Trial Design 
 
Overview:   
 
This is a national multicentre, interventional, double-blinded, placebo-controlled, parallel design trial 
of golimumab in combination with MTX versus MTX monotherapy, in MTX naïve psoriatic arthritis 
patients with active dactylitis. We expect to include 136 patients, which will be centrally randomized 
to active and placebo treatment, carried out in a 1:1 manner. 
This trial will include patients older than 18 years, with the diagnosis of psoriatic arthritis according to 
the CASPAR criteria, and ≥1 tender dactylitis, refractory to at least two systemic NSAIDs, at optimal 
dosage, for 3 months.  
 
Duration of Participation:  Each subject will participate in the trial for a maximum of 
approximately 32 weeks from the time the subject signs the Informed Consent Form (ICF) 
through the final contact. After a screening phase of approximately 28 days, each subject will 
receive assigned treatment for 6 months. After the end of treatment, each subject will be

followed for safety monitoring and sustained efficacy assessment for 60 days. 
 
Duration of Trial:  This trial will have the duration of approximately 2 years since the first 
subject signing informed consent to last contact with last subject, at end of the trial. 
 
Key Inclusion/Exclusion Criteria:   
Inclusion criteria: Patients older than18 years, with the diagnosis of PsA according to CASPAR 
criteria, established at least 3 months prior to screening, with ≥1 tender dactylitis refractory to at 
least two systemic NSAIDs, at optimal dosage, for 3 months, willing to give informed consent. 
Exclusion criteria are those considered for any antiTNF agent and MTX or that might interfere 
with trial evaluations or patient’s safety. 
 
INVESTIGATIONAL PRODUCT, DOSE, MODE OF ADMINISTRATION 
Investigational Product:  Golimumab, a fully human monoclonal antibody, administered at a 
subcutaneous (SC) dose of 50 mg, once monthly, preferably on the same day of every month.  
Reference Product:  placebo  
 
Both golimumab and placebo will be administrated in association with MTX at a dose between 
10 mg and 25mg/weekly. 
 
STATISTICAL METHODS:   
 
Data Set(s) to be Analyzed:  The evaluable population will consist of those subjects who 
received at least one dose of golimumab/placebo plus MTX and have dactylitis severity score 
(DSS) calculated at baseline and at least one post-baseline visit. All safety analyses will be 
performed on all subjects who received at least one dose of golimumab or placebo plus MTX. 
 
Sample Size:  Considering a dropout rate of 20%, it is expected that a total of 136 patients need 
to be randomized to achieve primary endpoint. 
 
Efficacy Analysis:  All efficacy data will be analyzed according to assigned treatment group.  
Descriptive statistics will be used to summarize all primary dactylitis severity score (DSS) and 
secondary endpoints such as LDI, LEI, SPARCC, PsAMRIS-H and PsAMRIS-F, tender 68 and 
swollen 66 joints, patients and physician global assessment VAS, target NAPSI, BASDAI,BASFI, 
HAQ-DI, composite indexes of disease activity, SF36 and DLQI. Comparison between treatment 
groups will be made by T-student test (or Mann-Whitney, if normality assumption is not verified). 
The Qui-square test (or Fisher exact test) will be used to compare the proportion of patients 
achieving DSS, LDI, ACR, PSARC, PASJAI, PASI, ASAS and ASDAS responses and MDA. 
 
Safety Analysis:  Adverse events will be analyzed and the incidence summarized by the total 
number of patients in each treatment group experiencing a given event.  
 
Interim Analysis:  An interim analysis is planed when 50% of the patients have been included.

6.0 BACKGROUND AND RATIONALE 
Psoriatic arthritis (PsA) is a pleomorphic chronic inflammatory arthritis with a broad 
clinical spectrum, ranging from peripheral arthritis to axial spondylitis, enthesitis, 
dactylitis and uveitis, in association with psoriasis and nail dystrophy. Dactylitis and 
enthesitis are core manifestations that occur clinically in 30 to 50% of PsA patients, 
often in early disease.[1] Dactylitis is additionally an unfavorable prognostic factor 
associated with erosive disease and its relevance is further supported by its inclusion in 
the classification criteria for psoriatic arthritis (CASPAR) [2-3].  
The clinical assessment of dactylitis and enthesitis has although limitations, as for 
dactylitis scarce correlation between clinical and imaging finding has been shown and 
the prevalence of enthesitis is underestimated in comparison with ultrasound and 
magnetic resonance imaging (MRI) findings. [2] The complementary use of imaging 
tools is therefore of fundamental importance to improve the characterization of these 
manifestations and to discriminate between responders and non responders to 
therapy. Because disease activity severity has been proven to be similar in the early 
phases of spondyloarthritis (nosologic group in which PSA is included) in comparison 
with established disease, both in observational cohorts and more recently in clinical 
trials, prompt treatment of dactylitis and enthesitis, which are often early and severe 
manifestations, is of fundamental importance to reduce the impact of the disease in 
patient’s quality of life. [4-7]  
 
When considering available therapies methotrexate (MTX) is recommended by the 
European League Against Rheumatism (EULAR) as the preferential treatment for 
patients with active peripheral disease that do not respond to non steroidal anti-
inflammatory drugs and local corticosteroids injections, if indicated. [8]  Due to a large 
experience with the use of MTX, generally good tolerability, low cost and its 
concomitant benefits on skin lesions, this is also the gold standard practice in our 
country. MTX as well as other commonly used first line synthetic disease modifying 
anti-rheumatic drugs (DMARDs), such as leflunomide and sulfassalazine, lack however 
evidence based proof of efficacy in the treatment of both dactylitis and enthesitis. [8-
9]  
 
All tumor necrosis factor inhibitors (TNFi) approved for PsA (infliximab, adalimumab, 
etanercept and golimumab) have demonstrated efficacy both for skin and joint 
involvement, as well as preventing joint damage. In particular infliximab, golimumab 
and etanercept have also shown efficacy in randomized controlled trials in improving 
clinically assessed dactylitis and enthesitis but only as secondary endpoints.[10]  
Both EULAR and Portuguese guidelines consider the use of TNFi in the management of 
dactylitis and enthesitis but the final decision to introduce a TNFi is based on the 
general clinical judgment of the treating physician. [8, 11] When considering predictors 
of response both shorter disease duration and enthesitis, among others, are associated 
with better response to TNFi in prediction models [12] Furthermore in a clinical setting 
TNFi were more efficacious in inhibiting radiographic progression in PsA patients in 
comparison with MTX.[13] 
The treatment algorithm for dactylitis and enthesitis is therefore still debatable, as it is 
evidenced by the lowest level of agreement in EULAR recommendations, highlighting a

need to increase available randomized controlled trials data to improve clinical care 
[8]. 
Golimumab, a human TNFi monoclonal antibody, has well documented efficacy in 
improving dactylitis and enthesitis.[14] Effects on dactylitis and enthesitis have 
although been reported only as secondary outcomes in the GO-REVEAL study, with the 
golimumab 100mg arm showing significantly greater improvement for dactylitis scores 
and both golimumab 50mg and 100mg arms showing also significantly larger 
improvement for enthesitis scores at 24 weeks. [14-15]  
The concept that, in opposition to what is observed in rheumatoid arthritis trials, the 
association of MTX to TNFi in psoriatic arthritis would not bring additional benefits 
seems to be changing and applicable only to MTX non-responders patients. [8] In fact, 
recent results from the GO-REVEAL trial, at week 52, suggest that adding MTX to 
golimumab is associated with a further improvement of 10% in dactylitis, enthesitis 
and nail psoriasis scores.[16] Additionally the RESPOND trial supports that in MTX 
naive patients MTX might potentiate the effect of infliximab. [17] In addition it has 
been demonstrated that MTX treated patients have lower production of anti drug 
antibodies. [18-19]  
Taking these data together we hypothesized that a better understanding of the 
therapeutic effect of golimumab in association with MTX, in comparison with MTX 
monotherapy, will contribute to improve the management of dactylitis and enthesitis. 
This evaluation will be empowered by the use of sensitive imaging tools such as MRI.  
We therefore expect that the results from this trial will bring new insight into PsA 
pathogenesis and the positioning of golimumab in combination of MTX and MTX 
monoterapy, in dactylitis and enthesitis treatment algorithm.

8.0 TRIAL DESIGN  
This is a national multicentre, interventional, double-blinded, placebo-controlled, 
parallel design trial of golimumab in combination with MTX versus MTX monotherapy, 
in MTX naïve psoriatic arthritis patients with tender dactylitis. We expect to include 
136 patients, centrally randomized to golimumab 50mg or to placebo arms both in 
combination with MTX. The subgroup of patients with concomitant active enthesitis 
will also be separately analyzed. 
 
