Brief title 
Study of efficacy and safety of secukinumab 2 mL auto-injector 
(300 mg) in subjects with moderate to severe plaque psoriasis 
Sponsor and Clinical Phase 
Novartis/Phase IIIb 
Investigation type 
Drug 
Study type 
Interventional 
Purpose and rationale 
The primary purpose of this study is to assess efficacy, safety 
and tolerability of a 2 mL pre-filled auto-injector (AI) of 300 mg 
secukinumab. Results of this study will support the registration 
of secukinumab 300 mg 2 mL auto-injector. 
This 52-week, double-blind, randomized, parallel-group, and 
placebo-controlled study is using the recommended dose of 
300 mg secukinumab which has been approved in Japan, 
United States of America (USA) , European Union (EU), 
Switzerland and other countries for the treatment of moderate 
to severe psoriasis in adults 
Primary Objective(s) 
The primary objective is to demonstrate the efficacy of 
secukinumab 300 mg when administered in 2 mL auto-injector 
in subjects with plaque-type psoriasis with respect to both 
Psoriasis Area and Severity Index (PASI) 75 and Investigator’s 
Global Assessment modified 2011 (IGA mod 2011) 0 or 1 
response (co-primary endpoint) at Week 12, compared to 
placebo 
Secondary Objectives 
Key secondary objective 
To demonstrate the efficacy of secukinumab 300 mg when 
administered with a 2 mL auto-injector in subjects with plaque- 
type psoriasis with respect to PASI 90 at Week 12, compared 
to placebo. 
Other secondary objectives 
• To assess the efficacy of secukinumab 300 mg when 
administered with a 2 mL auto-injector in subjects with plaque- 
type psoriasis with respect to PASI score, IGA mod 2011 score, 
PASI 50 / 75 / 90 / 100 and IGA mod 2011 0 or 1 response up 
to Week 12 compared to placebo, and over time up to Week 52. 
• To investigate the clinical safety and tolerability of 
secukinumab 300 mg 2 mL auto-injectors as assessed by vital 
signs, clinical laboratory variables, and adverse events (AE) 
monitoring, compared to placebo. 
• To assess the subject usability (ability to follow instructions 
for use (IFU) and potential use-related hazards) and 
satisfaction with the new secukinumab 2 mL auto-injectors 
utilizing a self-administered Self-Injection Assessment 
Questionnaire (SIAQ) and investigator/site staff observation of 
secukinumab 300 mg 2 mL auto-injector administration.

• To investigate the effects of secukinumab 300 mg when 
administered with a 2 mL auto-injectors with respect to 
Dermatology Life Quality Index (DLQI) 0 or 1 achievement and 
DLQI changes at Week 12 compared to placebo, and over time 
up to Week 52. 
Study design 
This is a 52-week multicenter, randomized, double-blind, 
placebo-controlled, parallel-group trial in approximately 120 
subjects with moderate to severe plaque-type psoriasis. 
The study consists of 3 periods: Screening Period (of at least 1 
week and up to 4 weeks), Treatment Period 1 (12 weeks) and 
Treatment Period 2 (40 weeks). 
Subjects will be randomized using a 2:2:1:1 ratio to the following 
groups following a stratification by body weight (< 90 .kg or ≥ 90 
kg): secukinumab 300 mg regimen group (2 mL auto-injector), 
secukinumab 300 mg regimen group (2 x 1 mL pre-filled 
syringes (PFS)). Placebo – Secukinumab 300 mg (2 mL AI) or 
to Placebo – Secukinumab 300 mg (2 x 1mL PFS). The 
treatment of the 2 placebo groups will be the same during 
treatment Period 1 and will only differ after Week 12 in treatment 
period 2 for non-responders only. 
Prior to administration of the Week 12 dose, PASI 90 response 
will be evaluated and subjects classified accordingly. Based on 
the PASI 90 responders at the Week 12 visit, subjects on 
placebo will either remain on placebo during the Treatment 
Period 2 or be re-assigned to secukinumab 300 mg treatment 
(2 mL AI or 2 x 1mL PFS). 
Population 
Approximately 120 subjects with moderate to severe plaque 
psoriasis will be randomized in approximately 30 centers 
worldwide. Approximately 150 subjects are expected to be 
screened to provide the number of randomized subjects. 
Key Inclusion criteria 
1. Subjects must be able to understand and communicate with 
the investigator and comply with the requirements of the study 
and must give a written, signed and dated informed consent 
before any study related activity is performed. Where relevant, 
a legal representative will also sign the informed study consent 
according to local laws and regulations. 
2. Men or women of at least 18 years of age at the time of 
Screening. 
3. Chronic plaque-type psoriasis present for at least 6 months 
and diagnosed before Randomization. 
4. Moderate to severe psoriasis as defined at Randomization 
by: 
• PASI score of 12 or greater, and 
• IGA mod 2011 score of 3 or greater (based on a scale of 0 
– 4), and 
• Body Surface Area (BSA) affected by plaque-type psoriasis 
of 10% or greater. 
5. Candidate for systemic therapy. This is defined as a subject 
having moderate to severe chronic plaque-type psoriasis that 
is inadequately controlled by 
• Topical treatment and/or 

Novartis

detailed in the protocol have to be adhered to. Subjects not 
willing to limit Ultraviolet (UV) light exposure (eg, sunbathing 
and/or the use of tanning devices) during the course of the 
study will be considered not eligible for this study since UV 
light exposure is prohibited. 
Note: administration of live vaccines 6 weeks prior to 
Randomization or during the study period is also prohibited. 
4. Previous exposure to secukinumab (AIN457) or any other 
biologic drug directly targeting Interleukin (IL)-17 or the IL-17

150 mg 1 mL Pre-Filled Syringe (PFS) x 2, and placebo 
• Entire study: secukinumab 300 mg 2 mL AI, secukinumab 
150 mg 1 mL PFS x 2, placebo switched secukinumab 300 mg 
2 mL AI, placebo switched secukinumab 150 mg 1 mL PFS x 
2, any secukinumab 300 mg 2 mL AI, any secukinumab 150 
mg 1 mL PFS x 2, any secukinumab 300 mg and placebo 
The following hypotheses will be included in co-primary testing 
procedure: 
• H1: secukinumab 300 mg (2 mL AI) is not superior to 
placebo with respect to PASI 75 response at Week 12 
• H2: secukinumab 300 mg (2 mL AI) is not superior to 
placebo with respect to IGA mod 2011 0 or 1 response at 
Week 12 
Within each of hypotheses H1 and H2 is tested at α = 2.5% 
(one-sided). The testing sequence will continue to key 
secondary endpoint PASI 90 at α = 2.5% (one-sided) only if 
both H1 and H2 have been rejected at α (one-sided) such that 
a family-wise type-I-error of α (one-sided) is kept. 
• H3: secukinumab 300 mg (2mL AI) is not superior to 
placebo with respect to PASI 90 response at Week 12 
The primary analysis method will be the logistic regression with 
treatment group; baseline bodyweight strata and baseline PASI 
score as explanatory variables. Odds ratios will be computed 
for comparisons of secukinumab dose regimen versus placebo 
utilizing the logistic regression model fitted. In case the logistic 
regression does not converge, an exact logistic regression will 
be performed. In case of response rates of 0% or of 100% in 
one of the treatment groups, Fisher’s exact test will be applied. 
Confidence intervals for risk difference will be derived based 
on the exact method.

Introduction 
1.1 
Background 
Psoriasis is a chronic relapsing disease of the skin characterized by variable clinical features. 
The lesions are classified as erythemato-squamous, which indicates that both the vasculature 
(erythema) and the epidermis (increased scale formation) are involved (Christophers and 
Mrowietz 2003, Griffiths and Barker JNWN 2007). 
Plaque-type psoriasis (also called plaque or chronic plaque psoriasis) is the most frequent 
clinical presentation and therefore, also called psoriasis vulgaris. The erythematous plaques are 
well defined with sharp borders. The silvery grey scale on the surface of the lesions is easily 
removed. Sharply demarcated lesions can present on the extensor surfaces of the knees and 
elbows and on the trunk. Lesions are often symmetrically distributed. The size of the lesions is 
highly variable. In approximately one-third of patients, more than 10% of the body is covered, 
and this is termed moderate to severe psoriasis. Clinical disease can be assessed by a trained 
healthcare practitioner, using the Psoriasis Area and Severity Index (PASI) score. This tool 
ranks severity and area of erythema (redness), induration (thickness), and desquamation (scale) 
of the plaques in different body sections, with 72 as the maximal score. PASI score of at least 
12 is required to classify for moderate to severe psoriasis. 
Treatment of moderate to severe psoriasis is based on phototherapy, systemic treatment (eg, 
methotrexate, cyclosporine, acitretin, apremilast) and biologics. The introduction of tumor 
necrosis factor alpha (TNFα)-inhibitors such as etanercept, infliximab and adalimumab, 
increased treatment options for physicians. The primary indication for these biological products 
is the treatment of moderate to severe psoriasis not responding satisfactorily to conventional 
treatment such as phototherapy, methotrexate or acitretin. 
Extensive clinical experience with TNFα-inhibitors has been collected over the past 10 years 
and these agents are generally considered to be effective and relatively safe (Papp et al 2005). 
However, a substantial percentage of patients do not respond well to treatment with a TNFα- 
inhibitor. This inadequate response may imply either a primary unsatisfactory response (eg, not 
achieving a decrease in PASI score of at least 75% after adequate duration of treatment), an 
initially adequate response that is lost over time (secondary failure) or intolerance for the TNFα- 
inhibitor. The percentage of patients with an inadequate response to TNFα-inhibitors can be as 
high as 40%-60% (Van Lümig et al 2010). 
The arrival of the anti-Interleukin (IL) 12/23 class of biological drugs provided clinicians with 
another treatment option (Kerdel and Zaiac 2015). Ustekinumab has shown good clinical 
efficacy in a Phase III study (Papp et al 2008). PASI response rates were better than those of 
etanercept, and efficacy was generally maintained up to 3 years after initiation of treatment 
(Kimball et al 2012). 
More recently, a number of IL-17A and IL-17RA inhibitors have been investigated in Phase III 
studies for the treatment of a range of immune mediated inflammatory diseases (Puig 2014) 
amongst which ixekizumab and brodalumab have been approved in 2017 in USA for moderate 
to severe psoriasis patients. 
Secukinumab (AIN457) is a recombinant high-affinity fully human monoclonal anti-human IL- 
17A antibody of the immunoglobulin (Ig) G1/κ-class. Secukinumab binds to human IL-17A 

Novartis 
Clinical Trial Protocol (Version 00)

and neutralizes the bioactivity of this cytokine. IL-17A is the central cytokine of a newly defined 
subset of inflammatory T cells, the T helper 17 cells which, in several animal models, are pivotal 
in multiple autoimmune and inflammatory processes. IL-17A is produced by memory effector 
CD4+ and CD8+ T lymphocytes, but also largely by innate immune cells (including neutrophils, 
mast cells, γδ-T cells, ILC3 cells, NK and iNKT cells), and is being recognized as one of the 
principal pro inflammatory cytokines in immune mediated inflammatory diseases. Its 
neutralization is expected to treat the underlying pathophysiology of immune mediated disease, 
and as a consequence provide relief of (psoriatic) symptoms. Secukinumab has been shown to 
be superior to etanercept (Langley et al 2014) and superior to ustekinumab (Thaci et al 2015) 
in clearing skin of subject with moderate to severe psoriasis with a comparable safety profile. 
Secukinumab has a different mode of action to TNFα-inhibitors and IL-12/23 inhibitors as it 
targets a different interleukin (i.e., IL-17A). Secukinumab (Cosentyx®) with a recommended 
dose of 300 mg was approved in 2014 in Japan, and 2015 in USA, EU, Switzerland, and in 
many other countries for the treatment of moderate to severe psoriasis in adults. Secukinumab 
is available as a powder for solution for injection, and as a solution of 150 mg in 1 mL for 
injection using pre-filled syringe or a pen/auto-injector (AI). Currently two injections (each 
with 150 mg) for the recommended dose (300 mg) are required. In order to allow patients to 
receive only one injection for the delivery of secukinumab 300 mg instead of two injections of 
150 mg, Novartis is currently developing the 2 mL pre-filled syringe and the 2 mL auto-injector 
containing 300 mg of secukinumab. 
As of 25 June 2017, over 28 000 subjects have been enrolled in studies with secukinumab, with 
over 25000 having received secukinumab at doses ranging from 0.1 mg/kg to 30 mg/kg 
intravenously (i.v.), and from 25 mg to 300 mg subcutaneously (s.c.), given as single or multiple 
doses. As of 25 June 2017, there are over 50 completed and multiple ongoing trials conducted 
with secukinumab in indications including psoriasis, psoriatic arthritis (PsA), ankylosing 
spondylitis, uveitis, multiple sclerosis, rheumatoid arthritis, rheumatic polymyalgia, type I 
diabetes mellitus, and asthma. These studies support a favorable safety profile without 
indication of any specific organ toxicity. The Novartis Investigator’s Brochure (IB) provides a 
more detailed review of the pre-clinical and clinical information on secukinumab. The aim of 
the present study is to assess the efficacy, safety, 
 and local 
tolerability of a 2 mL auto-injector of 300 mg secukinumab. 
 
1.2 
Purpose 
The purpose of this study is to demonstrate efficacy of secukinumab 300 mg in 2 mL auto- 
injector at Week 12 based on PASI and IGA mod 2011 response rates versus placebo in subjects 
with moderate to severe plaque-type psoriasis. 
Moreover this study will assess the efficacy, safety and tolerability of secukinumab when used 
for 52 weeks as well as usability (ability to follow instruction for use and potential use-related 
hazards) of the 2 mL AI. 
As a result, this study will provide efficacy, 
 and safety data (
) 
to support the registration of the secukinumab 300 mg in 2 mL AI.

