GW Pharma公司的大麻提取物大麻二酚(Epidiolex)很可能在美国批准用于治疗两种罕见且难治的儿童型发作性癫痫:Lennox-Gastaut综合症(LGS)和Dravet综合征(DS)相关的癫痫发作。

GW Pharma公司的大麻提取物大麻二酚(Epidiolex)很可能在美国批准用于治疗两种罕见且难治的儿童型发作性癫痫:Lennox-Gastaut综合症(LGS)和Dravet综合征(DS)相关的癫痫发作。

今天FDA召开的公众咨询委员会会议发布:“根据临床数据进行的风险和收益分析,Epidiolex很可能被批准上市。一般来说,与Epidiolex治疗相关的风险都是可接受的,主要是考虑到LGS和DS的致命性以及Epidiolex的临床有效性。”由于没有重要的安全性或有效性问题, FDA外周和中枢神经系统药物咨询委员会将推荐该药物的批准。预计到今年6月底,监管机构将做出最终决定。

Epidiolex目前正在美国和欧盟进行审查,包含三项III期临床试验,数据显示Epidiolex可以减少DS和LGS患者的月发作率。服用Epidiolex的LGS患者每月癫痫发作的中位数下降高达42%,而安慰剂仅下降17%。在DS患儿的研究中,与服用安慰剂组相比,服用该药物的患者中有5%的患者无癫痫发作,患者的惊厥性癫痫发作的中位数减少39%明显高于安慰剂组下降的13%。

据报道,GW正在与药物管制局协商,确保它可以合法销售大麻药物,尽管它只含有不到0.1%的四氢大麻酚。