8.1 
Beginning and End of the Trial 
Each subject is considered to be enrolled in the trial when the subject has provided 
written informed consent.

Each subject is considered to have ended participation in the trial when he/she has 
completed the last protocol-specified contact (eg, visits or telephone contacts) or 
prematurely discontinues from the trial. 
A subject is considered to have discontinued after he/she has withdrawn consent or 
has been discontinued under the conditions specified in Section 9.4 
A subject is considered to have been lost to follow-up if he/she is unable to be 
contacted by the investigator.  The end of participation for a subject lost to follow-up is 
the last known contact (eg, visit or telephone contact). 
The overall trial begins when the first subject is enrolled (ie, signs the informed 
consent form). The overall trial ends when the last remaining subject has ended 
participation in the trial, by completing the trial, being discontinued from the trial, or 
being lost to follow-up. 
Each subject will be monitored for the occurrence of AEs immediately after the subject 
has signed informed consent through 60 days after the last dosing visit. Follow-up 
procedures related to pregnancy or serious adverse events (SAEs) may continue beyond 
the end of the clinical trial. 
All the treatments provided during the trial are approved and available to patients 
after finishing the trial, according to the physician decision based on disease activity. 
Each subject will participate in the trial for approximately 224 days (32 weeks) from 
the time the subject signs the Informed Consent Form (ICF) through the final protocol-
specified contact.  After a (screening) phase of up to 28 day (4 weeks) each subject will 
receive assigned treatment (Section 11) for approximately 168 day (24 weeks).  After 
the end of treatment, each subject will be followed for safety monitoring for 28 days (4 
weeks).

9.4 
Criteria for premature withdrawal 
Patients have the right to withdraw from the study at any time for any reason. There 
should be an attempt to have all patients complete the end of trial visit as detailed in 
the flowchart. 
When applicable, patients should be informed of circumstances under which their 
participation may be terminated by the investigator without the patient’s consent. The 
investigator may withdraw patients from the study in the event of intercurrent illness, 
adverse events, treatment failure, lack of compliance with the study and/or study 
procedures (e.g., dosing instructions, study visits), or any reason where it is felt by the 
investigator that it is in the best interest of the patient to be terminated from the 
study. The reason(s) for withdrawal must be documented and explained to the patient. 
If the reason for removal of a patient from the study is an adverse event, the specific 
event will be recorded on the CRF. There should be an attempt to follow the patient 
until the event has resolved or stabilized. 
Withdrawal is permanent: once a subject is discontinued, he/she shall not be allowed 
to enroll again. An end of study visit must be performed according to described in 
Section 10, preferable 4 weeks after the last treatment administration. 
At a minimum collect the following information when a subject discontinues: 
1. The reason the subject discontinued; 
2. The date of the last dose of test products from the trial; 
3. The date of the last assessment and/or contact. A follow-up contact (telephone or 
visit) will be arranged as appropriate; 
4. (Serious) Adverse Events ([S]AEs); 
5. Compliance with the test product administration as specified in this protocol; 
6. Final Assessments: 
Every effort should be made to ensure that all procedures and evaluations scheduled 
for the final trial visit are performed. 
7. Retrieve all investigative product and test articles from the subject.  
 
 
9.5 
Replacement of subjects and centers 
 
A patient that discontinues from the trial will not be replaced.

10.0 TRIAL PROCEDURES AND ASSESSMENTS 
 
10.1  VISIT PROCEDURES 
The subjects will be asked to attend a screening visit (Visit 1), 3 visits (visit 2 to 4), one 
end-of-study visit (visit 5) and one follow-up visit (visit 6) for a total of 6 visits during a 
period of 32 weeks (including screening period). 
 
10.1.1 
Screening (visit 1) 
Before any screening procedures take place, potential subjects will be provided with 
written and oral information about the trial and the procedures involved. Subjects will 
be fully informed about their responsibilities and of all the procedures involved in the 
trial, the possible risks and disadvantages of being dosed with the trial product and 
their rights while participating in the trial. 
 
They will have the opportunity to ask questions and time to consider participation. If 
the subjects wish to participate in the trial, they will be asked to sign and date, 
including time point, the most current Institution Review Board (IRB) / Independent 
Ethics Committee (IEC) -approved Informed Consent Form. The form must be signed 
and personally dated, including time, by the subjects as well as by the person who 
conducted the informed consent procedure before any trial-related activities are 
performed. A copy of the signed informed consent will be given to the subject. 
 
Patients must fulfill all the entry and none of the exclusion criteria for participation in 
the study.  
 
A medical history including personal and family history, previous and actual 
medication, will be registered. 
 
Laboratory samples should be collected from the patient early in the screening period 
to allow time for the laboratory results to be available for review by the site for 
eligibility. However, the ECG, chest, hand and feet and axial X-rays can be obtained any 
time before randomization to study medication (see Section 10.2.4 for additional 
details on the ECG and chest X-ray).

The subject will be allocated an ascending four digit subject number through a web 
based system. The assessments and blood samplings will be performed according to 
Section 10.3 the flowchart and recorded in the Case Report Form (CRF). 
 
The Investigator will review all information obtained from the screening procedures.  
 
Screening failures i.e. screened subjects not being in compliance with all criteria, are to 
be excluded and the reason to be recorded in a Screening Failure Log and on a 
Screening Failure Form. 
 
For screening failures, all recorded data will be entered in the CRF, but only data on 
the Screening Failure Form will be entered into the clinical database. At a minimum the 
reason for exclusion must be recorded in the Screening Failure Form.  
 
If the initial screening period of 28 days is exceeded, all screening procedures must be 
repeated, except Hepatitis B and C, and TB testing which only need to be repeated if a 
period of more than 60 days has passed. 
 
10.1.2 
Visits 2 to 4 
Visit 2 (baseline) only: Before any further trial activities are initiated, the inclusion and 
exclusion criteria will be checked. Subjects considered eligible to participate in the trial 
by fulfilling the inclusion criteria and none of the exclusion criteria will be randomized 
to golimumab plus MTX or placebo plus MTX. Subjects not passing the exclusion 
criteria will be excluded from this visit. Subjects may be rescreened at the discretion of 
the investigator. Hands and wrists or feet and ankle MRI will be performed to all 
included patient at baseline. 
 
Visit 3 and 4: Assessments and blood samplings will be performed according to the 
flowchart and sections 5.3.11, and recorded in the CRF. MRI will be repeated up to two 
weeks after week 24 (end of study visit). 
 
Dose administration: Dosing of subjects will be performed as described in Section 11. 
Trial product will be dispensed by Merck Sharp & Dohme (MSD) already labeled with 
randomization numbers. MTX will be given orally in weekly administrations. MTX 
should be started at 15mg/weekly at baseline (week 0), increased to 20mg/weekly at 
week 4 and to 25mg/weekly at week 8 maintaining the dose of 25mg/weekly 
throughout the trial period, except in case of intolerance or toxicity (section 11.1)  
 
Drug accountability will be performed locally and registered at the trial-specific Subject 
IMP Accountability Log.

10.1.3 
End of study visit (visit 5) 
 
The EOS visit (Visit 5) will be the last efficacy assessment visit before leaving the trial. 
The assessments and blood samplings listed will be performed according to and 
recorded in the CRF. 
If a subject is withdrawn from the trial, the Investigator will ensure that the procedures 
for the End of Study visit are followed to the extent possible.  
 
Even if the subject is not able to attend, the End of Study Form, Drug Accountability 
Form and Screening Failure Form must be completed.  
 
After the end of study visit, the patient will be followed according to clinical practice.  
Both golimumab and MTX are available for the treatment of active psoriatic arthritis.   
 
The sponsor will notify the investigator when the study is closed to further patient 
enrollment. 
 
10.1.4 
Follow-up visit (FU) 
The last visit will occur 4 weeks after the end of study visit to perform the last safety 
assessment. This might be performed in presence or through phone contact. 
 
The end of the study will occur when the last patient, last visit occurs (LPLV). The 
LPLV is either the date of the last patient visit of the last patient to complete the study, 
or the date at which the last data point from the last patient, which is required for 
statistical analysis (i.e., key safety and efficacy results for decision making), is received, 
whichever is the later date. 
In addition, the sponsor will notify the investigator if the study is placed on 
administrative hold, or if the sponsor decides to discontinue the study or development 
program. 
 
