Description
本出願は、2003年12月22日出願の米国実用出願(出願番号はまだ与えられていない、代理人整理番号第1767.2011−000号)の優先権を主張し、その全教示を参照により本明細書中に援用される。
現在、米国食品医薬品局によって承認された組織増大(tissue augmentation)充填剤は全てコラーゲンに由来する。ヒト被験体のおよそ3〜5%がウシコラーゲンに対して重篤なアレルギー反応を示し、かくして、個々の被験体においてこれらの充填剤を使用する前に慎重な試験が要求される。
本発明は、組織増大および/または薬剤送達のために有効なヒアルロン酸(HA)組成物およびHA組成物を製造し、使用する方法を対象とする。
HA'-U-R2-U-HA'
によって表される架橋を含有する。
本発明は、架橋HA組成物、それらの製造およびそれらの使用方法を対象とする。
HA'-U-R2-U-HA'
に示すような、各末端のU基を通してHA'分子に結合している連結基、によって特徴づけられる架橋を含み得る。
R1-N=C=N-R2-N=C=N-R1
(式中、R1で置換された2個のカルボジイミドは、連結基R2を通して結合されている)
に示す、ビスカルボジイミド架橋試薬とHA'の反応において生成することができる。
HA'-U-R2-U-HA'
(式中、変数は上述した値を有する)
によって表わされる架橋を含む。組成物は、4cmの平面幾何学的外形を用いて1Hz周波数で測定したとき少なくとも約50Paの貯蔵弾性率G'、および1s−1のせん断速度で測定したとき少なくとも約20,000cPsの動粘度から選択される、37℃で測定した少なくとも1つのパラメータを有する。また組成物は、ヒアルロニダーゼとの反応に適する条件下で、組成物を約0.3重量%のヒアルロニダーゼ酵素と37℃で組み合わせたとき、16時間の反応後に測定される組成物についてのG'値は、反応の約15分未満で測定されるG'値の少なくとも約5%である。他の態様では、16時間の反応後に測定される組成物についてのG'値は、反応の約15分未満で測定されるG'値の少なくとも約50%である。
各MES緩衝液について、2−[N−モルホリノ]エタンスルホン酸(MES水和物)(14.6g)を滅菌水980mLに溶解した。3つの溶液の各々に関して、0.1N NaOHの添加によってpHを所望値(5.5、6.0又は6.5)に調整した。1Lの容量になるように滅菌水を添加した。
各個別リン酸緩衝液について、表1に示す量のリン酸ナトリウム12水和物(Na3PO4・12H2O)、塩酸リドカイン(リドカイン・HCl)、リン酸水素ナトリウム(Na2HPO4)及びリン酸二水素ナトリウム1水和物(NaH2PO4・H2O)を溶解するために滅菌水1Lを使用した。
以下の実施例の各々において、試薬は表2に示す量で使用した。非架橋HAを、明示したpHのMES緩衝液133.4mLに溶解し、p−フェニレン−ビス(エチルカルボジイミド)(PBCDI)の15mg/mLアセトン溶液と合わせ、PBCDI:HAの明示したモル当量比(MER%)及びモル%を生じた。反応混合物を十分に混合し(例えば約1分間の、ガラス棒又はオーバーヘッド(overhead)機械式攪拌器のいずれかによる混合は透明な反応混合物から白色ペーストを生じさせる)、混合物を室温で約72時間放置した。塩化ナトリウム(6.5g、混合物を塩化ナトリウム5重量%にするために)を生じたゲルに混合し、それを1時間放置した。強く攪拌したエタノール約1.2Lに添加することによって架橋HAゲルを沈殿させた。沈殿物を収集し、減圧下で乾燥して、架橋ヒアルロン酸を生成した。
p−フェニレン−ビス(エチルカルボジイミド)とヒアルロン酸の架橋は、フェニレンUV発色団を架橋生成物に組み込む。架橋生成物のUV吸光度を測定することにより、UV発色団の量及びビスカルボジイミド由来のリンカーを組み込んだ架橋度を定量することができる。
0.1mg/mL溶液を作製するために、実施例5、6及び7の架橋生成物の各計量した量(1〜10mg)を、別々に、密封容器において70〜75℃で4時間加熱することによって十分量の5%硫酸溶液に溶解し、室温で16時間放置した。これらの溶液を各々5%硫酸で希釈して、各生成物の0.1mg/mL溶液を作製した。249nmで測定したこれらの溶液のUV吸光度を図2に示す。
実施例5の乾燥した架橋HA沈殿物の一部を低温ミルで粉砕した。粉末をジメチルスルホキシド(DMSO)に懸濁し、懸濁液を4〜10時間攪拌した。懸濁液を遠心分離し、DMSOを除去した。水不溶性架橋HAをエタノールに再懸濁し、数時間攪拌して、エタノールを除去した(所望する場合はエタノール洗浄を反復することができる)。エタノールの除去後、固体を収集し、真空下で乾燥した。架橋HAの乾燥粉末をリン酸緩衝液4に懸濁して、スラリー又はペーストの形態の30mg/mL懸濁液を作製した。NaClを添加することによって懸濁液の浸透圧モル濃度を280〜340mOsm(ミリオスモル)に調整し、注射器に充填した。注射器を、120℃、約138kPa(キロパスカル)(20 lb/in2)の圧で25分間加圧滅菌し、滅菌後冷水で冷却した。
