Plain English Summary

Background and study aims
Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by persistent synovitis (joint inflammation), systemic inflammation, and autoantibodies, particularly rheumatoid factor and citrullinated peptide. These autoantibodies are thought to play critical roles in initiating inflammatory responses in RA. In industrialized countries, RA affects 0.5-1% of adults, with 5-50 per 100,000 new cases annually.
Despite the clinical and radiological benefits of biological therapies, many patients fail to achieve low disease activity or remission. Almost 40% of all patients treated with biologic disease-modifying anti-rheumatic drugs (b-DMARDs) do not experience minimally acceptable improvement. Thus, treating RA patients according to their biomarker profiles would provide better care, prevent unnecessary exposure to potentially toxic drugs, and be cost-saving.
We aim to test whether RNA signatures (biomarkers) in the tissue surrounding the joints (synovial tissue) from patients with early RA are predictive of response to abatacept, a biologic disease-modifying anti-rheumatic drug (b-DMARD).

Who can participate?
Adults with early RA (symptoms for less than 12 months) who have not previously been treated with DMARD therapies.

What does the study involve?
Participants will undergo a synovial biopsy of their joint to collect tissue samples for RNA analysis. Patients will then be randomly assigned to receive either abatacept and methotrexate or placebo and methotrexate. The randomisation will be based on biomarker profiles. Patients will attend study visits every 4 weeks for up to 16 weeks, followed by a 30-day safety follow-up visit.

What are the possible benefits and risks of participating?
Participants may experience an improvement in their arthritis symptoms, although there may be no direct benefit. However, the trial will generate essential information that could benefit future RA patients. Abatacept has evidence supporting its effectiveness in patients where conventional DMARDs have failed. This study aims to determine whether specific RNA signatures can accurately predict the best treatment for early RA patients.
Injection site reactions with abatacept and the risk of infections will be discussed with the patient before enrollment in the study. Participants would be at no greater risk than routine care within the NHS.
An ultrasound-guided synovial biopsy is a quick, safe, and well-tolerated procedure. Patients who consent to the study and the biopsy will have a longer hospital appointment and may experience discomfort from the local anaesthetic and biopsy procedure. However, published data confirm that this procedure is well-tolerated and safe, and patients are generally agreeable to multiple biopsies

Scientific titleThe 3TR Molecular PAthobiology and PRecision Therapy iN EaRly Rheumatoid Arthritis Study (3TR-PARTNER-RA)
Study acronym3TR-PARTNER-RA
Study hypothesisThe primary objective of this trial is to determine whether synovial molecular profiles can inform treatment response to abatacept in early RA.
To this aim, we will compare the change in Clinical Disease Activity Index (CDAI) score at 16 weeks between the biomarker positive and the biomarker negative patients within the abatacept group (i.e. Group 1 vs Group 3).
We hypothesise that patients with high synovial immunological infiltrate (lymphoid pathotype) will respond better to abatacept therapy.

Secondary objective:
We aim to assess patients treated according to their biomarker: comparing the biomarker-positive patients (as Groups 1 minus 2) vs the biomarker-negative patients (as Groups 3 minus 4).

Participant inclusion criteria1. Adults (female and male) aged 18 years or over.
2. Willing and capable of giving informed consent.
3. 2010 ACR / EULAR classification criteria for a diagnosis of Rheumatoid Arthritis. *
4. Symptom duration of <12 months
5. At least one swollen joint, which is amenable to synovial biopsy (minimum grade 2 synovial thickening, as assessed at the biopsy visit).
6. Moderate and severe Disease Activity (DAS28>3.2)
7. No prior DMARD therapies (conventional, targeted or biologic DMARDs)
8. Patient is judged by the supervising clinician to be a suitable candidate based upon medical history, physical examination, vital signs, and routine laboratory tests.
9. Willing and able to comply with scheduled visits, laboratory tests, and other study procedures.
* The ACR/EULAR classification for a diagnosis of RA could have been at any time in the patient’s disease history; the score does not need to be 6 or more at screening.
Participant exclusion criteria1. Patients unable to tolerate synovial biopsy or in whom this is contraindicated including patients on anti-coagulants (e.g. warfarin). Patients on short-acting direct oral anticoagulant agents can be considered when anti-coagulant can be temporarily stopped, in line with local guidelines for procedures with a low risk of bleeding, taking into account the individual thromboembolic risk. Oral anti-platelet agents are permitted.
2. Patients in whom there is no suitable joint for biopsy.
3. Hypersensitivity to the active substance or to any of the excipients of abatacept or methotrexate, or any other contraindications to the study medications, as per the current SmPC.
4. History of or current primary inflammatory joint disease or primary rheumatological autoimmune disease other than RA (if secondary to RA, then the patient is still eligible).
5. Prior exposure to any biologic/targeted DMARDs for RA
6. Treatment with any investigational agent ≤ 8 weeks prior to baseline or < 5 half-lives of the investigational drug (whichever is the longer)
7. Intra-articular or parenteral corticosteroids, or oral prednisolone more than 10mg/d or equivalent ≤ 4 weeks prior to screening visit.
8. Patients with a serious underlying medical disorder (e.g., end stage renal disease).
9. Active infection
10. Subject has a history or known presence of recurrent or chronic infection (eg, hepatitis B virus [HBV], hepatitis C virus [HCV], human immunodeficiency virus HIV]; recurrent urinary tract infections are allowed.
11. Subjects testing positive for acute or chronic hepatitis A, B, or C, unless they are indicative of prior hepatitis B vaccination or cured hepatitis A or B and accompanied by normal liver transaminase values.
12. Septic arthritis of a native joint within the last 12 months
13. Septic arthritis of a prosthetic joint within 12 months or indefinitely if the joint remains in situ
14. Latent TB infection unless they have completed adequate antibiotic prophylaxis

18. Known recent substance abuse (drug or alcohol).
19. Patients currently recruited to other clinical trials or taking part in a CTIMP study in the previous 4 months.
20. Other severe acute or chronic medical or psychiatric condition, or laboratory abnormality that would impart, in the judgment of the investigator, excess risk associated with study participation or study drug administration, or which, in the judgment of the investigator, would make the patient inappropriate for entry into this study. This should include assessment of risk factors for known clinically important risks associated with a study drug.
21. Patients with severe hepatic impairment (Child Pugh C classification).
22. Patients that are primary or secondary immunodeficiency (history of or currently active).
23. Poor tolerability of venepuncture or lack of adequate venous access for required blood sampling during the study period.
