Glossary of terms 
Assessment 
A procedure used to generate data required by the study. 
Baseline 
Assessments taken during Visit 2/Randomization 
Control drug 
A study drug used as a comparator to reduce assessment bias, 
preserve blinding of investigational drug, assess internal study 
validity, and/or evaluate comparative effects of the investigational 
drug. 
Enrollment 
Point/time of patient entry into the study; the point at which 
informed consent (ICF) must be obtained (i.e. prior to starting any 
of the procedures described in the protocol) 
Investigational drug 
The study drug whose properties are being tested in the study; 
this definition is consistent with US 21CFR 312.3 and is 
synonymous with “investigational new drug.” 
Medication number 
A unique identifier on the label of each medication package in 
studies that dispense medication using an Interactive Response 
Technology (IRT) system. 
Patient number 
A number assigned to each patient who enrolls in the study. 
When combined with the center number, a unique identifier is 
created for each patient in the study. 
Period 
A minor subdivision of the study timeline; divides phases into 
smaller functional segments such as screening, baseline, 
treatment, titration, washout, etc. 
Premature patient withdrawal 
Point/time when the patient exits from the study prior to the 
planned completion of all study drug administration and/or 
assessments; at this time all study drug administration is 
discontinued and no further assessments are planned. 
Randomization number 
A unique identifier assigned to each randomized patient, 
corresponding to a specific treatment arm assignment. 
Stage 
A major subdivision of the study timeline; begins and ends with 
major study milestones such as enrollment, randomization, 
completion of treatment, etc. 
Stop study participation 
Point/time at which the patient came in for a final evaluation visit 
or when study drug was discontinued whichever is later. 
Study drug 
Any drug administered to the patient as part of the required study 
procedures; includes investigational drug and any control drugs. 
Study drug discontinuation 
Point/time when patient permanently stops taking study drug for 
any reason; may or may not also be the point/time of premature 
patient withdrawal. 
Variable 
Information used in the data analysis; derived directly or indirectly 
from data collected using specified assessments at specified time 
points.

Amendment 3 
Amendment rationale 
The main purpose of this protocol amendment is to reflect changes in the result reporting 
strategy and remove the CSR (and accompanying database lock) previously planned at week 
12. Also, provided additional patient consent is given, samples taken for adalimumab trough 
concentration and ADA assessment may now be used 
 
instead of being discarded. In addition minor editorial corrections and clarifications were made 
throughout the protocol. 
 
Rationale for removing Week 12 CSR 
The purpose of this protocol amendment is to reflect a modified the study reporting strategy. 
With this current approach, a single CSR is now planned at the end of the study and will cover 
objectives for all study periods, including the primary endpoint analysis at week 12, the head- 
to-head comparison of GP2017 to Humira in study period 1 as well as the switching to or 
continuation on GP2017 of all patients in study period 2. Consequently, the Week 12 CSR is 
no longer required and the study team will remain blinded until the end of the study. 
 
Rationale for using remaining samples for future research and additional 
biomarker assessments 
The purpose of this protocol amendment is to allow for use of already collected serum samples 
that are left over after the adalimumab trough concentration and ADA assessments for 
additional research. 
 
 
 
 
 
 
 
 
Study status 
All patients have been randomized into the study.

Study design 
This study has a parallel-group, randomized, double-blind design and it is 
planned to randomize approximately 308 patients with moderate to 
severe active RA at approximately 110 study sites worldwide. 
A screening period of up to 4 weeks will be used to assess patient´s 
eligibility. All patients must be on stable dose of MTX at least 4 weeks 
prior to randomization and continue throughout the study on this dose. 
At the baseline visit (Day 1, Visit 2); eligible patients will be randomized 
using a 1:1 ratio to one of the two treatment arms: GP2017 or US-licensed 
Humira®. Randomized patients will enter a 24-week treatment phase 
Study Period 1 and shall be treated with either GP2017 or US-licensed 
Humira®. Study drug administration will be performed at the site by 
designated unblinded personnel. At Week 24 all patients will be evaluated 
for their DAS28-CRP response. Patients who did not show at least a 
moderate DAS28-CRP response will have their final assessment at Week 
24 and will not continue in the study. 
Irrespective of their treatment during Study Period 1, all patients with at 
least a moderate response at Week 24 by DAS28-CRP score, will be 
switched to or continue with subcutaneous injection of GP2017 from 
Week 24 up to Week 46. End of Study (EoS) Visit will be performed at 
Week 48. 
In Study Period 2, all patients will self-administer GP2017 injections. At 
Week 24 (Visit 14), appropriate training for administration of GP2017 will 
be   provided   and   first   self-administration   will   be   done   under the 
supervision of designated unblinded study personnel at the study site.

Introduction 
1.1 
Background 
The development of GP2017 aims for a marketing authorization as a biosimilar product to 
Humira® according to the guidelines and legal framework of the European Medicines Agency 
(EMA) and those of the Food & Drug Administration (FDA). Marketing authorization is also 
planned to be sought in further countries and geographic regions. 
A biosimilar is a biological medicinal product that contains a version of the active substance of 
an already authorized biological medicinal product (the reference product) with demonstrated 
similarity in physicochemical characteristics, biological activity, efficacy and safety, based on 
a comprehensive comparability exercise (Weise et al 2011; Schneider 2013). It is intended to 
be used at the same dose(s) and dosing regimen(s) to treat the same disease(s) as the reference 
product. The development and commercialization of biosimilars can help address unmet 
medical needs by improving access to well-established therapeutic interventions while 
improving healthcare affordability (McCamish and Woollett 2012). 
Humira® (adalimumab; US: AbbVie Inc., EU: AbbVie Ltd.) is a “fully human” monoclonal 
antibody that binds specifically to Tumor Necrosis Factor alpha (TNF-α), a pleiotropic 
inflammatory cytokine, and thus blocks its interaction with the p55 and p75 cell-surface TNF 
receptors. 
Humira® received licensure in the US in 2002 and marketing authorization in the EU in 2003. 
It is indicated for the treatment of rheumatoid arthritis (RA), polyarticular juvenile idiopathic 
arthritis, psoriatic arthritis (PsA), ankylosing spondylitis, ulcerative colitis, Crohn’s disease, 
pediatric Crohn´s disease, plaque psoriasis, hidradenitis suppurativa and uveitis. Only in EU it 
is also indicated for enthesitis-related arthritis, axial spondyloarthritis without radiographic 
evidence of ankylosing spondylitis and pediatric plaque psoriasis. For information regarding 
the efficacy and safety of this product please refer to the Humira Prescribing Information (USPI) 
or the European Summary of Product Characteristics (EU SmPC). 
 
 
 
 
 
 
GP2017 has also been shown to be similar to EU-authorized and US-licensed Humira® at the 
functional level in vitro: GP2017 and Humira® bind to TNFα with similar kinetics and affinity. 
The binding affinities to all relevant Fc receptors (FcR), like FcγRI, FcγRII, FcγRIII and the 
neonatal Fc receptor (FcRn) are similar between GP2017 and Humira®, and the biological 
functionality in terms of neutralization of TNFα and induction of antibody-dependent cellular 
cytotoxicity and complement-dependent cytotoxicity are also similar. 
In summary, comparative physicochemical and biological characterization in terms of target 
and Fc-receptor binding affinities and in vitro functionality, showed a good degree of similarity

between GP2017 and Humira® (US-licensed and EU-authorized), and non-clinical studies 
demonstrated similar bioavailability, pharmacokinetics (PK), pharmacodynamics, safety and 
tolerability for GP2017 and EU-authorized Humira®. A comprehensive background to all 
previous preclinical studies and development plan with GP2017 is available in the Investigators 
Brochure (IB -GP2017 Investigators Brochure). 
First clinical data in humans on GP2017 have become available. In total, 73 healthy volunteers 
received a single injection of GP2017. The results of this first trial have not revealed any 
difference in the safety and immunogenicity profile of GP2017 and US-licensed or EU- 
authorized Humira®. In this study similar pharmacokinetic, safety and immunogenicity profiles 
were demonstrated between GP2017 and US-licensed Humira®. GP2017 is currently being 
investigated in a confirmatory efficacy and safety clinical trial in patients with moderate to 
severe chronic plaque psoriasis. 
GP2017 is developed to be provided as pre-filled syringe as well as a pre-filled pen for 
subcutaneous (s.c.) administration and in the same strength for adults as the originator product 
(40 mg/0.8 ml). The development of GP2017 aims to claim all indications currently approved 
for Humira®. 
1.2 
Purpose 
The purpose of this study is to demonstrate similar efficacy and to compare safety and 
immunogenicity of GP2017 and US-licensed Humira® in patients with moderate to severe RA 
with inadequate response to Methotrexate (MTX) with or without other Disease modifying anti- 
rheumatic drugs (DMARDs). This treatment schema follows the EULAR/ACR 
recommendations for management of RA with synthetic and biological DMARDs (Smolen et 
al 2014(a)). 
This study is part of the clinical development program of GP2017 and aims to support the 
worldwide registration of GP2017 as a biosimilar to Humira®.

Investigational plan 
3.1 
Study design 
This study has a parallel-group, randomized, double-blind design and it is planned to randomize 
approximately 308 patients with moderate to severe active RA at approximately 110 study sites 
worldwide. A screening period of up to 4 weeks will be used to assess patient´s eligibility. All 
patients must be on a stable dose of MTX at least 4 weeks prior to randomization and continue 
throughout the study on this dose. 
At the baseline visit (Day 1, Visit 2); eligible patients will be randomized using a 1:1 ratio to 
one of the two treatment arms: GP2017 or US-licensed Humira®. Randomized patients will 
enter a 24-week treatment phase Study Period 1 and shall be treated with s.c. injection of either 
GP2017 or US-licensed Humira®. Study drug administration will be performed at the site by 
designated unblinded personnel. At Week 24 all patients will be evaluated for their DAS28- 
CRP response. Patients who did not show at least a moderate DAS28-CRP response will have 
their final assessment at Week 24 and will not continue in the study. 
Irrespective of their treatment during Study Period 1, all patients with at least a moderate 
response at Week 24 by DAS28-CRP score, will be switched to or continue with subcutaneous 
injection of GP2017 from Week 24 up to Week 46. EoS Visit will be performed at Week 48. 
In Study Period 2, all patients will self-administer GP2017 injections. At Week 24 (Visit 14), 
appropriate training for administration of GP2017 will be provided and first self-administration 
will be done under the supervision of designated unblinded study personnel at the study site. 
Afterwards, the patient will receive written Instructions for Use (IFU) of GP2017 and will self- 
administer GP2017 injections.

