Biomarkers of Anti-TNF-α Therapy Efficacy in Rheumatoid Arthritis to Define Unresponsive Patients (BATTER-UP)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The primary objective of this study was to validate the ability of an 8-gene biomarker set to differentiate between participants who met or did not meet European League Against Rheumatism (EULAR) Disease Activity Score (DAS)-28 Good Response criteria after treatment with anti-Tumor Necrosis Factor (TNF) therapy for 14 weeks in approximately 200 anti-TNF-naïve participants. The secondary objectives of this study was (i) to compare the behavior of the 8-gene marker set in participants who were anti-TNF naïve versus those who began their second anti-TNF treatment , (ii) to develop, maintain, and utilize a biorepository of serum, plasma, RNA, and deoxyribonucleic acid (DNA) samples for additional experiments and analyses and (iii) to discover novel genetic (DNA) predictors of response to anti-TNF therapy.

Ages Eligible for Study:
18 Years and older (Adult, Older Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Participants who meet American College of Rheumatology (ACR) criteria for rheumatoid arthritis (RA) and who, in the opinion of their treating rheumatologist, are not adequately treated with existing therapy and should begin treatment with either an anti TNF agent for the first time or with a different anti-TNF agent.
Key Inclusion Criteria
To be eligible to participate in this study, candidates must meet the following eligibility criteria at the time of enrollment:
Are willing and able to provide informed consent..
Meet the ACR criteria for RA as determined by a rheumatologist who is board certified in Rheumatology or a member of the ACR.
Have 4 or more tender and 4 or more swollen joints out of 28 joints as assessed by their treating rheumatologist or a trained joint assessor.
Subjects are not taking any of the following treatments and/or have washed out for the minimum duration as defined below. If subjects are currently taking these treatments, must have been on a stable dosing regimen for the minimum duration as defined below:
Oral DMARDs (MTX, hydroxychloroquine, sulfasalazine, leflunomide, cyclosporine, azathioprine): on drug for at least 3 months and washed out or stable for at least 6 weeks prior to baseline sample collection.
Oral corticosteroids: washed out or stable AND ≤10 mg/day of prednisone equivalent for at least 4 weeks prior to baseline sample collection.
Intraarticular or parenteral corticosteroids: Washed out or stable for at least 4 weeks prior to baseline sample collection.
NSAIDs: Washed out or stable for at least 2 weeks prior to baseline sample collection.
Are about to start treatment with an anti-TNF agent approved for the treatment of RA for the first time OR Have not, in the opinion of the treating rheumatologist, achieved or maintained an adequate response to treatment with their first anti-TNF agent (any anti-TNF agent approved for the treatment of RA), and have been prescribed a different anti TNF agent. Subjects who switch for any reason other than lack of efficacy will be excluded.
Key Exclusion Criteria
Candidates will be excluded from study entry if any of the following exclusion criteria exist at the time of enrollment:
Any medical condition that would preclude safe use of an anti-TNF agent for at least 14 weeks.
Previous participation in the present study as a subject in the anti-TNF-naïve group.
Prior exposure to 2 or more anti-TNF agents.
Prior exposure to Orencia (abatacept, or CTLA4-Ig) and/or Rituxan (anti CD20), or other biologic therapy for RA or other diseases.
Note: Other protocol defined inclusion/exclusion criteria may apply.
