Abstract
Description
配列番号1は、1E4重鎖可変ドメインのアミノ酸配列である。
以下、本発明の多様な態様に関して詳細に説明する。しかしながら、このような態様は多い他の形態に具体化されることができ、以下に説明された実施例に限定されるものとして解釈されるものではない。以下の実施例は本発明が完壁になされることができるように当業者にその範囲を伝達する。
本明細書で使われる単数形態“a”、“an”、及び“the”は文脈上、明確に異なる指示がない限り、複数(plural)対象を含む。したがって、例えば、“重合体”に対する言及は1つ以上の重合体だけでなく、2種以上の同一または相異する重合体を含み、“賦形剤(excipient)”は1つ以上の賦形剤だけでなく、2種以上の同一または相異する賦形剤を含む。
A.治療ターゲットとしてのc−Met
肝細胞成長因子(hepatocyte growth factor、HGF)受容体とも知られたc−Met受容体タンパク質は肝、膵臓、前立腺、腎臓、筋肉、及び骨髄を含む多い器官の上皮細胞表面で発現される。c−Metに対するリガンドはHGFである。HGFは身体の多様な組織で細胞増殖、生存、運動性、散乱(scattering)、分化、及び形態形成(morphogenesis)を促進させる発達因子(pleiotropic factor)及びサイトカインとして作用する。また、HGFは肝硬化、肺線維症、及び進行性腎臓病症のようないろいろな疾病で保護的な役割をすると見える。HGFがc−Metの細胞外ドメインに結合すれば、c−Metの細胞質ドメイン内の多重チロシン残基がリン酸化される。Y1234及びY1235のリン酸化はc−Metチロシンキナーゼ活性及び、続いて表れるY1349及びY1356残基のリン酸化を活性化させる(Matsumoto et al., 2014, Biomedicines, 2:275−300)。リン酸化されたチロシン残基は多様な細胞内信号分子を募集して細胞分裂及び移動の促進、細胞死滅の抑制、及び上皮細胞の形態形成誘導のような生物学的活性を示す。HGF−c−Met相互作用は肝、腎臓、皮膚、膵臓、肺、神経系、心臓、及び免疫体系など、多様な生物学的システムで表れて、これに限定されるものではない。
c−Metタンパク質に結合する免疫グロブリンはPCT出願第PCT/KR2015/007899号に記載されている(その内容は全体が参考文献として引用される)。要約すると、バイオパンニング(biopanning)のための完全ヒト化(fully humanized)単一鎖抗体(scFv)ファージディスプレイライブラリー(phage display library)を使用して、ヒトc−Metに結合するscFv種を選択した。本願で“1E4”scFvと称されるscFvはc−Metと高い親和度として結合することが立証されており、本願で配列番号3として提示されたアミノ酸配列を有する。1E4 scFvまたはその変異体は以下でより詳細に記述されるように、これを必要とする対象の治療に使用できる。
(1)疏水性(hydrophobic):ノルロイシン(Norleucine)、Met、Ala、Val、Leu、Ile;
(2)中性親水性(neutral hydrophilic):Cys、Ser、Thr、Asn、Gln;
(3)酸性(acidic):Asp、Glu;
(4)塩基性(basic):His、Lys、Arg;
(5)鎖配向に影響を及ぼす残基:Gly、Pro;
(6)芳香族(aromatic):Trp、Tyr、Phe。
scFvコンストラクト(配列番号3)の重鎖及び軽鎖可変ドメインからの全長ヒト1E4 IgG抗体の生成は、一般的な方法及び組成物を使用して遂行される。本明細書に記載された方法に使われるヒト1E4抗体の製造方法は、以下の実施例1及び第PCT/KR2015/007899号に記載されている。本明細書に記載されたような1E4抗体の可変ドメインをコーディングする核酸(配列番号11及び12、及びこれらの変異体)は、一般的な方法を使用して全長抗体を生成することに使用できる。一部の具現例で、本発明の抗−c−Met抗体の重鎖をコーディングする核酸は、任意の供給源からの重鎖不変ドメインをコーディングするヌクレオシド配列にイン−フレーム(in−frame)接合された、本発明のVHドメインをコーディングするニュークレオタイド配列(配列番号11)を含むことができる。類似するように、本発明の抗−c−Met抗体の軽鎖をコーディングする核酸分子は、任意の供給源からの軽鎖不変ドメインをコーディングするヌクレオシド配列にイン−フレーム接合された、本発明のVLドメインをコーディングするニュークレオタイド配列(配列番号12)を含むことができる。
