PF-03084014, a γ-secretase inhibitor, was tested against the PPTP in vitro cell line panel (1.0 nM to 10 μM) and against the in vivo xenograft panels (administered orally twice daily on Days 1-7 and 15-21). PF-03084014 demonstrated limited in vitro activity, with no cell line achieving ≥50% inhibition. PF-03084014 induced significant differences in EFS distribution in 14 of 35 (40%) solid tumor xenografts, and 1 of 9 ALL xenografts (which lacked a NOTCH1 mutation), but objective responses were not observed. PF-03084014 demonstrated limited single agent activity in vitro and in vivo against the pediatric preclinical models studied.
PF-03084014,一种γ-分泌酶抑制剂,在体外细胞系(1.0 nM 至 10 μM)和体内异种移植(每天口服两次,第 1-7 天和第 15-21 天)中进行了测试。PF-03084014在体外表现出有限的活性,没有一个细胞系的抑制率达到≥50%。PF-03084014在 35 个实体瘤异种移植中的 14 个(40%)和 9 个 ALL 异种移植中的 1 个(没有 NOTCH1 突变)中诱导了 EFS 分布的显著差异,但未观察到客观反应。PF-03084014在体外和体内对所研究的儿科临床前模型表现出有限的单药活性。
