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.

Study Type

119

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

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
Primary Patency at 12 Months
Time Frame: 12 months
Primary patency is defined as no evidence of restenosis (repeat narrowing) or occlusion (total blockage) within the originally treated lesion based on color-coded duplex sonography (color Doppler ultrasound (CDUS). The Peak Systolic Velocity Ratio must be less than 2.5 (PSVR: the result of taking the highest rate of blood flow within the stented region and dividing it by the highest rate of blood flow just above the stented area).
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Proportion of Subjects Who Experience Major Device-related Adverse Events Within the First 30 Days
Time Frame: 30 days
If the functioning or characteristics of the device caused or contributed significantly to the adverse event,and if they occurred within 30 days of the procedure, they would be considered major adverse events (MAEs). Major AEs require significant therapy, including an unplanned increase in the level of care, permanent sequelae, hospitalization, or death.
30 days
Primary Assisted Patency
Time Frame: 12 months
Primary assisted patency is defined as patency in the target lesion maintained by repeat intervention (one or more follow-up procedures) in an attempt to salvage the stent prior to complete occlusion (blockage) of the treated arterial segment, and also includes patients with primary patency.
12 months
Secondary Patency
Time Frame: 12 months
Secondary patency is defined as patency in the target lesion maintained by repeat intervention (one more more follow-up procedures) after complete occlusion (blockage) of the treated arterial segment, and also includes patients that have primary and primary assisted patency.
12 months
Device-related Major Adverse Events at 12 Months
Time Frame: 12 months
If the functioning or characteristics of the device caused or contributed significantly to the adverse event (AE), the AE would be related to the device. Major AEs require significant therapy, including an unplanned increase in the level of care, permanent sequelae, hospitalization, or death.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
