Abstract

本发明涉及生物领域,特别是涉及一种抗CLD18A2单域抗体。本发明提供一种抗CLD18A2单域抗体,所述抗CLD18A2单域抗体的互补决定区CDR包括氨基酸序列如下所示的CDR1~CDR3:氨基酸序列如SEQ ID NO.4~11其中之一所示的CDR1,氨基酸序列如SEQ ID NO.19~26其中之一所示的CDR2,氨基酸序列如SEQ ID NO.33~39其中之一所示的CDR3。本发明所提供的抗CLD18A2单域抗体能够与CLD18A2上存在的表位特异性结合的单域抗体,其对应的融合蛋白对CLD18A2具有良好的特异性和亲和力,且具有明显的肿瘤抑制作用。

Description

一种抗CLD18A2单域抗体及其抗肿瘤用途
本申请是2019年1月15日提交的、申请号为2019100339954、名称为“抗CLD18A2纳米抗体及其应用”的中国发明专利申请的分案申请。
技术领域
本发明涉及生物领域,特别是涉及抗CLD18A2单域抗体及其应用。
背景技术
密蛋白18(Claudin 18,CLD18)是分子量约为28kD,位于上皮和内皮的紧密连接中的跨膜蛋白,紧密连接在相邻细胞之间。正常上皮组织中,由于细胞间隙紧密导致细胞表面的密蛋白难以被接触,而肿瘤细胞的间隙却较为疏松,因此肿瘤细胞上的密蛋白成为胞外抗体及免疫疗法的潜在靶点。CLD18具有四个疏水区,其作为跨膜区形成两个胞外域,其中疏水区1和疏水区2环绕形成胞外域1,疏水区3和疏水区4环绕形成胞外域2。由于基因不同剪切,CLD18形成两种剪切体:CLD18A1和CLD18A2。CLD18A1在正常肺部表达,而CLD18A2仅在胃细胞中表达;更重要的是,CLD18A2局限在已分化的胃上皮短寿细胞中,但在胃干细胞中不存在(Niimi T,et al.Biol.2001;21(21):7380–7390.)。这些特性显示CLD18A2是一个用于治疗胃癌和其他CLD18A2阳性肿瘤的有临床价值的治疗靶点。
发明内容
鉴于以上所述现有技术的缺点,本发明的目的在于提供一种抗CLD18A2单域抗体,用于解决现有技术中的问题。
为实现上述目的及其他相关目的,本发明提供一种抗CLD18A2单域抗体,所述抗CLD18A2单域抗体的互补决定区CDR包括氨基酸序列如下所示的CDR1~CDR3:氨基酸序列如SEQ ID NO.4~11其中之一所示的CDR1,氨基酸序列如SEQ ID NO.19~26其中之一所示的CDR2,氨基酸序列如SEQ ID NO.33~39其中之一所示的CDR3。
在本发明一些实施方式中,所述抗CLD18A2单域抗体的互补决定区CDR包括氨基酸序列如下所示的CDR1~CDR3:
(1)氨基酸序列如SEQ ID NO.4所示的CDR1,氨基酸序列如SEQ ID NO.19所示的CDR2,氨基酸序列如SEQ ID NO.33所示的CDR3;或者
(2)氨基酸序列如SEQ ID NO.5所示的CDR1,氨基酸序列如SEQ ID NO.20所示的CDR2,氨基酸序列如SEQ ID NO.34所示的CDR3;或者