本発明の一態様は、1E4抗体の重鎖及び軽鎖可変ドメインを含むポリペプチドの治療学的有効量をこれを必要とする対象体(subject)に投与するステップを含む、傷治癒を促進する方法に関するものである。以下の実施例2に記載されたように、1E4抗体をマウス傷に投与すれば、1E4抗体を投与しないマウスの傷治癒と比較して傷治療が速くなる。図1に図示したように、3μg、6μg、または12μgの1E4抗体をマウス皮膚傷に局所投与した場合、1E4免疫グロブリンを投与しない場合と比較して創傷面積を少なくとも20%減少させることに効果的であった。当業者は1E4のc−Met結合ドメインを含む免疫グロブリン分子の投与が対象体で傷治癒を促進することに効果的であることが分かる。
本発明の一態様は、前述した1E4抗体の可変ドメインを含むポリペプチドをこれを必要とする対象体(subject)に投与するステップを含む、腎臓組織に対する損傷を予防または治療する方法に関するものである。以下の実施例3では動物に対する1E4抗体の投与が化学療法薬物であるアドリアマイシン(adriamycin、ADR)の動物に投与することによって引起こされる腎臓組織損傷を減少させることを示す。具体的に、BALB/cマウスに2mg/kg、5mg/kg、または10mg/kgの1E4抗体を尻尾静脈投与した。翌日、15mg/kgのADRの単一尻尾注入により腎臓損傷を誘導した。その後、マウスに2mg/kg、5mg/kg、または10mg/kgの1E4抗体をADR注射後、2日及び5日目に静脈内注射した。図2A及び図2Bから見ることができるように、1E4免疫グロブリン5mg/kgまたはその以上の容量はBUN(血液尿素窒素)及びクレアチニン増加を減らすことに効果的である。血液でのBUN及びクレアチニン水準の増加は腎臓の機能喪失及び損傷の指標である。腎臓機能が低下することによってクレアチニンと尿素(糸球体濾過に大きく依存する)の血漿濃度は非線形上昇を始める。初期にはクレアチニン及びウレア濃度の変化がほとんどない。以後、クレアチニン及びウレア濃度水準は急速に増加し、一般的に全身徴候(systemic manifestations)と関連する。
本発明の一態様は、前述した1E4抗体の可変ドメインを含むポリペプチドをこれを必要とする対象体(subject)に投与するステップを含む、組織に対する虚血性損傷を予防または治療する方法に関するものである。1E4抗体は動物モデルで虚血性脳卒中による損傷を減少させることに効果的であると表れた(実施例5参照)。1日前10mg/kgの1E4抗体を投与したラットで中大脳動脈を閉塞させた動物モデルを使用した。閉塞の以後、3、10、17、及び24日目にラットに10mg/kgの1E4抗体を静脈内投与した。脳組織の分析はMRIを使用し、硬塞の程度を測定した。1E4抗体投与が閉塞モデルで硬塞大きさを減少させることに効果的であることと表れた(図5参照)。
本発明の一態様は、前述した1E4抗体の可変ドメインを含むポリペプチドをこれを必要とする対象体(subject)に投与するステップを含む、網膜で病理学的血管新生(pathologic neovascularization)と関連した新生血管網膜疾患(neovascular retinal disease)を予防または治療する方法に関するものである。以下の実施例6は、動物モデルで病理学的新生血管形成の成功的な治療を示す。特に、視神経の周囲に光凝固斑点が生じたチンチラ(Chinchilla)うさぎにレーザー誘導脈絡膜新生血管モデル(choroidal neovascularization、CNV)を適用した。うさぎに50μgの1E4抗体を硝子体液(vitreous humor)に直接投与すれば、レーザー誘導成CNV形成が抑制されて(図6参照)、治療を必要とする対象体を1E4免疫グロブリン組成物で網膜の病的新生血管形成を予防または治療する実施態様を裏付ける。
本発明の一態様は、前述した1E4抗体の可変ドメインを含むポリペプチドをこれを必要とする対象体(subject)に投与するステップを含む、神経疾患または障害を予防または治療する方法に関するものである。HGFの結合によるc−Metの活性化は神経系の発達及び維持に重要な役割をする。c−Metは反応性星状細胞(reactive astrocytes)、希突起膠細胞前駆細胞(oligodendrocyte progenitors)、稀突起膠細胞(oligodendrocytes)、及び微膠細胞(microglia)のような非−神経細胞だけでなく、大脳皮質(cerebral cortex)、海馬(hippocampus)、小脳(cerebellum)、脳幹運動神経核(brainstem motor nucleus)、網膜及び感覚神経節(retina and sensory ganglia)、及び脊髄(spinal cord)を含んだ成熟した脳及び発達する脳で発現される(Funakoshi and Nakamura、2011、Current Signal Transduc Ther, 6:156−167)。
本発明の他の態様は、抗体またはそのコンジュゲート(conjugate)及び薬剤学的に許容可能な担体(carrier)を含む薬剤学的組成物に関するものである。