 
 
10.2 TRIAL PROCEDURES 
 
All clinical assessments including both primary (DSS) and secondary (LDI, LEI, SPARCC, 
tender and swollen joint counts, VAS, target NAPSI, PASI, ACR,ASAS and ASDAS 
responses, etc) outcomes measures will be determined at baseline and at every visit 
for 24 weeks, according to flowchart. MRI will be performed at baseline and week. 
 
 
10.2.1 
Demographic 
Information about date of birth (age), gender and race/ethnicity will be recorded.

recorded on an Adverse Event page. 
 
10.2.3 
Relevant medical history, disease characterization and current 
medical conditions 
Subject history should include information on family history and personal history. 
Relevant medical history and current medical conditions including medication will be 
recorded in the CRF at the screening visit. 
 
 
Obtain smoking history. A comprehensive smoking history will be obtained by the 
investigator at the time of subject’s inclusion into the trial. The following definitions 
will be used: 
• Nonsmoker: a person who never smoked. 
• Current smoker: a smoker who has been smoking for at least 1 year at an 
average of at least one cigarette (or equivalent) per day during that year. 
• Ex-smoker: a person who has stopped smoking for at least 3 months and 
was previously smoking for at least 1 year at an average of at least one 
cigarette (or equivalent) per day during that year. 
 
Subjects who do not fall into these categories will be disregarded from the analysis.

Cigarette consumption will be quantified as the average number of cigarettes per day. 
For current and prior smokers, the number of years the subject was or has been a 
smoker will be obtained, and smoking history will be quantified as pack-years. One 
pack-year is equivalent to 20 cigarettes smoked per day for 1 year. 
 
Register alcohol intake. The following definitions will be used: 
 
 Never drinker 
 Current drinker 
 Ex-drinker 
 
For alcohol consumers the average number of drinks will be quantified. 
 
 
The subtype of psoriatic arthritis according to Moll and Wright classification criteria 
will be recorded.[21] 
- 
DIP joint only  
- 
Asymmetrical oligoarthritis  
- 
Polyarthritis 
- 
Spondylitis 
- 
Arthritis mutilans. 
 
Furthermore date of beginning of symptoms, date of diagnosis as well of any extra-
articular manifestations including uveitis, psoriasis, ungueal dystrophy, dactylitis, 
enthesitis, Crohn disease, ulcerative colitis, non specific colitis and aortitis will be 
recorded.  
 
Any joint or periarticular intervention including corticosteroids injections performed 
previously or during the trial, will be registered in the CRF. 
 
 
Hand, feet and axial radiographs 
 
An antero-posterior radiograph of the hands and feet will be performed to patients 
with peripheral involvement. For those with axial involvement pelvis (antero-
posterior), lumbar and cervical (lateral) radiographs will be performed. 
 
10.2.4 
Safety and tolerability 
 
Electrocardiogram (ECG) 
A standard 12 lead ECGs must be obtained during screening and reviewed by the 
investigator or designee. This can be obtained any time during the screening period, 
preferably after the laboratory and history criteria have been met.

The Investigator must evaluate the ECG recordings and classify them as either: 
“normal”, “abnormal but not clinically significant”, or “abnormal, clinically significant” 
and will note the specific findings that lead to that interpretation.   
Original ECG tracings, appropriately signed, will be archived at study site and must be 
available for monitoring. 
 
Chest Radiograph (CXR) 
The posterior-anterior (PA) CXR can be obtained any time during the screening period, 
preferably after the laboratory and history criteria have been met, and reviewed by 
the investigator or designee. At screening, if a CXR has been taken within the past 90 
days that shows no clinically significant abnormality and there are no signs or 
symptoms suggestive of pulmonary disease that would exclude the patient, then a 
further CXR is not required. 
 
Vital Signs 
Vital signs will be measured at each visit. Body temperature (°C), pulse (beats/min) and 
systolic/diastolic blood pressure (mmHg) will be measured. The blood pressure should 
be measured in a supine position. Any clinically significant abnormalities noted in vital 
signs will be recorded as AEs in the CRF. 
 
Tuberculosis Screening and Treatment 
The screening and treatment for tuberculosis will comply with Portuguese guidelines. 
All patients will be referred to the Pneumology Diagnostic Centers (Centros de 
Diagnóstico Pneumológico-CDP) and exclusion of active tuberculosis and requirements 
for latent tuberculosis treatment will be determined by the pneumologist. After 
assessment a referral letter from the CDP will return to the investigator, registered in 
the CRF and kept in the patient records.  
 
10.3 EFFICACY ASSESSMENT 
 
10.3.1 
Dactylitis assessment 
 
Dactylitis severity score (DSS) 
 
For each finger and toe dactylitis will be assessed in a scale of 0 to 3 ((0 = no dactylitis; 
1 = mild dactylitis, 2 = moderate dactylitis, 3 = severe dactylitis) according to physician 
decision. 
The dactylitis score is calculated as the sum of scores for all 20 digits and thus can 
range from 0 to 60. Scores > 0 indicate the presence of dactylitis.[22] 
To achieve a DSS 20, 50, or 70 responses, at least 20%, 50%, or 70% of improvement 
need to be observed in the DSS score. The percentage of patients achieving DSS20,50 
and 70 will be determined.

Leeds Dactylitis Index (LDI)  
 
The LDI is a quantitative measure for dactylitis that uses a specific instrument to 
determine the diameter of a swollen finger or toe associated with evaluation of local 
tenderness. The clinician marks which fingers are affected on a diagram displaying 
fingers and toes. Circumferences of the affected and contralateral fingers are then 
measured around the proximal phalanx, as close as possible to the web space, using 
either a measuring tape or a precalibrated loop (the tool developed for measuring 
digital circumference is available online at www.mie-uk.com). The clinician then 
squeezes the affected fingers with moderate pressure and documents the patient’s 
response: 0 - no tenderness, 1-tender, 2- tender and winces, and 3 -tender and 
withdraws. The ratio of circumference between an affected finger and the 
contralateral unaffected finger is recorded. If both sides are affected, the 
circumference of the affected finger is compared to normative data supplied in a table. 
The tenderness score (0–3) for a finger with dactylitis is recorded, and a total score is 
generated for each finger. If multiple fingers are affected, each score is added together 
to produce a total for the patient. A difference in digital circumference of 10% is used 
to define a finger with dactylitis.[23] A more recent modification of the LDI (LDI basic) 
replaced the original tenderness grading (0–3) by a binary score reflecting the 
presence or absence of tenderness (1 or 0, respectively) [24]  
The LDI requires a tool to measure digital circumference (available from 
http://rehaboutlet.com, Miami, FL, USA). This tool will be provided to the centers. 
To achieve a LDI 20, 50, or 70 responses, at least 20%, 50%, or 70% of improvement 
need to be observed in the LDI score. 
 
Number of patients with dactylitis 
 
The number of patients with tender and non tender dactylitis will be registered.  
 
Dactylitis remission 
 
Dactylitis remission is defined as a dactylitis severity score equal to zero. 
 
10.3.2 
Enthesis assessment 
Leeds Enthesitis Index (LEI) 
 
Tenderness on examination is recorded as either present (1) or absent (0) for each of 
the 6 sites, for an overall score range of 0–6. The 6 evaluated sites are the lateral 
epicondyle, the medial femoral condyle and the Achilles tendon insertion, all both on 
left and right sides. [25] 
 
SPARCC (SpA Research Consortium of Canada) enthesitis score 
 
The SPARCC (SpA Research Consortium of Canada) enthesitis score evaluates 16 
enthesis sites: humerus medial and lateral epicondyle, supraspinatus insertion into 
greater tuberosity of humerus, greater trochanter, insertion of plantar fascia and

Aquilles tendon into the calcaneum, quadriceps insertion into superior border of 
patella and patellar ligament insertion into inferior pole of patella or tibial 
tubercle.[26] The modified version includes the greater trochanter, the Achilles tendon 
and the plantar fascia insertions. 
 
Enthesitis remission 
Enthesitis remission is defined by the absence of tender enthesis according to the LEI 
score. 
 