Study design 
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group trial in 
approximately 120 subjects with moderate to severe plaque-type psoriasis. 
It is expected that subjects will be enrolled at around 30 study sites worldwide. 
The study consists of 3 periods: 
• Screening Period (of at least 1 week and up to 4 weeks between Screening and 
Randomization) 
The screening period is used to assess eligibility of the subjects and to taper subjects off 
prohibited medications. 
• Treatment Period 1 (of 12 weeks, double-blind between Randomization and Week 12 pre- 
dose) 
The Treatment Period 1 starts with the randomization of eligible subjects followed by the first 
dosing. At the start of Treatment Period I, eligible subjects will be randomized at a 2:2:1:1 ratio 
to one of the four treatment groups (Section 6.1.1). In order to achieve a balanced weight 
distribution in each treatment arm, randomization in these four groups will be stratified by body 
weight at baseline (< 90 kg or ≥ 90 kg). Subjects are then visiting the study site at Week 1, 2, 
3, 4, 8 and 12, where they will receive study treatment (secukinumab 300 mg 2 mL AI, 
secukinumab 300 mg 2 x 1mL PFS, or placebo). 

Novartis 
Clinical Trial Protocol (Version 00)

Assessments for the primary endpoints are done for all treatment arms at Week 12 prior to 
dosing. This time-point is the End of Treatment Period 1 (EOT1). 
• Treatment Period 2 (of 40 weeks, double-blind between Week 12 dosing and Week 52) 
The Treatment Period 2 is a maintenance period for the study treatment and starts with the Week 
12 dosing. Doses of study treatment are then self-administered weekly up to Week 16 and every 
four weeks up to Week 48 for all treatment arms. 
Week 52 is the planned End of Treatment Period 2/End of Study (EOT2/EOS). 
Subjects who prematurely discontinue study treatment must perform EOT1 or EOT2/EOS 
approximately four weeks after their last dose of study treatment, depending if they are in 
Treatment Period 1 or 2, respectively. 
Safety, efficacy 
 will be performed 
according to the visit schedule as described in Table 8-1.

Rationale 
4.1 
Rationale for study design 
The intent of this study is to assess a 2 mL auto-injector form for the administration of 300 mg 
of secukinumab instead of two injections of 1 mL pre-filled syringes of 150 mg each, to 
psoriasis subjects that are treated with secukinumab at the recommended dose. 

Novartis 
Clinical Trial Protocol (Version 00)

This 52-week, double-blind, randomized, parallel-group, and placebo-controlled study is using 
the recommended dose of 300 mg secukinumab which has been approved for the treatment of 
moderate to severe psoriasis in adults. 
The study has been designed in accordance with Health Authorities guidelines and feedback on 
the clinical development program for the 2 mL auto-injector, including the United States Food 
and Drug Administration (FDA). The principle of a 2 mL s.c. injection is supported by a patient 
education document published by the National Institute of Health (NIH) that outlines the 
possibility to administer more than 1 mL of volume (NIH 2016). Based upon a recently 
conducted Novartis relative bioavailability study (CAIN457A2107) that assessed the 300 mg 
dose with a 2 mL s.c. injection using different devices, the pharmacokinetic data with 2 mL s.c. 
were similar to two marketed forms of 1 mL s.c. (pre-filled syringe and auto-injector/pen) and 
safety data showed no issues with 2 mL s.c. injections, including local tolerability. Therefore, 
it is appropriate to initiate study CAIN457A2325. 
The primary endpoint of this study is at Week 12. This will allow for assessment of efficacy at 
a point in time for which efficacy data of current approved biologic therapies are available and 
which was the primary endpoint for the phase III studies with secukinumab in psoriasis, 
including those studies that introduced the liquid formulations (1 mL pre-filled syringe in 
CAIN457A2308, and 1 mL auto-injector in CAIN457A2309; Blauvelt et al 2014, Paul C et al 
2015). 
Overall, this study will assess the efficacy, 
 safety (
) and 
tolerability of secukinumab when used both, short-term (up to 12 weeks) and long-term (up to 
52 weeks) and includes an usability and satisfaction assessment (ability to follow instruction 
for use and potential use-related hazards) and satisfaction) of secukinumab with a 2 mL auto- 
injector. These data will support the registration of secukinumab 300 mg 2 mL auto-injector. 
The subject population will be described in more detail in Section 5 below. 
 
4.2 
Rationale for dose/regimen and duration of treatment 
The placebo-controlled study design was chosen to demonstrate the efficacy of 300 mg 
secukinumab administered with a 2 mL auto-injector in adult subjects suffering from moderate 
to severe psoriasis compared to placebo. The selected dose regimen for this study with an initial 
weekly schedule up to 4 weeks followed by a s.c administration of every four weeks up to Week 
48 is in line with the posology and method of administration as described in the approved 
product labelling. The selected design with the two injections of secukinumab 1 mL pre-filled 
syringes will also allow the comparison of the 
 and safety profile with the secukinumab 300 
mg 2 mL auto-injector. 
 
4.3 
Rationale for choice of comparator 
Due to the nature of psoriasis and the outcome measures for the primary and the key secondary 
endpoints used (PASI 75, 90 and IGA mod 2011 0 or 1), a placebo arm is necessary for reliable 
results on efficacy and safety. Moreover, the inclusion of a placebo group is in accordance with 
health authority guidelines (CHMP Psoriasis Guideline 2004). The duration of 3 months 
treatment within the placebo group up to the primary endpoint at Week 12 is accepted for 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 22
0 Protocol No. 
 
 
the indication of plaque-type psoriasis. Subjects from the placebo group that will not achieve 
PASI 90 after Week 12 will receive secukinumab. 
An arm with secukinumab 300 mg as 2 injections of 1 mL PFS has been added to assess 
 
 and as a reference for comparisons of efficacy and safety with secukinumab 300 
mg 2 mL AI. 
 
4.4 
Purpose and timing of interim analyses/design adaptations 
An analysis is planned to be performed after all subjects have completed the Week 16 visit to 
assess the 
 data up to Week 16 with the coprimary endpoints. 
All data up to Week 16 will be collected with the clinical team being blinded. The designated 
Novartis personnel (eg, statistician, programmer and a clinical representative) will be unblinded 
following database lock for the Week 16 analysis after all subjects have completed Week 16. 
Investigators, site personnel, and subjects will remain blinded until the end of the study. 
It is planned that data from the Week 16 analysis will be used for submission to the Health 
Authorities. Trial modifications are not planned based on any Week 16 analysis. 
Additional analyses are not planned, they may be performed to support Health Authorities 
interactions, as necessary. 
 
4.5 
Risks and benefits 
Secukinumab (Cosentyx®) 300 mg has been approved in moderate to severe psoriasis based on 
substantial clinical benefit and a favorable safety profile. 
Approximately 4,000 patients with moderate to severe plaque psoriasis were included in studies 
in the registration program. This included 3,430 subjects treated with secukinumab in 10 phase 
II/III studies, 2,727 of whom were treated for at least 6 months and 2,029 of whom were treated 
for at least 48 weeks. 
Superiority of secukinumab to placebo was demonstrated for the co-primary efficacy criteria of 
PASI 75 and IGA mod 2011 0 or 1 at 12 weeks in all 4 pivotal placebo-controlled trials (> 62% 
for PASI 75 and > 48% for IGA mod 2011 0 or 1). Secukinumab was also found to be superior 
in efficacy compared to etanercept with a rapid onset of action in the etanercept and placebo- 
controlled studies, CAIN457A2302 and CAIN457A2303 and superior to ustekinumab in 
CAIN457A2317. The safety data from the completed and ongoing studies including AE and 
SAE data, laboratory parameters and 
 data demonstrate a favorable safety 
profile. Observed risks included infections in particular upper respiratory tract infections, 
neutropenia and hypersensitivity reactions that can be seen with administration of foreign 
proteins. Most of the infections were non-serious, mild to moderate in severity, clinically easily 
manageable and did not lead to treatment discontinuation. Cases of neutropenia were 
uncommon, generally mild to moderate and transient and did not lead to treatment 
discontinuation, and only a few cases were temporally associated with non-serious infections. 
Subjects with pre-existing malignancies within the past 5 years are generally excluded from 
studies with secukinumab although there is no scientific basis to suggest that secukinumab 
would increase the risk for malignancies. Indeed, the majority of preclinical data, available in 
the literature, suggest that blocking IL-17A may actually prevent tumor growth.

Indirect comparisons across phase III trials revealed that fewer injection site reactions were 
reported with secukinumab 1 mL pre-filled syringe (containing 150 mg secukinumab), 
compared to etanercept, while the active treatment groups were higher vs. placebo. 
In the phase III studies CAIN457A2308 and CAIN457A2309, evaluating the safety and efficacy 
of secukinumab in liquid formulation in the 1 mL pre-filled syringe and 1 mL pre-filled 
pen/auto-injector, respectively, the data showed that the PASI response with both 150 mg and 
300 mg doses were superior to placebo (p < 0.0001). Comparing the efficacy and safety results 
across the phase III trials, the response rates in trials A2308 and A2309 were generally similar 
to those of the trials involving the lyophilized form (studies A2302 and A2303). It is expected 
that the 2 mL pre-filled syringe and 2 mL pre-filled pen/auto-injector are also comparable and 
have the same efficacy and safety profile as the liquid formulation remains the same. 
A recent relative bioavailability study (CAIN457A2107) to assess the pharmacokinetic 
parameters, safety and tolerability of a single administration of 300 mg secukinumab 
administered subcutaneously (s.c.) in healthy volunteers investigated several delivery systems 
to identify administration options for secukinumab. The data suggest that with a “simulated” 2 
mL pre-filled syringe (i.e.,. manual injection of 2 mL 300 mg in 10 seconds) i/ the 
pharmacokinetic profiles are similar to the 1 mL pre-filled syringe (with 2 injections), ii/ the 
tolerability (pain score) is acceptable, iii/ local reactions such as erythema, induration, 
hemorrhage, pruritus and leakage are minimum and finally, iv/ the safety profile is also similar 
to the 1 mL pre-filled syringe (with 2 x 1 mL s.c. injections). The 2 mL “simulated” form 
represented the best option from that study to provide the subjects with a simple easy to use 
single-injection device for the treatment of psoriasis. 
The principle of a 2 mL s.c. injection in patients is supported by the Patient Education document 
from the US National Institute of Health (NIH) that outlines the possibility to administer more 
than 1 mL of volume (NIH 2016). 
All quality, non-clinical pharmacology and toxicology data, as well as the available clinical 
efficacy and safety data, are considered sufficient to expect a positive benefit/risk ratio for the 
treatment of psoriasis with secukinumab with the 2 mL 300 mg auto-injector, and therefore it 
is appropriate to initiate study CAIN457A2325 for registration purposes. 
The risk to subjects in this trial will be minimized by compliance with the eligibility criteria 
and study procedures, and close clinical monitoring 
Women of child bearing potential and sexually active males must be informed that taking the 
study treatment may involve unknown risks to the fetus if pregnancy were to occur during the 
study, and agree that in order to participate in the study they must adhere to the contraception 
requirements outlined in the exclusion criteria. If there is any question that the subject will not 
reliably comply, they should not be entered or continue in the study.

hysterectomy), total hysterectomy or tubal ligation at least six weeks before taking 
study treatment. In case of oophorectomy alone, only when the reproductive status of 
the woman has been confirmed by follow-up hormone level assessment. 
• Male sterilization (at least 6 months prior to screening). For female subjects on the 
study, the vasectomized male partner should be the sole partner for that subject. 
• Barrier methods of contraception: Condom or Occlusive cap (diaphragm or 
cervical/vault caps). For UK: with spermicidal foam/gel/film/cream/vaginal 
suppository. 
• Use of oral, (estrogen and progesterone), injected or implanted hormonal methods of 
contraception or other forms of hormonal contraception that have comparable efficacy 
(failure rate < 1%), for example hormone vaginal ring or transdermal hormone 
contraception or placement of an intrauterine device or intrauterine system. 
In case of use of oral contraception women should have been stable on the same pill for a 
minimum of 3 months before taking study treatment. 
In case local regulations deviate from the contraception methods listed above, local regulations 
apply and will be described in the Informed Consent Form (ICF). 
Women are considered post-menopausal and not of child bearing potential if they have had 12 
months of natural (spontaneous) amenorrhea with an appropriate clinical profile (eg, age 
appropriate history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with 
or without hysterectomy), total hysterectomy or tubal ligation at least six weeks ago. In the case 
of oophorectomy alone, only when the reproductive status of the woman has been confirmed 
by follow-up hormone level assessment is she considered not of child bearing potential. 
8. Active ongoing inflammatory diseases other than psoriasis and psoriatic arthritis (PsA) that 
might confound the evaluation of the benefit of secukinumab therapy. Also, underlying 
conditions (including, but not limited to metabolic, hematologic, renal, hepatic, pulmonary, 
neurologic, endocrine, cardiac, infectious or gastrointestinal) which in the opinion of the 
investigator significantly immunocompromises the subject and/or places the subject at 
unacceptable risk for receiving an immunomodulatory therapy. In addition, current severe 
progressive or uncontrolled diseases which renders the subject unsuitable for the trial or 

Novartis

puts the subject at increased risk, including any medical or psychiatric condition which, in 
the Investigator’s opinion, would preclude the participant from adhering to the protocol or 
completing the study per protocol. 
9. Presence of : 
• Significant medical problems, including but not limited to the following: uncontrolled 
hypertension (repeated values of systolic BP ≥ 160 mmHg and/or diastolic BP ≥ 95 
mmHg), congestive heart failure (New York Heart Association status of class III or IV). 
• Serum creatinine level exceeding 2.0 mg/dL (176.8 µmol/L). 
• Total white blood cell (WBC) count < 2,500/µL, or platelets < 100,000/µL or 
neutrophils < 1,500/µL or hemoglobin < 8.5 g/dL at Screening. 
10. Active systemic infections during the last two weeks (exception: common cold) prior to 
randomization or any infection that reoccurs on a regular basis. 
11. History of an ongoing, chronic or recurrent infectious disease, or evidence of tuberculosis 
(TB) infection as defined by a positive central laboratory test result at screening. Subjects 
with a positive test result may participate in the study if further work up (according to local 
practice/guidelines) establishes conclusively that the subject has no evidence of active 
tuberculosis. If presence of latent tuberculosis is established, then treatment must have been 
initiated and maintained according to local country guidelines prior to randomization. 
12. Past medical history record or current infection with Human Immunodeficiency Virus, 
hepatitis B or hepatitis C prior to Randomization. 
13. History of lymphoproliferative disease or any known malignancy or history of malignancy 
of any organ system treated or untreated within the past 5 years, regardless of whether there 
is evidence of local recurrence or metastases (except for Bowen’s disease, or basal cell 
carcinoma or actinic keratoses that have been treated with no evidence of recurrence in the 
past 12 weeks; carcinoma in situ of the cervix or non-invasive malignant colon polyps that 
have been removed). 
14. Inability or unwillingness to undergo repeated venipuncture (eg, because of poor tolerability 
or lack of access to veins) or to self-administer sub-cutaneous injections. 
15. History or evidence of ongoing alcohol or drug abuse, within the last six months before 
Randomization. 
16. History of hypersensitivity to any of the study treatments or its excipients or to drugs of 
similar chemical classes.

