Study population: Patients diagnosed with PSC

Who may be able to join

  • Confirmed diagnosis of PSC
  • Clinical indication for ERCP per local standard of practice, such as suspicion of potential malignancy based on worsening cholestatic values or clinical presentation (such as itching, cholangitis) or new biliary stricture on trans-abdominal imaging (MRI/MRCP, US or CT) or suspicious cytology

What participants receive

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

  • SpyGlass DS I - IIDevice

    The SpyScope™ DS Access and Delivery Catheter (SpyScope™ DS Catheter) is a sterile, single-use endoscope that enables access and delivery of accessories to targeted pancreaticobiliary anatomy and displays live video when connected to a Spy Glass DS Digital Controller.

Study groups in NCT03766035
Study groupRoleWhat they receive
Consented, enrolled PSC patients undergoing ERCP + SpyGlassPatients with PSC who have been consented and enrolled in the study will undergo ERCP with the addition of SpyGlass as indicated by their treating physician.
Receives: Device: SpyGlass DS I - II

What is being measured

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

  1. Diagnostic Accuracy of POCS visualization for Early Detection of Cholangiocarcinoma

    Diagnostic accuracy of POCS visualization for cholangiocarcinoma evaluated clinically at 12 months after initial POCS procedure by clinical presentation.

    Measured: 12 months

  2. POCS-guided Biopsy for Early Detection of Cholangiocarcinoma

    Diagnostic accuracy for POCS-guided Biopsy for cholangiocarcinoma evaluated on pathology at 12 months after initial POCS procedure.

    Measured: 12 months

Secondary outcomes (4)
  1. Technical Success - Ability to advance the scope.

    Ability to advance the cholangioscope to the target stricture, ability to visualize the stricture and ability to obtain a tissue sample with Spy Bite where applicable.

    Measured: Baseline

  2. Rate of Adverse Events

    Serious adverse events from initial POCS procedure until end of follow-up.

    Measured: From index through study completion, an average of one year

  3. Proportion of patients identified for repeat procedure.

    Proportion of patients identified for repeat procedure considering the addition of Spy Glass DS visualization and Spy Bite biopsy at Index compared to the proportion identified for repeat procedure without consideration of Spy Glass DS visualization and Spy Bite biopsy at Index.

    Measured: During index procedure

  4. Correspondence of Biopsies

    Correlation between histopathology of Spy Bite biopsies collected during the initial POCS procedure and final diagnosis.

    Measured: From index through study completion, an average of one year

Questions about this trial

What is this clinical trial studying?

An observational study of Primary Sclerosing Cholangitis (PSC), run by Boston Scientific Corporation at 6 sites in 4 countries.

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 4 inclusion and 7 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: finished, as of the sponsor's last update on 25 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States, Canada, Netherlands, Norway. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Diagnostic Accuracy of POCS visualization for Early Detection of Cholangiocarcinoma (time frame: 12 months). The study lists 2 primary outcomes in all. 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 25 Jan 2023.
