Description
この出願は、米国特許第5,192,756(1993年3月9日に発行)、米国特許第6,962,909(2005年11月8日に発行)および米国特許第7,981,876(2011年7月19日)と技術的に関係しており、その全てを参照により本明細書に組み込む。
本発明は、眼の症状、例えばウェット型加齢性黄斑変性症(ウェット型AMD)、脈絡膜血管新生、網膜症、ドライ型加齢性黄斑変性症(ドライ型AMD)、ポリープ状脈絡膜血管症、眼科手術後の血管新生、黄斑浮腫、網膜静脈閉塞症、下脈絡膜血管新生、網膜上皮剥離、翼状片または網膜色素上皮の中央窩地図状萎縮などの処置のための、スクアラミンまたはその医薬上許容し得る塩の眼用製剤に関する。
加齢性黄斑変性症(AMD)は、アメリカ合衆国の中で52歳またはそれ以上の年齢の人々の中で不可逆的な中心視力損失の主要病因であり、アメリカ合衆国、カナダ、英国およびオーストラリアにおける失明の最も一般的な総合的原因である。AMDは、罹患患者の黄斑にて進行する幾つかの異常症状を含む。黄斑変性症には2つの形態が存在する:ドライ型(萎縮型としても知られる)およびウェット型(円盤状、滲出性、網膜下血管新生または脈絡膜血管新生としても知られる)。ウェット型の前兆ともいえるこのドライ型は、網膜により生成した不要物質を排出する黄斑色素上皮の能力欠損により生じる。ウェット型は、新しい血管が網膜下、特に黄斑で成長する場合におこる。
本発明の一態様は、スクアラミンまたはその医薬上許容し得る塩、1以上の粘膜接着剤および1以上の浸透増強剤を含む、局所用の眼用用途のための組成物である。
例示的な実施形態において、本発明の眼用製剤は、スクアラミンまたはその医薬上許容し得る塩、粘膜接着剤および浸透増強剤を含有する。該製剤は、所望により以下の少なくとも1つの成分を含むが、これに限定するものではない:(a)張度改変剤;(b)抗菌性防腐剤;(c)緩衝剤;(d)界面活性剤;(e)安定化剤;(f)可溶化剤または再懸濁剤;(g)別の粘膜接着剤;および(h)別の浸透増強剤。

スクアラミンを用いるHUVECによるVEGF誘導性血管形成の阻害
スクアラミンラクテートを、50、100または200nM濃度の溶液中でヒト血管内皮細胞(HUVEC)の懸濁液と共に混合した。次いで、該懸濁液を、直ぐに血管内皮細胞成長因子(VEGF)を含む複数の成長因子を含有したMatrigel上に播種した。該プレートを、24時間95%O2/5%CO2の大気中において37℃でインキュベートし、次いでプレートを撮影した。結果を図1に示し、スクアラミンが50nM濃度でさえ血管形成を妨害することを示す。
