Protocol Amendment 3 Rationale 
Amendment number: 
Amendment 3 
 
Rationale/background for changes: 
• 
In compliance with ICH requirements, the protocol mentions that all results will be 
presented in an integrated report at the end of the study. 
• 
Following re-development and re-validation of the anti-PD ELISA, a new cut-off 
was defined. 
• 
Reference to the GSK Biologicals’ Laval laboratory was removed, as this 
laboratory will not be used in the study. In addition, this laboratory is no longer 
part of GSK Biologicals’ laboratories. 
• 
Internal assay qualification procedures were revised and it was decided that the 
level of characterisation of the ELISA assays can be minimal (set-up level) for this 
study as immunogenicity data are descriptive. In consequence, the assays will be 
standardized but not qualified as stated in the original version.This change will not 
impact the validity of the results. 
• 
A tertiary endpoint was added as the presence of viral pathogens in sputum will be 
examined as part of microbiome analysis. 
• 
In order to see early effects of the vaccine on the microbiome, analysis on fresh 
sputum samples (culture results) will be done on all available data up to the data 
lock point of the interim analysis. 
• 
In order to have a first look whether or not the investigational vaccine has an 
impact on AECOPD, AECOPD analyses will be done up to the data lock point of 
the interim analysis. 
• 
Wording was added to clarify process for collection of sputum H. influenzae 
sweeps. 
• 
Wording was updated in order to be aligned with the Statistical Ananlysis Plan. 
• 
In addition, minor edits in other sections were made for clarification purposes.

SYNOPSIS 
Detailed Title 
A Phase II, randomised, observer-blind, placebo-controlled, 
multi-centre study to evaluate the safety, reactogenicity and 
immunogenicity of GSK Biologicals’ investigational vaccine 
GSK2838504A, when administered intramuscularly according 
to a 0, 2 month schedule to COPD patients aged 40 to 80 years 
 
Indication 
Active immunisation to reduce the frequency of Non-typeable 
Haemophilus influenzae (NTHi)-associated moderate and 
severe acute exacerbations (AECOPD) in COPD patients with a 
previous history of AECOPD 
 
Rationale for the 
study and study 
design 
Rationale for the study 
The purpose of this Phase II study, in which the investigational 
NTHi vaccine will be administered for the first time to 
moderate and severe COPD patients (i.e. GOLD grade 2 and 3), 
is to assess the vaccine’s safety, reactogenicity and 
immunogenicity in this population, and to evaluate in an 
exploratory manner whether an NTHi vaccine can reduce the 
frequency of moderate and severe AECOPD associated with 
NTHi. Placebo will be used as a control. Both the 
investigational NTHi vaccine and the placebo will be given on 
top of the standard of care. 
 
Rationale for the study design 
• 
Scheduled study visits, during which the effect of 
immunisation against NTHi will be evaluated, will take 
place at pre-defined timepoints. In addition, ad-hoc 
AECOPD-driven study visit(s) and/ or phone contact(s) 
will take place for each AECOPD occurring from first 
vaccination up to study conclusion. Besides evaluating the 
effect of vaccination against NTHi on AECOPD, the 
information obtained during these AECOPD-driven study 
contacts will help refining the case definition of AECOPD 
and of NTHi-associated AECOPD. 
• 
As the investigational vaccine will be administered for the 
first time to moderate and severe COPD patients, an 
internal Safety Review Committee (iSRC) will be 
appointed next to the existing project’s Safety Review 
Team (SRT) and safety holding rules have been defined. 
Administration vaccine Dose 1 will follow a staggered 
design, starting with vaccination of GOLD 2 subjects only. 
Administration of vaccine Dose 1 to GOLD 3 subjects will 
depend on the favourable outcome of an iSRC evaluation 
of safety data up to at least day 6 after vaccination from

about 20 GOLD 2 subjects (i.e. approximately 10 subjects/ 
group). 
In addition, starting administration of vaccine Dose 2 will 
for each GOLD grade depend on the favourable outcome 
of an iSRC evaluation of all available safety data. 
 
Rationale for the use of placebo 
There is currently no established vaccine with recognised 
efficacy in reducing the frequency of NTHi-associated 
AECOPD. Placebo will therefore be used as a control. 
 
Objectives 
Primary 
• 
To describe the safety and reactogenicity of the 
investigational vaccine. 
 
Secondary 
• 
To describe the humoral and cellular immunogenicity of 
the investigational vaccine. 
 
Tertiary 
• 
To explore the impact of the investigational vaccine on 
AECOPD. 
• 
To explore the impact of the investigational vaccine on 
NTHi presence in sputum. 
• 
To explore the impact of the investigational vaccine on 
health-related quality of life (HRQOL). 
• 
To explore the impact of the investigational vaccine on 
lung function. 
• 
To explore the impact of the investigational NTHi vaccine 
on exercise capacity. 
• 
To describe selected biomarkers in stable COPD and 
during AECOPD. 
• 
To collect blood and sputum samples for assay 
development, for disease diagnostic purpose, for lung 
microbiome analysis and/ or for additional evaluation of 
the immune responses to the investigational vaccine and to 
other potential pathogens involved in AECOPD.

GLOSSARY OF TERMS 
Adequate contraception: 
Adequate contraception is defined as a contraceptive 
method with failure rate of less than 1% per year when 
used consistently and correctly and when applicable, in 
accordance with the product label for example: 
• 
Abstinence from penile-vaginal intercourse, when 
this is their preferred and usual lifestyle. 
• 
Oral contraceptives, either combined or progestogen 
alone. 
• 
Injectable progestogen. 
• 
Implants of etenogestrel or levonorgestrel. 
• 
Estrogenic vaginal ring. 
• 
Percutaneous contraceptive patches. 
• 
Intrauterine device or intrauterine system. 
• 
Male partner sterilisation prior to the female 
subject’s entry into the study, and this male is the 
sole partner for that subject. 
The information on the male sterility can come from 
the site personnel’s review of the subject’s medical 
records; or interview with the subject on her medical 
history. 
• 
Male condom combined with a vaginal spermicide 
(foam, gel, film, cream or suppository). 
• 
Male condom combined with a female diaphragm, 
either with or without a vaginal spermicide (foam, 
gel, film, cream, or suppository). 
Adequate contraception does not apply to subjects of 
child bearing potential with same sex partners, when this 
is their preferred and usual lifestyle. 
 
Adverse event: 
Any untoward medical occurrence in a patient or clinical 
investigation subject, temporally associated with the use 
of a medicinal product, whether or not considered related 
to the medicinal product. 
An adverse event (AE) can therefore be any unfavourable 
and unintended sign (including an abnormal laboratory 
finding), symptom, or disease (new or exacerbated) 
temporally associated with the use of a medicinal product. 
For marketed medicinal products, this also includes 
failure to produce expected benefits (i.e. lack of efficacy), 
abuse or misuse.

Alcoholism: 
Alcoholism, also known as dependency on alcohol or 
alcohol addiction, is a chronic disease. The signs and 
symptoms of alcoholism include: 
• 
A strong craving for alcohol. 
• 
Continued use despite repeated physical, 
psychological, or interpersonal problems. 
• 
The inability to limit drinking. 
Blinding: 
A procedure in which one or more parties to the trial are 
kept unaware of the treatment assignment in order to 
reduce the risk of biased study outcomes. The level of 
blinding is maintained throughout the conduct of the trial, 
and only when the data are cleaned to an acceptable level 
of quality will appropriate personnel be unblinded or 
when required in case of a serious adverse event. In an 
observer-blind study, the subject and the site and sponsor 
personnel involved in the clinical evaluation of the 
subjects are blinded while other study personnel may be 
aware of the treatment assignment (see Section 6.3 for 
details on observer-blinded studies). 
 
Current smoker: 
A person who is currently smoking or who stopped 
smoking within the past 6 months. 
 
Eligible: 
Qualified for enrolment into the study based upon strict 
adherence to inclusion/exclusion criteria. 
 
Epoch: 
An epoch is a self-contained set of consecutive 
timepoints or a single timepoint from a single protocol. 
Self-contained means that data collected for all subjects 
at all timepoints within that epoch allows to draw a 
complete conclusion to define or precise the targeted 
label of the product. Typical examples of epochs are 
primary vaccinations, boosters, yearly immunogenicity 
follow-ups, and surveillance periods for efficacy or 
safety. 
 
eTrack: 
GSK’s tracking tool for clinical trials. 
 
Evaluable: 
Meeting all eligibility criteria, complying with the 
procedures defined in the protocol, and, therefore, 
included in the according-to-protocol (ATP) analysis (see 
Sections 7.6.2, 7.6.3 and 11.5 for details on criteria for 
evaluability). 
 
Former smoker: 
A person who stopped smoking for at least 6 months.

Immunological correlate 
of protection: 
 
 
Investigational 
vaccine/product: 
(Synonym of 
Investigational Medicinal 
Product) 
The defined humoral antibody response above which 
there is a high likelihood of protection in the absence of 
any host factors that might increase susceptibility to the 
infectious agent. 
 
A pharmaceutical form of an active ingredient or placebo 
being tested or used as a reference in a clinical trial, 
including a product with a marketing authorisation when 
used in a way different from the approved form, or when 
used for an unapproved indication, or when used to gain 
further information about an approved use. 
 
Menopause: 
Menopause is the age associated with complete cessation 
of menstrual cycles, menses, and implies the loss of 
reproductive potential by ovarian failure. A practical 
definition accepts menopause after 1 year without menses 
with an appropriate clinical profile at the appropriate age 
e.g. > 45 years. 
 
Pack-years of smoking: 
Pack-years is a quantification of cigarette smoking, a way 
to measure the total amount a person has smoked in the 
course of his/ her lifetime. The number of pack-years is 
calculated as follows: 
(average number of cigarettes smoked per day x 
number of years smoked)/ 20 
E.g. a smoking history of 10 pack-years means having 
smoked 20 cigarettes per day for 10 years, or having 
smoked 10 cigarettes per day for 20 years. 
Note: For the purpose of this study, pipe and/or cigar use 
should not be used to calculate pack year history. 
 
Potential Immune- 
Mediated Disease: 
 
 
Primary completion 
date: 
Potential immune-mediated diseases (pIMDs) are a subset 
of AEs that include autoimmune diseases and other 
inflammatory and/or neurologic disorders of interest 
which may or may not have an autoimmune aetiology.

INTRODUCTION 
1.1. 
Background 
1.1.1. 
Chronic obstructive pulmonary disease and acute exacerbations 
 
Chronic obstructive pulmonary disease (COPD) is a disease characterised by persistent 
airflow obstruction which is not fully reversible and which is usually progressive in the 
long term. The airflow limitation in COPD patients can be classified into GOLD grades 
as shown in Table 1 [GOLD, 2013]. 
 
Table 1 
Classification of severity of airflow limitation in COPD (based on 
post-bronchodilator FEV1) 
 
GOLD grade 
In patients with FEV1/ FVC < 0.70: 
GOLD 1: Mild 
FEV1 ≥ 80% predicted 
GOLD 2: Moderate 
50% ≤ FEV1 < 80% predicted 
GOLD 3: Severe 
30% ≤ FEV1 < 50% predicted 
GOLD 4: Very Severe 
FEV1 < 30% predicted 
The airflow limitation in COPD is associated with an enhanced and chronic inflammatory 
response to noxious particles and gases in the airways and the lungs. COPD results from 
a gene-environment interaction. The most important environmental risk factor for COPD 
is tobacco smoking, even though other factors, such as occupational exposure, may also 
contribute to the development of the disease [GOLD, 2013]. The prevalence and burden 
of COPD are projected to increase in the coming decades due to continued exposure to 
risk factors and the changing age structure of the world’s population. 
 
The morbidity and mortality of COPD is substantially contributed to by acute 
exacerbation of COPD (AECOPD), which are events during which the patient’s 
respiratory symptoms acutely worsen beyond normal day-to-day variations and which 
require a change in maintenance treatment. Higher exacerbation rates have been related 
to a faster decline in lung function and are known to have a negative effect on the 
patient’s quality of life. Moreover, frequent exacerbations are associated with significant 
mortality, particularly if they require hospitalisation. Between 40 - 60% of medical 
expenditure for COPD is a direct consequence of AECOPD Cazzola, 2008. 
The lungs are known to be colonised with different strains of bacteria [Erb-Downward, 
2011]. In COPD patients, acquisition of new bacterial strains is believed to be an 
important cause of AECOPD [Sethi, 2002]. Although estimates vary widely, Non- 
typeable Haemophilus influenzae (NTHi) appears to be the main bacterial pathogen 
associated with AECOPD (11-38%), followed by Moraxella catarrhalis (M. catarrhalis) 
(3-25%) and Streptococcus pneumoniae (S. pneumoniae) (4-9%) [Alamoudi, 2007; 
Bandi, 2003; Hutchinson, 2007; Ko, 2007; Larsen, 2009; Murphy, 2005; Papi, 2006; 
Sethi, 2002; Sethi, 2008].

