About this study
Official title: Pilot Study to Assess Safety and Efficacy Of An Endoscopic Bipolar Radiofrequency Probe (EndoHPB) In the Management of Unresectable Bile Duct and Pancreatic Cancer
The purpose of this study is to determine whether the use of an FDA approved endoscopic bipolar catheter (EndoHPB) will ablate tissue in malignant tumors within the pancreatic ducts.
Read the detailed description
Only a small proportion of patients with biliary obstruction caused by cholangiocarcinoma or pancreatic cancer are suitable for surgical resection. Therefore most patients with malignant biliary obstruction will need palliation of their jaundice to relieve the symptoms of pruritus, malabsorption, sepsis and to minimize potential hepatorenal complications. Restoring biliary flow with relief of jaundice is the primary goal in the palliation of obstructive biliary malignancy. Drainage at endoscopic retrograde cholangiopancreatography (ECRP) is established as a safer approach than at percutaneous transhepatic cholangiography (PTC) because it has a lower risk of bile leak, infection and hemorrhage. ECRP is the first approach to relieve malignant biliary obstruction but sometimes it is not technically possible to stent the patient by this approach, then a PTC needs to be undertaken. Self expanding mesh metal stents (SEMS) were introduced back in the 1990s. Problems can still arise with the use of covered stents such as cholecystitis, pancreatitis or tumor overgrowth at the end of the stent, and not all studies have shown that covered stents actually reduce the problems of tumor ingrowth and consequent stent occlusion. EndoHPB can be deployed via an ERCP or PTC route. By using radiofrequency (RF) energy to heat the tissue in the duct prior to insertion of the stent, the surrounding tissue becomes coagulated and this may may delay tumor growth and the time before the stent lumen becomes blocked. Thereby this allows increased periods between the need for intervention and further stent deployment. If EndoHPB use of luminal RF is demonstrated to be effective in luminal tumor ablation, it may have an additional role as a form of neoadjuvant therapy in cholangiocarcinoma and pancreatic cancer.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Endoscopic Bipolar RadioFrequency Probe used to remove tumors in bile duct to manage Pancreatic Cancer in people with Pancreatic Cancer, run by Ochsner Health System.
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 5 inclusion and 6 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 23 Jan 2014. Status can change between updates, so confirm with the study contact before making plans.
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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
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?
Improvement in size(patency of bile duct) measured by cholangiography or cholangioscopy, immediately post ablation (time frame: Baseline through visit 7). 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 Jan 2014.
