Early neo2 Registry of the Acurate neo2 TAVI Prosthesis

October 3, 2022 updated by: Andreas Rück
The Early neo2 registry will study up to 500 patients treated with the updated Boston Acurate neo2 TAVI prosthesis at various European hospitals. The data is gathered from routine healthcare and there are no study-mandated additional procedures. The main endpoint is a combined efficiency and safety endpoint after 30 days. Imaging data (echocardiography, computed tomography and aortography) will be analysed centrally by a core lab.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Background and rationale The Boston Scientific Acurate neo2 TAVI prosthesis was launched commercially in Europe in September 2020 as a successor to the original Acurate neo prosthesis. Modifications include an added sealing skirt. The original Acurate neo failed to reach non-inferiority to other TAVI prostheses in two randomized trials. There is a need to gather initial safety and efficacy data from this next generation prosthesis, as there is no larger dataset presented after the CE-mark study of the Acurate neo2.

Project objectives To gather initial safety and efficacy data in the initial up to 500 consecutive patients treated with the Acurate neo2 in various European sites.

Karolinska will be the coordinating center for data collection.

Methods Data will be collected in an anonymous form and sent to Karolinska for compilation and statistics. Data collection will continue until 500 patients are reached (April, 2021).

Statistics Standard descriptive statistics will be used for the main results. For the comparison to SCOPE data (with the original Acurate neo prosthesis) on postoperative aortic insufficiency, standard statistical methods will used (Fishers exact test for categorical variables, and t-test for continuous measurements such as amount of regurgitation by videodensitometry).

Core lab studies The core lab analyses will be performed at CORRIB in Galway (Prof. Serruys et al).

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

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
MACE
Time Frame: 30 days

any of

  • Postoperative aortic insuffiency moderate or higher (in hospital echo, site reported)
  • Postoperative new permanent pacemaker (in hospital)
  • 30 days mortality
  • 30 days stroke
  • Acute Kidney Injury (AKIN grade 3) (in hospital)
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
Rate of Postoperative aortic insufficiency more than mild by transthoracic echo
Time Frame: Within 7 days of procedure
Core-lab analysis of the postoperative transthoracic echo for aortic insufficiency: percentage of patients with more than mild insufficiency
Within 7 days of procedure
Rate of Postoperative aortic insufficiency more than mild by aortography
Time Frame: Same day as procedure
Core-lab analysis of the aortogram in the end of the procedure for quantification of aortic insufficiency (videodensitometry): rate of patients with more than mild insuffiency
Same day as procedure
Postoperative aortic valve gradients
Time Frame: Within 7 days of procedure
Aortic prosthesis mean gradient (mmHg) on postoperative transthoracic echocardiogram
Within 7 days of procedure
Rate of major acute procedural complications
