Recurrent Glioma

In this study, the safety, tolerability and preliminary effectiveness of GNC-039 in patients with relapsed/refractory or metastatic glioma or other solid tumors will be investigated to assess the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) or maximum administered dose (MAD) for MTD is not reached of GNC-039.

This first-in-human study will establish the human safety and radiation dosimetry of the system A amino acid transport substrate, (R)-3-\[F-18\]fluoro-2-methyl-2-(methylamino)propanoic acid (\[F-18\]MeFAMP), for positron emission tomography (PET) imaging of primary and metastatic brain tumors. This study will include 3 cohorts: healthy volunteers for whole body dosimetry estimates (n=6-8, Dosimetry Cohort), patients undergoing evaluation for recurrent high grade glioma after radiation therapy (n=10, high grade glioma (HGG) Cohort), and patients with brain metastases from extra-cranial solid tumors before and after radiation therapy (n=10, Metastasis Cohort). Exploratory assessment of the diagnostic accuracy of MeFAMP for distinguishing recurrent/progressive brain tumors from radiation-related treatment effects will also be performed for subsequent trial design. The study will complete accrual and safety assessment in the Dosimetry Cohort before recruiting for the HGG and Metastasis Cohorts.

This clinical trial tests how well a digital treatment platform using a mobile application works for the delivery of home-based sequential therapy in patients with glioma. Access to specialized neuro-oncology care in the United States for patients with glioma is critically deficient. Care at centers with neuro-oncology specialists is associated with improved survival outcomes, yet many patients have limited access due to distance, disease-related disability, or lack of financial resources. The application provides patients continuous access to their care team in the home setting. A digital treatment platform may increase clinical trial participation and accelerate development of novel therapeutics while addressing a great health disparity in patients with glioma.

The goal of this research study is to determine the best dose of CARv3-TEAM-E T Cells for treating participants with glioblastoma. The name of the treatment intervention used in this research study is: -CARv3-TEAM-E T Cells (or Autologous T lymphocytes).

Sitagliptin, when combined with standard-of-care drug bevacizumab, is being tested to 1) find out if it is effective at treating gliomas that have returned or progressed after treatment, and 2) find out what the highest dose of sitagliptin is appropriate to give when combined with bevacizumab.

The purpose of this research study is to see if a specific type of radiation therapy, called "proton pulsed reduced dose rate" or "PRDR radiotherapy" has any benefits at dose levels and number of fractions thought to be acceptable in earlier research studies. The researchers want to find out what effects (good and bad) PRDR has on people with cancer in the brain called a "recurrent high-grade glioma" meaning that it grows fast, can spread quickly, and it has come back or gotten worse after being treated previously.
