| Scientific title | Prospective randomised study assessing the efficacy of Tocilizumab with synovial analysis in patients with rheumatoid arthritis |
| Study acronym | TOCRA |
| Study objectives | Aim: To study the mode of action of tocilizumab in patients with active rheumatoid arthritis (RA) who have failed to respond to at least one tumour necrotising factor (TNF) antagonist, or are not candidates for such treatment. |
| Ethics approval(s) | Leeds West Research Ethics Committee (REC) approved on the 27th February 2009 (ref: 08/H1307/119) |
| Health condition(s) or problem(s) studied | Topic: Musculoskeletal; Subtopic: Musculoskeletal (all Subtopics); Disease: Musculoskeletal |
| Intervention | 1. Tocilizumab intravenous (IV), 4-weekly for 48 weeks 2. Placebo IV, 4-weekly for 12 weeks Then all patient receive tocilizumab/methotrexate, 2.5 mg or 10 mg tablets/7.5 - 10 mg syringe. Weekly dose up to 25 mg. Total duration of treatment and follow-up: 56 weeks |
| Intervention type | Drug |
| Pharmaceutical study type(s) | |
| Phase | Phase III |
| Drug / device / biological / vaccine name(s) | Tocilizumab, methotrexate |
| Primary outcome measure | Changes in synovial tissue to identify onset and mechanism of action |
| Secondary outcome measures | 1. To evaluate the safety of tocilizumab and methotrexate combination for the treatment of rheumatoid arthritis by assessment of: 1.1. Incidence, frequency of adverse events 1.2. Vital signs 1.3. Blood haematology, chemistry, urinalysis 1.4. Electrocardiogram (ECG) 2.

MRI features (bone oedema and erosion score) in addition to synovial volume (primary outcome) 2.2.2. Ultrasonographical features (grey scale, power doppler and erosions) 2.2.3. Plain radiography 2.2.4. Bone densitometry 2.3. Synovial assessment: 2.3.1. Macroscopic synovitis and vascularity scores 2.3.2. Histological score and pro-inflammatory cytokine expression in biopsies 3. To evaluate predictive and mechanistic features of tocilizumab and methotrexate/disease-modifying anti-rheumatic drug (DMARD) combination by: 3.1. Biomarker, cell biology and genetics studies: 3.1.1. Predictive markers of response to tocilizumab 3.1.2. Mechanistic studies 3.1.3. Genetic studies to evaluate mechanism and response to tocilizumab |

Eligibility
| Participant type(s) | Patient |
|---|---|
| Age group | Not Specified |
| Sex | Both |

| Key inclusion criteria | Subjects meeting all of the following criteria will be considered for enrolment into the study: 1. Male and female patients aged between 18 and 80 years 2. Diagnosis of rheumatoid arthritis (1987 revised American College of Rheumatology [ACR] criteria) confirmed at least 6 months prior to screening 3. Persistent RA disease activity with inadequate response whilst being treated with an anti-TNF agent for at least 12 weeks, or patients who have previously discontinued anti-TNF due to toxicity, or patients have previously qualified for anti-TNF (NICE/BSR criteria) but therapy is contra-indicated 4. Methotrexate dose stable for 12 weeks prior to screening and to be continued for the duration of the study 5. Subjects with active RA at baseline are defined as: Disease Activity Scale (DAS28) greater than 5.1 6. Patients on non-steroidal anti-inflammatory drugs (NSAIDs) and/or corticosteroids must have remained on an unchanged regimen for at least 28 days prior to study drug administration 7. Patients must be able and willing to comply with the terms of this protocol including attending for arthroscopy and imaging assessments 8. Informed consent must be obtained in writing for all subjects at enrolment into the study |
| Key exclusion criteria | Subjects presenting with any of the following will not be included in the study: 1. Patients unwilling or unable to receive methotrexate for the duration of the study 2. Patients with inflammatory joint disease of different origin, mixed connective tissue disease, Reiter's syndrome, psoriatic arthritis, systemic lupus erythematosus, or any arthritis with onset prior to 16 years of age 3. Suspicion of diagnosis of tuberculosis (positive tuberculosis test (greater than 5 mm induration if previous BCG or greater than 10 mm if no previous BCG) or abnormal chest x-ray) 4. Patients with concomitant medical condition which would in the investigator's opinion compromise the patient's ability to tolerate, absorb, metabolise or excrete the study medication 5. Patients with serious infections within 3 month of enrolment (screening) or persistent infections 6. Patients at significant risk of infection (e.g. leg ulceration, indwelling urinary catheter, septic joint within 1 year [or ever if prosthetic joint still in situ]) 7. Patients with malignancy (other than excised basal cell carcinoma) within the last 5 years before study entry (screening) 8. Patients with history of Felty's syndrome, uncontrolled diabetes, uncontrolled hypertension, unstable ischaemic heart disease, active bowel disease, active peptic ulcer disease, recent stroke (within three month before study entry screening), or other condition which, in the opinion of the investigator, would put the patient at risk to participate in the study 9.
