Notification of serious adverse events
A serious adverse event (SAE) is any event which is fatal or life-threatening, which requires 
or prolongs hospitalization, which is significantly or permanently disabling or incapacitating, 
which constitutes a congenital anomaly or a birth defect, or which is medically significant, 
may jeopardize the subject and may require medical or surgical intervention to prevent one of 
the outcomes listed above.
Any SAEoccurring in a subject from consent until 30 days after the last study visitmust 
be reported either on the paper SAE report form or via the electronic SAE form within the 
clinical data capture system (where available).
For SAEs reported using the paper SAE report form, the investigator will ensure that the 
form is completed and faxedby the investigator to the local Novartis Chief Medical Office 
& Patient Safety (CMO&PS)Departmentwithin 24hoursof learning of the occurrence of 
the SAE even if the SAE does not appearto be drug-related. Theoriginal SAE form, together 
with the fax confirmation sheet, must be kept with the case report forms at the study site.
For SAEs recorded electronicallyin the Novartis clinical data capture system, information 
should be entered, saved and e-signed within 24 hours of awareness of the SAE. 
Thesedata will automatically be submitted to Novartis Drug Safety & Epidemiology.

Purpose and 
rationale
This study is designed to evaluate the safety, tolerability, pharmacokinetics, 
pharmacodynamics, and preliminary therapeuticefficacy of multiple doses of 
CFZ533 monoclonal antibody in patients with primary Sjögren’s syndrome 
(pSS), which will provide data for furtherdevelopment of CFZ533 inthe 
treatment of pSS.
Primary Objectives
To assess the safety and tolerability of multiple intravenous infusionsof 
CFZ533 in patientswith primary Sjögren’s syndrome as measured by 
adverse events (AEs).
To compare the effect of multipleintravenous infusionsof CFZ533 versus 
placebo on the clinical disease activity of primary Sjögren’s syndrome 
patients as measured by the change of theEULAR Sjögren’s Syndrome 
Disease Activity Index (ESSDAI) after 12 weeks treatment.
Secondary 
Objectives
To assess the safety and tolerability of multiple subcutaneous doses of 
CFZ533in patients with primary Sjögren’s syndrome as measured by 
adverse events (AEs).
To compare the effect of multiple subcutaneousdosesof CFZ533 versus 
placeboontheclinicaldiseaseactivityofprimary Sjögren’ssyndrome 
patientsasmeasured bythechangeoftheEULARSjögren’sSyndrome 
DiseaseActivityIndex(ESSDAI)after12weekstreatment.
To assess the pharmacokinetics of multiple subcutaneous doses and 
multiple intravenous infusionsof CFZ533 in primary Sjögren’s syndrome 
patients.
To evaluate the effect of multiple subcutaneousdoses and multiple 
intravenous infusions of CFZ533 versus placebo on self-reported 
outcomes in primary Sjögren’s syndrome patients after 12 weeks 
treatment as measured by the EULAR Sjögren’s Syndrome Patient 
Reported Intensity (ESSPRI), the Short Form (36) Health Survey (SF-36) 
and the Multidimensional Fatigue Inventory (MFI) Questionnaire.
To evaluate the changes in the physician global assessment of the 
patient’s overall disease activity as recorded by a visual analog scale 
(VAS) after 12 weeks treatment.

Data analysis
Cohorts 1 and 2:
A longitudinal model describing ESSDAI change from baseline over time will 
be fitted for the controlled part of the study (up to Week 13) with the following 
covariates: baseline ESSDAI, baseline prednisone dose, treatment(placebo,
CFZ533
 s.c.or CFZ533 
 i.v), time as a continuous factor 
and a quadratic time effect, as well as a random intercept, a random slope 
and a random quadratic effect for subject. The change from baseline in 
ESSDAI at Week 13will be estimated from the model for alltreatments.
Inference will be made in the frequentist framework. The results from the 
primary analysis will be assessed against the following efficacy criteria to 
support internal decision making:
a statisticallysignificant reduction in ESSDAI at Week 13in the CFZ533 
group compared to placebo, at the one-sided 10% significance level, and,
an estimatedmean reduction in ESSDAI in the CFZ533 group to be 
5points or greater than placebo.
A positive sign of efficacy will be considered if both criteria are met.
Cohort 3:
Descriptive statistics and graphical displays will be used to summarize the PK 
concentrations in each treatment arm.
Key words
CFZ533, anti-CD40, primary Sjögren’s syndrome

Introduction
1.1
Background
Primary Sjögren’s syndrome (pSS) is a chronic autoimmune disease of unknown etiology. 
Itischaracterized by lymphoid infiltration and progressive destruction of exocrine glands 
(Youinou and Pers 2012).pSS is a common disorder, second only to rheumatoid arthritis (RA) 
in prevalence as a systemic autoimmune disease. The disease affects mainly women witha 
female/male ratio of 9:1 and can occur at any age. Although primarily organ-specific for the 
lacrimal,salivary and other exocrine glands, the inflammatory process can target any organ. 
Thus, the clinical features range from dryness, pain and fatigue affecting nearly all patients, to 
severe, extra-glandular and systemic involvement in a more limited subset.
Secretory gland failure can lead to disturbance of vision (lacrimal gland), swallowing difficulty and 
poor dentition (salivary gland) and sexual dysfunction (vaginal dryness). Further, many(reported as 
frequently as in 85% of patients)experience profound and disabling fatigue. Disease impact 
on quality of life (QOL) measures is substantial and comparative studies demonstrate 
pSSQoL scores quantitatively worse than in congestive heart failure or many cancers
(Segaletal2009;Kuenstner et al 2002;Komaroff et al 1996).Moreover, the increased B cell 
activity underlying pSS also results in an increased risk for malignant transformation, with 
lymphoma development occurring in 5% of Sjögren’s syndrome patients.
Treatment for pSS patients is limited to symptomatic care for the mucosal signs and 
symptoms. Glucocorticoids and typical disease-modifying anti-rheumatic drugs (DMARDs)
are mostly ineffective, and no pharmacologic intervention is effective against the severe, 
disabling fatigue. Despite a lack of convincing evidence of efficacy andbased on anecdotal 
evidence as well as experience from similar autoimmune diseases such as systemic lupus 
erythematosus, antimalarials (Tishler et al 2008), methotrexate (Winzer and Aringer2010) or 
azathioprine (Kaufmanetal1999
Corporate Confidential Information
) are sometimes used, in particularfor the treatment of 
extraglandular symptoms such as renal or joint involvement.
Although small trials with the B cell depleting agent rituximab havedemonstrated adegree of 
therapeutic efficacy, no proper, large randomized controlled trials have shown clear efficacy
with regard to extra-glandular and glandular disease manifestations.A disease modifying 
agentthat prevents secretory gland destruction and addresses extra-glandular disease 
manifestations would introduce a game-changing advance for the treatment of chronic pSS.

1.1.2
CD40/CD40L co-stimulation: a target for primary Sjögren’s syndrome
The CD40-CD154 co-stimulation pathway has long been considered as a target for the 
treatment of autoimmune diseases (Toubi and Shoenfeld 2004). Humans or rodents with 
loss-of-function or null mutants of CD40 fail to mount T-cell dependent immune response, do 
not undergo affinity maturation or differentiate into memory B cells. Further, pharmacological 
inhibition of CD40-CD154 interactions has been demonstrated to reduce/ameliorate 
autoimmune disease pathology in pre-clinical and clinical studies and can prolong allograft 
survival in non-human primates.Using monoclonal antibodies to target CD154 has been 
hampered by the occurrence of thromboembolic complications (Kawai et al 2000) so an 
alternative approach is to target the receptor, CD40. 
Several lines of evidence suggest that immune mediated pathology driven by or closely 
related to the CD40-CD154 pathway is essential in pSS. A hallmark of pSS is B cell 
hyper-reactivity such as formation of germinal center like structures (observed in 18-59% of 
patients), autoantibodies such asSSA, SSB or RF (Vossenkämper et al 2012). T cells 
predominate in pSS lesions, and are capable of provoking B cell hyperactivity and 
Igsecretion, and are directly involved in destruction of glands through Fas and 
perforin-mediated cytotoxicity (Manganelli and Fietta 2003). A portion of pSS patients have 
elevated serum sCD154; and T and B cell infiltrates of salivary glands show upregulation of 
CD40 and CD154.
Furthermore, CD40/CD154 mediated tissue inflammation may also contribute to pSS 
pathogenesis. Epithelial cell lines derived from pSS patients have constitutively up-regulated 
surface CD40 (Dimitriou et al 2002). Increased levels of micro-particles derived from 
platelets and also from leukocytes together with elevated sCD154 concentrations havebeen 
reported in pSS sera (Sellam et al 2009

Clinical data for other anti-CD40 monoclonal antibodies
CFZ533 is closely related to another Novartis compound, lucatumumab (HCD122).
DespitesharingidenticalCDR regions, the two antibodies can be differentiated by the 
engineered presence of a N297A mutation into the 1 Fc region ofCFZ533, rendering it 
Fc-silent.Incontrast, HCD122 has an unmutated Fc region and unlike CFZ533,is able to 
mediate ADCC. In phase I/II studies of lucatumumab in patients (n=approx. 164) with 
malignancies such as chronic lymphocytic leukemia, non-Hodgkin’s or Hodgkin’s 
lymphomas and myeloma, the most common reported grade 1 and 2 events occurred during 
the infusion and included chills (44%), pyrexia (33%), nausea (31%) and fatigue (26%). 
Themost commonly reported grade 3 or 4 adverse events, regardless of study drug 
relationship, were lipase elevations, dyspnea, and anemia. The majority of the adverse events 
was reversible and manageable; most were mild or moderate in severity. Elevations in lipase 
and amylase were observed but were primarily transient in nature and did not require medical 
intervention, were asymptomatic and imaging studies were negative for pancreatitis. 
Suchelevations, which are usually rare events and not typically associated with a fully-human 
IgG1 monoclonal antibody in clinical trials, are likely linked to the potent ADCC activity of 
the compound and CD40 expression of the ductal mucosa and liver parenchyma 
(Vostersetal2004). Of note, there were no thromboembolic complications in any of the 
Phase I/II studies with lucatumumab.
Recently published data (Goldwater et al 2013
Corporate Confidential Information
) also suggested a favorable safety and 
tolerability profile for the anti-human CD40 antagonist ASKP1240monoclonal antibody in 
the first-in-human, phase I study which evaluated single ascending doses of intravenous 
ASKP1240 (0.00003 –10 mg/kg) in healthy volunteers. There was no evidence of cytokine 
release syndrome or thromboembolic events. The antagonism of the CD40/CD154 interaction 
with ASKP1240 was overall safe and well tolerated at the doses tested.