Reducing the frequency and severity of AECOPD is one of the main goals of COPD 
maintenance treatment. The severity of AECOPD can be graded according to the 
intensity of medical intervention required (see Table 2) [Wedzicha, 2007. 
Table 2 
Classification of severity of AECOPD 
 
Grade 
Intensity of medical intervention 
Mild 
Can be controlled with an increase in dosage of regular medications 
Moderate 
Requires treatment with systemic corticosteroids and/ or antibiotics 
Severe 
Requires hospitalisation 
 
1.1.2. 
Current management of AECOPD 
 
A wide range of pharmacologic (such as inhaled corticosteroids, bronchodilators, 
phosphodiesterase inhibitors, theophyllines, long-term antibiotics and mucolytics) and 
non-pharmacologic (such as lung volume reduction surgery, home oxygen, ventilatory 
support and pulmonary rehabilitation) interventions exist to reduce AECOPD and 
hospitalisation rates. However, a need for further novel interventions remains because 
current approaches are not completely effective, even when targeted and used optimally. 
 
No vaccine is currently indicated for the prevention of AECOPD, even though flu and 
pneumococcal vaccines are routinely recommended to COPD patients. The availability of 
a vaccine for the prevention of bacterial AECOPD could contribute significantly to the 
management of COPD. 
 
1.1.3. 
GSK Biologicals’ investigational NTHi vaccine 
 
GlaxoSmithKline (GSK) Biologicals is developing a vaccine targeting NTHi in order to 
reduce the frequency of moderate and severe AECOPD in COPD patients with a previous 
history of AECOPD. The vaccine is intended to be administered on top of standard of 
care. The selected investigational vaccine consists out of 3 conserved surface proteins 
(protein D [PD, protein E [PE and PilA; the latter 2 are included in the vaccine as a 
fusion protein named PE-PilA) adjuvanted with GSK’s proprietary Adjuvant System 
AS01E. 
Refer to the current Investigator Brochure and its supplement for information regarding 
the pre-clinical and clinical studies and the potential risks and benefits of the 
investigational NTHi vaccine. 
 
1.2. 
Rationale for the study and study design 
1.2.1. 
Rationale for the study 
 
The purpose of this Phase II study, in which the investigational NTHi vaccine will be 
administered for the first time to moderate and severe COPD patients, is to assess the 
vaccine’s safety, reactogenicity and immunogenicity in this population, and to evaluate in 
an exploratory manner whether an NTHi vaccine can reduce the frequency of moderate

and severe AECOPD associated with NTHi. Placebo will be used as a control. Both the 
investigational NTHi vaccine and the placebo will be given on top of the standard of care. 
 
1.2.2. 
Rationale for the study design 
 
1.2.2.1. 
Scheduled study visits and AECOPD-driven study contacts 
 
Scheduled study visits, during which the effect of immunisation against NTHi will be 
evaluated, will take place at pre-defined timepoints (see Figure 1). 
 
In addition to the scheduled study visits, ad-hoc AECOPD-driven study visit(s) and/ or 
phone contact(s) will take place for each AECOPD occurring from first vaccination up 
to study conclusion: 
• 
An AECOPD visit will be scheduled as soon as possible after the onset of AECOPD 
symptoms (maximum 96 hours after and, if applicable, preferably before starting 
treatment with antibiotics). 
• 
Follow-up phone call(s) and/ or visits will take place to determine the end of the 
AECOPD. These contacts will take place at least every 2 weeks, until the AECOPD 
has resolved. 
Besides evaluating the effect of vaccination against NTHi on AECOPD, the information 
obtained during these AECOPD-driven study contacts will help refining the case 
definition of AECOPD and of NTHi-associated AECOPD. 
 
1.2.2.2. 
Safety overview and staggered vaccination 
 
As the investigational vaccine will be administered for the first time to moderate and 
severe COPD patients, an internal Safety Review Committee (iSRC) will be appointed 
next to the existing project’s Safety Review Team (SRT) and safety holding rules have 
been defined. 
 
The iSRC will conduct unblinded reviews of all available safety data from the present 
study, including data on AECOPD (frequency, intensity and duration). Each safety 
evaluation by the iSRC will be preceded by a blinded safety review of the same safety 
data by the SRT. 
 
Administration of vaccine Dose 1 will follow a staggered design, starting with 
vaccination of GOLD 2 subjects only. Administration of vaccine Dose 1 to GOLD 3 
subjects will depend on the favourable outcome of an iSRC evaluation of safety data up 
to at least day 6 after vaccination from about 20 GOLD 2 subjects (i.e. approximately 10 
subjects/ group). 
 
In addition, starting administration of vaccine Dose 2 will for each GOLD grade depend 
on the favourable outcome of an iSRC evaluation of all available safety data. 
 
Refer to Section 9.10 for more detailed information on safety monitoring and escalation 
of safety signals to GSK Biologicals’ Vaccine Monitoring Board (VSMB).

1.2.3. 
Rationale for the use of placebo 
 
There is currently no established vaccine with recognised efficacy in reducing the 
frequency of NTHi-associated AECOPD. Placebo will therefore be used as a control. 
 
1.3. 
Benefit: Risk assessment 
Please refer to the current IB for the summary of potential risks and benefits of the NTHi 
investigational vaccine. 
 
The following section outlines the risk assessment and mitigation strategy for the study 
protocol: 
 
1.3.1. 
Risk Assessment 
 
Important 
Potential/Identified Risk 
Data/Rationale for Risk 
Mitigation Strategy 
NTHi investigational vaccine 
Theoretical risk of acquiring 
a vaccine-induced 
autoimmune disease after 
vaccination 
No confirmed signals related to 
this potential risk have been 
identified during the preclinical 
and clinical programs so far 
(data from two studies using 
NTHi vaccines: NTHI-002 (non- 
adjuvanted formulations) and 
NTHI-003 (adjuvanted and 
non-adjuvanted formulations). 
Close monitoring of potential 
immune-mediated diseases in 
clinical development programs 
using adjuvants systems. The 
potential risk of events of 
possible autoimmune aetiology 
to occur is mentioned in the 
Informed Consent Form (ICF). 
 
1.3.2. 
Benefit Assessment 
 
Benefits considerations include: 
 
• 
Contribution to the process of developing of a vaccine against AECOPD. 
• 
Medical evaluations/assessments associated with this study (i.e. physical 
examination, blood testing [haematology and biochemistry data], spirometry). 
 
1.3.3. 
Overall Benefit : Risk Conclusion 
 
Taking into account the measures taken to minimize risks to subjects participating in this 
study, the potential and/or known risks identified in association with the candidate NTHi 
vaccine are justified by the anticipated benefits that may be afforded to patients for the 
prevention of AECOPD.

4. 
AECOPD 
4.1. 
Detection of AECOPD 
Occurrence of each potential AECOPD will be monitored by means of electronic Diary 
Cards which the subject will use to record his/ her morning symptoms on a daily basis. 
The electronic Diary Cards will be programmed as to detect each potential AECOPD as 
follows (based on the Anthonisen criteria [Anthonisen, 1987]): 
• 
Worsening of two or more of the following major symptoms for at least two 
consecutive days: dyspnoea, sputum volume, sputum purulence (colour), OR 
• 
Worsening of any one major symptom together with any one of the following minor 
symptoms for at least two consecutive days: sore throat, colds (nasal discharge and/ 
or nasal congestion), fever (oral temperature  37.5°C) without other cause, 
increased cough, increased wheeze. 
Note that: 
• 
The same two symptoms do not have to be present on both days as long as at least 
one major symptom is present on both days. 
• 
Any symptom occurring on at least 5 consecutive days prior to a potential 
exacerbation will be discounted from the symptoms that define an exacerbation. 
 
Each time a potential AECOPD is detected via the electronic Diary Card, the device will 
alert the subject to contact the study site, and at the same time an alert will be sent to the 
site so that the site staff contacts the subject to check whether an AECOPD visit is 
warranted. In addition, the site should pro-actively follow-up all data received via the 
electronic Diary Card and contact the subject whenever deemed necessary. 
During the contact with the subject, the site will determine whether the subject might 
actually be experiencing an AECOPD (e.g. notifications that can be explained solely by 
increased physical activity will not be considered). 
For all potential AECOPD detected between first vaccination and study conclusion: 
• 
If the site concludes that the subject is not experiencing an AECOPD, this should be 
documented/ reported. 
• 
If the site concludes that the subject may be experiencing an AECOPD, an AECOPD 
visit will be scheduled as soon as possible after the onset of AECOPD symptoms as 
recorded in the electronic Diary Card or confirmed by the subject (maximum 96 
hours after and, if applicable, preferably before starting treatment with antibiotics) *. 
* In case of AECOPD occurring before Visit 1, subjects should be treated outside the 
study according to standard practice. These subjects can only continue in the study if 
the entire Screening Visit is repeated after they are stable for at least 30 days.

During the AECOPD visit, the investigator will confirm the occurrence of the AECOPD 
based on clinical and medical judgement, and will record its date of onset. The end date 
of the AECOPD and its severity will be determined/ confirmed during follow-up phone 
call(s) and/ or study visit(s), which will take place at least every 2 weeks until the 
AECOPD has resolved. 
 
4.1.1. 
Date of onset and end date of AECOPD 
 
The date of onset is the first day (of at least 2 consecutive days) of worsening symptoms 
of COPD. 
 
The end date should be based on when the investigator determines that the AECOPD 
symptoms have resolved. In determining this end date, consideration should be given to 
symptoms recorded in the electronic Diary Card and subject assessment. 
 
Both start and end date of each confirmed AECOPD occurring from Visit 1 to study 
conclusion will be recorded in the eCRF. 
 
4.1.2. 
Guideline for assessing AECOPD that increase in severity 
 
If an exacerbation starts off as mild, but becomes moderate or severe or starts off as 
moderate and becomes severe, the exacerbation should be captured as one exacerbation 
and classified by its highest level of severity. 
 
4.2. 
Treatment of AECOPD 
As the treatment given for an AECOPD might have an impact on relapse/ recurrence or 
time until the next AECOPD, guidance on how to preferably treat AECOPD is provided 
in Sections 4.2.1 and 4.2.2. 
 
4.2.1. 
Guidelines for treatment with antibiotics 
 
If there is evidence of respiratory infection that in the opinion of the investigator warrants 
the need for antibiotics the following guidelines are recommended: 
• 
It is suggested to use an aminopenicillin, a macrolide or a tetracycline as initial 
empirical treatment for 7 days (taking into account guidance issued locally by 
infectious disease specialists or other relevant medical function). 
 
• 
If first line antibiotic treatment fails and additional antibiotics are used, the total 
duration of antibiotic treatment should ideally be  30 days. 
4.2.2. 
Guidelines for treatment with systemic corticosteroids 
 
If in the opinion of the investigator the AECOPD is severe enough to warrant the need for 
systemic corticosteroids (with or without antibiotics) the following guidelines are 
recommended: 
• 
It is suggested to use prednisolone 30 mg as initial empirical treatment for 7 days. 
• 
The duration of treatment with systemic corticosteroids should ideally be  14 days.

4.3. 
Case definition NTHi-associated AECOPD 
The case definition of NTHi-associated AECOPD has not been established yet. 
NTHi-association will be determined using sputum samples taken during AECOPD and 
could for instance be based on the presence of (NT)Hi (any), on (NT)Hi bacterial load or 
on the acquisition of a new strain of NTHi. The final case definition to be used in the 
analysis of this study will be built based on the data obtained in the on-going GSK 
Biologicals’ study EPI-HIP-001 (114378) “An epidemiology study to assess the 
contribution of bacterial and viral pathogens to AECOPD in adults and elderly between 
40 and 85 years of age in the UK”. 
 
An endpoint assessment/ adjudication committee may be appointed to review AECOPD.

the drug depot. 
 
6.2.2.2. 
Treatment allocation to the subject 
 
The treatment numbers will be allocated by dose. 
 
6.2.2.2.1.       Study group and treatment number allocation 
 
The target will be to enrol approximately 140 eligible subjects who will be randomly 
assigned to the 2 study groups in a (1:1) ratio (approximately 70 subjects in each group). 
 
Allocation of a subject to a study group at the investigator site will be performed using a 
centralised randomisation system on the internet (SBIR). The randomisation algorithm 
will use a minimisation procedure accounting for age (40 - 59 years or 60 - 80 years), 
number of moderate/ severe AECOPD in the previous year (< 2 or  2) and GOLD grade 
(GOLD 2 or GOLD 3). All factors will have equal weight in the minimisation algorithm. 
 
At Visit 1, before administration of vaccine Dose 1 to eligible subjects who signed and 
dated the ICF at the Screening Visit, the dedicated site staff will access SBIR. Upon 
providing the subject’s age category (40 - 59 years or 60 - 80 years), number of 
moderate/ severe AECOPD in the previous year and his/ her GOLD grade, the 
randomisation system will determine the study group and will provide the treatment 
number to be used for the first dose. 
 
The number of each administered treatment must be recorded in the eCRF on the Vaccine 
Administration screen. 
 
When SBIR is not available, refer to the SBIR user guide or the SPM for specific 
instructions. 
 
