A Proof-of-Concept Study Evaluating LINFU™

Pancreas Adenocarcinoma Clinical Trial

Official title: A Proof-of-Concept Study Evaluating LINFU™: A Noninvasive Method for Increasing Exfoliation of Pancreatic Ductal Cells Into the Pancreatic Fluid for the Early Detection of Pancreatic Ductal Adenocarcinoma (PDAC)

Status Completed

Clinical Trial Summary

The purpose of this research study is to study a method to detect pancreatic precancer and cancer (ductal adenocarcinoma) using ultrasound technology in those who are at significantly increased risk for developing pancreatic cancer. The LINFU™ Technique is done by analysis of pancreatic fluid collected with the help of ultrasound. This is an investigational way to detect pancreatic precancers and ductal adenocarcinoma.

Clinical Trial Description

Patients will undergo collection of pancreatic fluid by the LINFU™ Technique as part of this study. This procedure takes about 30-45 minutes. The details for the procedure are listed below. LINFU™ Technique 1. Once the participant is sedated or under anesthesia, low intensity non-focused ultrasound excitation of the pancreas will be implemented. This means the sound waves from the ultrasound on the top of the stomach will be used to stimulate the pancreas to release juice. 2. During the ultrasound, the Investigator will administer Lumason through a vein in the participant's arm (IV). Lumason is a contrast agent that was frequently used to create bubbles that allows a better visualization of images. In this study, Lumason will be used to create bubbles and possibly increase the number of pancreatic cells collected for the study. 3. After 25 minutes of ultrasound, the participant will receive an IV dose of secretin over 1 minute. Naturally, secretin is a hormone released into the bloodstream by a part of the small intestine, namely duodenum, (especially in response to acidity) to stimulate secretion by the liver and pancreas. In this study, Secretin is used to increase the number of pancreatic cell excretion to maximize the number of cells collected. 4. The participant will then undergo EGD (insertion of a tube down the throat and past the stomach). EGD stands for esophagogastroduodenoscopy. The Investigator who is doing EGD will discuss all risks and explain how the procedure will be done. 5. The pancreatic juice will be collected immediately. About 15 minutes after the EGD procedure has begun, a second dose of secretin will be administered. 6. The pancreatic juice will continue to be collected for a total of 30 minutes. The results of the LINFU technique will be provided to the investigator to help guide medical care. This is an experimental technique so participants won't receive the results. Participants will undergo clinical diagnostic procedures including EUS (endoscopic ultrasound) and/or MRI as part of the standard medical care and evaluation for pancreatic cancer. These procedures are not part of the study and the Investigator has already determined that these tests are required. Participants will be called 24 hours after the study procedure and 30 days after the procedure to see if any symptoms of pancreatitis (inflammation of the pancreas have developed). If so, participants will be asked to come back to the clinic for further evaluation as would be done as part of the standard medical care. In addition, participants will have blood tests before the LINFU procedure and this will be repeated 24hours after the procedure. The blood tests will measure lipase levels to make sure there was no injury to the pancreas. Any identifiable private information or specimens collected and/or used for the purposes of this research will not be used or distributed for future research studies. ;
