Filter by:This is a pilot imaging study in participants treated with stereotactic radiosurgery (SRS) to treat brain metastasis. The purpose of this study is to see whether 18F-Fluciclovine positron emission tomography (PET) can be used as a biomarker to measure response or progression of brain metastasis after SRS.
Background: Primary or secondary brain tumors (metastases) remain associated with a very poor prognosis linked to significant therapeutic resistance. Thus, glioblastoma, which is the most common and aggressive primary brain tumor in adults, is associated with inevitable relapses within 7 to 10 months and median survival of approximately 12 to 14 months. At the same time, brain metastases are increasingly increasing following better systemic control of other metastatic sites and improvement in detection methods. However, they remain resistant to the latest therapeutic innovations such as immunotherapies or targeted therapies. In this context, innovative strategies are necessary to identify new therapeutic targets and implement new treatments to overcome resistance phenomena in the clinic. Objective: Our goal will be to generate tumoroids and stem-like cell lines (PDX) from patient tumor samples. Methods: We will establish tumor tumoroids and stem cell lines from patient samples. These preclinical models will allow us to test a large number of drugs, quickly and efficiently thanks to models as close as possible to patient tumors and limiting the use of animal models (3R). Overall, this project should enable major advances in the treatment of glioblastoma and brain metastases and enable the rapid testing of new molecules in clinical trials thanks to the homology of our models with our patients' diseases.
Despite the impressive response rate to third-generation EGFR-TKIs, resistance inevitably develops in most patients. Stereotactic radiotherapy plays a growing role in the management of patients with brain metastasis. This study aims to evaluate the efficacy and safety of stereotactic radiotherapy for oligo-residual intracranial disease after first-line third-generation EGFR Inhibitors.
This study will apply novel MRI approaches with established sensitivity to tissue oxygen consumption and perfusion to predict hypoxia-associated radiation resistance, manifested as tumor recurrence and progression post-treatment.
This study will consist of a Phase 1b and Phase 2 portion. The Phase 1b portion will enroll first followed by the Phase 2 portion. Each cycle of treatment = 28 days. Subjects will receive alectinib twice daily. Those in the Phase 1b portion will receive alectinib alone. Those in Phase 2 Arm A will receive alectinib alone. Those in Phase 2, Arm B will receive SRS + alectinib. A maximum of 25 cycles (2 years) of alectinib may be administered on study.
The aim of the study is to determine whether the use of the CEST sequence would have diagnostic performance equivalent to the reference method of T2* infusion with contrast injection in the diagnosis of radionecrosis of lung cancer brain metastases.
This study is to evaluate the efficacy and safety of TY-9591 in first-line treatment of patients with EGFR-sensitive mutation-positive non-small cell lung cancer with brain metastases compared to Osimertinib.
Patients suffering from malignancies in advanced stages often develop brain metastases, which limit both the life span and the quality of life. Combining surgery and radiotherapy for resectable brain metastases is standard of care but there is a lot of controversy on which kind of radiotherapy is best suitable. Recently, first volumetric in-silico analyses point to theoretical advantages of neoadjuvant stereotactic radiotherapy of brain metastases. Special about this trial is the direct comparison between the three currently discussed radiotherapy options for resectable brain metastases: Neoadjuvant stereotactic radiotherapy, intraoperative radiotherapy and adjuvant stereotactic radiotherapy.
This trial uses multi-parametric magnetic resonance imaging (MRI) to develop and validate imaging risk score to predict radiation necrosis in participants with brain metastasis treated with radiation therapy. Diagnostic procedures, such as multi-parametric magnetic resonance imaging (MRI), may improve the ability to diagnose radiation necrosis early and help establish treatment strategies.
The purpose of the study is to determine in brain metastases and according to feasibility in liquid biopsies: - Molecular alterations including in particular mutations, amplifications, Copy number gene variants and fusion transcripts identified by high-throughput sequencing; - The rate of variation either in gain or in loss of expression of the different messenger Ribonucleic Acids by analysis of the transcriptome; - Epigenetic alterations by methylation of deoxyribonucleic acid clusters by methylome chips.