Control treatment: 
• 
Secukinumab 300 mg, provided as two 1 mL pre-filled syringes (PFS) containing 150 mg 
secukinumab 
• 
Secukinumab placebo, provided as either one 2 mL AI or two 1 mL PFS 
Secukinumab and the secukinumab-matching placebo will be labeled as “AIN457 300 mg / 
Placebo” (2 mL) or “AIN457 150 mg / Placebo” (1 mL) to keep the blind. 
The removable cap of the secukinumab PFS 1 mL form only contains a derivative of natural 
rubber latex (note: this is not applicable to the 2 mL AI). Although no natural rubber latex is 
detected in the cap, the safe use of the secukinumab 1 mL PFS in latex-sensitive individuals has 
not been studied. 
 
6.1.2 
Additional study treatments 
No other treatment beyond investigational drug and control drug are included in this trial. 
 
6.1.3 
Treatment arms/group 
Subjects will be randomized using a 2:2:1:1 ratio into one of the following 4 treatment arms. 
In order to achieve a balanced weight distribution in each treatment arm, randomization will be 
stratified by body weight at baseline, < 90 kg or ≥ 90 kg. 
• Group 1: Secukinumab 300 mg (2 mL AI) 
• Group 2: Secukinumab 300 mg (2 x 1 mL PFS) 
• Group 3: Placebo - Secukinumab 300 mg (2 mL AI) 
• Group 4: Placebo - Secukinumab 300 mg (2 x 1 mL PFS) 
During Treatment Period 1, subjects will self-administer three injections of study treatment at 
study sites (Table 8-1) once weekly at Randomization, Weeks 1, 2, and 3, followed by dosing 
at Week 4 and Week 8: 
• Group 1: one 2 mL secukinumab 300 mg AI plus two 1 mL PFS matching placebo 
secukinumab s.c. injections 
• Group 2: two 1 mL secukinumab 150 mg PFS plus one 2 mL AI matching placebo 
secukinumab s.c. injections 
• Group 3 and Group 4: will receive placebo treatment administered as two 1 mL placebo 
secukinumab 150 mg PFS plus one 2 mL AI matching placebo secukinumab s.c. injections 
The treatment of the 2 placebo groups will be the same during treatment Period 1 and will only 
differ after Week 12 in treatment period 2 for non-responders only. 
Prior to administration of the Week 12 dose, PASI 90 response status will be evaluated and 
subjects classified accordingly. Based on the PASI 90 responders status (per definition in 
Section 8.3.2) at the Week 12 visit, subjects on placebo will either remain on placebo during 
the Treatment Period 2 or be re-assigned to secukinumab 300 mg treatment. 
The 2 placebo groups will be considered as a single placebo arm for analysis purpose (up to 
Week 12).

mL PFS matching placebo secukinumab s.c. injections 
2. PASI 90 non-responders of Group 4: two 1 mL secukinumab 150 mg PFS plus one 2 
mL AI matching placebo secukinumab s.c. injections 
3. PASI 90 responders of Group 3 and Group 4: will continue to receive the same 
placebo treatment administered as two 1 mL placebo secukinumab 150 mg PFS plus 
one 2 mL AI matching placebo secukinumab s.c. injections. 
 
In addition, subjects will self-administer three injections of study treatment at study sites 
(Table 8-1) once weekly at Weeks 13, 14 and 15: 
• PASI 90 non-responders of placebo Group 3: one 2 mL secukinumab 300 mg AI plus 
two 1 mL PFS matching placebo secukinumab s.c. injections 
• PASI 90 non-responders of Placebo Group 4: two 1 mL secukinumab 150 mg PFS 
plus one 2 mL AI matching placebo secukinumab s.c. injections 
• Group 1, Group 2 and PASI 90 responders of Placebo Group 3 and Group 4: two 1

earlier at the discretion of the investigator or the subject 
 
6.2 
Other treatment(s) 
No additional treatment beyond investigational drug and control drug are included in this trial 
 
6.2.1 
Concomitant therapy 
The investigator must instruct the subject to notify the study site about any new medications 
he/she takes after the subject was enrolled into the study. All medications, procedures and 
significant non-drug therapies (including physical therapy and blood transfusions) administered 
after the subject was enrolled into the study must be recorded on the appropriate Case Report 
Forms. 
After Screening, the use of concomitant medication for psoriasis in all body regions is restricted 
to bland emollients (not supplied by Novartis) and other non-medicated interventions. Use of 
bland emollients must be recorded on the appropriate Case Report Forms and should be avoided 

Novartis

during the 12 hours preceding a scheduled visit. Use of any other non-medicated interventions 
should be recorded on the appropriate Case Report Forms. 
Each concomitant drug must be individually assessed against all exclusion criteria/prohibited 
medication. If in doubt the investigator should contact the Novartis medical monitor before 
randomizing a subject or allowing a new medication to be started. 
Any treatment known to worsen psoriasis (eg, beta-blockers, calcium channel blockers, lithium) 
should be stable at least 4 weeks before randomization. 
 
6.2.2 
Prohibited medication 
Use of any treatments displayed in Table 6-1 that could confound the efficacy of the 
investigational drug is NOT allowed during the study for any indication. All prohibited 
treatments should be washed out as shown in Table 6-1. 
The investigator should instruct the subject to notify the study site about any new treatments. 
At the discretion of the investigator, if any use of a prohibited treatment presents an undue 
safety risk for the subject, the study treatment must be discontinued. If a live vaccination has to 
be administered, the study treatment must be discontinued.

Subject numbering, treatment assignment, randomization 
6.3.1 
Subject numbering 
Each subject is identified in the study by a Subject Number (Subject No.), that is assigned when 
the subject is first enrolled for screening and is retained as the primary identifier for the subject 
throughout his/her entire participation in the trial. The Subject No. consists of the Center 
Number (Center No.) (as assigned by Novartis to the investigative site) with a sequential subject 
number suffixed to it, so that each subject is numbered uniquely across the entire database. 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 31
0 Protocol No. 
 
 
Upon signing the informed consent form, the subject is assigned to the next sequential Subject 
No. available. 
If a subject is re-screened for the study, then he/she must sign a new ICF and be issued a new 
Subject Number prior to any assessment being conducted for the subject under the new Subject 
Number 
 
6.3.2 
Treatment assignment, randomization 
At Randomization visit, all eligible subjects will be randomized via Interactive Response 
Technology (IRT) to one of the treatment arms. No re-randomization will be done at Week 12 
as the original randomization is already including the Period 2 treatment group to be assigned 
to for Non-responders of the placebo arm. The investigator or his/her delegate will contact the 
IRT after confirming that the subject fulfills all the inclusion/exclusion criteria. The IRT will 
assign one randomization number to the subject, which will be used to link the subject to a 
treatment arm and will specify a unique medication number for the package of study drug to be 
dispensed to the subject. The randomization number will not be communicated to the subject. 
The randomization numbers will be generated using the following procedure to ensure that 
treatment assignment is unbiased and concealed from subjects and investigator staff. A subject 
randomization list will be produced by the IRT using a validated system that automates the 
random assignment of subject 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 
Global Clinical Supplies using a validated system that automates the random assignment of 
medication numbers to packs containing the investigational drug(s) 
If a subject discontinues before Randomization, the IRT should be notified within five days and 
the reason for not being randomized should be recorded on the appropriate Case Report Forms. 
Randomization will be stratified by body weight assessed at baseline. Stratification ensures a 
balanced allocation of subjects to treatment groups within the two weight strata: “body weight 
< 90 kg” or “body weight ≥ 90 kg”. 
The randomization scheme for subjects will be reviewed and approved by a member of the 
Randomization Office. 
 
6.4 
Treatment blinding 
A double-dummy design is used to ensure that the identity of the study drug cannot be disguised, 
as the drug products are visibly different. 
Subjects, investigator staff and persons performing the assessments, and data analysts will 
remain blind to the identity of the study treatment from the time of randomization until the end 
of study 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 else involved in the study with the following exceptions: 
• 
Specific vendors whose role in trial conduct requires their unblinding (eg, IRT) 
• 
Global Clinical Supplies 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 32
0 Protocol No. 
 
 
• 
The designated Novartis study team members involved in the primary endpoint analysis, 
as described in Section 4.4. 
2. 
The identity of the treatments will be concealed by the use of investigational treatments 
that are all identical in packaging, labeling, schedule of administration, appearance, taste and 
odor. 
Unblinding will only occur in the case of subject emergencies, at the time of the endpoint 
analysis as described below. The blind will be kept until the final database lock. 
 
 
The appropriate personnel from the study site and Novartis will assess whether study 
treatment should be discontinued for any subject whose treatment code has been broken 
inadvertently for any reason. Study treatment must be discontinued after emergency 
unblinding (Section 6.6.2). 
 
6.5 
Dose escalation and dose modification 
Study treatment dose adjustments and/or interruptions are not permitted. However a positive 
urine pregnancy test during the study requires immediate interruption of study treatment until 
serum pregnancy test is performed and found to be negative. If the serum test is positive, study 
treatment must be permanently discontinued. 
 
6.5.1 
Follow-up for toxicities 
Not applicable. 
 
6.6 
Additional treatment guidance 
6.6.1 
Treatment compliance 
All doses of study treatment administration will be recorded on the appropriate case report 
form. Compliance will also be assessed and confirmed by a field monitor by drug accountability 
logs, by documentation and information provided by IRT and by the qualified site personnel 
that is responsible for treatment dispensation, preparation, administration and accountability. 
Cross-checks should be performed in case of home administrations and empty medication 
boxes/outer packing/devices should be collected (as permitted by local regulations) for 
compliance checks by field monitors. 
 
6.6.2 
Emergency breaking of assigned treatment code 
Emergency code breaks must only be undertaken when it is required to in order to treat the 
subject safely. Most often, study treatment discontinuation and knowledge of the possible 
treatment assignments are sufficient to treat a study subject 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 subject, he/she must provide the 
requested subject identifying information and confirm the necessity to break the treatment code 
for the subject. The investigator will then receive details of the investigational drug treatment 
for the specified subject and a fax or email confirming this information. The system will 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 33
0 Protocol No. 
 
 
automatically inform the Novartis monitor for the site and the study team that the code has been 
broken. 
It is the investigator’s responsibility to ensure that there is a dependable procedure in place to 
allow access to the IRT at any time in case of emergency. The investigator will provide: 
• protocol number 
• study drug name (if available) 
• subject number 
In addition, oral and written information to the subject must be provided on how to contact 
his/her back-up in cases of emergency, or when he/she is unavailable, to ensure that un-blinding 
can be performed at any time. 
 
6.7 
Preparation and dispensation 
Each study site will be supplied with study drug in packaging as described under investigational 
and control drugs section. 
A unique medication number is printed on the study medication label. 
Investigator staff will identify the study medication kits to dispense to the subject by contacting 
the IRT and obtaining the medication number(s). The study medication has a 2-part label (base 
plus tear-off label), immediately before dispensing the medication kit to the subject, site 
personnel will detach the outer part of the label from the packaging and affix it to the source 
document. 
 
6.7.1 
Handling of study treatment and additional treatment 
 
6.7.1.1 
Handling of study treatment 
Study 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 designated 
site personnel have access. Upon receipt, all study treatment must 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 CO 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 study treatment but no information about 
the subject except for the medication number. 
The investigator must maintain an accurate record of the shipment and dispensing of study 
treatment in a drug accountability log. Monitoring of drug accountability will be performed by 
monitors during site visits or remotely and at the completion of the trial. Subjects will be asked 
to return all unused study treatment and packaging at the end of the study or at the time of 
discontinuation of study treatment. 
The subjects will record the date(s) of administration at home on a diary/form and will return 
the used medication and packaging at their next visit to the site. Subjects will be asked to return 
all unused medication and packaging the latest at the completion of the study or at the time of 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 34
0 Protocol No. 
 
 
discontinuation of the investigational treatment. Site staff will record in the appropriate 
documents the dates of the administration. Detailed instructions will be provided separately. 
At the conclusion of the study, and as appropriate during the course of the study, the investigator 
will return all unused study 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. 
 
