本专利申请要求于2021年4月30日提交的申请号为CN202110481199.4的中国发明专利申请的优先权权益,在此将其全部内容引入作为参考。
技术领域
本发明涉及抗体药物偶联物,具体而言,本发明涉及靶向脊髓灰质炎病毒受体样分子4(Nectin-4)的抗体药物偶联物及其制备方法和用途。
背景技术
Nectins(脊髓灰质炎病毒受体样分子)是一类新颖的细胞粘附蛋白,与钙粘蛋白共同或单独调节细胞连接,家族成员包括Nectin-1、-2、-3、-4,它们都由具有3个Ig的环状结构、1个跨膜区、胞质尾区组成。在这些成员中,Nectin-4特异性表达于胚胎、胎盘以及肿瘤细胞中,已有研究发现其与多种肿瘤细胞的发生、发展有着密切联系。例如,对2394例肿瘤患者进行病理切片分析,发现Nectin-4广泛表达于膀胱癌、乳腺癌以及胰腺癌患者人群中。因此,Nectin-4已成为许多肿瘤或癌症的诊断和治疗的一个重要靶点。
抗体药物偶联物(Antibody-drug conjugate;ADC)是一种利用抗体对肿瘤细胞表面特定抗原的特异性识别能力,精准地将抗肿瘤药物(如细胞毒性剂、细胞抑制剂、小分子化疗物等)递送到肿瘤靶细胞,使之发生胞内积蓄并释放,进而精准杀伤肿瘤的技术。抗体药物偶联物一般由三部分组成:抗体或抗体类配体,小分子药物,将抗体或抗体类配体与药物偶联起来的连接子(接头)。由于分子量大小合适,稳定性高,靶向性强,毒副作用小,抗体药物偶联物已被认为是最具潜力的抗肿瘤药物。
但是,成功开发ADC也存在诸多必须考虑且解决的问题。例如,抗体需特异性地识别病变部位,免疫致敏性低,能够高效迅速地发生细胞内吞作用;抗体-药物接头,在血液中稳定性要高并需在所靶向的细胞中特异地被激活并高效释放小分子药物,否则会对正常细胞产生不可接受水平的毒性;所偶联的小分子药物需具有强细胞杀伤能力等。在目前进入临床试验的抗体药物偶联物中,高活性的细胞毒性小分子药物通常是通过连接子连接在抗体表面的赖氨酸残基或者铰链区域的半胱氨酸残基处,最佳药物/配体比值(DAR)为2-4。但是,抗体表面大量的赖氨酸残基(超过80个)以及偶联反应的非选择性,导致偶联数目和位点不确定,进而导致生成的抗体药物偶联物不均一。例如,由抗HER2靶向药物曲妥珠单抗与微管抑制剂美坦新(DM1)制成的抗体药物偶联物T-DM1(平均DAR为3.5),其DAR分布为0-8。同样,虽然抗体铰链区的链间二硫键只有四对,但为了达到最佳平均DAR(2-4)的要求,需要对链间二硫键进行部分还原。但是,现有还原剂(DTT、TCEP等)无法选择性地还原链间二硫键,因此生成的偶联物也不是均一的产物,而是由多种组分组成,主要组分的DAR为0、2、4、6、8,而且对应每一种特定DAR的组分都存在由于连接位点不同而形成的异构体。抗体药物偶联物产品的不均一性可导致各成员组分之间药物动力学性质、效价以及毒性的不均一性。例如,具有较高DAR的组分在体内被清除得更快,并导致更高的毒性。
目前,西雅图基因公司与安斯泰来合作,利用该公司特有的连接子mc-vc-MMAE与anti-Nectin-4抗体enfortumab进行随机偶联,得到一种anti-Nectin-4抗体药物偶联物Enfortumab Vedotin(Padcev)。临床试验结果显示,在接受化疗以及PD-1/PD-L1抑制剂治疗的患者中,接受Enfortumab Vedotin的患者的中位总生存期为12.9个月,比化疗对照组延长了3.9个月,显示了良好的肿瘤治疗效果。然而,临床研究同时发现,使用EnfortumabVedotin往往伴随发热、皮肤瘙痒、周围神经病、干眼症、中性粒细胞下降。这些不良反应与小分子与抗体连接过量、连接方式不稳定直接相关。
因此,本领域迫切需要提供高效、简单、实用的化学偶联方法用于靶向Nectin-4的抗体-药物偶联物研究与开发。
发明内容
