Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • All candidates for this study must meet all of the following inclusion criteria:
  • Age ≥18 years
  • Heart Failure with NYHA class ≥ 2
  • Under appropriate and stable guideline-directed HF therapy for a minimum of 1 month prior to randomization.
  • Note: Patients are expected to be on appropriate pharmacologic therapy and if indicated CRT for heart failure. (12, 13) Patients with aortic stenosis may not be able to tolerate maximal doses of heart failure medications and no specific guidelines exist for the medical treatment of heart failure in the setting of aortic stenosis. It is expected that the heart failure PI will review the medical therapy and confirm that it is appropriate for the patient's condition.
  • Moderate AS confirmed by the echo core lab. Moderate AS is defined as an aortic valve area (AVA) >1.0 cm2 and ≤1.5 cm2 on rest echo or if ≤1.0 cm2 at rest and low-flow AS is suspected when the an AVA > 1.0 cm2 with low dose dobutamine stress echo (DSE). Patients with AVA<1.0 cm2 but with an indexed AVA of >0.6 cm2/m2 on either rest or DSE are also eligible. Similarly, patients with AVA >1.5 cm2 but with indexed AVA<0.9 cm2/m2 on either rest of DSE are also eligible.

  • Note: Typically such cases will demonstrate,
  • Mean trans-aortic gradient (MG) ≥ 20 mmHg and < 40 mmHg at rest and aortic valve area (AVA) > 1.0 cm2 and ≤1.5 cm2 (or AVA < 1.0 cm2 but indexed AVA > 0.6 cm2) at rest
  • OR
  • Mean trans-aortic gradient (MG) ≥ 20 mmHg and < 40 mmHg and aortic valve area (AVA) ≤1.0 cm2 at rest AND MG < 40 mmHg and aortic valve area (AVA)
  • •>1.0 cm2 (or AVA < 1.0 cm2 but indexed AVA > 0.6 cm2) with low dose dobutamine stress echo (DSE).
  • In atypical cases (for example mean gradient is below 20 mmHg but valve area is consistent with moderate AS, the final eligibility determination in regards to diagnosis of moderate AS will be made by the echocardiographic core lab.
  • Left ventricular (LV) ejection fraction (EF) < 50% at rest
  • Anatomically suitable for transfemoral TAVR with the SAPIEN 3 or SAPIEN 3 Ultra THV
  • Able to provide independent informed consent (i.e., not requiring a legally authorized representative)

Questions about this trial

What is this clinical trial studying?

A study testing SAPIEN 3 THV and Optimal Heart Failure Therapy in people with Aortic Valve Stenosis, run by Cardiovascular Research Foundation, New York at 51 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 15 inclusion and 28 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: under way, not looking for participants, as of the sponsor's last update on 27 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 51 sites in United States, Netherlands, Canada. 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?

This study is still under way. Results are not available in the source record yet.

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?

All-Cause Death (time frame: 12 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02661451, which also lists 1 linked publication.

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 27 Nov 2024.
