PROTOCOL SUMMARY 
Background and Rationale
Topical diclofenac products are well established globally for the treatment of pain and inflammation 
due to acute trauma as well as for the relief of pain associated with non-serious osteoarthritis (OA) 
of the peripheral joints e.g. knee and fingers. The originator product diclofenac diethylamine 
(DDEA) 1.16% gel (Voltarol Emulgel in the UK, and generic name of DDEA Emulgel was 
registered in China) was first registered in 1985 in Switzerland and Romania for use at a dose of 
2-4 g applied three to four times daily and is currently registered in over 130 countries of which 
over 80 countries market this product as over-the-counter (OTC).
As part of the global expansion for the product, China has been identified as a desirable market for 
registration of DDEA 2.32% gel. The identified registration pathway in China for the DDEA 2.32% 
gel is variation specifying addition of a new strength to the already registered DDEA 1.16% gel 
(License Number H20181225/H20181226, firstly issued on March 12, 2013), with the same 
indications as currently registered for DDEA 1.16% gel, i.e. for the relief of mild to moderate pain 
in muscles, soft tissues, and joints, e.g. muscles or soft tissue pains caused by sprain, pulling injury, 
contusions, strain, waist-back injury and various arthralgia etc, and for symptomatic treatment of 
osteoarthritis.
In support of the proposed registration, the National Medical Products Administration (NMPA) 
approved a clinical trial application (CTA) on November 06, 2016 (CTA No. 2016L09875). The 
approved CTA stipulated that a non-inferiority study assessing the efficacy and safety of the DDEA 
2.32% versus that of the registered DDEA 1.16% should be conducted in a local population.
To this effect, GSKCH intends to conduct a randomized, double blind, multi-center, active 
controlled, parallel group, non-inferiority study to evaluate the efficacy and safety of DDEA 2.32% 
gel applied twice daily versus DDEA 1.16% gel applied four times daily in subjects with ankle 
sprain in China.
Objectives and Endpoints
Objective(s)
Endpoint(s)
Primary
To demonstrate non-inferiority between DDEA 
2.32% and DDEA 1.16% with regard to pain 
relief after acute ankle sprain
Change from baseline in pain on movement 
(POM) on Day 5 of treatment as assessed by a 
100 mm VAS scale
Secondary
To assess safety of DDEA 1.16% and DDEA 
2.32% gels after 1 week of use
Number, incidence, and severity of adverse 
events following dosing with study medication
To assess efficacy of treatments for pain relief 
as measured by POM on Days 3 and 8
Change from baseline of POM on VAS on Day 3 
and Day 8 of treatment assessed by 100 mm 
VAS scale
To assess efficacy of treatments for 
inflammation of the affected ankle as measured 
by pressure algometry on Days 3, 5, and 8
Change from baseline in tenderness as 
measured by pressure algometry on Days 3,5, 
and 8
To assess efficacy of treatments for 
inflammation of the affected ankle as measured 
by pressure algometry on Days 3, 5, and 8
Difference between measurement in affected 
ankle and contralateral ankle on Days 3,5,and 8
To assess efficacy of treatments for ankle joint 
function as measured on the Karlsson Scoring 
Scale
Change from baseline in Ankle Joint Function 
(Karlsson Scoring Scale) on Days 3,5, and 8

Study Design
This is a Phase III, randomized, double blind, multi-center, active controlled, 2 treatment arm, 
parallel group, non-inferiority study to evaluate the efficacy and safety of diclofenac 
diethylamine 2.32% gel applied twice daily versus diclofenac diethylamine 1.16% gel applied 
four times daily for 1 week in subjects with acute ankle sprain.
To qualify, subjects must experience an acute Grade I -II sprain of the ankle within the past 24 
hours. Subjects should be randomized as soon as possible after the injury.
Subjects who meet all of the inclusion criteria and none of the exclusion criteria will be 
randomized in a 1:1 ratio to one of the following two treatment arms:

Approximately 300 subjects (150 in each group) with acute ankle sprain are to be randomized. 
All subjects will receive four (4) tubes of study drug, for treatment in morning, noon, late 
afternoon, and late evening, respectively. The very first dose of study drug will be applied at 
the study center. The subjects will be instructed to apply the gel topically with the finger tips 
(for approximately 1 minute) in the morning, at noon, late afternoon, and late evening for 7 
days. Each tube will be labeled for use at one of these 4 times.
After the randomization visit (Visit 1/baseline visit), subjects will return to the study site for 
post baseline visits, namely Visit 2, Visit 3, and Visit 4 to complete efficacy and safety 
assessments. Baseline safety laboratory test blood samples will be taken. End of study safety 
laboratory tests will also be taken at Visit 4, or in case of early termination. In addition, subjects 
(ex-clinic) will assess pain intensity and pain relief at frequent intervals on Day 1 and then at

Protocol Amendment 1
GlaxoSmithKline Consumer Healthcare Confidential 
Template Version Effective: 18-May-18 (CCR #11475)
Page 12 of 64
Type and Planned Number of Subjects
Approximately 300 subjects who present to the study within 24 hours of suffering a Grade I-II 
ankle sprain will be randomized to ensure at least 240 evaluable subjects complete the study for 
the (PP) per protocol analysis population. 
Approximately 120 subjects per treatment arm has been determined to provide 80% power to 
demonstrate non-inferiority of DDEA 2.32% gel b.i.d with DDEA 1.16% gel q.i.d. by 
comparing the two-sided 95% confidence interval (CI) of the difference in mean change from 
baseline of VAS POM score between the two products with the non-inferiority margin of 13 
mm.  This assumes a treatment standard deviation of 22mm and allows for a possible small true 
treatment difference of 5mm in favor of DDEA 1.16%.
The primary efficacy endpoint will be the change from baseline in POM on Day 5 of treatment 
as assessed by a 100 mm VAS scale.
The following primary non-inferiority hypothesis will be tested for DDEA 2.32% vs DDEA 
1.16%:
The null hypothesis is Diclofenac 2.32% DDEA Gel administered BID is inferior to Diclofenac 
1.16% DDEA gel administered QID with the alternative hypothesis being Diclofenac 2.32% 
DDEA Gel administered BID is non-inferior to Diclofenac 1.16% DDEA gel administered QID.
Diclofenac 2.32% DDEA Gel administered BID will be declared non-inferior to Diclofenac 
1.16% DDEA gel administered QID if the upper limit of the two-sided 95% CI of the difference 
between their mean changes from baseline VAS POM responses is less than the established 
margin of 13 mm.

STUDY DESIGN 
4.1
Overall Design
This is a Phase III, randomized, double blind, multi-center, active controlled, 2-treatment arm, 
parallel group, non-inferiority study to evaluate the efficacy and safety of diclofenac 
diethylamine 2.32% gel applied twice daily versus diclofenac diethylamine 1.16% gel applied 
four times daily for 1 week in subjects with acute ankle sprain.
To qualify, subjects must experience an acute Grade I -II sprain of the ankle within the past 24 
hours and experience pain on movement of at least 50 mm on a 100 mm VAS scale. Subjects 
should be randomized as soon as possible after the injury.
Subjects who meet all of the inclusion criteria and none of the exclusion criteria will be 
randomized in a 1:1 ratio to one of the following two treatment arms:

the study center. The subjects will be instructed to apply the gel topically with the finger tips 
for approximately 1 minute in the morning, at noon, late afternoon, and late evening for 7 days. 
Each tube will be labeled for use at one of these 4 times.
After the randomization visit (Visit 1/baseline visit), subjects will return to the study site for 
post baseline visits, namely Visit 2, Visit 3, and Visit 4 to complete efficacy and safety 
assessments. Baseline safety laboratory test blood samples will be taken at Visit 1. End of study 
safety laboratory tests will also be taken at Visit 4, or in case of early termination. In addition, 
subjects (ex clinic) will assess pain intensity and pain relief at frequent intervals on Day 1 and 
then at each study drug application throughout the rest of the study. The schedule of visits is 
described below.
Study center visits per subject:
Screening / Randomization visit [Visit 1]
Day 1 (0 h)
1st interim visit [Visit 2]
Day 3 (48 ± 4 h after initiating treatment)
2nd interim visit [Visit 3]
Day 5 (primary endpoint measurement) 
(96 ± 4 h after initiating treatment)
Final visit [Visit 4]
Day 8 ± 1 d
(7 ± 1 days after initiating treatment)
Rescue medication (paracetamol, up to 2000 mg daily) will be allowed during the study, except 
for the 6 hours prior to each study visit and 12 hours prior to Visit 3.
4.2
Rationale for Study Design
As discussed in Section 2.2 and Section 2.3, DDEA 1.16% and DDEA 2.32% are registered 
globally for the relief of pain, swelling and inflammation from a variety of musculoskeletal 
conditions. There is an extensive body of clinical study and post marketing experience to 
support the efficacy of both the DDEA 1.16% and 2.32%. Part of the rationale for conducting 
this study is to reproduce the efficacy and safety of the products in a Chinese population.
The DDEA 1.16% gel is currently marketed in China. As described in Section 2.1, in order to 
expand the global footprint of the DDEA 2.32% gel to China, a local study is required. The 
design stipulated in the NMPA approved CTA is a non-inferiority study design versus the 
approved DDEA 1.16% active comparator. This is considered an appropriate design when there 
is extensive evidence of efficacy and safety of the active comparator and the aim is to leverage 
this existing evidence by demonstrating that a new product which can offer advantages, such as 
improved compliance and convenience, would result in no important loss of efficacy versus the 
active comparator. The DDEA 1.16% has demonstrated consistent and reproducible efficacy as 
compared to placebo in both acute and chronic clinical pain models. Moreover, this is especially 
applicable to the current situation as the test product, DDEA 2.32%, has also demonstrated 
efficacy in a placebo-controlled trial. 
Given the extensive global evidence of safety and efficacy in both the active comparator and 
test arms, the important contribution resulting from the conduct of the non-inferiority trial is to 
demonstrate no important loss of efficacy from the approved active comparator in a local 
population.

