在加拿大的肺动脉高血压 (PAH) 治疗selexipag的实际持续时间很低,平均持续时间为22个月. 没有发现明显的持续性预测因素,这表明需要进一步研究.
科学领域:
- 药理学 药理学是指药理学的学科.
- 现实世界的证据.
- 肺动脉高血压是肺动脉高血压.
背景情况:
- 在肺动脉高血压 (PAH) 中Selexipag的安全性和耐受性是在临床试验中确立的.
- 然而,加拿大缺乏关于selexipag持续性的真实数据.
- 之前的试验显示,多达14%的患者因不良事件而停止服用selexipag.
研究的目的:
- 在加拿大PAH患者中描述selexipag的短期和长期持续性.
- 在这个人群中识别selexipag持久性的预测因素.
主要方法:
- 成年PAH患者的回顾性分析,有选择西巴格的索赔 (2016年4月 - 2021年7月).
- 卡普兰-梅尔估计计算的持久性.
- 考克斯比例危险模型用于评估持久性预测因素.
主要成果:
- 包括311名PAH患者 (70%为女性,71%为50-79岁).
- 在6,12,24和36个月的持续率分别为76.1%,61.7%,48.3%和40.2%.
- 中位持续时间为22个月;没有发现显著的预测因素.
结论:
- 在加拿大的现实世界selexipag持久性似乎很低,与其他PAH疗法相比.
- 需要进一步的研究来确定预测因素和优化治疗结果.
