Glioblastoma Clinical Trials

Previous evidence has indicated that resection for recurrent glioblastoma might benefit the prognosis of these patients in terms of overall survival. However, the demonstrated safety profile of this approach is contradictory in the literature and the specific benefits in distinct clinical and molecular patient subgroups remains ill-defined. The aim of this study, therefore, is to compare the effects of resection and best oncological treatment for recurrent glioblastoma as a whole and in clinically important subgroups. This study is an international, multicenter, prospective observational cohort study. Recurrent glioblastoma patients will undergo tumor resection or best oncological treatment at a 1:1 ratio as decided by the tumor board. Primary endpoints are: 1) proportion of patients with NIHSS (National Institute of Health Stroke Scale) deterioration at 6 weeks after surgery and 2) overall survival. Secondary endpoints are: 1) progression-free survival (PFS), 2) NIHSS deterioration at 3 months and 6 months after surgery, 3) health-related quality of life (HRQoL) at 6 weeks, 3 months, and 6 months after surgery, and 4) frequency and severity of Serious Adverse Events (SAEs) in each arm. Estimated total duration of the study is 5 years. Patient inclusion is 4 years, follow-up is 1 year. The study has been approved by the Medical Ethics Committee (METC Zuid-West Holland/Erasmus Medical Center; MEC-2020-0812). The results will be published in peer-reviewed academic journals and disseminated to patient organisations and media. Read Less

This is an open-label, multi-center Phase 0 study with an expansion phase that will enroll up to 24 participants with newly-diagnosed glioblastoma and up to 18 recurrent glioma participants with IDH mutation and ATRX loss. The trial will be composed of a Phase 0 component (subdivided into Arm A and B) and a therapeutic expansion phase. Patients with tumors demonstrating a positive PK Response (in Arm A) or a positive PD Response (in Arm B) of the Phase 0 component of the study will graduate to a therapeutic expansion phase that combines therapeutic dosing of niraparib plus standard-of-care fractionated radiotherapy (in Arm A) or niraparib monotherapy (in Arm B) until progression of disease.

A greater extent of resection of the contrast-enhancing (CE) tumor part has been associated with improved outcomes in high-grade glioma patients. Recent results suggest that resection of the non-contrast-enhancing (NCE) part might yield even better survival outcomes (supramaximal resection, SMR). Therefore, this study evaluates the efficacy and safety of SMR with and without mapping techniques in HGG patients in terms of survival, functional, neurological, cognitive, and quality of life outcomes. Furthermore, it evaluates which patients benefit the most from SMR, and how they could be identified preoperatively. This study is an international, multicenter, prospective, 2-arm cohort study of observational nature. Consecutive HGG patients will be operated with supramaximal resection or maximal resection at a 1:3 ratio. Primary endpoints are: 1) overall survival and 2) proportion of patients with NIHSS (National Institute of Health Stroke Scale) deterioration at 6 weeks, 3 months, and 6 months postoperatively. Secondary endpoints are 1) residual CE and NCE tumor volume on postoperative T1-contrast and FLAIR MRI scans 2) progression-free survival; 3) onco-functional outcome, and 4) quality of life at 6 weeks, 3 months, and 6 months postoperatively. The study will be carried out by the centers affiliated with the European and North American Consortium and Registry for Intraoperative Mapping (ENCRAM). Read Less

Resection of glioblastoma in or near functional brain tissue is challenging because of the proximity of important structures to the tumor site. To pursue maximal resection in a safe manner, mapping methods have been developed to test for motor and language function during the operation. Previous evidence suggests that these techniques are beneficial for maximum safe resection in newly diagnosed grade 2-4 astrocytoma, grade 2-3 oligodendroglioma, and recently, glioblastoma. However, their effects in recurrent glioblastoma are still poorly understood. The aim of this study, therefore, is to compare the effects of awake mapping and asleep mapping with no mapping in resections for recurrent glioblastoma. This study is an international, multicenter, prospective 3-arm cohort study of observational nature. Recurrent glioblastoma patients will be operated with mapping or no mapping techniques with a 1:1 ratio. Primary endpoints are: 1) proportion of patients with NIHSS (National Institute of Health Stroke Scale) deterioration at 6 weeks, 3 months, and 6 months after surgery and 2) residual tumor volume of the contrast-enhancing and non-contrast-enhancing part as assessed by a neuroradiologist on postoperative contrast MRI scans. Secondary endpoints are: 1) overall survival (OS), 2) progression-free survival (PFS), 4) health-related quality of life (HRQoL) at 6 weeks, 3 months, and 6 months after surgery, and 4) frequency and severity of Serious Adverse Events (SAEs) in each arm. Estimated total duration of the study is 5 years. Patient inclusion is 4 years, follow-up is 1 year.

This is an open-label phase 1 study to assess the safety and feasibility of autologous T cells co-expressing two CARs targeting the cryptic EGFR and IL13Ra2 (referred to as "CART-EGFR-IL13Ra2 cells") in patients with EGFR-amplified glioblastoma, IDH-wildtype that has recurred following prior radiotherapy.

Primary brain cancer kills up to 10,000 Americans a year. These brain tumors are typically treated by surgery, radiation therapy and chemotherapy, either individually or in combination. Present therapies are inadequate, as evidenced by the low 5-year survival rate for brain cancer patients, with median survival at approximately 12 months. Glioma is the most common form of primary brain cancer, afflicting approximately 7,000 patients in the United States each year. These highly malignant cancers remain a significant unmet clinical need in oncology. GBM often has a high expression EFGR (Epidermal Growth Factor Receptor) which is blocked by Cetuximab (CTX). The investigators have recently completed a separate Phase I clinical trial using superselective intra-arterial cerebral infusion (SIACI) of CTX after blood brain barrier disruption (BBBD) for recurrent GBM (Chakraborty et al, in revision, Journal of Neurooncology). The investigators found that intra-arterial infusion of CTX is well tolerated with few adverse effects. The investigators hypothesize that in patients with newly diagnosed GBM, repeated SIACI of this drug after BBBD will be safe and efficacious for our patients when combined with standard chemoradiation (STUPP protocol). This trial will be a non-randomized open label Phase I/II clinical trial. In addition to standard chemotherapy and radiation therapy (STUPP protocol) the patient will be given CTX intra-arterially after BBBD for a total of three doses at approximately post surgery days 30, 120 and 210.
