About this study

90 % of the patients with bile duct cancer are not justifiable of a surgical resection with curative aim for oncologic reasons ( metastatic extensions), for reasons of resectability (canalar extension, vascular) or still for surgically reasons (age, comorbidity).

The palliative care of these patients consists at first in assuring an effective biliary drainage, infectious complications being one of the main causes of death. The biliary drainage allows to improve the survival of these patients. It bases by the implementation, by the endoscopic or percutaneous way of biliary, generally metallic prosthesis the duration of average permeability of which is of approximately 6 months.

The standard oncologic treatment is the administration of a chemotherapy exclusive or associated with a radiotherapy. The radiotherapy and the radio chemotherapy did not show efficiency on the survival superior to the exclusive biliary drainage. The first-line exclusive chemotherapy bases on the gemcitabine-cisplatin association with a median survival of 11,6 months. No study allows to justify the administration of a chemotherapy of the second line.

Thus the preservation of the permeability of the biliary ways is today, the most important factor to improve the survival of these patients. Therefore, the addition of a treatment allowing to obtain a local tumoral response to the insertion of biliary prosthesis would allow to increase the duration of permeability of the biliary prosthesis and would limit the local evolution.

Endoductal destruction tumoral technics were thus developed in this indication:

  1. Dynamic phototherapy which demonstrated, during preliminary studies, a certain efficiency both on the tumoral response estimated on the improvement of the tumoral stenosis as on the survival in case of cholangiocarcinoma bile ducts not resectables. However, the improvement of the survival was not confirmed by wider randomized studies. A study randomized of phase III was interrupted prematurely because of a survival decreased in the experimental arm.
  2. The radium therapy and the brachytherapy were estimated in this indication with results interesting on series limited in size, but is not used in routine because of its cost and of technics difficulties.

Ablation therapy technics (radio frequency, microwaves, radium therapy) percutaneous by radiological or surgical way proved their efficiency for the treatment of hepatocarcinoma and liver metastasis.

The hepatic radio frequency was estimated, during trials of phases II, for peripheral cholangiocarcinoma intra hepatic (developed at a distance main bile ducts) with interesting tumoral rates of necrosis.

However, the direct percutaneous access of the cholangiocarcinoma of the biliary ways is not practicable because of the risk of iatrogenic biliary fistula.

Therefore, systems allowing to realize ablation therapy by endoductal radio frequency are from now on available. It is miniaturized bipolar probes which are inserted into bile ducts by reactionary way (retrograde cholangiography), or anterograde percutaneous.

Two systems (Habib ®, ELLRA ®) are at present available and were estimated during in vitro and in vivo studies, to the animal and in man.

The purposes of this study are to estimate the feasibility, the efficiency and the morbidity of the biliary radio frequency for the treatment of the extra hepatic cholangiocarcinoma non resectable (resection or transplantation).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ablation Therapy in people with Nonresectable Bile Duct Cancer, run by Institut Paoli-Calmettes 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 6 inclusion and 7 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 23 Jun 2023. 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.

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?

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?

Rate of success of the use of a treatment based on radiofrequency for all the target stenosis. (time frame: 1 day). 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 23 Jun 2023.