6.2.2.2.2.       Treatment number allocation for subsequent doses 
 
For each dose subsequent to the first dose, the dedicated study staff will access SBIR. 
Upon providing the subject identification number, the system will provide a treatment 
number consistent with the allocated study group. 
 
The number of each administered treatment must be recorded in the eCRF on the Vaccine 
Administration screen. 
 
When SBIR is not available, refer to the SBIR user guide or the SPM for specific 
instructions. 
 
6.3. 
Method of blinding 
As the vaccines in this study are of different appearance and the investigational NTHi 
vaccine will have to be reconstituted whereas the placebo does not, double-blinding is not 
feasible and data will be collected in an observer-blind manner. By observer-blind, it is 
meant that during the course of the study, the vaccine recipient and those responsible for

the evaluation of any study endpoint will all be unaware of which vaccine was 
administered. 
 
Study site 
Each study site is responsible for having a blinding plan. To work in an observer-blind 
manner, vaccine preparation and administration will be done by authorised medical 
personnel who will not participate in any of the study clinical evaluation assays. Two 
teams of study personnel will hence be set up: 
• 
A team of unblinded personnel (responsible for the preparation and the 
administration of the vaccines) 
• 
A team of blinded personnel (responsible for the clinical evaluation of the subjects). 
Refer to the SPM for guidance on vaccine preparation and administration while 
maintaining the blind. 
 
Laboratory testing 
The laboratory in charge of the laboratory testing will be blinded to the treatment, and 
codes will be used to link the subject and study (without any link to the treatment 
attributed to the subject) to each sample. 
 
Analysis 
An analysis of immunogenicity and safety data up to Visit 6 (Day 90) will be done on as 
cleaned as possible data (please refer to Section 11.14.1 for more information). At this 
point, the GSK statistician (or delegates) of the project will be unblinded (i.e. will have 
access to the individual subject treatment assignment). The remaining GSK study 
personnel (excluding the iSRC members and their back-ups) will remain blinded (i.e. will 
not have access to the individual subject treatment assignment) until study end. It is 
possible however, due to the limited sample size, that unblinding occurs for a few 
subjects having a specific adverse event (AE) or serious adverse event (SAE) (e.g. an AE/ 
SAE occurring only in a single group). Therefore anyone having access to the analysis up 
to Day 90 could become unblinded regarding those specific cases. 
 
6.4. 
General study aspects 
Supplementary study conduct information not mandated to be present in this protocol is 
provided in the accompanying SPM. The SPM provides the investigator and the site 
personnel with administrative and detailed technical information that does not impact the 
safety of the subjects. 
 
Refer to Section 9.10 for more information on safety monitoring and holding rules.

List of study procedures during AECOPD-driven study visits and 
phone contacts 
 
In addition to the scheduled study visits, ad-hoc AECOPD-driven study contacts will take 
place for each AECOPD occurring from first vaccination up to study conclusion. The 
procedures to be performed during these contacts are listed in Table 8. 
 
In case of AECOPD occurring before Visit 1, subjects should be treated outside the study 
according to standard practice. These subjects can only continue in the study if the entire 
Screening Visit is repeated after they are stable for at least 30 days.

6.5.3. 
Concurrence of AECOPD-driven study visits and scheduled 
study visits 
 
If an AECOPD occurs at the time of a scheduled study visit, it should be handled and 
recorded as an AECOPD visit, with all relevant study procedures performed and, if 
possible, the scheduled visit should be re-scheduled to a later date within the time 
window specified in the protocol. In consultation with GSK, only Visit 8 (Day 270) and 
Visit 10 (Day 450) may exceptionally be conducted outside of the allowed interval if 
necessary. 
 
If an end of AECOPD contact occurs around the same time of a scheduled study visit, 
they can be combined into a single visit with the study procedures relevant to both visit 
types performed. In this case, both visit types will need to be recorded in the eCRF 
separately.

2 Subjects will not be eligible for inclusion in the according-to-protocol (ATP) cohort for analysis of immunogenicity if 
they make the study visit outside this interval. 
3 Subjects will not be eligible for inclusion in the ATP cohort for analysis of persistence of immunogenicity if they make 
the study visit outside this interval. 
4 AECOPD visits will be scheduled as soon as possible after the onset of AECOPD symptoms as recorded in the 
electronic Diary Card or confirmed by the subject (maximum 96 hours after and, if applicable, preferably before starting 
treatment with antibiotics). 
5 Scheduled study visits should not take place within 7 days of an AECOPD visit. If an AECOPD occurs at the time of a 
scheduled study visit so that this is not adhered to, the scheduled visit should be re-scheduled to a later date within the 
time window specified. In consultation with GSK, only Visit 10 (Day 450) may exceptionally be conducted outside of the 
allowed interval if necessary.

6.6.8. 
Smoking exposure history 
 
The subject should self-complete the smoking history questionnaire (which is a shortened 
version of the ATS-DLD-78A questionnaire), which will be provided electronically via a 
SITEpro tablet. The subject will have to provide information about his/ her smoking 
history, including duration (number of years) and number of cigarettes smoked. 
 
From the information obtained via the questionnaire, calculation of the pack-years will be 
done. 
 
The data will be directly transferred from the provider to GSK Biologicals. 
 
Refer to the SPM for details and guidance on the smoking exposure history questionnaire.

glossary of terms for the definitions of current and former smoker. 
 
6.6.10. 
Physical examination 
 
At Screening, perform a complete physical examination of the subject, including vital 
signs after at least 10 minutes of rest (systolic/ diastolic blood pressure, heart rate, 
respiratory rate). Record collected information in the eCRF. 
 
Physical examination at each study visit subsequent to the Screening Visit will be 
performed only if deemed necessary by the investigator or delegate. 
 
Treatment of any abnormality observed during a physical examination has to be 
performed according to local medical practice outside this study or by referral to an 
appropriate health care provider. 
 
6.6.11. 
Measure/ record height and weight 
 
Measure height and weight of the subject and record the data in the ‘Physical 
examination’ section of the eCRF. 
 
6.6.12. 
Pre- and post-bronchodilator spirometry 
 
Pre- and post-bronchodilator spirometry should be performed during specified study 
visits as detailed in Table 7. 
 
Only certified study staff can perform spirometry assessment. 
 
Spirometry will be performed using techniques that meet published standards [NICE, 
2010 and following all safety requirements. 
The data will be directly transferred from the provider to GSK Biologicals.

to local medical practice outside this study or by referral to an appropriate health care 
provider. 
 
6.6.13. 
Chest X-ray 
 
Screening 
A posterior to anterior (PA) chest X-ray must be performed at Screening if no chest 
X-ray/ CT scan is available within the last 3 months. 
 
Subjects with evidence of clinically significant abnormalities not believed to be due to 
the presence of COPD will not be eligible for study participation. 
 
AECOPD visit 
A chest X-ray should be performed at the AECOPD visit if it is clinically indicated to 
exclude another cause of worsening of symptoms (e.g. pneumonia). 
 
All cases of pneumonia (including all signs and symptoms assessed to confirm 
pneumonia) should be documented in the eCRF. 
 
6.6.14. 
Urine pregnancy test 
 
Female subjects of childbearing potential are to have a urine pregnancy test at Screening 
and prior to any study vaccine administration. The study vaccine may only be 
administered if the pregnancy test is negative. Note: The urine pregnancy test must be 
performed even if the subject is menstruating at the time of the study visit. 
 
6.6.15. 
Sampling 
 
Refer to the Module on Biospecimen Management in the SPM and to the central 
laboratory manual for detailed instructions for the collection, handling and processing of 
the samples. 
 
6.6.15.1. 
Blood samples 
 
Blood samples will be taken during specified study visits (scheduled visits and 
exacerbation visits) as detailed in Table 7 and Table 8. 
 
Blood samples for safety assessment 
For scheduled visits: a volume of approximately 5.5 mL of whole blood should be drawn 
from all subjects at each pre-defined timepoint (Table 10) and will be split and processed 
as follows: 
• 
Approximately 2 mL of whole blood will be collected for haematology assessment. 
These samples will not be processed. They should be kept at room temperature and 
shipped on the day of collection.

Paper Diary Cards for recording of vaccine reactogenicity 
• 
After each vaccination, 2 paper Diary Cards for recording of vaccine reactogenicity 
will be distributed to the subject: 
 
A 1st Diary Card will be distributed on the day of vaccination for daily 
recording of body temperature and of any solicited and unsolicited AEs from 
day 0 to 6 after each vaccination. The subject will be instructed to return the 
completed Diary Card to the study site at the next study visit (7 days post- 
vaccination). 
 
A 2nd Diary Card will be distributed at the 7 day post-vaccination visit for 
recording of any unsolicited AEs from day 7 to 29 after each vaccination. The 
subject will be instructed to return the completed Diary Card to the study site at 
the next study visit (30 days post-vaccination). 
• 
Collect and verify completed Diary Cards during discussion with the subject during 
each 7-days post-vaccination visit and during each 30-day post-vaccination visit. 
• 
Any unreturned Diary Cards will be sought from the subject through telephone 
call(s) or any other convenient procedure. 
• 
The investigator will transcribe the collected information into the eCRF. 
Refer to the SPM for more details and guidance on Diary Card completion 
guidelines. 
 
6.6.21.

Paper Diary Card for recording of medication 
At the Screening Visit, a paper medications Diary Card will be distributed to the subject: 
• 
All vaccinations and medications (except for vitamins and dietary supplements) 
administered throughout the study period (including dose, unit, frequency and reason 
for use) should be recorded on this medication Diary Card. 
• 
Subjects will be advised to bring all medications they are currently using during each 
of the study visits (including AECOPD-driven visits). At Screening, the medication 
Diary Card will be completed at the study site, with the help of the study staff. After 
that, the subject should update the Diary Card each time additional medication was 
taken, or a change to his/ her standard treatment was made. 
• 
The medications Diary Cards will be reviewed with the subject at each study visit 
and a copy will be retained at the site. 
• 
The investigator will transcribe the collected information into the eCRF. 
Refer to the SPM for more details and guidance on Diary Card completion 
guidelines.

Train subjects on the use of electronic Diary Card and assign 
electronic Diary Card to subject 
 
During the Screening Visit, subjects will be trained on how to use their electronic Diary 
Card. 
 
At Visit 1, the investigator should evaluate whether or not the subject will be able to 
comply with the daily completion of the electronic Diary Card throughout the study 
(based on electronic Diary Card completion between Screening and Visit 1). 
 
Compliance with electronic Diary Card completion implies that subject learns how to 
translate his/ her respiratory symptoms in answers to the questions as well as acquiring 
the technical expertise to use the device. Refer to the SPM for recommendations on what 
is considered adequate compliance by Visit 1. 
 
Subjects for whom the investigator thinks they will not comply will be considered 
Screening failures. 
 
During the learning period in-between Screening and Visit 1, the site staff will follow 
electronic Diary Card completion closely and should provide timely input/guidance to 
ensure that the subject reaches the targeted learning curve. 
 
In addition, site staff will pro-actively monitor electronic Diary Card compliance 
throughout the study and provide the necessary input to maintain compliance. 
 
6.6.24. 
6-minute walk test 
 
The subject should perform the supervised, standardised 6MWT at specified study visits

Under the following circumstances, additional testing on the samples may be performed 
by GSK Biologicals outside the scope of this protocol: 
• 
Collected samples may be used in other assays, for test improvement or development 
of analytical methods related to the study vaccine and its constituents or the disease 
under study. 
• 
Collected samples may be used for purposes related to the quality assurance of data 
generated linked to the study vaccine or the disease under study, such as for 
maintenance of assays described in this protocol and comparison between analytical 
methods and/ or laboratories. 
 
Information on further investigations and their rationale can be obtained from GSK 
Biologicals. 
 
Any sample testing will be done in line with the consent of the individual subject. 
 
Refer also to the Investigator Agreement, where it is noted that the investigator cannot 
perform any other biological assays except those described in the protocol or its 
amendment(s). 
 
Collected samples will be stored for a maximum of 20 years (counting from when the last 
subject performed the last study visit), unless local rules, regulations or guidelines require 
different timeframes or different procedures, which will then be in line with the subject 
consent. These extra requirements need to be communicated formally to and discussed 
and agreed with GSK Biologicals. 
 
6.7.1. 
Use of specified study materials 
 
When materials are provided by GSK Biologicals or by the central laboratory, it is 
MANDATORY that all clinical samples (including serum samples) be collected and 
stored exclusively using those materials in the appropriate manner. The use of other 
materials could result in the exclusion of the subject from the according-to-protocol 
(ATP) analysis (See Section 11.5 for the definition of study cohorts/ data sets to be 
analysed). The investigator must ensure that his/ her personnel and the laboratory(ies) 
under his/her supervision comply with this requirement. However, when GSK 
Biologicals does not provide material for collecting and storing clinical samples, 
appropriate materials from the investigator’s site must be used. Refer to the Module on 
Clinical Trial Supplies in the SPM. (Amended 15 April 2016)

Storage and handling of study vaccines 
The study vaccines must be stored at the respective label storage temperature conditions 
in a safe and locked place. Access to the storage space should be limited to authorised 
study personnel. The storage conditions will be assessed during pre-study activities under 
the responsibility of the sponsor study contact. The storage temperature should be 
continuously monitored with calibrated (if not validated) temperature monitoring 
device(s) and recorded. Refer to the Module on Clinical Trial Supplies in the SPM for 
more details on storage of the study vaccines. 
 
