Ariad制药公司已启动了ponatinib的一项III期随机试验。Ponatinib是一种实验性Pan-BCR-ABL抑制剂,在临床前研究中,该药也能选择性抑制其他某些酪氨酸激酶,包括FLT3、RET、KIT、FGF、PDGF受体等。 Ponatinib 的EPIC试验,将在慢性粒细胞白血病(CML)新诊患者中开展。(注:EPIC,Evaluation of Ponatinib versus

Ariad制药公司已启动了ponatinib的一项III期随机试验。Ponatinib是一种实验性Pan-BCR-ABL抑制剂,在临床前研究中,该药也能选择性抑制其他某些酪氨酸激酶,包括FLT3、RET、KIT、FGF、PDGF受体等。

Ponatinib 的EPIC试验,将在慢性粒细胞白血病(CML)新诊患者中开展。(注:EPIC,Evaluation of Ponatinib versus Imatinib in Chronic Myeloid Leukemia,在CML中评价ponatinib vs imatinib)

该项试验,将以12个月时主要分子反应率(major molecular response ,MMR)为评价的主要终点,对ponatinib和imatinib的疗效进行对比。

Ariad董事长兼CEO Harvey Berger称:"近年来,新诊CML患者的治疗已转向使用第二代BCR-ABL抑制剂。该项EPIC试验将评价ponatinib是否能在新诊CML患者中产生抗白血病反应,以及是否可能阻止在其他酪氨酸酶抑制剂治疗中所观察到的耐药突变的出现。"

约500例患者将随机1:1接受标准剂量的ponatinib(45mg,每天口服一次)或imatinib(400mg,每天口服一次)。

该试验的主要终点是治疗12个月时的MMR比例,次要终点包括5年MMR,3个月MR(BCR-ABL的转绿水平降至10%或以下),12个月时完全细胞遗传学反应率、无进展生存期,整体存活率。
