Trial summary

The study aim to evaluate the efficacy of intraductal radiofrequency ablation for unresetable hilar cholangiocarcinoma in addition to biliary stenting. The patient would be randomized into 1:1 ratio of conventional group who received biliary stenting alone, and RFA group who receive intraductal RFA before biliary… Read more about this study

About this study

The study aim to evaluate the efficacy of intraductal radiofrequency ablation for unresetable hilar cholangiocarcinoma in addition to biliary stenting. The patient would be randomized into 1:1 ratio of conventional group who received biliary stenting alone, and RFA group who receive intraductal RFA before biliary stenting. Immediate complications as well as long term stent patency and patient survival would be studied.

Read the detailed description

Study design: randomized single-blind control trial Study population: patient with unresectable hilar cholangiocarcinoma with obstructive jaundice who need hilar biliary stenting Primary endpoint: Biliary stent patency time Secondary endpoint: Patient survival Intervention

  1. Recruited patients randomly assigned into 2 groups, conventional and RFA group by sealed enveloped
  2. All patients receive endoscopic biliary stenting. Those in RFA group receive RFA before biliary stent.
  3. Monitor for adverse event during hospitalization and during follow up
  4. Follow up as outpatient in 4-weekly interval with monitoring of serum liver function test as routine
Being tested
ELRA endoluminal radiofrequency ablation electrode (Taewoong, Seoul, Korea)

ConventionalNo interventionPatient receive endoscopic placement of metallic biliary stent for obstructive jaundice
Radiofrequency ablationExperimentalPatient receive endoscopic intraductal radiofrequency ablation before placement of biliary stent for obstructive jaundice
Receives: Device: ELRA endoluminal radiofrequency ablation electrode (Taewoong, Seoul, Korea)

What is being measured

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

  1. Biliary stent patency

    The duration between primary intervention and first recurrent increased in serum total bilirubin after intervention up to 6 months after the primary procedure

    Measured: up to 6 months

Secondary outcomes (1)
  1. Patient survival

    Survival time after primary intervention and documented patient death at 6 months after primary intervention

    Measured: up to 6 months

Questions about this trial

What is this clinical trial studying?

A study testing ELRA endoluminal radiofrequency ablation electrode (Taewoong, Seoul, Korea) in people with Hilar Cholangiocarcinoma and Biliary Obstruction, run by Department of Medical Services Ministry of Public Health of Thailand at 1 site in Thailand.

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 3 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 23 Mar 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 Thailand. 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?

Biliary stent patency (time frame: up to 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04611100, which also lists 5 linked publications.

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 Mar 2022.