6.7.1.2 
Handling of additional treatment 
Not applicable. 
 
6.7.2 
Instruction for prescribing and taking study treatment 
All doses of study treatment (secukinumab and/or placebo) will be self-administered by the 
subject either at the study site or at home. 
The first use at Randomization and the Visit Week 1 assessments of the self-injection will take 
place in the context of an observed assessment under the supervision of one site staff member. 
Each assessment will be conducted on a 1:1 basis. 
At the Randomization Visit the subjects will be instructed by the site staff walking them through 
the Instructions For Use (IFU) on how to self-inject via the PFS and AI (the IFU brochure 
containing detailed information about self-administration of study treatment should be provided 
to 
each 
subject 
at 
the 
beginning 
of 
the 
study). 
After 
providing 
detailed 
explanations/instructions, subjects will then be asked to raise any questions. Thereafter, they 
will proceed with self-injection. At Week 1 subjects will be asked to refer to the IFU and to 
proceed with self-injection of the actual study drug (i.e., without a detailed 
explanation/instruction on handling the syringe and auto-injector). At Randomization and 
Week 1, site staff will observe and complete the self-injection assessment checklist (Table 8-5) 
and the possible hazard assessment check list (Table 8-6) for the 2 mL auto-injector. 
Home administrations should be done at pre-defined visits (Table 8-1) and can be performed 
by the subject. If self-administration is not chosen, these administrations can be performed by 
a trained caregiver. If the subject or caregiver is not able/confident to perform home 
administration, the subject will be allowed to return to the site for administration of the 
medication. However, during those site visits no additional assessments will be required. 
During home administrations subjects are expected to contact the investigator/site staff in case 
they are experiencing any AE/SAEs or have any concerns. 
 
Administration 
All doses of study treatment that are administered at the study site should be performed after 
the study assessments for the visit, including blood sampling and the completion of DLQI 
questionnaire by the subjects, have been completed. 
The first study treatment administration will occur at the Randomization/baseline Visit, after 
all study scheduled assessments have been performed (and inclusion/exclusion criteria 
confirmed) and only after the scheduled blood samples have been drawn. 

Novartis 
Clinical Trial Protocol (Version 00)

The study treatment solutions must be self-injected subcutaneously in non-affected areas of the 
skin starting with the 2 mL AI, the 2 injections of 1 mL PFS taking place subsequently, after 
completion of the SIAQ, when applicable. Administration of study treatment may vary on the 
body regions, i.e., changing the injection site from visit to visit: right thigh, left thigh, right 
stomach, left stomach, upper outer arm (when assisted by attendant), whilst separating the 2 mL 
AI and the two 1 mL PFS injection sites. Used syringes and AI should be disposed immediately 
after use in a sharps container or according to the regulatory needs of the respective countries. 
More information can be found in the study-specific IFU. 
All dates and times of injections during the study must be recorded on the appropriate CRF. 
All kits of study treatment assigned by the IRT will be recorded/databased in the IRT. 
The investigator must promote compliance by instructing the subject to take the study treatment 
exactly as prescribed and by stating that compliance is necessary for the subject’s safety and 
the validity of the study. The subject must also be instructed to contact the investigator if he/she 
is unable for any reason to take the study treatment as prescribed.

Informed consent procedures 
Eligible subjects may only be included in the study after providing (witnessed, where required 
by law or regulation), IRB/IEC-approved informed consent. 
If applicable, in cases where the subject's representative(s) gives consent (if allowed according 
to local requirements), the subject must be informed about the study to the extent possible given 
his/her understanding. If the subject is capable of doing so, he/she must indicate agreement by 
personally signing and dating the written informed consent document. 
Informed consent must be obtained before conducting any study-specific procedures (eg, all of 
the procedures described in the protocol). The process of obtaining informed consent must be 
documented in the subject source documents. 
Novartis will provide to investigators in a separate document a proposed informed consent form 
that complies with the International Council for Harmonisation of Technical Requirements for 
Pharmaceuticals for Human Use (ICH) Good Clinical Practice (GCP) guidelines and regulatory 
requirements and is considered appropriate for this study. Any changes to the proposed consent 
form suggested by the investigator must be agreed by Novartis before submission to the 
IRB/IEC. 
Information about common side effects already known about the investigational drug can be 
found in the Investigator's Brochure (IB). This information will be included in the subject 
informed consent and should be discussed with the subject during the study as needed. Any new 
information regarding the safety profile of the investigational drug that is identified between IB 
updates will be communicated as appropriate, for example, via an investigator notification (IN) 
or an aggregate safety finding. New information might require an update to the informed 
consent and then must be discussed with the subject. 
Women of child bearing potential must be informed that taking the study treatment may involve 
unknown risks to the fetus if pregnancy were to occur during the study and agree that in order 
to participate in the study they must adhere to the contraception requirements.

A copy of the approved version of all consent forms must be provided to Novartis/sponsor after 
IRB/IEC approval.

Visit schedule and assessments 
Assessment schedule lists all of the assessments and when they are performed. All data obtained 
from these assessments must be supported in the subject’s source documentation. 
Subjects should be seen for all visits as outlined in the assessment schedule or as close to the 
designated day/time as possible. Every effort should be made to respect the timeframe for all 
visits and particularly when 
. Missed or rescheduled visits should not 
lead to automatic discontinuation. Subjects who prematurely discontinue the study for any 
reason should be scheduled for the final visit as soon as possible at which time all of the 
assessments listed for the final visit will be performed. At this final visit, all dispensed 
investigational product should be reconciled, and the adverse events and concomitant 
medications recorded on the CRF. 
For subjects who discontinue study treatment prematurely for any reason other than withdrawal 
of informed consent or loss to follow-up procedures as described in Section 9 should be 
followed. 
During Treatment Periods 1 and 2, subjects may be seen at an unscheduled visit, eg, if they 
experience deterioration of psoriasis, or AEs that in the opinion of the investigator need 
intervention or repeated laboratory testing. During these unscheduled visits, study treatment 
will NOT be administered. The assessment(s) performed at an unscheduled visit are at the 
investigator’s discretion. 
Order of assessments 
Guidance for the order of assessments as shown in Table 8-1 is as follows (may vary depending 
on different type of visits): 
Investigator / Qualified Site Staff 
1. IGA mod 2011 
2. PASI 
3. Other procedures 
• All remaining study visit procedures (eg, laboratory and 
 
 collection, vital 
signs measurements) must be completed prior to study treatment administration. 
• Enter PASI and IGA mod 2011 assessments into eCRFs BEFORE contacting IRT at 
Randomization Visit and EOT1 Visit Week 12. 
• Contact IRT to register the subject visit. 
• Prepare the corresponding study medication packs as indicated in the study-specific 
IFU brochure (dispense for home administrations, as required). 
• Provide guidance to subjects for self-administration prior to the first treatment 
administration (Section 6.7.2) at Randomization; from Visit Week 1 until End of 
Treatment Period 2 subjects should refer to the IFU and proceed with self-

administrations either at the site or they receive instructions for sub-sequent home 
administrations. 
• Auto-injector usability and hazard assessment should be done by site personnel, at 
Randomization Visit and at Visit Week 1 while the injections with the 2 mL AI are 
self-administered by the subject prior to the 1 mL PFS injection. 
 
Subjects 
• Subjects must complete the DLQI prior to any investigator assessments. 
• SIAQ PRE module must be completed once at Randomization prior to the first injection with 
the 2 mL AI. 
• SIAQ POST module, must be completed after the injections with the 2 mL AI as shown in 
Table 8-1. 
The 1 mL PFS injection should follow the SIAQ POST.

8.1 
Screening 
Screening 
If for any reason the subject is a screen failure, the subject may be re-screened. There is no 
restriction on the number of times a potential subject may be re-screened or on how much time 
must pass from the date of screen failure and the date of re-screening. 
If a subject is re-screened for the study, then the subject must sign a new ICF and be issued a 
new Subject Number prior to any assessment being conducted for the subject under the new 
Subject Number. The investigator/qualified site staff will record if the subject was re-screened 
on the re-screening section of the eCRF and any applicable screening numbers the subject was 
issued prior to the current screening number. The date of the new informed consent signature 
must be entered on the appropriate eCRF page to correspond to the new screening subject 
number. For re-screening, all screening assessments must be performed per protocol, except for 
the tuberculosis (TB) work up (including any chest x-ray), if applicable, if performed not more 
than 12 weeks before randomization. 
 
8.1.1 
Information to be collected on screening failures 
Subjects who sign the ICF and discontinue prior to randomization at the Randomization Visit 
are considered screening failures. IRT must be notified within five days and the reason for not 
being randomized will be entered in the appropriate eCRF page. The Screening Visit date, the 
Demography, Informed Consent, and Inclusion/Exclusion Criteria eCRF sections should be 
completed. The Adverse Event eCRF section and a SAE Form should be completed for any 
SAE that occurred during the Screening Period. Adverse events that are not SAEs will be 
followed by the investigator and collected only in the source data. The Withdrawal of consent 
eCRF section should be completed if consent was withdrawn prior to the randomization. 
 
8.2 
Subject demographics/other baseline characteristics 
Country specific regulations should be considered for the collection of demographic and 
baseline characteristics in alignment with CRF 
 
8.2.1 
Demographics 
Subject demographic data will include: age (in years), sex, race, ethnicity, and child-bearing 
potential (for females only). 
 
8.2.2 
Psoriasis medical history/previous psoriasis therapies 
The following information should be collected and entered in the eCRF section in addition to 
pre-psoriasis therapies: 
• The date of first diagnosis of plaque-type psoriasis 
• The date of first diagnosis of other locations or clinical forms of psoriasis, eg: 
• Generalized pustular or pustular palmoplantar psoriasis 
• Guttate, palmoplantar, nail, inverse, scalp or erythrodermic psoriasis 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 42

• The previous treatments of psoriasis (including previous use of biologic therapies, as well 
as phototherapy and/or photochemotherapy) and the reason for discontinuation 
• The presence of psoriatic arthritis and date of first diagnosis 
8.2.3 
Smoking history 
The current and/or previous use of tobacco products will be recorded prior to randomization, as 
well as the estimated number of pack-years based on the approximate consumption per year. 
Non-smokers will be advised to not start smoking during the study. 
 
8.2.4 
Cardiovascular medical history 
Any information pertaining to cardiovascular medical history assessed prior to randomization 
should be recorded on the appropriate case report form. 
 
8.2.5 
Medical history 
Relevant medical history and current medical conditions present before signing the informed 
consent should be recorded on the appropriate eCRF section. Whenever possible, diagnoses and 
not symptoms should be recorded. 
Any information pertaining to psoriasis or cardiovascular medical history assessed prior to 
randomization should be reported on the corresponding eCRF sections, see above. 
 
8.2.6 
Determination of the tuberculosis status 
Determination of the TB status should be done at Screening and should be performed as defined 
by local guidelines. The TB status must be determined by medical history, signs, symptoms, 
TB testing. Any significant findings should be recorded on the appropriate eCRF page 
(Tuberculosis assessment or medical history as deemed necessary) (See Appendix 6 for more 
details). 
 
8.3 
Efficacy 
The following order should be applied when performing the efficacy assessments at study 
visits: 
• IGA mod 2011 
• PASI 
8.3.1 
Investigator’s Global Assessment (IGA mod 2011) 
It is recommended that the same evaluator conduct the assessment throughout the study 
whenever possible. 
The IGA mod 2011 used in this study is static, i.e., it refers exclusively to the subject’s disease 
state at the time of the assessments, and does not attempt a comparison with any of the subject’s 
previous disease states, whether at Randomization or at a previous visit. 
The IGA mod 2011 score will be recorded in the eCRF.

Based on this scale, the following criteria apply: 
• 
A subject will be eligible to participate in the study if she/he has an IGA mod 2011 score 
at the Randomization Visit of 3 or 4. 
• 
A subject will be considered as IGA mod 2011 0 or 1 responder if she/he achieves a score 
of 0 or 1, and improved by at least 2 points on the IGA scale at a given time point 
compared to baseline. 
 
8.3.2 
Assessment of total Body Surface Area (BSA) and Psoriasis Area 
Severity Index (PASI) 
The investigator or qualified designee will complete the PASI assessment. Whenever possible, 
PASI assessments should be performed by the same evaluator throughout the study. 
The total BSA affected by plaque-type psoriasis will be estimated as first step of PASI 
calculation from the percentages of areas affected, including head, trunk, upper limbs and lower 
limbs (see Table 8-3). The following calculations will be done: each reported percentage will 
be multiplied by its respective body region corresponding factor (head = 0.1, trunk = 0.3, upper 
limbs = 0.2, lower limbs = 0.4). The resulting 4 percentages will be added up to estimate the 
total BSA affected by plaque-type psoriasis. 
A PASI score (Fredriksson and Pettersson 1978, Weisman et al 2003, Gottlieb et al 2005) will 
be derived as indicated in Table 8-3. The head, trunk, upper limbs and lower limbs are 
assessed separately for erythema, thickening (plaque elevation, induration), and scaling 
(desquamation). The average degree of severity of each sign in each of the four body regions 
is assigned a score of 0-4. The area covered by lesions on each body region is estimated as a 
percentage of the total area of that particular body region. Further practical details help the 
assessment: 
The neck is assessed as part of the head. 
The axillae and groin are assessed as part of the trunk.

