SYNOPSIS  . 
NAME OF COMPANY: Achieve Life Sciences, Inc 
NAME OF INVESTIGATIONAL MEDICINAL PRODUCT (CYTISINE):  
Cytisine 1.5 mg film-coated tablet 
TITLE OF STUDY: A phase 1 open label, randomized, two-way crossover study in healthy 
smokers to investigate the effect of food on the bioavailability of cytisine in a new formulation 
PRINCIPAL INVESTIGATOR: 
 
STUDY CENTRE: Simbec Research Ltd (Simbec) 
     Merthyr Tydfil, CF48 4DR, UK 
CLINICAL PHASE: I 
OBJECTIVES: 
Primary:  
• To compare the bioavailability (Cmax and AUC0-∞) of cytisine in healthy smokers 
under fed and fasted conditions, following administration of 3 mg cytisine (2 x 
1.5 mg cytisine tablets). 
• To assess the extent of renal elimination of cytisine via measurement of urinary 
concentrations, following administration of 3 mg cytisine (2 x 1.5 mg cytisine 
tablets). 
Secondary:  
• To compare the AUC0-t, T½ and Tmax of cytisine in subjects under fed and fasted 
conditions, following administration of 3 mg cytisine (2 x 1.5 mg cytisine tablets). 
• To assess the safety and tolerability of cytisine in a new formulation at the 3 mg 
dose level under fed and fasted conditions. 
 
METHODOLOGY:  
This will be an open-label, randomised, 2- treatment period, single-dose crossover study to 
determine the comparative bioavailability and renal elimination of cytisine following single-
dose administration in healthy smokers under fed and fasted conditions.   
The study will be comprised of a pre-study screen, followed by 2 treatment periods (1 and 2) 
and a post-study follow-up.   
Screening (Day -28 to Day -1): Screening assessments will be carried out within 28 days 
before first administration of cytisine.   
Baseline (Day 0): Baseline assessments will be carried out one day before the first 
administration of cytisine.   
Treatment Periods (Day 1 to Day 5):  Eligible subjects will receive a single-dose of cytisine 
under fed and fasted conditions during 2 treatment periods over a 5-day time frame. Each 
treatment period will be approximately 2 days’ duration in which blood and urine samples will 
be collected over a 48 h period post cytisine dosing. This will require a total of 5 overnight 
stays in the Clinical Unit. The study will begin the afternoon before the first dosing on Day 0 
and the treatment period will start with the first dose on Day 1 and continue until 48 hours (h) 
after the second dosing on Day 5.   
Subjects will arrive at the Clinical Unit on Day 0 and will undergo an overnight fast of at least

Cytisine 
 CONFIDENTIAL 
 
 
4 
10 h prior to first dosing on Day 1. Randomisation will occur on the morning of Day 1, Period 
1, and cytisine will be administered under fasted (after an overnight fast of at least 10 h) or fed 
(after a high fat breakfast) conditions.  Subjects will complete all 48 h postdose assessments 
prior to starting Period 2 and the second dosing on Day 3.   
Plasma and urine samples will be collected predose and up to 48 h postdose during each period 
(18 plasma samples and 11 urine samples per period) for the measurement of plasma and 
urinary cytisine concentrations. The 2 periods allow 48 hours between dose administrations. 
Safety will also be evaluated at specified times.   
Post Study: Post study telephone follow-up will be conducted 6 to 8 days after the second dose 
of cytisine. 
NUMBER OF SUBJECTS: 12 subjects will be randomised/enrolled to complete the study. 
MAIN INCLUSION CRITERIA: 
Healthy smokers (males or females who are non-pregnant/non-lactating) aged 18 - 55 years, 
with no allergy or sensitivity to cytisine or any of its excipients, who unless surgically sterile, 
abstaining from sexual intercourse or of non-child bearing potential, are willing to use an 
effective method of contraception from the first dose and for 3 months after the last dose of 
cytisine. 
CYTISINE ADMINISTRATION: 
Each subject will receive cytisine over 2 treatment periods under fed and fasted conditions in 
accordance with the randomisation schedule:   
Schedule A (6 subjects):  
• Period 1: Cytisine (2 x 1.5 mg tablets) will be administered 30 minutes after the start of 
a high fat breakfast (fed state). 
• Period 2: Cytisine (2 x 1.5 mg tablets) will be administered after an overnight fast of at 
least 10 hours (fasting state). 
Schedule B (6 subjects):  
• Period 1: Cytisine (2 x 1.5 mg tablets) will be administered after an overnight fast of at 
least 10 hours (fasting state). 
• Period 2: Cytisine (2 x 1.5 mg tablets) will be administered 30 minutes after the start of 
a high fat breakfast (fed state). 
240 mL water will be given with the dose. 
CRITERIA FOR EVALUATION: 
Study Endpoints:   
Plasma: The following PK endpoints will be derived from plasma cytisine concentration versus 
time data following administration of 3 mg cytisine (2 x 1.5 mg) under fed and fasted conditions: 
Maximum concentration (Cmax), time to Cmax (Tmax), elimination rate constant (kel), terminal 
elimination halflife (T1/2), area under the concentration versus time curve (AUC) from time of 
dosing to last measurable concentration (AUC0t), AUC extrapolated to infinity (AUC0inf) and 
AUC% extrapolated (residual area). 
Urine: Amount excreted in urine over time (Ae) and percent of cytisine excreted in urine 
(Ae%) will be calculated. 
Safety Endpoints: AEs, vital signs (supine systolic/diastolic pressure, pulse and oral 
temperature), 12 lead ECG, laboratory safety (haematology, biochemistry and urinalysis).

STATISTICAL METHODS:   
All statistical analysis will be performed using SAS® version 9.3. 
Demographic and Background Data: All demographic and background data will be listed. 
Demographic data will be summarised  (age, height, weight, BMI and race) by gender and 
overall. Subject disposition and analysis sets (safety, PK) will also be listed and summarised by 
frequency. 
Urine Excretion and PK:  All plasma and urine cytisine concentrations and derived PK data 
following administration of cytisine will be listed and the data summarised descriptively. 
Individual and mean plasma concentration time curves will also be plotted. In order to compare 
fed vs fasted conditions, following logarithmic transformation, Cmax, AUC0-∞ , AUC0-t and total 
Ae values will be subjected to an analysis of variance (ANOVA).  Point estimates and 90% 
confidence intervals (CI) will be constructed for the contrast between the two conditions. A 
comparison of Tmax will be performed using the Wilcoxon Signed-Rank test. In addition, the 
Hodges-Lehmann estimate of the median difference in Tmax and 95% confidence interval will be 
presented. 
Safety: All safety data will be listed.   
AEs will be coded using Medical Dictionary for Regulatory Activities (MedDRA) version 20.0 
or higher.  The incidence of treatment emergent AEs (TEAE) will be summarised by organ 
system, preferred term, severity and relationship to study drug.  Abnormal laboratory safety 
results will be listed separately.   
 
DURATION OF STUDY: Approximately 6 weeks for each individual (from screening to 
post-study follow-up).

ETHICS 
1.1. 
Research Ethics Committee  
This study protocol will be submitted to the Research Ethics Committee (REC) for review and 
approval.  The approval of the REC must be obtained before commencement of any study 
procedures. 
The favourable opinion is conditional upon the Sponsor registering the clinical trial in a publicly 
accessible database, within 6 weeks of the first participant recruited.   
All substantial protocol amendments must be approved by the REC responsible for the study.  
Non-substantial amendments will not require prior approval by the REC. 
If the study is stopped due to adverse events (AEs), it will not be recommenced without 
reference to the REC responsible for the study. 
The outcome of the study (e.g. completed) will be reported to the REC responsible for the study 
within 90 days of completion of the last subject’s final study procedures.  In the event of the 
study being prematurely terminated, a summary safety report will be submitted to the REC 
responsible for the study within 15 days. 
A summary of the clinical study report will be submitted to the REC responsible for the study 
within 1 year of completion of the last subject’s final study procedures. 
The REC will be informed that 
 is a commercial organisation and that the study is funded 
by Achieve Life Science. The subjects who take part in the clinical study will be paid for their 
inconvenience and have been informed that there will be no benefits gained by their 
participation. All potential conflicts of interest will be declared by the Investigators.  
1.2. 
Subject Information and Consent 
Potential subjects who volunteer for participation in the study will be informed of the aims, 
methods, anticipated benefits and potential hazards of the study and any possible discomfort it 
may entail.  Information will be given in both oral and written form and in the manner deemed 
appropriate by the Clinical Unit standard operating procedures (SOPs). Each subject will also be 
informed of his/her right to withdraw from the study at any time, for any reason. 
A written explanation (participant information sheet) and informed consent form will be 
provided and the subject will be allowed sufficient time to consider the study information. Prior 
to signing the informed consent form, the subject will be given an opportunity to discuss any 
issues concerning the study with an Investigator who has suitable knowledge of the study and 
will have all questions answered openly and honestly. 
If the subject is willing to participate in the study, the informed consent form will be signed and 
personally dated by the subject and the person taking consent. The subject will receive a copy of 
the informed consent form together with the participant information sheet and the original signed 
informed consent form will be retained with the study records at the Investigator site.  In 
addition, the actions and completion of the consenting process will be recorded in the subject’s 
medical record (i.e., source document).

