Summary
The purpose of this study was to determine how effective and safe the study drug Olokizumab is, in patients with Rheumatoid Arthritis (RA) who were already receiving, but not fully responding to treatment with an existing medication called a tumour necrosis factor alpha inhibitor The primary objective of this study was to evaluate the efficacy of olokizumab (OKZ) 64 mg administered subcutaneously (SC) once every 2 weeks (q2w) or once every 4 weeks (q4w) relative to placebo in subjects with moderately to severely active rheumatoid arthritis (RA) inadequately controlled by TNF-α inhibitor (TNFi) therapy.

- Subjects willing and able to sign informed consent

- Subjects must have a diagnosis of adult onset RA classified by ACR/EULAR 2010 revised
classification criteria for RA for at least 24 weeks prior to Screening.

(If the subject was diagnosed according to ACR 1987 criteria previously, the Investigator
may classify the subject per ACR 2010 retrospectively, using available source data.)

- Treatment with oral, SC, or intramuscular (IM) MTX for at least 12 weeks prior to
Screening at a dose of 15 to 25 mg/week (or ≥10 mg/week if there is documented
intolerance to higher doses)

- The dose and means of administering MTX must have been stable for at least 6
weeks prior to Screening.

- Subjects must be willing to take folic acid or equivalent throughout the study.

- Subjects must have moderately to severely active RA disease as defined by all of the
following:

- ≥6 tender joints (68 joint count) at Screening and baseline; and

- ≥6 swollen joints (66 joint count) at Screening and baseline; and

- CRP above ULN at Screening based on the central laboratory results.

- Subjects must have a documented inadequate response to treatment (i.e., TNFi failure)
with ≥1 licensed TNFi following at least 12 weeks of therapy with that agent.
Inadequate response to treatment is classified as either:

- Primary failure: The absence of any documented clinically significant response;
or

- Secondary failure: Documented initial response with subsequent loss of that
response or partial response

Exclusion Criteria:

- Diagnosis of any other inflammatory arthritis or systemic rheumatic disease (e.g.,
gout, psoriatic or reactive arthritis, Crohn's disease, Lyme disease, juvenile
idiopathic arthritis, or systemic lupus erythematosus) (However, subjects may have

agents (e.g., CAMPATH, anti CD4, anti CD5, anti CD3, and anti CD19) with the exception
of rituximab, which is allowed if it was discontinued at least 24 weeks prior to
baseline (rituximab should not be discontinued to facilitate a subject's participation
in the study, but should instead have been previously discontinued as part of a
subject's medical management of RA).

- Prior use of bDMARDs, within the following windows prior to baseline (bDMARDs should
not be discontinued to facilitate a subject's participation in the study, but should
instead have been previously discontinued as part of a subject's medical management of

change in dosage within 2 weeks prior to baseline

- Prior documented history of no response to hydroxychloroquine and sulfasalazine

- Prior use of cDMARDs (other than MTX) within the following windows prior to baseline
(cDMARDs should not be discontinued to facilitate a subject's participation in the
study, but should instead have been previously discontinued as part of a subject's
medical management of RA):

1. 4 weeks for sulfasalazine, azathioprine, cyclosporine, hydroxychloroquine,
chloroquine, gold, penicillamine, minocycline, or doxycycline

a) subjects who are positive for hepatitis B surface antibodies (anti-HBs), but
negative for HBsAg and anti-HBc, will be eligible.

- Subjects with HIV infection

- Subjects with:

1. Suspected or confirmed current active TB disease or a history of active TB
disease.

2. Close contact (i.e., sharing the same household or other enclosed environment,

during the day) with an individual with active TB within 1.5 years prior to
Screening

3. History of untreated latent TB infection (LTBI), regardless of IGRA result at
Screening

i. Subjects with a history of untreated LTBI may be re-screened and enrolled if they
fulfill all 3 of the following criteria:

1. Active TB is ruled out by a certified TB specialist or pulmonologist who is
familiar with diagnosing and treating TB (as acceptable per local practice); 2. The
subject has completed at least 30 days of LTBI-appropriate prophylaxis prior to
baseline with agents recommended as preventative therapy for LTBI according to
country-specific/Centers for Disease Control and Prevention (CDC) guidelines
(treatment with isoniazid for 6 months is not an appropriate prophylactic regime for
this study and it should not be used); and 3. The subject is willing to complete the
entire course of recommended LTBI therapy d. Positive interferon-gamma release assay
(IGRA) result at Screening. If indeterminate, the IGRA can be repeated once during the
Screening Period. If there is a second indeterminate result, the subject will be
excluded.

i. Subjects with a positive IGRA result at Screening may be re-screened and enrolled
if they fulfill all 3 of the following criteria:

1. Active TB is ruled out by a certified TB specialist or pulmonologist who is
familiar with diagnosing and treating TB (as acceptable per local practice);

2. The subject has completed at least 30 days of LTBI-appropriate prophylaxis prior
to baseline with agents recommended as preventative therapy for LTBI according to
country-specific/CDC guidelines and

3. The subject is willing to complete the entire course of recommended LTBI therapy
ii. If a subject with a positive IGRA result at Screening has documented evidence
of completing treatment for LTBI with a treatment regime and treatment duration
that are appropriate for this study, the subject may be enrolled without further
prophylaxis if recommended by a certified TB specialist or pulmonologist who is
familiar with diagnosing and treating TB (as acceptable per local practice) and
no new exposure in close contact with an individual with active TB after
completing the prophylactic treatment is suspected

3. History or presence of concurrent severe and/or uncontrolled CV disorder
(including but not limited to acute coronary syndrome or stroke/transient
ischemic attack in the previous 3 months before Screening) that would, in the
Investigator's judgment, contraindicate subject participation in the clinical
study, or clinically significant enough in the opinion of the Investigator to
alter the disposition of the study treatment, or constitute a possible
confounding factor for assessment of efficacy or safety of the study treatment

amenorrhea as defined by the amenorrhea with underlying status [e.g., correlative age]
or 6 months of natural amenorrhea with documented serum follicle-stimulating hormone
levels >40 mIU/mL and estradiol <20 pg/mL) who are not willing to use a highly

method of contraception during the study and for at least 3 months after the last
administration of study treatment.

Highly effective contraception is defined as:

- Female sterilization surgery: hysterectomy, surgical bilateral oophorectomy (with or
without hysterectomy) or tubal ligation at least 6 weeks prior to the first dose of
study treatment

- In the case of oophorectomy alone, only when the reproductive status of the woman
has been confirmed by documented follow-up hormone level assessment

- Total abstinence if it is the preferred and constant lifestyle of the subject. Thus,
periodic abstinence such as ovulation, symptothermal, postovulation, calendar methods,
and withdrawal are not acceptable methods of contraception.

- Male sterilization surgery: at least 6 months prior to Screening (with the appropriate
postvasectomy documentation of the absence of sperm in the ejaculate). For female
subjects, the vasectomized male should be the only partner.

- Placement of established intrauterine device (IUD): IUD copper or IUD with
progesterone

murine monoclonal antibodies

- Subject's unwillingness or inability to follow the procedures outlined in the
protocol

- Other medical or psychiatric conditions or laboratory abnormalities that may
increase potential risk associated with study participation and administration of
investigational products, or that may affect study results interpretation and, as
per the Investigator's judgment, make the subject ineligible
