プラーク型乾癬および非膿疱性掌蹠乾癬の治療における医療機器PROXERA PSOMED 20およびPROXERA PSOMED 40に関する臨床研究 (PASI)
医療機器PROXERA PSOMED 20による乾癬性プラークの減少、および医療機器PROXERA PSOMED 40による非膿疱性掌蹠乾癬欠損の減少の有効性と安全性の評価:プラーク型乾癬患者を対象としたスポンサード、介入、単一施設、無作為化、単盲検、患者内対照試験(PASI)
この単一施設介入研究は、2つのCEマークを取得した局所用医療機器の有効性と安全性を評価するために設計されました:PROXERA PSOMED 20は非手掌足底斑状乾癬の参加者を対象に研究され、PROXERA PSOMED 40は非膿疱性手掌足底乾癬の参加者を対象に研究されています。
本研究は、割り当てられた医療機器で標的領域を治療することが、同じ参加者の未治療の対側対照領域と比較して、より大きな臨床的改善につながるかどうかを判断することを目的としています。 PROXERA PSOMED 20では、主要評価は4週間の治療後に実施されます。 PROXERA PSOMED 40では、主要評価は8週間の治療後に実施されます。
副次的な目的には、安全性、局所耐容性、全体的な乾癬の進行、生活の質への影響、および標的領域における局所疾患活動性の追加パラメーターの評価が含まれます。 参加者は、割り当てられた研究機器を選択した標的領域に1日1回塗布し、予定された来院時に臨床評価を受け、研究を通じて安全性と耐容性に関する情報を提供します。

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