 
10.3.3 
Joint assessment 
 
Tender and swollen joints 
 
Tender and swollen joints 
 
The 68 tender and 66 swollen joints counts will be evaluated. The joints assessed for 
tenderness included the distal interphalangeal of the hands, proximal interphalangeal 
and metacarpophalangeal joints of the hands, and metatarsophalangeal joints of the 
feet, the wrist joints, the elbows, shoulders, acromioclavicular, sternoclavicular, hip, 
knee, talo-tibial, and mid-tarsal joints. All of these except for the hips are assessed for 
swelling. Joint tenderness and swelling are graded as present (1) or absent (0). The 
assessment of tender and swollen joints are performed according to the EULAR hand 
book[27]

This measure contains 20 items divided into 8 domains: dressing and grooming, arising, 
eating, walking, hygiene, reach, grip, and common daily activities. Subjects rate the 
degree of difficulty they have had in the past week on a 4-point scale, ranging from 0 
(no difficulty) to 3 (unable to do). The highest scores in each category are summed (0–
24) and divided by the number of categories scored to yield a score from 0–3.  
 
10.3.6 
Axial disease assessment 
 
The assessment of axial disease will be applied only to patients with axial involvement 
as determined by the investigator. 
 
Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) 
The BASDAI consists of a one through 10 scale (one being none and 10 being very 
severe), which is used to answer 6 questions pertaining symptoms of AS: 
1. Fatigue 
2. Spinal pain 
3. Joint pain / swelling 
4. Areas of localized tenderness (called enthesitis, or inflammation of tendons and 
ligaments) 
5. Morning stiffness duration 
6. Morning stiffness severity 
To give each symptom equal weighting, the mean (average) of the two scores relating 
to morning stiffness is taken. The resulting 0 to 50 score is divided by 5 to give a final 0 
– 10 BASDAI score.  
 
Ankylosing Spondylitis (AS) Disease Activity Score (ASDAS) 
The AS Disease Activity Score (ASDAS) is a composite disease activity instrument that 
measures disease activity state using an algorithm comprising assessment of back pain, 
morning stiffness duration, joint pain/swelling, patient global disease activity 
assessment, and CRP as follows: ASDAS = 0.1216*Back pain + 0.0586*Duration 
morning stiffness + 0.1106*Patient global + 0.0736*Peripheral pain/swelling + 
0.5796*Ln(CRP+1). Clinically important and major ASDAS improvements are defined as 
a decrease of ≥1.1 and ≥2.0 units, respectively. ASDAS <1.3 is the threshold for an 
inactive disease state.  
 
Bath Ankylosing Spondylitis Functional Index (BASFI) 
The BASFI is a set of 10 questions designed to determine the degree of functional 
limitation in those patients with AS. The ten questions were chosen with a major input 
from patients with AS. The first 8 questions consider activities related to functional 
anatomy. The final 2 questions assess the patients’ ability to cope with everyday life. A 
10cm visual analog scale is used to answer the questions. The mean of the ten scales 
gives the BASFI score – a value between 0 and 10. 
 
ASAS (Assessment in SpondyloArthritis) 20 and 40 
The ASAS (Assessment in SpondyloArthritis) core set (1-6) consists of the following

10.3.7 
Psoriasis assessment 
 
Body Surface Area (BSA) score 
 
BSA score will be calculated for all patients. The BSA score indicates the percentage of 
body surface that is affected considering that the patient’s handprint (palm and 
fingers) correspond to 1% of the body.  
 
Psoriasis Area Severity Index (PASI) 
 
The PASI will be used for patients with psoriasis affecting ≥3% of body surface. 
The PASI assesses the extent of psoriasis on four body surface areas (head, trunk and 
upper and lower limbs) and the degree of plaque erythema, scaling and thickness. [28] 
The PASI score accounts for the extent of body surface area affected by the erythema, 
scaling and thickness and the severity of these measures. The score ranges from 0 (no 
disease) to 72 (maximal disease). The response PASI 50, 75 and 90 will be assessed. 
 
 
10.3.8 
Nail assessment 
 
Target Nail Psoriasis Severity Index (target NAPSI) 
 
In this system the most severely affected nail at baseline is divided into 4 quadrants 
and 1 point is awarded for each nail matrix and 1 point for each nail bed changes, per 
quadrant, ranging from 0 to 8 points per quadrant and a maximum total score of 32. 
Nail bed changes include: onycholisis (separation of nail bed), splinter hemorrhages 
(small dark brown linear marks under the nail), hyperkeratosis (thickened nail keratin), 
and oil-drop dyschromia (reddish-brown discoloration under the nail plate). Nail matrix 
psoriasis includes pitting (sharply defined depressions in the nail surface), leukonychia 
(white spots in the nail plate), crumbling, and red spots in the lunula. [29]

The DLQI is a 10-item questionnaire with answers based on a 4-point Likert scale. 
Responses of “not at all,” “a little,” “a lot,” and “very much” are available for each 
question, and correspond to scores of 0, 1, 2, and 3, respectively. A response of “not 
relevant” is also offered for select questions. 
 
Medical Outcomes Study Short Form 36 (SF-36) 
The SF-36 is a patient questionnaire assessing 8 domains of health status: physical 
functioning (PF), pain, vitality, social functioning, psychological functioning, general 
health perceptions, and role limitations due to physical and emotional problems (70). 
It also can be subdivided into 2 summary scores, the physical and mental component 
scores. 
 
 
10.3.10 Composite indexes 
Psoriatic Arthritis Disease Activity Score (PASDAS)  
This score uses an algorithm comprising assessment of the physician global VAS, 
patient global VAS, physical component of SF-36, swollen and tender joint counts, 
Leeds enthesitis count, tender dactylitis score and CRP.  [30] 
 
Composite Psoriatic Disease Activity Index (CPDAI) 
Disease is assessed in up to 5 domains: peripheral joints, skin, enthesial, dactylitis, and 
spinal involvement. For each domain, individual instruments are used to assess the 
extent of disease activity as well as the impact on patient function and health-related 
quality of life. Domains are scored from 0–3, with empirical cutoffs for disease 
severity/activity proposed in each largely based on the literature (Table 3). Individual 
domain scores are summed to give an overall composite score (range 0–15).[31] 
Disease Activity Index for Psoriatic Arthritis (DAPSA)  
This index measures disease activity using the 68 tender and 66 swollen peripheral joint 
counts, patient global VAS, patient pain VAS, and C-reactive protein (CRP). The composite 
score is a simple sum of the scores.[32] 
  
 
Disease Activity Score (DAS28)  
DAS28 will be calculated based on assessments of the following 28 joints for 
tenderness and swelling: metacarpophalangeal I-V (10), thumb interphalangeal (2), 
hand proximal interphalangeal II-V (8), wrist (2), elbow (2), shoulders (2), and knees 
(2).[33]

The SDAI is the numerical sum of five outcome parameters: tender joint count (28 
joints assessment), swollen joint count (28 joints assessment), CRP in mg/dl, patient’s 
global disease activity on a 0-10 cm VAS, and physician’s global assessment on a 0-10 
cm VAS.[34] 
Clinical Disease Activity Index (CDAI) 
The CDAI includes the same components as SDAI except CRP. [35] 
American College Rheumatology response 20, 50 and 70   
To achieve an ACR 20, 50, or 70 response, at least 20%, 50%, or 70%, respectively, 
improvement in tender and swollen joint counts and three of five scores of individual 
elements (VAS scores of patient pain, physician and patient global assessment, a 
disability measure (HAQ) and an acute phase reactant (ESR or CRP)) must be obtained 
without worsening of the other two.  
 
Psoriatic Arthritis Response Criteria (PSARC)  
 
To achieve a PSARC response, a patient has to achieve 2 of the following, one of which 
has to be a tender (68) and swollen (66) joint count, and no worsening of any measure: 
tender or swollen joint count improvement of 30% and/or patient global or physician 
global improvement of at least 1 point on a 5-point Likert scale.[36] 
 
Psoriatic Arthritis Joint Activity Index (PSAJAI) 
 
The PsAJAI is the weighted sum of 30% improvement in 6 measures with weights of 2 
given to tender joint count, C-reactive protein (CRP) level, and physician global 
assessment of disease activity. Weights of 1 are given to the remaining 30% 
improvement measures, including pain, patient global assessment of disease activity, 
and Health Assessment Questionnaire [37]

10.3.12 MRI assessment 
 
MRI of the wrists and hands or the feet and ankle will be performed at baseline and 
week 24 depending on dactylitis location. If both hand and feet fingers are involved 
the most severely affected area will be selected.  
 
Protocol 
MRI examination will be performed on a 1.5-T device.  
 