INTRODUCTION AND BACKGROUND 
2.1. 
Smoking and Health 
Tobacco smoking contributes to some 5 million premature deaths each year worldwide.1 
Smoking is highly addictive, with more than 95% of unaided attempts at cessation failing to last 
6 months.2  Every year that a smoker delays quitting beyond the mid-30s, it has been estimated 
that the person loses 3 months of life expectancy.3  The World Health Organization’s Framework 
Convention on Tobacco Control identifies evidence-based approaches to promote smoking 
cessation, which include mass-media campaigns, tax increases on tobacco, and help for smokers 
wanting to stop.4 
2.2. 
Cytisine 
) containing the active substance cytisine has 
been licensed and marketed in Central and Eastern Europe for several decades by 
 
), but remains relatively unknown outside Eastern Europe despite requests for 
market licensing worldwide.5-7 
Cytisine’s mechanism of action has assisted basic pharmacologists in understanding the complex 
pharmacology of the various subtypes of the nicotinic acetylcholine receptor.8  These studies 
have shown that both nicotine and cytisine bind strongly and preferentially to pre-synaptic α4β2 
receptors9,10 that mediate the release of dopamine in the shell of the nucleus accumbens.  This 
receptor subtype has been implicated in the development and maintenance of nicotine 
dependence11 and was the primary target for the drug varenicline, which has proved effective in

Three studies have evaluated the pharmacokinetics of cytisine in man.  
Study CYT–BIO-02-07 was conducted according to the principles of Good Clinical Practice 
(GCP) and sponsored by 
.  The pharmacokinetic profile of cytisine in plasma was 
determined following administration of 1.5 mg cytisine (in the form of a 
 tablet) in 36 male 
healthy non-smoking volunteers.  All drug administrations were given in the fasted state.  The 
primary PK outcomes are summarised in (Table 1):

Cummulative cytisine levels excreted in the urine during the 24 hours post administration period 
indicated that approximately 64% of administered dose was excreted as parent compound 
(34.71% - 100.24%). 
A second study13 reported the pharmacokinetic profile of cytisine in seven healthy subjects (aged 
between 20 and 39 years) following administration of 3 mg cytisine . Subjects were eligible if 
they were current cigarette smokers at the time of the study and on average, the subjects smoked 
10.6 cigarettes per day. There was no restriction on diet or smoking during the study. The 
primary PK outcomes are summarised in (Table 2):

Cummulative urinary excretion was not evaluated; however, cytisine was still detectable in the

A third study (ACH-CYT-01) examined the pharmacokinetic profile of cytisine in healthy non-
smoking subjects following administration of 3 mg cytisine in the original marketed formulation 
during the fed and fasted states. The primary PK outcomes are summarized in (Table 3):

in the 12-24 hour epoch and were non-zero for all subjects, indicating that renal excretion was 
still ongoing beyond 24 hours after cytisine administration.  However, based on the diminishing 
urinary concentrations over time, it can be concluded that excretion is likely to be complete 
within 48 hours.

RATIONALE FOR THE STUDY 
In the recent bioavailability study evaluating the original marketed formulation for cytisine, no 
food effect was observed for AUC0-∞ (or AUC0-t) with values considered bioequivalent as the 
90% CI for the difference between fed and fasted states fell within the range 80 -125%.  
Consistent with this, the amounts of cytisine recovered from urine within 24 h were similar 
between fed and fasted states, despite Cmax being lower in the fed state. In that study, it was 
concluded that there was no clinically significant food effect for cytisine and there were no 
safety concerns following administration of a single dose of 3 mg cytisine under fed or fasted 
conditions for healthy non-smokers.  
A revised formulation has been subsequently developed, eliminating lactose and introducing 
lower formic acid containing-excipients, to retard the formation of the breakdown substance 
N-formylcytisine. Initial studies indicate that the revised formulation has improved stability at 
24 months and that the shelf-life could be extended to 36 months based on the preliminary 
stability information. This study will evaluate if there is any food effect for cytisine using this 
new formulation in healthy smokers.

STUDY OBJECTIVES 
4.1. 
Primary Objective 
1. To compare the bioavailability (Cmax and AUC0-∞) of cytisine in smokers under fed and 
fasted conditions, following administration of 3 mg cytisine (2 x 1.5 mg cytisine tablets). 
2. To assess the extent of renal elimination (Ae and Ae%) of cytisine via measurement of 
urinary concentrations, following administration of 3 mg cytisine (2 x 1.5 mg cytisine 
tablets). 
4.2. 
Secondary Objectives 
1. To compare the AUC0-t, T½ and Tmax of cytisine in subjects under fed and fasted 
conditions, following administration of 3 mg cytisine (2 x 1.5 mg cytisine tablets). 
2. To assess the safety and tolerability of cytisine in a new formulation at the 3 mg dose 
level under fed and fasted conditions. 
5. 
INVESTIGATIONAL PLAN 
5.1. 
Study Design 
This will be an open-label, randomised, 2-treament period, single-dose crossover Phase I study 
conducted in healthy smokers as shown below:

Figure 1: 
Study Design Overview  
 
The study will be comprised of a pre-study screen, followed by 2 treatment periods (1 and 2) and 
a post-study follow-up.   
Screening (Day -28 to Day -1): Screening assessments will be carried out within 28 days before 
first administration of cytisine.  
Baseline (Day 0): Baseline assessments will be carried out one day before the first 
administration of cytisine.   
Treatment Periods (Day 1 to Day 5):  Eligible subjects will receive a single-dose of cytisine 
under fed and fasted conditions during the 2 treatment periods.  
• Each treatment period will be approximately 2 days’ duration in which plasma and 
urine samples will be collected for 48 hrs.   
• Subjects will arrive at the Clinical Unit on Day 0 and will undergo an overnight fast 
of at least 10 h prior to dosing on Day 1. Randomisation will occur on the morning of 
Day 1, Period 1, at least 1 hour  prior to first dosing. 
• Cytisine will be administered under fasted (after an overnight fast of at least 10 h) or 
fed (after a high fat breakfast) conditions with the last plasma and urine sample 
occurring at 48 h postdose (before the second cytisine dosing on Day 3).  All subjects 
will stay overnight on Day 2 and undergo an overnight fast of at least 10 h prior to 
dosing on Day 3. 
• Pharmacokinetic (PK) samples (plasma and urine) will be collected predose and up to 
48 h postdose during each period for the measurement of plasma and urine cytisine 
concentrations. Safety will also be evaluated at specified times.   
• Final ECGs and blood draw for repeat haematology and chemistries will be obtained 
just prior to discharge on Day 5. 
• There will be at least 48 hours between dose administrations on Day 1 and Day 3. 
Post Study: Post study telephone follow-up will be conducted 6 to 8 days after the last dose of 
cytisine. If any adverse events are recorded at post study telephone assessment, arrangements

will be made with the subject, so that they are followed-up appropriately and the final outcome 
determined.  
The end of study is defined as completion of safety follow-up on all subjects. The maximum 
duration of this study is estimated to be around 6 weeks (screening to last subject’s last visit, via 
telephone contact).   
5.2. 
Discussion of Study Design 
This study design minimizes the influence of inter-subject variability, which is assumed to be 
higher than the intra-subject variability, as each subject will be administered cytisine in both the 
fed and fasted states. As each subject serves as his own control, the precision of the comparison 
should be improved. 
The blood and urine samples for the determination of cytisine plasma and urine concentrations 
will be collected up to 48 hours after cytisine administration. Taking into account the known 
terminal elimination half-life of cytisine (about 4 hours), this sampling schedule is expected to 
provide a reliable estimate of the extent of exposure.  
The washout of at least 48 hours between dose administration will allow a complete elimination 
of cytisine between doses and is deemed sufficiently long to avoid any relevant carry-over effect. 
6. 
SELECTION OF STUDY POPULATION 
Approximately 12 subjects represented in the Urine/PK Analysis Set will be required to 
complete the study.   
The study is to be conducted in healthy subjects who are current smokers.  A healthy subject 
population with carefully considered inclusion/exclusion criteria will avoid the potential for 
interaction of cytisine with any underlying disease state or concomitant medication that might be 
necessary to administer to patients, while ensuring that subjects are fit and well enough for 
participation in the study.  Since smokers are the intended population for cytisine treatment, 
current smokers will be enrolled in the study. 
The following eligibility criteria are designed to select subjects for whom protocol treatment and 
procedures are considered appropriate.  All relevant medical and non-medical conditions should 
be taken into consideration when deciding whether this protocol is suitable for a particular 
subject. 
6.1. 
Inclusion Criteria 
6.1.1. 
To be Confirmed at Screening 
1. Subject is current cigarette smoker. 
2. Healthy males and females between 18 and 55 years of age. 
a. If a female subject of child bearing potential, a negative pregnancy test at screening 
and admission and willing to use an effective method of contraception (unless of non-
childbearing potential or where abstaining from sexual intercourse is in line with the

preferred and usual lifestyle of the subject) from first dose until 3 months after last 
dose of cytisine.  
b. If a female subject of non-child bearing potential, a negative pregnancy test at 
screening and admission.  For the purposes of this study, this is defined as the subject 
being amenorrheic for at least 12 consecutive months or at least 4 months post-
surgical sterilisation (including bilateral fallopian tube ligation or bilateral 
oophorectomy with or without hysterectomy).  Menopausal status will be confirmed 
by demonstrating at screening that levels of follicle stimulating hormone (FSH) fall 
within the respective pathology reference range.  In the event a subject's menopause 
status has been clearly established (for example, the subject indicates she has been 
amenorrheic for 10 years), but FSH levels are not consistent with a post-menopausal 
condition, determination of subject eligibility will be at Investigator's discretion 
following consultation with the Sponsor. 
c. If a male subject, willing to use an effective method of contraception (unless 
anatomically sterile or where abstaining from sexual intercourse is in line with the 
preferred and usual lifestyle of the subject) from first dose until 3 months after last 
dose of cytisine.

