本专利申请要求于2017年6月20日提交的美国临时专利申请62/522,516和于2017年9月1日提交的美国临时专利申请62/553,438的优先权。
技术领域
本公开提供了具有与CD38靶标结合的IgG抗体的抗体药物缀合物(ADC),所述IgG抗体在其铰链区中的Cys位点处缀合。本公开还提供了治疗多发性骨髓瘤的方法,所述方法包括提供有效量的CD38 ADC。
背景技术
CD38是一种45kD的II型跨膜糖蛋白,具有长的C端胞外域和短的N端胞质域。CD38蛋白是一种双功能外切酶,其可以催化NAD+转化为环状ADP-核糖(cADPR),也可以将cADPR水解为ADP-核糖。在个体发育过程中,CD38出现在CD34+定向干细胞和淋巴样、红系和髓样细胞的谱系定型祖细胞上。CD38的表达主要在淋巴谱系中持续存在,并且在T细胞和B细胞发育的不同阶段具有不同的表达水平。
CD38在许多造血系统恶性肿瘤中和源自各种造血系统恶性肿瘤的细胞系中上调,所述造血系统恶性肿瘤包括非霍奇金淋巴瘤(NHL)、伯基特淋巴瘤(BL)、多发性肿瘤(MM)、B慢性淋巴细胞性白血病(B-CLL)、B和T急性淋巴细胞白血病(ALL)、T细胞淋巴瘤(TCL)、急性骨髓性白血病(AML)、毛细胞白血病(HCL)、霍奇金淋巴瘤(HL)和慢性骨髓性白血病(CML)。另一方面,造血系统中大多数的原始多能干细胞是CD38-。CD38在造血系统恶性肿瘤中的表达及其与疾病进展的相关性使得CD38成为抗-CD38抗体疗法的引人注目的靶标。
据报道,CD38参与Ca2+的动员(Morra等人,1998,FASEB J.,12:581-592;Zilber等人,2000,Proc.Natl.Acad.Sci.USA,97:2840-2845),并参与淋巴和髓样细胞或细胞系中通过多种信号分子的酪氨酸磷酸化进行的信号转导,所述信号分子包括磷脂酶C-γ、ZAP-70、syk和c-cbl(Funaro等人,1993,Eur.J.Immunol.,23:2407-2411;Morra等人,1998,FASEBJ.,12:581-592;Funaro等人,1990,J Immunol,145:2390-2396;Zubiaur等人,1997,JImmunol,159:193-205;Deaglio等人,2003,Blood 102:2146-2155;Todisco等人,2000,Blood,95:535-542;Konopleva等人,1998,J.Immunol.,161:4702-4708;Zilber等人,2000,Proc.Natl.Acad.Sci.USA,97:2840-2845;Kitanaka等人,1997,J.Immunol.,159:184-192;Kitanaka等人,1999,J.Immunol.,162:1952-1958;Mallone等人,2001,Int.Immunol.,13:397-409)。CD38被指出是淋巴和髓样细胞在正常发育期间成熟和活化的重要信号分子。
CD38功能的证据来自于CD38-/-敲除小鼠,该小鼠具有先天免疫缺陷,并且由于树突状细胞迁移缺陷而具有降低的T细胞依赖性体液应答(Partida-Sanchez等人,2004,Immunity,20:279-291;Partida-Sanchez等人,2001,Nat.Med.,7:1209-1216)。然而,尚不清楚小鼠中CD38的功能是否与人类中的相同,因为造血过程中的CD38表达模式在人与小鼠之间存在很大差异:a)与人类中不成熟的祖干细胞不同,小鼠中类似的祖干细胞表达高水平的CD38(Randall等人,1996,Blood,87:4057-4067;Dagher等人,1998,Biol.BloodMarrow Transplant,4:69-74),b)在人B细胞发育过程中,发现了在生发中心B细胞和浆细胞中的高CD38表达水平(Uckun,1990,Blood,76:1908-1923;Kumagai等人,1995,J.Exp.Med.,181:1101-1110),而在小鼠中,相应细胞中的CD38表达水平低(Oliver等人,1997,J.Immunol.,158:108-1115;Ridderstad and Tarlinton 1998,J.Immunol.,160:4688-4695)。
