Clip for LAA closuRe: Evaluating the Safety and Effectiveness of the ECLIPTIS Exclusion sYstem (CLAARITY Study)

CLAARITY is a prospective, observational, single-arm, multi-center, post-market US study designed to evaluate the safety and performance of the ECLIPTIS clip in a minimum of 168 participants.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Not yet recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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

Subjects in the CLAARITY study will be enrolled at up to 15 sites in the United States. The population will be subjects who will be implanted with the ECLIPTIS clip who are eligible for LAA exclusion when undergoing concomitant open-heart cardiac surgical procedure according to its labeled Instructions for Use (IFU).

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
168

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The target population includes adult candidates who require exclusion of their left atrial appendage via a surgical clip while undergoing a concomitant cardiac surgical procedure.

Description

Inclusion Criteria:

  • ≥18 years old
  • Willing and able to provide consent and comply with study follow-up requirements
  • Scheduled to undergo concomitant open-heart cardiac surgery with planned implantation of ECLIPTIS clip for LAA exclusion per IFU

Exclusion Criteria:

  • Known life expectancy <1 year
  • Previous cardiac surgery (re-operation)
  • Prior LAA isolation attempts
  • Planned right thoracotomy approach
  • Concomitant open-heart surgery that is considered an emergency
  • Thrombus in left atrium/LAA that cannot be evacuated before placement of clip
  • Based on intraoperative evaluation, LAA is not appropriate for exclusion prior to positioning ECLIPTIS clip to the base of the LAA

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
Percentage of participants who have device technical success
Time Frame: Intra-operative
Successful ECLIPTIS clip placement and exclusion of LAA, defined as absence of flow (0 mm) between left atrium and LAA, and <10 mm of residual stump proximal to the clip at the time of the procedure assessed by intra-operative transesophageal echocardiogram (TEE) with Doppler.
Intra-operative
Participant's rate of major clinically significant adverse events
Time Frame: 30 days

Major clinically significant adverse events related to the ECLIPTIS clip and/or ECLIPTIS clip placement procedure within 30 days:

  • Death
  • Major bleeding
  • Major infection
  • Pericardial effusion requiring intervention
  • Myocardial infarction requiring intervention
  • Stroke, systemic embolism
30 days

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
Percentage of participants who have device technical success
Time Frame: 90 days
Size of any residual flow between the LA and LAA, degree of LAA involution and presence of thrombus at the LAA stump as assessed by CT angiography (CTA) at 90 day follow-up.
90 days
Participant's rate of major clinically significant adverse events over time
Time Frame: 90 days, 1, 2, and 3 years

Major clinically significant adverse events related to the ECLIPTIS clip and/or ECLIPTIS clip placement procedure annually through 3 years

  • Death
  • Major bleeding
  • Major infection
  • Pericardial effusion requiring intervention
  • Myocardial infarction requiring intervention
  • Stroke, systemic embolism
90 days, 1, 2, and 3 years

Primary Completion (Estimated)

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.