本发明要解决的技术问题是,通过杂交瘤筛选和人源化技术,获得特异性结合人Nectin-4的高亲和力抗体,其中通过人源化设计,使该抗体最大程度减少鼠源氨基酸的数目,以拥有更好的体内安全性和应用前景;在此基础上,进一步筛选具有更强细胞内吞效应的抗体,将其与小分子化学药物制备成抗体药物偶联物(antibody-drug conjugate),利用该抗体对Nectin-4表达细胞的靶向性和经由靶点的强的内吞效应,结合该小分子化学药物的作用,以达到优异的肿瘤杀伤效果。

将分泌抗人Nectin-4抗体的杂交瘤细胞扩大培养后,提取细胞总RNA,反转录成cDNA;PCR扩增抗体轻链可变区IgVL(κ)和重链可变区VH序列,纯化扩增产物后连接至T载体并转化大肠杆菌细胞,菌株扩增、抽提质粒后进行DNA测序获得单克隆抗体的重轻链可变区序列。
将鼠源抗人Nectin-4单克隆抗体的重链可变区序列和公开发表的人单克隆抗体IgG1亚类的重链恒定区序列(SEQ ID NO:9)拼接在一起,构建到哺乳动物细胞表达载体中;将鼠源抗人Nectin-4单克隆抗体的轻链可变区序列和公开发表的人单克隆抗体κ亚类的轻链恒定区序列(SEQ ID NO:10)拼接在一起,构建到哺乳动物细胞表达载体中。构建好的抗人Nectin-4嵌合抗体的重链载体和轻链载体配对混合,使用PEI转染HEK293细胞,约7天后收集细胞上清,使用Mabselect纯化得到抗人Nectin-4嵌合抗体。
综合抗体编码方案,确定鼠源抗体的重轻链6个抗原互补决定簇(CDR)的氨基酸序列区域与支撑抗体保守三维构象的框架区。随后通过分析搜索已知人源抗体序列,选择与鼠源抗体最为相似接近的人源抗体重链可变区序列,如IGHV1|IGHJ4*01,选择其抗体框架区序列作为模板,将鼠源抗体重链CDR与人源抗体框架区结合,最终生成人源化抗体重链可变区序列。同样过程,生成人源化抗体轻链可变区序列。根据结合活性变化,根据需要将框架区个别氨基酸进行从人源改回鼠源的回复突变,和/或对存在的翻译后修饰位点等个别氨基酸进行修改,最终获得备选的人源化的重链可变区和轻链可变区。
将人源化的重链可变区和轻链可变区两两组合,参考嵌合抗体的制备,获得人源化抗体。通过针对人Nectin-4的体外细胞结合实验、靶标癌细胞内吞实验、靶标癌细胞增殖抑制实验、与已知含药接头制成ADC筛选抗原结合、内吞活性或药效等,筛选出如下人源化抗体,下划线显示CDR:

实施例组2抗体偶联药物的制备与理化表征
示例性地,使用以下方法进行实验。
2.1含药接头C-1、C-2、C-3、C-4的制备
化合物按照WO2018/095422A1公开的方法合成,产物均为黄色固体,LC-MS(ESI):M+1分别为1927(C-1)、1987(C-2)、1963(C-3)和1995(C-4)。
含药接头MC-VC-MMAE购自MCE。
2.2定点偶联的抗体药物偶联物的制备
根据专利申请CN202011046911X所述的抗体药物偶联物制备方法:将抗体经还原打开二硫键,再与含药接头进行偶联形成抗体药物偶联物,再经水解打开马来酰亚胺环,最后经纯化得到DAR=4的抗体药物偶联物(发明专利申请CN202011046911X的全部内容以引用方式并入本文)。
具体示例性方法如下:
样品还原与偶联:将抗体样品使用Sephadex G-25载体的NAP-25脱盐柱置换至pH值7.4含有50mM的氯化钠、50mM磷酸二氢钠-磷酸氢二钠缓冲溶液中,并将抗体浓度稀释至10mg/ml。取10ml共计100mg的抗体样品,以抗体-还原剂摩尔比1比10当量添加10mg/ml的TCEP(Sigma-Aldrich)的水溶液。孵育2小时后,使用Sephadex G25脱盐柱将反应溶液进行置换,置换至pH 7.0含有50mM氯化钠,50mM磷酸二氢钠-磷酸氢二钠的缓冲溶液中。
将上述还原后的抗体稀释至5mg/mL,依次加入反应总体积7.4%的1.33ml N,N-二甲基乙酰胺(DMA)作为预溶剂、以抗体-小分子药物摩尔比1比5.5倍当量添加含10mg/mL药物接头的DMA-药物接头混合溶液。室温搅拌60分钟。Sephadex G-25载体的NAP-25脱盐柱将反应液置换至pH8.0的磷酸氢二钠-磷酸二氢钠缓冲溶液,除去过量的药物接头,37℃水浴加热3小时。在水浴加热前后,分别进行质谱分析偶联产物结构。不同偶联产物的分析结果均表明,在水浴之前偶联产物为式Ia结构,水浴之后,得到完全开环的式Ib结构,即100%水解。
