今回の研究では、いかなる用量、スケジュール、単剤療法又は併用療法においても毒性は観察されなかった。誤投与に関する技術面による死が観察されたが、この死は薬剤に関する死ではないと考えた。
有効性データは、平均腫瘍体積±標準誤差(SEM)として図示した。治療群の腫瘍体積は、式:100×((T−T0)/(C−C0))を使用して対照群の腫瘍体積のパーセント(%T/C)として示した。「T」は実験の間の特定の日の治療群の平均腫瘍体積を表し、「T0」は同じ治療群の治療初日の平均腫瘍体積を表し、「C」は実験の間の特定の日の対照群の平均腫瘍体積を表し、「C0」は同じ治療群の治療初日の平均腫瘍体積を表した。
さまざまなスケジュールの相対的な延長寿命(ILS)は、以下の表4で示す。化合物IIIを80mg/kg毎日x5とベムラフェニブを50mg/kg bid並びに化合物IIIを100mg/kg wkとベムラフェニブを50mg/kg bidで受けた群は、寿命の延長率が最大であった。次いで、化合物IIを100mg/kg毎日とベムラフェニブを50mg/kg bidで受けた群であった。
統計的な相互比較を下の表5に示す。表で示す通り、化合物IIIを100mg/kg qwkとベムラフェニブを50mg/kg bidの併用療法及び化合物IIを200mg/kg qwkとベムラフェニブを50mg/kgの併用療法のTGI及びILSは、全ての単剤療法アームよりも統計学的に優れていた。
