Abstract
本發明涉及配體-細胞毒性藥物偶聯物、其製備方法及其應用。具體而言,本發明提供了一種通式為PC-L-Dr的配體-細胞毒性藥物偶聯物,其製備方法以及該配體-細胞毒性藥物偶聯物及含有其的藥物組成物藉由受體調節在製備治療癌症的藥物中的用途,其中通式(PC-L-Dr)中的各取代基與說明書中的定義相同。
Description
本發明涉及一類全新結構的配體-細胞毒性藥物偶聯物。具體地說,本發明涉及抗體-細胞毒性藥物偶聯物,也涉及本發明偶聯物的製備方法、包含所述偶聯物的藥物組成物以及所述偶聯物或藥物組成物的用途。
化療依然是包括手術、放射線治療、以及靶向治療法在內的最重要的抗癌手段之一。盡管高效細胞毒素的種類很多,但是腫瘤細胞和正常細胞之間差别很小,限制了這些抗腫瘤化合物由於毒副作用在臨床上的廣泛應用。而抗腫瘤單株抗體對於腫瘤細胞表面抗原的特異性,抗體藥物已成為抗腫瘤治療的前線藥物,但單獨使用抗體作為抗腫瘤藥物時,療效經常不盡人意。
抗體藥物偶聯物(antibody drug conjugate,ADC)把單株抗體或者抗體片段藉由穩定的化學接頭化合物與具有生物活性的細胞毒素相連,充分利用了抗體對正常細胞和腫瘤細胞表面抗原結合的特異性和細胞毒素的高效性,同時
又避免了前者療效偏低和後者毒副作用過大等缺陷。這也就意味着,與以往傳統的化療藥物相比,抗體藥物偶聯物能精準地結合腫瘤細胞並降低將對正常細胞的影響。
早期的ADC藥物主要使用鼠源的單株抗體,因為人類的免疫反應造成一部分藥物難以到達標靶。其次,早期使用的包括阿黴素(doxorubicin)在內的效應分子的生物活性較低,限制了第一代抗體藥物偶聯物的療效。除此之外,抗體的來源、接頭連接的方式和數目也未得到優化。
2013年2月,Kadcyla®(ado-trastuzumab emtansine,T-DM1)獲得美國FDA批准,用於治療HER2陽性同時對曲妥珠單株抗體(Trastuzumab,商品名:Herceptin®和紫杉醇有抗藥性的晚期或轉移性乳腺癌患者。Mylotarg®和Adcetris®都是針對血液腫瘤進行靶向治療,和固體腫瘤相比組織結構相對簡單。Kadcyla®是美國FDA批准的治療固體腫瘤的第一個ADC藥物。
Kadcyla®採用ImmunoGen的技術將高活性的有絲分裂抑制劑DM1用一個穩定的硫醚健接頭連到羅氏公司的曲妥珠單株抗體上,平均一個曲妥珠單株抗體結合大約3.5個DM1,曲妥珠單株抗體在病人體內特異性結合乳腺癌細胞,經細胞內吞後在細胞內斷裂釋放出DM1,DM1在細胞內的聚集濃度足以導致細胞因有絲分裂障礙而死亡,腫瘤病灶隨之消退。T-DM1既保留了Herceptin®的抗體依賴性的細胞增殖抑制作用,同時又增加了潛在的細胞毒素藥物的效應。而且因為其毒素靶向在腫瘤細胞內釋放,藥物毒
副作用並沒有隨著療效的增加而同步增大。
帕妥珠單株抗體(Pertuzumab,也稱作2C4,商品名Perjeta)是一種重組人源化單株抗體,它是第一個被稱作“HER二聚化抑制劑”的單株抗體。藉由結合HER2阻滯了HER2與其他HER受體的二聚化作用。帕妥珠單株抗體已經證實在HER2高表現及低表現的前列腺癌等模型上均有抑制腫瘤生長的作用。
與曲妥珠單株抗體(Trastuzumab,商品名Herceptin)結合位點位於HER2胞外區的近膜區IV亞域上抑制下游信號路徑不同,帕妥珠單株抗體則是藉由結合在II域(二聚化域)有效抑制HER2的異源二聚化反應。因此,曲妥珠單株抗體只能對HER2過度表現的癌症患者尤其是乳腺癌患者有一定療效,而帕妥珠單株抗體雖然和曲妥珠單株抗體作用同一靶點,且二者有同樣的內吞特點,但因其作用機制不同,在抑制二聚化後可以切斷由ErbB家族受體介導的信號路徑,可能会有比單獨阻斷HER2信號路徑更廣泛的應用範圍。
