欧洲药品管理局已受理 PTC Therapeutics旗下Translarna(ataluren)用于无义突变囊性纤维化(nmCF)的新适应症申请,用于未使用慢性吸入型氨基糖苷抗生素的患者。如果获得批准,Translarna将成为首款针对nmCF潜在病因的口服蛋白修复治疗药物。大约10%的囊性纤维化患者其疾病由无义突变导致,无义突变可导致最严重的囊性纤维化。
我们非常高兴将该药物的第二种适应症向前推进,这一适应症代表了实现 Translarna全部潜能的另一个里程碑,PTC Therapeutics首席执行官Peltz博士称。我们渴望将Translarna带给无义突变囊性纤维化患者,这些患者目前没有其它治疗选择用于他们疾病的潜在病因。我们期望与监管机构一起合作,帮助尽快将这一精准药物带给患者。
Translarna 在无义突变引起的遗传性疾病中能形成功能性蛋白
无义突变囊性纤维化是一种严重形式的囊性纤维化,其在治疗上非常具有挑战性。我们很高兴在不久将来可以有一种治疗选择用于nmCF患者,CF欧洲总裁 Noordhoek 称。正在取得的可以更好地理解与治疗囊性纤维化潜在遗传因素的进展是非常关键的,必须继续进行下去。」
Translarna 用于 nmCF的监管申请基于该公司之前宣布完成的双盲、安慰剂对照 3期研究的分析,该研究在nmCF患者中对Translarna与安慰剂进行了对比。PTC 正在进行一项额外的Translarna用于nmCF患者的随机、双盲、安慰剂对照 3期研究,预期今年底完成患者招募,关键结果有望2016年底获得。
Translarna是一种蛋白修复治疗药物,其旨在无义突变引起的遗传性疾病患者中使功能性蛋白得以形成。无义突变是遗传密码的一种改变,它提交中止了一种必需蛋白质的合成。由此导致的障碍由蛋白质不能完整地表达及不再有更长久的功能所决定。
