About this study
Official title: Comparison of the Detection Efficiencies of Al18F-PSMA-617 and 68Ga-PSMA-617 PET/CT in Patients With Prostate Cancer
18F-labeled prostate-specific membrane antigen (PSMA) ligand-positron emission tomography (PET) offers advantages over 68Ga-labeled PSMA ligands. Al18F-PSMA-617 is a novel 18F-PSMA compound used for prostate cancer (PCa) imaging. This pilot study was prospectively designed to compare the lesion detectability of Al18F-PSMA-617 and related 68Ga-PSMA-617 PET/CT in patients with PCa
Read the detailed description
Prostate cancer (PC) is one of the most common malignancies worldwide in men, with persistently high numbers dying from this disease. Due to low levels of glycolysis in prostate cancer cell, the uses of 18F-FDG PET/CT to detect prostate cancer and its metastases are limited. Prostate specific membrane antigen (PSMA), as known as folate hydrolase I or glutamate carboxypeptidase II, is overexpressed on the cells of prostatic adenocarcinoma. Various low molecular weight radiopharmaceuticals targeting PSMA such as PSMA-617, PSMA-11 for 68Ga-labeling have been developed. 68Ga-PSMA PET/CT has demonstrated desirable sensitivity and specificity in the detection of prostate cancer lesions, which can find many micro lesions that cannot be identified by CT, MRI and bone scan. Al18F-PSMA-617 is a novel radiopharmaceutical targeting PSMA. Liu T et.al had demonstrated that Al18F-PSMA-617 accumulates specifically in PSMA-positive tumors with high binding affinity and selectivity. The first in-human evaluation of Al18F-PSMA-617 in a small PCa sample size also confirmed the good detectability of tumor lesions. This pilot study was prospectively designed to evaluate the early dynamic distribution of Al18F-PSMA-617 compared with 68Ga-PSMA-617 in the same group of prostate cancer patients.

What is being measured
The primary outcome is the main question the study is designed to answer.
Time-activity curves
During the early dynamic Al18F-PSMA-617 PET imaging, the SUVmax of PCa lesions, the SUVmean of the normal tissues such as the prostate gland , the common iliac artery , the bladder, and the gluteus maximus were measured.Time-activity curves(TACs) describing SUVmax versus time of tumor lesion and areas with physiologic tracer uptake were generated.
Measured: through study completion, an average of 1 year
Kinetic parameters
Based on dynamic Al18F-PSMA-617 PET imaging, tracer kinetics(k1,k2,k3,k4,ki ) in tumor and normal tissues were generated by means of a two-tissue irreversible compartment model and Patlak graphical analysis.
Measured: through study completion, an average of 1 year
Differences in lesion detection at different imaging time point
In addition to the early dynamic images, we also performed whole-body delayed imaging at 2h and 4h after injection of Al18F-PSMA-617.The differences in lesion detectability at different time point were compared in order to determine the optimal imaging time.
Measured: through study completion, an average of 1 year

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Al18F-PSMA-617 and 68Ga-PSMA-617 in people with Prostate Cancer, 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 1 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 3 May 2023. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 Li Huo, MD (86-13910801986, huoli@pumch.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Time-activity curves (time frame: through study completion, an average of 1 year). The study lists 4 primary outcomes in all. 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 3 May 2023.
