Investigation type 
Drug  
Study type 
Interventional  
Purpose and rationale 
The primary purpose of this study is to assess efficacy, safety and 
tolerability of 2 mL pre-filled syringe of 300 mg secukinumab. Results of 
this study will support the registration of secukinumab 300 mg in 2 mL pre-
filled syringes.  
This 52-weeks, double-blind, randomized, parallel-group, and placebo-
controlled study is using the recommended dose of 300 mg secukinumab 
which has been approved in Japan, USA, EU, Switzerland and other 
countries for the treatment of moderate to severe psoriasis in adults. 
Primary Objective  
The primary objective is to demonstrate the efficacy of secukinumab 
300 mg when administered as 2 mL pre-filled syringes in subjects with 
plaque-type psoriasis with respect to both PASI 75 and IGA mod 2011 0 
or 1 response (co-primary endpoint) at Week 12, compared to placebo. 
Secondary Objectives 
Key Secondary Objectives 
• 
To demonstrate the efficacy of secukinumab 300 mg when 
administered as 2 mL pre-filled syringes in subjects with plaque-type 
psoriasis with respect to PASI 90 and PASI 100 at Week 12, compared 
to placebo. 
• 
To demonstrate the efficacy of secukinumab 300 mg when 
administered as two 1 mL pre-filled syringes in subjects with plaque-
type psoriasis with respect to PASI 100 at Week 12, compared to 
placebo. 
Other Secondary Objectives 
• 
To assess the efficacy of secukinumab 300 mg 2 mL pre-filled syringes 
on moderate to severe 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 pre-filled syringes as assessed by vital signs, clinical 
laboratory variables, and adverse events (AEs) monitoring, compared 
to placebo.  

Novartis

Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
• 
To assess the subject usability (ability to follow instructions for use and 
potential use-related hazards) and satisfaction with the secukinumab 
2 mL pre-filled syringes utilizing a self-administered Self-Injection 
Assessment Questionnaire (SIAQ) and investigator / site staff 
observation of secukinumab 300 mg 2 mL pre-filled syringe 
administration.  
• 
To assess the effects of secukinumab 300 mg 2 mL pre-filled syringes 
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-weeks multicenter, randomized, double-blind, placebo-
controlled, parallel-group trial in approximately 210 subjects with moderate 
to severe plaque-type psoriasis.  
The study consists of 4 epochs: Screening (of at least 1 week and up to 4 
weeks), Treatment Epoch I (of 12 weeks), Treatment Epoch II (of 40 
weeks) and Follow-up. The treatment-free phase of 8-weeks should only 
be completed in case subjects discontinue early.  
Subjects will be randomized using a 1:1:1 ratio to the following groups: 
secukinumab 300 mg regimen group (2 mL), secukinumab 300 mg 
regimen group (1 mL) or to placebo. After administration of the Week 12 
dose, all subjects in the placebo group will continue the treatment based 
on their PASI 90 response status at Week 12. PASI 90 non-responders will 
receive in a 1:1 ratio either secukinumab 300 mg (2 mL) or secukinumab 
300 mg (1 mL). PASI 90 responders will continue to receive placebo. All 
treatment groups have additional matching placebos. 
Population 
Approximately 210 subjects with moderate to severe plaque psoriasis will 
be randomized in approximately 57 centers worldwide. Approximately 250 
subjects are expected to be screened to provide the number of randomized 
subjects. It is also expected to randomize approximately 20% of subjects 
who also suffer from psoriatic arthritis. 
Key Inclusion criteria 
Subjects eligible for inclusion in this study must fulfill all of the following 
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

type-I-error of 2.5% (one-sided): 
• 
H1: secukinumab 300 mg (2 mL s.c. injection) is not superior to 
placebo with respect to PASI 75 response at Week 12 
• 
H2: secukinumab 300 mg (2 mL s.c. injection) is not superior to 
placebo with respect to IGA mod 2011 0 or 1 response at Week 12 
• 
H3: secukinumab 300 mg (2 mL s.c. injection) is not superior to 
placebo with respect to PASI 90 response at Week 12 
• 
H4: secukinumab 300 mg (2 mL s.c. injection) is not superior to 
placebo with respect to PASI 100 response at Week 12 
• 
H5: secukinumab 300 mg (two 1 mL s.c. injections of 150 mg 
secukinumab) is not superior to placebo with respect to PASI 100 
response at Week 12 
The testing sequence will continue to H3 at α (one-sided) only if both H1 
and H2 have been rejected at α (one-sided). Similarly, the testing 
sequence will continue to H4 at α (one-sided) only if H3 testing has been 
rejected. In case, H4 has been rejected at α (one-sided), the 
corresponding alpha (α) will be passed to the next hypothesis 
corresponding to H5.

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 et al 2003, 
Griffiths et al 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 
health-care 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 (e.g. 
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 (e.g. 
not achieving a decrease in Psoriasis Area and Severity Index (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-IL 12/23 class of biological drugs provided clinicians with another 
treatment option (Kerdel et al 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 are currently being investigated in 
Phase III studies for the treatment of a range of immune mediated inflammatory diseases (Puig 
2014). 
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 
and neutralizes the bioactivity of this cytokine. IL-17A is the central cytokine of a newly defined 

Novartis

Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
subset of inflammatory T cells, the Th17 cells which, in several animal models, are pivotal in 
multiple autoimmune and inflammatory processes. IL-17A is mainly produced by memory 
effector CD4+ and CD8+ T lymphocytes 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. IL17A). Secukinumab (Cosentyx®) with a recommended 
dose of 300 mg was approved in 2014 in Japan, and 2015 in USA, EU, Switzerland, and 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. 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 syringe containing 300 mg of secukinumab.  
As of 25 June 2015, approximately 12,000 subjects have been enrolled in studies with 
secukinumab, of which 9,600 have 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 2015, there are 79 completed and multiple ongoing trials 
conducted with secukinumab in indications including psoriasis, psoriatic arthritis, 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 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, Pharmacokinetic (PK) parameters and local 
tolerability of a 2 mL pre-filled syringe of 300 mg secukinumab. 
1.2 
Purpose  
The primary purpose of this study is to assess efficacy, safety and tolerability of 2 mL pre-filled 
syringe of 300 mg secukinumab. Results of this study will support the registration of 
secukinumab 300 mg in 2 mL pre-filled syringes.

Investigational plan 
3.1 
Study design 
This is a 52-week multicenter, randomized, double-blind, placebo-controlled, parallel-group 
trial in approximately 210 subjects with moderate to severe plaque-type psoriasis.  
The study consists of 4 epochs: Screening (of at least 1 week and up to 4 weeks), Treatment 
Epoch I (of 12 weeks), Treatment Epoch II (of 40 weeks) and Follow-up. The treatment-free 
phase of 8-week should only be completed in case of early discontinuations.  
Safety, efficacy and pharmacokinetic peak and trough level measurements of secukinumab will 
be performed according to the pre-defined visit schedule as described in Figure 3-1 and in Table 
6-1.

