JAMA:卡那奴单抗可改善重症新冠肺炎住院患者预后

2021-07-21 MedSci原创 MedSci原创

对于重症新冠肺炎患者,IL-1β抑制剂卡那奴单抗可显著提高患者29天内无需机械通气存活率

重症新冠肺炎患者会出现急性呼吸窘迫综合征,全身性过度炎症是其主要特征,表现为过度的细胞因子释放和高炎症蛋白水平。地塞米松是一种具有广泛抗炎作用的糖皮质激素,对改善重症covid-19患者的预后有益。在 RECOVERY 研究中,研究人员证实IL-6抑制剂托珠单抗对改善缺氧和全身性炎症性重症新冠肺炎患者预后有益。IL-1β是包括IL-6在内的上游促炎细胞因子,参与了多种自身炎症疾病的发生。近日研究人员考察了IL-1β抑制剂卡那奴单抗(canakinumab)对重症COVID-19患者的疗效。

本次随机、双盲、安慰剂对照的III期试验在欧洲和美国的39家医院进行,共有454名新冠肺炎患者参与,患者因缺氧(不需要有创机械通气[IMV])、C反应蛋白或铁蛋白血浓度升高引起的全身性炎症住院,随机接受单次静脉输注卡那奴单抗(体重40-60 kg时,450 mg;体重60-80 kg时,600 mg;体重超过80 kg时,750 mg;n =227)或安慰剂(n=227)。研究的主要终点为3-29天内无IMV生存率,次要终点为COVID-19相关死亡率、全身炎症标志物和安全性。

患者平均年龄59岁,187名女性(41.2%),417名(91.9%)完成了29天的试验。在第3天到29天之间,卡那奴单抗组223名患者中有198名(88.8%)在不需要IMV的情况下存活,安慰剂组223名患者中有191名(85.7%),差异为3.1%,优势比为1.39。 卡那奴单抗组223例患者中有11例(4.9%)因COVID-19死亡,安慰剂组222例患者中有16例(7.2%),差异为-2.3%,风险比为0.67。卡那奴单抗组225名患者中有36人(16%)出现严重不良事件,而安慰剂组223名患者中有46人(20.6%)出现严重不良事件。

组间死亡及机械通气风险差异

研究认为,对于重症新冠肺炎患者,IL-1β抑制剂卡那奴单抗可显著提高患者29天内无需机械通气存活率。
