What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
[68Ga]Ga-ELI421 injectionDrug
Administration Protocol: A single rapid intravenous bolus injection of [68Ga]Ga-ELI421 injection at a radioactivity dose of about 185 MBq (5 mCi), followed by catheter flushing with approximately 10 mL of 0.9% sterile normal saline. Static scanning and/or dynamic scanning Whole-body PET Imaging will be performed. PSMA PET imaging will be performed in accordance with routine clinical practice.

What is being measured
The primary outcome is the main question the study is designed to answer.
Adverse Event (AE)
Any abnormality, medication, or treatment after dosing shall be documented as an adverse event and concomitant medication / non-pharmacological treatment. All adverse events shall be followed up until resolution, stabilization or remission of symptoms, or until abnormal laboratory values return to normal, baseline or a stable state, or until a reasonable explanation is obtained (e.g., loss to follow-up, death).
Measured: Day1, Day2-3
Secondary outcomes (3)
Lesion uptake value
ROIs shall be delineated to calculate the percentage injected dose (%ID), mean standardized uptake value (SUVmean), and retention time of target organs/tissues at various scanning time points.
Measured: Day1
Absorbed dose
Absorbed dose of target organs/tissues and total-body effective dose.
Measured: Day1
Diagnostic performance
Diagnostic performance of [⁶⁸Ga]Ga-ELI421 for lesion detection compared with PSMA PET, including the number of lesions and diagnostic performance indicators such as accuracy, sensitivity, and specificity.
Measured: Day1

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing [68Ga]Ga-ELI421 injection in people with Prostate Cancer, run by Union Hospital, Tongji Medical College, Huazhong University of Science and Technology 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 7 inclusion and 6 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: looking for participants now, as of the sponsor's last update on 8 Jul 2026. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Xiaoli Lan (+86-2783692633, hzslxl@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Adverse Event (AE) (time frame: Day1, Day2-3). 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 8 Jul 2026; AzTrials last refreshed its copy on 26 Oct 2026.