Treatment Epoch I (Randomization to Week 12 pre-dose) 
The Treatment Epoch I is defined as Randomization through Visit Week 12 (prior to Week 12 
dose). At the start of the Treatment Epoch I, eligible subjects will be randomized at a 1:1:1 ratio 
to one of three treatment groups: 
• Secukinumab 300 mg regimen group (2 mL syringe): one 2 mL secukinumab 300 mg 
plus two 1 mL matching placebo secukinumab s.c. injections once weekly for four weeks 
(at Randomization, Weeks 1, 2, and 3), followed by dosing every four weeks, starting at 
Week 4 up to Week 12.  
• Secukinumab 300 mg regimen group (1 mL syringe): two 1 mL secukinumab 150 mg 
plus one 2 mL matching placebo secukinumab s.c. injection once weekly for four weeks (at 
Randomization, Weeks 1, 2, and 3), followed by dosing every four weeks, starting at 
Week 4 up to Week 12.  
• Placebo group: placebo secukinumab (two 1 mL s.c. injections and one 2 mL injection per 
dose) once per week for four weeks (at Randomization, Visits Week 1, 2, and 3), followed 
by dosing every four weeks starting at Week 4 up to Week 12.  
For subjects who discontinue the study treatment prematurely for any reason before the End of 
the Treatment Epoch I, the End of Treatment Epoch I (EOTEI) Week 12 visit should be 
performed approximately four weeks after their last dose of study treatment (secukinumab or 
placebo). Thereafter, subjects should enter the treatment-free 8-week Follow-up Epoch.  
Subjects will be visiting the study site at Randomization and Visits Week 1, 2, 3, 4, 8 and 12. 
Treatment Epoch II (Week 12 post-dose to Week 52)  
The Treatment Epoch II is defined as Week 12 through Week 52.  
Prior to receiving the Week 12 dose, all subjects from the placebo group will be assigned to 
the following treatment groups based on their PASI 90 response status at Week 12. 
• PASI 90 non-responders from the placebo group will receive at a ratio 1:1 either one 
2 mL 300 mg secukinumab plus two 1 mL matching placebo OR two 1 mL of 150 mg 
secukinumab s.c plus one 2 mL matching placebo injections at Weeks 12, 13, 14, and 15, 
thereafter every four weeks starting at Week 16 and up to Week 48.  
• PASI 90 responders will receive their placebo injections at Weeks 12, 13, 14, 15, and 
then every four weeks starting at Week 16 up to Week 48.  
Subjects from the two active groups (who were on secukinumab since randomization) will 
receive placebo (one 2 mL and two 1 mL s.c. injections) at Weeks 13, 14 and 15 and continue 
with the treatment assigned at randomization every four weeks starting at Week 16 and up to 
Week 48. End of Treatment Epoch II (EOTEII) is at Week 52 and is also the end of the study. 
Home administrations (H) of study drug are scheduled at Weeks 20, 24, 32, 36, 44 and 48.  
End of Treatment Epoch II (EOTEII) is at week 52 and is also the formal end of the study. At 
this visit, the site should call IRT after performing the scheduled study assessments to record 
the completion by subject(s).

For subjects who discontinue study treatment prematurely for any reason before the end of the 
Treatment Epoch II, the End of Treatment Epoch II (EOTEII) Week 52 visit should be 
performed approximately four weeks after their last dose of study treatment (secukinumab or 
placebo). Thereafter, the subject should enter the treatment-free 8-week Follow-up Epoch.  
Follow-up Epoch (8 weeks) 
Only subjects who prematurely discontinue the treatment in Treatment Periods I or II for any 
reason will enter the treatment-free Follow-up Epoch to complete Visits F4 and F8 (as shown 
in Table 6-1). 
3.2 
Rationale for study design 
The intent of this study is to assess a 2 mL pre-filled syringe form for the administration of 
300 mg of secukinumab instead of two injections of 1 mL of 150 mg each, to psoriasis subjects 
that are treated with secukinumab at the recommended dose.  
This 52-weeks, double-blind, randomized, parallel-group, and placebo-controlled study is using 
the recommended dose of 300 mg secukinumab which has been approved in Japan, USA, EU, 
Switzerland and other countries for the treatment of moderate to severe psoriasis in adults.  
The study is in accordance with health authority guidelines and feedback on the clinical 
development program for the 2 mL pre-filled syringe, including the United States Food and 
Drug Administration (FDA) and EU agencies. 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 2012). 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 CAIN457A2323. 
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 (pre-filled syringe in 
CAIN457A2308, and auto-injector in CAIN457A2309; Blauvelt 2014, Paul 2015). 
Overall, this study will assess the efficacy, PK, safety 
 and 
tolerability of secukinumab and includes a human factor analysis (including usability [ability 
to follow instruction for use and potential use-related hazards] and satisfaction) of secukinumab 
in 2 mL pre-filled syringes when used both, short-term (up to 12 weeks) and long-term (up to 
52 weeks). This data will support the registration of secukinumab 300 mg in 2 mL pre-filled 
syringes. 
3.3 
Rationale for dose/regimen, route of administration and duration 
of treatment 
The placebo-controlled study design was chosen to demonstrate the efficacy of 300 mg 
secukinumab administered as 2 mL pre-filled syringe in adult subjects suffering from moderate 

Novartis 
Confidential 
Page 20 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
to severe psoriasis compared to placebo. The selected dose regimen for this study with an initial 
weekly schedule up to 4 weeks followed by an 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 PK and safety profile with the secukinumab 2 mL 
300 mg pre-filled syringe. 
3.4 
Rationale for choice of comparator 
Due to the nature of psoriasis and the outcome measures for the primary and the secondary 
endpoints used (PASI 50, 75, 90 and 100 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 the indication of plaque-type psoriasis. Subjects from the placebo group that will 
not achieve PASI 90 after Week 12 will receive secukinumab.  
3.6 
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.  
In total 4,546 patients with moderate to severe plaque psoriasis were included in studies in the 
registration program. This included 3,430 patients 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 immunogenicity 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 

Novartis 
Confidential 
Page 21 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
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. 
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 patients with a simple easy to use 
single-injection device for the treatment of psoriasis.  
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 pre-filled syringe, and therefore 
it is appropriate to initiate study CAIN457A2323 for registration purposes.

Population 
Approximately 210 subjects with moderate to severe plaque psoriasis will be randomized in 
approximately 57 centers worldwide. Approximately 250 subjects are expected to be screened 
to provide the number of randomized subjects. It is also expected to randomize approximately 
20% of subjects who also suffer from psoriatic arthritis. Drop-outs after randomization will not 
be replaced.

Periodic abstinence (e.g., calendar, ovulation, sympto-thermal, post-ovulation methods) and 
withdrawal are not acceptable methods of contraception. 
• Female sterilization (have had surgical bilateral oophorectomy (with or without 
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). 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, injected or implanted hormonal methods of contraception or other forms of 
hormonal contraception that have comparable efficacy (failure rate < 1%), e.g. hormone 
vaginal ring or transdermal hormone contraception or placement of an intrauterine device 
(IUD) or intrauterine system (IUS). 
• 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. 
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 (e.g. age 
appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy 
(with or without 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 
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 (systolic ≥ 160 mmHg and/or diastolic ≥ 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 
infection as defined by a positive QuantiFERON TB-Gold test (QFT) at Screening. 
Subjects with a positive or indeterminate QFT test may participate in the study if full 
tuberculosis work up (according to local practice/guidelines) was completed within 12 
weeks prior to randomization and 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 guidelines prior to randomization. 
12.  Past medical history record or current infection with HIV, 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 (e.g., because of poor 
tolerability or lack of access to veins).  
15.  History or evidence of ongoing alcohol or drug abuse, within the last six months before 
Randomization. 
16.  History of hypersensitivity to any of study drug constituent.

 Study treatment 
5.1.1 
Investigational and control drugs 
Novartis will supply the following study drugs with the same liquid formulation:  
Investigational treatment: 
• Secukinumab 300 mg, provided in a 2 mL pre-filled syringe  
Control treatment: 
• Secukinumab 300 mg, provided as two injections of 1 mL pre-filled syringe (each 1 mL 
syringe containing 150 mg scekinumab)  

