Predictive Values of Preoperative [68Ga]Ga-PSMA-11 PET/CT in Patients With Suspected Brain Tumours of Glial Origin
The aim of this study was to analyse usefulness of [68Ga]Ga-PSMA-11 PET/CT scans in preoperative differentiation between HGG and LGG in patients with suspicion of a tumor of glial origin in previously performed imaging examinations. The PET/CT scan will be compared with postoperative histopathological results and with additional immunohistochemical staining for PSMA expression.

Preoperative Ceritinib (LDK378) in Glioblastoma Multiforme and CNS Metastasis
This is two parallel studies to examine pharmacokinetic (PK), pharmacodynamic (PD), and pharmacogenetic (PG) endpoints following short-interval therapy (10-14) daily doses without dose reduction and interruption) with the ALK (anaplastic lymphoma kinase) small-molecule inhibitor, ceritinib. The Phase 0 study will investigate: 1. first recurrence GBM patients and 2. patients with CNS metastases from solid tumors such as, but not limited to, NSCLC (non-small cell lung cancer) and melanoma. The CNS (central nervous system) metastases Phase 0 is designed to identify PK effects (in addition to PD, and PG effects on ALK-positive NSCLC metastases), while the GBM...

Pre-operative IL13-PE38QQR in Patients With Recurrent or Progressive Malignant Glioma
IL13-PE38QQR is an oncology drug product consisting of IL13 (interleukin-13) and PE38QQR (a bacteria toxin). IL13-PE38QQR is a protein that exhibits cell killing activity against a variety of IL13 receptor-positive tumor cell lines indicating that it may show a therapeutic benefit. In reciprocal competition experiments, the interaction between IL13-PE38QQR and the IL13 receptors was shown to be highly specific for human glioma cells. Prior to treatment, patients will have physical and neurologic exams, MRI to measure the extent of tumor, tumor biopsy, and screening laboratory tests. On Day 1, one or two catheters will be inserted directly into the tumor, after which a CT scan...

Prinomastat Plus Temozolomide Following Radiation Therapy in Treating Patients With Newly Diagnosed Glioblastoma Multiforme
RATIONALE: Prinomastat may stop the growth of glioblastoma multiforme by stopping blood flow to the tumor. Drugs used in chemotherapy stop tumor cells from dividing so they stop growing or die. PURPOSE: Randomized phase II trial to study the effectiveness of prinomastat plus temozolomide in treating patients who have newly diagnosed glioblastoma multiforme.

Procarbazine in Treating Patients With Recurrent Brain Tumor
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I/II trial to study the effectiveness of procarbazine in treating patients who have progressive or recurrent astrocytoma, oligodendroglioma, or glioblastoma multiforme following treatment with radiation therapy.

Progesterone Induced Blocking Factor Expression Levels in Endometrial Cancer Cells.
Immune system suppression effect of Progesterone Induced Blocking Factor(PIBF), it could be questionable whether tumor cells express PIBF for escape of immune system. There are some studies in the literature that evaluate PIBF expression of different malign cells (e.g. glioblastoma multiforme as a malign central nerve system, leukemia, astrocytoma as a primary brain tumor, lung cancer and chorionic carcinoma). According to previous studies PIBF has been used as an anti-tumor immune suppressor by tumor cells. There is no data about the PIBF expression of endometrial tumor cells. Therefore, the investigators aim to determine the PIBF expression levels in the endometrial cancer cells.

Prospective Phase 2 Trial of Cabazitaxel in Patients With Temozolomide Refractory Glioblastoma Multiforme
The proposed study is an open-label, single-arm, Phase- II trial to assess the efficacy of cabazitaxel in GBM WHO grade IV patients with a progression during or within 6 months after last temozolomide treatment (Figure 1). Cabazitaxel will be given at a dose of 25mg/m² as 1h infusion every 3 weeks with standard concomitant medication (as outlined below): - On Day 1 of each cycle, patients will receive cabazitaxel at a dose of 25mg/m², administered by i.v. route in 1 hour. - Cycle length for cabazitaxel is 3 weeks (21 days). - New cycles of therapy may not begin until Absolute Neutrophil Count (ANC) ≥1500/mm3, platelet count ≥75 000/mm3, and...

Protein Phosphatase 2A Inhibitor, in Recurrent Glioblastoma
Background: The brain is separated from the rest of the blood stream by the blood-brain barrier. This is like a filter that protects the brain. But is also a challenge when medicines need to get into the brain. Researchers want to give the new drug LB100 to people before brain tumor surgery. They will measure how much LB100 is in the blood and how much gets into the brain. This may help with the use of LB100 to treat brain tumors in the future. Objective: To see if LB100 can pass into the brain. Eligibility: People at least 18 years old with a brain tumor that requires surgery. Design: Participants will be screened with: Physical exam Medical...

PTK787/ZK 222584 in Combination With Temozolomide and Radiation in Patients With Glioblastoma Taking Enzyme-Inducing Anti-Epileptic Drugs
PTK is an investigational new drug that has been shown in early laboratory studies to prevent the formation of new blood vessels that allow the tumor to grow. These studies have shown that the study drug can potentially improve the effectiveness of additional radiation and chemotherapy. With this study, we would like to examine the effects of PTK when used in combination with radiation therapy and the anti-cancer drug temozolomide, the standard treatment for patients with newly diagnosed glioblastoma. We would also like to learn how the study drug is absorbed, distributed, and cleared from the body.
