Pre-operative Biliary SEMS RCT During Neoadjuvant Therapy

Not Applicable
Completed
Conditions
Pancreatic Cancer
Interventions
Device: WallFlex™ Biliary RX Fully Covered/Uncovered Stent System
Registration Number
NCT02238847
Lead Sponsor
Boston Scientific Corporation
Brief Summary

The purpose of this study is to demonstrate non-inferiority of Fully Covered biliary SEMS to Uncovered biliary SEMS in biliary drainage for the pre-operative management of biliary obstructive symptoms caused by pancreatic cancer in patients undergoing neoadjuvant therapy.

119
Inclusion Criteria
  • Age 18 or older
  • Patient indicated for biliary metal stent placement for the treatment of jaundice and/or cholestasis

Primary Outcome Measures
NameTimeMethod
Sustained Biliary Drainage, Defined as Absence of Reinterventions for the Management of Biliary Obstructive SymptomsFrom SEMS placement until CIS (for patients undergoing CIS; median 110 days to CIS) or from SEMS placement to one year after SEMS placement (for patients not undergoing CIS)

Sustained biliary drainage, defined as absence of reinterventions for the management of biliary obstructive symptoms, assessed from self-expanding metal stent (SEMS) placement until curative intent surgery (CIS) when applicable, or to one year after SEMS placement otherwise.

Secondary Outcome Measures
NameTimeMethod
Procedure-related or Stent-related Serious Adverse EventsFrom stent placement procedure up to one year after stent placement procedure

Serious adverse events related to the stent placement procedure or to the stent

Technical SuccessDuring the Stent Placement Procedure

Technical success defined as the ability to deploy the stent in a satisfactory position across the stricture; proximal end of the stent is no more than 1-2cm beyond the proximal end of the stricture.

Ability to Complete Neoadjuvant Therapy as Intended Without Stent-related Interruptions of Neoadjuvant Therapy and Without Biliary ReinterventionFrom initial stent placement procedure to curative intent surgery (CIS) (median 110 days to CIS), or from initial stent placement procedure to one year after initial stent placement for participants not undergoing CIS

The ability to complete neoadjuvant therapy as intended without stent-related interruptions of neoadjuvant therapy and without biliary reintervention

Number of Participants With Stent MigrationAt the time of curative intent surgery (CIS) (median 110 days to CIS) or transition to palliation for participants not underoing CIS

The number of participants with stent migration

Subjective Impression of the Surgeon That the Presence of a Self-expanding Metal Stent May Have Impacted the Surgical ProcedureAt the time of curative intent surgery (CIS) (median 110 days to CIS)

The subjective impression of the surgeon that the presence of a self-expanding metal stent (SEMS) may have impacted the surgical procedure.

For Participants Not Undergoing Curative Intent Surgery, Sustained Biliary Drainage to One Year After Stent PlacementFrom stent placement to one year after stent placement for participants not undergoing curative intent surgery

For participants not undergoing curative intent surgery, sustained biliary drainage from stent placement to one year after stent placement.
