関連出願の相互参照
本特許出願は、2011年11月15日に出願された米国特許仮出願第61/559,830の優先権を主張し、その内容全体は、参照により本明細書に組み込まれる。
シクロスポリンA(CsA)は、以下の化学構造:
ポリソルベート80からの沈殿によるもの
シクロスポリンAのForm2は、ポリソルベート80(ポリオキシエチレンソルビタン−モノ−オレエート)を含む水中に、非晶質シクロスポリンAを懸濁させた後、溶液を約55℃〜約75℃の温度に加熱して、少なくとも約18時間〜約48時間、その温度で保存し、その後、沈殿物であるシクロスポリンAの形態2を除去することによって得てもよい。
シクロスポリンAの形態2はまた、シクロスポリンAの形態2を種結晶として使用して形成してもよい。この方法では、非晶質シクロスポリンAをポリソルベート80の水溶液に懸濁させ、この溶液を、上述のとおりに加熱することができる。その後、溶液にシクロスポリンAの形態2を種として入れ、続いて溶液を上述の温度で上述の時間維持し、その間常に溶液を攪拌することができる。この工程の終わりに、さらに沈殿物を上述のとおりに回収することができる。
非常に一般的に述べれば、シクロスポリンAの形態2を、1)シクロスポリンAを、水中、または,水とアセトニトリル、1,4−ジオキサン、若しくはエタノールとの溶液中のどちらかに懸濁させること;2)懸濁液を特定の速度で加熱すること;3)懸濁液を特定の速度で冷却すること;4)この加熱と冷却のサイクルを反復すること;5)および結果として得られた沈殿物を回収することによって得てもよい。溶媒の選択が非常に重要であり:ある溶媒によってCsA形態2の形成が生じるかどうか、予測が得られる構造的特徴または他の性質を、本発明人らは見出だすことができなかった。
本発明をさらに、以下の実施例により例示する。
本発明の方法により得られたCsA形態2を、シクロスポリンAによる(Restasis(登録商標)による等の)局所治療に適したどんな眼の状態の治療にも使用してよい。例えば、本発明の組成物を、数ある状態のうち、ドライアイを患う患者の治療、眼瞼炎および瞼板腺疾患の治療、眼の屈折矯正手術に起因して障害をうけた角膜知覚の回復、アレルギー性結膜炎、およびアトピー性角結膜炎および春季カタルの治療、および翼状片(ptyregia)の治療、結膜と角膜の炎症、角結膜炎、移植片対宿主病、移植後緑内障、角膜移植片、真菌性角膜炎、タイゲソン表層点状角膜炎、ぶどう膜炎、およびテオドール上輪部角結膜炎に使用してもよい。
