Filter by:PreOperative Brain Irradiation in Glioblastoma (POBIG) is a phase I study that will test the safety and feasibility of a single fraction of preoperative radiotherapy in patients with a new radiological diagnosis of glioblastoma (GBM). After the single fraction of radiotherapy, patients will receive standard treatment. The standard treatment consists of resection of the tumor followed by (chemo)radiation (i.e. radiotherapy +/- daily temozolomide (75mg/m2) for 6 weeks (60Gy/30fr) or for 3 weeks (40Gy/15fr)).
Temozolomide (TMZ) is an oral chemotherapy drug. It is an alkylating agent used as a first-line treatment for glioblastoma. This methylation damages the DNA and triggers the death of tumor cells. According to the results of several clinical studies, TMZ synchronous plus radiotherapy and subsequent as adjuvant therapy can significantly improve the survival rate of newly diagnosed glioblastoma patients.
Open, randomized study of a trivalent dendritic cell therapy compared to standard therapy in primary treated patients with IDH wild-type, MGMT-promotor methylated glioblastoma. The IMP is dendritic cells transfected with mRNA of survivin, hTERT og autologous tumor stem cells derived from tumorspheres.
Glioblastoma is the primary brain tumour with the worst prognosis: median survival is only 12 months despite the use of the most advanced treatments. In the past 10 years, survival in the treatment of this disease has not advanced significantly, with the postoperative standard being the administration of chemoradiotherapy with temozolomide, followed by 6 cycles of sequential chemotherapy with temozolomide. Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) have shown a clear synergistic antitumour effect with temozolomide and radiotherapy in preclinical glioma models. THC and CBD have a wide variety of biological effects by binding with and activating the type 1 and type 2 cannabinoid receptors (CB1 expressed in certain neuronal areas of the brain and CB2 expressed in the immune system and in glial cells). The activation of these receptors initiates a signalling pathway, called the endoplasmic reticulum stress response, which generates tumour cell autophagy by activating TRB3. Given these data, the Spanish Group for Neuro-oncology (GEINO) proposes developing a phase Ib, open-label, multicenter, intrapatient dose-escalation clinical trial to assess the safety profile of the THC+CBD combination at a 1:1 ratio, adding temozolomide and radiotherapy in patients with newly-diagnosed glioblastoma. The number of patients to be recruited is 30 over 6 months at 8 sites specialising in neuro-oncology.
Glioblastoma is the most frequent and aggressive primary brain tumor in adults. A team recently showed that baseline plasma levels of matrix metalloproteinase-2 (MMP2) and matrix metalloproteinase-9 (MMP9) were correlated to bevacizumab activity in patients with recurrent glioblastoma. To date, the biological rationale of this results remains unknown but MMP2 could be involved in classical angiogenesis while MMP9 could promote vasculogenesis. The objectives are to correlate the plasma levels of MMP2 and MMP9 to their Ribonucleic acid (RNA) and protein tissue expression, activity and to patient neuro-imaging features. To analyze the changes of MMP2 and MMP9 plasma levels during peri-operative period and after radio-chemotherapy. Methods: Plasmatic levels of MMP2, MMP9, vascular endothelial growth factor-A (VEGFA), vascular endothelial growth factor-R2 (VEGFR2), stromal cell-derived factor 1 (SDF1) and chemokine receptor-4 (CXCR4) will be analyzed by enzyme-linked immunosorbent assay (ELISA) in pre-, post-operative period, before radiotherapy, before adjuvant temozolomide and at relapse in newly diagnosed glioblastoma. RNA expression of these factors will be analyzed by reverse transcription-Polymerase chain reaction (RT-qPCR) on frozen tumor samples, whereas protein expression will be analyzed by ELISA and immunohistochemistry. Enzymatic activity of MMP2 and MMP9 will be analyzed by zymography. Tumor volume, infiltration and perfusion degrees will be analyzed on Magnetic Resonance Imaging (MRI) performed before and after surgery and before adjuvant temozolomide. Neuro-imaging characteristics will be correlated to plasma and tissue expressions of these factors. The expected results are to better define the expression profile of MMP2, MMP9 and the change in their plasma level during treatment, a prerequisite for their clinical use.
