Abstract
本发明公开一种包含抗体‑结合蛋白配体已被共价固定于其上的多孔球形粒子的分离基质,其中所述配体的密度在10.5‑15 mg/ml的范围内和所述粒子的体积‑加权中位直径在30‑55μm的范围内。本发明还公开一种通过在色谱柱中使用所述分离基质的亲和色谱分离抗体的方法。
Description
本发明的技术领域
本发明涉及分离基质,且更特别地涉及可用于抗体分离的分离基质。本发明还涉及在基质上分离抗体的方法。
发明背景
在治疗性单克隆抗体(mAb)的制备中,在包含偶联的葡萄球菌(Staphylococcus)蛋白A(SpA)或SpA的变体的基质上的亲和色谱通常用作第一分离步骤,以除去大多数污染物。由于治疗性mAb的需求不断增加,对于提高分离过程的效率存在强大的驱动力,且几种方法正在评估中。
多柱连续色谱过程是可利用的,其中所述进料被施加于第一个柱,并且当第一个柱趋于饱和时则转移到一个或多个随后的柱中,在洗脱和再生随后的柱期间洗脱第一个柱并再生以再次加载。这样的过程可代表周期性反流色谱(PCC)或模拟移动床(SMB)并对分离治疗性mAb具有相当大的意义,见例如US7901581、US20130248451、US20130280788和US7220356,其通过引用以其整体结合到本文中。PCC/SMB过程可显著增加生产率,但似乎用目前可获得的分离基质(其被设计用于传统批量色谱)不能达到全部潜力。
因此,对专门设计用于连续色谱过程的新的分离基质和对使用这样的基质的方法存在着需求。

实施方案的详细描述
在一个方面,由图1-3所说明的,本发明公开一种包含多孔的、适当球形的、抗体-结合蛋白配体已被共价固定于其上的粒子的分离基质。这些配体的密度大于10 mg/ml,例如在10.5-15 mg/ml,例如10.5-12 mg/ml的范围内,和粒子的体积-加权中位直径在30-55 μm,例如45-55 μm或50-55 μm的范围内。配体的密度表示每毫升基质沉积体积中偶联的配体的含量,且其可例如通过氨基酸分析测定。体积加权中位直径,也指d50,v,可通过电臭氧感应(Coulter Counter)、激光衍射或显微镜与图像分析来测定。一种优选的方法是使用电臭氧感应与用所提及基质的狭窄筛分数校准的设备,对于其的d50,v已用显微镜和图像分析测定。
多孔粒子可包含交联多糖,其提供用于配体偶联的大的亲水表面,伴有在mAb或污染物和所述粒子之间的非特异性相互作用的最小风险。多糖适当地具有零或极低(例如< 5微摩尔/ml)含量的荷电基团以防止非特异性相互作用。交联增加刚度和化学稳定性并可通过本领域已知的方法,特别是通过环氧化物交联,使用例如表氯醇或双环氧化物作为交联剂实现。多糖的实例可以是葡聚糖、纤维素和琼脂糖。琼脂糖具有特殊的优点,即高度多孔的刚性凝胶可通过琼脂糖水溶液的热凝胶化获得。琼脂糖可合适地通过在US6602990、US7396467或US8309709中描述的方法交联,其通过引用以其整体结合到本文中。用这些方法交联的琼脂糖,所谓的高流量琼脂糖,具有高刚度和高孔隙度/孔隙体积的特别有利的组合,允许高流动速率和快速质量运输。高刚度对于具有小粒径的基质是特别重要的,允许高流动速率且无基质的坍塌。琼脂糖可例如在凝胶化之前用试剂(像烯丙基缩水甘油醚或烯丙基卤化物)烯丙基化,如在US6602990中所述。为允许高结合能力和快速质量运输,粒子可有利地具有可接近大分子种类(像IgG抗体)的大体积孔隙。这可如在“Handbook ofProcess Chromatography, A Guide to Optimization, Scale-Up and Validation”(1997) Academic Press, SanDiego, Gail Sofer & Lars Hagel eds. ISBN 0-12-654266-X, p. 368中所述,通过逆尺寸排阻色谱(SEC)测定。用于可接近的孔隙体积的合适参数是对定义大小的探针分子测定的凝胶相分配系数,KD。这是依据KD = (VR-V0)/(Vt-V0),从探针分子的保留体积VR、柱的间隙空位体积V0和柱的总液体体积Vt计算的柱-独立的变量。对于作为探针分子的分子量110 kDa的葡聚糖,多孔粒子可合适地具有在0.6-0.8,例如0.65-0.75或0.65-0.70的范围内的KD值。
