Metformin for Abdominal Aortic Aneurysm Growth Inhibition (MAAAGI)
Metformin for AAA Growth Inhibition, a Randomized Controlled Trial
Study Overview

Intervention / Treatment
Detailed Description
Subjects with no history of diabetes will be recruited from a cohort of patients with diagnosed AAA and a maximum aortic diameter of 30-49mm for men and 30-44mm for women.
A total of 500 subjects with AAA will be included in the study, 250 in each study arm. Patients will be randomised to metformin or standard care in a 1:1 ratio.
CT imaging and AAA US will be performed at baseline, 24 months and end of study, as well as if necessary according to clinical routine. Study drug will start at baseline and continue through completion.
When all enrolled subjects have completed the 24-month follow-up (including imaging) an interim analysis will be performed to assess for efficacy and safety; if there is no trend towards a positive effect or signs of a harmful effect of metformin, the study will be stopped at this phase.

- Current or previous use of metformin.
- Not expected to tolerate metformin.
- Contraindications to metformin treatment according to SmPC
- Known or suspected connective tissue disorder (Marfans syndrome, etc), infected or inflammatory aneurysm, aneurysm development after aortic dissection or previous surgery of the infrarenal aorta.
- Enrollment in either another investigational drug or medical device study or another investigational study of an approved drug or medical device within 30 days prior to enrollment of the current study.
- If, in the opinion of the investigator, it is not in the patient's medical interest to participate in the study or the patient is unlikely to be able to comply with the study protocol.

Intervention / Treatment |
---|---|
Experimental: Metformin target dose of 2g daily
Metformin tablets taken orally with target dose of 2g daily plus standard care
