PREVAIL-TF: Transfemoral Placement of Aortic Balloon Expandable Transcatheter Valves Trial (Europe)

October 27, 2020 updated by: Edwards Lifesciences

Transfemoral Placement of AoRtic Balloon Expandable Transcatheter VAlves TrIaL (EUROPE)

A single arm, prospective multicenter non-randomized confirmatory clinical trial evaluating the Edwards SAPIEN XT™ transcatheter heart valve (model 9300TFX; "study valve"), its transfemoral delivery system, and crimper accessories. The trial includes a premarket confirmatory cohort to evaluate the system performance as well as a Post Market Clinical Follow-up phase involving expanded enrollment and long-term follow-up of all patients to evaluate valve performance out to 5 years.

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

Edwards Lifesciences obtained CE marking authorization for transfemoral delivery / implantation of the Edwards SAPIEN™ transcatheter heart valve (model 9000TFX) using the RetroFlex™ delivery system in August 2007 and introduced these devices for commercial distribution in the European Economic Area (EEA) in October 2007.

Clinical Sites: Up to 11 sites in Europe

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

Genders Eligible for Study

All

Description

Inclusion Criteria:

All candidates for this study must meet all of the following inclusion criteria:

  1. Patients must have co-morbidities such that the surgeon (Co Investigator) and interventional cardiologist (Principal Investigator) concur that the predicted risk of operative mortality is > 15% with a minimum STS Risk Calculator score of ≥ 10 and/or Logistic EuroSCORE of > 20%.
  2. Patient is symptomatic from his/her aortic valve stenosis, as demonstrated by NYHA Functional Class II or greater.
  3. The subject or the subject's legal representative has been informed of the nature of the study, agrees to its provisions and has provided a written informed consent that has been approved by the reviewing Ethics Committee (EC) of the respective clinical site.
  4. Subject is willing to comply with specified follow up evaluations, including possible coronary angiography and transesophageal echocardiography.
  5. The subject and the treating physician agree that the subject will return for all required post-procedure follow-up visits.

Exclusion Criteria:

  1. Aortic valve is a congenital unicuspid or bicuspid valve, or is non-calcified.
  2. Mixed aortic valve disease (aortic stenosis and aortic regurgitation with predominant aortic regurgitation >3+).
  3. Any therapeutic invasive cardiac procedure, other than BAV, performed within 30 days of the index procedure (or 6 months if the procedure was a drug eluting coronary stent implantation).

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
Number of Deaths
Time Frame: 30 days
Number of death at 30-days from the index procedure.
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
Number of Participants With a Stroke
Time Frame: 30 days from the index procedure

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
