Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Nal-IRI, Ciprofloxacin and Paclitaxel in people with PDAC - Pancreatic Ductal Adenocarcinoma, run by GERCOR - Multidisciplinary Oncology Cooperative Group at 12 sites 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 22 inclusion and 19 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: opening soon, as of the sponsor's last update on 1 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 12 sites 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.
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?
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 Cindy NEUZILLET, MD (+33 (0) 1 47 11 15 15 ext. 7129, cindy.neuzillet@curie.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
6-month progression-free survival (PFS) rate post randomization Step 1 (R1) in Arm 1A (time frame: 6 months). 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 1 Jul 2025.