4.3
Justification for Dose
The dose for the active comparator DDEA 1.16% will be an application of 5 cm of gel 
(equivalent to approximately 2 g of gel and as determined by a provided dosing card) to both 
sides of the affected ankle four (4) times daily. This is consistent with the approved labeled 
dose for DDEA 1.16% in China.
Globally, the labeled approved dose for DDEA 2.32% is an amount of 2 – 4 g of gel (roughly 
the size of a cherry or walnut) applied twice daily. To produce a more uniform dose for the 
purpose of the trial and to provide recommendations more in line with the approved labeled 
dose of the DDEA 1.16% in China, the dose for the trial for the DDEA 2.32% will be an 
application of 5 cm of gel (equivalent to 2 g of gel and as determined by a provided dosing card) 
to both sides of the affected ankle two (2) times daily. For subjects receiving DDEA 2.32% gel, 
placebo gel will be administered in the same fashion two (2) times daily to maintain blinding.
Based on previous experience it is expected that measurement of pain and disability over 
approximately one week would adequately characterize the profile over time of the analgesic 
effect of both DDEA 1.16% and DDEA 2.32% (Mason, et al 2004, Predel, et al 2004).
To minimize unnecessary risks to subjects during study participation subjects will be screened 
at baseline to ensure absence of the various clinical disorders described in the exclusion criteria. 
This comprehensive process consists of a baseline physical examination, vital signs, medical 
history and drug history. Safety laboratory blood samples for chemistry and hematology will  
also be taken at the baseline visit before subjects are randomized to study treatment, and their 
results will be reviewed as early as possible. 
4.4
End of Study Definition 
A subject is considered to have completed the study if he or she has completed all phases of the 
study including the last visit or the last scheduled procedure shown in the Schedule of Activities.
The end of this study is defined as the date of the last visit or the last scheduled procedure of 
the last subject in the study.

STUDY POPULATION
5.1
Type and Planned Number of Subjects
A sufficient number of subjects will be screened to randomize approximately 300 subjects to 
ensure at least 240 evaluable subjects complete the study without any major protocol deviations. 
Healthy adults 18 – 75 years old who present to clinic within 24 hours of sustaining a grade I 
or II lateral ankle sprain (as assessed by the investigator) and experience pain on movement of 
at least 50 mm on a 100 mm VAS scale will be enrolled into the study.
This study can fulfill its objectives only if appropriate subjects are enrolled. The following 
eligibility criteria are designed to select subjects for whom participation in the study is 
considered appropriate.  All relevant medical and non-medical conditions should be taken into 
consideration when deciding whether a subject is suitable for this protocol.  
Subject eligibility to participate in the clinical study should be reviewed by the investigator and 
documented by an appropriate member of the investigator’s study team before subjects are 
included in the study.

Contraception
Female subjects who are of childbearing potential and are sexually active and at risk for 
pregnancy must agree to use at least one highly effective method of contraception consistently 
and correctly for the duration of the active study period and for at least 14 days after the last 
dose of investigational product. 
The investigator or his or her designee will discuss with the subject the need to use highly 
effective contraception consistently and correctly according to the schedule of activities and 
document such conversation.  In addition, the investigator or designee will instruct the subject 
to call immediately if the selected contraception method is discontinued or if pregnancy is 
known or suspected in the subject or the subject’s partner. 
The following is the all-inclusive list of the highly effective methods for avoiding pregnancy 
that meets the GSK definition (i.e., have a failure rate of less than 1% per year when used 
consistently and correctly and, when applicable, in accordance with the product label). 
The list does not apply to females of reproductive potential with same sex partners or for 
subjects who are and will continue to be abstinent from penile-vaginal intercourse on a long 
term and persistent basis, when this is their preferred and usual lifestyle. Periodic abstinence 
(e.g. calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not 
acceptable methods of contraception.
1. Contraceptive subdermal implant
2. Intrauterine device or intrauterine system
3. Combined estrogen and progestogen oral contraceptive [Hatcher 2007])
4. Injectable progestogen [Hatcher 2007]

These allowed methods of contraception are only effective when used consistently, correctly 
and in accordance with the product label. The investigator is responsible for ensuring that 
subjects understand how to properly use these methods of contraception. Use of hormonal 
contraception will be allowed during the study; however, subjects must have been stabilized on 
this medication for at least 3 months prior to screening.
5.6
Screen Failures
Screen failures are defined as subjects who consent to participate in the clinical study but are 
not subsequently randomized. To ensure transparent reporting of screen failure subjects, a 
minimal set of screen failure information will include demography, screen failure details (e.g. 
withdrawal of consent), eligibility criteria, and any adverse events or incidents as applicable. 
Individuals who do not meet the criteria for participation in this study (screen failure) may not 
be re-screened.
5.7
Sponsor’s Qualified Medical Personnel
Contact information for the sponsor's appropriately qualified medical personnel for the study is 
documented in the Study Contact List located in the investigator study master file held at the 
study site.
The contact number is only to be used by investigational staff seeking advice on medical 
questions or problems in the event that the established communication pathways between the 
investigational site and the study team are not available.  
The contact number is not intended for direct use by study subjects. To facilitate access to 
appropriately qualified medical/dental personnel on study-related medical/dental questions or 
problems, subjects will be provided with a contact card.  The contact card will provide, as a 
minimum, protocol identifiers, the subject’s study identification number, contact information 
for the investigational site, and contact details in the event that the investigational site cannot 
be reached to provide advice on a medical question or problem identified by a healthcare 
professional other than the investigator.

Care should be taken with the supplied products and their labels so that they are maintained in 
good condition.  It is important that all labels remain intact and legible for the duration of the 
study. Subjects should be instructed to not remove or deface any part of the study label.
All products supplied are for use only in this clinical study and should not be used for any other 
purpose. Subjects must not exchange their designated products with other study subjects.
6.1.2
Preparation and Dispensing 
DDEA 2.32% gel, DDEA 1.16% gel, and placebo will be prepared and/or dispensed by 
qualified site personnel according to the dosage and administration instruction. 
Once the eligibility of a subject has been confirmed, the Investigator (or nominated assistant) 
should contact the IVRS/IWRS Centralized Randomization Centre for allocation of randomized 
therapy.
The actual treatment given to individual subjects will be determined by a randomization scheme 
that has been loaded into the (IVRS/IWRS) database. Subjects will be assigned to products in 
accordance with the randomization schedule generated by an approved GSK CH vendor, using 
validated software.
All subjects will be identified to the Centralized Randomization Centre using an Interactive 
Response Technology (IRT). Before the study is initiated, training, login information and 
directions for the IRT will be provided to each site. 
The IVRS/IWRS Centralized Randomization Centre will inform the investigator of the Kit ID 
number to be allocated to the subject after subjects become eligible for randomization.
6.2
Administration
All subjects will be given 4 tubes of study drug and the same usage instructions. Subjects should 
spread a total of approximately 2 grams of study medication (using the dosing card) on both 
sides of the ankle. The study drug should be applied topically with the fingertips to both sides 
of the affected ankle for approximately 1 minute (corresponds to a region of approximately 200 
cm2). After application, the hands should be washed. On Day 1, to demonstrate proper 
application, the first dose of study drug will be applied at the study center from the morning 
tube (regardless of the time of randomization). Subsequent doses will be applied from the tube 
associated with the corresponding time of day separated by at least 3 hours (i.e. if the first dose 
is applied at 15:00 hr from the morning tube, the next dose will be at approximately 18:00 hr 
from the late afternoon tube and the next dose will be at approximately 21:00 hr from the late 
evening tube).   All 4 doses of study drug should be applied on Day 1, if possible, preferably 
with at least 3 hours between doses. If this is not possible, at a minimum 3 doses should be 
administered with at least 3 hours between doses.
The subjects will be instructed to continue to apply the gel topically with the fingertips four 
times a day for 7 days. Dosing times should be distributed as evenly as possible over the day, 
preferably once upon first arising (i.e., after washing or shower or bath), once at lunch 
(approximately 12:00 hour), once in the late afternoon (approximately 17:00 hour), and once in 
the late evening (i.e., after washing approximately 21:00 hour). There should be a period of at 
least 4 hours between individual applications. The appropriately-labeled tube should be used 
for each application.

Subjects can take a shower or bathe prior to application. Subjects should not shower, bathe or 
wash the treated area within the first three hours after the application. Subjects should wash 
their hands after use and should wait 10 minutes before covering the treated skin with clothing. 
The investigator will instruct the subject to take the study drug exactly as prescribed and state 
that compliance is necessary for the subject’s safety and the validity of the study. The subject 
will be told to contact the investigator if he/she is unable for any reason to take the gel as 
directed/prescribed. All dosages prescribed and dispensed to the subject and all dose changes 
during the study must be recorded on the Dosage Administration Record CRF. Any missed or 
skipped doses must be recorded in CRF. 
Subjects will be instructed to self-administer their assigned product per the above usage 
instructions which will be explained and provided to the subject. 
6.2.1
Medication/Dosing Errors
Medication/dosing errors may result, in this study, from the administration or consumption of: 

the wrong product,

by the wrong subject, 

at the wrong time, 

or at the wrong dosage. 
Such medication/dosing errors occurring to a study subject are to be captured in the CRF.  In 
the event of medication dosing error, the sponsor should be notified immediately.
Medication/dosing errors are reportable irrespective of the presence of an associated AE, 
including:

Medication/dosing errors involving subject exposure to any of the study products;

Potential medication/dosing errors or uses outside of what is foreseen in the protocol 
that do or do not involve the participating subject.
If a medication/dosing error is accompanied by an AE, as determined by the investigator, the 
medication/dosing error and, any associated adverse event(s) are to be captured in the CRF AE 
form. 
6.3
Investigational/Study Product Storage 
The investigator, or designee, will ensure that all study products are stored in a secured area 
with controlled access under required storage conditions and in accordance with applicable 
regulatory requirements and the product label.  
Site systems must be capable of measuring and documenting (for example, via a log), at a 
minimum, daily minimum and maximum temperatures for all site storage locations (as 
applicable, including frozen, refrigerated, and/or room-temperature products).  This should be 
captured from the time of first product receipt throughout the study.  Even for continuous 
monitoring systems, a log or site procedure that ensures active daily evaluation for excursions 
should be available.  The operation of the temperature-monitoring device and storage unit (for 
example, refrigerator), as applicable, should be regularly inspected to ensure it is maintained in 
working order.

