Data demonstrated favorable safety and local tolerability of ZORYVE® (roflumilast) cream 0.15% in adults and children with atopic dermatitis (AD) with prior inadequate response, intolerance, and contraindications to topical treatments New patient reported outcome data for investigational ZORYVE® (roflumilast) foam 0.3% demonstrated favorable efficacy, safety, and local tolerability data in scalp and body psoriasis In the United States, AD affects approximately 26 million adults and children and psoriasis affects approximately 9 million adults and children, with more than half experiencing involvement of the scalp WESTLAKE VILLAGE, Calif. and ORLANDO, Fla., March 07, 2025 (GLOBE NEWSWIRE) -- Arcutis Biotherapeutics, Inc. (Nasdaq: ARQT), a commercial-stage biopharmaceutical company focused on developing meaningful innovations in immuno-dermatology, today announced new data from two posters shared at the 2025 American Academy of Dermatology Annual Meeting (AAD). The first poster presentation details the positive efficacy, patient reported outcomes, and tolerability for the use of once-daily ZORYVE cream 0.15% in adults and children 6 years and older with mild to moderate AD from the INTEGUMENT 1-2 trials (n=1,337) who reported a prior inadequate response, intolerance or contraindication to topical corticosteroids (TCS; 60.8%), topical calcineurin inhibitors (TCI; 18.1%), or crisaborole (7.3%). At all timepoints assessed during the four-week trial, more than 91% of participants reported no or mild sensation at the application site and investigators reported no irritation or minimal erythema (redness) in ≥ 97% of participants in these subgroups. Improvement in AD was observed across multiple efficacy endpoints and safety was consistent with the overall study population. A second poster presentation shares results from the Phase 3 ARRECTOR trial that outlines improvements in patient-reported outcomes with investigational ZORYVE