About this study

Official title: A Study to Evaluate the Corvia Medical, Inc. IASD® System II to REDUCE Elevated Left Atrial Pressure in Patients With Heart Failure With Reduced Ejection Fraction

The objective of this pilot study is to evaluate the safety and performance of implanting the IASD® System II in Heart Failure patients with reduced ejection fraction and elevated left sided filling pressures, who remain symptomatic despite Guideline Directed Medical Therapy (GDMT).

Read the detailed description

The intended clinical indication of the IASD System II is the reduction of elevated LAP in patients with symptomatic heart failure with reduced ejection fraction, despite appropriate medical management. The implant is designed with a center barrel opening that, in the setting of elevated LAP, allows left to right flow. Since many of the symptoms these patients experience are believed to be due to elevated LAP, the IASD System II has the potential to significantly reduce symptoms and improve the quality of life in patients with otherwise limited treatment options.

The study design is a prospective, non-randomized, single-arm feasibility trial. This study will implant up to 10 subjects. The population will include heart failure patients with reduced ejection fraction, and elevated left sided filling pressures, who remain symptomatic despite GDMT, including optimal doses of recommended pharmaceutical treatments, surgical, and device intervention(s) (CRT, AICD, reduction of MRI). After analysis of the 1 month results (including baseline and 1 month Core laboratory echocardiographic and hemodynamic data) of the first 5 implanted patients, a decision will be made to implant an additional 5 patients,

What is being measured

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

  1. The percent of subjects who experience major adverse cardiac and/or cerebrovascular events (MACCE)

    The primary endpoint will be peri-procedural, and 6 months Major Adverse Cardiac and Cerebrovascular Events (MACCE) and systemic embolic events in patients implanted with the IASD.

    Measured: 6 months

  2. The percent of subjects who have successful device implantation

    Deployment at the intended location during the index procedure

    Measured: Index Procedure

  3. The percent of subjects left to right flow through the device

    Left to right flow through the device at 6 months as assessed by an echocardiographic core laboratory

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing IASD implant in people with Heart Failure, run by Corvia Medical at 4 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 39 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 6 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Australia, United States, Czechia. 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?

The percent of subjects who experience major adverse cardiac and/or cerebrovascular events (MACCE) (time frame: 6 months). The study lists 3 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 NCT03093961.

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 6 Feb 2024.
