Active clinical trials for "Glioblastoma"

The purpose of this study is to evaluate the safety of the Exablate Model 4000 Type 2.0 used as a tool to disrupt the BBB in patients with high grade glioma undergoing standard of care therapy.

The objectives of this registry study are to evaluate real-world clinical outcomes and patient reported outcomes that measure the effectiveness and safety of STaRT.

Glioblastoma is the most aggressive kind of brain cancer and leads on average to 20 years of life lost, more than any other cancer. MRI images of the brain are taken before the operation, and every few months after treatment, to see if the cancer regrows. It can be hard for doctors to tell if what they see in these images represent growing cancer or a sideeffect of treatment. The similarity of the appearance of the treatment side-effects to cancer is confusing and is known as "pseudoprogression" (as opposed to true cancer progression). If doctors mistake the appearance of treatment side-effects for growing cancer, they may think that the treatment is failing and change the patient's treatment too early or put them into a clinical trial. This means that patients may not be given the full treatment and the results from some clinical trials cannot be trusted. The aim of this study is to provide doctors with a computer program that will use MRI images of the brain that are routinely obtained throughout treatment, in order to help them more accurately identify when the cancer regrows.

In patients operated for glioblastoma, glioma stem-like cell lines will be obtained from tumor tissue, and IPSCs from skin fibroblasts or PBMCs. Brain organoids will be generated from IPSCs and co-cultured with IPSCs to study brain invasion and ciliogenesis. 3D genome architecture of glioma stem-like cells will be investigated. Gene modulation and pharmacologic strategies to inhibit invasion and restore ciliogenesis will be explored.

The goal of this phase 1 dose finding study is to to assess the clinical tolerability and safety of escalated dose proton therapy in glioblastoma patients treated with multimodality treatment, according to treatment volume. The main questions it aims to answer are: what is the maximum tolerated proton dose in glioblastoma patients? is the maximum tolerated proton dose in glioblastoma patients dependent on treatment volume? what is the recommended phase 2 proton dose in glioblastoma patients? Patients will be asked to undergo radiotherapy to step-wise escalated doses using proton therapy as part of their multimodality treatment. Patients will be monitored closely for treatment effects.

This is a single-center, open, dose-increasing study. For subjects with recurrent glioblastomaIt ,is estimated that about 22 subjects will be enrolled, The main purpose was to evaluate the safety and tolerance of Epidermal Growth Factor Receptor Variant III Chimeric antigen receptor T(EGFRvIII CAR-T) in the treatment of patients with recurrent glioblastoma.The secondary purpose is to preliminarily evaluate the anti-tumor activity of Epidermal Growth Factor Receptor Variant III Chimeric antigen receptor T(EGFRvIII CAR-T) in the treatment of patients with recurrent glioblastoma, and preliminarily evaluate the relationship between the clinical efficacy, safety and pharmacokinetics of Epidermal Growth Factor Receptor Variant III Chimeric antigen receptor T cells(EGFRvIII CAR-T cells) preparation, as well as their correlation with tumor markers or other potential biomarkers. This clinical study is an open clinical study, including dose increasing stage and expansion stage. The main objective of the study was to observe the efficacy and safety of Epidermal Growth Factor Receptor Variant III Chimeric antigen receptor T cells(EGFRvIII CAR-T cells) in the treatment of Glioblastoma (GBM) by local administration (Omaya capsule administration). The study will be divided into the following stages: screening stage, baseline stage, treatment stage, short-term follow-up and long-term follow-up stage.

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.

This is an ongoing Phase 2, open-label, single-center, non-randomized study of sintilimab (one anti-PD-1 antibody same as nivolumab approved in China) plus bevacizumab administered in a low dosage schedule in adult (≥ 18 years) participants with a clinical relapse or circulating tumor DNA (ctDNA)-level relapse of glioblastoma (GBM). This study has two non-comparative study groups. Both cohorts will receive the same study drug sintilimab 200mg and bevacizumab 3mg/kg every 3 weeks. A stringent two-step non-randomized process will be used to assign participants to one of the study groups. Neither participants nor doctors but the researcher can choose which group participants are in. No one knows if one study group is better or worse than the other. 60 total participants are expected to participate in this study (30 participants in each cohort). Grouping process: After enrollment, under the standard of care, participants will receive regular tumor in situ fluid (fluid within the surgical cavity, TISF) sampling for ctDNA analysis and recceive regular MRI. The researcher will study the TISF ctDNA and imaging dynamics to determine whether the tumor reaches to ctDNA-level (Cohort 1) or clinical relapse (Cohort 2). At the first step, all timely identified as ctDNA-level relapse tumors will be assigned into the Cohort 1 and receive the study drug immediately, those failed to be timely identified will be assigned into the Cohort 2 and receive the study drug after the clinical relapse. At the second step, once either group reaches the target number, the new participants will be all assigned into the other Cohort.

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.