The following sequences will be acquired before intravenous injection: T1-weighted 
fast spin-echo sequences on the sagittal and coronal plane, proton density weighted 
fast spin-echo sequence with fat saturation on the sagittal and coronal plane and T1-
weighted 3D Fast Field Echo. 
Intravenous injection of gadolinium will be performed using an automatic injector at a 
standard dose of 0.1 mmol/kg (0.2 mL/kg) with a flow rate of 2.5 mL/s through a 20-G 
Abbocath® needle into a cubital vein. After injection, e-THRIVE dynamic sequence 
acquired  with repeated acquisitions starting post-contrast will be reconstructed in the 
axial plane. T1-weighted fast spin-echo sequences with fat saturation on the axial and 
sagittal planes after contrast injection were also be acquired. [11] 
 
 
Definitions 
The MRI sets will be scored in respect to synovitis, erosions, tenosynovitis, soft tissue 
oedema, bone marrow oedema, according to the definitions of the OMERACT / 
PSAMRIS-H method that was developed for assessing hands of psoriatic arthritis 
patients, with the necessary adaptations to the territories of the feet and ankle under 
analysis for development of PSAMRIS-F.[40] Additionally enthesitis, enthesophytes and 
dactylitis will be recorded. Bone erosion will be defined as a bone defect with sharp 
margins, visible in 2 planes. Bone erosion lesion will be scored from 0 to 10 by the 
volume of the erosion as a proportion of the “assessed bone volume” by 10% 
increments judged on all available images. For the tarsal bones, the “assessed bone 
volume” will be the whole bone. For long bones, the “assessed bone volume” will be 
from the cortex of the articular surface to a depth of 1 cm. Bone edema will be defined 
as a lesion with ill-defined margins that have high signal intensity on T2-weighted 
sequences. Each bone will be scored separately (as for erosions). The scale will be 0–3 
based on the proportion of bone with edema, as follows: 0, no edema; 1, 1%–33% of 
bone edematous; 2, 34%–66% of bone edematous; and 3, 67%–100%. Synovitis will be 
defined as the area in the synovial compartment that shows enhancement of a 
thickness greater than the width of the joint capsule after gadolinium. The scale will be 
0–3. Score 0 is normal, and 1–3 (mild, moderate, severe) are by thirds of the presumed 
maximum volume of enhancing tissue in the synovial compartment. Enthesitis will be 
defined as intrasubstance and peri-enthesis contrast enhancement and the scale will 
be 0-3 by thirds of the presumed maximum volume of enhancing tissue. Enthesis bone 
erosion and edema will be defined as already described. Tenosynovitis will be scored 
on a 0-3 scale on the basis of thirds of the presumed volume of maximal synovial tissue 
enhancement. Soft tissue oedema will be registered as present or absent. Dactylitis 
will be scored separately according to previous described and published system by

Healy et al, 2008. Each feature will be scored as present/absent at each of three levels 
of the digit: metacarpophalangeal joint, proximal inter-phalangeal joint and distal 
inter-phalangeal joint: synovitis (capsular enhancement and intracapsular fluid), bone 
oedema, subcutaneous oedema, flexor tenosynovitis (peritendinous fluid and 
enhancement), extensor tenosynovitis (peritendinous fluid and enhancement), 
plantar/volar plate enhancement, collateral ligament enhancement and erosions. In 
addition, the presence of sesamoiditis at the thumb and great toe will be assessed. An 
MRI score will be developed for each digit with one point allocated for the presence of 
each feature at each joint level and a total score obtained by the simple summation of 
these features (maximum score for each of the second through fifth digits, 24; for the 
first digit, 17). [41]  
 
The region of interest (ROI) for the dynamic study will be selected on the basis of the 
unequivocal synovial tissue that shows a progressive enhancement on the 
reconstruction of the axial and coronal planes of the different dynamic acquisitions 
and the tissue that exhibits maximum visual enhancement. We will use a small area 
(20–30 mm2) while avoiding intra-articular fluid as identified by pre-contrast and 
dynamic sequences.  
 
 
MRI reading will be performed by two trained musculoskeletal radiologists with 
experience on the PSAMRIS score. The enhancement ratio of the synovial tissue will be 
calculated in 2 ways: (1) as the rate of early enhancement during the first 57 s 
according to the formula REE57 = S57/S200, where S57 and S200 are the signal 
intensity 57 and 200 s after gadolinium injection, respectively; and (2) as the relative 
enhancement (RE) according to the formula RE = S200 – S0. [8]

Hepatitis and HIV  
All subjects will be screened for Hepatitis B surface antigen (HBsAg), antiHBs and 
antiHBc antibodies. 
Screening for Hepatitis C will be based on HCV antibodies.  
Evaluation for HIV seropositivity will be performed, and, if positive, confirmation by a 
second technique available at the laboratory site, e.g., Western blot. 
Results will be available as source data and will not be recorded within the CRF. 
 
Pregnancy test 
Any female aged 18 years and above is considered a woman of child bearing potential 
(WoCBP), and must be included among female subjects undergoing obligatory 
pregnancy testing. Pregnancy tests are required for all female subjects regardless of 
reported sterilization. Serum pregnancy test (bHCG) will be performed at screening.  
The result of the pregnancy tests at screening must be received before the subject 
receives the first administration of study treatment.

All subjects will be tested at screening for the presence of surface antigen Human 
Leukocyte Antigen (HLA) B27, encoded by the B locus in the major histocompatibility 
complex class I, rheumatoid factor and for anti-cyclic citrullinated peptides antibodies. 
 
 
10.3.13.2 Standard clinical laboratorial parameters 
Venous blood will be drawn for routine blood tests and as part of the safety panel at 
the investigational sites. 
Any clinically significant abnormalities noted in laboratory test values will be recorded 
as AEs in the CRF. 
Unscheduled laboratory assessments for safety issues are permitted at any time.  
The total volume of blood loss for laboratory assessments will be approximately (40 
mL).  
All laboratory tests for standard clinical assessment will be performed locally at each 
center lab. 
 
The following laboratory analyses will be performed as outlined in the flowchart. 
On dosing day all labs are to be obtained prior to administration 
of study medication. 
 
Hematology/CBC: Hemoglobin, hematocrit, RBC and indices (MCV, MCH, MCHC), 
WBC & absolute differential, platelet counts. 
Blood Chemistry: Creatinine. Urea, uric acid, random glucose, potassium, sodium, 
chloride, calcium, phosphorous, total protein and albumin will just be collected at 
screening. 
Lipid Panel: Fasting total cholesterol, triglycerides, HDL, LDL, just at screening. 
Liver Profile: AST/SGOT, ALT/SGPT. Alkaline phosphatase and total bilirubin (direct and 
indirect will be performed if total bilirubin >ULN), just at screening. 
Acute Phase Reactants:  CRP and ESR (using Westergren method). 
Urinalysis: Type II urine including microscopic examination. 
 
10.3.13.3 Immunogenicity 
Anti-golimumab antibodies will be assessed in serum by venopuncture at the same 
moment as for standard clinical laboratorial parameters. 
 
Collection of blood samples: For each scheduled immunogenicity sample, 2 mL blood 
will be drawn into a plain barrier tube to obtain 1 mL serum. Enzyme-linked 
immunosorbent assay (ELISA) will be used for determinations.

11.0 TREATMENTS 
11.1 Trial Treatments  
The investigator shall take responsibility for and take all steps to maintain appropriate 
records and ensure appropriate supply, handling, storage, distribution, and usage of 
these materials in accordance with the protocol and any applicable laws and 
regulations. 
 
MSD will provide adequate clinical supplies to dose approximately 136 subjects 
throughout the 6 months length of the trial. The clinical supplies will be labeled in 
accordance to local regulations.  
Storage of the clinical supplies will be in accordance with the clinical supply label. 
 
The following trial products will be supplied by MSD: 
 
• 
Golimumab 50mg/ 0.5 ml in a pre-filled syringe.  
• 
Placebo 0mg/ 0.5 ml sterile solution in a pre-filled syringe. 
 
The golimumab 50 mg and placebo pre-filled syringes are indistinguishable from each 
other: no difference in the appearance of the two solutions is detectable.  
 
Golimumab or placebo will be administrated subcutaneously, once a month, for 6 
successive months.  
 
MTX will be started at dose of 15mg/week, increased to 20mg/week at week 4 and 
aiming at 25mg/week at week 8, according to patient tolerability. A minimum dose of 
MTX 10mg/week is required in order to keep the patient in the trial. 
 
MTX will be taken orally, once a week, for 6 successive months. Folic acid will be given 
at least 24 hours after MTX intake, at a dose between 5 and 25mg according to the 
investigator.  
 
The following actions should be considered in case of suspicion of myelotoxicity:

The first dose of the investigational product will be administered at the trial site at 
Visit 2 by a trial nurse. Patient education for self administration will be performed as in 
current clinical practice. Subsequent dosing will be done once a month by self 
administration by the patient . The patients will receive both golimumab and placebo 
subcutaneously in association with methotrexate.  Patients will be further contacted 
by phone to ensure compliance to trial medication.  
 