3.2 
Rationale of study design 
GP2017 is developed to claim the same indications as currently approved for Humira®. This 
double-blind, randomized, comparator drug controlled, parallel-group design is aligned with 
the key features of similar trials investigating adalimumab with various conventional synthetic 
therapies for RA. 
Current recommendations for first line treatment of RA are the established conventional 
synthetic DMARDs such as MTX. Anti-TNFα agents are first line biologics used in 
conventional synthetic DMARD failure patients. 
The study design resembles the ARMADA study reported by Weinblatt et al 2003. Patients 
with active RA despite previous MTX treatment were included in the ARMADA study. Patients 
were treated with Humira®, while continuing on stable dose of MTX until the end of study. The 
primary endpoint was ACR20 response rate, which was demonstrated to be significantly higher 
when adding Humira® to MTX than MTX treatment alone. However the primary endpoint in 
the current study is different to the ARMADA trial. DAS28-CRP score was not yet fully 
established and validated at the time of the ARMADA study. Later, several studies investigated 
the clinical relevance of DAS28-CRP parameter to monitor the disease activity and response to 
treatment and established its validity (e.g. OPTIMA, CONCERTO, HIT HARD, ReAct studies) 
(Smolen et al 2014(b), Burmester et al 2015, Detert et al 2013, Burmester et al 2007). 
Consequently, Committee for Medicinal Products for Human Use (CHMP) draft guideline on 
clinical investigation of medicinal products other than NSAIDs for treatment of RA 
(CPMP/EWP/556/95 Rev. 2) recommends DAS28 score as a validated efficacy measure. This 
score represents a continuous measure of disease activity and is considered to be more sensitive 
than a categorical endpoint, such as ACR response rate. DAS28 score provides thresholds for 
disease activity for which a patient could be classified as having achieved remission, or as a

good or moderate responder. DAS28 score is now well established in the clinical practice as a 
parameter to evaluate disease activity and activity changes while on DMARD treatment and 
will be used for primary endpoint evaluation in this study. DAS28 score is calculated using 
either CRP or ESR as a parameter of inflammation. CRP is less affected by confounding factors 
such as age, gender and measures more short-term inflammation than ESR (Matsui et al 2007). 
DAS28-CRP score is also considered to be more sensitive and less variable when compared to 
DAS28-ESR score (Matsui et al 2007, Wells et al 2009). Therefore DAS28-CRP is prioritized 
above DAS28-ESR in this study for the primary endpoint. 
According to EULAR/ACR guidelines (Smolen et al 2014(a)) for the management of RA the 
improvement should be assessed 3 months after initiation of new treatment, meaning a reduction 
of disease activity from high to at least moderate should be seen. The maximum efficacy of new 
treatment (low disease activity or remission) should generally be achieved 6 months after the 
therapy initiation. 
Therefore, in this double-blind study the primary endpoint of change in DAS28-CRP from 
baseline will be evaluated at Week 12. This will allow for the comparison of similar efficacy 
and safety of GP2017 and US-licensed Humira®. The overall parallel double-blind treatment 
with GP2017 or US-licensed Humira® will continue until Week 24. Afterwards, patients with 
at least moderate DAS28-CRP response will continue on or will be switched to self-administer 
GP2017. Data on long-term (48 weeks) safety, efficacy and immunogenicity of GP2017 as well 
as safety, efficacy and immunogenicity of the switch from US-licensed Humira® to GP2017 
will be generated. 
Approximately 30 – 40% of patients fail to respond to anti-TNFα or lose response over time 
(Papagoras et al 2010). The ability to predict those RA patients, who will respond to 
adalimumab treatment, would prevent accumulation of inflammatory joint and bone damage 
and avoid unnecessary drug exposure in patients, who will be unlikely to respond to 
adalimumab treatment. Biomarkers are objectively measured and evaluated indicators of 
normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic 
intervention (Atkinson et al 2001). 
 
 
 
 
 
 
 
 
3.3 
Rationale of dose/regimen, duration of treatment 
GP2017 is developed as a biosimilar to Humira®. Therefore the dose and route of administration 
are chosen according to the current label of Humira® for the therapy of active moderate to severe 
RA with background MTX treatment.

3.4 
Rationale for choice of comparator 
GP2017 is developed as a biosimilar to Humira®. The results of the phase I PK trial (GP17- 
101) showed that PK parameters of GP2017 and US-licensed Humira® met bioequivalence 
criteria. No clinically relevant differences concerning safety and immunogenicity were 
observed between the products. Consequently, US-licensed Humira® is chosen as the 
comparator in this clinical study to assess similar efficacy, safety and immunogenicity of 
GP2017. 
 
3.5 
Purpose and timing of interim analyses 
 
No interim analysis is planned. For further details on the analysis refer to Data Anaysis (Section 
9). 
 
3.6 
Risks and benefits 
Comparative physicochemical and biological characterization in terms of target and Fc-receptor 
binding affinities and in vitro functionality, showed a high degree of similarity between GP2017 
and Humira® (US-licensed and EU-authorized) and non-clinical studies demonstrated similar 
bioavailability, pharmacodynamics potency and tolerability for GP2017 and EU-authorized 
Humira®. A human pharmacokinetic study confirmed the bioequivalence of GP2017 and US- 
licensed Humira®. In total, 73 healthy volunteers received a single injection of GP2017. The 
results of this trial have not revealed any difference in the safety and immunogenicity profile of 
GP2017 and US-licensed or EU-authorized Humira®. Furthermore, a confirmatory efficacy and 
safety clinical trial with GP2017 in patients with moderate to severe chronic plaque psoriasis is 
currently ongoing. Safety data from this trial undergo regular Data Monitoring Committee 
(DMC) reviews and no concerns have been observed till date. Consequently, the efficacy and 
safety of GP2017 in patients with active RA is expected to be similar to that of US-licensed 
Humira®, the favorable risk-benefit ratio of which has been established in a wide range of 
clinical studies and by a substantial amount of post-marketing experience. All patients in the 
study will thereby receive active therapy following the approved dosing schedule for US- 
licensed Humira® with similar expectations for benefits. 
Given the expected similarity between GP2017 and US-licensed Humira®, the contraindications, 
precautions and warnings that are summarized in the originator product’s Humira Prescribing 
Information (USPI) should also apply to GP2017. 
One of the potential risks associated with any biopharmaceutical product is the induction of an 
immunogenic response and therefore assessment of anti-drug antibodies is an essential part of 
the study procedures. 
Compliance with the eligibility criteria as well as regular assessments of disease activity and 
clinical status ensure that safety is monitored closely and that both, patient and investigator have 
the opportunity to assess, if the continued participation in the study is to the patient’s benefit. If 
the patient’s participation is deemed not to be of benefit, the patient can exit the study at any 
time.

Population 
The study population will consist of male and female patients who are at least 18 years of age 
with active moderate to severe RA who failed previous treatment with MTX with or without 
other DMARDs. RA diagnosis must be established according to the ACR 1987 or revised 
ACR/EULAR 2010 criteria (Aletaha et al 2010) with a disease duration of ≥ 6 months, and with 
disease activity defined as DAS28-CRP score ≥3.2 at screening. Patients must be on a stable 
MTX dose for at least 4 weeks prior to baseline (randomization) and should continue on this 
stable dose throughout the study. The selection of the population is based on the EULAR/ACR 
recommendations (Smolen et al 2014(a)) for management of RA and CHMP draft guideline on 
clinical investigation of medicinal products other than NSAIDs for treatment of RA. 
The study is planned to randomize approximately 308 patients in approximately 110 centers 
worldwide. Patients that drop out after they have been randomized will not be replaced. A 
screen failure rate of 30% and a post-randomization dropout rate of 20% are anticipated. If the 
screen failure rate appears to be higher than expected, more patients will be screened. Screening 
will stop when the target number of randomized patients is anticipated. All patients in screening 
at that point of time will remain eligible for randomization.

• Group 2: US-licensed Humira®: s.c. injection of 40 mg/0.8 ml from Day 1 (Visit 2) to 
Week 22 (Visit 13) and then switched to GP2017 from Week 24 (Visit 14) until Week 46 
 
Study Period 1 (baseline - Week 24) 
Patients will receive doses of GP2017 or US-licensed Humira® every other week during their 
visits at the study site in a blinded fashion. The dosage and frequency will not be changed. 
 
Study Period 2 (Week 24 - Week 48) 
At Week 24 (Visit 14) all patients with at least moderate DAS28-CRP response, as defined by 
EULAR response criteria (see Table 6-3) will continue or will be switched to GP2017. The 
dosage and frequency will not be changed. 
In Study Period 2, all patients will self-administer GP2017 injections. At Week 24 (Visit 14) 
after appropriate training, patient will self-administer GP2017 under the supervision of 
qualified study personnel at study site. After being assessed as proficient at self-administration, 
the patient will receive written IFU for GP2017 and will continue to self-administer GP2017 
injections. However, if the unblinded study team member concludes at the Visit 14 (Week 24) 
that the patient cannot perform self-administration as per study protocol and needs further 
training the patient should be invited back to the site for further training until deemed proficient. 
Patients not achieving at least a moderate response will have their final assessment at Week 24 
(as per assessment schedule defined for EoS/ Visit 16) and will not continue in the study. 
 
5.3 
Treatment assignment 
At Visit 2, all eligible patients will be randomized via the Interactive Response Technology 
(IRT) system to one of the treatment arms. The investigator or his/her delegate will contact the 
IRT system and confirm that the patient fulfills all the inclusion/exclusion criteria. The IRT 
system will assign a randomization number to the patient, which will be used to link the patient 
to a treatment arm and will specify a unique medication number for the first package of study 
drug to be dispensed to the patient. 
The randomization numbers will be generated using the following procedure to ensure that 
treatment assignment is unbiased and concealed from patients and investigator staff. The 
randomization list will be produced by the IRT system provider (or by an independent provider) 
using a validated system that automates the random assignment of patient numbers to 
randomization numbers. These randomization numbers are linked to the different treatment 
arms, which in turn are linked to medication numbers. A separate medication randomization list 
will be produced using a validated system that automates the random assignment of medication 
numbers to medication packs containing each of the study drugs. 
Randomization will be stratified at baseline (Visit 2) by region (Americas and RoW), body 
weight and prior therapy. The stratification ensures balanced allocation of patients to treatment 
groups within the strata. The strata for body weight will be “body weight < 80 kg” or “body 
weight ≥ 80 kg”. The strata for prior RA therapy will be “prior treatment with MTX only”,

“prior treatment with other conventional synthetic DMARDs”, or “prior treatment with biologic 
DMARDs”. Stratification will occur at Visit 2 using the body weight assessed at Visit 2. 
 
5.4 
Treatment blinding 
The study drug cannot be blinded due to differences in primary packaging. To maintain the 
double-blind design of Study Period 1 it is necessary to involve unblinded staff at the study site 
for handling and administration of the study drug. During Study Period 1, unblinded 
investigational staff will receive, store, dispense, collect used IMP and during Study Period 2 
also assist patients with self-administration but must not perform any assessments. Measures 
(blindfolding, using a screen or asking the patient to look away) shall be taken to blind the 
patient during IMP administration in Study Period 1. Blinded site staff will not have any contact 
with IMP. 
All data will be collected fully blinded until the end of the trial with regard to treatment 
allocation during study period 1. 
Patients, blinded investigator staff and persons performing the assessments or being responsible 
for patient´s treatments will remain blinded to the Study Period 1 treatment from the time of 
randomization until end of study. Randomization data, including any documentation identifying 
the treatment allocation, are kept strictly confidential until the time of unblinding with the 
following exceptions: unblinded staff at the site and staff of the sponsor or delegated Contract 
Research Organization (CRO) responsible for study drug management including unblinded 
monitors. 
Unblinding will only occur in the case of patient emergencies (see Section 5.5.10) and at the 
time of the database lock for analyses.

Treating the patient 
5.5.1 
Patient numbering 
Each patient is uniquely identified in the study by a combination of his/her center number and 
patient number. Upon signing the ICF, the patient is assigned a unique patient number by the 
investigator. The unique patient number is a combination of the corresponding site number 
followed by a consecutive screening number at that site. Once assigned to a patient, the unique 
patient number will not be reused. 
If the patient fails to be randomized, the IRT system must be notified about the reason for 
screening failure. Patients can be re-screened once. For a patient to be re-screened, the patient 
must re-consent, a new patient number has to be assigned and all screening assessments have 
to be repeated. Screening log should be completed for all patients. 
 
5.5.2 
Dispensing the study drug 
Each study site will be supplied with study drug in open-label secondary packaging. 
Each medication kit will be labelled with a 2-part tear-off label. A unique medication number 
is printed on each part of this label, which corresponds to one of the treatments. For each visit,

the IRT system will allocate treatment drug to be dispensed/administered to the patient by 
providing the respective medication numbers to the unblinded site staff. Immediately before 
administration/ dispensing the package to the patient, unblinded site staff will detach the tear- 
off part of the label from the packaging and affix it to the source document (Drug Label Form) 
for that patient’s unique patient number. 
 
5.5.3 
Study drug supply, handling and storage 
Study drugs 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 designated unblinded site staff has 
access. Upon receipt, all study drugs should be stored according to the instructions specified on 
the drug labels. Clinical supplies are to be administered/dispensed only in accordance with the 
protocol. 
Any technical complaint about the study drug needs to reported to the sponsor within 24 hours 
of identification of the defect (for details refer to the study drug handling manual). Technical 
complaints are complaints about an optical, organoleptic, qualitative, quantitative, mechanical 
or functional defect of a pharmaceutical product or medical device. This may include: 
• Any fault of quality and/or effectiveness e.g. particles 
• Any fault of the containers and outer packages e.g. surface imperfection, container 
leakage, broken syringe/plunger, missing contents, device malfunction 
• Any fault of the labeling e.g. missing or illegible label 
• Any falsification of the medicinal product or device e.g. suspected product mix-up, or 
tampering. 
For reporting of AEs caused by the defect (if applicable) refer to Section 7. 
IMP handling manual provided to the site will contain information about storage conditions on 
site. In addition, site staff will verbally instruct the patient on transport and storage, and provide 
them with written patient instructions for use during the self-administration period. Medication 
labels will be in the local language and comply with the legal requirements of each country. 
They will include storage conditions for the drug, but no information about the patient. 
The unblinded site staff must ensure an accurate record of the shipment and administration/ 
dispensing of study drug in the drug accountability form. Monitoring of drug accountability 
will be performed by the unblinded monitor during site visits and at the completion of the trial. 
Patients will be asked to return all unused study drug and packaging at the end of the study or 
at the time of study drug discontinuation. 
At the conclusion of the study, and as appropriate during the course of the study, the site will 
destroy locally or return all unused study drug, packaging, drug labels to the designated depot 
as per instructions provided by the sponsor. A copy of the completed drug accountability ledger 
will be returned as instructed by the sponsor or delegated CRO.

