Title
A 52-week, multicenter, randomized, double-blind, placebo-controlled 
study to assess the efficacy and safety of QAW039 when added to 
existing asthma therapy in patients with uncontrolled severe asthma.
Brief title
Study of efficacy and safety of QAW039 in male and female patients (≥12 
years) with severe asthma inadequately controlled with standard of care 
asthma treatment.
Sponsor and Clinical 
Phase
Novartis, Phase III.
Investigation type
Drug.
Study type
Interventional.
Purpose and rationale
The overall purpose of this study is to determine the efficacy and safety 
of QAW039 (150 mg and 450 mg once daily), compared with placebo, 
when added to GINA steps 4 and 5 standard-of-care (SoC) asthma 
therapy (GINA 2016), in patients with inadequately controlled severe 
asthma and high eosinophil counts (eosinophil count at Visit 1 
≥250 cells/µl).  Inadequate control is defined as partly controlled or 
uncontrolled asthma (GINA 2016).
The study will also determine the efficacy and safety of QAW039 (150 mg 
and 450 mg once daily), compared with placebo, in the overall study 
population.
The rationale for this approach is to determine whether QAW039 reduces 
the rate of moderate-to-severe asthma exacerbations in the subset of 
patients with severe asthma and high eosinophil counts (≥250 cells/µl) as 
well as in the overall study population regardless of eosinophil counts. 
Primary Objectives 
In patients with severe asthma and high eosinophil counts (≥250 cells/µl) 
receiving SoC asthma therapy, to demonstrate the efficacy (as measured 
by rate of moderate-to-severe asthma exacerbations) of at least one dose 
level of QAW039 (150 mg or 450 mg once daily), compared with placebo, 
at the end of the 52-week active-treatment epoch.
In patients with severe asthma receiving SoC asthma therapy, to 
demonstrate the efficacy (as measured by rate of moderate-to-severe 
asthma exacerbations) of at least one dose level of QAW039 (150 mg or 
450 mg once daily), compared with placebo, at the end of the 52-week 
active-treatment epoch.
Secondary Objectives
In patients with severe asthma and high eosinophil counts (≥250 cells/µl) 
receiving SoC asthma therapy:

To demonstrate the efficacy of at least one dose level of QAW039 
(150 mg or 450 mg once daily), compared with placebo, with respect 
to change from baseline in Asthma Quality of Life Questionnaire 
(AQLQ+12) scores at the end of the 52-week active-treatment epoch.

To demonstrate the efficacy of at least one dose level of QAW039 
(150 mg or 450 mg once daily), compared with placebo, with respect 
to change from baseline in Asthma Control Questionnaire-5 (ACQ-5) 

Novartis

Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
score at the end of the 52-week active-treatment epoch.

To demonstrate the efficacy of at least one dose level of QAW039 
(150 mg or 450 mg once daily), compared with placebo, with respect 
to change from baseline in pre-dose FEV1 at the end of the 52-week 
active-treatment epoch.

To assess the safety of QAW039 (150 mg and 450 mg once daily), 
compared with placebo, with respect to adverse events, 
electrocardiograms (ECGs), vitals sign, laboratory tests and 
hypersensitivity reactions.
In all patients with severe asthma receiving SoC asthma therapy:

To demonstrate the efficacy of at least one dose level of QAW039 
(150 mg or 450 mg once daily), compared with placebo, with respect 
to change from baseline in Asthma Quality of Life Questionnaire 
(AQLQ+12) scores at the end of the 52-week active-treatment epoch.

To demonstrate the efficacy of at least one dose level of QAW039 
(150 mg or 450 mg once daily), compared with placebo, with respect 
to change from baseline in Asthma Control Questionnaire-5 (ACQ-5) 
score at the end of the 52-week active-treatment epoch.

To demonstrate the efficacy of at least one dose level of QAW039 
(150 mg or 450 mg once daily), compared with placebo, with respect 
to change from baseline in pre-dose FEV1 at the end of the 52-week 
active-treatment epoch.

To assess the safety of QAW039 (150 mg and 450 mg once daily), 
compared with placebo, with respect to adverse events, 
electrocardiograms (ECGs), vitals sign, laboratory tests and 
hypersensitivity reactions.
Study design
This study uses a randomized, multicenter, double-blind, placebo-
controlled parallel-group study design in which QAW039 or placebo is 
added to GINA steps 4 and 5 asthma therapy.
The study will include: 

a Screening epoch of up to 2 weeks to assess eligibility; 

a Run-in epoch of approximately 2 weeks and a maximum of 6 
weeks to collect baseline data for efficacy variables and compliance 
with the Electronic Peak Flow/ eDiary device (if a patient experiences 
an asthma exacerbation during the run-in epoch, the run-in epoch 
must be extended to 6 weeks to permit for resolution of the asthma 
exacerbation before randomization.  The run-in epoch should only be 
extended beyond 2 weeks (+/- 5 days) for an asthma exacerbation.);

a Treatment epoch of 52 weeks; 

a Follow-up epoch of 4 weeks, investigational and drug-free, 
following the last dose of study drug.
Population
The study population will include approximately 846 males and females 
aged ≥12 years with inadequately controlled severe asthma (partly 
controlled or uncontrolled asthma on treatment at GINA steps 4 and 5).
Approximately 15% of the patients will be adolescents (aged ≥12 to <18 
years).
Approximately two thirds of randomized patients will have a blood 
eosinophil count ≥ 250 cells/µl and one third a blood eosinophil count < 
250 cells/µl.
Inclusion criteria

Data analysis
The primary variable for this study is the number of moderate-to-severe 
asthma exacerbations experienced by each patient per patient year of 
follow-up. The primary variable will be analyzed using a negative binomial 
regression model with the natural logarithm of the duration of follow-up as 
an offset variable, treatment group, randomization strata and region as 
fixed class effects, as well as the natural logarithm of the number of 
asthma exacerbations in the 12 months prior to screening and the 
baseline pre-dose FEV1 as continuous linear covariates. Missing data will 
be imputed assuming no further treatment effect versus placebo for 
QAW039 patients that discontinue treatment and are lost to follow-up due 
to (or following a treatment discontinuation due to) lack of efficacy, 
adverse events or death. In contrast a continued treatment effect for 
QAW039 patients being lost to follow-up for reasons likely to be unrelated 
to study treatment (e.g. lost to follow-up, withdrew consent) will be 
imputed.
The superiority of QAW039 over placebo will be considered confirmed if 
at least one of the four primary null hypotheses regarding the 
exacerbation rates is rejected in favor of the respective two-sided 
superiority alternative hypothesis. 
The familywise type I error rate will be controlled at the two-sided 5% 
level across the primary and key secondary null hypotheses using a 
closed testing procedure. In this closed testing procedure the primary null 
hypotheses about exacerbations for each dose and population act as 
gatekeepers for the key secondary null hypotheses for the same dose 
and population.
188 patients per arm in the subpopulation with blood eosinophils ≥ 250 
cells/μl and 282 patients per arm in the overall population corresponding

to a total sample size of 846 patients provide greater than 80% power for
demonstrating the superiority of each dose of QAW039 compared to 
placebo in the subpopulation with blood eosinophils ≥ 250 cells/μl and 
overall population. Treatment discontinuation rate of 15% by 1 year is 
assumed in the active treatment groups and the placebo group. No 
further treatment effect versus placebo has been assumed during the off-
treatment period. Additionally, the planned sample size will give 80% 
power for FEV1 for each dose in the subpopulation at the resulting local 
two-sided significance level of 1.625% and 90% power for each dose in 
the overall population at the resulting local two-sided significance level of 
0.698% once the respective primary null hypothesis has been rejected. It 
was assumed that QAW039 achieves a difference of 150 mL against 
placebo in FEV1 after 52 weeks for patients that remain on treatment. A 
SD of 380 mL was assumed for FEV1.
The key secondary variables of this trial are AQLQ+12, ACQ-5 and 
average of the two pre-dose FEV1 assessments at the end of the 52 
week treatment period. 
For each key secondary variable, QAW039 dose and population t he null 
hypothesis that the difference to placebo at week 52 is zero will be tested 
versus the two-sided alternative hypothesis that the treatment difference 
at week 52 ≠0 using analysis of covariance. Prior to analysis, missing 
values for key secondary variables will be imputed in a similar manner as 
for the primary variable.
Safety summaries will be primarily based on on-treatment data for the 
safety set with selected tables also presented for the all data after the first 
intake of study drug, while all databased safety data will be listed.

Introduction
1.1
Background
Asthma presents a major global health burden. Despite existing therapies, there is still 
significant unmet medical need in asthma, with an estimated 300 million people affected 
worldwide. The World Health Organization estimates that 15 million disability–adjusted life 
years are lost annually due to asthma, representing 1% of the total global burden. Annual 
worldwide deaths have been estimated at 250,000 (Masoli, et al 2004). Uncontrolled asthma 
has a prevalence of greater than 6 million patients worldwide. 
Severe asthma is defined as asthma that requires treatment with high dose inhaled 
corticosteroids (ICS) plus a second controller and/or systemic corticosteroids to prevent it 
from becoming "uncontrolled" or that remains "uncontrolled" despite this therapy. Severe 
asthma is a heterogeneous condition consisting of phenotypes such as eosinophilic asthma 
(Chung, et al 2014). This subgroup has also been defined as "refractory" asthma (Proceedings 
of the ATS workshop on refractory asthma 2000).
Recurrent exacerbations are a major problem in some patients with severe asthma and can 
predominate in the subgroup with eosinophilic airway inflammation (Haldar, et al 2009). A 
number of therapeutic interventions impact on eosinophilic airway inflammation as measured 
by sputum eosinophilia. These include inhaled and oral corticosteroids and a number of 
biologic therapies (including anti-IL-5, anti-IL-5R, anti-IgE, and anti-IL-4Rα therapies). 
Generally, when a therapeutic agent has successfully suppressed sputum eosinophil levels, 
evidence of efficacy, as measured by a reduction in asthma exacerbations, has also been 
demonstrated (Pavord, et al 2012; Nowak, et al 2015; Wenzel, et al 2013; Takaku, et al 2013). 
In more severe asthma, inhaled and oral corticosteroids may not be as effective in reducing 
sputum eosinophilia as they are in milder disease (Wenzel, et al 2005; Nair, et al 2009). 
Consequently, there remains a need for well tolerated, easily-administered, anti-inflammatory 
therapies with the capability of suppressing sputum eosinophilia and reducing asthma 
exacerbations, particularly, for those patients appearing to be steroid resistant.
Chemoattractant receptor-homologous molecule expressed on Th2 cells (CRTh2) is a receptor 
for prostaglandin D2 (PDG2) which is one of the major prostanoid inflammatory mediators 
identified in asthma.  QAW039 is a CRTh2 antagonist expected to provide benefit in asthma 
by binding to CRTh2 receptors on eosinophils, basophils, and T lymphocytes in the blood and 
tissues; thus, inhibiting migration and activation of these cells into the airway tissues and 
blocking the PGD2-driven release of Th2 cytokines (Chevalier, et al 2005). Since these are 
the major effector cells and soluble factors driving airway inflammation in asthma, treatment 
with QAW039 should result in a decrease in these parameters of airway inflammation as well 
as a clinical improvement in asthma.  In support of this premise are the results of Study 
CQAW039A2208: a randomized, placebo-controlled, 12-week sputum study of QAW039 
(225 mg BID), compared with placebo, in patients with severe eosinophilic asthma.  In this 
study, QAW039 demonstrated a fall in sputum eosinophils of 71% (geometric mean) after 12 
weeks treatment.  
Given published results with other asthma therapies in which a reduction in sputum 
eosinophils is associated with a reduction in asthma exacerbations (Haldar, et al 2009; Pavord, 

Novartis

et al 2012), and the observed reduction in sputum eosinophils in Study CQAW039A2208, it is 
postulated QAW039 will reduce the rate of asthma exacerbations.
1.2
Purpose 
The overall purpose of this study is to determine the efficacy and safety of QAW039 (150 mg 
and 450 mg once daily), compared with placebo, when added to GINA steps 4 and 5 standard-
of-care (SoC) asthma therapy (GINA 2016)†, in patients with inadequately controlled severe 
asthma and high eosinophil counts (eosinophil count at Visit 1 ≥250 cells/ µl).  Inadequate 
control is defined as partly controlled or uncontrolled asthma (GINA 2016).
The study will also determine the efficacy and safety of QAW039 (150 mg and 450 mg once 
daily), compared with placebo, in the overall study population.  
This approach will permit the determination of the effect of QAW039 in reducing asthma 
exacerbations in the subset of patients with severe asthma and high eosinophil counts as well 
as in the overall study population regardless of eosinophil counts.

Investigational plan
3.1
Study design
This study uses a randomized, multicenter, double-blind, placebo-controlled parallel-group 
study design in which QAW039 or placebo is added to GINA steps 4 and 5 asthma therapy 
(Figure 3-1).  
Within 14 days prior to or at Visit 1, an informed consent will be obtained from patients 
before any study related assessments or procedures are performed. All patients signing 
informed consent must be registered in the Interactive Response Technology (IRT). Asthma 
and other medications and eligibility criteria will be reviewed. Patients will be instructed 
regarding medications to be withheld prior to spirometry for Visit 101 (See Section 5.5.8).
Approximately 2400 patients will be screened to randomize 846 patients into this study.
The study will include: 

a Screening epoch of up to 2 weeks to assess eligibility; 

a Run-in epoch of approximately 2 weeks and a maximum of 6 weeks to collect baseline 
data for efficacy variables and compliance with the Electronic Peak Flow/ eDiary device
(if a patient experiences an asthma exacerbation during the run-in epoch, the run-in epoch 
must be extended to 6 weeks to permit for resolution of the asthma exacerbation before 
randomization.  The run-in epoch should only be extended beyond 2 weeks (+/- 5 days) 
for an asthma exacerbation.);

a Treatment epoch of 52 weeks; 

a Follow-up epoch of 4 weeks, investigational and drug-free, following the last dose of 
study drug. Note: the follow-up epoch applies to all patients except those patients who 
enter the safety study directly after Visit 299.

Study design
Upon completion of the run-in epoch, all patients who met the eligibility criteria will be 
randomized to 1 of 3 treatments (QAW039 [150 mg or 450 mg once daily] or placebo once 
daily) in a ratio of 1:1:1.  Randomized patients will stratified according to their peripheral 
blood eosinophil counts (<250 cells/l or ≥250 cells/l), patient age (<18 years or ≥18 years),
and their baseline use or non-use of oral corticosteroids as part of their SoC asthma therapy at 
Visit 1.  Clinic visits will be scheduled approximately 4 weeks after randomization and then at 
approximately 8-week intervals during the active-treatment epoch.  Phone calls will occur at 
specified time points between visits occurring at 8-week intervals (see schedule of 
assessments Table 6-1).  A follow-up visit will occur approximately 4 weeks (i.e., 
approximately 30 days) following the last dose of study therapy to complete safety 
assessments and pregnancy testing (if applicable). Please refer to the assessment schedule 
(Section 6) for a list of procedures to be conducted at each visit.
A Safety Study of QAW039 is planned.  At sites participating in the Safety Study, patients 
who successfully complete 52 weeks of treatment in this study (Study A2307) may be offered 
participation in the Safety Study; patient participation in the Safety Study will be optional. 
The study design and procedures for the Safety Study will be described in a separate protocol.
Note: 
Patients experiencing an asthma exacerbation during the run-in epoch should receive 
treatment for their exacerbation, and remain in the run-in epoch until the subject has returned 
to their baseline asthma status for at least 2 weeks (2 weeks=14 days). If patients do not return 
to their baseline status for at least 2 weeks prior to Visit 199, patients will not be eligible for 
randomization and will be designated a run-in failure.
In addition to periodic unblinded safety reviews by an independent Data Monitoring 
Committee, a single futility interim analysis is planned as described in Section 3.5.