Packaging and labeling of trial products 
Labeling and packing the trial products will be performed by MSD in accordance with 
local law and trial requirements. 
 
Pre-filled syringes will be labeled according to randomization numbers and sent to trial 
sites. Trial product will be packed in non subject specific boxes and sent to the site 
according to requirements. 
 
Dispensing 
The investigator or qualified designee(s) will dispense trial treatments at the 
designated site(s) to subjects who have provided written informed consent and have 
met the entry criteria.  Clinical supplies may not be used for any purpose other than 
that which is stated in this protocol. 
 
Storage and drug accountability of trial product 
Trial treatment supplies must be stored in a secure, limited-access location under the 
storage conditions specified on the supply label. Site storage conditions should be 
monitored by the site personnel for adherence to label specifications and reviewed 
during site visits. 
 
Accurate and current accounting of the dispensing and return of investigational 
product(s) will be maintained on an ongoing basis by a member of the trial site staff: 
Investigational medicinal product(s) dispensed to each site will be recorded in the trial-
specific Site Investigational Medicinal Product (IMP) Accountability Log.  
Investigational medicinal product(s) dispensed to each subject will be recorded in the 
trial-specific Subject IMP Accountability Log (or equivalent document approved by 
the sponsor). 
 
The Site IMP Accountability Log and Subject IMP Accountability Log will be verified by 
the trial monitor. The original Site IMP Accountability Log and Subject IMP 
Accountability Log will be approved by the investigator and retained at the trial site 
and a copy supplied to MSD when the trial is complete.

The syringes will be discarded by the trial nurse immediately after return by the 
patient at every visit. 
The trial monitor will instruct the site on the return of all investigational product(s) 
supplies.  A final inventory of the total amount of investigational product(s) received at 
each trial site against the amount used and destroyed must be recorded in the Site 
IMP Accountability Log.  Inventory records must be readily available for inspection by 
the trial monitor and/or auditor, and open to government inspection at any time. 
 
11.2 Selection and Timing of Dose for Each Subject 
Golimumab selected dose and frequency of administration is the one approved for 
psoriatic arthritis treatment.  
11.3 Determining the Timing of Dose Administration for Each Subject 
There are no special requirements for the timing of the golimumab doses in relation to 
time of day, meals, or concomitant medications.  
Golimumab will be administered according to the dosing schedule explained in 
flowchart allowing a window of ±7 days. In case a golimumab dose is administered 
outside this window and if the investigator agrees that the subject can remain in the 
trial, then the day of that month when golimumab was administered will become the 
new target day for subsequent administration, again with a ±7-day window. 
The same criterion shall be used if a golimumab dose must be delayed for safety 
reasons. 
 
11.4  Non-Trial Treatments 
Prior, Concomitant  and Rescue Medications 
Medications, Supplements, and Other Substances Prohibited Prior to Baseline and 
During the Trial 
A subject must not have received any investigational drugs within the 
30 days prior to Baseline, and must not receive them during the current trial. 
Patients cannot have been previously treated with MTX.  
 
Concomitant Medications, Supplements, and Other Substances Allowed During the 
Trial 
No other DMARDs (with the exception of MTX) or oral corticosteroids are allowed 
during the trial.  
During the conduct of the trial, the physician is allowed to use intra-articular injections 
of corticosteroids as rescue medication, with exception of hand and feet joints. The 
injection, if deemed necessary, should occur at least 4 weeks prior to the next

scheduled examination. Joints that are injected with corticosteroids must be counted 
as tender and swollen at each visit falling within 4 months after the injection. The use 
of this rescue medication should be documented as such in the CRF and will be subject 
to secondary endpoint analysis. 
For patients that show gastrointestinal intolerance to oral MTX switching to 
subcutaneous formulation can be considered. 
Subjects are allowed to take analgesics as rescue medication.  
The dose and frequency of all rescue medications needs to be registered in the CRF. 
 
Subjects should be advised not to take an analgesic medication within 6 hours prior to 
the visits for dactylitis, joint and enthesis, evaluation.  
 
Any concomitant medications (including over-the-counter medications, herbal 
medications, preventative vaccines, vitamins and food supplements) and procedures 
must be recorded in the eCRF. A description of the type of drug or procedure, the 
amount, duration, reason for administration of drug or procedure, and the outcome of 
any procedures must be documented. Adverse events related to the administration of 
a concomitant medication or the performance of a procedure must also be 
documented on the appropriate AE page of the eCRF.  
If concomitant medication it’s changed because of abnormal laboratory values of 
clinical significance, side effects, concurrent illness, or performance of a surgical 
procedure. The reason for change must be clearly documented in the subject’s medical 
record. Note that the use of any concomitant medication must relate to the 
documented medical history, prophylaxis, or an adverse event (AE) of the subject. 
 
11.5 Procedures for monitoring subject compliance with administration 
of trial treatments 
At all protocol-specified visits, the investigator or qualified designee is to record 
whether treatment had been taken per protocol in the preceding interval.  If not, the 
date(s) and reason for each dosing noncompliance must be recorded. 
 
12.0 TRIAL SCHEDULE 
 
This trial is planned to be started in December 2013 and its first subject first visit (FSFV) 
planned for January 2014. The recruitment period is estimated in 18 months. The 
planned data for completion of the last subject last visit (LSLV) is December 2015 and 
the end of the trial in January 2016.

This trial will be conducted as a randomized double-blinded trial, with centralized 
allocation and randomization to active and placebo treatment, carried out in a 1:1 
manner. During randomization patients must always be assigned to the lowest 
randomization number, which will be used through the trial.  
No stratification based on age, sex, or other characteristics will be performed. 
 
Randomization will be performed using a web based system and randomization 
numbers will be sent to MSD. Golimumab and placebo syringes will be labeled 
according to randomization numbers.  
 
Both golimumab and its matching placebo will be identical in appearance and will be 
packaged identically. Neither the subject nor the investigational staff (investigator, 
pharmacist, nurse and evaluators) will know which treatment the subject is receiving. 
 
The blinding should be kept for all staff involved in the trial related activities, until the 
trial is completed and the database is released for statistical analysis. 
 
Subjects who drop out will not be replaced. 
 
 
13.1 Breaking of blinded codes 
The subject’s code may be broken in a medical emergency, if knowing the identity of 
the treatment allocation would influence the treatment of the subject.  
 
If the trial site needs to break the code, the principal investigator should, if possible, be 
contacted prior to breaking the code.  
 
Whenever a code is broken, the person breaking the code must record the time, date 
and reason as well as his/her initials in the source documents. In all cases, the monitor 
must be notified within 24 hours after the code has been broken. 
 
All other individuals directly involved in this study will remain blinded until the final 
analysis of the primary parameter. 
 
 
14.0 STATISTICAL AND ANALYTICAL PLAN 
The blinding of the randomized subjects will be maintained until the database has 
been released for statistical analysis. The official clinical database will not be unblinded 
until clinical/scientific review has been completed, protocol violators have been 
identified (if appropriate) and data is declared complete. 
 
The principal investigator and co-investigators will be responsible for the analysis of 
trial data with exception of those for interim analysis.

14.1 Sample size calculation 
We expect that approximately 40% of the psoriatic arthritis patients followed/referred 
to rheumatology centres will have tender dactylitis.  
 
For sample size calculation we used ps: power and sample size calculation program.  
 
Assessment of dactylitis severity score: this will be a study of controls and 
experimental subjects in a proportion of 1 control(s) per experimental subject.  From 
the GO-REVEAL trial data the response within each subject group was normally 
distributed with a standard deviation of 4.8.[14] If the true difference in the 
experimental and control means is 2.6, we will need to study 108 patients (54 
experimental subjects and 54 control subjects) to be able to reject the null hypothesis 
that the population means of the experimental and control groups are equal with 
probability (power) 0.8.   The Type I error probability associated with this test of this 
null hypothesis is 0.05.  
Considering a dropout rate of 20% before week 24, 108/(1-0.2)= 135, it is expected 
that approximately 136 patients are required to be included to achieve primary 
endpoint.  
 
 
14.2 Statistical methods 
Categorical variables will be summarized by frequency and percentage.  
Continuous variables will be summarized by mean, median, standard deviation, and 
interquartile range. 
 
An intention to treat analysis will be performed including all randomly assigned 
patients who received at least one dose of study medication and have at least one 
efficacy and safety post-treatment assessment. 
 