5.5.4 
Instructions for prescribing and administering the study drug 
Both study treatments (GP2017 and US-licensed Humira®) are provided in pre-filled syringes 
(40mg/0.8mL) for subcutaneous use. For all administrations, one pre-filled syringe of the 
respective study treatment is to be given at visits as described in Table 6-1. 
All study treatment kits will be assigned to the patient using the IRT system and these would 
be recorded in the IRT system and the electronic Case Report Form (eCRF). 
The first study treatment administration will occur following randomization at Day1/Visit 2 
(Baseline) and after all scheduled study assessments have been performed, including 
confirmation of defined in- and exclusion criteria, and only after the scheduled blood samples 
have been drawn (see Table 6-1). 
During Study Period 1, a total of twelve GP2017 or US-licensed Humira® injections will be 
administered from Randomization on Day 1/Visit 2 to Week 22/Visit 13. Measures shall be 
taken to blind the patient during IMP administration. 
During Study Period 2, a total of twelve GP2017 injections from Week 24/ Visit 14 until Week 
46 will be administered. The last study visit will be performed at Week 48. 
At study visits, when pre-dose blood samples have to be drawn (see Table 6-1) GP2017 and 
US-licensed Humira® will be administered to the patient only after the blood samples have been 
taken. 
At each visit, all study assessments, including the completion of HAQ-DI should be completed 
prior to the administration of study treatment as described in Table 6-1 and Section 6.4.7. 
All dates of injections given to the patient during the study must be recorded on the Dosage 
Administration Record eCRF. 
All doses of study treatment will be administered at the study site until Week 24. At this Visit 
14 (Week 24) a patient eligible per protocol to continue in the study will be trained how to self- 
administer the IMP by self-administering one GP2017 injection at the site under the supervision 
of the unblinded qualified study personnel. If the patient is assessed as proficient at self- 
administration, the patient will receive IFU and 5 GP2017 pre-filled syringes for self- 
administration every other week until protocol Visit 15 (Week 36). However, if the unblinded 
team member concludes at the Visit 14 (Week 24) that the patient cannot perform self- 
administration as per the study protocol and needs further training the patient should be invited 
back to the site for further training until deemed proficient. In this case syringes assigned to the 
patient may continue to be stored at the site. At Visit 15 (Week 36), a patient will undergo all 
assessments as defined in the protocol, will perform a self-administration under supervision of 
unblinded site personnel at the site and subsequently will receive 5 pre-filled syringes with 
GP2017 for self-administration. Last self-administration will be done at Week 46. At Week 48, 
defined as EoS Visit, a patient will undergo all assessments as defined in the protocol. All 
unused syringes should be brought back to the site for the purpose of drug accountability. 
All injections administered to the patient and all changes during the study must be recorded on 
the Dosage Administration Record CRF (eCRF).

The investigator or designated staff will instruct the patient on how to self-administer the study 
drug at the start of Study Period 2, and provide the patient with written instructions for use on 
study drug administration. The patient will receive a diary booklet to document the self- 
administration dates. All study administration details must be checked by site personnel and 
should then be transcribed from the patient diary into the eCRF at each visit in Study Period 2. 
The investigator should promote compliance by instructing the patient to administer the study 
drug exactly as prescribed and by stating that compliance is necessary for the patient’s safety 
and the validity of the study. The patient should be instructed to contact the investigator if he/she 
is unable for any reason to attend the scheduled study visit or administer the study drug as 
prescribed. 
 
5.5.5 
Permitted study drug interruptions 
Study drug interruptions or missed injections are generally not permitted. 
It is possible for the investigator to interrupt study treatment for one or more doses when the 
patient is suffering from an adverse event that in the opinion of the investigator needs to be 
sufficiently resolved before study drug can be resumed. 
These interruptions/missed injections must be recorded on the Dosage Administration Record 
CRF (eCRF). 
 
5.5.6 
Rescue medication 
As all other RA treatments are prohibited per protocol, therefore a use of rescue medication for 
RA would lead to discontinuation of the patient from study treatment and withdrawal from the 
study. If any rescue medication for RA is used, this must be recorded in the (e)CRF. 
 
5.5.7 
Background and Concomitant treatment 
 
5.5.7.1 
Background treatment of RA 
Methotrexate 
Patients have to be treated with MTX for at least 3 months. Dose of MTX ( ≥ 10 mg/week to ≤ 
25 mg/week) must be stable for at least 4 weeks before baseline (randomization). Dose should 
be maintained stable throughout the study participation with the same route of administration. 
The maximum tolerated dose is defined by the investigator for each particular patient based on 
individual circumstances as the maximum dose that was tolerated by the patient. 
If MTX is administered by a subcutaneous administration, then the injection site must not 
coincide with US-licensed Humira® or GP2017 injection sites at the given administration time. 
Dose adjustments of MTX are not permitted unless patient has developed MTX-related toxicity. 
MTX discontinuation will lead to patient´s withdrawal from both treatment and the study. 
Note: MTX affects gametogenesis during the period of its administration and has been reported 
to cause fetal death and/or congenital anomalies as described in MTX label. Patients and their 
partners should have been advised by the investigator to this effect at the initiation of MTX

therapy. Conceiving a child should be avoided for both male and female participants in the 
study during the period of MTX administration, and an appropriate level of contraception 
should be maintained in accordance with the local MTX label safety recommendations. A 
decision about the eventual suspension or change of the contraception should be made only 
under guidance from the treating physician, and in accordance to the recommendations of the 
local MTX label. 
 
Folic Acid 
Patients should have received folic acid or equivalent from at least 4 weeks prior randomization 
at a stable dose (≥ 5 mg per week) and during the trial to minimize the likelihood of MTX 
associated toxicity. Folic acid supplementation should not be taken on the day of MTX intake, 
but preferably one day after MTX administration. 
 
5.5.7.2 
Concomitant treatments 
The investigator should instruct the patient to notify the study site about any new treatments 
(including over-the-counter drugs, supplements, calcium and vitamins) that he/she takes after 
signing 
the 
ICF. 
Concomitant 
therapy 
with 
NSAIDs/COX-2 
inhibitors/ 
paracetamol/acetaminophen/low strength opioids and oral corticosteroids and all other 
concomitant medications (including any treatments started during the screening period) and 
significant non-drug therapies (including physical therapy and blood transfusions) will be 
recorded on the appropriate eCRF page. While conventional synthetic DMARDs and biologics 
received before study entry have to be specified without time limitation in details on a separate 
eCRF page (previous RA related therapies), all other past medications and significant non-drug 
therapies not related to the study indication have only to be recorded if given 6 months prior to 
signing ICF. 
Patients will be informed that they are not permitted to take any additional medication, 
including over-the-counter preparations, without first consulting the investigator. The 
investigator should instruct the patient to notify the study site about any new medications, 
he/she takes during the course of the study. 
Guidelines for the use of specific medications are provided below: 
 
Oral corticosteroids 
Oral treatment with systemic corticosteroids will be allowed if the dose was stable for at least 
4 weeks before randomization and maintained stable throughout the study participation. A 
maximum daily dosage of 7.5 mg prednisone (or equivalent) will be allowed. Any change in 
the dose of oral corticosteroids during the study should be recorded on the corresponding eCRF 
page. 
 
Non-steroidal anti-inflammatory drugs (NSAIDs), COX-2 inhibitors, 
acetaminophen/paracetamol, low strength opioids 
Patients on regular use of NSAIDs, COX-2 inhibitors, paracetamol/acetaminophen or low 
strength opioids for the treatment of RA symptoms should be on stable dose for at least 4 weeks

before randomization to allow inclusion and during the treatment period of 48 weeks. Patients 
taking NSAIDs, COX-2 inhibitors, paracetamol/acetaminophen or low strength opioids on a 
PRN basis (as required, no fixed dose schedule) within the 4 weeks before randomization can 
continue to do so in the study. However, they should stop any intake during at least the 24 hours 
before a study visit. 
Any change of the NSAID, COX-2 inhibitor, paracetamol/acetaminophen or low strength 
opioids treatment during the trial should be recorded on the corresponding Concomitant 
medication eCRF page. 
Note: All precautions related to the allowed concomitant medications should be adhered to in 
line with the respective label. 
 
5.5.8 
Prohibited medications 
Use of the following treatments is NOT allowed until study completion: 
• Any biologic or conventional synthetic DMARDs and/or immunosuppressant’s other than 
MTX and adalimumab 
• Any intra-articular injection (i.e. corticosteroid, hyaluron) within 4 weeks prior to baseline 
and during the study 
• Any intramuscular corticosteroid injection within 4 weeks prior to baseline and during the 
study 
• Administration of live vaccines within 3 months prior to baseline and during the study 
Treatment of RA with other TNF-antagonists and/or anti-CD20 agents is not allowed before or 
during the study. If the use of other prohibited medication specified in Table 5-2 is required, 
then the patient should NOT be randomized into the study. If these treatments are stopped 
because their use is no longer required before the patient is being considered for screening in 
this study, wash out periods for these treatments should be applied as indicated in Table 5-2.

No other medications for treatment of RA are allowed to be used routinely during the study. 
Treatments displayed in Table 5-2 could confound the efficacy and may affect safety, and are 
NOT allowed after randomization (baseline; Visit 2) for any indication. If the use of these 
treatments is required, then the patient should NOT be randomized into the study. 
If the medication listed in Table 5-2 was used during the study, it must be discontinued if the 
subject wishes to continue in the study. If the medication is not discontinued, subject will be 
withdrawn. If the patient received a live vaccination during the study, the patient must 
discontinue study treatment. 
The investigator should instruct the patient to notify the study site about any new treatments 
that he/she takes after the start of study. All treatments and significant non-drug therapies 
administered after the patient entered the study must be listed on the Concomitant medications 
eCRF or the Procedures and Significant non-drug therapies eCRF. 
 
5.5.9 
Study drug discontinuation and premature patient withdrawal 
Study drug discontinuation 
Patients may voluntarily discontinue study treatment for any reason at any time. The 
investigator should discontinue study treatment for a given patient if, based on benefit/risk 
assessment, he/she believes that continuation would not be favorable to the patient’s well-being 
or if a patient did not improve (did not achieve the treatment target) or the disease activity 
deteriorated compared to previous DAS28-CRP score. 
Study treatment must be discontinued under the following circumstances: 
• Withdrawal of informed consent

• Violation of methods of contraception as described in Section 6.5.7 
• Emergence of the following AEs: 
• Any severe or serious AE that is not compatible with the administration of study drug 
• In case of a serious infection or sepsis 
• Severe heart failure (NYHA class III or IV), or other severe, uncontrolled 
cardiovascular disease 
• Uncontrolled hypersensitivity to study medication 
• Any persisting laboratory abnormalities that in the judgement of the investigator, 
taking into consideration the patient’s overall status, prevents the patient from 
continuing participation in the study 
• Hepatitis B virus (HBV) infection. Should a patient develop HBV infection during 
the study, the study medication should be discontinued and should not be re-started, 
even after the infection is controlled or resolved. MTX should also be discontinued 
until the HBV infection is controlled or resolved. 
• Occurrence of any signs or symptoms of tuberculosis or suspicion of tuberculosis (per 
the investigator’s discretion) during study course will lead to discontinuation of study 
drug and the patient will be withdrawn from the study 
• Malignancy, except for basal cell carcinoma 
• Pregnancy 
• Use of the prohibited medications as described in Section 5.5.8 
• Any other protocol deviation that results in a significant risk to the patient’s safety 
• Non-responders at Week 24 
• Emergency unblinding 
The date and primary reason for stopping study treatment should be recorded in the eCRF (e.g. 
Study Drug Discontinuation Form). 
See Section 6 for the required assessments of these patients after study drug discontinuation. 
The investigator must also notify the IRT system of the study drug discontinuation. 
Premature patient withdrawal 
Patients may voluntarily withdraw from the study for any reason at any time. They may be 
considered withdrawn if they: 
• State an intention to withdraw 
• Fail to return for visits and after several attempts by the site personnel to reach this 
patients 
• Become lost to follow up for any other reason 
If such withdrawal occurs for any reason the investigator must determine the primary reason 
for a patient’s premature withdrawal and record this information on the Study completion eCRF 
page. The investigator must also notify the IRT system of the premature withdrawal.