Temperature excursions must be reported in degree Celsius. 
 
Any temperature excursion outside the range of 0.0 to +8.0C (for +2 to +8°C label 
storage condition) impacting investigational medicinal products (IMPs) must be reported 
in the appropriate electronic Temperature Excursion Decision Form (eTDF). The 
impacted IMPs must not be used and must be stored in quarantine at label temperature 
conditions until usage approval has been obtained from the sponsor. 
 
In case of temperature excursion below +2.0°C down to 0.0°C impacting IMP(s) there is 
no need to report in eTDF, but adequate actions must be taken to restore the +2 to +8°C 
label storage temperature conditions. The impacted IMPs may still be administered, but 
the site should avoid re-occurrence of such temperature excursion. Refer to the Module 
on Clinical Trial Supplies in the SPM for more details on actions to take. 
 
Refer to the Module on Clinical Trial Supplies in the SPM for details and instructions on 
the temperature excursion reporting and usage decision process, packaging and 
accountability of the study vaccines.

Replacement of unusable vaccine doses 
In addition to the vaccine doses provided for the planned number of subjects (including 
over-randomisation when applicable), at least 20% additional vaccine doses will be 
supplied to replace those that are unusable. 
 
The investigator will use SBIR to obtain the replacement vial number. The replacement 
numbers will be allocated by dose. The system will ensure, in a blinded manner, that the 
replacement vial matches the formulation the subject was assigned to by randomisation. 
 
7.5. 
Contraindications to subsequent vaccination 
The following events constitute contraindications to administration of the investigational 
NTHi vaccine at that point in time; if any of these events occur at the time scheduled for 
vaccination, the subject may be vaccinated at a later date, within the time window 
specified in the protocol, or the subject may be withdrawn at the discretion of the 
investigator (see Section 9.5). 
• 
Moderate or severe AECOPD that is on-going or that has not been resolved for at 
least 7 days at the time of vaccination. 
• 
Acute disease and/ or fever at the time of vaccination. 
 
Fever is defined as oral or axillary temperature  37.5°C. The preferred route for 
recording temperature in this study will be oral. 
 
Subjects with a minor illness without fever can be administered all vaccines at 
the discretion of the investigator. 
 
The following events constitute absolute contraindications to further administration of the 
investigational NTHi vaccine. If any of these events occur during the study, the subject 
must not receive vaccine Dose 2. 
• 
Anaphylaxis following the administration of vaccine. 
• 
Pregnancy.

administered throughout the study period (including dose, unit, frequency and reason for 
use) must be recorded in the eCRF. 
 
7.6.2. 
Concomitant medications/products and vaccines that may lead 
to the elimination of a subject from ATP analysis for 
immunogenicity 
 
The use of the following concomitant medications/products/vaccines will not require 
withdrawal of the subject from the study but may determine a subject’s evaluability in the 
ATP analysis for immunogenicity. 
 
• 
Any investigational or non-registered product (drug or vaccine) other than the study 
vaccine used at any time during the entire study period. 
• 
A vaccine not foreseen by the study protocol administered during the period starting 
30 days before and ending 30 days after each dose of vaccine*, with the exception of 
any influenza or pneumococcal vaccines which may be administered  15 days 
preceding or following any dose of study vaccine. 
* In case an emergency mass vaccination for an unforeseen public health threat (e.g. 
a pandemic) is organised by the public health authorities, outside the routine 
immunisation program, the time period described above can be reduced if necessary

9.1. 
Safety definitions 
9.1.1. 
Definition of an adverse event 
 
An AE is any untoward medical occurrence in a clinical investigation subject, temporally 
associated with the use of a medicinal product, whether or not considered related to the 
medicinal product. 
 
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease (new or exacerbated) temporally associated with 
the use of a medicinal product. For marketed medicinal products, this also includes 
failure to produce expected benefits (i.e. lack of efficacy), abuse or misuse. 
 
Examples of an AE include: 
• 
Significant or unexpected worsening of the condition under study. 
• 
Exacerbation of a chronic or intermittent pre-existing condition, apart from the 
condition under study, including either an increase in frequency and/or intensity of 
the condition. 
• 
New conditions detected or diagnosed after investigational vaccine administration 
even though they may have been present prior to the start of the study. 
• 
Signs, symptoms, or the clinical sequelae of a suspected interaction. 
• 
Signs, symptoms temporally associated with vaccine administration. 
• 
Pre- or post-treatment events that occur as a result of protocol-mandated procedures 
(i.e. invasive procedures, modification of subject’s previous therapeutic regimen). 
 
AEs to be recorded as endpoints (solicited AEs) are described in Section 9.1.3. All other 
AEs will be recorded as UNSOLICITED AEs. 
 
Examples of an AE DO NOT include: 
• 
Medical or surgical procedures (e.g. endoscopy, appendectomy); the condition that 
leads to the procedure is an AE/ SAE. 
• 
Situations where an untoward medical occurrence did not occur (e.g. social and/or 
convenience admission to a hospital, admission for routine examination). 
• 
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. 
• 
The disease being studied, or expected progression, signs, or symptoms of the 
disease being studied, unless more severe than expected for the subject’s condition. 
• 
Pre-existing conditions or signs and/ or symptoms present in a subject prior to the 
first study vaccination. These events will be recorded in the medical history section 
of the eCRF.

9.1.2. 
Definition of a serious adverse event 
 
An SAE is any untoward medical occurrence that: 
a. 
Results in death, 
b. Is life-threatening, 
Note: 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, had it been more severe. 
c. 
Requires hospitalisation or prolongation of existing hospitalisation, 
Note: In general, hospitalisation signifies that the subject has been admitted at the 
hospital or emergency ward for observation and/ or treatment that would not have 
been appropriate in the physician’s office or in an out-patient setting. Complications 
that occur during hospitalisation are also considered AEs. If a complication prolongs 
hospitalisation or fulfils any other serious criteria, the event will also be considered 
serious. When in doubt as to whether ‘hospitalisation’ occurred or was necessary, the 
AE should be considered serious. 
Hospitalisation for elective treatment of a pre-existing condition (known or 
diagnosed prior to informed consent signature) that did not worsen from baseline is 
NOT considered an AE. 
d. Results in disability/ incapacity, OR 
Note: 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, diarrhoea, influenza like illness, and accidental trauma (e.g. sprained 
ankle) which may interfere or prevent everyday life functions but do not constitute a 
substantial disruption. 
e. 
Is a congenital anomaly/ birth defect in the offspring of a study subject. 
 
Medical or scientific judgement should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be 
immediately life-threatening or result in death or hospitalisation but may jeopardise the 
subject or may require medical or surgical intervention to prevent one of the other 
outcomes listed in the above definition. These should also be considered serious. 
Examples of such events are invasive or malignant cancers, intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or convulsions 
that do not result in hospitalisation. 
 
9.1.3. 
Solicited adverse events 
 
Solicited local and general AEs occurring during a 7-day follow-up period after each 
vaccination (i.e. the day of vaccination and the 6 subsequent days), as well as unsolicited 
AEs occurring during a 30-day follow-up period after each vaccination (i.e. the day of 
vaccination an the 29 subsequent days), will be reported via paper Diary Cards for 
vaccine reactogenicity and recorded via the appropriate section of the eCRF.

measurements be performed at other times of day, the highest temperature will be 
recorded in the eCRF. 
 
9.1.4. 
Clinical laboratory parameters and other abnormal assessments 
qualifying as adverse events or serious adverse events 
 
In absence of diagnosis, abnormal laboratory findings (e.g. clinical chemistry, 
haematology, urinalysis) or other abnormal assessments that are judged by the 
investigator to be clinically significant will be recorded as AE or SAE if they meet the 
definition of an AE or SAE (refer to Sections 9.1.1 and 9.1.2). Clinically significant 
abnormal laboratory findings or other abnormal assessments that are present at baseline 
and significantly worsen following the start of the study will also be reported as AEs or 
SAEs. However, clinically significant abnormal laboratory findings or other abnormal 
assessments that are associated with the disease being studied, unless judged by the 
investigator as more severe than expected for the subject’s condition, or that are present 
or detected at the start of the study and do not worsen, will not be reported as AEs or 
SAEs. 
 
The investigator will exercise his or her medical and scientific judgement in deciding 
whether an abnormal laboratory finding or other abnormal assessment is clinically 
significant. 
 
9.1.5. 
Adverse events of specific interest (potential immune-mediated 
diseases) 
 
pIMDs are a subset of AEs that include autoimmune diseases and other inflammatory 
and/or neurologic disorders of interest which may or may not have an autoimmune

aetiology. AEs that need to be recorded and reported as pIMDs include those listed in

9.2. 
Events or outcomes not qualifying as adverse events or 
serious adverse events 
9.2.1. 
AECOPD 
 
AECOPD are common in subjects with COPD. Because they are typically associated 
with the disease under study, only AECOPD meeting the definition of an SAE and 
occurring in the time period defined in Section 9.3.1 will be reported to GSK Biologicals 
as described in Sections 9.4.1 and 9.4.3. 
 
9.2.2. 
Pregnancy 
 
Female subjects who are pregnant or lactating at the time of vaccination must not receive 
additional doses of study vaccine but may continue other study procedures at the 
discretion of the investigator. 
 
While pregnancy itself is not considered an AE or SAE, any adverse pregnancy outcome 
or complication or elective termination of a pregnancy for medical reasons will be 
recorded and reported as an AE or a SAE. 
Note: the pregnancy itself should always be recorded on an electronic pregnancy report. 
 
The following should always be considered as SAE and will be reported as described in 
Sections 9.4.1 and 9.4.3: 
• 
Spontaneous pregnancy loss, including: 
 
Spontaneous abortion, (spontaneous pregnancy loss before/at 22 weeks of 
gestation). 
 
Ectopic and molar pregnancy. 
 
Stillbirth (intrauterine death of foetus after 22 weeks of gestation). 
Note: the 22 weeks cut-off in gestational age is based on WHO-ICD 10 noted in the 
EMA Guideline on pregnancy exposure [EMA, 2006]. It is recognised that national 
regulations might be different. 
• 
Any early neonatal death (i.e. death of a live born infant occurring within the first 7 
days of life). 
• 
Any congenital anomaly or birth defect (as per [EMA, 2006] guidelines) identified in 
the offspring of a study subject (either during pregnancy, at birth or later) regardless 
of whether the foetus is delivered dead or alive. This includes anomalies identified 
by prenatal ultrasound, amniocentesis or examination of the products of conception 
after elective or spontaneous abortion.

Furthermore, any SAE occurring as a result of a post-study pregnancy AND considered 
by the investigator to be reasonably related to the investigational vaccine/ product will be 
reported to GSK Biologicals as described in Section 9.4.3. While the investigator is not 
obligated to actively seek this information from former study participants, he/ she may 
learn of a pregnancy through spontaneous reporting. 
 
9.3. 
Detecting and recording adverse events, serious adverse 
events and pregnancies 
9.3.1. 
Time period for detecting and recording adverse events, serious 
adverse events and pregnancies 
 
All AEs starting within 29 days following administration of each dose of study vaccine 
must be recorded into appropriate section of the eCRF, irrespective of intensity or 
whether or not they are considered vaccination-related. 
 
All AEs/ SAEs leading to withdrawal from the study will be collected and recorded from 
the time of the first receipt of study vaccine until study conclusion. 
 
The time period for collecting and recording pIMDs will begin at the first receipt of study 
vaccine and will end at study conclusion. See section 9.4 for instructions on reporting of 
pIMDs. 
 
The time period for collecting and recording SAEs will begin at the first receipt of study 
vaccine and will end at study conclusion. See Section 9.4 for instructions on reporting of 
SAEs. 
 
In addition to the above-mentioned reporting requirements for SAEs and in order to fulfil 
international reporting obligations, SAEs that are related to study participation (i.e. 
protocol-mandated procedures, invasive tests, a change from existing therapy) or are 
related to a concurrent GSK medication/vaccine will be collected and recorded from the 
time the subject consents to participate in the study until she/ he is discharged from the 
study. See Section 9.4 for instructions on reporting of SAEs. 
 
The time period for collecting and recording pregnancies will begin at the first receipt of 
study vaccine and will end 6 months following administration of the last dose of study 
vaccine. See section 9.4 for instructions on reporting of pregnancies. 
 
The time period for collecting and recording intercurrent medical conditions that require 
medical attention will begin at the first receipt of study vaccine and will end at study 
conclusion. 
 
An overview of the protocol-required reporting periods for AEs, SAEs, and pregnancies 
is given in Table 21.

Post-Study adverse events and serious adverse events 
 
A post-study AE/ SAE is defined as any event that occurs outside of the AE/ SAE 
reporting period defined in Table 21. Investigators are not obligated to actively seek AEs 
or SAEs in former study participants. However, if the investigator learns of any SAE at 
any time after a subject has been discharged from the study, and he/ she considers the 
event reasonably related to the investigational vaccine/ product, the investigator will 
promptly notify the Study Contact for Reporting SAEs.

