• Sex: All
• Target Recruitment: 240

Inclusion Criteria

1. Male and female subjects between the ages of = 18 years and = 80 years at the time of signing the ICF.
2. Meets the American College of Rheumatology (ACR, formerly American Rheumatism
Association) 1987 revised criteria for classification of RA at least 24 weeks prior to
screening.
3. ACR functional class I to III.
4. Active RA at the time of screening and at baseline consisting of = 6 swollen and
= 6 tender joints (28-joint count).
5. The hs-CRP = 8 mg/L at screening (as determined by blood specimen sent to the Central Lab).
6. Must be receiving MTX for at least 12 weeks, with a stable dose and route of MTX
(7.5 - 25 mg weekly) for at least 6 weeks prior to baseline and continuing on that dose for the duration of the study.
7. The report of a chest radiograph performed within 12 weeks of the screening visit (chest radiograph must be performed during the screening if no prior chest radiograph report is available) documenting the absence of any evidence of malignancy, infection, or abnormalities suggestive of tuberculosis must be obtained and available in the subject’s study file prior to baseline.
8. All women of childbearing potential (WOCBP) must have a negative serum pregnancy test result at screening and a negative urine pregnancy test result at baseline.
? WOCBP are defined as women who are biologically capable of becoming pregnant,
including women who are using contraceptives or whose sexual partners are either
sterile or using contraceptives.
? Women of non-childbearing potential (WONCBP) are defined as either
postmenopausal (history of amenorrhea for = 52 weeks) or who are surgically sterile, such as after hysterectomy, bilateral oophorectomy, or tubal ligation (procedure performed = 52 weeks before screening). This information must be documented in the subject’s source documents.
? WONCBP do not require a serum and urine pregnancy test.
9. All WOCBP who have sexual intercourse with a non-surgically sterilized male must
agree and commit to the use of hormone contraception, double barrier contraception, or an intrauterine device for the duration of the study (defined as the time of the signing of the ICF through the conclusion of subject participation). Double-barrier contraception is defined as the use of a diaphragm, suppository, or sponge.
? To be considered surgically sterilized, a male partner must have had a vasectomy at least 24 weeks before study day 1.
10. All men (unless surgically sterile, as defined above) who have sexual intercourse with a WOCBP must agree and commit to use a medically acceptable form of contraception for the duration of the study (defined as the time of the signing of the ICF through the conclusion of subject participation). Medically acceptable forms of contraception include properly used barrier forms of contraception.
11. Willingness and ability to participate in all aspects of the study, including SC
administration of investigational product (by unblinded study personnel), completion of subject assessments, attending scheduled clinic visits, and compliance with all protocol requirements as evidenced by written informed consent.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range

Exclusion Criteria

1. Pregnant women or nursing mothers.
2. Presence of active infections, fungal infections, or open cutaneous ulcers, any underlying diseases that could predispose subjects to infections, or history of serious infection (requiring parenteral antibiotic and/or hospitalization) within 4 weeks of baseline visit.
3. Significant concurrent, medical conditions at the time of screening or baseline visit
including, but not limited to:
? Any major illness/condition or evidence of an unstable clinical condition, such as,
renal, hepatic, hematological, gastrointestinal, endocrine, pulmonary, immunologic
(eg, Felty’s syndrome, human immunodeficiency virus [HIV], infections,
neurological, cerebral psychiatric disease, or evidence of demyelinating disease
which, in the investigator’s judgment, will substantially increase the risk associated with the subject developing an adverse event (AE) or serious adverse event (SAE)
during the study, or preclude the evaluation of the subject’s response.
? A history or current evidence of latent or active tuberculosis infection, evidence of
prior or currently active tuberculosis by chest radiography, recent close contact with
an individual with active tuberculosis, or a positive Mantoux tuberculin skin test
(= 5 mm of induration at 48-72 hours without consideration of prior Bacillus
Calmette-Guérin [BCG] vaccination or as defined by country specific guidelines or
local standards).
? A history or suspicion (received antibiotics) of a joint prosthesis infection if
prosthesis not removed or replaced.
? Any rheumatologic disease other than RA, including but not limited to Lyme disease, primary Sjögren’s syndrome, psoriatic arthritis, spondyloarthropathy, systemic lupus erythematosus, systemic vasculitis, polymyositis, infectious arthritis, reactive arthritis (Reiter’s syndrome), or scleroderma.
? Cancer or history of cancer or lymphoproliferative disease within previous 5 years
(other than resected cutaneous basal cell or squamous cell carcinoma that has been
treated with no evidence of recurrence).
? Class III or IV congestive heart failure as defined by the New York Heart Association
? Acute coronary syndrome (eg, myocardial infarction, unstable angina pectoris) and
any history of significant cerebrovascular disease within 24 weeks of screening.
? Have a transplanted organ.
? Documented history of any drug-induced liver injury, liver cirrhosis, or fibrosis at any time before baseline visit.
4. Abnormality in hematology or biochemistry profiles at screening:
? Positive hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), and hepatitis C antibody (HepCAb) with confirmation by recombinant immuno blot assay (RIBA).
? Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels
= 2 times the upper limit of normal (ULN).
? Hemoglobin levels = 85 g/L (8.5 g/dL).
? Platelet count = 125 x 10 power 9/L (125,000 cells/mm³) or = 1,000 x 10 power 9/L (1,000,000 cells/ mm³).
? White blood cell count = 3.5 x 10 power 9/L (3,500 cells/ mm³).
? Serum creatinine levels = 177 µmol/L (2 mg/dL).
5. Any prior use of B cell-depleting therapy.
6. All drugs which have efficacy in RA (excluding MTX) should be discontinued for
sufficient time that there is minimal systemic exposure or residual therapeutic activity.
A comprehensive but not exhaustive list of drugs and the duration they should be discontinued for prior to entering the study is provided in the clinical trial protocol exclusion criteria section.