Patients who prematurely withdraw from the study, should be scheduled for a final assessment 
visit (as defined for EoS/ Visit 16), as described in Table 6-1. For patients whose status is 
unclear because they fail to appear for study visits without stating an intention to withdraw, the 
investigator should show "due diligence" by contacting the patient, family or family physician 
as agreed in the informed consent and by documenting in the source documents steps taken to 
contact the patient, e.g. dates of telephone calls, registered letters, other. 
If the investigator decides that a patient is not responding adequately to the study medication, 
patient should be withdrawn and may receive thereafter any anti-rheumatic treatments at the 
discretion of the investigator. Patient should undergo a final assessment visit which should be 
performed prior to treatment with the new anti-rheumatic therapy, and will then be withdrawn 
from the study. Lack of study drug efficacy should be stated on the study completion eCRF 
page for these patients. 
Patients who are prematurely withdrawn from the study will not be replaced by newly enrolled 
patients. 
 
5.5.10 
Emergency unblinding of treatment assignment 
Emergency treatment code breaks should only be undertaken when it is essential to treat the 
patient safely and efficaciously. Most often, discontinuation and knowledge of the possible 
treatment assignments are sufficient to treat a study patient who presents with an emergency 
condition. Emergency treatment code breaks are performed using the IRT. When the 
investigator contacts the system to break a treatment code for a patient, he/she must provide the 
requested patient identifying information and confirm the necessity to break the treatment code 
for the patient. The investigator will then receive details of the investigational drug treatment 
for the specified patient and a fax or email confirming this information. The system will 
automatically inform the monitor for the site and the Study lead 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 must provide oral 
and written information to the patient how to contact his/her backup in cases of emergency 
when he/she is unavailable to ensure that unblinding can be performed at any time. The 
investigator will provide protocol number, study treatment name if available, patient number, 
and instructions for contacting the local Sponsor representative (or any entity to which it has 
delegated responsibility for emergency code breaks) to the patient in case an emergency 
treatment code break is required at a time when the investigator and backup are unavailable. 
Study treatment must be discontinued after emergency unblinding by the site. Study drug must 
also be discontinued for any subject whose treatment code has been broken inadvertely or for 
any non-emergency reason by the site. Any unblinding by the site, be it inadvertely or for non- 
emergency reasons, must be reported to the monitor. Patients who are prematurely unblinded 
will be discontinued from study treatment and requested to return 2 weeks after the last study 
drug intake to perform the EoS (Visit 16).

5.5.11 
Study completion and post-study treatment 
A patient will be considered to have completed the study when all scheduled study assessments 
and procedures up to and including Visit 16 (Week 48) have been performed. 
The trial will be completed when the last patient completed the last visit as per protocol. 
Information on when the last administration of study drug took place, the subject’s completion 
or discontinuation from the study and the reason for discontinuation of the study will be 
recorded on the Study Completion eCRF page. Study Completion evaluations must also be 
performed when a subject prematurely withdraws from the study for whatever reason. 
The investigator or site staff must enter study completion (at Week 48) and/or discontinuation 
of a patient as soon as possible in the IRT system. 
It is the investigator’s responsibility to provide follow-up medical care for all patients who are 
prematurely withdrawn from the study. This care may include: initiating another treatment 
outside of the study as deemed appropriate by the investigator. This treatment may be any non- 
biologic DMARD. In case of a biologic treatment, a waiting period of 3-4 weeks before 
initiating the treatment is recommended. 
 
5.5.12 
Early study termination 
The study can be terminated at any time for any reason by the sponsor. Should this be necessary, 
the patient should be seen as soon as possible and treated as described in Section 6 for a 
prematurely withdrawn patient. The investigator may be informed of additional procedures to 
be followed in order to assure that adequate consideration is given to the protection of the 
patient’s interests. The investigator will be responsible for informing Institutional Review 
Boards (IRBs) and/or Ethics Committees (ECs) of the early termination of the trial. The Sponsor 
will inform the relevant Competent Authorities accordingly. 
 
6 
Visit schedule and assessments 
Table 6-1 lists all of the assessments and indicates with an “x” the visits when they are 
performed. 
Patients should be seen for all visits on the designated day within the allowed “visit window” 
specified below. All visits should be planned from the baseline visit date (Day 1/Visit 2) as a 
reference point and not to the previous visit. 
A “visit window” will be allowed during the study as follows: 
• Visit 2: latest 4 weeks after the screening visit 
• Visit 3 to Visit 14: ± 2 days 
• Visit 15 to Visit 16: ± 3 days 
Visit window relates to the originally planned visit schedule. The patient should be instructed 
to contact the investigator, if he/she is unable for any reason to attend a study visit as scheduled. 
During the treatment periods, patients may be seen between scheduled protocol visits, e.g. if 
they experience deterioration of RA, or AEs that in the opinion of the investigator need

intervention or laboratory testing. During these unscheduled visits, study treatment will NOT 
be administered and other study procedures as defined per protocol will NOT be performed. 
During study period 2 between visits 14 and 16 additional visits to the site are allowed if the 
patient requires further training to become proficient at self-administration of study treatment. 
Except for treatment self-administration at the site, no other study procedures would be 
performed and no additional data will be collected. 
Patients who discontinue study drug before completing the study, and those who prematurely 
withdraw from the study treatment for any reason, should be scheduled for a visit as soon as 
possible, at which time all of the assessments listed for the Visit 16 will be performed. Patients 
who prematurely stop study medication for any reason may refuse to attend a final visit and 
assessments, in this case the investigator should document the attempt to explain to the patient 
that a final visit and assessments would be advisable for safety reasons. 
If patients refuse to return for these assessments or are unable to do so, every effort should be 
made to contact them, or their family or primary care physician/ family physician as agreed in 
the informed consent and by documenting in the source documents steps taken to contact the 
patient, e.g. dates of telephone calls, registered letters, other. At this contact, the safety (e.g. 
potential occurrence of AEs or SAEs) and the efficacy (overall disease status self-assessed by 
the patient) outcome as well as the primary reason for a patient’s premature withdrawal should 
be determined. Documentation of attempts to contact the patient should be recorded in the 
source documentation. 
Patients who prematurely withdraw consent for the study will stop all study procedures and will 
continue treatment according to local standards of care. No further information about the patient 
will be collected. 
Patients should report any SAE which occurs during the period of 30 days after the patient has 
stopped study participation (defined as time of last dose of study drug taken or last visit 
whichever is later). 
The investigator should ensure regular contact with the patient (as per routine medical practice) 
for at least 30 days after the study drug discontinuation and capturing/reporting all SAEs 
(regardless of causality) which may occur in this period. 
In addition, the investigator should report SAEs that occur at any time after study 
completion/discontinuation in case the investigator suspects a causal relationship to the study 
drug. 
SAEs reporting needs to be performed as described in Section 7.2.2 of this protocol.

Assessment specifications: 
Visit assessments should be performed following the guidelines below: 
1. All visits should be planned from the baseline visit date (Day 1/Visit 2) as a reference point and not to the previous visit. 
2. Patient to complete FACIT and HAQ-DI© prior to any investigator assessments. 
3. Investigator to enter component parts (TJC, SJC and PGA) of DAS28-CRP score into the eCRF. 
4. Perform all remaining visit procedures as per visit schedule, i.e. all laboratory sample collections including ADA (to be drawn prior to study 
treatment administration), physical examination, vital signs, and assessment of ISR (at site of previous injection). 
5. Use DAS28-CRP derived by clinical database at screening to assess inclusion criteria and for contacting IRT at Visit 2 (Day 1, baseline 
(randomization)) 
6. Enter DAS28-CRP component assessments performed at Visit 14 (Week 24) into the eCRF, then the clinical database shall derive the DAS28- 
CRP score. However due to several days needed to obtain the CRP results from central laboratory, the decision to continue patients in the 
study after Week 24 will be made based on Week 24 DAS28-CRP parameters and the CRP value from Week 22 (Visit 13). 
After all measurements are completed unblinded study site personnel should access IRT and dispense study treatment.

6.1 
Information to be collected on screening failures 
Patients who sign the informed consent form and discontinue prior to randomization at Visit 2 
(Day 1) are considered screening failures. 
If a patient discontinues before randomization and entering the double-blind treatment period, 
IRT must be notified within 5 days and the reason for not being randomized entered on the 
Screening Phase Disposition eCRF. The Screening visit date, the Demography eCRF, Informed 
Consent eCRF, Inclusion/Exclusion Criteria eCRF, and patient re-screening eCRF (if 
appropriate) at a minimum must be completed. 
The AE eCRF and a SAE form should be completed for any SAEs that occurred during the 
screening period. The Withdrawal of consent eCRF should be completed if consent was 
withdrawn during the screening period. The Death eCRF should be completed in the case of a 
death during the screening period. 
Patients can be re-screened once. For a patient to be re-screened, the patient must re-consent, a 
new patient number has to be assigned and all screening assessments have to be repeated. 
 
6.2 
Patient demographics/ other baseline characteristics 
All assessments to determine the baseline characteristics at Visit 2 shall be performed prior to 
first study treatment administration. 
 
6.2.1 
Patient demographics 
The following patient demographic and baseline characteristic data are to be collected for all 
patients: year of birth, age at screening, sex, race and child-bearing potential (for females only). 
 
6.2.2 
Baseline characteristics 
 
6.2.2.1 
Rheumatoid arthritis medical history 
The information to be collected and entered in the eCRF includes: 
• Date of first diagnosis of RA (by a physician) 
• Previous treatments of RA (including previous use of biologic therapies) and the reason 
for their discontinuation. 
 
6.2.2.2 
Relevant medical history/current medical conditions 
Relevant medical history and current medical conditions, excluding RA, will be recorded in the 
eCRF. 
Relevant medical history/current medical condition data includes data up to 6 months prior to 
signature of ICF. Whenever possible, diagnoses and not symptoms should be recorded. 
Clinical relevant findings that are present prior to the start of study drug must be included in the 
Relevant Medical History/Current Medical Conditions eCRF. Significant clinically relevant

findings made after the start of study drug which meet the definition of an Adverse Event must 
be recorded in the AE eCRF. 
 
6.2.2.3 
Determination of tuberculosis status 
Determination of TB status is required before administration of study treatment. TB status must 
be determined by medical history, signs, symptoms, imaging and TB testing (QuantiFERON®- 
TB Gold assay). Any significant findings should be recorded in the eCRF, as necessary. 
 
6.2.2.3.1 Imaging 
A chest X-ray (posteroanterior (PA) or PA and lateral according to the local practice), CT scan 
or MRI obtained within 3 months prior to baseline should be used to determine eligibility. If 
patients do not have a chest X-ray (PA or PA and lateral according to the local practice), CT 
scan, or MRI available at screening (Visit 1) a chest X-ray (PA or PA and lateral according to 
the local practice) must be done prior to randomization. This should only be performed after 
the patient fulfils all other inclusion/exclusion criteria, in order to minimize unnecessary 
exposure to X-ray radiation. 
If the chest X-ray (PA or PA and lateral according to the local practice), CT scan, or MRI 
evaluated by a qualified physician shows evidence of ongoing infectious disease or inactive 
(latent) TB, the patient will not be eligible to enter the study. 
If presence of latent TB is established then TB treatment must be initiated and maintained 
according to local country guidelines 
If the X-ray (PA or PA and lateral according to the local practice), CT scan, or MRI shows 
evidence of any malignant process the patient will not be eligible to enter the study. 
 