Cohort 1
This cohort will randomize approximately 12 patients. For each patient, there will be a 
screening periodfrom Day -28to Day -2. Patientswho meet the eligibilitycriteria at 
screening will be admitted to baselineevaluations. Baselineevaluationsmay be started from
Day -6to allow completion of assessments on Day -1 prior to the treatment on Day 1. 
Allbaseline safety evaluation results must be available prior to dosingand meetingeligibility 
criteria. Eligiblepatients will enter the placebo-controlled period on Day 1 (Week 1) and will 
be randomized at a 2:1 ratio to receive treatment with either CFZ533or placebo.On Day 1, a 
dose of 
 CFZ533orplacebo will be administered by subcutaneousinjection(s.c.), 
followed by PK, pharmacodynamics (PD) and safety assessments for up to6hours. Patients 
will be discharged from the site on the same dayafter completion of all assessments provided 
there are no safety concerns.
Patients willreturn to the study center to receivethree s.c. doses of either CFZ533 or placebo 
(same as they have receivedon Day 1) on Day 15(Week 3), Day 29(Week 5) and Day 57
(Week 9) respectively.Safety and efficacy assessments will be conducted in these visits, 
On Day 85(Week 13), after safety and other assessmentsthatare assessments for the end of 
placebo-controlled period,allpatients will enter the open-label period and receive an 
open-label s.c. dose of 
 CFZ533. This is followed bythree open-labels.c. doses of

on Day 99 (Week 15), Day 113 (Week 17)and Day 141 (Week 21)
respectively. Safety and efficacy assessments will be conducted in these visits, PK and 
biomarker samples will be collected. The blind of the controlled period will be maintained for 
the investigator and the patient until the end of the study.
On Day 169 (Week 25),patientswill have assessments for the end of open-label period and 
enter follow-up period with no study medication administered. Patients will return to the study 
center for safety monitoringduring this period.
The end ofstudy visit will occur on Day225 (Week 33), which will include study completion 
evaluations followed by discharge from the study.

3.2
Rationale forstudy design
This study will be conducted in patients with active pSS for which no existing treatment has 
been proven effective against the underlying disease. 
 
Cohorts 1 and 2
Two different doses 
 of CFZ533 will be assessed in two 
separate cohorts.
A randomized, placebo-controlled, double-blind approach is used to eliminate potential bias 
in reporting safety and clinical efficacy data in this first, exploratory study in pSS patients. 
Patients will be randomized to CFZ533 or placebo in a 2:1 ratio in order to minimize exposure 
to placebo and to gather more data on CFZ533. Stratified randomization is done in order to 
limit imbalances between active and placebo arms in baseline intake of oral corticosteroids.
Theopen-labelperiod will administer CFZ533 to all patients including those who were 
administered placebo in the placebo-controlled period. This would provide potential treatment 
benefit to these patients, and collect further safety and efficacy
 data for CFZ533 in pSS patients.
After the open-label period, patients will entera follow up period for which a duration of 
8weeks (12 weeks after the last dosing with CFZ533) was chosento allow sufficient time for 
monitoring safety and exploring duration of response.
In addition to safety, efficacy estimated by the EULAR Sjogren’s Syndrome Disease Activity 
Index (ESSDAI) is chosen as a key endpoint of the study. The ESSDAI has been shown to be 
responsive in a retrospective analysis of a randomized controlled trial on rituximab, and was 
suggested to be a sensitive tool to assess efficacy of rituximab treatment 
(Moermanetal2014).The authors reported a significant lower ESSDAI in the rituximab 
group compared to the placebo group at week 12 and week 24, demonstrating some 
effectiveness in reducing disease activity in this small study. 
Cohort 3
Corporate Confidential Information
Because of the key objective ofthis cohort, no placebo control is required, and open-label 
treatment is justified. In Cohort 3, two treatmentarms areimplemented to assess whether two
loading regimens(multiple s.c. doses in treatment arm1, or single i.v. administrationin 
treatment arm2), followed by a maintenance regimen (multiple s.c. doses, both arms),areset 
to 12 weeks (Day 1 to Day 85) to establish steady state conditions for CFZ533 concentrations 
in plasma at a level similar to trough concentrations observed in Cohort2 
 
The follow-up period isset to 8 weeks (Day85 to Day141), 
(i)to follow the elimination of CFZ533 under conditions where the target is fully 
saturated (slow elimination), and under incomplete CD40 saturation (rapid 
elimination), and 
(ii)to characterize the capacity of the target mediated elimination pathway for CFZ533 
after 12-week treatment.

Rationale fordose/regimen, duration of treatment
No previous experience with an anti-CD40 blocking agent exists in human primary Sjögren’s 
syndrome.
 
 
 
 
 
 
 
 
 
Cohort 1 (subcutaneous 
The 2-week dosing interval at the start is meant to ensure full CD40 saturation on peripheral 
Bcells as well as complete suppression of CD40-CD154 interaction in tissues after 
subcutaneous administration. By the end of the 12-week treatment period, clinically 
meaningful changes in the primary endpoint and in other key efficacy and biomarker readouts 
are expected to occur. Based on published results with a single cycle of rituximab, significant 
clinical responses in pSS patients can be detected as early as at week 5, with maximum effect 
shown at week 12 (Meijeretal2010). During the additional 12-week open label extension 
period, further data regarding longer termefficacy and safety of CFZ533 will be collected.

In Cohort 3, the dose/regimen in treatment arm 1 and in treatment arm 2 were set to assess 
whether a loading regimen (i.v. or s.c.), followed by a s.c. maintenance regimen is able to 
deliver steady state plasma concentrationssimilar to the i.v.regimentested in Cohort 2, and

3.4
Rationale for choice of comparator
In studyCohorts 1 and 2, the placebo to CFZ533will be used as comparator to provide 
objective evidence of potential AEs and other safety data, as well as clinical efficacy and 
PDdata generated from patients exposed to the experimental therapy. Since there is no 
established, clinically effective disease modifying treatment for patients with pSS, potential 
treatment with placebo (on top ofstandard of care therapy, if necessary) is justified.
3.6
Risks and benefits
3.6.1
Potential benefit
To date, no evidence-based, systemic therapy has been available for pSS patients. Based on 
the established role of both B cells and T cells in pSS pathogenesis, CFZ533, via the 
inhibitionof T cell dependent B cell functions, autoantibody production, ectopic germinal 
center formation along with a concurrent blockade of the parenchymal CD40 mediated 
signaling in salivary glands, has a potential therapeutic benefit.
If CFZ533 has clinical efficacy, all patients participating in the present trial can experience 
this benefit as placebo patientsin Cohorts 1 and 2will be switched to CFZ533 after 12weeks 
(in the open-label period). However, CFZ533 has never been used in patients with pSS,so at 
this stage, no statement can be made of its efficacy in treating this disease.
3.6.2
Potential risks associated with exposure to CFZ533and their 
mitigation
Corporate Confidential Information
Currently, limited data exists regarding the use of agents that block the CD40/CD154pathway. 
 
 
 The current IB (Section 6, Investigator Guidance) also provides
detailed instructions regarding the risks and their mitigation.

Acutehypersensitivity
Hypersensitivity or infusion reactions can manifest with itching, flushing, headache, 
nausea/vomiting, hypotension, urticaria, bronchospasm, or angioedema. 
 
 
 
 
 
Infections
Corporate Confidential 
Information
Subjects treated with CFZ533 may be at an increased risk of infection. CD40 ligation is 
linkedto the functional activity of antigen presentation, as well as T-cell priming, B-cell 
differentiation, antibody production and immune memory. Administration of CFZ533 is 
expected to result in general immunosuppression with a decreased capacity to mount a 
response to novel immunogens, including those of bacterial, viral, fungal and parasitic origin 
when full receptor occupancy has been achieved.
Although the ability to mount a primary immune response will be affected by CFZ533, the 
memory B-cell repertoire and immune recall response should remain intact and protective. 
Inaddition, subjects will have adequate preformed antibody to maintain protective humoral 
response for extended periods of time (months).
Subjects enrolled in the current studywillbe monitored regularly and carefully for signs and 
symptoms which might indicate a severe infection.Subjects willbe informed to contact the 
study physician if they present with signs and symptoms of an infection such as fever, nausea, 
myalgia, headache,arthralgia, chills, diarrhea, stiff neck, and malaise for further assessment 
and treatment if necessary.

