Brief Summary:
DIGEST I Pilot study is a feasibility study for evaluating the safety and efficacy of DCBs.

Condition or disease Intervention/treatment Phase
Biliary Stricture Biliary Anastomotic Stenosis Biliary Obstruction Biliary Disease Device: GIE Drug Coated Balloon Not Applicable

Detailed Description:

The study is designed to determine the safety and effectiveness of drug coated balloon (DCB) treatments on biliary tract stricture.

Up to 15 subjects are planned to be enrolled and treated with the study device at up to 5 clinical sites outside of US. Subjects will be followed up post-treatment to one year and then annually for up to 5 years. The annual follow up after the first year is optional.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 15 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Drug-Coated Balloon for the Treatment of Symptomatic Chronic Benign Biliary Stricture
Actual Study Start Date : May 12, 2019
Estimated Primary Completion Date : March 21, 2021
Estimated Study Completion Date : March 21, 2025

Arm Intervention/treatment
Experimental: Experimental: DCB Treatment
Stricture patients treated by DCB
Device: GIE Drug Coated Balloon
The GIE DCB is a balloon catheter coated with a proprietary coating containing the drug and carriers.

Primary Outcome Measures :
  1. Incident of serious balloon dilation-related complications [ Time Frame: 30 days ]
    No serious procedure-related complications, including perforation, bleeding requiring invasive intervention or transfusion, cholangitis, pancreatitis, etc.

  2. Freedom from Biliary Stricture Re-intervention [ Time Frame: 12 months ]
    Biliary stricture re-intervention rate

Secondary Outcome Measures :
  1. Change in Liver Function [ Time Frame: 7 days, 30 days, 3 months, 6 months, 12 months and 24 months ]
    . Liver function tests include total and direct bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT)

  2. Change in Existing Biliary Obstructive Symptoms [ Time Frame: 30 days, 3 months, 6 months, 12 months and 24 months ]
    The common biliary obstructive symptoms are right upper quadrant pain (survey), fever/chills (cholangitis), jaundice, itching, dark urine, pale stools, nausea/vomiting, weight loss

  3. Biliary Stricture Diameter [ Time Frame: 6 months ]
    Stricture diameter will be assessed via endoscopic retrograde cholangiopancreatography (ERCP)

  4. Time to the First Re-intervention [ Time Frame: 12 months and 24 months ]
    The mean time to the first re-intervention (scheduled and unscheduled) will be assessed

  5. Sustained Clinical Success (SCS) [ Time Frame: 12 months and 24 months ]
    SCS defined as a period of at least 6 months with no need for further endoscopic intervention

  6. Long Term Clinical Success (LTCS) [ Time Frame: 12 months and 24 months ]
    LTCS, defined as no need for further endoscopic intervention for at least 24 months

  7. Mean number of dilations [ Time Frame: 12 months and 24 months ]
    Mean number of dilations required to achieve SCS and LTCS

  8. Technical Success [ Time Frame: 0 months ]
    Technical success is defined as successful insertion, dilatation of the target biliary stricture, and finally withdrawal of the device with no device malfunctions.
