Phase 1 In-vivo Biliary Study of KSP/QRH Heptapeptide Dimer

• Status: Recruiting
• Trial end date: 2022-06-01
• Target enrollment: 0
• Participant gender: All

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.

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)

• Subject is medically cleared for the procedure (e.g. washout for anticoagulants, co-morbidities)

• Age 18 to 100 years

• Willing and able to sign informed consent

Exclusion Criteria:

• Subjects with known allergy or negative reaction to any components of the study drug (list these)

• Subjects on active chemotherapy or radiation treatment

• Pregnant or trying to conceive

• Anything that, in the opinion of the investigator, would place the individual at increased risk or preclude the individual's full compliance with or completion of the study