PASI 90 response: subjects achieving ≥ 90% improvement (reduction) in PASI score compared 
to Baseline are defined as PASI 90 responders 
PASI 100 response/remission: complete clearing of psoriasis (PASI = 0) 
Because the head and neck, upper limbs, trunk and lower limbs correspond to approximately 
10%, 20%, 30% and 40% of the surface body area, respectively, the PASI score is calculated 
using the following formula: 
PASI = 0.1(EH+IH+DH)AH + 0.2(EU+IU+DU)AU + 0.3(ET+IT+DT)AT + 0.4(EL+IL+DL)AL 
Further details regarding the formula are provided in Table 8-3. 
The definitions used in this study are based on Committee for Medicinal Products for Human 
Use (CHMP) guidelines for psoriasis (CHMP/EWP/2454/02 2004). 
PASI scores can range from a lower value of 0, corresponding to no signs of psoriasis, up to a 
theoretic maximum of 72.0. 
The PASI 90 responder status of all subjects will be calculated at the end of Treatment Period 
1, at Visit week 12. 
 
8.3.3 
Appropriateness of efficacy assessments 
PASI scores outcome measures, the assessment of the severity of the psoriasis symptoms and 
the extent to which the subject’s body area is affected by the disease, is mandated by the 
European Medicines Agency (EMA) for the clinical investigation of medicinal products for the 
treatment of psoriasis (CHMP/EWP/2454/02 2004). 
As indicated in Section 8.3.1, the IGA mod 2011 scale has been developed by Novartis in 
collaboration with Health Authorities, in particular the US FDA (Langley et al 2015). It has 
been used in phase III, IIIb, and IV secukinumab studies. In the modified scale, the two “very 
severe” and “severe” have been condensed into a single category, “severe” and the 
explanations/descriptions of the points on the scale have been improved to ensure appropriate 
differentiation between the points. 
 
 
8.4 
Safety/Tolerability 
Safety assessments are specified below with the assessment schedule detailing when each 
assessment is to be performed. 
Blood withdrawals and safety assessments should be done prior to study treatment 
administration and should be taken as shown in Table 8-1 and in Appendix 2.

Appropriate safety assessments (eg, evaluation of AEs and SAEs including injection site 
reactions) should be repeated after the dose is administered. For details on AE collection and 
reporting, refer to AE section (Section 10). 
 
Table 8-4 
Physical Assessments 
Assessment Specification 
 
A physical examination, including general appearance, skin, neck, eyes, ears, nose, 
throat, lungs, heart, abdomen, back, lymph nodes, extremities, vascular and 
neurological systems will be performed as indicated in Table 8-1. 
If necessary, based on medical history and/or symptoms, additional exams will be 
performed at the discretion of the investigator.

Whenever possible, assessments for an individual subject should be performed by 
the same member of the study site staff throughout the study. 
Information for all physical examinations must be included in the source 
documentation at the study site. Clinically relevant findings that are present prior to 
signing informed consent must be included in the Medical History part of the eCRF. 
Significant findings made after first administration of investigational drug which meet 
the definition of an AE must be recorded on the Adverse Event section of the eCRF 
Vital signs (including blood pressure and pulse measurements) will be assessed at 
every scheduled visit as indicated in Table 8-1. Whenever possible, assessments 
should be performed by the same study site staff member throughout the study. 
After the subject has been sitting for five minutes, with back supported and both feet 
placed on the floor, systolic and diastolic blood pressure will be measured twice 
(measurements separated by 1 to 2 minutes) using a validated device, with an 
appropriately sized cuff (Mancia et al 2007). In case the cuff sizes available are not 
large enough for the subject’s arm circumference, a sphygmomanometer with an 
appropriately sized cuff may be used. Measurements will be recorded in the source 
documentation and the average of the two measurements will be entered on the 
Vital Signs eCRF section. 
Normal blood pressure will be defined as a systolic pressure of 90 to < 120mmHg, 
and a diastolic blood pressure of 60 to < 80 mmHg under measurement conditions 
as outlined above. Notable blood pressure will be hypertension (systolic ≥ 140 
mmHg and/or diastolic > 90 mmHg) or hypotension (systolic < 90 mmHg and/or 
diastolic < 60 mmHg). A blood pressure indicative of pre-hypertension (systolic 120 
to < 140 mmHg and/or diastolic 80 to < 90 mmHg) will not be regarded as notable 
(Chobanian et al 2003). 
A normal pulse rate will be defined as a rate of 60 to 100 bpm(beats per minute) 
under the measurement conditions outlined above. Notable pulse rates are a rate 
below 60 bpm (bradycardia) or above 100 bpm (tachycardia). 
No specific action is pre-defined within this protocol to respond to specific abnormal 
vital signs, as it will be decided by the investigator whether and which specific action 
needs to be taken to respond to any abnormal values, taking into account the overall 
status of the subject. 
Height and body weight will be measured as listed in Table 8-1. 
Height and body weight will be measured in indoor clothing, but without shoes. 
Whenever, possible, body weight assessments should be performed by the same 
study site staff member; the same scale should be used throughout the study.

Laboratory evaluations 
A central laboratory will be used for analysis of all specimens listed below, unless noted 
otherwise. Details on the collections, shipment of samples and reporting of results by the central 
laboratory are provided to investigators in the laboratory manual. Refer to the Laboratory 
Manual for identification of laboratory reference range values and the schema for notification of 
site staff and Novartis for out of range values. 
Subjects should avoid smoking within the hour preceding the blood draws. 
Appendix 1 shows the extended laboratory ranges that are considered clinically notable. 
No specific action is pre-defined within this protocol to respond to specific abnormal 
laboratory values, as it will be decided by the investigator whether and which specific action 
needs to be taken to respond to any abnormal values, taking into account the overall status of 
the subject. 
 
8.4.1.1 
Hematology 
Hemoglobin, hematocrit, red blood cell count, white blood cell (WBC) count with differential 
(neutrophils including bands, lymphocytes, monocytes, eosinophils, basophils) and platelet 
count will be measured at all scheduled study visits, within the visit window suggested in 
Table 8-1. 
 
8.4.1.2 
Clinical chemistry 
Serum chemistry will include urea, creatinine, total bilirubin, Aspartate Aminotransferase 
AST (SGOT), Alanine Aminotransferase ALT (SGPT), Gamma-Glutamyl Transferase (GGT), 
alkaline phosphatase, sodium, potassium, bicarbonate, calcium, phosphorous, total protein, 
albumin, and uric acid. Serum chemistry will be measured at all scheduled study visits within 
the visit window specified in Table 8-1. 
 
8.4.1.3 
Fasting Laboratory evaluations 
Fasting (8 hour duration with water ad libitum) laboratory evaluations will be assessed as 
indicated in Table 8-1.

Urinalysis 
Dipsticks will be provided to the study sites for local urinalysis assessments. The sites will 
record the results in the appropriate CRF for each subject. Standard dipstick measurements for 
specific gravity, protein, glucose, pH, blood, urine blood dipstick (non-hemolyzed), urine blood 
dipstick (hemolyzed), bilirubin, ketones and WBC will be done as indicated in Table 8-1. 
If needed conditional microscopy assessments will be performed. 
Documentation related to urinalysis including results must be included in the source 
documentation at the study site. Clinically relevant findings that are present prior to signing 
informed consent must be included on appropriate eCRF page. Significant findings made after 
first administration of investigational drug which meet the definition of an AE must be recorded 
on the appropriate eCRF page. 
8.4.2 
Electrocardiogram (ECG) 
A standard single 12-lead ECG will be collected at Screening. The investigator/qualified site 
staff must review and initial the tracing. The original ECGs appropriately signed, should be 
collected and archived at the study site. 
ECGs must be recorded after 10 minutes rest in the supine position to ensure a stable baseline. 
The preferred sequence of cardiovascular data collection during study visits is ECG

collection first, followed by vital signs, and blood sampling. The Fridericia QT correction 
formula should be used for clinical decisions. 
ECG tracing filed in the study site source documents. ECGs with subject safety concerns, 
two additional ECGs should be performed to  confirm the safety finding. Although there is 
no exclusion criterion based on ECG results, the ECG at Screening must be reviewed for 
major abnormalities prior to enrollment into the study. 
Clinically significant abnormalities should be recorded on the relevant section of the CRF 
capturing medical history/ Current medical conditions/AE as appropriate. 
 
8.4.3 
Pregnancy 
A serum β-hCG test will be performed at Screening in all pre-menopausal women who are not 
surgically sterile. In addition, all women who are not sterilized or are of childbearing potential 
at Screening, a local urine pregnancy test must be performed as indicated in Table 8-1. 
Any woman with a confirmed positive pregnancy test during Screening is not eligible for 
randomization. A positive urine pregnancy test during the treatment periods of the study 
requires immediate interruption of study treatment until a serum β-hCG (Human Chorionic 
Gonadotropin) is performed and found to be negative. If the serum β-hCG test is positive, the 
subject must be discontinued from the study after follow-up assessments have been performed. 
 
8.4.4 
Appropriateness of safety measurements 
The safety assessments selected are standard measures for a biologic immunomodulating agent 
in Psoriasis. 
 
8.5 
Additional assessments 
The following additional assessments will be performed: 
• Clinician Reported Outcomes (ClinRO) 
• Usability and hazard assessment of the auto-injector 
• Patient Reported Outcomes (PRO) 
• SIAQ 
• DLQI 
• 
 
8.5.1 
Clinical Outcome Assessments (COAs) 
Clinician Reported Outcomes (ClinRO) 
Usability and hazard assessment of the auto-injector 
The goal is to measure and evaluate the usability of the auto-injector during observed use, as 
well as the assessment of the hazards with the auto-injector. 
Subjects will be instructed at Randomization through the site staff on how to self-inject via AI 
(and PFS) following the IFU. After explanations/instructions, the injection will be self- 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 50

administered by the subject into the appropriate injection site of the body. The delivery of the 
dose with the 2mL AI will be observed by investigator/site staff based on the 2 assessment 
check lists (see Table 8-5 and Table 8-6) at Randomization and Visit Week 1. Assessment of 
possible administration hazards will be based on identified hazards list (Table 8-6) as well as 
non-directed querying for any observed problems during self-injection. 
The First Use at Randomization and the Week 1 assessments will take place in the context of 
an observed assessment under the supervision of one site staff member. Each assessment will 
be conducted on a 1:1 basis. 
At the Randomization visit the subjects will be instructed through the site staff by walking them 
through the IFU on how to self-inject via AI (and PFS). Subjects will then be asked to raise any 
questions if they have any. Thereafter, they should proceed with self-injection. At Visit Week 
1 subjects will be asked to refer to the IFU and to proceed with self-injection of the actual study 
drug (i.e., without providing explanations/instructions). 
During the self-injections at the respective visits (Randomization and Week 1) site staff will 
observe and complete the 2mL self-injection assessment checklist (Table 8-5) and the possible 
hazard assessment check list (Table 8-6) for the auto-injector. 
The primary usability variables will be assessed based on binary (performed correctly: yes/no) 
response for the self-injection assessment check list. The possible hazard check list variables 
will be mainly assessed based on binomial (occurred: yes/no) response. Additionally, responses 
from the directed and non-directed querying for any observed problems and specification 
thereof during self-injection will be analysed on a case by case basis.

The following potential hazards from the Hazards Identified List ([AIN457_HID_Delta225-01]) have not 
been included as not being observable during self-injection observation: microbiological 
contamination, wrong drug, transfer of transmissible diseases. 
1 Excluding the actual injection into the appropriate injection site of the body 
2If yes, then it is to be specified under which circumstances breakage occurred and which parts were 
affected, as well any additional problems (eg, injuries) due to the breakage are to be described. 
3If yes, then it is to be specified. Possible events might include: irritated skin; drug too cold when 
injected; the drug or device upon visual inspection appeared unsuitable for injection; intradermal 
instead of subcutaneous injection; and other events. 
4If yes, then it is to be specified why, eg, leakage from injection site, early removal. 
During the self-injection the observing site staff member must exercise judgment and intervene 
in the self-administration should a subject not be acting in a safe or reasonable manner, or any 
manner which does not fall within the scope of the study objectives, including but not limited 
to: 
a. In the event that a subject performs (or is judged to be about to perform) a use error which 
could pose a risk to the health or well-being of a subject the observing site staff member 
will pause the subject to point out the error and decide whether it is better to terminate the 
self-injection. If in his or her judgment the self-injection can continue, he or she will 
correct the subject’s usage of the product and notify the subject to recommence at the 
same point. Any such use error will be documented. 
b. If there is, or appears to be, any risk of a health and safety incident including injury to any 
party. It is likely that this will require the self-injection to be terminated at the discretion 
of the observing site staff member. 
Any auto-injector for which a defect or malfunction is noticed prior to or during the injection 
at any of the study visits, must be kept at the site until guidance is received from Novartis on 
whether it should be returned to Novartis or discarded. Additionally, from Visit Week 2 
onwards, any noticed defect, malfunction, and problem during the injections or product 
complaints with the auto-injector should be recorded in the source document by the site, 
detailing the issue, the date and the visit number. It should also be reported to Novartis. 
Similarly, if such defects, malfunctions, problems during injections or product complaints are 
noticed by subjects during home administration, they must immediately be reported back to the 
sites, documented in detail in the source documents and reported to Novartis.

Primary usability assessment: 
This consist of the assessment of successful 2mL AI self-administration by the subject at 
Visit Week 1, by studying the number and percentage of subjects who successfully perform this 
self-injection (note: without prior explanations/instructions at this visit, as this has been 
performed prior to dosing at Randomization only). Successful self-injection is achieved when 
the subject performs all required steps effectively and safely to deliver the correct dose from 
the device at the correct injection site. The sequence of user steps as per IFU “required to be 
completed for successful administration” are identified in Table 8-5, these 4 critical steps will 
be used to define successful administration. The general passing usability goal for ‘successful 
use’ task completion will be defined as ≥ 90% pass rate of following these steps. 
 
