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.

Interventions

DRUGCilengitide (2-times weekly)

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.

DRUGcilengitide (5-times weekly)

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.

DRUGTemozolomide

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.

RADIATIONRadiotherapy

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.

Number of Participants With AEs Belonging to Standardized Medical Dictionary for Regulatory Activities (MedDRA) Queries (SMQs) Thromboembolic Events and Hemorrhage With NCI-CTC Toxicity Grade 3 or 4

Thromboembolic events (standardized MedDRA query \[SMQ\]) Grade 3 or 4 AEs encompassed hemiparesis and cerebrovascular accident, pulmonary embolism, and deep vein thrombosis. Thromboembolic events (SMQ) of any grade and of Grade 3 or 4 were generally more frequent in the Cilengitide + Temozolomide/Radiotherapy group than in the Temozolomide/Radiotherapy group but were still in the expected range of this patient population The severity of AEs was assessed according to the National Cancer Institute-Common Toxicity Criteria (NCI-CTCAE) (version 3.0): Grade 1=mild, Grade 2=moderate, Grade 3=severe, Grade 4=life threatening or disabling. Note: Death (Grade 5) was regarded as an outcome.

Time frame: Time from first dose up to 28 days after last dose of study treatment, reported between day of first participant randomized, that is, Jun 2009 until cut-off date (07 Feb 2013)

Population: Safety population included all the participants who received any dose of study treatment that is Cilengitide, Temozolomide or Radiotherapy. According to trial design safety data in trial arms (Cilengitide vs Control) were collected based on different visit frequency and different safety surveillance period.

Plasma Clearance (CL)

The CL for cilengitide was calculated by non-compartmental analysis using the computer program WinNonlin, Version 6.2. Cilengitide plasma concentrations were determined after dosing on Day 1 (single dose) and Day 5 (repeated doses) of Week 1.

Time frame: Days 1 and 5 of Week 1

Population: Only Cilengitide (5-times) + Temozolomide + Radiotherapy group was analyzed for this outcome measure as per planned analysis. Here, 'N' (number of participants analyzed) signifies those participants who were evaluable for this outcome measure.

Progression Free Survival (PFS) Time - Investigator and Independent Read

The PFS time is defined as the duration from randomization to either first observation of progressive disease (PD) or occurrence of death due to any cause. Investigator read is the assessment of all imaging by the treating physician at the local trial site. Independent Read is the assessment of all imaging centrally by an Independent Review Committee (IRC).

Time frame: Time from randomization to disease progression, death or last tumor assessment, reported between day of first participant randomized, that is, Jun 2009 until cut-off date, (07 Feb 2013)

Population: ITT population included all the participants who were randomized to study treatment.