Evaluation of adverse events and serious adverse events 
 
9.3.3.1. 
Active questioning to detect adverse events and serious adverse 
events 
 
As a consistent method of collecting AEs, the subject should be asked a non-leading 
question such as: 
‘Have you felt different in any way since receiving the vaccine or since the previous 
visit?’ 
 
When an AE/ SAE occurs, it is the responsibility of the investigator to review all 
documentation (e.g. hospital progress notes, laboratory and diagnostics reports) relative 
to the event. The investigator will then record all relevant information regarding an AE/ 
SAE in the eCRF. The investigator is not allowed to send photocopies of the subject’s 
medical records to GSK Biologicals instead of appropriately completing the eCRF. 
However, there may be instances when copies of medical records for certain cases are 
requested by GSK Biologicals. In this instance, all subject identifiers will be blinded on 
the copies of the medical records prior to submission to GSK Biologicals. 
 
The investigator will attempt to establish a diagnosis pertaining to the event based on 
signs, symptoms, and/ or other clinical information. In such cases, the diagnosis should 
be documented as the AE/ SAE and not the individual signs/ symptoms.

The investigator will assess the maximum intensity that occurred over the duration of the 
event for all unsolicited AEs (including SAEs) recorded during the study. The assessment 
will be based on the investigator’s clinical judgement. 
 
The intensity should be assigned to one of the following categories: 
1 (mild) 
: 
An AE which is easily tolerated by the subject, causing 
minimal discomfort and not interfering with everyday 
activities. 
2 (moderate) 
: 
An AE which is sufficiently discomforting to interfere with 
normal everyday activities. 
3 (severe) 
: 
An AE which prevents normal, everyday activities. Such 
an AE would, for example, prevent attendance at 
work/school and would necessitate the administration of 
corrective therapy. 
 
An AE that is assessed as Grade 3 (severe) should not be confused with a SAE. Grade 3 
is a category used for rating the intensity of an event; and both AEs and SAEs can be 
assessed as Grade 3. An event is defined as ‘serious’ when it meets one of the pre-defined 
outcomes as described in Section 9.1.2 
 
9.3.3.2.2.       Assessment of causality 
 
The investigator is obligated to assess the relationship between investigational vaccine/ 
product and the occurrence of each AE/ SAE. The investigator will use clinical 
judgement to determine the relationship. Alternative plausible causes, such as natural 
history of the underlying diseases, concomitant therapy, other risk factors, and the 
temporal relationship of the event to the investigational vaccine/ product will be 
considered and investigated. The investigator will also consult the Investigator Brochure 
and its supplement to determine his/her assessment. 
 
There may be situations when a SAE has occurred and the investigator has minimal 
information to include in the initial report to GSK Biologicals. However, it is very 
important that the investigator always makes an assessment of causality for every event 
prior to submission of the SAE report to GSK Biologicals. The investigator may change 
his/ her opinion of causality in light of follow-up information and update the SAE 
information accordingly. The causality assessment is one of the criteria used when 
determining regulatory reporting requirements. 
 
In case of concomitant administration of multiple vaccines, it may not be possible to 
determine the causal relationship of general AEs to the individual vaccines administered. 
The investigator should, therefore, assess whether the AE could be causally related to 
vaccination rather than to the individual vaccines.

All solicited local (injection site) reactions will be considered causally related to 
vaccination. Causality of all other AEs should be assessed by the investigator using the 
following question: 
Is there a reasonable possibility that the AE may have been caused by the investigational 
vaccine? 
 
YES 
: 
There is a reasonable possibility that the vaccine contributed to 
the AE. 
NO 
: 
There is no reasonable possibility that the AE is causally 
related to the administration of the study vaccine. There are 
other, more likely causes and administration of the study 
vaccine is not suspected to have contributed to the AE. 
 
If an event meets the criteria to be determined as ‘serious’ (see Section 9.1.2), additional 
examinations/ tests will be performed by the investigator in order to determine ALL 
possible contributing factors for each SAE. 
 
Possible contributing factors include: 
• 
Medical history. 
• 
Other medication. 
• 
Protocol required procedure. 
• 
Other procedure not required by the protocol. 
• 
Lack of efficacy of the vaccine, if applicable. 
• 
Erroneous administration. 
• 
Other cause (specify). 
 
9.3.3.3. 
Assessment of outcomes 
 
The investigator will assess the outcome of all unsolicited AEs (including SAEs) 
recorded during the study as: 
• 
Recovered/ resolved. 
• 
Recovering/ resolving. 
• 
Not recovered/ not resolved. 
• 
Recovered with sequelae/ resolved with sequelae. 
•

Once onset of a new pIMD or exacerbation of a pre-existing pIMD is diagnosed (serious 
or non-serious) in a study subject, the investigator (or designate) must complete the 
information in the electronic SAE report WITHIN 24 HOURS after he/she becomes 
aware of the diagnosis. A field on the SAE report allows specifying that the event is a 
pIMD and whether it is serious or non-serious. The SAE report will always be completed 
as thoroughly as possible with all available details of the event, in accordance with the 
pIMD standard questionnaire provided. Even if the investigator does not have all 
information regarding a pIMD, the report should still be completed within 24 hours. Once 
additional relevant information is received, the report should be updated WITHIN 24 
HOURS. 
 
The investigator will always provide an assessment of causality at the time of the initial 
report. 
 
Refer to Section 9.4.3.1 for back-up system in case the electronic SAE reporting system

Completion and transmission of SAE reports to GSK Biologicals 
 
Once an investigator becomes aware that a SAE has occurred in a study subject, the 
investigator (or designate) must complete the information in the electronic SAE report 
WITHIN 24 HOURS. The SAE report will always be completed as thoroughly as 
possible with all available details of the event. Even if the investigator does not have all 
information regarding a SAE, the report should still be completed within 24 hours. Once 
additional relevant information is received, the report should be updated WITHIN 24 
HOURS. 
 
The investigator will always provide an assessment of causality at the time of the initial 
report. 
 
Refer to Section 9.4.3.1 for back-up system in case the electronic SAE reporting system 
does not work. 
 
9.4.3.1. 
Back-up system in case the electronic SAE reporting system does not 
work 
 
If the electronic SAE reporting system does not work, the investigator (or designate) must 
complete, then date and sign a paper SAE report and fax it to the GSK Biologicals 
Clinical Safety and Pharmacovigilance department within 24 hours. 
 
This back-up system should only be used if the electronic SAE reporting system is not 
working and NOT if the system is slow. As soon as the electronic SAE reporting system 
is working again, the investigator (or designate) must complete the electronic SAE report 
within 24 hours. The final valid information for regulatory reporting will be the 
information reported through the electronic SAE reporting system. 
 
 
 
9.4.4. 
Completion and transmission of pregnancy reports to GSK 
Biologicals 
 
Once the investigator becomes aware that a subject is pregnant, the investigator (or 
designate) must complete the required information onto the electronic pregnancy report 
WITHIN 2 WEEKS. 
 
Note: Conventionally, the estimated gestational age (EGA) of a pregnancy is dated from 
the first day of the last menstrual period (LMP) of the cycle in which a woman conceives. 
If the LMP is uncertain or unknown, dating of EGA and the estimated date of delivery 
(EDD) should be estimated by ultrasound examination and recorded in the pregnancy 
report.

Updating of pIMD, SAE and pregnancy information after freezing 
of the subject’s eCRF 
 
When additional pIMD, SAE or pregnancy information is received after freezing of the 
subject’s eCRF, new or updated information should be recorded on a paper report, with 
all changes signed and dated by the investigator. The updated report should be faxed to 
the GSK Biologicals Clinical Safety and Pharmacovigilance department or to the Back- 
up Study Contact for Reporting SAEs (see Section 9.4.3.1) within the designated 
reporting time frames specified in Table 23. 
 
9.4.6. 
Regulatory reporting requirements for serious adverse events 
 
The investigator will promptly report all SAEs to GSK in accordance with the procedures 
detailed in Section 9.4.1. GSK Biologicals has a legal responsibility to promptly notify, 
as appropriate, both the local regulatory authority and other regulatory agencies about the 
safety of a product under clinical investigation. Prompt notification of SAEs by the 
investigator to the Study Contact for Reporting SAEs is essential so that legal obligations 
and ethical responsibilities towards the safety of other subjects are met. 
 
Investigator safety reports are prepared according to the current GSK policy and are 
forwarded to investigators as necessary. An investigator safety report is prepared for a 
SAE(s) that is both attributable to the investigational vaccine/ product and unexpected. 
The purpose of the report is to fulfil specific regulatory and GCP requirements, regarding 
the product under investigation.

9.5.1.1. 
Follow-up during the study 
 
After the initial AE/ SAE report, the investigator is required to proactively follow each 
subject and provide additional relevant information on the subject’s condition to GSK 
Biologicals (within 24 hours for SAEs; refer to Table 23). 
 
All AEs documented at a previous visit/ contact and designated as not recovered/ not 
resolved or recovering/ resolving will be reviewed at subsequent visits/ contacts until 30 
days after the last vaccination. 
 
All pIMDs (serious or non-serious) and SAEs documented at a previous visit/ contact and 
designated as not recovered/not resolved or recovering/ resolving will be reviewed at 
subsequent visits/contacts. 
 
9.5.1.2. 
Follow-up after the subject is discharged from the study 
 
The investigator will follow subjects with pIMDs (serious or non-serious), SAEs or 
subjects withdrawn from the study as a result of an AE until the event has resolved,

subsided, stabilised, disappeared, or until the event is otherwise explained, or the subject 
is lost to follow-up. 
 
If the investigator receives additional relevant information on a previously reported SAE, 
he/ she will provide this information to GSK Biologicals using a paper SAE and/ or 
pregnancy report as applicable. 
 
GSK Biologicals may request that the investigator performs or arranges the conduct of 
additional clinical examinations/ tests and/ or evaluations to elucidate as fully as possible 
the nature and/ or causality of the AE or SAE. The investigator is obliged to assist. If a 
subject dies during participation in the study or during a recognised follow-up period, 
GSK Biologicals will be provided with any available post-mortem findings, including 
histopathology. 
 
9.5.2. 
Follow-up of pregnancies 
 
Pregnant subjects will be followed to determine the outcome of the pregnancy. At the end 
of the pregnancy, whether full-term or premature, information on the status of the mother 
and child will be forwarded to GSK Biologicals using the electronic pregnancy report and 
the SAE report, if applicable. Generally, the follow-up period does not need to be longer 
than six to eight weeks after the estimated date of delivery. 
 
Regardless of the reporting period for SAEs for this study, if the pregnancy outcome is a 
SAE, it should always be reported as SAE. 
 
9.6. 
Treatment of adverse events 
Treatment of any AE is at the sole discretion of the investigator and according to current 
good medical practice. Any medication administered for the treatment of an AE should 
be recorded in the subject’s eCRF (refer to Section 7.6). 
 
9.7. 
Unblinding 
GSK Biologicals’ policy (which incorporates ICH E2A guidance, EU Clinical Trial 
Directive and USA Federal Regulations) is to unblind the report of any SAE which is 
unexpected and attributable/suspected to be attributable to the investigational vaccine/ 
product, prior to regulatory reporting. The GSK Biologicals’ Central Safety Physician is 
responsible for unblinding the treatment assignment in accordance with the specified 
timeframes for expedited reporting of SAEs (refer to Section 9.4.1). 
 
9.8. 
Emergency unblinding 
Unblinding of a subject’s individual treatment code should occur only in the case of a 
medical emergency, or in the event of a serious medical condition, when knowledge of 
the study treatment is essential for the clinical management or welfare of the subject, as 
judged by the investigator.

The emergency unblinding process consists of the automated internet-based system SBIR 
that allows the investigator to have unrestricted, immediate and direct access to the 
subject’s individual study treatment. 
 
The investigator has the option of contacting a GSK Biologicals’ On-Call Central Safety 
Physician (or back-up) if he/ she needs medical advice or needs the support of GSK to 
perform the unblinding (i.e. he/ she cannot access the automated internet-based system 
SBIR). 
 
Any emergency unblinding must be fully documented using the Emergency Unblinding 
Documentation Form, which must be appropriately completed by the investigator and 
sent to GSK Biologicals within 24 hours. 
 
 
9.9. 
Subject card 
Study subjects must be provided with the address and telephone number of the main 
contact for information about the clinical study. 
 
The investigator (or designate) must therefore provide a “subject card” to each subject. In 
an emergency situation this card serves to inform the responsible attending physician that 
the subject is in a clinical study and that relevant information may be obtained by 
contacting the investigator. 
 
Subjects must be instructed to keep subject cards in their possession at all times.

Safety Review Team 
 
The project’s SRT includes as core members the GSK Biologicals’ Central Safety 
Physician, the Clinical Research & Development Lead (CRDL), Epidemiologist, Clinical 
Regulatory Affairs representative and the Biostatistician of the project. The SRT is 
responsible for on-going safety monitoring of the entire project and meets on a regular 
basis. The SRT will inform the iSRC about any potential safety concern relevant to the 
study.

