Filter by:This is non-randomized phase 2 study to assess efficacy and toxicity of long term high dose vitamin D3 given concurrently with chemo-radiotherapy (CCRT) containing temozolomide followed by adjuvant chemotherapy (ACT) with temozolomide in patients with newly diagnosed glioblastoma multiforme GBM). Preoperative diagnosis of GBM will be based on magnetic resonance imaging (MRI) brain scan. All patient will underwent craniotomy with partial or total resection of a visible tumour mass. All patients will be planned for postoperative three-dimensional conformal RT (3-DCRT) or intensity-modulated RT (IMRT) to residual tumour and/or resection bed. A total RT dose of 54-60 Gy will be delivered using 2 Gy daily fractions given over 5 days a week. Daily chemotherapy with temozolomide in the dose of 75 mg/m2/day will be started at the first day of RT, and will be continued for entire period of RT inclusive week-end breaks. ACT will contain 6 cycles of oral temozolomide 150-200 mg/m2/day given for 5 days every 4 weeks. Oral vitamin D3 will be administered in daily dose of 4000 IU. Vitamin D3 therapy will be started 1 week prior to commencing CCRT, and will be terminated immediately after completing last cycle of ACT. MRI scan of the brain will be performed at 4 months after completing CCRT, and than will be repeated every 4 months for first 2 years, and every 6 months for subsequent years. The study participants will be followed until disease progression or death. The study is expected to complete within 4 years.
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 cycles.
Standard treatment for glioblastomas includes radiation and chemotherapy with a drug called temozolomide (Temodar); however, glioblastomas frequently develop resistance to standard treatment and recur or progress. Glioblastomas are known to have decreased levels of oxygen compared to normal tissues. There is evidence that these lower oxygen levels in glioblastomas may contribute to their ability to resist treatment effects of radiation and chemotherapy. In this study we will look to increase the oxygen concentration within the glioblastoma by adding hyperbaric treatments (the experimental part of this study) to standard treatment with radiation and temozolomide in order to see whether increasing the oxygen concentration within the tumor increases the tumor-killing ability of standard radiation and chemotherapy. In addition, the investigators are interested to evaluate the effect of this treatment protocol on a person's quality of life and level of stress, and, therefore, the investigators will ask subjects to complete several brief questionnaires while they are on-study.
The purpose of this study is to establish a Brain and Spinal Tumor Tissue/Specimen repository to serve as a resource for current and future scientific studies.
This study will test the hypothesis that prolonged adjuvant Temozolomide (TMZ) may delay relapses in patients with glioblastoma compared to the standard care consisting in observation with brain MRI every 3 months and rechallenging with TMZ at relapse (Stop and Go arm).
Phase 1b of the study, will evaluate the safety and tolerability of AQ4N treatment at three different dose levels. Phase 2a of the study, will further evaluate the safety, tolerability, and in addition efficacy of AQ4N treatment at a tolerated dose selected from Phase 1b.
GERT is a one-armed single-center phase I/II trial. In a first step, dose-escalation of TMZ from 50 mg/m2 to 75mg/m2 together with radiotherapy and cetuximab will be performed. Should safety be proven, the phase II trial will be initiated with the standard dose of 75mg/m2 of TMZ. Cetuximab will be applied in the standard application dose of 400mg/m2 in week 1, thereafter at a dose of 250mg/m2 weekly. A total of 46 patients will be included into this phase I/II trial. Primary endpoints are feasibility and toxicity, secondary endpoints are overall and progression-free survival. An interim analysis will be performed after inclusion of 15 patients into the main study. Patients’ enrolment will be performed over a period of 2 years. The observation time will end 2 years after inclusion of the last patient.
This study will collect blood and urine samples from patients undergoing radiation therapy for glioblastoma multiforme (a type of brain tumor) to investigate the effects of this treatment on blood cells and certain proteins. The information from this study may help scientists develop new tests to measure radiation exposure and find new ways to treat cancer with radiation, and help determine which kinds of patients or tumors respond better to radiation therapy. Two proteins of particular interest in this study and which may be involved in the recurrence of cancer are VEGF (vascular endothelial growth factor) and MMPs (matrix metalloproteinases). Patients 18 years of age and older with glioblastoma multiforme who are receiving or will receive radiation therapy as part of their medical treatment may be eligible for this study. Candidates are screened with a history and physical examination, blood tests, and magnetic resonance imaging (MRI) of the brain. Participants will have blood and urine samples collected before, during and after completion of their radiation treatment. Urine samples are collected in a cup and about 2 tablespoons of blood are withdrawn through a needle in a vein. Additional samples may be requested at different times during treatment and in the 3-year follow-up period.
RATIONALE: Erlotinib may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth. PURPOSE: Phase II trial to study the effectiveness of erlotinib in treating patients who have recurrent or progressive glioblastoma multiforme.
