Abstract
揭示一種抗葉酸受體α (FOLR1)重鏈抗體(例如,UniAbs™),以及製備此類抗體之方法;包含此類抗體之組合物,包括醫藥組合物;以及其用於治療以葉酸受體α (FOLR1)表現為特徵之病症的用途。
Description
本發明係關於結合於葉酸受體α (FOLR1)之人類重鏈抗體(例如UniAbs™)。本發明進一步關於製備此類抗體之方法;包含此類抗體之組合物,包括醫藥組合物;以及其用於治療以FOLR1表現為特徵之病症的用途。
葉酸受體α (FOLR1)
FOLR1,亦稱FRα (UniProt P15328;HGNC ID 3791),係一種糖基磷脂醯肌醇(GPI)連接之膜蛋白,其結合於葉酸及還原之葉酸衍生物且介導5-甲基四氫葉酸之細胞內遞送。FOLR1具有在中性pH值下對葉酸具有高親和力的210個胺基酸之細胞外域(ECD)。內化後,酸性pH值會導致FOLR1發生構形變化,此變化降低FOLR1對葉酸之親和力,從而介導葉酸之釋放,隨後FOLR1再循環至細胞表面。Wibowo AS等人,
Proc Natl Acad Sci USA. 2013年9月17日;110(38):15180-8。FOLR1在許多實體腫瘤類型中過度表現,包括卵巢、乳房、肺、腎、結腸直腸及腦,但FOLR1在諸如腎、肺、視網膜及腦之正常健康組織中的表現僅限於上皮之頂面,從而減少其暴露於循環中之FOLR1靶向劑且使FOLR1成為有吸引力之治療標靶。Cheung A等人
Oncotarget. 2016年8月9日;7(32):52553-52574。FOLR1亦可能與FOLR1陽性腫瘤之成像及診斷有關,且此外,據報導,在卵巢癌患者中可溶性FOLR1升高。Kurosaki A等人
Int J Cancer. 2016年4月15日;138(8):1994-2002。已描述若干種對FOLR1具有特異性之單株抗體、抗體-藥物結合物(ADC)及葉酸藥物結合物。Cheung A等人
Oncotarget. 2016年8月9日;7(32):52553-52574。此外,正在研究抗FOLR1嵌合抗原受體(CAR) T細胞治療卵巢癌。Kershaw MH等人

重鏈抗體
在習知IgG抗體中,重鏈與輕鏈之締合部分係由於輕鏈恆定區與重鏈CH1恆定域之間的疏水性相互作用。重鏈構架2 (FR2)及構架4 (FR4)區中存在額外殘基,該等殘基亦有助於重鏈與輕鏈之間的此種疏水性相互作用。
然而,已知駱駝科動物(包括駱駝、單峰駱駝及美洲駝之駱駝(Tylopoda)亞目)之血清含有僅由成對H鏈組成之主要類型抗體(僅重鏈抗體或UniAbs™)。駱駝科(
Camelidae) (單峰駝(
Camelus dromedarius)、雙峰駝(
Camelus bactrianus)、大羊駝(
Lama glama)、原駝(
Lama guanaco)、羊駝(
Lama alpaca)及小羊駝(
Lama vicugna))之UniAbs™具有由單個可變域(VHH)、鉸鏈區及兩個恆定域(CH2及CH3)組成之獨特結構,該兩個恆定域與經典抗體之CH2及CH3域高度同源。此等UniAbs™缺少恆定區(CH1)之第一個結構域,該結構域在基因體中存在,但在mRNA加工過程中剪除。CH1域之缺乏可解釋UniAbs™中輕鏈之缺乏,因為此結構域係輕鏈恆定域之錨定位置。此類UniAbs™經自然進化,藉由來自習知抗體或其片段之三個CDR賦予抗原結合特異性及高親和力(Muyldermans, 2001;
J Biotechnol74:277-302;Revets等人, 2005;
Expert Opin Biol Ther5:111-124)。諸如鯊魚之軟骨魚類亦進化出一種獨特類型之免疫球蛋白,稱為IgNAR,其缺乏多肽輕鏈且完全由重鏈組成。IgNAR分子可藉由分子工程改造進行操縱以產生單重鏈多肽之可變域(vNAR) (Nuttall等人
Eur. J. Biochem. 270, 3543-3554 (2003);Nuttall等人
Function and Bioinformatics55, 187-197 (2004);Dooley等人,
Molecular Immunology40, 25-33 (2003))。
在1960年代已確定無輕鏈之僅重鏈抗體結合抗原之能力(Jaton等人(1968)
Biochemistry, 7, 4185-4195)。相對於四聚體抗體,以物理方式與輕鏈分離之重鏈免疫球蛋白保留80%之抗原結合活性。Sitia等人(1990)
Cell, 60, 781-790證明在哺乳動物細胞培養物中自重排小鼠μ基因移除CH1域可產生無輕鏈之僅重鏈之抗體。所產生之抗體保留VH結合特異性及效應功能。
經由免疫接種可產生針對多種抗原之具有高特異性及親和力之重鏈抗體(van der Linden, R. H., 等人
Biochim. Biophys. Acta. 1431, 37-46 (1999))且VHH部分很容易在酵母中純系及表現(Frenken, L. G. J., 等人
J. Biotechnol. 78, 11-21 (2000))。其表現水準、溶解度及穩定性顯著高於經典F(ab)或Fv片段之水準(Ghahroudi, M. A.等人
FEBS Lett. 414, 521-526 (1997))。

I. 定義
「包含」意謂雖然在組合物/方法/套組中需要所敘述之要素,但在申請專利範圍之範疇內可包括其他要素以形成組合物/方法/套組等。
「基本上由……組成」意謂將所描述之組合物或方法之範疇限制於不實質上影響本發明之基本及新穎特徵之指定材料或步驟。
「由……組成」意謂自組合物、方法或套組中排除未在申請專利範圍中指定之任何要素、步驟或成分。
本文中之抗體殘基係根據Kabat編號系統及EU編號系統編號。當提及可變域中之殘基(大約為重鏈之1-113殘基)時通常使用Kabat編號系統(例如,Kabat等人, Sequences of Immunological Interest. 第5版 Public Health Service, National Institutes of Health, Bethesda, Md. (1991))。當提及免疫球蛋白重鏈恆定區中之殘基時,通常使用「EU編號系統」或「EU索引」(例如,上述Kabat等人中報導之EU索引)。「如Kabat中之EU索引」係指人類IgG1 EU抗體之殘基編號。除非本文另外說明,否則提及抗體可變域中之殘基編號意謂藉由Kabat編號系統編號之殘基編號。除非本文另外說明,否則提及抗體恆定域中之殘基編號意謂藉由EU編號系統編號之殘基編號。
抗體,亦稱免疫球蛋白,通常包含至少一條重鏈及一條輕鏈,其中重鏈及輕鏈之胺基端結構域在序列上係可變的,因此通常稱為可變區結構域,或重(VH)或輕(VL)鏈可變域。該兩個結構域通常締合形成特異性結合區,不過如此處將論述,特異性結合亦可藉由僅重鏈之可變序列獲得,且抗體之多種非天然組態為所屬領域中已知及使用。
