- a mask antibody is known as a modified antibody that specifically acts on tumor tissue by using the properties of the tumor microenvironment (enhanced protease activity in tumor tissue, etc.). Since masked antibodies have suppressed binding activity in normal tissues, they are expected to be highly safe antibody drugs with low toxicity to normal tissues via target molecules (Non-Patent Document 2).
- a masked antibody is composed of an antibody body, a masking domain that inhibits antibody binding, and a cleavable linker that connects the antibody and the masking domain and can be cleaved by a protease (Patent Document 1).

本明細書は本願の優先権の基礎となる日本国特許出願番号2021-194701号の開示内容を包含する。
本発明において「DXd」とは、「N-[(1S,9S)-9-Ethyl-5-fluoro-9-hydroxy-4-methyl-10,13-dioxo-2,3,9,10,13,15-hexahydro-1H,12H-benzo[de]pyrano[3’,4’:6,7]indolizino[1,2-b]quinolin-1-yl]-2-hydroxyacetamide」を意味する。
本発明において、「分子」は、上述の抗体、抗体の抗原結合断片を含む分子であり、さらに抗体又はそれらに由来する複数の抗原結合断片より形成された多重特異的である分子を含む。
本発明は、標的抗原に結合する分子であって、特定の環境で前記標的抗原に特異的に結合する分子である。
本発明の抗体としては、非ヒト動物由来の抗体(非ヒト動物抗体)、ヒト抗体、キメラ化抗体(「キメラ抗体」ともいう)、ヒト化抗体などを挙げることができ、好ましくはヒト抗体又はヒト化抗体を用いることができる。本発明の抗体の範囲には、抗体の変異体(後述の「変異抗体」)も含まれ、例えば、ヒト抗体の範囲には、ヒト変異抗体も含まれ、ヒト化抗体の範囲には、ヒト化変異抗体も含まれる。
本発明の抗体又はその抗原結合断片の変異体には、好適には、蛋白質の分解若しくは酸化に対する感受性の低下、生物活性や機能の維持、改善若しくは低下や変化の抑制、抗原結合能の改善若しくは調節、又は理化学的性質若しくは機能的性質の付与等がなされ得る。蛋白質は、その表面にある特定のアミノ酸側鎖が変化して当該蛋白質の機能や活性が変化することが知られ、そのような例には、アスパラギン側鎖の脱アミド化、アスパラギン酸側鎖の異性化等が含まれる。そのようなアミノ酸側鎖の変化を防ぐために別のアミノ酸に置き換えたものも、本発明の変異体の範囲に含まれる。
本発明は、抗体又はその結合断片の修飾体を提供する。本発明の抗体又はその結合断片の修飾体とは、本発明の抗体又はその結合断片に化学的又は生物学的な修飾が施されてなるものを意味する。化学的な修飾体には、アミノ酸骨格への化学部分の結合、N-結合又はO-結合炭水化物鎖の化学修飾体等が含まれる。生物学的な修飾体には、翻訳後修飾(例えば、N-結合又はO-結合への糖鎖付加、糖鎖リモデリング、アミノ末端領域又はカルボキシル末端領域のプロセッシング、脱アミド化、アスパラギン酸の異性化、メチオニンの酸化)されたもの、原核生物宿主細胞を用いて発現させることによりアミノ末端にメチオニン残基が付加したもの等が含まれる。また、本発明の抗体又は抗原の検出又は単離を可能にするために標識されたもの、例えば、酵素標識体、蛍光標識体、アフィニティー標識体もかかる修飾物の意味に含まれる。このような本発明の抗体又はその結合断片の修飾物は、元の本発明の抗体又はその結合断片の安定性及び血中滞留性の改善、抗原性の低減、かかる抗体又は抗原の検出又は単離等に有用である。
