A Study to Compare the Response to Treatment With Abatacept vs Adalimumab, on Background Methotrexate, in Adults With Early, Seropositive, and Shared Epitope-positive Rheumatoid Arthritis and an Inadequate Response to Methotrexate
A Randomized, Head-to-head, Single-blind Study to Compare the Response to Treatment With Subcutaneous Abatacept vs Adalimumab, on Background Methotrexate, in Adults With Early, Seropositive Rheumatoid Arthritis Who Have "Shared Epitope" HLA Class II Risk Alleles and Have an Inadequate Response to Methotrexate

Brief Summary
The purpose of this study is to evaluate the superiority in efficacy of abatacept compared with adalimumab, on background methotrexate, in adults with early, seropositive, and shared epitope-positive rheumatoid arthritis and an inadequate methotrexate response.

Outcome Measures
Primary Outcomes (1)
Percentage of SE+ Participants Meeting 50% Improvement in American College of Rheumatology Criteria (ACR50) Response at Week 24
The ACR 50 definition of improvement is a 50% improvement over baseline in tender and swollen joint counts (#1 and #2) and a 50% improvement in 3 of the 5 remaining core data set measures (Participant global assessment of pain, participant global assessment of disease activity, physician global assessment of disease activity, participant assessment of physical function, and acute phase reactant value). Baseline value is the last assessment taken prior to first dose of single-blind study medication.
Baseline, week 24
Secondary Outcomes (34)
Percentage of SE+ Participants Achieving Disease Activity Score 28 Joint Count Calculated Using C Reactive Protein Remission (DAS28-CRP < 2.6) at Week 24
Week 24
Percentage of Participants Meeting 50% Improvement in American College of Rheumatology Criteria (ACR50) Response at Week 24
Baseline, week 24
Percentage of SE+ Participants Achieving Clinical Disease Activity Index Remission (CDAI <= 2.8) at Week 24
Week 24
Adjusted Mean Change From Baseline in SE+ Participant-Reported Pain Visual Analog Scale (VAS) at Week 24
Baseline, week 24
Percentage of SE+ Participants Meeting 20% Improvement in American College of Rheumatology Criteria (ACR20) Response Over Time
Baseline, day 29, 57, 85, 113, 141, 169
- +29 more secondary outcomes
Study Arms (2)
Arm 1: Abatacept + Methotrexate
EXPERIMENTALArm 2: (Adalimumab + Methotrexate) followed by (Abatacept + Methotrexate)
EXPERIMENTALInterventions
Abatacept SC (125 mg) once weekly
Adalimumab SC (40 mg) once every 2 weeks
Methotrexate oral/parenteral maximum tolerated dose (minimum 15 mg and maximum 25 mg weekly)
Eligibility Criteria
You may qualify if:
- Early rheumatoid arthritis (RA), defined as symptoms of RA that started ≤ 12 months prior to screening and satisfied the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) 2010 criteria for the classification of RA at some point during the 12-month period
- Naïve to any targeted (biologic or nonbiologic) disease-modifying antirheumatic drugs (DMARDs), conventional synthetic DMARDs other than methotrexate (MTX), or investigational therapies for RA
- Treated with MTX for at least 12 weeks, with a stable dose of oral or parenteral MTX for at least 4 weeks prior to randomization
- Anti-cyclic citrullinated peptide-2 (Anti-CCP-2) test that is \> 3× the upper limit of normal and are positive for rheumatoid factor (RF) according to central lab testing during screening
- At least a Disease Activity Score 28-joint count calculated using C-reactive protein (DAS28-CRP) ≥ 3.2 at screening
- At least 3 tender and at least 3 swollen joints at screening and at randomization
You may not qualify if:
- Women who are breastfeeding
- Autoimmune disease other than RA (e.g., psoriasis, systemic lupus erythematosus \[SLE\], vasculitis, seronegative spondyloarthritis, inflammatory bowel disease, Sjogren's syndrome) or currently active fibromyalgia
- History of or current inflammatory joint disease other than RA (e.g., psoriatic arthritis, gout, reactive arthritis, Lyme disease)
- At risk for tuberculosis
- Recent acute infection
- History of chronic or recurrent bacterial infection (e.g., chronic pyelonephritis, osteomyelitis, bronchiectasis)
- History of infection of a joint prosthesis or artificial joint
- History of systemic fungal infections (such as histoplasmosis, blastomycosis, or coccidiomycosis)
- History of primary immunodeficiency
- Current clinical findings or a history of a demyelinating disorder
- or more joints cannot be assessed for tenderness or swelling
