Étude clinique sur les dispositifs médicaux PROXERA PSOMED 20 et PROXERA PSOMED 40 pour le traitement du psoriasis en plaques et du psoriasis palmoplantaire non pustuleux (PASI)
Évaluation de l'efficacité et de la sécurité du dispositif médical PROXERA PSOMED 20 dans la réduction des plaques psoriasiques et du dispositif médical PROXERA PSOMED 40 dans la réduction des lésions de psoriasis palmoplantaire non pustuleux chez les patients atteints de psoriasis en plaques : une étude parrainée, interventionnelle, monocentrique, randomisée, en simple aveugle, contrôlée intra-patient (PASI)
Cette étude interventionnelle monocentrique a été conçue pour évaluer l'efficacité et la sécurité de deux dispositifs médicaux topiques portant le marquage CE : PROXERA PSOMED 20 est étudié chez des participants atteints de psoriasis en plaques non palmoplantaire, tandis que PROXERA PSOMED 40 est étudié chez des participants atteints de psoriasis palmoplantaire non pustuleux.
L'étude vise à déterminer si le traitement d'une zone cible avec le dispositif médical attribué entraîne une amélioration clinique plus importante par rapport à la zone de contrôle controlatérale non traitée chez le même participant. Pour PROXERA PSOMED 20, l'évaluation principale est réalisée après 4 semaines de traitement. Pour PROXERA PSOMED 40, l'évaluation principale est réalisée après 8 semaines de traitement.
Les objectifs secondaires incluent l'évaluation de la sécurité, de la tolérance locale, de l'évolution globale du psoriasis, de son impact sur la qualité de vie, et de paramètres supplémentaires de l'activité locale de la maladie au niveau des zones cibles. Les participants appliqueront le dispositif d'étude attribué une fois par jour sur la zone cible sélectionnée, subiront des évaluations cliniques lors des visites programmées, et fourniront des informations sur la sécurité et la tolérance tout au long de l'étude.

Expérimental: Traitement intra-patient avec PROXERA PSOMED 20
Bras d'étude contrôlé intra-patient, en simple aveugle, randomisé, à groupe unique.
Les participants sont assignés au traitement selon le diagnostic : les participants atteints de psoriasis en plaques non palmoplantaire reçoivent PROXERA PSOMED 20 une fois par jour pendant 4 semaines sur une plaque cible, tandis que les participants atteints de psoriasis palmoplantaire non pustuleux reçoivent PROXERA PSOMED 40 une fois par jour pendant 8 semaines sur une zone cible de la paume ou de la plante du pied.

Difference Between Treated and Untreated Target Plaques in Change From Baseline in Target Lesion Score at Week 4
Délai: 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
Délai: 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
Délai: 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.