14.2.1 
Baseline characteristics 
All demographic, disease characterization, previous medical history, previous and 
current therapies, current medical history among other variables will be listed by 
treatment group and subject. For these parameters summary statistics will be provided 
by treatment group.  
  
 
14.2.2 
Efficacy endpoints 
All efficacy data will be analyzed according to assigned treatment group.  
 
Primary efficacy endpoints

T-student test (or Mann-Whitney, if normality assumption will not be verified) will be 
used to compare means for dactylitis severity score  between treatment groups. The 
mean change of score and respective standard deviations will be calculated and 
comparison between treatment groups will be made by T-student test (or Mann-
Whitney, if normality assumption is not verified). 
 
Effect estimation will be made by differences between treatment mean scores and will 
be adjusted for eventual non-homogenous baseline characteristics. 
 
 
Secondary efficacy endpoints 
 
Descriptive statistics will be used to summarize all secondary endpoints such as LDI, 
LEI, SPARCC,  PsAMRIS-H and PsAMRIS-F, tender 68 and swollen 66 joints, patients and 
physician´ VAS, BASDAI, ASDAS, BASFI, target NAPSI, HAQ-DI, SF36, DLQI and 
composite indexes among others by treatment group. The mean change of score and 
respective standard deviations will be calculated and comparison between treatment 
groups will be made by T-student test (or Mann-Whitney, if normality assumption is 
not verified). 
 
The Qui-square test (or Fisher exact test) will be used to compare the proportion of 
patients achieving DSS20,50,70, ACR20,50,70, PASI75,90, ASDAS clinical important and 
major improvements, ASAS20,40, MDI responses among others. 
 
MRI  
 
MRI reading will be performed by two blinded trained musculoskeletal radiologists 
with experience on the PSAMRIS score. Inter-reader and intra-reader agreements will 
be calculated. 
Descriptive statistics of each lesion for individual joints, dactylitis and enthesis, and 
aggregated scores by region will be calculated.  The data will be analyzed individually 
by joint and lesion and as aggregated scores. Pairwise comparisons between two time 
points for each individual joints, dactylitis and enthesis and for aggregated scores by 
region will be calculated. 
 
 
14.2.3 
Interim analysis 
One interim analysis is planned when 50% of the estimated sample size (68 patients) is 
achieved and data will be reviewed by an independent data monitoring committee 
(IDMC). The levels of significance will be calculated according to O’Brien-Fleming 
stopping boundaries using EAST software.

The safety analysis population will include all patients who receive at least one 
golimumab/placebo dose and had at least one post-dose safety assessment. All safety 
parameters will be summarized and presented in tables based on this safety 
population. Adverse events will be analyzed and the incidence summarized by the total 
number of patients in each treatment group experiencing a given event. Patients will 
be assigned to treatment groups as treated.  
 
 
 
 
 
 
15.0 ADVERSE EVENTS 
15.1 Definitions and reporting 
A. For purpose of this Protocol the below terms shall be defined as follows: 
 
“Adverse Event” or “AE” shall mean any untoward medical occurrence in a Study 
subject who is administered the Study Drug regardless of whether or not a causal 
relationship with the Study Drug exists. By way of example and without limitation, an 
AE can be any unfavorable and unintended sign (for example, an abnormal laboratory 
finding), symptom, or disease temporally associated with the use of the Study Drug,  
 
“Serious Adverse Event” or “SAE” shall mean any untoward medical occurrence in a 
Study subject who is administered the Study Drug that results in death, a life-
threatening drug experience, requires inpatient hospitalization or prolongation of 
existing hospitalization, results in persistent or significant disability/incapacity, or is a 
congenital anomaly/birth defect, cancer, or is a new cancer if the cancer is the 
condition of the study, or overdose. Other important medical events that may 
jeopardize the patient or may require intervention to prevent one of the outcomes 
listed previously should also be considered “serious”. 
 
“Suspected Unexpected Serious Adverse Reaction” or “SUSAR” shall mean any 
Serious Adverse Event, the nature, severity or frequency of which is not consistent 
with information in the most current investigator’s brochure, or with respect to a 
marketed product the most current Summary of Product Characteristics (SPC) or 
Package Insert. 
 
B. Serious Adverse Event and Suspected Unexpected Serious Adverse Reaction 
Reporting:  Principal Investigator forwards to MSD’s Global Safety (“MSD”) group, any 
SAE and SUSAR information, including, but not limited to, all initial and follow-up 
information involving any Study subject in the Study.  Notification is made in the form 
of a completed CIOMS I within one (1) business days of learning of the SAE or SUSAR.  
This SAE and SUSAR information is transmitted to MSD using the contact information 
provided below or such other modified contact information as provided by MSD in 
writing.  All SAE and SUSAR information is transmitted in the English language and 
contains the reporter’s name and the Study subject identifier code.   SUSAR

relevant parties the Development Safety Update Reports (DSUR) according to the 
applicable legislation. The Principal Investigator also forwards the final DSUR to MSD. 
 
H. In the event Principal Investigator or Institution becomes aware of a defect or 
possible defect in the Study Drug, Institution and Principal Investigator notify MSD 
within one business day of first becoming aware of the possible defect.   
 
I. Principal Investigator notifies MSD within twenty-four (24) hours in the event that 
any regulatory authority notifies the Study site of a pending inspection/audit that 
concerns the Study or Institution’s ability to perform clinical research.  In addition, 
Principal Investigator forwards to MSD any written communication received as a result 
of the inspection/audit within twenty-four (24) hours of receipt of such 
communication and allows MSD to assist in responding to any citations involving the 
Study Drug.  Such responses shall be made as soon as possible under the 
circumstances or within any earlier deadline set by the issuing regulatory authority. 
Principal Investigator also provides to MSD copies of any documents provided to any 
inspector or auditor.  In the event the regulatory authority requests or requires any 
action to be taken to address any citations, Principal Investigator and Institution agree, 
after consultation with MSD, to take such action as necessary to address such 
citations. 
 
J. MSD may provide the Sponsor and Principal Investigators, at Study initiation and on 
an ongoing basis, with information regarding the Study Drug, including but not limited 
to safety information.  The Sponsor and Principal Investigators agree to hold this 
information in confidence. 
 
 
Overdose 
An overdose is a significant variation from the recommended/scheduled dosage for a 
product. In this current trial an overdose of the investigational product golimumab is 
any dose higher than the doses specified in Section 6 of this protocol for subcutaneous 
administration. Single doses of golimumab up to 10 mg/kg body weight IV have been 
administered in a clinical trial without dose-limiting toxicity. In case of an overdose of 
golimumab that exceeds the normal monthly dosing regimen, it is recommended that 
the patient be monitored for any signs or symptoms of adverse effects and appropriate 
symptomatic treatment be instituted immediately. 
 
Product Quality Complaint

A product quality complaint (PQC) is any written, electronic or oral communication 
that alleges a product defect. A PQC includes suspected product counterfeit, diversion 
or tampering. A PQC does not include Product Complaints alleging an AE. 
 
Planned Hospitalization 
A hospitalization planned by the subject prior to signing the ICF is considered a 
therapeutic intervention and not the result of a new SAE and should be recorded as 
medical history. If the planned hospitalization or procedure is executed as planned, the 
record in the subject’s medical history is considered complete. 
However, if the event/condition worsens during the trial, it must be reported as an AE. 
 
 
Medication Error 
A medication error is any preventable event that may cause or lead to inappropriate 
medication use, including unintended accidental exposure or subject or patient harm 
while the medication is in the control of a health care professional, subject or patient, 
or consumer. Such events may be related to professional practice, clinical trials, health 
care products, procedures, and systems, including prescribing, order communication, 
product 
labeling, 
packaging, 
and 
nomenclature; 
compounding, 
dispensing, 
distribution, administration, education, monitoring, and use. 
 
Potential Medication Error 
A potential medication error is an individual case safety report of information or 
complaint about product name, labeling, or packaging similarities that does not involve 
a subject or patient (eg, if a subject reports that one of the investigational products 
looks like a different product, the report would be considered a potential medication 
error). 
 
Trial Procedure Related Events 
A clinical trial procedure related event is an AE that could be associated with the trial 
procedures, rather than the investigational product or its administration. 
Trial procedures include all treatment procedures and medical procedures for physical 
examinations, medical investigations, and laboratory assessments or other activities 
specified in the protocol for the purpose of the clinical trial. 
 