「功能性」或「生物活性」抗體或抗原結合分子(包括僅重鏈抗體及多特異性(例如,雙特異性)三鏈抗體樣分子(TCA,本文所述)係一種能夠在結構、調節、生物化學或生物物理事件中發揮其一或多種天然活性之抗體或抗原結合分子。例如,功能性抗體或例如TCA之其他結合分子可具有特異性結合抗原之能力,且該結合可繼而引發或改變細胞或分子事件,諸如信號轉導或酶活性。功能性抗體或例如TCA之其他結合分子亦可阻斷受體之配位體活化或充當促效劑或拮抗劑。抗體或例如TCA之其他結合分子發揮其一或多種天然活性之能力取決於若干因素,包括多肽鏈之正確折疊及組裝。
本文中之術語「抗體」在最廣泛之意義上使用,且具體涵蓋單株抗體、多株抗體、單體、二聚體、多聚體、多特異性抗體(例如雙特異性抗體)、僅重鏈抗體、三鏈抗體、TCA、單鏈Fv (scFv)、奈米抗體等,且亦包括抗體片段,只要該等片段表現出所需之生物活性即可(Miller等人(2003) Jour. of Immunology 170:4854-4861)。抗體可為鼠類、人類、人類化、嵌合的,或源自其他物種。
術語抗體可指全長重鏈、全長輕鏈、完整免疫球蛋白分子;或任何此等多肽之免疫活性部分,亦即包含免疫特異性結合所關注之標靶或其部分之抗原的抗原結合位點之多肽,此類標靶包括但不限於產生與自體免疫性疾病相關之自體免疫抗體的癌細胞。本文揭示之免疫球蛋白可為免疫球蛋白分子之任何類型(例如,IgG、IgE、IgM、IgD及IgA)、類別(例如,IgG1、IgG2、IgG3、IgG4、IgA1及IgA2)或亞類,包括具有改變之Fc部分從而提供降低或增強之效應細胞活性的經工程改造之亞類。主題抗體之輕鏈可為κ輕鏈(Vκ)或λ輕鏈(Vλ)。免疫球蛋白可源自任何物種。在一個態樣中,免疫球蛋白主要來源於人類。
如本文所用,術語「單株抗體」係指自實質上同質之抗體群體中獲得之抗體,亦即,除了可能少量存在之可能天然存在之突變之外,構成該群體之個別抗體皆相同。單株抗體具有高度特異性,針對單個抗原位點。此外,與通常包括針對不同決定子(抗原決定基)之不同抗體之習知(多株)抗體製劑相比,每種單株抗體針對抗原上之單個決定子。根據本發明之單株抗體可藉由Kohler等人(1975)
Nature256:495首先描述之融合瘤方法製備,且亦可經由例如重組蛋白產生方法(參見例如美國專利第4,816,567號)製備。
與抗體相關之術語「可變」係指如下事實:抗體可變域之某些部分在抗體之間在序列上有很大差異,且用於每種特定抗體對其特定抗原之結合及特異性。然而,可變性並非均勻分佈在整個抗體可變域中。其集中在輕鏈及重鏈可變域中稱為高變區之三個區段中。可變域之較高保守部分稱為構架區(FR)。天然重鏈及輕鏈之可變域各包含四個FR,主要採用β-折疊組態,由三個高變區連接,形成環連接,且在一些情況下形成β-折疊結構之一部分。每條鏈中之高變區藉由FR緊密結合在一起,且與來自另一條鏈之高變區一起形成抗體之抗原結合位點(參見Kabat等人
, Sequences of Proteins of Immunological Interest, 第5版 Public Health Service, National Institutes of Health, Bethesda, MD. (1991))。恆定域不直接參與抗體與抗原之結合,但表現出各種效應功能,例如抗體參與抗體依賴性細胞毒性(ADCC)。
術語「高變區」在本文中使用時係指抗體之負責抗原結合之胺基酸殘基。高變區通常包含來自「互補決定區」或「CDR」之胺基酸殘基(例如,重鏈可變域中之殘基31-35 (H1)、50-65 (H2)及95-102 (H3);Kabat等人,
Sequences of Proteins of Immunological Interest, 第5版 Public Health Service, National Institutes of Health, Bethesda, MD. (1991))及/或來自重鏈可變域中之「高變環」殘基26-32 (H1)、53-55 (H2)及96-101 (H3)之彼等殘基;Chothia及Lesk
J. Mol. Biol.196:901-917 (1987))。在一些實施例中,「CDR」意謂如以下中定義之抗體之互補決定區:Lefranc, MP等人, IMGT, the international ImMunoGeneTics database, Nucleic Acids Res., 27:209-212 (1999)。「構架區」或「FR」殘基為除如本文定義之高變區/CDR殘基之外的彼等可變域殘基。
在本文中展示示例性CDR名稱,然而所屬領域之技術人員將理解,通常使用多種CDR定義,包括Kabat定義(參見「Zhao等人A germline knowledge based computational approach for determining antibody complementarity determining regions.」
Mol Immunol. 2010;47:694-700),其基於序列可變性,且係最常用的。Chothia定義係基於結構環區域之位置(Chothia等人「Conformations of immunoglobulin hypervariable regions.」
Nature. 1989; 342:877-883)。所關注之替代CDR定義包括但不限於以下揭示之彼等定義:Honegger, 「Yet another numbering scheme for immunoglobulin variable domains: an automatic modeling and analysis tool」
J Mol Biol. 2001;309:657-670;Ofran等人「Automated identification of complementarity determining regions (CDRs) reveals peculiar characteristics of CDRs and B-cell epitopes.」
J Immunol.2008;181:6230-6235;Almagro 「Identification of differences in the specificity-determining residues of antibodies that recognize antigens of different size: implications for the rational design of antibody repertoires」.