Secondary usability assessment: 
• This consist of the assessment of 2mL AI subject use errors that occur during the First Use 
at Randomization (after providing initial explanations/instructions) and repeated self- 
injection at Visit Week 1 (without a detailed explanation/instruction on handling the new 
form) by investigating the frequency of observed or reported difficulties in completing the 
2mL AI self-injection after initial explanations/instructions and self-injection without 
explanations/instructions after a time lag that represents standard treatment. The number 
and percentage of subjects who successfully complete each of the indicated steps as per the 
IFU (Table 8-5 self-injection assessment check list) as well as the number and percentage 
of subjects who experience any of the defined possible hazards (based on identified hazards 
list) as well as non-directed querying for any observed problems during self-injection (Table 
8-6) will be computed by visit. 
• This consist of the assessment of successful First Use by subject after initial 
explanations/instructions, by studying the number and percentage of subjects at 
Randomization who successfully perform the self-injection as defined above for the primary 
usability assessment. 
 
8.5.1.1 
Patient Reported Outcomes (PRO) 
All subjects will complete the PRO questions via an electronic tablet. The subject should be 
given sufficient space and time to complete the questionnaires. In case of any issues with tablet 
use, which cannot be resolved within the visit time window subject can complete PRO questions 
on paper form. If subject experiences any difficulties with submission after they complete the 
PROs, the study staff should assist with submitting the PRO responses. Attempts should be 
made to collect responses to all PROs for all subjects, including from those who prematurely 
discontinue prior to the study evaluation completion visit, however, if subjects refuse to 
complete PROs, this should be documented in study source records. Subject’s refusal to 
complete study PROs are not protocol deviations. 
 
8.5.1.1.1 Self-Injection Assessment Questionnaire (SIAQ) 
The SIAQ measures the overall subject experience with subcutaneous self-injection, and to 
investigate the psychometric properties (Keininger and Coteur 2011, Appendix 4). The SIAQ 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 53
1 Protocol No. 
 
 
 
will be performed as a summary assessment for the auto-injector as outlined in the visit schedule 
(see Table 8-1). 
The SIAQ PRE module is to be self-completed before the first self-injection at Randomization. 
The SIAQ POST module is to be completed following the 2 mL AI self-injections and before 
the 1 mL PFS injections at the self-injections as the visits indicated in Table 8-1, including 
Randomization. 
The PRE module includes 7 items grouped into three domains: Feelings about injections, Self- 
confidence and Satisfaction with self-injection (see Appendix 4) 
The POST module includes several items addressing four principal domains: Feelings about 
injections, Self-confidence, Injection site reactions, Ease of use plus a single item assessing 
Self-image. 
The two modules of the SIAQ should be completed by subjects while alone in a quiet 
environment. The PRE module is completed immediately before the first self-injection and the 
POST module is completed 20-40 minutes after the 2 mL AI dosing but before the 1 mL PFS 
injection (three injections). There is no stipulated recall period for the SIAQ, because the recall 
period varies from one domain to another. For example, items from the injection-site reaction 
burden domain refer to the subject’s experience during or after the injection, whereas items 
from the general feelings about injections domain refer to general attitudes. Subjects should rate 
each item of the SIAQ on a 5-point semantic Likert-type scale, where a score of 1 corresponded 
to the subject’s worst experience and a score of 5 corresponds to the subject’s best experience. 
Item scores will be transformed to obtain a score ranging from 0 (worst experience) to 10 (best 
experience) for each item. The domain score will be the mean of the item scores included in the 
domain. Domain scores will be calculated only if at least half of the domain items were 
completed. 
The SIAQ questionnaire (date of publication 2011) will be completed by the subject as indicated 
in Table 8-1. 
 
8.5.1.1.2 Health-related quality of life (HRQoL) questionnaires 
The impact of psoriasis on various aspects of subject’s health-related quality of life (HRQoL) 
will be assessed by the DLQI. 
This questionnaire should be completed by subjects before they see the study physician 
(investigator or designee) who will perform the investigator assessments. 
It will be completed in the language the respondent is most familiar with. The subject should 
be given sufficient space and time to complete the questionnaires. The study coordinator should 
check it for completeness and encourage the subject to complete any missing responses. 
Completed questionnaires will be reviewed and examined by the investigator only after the 
clinical efficacy assessments (IGA mod 2011, PASI), for responses that may indicate potential 
AEs or SAEs. The investigator should review not only the responses to the questions in the 
questionnaires but also for any unsolicited comments written by the subject. If AEs or SAEs 
are confirmed then the investigator must record the events as per instructions given in Section 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 54
1 Protocol No. 
 
 
 
10 of the protocol. Investigator should not encourage the subject to change the responses 
reported in the completed questionnaires. 
The DLQI is a 10-item general dermatology disability index designed to assess health-related 
quality of life in adult subjects with skin diseases such as eczema, psoriasis, acne, and viral 
warts (Finlay and Khan 1994, Appendix 5). The measure is self-administered and includes 
domains of daily activities, leisure, personal relationships, symptoms and feelings, treatment, 
and work/school. The measure is widely used: it has been tested across 32 different skin 
conditions and is available in 55 languages. The recall period is the last week, and the instrument 
requires 1 to 2 minutes for completion. 
Each item has four response categories, ranging from 0 (not at all) to 3 (very much). "Not 
relevant" is also a valid  response and is scored as 0. The DLQI total score is a sum of the      
10 questions. Scores range from 0 to 30, and higher scores indicate greater health-related 
quality-of-life impairment. Additionally, each subscale of the DLQI may be analyzed separately. 
The purpose of the DLQI in this study is to investigate the effects of treatment of secukinumab 
with respect at Week 12, compared to placebo, and over time up to Week 52, compared to 
placebo. 
The DLQI questionnaire (version 2, date of publication 1994) will be completed by the subject 
as indicated in Table 8-1.

Study discontinuation and completion 
9.1 
Discontinuation 
9.1.1 
Discontinuation of study treatment 
Discontinuation of study treatment for a subject occurs when study drug is stopped earlier 
than the protocol planned duration, and can be initiated by either the subject or the 
investigator, subjects may voluntarily discontinue study treatment for any reason at any time. 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 56
1 Protocol No. 
 
 
 
The investigator must discontinue study treatment for a given subject if, on balance, he/she 
believes that continuation would negatively impact the risk/benefit of trial participation. 
Study treatment must be discontinued under the following circumstances: 
• Subject wish 
• Withdrawal of consent 
• Emergence of AEs that in the judgment of the investigator/qualified site staff, taking into 
account the subject’s overall status prevent the subject from continuing study treatment. 
• Any laboratory abnormalities that in the judgment of the investigator/qualified site staff, 
taking into consideration the subject’s overall status, prevent the subject from continuing 
participation in the study 
• Pregnancy (Section 10.1.4) 
• Ongoing use of prohibited treatment as shown in Table 6-1 
• Any situation in which study participation might result in a safety risk to the subject 
• Emergency unblinding 
If discontinuation of study treatment occurs, the investigator should make a reasonable effort 
to understand the primary reason for the subject’s premature discontinuation of study treatment 
and record this information on the appropriate eCRF page. 
Subjects who discontinue study treatment or who decide they do not wish to participate in the 
study further should NOT be considered withdrawn from the study UNLESS they withdraw 
their consent (see withdraw of informed consent section). Where possible, they should return 
for the assessments indicated in the assessment schedule. If they fail to return for these 
assessments for unknown reasons, every effort (eg, telephone, e-mail, letter) should be made to 
contact the subject/pre-designated contact as specified in the lost to follow-up section. This 
contact should preferably be done according to the study visit schedule. 
At the time of the study treatment discontinuation, 
• 
if it has been approximately 4 weeks post last dose of study treatment, then the 
assessments described in EOT1 or EOT2/EOS should be completed. 
• 
if it has not been approximately 4 weeks post last dose of study treatment, then the 
subject should be scheduled to return 4 weeks post last dose for their EOT1 
assessments or EOT2/EOS assessments. 
Assessments detailed in Table 8-1 should be completed and recorded in the eCRF. 
If the subject cannot or is unwilling to attend any visit(s), the site staff should maintain regular 
telephone contact with the subject, or with a person pre-designated by the subject. This 
telephone contact should preferably be done according to the study visit schedule. 
After study treatment discontinuation, at a minimum, in abbreviated visits, the following data 
should be collected at clinic visits or via telephone/email contact: 
• new / concomitant treatments 
• adverse events/Serious Adverse Events 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 57
1 Protocol No. 
 
 
 
The investigator must also contact the IRT when the subject completes EOT1 or EOT2/EOS 
visit to register the subject’s discontinuation from study treatment. 
If discontinuation occurs because treatment code has been broken, please refer to Emergency 
breaking of treatment code section. 
 
9.1.2 
Withdrawal of informed consent 
Subjects may voluntarily withdraw consent to participate in the study for any reason at any time. 
Withdrawal of consent occurs only when a subject: 
• 
Does not want to participate in the study anymore, and 
• 
Does not allow further collection of personal data 
In this situation, the investigator should make a reasonable effort (e.g. telephone, e-mail, letter) 
to understand the primary reason for the subject’s decision to withdraw his/her consent and 
record this information. 
Study treatment must be discontinued and no further assessments conducted, and the data that 
would have been collected at subsequent visits will be considered missing. 
Further attempts to contact the subject are not allowed unless safety findings require 
communicating or follow-up. 
All efforts should be made to complete the assessments prior to study withdrawal. A final 
evaluation at the time of the subject’s study withdrawal should be made as detailed in the 
assessment table. 
Novartis will continue to keep and use collected study information (including any data resulting 
from the analysis of a subject’s samples until their time of withdrawal) according to applicable 
law. 
For US and Japan: All biological samples not yet analyzed at the time of withdrawal may still 
be used for further testing/analysis in accordance with the terms of this protocol and of the 
informed consent form. 
For EU and RoW: All biological samples not yet analyzed at the time of withdrawal will no 
longer be used, unless permitted by applicable law. They will be stored according to applicable 
legal requirements 
 
9.1.3 
Lost to follow-up 
For subjects whose status is unclear because they fail to appear for study visits without stating 
an intention to discontinue or withdraw, the investigator must show "due diligence" by 
documenting in the source documents steps taken to contact the subject, eg, dates of telephone 
calls, registered letters, etc. A subject should not be considered as lost to follow-up until due 
diligence has been completed or until the end of the study. 
 
9.1.4 
Early study termination by the sponsor 
The study can be terminated by Novartis at any time for any reason. This may include reasons 
related to the benefit/ risk assessment of participating in the study, practical reasons (including 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 58
1 Protocol No. 
 
 
 
slow enrollment), or for regulatory or medical reasons. In taking the decision to terminate, 
Novartis will always consider the subject welfare and safety. Should early termination be 
necessary, subjects must be seen as soon as possible (provide instruction for contacting the 
subject, when the subject should stop taking drug, when the subject should come for a final 
visit) and treated as a prematurely withdrawn subject. 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 subject’s interests. The investigator or sponsor depending on the local 
regulation will be responsible for informing IRBs/IECs of the early termination of the trial. 
 
9.2 
Study completion and post-study treatment 
Study completion is defined as when the last subject finishes their Study Completion visit (Visit 
Week 52), and any repeat assessments associated with this visit have been documented and 
followed-up appropriately by the Investigator, or in the event of an early study termination 
decision, the date of that decision (eg, each subject will be required to complete the study in its 
entirety and thereafter no further study treatment will be made available to them). 
 
10 
Safety monitoring and reporting 
10.1 
Definition of adverse events and reporting requirements 
10.1.1 
Adverse events 
An adverse event (AE) is any untoward medical occurrence (eg, 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 
study until the end of study visit. Therefore, an AE may or may not be temporally or causally 
associated with the use of a medicinal (investigational) product. 
Novartis qualified medical personnel will be readily available to advise on trial related medical 
questions and problems. 
In addition, all reports of intentional misuse and abuse of the product are also considered an 
adverse event irrespective if a clinical event has occurred. The occurrence of adverse events 
must be sought by non-directive questioning of the subject at each visit during the study. 
Adverse events also may be detected when they are volunteered by the subject during or 
between visits or through physical examination findings, laboratory test findings, or other 
assessments. 
Abnormal laboratory values or test results constitute adverse events (Information about adverse 
drug reactions for the investigational drug can be found in the Investigator’s Brochure (IB)) 
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. 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 59
1 Protocol No. 
 
 
 
Clinically significant abnormal laboratory values or test results must 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 subject with 
underlying disease. Investigators have the responsibility for managing the safety of individual 
subject and identifying adverse events. Alert ranges for laboratory and other test abnormalities 
are included in Appendix 1. 
Adverse events must be recorded in the appropriate CRF capturing Adverse Events under the 
signs, symptoms or diagnosis associated with them, accompanied by the following information: 
1. 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 
2. its relationship to the study treatment (suspected: Yes / No) 
3. its duration (start and end dates) or if the event is ongoing an outcome of not 
recovered/not resolved must be reported. 
4. whether it constitutes a serious adverse event SAE – (See Section 10.1.2 for definition of 
SAE) and which seriousness criteria have been met. 
5. action taken regarding study treatment. 
All adverse events must be treated appropriately. Treatment may include one or more of 
the following: 
• Dose not changed

6. its outcome (not recovered/not resolved; recovered/resolved; recovered/resolved with 
sequelae; fatal; or unknown 
7. concomitant medication or non-drug therapy given 
8. subject hospitalized/subject’s hospitalization prolonged (see Section 10.1.2 for definition 
of SAE) 
Once an adverse event is detected, it must be followed until its resolution or until it is judged to 
be permanent, and assessment must 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. 
 
