About this study
Official title: Outcomes With Treatment and Withdraw of Secukinumab in Patients With Plaque Psoriasis Compared to Standard Care --- a Pragmatic Observational Study
Psoriasis (PsO) is a systemic immune disease that affect 2-4% of the population worldwide. PsO causes tremendous burden in terms of quality of life, psychological impact, disability and work productivity of affected individuals. PsO is associated with an increased risk of cardiovascular morbidities and mortality in the long term. Up to 30% of PsO patients develop psoriatic arthritis (PsA) over time causing joint deformities and further disabilities. Majority of patients with PsA developed PsO first, and arthritis develop 5-10 years after. PsA and PsO are increasingly recognized as two entities under the umbrella of psoriatic diseases.
Advances in biological treatments have greatly improved the prognosis of patients with PsO. Remarkable efficacies have been demonstrated for patients with moderate to severe PsO in randomized controlled trials (RCTs). However, the high cost of biological treatment is one of the major barriers to its prescription and many patients may have limited access to these treatments.

The best treatment strategy for PsO that takes into account efficacy and cost effectiveness is unknown. For instance, whether some PsO patients can stop biological treatment and be treated with non-biologic medications upon relapse, which may enhance cost effectiveness of treatment. Preliminary studies have shown that some PsO patients were able to maintain good control of disease without medications after biologics withdrawal. The patho-immunological mechanisms behind long term remission after drug withdrawal is poorly understood. Better understanding of these mechanisms in maintaining remission and relapses will advance the development of biomarkers that eventually guide development of best treatment strategies for PsO.
Secukinumab targets interleukin (IL)-17a and is highly efficacious in the treatment of plague PsO with a favorable safety profile. Some patients may have the response maintained after withdrawal of secukinumab. With the proven efficacies, sustainability after withdrawal and safety profile, secukinumab could be a choice of initial treatment for patients with moderate to severe PsO. Secukinumab has been recommended as first line treatment for selected patients with moderate to severe PsO by the American Academy of Dermatology and the European S3 guidelines. However, the use of biologics as first line is limited by cost issue. Overall, real-life data on biologic treatment for moderate to severe PsO is scanty.
Read the detailed description
First, the investigators hypothesize that a proportion of participants with moderate to severe PsO may sustain good outcomes when a short course of secukinumab is withdrawn.
Second, the investigators hypothesize that they can identify the perturbations in the architecture of the immunome which are pathogenic, and to discriminate such perturbations based on treatment and clinical responses, thus distilling therapeutics and diagnostics signatures.
Therefore, the objectives of this study are as follow:
Specific aim 1: To describe the clinical course, sustained good outcomes, relapse rate, time to relapse and quality of life in PsO participants who stopped a 6-month short course treatment of secukinumab, till the end of 2-years.
Specific aim 2: To identify the genomic and immunomics signatures in skin biopsies and blood in PsO participants who has good outcomes (PASI 75) at 6 months, comparing treatment vs pragmatic control.
Specific aim 3: To identify the genomic and immunomics signatures in skin biopsies and blood in PsO participants who sustained good outcomes at 1 year after stopping secukinumab, compared to those relapsed.

Quality of life 1 (EuroQoL-5D-5L)
In all participants (both secukinumab treated and standard care) the investigators will describe the following:
Every 3-6 monthly till end of 30 months, investigators will evaluate the change scores of Quality of Life (EQ5D-5L). It consists of the EQ-5D-5L descriptive system and the EQ visual analogue scale (EQ VAS). The descriptive system comprises five dimensions. Each dimension is measured on a scale of 1-5, with '1' indicating no problem, '2' indicating slight problems, '3' indicating moderate problems, '4' indicating severe problems, and '5' indicating unable to/extreme problems. The highest and the lowest scores for both EQ-5D-5L indices were 1.00 (best imaginable health) and -0.769 respectively; where negative values are valued as worse than dead.
EQ VAS records the patient's self-rated health on a vertical visual analogue scale from 0-100 with '0' indicating worst health one can imagine and '100' indicating best health one can imagine.
Measured: 3, 6, 9, 12, 15, 18, 24 and 30 months

DLQI is measured on a scale of 0-3 or not relevant, with '0' indicating not relevant or not at all, '1' indicating a little, '2' indicating a lot, '3' indicating very much. The final score ranges from 0 (minimal effect on quality of life) to 30 (maximum effect on quality of life).

The investigators will evaluate the change scores of Hospital Anxiety and Depression Scale (HADS) at various time points from baseline. HADS is a 14 item scale with 7 of the items related to anxiety and the other 7 related to depression. Each item on the questionnaire is scored from 0-3, resulting in anxiety and depression scores each of 0 (no anxiety/depression) to 21 (severe anxiety/depression).
Measured: 3, 6, 9, 12, 15, 18, 24 and 30 months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing secukinumab, Methotrexate and Cyclosporin A in people with Plaque Psoriasis, run by Singapore General Hospital at 1 site in Singapore.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 25 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ying Ying Leung, MD (+65 63265276, katy.leung.y.y@singhealth.com.sg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of secukinumab treated PsO participants free of relapse after secukinumab withdrawal (time frame: 12 months from secukinumab withdrawal or 18 months from baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Nov 2022; AzTrials last refreshed its copy on 8 Nov 2026.
