Official Title  ICMJE Fluorescence QRH-882260 Peptide Imaging in the Bile Duct
Brief Summary Patients undergoing ERCP procedure with biliary stricture will have epithelial mucosa labeled with QRH-882260 fluorescence peptide that binds to EGFR. A custom mini-cholangioscope will be used to image the luminal surfaces of the biliary duct that are exposed to the fluorescence peptide. The images will be recorded and analyzed for relative fluorescence pattern and intensity and correlated to patient diagnosis and clinical outcomes.
Detailed Description

A Phase 1b study of the safety and efficacy of a topically-administered 7-amino acid peptide labeled with a near-infrared fluorophore Cy5 for detecting neoplastic areas of the bile duct is proposed. The study will test the safety and efficacy of administering this agent (QRH-882260 Heptapeptide) to human subjects undergoing clinically indicated ERCP for the evaluation of biliary disorders.

This is a pilot study of a single study group at a single center. The investigators intend to enroll 12 evaluable subjects. Expected enrollment is one subject every 1 month, so the study should take 12 to 24 months to complete. The expected duration of each subject's participation is 2 to 7 days.

Subjects will be recruited around their standard of care procedure. The endoscopists performing study procedures are all credentialed to do these procedures at the UWMC Digestive Health Center.

ERCP will proceed per UWMC standard of care. The endoscopists performing the procedure will evaluate the potential risk (if any) for the subject to continue with the study procedure. Five mL of the reconstituted QRH-882260 Heptapeptide (~100 μM) will be administered to the site of interest through a catheter in the standard endoscope. Five minutes after QRH-882260 Heptapeptide application, the unbound peptide will be washed off using the endogator irrigator and the residual liquid will be suctioned. Pictures with reflection-light and fluorescence will be taken with the SFE based molecular imaging mini-cholangioscope (MC) inserted via the instrument channel of the standard endoscope before the QRH-882260 Heptapeptide application, immediately after application and then again after the QRH-882260 Heptapeptide is rinsed.

The area of interest identified will be biopsied at the discretion of the endoscopist per clinical care. Any specimens taken will be for clinical care only and will be sent for routine histology per UWMC standard of care.