3.2
Rationale of study design
This randomized, double-blind, parallel-group, placebo-controlled, design supports the 
assessment of efficacy as well as safety of QAW039 as add-on treatment for patients with 
inadequately controlled severe asthma otherwise treated according to GINA 2016 (steps 4 and 
5) guidelines. According to GINA guidelines, the goals of asthma therapy are to attain asthma 
control and reduce future risk of asthma worsening while maintaining minimal side effects of 
therapy.  By maintaining good asthma control in patients with appropriate use of therapies, 
potential future risk to patients may be reduced. The endpoints included in this study measure 
symptomatic and objective parameters of asthma control (symptomatic parameters: daytime 
and nighttime asthma symptoms, SABA use, quality of life, Asthma Control Questionnaire 
[ACQ] scores; objective: lung function [FEV1, peak flow]) and future risk (moderate-to-
severe asthma exacerbations, longitudinal lung function) in patients at the end of 52 weeks of 
therapy.  
Patient population 
The overall purpose of this study is to determine the efficacy and safety of QAW039 (150 mg 
and 450 mg once daily), compared with placebo, when added to GINA steps 4 and 5 standard-
of-care (SoC) asthma therapy (GINA 2016), in patients with inadequately controlled severe 
asthma and high eosinophil counts (eosinophil count at Visit 1 ≥250 cells/µl).  The study will 
also determine the efficacy and safety of QAW039 (150 mg and 450 mg once daily), 
compared with placebo, in the overall study population.
A prior study of QAW039 (Study CQAW039A2208) demonstrated QAW039 (225 mg BID), 
compared with placebo, caused a reduction in sputum eosinophils in patients with severe 
eosinophilic asthma.  Given published results with other asthma therapies in which a 
reduction in sputum eosinophils is associated with a reduction in asthma exacerbations 
(Haldar, et al 2009; Pavord, et al 2012), and the observed reduction in sputum eosinophils in 
Study CQAW039A2208, it is postulated QAW039 will reduce the rate of asthma 
exacerbations.  Further, recent published results of the MENSA study (Ortega, et al 2014), in 
which the included patient population is similar to that proposed for the current study of 
QAW039, suggest patients with severe asthma, particularly those with severe eosinophilic 
asthma, are at risk for recurrent asthma exacerbations.  Taken together, the patient population 
for the current study is appropriate to evaluate the effect of QAW039 on reduction in rate of 
asthma exacerbations when patients stratified by eosinophil counts.
Screening epoch 
The screening epoch allows for assessment of patient entry criteria and for patients to become 
familiar with spirometry measurement and daily eDiary entry prior to the collection of 
baseline values. 
Run-in epoch 
The run-in epoch allows for patients to become familiar with administration of investigational 
treatment, to determine patient’s level of asthma control based on ACQ score (for eligibility),
and to collect baseline data for all efficacy variables.  This epoch will also assess patients’ 
compliance with an Electronic Peak Flow/ eDiary device and treatment.

Treatment epoch 
During this epoch oral QAW039 (150 mg and 450 mg) or placebo (1:1:1) will be 
administered once daily for 52 weeks, with the last dose given at Week 52 and final 
assessment for the treatment period at week 52. A 52-week study duration is necessary to 
minimize the impact of the seasonal variation on the primary endpoint, the rate of asthma 
exacerbations. Since one of the secondary endpoints is predose FEV1, patients will receive 
witnessed doses of study drug at clinic visits after spirometry is performed for the FEV1 
assessment.  This will allow for appropriate assessment of predose FEV1 prior to dosing.
Follow-up epoch 
The 4 week wash out epoch will monitor the safety and tolerability profile after the last dose 
of study drug. Note: the follow-up epoch applies to all patients except those patients who 
enter the safety study directly after Visit 299.
3.3
Rationale of dose/regimen, route of administration and duration 
of treatment
QAW039 will be administered at doses of 150 mg and 450 mg once daily as oral film-coated 
tablets (FCTs) in this study. 
A 450 mg once daily dose was selected for inclusion in the study based on the following:

At a dose of 450 mg once daily, >98% receptor occupancy is expected for the entire 
dosing interval in a “typical patient” at steady state allowing inhibition of eosinophil 
migration over the entire treatment interval.

A 500 mg once daily dose of QAW039 was efficacious on the endpoint of pre-dose FEV1 
in a sub-set of patients with percent predicted FEV1 <70% at baseline in Study 
CQAW039A2201 (proof-of-concept study). A 450 mg total daily dose was also 
efficacious on the endpoint of pre-dose FEV1 in study CQAW039A2206.

A total daily dose of 450 mg (225 mg twice daily) was evaluated in Study 
CQAW039A2208 in patients with severe asthma as add-on to SoC asthma therapy.  In this 
study, QAW039 caused significant reduction of sputum eosinophilia in patients with 
severe eosinophilic asthma.  The reduction in sputum eosinophils was comparable to that 
observed with the anti-IL5 antibodies, Mepolizumab (Pavord, et al 2012) and Reslizumab 
(Castro, et al 2011 and 2015).  An association between reduction of eosinophilic airway 
inflammation and frequency of exacerbations has been reported in the literature (Haldar, et 
al 2009; Pavord, et al 2012; Nowak, et al 2012; Wenzel, et al 2013; Takaku, et al 2013), 
suggesting QAW039 may also cause a reduction in the frequency of asthma exacerbations 
in patients with severe refractory eosinophilic asthma.
The dose of 150 mg once daily was selected for inclusion in the study because it was the 
lowest dose of QAW039 with “maximal efficacy” on the endpoint of FEV1 in a prior dose-
ranging study (Study CQAW039A2206) in patients with moderate-to-severe asthma (GINA 
treatment steps 4 and 5) as add-on to low-dose ICS.  This dose is ½ log lower than highest 
dose. 
Since the QAW039 dose of 150 mg was considered the optimal dose (i.e., lowest dose 
providing maximal efficacy) in a prior dose-ranging study, doses lower than 150 mg will not 
be included in this study.

3.4
Rationale for choice of comparator
All patients in this study will continue to receive their asthma medications as background 
treatment. QAW039 or placebo will be administered as add-on therapy.
The use of placebo will permit the assessment of improvement in terms of incidence of 
moderate-to-severe asthma exacerbations for patients with uncontrolled disease who are 
treated with QAW039, in comparison to those continuing solely on existing SoC asthma 
therapy.  Additionally, the use of placebo will permit a controlled evaluation of the safety of 
QAW039 in these patients.
This study does not include an active comparator since QAW039 will be given as add -on 
therapy to standard of care asthma therapy in patients with severe asthma (GINA treatment 
steps 4 and 5).
3.5
Purpose and timing of interim analyses/design adaptations
An independent Data Monitoring Committee (see Section 8.3) will conduct periodic 
unblinded safety reviews of the accumulating data (including specific safety summaries for 
adolescent participants) from this trial and other Phase III trials of the QAW039 asthma 
development program to ensure safety of trial participants. 
In addition, a single interim analysis for futility will be conducted to assess whether the study 
should be stopped for futility or safety, or whether treatment in one or more QAW039 d ose 
groups should be discontinued for safety reasons. There will be no stopping for demonstrated 
efficacy prior to the completion of the study at either the unblinded safety reviews or the 
futility interim analysis, because a sufficiently large safety dataset is needed in addition to 
efficacy data.  Therefore, no statistical adjustment will be made to the final analysis.
This interim analysis for futility will occur when approximately 200 patient-years of follow-
up data have accumulated.  The timing of the futility interim analysis may be modified based 
on the progress of recruitment, the logistics of arranging DMC meetings, the data accrual in 
other QAW039 asthma Phase III trials and additional external data that might become 
available. 
3.6
Risks and benefits
QAW039 is a potent and highly selective oral CRTh2 receptor antagonist being developed as 
a potential therapy treatment for patients with severe asthma.  CRTh2 is a receptor for PGD2
which mediates the activation and migration of Th-2 cells and eosinophils, some of the key 
inflammatory cell types in asthma.  Recruitment of these cells into the lung is partly 
responsible for the intermittent airway obstruction which leads to wheezing and shortness of 
breath characteristic of asthma.
QAW039 is at least 300-fold selective for the CRTh2 receptor compared to other available 
prostanoid receptors and to cyclooxygenase-1 and cyclooxygenase-2, and it has been 
demonstrated to be a potent in vitro inhibitor of human whole blood eosinophil activation and 
induction of Th-2 cytokines. After oral dosing in rats, QAW039 inhibited pulmonary 
eosinophilia induced by the PGD2 metabolite DK-PGD2. 
The potential benefits of QAW039 therapy need to be balanced against its potential risks. The 
risk to patients in this study will be minimized by compliance with the inclusion/exclusion

criteria and close clinical monitoring. All patients will remain on the background SoC asthma 
therapy they were taking at screening throughout the study.  Furthermore, patients will be 
instructed how to react to worsening of asthma symptoms so patients can be managed 
appropriately.
The overall clinical experience with QAW039 includes 12 studies: 10 (6 in healthy volunteers 
and 4 in patients) have completed and 2 (in patients) are ongoing. The completed phase 2 
studies consist of 3 in patients with asthma and 1 in patients with allergic rhinitis. The 
ongoing phase 2 studies include one study in patients with asthma (CQAW039A2214) and 1 
study in patients with atopic dermatitis (CQAW039X2201). 
As of January 2015, over 1300 subjects have been exposed to QAW039 in the clinical 
program. In the completed studies of QAW039, 1239 subjects (175 healthy volunteers and 
1064 patients with asthma or allergic rhinitis) received QAW039, 342 subjects received 
placebo, and 359 subjects received other treatment (rosuvastatin, simvastatin or montelukast).
QAW039 has been well tolerated in populations studied to date at total daily doses up to 500 
mg given for up to 12 weeks. In the 10 completed studies, 16 patients reported 17 serious 
adverse events (SAEs), no deaths due to SAEs were reported, and 5 discontinuations due to 
SAEs were reported. Of the 16 patients reporting SAEs, 12 patients reported 13 events, 2 
patients reported 2 events and 2 patients reported 2 events in the QAW039, placebo, and 
montelukast treatment groups, respectively. There were no SAEs with a suspected causal 
relationship to QAW039. There have been no adverse events of idiopathic drug reactions. 
Overall, the safety profile of QAW039 has been favorable across studies.
Three Phase 2 studies in patients with asthma demonstrated the effect of QAW039 across the 
range of asthma severities (mild to severe). Below is a summary of efficacy data from these 3 
completed studies in asthma. For detailed information on the studies described below, please 
refer to the Investigators Brochure.
Study A2201 (proof-of-concept [PoC] study) 
Study A2201 was a PoC study in 170 corticosteroid-free, atopic, asthmatic patients 
uncontrolled on as needed β-agonist medication who were randomized (1:1) to receive 
QAW039 500 mg or matching placebo for 28 days.  The primary objective was to assess the 
efficacy of QAW039, compared with placebo, as measured by trough FEV1 after 28 days of 
treatment. Overall benefit for QAW039 treatment was not demonstrated in the entire study 
population (patients with percent predicted FEV1 of 60% to 85% at baseline) compared with 
placebo treatment. Benefit occurred only in those patients with more severe baseline airflow 
obstruction (FEV1 < 70% predicted). Results from Study A2201 demonstrated 4 weeks of 
treatment with QAW039 (500 mg q.d.) improved both lung function (FEV1: 207 ml > placebo 
group, p=0.002, 1-sided test) and control of asthma symptoms (ACQ: 0.41 points < placebo 
group, p=0.009, 1-sided test) in the subset of patients with moderate airflow obstruction at 
baseline (FEV1 < 70% predicted) who were inadequately controlled on reliever medication 
alone.
Study A2206 (dose-ranging study) 
Study A2206 was a randomized, placebo-controlled, multi-center, dose-ranging study in 
patients with moderate-to-severe allergic asthma inadequately controlled by ICS therapy.

Patients who satisfied selection criteria were randomized to 1 of 15 treatment arms (13 
QAW039 treatment arms, 1 montelukast positive control arm and 1 placebo arm) for 12 
weeks followed by a single-blind, placebo wash-out period for 4 weeks. The primary 
objective of the study was to assess the efficacy of QAW039, compared with placebo, as 
measured by trough FEV1 after 12 weeks of treatment.  A total 1058 patients were 
randomized to the following treatment groups: 139 patients to montelukast, 137 patients to 
placebo and 782 patients to QAW039.  The study achieved its primary endpoint by 
demonstrating a clinically and statistically significant improvement (0.112 L; p=0.0035) in 
trough FEV1 after 12 weeks therapy with QAW039, compared with placebo, in a population 
of moderate-to-severe, persistent, atopic asthmatics with a predicted baseline, pre-
bronchodilator FEV1 of 40% to 80% of the predicted value who were uncontrolled on low 
dose ICS.
Results showed the greatest differences from placebo occurred at doses of 75 mg twice daily 
and 150 mg once daily. These doses were towards the middle of the 1 mg to 450 mg dose 
range tested. There appeared to be little difference between once daily and twice daily dosing.  
There were no significant changes compared with placebo in ACQ, AQLQ or Juniper asthma 
control diary scores across the study population either for QAW039 or the positive control, 
montelukast.  Examination of sub-groups did not provide evidence of increased efficacy for 
QAW039, compared with placebo, in terms of FEV1.
Study A2208 
Study A2208 was a single site, double-blind, placebo-controlled study to determine whether, 
in patients with sputum eosinophilia (≥ 2%) and persistent, moderate-to-severe asthma, 12 
weeks of treatment with QAW039 at a dose of 225 mg twice daily, compared with placebo, 
on top of SoC asthma treatment would reduce levels of eosinophils in induced sputum.  In 
addition to measurements of changes in sputum eosinophilia (primary endpoint) and ACQ 
(secondary endpoint), a very wide range of lung function, patient reported outcome, imaging, 
histological, proteomic and transcriptional endpoints were also measured.
A total of 61 patients were randomized and 55 patients completed their assigned double-blind 
treatment period.  The primary endpoint of the study was achieved. The level of sputum 
eosinophilia decreased by 71% (geometric mean) from baseline after 12 weeks treatment with 
QAW039.  This fall was significantly different from the change observed in placebo-treated 
patients (p=0.0007).  QAW039 led to clinically and statistically relevant asthma control (as 
measured by the ACQ test) in patients uncontrolled at baseline (i.e. baseline ACQ7≥1.5), with 
the ACQ7 improving by 0.58 points (p=0.0473) in the per-protocol population. In the overall 
population, the ACQ7 score improved by 0.40 points (p=0.0843). There was a clinically (0.5 
point) and statistically significant improvement in QoL, as measured by the AQLQ overall 
score, after 12 weeks treatment with QAW039 in comparison to placebo (treatment difference 
= 0.593 point; p=0.0080). The proportion of patients experiencing a moderate or severe 
asthma exacerbation was similar across the two treatment groups (7 in the QAW039 group 
and 6 in the placebo group).  This finding was not surprising given the study was small and of 
limited duration and, therefore, was not designed to detect an effect on this endpoint.  
Numerical increases were seen in pre-bronchodilator FEV1 in QAW039-treated patients 
regardless of whether absolute volume or % change was considered. The greatest increases 
were observed in those per protocol-treated patients whose predicted FEV1 was <70% at 
baseline (190 mL and 13.409% for volume and % change, respectively). However, none of 

Novartis

these results were statistically significant.  Given the results with other therapies (a reduction 
in sputum eosinophils is associated with a reduction in asthma exacerbations), and the 
observed reduction in sputum eosinophil numbers in the prior study of QAW039, it is 
postulated QAW039 will reduce the rate of asthma exacerbations in the current study.  
Therefore, the main purpose of the current study is to definitively demonstrate the effect of 
QAW039 on reduction in the rate of moderate-to-severe asthma exacerbations. 
Cardiovascular risks:
Transient, increases in heart rate were observed in a cardiovascular safety pharmacology study 
in dogs. These changes were not associated with any significant alterations in blood pressure, 
ECG interval duration, morphology or rhythm or any structural changes in cardiac tissues.  No 
cardiac findings have been identified in the healthy volunteer and patient studies completed to 
date apart from an observed imbalance in the frequency of post-randomization cardiac adverse 
events in study CQAW039A2206 with a higher incidence in the QAW039 treatment group 
(1.7%) compared with either placebo (0.7%) or montelukast (0%) treated patients. The cardiac 
events comprised a number of different non-serious arrhythmias and one serious adverse 
event of pericarditis not suspected to be related to study drug by the investigator. Three of the 
events in the QAW039 treatment groups occurred during the washout period and 9 resolved 
on treatment. Based on the inability to identify discernable trends with QAW039 dose, 
regimen, time-of-onset, patient age and gender, concomitant medication, event type and 
following detail ECG review, it was considered that these were most probably coincidental 
events without a causal association to study drug.
A formal QTc study has not been completed for QAW039. Monitoring for changes in vital 
signs, ECGs and biochemical parameters will be conducted.
Liver toxicity:
Dose-dependent increases in liver weights with concomitant hepatocellular hypertrophy were 
the primary findings during 2- and 13-week toxicity studies in mice. These changes were 
considered to be a species-specific adaptive metabolic response with no relevance for humans.
Liver toxicity findings have not been identified in the healthy volunteer and patient studies 
completed to date.  Monitoring of liver function tests will be conducted as described in 
Appendix 2 of this protocol.
Potential risk of idiosyncratic drug reactions
CCN362 is an acylglucuronide metabolite of QAW039 and its potential to covalently bind to 
plasma proteins, such as albumin, was demonstrated in the human ADME (Absorption, 
distribution, metabolism, and excretion) study of QAW039 (CQAW039A2104). In the 
literature, in vivo binding of acyl glucuronides to proteins has been reported to be associated 
with rare idiosyncratic drug reactions (IDRs), although a causal connection of protein 
adduction to IDRs remains uncertain (Regan, et al 2010).  There have been no IDRs observed 
with QAW039 treatment in completed clinical trials.  Surveillance of adverse events for 
identification of IDRs will be conducted.

