Description
技术领域
本发明属于生物技术领域,具体涉及一种含有蛋氨酸为抗氧化剂的帕妥珠单抗的药物组合物。
背景技术
帕妥珠单抗是一种新型的抗HER2单克隆抗体,于2012年6月首次在美国上市,主要和曲妥珠单抗联用用于治疗HER2阳性的晚期转移性乳腺癌患者。通过结合HER2,帕妥珠单抗阻滞了HER2与其他受体的杂二聚,从而减缓了肿瘤的生长。
帕妥珠单抗属于人源化单抗,目前已上市的罗氏(Roche)为水针制剂,上市处方中含有帕妥珠单抗30mg/mL、120mM蔗糖、0.2mg/ml聚山梨酯80、20mM组氨酸-醋酸缓冲液,溶液pH 6.0。其中,处方中帕妥珠单抗为主药;蔗糖为稳定剂;聚山梨酯20为表面活性剂;组氨酸-醋酸为pH调节剂。
和大多数蛋白分子一样,帕妥珠单抗具有不稳定性,会经历多种化学和物理降解。和传统合成的小分子药物相比,生物分子具有复杂的结构,如一级、二级、三级等高级结构。而蛋白质的结构,特别是高级结构非常脆弱,容易发生结构变化,如变性(denaturation),聚集(aggregation)和沉淀(precipitation)。保持抗体的高级结构是发挥它们生物学活性的最基本要求。这些降解的产物会对生物制药的安全性产生很大的影响。特别是一些蛋白聚集物会激发人体的免疫反应,轻者会降低生物药物的疗效,重者甚至会造成病人的死亡。因此多聚体被认为是生物制药安全性的关键质量属性(critical quality attribute,CQA),直接影响到生物药的用药安全,这对于长期用药的产品如帕妥珠单抗尤为重要。抗体药物不仅仅需要在生产的时候能得到高纯度的产品,还要在运输、储存和使用过程中保持结构稳定。
因此,有必要开发一种新型帕妥珠单抗制剂以提高抗体的稳定性,从而提高产品质量的均一性和一致性,以及提高临床使用稳定性。

在优选的实施方案中,所述表面活性剂的浓度为0.01-5mg/ml,优选0.05-0.5mg/ml。
在一实施方案中,本发明的药物组合物进一步含有药学上可接受量的螯合剂,包括但不限于氨基多羧酸、羟基氨基羧酸、N-取代甘氨酸、柠檬酸、烟酰胺、去铁胺和去氧胆酸盐及其混合物,如乙二胺四乙酸(EDTA)、二乙三胺五乙酸(DTPA)、次氮基三乙酸(NTA)及它们的盐。本发明中使用的螯合剂可以是化合物的游离酸或者游离碱或者盐的形式存在,也可以是化合物或者相应盐的无水合物、水合物或者其它溶剂化物的形式存在。
在一实施方案中,本发明的药物组合物进一步含有药学上可接受量的防腐剂,包括但不限于间甲酚、苯酚、苯甲醇、苯扎氯铵、苯氧乙醇或对羟基苯甲酸甲酯。
在优选的实施方案中,本发明所述的药物组合物含有以下的成分:
其中,pH为5.0-6.0。