Novartis 
Confidential 
Page 25 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
• Secukinumab matching placebo, provided in a 1 mL or 2 mL pre-filled syringe 
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. Subjects 
will be initially instructed about injections by site staff. They will receive 
explanations/instructions on how to self-inject the pre-filled syringe thereafter.  
The removable cap of the secukinumab pre-filled syringe 1mL form only contains a derivative 
of natural rubber latex (note: this is not applicable to the 2 mL syringe). Although no natural 
rubber latex is detected in the cap, the safe use of the secukinumab 1 mL pre-filled syringe in 
latex-sensitive individuals has not been studied. 
5.1.2 
Additional treatment 
No additional treatment beyond investigational drug and control drug are included in this trial. 
5.2 
Treatment arms 
Subjects will be assigned to one of the following 3 treatment arms with 70 subjects per arm. 
Subjects will self-administer all secukinumab and placebo doses at study sites or at home (Table 
6-1). There will always be three injections. 
Subjects will be randomized using a 1:1:1 ratio into one of the treatment groups: 
• Secukinumab 300 mg regimen group (2 mL): one 2 mL secukinumab 300 mg plus two 
1 mL matching placebo secukinumab s.c. injections once weekly for four weeks (at 
Randomization, Weeks 1, 2, and 3), followed by dosing every four weeks, starting at 
Week 4 up to Week 48. Subjects will receive three placebo injections at Weeks 13, 14 and 
15. 
• Secukinumab 300 mg regimen group (2 x 1 mL): two 1 mL secukinumab 150 mg plus 
one 2 mL matching placebo secukinumab s.c. injection once weekly for four weeks (at 
Randomization, Weeks 1, 2, and 3), followed by dosing every four weeks, starting at 
Week 4 up to Week 48. Subjects will receive three placebo injections at Weeks 13, 14 and 
15. 
• Placebo group: placebo secukinumab (two 1 mL s.c. injections and one 2 mL injection per 
dose) once per week for four weeks (at Randomization, Visits Week 1, 2, and 3), followed 
by dosing every four weeks starting at Week 4 up to Week 12.  
After administration of the Week 12 dose, all subjects in the placebo group will continue the 
treatment based on their PASI 90 response status at Week 12: 
• PASI 90 non-responders will receive 1:1 ratio either one 2 mL 300 mg secukinumab s.c. 
plus two 1 mL matching placebo OR two 1 mL 150 mg secukinumab s.c. injections plus 
one 2 mL matching placebo at Weeks 12, 13, 14, 15, and then every four weeks starting at 
Week 16 up to Week 48.  
• PASI 90 responders will continue on placebo (one 2 mL plus two 1 mL s.c. injections) and 
will receive their placebo injections at Weeks 12, 13, 14, 15, and then every four weeks 
starting at Week 16 up to Week 48.

5.3 
Treatment assignment and randomization  
At Baseline/Randomization visit, all eligible subjects will be randomized via Interactive 
Response Technology (IRT) to one of the treatment arms. 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 a 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 caller.  
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 
Drug Supply Management 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 will be entered in the Screening Epoch Disposition 
electronic Case Report Form (eCRF).  
Randomization will not be stratified. 
The randomization scheme for subjects will be reviewed and approved by a member of the 
Randomization Group.  
5.4 
Treatment blinding  
Subjects, investigators/site personnel and Novartis clinical team reviewing data will remain 
blind to the identity of the treatment from the time of randomization, 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. (2) the identity of the treatments 
will be concealed by the use of investigational treatment that are all identical in packaging, 
labeling, appearance, and schedule of administration. 
Unblinding will only occur in the case of subject emergencies (Section 5.5.9), at the time of the 
endpoint analysis (Section 3.5) as described below. 
The blind will be kept until the final/end of study database lock. 
The randomization codes associated with subjects from whom PK samples are taken will be 
disclosed to PK analysts who will keep PK results confidential until 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 5.5.9).

Treating the subject  
5.5.1 
Subject numbering 
Each subject is uniquely identified by a Subject Number which is composed by the site number 
assigned by Novartis and a sequential number assigned by the investigator. Once assigned to a 
subject, the Subject Number will not be re-used.  
Upon signing the Informed Consent Form (ICF), the subject is assigned the next sequential 
number by the investigator. The investigator or his/her staff will contact the IRT and provide 
the requested identifying information for the subject to register them into the IRT. The site must 
select the eCRF book with a matching Subject Number from the EDC system to enter data.  
5.5.2 
Dispensing the study drug 
Each study site will be supplied with study drug in packaging of identical appearance. 
The study drug packaging has a 2-part label. A unique medication number is printed on each 
part of this label which corresponds to one of the 2 treatment arms.  Investigator staff will 
identify the study drug package(s) to dispense to the subject by contacting the IRT and obtaining 
the medication number(s). Immediately before dispensing the package to the subject, 
investigator staff will detach the outer part of the label from the packaging and affix it to the 
source document (Drug Label Form) for that subject’s unique subject number.  
5.5.3 
Handling of study and additional treatment 
5.5.3.1 
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 designees 
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 Country Pharma 
Organization (CPO) Quality Assurance. 
Medication labels will be in the local language and comply with the legal requirements of each 
country. They will include storage conditions for the 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.  
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 as instructed.  
5.5.3.2 
Handling of additional treatment 
Not applicable.

5.5.4 
Instructions for prescribing and taking study treatment 
The first study treatment administration will occur at the Randomization Visit after the 
inclusion/exclusion criteria have been confirmed and all study scheduled assessments have been 
performed (except the SIAQ POST module to be completed 20-40 minutes after dosing of all 
three injections). All other study assessments, including blood withdrawal and completion of 
Patient Reported Outcomes (PROs), i.e. DLQI, 
 except the SIAQ POST module as 
applicable, should be completed prior to the self- injection of study treatment. The flow of work 
and the consecutive steps of assessments including Clinical Outcome Assessments (COA) are 
given in Section 6. 
All doses of study treatment (secukinumab and/or placebo) will be self-administered by the 
subject either at the study site after the study assessments for the visits have been completed or 
at home.  
The first use at Randomization and the 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 through the site staff by walking them through the Instructions For Use (IFU) on how 
to self-inject via the pre-filled syringe (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). During the first two self-injections 
at the respective visits (Randomization and Week 1) site staff will observe and complete the 
self-injection assessment checklist for the 2 mL syringe (Table 6-4) at the first of the two 
injections at each visit. The possible hazard assessment check list (Table 6-5) will be assessed 
at each of the applicable visits. 
Home administrations (H) should be done at pre-defined visits (Table 6-1). Home 
administration can be performed by subject or 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 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 
The study treatment solution must be injected in non-affected areas of the skin. 
Administration of study treatment may vary on the body regions, i.e. changing the injection site 
whilst separating the 2 mL syringe and the two 1 mL syringes.  
Pre-filled syringes should be kept at 2 to 8°C (36°F and 46°F),  never be frozen,  and should 
be protected from light. Prior to administration, the boxes containing the pre-filled syringes 
should be allowed to adapt to room temperature unopened for about 20 minutes before 

Novartis 
Confidential 
Page 29 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
administration. Used syringes should be disposed immediately after  use  in  a  sharps  container 
or according to the regulatory needs of the respective countries. 
5.5.5 
Permitted dose adjustments and interruptions of study treatment  
Investigational or other treatment dose adjustments and/or interruptions are not permitted. 
5.5.6 
Rescue medication 
Use of rescue medication is not permitted in this study.  
5.5.7 
Concomitant medication  
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.  
Any treatment known to worsen psoriasis (e.g. beta-blockers, calcium channel blockers, 
lithium) should be stable at least 4 weeks before randomization. 
5.5.8 
Prohibited medication 
Use of any treatments displayed in Table 5-1 that could confound the efficacy of the 
investigational drug is NOT allowed during the study for any indication.  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 Concomitant Medications eCRF and should be avoided during the 12 hours 
preceding a scheduled visit. Use of any other non-medicated interventions should be recorded 
in the eCRF.  
A mild to moderate potency topical corticosteroid (TCS) will be allowed for the treatment of 
the face, scalp, and anogenital area during the Screening Epoch.  These TCS should be stopped 
at least the day before the Randomization Visit.  
The investigator should instruct the subject to notify the study site about any/all new/additional 
treatments after starting the study drug administration. Prior to starting the study, all prohibited 
treatments should be washed out as shown in Table 5-1 below. At the discretion of the 
investigator,  if any use of a prohibited treatment presents  an undue  safety  risk  for  the  subject,  
the  study treatment  should  be discontinued. If a live vaccination has to be administered, the 
study treatment should be discontinued.

c Oral, i.v., i.m., s.c., intra-articular, peri-articular. Exception: inhalative corticosteroids (CS) with only a topical effect (e.g., to treat 
asthma) are not considered “systemic immunomodulating treatments” and are therefore acceptable as co-medication.  
d There is no restriction on the use of anti-histamines and on the use of corticosteroids in the eye, nose or the ear 
e Mild to moderate topical corticosteroids (TCS) are allowed only during the Screening Epoch if used only on the face, scalp 
and/or anogenital area and should be stopped the day before the Randomization visit. 
f Topical corticosteroids (mild to moderate) and other topical treatments will be allowed during Treatment Epoch II ONLY if (all 
must apply):

medication was started after the Week 12 visit was completed; 
- 
medication was used for 14 consecutive calendar days or less; 
- 
medication was used for an indication other than psoriasis and not on the area affected with psoriasis. 
*** Inactivated virus vaccinations are allowed 
 
