New graft technique offers hope for patients with complex aneurysms

NCT ID NCT01538056

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether specially modified endovascular grafts can safely treat juxtarenal aortic aneurysms—a type of bulge in the main belly artery near the kidney arteries. The grafts are either modified by the doctor or made by a company, and are used in patients who have few other options. The trial aims to enroll 500 adults and will check for safety and success in delivering the graft without leaks or other problems.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Fenestrated endovascular graft (physician-modified or company-manufactured)
What this could lead to
If successful, this could provide a safer, less invasive treatment option for patients with complex aortic aneurysms who have few alternatives.
What could go wrong
This is an early-stage study without a control group, so results may not apply broadly. Risks include major adverse events like endoleaks or graft migration.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 500 people

The number the study aims to enrol. It can still change while the study runs.

Start date

Mar 2011

Expected to finish

Jan 2055

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria: All patients must meet all of the following inclusion criteria to be eligible for enrollment into this study: 1. Patient is \> 18 years of age 2. Patients who are male or non-pregnant female (females of child bearing potential must have a negative pregnancy test prior to enrollment into the study) 3. Patient or Legally Authorized Representative has signed an Institutional Review Board (IRB) approved Informed Consent Form 4. Patient has a juxtarenal abdominal aortic aneurysm that meets at least one of the following: Abdominal aortic aneurysm \>5.5 cm in diameter, Aneurysm has increased in size by 0.5 cm in last 6 months, Maximum diameter of aneurysm exceeds 1.5 times the transverse dimension of an adjacent non-aneurysmal aortic segment 5. Patient has appropriate iliac/femoral artery anatomy for access, with or without the use of a conduit, that will allow endovascular access with the physician modified endovascular graft. 6. Patient has a suitable non-aneurysmal proximal aortic neck length of \> 2 mm inferior to the most distal renal artery ostium. 7. Patient has a suitable non-aneurysmal distal iliac artery length (seal zone) of \>15 mm. The resultant repair should preserve patency in at least one hypogastric artery. 8. Patient has a suitable non-aneurysmal proximal aortic neck diameter between 20 and 32mm, averaged across the diameters at the Celiac, SMA, at the lowest patent renal artery and at the midpoint of the renal arteries. 9. Patient has suitable non-aneurysmal distal common iliac diameters between 8 and 20 mm. 10. Patient has juxtarenal aortic neck angulation \< 60º 11. Patient must be willing to comply with all required follow-up exams Exclusion Criteria: Patients that meet ANY of the following are not eligible for enrollment into the study: 1. Patient has a mycotic aneurysm or has an active systemic infection 2. Patient has unstable angina (defined as angina with a progressive increase in symptoms, new onset at rest or nocturnal angina, or onset of prolonged angina) 3. Patient has a major surgical or interventional procedure planned within +/- 30 days of the AAA repair. 4. Patient has history of connective tissue disease (e.g., Marfan's or Ehler's-Danlos syndrome). 5. Patient has a known hypersensitivity or contraindication to anticoagulation or contrast media that is not amenable to pre-treatment. 6. Patient has a known allergy or intolerance stainless steel or gold 7. Patient has a body habitus that would inhibit X-ray visualization of the aorta 8. Patient has a limited life expectancy of less than 1 year 9. Patient is currently participating in another investigational device or drug clinical trial 10. Patient has other medical, social or psychological conditions that, in the opinion of the investigator, preclude them from receiving the pre-treatment, required treatment, and post-treatment procedures and evaluations. 11. Subject is eligible for enrollment in a manufacturer-sponsored IDE at the investigational site
