study 
design included safety evaluation of the product at Week 48 after initial injection in all subjects as far 
as possible for safety evaluation purposes of 400 units. 
5.5.
Dose Justification
The product of 400 units is a maximum dose for upper limb spasticity, which was approved by the 
U.S. Food and Drug Administration (FDA), and this suggests that the efficacy and safety profiles are 
favourable. Evaluation of the efficacy and safety of 400 units of the product provides beneficial 
information in Japanese patients with severe post-stroke upper limb spasticity, who are considered 
injections of 400 units of the product are necessary. 
The dose of 240 units of the product, the controlled group, in the blind phase (Part 1) is the current 
authorized dose (a maximum dose per administration) for upper limb spasticity in Japan. In this study, 
the 240 units group was set as the control group in order to evaluate improvement tendencies, 
comparing the efficacy of 240 units of the product, the current approved dose, to that of 400 units of 
the product.

Method of Treatment Assignment
After completion of all evaluations at screening phase/initiation of the blind phase, the subjects who 
met the inclusion criteria and none of the exclusion criteria will be given their randomization number
at a case registry center and randomized to either the 240 or 400 units group. The assigned 
randomization number cannot be re-used. The table of the allocation will be prepared via a computer 
in GSK, using the RandAll systems. 
Based on the MAS score (3 or 4) in the elbow flexors, subjects will be stratified at the time of 
randomization. 
The subjects who meet the eligibility for the injections in the open-label phase can move forward to 
the open-label phase and be injected (Refer to section 5.1.3). In the open-label phase, 400 units of the 
product will be given to all subjects. Other detailed information will be described on SRM.

the emergency treatment disclosure is required will be prepared. In response to the request of 
disclosure, unblinding procedures are performed for the requested drug only.
The unblinded subjects by the investigator will discontinue participation in the study. In addition, 
the major reasons for discontinuation (the event(s) or condition led to unblinding) will be described on 
case report form (CRF). 
The Global Clinical Safety and Pharmacovigilance (GCSP) of the sponsor may disclose the 
assigned treatment in the subject, who experienced serious adverse events. For serious adverse events 
requiring emergency report to the regulatory authority, a copy of an emergency report on the assigned 
treatment of the subject may be sent to the study involving investigator in accordance with the 
regulations, policy of the sponsor, or both.  
7.5.

8.2.1.
Liver Chemistry Stopping Criteria
A set of criteria for study discontinuation and follow-up investigation based on hepatic function 
test (in reference to FDA premarketing clinical liver safety guidance) is specified herein to ensure the 
safety of subjects and to evaluate the causes of hepatic events. The guidelines related to this protocol 
are based on the FDA premarketing clinical liver safety guidance: 
http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/UCM1
74090.pdf.
The investigator should consider discontinuing the study treatment upon discovery of liver function 
test abnormal, and if the subject is applicable to any of the symptoms presented in the algorithm, or 
such discontinuation is determined to be the best choice for the subject as judged by the investigator.
Algorithm A: Phase III-IV Liver Chemistry Stopping and Increased Monitoring Algorithm

8.2.2.
QTc Stopping Criteria

For a decision on a subject's eligibility or study discontinuation, the same method for 
correction of QT interval must be used in the subject throughout the study, and must not be 
changed once the subject is enrolled. 

For instance, if a subject is enrolled based on QTcB, decisions on the subject's 
withdrawal must be made based on QTcB. 

The method used for correction of QT interval pertinent to the enrollment of a subject 
must be used for all QTc data to be collected throughout the study for the data analysis 
on the subject; provided that such rule is not applicable to ECG intended to ensure 
safety and also ECG not defined in the protocol. 

QTc should be determined based on a single measurement of ECG or the mean of ECG 
measured at 3 timepoints in a short period of time (e.g., 5 to 10 minutes). If abnormality is 
detected in a single measurement, ECG should be measured again, this time, at 3 timepoints. 

The lowest value of QTc cannot be used for a decision to withdraw a subject. 
Refer to the schedule of assessment (SoA), completion visit (FV), for the details of data to be 
collected at the discontinuation of study treatment. Discontinue this study if the mean ECG is 
applicable to any of the following conditions:

QTc >500 msec or uncorrected QT >600 msec

Change in QTc from baseline >60 msec
The following withdrawal criteria should be applied for subjects with bundle branch block: 
Baseline for subjects with bundle branch block

8.2.3.
Treatment discontinuation due to treatment-related SAE
A subject should be withdrawn from this study if treatment-related serious adverse event has 
occurred.
8.2.4.
Treatment discontinuation due to pregnancy
A female subject who become pregnant during this study must be withdrawn from the study.
8.2.5.
Withdrawal of subjects who start receiving prohibited medications or 
therapies
If a prohibited medication or therapy (See section 7.7.2.) needs to be started during the study, the 
subject must be withdrawn from this study; in which case, the subject must make the study completion 
visit (FV) before starting the prohibited medication or therapy.

8.2.6.
Prohibition of treatment resumption
Study treatment must not be resumed in subjects who are once withdrawn from this study for a 
reason associated with hepatic function test, QTc, treatment-related serious adverse event, pregnancy, 
or commencement of a prohibited medication or therapy.
8.3.
Lost to follow up
A participant will be considered lost to follow-up if he or she repeatedly fails to return for scheduled 
visits and is unable to be contacted by the study site. 
The following actions must be taken if a participant fails to return to the clinic for a required study 
visit: 

The site must attempt to contact the participant and reschedule the missed visit as soon as 
possible and counsel the participant on the importance of maintaining the assigned visit 
schedule and ascertain whether or not the participant wishes to and/or should continue in the 
study.

Before a participant is deemed lost to follow up, the investigator or designee must make 
every effort to regain contact with the participant (where possible, 3 telephone calls and, if 
necessary, a certified letter to the participant’s last known mailing address or local 
equivalent methods). These contact attempts should be documented in the participant’s 
medical record. 

Should the participant continue to be unreachable, he/she will be considered to have 
withdrawn from the study with a primary reason of lost to follow-up. 
9.
STUDY ASSESSMENTS AND PROCEDURES

Study procedures and their timing are summarized in the SoA. 

Protocol waivers or exemptions are not allowed. 

Immediate safety concerns should be discussed with the sponsor immediately upon 
occurrence or awareness to determine if the participant should continue or discontinue study 
treatment. 

Adherence to the study design requirements, including those specified in the SoA, is 
essential and required for study conduct. 

All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria. The investigator will maintain a screening log to 
record details of all participants screened and to confirm eligibility or record reasons for 
screening failure, as applicable. 

Procedures conducted as part of the participant’s routine clinical management (eg, blood 
count) and obtained before signing of ICF may be utilized for screening or baseline 
purposes provided the procedure met the protocol-specified criteria and was performed 
within the time frame defined in the SoA.

Modified Ashworth Scale (MAS)
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator will use MAS (Table 5) to 
evaluate the level of spasticity. MAS should be measured and evaluated by the investigator, 
physiotherapist, or occupational therapist who has been given the training as an assessor. 
The test should be performed on sitting position throughout the study. The affected parts should be 
extended as fast as possible to grade the flexor muscle tones. The final assessment will be made by the 
investigator in consideration of the information from physiotherapist or occupational therapist. The 
assessor should in principle remain unchanged throughout the study period.


MAS measurement as inclusion criteria (Screening and Day 1)
The subject's wrist or fingers and elbow should all be evaluated as inclusion criteria. Subjects 
meeting the eligibility and randomized should be evaluated for MAS at Visit 1 of Treatment Period 1
on the same day; provided that measurement may be performed only once if the affected part to be 
evaluated is the same. The detail of inclusion criteria are shown in 6.1.