Drug-drug interactions
QAW039 and CCN362 did not show any relevant inhibition or induction of the cytochrome 
P450 isoenzymes or inhibition of ubiquitous efflux transporters. The most potent in vitro 
inhibition by QAW039 was found for OATP1B1, but clinically only a small impact was 
observed at 450 mg/day (~2-fold increase in Cmax of simvastatin acid and rosuvastatin 
without change in AUC).  Based on these data, as well as recommendations in the simvastatin 
label, simvastatin doses of > 20 mg per day should not be co-administered with QAW039; no 
relevant impact on the disposition of other co-medications are expected with QAW039 dosed 
up to 450 mg/day.   Patients on doses of simvastatin >20 mg, doses of atorvastatin >40 mg,
doses of pravastatin >40mg, or doses of pitavastatin >2 mg per day (Elsby et al 2012, Deng et 
al 2008, Noe et al 2007, and Kalliokoski et al 2009), as well as patients on any statins with 
high CK levels (>2 X ULN) at screening (Visit 1) will be excluded from the study (see 
Section 4.2). Furthermore, patients on statin medication who are included in the study will 
have regular monitoring for relevant symptoms and be subject to discontinuation based on 
persistent myalgia and blood CK levels (Jacobson 2008) as described in Section 5.5.10.

Population
The study population will include approximately 846 males and females aged ≥12 years with 
inadequately controlled severe asthma (partly controlled or uncontrolled asthma on treatment 
at GINA steps 4 and 5). Approximately 15% of the patients will be adolescents (aged ≥12 to 
<18 years).
Patients will be stratified based on blood eosinophil counts at Visit 1, so that approximately
two thirds of randomized patients will have a blood eosinophil count ≥ 250 cells/µl and one 
third a blood eosinophil count < 250 cells/µl at Visit 1. It is anticipated at least 2400 patients 
will need to be screened to randomize approximately 846 patients into the study. It is 
estimated that approximately 15% of patients will discontinue their investigational treatment
during the treatment epoch; these patients will not be replaced.

Additional study treatment
No additional maintenance asthma treatment beyond investigational treatment is requested for 
this trial.
All 
patients 
will 
be 
provided 
with 
short-acting 
β2-agonists
(SABAs)
(salbutamol/albuterol/other SABA) which they will be instructed to use throughout the study 
as rescue medication on an ‘as needed basis.’
Short-acting β2-agonists will either be supplied to the investigator sites locally by Novartis or 
be provided by the study center and reimbursed by Novartis.
5.2
Treatment arms
During the run-in epoch, all patients will receive placebo to QAW039 once daily (one tablet 
blinded placebo to QAW039 150 mg and one tablet blinded placebo to QAW039 450 mg).
Patients will be assigned to one of three treatment arms as follows in a 1:1:1 ratio in the 
treatment epoch:

QAW039 150 mg once daily (one tablet of blinded QAW039 at 150 mg dosage 
strength to be given together with one tablet blinded placebo to QAW039 450 mg)

QAW039 450 mg once daily (one tablet of blinded QAW039 at 450 mg dosage 
strength to be given together with one tablet blinded placebo to QAW039 150 mg)

Placebo to QAW039 once daily (one tablet blinded placebo to QAW039 150 mg and 
one tablet blinded placebo to QAW039 450 mg)
Patients will be instructed to take their investigational treatment (QAW039 or placebo) once 
daily in the morning without regard to time of food intake.
5.3
Treatment assignment, randomization
At Visit 201, all eligible patients will be randomized via Interactive Response Technology 
(IRT) to 1 of the 3 treatment arms (QAW039 150 mg or 450 mg once daily or placebo once 
daily) in a 1:1:1 fashion within each of the randomization strata (peripheral blood eosinophil 
counts at Visit 1(<250 cells/l or ≥250 cells/l), patient age (<18 years or ≥18 years), and 
their use or non-use of oral corticosteroids as part of their SoC asthma therapy) by IRT. The 
investigator or his/her delegate will contact the IRT after confirming that the patient fulfills all 
the inclusion/exclusion criteria. The IRT will assign a randomization number to the patient, 
which will be used to link the patient to a treatment arm and will specify a unique medication 
number for the packages of investigational treatment to be dispensed to the patient. The 
randomization number will not be communicated to the caller.
The randomization numbers will be generated using the following procedure to ensure that 
treatment assignment is unbiased and concealed from patients and investigator staff. A patient 
randomization list will be produced by the IRT provider using a validated system that 
automates the random assignment of patient numbers to randomization numbers. These 
randomization numbers are linked to the different treatment arms, which in turn are linked to 
medication numbers. A separate medication list will be produced by or under the 
responsibility of Novartis Drug Supply Management using a validated system that automates 
the random assignment of medication numbers to packs containing the investigational drug(s).

Randomization will be stratified by peripheral blood eosinophil counts at Visit 1 (<250 
cells/l or ≥250 cells/l), patient age (<18 years or ≥18 years), and patient use or non-use of 
oral corticosteroids as part of their SoC asthma therapy.
Treatment randomization will be 
stratified at the regional level.
Note: Enrollment to patient strata may be restricted by the Sponsor prior to the end of overall 
recruitment in order to achieve the desired distribution in the trial population.
The randomization scheme for patients will be reviewed and approved by a member of the 
Novartis Randomization Group.
5.4
Treatment blinding
This study consists of a single-blind run-in epoch (i.e., only patients will be blinded to the 
identity of the treatment) followed by a double-blind randomized treatment epoch. 
Patients, investigator staff, persons performing the assessments, and data analysts will remain 
blind to the identity of the treatment from the time of randomization until database lock, using 
the following methods: (1) Randomization data are kept strictly confidential until the time of 
unblinding, and will not be accessible by anyone involved in the study 
 
 
 
 
 (2) For each dose level, the identity of the 
treatments will be concealed by the use of placebos identical in packaging, labeling, schedule 
of administration, appearance, taste, and odor to QAW039. Across the doses, a double-
dummy design will be used.
Unblinding should only occur in the case of patient emergencies and at the conclusion of the 
study. In addition, the independent DMC will be unblinded for the purpose of safety reviews 
and at the time of the futility interim analysis.
5.5
Treating the patient 
5.5.1
Patient numbering 
Each patient is uniquely identified by a Subject Number which is composed by the site 
number assigned by Novartis and a sequential number assigned by the investigator. Once 
assigned to a patient, the Subject Number will not be reused.  If a patient is re-screened they 
will be assigned a new subject number.
Upon signing the informed consent form, the patient is assigned the next sequential number 
by the investigator. The investigator or his/her staff will contact the IRT and provide the 
requested identifying information for the patient to register them into the IRT. The site should 
select the CRF book with a matching Subject Number from the EDC system to enter data. 
If the patient fails to be treated for any reason, the IRT must be notified within 2 days that the 
patient was not treated. The reason for not being treated will be entered on the Screening 
Epoch Study Disposition CRF.
5.5.2
Dispensing the investigational treatment

Novartis
Confidential
Page 40
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
Each study site will be supplied by Novartis with investigational treatment in packaging of 
identical appearance.
The investigational treatment packaging has a 2-part label. 
A unique randomization medication number is printed on each part of this label which 
corresponds to the study epoch and/or treatment arm the patient is assigned to.
Investigator staff will identify the investigational treatment package(s) to dispense to the 
patient by contacting the IRT and obtaining the medication number(s). Immediately before 
dispensing the package to the patient, investigator staff will detach the outer part of the label 
from the packaging and affix it to the source document (Drug Label Form) for that patient’s 
unique subject number. 
5.5.3
Handling of study treatment 
5.5.3.1
Handling of investigational treatment
The investigational treatment must be received by a designated person at the study site, 
handled and stored safely and properly, and kept in a secured location to which only the 
investigator and designees have access. Upon receipt, all investigational treatment should be 
stored according to the instructions specified on the labels. Clinical supplies are to be 
dispensed only in accordance with the protocol. Technical complaints are to be reported to the 
respective Novartis CPO Quality Assurance.
Medication labels will be in the local language and comply with the legal requirements of 
each country. They will include storage conditions for the investigational treatment but no 
information about the patient except for the medication number.
The investigator must maintain an accurate record of the shipment and dispensing of 
investigational treatment in a drug accountability log. Monitoring of drug accountability will 
be performed by the field monitor during site visits and at the completion of the trial. Patients 
will be asked to return all unused investigational treatment and packaging at the end of the 
study or at the time of discontinuation of investigational treatment. 
At the conclusion of the study, and as appropriate during the course of the study, the 
investigator will return all unused investigational treatment, packaging, drug labels, and a 
copy of the completed drug accountability log to the Novartis monitor or to the Novartis 
address provided in the investigator folder at each site.
5.5.3.2
Handling of other study treatment 
No applicable.
5.5.4
Instructions for prescribing and taking study treatment
Study treatment will be single-blind during the run-in and double-blind, double-dummy, and 
placebo-controlled after randomization. At clinic visits, patients will receive a witnessed dose 
of study medication.  These in-clinic witnessed doses will be given after the completion of all 
pre-dose assessments (see Section 6) and should be given at approximately the same time at 
each clinic visit.  Between clinic visits, patients will take study medication once daily in the 

Novartis
Confidential
Page 41
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
morning.  Patients will be instructed to take their study medication at approximately the same 
time each morning.
At Visit 101, all eligible patients will be given oral placebo to QAW039 for a run-in epoch of 
2 weeks and will be instructed on the intake of the investigational treatment. In order to 
maintain the blind from the patient’s point of view, investigators should not divulge 
information regarding the fact that all individuals will be assigned to placebo during the 
run-in epoch. If a patient experiences an asthma exacerbation during the run-in epoch, the 
run-in epoch must be extended up to 6 weeks to permit for resolution of the asthma 
exacerbation before randomization. The run-in epoch should only be extended beyond 2 
weeks (+/- 5 days) for an asthma exacerbation. At Visit 201, patients will be randomized and 
stratified according to their peripheral blood eosinophil counts (<250 cells/l or ≥250 cells/l), 
patient age (<18 years or ≥18 years), and their baseline use or non-use of oral corticosteroids 
as part of their SoC asthma therapy at Visit 1. Each randomized patient will then enter a 52-
week treatment epoch where they will receive one of the following 3 treatments:  (i) QAW039 
150 mg once daily or (ii) QAW039 450 mg once daily or (iii) placebo once daily given on top 
of their individual background asthma treatment. The investigational treatment will be 
dispensed in medication packs (bottles) at each site visit during the treatment epoch to cover 
the treatment period between patient visits and to allow for late visits and other unforeseen 
events. All dosages prescribed and dispensed to the patient and all dose changes during the 
study must be recorded on the Dosage Administration Record CRF
All kits of investigational treatment assigned by IRT will be recorded/databased in the IRT. 
The investigator should instruct the patient to take the investigational treatment exactly as 
prescribed in order to ensure compliance. The patient should be instructed to contact the 
investigator if he/she is unable for any reason to take the investigational treatment as 
prescribed. 
5.5.5
Permitted dose adjustments and interruptions of study treatment
QAW039 treatment dose adjustments are not permitted.
QAW039 treatment interruption is only permitted in the following situations:

A positive urine pregnancy test requires immediate interruption of study medication 
until serum β-hCG is performed and found to be negative. 

An investigator considers an interruption is necessary for the treatment of an adverse 
event. 
Interruption to treatment must be recorded on the Dosage Administration Record CRF.
5.5.6
Rescue medication
At Visit 1 all patients will be provided with a SABA (such as salbutamol [100 mcg or 
albuterol 90 mcg]) which they will be instructed to use throughout the study as rescue 
medication on an ‘as needed basis’. Patients will be advised that between visits they can take 
their rescue medication for symptoms of asthma. Rescue medication (i.e., SABAs) will either
be supplied to the investigator sites locally by the Novartis CPO or provided by the study 
center and reimbursed by Novartis.
Nebulized salbutamol/albuterol is not allowed as rescue medication and will not be supplied.

Novartis
Confidential
Page 42
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
To standardize measurements, patients will be instructed not to use their rescue medication 
upon rising in the morning on days requiring spirometric assessments indicated in Table 6-1, 
unless absolutely necessary.  If rescue medication is taken within 6 hours prior to spirometry, 
this information will be recorded by the study site staff using the equipment provided by the 
central spirometry vendor.  Additionally, if rescue medication is taken within 6 hours prior to 
spirometry at any of the scheduled visits, the visit should be rescheduled to the next possible 
day.
Daily use of rescue medication (the number of puffs taken in the previous 12 hours) will be 
recorded (once in the morning and once in the evening) by the patient using 
/ eDiary.
Unless clinically indicated, the type of rescue medication (i.e., SABA) a patient uses, the 
device used to deliver the medication (e.g. dry powder or HFA) and the way it is administered 
(e.g. with a spacer device) should not be adjusted. Any changes relating to the above must be 
recorded on the Concomitant medications CRF after the start of study drug.
5.5.7
Background therapy
All patients will remain on the incoming SoC asthma therapy they were taking at the 
screening visit (Visit 1) throughout the study. No dosage adjustments of the patient’s 
incoming SoC therapy will be permitted during the study. Short bursts of rescue systemic 
corticosteroids are allowed for treatment of asthma exacerbations, as clinically indicated (see 
Section 6.4.1).  The duration of a burst of rescue systemic corticosteroids should be 
approximately 3 to 10 days, and be of the shortest time needed to allow symptom control.
5.5.8

The investigator should instruct the patient to notify the study site about any new medications 
he/she takes after the patient was enrolled into the study. All medications, procedures and 
significant non-drug therapies (including physical therapy and blood transfusions) 
administered after the patient was enrolled into the study must be recorded in the eCRF.
5.5.9
Prohibited Treatment
Use of the treatments displayed in Table 5-3 is NOT allowed after the start of study (i.e., after 
Visit 101). Each concomitant drug must be individually assessed against all exclusion criteria 
and the tables below to see if it is allowed. If in doubt, the investigator should contact the 
Novartis medical monitor or designee before randomizing a patient or allowing a new 
medication to be started. This table is not considered all-inclusive. Medications should be 
assessed for adherence to the indication and other inclusion/exclusion criteria.

Discontinuation of study treatment
Patients may voluntarily discontinue active study medication (refuse study treatment but 
continue with study participation) at any time. Patients who wish to discontinue active 
study medication will be asked to remain in the study and complete all study visits.  
Patients withdrawn from study treatment will receive SoC asthma therapy according to 
investigator judgement.

