E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is 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 methotrexate (MTX) therapy. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the efficacy of OKZ relative to adalimumab in subjects with moderately to severely active RA inadequately controlled by MTX therapy (for EU submission).
To evaluate the efficacy of OKZ over time
To compare the physical function and quality of life of subjects receiving OKZ relative to placebo
To assess exposure to OKZ
To assess the safety and tolerability of OKZ |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Male or female subjects ≥18 years of age
2. Subjects willing and able to sign informed consent
3. Subjects must have a diagnosis of adult-onset RA classified by ACR/EULAR 2010 revised classification criteria for RA for at least 12 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.
4. Inadequate response to treatment with oral, SC, or intramuscular (IM) MTX (as defined by protocol) for at least 12 weeks prior to Screening at a dose of 15 to 25 mg/week (or ≥10 mg/week if intolerant to higher doses). The dose and means of administering MTX must have been stable for at least 6 weeks prior to Screening.
5. Subjects must have moderately to severely active RA disease as defined by all of the following:
a. ≥6 tender joints (68-joint count) at Screening and baseline; and
b. ≥6 swollen joints (66-joint count) at Screening and baseline; and
c. CRP above ULN at Screening based on the central laboratory results |
|
E.4 | Principal exclusion criteria |
1. 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 secondary Sjogren’s syndrome or hypothyroidism
2. Subjects who are Steinbrocker class IV functional capacity (incapacitated, largely or wholly bed-ridden or confined to a wheelchair, with little or no self-care)
3. Prior exposure to any licensed or investigational compound directly or indirectly targeting IL-6 or IL-6R (including Janus kinases and spleen tyrosine kinase [SYK] inhibitors)
4. Treatment with any cell-depleting therapies including anti-CD20 or investigational agents (e.g., CAMPATH, anti-CD4, anti-CD5, anti-CD3, and anti-CD19)
5. Past history of exposure to TNFi therapy
6. Use of parenteral and/or intra-articular glucocorticoids within 4 weeks prior to
baseline
7. Use of oral glucocorticoids greater than 10 mg/day prednisone (or equivalent) or change in dosage within 2 weeks prior to baseline
8. Prior history of no response to hydroxychloroquine and sulfasalazine
9. Prior use of DMARDs other than MTX is allowed with the following washout periods to be completed prior to baseline:
a. 4 weeks for sulfasalazine, azathioprine, cyclosporine, hydroxychloroquine,
chloroquine, gold, penicillamine, minocycline, or doxycycline
b. 12 weeks for leflunomide unless the subject has completed the following
elimination procedure at least 4 weeks prior to baseline: Cholestyramine at a
dosage of 8 grams 3 times daily for at least 24 hours, or activated charcoal at a
dosage of 50 grams 4 times a day for at least 24 hours
c. 24 weeks for cyclophosphamide
10. Vaccination with live vaccines in the 6 weeks prior to baseline or planned vaccination with live vaccines during the study

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is the American College of Rheumatology 20% (ACR20) response at Week 14, where a responder is defined as any subject satisfying ACR20 criteria and remaining on randomized treatment and in the study at Week 14. This endpoint will serve to demonstrate that the efficacy of OKZ is superior to placebo. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
For EU submission: ACR20 response at Week 14, where a responder is defined as any subject satisfying ACR20 criteria and remaining on randomized treatment and in the study at Week 14. This endpoint will serve to demonstrate that the efficacy of OKZ is non-inferior to adalimumab, provided that superiority of adalimumab to placebo (assay sensitivity) is demonstrated concurrently based on the same endpoint
Difference between OKZ and placebo in the percentage of subjects achieving low disease activity, defined as Disease Activity Score 28-joint count (DAS28) C-reactive protein (CRP) <3.2, and remaining on randomized treatment and in the study at Week 14
Difference between OKZ and placebo in the improvement of physical ability from baseline to Week 14, as measured by the Health Assessment Questionnaire-Disability Index (HAQ-DI)
Difference between OKZ and placebo in the percentage of subjects achieving an American College of Rheumatology 50% (ACR50) response and remaining on randomized treatment and in the study at Week 24
Difference between OKZ and placebo in the percentage of subjects with Simplified Disease Activity Index (SDAI) ≤3.3 (remission) and remaining on randomized treatment and in the study at Week 24 |
