Description
技术领域
本发明涉及生物技术领域,具体地,本发明涉及BCMA抗体及其应用,更具体地,本发明涉及能够特异性识别BCMA抗体或其抗原结合片段、核酸分子、表达载体、重组细胞、嵌合抗原受体、CART细胞、药物组合物、制药用途以及检测BCMA的试剂盒。
背景技术
多发性骨髓瘤(MM)是常见的恶性血液病,占所有癌症死亡例的2%,据Globaldata 2019年统计,2017年全球发病人数为353890人,预计20127年将达到555243例,其主要病状是:骨髓中的浆细胞无限增殖,进而导致骨坏死。目前对于该病的治疗方案主要为对症治疗、化疗、放疗和干细胞移植,但将近100%的复发率让对该病的治疗变得极为艰难。
BCMA(B-cell maturation antigen,B细胞成熟抗原)是TNF超家族受体成员(TNFRSF17,III型跨膜蛋白,全长185个氨基酸,胞外段54个氨基酸)。BCMA特异性高表达于浆细胞和多发性骨髓瘤细胞表面;并且记忆B细胞,造血干细胞和其他正常组织细胞中均不表达。其功能与同家族受体TACI、BAFFR以及配体APRIL/BAFF一起调节B细胞的活化,分化以及转化成浆细胞和延长浆细胞寿命。B细胞分化成浆细胞过程中,细胞表面BCMA表达上调,缺乏BCMA的小鼠有正常数量的B细胞健康且外观正常,但浆细胞的生存周期缩短。
目前对于多发性骨髓瘤患者的治疗,效果差,成本高,周期长。BCMA因其特异性高表达于浆细胞和骨髓瘤细胞的表面,所以BCMA是治疗多发性骨髓瘤非常理想的靶点。现有的临床结果显示对于多发性骨髓瘤患者的免疫细胞治疗明显优于化疗和放疗,但是在使用鼠源抗体进行人体治疗时,鼠源抗体的异质性会引起人抗鼠抗体反应(Human anti-mouseantibody reaction,HAMA),导致抗体半衰期短,在人循环系统中被很快清除,失去疗效。而人源化抗体可以大大减少异源抗体对人类机体造成的免疫副反应,因此,抗体的人源化修饰以提高抗体的人源化程度、减弱HAMA显得至关重要。
鉴于此,本领域急需靶向BCMA的人源化抗体。

此外,术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中,“多个”的含义是至少两个,例如两个,三个等,除非另有明确具体的限定。
抗体
本文中,术语“抗体”是能够与特异性抗原结合的免疫球蛋白分子。包括两条分子量较轻的轻链和两条分子量较重的重链,重链(H链)和轻链(L链)由二硫键连接形成一个四肽链分子。其中,肽链的氨基端(N端)氨基酸序列变化很大,称为可变区(V区),羧基端(C端)相对稳定,变化很小,称为恒定区(C区)。L链和H链的V区分别称为VL和VH。
在可变区中某些区域氨基酸组成和排列顺序具有更高的变化程度,称为高变区(Hypervariable region,HVR),高变区为抗原和抗体结合的位置,因此也称为决定簇互补区(complementarity-determining region,CDR)。重链可变区和轻链可变区上均有三个CDR区。重链可变区和轻链可变区的除CDR之外的区域被称为框架区。
本发明利用BCMA胞外段,通过免疫获得了高特异性的高亲和力的抗BCMA的Fab(antigen-binding fragment)抗体片段。利用该抗体片段能够与BCMA抗原特异性结合,从而可以靶向性治疗肿瘤等疾病。同时,发明人对所获得的抗体片段进行人源化筛选,发现在重链可变区和轻链可变的框架区的某些位点进行突变后,获得抗体的人源化程度大幅提高,且不影响抗体与抗原的特异性结合。
在一些实施方案中,本发明提供了一种能够特异性识别BCMA的抗体或者抗原结合片段,所述抗体包括重链可变区和轻链可变区,其中,所述重链可变区的框架区与SEQ IDNO:1相比,具有选自下列的至少一种突变:c.1E>Q,c.5Q>V,c.9P>A,c.11L>V,c.12I>K,c.20M>V,c.38K>R,c.40K>A,c.44G>R,c.48I>M,c.50Y>W,c.61N>S,c.62E>Q,c.65K>Q,c.67K>R,c.68A>V,c.70L>I,c.72S>R,c.74K>T,c.76S>A,c.87T>R,c.91S>T;所述重链可变区的CDR具有SEQ ID NO:3~5所示的氨基酸序列或与SEQ ID NO:3~5所示的氨基酸序列具有至少95%同一性的氨基酸序列;所述轻链可变区的框架区与SEQ ID NO:2相比,具有选自下列的至少一种突变:c.2V>I,c.7P>S,c.12L>P,c.15L>P,c.17D>Q,c.24R>K,c.39H>Y,c.50K>Q,c.88L>V,c.92F>Y,c.94S>M;所述轻链可变区的CDR具有SEQ ID NO:6~8所示的氨基酸序列或与SEQ ID NO:6~8所示的氨基酸序列具有至少95%同一性的氨基酸序列。