6.2.2.3.2 QuantiFERON®-TB Gold In-Tube assay 
A QuantiFERON®-TB Gold In-Tube assay (QFT) will be performed to assess the TB status at 
screening (Visit 1) for all patients. This test will only be used to determine the patient’s 
eligibility for the trial. 
This blood-based assay is specific for Mycobacterium tuberculosis and is not influenced by 
previous Bacillus Calmette-Guérin vaccination or exposure to other Mycobacteria species. This 
test, in contrast to the Purified Protein Derivative (PPD) Skin Test, is also insensitive to a 
booster effect since the patient is not exposed to the bacterial antigen. The assay measures the 
production of interferon-gamma and presents it relative to a negative and a positive control 
sample. Further information is available in the referenced article (Manuel and Kumar 2008). 
The QFT test will be supplied and analyzed 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 laboratory manual. 
 
6.2.3 
Other baseline characteristics 
Other baseline characteristic data to be collected on all patients include (see also Table 6-1):

ECG, vital signs, hematology, clinical chemistry, CRP, ESR urinalysis; for women of child- 
bearing potential a serum pregnancy at screening and urine pregnancy test at baseline; HIV test 
and Hepatitis B or C status (serologic or virologic markers for active or latent Hepatitis B and 
Hepatitis C infections), immunogenicity to adalimumab (ADA), trough serum level, DAS28- 
CRP score, FACIT and HAQ-DI©, Tender joint count, Swollen joint count, Physician’s global 
assessment (PhGA) of disease activity (VAS), Patient’s global assessment (PhGA) of disease 
activity (VAS) and Patient’s global assessment of pain (VAS). 
 
6.3 
Treatment exposure and compliance 
All doses of study treatment administration will be recorded on the appropriate Dosage 
Administration Record eCRF page. 
Compliance during Study Period 1 is not applicable since study treatment will be administered 
by the unblinded study personnel. 
Usage of IMP will also be assessed by an unblinded field monitor using medication pack 
numbers, Drug Label Form information, information collected by IRT and provided by the 
unblinded study personnel. Compliance with IMP administration will first be assessed by the 
appropriate site personnel. 
During Study Period 2 patients will record their self-administered doses in a patient diary. 
Compliance during Study Period 2 will be assessed after interviewing the patient and checking 
the entries in the diary. The appropriate site personnel will transfer these entries to the eCRF. 
The patient must bring back the unused syringes to support study drug accountability. 
 
6.4 
Efficacy 
The investigator or qualified designee will perform assessments necessary for DAS28 score and 
ACR rate calculation at defined study visits. Whenever possible, the same evaluator should 
perform these assessment at all visits. Assessments must be conducted prior to the next 
scheduled dosing of study drug. 
 
6.4.1 
Assessment of Disease Activity Score (DAS28) 
The disease activity score (DAS) is a combined index to measure the disease activity in patients 
with RA. In this study DAS28-CRP and DAS28-ESR will be measured. The DAS28-CRP will 
be used for primary and key secondary endpoint analysis, whereas DAS28-ESR will only be 
used for secondary endpoint analysis. The efficacy assessments will be done at screening, 
baseline, Week 2, Week 4, Week 12, Week 24 and Week 48 (Visits 1, 2, 3, 4, 8, 14 and 16). 
In order to calculate the DAS28-CRP or DAS28-ESR, information about the following disease 
variables is needed: 
The number of swollen joints and tender joints should be assessed using 28-joint count (TJC28 
and SJC28), see Figure 6-1. 
The patient’s general health (GH) or global disease activity measured on a Visual Analogue 
Scale (VAS) of 100 mm (both are useable for this purpose) must be obtained (Prevoo et al 1995).

Adalimumab (GP2017) 
Clinical Trial Protocol GP17-302 
Confidential 
Page 53 
version 4.0/01Feb2017 
 
 
 
 
 
 
 
CRP should be measured in mg/L 
and 
ESR should be measured in mm/hour. 
Using this data, the DAS28 can be calculated using the following formula: 
DAS28-CRP = 0.56 * sqrt(TJC28) +  0.28*  sqrt(SJC28)  +  0.36  *  ln(CRP+1)  + 0.014 * 
GH + 0.96 
DAS28-ESR = 0.56 * sqrt(TJC28) + 0.28 * sqrt(SJC28) + 0.70 * ln(ESR) + 0.014 * GH 
Swollen joints, tender joints and patient’s general health assessment will be entered into the 
eCRF and CRP/ESR will be used to determine DAS28-CRP and DAS28-ESR scores. 
In addition CRP values provided by the central laboratory at both screening and Week 22 will 
be entered into the eCRF and be used to calculate DAS28-CRP scores for the purpose of 
assessing eligibility at randomization and Week 24 only (see Table 6-1). 
The DAS28 provides a number on a scale from 0 to 10 indicating the current activity of the RA 
of the patient. Disease activity definition is described in Table 6-2.

The decision to randomize a patient will be made based on DAS28-CRP score at screening. 
Patients achieving at least moderate DAS28-CRP response at Week 24 (calculated using CRP 
value from Week 22 and DAS28 parameters from Week 24) will either continue or be switched 
to GP2017 at Week 24 and will continue in the study until Week 48. Moderate DAS28-CRP 
response at Week 24 is assessed as defined in Table 6-3. 
Patients not achieving at least a moderate DAS28-CRP response at Week 24 will have their 
final study assessments (EoS/ Visit 16) at this time point and will discontinue the study.

Due to several days needed to obtain the CRP results from central laboratory, the decision to 
continue patients in the study after Week 24 will be made based on Week 24 DAS28 parameters 
and the CRP value from Week 22. However for the statistical analysis the DAS28-CRP score 
at Week 24 will be calculated based on the Week 24 CRP value provided by the central 
laboratory.

American College of Rheumatology (ACR) Response Criteria 
This efficacy variable is the clinical response to treatment according to ACR improvement 
criteria (Felson et al 1995), (see Appendix 2). 
A patient will be considered a responder according to ACR20 criteria if she/he fulfills all 
following three criteria: 
• at least 20% improvement from baseline in tender joint count, using the 68-joint count 
• at least 20% improvement from baseline in swollen joint count, using the 66-joint count 
• and at least 20% improvement from baseline in at least 3 of the following 5 measures: 
a. Patient’s assessment of RA pain (VAS 100 mm) 
b. Patient’s global assessment of disease activity (VAS 100 mm)

c. Physician’s global assessment of disease activity (VAS 100 mm) 
d. Patient self-assessed disability (Health Assessment Questionnaire [HAQ] Disability 
Index) 
e. CRP or ESR 
ACR50 and ACR70 are defined as ACR20 replacing ‘20% improvement’ by ‘50% 
improvement’ and ‘70% improvement’ respectively. 
The ACR criteria will be calculated for screening, baseline, Week 4, Week 12, Week 24 and 
Week 48 (Visits 1, 2, 4, 8, 14 and 16). 
 
6.4.4 
Patient assessment of RA pain 
The patient’s assessment of pain will be performed at screening, baseline, Week 2, Week 4, 
Week 12, Week 24 and Week 48 (Visits 1, 2, 3, 4, 8, 14 and 16) using 100 mm visual analog 
scale (VAS) ranging from ‘no pain’ to ‘unbearable pain’ after the question “please indicate with 
a vertical mark (|) through the horizontal line the most pain you had from your rheumatoid 
arthritis over the last 24 hours”. At the investigator’s site the distance in mm from the left edge 
of the scale will be measured and the value will be entered on the eCRF. 
 
6.4.5 
Patient global assessment of disease (PtGA) 
The patient’s global assessment of disease activity will be performed at screening, baseline, 
Week 2, Week 4, Week 12, Week 24 and Week 48 (Visits 1, 2, 3, 4, 8, 14 and 16) using 100 
mm VAS ranging from “very good” to “very poor”, after the question "Considering all the ways 
rheumatoid arthritis affects you, please indicate with a vertical mark ( | ) through the horizontal 
line how well you are doing”. At the investigator’s site the distance in mm from the left edge of 
the scale will be measured and the value will be entered on the eCRF. To enhance objectivity, 
the treating physician performing the PhGA must not be aware of the specific patient’s global 
assessment of disease activity. 
 
6.4.6 
Physician global assessment of disease activity (PhGA) 
The physician’s global assessment of disease activity will be performed at screening, baseline, 
Week 2, Week 4, Week 12, Week 24 and Week 48 (Visits 1, 2, 3, 4, 8, 14 and 16) using 100 
mm VAS ranging from “very good” to “very poor”, after the question “Considering all the ways 
rheumatoid arthritis affects your patient, how would you rate his or her condition today?” 
To enhance objectivity, the physician must not be aware of the specific patient’s global 
assessment of disease activity, when performing his/her own assessment on that patient. The 
investigator will make this evaluation on a paper VAS, then measure the distance in mm from 
the left edge of the scale to the vertical mark, and report the value on the eCRF. 
 
6.4.7 
Health-related Quality of Life Disability Index 
The patient health assessment questionnaire disability index (HAQ-DI©), will be used to assess 
physical ability and functional status of patients as well as quality of life (Fries et al 1980; Bruce 
and Fries 2003). HAQ-DI© will be available to centers in validated versions of all local 
languages. Patients will not be eligible for the study if they are not fluent with the HAQ-DI© 

Hexal AG, Sandoz Inc.

languages available at the site. Patients will complete the questionnaire at baseline, Week 4, 
Week 12, Week 24 and Week 48 (Visits 2, 4, 8, 14 and 16). 
 
Scoring of the HAQ© 
The HAQ© will be scored in accordance with the recommendation from the developers outlined 
in the “HAQ PACK” from Stanford University, California. 
The following coding is to be used for the 8 categories of the disability outcome dimension. 
Without ANY difficulty = 0; with SOME difficulty = 1; with MUCH difficulty = 2; UNABLE 
to do = 3. 
Within each of the 8 categories only the item indicating the most severe impairment contributes 
to the category score. If the subject requires the use of aids, devices or help from another to 
accomplish any of the activities in an associated category, then the score for that category will 
be assigned the value 2, unless the score is already 3 (i.e. scores of 0 or 1 are increased to 2). 
Associated categories are defined in the “HAQ PACK”. From the scores for each category a 
Standard Disability Index (SDI) is computed by summing the computed scores for each 
category and dividing by the number of categories answered. The SDI is not computed if the 
subject does not have scores for at least 6 categories. This SDI is the HAQ© score, which will 
be used in the statistical analyses of this instrument. The range for this score is (0, 3). 
 
HAQ© Data Collection 
The HAQ© is to be completed by the subjects in their local languages. The questionnaires should 
be completed by the subjects in a quiet area free from disturbance, and before any visit 
assessments. Subjects should receive no help from family members; if questions cannot be 
answered alone (due to problems with reading or understanding), then the doctor or nurse 
should read the questions and record the subject’s responses without influencing their answers. 
The information provided is strictly confidential and will be treated as such. 
 
6.4.8 
Functional Assessment of Chronic Illness Therapy - Fatigue Scale 
(FACIT- Fatigue©) 
The Functional Assessment of Chronic Illness Therapy – Fatigue Scale (FACIT-Fatigue©) is a 
13- item questionnaire (Cella et al 1993; Yellen et al 1997) that assesses self-reported fatigue 
and its impact upon daily activities and function. The purpose of FACIT-Fatigue© in this study 
is to assess the impact of fatigue on patients. The score is calculated as described in the appendix 
section (Appendix 3). This instrument/questionnaire will be completed by the patient at baseline, 
Week 4, Week 12, Week 24 and Week 48 (Visits 2, 4, 8, 14 and 16).

ESR 
Blood for this assessment will be obtained at screening, baseline, Week 2, Week 4, Week 12, 
Week 24, Week 36 and Week 48 (Visits 1, 2, 3, 4, 8, 14, 15 and 16) in order to identify the 
presence of inflammation, to determine its severity, and to monitor response to treatment. ESR 
will be analyzed locally and ESR results will be entered in the eCRF.

Safety 
6.5.1 
Physical examination 
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, 
and extremities, vascular and neurological. If indicated based on medical history and/or 
symptoms, rectal, external genitalia, breast, and pelvic exams will be performed in addition to 
the above at screening, baseline, Week 24 and Week 48 (Visits 1, 2, 14 and 16). 
A short physical exam will include the examination of general appearance. A short physical 
exam will be done at all visits starting from Visit 3 except where a complete physical 
examination is required (see above). 
Information for all physical examinations must be included in the source documentation at the 
study site. Clinical relevant findings that are present prior to the start of study drug must be 
included in the Relevant Medical History/Current Medical Conditions eCRF. Clinically 
relevant findings made after the start of study drug which meet the definition of an Adverse 
Event must be recorded on the Adverse Event eCRF. 
 
