Description
本申请是申请日为2011年3月11日、中国专利申请号为201180013661.2(国际申请号为PCT/US2011/028172)、发明名称为“CD37结合分子及其免疫缀合物”的发明专利申请的分案申请。
技术领域
本发明总体上涉及结合CD37的抗体、及其抗原结合片段、多肽以及免疫缀合物,而且涉及使用这些CD37结合分子来治疗诸如B细胞恶性肿瘤的方法。
背景技术
白细胞抗原CD37(“CD37”),也称为GP52-40、四跨膜蛋白-26或TSPAN26,是四跨膜蛋白超家族的跨膜蛋白(Maecker等人,1997FASEB J.11:428-442)。它是具有四个跨膜结构域的重糖基化蛋白,在前B细胞至外周成熟B细胞阶段过程中在B细胞上表达,但在至浆细胞的终末分化中缺乏。(Link等人,1987,J Pathol.152:12-21)。CD37抗原仅微弱表达于T细胞、髓样细胞以及粒细胞(Schwartz-Albiez等人,1988,J.Immunol.,140(3)905-914)。然而,CD37还表达于恶性B细胞,例如那些建立的非何杰金氏淋巴瘤(NHL)和慢性淋巴系白血病(CLL)(Moore等人,1986,J Immunol.137(9):3013-8)。该表达情况表明,CD37表现为B细胞恶性肿瘤的有前景的治疗靶。
尽管CD37的确切生理学作用不清楚,但研究表明其在T细胞增殖中的潜在作用(van Spriel等人,2004,J Immunol.,172(5):2953-61)。CD37作为细胞表面糖蛋白的四跨膜家族的部分,还可与其他表面蛋白络合(Angelisová1994,Immunogenetics.,39(4):249-56)。CD37表达缺陷的小鼠被开发,显示在淋巴样器官的发育和细胞组成上没有变化。仅观察到IgG1水平下降和对于T细胞依赖性抗原的应答改变(Knobeloch等人,2000,Mol CellBiol.,20(15):5363-9)。
抗体显现为治疗所述癌症的有前景的方法。特别地,能够诱导靶细胞凋亡的抗体是合乎需要的。另外,具有补体依赖性细胞毒性活性(CDC)和抗体依赖性细胞毒性(ADCC)的抗体也是合乎需要的。
目前,被称为利妥昔单抗(rituximab)的抗CD20抗体用于治疗B细胞恶性肿瘤(Leget等人,1998,Curr.Opin.Oncol.,10:548-551)。然而,仅亚组患者响应利妥昔单抗治疗,甚至服用妥昔单抗的响应患者最终复发,且常发生对利妥昔单抗治疗的抗药性。另外,还将CD37结合剂作为B细胞恶性肿瘤的潜在治疗剂进行试验。楚邦制药公司(TrubionPharmaceuticals)开发了CD37结合剂SMIP-016和TRU-016(Zhao等人,2007,Blood,110:2569-2577)。SMIP-016是一种单链多肽,包括来自杂交瘤的可变区和工程化人恒定区。TRU-016是抗CD37 SMIP抗原的人源化形式。见,例如,美国公开的第2007/0009519号申请。对于TRU-016进行临床试验,用于治疗慢性淋巴细胞白血病(CLL)。勃林格殷格翰(BoehringerIngelheim)也已经揭示了国际公布的第WO 2009/019312号申请中的CD37结合剂。然而,尚无对于这些结合剂中的任何结合剂的CDC活性进行描述,且没有描述中缺乏交联剂(cross-linking agent)的情况下的体外促细胞凋亡活性。
已经使用放射标记的抗CD37抗体MB-1在两个分开的试验中对于放射免疫治疗(RIT)进行尝试。将131I-MB-1的治疗剂量施用于6个复发的NHL患者(Press等人,1989J ClinOncol.7(8):1027-38,Press at el.1993,N Engl J Med.329(17):1219-24)。所有6个患者在持续4至31个月的时间获得完全缓解(CR)。在另一个试验中,将131I-MB-1施用于10个复发的NHL患者(Kaminski等人,1992J Clin Oncol.10(11):1696-711)。总共4个患者在持续2至6个月的时间范围具有响应,但仅报道个过CR。然而,由于放射标记物不利的生物分布所提出的对于重要的非靶器官的放射暴露的考虑,并非所有患者都能够得以治疗。确实,在这些试验中观察到RIT相关的毒性,包括严重的骨髓抑制和心肺毒性。尽管这些临床数据表明抗CD37放射免疫缀合物有效,但这些治疗剂施用麻烦,并且由于与高剂量放射相关的危险,复发的RIT后患者不能使用RIT来再治疗。
为了克服RIT的局限性,已经开发了抗体-细胞毒性剂缀合物(ACC),也称为抗体-药物缀合物(ADC)。这些是免疫缀合物,包括通过化学接头与抗体共价连接的细胞毒性剂,所述化学接头可允许细胞毒性药物特异性递送至表达被抗体识别的蛋白的细胞。然而,不良内化的蛋白被认为不是这些治疗剂的有利的靶。CD37在结构上与CD20相似,因为这两种抗原都含有四个跨膜结构域,但CD20不是四跨膜蛋白家族的部分(Tedder等人,1989,J.Immun.142:2560-2568)。已经对针对几种B细胞抗原(包括CD37和CD20)的抗体研究了它们进行细胞内吞和降解的能力(Press等人,1989,Cancer Res.49(17):4906-12,和Press等人,1994,Blood.83(5):1390-7)。在体外,抗CD37抗体MB-1滞留于细胞表面并在Daudi淋巴瘤细胞中被缓慢内化。MB-1抗体还在体外在NHL患者细胞中具有低的细胞内吞和细胞内代谢速率。对于抗CD20抗体1F5获得了相似的结果,抗CD20抗体1F5也主要滞留于淋巴瘤细胞表面且内化不良。先前还对于CD20抗体的ADC进行了研究,但没有显示显著强效,特别是当使用非二硫化物或酸稳定接头时(见,例如Polson等人,2009,Cancer Res.,69(6):2358-2364)。鉴于这些观察结果,认为CD37并非抗体-药物缀合物的有利的靶。
因此,存在对于作为治疗B细胞恶性肿瘤的工具的CD37结合剂的需要,所述CD37结合剂包括抗体、其抗原结合片段以及抗体-药物缀合物(免疫缀合物)。本发明提供了该需要。

