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

January 16, 2018 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.

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/ NIFR study was designed to investigate the imaging guiding performance in lower grade glioma patients.

EXPERIMENTAL: 68Ga-BBN-IRDye800CW PET/NIRF
The patients were injected with 40μg/111-148 Mega-Becquerel (MBq) 68Ga-BBN-IRDye800CW in one dose intravenously and then underwent PET scan 30 min later before the operation and intraoperative 1.0 or 2.0 mg/ml BBN-IRDye800CW injected intravenously for near-infrared (NIR) fluorescent imaging-guided surgery.
