Plain English Summary

Background and study aims
Patients newly diagnosed with Rheumatoid Arthritis (autoimmune disease that causes inflammation in your joints) are treated conventionally according to National Institute for Health and Clinical Excellence (NICE) guidelines. There is no cure for Rheumatoid arthritis (RA), instead, the goal is to achieve low disease activity and ultimately disease remission. It is not currently possible to predict which drug (or drugs) will produce a favourable response in a particular patient and it is currently difficult to identify patients in clinical remission. This study aims to define predictors of clinical response and define what true remission is in patients with early RA. The plan is to use this information to develop an 'immunological toolkit' to help predict which patients will respond well to particular treatments so that patients can be treated with individualised drug combinations that are most likely to induce and sustain remission.

Who can participate?
The study will recruit 410 participants over the age of 18 within 4 weeks of diagnosis with Rheumatoid Arthritis. They will not have received disease-modifying antirheumatic drugs (DMARDs) or corticosteroid treatment for the current episode of inflammatory arthritis. In addition all subjects will be positive for Rheumatoid Factor and Anti-citrullinated protein antibody (ACPA).

What does the study involve?
Patients will receive standard treatment following national guidelines throughout the study period. The study duration will be 18 months. Patients will be assessed at months 0, 3, 6, 9, 12, 15 and 18 using standard validated questionnaires and blood tests as set out in current guidelines. Biological sampling (blood and urine) will be carried out at each assessment for the purpose of developing an 'immunological toolkit'. X-rays will be taken at 0, 12 and 18 months.

What are the possible benefits and risks of participating?
Although not of direct benefit to participants in the study, it is hoped that the information we get from this study will help improve the treatment of people with rheumatoid arthritis in the future.
As this is an observational study there are no additional risks relating to taking medication involved beyond those which you would experience in routine care. However, there is a modest risk of side effects including pain, bruising, light headedness, and, on rare occasions, infection that could arise as a consequence of having blood taken. To minimise this risk, blood will be taken by a clinical professional trained and experienced in taking blood from patients. In all we will need to take seven lots of blood samples from you, in total about 1.5 - 3 egg cups of blood on each occasion, during this study.

Where is the study run from?
The study is being managed by King's College London. Between 26 and 40 recruitment sites will be set up across England and Scotland.

When is the study starting and how long is it expected to run for?
It is anticipated that recruitment will start Sept/Oct 2012 with the study ending after four years.

Who is funding the study?
The study is funded as part of a programme grant from the Medical Research Council (MRC).

Scientific titleThe TACERA Study: a longitudinal observational study of patients with early rheumatoid arthritis
Study acronymTACERA
Study hypothesisOur working hypothesis is that a suite of immunological assays (hereafter termed 'the immunological toolkit') can be used to accurately predict clinical responses to therapy at a molecular and cellular level. We also propose that immune-based assays can be adapted to define an immune signature associated with a state of sustained clinical remission in patients with early RA. This study protocol seeks to recruit a large cohort of patients with early RA. Biological samples will be acquired from study subjects and used to develop the immunological toolkit, through the identification of baseline biomarker signatures (prior to starting therapy), and by documenting the changes in the immune system in response to therapeutic intervention.

Several principles underpin this study:
1. RA is associated with detectable perturbations of the immune system at very early stages of disease.
2. Clinical remission is associated with a biological state that has similarities to a healthy immune system.
3. The healthy immune system is associated with a distinct immunological fingerprint defined by serum, cellular and/or molecular signatures in peripheral blood.
4. Restoration of this state of immune health may be induced with therapies that target these perturbations.

InterventionThe study is observational, meaning that we are just looking at how arthritis responds to standard therapy in patients, rather than testing the effects of new treatments. Patients who have been diagnosed with early RA, within 6 months of symptom onset, will receive treatment according to NICE guidelines. Patients will participate in the study for 18 months, attending assessments every 3 months. During these visits a detailed assessment of disease activity (including standard blood monitoring for DMARDs and TNF-inhibitors) will take place along with completion of a number of questionnaires and the provision of additional blood and urine samples for immunoanalysis.

At each study assessment the following will take place:

Patients will complete the following with the research nurse:
1. Disease Activity Score (DAS28 & extended swollen and tender joint counts 66/68, patient global assessment)
2. HAQ (Health assessment questionnaire measuring disability)
3. Lifestyle Factors Questionnaire

The following questionnaires will be completed at Baseline, 6, 12 and 18 months only:
1. SF36 (Quality of life questionnaire)
2. EQ5D (Health outcome questionnaire)
3. FACIT-F questionnaire (Functional assessment of Chronic Illness Therapy)
4. IPQ-R-RA (Illness Perception Questionnaire)
5. MAPLe-RA (Measuring Actual Patient-Led expectations)

The following will be reviewed:
1. Concomitant Diseases and medication
2. Current Medication
3. Adverse events

The following samples will be taken:
1. Blood samples for routine safety monitoring and ESR and CRP values
2. Blood and urine samples for the immunoanalysis.

X-rays of hands and feet will be taken at Baseline, 12 and 18 months.

HRUS (High Resolution Ultrasonography) will be undertaken at baseline, 6 and 12 months (an 18 month scan will be optional). This ultasound based imaging is optional and will be offered to patients at those recruiting centres that provide this service as part of routine clinical care.

Patients may also be telephoned by their Research Nurse in between study visits to check how well their disease is being controlled by their medication.

Primary outcome measureCurrent primary outcome measures as of 10/06/2015:
Disease remission at 6 months will be the primary outcome and this will be measured using either the long established DAS28 criterion (DAS28 score <2.6) or the Simplified Disease Activity Index (SDAI) ≤ 3.3, or the new ACR/EULAR 2010 remission criteria:
1. Swollen joint count ≤1
2. Tender joint count ≤ 1
3. CRP ≤ 1 (mg/dl)
4. Patient global ≤ 1 (on a 1 to 10 scale)

3. CRP ≤ 1 (mg/dl)
4. Patient global ≤ 1 (on a 1 to 10 scale)