Exposure to light 
Exposure to ultraviolet (UV) light (including sunbathing and/or use of UV tanning devices) 
should be limited to avoid possible effect on psoriasis. 
5.5.9 
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 

Novartis 
Confidential 
Page 31 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
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 an e-mail with an onscreen display of the medication confirming 
this information. The system will 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 and applicable) 
• Subject number 
In addition, oral and written information to the subject must be provided on how to contact 
his/her backup in cases of emergency, or when he/she is unavailable, to ensure that un-blinding 
can be performed at any time.  
Study treatment must be discontinued after emergency unblinding. 
5.6 
Study completion and discontinuation  
5.6.1 
Study completion and post-study treatment 
A subject will be considered to have completed the study when the subject has completed the 
last visit planned in the protocol (Visit Week 52 or Visit F8). 
The investigator must provide follow-up medical care for all subjects who are pre-maturely 
withdrawn from the study, or must refer them for appropriate ongoing care. 
5.6.2 
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. 
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 the following AEs: 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. 

Novartis 
Confidential 
Page 32 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
• 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 
study treatment. 
• Pregnancy (Section 6.5.6 and Section 7.6) 
• Ongoing use of prohibited treatment as shown in Table 5-1 
• Any situation in which study participation might result in a safety risk to the subject 
• Emergency unblinding 
If discontinuation of study treatment occurs for any reason, the subject should NOT be 
considered   withdrawn   from   the   study.   The   subject   should   return   to   the   site  after 
discontinuation of study drug, for an End of Treatment visit and Follow-up visits (F4 and F8). 
Assessments detailed in the “End of Treatment visit” and Follow-up visits (F4 and F8) in 
Table 6-1 should be completed and recorded in the eCRF. The investigator must determine the 
primary reason for the subject’s premature discontinuation of study treatment and record this 
information on the eCRF. 
At the time of the study treatment discontinuation visit, if it has been approximately 4 weeks 
post last dose of study treatment then the assessments described in EOTEI OR EOTEII should 
be completed at this visit. 
If it has not been approximately 4 weeks post last dose of study treatment at the time of the 
study treatment discontinuation visit, then the subject should be scheduled to return 4 weeks 
post last dose for their EOTEI assessments OR EOTEII assessments. 
The investigator/qualified site staff must contact the IRT when the subject completes the EOT 
Visit Week 12/EOTEI OR Week 52/EOTEII assessments to register the subject’s early 
completion of the study due to study treatment discontinuation.  
Further, the subject should also return for the final Follow-up visits, F4 (8 weeks after last study 
treatment) and F8 (12 weeks after last study treatment) as shown in Table 6-1. 
After study treatment discontinuation, at a minimum, the following data should be collected at 
site visits or via telephone visits: 
• New/concomitant treatments 
• Adverse events/serious adverse events 
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. 
The investigator must also contact the IRT to register the subject’s discontinuation from study 
treatment. 
If study drug discontinuation occurs because treatment code has been broken, please refer to 
Section 5.5.9. 
5.6.2.1 
Discontinuation from a treatment-free period 
If premature withdrawal occurs for any reason in the treatment-free period (within the four 
weeks after last dose or in the 8-week Follow-up Epoch), the investigator must make every 

Novartis 
Confidential 
Page 33 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
effort to determine the primary reason for a subject’s premature withdrawal from the study 
and record this information on the applicable end of study eCRF (i.e. F8). 
In Section 6 assessments for subjects who discontinue from the Follow-up Epoch are shown.  
5.6.3 
Withdrawal of informed consent 
Subjects may voluntarily withdraw consent to participate in the study for any reason at any 
time. Withdrawal of consent from the study is defined as when a subject: 
• Does not want to participate in the study anymore 
and 
• Does not want any further visits or assessments 
and 
• Does not want any further study related contacts 
and 
• Does not allow analysis of already obtained biologic material  
In this situation, the investigator must make every effort (e.g. telephone, e-mail, letter) to 
determine 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  
Table 6-1. 
5.6.4 
Loss 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 should show "due diligence" by 
documenting in the source documents steps taken to contact the subject, e.g. dates of telephone 
calls, registered letters, etc. A subject cannot be considered as lost to follow-up until the time 
point of his/her scheduled end of study visit has passed. 
5.6.5 
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, or for 
regulatory or medical reasons (including slow enrollment). Should this be necessary, the subject 
must be seen as soon as possible 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 will

Visit schedule and assessments 
Table 6-1 lists assessments that are recorded in the clinical database. Assessments that are 
source documentation only will not be entered into the eCRF. Data reflecting to which 
inclusion/exclusion criteria are not met are captured on the Inclusion/Exclusion eCRF.  
Subjects should be seen for all visits on the designated day or as closely as possible to the original 
planned visit schedule (Table 6-1). Every effort should be made to respect the timeframe for all 
visits and particularly when PK samples are collected.  
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 re-screens for the study, then the subject must sign a new ICF and be issued a new 
subject number prior to any screening assessment being conducted for the subject under the 
new screening subject number. For all subjects, the investigator/qualified site staff will record 
if the subject was re-screened on the re-screening 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 Informed Consent eCRF 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 and chest x-ray, if applicable, if performed 
not more than 12 weeks before randomization. 
For subjects who discontinue study treatment prematurely before the end of the treatment epoch 
for any reason other than withdrawal of informed consent or loss to follow-up procedures 
as described in Section 5.6 should be followed. 
During Treatment Epochs I and II, subjects may be seen at an unscheduled visit, e.g. 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 6-1 is as follows (may vary depending 
on different type of visits): 
Subjects 
• Subjects should usually complete the subject-reported outcome (PROs/ePROs) assessments 
(i.e. DLQI 
) prior to any investigator assessments.

• All remaining study visit procedures (e.g. laboratory and PK sample 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 EOTEI Visit Week 12. 
• Contact IRT to register the subject visit. 
• Prepare  the  corresponding  study  medication  packs  and  allow  to  adapt to room 
temperature for about 20 minutes before administration (dispense for home 
administrations, as required). 
• Provide guidance to subjects for self-administration prior to the first treatment 
administration (Section 5.5.4) at Randomization; from Visit Week 1 until End of 
Treatment Epoch II subjects should refer to the Instructions For Use (IFU) and proceed 
with self-administrations either at the site or they receive instructions for sub-sequent 
home administrations (H).  
• SIAQ PRE module should be performed once at Randomization  
• Subject self-administration assessment 
• Pre-filled syringe usability and hazard assessment should be done by site personnel, at 
Randomization Visit and at Visit Week 1  
• SIAQ POST module, as shown in Table 6-1

6.1 
Information to be collected on screening failures 
Subjects who sign the Informed Consent Form (ICF) and discontinue prior to randomization at 
the Randomization Visit are considered screening failures. 
If a subject discontinues before entering the double-blind Treatment Epoch I, the IRT must be 
notified within five days and the reason for not being randomized will be entered in the 
Screening Epoch Disposition electronic Case Report Form (eCRF). The Screening Visit date, 
the Demography eCRF, Informed Consent eCRF, Inclusion/Exclusion Criteria eCRF and 
Subject re-screening eCRF should be completed. The Adverse Event eCRF and a SAE Form 
should be completed for any serious adverse event (SAEs) that occurred during the Screening 
Epoch. The Withdrawal of consent eCRF should be completed if consent was withdrawn prior 
to the randomization. The Death eCRF should be completed in the case of a death during the 
Screening Epoch.  
All subjects who have signed the Informed Consent Form but not entered into the next treatment 
epoch will have the study completion page for the Screening Epoch, demographics, 
inclusion/exclusion, and serious adverse event (SAE) data collected. Adverse events that are 
not SAEs will be followed by the investigator and collected only in the source data. For all 
subjects who have signed the Informed Consent Form and entered the Treatment Epochs I and 
II of the study, adverse events occurring after informed consent was signed-off should be 
recorded on the Adverse Event eCRF.  
6.2 
Subject demographics/other baseline characteristics  
6.2.1 
Demographics 
Subject demographic data will include: date of birth (might be restricted to the year only due to 
applicable local data protection regulations), gender, race, ethnicity, and child-bearing potential 
(for females only). 
6.2.2 
Psoriasis medical history/previous psoriasis therapies 
The following information should be collected and entered in the Psoriasis History eCRF 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, e.g.: 
• Generalized pustular or pustular palmoplantar psoriasis 
• Guttate, palmoplantar, nail, inverse, scalp or erythrodermic psoriasis 
• 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