foam 0.3% compared with vehicle in adults and children aged 12 or older with psoriasis of the scalp and body. ZORYVE foam significantly improved quality of life across the 23-component Scalpdex assessment throughout the eight-week study period. Individuals reported an improvement in symptoms as well as a reduction in how psoriasis impacted their daily life (e.g., embarrassment, stress, affecting clothing choices, or hair styles). “While topical therapies are the first line of therapy for millions of people with atopic dermatitis, there are many who are contraindicated or have an inadequate or intolerant response to topical therapies, which have previously been considered the standard of care. These data add to the large body of evidence that highlights the effectiveness, safety, and tolerability of ZORYVE cream 0.15% across diverse patient types, making it a suitable targeted topical and alternative to steroids for adults and children with atopic dermatitis,” said Patrick Burnett, MD, PhD, FAAD, chief medical officer at Arcutis. “In addition, the patient reported outcome data being shared at AAD underscores our team’s commitment to finding meaningful innovations for immuno-dermatologic conditions like psoriasis that can have a significant physical and emotional impact on the individuals that live with these chronic conditions and their caregivers.” The posters will be available electronically during the meeting in the exhibition poster hall beginning Friday, March 7, 2025.

特异性皮炎（Atopic Dermatitis，AD）是一种慢性容易复发的皮肤炎性疾病，具有高患病率、高疾病负担的特点，给患者的生活质量带来了严重影响。近年来，随着对AD疾病机制研究的不断深入以及新型药物的研发，全球AD的治疗格局正在重塑，本文旨在梳理特异性皮炎的发病机理、在研药物、市场情况等，以期与读者共同学习并了解这一疾病领域现状。一、流行病学研究1、全球发病现状 流行病学数据显示，AD是全球非致命性疾病中疾病负担排名第15位的皮肤病，全球患者数超2.3亿，中重度患者占比约30%-40%[1]。其中儿童发病率为10%-20%，成人发病率为1%-3%。儿童期发病患者中，约50%的症状会持续至成年，且常伴随过敏性鼻炎、哮喘等并发症。成人AD患者中，心血管疾病、抑郁症和自身免疫性疾病共病风险显著增加[2]。2、国内发病现状 在我国的AD患者约7000万，其中中重度患者超2000万，儿童患病率从1998年的3%上升至2023年的12%-15%[3]。我国婴幼儿期的患病率约为30.48%，1-7岁学龄前儿童为12.94%，成人约为10.6%。