About this study

Official title: Phase 1 In-vivo Study of KSP/QRH Heptapeptide Dimer for Detection of Biliary Intra-epithelial Neoplasia

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • KSP/QRH dimerDrug

    Peptide 919288G, Lot No. 17081402, Molecular Weight 3577.0, ≥95% purity. Stored at <20°C. Dark green, lyophilized powder in single-use amber vials.

Study groups in NCT04304781
Study groupRoleWhat they receive
Dimer Application with SFE imagingExperimentalSubjects 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.
Receives: Drug: KSP/QRH dimer

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Contrast in Cell Fluorescence

    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.

    Measured: During and immediately after procedure, generally no more than 2 hours

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing KSP/QRH dimer in people with Cholangiocarcinoma, run by Danielle Kim Turgeon at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 22 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Terminated due to lack of dimer.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Contrast in Cell Fluorescence (time frame: During and immediately after procedure, generally no more than 2 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Nov 2022.
