由于化疗耐药,复发性卵巢透明细胞癌(OCCC)患者治疗选择有限。ENMD-2076是靶向Aurora A和VEGFR的选择性多靶点激酶。CLIN CANCER ERS近期发表了一篇文章,评估ENMD-2076的活性。

研究纳入接受过铂类化疗的复发性OCCC患者。主要研究终点是客观反应和6个月无进展生存(PFS)率。通过IHC和二代测序分析ARID1A和PTEN表达并分析其相关性。研究共纳入40名患者,中位年龄54岁,其中38名患者可进行评估。ENMD-2076耐受性良好,主要相关的3级毒性是高血压(28%),蛋白尿(10%)和腹泻(10%)。3名患者(1名未经证实)出现部分反应,26名患者病情稳定。总的6个月PFS率为22%,ARID1A表达不同(ARIDIA -对比ARID1A +)的患者存在差异。36例患者中有20例观察到PTEN阳性表达,且与预后无关。PI3KCA野生型与PI3KCA突变组患者的中位PFS 分别为5个月和3.7个月(P= 0.049)。分子测序发现PI3KCA(27%),ARID1A(26%)和TP53(7%)的变异。治疗时间最长(22个月)的患者为PTEN野生型。

文章最后认为,单药ENMD-2076未达到预设的疗效标准。ARID1A的缺失与更好的PFS相关,需要进一步研究潜在的预测性生物学标志物。