6.5.2 
Vital signs 
Vital signs include blood pressure (BP) and pulse measurements and will be done at each study 
visit starting from Visit 1. After the patient has been sitting for five minutes, with back 
supported and both feet placed on the floor, systolic and diastolic blood pressure will be 
measured three times using an automated validated device, e.g. OMRON, with an appropriately 
sized cuff. The repeat sitting measurements will be made at 1 - 2 minute intervals and the mean 
of the three measurements will be used. In case the cuff sizes available are not large enough for 
the patient's arm circumference, a sphygmomanometer with an appropriately sized cuff may be 
used.

QuantiFERON®-TB Gold In-Tube assay 
A QuantiFERON®-TB Gold In-Tube assay (QFT) will be performed to assess the TB status at 
screening (Visit 1) for all patients. This test will only be used to determine the patient’s 
eligibility for the trial. Further information is available in Section 6.2.2.3.2 and in the referenced 
article (Manuel and Kumar 2008). 
 
6.5.4.8 
Special Proteins 
Special proteins will be measured to evaluate the baseline immunological status of RA as well 
as the changes during treatment with adalimumab. 
 
6.5.4.8.1 Rheumatoid factor 
Rheumatoid factor assessment as a measure of changes in RA serological status will be 
performed at screening, Week 12, Week 24 and Week 48 (Visits 1, 8, 14 and 16). All parameters 
will be analyzed centrally. 
 
6.5.4.8.2 Anti-CCP Antibodies 
Anti-citrullinated protein (Anti-CCP) antibody assessment will be performed as a measure of 
changes in RA serological status at screening, Week 12, Week 24 and Week 48 (Visits 1, 8, 14 
and 16). Anti-CCP Antibodies will be analyzed centrally. 
 
6.5.4.9

Week 12, Week 24, Week 36 and Week 48 (Visits 1, 2, 4, 8, 14, 15, and 16). 
 
6.5.5 
Electrocardiogram (ECG) 
A standard 12 lead ECG will be performed at screening, Week 24 and Week 48 (Visits 1, 14 
and 16/ EoS). Interpretation of the tracing is documented on the ECG eCRF. Each ECG tracing 
should be labeled with the study number, patient initials, patient number, date, and kept in the 
source documents at the study site. Clinically significant abnormalities detected at screening 
(Visit 1) should also be recorded on the relevant Medical history/Current medical conditions 
eCRF page. Clinically significant abnormalities newly detected during the study should be 
recorded on the AE eCRF page. Clinically significant findings must be discussed with the 
Medical Monitor prior to enrolling the patient in the study. 
 
6.5.6 
Immunogenicity and adalimumab trough levels 
As with all therapeutic proteins, there is a potential for immunogenicity and the emergence of 
antibodies to human recombinant proteins is well documented. Antibodies directed against a 
therapeutic agent may have neutralizing activity and interfere with the efficacy of the treatment. 
For safety reasons, screening for anti-adalimumab antibodies (ADA) has been included in this 
study.

Immunogenicity will be assessed by measuring anti-adalimumab antibody levels in serum of 
all subjects. During the study, immunogenicity will be assessed at: 
• baseline, Week 2, Week 4, Week 12, Week 24, Week 36 and Week 48 (at Visits 2, 3, 4, 8, 
14, 15, and 16) 
For details on blood collection time points and sample information please refer to Table 6-4. 
To support the evaluation of immunogenicity, adalimumab trough levels will be determined at 
every time-point when blood samples for ADA assessment are taken. Thereby, the drug 
tolerance level of the ADA method (which will be determined during method validation) can 
be compared with the determined drug levels. For details on blood collection time points and 
sample information please refer to Table 6-5. 
 
6.5.6.1 
Collection and handling of blood samples for immunogenicity and 
serum drug trough levels 
Blood samples will be obtained pre-dose at baseline, Week 2, Week 4, Week 12, Week 24, 
Week 36 and Week 48 (at Visits 2, 3, 4, 8, 14, 15, and 16) for detection of antibody formation 
against adalimumab and analysis of serum drug trough levels. All samples will be taken by 
direct venipuncture into serum separator tubes. 
 
Serum collection for ADA assessment 
Four aliquots of serum samples per scheduled time-point for ADA assessment will be generated. 
The detailed sample handling and serum preparation will be described in the laboratory manual. 
Aliquot one and two and aliquot three on request will be used for bioanalysis. The fourth aliquot 
will be used as back-up sample. Dates and times of blood collection will be recorded in the 
Immunogenicity Blood Collection eCRF page. For details on immunogenicity blood sample 
collection, labeling, handling and shipment, please refer to the Laboratory Manual.

Storage and archiving of serum drug concentration and ADA samples 
 
All serum drug concentration samples and ADA samples will be stored at ≤ -70°C. For serum 
drug concentration samples, the following archiving applies: 
• Aliquot 1: will be discarded 6 months after availability of the final clinical study report. 
• Aliquot 2: storage at the central lab should not exceed the duration of 6 months after 
availability of the final clinical study report; after this time the Sponsor has to decide if 
these aliquots will be discarded. 
• Aliquot 3: will be stored by the Sponsor at approximately ≤-70°C until marketing 
authorization in a regulated market (e.g. EU, US), but maximally up to 15 years. 
For serum ADA samples, the following archiving applies: 
• Aliquot 1 and 2: will be discarded 6 months after availability of the final clinical study 
report. 
• Aliquot 3: storage at the central lab should not exceed the duration of 6 months after 
availability of the final clinical study report; After this time the Sponsor has to decide if 
these aliquots will be discarded. 
• Aliquot 4: will be stored by the Sponsor at approximately ≤-70°C until marketing 
authorization in a regulated market (e.g. EU, US), but maximally up to 15 years. 
Alternatively, samples which are left over after assessment of serum drug concentration or ADA 
assessment can be used for future research as described in section 6.8.1 after the specified 
archiving/storage period. All optional future research will be done at the sponsor’s discretion if 
patients consent to do so by signing a separate optional informed consent form. Samples will 
be stored maximally up to 15 years.

Labels used in this study will not contain information, which would allow identifying the 
treatment given. This assures that the analysts will analyze the samples in a blinded manner. 
All samples will be given a unique barcode number. 
 
6.5.6.2 
Analytical methods for ADA 
Immunogenicity of adalimumab as determined by the formation of antibodies against the drug 
will be evaluated by using validated immunoassays. The validation procedure and serum sample 
analysis will follow international guidelines. 
All samples will first be analyzed in a binding ADA screening assay. Study samples with a 
result below the validated screening cut-point are negative for anti-adalimumab antibodies and 
will be reported accordingly. In the event of a positive result (result above the screening cut- 
point) the sample will be additionally analyzed in a secondary confirmatory assay (specificity 
assay). In case the assay signal can be reduced after addition of excess of adalimumab beyond 
the validated confirmatory cut-point, a sample will be reported as confirmed positive for binding 
anti-adalimumab antibodies. In contrast, samples with a result above the screening cut-point in 
the screening assay but which are negative in the confirmatory assay will be reported as negative. 
The titer of all confirmed positive results will be reported in the CSR. In addition, all confirmed 
positive ADA samples will be further analyzed for their neutralization potential in a neutralizing 
antibody (NAb) assay. NAb results will also be reported in the CSR.

Serum concentration of 
 adalimumab will be measured

6.5.6.4 
Additional research/analyses 
The subject’s remaining adalimumab trough concentrations and ADA samples (aliquot 3 and 
aliquot 4 respectively) will be stored until approval of the drug in a highly regulated market (e.g. 
EU, US), but maximally up to 15 years and may be used for additional research and/or analysis 
 
 
 
 
In addition, development activities such as method evaluation and validation related to 
adalimumab might be done. All optional additional analyses will be done at the sponsor’s 
discretion if subjects consent to do so. A decision to perform such research analysis would be 
based on outcome data of this trial or from new scientific findings related to the drug class, as 
well as reagent and assay availability.

6.5.7 
Pregnancy and assessments of fertility 
Neither GP2017 nor Humira® should be given to pregnant women; therefore a highly effective 
method of birth control must be used for women of child-bearing potential (see Section 4.2). 
Women of child-bearing potential (WOCBP) are all women physiologically capable of 
becoming pregnant, including women whose career, lifestyle, or sexual orientation precludes 
intercourse with a male partner and women whose partner have been sterilized by vasectomy 
or other means. 
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 she is considered not of child-bearing potential. 
All women of child-bearing potential (WOCBP) according to the definition above should have 
a serum pregnancy test at Visit 1 (Screening). In addition, all women of child-bearing potential 
(WOCBP) will have a urine pregnancy test at Visits 2, 4, 6, 8, 10, 12, 14, 15, 16. A positive 
urine pregnancy test requires immediate discontinuation of study drug and should be confirmed 
with a serum pregnancy test. 
WOCBP, defined as all women physiologically capable of becoming pregnant, must use highly 
effective contraception during the study and for 70 days after stopping treatment. Highly 
effective contraception i.e. one that results in an annual pregnancy rate < 1%, is defined as 
either: 
• Total abstinence (when this is in line with the preferred and usual lifestyle of the subject). 
Note: Periodic abstinence [e.g. calendar, ovulation, symptothermal, post-ovulation 
methods] and withdrawal are not acceptable methods of contraception and will lead study 
drug discontinuation and patient withdrawal. 
• Sterilization: have had surgical bilateral oophorectomy (with or without hysterectomy) or 
tubal ligation at least 6 weeks before taking study treatment. In case of oophorectomy 
alone, this is only acceptable when the reproductive status of the woman has been 
confirmed by follow up hormone level assessment. Male partner sterilization (with the 
appropriate post-vasectomy documentation of the absence of sperm in the ejaculate). (For 
female study subjects, the vasectomized male partner should be the sole partner for that 
patient). 
• Use of a combination of any two of the following (a+b or a+c or b+c): 
a. Use of oral, injected or implanted hormonal methods of contraception or other forms 
of hormonal contraception that have comparable efficacy (failure rate <1%), for 
example hormone vaginal ring or transdermal hormone contraception; 
b. Placement of an intrauterine device (IUD) or intrauterine system (IUS); 
c. Barrier methods of contraception: condom or occlusive cap (diaphragm or 
Cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository.

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. 
Sexually active men should continue to practice the barrier method of contraception as already 
initiated at the start of their MTX treatment.

Appropriateness of safety measurements 
The safety assessments selected are standard for this indication/patient population.

Pharmacokinetics 
No formal PK will be performed. Trough levels of adalimumab will be measured in support of 
immunogenicity assessment. Blood samples for determination of trough level of adalimumab 
will be collected at the same time points as samples for ADA assessment. (see Section 6.5.6).

7.1 
Adverse events 
An adverse event is the appearance or worsening of any undesirable sign, symptom, or medical 
condition occurring after starting the study drug even if the event is not considered to be related 
to study drug. Study drug includes the investigational drug under evaluation and the comparator 

Hexal AG, Sandoz Inc.

drug that is given during any phase of the study. Medical conditions/diseases present before 
starting study drug are only considered adverse events if they worsen after starting study drug. 
The occurrence of adverse events should be sought by non-directive questioning of the patient 
at each visit during the study. Adverse events also may be detected when they are volunteered 
by the patient during or between visits or through physical examination, laboratory test, or other 
assessments. 
Abnormal laboratory values or test results constitute adverse events only if they fulfill at least 
one of the following criteria: 
• they induce clinical signs or symptoms 
• they are considered clinically significant 
• they require therapy 
Clinically significant abnormal laboratory values or test results should be identified through a 
review of values outside of normal ranges/clinically notable ranges, significant changes from 
baseline or the previous visit, or values which are considered to be non-typical in patient with 
underlying disease. Investigators have the responsibility for managing the safety of individual 
patient and identifying adverse events. 
Adverse events must be recorded on the Adverse Events (e)CRF with the following 
information: 
1. the severity grade if Common Toxicity Criteria AE (CTCAE) grading does not exist for an 
adverse event, use 
• mild: usually transient in nature and generally not interfering with normal activities 
• moderate: sufficiently discomforting to interfere with normal activities 
• severe: prevents normal activities 
If CTCAE grading exists for an adverse event, use: 
1=mild 
2=moderate 
3=severe 
4=life-threatening 
CTCAE Grade 5 (death) is not used, but is collected in other CRFs (Study Completion, 
Death/Survival). 
2. its relationship to the study drug(s) (suspected/not suspected) 
• Not suspected: The temporal relationship of the clinical event to trial drug 
administration makes a causal relationship unlikely, or other drugs, therapeutic 
interventions or underlying conditions provide a sufficient explanation for the 
observed event.