J Mol Recognit. 2004;17:132-143;及Padlan等人「Identification of specificity-determining residues in antibodies.」 Faseb J. 1995;9:133-139,其中每一者皆以引用之方式特定併入本文中。
術語「僅重鏈抗體」及「重鏈抗體」在本文中可互換使用,且在最廣泛意義上,係指缺乏習知抗體之輕鏈的抗體或抗體之更多或更多部分,例如抗體之一或多個臂。該等術語具體包括但不限於包含VH抗原結合域以及CH2及CH3恆定域但不存在CH1域之同源二聚抗體;此類抗體之功能性(抗原結合)變異體、可溶性VH變異體、包含一個可變域(V-NAR)及五個C樣恆定域(C-NAR)之同源二聚體之Ig-NAR及其功能片段;及可溶性單域抗體(sUniDabs™)。在一個實施例中,僅重鏈抗體由可變區抗原結合域構成,該可變區抗原結合域由構架1、CDR1、構架2、CDR2、構架3、CDR3 及構架4構成。在另一個實施例中,僅重鏈抗體由抗原結合域、鉸鏈區之至少一部分以及CH2及CH3域構成。在另一個實施例中,僅重鏈抗體由抗原結合域、鉸鏈區之至少一部分及CH2域構成。在另一個實施例中,僅重鏈抗體由抗原結合域、鉸鏈區之至少一部分及CH3域構成。本文中亦包括CH2及/或CH3域截短之僅重鏈抗體。在另一個實施例中,重鏈由抗原結合域及至少一個CH (CH1、CH2、CH3或CH4)域構成,但無鉸鏈區。僅重鏈抗體可呈二聚體形式,其中兩條重鏈藉由二硫鍵鍵結或以其他方式共價或非共價地彼此附接。僅重鏈抗體可屬於IgG亞類,但本文中亦包括屬於其他亞類,諸如IgM、IgA、IgD及IgE亞類之抗體。在一個具體實施例中,重鏈抗體屬於IgG1、IgG2、IgG3或IgG4亞型,特別是IgG1或IgG4亞型。在一個實施例中,重鏈抗體屬於IgG4亞型,其中一或多個CH域經修飾以改變抗體之效應功能。在一個實施例中,重鏈抗體屬於IgG1或IgG4亞型,其中一或多個CH域經修飾以改變抗體之效應功能。本文進一步描述改變效應功能之CH域修飾。重鏈抗體之非限制性實例描述於例如WO2018/039180中,其揭示內容以引用之方式整體併入本文中。
在一些實施例中,本文中之僅重鏈抗體用作嵌合抗原受體(CAR)之結合(靶向)域。該定義具體包括由人類免疫球蛋白轉殖基因大鼠產生之僅人類重鏈抗體(UniRat™),稱為UniAbs™。UniAbs™之可變區(VH)稱為UniDabs™,且為多功能構建區塊,其可與Fc區或血清白蛋白連接,用於研發具有多特異性、效力增加及半衰期延長之新穎療法。由於同源二聚體UniAbs™缺少輕鏈,因此缺少VL域,所以抗原由一個單一結構域,亦即重鏈抗體之重鏈可變域(VH或VHH)識別。
如本文所用,「完整抗體鏈」係包含全長可變區及全長恆定區(Fc)之鏈。完整「習知」抗體包含完整輕鏈及完整重鏈,以及用於分泌IgG之輕鏈恆定域(CL)及重鏈恆定域、CH1、鉸鏈、CH2及CH3。其他同型,諸如IgM或IgA,可具有不同CH域。恆定域可為天然序列恆定域(例如,人類天然序列恆定域)或其胺基酸序列變異體。完整抗體可具有一或多種「效應功能」,效應功能係指可歸因於抗體之Fc恆定區(天然序列Fc區或胺基酸序列變異Fc區)之彼等生物活性。抗體效應功能之實例包括C1q結合;補體依賴性細胞毒性;Fc受體結合;抗體依賴性細胞介導之細胞毒性(ADCC);吞噬作用;及細胞表面受體之下調。恆定區變異體包括改變效應子概況、與Fc受體之結合及其類似方面之彼等變異體。
根據重鏈之Fc (恆定域)之胺基酸序列,抗體及各種抗原結合蛋白可作為不同類別提供。重鏈Fc區有五個主要類別:IgA、IgD、IgE、IgG及IgM,且其中一些可進一步分為「亞類」(同型),例如IgG1、IgG2、IgG3、IgG4、IgA及IgA2。對應於不同類別抗體之Fc恆定域可分別稱為α、δ、ε、γ及μ。不同類別免疫球蛋白之次單元結構及三維組態係熟知的。Ig形式包括鉸鏈修飾或無鉸鏈形式(Roux等人(1998) J. Immunol. 161:4083-4090;Lund等人(2000) Eur. J. Biochem. 267:7246-7256;US 2005/0048572;US 2004/0229310)。基於恆定域之胺基酸序列,來自任何脊椎動物物種之抗體的輕鏈可分配為兩種類型之一,稱為κ (κ)及λ (λ)。根據本發明之實施例之抗體可包含κ輕鏈序列或λ輕鏈序列。
「功能性Fc區」具有天然序列Fc區之「效應功能」。效應功能之非限制性實例包括C1q結合;CDC;Fc受體結合;ADCC;ADCP;細胞表面受體(例如B細胞受體)之下調等。此類效應功能通常需要Fc區與受體相互作用,例如FcγRI、FcγRIIA、FcγRIIB1、FcγRIIB2、FcγRIIIA、FcγRIIIB受體,以及低親和力FcRn受體;且可使用所屬領域已知之各種分析法進行評估。「死」或「沉默」Fc為一種已突變以保留關於例如延長血清半衰期之活性,但不活化高親和力Fc受體,或對Fc受體之親和力降低的Fc。
「天然序列Fc區」包含與自然界中發現之Fc區之胺基酸序列一致的胺基酸序列。天然序列人類Fc區包括例如天然序列人類IgG1 Fc區(非A及A同種異型);天然序列人類IgG2 Fc區;天然序列人類IgG3 Fc區;及天然序列人類IgG4 Fc區,以及其天然存在之變異體。
「變異Fc區」包含由於至少一個胺基酸修飾,較佳一或多個胺基酸取代而不同於天然序列Fc區之胺基酸序列的胺基酸序列。較佳地,與天然序列Fc區或與親本多肽之Fc區相比,變異Fc區具有至少一個胺基酸取代,例如約一個至約十個胺基酸取代,且較佳約一個至約五個在天然序列Fc區或親本多肽Fc區中之胺基酸取代。本文之變異Fc區將較佳與天然序列Fc區及/或與親本多肽之Fc區具有至少約80%之同源性,且最佳至少約90%之同源性,更佳至少約95%之同源性。
