About this study
Official title: Evaluating in Vivo PARP-1 Expression With 18F-FluorThanatrace Positron Emission Tomography (PET/CT) in Pancreatic Cancer
The investigators plan to enroll 30 evaluable patients with (1) a histological diagnosis of advanced pancreatic ductal adenocarcinoma who have demonstrated at least stable disease following ≥16 weeks of treatment with platinum-based chemotherapy and (2) who have signed consent to participate in a clinical trial that contains PARP inhibitor therapy and are anticipated to receive this treatment or (3) will receive PARP inhibitor therapy as part of their clinical care.
A pre-treatment 18F-FluorThanatrace ([18F]FTT) positron emission tomography/computed tomography (PET/CT) scan will be done prior to the start of treatment with a PARP inhibitor.

PET/CT imaging will be used to evaluate PARP-1 expression in sites of pancreatic cancer using the investigational radiotracer [18F]FTT. This is an observational study in that [18F]FTT PET/CT will not be used to direct treatment decisions. While patients and referring physicians will not be blinded to the [18F]FTT PET/CT results, treatment decisions will be made by the treating physicians based upon clinical criteria.
Patients will undergo approximately 60 minutes of dynamic scanning starting at the time of injection of [18F]FTT. This procedure will be followed by a skull base to mid-thigh scan, starting at approximately 60 minutes post injection. PET/CT imaging sessions will include an injection of approximately 10 mCi (approximate range for most studies is anticipated to be 8-12 mCi) of [18F]FTT. Data will be collected to evaluate uptake of [18F]FTT in sites of pancreatic cancer, which will be compared with PARP-1 expression in tissue, when available.
All 30 evaluable patients are expected to start PARP inhibitor therapy following the [18F]FTT PET/CT scan. It is expected that due to patient preference and time considerations, approximately 24 patients (80%) will also undergo a second (optional) scan that will be performed approximately 3 weeks (± 1 week) after therapy has started. The second scan is obtained to evaluate whether the PARP inhibitor therapy decreases [18F]FTT uptake, which would suggest PARP blocking by the therapy.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing [18F]FluorThanatrace ([18F]FTT) in people with Pancreatic Cancer, run by Abramson Cancer Center at Penn Medicine at 1 site in United States.
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 5 inclusion and 3 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 12 Jun 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 United States. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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: Early analysis of images after 6 patients showed no activity of the radiotracer in this patient population.). 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?
Number of Adverse Events (time frame: 3 years). 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 12 Jun 2024.
