STUDY TITLE 
A 
Multicenter, 
Randomized, 
Double-blind, 
PlacebO-controlled, Parallel-group Study to EValuate the 
Efficacy and Safety of JTE-051 Administered for 12 Weeks 
to Subjects with Active Rheumatoid Arthritis (MOVE-RA) 
PROTOCOL NUMBER AE051-G-13-003 
CLINICAL PHASE 
Phase 2a 
STUDY DURATION 
Approximately 20-week duration per subject: 
• 
Up to a 28-day Screening Period 
• 
A 12-week double-blind (DB) Treatment Period 
• 
Approximately a 4-week Follow-up Period  
STUDY OBJECTIVES 
• To evaluate the clinical efficacy of JTE-051 in subjects 
with active rheumatoid arthritis receiving background 
non-biologic disease-modifying anti-rheumatic drug 
therapy. 
• To evaluate the safety and tolerability of JTE-051 
administered for 12 weeks in subjects with active 
rheumatoid arthritis receiving background non-biologic 
disease-modifying anti-rheumatic drug therapy. 
• To evaluate the pharmacokinetics (PK) of JTE-051 in 
plasma of subjects with active rheumatoid arthritis.  
STUDY DESIGN 
 
This 
is 
a 
multicenter, 
randomized, 
double-blind, 
placebo-controlled, parallel-group, 12-week study in biologic 
and kinase inhibitor treatment-naive rheumatoid arthritis 
(RA) subjects on stable disease-modifying anti-rheumatic 
drug (DMARD) therapy, including methotrexate (MTX). 
Eligible subjects will be randomized at Visit 2 to receive 
JTE-051 50 mg, 100 mg, 150 mg, 200 mg or placebo once 
daily (QD) for 12 weeks. Subjects will continue to receive up 
to two non-biologic DMARDs, including MTX, throughout 
the study (at a stable background dose and route of 
administration for at least 12 weeks prior to Visit 2 and 
throughout the study) and will return for a Follow-up Visit 
approximately four weeks after the last dose of study drug is 
administered. 
Randomization 
will 
be 
stratified 
by 
geographical region and by the screening high-sensitivity 
C-reactive protein (hs-CRP).

NUMBER OF 
SUBJECTS TO BE 
ENROLLED AND 
RANDOMIZED 
A sufficient number of subjects will be screened to ensure 
the randomization (in a 1:1:1:1:1 ratio) of approximately 
250 subjects (50 subjects per treatment group). 
KEY ELIGIBILITY 
CRITERIA 
• 
Males and females, 18 to 75 years of age (inclusive) at the 
time of the Screening Visit; 
• A diagnosis of RA prior to the Screening Visit, based on 
the American College of Rheumatology (ACR)/European 
League 
Against 
Rheumatism 
(EULAR) 
2010 
Classification Criteria; 
• Active disease despite ongoing therapy with up to two 
non-biologic DMARDs, including MTX at both the 
Screening and Baseline Visits (Visits 1 and 2), as defined 
by both: 
 ≥6 out of 68 tender joints AND 
 ≥6 out of 66 swollen joints; 
• Screening hs-CRP ≥1.2 x upper limit of normal (ULN), 
based on the central laboratory values;  
• Background treatment with up to two non-biologic 
DMARDs including MTX (mandatory) and one of the 
following medications (optional): sulfasalazine ≤3 g/day, 
hydroxychloroquine 
≤400 mg/day 
or 
chloroquine: 
≤250 mg/day at the time of the Screening Visit; 
 The MTX dosage must be 15-25 mg/week (or the 
maximum documented tolerated dose for the 
subject, not <10 mg/week) and all background 
therapy must be stable, defined as no change in 
dose or route of administration for ≥12 weeks 
prior to the Randomization Visit (Visit 2). 
• No prior/current exposure to biologic and/or kinase 
inhibitor therapy;

INTRODUCTION 
1.1. 
Background 
1.1.1. Rheumatoid Arthritis 
Rheumatoid arthritis (RA) is a systemic autoimmune disease of unknown cause 
characterized by chronic and persistent joint swelling, joint tenderness and synovial joint 
destruction that leads to pain and disability.1 Approximately 1% of the world’s population 
is considered to be suffering from the disease2 and the number of patients is estimated to 
be approximately 1.3 million in the US.3 Females are more likely to suffer from the 
disease, with a reported ratio of male to female patients of 1:2.5. The disease can occur at 
any age, but it is most common among those aged 40 to 70 years, its incidence increasing 
with age. 
In rheumatoid arthritis, abnormal activation of various inflammatory cells such as T cells 
and macrophages causes and exacerbates chronic synovitis. Patients mostly complain of 
morning stiffness as an initial symptom. The disease is characterized by inflammatory 
findings that involve multiple joints such as those in the fingers, hands and knees, leading 
to the development of pain, swelling associated with synovial fluid retention and local 
warmth. The inflammatory symptoms are mostly experienced in the early stage followed 
by repeated remissions and relapses, which lead to the destruction of cartilage and bone, 
with deformation of the joints over time, finally causing severe dysfunction. When the 
disease is highly active, various clinical symptoms such as general malaise, pyrexia, and 
anemia are observed as non­joint-related symptoms. It is known that these symptoms 
markedly impair the activities of daily life and finally worsen life prognosis. It has been 
reported that insufficient treatment shortens the life of patients with rheumatoid arthritis 
by 10 to 15 years compared with that of healthy individuals.4  
1.1.2. Treatment of Rheumatoid Arthritis 
The treatment of rheumatoid arthritis aims to maintain the physical functions of the 
patients and improve their quality of life (QOL) through control of symptoms and 
prevention of joint destruction.5 To achieve these aims, drug treatments from an early 
stage of the disease based on the background of appropriate nonmedical therapies is 
recommended in US and Europe.6,7 Currently, as therapeutic agents, disease-modifying 
anti-rheumatic drugs (DMARDs), non-steroidal anti-inflammatory drugs (NSAIDs), oral 
use and intraarticular injection of steroids, and biological agents are used. 
Disease-modifying anti-rheumatic drugs that can inhibit progression of the pathological 
conditions play a central role in the treatment. Methotrexate (MTX) is prescribed as the 
standard therapy and immunosuppressive drugs are prescribed as switch or combination 
therapy. Disease-modifying anti-rheumatic drugs alleviate pain and swelling by correcting 
the immune abnormality, but their efficacy is not sufficient, leaving some non-responders 
and those with a reduced response without relief. These drugs may also be able to inhibit 
the joint destruction, but their inhibitory effect on the progression of destruction of the 
cartilage and bone is not sufficient in the absence of remission. Since DMARDs are slow-
acting, it takes a long time to improve the QOL, and the pathological condition may be 
allowed to progress if judgment to change the drug for non-responders is delayed. Since

rheumatoid arthritis has a chronic course, long-term therapies are usually required, 
however, very often, it is difficult to continue sufficient treatment due to adverse events 
(AEs) such as disorders in gastrointestinal tract associated with NSAID use, blood and 
liver AEs caused by DMARDs, as well as osteoporosis associated with steroids. Recently, 
it has been demonstrated that biological agents can quickly alleviate arthritis symptoms 
and suppress progression of joint destruction by selectively inhibiting the action of 
cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6).8-11 However, 
long-term use of biological agents is also problematic, because they have the potential to 
increase the risk of infections and induce serious allergic reactions, are expensive and can 
be administered only by injection. Based on these considerations, new oral therapeutic 
drugs that can quickly alleviate pain and swelling, inhibit the progression of cartilage and 
bone destruction, and are superior to existing drugs in terms of safety, convenience, and 
cost efficiency are desired.  
1.1.3. Interleukin-2-inducible T-cell Kinase 
Interleukin-2-inducible T-cell kinase (ITK) is a non-receptor protein tyrosine kinase that 
is mainly expressed in T cells, mast cells, and natural killer cells. In the T cells, the 
molecule plays a role in transmitting stimulation triggered by the antigen via the T cell 
receptor (TCR) located on the cell membrane.12 When antigen is presented with the major 
histocompatibility complex on the antigen-presenting cells such as dendritic cells and 
macrophages, T cells are activated by recognizing the antigen via the TCR. As a result of 
activation, T cells produce cytokines such as interleukin-2 (IL-2), interleukin-17 (IL-17) 
and interferon γ (IFNγ) and accelerate their own proliferation. It is also considered that 
T cells are significantly involved in the development of tissue inflammation and damage 
by activation of other inflammatory cells by these cytokines. Findings that indicate a 
relationship between ITK and pathological changes have been reported. T cells obtained 
from ITK­knockout mice could not show IL-2 production in response to stimulation 
mimicking antigen presentation, which led to decreased cell proliferation. Cell 
proliferation is also less sensitive in the mixed lymphocyte reaction if obtained from mice 
of a different strain.13 Furthermore, it has been reported that ITK-knockout mice show 
impaired response in allergic airway inflammation induced by the antigen: the production 
of various cytokines in the T cells in lymphoid tissues, the infiltrative inflammatory cell 
counts in the airway, and the secretion of airway mucus.14 This information suggest that 
ITK may be involved in the development of pathological changes in autoimmune 
diseases, transplant rejection and allergic diseases of which the onset and exacerbation are 
caused by an excessive immune response to the antigen.

Justification of Study Population and Dose Selection 
Justification for Study Population 
 
 
Patients with a diagnosis of RA, based on the American College of Rheumatology 
(ACR)/European League against Rheumatism (EULAR) 2010 Classification Criteria23 
(see Appendix 1), that are MTX-insufficient responders, i.e., have active RA (defined by 
the number of tender and swollen joints) despite stable dosing of at least 12 weeks with 
MTX (and up to one additional non-biologic DMARD) will be enrolled in this study (for 
the purpose of the study,  RA patients will be referred to as “subjects” throughout the 
protocol). The inclusion/exclusion criteria and the restrictions set in this study are based 
on its objectives, i.e., to demonstrate the clinical efficacy of the compound and to 
evaluate safety and tolerability of JTE-051 in patients with RA, the stage in development 
(i.e., early Phase 2 study, first to evaluate clinical efficacy in RA) and the 
nonclinical/clinical characteristics of JTE-051, based on the data available to date. Efforts 
have been made to take into account feasibility and enrollment-related considerations 
while maintaining the scientific integrity of the study and minimizing the risks for the 
study subjects. 
Briefly, from an efficacy perspective, study subjects must have not been exposed to 
biologic or kinase inhibitor therapy in order to minimize the variability in the efficacy 
response due to prior exposure to these immunosuppressive/immunomodulator agents in 
this “first-in patient” study. Additionally, in order to be eligible, subjects would have to 
have high-sensitivity C-reactive protein (hs-CRP) levels >1.2 x the upper limit of normal 
(ULN) at study entry, to confirm a sufficient level of disease activity and to allow for an 
adequate evaluation of the primary efficacy parameter (i.e., the ACR20 response rate at 
EOT). Considering other parameters of upmost significance for the evaluation of 
JTE-051’s efficacy, such as ACR50 and ACR70, an hs-CRP cut-off above 1.2 x ULN 
would be ideal from a scientific perspective, however, taking into account feasibility, the 
current value is considered appropriate with the appropriate stratification criteria set in 
place, to ensure a comparable distribution of high vs. lower hs-CRP subjects across 
treatment groups. Minimum of a 12-week stable dosing (with respect to dose and the 
route of administration) for the background MTX and for the other non-biologic 
DMARDs permitted by the protocol is mandatory and restrictions pertaining to the 
anti-inflammatory and anti-pain medications (including corticosteroids and NSAIDs), as 
well as other anti-RA medications administration have been set, in order to ensure that 
the maximum efficacy response to these medications has been attained and that the 
subject is stable by the time of baseline evaluations in this study, and to subsequently

minimize the placebo response, which is known to be significant in studies of similar 
indication. Also, in an attempt to minimize other confounding factors, subjects with 
inflammatory and rheumatic conditions other than RA are prohibited from being 
randomized in the study. 
From a safety perspective, study restrictions were implemented based on the 
 
o
 
i
 
nonclinical and clinical data available to date. These include restrictions aiming to 
minimize the risk to the participating subjects, to minimize the confounding factors in the 
assessment process and to monitor and adequately manage any safety-related findings, as 
they occur. Thus, subjects at high risk of developing immunosuppression-related AEs, 
such as infections or malignancies, including those with pre-existing conditions (e.g., 
clinically-manifest or latent tuberculosis, active infections with hepatitis B or C viruses or 
the human immunodeficiency virus [HIV] infection) or significant hematological 
abnormalities (see Exclusion Criterion # 3) are excluded from participating in the study. 
 
