IRDye800CW-BBN PET-NIRF Imaging Guiding Surgery in Patients With Lower Grade Glioma

August 5, 2024 updated by: Deling Li

IRDye800CW-BBN PET-NIRF in Lower Grade Glioma

This is an open-label positron emission tomography/near infrared (PET/NIRF) study to investigate the imaging navigation performance and evaluation efficacy of dual modality imaging probe 68Ga-BBN-IRDye800CW in patients with lower grade glioma. A single dose of 40μg/111-148 Mega-Becquerel (MBq) 68Ga-NOTA-BBN and 1.0- or 2.0- mg/ml IRDye800CW-BBN will be injected intravenously before the operation and intraoperative respectively. Visual and semiquantitative method will be used to assess the PET images and real-time margins localization for surgical navigation.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Lower grade gliomas (WHO grades II and III) are currently diffused disease with variability of tumor behaviors and of challenge to distinguish the margins in white-light microscope during the surgery. An integrated dual-modality approach combining preoperative positron emission tomography imaging with intraoperative optical guidance that target the same tumor biomarker would be of grade help to solve this problem. BBN, with the amino acid sequence of Gln-Trp-Ala-Val-Gly-His-Leu-Met-NH2, has been extensively used for the development of molecular probes for the imaging of gastrin-releasing peptide receptor (GRPR), a member of the G protein-coupled receptor family of bombesin receptors that over-expressed in various types of cancer cells including glioma. For interests in clinical translation of GRPR targeting dual modality probe, an open label dual modality imaging PET/ NIRF study was designed to investigate the imaging guiding performance in lower grade glioma patients. To investigate whether the preoperative PET with BBN can predict the success of the fluorescence guided surgery with same peptide intraoperatively. The sensitivity, specificity and accuracy of fluorescence guided sampling intraoperatively according to the final pathology will be assessed as well.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Standardized uptake value of 68Ga-BBN-IRDye800CW in PET imaging of lower grade gliomas
Time Frame: 1 year
The semiquantitative analysis will be performed by the same person for all the cases, and the standardized uptake value (SUV) of the tracer in lower grade glioma will be measured.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