I.定义
为了促进对于本发明的理解,下文定义了一些术语和用语。
除非另有指明,本文使用的术语CD37是指任何天然CD37。CD37也被称为GP52-40、白细胞抗原CD37以及四跨膜蛋白-26。术语“CD37”包括“全长”、未加工的CD37以及产生于细胞中的加工的任何形式的CD37.该术语还包括CD37的天然存在的变体,例如剪接变体,等位基因变体,以及亚型。本发明描述的CD37多肽可分离自多种来源,例如来自人组织型或来自其他来源,或者通过重组或合成方法制备。
术语“抗体”表示通过免疫球蛋白的可变区内的至少一个抗原识别位点识别并特异性结合靶的免疫球蛋白分子,所述靶例如蛋白、多肽、肽、碳水化合物、多核苷酸、脂质或前述的组合。本文使用的术语“抗体”包括完整的多克隆抗体、完整的单克隆抗体、抗体片段(例如,Fab、Fab'、F(ab')2以及Fv片段)、单链Fv(scFv)突变体、多特异性抗体(例如产生自至少两个完整抗体的双特异性抗体)、嵌合抗体、人源化抗体、人抗体、包含抗体的抗原确定部分的融合蛋白、以及包含抗原识别位点的任何其他修饰的免疫球蛋白分子,只要该抗体表现所需的生物活性。抗体可为五种主要免疫球蛋白的任何种类:基于其重链恒定区的鉴定(被称为α、δ、ε、γ以及μ),分别为IgA、IgD、IgE、IgG以及IgM,或者其亚类(同种型)(例如,IgG1、IgG2、IgG3、IgG4、IgA1以及IgA2)。不同种类的免疫球蛋白具有不同的和公知的亚单位结构和三维构象。抗体可为裸露的或与其他分子缀合,例如毒素、放射性同位素等。
“阻断”抗体或“拮抗剂”抗体是一种抑制或降低其结合抗原(例如CD37的生物活性的抗体。在一些实施方案中,阻断抗体或拮抗剂抗体基本上或完全抑制抗原的生物活性。生物活性可被降低10%、20%、30%、50%、70%、80%、90%、95%或甚至100%。
术语“抗CD37抗体|”或“结合CD37的抗体”是指能够以足够亲和力结合CD37的抗体,使得抗体可用作靶向CD37的诊断剂和/或治疗剂。抗CD37抗体与无关的、非CD37蛋白结合的程度可小于抗体与CD37结合的约10%,这通过例如放射免疫测定(RIA)来检测。在某些实施方案中,结合CD37的抗体具有≤1μM、≤100nM、≤10nM、≤1nM或≤0.1nM的解离常数(Kd)。
术语“抗体片段”是指完整抗体的一部分,是指完整抗体的抗原决定可变区。抗体片段的实例包括但不限于Fab、Fab'、F(ab')2以及Fv片段,直链抗体、单链抗体以及形成于抗体片段的多特异性抗体。
“单克隆抗体”是指涉及对于单抗原决定簇或表位的高特异性识别和结合的同质性抗体群。这与通常包括针对不同抗原决定簇的不同抗体的多克隆抗体形成对照。术语“单克隆抗体”包括完整的和全长的单克隆抗体以及抗体片段(例如,Fab、Fab'、F(ab')2、Fv),单链(scFv)突变体、包含抗体部分的融合蛋白,以及包含抗原识别位点的任何其他修饰的免疫球蛋白分子。另外“单克隆抗体”是指以任何形式制备的这些抗体,包括但不限于通过杂交瘤、噬菌体选择、重组表达以及转基因动物。
术语“人源化抗体”是指作为含有最少非人(例如,鼠)序列的特异性免疫球蛋白链、嵌合免疫球蛋白或其片段的非人(例如,鼠)抗体形式。通常,人源化抗体为其中来自互补决定区(CDR)的残基被来自具有所需特异性、亲和力和能力的非人物种(例如,小鼠、大鼠、家兔、仓鼠)的CDR的残基取代的人免疫球蛋白(Jones等人,1986,Nature,321:522-525;Riechmann等人,1988,Nature,332:323-327;Verhoeyen等人,1988,Science,239:1534-1536)。在一些情况中,人免疫球蛋白的Fv框架区(FR)被来自非人物种的具有所需特异性、亲和力以及能力的抗体中的相应残基取代。人源化抗体可进一步通过Fv框架区和/或取代的非人残基中的另外的残基取代来修饰,以对于抗体特异性、亲和力和/或能力进行精和优化。通常,人源化抗体包括基本上所有可变结构域,其中至少一种、通常两种或三种可变结构域含有与非人免疫球蛋白相对应的所有或基本上所有CDR区,而所有或基本上所有FR区为人免疫球蛋白共有序列的那些。人源化抗体还可包括免疫球蛋白恒定区或结构域(Fc)的至少一部分(通常是人免疫球蛋白)。用于生成人源化抗体的方法的实例中美国专利5,225,539中描述。
抗体的“可变区”是指单独的或组合的抗体轻链的可变区或抗体重链的可变区。重链和轻链可变区各自由通过三个互补决定区(CDR,也称为高可变区)连接的四个框架区(FR)组成。各链中的CDR通过FR紧密结合,并且与来自其他链的CDR一起促进抗体的抗原结合位点形成。具有至少两种确定CDR的技术:(1)一种基于交叉物种序列变异性的方法(即,Kabat等人,Sequences of Proteins of Immunological Interest,(第5版,1991,National Institutes of Health,Bethesda Md.));和(2)一种基于抗原-抗体复合物的结晶学研究的方法(Al-lazikani等人(1997)J.Molec.Biol.273:927-948))。另外,本领域中有时将这两种方法的组合用于确定CDR。
当提及可变结构域中的残基时,通常使用Kabat编号系统(大约是轻链的残基1-107和重链的残基1-113)(例如,Kabat等人,Sequences of Immunological Interest.第5版,Public Health Service,National Institutes of Health,Bethesda,Md.(1991))。
Kabat中的氨基酸位置编号是指用于抗体的编辑的重链可变结构域或轻链可变结构域的编号系统(Kabat等人,Sequences of Proteins of Immunological Interest,第5版,Public Health Service,National Institutes of Health,Bethesda,Md.(1991))。使用该编号系统,实际的直链氨基酸序列可含有与可变结构域的FR或CDR的缩短或插入相对应的较少的或另外的氨基酸。例如,重链可变结构域可包括在H2的残基52之后的单个氨基酸插入(根据Kabat的残基52a)和在重链FR残基82之后插入的残基(例如,根据Kabat的残基82a、82b以及82c)。可通过对于抗体序列的同源区与“标准的”Kabat编号序列进行比对来对给定的抗体确定残基的Kabat编号。Chothia则提及了结构环的位置(Chothia和LeskJ.Mol.Biol.196:901-917(1987))。当使用Kabat编号规定来编号时,Chothia CDR-H1环的末端根据环的长度在H32和H34之间不同(这是因为Kabat编号方案中H35A和H35B安置了插入;如果35A或35B均不存在,环状32处结束;如果仅存在35A,环在33处结束;如果35A和35B均存在,环在34处结束)。AbM高可变区表现了在Kabat CDR和Chothia结构环之间的一致,被Oxford Molecular的AbM抗体造模软件使用。
术语“人抗体”是指人产生的抗体,或者使用本领域已知的任何技术制备的具有与人产生的抗体对应的氨基酸序列的抗体。人抗体的该定义包括完整或全长抗体、其片段,和/或包含至少一个人重链和/或轻链多肽的抗体,例如包含鼠轻链和人重链多肽的抗体。
术语“嵌合抗体”是指其中免疫球蛋白分子的氨基酸序列衍生自两个或多个物种的抗体。通常,轻链和重链的可变区与衍射自一个哺乳动物物种(例如,小鼠、大鼠、家兔等)的具有所需特异性、亲和力以及能力的抗体可变区对应,而恒定区与衍生自另一个物种(通常是人)的抗体中的序列具有同源性,以避免引发该物种中的免疫反应。
术语“表位”或“抗原决定簇”在本发明中可互换使用,是指能够被特定抗体识别和特异性结合的抗原的部分。当抗原是多肽时,可由连续氨基酸和通过蛋白质的三级折叠而并置的非连续氨基酸形成表位。由连续氨基酸形成的表位通常在蛋白质变性时保留,而由三级折叠形成的表位通常在蛋白质变性时丧失。在独特的空间构象中,表位通常包括至少3给且通常更多,至少5给或8-10给氨基酸。
“结合亲和力”通常是指一个分子(例如,抗体)的单结合位点及其结合配偶体(例如,抗原)之间的非共价相互作用的总数的强度。除非另有指明,本文使用的“结合亲和力”是指反映了结合对(例如抗体和抗原)的成员之间的1:1相互作用的固有结合亲和力。分子X与其配偶体Y的亲和力通常通过解离常数(Kd)来表示。可通过本领域公知方法来测量亲和力,包括本发明描述的那些方法。低亲和力抗体通常缓慢结合抗原且倾向于容易解离,而高亲和力抗体通常较快结合抗原且倾向于仍较长时间结合。本领域已知多种测量结合亲和力的方法,其中任何方法可用于本发明的目的。下文描述了具体的说明性实施方案。
本发明提及结合亲和力时使用的“或更好”是指分子及其结合配偶体之间的较强的结合。本文使用的“或更好”是指较强的结合,通过较小的Kd数字数值来表示。例如,对于抗原具有“0.6nM或更好”的亲和力的抗体,该抗体对于抗原的亲和力为<0.6nM,即,0.59nM、0.58nM、0.57nM等,或小于0.6nM的任何数值。
对于“特异性结合”,通常是指抗体通过其抗原结合结构域与表位结合且该结合赋予抗原结构域和表位之间一些互补性。根据该定义,当抗体与表位结合时,抗体被说成“特异性结合”该表位,通过其抗原结合结构域结合表位比其结合随机、无关的表位更容易。本文使用的术语“特异性”对某些抗体结合某些表位的相对亲和力进行定性。例如,抗体“A”可被认为比抗体“B”对于给定的表位具有较高的亲和力。或者抗体“A”被说成是以比其对相关表位“D”更高的亲和力结合表位“C”。
对于“优先结合”,是指抗体比其结合相关的、相似的、同源性或类似表位更容易地特异性结合表位。因此,“优先结合”给定表位的抗体比相关的表位更可能结合该表位,即使这样的抗体可与相关表位交叉反应。
如果抗体与给定表位的结合达到了在某种程度上其阻断参考抗体与该表位的结合的程度,则该抗体被说成“竞争性抑制”参考抗体与该表位的结合。竞争性抑制可通过本领域已知的任何方法来确定,例如,竞争性ELISA测定。抗体可被说成竞争性抑制参考抗体与给定表位的结合达至少90%、至少80%、至少70%、至少60%或至少50%。
本文使用的用语“基本上相似”或“基本上相同”是指两个数值之间(通常一个数值与本发明的抗体相关,另一个数值与参考/对照抗体相关)足够高度的相似性,使得本领域技术人员认为在所述数值(例如,Kd值)测量的生物特性情况下两个数值之间的差异很小或者无生物学和/或统计学意义。所述两个数值之间的差异作为参考/对照抗体的数值的函数可小于约50%、小于约40%、小于约30%、小于约20%或小于约10%。
被“分离的”多肽、抗体、多核苷酸、载体、细胞或组合物为作为天然情况未发现的形式的多肽、抗体、多核苷酸、载体、细胞或组合物。分离的多肽、抗体、多核苷酸、载体、细胞或组合物包括已经被纯化至不再是天然情况下发现的形式的程度的那些。在一些实施方案中,分离的多肽、抗体、多核苷酸、载体、细胞或组合物是基本上纯的。
本文使用的“基本上纯的”是指至少50%纯(即,无污染物)、至少90%纯、至少95%纯、至少98%纯或至少99%纯。
本文使用的术语“免疫缀合物”或“缀合物”是指与细胞结合剂(即,抗CD37抗体或其片段)连接并由通式C-L-A(其中,C=细胞毒素,L=接头,A=细胞结合剂或抗CD37抗体或抗体片段)定义的化合物或其衍生物。免疫缀合物还可由反序的通式定义:A-L-C。
接头是能够将化合物、通常药物(例如美登素)与细胞结合剂(例如抗CD37抗体或其片段)以稳定、共价方式连接的任何化学部分(moiety)。在化合物或抗体仍具有活性的条件下,接头可易感于或基本上抵抗酸诱导的裂解、光诱导的裂解、肽酶诱导的裂解、酯酶诱导的裂解以及二硫键裂解。合适的接头为本领域公知,包括,例如二硫基、硫醚基、酸敏感性基团、光敏感性基、肽酶敏感性基团以及酯酶敏感性基团。接头还可包括本发明描述和本领域已知的带电荷的接头及其亲水形式。
术语“癌”和“癌的”是指或描述其中细胞群具有未调节的细胞生长的特性的哺乳动物中的生理状况。癌的实例包括但不限于癌瘤、淋巴瘤、胚细胞瘤、肉瘤以及白血病。“肿瘤”和“新生物”是指产生于过度细胞生长或增殖的一种或多种细胞,例如良性(非癌的)或恶性(癌的),包括癌前病变。可治疗和/或预防的“癌”或“致瘤”疾病的实例包括B细胞淋巴瘤,包括NHL、前B细胞成淋巴细胞白血病/淋巴瘤以及成熟B细胞新生物,例如B细胞慢性淋巴细胞性白血病(CLL)/小淋巴细胞性白血病(SLL),B细胞前淋巴细胞性白血病,淋巴浆细胞淋巴瘤、外套细胞淋巴瘤(MCL)、滤泡性淋巴瘤(FL),包括低度、中度以及高度FL,皮肤滤泡中心淋巴瘤,缘区B细胞淋巴瘤(MALT型,结节型以及脾型),毛细胞性白血病、弥漫性大B细胞淋巴瘤,伯基特氏淋巴瘤、浆细胞瘤、浆细胞性骨髓瘤、移植后淋巴增生性障碍、沃尔登斯特伦氏氏巨球蛋白血症,以及间变大细胞淋巴瘤(ALCL)。
术语“癌细胞”、“肿瘤细胞”以及语法等同术语是指衍生自肿瘤或癌前病变的细胞总群,包括非致瘤性细胞(包括肿瘤细胞群块)和致瘤性干细胞(癌干细胞)。本文使用的术语“肿瘤细胞”当单独指缺乏更新和分化能力的那些肿瘤细胞时将被术语“非致瘤性”修饰,以区别那些肿瘤细胞和癌干细胞。
术语“受治疗者”是指待为特定治疗的接受者的任何动物(例如,哺乳动物),包括但不限于人、非人灵长类、啮齿类等。通常,提及人受治疗者时术语“受治疗者”和“患者”在本文中可互换使用。
“联合”一种或多种其他治疗剂施用包括同时(同时发生的)和以任何顺序的连续施用。
术语“药物制剂”是指允许活性成分的生物活性有效的形式和不含有对于进行该制剂施用的受治疗者有不能接受的毒性的其他组分的制剂。
本文揭示的抗体的“有效量”是足以实现特别说明的目的的量。根据所说明的目的,“有效量”可经验性且以常规方式来确定。
术语“治疗有效量”是指有效“治疗”受治疗者或哺乳动物的疾病或病症的抗体或其他药物的量。在癌的情况中,药物的治疗有效量可减少癌细胞的数量,减小肿瘤体积,抑制(即,在某种程度上减缓或阻止)癌细胞浸润至周围器官,抑制(即,在某种程度上减缓或阻止)肿瘤转移,在某种程度上抑制肿瘤生长,和/或者某种程度上缓解癌相关的症状。见,本文“治疗”的定义。在药物可防止生长和/或杀伤存在的癌细胞的程度上,可为细胞生长抑制的和/或细胞毒性的。“预防有效量”是指在剂量和持续时间上有效实现所需预防效果需要的量。通常但非必须的,由于预防剂量组疾病前或在基本早期用于受治疗者,预防有效量将小于治疗有效量。
本文使用的词语“标记物”是指直接或间接与抗体缀合以产生“标记的”抗体的可检测化合物或组合物。标记物本身是可检测的(例如,放射性同位素标记物或荧光标记物),或在酶标记物的情况中,可催化可检测的底物化合物或组合物的化学变化。
“化学治疗剂”是一种可用于治疗癌的化学化合物,不管其作用机制是什么。化学治疗剂包括,例如,CD20D的拮抗剂(例如利妥昔单抗和环磷酰胺),多柔比星,长春新碱,泼尼松,氟达拉滨,鬼臼乙叉甙,甲氨喋呤,来那度胺,苯丁酸氮芥,苯达莫司汀和/或这些化学治疗剂的修饰形式。
诸如“治疗(treating或treatment或to treat)”、或“缓解(alleviating或toalleviate)”是指1)治愈、减缓、减轻所诊断的病理状况或病症的症状和/或阻止其进展的治疗措施,和2)预防和/或减慢所靶向的病理状况或病症的发展。因此,需要治疗的那些患者包括已经患有病症的那些,易于患有病症的那些,以及其中有待预防病症的那些。在某些实施方案中,如果患者显示了下列的一种或多种则受治疗者被根据本发明的方法成功“治疗”癌:癌细胞数量减少或完全缺乏,肿瘤大小减小;癌细胞浸润至周围器官受到抑制或缺乏,包括,例如癌播散至软组织和骨骼;肿瘤转移受到抑制或缺乏;肿瘤生长受到抑制或缺乏;与特定癌相关的一种或多种症状减轻;发病率和死亡率减小;生命质量改善;肿瘤的致瘤性、致瘤频率或致瘤能力减小;肿瘤中的癌干细胞的数量或频率减小;致瘤细胞分化为非致瘤状态;或一些效果的组合。

在两个或多个核酸或多肽的上下文中的术语“同一性”或“同一性百分数”是指,当对于最大对应性来比较和比对(如果需要,引入间隙)时(不考虑作为序列同一性部分的任何保守性氨基酸取代),两个或多个序列或亚序列是相同的或者具有相同的核苷酸或氨基酸残基的特定百分数。可使用序列比较软件或算法或通过目测观察来测量同一性百分数。可用于获得氨基酸或核苷酸序列比对的多种算法和软件为本领域已知。序列比对算法的一个这样的非限制性实例描述于Karlin等人,1990,Proc.Natl.Acad.Sci.,87:2264-2268,修改于Karlin等人,1993,Proc.Natl.Acad.Sci.,90:5873-5877,并合并至NBLAST和XBLAST程序中(Altschul等人,1991,Nucleic Acids Res.,25:3389-3402)。在某些实施方案中,可如Altschul等人,1997,Nucleic Acidss Res.25:3389-3402中描述的使用Gapped BLAST。BLAST-2、WU-BLAST-2(Altschul等人,1996,Methods in Enzymology,266:460-480)、ALIGN、ALIGN-2(Genentech,South San Francisco,California)或Megalign(DNASTAR)是可用于进行序列比对的其他可公共获得的软件程序。在某些实施方案中,使用GCG软件中的GAP程序来确定两个核苷酸序列之间的同一性百分数(例如,使用NWSgapdna.CMP矩阵和40、50、60、70或90的间隙加权和1、2、3、4、5或6的长度加权)。在某些可选的实施方案中,并入了Needleman和Wunsch算法(J.Mol.Biol.(48):444-453(1970))的GCG软件包中的GAP程序可用于确定两个氨基酸序列之间的同一性百分数(例如,使用Blossum 62矩阵或PAM250矩阵,和16、14、12、10、8、6或4的间隙加权和1、2、3、4、5的长度加权)。可选地,在某些实施方案中,使用Myers和Miller算法(CABIOS,4:11-17(1989))确定核苷酸或氨基酸序列之间的同一性百分数。例如,可使用ALIGN程序(2.0版)和使用具有残基表的PAM120、间隙长度罚分12和间隙罚分4来确定同一性百分数。本领域技术人员可通过特定比对软件确定用于最大比对的合适参数。在某些实施方案中,使用比对软件的缺省参数。在某些实施方案中,第一氨基酸序列与第二氨基酸序列的同一性百分数“X”被计算为100×(Y/Z),其中,Y是指第一和第二序列的比对中计为完全匹配的氨基酸残基的数目,Z是第二序列中残基的总数。如果第一序列的长度比第二序列长,则第一序列与第二序列的同一性百分数会比第二序列与第一序列的同一性百分数要长。
作为非限制性实例,可在某些实施方案中使用Bestfit程序来确定任何特定的多核苷酸是否与参考序列具有某些序列同一性百分数(例如,至少80%同一性,至少85%同一性,至少90%同一性,以及在某些实施方案中,至少95%、96%、97%、98%或99%同一性)(Wisconsin序列分析包,Unix 8版,Genetics Computer Group,University ResearchPark,575Science Drive,Madison,WI 53711)。Bestfit使用Smith和Waterman,Advancesin Applied Mathematics 2:482 489(1981)的局部同源性算法,来发现两个序列之间具有同源性的最佳片段。当根据本发明使用Bestfit或任何其他序列比对程序来确定特定序列是否与参考序列具有例如95%的同一性时,设定参数,使得经参考核苷酸序列的全长来计算同一性百分数和允许同源性中的间隙达参考序列中核苷酸总数的5%。
在一些实施方案中,本发明的两个核酸或多肽基本上完全同一,意思是,当如使用序列比较算法或通过目测观察测量的那样比较和比对最大对应性时,它们具有至少70%、至少75%、至少80%、至少85%、至少90%且在一些实施方案中具有至少95%、96%、97%、98%、99%的核苷酸或氨基酸残基同一性。同一性可存在于长度为至少约10个、约20个、约40-60个残基或任何整数值的序列区域,并可存在于长于60-80个残基的区域,例如,至少约90-100个残基,在一些实施方案中,序列中所比较的序列的全长是基本上完全同一的,例如核苷酸序列的编码区。
“保守性氨基酸取代”是指其中一个氨基酸残基被具有相似侧链的另一个氨基酸残基取代。具有相似侧链的氨基酸残基的家族在本领域中有定义,包括碱性侧链(例如,赖氨酸,精氨酸,组氨酸),酸性氨基酸(例如,天门冬氨酸,谷氨酸),不带电荷的极性侧链氨基酸(例如,甘氨酸,天门冬酰胺,谷酰胺,丝氨酸,苏氨酸,酪氨酸,半胱氨酸),非极性侧链(例如,丙氨酸,缬氨酸,亮氨酸,异亮氨酸,脯氨酸,苯丙氨酸,甲硫氨酸,色氨酸),β分支侧链(例如,苏氨酸,缬氨酸,异亮氨酸)和芳香族侧链(例如,酪氨酸,苯丙氨酸,色氨酸,组氨酸)。例如,苯丙氨酸取代酪氨酸是保守性取代。在一些实施方案中,本发明的多肽和抗体序列中的保守性取代并不消除含有氨基酸序列的多肽或抗体与抗原结合,所述抗原即所述多肽或抗体结合的CD37。鉴定不消除抗原结合的核苷酸和氨基酸保守性取代的方法为本领域公知(见,例如,Brummell等人,Biochem.32:1180-1 187(1993);Kobayashi等人,ProteinEng.12(10):879-884(1999);以及Burks等人,Proc.Natl.Acad.Sci.USA 94:.412-417(1997))。
除非上下文另有明确指明,本文说明书和权利要求书所使用的单数形式(“a”、“an”以及“the”)包括复数形式。
应理解无论本文何处使用用语“包括”描述实施方案,都还提供以“由……组成”和/或“基本由……组成”描述的类似实施方案。
本文在诸如“A和/或B”的短语中使用的术语“和/或”意指包括“A和B”、“A或B”、“A”以及“B”。同样的,在诸如“A、B和/或C”的短语中使用的术语“和/或”意指包括下列各实施方案:A、B以及C;A、B或C;A或C;A或B;B或C;A和C;A和B;B和C;A(单独);B(单独);以及C(单独)。