MAS measurement during the blinded period
The subject's wrist, fingers, thumb and elbow should all be evaluated during the blinded period. 
Likewise, the subject's wrist, fingers, thumb and elbow should all be evaluated for MAS at Visit 5 and 
QRV of the blinded period. Subjects meeting the eligibility and transferred to the open-label period 
should be evaluated for MAS at Visit 1 of Treatment Period 2 on the same day; provided that 
measurement may be performed only once if the affected part to be evaluated is the same. Meanwhile, 
MAS needs to be evaluated again if the affected part to be evaluated is not the same. In subjects who 
have received no injection to any muscles affecting the thumb, MAS measurement on the thumb will 
not be performed.

MAS measurement during the open-label period
During the open-label period, MAS should be evaluated for the flexors at which the muscle given 
the study treatment functions (fingers, thumb, wrist, elbow, fore-arm) (Table 6). If the subject is 
determined to be eligible, the V5/QRV and V1 would be on the same day, and therefore, the MAS

measured at V5/QRV of the previous treatment period should not be measured again on V1; the 
measurement on V5/QRV should be used for the assessment (Figure 6). MAS on flexors to be newly 
assessed on V1 should be evaluated before dose on V1. The MAS on the shoulder should be evaluated 
comprehensively for the adductor and invertor.

NRS measurement during the blinded period
During the blinded period, the severity of pain in the elbow flexors will be evaluated. 

NRS measurement during the open-label period
During the open-label period, a major part with pain [specify 1 part from among fingers, thumb, 
wrist, elbow, fore-arm (pronate), and shoulder] will be evaluated for the severity of pain on Visit 1. 
The part to be evaluated does not have to be the same within each treatment period, but should be the 
same part as that evaluated for MAS. 
9.1.1.3.
Disability Assessment Scale (DAS)
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator (or subinvestigator) will 
use the 4 disability assessment parameters presented in Table 7 and evaluate all of them based on the 
scale presented in Table 8. Before starting the study treatment, the investigator shall discuss with the 
subject, and select and evaluate 1 parameter agreed with the subject as the "main assessment 
parameter." The assessor should in principle remain unchanged throughout the study period. The main 
assessment parameter should also remain unchanged throughout the study period.
Table 7    Disability assessment parameters

Clinical Global Impression of Change (CGI) assessed by an investigator
The investigator (or subinvestigator) will evaluate CGI according to "2. SCHEDULE OF 
ACTIVITIES (SoA)”; Changes in spasticity (Clinical Global Impression) from baseline (V1 in each 
treatment phase) will be evaluated by 9 grades as shown in Table 9.
The investigator shall also consider the subject's clinical symptoms and adverse events pertinent to 
the assessment of CGI. Also, the therapeutic effect of the product injected in the subject's fingers, 
wrist, and elbow should be taken into an account. The assessor should in principle remain unchanged 
throughout the study period.

Clinical Global Impression of Change (CGI) assessed by a patient
According to "2. SCHEDULE OF ACTIVITIES (SoA))" the investigator (or subinvestigator) will 
use Table 9 to record subject-reported CGI. The investigator shall interview each subject on changes 
in spasticity from predose, and the subject will evaluate it using Table 9.
9.1.1.6.
Time to patient-reported onset of spasticity symptom relief (Visit 2):
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator (or subinvestigator) will 
record the time to alleviation of spasticity reported by subjects. The investigator shall ask the subject 
whether the product was effective on the spasticity, and if the subject's response to the question is 
positive, ask him/her "how many days did it take for the therapeutic effect to appear after the current 
dose?" and record the number of days.
9.1.1.7.
Patient-reported benefit of injection (Visits 3, 4, and 5)
According to "2. SCHEDULE OF ACTIVITIES (SoA)" the investigator (or subinvestigator) will 
record the efficacy of treatment reported by subjects. The investigator shall ask, "Was the product
effective?" and the subject shall respond either by "Yes" or "No."

9.2.
Adverse events
Definitions of adverse events and serious adverse events (SAE) are as specified in Appendix 4.
The investigator or a person assigned by the investigator is responsible for detecting, recording, and 
reporting events that match the definitions of adverse events and SAEs, and also, responsible for 
follow-up investigations on SAEs, as well as events related to the study drug or this study, and events 
that resulted in treatment discontinuation or subject withdrawal (See section 8). 
9.2.1.
Period subject to collection of data related to adverse events and SAEs, and 
the frequency of such data collection

All SAEs will be collected from the start of treatment until Final Visit at the time points 
specified in the SoA (Section 2). 

All AEs will be collected from the start of treatment until Final Visit at the time points 
specified in the SoA (Section 2). 

Medical occurrences that begin before the start of study treatment but after obtaining 
informed consent will be recorded on the Medical History/Current Medical Conditions 
section of the case report form (CRF) not the AE section. 

All SAEs will be recorded and reported to the sponsor or designee within 24 hours, as 
indicated in Appendix 4. The investigator will submit any updated SAE data to the sponsor 
within 24 hours of it being available. 

Investigators are not obligated to actively seek AEs or SAEs in former study participants. 
However, if the investigator learns of any SAE, including a death, at any time after a 
participant has been discharged from the study, and he/she considers the event to be 
reasonably related to the study treatment or study participation, the investigator must 
promptly notify the sponsor. 

The method of recording, evaluating, and assessing causality of AEs and SAEs and the 
procedures for completing and transmitting SAE reports are provided in Appendix 4.
9.2.2.
Method used to detect adverse events and SAEs
Care will be taken not to introduce bias when detecting AE and/or SAE. Open-ended and non-leading 
verbal questioning of the participant is the preferred method to inquire about AE occurrence.
9.2.3.
Follow up on adverse events and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each participant at 
subsequent visits/contacts. All SAEs will be followed until the event is resolved, stabilized, otherwise 
explained, or the participant is lost to follow-up (as defined in Section 8.3). Further information on 
follow-up procedures is given in Appendix 4.
9.2.4.
Regulatory requirements of SAE reporting

Prompt notification by the investigator to the sponsor of a SAE is essential so that legal 
obligations and ethical responsibilities towards the safety of participants and the safety of a 
study treatment under clinical investigation are met. 


2017N315029_02
CONFIDENTIAL
207660
52

The sponsor has a legal responsibility to notify both the local regulatory authority and other 
regulatory agencies about the safety of a study treatment under clinical investigation. The 
sponsor will comply with country-specific regulatory requirements relating to safety 
reporting to the regulatory authority, Institutional Review Boards (IRB)/Independent Ethics 
Committees (IEC), and investigators. 

Investigator safety reports must be prepared for suspected unexpected serious adverse 
reactions (SUSAR) according to local regulatory requirements and sponsor policy and 
forwarded to investigators as necessary. 

An investigator who receives an investigator safety report describing a SAE or other 
specific safety information (eg, summary or listing of SAE) from the sponsor will review 
and then file it along with the Investigator’s Brochure and will notify the IRB/IEC, if 
appropriate according to local requirements. 
9.2.5.
Cardiovascular events and death
For any cardiovascular events detailed in Appendix 4 and all deaths, whether or not they are 
considered SAEs, specific Cardiovascular (CV) and Death sections of the CRF will be required to be 
completed. These sections include questions regarding cardiovascular (including sudden cardiac 
death) and non-cardiovascular death. 
The CV CRFs are presented as queries in response to reporting of certain CV MedDRA terms. The 
CV information should be recorded in the specific cardiovascular section of the CRF within one week 
of receipt of a CV Event data query prompting its completion. 
The Death CRF is provided immediately after the occurrence or outcome of death is reported. Initial 
and follow-up reports regarding death must be completed within one week of when the death is 
reported.
9.2.6.
Pregnancy

Details of all pregnancies in female partners of male participants will be collected after the 
start of study treatment and until Final Visit. 

If a pregnancy is reported, the investigator should inform GSK within 24 hours of learning 
of the pregnancy and should follow the procedures outlined in Appendix [X]. 