1E4 c−Met抗体を投与するための効果的な投与量及びスケジュールは経験的に決定されることができ、そのような決定を下すことは当業界の技術範囲内にある。当該技術分野の熟練した技術者は投与される薬剤の投与量が薬剤を投与する対象、投与経路、使われた特定類型の薬物及び対象に投与される他の薬剤によって変わることを理解することができる。例えば、抗体の適切な投与量を選定する指針は“Handbook of Monoclonal Antibodies, Ferrone et al., eds., Noges Publications, Park Ridge, N.J., (1985) ch. 22 and pp. 303−357; Smith et al., Antibodies in Human Diagnosis and Therapy, Haber et al., eds., Raven Press, New York (1977) pp. 365−389”の抗体の治療用途に関する文献に記載されている。単独で使われる薬剤の典型的な投与量は前述した要因によって、体重に対し、または一日当たり約0.01mg/kg乃至500mg/kg体重であるか、約0.01mg/kg乃至約50mg/kg、または0.1mg/kg乃至約50mg/kg、または約0.1mg/kg乃至約10mg/kg、または約0.1mg/kg乃至約5mg/kg、または約5mg/kg乃至約10mg/kgまたは約0.2mg/kg乃至約1mg/kgでありうる。
以下の実施例は例示的なものであり、本発明の範囲を制限するものではない。
c−Met抗体の製造
以下の実施例で使われた1E4 IgG1抗体はHEK−293T細胞でリコンビナント発現により生成された。全長1E4抗体重鎖をコーディングする核酸を含むようにpIgGHDベクター(Aprogen、South Korea)を製造した。全長1E4抗体軽鎖をコーディングする核酸を含むようにpIgGLDベクター(Aproge、South Korea)を製造した。1E4抗体の重鎖及び軽鎖可変ドメインをコーディングする核酸は、ファージディスプレイライブラリーのバイオパンニング(biopanning)により生成されたScFvポリペプチドから得た。このような1E4重鎖及び軽鎖可変ドメインの生成はPCT出願番号PCT/KR2015/007899に記載されており、その全体内容は本出願の参考として引用された。1E4軽鎖可変ドメインは配列番号2と表示されるアミノ酸配列を有し、1E4重鎖可変ドメインは配列番号1と表示されるアミノ酸配列を有する。1E4軽鎖可変ドメインをコーディングする核酸をSfiIエンドヌクレアーゼで処理したpIgGLDベクターに挿入し、1E4重鎖可変ドメインをコーディングする核酸をSfiIエンドヌクレアーゼで処理したpIgGHDベクターに挿入した。以下の実施例に使われた全長1E4抗体をリコンビナント発現させ、pIgGHDベクターをSfiIエンドヌクレアーゼで処理し、pIgGLDベクターをBstXIエンドヌクレアーゼで処理した。1E4 IgG抗体を生産するために、HEK−293T細胞を同量の軽鎖及び重鎖発現ベクターで形質感染させた。

動物で1E4抗体の傷治癒促進効果を実験した。無菌状態でマウス(Balb/C、8週齢雌性)を麻酔させた。背の毛を除去した後、6mm生検パンチ(Integra Miltex、cat # 11L48)を使用してマウスの背の皮膚の両側に6mm円形傷を作った。傷の元の形態を保存し、試験物質の傷治癒効果をより正確に測定するために、創傷副木(内径7mm、Grace Bio−Labs、Cat # 1213138)で傷部位を接着及び封入した(Galiano et al., Wound Repair Regen Jul−Aug, 12(4):485−92, 2004; Li et al., J Diabetes Res 2015:512959, 2015)。マイクロピペットを使用してPBS(対照群)または1E4 20μlを傷部位に各々異なる容量(傷当たり1日3μg、6μg、または12μg)で均等に塗布した。傷部位を保護するために傷部位をTegaDerm(3M、Cat # 2016−07PK)で覆った。PBSまたは1E4を14日間毎日投与した。傷縫合の経過を分析するために2−3日毎にイメージを撮影した。
抗c−Metアゴニスト抗体の腎臓保護効果
多い研究から分かるように、抗癌治療剤アドリアマイシン(adriamycin、ADR)は腎臓毒性があり、マウスに投与した時、腎臓内損傷により血中尿素窒素(BUN)及びクレアチニンが全て増加することと報告された(Rossmann et al. J Pathol. 169 (1):99−108, 1993; Wang et al.; Kidney Int. 58(4):1797−1804, 2000; Okuda et al Kidney Int 29, 502−510, 1986.)。化学療法により発生する損傷から腎臓を保護するアゴニスト抗c−Met抗体の能力を実験した。
抗c−Metアゴニスト抗体の抗−線維化効果