Any excursions from the product-label storage conditions should be reported to appropriate site 
staff upon discovery and communicated to sponsor as soon as possible.  The site should actively 
pursue options for returning the product to the storage conditions as described in the labeling, 
as soon as possible.  Excursions from the storage requirements, including any actions taken, 
must be documented as a protocol deviation and reported to the Sponsor.  
Once an excursion is identified, the affected product (or products) must be quarantined and not 
used until the sponsor provides documentation of permission to use. Use of any of the affected 
product(s) prior to sponsor approval will be considered a protocol deviation.  
Site staff will instruct subjects on the proper storage requirements for all take-home products. 
6.4
Investigational/Study Product Accountability
All products supplied are for use only in this clinical study and should not be used for any other 
purpose.
All study products must be received by a designated person at the study sites, handled and stored 
safely and properly, and kept in a secured location to which only the study staff have access. 
Upon receipt, all study products should be stored according to the instructions specified on the 
product labels (Table 6-1,Table 6-2) . Study products are to be dispensed only to subjects 
enrolled in the study in accordance with the protocol, by authorized site staff.
The investigative site must maintain adequate records documenting the receipt, use, loss, or 
other disposition of all the product supplies. All study products will be accounted for using the 
investigational/study product accountability form/record. The investigator is responsible for 
study product accountability, reconciliation, and record maintenance. 
The accountability records must be available for inspection by the study monitor during the 
study. Monitoring of product accountability will be performed by the monitor during site visits 
and at the completion of the study. 
All unused product must be returned at the final Visit 4. The monitoring plan will describe the 
process for investigational product accountability.
The inventory must be available for inspection by the study monitor during the study. 
6.4.1
Destruction of Investigational/Study Product Supplies 
At the conclusion of the study, the Principal Investigator or an appropriate designee, and a 
representative of GSK CH (study monitor) will inventory all used and unused study products 
and sundry items. The investigational/study product accountability record for returned study 
products will then be completed. All study product (used and unused) for this clinical study 
(including emptying containers) will be returned for destruction to the GSK CH Clinical 
Supplies Department or designated vendor using the return instructions provided. 
6.5
Blinding and Allocation/Randomization
At Visit 1, participants who fulfill all the inclusion criteria and none of the exclusion criteria 
will be assigned a unique randomization number in ascending numerical order at each study 
site. The randomization number encodes the participant’s assignment to one of the two arms of 
the study according to the randomization schedule generated prior to the study. These 
randomization numbers are linked to the two treatment arms, which in turn are linked to 
container (kit) numbers. A separate container list will be produced. Subjects will be randomized

using an interactive response technology system and container numbers will be provided by the 
system.
Subjects will be randomized in a 1:1 ratio, with equal numbers receiving DDEA 2.32% + 
Placebo gel and DDEA 1.16% gel. Randomization numbers will be assigned to individual 
centers in order to stratify the randomization by center.
Before the study is initiated, training, login information and directions for the IRT will be 
provided to each site. Study products will be dispensed according to the instruction received 
through the IRT at the appropriate study visits.
Returned study products should not be re-dispensed to any subject.
The investigator’s knowledge of the product allocation should not influence the decision to 
enroll a particular subject or affect the order in which subjects are enrolled.
This study is described as double-blind (the subjects and clinical examiner will be blinded to 
the product received). The study statistician, data management staff, other employees of the 
Sponsor and vendors acting on behalf of the sponsor, who may influence study outcomes will 
also be blinded to the product allocation. The placebo gel and active gels will be identical in 
packaging, labeling, odor, schedule of administration, and as identical as possible in appearance.
To ensure the examiner remains blinded throughout the study, staff involved in the preparation, 
dispensing, and application of study products will work in a separate area. The examiner is not 
permitted in any area where study product is stored, dispensed, or in use. 
Subjects will be instructed not to remove study products from the opaque bags provided outside 
of the dispensing room, while at the study site. Dispensing staff and staff supervising 
administration of IP will not be involved in any efficacy/safety assessment procedures during 
the study.  
Randomization data will be kept strictly confidential, accessible only to authorized persons, 
until the time of unblinding. After the study is completed, the data file verified, and protocol 
violations determined, drug codes will be broken and made available for data analysis.
6.6
Breaking the Blind
At the initiation of the study, the study site will be instructed on the method for breaking the 
blind.  The method will be an electronic process.
The electronic system will be programmed with blind-breaking instructions. In case of an 
emergency, the investigator has the sole responsibility for determining if unblinding of a 
subject’s product assignment is warranted. Subject safety must always be the first consideration 
in making such a determination. If the investigator decides that unblinding is warranted, the 
investigator should make every effort to contact the sponsor prior to unblinding a subject’s 
product assignment unless this could delay emergency treatment of the subject.
If a subject’s product assignment is unblinded, the sponsor must be notified within 24 hours 
after breaking the blind. The date and reason that the blind was broken must be recorded in the 
source documentation and case report form, as applicable.
Any AE associated with breaking the blind must be recorded and reported as specified in this 
protocol. The study site may also be required to inform the IRB/EC if the blind is broken.

6.7
Subject Compliance
The first dose of study products will be administered by investigator site personnel in order to 
demonstrate proper application of the treatments. 
The subject will return the trial medication (used or unused) at every visit and the investigator 
will record the number of study drug applications for each tube separately for morning, noon, 
late afternoon and late evening in the CRF. The returned tubes will be weighed with the cap and 
the weight will be recorded in mg on the drug accountability form in the CRF. Applying 2 g per 
use, the weight of each tube will decrease by approximately 2 g each study day.
If it appears that the subject used too little or too much study drug, the subject will be re-
instructed about the correct application technique by the investigator or the study nurse. 
At the last visit, the subject will return the tubes to the investigator who will store them until 
the monitor arranges for their return. The investigator must not destroy any drug.
In addition, a diary will be supplied to promote compliance and to capture details of product 
use throughout the study period. Subjects may also record additional information such as AEs 
or medications used. Any additional details relevant to efficacy or safety should be reviewed 
by the investigator (or suitably qualified designee) with the subjects at each visit and transcribed 
to the CRF as appropriate.
6.8
Subject Diary
A diary will be handed out to the subject at Visit 1,Visit 2, and Visit 3.

Every time gel is applied, the subject must document the time and date of application. 
This includes gel applied at the clinic site

Pain intensity and pain relief will both be assessed by the subjects every 2 hours ± 30 
minutes (after starting study drug) until the subject goes to bed on the evening of Day 
1. The same assessment and recording frequency will also be followed starting with the 
first dose on Day 5. On Day 1 and Day 5 where an assessment time point coincides with 
a dosing time point, the assessment of pain intensity and pain relief should be made prior 
to the dose. For all other time periods, pain intensity and pain relief will be assessed and 
recorded immediately prior to each study drug application.

Every time rescue medication is taken (not allowed within 6 hours of Study Visits and 
within 12 hours of Study Visit 3), the subject must document:
o
Time and date of rescue medication
o
Number of tablets taken
o
Reason for use of rescue medication
o
Pain intensity and pain relief immediately prior to each dose of rescue 
medication
The Investigator or designee will ensure that all diary entries completed by the subject are
legible. The Investigator will review the diary at each clinic visit. The diary handed out to 
subjects on Visit 1, Visit 2, and Visit 3 will be collected by the Investigator or designee at Visit 
2, Visit 3, and Visit 4 (Day 8±1) respectively.

