Abstract
Description
1)ILDの他の原因の排除、
2)肺活量の制限及び/若しくはガス交換の障害、又は一酸化炭素の拡散能力(DLCO)の低下の証拠を含む、異常な肺機能試験、
3)従来の胸部X線写真又は高分解能コンピュータ断層撮影(HRCT)スキャン上の異常。
上記に定義したエンドセリン受容体拮抗薬は、幅広い構造を包含し、単独で、又は組み合わせで本発明の方法に有用である。本発明に使用し得るエンドセリン受容体拮抗薬の非限定的な例は、以下に開示するエンドセリン受容体拮抗薬を含む。以下に同定するエンドセリン受容体拮抗薬の引用は、その全体が本明細書に組み入れられる。
表1
アトラセンタン、アボセンタン、テゾセンタン、クラゾセンタン及びプロピル-スルファミン酸{5-(4-ブロモ-フェニル)-6-[2-(5-ブロモ-ピリミジン-2-イルオキシ)-エトキシ]-ピリミジン-4-イル}-アミド。
エンドセリン-1(ET-1)が線維症の発症に中心的な役割を果たし、それ故ET-1の作用を標的とし、阻害するのに使用される薬物は、初期線維症の治療に有効であろうことから、ボセンタンを用いた発見は、上記した他のエンドセリン受容体拮抗薬に外挿することができる。
実験は、マウス胚線維芽細胞の細胞ラインSwiss 3T3 (Deutsche Sammlung fur Mikroorganismen und Zellen, DSMZ ACC 173)にて実施した。細胞を血清フリー培地又は0.5%血清を含有する培地中で24時間飢餓させた後、その最大効力の約50%又は好ましくは80%を与える濃度のエンドセリン-1と共に、ビヒクル又は増大する濃度の拮抗薬、又はピルフェニドンと組み合わせた拮抗薬のいずれかの存在下、24時間インキュベートした。
実験結果:
このSwiss 3T3マウス胚線維芽細胞を用いた初期線維症の細胞培養モデルにおいて、コラーゲン新合成上のET-1の濃度依存性効果を測定し、0.24nMのEC50(最大効果の50%を与えるET-1の濃度)を得た。1nM(EC80)のET-1濃度を用いて、以下に言及するエンドセリン受容体拮抗薬を、ET-1誘導コラーゲン新合成上の拮抗活性に関して分析した。図1に、選択した試験化合物に関する代表的な用量応答曲線を示す。表2に、試験した7種のエンドセリン受容体拮抗薬の概要を表す。

BUILD1試験は、IPF患者における多施設、無作為化、二重盲検、プラセボコントロールによる第II/III相試験であった。この試験の目的は、ボセンタンが、6分間の歩行試験(6MWT)距離により評価して、IPF患者の運動容量を改善することを証明することである。試験の第二の目的は、ボセンタンが、死又は治療の失敗に至る時間を遅延させ、肺機能試験(PFT)、呼吸困難及び生活の質を改善し、及びこの安全性の解析対象集団にて安全かつ良好な忍容性を示すことを証明することである。治療の失敗は、PFTの悪化、又はIPFの急性代償不全の発生のいずれかとして定義された。PFT悪化は、以下の3基準のうちの2つとして定義された。
*努力肺活量(FVC)における、ベースラインからの≧10%低下。
*一酸化炭素(DLCO)の拡散容量における、ベースラインからの≧15%低下。
*休息時のO2飽和(血液ガス)における、ベースラインからの≧4%低下、又は肺胞毛細血管O2勾配(A-a PO2)における、ベースラインからの≧8mmHg増加。

解析セット:治療集団−外科的肺生検を実施した患者
対照的に、外科的肺生検(SLB)なしで診断された58人の患者が、治療効果を全く示さなかった(相対リスク比1.36、95% CI 0.70-2.65)。この観察が単に偶然の結果によるものか否かは、それら患者の2亜群のベースライン特性を比較することによってのみ決定し得た。
表4
表5に示すように、唯一の明らかな相違は、非SLB患者が、SLB患者と比較して高齢であることであった。肺機能試験は、2群間で良く均衡していた。
