Description
本願は、2009年2月6日に出願された米国仮特許出願第61/150,655号および2009年2月6日に出願された米国仮特許出願第61/150,652号への優先権を主張する。これらの出願の全体の内容は、本明細書中に参考として援用される。
特許文献1は、インテグラーゼ阻害剤として有用であると報告されている化合物を開示している。一つの特定の化合物は式Iの化合物である(すなわち、エルビテグラビア)。
本発明は、式I、式II、式IIIの化合物及び式IVの塩を含む固形投与形態(例えば、錠剤)並びに該固形投与形態を調製する方法を提供する。出願人は、二層の様式で調製された錠剤が、他の構造の錠剤よりも優れた性質を有することを発見した。この発見は、HIVのようなウイルス感染の処置のための併用療法の開発の進歩を示している。
a)第一の層は、
式Iの化合物:
範囲及び用語についての以下に記載されている特定の値は、説明のためだけのものであり、他の値を除くものではない。
化合物量及び化合物の重量比
本発明の錠剤は、式I、式II、式IIIの化合物及び式IVの塩を含む。本明細書に記載の重量及び比は、記載されているように、併用療法に関する。本発明の範囲内に在りながら各種化合物の量は変化し得ることを理解されたい。一実施形態では、本発明の錠剤中の式Iの化合物の量は、150mg±10%である。別の実施形態では、本発明の錠剤中の式Iの化合物の量は、150mg±5%である。別の実施形態では、本発明の錠剤中の式Iの化合物の量は、150mg±2%である。一実施形態では、本発明の錠剤中の式IIの化合物の量は、150mg±10%である。別の実施形態では、本発明の錠剤中の式IIの化合物の量は、150mg±5%である。別の実施形態では、本発明の錠剤中の式IIの化合物の量は、150mg±2%である。一実施形態では、本発明の錠剤中の式IIIの化合物の量は、200mg±10%である。別の実施形態では、本発明の錠剤中の式IIIの化合物の量は、200mg±5%である。別の実施形態では、本発明の錠剤中の式IIIの化合物の量は、200mg±2%である。一実施形態では、本発明の錠剤中の式IVの塩の量は、300mg±10%である。別の実施形態では、本発明の錠剤中の式IVの塩の量は、300mg±5%である。別の実施形態では、本発明の錠剤中の式IVの塩の量は、300mg±2%である。
薬学的製剤
本発明の薬学的組成物は、従来の担体とともに製剤化され得る。組成物の活性成分は単独で投与され得るが、薬学的製剤としてそれらを提示することがより好ましくあり得る。本明細書に記載されているように、本発明の薬学的製剤は、式I、式II、式III及び式IVの化合物を1つ以上の許容され得る担体と一緒に含み得る。担体は、製剤の他の成分と適合し、受容者にとって生理的に無害であるという意味で、“許容され得る”べきである。従って、一実施形態では、本出願は、式I、式II、式III及び式IVの化合物並びに薬学的に許容され得る担体を含む薬学的組成物を提供する。
式IIの化合物は、任意の適切な方法を用いて、シリカ粒子上に充填され得る。例えば、式IIの化合物は、
a)化合物の溶液(例えば、エタノールのようなアルコール中の化合物の溶液)をシリカ粒子に噴霧すること;
b)式IIの化合物、適切な溶媒(例えば、ジクロロメタンのような揮発性溶媒)、及びシリカ粒子を組み合わせること;該溶媒を蒸発させること;並びに、その結果として生じる固体物質を単離すること;又は
c)式Iの化合物及び適切な揮発性溶媒(例えば、ジクロロメタンのようなハロゲン化炭化水素)、及びシリカ粒子を組み合わせること;貧溶媒(例えば、ヘキサン又はヘプタンのような高度に非極性の溶媒)を加えること;並びに、その結果として生じる固体物質(実施例4で説明されるように)を単離すること、
によってシリカ粒子上に充填され得る。
式IIの化合物の調製及びシリカへの前もった充填
国際特許出願公開番号WO2008/103949に記載されているように(例えば、254頁参照)、式IIの化合物又はその塩は、式Xの酸性塩(式中、Mは対イオンである)を式IXのアミンにカップリングさせて対応する式IIのアミドを形成することによって調製され得る。
式I、式II、式III及び式IVの化合物を含む固定用量の組み合わせ錠剤の製造法は、以下の工程を含む:1)式Iの化合物の流動床造粒及び乾燥、2)式IIの化合物又はシリカ粒子上に充填された式IIの化合物の高せん断造粒及び流動床乾燥、3)式IIIの化合物の乾式造粒及び式IVの塩の乾式造粒、4)式IIIの化合物の乾式顆粒の製粉及び式IVの塩の乾式顆粒の製粉、5)式IIIの化合物及び式IVの塩のブレンド、6)式Iの化合物及び式IIの化合物のブレンド、7)式I及び式IIの化合物のブレンドからなる一方の層と式III及び式IVの化合物のブレンドからなる他方の層を用いた二層圧縮による錠剤の形成、8)錠剤のコーティング並びに9)コーティングされた錠剤のパッケージング。
以下の表は、本発明の錠剤を調製するのに有用な本発明の代表的な組成物を説明する。
式IIの化合物に関する薬物動態の用量決定試験を行った。用量決定試験のための式IIの化合物の用量としては、50mg、100mg及び200mgが挙げられた。100mg用量の用量決定試験が提供している式IIの化合物についての薬物動態のデータは、以下の表に示される。
データは算術平均(%CV)として示される;T1/2は中央値(Q1,Q3)として示される;%CV、変動係数パーセント
また、式I/式II/式III/式IVの化合物の2つの固定用量の組み合わせに関する薬物動態試験も行った。式I/式II/式III/式IVの化合物の固定用量の組み合わせの用量は、それぞれ、150mg/100mg/200mg/300mg(用量A)及び150mg/150mg/200mg/300mg(用量B)であった。2つの固定用量の組み合わせ(用量A及び用量B)に関する試験が提供している式IIの化合物についての薬物動態のデータは、以下の表に示される。
