PROTOCOL SUMMARY 
Background and Rationale:
Nicotine replacement therapy (NRT) has proven to be an effective aid to smoking cessation 
by reducing nicotine withdrawal symptoms associated with smoking cessation.  There are 
several oral NRT options available, in a range of formats and flavors to address customer 
preferences.
GlaxoSmithKline Consumer Healthcare (GSKCH) markets a nicotine mini lozenge (Nicorette 
Minis), which is a therapeutic equivalent to the larger lozenge (Nicorette), with the added 
benefit of quicker dissolution.  The current mini lozenge has a mint flavor. In order to offer 
the consumer with a mini lozenge with better tasting aesthetics, a new nicotine prototype  
mini lozenge has been developed.  To confirm that the new prototype mini lozenge delivers 
the same nicotine blood profile, a bioequivalence study will need to be performed comparing 
this new prototype mini lozenge to the currently marketed mini mint lozenge (Nicorette 
Minis), which have been identified as the appropriate Reference Standard (RLD).  This 
investigation will be conducted to confirm the bioequivalence of the 2 mg nicotine prototype 
mini lozenge to the 2 mg mini mint lozenge (Nicorette Minis).
Objectives and Endpoints
Primary objectives:

To assess the bioequivalence of the nicotine 2 mg prototype mini lozenge with the 
2 mg nicotine polacrilex mini lozenge (Nicorette), in terms of nicotine AUC0-t, AUC0-
inf and Cmax
Primary endpoints

AUC0-t --Area under the plasma concentration versus time curve from time zero to 
time t, where t is the time of the last measurable plasma concentration of nicotine, 
estimated.

AUC0-inf --Area under the plasma concentration versus time curve from time zero 
extrapolated to infinity.

Cmax --The highest observed plasma nicotine concentration.
Secondary objectives

To compare the nicotine 2 mg prototype mini lozenge to the 2 mg nicotine polacrilex 
mini mint lozenge (Nicorette Minis) in terms of tmax, t½, and Kel 

To evaluate the safety of the nicotine 2 mg prototype mini lozenge
Secondary endpoints

tmax, the time of the maximum plasma concentration

t1/2, the plasma half life

Kel, the elimination rate constant

Safety assessments consists of monitoring and recording adverse events (AEs) and 
clinical safety laboratory test
Study Design

This study will be a single center, randomized, open label, single dose, two-way 
crossover in healthy smokers.  

Each subject will be treated with a single dose of the two study treatments in a 
randomized sequence.

Subjects will be confined in the study facility for approximately 60 hours during each 
study session (for 36 hours pre dosing and for 24 hours post dosing) during which 
pharmacokinetic (PK) blood samples will be obtained.

Subjects are to abstain from smoking during the confinement periods and be subject to 
random measurements of expired carbon monoxide (CO) to confirm abstinence.  The 
CO levels must be  10 ppm throughout the study session.

There will be at least 5-day and not more than 7-day clinical furlough period between 
treatment periods. For each treatment period, the clinical confinement period with 
restriction of smoking is at least 36 hours prior to dosing. The reported plasma t1/2 for 
nicotine is approximately 1 to 4 hours from previous pharmacokinetics studies 
. The 36 hour smoking restriction period prior to dosing will therefore 
minimize the residual nicotine amount from smoking during previous furlough.
Type and Planned Number of Subjects
Enough healthy adult smokers will be screened to randomize forty (40) healthy adult smokers, 
to ensure that thirty-two (32) complete the entire study assuming a 20% dropout and non-
evaluable rate. The highest intra-subject CV observed in previous studies was 23%. The 
protocols that were used to select the highest CV for the sample size calculation are: 
 
 
 
 
and S6491365 (2mg nicotine polacrilex mini cherry lozenge v.s 
2mg nicotine polacrilex mini mint lozenge: Cmax =13.7%; AUC0-t =10%). A total of thirty-two 
(32) evaluable subjects will achieve a 90% power at 5% significance level. The true ratio that 
was used in the sample size calculation was 1.05.

Statistical Methods
The PK analysis set, PKAS1 will be used for the PK evaluations. PKAS1 is defined as all 
randomized subjects who completed both periods, and who had no major protocol deviations 
concerning pharmacokinetics. Subjects with baseline nicotine concentration >5% of the 
individual Cmax for either period will be excluded from the PK population.
The PK parameters that will be used in the primary analyses are AUC0-t, AUC0-inf and Cmax.
The null and alternative hypotheses to be tested in the primary analyses are:
H0: The (geometric) mean AUC0-t (likewise AUC0-inf  and Cmax) of nicotine prototype mini 
lozenge 2mg (Test) is less than 80% or greater than 125% of that of Nicorette Mini Lozenge 
2mg (Reference).
H1: The (geometric) mean AUC0-t (likewise AUC0-inf and Cmax) of nicotine prototype mini 
lozenge 2mg (Test) is between 80% and 125% of that of Nicorette Mini Lozenge 2mg 
(Reference).
A linear mixed effects model will be fit to the log-transformed PK variables (AUC0-t, AUC0-inf 
,and Cmax), as the dependent variable, and treatment, and period as fixed effects. Subject 
nested within sequence will be a random effect. Least squares estimates of treatment effects

will be calculated and a 90% confidence interval (CI) for the treatment difference will be 
computed. The treatment difference and its CI will be exponentiated to obtain the ratio of the 
geometric means between the test and reference products and its CI.
Bioequivalence between the test and reference treatments will be concluded if the 90% 
confidence interval for the ratio of the means for each of the PK parameters AUC0-t, AUC0-inf, 
and Cmax of the nicotine profiles lie entirely within the interval 0.8 to 1.25.

INTRODUCTION
1.1
Mechanism of Action/Indication
Nicotine lozenges are indicated as an aid to smoking cessation, of tobacco dependence 
through the relief of nicotine withdrawal symptoms, including nicotine cravings in smokers.
1.2
Background and Rationale
Nicotine replacement therapy (NRT) has proven to be an effective aid to smoking cessation 
by reducing nicotine withdrawal symptoms associated with smoking cessation.  Various 
dosage forms of NRT are available, including nicotine gum, nicotine transdermal system, 
nicotine inhaler, nicotine nasal spray, nicotine sublingual tablet and nicotine lozenge.  
Variable patterns, quantities and rates of nicotine are delivered by these formulations.  One of 
the most widely used presentations is the oral administration of nicotine polacrilex, either in 
the form of a chewing gum or lozenge.  
Although effective and well tolerated the standard nicotine lozenge (Nicorette Lozenge) is 
considered by some users to be rather large and to have some unpleasant organoleptic 
properties.
The prototype mini lozenge has been developed which is smaller in size and thus more 
discrete to use as well as having improved organoleptic properties.  Nicotine is released upon 
dissolution of the lozenge in the oral cavity.  
The purpose of this study is to assess the bioequivalence of the prototype mini lozenge to the 
reference product nicotine polacrilex mini lozenge (Nicorette Minis). 
Complete information for this compound may be found in the single reference safety 
document (SRSD), which for this study is the IB. 
The SRSD for the comparative agent is the Drug Facts Label.