配体可例如从抗体-结合细菌蛋白,例如SpA (蛋白A)、消化链球菌(Peptostreptococcus)蛋白L或链球菌(Streptococcus)蛋白G衍生。它们可结合于抗体,以致相互作用的KD值是至多1 x 10-6 M,例如至多1 x 10-7 M,例如至多5 x 10-8 M。它们可包含Fc-结合蛋白,例如SpA或/和SpA变体,其结合于IgG分子的Fc部分。它们可包含天然或突变蛋白A Fc-结合结构域的单体、二聚体或多聚体。天然蛋白A Fc-结合结构域E、D、A、B和C与突变的变体Z和Zvar一起示于图1中。在一些实施方案中,配体中的一个或多个结构域衍生自蛋白Z,或蛋白A的B或C结构域,其中在位置23的氨基酸残基为苏氨酸。这样的结构域具有为生物过程应用所需的改进的碱稳定性(见例如US8329860、US7834158、US 14/961164和WO2016079033,通过引用以其整体结合到本文中),其可例如通过于22 +/- 2℃,在0.5 MNaOH中孵育分离基质5 h来评估。合适地,然后基质保留至少90%或至少95%的孵育前原始IgG-结合能力。在某些实施方案中,一个或多个结构域包含如由SEQ ID NO: 8或9定义的氨基酸序列。SEQ ID NO:8是减去接头序列VDAKFD的Zvar结构域和SEQ ID NO:9是减去接头序列ADNKFN的C结构域。一个或多个结构域,例如全部结构域,还可通过一个或多个氨基酸取代、插入或缺失来突变。因此例如,在SEQ ID NO: 8或9内可存在至多10、9、8、7、6、5、4、3或2个突变,例如取代。

SEQ ID NO:9
KEQQ NAFYEILHLP NLTEEQRNGF IQSLKDDPSV SKEILAEAKK LNDAQAPK
配体可合适地在各结构域之间额外包含1-10个氨基酸残基的一个或多个接头序列,例如VDNKFN、ADNKFN、VDAKFD、AD或FN。此外,配体可包含偶联部分,例如在配体的C-末端或N-末端,合适地在C-末端的半胱氨酸或多个赖氨酸。配体还可包含在N-末端的前导序列,例如在信号肽和任选地还有接头序列的拷贝裂解后的斑痕(scar)或残基。这样的前导序列可例如是1-15个氨基酸(例如1-10个氨基酸)肽,例如AQ、AQGT、AQVDAKFD、AQGTVDAKFD或AQVDNKFN。因此,配体的典型结构可例如是前导序列 – (结构域-接头)n-1 – 结构域 – 偶联部分。n可例如是1-7,例如1、2、3、4、5、6或7。
在第二方面,由图4说明的,本发明公开一种包含如上所述的分离基质的色谱柱1。色谱柱可例如是轴向填充床柱1,其中基质粒子的圆柱形填充床2被限制在两个网状物/玻璃料3、4和两个分配器结构5、6之间,允许进料流通过入口7、入口分配器5和入口网状物/玻璃料3,穿过填充床2,然后通过出口玻璃料/网状物4、出口分配器6和出口8。填充床的高度h可例如是至多5 cm或至多10 cm,例如2-5 cm或2-4 cm。填充床的直径d可例如是至少1 cm,例如至少1.5 cm或1.5-200 cm、1.5-100 cm、1.5-50 cm或1.5-30 cm。
在第三方面,由图5说明的,本发明公开一种包含多个如上公开的色谱柱11、12、13的色谱系统10。系统可合适地被安排执行连续的色谱。它可例如包含至少两个,例如至少3个如上公开的色谱柱11、12、13,其填充有相同的分离基质并与一个或多个连接管道14、15、16连接,以致液体可从一个柱11、12流向随后的柱12、13和从最后的柱13流向第一个柱11,并且两个柱之间的各个连接管道可包含至少一个开/关阀17、18、19,其可以是三通阀或四通阀。该系统还可包含进料泵20,例如经由第一检测器21连接于第一个阀组件22。缓冲液泵23也可连接于该第一个阀组件22。第一个阀组件22还可经由第一个阀23连接于第一个柱11的入口。第一个柱11的出口端可通过第二检测器24连接于第二个阀17。第一个阀组件22还可经由第二个阀或阀组件25连接于第二个柱12的入口。第二个柱12的出口端可经由第三检测器26连接于阀18。此外,阀27可在阀17和阀18之间连接。阀27还可连接于阀28,其还连接于阀23和第二个阀组件25。由此来自第一个柱11的流出物可通过连接管道14、阀17、27、28和25导向第二柱12的入口。而且第一个阀组件22可经由阀29连接于第三个柱13的入口。第三个柱13的出口端可经由第四个检测器30连接于阀19。此外阀31可在阀18和阀19之间连接。阀31可还连接于阀32,后者还可连接于第二阀组件25和阀29。由此来自第二个柱12的流出物可通过连接管道15导入第三个柱13的入口。来自第三个柱13的流出物可经由阀19和23,通过连接管道16导入第一个柱11的入口。此外,第一、第二、第三和第四检测器21、24、26、30都可连接于测定单元32。测定单元可适合于使用来自检测器的检测信号以确定3个不同的柱的突破点和饱和点。测定单元32和所有的阀组件、阀和泵还可连接于控制单元33(所有的连接均未在图中示出),其适合于在从荷载区移除柱或向荷载区加入柱,改变流动速率,开始新的洗涤步骤等时,控制色谱系统。检测器21、24、26、30可例如是UV检测器。控制单元33可被配置以依据从测定单元32获得的突破点数据控制系统。或者,控制单元33可使用固定的预定步骤时间,以切换操作。
在第四方面,本发明公开一种通过亲和色谱分离抗体的方法。该方法包括以下步骤:
a) 输送过程进料穿过如上公开的至少第一色谱柱,以吸附来自进料的抗体。过程进料可例如包含至少4 mg/ml的抗体,例如4-15、4-10或4-5 mg/ml,和/或在这个步骤中的停留时间可例如少于2 min,例如0.3-1 min或0.3-0.8 min;