Abnormal pregnancy outcomes (eg, spontaneous abortion, fetal death, stillbirth, congenital 
anomalies, ectopic pregnancy) are considered SAE. 
9.3.
Management of overdosage
A dosage of the product exceeding 400 units within 24 hours shall be considered as overdosage in 
this study. Overdosage may cause excessive pharmacodynamic responses such as hyposthenia, 
muscular paralysis, and other localized adverse reactions. Symptoms and signs may not immediately 
appear following dose. Moreover, blepharoptosis, dysarthria, dysphagia, dyspnea, myasthenia, and 
other events suspected to be an effect on other muscles distal to the treated muscle have been reported 
overseas. If such a symptom appears, the subject should be carefully monitored, and given appropriate 
interventions, if necessary with hospitalization. Also, supportive therapies such as artificial breathing 
should be considered for respiratory symptoms.


2017N315029_02
CONFIDENTIAL
207660
53
Upon confirmation of overdosage, the investigator should;
1.
Contact the Medical Monitor immediately.
Carefully monitor the adverse event/SAE, and laboratory abnormalities in the subject for at least 4 
weeks; and 
Document the quantity of the excess dose as well as the duration of the overdosing in the CRF.
The investigator shall discuss with the sponsor's medical monitor on the clinical assessment of the 
subject, and upon which, decide whether or not to discontinue the study treatment.
9.4.
Safety assessments
Assessment timepoints for all safety parameters are as shown in SoA.
9.4.1.
Physical examination
Physical examination (complete version): Only during screening

The head and neck, skin, lungs, cardiovascular system, abdominal region (liver and spleen), 
gastrointestinal system, lymph node, and nervous system should be examined, and the 
results thereof should be recorded; these organs should be examined for the 
presence/absence of pre-existing conditions and abnormal findings, and if there is any 
suspected abnormality, detailed examinations should be performed. 

The pulmonary function test should be conducted in details if any sign of pulmonary 
impairment is found. For the pulmonary function test, spirometry by pulmonologists is 
recommended. 
Physical examination (simplified version): To be conducted only if an eligibility criterion is not met 
during the open-label period. 

At least, the lungs, cardiovascular system, and abdominal region (liver and spleen) should 
be examined, and the results thereof should be recorded. 

The investigator should pay attention to clinical signs and symptoms related to a history of 
serious disease. 
The physical examinations should be performed by doctors in accordance with the standard clinical 
guidelines of each study site.
9.4.2.
Vital signs

For the vital signs, body temperatures (oral, intra-aural, or axillary fossa), systolic/diastolic 
blood pressures, and pulse rates should be measured in a semi-recumbent position after a 5-
minute rest. If measurement in a semi-recumbent position is difficult, measurement in 
another position (e.g., sitting) is acceptable. In this case, however, the measurement should 
be performed always in the same position during the study period.

If a temperature is to be measured orally, the subject must refrain from eating food or 
drinking beverage within 5 minutes before the measurement. The method for the 
measurement of body temperature must remain the same throughout the study. 


2017N315029_02
CONFIDENTIAL
207660
54

The blood pressures and pulse rates should be measured with an automated device. A 
manual method may be used only if there is no automated device available for use. 
9.4.3.
Height and weight
The standard clinical guidelines of each study site should be followed.
9.4.4.
Pulmonary test

Refer to SoA for the timepoints and frequency of testing.

If post-injection SpO2 is decreased by 3% or more from the baseline (pre-injection on Day 
1) or a SpO2 value is <95%, medical examination by pulmonologist is required. A subject 
with pulmonary dysfunction due to study treatment based on the investigator's opinion
will be referred to a pulmonologist as well.

If a medical institution has no pulmonologist, visit other hospitals for medical examination 
by specialists. For the pulmonary function test, spirometry by pulmonologists is 
recommended.

If a subject is referred to a pulmonologist and considered to have no concerns about 
pulmonary function, the investigator should carefully consider whether to start or continue 
study treatment.
9.4.5.
ECG

QTc should be determined based on a single measurement of ECG or the mean of ECG 
measured at 3 timepoints in a short period of time (e.g., 5 to 10 minutes). 

An automated measurement and manual re-interpretation in accordance with SoA should be 
used to collect data on the heart rates, PR, QRS, QT, and QTc interval. Refer to section 
8.2.2. for QTc-related treatment discontinuation standard, and additional QTc to be 
measured as required. 

Each interval between timepoints for the measurement of ECG should be minimized as 
much possible (within 2 minutes). The measurement of ECG should be performed 3 times 
consecutively and completed within 5 to 10 minutes. 
9.4.6.
Neutralizing antibody test
The investigator shall draw blood for neutralizing antibody samples in accordance with the study 
schedule. The neutralizing antibody will be measured collectively by central laboratories designated 
by GSK (Intertek Pharmaceutical Services Co. and Pacific BioLabs Co.). The screening samples will 
be retained temporarily by the central laboratories, and then, upon retrieval of samples from all 
subjects, will be collected and tested by Intertek for screening. Samples tested positive at Intertek will 
be separately sent to Pacific BioLabs for retest to finalize the results of neutralizing antibody test. The 
above procedures shall also be taken for samples collected for Week 12 visit during the blinded period, 
and upon completion of study treatment in all subjects.

9.4.7.
Clinical Safety Laboratory Assessments

Refer to Appendix 2 for the list of clinical laboratory parameters that should be tested, and 
to SoA for the timepoints and frequency of testing. 

The investigator must review the laboratory report, document this review, and record any 
clinically relevant changes occurring during the study in the AE section of the CRF. The 
laboratory reports must be filed with the source documents. Clinically significant abnormal 
laboratory findings are those which are not associated with the underlying disease, unless 
judged by the investigator to be more severe than expected for the participant's condition.

All laboratory tests with values considered clinically significantly abnormal during 
participation in the study should be repeated until the values return to normal or baseline or 
are no longer considered significantly

If such values do not return to normal/baseline within a period of time judged reasonable by 
the investigator, the etiology should be identified and the sponsor notified.

All protocol-required laboratory assessments, as defined in Appendix 2, must be conducted 
in accordance with the laboratory manual and the SoA.

If a result of clinical laboratory test not scheduled in the protocol is obtained by a study site, 
which requires a change in the patient management, or is determined to be clinically 
important by the investigator, that is SAE, adverse event, an event requiring dose 
modification, or any other relevant event, the record thereof must be documented in the 
CRF. 

Follow-up investigation may be performed at any time during the study as determined to be 
necessary by the investigator, or required by the Japanese regulation.

10. STATISTICAL CONSIDERATIONS
10.1.
Sample Size Determination
This study is not intended to verify a statistical hypothesis, but is rather intended to verify that the 
responder rate in the 400 units group exceeds that in the 240 units group, and for which, about 120 
subjects (60 in each treatment group) are to be enrolled.
During Treatment Period 1 of this study, 160 units of the product will be administered in the muscle 
which affects the elbow; thus, the sample size was determined in reference to an overseas phase III 
study (Study 127) in which a similar dosage as this study (150 units) was administered in the muscle 
which affects the elbow. The responder rate in the elbow at Week 6 of the initial dose in Study 127 
was 72.2% and 47.1% in the product 300 units group (150 units in the muscle which affects the elbow 
flexors) and placebo group, respectively. The number of subjects in the intention-to-treat (ITT) 
population was small in both the product 300 units group and placebo group of Study 127, which was 
18 subjects each; thus, considering the uncertainty of the results of Study 127, the responder rates in 
the product 400 units and 240 units groups in this study were conservatively assumed to be 70.0% and 
50.0%, respectively. Assuming that the sample size is 60 subjects in each group, the power of test to 
detect an intergroup difference in the responder rates would be about 62% with a two- sided
significance level of 5% while the probability of the responder rate in the product 400 units group to 
exceed that in the product 240 units group as a point-estimate would be 98%.
With about 120 subjects enrolled, 100 subjects are expected to complete Week 48 of the initial dose.
10.2.
Populations for Analyses
Populations for statistical analyses in this study are defined as follows.
Population
Description
ITT
All subjects randomized in the study and had at least 1 post-baseline 
efficacy assessment: ITT is the primary efficacy analysis population, and 
the subjects will be analyzed in line with the randomized treatment group. 
Safety 
All subjects randomized in the study and received study treatment at least 
once: The subjects will be analyzed based on the treatment actually given. 
10.3.
Statistical Analyses
10.3.1.
Efficacy Analyses
This study is not intended to verify a statistical hypothesis; thus, there will be no statistical test.
All of the efficacy analyses will be performed on the ITT population separately for the blinded 
period and the open-label period.