Clinical Trial Protocol GP17-302

Page 68 
version 4.0/01Feb2017 
 
 
 
 
 
 
 
• Suspected: The temporal relationship of the clinical event to trial drug administration 
makes a causal relationship possible, and other drugs, therapeutic interventions or 
underlying conditions do not provide a sufficient explanation for the observed event. 
• If the event is due to lack of efficacy or progression of underlying illness (i.e. 
progression of the study indication) the assessment of causality will usually be ‘Not 
suspected’. The rationale for this guidance is as follows: 
• the symptoms of a lack of efficacy or progression of underlying illness are not 
caused by the trial drug, they happen in spite of its administration 
• both lack of efficacy and progression of underlying disease can only be evaluated 
meaningfully by an analysis of cohorts, not on a single patient 
3. its duration (start and end dates or if continuing at final exam) 
4. whether it constitutes a serious adverse event (SAE) (see Section 7.2.1 for definition of SAE) 
Unlike routine safety assessments, SAEs are monitored continuously and have special 
reporting requirements; see Section 7.2. 
5. action taken 
All adverse events should be treated appropriately. Treatment may include one or more of the 
following: no action taken (i.e. further observation only); study drug dosage 
adjusted/temporarily interrupted; study drug permanently discontinued due to this adverse 
event; concomitant medication given; non-drug therapy given, patient hospitalized/patient’s 
hospitalization prolonged . The action taken to treat the adverse event should be recorded on the 
Adverse Event CRF. 
6. It’s outcome (not recovered/not resolved; recovered/resolved; recovering/resolving, 
recovered/resolved with sequelae; fatal; or unknown) 
Once an adverse event is detected, it should be followed until its resolution or until it is judged 
to be permanent, and assessment should be made at each visit (or more frequently, if necessary) 
of any changes in severity, the suspected relationship to the study drug, the interventions 
required to treat it, and the outcome. 
Information about common side effects already known about the investigational drug can be 
found in the IB or will be communicated between IB updates in the form of Investigator 
Notifications. This information will be included in the patient informed consent and should be 
discussed with the patient during the study as needed. 
The investigator should also instruct each patient to report any new adverse event (beyond the 
protocol observation period) that the patient, or the patient’s personal physician, believes might 
reasonably be related to study treatment. This information should be recorded in the 
investigator’s source documents, however, if the AE meets the criteria of an SAE, it must be 
reported to the sponsor.

7.2 
Serious adverse events 
7.2.1 
Definition of SAE 
An SAE is defined as any adverse event (appearance of or worsening of any pre-existing 
undesirable sign(s), symptom(s) or medical conditions(s)), which meets any one of the 
following criteria: 
• is fatal or life-threatening 
• results in persistent or significant disability/incapacity 
• constitutes a congenital anomaly/birth defect 
• requires inpatient hospitalization or prolongation of existing hospitalization, unless 
hospitalization is for: 
• routine treatment or monitoring of the studied indication, not associated with any 
deterioration in condition (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 the start of study drug 
• treatment on an emergency outpatient basis for an event not fulfilling any of the 
definitions of a SAE given above and not resulting in hospital admission 
• social reasons and respite care in the absence of any deterioration in the patient’s 
general condition 
• is medically significant, i.e. defined as an event that jeopardizes the patient or may require 
medical or surgical intervention to prevent one of the outcomes listed above 
Life-threatening in the context of a SAE refers to a reaction in which the patient was at risk of 
death at the time of the reaction; it does not refer to a reaction that hypothetically might have 
caused death if more severe (see Annex IV, ICH-E2D Guideline). 
All malignant neoplasms will be assessed as serious under “medically significant” if other 
seriousness criteria are not met. 
Any suspected transmission via a medicinal product of an infectious agent is also considered a 
serious adverse reaction. 
Medical and scientific judgment should be exercised in deciding whether other situations should 
be considered serious reactions, such as important medical events that might not be immediately 
life threatening or result in death or hospitalization but might jeopardize the patient or might 
require intervention to prevent one of the other outcomes listed above. Examples of such events 
are intensive treatment in an emergency room or at home for allergic bronchospasm, blood 
dyscrasias or convulsions that do not result in hospitalization. 
 
7.2.2 
SAE reporting 
To ensure patient safety, every SAE, regardless of suspected causality, occurring after the 
patient has provided informed consent and until 30 days after the patient has stopped study 
participation (defined as time of last dose of study drug taken or last visit whichever is later) 

Hexal AG, Sandoz Inc.

must be reported to the sponsor [or designated CRO] within 24 hours of learning of its 
occurrence. 
Any SAEs experienced after this 30 day period should only be reported to the sponsor [or 
designated CRO] if the investigator suspects a causal relationship to the study drug. 
Recurrent episodes, complications, or progression of the initial SAE must be reported as follow- 
up to the original episode, regardless of when the event occurs. This report must be submitted 
within 24 hours of the investigator receiving the follow-up information. An SAE that is 
considered completely unrelated to a previously reported one should be reported separately as 
a new event. 
Information about all SAEs is collected and recorded on the Serious Adverse Event Report 
Form. The investigator must assess the relationship to study drug, complete the SAE Report 
Form in English, and send the completed, signed form within 24 hours to the sponsor or 
delegated CRO. The contact information for SAE/pregnancy reporting is 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 at the 
study site. 
Follow-up information is sent to the same person to whom the original SAE Report Form was 
sent, using a new SAE Report Form stating that this is a follow-up to the previously reported 
SAE. The follow-up information should describe whether the event has resolved or continues, 
if and how it was treated, whether the blind was broken or not, and whether the patient continued 
or withdrew from study participation. 
If the SAE is not previously documented in the IB or Package Insert (new occurrence) and is 
thought to be related to the study drug, the sponsor may urgently require further information 
from the investigator for Health Authority reporting. The sponsor may need to issue an 
Investigator Notification (IN) to inform all investigators involved in any study with the same 
drug 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 Directive 2001/20/EC or as per national regulatory requirements 
in participating countries. 
 
7.3 
Pregnancy reporting 
To ensure patient safety, each pregnancy in a patient on study drug must be reported to the 
sponsor within 24 hours of learning of its occurrence. The pregnancy should be followed up to 
determine outcome, including spontaneous or voluntary termination, details of the birth, and 
the presence or absence of any birth defects, congenital abnormalities, or maternal and/or 
newborn complications. 
Pregnancy should be recorded on a Clinical Trial Pregnancy Form and reported by the

Data review and database management 
8.1 
Site monitoring 
Before study initiation at a site, the protocol and (e)CRFs will be reviewed with the investigators 
and their staff by a sponsor representative or representative of the delegated CRO at an 
investigator meeting or a site initiation visit. During the study, the blinded monitor will visit the 
site regularly to check the completeness of patient records, the accuracy of entries on the 
(e)CRFs, the adherence to the protocol and to Good Clinical Practice and the progress of 
enrollment. In order to maintain blinding of the study, an unblinded monitor will be assigned to 
ensure that study drug is being received, stored, dispensed and accounted for according to 
specifications. Key study personnel must be available to assist the monitors during monitoring 
visits. 
The investigator must maintain source documents for each patient in the study, consisting of 
case and visit notes (hospital or clinic medical records) containing demographic and medical 
information, laboratory data, electrocardiograms, and the results of any other tests or 
assessments. All information on (e)CRFs must be traceable to these source documents in the 
patient's file. The investigator must also keep the original informed consent form signed by the 
patient (a signed copy is given to the patient). 
The investigator must give the monitor access to all relevant source documents for monitoring 
to confirm their consistency with the (e)CRF entries. The sponsor’s 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 (e)CRFs are performed according to the study-specific monitoring plan. No 
information available in source documents about the identity of the patients will be disclosed. 
 
8.2 
Data collection and quality control 
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 Electronic Data Capture system 
until they have been trained. Automatic validation programs check for data discrepancies by 
generating appropriate error messages and allow the data to be confirmed or corrected before 
transfer of the data to the CRO working on behalf of the sponsor. Monitors will review the 
CRFs for completeness and accuracy and instruct site personnel to make any required 
corrections or additions. Subsequently, the entered data are systematically checked by Data 
Management staff, using error messages printed from validation programs and database listings. 
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 the CRO who will make the 
correction to the database. The signed copy of the Data Query Form is kept at the investigator 
site.

The Investigator must certify with his electronic signature that the data entered into the 
Electronic Case Report Forms are complete and accurate. After database lock, the investigator 
will receive a password protected CD-ROM or paper copies of the patient data for archiving at 
the investigational site. 
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. 
Results of laboratory samples that will be processed centrally will be sent electronically to the 
designated CRO while result of the ESR performed locally would be entered into the Electronic 
Case Report Form by the site staff. Randomization codes and data about all study drugs 
dispensed to the patient and all dosage changes will be tracked using an Interactive Response 
Technology System (IRT). The system will be supplied by a vendor(s), who will also manage 
the database. The database will be sent electronically to the sponsor (or a designated CRO). 
At the conclusion of the study, the occurrence of any emergency code breaks will be determined 
after reviewing of all code break reports and unused drug supplies to the sponsor or delegated 
CRO. The occurrence 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. 
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 the 
sponsor. 
 
8.3 
Data Monitoring Committee 
A DMC will review the safety data of the study on a regular basis in order: 
• to independently assess the causality of suspected SAEs 
• to ensure periodic monitoring and periodic review of patient data on suspected SAEs 
• to make recommendations based on risk assessments 
A charter will be established between sponsor and the DMC to outline the DMC’s 
responsibilities and procedures.

The data including Study Period 2 will be evaluated to assess long-term safety, immunogenicity 
and efficacy of GP2017 up to Week 48 and to investigate the effects of a switch from US- 
licensed Humira® to the proposed biosimilar GP2017 in patients with at least a moderate 
response, with respect to efficacy, safety and immunogenicity. 
All data will be collected fully blinded. All analyses shall be performed after all patients have 
completed or were prematurely withdrawn from the study and the study CSR shall be written. 
Treatment groups for analysis will include: 
• Study period 1: 
GP2017 
US-licensed Humira® 
• Study period 2: 
continuous GP2017 
US-licensed Humira® switched to GP2017 
Summary statistics for continuous variables will include N, mean, standard deviation, minimum, 
median and maximum. Summary statistics for discrete variables will be presented in 
contingency tables and will include absolute and relative frequencies. 
If not otherwise specified, p-values will be presented as two-sided p-values and two-sided 
confidence intervals (CI) will be displayed. 
 
9.1 
Analysis sets 
The following analysis sets will be used in this study: 
Study Period 1 Full analysis set (SP1 FAS): consists of all randomized subjects to whom IMP 
has been assigned. Following the intent-to-treat principle, subjects will be analyzed according 
to the treatment assigned at randomization. Subjects will be analyzed as per the actual true strata 
and not necessarily the assigned strata. 
Study Period 2 FAS (SP2 FAS): The SP2 FAS set includes all SP1 FAS patients entering 
Study Period 2. 
Week 12 Per-protocol analysis set (W12 PPS): consists of all subjects in the SP1 FAS who 
complete Week 12/Visit 8 and do not have any major protocol deviations regarding the 
evaluation of the study’s primary objective. 
Study Period 1 PPS (SP1 PPS): consists of all subjects in the SP1 FAS who complete Week 
24/Visit 14 and do not have any major protocol deviations regarding the evaluation of the 
study’s key secondary objective. 
Study Period 2 PPS (SP2 PPS): consists of all subjects in the SP2 FAS who complete the full 
study (Week 48/Visit 16) and do not have any major protocol deviations with regards to any 
efficacy assessment. 
Additional potential exclusions from the PPS analysis sets will be assessed and confirmed 
during the BDRMs.