近年来，随着社会和生活习惯的改变，AD患病人数不断增加，至2020年已超过6700万人，预计到2025年将超过7500万人。特异性皮炎的发病主要与生活环境、生活方式、遗传因素和心里因素有关。城市化、空气污染（如PM2.5）、气候变化以及室内环境（如宠物毛发、尘螨）、高糖高脂饮食、过度清洁等均会造成AD病情加重[4-5]。 二、发病机制 AD的发病机制复杂，涉及皮肤屏障功能障碍、免疫失调、微生物组失衡、神经免疫相互作用 及遗传与环境因素的交互作用。1、皮肤屏障功能障碍：主要诱因为丝聚蛋白（Filaggrin，FLG）基因突变。约30%-50%的AD患者存在FLG基因突变，导致角质层结构蛋白减少，皮肤屏障完整性受损。另一种诱因是皮肤角质层脂质代谢异常，神经酰胺合成减少，胆固醇和游离脂肪酸比例失衡，削弱了皮肤的保水能力。皮肤屏障被破坏，直接导致外界过敏原（如尘螨、花粉）和病原体（如金黄色葡萄球菌）更易穿透皮肤，触发免疫反应。 图1、Filaggrin代谢与皮肤屏障结构示意图[6] 2、免疫失调与Th2型炎症刺激：先天免疫异常可能引起炎性刺激，角质形成细胞释放胸腺基质淋巴细胞生成素（TSLP）、IL-25和IL-33，激活2型固有淋巴细胞（ILC2）和树突状细胞。而适应性免疫失衡将引起Th2主导、Th17/Th22参与的免疫反应，其中IL-4、IL-13、IL-31驱动瘙痒和炎症；IL-5促进嗜酸性粒细胞浸润；慢性期病变中IL-17和IL-22则会加重表皮增生和炎症。 图2、AD免疫通路（Th2/Th17/Th22）与关键细胞因子网络[7] 3、微生物组失衡/金黄色葡萄球菌定植：AD患者皮肤表面常存在菌群失调的现象。皮肤表面金黄色葡萄球菌（S. aureus）过度增殖，分泌δ-毒素和蛋白酶，破坏屏障并激活TLR2/TLR4信号通路。S. aureus进一步通过生物膜形成和抗菌肽抵抗（如LL-37降解）逃避免疫清除。 图3、AD患者皮肤微生物组动态变化与炎症关系[8]4、神经免疫相互作用与瘙痒机制：由Th2细胞分泌的IL-31，直接激活感觉神经元表面的IL-31受体（IL-31RA），诱发瘙痒，患者搔抓进一步破坏屏障，释放更多细胞因子（如TSLP），形成恶性循环；神经肽（如Substance P） 促进肥大细胞释放组胺和TNF-α，加剧炎症。 图4、IL-31/IL-13/IL-4信号通路与神经元激活机制[9]5、遗传与环境触发因素：FLG、SPINK5（LEKTI蛋白酶抑制剂）、IL-4Rα等基因多态性增加AD风险；空气污染物（PM2.5）、硬水、过度清洁、压力等通过表观遗传修饰（如DNA甲基化）加剧炎症。 图5、AD遗传与环境交互作用示意图[10] 三、AD的治疗药物 （一）外用药物 特应性皮炎的化学药品治疗手段主要包括外用药物和系统用药。外用药物主要为糖皮质激素，也是AD的一线外用治疗手段，具有抗炎、抗过敏和免疫抑制的作用。根据强度不同，分为弱效、中效、强效和超强效。弱效糖皮质激素（如氢化可的松）适用于轻度皮损和面部、褶皱部位；中效（如曲安奈德）和强效（如卤米松）适用于中重度皮损。 另外，钙调磷酸酶抑制剂（TCI）如他克莫司软膏和吡美莫司乳膏是非激素类外用药物，适用于对糖皮质激素不耐受或需要长期维持治疗的患者，尤其适合用于面部和褶皱部位。 此外，PDE4抑制剂（如克立硼罗软膏）、TRPV1拮抗剂（PAC-14028乳膏）、AhR调节剂等，均能抑制下游炎性反应，改善并缓解AD症状，恢复皮肤屏障。 图6、针对AD适应症的化药药品（整理自药渡数据库） （二）系统用药及辅助治疗 口服抗组胺药物（H1受体拮抗剂）对AD相关瘙痒和皮疹的改善效果有限，但可在一定程度上缓解夜间瘙痒。当AD患者出现金黄色葡萄球菌感染时，需使用抗生素进行局部或系统治疗。采取窄波UVB或UVA1光疗等辅助治疗手段，可用于中重度AD患者的辅助治疗。 （三）生物制剂 生物制剂是当前AD治疗领域的研究热点。靶向IL-4/IL-13通路抑制剂、靶向TSLP抑制剂、微生物组疗法、基因疗法、干细胞疗法等针对AD的新兴治疗手段百花齐放。 图7、针对AD适应症的生物药品（整理自药渡数据库） 1、自免类单克隆抗体： 1）赛诺菲/再生元的普利尤单抗（Dupilumab，IL-4Rα单抗），通过抑制白细胞介素-4（IL-4）和白细胞介素-13（IL-13）的信号通路，减少2型炎症反应，在特异性皮炎的治疗中表现出显著的临床效果。 u在一项长达5年的临床研究中，Dupilumab显示出持续的疗效，80%的患者湿疹症状得到良好控制，约2/3的患者用药频率逐渐降低至每3-4周一次。 