Before each iSRC safety evaluation in this study (see below), the SRT will review the 
same safety data, but in a blinded manner in order to keep all people involved in the 
conduct, cleaning and final analysis of the study blinded. 
 
9.10.2. 
Internal Safety Review Committee 
 
As the investigational vaccine will be administered for the first time to moderate and 
severe COPD patients, an iSRC will be appointed next to the existing project’s SRT and 
safety holding rules have been defined (see Table 24). 
 
The iSRC will be authorised by GSK Biologicals’ VSMB and its core members will 
include a GSK Biologicals’ Safety Physician, a CRDL and a Biostatistician who are not 
otherwise involved in the conduct of the project. If none of the core members listed above 
is a respiratory expert, such an expert will be included. 
 
The iSRC will conduct unblinded reviews of all available safety data from the present 
study, including data on AECOPD (frequency, intensity and duration), while taking into 
account any other findings that could have an impact on the safety of the subjects, and 
will determine whether there is a safety signal that needs to be escalated to GSK 
Biologicals’ VSMB. In the event that a safety signal is observed, GSK Biologicals’ 
VSMB might decide to suspend, modify or continue the conduct of the study. 
 
Administration of vaccine Dose 1 will follow a staggered design, starting with 
vaccination of GOLD 2 subjects only. Administration of vaccine Dose 1 to GOLD 3 
subjects will depend on the favourable outcome of an iSRC evaluation of safety data up 
to at least day 6 after vaccination from about 20 GOLD 2 subjects (i.e. approximately 10 
subjects/ group). 
 
In addition, starting administration of vaccine Dose 2 will for each GOLD grade depend 
on the favourable outcome of an iSRC evaluation of all available safety data. 
 
In addition to the planned iSRC evaluations, ad hoc safety evaluations can take place if a 
safety concern is identified by an investigator (e.g. meeting of holding rules 1a-c) or by 
the SRT.

Study holding rules 
 
As the investigational NTHi vaccine will be administered for the first time to moderate 
and severe COPD patients, study holding rules have been defined (see Table 24). 
 
• 
Holding rules 1a, 1b and 1c will be monitored by the investigators on a continuous 
basis for as long as vaccination is on-going in the study. Meeting any of these 
holding rules will trigger a hold of vaccination irrespective of the number of subjects 
vaccinated. 
• 
Holding rules 2a, 2b and 2c will be assessed by the iSRC during the safety 
evaluations.

SUBJECT COMPLETION AND WITHDRAWAL 
10.1. 
Subject completion 
A subject who returns for the concluding visit foreseen in the protocol is considered to 
have completed the study. 
 
10.2. 
Subject withdrawal 
Withdrawals will not be replaced. 
 
10.2.1. 
Subject withdrawal from the study 
 
From an analysis perspective, a ‘withdrawal’ from the study refers to any subject who did 
not come back for the concluding visit foreseen in the protocol. A subject is considered a 
‘withdrawal’ from the study when no study procedure has occurred, no follow-up has 
been performed and no further information has been collected for this subject from the 
date of withdrawal/ last contact. 
 
Investigators will make an attempt to contact those subjects who do not return for 
scheduled visits or follow-up. 
 
All data collected until the date of withdrawal/ last contact with the subject will be used 
for the analysis. If the subject agrees, the investigator should make an attempt to collect 
safety information until the initially planned date for study conclusion, either by phone, 
or by inviting the subject to a site visit around Day 450. 
 
Information relative to the withdrawal will be documented in the eCRF. The investigator 
will document whether the decision to withdraw a subject from the study was made by 
the subject himself/ herself or by the investigator, as well as which of the following 
possible reasons was responsible for withdrawal: 
• 
SAE. 
• 
Non-serious AE. 
• 
Protocol violation (specify). 
• 
Consent withdrawal, not due to an AE*. 
• 
Moved from the study area. 
• 
Lost to follow-up. 
• 
Other (specify). 
*In case a subject is withdrawn from the study because he/ she has withdrawn consent, 
the investigator will document the reason for withdrawal of consent, if specified by the 
subject, in the eCRF. 
 
Subjects who are withdrawn from the study because of (S)AEs must be clearly 
distinguished from subjects who are withdrawn for other reasons. Investigators will

follow subjects who are withdrawn from the study as result of a (S)AE until resolution of 
the event (see Section 9.5.1.2). 
 
10.2.2. 
Subject withdrawal from investigational vaccine 
 
A ‘withdrawal’ from the investigational vaccine refers to any subject who does not 
receive the complete treatment, i.e. when no further planned dose is administered from 
the date of withdrawal. A subject withdrawn from the investigational vaccine may not 
necessarily be withdrawn from the study as further study procedures or follow-up may be 
performed (safety or immunogenicity) if planned in the study protocol (see also Section 
7.5). 
 
Information relative to premature discontinuation of the investigational vaccine will be 
documented on the Vaccine Administration screen of the eCRF. The investigator will 
document whether the decision to discontinue further vaccination was made by the 
subject himself/ herself or by the investigator, as well as which of the following possible 
reasons was responsible for withdrawal: 
• 
SAE. 
• 
Non-serious AE. 
• 
Other (specify). 
10.3. 
Screening failures 
Screening failures are defined as subjects who are withdrawn from the study after giving 
informed consent, but who do not meet the inclusion and exclusion criteria. 
 
The following information will be collected for screening failures: 
• 
Informed consent. 
• 
Demographic data. 
• 
Inclusion/exclusion criteria. 
• 
SAEs related to study participation that occurred after signing informed consent. 
• 
Screening conclusion.

Determination of sample size 
This study is a Phase II safety study to assess safety and reactogenicity of the 
investigational vaccine in moderate and severe COPD patients. 
 
Considering the sample size of 70 in the group 10-AS01E, Figure 4 illustrates the 
probability of detecting an AE with true occurrence rate 0 - 10%. 
 
Figure 4 
Probability not to observe an AE for 60, 70 or 80 subjects per group 
 
From Figure 4, it can be seen that with a sample size of 70 subjects per group, there is 
more than 50% of chance to detect an AE with a true incidence of 1%, and more than 
97% of chance to detect an AE with a true incidence of 5%.

11.6. 
Derived and transformed data 
The study groups will be defined by treatment actually administered at Dose 1. 
 
Demography 
• 
For a given subject and a given demographic variable, missing measurement will not 
be replaced. 
 
Safety 
• 
For solicited symptoms, the analysis will exclude subjects with missing or 
un-evaluable measurements (i.e. total analysis of solicited symptoms will include all 
vaccinated subjects with documented solicited symptom sheets). 
• 
For the unsolicited symptoms and concomitant medications/ products/ vaccinations,

vaccinations will be treated as subjects without unsolicited symptoms or concomitant 
medications/ products/ vaccinations, respectively. 
 
Immunogenicity 
• 
For a given subject and the analysis of a given immunogenicity measurement, 
missing or un-evaluable measurements will not be replaced. 
• 
A seronegative subject is defined as a subject whose antibody concentration is below 
the assay cut-off value. 
• 
A seropositive subject is defined as a subject whose antibody concentration is greater 
than or equal to the assay cut-off value. 
•

• 
Calculation of the GMCs will be performed by taking the anti-logarithm in base 10 
(anti-log10) of the mean of the log10 concentration transformations. 
 
Impact of the investigational vaccine on AECOPD 
• 
For a given subject and the analysis of a given laboratory assay, missing or 
un-evaluable measurements will not be replaced. 
• 
Subjects who did not have any sputum collected during at least 1 AECOPD (if at 
least 1 AECOPD occurred) will not be taken into account for the NTHI-associated 
AECOPD analyses. 
• 
For summaries of the number of AECOPD occurring during the 1 year follow-up 
period starting 1 month post-Dose 2, an exacerbation rate will be calculated for each 
subject. The number of exacerbations during the 1-year follow-up period will be 
imputed for subjects withdrawing from the study to provide an estimate of the 
number of exacerbations over the follow-up period. This calculation will only be 
performed for purposes of reporting summary statistics for the rate of exacerbations 
during the 1 year follow-up period since the modelling of exacerbations takes into 
account the number of exacerbations and the time of follow-up for each subject. The 
calculation of exacerbation rate will be based on follow-up period intervals to avoid 
obtaining high imputed rates if a subject withdrew very early in the follow-up period 
after experiencing an exacerbation. Since treatment courses for moderate/severe 
exacerbations are  2 - 4 weeks when appropriate, calculated numbers of 
exacerbations for subjects withdrawing from the study will be based on 4-week 
intervals of the follow-up period. For subjects followed for less than 1 year, the 
number of exacerbations during the 1-year follow-up period will be calculated by 
multiplying the number of exacerbations experienced by the subject by 13 and 
dividing by the number of 4-week periods the subject was followed up [Stockley, 
2006]: 
Number of exacerbations per year = Number of exacerbations * 13 /Number of 
4-week treatment period intervals 
 
HRQOL 
• 
The CAT index will be derived as the sum of the ratings recorded for each of the 
eight individual items. Each of these items has 6 possible scores (0, 1, 2, 3, 4 or 5), 
leading to a range of 0 to 40 for CAT score. 
 
11.7. 
Analysis of demographics 
Demographic characteristics (age at the first dose in years, gender and geographical 
ancestry) and cohort description will be summarized by group using descriptive statistics: 
• 
Frequency tables will be generated for categorical variable such as geographical 
ancestry; 
• 
Mean, median and standard error will be provided for continuous data such as age. 
The distribution of subjects enrolled among the study sites will be tabulated as a whole 
and per group.

The number of subjects enrolled into the study as well as the number of subjects 
excluded from ATP analyses will be tabulated. 
 
11.8. 
Analysis of safety 
The analysis will be performed on the TVC. If the percentage of vaccinated subjects 
excluded from the ATP cohort for efficacy is at least 10%, a second analysis will be 
performed on the ATP cohort for efficacy to complement the first analysis. 
 
The percentage of subjects with at least one local AE (solicited and unsolicited), with at 
least one general AE (solicited and unsolicited) and with any AE during the 7-day (day 0 
– day 6) or the 30-day (day 0 – day 29) follow-up period will be tabulated after each 
vaccination and overall with exact 95% confidence interval (CI). The same computations 
will be done for Grade 3 AEs, for related AEs and for Grade 3 related AEs. 
 
The percentage of subjects/doses reporting each individual solicited local (any grade, 
Grade 3) and general (any grade, Grade 3, related, Grade 3 related) AE during the 7-day 
(day 0 to day 6) follow-up period will be tabulated for each group as follows: 
• 
Overall, the percentage of subjects with the symptom and its exact 95% CI. 
• 
Overall, the percentage of doses with the symptom and its exact 95% CI. 
• 
Per study vaccine dose, the percentage of subjects with the symptom and its exact 
95% CI. 
 
The exact 95% CIs will be calculated assuming independence between doses. For fever, 
additional analyses will be performed by 0.5°C increments. 
 
The verbatim reports of unsolicited symptoms will be reviewed by a physician and the 
signs and symptoms will be coded according to the MedDRA Dictionary for Adverse 
Reaction Terminology. Every verbatim term will be matched with the appropriate 
preferred term (PT). The percentage of subjects with unsolicited symptoms during the 
30-day follow-up period after any study vaccine dose with its exact 95% CI will be 
tabulated by group and by MedDRA PT. Similar tabulation will be done for the 
percentage of doses, for Grade 3 unsolicited symptoms, for unsolicited symptoms that 
resulted in a medically attended visit, for Grade 3 and causally related unsolicited 
symptoms and for unsolicited symptoms causally related to vaccination. 
 
For each group and for each haematology/ biochemistry parameter: 
• 
The percentage of subjects having results below or above the local laboratory normal 
ranges will be tabulated by time point. 
• 
The maximum grading from Screening up to study conclusion will be tabulated. 
Grades will be based on the FDA Guidance for Industry “Toxicity Grading Scale for

Healthy Adults and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical 
Trials” (see APPENDIX C). 
The number of subjects who experienced any pIMD or any SAE from first vaccination 
up to 6 months post-Dose 2 will be reported. 
 
The number of subjects who experienced any AE leading to study withdrawal, from 
first vaccination up to study conclusion, or any SAE related to study participation of 
concurrent GSK medication/ vaccination, during the entire study period, will be 
reported. 
 
Pregnancy exposures from first vaccination up to 6 months after last vaccination and 
pregnancy outcomes will be described in detail. 
 
The percentage of subjects/ dose using concomitant medication/ product (any 
medication/ product, any antipyretic and any antipyretic taken prophylactically, 
respectively) during the 7-day follow-up period (day 0 – day 6) and during the 30-day 
follow-up period (day 0 – day 29) will be summarised per group for each dose and 
overall per dose. 
 
11.8.1. 
iSRC safety evaluations 
 
Unblinded review of safety data will be done during iSRC evaluations (refer to Section 
9.10 for more information). No individual clinical study report will be written as a result 
of these safety evaluations. 
 
