NCT06622434
This phase I/II trial evaluates the safety and the immunological efficacy of a cancer vaccine against 2 glioma-associated antigens in newly-diagnosed glioblastomas. The objectives of this study are as follows: Primary objective * phase 1: * to assess the maximum tolerated dose (MTD) and select the recommend Phase 2a dose * phase 2a: * to assess anti- TERT specific T cell responses at 2 months at the selected dose level Secondary objectives: * To assess Short and long-time immunological safety * To assess Evolution of anti-PTPRZ1 and anti-TERT immune T cell responses over time * To assess Progression free survival (RANO 2.0 criteria) * To assess Overall survival * To assess Quality of life by EORTC QLQ30 and BN20 questionnaires as well as objective of ancillary study: to determine the mechanism of action of potential tumour escape in GBM (T-cell lymphocyte phenotype; antigen expression and checkpoint inhibitors on tumour cells at relapse, if available), analysis of circulating antibodies against TERT epitope and/or melanin, and identification of predictive biomarkers of response. Ultimately, this trial together will lead to the implementation of future phase III trial in GBM. All patients enrolled in the study will receive standard treatment consisting of surgical resection of the tumor followed by radio-chemotherapy. Immunotherapy will begin 4 weeks after the completion of radiotherapy.
NCT04474353
The purpose of this study is to determine the safety and efficacy of the combination therapy of TTFields + SRS+ Temozolomide (TMZ) for newly diagnosed glioblastoma (GBM).
NCT05864534
Brain tumor treatment is hampered by the blood-brain barrier (BBB). This barrier prevents drugs carried in the bloodstream from getting into the brain. If the BBB can be opened, making it temporarily more permeable, drugs may able to better reach the brain tumor. In this trial we will implant a novel device with 9 ultrasound emitters, allowing temporary and reversible opening of the BBB to maximize brain penetration of drugs that modulate the immune system. The device will be implanted after radiation is completed. Immune modulating drugs will be given every 3 weeks in conjunction with activation of the device to open the BBB. The objectives of this trial are to establish whether it is safe and feasible to administer immune modulating drugs in this manner, and identify whether the treatment is effective in treating glioblastoma.
NCT03345095
The standard of care for newly diagnosed glioblastoma includes surgery, involved-field radiotherapy, and concomitant and six cycles of maintenance temozolomide chemotherapy, however the prognosis remains dismal. Marizomib has been tested in patients with newly diagnosed and recurrent glioblastoma in phase I and phase II studies. In patients with recurrent glioblastoma, marizomib was administered as a single agent or in combination with bevacizumab (NCT02330562). Based on encouraging observations, a phase I/II trial of marizomib in combination with Temozolomide+Radiotherapy(TMZ/RT) followed by Temozolomide (TMZ) in newly diagnosed glioblastoma has been launched (NCT02903069) which explores safety and tolerability of this triple combination and which shall help to determine the dose for further clinical trials in glioblastoma. In this context, given that marizomib has been established as a safe addition to the standard TMZ/RT --\>TMZ, a phase III study is considered essential to establishing its impact on overall survival.
NCT03400917
This is a single-arm, open-label phase II clinical trial in which approximately 55 patients with newly diagnosed glioblastoma (GBM) will be enrolled with the intent to receive an autologous dendritic cell vaccine consisting of autologous dendritic cells loaded with autologous tumor-associated antigens (AV-GBM-1).
NCT03619239
Patients will be enrolled in two stages: * Dose-escalation stage: Approximately 12-24 patients will be enrolled.
NCT04488783
Glioblastoma (GB) is the most common and aggressive type of primary malignant brain tumor in adults. Despite advances in surgical resection, radiotherapy and chemotherapy, prognosis remains very poor. Temozolomide (TMZ) as an alkylating agent has become part of GBM management but it has contributed only marginally to prolongation of life in GBM patients. Our aim is to evaluate the therapeutic potential of the trace element zinc to facilitate temozolomide tumor cell toxicity in GBM. P53 gene is inactive/mutant in most of these patients which may affect the resistance to apoptosis of tumor cells by chemotherapy. Zinc (Zn) has a crucial role in the biology of p53, in that p53 binds to DNA through a structurally complex domain stabilized by zinc atom. We have shown that the cytotoxic activity of TMZ is substantially increased with the addition of zinc in vitro with GBM cell lines as well as in vivo, with intracranial GBM xenografts. Numerous studies of zinc in animal models and in human subjects support its use in the treatment and possibly the prevention of cancer. Zinc has been consumed by the public as an essential mineral (and thus is category A drug) in concentrations which allows this effect with Temozolomide. Vitamin C could add to this by priming the immune system for lymphocyte- linked cancer killing. The vitamin c increases the number of tumor infiltrating lymphocytes and enhances the activation of the immune system.We propose a single arm phase II clinical trial in 30 newly diagnosed GBM patients who will be treated with the standard chemo-radiotherapy with the addition of zinc and vitamin C.