Endpoints
Statistical Analysis Methods
Primary
The primary endpoint is the proportion of subjects whose MAS score on the elbow at 
Week 6 of the initial dose decreased by at least 1 level from the baseline (responder rate). 
The primary endpoint will be calculated as the proportion of subjects whose MAS score 
decreased by at least 1 level from the baseline in the ITT population. Also, a 95% 
confidence interval of the intergroup difference in the responder rate will be computed. 
Subjects with no MAS score available at Week 6 will not be counted as subjects whose 
MAS score decreased by at least 1 level from the baseline (that is, counted in as non-
responder). 
The MAS scores, 0, 1, 1+, 2, 3, and 4 will be encoded to 0, 1, 2, 3, 4, and 5, respectively, 
for the analysis purpose. 
Secondary
Unless specified otherwise, the data up to Week 12 of treatment will be summarized for 
each repeated dose during the open-label period. 
During the blinded period, a mixed model for repeated measurement (MMRM) will be 
used for the analysis on the endpoints specified below, and the least-square mean and 95% 
confidence interval will be calculated. The details of the model will be described in the 
statistical analysis plan. For the open-label period, only a summary statistics will be 
performed for each treatment group. Missing values will not be imputed. 
Change in MAS score in the fingers, thumb, wrist, and elbow from the baseline
Change in Disability Assessment Scale (primary endpoint) from the baseline 
The proportion of subjects in whom MAS score in the fingers, thumb, wrist, and elbow 
decreased by at least 1 level from the baseline (responder rate) during the blinded period 
will be analyzed with the same method as that for the primary endpoint. For the open-
label period, the denominator to be used for the calculation of responder rate shall be the 
number of subjects in each subgroup stratified by the number of injections given, not the 
ITT population. Also, a 95% confidence interval of the intergroup difference in the 
responder rate will not be calculated. 
Exploratory
Time to patient-reported onset of spasticity symptom relief will be evaluated for subjects 
who reported alleviation of spasticity at in 2 weeks postdose. The number of days from 
dose to the alleviation of spasticity will be summarized for each treatment group. 
Clinical Global Impression of Change (CGI) assessed by an investigator, CGI assessed by 
a patient, and Patient-reported benefit of injection will be summarized for each treatment 
group. Missing values will not be complemented. 
Other details will be specified in the statistical analysis plan. 
10.3.2.
Safety Analysis
Safety analyses will all be performed on the safety population separately for the blinded and open-
label periods.

Secondary
Adverse events that occurred in the overall study period, blinded period, and open-label 
period will be summarized for each treatment group. For the blinded period, 2 patterns of 
analyses on adverse events will be performed; one is on adverse events that occurred 
between the initial dose and the first dose in the open-label period (or at the completion 
of study if no dose is given in the open-label period or at the study withdrawal), and 
another one is on adverse events that occurred within 84 days from the initial dose. 
Adverse events will be summarized separately for SOC (system organ class) and PT 
(preferred term). Also, adverse events related to study treatment, adverse events that 
resulted in discontinuation, adverse events by subgroups stratified by severity, and 
serious adverse events will be summarized. 
Laboratory findings and vital signs at each visit and their changes from baseline will be 
summarized for each treatment group. 
Exploratory
Will be specified in the statistical analysis plan. 
10.3.3.
Other analyses
Other analyses will be specified in the statistical analysis plan.
10.3.4.
Interim analyses
The details of the interim analysis plan will be specified in the statistical analysis plan.
When all subjects (except for early termination) complete the visit at Week 24 of the initial dose, 
the data on all of the subjects until Week 24 of the initial dose may be locked, unblinded, and analyzed 
for reporting to authorities.

Appendix 2: Clinical Laboratory Tests

The tests detailed in Table 10 will be performed by central laboratory. 

A test needs to be performed by study sites only if the result cannot be obtained from the 
central laboratory in time for study treatment and/or assessment. Even if measurement is 
performed at a study site, another sample at the same assessment timepoint is separately 
required for measurement at central laboratory. If a result of measurement at the study site 
is to be used for a decision of study treatment and/or assessment, the result should be 
recorded in the CRF. 

Protocol-specific inclusion/exclusion criteria are as specified in section 6 of the protocol.

necessary after the occurrence of hepatic events are specified in section 8.1 and Appendix 6. SAEs must 
be reported for all events with ALT IJYO3 times the upper limit of normal range (ULN), and at the same 
time, bilirubin IJYO2 times the ULN (direct bilirubin >35%), or ALT IJYO3 times the ULN, and at the 
same time, the international normalized ratio (INR) >1.5 if measured [which suggests a possibility of 
severe liver injury (applicable to Hy's Law)]. 
2. Pregnancy tests should be performed with serum samples at screening, and with urine samples for 
routine tests after randomization.

APPENDIX 4: Adverse Events: Definitions and Procedures for Recording, 
Evaluating, Follow-up, and Reporting
Definition of AE
AE Definition

An AE is any untoward medical occurrence in a clinical study participant, temporally 
associated with the use of a study treatment, whether or not considered related to the study 
treatment.

NOTE: An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of a study treatment.
Events Meeting the AE Definition

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or other
safety assessments (eg, ECG, radiological scans, vital signs measurements), including those 
that worsen from baseline, considered clinically significant in the medical and scientific 
judgment of the investigator (ie, not related to progression of underlying disease).

Exacerbation of a chronic or intermittent pre-existing condition including either an increase in 
frequency and/or intensity of the condition.

New conditions detected or diagnosed after study treatment administration even though it may 
have been present before the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction.

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study treatment or 
a concomitant medication. Overdose per se will not be reported as an AE/SAE unless it is an 
intentional overdose taken with possible suicidal/self-harming intent. Such overdoses should 
be reported regardless of sequelae.

"Lack of efficacy" or "failure of expected pharmacological action" per se will not be reported 
as an AE or SAE. Such instances will be captured in the efficacy assessments. However, the 
signs, symptoms, and/or clinical sequelae resulting from lack of efficacy will be reported as 
AE or SAE if they fulfill the definition of an AE or SAE.

The signs, symptoms, and/or clinical sequelae resulting from lack of efficacy will be reported 
as AE or SAE if they fulfill the definition of an AE or SAE. Also, "lack of efficacy" or 
"failure of expected pharmacological action" constitutes an AE or SAE.


2017N315029_02
CONFIDENTIAL
207660
68
Events NOT Meeting the AE Definition

Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the participant’s condition.

The disease/disorder being studied or expected progression, signs, or symptoms of the 
disease/disorder being studied, unless more severe than expected for the participant’s 
condition.

Medical or surgical procedure (eg, endoscopy, appendectomy): the condition that leads to 
the procedure is the AE.

Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital).

Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or 
detected at the start of the study that do not worsen.
Definition of an SAE
If an event does not correspond any of the above definitions of an AE, even if it is a serious condition, 
it will not be regarded as an SAE (e.g.; hospitalization due to the signs/symptoms of the disease being 
studied, death caused by exacerbation of the disease).
A SAE is defined as any untoward medical occurrence that, at any dose:
a.
results in death
b.
is life-threatening
The term 'life-threatening' in the definition of 'serious' 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, which hypothetically might have 
caused death, if it were more severe.
c.
requires hospitalization or prolongation of existing hospitalization
In general, hospitalization signifies that the subject has been detained (usually involving at least an 
overnight stay) at the hospital or emergency ward for observation and/or treatment that would not 
have been appropriate in the investigator’s office or out-patient setting. Complications that occur 
during hospitalization are AEs. If a complication prolongs hospitalization or fulfils any other serious 
criteria, the event is serious. When in doubt as to whether “hospitalization” occurred or was necessary, 
the AE should be considered serious. Hospitalization for elective treatment of a pre-existing condition 
that did not worsen from baseline is not considered an AE.
d.
Results in persistent disability/incapacity

The term disability means a substantial disruption of a person’s ability to conduct normal 
life functions.

This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, and 
accidental trauma (e.g. sprained ankle) which may interfere or prevent everyday life 
functions but do not constitute a substantial disruption.
e.
is congenital anomaly/birth defect


2017N315029_02
CONFIDENTIAL
207660
69
f.
other important medical situations:

Medical or scientific judgement should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize the 
subject or may require medical or surgical intervention to prevent one of the other outcomes 
listed in the above definition. These should also be considered serious.
Examples of such events are invasive or malignant cancers, intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or convulsions that 
do not result in hospitalization, or development of drug dependency or drug abuse.
Cardiovascular Events (CV) Definition:
Investigators will be required to fill out the specific CV event page of the CRF for the following AEs 
and SAEs:

Myocardial infarction/angina unstable

Cardiac failure congestive

Arrhythmia

Valvular disease

Pulmonary hypertension

Cerebrovascular event/stroke and transient ischemic attack

Peripheral arterial thromboembolism

Deep vein thrombosis/pulmonary embolism

Revascularisation
Recording of AEs and SAEs
AE and SAE Recording

When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (eg, hospital progress notes, laboratory, and diagnostics reports) related to 
the event.

The investigator will then record all relevant AE/SAE information in the CRF.

It is not acceptable for the investigator to send photocopies of the participant’s medical 
records to GSK in lieu of completion of the GSK /AE/SAE CRF page.

There may be instances when copies of medical records for certain cases are requested by 
GSK. In this case, all participant identifiers, with the exception of the participant number, 
will be redacted on the copies of the medical records before submission to GSK.

The investigator will attempt to establish a diagnosis of the event based on signs, symptoms, 
and/or other clinical information. Whenever possible, the diagnosis (not the individual 
signs/symptoms) will be documented as the AE/SAE.


2017N315029_02
CONFIDENTIAL
207660
70
Assessment of intensity
The investigator will make an assessment of intensity for each AE and SAE reported during the study 
and classify it to one of the following categories:

Mild: An event that is easily tolerated by the subject, causing minimal discomfort and not 
interfering with everyday activities.

Moderate: An event that is sufficiently discomforting to interfere with normal everyday 
activities.

Severe: An event that prevents normal everyday activities - An AE that is assessed as severe 
will not be confused with an SAE. Severity is a category utilized for rating the intensity of 
an event; and both AEs and SAEs can be assessed as severe.
An event is defined as “serious”, not when it is assessed as severe but when it meets at least one of the 
pre-defined outcomes as described in the definition of an SAE.
Assessment of causality

The investigator is obligated to assess the relationship between investigational product and 
the occurrence of each AE/SAE.

A “reasonable possibility” is meant to convey that there are facts/evidence or arguments to 
suggest a causal relationship, rather than a relationship cannot be ruled out.

The investigator will use clinical judgement to determine the relationship.

Alternative causes, such as natural history of the underlying diseases, concomitant therapy, 
other risk factors, and the temporal relationship of the event to the investigational product 
will be considered and investigated.

The investigator will also consult the IB, for marketed products, in the determination of 
his/her assessment.

The investigator must record that he or she reviewed AEs and SAEs and assessed the 
causality in the medical record.

There may be situations when an SAE has occurred and the investigator has minimal 
information to include in the initial report to GSK. However, it is very important that the 
investigator always make an assessment of causality for every event prior to the initial 
transmission of the SAE data to GSK.

The investigator may change his/her opinion of causality in light of follow-up information, 
prepare and send the follow-up report of SAE by amending the assessment result of the 
causality accordingly.

The causality assessment is one of the criteria used when determining regulatory reporting 
requirements.


2017N315029_02
CONFIDENTIAL
207660
71
Follow-up of AEs and SAEs

The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by GSK to 
elucidate the nature and/or causality of the AE or SAE as fully as possible. This may 
include additional laboratory tests or investigations, histopathological examinations, or 
consultation with other health care professionals.

If a subject dies during participation in the study, the investigator will provide GSK with a
copy of any post-mortem findings, including histopathology.

New or updated information will be recorded in the originally completed CRF.

The investigator will submit all updated SAE data to GSK within 24 hours after obtaining 
the information.
Reporting of SAEs to GSK
SAE Reporting to GSK via Electronic Data Collection Tool

The primary mechanism for reporting SAE to GSK will be the electronic data collection 
tool.

If the electronic system is unavailable for more than 24 hours, then the site will use the 
paper SAE data collection tool (see next section).

The site will enter the SAE data into the electronic system as soon as it becomes available.

The investigator or medically-qualified sub-investigator must show evidence within the 
eCRF (e.g., check review box, signature, etc.) of review and verification of the relationship 
of each SAE to IP/study participation (causality) within 72 hours of SAE entry into the 
eCRF.

After the study is completed at a given site, the electronic data collection tool will be taken 
off-line to prevent the entry of new data or changes to existing data.

If a site receives a report of a new SAE from a study participant or receives updated data on 
a previously reported SAE after the electronic data collection tool has been taken off-line, 
then the site can report this information on a paper SAE form (see next section) or to the 
SAE coordinator by telephone.

Contacts for SAE reporting can be found in ATTACHMENT.
SAE Reporting to GSK via Paper CRF

Facsimile transmission of the SAE page of the CRF is the preferred method to transmit the 
information on SAEs to GSK. 

In rare circumstances and in the absence of facsimile equipment, initial notification by 
telephone is acceptable followed by a copy of the SAE page of the CRF sent by overnight 
mail or by courier. 

Initial notification via the telephone does not replace the need for the investigator (or 
subinvestigator) to complete and sign the SAE page of the CRF within the designated 
reporting time frames.

The ATTACHMENT 1 shows a contact information to which the SAEs should be reported.

APPENDIX 5: Contraceptive Guidance and Collection of Pregnancy 
Information
Definition
Woman of Childbearing Potential (WOCBP)
A woman is considered fertile following menarche and until becoming post-menopausal unless 
permanently sterile (see below)
Women in the following categories are not considered WOCBP
1.
Premenarchal
Premenopausal female with ONE of the following:

Documented hysterectomy

Documented bilateral salpingectomy

Documented bilateral oophorectomy
Note: Documentation can come from the site personnel’s: review of participant’s medical records, 
medical examination, or medical history interview.
Postmenopausal women

A postmenopausal state is defined as no menses for 12 months without an alternative
medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal 
range may be used to confirm a postmenopausal state in women not using hormonal 
contraception or hormonal replacement therapy (HRT). However, in the absence of 12 
months of amenorrhea, a single FSH measurement is insufficient.

Females on HRT and whose menopausal status is in doubt will be required to use one of the 
non-hormonal highly effective contraception methods if they wish to continue their HRT 
during the study. Otherwise, they must discontinue HRT to allow confirmation of 
postmenopausal status before study enrollment.
Contraception Guidance
Male study subject

A male study subject who has a female partner of childbearing potential can participate in 
this study if he agrees to any of the following conditions: 

He must agree not to have a sex (sexual intercourse) with a person of the opposite sex as a 
normal favourable lifestyle (continuously having no sex for a long period of time) and also 
agree to keep that condition. 

If he has a sex with a woman of childbearing potential, he must agree to use a male condom
and use at least one of the contraception methods with an annual failure rate below 1% 
which are shown in Table 11.

