Description
KINEVAC(登録商標)は1976年に初めて導入され、完成品は、5mL(公称)ガラスバイアル入りの滅菌済み非発熱性の凍結乾燥白粉で、張度を与えるために45mg塩化ナトリウムを加えた、5μgのシンカリドを含有し、さらに、pH調整用(pH5.5〜6.5)に、水酸化ナトリウムあるいは塩酸が加えられることもある。このI型ガラスバイアルを、ヘッドスペースに窒素を充填して、トンプキンスB0849栓(TompkinsB0849 Closure)で密封される。この二成分製剤は、米国薬局方国民医薬品集、USP24、NF19、2000年1月1日に記載されている。
米国薬局方国民医薬品集、USP24、NF19、2000年1月1日
製薬業で製造される製剤には、賦形剤不純物および/または栓からの溶性物のために、微量金属が混入することがある。シンカリドは、遊離金属により酸化されやすい二種のメチオニン残基(Met3およびMet6)を含む。従って、本発明のシンカリド製剤は、シンカリド中に存在する二種のメチオニン残基(Met3およびMet6)の酸化を阻害するためのキレート剤を含む。好ましいキレート剤として、ペンテト酸(DTPA)とエデト酸(EDTA)、およびその塩を含む誘導体などが挙げられる。DTPAは好ましいキレート剤である。下記の実施例2で説明するように、劣化量、つまりシンカリドMet3およびシンカリドMet6モノスルホキシドの量は、一定の金属の存在下およびDTPAの非存在下において増加するが、一方、DTPAの存在は、これらのモノスルホキシドの形成に対する阻害効果を有する。DTPAの非存在下では、特に、銅やマンガンが、シンカリドのメチオニン残基に対し最も強い酸化効果を示し、その結果、Met3およびMet6モノスルホキシドの結合(対シンカリド)が、それぞれ85.5%および128.9%という高い割合で生ずる。
本発明のシンカリド製剤のpHを安定させ、ひいては極度のpH値において化学的に不安定になる可能性を減少させるために、緩衝剤を採用する。本発明の製剤キットの調製において有用な緩衝剤として、これらに限定はされないが、リン酸、リン酸塩(例えば、リン酸二水素ナトリウム、リン酸水素二ナトリウム、リン酸二水素カリウム、リン酸水素二カリウム等)、クエン酸、クエン酸塩(例えば、クエン酸ナトリウム等)、スルホサリチル酸、酢酸、酢酸塩(例えば、酢酸カリウム、酢酸ナトリウム等)、ボロン酸メチル、ボロン酸塩、コハク酸二ナトリウム六水和物、アミノ酸塩(ヒスチジン、グリシン、リジン、イミダゾ−ル等)を含むアミノ酸、乳酸、乳酸塩(例えば、乳酸ナトリウム等)、マレイン酸、マレイン酸塩、塩化カリウム、安息香酸、安息香酸ナトリウム、炭酸、炭酸塩(例えば、炭酸ナトリウム等)、重炭酸塩(例えば、重炭酸ナトリウム等)、ホウ酸、ホウ酸ナトリウム、塩化ナトリウム、コハク酸、コハク酸塩(例えば、コハク酸ナトリウム)、酒石酸、酒石酸塩(例えば、酒石酸ナトリウム等)、トリス−(ヒドロキシメチル)アミノメタン、生物学的緩衝剤(N−2−ヒドロキシエチルピペラジン、N’−2−エタンスルホン酸(HEPES)、CHAPSおよびその他の「適切な緩衝液」)が挙げられる。
このオクタペプチド、すなわちシンカリドは、一つのトリプトファンと二つのメチオニン残基を含む。メチオニンは、最も容易に酸化されるアミノ酸の一つとして確認されており、相当するスルホキシド、さらに強い酸化条件下ではスルホンに劣化する。過酸化物基、ペルオキシルラジカル、一重項酸素、ヒドロキシルラジカルが、メチオニン残基をスルホキシドやその他の物質等に酸化することを考慮すると、この酸化メカニズムは活性酸素種にかなり依存していると考えられる。このため、このペプチドの酸化可能性に基づき、ペプチド安定化のための機能的な添加剤を同定する必要がある。