样品纯化:将上述样品使用AMICOM超滤离心管进行浓缩,将样品浓缩至15mg/mL左右。添加50mM磷酸氢二钠-磷酸二氢钠+3M磷酸铵缓冲溶液至电导率为74ms/cm。上样至Butyl-Sepharose 4FF填料(购自GE Healthcare)疏水柱,使用A相为50mM磷酸氢二钠-磷酸二氢钠+0.45M硫酸铵;B相为50mM磷酸氢二钠-磷酸二氢钠的缓冲溶液。B相0-80%线性梯度12倍柱体积、B相100%等度梯度洗脱,对主峰进行收集。
使用AMICOM超滤离心管将最终样品置换至pH值7.4的50mM的磷酸氢二钠-磷酸二氢钠缓冲液中,并使用0.22um的滤膜进行过滤(Sartorius stedim Ministart)。
如实际反应规模≥1g,在反应当量比不变的情况下,将上述Sephadex G-25载体脱盐步骤以及AMICOM超滤离心管替换为HYDRO-30kD(Sartorius)超滤膜包。其他主要参数不变。
2.3定点偶联的抗体药物偶联物的理化表征
a.紫外分光光度法测定药物抗体偶联比(UV-DAR法)与浓度
抗体药物偶联物浓度可通过测定在280nm及小分子特征吸收波长下的UV吸光度,然后进行下述计算而得到。
a1.随机偶联药物的药物抗体偶联比(DAR)测定
根据文献[Clin Cancer Res.2004Oct 15;10(20):7063-70]可知 其中,为抗体在280nm下摩尔吸收系数,A280为抗体药物偶联物在280nm下紫外吸收值,A248为抗体药物偶联物在含药接头特征吸收波长248nm下紫外吸收值,为抗体在含药接头特征吸收波长248nm下摩尔吸收系数,为含药接头在其特征吸收波长248nm下摩尔吸收系数,为含药接头在280nm下摩尔吸收系数。
其中:
a2.定点偶联药物的药物抗体偶联比(DAR)测定
根据文献[Clin Cancer Res.2004Oct 15;10(20):7063-70]可知 其中,为抗体在280nm下摩尔吸收系数,A280为抗体药物偶联物在280nm下紫外吸收值,A251为抗体药物偶联物在含药接头特征吸收波长251nm下紫外吸收值,为抗体在含药接头特征吸收波长251nm下摩尔吸收系数,为含药接头在其特征吸收波长251nm下摩尔吸收系数,为含药接头在280nm下摩尔吸收系数。
其中:
注:BL20E为上文中C-3化合物去掉离去基团R并且马来酰亚胺环开环后的产物。
a3.药物浓度测定
由于某一波长下的总吸光度等于存在于体系内的所有吸收化学物质种类的吸光度的和(吸光度的加成性),所以假设在抗体与含药接头偶联前后,抗体及含药接头的摩尔吸光系数不发生变化时,抗体药物偶联物浓度有如下关系:
其中,MWADC为抗体药物偶联物分子量,MWab为抗体分子量,MWD为含药接头分子量。

实施例组3抗体药物偶联物的体外杀伤作用与体内药效研究
示例性地,使用以下方法进行实验。
3.1体外杀伤作用研究方法
本实验利用人乳腺导管癌细胞BT474细胞(购自ATCC)。用完全培养基(RPMI 1640培养基45ml,5ml FBS,混匀后使用)将BT474细胞密度调到15×104之后,100μl/孔加入细胞培养板中,过夜培养。第二天,用上述完全培养基稀释ADC样品,分别稀释到50ug/ml,之后再4倍梯度稀释,共9个梯度加零点,所有样品均设3个复孔。设阴性对照(细胞+培养基)和空白对照(无细胞,纯培养基);将上述稀释后的ADC样品依次加入到过夜培养的细胞培养板中,100μl/孔。然后置于细胞培养箱中孵育96h。取出细胞培养板,40μl/孔加入MTS后,37℃培养箱反应2-4h;取出细胞板,在490nm处读取OD值。
3.2体内药效研究方法