標的抗原とは、特定の疾患に関連した分子をいう。特定の疾患に関連した分子とは、該疾患の原因となっている抗原や分子の疾患に罹患した場合に、該疾患において出現する異常細胞において、発現するか、又は発現が亢進する分子をいう。該分子に上記の標的抗原に結合する部分が結合することにより、異常細胞を攻撃し、疾患の症状を軽減し、又は疾患を治療し得る分子をいう。前記異常細胞は、好ましくは腫瘍細胞や間質細胞であり、標的抗原は、腫瘍細胞については、腫瘍抗原であり、間質細胞については、間質細胞上に発現している分子である。間質細胞は、腫瘍細胞と相互作用を行い、がんの増殖及び進行に大きな役割を果たす。腫瘍抗原は、腫瘍細胞に発現している抗原又は正常細胞ががん化した腫瘍細胞に発現する抗原であり、上記の標的抗原に結合する部分が腫瘍抗原に結合することにより、腫瘍細胞の増殖を阻害し、腫瘍細胞を傷害し、又は腫瘍細胞を死滅(アポトーシス又はネクローシス)させる。
標的抗原に結合する部分([a]部分)に含まれる該標的抗原結合部位を認識する第1ペプチドは、標的抗原に結合する部分に含まれる該標的抗原結合部位を認識することにより、該部位をマスクし、標的抗原に結合する部分が標的抗原に結合できなくする、結合し難くする、又は、結合するのを阻害もしくは妨害するペプチドである。標的抗原に結合する部分が抗体又は抗体の抗原結合断片(以下「抗体等」という。)である場合、第1ペプチドは抗体等の抗原との結合領域に結合するペプチドである。抗体等の抗原との結合領域は、抗体等の可変領域、特に相補性決定領域(CDR)に存在する。抗体等は抗原のエピトープ(抗原決定基)と結合するので、第1ペプチドはエピトープを模倣したペプチドである。抗原のエピトープを模倣(mimic)したペプチドをミモトープ(Mimotope)といい、本発明において、前記第1ペプチドは、好ましくはCDRに結合するミモトープである。ミモトープは、6~30個、好ましくは10~20個、さらに好ましくは13~17個、特に好ましくは15個のアミノ酸からなるペプチドである。ミモトープは、例えば、上記のアミノ酸数からなる各種ディスプレイ(ファージディスプレイ、リボソームディスプレイ、核酸ディスプレイ、細菌ディスプレイ等)・ライブラリーを作製し、パニングによりスクリーニングを行うことにより、標的抗原に結合する部分に含まれる該標的抗原結合部位を認識するペプチドを提示するファージ粒子を選別し、該ファージ粒子からミモトープをコードするDNA及びそのヌクレオチド配列を得て製造することができる。ペプチドがミモトープであること(抗体のCDRに結合していること)は、例えば、マスク抗体、又は抗体と当該ペプチドの複合体を結晶化して、X線結晶構造解析を行うことにより確認できる。また、ペプチドが抗体に対し抗原と(競合的に)結合することをSPR等により確認できれば、当該ペプチドは当該抗体のCDRに結合するミモトープであることが強く示唆される(実施例4参照)。
細胞質内に局在するプロテアーゼにより切断されるアミノ酸配列を含む第2ペプチドは、細胞質内に局在するプロテアーゼの基質となり、該プロテアーゼにより切断されるアミノ酸配列を含む。該プロテアーゼは、第2ペプチドに含まれるアミノ酸配列を認識して切断する。本発明においては「細胞質内に局在するプロテアーゼ」を「細胞内プロテアーゼ」とも呼び、2つの用語は互換性がある。第2ペプチドを「切断リンカー」とも呼ぶ。