Background Currently, no standard treatment exists for patients with recurrent glioblastoma multiforme (rGBM) and used 2nd line treatments have low (up to max. 20%) response rates and very modest response duration (months). The median overall survival for GBM patients is 12-14 months from the time of diagnosis; therefore the development of new therapeutic options is imperative. HU has been used to treat hematological diseases and solid tumors (such as melanoma, ovarian, squamous cell carcinoma, head and neck carcinoma and brain tumors) in combination with other anti-cancer agents, but never with TMZ. If found safe, HU+TMZ, is easily translated to the clinic. Purpose: Phase I trial to identify the maximum tolerated dose (MTD) for the combination of dose intense temozolomide (TMZ) and hydroxy-urea (HU) in (maximal) thirty patients with recurrent glioblastoma (rGBM). Plan of investigation: Month 0-24 (1st and 2nd year): Inclusion and follow-up of a maximum of 30 patients with rGBM Month 25-31 (3rd year): Follow-up of patients included in the trial, data analysis (determining MTD and explorative analysis) and manuscript preparation. Possible results: 1. Obtaining MTD and safety profile of daily HU+TMZ in patients with rGBM; 2. Preliminary data on the estimation of the median progression-free (PFS) and overall survival (OS), radiographic response proportion in patients with measurable disease, and exploratory correlation of treatment outcomes (PFS and OS) with o6-methylguanine-DNA-methyltransferase (MGMT) promoter methylation status in archival tumor specimens and further elucidation of underlying mechanism of re-sensitization of TMZ by HU. Exploratory analysis of biomarkers profile of platelets in patients treated with HU+TMZ.
International registry for cancer patients evaluating the feasibility and clinical utility of an Artificial Intelligence-based precision oncology clinical trial matching tool, powered by a virtual tumor boards (VTB) program, and its clinical impact on pts with advanced cancer to facilitate clinical trial enrollment (CTE), as well as the financial impact, and potential outcomes of the intervention.
This study will test an investigational drug called AZD1390 in combination with radiation therapy for the treatment of brain tumors. This is the first time AZD1390 is being given to patients. This study will test safety, tolerability and PK (how the drug is absorbed, distributed and eliminated) of ascending doses of AZD1390 in combination with distinct regimens of radiation therapy
Glioblastoma is the most common adult brain tumour with approximately 2000 new cases each year in the UK. Optimal treatment consists of surgery followed by radiotherapy and chemotherapy but despite this survival is poor with only 10% of patients alive at 5 years. Standard imaging (MRI and CT) may not detect the full extent of tumours before treatment and it can be difficult to assess how the tumour is responding to treatment. The study aims to evaluate more advanced imaging techniques to see if they are better at mapping the whole tumour and assessing response to treatment. Two different imaging techniques will be assessed: Positron Emission Tomography - Computed Tomography (PET-CT) uses a mildly radioactive compound injected into the patient which is taken up into brain tumour cells and shows up as a bright spot on scans. Brain tumours affect blood supply and how much fluid is in the brain tissue as well as how freely fluid can move around. Advanced MR imaging known as multiparametric MRI will be used to look at these additional features. This extra information may help improve planning of radiotherapy and assessing how tumours respond to treatment. Twelve adult patients with glioblastoma undergoing radical treatment will be recruited over a 12 month period. Each patient will have standard MR imaging before radiotherapy (after surgery) and 4-6 weeks following completion of radiotherapy. They will also have advanced MRI and PET/CT before, during and after treatment. The aim will be to study if this is feasible and could potentially improve radiotherapy planning and response assessment. Imaging will be interpreted by both imaging and brain tumour treatment experts.
The primary objective of the study is to determine whether overall survival of newly diagnosed glioblastoma patients treated with lysate-loaded, mature dendritic cell vaccines as add-on to the standard of care consisting of resection, radiotherapy with concomitant temozolomide chemotherapy and subsequent adjuvant temozolomide chemotherapy is superior to the treatment with the standard of care alone.
