Primary objective:
To estimate 6-month progression free survival probability of pts w recurrent malignant gliomas treated w erlotinib + bevacizumab.
Secondary Objectives:
To evaluate safety & tolerability of erlotinib + bevacizumab among pts w recurrent malignant gliomas To evaluate radiographic response of pts w recurrent malignant gliomas treated w erlotinib + bevacizumab To evaluate pharmacokinetics of erlotinib when administered to pts w recurrent malignant gliomas; & to examine relationship of clinical response to Epidermal Growth Factor (EGFR) expression, amplification, & v-III mutation, phosphatase and tensin homolog (PTEN) expression, vascular endothelial growth factor (VEGF) expression, vascular endothelial growth factor receptor 2 (VEGFR-2) & phosphorylated protein kinase B (PKB/Akt) in archival tumor samples

Glioblastoma Gliosarcoma | Drug: Bevacizumab and Erlotinib | Phase 2 |
Exploratory, Phase II study designed to assess anti-tumor activity of combinatorial regimen consisting of erlotinib + bevacizumab among pts w recurrent malignant glioma. Signal transduction inhibitors, such as erlotinib, as well as anti-angiogenic agents, such as bevacizumab, are expected to exert a cytostatic anti-tumor effect. Primary endpoint of study is probability of progression-free survival at 6 months. An important secondary objective is to further assess the safety of erlotinib + bevacizumab for pts w RMG. Pharmacokinetic studies included in protocol will evaluate impact of enzyme-inducing anti-epileptic drugs (EIAEDs) on metabolism of erlotinib.
If study demonstrates that combo regimen of erlotinib + bevacizumab is associated w encouraging anti-tumor activity among pts w recurrent malignant glioma (RMG), further assessment of regimen in additional ph II & possibly ph III studies, will be considered.

Experimental: Bevacizumab + Erlotinib
Bevacizumab + Erlotinib
|
Drug: Bevacizumab and Erlotinib
Bevacizumab administered intravenously at dose 10 mg/kg every 2 wks. Erlotinib administered orally, continuously once daily in fasting state for each 42-day cycle. Dose of erlotinib is based on prior erlotinib monotherapy trial in RMG. It will be 200 mg/day for pts not on cytochrome P450 3A4 (CYP3A4)-enzyme inducing anti-epileptic drugs & 500 mg/day for pts on EIAEDs. It is possible that taking erlotinib w regular medications or supplements may change how erlotinib, subject's regular medications, or subject's regular supplements work. Treatment will continue until either evidence of progressive disease, unacceptable toxicity, non-compliance w study follow-up, or withdrawal of consent. Other Names:
|
- 6 Month Progression-free Survival [ Time Frame: 6 months ]The proportion of patients alive and progression free at 6 months
- Radiographic Response [ Time Frame: Patients were followed for the duration of the study, with a median follow-up of 103 weeks for grade III participants and 141.8 weeks for grade IV participants ]
The number of participants with complete or partial response as determined by the following criteria:
- Complete response (CR): Disappearance of all enhancing tumor on contrast enhanced MRI scan. Patient must be off steroids or only on adrenal maintenance doses.
- Partial response (PR): Greater than or equal to a 50% reduction in the size (products of the largest perpendicular diameters) for all enhancing lesions. No new lesions may arise. Steroids must be stable or decreasing dose.
- Pharmacokinetics of Erlotinib: Cmax [ Time Frame: Day 1 and 42 of Dosing Erlotinib ]Day 1 and Day 42 of Dosing Erlotinib in Cycle 1: Maximum Concentration (ng/mL) (Cmax) for subjects receiving 500 mg (Enzyme-Inducing Anti-epileptic Drug, EIAED) or 200 mg (non-EIAED) Erlotinib
- Pharmacokinetics of Erlotinib: AUC [ Time Frame: Day 1 and 42 of Dosing Erlotinib ]Day 1 and Day 42 of Dosing Erlotinib in Cycle 1: Area under the Curve (ng/mL.h) (AUC) for subjects receiving 500 mg (Enzyme-Inducing Anti-epileptic Drug, EIAED) or 200 mg (non-EIAED) Erlotinib
- Association of Biomarkers and One-year Survival - Epidermal Growth Factor (EGFR) [ Time Frame: 1 year ]Archival tumor samples from grade IV participants were examined by immunohistochemistry for biomarkers.
- Association of Biomarkers and One-year Survival - EGFR vIII [ Time Frame: 1 year ]Archival tumor samples from grade IV participants were examined by immunohistochemistry for biomarkers.
- Association of Biomarkers and One-year Survival - Phosphatase and Tensin Homologue (PTEN) [ Time Frame: 1 year ]Archival tumor samples from grade IV participants were examined by immunohistochemistry for biomarkers.
- Association of Biomarkers and One-year Survival - Phosphorylated Protein Kinase B (pAKT) [ Time Frame: 1 year ]Archival tumor samples from grade IV participants were examined by immunohistochemistry for biomarkers.
- Association of Biomarkers and One-year Survival - Phosphorylated Mitogen-activated Protein Kinase (pMAPK) [ Time Frame: 1 year ]Archival tumor samples from grade IV participants were examined by immunohistochemistry for biomarkers.
- Association of Biomarkers and One-year Survival - Vascular Endothelial Growth Factor (VEGF) [ Time Frame: 1 year ]Archival tumor samples from grade IV participants were examined by immunohistochemistry (IHC) for biomarkers. The IHC expression score is the product of the percentage of cancer cells positive for VEGF multiplied by the overall intensity of staining, ranging from 0 to 3+. This produces a score ranging from 0 to 300.
- Association of Biomarkers and One-year Survival - VEGFR-2 [ Time Frame: 1 year ]Archival tumor samples from grade IV participants were examined by immunohistochemistry (IHC) for biomarkers. The IHC score is the product of the percentage of cancer cells positive for VEGFR-2 multiplied by the overall intensity of staining, ranging from 0 to 3+. This produces a score ranging from 0 to 300.