The investigator should discontinue study treatment for a given patient if, on balance, he/she 
believes that continuation of study treatment would be detrimental to the patient’s well-being.  
Study treatment must be discontinued under the following circumstances: 

Withdrawal of informed consent (and the investigator must prematurely withdraw the 
patient from the study);

Pregnancy;

Female subjects non-compliant with the chosen effective method of contraception during 
the study: The investigator must provide appropriate advice on the continued use of 
effective contraception for at least one week (at least 5 half-lives of QAW039) after study 
drug discontinuation and follow up with the subject as appropriate at least to the end of 
this period;

Any protocol deviation that results in a significant risk to the patient’s safety;

Liver laboratory test abnormality / event (see Appendix 2):

Abnormal liver laboratory results requiring discontinuation – refer to Table 14-2;

If the investigator considers it appropriate after the confirmation of a liver safety 
monitoring signal:

ALT or AST ≥5xULN, or

ALT or AST ≥2.5xULN and total bilirubin  ≥1.5xULN (Appendix 2);

Premature unblinding of study treatment for a patient for any reason;

Total white blood cell count <1000 cells/µL;

If patients on statin therapy complain of persistent muscle pain without any obvious cause 
for greater than 3 days accompanied by increase in CK levels >10xULN or persistent 
intolerable muscle pain regardless of the accompanying CK level;

If a patient develops a medical condition that requires consistent use of prohibited 
treatment as per Section 5.5.9 or if patient exhibits a behavior of non-compliance 
regarding prohibited medication.
The appropriate personnel from the site and Novartis will assess whether investigational 
treatment should be discontinued for any patient whose treatment code has been broken 
inadvertently for any reason. 
Patients who discontinue investigational treatment should NOT be considered withdrawn 
from the study. If premature discontinuation of investigational treatment occurs for any reason 
the patient should continue attending the remaining study visits while off investigational 
treatment. The patient should return to the clinic as soon as possible for an investigational 
treatment discontinuation visit (TD). At this visit, the assessments listed under 
UNSCHEDULED-TD in Table 6-1 should be completed and recorded in the eCRF. The 
investigator and study staff must discuss with the patient, the patient’s continued participation 
in the study and request patients to continue attending study visits according to the study visit 
schedule with all assessments (except study drug related assessments such as compliance 
checks) completed up to Visit 299. If the patient cannot or is unwilling to attend any further 
visit(s), the site staff should maintain regular phone contact with the patient, or with a pe rson 
pre-designated by the patient. This phone contact should preferably be done according to the 
study visit schedule. Data will continue to be collected concerning the patients’ condition and 
changes in concomitant medications, surgeries and procedures, serious and non-serious 

Novartis

adverse events, and asthma exacerbations should be recorded in the appropriate eCRF if 
applicable. If necessary an unscheduled clinical visit may be arranged.
The investigator must also contact the IRT to register the patient’s discontinuation from 
investigational treatment
5.5.11
Discontinuation from study
Patients will only be discontinued from the study if they withdraw consent, die during 
the study or are lost to follow-up (see Section 5.5.13).
5.5.12
Withdrawal of consent
Patients may voluntarily withdraw consent to participate in the study for any reason at any 
time. 
Withdrawal of consent occurs only when a patient does not want to participate in the study 
anymore and does not want any further visits or assessments and does not want any further 
study related contacts and does not allow analysis of already obtained biologic material.
If a patient withdraws consent, the investigator must make every effort (e.g. telephone, e-mail, 
letter) to determine the primary reason for this decision and record this information. 
Investigational treatment must be discontinued and no further assessments conducted. All 
biological material that has not been analyzed at the time of withdrawal must not be used. 
Further attempts to contact the patient are not allowed unless safety findings require 
communicating or follow-up.
The investigator must also contact the IRT to register the patient’s withdrawal from the study.
Patients who prematurely discontinue study treatment or withdraw from the study will not be 
replaced.
5.5.13
Lost to follow-up 
For patients whose status is unclear because they fail to appear for study visits without stating 
an intention to withdraw, the investigator should show "due diligence" by contacting the 
patient, family or family physician as agreed in the informed consent and by documenting in 
the source documents steps taken to contact the patient, e.g. dates of telephone calls, 
registered letters, etc. A patient should not be considered lost to follow-up until his/her 
scheduled end of study visit would have occurred.
5.5.14
Emergency breaking of assigned treatment code 
Emergency treatment code breaks should only be undertaken when it is essential to treat the 
patient safely and efficaciously. Most often, study drug discontinuation and knowledge of the 
possible treatment assignments are sufficient to treat a study patient who presents with an 
emergency condition. Emergency treatment code breaks are performed using the IRT. When 
the investigator contacts the system to break a treatment code for a patient, he/she must 
provide the requested patient identifying information and confirm the necessity to break the 
treatment code for the patient. The investigator will then receive details of the investigational 
drug treatment for the specified patient and a fax or email confirming this information. The 
system will automatically inform Novartis that the code has been broken.

Novartis
Confidential
Page 47
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
It is the investigator’s responsibility to ensure that there is a dependable, redundant procedure 
in place to allow access to the IRT code break card at any time in case of emergency. The 
investigator will provide the protocol number, investigational treatment name if available, 
patient number as well as oral and written information to the patient on how to contact his/her 
backup in cases of emergency when he/she is unavailable to ensure that un-blinding can be 
performed at any time in the case of emergency. Study drug must be discontinued after 
emergency unblinding. Study drug must also be discontinued for any patient whose treatment 
code has been inadvertently broken or for any other non-emergency reason.
5.5.15
Study completion and post-study treatment 
Study completion for a patient will occur after he/she has completed 52 weeks of treatment 
(through to Visit 299) or they have prematurely withdrawn. Completion of the study will be 
when all randomized patients have completed 52 weeks of treatment and the post-treatment 
follow-up visit.
Patients who have been screened when enrolment target has been met will be allowed to 
proceed onto study participation.
A Safety Study of QAW039 is planned. At sites participating in the Safety Study, patients 
who successfully complete 52 weeks of treatment in this study (Study A2307) may be offered 
participation in the Safety Study; patient participation in the Safety Study will be optional. 
Patients not entering the safety study will complete the follow-up epoch and will not be given 
further access to study drug because the risk/benefit ratio will not yet have been substantiated 
and there are already other marketed therapeutic alternatives available to treat these patients. 
At the time of study completion or early termination, all patients will be placed on the 
appropriate asthma treatment as prescribed by the investigator.
The investigator must provide appropriate advice on the continued use of effective 
contraception for at least one week (at least 5 half-lives of QAW039) after the study 
completion (V299) or premature study drug discontinuation and follow up with the subject as 
appropriate at least to the end of this period.
The investigator must provide follow-up medical care for all patients who are prematurely 
withdrawn from the study, or must refer them for appropriate ongoing care. 
5.5.16
Early study termination 
The study can be terminated at any time for any reason by Novartis. Should this be necessary, 
the patient should be seen as soon as possible and treated for a prematurely withdrawn patient. 
The investigator may be informed of additional procedures to be followed in order to ensure 
that adequate consideration is given to the protection of the patient’s interests. The 
investigator will be responsible for informing the Institutional Review Board/Independent 
Ethics Committee (IRBs/IECs) of the early termination of the trial.

Visit schedule and assessments
Visits must be scheduled to allow randomized study drug to be taken in the morning 
Table 6-1 lists all of the assessments and indicates with an “x” when the visits are performed. 

Novartis
Confidential
Page 48
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
Patients should be seen for all visits as close as possible to the visit date. In case a treatment 
visit cannot occur as scheduled in the protocol, visits should be scheduled according to the 
specified visit window in the schedule of assessments. 
Patients, who discontinue study treatment before completing the study and will accept to 
remain in the study, will return for study visits as described in Section 5.5.10. If they fail to 
return for these assessments for unknown reasons, every effort should be made to contact 
them as specified in Section 5.5.10.  At the very least, patients should be asked if they can be 
contacted by phone by study personnel at the date they would have been scheduled to end the 
follow up epoch (4 weeks after premature drug discontinuation) to ask about concomitant 
medication use, surgery and procedures, SAEs, AEs and asthma exacerbations.
Patients will be required to attend the clinic in the morning at approximately the same 
time, so that pre-dose FEV1 assessments can be performed between 6:00 A.M. and 10:00
A.M. (+/- 1 hour). 
 
 At certain clinic visits, measurements will be collected 
2 hours post dosing; these measurements should be accounted for when scheduling clinic 
visits.
When the following assessments are scheduled to be performed at the same time-point, 
the order of priority will be as follows: 
1) Question on medication withholding for spirometry; 
2) Patient Reported Outcome instruments to be completed in the following order: 
ACQ-5, AQLQ+12,
at certain clinic visits; 
3) Vital signs;
4) ECGs;
5) Samples for urine/hematology/blood chemistry (At Visit 1 collect samples prior to 
spirometry. At all other visits, collect samples prior to the 1st pre-dose spirometry 
[which is the -45 min pre-dose spirometry] or between the 1st and 2nd pre-dose 
spirometry measurements.);
6) Samples for RAST/ImmunoCAP test, Total IgE, at certain clinic visit(s) (At Visit 
1 collect samples prior to spirometry. At all other visits, collect samples prior to the 1st
pre-dose spirometry [which is the -45 min pre-dose spirometry] or between the 1st and 
2nd pre-dose spirometry measurements.);
9) Spirometry assessments should be timed so that the Visit 1 spirometry assessment 
and all pre-dose spirometry assessments (i.e., FEV1 measurements) during the 
run-in epoch and treatment epoch are performed between 6:00 A.M. and 10:00
A.M. (+/- 1 hour). Other tests should be performed as close as possible to those 
spirometry times. During the run-in epoch and treatment epoch, two pre-dose 
spirometry assessments should be performed as follows:

Novartis


First pre-dose spirometry assessment: approximately 45 minutes prior to the 
dosing of study drug at the clinic visit.

Second pre-dose spirometry assessment: approximately 15 minutes prior to the 
dosing of study drug at the clinic visit.
10) Reversibility at certain visits (spirometry after administration of SABA) may be 
performed after 10:00 A.M. (+/- 1 hour);
11) In-clinic witnessed dosing of study drug;
12) ECGs (2 hour post-dose) at certain clinic visits;

1Scheduled clinic visits (starting at Visit101 and thereafter) are to occur in the morning at approximately the same time, so that the -45 min and -15 min pre-dose FEV1 assessments can be performed between 06:00 
A.M. and 10:00 A.M. (+/- 1 hour).
2Scheduled telephone calls (TCs) will be conducted to check the patients’ condition (Changes in concomitant medications, surgeries and procedures, serious and non-serious adverse events, and asthma exacerbations 
should be recorded in the appropriate eCRF if applicable). If necessary an unscheduled clinical visit may be arranged.
3For patients experiencing an asthma exacerbation during the run-in epoch, the run-in may be extended up to 6 weeks.
4The follow-up epoch applies to all patients except those patients who enter the safety study directly after Visit 299.

Information to be collected on screening failures and run-in 
failures
All patients who have signed informed consent but not entered into the next epoch (run-in)
will have the study completion page for the screening epoch, demographics, 
inclusion/exclusion, blood eosinophil counts, and serious adverse event (SAE) data collected. 
Adverse events that are not SAEs will be followed by the investigator and collected only in 
the source data.
All patients who have signed informed consent and have received single-blind study 
medication, but discontinue prior to randomization (run-in failures) should have all data for 
the visits they attended, the summary pages (Adverse Event, Concomitant Medication, 
Dosage Administrative Record), and screening and run-in disposition pages completed. All 
adverse events occurring after informed consent is signed should be recorded on the 
Adverse Event CRF. 
Investigators will have the discretion to record abnormal test findings on the medical history 
CRF whenever in their judgment, the test abnormality occurred prior to the informed consent 
signature.

Treatment exposure and compliance 
Study drug compliance will be assessed by the investigator and/or center personnel at 
designated visits by recording tablet counts from the previously dispensed bottles. 
The total number of doses of study drug administered since the last dispensing visit will be 
recorded in the Dosage Administration Record eCRF.
All doses of study drug taken at the clinic visits should be from the newly assigned 
medication packs, except at Visit 299 when the medication returned by the patient should 
be used.

Efficacy
6.4.1
Asthma exacerbations
The following definitions of exacerbations are used in this study.

A severe asthma exacerbation is defined as 

treatment with ‘rescue’ systemic corticosteroids for greater than or equal to 3 days 
and hospitalization; or

treatment with ‘rescue’ systemic corticosteroids for greater than or equal to 3 days 
and emergency department visit (greater than 24 hours*); or

death due to asthma. 

A moderate asthma exacerbation is defined as treatment with ‘rescue’ systemic 
corticosteroids for greater than or equal to 3 days either as an outpatient or in emergency 
department visits (Emergency department visit less than or equal to 24 hours).
*An emergency room visit greater than 24 hours is considered to be a hospitalization
‘Rescue’ systemic corticosteroids are tablets, suspension, or injection, or an increase of a 
patient’s maintenance systemic corticosteroids of greater than 2 fold (i.e., greater than 
doubling the maintenance dose of systemic corticosteroids). A single depo-injectable dose of 
corticosteroid will be considered the equivalent to a 3-day course of systemic steroids (Reddel, 
et al 2009). Endotracheal intubations will be captured on the CRF.
Scheduled spirometry should not be performed during an exacerbation until it has completely 
resolved.
If patients experience an asthma attack/exacerbation requiring systemic corticosteroids, 
hospitalization, or emergency room visit during the screening epoch, they may be re-screened 
once with the re-screening of the patient occurring 6 weeks or more after recovery from the 
asthma exacerbation. 
6.4.2
Asthma Control Questionnaire (ACQ-5)
In this study, the ACQ-5 will be used to assess improvements in asthma symptom control. 
The ACQ-5 will be collected in an electronic format.
The original ACQ consists of 7 items: 5 items on symptom assessment, 1 item on rescue 
bronchodilator use, and 1 item on airway caliber (% FEV1 predicted). The rescue 
bronchodilator use and % FEV1 predicted items are not included in the ACQ-5.  The ACQ 
was originally validated in patients with asthma over aged 17 years (Juniper 1999, 2006), and 

Novartis
Confidential
Page 61
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
is one of several asthma control measures recommended by the GINA Guidelines.  The ACQ 
has been fully validated, including patients aged from 6 to 16 years (Juniper 2010) and 
including a minimal important difference (MID) or smallest change that can be considered 
clinically important (0.5).
The ACQ-5 (see Appendix 8) will be self-administered at the clinic and only takes a few 
minutes to complete. Patients will be asked to recall how their asthma has been during the 
previous week and to respond to the symptom questions on a 7-point scale (0=no impairment, 
6=maximum impairment). The questions are equally weighted and the ACQ-5 score is the 
mean of the 5 questions: therefore, between 0 (totally controlled) and 6 (severely uncontrolled) 
(Juniper, et al 1999; Juniper, et al 2005; Juniper, et al 2006).
The ACQ will be completed by patients at the visits specified in the table of assessments (See
Table 6-1). The questionnaire should be completed before the AQLQ+12 and before any other 
assessments (see Section 6). The appropriate language version(s) of the questionnaire will be 
used in each participating country. The same language version of the questionnaire should be 
used by a particular patient throughout the study.   
The study coordinator should be familiar with the instrument and the associated user guides 
and training materials provided.  Patients should complete the questionnaire in a quiet area 
and are allowed to ask questions; however the site staff should take care not to influence the 
patient’s response. In response to a question, patients should be instructed to provide the truest 
or best response for them. 
Missing data should be avoided; therefore, the study coordinator will check the questionnaire 
for completeness before the patient leaves the clinic, and if necessary, encourage the patient to 
complete any missing responses. At later visits patients are not allowed to review their 
previous responses.
Completed questionnaires will be reviewed by the investigator for responses which may 
indicate potential AEs or SAEs.  The investigator should review not only the responses to the 
questions in the questionnaire but also for any unsolicited comments written by the patient.  If 
AEs or SAEs are confirmed then the physician must record the events as per instructions 
given in Section 7.1 and Section 7.2 of the protocol. Investigators should not encourage the 
patients to change the responses reported in the completed questionnaires.
6.4.3
Asthma Quality of Life Questionnaire for 12 years and older 
(AQLQ+12)
In this study, the disease-specific AQLQ+12 will be used to measure health-related quality of 
life in patients. The measure was originally validated for use in patients with asthma aged “12 
to 80 years (Juniper, et al 2005)”. The AQLQ+12 will be collected in an electronic format.
The AQLQ+12 comprises a total of 32 individual questions that span a total of four domains: 
symptoms, activity limitation, emotional function, and environmental stimuli. Test-retest 
reliability, construct validity (cross-sectional and longitudinal), and responsiveness have been 
demonstrated (See Appendix 9).
The AQLQ+12 will be self-administered at the clinic. It takes about 4 to 5 minutes to 
complete.  Patients are asked to recall their experiences during the previous 2 weeks and to 

Novartis
Confidential
Page 62
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
score each item on a 7-point scale (7 = not at all impaired to 1 = severely impaired). The  
AQLQ+12 yields individual domain scores, which is the mean of all items in each domain, 
and an overall score, which is the mean of all 32 individual responses. Higher scores indicate 
less impairment in HRQOL.
The questionnaire will be completed by patients at the visits specified in the table of 
assessments (See Table 6-1).
The appropriate language version(s) of the questionnaire will be used in each participating 
country. The same language version of the questionnaire should be used by a particular 
patient throughout the study.  
The study coordinator should be familiar with the instrument and the associated user guides 
and training materials provided. The patient should complete the questionnaire in a quiet area 
and be allowed to ask questions; however site staff should take care not to influence the 
patient’s responses. The patient will be instructed to provide the truest and for them best 
response. 
Missing data should be avoided, therefore, the study coordinator will check the questionnaire 
for completeness before the patient leaves the clinic, and if necessary, encourage the patient to 
complete any missing responses. At later visits patients are not allowed to review their 
previous responses. 
Completed questionnaires will be reviewed by the investigator for responses which may 
indicate potential AEs or SAEs.  The investigator should review not only the responses to the 
questions in the questionnaire but also for any unsolicited comments written by the patient.  If 
AEs or SAEs are confirmed then the physician must record the events as per instructions 
given in Section 7.1 and Section 7.2 of the protocol. Investigators should not encourage the 
patients to change the responses reported in the completed questionnaires.
The PROs ACQ, AQLQ+12, 
 questionnaires should always be completed before 
any other assessments and in the above order (see Section 6).

