FDA评估多发性硬化新药Gilenya心血管安全性

2012-05-19 陈蓉 爱唯医学网

       2012年5月14日,美国食品药品管理局(FDA)宣布,已评估了1例患者使用首剂多发性硬化治疗药Gilenya(芬戈莫德)后死亡的报告。该机构还评估了Gilenya临床试验和上市后的其他数据,包括死于心血管事件或死因不明患者的报告。目前,FDA还不能确定使用Gilenya是否与这些死亡有关。   &

       2012年5月14日,美国食品药品管理局(FDA)宣布,已评估了1例患者使用首剂多发性硬化治疗药Gilenya(芬戈莫德)后死亡的报告。该机构还评估了Gilenya临床试验和上市后的其他数据,包括死于心血管事件或死因不明患者的报告。目前,FDA还不能确定使用Gilenya是否与这些死亡有关。

       然而,FDA仍然对Gilenya首次给药后的心血管效应表示关切。数据显示,尽管Gilenya降低最大心率的效应通常出现在首次给药后6 h以内,但对于部分患者而言,最大效应可能延迟至首次给药后20 h才会出现。因此,现已将已有或曾有(6个月内)特定心脏问题或卒中,或正在服用特定抗心律失常药物的患者,列为Gilenya的禁忌人群。已对Gilenya标签进行了相应修订。

       FDA仍然建议,对使用Gilenya的所有患者,在首次给药后至少6 h内监测心动过缓征象。此外,还建议对所有开始接受Gilenya治疗的患者每小时测定脉搏和血压。给药前和观察期结束时应做心电图检查。应持续进行心血管监测直至所有症状缓解。

       不仅如此,FDA目前还建议,对于心动过缓高危患者或可能难以耐受心动过缓的患者,应将心血管监测的时间延长至6 h以上。延长期监测应包括整晚持续心电图监测。高危患者包括:


◆在首次使用Gilenya后出现严重心动过缓的患者;

◆有特定既有疾病而可能难以耐受心动过缓的患者;

◆同时使用其他减慢心率或房室传导的药物的患者;

◆在开始使用Gilenya之前或在心血管监测期间有QT间期延长的患者;

◆同时使用其他延长QT间期和可导致尖端扭转型室性心动过速的药物的患者。


        FDA将及时通报有关Gilenya心血管安全性的最新信息。