6.2.3 
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. 
6.2.4 
Co-morbidities – cardiovascular medical history 
Any information pertaining to cardiovascular medical history assessed prior to randomization 
should be recorded in the eCRF. 
6.2.5 
Relevant medical history/current medical conditions 
Relevant medical history and current medical conditions present before signing the informed 
consent should be recorded in the Medical History eCRF. 
Relevant medical history/current medical condition data includes data prior to signing of the 
informed consent and until the start of study treatment. 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.  
6.2.6 
Determination of the tuberculosis status 
Determination of the tuberculosis (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 (QuantiFERON-TB Gold assay). Any significant findings should 
be recorded in the TB assessment eCRF and the Medical History eCRF, as deemed necessary.  
QuantiFERON TB-Gold In-Tube assay 
A QuantiFERON® TB-Gold In-Tube assay (QFT) to screen a population for latent tuberculosis 
infection (Doherty et al 2008) will be used at Screening to evaluate the subjects’ eligibility for 
the study. 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 QuantiFERON®-TB Gold 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 6-1.  
• If the test result is negative, the subject may be randomized. 
• 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, 

Novartis 
Confidential 
Page 42 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
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. 
• 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. 
• If the second test is negative, the subject may be randomized. 
• If the second test is positive, the investigator should perform work-up as per local 
guidelines. 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. 
• If the second test is again indeterminate, the investigator should perform follow-up for 
the test result as per local procedures. Subjects tested 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.  Subjects positive for active TB per work-up are not 
eligible for the study. Subjects negative for TB per work-up (no signs of latent or active 
TB) may be randomized to the trial if the work-up 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 Epoch (within 4 weeks prior to 
randomization) and TB work-up will only be considered if it was completed 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 per work-up (no signs of latent or active TB) may be randomized to the trial.

Treatment exposure and compliance  
All doses of study treatment administration will be recorded on the appropriate Dosage 
Administration Record eCRF page (visit specific and summary pages). Compliance to the 
planned site administration schedule is expected to be high since the study treatment will be 
administered in the presence of the investigator or study personnel at pre-defined visits. 
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 (H) and empty medication 
boxes/outer packing/devices should be collected for compliance checks by field monitors. 
6.4 
Efficacy 
The following order should be applied when performing the efficacy assessments at study

6.4.1 
Investigator Global Assessment (IGA mod 2011) 
IGA mod 2011 will be conducted for overall psoriatic disease as indicated in Table 6-2. It is 
recommended that the same evaluator conduct the assessment throughout the study whenever 
possible. 
In collaboration with health authorities, in particular the FDA, the IGA mod 2011 scale 
(Table 6-2) has been developed based on a previous version of the scale used in secukinumab 
phase II studies. The only change from the phase II scale to phase III scale was to condense the 
very severe and severe subjects into one category “severe”. The explanations/descriptions of 
the points on the scale have been improved to ensure an appropriate differentiation between 
them. 
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. 
6.4.2 
Assessment of total Body Surface Area (BSA) and Psoriasis Area 
Severity Index (PASI) 
The investigator or qualified designee will complete the PASI assessment as indicated in Table 
6-3. 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 from the percentages of areas 
affected, including head, trunk, upper limbs and lower limbs (see below for PASI assessment). 
The following calculations will be done by Novartis: 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 6-3. 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 
• The buttocks are assessed as part of the lower limbs 
• When scoring the severity of erythema, scales should not be removed

The following definitions used in this study are based on CHMP guidelines for psoriasis 
(CHMP/EWP/2454/02 2004) to assess efficacy in conjunction with Investigators’s Global 
Assessment (IGA mod 2011): 
• PASI 50 response: subjects achieving ≥ 50% improvement (reduction) in PASI score 
compared to BSL are defined as PASI 50 responders 
• PASI 75 response: subjects achieving ≥ 75% improvement (reduction) in PASI score 
compared to BSL are defined as PASI 75 responders

• PASI 90 response: subjects achieving ≥ 90% improvement (reduction) in PASI score 
compared to BSL 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 6-3. 
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 Epoch 
I, at Visit week 12.  
6.4.4 
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 EMA 
for the clinical investigation of medicinal products for the treatment of psoriasis 
(CHMP/EWP/2454/02 2004). 
As indicated in Section 6.4.1, the IGA mod 2011 scale has been developed by Novartis in 
collaboration with health authorities, in particular the FDA. It is based on the previous version 
of the scale which was used in Phase II secukinumab studies, and has been used in all phase 
III 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.

Safety  
Blood withdrawals and safety assessments should be done prior to study treatment 
administration and should be taken as shown in Table 6-1 and in Appendix 2, Table 14-2. 
Appropriate safety assessments (e.g. evaluation of AEs and SAEs including injection site 
reactions) should be repeated after the dose is administered (Section 7).

6.5.1 
Physical examination 
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 6-1. 
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. 
6.5.2 
Vital signs  
Vital signs (including blood pressure and pulse measurements) will be assessed at every 
scheduled visit as indicated in Table 6-1. 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.  
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 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.  
6.5.3 
Height and weight  
Height and body weight will be measured as listed in Table 6-1. 
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.

6.5.4.1 
Hematology 
Hemoglobin, hematocrit, red blood cell count, white blood cell count with differential 
(neutrophils including bands, lymphocytes, monocytes, eosinophils, basophils) and platelet 
count will be measured at all scheduled study visits as  specified in Table 6-1. 
6.5.4.2 
Clinical chemistry 
Serum chemistry will include urea, creatinine, total bilirubin, AST (SGOT), ALT (SGPT), 
GGT, alkaline phosphatase, sodium, potassium, bicarbonate, calcium, phosphorous, total 
protein, albumin, uric acid, amylase and lipase. Serum chemistry will be measured at all 
scheduled study visits as specified in Table 6-1. 
6.5.4.3 
Fasting laboratory evaluations 
Fasting (8 hour duration with water ad libitum) laboratory tests will be assessed as indicated in 
Table 6-1.  
Subjects should avoid smoking within the hour preceding the blood draws.  
A central laboratory will be used for analysis of all fasting laboratory specimens. Details of the 
collections, shipment of samples and reporting of results by the central laboratory are provided 
to the investigators in the Laboratory Manual. 
6.5.4.3.1 High sensitivity C-reactive protein

Dipsticks will be provided by the central laboratory to the study sites for local urinalysis 
assessments. 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 at scheduled visits as indicated in Table 6-1. If needed conditional 
microscopy assessments will be optional. 
 
 
6.5.5 
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. 

Novartis

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 (QTcF) 
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 Medical 
History/Cardiovascular History/Current medical conditions/AE eCRF page as appropriate. 
6.5.6 
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 6-1.  
Any woman with a confirmed positive pregnancy test during Screening is not eligible for 
randomization. A positive urine pregnancy test during the treatment epochs of the study 
requires immediate interruption of study treatment until a serum β-hCG 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.

