Lancet:新药Lomitapide有助治疗家族性高胆固醇血症

2012-11-07 Lancet Lancet

  11月2日,《柳叶刀》(Lancet)杂志在线发表了一项微粒体甘油三酯转移蛋白抑制剂Lomitapide治疗纯合子家族性高胆固醇血症(HoFH)的研究,结果表明,Lomitapide对于治疗HoFH有重要价值。   该研究为一项单盲、开放标签、临床Ⅲ期研究,HoFH患者从基线前6周开始当前的降脂治疗,并至少维持至第26周。Lomitapide的剂量根据安全性和耐受性逐渐从每天5 m

  11月2日,《柳叶刀》(Lancet)杂志在线发表了一项微粒体甘油三酯转移蛋白抑制剂Lomitapide治疗纯合子家族性高胆固醇血症(HoFH)的研究,结果表明,Lomitapide对于治疗HoFH有重要价值。

  该研究为一项单盲、开放标签、临床Ⅲ期研究,HoFH患者从基线前6周开始当前的降脂治疗,并至少维持至第26周。Lomitapide的剂量根据安全性和耐受性逐渐从每天5 mg递增至最大60 mg。研究的主要终点是低密度脂蛋白胆固醇(LDL-C)从基线到底26周的平均变化水平,之后患者继续使用Lomitapide治疗,直到第78周进行安全性评估。

  研究者从美国、加拿大、南非和意大利4个国家的11个中心共纳入29例年龄在18岁以上的HoFH患者,其中23例完成了26周的疗效试验和78周的完整试验。Lomitapide的中位剂量为40 mg/d。LDL-C从基线到底26周降低了50%。在第26周有8例患者的LDL-C水平低于2.6 mmol/L。在第56周和第78周,LDL-C水平仍分别下降了44%和38%。

  胃肠道症状是最常见的不良事件。4例患者转氨酶水平超过5倍正常值上限,减小剂量或暂时停药后恢复,没有患者因肝脏异常而停止治疗。
