About this study

Official title: Interventional Strategy to Abrogate Mitral Regurgitation Using the MitraClip System in High-Risk Patients Considered Unsuitable for Surgery (ISAR-CLIP)

The primary objective in this randomized trial is to evaluate the safety and efficacy of a MitraClip treatment in symptomatic patients with severe mitral regurgitation in comparison to the previous default medical treatment - in a study population who is not amenable for the conventional surgical approach as current gold standard.

Read the detailed description

The presence of a significant mitral regurgitation (MR) seriously effects the patient's quality of life and is associated with an increased mortality rate. The operative treatment of MR - either mitral valve repair or replacement - is the current gold standard. However mere half of the patients with a severe and symptomatic MR actually undergo an operative treatment (EURO-HEART-SURVEY) due to restricted left ventricular ejection fraction, elderly patients with co-morbidities and high perioperative morbidity and mortality. In contrast, patients with severe and symptomatic MR not suitable for operation are treated with palliative medical therapy (heart insufficiency therapy). With the development of the MitraClip device - a minimal-invasive, percutaneous catheter-based technique - high-risk patients not suitable for surgery may receive a promising alternative treatment by approximating the mitral leaflets, thus creating a permanent leaflet coaptation and reducing or even abrogating the MR. The current data support the assumption of a safe and effective MR reduction with the MitraClip-System in inoperable high-risk patients with severe MR. But the feasibility still has to be proven in this special patient population.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • percutaneous treatment by implanting a Mitra Clip deviceDevice

    Also called Mitra Clip system

    With a minimal-invasive, percutaneous catheter-based technique and trans-septal approach under transesophageal echocardiographic and fluoroscopic guidance, the MitraClip device grasps and approximates the mitral leaflets thus creating a double-orifice mitral valve with a permanent leaflet coaptation and a reduction or even abrogation of mitral regurgitation.

What is being measured

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

  1. Improvement of Dyspnoea of at least one class (NYHA-Classification)

    Measured: after 6 months

Secondary outcomes (1)
  1. composite endpoint and clinical outcome measured by NYHA-classification

    • composite endpoint (death of any cause, myocardial infarction, stroke, sepsis, TIMI major bleeding, clip embolisation, partial clip detachement, acute renal failure)
    • unscheduled hospitalization due to increased heart insuffiecency
    • changes in quality of life
    • echocardiographic parameters
    • loboratory parameters
    • resiliance measured by spiroergometry

    Measured: 1 year and 2 years after intervention

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing percutaneous treatment by implanting a Mitra Clip device in people with Mitral Regurgitation, run by Deutsches Herzzentrum Muenchen at 1 site in Germany.

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 6 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 9 Sep 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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

Contact Joerg Hausleiter, MD (+49-89-1218-0 ext. 4018, hausleiter@dhm.mhn.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Improvement of Dyspnoea of at least one class (NYHA-Classification) (time frame: after 6 months). 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 9 Sep 2011.