 
 
 
 Other, general safety-related restrictions, such as cardiovascular-system-
related, hepatic and renal function-related restrictions have been implemented, taking into 
account the co-administration with MTX (a medication with known significant hepatic 
and renal-related toxicity), as well as the known safety signals associated with other 
comparable compounds on the market or in development (e.g., hepatic or lipid-related 
signals). The procedures set in place to ensure that the appropriate subjects are 
randomized in this “first-in patient” POC study in subjects with RA, as well as the safety 
management strategies implemented in the study are discussed in the following section: 
“Justification for Study Design”.   
Justification for Study Design 
A parallel group, placebo-controlled, add-on therapy design will be employed in this 
study, to assess the effect of JTE-051 on the efficacy parameters and to evaluate the safety 
of JTE-051, compared to placebo in subjects with active RA. Briefly, upon completion of 
all protocol-mandated screening procedures, the qualified subjects will be randomized at 
Visit 2 in a 1:1:1:1:1 ratio to one of the following five parallel dose groups: JTE-051 
50 mg QD, JTE-051 100 mg QD, JTE-051 150 mg QD, JTE-051 200 mg QD or placebo 
QD (50 subjects to be randomized per arm; see Section 3.8.1.6 for considerations related 
to sample size calculation), and will receive the double-blind (DB) treatment for 
12 weeks followed by a four-week Follow-up Period. The single-dose AE051-U-11-001

study data demonstrated no food effect on the PK of JTE-051; thus, study drug will be 
administered regardless of meals; nonetheless, the protocol requires that the once daily 
study drug administration to occur in the morning, to ensure an approximately 24-hour 
period between dosing, based on the PK characteristics of the compound (see 
Section 1.2.2). The duration of the DB Treatment Period is sufficient to allow for proof of 
efficacy in subjects with RA, as an initial step in development. Following attainment of 
this objective, longer-duration (≥6 months) studies, including open-label extensions, as 
appropriate, are planned. The duration of the Follow-up Period was set to approximately 
four weeks, standard duration for similar out-patient studies administered an 
investigational product. Considering the PK characteristics of JTE-051 (see Section 1.2.1), 
it was determined that this interval is conservative,
 
a
 
The efficacy parameters assessed in this study are consistent with the standards in the 
industry in similar RA trials 
 
 
 Appropriate efficacy analyses are 
planned, as detailed in Section 3.8.3.2. To minimize the chance for errors, all calculations 
of derived parameters will be done by the Sponsor based on the appropriate core data 
points collected and documented by the Investigators. Additionally, although all joint 
evaluators in the study are expected to be rheumatologists with experience in joint 
assessments, adequate training on these assessments is planned, to ensure consistency and 
to minimize intra- and inter-assessor variability. For this reason, the protocol also 
strongly recommends that the same assessor performs the joint counts for a subject 
throughout the study duration. 
With respect to safety, adequate procedures have been implemented to minimize the risks 
to the study subjects (based on the compound’s MOA and the nonclinical and clinical 
data available to date [see Sections 1.2.1 
 for summary information and the 
Investigator’s Brochure for detailed information]) and to facilitate further characterization 
of the safety profile of JTE-051.  
Specifically, 
 
 
 
 screening procedures were set in place to exclude 
subjects at high risk of infections (e.g., medical history, chest radiography and serologic 
screening for tuberculosis, screening for hepatitis B and C, as well as HIV infections) and 
adequate withdrawal criteria, based on the Common Terminology Criteria for Adverse 
Events (CTCAE), see Section 3.4, have been implemented.

With respect to the musculoskeletal AE, considering the underlying disease of subjects in 
this study (i.e., RA), it is expected that musculoskeletal-related signs and symptoms will 
be common; thus, differentiation by the Investigator of the etiology of these events, 
i.e., underlying disease vs. potential other causes will be required. 
 
 
 
 These type of events will be adequately managed through the 
standard AE collection, processing and reporting procedures, per Good Clinical Practice 
(GCP) and all actions to ensure the safety of the subjects will be taken by the study 
investigators. Additionally, the CTCAE withdrawal criteria will be applied to all AEs 
reported in the study. 
 
 
 
 
 
 The safety data obtained after the completion for the study will facilitate a better 
understanding of the compound’s safety profile as a stepping stone in the next stage of 
development.    
Justification for Dose Selection 
The selection of JTE-051 doses in this study is based on the collective data from 
nonclinical pharmacology/toxicology studies and Phase 1 clinical studies.

INVESTIGATIONAL PLAN 
3.1. 
Number of Sites and Subjects 
Multiple sites will be employed to ensure screening of sufficient number of subjects to 
randomize (in a 1:1:1:1:1 ratio) approximately 250 subjects (50 subjects per treatment 
group). 
3.2. 
Study Design 
This is a multicenter, randomized, double-blind, placebo controlled, parallel-group, 
12-week study in biologic and kinase inhibitor treatment-naive RA subjects on stable 
background non-biologic DMARD therapy, including MTX. 
Eligible subjects will be randomized at Visit 2 to receive JTE-051 50 mg, 100 mg, 
150 mg, 200 mg or placebo once daily for 12 weeks. Subjects will continue to receive up 
to two non-biologic DMARDs, including MTX throughout the study (at a stable 
background dose and route of administration for at least 12 weeks prior to Visit 2 and 
throughout the study) and will return for a Follow-up Visit approximately four weeks 
after the last dose of study drug is administered. Randomization will be stratified by 
geographical region and by the screening hs-CRP. 
The study duration will be of approximately 20 weeks per subject: 
• Up to a 28-day Screening Period 
Note: Certain pre-defined exceptions that would allow for a longer duration of 
the Screening Period to ensure a 28-day pre-randomization stabilization of 
concomitant medications are permitted, as described in Section 3.5.4.1.

Removal of Subjects from the Study 
A subject will not participate further in the study under the following conditions: 
1. 
Withdrawal by Subject: subjects have the right to withdraw from the study at any 
time. However, if a subject withdraws consent because of experiencing an adverse 
event, the reason for subject termination should be documented as the adverse event. 
2. 
Adverse Event: a clinical or biological adverse event or intercurrent condition(s), 
requiring study drug discontinuation, whether or not related to the study drug 
If grade 3 findings (defined as severe or medically significant but not immediately 
life-threatening; hospitalization or prolongation of hospitalization indicated; 
disabling; limiting self-care activities of daily living [ADL] such as bathing, dressing, 
undressing, feeding self, using the toilet, taking medication, but not bedridden), 
according to the CTCAE25, are noted in a subject, he/she must be promptly evaluated 
by the Investigator (including repeat tests, evaluation of the baseline parameters, 
concomitant medications, etc.) for potential withdrawal from the study. Every effort 
should be made to discuss with the study’s Medical Monitor prior to final decision, 
unless not feasible, based on safety considerations. Subjects who interrupted study 
drug administration due to a grade 3 CTCAE finding may be re-started on therapy if 
the event has resolved and it is considered appropriate by the Investigator and 
Sponsor or designee. 
Notes:  
• The investigator may decide to evaluate or withdraw the subject from the study 
based on findings of lesser than grade 3 severity, according to his/her judgment. 
 
3. 
Consistent* Non-compliance with Study Drug (i.e., <80% or >120% compliance; 
exceptions  on a case-by-case basis may be permitted if approved by Sponsor or 
designee) 
*Determined at >1 study visit during the Treatment Period. If compliance of 
<80% or >120% is identified at a study visit, the Investigator or designee is to 
counsel the subject and ensure steps are taken to improve compliance.

a. The target day for each visit timepoint will be calculated relative to the date of 
Randomization Visit (Visit 2) and not relative to the date of the previous visit. All visits 
should be performed within the windows specified in the table. Every attempt should be 
made to have the subject attend each visit as scheduled. The investigational site is 
encouraged to a make a reminder phone call to the subject approximately a day or two before 
the scheduled visit. However, if a subject is unable to attend a visit within the specified

windows, the visit should be scheduled as closely as possible to these windows. A subject 
should not skip a protocol-specified visit due to scheduling difficulties. 
 
c. Unless a chest radiography had been performed within 3 months (12 weeks) of the 
Screening Visit, and documentation is available for review by the Investigator and inclusion 
in the subject’s file. 
d. At Visit 1 serum pregnancy test will be performed; at all other visits, urine pregnancy tests 
will be performed. Pregnancy tests may also be repeated as needed or per request from 
IRBs/IECs or if required by local regulations. 
e. Rheumatoid Factor 
f. Anti-cyclic citrullinated peptide antibodies 
g. At Visit 2, a back-up drug blister card will be dispensed to all subjects, in addition to the 
regular study drug blister cards. Subjects will be instructed not to use the back-up blister card 
unless all drug in the regular blister cards has been used and to bring all used and unused 
(including back-up) blister cards to each study visit for accountability purposes. At Visit 6, 
study drug will not be dispensed. If a study subject discontinues study drug prematurely, the 
appropriate systems will be accessed to record termination as soon as possible after the 
decision has been made. 
h. Study drug compliance will be calculated by the site at each visit during the Treatment 
Period starting at Visit 3, based on the number of tablets dispensed/returned by the subject. 
The subject is to maintain the back-up blister card for the duration of the Treatment Period. 
i. 
Oral administration for 12 weeks starting on the day of randomization at Visit 2, QD in the 
morning, regardless of meals. On study visit days, subjects should take their scheduled study 
treatment from their existing study drug supply (if available) at the site, under the 
supervision of the investigator or designee after all study-related procedures have been 
performed (except for Visit 6, when no study drug will be administered, as the last dose will 
be taken the day prior to the visit). If no tablets from the previously supplied non-back-up 
blister cards are available, then the subject should dose from the new blister card supplied at 
that visit. Following completion of accountability and compliance assessments, the back-up 
blister card will be re-dispensed at Visits 3 through 5 and will be collected at Visit 6 along 
with all non-back-up drug blister cards. The back-up blister card should only be utilized by 
subjects if all study drug from the regularly-supplied (i.e., non-back-up) blister cards has 
been used. 
j. 
Adverse event information will be collected at the specified time points as well as at any 
time when a clinical research unit staff member becomes aware of an AE after the subject 
signs the informed consent for the study. However, stable or improving pre-existing 
conditions that are detected through the screening procedures throughout the 
Screening Period (e.g., abnormalities in ECG, physical examination, 
 
 vital signs, and laboratory tests) are considered to be medical history and 
should be documented accordingly.

3.5.1. Screening Period 
Day -28 (Visit 1) to Day 1 (Visit 2) 
Following signature of the Informed Consent for the study, screening procedures to 
confirm eligibility may be performed across multiple days, as needed, during the 
Screening Period. If a subject arrives for a visit not having fasted (overnight fast, at least 
10 hours prior to blood and urine sample collection), all study procedures with the 
exception of the blood/urine collection activities may be performed; the subject’s 
remaining procedures will be rescheduled for blood/urine collection on a subsequent day 
within the visit window and he/she will be reminded to fast overnight.  
Please refer to Table 1 for the list of screening procedures to be performed in the study. A 
one-time repeat of the screening laboratory (except for drugs of abuse and alcohol, viral 
serology and pregnancy tests), vital sign and ECG assessments is permitted, if considered 
appropriate by the Investigator, except if stated otherwise (e.g., an up to a three-time 
repeat of blood pressure measurements at the Screening Visit is permitted). The repeat 
test(s) results are to be utilized for subject qualification purposes. If the repeat test results 
are outside the protocol-required range, the subject should be excluded from the study.  
Re-screening of subjects may be permitted on a case-by-case basis, pending discussion 
and approval by the medical monitor. 
3.5.2. Double-blind Treatment Period 
Day 1 (Visit 2) to Day 84 ±2 (Visit 6/Week 12) 
Please refer to Table 1 for the by-visit list of procedures to be performed in the study 
during this period.  
All visits during the Double-blind Treatment Period (i.e., including Visit 2 
[Randomization Visit]), should be performed under fasted conditions (overnight fast, at 
least 10 hours prior to blood and urine sample collection). If a subject arrives for a visit 
not fasted, then all study procedures with the exception of the blood/urine collection 
activities may be performed; the subject’s remaining procedures will be rescheduled for 
blood/urine collection on a subsequent day within the visit window and he/she will be 
reminded to fast overnight. Exception to this would be Visit 2 (Randomization Visit), at 
which all study procedures have to be completed within the same session, therefore, if the 
subject is not fasted, the full visit should be rescheduled. 
All visits should be performed within the windows specified in the table. Every attempt 
should be made to have the subject attend each visit as scheduled. The investigational site 
is encouraged to a make a reminder phone call to the subject approximately a day or two 
before the scheduled visit. However, if a subject is unable to attend a visit within the 
specified windows, the visit should be scheduled as closely as possible to these windows. 
A subject should not skip a protocol-specified visit due to scheduling difficulties.

