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 first two years after the radiotherapy, but persists for decades. To gain further insight in the radiation-induced leukoencephalopathy, the objective of this project is to study the onset and evolution of leukoencephalopathy in a 3-year prospective cohort of patients having undergone cerebral radiotherapy for glioma (stage 3-4), using specific cognitive tests, Magnetic Resonance Imagery (MRI) scans of the brain and predictive bio-markers of cognitive impairments.
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.
Patients with glioblastoma face a grim prognosis. Despite recent advancement in neurosurgical technology and neuro-oncology glioblastomas almost invariably progress or recur after a median of 4-8 months. The strategy to repeat tumor resection at recurrence in order to minimize tumor load and thus to facilitate subsequent second-line therapy has been shown to be feasible and safe. However, evidence for a survival benefit of surgery for recurrent glioblastoma is scarce and relies entirely on retrospective analyses. While most retrospective analyses report an apparent survival benefit, an EORTC meta-analysis on second-line therapies found no survival difference in patients with or without surgery at recurrence. With regard to the risks and costs inherent to surgery for glioblastoma, a randomized controlled trial is required. The purpose of the study is to compare the effect of craniotomy and tumor resection followed by adjuvant second-line therapy to no surgery followed by second-line therapy on overall survival, neurological status, and quality of life. Analysis of overall survival will be used to improve sample size estimation of a subsequent phase III trial for craniotomy and tumor resection of glioblastoma recurrence in cooperation with the EORTC.
By employing a combination of advanced MRI techniques and correlative serum biomarkers of blood brain barrier (BBB) disruption, the investigators plan to develop a powerful, first of its kind clinical algorithm in pediatrics whereby the investigators can measure and identify the window of maximal BBB disruption post MLA to 1) allow for an alternative to surgery in incompletely resected tumors, 2) allow for optimal chemotherapeutic dosing to achieve the greatest benefits and the least systemic side effects and 3) distinguish subsequent tumor progression from long-term MLA treatment effects. Preliminary data in adult imaging studies have shown that the BBB disruption lasts for several weeks following treatment before returning to a low baseline. This pilot therapeutic study will provide preliminary validation in pediatric patients.
A phase I/II study of pazopanib in combination with temozolomide in patients with newly diagnosed glioblastoma multiforme after surgery and RT-CT (PAZOGLIO study)
This research study is studying a new type of vaccine as a possible treatment for patients with glioblastoma. This research study is a Phase I clinical trial, which tests the safety of an investigational intervention and also tries to define the appropriate dose of the intervention to use for further studies. "Investigational" means that the intervention is being studied and that research doctors are trying to find more about it. It also means that the FDA (U.S. Food and Drug Administration) has not approved the Personalized NeoAntigen Cancer Vaccine for any use in patients, including people with glioblastoma. The purpose of the initial study cohort (Cohort 1) is to determine if it is possible to make and administer safely a vaccine against glioblastoma by using information gained from specific characteristics of the participants tumor. It is known that glioblastomas have mutations (changes in genetic material) that are specific to an individual patient's tumor. These mutations can cause the tumor cells to produce proteins that appear very different from the body's own cells. It is possible that these proteins used in a vaccine may induce strong immune responses, which may help the body fight any tumor cells that could cause the glioblastoma to come back in the future. Three additional cohorts (1a, 1b, & 1c) were added to the study following completion of accrual to the original study cohort (cohort 1). Each new cohort receives NeoVax and radiation therapy as administered to cohort 1 and will also receive pembrolizumab: cohort 1a patients will start pembrolizumab w/in 2 weeks after start of RT, and continue every 3 weeks for up to 2 years; cohort 1b patients will start pembrolizumab 2-4 weeks after completion of NeoVax priming, and continue every 3 weeks for up to 2 years; cohort 1c patients will receive a single dose of pembrolizumab administered within 2 weeks after start of RT, re-start 2-4 weeks after completion of NeoVax priming, and continue every 3 weeks for up to 2 years. The rationale for adding these new cohorts is: 1) to assess the safety and feasibility of NeoVax when administered with pembrolizumab; and 2) to determine if the timing of anti-PD-1 administration impacts the immunogenicity of NeoVax. An additional sub-study cohort (1d) is being added for patients whose tumor is MGMT-methylated. Cohort 1d will enroll patients with tumors for which the MGMT status is methylated or partially methylated; patients on cohort 1d will receive standard daily temozolomide during radiation and as adjuvant therapy for up to six cycles following completion of radiation therapy. The rationale for adding cohort 1d is to determine the safety and feasibility of NeoVax when administered with pembrolizumab and temozolomide.
The high-grade malignant brain tumor glioblastoma multiforme (GBM) comprise the majority of all primary brain tumors in adults. This group of tumors also exhibits the most aggressive behavior, resulting in median overall survival durations of only 9-12 months for GBM. Initial therapy consists of surgical resection, external beam radiation or both. Currently, all patients experience a recurrence after this first-line therapy, so improvements in both first-line and salvage therapy are critical to enhancing quality-of-life and prolonging survival. Superselective Intraarterial Cerebral Infusion (SIACI) is a technique that can effectively increase the concentration of drug delivered to the brain while sparing the body of systemic side effects. This technique threads a tiny catheter through the patient's femoral artery in the leg, up through the body and neck and into the brain. Once the catheter reaches the brain, chemotherapy is released to the blood vessels that feed the tumor.
In this study patients will be treated with 6 weeks of radiation therapy plus temozolomide chemotherapy according to the standard of care. However, the radiation treatment plan will be modified to deliver an higher than routine radiation dose to the subventricular zone which is an area of the brain that contains stem cells that some scientists believe may contribute to glioblastoma recurrence. The purpose of the study is to see if the tumor is controlled for a longer period of time in patients treated with this modified radiation technique than it is in patients treated with standard radiation therapy plus temozolomide chemotherapy.
In this study we propose to determine outcomes of patients age 70 or older treated with radiation over 2 weeks given with temozolomide 75 mg/m2 daily during radiotherapy and as a post radiation treatment of 150 mg/m2 - 200 mg /m2 for 6 cycles or until the disease progresses.