Vaccination
Vaccination of subjects during treatment with CFZ533 and prior to clearance of the antibody
is likely to result in therapeutic failure (i.e., non-protective antibody titers) due to the 
pharmacologic activity of the antibody. For subjects participating in this study, all 
vaccinations should be up to date based on local guidelines. Administration of live attenuated 
agents will be prohibitedreceiving CFZ533 treatment in the current study.
Immunogenicity
 
 
Extrapolation of immunogenicity risks from healthy subjects to pSS 
patients is unknown and blood samples will be collected during this trial to assess this.
Thrombosis
There is a minimalrisk for thromboembolic complications when targeting this co-stimulatory

In the open-label Cohort 3, the subjects will be randomized in a 1:1 ratio to one of the 
following two treatment arms:
Treatment arm 1: CFZ533 will be given 
 weekly on 4 occasions (Days1, 8, 
15 and 22; loading regimen), followed by 
 s.c. weekly on 9 occasions 
(maintenance regimen starting on study Day 29, last dose on Day 85).
Treatment arm 2: CFZ533 
 i.v. onDay 1, followed by

12occasions (maintenance regimen starting on study Day 8, last dose on Day85).
The 
 s.c doses will consist of 4injections or 2injectionsof 1mLCFZ533 
 respectively.
5.3
Treatment assignment
Randomization numbers will be assigned in ascending, sequential order to eligible subjects 
(see Section 5.5.1for details). The investigator will enter the randomization number on the eCRF.
The randomization numbers will be generated using the following procedure to ensure that 
treatment assignment is unbiased and concealed from subjects and investigator staff. 
Arandomization list for each cohort will be produced by or under the responsibility of 
Novartis Drug Supply Management using a validated system that automates the random 
assignment of treatment arms to randomization numbers in the specified ratio. 
Therandomization scheme for subjects will be reviewed and approved by a member of the 
Novartis IIS Randomization Group.
Randomization procedure for central management of randomization numbers:
When an eligible patient at a participating study site is ready to be randomized into the study, 
the steps below will be followed:
The site designee will complete a Randomization Request form and email to the Novartis 
designee.
On receivingthe Randomization Request form, the Novartis designee will write the next 
available randomization number within the randomization list for the corresponding part 
of the study on the form and email back.
On receiving the allocated randomization number, the unblinded pharmacist or authorized 
designee will use the information on the completedform to ensure that the patient receives 
the correct study medication, according to the provided randomization list.

Amended Protocol Version v07 Clean
Protocol No. CCFZ533X2203
After inclusion of each new patient, the site designee will countersign the Randomization 
Request form, and email it back to the Novartis designee to document the correct assignment 
of the patient’s randomization number and the date the patient received their first dose of 
study medication.
5.4
Treatment blinding
Cohorts 1 and 2 aredouble-blind: subjects, investigator staff, persons performing the 
assessments, and data analysts will remain blind to the identity of study treatments according 
to the specifications provided in Appendix 6. Randomization data are kept strictly confidential 
until the time of unblinding for the respective person(s). Furtherinformation regarding 
blinding (and unblinding) is presented in Appendix 6.
The identity of the treatments will be concealed by the use of study drugs that are all identical 
in packaging, labeling, schedule of administration, appearance, taste and odor.
An unblinded pharmacist at the investigator site will prepare the study treatment for injection
from the bulk open-labeled supplies.
The blind of the controlled periodof the study will be maintained in the open-label periodfor 
the investigator and the patient until the end of the study.
The PK/PDbioanalystswill be unblinded during the clinical study, but will not provide 
individual PK/PDdata prior to database lock, to maintain the study blind.
The necessary safety review may lead to the Novartis study team being inadvertently 
unblinded;however,this information will not be communicated to the investigator.
Unblinding will only occur in the case of patient emergencies (see Section 5.5.11) and at the 
time of the interim analysis and at the conclusion of the study.
Cohort 3 will be open-label.However, subjects andinvestigator staff remain blinded to the 
study treatment allocation (dosing arm) until first dosing. Furtherinformation regarding 
blinding (and unblinding) is presented in Appendix 6.
5.5
Treating the subject
5.5.1
Subject numbering
Screening number
Each subject screened is assigned a unique screening number. The screening number is a 
combination of the center number that is provided by Novartis, and a three digit number 
starting with 001 for each subject which is assigned by the Investigator. Therefore, if the 
center number is 1 (any leading 0’s in the center number are dropped) the screening numbers 
will be assigned such as 1001, 1002, 1003 in ascending order. If the center number is 2 
(or0002), the screening numbers will be 2001, 2002, 2003 in an ascending order.

Protocol No. CCFZ533X2203
Randomization number
If the subject is deemed eligible for the study and will commence dosing, a randomization 
number will be assigned. Once assigned to a subject, a randomization number will not be reused.
The randomization number becomes the definitive subject number as soon as a subject 
receives the first dose of the respective study treatment.
There should be a source document maintained at the site which links the screening number to 
the randomization number (once assigned). This source document should be provided to all 
appropriate parties (i.e.,Central Laboratory) as soon as this is available.
Cohort 1
Subjects will be assigned randomization numbers 5101-5130 in the first stratum 
(baselineintake of oral corticosteroids = yes) and randomization numbers 5201-5230 in the 
second stratum (baseline intake of oral corticosteroids = no).
Replacement subjects will be assigned randomization numbers 6101-6130in the first stratum 
and 6201-6230 in the second stratum. If a subject requires a replacement, the replacement 
subject will be assigned a randomization number corresponding to the original subject 
(e.g.,Subject 6103 would replace Subject 5103).Replacements are envisaged only for subjects 
dropping out for reasons other than safety without at least one post-baselineESSDAI result.
Cohort 2
Subjects will be assigned randomization numbers 5601-5630 in the first stratum 
(baselineintake of oral corticosteroids = yes) and randomization numbers 5701-5730 in the 
second stratum (baseline intake of oral corticosteroids = no).
Replacement subjects will be assigned randomization numbers 6601-6630 in the first stratum 
and 6701-6730 in the second stratum. If a subject requires a replacement, the replacement 
subject will be assigned a randomization number corresponding to the original subject 
(e.g.,Subject 6603 would replace Subject 5603). Replacements are envisaged onlyfor subjects 
dropping out for reasons other than safety without at least one post-baseline ESSDAI result.
Cohort3
Subjects will be assigned randomization numbers 5801-5840.

Handling of study treatment
5.5.3.1 Handling of investigational treatment
Investigational treatment must be received at the study site by a designated person, handled 
and stored safely and properly, and kept in a secured location to which only the Investigator 
and designated staff have access. Upon receipt, the study drugs should be stored according to 
the instructions specified on the labels. Clinical supplies are to be dispensed only in 
accordance with the protocol. Technical complaints are to be reported to the respective 
Novartis CPO Quality Assurance. Storage conditions must be adequately monitored and 
appropriate temperature/humidity logs maintained as Source data.
The Investigator must maintain an accurate record of the shipment and dispensing of study 
drug in a drug accountability ledger. Drug accountability will be noted by the Monitor during 
site visits and/or at the completion of the trial.
All drug supplies are to be used only for this protocol and not for any other purpose. 
Unlessspecifically instructed by Novartis, the Investigator must not destroy any drug labels, 
or any partly used or unused drug supply.
At the conclusion of the study, and, if allowed during the course of the study (e.g.,an 
un-blinded monitor), the Investigator will provide a copy of the drug accountability ledgerto 
the Monitor.
Only after receiving a written authorization by Novartis, the Investigator/designee will send 
all the unused and partly used drug supplies as well as the empty containers to the address 
provided at the time of authorization for destructionorhave the unused and partly useddrug 
supplies as well as the empty containers destroyed by the site’s pharmacist, providing a drug 
destruction certificate.
5.5.3.2 Handling of other study treatment
Not applicable.
5.5.4
Instructions for prescribing and taking study treatment
CFZ533,or matching placebo(Cohorts 1 and 2only),will be administered as an s.c. injection
in Cohort 1, i.v. infusion in Cohort 2, or i.v. infusion and s.c. injection in Cohort 3by the 
study center personnel following the instructions and using the material as described and 
specified in the Pharmacy Manual.
In Cohort 1, the subjectswill be weighed at the baseline visit and this weightvalue 
will be used for studymedication preparationand the calculation of the dose.
In Cohort 2, the dose for administration to subjectswill be calculated from the 
individual subjects’ body weight obtained atthe mostrecentpre-dose visit.

