What this trial studies

This study investigates how Sirolimus, a medication known for its immunosuppressive properties, affects the molecular changes associated with cerebral aneurysms. Participants will undergo either microsurgical clipping or endovascular treatment for unruptured cerebral aneurysms while receiving Sirolimus. The goal is to understand the drug's impact on the underlying biology of these aneurysms, potentially leading to improved treatment strategies. The study is being conducted at Jackson Memorial Hospital in Miami, Florida.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are scheduled for treatment of unruptured cerebral aneurysms at Jackson Memorial Hospital.

Not a fit: Patients with dissecting, traumatic, or mycotic aneurysms, or those with significant comorbidities or contraindications to Sirolimus will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new therapeutic approaches for managing cerebral aneurysms.

How similar studies have performed: While the use of Sirolimus in this context is novel, similar studies exploring molecular treatments for aneurysms have shown promise.