STUDY OBJECTIVES AND ENDPOINTS
Table 2-1
Study Objectives and Endpoints
Objectives
Endpoints
Primary

To assess the bioequivalence of the 
nicotine 2 mg prototype mini lozenge 
with the 2 mg nicotine polacrilex mini 
lozenge (Nicorette Minis), in terms of 
nicotine AUC0-t, AUC0-inf , and Cmax.
AUC0-t – Area under the plasma 
concentration versus time curve from 
time zero to time t, where t is the time of 
the last measurable plasma concentration 
of nicotine, estimated.
AUC0-inf – Area under the plasma 
concentration versus time curve from 
time zero extrapolated to infinity
Cmax – The highest observed plasma 
nicotine concentration
Secondary
PK

To compare the nicotine 2 mg 
prototype mini lozenge to the 2 mg 
nicotine polacrilex mini lozenge 
(Nicorette Minis) in terms of tmax, t½, 
and Kel
tmax – time to maximum plasma 
concentration (Cmax)
t1/2 – plasma half-life
Kel – apparent elimination rate constant 
for plasma nicotine
Safety

To evaluate the safety of the nicotine 
2 mg prototype mini lozenge.
Safety assessments consists of 
monitoring and recording adverse events 
(AEs) and clinical safety laboratory test
This study will be considered successful if bioequivalence between the test and reference 
treatments conclude that the 90% confidence intervals for the ratio of the means of the 
primary pharmacokinetic parameters AUC0-t and AUC0-inf and Cmax of the nicotine profiles lie 
completely within the range 0.8-1.25.

STUDY DESIGN AND SUBJECT POPULATION

This study will be a single center, randomized, open label, single dose, two-way 
crossover in healthy smokers.  

Nicotine
207791
Final Clinical Protocol Amendment #2
GlaxoSmithKline Consumer Healthcare Confidential
Template Version Effective: 22-Jun-2017
Page 20 of 67

Enough healthy adult smokers will be screened to randomize at least 40 subjects to 
ensure 32 evaluable subjects complete the entire study. This will ensure approximately 
32 evaluable subjects per treatment arm.

Each subject will be treated with a single dose of the two study treatments in a 
randomized sequence, under fasting conditions.

Subjects will be confined in the study facility for approximately 60 hours during each 
study session (for 36 hours pre dosing and for 24 hours post dosing) during which 
pharmacokinetic (PK) blood samples will be obtained.

Subjects are to abstain from smoking during the confinement periods and be subject to 
random measurements of expired carbon monoxide (CO) to confirm abstinence.  The 
CO levels must be  10 ppm throughout the study session.

There will be at least 5-day and not more than 7-day clinical furlough period between 
treatment periods. For each treatment period, the clinical confinement period with 
restriction of smoking is at least 36 hours prior to dosing. The reported plasma t1/2 for 
nicotine is approximately 1 to 4 hours in a heterogeneous population such as the US. 
The 36 hour smoking restriction period prior to dosing will therefore minimize the 
residual nicotine amount from smoking during previous furlough.

Rationale for study design:  This will be an open label study.  Blinding is not 
considered essential as study measurements (blood nicotine concentrations) are 
biological.  A crossover design, using the same subjects to test each product, will be 
used to reduce variability.  

The blood sampling times have been chosen based on the information available 
particularly on nicotine absorption, as well as its elimination.

Smokers have been chosen as the population for this study as they are the population 
that the investigational product would target, if marketed.

Dose justification: This is a study to assess the bioequivalence of the test product to a 
commercial reference product.

of dosing until collection of the final pharmacokinetic sample of each study period. 

Subjects will abstain from the use of tobacco- or nicotine-containing products for 
36 hours prior to dosing and during confinement at the clinical site. 
4.4.3
Activity

Subjects will abstain from strenuous exercise (e.g., heavy lifting, weight training, 
calisthenics, aerobics) for at least 48 hours prior to each blood collection for clinical 
laboratory tests and throughout the entire study.  Walking at a normal pace will be 
permitted.
4.4.4
Contraception
All female subjects who are of childbearing potential and are sexually active and at risk for 
pregnancy must agree to use a highly effective method of contraception consistently and 
correctly for the duration of the active study period and for at least 5 days after the last dose of 
investigational product.  The investigator or his or her designee, in consultation with the 
subject, will confirm that the subject has selected an appropriate method of contraception for 
the individual subject from the permitted list of contraception methods (see below) and 
instruct the subject in its consistent and correct use.  Subjects need to affirm that they meet the 
criteria for the correct use of at least 1 of the selected methods of contraception.  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 the subject’s chart.  In addition, the investigator or his or her 
designee will instruct the subject to call immediately if the selected contraception method is 
discontinued.
Highly effective methods of contraception are those that, alone or in combination, result in a 
failure rate of less than 1% per year when used consistently and correctly (i.e., perfect use) 
and include the following:
1. Established use of oral, inserted, injected, transdermal, or implanted hormonal methods of 
contraception is allowed provided the subject plans to remain on the same treatment 
throughout the entire study and has been using that hormonal contraceptive for an 
adequate period of time to ensure effectiveness as deemed appropriate by the investigator.
2. Copper-containing intrauterine device (IUD). 
3. Male condom or female condom used WITH a spermicide (i.e., foam, gel, film, cream, or 
suppository).  For countries where spermicide is not available or condom plus spermicide 
is not accepted as highly effective contraception, this option is not appropriate.

