What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only This study
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a drug-coated stent designed to block blood flow into unruptured brain aneurysms, helping them heal. Researchers will follow 280 patients for 12 months after the stent is placed, checking how well the aneurysm closes and watching for any complications. The goal is to confirm the stent is safe and works as intended.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Lattice Flow-Diverting Dense-Mesh Stent (a drug-eluting stent device)
What this could lead to
If successful, this stent could offer a safer, more effective way to treat unruptured brain aneurysms without open surgery.
What could go wrong
This is a post-marketing study, so the device is already approved. However, results may vary, and risks like incomplete healing or complications remain possible.

Inclusion Criteria:Inclusion Criteria Aged 18 years or older; Patients diagnosed with unruptured intracranial aneurysms via CTA (Computed Tomographic Angiography), MRA (Magnetic Resonance Angiography), or DSA (Digital Subtraction Angiography); Patients treated with the Lattice Flow-Diverting Dense-Mesh Stent; Patients with 12-month follow-up records after treatment with the Lattice Flow-Diverting Dense-Mesh Stent; Patients whose aneurysms and parent arteries meet the indications for the Lattice Flow-Diverting Dense-Mesh Stent. \- Exclusion Criteria:Patients with severe respiratory, circulatory, hepatic, renal diseases, or coagulation disorders; Patients whose target aneurysms are pseudoaneurysms, or aneurysms associated with arteriovenous malformations (AVMs) or Moyamoya disease; Patients with intracranial space-occupying lesions (such as intracranial tumors, abscesses, etc.), or those undergoing radiotherapy to the head; Patients currently participating in clinical trials of other drugs or medical devices; Patients with incomplete follow-up information 12 months after treatment with the Lattice Flow-Diverting Dense-Mesh Stent; Patients who express explicit disagreement (verbally or in writing) with participating in this study; Patients with parent artery stenosis greater than 50% that requires balloon angioplasty. \-
