Lancet Infect Dis:口服异戊二烯化抑制剂lonafarnib对慢性丁型肝炎患者疗效好

2015-07-17 崔倩 译 MedSci原创

目前的对于慢性丁型肝炎病毒(HDV)感染的治疗方法是不让人满意的。异戊二烯化会导致HDV和和抑制HDV的生成,在实验模型中的对异戊二烯化的废除是必不可少的过程。在概念验证的研究中,研究人员的目的是评估戊烯化抑制剂lonafarnib对慢性丁型肝炎患者的HDV RNA水平,安全性,以及耐受性的效果。    在这个2A阶段双盲,随机,安慰剂对照研究中,18岁及以上的慢性H

目前的对于慢性丁型肝炎病毒(HDV)感染的治疗方法是不让人满意的。异戊二烯化会导致HDV和和抑制HDV的生成,在实验模型中的对异戊二烯化的废除是必不可少的过程。在概念验证的研究中,研究人员的目的是评估戊烯化抑制剂lonafarnib对慢性丁型肝炎患者的HDV RNA水平,安全性,以及耐受性的效果。
    
在这个2A阶段双盲,随机,安慰剂对照研究中,18岁及以上的慢性HDV感染的患者被随机分配(组1中3:1和组2中2:1)接受lonafarnib 100毫克(组1)或lonafarnib 200毫克(第2组)治疗,每天两次共28天,并进行6个月的随访。参与者通过在四个无分层的组中的随机数表法进行随机分配的。

两组均招募了6名治疗参与者和2名安慰剂的参与者。第1组服用安慰剂的患者接受开放性的lonafarnib治疗,第2组也是。初级治疗终点是血清中HDV RNA病毒滴度的降低,主安全终点是参与者在完整4周时间中对药物处方剂量的耐受能力,其被定义为由于不耐受或3/4级不良事件而停药。
    
在2012年1月19日和2014年4月28日之间,共招募了14名患者参加此项研究,其中8例患者被分配到第1组,6例被分配到第2组。第28天时,与服用安慰剂患者相比,第1组和第2组的平均log HDV RNA水平从基线分别下降了-0.73logIU /mL(95%Cl 0.17-1.31;p=0.03)和-1.54logIU /mL(1.21-1.93,P<0.0001)。Lonafarnib血清浓度与HDV RNA变化相关(r2=0.78,P<0.0001)。模型拟合表明乙肝表面抗原(HBsAg)在短期药理延迟后保持稳定(0.75天[SE 0.24]),对于在阻断HDV生成中lonafarnib的有效性,第2组大于第1组(0.952 [SE 0.06] vs 0.739[0.05],P<0.001),HDV的半衰期为1.62天(0.07)。没有证据表明有病毒学耐药性。不良事件主要是组1患者出现3例患者轻度至中度的腹泻(50%),2例患者恶心(33%),第2组的所有患者(100%)都经历恶心,腹泻,腹胀,以及体重损失超过2千克(平均4千克)。在任何治疗组没有治疗停药发生。
    
lonafarnib治疗慢性HDV显著降低了病毒水平。病毒水平的显著下降与血清药物水平相关,并提供了进一步的证据表明其在慢性HDV感染中抑制异戊二烯化的效力。