在文献中已经描述了在各种肿瘤细胞和细胞系上的若干种具有不同增殖特性的抗人CD38抗体。例如,在存在来自MM患者或正常个体的外周血单核效应细胞(mononucleareffector cell)的情况下,具有小鼠Fab和人IgG1 Fc的嵌合OKT10抗体非常有效地介导针对淋巴细胞的抗体依赖性细胞介导的细胞毒性(ADCC)(Stevenson等人,1991,Blood,77:1071-1079)。已经显示,抗-CD38抗体AT13/5的CDR移植的人源化形式具有针对CD38阳性细胞系的有效ADCC活性。已经显示,人类单克隆抗-CD38抗体通过ADCC和/或补体依赖性细胞毒性(CDC)介导CD38阳性细胞系的体外杀灭,并延迟带有MM细胞系RPMI-8226的SCID小鼠中的肿瘤生长(WO2005/103083A2)。另一方面,若干抗-CD38抗体,IB4、SUN-4B7和OKT10,而非IB6、AT1或AT2,诱导来自正常个体的外周血单核细胞(PBMC)的增殖(Ausiello等人2000,Tissue Antigens,56:539-547)。
已经显示,一些现有技术中的抗体能够触发CD38+B细胞的凋亡。然而,这些抗体仅能在存在基质细胞或基质来源的细胞因子的情况下触发CD38+B细胞的凋亡。据报道,一种激动性抗-CD38抗体(IB4)防止人类生发中心(GC)B细胞凋亡(Zupo等人,1994,Eur.J.Immunol.,24:1218-1222),诱导KG-1和HL-60AML细胞增殖(Konopleva等人,1998,J.Immunol.,161:4702-4708),但诱导Jurkat T淋巴母细胞凋亡(Morra等人,1998,FASEBJ.,12:581-592)。另一抗-CD38抗体T16诱导来自ALL患者的未成熟淋巴样细胞和白血病淋巴母细胞的凋亡(Kumagai等人,1995,J.Exp.Med.,181:1101-1110),以及来自AML患者的白血病成髓细胞的凋亡(Todisco等人2000,Blood,95:535-542),但T16仅在存在基质细胞或基质来源的细胞因子(IL-7、IL-3、干细胞因子)的情况下诱导凋亡。
因此,发明人认为采用抗-CD38抗体进行靶向的抗体药物缀合物(ADC)带来了提供有效的抗肿瘤活性的希望和潜力,并同时具有减少副作用的优势。

ADC制备实施例1
ADC46的制备
将亲和纯化的抗-CD38抗体进行缓冲液交换至具有4mM EDTA的50mM磷酸钠缓冲液(pH 7.0-7.2),浓度为5-10mg/mL。向该抗体储备液的一部分中加入新制的10mM的三(2-羧乙基)膦(TCEP)水溶液,直至20倍摩尔过量。将所得混合物在4-8℃下孵育过夜。通过凝胶过滤色谱法或若干轮的离心过滤除去过量的TCEP。对回收的经还原的抗体材料进行UV-Vis定量分析,随后确认足够的游离巯基/抗体比。简言之,将新制的在50mM磷酸钠,pH 7.0-7.2,4mM EDTA中的(5,5’-二硫代双-(2-硝基苯甲酸)的1mM等分试样与等体积的纯化抗体溶液混合。在412nm下测量所得吸光度,并使用14,150M-1cm-1的消光系数确定减少的半胱氨酸含量。