 will be used to 
alert the patient and/or investigator to possible signs of worsening asthma 
A central laboratory will be used to analyze and report blood chemistry/hematology/urinalysis 
and urine chemistries. A central ECG vendor will be used to collect, assess and report ECGs.
A Data Monitoring Committee will be set up to overview safety. See Section 8.3 for details.
6.5.1
Physical examination 
A complete physical examination will be performed at Visits 1 and 299
(and 
UNSECHEDULED-TD if a patient discontinues investigational treatment but continues with 
study participation).  It will include the examination of general appearance, skin, neck 
(including thyroid), eyes, ears, nose, throat, lungs, heart, abdomen, back, lymph nodes, 
extremities, vascular and neurological. If indicated based on medical history and/or symptoms, 
rectal, external genitalia, breast, and pelvic exams will be performed.
Abbreviated physical examinations will be performed at visits 101 to 207 (except Visit 201, 
since Visit 199 and 201 should occur on the same day). It will include the examination of the 
lungs and heart.
Information for all physical examinations must be included in the source documentation at the 
study site. Significant findings that are present prior to informed consent being granted must 
be included in the Relevant Medical History/Current Medical Conditions screen on the 
patient’s eCRF. Significant findings made after informed consent is given which meet the 
definition of an Adverse Event must be recorded on the Adverse Event screen of the patient’s 
eCRF.
6.5.2
Vital signs 
Vital signs will be assessed at every visit (except Visit 201, since Visit 199 and 201 should 
occur on the same day). Measurements will include blood pressure, pulse rate, and body 
temperature. 
After the patient has been sitting for ten minutes, with back supported and both feet placed on 
the floor, systolic and diastolic blood pressure will be measured three times using an 

Novartis
Confidential

Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
automated validated device, e.g. OMRON, with an appropriately sized cuff. The repeat sitting 
measurements will be made at 1 to 2 minute intervals and the mean of the three measurements 
will be used. In case the cuff sizes available are not large enough for the patient's arm 
circumference, a sphygmomanometer with an appropriately sized cuff may be used.
The patient’s condition must be monitored to rule out any clinically relevant arrhythmia or 
tachycardia.
Clinically notable vital signs are defined in Appendix 1.
6.5.3
Height and weight 
Height in centimeters (cm) will be measured at the visits specified in the table of assessments 
(See Table 6-1).
Body weight (to the nearest 0.1 kilogram [kg] in indoor clothing, but without shoes) will be 
measured at the visits specified in the table of assessments (See Table 6-1).
Body Mass Index (BMI) will be calculated as the weight in kg divided by the height in meters 
squared. 
6.5.4
Laboratory evaluations 
A central laboratory will be used for analysis of all specimens detailed in this section. Details 
on the collections, shipment of samples and reporting of results by the central laboratory are 
provided to investigators in the laboratory manual.
Details on clinically notable laboratory findings are defined in Appendix 1.
6.5.4.1
Hematology
Hemoglobin, hematocrit, red blood cell count, white blood cell count with differential, and 
platelet count will be measured according to the assessment schedule in Table 6-1. Other 
reflex testing will be performed as outlined in the laboratory manual.
6.5.4.2
Clinical chemistry
BUN/urea, creatinine, creatine kinase, total bilirubin, AST, ALT, alkaline phosphatase, 
gamma-glutamyl transpeptidase, lactate dehydrogenase, sodium, potassium, chloride, calcium, 
magnesium, iron, bicarbonate, cholesterol, triglycerides, high-sensitivity C-reactive protein, 
phosphorus, total protein, albumin, glucose, uric acid, amylase, lipase, CK-MB and Troponin-
I (in response to CK results outside of the normal range), HbA1c (collected at Visit 1 only)
and immunoglobulins (IgE, RAST/ImmunoCAP test), will be measured according to the 
assessment schedule in Table 6-1. Other reflex testing will be performed as outlined in the 
laboratory manual.
If the total bilirubin concentration is increased above 1.5 times the upper limit of normal range,
the total bilirubin will differentiated into the direct and indirect reacting bilirubin. 
All patients with laboratory tests containing clinically significant abnormalities should be 
followed until the values return to within the normal ranges or until a clinical explanation is 
identified, even after study medication has discontinued.

6.5.4.3
Urinalysis
Urine for urinalysis and urine chemistry will be collected according to the collection schedule 
in Table 6-1.  All samples for urinalysis and urine chemistry will be sent to the central 
laboratory for analysis.  The urinalysis evaluation by the central laboratory will include a 
urine dipstick for specific gravity, protein, glucose, leukocytes and blood and, if required, a 
microscopic examination. Urine chemistry and microscopic examination of the urine will be 
performed by the central laboratory as delineated in Table 7-1 “Specific Renal Alert Criteria 
and Actions” in Section 7.4 “Renal Safety Monitoring” of this protocol”. Other reflex testing 
will be performed as outlined in the laboratory manual.
6.5.5
Electrocardiogram (ECG) 
ECGs will be measured according to the assessment schedule in Table 6-1. At Visits 1 and 
101 an ECG will be measured to test for eligibility for trial inclusion.
ECGs must be recorded after 10 minutes of rest in the supine position to ensure a stable 
baseline. The preferred sequence of cardiovascular data collection during study visits is PRO 
collection first, followed by ECG, and then other study procedures (see Section 6). The 
Fridericia QT correction formula (QTcF) should be used for clinical decisions.
Triplicate 12 lead ECGs are to be collected with ECG machines supplied by the core 
laboratory.  Full details of all procedures relating to the ECG collection and reporting will be 
contained in an investigator manual to be provided to each investigator site.
The original trace will be sent electronically for central review directly from the ECG 
machine. Two ‘identical’ duplicate print-outs will be generated and kept at the investigator 
site as source documentation and as back-up for submission to the central laboratory in case 
of problems with the electronic transmission.  Each page of the ECG tracing should be labeled 
with study number (CQAW039A2307), subject initials (where this is allowed according to 
local regulations), subject number, date and time, and filed in the study site source documents.
For any ECGs with subject safety concerns, two additional ECGs should be performed to 
confirm the safety finding and copies forwarded to the central ECG laboratory for assessment. 
The final ECG assessments will be those provided by the central cardiologist ECG 
overreaders of the central vendor. Clinically significant ECG findings prior to dosing with 
investigational treatment must be discussed with the Novartis responsible person or designee.
Clinically significant abnormalities should be recorded on the relevant section of the medical 
history/Current medical conditions/AE CRF /eCRF page as appropriate.
In the event that the central cardiologist reports that an ECG is abnormal, then the investigator 
must comment as to whether the ECG abnormality is either clinically significant or clinically 
insignificant. If necessary a cardiologist may be consulted.
6.5.6
Pregnancy and assessments of fertility 
All women of child bearing potential will have a serum pregnancy test at Visits 1 and a urine 
pregnancy test at all other site visits (except visit 201, since Visit 199 and 201 should occur on 
the same day). 
Pregnancy testing will begin at the visit a patient is first identified as being of child bearing 
potential.

Novartis
Confidential
Page 69
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
In countries where monthly pregnancy testing is required for women of child-bearing 
potential by local laws or regulations, these patients will perform home urine pregnancy 
testing on the day of all telephone visits. These female patients will report the results of their 
home urine pregnancy test as “positive” or “negative” to study site staff as part of the 
telephone visit and the results will be recorded in source documents.
A positive urine pregnancy test requires immediate interruption of study medication until 
serum β-hCG is performed and found to be negative. If positive, the patient must be 
discontinued from the study treatment.

Airways hyper-reactivity test
An airways hyper-reactivity (AHR) test should be performed at Visit 101 if reversibility is not 
demonstrated at screening (Visit 1) and documented evidence for one of the other criteria for a 
clinical diagnosis of asthma is not met (see Section 4.1). A positive result is defined as a 
provoked fall in FEV1 of 20% (PC20) by methacholine  at ≤8 mg/ml (or histamine ≤10 mg/ml 
or acetylcholine <20 mg/mL) when not on ICS or ≤16 mg/ml or histamine ≤20 mg/ml or 
acetylcholine <40 mg/mL) on ICS therapy performed according to ATS/ERS guidelines.

Safety monitoring
7.1
Adverse events
An adverse event (AE) is any untoward medical occurrence (i.e., any unfavorable and 
unintended sign [including abnormal laboratory findings], symptom or disease) in a subject or 
clinical investigation subject after providing written informed consent for participation in the 

Novartis
Confidential
Page 71
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
study. Therefore, an AE may or may not be temporally or causally associated with the use of a 
medicinal (investigational) product.
The occurrence of adverse events should be sought by non-directive questioning of the patient 
at each visit during the study. Adverse events also may be detected when they are volunteered 
by the patient during or between visits or through physical examination, laboratory test, or 
other assessments.
Abnormal laboratory values or test results constitute adverse events only if they fulfill at least 
one of the following criteria:

they induce clinical signs or symptoms

they are considered clinically significant

they require therapy
Clinically significant abnormal laboratory values or test results should be identified through a 
review of values outside of normal ranges/clinically notable ranges, significant changes from 
baseline or the previous visit, or values which are considered to be non-typical in patient with
underlying disease. Investigators have the responsibility for managing the safety of individual 
patient and identifying adverse events. Alert ranges for labs and other test abnormalities are 
included in Appendix 1.
Adverse events should be recorded in the Adverse Events CRF under the signs, symptoms or 
diagnosis associated with them accompanied by the following information:

the severity grade: 

mild: usually transient in nature and generally not interfering with normal activities

moderate: sufficiently discomforting to interfere with normal activities

severe: prevents normal activities

its relationship to the study treatment:

Yes

No

its duration (start and end dates) or if the event is ongoing an outcome of not 
recovered/not resolved should be reported.

whether it constitutes a serious adverse event (SAE - See Section 7.2 for definition of 
SAE) and which seriousness criteria have been met.

action taken regarding study treatment
All adverse events should be treated appropriately. Treatment may include one or more of the 
following: 

no action taken (i.e. further observation only) 

study treatment dosage increased/reduced

study treatment interrupted/withdrawn

concomitant medication or non-drug therapy given 

non-drug therapy given 

patient hospitalized/patient’s hospitalization prolonged 

Novartis

Page 72
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307

its outcome (not recovered/not resolved; recovered/resolved; recovering/resolving, 
recovered/resolved with sequelae; fatal; or unknown)
Once an adverse event is detected, it should be followed until its resolution or until it is 
judged to be permanent, and assessment should be made at each visit (or more frequently, if 
necessary) of any changes in severity, the suspected relationship to the study drug, the 
interventions required to treat it, and the outcome.
Information about common side effects already known about the investigational drug can be 
found in the Investigator Brochure (IB) or will be communicated between IB updates in the 
form of Investigator Notifications. This information will be included in the patient informed 
consent and should be discussed with the patient during the study as needed.
The investigator should also instruct each patient to report any new adverse event (beyond the 
protocol observation period) that the patient, or the patient’s personal physician, believes 
might reasonably be related to study treatment. This information should be recorded in the 
investigator’s source documents, however, if the AE meets the criteria of an SAE, it must be 
reported to Novartis.
Adverse events of special interest are being evaluated in this study population. Definitions of 
IDRs are provided in Appendix 3.
7.2
Serious adverse events
7.2.1
Definition of SAE
An SAE is defined as any adverse event (appearance of (or worsening of any pre-existing) 
undesirable sign(s), symptom(s) or medical conditions(s) which meets any one of the 
following criteria:

is fatal or life-threatening 

results in persistent or significant disability/incapacity

constitutes a congenital anomaly/birth defect

requires inpatient hospitalization or prolongation of existing hospitalization, unless 
hospitalization is for:

routine treatment or monitoring of the studied indication, not associated with any 
deterioration in condition under study

elective or pre-planned treatment for a pre-existing condition that is unrelated to the 
indication under study and has not worsened since signing the informed consent

treatment on an emergency outpatient basis for an event not fulfilling any of the 
definitions of a SAE given above and not resulting in hospital admission 

social reasons and respite care in the absence of any deterioration in the patient’s 
general condition

is medically significant, i.e. defined as an event that jeopardizes the patient or may require 
medical or surgical intervention.
All malignant neoplasms will be assessed as serious under “medically significant” if other 
seriousness criteria are not met.

Novartis
Confidential
Page 73
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
Life-threatening in the context of a SAE refers to a reaction in which the patient was at risk of 
death at the time of the reaction; it does not refer to a reaction that hypothetically might have 
caused death if more severe (see Annex IV, ICH-E2D Guideline).
Medical and scientific judgment should be exercised in deciding whether other situations 
should be considered serious reactions, such as important medical events that might not be 
immediately life threatening or result in death or hospitalization but might jeopardize the 
patient or might require intervention to prevent one of the other outcomes listed above. 
Examples of such events are intensive treatment in an emergency room or at home for allergic 
bronchospasm, blood dyscrasias or convulsions that do not result in hospitalization or 
development of dependency or abuse (see Annex IV, ICH-E2D Guideline).
Any suspected transmission via a medicinal product of an infectious agent is also considered a 
serious adverse reaction.
All AEs (serious and non-serious) are captured on the CRF, SAEs also require individual 
reporting to DS&E as per Section 7.2.2.
7.2.2
SAE reporting
To ensure patient safety, every SAE, regardless of causality, occurring after the patient has 
provided informed consent and until 30 days after the last study visit must be reported to 
Novartis within 24 hours of learning of its occurrence. Any SAEs experienced after the 30 
days period should only be reported to Novartis if the investigator suspects a causal 
relationship to study treatment. 
Recurrent episodes, complications, or progression of the initial SAE must be reported as 
follow-up to the original episode, regardless of when the event occurs. This report must be 
submitted within 24 hours of the investigator receiving the follow-up information. An SAE 
that is considered completely unrelated to a previously reported one should be reported 
separately as a new event.
Information about all SAEs is collected and recorded on the Serious Adverse Event Report 
Form; all applicable sections of the form must be completed in order to provide a clinically 
thorough report. The investigator must assess the relationship of each SAE to each specific 
component of study treatment, (if study treatment consists of several components) complete 
the SAE Report Form in English, and submit the completed form within 24 hours to Novartis. 
Detailed instructions regarding the submission process and requirements for signature are to 
be found in the investigator folder provided to each site. 
Follow-up information is submitted as instructed in the investigator folder. Each re-
occurrence, complication, or progression of the original event must be reported as a follow-up 
to that event regardless of when it occurs.  The follow-up information should describe 
whether the event has resolved or continues, if and how it was treated, whether the blind was 
broken or not, and whether the patient continued or withdrew from study participation.
If the SAE is not previously documented in the Investigator’s Brochure or Package Insert 
(new occurrence) and is thought to be related to the investigational treatment a Drug Safety 
and Epidemiology Department associate may urgently require further information from the 
investigator for Health Authority reporting. Novartis may need to issue an Investigator 
Notification (IN) to inform all investigators involved in any study with the same 

Novartis

investigational treatment that this SAE has been reported. Suspected Unexpected Serious 
Adverse Reactions (SUSARs) will be collected and reported to the competent authorities and 
relevant ethics committees in accordance with EU Guidance 2011/C 172/01 or as per national 
regulatory requirements in participating countries.
7.3
Liver safety monitoring
To ensure patient safety and enhance reliability in determining the hepatotoxic potential of an 
investigational drug, a standardized process for identification, monitoring and evaluation of 
liver events has to be followed. 
The following two categories of abnormalities / adverse events have to be considered during 
the course of the study:

Liver laboratory triggers, which will require repeated assessments of the abnormal 
laboratory parameter

Liver events, which will require close observation, follow-up monitoring and completion 
of the standard base liver CRF pages
Please refer to Table 14-1 in Appendix 2 for complete definitions of liver laboratory triggers 
and liver events. 
Every liver laboratory trigger or liver event as defined in Table 14-1 of Appendix 2 should be 
followed up by the investigator or designated personal at the trial site as summarized below. 
Detailed information is outlined in Table 14-2 in Appendix 2.
For the liver laboratory trigger:

Repeating the LFT within the next week to confirm elevation.
These LFT repeats should be performed using the central laboratory if possible. If this is not 
possible, then the repeats can be performed at a local laboratory to monitor the safety of the 
patient. Repeats laboratory should then be performed at central laboratory as soon as possible. 
If a liver event is subsequently reported, any local LFTs previously conducted that are 
associated with this event should be reported on the Liver CRF pages.

If the elevation is confirmed, close observation of the patient will be initiated, including 
consideration of treatment interruption if deemed appropriate.
For the liver events:

Repeating the LFT to confirm elevation as appropriate

Discontinuation of the investigational drug if appropriate

Hospitalization of the patient if appropriate

A causality assessment of the liver event via exclusion of alternative causes (e.g., disease, 
co-medications)

An investigation of the liver event which needs to be followed until resolution. 
These investigations can include serology tests, imaging and pathology assessments, 
hepatologist’s consultancy, based on investigator’s discretion. All follow-up information, and 
the procedures performed should be recorded on appropriate CRF pages, including the liver 
event overview CRF pages.

