药品介绍 Romark大药厂1月10日宣布已经在美国开始开发Alinia(硝唑尼特,nitazoxanide) 片的新适应症—慢性丙型肝炎。该公司已经向FDA提交了新药临床申请,并申请了快速审批资格。在美国开始的临床试验将首先评价硝唑尼特500mg,每日两次,给药24周对之前干扰素和利巴韦林联合治疗失败的病人的疗效。硝唑尼特是一类称为thiazolides化合物的第一个成员,该类化合物为小分子,通过抑制病毒结构蛋白的合成来阻断特定病毒的复制。研究表明硝唑尼特及其循环中的代谢产物tizoxanide,可以在低浓度时抑制细胞培养中的HBV和HCV。
一项II期、双盲、安慰剂对照临床试验已于2005年初在埃及的Romark消化病研究中心进行。病人是HCV基因型4型感染者,大约10%的病人之前经过PEG化干扰素+利巴韦林联合治疗而失败。这项试验考察口服硝唑尼特单独治疗对慢性丙肝的效果。对头20名病人阶段性分析表明,50%接受硝唑尼特治疗(500mg,每日2次)的病人在治疗24周末,HCV RNA水平达到检测水平以下,而安慰剂组的病人为0 (P=0.03)。药物耐受性良好,无明显不良反应,该试验仍在进行中。
Alinia已经在美国上市,但适应症是微小隐孢子虫(Cryptosporidium parvum,Cp)和蓝氏贾第鞭毛虫(Giardia lamblia)引起的腹泻。正在开发的其他适应症包括艰难梭状芽孢杆菌(Clostridium difficile)相关疾病、克隆氏病和慢性丙肝。硝唑尼特最初被开发为广谱抗肠道寄生虫药物和抗厌氧菌药物,和甲硝唑相比安全性更好。它也是第一个被证明对微小隐孢子虫引起的肠道疾病有效的药物。
基于硝唑尼特的抗病毒活性研究,Romark 公司于2005年初在埃及开始了一系列II期临床试验。