4. Male sterilization with absence of sperm in the post-vasectomy ejaculate.
5. Bilateral tubal ligation / bilateral salpingectomy or bilateral tubal occlusive procedure 
(provided that occlusion has been confirmed in accordance with the device’s label).
6. Female who meets the criteria for non-childbearing potential as described below.  
Female subjects of non-childbearing potential must meet at least one of the following 
criteria:
a.
Achieved postmenopausal status, defined as follows: cessation of regular 
menses for at least 12 consecutive months with no alternative pathological or 
physiological cause; and have a serum follicle-stimulating hormone (FSH) 
level confirming the post-menopausal state;  
b. Have undergone a documented hysterectomy and/or bilateral oophorectomy.
All other female subjects (including females with tubal ligations) will be considered to be of 
childbearing potential.
4.5
Screen Failures
Screen failures are defined as subjects who consent to participate in the clinical study but are 
not subsequently randomized. In order 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 serious adverse events. 
Individuals who do not meet the criteria for participation in this study (screen failure) may not 
be re-screened.
4.6
Sponsor’s Qualified Medical Personnel
The contact information for the sponsor's appropriately qualified medical/dental personnel for 
the study is documented in the study contact list located in the supporting study 
documentation.
The contact number can be used by investigational staff if they are seeking advice on 
medical/dental questions or problems; however, it should be used only in the event that the 
established communication pathways between the investigational site and the study team are 
not available.  It is therefore intended to augment, but not replace, the established 
communication pathways between the investigational site and the study team for advice on 
medical/dental questions or problems that may arise during the study.  The contact number is 
not intended for use by the subject directly, and if a subject calls that number, he or she will 
be directed back to the investigational site.
To facilitate access to appropriately qualified medical/dental personnel on study-related 
medical/dental questions or problems, subjects are provided with a contact card.  The contact 
card contains, at a minimum, protocol identifiers, subject study numbers, contact information 
for the investigational site, and contact details in the event that the investigational site staff

according to the dosage and administration instruction. 
5.5
Administration
Following an overnight fast of least 10 hours, subjects will receive investigational product at 
approximately 0800 hours (plus or minus 2 hours). 
Subjects will keep the lozenge in their mouth, occasionally moving it side to side, allowing it 
to slowly dissolve completely, and try to minimize swallowing.
Subject will not chew the lozenge.
In order to standardize the conditions on pharmacokinetic sampling days, all subjects will be 
required to refrain from lying down (except when required for blood pressure, pulse rate, and 
ECG measurements), eating, and drinking beverages, with the exception of water, for the first 
4 hours after dosing. Water may be given after one hour post-dosing. 
5.5.1
Medication Errors
Medication 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 strength (other examples of concern may be added based on 
the investigational product administration, such as inadvertent exposure).  
Such medication errors occurring to a study participant are to be captured in the CRF.  In the 
event of medication dosing error, the sponsor should be notified immediately.

Nicotine

Medication errors are reportable irrespective of the presence of an associated AE/SAE, 
including:

Medication errors involving subject exposure to the investigational product;

Potential medication errors or uses outside of what is foreseen in the protocol that 
do or do not involve the participating subject.
Whether or not a medication error is accompanied by an AE, as determined by the 
investigator, the medication error and, if applicable, any associated adverse event(s) is 
captured on an adverse event (AE) CRF page.
5.6
Investigational Product Storage 
The investigator, or an approved representative, e.g., pharmacist, will ensure that all 
investigational products, including the comparator are stored in a secured area with controlled 
access under required storage conditions and in accordance with applicable regulatory 
requirements and 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 investigational 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 upon discovery.  
The site should actively pursue options for returning the product to the storage conditions as 
described in the labeling, as soon as possible.  Deviations from the storage requirements, 
including any actions taken, must be documented and reported to the Sponsor.  
Once an excursion is identified, the investigational product must be quarantined and not used 
until the Sponsor provides documentation of permission to use the investigational product.  It 
will not be considered a protocol deviation if the sponsor approves the use of the 
investigational product after the temperature excursion.  Use of the investigational product 
prior to sponsor approval will be considered a protocol deviation.  Specific details regarding 
information the site should report for each excursion will be provided to the site.

representative) should be notified and depending on the abnormality, the subject may be asked 
to remain at the clinical site until such abnormalities are deemed not clinically significant, or 
it is safe for outpatient follow-up.  If the subject is unable or unwilling to remain at the clinical 
site and/or when outpatient follow-up is deemed appropriate, the GSK CH medical monitor 
(or designated representative) should be so notified, and the investigator should make every 
effort to arrange follow-up evaluations at appropriate intervals to document the course of the 
abnormalities.
6.3
Subject Withdrawal
Subjects may withdraw from the study at any time at their own request, or they may be 
withdrawn at any time at the discretion of the investigator or sponsor for safety or, behavioral 
reasons, or the inability of the subject to comply with the protocol-required schedule of study 
visits or procedures at a given study site.  
The following circumstances require discontinuation of study treatment and/or premature 
subject withdrawal:

Protocol violation that may impact the outcome of the subject’s safety

Protocol violation that may interfere with the drug’s PK, including:
o
Vomiting shortly (within 30 minutes) after study drug administration
o
Swallowing the lozenge during the administration period
o
Any reported or suspected noncompliance of the smoking restriction during 
post dose PK observation period, e.g. CO > 10 ppm at any time during the 24 
post dose period (see Section 7.5 Expired Carbon Monoxide (CO) 
measurement for subject assessment)
o

Withdrawal of informed consent

Subject lost to follow-up 

Pregnancy

Death
If a subject is discontinued or prematurely withdraws from the study, reasons for 
discontinuation or withdrawal and associated date must be documented in the relevant 
section(s) of the CRF. 
If a subject does not return for a scheduled visit, every effort should be made to contact the 
subject.  The Investigator or site staff should attempt to contact the subject twice.  After two 
attempts, clinical site staff must send a registered letter.  If no response is received from the 

Nicotine
207791
Final Clinical Protocol Amendment #2
GlaxoSmithKline Consumer Healthcare Confidential
Template Version Effective: 22-Jun-2017
Page 38 of 67
subject, the subject will be considered lost to follow up.  All attempts to contact the subject 
and information received during contact attempts must be documented in the CRF.  In any 
circumstance, every effort should be made to document subject outcome, if possible.  The 
investigator should inquire about the reason for withdrawal, request that the subject return for 
a final visit, if applicable, and follow-up with the subject regarding any unresolved adverse 
events (AEs).
It may be appropriate for the subject to return to the clinical site for final safety assessments. 
Subjects should be questioned regarding their reason for withdrawal.  Assessments, at the 
investigator’s discretion, will include the following:

Brief physical examination;

Supine blood pressure respiratory rate, oral body temperature and pulse rate 
measurements.
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.

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 perform 
the test.  In these cases, the investigator must take all steps necessary to ensure the safety and 
well-being of the subject.  When a protocol-required test cannot be performed, the investigator 
will document the reason for the missed test 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 study team must be informed of these incidents in a timely manner.

