Chronic pancreatitis is a rare but debilitating condition associated with chronic abdominal pain, diarrhea, diabetes, and an 8-fold increased risk for the development of pancreatic cancer. Unfortunately, there is no available treatment to prevent the progression of chronic pancreatitis, and most subjects require narcotic medications to control the pain. A receptor protein call the CCK-B receptor becomes activated in chronic pancreatitis and is in part responsible for the scar tissue or fibrosis that occurs and responsible for the cancer risk. In mice with chronic pancreatitis, the inflammation and damage was reversed with an old drug called proglumide that blocks the activation of the CCK-B receptor. Proglumide has also been shown to possibly reduce pain.
This protocol involved a 2-Part study to test the safety of oral proglumide in those with confirmed chronic pancreatitis and the second goal is to determine if proglumide improves pain and function of the pancreas. Part-1 is an open-labelled Lead-in Study of N=8 subjects over a 12-week treatment period. Part-2 is a randomized double blind pseudo cross over study where subjects will be treated in Arm A (placebo for 12 weeks followed by 12 weeks of proglumide) and Arm B ( proglumide for 24 weeks).
