- Healt Condition(s) or Problem(s) studiedRheumatoid arthritis
- Inclusion criteria1. Patients aged ≥18 years;
2. Diagnosis of RA according to ACR criteria;
3. Active RA (Disease Activity Score 28 >3.2);
4. Treatment with disease modifying anti-rheumatic drugs (DMARDS), biologicals and in addition, corticosteroids up to 10 mg daily and non-steroidal anti-inflammatory drugs (NSAIDs) is permitted, provided that there is a stable dose for at least 2 weeks;
5. All acute toxic effects of any prior therapy returned to classification mild according to MedDRA;
6. Sufficient hematologic, liver and renal function: total white cell count as well as ANC should be normal prior to start of the treatment, as well as liver function tests:
A. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L, platelets ≥ 100 x 109/L, haemoglobin (Hb) ≥ 9.5 g/dL;

9. Evidence of a personally signed and dated Ethics Committee-approved Informed Consent form indicating that the patient (or legally acceptable representative) has been informed of all pertinent aspects of the study;
10. Willingness and ability to comply with the scheduled visits, treatment plan, laboratory tests and other study procedures.
- Exclusion criteria1. Presence of active infections (e.g. requiring antibiotic therapy) or other severe concurrent disease, which, in the opinion of the investigator, would place the patient at undue risk or interfere with the study;

3. Known primary or secondary immunodeficiency;
4. HIV positive patient;
5. Evidence of active malignant disease, malignancies diagnosed within the previous 5 years;

- Brief summaryBackground:
Rheumatoid arthritis (RA) is a chronic inflammatory and destructive joint disease. Therapy of RA include NSAIDs, Disease modifying drugs (DMARDs) and biological compounds that target TNF-α and other inflammatory cytokines, B-cells or T-cells. However a substantial part of patients do not respond to these treatments or had to stop treatment due to drug-related adverse events, resulting in an unmet need for alternative therapies.
Interleukin-10 (IL-10) is a cytokine produced by activated monocytes and T cells which is deeply involved in the regulation of inflammatory responses and immune reactions. IL-10 has been considered an attractive candidate for therapeutic use based on its potent in vitro immunomodulating activities and proven effects in animal models of acute and chronic inflammation, autoimmunitiy, cancer and infectious disease.
In the F8IL10 molecule, IL-10 is coupled to the antibody fragment F8 which binds to the extra-domain A of fibronectin, selectively expressed at sites of inflammation. Upon administration to a patient, F8IL10 is supposed to accumulate at the site of arthritis and exhibit its biological function there.

Study objectives:
1. Evaluation of the targeting performance of the human radiolabeled monoclonal-antibody cytokine fusion protein 124I-F8IL10 in 5 patients with RA;
2. Determine dosimetric parameters.

Patients and methods:
Patients: 5 patients with active RA.
Methods: intravenous infusion of 74MBq 124I-F8IL10 followed by PET-CT scanning at 0.5-1, 24 and 74h, including blood sampling for determination of pharmacokinetics.