Clinical Study Protocol AE051-G-13-003 
Subjects will be administered the first dose of study drug in the clinical research center, 
upon completion of all pre-dosing procedures and randomization at Visit 2; subsequently, 
they will be instructed to self-administer study drug once daily, in the morning, regardless 
of food. However, subjects should not take study drug in the morning of the day of a 
study visit until after all study procedures have been completed. On those days study drug 
will be administered at the site by the study personnel from the subject’s previously 
supplied non-back-up study drug blister cards, if available, except for Visit 6, when no 
study drug will be administered, as the last dose will be taken the day prior to the visit. If 
no tablets from the previously supplied non-back-up blister cards are available, then the 
subject should dose from the new non-back-up blister card supplied at that visit. 
Following completion of accountability and compliance assessments, the back-up blister 
card will be re-dispensed at Visits 3 through 5 and will be collected at Visit 6 along with 
all non-back-up blister cards. The back-up blister card should only be utilized by subjects 
if all study drug from the regularly-supplied (i.e., non-back-up) blister cards has been 
used. If the subject inadvertently took study drug on the day of the study visit, prior to the 
visit, he/she may complete the visit and the actual date and time of the last dose prior to 
the PK blood samples collection will be accurately recorded. 
The exact date and time of last dose prior to the PK sample collection at each visit should 
be documented.  
Study drug will not be administered and all drug will be collected from the subjects at 
Visit 6.  
If a subject discontinues the study prematurely after receiving at least one dose of study 
drug, an Early Termination Visit should be completed at which all procedures listed for 
the EOT visit (Visit 6) should be performed, if possible, prior to initiation of any change 
in the anti-RA medication regimen of the subject. 
3.5.3. Follow-up Period 
Day 84 ±2 (Visit 6/Week 12) to Day 112 ±2 (Visit 7/Week 16)  
The Follow-up Visit will occur approximately four weeks after the last dose of study drug. 
Similar to all other study visits, subjects should arrive under fasted conditions 
(i.e., overnight fast, at least 10 hours prior to blood and urine sample collection). Please 
refer to Table 1 for the list of follow-up procedures to be performed in the study.  
For subjects who discontinue the study prematurely after receiving at least one dose of 
study drug, follow-up procedures, as described for Visit 7 should be performed 
approximately four weeks after the last dose of study drug.

3.5.6.1. 
Efficacy Assessments 
3.5.6.1.1. 
Quantitative Joint Assessments (68/66) 
Standardized 68 and 66 joint counts will be performed for assessment of the number of 
tender and swollen joints, respectively, according to the schedule summarized in Table 1. 
See Figure 3 for a diagram of joints to be assessed as part of the 68/66 tender and swollen 
joint counts. Every effort should be made to ensure that the quantitative joint assessments 
is performed by an experienced, trained independent assessor, different from the Principal 
Investigator/Sub-investigator who is performing overall evaluation of the subject. The 
independent assessor must have medical training (e.g., he/she may be a medical doctor, 
physician assistant, nurse practitioner or registered nurse), must have performed RA joint 
assessments for clinical studies prior to the current study and must have undergone the 
joint count training provided by Akros or designee, as applicable. The same assessor 
should perform the counting for a specific subject throughout the study (scheduling of 
study subjects should take into account the assessor’s availability). In exceptional 
circumstances, if conditions do not permit the availability of the same assessor, an 
alternate assessor may perform the quantitative joint assessment provided that he/she 
meets that experience/training requirements as described above. These exceptions should 
be documented and communicated to the medical monitor. Additionally, every effort will 
be made to limit the number of assessors within a site (ideally, the same assessor will 
perform the quantitative joint assessments for all subjects at a site). See Section 3.5.4.2 
for the restrictions pertaining to the joints to be included in these assessments.

3.6.6.1.1.1 
 Tender/Painful Joint Counts (68) 
Sixty-eight (68) joints will be assessed to determine the number of joints that are 
considered tender or painful. Artificial/missing/fused joints or joints that have received 
corticosteroid injection within 6 weeks of the assessment must not be included in the 
assessment.  
The 68 joints to be assessed are: 
• Upper Body: temporomandibular (2), sternoclavicular (2), acromioclavicular (2); 
• Upper Extremity: shoulder(2), elbow (2), wrist (2) (includes radiocarpal, carpal 
and carpometacarpal considered as one unit), metacarpophalangeals (MCP I[2], II[2], 
III[2], IV[2], V[2]), thumb interphalangeal (IP) (2), proximal interphalangeals (PIP 
II[2], III[2], IV[2], V[2]), distal interphalangeals (DIP II[2], III[2], IV[2], V[2]); 
• Lower Extremity: hip(2), knee(2), ankle(2), tarsus (includes subtalar, transverse 
tarsal and tarsometatarsal considered as one unit) (2), metatarsophalangeals (MTP 
I[2], II[2], III[2], IV[2], V[2]), great toe IP (2), proximal and distal interphalangeals 
combined (PIP II[2], III[2], IV[2], V[2]). 
3.6.6.1.1.2 
 Swollen Joint Counts (66) 
The joint assessor will also assess joints for swelling. Artificial/missing/fused joints or 
joints that have received corticosteroid injection within 6 weeks of the assessment must 
not be included in the assessment. 
The sixty-six (66) joints that will be assessed for swelling are the same as those listed 
above for tenderness/pain, except that the right and left hip joints are not included in the 
swollen joint count.  
3.5.6.1.2. 
Quantitative Joint Assessments (28) 
The 28 joints utilized for the calculation of certain efficacy parameters, such as Disease 
Activity Score (DAS)28, Clinical Disease Activity Index (CDAI) and Simplified Disease 
Activity Index (SDAI), see Appendix 5, are a sub-set of the 68/66 joints assessed per the 
instructions in Section 3.5.6.1.1 (see Figure 4); thus, the results of the above-described 
68/66 joint assessments applicable to the 28 joints should be utilized when reporting the 
28-joint assessment results (i.e., no re-assessment of the 28 joints will be done).

3.5.6.1.3. 
Subject’s Assessment of Arthritis Pain 
Subjects will assess the severity of their arthritis pain according to the schedule 
summarized in Table 1 using a numeric rating scale (NRS) with 0 representing “no pain” 
and 10 representing “pain as bad as it can be”. See Appendix 3 for a template in English 
of the NRS for subject pain assessment. Whenever available, the local language-validated 
tool will be utilized. 
3.5.6.1.4. 
Subject’s Global Assessment (SGA) of Disease Activity 
Using a 0 to 10 NRS format, subjects will assess their disease activity according to the 
schedule summarized in Table 1. See Appendix 3 for a template in English of the 
subject’s global assessment of disease activity scale. Whenever available, the local 
language-validated tool will be utilized. 
3.5.6.1.5. 
Physician’s Global Assessment (PGA) of Disease Activity 
The Investigator will assess the subject’s overall arthritis activity according to the 
schedule summarized in Table 1 using a 0 to 10 NRS format. This is an evaluation based 
on the subject’s disease signs, functional capacity and physical examination, and should 
be independent of the SGA of disease activity. See Appendix 3 for a template in English 
of the PGA of disease activity scale. Whenever available, the local language-validated 
tool will be utilized.

3.5.6.1.6. 
Health Assessment Questionnaire Disability Index (HAQ-DI) 
The HAQ-DI assesses the extent of the subject’s functional ability by assessing the degree 
of difficulty a subject has experienced during the past week in eight categories of daily 
living activities: dressing and grooming, arising, eating, walking, hygiene, reach, grip, 
and common daily activities. Each category has at least two sub-category questions. The 
subjects report the amount of difficulty they have in performing some of these activities. 
The HAQ-DI is designed to assess the subject’s usual ability during the past week, not a 
particularly good or bad day. This questionnaire should be completed by the subject prior 
to any procedures being performed at the visit, if possible. The form should then be 
checked by the site staff for completeness. See Appendix 4 for the Stanford University 
School of Medicine, Division of Immunology & Rheumatology Health Assessment 
Questionnaire Worksheet and for instructions on handling the responses by the 
Investigator, as well as the scoring process that will be performed by the Sponsor.

C-reactive Protein 
The blood samples for CRP measurements utilizing the non-high sensitivity method will 
be collected at Visit 2 and Visit 6 and will be analyzed by the central laboratory. 
3.5.6.2. 
Medical History 
A complete medical history will be obtained at the Screening Visit (Visit 1) and will 
include evaluations for past or present conditions. 
 
 
 Stable or improving pre-existing conditions that are 
detected as part of the screening procedures (e.g., ECG, physical examination, 
, vital signs, and laboratory test abnormalities) are considered to 
be medical history. 
3.5.6.3. 
Prior/Concomitant Medications 
Information pertaining to all medication use (including prescription, over-the-counter, 
supplements, vitamins and minerals) will be collected for the period of at least 30 days 
prior to the Screening Visit (Visit 1) and throughout the study. For medications excluded 
for a longer than a 30-day period, as described in Section 3.5.4.1, the timeframe for 
collecting this information will be extended to cover at least the exclusion period. 
With respect to the use of corticosteroids, detailed information (including but not limited 
to dose, route, indication, duration of administration) will be obtained. Every effort 
should be made to document this information from the time of first use by the subject, 
with focus on chronic use of these agents (i.e., having a duration of ≥ 2 weeks);

Tuberculosis Screening 
The Mantoux skin test (also known as the PPD test) or the Quantiferon®-TB 
Gold-In-Tube test (according to the local SOC) may be used as tuberculosis screening 
tools for the study during the Screening Period.  
If the Mantoux test is selected, the reaction must be read between 48 and 72 hours after 
administration (a subject that does not return after 72 hours must be rescheduled for a 
repeat Mantoux test). The reaction will be measured in millimeters of the induration 
(palpable, raised, hardened area or swelling). The reader will not measure erythema 
(redness). The diameter of the indurated area will be measured across the forearm 
(perpendicular to the long axis). An induration of 5 or more millimeters is considered 
positive. 
If the Quantiferon®-TB Gold-In-Tube test is performed, blood samples will be collected, 
processed and shipped during the Screening Period, according to the laboratory 
instructions. In the case of an indeterminate Quantiferon®-TB Gold-In-Tube test, the test 
may be repeated up to one time if results can be obtained in time prior to Visit 2. If the 
retest is also indeterminate, the PPD test may be performed and, if negative, the subject 
may be randomized into the study, however re-training of the applicable parties at the site 
and/or central laboratory level should be considered. 
Subjects who have had household contact with a person with active tuberculosis are 
excluded, unless appropriate/documented prophylaxis for tuberculosis was administered.

