Filter by:This phase II trial tests how well retifanlimab with bevacizumab and hypofractionated radiotherapy, compared to bevacizumab and hypofractionated radiotherapy alone, works in treating patients with glioblastoma that has come back after a period of improvement (recurrent). A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as retifanlimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Giving retifanlimab with bevacizumab and hypofractionated radiotherapy may work better in treating patients with recurrent glioblastoma than bevacizumab and hypofractionated radiotherapy alone.
PreOperative PreRAdIotherapy Tumour Treating Fields (PORTRAIT) is a Phase I study that will test the safety and feasibility of Optune administered preoperatively and preradiotherapy in patients with a new radiological diagnosis of glioblastoma (GBM). Participants will be required to undergo additional MRI sequencing scans and provide blood, tear fluid and tissue samples over a maximum of 6 months. After the study patients will follow their standard treatment pathway.
In Australia, glioblastoma (GBM) has a higher annual fatality rate than a variety of other cancers, such as melanoma, bladder, and kidney tumors. While the 5-year survival rate for other cancers, such as breast and prostate cancer, has increased, there have been no notable advancements in GBM during the past ten years, and the incidence and mortality patterns have barely changed between 1982 and 2011. In particular, GBM poses a challenging therapeutic dilemma for patients and physicians due to its aggressive biology and resistance to available treatments. Recent studies showed that cytomegalovirus (CMV) is expressed in GBM tumors, making it a good target for immunotherapy trials. This phase I trial aims to determine the safety and tolerability of the PEP-CMV vaccine in patients with newly diagnosed MGMT-unmethylated GBM in combination with one cycle of adjuvant temozolomide.
The goal of this interventional study is the development and validation of imaging markers, MRI and PET, plasma biomarkers, and/or cell markers that could support clinicians and researchers in differentiating pseudoprogression from true tumor progression in routine clinical activities and clinical trials in patients affected by glioblastoma. The endpoints of the study are: - the elaboration of predictive models using imaging advanced biomarkers, PET and MRI, biological serum markers, and cancer cell derived makers to differentiate tumor pseudoprogression or real progression in patients affected by glioblastoma who underwent therapeutical protocol as per treating physicians' indications (Stupp or hypofractionated RT) - to establish an in vivo murine model of pseudoprogression by orthotopic transplantation of glioblastoma stem cells derived from thirty-five patient subjected to subsequent treatment with irradiation and temozolomide administration. Participants will undergo: - baseline MRI and 18F-GE-180 PET imaging, and blood withdrawal - surgery - collection of glioblastoma stem cells (and hematopoietic stem cells from a sub-group of subjects) - standard treatment with radiotherapy and chemotherapy - MRI every 3 months - PET and blood withdrawal in case of MRI evidence of either suspected tumor progression or pseudoprogression - second surgery OR stereotactic biopsy OR clinico-radiological follow-up as for standard of care according to the Institutional Multidisciplinary Brain Tumor Board
This is a Phase 1/2a, open-label study to evaluate the safety, tolerability, immunogenicity, and preliminary clinical activity of RZ-001 administered in combination with VGCV in subjects with hTERT-positive GBM.
The goal of this phase I interventional study is to determine the safety and feasibility of the proposed investigational (neo-)adjuvant treatment regimen in patients with resectable reccurent glioblastoma. Participants will: - receive neo-adjuvant administration of intravenous immunotherapy - followed by a maximal safe neurosurgical resection - afterwards, immunotherapy will be injected into the brain tissue - followed by insertion of an Ommaya reservoir - postoperatively, administration of immunotherapy will be continued
This is a phase 2 open-label study to evaluate the safety and efficacy of N-803 and PD-L1 t-haNK when combined with Bevacizumab in subjects with recurrent or progressive GBM. Participants will receive N-803 subcutaneously (SC), PD-L1 t-haNK intravenously (IV), and Bevacizumab IV combination therapy. Treatment for all enrolled participants will consist of repeated cycles of 28 days for a maximum treatment period of 76 weeks (19 cycles). Treatment will be administered on days 1 and day 15 of each cycle. Treatment will be discontinued if the participant reports unacceptable toxicity (not corrected with dose reduction), withdraws consent, if the Investigator feels it is no longer in the participant's best interest to continue treatment, or the participant has confirmed progressive disease by iRANO, unless the participant is potentially deriving benefit per Investigator's assessment. Participants will be followed for collection of survival status every 12 weeks (± 2 weeks) for the first 2 years, then yearly thereafter.
The aim is to improve patients' compliance to TTFields therapy by a psychological video intervention in a multi-center, randomized controlled trial.
Glioblastoma is the most common primary malignancy of the central nervous system with a very poor prognosis. Most of the immunotherapies that have made significant breakthroughs in the treatment of other tumors in recent years are unsatisfactory in the application of glioblastoma, which is mainly inseparable from the highly inhibitory immune microenvironment formed by the latter. Therefore, how to change this "immune desert" and better activate immune effector cells to play an anti-tumor effect is currently a hot spot in glioma immune research. In recent years, there has been continuous research support that the myeloid cells of the central nervous system are partly derived from the bone marrow of the skull, and there is a special channel connection between the skull and the dura mater, through which immune cells can be transported. This suggests that some of the tumor-associated macrophages recruited in the glioblastoma microenvironment may be passed through the dura mater. In previous animal experiments, we blocked the main blood supply to the dura mater by ligating the bilateral external carotid arteries of mice, cutting off the potential supply of dura mater to suppressor myeloid cells in the lesion. The results showed that after ligation of bilateral external carotid arteries, the survival period of tumor-forming mice was significantly prolonged and the prognosis was improved. The proportion of myeloid cells in the tumor microenvironment of mice decreased significantly, and the expression of tumor suppressor molecules such as arginase Arg1 decreased, indicating that the improvement of mouse prognosis was closely related to the proportion and phenotypic changes of myeloid cells after dural blood supply blockade. The meningeal lymphatic system of the human central nervous system has been shown to be an important part of the immune system, while the external carotid artery system, the main source of blood supply to the dura, carries abundant immune cells that ooze out to the dura mater through the endothelial window hole of the dural blood vessel, which is an important source of dural immune cells. In the glioblastoma immune microenvironment, the source of immune cells includes dural branches from the external carotid artery system in addition to branches of the internal carotid artery system. Therefore, for patients diagnosed with glioblastoma, this study involves embolization of the dural branch of the external carotid artery system (bilateral middle meningeal artery) to block the dural blood supply before craniotomy. At the same time, microsurgery under multimodal image navigation was used to remove the tumor. It is expected to be effective in reducing the proportion of myeloid suppressor cells in the tumor microenvironment, slowing the growth rate of residual tumor cells, and prolonging the tumor-free progression and survival of patients.
This will be a prospective, open label, single center, phase I lead-in study of 10 patients to a single arm phase-II study of 37 additional patients to assess the effectiveness of pembrolizumab and lenvatinib combination therapy for recurrent glioblastoma (rGBM) patients wearing TTFields electrodes.