11.9. 
Analysis of immunogenicity 
The analysis will be performed on the ATP cohort for immunogenicity. If the percentage 
of vaccinated subjects with serological results excluded from the ATP cohort for analysis 
of immunogenicity is more than 10%, a second analysis will be performed on the TVC. 
 
Humoral immune response 
Within group evaluation 
For each group, at each time point during which blood samples are collected for humoral 
immune response and for each assay: 
• 
Seropositivity rate and their exact 95% CI will be tabulated. 
• 
GMCs and their 95% CI will be calculated. 
For each group, at each time point during which blood samples are collected for humoral 
immune response: 
• 
Antibody concentrations distribution will be investigated using Reverse Cumulative 
Curves.

Between groups evaluation 
Comparative analyses will be exploratory with the aim to characterise the difference 
between the 2 groups in humoral immune response. 
 
The difference in terms of GMCs will be evaluated at 1 month post-Dose 2 by computing 
the 95% CIs of the GMC ratio between groups by using an ANCOVA model that 
considers heterogeneity of variances (via Proc Mixed) on the logarithm10 
transformation of the concentrations. This model will include country, the group, age 
category (40 - 59 years or 60 - 80 years), number of moderate and severe AECOPD in the 
year before vaccine Dose 1 (< 2 or  2), GOLD grade (GOLD 2 or GOLD 3) and pre- 
Dose 1 concentration (as covariate) as fixed effects. (Amended 15 April 2016) 
 
However, these differences should be interpreted with caution considering that there will 
be no adjustment for multiplicity of endpoints. 
 
Cell-mediated immune response 
The frequency of specific CD4+/ CD8+ T-cells will be summarised by group, at each time 
point during which blood samples are collected for CMI (descriptive statistics). 
 
11.10. 
Analysis of impact of the investigational vaccine on 
AECOPD 
The analysis will be performed on the ATP cohort for efficacy. If the percentage of 
vaccinated subjects excluded from the ATP cohort for efficacy is more than 10%, a 
second analysis based on the TVC will be performed to complement the first analysis. 
 
The following incidence rates will be computed over a period starting 1 month 
post-Dose 2 and lasting for 1 year, with 95%CI: 
• 
NTHi-associated moderate and severe AECOPD. 
• 
NTHi-associated all-severity AECOPD. 
• 
All-cause moderate and severe AECOPD. 
• 
All-cause, all-severity AECOPD. 
The 95% CI of the incidence rate will be computed using a model which accounts for 
repeated events. The Generalised linear model assuming the Negative Binomial 
distribution for the response variable with logarithm as link function, and the logarithm of 
time for follow-up as an offset variable will be used. If the model does not converge, the 
Poisson distribution will be used instead of the Negative Binomial one.

Vaccine efficacy (VE) for AECOPD events will be defined as: 
VE (AECOPD) = 1 - Rvaccine / Rcontrol 
 
with: 
• 
Rvaccine = average yearly incidence rate of AECOPD events per subject in the 
group 10-AS01E. 
• 
Rcontrol = average yearly incidence rate of AECOPD events per subject in the 
Control group. 
In case the 95% CI of the VE cannot be estimated, e.g. when no event is observed in the 
group 10-AS01E (leading to a VE of 100%), then an exact procedure will be used to 
estimate a VE and its 95% CI. This exact procedure will be based on the number of 
subjects with event instead of on the average number of event per subject in each group. 
 
VE in the prevention of NTHi-associated moderate and severe AECOPD and its 95% CI 
will be calculated. 
 
VE in the prevention of NTHi-associated all-severity AECOPD, of all-cause moderate 
and severe AECOPD and of all-cause, all-severity AECOPD and their 95% CI will also 
be calculated. 
 
The time until first AECOPD as of 1 month post-Dose 2 will be computed with exact 
95% CI by group. Subjects who exacerbate before 1 month post-Dose 2 will not be taken 
into account in this analysis. 
 
The proportion of sputum samples with exact 95% CI obtained at each visit (scheduled 
visits and AECOPD-driven visits) and positive for bacterial pathogens (overall and by 
bacterial pathogen) will be computed by group and overall. The exact 95% CI will be 
estimated assuming independence of bacterial results across sputum samples. 
 
11.11. 
Analysis of HRQOL, lung capacity and exercise capacity 
The analysis will be performed on the TVC. If the percentage of vaccinated subjects 
excluded from the ATP cohort for efficacy is at least 10%, a second analysis will be 
performed on the ATP cohort for efficacy to complement the first analysis. 
 
Descriptive statistics (median, mean, range, standard deviation, first and third quartiles) 
on the EXACT-PRO, CAT, SGRQ-C and mMRC scores, on FEV1% of predicted 
normal value and on the 6MWT scores will be tabulated by specified visit. 
 
Descriptive summaries rescue medication and healthcare use for AECOPD will be 
provided. 
 
11.12. 
Analysis of selected biomarkers 
The analysis will be performed on the ATP cohort for efficacy. If the percentage of 
vaccinated subjects excluded from the ATP cohort for efficacy is at least 10%, a second 
analysis will be performed on the TVC to complement the first analysis.

Interpretation of analyses 
Comparative analyses with the aim to characterise the difference in reactogenicity/ 
immunogenicity/ efficacy between groups will be descriptive. These descriptive analyses 
should be interpreted with caution. 
 
11.14. 
Conduct of analyses 
Any deviation(s) or change(s) from the original statistical plan outlined in this 
protocol will be described and justified in the final study report. 
 
11.14.1. 
Sequence of analyses (Amended 15 April 2016) 
 
The analyses will be performed stepwise: 
• 
The analysis of data up to Visit 6 (Day 90) will be performed in a first step. This 
analysis will include: 
 
The final analysis of immunogenicity and solicited AEs post-Dose 1 and post- 
Dose 2. 
 
The assessment of unsolicited AEs, SAEs and pIMDs up to 30 days post-Dose 1 
and post-Dose 2 on as cleaned as possible data. 
This analysis will be documented in a statistical report. At this point, the GSK 
statistician of the project (or delegates) will be unblinded (i.e. will have access to the 
individual subject treatment assignments). 
• 
The analyses of the impact of the investigational vaccine on AECOPD will be 
performed in parallel with the first step. This will include: 
 
the analyses of fresh sputum samples (culture) obtained up to the data lock 
point of the interim analysis. 
 
The analyses of AECOPD obtained up to the data lock point of the interim 
analysis. 
• 
The final analysis of data up to study conclusion will be performed in a second step, 
once those data will be available and cleaned. This analysis will include: 
 
The final analysis of immunogenicity at Day 270 and Day 450. 
 
SAEs and pIMDs up to Day 450 on cleaned data. 
 
Impact of the investigational vaccine on AECOPD, HRQOL, lung function, 
exercise capacity and biomarkers. 
In addition, all previous analyses will be re-produced based on cleaned data at this 
point.

Individual listings will only be provided at this stage. An integrated study report 
containing data from the entire study will be written at the end of the study and will 
be made available to the investigators. 
 
11.14.2. 
Statistical considerations for interim analyses 
 
All analyses are descriptive, and performed on final or as clean as possible data therefore 
no adjustment needs to be performed. 
 
12. 
ADMINISTRATIVE MATTERS 
To comply with ICH GCP administrative obligations relating to data collection, 
monitoring, archiving data, audits, confidentiality and publications must be fulfilled. 
 
12.1. 
Case Report Form/Remote Data Entry instructions 
Remote Data Entry (RDE), a validated computer application, will be used as the method 
for data collection. 
 
In all cases, subject initials will not be collected nor transmitted to GSK. Subject data 
necessary for analysis and reporting will be entered/transmitted into a validated database 
or data system. Clinical data management will be performed in accordance with 
applicable GSK standards and data cleaning procedures. 
 
While completed eCRFs are reviewed by a GSK Biologicals’ Site Monitor at the study 
site, omissions or inconsistencies detected by subsequent eCRF review may necessitate 
clarification or correction of omissions or inconsistencies with documentation and 
approval by the investigator or appropriately qualified designee. In all cases, the 
investigator remains accountable for the study data. 
 
The investigator will be provided with a CD-ROM of the final version of the data 
generated at the investigational site once the database is archived and the study report is 
complete and approved by all parties. 
 
12.2. 
Study Monitoring by GSK Biologicals 
GSK will monitor the study to verify that, amongst others, 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, any other 
study agreements, GCP and all applicable regulatory requirements. 
The investigator and the head of the medical institution (where applicable) agrees to 
allow the monitor direct access to all relevant documents. 
 
The investigator must ensure provision of reasonable time, space and qualified personnel 
for monitoring visits.

Direct access to all study-site related and source data is mandatory for the purpose of 
monitoring review. The monitor will perform an RDE review and a Source Document 
Verification (SDV). By SDV we understand verifying RDE entries by comparing them 
with the source data that will be made available by the investigator for this purpose. 
 
The Source Documentation Agreement Form describes the source data for the different 
data in. This document should be completed and signed by the site monitor and 
investigator and should be filed in the monitor’s and investigator’s study file. Any data 
item for which RDE will serve as the source must be identified, agreed and documented 
in the source documentation agreement form. 
 
For RDE, the monitor will freeze completed and approved screens at each visit. 
 
Upon completion or premature discontinuation of the study, the monitor will conduct site 
closure activities with the investigator or site staff, as appropriate, in accordance with 
applicable regulations, GCP, and GSK procedures. 
 
12.3. 
Record 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. The records must be easily accessible, when needed (e.g. audit or 
inspection), and must be available for review in conjunction with assessment of the 
facility, supporting systems, and staff. Where permitted by applicable laws/regulations or 
institutional policy, some or all of these records can be maintained in a validated 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 that an acceptable back-up of the reproductions exists and that 
there is an acceptable quality control procedure in place for making these reproductions. 
 
GSK will inform the investigator/institution of the time period for retaining these records 
to comply with all applicable regulatory requirements. However, the 
investigator/institution should seek the written approval of the sponsor before proceeding 
with the disposal of these records. The minimum retention time will meet the strictest 
standard applicable to a particular site, as dictated by ICH GCP, any institutional 
requirements, applicable laws or regulations, or GSK standards/procedures; otherwise, 
the minimum retention period will default to 15 years. 
 
The investigator/ institution must notify GSK of any changes in the archival 
arrangements, including, but not limited to archival at an off-site facility, transfer of 
ownership of the records in the event the investigator leaves the site. 
 
12.4. 
Quality assurance 
To ensure compliance with GCP and all applicable regulatory requirements, GSK may 
conduct a quality assurance audit. Regulatory agencies may also conduct a regulatory 
inspection of this study. Such audits/inspections can occur at any time during or after

completion of the study. If an audit or inspection occurs, the investigator and institution 
agree to allow the auditor/inspector direct access to all relevant documents and to allocate 
his/her time and the time of his/her staff to the auditor/inspector to discuss findings and 
any relevant issues. 
 
12.5. 
Posting of information on publicly available clinical trial 
registers and publication policy 
Study information from this protocol will be posted on publicly available clinical trial 
registers before enrolment of subjects begins. 
 
Summaries of the results of GSK interventional studies (Phase I-IV) are posted on 
publicly available results registers within 12 months of the primary completion date for 
studies of authorised vaccines and 18 months for studies of non-authorised vaccines. 
 
GSK also aims to publish the results of these studies in the searchable, peer reviewed 
scientific literature. Manuscripts are submitted for publication within 24 months of the 
last subject’s last visit. 
 
12.6. 
Provision of study results to investigators 
Where required by applicable regulatory requirements, an investigator signatory will be 
identified for the approval of the 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 Biologicals 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.

LABORATORY ASSAYS 
Humoral antibody responses (Amended 15 April 2016) 
Anti-PD antibodies 
Anti-PD antibodies will be determined using an ELISA assay developed by GSK 
Biologicals. Concentration of specific anti-PD antibodies will be determined, using 
in-house made reference serum. The current cut-off of the assay is 153 EL.U/mL. 
 
Anti-PE antibodies 
Anti-PE antibodies will be determined using an ELISA assay developed by GSK 
Biologicals. Concentration of specific anti-PE antibodies will be determined, using in- 
house made reference serum. The cut-off of the assay is 8 EL.U/mL. 
 
Anti-PilA antibodies 
Anti-PilA antibodies will be determined using an ELISA assay developed by GSK 
Biologicals. Concentration of specific anti-PilA antibodies will be determined, using an 
in-house made reference serum. The cut-off of the assay is 7 EL.U/mL. 
 
Cell-mediated immunity 
The ICS staining assay will be used to assess CMI responses, using an adaptation of 
previously described methods [Moris, 2011]. After PBMC stimulation with the relevant 
antigens, the frequency of CD4+ and/or CD8+ T-cells expressing selected set of cytokines 
(such as IL-2, IL-13, IL-17, IFN-γ, TNF-α and CD40L) or selected combination of 
cytokines will be evaluated by flow cytometry. 
 