Adverse Events 
3.6.1. Safety Definitions 
Akros complies with the following International Conference on Harmonisation (ICH) AE 
definitions: 
Adverse Event: An AE is any untoward medical occurrence in a patient or clinical 
investigation subject administered a pharmaceutical product and which does not 
necessarily have a causal relationship with this treatment. An AE can therefore be any 
unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or 
disease temporally associated with the use of a medical (investigational) product, whether 
or not related to the medical (investigational) product.  
Serious Adverse Event: As provided by the ICH criteria, an SAE is any adverse drug 
experience occurring at any dose that results in any of the following outcomes: 
• death 
• a life-threatening adverse drug experience 
• inpatient hospitalization or prolongation of existing hospitalization 
• a persistent or significant disability/incapacity 
• a congenital anomaly/birth defect 
• other important medical event 
Note: Important medical events that may not result in death, be life-threatening, or 
require hospitalization may be considered a serious adverse drug experience when, based 
upon appropriate medical judgment, they may jeopardize the patient or subject or may 
require medical or surgical intervention to prevent one of the outcomes listed in this 
definition. Examples of such medical events include allergic bronchospasm requiring 
intensive treatment in an emergency room or at home, blood dyscrasias or convulsions 
that do not result in hospitalization, or the development of drug dependency or drug 
abuse.  
Adverse Reaction: All noxious and unintended responses to an investigational medicinal 
product (IMP) related to any dose administered. 
Note: The phrase "responses to a medicinal product" means that a causal relationship 
between the medicinal product and an adverse event is at least a reasonable possibility, 
i.e., the relationship cannot be ruled out. 
Unexpected Adverse Drug Reaction: An adverse reaction, the nature (specificity) or 
severity of which is not consistent with the applicable product information 
(e.g., Investigator's Brochure). 
Death: Death represents an outcome and a SAE criterion, not an event term. The medical 
condition with the fatal outcome should be reported unless the cause of death is unknown, 
in which case the term “Death” is acceptable.

JTE-051 
AKROS PHARMA INC. 
Clinical Study Protocol AE051-G-13-003 
Inpatient Hospitalization/Prolongation of Hospitalization: Any admission (even if 
less than 24 hours) to a healthcare facility. Admission also includes transfer within the 
hospital to an acute/intensive care unit (e.g., medical floor to the coronary care unit). 
Initial and prolonged hospitalizations that do not meet this SAE criterion include those 
due to social and/or convenience reasons (e.g., lack of personal care at home, unable to 
transfer to non-acute facility), admission to rehabilitation/hospice/skilled nursing 
facilities, emergency room visits, same-day/outpatient/ambulatory procedures, and those 
for pre-planned, elective procedures for a pre-existing condition that did not worsen after 
the informed consent has been signed (no AE present). However, if the hospitalization 
was prolonged due to a complication of a pre-existing condition, the complication 
(diagnosis of same) would qualify as an SAE. 
Disability: A substantial disruption of a person’s ability to conduct normal life functions. 
Life-threatening: Any adverse drug experience that places the patient or subject, in the 
view of the Investigator, at immediate risk of death from the reaction as it occurred, i.e., it 
does not include a reaction that had it occurred in a more severe form, might have caused 
death. 
Physical Examination, 
 Vital Signs, Laboratory Test and 
ECG Abnormalities: Any abnormalities fulfilling the criteria for an SAE should be 
reported as such, in addition to being recorded as an AE in the CRF. Any abnormal vital 
sign, physical 
 finding or laboratory/ECG result which is 
clinically significant (i.e., meets one or more of the following conditions) should be 
recorded as a single diagnosis on the AE page in the CRF: 
• Accompanied by clinical symptoms 
• Leads to permanent discontinuation of study drug 
• Requires a change in concomitant therapy (e.g., addition of, interruption of, 
discontinuation of, or any other change in a concomitant medication, therapy or 
treatment). 
This does not apply to abnormal vital signs, physical finding or laboratory/ECG results 
that do not meet the clinical significance criteria or those which are a result of an AE 
which has already been reported. 
Pre-existing conditions that are detected at the Screening Visit (Visit 1), including 
abnormalities in ECG, physical examination, n
 vital signs, and 
laboratory tests, are considered to be medical history. 
3.6.2. Assessing Adverse Events 
When completing appropriate forms for reporting the AE, the Investigator will be asked 
to assess the AE as follows: 
Seriousness of Adverse Event: 
• Serious: The AE meets a criterion of the SAE definition. 
• Not Serious: The AE does not meet a criterion of the SAE definition.

Severity of Adverse Event:  
• Mild: No interference with functioning. 
• Moderate: No significant interference with functioning. 
• Severe: Significant interference with functioning. 
Relationship of Adverse Event (Causality):  
The Investigator’s causality assessment is the determination whether there is a reasonable 
possibility that the IMP caused or contributed to the adverse event. Generally, the facts 
(evidence) or arguments to suggest causal relationship should be documented. Factors to 
be taken into consideration when assessing causality include: subject’s underlying and 
pre-existing conditions, prior/concomitant medications, timing of onset relative to study 
drug administration, the known PK characteristics of JTE-051, the currently-known safety 
profile 
of 
JTE-051,

drugs, 
the 
de-challenge/re-challenge response (if available) and any other information that is 
considered relevant by the Investigator. 
Akros Pharma Inc. evaluates the relationship of an AE to the study drug using the 
following three categories: 
• Not Related  
• Possibly Related 
• Related 
Action Taken with Regard to Study Drug: 
Akros Pharma Inc. evaluates the action taken with the treatment product and/or 
interacting product using the following four definitions: 
• Dose Not Changed: The subject was on treatment with the study drug when the 
AE occurred, and the study drug dosing was maintained at the same dose level 
• Drug Interrupted: The subject was on treatment with the study drug when the 
AE occurred, and the study drug dosing was temporarily discontinued and then 
re-started 
• Drug Withdrawn: The subject was on treatment with the study drug when the 
AE occurred, and the study drug dosing was permanently discontinued  
• Not Applicable: The subject was not receiving treatment with the study drug 
when the AE occurred (i.e., AE occurred before the first study drug 
administration or after the last study drug administration) 
Other Action Taken:  
• None 
• Additional Treatment Given for the AE 
• Therapeutic/ Diagnostic Procedure 
• Other (including discontinuation/reduction of a concomitant medication due to 
the AE)

Outcome to Date: 
• Not Recovered/Not Resolved: The subject has not yet recovered from the AE; 
the event has not improved (follow-up of all serious AEs will be continued 
until the overall clinical outcome has been ascertained). 
• Recovering/Resolving: The subject has not yet recovered from the AE, 
however, the event is improving (follow-up of all serious AEs will be 
continued until the overall clinical outcome has been ascertained).  
• Recovered/Resolved: The subject recovered from the AE with no sequelae. 
• Recovered/Resolved with Sequelae: The subject recovered from the AE with 
sequelae. 
• Fatal: The subject’s death was a result of the AE.  
3.6.3. Reporting Adverse Events  
Adverse Events Reporting  
Adverse events occurring (initial occurrence or a worsening of a pre-existing condition) 
after the informed consent has been signed and up to 4 weeks (28 days) after the last dose 
of study drug will be reported and included in the study database. However, pre-existing 
conditions detected as part of the screening procedures should be documented as medical 
history. Adverse events will be reported on the AE CRF page.  
Serious Adverse Event Reporting 
Reporting by Investigators 
Detailed instruction regarding SAE reporting will be provided in the appropriate 
documents outside of this protocol. A brief, non-all-inclusive summary is provided below. 
Any SAE experienced by a study subject after signing the informed consent to 28 days 
after the last dose of study drug will be reported to the Sponsor or designee. Additionally, 
SAEs that occur after this period will also be reported to the Sponsor or designee if the 
Investigator considers the SAE related to the study drug. 
Serious adverse events (both initial reports and follow-up information) must be reported 
to the Sponsor or designee within 24 hours of the Investigator’s (site’s) awareness or 
notification of the event. 
The Investigators should make every effort to provide complete information when 
reporting the SAE (both for initial reports, as well as for follow-ups).  
The Investigator must continue to follow the subject until the SAE has subsided, the 
condition becomes chronic in nature, stabilizes (in the case of persistent impairment), or 
the subject dies. Within 24 hours of receipt of follow-up information, the Investigator 
must submit it to the Sponsor or designee. 
The Investigator is also required to submit SAE reports to the IRB/IEC in accordance 
with local requirements. All investigators involved in studies using the same IMP will

AKROS PHARMA INC. 
Clinical Study Protocol AE051-G-13-003 
receive any Suspected Unexpected Serious Adverse Reaction (SUSAR) reports for 
onward submission to their local IRB/IEC as required. All reports sent to investigators 
will be blinded. 
Reporting by the Sponsor 
Competent authorities and IRBs/IECs will be informed by the Sponsor or designee of 
SUSARs according to the local requirements. Additionally, all SUSARs will be reported 
by the Sponsor or designee into the EudraVigilance system, as appropriate. Cases will be 
unblinded by designated personnel for reporting purposes as required. 
Exposure in Utero Reporting: 
If a female subject becomes pregnant or the female partner of a male subject participating 
in the study becomes pregnant after the subject receives the first dose of study drug, or 
within 28 days of discontinuing study drug, the Investigator should report the pregnancy 
to the Sponsor or designee within 24 hours of being notified.  
The subject/partner should be followed by the Investigator until completion of the 
pregnancy. If the pregnancy ends for any reason before the anticipated date, the 
Investigator should notify the Sponsor or designee. At the completion of the pregnancy, 
the Investigator will document the outcome of the pregnancy. If the outcome of the 
pregnancy meets the criteria for immediate classification as an SAE (i.e., spontaneous 
abortion, stillbirth, neonatal death, or congenital anomaly), the Investigator should follow 
the procedures for reporting an SAE as described above. 
Overdose Reporting: 
An overdose is a significant variation from the recommended/scheduled dosage for a 
product. For the purposes of this study, overdose is defined by any confirmed use of 
blinded study medication of more than four tablets once a day. If such situations occur, 
the Investigator should provide additional training to the subject on study drug dosing 
instructions and emphasize the importance of compliance. Currently there is no known 
antidote to JTE-051, thus appropriate symptomatic and/or supportive care is to be 
provided at the Investigator’s discretion, as needed. The subject’s continued eligibility 
will be left to the judgment of the Investigator. 
Information on overdoses in subjects is collected by the Sponsor or designee. Should a 
subject experience an overdose during the course of the study, the investigator or 
qualified designee must report the overdose as soon as possible, but not later than the 
timeframe requested by the Sponsor or designee after the investigator or qualified 
designee first becomes aware of the overdose. Instructions will be provided on how to 
collect this information.

Identification of Treatments  
3.7.1. Method of Assigning Subjects to Treatment Groups 
At the Screening Visit (Visit 1), each site will assign potential study subjects an 
eight-character subject number. This number will consist of a four-digit site number (with 
the first two digits representing the country-specific number and the next two digits 
representing the site-specific number) and a three-digit subject number assigned in a 
sequential manner. The hyphen between the site and subject number will account for the 
eighth character. This number will represent the subject’s identifier throughout the study. 
Following confirmation of eligibility at Visit 2, the Interactive Web Response System 
(IWRS) will be contacted by the site and it will assign the subject a four-digit 
randomization number that will correspond to a randomly assigned treatment group. 
3.7.2. Identity of Investigational Products  
 
3.7.3. Storage and Handling Procedures 
The JTE-051 and placebo tablets should be stored at room temperature between 20 and 
25°C (United States Pharmacopeia [USP]) and in a secure location with restricted access.  
3.7.4. Clinical Supplies Packaging 
Each site will receive a supply of double-blind study drug packaged as blister cards 
corresponding to 8 days of QD dosing. Each blister card will contain a total of 
32 JTE-051 tablets.  
Study drug blister cards may be labeled with the following information, as appropriate: 
• Sponsor identity and protocol number 
• Card number 
• Dosing instructions 
• Spaces for site personnel to add subject number and subject initials

3.7.5. Administration of Study Drug 
During the Treatment Period, beginning on the day of Visit 2, subjects will 
self-administer one dose of study drug (4 tablets) daily for 12 weeks. Study drug will be 
taken once daily in the morning, regardless of meals. On the day of scheduled study visits, 
subjects should not take study drug prior to arriving to the study site. At the site, study 
drug will be administered from the previously supplied non-back-up blister card, if 
available, after all study procedures have been completed. If no tablets from the 
previously supplied non-back-up blister cards are available, then the subject should dose 
from the new non-back-up blister card supplied at that visit. The back-up study drug 
blister card should only be utilized by subjects if all study drug from the 
regularly-supplied (non-back-up) blister cards has been used. 
Randomized subjects will receive two study drug blister cards at Visits 2 and 3, 
respectively. Subjects will receive four blister cards each on Visits 4 and 5. Additionally, 
at Visit 2, all subjects will receive a back-up blister card (identical in appearance with the 
other blister cards) for use as needed throughout the study. The back-up blister card may 
be identified at the site level and subjects will be instructed to utilize all tablets from the 
other (non-back-up) blister cards before initiating tablet use from the back-up blister card. 
The subjects will be instructed to return the clinical supplies (full, partially full, and 
empty blister cards, including the back-up blister card) at Visits 3, 4, 5 and 6 for 
accountability and compliance assessment. Following completion of accountability and 
compliance assessments, the back-up blister card will be re-dispensed at Visits 3 through 
5 and will be collected at Visit 6 along with all non-back-up blister cards.

