简要总结
The purpose of this study is to assess the effectiveness of treatment in patients with active rheumatoid arthritis who are having an inadequate response to at least 3 months of treatment with etanercept or adalimumab in addition to methotrexate.
详细描述
This is a Phase 4, multi center, open-label, assessor blinded, switch study of infliximab in patients with active rheumatoid arthritis who are receiving methotrexate and are having an inadequate response to their current treatment with etanercept or adalimumab. The last dose of etanercept must have been at least 1 week but not more than 2 weeks prior to the first infliximab study infusion. The last dose of adalimumab must have been administered at least 2 weeks but not more than 4 weeks prior to the first infliximab study infusion. The study will be conducted for 30 weeks and will include 200 patients. All eligible patients will receive 3 mg/kg infliximab infusions (drug given into a vein) at weeks 0, 2, and 6 and every 8 weeks thereafter, if they achieve a European League Against Rheumatism (EULAR) response on their current dose of infliximab. Patients who do not achieve a EULAR response will increase their dose from 3mg/kg to 5 mg/kg at week 14. Patients who do not achieve a EULAR response at week 22 will increase from either 3 mg/kg to 5 mg/kg or from 5mg/kg to 7 mg/kg. The last study infusion will take place at week 22. The last study visit for effectiveness evaluations will take place at week 26. A week 30 follow-up visit will be performed for adverse events and tuberculosis evaluations, health economics assessments, and review of concomitant medications. All patients who end the study early will be required to complete all assessments. Patients will receive 3 mg/kg infliximab infusions at weeks 0, 2, and 6. If patients achieve European League Against Rheumatism (EULAR) response, they will remain on their current dose. Patients who do not demonstrate a EULAR response will increase their infliximab dose from 3 mg/kg to 5 mg/kg at week 14. At week 22, patients will also increase their infliximab dose from 3 mg/kg to 5mg/kg or from 5 mg/kg to 7mg/kg if they do not demonstrate a EULAR response.

结局指标
主要结局
Percent of Patients Who Achieved a EULAR (The European League Against Rheumatism) Response at Week 10
时间窗: Week 10
Percent of patients who achieved EULAR response at Week 10. EULAR response is defined based on the DAS28 score and the EULAR response criteria (Van Gestel et al, 1996 and 1999). At a given visit, patients with a DAS28 score of ≤ 5.1 are considered EULAR responders if the improvement from baseline in their DAS28 score is greater than 0.6; Or patients with a DAS28 score \> 5.1 are considered EULAR responders if the improvement from baseline in their DAS28 score is \> 1.2.
次要结局
- Percent of Patients Who Acheived EULAR Response at Week 10 and Maintained Through Week 26 Without Infliximab Dose Increase(Week 26)
- Percent of Patients Who Achieved EULAR Response at Week 26, Regardless of EULAR Response Status at Weeks 10, 14, and 22, With or Without Dose Increase Prior to Week 26(Week 26)
- Change From Baseline in Physical Function (HAQ)(Week 26)
- Percent of Patients Who Achieved ACR20 at Week 10(Week 10)
- Percent of Patients Who Achieved ACR20 at Weeks 26.(Week 26)