In Cohort 3, the i.v. dose (Day1) for administration to subjects randomized to 
treatment arm2will be calculated from the individual subject’s body weight obtained 
at Baseline visit.All s.c. doses in this cohort
 are administered as flat 
doses (not adjusted to body weight)
A physician shall be available,e.g.,by pager, DECT etc. at all other times throughout the study.
All dosages prescribed and dispensed to the subject and all dose changes during the study 
must be recorded on the Dosage Administration Record eCRF.
5.5.5
Permitted dose adjustments and interruptions of study treatment
Study drug dose adjustments and/or interruptions are not permitted in this study; in case of an 
AE or for any reason (e.g.,non-compliance, operational hurdle) resulting in a deviation from 
the required dosing scheme, consultation and agreement with Novartis will be necessary to 
decide whether the subject can continue or needs to be withdrawn from the study. Any change 
in dosingmust be recorded on the Dosage Administration Record eCRF.
In case of notable adverse events, SAEs including loss of efficacy and/orassociated PK/PD 
data collected during the study, changes to a different dosing scheme level may be considered 
and implemented via a protocol amendment.
Uponreview data at interim analysis, dose adjustment for study drug may occur. This will be 
implemented via a protocol amendment.Details are provided in Section 9.8.
5.5.6
Recommended treatment of adverse events
Parenteral administration of monoclonal antibodies can be associated with acute, severe 
reactions (occurring within the first few hours post dose) secondary to hypersensitivity, 
immunogenicity, or ADCC-mediated cell depletion. Although such events are more likely to 
occur during intravenous administration (infusion reaction), they cannot be fully excluded 
when the antibody is administered as a subcutaneous injection.
Injection site reactions can also be noted during or after subcutaneous administration and are 
usually less severe than infusion reactions, however, may still require medical attention and 
treatment.
In this study, CFZ533 will be administered as intravenous infusionandsubcutaneous injection. 
 
Patients will be monitored at the site for at least 6 hours post dose or longer in Cohort 1, at 
least 2 hours post dose or longer in Cohort 2, and at least 1 hourafter i.v.infusionand 
30minutes afters.c.injectionsin Cohort 3at the discretion of the Investigator to ensure 
adequate safety monitoring. In case of any signs of an acute reaction, clinical treatment will 
be provided as determined by the treating physician on a case-by-case basis and depending on 
the severity, using symptomatic treatment, anti-histamines, NSAIDs, acetaminophen, 
intravenous fluids, corticosteroids, or adrenaline.

Concomitant treatment
Use of artificial tears and artificial saliva/salivary stimulants(e.g.,cevimeline, pilocarpine) by 
the patient during participation in the protocol is permitted at the discretion of the treating 
physician. Amount and frequency of use should be recorded at each visit. Forassessments in 
Cohorts 1 and 2, the salivary stimulantsshould be stoppedwithin 12hours prior to, or during 
assessment of clinical disease outcome measurements. Artificial tears and artificial saliva are 
to beprovided by the study center or personal physicianif needed, and should not be used
4hours prior to, or during assessment of clinical disease outcome measurements.
Currently, concomitant use of corticosteroidsis allowed at a dose of max 10 mg per 
day(prednisone or equivalent) and no immunosuppressives such as cyclosporine,
cyclophosphamide, or mycophenolateare allowed. Stable dose of methotrexate(up to 25 mg 
per week), azathioprine (up to 100 mg per day)and/or antimalarials are permitted.Any other 
drug with a potential immunosuppressiveeffect that is not specifically mentioned in the 
Inclusion/Exclusion criteria, should be discussed with the Sponsor on a case by case basis. 
If,based on the patient condition(such as severe extraglandular manifestation,or major 
disease worsening)a corticosteroid dose above 10 mg (prednisone or equivalent) per day or 
animmunosuppressivemedicationis necessary, the patient may have to be withdrawn from 
the study. This will be decided on the basis of a case by case evaluation by both the 
investigator and Sponsor.
The investigator should instruct the subject to notify the study site about any new medications 
he/she takes after the start of the study drug.
All prescription medications, over-the-counter drugs and significant non-drug therapies 
(including physical therapy and blood transfusions) administered or taken within the

Discontinuation of study treatment
Study “Stopping rules”
The following stopping rules, based on potential toxicities, will serve as the basis for placing 
the study on hold. Although the stopping criteria do not incorporate an absolute requirement 
for causality, the potential relationship between an adverse event and CFZ533 will be 
evaluated carefully on a case-by-case basis between the Sponsor and the Investigator.
Following a review of the adverse event(s), a decision to permanently discontinue enrollment 
or re-initiate dosing will be made jointly by the Investigator and Sponsor.
As a guidance, dose limiting toxicities (DLTs) will be assessed according to the 
standardizedtoxicity grading scale, the NCI Common Toxicity Criteria for Adverse Events 
(NCI-CTCAE/v4.03, Reference http://evs.nci.nih.gov/ftp1/CTCAE/About.html).
Any study treatment related death,

Subjectsmay voluntarily discontinue the studyfor any reason at any time.
The Investigator should discontinue study treatment for a givensubject if, on balance, he/she 
believes that continuation would be detrimental to the subject’s well-being.
Study treatment mustbe discontinued under the following circumstances:
Subject withdraws consent,
Pregnancy,
CTCAE Grade 3-4allergic reaction,
Major worsening of primary Sjögren’ssyndrome as judged by the Investigator 
(e.g.,severe CNS or renal complications, or increase from baseline in ESSDAI of at least 
7points after more than 8 weeks of treatment(as a guidance),
Acute, severe infection as judged by the investigator,
Significant changes in standard coagulation test, such as prothrombin time (PT)or
activated partial thromboplastin time (aPTT),suggesting an increased risk for 
hypercoagulabilityor any signor symptomof a thromboembolic event.
Discontinuation of study treatment will be at the discretion of the Investigator, under the 
following circumstances:
Any other protocol deviation that results in a significant risk to the subject’s safety

Amended Protocol Version v07 Clean
Protocol No. CCFZ533X2203
The appropriate personnel from the site and Novartis will assess whether studytreatment 
should be discontinued for any subject whose treatment code has been broken inadvertently 
for any reason.
Subjectswho discontinue study treatmentshould NOT be considered withdrawn from the 
studyUNLESS they withdraw their consent (see Section 5.5.11). They should return for the 
assessments indicated by an asterisk (*) in the assessment table. If they fail to return for these 
assessments for unknown reasons, every effort should be made to contact them as specified in 
Section5.5.12.
5.5.11
Withdrawal of consent
Subjects may voluntarily
 withdraw consent to participate in the study for any
 reason at any
 time.
Withdrawal of consent occurs only when a subject does not want to participate in the study 
anymore and does not want any further visits or assessments and does not want any further 
study related contacts and does not allow analysis of already obtained biologic material.
If a subject withdraws consent, the investigator must make every effort to determine the 
primary reason for this decision and record this information. Study treatment must be 
discontinued and no further assessments conducted. Allbiological material that has not been 
analyzed at the time of withdrawal must not be used. Further attempts to contact the subject 
are not allowed unless safety findings require communicating or follow-up.
5.5.12
Loss to follow-up
For subjects whose status is unclear because they fail to appear for study visits without stating 
an intention to withdraw, the investigator should show “due diligence”by documenting in the 
source documents steps taken to contact the subject, e.g.,dates of telephone calls, registered 
letters, etc. A subject should not be considered lost to follow-up until his/her scheduled end of 
study visit would have occurred.
Subjects dropping out for reasons other than safety without at least one post-baseline ESSDAI 
result will be replaced by an equal number of newly enrolled subjects.
5.5.13
Emergency breaking of assigned treatment
Cohorts 1 and 2: 
Emergency unblinding in Cohorts 1 and 2 should only be undertaken when it is essential to 
treat the subject safely and efficaciously. Most often,study treatmentdiscontinuation and 
knowledge of the possible treatment assignments are sufficient to treat a study subject who 
presents with an emergency condition. A complete set of emergency code break cards will be 
provided to the investigator site(s) and a complete set will be available at Novartis. Allcode 
break cards must be retained until the end of the study and returned to Novartis. They must be 
stored in a secure place but be accessible in case of emergency. The investigator will receive a 
blinded code break card for each subject, with the details of drug treatment covered by a 
removable, scratch-off cover. In an emergency, the scratch-off cover can be removed to 
determine the treatment. The scratch-off covers are not to be removed for any reason other 
than an emergency. When the investigator removes the scratch-off cover he/she must note the 


Novartis

date, time, and reason for removing it and retain this information with the case report form 
documentation. The unblinded treatment code should not be recorded on the eCRF.
Theinvestigator must also immediately inform the Novartis local monitor that the code has 
been broken.
It is the investigator’s responsibility to ensure that there is a procedure in place to allow access 
to the code break cardsin case of emergency. If appropriate, the investigator will inform the 
subject how to contact his/her backup in cases of emergency when he/she is unavailable.
An assessment will be done by the appropriate site personnel and the Sponsor after an 
emergency unblinding to assess whether or not study drug should be discontinued for a given 
subject and, if applicable, whether the subject can continue intothe next trial phase 
(e.g.,anunblinded extension).
Cohort 3 will be open-label.
5.5.14
Study completion and post-study treatment
Each subject will be required to complete the study in its entirety and thereafter no further 
study treatment will be made available to them. The study will complete when the last subject 
completes their Study Completion visit, and any repeat assessments associated with this visit 
have been documented and followed-up appropriately by the Investigator.
After study participation, the patients will continue to be treated by his/her general
practitioner according to the local standard clinical management related to the underlying
disease.
The investigator must provide follow-up medical care for all subjects who are prematurely 
withdrawn from the study, or must refer them for appropriate ongoing care.
5.5.15
Early study termination
The study can be terminated at any time for any reason by Novartis. Should this be necessary, 
the subject should 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 
ensurethat adequate consideration is given to the protection of the subject’s interests. 
Theinvestigator will be responsible for informing IRBs/IECs of the early termination of the 
trial.