Worsening of psoriasis in this study is evaluated via the use of PASI, IGA mod 2011 and DLQI 
assessments and is not expected to be captured as an AE in the CRF capturing adverse events. 
Exceptions include cases when a) a new type of psoriasis is diagnosed eg, guttate psoriasis or 
b) the worsening of psoriasis is so severe that a qualitatively different status is reached. 
Information about common side effects already known about the investigational drug can be 
found in the Investigator’s Brochure (IB). This information will be included in the subject 
informed consent and should be discussed with the subject during the study as needed. Any new 

Novartis

information regarding the safety profile of the medicinal product that is identified between IB 
updates will be communicated as appropriate, for example, via an Investigator Notification or 
an Aggregate Safety Finding. New information might require an update to the informed consent 
and has then to be discussed with the subject. 
The investigator must also instruct each subject to report any new adverse event (beyond the 
protocol observation period) that the subject, or the subject’s personal physician, believes might 
reasonably be related to study treatment. This information must be recorded in the investigator’s 
source documents; however, if the AE meets the criteria of an SAE, it must be reported to 
Novartis. 
 
10.1.2 
Serious adverse events 
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 
• 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 subject’s 
general condition 
• is medically significant, eg, defined as an event that jeopardizes the subject 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. 
Life-threatening in the context of a SAE refers to a reaction in which the subject 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 it were more severe (please refer to 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 subject or might 
require intervention to prevent one of the other outcomes listed above. Examples of such events 
considered as “medically significant” 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 (please refer to Annex IV, ICH-E2D Guideline). 

Novartis

Any suspected transmission via a medicinal product of an infectious agent is also considered a 
serious adverse reaction. 
 
10.1.3 
SAE reporting 
To ensure subject safety, every SAE, regardless of causality, occurring after the subject has 
provided informed consent and until 12 weeks following the last administration of study 
treatment must be reported to Novartis safety within 24 hours of learning of its occurrence. Any 
SAEs experienced after 12 week period following the last administration of study treatment 
should only be reported to Novartis safety if the investigator suspects a causal relationship to 
study treatment. 
All SAEs reported up to the subject’s last visit will be reported in the appropriate eCRF. SAEs 
beyond the last visit will only be recorded in the Novartis Drug Safety and Epidemiology 
database. 
All follow-up information for the SAE including information on complications, progression of 
the initial SAE and recurrent episodes must be reported as follow-up to the original episode 
within 24 hours of the investigator receiving the follow-up information. An SAE occurring at a 
different time interval or otherwise considered completely unrelated to a previously reported 
one must 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 study treatment, 
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 subject 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 study 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 study 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.

10.1.4 
Pregnancy reporting 
Pregnancies 
To ensure subject safety, each pregnancy occurring after signing the informed consent 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 must be recorded on the Pharmacovigilance Pregnancy Form and reported by the 
investigator to the Novartis Chief Medical Office and Patient Safety (CMO & PS) Pregnancy 
follow-up should be recorded on the same form and should include an assessment of the 
possible relationship to the study treatment. 
Any SAE experienced during the pregnancy and unrelated to the pregnancy must be reported 
on a SAE form. 
 
10.1.5 
Reporting of study treatment errors including misuse/abuse 
Medication errors are unintentional errors in the prescribing, dispensing, administration or 
monitoring of a medicine while under the control of a healthcare professional, subject or 
consumer (EMA definition). 
Misuse refers to situations where the medicinal product is intentionally and inappropriately used 
not in accordance with the protocol. 
Abuse corresponds to the persistent or sporadic, intentional excessive use of a medicinal product, 
which is accompanied by harmful physical or psychological effects. 
Study treatment errors and uses outside of what is foreseen in the protocol will be recorded on 
the appropriate CRF irrespective of whether or not associated with an AE/SAE and reported to 
Safety only if associated with an SAE. Misuse or abuse will be collected and reported in the 
safety database irrespective of it being associated with an AE/SAE within 24 hours of 
Investigator’s awareness.

Data Collection and Database management 
11.1 
Data collection 
Designated investigator staff will enter the data required by the protocol into the Electronic 
Case Report Forms (eCRFs) using fully validated secure web-enabled software that conforms 
to US CFR 21 Part 11 requirements. 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 subject data for archiving at the 
investigational site. 
All data should be recorded, handled and stored in a way that allows its accurate reporting, 
interpretation and verification. 
 
11.2 
Database management and quality control 
Novartis personnel (or designated Contract Research Organization (CRO) will review the data 
entered by investigational staff for completeness and accuracy. Electronic data queries stating 
the nature of the problem and requesting clarification will be created for discrepancies and 
missing values and sent to the investigational site via the EDC system. Designated investigator 
site staff is required to respond promptly to queries and to make any necessary changes to the 
data. 
Concomitant medications entered into the database will be coded using the World Health 
Organization (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). 
ECGs will be analyzed centrally and results will be sent electronically to Novartis (or a 
designated CRO). Any clinically significant findings will be reported as (cardiovascular) 
medical history or AE depending upon timing of ECG assessment compared to screening. 
Subjects will fill in their PRO data in a site based tablet. The system will be supplied by a 
vendor, who will also manage the database. The database will be sent electronically to Novartis 
personnel (or designated CRO). 

Novartis 
Clinical Trial Protocol (Version 00)

Randomization codes and data about all study drug(s) dispensed to the subject 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 data 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. 
 
11.3 
Site monitoring 
Before study initiation, at a site initiation visit or at an investigator’s meeting, a Novartis/ 
representative will review the protocol and data capture requirements (i.e., eCRFs) 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 subject records, the accuracy of data capture / data 
entry, 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. Additionally, a central analytics organization may analyze data & identify risks & trends 
for site operational parameters, and provide reports to Novartis clinical teams to assist with trial 
oversight. 
The investigator must give the monitor access to all relevant source documents to confirm their 
consistency with the data capture and/or data entry. 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 
subjects will be disclosed. 
 
12 
Data analysis and statistical methods 
The analysis will be conducted on all subject data up to Week 16 for the week 16 interim 
analysis and on all data at the time of the trial ends for the final analysis. Any data analysis 
carried out independently by the investigator should be submitted to Novartis before publication 
or presentation. 
Treatment groups for analyses will include: 
Primary Week 12 analysis: 
• secukinumab 300 mg (2 mL AI)

be presented in contingency tables and will include absolute and relative frequencies. 
 
12.1 
Analysis sets 
The following analysis sets will be used in this study: 
Randomized set: The randomized set will be defined as all subjects who were randomized at 
baseline visit. Unless otherwise specified, subjects with missing informed consent form as well 
as mis-randomized subjects (mis-randomized in IRT) will be excluded from the randomized set. 
(Mis-randomized subjects are subjects who are screen-failures, but have been randomized by 
the investigator before eligibility was finally assessed, however have not been treated. If 
subjects were re-screened and successfully randomized, they will be included in the randomized 
set according to the treatment assigned in the last randomization.). 
Full analysis set (FAS): The FAS will be comprised of all subjects from the randomized set to 
whom study treatment has been assigned. Following the intent-to-treat principle, subjects will 
be analyzed according to the treatment assigned to at randomization. 
Safety set: The safety set includes all subjects who took at least one dose of study treatment 
during the treatment period. Subjects will be analyzed according to treatment received. 
 
12.2 
Subject demographics and other baseline characteristics 
Unless otherwise specified, for subject demographics and other baseline characteristics, 
analyses will be based on the randomized set. 
Demographics and baseline characteristics 
Summary statistics will be presented for continuous demographic and baseline characteristic 
variables for each treatment group and for all subjects in the randomized set. The number and 
percentage of subjects in each category will be presented for categorical variables for each 
treatment group and all subjects. 
Medical history 

Novartis 
Clinical Trial Protocol (Version 00)

Any condition entered as medical history or current medical conditions at baseline will be coded 
using the MedDRA dictionary. They will be summarized by system organ class and preferred 
term of the MedDRA dictionary. Summaries for cardiovascular and psoriasis specific medical 
history will be provided as well. 
 
12.3 
Treatments 
12.3.1 
Study treatment 
The analysis of study treatment data will be based on the safety set. 
The duration of exposure to study treatment will be summarized by treatment group. In addition, 
the number of subjects with exposure of at least certain thresholds (eg, any exposure, ≥ 1 week, 
≥ 2 weeks, ≥ 3 weeks, ≥ 4 weeks, ≥ 8 weeks, etc.) will be displayed. 
Duration of exposure of a treatment will be defined as the time from first dose of the treatment 
to the time of treatment switch (for subjects who switch from placebo to active treatment) or 
minimum of last dose of the treatment + 84 days and last visit date. 
 
12.3.2 
Prior and concomitant medication 
Prior and concomitant medications will be summarized by treatment group for the different 
periods in separate tables. 
Prior medications are defined as treatments taken and stopped prior to first dose of study 
treatment. Any medication given at least once between the day of first dose of randomized study 
treatment and the last day of study visit will be a concomitant medication, including those which 
were started pre-baseline and continued into the treatment period. 
Medications will be presented in alphabetical order, by Anatomical Therapeutic Classification 
(ATC) codes and grouped by anatomical main group. Tables will also show the overall number 
and percentage of subjects receiving at least one treatment of a particular ATC code and at least 
one treatment in a particular anatomical main group. 
Psoriasis specific pre-study treatments, number of pre-study systemic and biologic psoriasis 
therapies as well as reason for discontinuation will be presented. 
In addition, medical procedures and significant non-drug therapies as coded in MedDRA will 
be summarized. 
 
12.4 
Analysis of the primary variables 
Details of the testing strategy including primary endpoints are provided in Section 12.4.2. 
 
12.4.1 
Definition of primary endpoint(s) 
The co-primary efficacy variables are PASI 75 response at Week 12 and IGA mod 2011 0 or 1 
response at Week 12. The analysis of the co-primary variables will be based on the FAS. 

Novartis 
Clinical Trial Protocol (Version 00)

12.4.2 
Statistical model, hypothesis, and method of analysis 
The co-primary endpoints of this study are PASI 75 response and IGA mod 2011 0 or 1 response 
at Week 12. 
The statistical hypothesis is that secukinumab 300 mg (2 mL AI) is not superior to placebo with 
respect to the proportion of subjects with PASI 75 response and IGA mod 2011 0 or 1 response 
at Week 12. 
Let pj denote the proportion of PASI 75 responders at Week 12 for treatment group j and rj 
denote the proportion of IGA mod 2011 0 or 1 responders at Week 12 for treatment group j,    
j = 1, 0 where, 
• 0 corresponds to placebo 
• 1 corresponds to secukinumab 300 mg (2 mL AI) 
The following hypothesis will be tested: 
• H1: p1 − p0 ≤ 0 versus HA1: p1 − p0 > 0, 
• H2: r1 − r0 ≤ 0 versus HA2: r1 − r0 > 0 
In other words: 
H1: Secukinumab 300 mg (2 mL AI) is not superior to placebo with respect to PASI 75 
response at Week 12 
H2: Secukinumab 300 mg (2 mL AI) is not superior to placebo with respect to IGA mod 2011 
0 or 1 response at Week 12 
The primary analysis method will be the logistic regression with treatment group (secukinumab 
2mL AI vs Placebo); baseline bodyweight strata and baseline PASI score as explanatory 
variables. Odds ratios will be computed for comparisons of secukinumab dose regimen versus 
placebo utilizing the logistic regression model fitted. In case of response rates of 0% or of 100% 
in one of the treatment groups, Fisher’s exact test will be applied. Confidence intervals for risk 
difference will be derived based on the exact method. 
If logistic regression model does not converge the following steps will be performed: 
1. Run the PROC GENMOD procedure with EXACT statement; 
2. If convergence not reached, remove the covariates from the model one by one until 
convergence is reached; start with continuous covariates (baselines PASI score), followed 
by removing categorical covariates (i.e., weight stratum etc.,); 
3. If convergence not reached, perform Fisher’s exact test. 
In case of response rates of 0% or of 100% in one of the treatment groups, Fisher’s exact test 
will be applied. Confidence intervals for risk difference will be derived based on the exact 
method. 
The hypotheses H1 and H2 will both be tested at level 2.5% (one-sided), and significant results 
will only be achieved if both tests are rejected. If only one hypothesis is rejected and the other 
hypothesis is not rejected, superiority of secukinumab 300 mg (2 mL AI) has not been 
demonstrated.

12.4.3 
Handling of missing values/censoring/discontinuations 
The following imputation methods will apply to the missing data: 
• Response variables based on PASI score and IGA mod 2011 categories will be imputed 
with multiple imputations (MI) method as primary imputation method. MI is a simulation 
based approach where missing values are replaced by multiple Bayesian draws from the 
conditional distribution of missing data given the observed data and covariates, creating 
multiple completed data sets. These completed data sets can then be analyzed using standard 
methods. Within this analysis the PASI score or IGA mod 2011 categories will be imputed 
and response variables will be derived based on the imputed scores. In the multiple 
imputation analysis the response status will be imputed based on the individual treatment 
arm information. 
• Non-responder imputation will be used as sensitivity method: Missing values with respect 
to response variables based on PASI score and IGA mod 2011 categories will be imputed 
with non-response regardless to the reason for missing data (eg, premature study 
discontinuation, missed visit, administrative issues), exceptions will apply to the following: 
• If a subject dropped out of the study prior to last scheduled efficacy assessment and 
being responder consecutively at least for two preceding visits, the subject will be 
imputed as responder for the last scheduled visit. 
• If a subject who was responder at visit x-1 and visit x+1 but has missing data at visit 
x, then the subject will be imputed as responder for visit x as long as the distance 
between the scheduled visits x-1 and x is 4 weeks or less, or the distance between the 
scheduled visits x and x+1 is 4 weeks or less. Otherwise missing data will be imputed 
with non-response. 
 
12.4.4 
Sensitivity analyses 
Co-primary variables will be evaluated using the logistic regression as described in primary 
analysis method with non-responder imputations as sensitivity analyses. 
 