其中,“c.1”代表在序列中的位置,例如“c.1E>Q”是指所述序列的第一个氨基酸由“E”突变为“Q”,“c.2V>I”是指所述序列的第2个氨基酸由“V”突变为“I”。
另一些实施方案中,本发明所提供的抗体或者抗原结合片段与上述重链可变区的CDR和轻链可变区的CDR相比,具有保守氨基酸取代。“抗原结合片段”是指保持特异性结合抗原能力的抗体片段。“保守氨基酸取代”指的是氨基酸被另一氨基酸发生生物学上、化学上或者结构上相似的残基所取代。生物学上相似的指的是该取代不破坏BCMA抗体或者与BCMA抗原的生物学活性。结构上相似指的是氨基酸具有相似长度的侧链,如丙氨酸、甘氨酸或丝氨酸,或具有相似大小的侧链。化学相似性指的是氨基酸具有相同的荷电或者都是亲水或者疏水的。例如疏水残基异亮氨酸、缬氨酸、亮氨酸或者甲硫氨酸相互取代。或者极性氨基酸相互取代,例如用精氨酸取代赖氨酸、谷氨酸取代天冬氨酸、谷氨酰胺取代天冬酰胺,丝氨酸取代苏氨酸等等。
在一些实施方案中,本发明提供了一种抗体或抗原结合片段,所述抗体或抗原结合片段具有SEQ ID NO:9~10任一项所示氨基酸序列的重链可变区和具有如SEQ ID NO:11~13任一项所示氨基酸序列的轻链可变区。发明人通过抗体序列比对数据库(NCBI、IMGT)可得到上述抗重链可变区序列的CDR区(如SEQ ID NO:3~5所示)和轻链可变区序列的CDR区(如SEQ ID NO:6~8所示)。在另一些实施方案中,所述抗体或抗原结合片段的重链可变区序列与SEQ ID NO:9~10所示氨基酸序列相比,具有保守氨基酸取代。在一些实施方案中,所述抗体或抗原结合片段的轻链可变区序列与SEQ ID NO:11~13任一项所示氨基酸序列相比,具有保守氨基酸取代。当然,这些保守氨基酸取代不会对抗体或者抗原结合片段的生物学功能带来改变。在一些具体方式中,这些保守氨基酸取代可以发生在重链可变区和轻链可变区中除了CDR区之外的氨基酸上。
在一些优选方案中,本发明提供了一种抗BCMA单链抗体,该抗体通过连接肽将前面所述的重链可变区和轻链可变区连接,获得特异性靶向结合BCMA的单链抗体,所述连接肽为常规制备单链抗体常用连接肽或经过改造后性能更优的连接肽。
核酸分子、表达载体、重组细胞
在制备或者获取这些抗体的过程中,可以利用表达这些抗体的核酸分子,与不同的载体连接,然后在不同细胞中表达,来获得相应抗体。
为此,本发明还提供了一种分离的核酸分子,所述核酸分子编码上述所述的抗体或抗原结合片段。
在一些实施方案中,所述分离核酸分子具有如SEQ ID NO:20~24任一项所示核苷酸序列或具有SEQ ID NO:25~30任一项所示核苷酸序列。
在一些实施方案中,所述分离的核酸分子与上述SEQ ID NO:20~24所示的核苷酸序列至少具有90%以上的同源性,优选具有95%以上的同源性,更优选具有98%、99%以上的同源性。在至少一些实施方案中,所述分离的多核苷酸与所述SEQ ID NO:25~30所示的核苷酸序列至少具有90%以上的同源性,优选具有95%以上的同源性,更优选具有98%、99%以上的同源性。这些与SEQ ID NO:20~24或者SEQ ID NO:25~30具有同源性的序列,能够表达与SEQ ID NO:9~13和SEQ ID NO:14~19相似的氨基酸序列,从而能够与BCMA抗原特异性结合,实现抗体的靶向性功能。
