About this study

Official title: Tight Control Dose Reductions of Biologics in Psoriasis Patients With Low Disease Activity: A Randomized Pragmatic Trial

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.

Read more

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

Read the detailed description

Rationale/hypothesis: Moderate-to-severe psoriasis can be treated with biologics. These drugs have significantly improved the quality of life of psoriasis patients, but are very expensive drugs that should be used as efficiently as possible. In addition, the long-term safety profile can probably be improved if patients receive the lowest effective dose.

Objective To investigate whether the dose of biologics can be reduced in patients with psoriasis with stable disease: Is dose reduction non-inferior to the current practice regarding clinical effectiveness? Secondary aims are: to investigate what influence dose tapering has on quality of life, whether there are predictors for successful dose reduction, and to determine the cost-effectiveness of dose reduction.

Study design: A pragmatic, multicentre, randomized, controlled, non-inferiority study with cost-effectiveness analysis.

Study population: Patients who used a biologic for at least 6 months (etanercept, adalimumab, ustekinumab) can be included if they have long-term stable low disease activity. Low disease activity is defined as a PASI score (Psoriasis Area and Activity Score) <5 and a health-related quality of life score ≤5 (Dermatology Quality of life index: DLQI).

Intervention: 120 patients will be randomized into two groups: (1) dose reduction guided by PASI and DLQI (n=60, intervention) and (2) maintenance of normal dosage (n=60, usual care).

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

Study groups in NCT02602925
Study groupRoleWhat they receive
Dose decreaseExperimentalPatients 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.
Receives: Other: Dose decrease
Usual careOtherPatients 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.
Receives: Other: Usual care

What is being measured

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

  1. Disease-activity

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

    Measured: 1 year

Secondary outcomes (10)
  1. Health-related quality of life (HRQoL-DLQI)

    HRQoL(Dermatology Life Quality Index (DLQI)

    Measured: 1 year

  2. Number of patients with 1 or more persistent flares

    Number of patients with 1 or more persistent flares (persistent flare is defined as at least 3 months PASI increase >5 or DLQI >5)

    Measured: 1 year

  3. Disease-activity measured with HsCRP

    High-sensitivity CRP, a possible marker for disease-activity

    Measured: 1 year

  4. Predictors for succesful dose decrease (treatment and patient characteristics)

    For both groups, patient (sex, age, PsA, comorbidities) and treatment characteristics (antibody formation, through levels of drug, dose of biologic, drug pauses, use of concomitant antipsoriatic systemic drugs (dose and duration of use), use of topical therapies during treatment (steroid class and duration of use)) will be collected. These will be used to identify predictors for successful dose reduction.

    Measured: 1 year

  5. Anti-drug antibody levels against etanercept, adalimumab or ustekinumab

    Anti-drug antibodies (AU/mL) of the used biologic (etanercept, adalimumab or ustekinumab) will be measured using enzyme-linked immunosorbent assay or ELISA. Measures will take place at baseline and every study visit (week 0, 12, 24, 36 and 49). Anti-drug antibody levels will be used to assess whether they predict successful dose decrease.

    Measured: 1 year

  6. Drug trough levels of etanercept, adalimumab or ustekinumab

    Drug trough levels (mg/l) of the used biologic (etanercept, adalimumab or ustekinumab) will be measured using enzyme-linked immunosorbent assay or ELISA. Measures will take place at baseline and every study visit (aprox. every 3 months). Anti-drug antibody levels will be used to assess whether they predict successful dose decrease.

    Measured: 1 year

  7. Number of serious adverse events per patient

    All serious adverse events (SAE) during study participation and their causal relation with the biologic will be assessed.

    Measured: 1 year

  8. Costs related to medical consumption

    For cost-effectiveness analyses, questionnaires iMTA MCQ (medical consumption questionnaire) will be administered in each group at every study visit except baseline (week 12, 24, 36, 49).Data will be incorporated and presented in a cost-effectiveness analysis.

    Measured: 1 year

  9. Costs related to productivity

    For cost-effectiveness analyses, questionnaire iMTA PCQ (productivity cost questionnaire) will be administered in each group at every study visit except baseline (week 12, 24, 36, 49).Data will be incorporated and presented in a cost-effectiveness analysis.

    Measured: 1 year

  10. Health status (SF36)

    SF-36v2 questionnaire will be used to measure health status. Outcomes will be presented seperataly (scores for mental and physical health domain); but will also be incorporated and presented in a cost-effectiveness analysis. Questionnaire will be administered every study visit except baseline (week 12, 24, 36, 49).

    Measured: 1 year