具体实施方式
本发明人经过深入的研究,提供了一种与CLD18A2上存在的表位特异性结合的单域抗体,并进一步提供包括所述单域抗体的融合蛋白、免疫缀合物和表达靶向CLD18A2的嵌合抗原受体的细胞,所述蛋白或细胞对CLD18A2具有特异性和良好的亲和力,且具有明显的肿瘤抑制作用,在此基础上完成了本发明。
术语“抗体”或“免疫球蛋白”在本文中无论是指重链抗体还是指常规4链抗体,均用作一般术语以包括全长抗体、其单个的链以及其所有部分、结构域或片段(包括但不限于抗原结合结构域或片段,分别例如VHH结构域或VH/VL结构域)。此外,本文所用的术语“序列”(例如在“免疫球蛋白序列”、“抗体序列”、“单一可变结构域序列”、“VHH序列”或“蛋白序列”等的术语中)一般应理解为既包括相关氨基酸序列,又包括编码所述序列的核酸序列或核苷酸序列,除非本文需要更限定的解释。
术语“单克隆抗体”指单分子组成的抗体分子制备物。单克隆抗体显示对特定表位的单结合特异性和亲和性。
术语(多肽或蛋白的)“结构域”是指折叠蛋白结构,其能够独立于蛋白的其余部分维持其三级结构。一般而言,结构域负责蛋白的单个的功能性质,且在许多情况下可添加、移除或转移至其他蛋白而不损失蛋白的其余部分和/或结构域的功能。
术语“单域抗体(VHH)”、“纳米抗体(nanobody)”具有相同的含义,指克隆抗体重链的可变区,构建仅由一个重链可变区组成的单域抗体(VHH),它是具有完整功能的最小的抗原结合片段。通常从羊驼免疫血清中先获得天然缺失轻链和重链恒定区域1(CH1)的抗体后,再克隆抗体重链的可变区,构建仅由一个重链可变区组成的单域抗体(VHH)。
术语“单域抗体(VHH)”是指基本上由本领域及下文中分别称为“框架区1”或“FR1”、“框架区2”或“FR2”、“框架区3”或“FR3”、及“框架区4”或“FR4”的四个“框架区”组成的免疫球蛋白结构域,其中所述框架区由本领域及下文中分别称为“互补决定区1”或“CDR1”、“互补决定区2”或“CDR2”、及“互补决定区3”或“CDR3”的三个“互补决定区”或“CDR”间隔开。因此,单域抗体(VHH)的一般结构或序列可如下表示为:FR1-CDR1-FR2-CDR2-FR3-CDR3-FR4。单域抗体(VHH)因具有抗原结合位点而赋予抗体对抗原的特异性。
术语“重链单域抗体”、“VHH结构域”、“VHH”、“VHH抗体片段”、“VHH抗体”以及“单域抗体”(“Nanobody”为Ablynx N.V.公司,Ghent,Belgium的商标)可互换使用。
术语“IMGT编号系统”是一种专门针对人和其它脊椎动物的免疫球蛋白(IG)、T细胞受体(TCR)和主要组织相容性复合物(MHC)的集成信息系统,即THE INTERNATIONALIMMUNOGENETICS INFORMATION
Figure BDA0003241721790000061
(Lafranc等,2003,Dev.Comp.Immunol.27(1):55-77)。登录IMGT(http://www.imgt.org/IMGT_vquest),对抗体轻链和重链基因进行分析,以确定可变区的框架区(framework regions,FR)和互补决定区(complementaritydetermining regions,CDR)。CDR在免疫球蛋白可变结构域的结构内的“位置”在物种之间是保守的,并且存在于称为环的结构中,所以通过使用根据结构特征来使可变结构域序列对齐的编号系统,易于鉴定CDR和框架残基。这个信息可用于将来自一个物种的免疫球蛋白的CDR残基移植和替换至通常来自人抗体的接受体框架中。除非另有说明,否则在本说明书、权利要求书及附图中,抗CLD18A2单域抗体遵循IMGT编号方法进行编号,用以确定CDR区和FR区。
术语“特异性结合”意指此结合对于抗原是选择性的,并且能与不想要的或非特异性的相互作用区别开来。抗原结合模块结合特异性抗原决定簇的能力能经由酶联免疫吸附测定法(ELISA)或本领域技术人员熟知的其它技术,例如表面等离子共振技术(在BIAcore仪器上分析)(Liljeblad等,Glyco J17,323-329(2000)),以及免疫荧光技术。
术语“人源化抗体”指具有基本来自非人物种免疫球蛋白的抗原结合位点的分子,其中所述分子其余的免疫球蛋白结构是基于人免疫球蛋白的结构和/或序列。所述抗原结合位点可包含融合到恒定结构域上的完整可变结构域,或者仅包含移植到可变结构域中适当构架区的互补性决定区(CDR)。抗原结合位点可以是野生型的,或者通过一个或多个氨基酸替换进行修饰,例如进行修饰以与人免疫球蛋白更为相近。某些形式的人源化抗体保留了全部CDR序列(例如含有来自羊驼的全部三个CDR的人源化单域抗体)。其他形式具有一个或多个相对于原始抗体而言发生了改变的CDR。
术语“效应功能”在述及抗体时指那些可归于抗体Fc区且随抗体同种型而变化的生物学活性。抗体效应功能的例子包括:C1q结合和补体依赖性细胞毒性(CDC)、Fc受体结合、抗体依赖性细胞介导的细胞毒性(ADCC)、抗体依赖性细胞吞噬作用(ADCP)、细胞因子分泌、细胞表面受体(例如B细胞受体)下调和B细胞激活。
