About this study

Official title: Comparison of Biliary Stenting Alone vs. Stenting With Photodynamic Therapy During Endoscopic Retrograde Cholangiopancreatography (ERCP): A Retrospective and Prospective Analysis

This study entails retrospective and prospective review of data from a database protocol. Data gathered will be then analyzed for a set amount of patients. In this study, the investigators will compare biliary stenting vs. biliary stenting plus photodynamic therapy (PDT) and assess if PDT can improve quality of life and prolong survival.

Read the detailed description

Successful palliation of biliary obstruction is the main goal for reducing morbidity and mortality in patients with biliary disease and biliary obstruction related to cholangiocarcinoma. Surgical biliary bypass is unfortunately complicated by a 30-day postoperative mortality rate of between 7 and 24%. Moreover, because of recovery time the quality of life following surgery is only improved in a minority. At present endoscopic insertion of a plastic or metal stent is the method of choice to relieve obstructive jaundice without the high morbidity and mortality associated with surgery. But this relief is unfortunately temporary since stents tend to become obstructed and the fact that effective biliary drainage in the proximal lesion is challenging. Photodynamic Therapy (PDT) is a new therapeutic approach that specifically targets neoplastic cells. This therapy involves the intravenous administration of a photosensitizing agent followed by activation of the agent by illumination with non-thermal light of a specific wavelength, resulting in cell death from direct cytotoxicity and ischemic necrosis. Cytotoxicity is directly proportional to tissue oxygenation.

A prospective, randomized and controlled trial study by Ortner et all confirmed the significant advantage of PDT with regard to relief of jaundice, quality of life, and survival. The improvement of survival in the randomized PDT group was so impressive that it was believed unethical to continue with randomization after the first 39 patients (20 and 19 in each group).Previously, the principal investigator conducted such a study (and also conducted Endoscopic Retrograde Cholangiopancreatography with PDT) at the University of Virginia, and would continue to conduct these procedures, as well as the study at WCMC.

What is being measured

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

  1. Number of days patients survived post treatment

    The group that receives PDT plus stenting will be compared to the group that received stenting only and their survival duration would be evaluated.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Cholangiocarcinoma, run by Weill Medical College of Cornell University 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 3 inclusion and 3 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: withdrawn, as of the sponsor's last update on 3 Jun 2015. 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.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Number of days patients survived post treatment (time frame: 2 years). 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 NCT01439685, which also lists 2 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 3 Jun 2015.
