ジクロフェナクナトリウムを含有する貼付剤を以下の方法で調製した。粘着剤層の各成分(下表の組成を示す)を混和し、剥離ライナー(離型処理をしたPETフィルム)上に膏体質量が214g/m2となるように展延した。展延した粘着剤層上に支持体層を積層し、貼付剤を得た。貼付剤を7cm×10cmの大きさに裁断した。支持体層は透湿度が5667g/m2・24時間のPET編布を使用した。
ジクロフェナクナトリウムを含有しない点以外は同じ組成のプラセボ貼付剤を上記と同様の方法で調製した。
用量調節期において、疼痛を伴うがん患者にジクロフェナクナトリウムを含有する貼付剤を1日1回、胸部、腹部、腰部、背部、上腕部又は大腿部等に1枚貼付し、1日毎に貼り替えた。鎮痛効果が十分でない場合は、貼付する枚数を2枚、3枚と順に増やした。本評価期間は6日~22日間とした。この期間内に以下に示す基準を全て満たした患者のみ、以降の二重盲検期に移行した。
(1)移行判定日直前3日間のVAS(Visual Analogue Scale)値の平均値が、事前検査時点(用量調節期間開始前)のVAS値と比較して15mm以上改善している。VAS値の測定は就寝前に行った。
(2)移行判定日を含む直前3日間に救済措置(レスキュー)を使用していない。
(3)移行判定日の患者の疼痛改善度の評価が「完全改善」、「著明改善」又は「中等度改善」。なお、疼痛改善度の評価は医師による問診に基づき、「完全改善」、「著明改善」、「中等度改善」、「軽度改善」、「不変」及び「悪化」の6段階で評価した。
用量調節期において、疼痛を伴うがん患者にジクロフェナクナトリウムを含有する貼付剤を1日1回、胸部、腹部、腰部、背部、上腕部又は大腿部等に2枚貼付し、1日毎に貼り替えた。鎮痛効果が十分でない場合は、貼付枚数を3枚に増やした。本評価期間は2週間~4週間とした。この期間内に以下に示す基準を全て満たした患者のみ、以降の二重盲検期に移行した。
(1)移行判定日前3日間のVAS値が全て、事前検査時のVAS値と比較して15mm以上改善している。
(2)移行判定日の患者の疼痛改善度の評価が「完全改善」、「著明改善」又は「中等度改善」。