Renal safety monitoring 
To ensure patient safety and enhance reliability in determining the nephrotoxic potential of an 
investigational drug, a standardized process for identification, monitoring and evaluation of 
renal events has to be followed. 
The following two categories of abnormal renal laboratory values have to be considered 
during the course of the study:
1. Serum event:

confirmed (after ≥ 24h) increase in serum creatinine of ≥ 25% compared to baseline 
during normal hydration status
2. Urine event:

urinary albumin-creatinine ratio (ACR) ≥1 g/g or ≥100 mg/mmol

urinary protein-creatinine ratio (PCR ) ≥1 g/g or ≥100 mg/mmol
Every renal laboratory trigger or renal event as defined in Table 7-1 should be followed up by 
the investigator or designated personnel at the trial site as summarized below. 
Table 7-1
Specific Renal Alert Criteria and Actions
Serum Event
Serum creatinine increase
25 – 49% compared to baseline
Confirm 25% increase after 24-48h 
Follow up within 2-5 days
Acute Kidney Injury: Serum creatinine 
increase  50 % compared to baseline
Follow up within 24-48h if possible
Consider drug interruption 
Consider patient hospitalization /specialized treatment
Urine Event
Albumin-creatinine ratio (ACR) ≥1g/g or 
≥100 mg/mmol;
Protein-creatinine ratio (PCR )≥1g/g or 
≥100 mg/mmol

Perform urine microscopy
Consider drug interruption / discontinuation 
For all renal events:
1. Document contributing factors in the CRF: co-medication, other co-morbid conditions, and 
additional diagnostic procedures performed 
2.
Monitor patient regularly (frequency at investigator’s discretion) until either: 

Event resolution: sCr within 10% of baseline or protein-creatinine ratio within 50% of 
baseline, or

Event stabilization: sCr level with ±10% variability over last 6 months or protein-
creatinine ratio stabilization at a new level with ±50% variability over last 6 months.

Idiosyncratic drug reactions monitoring
IDRs are adverse drug reactions that do not occur in most patients (i.e., they are rare, 
occurring 1 in 10,000 to 1 in 100,000 patients) and do not result from known pharmacological 
effects of a drug. Their onset is unpredictable and they may involve one or more organ 
systems, most notably the immune system, liver and blood cells.  
The investigator should pay special attention to any adverse events which may be a potential 
IDR reported by a patient. If such an event occurs, the investigator should report the event as 
per standard adverse event reporting procedures (i.e., serious adverse events for those meeting 
serious criteria and non-serious adverse events for those meeting non-serious adverse event
criteria as defined in the protocol). 
The investigator may be also be contacted by Novartis regarding AEs that may resemble an 
IDR. A list of terms considered IDRs are provided in Appendix 3 
Events with potential to be IDRs will be identified thorough a prespecified search algorithm 
based on the Standardised MedDRA Queries as described in the study analysis plan. These 
events will be reviewed by the DMC on a regular basis.
7.6
Pregnancy reporting
To ensure patient safety, each pregnancy occurring while the patient is on study treatment 
must be reported to Novartis within 24 hours of learning of its occurrence. The pregnancy 
should be followed up to determine outcome, including spontaneous or voluntary termination, 
details of the birth, and the presence or absence of any birth defects, congenital abnormalities, 
or maternal and/or newborn complications.
Pregnancy should be recorded on the Pharmacovigilance Pregnancy Form and reported by the 
investigator to the local Novartis Drug Safety and Epidemiology Department. Pregnancy 
follow-up should be recorded on the same form and should include an assessment of the 
possible relationship to the investigational treatment.
Any SAE experienced during the pregnancy and unrelated to the pregnancy must be reported 
on a SAE form.

Data review and database management
8.1
Site monitoring 
Before study initiation, at a site initiation visit or at an investigator’s meeting, a Novartis 
representative will review the protocol and CRFs with the investigators and their staff. During 
the study, Novartis employs several methods of ensuring protocol and GCP compliance and 
the quality/integrity of the sites’ data. The field monitor will visit the site to check the 
completeness of patient records, the accuracy of entries on the (e)CRFs, the adherence to the 
protocol and to Good Clinical Practice, the progress of enrollment, and to ensure that study 
treatment is being stored, dispensed, and accounted for according to specifications. Key study 
personnel must be available to assist the field monitor during these visits.  Continuous remote 
monitoring of each site’s data may be performed by a centralized Novartis CRA organization.   
Additionally, a central analytics organization may analyze data & identify risks & trends for 

Novartis

Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
site operational parameters, and provide reports to Novartis Clinical Teams to assist with trial 
oversight.
The investigator must maintain source documents for each patient in the study, consisting of 
case and visit notes (hospital or clinic medical records) containing demographic and medical 
information, laboratory data, electrocardiograms, and the results of any other tests or 
assessments. All information on CRFs must be traceable to these source documents in the 
patient's file. The investigator must also keep the original informed consent form signed by 
the patient (a signed copy is given to the patient).
The investigator must give the monitor access to all relevant source documents to confirm 
their consistency with the CRF entries. Novartis monitoring standards require full verification 
for the presence of informed consent, adherence to the inclusion/exclusion criteria, 
documentation of SAEs, and of data that will be used for all primary variables. Additional 
checks of the consistency of the source data with the CRFs are performed according to the 
study-specific monitoring plan. No information in source documents about the identity of the 
patients will be disclosed.
8.2
Database management and quality control 
Novartis staff, or a CRO working on behalf of Novartis, review the data entered into the CRFs 
by investigational staff for completeness and accuracy and instruct the site personnel to make 
any required corrections or additions. Queries are sent to the investigational site using an 
electronic data query. Designated investigator site staff is required to respond to the query and 
confirm or correct the data. If the electronic query system is not used, a paper Data Query 
Form will be faxed to the site. Site personnel will complete and sign the faxed copy and fax it 
back to Novartis staff that will make the correction to the database. The signed copy of the 
Data Query Form is kept at the investigator site.
Concomitant medications entered into the database will be coded using the WHO Drug 
Reference List, which employs the Anatomical Therapeutic Chemical classification system. 
Concomitant procedures, non-drug therapies and adverse events will be coded using the 
Medical dictionary for regulatory activities (MedDRA) terminology.
Laboratory samples will be processed centrally and the results will be sent electronically to 
Novartis (or a designated CRO).
ECG readings will be processed centrally and the results will be sent electronically to 
Novartis (or a designated CRO).
Centralized spirometry readings will be processed centrally and the results will be sent 
electronically to Novartis (or a designated CRO).
Diary data will be entered into an electronic diary by the patient. The system will be supplied 
by a vendor(s), who will also manage the database. The database will be sent electronically to 
Novartis (or a designated CRO).
Randomization codes and data about all study drug(s) dispensed to the patient and all dosage 
changes will be tracked using an Interactive Response Technology (IRT). The system will be 
supplied by a vendor, who will also manage the database. The database will be sent 
electronically to Novartis (or a designated CRO).

Each occurrence of a code break via IRT will be reported to the clinical team and monitor.  
The code break functionality will remain available until study shut down or upon request of 
Novartis. 
The occurrence of relevant protocol deviations will be determined. After these actions have 
been completed and the database has been declared to be complete and accurate, it will be 
locked and the treatment codes will be unblinded and made available for data analysis. Any 
changes to the database after that time can only be made after written agreement by Novartis 
Development management.
8.3
Data Monitoring Committee 
An independent, external data monitoring committee (DMC) will be set up to review safety 
data (including specific safety summaries for adolescent participants) from this trial and other 
Phase III trials in the QAW039 asthma development program, as well as to conduct the 
planned single interim analysis for futility as described in Section 3.5 and Section 9.6. The 
DMC will consist of a group of experts independent of the sponsor, analyses for the DMC 
will be prepared by individuals independent of the sponsor and sponsor personnel will remain 
fully blinded to the interim results until the final clinical database lock as described in Section 
5.4. Based on the safety implications of the data, the DMC may recommend modification or 
termination of the study. There will be no stopping for demonstrated efficacy prior to the 
completion of the study at either the unblinded safety reviews or the futility interim analysis, 
because a sufficiently large safety dataset is needed in addition to efficacy data.  Therefore, no 
statistical adjustment will be made to the final analysis. Full details on procedures, the DMC 
and futility criteria will be specified in a DMC charter.
A charter for the Data Monitoring Committee (DMC) will be developed in a separate 
document. The DMC is the autonomous data and safety advisory group for Novartis. Novartis 
will be described as the “Sponsor” in the charter, though the Sponsor of the trial in any 
particular country may in fact be an affiliate of this entity. 
The purpose of the DMC charter is to define: 
1. the membership of the DMC 
2. responsibilities of the DMC and Novartis 
3. responsibilities of independent biostatistician and programmer 
4. the relationship of the DMC with other trial components and data flow 
5. the purpose and timing of DMC meetings 
6. procedures for ensuring proper confidentiality, addressing conflict of interest, and 
ensuring proper communication 
The charter will comply with Novartis standard operating procedures and is in accordance 
with the FDA guidance (FDA 2006) and CHMP guidelines (CHMP 2006) on DMCs. If 
significant safety issues arise in between scheduled meetings, ad-hoc meetings will be 
scheduled to review the data.

Data collection 
Designated investigator staff will enter the data required by the protocol into the OC/RDC 
system. Designated investigator site staff will not be given access to the system until they 
have been trained. 
Automatic validation procedures within the system check for data discrepancies during and 
after data entry and, by generating appropriate error messages, allow the data to be confirmed 
or corrected online by the designated investigator site staff. The Investigator must certify that 
the data entered into the electronic Case Report Forms are complete and accurate. After 
database lock, the investigator will receive copies of the patient data for archiving at the 
investigational site.

Data analysis 
9.1
Analysis sets 
The screened set (SCR) will include all patients who provided informed consent.
The Randomized Set (RAN) will include all patients that were randomized. Data from these 
patients will be analyzed according to the treatment to which the patient was assigned at 
randomization.
The full analysis set (FAS) will include all randomized patients who received at least one dose 
of study drug. It was considered reasonable to limit the FAS to patients who took trial 
medication, because the decision on whether or not treatment is started will not be influenced 
by the treatment group assignment due to the effective treatment blinding procedures 
described in Section 5.4. Following the intent-to-treat principle, patients will be analyzed 
according to the treatment they were assigned to at randomization.
The per-protocol set (PPS) will include all patients in the FAS without any major protocol 
deviations such as violation of major entry criteria. Patients may also be considered censored 
for the PPS analysis at the time of major post-baseline protocol deviations. Major protocol 
deviations will be defined in the data handling plan prior to database lock and the un-blinding 
of the study. Patients will be analyzed according to the treatment they received.
The safety set (SAF) will include all patients who received at least one dose of study drug. 
Patients will be analyzed according to the treatment they received.
 
The analysis of the primary objective will be performed on the FAS. The PPS will be used for 
the supportive analysis of the primary and the key secondary variables. The FAS will be used 
for the analysis of all other efficacy variables. The SAF will be used in the analysis of all 
safety variables.

Note that the set of patients included in the FAS and SAF are the same except that the SAF 
allows the inclusion of non-randomized patients who receive study drug in error.
9.2
Patient demographics and other baseline characteristics 
Patient demographics and baseline characteristics measured before randomization including 
age (calculated from date of birth to date of Visit 1), sex, race, ethnicity, height, weight, body 
mass index (BMI), relevant medical history,  including smoking history, asthma duration, use 
of long-acting beta-agonists, use of oral corticosteroids, pre-
 FEV1, 
percent predicted FEV1, ACQ score, blood eosinophil count, number of exacerbations in the 
previous year 
will be summarized by treatment group for the FAS. Categorizations 
of age will include at least the categories of <18, 18 to <65, 65-74, 75-84 and ≥85 years of age.
Blood eosinophil counts will also be summarized for the SCR.
9.3
Treatments 
The duration of exposure, the number of patients randomized who completed the foreseen 
course of study medication and the number of patients who discontinued from the study 
medication will be summarized.
Medications started and stopped prior to study drug, taken concomitantly, and started 
following last study drug dose (if applicable) will be summarized by treatment group in 
separate tables in the SAF. Concomitant therapies will be recorded, listed and summarized 
separately for asthma related medications / non-drug therapies and other medications.  
Concomitant asthma related medications will be summarized by pre-defined category.  
Concomitant medications not related to asthma will be summarized by pharmacological (ATC)
class and preferred term.  More than one ATC class per medication is possible and the 
medication will be reported under all applicable classes.
Short acting β2-agonist usage (number of puffs) during the screening epoch will be 
summarized. 
Usage of asthma medication (e.g. LABA, ICS) at baseline will be summarized. Usage of oral 
corticosteroids (OCS) including dose will also be summarized. Patients taking prohibited 
concomitant medications will be noted in the summary of protocol deviations.
Compliance with study medication over the entire study will be summarized as the percentage 
of days with study medication intake during the period from first intake to last intake.
9.4
Analysis of the primary variable(s)
The primary analysis for this study will be conducted according the intention to treat principle.
9.4.1
Variable(s)
The primary variable for this study is the number of moderate-to-severe asthma exacerbations 
as defined in Section 6.4.1 experienced by each patient per patient year of follow-up. The start 
date of a moderate-to-severe asthma exacerbation recorded in the CRF is defined as the first 
day of ‘rescue’ systemic corticosteroid use, or the date of death if no rescue corticosteroids 
were taken prior to an asthma related death. Further asthma exacerbations will only be 
considered additional events, if the start date of the next episode is at least 7 days after the end 

Novartis
Confidential
Page 81
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
of the previous exacerbation episode. The end of an exacerbation is defined as the last day of 
systemic corticosteroid use.
The key secondary variables are AQLQ+12, ACQ-5 and pre-dose FEV1 at the end of the 52 
week treatment period. Their definition and analysis is described in Section 9.5.
9.4.2
Statistical model, hypothesis, and method of analysis
Primary null hypotheses
The trial will be considered positive, if one or more of the two QAW039 doses demonstrate a 
statistically significant reduction in the rate of moderate-to-severe asthma exacerbations. As 
described below, the two doses will be tested in parallel and each dose may achieve 
statistically significant results irrespective of the results achieved by the other dose. 
The primary null hypotheses are:

H0 450 eosinophil subgroup: relative risk ratio for the QAW039 450 mg QD group versus placebo 
in patients with eosinophil count ≥ 250 cells/µl = 1, 

H0 150 eosinophil subgroup: relative risk ratio for the QAW039 150 mg QD versus placebo in 
patients with eosinophil count ≥ 250 cells/µl = 1,

H0 450 overall: relative risk ratio for the QAW039 450 mg QD versus placebo in the overall 
study population = 1 and

H0 150 overall: relative risk ratio for the QAW039 150 mg QD versus placebo in the overall 
study population = 1.
The primary alternate hypotheses are:

HA 450 eosinophil subgroup: relative risk ratio for the QAW039 450 mg QD group versus placebo 
in patients with eosinophil count ≥ 250 cells/µl ≠1,

HA 150 eosinophil subgroup: relative risk ratio for the QAW039 150 mg QD group versus placebo 
in patients with eosinophil count ≥ 250 cells/µl ≠1,

HA 450 overall: relative risk ratio for the QAW039 450 mg QD group versus placebo in the 
overall study population ≠1 and

HA 150 overall: relative risk ratio for the QAW039 150 mg QD group versus placebo in the 
overall study population ≠1.
The superiority of QAW039 over placebo will be considered confirmed if at least one of the 
four primary null hypotheses is rejected in favor of the respective two-sided alternative 
hypotheses.
Familywise type I error rate control
The familywise type I error rate will be controlled at the two-sided 5% level across the 
primary and key secondary null hypotheses using the closed testing procedure specified by 
Figure 9-1 using the graphical method of  Bretz, et al 2009. In this closed testing procedure 
the primary null hypothesis about exacerbations in the subset of patients with eosinophil count 
≥ 250 cells/µl for each dose acts as a gatekeeper for the other null hypotheses for the same 
dose.

Closed testing procedure for primary and key secondary objectives
Vertices with associated weights denote the individual null hypotheses and their local significance 
levels (initially α is split 50%:50% across the primary null hypotheses regarding the subgroup with 
blood eosinophils ≥ 250 cells/μl for the 2 QAW039 doses). Directed edges between the vertices 
specify how the local significance levels are propagated in case of significant results. Dotted Dashed 
edges with a weight of ε indicate that the local significance level from the key secondary null 
hypotheses of a dose will only be propagated to the other population for the same dose, once all key 
secondary null hypotheses for a dose and population have been rejected. Dotted edges with a weight 
of ε2 (much smaller than ε) indicate that the local significance level from the key secondary null 
hypotheses of a dose will only be propagated to the other dose, once all key secondary null 
hypotheses for a dose have been rejected.
Initially, 50% of the alpha is assigned to each of the primary null hypotheses regarding the 
subgroup with blood eosinophils ≥ 250 cells/μl for the QAW039 450 mg QD and QAW039 
150 mg QD doses, respectively. 
Once this first primary null hypothesis for a dose has been rejected, the alpha will be 
distributed to the other primary null hypothesis regarding the overall population for the same 
dose and the key secondary null hypotheses regarding the subgroup with blood eosinophils ≥ 
250 cells/μl for that same dose. If the null hypothesis regarding the primary endpoint for the 
overall population is rejected for a dose, then alpha is reassigned to the key secondary null 
hypotheses regarding the overall population for that dose. Alpha will only be reassigned from 
the set of null hypotheses for a dose to the null hypotheses for the other dose once all null 
hypotheses for the dose to which the alpha was originally assigned have been rejected. 
Once the primary null hypothesis for a dose and population has been rejected, all key 
secondary null hypothesis for that dose and population are tested and can be rejected 
irrespective of whether the other key secondary null hypotheses for that dose and population 
can be rejected. However, FEV1 will be initially given the highest local significance level due 
to its regulatory importance.

