Klinische studie over de medische hulpmiddelen PROXERA PSOMED 20 en PROXERA PSOMED 40 voor de behandeling van plaque psoriasis en niet-pustuleuze palmoplantaire psoriasis (PASI)
Evaluatie van de werkzaamheid en veiligheid van het medische hulpmiddel PROXERA PSOMED 20 bij het verminderen van psoriatische plaques en van het medische hulpmiddel PROXERA PSOMED 40 bij het verminderen van niet-pustuleuze palmoplantaire psoriasislaesies bij patiënten met plaque psoriasis: een gesponsorde, interventionele, single-center, gerandomiseerde, enkelblinde, intra-patiënt gecontroleerde studie (PASI)
Deze interventiestudie in één centrum was ontworpen om de werkzaamheid en veiligheid van twee CE-gemarkeerde topische medische hulpmiddelen te evalueren: PROXERA PSOMED 20 wordt onderzocht bij deelnemers met niet-palmoplantaire plaque psoriasis, terwijl PROXERA PSOMED 40 wordt onderzocht bij deelnemers met niet-pustuleuze palmoplantaire psoriasis.
De studie heeft tot doel te bepalen of behandeling van een doelgebied met het toegewezen medische hulpmiddel leidt tot een grotere klinische verbetering in vergelijking met het onbehandelde contralaterale controlegebied bij dezelfde deelnemer. Voor PROXERA PSOMED 20 wordt de primaire beoordeling uitgevoerd na 4 weken behandeling. Voor PROXERA PSOMED 40 wordt de primaire beoordeling uitgevoerd na 8 weken behandeling.
Secundaire doelstellingen omvatten de beoordeling van veiligheid, lokale verdraagbaarheid, algemene psoriasisprogressie, de impact op de kwaliteit van leven, en aanvullende parameters van lokale ziekteactiviteit in de doelgebieden. Deelnemers zullen het toegewezen studiehulpmiddel één keer per dag aanbrengen op het geselecteerde doelgebied, klinische beoordelingen ondergaan tijdens geplande bezoeken, en gedurende de studie veiligheids- en verdraagbaarheidsinformatie verstrekken.

Experimenteel: Intra-patiënt Behandeling Met PROXERA PSOMED 20
Enkelgroep, gerandomiseerde, enkelblinde, intra-patiënt gecontroleerde studiearm.
Deelnemers worden toegewezen aan behandeling volgens diagnose: deelnemers met niet-palmoplantaire plaque psoriasis krijgen PROXERA PSOMED 20 eenmaal daags gedurende 4 weken op één doelplaquette, terwijl deelnemers met niet-pustuleuze palmoplantaire psoriasis PROXERA PSOMED 40 eenmaal daags gedurende 8 weken krijgen op één doelgebied van de handpalm of voetzool.
In beide cohorten blijft een vergelijkbaar contralateraal doelgebied onbehandeld als controle.
Voor PROXERA PSOMED 40 wordt de behandeling elke 14 dagen gedurende 3 dagen onderbroken.

Difference Between Treated and Untreated Target Plaques in Change From Baseline in Target Lesion Score at Week 4
Tijdsspanne: Baseline to Week 4 (end of treatment)
|
The Target Lesion Score assesses the severity of a representative psoriatic plaque based on erythema, induration (thickness), and scaling.
Each component is scored from 0 to 4, and the total score ranges from 0 to 12, with higher scores indicating greater lesion severity.
In participants treated with PROXERA PSOMED 20, the outcome compares the change from baseline to Week 4 in the treated target plaque with the change in the contralateral untreated control plaque.

Difference Between Treated and Untreated Target Areas in Change From Baseline in Local Modified Palmoplantar Psoriasis Area and Severity Index at Week 8
Tijdsspanne: Baseline to Week 8 (end of treatment)
|
The local modified Palmoplantar Psoriasis Area and Severity Index (mPPPASI) assesses erythema, induration, scaling, and extent of involvement in each target palm or sole area.
Erythema, induration, and scaling are each scored from 0 to 4, while extent of involvement is scored from 0 to 6.
For each target site, the local score is calculated as (erythema + induration + scaling) × extent and ranges from 0 to 72, with higher scores indicating more severe disease.
In participants treated with PROXERA PSOMED 40, the primary analysis compares the change from baseline to Week 8 in the treated target area with the change in the contralateral untreated control area.

Change From Baseline in Psoriasis Area and Severity Index Score at Week 4 in the PROXERA PSOMED 20 Cohort
Tijdsspanne: Baseline to Week 4 (end of treatment)
|
The Psoriasis Area and Severity Index (PASI) assesses overall psoriasis severity by combining the extent of body surface involvement with the severity of erythema, induration, and scaling across different body regions.
The total PASI score ranges from 0 to 72, with higher scores indicating greater overall psoriasis severity.
This outcome measures the change in PASI score from baseline to Week 4 in participants with non-palmoplantar plaque psoriasis treated with PROXERA PSOMED 20.
The assessment is used to determine whether changes observed in the target plaque occur independently of, or in parallel with, changes in overall psoriasis severity.