變異Fc序列可在CH2區中EU索引位置234、235及237處包括三個胺基酸取代以減少之FcγRI結合(參見Duncan等人, (1988) Nature 332:563)。EU索引位置330及331處補體C1q結合位點中之兩個胺基酸取代減少補體固定(參見Tao等人, J. Exp. Med. 178:661 (1993)及Canfield及Morrison, J. Exp. Med. 173:1483 (1991))。位置233-236處人類IgG1或IgG2殘基及位置327、330及331處IgG4殘基之取代極大地降低ADCC及CDC (參見例如Armour KL.等人, 1999 Eur J Immunol. 29(8):2613-24;及Shields RL.等人, 2001. J Biol Chem. 276(9):6591-604)。人類IgG4 Fc胺基酸序列(UniProtKB No. P01861)在本文中提供為SEQ ID NO: 92。例如在以下中描述沉默IgG1:Boesch, A.W.等人, 「Highly parallel characterization of IgG Fc binding interactions.」 MAbs, 2014. 6(4): 第915-27頁,其揭示內容以引用之方式整體併入本文中。
其他Fc變異體亦為可能的,包括但不限於其中能夠形成二硫鍵之區域缺失,或其中天然Fc之N端的某些胺基酸殘基消除,或其中添加甲硫胺酸殘基之變異體。因此,在一些實施例中,抗體之一或多個Fc部分可在鉸鏈區包含一或多個突變以消除二硫鍵。在另一個實施例中,可完全移除Fc之鉸鏈區。在另一個實施例中,抗體可包含Fc變異體。
此外,可構築Fc變異體以藉由取代(突變)、缺失或添加胺基酸殘基以實現補體結合或Fc受體結合來移除或顯著降低效應功能。例如且不限於,缺失可發生在補體結合位點,例如C1q結合位點。在國際專利公開案第WO 97/34631號及第WO 96/32478號中揭示製備免疫球蛋白Fc片段之此類序列衍生物之技術。此外,Fc域可藉由磷酸化、硫酸化、醯化、糖基化、甲基化、法呢基化、乙醯化、醯胺化及其類似方式來修飾。
在一些實施例中,抗體包括包含T366W突變之變異人類IgG4 CH3域序列,其在本文中可視情況稱為IgG4 CH3杵序列。在一些實施例中,抗體包括包含T366S突變、L368A突變及Y407V突變之變異人類IgG4 CH3域序列,其在本文中可視情況稱為IgG4 CH3臼序列。可以任何合適之方式利用本文所述之IgG4 CH3突變,以便在抗體二聚體中之第一單體之第一重鏈恆定區上置放「杵」,且在抗體二聚體中之第二單體之第二重鏈恆定區上置放「臼」,從而促進抗體中所需之重鏈多肽次單元對之正確配對(異二聚化)。
在一些實施例中,抗體包含如下重鏈多肽次單元,該重鏈多肽次單元包括包含S228P突變、F234A突變、L235A突變及T366W突變之變異人類IgG4 Fc區(杵)。在一些實施例中,抗體包含如下重鏈多肽次單元,該重鏈多肽次單元包括包含S228P突變、F234A突變、L235A突變、T366S突變、L368A突變及Y407V突變之變異人類IgG4 Fc區(杵)。
術語「包含Fc區之抗體」係指包含Fc區之抗體。Fc區之C端離胺酸(根據EU編號系統之殘基447)可例如在抗體純化期間或藉由編碼抗體之核酸之重組工程改造而移除。因此,根據本發明之具有Fc區之抗體可包含具有或不具有K447之抗體。
本發明之態樣包括包含呈單價或二價組態之僅重鏈可變區的抗體。如本文所用,在提及僅重鏈可變區結構域時使用之術語「單價組態」意謂僅存在一個僅重鏈可變區結構域,具有單個結合位點(參見圖3之圖D,抗體之左臂)。相比之下,在提及僅重鏈可變區結構域時使用之術語「二價組態」意謂存在兩個僅重鏈可變區結構域(各具有單個結合位點),且藉由連接子序列連接(參見圖5之圖D,抗體之左臂)。連接子序列之非限制性實例在本文中進一步論述,且包括但不限於各種長度之GS連接子序列。當僅重鏈可變區呈二價組態時,兩個僅重鏈可變區結構域中之各者可對相同抗原或不同抗原(例如,對同一蛋白質上之不同抗原決定基;對兩種不同蛋白質等)具有結合親和力。然而,除非另外特別說明,否則表示為「二價組態」之僅重鏈可變區應理解為含有藉由連接子序列連接之兩個一致的僅重鏈可變區結構域,其中兩個一致的僅重鏈可變區中之各者對相同標靶抗原具有結合親和力。
本發明之態樣包括具有多特異性組態之抗體,該等組態包括但不限於雙特異性、三特異性等。已知多種方法及蛋白質組態且用於雙特異性單株抗體(BsMAB)、三特異性抗體等中。
已藉由重組融合兩種或更多種抗體之可變域開發多種產生多價人工抗體之方法。在一些實施例中,多肽上之第一及第二抗原結合域藉由多肽連接子連接。此類多肽連接子之一個非限制性實例為GS連接子,其具有四個甘胺酸殘基後接一個絲胺酸殘基之胺基酸序列,且其中該序列重複n次,其中n為在1至約10範圍內之整數,諸如2、3、4、5、6、7、8或9。此類連接子之非限制性實例包括GGGGS (SEQ ID NO: 81) (n=1)及GGGGSGGGGS (SEQ ID NO: 82) (n=2)。亦可使用其他合適之連接子,且描述於例如Chen等人, Adv Drug Deliv Rev. 2013年10月15日; 65(10): 1357-69,其揭示內容以引用之方式整體併入本文中。
術語「三鏈抗體樣分子」或「TCA」在本文中用於指包含三個多肽次單元、基本上由其組成或由其組成之抗體樣分子,其中兩個多肽次單元包含單株抗體之一條重鏈及一條輕鏈或包含抗原結合區及至少一個CH域的此類抗體鏈之功能性抗原結合片段、基本上由其組成或由其組成。此重鏈/輕鏈對對第一抗原具有結合特異性。第三多肽次單元包含以下、基本上由以下組成或由以下組成:僅重鏈抗體,其包括包含CH2及/或CH3及/或CH4域之Fc部分,缺乏CH1域;及一或多個抗原結合域(例如,兩個抗原結合域),其結合第二抗原之抗原決定基或第一抗原之不同抗原決定基,其中此類結合域源自抗體重鏈或輕鏈之可變區或與抗體重鏈或輕鏈之可變區具有序列一致性。此類可變區之部分可由V

L基因區段、D及J
H基因區段或J
L基因區段編碼。可變區可由重排V