6.6.1.1 
Clinician Reported Outcomes (ClinRO) 
6.6.1.1.1 Usability and hazard assessment of the pre-filled syringe (2 mL syringe) 
The goal is to measure and evaluate the usability of the pre-filled syringe during observed use. 
The assessment of the ability to follow the Instructions For Use (IFU) will be performed for the 
first of the 2 mL injection at the two respective visits as well as the assessment of the hazards 
will be performed as a summary assessment for the 2 mL injection. 
Subjects will be instructed at Randomization through the site staff on how to self-inject via pre-
filled syringes following the Instructions For Use (IFU). After explanations/instructions given 
at the Randomization Visit, the injection will be self-administered by the subject into the 
appropriate injection site of the body. The delivery of the dose will be observed by 
investigator/site staff based on observation check lists at Randomization and Visit Week 1 
together with an assessment of potential administration hazards based on identified hazards list 
as well as non-directed querying for any observed problems during self-injection (Table 6-5). 
Primary usability assessment:  
• Assessment of successful 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 being minimally required 
are 1) removing the needle cap; 2) pinch the skin at injection site; 3) insert needle into skin; 
4) hold onto the finger flange; 5) fully depress plunger until end point; 6) hold the device in 
position for 5 seconds. As per Table 6-4 below, these 6 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:  
• Assessment of 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 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 6-4 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 6-5) will be computed by 
visit.

• 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. 
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 Instructions For Use (IFU) on how to self-inject via 
pre-filled syringe. 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 first self-injections at the respective visits 
(Randomization and Week 1) site staff will observe and complete the self-injection assessment 
checklist (Table 6-4) at the first of the injections at each visit (for the 2 mL form). The possible 
hazard assessment check list (Table 6-5) will be assessed for the injections at each of the 
applicable visits for the 2 mL form. The primary usability variables will be assessed based on 
binary (performed correctly: yes/no) response for the self-injection assessment check list (Table 
6-4). 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. For each item of the assessment checklists, the number and 
percentage of subjects with each response will be summarized. Where relevant, the number, 
percentage, average, standard deviation, minimum and maximum shall be presented.

additional problems (e.g. 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, e.g. 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 pre-filled syringe 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 pre-filled syringe 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, during Treatment Epochs I and II, 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.

Patient Reported Outcomes (PRO) 
6.6.1.2.1 Subject satisfaction assessment of Self-Injection Questionnaire (SIAQ) –  
2 mL syringe 
The Self-Injection Assessment Questionnaire (SIAQ) measures the overall subject experience 
with subcutaneous self-injection, and to investigate the psychometric properties (Keininger and 
Coteur 2011, Appendix 4). The SIAQ will be performed as a summary assessment for the 2 mL 
syringe at the visits as outlined in the visit schedule (see Table 6-1). 
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 self-injections as the visits indicated 
in Table 6-1, including Randomization. The PRE module includes 7 items grouped into three 
domains: Feelings about injections, Self-confidence and Satisfaction with self-injection, 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 (see Table 6-1).  
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 dosing (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 6-1. 
6.6.1.2.2 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 following validated instruments: 
• Dermatology Life Quality Index (DLQI)  

Novartis 
Confidential 
Page 56 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
• 
 
These questionnaires should be completed by subjects before they see the study physician 
(investigator or designee) who will perform the investigator assessments.  
All questionnaires will be completed in the language the respondent is most familiar with, at 
the scheduled visit before the subject sees the investigator for clinical assessments. The subject 
should be given sufficient space and time to complete the questionnaires. The study coordinator 
should check the questionnaires 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 (PASI, IGA mod 2011 
), 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 7 of the protocol. Investigator should not encourage the subject to change the 
responses reported in the completed questionnaires. 
Dermatology Life Quality Index (DLQI) 
The Dermatology Life Quality Index (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 6-1.

Pharmacokinetics  
At all study sites, blood samples will be collected for PK at the scheduled visits as indicated in 
Table 6-1. 
For a detailed description of the blood sampling schema, including time points, refer to the 
Blood Collection Log in Appendix 2, Table-14.1. 
Blood samples (approximately 2 mL, not less than 1.5 mL) will be collected into Serum 
Separator Tubes (SST). All blood samples will be taken by direct venipuncture. The blood 
sample will be allowed to clot over a minimum of 30 minutes at room temperature prior to 
harvesting of the serum. The serum will be obtained by centrifugation at approx. 2,500 
Revolutions Per Minutes (RPM) for 10 minutes. 
Thereafter, the serum samples will be placed on ice, split into 2 aliquots (labelled plain barrier 
polypropylene tubes) and then stored (within 30 minutes of serum collection by centrifugation) 
at -70˚C to -20˚C. The shipment to the central laboratory should be made on dry ice. The 
shipment instructions will be provided by the central laboratory. If possible, each aliquot of a 
sample should be sent separately to the central laboratory. The back-up samples should remain 
at the central laboratory whereas the second batch (the second pair) is delivered to an analytical 
laboratory. Back-up samples at the central laboratory will only be disposed after approval by 

Novartis 
Confidential 
Page 58 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
the corresponding Study Leader (typically six to 12 months after the clinical study report is 
published).  
The actual sample collection date and exact time of collection should be entered in the blood 
collection for PK eCRF or in the Unscheduled blood collection for PK eCRF, as appropriate. 
Sampling problems should be noted in the ‘Reason sample not taken’ section of the eCRF. 
6.6.3.1 
PK sample handling, labeling and shipment instructions 
A laboratory manual will be provided by the central laboratory with detailed information about 
sample collection, handling and shipment. 
Tubes and labels will be provided by the central laboratory with study/sample type and sample 
number pre-printed on the label. 
6.6.3.2 
PK sample stability  
Secukinumab is stable in serum samples for 4 months at -20°C or at -80°C. Long-term data 
confirmed a stability of 39 months at -65°C to -90°C. 
6.6.3.3 
PK analytical methods 
An ELISA method will be used for the bioanalytical analysis of AIN457 in serum, with an 
anticipated lower limit of quantification (LLOQ) of 80 ng/mL. The detailed method description 
to assess the Secukinumab concentration will be described in the bioanalytical raw data of the 
study and in the respective Bioanalytical Data Report (BDR).

Safety monitoring  
7.1 
Adverse events  
An adverse event (AE) is any untoward medical occurrence (e.g., 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. 
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 

Novartis 
Confidential 
Page 59 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
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 only if they fulfill at least 
one of the following criteria: 
• They induce clinical signs or symptoms,  
• They are considered clinically significant,  
• They require therapy.  
Clinically significant abnormal laboratory values or test results 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 Adverse Events eCRF under the signs, symptoms or 
diagnosis associated with them, accompanied by the following information: 
• The severity grade:  
• Mild: usually transient in nature and generally not interfering with normal activities 
• Moderate: sufficiently discomforting to interfere with normal activities 
• Severe: prevents normal activities 
• Its relationship to the study treatment (suspected: no/yes) 
• Its duration (start and end dates) or if the event is ongoing an outcome of 
not recovered/not resolved must be reported. 
• Whether it constitutes a serious adverse event (SAE - Section 7.2 for definition of SAE) 
and which seriousness criteria have been met. 
• Action taken regarding study treatment  
All adverse events must be treated appropriately. Treatment may include one or more of the 
following:  
• No action taken (e.g. further observation only)  
• Study treatment dosage increased/reduced  
• Study treatment interrupted/withdrawn  
• Concomitant medication or non-drug therapy given  
• Subject hospitalized/subject’s hospitalization prolonged (Section 7.2 for definition of 
SAE) 
• Its outcome (not recovered/not resolved; recovered/resolved; recovering/resolving, 
recovered/resolved with sequelae; fatal; or unknown) 
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 eCRF. Exceptions include cases 
when a) a new type of psoriasis is diagnosed e.g. 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 
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 (IN) 
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. 
7.2 
Serious adverse events  
7.2.1 
Definition of SAE  
A serious adverse event (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 (specify what this includes) 
• 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, e.g. 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. 

