274 active trials for Glioblastoma

Patient-derived Glioma Stem Cell Organoids

Rationale: Glioblastoma (GM) is the most frequent incurable adult brain tumor with median survival of 15 months after diagnosis, despite extensive treatment with surgery, radiation therapy and chemotherapy. Tumor recurrence is inevitable after which life prolonging therapies are no longer available. The development of new treatments for GM is being hampered by inter-and intratumoral heterogeneity of tumors and their microenvironment, which currently cannot be predicted accurately with current diagnostics. Objective: To establish primary patient derived organoid cultures from GM to study mechanisms that contribute to aggressive tumor growth and treatment resistance in primary and recurrent GM. Study design: Preclinical study, using patient derived glioblastoma tissue. Study population: Patients 18 years or older, with newly diagnosed glioblastoma. Main study parameters/endpoints: Intra-and inter organoid genetic and epigenetic heterogeneity that is representative for GM. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Minimal burden, since the biopsies are part of a regular neurosurgical procedure (debulking); which intends to eradicate the macroscopical tumorload in order to optimize survival benefit. The tissue (biopsy) that will be used for this trial is part of the tumor tissue that is resected during the standard debulking. Benefit: no benefit for the patient.

SJDAWN: St. Jude Children's Research Hospital Phase 1 Study Evaluating Molecularly-Driven Doublet Therapies for Children and Young Adults With Recurrent Brain Tumors

Approximately 90% of children with malignant brain tumors that have recurred or relapsed after receiving conventional therapy will die of disease. Despite this terrible and frustrating outcome, continued treatment of this population remains fundamental to improving cure rates. Studying this relapsed population will help unearth clues to why conventional therapy fails and how cancers continue to resist modern advances. Moreover, improvements in the treatment of this relapsed population will lead to improvements in upfront therapy and reduce the chance of relapse for all. Novel therapy and, more importantly, novel approaches are sorely needed. This trial proposes a new approach that evaluates rational combination therapies of novel agents based on tumor type and molecular characteristics of these diseases. The investigators hypothesize that the use of two predictably active drugs (a doublet) will increase the chance of clinical efficacy. The purpose of this trial is to perform a limited dose escalation study of multiple doublets to evaluate the safety and tolerability of these combinations followed by a small expansion cohort to detect preliminary efficacy. In addition, a more extensive and robust molecular analysis of all the participant samples will be performed as part of the trial such that we can refine the molecular classification and better inform on potential response to therapy. In this manner the tolerability of combinations can be evaluated on a small but relevant population and the chance of detecting antitumor activity is potentially increased. Furthermore, the goal of the complementary molecular characterization will be to eventually match the therapy with better predictive biomarkers. PRIMARY OBJECTIVES: To determine the safety and tolerability and estimate the maximum tolerated dose/recommended phase 2 dose (MTD/RP2D) of combination treatment by stratum. To characterize the pharmacokinetics of combination treatment by stratum. SECONDARY OBJECTIVE: To estimate the rate and duration of objective response and progression free survival (PFS) by stratum.
