Glioblastoma Clinical Trial
Official title:
Towards In-Vivo, Intraoperative Image Guided Brain Tumor Margin Assessment With Quantitative Oblique Back Illumination Microscopy
This early phase I trial tests the safety and reliability of an investigational imaging technique called quantitative oblique back illumination microscopy (qOBM) during brain surgery for detecting brain tumors and brain tumor margins in patients with glioblastoma, astrocytoma, or oligodendroglioma. Surgical margins refer to the edge or border of the tissue removed in cancer surgery. qOBM may be able to assess and reveal brain tumor surgical margins in a more safe and reliable manner.

Eligibility | Inclusion Criteria: - Age >= 18 years - Craniotomy is indicated for tumor management - Surgery planned for 14 or fewer days from enrollment - Evidence of a personally signed informed consent indicating that the subject is aware of the neoplastic nature of the disease and has been informed of the procedures to be followed, the experimental nature of the device evaluation, alternatives, potential risks and discomforts, potential benefits, and other pertinent aspects of study participation. - A newly discovered brain lesion requiring surgery who imaging is consistent with a new glioblastoma, astrocytoma, or oligodendroglioma or with a progressive histologically proven glioblastoma, astrocytoma, or oligodendroglioma whose management required surgery. Exclusion Criteria: An individual who meets any of the following criteria will be excluded from participation in this study: - Patients who are undergoing needle biopsy only - Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. |

Primary | Incidence of Adverse Events | Adverse events will be assessed and graded according to the Common Terminology Criteria for Adverse Events version 5.0. Summary statistics will be reported for categorical variables using descriptive statistics. Patient demographics will be summarized descriptively. 95% confidence intervals will be reported, unless otherwise specified. All tests will be two-sided. | Up to 3 years | |
Primary | Reliability of Quantitative Oblique Back Illumination Microscopy Device Determined by Frequency Distribution | Robustness will be defined as the device's ability to clearly reveal relevant cellular and subcellular histological structures that can lead to clinically actionable outcomes, is determined. Using standard clinical techniques such as loupe magnification, surgical microscopy, histology, intraoperative ultrasound, and postoperative magnetic resonance imaging (MRI) as general points of historical reference.
Summary statistics will be reported for categorical variables using descriptive statistics measures of frequency. Patient demographics will be summarized descriptively. All tests will be two-sided. |
