E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
To be included in the study, each individual must satisfy all the following criteria: 1. Male or female adults, ≥ 18 years of age at time of informed consent. 2. Written informed consent and any locally required authorization obtained from the subject prior to performing any protocol-related procedures, including screening evaluations. 3. Diagnosed with Rheumatoid Arthritis (RA) according to the European League Against Rheumatism / American College of Rheumatology (EULAR/ACR) 2010 criteria ≥ 6 months prior to screening. 4. Disease Activity Score in 28 Joints Using C-reactive Protein (DAS28-CRP) > 3.2 at screening with ≥ 4 tender joint count (TJC) and ≥ 4 swollen joint count (SJC) out of the 28 joints assessed for DAS28 present at screening and confirmed present at Visit 2 prior to randomization. 5. Positive for rheumatoid factor (RF) and/or anti-citrullinated protein antibodies (ACPA) at screening, in accordance with criteria at the central laboratory. 6. Treated with methotrexate (MTX) given orally, subcutaneous (SC), or intramuscularly at a dose of 7.5-25.0 mg/week, with or without a concomitant disease-modifying anti-rheumatic drug (cDMARD) other than leflunomide, with MTX and the cDMARD delivered by the same route for ≥ 12 weeks without change in dose for ≥ 6 weeks prior to screening, OR, if MTX intolerant or if MTX is contraindicated, treated with one or more cDMARD for ≥ 12 weeks without change in dose for ≥ 6 weeks prior to screening. (Janus kinase (JAK) inhibitors are not considered cDMARDs). 7. Willing and able to comply with the protocol, complete study assessments, and complete the study period. 8. Females of childbearing potential who are sexually active with a non-sterilized male partner must use a highly effective method of contraception from signing informed consent and must agree to continue using such precautions through the end of the follow-up of the study; cessation of contraception after this point should be discussed with a responsible physician. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. A recommendation that the female partners (of childbearing potential) of male study participants should use a highly effective method of contraception other than a barrier method will be made. a. Females of childbearing potential are defined as those who are not surgically sterile (ie, surgical sterilization includes bilateral tubal ligation, bilateral oophorectomy, or hysterectomy) or those who are not postmenopausal (defined as 12 months with no menses without an alternative medical cause and a follicle-stimulating hormone within the postmenopausal range as established by the clinical laboratory). b. Because some of the background medications used in RA and accepted in the current study (eg, MTX or leflunomide) are known to have potential deleterious effects on conception, pregnancy, and fetal health, the Investigator must inform the subjects about these risks and should manage every case of planned conception or pregnancy according to the local medical practice standards. c. Non-sterilized male subjects who are sexually active with a female partner of childbearing potential must use a condom with spermicide from Day 1 through to the end of the study.

E.4 | Principal exclusion criteria |
Any of the following excludes an individual from participation in the study: 1. Prior or current (1) inflammatory joint disease other than RA; (2) other systemic autoimmune disorder or polymyalgia rheumatica except that patients with RA and secondary Sjögren’s syndrome may enroll. 2. Severe interstitial lung disease. 3. Prior receipt of any biologic B-cell-depleting therapy. 4. Receipt of any anti-TNFα biologic agent < 8 weeks prior to screening. 5. Receipt of any biological (b) DMARD with a mechanism of action other than direct TNF blockade, including any JAK inhibitor, <12 weeks or <5 half-lives of the drug (whichever is longer) prior to screening. 6. Receipt of any experimental therapy <12 weeks or <5 half-lives of the drug (whichever is longer) prior to screening. 7. Injectable corticosteroids (including intraarticular) or treatment with >10 mg/day dose of oral prednisolone or equivalent within 4 weeks prior to screening. Concomitant treatment with oral corticosteroids ≤10 mg/day prednisone or equivalent is permitted provided that the dose is stable for ≥4 weeks prior to screening and during the screening period and is expected to remain stable for the duration of the treatment period. Inhaled or topical corticosteroids given for asthma, chronic obstructive pulmonary disease, or dermatological conditions are allowed, provided doses are expected to be stable during the study. 8. Previous treatment with anti-CD40L compounds at any time before randomization. 9. History of confirmed deep venous thrombosis or arterial thromboembolism within 2 years of enrollment OR history of recurrent deep venous thrombosis or arterial thromboembolism OR patients with risk factors for venous thromboembolism or arterial thrombosis, prothrombotic status (including, but not limited to, known congenital or inherited deficiency of antithrombin III, protein C, protein S, or confirmed diagnosis of catastrophic antiphospholipid syndrome). 10. Treatment with anticoagulant drugs. Low-dose aspirin treatment (up to 325 mg/day) is allowed. 11. History of solid organ or cell-based transplantation. 12. Active malignancy or history of malignancy that was active within the last 15 years, with exceptions as defined in the protocol. 13. Pregnancy, lactation, or planning to become pregnant during the duration of the study. 14. Positive test for, or prior treatment for, hepatitis B, hepatitis C, or HIV infection. A positive test for hepatitis B is detection of either (1) hepatitis B surface antigen (HBsAg); or (2) hepatitis B core antibody (anti-HBc). 15. Evidence of active tuberculosis (TB) or being at high risk for TB based on criteria defined in the protocol. 16. History of (a) more than one episode of herpes zoster in the 12 months prior to screening or (b) any opportunistic infection in the 12 months prior to screening, excluding localized mucocutaneous candidiasis. 17. Known history of severe allergy or reaction to any component of the IP formulation. 18. Severe cardiovascular, respiratory, endocrine, gastrointestinal, hematological, neurological, psychiatric, or systemic disorder or any other condition that, in the opinion of the Investigator, would place the patient at unacceptable risk of complications, interfere with evaluation of the IP, or confound the interpretation of patient safety or study results.Subjects should be assessed for epidemiologic risk of COVID-19 (recent exposures, high-risk housing) and for health-related risk of COVID-19 severity based on current understanding of risk factors for severe disease when making a decision regarding the individual subject's risk of participation. Subjects who have active COVID-19 infection or disease or other significant infection, or, in the judgment of the investigator, who may be at unacceptable risk of COVID-19 or its complications should not be randomized. Ensure that the subject has a documented negative SARS-CoV-2 test within two weeks prior to randomization. Subjects with a positive test for SARS-CoV-2 may be rescreened at least 2 weeks after a positive test if asymptomatic and at least 3 weeks after symptomatic COVID-19 illness. 19. Inflammatory osteoarthritis. 20. Receipt of live vaccine or live therapeutic infectious agent within the 4 weeks prior to screening. 21. Blood tests at screening that meet any of the criteria defined in the protocol. 22. History of alcohol or drug abuse that, in the opinion of the Investigator, might affect patient safety or compliance with visits, or interfere with safety or other study assessments.
Repeat of screening laboratory tests: Repeat of study safety laboratory tests is acceptable if initial screening result is outside of acceptable limits; repeat tests must be conducted in line with the parameters defined in the protocol. Rescreening Procedures: Patients may be rescreened once if, in the Investigator’s judgment, the reason for ineligibility is likely to have resolved at the time of rescreening. |