In the event that the subject does not take the study drug on a given day during the 
Treatment Period, the subject should not take more than the daily dosage on the following 
treatment day. 
3.7.6. Management of Clinical Supplies 
The Investigator will have responsibility for the control and proper distribution of all 
study drug (including any investigational product or reference product) in accordance 
with this protocol. The Investigator is responsible for ensuring that all study drug will be 
stored at the site at recommended storage temperatures and conditions, in a secured area, 
free of environmental extremes, with restricted access. The Investigator also ensures that 
all study drug will be dispensed only to study subjects who have provided written 
informed consent and have met all entry criteria. 
Study drug accountability will be performed by the Investigator or designee at each study 
visit during the Treatment Period, according to the schedule of procedures presented in 
Table 1. Study drug compliance will be assessed and documented per GCP. 
3.7.7. Randomization 
Approximately 250 eligible subjects with active RA will be randomized into this study. 
Subjects will be randomized in a 1:1:1:1:1 ratio (50 subjects per treatment group) to 
receive JTE-051 50 mg, JTE-051 100 mg, JTE-051 150 mg, JTE-051 200 mg or placebo 
once daily. Randomization will be stratified by region and by the screening hs-CRP level 
(the qualifying hs-CRP value must be utilized). 
An IWRS will be employed for the randomization activities. It will use a stratified 
randomization algorithm that takes into account the strata specified above. 
The randomization code will be controlled by an unblinded member of the Sponsor or 
designee who will provide the randomization code to select laboratories, see 
Section 3.7.8.  
3.7.8. Blinding  
This study is double-blind (i.e., the treatment assigned to each subject will not be 
disclosed to the Sponsor members or designees involved in the study, study staff at the 
site or to the subject). The JTE-051 50 mg tablets, as well as the placebo tablets will be 
supplied as unbranded tablets which are identical in appearance.  
The laboratory performing the JTE-051 plasma concentration assessments will be 
unblinded to facilitate analysis of only the samples from the JTE-051-treated subjects. 
Plasma samples from placebo-treated subjects may be analyzed as needed (see 
Section 3.5.6.24). 
3.7.9. Breaking the Blind 
The study drug code may be broken by the Investigator for a particular subject only in the 
event of a serious adverse experience, which the Investigator feels cannot be adequately

treated without knowing the identity of the study drug by using the IWRS. Every effort 
must be made to contact the Sponsor’s Medical Monitor prior to breaking the code. If this 
is not possible and the situation is an emergency, the Investigator may break the blind to 
identify the treatment assignment for the specific subject only and must contact the 
Sponsor’s Medical Monitor as soon as possible thereafter. The Sponsor may also elect to 
break the blind for cause. If the blind is broken, appropriate documentation should be 
completed as soon as possible. 
Additionally, breaking of the blind may be performed by designated members of 
pharmacovigilance group not involved in the clinical conduct of the study for regulatory 
reporting purposes, as appropriate.  
3.8. 
Statistical Methods 
This section provides an abbreviated statistical analysis plan (SAP) for the efficacy and 
safety parameters. A formal SAP will be developed at a later time. Statistical issues not 
addressed in the present section may be developed in the formal SAP. The plans outlined 
in this section may be modified in the SAP; however, any major modifications of the 
primary endpoint definition and/or its analysis may also be reflected in a protocol 
amendment, as appropriate. Other deviations to the SAP will be discussed in the study 
report. 
3.8.1. Subject Population for Analysis 
3.8.1.1. 
Randomized Population 
The randomized population consists of all subjects who are randomized at Visit 2 to one 
of the five treatment groups: JTE-051 50 mg QD, 100 mg QD, 150 mg QD, 200 mg QD 
and matching placebo QD. 
3.8.1.2. 
Safety Population 
Safety population consists of the randomized subjects who receive at least one dose of the 
study drug (the actual received drug will be considered).   
3.8.1.3. 
Intent-To-Treat (ITT) Population 
The ITT population consists of the randomized subjects who receive at least one dose of 
the study drug per randomization. 
3.8.1.4. 
Per Protocol (PP) Population 
The PP population is a subset of the ITT population in which subjects do not have any 
major protocol deviations. A pre-analysis meeting will take place after all data have been 
entered into the database and cleaned, but before the release of the randomization code, to 
identify the PP population. The decisions made to select the PP population will be 
documented.

The PK population consists of the randomized subjects who receive at least one dose of 
JTE-051 and have at least one usable JTE-051 plasma concentration measurement. 
3.8.1.6. 
Sample Size 
Approximately 250 eligible subjects (50 in each treatment group) will be randomized into 
the DB treatment period of this study.   
The primary efficacy evaluation will be to compare the ACR20 response rate between 
JTE-051 with placebo at EOT. From one study comparing marvilimumab with placebo in 
combination with stable methrotrexate26, the ACR20 of marvilimumab and placebo at 
Week 12 were 0.69 and 0.40, respectively. Assuming the ACR20 of at least one of the 
JTE-051 doses to be at least 0.30 above placebo, the following sample size per group will 
be needed to detect a statistical significant difference at the 5% level with about 80% 
power (using 2-sided Fisher’s exact test): 
 
 
 
 
About 50 randomized subjects per group would therefore give at least an 80% power for a 
range of placebo responses. The sample size calculation was carried out using the 
software SiZ 6.2 (Cytel Inc., 2013). 
3.8.2. Interim Analysis 
No interim analysis is planned for the study. 
3.8.3. Efficacy Analyses 
The ITT population will be used for all efficacy data analysis. The analysis of the primary 
efficacy parameter will be repeated on the PP population if it excludes 20% or more of 
the subjects from the ITT population. Additional efficacy parameter analyses using the PP 
population and/or other sub-population may be performed if deemed appropriate.  
3.8.3.1. 
Efficacy Parameters 
The primary efficacy parameter is the ACR20 response rate at EOT. 
The secondary efficacy parameters are (evaluated at Weeks 2, 4, 8, 12 and 16 
respectively, unless otherwise stated): 
• Percentage of subjects achieving ACR20/50/70 response rate  
• Change from baseline in SDAI 
• Percentage of subjects who achieved remission based on SDAI (≤3.3) 
• Percentage of subjects who achieved low disease activity based on SDAI (≤11)  
• Change from baseline in CDAI 
• Percentage of subjects who achieved remission based on CDAI (≤2.8)

3.8.3.2. 
Efficacy Data Analysis 
For the purpose of efficacy analysis, the EOT value is defined as the last value taken 
during the DB treatment period after the first dose of study drug without any treatment 
intervention. For subjects who receive rescue treatment, the last value prior to the 
intervention will be defined as the EOT. 
For the primary efficacy parameter (ACR20 at EOT), the Fisher’s exact test will be used 
to compare each JTE-051 dose group with placebo. Furthermore, the exact 
Cochran-Armitage trend test27 will be computed, using the ordinal score for treatment, 
e.g., score 1 for placebo, score 2 for the lowest JTE-051 dose, etc. 
For dichotomous secondary efficacy parameters, similar analyses as the primary efficacy 
parameter will be used by time point, i.e., the Fisher’s exact test for pairwise comparisons 
with placebo and the Cochran-Armitage test for trend.

Clinical Study Protocol AE051-G-13-003 
For continuous efficacy parameter analysis with multiple time points, a mixed effect 
model will be employed. It includes fixed effects for treatment, time, treatment by time 
interaction, the stratification factors and the appropriate baseline, and subject as the 
random effect. The appropriate baseline will be the parameter from which the efficacy 
parameter is derived, e.g., SDAI at Week 0 for the analysis of change from baseline in 
SDAI. The treatment effect of each JTE-051 dose group relative to placebo at the same 
time point will be estimated. A linear trend test at each time point will be computed using 
appropriate linear contrast. 
All analyses will be performed two-sided at the 5% significance level. No formal multiple 
comparison adjustment will be made, therefore results should be interpreted with the 
multiplicity in mind. The estimated treatment effect (relative to placebo) from the model, 
along with a two-sided 95% CI and p-value, will be tabulated where appropriate. The 
Newcombe’s CI of the rate difference28 between JTE-051 dose and placebo will be 
computed when performing the Fisher’s exact test. Graphical presentations of the 
treatment profile may be depicted. Sensitivity analysis, model fit assessment may be 
conducted and data transformation may be employed if appropriate. 
Descriptive statistics of efficacy parameters over time will be presented by treatment. 
They will include the number of subjects (N), arithmetic mean, standard deviation (SD), 
median, minimum and maximum for continuous parameters, and in frequency tabulation 
form for dichotomous parameters.

Treatment by Center Effect 
The randomization of this study is stratified by region and by the screening hs-CRP level. 
Center effect is not considered due to the expectation that many centers will be used and 
only a small number of subjects will be enrolled in most centers. The region effect will be 
included in the analysis model where appropriate. 
3.8.3.4. 
Treatment by Baseline Covariate Effect 
The treatment-by-baseline effect is not considered, however the baseline will be included 
in the respective parametric analysis model of the efficacy parameters where appropriate.  
3.8.3.5. 
Subgroup Analysis 
Subgroup analyses may be performed if appropriate. 
3.8.3.6. 
Handling of Dropouts or Missing Data 
Some efficacy parameters are a composite value derived from a complex instrument. The 
chance that one of its components is missing increases greatly due to various reasons. In 
order to minimize missing data, algorithms will be prepared to compute the derived value 
where reasonable in case some of the components are missing. These algorithms will be 
described in the SAP. 
There will be missing data however, either intermittent like a missing visit or due to 
subject dropout. For dichotomous efficacy parameters analysis by time point, subjects 
with missing data will not be included in the analysis. For analysis with multiple time 
points, any missing data will be imputed using the last observation carried forward 
(LOCF) method except for subjects who withdraw for reasons related to treatment. In the 
latter case, any value after withdrawal will be imputed as treatment failure. For 
parameters analyzed both by time point and with multiple time points, these two 
approaches would strengthen the findings when they are similar. 
For continuous efficacy parameters, no imputation will be employed. This is because the 
mixed effect model gives valid estimates if the missing data mechanism is “missing at 
random”, a common assumption made as the first approach for analysis.

parameters, change from baseline will be summarized by treatment as appropriate. 
Potentially clinically significant values for vital signs, ECG, and laboratory data will be 
flagged in data listings and may be summarized as appropriate. 
All safety data will be presented in the data listings, and will be flagged for events of 
interest (e.g., out of range laboratory data) as appropriate. 
Adverse events will be coded using the Medical Dictionary for Regulatory Activities

of JTE-051. Population estimates of PK parameters of JTE-051 such as the apparent oral 
clearance of drug following extravascular administration (CL_F) and apparent volume of 
distribution following extravascular administration (V_F) will be estimated, and intra- 
and inter-subject variability of these parameters will be characterized. The effect of

