テスト材料(SPL-7013とも呼ばれる式I、粉末およびゲルプラセボ)は、アッセイされるまで周囲条件で貯蔵した。
アッセイ用のテスト生物は、最近の臨床的分離株または米国培養細胞系統保存機関(ATCC;マナサス、VA)から入手した参照株であった。アッセイに含めた品質対照生物は、バクテロイデス・フラギリス(bacteroides fragilis) 0123 (ATCC 25285)であった。
嫌気性寒天希釈MICアッセイに使用した培地は、ヘミン(Strem Chemicals、ロット#07.0830)、ビタミンK1 (Pfaltz and Bauer、ロット#9799)、および溶解ヒツジ血液(Cleveland Scientific、ロット#S03582)を補充したブルセラ寒天(Becton Dickinson、スパークス、MD #211086、ロット#7166673)であった。全ての培地は、臨床検査標準協会(CLSI)ガイドライン(1、2、3)に従って調製した。ブロス微量希釈アッセイのため、培地を105%標準重量で調製して、最終微量希釈パネル/寒天プレートで5%薬液容量(10μL薬液)を相殺した。
嫌気性細菌は、以前に記載されている基準寒天希釈法(reference agar dilution method) (NCCLS. Methods for Antimicrobial Susceptibility Testing of Anaerobic Bacteria; Approved Standard?第6版 NCCLS document M11-A6 [ISBN 1-56238-517-8]. NCCLS、940 West Valley Road、Suite 1400、Wayne、Pennsylvania 19087-1898 USA、2004)を用いてアッセイした。薬剤希釈および薬剤補充寒天プレートは手で調製した。播種後、薬剤補充プレートをBactron IIの嫌気性環境で35℃、48時間インキュベートした。MICは、CLSIガイドライン(上述したNCCLS)により判定した。
水性SPL-7013の溶液の抗微生物特性を評価するために、2つの水溶液を、1つ目は5%w/vで、2つ目は28%w/vで調製した。1ヵ月間にわたって微生物の増殖を制限する各溶液の能力を試すために、標準的保存有効性テスト(USP<51>「抗微生物有効性テスト」に従って)を行った。
SPL-7013の試料(7.5402g)を、溶解を促進するために試料を撹拌しながら水(150mL)に溶解した。得られた混合物は、5.0268%w/vとして計算された濃度を有した。
SPL-7013の試料(42.0012g)を、溶解を促進するために試料を撹拌しながら水(150mL)に溶解した。得られた混合物は、28.0008%w/vとして計算された濃度を有した。
SPL-7013試料溶液は調製されたままの状態で使用し、USP<51>「抗微生物有効性テスト」に従ってテストした。この中で、溶液に5種類の微生物を負荷し、各微生物の集団を時間の関数としてモニターする。
緑膿菌(Pseudomonas aeruginosa)、ATCC 9027
黄色ブドウ球菌、ATCC 6538
カンジダ・アルビカンス、ATCC 10231
黒色アスペルギルス(Aspergillus niger)、ATCC 16404
大腸菌、ATCC 8739
臨床試験を実施し、臨床的に診断されたBVを有する66名の女性を4つの群に無作為化した。
1. 5g 3% SPL-7013ゲル、毎晩、7日間
2. 5g 1% SPL-7013ゲル、毎晩、7日間
3. 5g 0.5% SPL-7013ゲル、毎晩、7日間
4. 5g HECプラセボゲル、毎晩、7日間
BVの再発の予防に関する臨床試験
BVの再発の予防のため経膣的に投与されたSPL-7013ゲルの安全性および有効性を判定するための二重盲検、多施設、無作為化、プラセボ対照、用量範囲探索試験を計画する。
主要評価項目は、SPL-7013ゲルの16週間の使用の終了時のBVの存在または非存在である。
8週間の追跡調査来院時(24週目)のBVの存在または非存在
初回メトロニダゾール治療の終了からBVの再発までの時間
対象が報告した症状、Amselの基準、Nugentスコア基準、およびBV Blue(登録商標)テスト結果を含む、BVの個々の基準の存在または非存在
薬物療法に関する治療満足質問票(Treatment Satisfaction Questionnaire for Medication)(TSQM)を用いて評価した治療認容性
BV以外の膣感染症の発生
BVの現在のエピソードおよび再発性BVの既往(現在のエピソードを含む、過去12ヵ月における少なくとも3回の文書化されたエピソードとして定義)を含んだ18〜45歳の女性対象。
最大1週間のスクリーニング期間、7日間の非盲検期間のメトロニダゾールによる治療(「急性治療段階」)、16週間のSPL-7013ゲルまたはHECプラセボゲルによる治療(「二重盲検治療段階」)、および8週間の追跡調査期間(「追跡調査段階」)を含む、約26週間の全期間。
書面によるインフォームドコンセントの提供および最大1週間のスクリーニング期間後、適格参加者は、7日間コースの経口投与メトロニダゾール(1日2回500mg)を受ける。参加者は次いで、メトロニダゾールによる非盲検治療の終了後4日目+/-1日にBVの評価を持つ。
試験責任医師により観察され、もしくは試験責任医師に報告され、または対象日記カードに書かれた有害事象ならびに性器の炎症の徴候および症状が評価される。BV以外の膣感染症の発生、併用薬使用、および治療レジメンの遵守も評価される。追加の安全性パラメータは、検尿、理学的および骨盤内/婦人科検査、病歴および性交歴、バイタルサイン、尿妊娠テストならびに症状評価を含む。
1次分析は、2つの選択されたSPL-7013ゲル用量(0.5%または1%または3%からの) vs HECプラセボゲルの比較である。