Any remaining serum/plasma from samples collected for clinical safety labs at baseline and at 
all times post-dosing must be retained and stored for the duration of the study. 
7.2.2
Pregnancy Testing
For all female subjects, a serum pregnancy test, will be performed by the investigator or 
designee at Screening and Days -1 and 5-7.  Results will be obtained prior to dosing during 
each period.  
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.
7.2.3
Physical Examinations 
Physical examinations may be conducted by a physician, trained physician's assistant, or nurse 
practitioner as acceptable according to local regulation.  A full physical examination will 
include head, ears, eyes, nose, mouth, throat skin and lung examinations, lymph nodes, 
gastrointestinal, musculoskeletal, cardiovascular and neurological systems.  
The brief physical examination will be focused on general appearance, the respiratory and 
cardiovascular systems, as well as towards subject reported symptoms of adverse events if 
reported.
Any untoward findings identified on physical exams conducted after informed consent will be 
captured as an adverse event, if those findings meet the definition of an adverse event.
7.2.4
Height and Weight 
Height in centimeters (cm) and body weight in kilograms (kg) to the nearest 0.1 kilogram will 
be measured.
For measuring weight, a scale with appropriate range and resolution is 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.

7.2.5
Blood Pressure and Pulse Rate 
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.
Supine blood pressure will be measured with the subject’s arm supported at the level of the 
heart and recorded to the nearest mm Hg after approximately 5 minutes of rest.  The same arm 
(preferably the dominant arm) will be used throughout the study.  
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 
collection, blood pressure and pulse rate should be obtained prior to the nominal time of the 
blood collection.
7.2.6
Respiratory Rate
Respiratory rate will be measured after approximately 5 minutes rest in supine position by 
observing and counting the respirations of the subject for 30 seconds and multiplied by 2.  
When blood pressure is to be taken at the same time, respiration measurement will be done 
during the 5 minutes of rest and before blood pressure measurement.
7.2.7
Temperature
Temperature will be measured orally, and results recorded in the CRF.
No eating, drinking or smoking is allowed for 15 minutes prior to the measurement.
7.2.8
Electrocardiogram
A standard 12 lead ECG will be performed at Visit 1. Interpretation of the tracing must be 
made by a qualified physician or designee and documented on the ECG section of the CRF. 
Each ECG tracing should be labeled with the study number, subject initials, subject number, 
date, and kept in the source documents at the study site. Results or any clinically significant 
abnormalities should be reported in the CRF. Clinically significant abnormalities should also 
be recorded on the Adverse Event CRF. Clinically significant findings must be discussed with 
the GSK Clinical Project Lead (CPL) prior to enrolling the subject in the study.
Subjects should be in a quiet environment and not speak during the resting period or 
measurement.  Generally, ECGs should not be collected within 3 hours after food or beverage 
consumption.

7.3
Pharmacokinetics (PK)
Twenty-two (22) blood samples will be collected for pharmacokinetic analysis:  at baseline 
(-45 minutes, -30 minutes and -15 minutes prior to dosing), and at 5, 10, 20, 30, 40, 50, 60, 75 
and 90 minutes and at 2, 3, 4, 6, 8 10, 14, 16, 20 and 24 hours following study drug 
administration. A blood volume of 6 mL per time point, will be collected via direct 
venipuncture. If the blood volume is unable to be collected by venipuncture, due to failure or 
inability draw blood, then catheter will be used for collection. Study drug administration is 
defined as the placement of the nicotine lozenge in the mouth of the subject.
A total of approximately 296 mL blood will be taken during the trial, including 264 mL for 
PK samples and 32 mL for safety laboratory tests.
7.3.1
PK samples and safety laboratory tests
During all study periods, blood volumes (6 mL) to provide a minimum of 1.5 mL plasma for 
pharmacokinetic analysis will be collected into appropriately labeled lavender top tubes 
containing K2EDTA at times specified in the Study Procedures section of the protocol.  The 
plasma will be split into 2 transfer tubes.
The actual times may change but the number of samples will remain the same.  All efforts will 
be made to obtain the pharmacokinetic samples at the exact nominal time relative to dosing.  
However, samples obtained within 3 minutes will not be captured as a protocol deviation, as 
long as the exact time of the sample collection is noted on the source document and data 
collection tool (e.g., CRF).
Samples will be analyzed using a validated analytical method in compliance with applicable 
Celerion standard operating procedures.
The PK samples must be processed and shipped as indicated to maintain sample integrity.  
Any deviations from the PK processing steps, including any actions taken, must be 
documented and reported to the sponsor.  On a case-by-case basis, the sponsor may make a 
determination as to whether sample integrity has been compromised.  Any sample deemed 
outside of established stability, or of questionable integrity, will be considered a protocol 
deviation.
Samples will be stored for a period of up to 5 years, until regulatory submissions are 
completed, or upon the request of GSK, at which all samples will be destroyed.   The 
individual subject samples may also be destroyed upon request of the subject. The samples 
will be stored according to Celerion’s standard operating procedures.  There will be no use of 
these samples for further research.

Blood Volume
The total blood sampling volume for each subject in this study is approximately 296 mL.  The 
table below reflects approximate sample volumes needed for each measured endpoint.  The 
actual collection times of blood sampling may change, but the total blood volume collected 
will not increase.  Additional blood samples may be taken for safety assessments at the

Expired Carbon Monoxide (CO) measurement
Using a calibrated Bedfont Smokerlyzer®, the investigator or designee will perform six (6) 
scheduled CO measurements, one upon check-in at Baseline, one immediately before 
randomization in Period 1, one immediately prior to dose administration in Period 2, and 
another immediately after the last PK sample has been collected at each study session.  
Additionally, the investigator or designee will conduct at least four (4) random CO 
measurements during each study period to verify smoking abstinence.  The timing of the 
random CO measurements will be decided by the investigator or designee.  For each CO 
measurement, subjects will be instructed to inhale deeply, hold their breath for 15 seconds and 
produce a non-forced, steady 15 second exhalation through the disposable mouthpiece of the 
inflow valve of the CO monitor.
Prior to randomization: If the CO value is not within limits just prior to randomization, an 
additional CO measurement can be repeated after 2 hours if the value is ≤15ppm. If CO value 
remains out of limit, then subject will not be randomized.

During study: If a CO value is not within limits during the study, an additional CO 
measurement may be taken to confirm the results. 

If second value is still not within the limits, subject will be discontinued from study

If second value is within limits, state reason for repeated measure (e.g. incorrect use of 
CO monitor). Repeat measurement again in 30 minutes to confirm. If the third 
measurement is within limits, subject may continue with study. If third measurement is 
not within limits, then subject will be discontinued from study.
All values, including time of measurement and reason for re-measurement will be recorded in 
the CRF.

ADVERSE EVENT 
8.1
Definitions of Adverse Events and Serious Adverse Events
8.1.1
Adverse Event
An AE is any untoward medical occurrence in a clinical study participant, temporally 
associated with the use of an investigational or washout product or medical device, whether or 
not considered related to the investigational or washout product or medical device.
NOTE: An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the 
use of a study treatment.
Events Meeting the AE Definition:  

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or 
other safety assessments (eg, ECG, radiological scans, vital sign measurements), 
including those that worsen from baseline, considered clinically significant in the 
medical and scientific judgment of the investigator (ie, not related to progression of 
underlying disease).

Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition.

New conditions detected or diagnosed after study treatment administration even 
though it may have been present before the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction.

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
treatment or a concomitant medication. Overdose per se will not be reported as an 
AE/SAE unless it is an intentional overdose taken with possible suicidal/self-harming 
intent. Such overdoses should be reported regardless of sequelae.
Events NOT meeting the AE definition:

Template Version Effective: 22-Jun-2017
Page 45 of 67

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. 
8.1.2
Serious Adverse Event
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 participant 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 participant 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 AE. 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 (eg, 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 participant 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.
8.2
Reporting Period
8.2.1
Adverse Event
AEs (serious and nonserious) will be collected from the signing of the ICF and until 5 days 
following last administration of the investigational product. For studies that have a run-in 
period or washout period, adverse events will be collected from the time the run-in or washout 
period begins. 
Medical occurrences that begin before obtaining informed consent will be recorded on the 
Medical History/Current Medical Conditions section of the case report form (CRF).
8.2.2
Serious Adverse Event
SAEs assessed as related to study participation (e.g., investigational product, protocol 
mandated procedures, invasive tests, or change in existing therapy) or related to a GSK 
concomitant medication will be recorded from the time a subject provides informed consent, 
which is obtained prior to the subject’s participation in the study, i.e., prior to undergoing any 
study-related procedure and/or receiving investigational product and until 5 days following 
last administration of the investigational product.
SAEs assessed as not related to study participation (e.g., investigational product, protocol 
mandated procedures, invasive tests, or change in existing therapy) or not related to a GSK 
concomitant medication will be recorded from the time the subject has taken at least 1 dose of 
investigational product and until 5 days following last administration of the investigational 
product.

8.3
Reporting Procedures
The investigator and any designees are responsible for detecting, documenting and reporting 
events that meet the definition of an AE or SAE and remain responsible for following up on 
AEs that are serious, considered related to the study treatment or the study, or that caused the 
participant to discontinue the study. 
The investigator 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 SAEs.  If an SAE occurs, 
expedited reporting will follow local and international regulations, as appropriate.
When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (eg, hospital progress notes, laboratory, and diagnostics reports) related to the 
event.
The investigator or site staff will then record all relevant information regarding an AE/SAE in 
the CRF.
It is not acceptable for the investigator to send photocopies of the participant’s medical 
records to GSK in lieu of completion of the GSK /AE/SAE CRF page.
There may be instances when copies of medical records for certain cases are requested by 
GSK.  In this instance, all subject identifiers, with the exception of the subject number, will be 
blinded on the copies of the medical records prior to submission to GSK.
The investigator will attempt to establish a diagnosis of the event based on signs, symptoms, 
and/or other clinical information.  In such cases, the diagnosis will be documented as the 
AE/SAE and not the individual signs/symptoms. Clinical AEs will be described by diagnosis 
and not by symptoms when possible (e.g., upper respiratory tract infection, seasonal allergy, 
etc. instead of runny nose).
Medical conditions reported prior to the time period for reporting AEs/SAEs should be 
recorded as part of the subject’s medical history.
AEs elicited by the investigator in a standard manner at the study visits should also be 
recorded in the AE section of the CRF. Care will be taken not to introduce bias when 
detecting AE and/or SAE. Open-ended and non-leading verbal questioning of the participant 
is the preferred method to inquire about AE occurrence.
8.3.1
Adverse Event
All AEs will be reported on the AE page(s) 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 

Nicotine
207791
Final Clinical Protocol Amendment #2
GlaxoSmithKline Consumer Healthcare Confidential
Template Version Effective: 22-Jun-2017
Page 48 of 67
CRF.  Where the same data are collected, the forms must be completed in a consistent 
manner.  For example, the same AE term should be used on both forms.  AE should be 
reported using concise medical terminology on the CRF as well as on the form for collection 
of SAE information.
8.3.2
Serious Adverse Event
A paper copy of the SAE form provided in the investigator study master file should be 
completed as fully as possible. 
It is essential to enter the following information: 

Protocol and subject identifiers

Subject’s demography

Description of events, with diagnosis if available

Investigator opinion of relationship to study product 

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

Action taken on study product

Outcome if known
Celerion will email the SAE form to the Case Management Group, Global Clinical Safety and 
Pharmacovigilance at GSK (
), with copy to the appropriate GSK CH 
Study Manager as soon as possible, but not later than 1 business day after study site 
personnel learn of the event. The GSK CH Study Manager will be responsible for forwarding 
the SAE form to other GSK CH personnel as appropriate.

8.3.3
Sponsor’s Reporting Requirements to Regulatory Authorities and 
Ethics Committees
GSK has a legal responsibility to notify, as appropriate, the local regulatory authority and 
other regulatory authorities about the safety of a product under clinical investigation.  Prompt 
notification of SAEs by the investigator to GSK is essential so that legal obligations and 
ethical responsibilities towards the safety of subjects are met.
GSK will comply with country specific regulatory requirements relating to safety reporting to 
the regulatory authority, IRB/EC and investigators.
Investigator safety reports must be prepared for suspected unexpected serious adverse 
reactions (SUSAR) according to local regulatory requirements and sponsor policy and 
forwarded to investigators as necessary.
An investigator who receives an investigator safety report describing a SAE or other specific 
safety information eg, summary or listing of SAE, from the sponsor will review and then file 
it along with the Investigator’s Brochure and will notify the IRB/IEC, if appropriate according 
to local requirements.
8.4
Evaluating Adverse Events and Serious Adverse Events
8.4.1
Severity Assessment
The investigator or designee will make an assessment of severity for each AE and SAE 
reported during the study and will assign it to one of the following categories:

Mild:  An event that is easily tolerated by the subject, causing minimal discomfort and 
not interfering with everyday activities.

