Recurrent High Grade Glioma

Glioblastoma (GBM), WHO grade IV glioma, represents the majority of adult malignant primary brain tumors, with an incidence of 2-3 per 100,000 person-years. The survival for GBM has increased in the last decade but is still low with a median survival of 15-18 months. Recurrence after initial standard therapy, radiation therapy and chemotherapy with temozolomide, few options are available. Even with further therapy, median progression free survival at 6 months after first relapse (PFS-6) is only 15%. Similarly, anaplastic astrocytoma and anaplastic oligodendroglioma, grade III gliomas, once recurrent after radiation therapy and first-line chemotherapy, have identical therapeutic options and poor outcomes with PFS-6 of 31%. Temozolomide (TMZ) has a favorable side effect profile and is available orally, however, cytotoxicity occurs. Metronomic temozolomide at low doses on a continuous schedule, have demonstrated better survival in studies. This study will determine the recommended dose and the side effects of PCI-24781/Abexinostat with metronomic temozolomide.

This is a Phase 1 open label study designed to assess the safety and tolerability of the oncolytic herpes simplex virus 1 (oHSV1) study drug, MVR-C5252, administered intratumorally by convection-enhanced delivery (CED) in patients with recurrent high-grade glioma. Once the safety and maximum tolerated dose (MTD) is established in the dose escalation portion of the trial, a dose expansion cohort at the recommended phase 2 dose (RP2D) in patients with isocitrate dehydrogenase (IDH) wildtype recurrent glioblastoma (GBM) will evaluate preliminary efficacy of the study drug.

This is a draft, ClinicalTrials.gov-style example record for a first-in-human Phase 1 study evaluating locoregional administration of dual-targeting chimeric antigen receptor natural killer (CAR-NK) cells in adults with recurrent or progressive glioblastoma (GBM) or other high-grade glioma (HGG). Participants will undergo tumor antigen profiling for IL13Rα2, EGFR/EGFRvIII, and B7-H3 (CD276). Based on this assessment, each participant will receive the most suitable dual-target CAR construct to reduce antigen-escape risk.

This clinical trial aims to investigate the efficiency and safety of laser interstitial thermal therapy (LITT) in recurrent high-grade glioma (rHGG) patients. The main questions it aims to answer are: * The LITT would increase the progression-free survival and overall survival of rHGG patients compared to other treatments. * The LITT is safe and applicable to rHGG patients Participants will be randomized to the intervention group (LITT) or control group at a ratio of 2:1. The intervention group patients will receive LITT. The control group will be treated with any other treatment. The primary outcome of this trial is progression-free survival. The estimated sample size is 135, 90 in the LITT group and 45 in the control group.

This is a single center Phase I study of a new adjuvant CD200 activation receptor ligand, CD200AR-L, in combination with imiquimod and GBM6-AD vaccine to treat malignant glioma in children and young adults. The primary objective of this study is to determine the maximum tolerated dose (MTD) of CD200AR-L when given with a fixed dose of GBM6-AD vaccine, imiquimod, and a single dose of radiation for patients with recurrent High Grade Glioma (HGG) or following standard of care therapy radiation therapy for newly diagnosed Newly Diagnosed Diffuse Midline Glioma/Diffuse Intrinsic Pontine Glioma (DIPG/DMG).
