Cilengitide, Temozolomide, and Radiation Therapy in Treating Patients With Newly Diagnosed Glioblastoma and Methylated Gene Promoter Status

Phase 3

Completed

• Conditions: Glioblastoma
• Interventions: Drug: Cilengitide; Drug: Temozolomide; Radiation: Radiotherapy

• Registration Number: NCT00689221
• Lead Sponsor: EMD Serono

Brief 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.

Primary Outcome Measures

Name	Time	Method
Overall Survival (OS) Time	Time from randomization to death or last day known to be alive, reported between day of first participant randomized, that is, Sep 2008 until cut-off date, (19 Nov 2012)	The OS time is defined as the time (in months) from randomization to death or last day known to be alive. Participants without event are censored at the last date known to be alive or at the clinical cut-off date, whatever is earlier.

Secondary Outcome Measures

Name	Time	Method
Time to Maximum Plasma Concentration (Tmax)	Day 1 of Week -1	The Tmax for cilengitide was calculated by non-compartmental analysis using the computer program WinNonlin, Version 6.2.1.
Area Under the Plasma Concentration Curve From Time 0 to 6 Hours (AUC [0-6]) After Dose	Day 1 of Week -1	The AUC (0-6) for cilengitide was calculated by non-compartmental analysis using the computer program WinNonlin, Version 6.2.1.
European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) Sub-scale Scores	Up to 50 months	The EORTC QLQ-C30 is a questionnaire including following sub-scales: global health status, functional scales (physical functioning, role functioning, emotional functioning, cognitive functioning, and social activity), symptom scales (fatigue, nausea and vomiting, and pain) and single items (dyspnoea, insomnia, appetite loss, constipation, diarrhoea and financial difficulties). Scores are averaged for each scale and transformed to 0-100 scale; higher score indicates better quality of life on global health status and functional scales and worse quality of life on symptom scales and financial difficulty scale.
Maximum Observed Plasma Concentration (Cmax)	Day 1 of Week -1	The Cmax for cilengitide was calculated by non-compartmental analysis using the computer program WinNonlin, Version 6.2.1.
European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Brain Module (EORTC QLQ-BN20) Sub-scale Scores	Up to 50 months	The QLQ-BN20 is a questionnaire specifically designed as the QLQ-C30 supplement for the evaluation of quality of life in brain tumor participants. It includes 4 multi-item sub-scales: future uncertainty, visual disorder, motor dysfunction, communication deficits, and 7 single-item scales: headaches, seizures, drowsiness, itchy skin, hair loss, weakness of legs, and bladder control. All items are rated on a 4-point Likert-type scale ('1=not at all', '2=a little', '3=quite a bit' and '4=very much'), and are linearly transformed to a 0-100 scale, with higher scores indicating more severe symptoms.
Number of Participants With Adverse Events (AEs), Serious AEs, Treatment-Related AEs, Treatment-Related Serious AEs, AEs Leading to Death, Treatment Related AEs Leading to Death, AEs of Grade 3 or 4 and Treatment Related AEs of Grade 3 or 4	Time from first dose up to 28 days after last dose of study treatment, reported between day of first participant randomized, that is, Sep 2008 until cut-off date (19 Nov 2012)	An AE is defined as any new untoward medical occurrences/worsening of pre-existing medical condition without regard to possibility of causal relationship. Treatment-emergent AEs are the events between first dose of study drug and up to 28 days after last dose of study treatment. A Serious AE is an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect. Treatment-related AEs are the AEs which are suspected to be reasonably related to the study treatment (cilengitide, or radiotherapy, or temozolomide) as per investigator assessment. 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.
Number of Participants With Change From Baseline in Work Status at End of Study	Baseline, End of study (up to cut-off date, [19 Nov 2012])	Number of participants with change from baseline in work status (working full time \[FT\], part-time \[PT\], unemployed/retired \[U/R\]) at end of study (EOS) (up to cut-off date, \[19 Nov 2012\]) was reported. For the category 'part-time', the following sub-categories were defined: part-time due to basic disease (PT1); part-time not due to basic disease (PT2); part-time reason not known (PT3).
Progression Free Survival (PFS) Time - Investigator and Independent Read	Time from randomization to disease progression, death or last tumor assessment, reported between day of first participant randomized, that is, Sep 2008 until cut-off date, (19 Nov 2012)	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 and Independent Read is the assessment of all imaging centrally by an Independent Review Committee (IRC). Investigator's assessed progression according to MacDonald criteria and IRC by Response Assessment in Neuro-Oncology Working Group (RANO) criteria using Gadolinium-enhanced magnetic resonance imaging.; Investigator and IRC read: Progression is defined as greater than 25 percent increase in the sum of the product of the largest perpendicular diameters of enhancing tumor compared to the smallest prior sum, or Worsening of an evaluable lesion(s),or Marked increase in T2/FLAIR non-enhancing lesions (IRC only) or Any new lesion
EuroQol 5-Dimensions (EQ-5D) Questionnaire Index	Up to 50 months	The EuroQuol-5D (EQ-5D) questionnaire is a measure of health status that provides a simple descriptive profile and a single index value. The optional part of the questionnaire was not applied. The EQ-5D defines health in terms of mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The 5 items are combined to generate health profiles. These profiles were converted to a continuous single index score using a one to one matching. The lowest possible score is -0.594 (death) and the highest is 1.00 (full health).
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	Time from first dose up to 28 days after last dose of study treatment, reported between day of first participant randomized, that is, Sep 2008 until cut-off date (19 Nov 2012)	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.
Number of Participants With Clinically Significant Abnormal Electrocardiogram (ECG) and Lab Parameters	Up to 50 months
