Description
本発明のモノクローナルタウ抗体を構築するときに化学的および物理的安定性と関連する重大な問題に直面した。直面した問題には、低い結合親和性、免疫原性、凝集、HC二量化、ならびに可変領域脱アミド、酸化、異性化およびミスフォールディングが含まれた。
本発明の改変されたタウモノクローナル抗体は、本質的に以下の通りに発現させ精製してよい。配列番号11のDNA配列(配列番号1のLCアミノ酸配列をコードする)および配列番号12のDNA配列(配列番号2のHCアミノ酸配列をコードする)を含有するグルタミンシンセターゼ(GS)発現ベクターを、電気穿孔法によってチャイニーズハムスター卵巣細胞株(CHO)をトランスフェクトするために用いる。発現ベクターは、SV早期(シミアンウイルス40E)プロモーターおよびGSのための遺伝子をコードする。GSの発現は、CHO細胞によって必要とされるアミノ酸、グルタミンの生化学的合成を可能にする。トランスフェクト後、細胞は、50μMのL−メチオニンスルホキシイミン(MSX)を用いるバルク選択(bulk selection)を受ける。MSXによるGSの阻害を、選択の厳重さを増加するために利用する。宿主細胞ゲノムの転写活性領域への発現ベクターcDNAの組み込みを有する細胞は、内因性レベルのGSを発現する、CHO野生型細胞に対抗して選択され得る。トランスフェクトしたプールを、低密度で平板培養して安定発現細胞のクローン性に近い増殖(close−to−clonal outgrowth)を可能にさせる。マスターウェルを、抗体発現についてスクリーニングし次いで産生に用いるために血清を含まない、懸濁培養液中で拡大する。抗体がその中へ分泌されている、浄化した培地を、リン酸緩衝食塩水(pH7.4)などの適合した緩衝液で平衡化したプロテインA親和性カラムに適用する。カラムを、非特異的な結合成分を除去するために1M NaClで洗う。結合したタウモノクローナル抗体を、例えば、クエン酸ナトリウムでpH(約)3.5で溶離して画分を1M Tris緩衝液で中和する。タウモノクローナル抗体画分を、SDS−PAGEまたは分析用サイズ排除などによって、検出し次いでプールする。可溶性凝集体およびマルチマーは、サイズ排除、疎水性相互作用、イオン交換、またはヒドロキシアパタイトクロマトグラフィーを含めた、一般的な技術によって有効に除去してよい。本発明のタウモノクローナル抗体を、一般的な技術を用いて濃縮および/または除菌ろ過する。これらのクロマトグラフィーステップ後のタウモノクローナル抗体の純度は、95%より大きい。本発明のタウモノクローナル抗体は、−70℃で直ちに凍結または数か月間4℃で貯蔵してよい。
BIACORE(登録商標)2000計器(HBS−EP+ランニング緩衝液(GE Healthcare、10mM Hepes pH7.4+150mM NaCl+3mM EDTA+0.05%界面活性剤P20)で25℃で準備)で測定する、表面プラズモン共鳴(SPR)アッセイを、実施例1の例示したタウモノクローナル抗体のヒト単量体(例えば、未変性または非凝集性)タウおよびヒトタウ凝集体(共に配列番号13に記述されているようなアミノ酸配列を有する)の両方への結合を測定するために用いる。ヒト化MC−1抗体構築物(フレームワークの組み合わせ:5−51重鎖、A27軽鎖を有する)のヒト単量体タウおよびヒトタウ凝集体への結合を、同一の手法で測定する。
例示した実施例1のタウモノクローナル抗体のヒト脳由来の凝集性タウへの結合を、「正常な」個人(最少のタウ凝集を示している)、AD患者(重篤なタウ凝集およびNFT形成、ならびにアミロイド斑病変を示している)、PD患者(重篤なタウ凝集を示している)から得られるホルマリン固定パラフィン包埋(FFPE)脳切片の免疫組織化学染色によって決定する。染色は、バックグラウンドの非特異的な染色レベルを決定するためにヒトタウを有さない「対照」野生マウス由来の脳切片でも実行する。
約5か月齢のP301Sマウスからのホモジネート脳調製物は、未変性の、非凝集体タウの存在下で、未変性タウの凝集を誘導するためおよびタウ凝集の伝播様効果を実証するために、知られている。4.5から5か月齢のP301Sマウスからの脳組織のサルコシル不溶性ホモジネート調製物を、超音波処理してOPTI−MEM(Life Tech.によるGIBCO、製品番号31985−062)で希釈して0.77μg/mlの最終濃度までの測定されたタウ(1調製物当り)をもたらす。それぞれの調製物を、例示した実施例1のタウモノクローナル抗体(濃度:21.00、7.00、2.33、0.78、0.26、0.09、0.03、および0.01μg/ml)またはヒト化MC−1抗体構築物(濃度:50.00、16.67、5.56、1.85、0.62、0.21、0.07、0.02および0.01μg/ml)のうちの1つと共に室温で30分間インキュベートする。
約5か月齢のP301Sマウスからのホモジネート脳幹調製物は、正常な10週齢の雌P301Sマウスの海馬内への注入で、タウ凝集の伝播様効果を実証する、未変性、非凝集体タウの凝集を誘導することが知られている。4.5から5か月齢のP301Sマウスからの脳幹組織のホモジネート調製物を、実質的に上述と同様に調製する。
遺伝子導入Tg4510マウスは、ヒトタウの突然変異形態を発現する(残基301(P301L)におけるプロリンについてロイシン置換を有する、4R0N、Ramsden M.ら、J.Neuroscience.、25:10637〜10647(2005年)およびSantacruz K.ら、Science(2005年)、例示した配列番号13のヒトタウに基づく残基番号付け)。Tg4510マウスは、海馬および新皮質領域においてP301L突然変異体ヒトタウの高レベルの発現を示し、これは、年齢依存性のタウ凝集進行を実証する。
例示した実施例1のタウモノクローナル抗体は、良好な溶解度、化学安定性、および物理的安定性を実証する。
十分に高い溶解度は、好都合な投薬を可能にするために望ましい。例えば、100kgの患者への1.0mLの注入によって投与される1mg/kgの投与量には、100mg/mlの溶解度が必要となる。さらに、高濃度において高分子量(HMW)の凝集を伴わず抗体を単量体状態に維持することも、望ましい。例示した実施例1のタウモノクローナル抗体の溶解度を、15mgの例示した抗体を10K分子量カットオフフィルタ(Amicon U.C.filters、Millipore、カタログ番号UFC903024)で100μl未満の体積に濃縮することによって解析する。試料の最終濃度を、Nanodrop 2000(Thermo Scientific)を用いてA280におけるUV吸光度によって測定した。
化学安定性は、十分な貯蔵寿命を有する薬剤製剤の開発を容易にする。例示した実施例1のタウモノクローナル抗体の化学安定性を、例示したタウ抗体を10mMクエン酸中に1mg/mlの濃度に製剤することによって評価してpH4、5、6、または7に緩衝化する。製剤した試料を、加速分解調査において4℃、25℃、または40℃で4週間インキュベートする。化学変化を示す、抗体の電荷プロファイルにおける変化を、毛管等電点電気泳動(cIEF)を用いて標準的な手順に従って評価する。
