E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
TO EVALUATE THE EFFICACY OF ATACICEPT COMPARED TO PLACEBO IN THE TREATMENT OF SIGNS AND SYMPTOMS IN A SUBJECT POPULATION WITH ACTIVE RA, INADEQUATE RESPONSE TO METHOTREXATE (MTX) AND NO PREVIOUS EXPOSURE TO ANTI TNF ALFA THERAPY |
|
E.2.2 | Secondary objectives of the trial |
- To evaluate the safety and tolerability profile of atacicept in treating anti-TNFα-naïve subjects with active RA and an inadequate response to methotrexate. - To gain further information on the effect of atacicept on biomarkers reflecting its mechanism of action (MoA) and disease activity. - To further characterise atacicepts pharmacokinetic (PK) and Pharmacodynamic (PD)profiles. |

E.3 | Principal inclusion criteria |
1. Rheumatoid arthritis satisfying American College of Rheumatology (ACR) criteria for RA (22); see Appendix B) with a disease history of at least 6 months. 2. Male or female ≥18 years of age at time of Informed Consent. Active RA as defined by: ≥8 swollen joints (66 joint count), ≥8 tender joints (68 joint count), and CRP ≥10 mg/L. 4. Persistent and active RA despite MTX treatment (≥ 15 mg/week) lasting for >3 months. 5. Stable MTX dose (15-25 mg) for at least the last 28 days before SD 1. 6. Written informed consent, obtained before any study-related procedure. Subjects must review and understand the Informed Consent Form, and must fully understand the requirements of the study and be willing to comply with all study visits and assessments. 7. Women of childbearing potential must have a negative urine pregnancy test at the screening visit. For the purposes of this trial, women of childbearing potential are defined as all female subjects after puberty unless they are post-menopausal for at least two years or are surgically sterile. 8. Female patients of childbearing potential must be willing to avoid pregnancy by using an adequate method of contraception for four weeks prior to, during and three months after the last dose study medication. Women randomized to adalimumab will be required to maintain an adequate method of contraception for at least 5 months after the last dose. For the purposes of this study, women of childbearing potential is defined as: All female patients after puberty unless they are post-menopausal for at least two years, or are surgically sterile. Adequate contraception is defined as two barrier methods, or one barrier method with a spermicide, or an intrauterine device or use of the oral female contraceptive (or other hormonal methods). |