目前ADC藥物的偶聯技術主要有兩種:T-DM1採用的是將細胞毒性藥物與抗體的自由胺基隨機偶聯;而Adcetris®採用的是將細胞毒性藥物和抗體鉸鏈區還原後的自由巰基偶聯。兩種偶聯方法都產出了載藥量數不一致的混合物。如T-DM1雖然平均載藥量是3.5,但載藥量的分布可從0~8。過低的載藥量影響了ADC的藥效,而過高的載藥量則更容易因對抗體的過分修飾而導致ADC藥物
經組織的巨噬細胞體系識別並破壞。這不僅減低了ADC的半衰期也因為毒素在非靶點組織的累積而增加毒性副作用;而Adcetris®用還原劑將抗體鉸鏈區的二硫鍵進行還原,對抗體本身的穩定性產生一定影響。相關的ADC藥物專利有WO2007008603、WO2013173393、WO2005081711、WO2013173391、WO2013173392、WO2013173393和WO2012010287。本發明提供一種有新型連接方式,新的毒素與抗體組合,從而有更有益效果的新的ADC化合物。

“Fv片段”包含輕鏈或/和重鏈的可變區VH功能區。
“Fc區”相當於IgG的CH2和CH3功能區,無抗原結合活性,是抗體分子與效應分子和細胞相互作用的部位。
“鉸鏈區”用於連接抗體的Fab段和Fc段。在本發明中可以將雙特異性融合蛋白與Fc段連接。
本發明所述的抗體較佳係針對靶細胞上細胞表面抗原的特異性抗體,非限制性實施例為以下抗體:曲妥珠單株抗體,是用於治療乳腺癌的人源化抗HER2抗體,適用於治療HER2過度表現的轉移性乳腺癌。帕妥珠單株抗體
(Pertuzumab,也稱作2C4,商品名Perjeta),是一種重組人源化單株抗體。它是第一個稱作“HER二聚化抑制劑”的單株抗體,藉由結合HER2阻滯了HER2與其他HER受體的二聚化作用,從而減緩了腫瘤的生長。帕妥珠單株抗體已經證實在HER2高表現及低表現的前列腺癌等模型上均有抑制腫瘤生長的作用。帕妥珠單株抗體已經美國FDA批準用於治療HER2陽性的轉移性乳腺癌。尼妥珠單株抗體(Nimotuzumab,商品名泰欣生),是一個以表皮生長因子受體(EGFR)為靶點的單株抗體藥物,可用於治療惡性腫瘤的人源化單株抗體。EGFR在多種實體瘤中過度表現,如頭頸癌、肺癌、結直腸癌中,都存在EGFR過度表現現象。
術語“細胞毒性藥物”是指在腫瘤細胞內具有較強破壞其正常生長的化學分子。細胞毒性藥物原則上在足夠高的濃度下都可以殺死腫瘤細胞,但是由於缺乏特異性,在殺傷腫瘤細胞的同時,也會導致正常細胞的凋亡,導致嚴重的副作用。在本發明的實施方式中,細胞毒性藥物表示為D/D1。
術語“載藥量”是指式(I)分子中每個配體上載入的細胞毒性藥物平均數量,也可以表示為藥物量和抗體量的比值,藥物載量的範圍可以是每個配體(Pc)連接1-8個細胞毒性藥物(D),在本發明的實施方式中,載藥量表示為y,可用常規方法如UV/可見光光譜法,質譜,ELISA試驗和HPLC特徵鑒定偶聯反應後每個ADC分子的藥物品均數量。
在本發明中,y可能受連接位點數量的限制。本發明的一個實施方式中,細胞毒性藥物藉由連接單元偶聯在配體的N端胺基和/或離胺酸殘基的ε-胺基上,一般地,偶聯反應中能與抗體偶聯的藥物分子數將小於理論上的最大值。
可以用以下非限制性方法控制配體細胞毒性藥物偶聯物的載量,包括:(1)控制連接試劑和單株抗體的莫耳比,(2)控制反應時間和溫度,(3)選擇不同的反應試劑。
常規的藥物組成物的製備見中國藥典。
術語“載體”用於本發明的藥物,是指能改變藥物進入人體的方式和在體內的分佈、控制藥物的釋放速度並將藥物輸送到靶向器官的體系。藥物載體釋放和靶向系統能夠減少藥物降解及損失,降低副作用,提高生物利用度。如可作為載體的高分子表面活性劑由於其獨特的兩親性結
構,可以進行自組裝,形成各種形式的聚集體,較佳的實例如膠束、微乳液、凝膠、液晶、囊泡等。這些聚集體具有包載藥物分子的能力,同時又對膜有良好的滲透性,可以作為優良的藥物載體。
