68Ga-P16-093 PET/CT Imaging in Glioma Patients

Study Purpose

PSMA is highly expressed on the cell surface of the microvasculature of several solid tumors, including glioma. This makes it a potentially imaging target for the detection and grading of gliomas. This pilot study was designed to evaluate the diagnostic performance of 68Ga-P16-093, a novel radiopharmaceutical targeting PSMA, which was compared with MRI in the same group of glioma patients.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years - 80 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- glioma patients highly suggested by MRI or histologically confirmed; - 68Ga-P16-093 PET/CT and MRI within two weeks; - signed written consent.

Exclusion Criteria:

- known allergy against PSMA; - any medical condition that in the opinion of the investigator may significantly interfere with study compliance.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05569434
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 1/Phase 2

Additional Details

Glioma is the most common primary malignant brain tumor which can be divided into four grades according to different histopathological and molecular biological characteristics.Among them, glioblastoma is one of the most common types of glioma in adults (about 55%). It belongs to WHO Grade IV high-grade glioma, with a high recurrence rate, poor prognosis, and a 5-year survival rate of less than 10%. Prostate-specific membrane antigen (PSMA), as known as folate hydrolase I or glutamate carboxypeptidase II, is overexpressed on the cells of prostatic adenocarcinoma. However, PSMA is also expressed by tumor cells or neovascular endothelial cells of various solid neoplasms, such as glioma. Therefore, PSMA may be an ideal target for the diagnosis of glioma. 68Ga-P16-093, a novel radiopharmaceutical targeting PSMA, with the urea fragment of a conjugate that employs the HBED-CC chelator for labeling with 68Ga(III). The HBED-based chelating ligand binds the 68Ga3+ ion with high affinity in a pseudo-octahedral N2O4 coordination sphere by its two phenolate O, two amino-acetate carboxylate O, and two amino N donor atoms. This pilot study was designed to evaluate the diagnostic performance of 68Ga-P16-093 in the same group of glioma patients, compared with MRI.

Arms & Interventions

Arms

Experimental: 68Ga-P16-093 and MRI scan

Within 1 week, each patient underwent MRI scan and PET/CT scan after intravenous administration of 68Ga-P16-093, respectively.

Interventions

Drug: - 68Ga-P16-093

Intravenous injection of 68Ga-P16-093 with the dosage of 1.5-1.8 MBq (0.04-0.05 mCi)/kg. Tracer doses of 68Ga-P16-093 will be used to image lesions of glioma by PET/CT.