 
15.2 Monitoring 
Monitoring Adverse Events 
Subjects will be monitored for the occurrence of SAEs immediately after the subject 
has signed informed consent. Subjects enrolled in the study will be monitored for both 
AEs and SAEs. 
Subjects will be questioned and/or examined by the investigator or a qualified 
designee for evidence of AEs. The questioning of subjects with regard to the possible 
occurrence of AEs will be generalized such as, "How have you been feeling since your 
last visit?” The presence or absence of specific AEs should not be elicited from 
subjects. 

GO-DACT                                                 Confidential   
V2.0_05_12_2013 
 
 
EudraCT 2013-000643-40 
 
48 
 
Subjects having AEs will be monitored with relevant clinical assessments and 
laboratory tests, as determined by the investigator. 
 
AEs, actions taken as a result of AEs, and follow-up results must be recorded in the 
CRF, as well as in the subject's source documentation. Follow-up laboratory results 
should be filed with the subject's source documentation. 
For all AEs that require the subject to be discontinued from the trial and SAEs, relevant 
clinical assessments and laboratory tests will be repeated as clinically appropriate until 
final resolution or stabilization of the event(s). 
 
 
 
Monitoring Laboratory Assessments 
Assessments of laboratory parameters including CRP, RF, and anti-CCP, HLAB27, ESR 
will be performed locally. These laboratory values will be reported to the investigator 
by the laboratory and he/she will review them for significance and consideration as an 
AE.  
 
15.3 Assessment of Adverse Event 
Assessment of Severity 
Where the determination of AE severity rests on medical judgment, the determination 
of severity must be made with the appropriate involvement of a medically-qualified 
investigator. 
The severity of AEs will be graded according to the following definitions: 
Mild: awareness of sign, symptom, or event, but easily tolerated; 
Moderate: discomfort enough to cause interference with usual activity and may 
warrant intervention; 
Severe: incapacitating with inability to do normal daily living activities or significantly 
affects clinical status, and warrants intervention; 
 
Assessment of Causality 
A medically qualified investigator must assess the relationship of any AE (including 
SAEs) to the use of the investigational product, as unlikely related, possibly related, or 
probably related, based on available information, using the guidelines listed below: 
 
Unlikely related: no temporal association, or the cause of the event has been identified 
and attributed to other disease or drug; or the drug, biologic, or device cannot be 
implicated based on available information; 
Possibly related: temporal association, but other etiologies are likely to be the cause; 
however, involvement of the drug, biologic, or device cannot be excluded based on 
available information; 
Probably related: temporal association, other etiologies are possible, but unlikely 
based on available information.

CONSIDERATIONS 
The trial must be conducted in accordance with Good Clinical Practice (GCP) as 
outlined in the International Conference on Harmonization of Technical Requirements 
for Registration of Pharmaceuticals for Human Use (ICH) Guidelines, E6 Good Clinical 
Practice:  Consolidated Guidance and other applicable laws and regulations.  In 
addition, the trial must be conducted in accordance with the European Union (EU) 
Clinical Trial Directive (CTD) and local regulations.   
16.1 Ethical Conduct of the Trial 
16.1.1 
Independent Ethics Committee or Institutional Review Board 
Prior to initiation of the trial at any site, the trial, including the protocol, informed 
consent, and other trial documents must be approved by an appropriate IRB/IEC.  The 
IRB/IEC must be constituted according to applicable regulatory requirements.  As 
appropriate, amendments to the protocol must also be approved by the IRBs/IECs 
before implementation at the sites, unless warranted to eliminate an immediate 
hazard.  The IRB/IEC approval should be obtained in writing, clearly identifying the 
trial, the documents reviewed (including informed consent), and the date of the 
review.  The trial as described in the protocol (or amendment), informed consent, and 
other trial documentation may be implemented only after all the necessary approvals 
have been obtained.  
In the event that the IRB/IEC requires changes in the protocol, the sponsor shall be advised 
and must approve the changes prior to implementation.  The investigator shall not modify the 
trial described in the protocol once finalized and after approval by the IRB/IEC without the 
prior written approval of sponsor. 
 
16.1.2 
Subject Information and Consent 
The details of the protocol must be provided in written format and discussed with each 
potential subject, and written informed consent must be obtained for all subjects 
before any trial-related procedure is performed.  In obtaining informed consent, the 
information must be provided in language and terms understandable to the subject.  
The subject, or the subject's legal representative, must give their written consent to 
participate in the trial.  The signed and dated consent form itself must be retained by 
the investigator as part of the trial records.  A copy of the signed and dated consent 
form must be given to the subject.  The consent form must include all of the required 
elements of informed consent in accordance with ICH Guidelines E6 and local laws.   
The consent form must be approved by the appropriate IRB/IEC and sponsor before 
trial initiation at a trial site.  Any subsequent changes to the approved informed

consent form must be reviewed and approved by the appropriate IRB/IEC and sponsor 
before implementation. 
16.1.3 
Subject Identification Card 
A Subject Identification Card is provided to each subject to carry on his or her person 
(eg, in a wallet) at all times while the subject is participating in the trial.  The Subject 
Identification Card must be provided to the subject no later than when IMP is 
dispensed.  The card is to be shown to caregivers in the event of an emergency. 
At a minimum, the card must contain the following information: 
1. Protocol number; 
2. The subject’s protocol identification number; 
3. A statement identifying the card-carrier as a participant in a clinical trial (eg, 
“This person is participating in a clinical research trial.”); 
4. A statement indicating the investigational drug that the patient is receiving 
(eg, “This person is taking an experimental drug or placebo”); and 
5. Contact information in the event of an emergency or hospitalization.  The 
contact information on the card is to be the investigator or a designated site 
contact. 
 
Monitors will request that Investigators provide Subject Identification Cards to each 
subject.  Investigators will be asked to request that subjects carry the cards with them 
while they are participating in the trial. 
The Investigator/site should collect the cards at the end of the trial and retain them 
with other clinical trial documents. 
 
16.1.4 
Registration of the Trial 
The trial will be registered on a publicly accessible database – clinicaltrials.gov  
The results will be disclosed on a publicly accessible database- clinicaltrials.gov 
 
16.2 Reporting Trial Data  
16.2.1 
Data Collection Forms 
The Rheumatic Disease Portuguese Register (reuma.pt), developed for the registry of 
all patients undertaking biologics in Portugal will be used as electronic case report 
form. The reuma.pt is approved by Comissão Nacional de Proteção de Dados (CNPD). 
This is a web based register with restricted access by password attributed to 
investigators. Specific fields for this trial were developed and only accessed by trial 
investigators. The trial monitor will equally have access to required clinical data.

The investigator must maintain records and data during the trial in compliance with all 
applicable legal and regulatory requirements.  Each data point must be supported by a 
source document at the trial site.  Any records or documents used as the source of 
information (called the “subject source data”) are to be retained for review by 
authorized representatives of the sponsor or a regulatory agency. 
The investigator will ensure that there are sufficient time, staff, and facilities available 
for the duration of the trial to conduct and record the trial as described in the protocol 
and according to all applicable guidances, laws, and regulations. 
All data collection forms (eg, CRFs, diaries; EDC screens), electronic database entries, 
etc, should be completed as soon as possible after the evaluation has occurred.  All 
dates appearing on subject data collection forms for laboratory tests, cultures, and 
other data collected, must be the dates on which the specimens were obtained, or the 
procedures performed. 
16.2.2 
Preparing Case Report Forms for All Subjects 
A CRF must be completed for all subjects who have given informed consent.  The 
subject names, initials, or other personal information that is beyond the scope of the 
trial must not be collect from any subject.  Subjects are not to be identified by name or 
initials on the CRF or any trial documents.  The only acceptable identification for a 
subject who may appear on a CRF or trial document is the unique subject identification 
number.  The investigator must maintain contact information for each participant so 
that all can be quickly contacted by the investigator, if necessary. 
All entries into CRFs are the responsibility of the investigator and must be completed 
by the investigator or a qualified designee.  Ensure that all questions are answered and 
that no empty data blocks exist. Ensure that no information is recorded outside the 
data blocks. The investigator will attest in writing at the beginning of the trial that 
his/her electronic signature is the legally binding equivalent of a written signature and 
will acknowledge by entering his/her electronic signature that he/she has verified the 
accuracy of the recorded data. 
16.2.3 
Preparing Case Report Forms for Subjects Who Fail Screening 
Data are to be collected from the time the informed consent form is signed until the 
subject is determined to have failed screening.  A CRF with a minimum of the following 
information must be completed for subjects who fail screening:  (1) demographics, 
(2) subject status, (3) reason for screen failure, and (4) serious adverse events. 
 
16.2.4 
Publications and Other Rights 
16.2.4.1
