Trial summary

Biologics such as risankizumab are currently the most effective treatment option for patients with moderate to severe psoriasis. But they are costly for healthcare systems and still described according to a 'one dose fits all' dosing regimen, leading to potential over-and undertreatment. Read more about this study

About this study

Official title: Evaluation of the Predictive Value of Early Serum Trough Concentrations and Anti-drug Antibodies of Risankizumab and the Development of a Response-concentration Curve for Risankizumab in Patients With Psoriasis

Biologics such as risankizumab are currently the most effective treatment option for patients with moderate to severe psoriasis. But they are costly for healthcare systems and still described according to a 'one dose fits all' dosing regimen, leading to potential over-and undertreatment. In this study the investigators aim to investigate the predictive value of early serum trough levels of risankizumab and determine the therapeutic window of risankizumab in psoriasis patients.

Read the detailed description

Patients will be included after signing informed consent. After inclusion, patients will continue on standard dosing schedule of risankizumab (i.e. subcutaneous injections at weeks 0 and 4, then every 12 weeks (2x 75mg)). During each study visit blood will be taken in order to quantify Ctroughs and/or anti-drug antibodies towards risankizumab. In addition, Psoriasis Area and Severity Index (PASI) and Investigator's Global Assessment (IGA) score will be evaluated by a physician. Patients complete the Dermatology Life Quality Index (DLQI) and European quality of life EQ-5D instrument at each visit.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • VenapunctureProcedure or surgery

    Blood samples will be collected to determine the serum trough levels and anti-drug antibodies of risankizumab.

  • Patient questionnairesProcedure or surgery

    The study participants will complete the Dermatology Quality of Life (DLQI) and EQ-5D-5L questionnaire at each study visit.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Predictive value of early serum trough concentrations of risankizumab

    To assess the predictive value of early serum trough levels of risankizumab (µg/ml), the clinical response (PASI) at week 12 and/or week 24 will be correlated with serum trough concentrations of tildrakizumab measurements taken from week 0,1,2,3 and/or 4.

    Measured: Week 0 until week 24 of treatment

  2. Predictive value of early anti-drug antibodies of risankizumab

    To assess the predictive value of early anti-drug antibodies of risankizumab (µg/ml), the clinical response (PASI) at week 12 and/or week 24 will be correlated with anti-drug antibodies of tildrakizumab measurements taken from week 0,1,2,3 and/or 4.

    Measured: Week 0 until week 24 of treatment

  3. Development of the therapeutic window of risankizumab in psoriasis

    Defining a therapeutic window for risankizumab based on serum trough concentrations corresponding with adequate clinical response (ROC analysis and concentration-effect curve)

    Measured: Week 0 until week 52 of treatment

Secondary outcomes (3)
  1. DLQI

    The DLQI (Dermatology Life Quality Index) (range 0-30) is a dermatology specific quality of life (QoL) instrument designed to assess the impact of the disease on participant's QoL. It is a ten item questionnaire that, in addition to evaluated overall QoL, can be used to assess six different aspects that may affect QoL: 1) symptoms and feelings, 2) daily activities, 3) leasure, 4) work or school performances, 5) personal relationships, and 6) treatment.

    The scoring of each question is as follows:

    Very much - scored 3; A lot - scored 2; A little - scored 1; Not at all - scored 0; Not relevant - scored 0; Question 7, 'prevented work or studying' - scored 3. The DLQI is calculated by summing the score of each question resulting in a maximum of 30 and a minimum of 0. The higher the score, the more quality of life is impaired.

    Measured: Week 0 until week 52 of treatment

  2. EQ-5D-5L

    The EQ-5D-5L comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems.The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits of the five dimensions can be combined into a 5- digit number that describes the patients' health state.

    Measured: Week 0 until week 52 of treatment

  3. EQ VAS

    The EQ VAS (Visual Analogue Scale) (range 0-10) records the patient's self-rated health on a vertical visual analogue scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The VAS can be used as a quantitative measure of health outcome that reflect the patient's own judgement.

    Measured: Week 0 until week 52 of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Venapuncture and Patient questionnaires in people with Psoriasis Vulgaris, run by University Hospital, Ghent at 7 sites in Belgium.

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 2 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 5 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in Belgium. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Jo Lambert, Prof. (09 332 22 87 ext. +32, jo.lambert@uzgent.be), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Predictive value of early serum trough concentrations of risankizumab (time frame: Week 0 until week 24 of treatment). The study lists 3 primary outcomes in all. 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 5 Feb 2024.