Novartis

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 (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 
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 (Annex IV, ICH-E2D Guideline). 
Any suspected transmission via a medicinal product of an infectious agent is also considered a 
serious adverse reaction. 
7.2.2 
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 within 24 hours of learning of its occurrence. Any SAEs 
experienced after the 12 weeks period following the last administration of study treatment 
should only be reported to Novartis if the investigator suspects a causal relationship to study 
treatment. Any SAEs reported up to the subject’s last visit will be reported in the AE eCRF. 
SAEs beyond that date 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 each specific 
component of study treatment (if study treatment consists of several components), complete 
the SAE Report Form in English, and submit the completed form within 24 hours to Novartis. 
Detailed instructions regarding the submission process and requirements for signature are to be 
found in the investigator folder provided to each site.  
Follow-up information is submitted as instructed in the investigator folder. Each re-occurrence, 
complication, or progression of the original event must be reported as a follow-up to that event 
regardless of when it occurs. The follow-up information should describe whether the event has 
resolved or continues, if and how it was treated, whether the blind was broken or not, and 
whether the 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 

Novartis 
Confidential 
Page 62 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
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.

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 collected in 
the Dose Administration Record (DAR) eCRF 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.

Pregnancy reporting  
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. 

Novartis

Pregnancy must be recorded on the Pharmacovigilance Pregnancy Form and reported by the 
investigator to the local Novartis Drug Safety and Epidemiology (DS & E) Department. 
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 pregnancy and unrelated to the pregnancy must be reported on 
the SAE Report Form.

Data review and database management  
8.1 
Site monitoring  
Before study initiation, at a site initiation visit or at an investigator’s meeting, a Novartis 
representative will review the protocol and eCRFs with the investigators and their staff. During 
the study, Novartis employs several methods of ensuring protocol and Good Clinical Practice 
(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 entries on the eCRFs, the 
adherence to the protocol and to GCP, the progress of enrollment, and to ensure that study 
treatment is being stored, dispensed, and accounted for according to specifications. Key study 
personnel must be available to assist the field monitor during these visits. Continuous remote 
monitoring of each site’s data may be performed by a centralized Novartis CRA organization. 
Additionally, a central analytics organization may analyze data & identify risks & trends for 
site operational parameters, and provide reports to Novartis Clinical Teams to assist with trial 
oversight. 
The investigator must maintain source documents for each subject in the study, consisting of 
case and visit notes (hospital or clinic medical records) containing demographic and medical 
information, laboratory data, electrocardiograms, and the results of any other tests or 
assessments. All information on eCRFs must be traceable to these source documents in the 
subject's file. The investigator must also keep the original Informed Consent Form signed by 
the subject (a signed copy is given to the subject). 
The investigator must give the monitor access to all relevant source documents to confirm their 
consistency with the eCRF entries. Novartis monitoring standards require full verification for 
the presence of informed consent, adherence to the inclusion/exclusion criteria, documentation 
of SAEs, and of data that will be used for all primary variables. Additional checks of the 
consistency of the source data with the eCRFs are performed according to the study-specific 
monitoring plan. No information in source documents about the identity of the subjects/subjects 
will be disclosed. 
8.2 
Data collection  
Designated investigator staff will enter the data required by the protocol into the RDC system. 
Designated investigator site staff will not be given access to the system until they have been 
trained.  
Automatic validation procedures within the system check for data discrepancies during and 
after data entry and, by generating appropriate error messages, allow the data to be confirmed 

Novartis 
Confidential 
Page 64 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
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.  
8.3 
Database management and quality control 
Novartis staff [or Contract Research Organization (CRO) working on behalf of Novartis] 
review the data entered into the eCRFs by investigational staff for completeness and accuracy 
and instruct the site personnel to make any required corrections or additions. Queries are sent 
to the investigational site using an electronic data query. Designated investigator site staff is 
required to respond to the query and confirm or correct the data. If the electronic query system 
is not used, a paper Data Query Form will be faxed to the site. Site personnel will complete and 
sign the faxed copy and fax it back to Novartis staff that will make the correction to the database. 
The signed copy of the Data Query Form is kept at the investigator site. 
Concomitant medications entered into the database will be coded using the WHO Drug 
Reference List, which employs the Anatomical Therapeutic Chemical classification system. 
Concomitant procedures, non-drug therapies and adverse events will be coded using the 
Medical dictionary for regulatory activities (MedDRA) terminology. 
Laboratory samples will be processed centrally and the results will be sent electronically to 
Novartis (or a designated CRO). 
ECG readings will be reviewed locally.  
Randomization codes and data about all study drug(s) dispensed to the subject will be tracked 
using an Interactive Response Technology (IRT). The system will be supplied by a vendor, who 
will also manage the database. The database will be sent electronically to Novartis (or a 
designated CRO). 
Each occurrence of a code break via IRT will be reported to the clinical team and monitor.  The 
code break functionality will remain available until study shut down or upon request of 
Novartis.  
The occurrence of relevant protocol deviations will be determined. After these actions have 
been completed and the database has been declared to be complete and accurate, it will be 
locked and the treatment codes will be unblinded and made available for data analysis. Any 
changes to the database after that time can only be made after written agreement by Novartis 
Development management.

300 mg (one 2 mL s.c. injection), and placebo  
• Week 12 up to Week 52 (end of study): secukinumab 300 mg (two 1 mL injections of 
150 mg s.c.), secukinumab 300 mg (one 2 mL s.c. injection), placebo-secukinumab 300 
mg (two  1 mL injections of 150 mg) and placebo-secukinumab 300 mg (one 2 mL s.c. 
injection) 
• Entire study: secukinumab 300 mg (two 1 mL injections of 150 mg s.c.), secukinumab 
300 mg (one 2 mL s.c. injection), placebo, any secukinumab 300 mg (two 1 mL injections 
150 mg s.c.), any secukinumab 300 mg (one 2 mL s.c. injection) 
Summary statistics for continuous variables will include N, mean, standard deviation, 
minimum, lower quartile, median, upper quartile, maximum. Summary statistics for discrete 
variables will be presented in contingency tables and will include absolute and relative 
frequencies. 
9.1 
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. 
Unless otherwise specified, mis-randomized subjects (mis-randomized in IRT) will be excluded 
from the randomized set. (mis-randomized subjects are defined as cases where IRT contacts 
were made by the site either prematurely or inappropriately prior to confirmation of the 
subject’s final randomization eligibility and double-blind medication was not administered to 
the subject). 
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 (ITT) 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. 
9.2 
Subject demographics and other baseline characteristics  
Unless otherwise specified, for subject demographics and other baseline characteristics, 
analyses will be based on the randomized set. 
9.2.1 
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. 
9.2.2 
Medical history 
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. 
9.3 
Treatments  
9.3.1 
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 (e.g. 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 treatment) or minimum of (last dose of 
the treatment + 84 days) and (last visit date).  
9.3.2 
Prior and concomitant medication 
Prior and concomitant medications will be summarized by treatment group for the different 
epochs 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.

9.4.2.1 
Primary endpoint (co-primary endpoints) 
The co-primary endpoints of this study are PASI 75 response and IGA mod 2011 0 or 1 response 
at Week 12. 
The statistical hypotheses are that secukinumab 300 mg (2 mL s.c. injection) 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.

j = 1,0. where 
• 0 corresponds to placebo 
• 1 corresponds to secukinumab 300 mg (2 mL s.c. injection) 
The following hypotheses will be tested: 
• 𝐻𝐻1: 𝑝𝑝1 −𝑝𝑝0 ≤0 versus 𝐻𝐻𝐴𝐴1: 𝑝𝑝1 −𝑝𝑝0  > 0, 
• 𝐻𝐻2: 𝑟𝑟1 −𝑟𝑟0 ≤0  versus 𝐻𝐻𝐴𝐴2: 𝑟𝑟1 −𝑟𝑟0  > 0  
In other words: 
H1: Secukinumab 300 mg (2 mL s.c. injection) is not superior to placebo with respect to PASI 
75 response at Week 12 
H2: Secukinumab 300 mg (2 mL s.c. injection) 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 exact logistic regression with treatment group; baseline 
bodyweight and baseline PASI score as explanatory variables. Odds ratios will be computed for 
comparisons of secukinumab dose regimen versus placebo in a pairwise fashion 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. 
The hypotheses 𝐻𝐻1 and 𝐻𝐻2 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 s.c. injection) has not been 
demonstrated.  
9.4.3 
Handling of missing values/censoring/discontinuations 
The following imputation methods will apply to the missing data: 

