E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
This study will evaluate the anti-pruritic effect of apremilast in patients with known PN.
1. Reduction in mean absolute VAS-pruritus score after 12 weeks treatment with apremilast compared to mean VAS-pruritus score before treatment with apremilast |
Dette er et interventionsstudie, hvor vi vil vurdere effekten af apremilast mod kløe til patienter med kendt prurigo nodularis.
• Reduktion i absolutte mean VAS-kløe (bilag 1) efter behandling med apremilast i 12 uger sammenlignet med mean VAS-kløe før behandling med apremilast. |
|
E.2.2 | Secondary objectives of the trial |
1. Reduction in PGA score after 12 weeks treatment with apremilast compared to PGA score before treatment with apremilast. A decrease in PGA score of at least 2 points from baseline level will be considered as a successful reduction
2. Reduction in DLQI score after 12 weeks treatment with apremilast compared DLQI score before treatment with apremilast
3. Reduction in PtGA score after 12 weeks treatment with apremilast compared to PtGA score before treatment with apremilast
4. Improvement in sleep quality after 12 weeks treatment with apremilast compared to sleep quality before treatment with apremilast using a self-administered questionnaire.
5. Reduction in level of inflammatory cytokines in blood after 12 weeks treatment with apremilast compared to inflammatory cytokine level before treatment with apremilast
6. Increase in level of IL-10 (anti-inflammatory cytokine) in blood after 12 weeks treatment with apremilast compared to IL-10 level before treatment with apremilast
|
• Reduktion i PGA score efter behandling med apremilast i 12 uger sammenlignet PGA score før behandling med apremilast. Et fald i PGA score på mindst 2 point fra baseline level vil blive betragtet som et positivt resultat.
• Reduktion i DLQI score efter behandling med apremilast i 12 uger sammenlignet med DLQI score før behandling med apremilast
• Reduktion i PtGA score efter behandling med apremilast i 12 uger sammenlignet med PtGA score før behandling med apremilast
• Forbedret søvnkvalitet efter behandling med apremilast i 12 uger sammenlignet søvnkvalitet før behandling med apremilast. Monitoreres ved spørgeskema (PSQI) omhandlende søvnkvalitet
• Reduktion i antal af inflammatoriske cytokiner i blod efter behandling med apremilast i 12 uger sammenlignet med antal af inflammatoriske cytokiner før behandling med apremilast.
• Stigning i IL-10 i blod efter behandling med apremilast i 12 uger sammenlignet IL-10 niveau før behandling med apremilast

1. Behandling med lokal antiinflammatorisk medicin inden for 2 uger før forsøgets påbegyndelse
2. Behandling med systemisk antiinflammatorisk medicin inden for 4 uger før forsøgets påbegyndelse
3. Behandling med forsøgsmedicin inden for 4 uger før baseline