为引发化合物52与抗-CD38抗体的缀合,首先将L014-077溶解于3:2的乙腈/水混合物中,浓度为5mM。然后将该新制的毒性物质-连接子溶液的等分试样以4.5-5倍摩尔过量加入到一部分经还原、纯化的抗-CD38抗体中间体中。充分混合并在环境温度下孵育≥1小时后,通过HIC-HPLC色谱分析粗缀合反应,在280nm波长检测下确认反应完成(起始抗体峰消失)。随后使用配有PBS平衡的Superdex 200pg柱(GE Healthcare)的AKTA系统,通过凝胶过滤色谱法进行ADC46的纯化。基于UV-VIS和HIC-HPLC计算药物/抗体比(DAR)。图8显示了起始抗-CD38抗体和纯化的ADC46的代表性的HIC-HPLC比较。使用分析型SEC-HPLC来确定所得ADC46为低百分数(<5%)高分子量(HMW)聚集体。

采用与产生ADC46的步骤相同的方式进行ADC41的抗-CD38抗体的还原和分析。为引发最终的药物-连接子与抗体的缀合,首先将化合物22溶解于2:3的乙腈/水混合物中,浓度为5mM。随后将丙二醇(PG)加入经还原、纯化的抗-CD38抗体的等分试样中,以得到10-30%(v/v)PG终浓度,随后以4.5-5倍摩尔过量加入新制的化合物22溶液。随后采用与ADC46中的步骤相同的方式进行ADC41的分析和纯化。图9显示了起始抗-CD38抗体和纯化的ADC41的代表的性HIC-HPLC比较。
测试实施例1
收到动物后,将其以每只笼子5只小鼠饲养在环境受控的房间里。随意给动物提供啮齿动物食物和水。在开始细胞施用和给药之前至少72小时,使小鼠适应实验室条件。在适应期间,确定动物的健康状况。仅使用在研究开始前被观察为健康的动物。
该实施例提供了体内实验,比较了对小鼠使用对照(PBS)、抗-CD38 IgG1抗体(STI-0602和STI-0607)和两种抗体的ADC变体的治疗。该程序首先进行肿瘤细胞接种和肿瘤建立:
a.用10%FBS U87培养基(EMEM)培养U87细胞,并用0.05%胰蛋白酶收获。将细胞用无血清EMEM洗涤2次,计数,以5x106细胞/0.2mL或25x106细胞/mL的浓度重悬于无血清EMEM和基质胶的1:1混合物中,并皮下注射至每只小鼠的右上腹。
b.接种后第6-9天开始,使用数字卡尺测量肿瘤体积尺寸以监测肿瘤的生长,此后每周两次,直到研究终止。
c.用数字卡尺测量肿瘤。测量长度(最长尺寸)和宽度(与长度垂直并在同一平面内的距离)。用于计算肿瘤体积的公式为TV(mm3)=1/2x L x W2。
治疗:
a.一旦肿瘤被分期至所需的体积(平均200至300mm3),则将动物随机分组,并剔除具有很大或很小肿瘤的小鼠。按肿瘤体积随机将小鼠分成8组,每组10只。
b.根据图4,用媒介物或测试物品治疗小鼠。小鼠共接受5剂。
c.监测肿瘤反应,一旦建立了明确的治疗趋势和/或当媒介物治疗的小鼠中的肿瘤负荷达到IACUC协议限值(2000mm3),则终止研究。
测试实施例2
本实施例是在小鼠体内比较两种公开的CD38 ADC的体内实验。在体内研究中,将1000万Daudi-fluc细胞静脉内注射入NOD-SCID小鼠中。小鼠肿瘤形成后4天,静脉(IV)注射抗-CD38抗体和ADC至小鼠。通过肿瘤的发光强度变化来监测抗体或ADC对肿瘤生长的抑制(图3、4、5和6)。
测试了ADC#45和ADC#41。两种ADC使用相同的A2抗体。Daudi和Ramos细胞系获自ATCC。在含10%FBS的RPMI 1640 1X培养基中,在37℃和5%二氧化碳湿润的环境中培养细胞。将细胞培养2周时间,并在收获前传代3次。注射前,将Daudi或Ramos细胞重悬于1:1比例的HBSS(汉克平衡盐溶液)和Matrigel中,将1000万个细胞/0.2ml皮下注射至每只小鼠的右上腹中。
在含10%FBS和0.2ug/ml嘌呤霉素的RPMI 1640 1X培养基中,在37℃和5%二氧化碳湿润的环境中培养Daudi-luc细胞。将细胞培养2周时间,并在收获前传代3次。注射前,将Daudi-luc细胞重悬于HBSS中。将1000万个细胞/0.2ml静脉内注射至每只小鼠的尾静脉中。