12.5 
Analysis of secondary endpoints 
The key secondary endpoint of this study is PASI 90 response at Week 12. 
Testing strategy 
As stated in Section 12.4.2, the hypotheses H1 and H2 will be included in co-primary testing 
procedure. Each hypotheses is tested at α = 2.5% (one-sided). The testing sequence will 
continue to key secondary endpoint PASI 90 at α = 2.5% (one-sided) only if both H1 and H2 
have been rejected at α (one-sided) such that a family-wise type-I-error of α (one-sided) is kept. 
H3: secukinumab 300 mg (2 mL AI) is not superior to placebo with respect to PASI 90 
response at Week 12 
PASI 90 response will be analyzed analogously to the primary endpoints at Week 12, i.e., the 
logistic regression model with treatment group, baseline bodyweight strata and baseline PASI 
score as exploratory variables. Odds ratios will be computed for comparisons of secukinumab 
versus placebo utilizing the logistic regression model fitted.

Summary statistics for PASI 50, PASI 75, PASI 90, PASI 100 and IGA mod 2011 0 or 1 
response by visit will be presented in contingency tables and will include absolute and relative 
frequencies. Confidence intervals for response rates will be derived as well based on the exact 
method. 
For PASI 50, PASI 75, PASI 90, PASI 100 and IGA mod 2011 0 or 1 response at each visit, 
comparisons between 2mL AI vs placebo and 2mL AI vs 1mL PFS x 2 will be conducted using 
logistic regression model with treatment group, body weight stratum, and baseline PASI as 
effects. 
Figures will be provided as well displaying estimates for responder rates by treatment including 
confidence intervals. 
 
PASI score over time 
Summary statistics will be provided for absolute PASI scores as well as for percent change from 
baseline by visit and treatment group. Figures will also be provided. 
 
IGA mod 2011 score over time 
Summary statistics for the IGA mod 2011 score over time will be presented by visit and by 
treatment group in contingency tables. Figures will also be provided. 
 
12.6.2 
Safety Endpoints 
All safety evaluations will be performed on the safety set. 
Analysis of adverse events will be based on treatment emergent events, which are defined as 
events started after the first dose of study treatment and within 84 days after the last study 
treatment, or events present prior to the first dose of study treatment but increased in severity 
based on preferred term within 84 days after the last study treatment. 
Other safety variables will be based on on-treatment events, which are defined as any events 
that happened after first dose of study treatment and on or before last dose + 84 days. 
 
Adverse events 
Treatment emergent AEs will be summarized for each treatment group by presenting the 
number and percentage of subjects with all/any AEs, AEs in each primary system organ class 
and each individual AE (preferred term). Summaries will also be presented for AEs by severity 
and for study treatment related AEs. If a subject reported more than one adverse event with the 
same preferred term, the adverse event with the highest severity will be presented. If a subject 
reported more than one adverse event within the same primary system organ class, the subject 

Novartis 
Clinical Trial Protocol (Version 00)

will be counted only once with the highest severity at the system organ class level, where 
applicable. 
Tabulated summaries will be presented for Treatment Period 1 and for the entire study 
(Treatment Period 1 combined with Treatment Period 2) 
Confidence intervals for relative frequencies will be derived as well according to the score 
method including continuity correction by Newcombe 1998. 
Separate summaries will be provided for death, serious adverse event, other significant adverse 
events leading to discontinuation and adverse events leading to study treatment discontinuation. 
A graphical display of relative frequencies within system organ classes will be presented. 
Exposure adjusted analyses in terms of incidence rate will be provided combining all the study 
periods. 
 
Laboratory data 
The summary of laboratory evaluations will be presented for three groups of laboratory tests 
(hematology and serum chemistry). Descriptive summary statistics for the change from baseline 
to each study visit will be presented. These descriptive summaries will be presented by test 
group, laboratory test and treatment group. Change from baseline will only be summarized for 
subjects with both baseline and post baseline. 
For each parameter, the maximum change from baseline within each study period will be 
analyzed analogously. 
Shift tables with respect to Common Toxicity Grade Criteria (CTC) and normal ranges will be 
provided. These summaries will be presented by laboratory test and treatment group. Shifts will 
be presented for most extreme values post-baseline. 
Incidence rates of notable abnormalities will be presented (Appendix 1). 
 
 
 
 
Vital signs 
Analysis of the vital sign measurements using summary statistics for the change from baseline 
for each post-baseline visit will be performed. These descriptive summaries will be presented 
by vital signs and treatment group. Change from baseline will only be summarized for subjects 
with both baseline and post-baseline values. 
All information collected will be listed by subject and abnormal values will be flagged 
(Appendix 1). 
 
12.6.3 
Health-related Quality of Life - Dermatology Life Quality Index (DLQI) 
Summaries will be based on the FAS and will be presented separately for each treatment group. 

Novartis 
Clinical Trial Protocol (Version 00)

For each of the seven scores the percentage change from baseline will be derived. Summary 
statistics will be provided for absolute values as well as for the percentage change by visit and 
treatment group. 
The absolute value and the percentage change from baseline of DLQI total score will be 
analyzed with the Van-Elteren test using type-II weights, for between-treatment comparison of 
the two secukinumab treatment groups versus placebo. The Van-Elteren test will be performed 
at each visit. Language of the questionnaire will be the stratum adjusted for in the Van-Elteren 
test. In addition, stratified Hodges-Lehmann estimates for the median as well as confidence 
intervals will be derived for the absolute values and percentage change to baseline for each 
treatment group as well as for treatment comparison between two secukinumab treatment 
groups versus placebo. 
It is understood that conclusions obtained from the confidence intervals of these estimates 
(mean or Hodges-Lehmann estimates for the median) will not be completely consistent with the 
testing results (Van-Elteren test) which constitute the key analysis for drawing conclusions. 
In addition, summary statistics will be provided for number of subjects achieving DLQI 0 or 1. 
Treatment groups will be compared by means of Fisher’s exact test. 
 
12.6.4 
Self-Injection Assessment Questionnaire (SIAQ) 
Summary statistics for the domain scores as well as item scores will be provided by visit and 
treatment group. 
Item and domain scores from the PRE module taken before the first self-injection at 
Randomization will be compared with the corresponding item and domain scores (Feeling about 
injections, Self-confidence domains and overall satisfaction of self-injection item) from the 
POST module taken after self-injections. Change from the PRE module to POST module in 
item and domain scores will be summarized by visit and treatment group.

Interim analyses 
A Week 16 analysis will be performed when all subjects have completed the Visit Week 16. 
Additional interim analyses may be performed to support health authority interactions as 
necessary. Trial modifications are not planned based on any interim analysis. 
At the end of study, a final analysis of all data collected up to last study visit (Week 52) will be 
performed when all subjects have completed the last study visit. 
 
12.8 
Sample size calculation 
A response rate of 8% for PASI 75 response and IGA mod 2011 0 or 1 response in the placebo 
group is expected, whereas a response rate of 62% for PASI 75 response and 55% for IGA mod 
2011 0 or 1 is the anticipated response in the secukinumab 300 mg (2 mL auto-injector s.c.) 
group. 
Placebo-response rates between 3% and 7% have been reported in (Papp et al 2005, Menter et 
al 2008, Leonardi et al 2008). 
 
12.8.1 
Primary endpoint(s) 
With respect to the co-primary endpoints (PASI 75 response and IGA mod 2011 0 or 1 response 
at Week 12), the type-I-error will be 2.5% one-sided for comparison. With 40 subjects per group 
and assuming a response rate of 8% for PASI 75 response and IGA mod 2011 0 or 1 response 
in the placebo group, the power to show a response rate of 62% for PASI 75 response and 55% 
for IGA mod 2011 0 or 1 response in the secukinumab 300 mg (2 mL auto-injector s.c.) group 
based on Fisher’s exact test (nQuery Advisor 7.01, two group Fisher’s-exact test of equal 
proportions) is above 99% for PASI 75 response and IGA mod 2011 0 or 1 response. 
 
12.8.2 
Secondary endpoint(s) 
The study should be sufficiently powered (above 90%) to show a response rate of 46% points 
in PASI 90 response if the placebo rate is assumed as 8%.

local regulations (including European Directive 2001/20/EC, US CFR 21), and with the ethical 
principles laid down in the Declaration of Helsinki. 
 
13.2 
Responsibilities of the investigator and IRB/IEC 
Before initiating a trial, the investigator/institution must obtain approval/favorable opinion from 
the Institutional Review Board/Independent Ethics Committee (IRB/ 
IEC) for the trial protocol, written informed consent form, consent form updates, subject 
recruitment procedures (eg, advertisements) and any other written information to be provided 
to subjects. 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. 
 
13.3 
Publication of study protocol and results 
The protocol will be registered in a publicly accessible database such as clinicaltrials.gov and 
as required in EudraCT. In addition, after study completion and finalization of the study report 
the results of this trial will be submitted for publication and posted in a publicly accessible 
database of clinical trial results, such as the Novartis clinical trial results website and all required 
Health Authority websites (eg, Clinicaltrials.gov, EudraCT etc.) 
For details on the Novartis publication policy including authorship criteria, please refer to the 
Novartis publication policy training materials that were provided to you at the trial investigator 
meetings. 
 
13.4 
Quality Control and Quality Assurance 
Novartis maintains a robust Quality Management System that includes all activities involved in 
quality assurance and quality control, to ensure compliance with written Standard Operating 
Procedures as well as applicable global/local GCP regulations and ICH Guidelines. 
Audits of investigator sites, vendors, and Novartis systems are performed by auditors, 
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 Standard Operating Procedures, and are performed according to written 
Novartis processes. 
 
14 
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 subjects should be 
administered as deemed necessary on a case by case basis. Under no circumstances including 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 74
1 Protocol No. 
 
 
 
incidental collection is an investigator allowed to collect additional data or conduct any 
additional procedures for any purpose involving any investigational drugs under the protocol, 
other than the purpose of the study. If despite this interdiction prohibition, data, information, 
observation would be incidentally collected, the investigator shall immediately disclose it to 
Novartis and not use it for any purpose other than the study, except for the appropriate 
monitoring on study participants. 
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. 
 
14.1 
Protocol amendments 
Any change or addition to the protocol can only be made in a written protocol amendment that 
must be approved by Novartis/sponsor health authorities where required, and the IRB/IEC prior 
to implementation. 
Only amendments that are required for subject safety 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 subject included in this 
study, even if this action represents a deviation from the protocol. In such cases, Novartis should 
be notified of this action and the IRB/IEC at the study site should be informed according to 
local regulations.

Appendix 6: Determination of Tuberculosis status 
Determination of tuberculosis (TB) status will be required before administration of study 
treatment and should be performed as defined by local guidelines. TB status must be determined 
by medical history, signs, symptoms and TB central lab testing. Any significant findings will 
be recorded in the relevant TB assessment eCRF and the Medical History eCRF, as necessary. 
A central lab testing will be performed to assess the TB status at screening for all subjects. This 
test will only be used to determine subject’s eligibility for the trial. The test will be used to 
screen the subject population for latent tuberculosis infection (Doherty et al 2008). 
This blood-based assay is specific for Mycobacterium tuberculosis and is not influenced by 
previous Bacillus Calmette-Guérin vaccination or by exposure to other Mycobacteria species. 
Furthermore, this test, in contrast to the purified protein derivative (PPD) skin test, is also 
insensitive to a booster effect since the subject is not exposed to the vaccine. The assay measures 
the production of interferon-gamma and presents it relative to a negative and a positive control 
sample (Manuel and Kumar 2008). The tuberculosis assay test will be supplied by the central 
laboratory. Details on the collection, shipment of samples and reporting of results by the central 
laboratory are provided to investigators in the study-specific laboratory manual. 
Positive or indeterminate tests must be recorded on the Tuberculosis assessment eCRF; the 
workflow of sample handling in case of positive or indeterminate test results is provided in 
Figure 16-1. 
a. If the test result is negative, the subject may be randomized. 
b. If the test result is positive, the investigator should perform a work-up for the test result as 
per local procedures. If a TB work-up was conducted prior to the screening of the subject, 
results of the work-up can be used to assess eligibility if the work-up was conducted within 
12 weeks prior to randomization. 
Subjects positive for latent TB per work-up may be randomized to the trial if sufficient 
treatment has been initiated according to local routine clinical practice and will be maintained 
for the prescribed duration. Subjects positive for active TB per work-up are not eligible for the 
study. Subjects negative for TB (no signs of latent or active TB) per work-up may be 
randomized to the trial. 
c. If the test result is indeterminate, the investigator may repeat the test once or may 
proceed directly to perform the work-up for the test result as per local procedures. This 
action is at the discretion of the investigator. If a TB work-up was conducted prior to the 
screening of the subject, results of the work-up can be used to assess eligibility if the work- 
up was conducted within 12 weeks prior to randomization. 
i. 
If the second test is negative, the subject may be randomized. 
ii. 
If the second test is positive or indeterminate, the investigator should perform workup 
as per local guidelines. Subject positive for latent TB per workup may be randomized 
to the trial if sufficient treatment has been initiated according to local routine clinical 
practice and will be maintained for the prescribed duration. The subject will not be 

Novartis 
Clinical Trial Protocol (Version 00) 
Confidential 
Page 90
1 Protocol No. 
 
 
 
eligible for randomization if“active tuberculosis is present”or“latent tuberculosis 
is present” and is untreated per local guidelines. . 
iii. 
Subjects negative for TB per workup (no signs of latent or active TB) may be 
randomized to the trial if the workup was conducted 12 within weeks prior to 
randomization. . 
If eligibility is being assessed with only 1 test result and a TB work-up (i.e., no second TB test 
will be performed), the TB test to assess eligibility must have been done via the central 
laboratory for the study within the Screening Period (within 4 weeks prior to randomization) 
and TB work-up will only be considered if it was completed within 12 weeks prior to 
randomization.