在一些实施方案中,CD37结合剂能够减小肿瘤体积。CD37结合剂减小肿瘤体积的能力可通过测量%T/C值来评估,%T/C值是由对照受治疗者的中位数肿瘤体积除被治疗的受治疗者的中位数肿瘤体积。在在一些实施方案中,使用CD37结合剂治疗导致下列%T/C值:小于约55%、小于约50%、小于约45%、小于约40%、小于约35%、小于约30%、小于约25%、小于约20%、小于约15%、小于约10%或小于约5%。在一些特定的实施方案中,CD37结合剂可减小BJAB异种移植物模型和/或SU-DHL-4异种移植物模型中的肿瘤大小。
在某些实施方案中,特异性结合人CD37的免疫缀合物或其他制剂经细胞毒性剂来引发细胞死亡。例如,在某些实施方案中,将人CD37抗体的抗体与美登素缀合,美登素在表达CD37的细胞中通过蛋白质内化而活化。在某些可选的实施方案中,所述制剂或抗体不被缀合。
在某些实施方案中,CD37结合剂能够抑制肿瘤生长。在某些实施方案中,CD37结合剂能够在体外抑制肿瘤生长(例如,在异种移植物模型和/或者患有癌的人中)。

在某些特定实施方案中,CD37结合剂与CD37的结合不需要人CD37氨基酸109-138。因此,一些CD37结合剂结合包含SEQ ID NO:180的氨基酸序列的多肽。在其他实施方案中,CD37结合剂与CD37的结合被人CD37氨基酸202-243的突变中断。因此,一些CD37结合剂不结合包含SEQ ID NO:184的氨基酸序列的多肽。
在一些实施方案中,CD37结合剂结合SEQ ID NO:180的多肽和结合SEQ ID NO:183的多肽,但不结合SEQ ID NO:184的多肽。

可使用杂交瘤方法来制备单克隆抗体,例如Kohler和Milstein(1975)Nature256:495描述的那些。使用杂交瘤方法,如上所述对小鼠、仓鼠或其他合适的宿主动物进行免疫以引发淋巴细胞产生特异性结合免疫抗原的抗体。还可在体外对淋巴细胞进行免疫。在免疫之后,分离淋巴细胞并使用例如聚乙二醇与合适的骨髓瘤细胞系进行融合以形成杂交瘤细胞,然后可将所述杂交瘤细胞与未融合的淋巴细胞和骨髓瘤细胞选择开。然后,可对于产生针对所选择的抗原的单克隆抗体的杂交瘤[如通过免疫沉淀、免疫印迹或通过体外结合测定(例如,放射免疫测定(RIA),酶联免疫吸附测定(ELISA))所检测]使用标准方法体外培养(Goding,Monoclonal Antibodies:Principles and Practice,Academic Press,1986)或在动物中体内作为腹水肿瘤来传代。然后,可如上文对于多克隆抗体所述那样从培养基或腹水瘤体纯化单克隆抗体。
可选地,还可使用如美国专利4,816,567中描述的重组DNA方法来制备单克隆抗体。从成熟B细胞或杂交瘤细胞分离编码单克隆抗体的多核苷酸,例如使用特异性扩增编码抗体的重链和轻链的基因的寡核苷酸引物通过RT-PCR,并且使用常规程序来确定它们的序列。然后,将编码重链和轻链的分离的多核苷酸克隆至合适的表达载体,然后将所述表达载体转染至宿主细胞,例如大肠杆菌(E.coli)细胞、猿猴COS细胞、中国仓鼠卵巢(CHO)细胞,或不产生免疫球蛋白的骨髓瘤细胞,由宿主细胞产生单克隆抗体。另外,可如先前所述从表达所需物种的CDR的噬菌体展示库分离所需物种的重组单克隆抗体或其片段(McCafferty等人,1990,Nature,348:552-554;Clackson等人,1991,Nature,352:624-628;以及Marks等人,1991,J.Mol.Biol.,222:581-597)。
可使用重组DNA技术以许多不同方式进一步修饰编码单克隆抗体的多核苷酸,以产生可选的抗体。在一些实施方案中,例如小鼠单克隆抗体的轻链和重链恒定区可被取代为1)例如人抗体的那些区以产生嵌合抗体或取代为2)非免疫球蛋白多肽以产生融合抗体。在一些实施方案中,将恒定区截短或去除以产生单克隆抗体的所需抗体片段。可变区的位点定向或高密度诱变可用于优化单克隆抗体的特异性、亲和力等。
在一些实施方案中,针对人CD37的单克隆抗体为人源化抗体。在某些实施方案中,当将这样的抗体施用于人受治疗者时,在治疗上将其用于减小减小抗原性和HAMA(人抗小鼠抗体)反应。可使用本领域已知的多种技术来制备人源化抗体。在某些可选的实施方案中,针对CD37的抗体为人抗体。