本発明では、各種の抗凍結剤/抗溶解剤を使用できる。好適な抗凍結剤は、凝固点を減少させ、および/またはガラス相に達するのに必要な冷却率を減少させるような水分子構造を有する。また、これらは、ガラス状態のガラス転移温度範囲も上げる。これらの抗凍結剤/抗溶解剤として、ジメチルスルホキシド(DMSO)、デキストラン、スクロース、1,2−プロパンジオール、グリシン、リジン、アルギニン、アスパラギン酸、ヒスチジン、プロリン等のアミノ酸/およびその塩、グリセロール、ソルビトール、塩化ナトリウム、フルクトース、トレハロース、ラフィノース、スタキオース、プロピレングリコール、2,3−ブタンジオール、ヒドロキシエチルデンプン、ポリビニルピロリドン(PVP)、PEGおよび同様の化合物、例えば、ヒト血清アルブミン、ウシ血清アルブミン、ウシガンマグロブリン、ゼラチン(あるいはPrionex等の誘導体)等のタンパク安定剤、デキストロース、グルコース、マルトース、アラビノース、ラクトース、イノシトール、ポリオール(ソルビトール、キシリトール、エリトリトール、グリセロール、エチレングリコール等)、テトラメチルグルコース、硫酸ナトリウム、シクロデキストリン、およびそれらの混合物が挙げられる、これらに限定されることはない。リジンおよびアルギニンは、好ましい抗凍結剤/抗溶解剤である。
ペプチドは、変性、凝集、沈殿、容器表面吸着、および/または撹拌により誘発された変性などにより物理的に劣化しやすい。ポリソルベートのような非イオン性界面活性剤を組成に加えることにより、界面張力を減少あるいは可溶化を補助するので、溶液中の製品の気液あるいは固液界面における変性や劣化を予防または減少を図れる。
本発明の製剤には、少量のシンカリドしか含まれないため、構造を与え、有効成分であるシンカリドを支持し、さらには等張化するために、充てん剤/等張化剤が有用である。本発明の凍結乾燥製品の調製において有用な充てん剤/等張化剤(凍結乾燥補助剤とも言う)は、当技術分野において公知であり、マンニトール、ラクトース、塩化カリウム、塩化ナトリウム、マルトース、スクロース、PEG類(例えば、PEG300、PEG400、PEG3350、PEG6000、PEG8000等)、トレハロース、ラフィノース、デキストロース、ポリガラクツロン酸、ガラクツロン酸、例えば、リジン、アルギニン、グリシン、ガラクトース等のアミノ酸類(アミノ酸塩を含む)、ヒドロキシプロピル−γ−シクロデキストリン(HP−γ−CD)といったシクロデキストリン、デキストラン、フィコール(Ficoll)、およびポリビニルピロリドン(PVP)があげられる。中でも、D−マンニトールは、本発明での使用に最も好ましい充てん剤/等張化剤である。
本発明の製剤において任意に使用できる他の賦形剤としては、防腐剤(例えば、塩化ベンザルコニウム)、浸透圧調節剤(例えば、デキストロース)、抗溶解剤(例えば、硫酸ナトリウム)、可溶化剤、等張化剤(例えば、塩化ナトリウム)、ケーキ形成剤、錯化剤、および溶解補助剤があげられる。非経口投与用のシンカリド製剤に使用される各種の賦形剤の一覧は、例えば、以下の文献に記載されている。“The Handbook of Pharmaceutical Additives”第2版、Michael & Irene Ash編;Easton, Pa.およびPollock等、“Remington's Pharmaceutical Sciences”,(第18版) 1990、A.