Statistical model for primary variable
These hypothesis tests, as well as point estimates and confidence intervals will be based on a 
negative binomial regression model  with the natural logarithm of the duration of follow-up in 
years as an offset variable (Keene, et al 2007; Keene, et al 2008), treatment group, 
randomization stratum (use or non-use of oral corticosteroids as part of SoC asthma therapy, 
patient age at Visit 1 [<18 years or ≥18 years], and when analyzing the overall population,
peripheral blood eosinophil counts at Visit 1 [<250 cells/l or ≥250 cells/l]) and region as a 
fixed class effects, the natural logarithm of the number of asthma exacerbations (requiring 
treatment with oral or systemic corticosteroids) in the 12 months prior to screening and the 
baseline pre-dose FEV1 as a continuous linear covariate. Note that the duration of follow-up 
will be the planned duration of follow-up for all patients, because any missing data will be 
imputed as described in Section 9.4.3. The inclusion of the offset is nevertheless useful to 
make regression coefficients easier to interpret. Should despite the inclusion criteria a patient 
with no exacerbations requiring treatment with oral or systemic corticosteroids in the 12 
months prior to screening be included in the trial, such a patient will be considered to have 
had 0.5 such exacerbations.
A negative binomial model will be used, because patient heterogeneity beyond that captured 
by the available patient-level covariates is expected. This can lead to over dispersed 
cumulative counts and zero inflation. A negative binomial model can better capture such 
heterogeneity than a Poisson model and can be seen as a Poisson model with the intensity 
distributed across patients according to a Gamma distribution (Keene, et al 2007).
Summary statistics for the primary variable
The primary variable will be summarized by treatment group in terms of the mean rate (events 
per patient year of follow-up) overall and for different time intervals, the distribution of 
patients by number of exacerbations and using plots of Nelson's (1995) nonparametric 
estimate of the mean cumulative function. The components of the composite primary endpoint 
will be summarized.
9.4.3
Handling of missing values/censoring/discontinuations
Despite all attempt to ensure complete follow-up for all patients, some patients may not be 
followed for exacerbations for the whole planned study duration. Missing data will be 
imputed using a multiple imputation approach similar to the “missing at random and jump to 
reference” approach described by Keene et al. (2014). 
The first step in implementing this approach is fitting a Bayesian negative multinomial model 
with non-informative priors to the data. This model will distinguish on- and off-treatment data 
for the QAW039 group and assume that the same event rate as in the placebo group applies 
after QAW039 discontinuation. The model will include the same covariates as the primary 
model, as well as a log length of follow-up offset variable. Missing data on exacerbations in 
both treatment groups will then be imputed by simulation using independent pseudorandom 
draws from the posterior for the parameters of this model in the conditional distribution of the 
missing data given the observed data as described by Keene et al. (2014). The imputation will 
use a mixture of the jump to reference and the missing at random approaches (Keene et al. 
2014) and will distinguish the following two cases:

Novartis
Confidential
Page 84
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
1. No further treatment effect versus placebo will be imputed for QAW039 patients that 
discontinue treatment and are lost to follow-up due to (or following a treatment 
discontinuation due to) lack of efficacy, adverse events or death. 
2. A continued treatment effect for QAW039 patients being lost to follow-up for reasons 
likely to be unrelated to study treatment (e.g. lost to follow-up, withdrew consent) will be 
assumed.
A large number of imputed datasets will be created, with their number chosen based on 
computational feasibility, but at least 1,000 based on the recommendation of Keene et al. 
(2014). Each dataset will be analyzed using the model described in Section 9.4.2 and the 
results will be combined on the log-scale using Rubin’s rule (Barnard and Rubin 1999). 
Regression coefficients and their confidence intervals will then be exponentiated to obtain 
rates and risk ratios.
9.4.4
Supportive analyses
The primary and the key secondary analyses will be repeated for the PPS.
The analysis results and the imputed data for different methods for imputing missing data will 
be compared.
If feasible retrieved data after the discontinuation of treatment (retrieved drop-out) will be 
used to impute missing post-treatment discontinuation data as a sensitivity analysis. While 
retrieved drop-outs may be a particularly suitable basis for imputing data for non-retrieved 
drop-outs, this analysis may not be feasible or may require simplification of the imputation 
model, because observed post-treatment discontinuation data may be sparse.
An on-treatment analysis will also be conducted. In this analysis all moderate-to-severe 
asthma exacerbations as defined in Section 6.4.1 will be counted, if the start date of the 
exacerbation is on or after the first day of treatment with double-blind study medication, but 
before or on the day after the last day of treatment with double-blind study medication. In this 
analysis a negative binomial regression model with the natural logarithm of the duration of 
on-treatment follow-up in years as an offset variable will be used. The duration of on-
treatment follow-up in years will be calculated for each patient as (treatment end date -
treatment start date + 1 day)/365.25 without taking into account treatment interruptions. Such 
a negative binomial model assumes that missing data after censoring either due to losses to 
follow-up or the end of treatment are missing at random conditional on the baseline covariates 
and the preceding data on events per follow-up time included in the analysis (Cook and 
Lawless 2007). Under this assumption the model implicitly imputes the missing data and the 
data censored at the end of treatment assuming a hypothetical situation of continued treatment 
with an unchanged on-treatment event rate for the patient (Committee for Medicinal Products 
for Human Use 2010). This analysis and missing data handling approach is in-line with the 
recently completed MENSA exacerbation trial for the monoclonal anti-interleukin-5 antibody 
mepolizumab in a similar population (Ortega, et al 2014). It is therefore the most appropriate 
analysis for a comparison of the results of the present trial to the MENSA trial.
In a tipping point analysis it will be explored by how much the event rate post-discontinuation 
would have had to increase (or continuous outcomes to worsen) in the primary and key 
secondary analyses in order to change the trial conclusions.

As a worst reasonable case analysis a disappearing treatment effect for all patients that are 
lost-to-follow-up will be used (jump-to-reference). This is a sensitivity analysis for the effect 
of assuming a continued treatment effect for patients withdrawing from the study for reasons 
considered to be likely unrelated to study therapy (see Section 9.4.3)
In a further rank-based sensitivity analysis for the primary endpoint withdrawal from the trial 
and death will be directly treated as negative trial outcomes for patients. Patients that 
completed the trial will be ranked as having had a more favorable outcome than patients that 
withdrew from the trial, who will in turn be ranked as having had a more favorable outcome 
than patients that died. Within each of these categories patients will be ranked according to 
(number of exacerbations + 0.5)/patient years of follow-up. Compared to solely ranking 
patients according to the number of exacerbations or solely according to the duration of 
follow-up, this ensures that patients lost to follow-up very early in the trial without 
experiencing any exacerbations will not be ranked more favorably than patients that nearly 
completed the trial and only had 1, or 2 exacerbations, while also ensuring that a patient with 
10 exacerbations that was lost to follow-up after 11 months and 1 day is not ranked as having 
a more favorable outcome than a patient with 0 exacerbations that was lost to follow-up after 
11 months. A Wilcoxon rank-sum test stratified by randomization stratum will be used to 
analyze the ranked data.
Supportive analyses will also explore whether allowing the possibility of declining or 
increasing exacerbation rates over time affects study conclusions.
Time to first asthma exacerbation and mean duration of asthma exacerbations will also be 
analyzed.
The absolute difference in the rates of moderate to severe asthma exacerbation rates per 
patient year and resulting number of patients that needs to be treated for 1 year to prevent one 
exacerbation will also be reported with confidence intervals.
For comparison to historical study results, data for the key secondary endpoints using last-
observation-carried-forward will also be provided.
Subgroups
The primary and key secondary analyses will also be conducted by subgroup including for 
key demographic (e.g. age, sex, race, BMI, geographic region) and disease related subgroups 
(e.g. number of exacerbations in the previous year, OCS use/GINA step, baseline FEV1 
tertiles, ACQ tertiles, as well as blood eosinophil counts).
Relationship of efficacy and baseline eosinophil levels
In addition to subgroup analyses with different baseline eosinophil levels, the functional 
relationship between the treatment effect and baseline blood eosinophil levels as a continuous 
covariate will be investigated for the primary and key secondary variables.

Analysis of secondary variables
9.5.1
Efficacy variables 
The key secondary variables of this trial are the mean of the two pre-dose FEV1 assessments 
at the week 52 visit, AQLQ+12 and ACQ-5 at the end of the 52 week treatment period. Data

from the preceding visits will be used primarily to describe the onset of action and for missing 
data imputation.
The key secondary variables of AQLQ+12, ACQ-5 and pre-dose FEV1 will be analyzed using 
an analysis of covariance (ANCOVA) model with factors for treatment group, randomization 
stratum and region, as well as the baseline AQLQ+12, baseline ACQ-5 and baseline  pre-
bronchodilator FEV1 as continuous linear covariates.
The null hypothesis will be tested for each dose group, each population (subgroup with 
peripheral blood eosinophil counts at Visit 1 ≥250 cells/l or overall population) and each key 
secondary variable using this model versus the two-sided alternative hypotheses
For each key secondary endpoint, each QAW039 dose and each population the null 
hypothesis is that the treatment difference compared to placebo at the week 52 visit = 0, while 
the alternative hypothesis is that the treatment difference to placebo at the week 52 visit ≠0.
This model will be fitted to each of multiple imputations generated using the jump-to-
reference approach described by Carpenter et al. (2013). In a similar manner to the primary 
analysis a continued treatment effect will be imputed for QAW039 patients with intermittent 
missing data and those QAW039 patients discontinuing double-blind study medication due to 
reasons likely to be unrelated to study medication (see Section 9.4.3). For all other QAW039 
patients with missing data and placebo patients with missing data imputation will be based on 
the placebo group. The average of the two FEV1 assessments will only be formed after 
multiple imputations so that if one of the two FEV1 assessments at a visit is missing, the 
average will be between the one available assessment and a second imputed assessment.
The test for the key secondary variables AQLQ+12, ACQ-5 and pre-dose FEV1 in patients 
with eosinophil count ≥ 250 cells/µl and for the overall population for each dose will be 
performed, if the primary null hypothesis has been rejected for the same dose for patients with 
eosinophil count ≥ 250 cells/µl and for the overall population, respectively. The local 
significance level for each secondary null hypothesis will be determined based on the closed 
testing procedure specified by Figure 9-1.
Sensitivity analyses for the key secondary endpoints
A range of sensitivity analyses for the key secondary endpoints similar to those described in 
Section 9.4.3 and Section 9.4.4 will be conducted. Further supportive analyses will look at the 
treatment effect separately for each visit. 
Additionally, a mixed model for repeated measures (MMRM) with an unstructured covariance 
structure will be fitted for secondary variables to evaluate the average treatment effect during 
weeks 12 to 52 of the trial. These MMRMs will include treatment group, visit, randomization 
stratum and region as fixed class effects, and the baseline AQLQ+12, baseline ACQ-5 and 
baseline pre-bronchodilator FEV1 as continuous linear covariates. Treatment group by week 4 
visit and baseline value by visit interactions will also be included in the model. This average 
effect will be both investigated using the main data imputation approach, as well as in an on-
treatment analysis. Note that the supportive on-treatment analysis for the on-treatment values 
(from start of double-blind study medication to the day after the last day of treatment) will use 
a MMRM with an unstructured covariance structure. This model implicitly imputes 
unrecorded values and the data censored at the end of treatment assuming a hypothetical 
situation of continued treatment with an unchanged on-treatment effect that is constant across

the week 12 to 52 visits for patients in a similar manner as the on-treatment analysis using a 
negative binomial model described in Section 9.4.4. 
An analysis of percent change from baseline in pre-dose FEV1 will also be performed. For 
this analysis pre-dose FEV1 and its baseline will be log-transformed for analysis and results 
will be back-transformed to obtain geometric means and ratios of geometric means to allow 
an interpretation as percent change from baseline. 
9.5.1.1
Asthma Quality of Life Questionnaire for 12 years and older 
(AQLQ+12)
The 32 items in the AQLQ+12 are divided into 4 domain-specific scores and a total score as 
follows: 

Symptoms = Mean of Items 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 29, 30 (12 items) 

Activity limitation  = Mean of Items 1, 2, 3, 4, 5, 11, 19, 25, 28, 31, 32 (11 items) 

Emotional function  = Mean of Items 7, 13, 15, 21, 27 (5 items) 

Environmental Stimuli = Mean of Items 9, 17, 23, 26 (4 items) 

Overall Score = Mean of Items 1 to 32 (32 items) 
Each item of the AQLQ+12 is equally weighted and scored along a 7-point scale, where 1 
indicates maximal impairment and 7 indicates no impairment. Thus, higher scores indicate 
better asthma-related HRQOL. There is a mean score calculated for each of the four domains, 
as well as an overall quality-of-life score, which is the mean score of all 32 items. The 
resultant overall scores will be between 1 and 7.
The developer suggests no more than 10% of missing data. This means no more than 3 
missing responses for the overall score and no more than 1 missing response per domain.  For 
the symptoms and activity domain scores, one missing value per domain is allowed.  For the 
emotional function and environmental stimuli domain scores, no missing values are allowed.
If these limits for missing questions are exceeded, the variable will be considered missing and 
will be imputed as described in Section 9.5.1.
The minimal important difference (MID), defined as “the smallest difference in score which 
patients perceive as beneficial and would mandate, in the absence of troublesome side effects 
and excessive cost, a change in the patient’s management,” of 0.5 has been established for this 
questionnaire as clinically significant (Juniper, et al 1994).
9.5.1.2
Pre-dose FEV1
The baseline measurement is defined as the mean of the pre-bronchodilator FEV1 values
taken at the last visit in the clinic prior to first dose of study drug. 
If the pre-dose FEV1 is taken within 6 hours of SABA use, or within 12 hours of twice-daily 
LABA (including fixed dose combinations of LABA and ICS) use, or 24 hours of once-daily 
LABA (including fixed dose combinations of LABA and ICS) use, or 24 hours of once-daily 
LAMA use, then the individual FEV1 value is set to missing. 
9.5.1.3
Asthma Control Questionnaire (ACQ-5)
The ACQ measures asthma symptom control and consists of 7 items. It includes the 5 most 
important symptoms, 1 about rescue bronchodilator use and 1 about airway calibre (FEV1 %

predicted pre-bronchodilator). Patients will be asked to recall their experiences during the past 
one week and to response items 1-6 (night-time waking, symptoms on waking, activity 
limitation, shortness of breath, wheeze, and rescue short-acting β2-agonist use) on a 7-point 
scale (0 – totally controlled, 6 – extremely poorly controlled). The ACQ-5 score calculated 
based on the 5 questions of the 5 most important symptoms. The5 questions of the ACQ-5 are 
equally weighted. The ACQ-5 score is the mean of the responses to the 5 questions. The 
resultant score will be between 0 and 6.
A score of 1.5 at baseline indicates patients who entered the study had inadequately controlled 
asthma (Juniper 2006). In addition, the minimal important difference (MID) or smallest 
change that can be considered clinically important is 0.5. 
9.5.2
Safety variables
All safety data will be summarized for the safety set.
Safety summaries will be primarily based on on-treatment data with selected tables also 
presented for the all data after the first intake of study drug, while all databased safety data 
will be listed. 
Unless otherwise specified, all safety summaries will be provided for patients with eosinophil 
count ≥ 250 cells/µl, for patients with eosinophil count < 250 cells/µl and for the overall study 
population.
Adverse events
Adverse events after informed consent including asthma exacerbations will be summarized 
and listed.
Adverse events starting on or after the time of the first intake of study drug and until the day 
after the last intake of study drug will be classified as a treatment emergent adverse events. 
Any adverse events that started during the study after informed consent before the time of the 
first intake of study drug will be classified as a prior adverse events and not included in 
tabulations of treatment emergent adverse events. 
The following treatment emergent adverse event summaries will be produced, overall by 
system organ class and preferred term, overall by system organ class, preferred term and 
maximum severity, suspected drug-related adverse events by system organ class and preferred 
term, serious adverse events by system organ class and preferred term, and adverse events 
leading to permanent discontinuation of study-drug by system organ class and preferred term.

