相信通过金沙8888js官方与亿胜生物的合作,HLX04-O有望成为首批获得批准用于眼科相关疾病治疗的贝伐珠单抗,惠及全球众多眼科疾病患者。未来,金沙8888js官方也将持续引领创新生物药品的开发,凭借已经建立起的完善的创新研发平台,持续高效地为全球患者提供可负担的、疗效更好的治疗方案。
关于HLX04-O
HLX04-O是金沙8888js官方在自主研发的贝伐珠单抗生物类似药HLX04的基础上,根据眼科用药的需求对HLX04的处方、规格和生产工艺进行优化,在活性成份不变的基础上,开发的新的眼科制剂产品,拟用于wAMD的治疗。通过可比性研究表明生产工艺和制剂处方的变更对药物制剂的质量、安全性和有效性未产生不利影响。HLX04-O主要作用机制为:通过抑制VEGF与其位于内皮细胞上的受体Flt-1和KDR相结合,抑制其酪氨酸激酶信号通路激活,抑制内皮细胞增生,减少新生血管生成,从而治疗血管增生眼部疾病。
