Topotecan Using Convection-Enhanced Delivery (CED) in High Grade Glioma
Description

Topotecan is a FDA-approved drug when given by intravenous injection, but it is not effective against brain tumors when given intravenously. The Cleveland Multiport Catheter is a new, investigational device that will be used to deliver topotecan directly into participants' brain tumors. One purpose of this study is to determine whether the Cleveland Multiport Catheter can be used effectively and safely to deliver topotecan directly into brain tumors. This study will also evaluate different doses of topotecan that can be delivered to a participant's brain tumor with use of the Cleveland Multiport Catheter, and it will also examine how their tumor responds to treatment with topotecan.

Memory-Enriched T Cells in Treating Patients With Recurrent or Refractory Grade III-IV Glioma
Description

This phase I trial studies the side effects and best dose of memory-enriched T cells in treating patients with grade II-IV glioma that has come back (recurrent) or does not respond to treatment (refractory). Memory enriched T cells such as HER2(EQ)BBζ/CD19t+ T cells may enter and express its genes in immune cells. Immune cells can be engineered to kill glioma cells in the laboratory by inserting a piece of deoxyribonucleic acid (DNA) into the immune cells that allows them to recognize glioma cells. A vector called lentivirus is used to carry the piece of DNA into the immune cell. It is not known whether these immune cells will kill glioma tumor cells when given to patients.

This study was terminated early due to funding issues. At the time of termination, the study was still in Phase 1 and no MTD for the combination of CTO and bevacizumab had been determined for this population. Phase 2 will not proceed.

RECRUITING
Anti-GARP Chimeric Antigen Receptor T Cell Therapy for the Treatment of Recurrent Grade III or IV Gliomas
Description

This phase I trial tests the safety, side effects, and best dose of anti-glycoprotein-A repetitions predominant (GARP) chimeric antigen receptor (CAR) T cell therapy and how well it works in treating patients with grade III or IV gliomas that have come back after a period of improvement (recurrent). CAR T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack tumor cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein, such as GARP, on the patient's tumor cells is added to the T cells in the laboratory. The special receptor is called a CAR. Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain tumors. Giving anti-GARP CAR T cell therapy may be safe, tolerable, and/or effective in treating patients with recurrent grade III or IV gliomas.

Chronic CED of TPT for Recurrent Malignant Glioma
Description

The primary goal of this study is to establish the safety of chronic Convection Enhanced Delivery (CED) of the chemotherapeutic drug Topotecan for patients with recurrent malignant glioma that harbors the Isocitrate Dehydrogenase mutation (IDH-mut). The secondary goal of the study is to study drug distribution and assess the tumor response to prolonged continuous CED of Topotecan. Convection Enhanced Delivery is a novel method of drug delivery that allows administration of a drug directly to the brain. In CED, a drug pump is placed under the skin in the chest or abdominal region. The pump is connected to a catheter that is tunneled underneath the skin to the brain. The tip of the catheter then infuses Topotecan directly onto the brain tumor. There will be a total of four treatment infusions over the course of 23-29 days, with a 5-7-day rest period between each infusion. Throughout this period, patients' health will be monitored through imaging, blood draws, and regular exams. At the end of the treatment period, the pump will be removed, followed by resection of the tumor. Patients will be followed for the duration of their lives. This is the investigator's second clinical trial studying CED of TPT in recurrent glioma. In the prior Phase 1b trial, chronic pulsatile CED safely and effectively delivered Topotecan to patients with IDH mutant recurrent Glioblastoma (WHO grade 4).

Safety and Efficacy Study in Recurrent or Progressive Grade III or IV IDH1 Mutated Glioma
Description

This multi-site, Phase 1/2a clinical trial is an open-label study to identify the safety, pharmacokinetics, and efficacy of a repeated dose regimen of NEO100 (perillyl alcohol) for the treatment of patients with radiographically-confirmed progression of Grade IV glioma or recurrent primary or secondary Grade IV glioma. The study will have two phases, Phase 1 and Phase 2a. Phase 1 is a standard cohort dose escalation 3+3 design used to determine the maximum tolerated dose for Phase 2a. There will be up to 24 patients enrolled in Phase 1. There will be 25 patients enrolled in Phase 2a. For both phases of the study, NEO100 will be self-administered four times daily for a 28-day treatment cycles until disease progression, death or patient withdraw from study for any reason, whichever occurs first. Version 10 of the protocol changed the inclusion criteria for Phase 2a to limit inclusion to those patients with progressive or recurrent primary or secondary Grade IV gliomas expressing IDH1 mutations. Prior to the protocol amendment, 4 patients were enrolled who were IDH1 wild-type. Therefore, an additional 28 patients will be recruited for a total of 32 patients enrolled into Phase 2a of this study to have 35 evaluable cases. Version 12 of the protocol expanded the inclusion criteria for Phase 2a to include those patients with progressive or recurrent Grade III Astrocytoma expressing IDH1 mutations. Review of the literature specific to these patients found the same expected time to progression and death. As a result, the number of patients to enroll remains 32 to have 35 evaluable cases.

Protein Phosphatase 2A Inhibitor, in Recurrent Glioblastoma
Description

Background: The brain is separated from the rest of the blood stream by the blood-brain barrier. This is like a filter that protects the brain. But is also a challenge when medicines need to get into the brain. Researchers want to give the new drug LB100 to people before brain tumor surgery. They will measure how much LB100 is in the blood and how much gets into the brain. This may help with the use of LB100 to treat brain tumors in the future. Objective: To see if LB100 can pass into the brain. Eligibility: People at least 18 years old with a brain tumor that requires surgery. Design: Participants will be screened with: Physical exam Medical history Blood tests Neurosurgery evaluation Scans Heart tests Tumor sample. This can be from a previous procedure. Participants will have their brain surgery at the Clinical Center. Participants will get a dose of the study drug through a plastic tube in a vein for 2 hours during surgery. Participants will have blood taken 7 times in the 8 hours after getting the study drug. Tumor samples will be taken during surgery. Participants will have a heart test after getting the study drug. Sticky pads on the skin will measure electrical activity of the heart. Two-three weeks after leaving the hospital, participants will have a follow-up visit. They will have a physical exam and blood tests. One month after surgery, they will be contacted in person or by phone to see how they are doing.