Moderate:  An event that is sufficiently discomforting to interfere with normal 
everyday activities

Severe:  An event that prevents normal everyday activities. 
Note: An AE that is assessed as severe will not be confused with an SAE. Severity is a 
category utilized for rating the intensity of an event; and both AEs and SAEs can be assessed 
as severe. For example, a headache may be severe (interferes significantly with the subject's 
usual function) but would not be classified as serious unless it met one of the criteria for 
SAEs, listed above. 
8.4.2
Causality Assessment
The causality assessment is one of the criteria used when determining regulatory reporting 
requirements. For each AE/SAE, the investigator must document in the medical notes that 
he/she has reviewed the AE/SAE and has provided an assessment of causality. The 

Nicotine
207791
Final Clinical Protocol Amendment #2
GlaxoSmithKline Consumer Healthcare Confidential
Template Version Effective: 22-Jun-2017
Page 50 of 67
investigator’s assessment of causality must be provided for all AEs (serious and non-serious); 
the investigator must record the causal relationship in the CRF, as appropriate, and report such 
an assessment in accordance with the SAE reporting requirements if applicable.  
A "reasonable possibility" of a relationship conveys that there are facts, evidence, and/or 
arguments to suggest a causal relationship, rather than a relationship cannot be ruled out. 
Generally, the facts (evidence) or arguments to suggest a causal relationship should be 
provided.
The investigator will use clinical judgment to determine the relationship and will also consult 
the Investigator Brochure (IB), Safety Statement and/or Product Information, for marketed 
products, in the determination of his/her assessment.  Alternative causes, such as underlying 
disease(s), concomitant therapy, other risk factors, and the temporal relationship of the event 
to the study product will be considered and investigated.
There may be situations when an SAE has occurred and the investigator has minimal 
information to include in the initial report to GSK.  However, it is very important that the 
investigator always make an assessment of causality for every event prior to the initial 
transmission of the SAE data to GSK. The investigator may change his/her opinion of 
causality in light of follow-up information and send an SAE follow-up report with the updated 
causality assessment. 
8.5
Withdrawal Due to an Adverse Event and Serious Adverse 
Events
Withdrawal due to AEs should be distinguished from withdrawal due to other causes, 
according to the definition of AE noted earlier, and recorded on the appropriate AE CRF page. 
When a subject withdraws because of an SAE, the SAE must be reported in accordance with 
the reporting requirements defined below.
8.6
Pregnancy
8.6.1
Time Period for Collecting Pregnancy Information
Pregnancy information will be collected on all pregnancies reported following administration 
of any investigational product or washout product and until 48 hours after the last dose.
8.6.2
Action to be Taken if Pregnancy Occurs
The investigator will collect pregnancy information on any subject who becomes pregnant 
while participating in the study after administration of the investigational product. The 
investigator will record pregnancy information on the appropriate form and submit it to the 
Case Management Group, Global Clinical Safety and Pharmacovigilance group mailbox at 
GSK within 24 hours of learning of the subject becoming pregnant. The subject will be

followed to determine the outcome of the pregnancy. Information on the status of the mother 
and infant / neonate (including concomitant medications taken by the mother during the 
pregnancy) will be forwarded to the Case Management Group, Global Clinical Safety and 
Pharmacovigilance group mailbox at GSK. Generally, follow-up will be no longer than 6 to 8 
weeks following the estimated delivery date. Any termination of the pregnancy will be 
reported. 
While pregnancy itself is not considered to be an AE, abnormal pregnancy outcomes (eg, 
spontaneous abortion, fetal death, stillbirth, congenital anomalies, ectopic pregnancy) are 
considered to be and should be recorded as an SAE.
Any female participant who becomes pregnant while participating will discontinue study 
treatment or be withdrawn from the study. 
Like with SAE and Incident Forms, Celerion will email the pregnancy form to the Case 
Management Group, Global Clinical Safety and Pharmacovigilance group mailbox at GSK 
(
) with copy to the appropriate GSK CH Study Manager. 
8.7
Follow-up of Adverse Events and Serious Adverse Events
After the initial report, the investigator is required to proactively follow up with each subject 
and provide further information on the subject’s condition.
All AEs/SAEs will be followed until resolution, until the condition stabilizes, until the event 
is otherwise explained, or until the subject is lost to follow-up.  
The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as may be indicated or as requested by GSK to elucidate as 
fully as possible the nature and/or causality of the AE or SAE. This may include additional 
laboratory tests or investigations, histopathological examinations, or consultation with other 
health care professionals.
New or updated information will be recorded in the originally completed CRF.
The investigator will submit any updated SAE data to GSK within 24 hours of receipt of the 
information.
Investigators are not obliged to actively seek AEs or SAEs in former subjects.  However, if 
the investigator learns of any SAE, including the death, at any time after a subject has been 
discharged from the study, and considers the event reasonably related to the investigational 
product or study participation, the investigator will promptly notify GSK by emailing the 
information to the GSK CH Clinical Operations Safety Reporting email box (
). The GSK CH Study Manager or designee will be responsible for 
forwarding the information to the Case Management Group, Global Clinical Safety and 
Pharmacovigilance group mailbox at GSK (
).
The investigator will submit any updated SAE data to GSK within the designated reporting 
time frames.

DATA MANAGEMENT
As used in this protocol, the term CRF should be understood to refer to either a paper form or 
an electronic data record or both, depending on the data collection method used in this study. 
For this study subject data will be entered into a Contract Research Organization (CRO) 
electronic CRF, using a validated data system.
9.1
Source Documents/ Data
The source documents (e.g., hospital records, clinical and office charts, laboratory notes, 
memoranda, subjects’ diaries or evaluation checklists, pharmacy dispensing records, recorded 
data from automated instruments, microfiches, photographic negatives, microfilm or magnetic 
media, x-rays, subject files and records kept at the pharmacy, at the laboratory and at the 
medico-technical departments involved in the clinical study) which contain the source of data 
recorded in the CRF should be specified in Section 6 .  The CRF can be used as a source 
document at the discretion of data management.
Each subject will be assigned and identified by a unique Number. Any reference made to an 
individual subject within the study must be done using the unique Screening Number.
9.2
Case Report Form
A CRF is a printed, optical, or electronic document designed to record all of the protocol 
required information to be reported to the sponsor on each trial subject.
For each subject who has given informed consent/assent and has been screened, CRF must be 
completed and signed by the Principal Investigator (or authorized designee) to certify that the 
data are complete and correct.  
Management of clinical data will be performed in accordance with applicable GSK CH 
standards and data cleaning procedures to ensure the integrity of the data e.g. removing errors 
and inconsistencies in the data. 
In order to protect the privacy of subjects, no Personally Identifiable Information (PII) 
(including the subject's name or initials or full birth date) is to be recorded in the CRF or as 
part of the query text.
All CRF pages should be completed during a subject assessment when the CRF has been 
designated as the source.  Data that is sourced elsewhere should be entered into the CRF in an 
agreed upon timeframe between the Investigator and Sponsor.  
GSK CH will obtain and retain all CRFs and associated study data at the completion of the 
study. 
9.3
Data Handling
Documentation of all data management activities should allow step-by-step retrospective 
assessment of data quality and study performance.