将6周龄的雌性NOD SCID小鼠(Charles River)用于Daudi皮下异种移植和Daudi-luc静脉异种移植。在研究中,将6周龄的雌性Nu/Nu小鼠(Charles River)用于Ramos皮下异种移植。接收后,将小鼠以每只笼子5只小鼠饲养在环境受控的房间里。随意提供啮齿动物食物和水。在开始给药之前,使小鼠适应实验室条件72小时。在适应期间,监测动物的健康状况。通过组号和研究号标识每个笼子,通过耳标分别标识小鼠。
下表显示了研究设计和给药方案。
接种后第5-7天开始,通过使用数字卡尺测量肿瘤的宽度和长度来监测肿瘤的生长,此后每周两次,直到肿瘤体积达到~100-250mm3。使用以下公式计算肿瘤体积:体积(mm3)=[长度(mm)x宽度(mm)2]/2。
一旦肿瘤被分期到所需的体积,则将动物随机分组,并剔除具有很大或很小肿瘤的小鼠。将小鼠分组,每组的动物数量如研究设计中所示。然后用PBS、Ab、ADC#45或ADC#41静脉治疗小鼠(0.2ml/动物)。治疗后,监测肿瘤生长、动物健康和体重。当该组的平均皮下肿瘤负荷超过2000mm3、动物体重减轻超过20%或研究结束时,处死测试动物。
在整个实验期间,每周测量肿瘤体积两次。使用以下公式计算TGI(肿瘤生长抑制%):TGI=[(PBS组的上次体积尺寸–PBS对照的同一天的治疗组的体积)/(PBS组的上次体积尺寸)]x 100。通过电平衡每周测量每只小鼠的体重两次。
计算个体的体重和肿瘤体积的原始数据。计算组的平均值和标准差,并进行统计分析(采用单向ANOVA和Dunnett多重比较检验;GraphPad Prism 6.0)。将所有治疗组与PBS组进行比较。P<0.05被认为具有统计学意义。
与PBS治疗对照组相比,10mg/kg的ADC#45显著抑制Daudi肿瘤生长。尽管3周后肿瘤恢复生长,但单次10mg/kg治疗显著延迟了肿瘤生长。在这种情况下,可以测试多次治疗以实现持续的肿瘤抑制。而3mg/kg或1mg/kg的单剂量的ADC#45并未明显抑制肿瘤的生长。然而,尽管差异并不显著,但与PBS治疗对照组相比,单剂量的ADC#45确实显示出对肿瘤生长的轻微抑制。在这项研究中观察到剂量反应,其中较高剂量显示出更好的肿瘤生长抑制(图1A)。用10mg/kg或更低剂量的单剂量静脉内施用ADC#45的测试动物没有体重减轻(图1B)。
同样,与PBS治疗对照组相比,10mg/kg的ADC#45显著抑制Ramos肿瘤的生长,并具有长达60天的持续肿瘤抑制作用。3mg/kg或1mg/kg的单剂量的ADC#45未显著抑制肿瘤生长。然而,尽管差异并不显著,但与PBS治疗对照组相比,3mg/kg或1mg/kg的单剂量的ADC#45确实显示出对肿瘤生长的轻微抑制。在这项研究中观察到剂量反应,其中较高剂量显示出更好的肿瘤生长抑制(图2A)。用10mg/kg或更低剂量的单剂量静脉内施用ADC#45的测试动物没有体重减轻(图2B)。
3mg/kg的单剂量的ADC#45完全抑制肿瘤生长,且直至治疗后第48天,存活率为100%。与PBS对照组相比,3mg/kg的单剂量的ADC#41显著抑制肿瘤生长,并显著延长小鼠的存活期(图3和4)。
10mg/kg单剂量的ADC#45和ADC#41显著抑制肿瘤生长,而在3mg/kg或1mg/kg剂量下,两者在Daudi和Ramos皮下注射异种移植肿瘤小鼠模型中均未显示出显著的肿瘤抑制。在雌性NOD SCID小鼠的Daudi-luc静脉注射肿瘤模型中,3mg/kg单剂量的ADC#45完全抑制肿瘤生长,且直至48天,存活率为100%。在雌性NOD SCID小鼠的Daudi-luc静脉注射肿瘤模型中,3mg/kg单剂量的ADC#41显著抑制肿瘤生长,并延长生存期。在本研究中观察到ADC#45和ADC#41的剂量反应。在相同(10mg/kg或3mg/kg)剂量方案下,相比于ADC#41,ADC#45显示出更好的肿瘤生长抑制作用。在研究期间,所有治疗组均未观察到与治疗相关的体重减轻。