6.9
Concomitant Medication/Treatment(s)
As a general rule, no concomitant medications should be taken during the study, especially 
those medications prohibited by the exclusion criteria. Special attention should be given to the 
prohibited use of systemic or topical NSAIDs from the time of Screening up to Visit 4– as these 
are the basis for subject exclusion.
Concomitant therapies prohibited during the study: 
• Analgesics since the injury, administered by any route (i.e., topical, oral, rectal, injected,  
or inhaled), except rescue medication as described in Section 6.10, and acetylsalicylic acid 
taken for at least 30 days on a stable daily dose (≤ 162 mg) for non-analgesic reasons. Pain 
medication taken prior to the injury must be washed out for at least 24 hours before 
randomization. The following concomitant medications and/or therapies are prohibited:
•  Systemic or topical NSAIDs;
• Steroids (injected or oral, except inhaled topical asthma and hayfever treatments and 
topical dermal treatments not applied to the sprained ankle); 
• Physiotherapy (including, but not exclusive to, transdermal electro neural stimulation 
(TENS), ultrasound, massage, and spinal manipulation) or any other kind of pain therapy 
throughout the course of the study; 
• Tranquilizers, anxiolytics, hypnotics, or sedatives, unless the subject’s prescribed daily 
dose has been unchanged for a month before the randomization visit; this regimen must 
continue unchanged for the entire study; 
• Amphetamines, barbiturates, benzodiazepines, cocaine, methamphetamines, opiates, 
phencyclidine, and tetrahydrocannabinol; 
• Traditional, herbal or homeopathy treatments (oral and topical); 
• Adhesive and/or immobilizing casts, bandages, Aircast
 splints, treatment by rest, ice, 
compression, or elevation (RICE) are not allowed. 
Subjects will receive paracetamol as rescue medication as described in Section 6.10. Use of a 
crutch and certain physician approved exercises will be allowed. The physician will instruct the 
subject to start Achilles’ tendon stretching on Day 1.
Any medications, treatments or vaccine (including over-the-counter or prescription medicines, 
vitamins, and/or herbal supplements) taken during the study, from signing the informed consent, 
must be recorded in the CRF with indication, reason for use, unit dose, daily dose, and start and 
stop dates of administration. All subjects will be questioned about concomitant 
medication/treatments at each site visit.
Medication/treatments taken within 90 days of signing the informed consent form will be 
documented as a prior medication/treatment. Medications/treatments taken after signing the 
informed consent form will be documented as concomitant medication/treatments.
Use of hormonal contraception will be allowed during the study; however, subjects must have 
been stabilized on this medication for at least 3 months prior to screening.
Subjects will be allowed to remain on any maintenance medication not excluded by the 
exclusion criteria, provided they have been stabilized on this medication for at least 3 months 
prior to screening.

Rescue Medication 
The investigator will provide rescue medication (paracetamol, 500 mg tablets) to the subject at 
the baseline visit. Rescue medication will be re-dispensed on Day 5 (V3), if necessary.
Subjects will be instructed to take only the rescue medication provided for pain in the ankle or 
any other pain (e.g., headache) or fever (e.g., due to common cold) they might experience during 
the trial. One tablet may be taken, repeated after at least 4 hours, if needed, up to a maximum 
of 2000 mg (four tablets) per day. No rescue medication is allowed within 6 hours prior to the 
study visits or within 12 hours of Study Visit 3.
The subject will receive a Subject Diary at Visit 1, Visit 2, and Visit 3 to record the information 
described in Section 6.8. At each visit, the investigator or designee will review the rescue 
medication use recorded in the diary and will transfer the relevant information to the CRF. 
Empty packages and rescue medication not used will be returned to the investigator. The 
investigator or designee will then compare the packages vs. the subject’s rescue medication 
form and any discrepancies will be noted in the CRF. 
The investigator will further investigate any instances in which rescue medication was taken 
for reasons other than ankle sprain and complete the Adverse Event Form, if appropriate.

DISCONTINUATION OF STUDY INTERVENTION AND 
SUBJECT DISCONTINUATION/WITHDRAWAL
7.1
Subject Discontinuation/Withdrawal 
A subject may withdraw from the study at any time at his or her own request or may be 
withdrawn at any time at the discretion of the investigator or sponsor for safety, behavioral 
reasons, or the inability of the subject to comply with the protocol-required schedule of study 
visits or procedures.  
The following circumstances require discontinuation of study product and/or premature subject 
withdrawal:

Protocol violation that may impact the subject’s safety

Withdrawal of informed consent

Subject lost to follow-up 

Unblinding of the subject 

Pregnancy
If a subject is discontinued or prematurely withdraws from the study, the reason(s) for 
discontinuation or withdrawal and the associated date must be documented in the relevant 
section(s) of the CRF. 
7.2
Lost to Follow up
A subject 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. 
If a subject fails to return to the site for a required study visit the site must attempt to contact 
the subject and reschedule the missed visit as soon as possible and counsel the subject on the

importance of maintaining the assigned visit schedule and ascertain whether or not the subject 
wishes to and/or should continue in the study.
Before a subject is deemed lost to follow up, the investigator or designee must make every effort 
to regain contact with the subject (where possible, 3 telephone calls and, if necessary, a certified 
letter to the subject’s last known mailing address or local equivalent methods). These contact 
attempts should be documented. If contact is made with the subject, the investigator should 
inquire about the reason for withdrawal, request that the subject return all products that they 
had been dispensed and if appropriate request that the subject return for a final visit, and 
follow-up with the subject regarding any unresolved adverse events (AEs).
Final safety assessments may be carried out when the subject returns to the study site, at the 
investigator’s discretion, which could include the following:

Physical examination and vital signs;

Blood and urine specimens for safety laboratory and pregnancy tests (if applicable)
Should the subject continue to be unreachable, he/she will be considered to have withdrawn 
from the study and lost to follow up. 
Lack of completion of all or any of the early termination procedures will not be viewed as 
protocol deviations so long as the subject’s safety was preserved.
If the subject withdraws from the study and also withdraws consent for disclosure of future 
information, no further evaluations should be performed and no additional data should be 
collected.  The sponsor may retain and continue to use any data collected before such 
withdrawal of consent.

STUDY PROCEDURES
This section lists the procedures to be completed at each planned study visit.  The timing of 
each procedure is listed in the Schedule of Activities section.
Adherence to the study design requirements, including all procedures are essential and required 
for study conduct.
8.1
Visit 1/Screening / Randomization Visit
Screening procedures will be conducted by the Investigator, or suitably qualified designee.
As subjects must enter the study and receive treatment within 24 hours of injury, subjects will 
be screened and randomized within 24 hours prior to administration of the investigational 
product to confirm that they meet the subject selection criteria for the study.  
The following procedures will be completed:
8.1.1
Informed Consent
The investigator, or designee, must obtain informed consent from each subject participating in 
this study after adequate explanation of the aims, methods, objectives, and potential hazards of 
the study. Two copies of the informed consent form (ICF) will be signed and dated by the 
subject, the subject will retain one copy and the other will be kept at site.
The investigator, or designee, must also explain to the subjects that they are completely free to 
refuse to enter the study or to withdraw from it at any time.  Appropriate forms for documenting 
a signed and dated consent will be provided by either the investigator or by GSK CH.

Template Version Effective: 18-May-18 (CCR #11475)
Page 35 of 64
The investigator, or designee, should sign and date each copy of the ICF to confirm that the 
consent process was completed correctly after the subject has signed.  
The time the subject signed the informed consent form will also be captured on the Informed 
Consent Form as this is the point at which all Adverse Events will be captured from. The date 
and time of consent will be transcribed to the CRF.
If, during a subject’s participation in the study, any new information becomes available that 
may affect the subject’s willingness to participate in the study, each ongoing subject should 
receive a copy of this new information and be re-consented into the study. Each subject should 
be provided with a copy of the signed and dated amended consent form. The date of re-consent 
will be recorded on the CRF.
After signing the ICF, subjects will undergo the screening assessments to confirm that they 
meet all the inclusion criteria and none of the exclusion criteria. If the subject is confirmed 
eligible by the investigator (or designee) to participate in the study the subject is considered 
enrolled in the study.
8.1.2
Demographics
The following demographic information will be recorded in the CRF: year of birth, gender and 
race.
As an important aspect of the trial is that it be conducted in a local population, race, is an 
important element in establishing a representative population.
8.1.3
Inclusion/Exclusion Criteria
Inclusion and exclusion criteria information will be reviewed and documented in the CRF.
8.1.4
Medical History and Prior Medication/Treatment
Details of relevant medical and surgical history (in the last 5 years), including allergies or drug 
sensitivity, will be documented in the CRF. Of specific interest are diseases of the affected ankle 
or foot in the last 6 months and any concurrent injuries concerning the lower extremities.
Prior medications/treatments, including prescription and non-prescription drugs, dietary 
supplements and herbal remedies, taken in the last 90 days and prior to signing the informed 
consent form, will be documented in the CRF.
8.1.5
Subject Eligibility
The investigator and/or medically qualified designee will review inclusion/exclusion criteria, 
medical history, prior medications to confirm subject eligibility to participate in the clinical trial. 
This will be documented in the CRF.
To prepare for study participation, subjects will be instructed in the Lifestyle Guidelines 
(Section 5.5) and any Concomitant Medication/Treatment(s) (Section 6.9) requirements of the 
protocol.
8.1.6
Screening/Randomization Procedures
The following additional procedures will occur at the Screening/Randomization visit:

Examination of ankle sprain

Study Conclusion
The Study Conclusion page of the CRF will be completed for all subjects whether they 
completed all study procedures or if they were discontinued from the study early.  If the subject 
discontinued early, at any point during the study, the primary reason for withdrawal should be 
recorded on the Study Conclusion page.
If a subject has any clinically significant, study-related abnormalities or AEs at the conclusion 
of the study, the GSK CH medical monitor (or designated representative) should be notified 
and, the subject may be asked to remain at the clinical site or be asked to return for a follow-up 
visit to ensure any issue is resolved or deemed not clinically significant. 
8.4
Follow-up Visit / “Phone Call”
The study site may contact a subject to follow up an AE post-study completion/withdrawal 
and, in some circumstances, request they return to the site for additional follow-up visits (final 
safety assessments). If needed, additional examinations may be carried out at such visits.

