Clinical Trial Summary

POISE I study is a feasibility study for evaluating the safety and efficacy of DCB.

Description:

The study is designed to determine the safety and effectiveness for drug coated balloon (DCB) for treating intestinal strictures. 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.

Eligibility

Inclusion Criteria:

1. Age = 18 and = 80 years.

2. Contraindication to endoscopy, anesthesia or deep sedation.

3. Malignant bowel stricture.

4. Extrinsic benign bowel stricture due to adhesion.

5. Stricture complicated with abscess, fistula, ulceration or associated with mesenteric vessel thrombosis

6. More than 2 stenosis/stricture lesions.

7. Length of stenosis/stricture > 7 cm.

8. Stricture not accessible by endoscopy.

9. Suspected perforation of the gastrointestinal tract

10. Acute bowel obstruction requiring urgent surgical intervention

11. Low rectal or anal strictures

12. Severe coagulation disorders (platelets < 70000; INR > 1.8).

13. Active systemic infection

14. Allergy to paclitaxel or any components of the delivery system.

15. Life expectancy of less than 12 months.

16. Drug abuse or on chronic steroid therapy for comorbidities.

17. Unwilling or unable to comply with the follow-up study requirements.

18. Lacking capacity to provide informed consent.

19. Concurrent medical condition that would affect the investigator's ability to evaluate the patient's condition or could compromise patient safety.

20. Currently participation in another pre-market drug or medical device clinical study.

21. Chronic steroid use for any medical conditions unless subject is willing to undergo a 4-week washout and discontinue steroid use.

22. Currently requiring abdominal radiation therapy

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incident of serious balloon dilation-related complications	Perforation, bleeding requiring endoscopic or surgical interventions or blood transfusion, severe abdominal pain requiring medications, infection requiring hospitalization or IV antibiotics	30 days
Secondary	Procedure success	defined as subjects who were treated with GIE DCB achieved at least one scale improvement of the Endoscopic Obstructive Scale (EOS).	6 months
Secondary	Percent subjects with improvement in Endoscopic Obstructive Scale (EOS)	Analyzed by 1, 2, or 3 scale improvement.	6 months
Secondary	Change in obstructive symptoms using the Obstructive Symptom Score (OSS).	The Obstructive Symptom Score (OSS) is a composite measure of the total number of days of obstructive abdominal pain and the severity over a fourteen-day period using a 5-point Likert scale. (1=no pain, 2=mild, 3=moderate, 4=severe, 5=unbearable).	30 days, 3 months, 6 months, and 12 months
Secondary	Number of repeated stricture dilation procedures	Repeat dilation for stricture recurrence	30 days, 3 months, 6 months, and 12 months
Secondary	Procedural technical success	Successful endoscopic passage followed by successful delivery of the drug-coated balloon to the stricture area without resistance, inflated balloon to the defined diameter, DCB withdraw after deflating balloon without device malfunction.	Time of procedure