A male study subject who has a pregnant or breastfeeding female partner must agree not to 
have a sex from the time during the study or use a male condom when having a sex. 

A male study subject must agree not to provide his sperm during the study.

Female study subject
A female study subject of childbearing potential can participate in this study if she agrees to use any 
of the extremely effective methods of contraception shown in Table 11continuously and accurately. 
Among the methods of contraception shown in Table 11, those deleted with strikethrough lines have 
neither been approved nor been accepted in Japan.
Table 11    Extremely effective methods of contraception
User-dependent extremely effective methods of contraception a
Their annual failure rates are below 1% if they are used continuously and accurately.
Contraception by mixed (estrogen and progestogen-containing) hormone preparation (inhibit 
ovulation)b

Oral

Intravaginal

Transdermal
Contraception by only progestogen-containing hormone preparation (inhibit ovulation)b

Injection
User-independent extremely effective methods of contraception

Contraception by only progestogen-containing implantable hormone preparation (inhibit 
ovulation)b

Intrauterine device (IUD)

Intrauterine system (IUS)

Bilateral tubal occlusion
Male partner’s vasectomy
(If her male partner has been vasectomised, it is an extremely effective method of contraception for a 
woman of childbearing potential if that partner is the only man with whom she has a sex and it has 
been confirmed that he is sterile. Otherwise, he/she must use other additional extremely effective 
method(s) of contraception.)
Having no sexual relations
(If the subjects decide to refrain himself or herself from having a sex of the opposite sex for the entire 
period when there is a risk of the investigational product, abstinence is deemed to be an extremely 
effective method of contraception. However, the credibility of abstinence needs to be evaluated during 
the study period and from the perspectives of the subject’s normal favourable lifestyle.)
Notes:
a.
The usual failure rate is different from the rate when contraception is used continuously and 
accurately. The subjects should use the methods of contraception that match with regulations 
concerning the methods of contraception for study subjects in each country.
b.
The efficacy of contraception by hormone preparations may decrease as a result of the interaction 
with the investigational product. In that case, the subject should use two extremely effective 
methods of contraception during the treatment period and at least for 3 months after the last dose 
of the investigational product.

Pregnancy test

A woman of childbearing potential can be enrolled to this study only if it is confirmed that 
she is negative in a highly sensitive serum pregnancy test along with her menstrual period. 

Pregnancy test should be performed if no menstruation occurred or she is suspected to be 
pregnant.

Analysis should be performed according to the package insert using a testing kit provided 
by GSK.
Collection of pregnancy information
If a male study subject’s partner becomes pregnant

Investigator will attempt to collect pregnancy information on any male participant’s female 
partner of a male study participant who becomes pregnant while participating in this study. 
This applies only to participants who receive study treatment.

After obtaining the necessary signed informed consent from the pregnant female partner 
directly, the investigator will record pregnancy information on the appropriate form and 
submit it to GSK within 2 weeks of learning of the partner’s pregnancy.

Partner will also be followed to determine the outcome of the pregnancy. Information on the 
status of the mother and child will be forwarded to GSK

Generally, follow-up will be no longer than 6 to 8 weeks following the estimated delivery 
date. Any termination of the pregnancy will be reported regardless of fetal status (presence 
or absence of anomalies) or indication for procedure.
Female Participants who become pregnant

Investigator will collect pregnancy information on any female participant, who becomes 
pregnant while participating in this study. 

Information will be recorded on the appropriate form and submitted to GSK within 24 hours 
of learning of a participant's pregnancy. 

Participant will be followed to determine the outcome of the pregnancy. The investigator 
will collect follow up information on participant and neonate, which will be forwarded to 
GSK Generally, follow-up will not be required for longer than 6 to 8 weeks beyond the 
estimated delivery date.

Any termination of pregnancy will be reported, regardless of fetal status (presence or 
absence of anomalies) or indication for procedure.

While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication 
or elective termination of a pregnancy will be reported as an AE or SAE.

A spontaneous abortion is always considered to be an SAE and will be reported as such.

Any SAE occurring as a result of a post-study pregnancy which is considered reasonably 
related to the study treatment by the investigator, will be reported to GSK as described in 
Appendix 4. While the investigator is not obligated to actively seek this information in 
former study participants, he or she may learn of an SAE through spontaneous reporting.

Study Design
Overview of Study Design and Key Features
Design 
Features
This study includes a Screening Phase, Blind Phase, and Open-label Phase. The 
study design of each treatment phase is shown below.

Blind Phase: Multicenter, randomized, double-blind, placebo-controlled, 
parallel-group comparison design

Open-Label Phase: Multicenter, uncontrolled, open-label design
Dosing

In the Blind Phase, participants will be randomly assigned 1:1 to either the 400 or 
the 240-unit group.

In the 400-unit group, 240 units of the product will be injected into the 
muscles that act on the finger (including thumb flexors) and wrist flexors, and 
160 units into the muscles that act on the elbow flexors. A total of 400 units 
of the product will be injected. 

In the 240-unit group, 240 units of the product will be injected into the 
muscles that act on the finger (including thumb flexors) and wrist flexors. 
Placebo will be injected into the muscles that act on the elbow flexors. A total 
of 240 units of the product will be injected. 

In the Open-label phase, a total of 400 units will be injected in both groups. 

The product can be injected up to 3 times after completion of Part 1 in the 
blind phase. Participants whom the investigator considers as eligible for the 
injections will be treated. The next injections cannot be performed until the 
eligibility of the participant has been confirmed by the investigator. 

The muscle to be injected and the dose will be decided by the investigator 
based on the patient’s symptoms, and a total dose of 400 units of the product 
will be injected in a divided dose. For the muscles that the investigator 
considers as unnecessary to be treated, an injection may be skipped. The 
involving muscle and the dose do not have to be same each time always.

Statistical Methodology Specification
Endpoint / Variables

Responder Rate of MAS in the elbow flexors at Week 6 of the initial dose
Model Specification

To summarize the primary endpoint without statistical model
o
The primary endpoint will be calculated as the proportion of participants whose MAS score 
decreased by at least 1 level from the baseline in the ITT1 population.
o
The intergroup difference in the responder rate and its 95% confidence interval (Wald-
type) will be computed.
Data Convention

The MAS scores, 0, 1, 1+, 2, 3 and 4 will be encoded to 0, 1, 2, 3, 4 and 5, respectively, for the 
analyses.
Definition of Responder and Responder rate
“Responder” is defined as a participant whose MAS score decrease by at least 1 level from the 
baseline. 
Responder Rate will be calculated as below. 
Responder Rate (%) = (Number of Respondersparticipant) / (Number of participants in ITT1 
population) x 100

If MAS score of a given participant is missing at Week 6, then this participants will be regarded 
as a non-responder.
Model Results Presentation

6.2.3.
Population of Interest
The secondary efficacy analyses will be based on the Intent-To-Treat 1 population, unless 
otherwise specified.
The secondary efficacy analyses will be performed for only double blind phase. All 
efficacy analyses for open -label phase and other endpoints for double blind phase will be 
done as exploratory.
Unless specified otherwise, the data up to Week 12 of treatment will be summarized 
during the double-blind period. This is because this study allows to re-treat. In other 
words, after 12 weeks, only participants who have a smaller MAS score would remain 
and the difference of the change from baseline in MAS between 240 units and 400 units 
would be attenuated. Therefore, the data up to Week 12 of initial treatment will be 
analysed as secondary statistical analyses. This is the case for exploratory analyses for 
open label period (i.e. the data up to week 12 of re-treatment will be summarized). 
Listing will include the data after week 12 of treatment/re-treatment.
6.2.4.
Strategy for Intercurrent (Post-Randomization) Events
Intercurrent event: early withdrawal from study.
Strategy for dichotomous data: the participant will be regarded as a non-responder.
Strategy for continuous data: the missing data will be removed from the analyses.