术语“抗体依赖性细胞介导的细胞毒性”或“ADCC”是指一种形式的细胞毒性,其中结合于某些细胞毒性细胞(例如天然杀伤(NK)细胞、嗜中性白细胞和巨噬细胞)上存在的Fc受体(FcR)上的分泌免疫球蛋白使得这些细胞毒性效应细胞能够特异性结合携带抗原的靶标细胞,并且随后用细胞毒素杀灭所述靶标细胞。抗体对细胞毒性细胞进行“武装”,并且绝对为所述杀灭所需。NK细胞作为用于介导ADCC的主要细胞仅表达FcγRIII,而单核细胞表达FcγRI、FcγRII和FcγRIII。已知FcR在造血细胞上表达(参见例如Ravetch和Kinet,1991,Annu.Rev.Immunol.9:457-92)。为评估目标分子的ADCC活性,可进行体外ADCC测定(参见例如美国专利号5,500,362和5,821,337)。适用于所述测定的效应细胞包括外周血液单核细胞(PBMC)和天然杀伤(NK)细胞。
术语“补体依赖性细胞毒性(Complement-dependent cytotoxicity)”或“CDC”是抗体指导的另一细胞杀伤方法。对于补体活化,IgM是最有效的同种型。IgG1和IgG3在通过经典补体活化途径指导CDC方面也都非常有效。优选地,在这一级联中,抗原-抗体复合物的形成导致紧邻参与抗体分子(例如IgG分子)CH2结构域的多个C1q结合位点暴露出来(C1q是补体C1的三种亚组分之一)。优选地,暴露的C1q结合位点将先前低亲和力的C1q-IgG相互作用转变成高亲合力相互作用,这触发了包括一系列其他补体蛋白的级联,并引起效应细胞趋化/活化剂C3a和C5a的蛋白水解释放。优选地,该补体级联最终形成膜攻击复合物,它在细胞膜中产生孔,有利于水和溶质自由穿行于细胞内外。
术语“CD3”是指人类CD3蛋白质的多重次单元复合体。CD3蛋白质多重次单元复合体由6个不同的多肽链组成。这些多肽链包括CD3γ链(SwissProt P09693)、CD3δ链(SwissProt P04234)、两个CD3ε链(SwissProt P07766)及一个与T细胞受体α及β链相关联的CD3ζ链同二聚体(homodimer)(SwissProt 20963)。术语“CD3”包括任何CD3变异体、异构体及物种同源物,其由细胞(包括T细胞)天然表达,或者可表达在经编码这些多肽的基因或cDNA转染的细胞上,除非另有注明。T细胞表面的分化簇3(CD3)是T细胞受体的共受体,协助细胞毒性T细胞的激活。
两个多肽序列之间的“序列相同性”指示序列之间相同氨基酸的百分比。“序列相似性”指示相同或代表保守氨基酸取代的氨基酸的百分比。用于评价氨基酸或核苷酸之间的序列相同性程度的方法是本领域技术人员已知的。例如,氨基酸序列相同性通常使用序列分析软件来测量。例如,可使用NCBI数据库的BLAST程序来确定相同性。
术语“嵌合抗原受体”、“CAR”是模拟TCR功能的人工受体,由抗原识别域、铰链区和跨膜区及胞内信号域依次连接组成,肿瘤细胞表面的抗原(受体)与嵌合抗原受体的抗体(配体)结合时,通过铰链区和跨膜区将信号传递至胞内,胞内信号域再将信号转化为活化信号,激活效应细胞,效应细胞通过分泌穿孔素或者产生细胞因子杀伤肿瘤细胞,同时效应细胞本身也发生扩增,进一步扩大免疫杀伤作用。
药剂的“有效量”指引起接受其施用的细胞或组织中的生理学变化所必需的量。
药剂例如药物组合物的“治疗有效量”指在必需的剂量和时间段上有效实现期望的治疗或预防结果的量。治疗有效量的药剂例如消除、降低、延迟、最小化或预防疾病的不良效果。
“个体”或“受试者”是哺乳动物。哺乳动物包括但不限于,驯养的动物(例如母牛、羊、猫、犬和马)、灵长类(例如人和非人灵长类如猴)、家兔和啮齿动物(例如小鼠和大鼠)。优选地,所述个体或受试者是人。
术语“药物组合物”指其形式使得其中含有的活性成分的生物学活性有效,且不含对会接受该组合物施用的受试者有不可接受的毒性的别的成分的制剂。
“药学可接受载体”指药物组合物中活性成分以外对受试者无毒的成分。药学可接受载体包括但不限于缓冲剂、赋形剂、稳定剂或防腐剂。
术语“治疗/预防”(及其语法变体)指试图改变治疗个体中疾病的自然进程,并且可以是为了预防或在临床病理学的过程期间实施的临床干预。治疗的期望效果包括但不限于预防疾病的发生或复发、缓解症状、降低疾病的任何直接或间接病理学后果、预防转移、减缓疾病进展的速率、改善或减轻疾病状态、及免除或改善预后。在一些实施方案中,本发明的抗体用于延迟疾病的形成或延缓病症的进展。
术语“抗原”是抗体可选择性结合的预定抗原。靶标抗原可为多肽、蛋白、核酸、细胞、脂质、半抗原或其它天然存在或合成化合物。在本文的一些实施方案中,靶标抗原是表达CLD18A2的细胞,更优选地,是表达CLD18A2分子中的其中一部分。
术语“全细胞差减筛选法”是近年在噬菌体展示技术上发展起来的一项高通量筛选技术,其利用成对的细胞对噬菌体文库进行差减筛选,可以在短时间内筛选出与靶细胞高亲和力结合的短肽。
“表位”是抗原分子的表面上的由单一抗体分子结合的位点,诸如抗原的表面上的能够结合于抗体的一个或多个抗原结合区,并且在动物诸如哺乳动物(例如人)中具有能够引发免疫应答的抗原性或免疫原性活性的局部化区域。具有免疫原性活性的表位是多肽在动物中引发抗体应答的部分。具有抗原性活性的表位是如通过本领域中熟知的任何方法(包括例如通过免疫测定)所测定的多肽的由抗体结合的部分。抗原性表位无需必定具有免疫原性。表位常常由分子诸如氨基酸或糖侧链的化学活性表面群聚组成并且具有特定三维结构特征以及特定电荷特征。表位可为线性表位或构象性表位。线性表位由蛋白质中的连续氨基酸序列形成。构象性表位由在蛋白质序列中不连续,但在蛋白质折叠成它的三维结构后集合在一起的氨基酸形成。当蛋白质的三维结构诸如在活化或结合另一蛋白质或配体之后呈改变的构象时,形成诱导的表位。在某些实施方案中,CLD18A2表位是CLD18A2蛋白的三维表面特征。在其它实施方案中,CLD18A2表位是CLD18A2蛋白的线性特征。通常,抗原具有若干或许多不同表位,并且可与许多不同抗体反应。