本発明のキットは、所定量のシンカリド、凍結乾燥補助剤または充てん剤/等張化剤、一つまたは複数の安定剤、界面活性剤、キレート剤、および緩衝剤からなる滅菌製剤を含む、一つあるいは複数のバイアルからなることが好ましい。この製剤組成の全てあるいは一部を含む、一つあるいは複数のバイアルは、独立して滅菌液あるいは凍結乾燥した固体の形状をとることができる。本発明の製剤キットの調製において有用な緩衝剤として、例えば、リン酸塩、クエン酸塩、スルホサリチル酸塩、酢酸塩、およびアミノ酸(アミノ酸塩を含む)を含む。リン酸水素二カリウムは、本発明のシンカリド製剤において好ましい緩衝剤である。このキットは、注射前に製剤を再構成するための、例えば、水や食塩水のような流体を含んでもよい。
シンカリドは、生体内部生産性のホルモンコレシストキニン(CCK−8)の合成類似体である。CCK−8は、胆嚢壁中のレセプターに作用し、収縮させ、胆嚢内に蓄積する可能性のある残留胆泥や胆汁を除去する。CCK−8は、胆汁の流動を促進し、大小腸の運動能を向上させるので、幽門括約筋を収縮させ、膵酵素の分泌作用も高める。また、CCK−8は、胆汁の腸への移動を遅らせる働きもある。シンカリドは、胆嚢の収縮および弛緩という観点から考えると、人体で生成される内因性ホルモン(CCK−8)よりも迅速な生理学的効果があるので、シンカリド製剤は、単独投与であっても、他の肝胆道造影剤との併用投与であっても、肝胆道撮像用の診断補助剤として有用である。シンカリドは、例えば、各種病状の視覚化および/または診断能を改善する目的で、画像診断(例えば、磁気共鳴画像診断、シンチグラム造影診断、超音波画像診断等)の前後に投与できる。

本発明のシンカリド製剤は、完全非経口的栄養法(TPN)を受けている患者の治療にも有用である。TPNは、胆泥、胆汁うっ滞の進行、胆石形成や、他の胆嚢関連合併症を誘発する。実際に、TPN関連胆汁うっ滞(TPN−AC)は致命的になる場合がある。TPN−ACは、敗血症、肝硬変、リンパ球機能の衰え、閉塞性黄疸、肝機能不全、そして死亡率の上昇との関連性が臨床的に示唆されている。これらの疾患がどのようなメカニズムで進行するのかは未だ決定的に証明されていないが、胆汁うっ滞、および胆嚢排出能、胆汁流量、胆汁酸分泌量の減少は、TPN−ACや他のTPN関連合併症の原因となることが示唆されている。シンカリドをTPN患者に投与し、胆嚢収縮および内容物排出を促進することにより、長期TPNに関連した疾患および他の合併症を治療および予防することができる。
シンカリド製剤に対する緩衝剤と製剤pHの影響
シンカリドの化学的安定性に対するpHの影響を測定するための実験を行った。化学的不安定性や劣化は、例えば、酸化、還元、脱アミド、加水分解、イミド形成、ラセミ化、異性化、および/またはβ脱離によって引き起こされる。リン酸緩衝溶液中でのシンカリドに対するpHの影響を調べるために、35mMリン酸緩衝液中にシンカリド溶液(約1.7μg/mL)を調製し、最終pH値を希釈HClまたはNaOHを用いて3.0〜9.1の範囲で調整した。勾配溶出を用いた逆相高速液体クロマトグラフィー(RP−HPLC)を使用し、215nmでのUV検出で、pH調整後0、6、24時間後のシンカリドの回収率を測定することにより、溶液中のシンカリドの安定性を評価した。
シンカリド製剤に対するキレート剤の効果
図1に示すように、シンカリドのアミノ酸組成には、構造配列においてMet3およびMet6として表示した2種のメチオニン(Met)が含まれる。シンカリド中に存在するこれらの残基が、遊離金属によって酸化されやすいかどうかを調べるために実験を行った。また、これらの実験で、金属をキレート化することによって、シンカリドの酸化を阻害する製剤賦形剤としてのDTPAの役割も調べた。図2〜4は、モノ、またはジスルホキシドの何れか一方を含むシンカリドの3つの酸化形を示す。金属の存在による潜在的酸化効果を評価するために、表6に示すように、1mMのDTPA(0.39mgのDTPA/mL)有り、あるいはDTPA無しの実験用製剤(アミノ酸無し)をpH6.5〜7.0で調製した。
シンカリド製剤に対する界面活性剤の効果
