About this study

Official title: Initial Evaluation of Role of Early Interim 18F-FLT PET/CT for Outcome Prediction in Pancreatic Adenocarcinoma

To assess if percentage change in 18F-FLT PET/CT quantitative parameters (SUV max, or SUV peak or proliferative tumor volume) after 2 cycles of neoadjuvant chemotherapy can predict overall survival at 1 and 2 years and progression free survival at 6 months and 1 year in patients with borderline resectable or locally advanced, pancreatic adenocarcinoma.

Read the detailed description

The experimental 18F-FLT-PET/CT is required to be completed before initiation of chemotherapy. Labs and correlative radiology, as directed per clinical care, are required within 30 days prior to 18F-FLT-PET/CT; and 18F-FDG-PET/CT is required within 30 days before the 18F-FLT-PET/CT. Follow-up will comprise 24 months of standard practice treatment and follow up.

Visit 1: Patients will have at least one visit with investigator (or investigator designee) prior to the study to review clinical history and prior treatment of pancreatic adenocarcinoma, and to explain the study. Correlative radiology studies including CT, MRI and 18F FDG-PET/CT as per institutional routine clinical care, and any clinically-directed laboratory tests performed as part of staging must be performed within 30 days of the 18F FLT-PET/CT

Visit 2 (Optional): The 18F-FDG-PET/CT may be done as a research scan, if the patient is unable to obtain a clinically-directed 18F-FDG-PET/CT as part of their clinical care or within 30 days of 18F FLT-PET/CT. The research 18F-FDG-PET/CT, in this instance, will be identical in procedure to the institution's clinical 18F-FDG-PET/CT. The blood glucose level will be < 200 mg/dl, before 18F-FDG injection, which is institutional standard clinical protocol. The following additional patient data will be obtained: histological diagnosis of primary and/or metastatic disease, date of diagnosis of primary and metastatic disease, gender, height, weight (for BMI), ECOG score and confirmation of absence of prior treatment.

Visit 3: Day of 18F-FLT-PET/CT: The patient will have an intravenous line placed in the hand or arm, 18F-FLT-PET/CT will be given by 1-2 minute IV push, and the dose administered will be approximately 5 mCi (+/- 20% dose). After approximately 60 +/- 10 minutes of uptake time, the patient will be positioned supine in the PET/CT scanner for standard whole body PET/CT scan from the skull base to mid-thigh. This scan will take approximately 20-30 min. The window from FLT PET/CT baseline study to initiation of chemotherapy should be no more than 30 days.

Visit 4: Day of Interim 18F-FLT-PET/CT: The interim 18F FLT-PET/CT will be performed after the 2nd cycle of chemotherapy regimen, but before the commencement of 3rd cycle. The second 18F-FLT-PET/CT study must be performed on the same scanner as the first 18F FLT-PET/CT and the imaging protocol described in Visit 3 should be closely followed.

Study duration:

Clinical Follow Up: Standard of care clinical follow-up data will be collected up to 2 years following the end of chemotherapy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Summed Standardized Uptake Value (SUVmax) of Lesion After 2 Cycles of Chemotherapy

    Change in FLT PET/CT SUV Max after 2 cycles of chemotherapy will be compared to baseline (pre-treatment FLT PET/CT SUV Max)

    Measured: Baseline(pre-treatment), 2 cycles after starting chemotherapy (each cycle 14 days)

  2. Change From Baseline in SUV Peak of Lesion After 2 Cycles of Chemotherapy

    Change in FLT PET/CT SUV peak after 2 cycles of chemotherapy will be compared to baseline (pre-treatment FLT PET/CT SUV Peak)

    Measured: Baseline(pre-treatment), 2 cycles after starting chemotherapy (each cycle 14 days)

  3. Change From Baseline in Proliferative Tumor Volume After 2 Cycles Chemotherapy

    Change in FLT PET/CT Proliferative tumor volume after 2 cycles of chemotherapy (compared to pre-treatment FLT PET/CT proliferative tumor volume)

    Measured: Baseline(pre-treatment), 2 cycles after starting chemotherapy (each cycle 14 days)

  4. 1 Year Overall Survival

    Proportion of subjects who were alive at 1 year post-treatment is assessed

    Measured: Baseline(pre-treatment), until date of first observed death, assessed up to 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 3'-deoxy-3'-[F-18] fluorothymidine: [F-18]FLT, Computed Tomography and Positron Emission Tomography in people with Pancreatic Adenocarcinoma, run by University of Texas Southwestern Medical Center 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 10 inclusion and 4 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: finished, as of the sponsor's last update on 8 Nov 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 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?

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?

Yes. Results are posted in the registry (first posted 8 Nov 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change From Baseline in Summed Standardized Uptake Value (SUVmax) of Lesion After 2 Cycles of Chemotherapy (time frame: Baseline(pre-treatment), 2 cycles after starting chemotherapy (each cycle 14 days)). The study lists 5 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 8 Nov 2022.
