NCT02602925

Brief Summary

Rationale/hypothesis: Moderate-to-severe psoriasis can be treated with biologics. Objective To investigate whether the dose of biologics can be reduced in patients with psoriasis with stable disease. Study design: A pragmatic, multicentre, randomized, controlled, non-inferiority study with cost-effectiveness analysis. Study population: Patients with disease remission using normal dose of biologics. Intervention: 120 patients will be randomized into two groups: (1) dose reduction and (2) normal dose. Main study parameters/endpoints: The primary outcome is clinical effectiveness. Secondary outcomes are: health-related quality of life (HRQoL), number and time to disease flares, costs, health status, anti-drug antibody formation and serious adverse events

Outcome Measures

Primary Outcomes (1)

  • Disease-activity

    Disease-activity measured by Psoriasis Area and Severity Index (PASI), effectiveness measure used in most psoriasis trials.

    1 year

Secondary Outcomes (10)

  • Health-related quality of life (HRQoL-DLQI)

    1 year

  • Number of patients with 1 or more persistent flares

    1 year

  • Disease-activity measured with HsCRP

    1 year

  • Predictors for succesful dose decrease (treatment and patient characteristics)

    1 year

  • Anti-drug antibody levels against etanercept, adalimumab or ustekinumab

    1 year

  • +5 more secondary outcomes

Study Arms (2)

Dose decrease

EXPERIMENTAL

Patients receive daily practice care, but doses of etanercept, adalimumab or ustekinumab will be lowered: intervals of drug-administration will be prolonged stepwise with tight control of disease activity and DLQI. First, the dose will be decreased to 66-70% of the normal dose (by interval prolongation with a factor 1.5). If patients remain in a state of low disease activity, the dose will be further reduced to 50% (by doubling the original interval). Each step will be analyzed after three months, or when the patient visits earlier due to complaints.

Other: Dose decrease

Usual care

OTHER

Patients will continue treatment with the normal dose and treatment regimens will be based on usual daily practice care. Treatment decisions are made at the discretion of the treating physician.

Other: Usual care

Interventions

Treatment strategy change: dose decrease based on PASI and DLQI

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Sustained low disease activity as described above on the 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.
  • Ability to understand informed consent, read and answer questionnaires.

You may not qualify if:

  • 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 immunosuppressants other than methotrexate or acitretin for psoriasis.
  • Severe comorbidities with short life-expectancy (e.g. metastasized tumour).
  • Presumed inability to follow the study protocol.