a.
Test items for screening must be performed from 4 weeks to 1 weeks before Day 1 visit (±3 days).
b.
Eligibility evaluation (Qualification for Retreatment Visit: QRV) will be performed at V5 as a starting point if a participant does not meet the criteria only. 
The evaluation is performed at a 4-week interval, V5 as a starting point, The QRV when a participant meets the criteria will be a same day as the injection in 
the next treatment period.
c.
If a participant is evaluated to meet the eligibility for the injection in the blind phase at V5, the participant will move forward to Part 2 in the open-label 
phase (Namely, V5 in Part 1 and V1 in Part 2 is a same day). If the participant does not meet the eligibility, QRV will be performed 4 weeks later, at V5 as s 
starting point. 
d.
If a participant is evaluated to meet the eligibility at V5 in the open-label phase, the participant will move forward to the next treatment phase (V5 and V1 in 
the next treatment phase is a same day). If the participant does not meet the eligibility, QRV is performed 4 weeks later, V5 as a starting point. If V5 in each 
treatment phase is at Week 48 after initial injection, V5 will be considered to be completion visit (FV). However, for the testing items, pre-scheduled tests at 
V5 and neutralizing antibody tests will be performed. If V5 in Parts 2 and 3 is performed at Week 36 or later, after completion of V5, completion visit will 
be performed at Week 48.
e.
QRV is allowable to perform from initial injection to Week 36. Eligibility evaluation (QRV) will not be performed after Week 36.  
f.
V5 must be performed at least 84 days after V1. 
g.
The acceptable visit windows will be -14 to +4 days if QRV is performed at Week 36.
h.
Must be performed earlier than any other procedures
i.
Must be performed before injection of the product
j.
For inclusion/exclusion criteria, the items to be observed are different between screening phase and Day 1. For details, refer to Protocol Section 6.1 and 
Section 6.2.

k.
For MAS evaluation, the items to be evaluated differ depending on the treatment phase. For details, refer to Protocol Section 9.1.1.1.
l.
MAS evaluation will be followed by NRS evaluation. For NRS evaluation, items to be evaluated differ. For details, refer to Protocol Section 9.1.1.2.
m. Body temperature, heart rate, and blood pressure will be measured as vital signs. 
n.
Women of childbearing potential will be only performed. Serum hCG pregnancy test must be performed at screening, and urine hCG pregnancy test after 
randomization. The tests can be performed beyond the protocol specifications if an investigator considers to be necessary.  
o.
For laboratory test items, refer to Protocol Section 12.2. Attachment 2. Fasting is not required for blood collection. 
p.
Adverse events and serious adverse events collection period will be from the initial injection day (Day 1) to completion visit (FV).
q.
Neutralizing antibody testing is performed 3 times in each participant. The first test will be performed in screening phase, the second is at V5 in the blind 
phase, and the third is at completion visit.
r.
A participant who withdraws the study before 12 weeks after last injection will be performed. 
s.
Perform if V5 in each treatment phase is at Week 48 after initial injection
t.
Not necessary to perform doubly as V1 assessment if the same assessment is performed at V5 or QRV. If V1 assessment or retreatment cannot be performed 
on the same day as V5 or QRV, MAS assessment should be performed again on the day of visit for the V1 assessment.
u.
Evaluation of retreatment is performed only when the dosing conditions (1 to 5) of retreatment evaluation are met. If V1 assessment or retreatment cannot be 
performed on the same day as V5 or QRV, body weight, pulmonary function test, electrocardiogram, and pregnancy test should not be performed again on 
the day of visit for V1 assessment.
v.
V1 assessment in Part 2 or subsequent parts should be performed as a rule on the same day as V5 or QRS (when eligibility was confirmed) of the previous 
part. If this is not possible, the V1 assessment may be performed on another day but within the acceptable visit window.

SUMMARY OF KEY PROTOCOL INFORMATION
2.1.
Changes to the Protocol Defined Statistical Analysis Plan
There was one change to the originally planned statistical analysis specified in the 
protocol amendment 02 [(Dated: 06OCT2017)] as the following Table shows: 
Protocol
Reporting & Analysis Plan
Objectives and endpoints
Statistical Analysis Plan
Rationale for Changes

Exploratory endpoints

Changes in MAS score from 
baseline in finger, thumb, 
wrist, elbow, pronation of the 
forearm and shoulder flexors

Change from baseline in MAS 
scores of the finger, thumb, 
wrist and elbow only will be 
calculated, whereas those of 
the pronation of the forearm 
and shoulder will not. 

MAS scores in the pronation 
of the forearm and shoulder 
flexors were not collected in 
Blind Phase. 

Since baseline value is 
defined as the latest value 
prior to the initial treatment, 
the baseline value would be 
usually the data at Visit1 in 
Blind Phase.  

Therefore, there were not the 
data of the baseline value in 
the pronation of the forearm 
and shoulder
flexors, and 
changes from baseline 
cannot be calculated.

and 160 units into the muscles that act on the elbow flexors. A total of 400 
units of the product will be injected. 

In the 240-unit group, 240 units of the product will be injected into the 
muscles that act on the finger (including thumb flexors) and wrist flexors. 
Placebo will be injected into the muscles that act on the elbow flexors. A 
total of 240 units of the product will be injected. 

In the Open-label phase, a total of 400 units will be injected in both groups. 

The product can be injected up to 3 times after completion of Part 1 in the 
blind phase. Participants whom the investigator considers as eligible for 
the injections will be treated. The next injections cannot be performed until 
the eligibility of the participant has been confirmed by the investigator. 

The muscle to be injected and the dose will be decided by the investigator 
based on the patient’s symptoms, and a total dose of 400 units of the 
product will be injected in a divided dose. For the muscles that the 
investigator considers as unnecessary to be treated, an injection may be 
skipped. The involving muscle and the dose do not have to be same each 
time always.

The primary endpoint will be calculated as the proportion of participants whose MAS score 
decreased by at least 1 level from the baseline in the ITT1 population.
o
The intergroup difference in the responder rate and its 95% confidence interval (Wald-
type) will be computed.
Data Convention

The MAS scores, 0, 1, 1+, 2, 3 and 4 will be encoded to 0, 1, 2, 3, 4 and 5, respectively, for the 
analyses.
Definition of Responder and Responder rate
“Responder” is defined as a participant whose MAS score decrease by at least 1 level from the 
baseline. 
Responder Rate will be calculated as below.

Unless specified otherwise, the data up to Week 12 of treatment will be summarized 
during the double-blind period. This is because this study allows to re-treat. In other 
words, after 12 weeks, only participants who have a smaller MAS score would remain 
and the difference of the change from baseline in MAS between 240 units and 400 units 
would be attenuated. Therefore, the data up to Week 12 of initial treatment will be 
analysed as secondary statistical analyses. This is the case for exploratory analyses for 
open label period (i.e. the data up to week 12 of re-treatment will be summarized). 
Listing will include the data after week 12 of treatment/re-treatment.
7.2.4.
Strategy for Intercurrent (Post-Randomization) Events

data will be summarized using the descriptive statistics below and listed. 

The number of events and censored cases. 

Median survival time with the associated 95% CI. 

