背景:许多哮喘患者表现出与痰嗜酸细胞增多症发作。嗜酸性粒细胞的Benralizumab目标绑定IL-5α受体,通过锁定细胞介导细胞毒性诱导细胞凋亡。目的:我们试图评估的安全benralizumab与嗜酸性成人哮喘和它的影响在气道粘膜嗜酸性粒细胞计数/粘膜下活检标本,痰,骨髓和外周血。方法:多中心、双盲、安慰剂对照研究的第一阶段中,13个受试者被随机分配到单剂量静脉注射安慰剂或1毫克/公斤benralizumab(第0天;组1),和14个受试者被随机分配到3月皮下剂量的安慰剂或100或200毫克的benralizumab(56天0,28日;队列2)。军团1和2是连续的。结果:组间不良事件的发生率相似。没有benralizumab相关的严重不良事件发生。队列1中静脉benralizumab产生一个从基线值降低61.9%的呼吸道粘膜嗜酸性粒细胞计数(28天;安慰剂:+ 19.6%; P = .28), as well as an 18.7% decrease (day 21) in sputum and a 100% decrease (day 28) in blood counts. Eosinophils were not detectable in bone marrow of benralizumab-treated subjects (day 28, n = 4). In cohort 2 subcutaneous benralizumab demonstrated a combined (100 + 200 mg) median reduction of 95.8% in airway eosinophil counts (day 84; placebo, 46.7%; P = .06), as well as an 89.9% decrease (day 28) in sputum and a 100% decrease (day 84) in blood counts. CONCLUSION: Single-dose intravenous and multiple-dose subcutaneous benralizumab reduced eosinophil counts in airway mucosa/submucosa and sputum and suppressed eosinophil counts in bone marrow and peripheral blood. The safety profile supports further development. Additional studies are needed to assess the clinical benefit in asthmatic patients.
