Abstract
Description
本発明は、女性における減少した卵巣予備能を増加させることと、女性における外陰部萎縮症および膣萎縮症ならびに性機能障害などの閉経期に関する症状を緩和することとに有用であり、活性薬としてデヒドロエピアンドロステロン(DHEA)または硫酸デヒドロエピアンドロステロン(DHEA−S)を含み、さらに、活性薬の放出を調節する薬剤的に許容可能な賦形剤を任意に含む、膣リングに関する。
欧州諸国における統計によれば、有効な避妊が利用可能になった頃から、女性は、1980年初期の平均23〜25歳に比べて、最初の子供を平均29〜30歳で持つほどに、出産を遅らせてきた(Alviggi et al,, 2009)。さらには女性の生殖能力は平均30歳で減少し始め、年々減少する(Broekmans et al., 2009)。
AMHは前胞状卵胞および小胞状卵胞の顆粒膜細胞によって産生される二量体糖蛋白質である。産生は卵胞が始原的段階から第一期に分化する時に起こり、卵胞が、2〜6mmの直径を有する中期胞状段階に到達するまで続く。AMH産生は、FSH依存卵胞成長段階である優性段階に卵胞がいったん達すると停止する(Ueno et al., 1989, Fanchin et al., 2003, Broekmans et al., 2009)。加えて、卵胞が閉鎖段階に達した時にAMHは消失する(Visser et al., 2006)。
DHEA治療効果に特徴的な長期間の治療を可能にするために、初回通過肝代謝の影響を低減または無効化することを可能にする投与経路を通じて、一月に一度、二か月また三ヶ月に一度にのみ投与され、DHEAの使用によって緩和される病気または障害の予防または治療に用いられるDHEAまたはDHEA−Sを届ける持続放出処方の必要性が存在する。
図1−2.0gのDHEAを有しかつPVP K−30を有しないかもしくは10%または15%のPVP K−30を有する膣リングからのデヒドロエピアンドロステロン(DHEA)のインビトロ放出特性。
実施例1−DHEAまたはDHEA−Sを有する膣リング
異なる量のDHEAまたはDHEA−Sを有する膣リングを作製した。有効成分の放出調節薬を加え、調節薬は、
・PVP K−30:1%溶液中において26〜35センチストークス(26〜35のK値)の粘着性を有するポリビニルピロリドンK−30または1−ビニル−ピロリドンのポリマー
・ラウリル硫酸ナトリウム
・クレモホールRH40:エトキシレート水素付加ひまし油(CAS61788−850−0)
・AA−1ポリカルボフィル:ジビニルグリコール架橋アクリル酸ポリマー(CAS9003−97−8)
・ラクトース
・微晶質セルロース
から選択した。
表1、表1a、表2、および表2aに、試験した一般処方(GF)を詳細に示す。様々な放出調節因子と共に用いたポリマーが含まれる。
リング型に注入される全ての成分の均質な混合物を用意した。まず、各材料の必要な量を測定した:ポリマーA、必要なら放出調節薬、およびメロキシカムである。均質化するまでこれらの成分を混合し、ポリマーBを一定の混合の下で加えた。混合物を室温でリング型に注入し、それからオーブン内に105℃で1時間放置した。それから型を冷やして、形成されたリングをそれぞれの型から取り外して最終産物を得た。
表1および2の一般処方によると、異なる量のDHEAおよび薬剤放出増強因子を有する膣リングの処方が用意された。本発明の好ましい処方は表3、4、5、および6に含まれる。全ての成分量をグラム単位で示す。
表1〜6に記述される膣リングを用いたインビトロ放出試験を、以下に示す解析手順に応じて行った。処方の結果の説明時に表3〜6のアッセイ命名法を「SF−n」のように示す。ここで、nは、これらの表に示す処方の番号である。
図1は、2.0gのDHEAを有しかつPVP K−30を有しないリング(SF−11)が19.8mgのDHEA平均初期放出(1日目)を有したことを示す(表7も参照)。10%(SF−13)および15%(SF−14)のPVP K−30を有するリングからの初期放出は、この薬剤がない場合よりも高く、それぞれ平均値にして29.4および32.9mgを達成した。同様に、5%のPVP K−30を有するリング(SF−12)もまた、この薬剤がない場合に比べて高い放出を有し、DHEAが同量の場合(2.0g)に1日目に23.6gの値を達成した(表7)。全ての場合に顕著な初期低減が起こるとはいえ、最初の4日間、PVP K−30を有するリングではより顕著な放出が維持される(図1を参照)。