25% and 75% survival time. 
Survival analyses will be conducted using a Kaplan-Meier method. To graphically 
compare the survival functions between 400 units and 240 units, the analysis will be 
conducted based on ITT 1 population whereas the analyses will be based on ITT 2 and 3
populations to assess the survival time by treatment cycle. Participants who are 
withdrawn from this study before the events are censored at the withdrawal date. All 
other participants who do not experience the event and is not withdrawn from study are 
censored at the Last Observed Visit at the interim analyses or the final analyses.
Survival function estimates will be summarized (survival probabilities and the number of 
participants at risk per time to event, and median in survival time) based on Kaplan Meier 
method. Kaplan Meier plots will be presented. 
Note that the retreatment is not allowed within 83 days from the previous treatment. 
Therefore, this event will not occur before 83 days later after the treatment/re-treatment.

planned displays are provided in Appendix 12: List of Data Displays.
Adverse events that occurred in the overall study period, blinded period and open-label 
period will be summarized for each treatment group. The treatment group is based on 
dose actually given in blind period. For the blinded period, 2 patterns of analyses on 
adverse events will be performed, one is on adverse events that occurred between the 
initial dose and the first dose in the open-label period (or at the completion of study if no 
dose is given in the open-label period or at the study withdrawal), and another one is on 
adverse events that occurred within 84 days from the initial dose.

are: No Change/Decreased, Any Increase, Increase to TRA, Increase to 1+, Increase to 
2+, Increase to 3+, Increase to 4+. The categorization is determined by comparing the 
baseline category to the worst case post-baseline category.  The determination of the 
worst case post-baseline takes into account both planned and unscheduled assessments.  
The percentages are based on the number of subjects in the treatment group with data for 
the test post-baseline. Subjects with missing baseline value are to be assumed to have 
normal/within range baseline value.
Shifts from baseline relative to normal range will be summarized by treatment group and 
visit for Chemistry and Hematology values.

a.
Test items for screening must be performed from 4 weeks to 1 weeks before Day 1 visit (±3 days).
b.
Eligibility evaluation (Qualification for Retreatment Visit: QRV) will be performed at V5 as a starting point if a participant does not meet the criteria only. 
The evaluation is performed at a 4-week interval, V5 as a starting point, The QRV when a participant meets the criteria will be a same day as the injection in 
the next treatment period.
c.
If a participant is evaluated to meet the eligibility for the injection in the blind phase at V5, the participant will move forward to Part 2 in the open-label 
phase (Namely, V5 in Part 1 and V1 in Part 2 is a same day). If the participant does not meet the eligibility, QRV will be performed 4 weeks later, at V5 as s 
starting point. 
d.
If a participant is evaluated to meet the eligibility at V5 in the open-label phase, the participant will move forward to the next treatment phase (V5 and V1 in 
the next treatment phase is a same day). If the participant does not meet the eligibility, QRV is performed 4 weeks later, V5 as a starting point. If V5 in each 
treatment phase is at Week 48 after initial injection, V5 will be considered to be completion visit (FV). However, for the testing items, pre-scheduled tests at

V5 and neutralizing antibody tests will be performed. If V5 in Parts 2 and 3 is performed at Week 36 or later, after completion of V5, completion visit will 
be performed at Week 48.
e.
QRV is allowable to perform from initial injection to Week 36. Eligibility evaluation (QRV) will not be performed after Week 36.  
f.
V5 must be performed at least 84 days after V1. 
g.
The acceptable visit windows will be -14 to +4 days if QRV is performed at Week 36.
h.
Must be performed earlier than any other procedures
i.
Must be performed before injection of the product
j.
For inclusion/exclusion criteria, the items to be observed are different between screening phase and Day 1. For details, refer to Protocol Section 6.1 and 
Section 6.2.
k.
For MAS evaluation, the items to be evaluated differ depending on the treatment phase. For details, refer to Protocol Section 9.1.1.1.
l.
MAS evaluation will be followed by NRS evaluation. For NRS evaluation, items to be evaluated differ. For details, refer to Protocol Section 9.1.1.2.
m. Body temperature, heart rate, and blood pressure will be measured as vital signs. 
n.
Women of childbearing potential will be only performed. Serum hCG pregnancy test must be performed at screening, and urine hCG pregnancy test after 
randomization. The tests can be performed beyond the protocol specifications if an investigator considers to be necessary.  
o.
For laboratory test items, refer to Protocol Section 12.2. Attachment 2. Fasting is not required for blood collection. 
p.
Adverse events and serious adverse events collection period will be from the initial injection day (Day 1) to completion visit (FV).
q.
Neutralizing antibody testing is performed 3 times in each participant. The first test will be performed in screening phase, the second is at V5 in the blind 
phase, and the third is at completion visit.
r.
A participant who withdraws the study before 12 weeks after last injection will be performed. 
s.
Perform if V5 in each treatment phase is at Week 48 after initial injection
t.
Not necessary to perform doubly as V1 assessment if the same assessment is performed at V5 or QRV. If V1 assessment or retreatment cannot be performed 
on the same day as V5 or QRV, MAS assessment should be performed again on the day of visit for the V1 assessment.
u.
Evaluation of retreatment is performed only when the dosing conditions (1 to 5) of retreatment evaluation are met. If V1 assessment or retreatment cannot be 
performed on the same day as V5 or QRV, body weight, pulmonary function test, electrocardiogram, and pregnancy test should not be performed again on 
the day of visit for V1 assessment.
v.
V1 assessment in Part 2 or subsequent parts should be performed as a rule on the same day as V5 or QRS (when eligibility was confirmed) of the previous 
part. If this is not possible, the V1 assessment may be performed on another day but within the acceptable visit window.

Definitions of Assessment Windows for Efficacy Analyses (only 
Final Visit and Withdraw Visit, and only Final Analyses)
If the Visit 5 in last treatment cycle coincides with Final Visit (e.g., Visit 5 in 3rd 
treatment cycle is achieved on Week 48 from the initial dose), the efficacy data will be 
entered as Final Visit, not the last visit in the treatment cycle. However, actually the data 
at the last visit is not missing. Therefore, in the following cases, the Final Visit data will 
be treated as the Visit 5 in the last treatment cycle for the efficacy analyses. 
Where the participant (except for the withdrawn from study) who was qualified for re-
treatment:

At Week 12 in Blind Phase, 2nd and 3rd Open Label Phase

At Week 12 in Blind Phase and at Week 24 in 2nd Open Label Phase. 

At Week 16 in Blind Phase and at Week 20 in 2nd Open Label Phase.


General
Study Day

Calculated as the number of days from First Dose Date:

Ref Date = Missing              → Study Day = Missing 

Ref Date < First Dose Date → Study Day = Ref Date – First Dose Date

Ref Data ≥ First Dose Date → Study Day = Ref Date – (First Dose Date) + 1    
10.6.2.
Study Population
Age

GSK standard IDSL algorithms will be used for calculating age where birth date will be imputed as 
follow:
o
Any participant with a missing date and month will have this imputed as ‘30th June’.

Birth date will be presented in listings as ‘YYYY’. 

Age will be calculated based on year of the Screening visit as an Age reference date.

Extent of Exposure

The total of dosage per treatment cycle will be calculated based on the formula:
Total of Dosage per treatment cycle = Sum of (Dosage in each Muscle Region)

The subtotal of dosage in each joint per treatment cycle will be calculated based on the formula:
Subtotal of Dosage in the joint per treatment cycle = Sum of (Dosage in each Muscle Region of 
the Joint)

Example
Subtotal of Dosage in Elbow = Sum of (Dosage in Biceps brachii, Brachalis and Brachioradialis)

Reporting Detail
General

Participant study completion (i.e. as specified in the protocol) was defined as those who 
completed all the study procedures, including a completion visit. . 

Withdrawn participants were not replaced in the study.

All available data from participants who were withdrawn from the study will be listed 
and all available planned data will be included in summary tables and figures, unless 
otherwise specified.

Withdrawal visits will be slotted as per Appendix 3: Assessment Windows or will be 
summarised as withdrawal visits.
10.7.2.
Handling of Missing Data
Element
Reporting Detail
General

Missing data occurs when any requested data is not provided, leading to blank fields on 
the collection instrument:
o
These data will be indicated by the use of a “blank” in participant listing displays. 
Unless all data for a specific visit are missing in which case the data is excluded 
from the table. 
o
Answers such as “Not applicable” and “Not evaluable” are not considered to be 
missing data and should be displayed as such.
Responder 
of MAS

If MAS score is missing at the corresponding visit, the participant will be regarded as 
those who are a non-responder (i.e. non-responder imputation).