STUDY ASSESSMENTS
Every effort should be made to ensure that protocol-required tests and procedures are completed 
as described.  However, it is anticipated that from time to time there may be circumstances, 
outside the control of the investigator that may make it unfeasible to complete an assessment.  
In these cases, the investigator must take all steps necessary to ensure the safety and well-being 
of the subject.  When a protocol-required assessment cannot be performed, the investigator (or 
designee) will document the reason for the missed assessment as a protocol deviation and any 
corrective and preventative actions that he or she has taken to ensure that required processes are 
adhered to as soon as possible.  The Sponsor must be informed of any missed assessments in a 
timely manner.
9.1
Screening Assessments
Screening assessments will be performed by appropriately trained staff/clinical examiners at 
the times, and in the order, defined in the Study Procedures section of this protocol 
9.2
Efficacy Assessments
The following efficacy assessments will be performed by appropriately trained staff/clinical 
examiners, at the times and in the order defined in the Study Procedures section of this protocol. 
For individual subjects, the examiner should remain consistent throughout the study period 
where possible.
The following chronological sequence will be observed for the assessments below:
1. Ankle swelling
2. Pain on movement

3. Tenderness
9.2.1
Ankle Swelling
Ankle swelling is evaluated at Visits 1-4 by the Figure-of-eight-method, a common procedure 
to assess ankle size. The method has been validated on healthy volunteers with an intra-class 
correlation coefficient of 0.99 for inter-tester reliability and 0.99 for intra-tester reliability 
[Tatro Adams 1995, Petersen 1999, Friends 2008].
The Figure-of-eight-method is reproduced by using bony landmarks about the ankle. Common 
sites of ankle sprain swelling are the anterior talofibular ligament, calcaneofibular ligament, 
and anterior tibiofibular ligament. Because the tape spans each of these anatomical areas, the 
figure-of-eight-method may offer a more accurate clinical assessment of ankle swelling.
In detail: a one-quarter-inch wide (about 63 mm), retractable, plastic tape measure is utilized to 
obtain the measurements of each subject’s ankle. All measurements are recorded in cm. Each 
subject is seated comfortably in a long sitting position with both feet extended beyond the end 
of the plinth in a slight dorsiflexion position. The figure of eight-method is applied to both feet 
and the tape measure is wrapped around the ankle along the following course: the beginning of 
the tape is placed midway between the tibialis anterior tendon and lateral malleolus and is then 
continued across anatomically defined points in the form of a figure of eight around the ankle 
joint (for details [Tatro Adams 1995]). The tape localization of the first measurement should be 
marked with an appropriate marker.
Each ankle is measured three times and the average is calculated. The difference in this average 
between ankles tracks the natural course of disease. 
9.2.2
Pain on Movement
The investigator will perform a manipulation of the ankle (i.e., movement) (described below), 
and the pain assessment will be done by the subject. These will occur at the study center on 
Days 1, 3, 5 and 8 (±1) (Visits 1–4) using a 100 mm VAS.
The manipulation will be performed as follows:
The subject is asked to lie down on an even horizontal surface. The investigator gently lifts the 
leg and holds it up in the air at an angle of approximately 45°. While holding the leg with one 
hand, the investigator performs a gentle inversion (i.e., supination) of the foot of the injured 
ankle to reach an angle of approx. 30°.
The extent of ankle pain is evaluated by the subject in answer to the question:
“How would you describe your ankle pain right now?”
The pain-on-movement is registered by the subject by drawing a perpendicular line on the 100 
mm VAS scale with anchors at 0 = “no pain” and 100 = “extreme pain”.
9.2.3
Tenderness
'Tenderness' is the sensation of pain expressed by a subject when pressure is applied to the body. 
A more precise term is 'pressure pain threshold', the minimum pressure required to cause pain. 
Tenderness or pressure pain threshold is one of the major palpatory signs used by practitioners 
for diagnostic and treatment assessment purposes. Tenderness can be quantified with an 
algometer (pressure pain meter). It measures the amount of pressure a subject can endure before 
a pain sensation is elicited. Algometers have been used extensively to measure the efficacy of 
therapeutic interventions for the treatment of pain [Fischer 1987, Ohrbach 1989, Galer 2000,

Template Version Effective: 18-May-18 (CCR #11475)
Page 40 of 64
Wetzel 2002, Chesterton 2003]. The reliability of repeated measurements of pressure pain 
threshold has been demonstrated [Fischer 1987, Nussbaum 1998].
Tenderness will be measured by calibrated algometers in an area of 1 cm² at the centre of the 
injured area. The position of measurement will be marked with a water resistant marker on 
subjects’ skin to ensure consistent measuring points throughout the study. The investigator will 
apply the pressure gauge to the marked tender point of maximum sensitivity by placing the 
gauge at a 90° angle vertical to the skin.
The subject is instructed to indicate the onset of pain (pressure pain threshold) with a verbal cue 
such as "Yes" or "Stop". Measurements will be performed with covered scale so that 
investigator and subject cannot see the values. They will be evaluated after measurement.
For assessment of a treatment effect the tenderness of the treated painful area has to be 
compared with the tenderness at the corresponding anatomical position of the healthy uninjured 
contralateral side.
9.2.4
Ankle Joint Function
Evaluated by the subject at the study center at Days 1, 3, 5 and 8 (±1) (Visits 1-4) using the 
Karlsson Scoring Scale [Karlsson 1991 and 1996]. This validated scoring scale measures 
recovery of ankle joint function after an acute ligament injury. Assessments are made in the 
following eight categories (score): pain (20), swelling (10), instability (subjective) (15), 
stiffness (5), stair climbing (10), running (10), work activities (15), and the use of a support 
device (5). The total score ranges in value from 0 to 90.
9.2.5
Diary Pain Intensity and Pain Relief Assessments
Pain intensity will be assessed in the diary on a 4-point categorical scale.
“How would you describe your ankle pain right now?”
0 = “no pain”, 1 = “mild pain”, 2 = “moderate pain”, 3 = “severe pain”.
Spontaneous pain relief will be assessed in the diary on a 5-point categorical scale.
“How would you describe the relief from your ankle pain right now?”
0 = “no relief”; 1 = “a little relief”; 2 = “some relief”; 3 = “a lot of relief ”; 4 = “complete
relief”.
Pain intensity and spontaneous pain relief will both be assessed at baseline (immediately prior 
to first dose) and every 2 hours ± 30 minutes (after starting study drug) until the subject goes to 
bed on the evening of Day 1. The same assessment and recording frequency will also be 
followed starting with the first dose on Day 5. On Day 1 and Day 5 where an assessment time 
point coincides with a dosing time point, the assessment of pain intensity and pain relief should 
be made prior to the dose. For all other time periods, pain intensity and pain relief will be 
assessed and recorded immediately prior to each study drug application.
9.3
Safety and Other Assessments
The following safety assessments will be performed by appropriately trained staff/clinical 
examiners, at the times and in the order defined in the Study Procedures section of this protocol.

provided in the Investigator binder supplied to each center. The local laboratory will report 
results to the center as early as possible in order to allow the Investigator to review the results 
no later than 24 hours after blood samples being taken.
Additional laboratory results may be reported on these samples as a result of the method of 
analysis or the type of analyzer used by the clinical laboratory; or as derived from calculated 
values.  These additional tests would not require additional collection of blood.  Unscheduled 
safety lab tests may be obtained at any time during the study to assess any perceived safety 
concerns. 
9.3.2
Pregnancy Testing
For female subjects of childbearing potential, a urine pregnancy test, will be performed at Day 
1 and Day 8 ± 1. Approximately 30 mL will be collected for testing. Results will be obtained 
prior to dosing.  A female subject will be considered of non-childbearing potential if they satisfy 
at least one of the following criteria:
1. Achieved postmenopausal status, defined as follows: cessation of regular menses for at least 
12 consecutive months with no alternative pathological or physiological cause; status may be 
confirmed by a serum follicle-stimulating hormone (FSH) level confirming the 
post-menopausal state;
2. Have undergone a documented hysterectomy and/or bilateral oophorectomy;
3. Have medically confirmed ovarian failure.

All other female subjects will be considered to be of childbearing potential.
The investigator and site personnel will remind subjects at each visit to inform site personnel if 
their menstrual cycle has changed or if they have any other reason to suspect they may be 
pregnant (e.g. had unprotected intercourse since the last visit).
A negative pregnancy result is required before the subject may receive the investigational 
product.  Pregnancy tests will also be done whenever one menstrual cycle is missed during the 
active study period (or when potential pregnancy is otherwise suspected). Pregnancy tests may 
also be repeated as per request of IRBs/ECs or if required by local regulations.
In the case of a positive confirmed pregnancy, the subject will be withdrawn from 
administration of investigational product and from the study.
9.3.3
Physical Examinations 
Physical examinations may be conducted by a physician, trained physician's assistant, or nurse 
practitioner as acceptable according to local regulation.  
A general physical examination will be performed at Day 1 (randomization visit) and upon study 
termination (Day 8 ± 1 - final visit), as well as when judged necessary by the investigator. 
Examination will include: general condition, dermatologic, eyes, ears, nose, throat, neck, thyroid, 
heart, respiratory system, abdomen, kidneys, skeletal system, extremities, lymphatic system, CNS, 
neurological conditions according to the state of the art.
Any untoward findings identified on physical exams conducted after the administration of the 
first dose of investigational product will be captured as an adverse event, if those findings meet 
the definition of an adverse event.
9.3.4
Height and Weight 
Height in cm and body weight in kilograms (kg) to the nearest 0.1 kg will be measured at 
Visits 1 and 4 (height at Visit 1 only).
For measuring weight, a scale with appropriate range and resolution should be used and must 
be placed on a stable, flat surface. Subjects must remove shoes, bulky layers of clothing, and 
jackets so that only light clothing remains. They must also remove the contents of their pockets 
and remain still during measurement of weight. 
9.3.5
Vital Signs (Blood Pressure and Pulse Rate)
Vital signs (including systolic blood pressure, diastolic blood pressure and pulse rate) will be 
measured at Visits 1 and 4:
- Blood pressure: Measurement after at least 5 minutes at rest in sitting position.
- Pulse rate: Measured after at least 5 minutes at rest in the sitting position.
Additional collection times, or changes to collection times of blood pressure and pulse rate will 
be permitted, as necessary at the discretion of the investigator, to ensure appropriate collection 
of safety data.
The same properly sized and calibrated blood pressure cuff will be used to measure blood 
pressure each time. The use of an automated device for measuring BP and pulse rate is 
acceptable, although, when done manually, pulse rate will be measured in the brachial/radial 
artery for at least 30 seconds.  When the timing of these measurements coincides with a blood