用途

本发明所提供的单域抗体、融合蛋白、免疫缀合物、药物组合物的“治疗有效量”优选地导致疾病症状的严重性降低,疾病无症状期的频率和持续时间增加,或者防止因疾病痛苦而引起的损伤或失能。例如,对于CLD18A2相关肿瘤的治疗(包括如胃癌),相对于未接受治疗的对象,“治疗有效量”优选地将细胞生长或肿瘤生长抑制至少约10%,优选至少约20%,更优选至少约30%,更优选至少约40%,更优选至少约50%,更优选至少约60%,更优选至少约70%,更优选至少约80%。抑制肿瘤生长的能力可以在预测对人类肿瘤的疗效的动物模型系统中评价。或者,也可以通过检查抑制细胞生长的能力来评价,这种抑制可以通过本领域技术人员公知的试验在体外测定。治疗有效量的单域抗体、融合蛋白、免疫缀合物、药物组合物通常能够减小肿瘤大小,或者以其他方式缓解对象的症状。本领域技术人员可以根据实际情况选择合适的治疗有效量,例如,可以是对象的大小、对象症状的严重性和选择的特定组合物或给药途径。治疗的处方(例如,对剂量的决定等)可以是由医生确定的,通常考虑的因素包括但不限于所治疗的疾病、患者个体的情况、递送部位、施用方法以及其它因素等。预防有效量指在必需的剂量和时间上有效实现期望的预防效果的量。通常而非必然,由于预防剂量是在疾病发作之前或在疾病的早期用于受试者的,因此“预防有效量”通常低于“治疗有效量”。本发明可诊断、治疗和/或预防的与表达CLD18A2的细胞相关的疾病的实例可以包括所有表达CLD18A2的癌症和肿瘤实体,具体可以是包括但不限于胃癌、食管癌、胰腺癌、肺癌、卵巢癌、乳腺癌、结肠直肠癌、肝癌、胆囊癌和头颈癌等,这些癌症可以为早期、中期或晚期,例如转移癌。

