| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| We aim to investigate whether we could taper the biologics dose in psoriasis patietns with stable disease-activity and good quality of life. The primary research question for this proposal is: Is a biologics dose tapering strategy non-inferior to usual care with respect to disease activity? |
|
| E.2.2 | Secondary objectives of the trial |
| Secondary questions are: Is quality of life (DLQI) maintained during dose tapering? Are there factors that predict successful dose tapering? How cost-effective is dose tapering in this group? How does dose-tapering change the safety profile regarding side-effects or antibody formation? |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
• Sustained low disease activity (PASI<5 for at least 6 months, DLQI <5 at inclusion) on the regular dose as advised by the label.
• Established diagnosis of plaque psoriasis.
• Receiving treatment with adalimumab, etanercept, or ustekinumab for at least 6 months.
• Age ≥18 years. |
|
| E.4 | Principal exclusion criteria |
• Psoriasis itself is not the main reason for biologic prescription (e.g. when a patient has RA and psoriasis, and RA is the main reason for the biologic).
• Concomitant use of immunosupressants other than methotrexate or acitretin for psoriasis.
• Severe comorbidities with short life-expectancy (e.g. metastasized tumour).
• Presumed inability to follow the study protocol.
