E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of ART621 on the signs and symptoms of moderate to severe RA in patients concomitantly taking methotrexate as assessed by the proportion of subjects achieving an ACR20 response after 12 weeks treatment. |
|
E.2.2 | Secondary objectives of the trial |
Evaluate the dose-response of ART621 against signs and symptoms of moderate to severe RA as assessed by proportion of subjects meeting ACR50 and ACR70 improvement criteria, changes in ACR hybrid score and individual ACR components, DAS28 response rate and DAS28 scores, LDAS analysis, erythrocyte sedimentation rate, C-reactive protein, individual dimensions of the Health Assessment Questionnaire and the patients assessment of fatigue. Evaluate safety, tolerability of ART621 (vital signs, ECG, clinical chemistry, haematology, urinalysis, physical examination and AE reporting). Assess impact of ART621 on quality of life as assessed by SF-36, RAQoL questionnaires. Assess immunogenicity profile of ART621 as assessed by development of human-anti-human antibodies. Investigate plasma concentration versus time profile and PK of ART621 in subjects with RA. Assess the effects of ART621 on immunological parameters and other disease biomarkers.

1. Valid written informed consent. 2. Male or female subjects ≥ 18 and ≤ 80 years old. 3. Women of childbearing potential, or men of fathering potential, must be using adequate birth control measures during the study. Female subjects of childbearing potential must test negative for pregnancy prior to enrolling in the study. Post menopausal women are eligible for this study. 4. Diagnosis of RA for at least 6 months and no longer than 3 years prior to screening. 5. Meet ACR functional class criteria I, II or III. 6. Have active RA at the time of screening and at baseline, defined as ≥ 6 swollen joints and ≥ 6 tender joints (from 68 joint count) together with at least 2 of the following 3 criteria: - CRP level ≥ 1.5 mg/dl; - ESR by Westergren method ≥ 28 mm in the first hour; or - morning stiffness ≥ 45 minutes. 7. At least one should be present at screening: -documented history or current presence of positive rheumatoid factor; - presence of serum anti-CCP antibodies; or screening radiographic erosion. 8. Have been tolerating concomitant methotrexate (oral or subcutaneous) for at least 3 months prior to screening and on a stable dose between 10-25 mg per week for at least 6 weeks prior to the first study dose. The route of administration must also be stable. Use of methotrexate dose of 25-50 mg every 2 weeks is also acceptable. (Other DMARDs taken concomitantly with methotrexate are not allowed. Those subjects concomitantly receiving additional DMARDs with methotrexate may enter the study by stopping the additional DMARD at least 4 weeks prior to first study dose). 9. If using the following medication, the subject must be on a stable dose for the 4 weeks prior to the first study dose and maintain that dose throughout the study: -oral corticosteroids, equivalent to ≤ 10 mg of prednisone/day. -one nonsteroidal anti-inflammatory drug (NSAID). -3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors (statins) or fibrates (see Protocol Section 7.1 for acceptable doses). 10. Does not have active or latent TB according to eligibility assessment and screening rules 11. Is willing and able to comply with study visits and other protocol requirements.

E.4 | Principal exclusion criteria |

Subjects who have previously failed to respond to any oral or injectable anti-TNFα therapy or subjects who have had to stop anti-TNFα therapy for safety reasons. Subjects who have successfully responded to anti-TNF therapy in the past (but discontinued for reasons other than safety or lack of efficacy) > 6 months prior to study day one may enrol. Patients who have participated in a previous anti-TNF therapy study are eligible if they are confirmed to have received placebo. 6. Subjects who have previously received the following anti-rheumatic drugs: interleukin-1 receptor antagonist [anakinra], rituximab, anti-CD4 antibody, abatacept, thalidomide, p38 MAP kinase inhibitor and other agents. 7. Subjects who have undergone plasmapheresis within 6 months prior to randomisation. 8. Have received intraarticular, intramuscular, or intravenous corticosteroids, including intramuscular adrenocorticotropic hormone, during the 4 weeks prior to the first study dose, or non-stable doses of oral steroids. 9. Subjects with a history of any clinically significant adverse reaction to murine or chimeric proteins, including serious allergic reactions. 10. Subjects with Felty’s syndrome or a history of Felty’s syndrome. 11. Subjects who have received or are expecting to receive any live virus or bacterial vaccinations within 1 month before first study dose, during the study, or up to 3 months after the study dose. 12. Subjects with a history of, presence of, or at high risk of serious infection including: -history of active TB, or positive Mantoux test or QuantiFERON Gold test or chest x-ray suggestive of active or healed TB or positive contact history with a subject with active TB within the past 3 months.
