Description
本発明の1の実施態様において、4リットルの酢酸バッファーを調製した。この実施態様において、最終バッファーは、50mM酢酸ナトリウム、0.05mM EDTA、51mM NaCl、1.0%アルギニン、0.02%ポリソルベート80、pH5.5から成っていた。酢酸ナトリウム三水和物、エデト酸二ナトリウム(EDTA)、ポリソルベート80およびL−アルギニン遊離塩基を3.5Lの脱イオン水に溶解することによってバッファーを調製した。pHを3N HClを用いて5.5に調製したらすぐに、容量を4.0Lまで引き上げ、バッファーを0.45μmフィルターユニットを用いて濾過した。次いで、使用するまでバッファーを2〜8℃にて保存しうる。本願に記載の「%」なる語句は、「容量%」を示す。
本発明の1の実施態様において、オファツムマブを、プラットフォーム処方(50mM酢酸ナトリウム、51mM NaCl、0.05mM EDTA、0.02%ポリソルベート80、および1.0%アルギニン(遊離塩基))に透析濾過し(diafiltrated)、安定にするために濃縮した。オファツムマブを、3種の膜を伴うラボスケールタンジェンシャルフローシステム(lab-scale tangential flow system)を用いてプラットフォーム処方に透析濾過した。プラットフォームバッファーに透析濾過した後、オファツムマブを179mg/mLの最大濃度に濃縮した。全てのプロセルを終えるのに操作時間は約3日かかり、収率は96.1%であった。約20−179mg/mLの濃度範囲を研究できるように、179mg/mLの一部をプラットフォーム処方バッファーで希釈した。
12週間以上の外観の直接比較および振盪実験のために、抗CD20抗体(オファツムマブ)を20mg/mLの濃度で標準処方およびプラットフォーム(本発明の1の実施態様)処方中に調製した。
標準およびプラットフォーム処方の抗CD20抗体を、低タンパク質結合0.2μm膜フィルターを用いて濾過した。濾過後、きれいなドラフト中で無菌操作を用いて各処方を5ccバイアル中に3mL充填し、栓をし、圧着した。各処方の2つのバイアルを、温度調節して振盪機上に置いた。バイアルを、55℃の温度にて325rpmで振盪した。加熱振盪している間、42時間にわたって一定時間ごとに、実施例3.2に記載するように、外観を観察した。図1および2は、それぞれ、加熱振盪の18.5時間後の、標準およびプラットフォーム処方を示す。振盪研究の全体の外観結果は、プラットフォームより急速に55℃の温度にて振盪させる場合に、標準処方が時間とともに粒子を生成するであろうことを示した。
抗CD20モノクローナル抗体の振盪研究サンプルの外観(GA)を以下の表に示す。色、透明度および可視粒子状物質を記載するIgG抗体溶液に用いられうる一般法を用いてGAを達成した。
DSCによる試験を適正に終了するために、バッファー単独およびタンパク質とのスキャンを得た。標準およびプラットフォーム処方中のタンパク質を、実施例4.1に示すように1mg/mLに希釈した。各スキャン前に15分平衡化して70℃/時間の走査速度で5〜80℃スキャンするようにDSCを設定してデータを得た。DSCサンプル細胞の容量は、約0.5mLであった。バッファーおよびタンパク質のスキャンを得た後、次いで、バッファースキャンをタンパク質スキャンから差し引くことができた。サンプル中のタンパク質濃度を、各スキャン中の濃度を補正するために得た(実施例4.2を参照)。Tunの値、℃、変性の開始、Tm、℃、(転移最大値での) 変性温度およびT1/2、℃、半分の高さでのピーク幅(転移の三次構造および共同性の変化を示す)を、各処方のオファツムマブについて得た(実施例4.3を参照)。実際のDSCスキャンは図3にて見ることができる。DSCの結果に基づき、標準処方中またはプラットフォーム処方中のいずれかのオファツムマブは、類似のDSCプロファイルを有しているため、類似の熱安定性を有することが期待されるであろう。