本发明还提供了一种表达载体,所述表达载体包含上述分离的核酸分子。在将上述分离的多核苷酸连接到载体上时,可以将多核苷酸与载体上的控制元件直接或者间接相连,只要这些控制元件能够控制多核苷酸的翻译和表达等即可。当然这些控制元件可以直接来自于载体本身,也可以是外源性的,即并非来自于载体本身。当然,多核苷酸与控制元件进行可操作地连接即可。本文中“可操作地连接”是指将外源基因连接到载体上,使得载体内的控制元件,例如转录控制序列和翻译控制序列等等,能够发挥其预期的调节外源基因的转录和翻译的功能。当然用来编码抗体重链和轻链的多核苷酸,可以分别独立的插入到不同的载体上,常见的是插入到同一载体上。常用的载体例如可以为质粒、噬菌体等等。例如Plasmid-X质粒。
本发明还提供了一种重组细胞,该重组细胞中包含有该表达载体。可以将表达载体导入到哺乳动物细胞中,构建获得重组细胞,然后利用这些重组细胞表达本发明提供的抗体或者抗原结合片段。通过该重组细胞进行培养,即可以获得相应抗体。这些可用的哺乳动物细胞例如可以为CHO细胞等。
嵌合抗原受体、CAR T细胞
本发明涉及嵌合抗原受体(CAR),CAR是结合基于抗体的针对期望的抗原(例如,肿瘤抗原)的特异性与T细胞受体-激活细胞内结构域以产生展示特异性抗肿瘤细胞免疫活性的嵌合蛋白的分子。
表达CAR的T细胞被称为CAR T细胞或CAR修饰的T细胞。
在一个实施方式中,本发明的CAR包括具有抗原识别结构域的胞外区、跨膜区和胞内区。
本发明的实施方案的CAR(包括其功能部分和功能变体)可通过本领域已知的方法获得。CAR可以通过制备多肽或蛋白质的任何合适的方法制备。从头合成多肽和蛋白质的合适的方法描述在参考文献,如Chan等,Fmoc Solid Phase Peptide Synthesis,OxfordUniversity Press,Oxford,United Kingdom,2000;Peptide and Protein DrugAnalysis,Reid,R.编辑,Marcel Dekker Inc.,2000;Epitope Mapping,Westwood等编辑,OxfordUniversity Press,Oxford,United Kingdom,2001;和美国专利5,449,752中。另外,多肽和蛋白质可利用标准的重组方法使用本文描述的核酸重组产生。参见,例如,Sambrook等,Molecular Cloning:A Laboratory Manual,第3版,Cold Spring HarborPress,ColdSpring Harbor,NY 2001;和Ausubel等,Current Protocols in MolecularBiology,Greene Publishing Associates以及John Wiley&Sons,NY,1994。此外,本发明的一些CAR(包括其功能部分和功能变体)可分离自和/或纯化自诸如植物,细菌,昆虫,哺乳动物如大鼠、人等的来源。分离和纯化方法为本领域熟知的。可选地,本文描述的CAR(包括其功能部分和功能变体)可通过诸如Synpep(Dublin,CA)、Peptide TechnologiesCorp.(Gaithersburg,MD)和Multiple Peptide Systems(San Diego,CA)的公司商业合成。在这方面,可合成、重组、分离和/或纯化本发明的CAR。

功能变体可,例如,包含具有至少一个保守性氨基酸置换的亲本CAR的氨基酸序列。替代地或另外地,功能变体可包含具有至少一个非保守性氨基酸置换的亲本CAR的氨基酸序列。在这种情况下,优选的是不会干扰或抑制功能变体的生物活性的非保守性氨基酸置换。非保守性氨基酸置换可以增强功能变体的生物活性,使得功能变体的生物活性与亲本CAR相比有所增加。
本发明CAR的氨基酸置换优选为保守性氨基酸置换。保守性氨基酸置换为本领域已知的,并且包括其中具有某些物理和/或化学性质的一个氨基酸被交换为具有相同或类似化学或物理性质的另一氨基酸的氨基酸置换。例如,保守性氨基酸置换可为将酸性/带负电荷的极性氨基酸置换为另一酸性/带负电荷的极性氨基酸(如,Asp或Glu)、具有非极性侧链的氨基酸置换为具有非极性侧链的另一氨基酸(如,Ala、Gly、Val、He、Leu、Met、Phe、Pro、Tip、Cys、Val等)、碱性/带正电荷的极性氨基酸置换为另一碱性/带正电荷的极性氨基酸(如Lys、His、Arg等)、具有极性侧链的不带电荷的氨基酸置换为具有极性侧链的另一不带电荷的氨基酸(如,Asn、Gln、Ser、Thr、Tyr等)、具有β分支侧链的氨基酸置换为具有β分支侧链的另一氨基酸(如,Ile、Thr和Val)、具有芳族侧链的氨基酸置换为具有芳族侧链的另一氨基酸(如,His、Phe、Trp和Tyr)等。

