Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Approximately 258 subjects with intracranial aneurysms would be enrolled for coiling embolization according to the inclusion and exclusion criteria specified in this trial protocol. Subjects were evaluated by mRS preoperatively, at the time of device implantation, at the time of discharge from the hospital, at 1 month (±7 days) postoperatively, at 6 months (±30 days) postoperatively, and at 12 months (±90 days) postoperatively; subjects would underwent DSA imaging at surgery and at 12months (±90 days) postoperatively, and MRA imaging at 18 months (±90 days) postoperatively. Unplanned follow-up of the subjects would performed when necessary, and data would be recorded to evaluate the safety and efficacy of Nufairy Coil Embolization System for coiling embolization for the treatment of intracranial aneurysms.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Successful occlusion rate of aneurysm at 12-month post-procedure.
Time Frame: 12 month
It was defined as the percentage of subjects with the degree of aneurysm embolization scored as Raymond I or II (i.e., 95%-100% aneurysm embolization).
