Filter by:Anti-angiogenic therapy is an important treatment strategy for recurrent glioblastoma. Our previous study provided evidence for a potential benefit of apatinib, a humanized monoclonal antibody against VEGFR-2, when added to temozolomide chemotherapy in patients with recurrent glioblastoma. Some patients showed durable responses and prolonged survival, with recorded survival times of over 30 months in 6.4% patients. However, a subset of patients progressed in 2 months. There is a strong need to better predict and monitor apatinib treatment response to prevent patients from adverse effects of ineffective therapy. In this study, whole genome sequencing and RNA-sequencing of formalin-fixed, paraffin-embedded tumor materials from the participants who received apatinib and temozolomide treatment will be performed to identify the response biomarkers and patients who may benefit most from apatinib, avoiding unnecessary potential toxicity and cost for those who are unlikely to benefit from the drug.
This study aims to analyze the role the of Regorafenib in prolonging the Overall Survival of glioblastoma multiforme patients who progressed after surgery and a first-line chemo-radiotherapy treatment in the setting of "real world life".
The combination of anatomical MRI examination with functional examination of tissue metabolic activity such as FET-PET (PET using the radiotracer - 18F-fluoro-ethyl-tyrosine) is a valuable tool to determine the actual tumor infiltration. The FET-PET examination can be performed using the dual-time point aqusition of FET for exact treatment planning. It has also been proven that using the dual FET-PET method, it is possible to obtain a precise image of the glioblastoma infiltration corresponding to the location and shape of the recurrence, and the tumor volumes in dual FET-PET are significantly larger than in MRI. Moreover, tumor defined in dual FET-PET is different than that of the tumor defined in single FET-PET acquisition. In the DualFETboosT trial we plan to assess the safety and preliminary efficacy of hypofractionated irraditon using simultaneous in-field boost directed on dual FET-PET based tumor volumes for treatment of primary glioblastoma multiforme with concomitant temozolomide.
Increasing preclinical and clinical data have shown that myeloid-derived suppressor cells (MDSCs) may represent a significant driver of immunosuppression in glioblastoma (GBM, grade IV astrocytoma) and a potential mechanism of treatment resistance to chemoradiotherapy. Tadalafil, an FDA-approved drug with inexpensive cost and excellent safety profile, has been shown to effectively reduce MDSCs and restore T-cell activation in the peripheral blood and in the tumor microenvironment. The purpose of this study is to investigate the impact of targeting MDSCs in newly diagnosed IDH-wildtype grade III-IV astrocytoma by combining tadalafil with standard of care radiation therapy (RT) and temozolomide (TMZ).
This clinical trial measures the amount and effect of lidocaine injected into patients with glioblastoma while they are undergoing surgical removal of their brain tumors. Lidocaine is a substance used to relieve pain by blocking signals at the nerve endings in skin. Information gained from this study may help researchers come up with new treatments to help patients with glioblastomas in the future.
This is a phase I trial evaluating the maximum tolerated dose, safety and efficiency of Mesenchymal stem cells into which the suicide gene, cytosine deaminase (CD), injected into the resection cavity of patients with recurrent glioblastoma.
This trial assesses the quality of life in patients with high grade glioma and their caregivers using a questionnaire called the Beacon Patient Related Outcomes Quality of Life (PROQOL). Knowledge gained from this trial may help researchers find out if early integration of palliative care will lead to improvement in quality of life for both patients and caregivers.
Relapsed GBMs have a life expectancy of a few months and re-radiation has proven to be safe in terms of toxicity and effective in increasing OS. One of our studies [Ciammella P, 2013, 8:222] reported a median survival of 9.5 months in patients with recurrent GBM and treated with stereotactic radiotherapy with a total dose of 25 Gy in 5 consecutive sessions, in which the dose was prescribed to 70% isodose with a homogeneous gradient towards the center of the target volume. The identification with functional imaging of specific areas with higher tumor cell density, and the possibility of delivering precisely, thanks to the most advanced therapy units, different doses to the different sub-volumes, can lead to an increase in the maximum dose that can be delivered at the expense of the most aggressive areas (with a greater effect on the tumor), compared to smaller doses in areas with lower signal alteration. This selectivity of the doses should allow an increase in the efficacy of the therapy and therefore a hypothetical increase in local control, compared to a radio-induced toxicity on the surrounding healthy tissues almost comparable to that achieved with the previous hypofractionated treatments [Ciammella P, 2013]. In fact, delivering many high doses to the entire volume would result in an excess of radio-induced necrosis within the irradiated regions with high dose, as well as the impossibility of minimizing the doses on healthy areas and / or on non-neoplastic critical areas keeping them at internal dose ranges related to minimal and acceptable toxicity levels. Since there are no studies providing clear indications on the acute and late toxicity of irradiated healthy tissues that have already been the subject of a first course of radiotherapy (STUPP), the choice of safety is the primary objective of the study.
Objective: In preparation of a randomized controlled trial, the investigators aim to assess pilot data on technical feasibility and safety of laser interstitial thermal therapy (LITT) at Radboud University Medical centre and to assess practical feasibility of a randomized study in patients with primary irresectable glioblastoma, as compared with standard of care. Study design: Prospective randomized pilot study. Randomization stopped (amendment September 2nd, 2021), Study population: 20 patients aged >= 18 with radiologically suspected diagnosis of primary glioblastoma and contra-indication for surgical resection. Intervention: Patients will be randomized to receive either (i) biopsy and LITT (n=10) or (ii) biopsy alone (n=10).
Effective treatments are desperately needed for glioblastoma (GBM) patients. This phase I clinical trial assesses the safety of a novel personalized dendritic-cell vaccine administered to GBM patients shortly after completing standard-of-care treatments. Secondary outcomes will evaluate patient progression-free survival and overall survival.
