致力于抗肿瘤新药开发的中美跨国制药公司徐诺药业在临床前研究中发现其候选新药艾贝司他可以高效穿过血脑屏障,此项研究与美国内布拉斯加大学医学中心合作完成。
研究发现:
· 艾贝司他可高效地穿过血脑屏障,并与替莫唑胺产生明显的协同效应;
· 在实验动物模型中,艾贝司他与替莫唑胺联用的抗肿瘤作用明显优于替莫唑胺单药或替莫唑胺与伏立诺他联用。

鉴于以上优良的临床前数据,徐诺药业计划与内布拉斯加大学医学中心联合开展一项治疗胶质瘤的1期临床试验,探索艾贝司他与替莫唑胺/放疗联用治疗胶质瘤的安全性和有效性。同时,此项研究已向 美国国立卫生研究院(NIH)申请研究经费。
Title: A Phase I Study of Metronomic Temozolomide with PCI-24781 for Patients with Recurrent High Grade Glioma
题目:替莫唑胺化疗与艾贝司他联用治疗复发性高级别胶质瘤的I期临床研究
Objectives: To assess the dose limiting toxicity and efficacy of metronomic temozolomide and PCI-24781 for recurrent high grade glioma patients who have received prior radiation therapy and standard temozolomide.
目的:评估替莫唑胺化疗和艾贝司他联用对既往放射治疗和替莫唑胺标准治疗后复发的高级别胶质瘤患者的剂量限制性毒性和有效性。
脑瘤的发病率仅次于胃、子宫、乳腺及食管肿瘤的发病率,约占全身肿瘤的2%。由于绝大多数抗肿瘤药物(包括PD-1和PD-L1类药)无法有效穿过血脑屏障,治疗脑瘤新药一直没有突破。替莫唑胺和艾贝司他联用有望为脑瘤患者带来新的治疗手段。