Visit assessments
The full Assessment scheduleis presented at the end of the synoptic section, above.
Subjects should be seen for all visits on the designated day with an allowed “visit window” as 
shown below:
1. Baseline visit assessments(V2, Day -1, Week -1)can be started from Day -6. 
2. VisitV3 (Day 1,Week 1) should occur within 7days after the Baseline visit (V2, Day -1, 
Week -1)
3. Subsequent visits starting from V4 up to V12in Cohorts1 and 2, orfrom V4up to V15in 
Cohort 3, inclusive: ±3day
4. Visits V13 , V14 and V777in Cohorts 1 and 2, orV16, V17, V18 and V777:±7days
Every effort shouldbe made to take the pharmacokinetic samplesat the protocol specified 
time. When assessments are scheduled to be performed at the same time-point, thesewill be 
taken after the pharmacokinetic sampleand other blood samples.
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.
At a minimum, subjects will be contacted for safety evaluations during the 30 days following 
the last study visit or following the last administration of study treatment if there are 
post-treatment follow-up visits (whichever is later), including a final contact at the 30-day 
point. Documentation of attempts to contact the subjectshould berecorded in the source 
documentation.
6.1

Subjects should maintain their usual diet and life habits during the entire study.
6.2
Subject demographics/other baseline characteristics
Subject demographic and baseline characteristic data to be collected on all subjects include: 
date of birth, age, sex, race, predominant ethnicity.
Relevant medical history/current medical conditions data includes data until signature of 
informed consent. Where possible, diagnoses and not symptoms will be recorded.
The date of original diagnosis of primary Sjögren’s syndrome shouldbe recorded.

ofthe ESSPRI and other patient-based assessments,
 
 
6.4.1
ESSDAI
The ESSDAI (Appendix 4) is an established disease outcome measure for Sjögren’s syndrome.
The instrument contains 12 organ-specific domains contributing to disease activity. For each 
domain, features of disease activity are scored in 3 or 4 levels according to their severity. 
These scores are then summed across the 12 domains in a weighted manner to provide the 
total score.
6.4.2
ESSPRI
The ESSPRI (Appendix 5

A complete physical examination will include the examination of general appearance, skin, 
neck (including thyroid), eyes, ears, nose, throat, lungs, heart, abdomen, back, lymph nodes, 
extremities, vascular and neurological. If indicated based on medical history and/or symptoms, 
rectal, external genitalia, breast, and/or pelvic exams may be performed.
Information for all physical examinations must be included in the source documentation at the 
study site and will not be recorded the eCRF. Significant findings that are present prior to 
informed consent are included in the Relevant Medical History eCRF. Significant findings 
observed after informed consent signature which meet the definition of an Adverse Event 
must be appropriately recorded on the Adverse Event eCRF.

6.5.2 
Vital signs
Vital signs include blood pressure (BP) and pulse measurements. After the subject has been 
sitting for at least 3 minutes, with back supported and both feet placed on the floor, systolic 
and diastolic BP will be measured using a validated device, with an appropriately sized cuff. 
Incase the cuff sizes available are not large enough for the subject’s arm circumference, a 
sphygmomanometer with an appropriately sized cuff may be used.
If heart-rateor blood pressureis out-of-range at screening orbaseline, the Investigator may 
obtain two additional readings,so that a total of up to three consecutive assessments are made, 
with the subject seated quietly for approximately five minutes preceding each repeat 
assessment. Atleast the last reading mustbe within the ranges provided above in order for 
the subject to qualify.
6.5.3
Height and weight
Height in centimeters (cm) and body weight (to the nearest 0.1 kilogram [kg] in indoor 
clothing, but without shoes) will be measured.
6.5.4
Laboratory evaluations
In the case where a laboratory assessment that is listed in the inclusion/exclusion criteria is 
outside of a protocol-specified rangeat screening or baseline, the assessment may be 
repeated once prior to randomization. If the repeat value remains outside of protocol-specified 
ranges, the subjectis excluded from the study.
In the case where a laboratory range is not specified by the protocol, but is outside the 
reference range for the laboratory at screening or baseline, a decision regarding whether the 
result isof clinical significance or not shall be made by the Investigator and shall be based, in 
part, upon the nature and degree of the observed abnormality. The assessment may be 
repeated once prior to randomization.
In all cases, the Investigator must document in the source documents, the clinical 
considerations(i.e., result was/was not clinically significant and/or medically relevant) in 
allowing or disallowing the subjectto continue in the study.
Clinically relevant deviations of laboratory test results occurring during or at completion of 
the study must be reported and discussed with Novartis personnel. The results should be 
evaluated for criteria defining an adverse event and reported as such if the criteria are met. 
Repeated evaluations are mandatory until normalization of the result(s) or until the change is 
no longer clinically relevant. In case of doubt, Novartis personnel should again be contacted.
6.5.4.1 Hematology
Hemoglobin, hematocrit, red blood cell count, white blood cell count with differential 
(e.g.,neutrophils, basophils, eosinophils, monocytes, lymphocytes) and platelet count will be

If the total bilirubin concentration is increased above 1.5 times the upper limit of normal, 
direct and indirect reacting bilirubin should be differentiated.
6.5.4.3 Urinalysis
A midstream urine sample (approximately30 mL) will be obtained, in order to avoid 
contamination with epithelial cells and sediments, and allow proper assessments.
A semi-quantitative “dipstick”evaluation for the following parameters will be performed: 
specific gravity, pH, glucose, protein, bilirubin, ketones, nitrite, leukocytes and blood.
If the dipstick result is positive for protein, nitrite, leucocytes or blood, the sample will be sent 
for microscopic analysis of WBC, RBC and casts.

Electrocardiogram (ECG)
The Fridericia QT correction formula (QTcF) should be used for clinical decisions.
Single 12 lead ECGs are collected. The original ECGs, appropriately signed, should be 
collected and archived at the study site.
Each ECG tracing should be labeled with study number, subject initials,subject number, date 
and time, be appropriately signed and dated to confirm review and filedin the study site 
source documents. For any ECGs with subject safety concerns, two additional ECGs should 
be performed to confirm the safety finding. Clinically significant ECG findings prior to 
dosing with investigational treatment must be discussed with the Sponsor.
Clinically significant abnormalities should be recorded on the relevant section of the medical 
history/Current medical conditions/AE eCRF page as appropriate.
The eCRF will contain:
date and time of ECG
heart rate
PR interval
QT uncorrected
QTcF
QRS duration.
6.5.7
Pregnancy
Corporate Confidential Information
Pregnancy tests are required of all female subjects regardless of reported reproductive/ 
menopausal status.
Serum pregnancy tests will be performed at screening, baseline and at the end of the study. 
Atall other times urine pregnancy tests may be used.
If a urine pregnancy test is performed and is found to be positive, this will require 
immediateperforming a serum β-hCG. If positive, the Sponsor and Investigator will decide if 
discontinuation from the trial is required or whether study assessments can continue without 
compromising the patient’s safety.
When performed at screening and atbaseline, the result of this test must be received before 
the subject may be dosed.

Other safety assessments
6.5.8.1 PPD skin test or QuantiFeron test
A purified protein derivative (PPD) skin test will be performed and read at screening or within 
6months prior to randomization in order to evaluate theinfection with tuberculosis(TB). 
Thetest dose is bioequivalent to 5 tuberculin units (or as according to local standard practice) 
of standard PPD injected intra-dermally into usually the volar surface of the forearm. The site 
is cleansed and the PPD extract is then injected into the most superficial dermal layer of the 
skin. If given correctly, the injection should raise a small wheal of about 5 mm, which 
resolves within 10-15 minutes.
Because the reaction (induration) will take 48-72 hours to develop, the subject must return to 
the investigators’ site within that time for a proper evaluation of the test site. This will 
determine whether the subjects have had a significant reaction to the PPD test. A reaction is 
measured in millimeters of induration (hard swelling) at the site. A PPD skin induration 
≥5mm is interpreted as positive result.
Precautions against tuberculosis should be handled according to the best medical practice 
consistent to the local standards in each country with prior consultation with Novartis. 
Patients requiring administration of antibiotics against latent tuberculosis should complete 
their treatment and should be considered cured prior to being re-considered for entry into this 
study (consultation with Novartis must occur before allowing the patient to enter the study).
Based on the study site’s normal practice, QuantiFeron test may replace PPD skin test at 
screening. A positive QuantiFeron test at screening will exclude the subjects from the 
participation in the study.
T-SPOT or other types ELISPOT assays basedon interferon-gamma release may also be used 
for tuberculosis diagnosis as per local practice.
Results will be available as source data and willnot be recorded within the eCRF.
6.5.8.2 Infections
All occurrences of infections must be carefully monitored by the investigator. Significant 
findings, which meet the definition of infection, must be recorded in the Adverse Event eCRF.

