Study of Neurological Complication After Radiotherapy for High Grade Glioblastoma
The survival time and the number of long time survivors after radiotherapy in brain cancer patients have increased for the last decades. Therefore the topic of late-delayed neurotoxic effects of this therapy gains more and more importance. Among these side effects, the main and most frequent one is the leukoencephalopathy, a diffused and progressive damage of the white matter characterized by myelin loss, loss of axons and vascular lesions. The incidence rate assessment, as well as the occurrence time, is based on retrospective studies with low numbers of patients, but seems to reach 30 to 50 % of the patients according to the follow-up. The risk seems to be increased during the...

Study of Palbociclib in MLL-rearranged Acute Leukemias
Diagnosis: Acute myeloid leukemia; Acute lymphoblastic leukemia Age ≥ 18 years, no upper age limit Study drug: Palbociclib Phase Ib/IIa, open-label - Phase Ib: Based on previous experience with 125 mg palbociclib once daily for 21 days followed by 7 days of rest in patients with breast cancer, liposarcoma, non-small cell lung cancer, hepatocellular carcinoma, ovarian cancer, mantle-cell lymphoma, and glioblastoma, this regimen will be chosen for the first dose to be evaluated in the phase Ib. Based on a 3 + 3 modified Fibonacci design, the tolerable dose of palbociclib for the phase IIa is defined. - Phase IIa: single-agent palbociclib using the...

Study of Prognostic Biomarkers of Survival at 6 Months for Patients Treated With Bevacizumab Glioblastomas in First Relapse After Failure of Radiochemotherapy
No predictive factors are known for the response to the bevacizumab anti-angiogenic molecule (Avastin) given in the event of relapse of glioblastoma (GBM) following radiochemotherapy. Classical MRI with gadolinium injection and perfusion is not sufficient to predict survival and response or duration. We propose to evaluate the prognostic interest for 6-month survival of spectroscopic biomarkers of proliferation, glial reaction, infiltration and glutaminergic metabolism or glycolytic metabolism recorded at 7 and 28 days of application of the treatment. These biomarkers are based on the increase of an index combining choline / Creatine (Cho / Cr), Glx / Cr (Glutamine and glutamate...

Study on Neuroepithelial Tumor Grading and Pseudoprogression After Glioma Therapy Using Advanced Functional MRI Techniques
Contrast-enhanced MRI is the most common way for evaluating neuroepithelial tumor grading and monitoring for tumor recurrence,but the ability to predict tumor behavior remains very limited.In this study, the investigators will use multi-b-value diffusion-weighted imaging(DWI),three-dimensional arterial spin labeling(3D-ASL) and dynamic contrast-enhanced MRI imaging(DCE) to evaluate neuroepithelial tumor grading and monitor for tumor recurrence.

Supra-early Post-Surgery Chemotherapy in the Treatment on GBM Patients
The primary purpose of the study is to evaluate the efficacy and safety of supra-early post-surgery chemotherapy versus standard TEMODAL® regimen in treatment of patients with newly diagnosed glioblastoma multiforme. The secondary purpose is to assess the efficacy of supra-early post-surgery chemotherapy in release brain edema.

Surgery, Radiation Therapy, and Chemotherapy With or Without Photodynamic Therapy in Treating Patients With Newly Diagnosed or Recurrent Malignant Supratentorial Gliomas
RATIONALE: Photodynamic therapy uses light and drugs that make cancer cells more sensitive to light to kill tumor cells. It is not yet known if the addition of photodynamic therapy to combined therapy with surgery, radiation therapy, and chemotherapy is more effective than combined therapy alone for supratentorial gliomas. PURPOSE: Randomized phase III trial to study the effectiveness of surgery, radiation therapy, and chemotherapy with or without photodynamic therapy in treating patients who have newly diagnosed or recurrent malignant supratentorial gliomas.

SUTENT (SUNITINIB, SU11248)in Patients With Recurrent or Progressive Glioblastoma Multiforme
Clinical Part: The objective of this study is to determine the efficacy and safety of SUTENT in patients with recurrent or progressive glioblastoma multiforme.Patients with tissue based diagnosis of intracranial glioblastoma multiforme, above 18 years of age and of both genders, who have a first tumor recurrence or progress after surgery, radiation- and chemotherapy will be included. The hypothesis is that SUTENT will significantly increase the progression free survival rate at 6 months in the study population.

Talazoparib - Carboplatin for Recurrent High-grade Glioma With DDRd
In view of the strong biological rationale of employing PARP inhibition in high grade glioma, the current study purposes testing of talazoparib in a biomarker-enriched group of glioma. Carboplatin will be added to sensitize the tumor to PARP inhibition, and low dose radiation therapy will be applied to increase talazoparib drug penetration through blood-brain barrier. The goal is to estimate the effect size of such combinational treatment approach in recurrent high-grade glioma with DNA damage repair deficiency (dDDR)

Targeting Potassium Channels to Reprogram Glioblastoma Microenvironment: in Vitro and in Vivo Studies
The investigators want to verify the hypothesis that targeting the calcium-activated (KCa3.1) and the voltage-dependent K channel (Kv1.3) could be a valuable therapeutic strategy to reprogram cells of the innate immune system, with the aim to fight glioma, a deadly CNS tumor. The investigators will use murine models of glioma, injecting GL261 cells in the brain of syngeneic C57BL6 mice, to study the effect of K channel inhibition on the activation of microglia (M), macrophages (Mf) and NK cells. The investigators will use M and vesicles released from these cells, re-educated toward an anti-tumor phenotype, to interfere with the vicious circle responsible of uncontrolled tumor...

Temozolomide and Procarbazine With Cilengitide for Patients With Glioblastoma Multiforme Without Methylation of the MGMT Promoter Gene
Cilengitide 2000 mg flat i.v. twice weekly is administered over a period of 18 months without interruption. Starting one week after the initiation of Cilengitide, RTX (60 Gy, 2 Gy per fraction) with concurrent daily temozolomide (60 mg/m2 p.o.) and daily procarbazine (PCB, 50 mg p.o. if BSA < 1.7; 100 mg p.o. if BSA ≥ 1.7) is given over a period of 6 weeks (RTX Monday to Friday, both TMZ and PCB seven days a week). After a break of 4 weeks, adjuvant TMZ (50mg/m2 p.o in first cycle, 60 mg/m2 p.o. in subsequent cycles) and PCB (50 mg p.o. if BSA < 1.7; 100 mg p.o. if BSA ≥ 1.7) are then given daily D1 to 20. This TMZ/PCB cycle is repeated every 28 days over a total period of 6...