Novartis

Page 68 
Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
• Response variables based on PASI score and IGA mod 2011 categories will be imputed 
with multiple imputations (MI) method as primary imputation method. Multiple imputation 
(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 (e.g. premature study 
discontinuation, missed visit, administrative issues), exceptions will apply to the following: 
• 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 for visit x.  
• If a subject dropped out of the study prior to last scheduled visit and being responders 
consecutively at least for two preceding visits, the subject will be imputed as responder 
for the last scheduled visit. 
9.4.4 
Sensitivity analyses 
Sensitivity analyses will be performed as follows: 
Co-primary variables will be evaluated using the exact logistic regression as described in 
primary analysis method with non-responder imputations. 
9.5 
Analysis of key secondary variables 
9.5.1 
Efficacy variables  
9.5.1.1 
The key secondary endpoints of this study are planned as follows: 
• PASI 90 response at Week 12 
• PASI 100 response at Week 12 
9.5.1.2 
Testing strategy 
The following hypotheses will be tested sequentially and are included in the hierarchical testing 
strategy and type-I-errors will be set such that a family-wise type-I-error of 2.5% (one-sided) is 
kept: 
• H1: secukinumab 300 mg (2 mL s.c. injection) is not superior to placebo with respect to 
PASI 75 response at Week 12 
• H2: secukinumab 300 mg (2 mL s.c. injection) is not superior to placebo with respect to 
IGA mod 2011 0 or 1 response at Week 12 
• H3: secukinumab 300 mg (2 mL s.c. injection) is not superior to placebo with respect to 
PASI 90 response at Week 12 

Novartis

Clinical Trial Protocol (Version 00) 
 
Protocol No. CAIN457A2323 
 
• H4: secukinumab 300 mg (2 mL s.c. injection) is not superior to placebo with respect to 
PASI 100 response at Week 12 
• H5: secukinumab 300 mg (two 1 mL s.c. injections of 150 mg secukinumab) is not 
superior to placebo with respect to PASI 100 response at Week 12 
The graphical approach of (Bretz et al 2009) for sequentially rejective testing procedures is used 
to illustrate the testing strategy: 
Figure 9-1 
Testing strategy 
 
The efficacy variables involved in the above testing strategy will be analyzed analogously to 
the primary endpoints at Week 12, i.e., the exact logistic regression model with treatment group, 
baseline bodyweight and baseline PASI score as exploratory variables. Odds ratios will be 
computed for comparisons of secukinumab versus placebo utilizing the logistic regression 
model fitted. 
The testing sequence will continue to H3 at α (one-sided) only if both H1 and H2 have been 
rejected at α (one-sided). Similarly, the testing sequence will continue to H4 at α (one-sided) 
only if H3 testing has been rejected. In case, H4 has been rejected at α (one-sided), the 
corresponding alpha (α) will be passed to the next hypothesis corresponding to H5.

Analysis of other secondary and exploratory variables 
9.6.1 
PASI 50, PASI 75, PASI 90, PASI 100 and IGA mod 2011 0 or 1 
response over time 
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, 
pairwise comparison between each secukinumab dose regimen and placebo will be conducted 
using exact logistic regression model with treatment group, body weight stratum, and baseline 
PASI as effects.

9.6.6 
Safety variables  
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. 
9.6.6.1 
Adverse events 
Treatment emergent adverse events (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 will be counted only once with the highest severity at the system organ 
class level, where applicable.  
Tabulated summaries will be presented for Treatment Epoch I and all epochs put together.

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 
epochs. 
9.6.6.2 
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 (CTCG) 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). 
 
 
 
9.6.6.4 
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). 
9.6.7 
Health-related Quality of Life 
9.6.7.1 
Dermatology Life Quality Index (DLQI) 
Summaries will be based on the FAS and will be presented separately for each treatment group.  
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 

Novartis

the two secukinumab treatment groups versus placebo. The Van-Elteren test will be performed 
at each visit. Language of the questionnaire and geographical region will be the strata 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. 
9.6.8 
Patient Reported Outcomes (PRO) 
9.6.8.1 
Subject satisfaction assessment of Self-Injection 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 (Feelin about 
injections, Self-confidence domains and overall satisfaction of self-injection item) from the 
POST module taken after the two self-injections. Change in domain scores from PRE module 
will be summarized by visit and treatment group. 
9.6.10 
Pharmacokinetics  
All completed subjects with quantifiable pharmacokinetic (PK) measurements of secukinumab 
will be included in the pharmacokinetic data analysis. Serum concentrations will be expressed 
in mass per volume units. All concentrations below the limit of quantification or missing data 
will be labeled as such in the concentration data listings. PK concentrations will be summarized 
by visit and treatment group. In addition to mean, standard deviation, coefficient of variation, 
median and quartiles, the geometric mean and geometric coefficient of variation and n(log) will 
be presented.

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 pre-filled syringe 
group. 
Placebo-response rates between 3% and 7% have been reported in Papp et al 2005, Menter et 
al 2008, Leonardi et al 2008, and Papp et al 2008. 
9.8.1 
Primary endpoint (co-primary endpoint): 
With respect to the co-primary endpoint (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 70 subjects per group 
and assuming a response rate of 10% 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 pre-filled group based on 
Fisher’s exact test (nQuery Advisor 6.01, two group Fisher’s-exact test of equal proportions) is 
above 99% for PASI 75 response and IGA mod 2011 0 or 1 response. 
9.8.2 
Secondary endpoints(s): 
A power of 90% to show a response rate of 30% for PASI 100 in the secukinumab 300 mg 2 mL 
pre-filled group and 8% in the placebo group based on Fisher’s exact test results in a sample 
size of 70 subjects per group. Same power can be achieved if we apply the same assumption of 
PASI 100 response rate for secukinumab 300 mg 1 mL pre-filled group. 
A power of above 99% to show a response rate of 46% for PASI 90 in the secukinumab 300 mg 
2 mL pre-filled group and 8% in the placebo group based on Fisher’s exact test results in a 
sample size of 70 subjects per group.

Ethical considerations  
10.1 
Regulatory and ethical compliance  
This clinical study was designed and shall be implemented, executed and reported in accordance 
with the ICH Harmonized Tripartite Guidelines for Good Clinical Practice, with applicable 
local regulations (including European Directive 2001/20/EC, US CFR 21, and Japanese 
Ministry of Health, Labor, and Welfare), and with the ethical principles laid down in the 
Declaration of Helsinki. 
10.2 
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, or, if incapable of doing so, after 
such consent has been provided by a legally acceptable representative(s) of the subject. In cases 
where the subject’s representative gives consent, 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 assent by personally signing and dating the informed consent document or a 
separate assent form. Informed consent must be obtained before conducting any study-specific 
procedures (e.g. 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 ICH GCP guideline and regulatory requirements and is considered 
appropriate for this study. Any changes to the proposed Informed Consent Form suggested by 
the investigator must be agreed to by Novartis before submission to the IRB/IEC, and a copy 
of the approved version must be provided to the Novartis monitor after IRB/IEC approval. 
10.3 
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 (e.g., 
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. 
10.4 
Publication of study protocol and results 
The key design elements of this protocol will be posted in a publicly accessible database such 
as clinicaltrials.gov. In addition, upon study completion and finalization of the study report the 
results of this trial will be either submitted for publication and/or posted in a publicly accessible 
database of clinical trial results.

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 is an 
investigator allowed to collect additional data or conduct any additional procedures for any 
research related purpose involving any investigational drugs under the protocol. 
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.  
11.1 
Protocol amendments  
Any change or addition to the protocol can only be made in a written protocol amendment that 
must be approved by Novartis, health authorities where required, and the IRB/IEC prior to 
implementation, where required. Only amendments that are intended to eliminate an apparent 
immediate hazard to subjects 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, the reporting 
requirements identified in Section 7 Safety Monitoring must be followed.

Appendix 3: Scoring of the SIAQ 
The scoring of domains is performed in 2 steps: 
1. The raw item scores ranging from 1 to 5 are transformed into scores ranging from 0 (worst 
experience) to 10 (best experience). 
2. The transformed scores for items contributing to a domain are then averaged into a 
domain score.
