Background and study aims
Psoriatic arthritis (PsA) is a type of arthris that usually develops in people with the skin condition psoriasis (a skin condition that causes red, flaky, crusty patches of skin covered with silvery scales). PsA causes painful inflammation (swelling) and stiffness in the joints. In PsA, like in psoriasis alone, it is thought to be caused by the immune system mistakenly attacking healthy tissue (autoimmune disease). This study is being carried out to investigate the effects of a drug called secukinumab on patients with psoriatic arthritis. Secukinumab is medication which works by reducing the effects of chemical substances in the body that lead to inflammation (immunosuppressant). This will be done by investigating the effects on components of the blood, including white blood cells (which fight infection), vitamin D and cytokines (small proteins that help cells communicate with each other) in people with PsA and on the blood of healthy participants.
Who can participate?
Adults with PsA who have not previously had biologic therapy and healthy adults who are employed at University of Liverpool or Aintree University hospitals.
What does the study involve?
Eligible patients are registered into the study and receive four injections just below the skin (subcutaneous injections) of 150 - 300 mg subcutaneous injections at weekly intervals, followed by regular injections of 150mg once a month for a total of 12 months, as well as standard treatment with normal disease-modifying antirheumatic drugs (DMARDs, a group of drugs used to treat arthritis by reducing inflammation and reducing damage to the joints). At the start of the study, and then after 3, 6, 9 and 12 months, participants have a sample of blood taken so that white blood cell, vitamin D and cytokine concentrations can be measured. The healthy participants provide a sample of blood at the same time points which is then tested for neutrophil (a type of white blood cell which help fight infection by ingesting microorganisms and releasing enzymes that kill the microorganisms) levels, which are then compared to the results of the participants with PsA.
What are the possible benefits and risks of participating?
There are no direct benefits involved with participating in this study. There is a small risk of pain, bruising or infection when blood samples are taken.

| Scientific title | SATURN: An exploration of the dynamic interaction between IL-17, IL-17 inhibition with (secukinumab) and neutrophils in psoriatic arthritis in vitro and ex vivo with exploratory study on the potential role of Vitamin D |
| Study acronym | SATURN |
| Study objectives | The aim of this study is to investigate, in detail, the clinical and molecular effects of IL-17 and inhibition of IL-17 with secukinumab, on neutrophil function in vitro and ex vivo. In addition, the secondary and exploratory aims are to explore the potential relationship between vitamin D on neutrophil function and response to IL-17 inhibition in psoriatic arthritis. |

| Health condition(s) or problem(s) studied | Specialty: Musculoskeletal disorders, Primary sub-specialty: Inflammatory arthritis; UKCRC code/ Disease: Musculoskeletal/ Other disorders of the musculoskeletal system and connective tissue |
| Intervention | Interventions as of 23/05/2017: Eligible patients with PsA are registered into the study. Participants are treated with Secukinumab and receive four 150 - 300 mg subcutaneous injections at weekly intervals, followed by regular injections 150mg once a month thereafter for a total of 12 months, in addition to standard disease-modifying anti-rheumatic drugs (DMARD) therapy Participants are followed up a 3, 6, 9 and 12 months post treatment. The healthy controls will be recruited from staff at the University of Liverpool or Aintree University hospitals and who are not taking nor have taken over the preceding 6 months, any immunosuppressive agent including systemic corticosteroids and whose health is otherwise good. There will be an equal balance of males to females. The healthy controls will provide one sample of blood for neutrophil studies (in vitro work). The effects of adding exogenous IL-17 and of inhibiting this cytokine by secukinumab, on highly-purified neutrophils isolated from the blood of 10 healthy controls, will be determined. Neutrophil survival will be recorded together with full details on priming of respiratory burst, expression of integrins and other opsono-receptors, apoptosis, phagocytosis and chemotaxis. Experiments will be repeated after neutrophil preparations have been “spiked” with contaminating PBMC’s. If these experiments indicate that the effects of IL-17 on neutrophils are indirect, we will determine the mechanism of PBMC activation. For example, this will include measurement of IL-17 derived neutrophil activating cytokines (by ELISA or multiplex) and/or using blocking monoclonal antibodies. Original interventions: Patients with PsA are allocated to intervention and control arms in a 4:1 ratio by means of computer generated random permuted blocks of size 5. No stratification factors are included. Control arm: Participants receive standard disease-modifying anti-rheumatic drugs (DMARD) therapy. This includes Methotrexate (5mg-25mg orally or subcutaniously) once a week, Sulphasalazine (500mg-1g orally) twice a day and Leflunomide (10mg-20mg orally) once a day for 12 months. Intervention arm: Participants are treated with Secukinumab and receive four 150 - 300 mg subcutaneous injections at weekly intervals, followed by regular injections 150mg once a month thereafter for a total of 12 months, in addition to standard DMARD therapy (as above). Participants in both groups are followed up a 3, 6, 9 and 12 months post treatment. The healthy controls will be recruited from staff at the University of Liverpool or Aintree University hospitals and who are not taking nor have taken over the preceding 6 months, any immunosuppressive agent including systemic corticosteroids and whose health is otherwise good. There will be an equal balance of males to females. The healthy controls will provide one sample of blood for neutrophil studies (in vitro work). The effects of adding exogenous IL-17 and of inhibiting this cytokine by secukinumab, on highly-purified neutrophils isolated from the blood of 10 healthy controls, will be determined. Neutrophil survival will be recorded together with full details on priming of respiratory burst, expression of integrins and other opsono-receptors, apoptosis, phagocytosis and chemotaxis.