本発明の標的抗原に結合する分子は、標的抗原に結合する部分([a]部分)、該部分に含まれる該標的抗原結合部位を認識する第1ペプチド([b]部分)、及び、細胞質内に局在するプロテアーゼにより切断されるアミノ酸配列を含む第2ペプチド([c]部分)を含み、好ましくはそれらが直接又は間接的に連結した状態で存在し、第1ペプチドが、標的抗原に結合する部分中の標的抗原結合部位に結合することにより、該標的抗原結合部位をマスクする。この結果、該標的抗原結合部位は、標的抗原に結合することができないか又は結合し難い。図1Aは、標的抗原に結合する部分が2価の抗体(IgG)であり、第2ペプチドが細胞外プロテアーゼ用基質(第2切断アミノ酸配列、図1Aの灰塗り部分)及び細胞内プロテアーゼ用基質(第1切断アミノ酸配列、図1Aの黒塗り部分)が連結したペプチドである分子であり、図1Aの格子柄で示された第1ペプチドが抗体の抗原との結合部位に結合し該部位をマスクしている。第1ペプチドは、標的抗原結合部位を認識し結合し得るが、第2ペプチドが切断され、第1ペプチド単独で存在する場合、物理化学的条件により、結合、解離するので、永続的に結合していることはできないと考えられる。例えば、本発明の標的抗原に結合する分子においては、第1ペプチドは、第2ペプチドを介して標的抗原に結合する部分に結合しているので、標的抗原に結合する分子は、第1ペプチドの位置が標的抗原に結合する部分に含まれる該標的抗原結合部位の近傍に位置するようなコンフォメーションをとり、第1ペプチドは、分子のコンフォメーションが変化しない限り、平衡条件では標的抗原結合部位の大部分がマスクされているといった作用機序をとると想定することができるが、かかる機序はそれに限定されない。
本発明の標的抗原に結合する分子は、さらに他の部分を含んでいてもよい。本発明においては、かかる他の部分のことを「[d]部分」ともいう。[d]部分は、前記分子の標的抗原結合部分に結合する。[d]部分は、該標的抗原結合部分ではない抗体若しくはその抗原結合断片、第1ペプチド及び第2ペプチドに含まれないアミノ酸配列を含むペプチド、サイトカイン、毒素、放射性同位元素、標識分子、光感受性物質(photosensitizer:「光増感剤」ともいう)、免疫賦活化物質、抗腫瘍性化合物、薬物、ペイロード並びにポリマーからなる群より選択される1つ又は2つ以上の化合物からなる。
(1)第1ペプチドに含まれるミモトープの同定方法
任意の抗体又はその抗原結合断片に含まれる相補性決定領域(CDR)に結合するペプチドを、ペプチドライブラリーを利用して同定することができる。ペプチドライブラリーは公知の方法で構築すればよい。例えば、完全ランダムなアミノ酸から構成されるリボソーム等の各種ディスプレイ用のペプチドライブラリーを構築し、前記CDRに親和性の大きいペプチドを選択すればよい。また、中央付近に芳香族性アミノ酸とProの繰り返しモチーフ(ZPZPモチーフ)をもつ各種ディスプレイ用のペプチドライブラリー(ZPZP lib)を構築し、前記CDRに親和性の大きいペプチドを選択すればよい。ここで、Zはヒスチジン(His)、フェニルアラニン(Phe)、チロシン(Tyr)、トリプトファン(Trp)のいずれかの芳香族アミノ酸を表し、Pはプロリンを表す。
抗体のCDRループは、芳香族アミノ酸が多く含まれる。芳香族アミノ酸同士は相互作用しやすいため、ペプチドの中央付近に芳香族アミノ酸が存在していることが好ましい。
本発明の標的抗原に結合する分子であり、第1ペプチドに含まれるアミノ酸配列及び/又は第2ペプチドに含まれるアミノ酸配列を含んでなるペプチドは、組換え、インビトロ翻訳、化学合成、ペプチド合成等により調製することができる。
本発明の標的抗原に結合する分子、その塩又はそれらの水和物(以下「本発明の標的抗原に結合する分子等」という。)は、異常細胞に起因する疾患の予防又は治療薬として用いることができる。
1)-1 抗TROP2抗体HT1-11の発現・精製