人源化抗体还可在含有人免疫球蛋白基因座的转基因小鼠中制备,当免疫时所述小鼠能够在不产生外源性免疫球蛋白的情况下产生人抗体的所有组分。该技术描述于美国专利5,545,807;5,545,806;5,569,825;5,625,126;5,633,425;以及5,661,016。
本发明还包括特异性识别CD37的双特异性抗体。双特异性抗体为能够特异性识别并结合至少两个不同表位的抗体。不同表位可位于相同分子中(例如,相同的CD37)或位于不同分子上,使得例如两个抗体均能够特异性识别和结合CD37,以及例如1)白细胞上的效应分子,例如T细胞受体(例如CD3)或Fc受体(例如,CD64、CD32或CD16)或2)如下文详细描述的细胞毒性剂。
示例的双特异性抗体可结合两个不同的表位,其中至少之一源于本发明的多肽。可选地,免疫球蛋白分子的抗抗原臂可与结合白细胞上的触发分子(例如T细胞受体分子(例如CD2、CD3、CD28或B7)或IgG的Fc受体的臂组合,以将细胞防御机制集中于表达特定抗原的细胞。双特异性抗体还可用于将细胞毒性剂针对表达特定抗原的细胞。这些抗体具有抗原结合臂和结合细胞毒性剂或放射性核素螯合剂(例如EOTUBE、DPTA、DOTA或TETA)的臂。制备双特异性抗体的技术为本领域公知(Millstein等人,1983,Nature 305:537-539;Brennan等人,1985,Science 229:81;Suresh等人,1986,Methods in Enzymol.121:120;Traunecker等人,1991,EMBO J.10:3655-3659;Shalaby等人,1992,J.Exp.Med.175:217-225;Kostelny等人,1992,J.Immunol.148:1547-1553;Gruber等人,1994,J.Immunol.152:5368;以及美国专利5,731,168)。还考虑了具有超过两个原子价的抗体。例如,可制备三特异性抗体(Tutt等人,J.Immunol.147:60(1991))。因此,在某些实施方案中,CD37的抗体为多特异性。
在某些实施方案中,提供了用于例如增加肿瘤渗透性的抗体片段。已知用于产生抗体片段的多种技术。传统上,这些片段经对完整抗体进行蛋白水解消化而产生(例如,Morimoto等人,1993,Journal of Biochemical and Biophysical Methods 24:107-117;Brennan等人,1985,Science,229:81)。在某些实施方案中,重组产生抗体片段。Fab、Fv以及scFv抗体片段均可表达或分泌于大肠杆菌或其他宿主细胞,从而允许产生大量这些片段。这样的抗体片段还可从上文讨论的抗体噬菌体库分离。抗体片段还可为例如美国专利5,641,870中描述的直链抗体,且可为单特异性或双特异性。用于产生抗体片段的其他技术对于医学专业人员来说是显而易见的。
根据本发明,多种技术可适于产生CD37的特异性单链抗体(见,美国专利号4,946,778)。另外,多种方法可适于构建Fab表达库(Huse,等人,Science 246:1275-1281(1989))以使得快速和有效鉴定具有所需对于CD37的特异性的单克隆Fab片段或其衍生物、片段、类似物或同系物。可通过本领域的技术来治病抗体片段,包括但不限于(a)通过对于抗体分子进行胃蛋白酶消化产生的F(ab')2片段;(b)通过减少F(ab')2片段的二硫键而产生的Fab片段,(c)通过使用木瓜蛋白酶和还原剂来处理抗体而产生的Fab片段,以及(d)Fv片段。
修饰抗体以增加其血清半衰期也是合乎需要的,特别是在抗体片段的情况下。可通过下述方法实现这点,例如,通过对抗体片段中的合适区域进行突变而将结合补救受体的表位掺入抗体片段,或通过将表位掺入肽标签,然后将所述标签与抗体片段中末端或在中间融合(例如,通过DNA或肽合成)。
异缀合抗体也在本发明的范围内。异缀合抗体由两个共价连接的抗体组成。例如,这样的抗体已经被提出使免疫细胞靶向非期望的细胞(美国专利第4,676,980号)。考虑到了可使用合成蛋白质化学中已知的方法来体外制备抗体,包括涉及接头的那些。例如,可使用二硫键交换反应或通过形成硫醚键来构建免疫毒素。用于该目的的合适试剂的实例包括亚胺硫醇酯和甲基-4-巯基丁基酰亚胺酯。
对于本发明的目的,应理解修饰的抗体可包括提供了抗体与人CD37的多肽缔合的任何类型的可变区。关于这点,可变区可包括或衍生自可被诱导产生体液反应并产生针对所需肿瘤相关抗原的免疫球蛋白的任何类型的哺乳动物。这样,被修饰的抗体的可变区可为例如人、鼠、非人灵长类(例如,短尾猴、猕猴等)或狼来源。在一些实施方案中,被修饰的免疫球蛋白的可变区和恒定区均为人的。在其他实施方案中,相容的抗体的可变区(通常衍生自非人来源)可被工程化或特别修剪以改进结合特性或减轻分子的免疫原性。在该方面,用于本发明的可变区可为人源化或通过包含引入的氨基酸序列而改变。
在某些实施方案中,重链和轻链中的可变结构域可通过一种或多种CDR的至少部分取代和必要时通过部分框架区替换和序列改变而改变。尽管CDR可衍生自与框架区从中衍生的抗体相同的类或甚至亚类的抗体,但认为CDR可衍生自不同类别的抗体并可能衍生自不同物种的抗体。并非总是有必要使用供体可变区的完整CDR来替换所有CDR,以将一个可变结构域的抗原结合能力转变为另一可变结构域的抗原结合能力。相反,在一些情况下,仅需要转换对于维持抗原结合位点的活性必需的那些残基。考虑到美国专利号5,585,089、5,693,761以及5,693,762中提出的解释,通过实施常规实验或通过试验与误差试验来获得具有减轻的免疫原性的功能抗体很好地在本领域技术人员的能力范围内。
尽管对于可变区进行改变,但本领域技术人员应理解本发明的被修饰的抗体将包括下述抗体(例如,全长抗体或其免疫反应性片段),即,其中一个或多个恒定结构域的至少一个级分缺失或被改变以提供所需的生物化学特性,例如当与包含天然或未改变的恒定区的具有近似相同免疫原性的抗体相比时增加的肿瘤定位或减少的血清半衰期。在一些实施方案中,修饰的抗体的恒定区包含人恒定区。适于本发明的恒定区的修饰包括一个或多个结构域中一个或多个氨基酸的添加、缺失或取代。也就是说,本发明揭示的修饰的抗体可包含对于三个重链恒定结构域(CH1、CH2或CH3)的一个或多个和/或对于轻链恒定区(CL)的改变或修饰。在一些实施方案中,考虑到其中一个或多个结构域被部分或完全缺失的修饰的恒定区。在一些实施方案中,修饰的抗体包含结构域缺失的构建体或变体,其中CH2结构域被去除(ΔCH2构建体)。在一些实施方案中,缺失的恒定结构域被短氨基酸间隔区(例如,10个残基)取代,所述短氨基酸间隔区提供通常由所缺乏的恒定区赋予的一些分子柔性。
除了其构象,本领域中已知,恒定区介导几种效应子功能。例如,补体的C1组分与抗体结合激活补体系统。补体的激活在细胞病原体的调理和裂解中是重要的。补体的激活还刺激炎症反应,且还可涉及自身免疫超敏反应。另外,抗体经Fc区结合细胞,抗体Fc区上的Fc受体位点结合细胞上的Fc受体(FcR)。有多个对于不同类型抗体特异性的Fc受体,包括IgG(γ受体)、IgE(η受体)、IgA(α受体)以及IgM(μ受体)。抗体与细胞表面上的Fc受体结合触发了重要的和不同生物反应,包括对于抗体覆盖的颗粒的吞噬和破坏,免疫复合物的清除,杀伤细胞对于抗体覆盖的靶细胞的裂解(被称为抗体依赖性细胞介导的细胞毒性,或ADCC),炎症介质的释放,胎盘转移和免疫球蛋白产生的控制。
在某些实施方案中,CD37结合抗体提供了改变的效应子功能,而改变的效应子功能又影响所施用的抗体的生物学模式。例如,恒定区结构域的缺失或灭活(通过点突变或其他方式)可减弱循环修饰的抗体的Fc受体结合,从而增加肿瘤定位。在其他情况中,可以是,与本发明相一致的,恒定区修饰减弱补体结合并从而减少血清半衰期和缀合的细胞毒素的非特异性缔合。另外,恒定区的其他修饰可用于消除二硫键或寡糖部分,该二硫键或寡糖部分因增加的抗原特异性或抗体柔性而允许提高的定位。相似地,根据本发明对于恒定区的修饰可容易地使用很好地在本领域技术人员的技术范围内的公知的生物化学或分子工程技术来制备。
在某些实施方案中,作为抗体的CD37结合剂不具有一种或多种效应子功能。例如,在一些实施方案中,抗体不具有抗体依赖性细胞毒性(ADCC)活性和/或不具有补体依赖性细胞毒性(CDC)活性。在某些实施方案中,抗体不结合Fc受体和/或补体因子。在某些实施方案中,抗体不具有效应子功能。
应注意,在某些实施方案中,可将修饰的抗体进行工程化来将CH3结构域直接与各修饰抗体的绞链区融合。在其他构建体中,提供位于绞链区和修饰的CH2和/或CH3结构域之间的肽间隔区可以是合乎需要的。例如,合适的构建体可被表达,其中,CH2结构域已缺失,剩下的CH3结构域(修饰的或未修饰的)与具有5-20个氨基酸间隔区的绞链区连接。这样的间隔区可以被例如添加以保证恒定结构域的调节元件仍游离和易接近或保证铰链区仍具有柔性。然而,应注意,在一些情况下,氨基酸间隔区显示具有免疫原性且引发针对构建体的不想要的免疫反应。因此,在某些实施方案中,被添加至构建体的任何间隔区较不具有免疫原性,或甚至完全缺失,以维持修饰的抗体的所需的生物化学性质。
除了整个恒定区结构域缺失以外,应理解所提供的本发明的抗体可为少数或甚至单个氨基酸的部分缺失或取代。例如,在CH2结构域的缺失区域中单个氨基酸突变可足以基本上减弱Fc结合并由此增加肿瘤定位。相似地,仅使得调控待调节的效应子功能(例如,补体CLQ结合)的一个或多个恒定区结构域缺失可以是合乎需要的。这样的恒定区的部分缺失可改善抗体的选择的特性(血清半衰期),同时使得与受治疗者恒定区结构域相关的其他合乎需要的功能完整。另外,如上文提及的,所揭示的抗体的恒定区可通过对于一个或多个氨基酸进行突变或取代而修饰,这可提高所产生的构建体的特性。关于这方面,可能破坏保守结合位点(例如,Fc结合)提供的活性而同时基本上维持修饰的抗体的构象和免疫原性。某些实施方案可包括将一个或多个氨基酸添加至恒定区以提高合乎需要的特性,例如,减小或增加效应子功能或提供较多细胞毒素或碳水化合物附着。在这些实施方案中,插入或复制衍生自所选择的恒定区结构域的特异性序列是合乎需要的。
本发明还包括基本上与本发明提到的嵌合抗体、人源化抗体以及人抗体具有同源性的变体和等同物。这些含有,例如,保守性取代突变,即一个或多个氨基酸被相似的氨基酸取代。例如,保守性取代是指以相同通用分类中的另一氨基酸取代一种氨基酸,例如,以另一种酸性氨基酸取代一种酸性氨基酸,以另一种碱性氨基酸取代一种碱性氨基酸或由另一种中性氨基酸取代一种中性氨基酸。预期的保守性氨基酸取代为本领域公知。
本发明的多肽可以是包含针对人CD37的抗体或其片段的重组多肽、天然多肽或合成多肽。本领域将认识到,本发明的一些氨基酸序列可改变而不会对蛋白的结构或功能产生显著的影响。因此,本发明还包括显示出实质上活性的多肽变体,或其包括针对CD37蛋白的抗体或其片段的区域。这些突变包括缺失、插入、翻转、重复和类型置换。
多肽和类似物可进一步修饰以含有非蛋白通常部分的另外的化学部分。这些衍生的部分可改善蛋白的溶解度、生物半衰期或吸收。所述部分还可以降低或消除蛋白的任何期望的副作用等。这些部分的综述可在REMINGTON'S PHARMACEUTICAL SCIENCES,20thed.,Mack Publishing Co.,Easton,PA(2000)中找到。
本文中所述的分离的多肽可以通过本领域已知的任何合适的方法来制备。这些方法的范围包括从直接蛋白合成方法到构建编码分离的多肽序列的DNA序列,并且在合适的转化的宿主中表达那些序列。在一些实施方案中,DNA序列使用重组技术通过分离或合成编码目标野生型蛋白的DNA序列来构建。任选地,所述序列可通过定点突变来突变,以提供其功能类似物。例如参见Zoeller et al.,Proc.Nat’l.Acad.Sci.USA81:5662-5066(1984)和美国专利No.4,588,585。
在一些实施方案中,编码目标多肽的DNA序列将通过化学合成使用寡核苷酸合成器来构建。这些寡核苷酸可基于期望的多肽的氨基酸序列并选择那些密码子来设计,所述密码子在宿主细胞中是有利的,在所述宿主细胞中将制备目标重组多肽。标准方法可应用于合成编码目标分离的多肽的分离的核苷酸序列。例如,完全氨基酸序列可用于构建反向翻译的基因。另外,可以合成含有核苷酸序列的DNA低聚物,所述核苷酸序列编码用于特定分离的多肽。例如,编码用于部分期望的多肽的一些小寡核苷酸可被合成,并然后连接。各个寡核苷酸典型地含有5'或3'突出端以用于互补装配。
在装配后(通过合成、定点突变或另外方法),编码目标特定分离的多肽的多核苷酸序列将插入表达载体中,并且操作性地连接适于在期望的宿主中表达蛋白的表达控制序列。合适的装配可通过下列方式来证实:核苷酸测序、限制性映射和生物活性多肽在合适宿主中的表达。如本领域已知的,为了在宿主中获得高表达水平的转染的基因,基因必须操作性的连接在选择的表达宿主中具有功能的转录和翻译的达控制序列。
在某些实施方案中,重组表达载体用于扩增和表达编码针对人CD37的抗体或其片段的DNA。重组表达载体是可复制的DNA构建体,其具有编码抗-CD37抗体或其片段的多肽链的合成或cDNA-衍生的片段,其操作性地连接合适的转录和翻译的调节元件(衍生自哺乳动物、微生物、病毒或昆虫基因)。转录单元通常包括下列装配:(1)在基因表达中具有调节作用的一种或多种基因元件,例如转录启动子或增强子;(2)转录到mRNA中并翻译到蛋白中的结构或码序列;以及(3)合适的转录和反应引发和终止序列,如下面详细所述。这些调节元件可包括操纵基因序列以控制转录。可另外地引入的能力,其由复制源和选择基因赋予以促进转化体的识别。当它们功能上彼此关联时,DNA区操作性地连接。例如,信号肽(分泌前导序列)的DNA操作性地连接多肽的DNA,如果其表达为参与多肽分泌的前体;启动子操作性地连接编码序列,如果其控制序列的转录;或核糖体结合位点操作性地连接编码序列,如果其被定位以允许翻译。旨在用在酵母表达系统中的结构元件包括能够通过宿主细胞进行翻译的蛋白的细胞外分泌的前导序列。可选择地,如果在没有前导序列或运输序列的情况下表达重组蛋白,其可包括N-末端蛋氨酸残基。该残基可任选地随后从表达的重组蛋白切除以提供最终产物。
表达控制序列和表达载体的选择取决于宿主的选择。可以使用宽范围的表达宿主/载体的组合。用于真核宿主的有用表达载体包括例如包含来自SV40的表达控制序列的载体、牛乳头瘤病毒、腺病毒和细胞巨化病毒。细菌宿主的有用的表达载体包括已知的细菌质粒,例如来自Esherichia coli的质粒,包括pCR 1、pBR322、pMB9和它们的衍生物;更宽宿主范围的质粒、例如M13和丝状单链DNA噬菌体。
用于表达CD37-结合多肽或抗体(或CD37蛋白以用作抗原)的合适的宿主细胞包括原核细胞、酵母、昆虫或在合适的启动子控制下的高级真核细胞。原核细胞包括革兰氏阴性或革兰氏阳性有机体,例如E.coli或杆菌。高级真核细胞包括如下所示的哺乳动物源的建立的细胞系。也可以使用无细胞翻译体系。用于细菌、真菌、酵母和哺乳动物细胞宿主的合适的克隆和表达载体由Pouwels et al.所述(Cloning Vectors:A Laboratory Manual,Elsevier,N.Y.,1985),并且其相关公开通过引用的方式并入。关于蛋白制备包括抗体制备的方法的另外的信息可以在例如美国专利公开No.2008/0187954、美国专利No.6,413,746和6,660,501、以及国际专利公开No.WO 04009823中找到,其均通过引用的方式全部并入本文中。
各种哺乳动物或昆虫细胞培养物系统也有利地用于表达重组蛋白。重组蛋白在哺乳动物细胞中的表达可进行,因为这些蛋白通常正确地折叠、合适地修饰、并且是完全功能性的。合适的哺乳动物宿主细胞系的例子包括猴肾细胞的COS-7系,其由Gluzman所述(Cell23:175,1981),和能够表达合适的载体的其他细胞系,包括例如L细胞,C127,3T3,中华仓鼠卵巢细胞(CHO),HeLa和BHK细胞系。哺乳动物表达载体可包含非转录的元件,例如复制源、连接待表达的基因的合适的启动子和增强子、以及其他5'或3'侧翼非转录的序列和5'或3'非翻译的序列例如必需核糖体结合位点、多腺苷酸化位点、剪接供体和受体位点、以及转录终止序列。在昆虫细胞中制备异源蛋白的杆状病毒系统由Luckow和Summers综述,Bio/Technology6:47(1988)。
由转化的宿主制备的蛋白可根据合适的方法来纯化。这些标准方法包括色谱法(例如离子交换、亲和和空间柱色谱法)、离心、差式溶解或通过用于蛋白纯化的任何其他标准技术。亲和标签例如六聚组氨酸、麦芽糖结合域、流感覆膜序列和谷胱甘肽-S-转移酶可附接蛋白以允许通过合适的亲和柱来容易地进行纯化。分离的蛋白还可以使用这些的技术来物理标准,所述技术例如蛋白质水解、核磁共振和x-射线结晶学。
例如,来自分泌重组蛋白到培养基中的系统的上清可使用市售蛋白浓缩过滤器例如Amicon或Millipore Pellicon超滤单元首先浓缩。在浓缩步骤后,所得浓缩物可应用于合适的纯化基质。可选择地,可以使用阴离子交换树脂,例如具有侧链二乙基氨基乙基(DEAE)基团的基质或基材。所述基质可以是丙烯酰胺、琼脂糖、葡萄聚糖、纤维素或通常应用在蛋白纯化中的其他类型。可选择地,可以使用阳离子交换步骤。合适的阳离子交换包括各种不溶性基质,包含磺基丙基或羧甲基。最后,可以使用一种或多种反相高效液相色谱法(RP-HPLC)步骤(其利用疏水性RP-HPLC介质例如具有侧链甲基或其他脂肪族基团的硅胶)来进一步纯化CD37-结合剂。上述纯化步骤的一些或全部以多种组合方式还可用于提供同源重组蛋白。
在细菌培养基中制备的重组蛋白可例如通过下列方式进行分离:初始从细胞沉淀物中提取,然后进行一次或多次浓缩,盐析。水性离子交换或空间排阻色谱法步骤。高效液相色谱法(HPLC)可用于最终的纯化步骤。在表达重组蛋白中使用的微生物细胞可通过任何常规方法来破坏,包括冻融循环、超声、机械破坏或使用细胞胞溶剂。
还包括本领域已知的用于纯化抗体和其他蛋白的方法,例如美国专利公开No.2008/0312425、2008/0177048和2009/0187005中所述的那些,其均通过引用的方式全部并入本文中。
在某些实施方案中,CD37-结合剂是非抗体的多肽。鉴定和制备高亲和性地结合蛋白靶的非抗体多肽的多种方法是本领域已知的。例如参见Skerra,Curr.Opin.Biotechnol.,18:295-304(2007),Hosse et al.,Protein Science,15:14-27(2006),Gill et al.,Curr.Opin.Biotechnol.,17:653-658(2006),Nygren,FEBS J.,275:2668-76(2008),和Skerra,FEBS J.,275:2677-83(2008),其均通过引用的方式全部并入本文中。在某些实施方案中,噬菌体显示技术用于鉴定/制备CD37-结合多肽。在某些实施方案中,多肽包含选自由下列构成的组的类型的蛋白支架:蛋白A、脂笼蛋白、纤维连接蛋白域、锚蛋白通用序列重复域和硫氧还蛋白。
在一些实施方案中,制剂是非蛋白分子。在某些实施方案中,制剂是小分子。用在鉴定非蛋白CD37-结合剂中的组合化学库和技术是本领域技术人员已知的。参见例如Kennedy et al.,J.Comb.Chem,10:345-354(2008),Dolle et al,J.Comb.Chem.,9:855-902(2007)和Bhattacharyya,Curr.Med.Chem.,8:1383-404(2001),其均通过引用的方式全部并入本文中。在某些进一步实施方案中,制剂是碳水化合物、粘多糖、醣蛋白或蛋白多糖。
在某些实施方案中,制剂是核酸适体。适体是多核苷酸分子,其基于它们结合另外分子的能力来选择(例如来自随机或突变库)。在一些实施方案中,适体包含DNA多核苷酸。在某些可选择的实施方案中,适体包含RNA多核苷酸。在某些实施方案中,适体包含一种或多种修饰的核酸残基。产生和筛选用于结合蛋白的核酸适体的方法是是本领域熟知的。例如参见美国专利No.5,270,163,美国专利No.5,683,867,美国专利No.5,763,595,美国专利No.6,344,321,美国专利No.7,368,236,美国专利No.5,582,981,美国专利No.5,756,291,美国专利No.5,840,867,美国专利No.7,312,325,美国专利No.7,329,742,国际专利公开No.WO 02/077262,国际专利公开No.WO 03/070984,美国专利申请公开No.2005/0239134,美国专利申请公开No.2005/0124565和美国专利申请公开No.2008/0227735,其均通过引用的方式全部并入本文中。
III.免疫缀合物
本发明还涉及缀合物(本文中也称为免疫缀合物),包含连接或缀合的药物或前药的本文中公开的抗-CD37抗体、抗体片段和它们的功能等效物。合适的药物或前药是本领域已知的。药物或前药可以是细胞毒素剂。用在本发明的细胞毒素的缀合物中的细胞毒素剂可以是任何这样的化合物,该化合物导致细胞死亡或诱导细胞死亡,或以一些方式降低细胞生存力,并且包括例如美登醇和美登醇类似物。其他合适的细胞毒素剂例如苯二氮卓类、紫杉烷、CC-1065、CC-1065类似物、倍癌霉素和倍癌霉素类似物、紫杉化合物例如刺孢霉素、多拉司他汀和多拉司他汀类似物包括auristatin、托马霉素衍生物、来普霉素衍生物、甲氨蝶呤、顺铂、卡铂、柔红霉素、阿霉素、长春新碱、长春碱、美法仓、丝裂霉素C、苯丁酸氮芥和吗啉代阿霉素。
这些缀合物可通过使用连接基团来制备,以使药物或前药连接至抗体或功能等效物。合适的连接基团是本领域熟知的,并且包括例如二硫化物基团、硫醚基、酸不稳定性基团、光不稳定性基团、肽酶不稳定性基团、和酯酶不稳定性基团。
药物或前药可以例如通过该二硫键连接抗-CD37抗体或其片段。接头分子(linkermolecule)或交联剂(crosslinking agent)包含可和抗-CD37抗体或其片段反应的反应性化学基团。用于和细胞-结合剂反应的反应性化学基团可以是N-琥珀酰亚胺基酯和N-磺基琥珀酰亚胺基酯。另外,接头分子包含反应性化学基团,其可以是可和药物反应以形成二硫键的二硫吡啶基。接头分子包括例如N-琥珀酰亚胺基3-(2-吡啶基二硫代)丙酸酯(SPDP)(例如参见Carlsson et al.,Biochem.J.,173:723-737(1978)),N-琥珀酰亚胺基4-(2-吡啶基二硫代)丁酸酯(SPDB)(例如参见美国专利No.4,563,304),N-琥珀酰亚胺基4-(2-吡啶基二硫代)2-磺基丁酸酯(磺基-SPDB)(参见美国公开No.20090274713),N-琥珀酰亚胺基4-(2-吡啶基二硫代)戊酸酯(SPP)(例如参见CAS注册号341498-08-6),2-亚氨基硫烷,或乙酰琥珀酸酸酐。例如,抗体或细胞结合剂可以使用交联试剂(crosslinking reagent)和含有游离或保护的巯基的抗体或细胞结合剂来修饰,并因此然后衍生,和二硫化物或含巯基的美登醇反应以制备缀合物。缀合物可以通过色谱法纯化,包括但不限于HPLC、空间排阻、吸附、离子交换和亲和捕获、渗析或切向流过滤。
在本发明的另一方面,抗-CD37抗体通过二硫键和聚乙二醇间隔物连接细胞毒素的药物以增强免疫缀合物的效价、溶解度或效力。这些可裂解亲水性接头在WO2009/0134976中有所描述。该接头设计的附加优点是抗体-药物缀合物的期望的高单体比例和最低聚集。该方面中具体涵盖通过二硫化物基团(-S-S-)连接的细胞-结合剂和药物的缀合物,其具有聚乙二醇间隔物((CH2CH2O)n=1-14),药物负载数在2-8的较窄范围,这描述了其对于癌症细胞显示出相对较高有效的生物活性,并且具有高缀合率和高单体比例的期望的生物化学性能,同时具有最小蛋白聚集。
该方面中具体涵盖式(I)的抗-CD37抗体药物缀合物或式(I')的缀合物:
CB–[Xl–(–CH2–CH2O–)n–Y–D]m (I)
[D-Y-(–CH2–CH2O–)n–Xl]m-CB (I')
其中:
CB表示抗-CD37抗体或片段;
D表示药物;
X表示通过硫醚键、酰胺键、氨基甲酸酯键或醚键附接细胞-结合剂的脂肪族、芳香族或杂环单元;
Y表示通过二硫键附接药物的脂肪族、芳香族或杂环单元;
l是0或1;
m是2至8的整数;以及
n是1至24的整数。
在一些实施方案中,m是2至6的整数。