充てん剤/等張化剤、緩衝剤、塩、キレート剤、およびシンカリドから成る新製剤の予備開発研究において、バルク溶液中の有効薬用成分シンカリドの回収率は、外気との接触状態に影響されやすいことが、HPLC解析により確認された。例えば、逆相勾配溶出HPLCを用いて、215nmでUV検出することでシンカリドの効力をモニターした場合、開栓バイアル中の2mLバルク充填溶液を、17時間空気に暴露しながら、かき混ぜる、または静置した場合、シンカリド回収率に50〜60%というかなりの減少が見られた。このシンカリドの減少は、シンカリドモノおよびジスルホキシド劣化物の増加にある程度起因しているが、これは全減少量のごく一部でしかない。このため、この回収率の減少は、吸着/変性、あるいは気液界面効果のいずれかによるものであると考えられる。この表面吸着に伴うシンカリドの劣化を抑えるために、界面活性剤を製剤の賦形剤として、バルクあるいは凍結乾燥シンカリド製剤に加える。
シンカリド製剤に対する抗酸化剤の効果
安定剤としての抗酸化剤の添加による、シンカリド製剤のシンカリド酸化抑制効果を評価するための実験を行った(実施例4の製剤は、85mg/mLのマンニトール、0.005mg/mLのTWEEN(登録商標)20、2.75mg/mLのKH2PO4、1.0mg/mLのDTPA、2.0mg/mLのメチオニン、7.5mg/mのLリジン、15mg/mLのアルギニン、0.0025mg/mLのシンカリドを含有する(バルク製剤)、ただし、シンカリドを含まない偽薬は除く)。シンカリドメチオニン(Met3またはMet6)モノスルホキシド、脱硫化シンカリド、および未知の劣化物の形成を調査した。メタ重亜硫酸ナトリウム、アスコルビン酸、システイン、グルタチオン、硫酸ナトリウム、ベンザルコニウムクロライド、およびベンゼトニウムクロライドのシンカリド劣化阻害効果を、シンカリド回収率およびシンカリド関連不純物への影響という観点から、HPLCにより評価した。
充てん剤/等張化剤の選択
本発明の製剤中の有効薬用成分(API)シンカリド(5μg/バイアル)は微量なので、充てん剤の使用が、構造を与えおよびAPIを支持するという役割のみではなく、張度を与えるという意味でも非常に有用と思われる。本発明のシンカリド製剤中の充てん剤の選択およびその最適化のための実験を行った。評価基準は、効率的な凍結乾燥サイクル、製薬業上見栄えの良い最終製品、製品の溶解性の向上、および再構成製品の等張化賦形剤としての有用性である。ラクトース、ラクトース/塩化ナトリウム、およびマンニトールの各濃度を考慮し、これらの賦形剤入りの実験用バッチを、ケーキ形状、浸透圧(オスモル濃度)、溶解速度、凍結乾燥顕微鏡検査、および、電気抵抗対温度測定値を含む熱分析の観点から評価した。

シンカリド製剤に対するアミノ酸の効果
この製剤の研究において、空気暴露および凍結乾燥は、製剤中のシンカリドの効力が減少するために、スケールアップした製造にとって問題となる領域であることが確認されていた。シンカリドを空気に暴露すると表面吸着/変性が起こり、酸化を通じて劣化物を生成するため、その結果、効能が減少する。また、凍結乾燥中にシンカリド製剤を熱ストレスに曝すと、シンカリドの劣化物が生成され、回収率は減少する。
再構成製品の貯蔵寿命実験
A.バイアル内における再構成後の安定性
再構成後のシンカリドを室温にて8時間放置し、外観、溶解度、微粒物質、色、pH、シンカリド含有率、脱硫化シンカリド含有率、および、その他のシンカリド関連不純物の観点より、その安定性を測定するための実験を行った。シンカリド製剤の三つの105Lスケールアップパイロットバッチから採られた凍結乾燥バイアルを5.0mLの純水で再構成した。
本発明のシンカリド製剤における再構成および希釈後の安定性を測定するための実験を行った。
HPLCを用いたシンカリド特異的アッセイ
KINEVAC(登録商標)におけるシンカリド効力を測定し、脱硫化シンカリドの不純度を定量し、シンカリド関連不純物指数を測定するためのHPLC法を開発および評価した。この方法は、KINEVAC(登録商標)を製品パッケージの説明書に従って再構成する場合に、再構成後の安定性を測定するのに好適である。この逆相法は、C18(5μm、300Å)カラム、0.15%トリフルオロ酢酸水溶液(溶液A)および0.125%トリフルオロ酢酸アセトニトリル溶液(溶液B)から成る移動相を用いた階段的勾配溶出を採用し、215nmのUV検出を行った。
本発明は好ましい実施例を参照して説明したが、当業者はこの本質的な特徴を容易に認め、本発明のその精神および要旨から逸脱することなく、各種用途や条件に合わせて、各種変形や修正をなすことが可能である。当業者は、通常の実験の範囲を超えることなく、ここに説明した本発明の具体的な実施例に相当するものを多く認識しうる。このような相当物は、本発明の趣旨に包含される。