u真实世界研究中，Dupilumab治疗中重度AD患者2年后，患者的湿疹面积和严重程度指数（EASI）、瘙痒评分（P-NRS）、生活质量指数（DLQI）等指标均显著改善，且安全性良好。 u对于6个月至5岁的中重度AD患儿，Dupilumab联合低效糖皮质激素治疗可在短期内显著缓解瘙痒和皮损，改善患儿及照料者的睡眠质量和生活质量。 u在6-11岁儿童中，Dupilumab治疗可在2周内显著改善AD体征和症状，并持续至16周，即使部分患者皮肤未完全清除，症状也显著改善。 u在12-18岁青少年中，Dupilumab治疗16周后，显著改善了AD的症状和生活质量，且安全性良好。 2）礼来的来瑞奇珠单抗（Lebrikizumab，IL-13单抗），能够特异性结合IL-13，阻止IL-13Rα1/IL-4Rα异二聚体复合物的形成，从而抑制IL-13的信号传导。在关键III期临床试验（Advocate 1和Advocate 2）中，接受Lebrikizumab治疗的患者在16周后皮肤症状消失或几乎消失的比例为38%，而安慰剂组仅为12%。此外，43%的患者在16周时瘙痒症状显著缓解。在维持治疗阶段，77%的患者在每月一次的维持剂量下，一年后仍保持皮肤症状的显著改善。与安慰剂相比，Lebrikizumab在治疗早期（如第4周）即可显著改善症状，部分患者在第2周即开始感受到瘙痒缓解。 3）在我国，康诺亚公司的司普奇拜单抗（IL-4Rα单抗）、康哲药业的CM310（IL-4Rα单抗）、康方生物的AK120（IL-4Rα单抗）、三生国健的SSGJ-613（IL-13单抗）等在不同的临床研究中均展示出各自的药物有效性，提示了我国在自身免疫疾病和特异性皮炎治疗领域取得了显著进展。 图8、国内治疗AD的单克隆抗体基本情况 4）新靶点TSLP抑制剂：Thymic Stromal Lymphopoietin（TSLP）是一种上皮细胞因子，位于炎症级联反应的顶端，在除OA外的多种炎性疾病（如哮喘、慢性鼻窦炎伴鼻息肉等）中发挥关键作用，能够触发多种炎症反应。通过高效阻断TSLP，Tezepelumab能够减少促炎细胞因子的释放，减轻炎症反应，改善患者的临床症状。目前针对AD的II期临床研究仍在进行中，更多数据尚未完全披露。2、调节微生物组/细菌替代疗法： 1）FB-401（Forte Biosciences）：结合三种罗氏菌属（Roseomonas mucosa）菌株，通过激活Toll样受体5（TLR5）和肿瘤坏死因子受体（TNFR）发挥抗炎和组织修复作用。在I/IIa期研究中，60%的成人患者SCORAD评分降低50%，90%的儿童患者达到EASI 50，30%达到EASI 90。 2）EDP1815（Evelo Biosciences）：通过调节系统性炎症，改善AD症状。相关I期研究正在进行中。 3、干细胞治疗 间充质干细胞以其产品的免疫抑制与损伤修复这两大功能特性，也进入了AD这一赛道。 1）易文赛生物技术有限公司的脐带源间充质干细胞，在一项I/II期临床研究纳入34例中重度AD患者，皮下注射2.5×107或5.0×107 hUC-MSCs。结果显示高剂量组中55%的患者湿疹面积和严重程度指数（EASI）评分降低50%；瘙痒评分降低58%，且未见严重不良事件报告。 2）脂肪间充质干细胞（hAD-MSCs）在一项I/II期临床研究纳入50例65岁以上重度AD患者，静脉输注5.0×107 hAD-MSCs。结果显示患者湿疹面积显著改善，瘙痒缓解，且随访14个月未复发。 4、基于生物标志物的精准医疗及个性化治疗方案 随着对AD病理生理学的深入研究，生物标志物在疾病诊断、治疗靶点选择及疗效评估中的重要性日益凸显。精准医疗作为一种新兴的医疗模式，强调基于患者的个体特征（如基因信息、生物标志物等）制定个性化治疗方案，以提高治疗效果并减少不良反应。在AD治疗领域，精准医疗的应用逐渐成为研究热点，特别是针对特定细胞因子通路的靶向治疗策略，如IL-31Rα、OSMRβ和mIgE等生物标志物的靶向药物研发，为AD的个性化治疗提供了新的方向 1）IL-31Rα抑制剂（Nemolizumab） Nemolizumab是一种针对IL-31受体α（IL-31Rα）的单克隆抗体。IL-31是一种由Th2细胞产生的细胞因子，与AD患者中的瘙痒症状密切相关。通过阻断IL-31与其受体的结合，Nemolizumab可以显著减轻瘙痒感，从而改善患者的生活质量。在一项III期研究中，Nemolizumab显示出显著改善瘙痒症状的效果，具体表现为患者瘙痒评分的显著降低，且这种改善在治疗过程中持续存在。