研究认为,Tucidinostat联合依西美坦可显著改善晚期激素受体阳性HER 2阴性乳腺癌患者的无进展生存期

Tucidinostat(西达本胺)是口服选择性组蛋白去乙酰化酶抑制剂,近日研究人员考察了Tucidinostat联合依西美坦对晚期激素受体阳性乳腺癌患者的疗效和安全性。

研究在中国开展,绝经后、激素受体阳性、HER2阴性乳腺癌患者参与研究,患者先前进行内分泌治疗后复发或进展,ECOG评分0-1,随机分为两组,在25 mg依西美坦基础上,每周两次口服30mg的Tucidinostat或安慰剂。研究的主要终点是无进展生存率。

365名患者参与研究,244名患者被随机分配到Tucidinostat组,121名患者被随机分配到安慰剂组,随访时间中位数为13.9个月。中位无进展生存期,Tucidinostat组为7.4个月vs安慰剂组为3.8个月(HR =0.75)。两组中最常见的3级或4级不良事件是中性粒细胞减少(Tucidinostat vs 安慰剂,51% vs 2%)、血小板减少(27% vs 2%)、白细胞减少(19% vs 2%)。Tucidinostat组244例患者中51例(21%)发生任何原因的严重不良事件,安慰剂组为7例(6%)。

研究认为,Tucidinostat联合依西美坦可显著改善晚期激素受体阳性HER 2阴性乳腺癌患者的无进展生存期。
