Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Interventional

Arm Description

Use of the EAST System for the stabilization treatment of AAA. The device is delivered endovascularly and placed in the AAA sac to deliver the Stabilizer Infusion Solution.

Outcomes

Primary Outcome Measures

Safety: Procedure and Device-Related Adverse Events
Absence of major events (procedure and device-related) within the 1-month follow-up visit
Efficacy: Successful delivery of the EAST System into the AAA sac
Successful insertion of the delivery catheter and delivery of the Stabilizer Compound

Secondary Outcome Measures

Efficacy: Evaluation of the AAA sac diameter over the 36 month follow up period.
Freedom from aneurysmal sac enlargement. Enlargement is defined as diameter increase of >5mm per year, or aneurysm sac volume increase of >10% per year, as assessed by CT scans at the 1, 3, (HK only), 6, 12, 24 and 36-month follow-up visits.
Efficacy: Evaluation of the AAA sac shrinkage over the 36 month follow up period.
Aneurysm sac shrinkage, defined as diameter decrease of >5mm, or decrease in aneurysm sac volume of >10% as assessed by CT scans at the 1, 3 (HK only), 6, 12, 24 and 36-month follow-up visits.

5. Study Description

Brief Summary
This is a first in human study to evaluate the safety and clinical utility of an investigational medical device called the Nectero EAST System to treat Abdominal Aortic Aneurysms or AAA.
Detailed Description
This is a Phase I multi-center, open-label study to evaluate use of the Nectero EAST system for stabilization of abdominal aortic aneurysms. Up to fifty (50) subjects will be treated at up to 10 worldwide sites with the device and followed for up to 36-months. Primary Study Endpoints: Safety: absence of major events within the 1-month follow-up visit Success: defined as successful insertion of the delivery catheter and delivery of the Stabilizer Secondary Study Endpoints: Freedom from aneurysmal sac enlargement. Enlargement is defined as diameter increase of >5mm per year, or aneurysm sac volume increase of >10% per year, as assessed by CT scans at the 1, 3, (HK only), 6, 12, 24 and 36-month follow-up visits. Aneurysm sac shrinkage, defined as diameter decrease of >5mm, or decrease in aneurysm sac volume of >10% as assessed by CT scans at the 1, 3 (HK only), 6, 12, 24 and 36-month follow-up visits. Assessment of Clinical Utility Study duration is anticipated to be 6 years.

Arm Title
Interventional
Arm Type
Experimental
Arm Description
Use of the EAST System for the stabilization treatment of AAA. The device is delivered endovascularly and placed in the AAA sac to deliver the Stabilizer Infusion Solution.
Intervention Type
Device
Intervention Name(s)
Endovascular Aneurysm Stabilization Treatment (EAST)
Intervention Description
Endovascular procedure: an ipsilateral ilio-femoral aortogram to confirm suitability for placement of a 14F sheath will be performed. A baseline contrast aortogram will be performed to assess vessel patency and target location of the EAST delivery catheter. Occluding and Stabilizer balloons are inflated in preparation for Stabilizer Compound delivery within the AAA sac. A post-Stabilizer angiogram will re-assess vessel patency and aorta stability. Delivery catheter is removed and discarded. The entire procedure is approximately one hour.