Safety monitoring
7.1
Adverse events
An adverse event (AE) is any untoward medical occurrence (i.e., any unfavorable and 
unintended sign [including abnormal laboratory findings], symptom or disease) in a subject or 
clinical investigation subject.Therefore, an AE may or may not be temporally or causally 
associated with the use of a medicinal (investigational) product.
For all subjects who have signed informed consent and are entered into the study will have all 
adverse events occurring after informed consent is signedrecorded on the Adverse Event 
eCRF.
Pre-existing medical conditions/diseases (i.e.,Medical History(ies)) are considered AEs if 
they worsen after providing written informed consent. Abnormal laboratory values or test 
results constitute AEs only if they induce clinical signs or symptoms, or are considered 
clinically significant, or they require therapy.
The occurrence of adverse events should be sought by non-directive questioning of the subject 
at each visit during the study. Adverse events also may be detected when they are volunteered 
by the subject during or between visits or through physical examination, laboratory test, or 
other assessments.
Clinically significant abnormal laboratory values or test results should be identified through a 
review of values outside of normal ranges/clinically notable ranges, significant changes from 
baseline or the previous visit, or values which are considered to be non-typical in patientswith 
underlying disease. Investigators have the responsibility for managing the safety of individual 
subjectand identifying adverse events. Alert ranges for liver related eventsare included in 
Appendix 3.Adverse events must be recorded on the Adverse Events eCRF under the signs, 
symptoms or diagnosis associated with them, and accompanied by the following information:
1. the severity grade:
mild:
usually transient in nature and generally not interfering with normal 
activities
moderate:
sufficiently discomforting to interfere with normal activities
severe:
prevents normal activities
2. its relationship to thestudy treatment (no/yes), or indistinguishable
3. its duration (start and end dates) or if the event is ongoing an outcome of not 
recovered/not resolved should be reported
4. whether it constitutes a serious adverse event (SAE)
5. action taken regarding studytreatment
6. its duration (e.g.,start and end date)
7. whether it constitutes a serious adverse event (SAE)
8. action taken regarding studytreatment
9. whether other medication or therapies have been taken (concomitant medication/non-drug 
therapy)

10.its outcome.
An SAE is defined as any AE which meets any one of the following criteria:
is fatal or life-threatening
results in persistent or significant disability/incapacity
constitutes a congenital anomaly/birth defect
requires inpatient hospitalization or prolongation of existing hospitalization, unless 
hospitalization is for:
routine treatment or monitoring of the studied indication, not associated with any 
deterioration in condition, elective or pre-planned treatment for a pre-existing 
condition that isunrelated to the indication under study and has not worsened since 
signing the informed consent form
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, i.e.,defined as an event that jeopardizes the patient or may 
require medical or surgical intervention to prevent one of the outcomes listed above.
All malignant neoplasms will be assessed as serious under “medically significant” if other 
seriousness criteria are not met.
Unlike routine safety assessments, SAEs are monitored continuously and have special 
reporting requirements; see Section 7.2.
All adverse events should be treated appropriately. Treatment may include one or more of 
thefollowing: no action taken (i.e.,further observation only); study drug dosage 
adjusted/temporarily interrupted; study drug permanently discontinued due to this adverse 
event; concomitant medication given; non-drug therapy given. The action taken to treat the 
adverse event should be recorded on the Adverse Event eCRF.
Once an adverse event is detected, it should be followed until its resolution or until it is 
judged to be permanent, and assessment should be made at each visit (or more frequently, if 
necessary) of any changes in severity, the suspected relationship to the study drug, the 
interventions required to treat it, and the outcome.
Information about common side effects already known about the investigational drug can be 
found in the Investigator Brochure (IB) or will be communicated between IB updates in the 
form of Investigator Notifications. This information will be included in the informed consent 
and should be discussed with the subject during the study as needed.

7.2
Serious adverse event reporting
To ensure subjectsafety, every SAE, regardless of causality, occurring after the subjecthas 
provided informed consent and until 30 days after the last study visitmust be reported to 
Novartis within 24 hours of learning of its occurrence. Any SAEs experienced after the 
30days period should only be reported to Novartis if the investigator suspects a causal 
relationship to study treatment. 
Recurrent episodes, complications, or progression of the initial SAE must be reported as 
follow-up to the original episode, regardless of when the eventoccurs. This report must be 
submitted within 24 hours of the investigator receiving the follow-up information. An SAE 
that is considered completely unrelated to a previously reported one should be reported 
separately as a new event.
Information about all SAEs (either initial or follow up information)is collected and recorded 
on the paper Serious Adverse Event Report Form. The investigator must assess the 
relationship to study treatmentcomplete the SAE Report Form in English, and send the 
completed, signed form by fax within 24 hours after awarenessof the SAEto the local 
Novartis Drug Safety and Epidemiology Department. The telephone and fax number of the 
contact persons in the local department of Drug Safety and Epidemiology, specific to the site, 
are listed in the investigator folder provided to each site. The original copy of the SAE Report 
Form and the fax confirmation sheet must be kept with the case report form documentation at 
the study site.Follow-up information should be provided using a new paper SAE Report 
Form stating that this is a follow-up to apreviously reported SAE.
Follow-up information provided should describe whether the event has resolved or continues, 
if and how it was treated, whether the treatment code was broken or not and whether the 
subjectcontinued or withdrew from study participation. Each re-occurrence, complication, or 
progression of the original event should be reported as a follow-up to that event regardless of 
when it occurs.
If the SAE is not previously documented in the Investigator’s Brochure or Package Insert 
(new occurrence) and is thought to be related to the investigational treatment a Drug Safety 
and Epidemiology Department associate may urgently require further information from the 
investigator for Health Authority reporting. Novartis may need to issue an Investigator 
Notification (IN) to inform all investigators involved in any study with the same 
investigational treatment that this SAE has been reported.Suspected Unexpected Serious 
Adverse Reactions (SUSARs) will be collected and reported to the competent authorities and 
relevant ethics committees in accordance with EU Guidance 2011/C 172/01 or as per national 
regulatory requirements in participating countries.
7.3
Liver safety monitoring
To ensure subjectsafety and enhance reliability in determining the hepatotoxic potential of an 
investigational drug, a standardized process for identification, monitoring and evaluation of 
liver events has to be followed.
Liver events are divided into two categories:
Liver events of special interest (AESI) which consist of elevated liver function tests LFTs.


Novartis
Confidential
Page 92
Amended Protocol Version v07 Clean
Protocol No. CCFZ533X2203
Medically significant liver events which are considered as serious adverse events (SAEs) 
and which consist of marked elevations of LFTs.
Please refer to Table 15-1-Appendix 3forcomplete definitions of liver events.
Any liver event which meets the criteria for a “medically significant” event should follow the 
standard procedures for SAE reportingas described in Section 7.2.
Every liver event as definedin Table 15-1-Appendix 3should be followed up by the 
investigator or designated personnelat the trial site, as summarized below and detailed in 
Table 15-2-Appendix 3.
Repeating the LFT to confirm elevation as appropriate
Discontinuation of the investigational drug if appropriate
Hospitalization of the subjectif appropriate
A causality assessment of the liver event via exclusion of alternative causes (e.g., disease, 
co-medications)
An investigation of the liver event which needs to be followed until resolution.
These investigations can include serology tests, imaging and pathology assessments, 
hepatologist’s consultancy, based on investigator’s discretion. All follow-up information, and 
the procedures performed should be recorded as appropriate in the eCRF.
7.4
Pregnancy reporting
To ensure subjectsafety, each pregnancy occurring while the subjectis on study treatment

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, the field monitor will visit the site regularly to check the completeness of 
subjectrecords, the accuracy of entries on the eCRFs, the adherence to the protocol and to 
Good Clinical Practice, the progress of enrollment, and to ensure that study drug is being 
stored, dispensed, and accounted for according to specifications. Key study personnel must be 
available to assist the field monitor during these visits.
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 the recording of data that will be used for all primary and safety 
variables. Additional checks of the consistency of the source data with the eCRFs are 
performed according tothe study-specific monitoring plan. No information in source 
documents about the identity of the subjects will be disclosed.
8.2
Data collection
Designated investigator staff will enter the data required by the protocol into the Electronic 
Case Report Forms using fully validated software that conforms to 21 CFR Part 11 
requirements. Designated investigator site staff will not be given access to the EDC system 
until they have been trained. Automatic validation programs check for data discrepancies and, 
by generating appropriate error messages, allow the data to be confirmed or corrected before 
transfer of the data to Novartisorthe CRO working on behalf of Novartis. 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 a CD-ROM or paper copies of the 
subject data for archiving at the investigational site.
All data captured for this study will have an external originating source (either written or 
electronic), the eCRF is not considered as source.
In general the eCRF is not used as source. If the eCRF will be used as source (i.e.,no prior 
written or electronic record of data), then the protocol must clearly identify these data.

8.3
Database management andquality control
All data should be recorded, handled and stored in a way that allows its accurate reporting, 
interpretation and verification.
Novartis staff (or 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 who will make the correction to the database.
Concomitant medications entered into the database will be coded using the WHO Drug 
Reference List, which employs the Anatomical Therapeutic Chemical classification system. 
Medical history/current medical conditions and adverse events will be coded using the 
Medical dictionary for regulatory activities (MedDRA) terminology. At the conclusion of a 
non-IRT study, the occurrence of any emergency code breaks will be determined after return 
ofall code break reports and unused drug supplies to Novartis. Theoccurrence of any 
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.