一側性尿管閉鎖(Unilateral ureteral obstruction、UUO)は腎臓線維症としてよく知られており、慢性腎臓疾患の病理学的特徴を示す(Klahr et al., Am Physiological Soc, Vol.283, No.5, F861−F875, 2002; Klahr et. al Nephrology Forum, Kidney Int 54: 286−300, 1998)。したがって、この動物モデルを使用して腎臓の線維性病変にアゴニスト効果を示す抗c−Met抗体の効果を研究した。
抗c−Metアゴニスト抗体を用いた脳卒中治療
中間大脳動脈閉塞モデル(middle cerebral artery occlusion model、MCAO)は脳卒中研究分野で広く用いられるモデルである。このモデルは虚血性脳卒中の根本的なメカニズムと疾病を治療するための試験物質または薬物の治療効果を調べるための立派な道具として使われる(Badr et al., Am Physiological Soc, Vol.280 no.3 : R766−R770, 2001; Zhao et al., Blood, 114 (15) : 3329−3334, 2009)。虚血性脳卒中または他の虚血関連疾患による組織損傷を最小化するための、抗c−Metアゴニスト抗体1E4の効果を試験した。
抗c−Metアゴニスト抗体を用いた新生血管網膜疾患の治療
レーザー−誘導された脈絡膜新生血管(choroidal neovascularization、CNV)モデルは網膜での病原性血管新生に対する薬物の治療効果を調べることができる優れるプラットフォームを提供する(Marano et al. Gene Therapy, 12, 1544−1550, 2005; Zhan et al. Arch Ophthalmol, Oct; 127 (10): 1329−35, 2009)。CNVモデルは網膜血管新生に対する抗c−Metアゴニスト抗体の効果を研究することに使われた。
抗c−Metアゴニスト抗体を用いた神経疾患の治療
シュワン細胞(Schwann cells)は神経発達、伝導(髄鞘形成を通じての)及び再生のような神経系の多様な側面で重要な役割をすることと知られている。病理学的条件下で、シュワン細胞は損傷された神経を再−ミエリン化(re−myelinate)させるために移動する(Whalley Katherine, 2014, Nat Rev Neurosci., 15 (11) : 698−99, 2014; Jessen KR et al., 2015, Cold Spring Harb Perspect Biol. 7 (7): a020487, 2015)。シュワン細胞移動に対する抗−c−Met抗体1E4の影響を調べるために、10%ウシ胎児血清(FBS)、グルタミン、ペニシリン/ストレプトマイシン、及びHEPESを添加したDulbecco’s modified eagle’s mediumを含有する完全培地でラットシュワン細胞(Rat Schwann cells、iSC)を培養した。移動分析のために、Transwell(Corning、3422)挿入物を細胞培養器(37℃及び5% CO2)で45分間0.1%ゼラチン(Sigma、G1393)でコーティングした。ラットシュワン細胞を0.25%トリプシン−EDTAで処理後、Transwellシステムの上部区画に100μlの完全培地に細胞を分注した。下部チャンバーは2%FBSが含まれた600μlの完全成長培地で詰められた。Transwellシステムを37℃、5%のCO2で50分間培養して細胞が鎮まるようにした。結果的に、下部チャンバーの成長培地には次の通り50ng/mlリコンビナントヒトHGF(R&D systems, 294−HGF−025/CF)または多様な濃度の1E4が補充された:900ng/ml、450ng/ml、90ng/ml、及び18ng/ml。Transwellフィルタを通じての細胞移動を4時間の間進行させた。Transwell挿入物(inserts)にある細胞を4%ホルムアルデヒドで一日間4℃で固定させた。固定後、細胞を0.2%クリスタルバイオレットで染色し、フィルタ上端の移動しない細胞を綿棒で除去した。Olympus顕微鏡を使用して5個のイメージを撮影し、フィルタを移動した細胞の数を計算し、平均を求めた。
抗c−Metアゴニスト抗体を用いた筋萎縮性側索硬化症の治療
ヒト突然変異SOD1を発現するB6SJL−Tg(SOD1−G93A)マウスは、ALS(Amyotrophic lateral sclerosis)及び他の神経筋肉障害治療剤の治療効能を評価するための形質転換動物モデルである(Ji−Seon Seo et al., Exp Neurobiol., Dec; 24 (4) : 341−350, 2015; Gurney ME et al., Science., 264 : 1772−1775, 1994)及び他の神経筋肉障害。したがって、このモデル動物でALS症状の発病に対する1E4抗体投与の効果を試験した。Rotarodの行動評価方法を基準に、マウスをグループ別に分けた。