術語“賦形劑”是在藥物製劑中除主藥以外的附加物,也可稱為輔料。如片劑中的黏合劑、填充劑、崩解劑、潤滑劑;半固體製劑軟膏劑、霜劑中的基質部分;液體製劑中的防腐劑、抗氧劑、矯味劑、芳香劑、助溶劑、乳化劑、增溶劑、滲透壓調節劑、著色劑等均可稱為賦形劑。
術語“稀釋劑”又稱填充劑,其主要用途是增加片劑的重量和體積。稀釋劑的加入不僅保證一定的體積大小,而且減少主要成分的劑量偏差,改善藥物的壓縮成型性等。當片劑的藥物含有油性組分時,需加入吸收劑吸收油性物,使保持“乾燥”狀態,以利於製成片劑。如澱粉、乳糖、鈣的無機鹽、微晶纖維素等。
藥物組成物可以是無菌注射水溶液形式。可在使用的可接受的溶媒和溶劑中有水、林格氏液和等滲氯化鈉溶液。無菌注射製劑可以是其中活性成分溶於油相的無菌注射水包油微乳。例如將活性成分溶於大豆油和卵磷脂的混合物中。然後將油溶液加入水和甘油的混合物中處理形成微乳。可藉由局部大量注射,將注射液或微乳注入患者的血流中。或者,最好按可保持本發明化合物恆定循環濃度的方式給予溶液和微乳。為保持這種恆定濃度,可使用連續靜脈內遞藥裝置。這種裝置的實例是Deltec CADD-PLUS.
TM.5400型靜脈注射泵。
藥物組成物可以是用於肌內和皮下給藥的無菌注射水或油懸浮液的形式。可按已知技術,用上述那些適宜的分散劑或濕潤劑和懸浮劑配製該懸浮液。無菌注射製劑也可以是在無毒腸胃外可接受的稀釋劑或溶劑中製備的無菌注射溶液或懸浮液,例如1,3-丁二醇中製備的溶液。此外,可方便地用無菌固定油作為溶劑或懸浮介質。為此目的,可使用包括合成甘油單或二酯在內的任何調和固定油。此外,脂肪酸例如油酸也可以製備注射劑。
術語“還原劑”是在氧化還原反應裏,失去電子或有電子偏離的物質。還原劑本身在廣義上說也是抗氧化劑,具有還原性,經氧化,其產物叫氧化產物。在本發明的實施方式中,還原劑表示為RA,還原劑的非限制性實例包括:H2、碳(C)、一氧化碳(CO)、還原鐵粉(Fe)、鋅粉(Zn)、鹼金屬(常用的有Li、Na、K)、其他活潑金屬(如Mg、Al、Ca、La等)、氯化亞錫(SnCl2)、草酸、硼氫化鉀(KBH4)、硼氫化鈉(NaBH4)、氰基硼氫化鈉(NaCNBH3)、三乙醯氧基硼氫化鈉((CH3COO)3BHNa)、氫化鋁鋰(LiAlH4)、次磷酸、次磷酸鈉、硫代硫酸鈉(Na2S2O3),本發明較佳的還原劑為氰基硼氫化鈉或三乙醯氧基硼氫化鈉。
術語“巰基保護基”指當同時含有巰基和其他基團的化學分子參與反應的情況下,為使反應只發生在特定的基團處,而避免巰基遭受影響,將巰基加以保護,當反應完成後脫除的基團,在本發明的實施方式中,巰基保護基表
示為T,巰基保護基的非限制性實例包括:-第三丁基、-乙醯基、-正丙醯基、-異丙醯基、-三苯基甲基、-甲氧基甲基、-2-(三甲矽烷基)乙氧甲基,本發明較佳的巰基保護基為乙醯基。

2、細胞鋪板。將HepG2單細胞懸浮液混勻,用細胞培養液調整活細胞密度至6×104cells/ml,將密度調整過後的細胞懸浮液混勻,以100μl/孔加入96孔細胞培養板。將培養板置於37℃,5% CO2恆溫培養箱內培養18-20小時。
3、化合物準備
用DMSO(二甲基亞碸,上海泰坦科技股份有限公司)
溶解化合物,配製成初始濃度為10mM的存儲液。
加入10μl 10mM的化合物樣品至U型底96孔板(樣品板1)第一列各孔。,在第一列各化合物樣品孔內加入90μl DMSO,即對原液稀釋10倍,作為起始濃度點,接下来進行3倍梯度稀釋,每種化合物稀釋10個濃度點。稀釋液為DMSO溶液。第12列加入60μl 100% DMSO。第11列加入20μl 1mM的陽性藥物參考品。