Page 53 of 67
Any changes or corrections to data will be performed in the Electronic Data Capture (EDC) 
System, and it will include rationale for changes. The EDC system has an audit trail, which 
will provide a complete record of the changes and corrections endorsed by the Investigator.
Adverse events will be coded using MedDRA (Medical Dictionary for Regulatory Activities) 
and concomitant medications terms using an internal validated medication dictionary, 
GSKDrug.  
9.3.1
Queries
Programmed edit checks will be generated automatically, as the data is being entered into the 
system. Data Management will also run reports and listings on the CRF data, in addition to the 
queries already programmed and generated by the system, to raise manual queries as needed 
for site clarification or correction. The Clinical Dictionary Development and Management 
Group will raise queries as needed on safety data to code the terms (Adverse Events and 
Drugs) appropriately. 
The study monitor at the study site will review the CRFs in accordance with the monitoring 
plan, and 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 correction.
9.4
Processing Patient Reported Outcomes
There will be no Patient reported outcome (PRO) data for this study.  
9.5
External Data 
External Data are subject data obtained externally to the CRF. These data are generated from 
laboratory instruments, computers or other sources and then transcribed into a file and format 
agreed upon by GSK CH to identify the subject and time point referenced in the CRF and/or 
protocol. 
An agreed upon quality control process is performed against the transcribed data to the source 
to ensure the accuracy of the transcription. The transcribed data is transmitted in an agreed 
upon format to GSK CH. 
Reconciliation will be performed between the transcribed data and the clinical database to 
ensure subject and time point referenced in the Clinical Database match before Clinical 
Database Freeze (locking of the database) can occur.

STATISTICAL CONSIDERATIONS AND DATA ANALYSES
10.1
Sample Size Determination
Enough healthy adult smokers will be screened to randomize forty (40) healthy adult smokers, 
to ensure that thirty-two (32) complete the entire study assuming a 20% dropout and non-
evaluable rate. The highest intra-subject CV observed in previous studies was 23%. The 
protocols that were used to select the highest CV for the sample size calculation are: 
 
 
 
 and S6491365 (2mg nicotine polacrilex mini cherry 
lozenge v.s 2mg nicotine polacrilex mini mint lozenge: Cmax =13.7%; AUC0-t =10%). A total 
of thirty-two (32) evaluable subjects will achieve a 90% power at 5% significance level. The 
true ratio that was used in the sample size calculation was 1.05.
10.2
Statistical Methods and Analytical Plan
Additional details of the proposed statistical analysis will be documented in the statistical 
analysis plan (SAP), which will be written following finalization of the protocol and prior to 
the database lock and analysis. SAP creation and statistical analysis will be performed by 
Celerion.
Pharmacokinetic variables will be calculated by Celerion.
All concentration and PK data will be listed. This includes any data for subjects who are not 
included in the analysis.
10.2.1
Demographic and Baseline Characteristics
Baseline data, relevant screening data, and demographic characteristics will be summarized 
for all randomized subjects.
10.2.2
Treatments (study drug, rescue medication, other concomitant 
therapies, compliance)
The number of subjects exposed to each treatment will be tabulated for the safety population. 
Treatment deviations for individual subjects will be listed and summarized. Cases of partial 
exposure, including swallowing or premature expulsion of the treatment and subjects with 
baseline > 5% of the Cmax will also be summarized. For predose-adjusted data, baseline 
nicotine concentration is defined as the time zero concentration estimated by the log-linear 
regression according to a mono-compartmental deconvolution of the three pre-dose time 
points, i.e. – 45 minutes, - 30 minutes and -15 minutes prior to dosing. Other medications and 
other concomitant non-drug therapies will be listed for the safety population.

Primary Analysis
10.2.3.1
Criteria for assessing bioequivalency
The bioequivalence between the test and reference treatments will be concluded if the 90% 
confidence intervals for the ratio of the means of the primary pharmacokinetic parameters 
AUC0-t and AUC0-inf and Cmax of the nicotine profiles lie completely within the range 0.8-1.25.
10.2.3.2
Pharmacokinetics Analysis
Variables:
For each study product, the following pharmacokinetic parameters will be estimated: 
AUC0-t: Area under the plasma concentration versus time curve from time zero to time t, 
where t is the time of the last measurable plasma concentration of nicotine, 
estimated.
AUC0-inf: Area under the plasma concentration versus time curve calculated from time zero to 
infinity.
Cmax: The highest observed plasma nicotine concentration.
PK evaluation:
The primary objective will be evaluated based on the following comparison: 
The nicotine 2 mg prototype mini lozenge (Test) versus the 2 mg nicotine polacrilex mini 
lozenge (Nicorette Mini, Reference), in terms of nicotine AUC0-t, AUC0-inf and Cmax.
The primary statistical analyses will be done based on PK analysis set, PKAS1 (see section 
10.2.7 for definition). An additional analysis (for pre-dose adjusted data only) will be 
performed on PK analysis set, PKAS2. Safety population will be used for individual plasma 
concentration listings and figures.  
Individual plasma concentrations will be listed and summarized descriptively at each time 
point; the concentration vs. time profile will be graphed by formulation for individual 
subjects and for the mean on both original and logarithmic scales with Safety population.
All PK parameters (except Kel, t½ and tmax) will be summarized for each treatment by 
descriptive statistics (N, arithmetic mean, standard deviation, geometric mean, coefficient of 
variation, median, minimum, and maximum). A listing containing individual and summary 
statistics for each PK parameter will be provided.  A similar listing will be provided for log 
and linear blood concentrations over time containing individual values and summary statistics 
for each time point.

BE of the test product with reference will be assessed by pairwise comparison of the PK 
parameters (Cmax, AUC0-t, and AUC0-inf) for the nicotine concentration profiles based on the 
PK analysis set, PKAS1. 
A linear mixed effects model will be fit to the log-transformed PK variables (AUC0-t, AUC0-inf 
and Cmax), as the dependent variable, and treatment, and period as fixed effects. Subject nested 
within sequence will be a random effect. For each pairwise comparison, only the data from 
the two, corresponding treatments will be included in the model. The presence of a 
statistically significant sequence effect will be noted and its implications will be discussed. 
Least squares estimates of treatment effects will be calculated and a 90% confidence interval 
(CI) for the treatment difference will be computed. The treatment difference and its CI will be 
exponentiated to obtain the ratio of the geometric means between the test and reference 
products and its CI. Bioequivalence will be determined if the 90% confidence interval for the 
treatment geometric mean ratio lies completely within the range 0.80 – 1.25.  
10.2.3.3
Correction for non-zero baseline for an additional analysis.
The pre-dose nicotine concentration will be estimated based on a log-linear regression 
according to a mono-compartmental deconvolution of the three pre-dose time points, i.e. -45 
minutes, -30 minutes and -15 minutes prior to dosing. Subsequent plasma concentrations will 
be corrected by subtracting an estimate of the residual baseline plasma nicotine concentration 
computed with log-linear regression according to a mono-compartmental deconvolution as 
follows:
RCt,ij = Cpre-dose,ij *exp (-Kelij*t)
where
RCt = estimated residual concentration (nicotine in plasma) at time t,
Cpre-dose = plasma nicotine concentration before dosing,
Kel = slope calculated by log-linear regression using the elimination portion of the PK profile 
for the associated treatment.
t = time (h) between the considered blood sampling and the time of pre-dose sampling.
i = treatment (Test or Reference)
j = patient
The plasma concentration at time t, observed after dosing and corrected for baseline, will be 
equivalent to the following:
Ct,ij(R)=Ct(O)-RCt
Where:
Ct(R) = baseline corrected nicotine concentration Ct(O) = observed nicotine concentration 
detected in patient plasma 
This adjustment will only be applied in cases where the pre-dose value is greater than zero.