ADVERSE EVENT AND SERIOUS ADVERSE EVENTS
10.1
Definition of an Adverse Event (AE)
An AE is any untoward medical occurrence in a clinical study subject, temporally associated 
with the use of a study product including any washout or lead-in product or investigational 
assessment, whether or not considered related to the study product, including any washout or 
lead-in product or investigational assessment.
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 product including any washout or lead-in product or investigational assessment.
Events Meeting the AE Definition:  

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or 
other safety assessments (e.g. ECG, radiological scans, vital sign measurements), 
including those that worsen from baseline, considered clinically significant in the 
medical and scientific judgment of the investigator (i.e., 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 product 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 
product 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. Such instances will be captured in the efficacy assessments. 
211206 | Protocol Amendment  10 Sep 2019 | TMF-29126 | 1.0

Template Version Effective: 18-May-18 (CCR #11475)
Page 44 of 64
However, the signs, symptoms, and/or clinical sequelae resulting from lack of 
efficacy will be reported as AE if they fulfill the definition of an AE. 
Events NOT meeting the AE definition: 

Any clinically significant abnormal laboratory findings (if applicable) 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 subject’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 subject’s 
condition. 

Medical or surgical procedure (e.g. endoscopy, appendectomy) is not the AE. The 
condition that leads to the procedure is an AE (e.g. appendicitis).

Situations where 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. 
10.2
Definition of a Serious Adverse Event (SAE)
A Serious Adverse Event (SAE) is a particular category of an adverse event where the adverse 
outcome is serious. If an event is not an AE per definition above, then it cannot be an SAE even 
if serious conditions are met (e.g. hospitalization for signs/symptoms of the disease under study, 
death due to progression of disease).
A serious adverse event is any untoward medical occurrence at any dose that:

Results in death

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;

Requires inpatient 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 
physician’s office or outpatient setting. Complications that occur during 
hospitalization are AEs. If a complication prolongs hospitalization or fulfills 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.

Results in persistent or significant 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 with or 
prevent everyday life functions but do not constitute a substantial disruption

Results in congenital anomaly/birth defect

Other situations:

Medical or scientific judgment should be exercised in deciding whether SAE 
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 events 
should usually be considered serious.

Examples of such events include 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.
Note: Classification of an AE as ‘serious’ is based on the outcome of the event, and is a factor 
in determining reporting requirements.
10.3
Reporting of Adverse Events
10.3.1
Reporting Period 
All AEs, and therefore all SAEs will be collected immediately after a subject consents to 
participate in the study by the completion (signature) of the ICF and until 28 days following 
last administration of the study product (or last procedure). 
Medical occurrences that began before obtaining informed consent will be recorded in the 
Medical History/Current Medical Conditions section of the CRF not the AE section.
Details recorded by the subject on a diary or similar document that meet the definition of an AE 
must also be discussed with the subjects and transcribed in the AE section of the CRF. 
10.4
Reporting Procedures
The investigator and any designees are responsible for detecting, documenting and reporting 
events that meet the definition of an AE and remain responsible for following up on AEs that 
are serious, considered related to the study product(s), participation in the study, or a study 
procedure, or that caused the subject to discontinue the study product or study. 
The investigator (or medically qualified designee) is to report all directly observed AEs and all 
AEs spontaneously reported by the study subject. In addition, each study subject will be 
questioned about AEs. 
Each AE is to be assessed to determine if it meets the criteria for a SAE.  If an SAE occurs, 
expedited reporting will follow local and international regulations, as appropriate.
When an AE occurs, it is the responsibility of the investigator (or medically qualified designee) 
to review all documentation (e.g. hospital progress notes, laboratory, and diagnostics reports) 
related to the event.
The investigator or site staff will then record all relevant information regarding an AE in the 
CRF and all details relating to an SAE in the SAE Form provided.

It is not acceptable for the investigator (or medically qualified designee) to send photocopies 
of the subject’s medical records to GSK CH in lieu of completion of the AE CRF page/SAE 
form.
There may be instances when copies of medical records for certain cases are requested by GSK 
CH.  In this instance, all subject identifiers, with the exception of the subject number, will be 
redacted on the copies of the medical records prior to submission to GSK CH.
The investigator (or medically qualified designee) will attempt to establish a diagnosis of the 
event based on signs, symptoms, and/or other clinical information.  The diagnosis will be the 
documented as the AE/SAE where known and not the individual signs/symptoms. (e.g. upper 
respiratory tract infection, seasonal allergy, etc. instead of runny nose).
AEs elicited by the investigator (or medically qualified designee) in a standard manner at the 
study visits should also be recorded in the AE section of the CRF and/or using the SAE form 
(subject to the classification of the AE). Care will be taken not to introduce bias when 
questioning a subject about any changes in their health. Open-ended and non-leading verbal 
questioning should be used.
10.4.1
Reporting of an Adverse Event
All AEs will be reported on the AE page of the CRF by the investigator or site staff.  It should 
be noted that the form for collection of SAE information is not the same as the AE CRF.  Where 
the same data are collected, the AE CRF page and the SAE form must be completed in a 
consistent manner.  For example, the same AE term should be used on both.  AEs should be 
reported using concise medical terminology on the CRF as well as on the form for collection of 
SAE information.
10.4.2
Reporting of a Serious Adverse Event
In addition to recording the details of each AE on the AE CRF page, an SAE form should be 
completed, as fully as possible. Hard copies of the ‘paper’ SAE form will be provided in the 
investigator study master file. Original SAE forms will be retained in the investigator study 
master file.
It is essential to enter the following information: 

Protocol and subject identifiers

Subject demography

Description of events, with diagnosis if available

Investigator opinion of relationship to study product (or study procedure, if appropriate)

Criterion for seriousness.
The following are desirable and are of particular relevance for investigator and GSK CH 
assessment of the SAE report:

Date of onset of AE 

Date AE stopped, if relevant

Study product start date

Study product end date if relevant

The study monitor will perform ongoing review the of the CRFs in accordance with the 
monitoring plan, to confirm that data entered into the CRF by authorized site personnel are 
accurate, complete, and verifiable from source documents; that the safety and rights of 
participants are being protected; and that the study is being conducted in accordance with the 
currently approved protocol and any other study agreements, ICH GCP, and all applicable 
regulatory requirements.
Any queries will be generated in the EDC System to the Investigator or designee, enabling the 
errors to be addressed in parallel with Data Management review. The study monitor can also 
run reports and listings on the CRFs, to raise manual queries as needed for site clarification or

Processing Subject Reported Outcomes
Paper based subject reported outcome (PRO) data may be collected from a diary, questionnaire, 
or other specified document, etc. and entered into the data management system (DMS).  
All PRO source data should be reviewed by the study staff and the study monitor in order to 
ensure accurate transcription of data and that any potential AEs or concomitant medications 
reported on these documents are discussed with the subject and transcribed accurately to the 
CRF and/or DMS. Site staff cannot make any changes to subject diaries. If a subject makes a 
change to the subject diary, they must initial and date the change. PROs that are classed as 
source data will be retained by the investigator and true/certified copies may be sent to a 
designated vendor or GSK CH as required.
To protect the privacy of subjects, no Personally Identifiable Information (PII) (including the 
subject's name or initials or birth date) is to be recorded on any PRO/ePRO that will be 
forwarded to GSK CH or Third-Party Vendor.

STATISTICAL CONSIDERATIONS AND DATA ANALYSES
12.1
Sample Size Determination
Approximately 300 subjects will be randomized to ensure at least 240 evaluable subjects 
complete the study for the PP analysis population. A maximum of 40 randomized subjects per 
center will be allowed.
Approximately 120 subjects per treatment arm has been determined to provide 80% power to 
demonstrate non-inferiority of DDEA 2.32% gel b.i.d with DDEA 1.16% gel q.i.d. by 
comparing the two-sided 95% CI of the difference in mean change from baseline of VAS POM 
score between the two products with the non-inferiority margin of 13 mm.  This assumes a 
treatment standard deviation of 22mm and allows for a possible small true treatment difference 
of 5mm in favor of DDEA 1.16%.
The margin of 13 mm (on a 100 mm VAS scale) was chosen as the literature reported minimally 
important clinical difference for an acute musculoskeletal injury (Todd et al 1995), with 
treatment differences smaller than 13mm considered as not clinically important.  The standard 
deviation was obtained from a previous placebo-controlled ankle sprain study VOPO-P-307 
with DDEA 2.32% gel.