9.4 
Analysis of the primary objective(s) 
9.4.1 
Variable 
The primary variable is DAS28-CRP change from baseline at Week 12. 
 
9.4.2 
Statistical hypothesis, model, and method of analysis 
The following statistical hypotheses will be used to assess equivalence between GP2017 and 
US-licensed Humira® with regards to DAS28-CRP change from baseline at Week 12: 
H0: |GP2017 – Humira®| ≥ 0.6 
versus 
H1: |GP2017 – Humira®| < 0.6 
To address both EMA and FDA regulatory requirements for establishing therapeutic 
equivalence both 95% and 90% confidence intervals shall be estimated and used to assess 
equivalence of DAS28-CRP change from baseline at Week 12. 
Therapeutic equivalence in terms of DAS28-CRP will be concluded if the 95% (as required by 
EMA) or 90% (as required by FDA) confidence interval for the difference in DAS28-CRP 
change from baseline at Week 12 between the two treatment groups is completely contained 
within the interval [-0.6; 0.6]. This is statistically equivalent to calculating two independent 
one-sided tests at a 2.5%/5% alpha level (one in each direction), of which both have to be 
successful. 
A mixed-model repeated measures (MMRM) analysis will be performed for DAS28-CRP 
change from baseline as the endpoint including treatment, stratification factors, time, the 
interaction between time (visits) and treatment all as categorical variables, and baseline DAS28- 
CRP as a continuous variable. 
DAS28CRPCFB = treat + strata + time + (time ∗ treat) + baseline DAS28CRP 
MMRM is a standard approach to longitudinal analysis of continuous endpoints. Its roots bear 
into linear mixed modeling methodology and it is specified as a multivariate normal model of 
the longitudinal data. More specifically, this model includes a saturated visit-by-treatment 
structure for the mean. That is, time is considered as a factor rather than a continuous variable, 
and thus MMRM makes no assumption about trends over time. Traditional linear mixed models 
make further assumptions about the covariance of within/intra-patient observations, which can 
either originate from random effects or residual errors. With MMRM the covariance structure 
is specified only through the residual error term. The most flexible covariance matrix is 
unstructured, that is, all variance and covariance parameters are estimated. The actual 
covariance matrix to be used shall be determined within the statistical analysis plan prior to 
unblinding. 
Mean change from baseline at Week 12, standard errors and the two-sided 95%/90% CI for the 
mean difference between GP2017 and US-licensed Humira® will be estimated from the model 
and the 95%/90% CI compared to the pre-specified equivalence margin of [-0.6; 0.6]. An effect

size of 0.6 in DAS28-CRP score is considered to be clinically meaningful for comparison of 
GP2017 with US-licensed Humira® in this patient population. 
The primary analysis will be performed on the Week 12 Per-protocol set (W12 PPS) which is 
the most appropriate analysis set to use when testing for equivalence. 
 
9.4.3 
Handling of missing values/censoring/discontinuations 
No imputation will be performed for missing components of the DAS28-CRP score or the 
computed DAS28-CRP score itself. 
 
9.4.4 
Supportive analyses 
The same MMRM analysis as used for analysis of the primary endpoint will be conducted as a 
sensitivity analysis using the SP1 FAS. 
 
 
9.5 
Analysis of secondary objectives 
9.5.1 
Key secondary variable 
The key secondary variable is time-weighted averaged change from baseline in DAS28-CRP 
until Week 24. 
 
9.5.1.1 
Statistical hypothesis, model, and method of analysis 
Time-weighted averaged change from baseline in DAS28-CRP until Week 24 (standardized 
AUEC approach) will be estimated from an ANCOVA 
The averaged change from Week 2 and Week 24 will be estimated by a time-weighted mean 
across visits. The weights are derived using the standard formula from the trapezoidal rule 
across the visits. Mean averaged change from baseline from Week 2 to Week 24, standard 
errors and the two-sided 95%/90% CI for the mean difference between GP2017 & and US- 
licensed Humira® will be estimated from the model and the 95%/90% CI compared to the pre- 
specified equivalence margin of [-0.6; 0.6]. 
To address both EMA and FDA regulatory requirements for establishing therapeutic 
equivalence both 95% and 90% confidence intervals shall be estimated and used to assess 
equivalence of time-weighted averaged change from baseline in DAS28-CRP until Week 24. 
No imputation will be performed for missing components of the DAS28-CRP score or the 
computed AUEC value itself. 
The key secondary analysis will be performed on the Study Period 1 Per-protocol set (SP1 PPS) 
which is the most appropriate analysis set to use when testing for equivalence. 
An idential sensitivity analysis as specified above for the SP1 PPS will be carried out using the 
SP1 FAS.

Sample size calculation 
The sample size for this study is based on an expected difference of zero and common SD of 
1.30 for the DAS28-CRP change from baseline at Week 12 (ReAct study), an equivalence 
margin of 0.6and assumed loss of 20% patients from the per-protocol analysis set. A 0.6 change 
in DAS28-CRP score is considered as the minimum clinically meaningful difference by 
EULAR criteria and is therefore used as the equivalence margin limits [0.6,-0.6]. 
In order to fulfil FDA regulatory requirements for establishing therapeutic equivalence (e.g. 
using 90% confidence interval), a sample size of 154 patients per treatment group (to maintain

overall 246 evaluable patients for the primary endpoint analysis) will have 95% power to test 
the equivalence between GP2017 and US-licensed Humira®. 
In order to fulfil EMA regulatory requirements for establishing therapeutic equivalence (e.g. 
using 95% confidence interval), a sample size of 154 patients per treatment group (to maintain 
overall 246 evaluable patients for the primary endpoint analysis) will have 90% power to test 
the equivalence between GP2017 and US-licensed Humira®. 
9.7 Power for analysis of critical secondary variables 
From Burmester et al (2014) the standard deviation at 6 months, i.e. roughly Week 24, was 
calculated as 1.5. This compares with the value of 1.3 found for the Week 12 assessment (see 
Section 9.6). However, it is difficult to estimate the common SD for the AUEC because this 
will depend on the correlation between the DAS28 values for the same subject at different visits. 
Assuming the correlation lies between 0 and 1, then common SD values between around 0.7 to 
1.4 seem likely. Figure 9-1 below shows the resulting power for different values of the common 
SD with 246 evaluable patients when calculating both a 90% and 95% confidence interval. It is 
clear that there is always sufficient power (80%) to demonstrate equivalence using the 90% 
confidence interval, and that the power will also most likely be sufficient using the 95% 
confidence interval.

Ethical considerations 
10.1 
Regulatory and ethical compliance 
This clinical study was designed and shall be implemented 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 Code of Federal Regulations Title 
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 patients may only be included in the study after providing written (witnessed, where 
required by law or regulation), IRB/IEC/REB-approved informed consent, or, if incapable of 
doing so, after such consent has been provided by a legally acceptable representative of the 
patient. In cases where the patient’s representative gives consent, the patient should be informed 
about the study to the extent possible given his/her understanding. If the patient 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. any of the procedures described in the protocol). 
The process of obtaining informed consent should be documented in the patient source 
documents. 
The sponsor 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 the sponsor before submission to the IRB/IEC/REB, and a 
copy of the approved version must be provided to the sponsor (or CRO working on behalf of 
the sponsor) after IRB/IEC/REB 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 and up to 70 days after the end of study. If there is any question that the patient will 
not reliably comply, they should not be entered in the study. 
The “Information for female partners of male study participants” document should be given to 
male participants as part of the informed consent process with the request that they share it with 
their female partners. In case a partner of a male study participant becomes pregnant during the 
study, consent of the pregnant partner should be sought to collect information about the 
pregnancy, the birth and health of the baby. 
 
10.3 
Responsibilities of the investigator and IRB/IEC/REB 
The protocol and the proposed informed consent form must be reviewed and approved by a 
properly constituted IRB/IEC/REB before study start. A signed and dated statement that the 
protocol and informed consent have been approved by the IRB/IEC/REB must be given to the 
sponsor or delegated CRO before study initiation. 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 monitors, auditors, other 
designated agents of the sponsor or CRO, IRBs/IECs/REBs, and regulatory authorities as 
required. If an inspection of the clinical site is requested by a regulatory authority, the 
investigator must inform the sponsor or designated CRO immediately that this request has been 
made. 
 
10.4 
Publication of study protocol and results 
The sponsor assures that the key design elements of this protocol will be posted in a publicly 
accessible database such as clinicaltrials.gov. Study results containing primary outcome 
measure will be published on clinicaltrials.gov within 12 months of primary completion date 
(defined as the date when all study patients have completed Week 12/ EoS (Visit 16) whichever 
is earlier). After finalization of the study report, the results of this trial will be submitted for 
publication and posted in a publicly accessible database of clinical trial results. 
 
11 
Protocol adherence 
Investigators will apply due diligence to avoid protocol deviations. Under no circumstances 
should the investigator contact the sponsor or its representatives monitoring the trial to request 
approval of a protocol deviation, as requests to approve deviations will not be granted, except 
when necessary to eliminate immediate hazards to the subjects. 
This protocol defines the study objectives, the study procedures and the data to be collected on 
study participants. Under no circumstances should an investigator collect additional data or 
conduct any additional procedures for any research related purpose involving any 
investigational drugs. 
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 the 
sponsor and approved by the Heath Authority where required, and the IRB/IEC/REB it cannot 
be implemented. All significant protocol deviations will be recorded and reported in the Clinical 
Study Report. 
 
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 the sponsor, Health Authorities where required, and the IRB/IEC/REB. 
Only amendments that are required for patient safety may be implemented prior to Health 
Authority and 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 patient included in this study, even if this action represents a deviation from the 
protocol. In such cases, the sponsor should be notified of this action and the applicable 
IRB/IEC/REB should be informed as required per local regulations.

Appendix 1: Clinically notable laboratory values 
The following criteria will be used to define expanded limits and notable abnormalities of key 
laboratory tests. 
Clinically notable values will be forwarded to the Sponsor at the same time that they are sent to 
investigators by Central Laboratory. 
Clinically notable laboratory values should be documented as AE if the laboratory change has 
been confirmed by 3 repeated measurements at subsequent per-protocol visits. In subjects who 
already had abnormal laboratory parameters (eg CTC AE grade 1) at screening, laboratory 
change to CTC AE grade 2, confirmed by 3 repeated measurements should be considered 
clinical relevant and documented as AE. At the discretion of investigator, a laboratory change 
can be considered an AE already prior to confirmation by 3 repeated measurements.

Appendix 2: American College of Rheumatology (ACR) Measures 
• The following 66/68 joints will be assessed for tenderness and swelling 
• Number of tender joints: 
The 68 joints to be examined for tenderness are: temporomandibular (2), sternoclavicular (2), 
acromioclavicular (2), shoulder (2), elbow (2), wrist (2), metacarpophalangeal (10), thumb 
interphalangeal (2), distal interphalangeal (8), proximal interphalangeal (8), hip (2), knee (2), 
ankle mortise (2), ankle tarsus (2), metatarsophalangeal (10), interphalangeal of great toe (2) 
and proximal/distal interphalangeal of the toes (8). 
• Number of swollen joints: 
The 66 joints to be examined for swelling are the same as those examined for tenderness, 
except the hip joints are not included. 
• Patient's assessment of RA pain 
On a 100 mm non-anchored visual analog scale, from no pain to unbearable pain. 
• Patient's global assessment of disease activity 
On a 100 mm non-anchored visual analog scale, from no arthritis activity to maximal arthritis 
activity, after the question "Considering all the ways your arthritis affects you, draw a line on 
the scale for how well you are doing". 
• Physician's global assessment of disease activity 
On a 100 mm non-anchored visual analog scale, from no arthritis activity to maximal arthritis 
activity. 
• Health Assessment Questionnaire disability index – HAQ-DI©

Appendix 3: FACIT Fatigue Scale 
Below is a list of statements that other people with your illness have said are important. By 
circling one (1) number per line, please indicate how true each statement has been for you 
during the past 7 days. 
FACIT-Fatigue Subscale Scoring Guidelines (Version 4) 
Instructions:* 
1. Record answers in "item response" column. If missing, mark with an X 
2. Perform reversals as indicated, and sum individual items to obtain a score. 
3. Multiply the sum of the item scores by the number of items in the subscale, then divide by 
the number of items answered. This produces the subscale score. 
4. The higher the score, the better the QOL.