DHEA用量が低い(1.0g、0.5g)場合、PVP K−30の同じ効果が観察された、すなわち、PVP K−30を有するリングにおける有効成分の放出はより多く、薬剤濃度が増えるほど放出量が増えた(図2および図3)。加えて、図3に示すように、最も低い濃度のDHEA(0.5g)を有するリングでは、PVP K−30効果の飽和が観察された。15%のPVP K−30(SF−4)(丸形)および20%のPVP K−30(SF−5)(菱形)では、DHEAの放出に明白な違いは無かった。
加えて、高用量のDHEA(2.5g)を有し、かつPVP K−30を有しない(SF−11)かまたはPVP K−30を有する(SF−17およびSF−18)リングを試験した。全ての場合、試験期間中、PVP K−30を有しないリングは低量のDHEAを放出した。1〜4日目の間、PVP K−30を有しないリングは22.3mgのDHEAを放出し、5%のPVP K−30(SF−17)を有するリングは26.1mgのDHEAを放出し、10%のPVP K−30(SF−28)を有するリングは32.1mgのDHEAを放出した(図4、灰色の棒)。それに続く日(5〜30日目)では、PVP K−30が濃度が増加するとDHEA放出もまた増加し、0%、5%、および10%のPVP K−30に対してそれぞれ14.7mg、18.5g、および24.2mgであった(図5、灰色の棒)。同様に、より長い時間(31〜90日目)では、これらのリングから顕著な放出が依然として観察され、PVP K−30濃度が0%、5%、および10%の場合にそれぞれ10.8mg、4.0mg、および19.1mgであった(図6、灰色の棒)
2.5gのDHEA用量は、試験した最も高い用量であり、それゆえ、PVP K−30の有無に関わらず最も高いDHEA放出が得られた用量であった。図4〜6に示すように、全ての放出時間において、2.5gのDHEAを有しPVP K−30を有しない場合に得られる放出は、達成され、かつ、10%および15%のPVP K−30を有しかつ低濃度のDHEA(1.0gまたは0.5g)のDHEAを有するリングによって超えられた。加えて、図7に示すように、2.5gのDHEAおよび5%のPVP K−30を有するリングから得られる放出は、1.0gのDHEAおよび15%のPVP K−30を有するリングを用いて達成された。1.0gのDHEAを有しかつPVP K−30を有しないリング(SF−6)(三角形)からの放出または1.0gのDHEAおよび15%のPVP K−30を有するリング(SF−9)(四角形)からの放出は、2.5gのDHEAおよび5%のPVP K−30を有するリング(菱形)と比較された。
1.0g2.0gの用量のDHEAを有しかつ10%のラクトース(SF−22およびSF−24)、15%のラクトース(SF−23およびSF−25)、5%の微晶質セルロース(SF−26およびSF−28)または15%の微晶質セルロース(SF−27およびSF−29)を有するリング、DHEAを有するがラクトースまたは微晶質セルロースを有しないリングに比べて短期間でより高い量のDHEAを放出し;長時間では後者と同様の放出レベルが得られた。図9では、1〜22日目の間においてリングからのDHEA放出を増加させる10%および15%のラクトースの効果が観察された;しかし、23〜90日目の間では、放出レベルは、ラクトースを有するリングと有しないリングとで区別できなかった。
ポリマーCおよびD(図2、GF−11を参照)によって形成され、異なる用量のDHEAを有し、かつPVP K−30を有しないリングを試験した。示された物性のために、これらのリングはヒト用に推奨される製品として処分された。それにも関わらず、DHEAを有するリングの放出特性を評価し、そして、これらのリングは記録時間を通じてポリマーAからなるリングに比べて高い量の有効成分を放出することが観察された。
DHEAを有する膣リングは、組織レベルに達して治療効果を達成できる有効成分の必要な放出特性を有することに加えて、使用者に対する受容性必要性の他に、膣内投与を可能にする他の特性をも有しなければならない。これらのうち、膣内に挿入するための形態にするために使用者がリングを押すことができるように、リングは柔軟でなければならない。加えて、リングは、均一な滑面を有し、触りやすく、粘着性および規則的な堅さが無く、すなわち、投与が容易になるような一定の柔らかさを有しなければならない。
インビボでのDHEAの膣内放出および吸収を表すために、異なる処方の3つの膣リングを、38歳を超える9名の健康な女性ボランティアに投与した。DHEAを有しかつ調節薬を有するかまたは有しないリングを投与した後の活性薬の子宮内膜および細胞質レベルを測定した。
