Brief Summary:
This is an open-label brain PET/CT (positron emission tomography/computed tomography) study to investigate the diagnostic performance and evaluation efficacy of 68Ga-BNOTA-PRGD2 in glioma patients. A single dose of nearly 111 MBq 68Ga-BNOTA-PRGD2 (≤40 µg BNOTA-PRGD2) will be intravenously injected into patients in suspicion of glioma. Visual and semiquantitative method will be used to assess the PET/CT images. Brain MRI with/without enhancement and 18F-FDG PET/CT will be performed for comparison. The postoperative pathology and integrin αvβ3 and CD34 immunohistochemical stains will also be used for correlation.

Detailed Description:

Integrin αvβ3 is an important member of integrin receptor family and expressed preferentially on various types of tumor cells and the activated endothelial cells of tumor angiogenesis, but not or very low on the quiescent vessel cells and other normal cells. Therefore, the integrin αvβ3 receptor is becoming a valuable target for diagnosis and response evaluation of malignant tumors.

The tri-peptide sequence of arginine-glycine-aspartic acid (RGD) can specifically bind to the integrin αvβ3 receptor. Accordingly, a variety of radio-labeled RGD-based peptides have been developed for non-invasive imaging of integrin αvβ3 receptor expression via positron emission tomography (PET) or single photon emission computed tomography (SPECT). Among all RGD radiotracers, several PET imaging agents, including 18F-Galacto-RGD and 18F-AH111585, have been investigated in clinical trials for tumor diagnosis, and the results demonstrated that both radiotracers allowed the specific imaging of various types of tumors, and the tumor uptake correlated well with the expression of integrin αvβ3. Recently, serial RGD dimeric peptides with PEG linkers have been studied. The new types of RGD peptides showed much higher in vitro integrin αvβ3-binding affinity than the single RGD tri-peptide sequence, and importantly, they exhibited significantly increased tumor uptake and improved in vivo kinetics in animal models. As a representative, 68Ga-BNOTA-PRGD2 could be easily prepared and exhibited excellent in vivo behaviors in animal models. No adverse reactions have been observed in animal models to date.

For the further interests in clinical translation of 68Ga-BNOTA-PRGD2, an open-label brain PET/CT study was designed to investigate the diagnostic performance and evaluation efficacy of 68Ga-BNOTA-PRGD2 in pre-surgery glioma patients.

Arm Intervention/treatment
Experimental: 68Ga-BNOTA-PRGD2
In patients in suspicion of glioma, single bolus of nearly 111 MBq 68Ga-BNOTA-PRGD2 will be intravenously injected 30 minutes before brain PET/CT to determine 68Ga-BNOTA-PRGD2 uptake in tumor and brain.
Drug: 68Ga-BNOTA-PRGD2
Single intravenous bolus injection of nearly 111 MBq 68Ga-BNOTA-PRGD2 at 30 minutes before brain PET/CT scanning.
Other Name: 68Ga-p-SCN-Bn-NOTA-PEG3-RGD2

Primary Outcome Measures :
  1. Semiquantitative measurement of standardized uptake values (SUVs) of lesions [ Time Frame: 1 year ]
    The semiquantitative analysis will be performed by the same person for all cases, and the standardized uptake value (SUV) of each tumor will be measured using a volume of interest (VOI) method.

Secondary Outcome Measures :
  1. Number of participants with adverse events as a measure of safety [ Time Frame: 1 year ]
    Adverse events within 5 days after 68Ga-BNOTA-PRGD2 injection and PET/CT scanning will be collected and analyzed.
