PDE4 抑制脂溢性皮炎和丘疹脓疱性酒渣鼻
使用 PF-07038124 抑制 PDE4 治疗脂溢性皮炎和丘疹脓疱性酒渣鼻
本研究是一项双盲、媒介对照临床试验。 该研究将在西奈山伊坎医学院进行。 该研究将包括 33-39 名患有中度至重度脂溢性皮炎 (SD) 的成人受试者以及 33-39 名患有中度至重度丘疹脓疱性红斑痤疮 (PPR) 的成人受试者。 受试者将以 2:1 的比例随机分配接受研究药物或安慰剂。
登记受试者将外用 PF-07038124 0.02% 软膏,每日一次,持续 8 周。 他们将在研究治疗开始后第 4、8 和 12 周返回进行随访,以进行重复临床评估、药物审查、胶带剥离、血液和尿液样本采集以及不良事件监测。
研究概览
详细说明
在提供同意后,将评估所有受试者的研究资格,其中包括审查受试者过去和当前的医疗状况、家族病史以及详细审查过去和当前的药物治疗。 受试者还将接受对过去 SD 或 PPR 局部治疗/疗法的回顾,以及临床评估(SD:临床 SD 评分、IGA、峰值瘙痒数值评定量表 [PP-NRS];PPR:炎症病变计数、IGA、PP-国家标准局)。
符合纳入资格标准的受试者可以继续进行基线访视(第 0 周),或者可以安排在筛选访视后 28 天内返回进行基线访视。
在基线/第 0 周,受试者将接受临床评估(SD:临床 SD 严重程度评分、IGA、PP-NRS;PPR:炎症病变计数、IGA、PP-NRS)、伴随药物审查、标准化临床摄影和皮肤科检查生活质量指数(DLQI)问卷。 随后的临床评估,包括标准化临床摄影和问卷填写,将在第 4 周、第 8 周和第 12 周的随访时进行。将收集皮肤胶带样本,用于基线(病变和非病变)的机制研究(如下所述) -病变面部皮肤)、第4周(病变面部皮肤)、第8周(病变面部皮肤)和第12周(病变面部皮肤)。 将在基线和第 8 周(或提前终止,以先到者为准)收集并储存额外的血液样本,用于未来可能的机制分析。
