PCSK9 Inhibition for Abdominal Aortic Aneurysm (AAA)

This study is looking at whether the medication evolocumab can affect the tissue and cells in people with an abdominal aortic aneurysm (AAA). Evolocumab is given by injection and works by lowering "bad" cholesterol (low-density lipoprotein cholesterol or LDL-C). Researchers will compare participants who receive evolocumab to those who receive a placebo (an inactive substance) to see how changes in LDL-C levels impact the aorta's tissue and cells. The main goal is to measure a specific protein called Interleukin (IL)-6 in immune cells from AAA tissue after surgery. You may be able to join if you are over 18, need open surgery for an AAA, and have not used a PCSK9 inhibitor in the last 6 months. The study is currently recruiting 44 participants.

Study design
This is an interventional study where participants are randomly assigned to receive either evolocumab or a placebo. It plans to enroll 44 participants.
What's involved
You will have a baseline visit, receive 3 injections of the study drug or placebo over 5 weeks, and have blood tests and tissue samples taken during your AAA repair. There will also be a follow-up phone call 4 weeks after surgery.
Compensation
Not stated in the trial record.
Follow-up
Participants will have a follow-up phone call 4 weeks after their AAA repair to check for any side effects.

    IL-6 expression will be measured in myeloid cells in the aortic tissue specimens using single nucleus RNA sequencing and confirmed by whole tissue ELISA.
