ESC 2017:CANTOS:卡纳单抗可通过减少炎症降低心血管疾病及肺癌的风险

2017-08-31 MedSci MedSci原创

CANTOS试验2旨在探究减少心脏病发作患者的炎症是否可降低其他心血管事件的发生风险。探究的药物为人类单克隆抗体——卡纳单抗,可中和白细胞介素-1β信号,从而抑制炎症。卡纳单抗常用于治疗与IL-1β过表达相关的罕见遗传性疾病。 该研究共纳入了10061例存在心脏病发作的患者,且C反应蛋白(hsCRP)水平升高。所有患者接受标准治疗,包括高剂量的他汀药物。此外,所有患者随机接受卡纳单抗50 m

CANTOS试验2旨在探究减少心脏病发作患者的炎症是否可降低其他心血管事件的发生风险。探究的药物为人类单克隆抗体——卡纳单抗,可中和白细胞介素-1β信号,从而抑制炎症。卡纳单抗常用于治疗与IL-1β过表达相关的罕见遗传性疾病。

该研究共纳入了10061例存在心脏病发作的患者,且C反应蛋白(hsCRP)水平升高。所有患者接受标准治疗,包括高剂量的他汀药物。此外,所有患者随机接受卡纳单抗50 mg、150 mg、300 mg或安慰剂治疗,每3个月给药一次。在300 mg卡纳单抗组,前两次给药间隔为2周,然后每3周给药一次。随访4年。

主要终点是非致死性卒中、非致死性卒中或心血管死亡的首次发生。次级终点是主要终点中的任何事件,或因不稳定心绞痛需要住院接受紧急血运重建。

结果显示,150 mg组和300 mg组患者心血管事件的风险分别降低15%和14%。50 mg、150 mg和300 mg组主要终点的HRs分别为0.93 (95% CI, 0.80–1.07; p=0.30)、0.85 (95% CI, 0.74–0.98; p=0.021)和0.86 (95% CI, 0.75–0.99; p=0.031)。

150 mg和300 mg组患者次级终点的发生风险降低了17%。50 mg、150 mg和300 mg组相应的HRs为0.90 (95% CI, 0.78–1.03; p=0.12)、0.83 (95% CI, 0.73–0.95; p=0.005)和0.83 (95% CI, 0.72–0.94; p=0.004)。

由于多样性测试,仅有150 mg组患者在主要和次级终点方便符合统计学差异。总体来说,卡纳单抗的使用是安全的,致命性感染的发生率约为1/1000。

探索性分析显示,卡纳单抗可显著降低总的癌症死亡率,尤其是肺癌的发生率及死亡率且效果呈剂量依赖性。

总之,该研究首次表明,降低胆固醇炎症可降低心血管的发生风险,使用卡纳单抗降低炎症或可显著改善某些高危患者的预后。
