99mTc-CNDG SPECT/CT in Brain Tumors
The goal of this clinical trial is to evaluate the value of 99mTc-CNDG for diagnosis of brain tumors by comparing it with 18F-FDG-PET. The main questions it aims to answer are: 1. What is the diagnostic consistency between 99mTc-CNDG and 18F-FDG? 2. What is the correlation between the SUVmax value of 99mTc-CNDG and tumor type? Participants will: Receive18F-FDG-PET and 99mTc-CNDG examination within 2 weeks before surgery. Obtain pathological diagnosis by surgery or biopsy as the gold standard.

Abemaciclib in Newly Diagnosed Meningioma Patients
This study is being done to learn about how an investigational drug called abemaciclib works in treating patients with a newly-diagnosed grade 3 meningioma. Abemaciclib is a drug that is approved by the FDA, but not for brain tumors. Participants who consent to the trial will have surgical tissue collected from the planned surgical resection and tested. If the tissue shows positive results for RB cells and participants are qualified, they will be enrolled and receive study treatment two to five weeks after completing standard-of-care radiation therapy. This is a randomized clinical trial which means that participants will be...

A Biomarker-Guided Phase 2 Study of DB107-Retroviral Replicating Vector (RRV) Combined With DB107-Flucytosine (FC) Extended-Release Tablets
The purpose of this study is to determine if the investigational products, DB107-RRV and DB107-FC, as a combination treatment will shrink high-grade glioma (HGG) in patients with recurrent/progressive, resectable or unresectable disease and increase the time that disease is controlled.

Accuracy of Robotically Assisted Cranial Biopsies
This is an observational post-market study determining biopsy accuracy in a clinical environment using Cirq® Robotic Alignment Module Cranial. The goal is to determine whether the robotic procedure to be examined can achieve a clinically acceptable value of at least 90% in terms of diagnostic yield.

A Clinical Study of Intratumoral MVR-C5252 (C5252) in Patients With Recurrent or Progressive Glioblastoma
This is a Phase 1 open label, first in human study of C5252 monotherapy designed to determine the safety and tolerability of a single intratumoral (IT) injection of C5252 in patients with recurrent or progressive glioblastoma (GBM).

A Clinical Trial on Combined (Neo-)Adjuvant Intravenous Plus Intracranial Administration of Ipilimumab and Nivolumab in Recurrent Glioblastoma
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

A Close Examination of Patient Experiences in Glioblastoma Multiforme Clinical Research
Clinical research can sometimes favor certain demographic groups. Additionally, there is limited research that delves into the factors that influence participation in clinical study, both positive and negative. The goal is to identify the obstacles and challenges that prevent participation in glioblastoma multiforme clinical study, as well as the reasons for withdrawal or discontinuation. Insights gained from this study will ultimately benefit those with glioblastoma multiforme who may be invited to participate in clinical trial in the years to come.

Activated Autologous T Cells Against Glioma Cancer Stem Cell Antigens for Patients With Recurrent Glioblastoma
The purpose of this study is to examine the use of activated T cells (ATCs) to assess the safety and tolerability of autologous activated T cells, as measured by the number of Grade 3 or higher toxicities, the number of serious adverse events, and treatment-related toxicities, according to National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI CTCAE) Version 5, to find the maximum tolerated dose. The secondary objectives include evaluating the rate of overall survival, rate of progression-free survival, health-related quality of life parameters, overall response rate, immune response, and tumor stem cell antigen...