WO2015/098099号に記載の公知の抗TROP2抗体の重鎖(図26、配列番号1)または軽鎖(図27、配列番号2)をコードするDNAがクローニングされたpcDNA3.3(Thermo Fisher Scientific社)を骨格とした哺乳動物細胞用発現ベクターをExpi293F細胞に導入し、一過性発現させた培養上清より抗体分子を精製した。Expi293F細胞(Thermo Fisher Scientific社)はマニュアルに従い、継代、培養を行った。対数増殖期にあるExpi293F細胞培養液を2.5×106 cells/mLになるようExpi293 Expression medium(Thermo Fisher Scientific社)で希釈し、Opti-Pro SFM培地(Thermo Fisher Scientific社)に重鎖、軽鎖それぞれの発現ベクターとPolyethyleneimine(Polyscience社)を加えて反応後、Expi293F細胞へ添加した。37℃、8%CO2インキュベーターで5日間、135rpmで振とう培養した。遠心分離後の培養上清に対してPBS pH7.4で平衡化したMabSelectSuRe(Cytiva社)を添加し、目的の抗体分子を吸着させた。非吸着成分をPBSで除去した後、pH3.5の酢酸バッファーで吸着成分を溶出した。溶出画分はpH9.0のTrisバッファーでpHを中性に調製し、限外ろ過膜を用いて25mM Histidine、5(w/v)% Sorbitor、pH6.0にバッファー置換した。必要に応じて濃縮後、予め25mM Histidine、300mM NaCl、5(w/v)% Sorbitor、pH5.5で平衡化したゲルろ過カラムSuperdex 200 Increase(Cytiva社)に供し、モノマー画分を回収した。精製サンプルは、SDS-ポリアクリルアミド電気泳動(SDS-PAGE)と分析用サイズ排除クロマトグラフィー(SEC)に供し、モノマー純度を評価した。精製抗体の濃度は、分光光度計の280nmの吸光度と、PACE法で算出した吸光係数を用いて当業者公知の方法で決定した(Protein Science.;4(11):2411-2423(1995))。
96ウェルMaxi-sorp plate(Black、Nunc社)にPBSで1μg/mLに希釈したNeutrAvidin(Thermo Fisher Scientific社)を50μLずつ添加し、4℃で一晩固相化した。Tween-20(Bio-Rad社)を0.05(w/v)%含むPBS(ELISAバッファー)で洗浄後、Blocker Casein(Thermo Fisher Scientific社)でブロッキングした。ELISAバッファーで洗浄後、PBSで1μg/mLに希釈したビオチン化ヒトTROP2抗原(アクセション番号:P09758。細胞外ドメインを当業者公知の手法で精製後、C末端Aviタグ配列をビオチン化した。)を50μLずつ添加して30分室温で振とうした。ELISAバッファーで洗浄後、ELISAバッファーで濃度調整した実施例1)-1の抗体を50μLずつ添加して30分室温で振とうした。ELISAバッファーで洗浄後、ELISAバッファーで2500倍に希釈したHorseradish peroxidase(HRP)標識抗ヒトIgG抗体(Jackson Immuno Research Laboratories社)を50μL添加し、30分室温で振とうした。ELISAバッファーで洗浄後、SuperSignal Pico ELISA Chemiluminescent substrate(Thermo Fisher Scientific社)を添加し、10分後の化学発光をプレートリーダーで測定した。図2に示すように、HT1-11は濃度依存的にヒトTROP2抗原に結合した。
完全ランダムな15アミノ酸から構成されるリボソームディスプレイ用のペプチドライブラリー(Linear 15mer lib)を構築し、当業者公知の方法でHT1-11へ結合可能なペプチドを濃縮した。最初に、EZ-Link NHS-PEG4-Bioin(Thermo Fisher Scientific社)でビオチン化したヒト血清由来IgG(Sigma-Aldrich社)またはHT1-11をDynabeads Streptavidin M-280(Thermo Fisher Scientific社)に固相化し、ペプチドを提示しているリボソーム(ribosome displaying peptide:以下「RD」という。)をヒト血清由来IgG結合ビーズと反応させた。結合しなかったRDをマグネットスタンド(DynaMag‐2、Thermo Fisher Scientific社)を用いて回収後、HT1-11結合ビーズと反応させた。マグネットスタンドを用いた洗浄操作によりHT1-11に結合しなかったRDを除去し、HT1-11に結合したRDからmRNAを精製した。その後、RT-PCRおよびインビトロ翻訳によりRDを再度調製した。このパニング操作を3回実施した。
