科学领域:
- 心血管医学 心血管医学
- 药理学 药理学是指药理学的学科.
- 血液学 血液学 血液学
背景情况:
- 阿贝拉西马布是一种单克隆抗体,向不活跃的XI因子,抑制其激活.
- 在心房动中,abelacimab与直接口服抗凝剂的比较安全性尚未得到充分证实.
研究的目的:
- 评估abelacimab与rivaroxaban相比的安全性和有效性,在中度至高风险的心房动患者中.
- 作为主要终点,评估重大或临床相关的非重大出血的发生率.
主要方法:
- 一项随机对照试验,涉及1287名心房的患者.
- 患者接受皮下abelacimab (每月150毫克或90毫克) 或口服里瓦罗克萨班 (每天20毫克).
- 主要结局是重大或临床相关的非重大出血的发生率.
主要成果:
