Brief Summary:
The overall aim of this feasibility study is to develop new technologies for improved detection of cholangiocarcinoma using the SFE-based molecular-imaging mini-cholangioscope (MC) system. This study will combine the use of a fluorescent-labeled peptide dimer that binds specifically to know biomarkers of cholangiocarcinoma for use as a novel imaging agent to guide endoscopic biopsies. This Phase 1B study will be used to provide early evidence of efficacy for the topical application of a peptide dimer that binds to molecular targets that are specific for biliary intra-epithelial neoplasia. A dimer is needed because cancer in the biliary tract is genetically heterogeneous. QRH binds specifically to Epidermal Growth Factor Receptor (EGFR), and KSP binds specifically to Human Epithelial Growth Factor Receptor (HER2). The study will look at peptide binding in subjects having a medical condition requiring an ERCP to diagnose a potential biliary disorder. The Phase 1A first-in-human studies of safety with topical administration by ingestion of KSP/QRH dimer (HUM00141420) has been completed.

Arm Intervention/treatment
Experimental: Dimer Application with SFE imaging
Subjects having a standard-of-care ERCP will have the dimer sprayed on an area of interest in the bile duct and images taken with the SFE.
Drug: KSP/QRH dimer
Peptide 919288G, Lot No. 17081402, Molecular Weight 3577.0, ≥95% purity. Stored at <20°C. Dark green, lyophilized powder in single-use amber vials.




Primary Outcome Measures :
  1. Contrast in Cell Fluorescence [ Time Frame: 2 years ]
    The fluorescence intensity will be measured by the target/background (T/B) ratio from suspicious regions of bile duct where the fluorescent-labeled peptide is administered. The intensity of the fluorescence of the abnormal tissue compared to the background tissue intensity will be analyzed using statistical analysis for significance comparing the tissue groups' mean T/B ratios.

Criteria

Inclusion Criteria:

Subject meets all of the following criteria:

  • Scheduled for an outpatient ERCP to diagnose a potential biliary disorder (such as an indeterminate biliary stricture)
