智通财经APP获悉，GSK(GSK.US)宣布，美国FDA已受理其在研疗法depemokimab用于两项适应症的生物制品许可申请。包括作为附加维持疗法，用以治疗12岁及以上具2型炎症特征(以血液嗜酸性粒细胞计数为标志)的成人和青少年哮喘患者，这些患者接受中至高剂量吸入性皮质类固醇(ICS)联合另一种哮喘控制药物治疗；以及作为附加维持疗法，用以治疗伴有鼻息肉的慢性鼻窦炎(CRSwNP)成人患者，这些患者的病情控制不佳。该申请的PDUFA日期为2025年12月16日。
根据新闻稿，如果获批，depemokimab将成为仅须每6个月给药一次的首个获批超长效生物制品。值得一提的是，该疗法曾获行业媒体Evaluate评估为有望在2025年获批上市的潜在重磅疗法!
Depemokimab是一款在研白细胞介素-5(IL-5)靶向的超长效生物制品。Depemokimab能够与IL-5以高亲和力结合，以每六个月给药一次的频率用以治疗重度哮喘患者。IL-5是2型炎症中的关键细胞因子。超过80%的严重哮喘患者的病情是由2型炎症引起的，患者具有嗜酸性粒细胞水平升高特征，且其病情恶化不可预测。