3)-1 パニング由来のペプチドを融合したHT1-11 scFvの調製
パニング3ラウンド後のDNAフラグメントに制限酵素を添加し、ランダムペプチド部分をコードするDNAフラグメントを当業者公知の方法で精製した。pelBシグナル配列、DNAフラグメント、MMP切断リンカー(公知のMMP基質含む(Journal of Controlled Release.;161:804-812(2012).):配列番号3及び図28に示されるアミノ酸配列のアミノ酸番号41~60)、HT1-11 scFv(VH-VLの順または、VL-VHの順)、FLAGタグ、Hisタグの順で翻訳されるように、当業者公知の方法でDNAフラグメントを大腸菌発現ベクターにライゲーションし、大腸菌XL-1 Blue(Agilent Technologies社)を形質転換した。IPTG(Isopropyl-β-D-thiogalactopyranoside)(Sigma-Aldrich社)存在下で大腸菌を培養し、ペプチド融合scFvを含む培養上清を回収した。
実施例1)-2と同様の方法でヒトTROP2抗原に対する結合活性をELISAで評価した。ペプチド融合scFvを含む培養上清は、2mMの塩化カルシウムを含むTBS(MMPバッファー)で10倍希釈し、100nMの活性型ヒトMMP1(アクセション番号:P03956)と37℃で15分反応させ、MMP切断リンカーを切断した。その後、ヒトTROP2抗原を固相化したプレートに50μLずつ添加した。結合したscFvはELISAバッファーで5000倍に希釈したHRP標識抗FLAG抗体(Sigma-Aldrich社)で検出した。また、MMP1非添加条件でも同様の操作を行い、結合強度比(MMP1添加条件/MMP1非添加条件)が大きい値を示すクローンを陽性クローンとして選抜した。陽性クローンの発現ベクターを精製後、当業者公知の方法で翻訳領域の配列を解析し、ユニーククローンとしてMHT1001(図28、配列番号3)およびMHT1002(図29、配列番号4)を得た。
HT1-11―scFv-HL(図30、配列番号5)、HT1-11-scFv-LH(図31、配列番号6)および実施例3)-2で同定した陽性クローンMHT1001、MHT1002を大腸菌XL-1 Blueで発現させ、培養上清よりNi Sepharose excel(Cytiva社)で精製し、TBSに置換した。精製抗体の濃度は、分光光度計の280nmの吸光度と、PACE法で算出した吸光係数を用いて当業者公知の方法で決定した(Protein Science.;4(11):2411-2423(1995))。精製サンプルを用いて実施例3)-2と同様の方法でMMP1添加条件、MMP1非添加条件におけるヒトTROP2抗原に対する結合活性をELISAで評価した。MMPバッファーで抗体を1μMに調製し、終濃度1μMまたは0μMになるようMMP1を添加し、37℃で15分反応させた。その後、ELISAバッファーで濃度調整した抗体を各ウェルに添加した。
当業者公知の手法で、MHT1001のミモトープペプチドおよびMMP切断リンカー(実施例3)-1参照)を融合した抗TROP2マスク抗体MHT1007(表1、図32、配列番号7)の重鎖発現ベクターを構築した。同様に、MMP切断リンカーの部分をプロテアーゼで切断できない非切断リンカーに改変したMHT1008(表1、図33、配列番号8)およびuPAの切断リンカー(公知のuPA基質含む(Journal of Biological Chemistry.;272(33):20456-20462(1997).):図34及び配列番号9で示されるアミノ酸配列のアミノ酸番号36~55)に改変したMHT1009(表1、図34、配列番号9)の重鎖発現ベクターをそれぞれ構築した。各抗体の重鎖発現ベクターをHT1-11の軽鎖発現ベクターを組合せ、実施例1)-1と同様の方法でExpi293F細胞の培養上清より各マスク抗体を精製し、蛋白質濃度を決定した。調製したマスク抗体は重鎖発現ベクター名と対応させ、MHT1007、MHT1008、MHT1009と命名した(表1)。