12.2
Statistical Methods and Analytical Plan
Additional details of the proposed statistical analysis will be documented in the statistical 
reporting and analysis plan (RAP), which will be written following finalization of the protocol 
and prior to study unblinding.
12.2.1
Definition of Analysis Populations
The safety population will include all subjects who are randomized and have received at least 
one dose of investigational product.
The modified intent-to-treat (mITT) population will consist of all randomized subjects who 
have at least one post baseline POM VAS assessment
The PP population includes all subjects from the mITT population who do not have any major 
protocol deviations that could confound the interpretation of the efficacy analyses. Protocol 
deviations that would exclude subjects from the PP population are defined in Section 12.2.2.
Before the study is unblinded, each actual post-baseline visit will be mapped to the target visit date 
to which it is chronologically closest. This corresponds to the following visit windows: Visit 2 (Days 
2–4), Visit 3 (Days 4–6), Visit 4 (Days 7+). The numbering of the actual visits (from Visit 1 to Visit 
4) will then be changed as needed to improve the correspondence of the actual visit dates to the 
protocol-specified schedule of visits, particularly in relation to Visit 3 (primary). Final 
determinations will also be made and documented before the study is unblinded to address visits 
that occur on Day 4 (which maps to two visit windows) or visits occurring well beyond the target 
date for the final visit or any other irregularities. Further detail is provided in the statistical analysis 
plan. 
12.2.2
Exclusion of Data from Analysis 
Exclusion of any data from the analyses will be determined during a Blind Data Review 
Meeting prior to database lock. Any reasons for exclusion from an analysis population will be 
listed, if applicable.  
Protocol deviations that would exclude subjects from the PP population may include (but are 
not limited to) the following:

Subjects failing to meet inclusion and exclusion criteria but were included in the study.

Subjects without a Day 5 pain on movement VAS assessment

Subjects with poor or moderate compliance with study treatment

Subjects taking prohibited medication 

Subjects identified with other major protocol deviations 
Further detail is provided in the statistical analysis plan.
12.2.3
Demographic and Baseline Characteristics
Demographic data, including age, gender and race, and other baseline data will be presented 
using descriptive statistics. 
Categorical variables will be summarized by the number and percentage of subjects with each 
relevant characteristic. Continuous variables will be summarized by calculating the mean, 
standard deviation, median, minimum and maximum.

12.2.4
Study Drug/Product Compliance and Use of Other Therapies
12.2.4.1 Study Drug/Product Compliance
Compliance is defined in terms of the total weight of study medication used and total number 
of applications made as follows:
• Good: > 80% of the gel has been applied and > 80% of scheduled applications made,
• Moderate: not Good and not Poor
• Poor: < 50% of the gel has been applied or < 50% of scheduled applications made.
The % of gel used will be computed relative to the actual number of applications made from 
randomization through the final visit multiplied by 2 g. This value is to be recorded in the CRF. 
Scheduled applications will include all scheduled applications through the day before the final 
visit. On day 1, the percentage of gel used will be calculated based on the possible number of 
administrations on that day. If only 3 were possible, then 100 % compliance on that day will be 
considered 3 applications.
Compliance will be summarized descriptively as (1) % of scheduled applications made, (2) % 
of gel used relative to number of actual applications * 2g, and (3) compliance category 
(Good/Moderate/Poor). Exposure to study drug will be summarized descriptively as (1) number 
of applications made and (2) total amount of gel used.
For subjects applying active gel only twice per day (DDEA 2.32%), and additional compliance 
and exposure computation will be performed relative to the tubes and applications of active gel.
12.2.4.2 Prior and Concomitant Medications
Prior and concomitant medications will be listed in the safety population. Concomitant 
medications will be summarized by preferred term, and the number and percentage of subjects 
who took any concomitant medication, will be presented.
12.2.5
Primary Analysis(es) 
The primary efficacy endpoint will be change from baseline in POM on Day 5 of treatment as 
assessed by a 100 mm VAS scale.
The following primary non-inferiority hypothesis will be tested for DDEA 2.32% vs DDEA 
1.16%:
The null hypothesis is Diclofenac 2.32% DDEA Gel administered BID is inferior to Diclofenac 
1.16% DDEA gel administered QID with the alternative hypothesis being Diclofenac 2.32% 
DDEA Gel administered BID is non-inferior to Diclofenac 1.16% DDEA gel administered QID.
Diclofenac 2.32% DDEA Gel administered BID will be declared non-inferior to Diclofenac 
1.16% DDEA gel administered QID if the upper limit of the two-sided 95% confidence interval 
of the difference between their mean changes from baseline VAS POM responses is less than 
the established margin of 13 mm.
The primary analysis will be based on an analysis of covariance (ANCOVA) with treatment 
and center as factors and baseline value as a covariate to estimate the treatment difference two-
sided 95% confidence interval for the primary endpoint to assess non-inferiority, using the per 
protocol and mITT analysis populations.

Evidence of a treatment-by-center interaction will be assessed by adding a factor for this 
interaction in a separate additional analysis model of the primary endpoint. If there is evidence 
of an interaction (p<0.05), then the primary endpoint outcome will also be summarized by 
center for further investigation and assessment
12.2.6
Secondary Analysis(es)
Secondary outcome measures (endpoints) include:

Change from baseline of POM on VAS on Days 3 and 8 respectively

Tenderness measured by pressure algometry on Days 3, 5 and 8 (change from baseline 
and difference between the measurement in injured area and contralateral area)

Change from baseline Ankle Joint Function (Karlsson Scoring Scale) on Days 3, 5 and 
8

Circumference measurement of swelling (change from baseline in circumference of 
affected ankle and comparison to non- affected ankle by Figure of Eight method on 
Days 3, 5 and 8)

Pain Intensity and Pain Relief 
o
Sum of Pain Intensity Difference (SPID) – From hours 0 – 24 post first dose 
(corresponding to Day 1) and from hours 96 – 120 post first dose (corresponding 
to Day 5)
o
Total Pain Relief (TOTPAR)– From hours 0 – 24 post first dose (corresponding 
to Day 1) and from hours 96 – 120 post first dose (corresponding to Day 5)
TOTPAR and SPID will be calculated as weighted sums of the Pain Relief Score and Pain 
Intensity Difference at each timepoint respectively:
TOTPAR = ΣRtx (timet – timet-1)
Where Rt = the pain relief score at time t and timet = time in hours post first dose
SPIDt = ΣPIDt (timet – timet-1)(h)
Where PI is pain intensity

Use of rescue medication, for ankle sprain and overall
o
Total number of tablets used
o
Total number of days on which rescue medication was used
Figures will show the time course of outcomes by treatment group for key quantitative outcomes. 
For POM, Karlsson score, tenderness, swelling and diary assessments (SPID and TOTPAR), 
an ANCOVA model including treatment group and center as main effects, and the baseline 
value as covariate (those outcomes for which there is a baseline) will be used for analysis, with 
the treatment difference and 95% confidence interval (two-sided) presented for each assessment.
Use of rescue medication (number of tablets and days used) will be compared between 
treatments using the CHM method (modridit scores) stratified by center, with the median 
treatment differences and 95% confidence intervals (2-sided) presented using Hodges-Lehmann 
estimation.
These secondary endpoints will be analyzed using the per protocol and mITT populations.

Safety Analysis(es)
Safety variables will be summarized on the safety population.
Exposure to study drug (number of applications, total weight of gel used) will be summarized 
by treatment group.
Treatment Emergent adverse events (TEAE, i.e. AEs that start or worsen after first study 
treatment administration) will be summarized by presenting, for each treatment group, the 
number and percentage of subjects having any TEAE, any TEAE in each MedDRA primary 
System Organ Class (SOC) and having each individual TEAE (using MedDRA preferred term). 
This will be done separately for all TEAEs and for TEAEs that are suspected to be drug-related. 
All TEAEs will also be tabulated in corresponding fashion by severity. Any other information 
collected (e.g. action taken, duration, outcome, seriousness) will be listed as appropriate. 
All adverse events (prior to treatment and treatment emergent) will be listed.
Chemistry and hematology results at Visit 1 and at Visit 4 will be summarized by the mean, 
standard deviation, median, minimum and maximum values in each treatment group. Shift 
tables (between Visit 1 and Visit 4) will also be presented. Laboratory normal ranges and all 
laboratory test results will be listed.
Vital signs (systolic and diastolic blood pressure, pulse rate, respiratory rate) recorded at Visit 
4 and changes in vital signs from Visit 1 (baseline) to Visit 4 will be summarized by the mean, 
standard deviation, median, minimum and maximum values in each treatment group. Vital signs 
at each assessment will also be listed.
12.2.8
Other Analysis(es)
Not applicable.
12.2.9
Handling of Dropouts and Missing Data 
Multiple imputation using a simulation-based statistical technique for handling missing data as 
proposed by [Rubin, 1987] will be used. Multiple imputation will consist of three steps:
1.
Imputation step. Missing values will be identified and replaced by a random sample of 
plausible values imputations (completed datasets). Under assumption of monotone missingness 
an imputation model with regression baseline parameters will be applied. Five imputed datasets 
have traditionally been suggested to be sufficient on theoretical grounds, but 50 datasets seem 
preferable and will be used to reduce sampling variability from the imputation process.
2.
Completed-data analysis (estimation) step. The desired analysis will be performed 
separately for each dataset generated during the imputation step, following the ANCOVA 
method described in section 12.2.5.
3.
Pooling step. The results obtained from each completed-data analysis will be combined 
into a single multiple-imputation result.
A sensitivity analysis will also be performed with no imputations for missing data and using a 
repeated measure mixed effect model with subject as random, and with center, treatment and 
timepoint (Day 3, 5 and 8) as factors and baseline value as a covariate. The treatment differences 
and two-sided 95% CIs for the primary end-point will be estimated for the PP and mITT analysis 
populations.
No imputation is planned for missing diary card pain intensity and relief assessments.

STUDY GOVERNANCE CONSIDERATIONS
13.1
Quality Control 
In accordance with applicable regulations including GCP, and GSK CH procedures, GSK CH 
or designee (i.e. third-party vendor) monitors will contact the site prior to the start of the study 
to review with the site staff the protocol, study requirements, and their responsibilities to satisfy 
regulatory, ethical, and GSK CH requirements.
When reviewing data collection procedures, the discussion will include identification, 
agreement and documentation of data items for which the CRF will serve as the source 
document.
GSK CH or designee will monitor the study and site activity to verify that the:

Data are authentic, accurate, and complete.