[height in m2]. 
4. Subject with no clinically significant abnormal serum biochemistry or haematology 
values within 28 days before the first dose of cytisine.   
5. Subject with negative urinary drugs of abuse screen, determined within 28 days before 
the first dose of cytisine (a positive result may be repeated at Investigator's discretion).

between 90-140 mmHg, diastolic blood pressure (DBP) between 50 and 90 mmHg, and 
pulse rate (PR) between 40-100 bpm, measured on the dominant arm after minimum of 
5 minutes in supine position) determined within 28 days before first dose of cytisine. 
9. Subject must be available to complete the study (including post study follow-up) and 
comply with study restrictions. 
10. Subject must provide written informed consent to participate in the study. 
6.1.2.

Cytisine 
 CONFIDENTIAL 
 
20 
An Investigator will withdraw a subject from the study at any time for any of the following 
reasons: 
• If a subject experiences a serious or intolerable AE, that prevents them from 
continuing. 
• If a subject incurs a significant protocol violation which impacts on their safety or the 
scientific integrity of the study (this will be discussed on a case-by-case basis with the 
Sponsor). 
• At the request of the Sponsor. 
• If it is considered that the subject’s health is compromised by remaining in the study 
or the subject is not sufficiently cooperative. 
• If a subject is lost to follow-up. 
The reasons for any subject withdrawal will be recorded on the study completion form of the 
case report form (CRF). 
If a subject is withdrawn or chooses to withdraw from the study for any reason, every possible 
effort will be made to perform the evaluations described for the post-study follow-up. The data 
collected from withdrawn subjects will be included in the study report. 
In the event of any abnormalities considered to be clinically significant, subjects will be followed 
up with appropriate medical management until values are considered to be clinically acceptable. 
Referral or collaborative care will be organised if considered necessary. 
Since approximately 12 subjects are to be included in the urine excretion/PK dataset to complete 
the study, subjects who withdraw from the study before receiving any study medication will be 
replaced.  Subjects who are withdrawn from the study due to significant drug-related AEs will 
not be replaced.  Replacement of all other subjects withdrawn from the study after receiving 
study medication will be decided on a case-by-case basis by the Principle Investigator (or 
delegate) and Sponsor. 
7. 
RESTRICTIONS PRIOR AND DURING THE STUDY 
To avoid possible negative effects on the measurement of plasma drug concentrations and/or on 
subject’s safety, several restrictions are to be adopted as outlined in the eligibility criteria and in 
the following sections.  
7.1. 
Confinement 
Each subject will complete 2 treatment periods (Period 1 and Period 2) in confinement. This 
period will require 5 nights stay (arrive at the unit in the afternoon of Day 0 and discharged 
48 hours post second cytisine dose on Day 5).

at least 5 minutes before dosing).   
• Lunch will be served: approximately 4 h post-dose. 
• Dinner will be served: approximately 8 h post-dose. 
• Snack will be served: approximately 12 h post-dose. 
The example of a high fat (approximately 50% of total caloric content of the meal) and high-
calorie (approximately 800-1000 calories) breakfast provided in the US Food and Drug 
Administration guidance document for food-effect bioavailability and fed bioequivalence studies 
(Guidance for Industry, U.S. Department of Health and Human Services Food and Drug 
Administration Center for Drug Evaluation and Research (CDER), December 2002) is 
approximately 150, 250 and 500-600 calories from protein, carbohydrate and fat respectively. 
Suggested content to be:  2 eggs fried in butter, 2 strips of bacon, 2 slices of toast, 4 ounces of 
hash brown potatoes and 8 ounces of whole milk.  Consumption of the standardized breakfast 
will be documented. 
7.2.2. 
Fluid Intake 
No fluids (apart from water taken with dose) are allowed from 1 h prior to dosing until 1 h 
afterwards.  Water is then allowed ad libitum. Decaffeinated tea and coffee as well as 
squash/cordial are allowed from 4 h post-dose. 
7.2.3. 
Smoking 
There will be minimal restrictions to smoking during days of confinement, such as all smoking 
must occur within designated area(s) only and subjects cannot smoke during active PK sampling 
period (i.e. subjects must have their last cigarette a minimum of 2 hours before dosing and can 
only start smoking after final PK sample). Subjects will go for a cigarette as a group and will 
need to have their last cigarette before 23:00 while they stay in the clinic. Clinic staff will review 
these guidelines with subjects during confinement and will monitor compliance. 
7.2.4. 
Alcohol Intake 
The consumption of alcohol will be limited to a maximum of 2 units per day from 7 days prior to 
the first dose of cytisine.  Alcohol will be avoided completely for at least 2 days prior to the first 
dose of cytisine and throughout the study period.  Any deviation outside this alcohol intake 
restriction will be assessed on a case-by-case basis at Investigator’s discretion (provided the 


Protocol ACH-CYT-07, 03 April 2018, Version 2.0 
 
Cytisine 
 CONFIDENTIAL 
 
22 
subject’s alcohol intake will not impact in the safety aspects and objectives of the study and the 
subject has a negative alcohol screen prior to dosing). 
7.2.5. 
Caffeine 
Food or drink containing caffeine, including coffee, tea, cola, energy drinks or chocolates will be 
avoided completely for 2 days prior to dosing and whilst the subjects are resident in the Clinical 
Unit (during each dosing period). 
7.2.6. 
Poppy and Sesame Seeds 
Subjects must not eat food containing poppy or sesame seeds for 3 days before drug of abuse 
testing, as consumption can lead to a positive opiate result in the drugs of abuse test. 
7.2.7. 
Grapefruit Juice and Other Restrictions  
No food or drink containing grapefruit, cranberry, or Seville oranges (including marmalade and 
fruit juices), and/or food or drink, sweets, candies or other confectionary containing liquorice 
will be allowed from 7 days before the first dose of cytisine until the study completion. 
Each subject will be questioned on the specific points at admission to the clinical unit (Day 0). If 
a subject admits a non-compliance with these restrictions, the Principal Investigator or attending 
Research Physician will decide whether or not the subject will be permitted to remain in the 
study. Non-compliance with these restrictions will be noted. 
7.3. 
Other Life-Style Restrictions 
7.3.1. 
Strenuous Exercise 
Strenuous exercise must be avoided completely from 3 days before the first dose of cytisine until 
the final study visit. 
7.3.2. 
Blood Donation 
Subjects will be advised that they should not donate blood for at least 3 months after the final 
study visit. 
7.3.3. 
Contraception 
To prevent pregnancy female subjects of childbearing potential and male subjects with female 
partners of child bearing potential must take adequate contraceptive precautions for the entire 
duration of study participation. Adequate contraceptive precautions include: 
1. Established use of oral, injected or implanted hormonal methods of contraception. 
2. Placement of an intrauterine device (IUD) or intrauterine system (IUS).  
3. Barrier methods of contraception: Condom or occlusive cap (diaphragm or cervical/vault 
caps) with spermicidal foam/gel/film/cream/suppository.  
4. Male sterilisation (with the appropriate post-vasectomy documentation of the absence of 
sperm in the ejaculate). [For female subjects on the study, the vasectomised male partner 
should be the sole partner for that subject].

Blinding 
The study is open-label. However, as stated in the EMA guidelines on investigation of 
bioavailability and bioequivalence (CPMP/EWP/QWP/1401/98 Rev.1/Corr** London, 
20 January 2010), analysis of the samples should be conducted without information on treatment, 
therefore staff responsible for drug concentration and ECG analysis will be blinded to the 
treatment schedule.

PRIOR AND CONCOMITANT THERAPY 
Prior Medication: Prescription or non-prescription drugs, including vitamins, herbal and dietary 
supplements should not be taken within 14 days (or 5 half-lives, whichever is longer) prior to the 
first dose of cytisine, unless in the opinion of the Investigator and Sponsor's Responsible 
Physician the medication will not interfere with the study procedures or would compromise 
subject safety. Prescription or non-prescription drugs, including vitamins, herbal and dietary 
supplements taken during the 14 days before the first dose of cytisine, and the reason for taking 
them, will be noted in the subject’s CRF.  
Inclusion of subjects who have taken prior medication will be reviewed on a case-by-case basis 
in relation to the safety aspects and objectives of this study.   
Concomitant Medication: Prescription or non-prescription drugs, including vitamins, herbal 
and dietary supplements should not be taken throughout the duration of the study, with the 
exception of paracetamol (which may be taken as an analgesic to a maximum of 2 g in 24 h 
(500 mg 4 times a day) and ibuprofen (which may be taken as an analgesic to a maximum of 
1.2 g in 24 h (400 mg 3 times a day).  
If intake of ANY prior or concomitant medication is necessary during the study, the daily dosage, 
duration and reasons for administration will be recorded on the subject’s CRF. 
Chewing gum will not be allowed during confinement periods. 
10. 
TREATMENT COMPLIANCE 
Each dose of cytisine will be taken under supervision and a hand and mouth check conducted.  
The exact dosing time for each subject will be recorded on the subject’s CRF.