TCA結合化合物利用「僅重鏈抗體」或「重鏈抗體」或「重鏈多肽」,如本文所用,該等術語意謂包含重鏈恆定區CH2及/或CH3及/或CH4但無CH1域之單鏈抗體。在一個實施例中,重鏈抗體由抗原結合域、鉸鏈區之至少一部分以及CH2及CH3域構成。在另一個實施例中,重鏈抗體由抗原結合域、鉸鏈區之至少一部分及CH2域構成。在另一個實施例中,重鏈抗體由抗原結合域、鉸鏈區之至少一部分及CH3域構成。本文中亦包括CH2及/或CH3域截短之重鏈抗體。在另一個實施例中,重鏈由抗原結合域及至少一個CH (CH1、CH2、CH3或CH4)域構成,但無鉸鏈區。僅重鏈抗體可呈二聚體形式,其中兩條重鏈藉由二硫鍵鍵結或以其他方式共價或非共價地彼此附接,且可視情況在一或多個CH域之間包括不對稱介面以促進多肽鏈之間的正確配對。重鏈抗體可屬於IgG亞類,但本文中亦包括屬於其他亞類,諸如IgM、IgA、IgD及IgE亞類之抗體。在一特定實施例中,重鏈抗體屬於IgG1、IgG2、IgG3或IgG4亞型,特別是IgG1亞型或IgG4亞型。TCA結合化合物之非限制性實例描述於例如WO2017/223111及WO2018/052503中,其揭示內容以引用之方式整體併入本文中。
重鏈抗體佔駱駝科動物,例如駱駝及美洲駝產生之IgG抗體之約四分之一(Hamers-Casterman C.等人, Nature. 363, 446-448 (1993))。此等抗體由兩條重鏈形成,但缺乏輕鏈。因此,可變抗原結合部分稱為VHH域,且其代表最小的天然存在之完整抗原結合位點,長度僅約120個胺基酸(Desmyter, A.等人, J. Biol. Chem. 276, 26285-26290 (2001))。經由免疫接種可產生針對多種抗原之具有高特異性及親和力之重鏈抗體(van der Linden, R. H.等人, Biochim. Biophys. Acta. 1431, 37-46 (1999))且VHH部分很容易在酵母中純系及表現(Frenken, L. G. J.等人, J. Biotechnol. 78, 11-21 (2000))。其表現水準、溶解度及穩定性顯著高於經典F(ab)或Fv片段之水準(Ghahroudi, M. A.等人FEBS Lett. 414, 521-526 (1997))。鯊魚亦顯示在抗體中具有單個VH樣域,稱為VNAR。(Nuttall等人Eur. J. Biochem. 270, 3543-3554 (2003);Nuttall等人Function and Bioinformatics 55, 187-197 (2004);Dooley等人, Molecular Immunology 40, 25-33 (2003))。

抗 FOLR1 抗體之製備
本發明之抗體可藉由所屬領域已知之方法製備。在一較佳實施例中,本文中之抗體由內源性免疫球蛋白基因經剔除或失活之轉殖基因動物產生,包括轉殖基因小鼠及大鼠,較佳大鼠。在一較佳實施例中,本文中之重鏈抗體在UniRat™中產生。UniRat™之內源性免疫球蛋白基因沉默,且使用人類免疫球蛋白重鏈轉殖基因座(translocus)來表現多樣化的自然優化之全人類HCAb譜系。雖然可使用多種技術剔除大鼠中之內源性免疫球蛋白基因座或使之沉默,但在UniRat™中,鋅指(內切)核酸酶(ZNF)技術用於使內源性大鼠重鏈J基因座、輕鏈Cκ基因座及輕鏈Cλ基因座不活化。用於顯微注射至卵母細胞中之ZNF構築體可產生IgH及IgL剔除(KO)株系。詳情參見例如Geurts等人, 2009, Science 325:433。Menoret等人, 2010, Eur. J. Immunol. 40:2932-2941報導Ig重鏈剔除大鼠之表徵。ZNF技術之優點在於,非同源末端接合亦可為同源整合提供標靶位點,其經由高達數kb之缺失使基因或基因座沉默(Cui等人, 2011, Nat Biotechnol 29:64-67)。UniRat™中產生之人類重鏈抗體稱為UniAbs™,且可結合習知抗體無法攻擊之抗原決定基。其高特異性、親和力及小尺寸使其成為單特異性及多特異性應用之理想選擇。
除UniAbs™之外,本文中特別包括缺乏駱駝科動物VHH構架及突變之僅重鏈抗體及其功能性VH區。此類僅重鏈抗體可例如在包含完整人類僅重鏈基因座之轉殖基因大鼠或小鼠中產生,如例如WO2006/008548中所述,但亦可使用其他轉殖基因哺乳動物,諸如兔、豚鼠、大鼠,較佳為大鼠及小鼠。僅重鏈抗體,包括其VHH或VH功能片段,亦可藉由重組DNA技術,藉由在合適真核或原核宿主,包括例如哺乳動物細胞(例如,CHO細胞)、大腸桿菌或酵母中表現編碼核酸來產生。
僅重鏈抗體之結構域組合抗體及小分子藥物之優點:可為單價或多價;毒性低;且製造成本低。由於其體積小,所以此等結構域易於投與,包括口服或局部投與,特徵為穩定性高,包括胃腸道穩定性;且其半衰期可根據所需之用途或適應症進行調整。此外,HCAb之VH及VHH域可以具有成本效益之方式製造。
在一特定實施例中,本發明之重鏈抗體,包括UniAbs™,在FR4區之第一個位置(根據Kabat編號系統之胺基酸位置101)處之天然胺基酸殘基殘基經另一胺基酸取代,該另一胺基酸能夠破壞在該位置處包含天然胺基酸殘基或與天然胺基酸殘基相關之表面暴露之疏水性區塊。此類疏水性區塊通常埋在與抗體輕鏈恆定區之介面中,但在HCAb中表面暴露,且至少部分係由於HCAb之不需要之聚集及輕鏈締合。取代之胺基酸殘基較佳帶電,且更佳帶正電,諸如離胺酸(Lys,K)、精胺酸(Arg,R)或組胺酸(His,H),較佳為精胺酸(R)。在一較佳實施例中,源自轉殖基因動物之僅重鏈抗體在位置101處含有Trp至Arg突變。所得HCAb較佳在生理條件下在缺乏聚集下具有高抗原結合親和力及溶解度。
作為本發明之一部分,在ELISA蛋白及細胞結合分析中鑑定具有來自UniRat™動物之獨特序列的與人類FOLR1結合之人類IgG抗FOLR1重鏈抗體(UniAb™)。所鑑定之重鏈可變區(VH)序列對於人類FOLR1蛋白結合及/或與FOLR1+細胞之結合呈陽性,且對於與不表現FOLR1之細胞之結合均呈陰性。參見例如表14。
與FOLR1蛋白上之非重疊抗原決定基結合之重鏈抗體,例如UniAbs™可藉由競爭性結合分析法,諸如酶聯免疫分析(ELISA分析)或流動式細胞測量術競爭性結合分析法來鑑定。例如,可利用與標靶抗原結合之已知抗體與所關注抗體之間的競爭。藉由使用此方法,可將一組抗體分為與參考抗體競爭之抗體及不與參考抗體競爭之抗體。非競爭性抗體經鑑定為結合不同抗原決定基,該抗原決定基不與參考抗體結合之抗原決定基重疊。通常,一種抗體固定,抗原與之結合,且在ELISA分析中測試第二標記(例如生物素化)之抗體結合所捕捉之抗原的能力。此亦可藉由使用表面電漿子共振(SPR)平臺來執行,該等平臺包括ProteOn XPR36 (BioRad公司)、Biacore 2000及Biacore T200 (GE Healthcare Life Sciences)以及MX96 SPR成像器(Ibis technologies公司),以及生物層干涉法平臺,諸如Octet Red384及Octet HTX (ForteBio, Pall公司)。有關更多細節,參見本文中之實例。