在一实施方案中,本发明的药物组合物可以不需要额外添加张力剂,这样的张力剂例如氯化钠、氯化钾等,减少了辅料的种类。
在一实施方案中,本发明组合物仅含有帕妥珠单抗一种蛋白质,以避免两种或两种以上蛋白之间互相影响导致的潜在的稳定性风险。
发明人经过大量的实验和数据筛选发现,当本发明制剂中蛋氨酸的浓度低于5mM时,蛋氨酸提高组合物稳定性的能力受到明显限制,当蛋氨酸的浓度高于40mM时,大于已上市抗体药物的常规用量,当蛋氨酸浓度在5-40mM时,能显著提高帕妥珠单抗组合物的物理和化学稳定性。
在本发明中,发明人经过了深入的研究,对各组分以及含量进行了大量的筛选,获得了稳定性更好的本发明的药物组合物,例如,对缓冲液进行了筛选,确定了在磷酸盐/磷酸、组氨酸-醋酸盐、组氨酸-盐酸中有较好的物理和化学稳定性,其中组氨酸-醋酸盐与组氨酸-盐酸效果相当,优于磷酸盐/磷酸;对稳定剂进行了筛选,确定了在蔗糖、海藻糖和盐酸精氨酸中均有较好的稳定性,其中在盐酸精氨酸中稳定性更好。
在另一方面,本发明还涉及用于制备治疗HER2阳性的肿瘤的药物的用途,优选地,所述HER2阳性的肿瘤为乳腺癌或胃癌。
本发明的有益效果为:
本发明所述组合物不仅在外观、可见异物上等有较好的效果(均为无色澄明液体且无异物),而且其物理稳定性和化学稳定性均有很大程度的提高,具有非常广阔的市场应用前景。

上述结果表明,在以不同含量聚山梨酯20及聚山梨酯80作为表面活性剂的帕妥珠单抗组合物中,其多聚体含量均较低,IEC-HPLC主峰纯度均较高,说明相应帕妥珠单抗组合物的物理稳定性和化学稳定性均较好。
实施例6.不同稳定剂对帕妥珠单抗组合物稳定性的影响
对比了不同稳定剂对帕妥珠单抗组合物的稳定性的影响。制剂18和19(水针制剂)均含有30mg/ml帕妥珠单抗、0.2mg/ml的聚山梨酯20,pH为6.0。各制剂辅料用量见表11。
表11.不同稳定剂的帕妥珠单抗组合物
影响因素试验方案
将上述处方分别进行高温和光照破坏试验。
高温试验:将样品置于40℃±2℃恒温箱中,于第2周取样检测;
光照试验:将样品放置于光照箱(25℃±3℃,4500Lx±500Lx)中10天后取样。
将经过上述影响因素试验的样品进行外观、可见异物、SEC-HPLC和IEC-HPLC纯度检测。结果见表12。
表12.各个制剂经过高温和光照破坏后帕妥珠单抗外观/可见异物、聚合物含量和IEC-HPLC主峰纯度
*试验数据为平均值±标准偏差,重复3次。
上述结果表明,经过高温和光照后,蔗糖和盐酸精氨酸为稳定剂的本发明所述的帕妥珠单抗组合物的多聚体含量均较低,IEC-HPLC主峰纯度均较高,说明组合物的物理稳定性和化学稳定性均较好,其中,相较于蔗糖为稳定剂的本发明的帕妥珠单抗制剂,盐酸精氨酸为稳定剂的本发明的帕妥珠单抗制剂化学稳定性更优(IEC-HPLC主峰纯度更高,尤其是光照破坏后),物理稳定性相当。
总结
发明人经过广泛深入的研究发现,特定浓度的蛋氨酸与帕妥珠单抗、稳定剂(例蔗糖/盐酸精氨酸/海藻糖)、缓冲剂(例组氨酸-盐酸、组氨酸-醋酸、磷酸/磷酸盐)、表面活性剂(例聚山梨酯20或80)组成的药物组合物在pH为5.0-6.8的条件下,具有较优的物理和/或化学稳定性,特别是在3-30mg/ml帕妥珠单抗,20-40mM的蛋氨酸、115-125mM蔗糖或海藻糖或盐酸精氨酸,15-25mM组氨酸-盐酸组氨酸或组氨酸-醋酸缓冲液,pH5.0-6.0,0.05-0.5mg/ml聚山梨酯20等条件下,帕妥珠单抗组合物在高温和光照条件下的物理和/或化学稳定性更优。
本领域技术人员会清楚,可以进行本发明的许多修改和变化而不背离其精神和范围。本文所述的具体实施方案仅通过实例的方式提供,并不意味着以任何方式限制。本发明的真正范围和精神通过所附权利要求书示出,说明书和实施例仅是示例性的。