Handling Responses (by the Investigator) 
For each question in the questionnaire, the level of difficulty is scored from 0 to 3 with 0 
for “Without ANY difficulty,” 1 for “With SOME difficulty,” 2 for “With MUCH 
difficulty,” and 3 for “UNABLE to do”. 
• The HAQ-DI questionnaire should be completed by the study subject, following 
receipt of detailed instructions from the Investigator/study staff. After the subject 
completes the questionnaire and prior to the subject leaving the study site, the study 
staff should perform a detailed review of the answers, discuss why any questions 
were not answered, and what was intended when answers were marked outside the 
box or more than one box was marked for a question. 
• Each subject should answer the questions according to his/her personal situation. 
Thus, the ratings, “Without ANY difficulty”, “With SOME difficulty”, “With 
MUCH difficulty”, and “UNABLE to do”, are deliberately not defined for subjects. 
For example, if a subject asks what “SOME” means, an appropriate response would 
be “Whatever you think ‘SOME’ means to you”. 
• When a sub-category item does not apply, e.g., when a subject does not use shampoo 
(or perhaps has no hair), the subject should give the response that represents the 
ability the subject believes he/she would have had in attempting the activity. 
• When a subject uses aids or devices (e.g., crutches, jar openers), the subject should 
answer the question based on the usual equipment or way of performing the activity. 
If the subject has no difficulty doing an activity when using aids/devices, the subject 
should mark the “Without ANY difficulty” option. In scoring, the use of aids/devices 
results in an adjusted score for that item. 
• Notes about Aids/Devices: The assignment of devices to particular disability 
categories assumes that the devices are used only for their intended purposes as 
shown in Table 2 below. For example, when a subject indicates use of a cane, it is 
presumed that the cane is used as an aid in walking. 
  If the subject informs the Investigator/site personnel that a device listed is being 
used for a different activity other than those shown in Table 2, (e.g., a cane is 
used for getting up from bed but not walking), or if a different device, not listed 
on the HAQ-DI form is utilized by the subject, then the Investigator must 
confirm for which activity category the specific device is utilized and a device 
from the list that is specific for that same activity category should be checked. 
This may be a different device than the one actually used (e.g., “built up or 
special chair” should be checked instead of “cane” in this example). 
  If a device is used for any activity in the “ACTIVITIES” category, as listed on 
Page 4 of the HAQ-DI questionnaire, only the “Errands and chores” under 
“HELP FROM ANOTHER PERSON” should be checked (i.e., none of the AIDS 
and DEVICES listed on Page 4 should be checked). This will ensure the 
appropriate adjustment to the score for the "ACTIVITY" category (this is done 
programmatically).

• Items left blank or multiple answers: If all component questions are blank or if 
more than one answer is given, then follow-up with the subject at the time of the 
visit is required. 
• Improperly Marked Items: If the subject’s mark is outside the answer box, then 
move it to the closest one. If it’s directly between the two, move it to the answer with 
greater difficulty. However, follow-up with the subject and confirmation of intended 
answer should be done at the time of the visit, and all items should be marked 
appropriately before the subject leaves the study center. 
NOTE: A HAQ-DI score cannot be calculated validly when there are scores for 
less than six of the eight categories. 
Scoring (performed by the Sponsor) 
The HAQ-DI’s scoring conventions allow for the computation of two disability indices: 
1. The Standard HAQ-DI is the preferred and traditional scoring method which takes into 
account the use of aids/devices. 
2. The Alternative Disability Index does not take into account the use of aids/devices. 
A subject must have a score for at least six of the eight categories. Otherwise a HAQ-DI 
score cannot be validly computed. For the purpose of the current study, the standard 
computing method will be applied. 
Computing the Standard HAQ-DI Score (With Aids/Devices): There are three steps: 
1. Sum the 8 category scores by using the highest sub-category score from each 
category (for example, in the category “EATING” there are three sub-category 
items. If a subject responds with a 1, 2, and 0, respectively; the category score is 2). 
2. Adjust for use of aids/devices and/or help from another person when indicated. 
Table 2 identifies the Aid/Devices companion variable for each HAQ-DI category.

• Adjust the score for a category by increasing a zero or a one to a two. 
• If a subject's highest score for that sub-category is a two it remains a two, and if a 
three, it remains a three. 
3. Divide the summed category scores by the number of categories answered (must be 
a minimum of 6) to obtain a HAQ-DI score of 0-3 (3=worst functioning).

Appendix 5. Efficacy Endpoints Calculation 
Numeric ACR (ACR-N) Index 
The ACR-N will be derived by the Sponsor for Visits 3 through 7 based on the ACR core 
set measures collected by the Investigator. See Section 3.5.6.1 for the description of the 
ACR core set measures assessments by the Investigator. 
This is a continuous variable expressing the percentage improvement from baseline a 
subject has experienced, defined as the minimum of percent improvement in swollen 
joints, tender joints and the median percent change in the other five ACR core set 
measures: 
1. Subject’s Assessment of Arthritis Pain. 
2. Subject’s Global Assessment of Disease Activity. 
3. Physician’s Global Assessment of Disease Activity.  
4. Health Assessment Questionnaire Disability Index (HAQ-DI) 
5. Acute phase reactant (hs-CRP) 
Thus, and ACR-N of X means that the subject has achieved a change of at least X% in the 
tender and swollen joint counts and a change of at least X% in the median of the other 
five other parameters. ACR-N will take a negative value if a there is a worsening in either 
the swollen joint count, tender joint count and the median of the other five ACR core set 
measures (i.e., a subject can have a negative ACR-N despite improving in two of the 
three components). 
The ACR20/50/70 Response Rate 
The ACR20/50/70 response rate will be calculated by the Sponsor for Visits 3 through 7 
based on the ACR core set measures collected by the Investigator.  
This composite parameter measures improvement in tender (68) and swollen (66) joint 
counts and improvement in at least three of the following five ACR core set measures as 
listed above. 
The ACR20/50/70 response rate is a dichotomous variable with a positive (= responder) 
or negative (= non-responder) outcome.  
 
ACR20 is ≥20% improvement 
 
ACR50 is ≥50% improvement 
 
ACR70 is ≥70% improvement

Disease Activity Score (DAS) 2829 
The DAS assessment is a derived measurement with differential weighting given to each 
component. The DAS 28 (CRP) will be calculated by the Sponsor at all study visits. See 
Section 3.5.6.1.2 for the list of 28 joints included in the DAS calculation. 
The components of the DAS 28 arthritis assessment include: 
1. Tender/Painful Joint Count (28) 
2. Swollen Joint Count (28) 
3. CRP 
4. Subject’s Global Assessment of Disease Activity 
DAS28(CRP) = 0.56 X √(TJC28) + 0.28 X √(SJC28) + 0.36 X Ln(CRP+1) + 0.014 X 
SGA + 0.96 
Percentage of Subject achieving Boolean Remission 
This secondary efficacy parameter will be calculated by the Sponsor, based on the 
following definition: 
• 
Tender joint count (TJC) (28) ≤1 
• 
Swollen joint count (SJC) (28) ≤1 
• 
C-reactive protein ≤1 mg/dL  
• 
Subject’s global assessment (SGA) of disease activity ≤1 (on a 0 - 10 scale) 
EULAR Response Criteria 
The EULAR response criteria will be assessed by the Sponsor. 
This parameter takes into account both the change in DAS28 between two timepoints, as 
well as DAS28 value at a specific timepoint. 
DAS28-CRP will be utilized in calculating the EULAR response in the study subjects.

1. INTRODUCTION 
Final version of the protocol for this phase 2 double-blind (DB), placebo-controlled, parallel-group 
study evaluating efficacy, safety and pharmacokinetic (PK) of JTE-051 in subjects with active 
rheumatoid arthritis (RA) on stable disease-modifying anti-rheumatic drug (DMARD) therapy, 
including methotrexate (MTX) was completed on April 24, 2015. The protocol was amended on 
24 March 2016. The protocol Amendment 1 and the electronic case report form (eCRF) contain 
details on the study conduct and data collection. 
 
This document describes the statistical methods and data presentations to be used in the summary 
tables, listings and figures. 
2. OBJECTIVES 
• To evaluate the efficacy of JTE-051 in subjects with active RA receiving background 
non­biologic DMARD therapy  
• To evaluate the safety and tolerability of JTE-051 administered for 12 weeks to subjects with 
active RA receiving background non-biologic DMARD therapy  
• To evaluate the PK of JTE-051 in plasma of subjects with active RA  
3. STUDY DESIGN 
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group, 12-week study 
in biologic and kinase inhibitor treatment-naive RA subjects on stable background non­biologic 
DMARD therapy, including MTX.  
Eligible subjects are randomized at Visit 2 to receive JTE-051 50 mg, 100 mg, 150 mg, 200 mg or 
placebo once daily for 12 weeks. Subjects continue to receive up to two non­biologic DMARDs, 
including MTX throughout the study (at a stable background dose and route of administration for 
at least 12 weeks prior to Visit 2 and throughout the study) and return for a Follow-up Visit 
approximately four weeks after the last dose of study drug is administered. Subject randomization 
are stratified by geographical region (Europe, the Middle East and Africa [EMEA], Latin America, 
[LA] and the United States [US]) and by the screening high-sensitivity C-reactive protein (hs-CRP) 
(≤2 x ULN, >2 x ULN).  
The study duration will be of approximately 20 weeks per subject:  
• 
Up to a 28-day Screening Period  
Note: Certain pre-defined exceptions that would allow for a longer duration of the screening 
period to ensure a 28-day pre-randomization stabilization of concomitant medications 
arepermitted, as described in Section 3.5.4.1 of the protocol.  
• 
A 12-week double-blind Treatment Period 
• 
Approximately a 4-week Follow-up Period

visit within the specified windows, the visit should be scheduled as closely as possible to these 
windows. A subject should not skip a protocol-specified visit due to scheduling difficulties. 
 
 
c. Unless a chest radiography had been performed within 3 months (12 weeks) of the Screening Visit, 
and documentation is available for review by the Investigator and inclusion in the subject’s file. 
d. At Visit 1 serum pregnancy test will be performed; at all other visits, urine pregnancy tests will be 
performed. Pregnancy tests may also be repeated as needed or per request from institutional review 
boards (IRB)/independent ethics committees (IEC) or if required by local regulations. 
e. Rheumatoid Factor 
f. Anti-cyclic citrullinated peptide antibodies 
g. At Visit 2, a back-up drug blister card will be dispensed to all subjects, in addition to the regular 
study drug blister cards. Subjects will be instructed not to use the back-up blister card unless all 
drug in the regular blister cards has been used and to bring all used and unused (including back­up) 
blister cards to each study visit for accountability purposes. At Visit 6, study drug will not be 
dispensed. If a study subject discontinues study drug prematurely, the appropriate systems will be 
accessed to record termination as soon as possible after the decision has been made. 
h. Study drug compliance will be calculated by the site at each visit during the treatment period 
starting at Visit 3, based on the number of tablets dispensed/returned by the subject. The subject is 
to maintain the back-up blister card for the duration of the treatment period. 
i. 
Oral administration for 12 weeks starting on the day of randomization at Visit 2, QD in the morning, 
regardless of meals. On study visit days, subjects should take their scheduled study treatment from 
their existing study drug supply (if available) at the site, under the supervision of the investigator 
or designee after all study-related procedures have been performed (except for Visit 6, when no 
study drug will be administered, as the last dose will be taken the day prior to the visit). If no tablets 
from the previously supplied non-back-up blister cards are available, then the subject should dose 
from the new blister card supplied at that visit. Following completion of accountability and 
compliance assessments, the back-up blister card will be redisposed at Visits 3 through 5 and will 
be collected at Visit 6 along with all non-back-up drug blister cards. The back--up blister card 
should only be utilized by subjects if all study drug from the regularly supplied (i.e., non-back-up) 
blister cards has been used. 
j. 
Adverse event information will be collected at the specified time points as well as at any time when 
a clinical research unit staff member becomes aware of an AE after the subject signs the informed 
consent for the study. However, stable or improving pre-existing conditions that are detected 
through the screening procedures throughout the Screening Period (e.g., abnormalities in ECG, 
physical examination, 
 vital signs and laboratory tests) are medical 
history and should be documented accordingly.

