Active clinical trials for "Glioblastoma"

Pseudoprogression is a phenomenon related to post-treatment rearrangements (including radiation necrosis). It appears early in the first year after treatment and accounts for 30 to 50% of patients followed with glioblastoma. On MRI (current gold standard with international therapeutic response evaluation criteria RANO 2010), pseudoprogression is manifested by a progression of morphological abnormalities (contrast enhancement, FLAIR hypersignal) and can simulate tumor recurrence, even though the corticosteroid improved or kept clinical symptoms stabilized. In view of prognosis, the current diagnostic tools have not enough diagnosis accuracy for differentiation between pseudo-progression and early tumor recurrence, and are based on MRI retrospective analysis (2-3 months after). Recurrence of glioblastoma, is characterized by a higher amino acid metabolism than pseudoprogression, also 11C-Methionine (11C-MET), positron emitting radiotracer, showed promising results to differentiate these two entities. To date, hybrid 11C-MET PET-MRI studies remains limited to small sample size (a few dozen patients), and none focuses exclusively on glioblastoma. Hypothesis of our study is that 11C-MET PET-MRI may be performed as a first-line MRI for suspected pseudoprogression and may changes therapeutic decision making and also patient prognosis. The main objective is to evaluate the performance of hybrid PET-MRI imaging with 11C-MET to differentiate pseudoprogression from glioblastoma recurrence in patients treated with surgery and radiochemotherapy, compared to multimodality MRI).

Autoimmune encephalitis (AE) and paraneoplastic neurological syndromes (PNS) are rare disease that could be difficult to diagnose. So it necessary to obtain numerous sample from different disease to develop more specific diagnosis kit It could be possible through the characterisation of new genetic biomarkers.

This pilot study investigates whether advanced diffusion-weighted MRI (ADW-MRI) can differentiate between true tumor progression (TP) and a pseudoprogression (PsP) in patients with glioblastoma (GBM) or brain metastases.

Glioblastoma (GBM) is the most frequent primary brain tumor and the brain tumor with the poorest prognosis. The current treatment relies on surgical resection of gross tumor followed by radiochemotherapy and adjuvant therapy with temozolomide. After such therapy, most patients experiment recurrence and few therapeutic option are available. Despite such therapies, median survival only reaches around fifteen months. There is a strong rational to develop telomerase vaccine in GBM. Telomerase (TERT) is a major oncogene, particularly in primary brain tumors 24. Alterations in TERT are very frequent in central nervous system tumors, seen most commonly in gliomas25. Mutations in the TERT promoter are found in approximately 80% of primary glioblastoma (GBM). These findings strongly support the rational to develop vaccine targeting telomerase in GBM. The aim of this project is to evaluate UCPVax treatment in glioblastoma. UCPVax is a therapeutic anti-cancer vaccine based on the telomerase-derived helper peptides designed to induce strong TH1 CD4 T cell responses in cancer patients (NCT02818426).

This phase II trial studies how well F-18 fluoroethyltyrosine (fluoroethyltyrosine) works in detecting tumors in participants with intracranial tumors that have come back. Imaging agents, such as fluoroethyltyrosine, may help doctors see the tumor better during a positron emission tomography (PET) scan.

Glioblastoma multiforme (GBM) is the most common primary brain tumor in adults. The treatment comprises maximal safe resection followed by radiotherapy and chemotherapy. Despite appropriate management, 90% of the patients will develop relapse or progression. After progression, the median survival is 5.2 months (Stupp, 2009). The treatment of GBM relapse remains investigational. Reirradiation is an option in selected cases. The objective of this study is to compare 2 schemes of stereotactic hypofractionated radiotherapy in the management of recurrent GBM.

This pilot clinical trial studies fluordeoxyglucose (fludeoxyglucose) F-18 (FDG) positron emission tomography (PET)/computed tomography (CT) in monitoring very early therapy response in patients with glioblastoma. Diagnostic procedures, such as FDG PET/CT, may help measure a patient's response to earlier treatment. Chemotherapy can induce very rapid changes to the tumor's glucose consumption which can be measured with imaging. FDG PET/CT shortly after the start of therapy may help identify very early therapy response in patients with glioblastoma.

ONC201 is a new drug candidate that kills cancer cells but not normal cells in laboratory studies and has been previously evaluated in a phase I clinical trial in advanced cancer patients. This clinical trial will enroll patients with recurrent glioblastoma or recurrent WHO Grade IV gliomas with the H3 K27M mutation.

Single center, non-randomized, Phase 0 study. Sacituzumab Govitecan given preoperatively, followed by craniotomy with surgery or biopsy of brain tumors (GBM and metastatic brain tumors from Breast) and intraoperative tissue collection will follow with contemporaneous CSF (depending on tumor location) and whole blood (serum) sampling.

Glioblastoma patients are confronted with a debilitating disease associated with a low survival rate and poor quality of life. The goal of this study will be to reach a largely underrepresented population in the exercise literature and explore the role of a tailored circuit-based resistance training program on functional fitness (i.e., ability to carry out tasks of daily living) and associated health outcomes (e.g., quality of life) for GBM patients on active treatment.