分别使用人乳腺导管癌细胞BT474细胞(购自ATCC)、人乳腺癌细胞MDA-MB-468(购自ATCC)对裸小鼠(BALB/cJGpt-Foxn1nu/Gpt,4-5周)进行接种造模。待肿瘤生长至100-200mm3后,对小鼠静脉注射(IV)给药,给药体积10mL/kg;溶剂组给予相同体积的溶剂(生理盐水);具体给药剂量和给药方案见下文。每周测2次肿瘤体积,称小鼠体重,记录数据。
实验结束、达到实验终点或肿瘤体积达到1500mm3,CO2麻醉处死动物,随后解剖取瘤并拍照。
3.3体内药效统计方法
实验指标为考察药物对肿瘤生长的影响,具体指标为T/C%或抑瘤率TGI(%)。
每周二次用游标卡尺测量肿瘤直径,肿瘤体积(V)计算公式为:
V=1/2×a×b2,其中a、b分别表示长、宽。
T/C(%)=(T-T0)/(C-C0)×100,其中T、C为实验结束时的肿瘤体积;T0、C0为实验开始时的肿瘤体积。
抑瘤率(TGI)(%)=100-T/C(%)。
当肿瘤出现消退时,抑瘤率(TGI)(%)=100-(T-T0)/T0×100
如果肿瘤比起始体积缩小,即T<T0或C<C0时,即定义为肿瘤部分消退(PR);如果肿瘤完全消失,即定义为肿瘤完全消退(CR)。

实施例2靶向Nectin-4抗体药物偶联物的Fc功能区分析
使用BIAcore测定hH2L1、3d和Padcev与Fc受体的亲和力,Fc受体包括:FcRn、人FcγR I(CD64)、人FcγR IIa(人CD32a(H167))、人FcγR IIb(人CD32b)和人FcγRIIIa(人CD16a(V176))。将人FcγR I(CD64)、FcγR IIa(CD32a(H167))、FcγR IIb(CD32b)和FcγRIIIa(CD16a(V176))蛋白用运行试剂1(10mM N-(2-羟乙基)哌嗪-N-2磺酸,150mM氯化钠,3mM乙二胺四乙酸,0.005%吐温-20,pH调至7.4)稀释至0.25μg/mL,FcRn蛋白用运行试剂2(2mM磷酸二氢钠,10mM磷酸氢二钠,137mM氯化钠,2.7mM氯化钾,0.05%吐温-20,pH调至6.0)稀释至0.25μg/mL并以10μL/min的流速依次注入到His捕获芯片实验通道(FC2)约40RU。参比通道(FC1)不需要进行配体的捕获。将待测样品用相应运行试剂稀释,稀释后的样品依次以30μL/min的流速注入到实验通道和参比通道,结合和解离相应时间。使用Biocore 8K分析软件计算每个抗体的KD值。参比通道(FC1)用于背景的扣减。
hH2L1、3d和Padcev与Fc受体亲和力检测结果见表14。结果显示,hH2L1及4批3d与Fc受体的亲和力批间无显著差异;3d及1批Padcev与FcγR IIIa的亲和力整体略差于hH2L1,其余受体的亲和力三者之间无明显差异。

实施例3靶向Nectin-4抗体偶联药物内吞活性研究
以高表达Nectin4的稳转细胞株PC-3-Nectin4(2-4)(自制)细胞作为靶细胞检测HH2L1、3D及PADCEV的药物内吞作用。
实验方法:取生长至对数期的靶细胞,离心收集细胞,以完全培养基(含有10%FBS和250μg/ml G418的F-12K培养基)调整密度至5×105个/ml,分别吸取1ml细胞悬液至EP管中,即5×105个细胞,然后离心,弃上清,并用PBS清洗两遍。取样品hH2L1、3d及PADCEV各200μl加入细胞中,然后分别置于4℃(作为对照组)和37℃(作为实验组),反应2h后加入荧光标记二抗Goat Anti human IgG Fc-FITC(购自Sigma)4℃孵育1h,最后利用流式细胞仪检测荧光强度,按公式计算样品内吞率:tx时间点的内吞百分比=(1-37℃样品的荧光值/4℃样品的荧光值)×100%(tx表示一抗与细胞孵育的x时间)
结果表明,通过与无关抗体比较,PC-3-Nectin4(2-4)细胞表面有较高水平的靶蛋白Nectin4的表达,且与目的ADC、裸抗及PADCEV均有较强的结合能力。从目前的结果来看,3d及三批ADC原液与PADCEV的药物内吞效应之间无明显差异。
实验结果见表15。