Microbiological assessments 
Bacterial pathogen identification and bacterial load 
Evidence and identification of S. pneumoniae, H. influenzae, M. catarrhalis and other 
bacterial pathogens (including S. aureus, P. aeruginosa and S. pyogenes) in sputum 
specimens will be investigated using standard microbiological culture and standard 
bacteriological procedures [Murray, 1999 according to local laboratory procedures. In 
addition, semi-quantitative data using the culture quadrant assessment method will be 
collected for these pathogens.

APPENDIX C 
FDA Guidance for Industry: Toxicity Grading 
Scale for Healthy Adult and Adolescent Volunteers 
Enrolled in Preventive Vaccine Clinical Trials 
(September 2007) 
This guidance represents the Food and Drug Administration’s (FDA’s) current thinking 
on this topic. It does not create or confer any rights for or on any person and does not 
operate to bind FDA or the public. You can use an alternative approach if the approach 
satisfies the requirements of the applicable statutes and regulations. If you want to 
discuss an alternative approach, contact the appropriate FDA staff. If you cannot identify 
the appropriate FDA staff, call the appropriate number listed on the title page of this 
guidance. 
 
i. 
INTRODUCTION 
Preventive vaccines are usually developed to prevent disease in a healthy population. The 
Office of Vaccines Research and Review, Center for Biologics Evaluation and Research, 
regulates preventive vaccines under authority of section 351 of the Public Health Service 
Act (42 U.S.C. 262), as well as specific sections of the Federal Food, Drug, and Cosmetic 
Act, and reviews investigational new drug applications (INDs) and biologics license 
applications (BLAs). (See, for example, Title 21 Code of Federal Regulations (CFR) 
Parts 312, 600, and 601). Most of the clinical trials of preventive vaccines conducted to 
support INDs and BLAs enroll healthy volunteers in all phases of vaccine testing. The 
enrollment of healthy volunteers warrants a very low tolerance for risk in those clinical 
trials. 
 
This guidance provides you, sponsors, monitors, and investigators of vaccine trials, with 
recommendations on assessing the severity of clinical and laboratory abnormalities in 
healthy adult and adolescent volunteers enrolled in clinical trials. The grading system 
described in the table can also be useful in defining a particular study’s stopping rules 
(e.g., a certain number of AEs, as defined in the table, may call for stopping the study). 
Less extreme observations (e.g., mild) may not require discontinuing the study vaccine 
but can still contribute to evaluating safety by identifying parameters to focus upon in 
subsequent product development. Uniform criteria for categorizing toxicities in healthy 
volunteers can improve comparisons of safety data among groups within the same study 
and also between different studies. We, FDA, recommend using toxicity grading scale 
tables, provided below, as a guideline for selecting the assessment criteria to be used in a 
clinical trial of a preventive vaccine. We recommend incorporation of such appropriate, 
uniform, criteria into the investigational plan, case report forms, and study reports and 
correspondence with FDA, sponsors, monitors, investigators, and IRBs. 
 
This guidance finalizes the draft guidance of the same title dated April 2005 (70 FR 
22664, May 2, 2005). 
 
FDA’s guidance documents, including this guidance, do not establish legally enforceable 
responsibilities. Instead, guidances describe FDA’s current thinking on a topic and should 
be viewed only as recommendations, unless specific regulatory or statutory requirements

are cited. The use of the word should in FDA’s guidances means that something is 
suggested or recommended, but not required. 
 
ii. BACKGROUND 
Standardized toxicity assessment scales have been widely used to evaluate products 
treating specific diseases. For example, the National Cancer Institute’s Common Toxicity 
Criteria Scale and the Division of AIDS’ Toxicity Grading Scale standardize the 
evaluation of adverse events among patients with cancer and HIV/AIDS, respectively 
(Refs. 1, 2). The defined toxicity parameters in those scales are designed for patients who 
may already experience mild, moderate, or severe adverse clinical or laboratory events 
due to the disease process, and may not be appropriate for healthy volunteers. 
 
In the development of the toxicity grading scales for healthy volunteers, we chose 
parameter limit values based on published information, when such values were available 
(Refs. 1-6). For example, the Brighton Collaboration has developed case definitions and 
guidelines to evaluate some adverse events associated with administering vaccines (Ref. 
3). In some cases, parameter limit values were based on clinical experience and 
experience reviewing vaccine clinical trials that enroll normal healthy subjects. 
 
Toxicity grading scales for laboratory abnormalities should consider the local laboratory 
reference values when the parameter limit values are defined. The characterization of 
laboratory parameters among some populations of healthy adults and adolescents may 
require the exercise of clinical judgment, for example, consideration of the potential for 
ethnic differences in white blood cell (WBC) counts or gender differences in creatine 
phosphokinase (CPK) values. 
 
iii. TOXICITY GRADING SCALE TABLES 
Adverse events in a clinical trial of an investigational vaccine must be recorded and 
monitored and, when appropriate, reported to FDA and others involved in an 
investigation (sponsors, IRBs, and investigators). (See, for example, 21 CFR 312.32, 
312.33, 312.50, 312.55, 312.56, 312.60, 312.62, 312.64, and 312.66). Although the use of 
a toxicity grading scale for adverse events would not replace these regulatory 
requirements, using a scale to categories adverse events observed during a clinical trial 
may assist you in monitoring safety and making required reports. Nonetheless, we believe 
that categorization or grading of data as outlined in this document is supplementary to 
and should not replace full and complete data analysis. 
 
These guidelines for toxicity grading scales are primarily intended for healthy adult and 
adolescent volunteers. The parameters in the tables below are not necessarily applicable 
to every clinical trial of healthy volunteers. The parameters monitored should be 
appropriate for the specific study vaccine. For some preventive vaccines under 
development, it may be appropriate to include additional parameters to be monitored 
during a clinical trial or to alter the choice of values in the toxicity table. For example, 
additional parameters might be added based on one or more of the following: safety 
signals observed in pre-clinical toxicology studies, the biological plausibility of the 
occurrence of certain adverse events, or previous experience with a similar licensed 
product.

As discussed above, the tables do not represent a recommendation to monitor all the 
listed parameters in all clinical trials of healthy volunteers, nor do the tables represent all 
possible parameters to be monitored. In addition, these tables do not represent study 
inclusion or exclusion criteria. We recommend that the parameters monitored be 
appropriate for the study vaccine administered to healthy volunteers participating in the 
clinical trial. 
 
a. Tables for Clinical Abnormalities 
Note from the sponsor: The tables in this section of the guidance will not be used in this 
particular study. Instead, the parameters as provided in the NTHI-004 study protocol are 
to be used. 
 
b. Tables for Laboratory Abnormalities 
The laboratory values provided in the tables below serve as guidelines and are dependent 
upon institutional normal parameters. Institutional normal reference ranges should be 
provided to demonstrate that they are appropriate.

Co-ordinating author: 
PPD 
(XPE Pharma & Science for GSK 
Biologicals) 
Rationale/background for changes: 
Protocol amendment 1 was prepared: 
• 
Because the volumes of the individual blood samples that will be collected were 
re-distributed after discussion with the central laboratory. The total volume of 
blood collected per subject across scheduled visits and at AECOPD visits remains 
similar. 
• 
Because information on processing and storage temperature until shipment was 
updated for some of the samples after discussion with the central laboratory. 
• 
To clarify that the plasma obtained during PBMC processing will be kept for 
potential future additional testing. 
• 
To clarify that white blood cell differential count will be done on blood samples 
for safety assessment. 
In addition, some other, minor clarifications have been made and the list of 
contributing authors has been updated.

at each pre-defined timepoint and will be split and processed as follows: 
• 
Approximately 2 mL of whole blood will be collected for haematology assessment. 
These samples will not be processed They should be kept at room temperature and 
shipped on the day of collection. 
• 
Approximately 3.5 mL of whole blood will be collected for biochemistry assessment 
and will be processed to serum. After processing, serum samples should be kept at 
room temperature and shipped on the day of collection. 
 
(An) additional blood sample(s) for safety assessment may need to be drawn before 
administration of vaccine Dose 2, or during other study visits if deemed necessary by the 
investigator (see Table 10). These samples will not be processed. They should be kept at 
room temperature and shipped on the day of collection.

(XPE Pharma & Science for GSK 
Biologicals) 
Rationale/background for changes: 
Protocol amendment 2 was prepared: 
• 
To add clarification in the tertiary objectives: because acute exacerbations of 
COPD are complex events, triggered by multiple (interacting) pathogens, assessing 
the natural immunity to other pathogens might be important for interpretation of 
the data. 
• 
To add an additional blood sample for haematology assessment at each AECOPD 
visit. This blood sample will be collected to describe the systemic inflammation at 
time of exacerbation in terms of white blood cells and differential cell counts. 
• 
To clarify the list of concomitant medication that may lead to elimination of a 
subject from ATP analysis of immunogenicity (Section 7.6.2): because oral 
corticosteroids are commonly used in treatment of exacerbations, the 
administration of oral corticosteroids given for this indication will not fall under 
the definition of “chronic administration of immunosuppressants or other 
immune-modifying drugs at any time during the study period”, used to determine 
elimination from the ATP analysis of immunogenicity. 
• 
To add a benefit: risk assessment section (Section 1.3). 
In addition, a typo in the footnote of the table of intervals between visits (Table 9) has 
been corrected and the list of contributing authors has been updated.

Benefits considerations include: 
• 
Contribution to the process of developing of a vaccine against AECOPD. 
• 
Medical evaluations/assessments associated with this study (i.e. physical 
examination, blood testing [haematology and biochemistry data], spirometry). 
 
1.3.3 Overall Benefit : Risk Conclusion 
 
Taking into account the measures taken to minimize risks to subjects participating in 
this study, the potential and/or known risks identified in association with the candidate 
NTHi vaccine are justified by the anticipated benefits that may be afforded to patients 
for the prevention of AECOPD.

Rationale/background for changes: 
• 
In compliance with ICH requirements, the protocol mentions that all results will be 
presented in an integrated report at the end of the study. 
• 
Following re-development and re-validation of the anti-PD ELISA, a new cut-off 
was defined. 
• 
Reference to the GSK Biologicals’ Laval laboratory was removed, as this 
laboratory will not be used in the study. In addition, this laboratory is no longer 
part of GSK Biologicals’ laboratories. 
• 
Internal assay qualification procedures were revised and it was decided that the 
level of characterisation of the ELISA assays can be minimal (set-up level) for this 
study as immunogenicity data are descriptive. In consequence, the assays will be 
standardized but not qualified as stated in the original version.This change will not 
impact the validity of the results. 
• 
A tertiary endpoint was added as the presence of viral pathogens in sputum will be 
examined as part of microbiome analysis. 
• 
In order to see early effects of the vaccine on the microbiome, analysis on fresh 
sputum samples (culture results) will be done on all available data up to the data 
lock point of the interim analysis. 
• 
In order to have a first look whether or not the investigational vaccine has an 
impact on AECOPD, AECOPD analyses will be done up to the data lock point of 
the interim analysis. 
• 
Wording was added to clarify process for collection of sputum H. influenzae 
sweeps. 
• 
Wording was updated in order to be aligned with the Statistical Ananlysis Plan. 
• 
In addition, minor edits in other sections were made for clarification purposes.

Between groups evaluation 
The difference in terms of GMCs will be evaluated at 1 month post-Dose 2 by computing 
the 95% CIs of the GMC ratio between groups by using an one-way ANCOVA model 
that considers heterogeneity of variances (via Proc Mixed) on the logarithm10 
transformation of the concentrations on the logarithm10 transformation of the 
concentrations. This model e ANCOVA model will include country, the group, age 
category (40 - 59 years or 60 - 80 years), number of moderate and severe AECOPD in the 
year before vaccine Dose 1 (< 2 or  2), and GOLD grade (GOLD 2 or GOLD 3) and 
pre-Dose 1 concentration (as covariate) as fixed effects and the pre-Dose 1 
concentration as regressor. The groups will be considered significantly different if the 
95% CI for the GMC ratio between the 2 groups does not contain the value 1.

Sequence of analysis 
• 
The analyses of the impact of the investigational vaccine on AECOPD will be 
performed in parallel with the first step. This will include: 
 
the analyses of fresh sputum samples (culture) obtained up to the data lock 
point of the interim analysis. 
 
The analyses of AECOPD obtained up to the data lock point of the interim 
analysis. 
Individual listings will only be provided at this stage. An integrated final study 
report containing data from the entire study will be written at the end of the study 
and will be made available to the investigators. 
 
Appendix A Laboratory assays 
Humoral antibody responses 
Anti-PD antibodies 
Anti-PD antibodies will be determined using an ELISA assay developed by GSK 
Biologicals. Concentration of specific anti-PD antibodies will be determined, using 
in-house made reference serum. The current cut-off of the assay is 153 100 EL.U/mL. 
This assay will however be re-validated according to the latest validation standards and a 
new cut-off might be defined based on a precise and accurate limit of quantification. 
 
Viral pathogen identification and viral load 
Respiratory viral pathogens will be diagnosed by mean of a commercial and qualified 
multiplex PCR assay (RVP Fast, Luminex). 
Rhinovirus- and respiratory syncytial virus-specific real-time quantitative PCRs will be 
developed and qualified performed on a subset of sputum samples at GSK Biologicals 
or at a designated GSK Biological laboratory.
