- •Male or female patient aged ≥ 18 years and ≤ 80 years at the time of signing informed consent.
- •Patients with moderately to severely active RA for at least 6 months’ duration, defined as per the ACR Criteria, 1987 revision. Active RA is defined as having:: • SJC ≥10 out of the 66 joints count • TJC ≥12 out of the 68 joints count, and • CRP of at least 1.0 mg/dl determined using a highly sensitivity assay.
- •Patient must be on MTX and folic acid for at least 3 months prior to the first dose of study drug with the below requirements. o Must have been treated with stable doses of MTX (at least 15 mg/ week; at least 6 mg/ week for patients from other Eastern Asia countries, not exceeding allowed maximum dose in the country-specific label) for at least 4 weeks prior to randomisation. o Patients who cannot tolerate higher dose of MTX should be on stable and tolerable dose of MTX for 4 weeks prior to randomisation (there should be documented evidence of intolerance to MTX). o Patients taking MTX must be on a stable dose of folic acid (≥5 mg per week) or equivalent for at least 4 weeks prior to randomisation
- •Patient should not be on cDMARDs other than MTX for at least 4 weeks prior to the first dose of study drug (4 weeks’ prior for azathioprine, sulfasalazine; 8 weeks for hydroxychloroquine and chloroquine; 12 weeks for leflunomide; 24 weeks for cyclophosphamide).
- •Patients should not be on bDMARDs: these agents should have been discontinued at least 4 weeks (4 weeks prior for TNF alpha inhibitors; 24 weeks for rituximab; 4 weeks or half of biological half-life for other bDMARDs whichever is longer) prior to the first dose of study drug.
- •Patient on glucocorticoids should not be receiving more than 10 mg oral prednisone/ prednisolone or equivalent per day, and those receiving should be using stable dose for at least 6 weeks prior to randomisation.
- •For patient receiving non-steroidal anti-inflammatory drugs (NSAIDs) for the last 4 weeks prior to randomisation: a. Should be taking a stable dose NOT higher than the maximum recommended dose for the agent in the Prescribing Information of the country where the study centre is located. b. NSAIDs are allowed except for the 12h before the efficacy scheduled assessment visit (24h for oxicams and other single daily dose or less frequently administered agents); Details of permitted and prohibited medication in the current study has been captured at Section 6.
- •Women of childbearing potential should have a negative pregnancy test and should agree to use highly effective measures of contraception and not to donate or cryopreserve ova during the course of the study and for at least 6 months after the last dose of the study drug. OR Male patient permanently sterile by bilateral orchidectomy or agree to use appropriate contraception methods (see list in the Note below) and not to donate or cryopreserve sperm during the study and for at least 6 months after the last dose of study drug.

- •5 Patients who need concomitant RA therapies other than a. MTX with folic acid (at a dose of at least 5 mg per week [or equivalent]) (MTX and folic acid will be kept at a stable dose during the study); Folinic acid at the same dose of folic acid, can be given in place of folic acid if it is allowed by the local label. Patient should take the same folate supplementation throughout the duration of the study. b. NSAIDs at approved doses kept at stable doses during the study; c. Corticosteroids at a maximum daily dose of 10 mg of oral prednisone or equivalent kept stable during the study; or Also, patients who cannot maintain an analgesics-free period of appropriate duration (12 hr for analgesics in general; 24 hr for oxicams and other single daily or less frequently administered drugs) before patient evaluation visit. Note: Aspirin at anti-aggregant doses (up to 325 mg per day) is not considered as an analgesic.