通常,如藉由標準技術,例如藉由上述競爭結合分析法所測定,若抗體導致參考抗體與標靶抗原之結合降低約15-100%,則其與參考抗體「競爭」。在各種實施例中,相對抑制為至少約15%、至少約20%、至少約25%、至少約30%、至少約35%、至少約40%、至少約45%、至少約50%、至少約55%、至少約60%、至少約65%、至少約70%、至少約75%、至少約80%、至少約85%、至少約90%、至少約95%或更高。

在一個實施例中,醫藥組合物包含結合於FOLR1之重鏈抗體(例如UniAb™)。在另一個實施例中,醫藥組合物包含對FOLR1蛋白上之兩個或更多個非重疊抗原決定基具有結合特異性之多特異性(包括雙特異性)重鏈抗體(例如UniAb™)。在一較佳實施例中,醫藥組合物包含對FOLR1具有結合特異性且對效應細胞上之結合標靶(例如,T細胞上之結合標靶,例如T細胞上之CD3蛋白)具有結合特異性的多特異性(包括雙特異性及TCA)重鏈抗體(例如UniAb™)。
根據本發明使用之抗體之醫藥組合物藉由將具有所需純度之蛋白質與視情況選用之醫藥學上可接受之載劑、賦形劑或穩定劑混合來製備(參見例如Remington's Pharmaceutical Sciences 第16版, Osol, A.編輯(1980)),諸如凍乾調配物或水溶液之形式用於儲存。可接受之載劑、賦形劑或穩定劑在所採用之劑量及濃度下對接受者無毒,且包括緩衝劑,諸如磷酸鹽、檸檬酸鹽及其他有機酸;抗氧化劑,包括抗壞血酸及甲硫胺酸;防腐劑(諸如十八烷基二甲基苄基氯化銨;氯化六甲銨;苯紮氯銨(benzalkonium chloride)、苄索氯銨(benzethonium chloride);苯酚、丁醇或苯甲醇;對羥基苯甲酸烷基酯,諸如對羥基苯甲酸甲酯或丙酯;鄰苯二酚;間苯二酚;環己醇;3-戊醇;及間甲酚);低分子量(少於約10個殘基)多肽;蛋白質,諸如血清白蛋白、明膠或免疫球蛋白;親水性聚合物,諸如聚乙烯吡咯啶酮;胺基酸,諸如甘胺酸、麩醯胺酸、天冬醯胺酸、組胺酸、精胺酸或離胺酸;單醣、二糖及其他碳水化合物,包括葡萄糖、甘露糖或糊精;螯合劑,諸如EDTA;糖類,諸如蔗糖、甘露糖醇、海藻糖或山梨糖醇;形成鹽之相對離子,諸如鈉;金屬錯合物(例如鋅-蛋白質錯合物);及/或非離子型介面活性劑,諸如TWEEN™、PLURONICS™或聚乙二醇(PEG)。
非經腸投與之醫藥組合物較佳為無菌及實質上等滲的,且在優良製造規範(GMP)條件下製造。醫藥組合物可呈單位劑型(亦即單次投與之劑量)提供。調配物視所選擇之投藥途徑而定。本文中之抗體可藉由靜脈內注射或輸注或皮下來投與。對於注射投與,本文中之抗體可調配在水溶液中,較佳在生理相容之緩衝液中以減少注射部位之不適。溶液可含有如上所論述之載劑、賦形劑或穩定劑。可替代地,抗體可呈凍乾形式,以供在使用前用合適媒劑,例如無菌無熱原水復原。
抗體調配物揭示於例如美國專利第9,034,324號中。類似調配物可用於本發明之重鏈抗體,包括UniAbs™。皮下抗體調配物描述於例如US20160355591及US20160166689中。
使用方法
本文所述之抗FOLR1抗體及醫藥組合物可用於治療以FOLR1表現為特徵之疾病及疾患,包括但不限於本文進一步描述之疾患及疾病。
FOLR1,亦稱FRα (UniProt P15328;HGNC ID 3791),係一種糖基磷脂醯肌醇(GPI)連接之膜蛋白,其結合於葉酸及還原之葉酸衍生物且介導5-甲基四氫葉酸之細胞內遞送。FOLR1具有在中性pH值下對葉酸具有高親和力的210個胺基酸之細胞外域(ECD)。內化後,酸性pH值會導致FOLR1發生構形變化,此變化降低FOLR1對葉酸之親和力,從而介導葉酸之釋放,隨後FOLR1再循環至細胞表面。Wibowo AS等人
Proc Natl Acad Sci USA. 2013年9月17日;110(38):15180-8。FOLR1在許多實體腫瘤類型中過度表現,包括卵巢、乳房、肺、腎、結腸直腸及腦,但FOLR1在諸如腎、肺、視網膜及腦之正常健康組織中的表現僅限於上皮之頂面,從而減少其暴露於循環中之FOLR1靶向劑且使FOLR1成為有吸引力之治療標靶。Cheung A等人
Oncotarget. 2016年8月9日;7(32):52553-52574。FOLR1亦可能與FOLR1陽性腫瘤之成像及診斷有關,且此外,據報導,在卵巢癌患者中可溶性FOLR1升高。Kurosaki A等人

在一個態樣中,本文中之抗FOLR1抗體(例如UniAbs™)及醫藥組合物可用於治療以FOLR1表現為特徵之病症,包括但不限於實體腫瘤,例如癌,諸如卵巢癌及子宮癌(例如高惡性度漿細胞癌、子宮內膜樣癌、低惡性度漿細胞癌、透明細胞癌、黏液癌及子宮內膜癌)、肺癌、腎癌、結腸直腸癌、乳癌以及腦癌(例如,神經膠瘤、神經膠質母細胞瘤)。
本發明之組合物用於治療疾病之有效劑量視許多不同因素而變,包括投藥方式、標靶部位、患者之生理狀態、患者係人類還是動物、投與之其他藥物以及治療係預防性還是治療性。通常,患者為人類,但亦可治療非人類哺乳動物,例如,諸如狗、貓、馬等伴侶動物,諸如兔、小鼠、大鼠等實驗室哺乳動物,及其類似動物。可調整治療劑量以優化安全性及功效。
劑量水準容易由普通熟練之臨床醫生確定,且可根據需要,例如根據修改個體對療法之反應之需要進行修改。可與載劑材料組合以產生單一劑型之活性成分之量視所治療之宿主及特定投藥模式而定。單位劑型通常含有約1 mg至約500 mg之間的活性成分。
