Preliminary data suggest that up-regulation of Interleukin -17 (IL-17) and the T-helper 17 (Th17) pathway occurs in rheumatoid arthritis (RA) patients on anti-Tumour Necrosis Factor (TNF) therapy who demonstrated an incomplete clinical response. A deeper understanding of this is required in order to determine whether IL-17 or the Th17 pathway is a valid target for intervention in this population to improve response outcome. The study objective is to observe biologic naïve RA subjects on anti-TNF therapies and take measurements of peripheral blood and synovial tissue to assess differences in the IL-17 and Th17 pathways between responders and non-responders. The aim of the study is to test if increased Th17 pathway activity is present in subjects who do not respond clinically to anti-TNF therapy. Clinical assessments, synovial bio-markers and ultrasound will be used as determinants of clinical response. The study may identify disease characteristics that determine which subjects may be more likely to respond to anti-TNF therapy, or those who may require either a different treatment option, or additional pathway inhibition in addition to TNF, in order to achieve clinical response.

Age group | 18 Years and older |
Eligibility | Inclusion Criteria: 1. Men and women = 18 years of age 2. An RA diagnosis as defined by the 2010 revised EULAR/ACR classification criteria. 3. Subjects who fulfil the NICE guidelines for Biologic therapy as their first line treatment following failure of standard disease modifying anti-rheumatic therapy. 4. Subjects may be on cDMARDs (or MTX monotherapy) one of which must be MTX. Participants should be receiving MTX for at least 2 months at a stable dose of 7.5-25 mg/week before Week 0 visit. 5. Subjects may be on oral steroids (prednisone =10 mg/day, or equivalent corticosteroid) with a stable dose for the 4 weeks prior to Week 0 visit. 6. Men and women of childbearing potential must use adequate birth control measures (e.g., abstinence, oral contraceptives, intrauterine device, barrier method with spermicide, or surgical sterilization) for the duration of the study. 7. Participants must be able to adhere to the study visit schedule. 8. The participant must be capable of giving informed consent and the consent must be obtained prior to any screening procedures. 9. Must have a chest X-ray within 6 months prior to commencement of anti-TNF therapy with no evidence of malignancy, infection or fibrosis. Exclusion Criteria: Participants will be excluded from this study for any of the following reasons: 1. Women who are pregnant or breast feeding. 2. Previous use of Rheumatoid Arthritis anti-TNF biologics, or ANY other type of biologic therapy or Investigational Medicinal Product. 3. Treatment with any other therapeutic agent targeted at reducing TNF within 3 months of screening. 4. Serious infections (such as pneumonia or pyelonephritis) in the previous 3 months. Less serious infections (such as acute upper respiratory tract infection [colds] or simple urinary tract infection) need not be considered exclusions at the discretion of the investigator. 5. Known HIV, Hepatitis B, or Hepatitis C infection. 6. Have active TB or have evidence of latent TB (old or latent TB on chest x-ray, without adequate therapy for TB initiated prior to first dose of study drug). Participants with a current close contact with an individual with active TB and participants who have completed treatment for active TB within the previous 2 years are explicitly excluded from the trial. Participants with a household member who has a history of active pulmonary TB should have had a thorough evaluation for TB prior to study enrolment as recommended by a local infectious disease specialist or published local guidelines of TB control agencies. 7. Presence of a transplanted organ (with the exception of a corneal transplant >3 months prior to screening). 8. Malignancy within the past 5 years (except for squamous or basal cell carcinoma of the skin that has been treated with no evidence of recurrence). 9. History of lymphoproliferative disease including lymphoma, or signs and symptoms suggestive of possible lymphoproliferative disease, such as lymphadenopathy of unusual size or location (such as nodes in the posterior triangle of the neck, infra-clavicular, epitrochlear, or periaortic areas), or splenomegaly. 10. Known recent substance abuse (drug or alcohol). 11. Poor tolerability of venepuncture required blood sampling during the study period. 12. Planning to have surgery for RA or other significant surgery during the period of the study. |