The pre-dose blood samples will be collected within 60 minutes prior to dosing.  The post-dose 
blood samples will be collected within +/-1 minute from the scheduled sampling time. The clock 
time will be recorded and reported for all blood draws and all subjects.  A deviation greater than 
+/- 2 minutes will be reported as a protocol deviation and its cause will be recorded.  
In case blood sampling for pharmacokinetics and other procedures coincide in time, blood draws 
will have priority unless other procedures are necessary for assuring subject’s safety.  
Immediately upon sampling, the blood sample for pharmacokinetic analysis will be identified 
with a bar-coded label bearing details of study number, subject number, study phase/period, 
sampling time point, sample type and a unique 9-digit identification number. The samples will be 
logged and then centrifuged at 1500 x g, 4°C for 10 minutes. Two equal aliquots of plasma will 
be transferred to polypropylene tubes labeled identically to the original blood sample (except 
sample type being plasma instead of whole blood) and logged when stored at approximately -
20°C, pending analysis.   
The blood samples will be placed on ice immediately and centrifuged within 60 minutes of being 
taken.

unique 9 digit identification number. 
The urine collection containers will be kept chilled (at approximately 4°C) during collections.  
After the termination of each fractional collection the volume excreted will be recorded and 2 x 
10 mL aliquots retained for determination of cytisine concentrations.  The aliquots will be 
labelled identically to the original collection container and will be stored at -20°C pending 
analysis. 
12.3. 
Determination of Plasma and Urine Drug Concentrations 
Cytisine concentrations (ng/mL) in plasma and urine will be determined using a validated liquid 
chromatography tandem mass spectrometry method and will be conducted in accordance with 
Good Laboratory Practice regulations and guidelines. Methods validation must be completed 
prior to start of the analysis. 
The sample analysis will only begin after the last sample of a study subject is collected. All 
samples from each subject will be analyzed in the same analytical batch.  In each run, standard 
and quality control samples will be distributed throughout the batch containing study samples. 
Samples with concentrations above the ULOQ will be diluted and re-assayed.  
Full details, including the lower (LLOQ) and upper (ULOQ) limits of quantification range,  will 
be provided in a Bioanalytical Phase Plan written by 
 
Plasma and urine samples of withdrawn subjects should also be analysed for drug concentrations 
and pharmacokinetic parameters (providing withdrawal was not due to withdrawal of consent).

samples, will be given in the Analytical Study Report (ASR). 
12.4. 
Incurred Samples Reanalysis 
In order to establish the reproducibility of the assay, 10% of the first 1000 samples and 5% of the 
number of samples exceeding 1000 samples will be reanalyzed. 
Both the original and replicate values will be presented in the Analytical Study Report with the 
percent difference between the two values. The original value will be the one used for 
pharmacokinetic analysis.

SAFETY ASSESSMENTS 
13.1. 
Subject’s Safety 
Only healthy subjects are eligible for the study.  The healthy status will be determined by 
meeting the inclusion and exclusion criteria. Subjects’ safety will be monitored during the study.  
Adverse events will be monitored and recorded throughout the study.  
Prior to the first cytisine dosing only, the Principal Investigator or Research Physician will assess 
the clinical significance of results of laboratory investigations for haematology and serum 
chemistry values outside the defined normal ranges, as provided by the laboratory. All changes 
from screening that are observed on Day 2 during the study and meet clinically-significant 
definitions for laboratory adverse events will be recorded. 
In addition to the planned times, any safety procedures can be performed at any time considered 
necessary by the Principal Investigator or attending Research Physician.  
On each cytisine dosing day, at least one physician (Principal Investigator or Research 
Physician) will physically remain at the clinical site for investigational product administration 
and until 4 hours post-dose, and will remain available on call at all times during the entire period 
of the study.  
In case any clinically significant abnormality is observed at pre-dose, Principal Investigator or 
attending Research Physician will decide whether the subject will proceed to investigational 
product administration or will be withdrawn from the study. 
Safety will be assessed by consideration of all adverse events reported by or elicited from the 
subject and abnormalities detected on haematology, serum chemistry tests, urinalysis, and 
12-lead ECG. Worsening of other preexisting medical conditions and any changes to 
concomitant medications/treatments will also be taken into account in this evaluation.  
All adverse events (serious and non-serious) beginning on Day 1 (prior to dosing) through post-
study follow-up telephone call will be recorded in the subject’s CRF.

13.2. 
Adverse Events 
13.2.1. 
Definition of Adverse Event 
The definitions are adopted in accordance with the Directive 2001/20/EC, ICH-E2A and the 
European Commission Detailed Guidance 2011/C 172/01. 
An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical trial subject 
administered a medicinal product and which does not necessarily have a causal relationship with 
the treatment. 
An AE can therefore be any unfavorable and unintended sign (including any clinical significant 
abnormal laboratory finding), symptom, or disease temporally associated with the use of an 
investigational medicinal product, whether or not considered related to the investigational 
medicinal product. 
An Adverse Drug Reaction (ADR) means all untoward and unintended responses to a 
medicinal product related to any dose administered.  The phrase ‘response to a medicinal 
product’ means that a causal relationship has at least a reasonable possibility, i.e. the relationship 
cannot be ruled out and is judged by the Investigator as at least possible (see definition below). 
An Unexpected Adverse Drug Reaction (UADR)/Unexpected Adverse Event (UAE) means 
an adverse reaction/event, the nature or severity of which is not consistent with the applicable 
product information, namely in the Investigator Brochure for an unauthorized investigational 
product or in the SmPC for an authorized product. 
The expected/unexpected status should be evaluated and assessed, by the Sponsor, based on the 
reference safety information available since expectedness in Pharmacovigilance refers strictly to 
the information listed or mentioned in the applicable reference safety information and not to 
events that might be anticipated from knowledge of the pharmacological properties of a 
substance or because it was foreseeable due to the health status (e.g., age, medical history) of the 
study subjects. 
A Serious Adverse Event (SAE) or Serious Adverse Reaction (SAR) is defined as an AE that 
results in any of the following: 
• Results in death  
• Is life-threatening  
• Requires hospitalization or prolongs existing inpatient’s hospitalization 
• Results in persistent or significant disability or incapacity 
• Results in a congenital abnormality or birth defect 
• Is an important medical event which requires medical intervention to prevent any of 
the above outcomes 
SUSARs: AEs which meet all of the following criteria: 
• Serious. 


Protocol ACH-CYT-07, 03 April 2018, Version 2.0 
 
Cytisine 
 CONFIDENTIAL 
 
35 
• Unexpected (i.e., is not consistent with the applicable product information e.g. 
Investigator's brochure for an unapproved cytisine or SmPC for an authorised 
product). 
• There is at least a reasonable possibility that there is a causal relationship between the 
event and the medicinal product.  
will be classified as suspected unexpected serious adverse reactions (SUSARs). 
Important medical events are those which may not be immediately life-threatening, but may 
jeopardize the subject and may require intervention to prevent one of the other serious outcomes 
listed above. Examples of such events are intensive treatment in an emergency room or at home 
for allergic bronchospasm, or blood dyscrasias or convulsions that do not result in 
hospitalization. 
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. For example, drug-induced hepatitis that 
resolves without evidence of hepatic failure would not be considered life threatening even 
though drug-induced hepatitis can be fatal. 
Inpatient hospitalization or prolongation of existing hospitalization means that hospital inpatient 
admission and/or prolongation of hospital stay were required for treatment of AE or occurred as 
a consequence of the event. It does not refer to pre-planned elective hospital admission for 
treatment of a pre-existing condition that has not significantly worsened, or to diagnostic 
procedures. 
13.2.2. 
Recording of Adverse Events 
All of the following details will be recorded in the subject’s CRF for each AE: 
• Full description of AE. 
• Date and time of onset. 
• Date and time of resolution. 
• Severity of event, to be assessed by an Investigator in accordance with the definitions 
below. 
• Relationship to cytisine to be assessed by an Investigator in accordance with the 
definitions below. 
• Action taken (if any). 
• Outcome and details of any further follow-up. 
Adverse events documented in the CRF without a stop date should be reviewed at the end of 
each treatment period until final resolution or until it is medically justifiable to stop further 
follow up (e.g. a chronic condition has been reached.)  Documentation of adverse events should 
be updated as necessary.

Cytisine 
 CONFIDENTIAL 
 
36 
13.2.3. 
Grades of Adverse Event Severity 
The following grades will be used by an Investigator to describe the severity of all AEs 
(including clinically-significant laboratory AEs) as shown in Table 8.  Only 1 severity grade will 
be used for each AE (e.g. mild - moderate is not acceptable). 
Table 8: 
Adverse Event Severity 
Severity of AE 
Definition 
Mild 
No interference with activity 
Moderate 
Some interference with activity requiring no or minimal  
medical intervention 
Severe 
Prevents daily activity and requires medical intervention 
If an adverse event has multiple aspects, the aspect in the highest intensity will be graded. It is 
emphasized that the term severe is a measure of intensity; thus a severe AE is not necessarily 
serious. For example, itching for several days may be rated as severe; however, may not be 
clinically serious.  
13.2.4. 
Assessment of Causal Relationship 
The causal relationship between an adverse event and cytisine will be determined and 
documented by the responsible Investigator, or designee, according to best medical judgment as 
shown in (Table 9). 
Table 9: 
Assessment of Causal Relationship 
Category 
Description 
Not Related 
The event is definitely not associated with cytisine.  
Unlikely 
The event was most probably produced by other factors such as the subject’s clinical 
state, therapeutic intervention or concomitant therapy, and does not follow a known 
response pattern to cytisine 
Possible 
The event follows a reasonable temporal sequence from the time of cytisine 
administration, and/or follows a known response pattern to the investigational 
product, but could have been produced by other factors such as the subject’s clinical 
state, therapeutic intervention or concomitant therapy. 
Probable 
The event follows a reasonable temporal sequence from the time of cytisine 
administration, and/or follows a known response pattern to the product, and could not 
have been produced by other factors such as the subject’s clinical state, therapeutic 
intervention or concomitant therapy. 
Definite 
The event follows a reasonable temporal sequence from the time of cytisine 
administration, and/or follows a known response pattern to the product, and could not 
have been produced by other factors such as the subject’s clinical state, therapeutic 
intervention or concomitant therapy, and either occurs immediately following 
investigational product administration, or improves on stopping the investigational 
product. 
13.2.5. 
Reporting of Serious Adverse Events 
Any new SAE that occurs during a treatment period should be recorded and reported 
immediately. All SAEs including those that are ongoing at the end of study treatment will be 
followed until each event resolves or is assessed as chronic.

