Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Radiographically (CT or EUS) distal malignant bile duct obstruction
  • Histology or cytology proven malignancy of the primary tumour or metastasis; onsite cytology evaluation after EUS guided fine-needle sampling that is highly suspected of a malignancy suffices
  • Indication for biliary drainage; in case of a resectable tumour this should be discussed during a clinical multidisciplinary meeting
  • Written informed consent

Exclusion Criteria:

  • Age < 18 year
  • Surgically altered anatomy after previous gastric, periampullary or duodenal resection
  • Cancer extending into the antrum or proximal duodenum
  • Extensive liver metastases
  • WHO performance score of 4 (in bed 100% of time)
  • Uncorrectable coagulopathy, defined by INR>1.5 or platelets < 50 x 10^9/L*
  • Clinically relevant gastric-outlet obstruction

  • Unable to complete sign informed consent

    • Inclusion is allowed after corrective treatment measures are taken, according to local protocol and treating physician.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Stentdysfunction after technical successful EUS-CDS
Time Frame: 6 months
Recurrent jaundice after initial clinical success, ongoing jaundice in combination with remaining dilatation of the bile ducts, or cholangitis.
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of participants with technical success of LAMS placement
Time Frame: 1 day (directly after intervention)
Successful creation of a choledochoduodenostomy using a LAMS
1 day (directly after intervention)
Number of participants with technical success of FCSEMS through LAMS
Time Frame: 1 day (directly after intervention)
Successful placement of FCSEMS through LAMS.
1 day (directly after intervention)
Number of participants with clinical success
Time Frame: 14 days
50% decrease or normalization of bilirubin level within 14 days of the procedure. Presumed persistant hepatic secretory failure with ongoing jaundice but decreased diameter of the bile ducts and decrease of ALT, alkaline phosphatase and gamma-glutamyl transpeptidase is not considered clinical failure of the intervention.
14 days
Procedure time
Time Frame: 1 day (directly after intervention)
Is measured from introduction of endoscope in the patient until removal of endoscope after completion of the procedure. In case a fine needle aspiration (FNA) or biopsy (FNB) needs to be taken from the primary tumour to confirm malignancy, time is measured after completion of this procedure.
1 day (directly after intervention)
Adverse events
Time Frame: 6 months
Are defined as any probably or definitely procedure- or admission related adverse event occurring after EUS-CDS. Severity will be recorded and graded NL81840.029.22 version 1.1 08-08-2022 SCORPION-II-pilot study 23 of 45 (mild, moderate, severe or fatal) according to the ASGE lexicon.(23) Common or expected AEs are defined according to the ASGE lexicon (including the following categories: cardiovascular, pulmonary, thromboembolic, perforation, bleeding, infection, pain).
6 months
Time to stent dysfunction
Time Frame: 6 months
Is calculated from the moment of stent insertion until stent dysfunction for which a new procedure is required.
6 months
Number of re-interventions
Time Frame: 6 months
Is defined as any unplanned intervention (endoscopic, intervention radiology or surgical) for an adverse event, persistent jaundice or recurrent obstructive symptoms, that is needed after EUS-CDS.
6 months
Time to start treatment (chemotherapy or surgery)
Time Frame: 6 months
Is defined as the number of days after EUS-CDS until initiation of chemotherapy or surgery.
6 months
Hospitalization
Time Frame: 30 days
Is defined as the number of days patient was admitted within the first 30 days after the procedure.
30 days
Survival
Time Frame: 6 months
Is defined by the number of days after EUS-CDS until death. The cause of death will be registered
6 months
Costs
Time Frame: 6 months
Are defined as the intramural costs that were involved with EUS-CDS, collected from the electronic hospital records and linked to the Dutch unit costs
