About this study
Official title: 68Ga-P16-093 PET/CT Imaging in Primary and Recurrent Glioma Patients
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.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
68Ga-P16-093Drug
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.
| Study group | Role | What they receive |
|---|---|---|

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing 68Ga-P16-093 in people with Glioma, run by Peking Union Medical College Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 6 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Zhaohui Zhu, MD (86-13611093752, 13611093752@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Diagnostic performance (time frame: through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2022.