研究还表明，Nemolizumab对瘙痒的改善效果独立于其他临床症状的改善，这意味着即使皮肤炎症没有完全消退，患者的瘙痒感得到了显著缓解。此外，Nemolizumab的安全性良好，未发现严重的不良反应，使其成为一种有潜力的AD治疗选择。 2）OSMRβ抑制剂（Vixarelimab） Vixarelimab是一种针对Oncostatin M受体β（OSMRβ）的单克隆抗体。IL-31信号通路涉及IL-31与其受体复合物（包括IL-31Rα和OSMRβ）的结合，从而引发下游的信号传导，导致瘙痒和炎症反应。Vixarelimab通过阻断OSMRβ，抑制IL-31信号通路的激活，从而减轻瘙痒症状。已被美国FDA授予突破性疗法认定，用于治疗与结节性痒疹相关的瘙痒。这表明其在缓解瘙痒症状方面具有显著的潜力。此外，Vixarelimab的安全性良好，未发现用药相关的严重不良反应，有望成为多种炎症性疾病的治选择。 3）mIgE靶向治疗（FB825/anti-CεmX） FB825是一种针对膜IgE（mIgE）的单克隆抗体。IgE在AD的发病机制中起着关键作用，尤其是在过敏反应和瘙痒信号传导中。通过靶向mIgE，FB825可以减少IgE介导的过敏反应，从而减轻AD症状。目前，FB825正在进行IIa期研究，旨在评估其在AD患者中的安全性和有效性。初步研究结果显示，FB825在降低IgE水平和改善AD症状方面具有潜力，尤其是在减少瘙痒和炎症方面。该研究还在评估FB825对不同亚型AD患者的疗效，以确定其在个体化治疗中的应用潜力。 图9、特异性皮炎的在研治疗药物[10] 四、研发挑战与解决策略 在AD的治疗中，中重度患者仍面临诸多未满足的需求。目前的治疗手段仍存在诸多局限性，尤其是在长期治疗的安全性和有效性方面。 1、传统治疗手段仍有局限性，糖皮质激素是治疗中重度AD的传统选择，但长期使用可能导致一系列副作用，包括皮肤萎缩、色素沉着、向心性肥胖、骨质疏松、血糖升高、感染风险增加等。此外，糖皮质激素的长期使用还会导致耐受，疗效逐渐降低。而口服免疫抑制剂（如环孢素、甲氨蝶呤等），虽然在控制炎症方面有一定效果，但其副作用较为严重。长期使用可能导致肝肾功能损伤、骨髓抑制（如白细胞减少、贫血）、胃肠道反应（如恶心、呕吐）、感染风险增加，甚至可能增加患癌风险。 2、生物制剂的局限性 生物制剂（如IL-4/IL-13单抗等）疗效虽好，但其价格较高，容易造成患者经济负担；而且抗体药物给药周期较长，需要定期注射，增加了患者的治疗负担病影响患者顺应性。 针对（1-2）的局限，我们的治疗策略正在从传统的Th2通路逐步扩展至神经免疫（IL-31）、上皮屏障（IL-33）以及OX40等新兴机制。多元化靶点的开发旨在更加全面的覆盖复杂病理机制，为不同亚型的AD患者提供更精准的治疗选择。 3、未被满足的治疗需求，不同患者的病情严重程度、病因和对药物的耐受性存在差异，因此需要更加精准的个体化治疗方案。解决策略：JAK抑制剂的研发正朝着更高选择性的方向发展，例如JAK1特异性抑制剂的出现显著降低了对其他JAK亚型的非特异性抑制，从而减少了不良反应。此外，外用制剂的开发也在逐渐减少全身暴露，进一步提升药物的安全性。以生物标志物（如IgE水平、TARC）为基础的个性化治疗应用正逐渐成为指导用药的重要工具。通过精准匹配患者亚型，个体化治疗方案能够提高治疗效果，同时减少不必要的药物暴露。 4、未来重点开发方向：可考虑联合用药策略，通过生物制剂与外用药物、免疫调节剂或光疗的联合使用，以期增强疗效并减少单一药物的剂量，降低副作用。开发长效缓释制剂等新型药品，以满足患者的长期治疗需求。 五、总体市场机遇 我国特异性皮炎患者人数庞大且逐年增加，预计到2025年将超过7500万人，为药物市场提供持续需求。预计到2025年，中国特应性皮炎药物市场规模有望突破百亿元，未来市场空间广阔。随着医保水平提升，医保覆盖程度扩大，更多创新药物纳入医保，患者可及性增加。国内药企研究进展迅速，有望通过本土化的价格优势和医保覆盖，加速进口替代。 六、小结： 综上所述，特异性皮炎作为一种高患病率、高疾病负担的慢性皮肤病，市场需求巨大。随着不同靶点的生物制剂、免疫调节剂等新型药物的研发和上市，AD治疗将进入新的阶段。未来，随着更多创新药物的获批，AD药物市场有望持续扩容，为患者提供更多的治疗选择。我国的AD药物行业正处于创新转型期，国内企业正在加速布局，并在不断平衡疗效、安全性与可及性。相信不久的将来，IL-4Ra、IL-31等靶向药、细胞疗法、基因治疗或将成市场核心驱动力，为更多保守特异性皮炎困扰的患者带来福祉。
