Multimodality MRI and Liquid Biopsy in GBM

Glioblastoma Multiforme Clinical Trial

Official title: Multimodality MRI for Quantification of Tumor-associated Macrophages and Prediction of Somatic Mutation Detectability in Cell-free DNA in Adult Patients With Glioblastoma

Status Withdrawn

Clinical Trial Summary

Patients with a new diagnosis of high-grade glioma based on MRI, who are considered surgical candidates determined by neurosurgeons or patients with recurrent glioblastoma with the initial diagnosis of glioblastoma (histologic or molecular proof) and recommended for clinically surgical resection may be eligible for this study. Subjects may participate in this study if they are at least 18 years of age. Ferumoxytol-enhanced MRI will be used to quantify tumor-associated macrophages. This is a non-therapeutic trial in that imaging will not be used to direct treatment decisions. The blood draw is being completed to evaluate cell-free circulating tumor DNA (cfDNA) and cell-free tumor DNA (ctDNA).

Clinical Trial Description

This is a pilot study in subjects with a new diagnosis of high-grade glioma based on classic MRI appearance who are considered surgical candidates and patients with histologically proven diagnosis of glioblastoma (GB) who have completed chemoradiation and now have new contrast-enhancing lesions or lesions showing increased enhancement ( 25% increase) who are recommended for a clinical surgical resection. Subjects may participate in this study if they are at least 18 years of age, most participants will be receiving care at the clinical practices of the University of Pennsylvania. Subjects who come to the University of Pennsylvania for diagnosis and/or treatment of GB and who meet the study inclusion criteria may be approached by study personnel for recruitment into this study. Subjects will be approached about study participation regardless of race or ethnic background. Investigators anticipate enrolling up to 30 participants. Subjects who consent but do not complete the study imaging will be considered not evaluable and will be replaced. Accrual will likely occur over approximately 2 years. After undergoing screening assessments and verifying eligibility for study participation subjects will undergo a research ferumoxytol-enhanced MRI of the brain and blood draws for liquid biopsy. ;
