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 Results may not be published yet.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

Summary

This study is a registry that will collect real-world data from 750 people with brain aneurysms treated with MicroVention devices. The goal is to see how well these devices work and how safe they are in everyday medical practice. Participants will be followed for at least one year to check aneurysm closure and any complications.

What this could mean

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

Active substance
Intracranial aneurysm treatment devices (MicroVention)
What this could lead to
If successful, this registry could provide real-world evidence on how well these devices work and their safety, helping doctors make better treatment decisions for brain aneurysms.
What could go wrong
This is an observational registry, not a controlled trial, so results may be influenced by patient selection and other factors. It does not test a new treatment, only collects data on existing devices.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Patient must have a single ruptured or unruptured IA for which endovascular treatment has been determined appropriate. 2. Patient's IA will be treated using a commercially available MicroVention implant device as the primary treatment device and the decision to use this device has been made by the treating physician outside the context of the CAR study and prior to enrollment. Note: For the purposes of this protocol, ancillary/accessory devices such as balloon catheters and other access devices are not considered primary treatment devices. 3. Patient or patient 's legally authorized representative (LAR) has provided written informed consent prior to treatment or no later than 48 hours post procedure for emergent treatment of a ruptured aneurysm. 4. Patient must be considered by the treating physician to be available for and able to complete study follow-up visits. Exclusion Criteria: 1. Target aneurysm has been previously treated via surgical or endovascular means. 2. Patient is enrolled in another device or drug study in which participation could confound study results. 3. Patient has a life expectancy of less than 1 year due to other illness or condition (in addition to an intracranial aneurysm). 4. Patient has been previously enrolled into this study.