discontinuation events will be produced for adverse events and serious adverse events by 
system organ class and preferred term.
The number and percentage of patients with treatment emergent adverse events of special 
interest (e.g. IDRs), as well as cardiac events  will be summarized for each type of event with 
a break-down for each type of event by SMQ (when applicable) and preferred term. Time-to-
first-event analyses using Kaplan-Meier plots and Cox regression with the same model terms 
as the primary efficacy analysis model will be reported for each type of event, as well as 
incidence for recurrent events per patient-year of follow-up. The strategy for identifying these 
events will be defined in the detailed statistical analysis plan for this trial.
Vital signs
On-treatment data from the vital signs (systolic blood pressure, diastolic blood pressure, and 
pulse rate) will be summarized by treatment and scheduled visit. The maximum and minimum 
on-treatment systolic blood pressure, diastolic blood pressure, and pulse rate post-baseline 
(including values from post-baseline unscheduled and premature discontinuation visits) can 
also be summarized by treatment. Absolute on-treatment body weight will be summarized by 
scheduled visit. The on-treatment change from baseline to each scheduled post-baseline visit 
will be summarized by vital sign parameter, scheduled visit and treatment with standard 
descriptive statistics.
Notable on-treatment values and notable on-treatment changes from baseline in vital signs 
will be summarized.
Electrocardiogram (ECG) 
The on-treatment changes from baseline will be summarized by ECG parameter, schedule 
visit where baseline and post baseline values are both available. 
The following quantitative on-treatment variables will be summarized by treatment at each 
scheduled post-baseline visit: ventricular rate, QT interval, RR interval, PR interval, QRS 
duration, heart rate, and Fridericia’s QTc. The maximum on-treatment QTc (including values 
from post-baseline unscheduled and premature discontinuation visits) will also be summarized. 
Notable on-treatment values and notable on-treatment changes from baseline in quantitative 
ECG variables will be summarized.
Laboratory data
All laboratory data will be listed with abnormal values flagged. The laboratory on-treatment 
values and the on-treatment change from baseline for continuous laboratory parameters will 
be summarized at each visit. A frequency table of results for categorical on-treatment 
laboratory parameters will be produced for the whole study duration. 
Shift tables relative to the normal reference ranges will be used to summarize the on-treatment 
change from baseline to post-baseline for each laboratory parameter. For each on-treatment 
laboratory parameter, the patients will be classified into one of the four mutually exclusive 
groups (low, normal, high, and low + high).
For selected laboratory parameters, the number and percentage of patients with newly 
occurring or worsening on-treatment laboratory abnormalities meeting the clinically notable

criteria will be summarized by laboratory parameter at any time-point over the treatment 
period, considering all post-baseline data from scheduled, unscheduled and premature 
discontinuation visits. Patients with any newly occurring or worsening on-treatment value 
meeting the clinically notable criteria will be counted under the applicable criteria. 
9.6
Interim analyses 
As described in Section 3.5, a single futility interim analysis will be conducted in addition to 
periodic unblinded safety reviews by the DMC (see Section 8.3) using data (including specific 
safety summaries for adolescent participants) from this trial and other Phase III trials in the 
QAW039 asthma development program. No stopping for demonstrated efficacy prior to the 
completion of the study is foreseen at either the unblinded safety reviews or the futility 
interim analysis, because a sufficiently large safety dataset is needed in addition to efficacy 
data and thus, no statistical adjustment will be made to the final analysis.
9.7
Sample size calculation
To be conservative a mean placebo event rate of 1.5 events per patient year of follow-up has 
been assumed for this study; this is a slightly lower rate than the 1.75 events per patient-year 
observed in the placebo group of the MENSA trial (Ortega, et al 2014) and the same event 
rate as assumed for the DREAM trial, although the actual DREAM placebo event rate was 2.4 
events per patient year of follow-up (Pavord, et al 2012). A 40% reduction in the rate of 
asthma exacerbations per year in the QAW039 treatment compared to placebo has been 
assumed for the subgroup with high eosinophils ≥ 250 cells/μl for this study; this is 
considered to be highly clinically relevant and at the same time realistic based on the DREAM 
and MENSA trials conducted in similar patient populations. In the DREAM trial 75 mg 
mepolizumab reduced the number of asthma exacerbations per patient per year by 48%, 

Novartis

Page 91
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
250mg mepolizumab by 39% and 750mg mepolizumab by 52% compared with placebo. In 
the MENSA trial intravenous mepolizumab reduced the number of asthma exacerbations per 
patient per year by 47% and subcutaneous mepolizumab by 53% compared with placebo. 
These relative risk reductions were taken into account, because the observed reduction in 
sputum eosinophils with QAW039 in Study CQAW039A2208 were similar to those observed 
with mepolizumab (Haldar, et al 2009; Pavord, et al 2012). On this basis it is postulated 
QAW039 may reduce the rate of asthma exacerbations to a similar extent as mepolizumab. 
For the subgroup with eosinophils < 250 cells/μl a lesser relative risk reduction of 30% was 
assumed. However, it should be noted that the trial may produce a significant result with a 
smaller reduction in exacerbations than that assumed for power calculations and that such a 
reduction could still be considered clinically relevant.
As reported in online supplementary material for the MENSA publication the negative 
binomial dispersion parameter for the exacerbation rates was estimated to be 0.8 in the 
DREAM trial. In the DREAM trial approximately 15% of patients in the mepolizumab arms 
and 20% of patients in the placebo arm were lost to follow-up by the end of the 1-year trial, 
while in the 32 week MENSA trial only 6 to 8% of patients were lost across groups. Therefore, 
a constant exponential hazard rate over time for treatment discontinuation is assumed with 
15% of patients off treatment by 1 year in the active treatment groups and the placebo group.
No further treatment effect versus placebo has been assumed during the off-treatment, i.e. a 
mean event rate of 1.5 events per patient year has been assumed for patients after treatment 
discontinuation in both the QAW039 and placebo groups.
A 1:1:1 randomization was used, even though the power to demonstrate the superiority of at 
least one arm versus placebo would likely have been higher with an increased assignment to 
the placebo group, in order to not reduce the amount of efficacy and safety information for 
each QAW039 dose group. 
Negative binomial counts were simulated based on the assumptions above and the testing 
procedure in Figure 9-1 was applied to each simulation result. For the purpose of evaluating 
the power for the primary trial objectives, it was assumed that none of the key secondary null 
hypotheses would be rejected.
For this study a two-sided significance level of 5% is used for testing. As shown in Table 9-1
188 patients per arm in the subpopulation with blood eosinophils ≥ 250 cells/μl and 282
patients per arm in the overall population corresponding to a total sample size of 846 patients 
provide greater than 80% power for demonstrating the superiority of each dose of QAW039 
compared to placebo in the subpopulation with blood eosinophils ≥ 250 cells/μl and overall 
population under the described assumptions.

Subpopulation means the subpopulation with blood eosinophils ≥ 250 cells/μl, while other 
population refers to the subpopulation with blood eosinophils < 250 cells/μl. Power results 
are based on 100,000 simulated trials per scenario. Only results for primary endpoints were 
simulated. For the purpose of evaluating the power for the primary trial objectives, it was 
assumed that none of the key secondary null hypotheses would be rejected. All simulations 
were performed in SAS 9.4.
If statistical significance is achieved in the primary test, the test for the key secondary 
variables pre-dose FEV1, AQLQ+12 and ACQ-5 will be performed. The local significance 
level for each secondary null hypothesis will be determined based on the closed testing 
procedure shown in Figure 9-1. For the power for each key secondary variable in the 
subpopulation with blood eosinophils ≥250 cells/μl and overall population, it was 
conservatively assumed that only the null hypothesis for the primary endpoint for the 
respective dose in the subpopulation and overall population would be rejected. For AQLQ+12 
and ACQ5 the power was additionally calculated conditional on both the null hypothesis for 
the primary endpoint and pre-dose FEV1 for the respective dose in the subpopulation and 
overall population having been rejected. The power for each key secondary endpoint is shown 
in Table 9-2. However, note that the power for the key secondary endpoints will be higher 
once the null hypotheses relating to other key secondary variables or other doses have been 
rejected. For the power calculation of secondary endpoints no further treatment effect versus 
placebo has been assumed for patients with treatment discontinuation.
It was assumed that QAW039 achieves a difference of 150 mL against placebo in FEV1 after 
52 weeks for patients that remain on treatment. A SD of 380 mL was assumed for the analysis 
in FEV1. Given a 15% treatment discontinuation rate by week 52, the planned sample size
will give 80% power for each dose in the subpopulation at the resulting local two-sided 
significance level of 1.625% and 90% power for each dose in the overall population at the
resulting local two-sided significance level of 0.698%.
Assuming a clinically important true improvement of at least 0.5 in AQLQ+12 after 52 weeks 
treatment for patients that remain on treatment, a standard deviation (SD) of 1 and 15% 
treatment discontinuation rate by week 52, the planned sample size per arm will provide 76% 
power for each dose in the subpopulation with blood eosinophils ≥ 250 cells/μl at the resulting 
local two sided significance level of 0.075% and 93% power for each dose in the overall

population at the resulting local two-sided significance level of 0.038% after the respective 
primary null hypothesis has been rejected. 
Assuming a difference of 0.5 against placebo in ACQ-5 after 52 weeks for patients without 
treatment discontinuation, a SD of 1.1, and a 15% treatment discontinuation rate by week 52, 
the planned sample size will give 59% power for each dose in the subpopulation at the
resulting local two-sided significance level of 0.05% and 78% power for each dose in the 
overall population at the resulting two-sided local significance level of 0.015% after the 
respective primary null hypothesis has been rejected.

Prior to study start, the investigator is required to sign a protocol signature page confirming 
his/her agreement to conduct the study in accordance with these documents and all of the 
instructions and procedures found in this protocol and to give access to all relevant data and 
records to Novartis monitors, auditors, Novartis Quality Assurance representatives, designated 
agents of Novartis, IRBs/IECs, and regulatory authorities as required. If an inspection of the 
clinical site is requested by a regulatory authority, the investigator must inform Novartis 
immediately that this request has been made.
10.4
Publication of study protocol and results 
Novartis assures that the key design elements of this protocol will be posted in a publicly 
accessible database such as clinicaltrials.gov. In addition, upon study completion and 
finalization of the study report the results of this trial will be either submitted for publication 
and/or posted in a publicly accessible database of clinical trial results.
10.5
Quality Control and Quality 
Novartis maintains a robust Quality Management (QM) system that includes all activities 
involved in quality assurance and quality control, including the assignment of roles and 
responsibilities, the reporting of results, and the documentation of actions and escalation of 
issues identified during the review of quality metrics, incidents, audits and inspections.

Audits of investigator sites, vendors, and Novartis systems are performed by Novartis Pharma 
Auditing and Compliance Quality Assurance (CQA), a group independent from those 
involved in conducting, monitoring or performing quality control of the clinical trial. The 
clinical audit process uses a knowledge/risk based approach.
Audits are conducted to assess GCP compliance with global and local regulatory requirements, 
protocols and internal SOPs, and are performed according to written Novartis processes.
11
Protocol adherence 
This protocol defines the study objectives, the study procedures and the data to be collected 
on study participants. Additional assessments required to ensure safety of patients should be 
administered as deemed necessary on a case by case basis. Under no circumstances should an 
investigator collect additional data or conduct any additional procedures for any research 
related purpose involving any investigational drugs.
Investigators ascertain they will apply due diligence to avoid protocol deviations. If an 
investigator feels a protocol deviation would improve the conduct of the study this must be 
considered a protocol amendment, and unless such an amendment is agreed upon by Novartis 
and approved by the IRB/IEC and health authorities, where required, it cannot be 
implemented. All significant protocol deviations will be recorded and reported in the CSR.
11.1
Protocol Amendments
Any change or addition to the protocol can only be made in a written protocol amendment that 
must be approved by Novartis, Health Authorities where required, and the IRB/IEC prior to 
implementation. Only amendments that are intended to eliminate an apparent immediate 
hazard to patients may be implemented immediately provided the Health Authorities are 
subsequently notified by protocol amendment and the reviewing IRB/IEC is notified. 
Notwithstanding the need for approval of formal protocol amendments, the investigator is 
expected to take any immediate action required for the safety of any patient included in this 
study, even if this action represents a deviation from the protocol. In such cases, the reporting 
requirements identified in Section 7 Safety Monitoring should be followed.

Appendix 1: Clinically notable laboratory values and vital 
signs
The central laboratory will flag laboratory values falling outside of the normal ranges on the 
central laboratory reports.  Investigators are responsible for reviewing these abnormal values 
for clinical significance, signing the laboratory reports to indicate their review, and reporting 
values considered clinically significant in the appropriate eCRF.
Any clinically significant abnormal laboratory value should be evaluated and followed-up by 
the investigator until normal or a cause for the abnormality is determined.
See Appendix 2 for specific liver event and laboratory test trigger definitions and follow-
up requirements.
For ECGs, a notable QTc value is defined as a QTcF (Fridericia) interval of ≥450 msec for 
males or ≥460 msec for females – all such ECGs will be flagged by the Central CRO and 
require assessment for clinical relevance and continuance of the patient by the Investigator.

Appendix 5: Spirometry Guidance
Equipment
Spirometers must meet the specifications and performance criteria recommended in the 
American Thoracic Society (ATS)/European Respiratory Society (ERS) Standardization of 
Spirometry1. Spirometers must have the capacity to print 
 tracings.  All spirometry values 
should be reported at BTPS by the method established by the manufacturer.
Calibration
The spirometer should be calibrated every morning before any spirometric measurements for 
the study are performed. Calibration reports should be printed and stored as source data at the 
site. 
Preparing the test subject
On study days when spirometry will be performed, patients should refrain from the following:

Coffee, tea, chocolate, cola and other caffeine-containing beverages and foods and ice-
cold beverages  for 4 hours prior to spirometry

Alcohol for 4 hours prior to spirometry

Strenuous activity for 12 hours prior to spirometry 

Exposure to environmental smoke, dust or areas with strong odors 
Every effort should be made to assure consistent testing conditions throughout the study.  A 
seated position with nose clips is recommended to reduce risks related to dizziness or syncope.  
When possible, spirometry should be conducted by the same technician using the same 
spirometer.  To minimize the effects of diurnal variation on lung function, spirometry visits 
should start at approximately the same time of day at each visit.  
Performing Spirometry
The subject’s age, height and gender will be entered into the spirometer.  It is important that 
the height is measured accurately at the study site. Spirometry, an effort-dependent test, 
requires careful instruction and cooperation of the subject.  The technician should ensure a 
good seal around the mouthpiece, and confirm that the subject’s posture is correct. The 
subject should be instructed to perform a maximal inspiration, followed by maximum forced 
expiration until no more air can be exhaled or for at least 6 seconds. Expiration must be rapid 
with exertion of maximal effort. The results of spirometry should meet the ATS/ERS criteria 
for acceptability and repeatability. Acceptability criteria should be applied before repeatability 
is determined.  
 
 

Novartis
Confidential
Page 106
Amended Protocol Version v03 – Clean
Protocol No. CQAW039A2307
Acceptability
An acceptable maneuver has the following characteristics: 

No hesitation or false start;

A rapid start;

No cough, especially during the first second of the maneuver;

No glottic closure or obstruction by tongue or dentures

No early termination of exhalation (minimum exhalation time of 6 seconds is 
recommended, or no volume change for at least 1 second) or the subject cannot continue 
to exhale further
Repeatability
The 2 largest 
 FEV1 values from 3 acceptable maneuvers should not vary by more 
than 0.150 L.
If patient does not meet the repeatability or acceptability criteria during the screening epoch, 
patient may be rescreened once or allow one spirometry retest.
Recording of data
The greatest FEV1
 from any of the acceptable curves are recorded. (The greatest 
FEV1
 may not necessarily result from the same acceptable curve).  
Predicted normal
For all subjects, this study will utilize the global lung function 2012 equations (GLI2012) 
published by Quanjer et al 20122 or Japanese Respiratory Society3.
Reversibility
All reversibility evaluations should follow the recommendations of the ATS/ERS Task force: 
Standardization of Lung Function Testing1. A pre-bronchodilator spirometry* assessment 
should be performed after withholding of specified medications as specified in Table 5-2
“Medications to be withheld prior to spirometry”.
Administer 400µg of salbutamol/albuterol (or equivalent) following the completion of the pre-
bronchodilator assessment*. 
 
Subjects will be considered reversible if an increase of at least 12% (and 200 ml) is
demonstrated after administration of the salbutamol/albuterol.
*NOTE: At visits with two pre-dose spirometry assessments (please see Table 6-1 for 
schedule of assessments) the FEV1 from the 2nd pre-dose spirometry assessment (performed 

Novartis
Confidential

approximately 15 min prior to in-clinic witnessed study drug administration) should be used
for FEV1 (pre-bronchodilator).
