ClinConnect Summary

The Citadel Embolization Device Study is a clinical trial that aims to learn more about the safety and effectiveness of a new treatment device called the Citadel Embolization Device, which is designed to help with a specific type of brain aneurysm known as wide-neck intracranial aneurysms. This type of aneurysm is a bulge in a blood vessel in the brain that has a wider neck and can be more challenging to treat. The study is currently looking for participants aged between 18 and 80 who have a single, unruptured or recently ruptured aneurysm that meets certain size and shape criteria. To qualify, participants must also be in stable neurological condition and willing to follow study procedures.

If you join this trial, you’ll receive treatment with the Citadel device alongside standard coils used for aneurysm treatment. Throughout the study, you’ll have regular follow-up appointments to monitor your health and the effectiveness of the treatment. This trial is important as it could provide valuable information that may improve treatment options for people with wide-neck brain aneurysms. If you or a loved one is considering participation, it's essential to speak with your healthcare provider to understand more about the study and whether it’s the right choice for you.

Eligibility criteria

• Inclusion Criteria:
• • 1. Age is ≥18 and ≤80 years
• • 2. Has a single, unruptured or ruptured target intracranial aneurysm that is suitable for endovascular treatment. Definition: For the purposes of this study, a ruptured intracranial aneurysm is defined as one with CT/MRI/LP evidence of subarachnoid hemorrhage attributed to the index aneurysm within the last 60 days.
• • 3. Aneurysm morphology is saccular
• • 4. Aneurysm size is between 6-12 mm
• • 5. Has a wide-neck, saccular aneurysm, either bifurcation or sidewall, with a dome to neck ratio \<2 or neck ≥4 mm
• • 6. If the target intracranial aneurysm is classified as ruptured, patient must be neurologically stable with a Hunt \& Hess Score of 1 or 2.
• • 7. Must be willing to comply with protocol required procedures and follow up
• • 8. Subject or LAR must be willing to sign and date an IRB approved written informed consent prior to initiation of any screening or study procedures
• Exclusion Criteria:
• • 1. Target aneurysm has been previously treated
• • 2. Target aneurysm is in any extradural location, including the extradural cavernous segment
• • 3. Has vessel characteristics, tortuosity or morphology or unfavorable aneurysm morphology (e.g., determined from baseline or preprocedure imaging, or which may be evidenced by excessive resistance felt during the procedure) that would preclude safe endovascular access to the target aneurysm necessary for treatment with the study device
• • 4. Has significant intracranial atherosclerotic disease or stenosis determined from baseline or pre-procedure imaging
• • 5. If the target intracranial aneurysm is classified as ruptured, patient is neurologically unstable or has a Hunt \& Hess Score of ≥ 3
• • 6. Has a history of intracranial vasospasm not responsive to medical therapy
• • 7. Has undergone coiling or stenting of a non-target intracranial aneurysm within 30 days prior to study treatment or has a non-target intracranial aneurysm that is expected to be treated within 12 months following the treatment of the target aneurysm
• • 8. Treatment with flow diverting stent implant is anticipated
• • 9. A planned, staged procedure is anticipated
• • 10. Has Moya-Moya disease, arteriovenous malformation(s), arteriovenous fistula(e), intracranial tumor(s), intracranial hematoma(s), any other intracranial vascular malformation, or any previous major intracranial surgery
• • 11. Has had a recent (within 90 days) ischemic stroke, TIA, or intracranial hemorrhage
• • 12. Has a baseline mRS score ≥2
• • 13. Has a known coagulopathy or is on chronic anticoagulant therapy
• • 14. Is pregnant or intends to become pregnant during the study or is breastfeeding
• • 15. Is concurrently involved in another study that could affect outcomes of IA treatment
• • 16. Has evidence of active cancer, terminal illness, high risk of embolic stroke, unstable atrial fibrillation, significant co-morbidities, major surgery ≤ 30 days pre-procedure, psychiatric disorders, substance abuse, or a life expectancy of less than 5 years
• • 17. Has a contraindication to angiography, radiographic contrast agents, or any medications that are typically used during the procedure, and any other contraindications listed in the Investigational DFU
• • 18. Has a confirmed allergy to platinum, tungsten, nickel (e.g. nitinol), or other elements used in the manufacturing of the investigational device