5)-1 CAPN切断配列の改変
細胞質に局在するCAPNは、細胞死に伴い細胞外へ漏出することが示唆されている(非特許文献7)。細胞内プロテアーゼであるCAPNの基質配列と、細胞外プロテアーゼであるuPAの基質配列を組合せることで、uPA基質のみを搭載した場合と比較して、マスク抗体の結合活性を向上させられるか検証するために、適切なCAPNの基質配列を設計した。アミノ酸配列PLFAAR(配列番号10、図35のアミノ酸番号47~52)で構成される公知のCAPN基質(Biochimica et Biophysica Acta.;1794(10):1505-1509(2009).)を切断リンカー内に搭載した抗TROP2マスク抗体MHT3002(表1、図35、配列番号10)を調製し、以下に記載する部分を除き、実施例4と同様の方法でプロテアーゼ添加条件、非添加条件におけるヒトTROP2抗原に対する結合活性をELISAで評価した。MMPバッファーでマスク抗体を10nMに希釈後、200nMのuPAまたはCAPN1(Novus Biologicals社(図36、配列番号11))を添加し、37℃で反応後、ヒトTROP2抗原の固定されたウェルに添加した。
公知のuPA基質(Journal of Biological Chemistry.;272(33):20456-20462(1997).)と新規CAPN基質(PLFAAP)の両方を切断リンカー内に搭載したMHT3202(表1、図39、配列番号14)と、上記uPA基質とPLGLWAで構成される公知のMMP基質(Biopolymers.;40(4):399-416(1996).)を搭載したMHT1713(表1、図40、配列番号15)を調製し、ヒトMMP1(アクセション番号:P03956)、ヒトMMP2(アクセション番号:P08253)、ヒトMMP3(アクセション番号:P08254)、ヒトMMP7(アクセション番号:P09237)、ヒトMMP9(アクセション番号:P14780)、ヒトMMP12(アクセション番号:P39900)、ヒトMMP14(アクセション番号:P50281)で活性化されるかどうか、以下に記載する部分を除き、実施例5)-1と同様にELISAで評価した。MMPバッファーで抗体を20nMに希釈し、50nMになるよう上記プロテアーゼをそれぞれ添加し、37℃で反応後、ヒトTROP2抗原の固定されたウェルに添加した。
細胞内プロテアーゼであるCAPNの基質配列と、細胞外プロテアーゼであるuPAの基質配列を組合せることで、uPA基質のみを搭載した場合と比較して、マスク抗体の結合活性を向上させられるか検証することを目的に、uPA基質のみを搭載したMHT3423(表1、図41、配列番号16)、CAPN基質のみを搭載したMHT3201、uPAとCAPN基質の両方を搭載したMHT3202および、公知のuPA基質の部分配列(Journal of Biological Chemistry.;272(33):20456-20462(1997).)とCAPN基質の両方を搭載したMHT3203(表1、図42、配列番号17)を設計した。実施例1)-1と同様の方法で各抗体を調製し、以下に記載する部分を除き、実施例4と同様の方法でプロテアーゼ添加条件、非添加条件におけるヒトTROP2抗原に対する結合活性をELISAで評価した。プロテアーゼ添加条件では、MMPバッファーで抗体を2000nMに希釈後、200nMのuPAまたはCAPN1を添加し、37℃で反応後、MMPバッファーで濃度調整した抗体をヒトTROP2抗原の固定されたウェルに添加した。プロテアーゼ非添加条件でも同様に、MMPバッファーで調製した抗体を各ウェルに添加した。