4. SUBJECT POPULATIONS 
Randomized Population 
The randomized population consists of all subjects who are randomized at Visit 2 to one of the 
five treatment groups: JTE-051 50 mg QD, 100 mg QD, 150 mg QD, 200 mg QD and placebo 
QD. 
Safety Population 
Safety population consists of the randomized subjects who receive at least one dose of JTE-051 
or placebo after the randomization, including those who did not complete the study. 
Intent-To-Treat (ITT) Population  
The Intent-To-Treat (ITT) population consists of the randomized subjects who receive at least 
one dose of the study drug and have at least one post-baseline efficacy assessment during the 
DB treatment period. 
Per Protocol (PP) Population 
The Per Protocol (PP) population is a subset of the ITT population in which subjects do not 
incur any of the major protocol deviations below.  
Major protocol deviation criteria:  
1. Dosing compliance not in 80-120% (based on actual dosing period) 
2. Subject’s last dose not between Days 68-100 
3. Subject did not take 272-400 tablets in total 
4. >4 days between last dose and last non-follow-up efficacy assessment 
5. Not meeting Inclusion Criterion #3 or #4 
6. Not meeting Exclusion Criterion #1, #2 or #28  
7. Subject took “key” prohibited concomitant medications or had unstable background 
therapy that could potentially affect efficacy results/interpretation 
8. Subject took incorrect study medication, e.g. due to incorrect drug dispense  
9. Significant procedural deviations/non-compliance that could potentially affect efficacy 
results/interpretation
A pre-analysis meeting will take place after all data have been entered into the database and 
cleaned, but before the release of the randomization code, to identify the PP population. The 
decisions made to select the PP population will be documented. 
Pharmacokinetic (PK) Population 
The PK population consists of the randomized subjects who receive at least one dose of 
JTE-051 and have at least one usable JTE-051 plasma concentration measurement.

5. ANALYSIS PARAMETERS 
Demographic and Baseline Characteristics 
Demographic variables include age, gender, ethnic group, geographical region, race, body 
weight, height and body mass index (BMI). 
Baseline (last non-missing value prior to first dose) subject characteristics include the 
following parameters: duration (years) of active RA, tender/painful joint counts (68 and 28), 
swollen joint counts (66 and 28), subject’s assessment of arthritis pain, subject’s global 
assessment (SGA) of disease activity, physician’s global assessment of disease activity (PGA), 
Health Assessment Questionnaire Disability Index (HAQ-DI), hs-CRP, Disease Activity Score 
28 with CRP (DAS28-CRP), Simple Disease Activity Index (SDAI), Clinical Disease Activity

5.2.5 Efficacy Endpoints Calculation  
5.2.5.1 Numeric ACR (ACR-N) Index 
The numeric ACR (ACR-N) will be derived by the sponsor for Visits 3 through 7 based on the 
ACR core set measures collected by the Investigator. See Section 3.5.6.1 of the protocol for 
the description of the ACR core set measures assessments by the Investigator. 
This is a continuous variable expressing the percentage improvement from baseline a subject 
has experienced, defined as the minimum of percent improvement in swollen joints, tender 
joints and the median percent change in the other five ACR core set measures: 
1. Subject’s Assessment of Arthritis Pain. 
2. Subject’s Global Assessment of Disease Activity. 
3. Physician’s Global Assessment of Disease Activity.  
4. Health Assessment Questionnaire Disability Index 
5. Acute phase reactant (hs-CRP) 
Thus, an ACR-N of X means that the subject has achieved a change of at least X% in the tender 
and swollen joint counts and a change of at least X% in the median of the other five other 
parameters. Numeric ACR will take a negative value if a there is a worsening in either the 
swollen joint count, tender joint count and the median of the other five ACR core set measures 
(i.e., a subject can have a negative ACR-N despite improving in two of the three components). 
5.2.5.2 The ACR20/50/70 Response Rate 
The ACR20/50/70 response rate will be calculated by the sponsor for Visits 3 through 7 based 
on the ACR core set measures collected by the Investigator.  
This composite parameter measures improvement in tender (68) and swollen (66) joint counts 
and improvement in at least three of the following five ACR core set measures as listed above. 
The ACR20/50/70 response rate is a dichotomous variable with a positive (= responder) or 
negative (= non-responder) outcome.  
ACR20 is ≥20% improvement 
ACR50 is ≥50% improvement 
ACR70 is ≥70% improvement

5.2.5.5 Disease Activity Score (DAS) 28 
The DAS assessment is a derived measurement with differential weighting given to each 
component. The DAS 28 (CRP) will be calculated by the Sponsor at all study visits. See 
Section 3.5.6.1.2 of the Protocol for the list of 28 joints included in the DAS calculation. 
The components of the DAS 28 arthritis assessment include: 
1. Tender/Painful Joint Count (28) 
2. Swollen Joint Count (28) 
3. CRP 
4. Subject’s Global Assessment of Disease Activity 
The DAS 28 will be calculated using the following formula: 
DAS28(CRP) = 0.56 X √(TJC28) + 0.28 X √(SJC28) + 0.36 X Ln(CRP+1) + 0.014 X 
SGA + 0.96 
5.2.5.6 Percentage of Subjects achieving Boolean Remission 
This secondary efficacy parameter will be calculated by the Sponsor, based on the following 
definition: 
• 
Tender joint count (TJC) (28) ≤1 
• 
Swollen joint count (SJC) (28) ≤1 
• 
C-reactive protein ≤1 mg/dL 
• 
Subject’s global assessment (SGA) of disease activity ≤1 (on a 0 - 10 scale) 
5.2.5.7 EULAR Response Criteria 
The EULAR response criteria will be assessed by the Sponsor. 
This parameter considers both the change in DAS28 between two time points, as well as 
DAS28 value at a specific time point. 
DAS28-CRP will be utilized in calculating the EULAR response in the study subjects.

5.2.5.8 HAQ-DI Score and Calculation 
The HAQ-DI’s scoring conventions allow for the computation of two disability indices: 
1. The Standard HAQ-DI is the preferred and traditional scoring method, which considers the
use of aids/devices.
2. The Alternative Disability Index does not consider the use of aids/devices.
A subject must have a score for at least six of the eight categories. Otherwise a HAQ-DI score 
cannot be validly computed. For this study, the standard computing method will be applied. 
Computing the Standard HAQ-DI Score (With Aids/Devices): There are three steps: 
1. Sum the 8 category scores by using the highest sub-category score from each category (for 
example, in the category “EATING” there are three sub-category items. If a subject 
responds with a 1, 2 and 0, respectively; the category score is 2).
2. Adjust for use of aids/devices and/or help from another person when indicated. Table 2 
identifies the Aid/Devices companion variable for each HAQ-DI category.
Table 2. 
Companion Aids/Device Items for HAQ-DI Categories

Cane walker, crutches, wheelchair 
Hygiene 
Raised toilet seat, bathtub seat, bathtub bar 
Long handled appliances in bathroom 
Reach 
Long handled appliances for reach 
Grip 
Jar opener (for jars previously opened) 
•
Adjust the score for a category by increasing a zero or a one to a two.
•
If a subject's highest score for that sub-category is a two it remains a two, and if a three,
it remains a three.
3. Divide the summed category scores by the number of categories answered (must be a
minimum of 6) to obtain a HAQ-DI score of 0-3 (3=worst functioning)
4. If any component in HAQ-DI derivation is missing and HAQ-DI cannot be derived, no
imputation will be done, and HAQ-DI will be left as missing.

Safety Parameters 
Adverse Events (AEs)
The Medical Dictionary for Regulatory Activities (MedDRA) Version 21.0 will be used to 
map verbatim AEs to preferred terms and their respective primary system organ classes. 
However, a different (non-primary) system organ class may be selected where appropriate after 
a medical review of the mapping. Adverse events will be characterized as either pre-treatment 
or treatment-emergent according to the criteria described in the following sections. 
 Pre-treatment Adverse Events 
A pre-treatment AE is one with an onset date prior to the date of the first dose of study drug. 
For an AE occurring on the day of first dose, all AEs occurring on the day of first dose will 
be considered as TEAE when the time of AE occurrence relative to the dosing is unknown. 
5.3.3 Treatment-Emergent Adverse Events
A treatment-emergent AE is defined as any AE with an onset date on or after the first dose of 
study drug, provided that this AE did not previously occur during the pre-treatment period (i.e., 
before the first dose of study drug taken after randomization). However, a pre-treatment AE 
can become treatment-emergent if it continued from the pre-treatment period but worsened 
after the first dose of study drug or it stopped and re-occurred (a new onset time) with a worsen 
severity after the first dose of study drug. 
5.3.4 Medical History 
A complete medical history will be obtained at the Screening Visit (Visit 1) and will include 
evaluations for past or present conditions. 
 
t
 
. Stable or improving pre-existing conditions that are detected as part of the 
screening procedures (e.g., ECG, physical examination, n
 vital signs 
and laboratory test abnormalities) are medical history. 
5.3.5 Study Medication Compliance 
Total number of tablets taken will be recorded in the eCRF for the corresponding intervals 
as scheduled in Table 1. Compliance of the study medication will be calculated as follows: 
Compliance (%) = 
Total tablets taken
Treatment duration × 4 x 100% 
Compliance will be calculated for both the treatment duration between visits and the entire 
treatment period. 
5.3.6 Clinical Laboratory Results 
Hematology, coagulation, serum biochemistry, bone-specific alkaline phosphatase, lipid 
profile and urinalysis are collected as scheduled in Table 1. The following information will be

parameters: 
• Change from baseline at all post-baseline visits 
• Classification relative to the normal range (‘Low’, ‘Normal’ or ‘High’) 
• Treatment-Emergent potentially clinically significant (PCS) abnormalities, if 
applicable 
Abnormalities in liver tests will be identified. 
In addition, 25-hydroxyvitamin D, rheumatoid factor (RF), anti-cyclic citrullinated peptide 
(anti-CCP) antibodies and serum immunoglobulins G, M and A (IgG, IgM and IgA), viral 
serology, drugs of abuse and alcohol screen, pregnancy test and follicle stimulating hormone 
will also be obtained at the corresponding scheduled visit, respectively. 
5.3.7 Vital Signs 
Vital signs and body weight are collected as scheduled in Table 1. Vital signs include 
systolic/diastolic blood pressure, pulse rate, respiratory rate and body temperature (°C). 
Subjects must rest in a sitting position for at least 5 minutes in preparation for blood pressure and 
pulse rate assessments. The following information will be derived for all vital signs and body 
weight: 
• Change from baseline at all post-baseline visits 
• Treatment-emergent PCS abnormalities, if applicable 
5.3.8 12-Lead ECG 
Twelve-lead ECG recordings and conduction intervals including RR, PR, QRS, QT are 
obtained according to the schedules summarized in Table 1. The Fridericia-corrected QT 
interval (QTcF) (Fridericia’s formula, QTcF = QT/RR1/3) will be calculated and reported. The 
following information will be derived for each of the 12-lead ECG measurements: 
• Change from baseline to all post-baseline visits 
• Treatment-emergent PCS abnormalities, if applicable 
The overall clinical interpretation of an ECG is assessed as follows: normal, abnormal not 
clinically significant or abnormal clinically significant.  
5.3.9 Physical examination 
Physical examination is conducted as scheduled in Table 1. The physical examinations include 
examination of the following body systems: general appearance, skin (including hair and 
nails), HEENT (head, ears, eyes, nose, throat), neck/thyroid, chest/lungs, cardiovascular, 
gastrointestinal (GI), 
, psychiatric/emotional, lymphatic and musculoskeletal. 
Clinically significant abnormal physical examination findings will be recorded as medical 
history or AE where appropriate.