実施例12のゲルのレオロジー挙動(貯蔵弾性率G'を含む)をRheometer AR-1000 (TA Instruments, New Castle, DE)で評価した。測定条件は、温度=37℃、測定幾何学的外形=平面プレート、200μm(マイクロメーター)の間隙(gap)、及び1Hzの周波数を含んだ。これらの条件下で、実施例12で製造したゲルの貯蔵弾性率G'は1076Pa(パスカル)と測定された。
ゲルを押出すために必要な力は、ゲルを1mLガラス製注射器[30ゲージ(内径約150μm、断面積0.0177mm2)の針を備え、0.635cmの内径を有するに充填することによって特性決定することができる。4mL/hの速度で針を通してゲルを押出すために必要な力を、力センサーシステム(Load Cell SLB-50, Transducer Techniques, Temecula, CA)を取り付けた注射器ポンプ上に注射器を置くことによって測定した。約25℃及び4mL/hの押出速度で、測定された押出力は10.7N(ニュートン)(2.4ポンド)であった。
酵素加水分解に対する架橋ヒアルロン酸の耐久性は、測定した量のヒアルロニダーゼ酵素とゲルを一緒にし、貯蔵弾性率を時間の関数として記録することによるインビトロ試験によって測定することができる。
実施例5からの乾燥した沈殿した架橋HAを低温ミルで粉砕し、実施例12で述べたようにDMSOとエタノールで洗浄した。エタノールを除去した後、固体を収集し、真空下で乾燥した。架橋HAの乾燥粉末を、互いの上に置いた5つのふるい:25μm、75μm、125μm、180μm及び250μm、に従って平均直径によって分画した。粒子の5つの平均直径画分:0〜25μm、25〜75μm、75〜125μm、125〜180μm及び180〜250μm、を収集した。各画分をリン酸緩衝液5に懸濁して32mg/mL懸濁液を作製した。懸濁液の浸透圧モル濃度を280〜340mOsm(ミリオスモル)に調整し、各懸濁液を注射器に充填した。注射器を、120℃、約138kPa(キロパスカル)(20 lb/in2)の圧で約45分間加圧滅菌し、その後冷水で冷却した。
実施例5からの乾燥した沈殿した架橋HAを粉砕し、実施例12で述べたように洗浄した。架橋HAの乾燥粉末の一部を、次に、250μmふるいでふるい分けた。平均直径250μm未満の全ての粒子を収集し、リン酸緩衝液4に懸濁して32mg/mL懸濁液を作製した。
実施例5及び6の各々からの乾燥した沈殿した架橋HAの一部を粉砕し、実施例12で述べたように洗浄した。各部分を250μmふるいでふるい分けた。平均直径約250μm未満の粒子を収集し、リン酸緩衝液4に懸濁して32mg/mL懸濁液を作製した。
実施例5に従って得、実施例12に従って処理した架橋HAを、450Paの初期G'を有するゲルにした。ヒアルロニダーゼによる消化に対するこの生成物及び3つの競合組織増大製品RESTYLANE(登録商標)、PERLANE(登録商標)(どちらもQ-Med, Uppsala, Sweden)及びHYLAFORM(登録商標)(Genzyme, Cambridge, MA)の抵抗性を評価した。ヒアルロニダーゼ溶液(食塩水で調製した1.9mM リン酸緩衝液中のヒアルロニダーゼの0.15mg/mL溶液15μL、約2.5単位)を添加し、各製品0.75g と十分に混合した。各混合物を注射器に充填し、気泡を除去するために1500rpmで1分間遠心分離した。次いで、各混合物0.35gをレオメータープレートに負荷した。酵素の添加時点から15分後にデータの蓄積を開始した。ゲルの貯蔵弾性率G'を、温度=37℃、平面プレートの測定幾何学的外形、200μmの間隙、及び1Hzの周波数で、10分間隔で16時間記録した。
図6は、約200〜約1200Paの初期貯蔵弾性率値を有する一連の架橋HA組成物の16時間にわたるΔG'/Δtを示す。上記実施例に従って組成物を調製し、測定を実施する。理解されるように、架橋HA組成物の分解は、基本的にこの16時間の期間にわたって初期貯蔵弾性率G'とは無関係である。
リドカインは相乗作用を有し得、リドカインを含まない緩衝液で製造した、他の点では同一の組成物と比較して、ゲルの初期貯蔵弾性率G'を上昇させることができる。実施例5の架橋HAを、3つの別々のリン酸緩衝液1(リドカインなし)、2(0.2%リドカイン)、及び3(0.3%リドカイン)を用いて実施例12におけるように処理した。ゲルを32mg/mL濃度にし、実施例12で述べた方法に従って各貯蔵弾性率G'及び分解プロフィールΔG'/Δtを測定した。図7は、リドカインを含む組成物が試験の期間を通じて有意に高い率G'を有することを示す。したがって、リドカインを含む架橋HAは良好な生体安定性を有し得、一部の場合は、G'を上昇させる相乗作用を有し得る。
本研究において使用する架橋HA生成物を、実施例14で述べた手順に従って製造した。モルモットモデルでの皮内(interdermal)注射研究において、架橋HA生成物及び対照製品(ZYDERMTMII, Collagen, Palo Alto, CA)を皮内注射した。各注射部位(各試料につき各時間間隔で6箇所)は、2、4、8及び12週目に高さ及び直径を測定した。標本を各時間間隔で組織学的評価のために外植した。
