Plain English Summary

Background and study aims
Psoriatic arthritis (PsA) is a type of arthritis that affects some people with the skin condition psoriasis. It typically causes affected joints to become swollen, stiff and painful.
PsA is an inflammatory arthritis that develops in around 15% of people with psoriasis, causing swollen and painful joints. For patients who do not respond to standard arthritis drugs, two classes of biologic drugs are available (TNF or IL-17 blockers). A similar proportion of patients respond to both with around 50% achieving a good response. However, we do not know how to predict which patient will respond best to each drug.
Our aim is to test whether we can predict if people with psoriatic arthritis (PsA) will respond to certain biologic drugs using blood tests. We will test if high levels of a type of T cells (activated Th17 cells) or other laboratory tests predict response. We will use statistical tests to estimate how effective these approaches would be for each individual. If successful, this approach could ensure that patients receive their best option first, ensuring their disease is controlled and quality of life improved, while avoiding unnecessary drug use. This is likely to save money for the NHS.

Who can participate?
Patients aged 18 years or older, with PsA about to start their first biologic treatment will be invited to join the study.

What does the study involve?
Participants will have a blood sample taken to measure their activated Th17 cells. The patients will be allocated to receive either TNF or IL-17 blocking biologics. We will measure how well they respond after 6 months of treatment and test whether the initial blood test result could have predicted their response.

What are the possible benefits and risks of participating?
Participants are not expected to benefit directly from participating in the study however they should see an improvement in their PsA symptoms from the treatment they receive. Study visits have been aligned with routine NHS visits to minimise burden and inconvenience but will take longer and participants will be asked to complete extra questionnaires. Participants will need to have additional blood samples taken which may result in bruising but research samples will be taken at the same time as routine NHS blood tests wherever possible.
Participants at 3 sites (Oxford, Glasgow, & St Guys & St Thomas's) will be asked to attend a short additional visit to enable the collection of an additional blood sample. Travel costs will be reimbursed for this additional visit to minimise any financial burden.
There are no additional risks from the treatment as the study uses the same treatments that would be prescribed routinely for these patients.

Where is the study run from?
University of Oxford (UK)

When is the study starting and how long is it expected to run for?
February 2021 to September 2026

Study hypothesisA precision choice of bDMARDs in PsA based on lymphocyte cell surface markers guiding selection of either TNF inhibitor or IL17A inhibitor will give superior results to patients having a choice of bDMARD based on clinical characteristics alone.
Ethics approval(s)Approved 24/02/2021, North West - Preston REC (Barlow House, 3rd Floor, 4 Minshull Street, Manchester, M1 3DZ, UK; +44 (0)207 104 8206; Preston.rec@hra.nhs.uk), ref: 21/NW/0016
ConditionArthritis that affects some people with the skin condition psoriasis
InterventionAll patients will be treated with a biologic drug (TNF inhibitors (adalimumab) or IL-17A inhibitors (secukinumab) in keeping with routine clinical practice. At present both TNF inhibitors and IL-17 inhibitors are licensed and NICE approved as first line biologics in PsA. Patients will be randomised in a 1:1 ratio to receive either TNF or IL-17A inhibitors, stratified by baseline immunophenotype, for 24 weeks.

The TNF inhibitor to be used is adalimumab (any brand) and it is to be given at the usual licensed dose, as per the SmPC:
-The licenced dose of adalimumab for psoriatic arthritis is always 40 mg by subcutaneous injection every 2 weeks, with no loading doses.

The IL-17A inhibitor to be used is secukinumab, brand name Cosentyx, and is to be given at the usual licensed dose as per the SmPC:
-The licensed dose of secukinumab for psoriatic arthritis varies based on the level of baseline skin psoriasis. For patients with concomitant moderate to severe plaque psoriasis, the recommended dose is 300mg by subcutaneous injection with initial dosing at weeks 0, 1, 2, 3 and 4 followed by a monthly maintenance dose. For other patients the recommended dose is 150mg by subcutaneous injection at the same timepoints. This study will follow routine practice and the current label by using the appropriate dose of secukinumab based on the baseline psoriasis disease activity with the cut off for moderate to severe psoriasis as 10% body surface area. Dose escalation as per the licence is permitted.