Data for study drug administration (rescue medication) and concomitant therapies will be 
listed by treatment group andsubject.
9.4
Analysis of the primary variable(s)
The primary aimsof this study are to assess the safety of multiple intravenous infusionof
CFZ533 in patientswith pSS,and to investigate theeffect of multiple intravenous infusionof
CFZ533 based on ESSDAI at Week 13.Statistical analysis model will include data on the
ESSDAI from all timepointsup to Week 13and will provide thecomparison at Week 13.
Summaries of safety and tolerability data will beprovided as detailed inSection 9.5.2.
9.4.1
Variable(s)
The primary efficacy variable is the ESSDAI change from baseline.
9.4.2
Statistical model, hypothesis, and method of analysis
It is assumed that the ESSDAI will follow an approximate normal distribution. If this 
assumption appears to not be met, alternative statistical methods maybe applied. These will 
be described full in the Reporting and Analysis Plan (RAP).
The analysis of the data for primary variable will be conducted combining data from both 
Cohorts1 and 2. As a result, the three treatments under consideration would be Placebo 
(pooled), CFZ533 
 s.c.and CFZ533 
 i.v. A longitudinal model 
describing ESSDAIchange from baseline over time will be fitted for thecontrolled part of the 


Novartis

Amended Protocol Version v07 Clean
Protocol No. CCFZ533X2203
study (upto Week 13) with the following covariates: baseline ESSDAI, baseline prednisone 
dose, treatment(three as mentioned above), time as a continuous factor and a quadratic time 
effect, as well as a random intercept, a random slope and a random quadratic effect for subject. 
Anunstructured covariance matrix for the random effects will be fitted along with an 
independent error matrix. The change from baseline in ESSDAI at Week13(end of 
placebo-controlled period)will be estimated from the model for alltreatments and the 
difference between treatments to placebo will be presented along with 80% confidence 
intervals. Inference will be done in the frequentist framework.
The results from the primary analysis will be assessed against the following efficacy criteria
to support internal decision making(inference is done in the frequentist framework):
astatistically significant reductionin ESSDAI at Week 13in the CFZ533
 
i.v.group compared to placebo,at the one-sided 10% significance level, and
an estimated meanreduction in ESSDAI in the CFZ533
 i.v.group to be 
5points or greaterthan placebo.
The decrease of 5 points was chosen because it is in the range ofwhat was observed at 
week12 in a small open-label studywith rituximab(Meiners et al 2012).A positive sign of 
efficacywill be considered if both criteria are met.
ESSDAI data after Week 12 will be summarized using descriptive statistics and displayed 
graphically. ESSDAI data from cohort 3 will also be summarized using descriptive statistics. 
More detailswill be described in the RAP.
9.4.3
Handling of missing values/censoring/discontinuations
All subjects with a baseline ESSDAI and at least one post-baseline ESSDAI will be included 
in the primary analysis.The planned mixed effects model assumes that missing values are 
missing at random.The guidelines for subject discontinuation given in Section 5.5.10should 
ensure that the missingness mechanism is as close as possible to missing at random.
9.4.4
Supportive analyses
Other models than the one specified in Section 9.4.2may be considered: time would be 
modeled as categorical variableif the time course doesn’t appear to be quadratic.
Simpler covariances than the unstructured one may also be considered if needed.

Sample size calculation
Cohorts 1 and 2
With 24 patients in the analysisof the primary efficacy variable (16 in the CFZ533 group and
8 in the placebo group), the study would have around 1%chance of having a false-positive
result, i.e.,of meeting both the efficacy criteria when the true difference between CFZ533and
placebo is zero. Additionally the chances of meeting both the efficacy criteria remain below
10% for true differences between CFZ533and placebo of less than 2 points.
The study would have approximately 83% chance of meeting both the efficacy criteria, when
the true difference between CFZ533and placebo is 7 points.
In case the true difference between CFZ533 and placebo is only 5 points, thestudy would 
have approximately 51% chance of meeting both the efficacy criteria.These calculations 
assume that the primary efficacy variable, ESSDAI, follows a normaldistribution with a 
standard deviation of 5. This estimate of the standard deviation is based ona study of 
rituximab in patients with primary Sjögren’s syndrome(Meiners et al 2012) inwhich the 
observed standard deviation ranged from 5 at baseline to 3-7 post baseline.
With 24 patients(16 in the CFZ533 group and8 in the placebo group),the study would have 
around 38% power (resp. 70% power) to detect an increase of 30% (resp.42%) in the 
infection rate in the CFZ533 group, assuming a background rate of 5% on placebo.
The probabilities to observe a certain number of adverse events in each treatment arm, with 
this sample size, given assumed event rates, are given in Table 9-1

Cohort 3
With data from 10 patients in a treatment arm, the 90% confidence interval of
PKconcentrations at a given time-point is expected to be within 86% to 116% of the observed 
geometric mean with 90% coverage probability. A coefficient of variation of 20% was 
assumedin this calculation. With coefficients of variation of 30%, 40% and 50%, the 90% 
confidenceintervals are expected to be within 80% to 149%, 75% to 133%and 70%to 142% 
of theobserved geometric mean, respectively.
To allow for a drop-out rate of 15%, approximately 24 patients will be recruited into this cohort.
Sample size calculations were performed using NQuery 7.0 based on log-transformed
PKconcentrations.

Power for analysis of key secondary variables
Cohorts 1 and 2
With 24 patients (16 in the CFZ533 group and 8 in the placebo group),the study would have 
approximately 83%chance of detecting a decrease of 2 points in the ESSPRI, assuming a 
normal distributionwith a standard deviation of 2 for the variable. The standard deviation is 
based on Meiners et al (2012), in which the observed standard deviation ranged from 2.2 at 
baseline to 1.9-2.2 to post baseline.
Calculations have been made with NQuery 7.0.

10.2
Informed consent procedures
Eligible subjects may only be included in the study after providing written (witnessed, where 
required by law or regulation), IRB/IEC-approved informed consent. Ifincapable of doing so, 
after such consent has been provided by a legally acceptable representative of the subject. 
Incases where the subject’s representative gives consent, the subject should be informed 
about the study to the extent possible given his/her understanding. If the subject is capable of 
doing so, he/she should indicate assent by personally signing and dating the written informed 
consent document or a separate assent form.
Informed consent must be obtained before conducting any study-specific procedures (i.e.,all 
of the procedures described in the protocol). The process of obtaining informed consent 
should 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 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.
Women of child bearing potential should be informed that taking the study drug may involve 
unknown risks to the fetus if pregnancy were to occur during the study and agree that in order 
to participate in the study they must adhere to the contraception requirement for the duration 
of the study. If there is any question that the subject will not reliably comply, they should not 
be entered in the study.
In the event that Novartis wants to perform testing on the samples that are not described in 
this protocol, additional Institutional Review Board and/or Ethics Committee approval will be 
obtained.
10.3
Responsibilities of the investigator and IRB/IEC
Corporate Confidential Information
Before initiating a trial, the investigator/institution should obtain approval/favorable 
opinionfrom the Institutional Review Board/Independent Ethics Committee (IRB/IEC) for 
thetrial 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 Clinical Quality Assurance representatives, 
designated agents of Novartis, IRBs/IECs, and regulatory authorities as required. If an 


Novartis

inspection of the clinical site is requested by a regulatory authority, the investigator must 
inform Novartis immediately that this request has been made.
10.4
Publication of study protocol and results
Novartis assures that the key design elements of this protocol will be posted in a publicly 
accessible database such as clinicaltrials.gov. In addition, upon study completion and 
finalization of the study report the results of this trial will be either submitted for publication 
and/or posted in a publicly accessible database of clinical trial results.
11
Protocol adherence
This protocol defines the study objectives, the study procedures and the data to be collected 
on study participants. Additional assessments required to ensure safety of subjects should be 
administered as deemed necessary on a case by case basis. Under no circumstances should an 
investigator collect additional data or conduct any additional procedures for any research 
related purpose involving any investigational drugs.
Investigators ascertain they will apply due diligence to avoid protocol deviations. If the 
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/REB it cannot be implemented. All significant protocol 
deviations will be recorded and reported in the CSR.
11.1
Protocol Amendments
Any change or addition to the protocol can only be made in a written protocol amendmentthat 
must be approved by Novartis, Health Authorities where required, and the IRB/IEC. 
Onlyamendments that are required for subject safety may be implemented prior to 
IRB/IEC/REB approval. Notwithstanding the need for approval of formal protocol 
amendments, the investigator is expected to take any immediate action required for the safety 
of any subject included in this study, even if this action represents a deviation from the 
protocol. In such cases, Novartis should be notified of this action and the Health Authorities 
(where required) and the IRB/IEC/REB at the study site should be informed within 
10working days or less, if required by local regulation.

Introduction to RAPdocumentation
1.1
Scope
The RAP documents contain detailed information to aid the production of Statistics & 
Programming input into the Clinical Study Report (CSR) for trial “CCFZ533X2203”. 
Module 3 (M3) provides the description of the statistical methodologyused to analyze the 
data, Module 7(M7) details the presentation of the data, including shells of summary tables, 
figures and listings, and Module 8 (M8) contains programming specifications e.g. for derived 
variables and derived datasets, to support the creation of CSR outputs.
1.2
Changes to RAP documentation(M3)
Refer to corresponding guidances and Translational Sciences (TSc) RAP Addendum template 
for detailed information on the requirements of documenting changes to RAP documentation.
For the statistical methodology (M3), any major changes occurring before database lock to 
the statistical methodology should be reflected in the RAP M3 documentation via version 
control(new document version to be approved by the trial team as the original module.
Major changes include, but are not limited to, changes in protocol that affect study designand 
statistical methodology. 
Minor changes to the RAP M3 documentation can be captured e.g. by a study note to file / 
note in RAP Addendum or within the CSR itself. Minor changes include,but are not limited 
to, change in statistical model. Corrections of typographical errors or modification of spelling 
(from English to American, for example) do not need to be incorporated into the RAP M3 
documentation.