In order to satisfy regulatory requirements, any Serious Adverse Event, whether deemed study 
drug-related or not, must be reported to the Sponsor or designee as soon as possible after the 
Investigator or coordinator has become aware of its occurrence.  SAE form completion and 
reporting must not be delayed even if all of the information is not available at the time of the 
initial contact. 
SAEs must be reported within 24 h of knowledge of the event by submitting an initial SAE 
report via email or fax to

STATISTICAL METHODS 
15.1. 
Primary Objectives and Analysis 
All data recorded during the course of the study or derived during the programming phase will be 
presented in individual data listings. 
Unless specified otherwise, continuous variables will be summarised with the following 
descriptive statistics: n (number of observations), arithmetic mean, standard deviation (SD), 
minimum value, median and maximum values. For PK summaries, the geometric mean and 
coefficient of variation (%CV) will also be used to summarise the data. Categorical data will be 
summarised with frequencies and percentages.  
Unless specified otherwise, the minimum and maximum statistics will be presented with the 
same precision as the original data.  The mean, median and geometric mean will be presented to 
one more decimal place than the original data. The SD will be presented to two more decimal 
places than the original data. Unscheduled measurements will be listed in the individual data 
listings.  With the exception of baseline, unscheduled measurements will be excluded from the 
descriptive statistical analysis.  In case an unscheduled measurement is performed immediately 
after the scheduled measurement due to an error in the previous measurement, the unscheduled 
measurement will be included in the analysis and the original erroneous measurement will be 
excluded. 
For subject characteristics and safety analyses, missing data will not be replaced; descriptive 
statistics and statistical analysis will be performed on the basis of the available data only.

Subject Populations for Analyses 
15.2.1. 
Safety Analysis Set 
All subjects who received at least one dose of cytisine will constitute the Safety Set.  
15.2.2. 
PK Analysis Set 
• Subjects will be allocated to the PK Analysis Set on a per treatment basis. The PK 
Analysis Set for a treatment will include all subjects who receive the one dose of 
cytisine, do not violate the protocol in a way that may invalidate or bias the results 
(major protocol deviation) and have sufficient plasma concentration-time profiles 
complying with the following criteria: 
• Do not have an occurrence of vomiting or diarrhoea which renders the plasma 
concentration profile unreliable (e.g. if vomiting occurs at or before 2 times median 
Tmax);  
• Do not use a concomitant medication which renders the plasma concentration profile 
unreliable;  
• Do not have a pre-dose plasma concentration that is greater than 5% of the 
corresponding Cmax; 
• Have at least one evaluable plasma concentration that is preceded by a lower 
evaluable concentration and followed by a lower evaluable concentration for the 
calculation of Cmax, Tmax and AUCs (i.e. at least 3 evaluable concentrations in total). 
In order to be included in the statistical comparisons, a subject is required to be included in the 
PK Analysis Set for both treatments. 
15.2.3. 
Urine Excretion Analysis Set 
Subjects will be allocated to the Urine Excretion Analysis Set on a per treatment basis. The 
Urine Excretion Analysis Set for a treatment will include all subjects who receive the one dose of 
cytisine, do not violate the protocol in a way that may invalidate or bias the results (major 
protocol deviation) and comply with the following criteria: 
• Do not have any missing urine excretion collections (i.e. missing urine in a collection 
period specified in Section 12.2) which renders analysis of overall excretion 
unreliable; 
• Do not have an occurrence of vomiting or diarrhoea which renders the urine excretion 
profile unreliable (e.g. if vomiting occurs at or before 2 times median Tmax derived 
from plasma data);  
• Do not use a concomitant medication which renders the urine excretion profile 
unreliable.

In order to be included in the statistical comparisons,  a subject is required to be included in the 
Urine Excretion Analysis Set for both treatments. 
 
15.3. 
Subjects Characteristics 
Demographic data will be summarised (age, height, weight, BMI and race) by gender and 
overall. Separate summaries of  demographics,  will be provided for both safety and PK/Urine 
excretion analysis sets if applicable. Subject disposition and analysis sets (safety, PK) will also 
be listed and summarised by frequency. 
The protocol violations will be listed per subject, describing the nature of the violation. Subjects 
failing to complete the study (as well as the date and reasons for discontinuation) will be 
displayed. Time may be added if relevant to the nature of the violation. 
Medical history will be referred in accordance with the Medical Dictionary for Regulatory 
Activities (MedDRA), version 20.0 or higher. Medications will be mentioned according to the 
Anatomical Therapeutic Chemical (ATC) classification system using WHO Drug Dictionary. 
15.4. 
Sample Size Calculation 
A total of 12 subjects will be randomized to the study, with approximately 6 subjects per 
treatment schedule arm.  
Subject numbers are based on the following guidance: In study ACH-CYT-01, geometic mean 
AUC0-∞ values in the fed and fasted states were 168 ng.h/mL and 173 ng.h/mL respectively 
(yielding a geometric mean ratio of 0.97) with an intra subject CV% of approximately 6%. 
Geometric mean Cmax values in the fed and fasted states were 22.3 ng/mL and 29.8 ng/mL 
respectively (yielding a geometric mean ratio of 0.75) with an intra subject CV% of 
approximately 23%. Although this study is not a formal comparison of bioequivalence the 
assumptions used for a typical bioequivalence study have been used in order to estimate an 
appropriate sample size. Based on the assumption that similar results will be observed for this 
study, a sample size of 4 subjects would be sufficient to detect a 20% difference in AUC0-∞ 
between the treatments with a power of 80%, an alpha of 5% and a fed/fasted ratio of 1. 
Therefore, 12 subjects, which is the minimum number of subjects recommended for this type of 
trial, should be sufficient to compare the bioavailability with respect to AUC in the fed and 
fasted states. Given that the Cmax geometric mean ratio observed in the previous study did not fall 
within the bioequivalence range, likely due to the slower rate of absorption in the fed state, the 
sample size has been based on AUC0-∞.   
Subjects who withdraw from the study before receiving any study medication will be replaced.  
Subjects who are withdrawn from the study due to significant drug-related AEs will not be 
replaced.  Replacement of all other subjects withdrawn from the study after receiving study 
medication will be decided on a -case-by-case basis by the Principle Investigator (or delegate) 
and Sponsor.

Plasma and Urine Concentrations 
Descriptive statistics to summarize plasma and urine concentrations at each time point will be 
presented.   
Individual drug plasma concentrations versus time profiles will be plotted per subject on both a 
linear and a semi-logarithmic scale. For plotting of individual data in linear scale, concentrations 
below the LLOQ will be replaced by zero. For plotting of individual data in semi-logarithmic 
scale, concentrations below the LLOQ will be set to missing.  Graphical presentation of 
individual data will be based on actual blood sampling times. 
Arithmetic mean drug plasma concentration versus time profiles will be presented on both a 
linear and a semi-logarithmic scale.   
The post-dose blood samples will be collected within ±2 minutes from the scheduled sampling 
time. A deviation greater than ±2 minutes will be reported as a protocol deviation.   
15.6. 
Estimation of pharmacokinetic parameters 
Plasma: The following pharmacokinetic parameters for cytisine will be derived by standard non-
compartmental methods from the concentration versus time profiles: 
Table 10: 
Cytisine Pharmacokinetic Parameters 
Parameter 
Description 
Cmax 
Maximum observed plasma concentration post dose, directly obtained from the observed 
concentration versus time profile. 
Tmax 
Time of occurrence of maximum observed plasma concentration. 
AUC0-t 
Area under the plasma concentration versus time curve (AUC) from time zero to the last 
sampling time at which concentrations were at or above the LLOQ, calculated by the 
linear-up/log-down trapezoidal rule. 
AUC0-∞ 
Total AUC from time zero to infinity, calculated as AUC0-∞ = AUC0-t + (Clast/λz), where Clast 
is the last measurable plasma concentration and λz the apparent terminal elimination rate 
constant. 
%AUC 
Residual area or percentage of extrapolated part for the calculation of AUC0-∞, calculated as 
100*[1-(AUC0-t/AUC0-∞)] 
λz 
Apparent terminal elimination rate constant. 
T1/2 
Apparent terminal elimination half-life, calculated from ln 2/λz. 
No values of λz, AUC0-∞, %AUC and T1/2 will be reported for cases where λz cannot be reliably 
determined. 
Pharmacokinetic parameters will be estimated from the plasma concentration versus time 
profiles for all subjects in the safety analysis set.  Actual sampling times will be used for the 
pharmacokinetic analysis. All calculations will be performed using raw data.  
The terminal elimination rate constant (λz) will be determined by plotting the concentration data 
versus time on a semi-logarithmic scale.  The parameter will be estimated by linear least square 
regression analysis, using the last three (or more) non-zero concentrations.  The upper and the 
lower timepoints, as well as the number of timepoints, used for λz estimation will be reported.  
AUC0-t will be calculated by the linear-up/log-down trapezoidal method.

Individual pharmacokinetic parameters and descriptive statistics for the pharmacokinetic 
parameters obtained for each treatment will be presented.  If no reliable pharmacokinetic 
parameter could be determined for more than 1/3 of the subjects, only the minimum and 
maximum values will be presented for that parameter and all other descriptive statistics will be 
omitted.  Missing pharmacokinetic parameter data will not be imputed.  
Urine: The urine PK parameters amount excreted in urine over time (Ae) and percent of drug 
excreted in urine (Ae%) will be derived from the urine concentration-time data for all subjects in 
the safety analysis set. Derived urine PK parameters will be listed and summarised by treatment.   
15.7. 
Pharmacokinetic Analysis 
Following logarithmic transformation, Cmax, AUC0-t, AUC0-∞ and Total Ae values will be 
subjected to an analysis of variance (ANOVA) including fixed effects for sequence, period, 
treatment and subject nested within sequence. Point estimates and 90% confidence intervals (CI) 
will be constructed for the contrasts between fed and fasted states using the residual mean square 
error obtained from the ANOVA.  The point and interval estimates will be back-transformed to 
give estimates of the ratios of the geometric least squares means (LSmean) and corresponding 
90% CI. In addition, estimated geometric means will be presented. 
A comparison of Tmax will be performed using the Wilcoxon Signed-Rank test. In addition, the 
Hodges-Lehmann estimate of the median difference in Tmax and 95% CI will be presented.