在一些實施例中,藥劑之治療劑量可在約0.0001至100 mg/kg,且更通常為0.01至5 mg/kg宿主體重範圍內。例如,劑量可為1 mg/kg體重或10 mg/kg體重或在1-10 mg/kg範圍內。一示例性治療方案需要每兩週投與一次或每月投與一次或每3至6個月投與一次。本發明之治療實體通常多次投與。單次劑量之間的時間間隔可為一週、一個月或一年。時間間隔亦可為不規則的,如藉由量測患者體內治療實體之血液水準所指示。可替代地,本發明之治療實體可作為持續釋放製劑投與,在此情況下需要較低投與頻率。劑量及頻率視患者體內多肽之半衰期而定。
通常,組合物製備為注射劑,呈液體溶液或懸浮液;亦可製備適合在注射前溶解或懸浮在液體媒劑中之固體形式。本文中之醫藥組合物適用於直接或在復原固體(例如凍乾)組合物之後靜脈內或皮下投與。如上所論述,製劑亦可乳化或囊封在脂質體或諸如聚丙交酯、聚乙交酯或共聚物之微粒中以增強佐劑作用。Langer, Science 249: 1527, 1990及Hanes, Advanced Drug Delivery Reviews 28: 97-119, 1997。本發明之藥劑可呈儲槽注射製劑或植入製劑之形式投與,其可以允許活性成分持續或脈衝釋放之方式進行調配。醫藥組合物通常調配成無菌、實質上等滲且完全符合美國食品及藥物管理局(U.S. Food and Drug Administration)之所有優良製造規範(GMP)規定。
本文所述之抗體及抗體結構之毒性可藉由細胞培養物或實驗動物中之標準醫藥程式,例如藉由測定LD50 (對群體50%致死之劑量)或LD100 (對群體100%致死之劑量)來確定。毒性與治療作用之間的劑量比係治療指數。自此等細胞培養分析及動物研究中獲得之資料可用於調配對人類無毒之劑量範圍。本文所述之抗體之劑量較佳位於包括毒性很小或無毒性之有效劑量的循環濃度範圍內。劑量可在此範圍內變化,視所採用之劑型及所利用之投藥途徑而定。確切之調配物、投藥途徑及劑量可由個別醫師根據患者之狀況來選擇。
用於投與之組合物通常包含溶解在醫藥學上可接受之載劑,較佳水性載劑中之抗體或其他消融劑。可使用多種水性載劑,例如緩衝鹽水及其類似物。此等溶液係無菌的且通常不含不需要之物質。此等組合物可藉由習知之熟知滅菌技術進行滅菌。組合物可含有根據接近生理條件之需要的醫藥學上可接受之輔助物質,諸如pH調節劑及緩衝劑、毒性調節劑及其類似物,例如乙酸鈉、氯化鈉、氯化鉀、氯化鈣、乳酸鈉及其類似物。此等調配物中活性劑之濃度可廣泛變化,且將主要基於流體體積、黏度、體重及其類似因素根據所選擇之特定投藥模式及患者之需要進行選擇(例如,Remington's Pharmaceutical Science (第15版, 1980)及Goodman及Gillman, The Pharmacological Basis of Therapeutics (Hardman等人編輯, 1996))。

實例 15 : FOLR1 在正常及惡性細胞上之表現
FOLR1 (FRα)在正常健康組織(包括肺及腎)上表現,且用T細胞銜接劑(TCE)靶向FOLR1可能會導致靶向非腫瘤毒性。對FOLR1在各種卵巢及其他實體腫瘤細胞株以及正常初級細胞上之細胞表面表現進行定量。藉由流動式細胞測量術定量FOLR1陽性腫瘤細胞株細胞表面上FOLR1分子之數目(抗原密度)。卵巢腫瘤細胞株OVCAR-3、SKOV-3及IGROV-1上之FOLR1抗原密度在44×10
3至1,871×10
3(圖11)範圍內,囊括在復發性卵巢癌患者之臨床樣品中觀測到之範圍。相反,正常初級肺泡及支氣管上皮肺細胞分別表現0.1×10

3及1.3×10
3範圍內。由於據報導表現FOLR1之正常組織上之表現上限在7×10
3範圍內,因此選擇具有8×10

實例 16 :細胞表面親和力及腫瘤細胞溶解
評估一種與FOLR1 (FRα)及CD3結合之完整人類雙特異性抗體,稱為TNB-928B,評估其細胞表面結合特徵及溶解FOLR1+腫瘤細胞之能力。圖12之圖A提供TNB-928B之示意圖,其係使用杵臼技術構築。該示意圖展示抗體之格式。圖12之圖B展示TNB-928B對IGROV-1細胞上表現之FOLR1 (FRα)之細胞表面親和力(如藉由斯卡查德分析(Scatchard analysis)確定)。圖12之圖C展示與T細胞之共培養細胞毒性分析之結果(E:T比率為10:1),顯示48小時後IGROV-1腫瘤細胞之細胞溶解。

評估TNB-928B誘導高FOLR1 (FRα)表現之腫瘤細胞之選擇性溶解同時保留低FOLR1表現之細胞的潛力。進行與來自健康供體之T細胞(10:1之E:T比率)之共培養細胞毒性分析。結果展示於圖14中。圖A顯示48小時後SKOV-3腫瘤細胞(高FOLR1表現)之細胞溶解。圖B顯示48小時後HT-29細胞(低FOLR1表現)之細胞溶解。結果表明,TNB-928B誘導高FOLR1 (FRα)表現之腫瘤細胞之選擇性裂解,同時保留低FOLR1表現之細胞。
實例 19 :腫瘤細胞溶解伴隨有低細胞介素釋放
評估TNB-928B誘導腫瘤細胞溶解而不誘導高水準細胞介素釋放之潛力。進行與來自三名健康供體之T細胞(5:1之E:T比率)之共培養細胞毒性分析。自細胞毒性分析收集細胞培養上清液之等分試樣,且分析IL-2及IFNγ細胞介素之釋放。在介導IGROV-1及SKOV-3強烈溶解之TNB-928B濃度下,IL-2及IFNγ之水準低於由含有PC之OKT3誘導之水準,無論供體如何(圖15)。此外,當針對FOLR1 (FRα)陰性LNCaP細胞株進行測試時,TNB-928B未展現細胞毒性,亦未展現IL-2或IFNγ釋放(圖15)。
實例 20 :患者來源之卵巢腫瘤中腫瘤細胞溶解及 T 細胞活性之介導
評估TNB-928B在患者來源之卵巢腫瘤細胞中介導腫瘤細胞溶解及T細胞活性之潛力。將TNB-928B、PC或NC添加至新鮮分離之卵巢癌組織中,且在不添加外源PBMC下培育48至72小時。結果提供於圖16中。圖A展示來自用10 nM PC、100 nM TNB-928B或100 nM NC治療之5名不同反應患者之卵巢癌組織來源細胞的最大細胞毒性。圖B顯示,反應者之FOLR1 (Frα)表現比無反應者高。圖C展示如藉由LDH釋放量測之細胞毒性之代表性劑量曲線,圖D展示IFNγ釋放,且圖E展示如藉由MSD量測之IL-2釋放。圖F展示如在與患者匹配之PBMC以1:1之E:T比率一起培育72小時後藉由流動式細胞測量術量測的CD69

實例 21 : NCG 小鼠異種移植模型中之劑量依賴性腫瘤消退
