过敏免疫舌下含片Acarizax获欧盟批准 用于青少年过敏性鼻炎

2017-04-19 newborn 新浪医药新闻

过敏免疫治疗领域的全球领导者ALK-Abello公司近日宣布其屋尘螨(house dust mite,HDM)过敏免疫舌下含片(SLIT)Acarizax获12个欧洲国家批准扩大适用人群,纳入12-17岁青少年患者,治疗由屋尘螨诱发的过敏性鼻炎。此次扩大批准,是基于全球性Acarizax临床开发项目在日本、北美开展的临床研究数据。研究结果证实,Acarizax用于12-17岁青少年患者治疗由屋尘螨


过敏免疫治疗领域的全球领导者ALK-Abello公司近日宣布其屋尘螨(house dust mite,HDM)过敏免疫舌下含片(SLIT)Acarizax获12个欧洲国家批准扩大适用人群,纳入12-17岁青少年患者,治疗由屋尘螨诱发的过敏性鼻炎。此次扩大批准,是基于全球性Acarizax临床开发项目在日本、北美开展的临床研究数据。研究结果证实,Acarizax用于12-17岁青少年患者治疗由屋尘螨诱发的过敏性鼻炎时,其疗效、安全性及耐受性与此前公布的Acarizax在成人患者群体中的数据一致。

根据ALK-Abello公司发布的新闻,Acarizax现在已获奥地利、捷克共和国、丹麦、芬兰、意大利、荷兰、挪威、波兰、瑞典、斯洛伐克、法国和德国等12个国家批准,用于12-17岁青少年患者群体。

在欧洲,Acarizax于2015年首次获批上市,用于成人患者群体,此次批准使Acarizax成为欧洲市场治疗过敏性哮喘的首个过敏免疫舌下含片(SLIT)产品。今年2月,来自Acarizax开发项目的临床数据使全球哮喘防治倡议(GINA)首次将过敏免疫疗法作为一种治疗选择纳入《哮喘管理预防的全球战略》。

截至目前,Acarizax已获全球17个国家批准,并已在9个国家上市销售。在美国,这款过敏舌下免疫含片于今年3月初获得美国食品和药物管理局(FDA)批准,用于18-65岁成人,治疗由屋尘螨(HDM)引起的伴或不伴眼部炎症(结膜炎)的鼻腔炎症(过敏性鼻炎),其品牌名为Odactra。此次批准,使Odactra成为美国市场首个通过舌下含服给药的过敏原提取物制剂,在该市场,ALK-Abello的合作伙伴默沙东(Merck & Co)拥有这款过敏舌下免疫含片的独家权利

屋尘螨(HDM)属于蛛形纲动物,只有0.1-0.5mm 大小,主要孳生于卧室内的枕头、褥被、软垫和家具中,以人体身上脱落下来的皮屑为食饵。对尘螨过敏的人,可能出现咳嗽、流鼻涕、鼻子发痒、鼻塞、打喷嚏、眼睛发痒、眼泪汪汪等症状。在全球范围内,屋尘螨(HDM)是导致过敏性反应的最常见原因。据估计,在欧洲、北美、日本有多达9000万人受屋尘螨(HDM)困扰;而在中国,受屋尘螨困扰的患者总数超过1亿人

Acarizax/Odactra是一种每日一次的舌下含片,全年服用,置于舌下后能够快速溶化。Acarizax/Odactra使患者暴露于屋尘螨过敏原,随着时间的推移,逐步训练机体免疫系统停止对所接触免疫原的异常反应,降低鼻部和眼部过敏症状的频率和严重程度。需要指出的是,患者在初次用药时,需在具有过敏性疾病诊断和治疗经验的医疗保健专家的监督下服用,同时需要观察至少30分钟,观测潜在的不良反应。如果首次服药的耐受性良好,患者后续可以在家自行服药。另外,在开始Acarizax/Odactra治疗后,患者应每日坚持服药,大约8-14周开始经历明显的症状缓解。

参芪是一种传统的中草药,并且被广泛的用于对过敏性鼻炎(AR)的治疗。最近,研究人员对参芪的抗过敏性鼻炎的活性和其潜在的分子机制进行了研究。研究人员将卵清蛋白(OVA)诱导的过敏性鼻炎小鼠模型用来评估参芪的抗过敏性鼻炎活性,并利用小鼠嗜碱性白血病(RBL-2H3)细胞来检测参芪对免疫球蛋白E调控的细胞脱粒的影响。研究人员通过分离脾脏淋巴球,并通过蛋白免疫印迹技术检测转录因子和ELISA技术检测细胞因