一些缀合物的结构示意图如下所示:
制备这些抗体-美登醇缀合物的一些描述提供在美国专利No.6,333,410,6,441,163,6,716,821和7,368,565中,其全部并入本文中。
通常,抗体在水性缓冲液中的溶液可和过量摩尔数的美登醇一起孵育,所述美登醇二硫化物部分(其具有反应性基团)。反应混合物可通过加入过量的胺(例如乙醇胺、牛磺酸等)淬火。美登醇-抗体缀合物然后可通过凝胶过滤纯化。

实施例1
鼠CD37抗体的制备
构建表达质粒pSRa-CD37,其含有侧翼为XbaI和BamHI限制性内切位点的全部CD37编码序列(CDS),这允许人CD37的表达。300-19细胞,一种衍生自Balb/c小鼠的前B细胞系(M.G.Reth et al.1985,Nature,317:353-355),使用该表达质粒转染以稳定地在细胞表面上表达高水平的人CD37,并且用于免疫Balb/c VAF小鼠。每2-3周通过ImmunoGen,Inc.使用的标准免疫方案使用约5x106CD37-表达300-19细胞/小鼠来进行小鼠皮下免疫。免疫的小鼠在被牺牲以用于杂种瘤生殖之前三天用另一剂量的抗原来进行加强。根据标准动物方案来收集来自小鼠的脾脏,并且放置在两块无菌磨砂显微镜载玻片之间,以获得在RPMI-1640培养基中的单一细胞混悬。将脾细胞粒状沉淀,洗涤,并通过使用聚乙二醇-1500(Roche783 641)和鼠骨髓瘤P3X63Ag8.653细胞融合(J.F.Kearney et al.1979,J Immunol,123:1548-1550)。将融合细胞重悬浮在含有次黄嘌呤-氨基蝶呤-胸苷(HAT)(Sigma H-0262)的RPMI-1640选择培养基中,并且选择用于在37℃下和5%CO2在96-孔平底培养板(Corning-Costar 3596,200μL的细胞混悬液/孔)中生长。在孵育5天后,将100μL的培养上清从各孔中移除,并且用100μL的RPMI-1640培养基来代替,所述培养基含有次黄嘌呤-胸苷(HT)补充物(Sigma H-0137)。继续在37℃下和5%CO2的孵育,直到杂种瘤克隆准备用于抗体筛选。还可以使用免疫和杂种瘤制备的其他技术,包括J.Langone and H.Vunakis(Eds.,Methods inEnzymology,Vol.121,"Immunochemical Techniques,Part I";Academic Press,Florida)和E.Harlow and D.Lane("Antibodies:A Laboratory Manual";1988;Cold SpringHarbor Laboratory Press,New York)中所述的那些。
杂种瘤筛选和选择
来自杂种瘤的培养上清通过流式细胞术筛选以用于分泌小鼠单克隆抗体,所述抗体结合CD37-表达300-19细胞,但不结合非转染的300-19细胞。将100μl的杂种瘤上清和CD37-表达300-19细胞或非转染的300-19细胞(1x105细胞/样品)在100μL FACS缓冲液(RPMI-1640培养基,补充2%正常山羊血清)中孵育3h。然后,将细胞粒状沉淀,洗涤,并且和100μL的PE-缀合的山羊抗-小鼠IgG-抗体(Jackson Laboratory,在FACS缓冲液中6μg/mL)孵育1h。再次将细胞粒状沉淀,使用FACS缓冲液洗涤,并且重悬浮在200μL的含有1%的甲醛的PBS中。使用具有HTS多孔取样器或FACS阵列流式细胞仪的FACSCalibur流式细胞仪来获取样品,并且使用CellQuest Pro(都来自BD Biosciences,San Diego,US)来进行分析。
测试阳性的杂种瘤克隆通过有限稀释被亚克隆。一种来自各杂种瘤的亚克隆(通过流式细胞术这显示出和亲本细胞相同的针对CD37的反应性)被选择用于随后的分析。稳定的亚克隆被培养,并且各分泌的抗-CD37抗体的同种型使用市售同种型试剂(Roche1493027)来鉴定。
在该研究器件内进行总共45个单独的融合试验。单一融合试验惯例产生约200至1000个杂种瘤克隆。通过流式细胞术筛选所有所得杂种瘤克隆用于CD37结合,并且总共184个杂种瘤克隆显示出对于CD37的特异性结合。
抗体纯化
使用标准方法例如蛋白A或G色谱法(HiTrap蛋白A或G HP,1mL,AmershamBiosciences)将抗体从杂种瘤亚克隆上清纯化。简言之,通过加入1/10体积的1M Tris/HClbuffer,pH 8.0,上清被准备用于色谱法。将pH-调节的上清通过0.22μm过滤膜过滤,并且上载到使用结合缓冲液(PBS,pH7.3)平衡的柱上。将柱用结合缓冲液洗涤,直到获得稳定的基线,并且在280nm处无吸收。使用含有0.15M NaCl的0.1M乙酸缓冲液(pH 2.8)、利用0.5mL/min的流速来洗脱抗体。收集约0.25mL的部分,并且通过加入1/10体积的1M Tris/HCl,pH8.0来中和。将峰值部分针对1x PBS整夜透析两次,并且通过0.2μm过滤膜过滤来灭菌。通过在A280的吸光度来定量纯化的抗体。
蛋白A纯化的部分使用离子交换色谱法(IEX)利用季铵(Q)色谱法进一步精制以用于鼠抗体。简言之,来自蛋白A纯化的样品被缓冲液交换到结合缓冲液(10mM Tris,10mM氯化钠,pH 8.0)中,并且通过0.22μm过滤器过滤。然后,制备的样品以120cm/hr的流速上载到用结合缓冲液平衡的Q快速流动树脂(GE Lifesciences)上。柱的尺寸被选择为具有足够的能力以结合样品中所有的MAb。然后将柱用结合缓冲液洗涤,直到获得稳定的基线,并且在280nm处无吸收。通过初始化在20柱体积(CV)中10mM至500mM氯化钠的梯度来洗脱抗体。基于在280nm(A280)处测量的吸光度来收集峰值部分。使用空间排阻色谱法(SEC)在具有SWXLguard柱,6.0×40mm(Tosoh Bioscience,Montgomeryville,PA)的TSK凝胶G3000SWXL,7.8×300mm上、利用Agilent HPLC 1100system(Agilent,Santa Clara,CA)来估计单体的百分率。将单体含量高于95%的部分集中,并且使用TFF体系缓冲液交换至PBS(pH 7.4),然后通过0.2μm过滤膜过滤来灭菌。纯化的抗体的IgG浓度使用1.47的消光系数通过A280来确定。可替换的方法例如陶瓷羟基磷灰石(CHT)也用于精制抗体具有良好的选择性。利用用于IEX色谱法所述的类似的方案来使用具有40μm粒径的II型CHT树脂(Bio-Rad Laboratories)。用于CHT的结合缓冲液对应于20mM磷酸钠,pH 7.0,并且抗体在20CV上使用20-160mM磷酸钠的梯度来洗脱。
实施例2
通过流式细胞术进行结合表征
通过流式细胞术使用纯化的抗体来测试结合特异性。FACS柱状图证实muCD37-3,muCD37-12,muCD37-38,muCD37-50,muCD37-51,muCD37-56和muCD37-57结合CD37-表达300-19细胞,并且在图1和图2中示出缺乏与亲本300-19细胞的结合。所有鼠抗体和CD37-表达300-19细胞或非转染的300-19细胞(1x105细胞/样品)在100μL FACS缓冲液(RPMI-1640培养基,补充2%正常山羊血清)中孵育3h。然后,将细胞粒状沉淀,洗涤,并且和100μL的FITC-缀合的山羊抗-小鼠IgG-抗体(Jackson Laboratory,在FACS缓冲液中6μg/mL)孵育1h。再次将细胞粒状沉淀,使用FACS缓冲液洗涤,并且重悬浮在200μL的含有1%的甲醛的PBS中。使用具有HTS多孔取样器或FACS阵列流式细胞仪的FACSCalibur流式细胞仪来获取样品,并且使用CellQuest Pro(都来自BD Biosciences,San Diego,US)来进行分析。
和muCD37-3,muCD37-12,muCD37-38,muCD37-50,muCD37-51,muCD37-56或muCD37-57孵育的CD37-表达300-19细胞的FACS柱状图显示出荧光偏移,而亲本300-19细胞则不会。此外,当细胞系仅和FITC-缀合的山羊抗-小鼠IgG-抗体单独孵育时,未检测到明显的荧光偏移(图1的底部)。
为了证实抗体也可以结合内生地表达的CD37,使用CD37-阳性WSU-DLCL-2淋巴瘤细胞和muCD37-3,muCD37-12,muCD37-8,muCD37-10或muCD37-14抗体来进行结合试验。将WSU-DLCL-2细胞和改变浓度的鼠抗体孵育,并如上所述处理用于流式细胞术分析。数据分析使用CellQuest Pro(BD Biosciences,San Diego,US)来进行,并且对于各样品,FL1的平均荧光强度(MFI)输出,并且在半-log图中针对抗体浓度绘制(图3)。通过非线性回归来产生剂量-响应曲线,并且各曲线的EC50值,其对应于各抗体的表观解离常数(Kd),使用GraphPad Prism v4(GraphPad软件,San Diego,CA)来计算。对于所有测试的抗体都观察到荧光的强烈偏移,并且Kd值分别对应于0.52nM,1.7nM,2.7nM,1.1nM或0.91nM的muCD37-3,muCD37-8,muCD37-10,muCD37-12或muCD37-14抗体。
同样,当CD37-阳性BJAB淋巴瘤细胞用于上述相同的流式细胞术测定时,也观察到强烈结合。如上所述计算Kd值,并且分别对应于0.2nM,0.4nM,0.6nM,0.4nM和1nM的muCD37-3,muCD37-38,muCD37-50,muCD37-51,muCD37-56和muCD37-57。
实施例3
鼠抗体的促凋亡活性
鼠抗-CD37抗体诱导Ramos和Raji淋巴瘤细胞系的细胞凋亡。在使用膜联蛋白-V(Invitrogen)的FITC缀合物和使用TO-PRO-3(Invitrogen)染色后,通过流式细胞术分析来测量细胞凋亡的程度。在健康正常的细胞中,磷脂酰丝氨酸表达在细胞膜双层的内部,磷脂酰丝氨酸从质膜的内部小叶转移至外部小叶是一种细胞凋亡的最早可检测的信号。膜联蛋白V结合外部上的磷脂酰丝氨酸,但在完整细胞的细胞膜双层的内部上不是这样。因此,膜联蛋白V结合的程度是诱导细胞凋亡的指示。TO-PRO-3是单体菁核酸染色剂,其仅当膜的完整性破坏时(发生在细胞凋亡的后期)才可穿透质膜。在双色流式细胞术中鉴别三种种群的细胞:非-细胞凋亡的细胞(膜联蛋白-V阴性和TO-PRO-3阴性)、早期细胞凋亡的细胞(膜联蛋白-V阳性和TO-PRO-3阴性)和坏死细胞或晚期细胞凋亡的细胞(膜联蛋白-V阳性和TO-PRO-3阳性)。
以指数方式生长的细胞在24-孔板中的RMPI-1640培养基中以约2x105细胞/mL平板接种,所述培养基补充10%胎牛血清(FBS),2mM L谷氨酰胺和50μg/mL庆大霉素(下文中称为完全RMPI-1640培养基)。细胞通常生长在完全RMPI-1640培养基中,除非另有说明。细胞和10nM的抗-CD37抗体在37℃下在加湿5%CO2孵育器中孵育20至24h。然后将细胞粒状沉淀,使用500μl PBS洗涤两次,重悬浮在100μL结合缓冲液(10mM Hepes-NaOH,pH 7.4,140mMNaCl,2.5mM CaCl2)中,使用5μL的膜联蛋白V–FITC在冰上染色15min。然后,将具有1μM的TO-PRO-3的400μL的结合缓冲液加入混合物中,并且通过流式细胞术立即测量FITC和TO-PRO-3的细胞-相关的荧光度。对于各样品收集五千个事件。使用BD CellQuest软件来产生TO-PRO-3(FL4-H;y-轴)和膜联蛋白V-FITC的荧光度(FL1-H;x-轴)的散点图。
从这些图测定各样品的膜联蛋白-V阳性细胞(包括TO-PRO-3阳性和阴性细胞)的百分率,并且对于Ramos细胞示于图4中。分离自我们抗体筛选的数种抗体被测试和利妥昔单抗相比的促凋亡活性。未预料到的是,一些分离的鼠抗-CD37抗体例如muCD37-3和muCD37-12显示出非常强的促凋亡活性。约39%的暴露于muCD37-3的Ramos细胞和46%的暴露于muCD37-12的Ramos细胞是膜联蛋白-V阳性。相反,使用抗-CD20抗体利妥昔单抗处理导致只有13%的膜联蛋白-V阳性细胞,而未处理的对照样品含有5%膜联蛋白-V阳性细胞。分离的鼠抗-CD37抗体中的一些不显示出任何促凋亡活性。例如,相比于未处理的细胞,使用muCD37-8,muCD37-10或muCD37-14处理Ramos细胞导致膜联蛋白-V阳性的百分率微小增加或不增加。这是尽管它们的与CD37的可比得上的结合亲和性,如图3中可见。
另外的抗体被分离和筛选它们在Ramos细胞中诱导细胞凋亡的能力。在多种分离的以高亲和性结合CD37的抗体中,只有一些具有促凋亡活性。膜联蛋白-V测定的结果示于图4B。鼠抗体muCD37-38,muCD37-50,muCD37-51,muCD37-56和muCD37-57能够诱导细胞凋亡,并导致38–45%的膜联蛋白-V阳性Ramos细胞,相比的是在未处理的对照样品中为5%。类似于之前的测试,使用抗-CD20抗体利妥昔单抗处理导致只有18%的膜联蛋白-V阳性细胞。
另外,鼠抗体被测试它们在Raji淋巴瘤细胞中诱导细胞凋亡的能力。如对于Ramos细胞所观察的,在多种分离的以高亲和性结合CD37的抗体中,只有一些具有促凋亡活性。使用muCD37-3或muCD37-12处理分别导致36%或49%的膜联蛋白-V阳性细胞。相反,使用抗-CD20抗体利妥昔单抗处理导致只有20%的膜联蛋白-V阳性细胞,而未处理的对照样品含有4%的膜联蛋白-V阳性细胞。
同样,相比较于15%的未处理的细胞,使用muCD37-3,muCD37-38,muCD37-50,muCD37-51,muCD37-56或muCD37-57处理的约60%的Raji细胞是膜联蛋白-V阳性细胞。
实施例4
增殖测试
抗-CD37抗体抑制细胞生长的能力使用体外细胞毒性测试来测量。将靶细胞以5,000细胞/孔平板接种在100μL的完全RPMI培养基中(RPMI-1640,10%胎牛血清,2mM谷氨酰胺,1%青霉素-链霉素,所有试剂来自Invitrogen)。使用3-倍稀释系列将抗体稀释到完全RPMI培养基中,并且每孔加入100μL。最终浓度典型地为3x 10-8M至4.6x 10-12M。将细胞在37℃下在加湿5%CO2孵育器中孵育4至5天。保留细胞的生存力通过比色WST-8测定(DojindoMolecular Technologies,Inc.,Rockville,MD,US)来确定。WST-8通过活细胞中的脱氢酶还原成在组织培养基中可溶的橙色甲臜产物。甲臜产物的量直接成比例于活细胞的数量。将WST-8加入10%的最终体积中,并且将板在37℃下在加湿5%CO2孵育器中孵育另外2-4小时。通过在多孔板读取器中测量450nm(A450)处的吸光度来分析板。具有培养基和WST-8的孔的背景A450吸光度仅从所有值中减去。%生存力通过使各处理的样品值除以具有未处理的细胞的孔的平均至来计算。%生存力=100*(A450处理的样品–A450背景)/(A450未处理的样品–A450背景)。对于各处理在半-log图中,%生存力值针对抗体浓度绘制。
来自使用鼠CD37抗体和SU-DHL-4淋巴瘤细胞的典型增殖测试的结果展示于图5。明显的是数种鼠抗体能够基本上和以剂量依赖性方式抑制SU-DHL-4细胞的增殖,而其他者没有这种效果。例如,在测试的最高抗体浓度下,使用muCD37-3处理降低细胞生存力至34%,EC50为0.17nM。类似地,在测试的最高抗体浓度下,使用muCD37-38降低细胞生存力至25%,EC50为0.19nM。同样,在测试的最高抗体浓度下,使用muCD37-50或muCD37-51处理降低细胞生存力至38%,EC50分别为0.25nM或0.5nM。相反,使用例如CD37-16处理不会以剂量依赖性方式降低细胞生存力。
实施例5
CD37-3抗体的VL和VH区的克隆和测序
根据制造商的方案,使用RNeasy试剂盒(QIAgen)从CD37-3杂种瘤的5x 106细胞来制备总细胞RNA。cDNA随后从总RNA使用SuperScript II cDNA合成试剂盒(Invitrogen)合成。
在衍生自杂种瘤细胞的cDNA上进行第一轮简并PCR反应的步骤基于Wang et al.((2000)J Immunol Methods.233:167-77)和Co et al.((1992)JImmunol.148:1149-54)中所述的方法。VH序列通过PCR使用下列简并引物来扩展:EcoMH1 CTTCCGGAATTCSARGTNMAGCTGSAGSAGTC(SEQ ID NO:171),EcoMH2 CTTCCGGAATTCSARGTNMAGCTGSAGSAGTCWGG(SEQ IDNO:172)和BamIgG1 GGAGGATCCATAGACAGATGGGGGTGTCGTTTTGGC(SEQ ID NO:173)。VL序列通过PCR使用下列简并引物来扩增:SacIMK GGAGCTCGAYATTGTGMTSACMCARWCTMCA(SEQ ID NO:174)和HindKL TATAGAGCTCAAGCTTGGATGGTGGGAAGATGGATACAGTTGGTGC(SEQ ID NO:175)。(混合的碱基定义如下:N=G+A+T+C,S=G+C,Y=C+T,M=A+C,R=A+G,W=A+T)。PCR反应混合物然后运行在1%低熔点琼脂糖凝胶上,300至400bp带被切除,使用Zymo DNA小柱纯化,并且发送至Agencourt Biosciences以用于测序。各自5’和3’PCR引物用作测序引物以从两个方向产生可变区cDNA。VH和VL区的氨基酸序列从DNA测序结果来预计。
由于用于克隆VL和VH cDNA序列的简并引物改变5’端序列,因此需要另外的测序努力来证实完全序列。初步cDNA序列用于检索NCBI IgBlast网站(http:// www.ncbi.nlm.nih.gov/igblast/),以用于鼠种系序列,从该序列衍生抗体序列。PCR引物然后被设计为退火至鼠抗体的种系连接的前导序列,使得该新PCR反应将产生完全可变区cDNA序列,未被PCR引物改变。PCR反应、带的纯化和测序如上所述进行。
序列证实的质谱确定
可变区的cDNA序列信息联合种系恒定区序列以获得全长抗体cDNA序列。然后,重链和轻链的分子量被计算,并且比较于通过鼠CD37-3抗体的LC/MS分析而获得的分子量。对于CD37-3轻和重链,分子量测量情况一致于cDNA序列。
嵌合
轻链可变区的可变序列克隆到pchCD37-3LCZ质粒中的EcoRI和BsiWI位点中。重链可变区克隆到pchCD37-3HCN质粒中的HindIII和Apa1位点中。等同质粒被构建用于chCD37-12。这些质粒用于使用标准磷酸钙方法(BD Biosciences,CalPhos MammalianTransfection Kit,Cat#631312)来表达HEK-293T细胞中的嵌合抗体。上清使用上述标准蛋白A色谱法纯化,但是精制色谱步骤使用羧甲基(CM)快速流动离子交换(IEX)树脂(GELifesciences)和10mM磷酸钾,10mM氯化钠结合缓冲液(pH 7.5)或者上述可替换的CHT法来进行。

