Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years and Over|
- - Plaque psoriasis (primarily) - Treatment for at least 6 months with IL23 or IL17 inhibitor in a normal dose (dose advised by the label) - PASI≤ 5 at inclusion and in previous 6 months (if no PASI scores are available, it should be clear from the patient record that psoriasis was clear/almost clear in previous 6 months).
- - DLQI ≤ 5 at inclusion.
- - Another indication than plaque psoriasis as the main indication for biologic use (e.g. patient receives biologic for rheumatoid arthritis as the main indication).
- - Concomitant use of systemic immunosuppressants other than methotrexate or acitretin (e.g. prednisone, cyclosporine etc).
- - Severe comorbidities with short life-expectancy (e.g. metastasized tumor).
- - Presumed inability to follow the study protocol.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.
The person who is responsible for the scientific and technical direction of the entire clinical study.

Rationale: Biologics are very effective treatments for psoriasis. Research indicated that the dose of TNFα-blocking biologics can be reduced in a proportion of patients. Safety profiles can improve and costs can be reduced if the reduction of the dose is successful. Recently, the newest generation of biologics entered the market: interleukin (IL) 17 and IL23 inhibitors. It is not yet known whether dose reduction of these agents is possible, and to what extent they can be reduced. The timely investigation of the possibilities for dose reduction of new biologics is therefore important. Objectives: The primary goal is to investigate whether controlled dose reduction of IL17 or IL23 inhibiting biologics is not inferior compared to usual care. This is measured by comparing the proportion of long-term disease flares between the two groups (dose reduction group versus usual care group). Secondary goals are: determining the proportion of patients with successful dose reduction, clinical effectiveness measured with the Psoriasis Area and Severity score (PASI) score, Dermatology Life Quality Index (DLQI) scores, predictors for successful dose reduction, safety, and cost-effectiveness of dose reduction. Pharmacokinetic (PK) analysis will be performed for modeling. Study design: a multicenter, practice-oriented, pragmatic, randomized, controlled, non-inferiority study. Study population: Patients treated with the newest generation of biologics (IL17 or IL23 inhibitors), with long-term stable low disease activity at a normal dose. A total of 244 patients will be randomized (2:1) to dose reduction or continuation of usual care. Intervention: Dose reduction by interval prolongation in 2 steps to a maximum decrease of 50% of the original dose when disease activity (PASI) and quality of life index (DLQI) remain low.
Experimental: Dose reduction
Dose reduction by interval prolongation in 2 steps to a maximum decrease of 50% of the original dose when disease activity (PASI) and quality of life index (DLQI) remain low.