Trough concentrations of JTE-051 are measured from visit 3 to visit 6 during the treatment 
period.  
The relationship between the JTE-051 dose (exposure) and response will be assessed 
(exploratory). 
Medications/Procedures 
At each study visit, investigators will review concomitant medications and procedures with the 
patients. The World Health Organization (WHO) Drug Dictionary March 2018 will be used to 
classify medications by preferred term, chemical ingredient names and WHO Level 3 
Anatomical Therapeutic Chemical (ATC) classification of trade name. Medication records will 
be characterized as prior medication and/or concomitant medication based on the subjects’ 
start and end date of the study drug. 
5.4.1 Prior Medications/Procedures 
Prior medications/procedures are defined as any medications/procedures started and ended 
before the first dose of the study drug. 
5.4.2 Concomitant Medications/Procedures 
Any medications/procedures that begin before the start of the first dose of study drug and 
continue past that, or that begins on or after the first dose of study drug and up to 28 days post 
the date of the last dose of the DB medications will be considered as concomitant 
medications/procedures. 
6. STATISTICAL METHODOLOGY 
Titles and headers of all statistical analysis tables will indicate the corresponding study 
population; the number of subjects for the population and for each treatment will be presented 
in the tables. Summary statistics for continuous parameters will include the number of subjects 
(N), mean, standard deviation (SD), median, minimum and maximum. For plasma 
concentrations, summary statistics will also include the coefficient of variation (CV%). 
Summary statistics for discrete parameters will include frequency count and percentage of 
which the denominator will be clearly indicated in the analysis table.  
For efficacy and safety summaries, mean and median will be presented to 1 more decimal than 
the source data; SD will be presented to 2 more decimals than the source data; minimum and 
maximum will be presented in the same precision as the source data. Percentages including 
response rate will be presented to 1 decimal, e.g., xx.x%. P-values will be presented to 3 
decimals. P-values greater than 0.999 will be presented as >0.999; p-values less than 0.001 
will be presented as <0.001.  
For figures, the corresponding study population will be included in the titles. All collected 
observations will be included in the related listings. 
Baseline value is defined as the last non-missing value prior to the first dose.

For the safety and efficacy analyses, only assessments from scheduled visits will be used for 
summary tables, however, data collected from both scheduled and unscheduled visits will 
appear in the subject listings.  
When calculating percent change from baseline in efficacy analyses, measures scored as 0 at 
baseline will be managed as missing values when they did not change from 0, and as 0% change 
when they were increased (i.e., worsened). 
Sample Size
Approximately 250 eligible subjects (50 in each treatment group) are randomized into the DB 
treatment period of this study. 
The primary efficacy evaluation will be to compare the ACR20 response rate between JTE-051 
with placebo at EOT. From one study comparing mavrilimumab with placebo in combination 
with stable MTX, the ACR20 of mavrilimumab and placebo at Week 12 were 0.69 and 0.40, 
respectively. Assuming the ACR20 of at least one of the JTE-051 doses to be at least 0.30 
above placebo, the following sample size per group will be needed to detect a statistical 
significant difference at the 5% level with about 80% power (using 2-sided Fisher’s exact test):
About 50 randomized subjects per group would therefore give at least an 80% power for a 
range of placebo responses. The sample size calculation was carried out using the software 
SiZ 6.2 (Cytel Inc., 2013). 
Subject Disposition Summary
Patient disposition will be summarized and tabulated by treatment group and in total. The 
number and percentage of patients in the randomized, safety, ITT, PP and PK populations will 
be tabulated. Discontinued patients and the reasons for discontinuation during the screening, 
DB treatment, or follow-up periods will be tabulated for the randomized population by 
treatment group and in total. 
Demographics and Baseline Characteristics 
Demographics and baseline characteristics as defined in Section 5.1 will be presented by 
treatment group with descriptive statistics for the randomized, safety, ITT and PP populations.
Efficacy Analysis 
Analyses of primary and secondary efficacy parameters will be performed for both the ITT 
and PP populations, respectively.  
For efficacy analyses, the DB treatment period is defined as the time period from the first dose 
of study drug to the last dose of study drug plus 4 days. The end of treatment (EOT) value is 
defined as the last value taken during the DB treatment period.

6.4.1 Analyses of Primary Efficacy Endpoint 
For the primary efficacy parameter (ACR20 response rate at EOT), the Fisher’s exact test will 
be used to compare each JTE-051 dose group with placebo. Furthermore, the exact 
Cochran-Armitage trend test will also be performed, using the ordinal score for treatment, 
e.g., score 1 for placebo, score 2, 3, 4 and 5 will be used to represent JTE-051 50 mg, 100 mg, 
150 mg and 200 mg, respectively.

                        run; 
In addition, logistic regression model-based analyses will be performed for the pairwise 
comparisons between JTE-051 and placebo groups (Model 1) and for the evaluation of dose 
response relationship (Model 2). The logistic regression models will include the baseline PGA 
score, hs-CRP and region as a covariate.

• 
In Model 2, Dose = 0, 50, 100, 150, 200 for placebo and each JTE-051 dose level, respectively. 
• 
ACR20 is a 0, 1 variable; i.e., ACR20=1 represents a responder; ACR20=0 represents a 
non-responder.  
• 
Regionn=0 represents ‘EMEA’; Regionn=1 represents ‘Latin America’ or ‘North America’; 
• 
Hscrpn=0 represents screening hs-CRP<=2 x upper limit of normal (ULN); Hscrpn=1 represents 
screening hs-CRP>2 x ULN. 
• 
From the model fitting, one obtains adjusted odds ratios and corresponding p-values for the 
respective pairwise treatment comparison versus placebo.

6.4.2 Analyses of Secondary Efficacy Endpoints  
For dichotomous secondary efficacy parameters, similar analyses as the primary efficacy 
parameter will be used by time point, i.e., the Fisher’s exact test for pairwise comparisons with 
placebo and the Cochran-Armitage test for trend. 
For continuous efficacy parameters, the mixed model with fixed effects for treatment, time, 
treatment by time interaction, the stratification factors and the baseline, and measurements 
within each subject as repeated measures will be used. 
6.4.3 Supportive Analyses of Efficacy Parameters  
For dichotomous efficacy parameter analysis with multiple time points, a supportive analysis 
will be performed using a generalized estimating equation (GEE) method on the logit scale. 
The model includes effects for treatment, time, treatment by time interaction, stratification 
factors and subject as the repeated factor. The odds ratio (OR) of each JTE-051 dose group 
relative to placebo at the same time point will be estimated.  
Model: (generalized estimating equation (GEE) method on the logit scale) 
                   proc genmod data=xxx; 
                            class usubjid trtn(ref=1) region(ref=0) hscrpn(ref=0);

                            repeated subject=usubjid/type=un corrw; 
                  run; 
Note:  SAPE denotes any dichotomous efficacy parameter, regionn and hscrpn  are  stratification factors, we can 
add other stratification when needed. 
The supportive efficacy parameters utilizing the non-hs-CRP will be analyzed in a similar 
manner as their secondary efficacy counterparts using hs-CRP. 
All analyses will be performed two-sided at the 5% significance level. No formal multiple 
comparison adjustment will be made; therefore, results should be interpreted with the 
multiplicity in mind. The estimated treatment effect (relative to placebo), e.g., odds ratio, from 
the model, along with a two-sided 95% confidence interval (CI) and p-value, will be tabulated 
where appropriate. The Newcombe’s CI of the rate difference between JTE-051 dose and 
placebo will be computed when performing the Fisher’s exact test. Graphical presentations of 
the treatment profile will be depicted for the primary and key secondary analyses. Sensitivity 
analysis and model fit assessment may be conducted, and data transformation may be 
employed if appropriate. 
6.4.4 Descriptive Summary Statistics for Efficacy Parameters 
Descriptive statistics of efficacy parameters over time will be presented by treatment. They 
will include N, arithmetic mean, SD, median, minimum and maximum for continuous 
parameters and in frequency tabulation form for dichotomous parameters.

centers will be used and only a small number of subjects will be enrolled in most centers. The 
region effect will be assessed with respect to the primary efficacy parameter and may be 
included in the analysis model where appropriate.

Treatment by Baseline Covariate Effect  
The treatment-by-baseline effect is not considered; however the baseline will be included in

6.4.9 Subgroup Analysis  
Subgroup analyses may be performed as appropriate upon reviewing the results of the primary 
analyses. 
 
6.4.10 Handling of Dropouts and Missing Data 
For the analyses of dichotomous efficacy parameters by time point, subjects with missing data 
will not be included in the analysis.  
For the analyses of dichotomous efficacy parameters with multiple time points, any missing 
data will be imputed using the last observation carried forward (LOCF) method except for 
subjects who withdraw for treatment-related AEs, in which case, any value after the 
treatment-related withdrawal will be imputed as non-responsive.  
For missing data handling in the calculation of ACR20/50/70 responses, because the ACR20 
is a composite value, it is sometimes possible to determine it even if there are any missing 
components. For example, if there is non-responsiveness in at least one of the tender/painful 
joint count or the swollen joint count, then the ACR20/50/70 is non-responsive. However, if 
there are missing values in 1 or 2 of the 5 remaining ACR core set components, the method of 
last observation carried forward (LOCF) will be used to carry forward any of the missing 
components, and from that mix of actual and carried-forward values, the ACR20/50/70 will be 
determined. If 3 or more of 5 components are missing, then the corresponding ACR response
will not be calculated, and the value of ACR response is considered missing. Missing 
component at the follow-up visit (Week 16) will not be imputed. 
For continuous efficacy parameters, no imputation will be employed. 
For the calculation of duration (years) of active RA at Screening, January will be imputed if 
month of diagnosis is missing. 
Other missing data imputation methods may be employed for additional sensitivity analysis if 
deemed necessary. 
Safety Analysis
All safety analysis will be performed on the Safety population. 
Potentially clinically significant (PCS) abnormalities will be defined according to the Akros 
Safety Reporting Standards (Standard72.doc, 10/18/2004). The PCS values for vital signs, 
ECG and laboratory data will be flagged in data listings. 
Treatment-emergent PCS values will be summarized, presenting the number and percentage 
of subjects who had at least one PCS value on or after the first dose of study drug (JTE-051 or

placebo). The denominator is always the number of subjects in the safety population, regardless 
of whether the subject had any post-baseline measurements. The numerator is any PCS value 
in the treatment-emergent period if the baseline is normal or missing; and is any worsening 
PCS value in the treatment-emergent period if the baseline is also a PCS value. A worsening 
PCS is defined as a > (<) 0 change from baseline if a high (low) value indicating undesirable 
outcome; or the PCS value is in the opposite direction of the baseline PCS value. Note that for 
the purpose of determining PCS abnormalities, baseline is always the last non-missing value 
before the first dose of study drug. 
Adverse Events (AEs) 
The number and percentage of subjects experiencing TEAEs will be tabulated by treatment 
according to the following categories: 
• Overall summary of TEAEs.
• TEAEs by system organ class and preferred term.
• TEAEs leading to study discontinuation by system organ class and preferred term.
• TEAEs by system organ class, preferred term and AE severity.
• TEAEs by system organ class, preferred term and AE causality.
• TEAEs by preferred term (in order of descending frequency in the total JTE-051 group).
• Serious AEs (SAEs) by system organ class and preferred term.
• Serious AEs leading to study discontinuation by system organ class and preferred term.
Listings will be provided for SAEs and AEs leading to study discontinuation.
Medical History 
Subjects with significant medical history conditions and/or surgeries, the corresponding 
system organ class and preferred term coded from the MedDRA (version 21.0) will be 
presented in the data listing.
Clinical Laboratory Tests 
Descriptive statistics of observed results and change from baseline for hematology, 
coagulation, serum biochemistry, bone-specific alkaline phosphatase, lipid panel and 
continuous urinalysis will be presented by time point and treatment group. Frequency and 
percentage of the distribution of discrete urinalysis tests will be presented by time point. 
Number and percentage of subjects with treatment-emergent PCS abnormal values will be 
summarized by treatment group.  
Number and percentage of subjects with post-baseline abnormalities in liver tests will 
be summarized by treatment group according to Table 3.

Other clinical laboratory tests (e.g., drug abuse, alcohol screen, viral serology) will be listed in 
the data listings. 
Qualitative urine parameters are generally reported by a descriptive score, which may differ 
between laboratories. For pooling the data, a four-point scale is used. The five-point scale will 
be converted into a four-point scale by combining the lowest two positive results as shown in 
the table below. Furthermore, a clinical review will be performed on the mapping of the 
descriptive scores to the four-point scale; and the descriptive scores will be remapped where 
appropriate. The four-point scale will be used in the summary of the PCS abnormality analysis.