評估TNB-928B在NCG小鼠異種移植模型中以劑量依賴性方式誘導腫瘤消退之潛力。模型及結果之細節提供於圖17中。將5×10
6個IGROV-1細胞皮下注射及10×10
6個休眠hPBMC皮下注射至NCG小鼠中(n=3/組)。自植入後(pi)第3天開始,TNB-928B以各別劑量(用向下箭頭展示)每3天靜脈內注射一次,總共9個劑量。圖A中提供該研究之示意圖。在第30天收穫腫瘤且藉由IHC用抗人類CD3、抗人類CD45及抗人類FRα染色。對染色陽性細胞進行定量,且結果展示於圖B中。在BALB/c小鼠中,在以1及10 mg/kg單次尾靜脈注射後評估TNB-928B之PK。TNB-928B清除率(CL)在7.9至10.3毫升/天/公斤範圍。TNB-928B之半衰期(t
1/2)為3.9至8天(圖17之圖C)。由於TNB-928B之兩個臂皆不與嚙齒動物物種中之FOLR1 (FRα)或CD3發生交叉反應,因此預期觀測到線性PK且與非特異性清除機制一致。此等結果表明TNB-928B在活體內穩定,具有良好PK及與習知抗體相似之半衰期。
實例 22 :熱應力及穩定性表徵
評估TNB-928B之生物物理特徵,且結果總結在圖18及圖21中。所有抗體皆在20 mM檸檬酸鹽及0.1 M NaCl pH 6.2中調配。藉由SEC-UPLC (ThermoFisher UltiMate™
3000 HPLC)在溫度應力之前(T
0)及在37℃下1個月的溫度應力之後(T
30)量測高分子量物質(HMW)。圖18中展示T = 0天及T = 30天之低分子量(% LMW)及高分子量(% HMW)百分比。在4℃及37℃下培育1個月後,評估TNB-928B之穩定性。SEC-UPLC層析圖展示於圖21中。
實例 23 : FOLR1 價數之影響
為在細胞毒性分析中確定FOLR1 (FRα)價數對FOLR1×CD3 TCE之活體外功能活性之影響,將IGROV-1 (高FRα抗原密度)細胞與初級人類泛T細胞以及FOLR1 TCE共培養48小時。將TNB-928B介導IGROV-1溶解之能力與含有相同VH之對FOLR1呈單價之相應雙特異性抗體進行比較。在IGROV-1腫瘤細胞存在下,TNB-928B及二價PC抗體皆表現出親合力效應,該親合力效應係在與各別單價抗體相比較低之EC
50值(效力增加)中觀測到(圖19)。重要地,與飽和劑量之PC相比,TNB-928B表現出相似的最大腫瘤細胞溶解,IGROV-1溶解約75%。綜上所述,此等資料表明,TNB-928B之二價格式在殺死高FOLR1表現之腫瘤細胞上表現出強親合力效應,且TNB-928B實現與PC相當之最大活性。
實例 24 :離體卵巢腫瘤樣品之臨床及分子特徵
評估新鮮的患者來源之離體卵巢腫瘤樣品之臨床及分子特徵,且結果提供於圖20中。標題為「TNB-928B最大溶解%」之行表示來自用100 nM TNB-928B處理48至72小時之樣品的資料。縮寫:HGSC,高惡性度漿細胞癌;HGC,高惡性度癌;LGESS,低惡性度子宮內膜間質肉瘤;LGSC,低惡性度漿細胞癌;nd,未確定。
實例 25 :在低 E:T 比率及存在 sFOLR1 下之活性
與其他GPI錨定蛋白一樣,FOLR1自細胞表面裂解。在卵巢癌患者之血清中可溶性FOLR1蛋白(sFOLR1;sFRα)升高,且在早期及晚期卵巢癌患者中,高sFOLR1與較短之PFS相關聯(Kurosaki A, Hasegawa K, Kato T, Abe K, Hanaoka T, Miyara A等人

Clin Biochem2013;
46(15):1462-8)。此外,腫瘤細胞上FOLR1之表現與sFOLR1水準密切相關。為確定sFOLR1對TNB-928B介導之腫瘤細胞溶解的影響,在外源添加之10 ng/mL、100 ng/mL及1,000 ng/mL可溶性重組FOLR1存在下,用T細胞及SKOV-3細胞進行細胞毒性分析。在高達1,000 ng/mL (此比在EOC患者血清中量測之sFOLR1高約100倍) sFOLR1存在下,偵測到TNB-928B介導之SKOV-3腫瘤細胞溶解的效力降低程度最低(Kurosaki A, Hasegawa K, Kato T, Abe K, Hanaoka T, Miyara A等人

6(1):29),但最大細胞溶解未變化(圖22之圖B)。為確定外源sFOLR1在細胞毒性分析期間是否穩定,在48小時後藉由ELISA對代表性孔之細胞培養上清液中之sFOLR1水準進行定量。48小時後量測之sFOLR1水準與外源sFOLR1之量相當(圖22之圖C)。此等資料表明,TNB-928B之細胞毒活性不受與卵巢癌患者血清中偵測到之生理水準相當之sFOLR1水準影響。
實例 26 :細胞毒性顆粒之產生
在患者來源樣品中藉由獲得新鮮的手術切除之卵巢腫瘤切片來評估TNB-928B介導之細胞毒性。將離體卵巢腫瘤樣品與TNB-928B、PC或NC培育48至72小時。TNB-928B介導大量離體腫瘤細胞溶解,與自八位不同患者中五位分離之卵巢腫瘤樣品中之PC相當(圖16及20)。重要地,此等樣品中未添加外源T細胞,此表明腫瘤中存在之內源T細胞足以介導腫瘤細胞之細胞毒性。對八個患者樣品中之六個量測FOLR1抗原密度,且發現樣品之間顯示 < 10% (無反應者)及 > 10% (反應者)腫瘤溶解的趨勢(圖16之圖B)。兩個無反應者之FOLR1抗原密度 < 1×10
3(圖20),因此基於活體外結果,預計不會顯示活性。在代表性的分離之卵巢腫瘤樣品中,TNB-928B之EC50為45.2 pM,與活體外結果一致(圖16之圖C)。亦與活體外細胞毒性結果一致的是,如藉由IFNγ及IL-2量測,與PC相比,TNB-928B誘導之細胞介素釋放水準降低(圖16之圖D及E)。此外,TNB-928B介導之腫瘤細胞溶解伴隨有細胞毒性顆粒之釋放,其中上清液中穿孔蛋白及顆粒酶B之水準與PC相當(圖23之圖A及B)。重要地,當分離之卵巢腫瘤樣品與患者匹配之PBMC以1:1之E:T比率一起培育時,與PC相比,TNB-928B誘導之Treg細胞活化減少約2.5倍(圖16之圖F)。此等資料表明,TNB-928B介導對表現高水準FRα之原發患者腫瘤樣品之強大卵巢腫瘤細胞殺死,將細胞毒性與細胞介素釋放分離,且優先活化效應T細胞而非Treg細胞。
