Study Details

Study Description

Brief Summary

The purpose of this study is to find biological response patterns of patients with rheumatoid arthritis to drugs with different biologic modes of action. This study should help to predict therapeutic responses and to find the right therapy for the right patient.

Condition or Disease	Intervention/Treatment	Phase
Rheumatoid Arthritis	Drug: Remicade Drug: Orencia Drug: Ro-Actemra Drug: Mabthera	Phase 4

Detailed Description

The investigators propose a randomised, multi-centre strategic biomarker trial of rheumatoid arthritis (RA) patients with failure to methotrexate or leflunomide to one of the four current biological modes of action: targeting TNF (infliximab); co-stimulation (abatacept); IL-6R (tocilizumab); and B cells (rituximab); all agents are licensed for RA and have evidence for efficacy in this indication. Predictors of response to therapy after 24 weeks will be analysed, and include baseline and follow up assessments of clinical, functional, structural, laboratory tests (routine, autoantibodies, cytokines, gene expression, and susceptibility genes). In a second phase, patients not achieving LDA/REM will be randomised to one of the remaining MoA. Two hundred patients, who are started on a new biological therapy will be enrolled over an estimated period of 5 years; 50 patients per group will be included, and studied for a period of 12 months.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Infliximab Infliximab (Remicade®) will be administered i.v.at a dose of 3 mg/kg at 0 and 2 weeks, and 5 mg/kg at weeks 6, 14, and 22, 30, 38, and 46.	Drug: Remicade - Infliximab (Remicade®) will be administered i.v. at a dose of 3 mg/kg at 0 and 2 weeks, and 5 mg/kg at weeks 6, 14, and 22, 30, 38, and 46.
Experimental: Abatacept Abatacept (Orencia®) will be given i.v. at weeks 0, 2, 4, and then every 4 weeks until week 48 at a weight adjusted dose: <60 kg Body weight (BW): 500 mg; >60-100 kg BW: 750 mg; alternatively, based on preference and shared decision between patient and physician, patients randomized to the abatacept arm may receive s.c.application at a dose of 125mg weekly.	Drug: Orencia - Abatacept (Orencia®) will be given i.v. at weeks 0, 2, 4, and then every 4 weeks until week 48 at a weight adjusted dose: <60 kg Body weight (BW): 500 mg; >60-100 kg BW: 750 mg; alternatively, based on preference and shared decision between patient and physician, patients randomized to the abatacept arm may receive s.c. application at a dose of 125mg weekly.
Experimental: Tocilizumab Tocilizumab (Ro-Actemra®) will be administered every 4 weeks at a dose of 8 mg/kg BW (maximum dose of 800 mg); The employed dosage will be calculated using manufacturer guidelines; alternatively, based on preference and shared decision between patient and physician, patients randomized to the tocilizumab arm may receive s.c. application at a dose of 162mg every week.	Drug: Ro-Actemra - Tocilizumab (Ro-Actemra®) will be administered every 4 weeks at a dose of 8 mg/kg BW (maximum dose of 800 mg); The employed dosage will be calculated using manufacturer guidelines; alternatively, based on preference and shared decision between patient and physician, patients randomized to the tocilizumab arm may receive s.c. application at a dose of 162mg every week.
Experimental: Rituximab Rituximab (Mabthera®) will be given as 1000mg at weeks 0 and 2, and then repeated at weeks 24 and 26. Patients will receive 100 mg methylprednisolon i.v. before each infusion, as well as 1000mg paracetamol, as well as 50mg diphenhydramine hydrochloride (Dibondrin©).	Drug: Mabthera - Rituximab (Mabthera®) will be given as 1000mg at weeks 0 and 2, and then repeated at weeks 24 and 26. Patients will receive 100 mg methylprednisolon i.v. before each infusion, as well as 1000mg paracetamol, as well as 50mg diphenhydramine hydrochloride (Dibondrin©).
