About this study
The pre-operative assessment of intra-abdominal tumor load in patients with epithelial ovarian cancer (EOC) remains unreliable with standard imaging modalities. The use of tumor targeted imaging, such as folate receptor (FR)-targeted positron emission tomography (PET) imaging could aid in the preoperative assessment of metastatic tumor load.
This study aims to evaluate the safety and tolerability, and pharmacokinetics of the [18F]fluoro-PEG-folate PET tracer and to assess the sensitivity and specificity of a [18F]fluoro-PEG-folate PET/CT scan for the preoperative detection of intra-abdominal metastatic lesions in patients with advanced stage epithelial ovarian cancer.

A dynamic FR-targeted PET scan, a low-dose CT scan without contrast agents, and a static FR-targeted PET scan will be obtained
| Study group | Role | What they receive |
|---|---|---|
| [18F]fluoro-PEG-folate PET/CT scan | Experimental | Patients with FIGO stage IIIB/IIIC epithelial ovarian cancer, 185 MBq of [18F]fluoro-PEG-folate. Receives: Diagnostic Test: [18F]fluoro-PEG-folate PET/CT scan |
What is being measured
The primary outcome is the main question the study is designed to answer.
Tolerability of the [18F]fluoro-PEG-folate PET tracer
To assess the tolerability of the [18F]fluoro-PEG-folate PET tracer vital signs will be recorded every 15 minutes starting directly before administration and continued up to two hours after dosing. The endpoint for this study is the number of patients whose vital signs stayed within a normal range of their baseline.
Measured: From administration up to two hours after administration
Arterial plasma input curve of the [18F]fluoro-PEG-folate tracer
Blood samples will be collected to determine the arterial plasma input curve of the tracer.
Measured: At regular intervals up to 90 minutes post injection of the tracer.
Pharmacokinetic distribution of the [18F]fluoro-PEG-folate tracer
Blood samples will be collected to determine the pharmacokinetic distribution of the tracer.
Measured: At regular intervals up to 90 minutes post injection of the tracer.
Safety of the [18F]fluoro-PEG-folate PET tracer
Total number of AEs and SAEs that occur during the observation period.
Measured: Up to six weeks after the injection of the tracer.
Secondary outcomes (1)
Sensitivity and specificity
Sensitivity and specificity of the FR-targeted PET/CT scan for the detection of metastatic EOC lesions. Postoperative histopathology will serve as the gold standard.
Measured: Up to 6 weeks after the FR-targeted PET/CT scan.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing [18F]fluoro-PEG-folate PET/CT scan in people with Epithelial Ovarian Cancer, run by Lioe-Fee de Geus-Oei, MD PhD at 1 site in Netherlands.
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 9 inclusion and 11 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: stopped early, as of the sponsor's last update on 15 Mar 2024. 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 Netherlands. 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 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.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: Reached the stop criteria after the interim analysis). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Tolerability of the [18F]fluoro-PEG-folate PET tracer (time frame: From administration up to two hours after administration). 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?
On the ClinicalTrials.gov record for NCT05215496, which also lists 1 linked publication.
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 15 Mar 2024; AzTrials last refreshed its copy on 7 Nov 2026.
