Neurology:Pridopidine治疗亨廷顿病安全性和耐受性均较好

2013-03-09 高晓方 译 医学论坛网

  欧洲学者的一项研究表明,在亨廷顿病患者中pridopidine通常安全且耐受性良好。论文于2013年2月27日在线发表于《神经病学》(Neurology)。

  此项研究分为6个月随机对照试验(RCT)和6个月开放标签扩展试验(OLE)两个阶段。在OLE阶段,亨廷顿病患者接受4周pridopidine 45mg/天治疗后再接受22周90 mg/天治疗。对任何不良事件(AE)均加以记录。依据RCT治疗组(安慰剂、45 mg/天和90 mg/天组)对患者加以分类。

  结果显示,在386例完成RCT的患者中,353例进入OLE并有305例(86.4%)完成研究。在1年时,各治疗组报告AE≥1和AE≥1严重不良事件的患者百分比基本相似。两阶段研究中的AE分布基本相似;跌倒和舞蹈病恶化为最常见不良事件。在OLE期间,pridopidine组患者的AE≥1发生率高于安慰剂组。在RCT早期,pridopidine组患者心率轻度升高更为常见。在1年研究期间,未确认具有临床意义的实验室指标变化或EKG相关性安全隐患。