CD37-3和huCD37-50抗体根据前述再表面化方法来人源化,例如Roguska et al.,Proc.Natl.Acad.Sci.,USA,91(3):969-973(1994)和Roguska et al.,Protein Eng.9(10):895-904(1996),其通过引用的方式全部并入本文中。再表面化法通常包括鉴定轻和重链中的可变区框表面残基,并且使用人等同物置换它们。鼠CDR保存在再表面化的抗体中。CD37-3和CD37-50的示例性CDR限定为表11中所指示。除了用于再表面化的重链CDR2定义,所述表提供鼠和人CD37-3和CD37-50的示例性Kabat定义的重链CDR2。。带下划线的序列标记Kabat重链CDR2的不被认为用于再表面化的CDR的部分。
表11
定义用于再表面化的CD37-3和CD7-50轻和重链CDR通过表11中的例子的方式给出。鼠CD37-50轻链CDR2中的赖氨酸53被人源化CD37-50中的天冬酰胺置换(斜体示出),因此给出LC CDR2的两种版本。重链CDR2的Kabat定义也给出用于鼠和人CD37-3。带下划线的序列标记Kabat重链CDR2的不被认为用于再表面化的CDR的部分。
表面残基位被定义为其相对可接近性为30%或更高的任何位(PedersenJ.T.et.Al,J.Mol.Biol.1994;235:959-973)。然后表面残基和人种系表面序列进行比对,以鉴定最同源的人表面序列。对于CD37-3,用作置换表面的人种系序列是IGKV1/OR2-0*01和IGHV4-34*09(分别对于VL和VH)。对于CD37-50,用作置换表面的人种系序列是IGKV3/OR2-268*01和IGHV4-31*03(分别对于VL和VH)。如从图6的列表可见,轻链中总共7个表面残基和重链中7个残基被CD37-3中的人负体置换。如图7中对于CD37-50可见,被人负体置换的总表面残基对于VL和VH分别是7个和5个。在CD37-3中,重链残基61最邻近CDR-H2,并且由于其置换人残基脯氨酸可导致降低的结合亲和性,第二再表面化的版本使用保留的鼠丝氨酸残基来产生。由于这些抗体被测试为细胞毒素的缀合物,因此CD37-50轻链CDR2赖氨酸53被天冬酰胺置换以避免关注赖氨酸缀合可能影响结合亲和性。图8示出轻链和重链的CD37-3和CD37-50可变域的再表面化的序列和它们鼠负体的比对。
huCD37-3抗体的重组表达
huCD37-3和CD37-50的可变区序列被密码子-优化,并且通过Blue HeronBiotechnology合成。序列侧翼有限制性内切酶位点以使用单链哺乳动物表达质粒中各自恒定序列来进行框内克隆。轻链可变区克隆到pAbKZeo质粒中的EcoRI和BsiWI位点。重链可变区克隆到pAbG1Neo质粒中的HindIII和Apa1位点。这些质粒可用于以瞬时或稳定哺乳动物细胞转染表达重组抗体。瞬时转染以在HEK 293T细胞中表达重组抗体使用改善的PEI方法来进行(Durocher,Y.et al.,Nucleic Acids Res.30:E9(2002))。上清通过蛋白A和精制色谱步骤使用上述用于嵌合抗体的标准方法来进行纯化。
TRU-016的表达
为了比较分离的抗-CD37抗体的活性,将之前鉴定的抗-CD37抗体克隆和表达。用于抗-CD37 SMIP的DNA序列使用SEQ ID 51得自US2007/0059306。序列侧翼有HindIII和Xho1限制性内切酶位点以克隆到pAbG1Neo哺乳动物表达质粒。如上面用于huCD37-3所述来进行表达和纯化。

