Filter by:This phase II trial studies whether different imaging techniques can provide additional and more accurate information than the usual approach for assessing the activity of tumors in patients with newly diagnosed glioblastoma. The usual approach for this currently is magnetic resonance imaging (MRI). This study is trying to learn more about the meaning of changes in MRI scans after treatment, as while the appearance of some of these changes may reflect progressing tumor, some may be due the treatment. Dynamic susceptibility contrast (DSC)-MRIs, along with positron emission tomography (PET) and/or magnetic resonance (MR) spectroscopy, may help doctors tell which changes are a reflection of the treatment and which changes may be due to progressing tumor.
The study evaluates safety, tolerability, pharmacokinetics at recommended phase II dose (RP2D) and preliminary antitumor activity of Niraparib + dd-TMZ "one week on, one week off" in patients affected by recurrent GBM IDH wild-type and recurrent IDH mutant (WHO grade 2-4) gliomas. The treatment will be administered until progressive disease, unacceptable toxicity, consent withdrawal, lost to follow-up or death. The entire study is expected to last approximately 40 months.
As a part of molecular imaging, many PET tracers have been investigated in this regard. Those include 18F-FDG being glucose analogue, 18F-FLT representing nucleoside metabolism, and 18F-FDOPA, 18F-FET, 11C-MET as amino acids analogues. Among these, 18F-FDG is the most commonly used tracer due to its broader use and easy availability. However, high physiological uptake in the brain is a significant limitation. The main limitation of other tracers is the need for onsite cyclotrons for their production, making their availability difficult. So, the search for an ideal modality is still ongoing, and the latest addition to this search is a radio ligand labeled Prostate Specific Membrane Antigen (PSMA). It is a new but potentially promising radiotracer, currently showing its utility in different malignancies. Investigators, therefore, aim to identify whether Ga-68 PSMA PET-CT has better diagnostic accuracy in the detection of recurrent gliomas than conventional imaging modalities.
This trial is a translational, open-label, monocentric prospective study of 80 patients aiming to study resistance mechanisms as well as biomarkers of resistance or sensitivity to TTFields. The study will be conducted on a population of patients with newly diagnosed glioblastoma treated with radio-chemotherapy followed by TTFields in the context of either routine care or a clinical trial. In this study, the Optune® system (battery operated device which delivers TTFields to the brain) will not be under investigation. For each included patient, blood samples will be collected during baseline visit (before initiation of radio-chemotherapy), then before initiation of TTFields and every 3 months during TTFields treatment. Additional blood samples will be scheduled at recurrence (if applicable). Moreover, tumor samples (formalin paraffin embedded (FFPE) tumor block and fresh samples) will be collected from surgery specimen on primary tumor by the sponsor for analysis. In case of recurrence, and if a second surgery is possible, tumor samples will also be collected. Tumor samples will be collected from biopsies taken in the course of routine practice and from surgical specimens collected during surgical procedure. No additional biopsies will be performed for the study. Patients will be followed-up for time to progression and overall survival for a maximum duration of 24 months from the TTFields initiation. MRI performed by patients during the course of the study will be collected by the sponsor for additional future research purposes.
The study of investigators indicated that TMZ can up-regulate dopamine D2 receptor (DRD2) expression, and mediates Ferroptosis inhibition and chemoresistance of GBM. The clinical data also proved that the DRD2 expression in recurrent GBM is significantly higher than that in primary GBM. Moreover, the DRD2 antagonist haloperidol can attenuate the above function of DRD2, and increase the sensitivity of GBM to the TMZ by inducing fatal autophagy and ferroptosis. In xenograft mice, the combined usage of haloperidol and Temozolomide (TMZ) can significantly inhibit tumor growth and increase overall survival. The investigators' findings have been published in Clinical cancer research. Haloperidol known as a butylbenzene antipsychotic drug, has been widely used in several kinds of mental illnesses, such as depression, schizophrenia, and Bipolar disorder. And the safe dosage of the haloperidol is clear so far. So in this study, the investigators will recruit the patients who suffered from recurrent GBM, and evaluate the effectiveness of single TMZ chemotherapy or combined with haloperidol.
The purpose of this study is to determine how safe and how well-tolerated the experimental study drug, C134 is when re-administered into the brain where the tumor is located.
Temozolomide provided significant and clinically meaningful benefit in MGMT gene promoter methylation glioblastoma. However, in unmethylated patients, the effect of Temozolomide is limited. The aim of this study is to compare the effect of Cisplatin plus Temozolomide and Temozolomide in patients with MGMT gene promoter unmethylation glioblastoma
The purpose of this research study is to determine the safety and efficacy of administering two doses of lerapolturev in residual disease (within tumor margins) after surgery, followed later by repeated injections of lerapolturev in the subcutaneous area (under the skin) around the lymph nodes of the head and neck for adult patients diagnosed with recurrent glioblastoma at the Preston Robert Tisch Brain Tumor Center (PRTBTC) at Duke.
Standard of care therapy and all FDA approved adjuvant therapy for glioblastoma continue to provide < 12-month progression free survival (PFS) and < 24-month overall survival (OS). Standard of care therapy continues to be defined by the volume of tumor that enhances with gadolinium on standard magnetic resonance imaging (MRI). The investigators have identified a significant tumor burden in non-enhancing (NE) regions beyond the contrast-enhancing (CE) portion of tumor. Furthermore, the investigators have adapted a pH-sensitive technique called amine chemical exchange saturation transfer (CEST) MRI to identify tumor cells in NE regions with high sensitivity and specificity. This study is a randomized trial of CEST based resections versus standard of care in newly diagnosed glioblastoma with primary endpoint of progression free survival and secondary endpoints of overall survival and quality of life metrics. The hypothesis being tested is whether surgical resection of infiltrating tumor cells visualized by CEST MRI contributes to survival in glioblastoma patients.
The goal of this study is to determine the efficacy of the study drug olutasidenib to treat newly diagnosed pediatric and young adult patients with a high-grade glioma (HGG) harboring an IDH1 mutation. The main question the study aims to answer is whether the combination of olutasidenib and temozolomide (TMZ) can prolong the life of patients diagnosed with an IDH-mutant HGG.
