cilengitide, temozolomide, and radiation therapy in treating patients with newly diagnosed glioblastoma and methylated gene promoter status

Conditions: Glioblastoma

Summary: centric is a phase 3 clinical trial assessing efficacy and safety of the investigational integrin inhibitor, cilengitide, in combination with standard treatment versus standard treatment alone in newly diagnosed glioblastoma subjects with a methylated o6-methylguanine-deoxyribonucleic acid methyltransferase (mgmt) gene promoter in the tumor tissue. the mgmt gene promoter is a section of deoxyribonucleic acid (dna) that acts as a controlling element in the expression of mgmt. methylation of the mgmt gene promoter has been found to be a predictive marker for benefit from temozolomide (tmz) treatment.
