Description
本出願は、その全体で参照により本明細書に組み込む、2016年10月26日に出願された米国仮特許出願第62/413,013号の優先権の利益を主張するものである。
以下の定義及び方法は、本開示をより良く定義し、本開示の実施において当業者を導くために提供される。特に断りのない限り、用語は、関連技術分野における当業者による慣用法に従って理解されるものとする。
本明細書に記載される方法は、セルロース含有フィルタ材料をカーボネート含有溶液で処理する工程を伴う。一般に、フィルタ材料の処理は、ソーキング、循環、再循環、洗浄、フラッシング、通過、又はそうでなければ、以下にさらに詳細に検討されるとおりに、フィルタ材料を溶液と接触させて、それから浸出性ベータ-グルカンを除去する工程によって行われる。
一般に、本明細書に記載される浸出性ベータ-グルカンを除去するための本明細書に記載される方法は、ベータ-グルカンを所望の生成物中に浸出させるリスクを課し得る、任意のセルロース含有濾過若しくは固体支持材料、媒体又はメンブレンとともに用いられてもよい。本明細書にさらに詳細に記載されるとおり、処理は、濾過デバイス(例えば、フィルタ材料のハウジングを含む)の形成前又は後に、濾過デバイスの形成前及び後の両方で、所望の生成物の濾過前に(すなわち、前処理として)、並びにそれらの組み合わせ及び倍数で行われ得る。したがって、本開示の別の態様は、本明細書に記載される方法によって処理されたセルロース含有フィルタ材料であって、未処理フィルタ材料と比較される場合に減少した量の浸出性ベータ-グルカンを有する、フィルタ材料である。
上で留意されたとおりに、セルロース含有培地及びフィルタは、標的分子からの不純物の除去のためにバイオ医薬及び血漿精製プロセスで広く使用されている。したがって、本開示の別の態様は、減少した量の浸出ベータ-グルカンを有するバイオ医薬又は血漿誘導体を調製する方法であって、いずれか先行する処理特許請求の方法によって処理されたセルロース含有フィルタ材料との接触によって、バイオ医薬又は血漿誘導体を処理する工程を含む、方法である。本開示のさらに別の態様は、上述の方法によって調製されたバイオ医薬又は血漿誘導体である。
[実施例1]:デプス濾過媒体からのベータ-グルカンの除去のための異なるフラッシング化学の調査
この実施例では、5つの特殊フラッシング化学をセルロース系デプス媒体からのベータ-グルカンの除去について試験した。調査された化学は、2M塩化ナトリウム、4M尿素、1M炭酸ナトリウム緩衝液pH10、0.5N水酸化ナトリウム及びRODI水(Milli Q)を含んだ。溶液を調製し、使用前に滅菌濾過した。実験は、5cm2メンブレン面積を有するViresolve Pre Filter(VPF)マイクロデバイス(OptiScale 40 Capsule Cat No SSPVA40NB9)で行った。実験装置は、圧力降下及び流量データを収集するための自動データ収集システム(DAQ2.0)、白金硬化シリコンチュービングフローパス(Cat No#HV-96410-14、Cole Parmer、IL、USA)、単一使用圧力変換器(PDKT-104-03、Pendotech、NJ)を含んだ。4つのトレインを平行に組み立てた。実験装置の概略は、図1に示す。
1.カーボネート対イオンの効果
カーボネート対イオンの分析を行って、ベータ-グルカン除去のためのフラッシング溶液としてのその利用性の操作上の実行可能性を評価した。分析のために選択された主要な基準は、毒性、溶解度及び他の操作上の関心事項であった。例示的な調査対イオンの要約を表2に与える。
実験の設計(DOE)は、pH、濃度及び静的保持時間についての有効範囲を特定するために行った。Box Behnken設計を研究のために選択した。パラメータ及び関連レベルのリストを表3に示す。
ベータ-グルカン=3154-908濃度-536.7pH+7.54静的保持時間+107.8濃度*濃度+23.84pH*pH-0.00854静的保持時間*静的保持時間+72.9濃度*pH+0.782濃度*静的保持時間-0.631pH*静的保持時間 (1)
測定に対する予測浸出ベータ-グルカン濃度のプロットを図8に示す。
この研究において、本発明者らは、フラッシングが実施例1並びに実施例2のセクション1及び2の場合におけるとおりのフロースルーモードと比較して再循環モードで行われ得るかどうか調査した。再循環モードは、GMP設定に設置されるデプスフィルタでフラッシュを行うために必要とされる溶液体積を減少させるのに役立ち得る。
この実施例において、フィルタ媒体を作製するために使用されたセルロールパルプからのベータ-グルカンの減少に対する炭酸カリウム及び炭酸ナトリウムの有効性を調査した。パルプは、平シートの形態で受けた。47mmのディスクを47mmArch Punchを使用して打ち抜いた。ディスクをMillipore CorporationステンレススチールフィルタホルダCAT NoXX4404700内に設置した。1つのディスクを各ホルダに設置した。4つの並行濾過トレインを、実施例1及び実施例2に同様な圧力及び流量データを収集するための自動データ取得システムを使用して組み立てた。0.5M炭酸ナトリウムpH10及び0.5M炭酸カリウムpH10、0.5N水酸化ナトリウムをこの研究中に試験した。水を負対照として使用した。
