Trial summary

Currently, very few centers offer Photodynamic therapy for unresectable Cholangiocarcinoma in the United States. Several European studies have reported the efficacy and safety of Photodynamic Therapy (PDT) for Cholangiocarcinoma, however, only a few studies have reported the same in the United States.

About this study

Official title: To Establish a Multicenter Registry to Evaluate the Impact of Photodynamic Therapy in the Management of Patients With Unresectable Cholangiocarcinoma.

Currently, very few centers offer Photodynamic therapy for unresectable Cholangiocarcinoma in the United States. Several European studies have reported the efficacy and safety of Photodynamic Therapy (PDT) for Cholangiocarcinoma, however, only a few studies have reported the same in the United States.

The establishment of a registry to capture all PDT cases within and outside US can help the investigators evaluate a larger and non-ambiguous sample population. This would help the investigators evaluate the technical success rates, clinical success rates, feasibility and safety of PDT for unresectable cholangiocarcinoma. With more endoscopists considering PDT as a therapeutic option along with adjuvant treatment for cholangiocarcinoma, there is a need to further evaluate the efficacy and safety of such combined procedures as well. The ultimate objective is to assess if PDT with or without additional or adjuvant treatment options prolongs survival duration and improves quality of life in patients with unresectable cholangiocarcinoma.

This multicenter registry has been initiated:

  • To document the impact of PDT on the clinical management of unresectable cholangiocarcinoma.
  • To assess the clinical and technical success rates of PDT for unresectable cholangiocarcinoma.
Read the detailed description

PDT offers a number of practical advantages; it is minimally invasive and has a low complication rate, the procedure can easily be performed by a trained endoscopist, and it is well tolerated. In the trial conducted in Germany, the adverse events of PDT were mild to moderate, predictable, and relatively easy to control. Photosensitivity was the only systemic side effect (seen in only three patients). However, provided that simple guidelines for light exposure are followed, there is minimal risk to the patient, as shown by the low incidence of photosensitivity reactions in this study which all resolved.

A study from the Mayo group included 25 patients with unresectable cholangiocarcinoma who were treated with PDT from 1991 to 2004 showed that the time interval between diagnosis and treatment with PDT is an important predictor of survival following PDT even when adjusted for other potential factors that affect survival such as age, gender, Bismuth stage, presence of tumor mass on imaging and presence of extra biliary spread. Early treatment with PDT may lead to greater preservation of liver function. A recent study by the primary investigator has also recently reported improved survival in patients receiving PDT and stent compared to stent only (16.2 months vs 7.4 months).

Several other European studies have reported the efficacy and safety of PDT for cholangiocarcinoma; however, only a few studies have reported the same in the United States. This is again due to the fact that PDT is not offered as a therapeutic option for unresectable cholangiocarcinoma within US.

However, the establishment of a registry to capture all PDT cases within and outside US can help the investigators evaluate a larger and non ambiguous sample population. This would help the investigators evaluate the technical success rates, clinical success rates, feasibility and safety of PDT for unresectable cholangiocarcinoma.

The involvement of international sites is crucial, as the advanced endoscopists all over the world are offering photodynamic therapy for managing unresectable cholangiocarcinoma. However, because of the non-existence of a registry, and the fact that PDT is not offered in more than a few centers in the US; these cases are often reported with a smaller sample size. The registry hopes to combine all such comparable cases and collect enough relevant data for statistical analyses.

With more endoscopists considering PDT as a therapeutic option along with adjuvant treatment for cholangiocarcinoma, there is a need to further evaluate the efficacy and safety of such combined procedures as well. The ultimate objective is to assess if PDT with or without additional or adjuvant treatment options prolongs survival duration and improves quality of life in patients with unresectable cholangiocarcinoma.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Photodynamic TherapyProcedure or surgery

    Also called PDT

    PDT is a therapeutic approach that specifically targets neoplastic cells.

    • PDT involves three components:
    1. Photofrin or a similar Photosensitizing agent that would be injected 3 days prior to laser activation of the agent.
    2. Laser System - For laser energy delivery to activate the photosensitizing agent and induce tumor tissue necrosis
    3. Optic Fiber - Delivery Fiber used along with the laser system to achieve Photoactivation of the photosensitizing agent.

    Technique:

    Subjects will be injected with Photofrin or similar drug. 3 days post injection, the subject will receive photodynamic therapy during an Endoscopic Retrograde cholangiopancreatography (ERCP) procedure. Subject will undergo stenting as part of standard of care procedure post photodynamic therapy.

    Subject may undergo multiple photodynamic therapy sessions with a gap of at least 3 months.

What is being measured

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

Questions about this trial

What is this clinical trial studying?

An observational study of Unresectable Cholangiocarcinoma and Biliary Obstruction, run by Weill Medical College of Cornell University at 2 sites 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 2 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 20 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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.

How can a doctor refer a patient or contact the research team?

Contact Michel Kahaleh, M.D. (646-962-4797, mkahaleh@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety (time frame: 3 years). It is what the study was designed to measure, not a finding.