1 INTRODUCTION 
1.1 
GENERAL  
This statistical analysis plan (SAP) describes the statistical methods to be used during the reporting and 
analysis of data collected under the ACH-CYT-07 protocol dated 3rd April 2018 and should be read in 
conjunction with the study protocol and case report form (CRF).   
 
This version of the plan has been developed using the protocol version 2.0 dated 3rd April 2018 and the 
annotated CRF.  Any further changes to the protocol or CRF will be reviewed for potential impact on 
the SAP, which will be amended if it is deemed necessary. 
 
Draft versions of the SAP will undergo review by the Statistical Reviewer, Project Manager, PK Analyst, 
Medical Writer, Principal Investigator and the Sponsor/Sponsor representative. The analysis plan will be 
finalised and approved by the Sponsor prior to Database Lock (DBL). 
 
 
1.2 
CHANGES FROM PROTOCOL 
• 
Vital signs summary included. 
• 
The definitions of the PK Set and Urine Excretion Set have been amended to align with the 
ACH-CYT-01 study. Subjects will be required to receive both doses of cytisine in order to be 
included in the PK/Urine Excretion Set rather than just one dose,  
• 
The PK parameters, CL/F and Vd/F, will also be presented in line with FDA guidance.

Not applicable. 
 
2 STUDY OBJECTIVES 
This study will evaluate if there is any food effect for cytisine in a new formulation and further define 
renal elimination of cytisine over 48 hours.  
 
Primary Objective: 
The primary objectives of this study are:  
1. To compare the bioavailability (Cmax and AUC0-∞) of cytisine in smokers under fed and fasted 
conditions, following administration of 3 mg cytisine (2 x 1.5 mg cytisine tablets). 
 
2. To assess the extent of renal elimination (Ae and Ae%) of cytisine via measurement of urinary 
concentrations, following administration of 3 mg cytisine (2 x 1.5 mg cytisine tablets). 
 
Secondary Objectives: 
The secondary objectives of this study are: 
1. To compare the AUC0-t, T½, and Tmax of cytisine in subjects under fed and fasted conditions, 
following administration of 3 mg cytisine (2 x 1.5 mg cytisine tablets).

3 STUDY DESIGN 
3.1 
OVERVIEW 
This is an open-label, randomized, 2-period, single-dose crossover Phase I study conducted in 12 healthy 
smokers to determine the comparative bioavailability and renal elimination of cytisine following single-
dose administration under fed and fasted conditions.  
 
 
Figure 1: Study Design Overview 
 
 
 
The study is comprised of a pre-study screen, followed by 2 treatment periods (1 and 2) and a post-
study follow-up. Screening assessments will be carried out within 28 days prior to first administration of 
cytisine. Eligible subjects will receive a single dose of cytisine under fed and fasted conditions during 2 
treatment periods. Each treatment period will be of approximately 2 days duration in which blood and 
urine samples will be collected over 48 h period post-cytisine dosing. Subjects will arrive at the Clinical 
Unit on Day 0 and will undergo an overnight fast of at least 10 h prior to first dosing on Day 1. 
Randomisation will occur on the morning of Day 1, Period 1, and cytisine will be administered under 
fasted (after an overnight fast of at least 10 h) or fed (after a high fat breakfast) conditions. Subjects will 
complete all 48 h post-dose assessments prior to starting Period 2 and the second dosing day on Day 3. 
A Post-Study telephone follow-up will be conducted 6 to 8 days after the second dose of cytisine.  
 
 
3.2 INCLUSION AND EXCLUSION CRITERIA 
To be eligible for inclusion into this study, each subject must fulfil all inclusion criteria and not violate 
any exclusion criteria (for the protocol under which they are entered) during screening prior to 
randomisation. Details of the inclusion and exclusion criteria are presented within the protocol (sections 
6.1, 6.2).

3.5 SAMPLE SIZE CONSIDERATIONS 
A total of 12 subjects will be randomized to the study, with 6 subjects per treatment schedule arm.  
Subject numbers are based on the following guidance:  In study ACH-CYT-01, geometric mean AUC0-∞ 
values in the fed and fasted states were 168 ng.h/mL and 173 ng.h/mL respectively (yielding a geometric 
mean ratio of 0.97) with an intra subject CV% of approximately 6%. Geometric mean Cmax values in the 
fed and fasted states were 22.3 ng/mL and 29.8 ng/mL respectively (yielding a geometric mean ratio of 
0.75) with an intra subject CV% of approximately 23%. Although this study is not a formal comparison 
of bioequivalence the assumptions used for a typical bioequivalence study have been used in order to 
estimate an appropriate sample size. Based on the assumption that similar results will be observed for 
this study, a sample size of 4 subjects would be sufficient to detect a 20% difference in AUC0-∞ between 
the treatments with a power of 80%, an alpha of 5% and a fed/fasted ratio of 1. Therefore, 12 subjects, 
which is the minimum number of subjects recommended for this type of trial, should be sufficient to 
compare the bioavailability with respect to AUC in the fed and fasted states. Given that the Cmax 
geometric mean ratio observed in the previous study did not fall within the bioequivalence range, likely 
due to the slower rate of absorption in the fed state, the sample size has been based on AUC0-∞.  
Subjects who withdraw from the study before receiving any study medication will be replaced. Subjects 
who are withdrawn from the study due to significant drug-related AEs will not be replaced.  Replacement 
of all other subjects withdrawn from the study after receiving study medication will be decided on a 
case-by-case basis by the Principle Investigator (or delegate) and Sponsor.   
 
3.6 RANDOMISATION  
Subjects will be allocated to a treatment schedule (sequence) in accordance with a randomisation code 
produced by
 using the PROC PLAN procedure of SAS® version 9.3. Treatment schedules are as 
follows: 
Schedule A (6 subjects): 
• 
Period 1: Cytisine (2 x 1.5 mg tablets) will be administered 30 minutes after the start of a high 
fat breakfast (fed state) with 240 mL water.   
• 
Period 2: Cytisine (2 x 1.5 mg tablets) will be administered after the overnight fast of at least 10 
hours (fasting state with 240 mL water.   
Schedule B (6 subjects): 
• 
Period 1: Cytisine (2 x 1.5 mg tablets) will be administered after the overnight fast of at least 10 
hours (fasting state with 240 mL water.   
• 
Period 2: Cytisine (2 x 1.5 mg tablets) will be administered 30 minutes after the start of a high 
fat breakfast (fed state) with 240 mL water.   
Subjects will be numbered sequentially from 001 (i.e. 001, 002 etc.). Any replacement subjects will be 
assigned the same randomisation as the subjects they are replacing with 100 added to the subject number 
(i.e. 101 would replace 001 etc.).

Study drug/IMP: Study drug/IMP means 3 mg cytisine (2 x 1.5 mg cytisine tablets). 
Treatment: Treatment means 3 mg cytisine in the fed or fasted state. 
Baseline: In general, baseline is defined by subject and by variable as the last non-missing value (including 
repeats) before the first dose of study drug. This is normally the pre-dose assessment on Day 1 but if 
this assessment is missing (or not planned) then the assessment at the Screening/Day 0 visit will be used 
instead if available. 
Study Day: Study day is the number of days since start of treatment where the date of first dose is 
counted as Day 1. 
Bleed Time Deviation: Actual time of blood sample – theoretical time of blood sample. 
Protocol Deviation: a deviation related to study inclusion or exclusion criteria, conduct of the trial, 
subject management or subject assessment. This refers to any change, divergence, or departure from 
the study design or procedures defined in the protocol. Deviations recorded by the Project Manager or 
detected by Data Management or by statistical programming checks will be identified and discussed at 
the Data Review Meeting (DRM) before Database Lock (DBL). All protocol deviations within the study 
database will be classified as either ‘Major’ or ‘Minor’ prior to DBL, details of which will be included 
within the Protocol Deviations listing. 
6 ANALYSIS SETS 
Membership of the analysis sets will be reviewed and agreed prior to DBL. These will be reviewed by 
the Sponsor, Study Statistician, PK analyst and Project Manager and signed off. If PK data is not available 
at the time of DBL, then subjects will be assumed to be included in the analysis set unless the PK data 
provide reason to exclude a subject, in which case this will be discussed with the Sponsor and 
documented within the Analysis Sets listing (Listing 16.2.3.1). 
 
6.1 
SAFETY SET 
All randomised subjects who receive at least one dose of cytisine will constitute the Safety Set. 
This analysis set will be used for baseline and safety summaries as well as for all study listings. 
 
6.2 PK SET 
 The PK Set will include all subjects who receive both doses of cytisine and have sufficient plasma 
concentration-time profiles complying with the following criteria: 
• 
Do not have an occurrence of vomiting or diarrhoea which renders the concentration profile 
unreliable (e.g. if vomiting occurs at or before 2 times median Tmax);  
• 
Do not use a concomitant medication which renders the concentration profile unreliable;  
• 
Do not have a pre-dose concentration that is greater than 5% of the corresponding Cmax;

• 
Have at least one evaluable concentration that is preceded by a lower evaluable concentration 
and followed by a lower evaluable concentration for the calculation of Cmax, Tmax and AUCs (i.e. 
at least 3 evaluable concentrations in total); 
• 
Do not violate the protocol (major protocol deviation) in a way that may invalidate or bias the 
results. 
 
