Description
本願は、2011年11月15日出願の米国仮特許出願第61/559,838号および2011年11月23日出願の米国特許仮特許出願第61/563,199号の優先権を主張し、両出願の内容全体は、参照により本明細書に援用される。
シクロスポリンA(CsA)は、以下の化学構造
シクロスポリンAは、非晶質形、液晶形、正方晶形(1型)および斜方晶形(3型)で存在することが知られている。新規の結晶形である、シクロスポリン2型は近年発見された。
Xは、水分子の数であり、0〜3の値をとる。一実施形態において、上記の式中のXは2である。
本発明の組成物は、眼科的に許容可能なシクロスポリンA2型の製剤である。「眼科的に許容可能な」ことにより、本発明は、ヒトなどのほ乳類の眼に投与される際に、非刺激性となるように、懸濁液を製剤化することを意味する。
本発明の製剤を、(Restasis(登録商標)などの)シクロスポリンAでの局所治療に受け入れられることが知られているいずれかの眼の状態を治療するために本明細書に記載される濃度で使用してもよい。たとえば、本発明の組成物を使用して、ドライアイを患う患者を治療し、眼瞼炎およびマイボーム腺疾患を治療し、眼の屈折矯正手術のために損傷した角膜知覚を回復させ、アレルギー性結膜炎ならびにアトピー性角結膜炎および春季カタルを治療し、翼状片(ptyregia)、結膜および角膜の炎症、角結膜炎、移植片対宿主病、移植後の緑内障、角膜移植、真菌性角膜炎、タイゲソン点状表層角膜炎、ブドウ膜炎、およびセオドア性(Theodore)上輪部角結膜炎や、その他の状態を治療してもよい。
本発明の製剤を、結膜下腔に投与する。本明細書に使用されるように、「結膜下腔」は、以下の、(1)眼球結膜およびテノン鞘の間ならびに角膜縁から円蓋まで延びる潜在的な空間、(2)眼瞼結膜および瞼板の間ならびに眼瞼の境界(眼瞼の皮膚粘膜結合部)から円蓋まで延びる潜在的な空間、ならびに(3)結合部(junctional bay)または円蓋での円蓋部結膜下方の潜在的な空間のうちのいずれかを意味する。この結膜下腔は、ちょうど目の縁から結膜の下方、円蓋周辺、眼瞼の境界までの潜在的な空間である。