Study design and treatment
This is a double-blind followed by open-label, randomized, placebo-controlled, parallel-group, 
non-confirmatory study to assess the safety, tolerability, pharmacokinetics, and preliminary 
clinical efficacy of multiple doses of CFZ533 in the following Cohorts 1 and 2:
Cohort 1: 
 CFZ533 administered subcutaneously in patients with pSS, in a 
doubleblind and placebo-controlled fashion, followed by open-label treatment;
Cohort 2:  
 CFZ533 administered by intravenous infusion in patients with pSS, in
a double-blind and placebo-controlled fashion, followed by open label treatment.
These cohorts will be followed by an open label, randomized, parallel group, non-
confirmatory part of Cohort 3:

Corporate Confidential Information
Cohort 3 (patients with pSS):
In treatment arm 1 CFZ533 will be given at 
 s.c. weekly on 4 occasions (loading 
regimen), followed by 
 s.c. weekly on 9 occasions (maintenance regimen starting 
on study day 29). In treatment arm 2,the loading regimen will consist of a single i.v. dose 
of  
 CFZ533 (on study day 1), followed by  
 s.c. weekly on 12 occasions
(maintenance regimen starting on study day 8).
The study will randomize approximately 68 patients with primary Sjögren’s syndrome. In 
Cohorts 1 and 2, the randomization will be stratified by baseline intake of oral corticosteroids 
(yes/no). There will be no stratification in Cohort 3.
The study comprises three periods for Cohort 1 and Cohort 2:
1) placebo-controlled period(from Day 1, Week 1 to completion of pre-dose assessments on
Day 85, Week 13), during which 4 doses of CFZ533 or placebo will be administered on
topof the standard of care therapy, (e.g., low dose corticosteroid) that is necessary to treat 
pSS;
2) open-label period (from dosing on Day 85, Week 13 to completion of assessments on Day 
169, Week 25), when all patients will receive 4 doses of open-label CFZ533 treatment, 
and
3) follow-up period (Weeks 25 –32), when patients will be followed up without study
medication.
An illustration of the study design for Cohorts 1 and 2 is provided in Figure 2-1.

Cohort 3, comprises two periods, namely:
1. open-label treatment period (from dosing on Day 1, Week 1 to last dose and completionof 
assessments on Day 85, Week 13),
2. follow-up period (from Week 13 to Day 141/Week 21), when patients will be followedup 
for 8 weeks without study medication.
In the open label period, treatment arm 1 dosing starts with CFZ533 
 s.c. q1w for4 
weeks, whereas in treatment arm 2, dosing starts with CFZ533 
 i.v. on Day 1.In 
both arms maintenance dosing then continues with CFZ533 
 s.c. q1w for 4 weeks 
(treatment arm 1) or9 weeks (treatment arm 2).

Statistical methods for Pharmacokinetic (PK) parameters
6.1
Pharmacokinetic parameters
If data permits, the following pharmacokinetic parameters will be determined using the actual 
recorded sampling times and non-compartmental analysis: Cmax, Cmax,ss, Ctrough, 
Ctrough,ss and AUC’s from the CFZ533 plasma concentration-time data.Concentrations 
below the LLOQwill be treated as zero for PK parameter calculations. The linear trapezoidal 
rule will be used for AUC calculation. Regression analysis of the terminal plasma elimination 
phase for the determination of T1/2 will include at least 3 data points after Cmax (but not 
including Cmax). If the adjusted R2value of the regression analysis of the terminal phase is
less than 0.75, T1/2, AUCinf, Vz/F and CL/F will be excluded and indicated as missing
values.
6.2
Analysis of pharmacokinetics
Plasma CFZ533 concentration data will be listed by cohort, treatment, subject, and 
visit/sampling time point. Descriptive summary statistics will be provided by cohort, 
treatment and visit/sampling time point, including the frequency (n, %) of concentrations 
below the LLOQ and reported as zero. Summary statistics will include mean (arithmetic and

geometric), SD, CV (arithmetic and geometric), median, minimum and maximum. 
Concentrations below LLOQwill be treated as zeroin summary statistics. A geometric mean 
will not be reported if the dataset includes zero values.
Pharmacokinetic parameters will be listed by cohort, treatment and subject. Descriptive 
summary statistics will include mean (arithmetic and geometric), SD, and CV (arithmetic and 
geometric), median, minimum and maximum. An exception to this is Tmax where median, 
minimum and maximum will be presented.
. During any modeling of PK data, the broad principles outlined in theFDA
Guidance for Industry: Population Pharmacokinetics, will be followed.

Statistical methods for Pharmacodynamic (PD) parameters
7.1
Analysis of the primary variable
7.1.1
Statistical model, hypothesis, and method of analysis
The primary efficacy variable is the ESSDAI change from baseline.
It is assumed that the ESSDAI will follow an approximate normal distribution.If this 
assumption appears to not be met, alternative statistical methods maybe applied. For example, 
data may be log transformed with changes from baseline in the log transformed data being 
analyzed.
The analysis of the data for the primary variable from Cohorts 1 and 2 differs from that 
proposed in the protocol in that it will not be conducted combining placebo data from those 
two cohorts.Being in two separate consecutive cohorts, one s.c. and the other i.v., they are not 
now considered similar enough to combine. As a result, the active treatments under 
consideration, 
 areeach 
compared to their respective matching placebo treatments within each cohort.Cohort 3 simply 
compares two alternative loading regimes.
For each of cohorts 1 and 2, alongitudinal model describing ESSDAIchange from baseline 
over time will be fitted upto Week 13with the following fixed effect terms: baseline ESSDAI, 
treatmentgroup, visit, and interaction between treatment group and visit. In the first instance 
anunstructured variance-covariance matrix will be fitted;if there are issues with convergence 
then other variance-covariance matrices will be investigated. The change from baseline in 
ESSDAI at Week 13 (end of placebo-controlled period) will be estimated from the model. 
Inference will be done in the frequentist framework.
For Cohorts 1 and 2 the results from the primary analysis will be assessed against the 
following efficacy criteria:
astatistically significant reductionin ESSDAI at Week 13in the CFZ533
 
i.v. group compared to placebo,at the one-sided 10% significance level, and


an estimated meanreduction in ESSDAI in the CFZ533
 i.v. group to be 
5points or greater than placebo.

CCFZ533X2203
The decrease of 5 points was chosen because it is in the range of what was observed at 
week12 in a small open-label study with rituximab (Meiners et al 2012).A positive sign of 
efficacy will be considered if both criteria are met.
In Cohorts 1 and 2,ESSDAI data after Week 13, where there is no longer a placebo treatment,
will be examined similarly. It will also be summarized using descriptive statistics of both 
absolute values and changes from baseline and the raw data displayed graphicallyfor 
individual patients and for visit treatment means.Graphs will also be used to display modelled 
treatment effects over time.
ESSDAI data from Cohort 3 up to Week 13 and then to Week 21 will also be analyzed in a 
similar way to the data from each of Cohorts 1 and 2, but withtwo active treatment groups
instead of comparison with control. It will also be summarized with descriptive statisticsand 
plots similarly.
Handling of missing values/censoring/discontinuations
All subjects with a baseline ESSDAI and at least one post-baseline ESSDAI will be included 
in the primary analysis. The planned modelsassume that missing values are missing at 
random. The guidelines for subjectdiscontinuation provided in the protocol should ensure that 
the missingness mechanism isas close as possible to missing at random.The reasonableness 
of this assumption will be checked and if necessary further methods may be applied.
Supportive analysis
The Bayesian analyses proposed in the protocol for the interim analysis of Cohort 1 will serve 
as supportive to the main frequentist analysis abovewhen applied in a similar manner to 
Cohorts 1 and 2.
TwoBayesian posterior probabilities as follows will be calculated for Cohorts 1 and 2:
Pr (θCFZ533,13w-θ
placebo,13w <0 | data)
Pr (θCFZ533,13w-θ
placebo,13w <-5 | data)
where θ means change from baseline in ESSDAI at Week 13.
It is assumed that Y
ijt, the observed change from baseline in ESSDAI for subject i receiving
treatment j (CFZ533or placebo) at time t, follows a normal distribution N(θjt, σ
2),It is further 
assumed that θ
jtfollows a standard non-informative prior Normal distribution,p(θjt, σ
2) = 1/σ
2.
Thisstatistical model will be a repeated measures Bayesian analysis with baselineas a 
covariate using PROC MCMC. Example SAS code is provided in the RAP Module 8.
Estimates of the difference between CFZ533and placebo at each timepoint will be derived
from this model and presented together with 95% credible intervals.
If required, further frequentist supportive analyses will attempt to model the time effect to 
better describe changes over time. If so,the model may include the following covariates: 
baseline, treatment, time, treatment by time interaction, treatment by time squaredinteraction, 
as well as a random intercept and a random slope for each patient. Time may be modeled as a 
continuous variable. The model may be simplified if there are problems with convergence, 
including a simpler variance-covariance matrix. The treatment by time squaredinteraction 
will be included if it improves the fit.