实施例2 BCMA人源化抗体评价
1)人源化BCMA抗体亲和力检测
通过ELISA、Fortebio和FACs三种方式检测4个BCMA人源化抗体(hu VH1-VL1;huVH2-VL1;hu VH1-VL2;huVH1-VL3)针对BCMA抗原的亲和力,具体方法如下:
抗体亲和力ELISA检测:将hu(人)BCMA ECD His,ACRO,BCA-H522y包被在96孔酶联包被板中,浓度为2μg/mL,100μL/孔,将4个人源化抗体分别用1%BSA配制成起始浓度20μg/mL,1%BSA 3倍梯度稀释(前一梯度抗体浓度为后一梯度抗体浓度的3倍),抗体与抗原结合,检测4个抗体的EC50值(具体操作步骤为一般ELISA操作步骤)。其中mVH-mVL为鼠源BCMA抗体,是人源化之前的鼠源抗体,结果如下图1所示,结果显示4个人源化BCMA抗体与鼠源BCMA抗体mVH-mVL具有处于同一水平的EC50,并且huVH1-VL2亲和力最高。
抗体亲和力Fortebio检测,利用带AMC biosensor(Pall,lot:1907292)先Loadingh BCMA ECD mFc3ug/mL,然后分别结合4种人源化抗体,分别检测4种抗体的KD,Kon和Kdis。具体操作步骤为使用Fortebio仪器(forteBio,Serial NO:FB-40476)的常规操作。检测结果如下图2所示,说明4个BCMA人源化抗体与抗原的亲和力较强并且和鼠源BCMA抗体mVH-mVL处于同一水平,huVH1-VL2亲和力最高。
FACs检测抗体与肿瘤细胞系的结合:
K562细胞(CCL-243TM)为人慢性髓系白血病细胞,CHO细胞(CRL-12023TM)为中国仓鼠卵巢细胞,分别将含有人BCMA全长序列的慢病毒(含目的基因的载体序列见SEQ ID NO:31)感染K562细胞和CHO细胞,感染后挑单克隆,获得稳定表达BCMA的K562-BCMA细胞株和CHO-BCMA细胞株,检测4人源化抗体分别与K562-BCMA和CHO-BCMA的亲和力(EC50),具体检测方法如下:收获细胞,PBS洗涤1次,然后用PBS按照2E+5cells/200μL将细胞重悬。将4种BCMA人源化抗体用1%BSA 3倍梯度稀释,前一梯度抗体浓度为后一梯度抗体浓度的3倍,(抗体起始浓度为30μg/ml,共11个梯度)后分别与细胞4℃孵育30min。其后与APC anti-human IgG Fc Antibody(Biolegend,409306)4℃孵育30min,1×PBS洗涤2次,Beckman Coulter(型号:CytoFLEX)流式细胞仪检测。如下图3所示,3个人源化抗体与K562-BCMA细胞和CHO-BCMA细胞有浓度梯度依赖的结合并且EC50与鼠源BCMA抗体处于同一水平,huVH1VL2与K562-BCMA亲和力EC50稍弱一些,但huVH1-VL2与CHO-BCMA亲和力EC50与其它3个人源化抗体处于同一水平,4个人源化抗体和鼠源BCMA抗体与CHO-BCMA结合表达丰度上,从高到低的顺序为m VH-m VL,hu VH1-VL1,hu VH2-VL1,hu VH1-VL2,hu VH1-VL3。
2)4个人源化BCMA抗体与BCMA配体APRIL竞争性结合实验:
购买ACRO重组人APRIL Ala-Leu 250+N端His标签(Human APRIL/TNFSF13Protein,His Tag货号APL-H5244)。将hBCMA-mFc以4μg/ml包被于ELISA板中,4℃包被过夜。1×PBS洗涤1次后,用1%BSA(Sangon Biotech,A500023-0100)封闭1h,然后再用1×PBS洗涤1次。将4个人源化抗体3倍梯度稀释,前一梯度抗体浓度为后一梯度抗体浓度的3倍,起始浓度为100μg/ml,共11个梯度,稀释液用h APRIL His 0.2μg/ml,(此浓度在APRIL与hBCMA-mFc结合的EC50和饱和之间),h APRIL His用1%BSA溶解,37℃孵育30min,1×PBS洗涤5次,加入1:1500稀释的HRP标记的抗His抗体(Anti-his tag HRP,Biolegend,652504),37℃孵育30min,洗涤5次,TMB显色,终止后多功能酶标仪读数。结果如下图4所示,4个人源化BCMA抗体阻断APRIL的IC50与鼠源BCMA抗体m VH-m VL相当,并且4个人源化BCMA抗体对APRIL与hBCMA-mFc的阻断效果明显且呈浓度梯度依赖性。