6.3 URINE EXCRETION SET 
 The Urine Excretion Set will include all subjects who receive both doses of cytisine and have sufficient 
urine excretion profiles complying with the following criteria: 
• 
Do not have any missing urine excretion collections (i.e. missing urine in a collection period 
specified in section11.4.3) which renders analysis of overall excretion unreliable;  
• 
Do not have an occurrence of vomiting or diarrhoea which renders the urine excretion profile 
unreliable (e.g. if vomiting occurs at or before 2 times median Tmax derived from plasma data);  
• 
Do not use a concomitant medication which renders the concentration profile unreliable;  
• 
Do not violate the protocol (major protocol deviation) in a way that may invalidate or bias the 
results.

pharmacokinetic team in order to derive the PK parameters using Phoenix WinNonlin 6.4.  Derived PK 
parameters will be received by the Statistics department from the Project Manager/PK analyst in a 
SAS.xpt file in an agreed format and then stored as a SAS dataset and subsequently within SDTM/ADaM 
domains. 
 
9.2 RANDOMISATION LIST 
 
The randomisation list will be uploaded to a SAS dataset and incorporated into the relevant 
SDTM/ADaM domains. 
 
 
9.3 PROGRAMMING AND DATA REVIEW 
 
Programming of datasets, tables, figures and listings may be ongoing while study data management 
activities are in progress.  
Prior to DBL, a review of the clinical database (i.e. CRF data, laboratory data) in the form of Excel data 
listings will be conducted.  A Data Review Meeting (DRM) will be held to discuss the outcome of this 
review, any potential impact on the analyses, analysis sets and protocol deviations.  Once all data issues 
have been resolved and the analysis sets approved, the database will be locked.  The SDTM/ADaM 
datasets will be finalised and the final run of outputs and quality control (QC) will take place.

10 STATISTICAL METHODS 
10.1 GENERAL PRINCIPLES 
• 
All statistical methods will be based on the International Conference on Harmonisation (ICH) 
E9 document “Statistical Principles for Clinical Trials”. 
• 
All data collected will be presented within data listings and any unscheduled visits will be listed.  
• 
Data will be summarised by treatment and overall (data from both treatments pooled) where 
appropriate. The format of the summaries is defined in the shells at the end of this document. 
• 
In summary and analysis tables of continuous variables, standard descriptive statistics (N 
[number within population], n [number of observations included in analysis], mean, standard 
deviation [SD], median, minimum and maximum) will be presented. Least squares mean (LS 
mean) and 90/95% confidence interval (CI) will be presented in the statistical analysis outputs as 
appropriate. For PK summaries, geometric mean, and coefficient of variation (%CV) will also be 
used to summarise the data.  
• 
Unless otherwise specified, the minimum and maximum statistics will be presented in summary 
tables to the same number of decimal places as the original data.  The mean, median, LS mean, 
geometric mean and CI will be presented to one more decimal place than the original data. SD 
will be presented to two more decimal places than the original data. %CV will be presented to 
one decimal place. 
• 
In summary tables of categorical variables, the number of non-missing observations by category 
will be presented along with percentages. Unless otherwise specified, the denominator for each 
percentage will be the number of non-missing observations. All percentages will be presented 
to one decimal place. 
• 
All plots will use a linear time scale for the nominal times of the visits and will be labelled by 
time point. 
• 
Original values will be used in summary tables, unscheduled measurements will be listed only.  
However, where repeats of baseline values occur, the last assessment will be used within any 
summary tables and used to calculate change from baseline. In case an unscheduled measurement 
is performed immediately after the scheduled measurement due to an error in the original 
measurement, the unscheduled measurement will be included in the analysis and the original 
erroneous measurement will be excluded. 
• 
The date format for all output presentations will be as captured in the database. 
• 
All statistical analysis will be performed using SAS 9.3 or higher. 
• 
All hypothesis testing will be carried out at the 5% (2-sided) significance level unless stated 
otherwise.  
• 
P-values will be rounded to four decimal places.  P-values less than 0.0001 will be reported as 
<0.0001 in tables.   
• 
Generally, character values will be left aligned and numeric values will be decimally aligned. 
• 
If any of the assumptions underlying the formal statistical methods proposed are violated during 
the analysis of the final data, alternative statistical methods will be used and any changes 
documented in the statistical methods section of the clinical study report (CSR), including the 
rationale for use.

• 
For numeric data which includes non-numeric values (e.g. PK data reported as BLQ or 
laboratory results reported as < 10 or >100) the following principles will be applied when 
summarising the data: 
 BLQ will be replaced with a zero. 
 Results reported as <x or >x will be treated as x. 
 
10.2 STRATIFICATION AND COVARIATE ADJUSTMENT 
Not applicable. 
 
 
10.3 MISSING DATA 
Generally, no methods to impute missing data will be used.  However, for the purpose of calculating 
change from baseline, in the instance of a missing baseline result for Period 1 (generally the assessment 
at Day 1, Pre-Dose) the results obtained at the Screening/Day 0 visit will be used instead, if available. 
Missing Period 2 baseline results will not be replaced. 
 
In the instance of missing pharmacokinetic blood samples, the linear trapezoidal rule will be employed 
between the samples immediately before and after the missing sample for the AUC calculations.

deviations will be presented including major/minor classification. A data listing presenting subject 
eligibility for each analysis set and the reason for exclusion from an analysis set will also be presented.  
 
11.2 SUBJECT CHARACTERISTICS AT BASELINE 
11.2.1 Demographic and Baseline Characteristics 
Demographic data will be listed (including informed consent information) and descriptive statistics for 
the continuous variables age, height, weight and BMI and frequencies for the categorical variable race 
will be tabulated by gender and overall.  
Demographic and baseline data will be listed and summarised using the Safety Set. Demographic data 
may also be summarised using the PK Set/Urine Excretion Set, if appropriate. 
 
11.3 EFFICACY ANALYSES 
Not applicable. 
 
11.4 PK ANALYSES 
The primary analysis sets for summaries of plasma and urine PK data will be the PK Set and Urine 
Excretion Set respectively. If the PK Set/Urine Excretion Set and the Safety Set are not equivalent, then 
all PK summaries described below will also be produced for the Safety Set.  
11.4.1 Plasma Concentration Data 
Plasma PK samples will be collected for measurement of cytisine at the following time points during each 
period: Pre-dose, 15 min, 20 min, 30 min, 45 min, 1h, 1.5h, 2h, 2.5h, 3h, 4h, 6h, 8h, 12h, 14h, 16h, 24h 
and 48h post-dose. 
 
Cytisine concentrations in plasma will be listed and summarised for each treatment using the descriptive 
statistics N, n, arithmetic mean, arithmetic standard deviation (SD), coefficient of variation (CV%), 
minimum, median and maximum.  
 
The individual subject plasma cytisine concentration profiles over time will be presented graphically using 
actual blood sampling times on a linear and semi-logarithmic scale for each subject with both treatments

presented on the same plot. Arithmetic mean plasma cytisine concentration profiles over time will be 
presented on linear and semi-logarithmic scales.  
 
For inclusion within the summary tables and linear scale plots, concentrations below the limit of 
quantification (BLQ) will be assigned a value of zero. Concentrations above the upper limit of 
quantification (ULOQ) will be obtained via dilution into the calibration range and are valid results. For 
inclusion within the semi-logarithmic scale plots, concentrations below the limit of quantification will be 
set to missing.  
 
Plasma concentration data listings and individual plots will be presented using the Safety Set. Plasma 
concentration data summaries and mean plots will be presented using the PK Set and also the Safety Set 
if it differs from the PK Set. All plasma concentration data included in listings and summaries will be 
presented to three significant figures. 
 
11.4.2 Derived Plasma PK Parameters 
The following derived pharmacokinetic parameters of cytisine in plasma will be determined using 
WinNonlin Phoenix 6.4 from the individual concentration versus time profiles using standard non-

The terminal elimination rate constant (λz) will be determined by plotting the concentration data versus 
time on a semi-logarithmic scale.  The parameter will be estimated by linear least square regression 
analysis, using the last three (or more) non-zero concentrations.  The upper and the lower time points, 
as well as the number of time points, used for λz estimation will be reported. Values of λz, AUC0-∞, 
%AUC and t½ will not be reported for cases where λz cannot be reliably determined. 
 
AUC0-t will be calculated using the linear-up/log-down trapezoidal method. 
 
For the calculation of derived pharmacokinetic parameters, concentrations below the limit of 
quantification (BLQ) will be assigned a value of zero. In case of a deviation from the theoretical time, the 
actual time of blood sample will be used in the calculation of the derived pharmacokinetic parameters. 
Should the actual time be unavailable but a blood sample was taken, the nominal time point will be 
assigned. 
 
Derived pharmacokinetic parameters will be listed and summarised for each treatment. The descriptive 
statistics presented will be N, n, arithmetic mean, arithmetic standard deviation (SD), coefficient of 
variation (CV%), minimum, median, maximum and geometric mean (with the exception of Tmax). 
 
If no reliable PK parameter can be determined for more than a third of the subjects, only n, minimum 
and maximum values will be presented for that parameter and all other descriptive statistics will be 
omitted. 
 
Plasma PK parameter data listings will be presented using the Safety Set. Plasma PK data summaries will 
be presented using the PK Set and also the Safety Set if they differ. All PK parameter data included in 
listings and summaries will be presented to three significant figures with the exception of the CV% which 
will be presented to one decimal place. 
 