当实施例给出数值范围时,应理解,除非本发明另有说明,每个数值范围的两个端点以及两个端点之间任何一个数值均可选用。除非另外定义,本发明中使用的所有技术和科学术语与本技术领域技术人员通常理解的意义相同。除实施例中使用的具体方法、设备、材料外,根据本技术领域的技术人员对现有技术的掌握及本发明的记载,还可以使用与本发明实施例中所述的方法、设备、材料相似或等同的现有技术的任何方法、设备和材料来实现本发明。

11.1 aC18.2-CAR-T制备
由健康人外周血通过密度梯度离心法获得人外周血单个核细胞(上海妙通),并通过CD3MicroBeads(美天旎,MiltenyiBiotecGmbH)根据说明书进行分选。以约1×106/mL密度加入Quantum007淋巴细胞培养基液(购自PAA Laboratories GmbH公司)培养并以细胞:磁珠比例为1:1加入DynabeadsTMHuman T-Activator CD3/CD28(thermofisher)和终浓度100U/mL的重组人IL-2(上海近岸)刺激培养24h。然后以MOI≈5用上述重组慢病毒(实施例10.3)感染T细胞。感染后的细胞每隔一天采用5×105/mL的密度进行传代,同时在淋巴细胞培养液中补加终浓度100U/mL的重组人IL-2。在培养第8天时通过流式细胞检测,由于eGFP与CAR共表达,检测eGFP的阳性细胞认为表达嵌合抗原受体的阳性细胞。未感染的T细胞作为阴性对照,表达不同嵌合抗原受体的病毒感染T细胞其阳性率约为66.4%。
11.2 aC18.2-CAR-T的杀伤实验
我们观察了不同aC18.2-CAR-T细胞在体外对NUGC-4-CLD18A2细胞和CLD18A2阴性细胞系NUGC-4-CLD18A1的杀伤作用。效靶比分别设置为3:1、1:1和1:3,靶细胞数量为10000/孔。各组均设5个复孔,取5个复孔的平均值,共培养16h后,用LDH检测试剂盒(上海东仁)检测上清的LDH含量评价杀伤。结果表8显示在效靶比为3:1时,特异性aC18.2-CAR-T细胞能够有效杀伤CLD18A2表达阳性的细胞,而对CLD18A2阴性的细胞则几乎没有杀伤。以上结果显示,aC18.2-CAR-T能够特异性的杀伤CLD18A2阳性的细胞,且杀伤作用与效靶比呈正相关。

11.3体外细胞因子释放
将CLD18A2表达阳性的细胞NUGC-4-CLD18A2与aC18.2-CAR-T细胞以1:1的比例共同培养,孵育24h后收集培养上清,分别用IL-2(R&D Systems,Inc.)、TNF-α(R&D Systems,Inc.)和IFN-γ(R&D Systems,Inc.)按试剂盒说明书检测细胞因子。图11结果显示NUGC-4-CLD18A2中,aC18.2-CAR-T共孵育时IL-2、TNF-α和IFN-γ等细胞因子的分泌显著高于阴性细胞NUGC-4-CLD18A1。
11.4 aC18.2-CAR-T的体内药效学研究
以NUGC-4-CLD18A2,建立了皮下移植瘤模型。将3×106个NUGC-4-CLD18A2皮下接种NOD/SCID小鼠。至小鼠肿瘤平均体积达100-150mm3时,腹腔注射100mg/kg的环磷酰胺以清除NOD/SCID小鼠的免疫细胞,使得过继转移的转基因的T淋巴细胞更好的发挥抗肿瘤功能。第二日,通过尾静脉输注1.0×107个aC18.2-CAR-T细胞aC18.2-hu19V3-28-137Z,同时以表达28-137Z的Mock组作为对照,观察测量皮下移植瘤的生长。结果图12显示aC18.2-CAR-T细胞能够显著抑制NUGC-4-CLD18A2移植瘤的生长。