嵌合抗体的结合亲和性
嵌合抗体chCD37-3和chCD37-12被测定和它们鼠负体相比,它们和Ramos细胞的结合亲和性。如实施例2中所述,利用二次FITC-缀合的山羊-抗-鼠和-抗-人抗体,使用Ramos细胞和muCD37-3,chCD37-3,muCD37-12与chCD37-12抗体的流式细胞术结合测试被进行和分析。图9A示出对于各抗体通过非线性回归产生的剂量-响应曲线。各抗体的表观解离常数(Kd)的数值使用GraphPad Prism v4(GraphPad software,San Diego,CA)来计算。明显的是,嵌合并未明显影响抗体的结合亲和性,因为muCD37-3,chCD37-3,muCD37-12和chCD37-12的Kd分别对应于0.4nM,0.8nM,0.8nM和1.2nM。
huCD37-3v1.0和huCD37-3v1.01的结合亲和性
使用BJAB细胞和竞争结合样式的流式细胞术结合测试用于评价CD37-3的嵌合和人源化版本的结合亲和性。BJAB细胞和1nM浓度的PE-标记的muCD37-3抗体孵育,并且通过添加变化量的muCD37-3,chCD37-3,huCD37-3v1.0或huCD37-3v1.01来测量竞争性。样品在4℃下孵育3小时。然后,将细胞粒状沉淀,使用FACS缓冲液洗涤,并且重悬浮在200μL的含有1%的甲醛的PBS中。使用具有HTS多孔取样器的FACSCalibur流式细胞仪来获取样品,并且使用CellQuest Pro(都来自BD Biosciences,San Diego,US)来进行分析。所得平均PE荧光值针对在半-log图中使用的竞争抗体的量进行绘制。图9B示出对于各抗体通过非线性回归产生的剂量-响应曲线。各抗体的表观解离常数(Kd)的数值使用GraphPad Prism v4(GraphPad software,San Diego,CA)来计算。明显的是,嵌合或人源化并未影响CD37-3的结合亲和性,因为所有版本平等地良好竞争和鼠亲本抗体的结合。muCD37-3,chCD37-3,huCD37-3v1.0或huCD37-3v1.01的竞争结合的EC50分别对应于0.8nM,0.7nM,1nM和0.6nM。
人源化抗体的结合亲和性
人源化抗体huCD37-38,huCD37-50,huCD37-51,huCD37-56和chCD37-57被测定和它们鼠负体相比,它们和BJAB细胞的结合亲和性。利用二次FITC-缀合的山羊-抗-鼠和-抗-人抗体进行流式细胞术结合测试,并且如实施例2中所述进行分析,对于各抗体通过非线性回归产生的剂量-响应曲线。各抗体的表观解离常数(Kd)的数值使用GraphPad Prism v4(GraphPad software,San Diego,CA)来计算。明显的是,人源化并不明显影响任何抗体的结合亲和性。muCD37-3和huCD37-3的Kd对应于0.2nM,而muCD37-38和huCD37-38的Kd分别对应于0.4nM和0.3nM。类似地,muCD37-50和huCD37-50的Kd分别对应于0.6nM和0.2nM,而muCD37-51和huCD37-51的Kd分别对应于0.6nM和0.8nM。最后,muCD37-56和huCD37-56的Kd分别对应于0.4nM和0.2nM,而muCD37-57和huCD37-57的Kd分别对应于1.0nM和0.3nM。
实施例8
猕猴CD37的表达
猕猴CD37的CD37 AA序列得自Genbank(GI:718718)。所述序列通过Blue HeronBiotechnology密码子-优化和合成。表达质粒pSRa-CD37mac被构建,其含有来自猕猴的完整CD37编码序列(CDS),其侧翼有XbaI和BamHI限制性内切位点,这允许猕猴CD37的表达。300-19细胞,一种衍生自Balb/c小鼠的前B细胞系(M.G.Reth et al.1985,Nature,317:353-355),使用该表达质粒转染以在细胞表面上稳定地表达猕猴CD37。
鼠抗体与猕猴CD37的结合亲和性
鼠抗体muCD37-3,muCD37-12,muCD37-38,huCD37-50,muCD37-51,muCD37-56和muCD37-57被测定它们结合300-19/CD37mac细胞表达猕猴CD37的能力。使用二次FITC-缀合的山羊-抗-鼠或山羊-抗-人抗体来进行流式细胞术结合测试,并且如实施例2中所述进行分析。结合比较于之前描述的抗-CD37抗体WR17和抗-CD37 SMIP TRU-016。如图10A中可见,数种分离的抗-CD37抗体,muCD37-38,huCD37-50,muCD37-51,muCD37-56和muCD37-57可结合猕猴衍生的CD37抗原。相反,muCD37-3,muCD37-12,之前描述的抗-CD37抗体WR17和抗-CD37 SMIP TRU-016不能结合猕猴衍生的CD37抗原。
人源化抗体与猕猴CD37的结合亲和性
人源化抗体huCD37-38,huCD37-50,huCD37-51,huCD37-56和huCD37-57被测定它们与300-19/CD37mac细胞表达猕猴CD37的结合亲和性。使用二次FITC-缀合的山羊-抗-人抗体来进行流式细胞术结合测试,并且如实施例2中所述进行分析,对于各抗体通过非线性回归产生的剂量-响应曲线。各抗体的表观解离常数(Kd)的数值使用GraphPad Prism v4(GraphPad software,San Diego,CA)来计算。从图10B明显的是,数种分离的人源化抗体结合猕猴CD37,而huCD37-3不是这样。huCD37-38,huCD37-50,huCD37-51,huCD37-56和huCD37-57的Kd值分别对应于1.1nM,1.8nM,14nM,5nM和2nM。因此,人源化不会影响分离的抗体的结合特异性。
实施例9
嵌合和人源化抗体的促凋亡活性
在Ramos细胞上评价嵌合和人源化抗体的促凋亡活性。将细胞和10nM浓度的抗体或huIgG同种型对照抗体孵育20小时,然后膜联蛋白-V-FITC和TO-PRO-3染色,并且进行流式细胞术分析。ChCD37-12保留muCD37-12的强烈促凋亡活性。和4%的未处理的对照细胞相比,在使用muCD37-12或chCD37-12抗体处理后约40%的Ramos细胞是膜联蛋白-V阳性。类似地,和4%的同种型对照处理的或未处理的细胞相比,在使用huCD37-3,huCD37-38,huCD37-50,huCD37-51,huCD37-56或huCD37-57抗体处理后约40%的Ramos细胞是膜联蛋白-V阳性。相反,使用抗-CD20抗体利妥昔单抗处理导致只有13%的膜联蛋白-V阳性细胞。所述结果证实此处分离的鼠抗-CD37抗体的强烈促凋亡活性通过衍生自它们的嵌合或人源化抗体而得以保持。因此,该组抗-CD37抗体的独特的功能性能,在不存在交联的情况下强烈的促凋亡活性,不会受到嵌合或人源化的不利影响。
huCD37-3和TRU-016的促凋亡活性
比较huCD37-3针对Ramos和Raji淋巴瘤细胞的促凋亡活性与抗-CD37 SMIP TRU-016的情况。TRU-016描述为不具有促凋亡活性的化合物,除非交联有二次抗体。明显的是,示例性抗-CD37抗体huCD37-3和chCD37-38针对两种淋巴瘤细胞系具有更强的促凋亡活性。比较于3%的未处理的对照细胞,使用huCD37-3或chCD37-38处理导致40%或49%的膜联蛋白-V阳性Ramos细胞。利妥昔单抗处理导致只有15%的膜联蛋白-V阳性Ramos细胞。相反,TRU-016处理不会增加膜联蛋白-V阳性Ramos细胞的百分率。同样,比较于7%的未处理的对照细胞,使用huCD37-3或chCD37-38处理导致34%或30%的膜联蛋白-V阳性Raji细胞。利妥昔单抗处理导致只有19%的膜联蛋白-V阳性Raji细胞。相反,TRU-016处理不会增加膜联蛋白-V阳性Ramos细胞的百分率。
人源化抗体的促凋亡活性的剂量应答
变化量的各抗体和Ramos细胞孵育20小时,然后膜联蛋白-V-FITC和TO-PRO-3染色,并且进行流式细胞术分析。膜联蛋白-V阳性细胞的百分率针对半-log图中的抗体浓度绘制,使用非线性回归分析从曲线拟合来计算EC50值。明显的是,所有人源化抗体具有强烈促凋亡活性,膜联蛋白-V阳性细胞的最大百分率为至少40%。图11。用于该活性的EC50对应于0.08,0.08和0.11nM(分别为huCD37-3,huCD37-38和huCD37-50)。另外,用于该活性的EC50对应于0.41,0.57和1.01nM(分别为huCD37-51,huCD37-56和huCD37-57)。相反,比较于4%的使用同种型对照抗体处理的细胞,使用抗-CD20抗体利妥昔单抗处理导致膜联蛋白-V阳性细胞的最大百分率仅为15%。
实施例10
嵌合和人源化抗-CD37抗体的增殖测试
嵌合和人源化抗-CD37抗体抑制细胞生长的能力使用体外细胞毒性测试来测量,如实施例4所述。使用SU-DHL-4和DOHH-2淋巴瘤细胞的典型增殖测试的结果展现于图12。明显的是,所有抗体能够基本上和以剂量依赖性方式抑制SU-DHL-4细胞的增殖。例如,使用muCD37-3处理降低SU-DHL-4细胞的生存力为35%,EC50为0.07nM。类似地,在测试的最高抗体浓度下,使用chCD37-3,huCD37-3v1.0或huCD37-3v1.01处理降低SU-DHL-4细胞的生存力为约30%,EC50分别为0.03nM,0.06nM或0.03nM。同样,所有抗体能够基本上和以剂量依赖性方式抑制DOHH-2滤泡性淋巴瘤细胞的增殖。例如,使用muCD37-3处理降低DOHH-2细胞的生存力为45%,EC50为0.05nM。类似地,使用chCD37-3,huCD37-3v1.0或huCD37-3v1.01处理降低DOHH-2细胞的生存力为约35%,EC50分别为0.06nM,0.07nM或0.05nM。该结果证实各种版本的CD37-3抗体具有类似的抗-增殖活性,其不会受到嵌合或人源化的影响。
在类似的体外细胞毒性测定中测试另外的人源化抗-CD37抗体。所有测试的人源化抗体能够基本上和以剂量依赖性方式抑制SU-DHL-4细胞的增殖。例如,使用huCD37-38处理降低SU-DHL-4细胞的生存力为24%,EC50为0.42nM,,而使用huCD37-50处理降低SU-DHL-4细胞的生存力为31%,EC50为0.39nM。相反,使用抗-CD20抗体利妥昔单抗处理降低SU-DHL-4细胞的生存力为35%,EC50为1.6nM。另外,使用huCD37-51或huCD37-56处理降低SU-DHL-4细胞的生存力为24%,EC50分别为0.60nM或0.68nM。而且,使用huCD37-57处理降低SU-DHL-4细胞的生存力为31%,EC50为0.42nM。使用同种型对照抗体处理对于SU-DHL-4细胞的生存力没有影响。
比较于其他抗体的huCD37-3的抗-增殖活性
为了进一步表征分离的抗-CD37抗体的抗-增殖活性,我们比较了示例性huCD37-3抗体与抗-CD37 SMIP TRU-16化合物的效果。使用肿瘤微阵列的免疫组织化学证实CD37和CD20在NHL的亚型中表现出类似的表达图案和流行性。参见下表12。因此,还比较了抗-CD20抗体利妥昔单抗。细胞系组包括Granta-519,SU-DHL-4,Namalwa和Daudi淋巴瘤细胞。图13。
表12:比较于CD20染色,在淋巴瘤肿瘤微阵列上CD37染色
在所有情况下,huCD37-3处理导致细胞生存力以剂量依赖性方式降低。例如,使用huCD37-3处理降低Granta-519细胞的生存力为约37%,EC50为0.062nM。利妥昔单抗处理降低Granta-519细胞的生存力为约47%,EC50为0.36nM。使用huCD37-3处理降低SU-DHL-4细胞的生存力为约17%,EC50为0.053nM。利妥昔单抗处理降低SU-DHL-4细胞的生存力为约20%,EC50为0.2nM。截然不同的是,使用TRU-016处理不会在明显程度上或以剂量依赖性方式降低Granta-519或SU-DHL-4细胞的生存力。在进一步例子中,使用huCD37-3处理降低Namalwa细胞的生存力为约47%,EC50为0.1nM,并且降低Daudi细胞的生存力为约68%,EC50为0.25nM。利妥昔单抗处理对于Namalwa细胞没有影响,但是降低Daudi细胞的生存力为约69%,EC50为2.6nM。截然不同的是,使用TRU-016处理不会在明显程度上或以剂量依赖性方式降低Namalwa或Daudi细胞的生存力。最后,使用huCD37-3处理降低Ramos细胞的生存力为约53%,EC50为0.08nM,而TRU-016和利妥昔单抗处理都不会Ramos细胞生存力产生任何影响。该结果强调分离的抗-CD37抗体的抗-增殖活性的独特性。
实施例11
CD37抗体的CDC活性
为了评价嵌合和人源化抗-CD37抗体的补体依赖性细胞毒性(CDC)活性,根据公开的方法(Gazzano-Santoro H,J Immunol Methods.1997202(2):163-71)来进行细胞基测定。将抗体以50μL/孔等分三份到平底96-孔组织培养板中,其在RHBP(RPMI-1640,20mMHEPES,0.1%BSA,1%青霉素-链霉素)培养基中各种浓度下,典型地为5μg/mL(=3.3x 10- 8M)至2.3ng/mL(=1.5x 10-11M)。将靶细胞以5x 104细胞加入在100μL的RHBP培养基/孔的抗体。冻干人补体(Sigma-Aldrich,St.Louis,US)使用1mL无菌纯化的水/小瓶重组,并且在使用前立即稀释5倍至具有RHBP培养基的20%储液中。50μL/孔的补体溶液加入各孔中至最终浓度5%。将板在37℃下在5%CO2加湿孵育器中孵育2h,以允许补体介导的胞溶。在该孵育时间后,Alamar Blue试剂(Invitrogen)加入各孔至最终浓度为10%,以测量保留细胞的生存力。在EX540/EM590 nm处测量荧光度(相对荧光单位,RFU)之前,将板在37℃下孵育16至20小时。对照包括在具有培养基和补体但没有细胞(仅有培养基,0%生存力)与具有细胞和补体但没有抗体(仅有细胞,100%生存力)的三份孔中。各样品的特定细胞生存力的百分率通过下列来测定:%生存力=(样品–仅有培养基)/(仅有细胞–仅有培养基)。
使用Ramos细胞的示例性CDC测定的结果展现于图14。吃惊地,chCD37-12针对Ramos细胞具有有效的CDC活性。在测试的最高抗体浓度下,其降低Ramos细胞的生存力为32%,EC50为0.037μg/mL。另外,数种分离的抗体显示出在变化程度上具有针对Ramos的CDC活性。使用huCD37-3,huCD37-38,huCD37-50处理导致分别降低细胞生存力为59%,50%和45%。在测试的最高抗体浓度下,使用huCD37-51,huCD37-56或huCD37-56处理适度地将Ramos细胞的细胞生存力为约70-80%。
实施例12
CD37抗体的ADCC活性
使用新鲜分离的人自然杀伤(NK)细胞作为效应子细胞,乳酸脱氢酶(LDH)释放测试被用于测定肿瘤细胞系的抗体-依赖性细胞介导的细胞毒性(ADCC)(Shields RL,J BiolChem.2001 276(9):6591-604)。使用NK Isolation Kit II改进的方案(MiltenyiBiotech,130-091-152),NK细胞首先分离自正常供体的人血液(Research BloodComponents,Inc.,Brighton,MA)。将血液用1x PBS稀释2倍。将25mL的稀释的血液仔细地在50mL圆锥管中在25mL的Ficoll Paque上分层,并且以400g在RT下离心45min。周围血液单核细胞(PBMC)收集自界面,转移到新的圆锥50mL管中,并且使用1x PBS洗涤一次。将PBMC重悬浮在2mL的NK-分离缓冲液中(1x PBS,0.5%BSA,2mM EDTA),然后500μL的Biotin-抗体Cocktail加入细胞混悬液中。Biotin-抗体Cocktail含有生物素化的抗体,其结合淋巴细胞(除了NK细胞),从而导致NK细胞的阴性选择。将混合物在4℃下孵育10min,然后加入1.5mL的NK-分离缓冲液和1mL的抗-Biotin微珠。将细胞-抗体混合物在4℃下孵育另外15min。然后,将细胞使用50mL的NK-分离缓冲液洗涤一次,并重悬浮在3mL的NK-分离缓冲液中。然后,MACS LS柱安装在自动MACS分离器上(Miltenyi Biotech),并且使用3mL的NK-分离缓冲液预洗涤。将细胞混悬液自动地施加在柱上,洗涤,并且具有未标记的NK细胞的流出的部分收集到新的50-mL圆锥管中。将所得NK细胞平板接种到30mL的完全RPMI培养基中(RPMI-1640,补充5%胎牛血清,1%青霉素-链霉素,1mM HEPES,1mM丙酮酸钠,1%100X MEM非必需氨基酸溶液)过夜。在RHBP培养基(RPMI-1640培养基,补充20mM HEPES,pH 7.4,0.1%BSA和1%青霉素-链霉素)中进行随后的测定和所有稀释。
将在RHBP培养基中各种浓度的抗体以50μL/孔一式两份分到圆底96-孔板中。将靶细胞以106细胞/mL重悬浮在RHBP培养基中,并且以100μL/孔加至含有抗体稀释液的各孔中。含有靶细胞和抗体稀释液的板在37℃下孵育30min。然后将NK细胞以50μL/孔加至含有靶细胞的孔中。典型比例为1个靶细胞比3-4个NK细胞。建立下列对照用于各试验:单独NK细胞,单独靶细胞(自发LDH释放),靶细胞和NK细胞(抗体独立性LDH释放),靶细胞和10%Triton X-100(最大LDH释放)。将混合物在37℃下孵育4h以允许细胞胞溶。将板以1200rpm离心10min,并将100μL的上清仔细地转移到新的平底96-孔板中。来自细胞毒性检测试剂盒(Roche1 644 793)的LDH反应混合物(100μL/孔)加入各孔中,并在室温下孵育5至30min。在490nm(OD490)下测量样品的光学密度。各样品的特定胞溶百分率使用下列来确定:特定胞溶百分率=(样品值–自发释放)/(最大释放–自发释放)*100。
和人源化抗体一起孵育导致在存在人NK效应子细胞的情况下针对Daudi,Ramos和Granta-519淋巴瘤细胞的良好的ADCC活性。它们针对Daudi淋巴瘤细胞的ADCC活性和TRU-016的ADCC活性进行比较(图15)。
使用huCD37-3,huCD37-38或huCD37-50抗体处理导致约41%,39%或40%Daudi细胞胞溶,EC50值分别为0.42ng/mL,1.31ng/mL或2.42ng/mL。该活性类似于得自观察到的使用42%Daudi细胞胞溶的TRU-016处理,并且EC50值为0.93ng/mL。另外,使用huCD37-51,huCD37-56和huCD37-57处理导致约39%,36%或36%的Daudi细胞胞溶,EC50值分别为5.7ng/mL,4.3ng/mL或7.9ng/mL。
分离的抗体针对Ramos淋巴瘤细胞的ADCC活性和TRU-016的ADCC活性进行比较。使用huCD37-3,huCD37-38或huCD37-50抗体处理导致约43%,42%或46%Ramos细胞胞溶,EC50值分别为0.95ng/mL,2.0ng/mL或3.0ng/mL。该活性类似于得自观察到的使用59%Ramos细胞胞溶的TRU-016处理,并且EC50值为1.53ng/mL。另外,使用huCD37-51,huCD37-56和huCD37-57处理导致约53%,43%或44%的Ramos细胞胞溶,EC50值分别为5.7ng/mL,4.3ng/mL或7.9ng/mL。
在另外的试验中,huCD37-3和chCD37-38针对Granta-519细胞的ADCC活性和TRU-016的ADCC活性进行比较。使用huCD37-3或chCD37-38抗体处理导致约19%或18%Granta-519细胞胞溶,EC50值分别为0.13ng/mL或0.73ng/mL。TRU-016处理导致观察到的16%Granta-519细胞胞溶,EC50值为0.83ng/mL。

