・図1からわかるように、ストレス条件(40℃)下では、ベンジルアルコールを0.9%含む製剤(MS-1とMS-2)で酸化の増加がより大きい。
・図2からわかるように、加速条件(25℃)下では、ベンジルアルコールを含むすべての製剤で、ベンジルアルコールを含まない製剤(MS-3、参照基準)と比べて酸化の増加が大きい。
・長期にわたって保管(2〜8℃)すると、ベンジルアルコールを0.9%含む製剤(MS-1とMS-2)でより大きな酸化速度が観察された。それと同等の分解速度が、ベンジルアルコールを0.45%未満含む製剤で検出された(図3)。
・図4からわかるように、ストレス条件(40℃)下では、ベンジルアルコールを0.9%含む製剤(MS-1とMS-2)で凝集体の増加が観察された。図5と図6からわかるように、加速条件かつ長期保管条件(25℃と、2〜8℃)下では、どの製剤でも凝集体の増加は観察されなかった。
・ベンジルアルコールを0.9%含む製剤(MS-1とMS-2)で40℃にて生物活性の低下が観察された。この現象は、同じサンプルを25℃で保管した場合や2〜8℃で保管した場合には観察されない。
・どの温度で保管しても力価の低下は観察されなかった。
・どの温度で保管してもpHのシフトは起こらなかった。
・3つのバッチについて、40℃における共通の傾斜と切片を計算した。共通の傾斜は1.42%/週であり、共通の切片は2.72%である。
・3つのバッチについて25℃における共通の傾斜を計算することはできなかった(P値=0.095)。したがって最悪のケース(MS-3)の結果を使用した。1ヶ月保管した後に酸化形態が1.17%増加することが観察された(0.27%/週)。
・3つのバッチについて2〜8℃における共通の傾斜を計算することはできなかった(P値=0.016)。したがって最悪のケース(MS-3)の結果を使用した。1ヶ月保管した後に酸化形態が0.2%増加することが観察された(0.047%/週)。
・候補製剤Bは、0.2%のベンジルアルコールを含む複数回用量製剤であり、そのまま使用できる。
・製剤Aは、0.3%のベンジルアルコールを含む複数回用量製剤であり、2つのカートリッジ(一方は活性成分と賦形剤を含んでおり、もう一方は、最終状態にするのに必要な量のベンジルアルコールを含んでいる)の内容物を混合した後に得られる。
・これらの候補溶液をより大きなpH(4.5±0.2)でも調べたが、安定性プロファイルに顕著な変化は見られなかった。出願人は、今や、IFN製剤のこのわずかに大きなpHが、皮下注射の局所的寛容性を増大させることを見いだした。したがってpHが4.5または4.7の上記2つの候補溶液は、患者のコンプライアンスに関して従来よりも大きな利点を提供することができよう。
