2026年5月13日 更新者:Galderma R&D

一项多中心、开放标签、正在使用的研究,旨在评估外用护肤品对银屑病患者的功效和耐受性

患有轻度至重度斑块状银屑病、具有活性目标病变斑块、并且目前正在或开始斑块状银屑病处方治疗的受试者将在身体的一侧应用局部护肤方案。 该方案的疗效评估将在基线后 2 周、4 周和 8 周进行。

详细说明

这是一项多中心、开放标签、正在使用的研究。 将招募患有轻度至重度斑块状银屑病、具有活动目标病变斑块、并且目前正在或开始斑块状银屑病处方治疗的成年受试者参与该研究。

受试者将在基线(第 0 天)访视时向现场报告,并获得需要填写的知情同意书、HIPAA 表、照片授权表和病史表。

将根据学习资格的选择标准对受试者进行筛选。 符合条件的受试者将在基线访视时接受评估,并指示根据预先确定的随机分组开始将护肤产品涂抹到指定的身体一侧。

受试者在第 2 周(± 3 天)、第 4 周(± 5 天)和第 8 周(± 5 天)返回现场进行随访。

大体时间
Change in Psoriatic Body Surface Area Compared to Baseline
大体时间:Baseline, Week 2, Week 4, Week 8
Body Surface Area is a measure of how much skin is impacted by psoriasis using the following measurement.7 One handprint is equal approximately to 1% of Body Surface Area. A decrease in scores indicated an improvement.
Baseline, Week 2, Week 4, Week 8
Change in Target Lesion Severity Compared to Baseline
大体时间:Baseline, Week 2, Week 4, Week 8
Target lesion severity was measured by the Target Lesion Severity Score. Target Lesion Severity Score assessed erythema, induration, and scaling separately on a scale of 0-8, with 0 meaning no evidence of the parameter and 8 meaning very severe presence of the parameter. Target Lesion Severity Score was calculated as cumulative total of all 3 parameters, which a maximum score of 24 (8 x 3) and minimum score of 0. Total scale range is 0-24, where higher scores are worse outcomes. A decrease in scores indicated an improvement.
Baseline, Week 2, Week 4, Week 8
Change of Physician Global Assessment Compared to Baseline
大体时间:Baseline, Week 2, Week 4, Week 8

Favorable responses (i.e., strongly agree and agree, yes), neutral responses (i.e., neither agree nor disagree, no difference), and unfavorable responses (i.e., strongly disagree and disagree, no) were tabulated as appropriate. Number of participants with favorable responses was provided for each question.

Changes in Dryness Compared to Baseline [Tolerability Assessment]
大体时间:Baseline, Week 2, Week 4, Week 8
Tolerability assessment was performed by the Investigator (parameter: dryness) using a 4-point analog scale (with half-point scores used as necessary to better describe the clinical condition). Investigator graded the degree of irritation of target lesion areas on a scale of 0 to 3, with 0 meaning parameter is not present, and 3 meaning parameter is severely present. A decrease in scores or lack of significant increase indicated tolerability/safety of the treatment products.

大体时间
Subject Quality of Life Satisfaction
大体时间:Baseline, Week 8
Subjects were asked about their life quality by completing a Quality of Life questionnaire of 10 questions. Each question is scored from 0-3, with 0 being "not at all" or "not relevant" and 3 being "very much". All scores were summed to determine the Dermatology Quality of Life Index with score range 0-30: 0-1 (no effect at all on patient's life), 2-5 (small effect), 6-10 (moderate effect), 11-20 (very large effect), 21-30 (extremely large effect). A decrease in score totals from baseline to Week 8 indicated an improvement. A higher score indicates a greater impairment of quality of life.