Safety and rights of subjects are being protected.

Study is conducted in accordance with the currently approved protocol and any other 
study agreements, GCP, and all applicable regulatory requirements.
The extent and nature of monitoring will be described in a written monitoring plan on file at 
GSK CH. The investigator (or designee) agrees to allow the monitor direct access to all relevant 
documents and agrees to co-operate with the monitor to ensure that any problems detected in 
the course of these monitoring visits are resolved.
13.2
Quality Assurance
To ensure compliance with GCP and all applicable regulatory requirements, GSK CH may 
conduct a quality assurance assessment and/or audit of the site records, and the regulatory 
agencies may conduct a regulatory inspection at any time during or after completion of the study. 
In the event of an assessment, audit or inspection, the investigator (and institution) must agree 
to grant the advisor(s), auditor(s) and inspector(s) direct access to all relevant documents and 
to allocate their time and the time of their staff to discuss the conduct of the study, any 
findings/relevant issues and to implement any corrective and/or preventative actions to address 
any findings/issues identified.
The investigator(s) will notify GSK CH or its agents immediately of any regulatory inspection 
notification in relation to the study. Furthermore, the investigator will cooperate with GSK CH 
or its agents to prepare the study site for the inspection and will allow GSK CH or its agent, 
whenever feasible, to be present during the inspection. The investigator will promptly apply 
copies of the inspection finding to GSK CH or its agent. Before response submission to the 
regulatory authority, the investigator will provide GSK CH or its agents with an opportunity to 
review and comment on responses to any such findings. 
The sponsor will be available to help investigators prepare for an inspection.

13.3
Regulatory and Ethical Considerations
13.3.1
Institutional Review Board/ Ethics Committee 
It is the responsibility of the investigator to have prospective approval of the study protocol, 
protocol amendments, informed consent documents, investigator brochure/safety statement 
(including any updates) and other relevant documents, e.g. recruitment advertisements, if 
applicable, from the IRB/EC.  All correspondence with the IRB/EC should be retained in the 
investigator file.  Copies of IRB/EC approvals should be forwarded to GSK CH prior to the 
initiation of the study, and also when subsequent amendments to the protocol are made.
The only circumstance in which an amendment may be initiated prior to IRB/EC approval is 
where the change is necessary to eliminate apparent immediate hazards to the subjects.  In that 
event, the investigator must notify the IRB/EC and GSK CH in writing immediately after the 
implementation.
13.3.2
Ethical Conduct of the Study
The study will be conducted in accordance with legal and regulatory requirements, as well as 
the general principles set forth in the International Ethical Guidelines for Biomedical Research 
Involving Human Subjects (Council for International Organizations of Medical Sciences 2002), 
International Ethical Guidelines for Health-Related Research Involving Humans (Council for 
International Organizations of Medical Sciences, 2016), guidelines for GCP (ICH 1996 and 
revision 2), and the Declaration of Helsinki (World Medical Association 2013). 
In addition, the study will be conducted in accordance with the protocol, the ICH guideline on 
GCP, and applicable local regulatory requirements and laws.
13.3.3
Subject Information and Consent
All parties will ensure protection of subject personal data and will not include subject names or 
other identifiable data in any reports, publications, or other disclosures, except where required 
by laws. 
When study data are compiled for transfer to GSK CH and other authorized parties, subject 
names, addresses, and other identifiable data will be replaced by numerical codes based on a 
numbering system provided by GSK CH/CRO in order to de-identify study subjects.  
The study site will maintain a confidential list of subjects who participated in the study, linking 
each subject’s numerical code to his or her actual identity.  In case of data transfer, GSK CH 
will maintain high standards of confidentiality and protection of subjects’ personal data 
consistent with applicable privacy laws.
The informed consent documents must be in compliance with ICH GCP, local regulatory 
requirements, and legal requirements, including applicable privacy laws.
The informed consent documents used during the informed consent process must be reviewed 
and approved by the sponsor, approved by the IRB/EC before use, and available for inspection.
The investigator must ensure that each study subject, is fully informed about the nature and 
objectives of the study and possible risks associated with participation. 
13.3.4
Subject Recruitment 
Advertisements approved by IRBs/ECs and investigator databases may be used as recruitment 
procedures.  Use of ethics committee approved, generic, prescreening questionnaire to assess

basic subject characteristics to determine general eligibility for this study is allowed.  This 
generic questionnaire may be used by sites as a phone script and/or to review internal databases 
to identify subjects.  
GSK CH will have an opportunity to review and approve the content of any study recruitment 
materials directed to potential study subjects before such materials are used. 
13.3.5
Reporting of Safety Issues and Serious Breaches of the Protocol or 
ICH GCP 
Within GSK CH a serious breach is defined as a breach likely to affect to a significant degree 
the safety and rights of a subject or the reliability and robustness of the data generated in GSK 
CH-sponsored human subject research studies. 
In the event of any prohibition or restriction imposed (i.e., clinical hold) by an applicable 
competent authority in any area of the world, or if the investigator is aware of any new 
information that might influence the evaluation of the benefits and risks of the investigational 
product, GSK CH should be informed immediately. 
In addition, the investigator will inform GSK CH immediately of any urgent safety measures 
taken by the investigator to protect the study subjects against any immediate hazard, and of any 
serious breaches of this protocol or of ICH GCP that the investigator becomes aware of.
13.4
Posting of Information on Publicly Available Clinical Trial 
Registers
Study information from this protocol will be posted on publicly available clinical trial registers 
before enrollment of subjects begins in accordance with applicable GSK CH processes.
GSK intends to make anonymized subject-level data from this trial available to external 
researchers for scientific analyses or to conduct further research that can help advance medical 
science or improve subject care. This helps ensure the data provided by trial participants are 
used to maximum effect in the creation of knowledge and understanding
13.5
Provision of Study Results to Investigators
Where required by applicable regulatory requirements, an investigator signatory will be 
identified for the approval of the clinical study report.  The investigator will be provided 
reasonable access to statistical tables, figures, and relevant reports and will have the opportunity 
to review the complete study results at a GSK CH site or other mutually-agreeable location.
GSK CH will also provide the investigator with the full summary of the study results.  The 
investigator is encouraged to share the summary results with the study subjects, as appropriate.
The procedures and timing for public disclosure of the results summary and for development of 
a manuscript for publication will be in accordance with GSK CH Policy.
A manuscript will be progressed for publication in the scientific literature if the results provide 
important scientific or medical knowledge.
13.6
Records Retention
Following closure of the study, the investigator must maintain all site study records (except for 
those required by local regulations to be maintained elsewhere), in a safe and secure location.

Template Version Effective: 18-May-18 (CCR #11475)
Page 59 of 64
The records (study/ site master file) must be maintained to allow easy and timely retrieval, when 
needed (e.g. for a GSK CH audit or regulatory inspection) and must be available for review in 
conjunction with assessment of the facility, supporting systems, and relevant site staff.
Where permitted by local laws/regulations or institutional policy, some or all of these records 
can be maintained in a format other than hard copy (e.g. microfiche, scanned, electronic); 
however, caution needs to be exercised before such action is taken. 
The investigator must ensure that all reproductions are legible and are a true and accurate copy 
of the original and meet accessibility and retrieval standards, including re-generating a hard 
copy, if required.  Furthermore, the investigator must ensure there is an acceptable back-up of 
these reproductions and that an acceptable quality control process exists for making these 
reproductions.
The investigator must assure that the subject’s anonymity will be maintained.  On CRFs or other 
documents submitted to GSK CH, subjects should not be identified by their names or initials, 
but by an identification code. The investigator should keep a separate log of subjects’ codes, 
names and addresses.  Documents not for submission to GSK CH, e.g. subjects’ written consent 
forms, should be maintained by the investigator in strict confidence.
Records and documents, including signed ICF, pertaining to the conduct of this study must be 
retained by the investigator for 15 years from the issue of the final Clinical Study Report (CSR) 
or equivalent summary, unless local regulations or institutional policies require a longer 
retention period. The minimum retention time will meet the strictest standard applicable to that 
site for the study, as dictated by any institutional requirements or local laws or regulations, GSK 
CH standards/procedures, and/or institutional requirements.  
No study document should be destroyed without a prior written agreement between GSK CH 
and the investigator. The investigator must notify GSK CH of any changes in the archival 
arrangements, including, but not limited to, archival at an off-site facility or transfer of 
ownership of the records in the event the investigator is no longer associated with the site.
13.7
Conditions for Terminating the Study 
Premature termination of this study may occur because of a regulatory authority decision, 
change in opinion of the IRB/EC, or study product safety problems, or at the discretion of GSK 
CH.  In addition, GSK CH retains the right to discontinue development of DDEA 2.32% at any 
time. For multicenter studies (if applicable), this can occur at one or more or at all sites.  
If a study is prematurely terminated, GSK CH will promptly notify the investigator.  After 
notification, the investigator must promptly contact all participating subjects and should assure 
appropriate therapy/ follow-up for the subjects.  As directed by GSK CH, all study materials 
must be collected and all CRFs completed to the greatest extent possible. Where required by 
the applicable regulatory requirements, GSK CH should inform the regulatory authority(ies) 
and the investigator should promptly inform the IRB/EC and provide the IRB/EC a detailed 
written explanation of the termination or suspension. 
If the IRB/EC terminates or suspends its approval/favorable opinion of a trial, the investigator 
should promptly notify the GSK CH and provide GSK CH with a detailed written explanation 
of the termination or suspension.
Upon completion or premature discontinuation of the study, the GSK CH monitor will conduct 
site closure activities with the investigator or site staff, as appropriate, in accordance with 
applicable regulations including GCP, and GSK CH Standard Operating Procedures.
