Retrospective Evaluation of Melanocortin Receptor 4 Polymorphisms in Patients With GBM Treated With Radiochemotherapy
Glioblastoma (GBM) accounts for approximately 50% of all glioma and among these tumors, are the most malignant. The cells of origin of glioma are still undefined, but the most putative target cells include astrocytes, neural stem cells, and oligodendrocyte precursor cells. The current standard of care for patients with newly diagnosed GBM includes temozolomide and radiotherapy . Melanocortins are peptides with well-recognized anti-inflammatory and neuroprotective activity. Of the five known melanocortin receptors (MCRs), only subtype 4 is present in astrocytes and it is expressed predominantly in the brain. No data are currently available on MC4R gene polymorphisms and gliomas or...

Risk Factors for Developing a Blood Clot in Patients Who Are Undergoing Cancer Treatment for Newly Diagnosed Gliomas
RATIONALE: Patients with gliomas may be at risk for developing blood clots. Learning about the risk factors for developing blood clots may help doctors plan better treatment for gliomas. PURPOSE: This clinical trial is studying risk factors for developing blood clots in patients who are undergoing cancer treatment for newly diagnosed gliomas.

RO4929097, Temozolomide, and Radiation Therapy in Treating Patients With Newly Diagnosed Malignant Glioma
This phase I trial studies the side effects and best dose of gamma-secretase/Notch signalling pathway inhibitor RO4929097 (RO4929097) when given together with temozolomide and radiation therapy in treating patients with newly diagnosed malignant glioma. Enzyme inhibitors, such as gamma-secretase/Notch signalling pathway inhibitor RO4929097, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill...

RRx-001 + Radiation + Temozolomide In Newly Diagnosed Glioblastoma and Anaplastic Gliomas
This is a two-part Phase I add-on clinical trial in newly diagnosed glioblastoma or GBM. By "add-on" what is meant is that the experimental intravenous therapy, RRx-001, is combined or "added on" to standard of care. In newly diagnosed GBM standard of care consists of radiotherapy + temozolomide (TMZ) for 6 weeks followed (after a 4-6 weeks break) by maintenance TMZ given until the tumor progresses or worsens. By "maintenance" therapy what is meant is that TMZ is given less frequently to prolong or extend the time during which the tumor remains stable. G-FORCE-1 will be conducted in two parts; in the first part of the study (Dose Escalation, Part A) patients will be entered or...

RT, Temozolomide, and Bevacizumab Followed by Bevacizumab/Everolimus in First-line Treatment of GBM
In this phase II trial the investigators plan to incorporate two targeted agents, bevacizumab and everolimus, into the first-line multimodality therapy of glioblastoma. In the first portion of the treatment, bevacizumab will be added to standard concurrent radiation therapy plus temozolomide. After completing radiation therapy, patients will continue treatment with the combination of bevacizumab and everolimus.

S0001 RT and Carmustine With or Without O6BG in Patients With New Glioblastoma Multiforme or Gliosarcoma
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. O6-benzylguanine may help carmustine kill more tumor cells by making tumor cells more sensitive to the drug. It is not yet known whether radiation therapy and carmustine are more effective with or without O6-benzylguanine. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy plus carmustine with or without O6-benzylguanine in treating patients who have newly diagnosed glioblastoma multiforme or gliosarcoma.

Safe Study of Dendritic Cell (DC) Based Therapy Targeting Tumor Stem Cells in Glioblastoma
The study induces an immune response towards the stem-cell like part of glioblastomas in combination with standard therapy. The aim is to define and characterize the feasibility, potential adverse effects of such therapy and measure time to progression and survival.

Safety and Clinical Activity of Lapatinib in Patients With HER2-positive Refractory Advanced Cancer
Although anti-HER2 (human epidermal growth factor receptor 2) therapy is currently approved for breast, gastric, and gastroesophageal cancers overexpressing the HER2 protein or amplified for the HER2 gene, HER2 aberrations (gene amplification, gene mutations, and protein overexpression) are reported in other diverse malignancies. Indeed, about 1-37% of tumors of the following types harbor HER2 aberrations: bladder, cervix, colon, endometrium, germ cell, glioblastoma, head and neck, liver, lung, ovarian, pancreas, and salivary duct. Lapatinib is an orally active, reversible, small molecule TKI that potently inhibits both ErbB1 and ErbB2 tyrosine kinase activity. Data suggest that...

Safety and Effectiveness Study of G207, a Tumor-Killing Virus, in Patients With Recurrent Brain Cancer
This clinical trial will study the safety and effectiveness of an engineered herpes virus, G207, administered directly into the brain of patients with recurrent brain cancer. G207 has been modified from the herpes virus that causes cold sores (called herpes simplex virus type 1 or HSV-1). G207 has been designed so that it should kill tumor cells, but not harm normal brain cells. G207 has been shown to be safe in animal testing completed to date and in previous studies in patients with brain tumors. This is a phase Ib/II study. In the phase Ib portion of the study, patients will receive G207 at a dose that is higher than tested in previous human studies. Patients will initially...

Safety and Efficacy of PF-299804 (Dacomitinib), a Pan-HER Irreversible Inhibitor, in Patients With Recurrent Glioblastoma With EGFR Amplification or Presence of EGFRvIII Mutation. A Phase II CT.
This multicenter, 2-stage, open-label, phase II trial aims to assess the efficacy and safety of dacomitinib in adult patients with recurrent Glioblastoma (GBM) with EGFR gene amplification and/or EGFRvIII mutation.
