Enzastaurin, a potent inhibitor of protein kinase C-beta, inhibits angiogenesis and has direct cytotoxic activity against glioma cells in preclinical studies. Patients with recurrent high-grade gliomas were stratified by histology and use of enzyme-inducing antiepileptic drugs (EIAEDs). Patients on EIAED were treated on the phase I dose-escalation portion(More)
PURPOSE Enzastaurin is a selective inhibitor of protein kinase C beta. Prior phase I studies did not show increased drug exposures with escalating once daily administration. Limits from gastrointestinal absorption may be overcome by twice daily dosing, potentially improving antitumor effects. EXPERIMENTAL DESIGN We conducted a phase I dose escalation(More)
Bevacizumab ((BEV) has become a mainstay of treating recurrent glioblastoma, but eventual tumor resistance is expected. Targeting multiple growth-associated signaling pathways may result in more effective treatment than targeting VEGF alone. Patients with recurrent glioblastoma were stratified by prior BEV exposure and treated with sunitinib 37.5 mg daily(More)
We evaluated the efficacy of combination enzastaurin (LY317615) and bevacizumab for recurrent malignant gliomas and explored serologic correlates. We enrolled 81 patients with glioblastomas (GBM, n = 40) and anaplastic gliomas (AG, n = 41). Patients received enzastaurin as a loading dose of 1125 mg, followed by 500 or 875 mg daily for patients on(More)
The purpose of this study was to evaluate the activity of single-agent bevacizumab in patients with recurrent anaplastic glioma and assess correlative advanced imaging parameters. Patients with recurrent anaplastic glioma were treated with bevacizumab 10 mg/kg every 2 weeks. Complete patient evaluations were repeated every 4 weeks. Correlative dynamic(More)
Twenty-two patients with recurrent glioblastoma (GBM) were prospectively treated with everolimus and gefitinib, designed to test the combined inhibition of mammalian target of rapamycin (mTOR) and epidermal growth factor receptor (EGFR) as part of a larger clinical trial. The primary endpoint was radiographic response rate. Secondary endpoints included(More)
Vandetanib is a once-daily multitargeted tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2, epidermal growth factor receptor, and the rearranged-during-transfection oncogene. A phase I trial was conducted to describe the pharmacokinetics of vandetanib in patients with recurrent glioma on enzyme-inducing anti-epileptic drugs (EIAEDs)(More)
BACKGROUND Primary brain tumor patients are at increased risk for stroke from disease and treatment-specific mechanisms. METHODS We conducted a retrospective review of patients with primary brain tumors diagnosed with MRI-confirmed ischemic stroke between 1996 and 2006. Data were collected including risk factors, diagnostic workup, and treatment for(More)
NF-kB inhibition by bortezomib enhances tamoxifen-induced apoptosis in preclinical glioma models. We conducted a single institution, phase II trial to evaluate efficacy and safety of high dose tamoxifen with bortezomib in adults with recurrent malignant gliomas. The primary endpoint was radiographic response. Concurrent enzyme inducing anticonvulsants and(More)
Bevacizumab, a monoclonal antibody against vascular endothelial growth factor (VEGF), recently received FDA approval for recurrent glioblastoma. Additionally, several VEGF receptor (VEGFR) tyrosine kinase inhibitors (TKIs) have entered trials for recurrent glioma. Phase II studies of bevacizumab for recurrent GBM have reported incidents of ischemic stroke(More)
