Trial summary

The proposal aims at determining whether liquid biopsy approaches are valid in the diagnosis of pancreatic cancer. Step1 will test 3 CTC isolation methods and analyse by flow cytometry the presence of onco-exosomes in the culture media of pancreatic cell lines. Read more about this study

About this study

The proposal aims at determining whether liquid biopsy approaches are valid in the diagnosis of pancreatic cancer. Step1 will test 3 CTC isolation methods and analyse by flow cytometry the presence of onco-exosomes in the culture media of pancreatic cell lines. Step 2 will examine the diagnostic accuracy of these blood tumor elements for the diagnosis of cancer of patients with PDAC suspicion or recent diagnosis and their value for disease monitoring.

Read the detailed description

Pancreatic ductal adenocarcinoma (PDAC) incidence has increased with a high rate during the past few years (+4.7% per year between 2005 and 2012, source InfoCancer 2013). No cure is currently available for this deadly disease, with an overall survival <5%. Survival can reach 20% when surgery is possible, giving the best chance to the patients. If patients present locally advance disease, it is crucial to quickly establish resectability to avoid unneeded and even deleterious surgery in patients with metastatic stages. It is also important to increase the rate of true R0 resection with effective preoperative therapy. However, when the cancer is suspected, neoadjuvant chemotherapies are often delayed because the mandatory histologic proof is difficult to make with non-informative biopsies. It is necessary to find new markers to help for rapid diagnosis that could allow neoadjuvant therapies and surgery when anatomo-pathologic proof is not available. New developments in the field of liquid biopsy hold great promise in providing valuable information for diagnosis assistance. The project will be run in two steps. First, several methods will be compared for tumor cell recovery after cell spiking in blood of non-cancer patients and pancreatic cell line onco-exosomes will characterized by flow cytometry. Second the best method will be used to detect and enumerate CTCs in 20 PDAC patients and 20 non-cancer patients. In parallel GPC1+ exosomes from patients' plasmas will be quantified. Diagnosis accuracy will be established and compared. Correlations between circulating tumor elements presence and clinical and biological parameters will be evaluated at the time of the diagnosis. Patient clinical outcome will be assessed according to initial circulating element quantification.

What is being measured

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

  1. Step 1: sensitivity of CTC detection with 3 methods in cell spiking experiments

    Measured: 6 months

  2. Step 2: diagnostic accuracy of the best CTC detection method and onco-exosome quantification for pancreatic adenocarcinoma diagnosis.

    Measured: 18 months

Secondary outcomes (2)
  1. Step 1: reproducibility of CTC detection with the 3 methods

    Estimation with bilateral confidence interval of 95%. A mixed affect linear regression will be operated to obtain this estimation.

    Measured: 6 months

  2. Step 2: correlation between CTCs presence and numbers or onco-exosome concentration with clinical and biological parameters and with patient clinical outcome

    Measured: 18 months

Questions about this trial

What is this clinical trial studying?

An observational study of Pancreatic Ductal Adenocarcinoma (PDAC), run by University Hospital, Bordeaux at 1 site in France.

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 4 inclusion and 5 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 10 Apr 2018. 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 France. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Step 1: sensitivity of CTC detection with 3 methods in cell spiking experiments (time frame: 6 months). The study lists 2 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 10 Apr 2018.
