  • Subject has untreated coronary artery disease, which in the opinion of the treating physician, is clinically significant and requires revascularization.
  • Subject has documented left ventricular ejection fraction <30%.
  • Subject is in cardiogenic shock or has hemodynamic instability requiring inotropic support or mechanical support devices.
  • Subject has severe vascular disease that would preclude safe access (e.g., aneurysm with thrombus that cannot be crossed safely, marked tortuosity, significant narrowing of the abdominal aorta, severe unfolding of the thoracic aorta, or symptomatic carotid or vertebral disease).
  • Subject has arterial access that is not acceptable for the LOTUS Edge delivery system and its compatible Lotus or iSleeve Introducers as defined in the Directions For Use, or severe iliofemoral tortuosity or calcification that would prevent safe placement of either introducer sheath.
  • Current problems with substance abuse (e.g., alcohol, etc.).
  • Subject is participating in another investigational drug or device study that has not reached its primary endpoint.
  • Subject does not have a permanent pacemaker but has a class I or II indication for pacemaker implantation (based on the latest available ESC guidelines).

About this study

Official title: REPRISE EDGE: REpositionable Percutaneous Replacement of NatIve StEnotic Aortic Valve Through Implantation of LOTUS EDGE Valve System - Evaluation of Performance and Safety

The objective of the REPRISE EDGE study is to confirm the acute performance and safety of the LOTUS Edge™ Valve System when used with the Lotus™ or iSleeve™ Introducer Set for transcatheter aortic valve implantation (TAVI) in symptomatic patients with severe calcific aortic stenosis who are considered high risk for surgical valve replacement.

Read the detailed description

This clinical study is a prospective, single-arm study designed to demonstrate that the acute performance and safety of the LOTUS Edge Valve System when used with the iSleeve or Lotus Introducer Set are consistent with the results of the commercially approved Lotus Valve System used in the REPRISE II study, when delivered and deployed in symptomatic subjects who have severe calcific aortic valve stenosis and who are at high risk for surgical aortic valve replacement (SAVR).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean aortic valve pressure gradient

    Mean aortic valve pressure gradient as measured by echocardiography and assessed by an independent core laboratory.

    Measured: At discharge from hospital or at 7 days post-procedure (whichever comes first)

Secondary outcomes (5)
  1. Technical success

    Defined as successful vascular access, delivery, and deployment of a Lotus Valve; successful retrieval with the delivery system; and correct positioning of a single Lotus Valve in the proper anatomical location (reported as percent of subjects implanted with a Lotus Valve). Reported as percent of subjects.

    Measured: Immediately post-procedure (patient discharged from operative room)

  2. Effective orifice area

    Effective orifice area as measured by echocardiography and assessed by an independent core laboratory

    Measured: At discharge from hospital or at 7 days post-procedure (whichever comes first)

  3. Successful repositioning of the study valve if repositioning is attempted

    Measured: Immediately post-procedure (patient discharged from operative room)

  4. Successful retrieval of the study valve if retrieval is attempted

    Measured: Immediately post-procedure (patient discharged from operative room)

  5. Grade of paravalvular aortic regurgitation

    Grade of paravalvular aortic regurgitation as measured by echocardiography and assessed by an independent core laboratory

    Measured: At discharge from hospital or at 7 days post-procedure (whichever comes first)

Questions about this trial

What is this clinical trial studying?

A study testing LOTUS Edge Valve System in people with Aortic Valve Stenosis, run by Boston Scientific Corporation at 3 sites in 3 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 31 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Denmark, France, Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Investigational Medical Device is not available and the 15 patients enrolled completed their 1-yr follow-up per protocol). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean aortic valve pressure gradient (time frame: At discharge from hospital or at 7 days post-procedure (whichever comes first)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 May 2018.
