DelMar是一家专注于开发实体瘤癌症疗法的生物制药公司,近日宣布已注册并开始VAL-083II临床研究,VAL-083旨在一线治疗MGMT未甲基化的胶质母细胞瘤(GBM)。该试验正在中国广州的中山大学癌症中心(SYSUCC)进行,计划招募多达30例患者,以确定VAL-083能否改善GBM患者的无进展生存期(PFS)。

DNA修复蛋白O6-甲基鸟嘌呤-DNA甲基转移酶(O6-methylguanine-DNA methyltransferaseMGMT)启动子甲基化是胶质瘤患者的重要分子标志物,与胶质瘤预后及烷化剂耐药有关。而对于MGMT未甲基化的胶质母细胞瘤(GBM),其MGMT基因的转录水平较高,理论上,此类患者对烷化剂耐药程度较高,亟需新型药物。VAL-083(二氢半乳糖醇)是一种双功能DNA靶向剂,可在鸟嘌呤的N7位引入链间DNA交联,导致DNA双链断裂和癌细胞死亡。