11.4.2.1 Statistical Analysis of Plasma PK Parameters 
 
Following logarithmic transformation, Cmax, AUC0-t, and AUC0-∞ values will be subjected to an analysis of 
variance (ANOVA) including fixed effects for sequence (treatment schedule), period, treatment and 
subject nested within sequence.  Point estimates and 90% confidence intervals (CI) will be constructed 
for the contrasts between fed and fasted states using the residual mean square error obtained from the 
ANOVA.  The point and interval estimates will be back-transformed to give estimates of the ratios of 
the geometric least squares means (LSmean) and corresponding 90% CI.  In addition, estimated 
geometric means will be presented.

A comparison of Tmax will be performed using the Wilcoxon Signed-Rank test.  In addition, the Hodges-
Lehmann estimate of the median difference in Tmax and 95% CI will be presented.  
 
The statistical analysis of the plasma PK parameters will be performed using the PK Set and also the 
Safety Set if they differ. Geometric LSmeans will be presented to three significant figures and the ratios 
and 90% CIs will be presented to 2 decimal places. 
 
11.4.3 Urine Concentration Data 
Urine PK samples will be collected for measurement of cytisine at the following time intervals during 
each study period: Pre-dose, 0-2h, 2-4h, 4-8h, 8-12h, 12-24h, 24-26h, 26-28h, 28-32h, 32-36h, 36-48h 
post-dose. 
 
Cytisine concentrations in urine will be listed and summarised for each using the descriptive statistics 
N, n, arithmetic mean, arithmetic standard deviation (SD), coefficient of variation (CV%), minimum, 
median and maximum.  
 
Urine concentrations will be listed using the Safety Set and summarised using the Urine Excretion Set. 
The summary may also be presented using the Safety Set if it differs from the Urine Excretion Set. All 
urine concentration data included in listings and summaries will be presented to three significant figures. 
 
11.4.4 Derived Urine PK Parameters 
The derived urine pharmacokinetic parameters, Ae and Ae% (individual and cumulative), will be 
determined from the individual concentration versus time data using SAS version 9.3. 
 
The derived urine PK parameter Ae will be calculated as: urine volume * urine cytisine concentration. 
Ae% will be derived as: 100*Ae/Dose (where dose is expressed in ng). The cumulative parameters 
(CumAe, CumAe%) are the sum of the individual values calculated for each time interval from 0h to 48h. 
Total Ae0-48h is defined as the total amount excreted from 0 h to 48 h. 
 
For the calculation of derived urine pharmacokinetic parameters, concentrations below the limit of 
quantification will be assigned a value of zero.  
 
The derived urine parameters Ae, Ae%, CumAe and CumAe% for each time interval will be listed and 
summarised with the urine cytsisine concentration data,  
 
The derived urine pharmacokinetic parameters Total Ae0-48h and Total Ae0-48h% will be listed and 
summarised separately using the descriptive statistics N, n, arithmetic mean, arithmetic standard 
deviation (SD), coefficient of variation (CV%), minimum, median, maximum and geometric mean. 
 
Urine PK parameter data listings will be presented using the Safety Set. Urine PK data summaries will be 
presented using the Urine Excretion Set and also the Safety Set should they differ. Urine PK parameter 
data included in listings and summaries will be presented to three significant figures with the exception 
of Ae% and CumAe% which will be presented to one decimal place.

Following logarithmic transformation, Total Ae0-48h values will be subjected to an analysis of variance 
(ANOVA) including fixed effects for sequence (treatment schedule), period, treatment and subject 
nested within sequence.  Point estimates and 90% confidence intervals (CI) will be constructed for the 
contrasts between fed and fasted states using the residual mean square error obtained from the

11.5 PD ANALYSES 
Not applicable. 
 
11.6 SAFETY ANALYSES 
11.6.1 Adverse Events 
All AEs will be coded using the MedDRA dictionary using the version specified in the Data Management 
Plan (DMP).  
All AEs, including those which occurred prior to the first dose of study drug, will be listed.  Only 
treatment emergent adverse events (TEAEs), i.e., existing conditions that worsen or events that occur 
during the course of the study after administration of IMP, will be included within the summary tables. 
AEs occurring post-dose on Period 1 up to immediately prior to dosing on Period 2 will be assigned to 
the corresponding Period 1 treatment. Similarly, any AEs occurring post-dose on Period 2 up to Post-
Study will be assigned to the corresponding Period 2 treatment. TEAEs will be summarised by treatment 
and overall.   
An overall summary of AEs will be produced including the number of TEAEs; the number and % of 
subjects reporting at least 1 TEAE, serious TEAE (where SAE is reported as ‘Yes’), TEAE leading to 
withdrawal from study drug (Action recorded as ‘Study Drug Discontinued’); the number and % of 
subjects reporting TEAEs by severity and relationship to study drug.  A subject with multiple occurrences 
of any AE is counted only once at the maximum level of severity or the highest association to study drug. 
The number of TEAEs and the number and % of subjects reporting at least one TEAE will be tabulated 
by system organ class (SOC) and preferred term (PT).  A subject reporting multiple episodes of a 
particular AE within a treatment period will only contribute one count towards the corresponding SOC 
and preferred term. The number of TEAEs and the number and % of subjects reporting at least one 
TEAE will also be tabulated by preferred term (PT), with the PTs sorted in descending order of 
frequency.  A subject reporting multiple episodes of a particular AE within a treatment period will only 
contribute one count towards the corresponding PT.

In addition, the number and % of subjects reporting TEAEs will be tabulated by maximum severity and 
strongest relationship to study drug.  For the summary of TEAEs by severity, if a subject has multiple 
events occurring within the same SOC or preferred term the event with the highest severity will be 
counted.  Similarly, for TEAEs by relationship to study drug, if a subject has multiple events occurring 
within the same SOC or PT, the event with the highest association to study drug will be counted. 
Data will be listed by treatment.  For any adverse event taken prior to first administration of study drug, 
treatment will be described as ‘Prior to Treatment’.  
Where there are only partial dates/times recorded for adverse events, adverse events will be assigned 
to treatment unless it can be ruled out based on the partial information.  
The derived variables, ‘Time from Dose’ and ‘Duration’ will be presented where full date and time are 
present. If partial dates are present for any parameter required in the calculation, then the variable will 
not be populated. The following will be used to calculate the variables: 
Duration: (Date/Time of Resolution-Date/Time of Onset) + 1 minute; 
 
Time from Dose: (Date/Time of Onset-Date/Time of Start of Dose). 
 
The following will be presented in listing format within the data summaries: 
 
Serious Adverse Events – If there are none present, the listing will be produced stating: ‘No subjects 
experienced any serious adverse events’. 
 
Adverse Events which Led to Withdrawal of Study Drug – If there are none present, the listing will be 
produced stating: ‘No subjects experienced any adverse events that led to withdrawal of study drug’. 
 
Adverse event data will be summarised and listed using the Safety Set.

Routine safety laboratory tests will be carried out at Screening and Day 5.  
The safety laboratory parameters required for this study are listed in section 9.1.1. 
 
Safety laboratory data listings will be presented in two ways: 
• 
Out of range values - any values that fall outside of the normal/alert ranges (presented in listing 
format within the data summaries) 
• 
All safety laboratory data (including physician’s review (Normal, Abnormal-NCS, Abnormal-CS)) 
with any out of range values flagged (presented within the data listings).  
Microscopy, virology, urine drugs of abuse and alcohol screen, pregnancy tests and other parameters 
will also be listed. 
 
If there are no further parameters databased other than those specified in section 9.1.1 then the ‘Other 
Laboratory Data’ listings should display, ‘No other laboratory parameters to report’. 
 
Laboratory data will be listed using the Safety Set.

11.6.3 Vital Signs 
Vital signs will be taken at Screening; Day 0; Day 1 at pre-dose and 2h post-dose (Period 1); Day 3 at 
pre-dose and 2h post-dose (Period 2); Day 5. 
Vital signs parameters (supine systolic and diastolic blood pressure and pulse rate and oral temperature) 
will be listed with any out of normal range values (see Appendix 16.1) flagged (flag ‘H’ or ‘L’ appended 
to relevant result). Descriptive statistics (N, n, mean, SD, minimum, median and maximum) of absolute 
and change from pre-dose to 2 h post-dose will be tabulated by treatment. 
 
Vital signs data will be listed and summarised using the Safety Set. 
 
11.6.4 Electrocardiogram 
11.6.4.1 12-Lead ECG 
12-lead ECGs will be performed in triplicate at Screening and prior to discharge on Day 5. 
12-lead ECG parameters (heart rate, PR interval, QRS width, QT interval and QTcF interval) will be 
listed with any out of normal range values (see Appendix 16.1) flagged (flag ‘H’ or ‘L’ appended to relevant 
result). The ECG results will also be assessed as either ‘normal’ or abnormal’ with comments on 
abnormal results also presented. 
 
12-lead ECG data will be listed using the Safety Set. 
 
 
11.7 OTHER DATA 
11.7.1 Prior and Concomitant Medications 
All medications will be coded using the WHO Drug Dictionary (version as specified in the DMP) and 
listed using the ATC Level 4 class, Preferred Term and verbatim text. A medication will be regarded as 
prior if it stops prior to administration of first treatment and will be assigned a treatment phase of ‘Prior 
to treatment’. A medication which starts prior to first treatment and continues after dosing and will be 
assigned a treatment phase of ‘Prior and ongoing’. Otherwise, treatment phase will be described as the 
treatment the medication started on. Where there are only partial dates/times recorded for medications, 
medications will be assigned to all treatments that cannot be ruled out based on the partial information.  
Prior and concomitant medications will be listed using the Safety Set. 
11.7.2 All Other Data 
All data will be listed using the Safety Set, including the following: Tobacco and Alcohol Use, Visit Dates, 
Medical History, Menstrual and Obstetric History, Physical Examination, Inclusion/Exclusion Criteria 
Failures, Bag Search and Cigarette Collection, Eligibility Check, Dose Administration and Additional 
Notes.