抗原表位映射
用于不同CD37抗体的抗原表位所要求的氨基酸的局域化可有助于建立通常或独特的功能特性与特定分子相互作用之间的联系。CD37的胞外域含有两个胞外环,小环为约18个残基,大环由约135个氨基酸构成。对于之前公开的CD37抗体,抗原表位要求并未描述。为了进一步表征本发明的分离的CD37抗体,我们构建了数种CD37抗原变体,其在较大胞外环中具有AA置换。
CD37变体克隆和表达
构建哺乳动物表达质粒,其含有全部人或猕猴CD37 cDNA序列,密码子由BlueHeron Biotechnologies优化和合成,并且侧翼有XbaI和BamHI限制性内切位点以促进克隆到pSRa载体多克隆位点。由于人和猕猴CD37序列高度同源(图16),因此这些构建体的表达能够从下列那些情况来区别人和猕猴交叉反应性抗体:识别抗原表位,其要求在这两个物种之间11个细胞外CD37氨基酸中至少一个不同,这如实施例8中所述。
为了进一步表征CD37抗体抗原表位,构建一系列鼠和人嵌合CD37构建体。由于小CD37胞外环的尺寸和高度同源性,抗原表位的局域化努力对大胞外环进行了限制。大胞外环的EcoRV至Pst1盒编码残基I108至Q235被重新设计以通过引入4个独特的限制性内切位点来进一步节段为5个部分,所述位点可在人、鼠和猕猴CD37序列之间是保守的(图17)。创建下列人和小鼠嵌合CD37构建体:

为了保存一个这样的限制性内切位点Kpn1,人R176包括在所有鼠/人嵌合构建体中。鼠和人CD37盒订购自Blue Heron,并且和由PCR产生的初始人CD37构建体的5'端片段一起克隆到pSRa载体中以引入EcoRV位点,并从初始猕猴CD37构建体中取出3’端Pst1至Xba1限制性片段。然后使用标准限制性内切酶消化和利用通常独特的限制性内切位点的连接来构建鼠和人嵌合CD37盒。
hCD37-M1变体通过下列方式来创建:插入EcoRV-SacII限制性片段,其编码类似鼠CD37序列的AA S109至A138。同样,hCD37-M3变体通过下列方式来创建:插入KpnI-Blp1限制性片段,其编码类似鼠CD37序列的AA V177至L201。hCD37-M45变体通过下列方式来创建:插入Blp1-PstI限制性片段,其编码类似鼠CD37序列的AA S202至I243。所得克隆通过限制性内切酶消化、然后进行DNA测序来证实。
稳定的细胞系通过下列方式获得:使用标准电穿孔方法,将鼠和人嵌合CD37变体表达质粒转染到300-19细胞中。简言之,使用在260V和960μF设定的BioRad Gene Pulser,5x 106 300-19细胞被电穿孔到冷RPMI-1640培养基中。随后,将细胞稀释,并且平板接种到96-孔板中的RPMI-1640培养基中,所述培养基补充10%FBS和50μMβ-疏基乙醇。在24小时后,以最终浓度2mg/mL加入G418(Invitrogen),以选择转染的细胞。在2周后,分离单一集落,并且通过流式细胞术和扩大来分析用于CD37表面表达。
结合CD37变体的抗体
各种CD37抗体与细胞表达人CD37野生型和变体的结合通过流式细胞术使用1.5μg/mL的各抗体来分析。本发明的分离的抗体和市售CD37抗体WR17以及TRU-016SMIP相比较。在图18A中可见,所有抗体结合野生型CD37表达细胞。同样,所有测试的抗体结合hCD37-M3变体(图18B)。相反,本发明的分离的抗体结合hCD37-M1变体,而TRU-016和WR17不能结合hCD37-M1变体(图19A)。CD37-50和CD37-51抗体与TRU-016也能够结合hCD37-M45变体。WR17显示部分结合hCD37-M45变体,而其他抗体CD37-3,CD37-12,CD37-38,CD37-56和CD37-57不能结合(图19B)。这暗示所有本发明的分离的抗体不需要在hCD37-M1变体中的12AA残基,其改变至相应鼠AA残基以结合CD37抗原。相反,CD37-3,CD37-12,CD37-38,CD37-56和CD37-57抗体要求hCD37-M45变体中10个AA残基中的至少一个,其改变至相应鼠AA残基以结合CD37抗原。
未预料的结果表明,本发明的分离的抗体表示新型种类的CD37抗体,其具有功能特性的独特联合。

抗-CD37抗体美登醇缀合物的体外细胞毒性的概述
将这些细胞毒性结果结合在一起,明显的是,由分离的抗-CD37抗体制备的缀合物显示出针对一组CD37-阳性淋巴瘤细胞系的特异性细胞毒性(图32B)。在各测试的情况下,对于各CD37-表达细胞系观察到良好特异性窗口,这表明细胞毒性是由于抗-CD37抗体特异性结合靶细胞。另外,huCD37-3-SMCC-DM1和非特异性缀合物显示出针对抗原-阴性Molt-4细胞的相同较差细胞毒性。这证实,对于该示例性缀合物观察到的细胞毒性取决于CD37表达。huCD37-3抗体针对多种细胞系也是活性的,包括DOHH-2,Granata-519,SU-DHL-4,JVM-2和JVM-3。相反,抗-CD37 SMIP TRU-016化合物对于这些细胞系中任一种的存活没有直接的影响。抗-CD20抗体在大部分这些细胞系中显示出比huCD37-3更不直接的活性,尽管经常通过定量流式细胞术测量更高的CD20的表达水平(图32A)。

效力
huCD37-3抗体和其PEG4-mal-DM1与SMCC-DM1缀合物在建立的异种移植物模型中使用皮下移植到SCID小鼠中的BJAB淋巴瘤细胞来测试。通过肿瘤体积将动物随机分到治疗组,此时肿瘤达到的平均肿瘤体积为约120mm3并且在细胞以10mg/kg的huCD37-3 Ab,huCD37-3-SMCC-DM1或huCD37-3-PEG4-mal-DM1接种后9天治疗一次。如图28中可见,使用缀合物的治疗导致平均肿瘤体积更明显的减小。如上所述使用各治疗组的平均肿瘤体积来计算对于各治疗的%T/C值。在细胞接种后24天的%T/C值对应于48%,16%或5%(分别为huCD37-3,huCD37-3-SMCC-DM1或huCD37-3-PEG4-mal-DM1)。在细胞接种后74天,huCD37-3-SMCC-DM1处理导致9个中1个无肿瘤存活者(TFS),而huCD37-PEG4-mal-DM1治疗导致9个中1个TFS。在huCD37-3抗体或PBS载体对照组中未观察到TFS。另外,huCD37-3-SMCC-DM1在以5mg/kg的单剂量在该模型中在细胞接种后24天的%T/C值为34%,这也是活性的。这表明,huCD37-3抗体的美登醇缀合物,例如SMCC-DM1或PEG4-mal-DM1缀合物,在BJAB模型中具有较高活性。
huCD37-3抗体,PEG4-mal-DM1和SMCC-DM1缀合物在SU-DHL-4异种移植物模型中的

3异种移植物模型中的体内效力
使用皮下移植到SCID小鼠中的JVM-3慢性淋巴细胞性白血病细胞,建立的异种移植物模型用于测试huCD37-3抗体和其huCD37-3-SMCC-DM1缀合物。通过肿瘤体积将动物随机分到治疗组,在接种后7天以单剂量10mg/kg的huCD37-3抗体,5或10mg/kg剂量的huCD37-3-SMCC-DM1缀合物,六剂量的5mg/kg的ofatumumab每周两次,三周;或使用单50mg/kg剂量的苯达莫司汀开始治疗。在图31中,不同治疗组的平均肿瘤体积针对肿瘤细胞接种后的时间进行绘制。使用huCD37-3抗体治疗导致平均肿瘤体积减小,而使用huCD37-3-SMCC-DM1缀合物治疗导致平均肿瘤体积更明显减小。如上所述使用各治疗组的平均肿瘤体积来计算对于各治疗的%T/C值。在细胞接种后20天的%T/C值对应于31%,19%,10%,35%和38%(分别为huCD37-3,5mg/kg huCD37-3-SMCC-DM1,10mg/kg huCD37-3-SMCC-DM1,ofatumumab和苯达莫司汀)。在研究结束时,在细胞接种后76天,huCD37和ofatumumab抗体治疗都导致10个中1个无肿瘤存活者(TFS),而5和10mg/kg的huCD37-3-SMCC-DM1分别导致10个中1个TFS和10个中2个TFS。在苯达莫司汀或PBS载体对照组中未观察到TFS。这表明,huCD37-3抗体本身使用10mg/kg剂量在JVM-3模型中是活性的。美登醇缀合物huCD37-3-SMCC-DM1和未缀合的抗体效力相比显示出增强的效力。另外,使用huCD37-3-SMCC-DM1美登醇缀合物治疗导致比ofatumumab或苯达莫司汀治疗在该模型中甚至更大的效力。
抗-CD37抗体缀合物的体内效力的概述
CD37仍未被评价为美登醇免疫缀合物的靶,然而CD20是这样的情况。CD37结构类似CD20,因为两种抗原都是细胞表面蛋白,其含有4个跨膜域以及一个小和一个大的胞外环。针对任一种抗原的抗体显示出缓慢内化,并且具有慢至中等速度的细胞内代谢(Presset al.1989,Cancer Res.49(17):4906-12,and Press et al.1994,Blood.83(5):1390-7)。CD20抗体的免疫缀合物之前被评价。在一个情况下,抗-CD20抗体的非可裂解MCC-DM1缀合物显示出和未缀合的抗体的相同的效力,而相同抗体的可裂解SPP-DM1缀合物显示出在SCID小鼠中的Granta-519异种移植物模型中改善的效力(Polson AG,Cancer Res 2009;69:2358-64)。类似地,由酸稳定酰胺接头制备的利妥昔单抗的卡奇霉素缀合物在裸小鼠中的Ramos异种移植物模型中不显示出改善的体内效力。只有由酸稳定二甲基酰肼Ac-But接头制备的利妥昔单抗的卡奇霉素缀合物在该研究中显示出改善的体内效力(DiJoseph JF,Cancer Immunol Immunotherapy 2007;56:1107-1117)。
截然不同的是,和未缀合的抗体相比,本发明的数种分离的抗-CD37抗体的非可裂解SMCC-DM1缀合物在BJAB,SU-DHL-4,DoHH2 and JVM-3异种移植物模型中显示出显著改善的体内效力。这暗示,分离的抗体具有独特的性能,其允许它们体内更有效地作为美登醇缀合物例如SMCC-DM1缀合物。
