Using alpha-ketoglutarate to improve outcomes in patients with abdominal aortic aneurysms
Official title: The Intervention Effect Of Alpha-Ketoglutarate On Abdominal Aortic Aneurysm Progression and Rupture: A Prospective, Randomized Parallel Controlled Study Based On Large Cohorts
Run by RenJi Hospital · NCT04723888 · Data updated 2026-11-12
This study is testing if a nutritional supplement called alpha-ketoglutarate can help people with abdominal aortic aneurysms feel better and reduce the risk of their condition getting worse.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are Han nationality individuals aged 50 and older with an infrarenal AAA of 39-49 mm in diameter.
✕Probably not a fit
Patients with previous aortic surgery, known aortic dissection, or severe infections may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This project aims to determine if the nutritional supplement alpha-ketoglutarate can enhance outcomes for patients with abdominal aortic aneurysms (AAAs) measuring 39-49 mm in diameter. The study will involve oral administration of the supplement, which is known for its role in energy metabolism and is commonly used by athletes. Participants will be monitored for up to five years to assess the impact on AAA progression and rupture risk. The research seeks to establish a prediction model for AAA rupture risk in an elderly cohort.
Why it matters
Potential benefit: If successful, this approach could provide a novel method to slow the progression of abdominal aortic aneurysms and reduce the risk of rupture.
How similar studies have gone: While the use of alpha-ketoglutarate in this context is novel, its application in other metabolic and aging-related studies has shown promising results.
