For subjects receiving non-steroidal anti-inflammatory drugs (NSAIDs) or low potency opioids (e.g. only tramadol, meperidine, and codeine allowed), including as needed (PRN) use: the subject must be on a stable dose for ≥ 4 weeks prior to initiation of IMP and be expected to maintain a stable dose for the first 24 weeks of the study, unless a change in dosage is required due to toxicity. Stable dose and PRN use are defined as subjects taking an NSAID or low potency opioids on average 4 days per week over the 4-week period prior to Screening. 9. Subjects receiving non-drug therapy (including but not limited to physical therapy, massage, diet, exercise, emollients, and joint taping) must be stable for the 4week period prior to IMP initiation through to the end of double blind study period (Week 24). 10. For subjects receiving methotrexate (MTX) or leflunomide: subject has received treatment for at least 3 months, with a stable dose and method of dosing (methotrexate: oral or subcutaneous injection; leflunomide: oral) (not to exceed 25 mg MTX per week or 20 mg leflunomide per day) for at least 8 weeks prior to initiation of IMP, and be expected to maintain a stable dose for the first 24 weeks of the study, unless a change in dosage is required due to toxicity. Subjects may not be receiving both leflunomide and MTX concomitantly. 11. For subjects receiving oral corticosteroids: the subject must be on a stable dose (not to exceed the equivalent of 10 mg of prednisone per day) for ≥ 4 weeks prior to initiation of IMP, and be expected to maintain a stable dose for the first 24 weeks of the study. 12. Subject has a negative evaluation for tuberculosis (TB) within 4 weeks before initiating IMP, defined as a negative QuantiFERON test. Subjects with a positive or 2 successive indeterminate QuantiFERON tests are allowed if they have all of the following: - no history of active TB or symptoms of TB, - a posterior-anterior (PA) chest radiograph (with associated report available at the site) performed within 3 months of Screening with no evidence of active TB (or of any other pulmonary infectious diseases), - if prior latent TB infection, must have history of adequate prophylaxis (per local standard of care), - if presence of latent TB is established, then treatment according to local country guidelines must have been followed for at least 4 weeks, prior to dosing in the study at visit 2-Week 0. A maximum of 2 QuantiFERON tests of no more than 3 weeks apart are allowed. A re-test is only permitted if the first is indeterminate; the result of the second test will then be used. |
