Conditions: Glioblastoma
Keywords: Newly diagnosed Glioblastoma (WHO Grade IV) Cilengitide Temozolomide Radiotherapy
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 265
Healthy volunteers: no

Brief summary:
CORE is a Phase 2 clinical trial in newly diagnosed glioblastoma in subjects with an unmethylated 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 appear to be a predictive marker for benefit from temozolomide (TMZ) treatment.

In a safety run-in period in dedicated study centers, the safety and tolerability of Cilengitide given as an intense treatment in combination with the first part of standard therapy will be assessed. Thereafter the trial will investigate the overall survival and progression-free survival in subjects receiving two different regimens of Cilengitide in combination with standard treatment versus standard treatment alone.

Detailed description:

Arms:
arm 1: None arm 2: None arm 3: None

Interventions: intervention 1: Cilengitide (2-times weekly) intervention 2: cilengitide (5-times weekly) intervention 3: Temozolomide intervention 4: Radiotherapy
Intervention descriptions: intervention 1: Cilengitide 2000 milligram (mg) will be administered intravenously twice weekly over 1 hour infusion from Weeks -1 to 77 or until occurrence of progressive disease, unacceptable toxicity, or withdrawal for any other reason. If considered beneficial in the opinion of the Investigator, continuation of cilengitide treatment will be optional in subjects without disease progression and after Week 77 since start of treatment. intervention 2: Cilengitide 2000 milligram (mg) will be administered intravenously 5-times weekly over 1 hour infusion from Weeks -1 to 77 or until occurrence of progressive disease, unacceptable toxicity, or withdrawal for any other reason. If considered beneficial in the opinion of the Investigator, continuation of cilengitide treatment will be optional in subjects without disease progression and after Week 77 since start of treatment. intervention 3: Temozolomide (TMZ) 75 milligram per square meter \[mg/m\^2\] will be administered intravenously once daily from Week 1 to 6. From Week 11 onwards, TMZ will be given as maintenance treatment at a dose of 150-200 mg/m\^2 for consecutive 5 days every 4 weeks until Week 34 or until disease progression. intervention 4: Radiation therapy (RTX) at a dose of 2 gray (Gy) per fraction will be given once daily, 5 days per week from Week 1 to 6, total dose 60 Gy.
