Predictive Value of Soluble CD146 in Glioblastoma Patients
Glioblastoma is the most common malignant primary brain tumor with poor prognosis because of its diffusive and infiltrative nature. The FDA approved the use of the anti-VEGF antibody bevacizumab in recurrent GBM. However, resistance to this anti-angiogenic reagent is frequent and fails to enhance patients' overall survival. The investigators previously identified one novel mechanism responsible for bevacizumab-resistance in CD146-positive glioblastoma (Joshkon et al. Acta Neuropathol Commun, 2022). Now, the investigators objective is to prospectively monitor the soluble CD146 value in plasma from patients treated by bevacizumab for...

PreOperative Brain Irradiation in Glioblastoma
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)).

Profiling Program of Cancer Patients With Sequential Tumor and Liquid Biopsies (PLANET)
The proposal is to conduct a prospective, multi-cohort study aiming to decipher molecular profiles/biological characteristics of advanced cancer patients during the course of their disease with longitudinal and sequential analyses of tumor and liquid biopsies. This approach will allow i) to develop a model in order to predict tumor response / resistance in real life conditions and to better understand adaptive mechanisms and ii) to potentially propose therapeutic options to enrolled patients following the review of the biological/molecular data generated during this study and during a Molecular Tumor Board in case of disease ...

Prospective Cohort of Patients With Newly Diagnosed Glioblastoma: Analysis of MMP2 and MMP9 Expression and Correlation to Neuro-imaging Features.
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...

Prospective Evaluation of AI R&D Tool in Adult Glioma and Other Primary Brain Tumours (PEAR-GLIO)
Pear Bio has developed a 3D microtumor assay and computer vision pipeline through which the response of an individual patient's tumor to different anti-cancer regimens can be tested simultaneously ex vivo. This study will recruit patients with primary brain tumors who are due to undergo surgery. Oncologists will be blinded to treatment response on the Pear Bio tool (the assay will be run in parallel with the patient's treatment). The primary objective of this study is to establish the ex vivo model and confirm whether approved therapies exhibit their intended mechanism of action in the model. Secondary objectives include...

Protective VEGF Inhibition for Isotoxic Dose Escalation in Glioblastoma
Glioblastoma is the most aggressive brain tumor and often recurs locally despite intensive treatment. Standard chemoradiotherapy with 60 Gy may not be sufficient to control the tumor, and dose escalation seems to be warranted, but causes more toxicity. To address this, the multicentric PRIDE trial employs two cycles of bevacizumab to achieve dose escalation isotoxically. The goal is improved survival without significantly increasing side effects. The study uses a simultaneous integrated boost with a total dose of 75 Gy in 2.5 Gy per fraction.

Radiation/Temozolomide and Immunotherapy With Daratumumab to Improve Antitumor Efficacy in Glioblastoma
TMZ is a standard therapy for GBM. The study will demonstrate that Daratumumab can collaborate with TMZ to enhance the cytotoxicity against GBM cells. Collectively, the preclinical data along with existing in vivo studies by others provides the rationale for therapeutic targeting of CD38 in GBM and its microenvironment. Daratumumab is commercially available, is safe and well tolerated when combined with alkylating chemotherapy, radiation therapy and has attained therapeutic CSF levels. Thus, the addition of Daratumumab to the frontline treatment regimen of GBM can potentially have a significant clinical benefit. Approximately 16...

Radiodynamic Therapy (RDT) With Gliolan in Patients With First Recurrence of Brain Tumor
The investigational drug 5-ALA (known under the trade name Gliolan®) is an approved drug for the surgical removal of malignant glioma (WHO grade III and IV). In this trial, the drug is being tested outside of its actual approval as a radiosensitizer in combination with conventional radiotherapy for first-time recurrence (relapse) of malignant glioma. In this clinical trial, the investigational drug 5-ALA is being used for the first time in a multiple dose escalation regimen in combination with radiotherapy following surgical removal of a recurrent malignant glioma in humans. The investigational drug, 5-ALA, has been used as a single...

Radioimmunotherapy With Lu-177 Labeled 6A10 Fab-fragments in Patients With Glioblastoma After Standard Treatment
Locoregional, intracavitary radioimmunotherapy (iRIT) with a newly developed radioimmunoconjugate (Lu-177 labeled 6A10-Fab-fragments) will be used to prevent or postpone tumour recurrence in patients with GBM following standard therapy . Following study objectives will be analyzed: - Determining the Maximum Tolerated Dose (MTD) - Determining safety by assessing all new neurological, hematological and other AEs CTC grade 2 or higher - Determining absorbed dose to the 2 cm shell of the resection cavity (based on a series of SPECT/CTs of the head 2h,24h,48h, 72h p.i. and on day 5-7) - ...

Radiotherapy Planning Using Fluciclovine PET in Patients With Newly Diagnosed Glioblastoma
The purpose of the this study is to see if the use of a PET scan with 18F-fluciclovine (PET or Fluciclovine PET) in addition to the normal radiation planning imaging procedures (MRI and CT scan) will help determine the areas where the radiation therapy is to be delivered. It is also a goal of the study to determine if subjects live longer when treatment plans for radiation therapy are designed using a Fluciclovine PET scan, as well as MRI and CT scans. We will also collect information on if and where the tumor returns. Information on the side effects from the two different treatment planning imaging methods will also be collected. ...
