About this study

Official title: High and Intermediate Risk Degenerative Mitral Regurgitation Treatment: A Randomized Controlled Trial Comparing MitraClip® to Surgical Therapy

The study is comparing MitraClip® to Surgical therapy in high and intermediate risk patients, who should be older than 18 years, and shall evaluate safety and efficacy of MitraClip® vs. surgery in high or intermediate risk patients. The patients will be randomised (MitraClip® or Surgery). The Study Follow-Up includes 4 visits after procedure (hospital discharge, 1, 6, 12 months post-procedure).

Read the detailed description

Two-arm, multi-centre, randomised prospective study comparing MitraClip® to Surgical therapy in high and intermediate risk patients. Patients should be older than 18 years and high and intermediate risk is defined by a score (for MV repair) >= 3% and <= 10% or as determined by the local Heart Team (which should include a surgeon and a cardiologist), based on the evidence that STS risk calculator may not identify all possible risk factors. Patients are selected upon clinical conditions and severity of MR. Anatomical feasibility is assessed by ECHO, according to the IFU (information for use).

The purpose of the trial is to evaluate safety and efficacy of MitraClip® vs. surgery in high and intermediate risk patients with DMR. Study Follow-Up includes the following visits after procedure: Hospital discharge, 1, 6, 12 months post-procedure.

Primary Endpoints are the 30-day safety superiority (ITT analysis) and the 12-month efficacy non-inferiority (ITT analysis) of the MitraClip®. The overall rate of Serious Adverse Events (SAEs) and Serious Adverse Device Events (SADEs) until 12 months and the MR Severity reduction at 6 and 12 month in the MitraClip® and Surgery groups are Secondary Endpoints

What participants receive

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

  • MitraClip®Device

    one or more (if needed) MitraClip® devices are placed on the leaflets of the mitral valve during catheterisation in a catheter laboratory

  • Mitral valve SurgeryProcedure or surgery

    Repair or replace mitral valve

Study groups in NCT02534155
Study groupRoleWhat they receive
MitraClip® TherapyActive comparatorMitraClip® system is a CE marked medical device, which consists of two parts (Clip Delivery System and Steerable Guide Catheter). It is a single sized, percutaneously implanted mechanical Clip. The MitraClip® device grasps and coapts the mitral valve leaflets resulting in fixed approximation of the mitral leaflets throughout the cardiac cycle. The procedure is performed in the cardiac catheterisation laboratory with echocardiographic and fluoroscopic guidance while the patient is under general anaesthesia.

Receives: Procedure: Mitral valve Surgery

What is being measured

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

  1. 30-day safety superiority (ITT analysis): Major Adverse Event Composite

    The study is powered to show superiority for safety of an endovascular treatment strategy with the MitraClip® as compared to a surgical treatment strategy. The primary safety endpoint is a Major Adverse Event Composite (MAE) including all-cause death, prolonged ventilation (>48h), renal failure, stroke and need for non-elective cardiovascular or thoracic surgery (defined as any kind of cardiovascular and thoracic surgery performed within 30 days from the index procedure and non anticipated prior to the procedure). The analysis of the primary safety endpoint is a test of superiority for the proportion of subjects free from the composite of safety events in the Device vs. the Surgery group at 30 days.

    Measured: 30 days

  2. 12-month efficacy non-inferiority (ITT analysis): Proportion of responders in the Device vs. the Surgery group

    The study is powered to show non-inferiority for clinical efficacy of an endovascular treatment strategy with the MitraClip® as compared to a surgical treatment strategy. The primary effectiveness endpoint is a test of non-inferiority for the proportion of responders in the Device vs. the Surgery group at 12 months. Patients are defined as responders if they are alive with at least a 1-grade improvement in NYHA Functional Class at 12 months over baseline and have not experienced a HF hospitalization within 12 months of randomization (MitraClip® procedure or Surgery).

    Measured: 12 month

Secondary outcomes (9)
  1. Overall rate of Serious Adverse Events (SAEs) and Serious Adverse Device Effects (SADEs) within 12 month

    Evaluation of all SAEs and SADEs that occur during the trial

    Measured: 12 month

  2. MR Severity reduction at 6 and 12 month

    MR (Mitral Regurgitation) Severity reduction at 6 and 12 months in the MitraClip® and Surgery groups

    Measured: between 6 and 12 month

  3. NYHA class changes at 6 and 12 months

    NYHA class changes at 6 and 12 months in the MitraClip® and Surgery groups

    Measured: between 6 and 12 month

  4. Change in 6MWT in 6 and 12 month

    Change in 6MWT (6 Minute Walking Test) in 6 and 12 months in the MitraClip® and Surgery groups

    Measured: between 6 and 12 months

  5. Change in Quality of Life in 6 and 12 months

    Change in Quality of Life (MLWHF) at 1,6 and 12 month in the MitraClip® and Surgery groups

    Measured: between 1 and 12 months

  6. Heart failure hospitalisation rate

    Heart failure hospitalisation rate in the post randomisation in the MitraClip® and Surgery groups

    Measured: during 12 months post procedure

  7. Days alive and out of hospital

    Days alive and out of hospital in the 12 months post-randomisation in the MitraClip® and Surgery groups

    Measured: during 12 months post procedure

  8. Hospital resources utilisations

    Hospital resources utillizations: length of stay post-procedure, ICU beds occupancy, need for rehabilitation services

    Measured: during 12 months post procedure

  9. Change in Quality of Life (SF36) in 6 and 12 months

    Change in SF36 at 1,6 and 12 month in the MitraClip® and Surgery groups

    Measured: between 1 and 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing MitraClip® and Mitral valve Surgery in people with Mitral Valve Insufficiency, run by University of Zurich at 12 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 14 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 9 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in Germany, Italy, Switzerland. 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?

The study was stopped early. 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?

30-day safety superiority (ITT analysis): Major Adverse Event Composite (time frame: 30 days). The study lists 2 primary outcomes in all. 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 2016.
