1. To assess the effect of RG1068 at a dose of 0.2 mcg/kg intravenously (IV) on the diameter of the pancreatic duct when used during Multidetector Computed Tomography (MDCT) of the pancreas. 2. To demonstrate that RG1068-enhanced MDCT improves image quality of the pancreas in patients with chronic pancreatitis. 3. To evaluate if RG1068 enhanced MDCT results in improved delineation of structural abnormalities of the pancreatic duct as compared to non-enhanced MDCT.

Study summary:

Multidetector Computed Tomography (MDCT) is the mainstay of imaging for patients with acute or chronic pancreatitis, suspected pancreatic neoplasms and post-pancreatic surgery evaluation. The use of multidetector row helical CT scanners and sub-second gantry rotations, have dramatically reduced scan acquisition time with resultant improvement in patient compliance and image quality. The improved Z-axis (isotropic) resolution permits excellent image reconstructions, which play a critical role in diagnosis and staging of pancreatic pathologies, due to the anatomic layout of the pancreas and its vasculature. Fast scanning time enables the acquisition of multiple phases of enhancement, which is of paramount importance in imaging the pancreas [1]. Until relatively recently, endoscopic retrograde cholangiopancreatography (ERCP) was the primary diagnostic and therapeutic modality for assessing patients with suspected pancreatic disease or abnormalities. However, this invasive procedure carries with it a significant potential for complications including acute pancreatitis, hemorrhage and infection, as well as reactions to contrast material or premedications and exposure to radiation. In addition, the success of such procedures - both from the standpoint of safety and efficacy - is highly dependent on the skill of the endoscopist [2], and the cost of ERCP is relatively high. Secretin enhanced MRCP (S-MRCP) has been extensively used in assessment of suspected pancreatic diseases. Likewise, administration of secretin intravenously to patients undergoing MDCT for the pancreas will result in improved distension of the pancreatic duct. The potential benefits of this would be a non-invasive evaluation of the pancreatic duct morphology. In patients with suspected abnormality involving the main duct or its side branches, the improved distension of the duct is likely to improve diagnostic yield for conditions such as intraductal papillary mucinous neoplasms (IPMNs) and cystic pancreatic neoplasms. This study is being undertaken to prospectively assess the effectiveness of RG1068-enhanced MDCT relative to unenhanced MDCT. RG1068 is a synthetic human secretin with a pharmacological profile very similar to that of biological and synthetic porcine secretins. Secretin is a 27-amino acid gastrointestinal peptide hormone that is produced by S-cells in the duodenum in response to the pH decrease caused by the passage of partially digested food from the stomach into the intestine. RG1068 is identical in amino acid sequence to naturally occurring human secretin and differs from porcine secretin in 2 amino acids.