Secondary Analysis
The PK analysis set, PKAS1 will be used for the secondary analysis. 
For each study product, the following pharmacokinetic parameters will be estimated: 
tmax
time to maximum plasma nicotine concentration;
t1/2
apparent elimination half-life;
Kel
apparent elimination rate constant for plasma nicotine.
The parameters Kel and t½ and tmax be summarized (mean, median, Q1, Q3, minimum, 
maximum, standard deviation, and coefficient of variation) for each study treatment. A 
nonparametric analysis will be performed to compare study treatments using the Wilcoxon 
Signed Rank Test. Median difference, 95% confidence interval and p-value will also be 
presented.
Additional PK parameters or statistical analyses may be performed as appropriate.
10.2.5
Safety Analysis
Safety variables will be summarized for the safety population.
Adverse Event:
Treatment Emergent adverse events, i.e. AEs that are emergent or that worsen after the first 
mini lozenge administration, will be summarized by presenting, for each treatment, the 
number and percentage of subjects having any AE, any AE in each MedDRA System Organ 
Class (SOC) and having each individual AE. The subset of AEs suspected of a relationship to 
study drug will be presented similarly. All treatment-emergent AEs will also be tabulated by 
severity. Any other information collected (e.g. action taken, duration, outcome) will be listed. 
Each AE will be attributed to the treatment taken most recently before the onset of the AE.
Vital signs:
Vital signs including temperature will be summarized by time-point and treatment.  Summary 
statistics will include mean, standard deviation, minimum, median, and maximum. No 
inferential statistics will be presented. Data will be listed with abnormal values flagged.
Physical examination
Physical Examination data will be listed with abnormal values flagged.
Safety Laboratory:
Safety Laboratory data will be listed with abnormal values flagged.


CO monitoring
10.2.7
Definition of Analysis Populations
The safety population is defined as all randomized subjects who receive at least one dose of 
study medication.
The PK population is defined as all randomized subjects who completed both periods, and 
who had no major protocol deviations concerning pharmacokinetics. 
The following 2 PK analysis sets are defined to address the PK objectives and further PK 
considerations within this study:

PKAS1 includes all subjects of the PK population. Subjects with baseline nicotine 
concentration > 5% of the individual Cmax for either period will be excluded. This analysis 
set will be used in PK summaries, the primary analysis, and the secondary analysis..

PKAS2 includes all subjects of the PK population, for which the relevant predose-adjusted 
PK parameters (at least one AUC or Cmax) can be derived. This analysis set will be used 
in PK summaries and an additional analysis. 
10.2.8
Exclusion of Data from Analysis 
Subjects who deviate from the protocol will be identified and excluded from the 
pharmacokinetic analyses as agreed by the biostatistician and medical director or designee. 
For the primary analysis of PK parameters, subjects with baseline concentrations > 5% of Cmax 
will be excluded (from PKAS1).
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.
10.2.9
Handling of Dropouts and Missing Data 
All existing data for subjects who are dropouts from the study will be included in the 
pharmacokinetic statistical analysis.

If any concentration data is missing or deviates from the planned time of collection, then the 
pharmacokineticist may calculate the PK parameters using the available data. 
Missing values of Kel can be estimated from the subject’s mean Kel value from the other 
treatments. If a Kel value cannot be calculated from the other treatments, then the Kel will be 
obtained from the treatment mean value for subjects with non-missing values of Kel in the 
period in which it is not available. This estimated Kel can be used to calculate other Kel 
dependent variables. This Kel value derivation is only applied for pre-dose concentration 
adjustments.
For nicotine concentration:

BLOQ values obtained before Cmax will be imputed as zero.

BLOQ values obtained after Cmax will be imputed as “Not detectable” (ND), which 
will be shown as missing (explanations will be specified in the footnote of TFLs).

STUDY GOVERNANCE CONSIDERATIONS
11.1
Quality Control 
In accordance with applicable regulations including GCP, and GSK procedures, GSK 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 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 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.

11.2
Quality Assurance
To ensure compliance with GCP and all applicable regulatory requirements, GSK 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.
11.3
Regulatory and Ethical Considerations
11.3.1
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.
11.3.2
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), 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.
11.3.3
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 in order to de-identify study subjects. The use of 
initials should be avoided.  
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. 
The investigator, or a person designated by the investigator, will obtain written informed 
consent from each subject before any study-specific activity is performed.  The investigator 
will retain the original of each subject's signed informed consent document.
11.3.4
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.

11.3.5
Reporting of Safety Issues and Serious Breaches of the Protocol or 
ICH GCP 
Within a 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.
11.4
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 processes.
11.5
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 site or other mutually-agreeable 
location.
GSK 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 Policy.
A manuscript will be progressed for publication in the scientific literature if the results 
provide important scientific or medical knowledge.
11.6
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.

Nicotine
207791
Final Clinical Protocol Amendment #2
GlaxoSmithKline Consumer Healthcare Confidential
Template Version Effective: 22-Jun-2017
Page 63 of 67
The records (study/ site master file) must be maintained to allow easy and timely retrieval, 
when needed (e.g., for a GSK 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 25 years from the issue of the final Clinical Study Report 
(CSR)/ 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 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 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.
11.7
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 investigational product safety problems, or at the 
discretion of GSK CH.  In addition, GSK CH retains the right to discontinue development of 
nicotine prototype mini lozenge at any time. 
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.
11.8
Definition of Study End/ End of Study 
Study End (SE) date is defined as the date of the last subject visit of the last subject to 
complete the study (LSLV). 
The End of Study (EOS) is the date of the last event/testing/reading related to the primary and 
secondary endpoints, to be achieve no later than 8 months after SE.
