CEA CD3二重特異性抗体CEA TCBを、組み換えタンパク質の生成から一般的に知られている技術により製造した。これら実施例に従って製剤を調製するために、CEA TCB抗体は、20mMのヒスチジンバッファー(L-ヒスチジン/HClバッファー)中、約5.5のpHにおいて、標的濃度を約20-30%上回る濃度で提供される。
液体製剤の調製のために、CEA TCBを、予期されるバッファー組成物を含むダイアフィルトレーションバッファーに対してバッファー交換し、必要であればダイアフィルトレーションにより標的濃度を約20-30%上回る抗体濃度に濃縮した。ダイアフィルトレーション工程の完了後、添加剤(例えばスクロース、塩化ナトリウム、メチオニン)を保存溶液として抗体溶液に加えた。次いで界面活性剤を、50から200倍の保存溶液として加えた。最後に、バッファーを用いてタンパク質濃度を最終的なCEA TCB濃度が約5mg/ml又は約20mg/ml又は約50mg/mlとなるように調節した。
1)UV分光測光;
2)サイズ排除クロマトグラフィー(SEC);
3)イオン交換クロマトグラフィー(IEC);
4)溶液の混濁度の測定;
5)可視粒子の検査。
製剤Aは、50mg/mlのCEA TCB、20mMのL-ヒスチジン(pH5.5)、230mMのスクロース、0.05%のポリソルベート20、10mMのメチオニンという組成を有する液体製剤である。