取一新的U型底96孔板(樣品板2),用完全培養基對樣品板1內的各孔樣品進行20倍稀釋。接着再取一新的U型底96孔板(樣品板3),將樣品板2內的各孔樣品進行最终的10倍稀釋。
4、加樣操作。細胞预培養完成後,取出96孔細胞培養板,棄上清液。以100μl/孔,將96孔樣品板3中的各樣品稀釋液依次加入到96孔細胞培養板內。各化合物樣品每種濃度點作2復孔檢測。加樣操作不應超過30min。完成加樣操作後,將96孔細胞培養板置於37℃,5% CO2二氧化碳恆溫培養箱中培養76小時左右。
5、顯色操作。取出96孔細胞培養板,向各孔中以10μl/孔加入CCK-8顯色液。輕輕拍板混勻10次以上,將細胞培養板置於37℃,5%CO2二氧化碳恆溫培養箱繼續培養2.0小時。
6、讀板操作。取出96孔細胞培養板,置於酶標儀(PerkinElmer,VICTOR 3)中,用酶標儀測定在450nm處的吸光度。
按照以上步驟,測試本發明藥物化合物對A549腫瘤細胞體外增殖的抑制活性。細胞培養液同樣為DMEM/F12培養基。

本發明典型化合物顯著抑制HER2高表現胃癌NCI-N87裸小鼠皮下移植瘤的生長,並且荷瘤小鼠對以上藥物均能較好耐受。
測試例5:EGFRV3抗體及包含其的ADC對HCC827移植瘤裸小鼠療效測試
一、試驗目的
本實驗以Nude-nude裸小鼠為受試動物,評價本發明ADC化合物39、40多劑量腹腔注射給藥後,對人非小細胞肺癌HCC827移植瘤裸小鼠的療效。
本次實驗結果顯示,發明ADC化合物39、40多劑腹腔注射給藥一次後觀察抑瘤效果,並給藥後第38天時結束
實驗,ADC化合物39(0.05mg/mouse)的抑瘤率為62.78%,與空白組相比差異有統計學意義(p<0.05);ADC化合物40(0.025mg/mouse)的抑瘤率為49.20%,與空白組相比差異不顯著;ADC化合物40(0.05mg/mouse)的抑瘤率為86.8%,與空白組相比有顯著差異(p<0.01);ADC化合物40(0.1mg/mouse)的抑瘤率為93.41%;與空白組相比差異有統計學意義(p<0.05)
二、受試藥物及材料
1、受試藥物
本發明ADC化合物:ADC化合物39,ADC化合物40,
2、配製方法:均用PBS稀釋配製。
3、試驗動物
Nude-nude裸小鼠,SPF,16-20g,♀,購自上海西普爾.必凱實驗動物有限責任公司。合格證號:SCXK(滬)2008-0016。
三、試驗方法
裸小鼠實驗室環境適應三天後,進行腫瘤細胞移植。在裸小鼠右肋部皮下接種HCC827細胞(4×106+50% matrigel/mouse),接種後第21天,腫瘤長至209.41±25.93mm3(d1)開始給藥。給藥劑量及方法具體見表5。
每週測定2次移植瘤體積,稱量裸小鼠體重並記錄資料。
使用Excel統計軟體:平均值以avg計算;SD值以STDEV計算;SEM值以STDEV/SQRT計算;組間差異P值
以TTEST計算。
腫瘤體積(V)計算公式為:V=1/2×L長×L短2
相對體積(RTV)=VT/V0
抑瘤率(%)=(CRTV-TRTV)/CRTV(%)
其中V0、VT分別為實驗開始時及實驗結束時的腫瘤體積。CRTV、TRTV分別為實驗結束時的空白對照組(Blank)及實驗組的相對腫瘤體積。
四、試驗結果
本次實驗結果顯示抑瘤效果至第38天,ADC化合物39(0.05mg/mouse)的抑瘤率為62.78%,與空白組相比差異有統計學意義(p<0.05);ADC化合物40(0.025mg/mouse)的抑瘤率為49.20%,與空白組相比差異無統計學意義(p>0.05);ADC化合物40(0.05mg/mouse)的抑瘤率為86.8%,ADC化合物40(0.1mg/mouse)的抑瘤率為93.41%,與空白組相比均有顯著差異(p<0.01);此外,ADC化合物40三個不同劑量組的抑瘤效果具劑量依賴關係。