3)4个人源化BCMA抗体特异性
对4个人源化BCMA抗体进行特异性流式检测,将4个人源化BCMA抗体10ug/ml100ul分别与K562,K562-BCMA,CHO,CHO-BCMA和K562-BCMA细胞于4℃孵育30min,之后用1×PBS洗涤2次,之后加入APC anti-human IgG Fc Antibody(Biolegend,409306)于4℃孵育30min,之后用1×PBS洗涤2次。然后利用Beckman Coulter流式细胞仪进行检测。检测结果如下图5所示,4个人源化BCMA抗体能够特异性地结合BCMA表达阳性的细胞。

a接种293T细胞5E6于10cm细胞培养皿中,加入10mL含10%FBS的DMEM培养基(DMEMGibco,11995040-1L;FBS Gibco,10091-148),5%CO2,37℃条件下CO2培养箱中培养24h;
b慢病毒包装体系
c包装后48h收细胞上清,25000rpm超速离心后检测慢病毒滴度,检测方法如下:将收集的慢病毒原液梯度体积同样条件下感染293T细胞,48h后流式检测293T细胞GFP阳性率百分比,根据计算公式原液滴度(TU/mL)=1.5×10E+05×293T细胞GFP阳性率百分比/慢病毒原液体积μl×1000来计算慢病毒原液滴度。
2)CART细胞制备
Ficoll淋巴分离液(达科为,AS1114546)从血液(志愿者献血50mL)中分离PBMC细胞,偶联CD3/CD28抗体的磁珠正选法分离获得T细胞,将慢病毒按MOI=5:1感染T细胞以制备CART细胞,CART细胞培养7天后通过检测CART细胞的GFP阳性率来确定CART细胞CAR阳性率,如图9所示,
3)CART细胞体外功能评价
分别取4种靶细胞K562,K562-BCMA,RPMI8226各2×10E+06个细胞,先利用CytoCalceinTM Violet550对靶细胞进行染色,1×10E+05细胞/100ul/孔。将效应细胞(CAR+CART,T细胞为对照)分别与上述靶细胞按照0.25:1、1:1、5:1及10:1的比率加入96孔板中混匀,终体积200ul。培养6h后,将细胞混匀离心。上清利用Human IL-2ELISA检测试剂盒(invitrogen,REF 88-7025-88)Human IFN gamma ELISA试剂盒(invitrogen,REF 88-7316-88)检测各孔中IL-2及IFN-γ浓度,沉淀部分用100ul Annexin V Binding Buffer(Biolegend,B274722)重悬,300g离心5min,之后添加3ul APC-Annexin V(Biolegend,Cat640920)和1.5ul PI染料(Biolegend,Cat 421301),避光孵育15min,添加100ulAnnexin V Binding Buffer重悬,之后利用Beckman Coulter流式细胞仪检测各靶细胞凋亡比例(结果如图10所示),利用ELISA检测各孔上清IL-2及IFN-γ浓度(结果如图11和图12所示)。其中K562为BCMA阴性细胞,K562-BCMA,RPMI8226均为BCMA阳性细胞。结果显示PCDHF-73CART、PCDHF-74CART和PCDHF-42CART对BCMA阳性靶细胞有较强的特异性杀伤,并且3种CART细胞的杀伤阳性靶细胞能力基本一致,对BCMA阴性细胞几乎无杀伤作用;PCDHF-42CART,PCDHF-73CART和PCDHF-74CART杀伤BCMA阳性靶细胞时IL-2和IFN-γ分泌量处于同一水平,综合特异性杀伤和因子分泌的检测结果说明,人源化BCMA CART PCDHF-73CART和PCDHF-74CART与鼠源BCMA CART PCDHF-42CART对BCMA阳性靶细胞有同等的杀伤效果。
